IMPORTANT NOTICE TO SHAREHOLDERS OF

NUVEEN AMT-FREE MUNICIPAL INCOME FUND (NEA, NEA PRC)

NUVEEN PREMIER MUNICIPAL OPPORTUNITY FUND, INC. (NIF)

AND

NUVEEN PREMIUM INCOME MUNICIPAL OPPORTUNITY FUND (NPX)

(EACH, A “FUND” AND COLLECTIVELY, THE “FUNDS”)

, 2012

Although we recommend that you read the complete Joint Proxy Statement/Prospectus, for your convenience, we have provided a brief overview of the issues to be voted on.

Q. | Why am I receiving this Joint Proxy Statement/Prospectus?

A. | You are receiving this Joint Proxy Statement/Prospectus in connection with the special shareholder meetings of the Funds, at which a proposal regarding the reorganization of your Fund will be considered.

Q. | What actions has each Fund’s Board of Trustees or Board of Directors (the “Board”) approved?

A. | The Board of Nuveen’s municipal closed-end funds has approved a series of mergers of municipal closed-end funds, including the reorganization of each of Nuveen Premier Municipal Opportunity Fund, Inc. (“Premier Opportunity”) and Nuveen Premium Income Municipal Opportunity Fund (“Premium Opportunity” and together with Premier Opportunity, the “Acquired Funds” and each, an “Acquired Fund”) into Nuveen AMT-Free Municipal Income Fund (the “Acquiring Fund”) (each, a “Reorganization” and together, the “Reorganizations”).

Q. | Why has each Fund’s Board recommended these proposals?

A. | Each Fund’s Board has determined that the proposed Reorganizations would be in the best interests of its respective Fund. Each Fund’s Board considered the Reorganizations as part of a broad initiative to rationalize the product offerings of Nuveen Funds and eliminate overlapping products. The Acquiring Fund and the Acquired Funds have similar investment objectives and policies and substantially similar portfolio compositions. The proposed Reorganizations are intended to result in lower operating expenses per common share (excluding costs of leverage) as a result of the larger size of the combined fund and to enhance the secondary trading market for common shares of the Funds as a result of the greater share volume of the combined fund. Although the anticipated total annual operating expenses per common share of the combined fund (including the costs of leverage) are expected to be higher for each Acquired Fund due to the increased levels of leverage and higher proportion of fixed-rate leverage in the combined fund, such leverage may produce higher returns for common shares over time to the extent that the returns obtained from investing leverage proceeds exceed the costs of leverage.

Q. | What are the potential benefits of the Reorganizations to common shareholders?

A. | The investment adviser to the Funds and each Fund’s Board believe that the proposed Reorganizations are expected to offer the following potential benefits to common shareholders of the Funds:

| — |  | Lower fees and operating expenses per common share (excluding costs of leverage) from greater economies of scale as the combined fund’s size results in a lower effective

| management fee rate based on managed assets and allows fixed operating expenses to be spread over a larger asset base. As noted above, the anticipated total annual operating expenses per common share of the combined fund, (including the costs of leverage) are expected to be higher for each Acquired Fund due to the increased levels of leverage and higher proportion of fixed-rate leverage in the combined fund.

| — |  | Improved secondary market trading for common shares as the combined fund’s greater share volume is expected to result in increased market liquidity, which may lead to narrower bid-ask spreads and smaller trade-to-trade price movements. The potential for higher common share net earnings and enhanced total returns over time may increase investor interest in the combined fund which would result in increased market liquidity. In addition, Acquired Fund common shareholders may experience improved secondary market trading after the Reorganizations due to the nature of the Acquiring Fund’s investment objectives of investing primarily in municipal securities exempt from the federal alternative minimum tax applicable to individuals (the “AMT”), in addition to regular federal income taxes, as the AMT feature of the objectives, which is not currently in place with respect to the Acquired Funds, may appeal to a broader group of investors.

| — |  | Increased flexibility in managing the structure and costs of leverage over time for example, by enabling the larger combined fund to simultaneously employ, or modify allocations between, fixed rate and floating rate issues as issues mature and/or as the investment adviser’s market outlook changes. In contrast, a smaller stand alone fund would likely be limited to employing one type of leverage and to smaller issues.

Q. | How will preferred shareholders of the Acquiring Fund be impacted by the Reorganizations?

| The Acquiring Fund currently has one series of MuniFund Term Preferred Shares (“MTP Shares”) and one series of Variable Rate MuniFund Term Preferred Shares (“VMTP Shares”) outstanding, and these shares will remain outstanding following the Reorganizations. Each of the Acquired Funds currently has outstanding shares of Variable Rate Demand Preferred Shares (“VRDP Shares”). Upon the closing of the Reorganizations, preferred shareholders of each Acquired Fund will receive on a one-for-one basis newly issued preferred shares of the Acquiring Fund with substantially similar terms, as of the time of exchange, as the preferred shares of the Acquired Fund exchanged therefor. While preferred shares of the Acquiring Fund will rank on a parity to each other, there are differences between the different types of preferred shares, which are discussed in the Joint Proxy Statement/Prospectus. With respect to matters requiring all preferred shareholders to vote as a single class or common and preferred shareholders to vote together, following the Reorganizations, preferred shareholders of the Acquiring Fund will hold a smaller percentage of the outstanding preferred shares of the combined fund.

Q. | Will the Reorganizations impact Fund distributions to common shareholders?

A. | The Reorganizations are not expected to adversely impact distributions to common shareholders and are expected to result in the same or higher distribution rates for common shareholders of each Fund (as common shareholders of the Acquiring Fund following the Reorganizations) as a result of lower operating expenses per common share (excluding the costs of leverage).

2

Q. | Do the Funds have similar investment objectives and policies?

A. | The Funds have similar investment objectives, policies and risks. Each Fund invests primarily in municipal securities and other related investments the income from which is exempt from regular federal income tax and, with respect to the Acquiring Fund, from the federal AMT. Each Fund emphasizes investments in investment grade municipal securities. Each Fund is a diversified, closed-end management investment company, and currently engages in leverage through the issuance of preferred shares and the use of inverse floating rate securities.

Q. | What specific proposals will I be asked to vote on in connection with a proposed Reorganization?

A. | Generally, shareholders of each Acquired Fund will be asked to vote on an Agreement and Plan of Reorganization with common shareholders and preferred shareholders voting as a single class and preferred shareholders voting separately. Shareholders of the Acquiring Fund will be asked to vote on the issuance of additional common shares in connection with the Reorganizations, with common and preferred shareholders voting as a single class and common shares voting separately. In addition, preferred shareholders of the Acquiring Fund will be asked to vote on the Agreement and Plan of Reorganization.

Q. | Will shareholders of the Acquired Funds receive new shares in exchange for their current shares?

A. | Yes. Upon the closing of the Reorganizations, each Acquired Fund will transfer substantially all of its assets to the Acquiring Fund in exchange for common and preferred shares of the Acquiring Fund, and the assumption by the Acquiring Fund of substantially all of the liabilities of such Acquired Fund. Each Acquired Fund will then be liquidated, dissolved and terminated in accordance with applicable law.

| Acquired Fund shareholders will become shareholders of the Acquiring Fund. Holders of common shares of each Acquired Fund will receive newly issued common shares of the Acquiring Fund, the aggregate net asset value of which will be equal to the aggregate net asset value of the common shares of the Acquired Fund held as of the close of trading on the business day immediately prior to the closing of the Reorganizations (including for this purpose fractional Acquiring Fund common shares to which shareholders would be entitled). Fractional shares will be sold on the open market and shareholders will receive cash in lieu of such fractional shares. Holders of preferred shares of each Acquired Fund will receive on a one-for-one basis newly issued preferred shares of the Acquiring Fund having substantially similar terms, as of the closing of the Reorganizations, as the Acquired Fund shares exchanged therefor.

| Current shareholders of the Acquiring Fund will remain shareholders of the Acquiring Fund.

Q. | Do the Reorganizations constitute a taxable event for the Acquired Funds’ shareholders?

A. | No. Each Reorganization is intended to qualify as a tax-free “reorganization” for federal income tax purposes. It is expected that you will recognize no gain or loss for federal income tax purposes as a direct result of a Reorganization, except that gain or loss may be recognized

3

| with respect to any cash received in lieu of fractional Acquiring Fund common shares. Prior to the closing of the Reorganizations, each Acquired Fund expects to declare a distribution of all of its net investment income and net capital gains, if any. Such a distribution may be taxable to an Acquired Fund’s shareholders for federal income tax purposes. To the extent that an Acquired Fund’s portfolio securities are sold in connection with a Reorganization, such Acquired Fund may realize gains or losses, which may increase or decrease the net capital gains or net investment income to be distributed by the Acquired Fund. However, since each Acquired Fund’s current portfolio composition is substantially similar to that of the Acquiring Fund and no Acquired Fund currently holds portfolio securities subject to the federal AMT, it is not currently expected that any significant portfolio sales will occur solely in connection with the Reorganizations (less than 5% of the assets of each Acquired Fund).

Q. | What will happen if the required shareholder approvals in connection with a Reorganization are obtained for one Fund but not for the other Funds?

A. | The closing of each Reorganization is contingent upon the closing of all of the Reorganizations. Because the closing of the Reorganizations is contingent on both of the Acquired Funds and the Acquiring Fund obtaining the requisite shareholder approvals and satisfying their other closing conditions, it is possible that your Fund’s Reorganization will not occur, even if shareholders of your Fund approve the Reorganization and your Fund satisfies all of its closing conditions, if one or more of the other Funds do not obtain their requisite shareholder approvals or satisfy their closing conditions. If all the shareholder approvals are not obtained, each Fund’s Board may take such actions as it deems in the best interests of such Fund, including conducting additional solicitations with respect to the proposals or continuing to operate the Fund as a stand-alone fund.

Q. | Will I have to pay any fees or expenses in connection with the Reorganizations?

A. | The costs of the Reorganizations (whether or not consummated) will be allocated among the Funds ratably based on the relative expected benefits of the Reorganizations comprised of forecasted cost savings (excluding the costs of leverage) and distribution increases, if any, to each Fund during the first year following the Reorganizations. Common shareholders will indirectly bear the costs of the Reorganizations. The costs of the Reorganizations are estimated to be $320,000 for the Acquiring Fund, $45,000 for Premier Opportunity and $540,000 for Premium Opportunity. Preferred shareholders are not expected to bear any costs of the Reorganizations. The Reorganizations are expected to result in cost savings (excluding the costs of leverage) over time for the common shareholders of each Fund (as common shareholders of the Acquiring Fund following the Reorganizations).

Q. | What is the timetable for the Reorganizations?

A. | If the shareholder voting and other conditions to closing are satisfied (or waived), the Reorganizations are expected to take effect on or about , [20 ] or as soon as practicable thereafter.

Q. | How does the Board recommend that I vote on the Reorganizations?

A. | After careful consideration, the Board has determined that the Reorganizations are in the best interests of each Fund and recommends that you vote FOR your Fund’s proposal(s).

JOINT PROXY STATEMENT/PROSPECTUS

NUVEEN AMT-FREE MUNICIPAL INCOME FUND (NEA, NEA PRC)

NUVEEN PREMIER MUNICIPAL OPPORTUNITY FUND, INC. (NIF)

AND

NUVEEN PREMIUM INCOME MUNICIPAL OPPORTUNITY FUND (NPX)

(EACH, A “FUND” AND COLLECTIVELY, THE “FUNDS”)

, 2012

This Joint Proxy Statement/Prospectus is being furnished to the common and preferred shareholders of Nuveen AMT-Free Municipal Income Fund (“AMT-Free Municipal” or the “Acquiring Fund”), and the common shareholders of Nuveen Premier Municipal Opportunity Fund, Inc. (“Premier Opportunity”) and Nuveen Premium Income Municipal Opportunity Fund (“Premium Opportunity”) (each, an “Acquired Fund” and together, the “Acquired Funds”), each a closed-end management investment company, in connection with the solicitation of proxies by each Fund’s Board of Trustees or Board of Directors, as applicable (each, a “Board” and each Trustee or Director, a “Board Member”) for use at a Special Meeting of Shareholders of each Fund to be held in the offices of Nuveen Investments, Inc. (“Nuveen” or “Nuveen Investments”), 333 West Wacker Drive, Chicago, Illinois 60606, on , , 2012, at _:00 _.m., Central time, and at any and all adjournments or postponements thereof (each, a “Special Meeting” and collectively, the “Special Meetings”) to consider the proposals listed below and discussed in greater detail elsewhere in this Joint Proxy Statement/Prospectus. AMT-Free Municipal and Premium Opportunity are each organized as a Massachusetts business trust. Premier Opportunity is organized as a Minnesota corporation. The enclosed proxy card and this Joint Proxy Statement/Prospectus are first being sent to shareholders of the Funds on or about , 2012. Shareholders of record of the Funds as of the close of business on October 31, 2012 are entitled to notice of, and to vote at, the Special Meeting and any and all adjournments or postponements thereof.

This Joint Proxy Statement/Prospectus explains concisely what you should know before voting on the proposals described in this Joint Proxy Statement/Prospectus or investing in the Acquiring Fund. Please read it carefully and keep it for future reference.

The securities offered by this Joint Proxy Statement/Prospectus have not been approved or disapproved by the Securities and Exchange Commission (“SEC”), nor has the SEC passed upon the accuracy or adequacy of this Joint Proxy Statement/Prospectus. Any representation to the contrary is a criminal offense.

On the matters coming before each Special Meeting as to which a choice has been specified by shareholders on the accompanying proxy card, the shares will be voted accordingly where such proxy card is properly executed, timely received and not properly revoked (pursuant to the instructions below). If a proxy is returned and no choice is specified, the shares will be voted FOR the proposals. Shareholders of a Fund who execute proxies may revoke them at any time before they are voted by

filing with that Fund a written notice of revocation, by delivering a duly executed proxy bearing a later date, or by attending the Special Meeting and voting in person. Merely attending the Special Meeting, however, will not revoke any previously submitted proxy.

The Board of each Fund has determined that the use of this Joint Proxy Statement/Prospectus for the Special Meetings is in the best interests of each Fund and its shareholders in light of the similar matters being considered and voted on by shareholders.

The following table indicates the proposals of each Fund for which the votes of common shareholders of each Fund and preferred shareholders of AMT-Free Municipal are being solicited pursuant to this Joint Proxy Statement/Prospectus and which shareholders are solicited to vote with respect to each matter. Except as otherwise noted below, the common shareholders of a Fund vote together with the preferred shareholders as a single class.

* | Holders of MuniFund Term Preferred Shares (“MTP Shares”) and Variable Rate MuniFund Term Preferred Shares (“VMTP Shares”) of the Acquiring Fund are being solicited through this Joint Proxy Statement/Prospectus. Premier Opportunity and Premium Opportunity are separately soliciting holders of their

ii

| Variable Rate Demand Preferred Shares (“VRDP Shares”) through a separate proxy statement and not through this Joint Proxy Statement/Prospectus on each of the foregoing proposals that require preferred shareholders to vote together with common shareholders as a single class or preferred shareholders to vote separately as a single class.

A quorum of shareholders is required to take action at each Special Meeting. A majority of the shares entitled to vote at each Special Meeting, represented in person or by proxy, will constitute a quorum of shareholders at that Special Meeting. Votes cast by proxy or in person at each Special Meeting will be tabulated by the inspectors of election appointed for that Special Meeting. The inspectors of election will determine whether or not a quorum is present at the Special Meeting. The inspectors of election will treat abstentions and “broker non-votes” (i.e., shares held by brokers or nominees, typically in “street name,” as to which (i) instructions have not been received from the beneficial owners or persons entitled to vote and (ii) the broker or nominee does not have discretionary voting power on a particular matter) as present for purposes of determining a quorum.

Those persons who were shareholders of record at the close of business on October 31, 2012 will be entitled to one vote for each share held and, with respect to holders of common shares, a proportionate fractional vote for each fractional common share held.

As of October 31, 2012, the shares of the Funds issued and outstanding were as follows:

Fund Ticker Symbol* |  | Common Shares |  | VRDP Shares |  |  | VMTP Shares |  |  | MTP Shares |
Acquiring Fund (NEA) |  |  |  |  | — |  |  |  | 676 |  |  |  | 8,300,000 |
Premier Opportunity (NIF) |  |  |  |  | 1,309 |  |  |  | — |  |  |  | — |
Premium Opportunity (NPX) |  |  |  |  | 2,190 |  |  |  | — |  |  |  | — |

* | The common shares of Premier Opportunity and Premium Opportunity are listed on the New York Stock Exchange (“NYSE”). The common shares of AMT-Free Municipal are listed on the NYSE MKT. Upon the closing of the reorganizations, it is expected that the common shares of the Acquiring Fund will be listed on the NYSE MKT. MTP Shares of the Acquiring Fund are listed on the NYSE under the ticker symbol NEA PrC. The VRDP Shares of Premier Opportunity and Premium Opportunity and the VMTP Shares of AMT-Free Municipal are not listed on any exchange.

The proposed reorganizations seek to combine three Funds that have similar investment objectives, policies and risks to achieve certain economies of scale and other operational efficiencies for the Funds (each, a “Reorganization” and together, the “Reorganizations”). The Agreement and Plan of Reorganization by and among each Acquired Fund and the Acquiring Fund (the “Agreement”) provides for: (i) the Acquiring Fund’s acquisition of substantially all of the assets of each Acquired Fund in exchange for newly issued common shares of the Acquiring Fund, par value $0.01 per share, and newly issued VRDP Shares of the Acquiring Fund, with a par value of $0.01 per share and a liquidation preference of $100,000 per share, and the Acquiring Fund’s assumption of substantially all of the liabilities of each Acquired Fund, and (ii) the distribution of the Acquiring Fund common shares and Acquiring Fund VRDP Shares received by each Acquired Fund to its common and preferred shareholders, respectively, as part of the liquidation, dissolution and termination of each Acquired Fund in accordance with applicable law. The aggregate net asset value of Acquiring Fund common shares received by each Acquired Fund in a Reorganization will equal, as of the Valuation Time (as such term is defined on page 21), the aggregate net asset value of Acquired Fund common shares held by shareholders of such Acquired Fund. Prior to the closing of the Reorganizations, the net asset value of each Acquired Fund and Acquiring Fund will be reduced by the costs of the Reorganization borne by such Fund. No fractional Acquiring Fund common shares will be issued to an Acquired Fund’s

iii

shareholders in connection with the Reorganizations and, in lieu of such fractional shares, an Acquired Fund’s shareholders will receive cash in an amount equal to the value received for such shares in the open market, which may be higher or lower than net asset value. VRDP shareholders of each Acquired Fund will receive the same number of Acquiring Fund VRDP Shares having substantially similar terms as the outstanding VRDP Shares of the Acquired Fund held by such preferred shareholders immediately prior to the closing of the Reorganizations. The aggregate liquidation preference of the Acquiring Fund VRDP Shares received in the Reorganizations will equal the aggregate liquidation preference of the corresponding Acquired Fund VRDP Shares held immediately prior to the Reorganizations.

All preferred shares of the Acquiring Fund to be issued in connection with the Reorganizations will have equal priority with each other and with the Acquiring Fund’s existing outstanding preferred shares as to the payment of dividends and as to the distribution of assets in the event of the Acquiring Fund’s liquidation. In addition, the preferred shares of the Acquiring Fund, including preferred shares of the Acquiring Fund to be issued in connection with the Reorganizations, will be senior in priority to the Acquiring Fund’s common shares, as to payment of dividends and as to the distribution of assets in the event of the Acquiring Fund’s liquidation. The Acquiring Fund will continue to operate after the Reorganizations as a registered closed-end management investment company with the investment objectives and policies described in this Joint Proxy Statement/Prospectus.

With respect to each Reorganization, the Reorganization is required to be approved by the affirmative vote of the holders of a majority of the outstanding shares of the Acquired Fund’s common shares and preferred shares, voting as a single class, and by the affirmative vote of a majority of the Acquired Fund’s outstanding preferred shares voting separately as a single class. Each Reorganization also is required to be approved by the affirmative vote of the holders of a majority of the Acquiring Fund’s outstanding preferred shares, voting separately as a single class. In addition, common and preferred shareholders of the Acquiring Fund voting as a single class, and common shareholders voting separately as a single class, are being asked to approve the issuance of additional common shares of the Acquiring Fund in connection with the Reorganizations.

The closing of each Reorganization is contingent upon the closing of both Reorganizations. In order for the Reorganizations to occur, each Fund must obtain all requisite shareholder approvals as well as certain consents, confirmations and/or waivers from various third parties, including liquidity providers and rating agencies with respect to outstanding preferred shares. Because the closing of the Reorganizations is contingent on each Acquired Fund and the Acquiring Fund obtaining the requisite shareholder approvals and satisfying (or obtaining the waiver of) other closing conditions, it is possible that your Fund’s Reorganization will not occur, even if shareholders of your Fund approve the Reorganization and your Fund satisfies all of its closing conditions. If the requisite shareholder approvals are not obtained, each Fund’s Board may take such actions as it deems in the best interest of such Fund, including conducting additional solicitations with respect to the proposals or continuing to operate the Fund as a stand-alone fund.

This Joint Proxy Statement/Prospectus concisely sets forth the information shareholders of the Funds should know before voting on the proposals and constitutes an offering of common shares of the Acquiring Fund only. Shareholders should read it carefully and retain it for future reference.

PROPOSAL NO. 1—REORGANIZATION OF EACH ACQUIRED FUND INTO

THE ACQUIRING FUND (COMMON SHAREHOLDERS OF EACH ACQUIRED FUND

AND PREFERRED SHAREHOLDERS OF THE ACQUIRING FUND)

A. | SYNOPSIS

The following is a summary of certain information contained elsewhere in this Joint Proxy Statement/Prospectus with respect to the proposed Reorganizations and is qualified in its entirety by reference to the more complete information contained in this Joint Proxy Statement/Prospectus and in the Reorganization SAI and the appendices thereto. Shareholders should read the entire Joint Proxy Statement/Prospectus carefully. Certain capitalized terms used but not defined in this summary are defined elsewhere in this Joint Proxy Statement/Prospectus.

Background and Reasons for the Reorganizations

The Board of Nuveen’s municipal closed-end funds has approved a series of mergers of municipal closed-end funds, including the reorganization of each of the Acquired Funds into the Acquiring Fund. Each Board has determined that the Reorganization proposed for its Fund would be in the best interests of such Fund. The Acquiring Fund and the Acquired Funds have similar investment objectives and policies, and substantially similar portfolio compositions. The proposed Reorganizations are intended to enhance the secondary trading market for common shares of the Funds and to result in lower operating expenses per common share (excluding the costs of leverage) as a result of the larger size of the combined fund. Although the anticipated total annual operating expenses per common share of the combined fund are expected to be higher for each Acquired Fund due to the increased levels of leverage and higher proportion of fixed-rate leverage in the combined fund, such leverage may produce higher returns for common shares over time. In order for the Reorganizations to occur, each Fund must obtain the requisite shareholder approvals as well as certain consents, confirmations and/or waivers from various third parties, including liquidity providers and rating agencies with respect to outstanding preferred shares. Because the closing of the Reorganizations is contingent on all of the Acquired Funds and the Acquiring Fund satisfying (or obtaining the waiver of) their respective closing conditions, it is possible that your Fund’s Reorganization will not occur, even if shareholders of your Fund approve the Reorganization and your Fund satisfies all of its closing conditions. If the requisite shareholder approvals are not obtained, each Fund’s Board may take such actions as it deems in the best interest of the Fund including conducting additional solicitations with respect to the proposals or continuing to operate the Fund as a stand-alone fund. For a fuller discussion of the Boards’ considerations regarding the approval of the Reorganizations, see “Proposal No. 1—Information About the Reorganizations—Reasons for the Reorganizations.”

Material Federal Income Tax Consequences of the Reorganizations

As a condition to closing, the Funds will receive an opinion of Vedder Price P.C., subject to certain representations, assumptions and conditions, substantially to the effect that each proposed Reorganization will qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). In addition, Sidley Austin LLP, as special tax counsel to the Acquiring Fund, will deliver an opinion to the Acquiring Fund, subject to certain representations, assumptions and conditions, substantially to the effect that the Acquiring Fund VRDP Shares received in the Reorganizations by holders of the VRDP Shares of the Acquired Funds will qualify as equity in the Acquiring Fund for federal income tax purposes. Accordingly, it is expected that no Fund will recognize gain or loss for federal income tax purposes as a direct result of the Reorganizations. It is also expected that shareholders of each Acquired Fund who receive Acquiring Fund common shares

pursuant to a Reorganization will recognize no gain or loss for federal income tax purposes, except that gain or loss may be recognized with respect to any cash received in lieu of fractional Acquiring Fund common shares being issued. Prior to the closing of the Reorganizations, each Acquired Fund expects to declare a distribution of all of its net investment income and net capital gains, if any. All or a portion of such distribution may be taxable to an Acquired Fund’s shareholders for federal income tax purposes. In addition, to the extent that an Acquired Fund’s portfolio securities are sold in connection with a Reorganization, such Acquired Fund may realize gains or losses, which may increase or decrease the net taxable dividends and capital gain to be distributed by the Acquired Fund. However, since each Acquired Fund’s current portfolio composition is substantially similar to that of the Acquiring Fund and neither Acquired Fund holds portfolio securities subject to the federal alternative minimum tax applicable to individuals (the “AMT”), it is not currently expected that any significant portfolio sales will occur solely in connection with the Reorganizations (less than 5% of the assets of each Acquired Fund).

Comparison of the Acquiring Fund and Each Acquired Fund

General. The Acquiring Fund and each Acquired Fund are closed-end management investment companies. Each Fund is a diversified management investment company. The common shares of the Acquiring Fund are listed and trade on the NYSE MKT. The common shares of Premier Opportunity and Premium Opportunity are listed and trade on the NYSE. The Acquiring Fund and Premium Opportunity were organized on July 29, 2002 and May 26, 1993, respectively, as business trusts under the laws of the Commonwealth of Massachusetts. Premier Opportunity was organized on October 31, 1991 as a corporation under the laws of the State of Minnesota. The common shares of each Fund have equal voting rights and equal rights with respect to the payment of dividends and the distribution of assets upon liquidation and have no preemptive, conversion or exchange rights or rights to cumulative voting.

The Acquiring Fund currently has outstanding 676 VMTP Shares, with a par value of $0.01 per share, a liquidation preference of $100,000 per share and a total liquidation value of $67,600,000, and 8,300,000 MTP Shares, with a par value of $0.01 per share, a liquidation preference of $10 per share and a total liquidation value of $83,000,000, which will remain outstanding following the completion of the Reorganizations. Premier Opportunity has 1,309 VRDP Shares outstanding, with a par value of $0.01 per share, a liquidation preference of $100,000 per share and a total liquidation value of $130,900,000. Premium Opportunity has 2,190 VRDP Shares outstanding, with a par value of $0.01 per share, a liquidation preference of $100,000 per share and a total liquidation value of $219,000,000. VMTP Shares, MTP Shares and VRDP Shares are entitled to one vote per share. Preferred shares issued by the Acquiring Fund in connection with the Reorganizations will have equal priority with each other and with outstanding preferred shares of the Acquiring Fund as to the payment of dividends and the distribution of assets in the event of the Acquiring Fund’s liquidation. In addition, preferred shares of the Acquiring Fund will have priority in all respects to the Acquiring Fund’s common shares, as to the payment of dividends and the distribution of assets upon liquidation. The Acquiring Fund VRDP Shares to be issued to the Acquired Funds pursuant to the Reorganizations will have rights and preferences, including liquidation preferences, that are substantially similar, as of the closing of the Reorganizations, to those of the outstanding Acquired Fund VRDP Shares for which they are exchanged.

Investment Objectives and Policies. The Funds have similar investment objectives and policies. The Acquiring Fund’s investment objectives are to provide current income exempt from regular federal income tax and the federal AMT and to enhance portfolio value relative to the

2

municipal bond market by investing in tax-exempt municipal bonds that the Fund’s investment adviser, Nuveen Fund Advisors, Inc. (“Nuveen Fund Advisors” or the “Adviser”), believes are underrated or undervalued or that represent municipal market sectors that are undervalued.

Premier Opportunity and Premium Opportunity have identical investment objectives, which are to provide current income exempt from regular federal income tax and to enhance portfolio value relative to the municipal bond market by investing in tax-exempt municipal bonds that the Adviser believes are underrated or undervalued or that represent municipal market sectors that are undervalued.

Under normal circumstances, the Acquiring Fund will invest at least 80% of its net assets, including assets attributable to any principal amount of any borrowings (including the issuance of commercial paper or notes) or any preferred shares outstanding (“Managed Assets”), in portfolio securities that pay interest exempt from regular federal income taxes and from federal AMT. Under normal circumstances, each Acquired Fund will invest at least 80% of its Managed Assets in a portfolio of securities that pay interest exempt from regular federal income taxes. The Acquired Funds do not have any policy regarding investments in securities subject to the federal AMT, and may have substantial holdings of securities subject to such tax.

The Acquiring Fund’s policy of investing in bonds that are exempt from the federal AMT may prevent the Acquiring Fund from investing in certain kinds of bonds that are held by, or are eligible investments for, the Acquired Funds.

Under normal circumstances, each Fund invests at least 80% of its Managed Assets in investment grade securities that, at the time of investment, are rated within the four highest grades (Baa or BBB or better) by at least one nationally recognized statistical rating organization (“NRSRO”) or are unrated but judged to be of comparable quality by the Adviser. Each Fund may invest up to 20% of its Managed Assets in municipal securities that at the time of investment are rated below investment grade or are unrated but judged to be of comparable quality by the Adviser. No more than 10% of each Fund’s Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by the Adviser.

If a municipal security satisfies the ratings requirements described above at the time of purchase, a Fund will not be required to dispose of the security upon a downgrade.

Each Fund may enter into certain derivative instruments in pursuit of its investment objectives. Such instruments include financial futures contracts, swap contracts (including credit default swaps and interest rate swaps), options on financial futures, options on swap contracts, or other derivative instruments. A Fund may not enter into a futures contract or related options or forward contracts if more than 30% of the Fund’s net assets would be represented by futures contracts or more than 5% of the Fund’s net assets would be committed to initial margin deposits and premiums on future contracts or related options.

Each Fund may invest in inverse floating rate securities. The Acquiring Fund may invest up to 15% of its net assets in inverse floating rate securities, while each Acquired Fund may invest up to 15% of its Managed Assets in inverse floating rate securities. Inverse floating rate securities represent a leveraged investment in the underlying municipal bond deposited. Inverse floating rate securities offer the opportunity for higher income than the underlying bond, but will subject the Fund to the risk of lower or even no income if short-term interest rates rise sufficiently. By investing in an inverse floating rate security rather than directly in the underlying bond, the Fund will experience a greater

3

increase in its common share net asset value if the underlying municipal bond increases in value, but will also experience a correspondingly larger decline in its common share net asset value if the underlying bond declines in value.

Each Fund may borrow money for the repurchase of its shares or for temporary or emergency purposes, such as for the payment of dividends or the settlement of portfolio transactions.

Credit Quality. A comparison of the credit quality of the respective portfolios of the Acquiring Fund and the Acquired Funds, as of April 30, 2012, is set forth in the table below.

Credit Rating(1) |  | Acquiring Fund |  |  | Premier Opportunity |  |  | Premium Opportunity |  |  | Combined Fund Pro Forma(2) |
Aaa/AAA |  |  | 31% |  |  |  | 28% |  |  |  | 22% |  |  |  | 26% |
Aa/AA |  |  | 30% |  |  |  | 46% |  |  |  | 48% |  |  |  | 42% |
A/A |  |  | 28% |  |  |  | 15% |  |  |  | 22% |  |  |  | 22% |
Baa/BBB |  |  | 7% |  |  |  | 9% |  |  |  | 8% |  |  |  | 8% |
Ba/BB or Lower |  |  | 2% |  |  |  | 1% |  |  |  | —% | (3) |  |  | 1% |
Unrated |  |  | 2% |  |  |  | 1% |  |  |  | —% | (3) |  |  | 1% |
TOTAL |  |  | 100% |  |  |  | 100% |  |  |  | 100% |  |  |  | 100% |

(1) | Prior to January 2, 2012, each Fund had a policy of investing, under normal circumstances, at least 80% of its Managed Assets in municipal securities covered by insurance guaranteeing the timely payment of interest and principal. Each Fund also had a policy of investing in municipal securities rated at least investment grade. The portfolio composition of the Funds may vary over time as a result of the new policies of the Fund.

(2) | Reflects the effect of the Reorganizations.

(3) | Rounds to less than 1%.

Leverage. Each Fund may utilize the following forms of leverage: (a) portfolio investments that have the economic effect of leverage, including but not limited to investments in futures, options and inverse floating rate securities, and (b) the issuance of preferred shares. Each Fund currently engages in leverage through the issuance of preferred shares and the use of inverse floaters. Certain important ratios related to each Fund’s use of leverage for the last three fiscal years for which financial statements are available are set forth below:

Acquiring Fund |  | 2011 |  |  | 2010 |  |  | 2009 |
Asset Coverage Ratio |  |  | 317.07 | % |  |  | 321.50 | % |  |  | 315.52 | %
Regulatory Leverage Ratio(1) |  |  | 31.54 | % |  |  | 31.10 | % |  |  | 31.69 | %
Effective Leverage Ratio(2) |  |  | 37.91 | % |  |  | 37.45 | % |  |  | 38.16 | %

Premier Opportunity |  | 2011 |  |  | 2010 |  |  | 2009 |
Asset Coverage Ratio |  |  | 319.30 | % |  |  | 324.41 | % |  |  | 314.65 | %
Regulatory Leverage Ratio(1) |  |  | 31.32 | % |  |  | 30.82 | % |  |  | 31.78 | %
Effective Leverage Ratio(2) |  |  | 38.57 | % |  |  | 38.51 | % |  |  | 37.72 | %

Premium Opportunity |  | 2011 |  |  | 2010 |  |  | 2009 |
Asset Coverage Ratio |  |  | 330.94 | % |  |  | 330.75 | % |  |  | 321.04 | %
Regulatory Leverage Ratio(1) |  |  | 30.22 | % |  |  | 30.23 | % |  |  | 31.15 | %
Effective Leverage Ratio(2) |  |  | 36.96 | % |  |  | 36.98 | % |  |  | 37.71 | %

(1) | Regulatory leverage consists of preferred shares or debt issued by the Fund. Both of these are part of a Fund’s capital structure. Regulatory leverage is sometimes referred to as “1940 Act Leverage” and is subject to asset coverage limits set forth in the 1940 Act.

(2) | Effective leverage is a Fund’s effective economic leverage, and includes both regulatory leverage and the leverage effects of certain derivative investments in the Fund’s portfolio. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings, in addition to any regulatory leverage, are included in effective leverage ratios.

Board Members and Officers. The Acquiring Fund and the Acquired Funds have the same Board Members and officers. The management of each Fund, including general supervision of the duties performed by the Adviser under an investment management agreement between the Adviser and each Fund (an “Investment Management Agreement”), is the responsibility of its Board. Each Fund currently has ten (10) trustees or directors, one (1) of whom is an “interested person” (as defined in the 1940 Act) and nine (9) of whom are not interested persons (the “independent directors/trustees”). The names and business addresses of the Board Members and officers of the Funds and their principal occupations and other affiliations during the past five years are set forth in the Reorganization SAI under “Management of the Funds.”

While the Acquiring Fund and Acquired Funds have the same Board Members, the Acquiring Fund and Premium Opportunity (the “Massachusetts Funds”) have a board structure that is different from the structure for Premier Opportunity (the “Minnesota Fund”). All members of the Board of Directors of the Minnesota Fund stand for election each year. In contrast to the Minnesota Fund’s board structure, and pursuant to the Massachusetts Funds’ by-laws, the Board of Trustees of each Massachusetts Fund is divided into three classes (Class I, Class II and Class III) with staggered multi-year terms, such that only the members of one of the three classes stand for election each year. The staggered Board structure could delay for up to two years the election of a majority of the Board.

Investment Adviser. The Adviser, Nuveen Fund Advisors, is the investment adviser to each Fund and is responsible for investing each Fund’s assets. The Adviser oversees the management of each Fund’s portfolio, manages each Fund’s business affairs and provides certain clerical, bookkeeping and other administrative services. Nuveen Fund Advisors is located at 333 West Wacker Drive, Chicago, Illinois 60606.

The Adviser, a registered investment adviser, is a wholly-owned subsidiary of Nuveen Investments. Founded in 1898, Nuveen Investments and its affiliates had approximately $212 billion of assets under management as of June 30, 2012. On November 13, 2007, Nuveen Investments was acquired by investors led by Madison Dearborn Partners, LLC (the “MDP Acquisition”).

Nuveen Fund Advisors has selected its affiliate, Nuveen Asset Management, LLC (“Nuveen Asset Management” or the “Sub-Adviser”), located at 333 West Wacker Drive, Chicago, IL 60606, to serve as a sub-adviser to each of the Funds. Nuveen Asset Management manages the investment of the Funds’ assets on a discretionary basis, subject to the supervision of Nuveen Fund Advisors. Nuveen Asset Management, is a wholly-owned subsidiary of Nuveen Fund Advisors and was appointed as Sub-Adviser effective in January 2011 as part of an internal restructuring of the Adviser.

Each Fund is dependent upon services and resources provided by its Adviser, and therefore the Adviser’s parent, Nuveen Investments. Nuveen Investments significantly increased its level of debt in connection with the MDP Acquisition. While Nuveen Investments believes that monies generated from

5

operations and cash on hand will be adequate to fund debt service requirements, capital expenditures and working capital requirements for the foreseeable future, there can be no assurance that Nuveen Investments’ business will generate sufficient cash flow from operations or that future borrowings will be available in an amount sufficient to enable Nuveen Investments to pay its indebtedness (with scheduled maturities beginning in 2014) or to fund its other liquidity needs. Nuveen Investments believes that potential adverse changes to its overall financial position and business operations would not adversely affect its or its affiliate’s portfolio management operations and would not otherwise adversely affect its ability to fulfill its obligations to the Funds under the investment management agreements.

Pursuant to each Investment Management Agreement, each Fund’s management fee consists of two components—a complex-level component, based on the aggregate amount of all eligible fund assets managed by Nuveen Fund Advisors, and a fund-level component, based only on the amount of managed assets within such Fund. The pricing structure enables the Funds’ shareholders to benefit from growth in assets within each individual fund as well as from growth of complex-wide assets managed by Nuveen Fund Advisors.

The annual fund-level fee for each Fund, payable monthly, is calculated according to the following schedules:

Management Fee Schedule for the Acquiring Fund

Average Daily Managed Assets* |  | Fund-Level Fee Rate |
For the first $125 million |  |  | 0.4500 | %
For the next $125 million |  |  | 0.4375 | %
For the next $250 million |  |  | 0.4250 | %
For the next $500 million |  |  | 0.4125 | %
For the next $1 billion |  |  | 0.4000 | %
For $2 billion and over |  |  | 0.3750 | %

Management Fee Schedule for Premier Opportunity and Premium Opportunity

Average Daily Managed Assets* |  | Fund-Level Fee Rate |
For the first $125 million |  |  | 0.4500 | %
For the next $125 million |  |  | 0.4375 | %
For the next $250 million |  |  | 0.4250 | %
For the next $500 million |  |  | 0.4125 | %
For the next $1 billion |  |  | 0.4000 | %
For the next $3 billion |  |  | 0.3875 | %
For $5 billion and over |  |  | 0.3750 | %

The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. Each Fund pays all of its other costs and expenses of its operations, including compensation of its Board Members (other than those affiliated with the Adviser), custodian, transfer agency and dividend disbursing expenses, legal fees, expenses of independent auditors, expenses of repurchasing shares, expenses of issuing any preferred shares, expenses of preparing, printing and distributing shareholder reports, notices, proxy statements and reports to governmental agencies, and taxes, if any. For the services provided pursuant to an investment sub-advisory agreement, Nuveen Fund Advisors pays Nuveen Asset Management a fee,

6

payable monthly, equal to 38.4615% of the management fee (net of applicable breakpoints, waivers and reimbursements) paid by the Funds to Nuveen Fund Advisors.

Due to the increased size of the combined fund, the effective fund-level fee rate as a percentage of average daily Managed Assets for the combined fund is expected to be lower than the current effective fund-level fee rate for the Acquiring Fund and each of the Acquired Funds. Each Fund also pays a complex-level fee to Nuveen Fund Advisors, which is payable monthly and is in addition to the fund-level fee. The complex-level fee is based on the aggregate daily amount of eligible assets for all Nuveen sponsored funds in the U.S., as stated in the table below. As of June 30, 2012, the complex-level fee rate was 0.1731%.

The annual complex-level fee for each Fund, payable monthly, is calculated according to the following schedule:

Complex-Level Fee Rates

Complex-Level Managed Asset Breakpoint Level* |  | Effective Rate at Breakpoint Level |
$55 billion |  |  | 0.2000 | %
$56 billion |  |  | 0.1996 | %
$57 billion |  |  | 0.1989 | %
$60 billion |  |  | 0.1961 | %
$63 billion |  |  | 0.1931 | %
$66 billion |  |  | 0.1900 | %
$71 billion |  |  | 0.1851 | %
$76 billion |  |  | 0.1806 | %
$80 billion |  |  | 0.1773 | %
$91 billion |  |  | 0.1691 | %
$125 billion |  |  | 0.1599 | %
$200 billion |  |  | 0.1505 | %
$250 billion |  |  | 0.1469 | %
$300 billion |  |  | 0.1445 | %

* | For the fund-level and complex-level fees, managed assets include closed-end fund assets managed by the Adviser that are attributable to financial leverage. For these purposes, financial leverage includes the funds’ use of preferred stock and borrowings and certain investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities, subject to an agreement by the Adviser as to certain funds to limit the amount of such assets for determining managed assets in certain circumstances. The complex-level fee is calculated based upon the aggregate daily managed assets of all Nuveen Funds that constitute “eligible assets.” Eligible assets do not include assets attributable to investments in other Nuveen Funds or assets in excess of a determined amount (originally $2 billion) added to the Nuveen Fund complex in connection with Nuveen Fund Advisors’ assumption of the management of the former First American Funds effective January 1, 2011.

A discussion of the basis for the Board’s most recent approval of each Fund’s Investment Management Agreement and the Sub-Advisory Agreement will be included in the Fund’s Annual Report for the period ended October 31, 2012.

Portfolio Management. Subject to the supervision of Nuveen Fund Advisors, Nuveen Asset Management is responsible for execution of specific investment strategies and day-to-day investment

7

operations. Nuveen Asset Management manages the Funds using a team of analysts and a portfolio manager that focuses on a specific group of funds. Paul L. Brennan, CFA, CPA, is the portfolio manager of the Acquiring Fund and Premier Opportunity. Douglas J. White, CFA, is the portfolio manager of Premium Opportunity. Additional information regarding the portfolio managers’ compensation, other accounts managed and ownership of securities is contained in the Reorganization SAI. Douglas White has been the portfolio manager for Premium Opportunity since 2011. Paul Brennan has been the portfolio manager for the Acquiring Fund and Premier Opportunity since 2006, and Mr. Brennan will continue to manage the Acquiring Fund upon completion of the Reorganizations.

Paul Brennan is currently a portfolio manager for several national municipal open- and closed-end funds. Mr. Brennan joined Nuveen in 1997 when Nuveen acquired Flagship Financial.

Comparative Risk Information

Because the Funds have similar investment strategies, the principal risks of each Fund are similar. Each Fund is subject to credit risk, interest rate risk and other risks of investing primarily in a portfolio of municipal securities. Each Fund is subject to the risks associated with the use of inverse floating rate securities and the issuance of preferred shares. The principal risks of investing in the Acquiring Fund are described in more detail below. An investment in an Acquired Fund is also subject to each of these principal risks.

Comparative Expense Information

The purpose of the comparative fee table is to assist you in understanding the various costs and expenses of investing in common shares of the Funds. The information in the table reflects the fees and expenses for each Fund’s fiscal year ended October 31, 2011, as adjusted as described in footnote 1 below, and the pro-forma expenses for the 12 months ended October 31, 2011, for the combined fund. The figures in the Example are not necessarily indicative of past or future expenses, and actual expenses may be greater or less than those shown. The Funds’ actual rates of return may be greater or less than the hypothetical 5% annual return shown in the Example.

Comparative Fee Table(1)

|  | Acquiring Fund |  |  | Premier Opportunity |  |  | Premium Opportunity |  |  | Combined Fund Pro Forma(2) |
Annual Expenses (as a percentage of net assets applicable to common shares) |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Management Fees |  |  | 0.95 | % |  |  | 0.96 | % |  |  | 0.94 | % |  |  | 0.92 | %
Interest and Related Expenses from Inverse Floaters and Preferred Shares(3) |  |  | 1.15 | % |  |  | 0.59 | % |  |  | 0.77 | % |  |  | 0.84 | %
Other Expenses |  |  | 0.11 | % |  |  | 0.10 | % |  |  | 0.09 | % |  |  | 0.09 | %
Total Annual Expenses |  |  | 2.21 | % |  |  | 1.65 | % |  |  | 1.80 | % |  |  | 1.85 | %

(1) | “Annual Expenses (as a percentage of net assets applicable to common shares)” are based on the expenses of the Acquiring Fund and Acquired Funds for the twelve (12) months ended October 31, 2011, subject to the following adjustments. For the Acquiring Fund and Premier Opportunity, “Interest and Related Expenses from Inverse Floaters and Preferred Shares” reflects annualized interest and related expenses for preferred shares that were outstanding for less than the 12-month period. For the Acquiring Fund and Premier Opportunity, “Other Expenses” excludes expenses incurred during the 12-month period for auction fees and/or dividend disbursing agent fees associated with auction rate preferred shares that are no longer outstanding. For the Acquiring Fund, fee and expense reimbursements that expired during the 12-month period are not reflected. It is important for you to understand that a decline in a Fund’s average net assets applicable to common shares during the current fiscal year due to recent market volatility or other factors could cause each Fund’s expense ratios for that Fund’s current fiscal year to be higher than the expense information presented.

(2) | The Combined Fund Pro Forma figures assume the consummation of the Reorganizations on October 31, 2011, and reflect average net assets applicable to common shares for the Acquiring Fund and the Acquired Funds for the 12-month period ended October 31, 2011. Combined Fund Pro Forma expenses do not include the expenses to be borne by the Funds in connection with the Reorganizations, which are estimated to be $320,000 (0.10%) for the Acquiring Fund, $45,000 (0.02%) for Premier Opportunity and $540,000 (0.11%) for Premium Opportunity.

(3) | “Interest and Related Expenses from Inverse Floaters and Preferred Shares” arises because accounting rules require the Funds to treat interest paid by trusts issuing certain inverse floating rate investments held by the Funds as having been paid (indirectly) by the Funds. Because the Funds also recognize corresponding amounts of interest income (also indirectly), each Fund’s common share net asset value, net investment income and total return are not affected by this accounting treatment. The actual “Interest and Related Expenses from Inverse Floaters and Preferred Shares” incurred in the future may be higher or lower. Dividends paid on each Fund’s currently outstanding preferred shares are recognized as interest expense for financial reporting purposes.

Example: The following examples illustrate the expenses that a common shareholder would pay on a $1,000 investment that is held for the time periods provided in the table. The examples assume that all dividends and other distributions are reinvested and that Total Annual Expenses remain the same. The examples also assume a 5% annual return. The examples should not be considered a representation of future expenses. Actual expenses may be greater or lesser than those shown.

(1) | Prior to January 2, 2012, each Fund had a policy of investing at least 80% of its Managed Assets in municipal securities covered by insurance guaranteeing the timely payment of principal and interest. Each Fund also had a policy of investing in securities rated at least investment grade. Performance may have differed had the current policies of the Fund been in place.

Average Annual Total Return on Net Asset Value is the combination of changes in common share net asset value, reinvested dividend income at net asset value and reinvested capital gains distributions at net asset value, if any. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending net asset value. The actual reinvestment price for the last dividend declared in the period may often be based on the Fund’s market price (and not its net asset value), and therefore may be different from the price used in the calculation. Average Annual Total Return on Market Value is the combination of changes in the market price per share and the effect of reinvested dividend income and reinvested capital gains distributions, if any, at the average price paid per share at the time of reinvestment. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last dividend declared in the period may take place over several days, and in some instances it may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation. Total returns are not annualized. Past performance information is not necessarily indicative of future results.

B. | RISK FACTORS

Investment in the Acquiring Fund may not be appropriate for all investors. The Acquiring Fund is not intended to be a complete investment program and, due to the uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objectives. Investors should consider their long-term investment goals and financial needs when making an investment decision with respect to the Acquiring Fund. An investment in the Acquiring Fund is intended to be a long-term investment, and you should not view the Fund as a trading vehicle. Your shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions, if applicable.

Because the Funds have similar investment strategies, the principal risks of each Fund are similar. The principal risks of investing in the Acquiring Fund and the Acquired Funds are described below. The risks and special considerations listed below should be considered by shareholders of each Fund in their evaluation of the Reorganizations.

Investment and Market Risk. An investment in the Funds’ shares is subject to investment risk, including the possible loss of the entire amount that you invest. Your investment in common shares represents an indirect investment in the municipal securities owned by a Fund, which generally trade in

10

the over-the-counter markets. Your shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions, if applicable. In addition, the ability of municipalities to collect revenue and service their obligations could be materially and adversely affected by an economic downturn or prolonged recession.

Current Economic Conditions—Credit Crisis Liquidity and Volatility Risk. Markets for credit instruments, including municipal securities, have experienced periods of extreme illiquidity and volatility since the latter half of 2007. General market uncertainty and consequent repricing risk have led to market imbalances of sellers and buyers, which in turn have resulted in significant valuation uncertainties in a variety of debt securities, including municipal securities. These conditions resulted, and in many cases continue to result, in greater volatility, less liquidity, widening credit spreads and a lack of price transparency, with many debt securities remaining illiquid and of uncertain value. These market conditions may make valuation of some of the Funds’ municipal securities uncertain and/or result in sudden and significant valuation increases or declines in its holdings. A significant decline in the value of your Fund’s portfolio would likely result in a significant decline in the value of the Fund’s common shares. In addition, illiquidity and volatility in the credit markets may directly and adversely affect distributions on the common shares and preferred shares. This volatility may also impact the liquidity of inverse floating rate securities in your Fund’s portfolio. See “Risk Factors—Inverse Floating Rate Securities Risk.”

In response to the current national economic condition, governmental cost burdens may be reallocated among federal, state and local governments. In addition, laws enacted in the future by Congress or state legislatures or referenda could extend the time for payment of principal and/or interest, or impose other constraints on enforcement of such obligations, or on the ability of municipalities to levy taxes. Issuers of municipal securities have and may seek protection under the bankruptcy laws. See “Risk Factors—Municipal Securities Market Risk.”

Market Discount from Net Asset Value. Shares of closed-end investment companies may fluctuate and during certain periods trade at prices lower than net asset value. The Funds cannot predict whether their common shares will trade at, above or below net asset value. This characteristic is a risk separate and distinct from the risk that a Fund’s net asset value could decrease as a result of investment activities. Investors bear a risk of loss to the extent that the price at which they sell their shares is lower in relation to the Fund’s net asset value than at the time of purchase, assuming a stable net asset value. The common shares are designed primarily for long-term investors, and you should not view a Fund as a vehicle for trading purposes.

Credit and Below-Investment Grade Risk. Credit risk is the risk that one or more municipal securities in a Fund’s portfolio will decline in price, or the issuer thereof will fail to pay interest or principal when due, because the issuer experiences a decline in its financial status. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates. If a downgrade occurs, the Adviser will consider what action, including the sale of the security, is in the best interests of a Fund. Municipal securities of below-investment-grade quality are regarded as having predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal when due, and they are more susceptible to default or decline in market value due to adverse economic and business developments than investment-grade municipal securities. Also, to the extent that the rating assigned to a municipal security in a Fund’s portfolio is downgraded by any NRSRO, the market price and liquidity of such security may be adversely affected. The market values for municipal securities of below-investment-grade quality tend to be volatile, and these

11

securities are less liquid than investment-grade municipal securities. For these reasons, an investment in a Fund, compared with a portfolio consisting solely of investment-grade securities, may experience the following:

| — |  | increased price sensitivity resulting from a deteriorating economic environment and changing interest rates;

| — |  | greater risk of loss due to default or declining credit quality;

| — |  | adverse issuer-specific events that are more likely to render the issuer unable to make interest and/or principal payments; and

| — |  | the possibility that a negative perception of the below-investment-grade market develops, resulting in the price and liquidity of below-investment-grade securities becoming depressed, and this negative perception could last for a significant period of time.

Municipal Securities Market Risk. Investing in the municipal securities market involves certain risks. The municipal securities market is one in which dealer firms make markets in bonds on a principal basis using their proprietary capital, and during the recent market turmoil these firms’ capital became severely constrained. As a result, some firms were unwilling to commit their capital to purchase and to serve as a dealer for municipal securities. The amount of public information available about the municipal securities in each Fund’s portfolio is generally less than that for corporate equities or bonds, and the Funds’ investment performance may therefore be more dependent on the Adviser’s analytical abilities than if the Funds were to invest in stocks or taxable bonds. As noted above, the secondary market for municipal securities also tends to be less well developed or liquid than many other securities markets, which may adversely affect a Fund’s ability to sell its municipal securities at attractive prices or at prices approximating those at which each Fund currently values them. Municipal securities may contain redemption provisions, which may allow the securities to be called or redeemed prior to their stated maturity, potentially resulting in the distribution of principal and a reduction in subsequent interest distributions.

The ability of municipal issuers to make timely payments of interest and principal may be diminished during general economic downturns and as governmental cost burdens are reallocated among federal, state and local governments. If the current national economic recession continues, the ability of municipalities to collect revenue and service their obligations could be materially and adversely affected. The taxing power of any government entity may be limited by provisions of state constitutions or laws, and an entity’s credit will depend on many factors, including the entity’s tax base, the extent to which the entity relies on federal or state aid, and other factors which are beyond the entity’s control. In addition, laws enacted in the future by Congress or state legislatures or referenda could extend the time for payment of principal and/or interest, or impose other constraints on enforcement of such obligations, or on the ability of municipalities to levy taxes. Issuers of municipal securities might seek protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, a Fund could experience delays in collecting principal and interest and a Fund may not, in all circumstances, be able to collect all principal and interest to which it is entitled. To enforce its rights in the event of a default in the payment of interest or repayment of principal, or both, a Fund may take possession of and manage the assets securing the issuer’s obligations on such securities, which may increase a Fund’s operating expenses. Any income derived from a Fund’s ownership or operation of such assets may not be tax-exempt and may not be of the type that would allow a Fund to continue to qualify as a regulated investment company.

12

Revenue bonds issued by state or local agencies to finance the development of low-income, multi-family housing involve special risks in addition to those associated with municipal securities generally, including that the underlying properties may not generate sufficient income to pay expenses and interest costs. These bonds are generally non-recourse against the property owner, may be junior to the rights of others with an interest in the properties, may pay interest that changes based in part on the financial performance of the property, may be prepayable without penalty and may be used to finance the construction of housing developments which, until completed and rented, do not generate income to pay interest. Additionally, unusually high rates of default on the underlying mortgage loans may reduce revenues available for the payment of principal or interest on such mortgage revenue bonds.

Interest Rate Risk. Generally, when market interest rates rise, bond prices fall, and vice versa. Interest rate risk is the risk that the municipal securities in a Fund’s portfolio will decline in value because of increases in market interest rates. In typical market interest rate environments, the prices of longer-term municipal securities generally fluctuate more than prices of shorter-term municipal securities as interest rates change.

Inverse Floating Rate Securities Risk. Each Fund can have substantial exposure to municipal inverse floating rate securities, which are securities whose interest rates bear an inverse relationship to the interest rate on another security or the value of an index, and which represent a leveraged investment in underlying municipal bonds. Typically, an inverse floating rate security represents a residual beneficial interest in a special purpose trust into which a third-party sponsor has deposited municipal bonds, and which issues floating rate securities to short-term investors and inverse floating rate securities to long-term investors such as the Funds. Income on typical inverse floating rate securities will decrease when short-term interest rates increase and increase when short-term interest rates decrease, so investments in inverse floating rate securities offer the opportunity for higher income than the underlying bond, but will subject a Fund to the risk of lower or even no income if short-term interest rates rise sufficiently. Inverse floating rate securities represent a leveraged investment in the underlying municipal bond deposited. The value of an inverse floating rate security will increase or decrease in value by a multiple of the increase or decrease of the market value of its underlying bond due to changes in market interest rates or the bond’s creditworthiness. That multiple is dependent on the ratio of the special purpose trust’s floating rate securities to its inverse floating rate securities, and can exceed three times for more “highly leveraged” trusts. Thus, when investing in an inverse floating rate security rather than directly in the underlying bond, a Fund will experience a greater increase in its common net asset value if the underlying municipal bond increases in value, but will also experience a correspondingly larger decline in its common net asset value if the underlying bond declines in value, which will make a Fund’s net asset value more volatile.

Each Fund may invest in inverse floating rate securities issued by special purpose trusts whose sponsors have recourse to the Fund pursuant to a separate shortfall and forbearance agreement. Such an agreement would require a Fund to reimburse the third-party sponsor of the trust, upon termination of the trust issuing the inverse floater, for the difference between the liquidation value of the bonds held in the trust and the principal amount due to the holders of floating rate securities issued by the trust. A Fund will enter into such a recourse agreement (i) when the liquidity provider with respect to the floating rate securities issued by the special purpose trust requires such a recourse agreement because the level of leverage in the special purpose trust exceeds the level that the liquidity provider is willing to support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing the special purpose trust in the event that the municipal obligation held in the trust has declined in value. In an instance where a Fund has entered such a recourse agreement, the Fund may

13

suffer a loss that exceeds the amount of its original investment in the inverse floating rate securities; such loss could be as great as that original investment amount plus the face amount of the floating rate securities issued by the trust.

Inverse floating rate securities have varying degrees of liquidity or illiquidity (liquidity being the ability to raise cash by selling the investment in a timely manner at an attractive price) based in large part upon the liquidity of the underlying bonds deposited in a special purpose trust. The leverage attributable to such inverse floating rate securities may be “called away” on relatively short notice and therefore may be less permanent than more traditional forms of leverage. In such circumstances, a Fund may be required to sell securities at inopportune times or prices. Each Fund may be required to sell its inverse floating rate securities or its underlying municipal bonds at less than favorable prices, or liquidate other Fund portfolio holdings in certain circumstances, including, but not limited to, the following:

| — |  | If a Fund has a need for cash and the bonds in a special purpose trust are not actively trading due to adverse market conditions;

| — |  | If special purpose trust sponsors (as a collective group or individually) experience financial hardship and consequently seek to terminate their respective outstanding trusts; and

| — |  | If the value of an underlying bond declines significantly (to a level below the notional value of the floating rate securities issued by the trust) and if additional collateral has not been posted by the Fund.

Leverage Risk. Leverage risk is the risk associated with borrowings, the issuance of preferred shares or the use of inverse floating rate securities to leverage the common shares. There can be no assurance that a Fund’s leveraging strategy will be successful. Through the use of financial leverage, the Funds seek to enhance potential common share earnings over time by borrowing or issuing preferred shares at short-term municipal rates and investing at long-term municipal rates which are typically, though not always, higher. The types of leverage used by the Funds may pay fixed rates of interest or dividends or may fluctuate with short-term yields. The benefits from leverage will be reduced (increased) to the extent that the difference narrows (widens) between the net earnings on a Fund’s portfolio securities and its cost of leverage. If short-term rates rise and a Fund’s leverage costs fluctuate, a Fund’s cost of leverage could exceed the rate of return on longer-term bonds held by the Fund that were acquired during periods of lower interest rates, reducing returns to common shareholders. A Fund’s cost of leverage includes both the interest rate paid on its borrowings or dividends on preferred shares as well as any ongoing fees and expenses associated with those borrowings or preferred shares. The Funds also bear the costs of borrowing facilities, issuing its shares and refinancing such leverage. To the extent that the Funds issue preferred shares with relatively short terms to redemption (e.g., MTP Shares or VMTP Shares), refinancing risk will increase. To the extent that Funds issue preferred shares with a liquidity provider feature (e.g., VRDP Shares), the Fund is subject to refinancing risk if the liquidity provider acquires VRDP Shares pursuant to its purchase obligation and holds them for six months of unsuccessful remarketings, triggering a mandatory redemption. Refinancing risk is the risk that the Fund is unable to replace existing leverage at all or on favorable terms. If the Fund is unable to replace its leverage upon a term redemption date or other mandatory redemption of MTP Shares or VMTP Shares or upon a mandatory redemption of VRDP Shares, it may be forced to reduce leverage and sell portfolio securities when it otherwise would not do

14

so. If the Fund is unable to replace existing leverage on comparable terms, its costs of leverage will increase. Accordingly, there is no assurance that the use of leverage may result in a higher yield or return to common shareholders.

A Fund’s use of financial leverage also creates incremental common share net asset value risk because the full impact of price changes in the Fund’s investment portfolio, including assets attributable to leverage, is borne by common shareholders. This can lead to a greater increase in net asset values in rising markets than if a Fund were not leveraged, but it also can result in a greater decrease in net asset values in declining markets. A Fund’s use of financial leverage similarly can magnify the impact of changing market conditions on common share market prices. Each Fund is required to maintain certain regulatory and rating agency asset coverage requirements in connection with its outstanding preferred shares, in order to be able to maintain the ability to declare and pay common share distributions and to maintain the rating of its preferred shares. In order to maintain required asset coverage levels, a Fund may be required to alter the composition of its investment portfolio or take other actions, such as redeeming preferred shares with the proceeds from portfolio transactions, at what might be an inopportune time in the market. Such actions could reduce the net earnings or returns to common shareholders over time.

Each Fund may invest in the securities of other investment companies, which may themselves be leveraged and therefore present similar risks to those described above.

The amount of fees paid to the Adviser for investment advisory services will be higher when a Fund uses financial leverage because the advisory fees are calculated based on the Fund’s Managed Assets.

Tax Risk. To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, among other things, a Fund must derive in each taxable year at least 90% of its gross income from certain prescribed sources. If for any taxable year a Fund does not qualify as a regulated investment company, all of its taxable income (including its net capital gain) would be subject to federal income tax at regular corporate rates without any deduction for distributions to shareholders, and all distributions from the Fund (including underlying distributions attributable to tax exempt interest income) would be taxable to shareholders as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits.

The value of a Fund’s investments and its net asset value may be adversely affected by changes in tax rates and policies. Because interest income from municipal securities held by a Fund is normally not subject to regular federal income tax, the attractiveness of municipal securities in relation to other investment alternatives is affected by changes in federal income tax rates or changes in the tax-exempt status of interest income from municipal securities. Any proposed or actual changes in such rates or exempt status, therefore, can significantly affect the demand for and supply, liquidity and marketability of municipal securities. This could in turn affect a Fund’s net asset value and ability to acquire and dispose of municipal securities at desirable yield and price levels. Additionally, the Funds are not suitable investments for individual retirement accounts, for other tax-exempt or tax-deferred accounts or for investors who are not sensitive to the federal income tax consequences of their investments.

The Acquiring Fund’s policy of generally investing in bonds that are exempt from the federal AMT applicable to individuals may prevent the Fund from investing in certain kinds of bonds and thereby limit the Fund’s ability to optimally diversify its portfolio.

On September 12, 2011, President Obama submitted to Congress the American Jobs Act of 2011. If enacted in its proposed form, this Act generally would limit the exclusion from gross income

15

of tax-exempt interest (which includes exempt-interest dividends received from a Fund) for individuals whose adjusted gross income for federal income tax purposes exceeds certain thresholds for taxable years beginning on or after January 1, 2013 in order to provide a tax benefit not greater than 28% of such interest. Such proposal could affect the value of the municipal bonds owned by a Fund. The likelihood of the Act being enacted in the form introduced or in some other form cannot be predicted. Shareholders should consult their own tax advisers regarding the potential consequences of this Act on their investment in a Fund.

Taxability Risk. Each Fund will invest in municipal securities in reliance at the time of purchase on an opinion of bond counsel to the issuer that the interest paid on those securities will be excludable from gross income for regular federal income tax purposes, and the Adviser will not independently verify that opinion. Subsequent to a Fund’s acquisition of such a municipal security, however, the security may be determined to pay, or to have paid, taxable income. As a result, the treatment of dividends previously paid or to be paid by a Fund as “exempt-interest dividends” could be adversely affected, subjecting the Fund’s shareholders to increased federal income tax liabilities. In certain circumstances, a Fund will make payments to holders of preferred shares to offset the tax effects of a taxable distribution.

Under highly unusual circumstances, the Internal Revenue Service (the “IRS”) may determine that a municipal bond issued as tax-exempt should in fact be taxable. If a Fund held such a bond, it might have to distribute taxable ordinary income dividends or reclassify as taxable income amounts previously distributed as exempt-interest dividends. In addition, future legislation may change the tax treatment of municipal bond interest.

For federal income tax purposes, distributions of ordinary taxable income (including any net short-term capital gain) will be taxable to shareholders as ordinary income (and will not be eligible for favorable taxation as “qualified dividend income”), and capital gain dividends will be taxed at long-term capital gain rates.

Borrowing Risk. Each Fund may borrow money for the repurchase of its shares or for temporary or emergency purposes, such as for the payment of dividends or the settlement of portfolio transactions. Borrowing may exaggerate changes in the net asset value of a Fund’s common shares and may affect a Fund’s net income. When a Fund borrows money, it must pay interest and other fees, which will reduce the Fund’s returns if such costs exceed the returns on the portfolio securities purchased or retained with such borrowings. Any such borrowings are intended to be temporary. However, under certain market conditions, including periods of low demand or decreased liquidity in the municipal bond market, such borrowings might be outstanding for longer periods of time.

Inflation Risk. Inflation risk is the risk that the value of assets or income from investment will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the dividends paid to preferred shareholders may decline.

Special Risks Related to Certain Municipal Obligations. Each Fund may invest in municipal leases and certificates of participation in such leases. Municipal leases and certificates of participation involve special risks not normally associated with general obligations or revenue bonds. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the

16

issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of “non-appropriation” clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body on a yearly or other periodic basis. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event the governmental issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and may result in a delay in recovering or the failure to fully recover a Fund’s original investment. In the event of non-appropriation, the issuer would be in default and taking ownership of the assets may be a remedy available to a Fund, although each Fund does not anticipate that such a remedy would normally be pursued. To the extent that a Fund invests in unrated municipal leases or participates in such leases, the credit quality rating and risk of cancellation of such unrated leases will be monitored on an ongoing basis. Certificates of participation, which represent interests in unmanaged pools of municipal leases or installment contracts, involve the same risks as the underlying municipal leases. In addition, a Fund may be dependent upon the municipal authority issuing the certificates of participation to exercise remedies with respect to the underlying securities. Certificates of participation also entail a risk of default or bankruptcy, both of the issuer of the municipal lease and also the municipal agency issuing the certificate of participation.

Derivatives Risk. Each Fund’s use of derivatives involves risks different from, and possibly greater than, the risks associated with investing directly in the investments underlying the derivatives. Whether a Fund’s use of derivatives is successful will depend on, among other things, if the Adviser correctly forecasts market values, interest rates and other applicable factors. If the Adviser incorrectly forecasts these and other factors, the investment performance of a Fund will be unfavorably affected. In addition, the derivatives market is largely unregulated. It is possible that developments in the derivatives market could adversely affect a Fund’s ability to successfully use derivative instruments.

Each Fund may enter into debt-related derivatives instruments including credit default swap contracts and interest rate swaps. Like most derivative instruments, the use of swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. In addition, the use of swaps requires an understanding by the Adviser of not only of the referenced asset, rate or index, but also of the swap itself. Because they are two-party contracts and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid. Moreover, a Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. It is possible that developments in the swaps market, including potential government regulation, could adversely affect a Fund’s ability to terminate existing swap agreements or to realize amounts to be received under such agreements. See “—Counterparty Risk” and “—Hedging Risk” and the Reorganization SAI.

Hedging Risk. Each Fund’s use of derivatives or other transactions to reduce risk involves costs and will be subject to the Adviser’s ability to predict correctly changes in the relationships of such hedge instruments to the Fund’s portfolio holdings or other factors. No assurance can be given that the Adviser’s judgment in this respect will be correct. In addition, no assurance can be given that a Fund will enter into hedging or other transactions at times or under circumstances in which it may be advisable to do so.

17

Other Investment Companies Risk. Each Fund may invest in the securities of other investment companies. Such securities may be leveraged. As a result, a Fund may be indirectly exposed to leverage through an investment in such securities. Utilization of leverage is a speculative investment technique and involves certain risks. An investment in securities of other investment companies that are leveraged may expose a Fund to higher volatility in the market value of such securities and the possibility that a Fund’s long-term returns on such securities will be diminished.

Deflation Risk. Deflation risk is the risk that prices throughout the economy decline over time, which may have an adverse effect on the market valuation of companies, their assets and revenues. In addition, deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of a Fund’s portfolio.

Counterparty Risk. Changes in the credit quality of the companies that serve as a Fund’s counterparties with respect to derivatives, insured municipal securities or other transactions supported by another party’s credit will affect the value of those instruments. Certain entities that have served as counterparties in the markets for these transactions have recently incurred significant financial hardships including bankruptcy and losses as a result of exposure to sub-prime mortgages and other lower quality credit investments that have experienced recent defaults or otherwise suffered extreme credit deterioration. As a result, such hardships have reduced these entities’ capital and called into question their continued ability to perform their obligations under such transactions. By using such derivatives or other transactions, a Fund assumes the risk that its counterparties could experience similar financial hardships. In the event of insolvency of a counterparty, a Fund may sustain losses or be unable to liquidate a derivatives position.

Illiquid Securities Risk. Each Fund may invest in municipal securities and other instruments that, at the time of investment, are illiquid. Illiquid securities are securities that are not readily marketable and may include restricted securities, which are securities that may not be resold unless they have been registered under the Securities Act of 1933, as amended, or can be sold in a private transaction pursuant to an exemption from registration. Illiquid securities involve the risk that the securities will not be able to be sold at the time desired by a Fund or at prices approximating the value at which the Fund is carrying the securities on its books.

Market Disruption Risk. Certain events have a disruptive effect on the securities markets, such as terrorist attacks (including the terrorist attacks in the United States on September 11, 2001), war and other geopolitical events. A Fund cannot predict the effects of similar events in the future on the U.S. economy.

Income Risk. A Fund’s income is based primarily on the interest it earns from its investments, which can vary widely over the short-term and long-term. If interest rates drop, a Fund’s income available over time to make dividend payments could drop as well if the Fund purchases securities with lower interest coupons.

Call Risk or Prepayment Risk. During periods of declining interest rates or for other purposes, issuers may exercise their option to prepay principal earlier than scheduled, forcing a Fund to reinvest in lower-yielding securities. This is known as call or prepayment risk.

Reinvestment Risk. Reinvestment risk is the risk that income from a Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called bonds at market interest rates that are below the Fund’s portfolio’s current earnings rate.

18

Reliance on Investment Adviser. Each Fund is dependent upon services and resources provided by the Adviser, and therefore the Adviser’s parent, Nuveen Investments. Nuveen Investments, through its own business or the financial support of its affiliates, may not be able to generate sufficient cash flow from operations or ensure that future borrowings will be available in an amount sufficient to enable it to pay its indebtedness or to fund its other liquidity needs. For additional information on the Adviser and Nuveen Investments, see “Proposal No. 1—Comparison of the Acquiring Fund and Each Acquired Fund—Investment Adviser” and “Investment Adviser and Sub-Adviser” in the Reorganization SAI.

Certain Affiliations. Certain broker-dealers may be considered to be affiliated persons of the Funds, the Adviser and/or Nuveen Investments. Absent an exemption from the Securities and Exchange Commission or other regulatory relief, a Fund generally is precluded from effecting certain principal transactions with affiliated brokers, and its ability to purchase securities being underwritten by an affiliated broker or a syndicate including an affiliated broker, or to utilize affiliated brokers for agency transactions, is subject to restrictions. This could limit a Fund’s ability to engage in securities transactions and take advantage of market opportunities.

Anti-Takeover Provisions. Each Fund’s organizational documents include provisions that could limit the ability of other entities or persons to acquire control of the Fund or convert the Fund to open-end status.

C. | INFORMATION ABOUT THE REORGANIZATIONS

General

The Board of Nuveen’s municipal closed-end funds has approved a series of mergers of municipal closed-end funds, including the Reorganizations with respect to the Acquiring Fund and each Acquired Fund. As noted above, the Acquiring Fund and each Acquired Fund have similar investment objectives and policies and substantially similar portfolio compositions. With respect to the proposed Reorganizations, it is intended that the combination of the Funds will enhance the secondary trading market for common shares of the Funds and will result in lower operating expenses per common share (excluding the cost of leverage) as a result of the increased size of the combined fund. The closing of each Reorganization is contingent upon the closing of all of the Reorganizations. Each Fund must obtain all requisite shareholder approvals as well as certain consents, confirmations and/or waivers from various third parties, including liquidity providers and rating agencies with respect to preferred shares. Because the closing of the Reorganizations is contingent on both Acquired Funds and the Acquiring Fund obtaining the requisite shareholder approvals and satisfying (or obtaining the waiver of) their other closing conditions, it is possible that your Fund’s Reorganization will not occur, even if shareholders of your Fund approve the Reorganization and your Fund satisfies all of its closing conditions. If the Reorganizations are not consummated, the Board of each Fund may take such actions as it deems in the best interests of its Fund, including conducting additional solicitations with respect to the proposals or continuing to operate the Fund as a stand-alone funds.

Terms of the Reorganizations

General. With respect to the Reorganizations, the Agreement and Plan of Reorganization by and among each Acquired Fund and the Acquiring Fund (the “Agreement”), in the form attached as Appendix A, provides for: (i) the Acquiring Fund’s acquisition of substantially all of the assets of each

19

Acquired Fund in exchange for newly issued common shares of the Acquiring Fund, par value $0.01 per share and newly issued VRDP Shares of the Acquiring Fund, with a par value of $0.01 per share and a liquidation preference of $100,000 per share, and the Acquiring Fund’s assumption of substantially all of the liabilities of each Acquired Fund; and (ii) the distribution of the Acquiring Fund common shares and Acquiring Fund VRDP Shares received by each Acquired Fund to its common and preferred shareholders, respectively, as part of the liquidation, dissolution and termination of each Acquired Fund in accordance with applicable law. No fractional Acquiring Fund common shares will be issued to an Acquired Fund’s shareholders in connection with the Reorganizations and, in lieu of such fractional shares, an Acquired Fund’s common shareholders will receive cash in an amount equal to the value received for such shares in the open market, which may be higher or lower than net asset value. Preferred shareholders of each Acquired Fund will receive the same number of Acquiring Fund VRDP Shares having substantially similar terms as the outstanding preferred shares of the Acquired Fund held by such preferred shareholders immediately prior to the Reorganization. The aggregate liquidation preference of the Acquiring Fund preferred shares received in each Reorganization will equal the aggregate liquidation preference of the corresponding Acquired Fund preferred shares held immediately prior to the Reorganization. Preferred shares issued by the Acquiring Fund in connection with the Reorganizations will have equal priority with each other and with the Acquiring Fund’s other outstanding preferred shares as to the payment of dividends and the distribution of assets in the event of the Acquiring Fund’s liquidation. In addition, the preferred shares of the Acquiring Fund, including the Acquiring Fund preferred shares to be issued in the Reorganizations, will be senior in priority to the Acquiring Fund’s common shares, as to the payment of dividends and distribution of assets in the event of the Acquiring Fund’s liquidation.

As a result of the Reorganizations, the assets of the Acquiring Fund and each Acquired Fund would be combined, and the shareholders of each Acquired Fund would become shareholders of the Acquiring Fund. The closing date is expected to be the close of business on or about , 20 or such other date as the parties may agree (the “Closing Date”). Following the Reorganizations, each Acquired Fund would terminate its registration as an investment company under the 1940 Act. The Acquiring Fund will continue to operate after the Reorganizations as a registered closed-end management investment company with the investment objectives and policies described in this Joint Proxy Statement/Prospectus.

The aggregate net asset value of Acquiring Fund common shares received by each Acquired Fund in a Reorganization will equal, as of the Valuation Time (as such term is defined on page 21), the aggregate net asset value of Acquired Fund common shares held by shareholders of such Acquired Fund. See “Proposal No. 1—Information About the Reorganizations—Description of Common Shares Issued by the Acquiring Fund” for a description of the rights of Acquiring Fund common shareholders. No fractional Acquiring Fund common shares, however, will be issued in connection with the Reorganizations. The Acquiring Fund’s transfer agent will aggregate all fractional Acquiring Fund common shares that may be due to Acquired Fund shareholders as of the Closing Date and will sell the resulting whole shares for the account of holders of all such fractional interests at a value that may be higher or lower than net asset value, and each such holder will be entitled to a pro rata share of the proceeds from such sale. With respect to the aggregation and sale of fractional common shares, the Acquiring Fund’s transfer agent will act directly on behalf of the shareholders entitled to receive fractional shares and will accumulate fractional shares, sell the shares and distribute the cash proceeds net of brokerage commissions, if any, directly to shareholders entitled to receive the fractional shares (without interest and subject to withholding taxes). For federal income tax purposes, shareholders will be treated as if they received fractional share interests and then sold such interests for cash. The holding period and the aggregate tax basis of fractional share interests deemed received by a

20

shareholder will be the same as the holding period and aggregate tax basis of the Acquired Fund common shares previously held by the shareholder and exchanged therefor, provided the Acquired Fund shares exchanged therefor were held as capital assets. As a result of the Reorganizations, common shareholders of the Funds will hold reduced percentages of ownership in the larger combined entity than they held in the Acquiring Fund or Acquired Funds individually.

Following the Reorganizations, each preferred shareholder of an Acquired Fund would own the same number of Acquiring Fund VRDP Shares as the VRDP Shares of the Acquired Fund held by such shareholder immediately prior to the Closing Date, with substantially similar terms, as of the time of the closing of the Reorganizations, to the Acquired Fund preferred shares for which they were exchanged. As a result of the Reorganizations, preferred shareholders of the Funds would hold reduced voting percentages of preferred shares for matters to be voted on by all preferred shareholders as a single class or by common and preferred shareholders voting together than they held in the Acquiring Fund or Acquired Fund individually.

Valuation of Assets and Liabilities. If the Reorganizations are approved and the other closing conditions are satisfied or waived, the value of the net assets of an Acquired Fund will be the value of its assets, less its liabilities, computed as of the close of regular trading on the NYSE on the business day immediately prior to the Closing Date (such time and date being hereinafter called the “Valuation Time”). The value of an Acquired Fund’s assets shall be determined by using the valuation procedures of the Nuveen closed-end funds adopted by the Board or such other valuation procedures as shall be mutually agreed upon by the parties. The value of an Acquired Fund’s net assets will be calculated net of the liquidation preference (including accumulated and unpaid dividends) of all outstanding Acquired Fund preferred shares.

Distributions. Undistributed net investment income represents net earnings from a Fund’s investment portfolio that over time have not been distributed to shareholders. Under the terms of the Agreement, each Acquired Fund that has undistributed net investment income on undistributed net capital gains is required to declare a distribution, which, together with all previous dividends have the effect of distributing to its shareholders all undistributed net investment income and undistributed realized net capital gains (after reduction by any available capital loss carryforwards) for all taxable periods ending on or before the Closing Date. The Acquiring Fund is not subject to a similar distribution requirement; however, it is anticipated that the Acquiring Fund will declare a distribution prior to the Closing Date which will result in the distribution of a portion of its undistributed net investment income. Consequently, Acquired Fund shareholders effectively will purchase a pro rata portion of the Acquiring Fund’s remaining undistributed net investment income and undistributed realized net capital gains, if any, which may be more or less than the Acquired Fund’s undistributed net investment income and undistributed realized net capital gains per share immediately preceding the distributions described above, if any. As a result, the Acquiring Fund’s existing shareholders will experience a corresponding reduction in their respective portion of undistributed net investment income and undistributed realized net capital gains per share, if any, such that the Acquiring Fund’s undistributed net investment income and undistributed realized net capital gains per share immediately following the Reorganizations is expected to be less than the Acquiring Fund’s undistributed net investment income and undistributed realized net capital gains per share immediately preceding the Reorganizations, if any.

Amendments. Under the terms of the Agreement, the Agreement may be amended, modified, or supplemented in such manner as may be mutually agreed upon in writing by each Fund as specifically authorized by each Fund’s Board; provided, however, that following the meeting of the

21

shareholders of the Funds called by each Fund, no such amendment, modification or supplement may have the effect of changing the provisions for determining the number of Acquiring Fund shares to be issued to the Acquired Funds’ shareholders under the Agreement to the detriment of such shareholders without their further approval.

Conditions. Under the terms of the Agreement, the closing of the Reorganizations is conditioned upon (a) the requisite approval by the shareholders of each Fund of the proposals in this Joint Proxy Statement/Prospectus, (b) the Funds’ receipt of an opinion substantially to the effect that each Reorganization will qualify as a reorganization under the Code (See “—Material Federal Income Tax Consequences of the Reorganizations”), (c) the absence of legal proceedings challenging the Reorganizations and (d) the Funds’ receipt of certain customary certificates and legal opinions. Additionally, in order for the Reorganizations to occur, each Fund must obtain certain consents, confirmations and/or waivers from various third parties, including liquidity providers and rating agencies with respect to outstanding preferred shares.

Termination. The Agreement may be terminated by the mutual agreement of the parties and such termination may be effected by each Fund’s Chief Administrative Officer or a Vice President without further action by the Board. In addition, any Fund may at its option terminate the Agreement at or before the Closing Date due to (a) a breach by any other party of any representation, warranty, or agreement contained herein to be performed at or before the Closing Date, if not cured within 30 days; (b) a condition precedent to the obligations of the terminating party that has not been met and it reasonably appears it will not or cannot be met; or (c) a determination by its Board that the consummation of the transactions contemplated by the Agreement is not in the best interests of the Fund.

Reasons for the Reorganizations

Based on the considerations below, the Board of each Fund, including the Board Members who are not “interested persons” (as defined in the 1940 Act) of the Funds (the “Independent Board Members”), has determined that its Reorganization would be in the best interests of the Fund and that the interests of the existing shareholders of the Fund would not be diluted with respect to net asset value as a result of the Reorganization. The Boards approved the Reorganizations and recommended that shareholders of the respective Funds approve the Reorganizations.

In preparation for a meeting of the Boards held on June 21, 2012 (the “Meeting”) at which the Reorganizations were considered, the Adviser provided the Boards, prior to the Meeting and in prior meetings, with information regarding the proposed Reorganizations, including the rationale therefor and alternatives considered to the Reorganizations. Prior to approving the Reorganizations, the Independent Board Members reviewed the foregoing information with their independent legal counsel and with management, reviewed with independent legal counsel applicable law and their duties in considering such matters, and met with independent legal counsel in a private session without management present. The Boards considered a number of principal factors presented at the time of the Meeting or prior meetings in reaching their determinations, including the following:

| — |  | the compatibility of the Funds’ investment objectives, policies and related risks;

| — |  | consistency of portfolio management;

| — |  | improved economies of scale and the potential for lower operating expenses (excluding the costs of leverage);

22

| — |  | the potential for improved secondary market trading with respect to the common shares;

| — |  | the anticipated tax-free nature of the Reorganizations;

| — |  | the expected costs of the Reorganizations;

| — |  | the terms of the Reorganizations and whether the Reorganizations would dilute the interests of shareholders of the Funds;

| — |  | the effect of the Reorganizations on shareholder rights; and

| — |  | any potential benefits of the Reorganizations to the Adviser and its affiliates as a result of the Reorganizations.

In addition, at a meeting held on September 19, 2012, the Board of the Acquiring Fund approved the Acquiring Fund VRDP Shares to be issued in connection with the Reorganizations with terms that differ in certain respects from those of the VRDP Shares of the corresponding Acquired Funds.

Compatibility of Investment Objectives, Policies and Related Risks. Based on the information presented, the Boards noted that the investment objectives, policies and risks of the Funds are similar. The Boards noted that each Fund is a diversified fund that invests primarily in municipal securities and other related investments the income from which is exempt from regular federal income tax and, with respect to the Acquiring Fund, from the federal AMT. Each Fund also emphasizes investments in investment grade municipal securities. The Boards considered that the portfolio composition of each Fund is substantially similar and considered the impact of the applicable Reorganization on each Fund’s portfolio, including any shifts in sector allocations, credit ratings, duration, yield and leverage costs. The Boards also recognized that each Fund utilizes leverage. Because the Funds have similar investment strategies, the principal risks of each Fund are also similar. However, the Acquiring Fund’s policy of generally investing in bonds that are exempt from the federal AMT applicable to individuals may prevent the Acquiring Fund from investing in certain kinds of bonds.

Consistency of Portfolio Management. The Boards noted that each Fund has the same investment adviser and sub-adviser and that the portfolio manager for the Acquiring Fund and Premier Opportunity would continue to manage the Acquiring Fund upon completion of the Reorganizations. Through the Reorganizations, the Boards recognized that shareholders will remain invested in a closed-end management investment company that will have greater net assets and benefits from potential economies of scale; the same investment adviser and sub-adviser; and similar investment objectives and investment strategies.

Improved Economies of Scale and Potential for Lower Operating Expenses (Excluding the Costs of Leverage). The Boards considered the fees and expense ratios of each of the Funds (including estimated expenses of the Acquiring Fund following the Reorganizations). As a result of the greater economies of scale from the larger asset size of the Acquiring Fund after the Reorganizations, the Boards noted that it was expected that the effective management fee rate (as a percentage of average daily Managed Assets) and net operating expenses per common share (excluding the costs of leverage) of the combined fund would be lower than that of the Acquiring Fund and the Acquired Funds prior to the Reorganizations. It is anticipated that the Funds will benefit from the larger asset size as fixed costs are shared over a larger asset base. In addition, as each Fund utilizes leverage, the Boards considered the differences in the costs of leverage among the Funds and the impact of the

23

Reorganizations on such costs. In this connection, the Boards noted the Adviser’s position that the greater asset size of the combined fund may provide greater flexibility in managing the structure and costs of leverage over time. Further, although the anticipated total annual operating expenses per common share of the combined fund (including the costs of leverage) are expected to be higher for each Acquired Fund due to the increased levels of leverage and higher proportion of fixed-rate leverage in the combined fund, such leverage may produce higher returns for common shares over time to the extent that the returns obtained from investing leverage proceeds exceed the costs of leverage.

Potential for Improved Secondary Market Trading with Respect to the Common Shares. While it is not possible to predict trading levels at the time the Reorganizations close, the Boards noted that the Reorganizations are being proposed, in part, to seek to enhance the secondary trading market for the common shares of the Funds. The Boards considered that the potential for higher common share net earnings and enhanced total returns over time may increase investor interest in the combined fund which would result in increased market liquidity. The Acquiring Fund’s greater share volume may result in increased market liquidity after the Reorganizations, which may lead to narrower bid-ask spreads and smaller trade-to-trade price movements. In addition, Acquired Fund common shareholders may experience improved secondary market trading after the Reorganizations because the Acquiring Fund’s policy of investing primarily in municipal securities exempt from the federal AMT applicable to individuals, which is not currently in place with respect to the Acquired Funds, may appeal to a broader group of investors.

Anticipated Tax-Free Reorganizations. The Reorganizations will be structured with the intention that they qualify as tax-free reorganizations for federal income tax purposes, and the Funds will obtain an opinion of counsel substantially to this effect (based on certain factual representations and certain customary assumptions).

Expected Costs of the Reorganizations. The Boards considered the terms and conditions of the Agreement, including the estimated costs associated with the Reorganizations and the allocation of such costs among the Acquiring Fund and each Acquired Fund. The Boards noted, however, that, assuming the Reorganizations are consummated, the Adviser anticipated that the projected costs of each Reorganization may be recovered over time for the common shareholders and that preferred shareholders are not expected to bear any costs of the Reorganizations.

Terms of the Reorganizations and Impact on Shareholders. The terms of the Reorganizations are intended to avoid dilution of the interests with respect to net asset value of the existing shareholders of the Funds. In this regard, the Boards considered that each holder of common shares of an Acquired Fund would own common shares of the Acquiring Fund (taking into account any fractional shares to which the shareholder would be entitled) equal to the aggregate per share net asset value of that shareholder’s Acquired Fund common shares as of the Valuation Time. No fractional common shares of the Acquiring Fund, however, will be issued to shareholders in connection with the Reorganizations and, in lieu of such fractional shares, an Acquired Fund’s common shareholders will receive cash.

With respect to preferred shareholders of the Acquired Funds, preferred shareholders of each Acquired Fund will receive the same number of Acquiring Fund VRDP Shares having substantially similar terms as the outstanding preferred shares of the Acquired Fund held by such preferred shareholders immediately prior to the Reorganizations. The aggregate liquidation preference of the Acquiring Fund preferred shares received in each Reorganization will equal the aggregate liquidation preference of the corresponding Acquired Fund preferred shares held immediately prior to the Reorganization.

24

Effect on Shareholder Rights. The Boards considered that Premier Opportunity is organized as a Minnesota corporation and that the Acquiring Fund and Premium Opportunity are each organized as Massachusetts business trusts. In this regard, the Boards noted that, unlike a Massachusetts business trust, many aspects of the corporate governance of a Minnesota corporation are prescribed by state statutory law. In addition, the Boards are aware that the structure of the Boards of the Massachusetts Funds differs from that of the Minnesota Fund.

Potential Benefits to Nuveen Fund Advisors and Affiliates. The Boards recognized that the Reorganizations may result in some benefits and economies for the Adviser and its affiliates. These may include, for example, a reduction in the level of operational expenses incurred for administrative, compliance and portfolio management services as a result of the elimination of the Acquired Funds as separate Funds in the Nuveen complex.

Conclusion. Each Board, including the Independent Board Members, approved the Reorganization involving its Fund, concluding that such Reorganization is in the best interests of the Fund and that the interests of existing shareholders of the Fund will not be diluted with respect to net asset value as a result of the Reorganization.

Capitalization

The following table sets forth the unaudited capitalization of the Funds as of April 30, 2012, and the pro-forma combined capitalization of the combined fund as if the Reorganizations had occurred on that date. The table reflects a pro forma exchange ratio of approximately 1.0107 common shares of the Acquiring Fund issued for each common share of Premier Opportunity and a pro forma exchange ratio of approximately 0.9371 common shares of the Acquiring Fund issued for each common share of Premium Opportunity. If the Reorganizations are consummated, the actual exchange ratio may vary.

These numbers are based on the net asset value of the Acquiring Fund and Acquired Funds as of April 30, 2012, adjusted for estimated Reorganization costs, the effect of the required sale of securities and distributions, if any.

(3) | Includes the impact of estimated total Reorganization costs of $905,000, which will be borne by the common shareholders of the Acquiring Fund, Premier Opportunity and Premium Opportunity in the amounts of $320,000, $45,000 and $540,000, respectively.

(4) | Figures assume Premier Opportunity and Premium Opportunity make net investment income distributions of $3,661,389 and $5,943,679, respectively.

Expenses Associated with the Reorganizations

In evaluating the Reorganizations, management of the Funds estimated the amount of expenses the Funds would incur to be approximately $905,000, which includes additional stock exchange listing fees, SEC registration fees, legal and accounting fees, proxy solicitation and distribution costs and other related administrative or operational costs. The expenses of the Reorganizations (whether or not consummated) will be allocated among the Funds ratably based on the relative expected benefits of the Reorganizations comprised of forecasted cost savings and distribution increases, if any, to each Fund during the first year following the Reorganizations. Reorganization expenses have been or will be accrued as expenses of each Fund prior to the Valuation Time. These estimated expenses will be borne by the Acquiring Fund, Premier Opportunity and Premium Opportunity in the amounts of $320,000, $45,000 and $540,000, respectively. Preferred shareholders of the Funds are not expected to bear any costs of the Reorganizations.

Additional solicitation may be made by letter or telephone by officers or employees of Nuveen Investments or the Adviser, or by dealers and their representatives. The Funds have engaged Computershare Fund Services to assist in the solicitation of proxies at an estimated aggregate cost of $1,500 per Fund plus reasonable expenses, which is included in the estimate above.

Dissenting Shareholders’ Rights of Appraisal

Under the charter documents of the Acquiring Fund and Premium Opportunity, shareholders of the Acquiring Fund and Premium Opportunity do not have dissenters’ rights of appraisal with respect to each Fund’s Reorganization.

26

Under Minnesota law, shareholders of Premier Opportunity generally are entitled to assert dissenters’ rights in connection with a reorganization and obtain payment of the “fair value” of their shares, provided that they comply with the requirements of Minnesota law. However, because the common shares of Premier Opportunity are listed and trade on an exchange, under Minnesota law, only the holders of preferred shares of Premier Opportunity, and not the holders of common shares, will be entitled to assert dissenters’ rights.

Material Federal Income Tax Consequences of the Reorganizations

As a condition to each Fund’s obligation to consummate the Reorganizations, each Fund will receive a tax opinion from Vedder Price P.C. (which opinion will be based on certain factual representations and certain customary assumptions) with respect to its Reorganization substantially to the effect that, on the basis of the existing provisions of the Code, current administrative rules and court decisions, for federal income tax purposes:

| 1. | The transfer of substantially all of the assets of the Acquired Fund to the Acquiring Fund in exchange solely for Acquiring Fund shares and the assumption by the Acquiring Fund of substantially all of the liabilities of the Acquired Fund, followed by the distribution to the Acquired Fund shareholders of all the Acquiring Fund shares received by the Acquired Fund in complete liquidation of the Acquired Fund will constitute a “reorganization” within the meaning of Section 368(a) of the Code, and the Acquiring Fund and the Acquired Fund will each be a “party to a reorganization,” within the meaning of Section 368(b) of the Code, with respect to such Reorganization.

| 2. | No gain or loss will be recognized by the Acquiring Fund upon the receipt of substantially all of the assets of the Acquired Fund solely in exchange for Acquiring Fund shares and the assumption by the Acquiring Fund of substantially all of the liabilities of the Acquired Fund.

| 3. | No gain or loss will be recognized by the Acquired Fund upon the transfer of substantially all of the Acquired Fund’s assets to the Acquiring Fund solely in exchange for Acquiring Fund shares and the assumption by the Acquiring Fund of substantially all of the liabilities of the Acquired Fund or upon the distribution (whether actual or constructive) of all such Acquiring Fund shares to the Acquired Fund shareholders solely in exchange for such shareholders’ shares of the Acquired Fund in complete liquidation of the Acquired Fund.

| 4. | No gain or loss will be recognized by the Acquired Fund shareholders upon the exchange of their Acquired Fund shares solely for Acquiring Fund shares in the Reorganization, except with respect to any cash received in lieu of a fractional Acquiring Fund common share.

| 5. | The aggregate basis of the Acquiring Fund shares received by each Acquired Fund shareholder pursuant to the Reorganization (including any fractional Acquiring Fund common share to which a shareholder would be entitled) will be the same as the aggregate basis of the Acquired Fund shares exchanged therefor by such shareholder. The holding period of the Acquiring Fund shares received by each Acquired Fund shareholder (including any fractional Acquiring Fund common share to which a shareholder would be entitled) will include the period during which the Acquired Fund shares exchanged

27

| therefor were held by such shareholder, provided such Acquired Fund shares are held as capital assets at the time of the Reorganization.

| 6. | The basis of the Acquired Fund’s assets acquired by the Acquiring Fund will be the same as the basis of such assets to the Acquired Fund immediately before the Reorganization. The holding period of the assets of the Acquired Fund in the hands of the Acquiring Fund will include the period during which those assets were held by the Acquired Fund.

In addition, Sidley Austin LLP, as special tax counsel to the Acquiring Fund, will deliver an opinion to the Acquiring Fund, subject to certain representations, assumptions and conditions, substantially to the effect that the Acquiring Fund VRDP Shares received in the Reorganizations by the holders of VRDP Shares of the Acquired Funds will qualify as equity in the Acquiring Fund for federal income tax purposes.

No opinion will be expressed as to (1) the federal income tax consequences of payments to preferred shareholders who elect dissenters’ rights, (2) the effect of a Reorganization on (A) an Acquired Fund, the Acquiring Fund or any Acquired Fund shareholder with respect to any asset as to which any unrealized gain or loss is required to be recognized under federal income tax principles (i) at the end of a taxable year (or on the termination thereof) or (ii) upon the transfer of such asset regardless of whether such transfer would otherwise be a non-taxable transaction under the Code, or (B) an Acquired Fund, the Acquiring Fund or any Acquired Fund shareholder with respect to any stock held in a passive foreign investment company as defined in Section 1297(a) of the Code or (3) any other federal tax issues (except those set forth above) and all state, local or foreign tax issues of any kind.

If an Acquired Fund shareholder receives cash in lieu of a fractional Acquiring Fund share, the shareholder will be treated as having received the fractional Acquiring Fund share pursuant to the Reorganization and then as having sold that fractional Acquiring Fund share for cash. As a result, each such Acquired Fund shareholder generally will recognize gain or loss equal to the difference between the amount of cash received and the basis in the fractional Acquiring Fund share to which the shareholder is entitled. This gain or loss generally will be a capital gain or loss and generally will be long-term capital gain or loss if, as of the effective time of the Reorganization, the holding period for the shares (including the holding period of Acquired Fund shares surrendered therefor if such Acquired Fund Shares were held as capital assets at the time of the Reorganization) is more than one year. The deductibility of capital losses is subject to limitations. Any cash received in lieu of a fractional share may be subject to backup withholding taxes.

Prior to the Valuation Time, each Acquired Fund will declare a distribution to its common shareholders, which together with all previous distributions to preferred and common shareholders, will have the effect of distributing to shareholders all its net investment income and realized net capital gains (after reduction by any available capital loss carryforwards), if any, through the date of its Reorganization. To the extent distributions are attributable to ordinary taxable income or capital gains, the distribution will be taxable to shareholders for federal income tax purposes. Each Fund designates distributions to common and preferred shareholders as consisting of particular types of income (such as exempt interest, ordinary income and capital gain) based on each class’ proportionate share of the total distributions paid by the Fund during the year. Additional distributions may be made if necessary. All dividends and distributions will be paid in cash unless a shareholder has made an election to reinvest dividends and distributions in additional shares under the Acquired Fund’s dividend reinvestment plan. Dividends and distributions are treated the same for federal income tax purposes whether received in cash or additional shares.

28

After the Reorganizations, the combined fund’s ability to use the Acquired Funds’ or the Acquiring Fund’s pre-Reorganization capital losses may be limited under certain federal income tax rules applicable to reorganizations of this type. Therefore, in certain circumstances, shareholders may pay federal income taxes sooner, or pay more federal income taxes, than they would have had the Reorganizations not occurred. The effect of these potential limitations, however, will depend on a number of factors including the amount of the losses, the amount of gains to be offset, the exact timing of the Reorganizations and the amount of unrealized capital gains in the Funds at the time of the Reorganizations. As of April 30, 2012, the Funds had capital loss carryforwards as follows:

|  | Acquiring Fund |  |  | Premier Opportunity |  |  | Premium Opportunity |
Capital loss carryforwards |  | $ | 5,915,863 |  |  | $ | 1,240,117 |  |  | $ | 3,731,586 |

If not applied, the capital loss carryforwards will expire as follows:

|  | Acquiring Fund |  |  | Premier Opportunity |  |  | Premium Opportunity |
Expiration Date: |  |  |  |  |  |  |  |  |  |  |  |
October 31, 2013 |  | $ | 3,824,358 |  |  | $ | — |  |  | $ | — |
October 31, 2015 |  | $ | 174,026 |  |  | $ | — |  |  | $ | — |
October 31, 2016 |  | $ | 1,917,479 |  |  | $ | 1,240,117 |  |  | $ | 3,274,999 |
October 31, 2017 |  | $ | — |  |  | $ | — |  |  | $ | 456,587 |

For net capital losses arising in taxable years beginning after December 22, 2010 (“post-enactment losses”), a Fund will generally be able to carryforward such capital losses indefinitely. A Fund’s net capital losses from taxable years beginning on or prior to December 22, 2010, however, will remain subject to their current expiration dates and can be used only after the post-enactment losses.

In addition, the shareholders of an Acquired Fund will receive a proportionate share of any taxable income and gains realized by the Acquiring Fund and not distributed to its shareholders prior to the Reorganizations when such income and gains are eventually distributed by the Acquiring Fund. As a result, shareholders of an Acquired Fund may receive a greater amount of taxable distributions than they would have had the Reorganizations not occurred.

This description of the federal income tax consequences of the Reorganizations is made without regard to the particular facts and circumstances of any shareholder. Shareholders are urged to consult their own tax advisers as to the specific consequences to them of the Reorganizations, including the applicability and effect of state, local, non-U.S. and other tax laws.

The foregoing is intended to be only a summary of the principal federal income tax consequences of the Reorganizations and should not be considered to be tax advice. There can be no assurance that the Internal Revenue Service will concur on all or any of the issues discussed above. Shareholders are urged to consult their own tax advisers regarding the federal, state and local tax consequences with respect to the foregoing matters and any other considerations which may be applicable to them.

Votes Required

Each Reorganization is required to be approved by the affirmative vote of the holders of a majority (more than 50%) of the outstanding shares of the Acquired Fund’s common shares and

29

preferred shares entitled to vote on the matter, voting as a single class, and by the affirmative vote of the holders of a majority (more than 50%) of the Acquired Fund’s outstanding preferred shares entitled to vote on the matter, voting as a separate class. Each Reorganization also is required to be approved by the affirmative vote of the holders of a majority (more than 50%) of the Acquiring Fund’s outstanding preferred shares entitled to vote on the matter, voting as a separate class. Preferred shareholders (other than holders of MTP Shares and VMTP Shares of the Acquiring Fund who are being solicited through this Joint Proxy Statement/Prospectus) are being solicited separately on the foregoing proposals through a separate proxy statement and not through this Joint Proxy Statement/Prospectus. In addition, the Acquiring Fund’s common shareholders entitled to vote on the matter, voting separately, and the Acquiring Fund’s common and preferred shareholders entitled to vote on the matter, voting together as a single class, are being asked to approve the issuance of additional common shares of the Acquiring Fund in connection with the Reorganizations. See “Proposal No. 2—Approval of Issuance of Additional Common Shares of Acquiring Fund” for a description of the votes required for such share issuance.

Abstentions and broker non-votes will have the same effect as a vote against the approval of the Reorganizations and the issuance of additional common shares of the Acquiring Fund. Broker non-votes are shares held by brokers or nominees for which the brokers or nominees have executed proxies as to which (i) the broker or nominee does not have discretionary voting power and (ii) the broker or nominee has not received instructions from the beneficial owner or other person who is entitled to instruct how the shares will be voted.

Preferred shareholders of each Fund are separately being asked to approve the Agreement as a “plan of reorganization” under the 1940 Act. Section 18(a)(2)(D) of the 1940 Act provides that the terms of preferred shares issued by a registered closed-end management investment company must contain provisions requiring approval by the vote of a majority of such shares, voting as a class, of any plan of reorganization adversely affecting such shares. The 1940 Act makes no distinction between a plan of reorganization that has an adverse effect as opposed to a materially adverse effect. While the respective Boards do not believe that the Funds’ preferred shareholders would be materially adversely affected by the Reorganizations, it is possible that there may be insignificant adverse effects (such as where the asset coverage with respect to the Acquiring Fund VRDP Shares issued pursuant to a Reorganization is slightly more or less than the asset coverage with respect to the shares of Acquired Fund VRDP Shares for which they are exchanged). Each Fund is seeking approval of the Agreement by the holders of that Fund’s preferred shares.

The closing of each Reorganization is contingent upon the closing of both Reorganizations. In order for the Reorganizations to occur, each Fund must obtain the requisite shareholder approvals as well as certain consents, confirmations and/or waivers from various third parties, including liquidity providers and rating agencies with respect to preferred shares. Because the closing of the Reorganizations is contingent on all of the Acquired Funds and the Acquiring Fund satisfying (or obtaining the waiver of) their respective closing conditions, if one or more of the other Funds do not obtain their requisite shareholder approvals or satisfy their closing conditions, it is possible that your Fund’s Reorganization will not occur, even if shareholders of your Fund approve the Reorganization and your Fund satisfies all of its closing conditions. VMTP Shares and VRDP Shares are issued on a private placement basis to one or a small number of institutional holders. To the extent that one or more preferred shareholders of a Fund owns, holds or controls, individually or in the aggregate, all or a significant portion of a Fund’s outstanding preferred shares, one or more shareholder approvals required for a Reorganization may turn on the exercise of voting rights by such particular shareholder(s) and its or their determination as to the favorable view of such proposal(s) with respect to

30

its or their interests. The Funds exercise no influence or control over the determinations of such shareholders with respect to the proposals; there is no guarantee that such shareholders will approve the proposals over which they may exercise effective disposition power. If the requisite shareholder approvals are not obtained, each Fund’s Board may take such actions as it deems in the best interests of such Fund, including conducting additional solicitations with respect to the proposals or continuing to operate the Fund as a stand-alone fund.

Description of Common Shares to be Issued by the Acquiring Fund; Comparison to Acquired Funds

General

As a general matter, the common shares of the Acquiring Fund and each Acquired Fund have equal voting rights and equal rights with respect to the payment of dividends and the distribution of assets upon liquidation with respect to their respective Fund and have no preemptive, conversion or exchange rights or rights to cumulative voting. Furthermore, the provisions set forth in the Acquiring Fund’s declaration of trust are substantially similar to the provisions of each Acquired Fund’s declaration of trust or articles of incorporation, as applicable, and each contain, among other things, similar super-majority voting provisions, as described under “Additional Information about the Funds—Certain Provisions in the Acquiring Fund’s Declaration of Trust”. The full text of each Fund’s declaration of trust or articles of incorporation, as applicable, is on file with the SEC and may be obtained as described on page v.

The Acquiring Fund’s declaration of trust authorizes an unlimited number of common shares, par value $0.01 per share. If the Reorganizations are consummated, the Acquiring Fund will issue additional common shares on the Closing Date to the common shareholders of each Acquired Fund based on the relative per share net asset value of the Acquiring Fund and the net asset values of the assets of such Acquired Fund (net of the liquidation preference and accumulated and unpaid dividends of any Acquired Fund preferred shares) that are transferred in the Reorganization, in each case as of the Valuation Time.

The terms of the Acquiring Fund common shares to be issued pursuant to the Reorganizations will be identical to the terms of the Acquiring Fund common shares that are then outstanding. Acquiring Fund common shares have equal rights with respect to the payment of dividends and the distribution of assets upon liquidation. The Acquiring Fund common shares, when issued, will be fully paid and non-assessable and have no preemptive, conversion or exchange rights or rights to cumulative voting. See also “Comparison of Massachusetts Business Trusts and Minnesota Corporations.”

Distributions

As a general matter, each Fund has a monthly distribution policy and each Fund seeks to maintain a stable level of distributions. Each Fund’s present policy, which may be changed by its Board, is to make regular monthly cash distributions to holders of its common shares at a level rate (stated in terms of a fixed cents per common share dividend rate) that reflects the past and projected performance of the Fund.

The Acquiring Fund’s ability to maintain a level dividend rate will depend on a number of factors, including the rate at which dividends are payable on the preferred shares. The net income of the Acquiring Fund generally consists of all interest income accrued on portfolio assets less all

31

expenses of the Fund. Expenses of the Acquiring Fund are accrued each day. Over time, all the net investment income of the Acquiring Fund will be distributed. At least annually, the Acquiring Fund also intends to effectively distribute net capital gain and ordinary taxable income, if any, after paying any accrued dividends or making any liquidation payments to preferred shareholders. Although it does not now intend to do so, the Board may change the Acquiring Fund’s dividend policy and the amount or timing of the distributions based on a number of factors, including the amount of the Fund’s undistributed net investment income and historical and projected investment income and the amount of the expenses and dividend rates on the outstanding preferred shares.

As explained more fully below, at least annually, the Acquiring Fund may elect to retain rather than distribute all or a portion of any net capital gain (which is the excess of net long-term capital gain over net short-term capital loss) otherwise allocable to common shareholders and pay federal income tax on the retained gain. As provided under federal income tax law, common shareholders of record as of the end of the Acquiring Fund’s taxable year will include their share of the retained net capital gain in their income for the year as a long-term capital gain (regardless of their holding period in the common shares), and will be entitled to an income tax credit or refund for the federal income tax deemed paid on their behalf by the Acquiring Fund. See “Federal Income Tax Matters Associated with Investment in the Funds” under “Additional Information About the Funds” below and “Tax Matters” in the Reorganization SAI.

So long as preferred shares are outstanding, the Acquiring Fund may not declare a dividend or distribution to common shareholders (other than a dividend in common shares of the Fund) or purchase its common shares unless all accumulated dividends on preferred shares have been paid, and unless asset coverage (as defined in the 1940 Act) with respect to preferred shares at the time of the declaration of such dividend or distribution or at the time of such purchase would be at least 200% after giving effect to the dividend or distribution or purchase price.

Dividend Reinvestment Plan

Generally, the terms of the Acquiring Fund’s dividend reinvestment plan (the “Plan”) are identical to the terms of each Acquired Fund’s dividend reinvestment plan. Under the Acquiring Fund’s Plan, you may elect to have all dividends, including any capital gain distributions, on your common shares automatically reinvested by State Street Bank and Trust Company (the “Plan Agent”) in additional common shares under the Plan. You may elect to participate in the Plan by completing the Dividend Reinvestment Plan Application Form. If you do not participate, you will receive all distributions in cash paid by check mailed directly to you by State Street Bank and Trust Company as dividend paying agent.

If you decide to participate in the Plan of the Acquiring Fund, the number of common shares you will receive will be determined as follows:

(1) If common shares are trading at or above net asset value at the time of valuation, the Acquiring Fund will issue new shares at the then current market price; or

(2) If common shares are trading below net asset value at the time of valuation, the Plan Agent will receive the dividend or distribution in cash and will purchase common shares in the open market, on the exchange on which the common shares are listed, for the participants’ accounts. It is possible that the market price for the common shares may increase before the Plan Agent has completed its purchases. Therefore, the average purchase price per share paid by the Plan Agent may exceed the market price at the time of valuation, resulting in the purchase of fewer shares than if the dividend or distribution had been paid in common shares issued by the Acquiring Fund. The Plan

32

Agent will use all dividends and distributions received in cash to purchase common shares in the open market within 30 days of the valuation date. Interest will not be paid on any uninvested cash payments.

If the Plan Agent begins purchasing Acquiring Fund shares on the open market while shares are trading below net asset value, but the Fund’s shares subsequently trade at or above their net asset value before the Plan Agent is able to complete its purchases, the Plan Agent may cease open-market purchases and may invest the uninvested portion of the distribution in newly issued Fund shares at a price equal to the greater of the shares’ net asset value or 95% of the shares’ market value.

You may withdraw from the Plan at any time by giving written notice to the Plan Agent. If you withdraw or the Plan is terminated, you will receive a cash payment for any fraction of a share in your account. If you wish, the Plan Agent will sell your shares and send you the proceeds, minus brokerage commissions and a $2.50 service fee.

The Plan Agent maintains all shareholders’ accounts in the Plan and gives written confirmation of all transactions in the accounts, including information you may need for tax records. Common shares in your account will be held by the Plan Agent in non-certificated form. Any proxy you receive will include all common shares you have received under the Plan.

There is no brokerage charge for reinvestment of your dividends or distributions in common shares. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases.

Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due upon receiving dividends and distributions.

The Acquiring Fund reserves the right to amend or terminate the Plan if in the judgment of the Board of the Acquiring Fund the change is warranted. There is no direct service charge to participants in the Plan; however, the Acquiring Fund reserves the right to amend the Plan to include a service charge payable by the participants.

Box 43071, Providence, Rhode Island 02940-3071, (800) 257-8787.

On October 26, 2012, the closing sale prices of the Acquiring Fund, Premier Opportunity and Premium Opportunity common shares were $15.89, $15.86 and $14.87, respectively. These prices represent a premium to net asset value of the Acquiring Fund of 2.58% and a discount to net asset value of Premier Opportunity and Premium Opportunity of 1.31% and 0.40%, respectively.

Common shares of each Fund have historically traded at both a premium and discount to net asset value. It is not possible to state whether Acquiring Fund common shares will trade at a premium or discount to net asset value following the Reorganizations, or what the extent of any such premium or discount might be.

Description of VRDP Shares to be Issued by the Acquiring Fund

The terms of the VRDP Shares of the Acquiring Fund to be issued pursuant to each Reorganization will be substantially similar, as of the time of the closing of the Reorganizations, to the outstanding VRDP Shares of the Acquired Fund for which they are exchanged. The aggregate liquidation preference of each series of Acquiring Fund VRDP Shares received in each Reorganization will equal the aggregate liquidation preference of the corresponding Acquired Fund VRDP Shares held immediately prior to the Reorganization.

34

The outstanding VRDP Shares of each Acquired Fund had a 30-year final mandatory redemption date as of their original issue date, subject to earlier redemption or repurchase by the Fund, and pay an adjustable dividend rate set weekly by the remarketing agent. VRDP Shares to be issued by the Acquiring Fund will have the same final mandatory redemption dates as the Acquired Fund shares exchanged therefor. VRDP shareholders will have the right to give notice on any business day to tender the securities for remarketing in seven days. VRDP Shares will also be subject to a mandatory tender for remarketing upon the occurrence of certain events, such as non-payment of dividends by a Fund, among others. Should a remarketing be unsuccessful, the dividend rate will reset to a maximum rate as defined in the governing documents of the VRDP Shares.

VRDP Shares of each series will have the benefit of an unconditional demand feature pursuant to a purchase agreement provided by a bank acting as liquidity provider to ensure full and timely repayment of the liquidation preference amount plus any accumulated and unpaid dividends to holders upon the occurrence of certain events. The agreement requires the liquidity provider to purchase from holders all VRDP Shares of the applicable series tendered for sale that were not successfully remarketed. The liquidity provider also must purchase all outstanding VRDP Shares of the applicable series prior to termination of the purchase agreement, including by reason of the failure of the liquidity provider to maintain certain short-term ratings, if the Acquiring Fund has not obtained an alternate purchase agreement before the termination date.

The obligation of the liquidity provider to purchase VRDP Shares pursuant to the purchase agreement will run to the benefit of VRDP holders of the applicable series and will be unconditional and irrevocable, and as such the short-term ratings assigned to the VRDP Shares are directly linked to the short-term creditworthiness of the associated liquidity provider. With respect to each series of VRDP Shares, the applicable liquidity provider entered into a purchase agreement with the Acquired Fund with an initial term of 364 days to approximately fourteen months, subject to periodic extension by agreement with the Fund. With respect to each series of VRDP Shares, the applicable initial term of the purchase agreement with the liquidity provider for each series of VRDP Shares of the Acquiring Fund is expected to be no less than the remaining term of the applicable purchase agreement with respect to the corresponding Acquired Fund shares exchanged therefor.

Pursuant to the statement of preferences and a fee agreement with each liquidity provider for each series of VRDP Shares, the Acquiring Fund will have an obligation to redeem shares purchased by the liquidity provider pursuant to its obligations under the purchase agreement if the liquidity provider continues to be the beneficial owner for a period of six months and such shares cannot be successfully remarketed.

Premier Opportunity issued its VRDP Shares in a privately negotiated offering in December 2010. Premium Opportunity exchanged all of its 2,190 Series 1 VRDP Shares, issued in August 2008, for 2,190 Series 2 VRDP Shares in June 2010. Proceeds of each Fund’s initial offering were used to redeem all of each Fund’s then outstanding auction rate preferred shares. The VRDP Shares were offered to qualified institutional buyers pursuant to a private offering exempt from registration under the Securities Act of 1933.

Comparison of Massachusetts Business Trusts and Minnesota Corporations

The following description is based on relevant provisions of applicable Massachusetts law and the Minnesota Business Corporation Act (the “MBCA”) and each Fund’s operative documents. This summary does not purport to be complete and we refer you to applicable Massachusetts law, the MBCA and each Fund’s operative documents.

35

General

The Acquiring Fund and Premium Opportunity are each a Massachusetts business trust. A fund organized as a Massachusetts business trust is governed by the trust’s declaration of trust or similar instrument.

Massachusetts law allows the trustees of a business trust to set the terms of a fund’s governance in its declaration. All power and authority to manage the fund and its affairs generally reside with the trustees, and shareholder voting and other rights are limited to those provided to the shareholders in the declaration. Because Massachusetts law governing business trusts provides more flexibility compared to typical state corporate statutes, the Massachusetts business trust is a common form of organization for closed-end funds. However, some consider it less desirable than other entities because it relies on the terms of the applicable declaration and judicial interpretations rather than statutory provisions for substantive issues, such as the personal liability of shareholders and trustees, and does not provide the level of certitude that corporate laws like those of Minnesota, or newer statutory trust laws, such as those of Delaware, provide.

Premier Opportunity is a Minnesota corporation. A fund organized as a Minnesota corporation is governed both by the MBCA and the Minnesota corporation’s articles of incorporation and by-laws. For a Minnesota corporation, unlike a Massachusetts business trust, the MBCA prescribes many aspects of corporate governance.

Shareholders of a Minnesota corporation generally are shielded from personal liability for the corporation’s debts or obligations. Shareholders of a Massachusetts business trust, on the other hand, are not afforded the statutory limitation of personal liability generally afforded to shareholders of a corporation from the trust’s liabilities. Instead, the declaration of trust of a fund organized as a Massachusetts business trust typically provides that a shareholder will not be personally liable, and further provides for indemnification to the extent that a shareholder is found personally liable, for the fund’s acts or obligations. The declaration of trust for each of the Acquiring Fund and Premium Opportunity contains such provisions.

Similarly, the trustees of a Massachusetts business trust are not afforded statutory protection from personal liability for the obligations of the trust. The directors of a Minnesota corporation, on the other hand, generally are shielded from personal liability for the corporation’s acts or obligations by the MBCA. Courts in Massachusetts have, however, recognized limitations of a trustee’s personal liability in contract actions for the obligations of a trust contained in the trust’s declaration, and declarations may also provide that trustees may be indemnified out of the assets of the trust to the extent held personally liable. The declaration of trust for each of the Acquiring Fund and Premium Opportunity contains such provisions.

Massachusetts Business Trusts

The Acquiring Fund and Premium Opportunity are each governed by its declaration of trust and by-laws. Under each Fund’s declaration of trust, any determination as to what is in the interests of the Fund made by the trustees in good faith is conclusive, and in construing the provisions of the declaration of trust, there is a presumption in favor of a grant of power to the trustees. Further, each declaration of trust provides that certain determinations made in good faith by the trustees are binding upon the Fund and all shareholders, and shares are issued and sold on the condition and understanding, evidenced by the purchase of shares, that any and all such determinations shall be so binding. The

36

following is a summary of some of the key provisions of the governing documents of the Acquiring Fund and Premium Opportunity (each a “Massachusetts Fund” and together the “Massachusetts Funds”).

Shareholder Voting. The declaration of trust of each Massachusetts Fund requires a shareholder vote on a number of matters, including certain amendments to the declaration of trust, the election of trustees, the merger or reorganization of the Fund (under certain circumstances) or sales of assets in certain circumstances and matters required to be voted by the 1940 Act.

Meetings of shareholders may be called by the trustees and by the written request of shareholders owning at least 10% of the outstanding shares entitled to vote. The by-laws of each Massachusetts Fund provide that the holders of a majority of the voting power of the shares of beneficial interest of the Fund entitled to vote at a meeting shall constitute a quorum for the transaction of business. The declaration of trust of each Massachusetts Fund provides that the affirmative vote of the holders of a majority of the shares present in person or by proxy and entitled to vote at a meeting of shareholders at which a quorum is present is required to approve a matter, except in the case of the election of trustees, which only requires a plurality vote, and for events to which other voting provisions apply under the 1940 Act or the declaration of trust and by-laws, such as the super-majority voting provisions with respect to a merger, consolidation or dissolution of, or sale of substantially all of the assets by, the Fund, or its conversion to an open-end investment company in certain circumstances under the terms of the declaration of trust.

Election and Removal of Trustees. The declaration of trust of each Massachusetts Fund provides that the trustees determine the size of the Board, subject to a minimum of two and a maximum of twelve, and set and alter the terms of office of the trustees, and may make their terms of unlimited duration. Subject to the provisions of the 1940 Act, the declaration of trust also provides that vacancies on the Board may be filled by the remaining trustees. A trustee may only be removed for cause by action of at least two-thirds of the remaining trustees or by action of at least two-thirds of the outstanding shares of the class or classes that elected such trustee.

Issuance of Shares. Under the declaration of trust of each Massachusetts Fund, the trustees are permitted to issue an unlimited number of shares for such consideration and on such terms as the trustees may determine. Shareholders are not entitled to any preemptive rights or other rights to subscribe to additional shares, except as the trustees may determine. Shares are subject to such other preferences, conversion, exchange or similar rights, as the trustees may determine.

Classes. The declaration of trust of each Massachusetts Fund gives broad authority to the trustees to establish classes or series in addition to those currently established and to determine the rights and preferences, conversion rights, voting powers, restrictions, limitations, qualifications or terms or conditions of redemptions of the shares of the classes or series. The trustees are also authorized to terminate a class or series without a vote of shareholders under certain circumstances.

Amendments to Declaration of Trust. Amendments to the declaration of trust generally require the consent of shareholders owning more than 50% of shares entitled to vote, voting in the aggregate. Certain amendments may be made by the trustees without a shareholder vote, and any amendment to the voting requirements contained in the declaration of trust requires the approval of two-thirds of the outstanding common shares and preferred shares, voting in the aggregate and not by class except to the extent that applicable law or the declaration of trust may require voting by class.

37

Shareholder, Trustee and Officer Liability. The declaration of trust of each Massachusetts Fund provides that shareholders have no personal liability for the acts or obligations of the Fund and require the Fund to indemnify a shareholder from any loss or expense arising solely by reason of his or her being or having been a shareholder and not because of his or her acts or omissions or for some other reasons. In addition, the Fund will assume the defense of any claim against a shareholder for personal liability at the request of the shareholder. Similarly, the declaration of trust provides that any person who is a trustee, officer or employee of the Fund is not personally liable to any person in connection with the affairs of the Fund, other than to the Fund and its shareholders arising from bad faith, willful misfeasance, gross negligence or reckless disregard for his or her duty. The declaration of trust further provides for indemnification of such persons and advancement of the expenses of defending any such actions for which indemnification might be sought. The declaration of trust also provides that the trustees may rely in good faith on expert advice.

Derivative Actions. Massachusetts has what is commonly referred to as a “universal demand statute,” which requires that a shareholder make a written demand on the board, requesting the board members to bring an action, before the shareholder is entitled to bring or maintain a court action or claim on behalf of the entity.

Minnesota Corporations

A Minnesota corporation is governed by the MBCA, its articles of incorporation and by-laws. Some of the key provisions of the MBCA and the articles of incorporation and by-laws of Premier Opportunity (the “Minnesota Fund”) are summarized below.

Shareholder Voting. Under the MBCA, a Minnesota corporation generally cannot dissolve, amend its articles of incorporation, sell or otherwise transfer all or substantially all of its property and assets outside the ordinary course of business, or engage in a statutory share exchange, merger or consolidation unless approved by a vote of shareholders. Depending on the circumstances and the articles of incorporation of the corporation, there may be various exceptions to these votes. Shareholders of Minnesota corporations are generally entitled to one vote per share and fractional votes for fractional shares held. The Minnesota Fund’s articles of incorporation contain such provisions regarding fractional shares.

Election and Removal of Directors. Shareholders of a Minnesota corporation generally are entitled to elect and remove directors. Shareholders of the Minnesota Fund may elect directors at any meeting at which a quorum is present. The MBCA and by-laws provide that directors are elected by a plurality of votes validly cast at such election. The MBCA does not require a corporation to hold an annual meeting unless required by the articles of incorporation or by-laws. The Minnesota Fund’s by-laws state that annual meetings of shareholders are not required and that a special meeting of shareholders may be called by shareholders holding 10% or more of the shares entitled to vote on the matters to be presented at the meeting. The articles of incorporation provide that a director may be removed from office only for cause, and then by a vote of the shareholders holding 66 2/3% of the shares entitled to vote at an election of directors.

Amendments to the Articles of Incorporation. Under the MBCA, shareholders of corporations generally are entitled to vote on amendments to the articles of incorporation.

Issuance of Shares. The board of directors of a Minnesota corporation has the power to authorize the issuance of shares. If so provided in the articles of incorporation (and the articles of incorporation of each Minnesota Fund do so provide), the board of directors may authorize the

38

issuance of shares in more than one class or series, and prior to issuance of shares of each class or series, the board of directors must set the terms, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption for each class or series.

Shareholder, Director and Officer Liability. Under Minnesota law, shareholders generally are not personally liable for debts or obligations of a corporation. Minnesota law provides that a director’s personal liability to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director may be eliminated or limited in the articles of incorporation, except for a director’s breach of the duty of loyalty, for acts or omissions not in good faith or that involve an intentional or knowing violation of law, or for any transaction from which the director derived an improper personal benefit. The articles of incorporation of the Minnesota Fund provide such a limitation of director liability. Minnesota law provides that, unless prohibited by a corporation’s articles of incorporation or by-laws, a corporation must indemnify and advance expenses to its directors for acts and omissions in their official capacity, subject to certain exceptions, and the articles of incorporation of each Minnesota Fund do not prohibit such indemnification or advances. The indemnification provisions and the limitation on liability are both subject to any limitations of the 1940 Act, which generally provides that no director or officer shall be protected from liability to the corporation or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office. The provisions governing the advance of expenses are subject to applicable requirements of the 1940 Act or rules thereunder.

Preemptive Rights. Pursuant to the Minnesota Fund’s articles of incorporation, shareholders of Premier Opportunity have no preemptive rights.

Dissenters’ Right of Appraisal. Under Minnesota Law, shareholders are generally are entitled to assert dissenters’ rights in connection with certain amendments to the articles of incorporation, asset sales and reorganizations and obtain payment of the “fair value” of their shares, provided that they comply with the requirements of Minnesota law. These rights, however, are subject to certain exceptions under the MBCA, including, in the case of asset sales and reorganizations, if the shares to which the dissenters’ rights relate and the shares, if any, that a shareholder is to receive are traded on an exchange.

Derivative Actions. Under Minnesota law, applicable case law at the time of a particular derivative action will establish any requirements or limitations with respect to shareholder derivative actions.

The foregoing is only a summary of certain rights of shareholders under the governing documents of the Funds and under applicable state law, and is not a complete description of provisions contained in those sources. Shareholders should refer to the provisions of those documents and state law directly for a more thorough description.

D. | ADDITIONAL INFORMATION ABOUT THE INVESTMENT POLICIES

Comparison of the Investment Objectives and Policies of the Acquiring Fund and the Acquired Funds

General

The Funds have similar investment objectives and policies. The Acquiring Fund’s investment objectives are to provide current income exempt from regular federal income tax and the federal AMT

39

and to enhance portfolio value relative to the municipal bond market by investing in tax-exempt municipal bonds that the Fund’s Adviser believes are underrated or undervalued or that represent municipal market sectors that are undervalued. Premier Opportunity and Premium Opportunity have identical investment objectives, which are to provide current income exempt from regular federal income tax and to enhance portfolio value relative to the municipal bond market by investing in tax-exempt municipal bonds that the Adviser believes are underrated or undervalued or that represent municipal market sectors that are undervalued. Underrated municipal securities are those municipal securities whose ratings do not, in the Adviser’s or Sub-Adviser’s opinion, reflect their true value. They may be underrated because of the time that has elapsed since their last ratings, or because rating agencies have not fully taken into account positive factors, or for other reasons. Undervalued municipal securities are those securities that, in the Adviser’s or Sub-Adviser’s opinion, are worth more than their market value. They may be undervalued because there is a temporary excess of supply in that particular sector (such as hospital bonds, or bonds of a particular municipal issuer). The Adviser or Sub-Adviser may buy such a security even if the value of that security is consistent with the value of other securities in that sector. Municipal securities also may be undervalued because there has been a general decline in the market price of municipal securities for reasons that do not apply to the particular municipal securities that the Adviser or Sub-Adviser considers undervalued. The Adviser or Sub-Adviser believes that the prices of these municipal securities should ultimately reflect their true value.

Each Fund attempts to increase its portfolio value relative to the municipal bond market by prudent selection of municipal bonds regardless of the direction the market may move. There can be no assurance that a Fund’s attempt to increase its portfolio value relative to the municipal bond market will succeed. To the extent that it does succeed, however, such success would increase the amount of net capital gains or reduce the amount of net capital losses that a Fund would otherwise have realized. While this incremental increase in net realized gains due to successful value investing, if any, is expected to be modest over time, it would tend to result in the distribution, over time, of a modestly greater amount of taxable capital gains to common shareholders and preferred shareholders. See “Additional Information About the Funds—Federal Income Tax Matters Associated with Investment in the Funds.”

Each Fund’s investment objectives are fundamental policies of the Fund, and may not be changed, without the approval of the holders of a majority of the outstanding common shares and preferred shares voting as a single class, and of holders of a majority of the outstanding preferred shares voting separately as a single class. For purposes of the Funds’ objectives, policies and investment strategies, municipal bonds and municipal obligations are treated as municipal securities.

Investment Policies

The Acquiring Fund and Acquired Funds have similar investment policies. Under normal circumstances, the Acquiring Fund will invest at least 80% of its Managed Assets in portfolio securities that pay interest exempt from regular federal income tax and from the federal AMT. Under normal circumstances, each Acquired Fund will invest at least 80% of its Managed Assets in a portfolio of securities that pay interest exempt from regular federal income tax. The Acquired Funds do not have any policy regarding investments in securities subject to the federal AMT, and may have substantial holdings of securities subject to such tax.

Under normal circumstances, each Fund invests at least 80% of its Managed Assets in investment grade securities that, at the time of investment, are rated within the four highest grades (Baa

40

or BBB or better) by at least one NRSRO or are unrated but judged to be of comparable quality by the Adviser. Each Fund may invest up to 20% of its Managed Assets in municipal securities that at the time of investment are rated below investment grade or are unrated but judged to be of comparable quality by the Adviser. No more than 10% of a Fund’s Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by the Adviser.

The foregoing credit quality policy applies only at the time a security is purchased, and a Fund is not required to dispose of a security in the event that a rating agency subsequently downgrades its assessment of the credit characteristics of a particular issue. In determining whether to retain or sell such a security, the Adviser or Sub-Adviser may consider such factors as its assessment of the credit quality of the issuer of such security, the price at which such security could be sold and the rating, if any, assigned to such security by other rating agencies. See “Proposal No. 1—Additional Information About the Investment Policies—Municipal Securities” below for a general description of the economic and credit characteristics of municipal securities.

Each Fund may enter into derivative instruments to achieve its investment objectives, enhance return, hedge certain risks of its investments in fixed income securities or as a substitute for a position in the underlying asset. Such instruments include financial futures contracts, swap contracts (including credit default swaps and interest rate swaps), options on financial futures, options on swap contracts, or other derivative instruments. A Fund may not enter into a futures contract or related options or forward contracts if more than 30% of the Fund’s net assets would be represented by futures contracts or more than 5% of the Fund’s net assets would be committed to initial margin deposits and premiums on future contracts or related options.

Each Fund may invest in inverse floating rate securities. The Acquiring Fund may invest up to 15% of its net assets in inverse floating rate securities, while each Acquired Fund may invest up to 15% of its Managed Assets in inverse floating rate securities. Inverse floating rate securities represent a leveraged investment in the underlying municipal bond deposited. Inverse floating rate securities offer the opportunity for higher income than the underlying bond, but will subject a Fund to the risk of lower or even no income if short-term interest rates rise sufficiently. By investing in an inverse floating rate security rather than directly in the underlying bond, the Fund will experience a greater increase in its common share net asset value if the underlying municipal bond increases in value, but will also experience a correspondingly larger decline in its common share net asset value if the underlying bond declines in value.

Each Fund may borrow money for the repurchase of its shares or for temporary or emergency purposes, such as for the payment of dividends or the settlement of portfolio transactions. While any such borrowings exceed 5% of total assets, no additional purchases of investment securities will be made. Each Fund may also invest in securities of other open- or closed-end investment companies that invest primarily in municipal bonds of the types in which the Fund may invest directly. See “Proposal No. 1—Additional Information About the Investment Policies—Other Investment Companies.”

Each Fund is diversified for purposes of the 1940 Act. Consequently, as to 75% of its assets, a Fund may not invest more than 5% of its total assets in the securities of any single issuer, except that this limitation does not apply to securities of the U.S. Government, its agencies and instrumentalities.

41

The Acquired Funds are subject to certain fundamental policies that do not apply to, or are different from, the fundamental policies of the Acquiring Fund. In particular, unlike the Acquiring Fund, each of Premier Opportunity and Premium Opportunity may not:

| 1) | pledge, mortgage or hypothecate its assets, except that, to secure borrowings permitted by the Fund’s fundamental investment policy relating to borrowing for temporary or emergency purposes or for the repurchase of its shares, it may pledge securities having a market value at the time of pledge not exceeding 20% of the value of the Fund’s total assets;

| 2) | invest more than 10% of its total assets in repurchase agreements maturing in more than seven days; and

| 3) | purchase or retain the securities of any issuer other than the securities of the Fund if, to the Fund’s knowledge, those directors of the Fund, or those officers and directors of the Adviser, who individually own beneficially more than 1/2 of 1% of the outstanding securities of such issuer, together own beneficially more than 5% of such outstanding securities.

During temporary defensive periods and in order to keep a Fund’s cash fully invested, each Fund may invest up to 100% of its net assets in short-term investments including high quality, short-term securities that may be either tax exempt or taxable. It is the intent of each Fund to invest in taxable short-term investments only in the event that suitable tax-exempt short-term investments are not available at reasonable prices and yields. Investment in taxable short-term investments would result in a portion of your dividends being subject to regular federal income taxes.

Portfolio Investments

As used in this Joint Proxy Statement/Prospectus, the term “municipal securities” includes municipal securities with relatively short-term maturities. Some of these short-term securities may be variable or floating rate securities. Each Fund, however, emphasizes investments in municipal securities with long- or intermediate-term maturities. Each Fund buys municipal securities with different maturities and intends to maintain an average portfolio maturity of 15 to 30 years, although this may be shortened depending on market conditions. If the long-term municipal security market is unstable, a Fund may temporarily invest up to 100% of its assets in temporary investments. Temporary investments are high-quality, generally uninsured, short-term municipal securities that may either be tax-exempt or taxable. A Fund will buy taxable temporary investments only if suitable tax-exempt temporary investments are not available at reasonable prices and yields. A Fund will invest only in taxable temporary securities that are U.S. Government securities or corporate debt securities rated within the highest grade by Moody’s, S&P or Fitch, and that mature within one year from the date of purchase or carry a variable or floating rate of interest. Each Fund’s policies on securities ratings only apply when a Fund buys a security, and a Fund is not required to sell securities that have been downgraded. Each Fund also may invest in taxable temporary investments that are certificates of deposit from U.S. banks with assets of at least $1 billion, or repurchase agreements. Each Fund seeks to allocate taxable income on temporary investments, if any, proportionately between common shares and preferred shares, based on the percentage of total dividends distributed to each class for that year.

42

Municipal Securities

General. The Funds may invest in various municipal securities, including municipal bonds and notes and other securities issued to finance and refinance public projects, and other related securities that provide for the payment of income that is exempt from regular federal income tax.

States, local governments and municipalities issue municipal securities to raise money for public purposes such as building public facilities, refinancing outstanding obligations, and financing internal operating expenses. Municipal securities are generally either general obligation bonds, which are backed by the full faith and credit of the issuer and may be repaid from any revenue source, or revenue bonds, which may be repaid only from the revenues of a specific facility or source. The Funds also may buy municipal securities that represent interests in lease obligations. These securities carry special risks because the issuer may not be required to appropriate money annually to make payments under the lease. To reduce this risk, the Funds will only buy these securities where the issuer has a strong incentive to continue making appropriations until the municipal security matures. The Funds do not have any limits on investing in lease obligations that do not contain a “non-appropriation” clause. Each Fund may invest no more than 10% of its net assets in municipal securities issued by U.S. possessions or territories, which pay interest exempt from regular federal income tax.

The Funds may buy municipal securities that pay a variable or floating rate of interest that changes with changes in specified market rates or indices, such as a bank prime rate or a tax-exempt money market index.

Yields on municipal securities depend on many factors, including the condition of the general money market and the municipal security market, the size of a particular offering, and the maturity and rating of a particular municipal security. Moody’s, S&P’s and Fitch’s ratings represent their opinions of the quality of a particular municipal security, but these ratings are general and are not absolute quality standards. Therefore, municipal securities with the same maturity, coupon, and rating may have different yields, while municipal securities with the same maturity and coupon and different ratings may have the same yield. The market value of municipal securities will vary with changes in interest rates and in the ability of their issuers to make interest and principal payments.

Obligations of municipal security issuers are subject to bankruptcy, insolvency, and other laws affecting the rights and remedies of creditors. These obligations also may be subject to future federal or state laws or referenda that extend the time to payment of interest and/or principal, or that constrain the enforcement of these obligations or the power of municipalities to levy taxes. Legislation or other conditions may materially affect the power of a municipal security issuer to pay interest and/or principal when due.

Municipal Leases and Certificates of Participation. Each Fund may purchase municipal securities that represent lease obligations and certificates of participation in such leases. These carry special risks because the issuer of the securities may not be obligated to appropriate money annually to make payments under the lease. A municipal lease is an obligation in the form of a lease or installment purchase that is issued by a state or local government to acquire equipment and facilities. Income from such obligations generally is exempt from state and local taxes in the state of issuance. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the

43

issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of “non-appropriation” clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body on a yearly or other periodic basis. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event the issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment or facilities. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and result in a delay in recovering, or the failure to recover fully, a Fund’s original investment. To the extent that the Funds invest in unrated municipal leases or participates in such leases, the credit quality rating and risk of cancellation of such unrated leases will be monitored on an ongoing basis. In order to reduce this risk, the Funds purchase only municipal securities representing lease obligations where the Adviser believes the issuer has a strong incentive to continue making appropriations until maturity.

A certificate of participation represents an undivided interest in an unmanaged pool of municipal leases, an installment purchase agreement or other instruments. The certificates are typically issued by a municipal agency, a trust or other entity that has received an assignment of the payments to be made by the state or political subdivision under such leases or installment purchase agreements. Such certificates provide the Funds with the right to a pro rata undivided interest in the underlying municipal securities. In addition, such participations generally provide the Funds with the right to demand payment, on not more than seven days’ notice, of all or any part of the Funds’ participation interest in the underlying municipal securities, plus accrued interest.

Municipal Notes. Municipal securities in the form of notes generally are used to provide for short-term capital needs, in anticipation of an issuer’s receipt of other revenues or financing, and typically have maturities of up to three years. Such instruments may include tax anticipation notes, revenue anticipation notes, bond anticipation notes, tax and revenue anticipation notes and construction loan notes. Tax anticipation notes are issued to finance the working capital needs of governments. Generally, they are issued in anticipation of various tax revenues, such as income, sales, property, use and business taxes, and are payable from these specific future taxes. Revenue anticipation notes are issued in expectation of receipt of other kinds of revenue, such as federal revenues available under federal revenue-sharing programs. Bond anticipation notes are issued to provide interim financing until long-term bond financing can be arranged. In most cases, the long-term bonds then provide the funds needed for repayment of the bond anticipation notes. Tax and revenue anticipation notes combine the funding sources of both tax anticipation notes and revenue anticipation notes. Construction loan notes are sold to provide construction financing. Mortgage notes insured by the Federal Housing Authority secure these notes; however, the proceeds from the insurance may be less than the economic equivalent of the payment of principal and interest on the mortgage note if there has been a default. The anticipated revenues from taxes, grants or bond financings generally secure the obligations of an issuer of municipal notes. An investment in such instruments, however, presents a risk that the anticipated revenues will not be received or that such revenues will be insufficient to satisfy the issuer’s payment obligations under the notes or that refinancing will be otherwise unavailable.

Pre-Refunded Municipal Securities. The principal of, and interest on, pre-refunded municipal securities are no longer paid from the original revenue source for the securities. Instead, the source of such payments is typically an escrow fund consisting of U.S. Government securities. The assets in the escrow fund are derived from the proceeds of refunding bonds issued by the same issuer as the

44

pre-refunded municipal securities. Issuers of municipal securities use this advance refunding technique to obtain more favorable terms with respect to securities that are not yet subject to call or redemption by the issuer. For example, advance refunding enables an issuer to refinance debt at lower market interest rates, restructure debt to improve cash flow or eliminate restrictive covenants in the indenture or other governing instrument for the pre-refunded municipal securities. However, except for a change in the revenue source from which principal and interest payments are made, the pre-refunded municipal securities remain outstanding on their original terms until they mature or are redeemed by the issuer.

Private Activity Bonds. Private activity bonds, formerly referred to as industrial development bonds, are issued by or on behalf of public authorities to obtain funds to provide privately operated housing facilities, airport, mass transit or port facilities, sewage disposal, solid waste disposal or hazardous waste treatment or disposal facilities and certain local facilities for water supply, gas or electricity. Other types of private activity bonds, the proceeds of which are used for the construction, equipment, repair or improvement of privately operated industrial or commercial facilities, may constitute municipal securities, although the current federal tax laws place substantial limitations on the size of such issues.

Inverse Floating Rate Securities. Inverse floating rate securities (sometimes referred to as “inverse floaters”) are securities whose interest rates bear an inverse relationship to the interest rate on another security or the value of an index. Generally, inverse floating rate securities represent beneficial interests in a special purpose trust formed by a third-party sponsor for the purpose of holding municipal bonds. The special purpose trust typically sells two classes of beneficial interests or securities: floating rate securities (sometimes referred to as short-term floaters or tender option bonds) and inverse floating rate securities (sometimes referred to as inverse floaters or residual interest securities). Both classes of beneficial interests are represented by certificates. The short-term floating rate securities have first priority on the cash flow from the municipal bonds held by the special purpose trust. Typically, a third party, such as a bank, broker-dealer or other financial institution, grants the floating rate security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees.

The holder of the short-term floater effectively holds a demand obligation that bears interest at the prevailing short-term, tax-exempt rate. However, the institution granting the tender option will not be obligated to accept tendered short-term floaters in the event of certain defaults or a significant downgrade in the credit rating assigned to the bond issuer. For its inverse floating rate investment, each Fund receives the residual cash flow from the special purpose trust. Because the holder of the short term floater is generally assured liquidity at the face value of the security, a Fund as the holder of the inverse floater assumes the interest rate cash flow risk and the market value risk associated with the municipal bond deposited into the special purpose trust. The volatility of the interest cash flow and the residual market value will vary with the degree to which the trust is leveraged. This is expressed in the ratio of the total face value of the short-term floaters in relation to the value of the inverse floaters that are issued by the special purpose trust, and can exceed three times for more “highly leveraged” trusts. All voting rights and decisions to be made with respect to any other rights relating to the municipal bonds held in the special purpose trust are passed through to the Funds, as the holder of the residual inverse floating rate securities.

Because increases in the interest rate on the short-term floaters reduce the residual interest paid on inverse floaters, and because fluctuations in the value of the municipal bond deposited in the special purpose trust affect the value of the inverse floater only, and not the value of the short-term floater

45

issued by the trust, inverse floaters’ value is generally more volatile than that of fixed rate bonds. The market price of inverse floating rate securities is generally more volatile than the underlying bonds due to the leveraging effect of this ownership structure. These securities generally will underperform the market of fixed rate bonds in a rising interest rate environment (i.e., when bond values are falling), but tend to out-perform the market of fixed rate bonds when interest rates decline or remain relatively stable. Although volatile, inverse floaters typically offer the potential for yields higher than those available on fixed rate bonds with comparable credit quality, coupon, call provisions and maturity. Inverse floaters have varying degrees of liquidity or illiquidity based upon the ability to sell the underlying bonds deposited in a special purpose trust at an attractive price.

Each Fund may invest in inverse floating rate securities issued by special purpose trusts whose sponsors have recourse to the Fund pursuant to a separate shortfall and forbearance agreement. Such an agreement would require a Fund to reimburse the third-party sponsor of the trust, upon termination of the trust issuing the inverse floater, for the difference between the liquidation value of the bonds held in the trust and the principal amount due to the holders of floating rate securities issued by the trust. A Fund will enter into such a recourse agreement (i) when the liquidity provider with respect to the floating rate securities issued by the special purpose trust requires such a recourse agreement because the level of leverage in the special purpose trust exceeds the level that the liquidity provider is willing to support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing the special purpose trust in the event that the municipal obligation held in the trust has declined in value. In an instance where a Fund has entered such a recourse agreement, the Fund may suffer a loss that exceeds the amount of its original investment in the inverse floating rate securities; such loss could be as great as that original investment amount plus the face amount of the floating rate securities issued by the trust.

Each Fund will segregate or earmark liquid assets with its custodian in accordance with the 1940 Act to cover its obligations with respect to its investments in special purpose trusts.

Each Fund invests in both inverse floating rate securities and floating rate securities (as discussed below) issued by the same special purpose trust.

Floating Rate Securities. Each Fund may also invest in floating rate securities, as described above, issued by special purpose trusts. Floating rate securities may take the form of short-term floating rate securities or the option period may be substantially longer. Generally, the interest rate earned will be based upon the market rates for municipal securities with maturities or remarketing provisions that are comparable in duration to the periodic interval of the tender option, which may vary from weekly, to monthly, to extended periods of one year or multiple years. Since the option feature has a shorter term than the final maturity or first call date of the underlying bond deposited in the trust, a Fund as the holder of the floating rate securities relies upon the terms of the agreement with the financial institution furnishing the option as well as the credit strength of that institution. As further assurance of liquidity, the terms of the trust provide for a liquidation of the municipal bond deposited in the trust and the application of the proceeds to pay off the floating rate securities. The trusts that are organized to issue both short-term floating rate securities and inverse floaters generally include liquidation triggers to protect the investor in the floating rate securities.

Special Taxing Districts. Special taxing districts are organized to plan and finance infrastructure developments to induce residential, commercial and industrial growth and redevelopment. The bond financing methods such as tax increment finance, tax assessment, special

46

services district and Mello-Roos bonds, are generally payable solely from taxes or other revenues attributable to the specific projects financed by the bonds without recourse to the credit or taxing power of related or overlapping municipalities. They often are exposed to real estate development-related risks and can have more taxpayer concentration risk than general tax-supported bonds, such as general obligation bonds.

Further, the fees, special taxes, or tax allocations and other revenues that are established to secure such financings are generally limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. The bonds could default if development failed to progress as anticipated or if larger taxpayers failed to pay the assessments, fees and taxes as provided in the financing plans of the districts.

When-Issued and Delayed-Delivery Transactions

Each Fund may buy and sell municipal securities on a when-issued or delayed-delivery basis, making payment or taking delivery at a later date, normally within 15 to 45 days of the trade date. This type of transaction may involve an element of risk because no interest accrues on the bonds prior to settlement and, because bonds are subject to market fluctuations, the value of the bonds at time of delivery may be less (or more) than cost. A separate account of each Fund will be established with its custodian consisting of cash, cash equivalents, or liquid securities having a market value at all times at least equal to the amount of the commitment.

Zero Coupon Bonds

A zero coupon bond is a bond that does not pay interest either for the entire life of the obligation or for an initial period after the issuance of the obligation. When held to its maturity, its return comes from the difference between the purchase price and its maturity value. A zero coupon bond is normally issued and traded at a deep discount from face value. Zero coupon bonds allow an issuer to avoid or delay the need to generate cash to meet current interest payments and, as a result, may involve greater credit risk than bonds that pay interest currently or in cash. A Fund would be required to distribute the income on any of these instruments as it accrues, even though the Fund will not receive all of the income on a current basis or in cash. Thus, a Fund may have to sell other investments, including when it may not be advisable to do so, to make income distributions to its shareholders.

Structured Notes

Each Fund may utilize structured notes and similar instruments for investment purposes and also for hedging purposes. Structured notes are privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a benchmark asset, market or interest rate (an “embedded index”), such as selected securities, an index of securities or specified interest rates, or the differential performance of two assets or markets. The terms of such structured instruments normally provide that their principal and/or interest payments are to be adjusted upwards or downwards (but not ordinarily below zero) to reflect changes in the embedded index while the structured instruments are outstanding. As a result, the interest and/or principal payments that may be made on a structured product may vary widely, depending upon a variety of factors, including the volatility of the embedded index and the effect of changes in the embedded index on principal and/or interest payments. The rate of return on structured notes may be determined by applying a multiplier to

47

the performance or differential performance of the referenced index or indices or other assets. Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss. These types of investments may generate taxable income.

Derivatives

Each Fund may invest in certain derivative instruments in pursuit of its investment objectives. Such instruments include financial futures contracts, swap contracts (including interest rate and credit default swaps), options on financial futures, options on swap contracts or other derivative instruments. In particular, a Fund may use credit default swaps and interest rate swaps. Credit default swaps may require initial premium (discount) payments as well as periodic payments (receipts) related to the interest leg of the swap or to the default of a reference obligation. If a Fund is a seller of a contract, the Fund would be required to pay the par (or other agreed upon) value of a referenced debt obligation to the counterparty in the event of a default or other credit event by the reference issuer, such as a U.S. or foreign corporate issuer, with respect to such debt obligations. In return, such Fund would receive from the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, such Fund would keep the stream of payments and would have no payment obligations. As the seller, a Fund would be subject to investment exposure on the notional amount of the swap. If a Fund is a buyer of a contract, the Fund would have the right to deliver a referenced debt obligation and receive the par (or other agreed-upon) value of such debt obligation from the counterparty in the event of a default or other credit event (such as a credit downgrade) by the reference issuer, such as a U.S. or foreign corporation, with respect to its debt obligations. In return, such Fund would pay the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the counterparty would keep the stream of payments and would have no further obligations to such Fund. Interest rate swaps involve the exchange by a Fund with a counterparty of their respective commitments to pay or receive interest, such as an exchange of fixed-rate payments for floating rate payments. A Fund will usually enter into interest rate swaps on a net basis; that is, the two payment streams will be netted out in a cash settlement on the payment date or dates specified in the instrument, with the Fund receiving or paying, as the case may be, only the net amount of the two payments.

The Adviser may use derivative instruments to seek to enhance return, to hedge some of the risk of each Fund’s investments in municipal securities or as a substitute for a position in the underlying asset. These types of strategies may generate taxable income.

There is no assurance that these derivative strategies will be available at any time or that the Adviser will determine to use them for a Fund or, if used, that the strategies will be successful.

Other Investment Companies

Each Fund may invest up to 10% of its Managed Assets in securities of other open- or closed-end investment companies (including exchange-traded funds (“ETFs”)) that invest primarily in municipal securities of the types in which the Fund may invest directly. In addition, each Fund may invest a portion of its Managed Assets in pooled investment vehicles (other than investment companies) that invest primarily in municipal securities of the types in which the Fund may invest directly. Each Fund generally expects that it may invest in other investment companies and/or other pooled investment vehicles either during periods when it has large amounts of uninvested cash or during periods when there is a shortage of attractive, high-yielding municipal securities available in the

48

market. Each Fund may invest in investment companies that are advised by the Adviser or its affiliates to the extent permitted by applicable law and/or pursuant to exemptive relief from the SEC. As a shareholder in an investment company, a Fund will bear its ratable share of that investment company’s expenses and would remain subject to payment of the Fund’s advisory and administrative fees with respect to assets so invested. Common shareholders would therefore be subject to duplicative expenses to the extent a Fund invests in other investment companies.

The Adviser will take expenses into account when evaluating the investment merits of an investment in an investment company relative to available municipal security investments. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to the same leverage risks described herein. The net asset value and market value of leveraged shares will be more volatile, and the yield to common shareholders will tend to fluctuate more than the yield generated by unleveraged shares.

Investment Portfolio and Capital Structure Strategies to Manage Leverage Risk

Common shareholders of each Fund are subject to the risks of leverage primarily in the form of additional common share earnings and net asset value risk, associated with a Fund’s use of financial leverage in the form of preferred shares or inverse floating rate securities.

In an effort to mitigate these risks, each Fund and the Adviser seek to maintain the Fund’s financial leverage within an established range, and to rebalance leverage levels if the Fund’s leverage ratio moves outside this range to a meaningful degree for a persistent period of time. A Fund may rebalance leverage levels in one or more ways, including by increasing/reducing the amount of leverage outstanding and issuing/repurchasing common shares. Reducing leverage may require a Fund to raise cash through the sale of portfolio securities at times and/or at prices that would otherwise be unattractive for the Fund. Each Fund may also seek to diversify its capital structure and the risks associated with leverage by employing multiple forms of leverage. Each Fund and the Adviser will weigh the relative potential benefits and risks as well as the costs associated with a particular action, and will take such action only if it determines that on balance the likely potential benefits outweigh the associated risks and costs.

Because the long-term municipal securities in which a Fund invests generally pay fixed rates of interest while the Fund’s costs of leverage generally fluctuate with short-term yields, common shareholders bear incremental earnings risk from leverage.

Hedging Strategies

Each Fund may use various investment strategies designed to limit the risk of bond price fluctuations and to preserve capital. These hedging strategies include using credit default swaps, interest rate swaps on taxable or tax-exempt indices, forward start interest rate swaps and options on interest rate swaps, financial futures contracts, options on financial futures or options based on either an index of long-term municipal securities or on taxable debt securities whose prices, in the opinion of the Adviser, correlate with the prices of a Fund’s investments. These hedging strategies may generate taxable income.

The Board of each Fund recommends that shareholders vote “FOR” the approval of the Reorganization.

49

PROPOSAL NO. 2—APPROVAL OF ISSUANCE OF ADDITIONAL COMMON SHARES OF ACQUIRING FUND (ACQUIRING FUND SHAREHOLDERS ONLY)

In connection with the proposed Reorganizations, the Acquiring Fund will issue additional Acquiring Fund common shares and, subject to notice of issuance, list such shares on the NYSE MKT and will issue VRDP Shares. The Acquiring Fund will acquire substantially all of the assets of each Acquired Fund in exchange for newly issued Acquiring Fund common shares and Acquiring Fund VRDP Shares and the assumption of substantially all of the liabilities of each Acquired Fund. Each Acquired Fund will distribute Acquiring Fund common shares to its common shareholders and Acquiring Fund VRDP Shares to its preferred shareholders and will then terminate its registration under the 1940 Act and dissolve under applicable state law. The Acquiring Fund’s Board, based upon its evaluation of all relevant information, anticipates that the Reorganizations may benefit holders of the Acquiring Fund’s common shares and preferred shares due to the increased size of the combined Fund.

The aggregate net asset value of Acquiring Fund common shares received by an Acquired Fund in each Reorganization will equal the aggregate net asset value of the Acquired Fund’s common shares outstanding, in each case as of the Valuation Time. Prior to the Valuation Time, the net asset value of each Acquired Fund and the Acquiring Fund will be reduced by the costs of the Reorganization borne by such Fund. No fractional Acquiring Fund common shares will be issued to an Acquired Fund’s shareholders and, in lieu of such fractional shares, an Acquired Fund’s shareholders will receive cash in an amount equal to the value received for such shares in the open market, which may be higher or lower than net asset value. The aggregate liquidation preference of each series of Acquiring Fund VRDP Shares received in each Reorganization will equal the aggregate liquidation preference of the corresponding Acquired Fund’s VRDP Shares held immediately prior to the Reorganization. The Reorganizations will result in no reduction in net asset value of the Acquiring Fund’s common shares, other than to reflect the costs of the Reorganization. No gain or loss will be recognized by the Acquiring Fund for federal income tax purposes as a direct result of the Reorganizations. As a result of the Reorganizations, common shareholders of the Acquiring Fund will hold a smaller percentage of the outstanding voting shares of the combined fund. The Acquiring Fund will continue to operate as a registered closed-end management investment company with the investment objectives and policies described in this Joint Proxy Statement/Prospectus.

While applicable state and federal law does not require the common shareholders of the Acquiring Fund to approve the issuance of additional Acquiring Fund common shares, applicable NYSE MKT rules require shareholder approval of additional Acquiring Fund common shares to be issued in connection with the Reorganizations, and the Acquiring Fund’s Statement Establishing and Fixing the Rights and Preferences of the MTP Shares (the “MTP Statement”) and the Acquiring Fund’s Statement Establishing and Fixing the Rights and Preferences of the VMTP Shares (the “VMTP Statement”) require the common shareholders and preferred shareholders of the Acquiring Fund to vote together on matters submitted to a vote of shareholders.

Shareholder approval of the issuance of additional common shares of the Acquiring Fund requires the affirmative vote of a majority of the votes cast on the proposal, provided that the total votes cast on the proposal represent over 50% of the shares entitled to vote on the matter. Abstentions and broker non-votes will have no effect on the proposal. Broker non-votes represent shares held by brokers or nominees for which the brokers or nominees have executed proxies as to which (i) the broker or nominee does not have discretionary voting power and (ii) the broker or nominee has not received instructions from the beneficial owner or other person who is entitled to instruct how the shares will be voted.

50

The consummation of the Reorganizations is contingent on the satisfaction or waiver of all closing conditions including approval of the proposals relating to the Reorganizations by each Acquired Fund’s shareholders and the Acquiring Fund’s preferred shareholders.

The Board of the Acquiring Fund recommends that shareholders of the Acquiring Fund vote “FOR” the approval of the issuance of additional Acquiring Fund common shares in connection with the Reorganizations.

ADDITIONAL INFORMATION ABOUT THE ACQUIRING FUND

Certain Provisions in the Acquiring Fund’s Declaration of Trust and By-Laws

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Acquiring Fund. However, the Acquiring Fund’s Declaration of Trust contains an express disclaimer of shareholder liability for debts or obligations of the Fund and requires that notice of such limited liability be given in each agreement, obligation or instrument entered into or executed by the Fund or the trustees. The Acquiring Fund’s Declaration of Trust further provides for indemnification out of the assets and property of the Fund for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which the Acquiring Fund would be unable to meet its obligations. The Acquiring Fund believes that the likelihood of such circumstances is remote.

The Acquiring Fund’s Declaration of Trust includes provisions that could limit the ability of other entities or persons to acquire control of the Fund or to convert the Fund to open-end status. Specifically, the Acquiring Fund’s Declaration of Trust requires a vote by holders of at least two-thirds of the outstanding common shares and preferred shares, voting as a single class, except as described below, to authorize (1) a conversion of the Fund from a closed-end to an open-end investment company, (2) a merger or consolidation of the Fund, or a series or class of the Fund, with any corporation, association, trust or other organization or a reorganization or recapitalization of the Fund, or a series or class of the Fund, (3) a sale, lease or transfer of all or substantially all of the Fund’s assets (other than in the regular course of the Fund’s investment activities), (4) in certain circumstances, a termination of the Fund, or a series or class of the Fund, or (5) a removal of trustees by shareholders, and then only for cause, unless, with respect to (1) through (4), such transaction has already been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Acquiring Fund’s Declaration of Trust or the Acquiring Fund’s By-Laws, in which case the affirmative vote of the holders of at least a majority of the Fund’s outstanding common shares and preferred shares, voting as a single class, is required, provided, however, that, where only a particular class or series is affected (or, in the case of removing a trustee, when the trustee has been elected by only one class), only the required vote by the applicable class or series will be required. The voting provisions of the Declaration of Trust are not to be construed as requiring shareholder approval for any transaction, whether deemed a merger, consolidation, reorganization or otherwise, whereby the Acquiring Fund issues shares in connection with the acquisition of assets (including those subject to liabilities) from any other investment company or similar entity. In the case of the conversion of the Acquiring Fund to an open-end investment company, or in the case of any of the foregoing transactions constituting a plan of reorganization (as that term is used in the 1940 Act) which adversely affects the holders of preferred shares, the action in question will also require the affirmative vote of the holders

51

of at least two-thirds of the Acquiring Fund’s preferred shares outstanding at the time, voting as a separate class, or, if such action has been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Acquiring Fund’s Declaration of Trust or the Acquiring Fund’s By-Laws, the affirmative vote of the holders of at least a majority of the Acquiring Fund’s preferred shares outstanding at the time, voting as a separate class. None of the foregoing voting provisions may be amended or repealed except by the vote of at least two-thirds of the common shares and preferred shares, voting as a single class. The votes required to approve the conversion of the Acquiring Fund from a closed-end to an open-end investment company or to approve transactions constituting a plan of reorganization which adversely affects the holders of preferred shares are higher than those required by the 1940 Act. The Acquiring Fund’s Board believes that the provisions of the Acquiring Fund’s Declaration of Trust relating to such higher votes are in the best interest of the Acquiring Fund.

The Declaration of Trust provides that the obligations of the Acquiring Fund are not binding upon the Fund’s trustees individually, but only upon the assets and property of the Fund, and that the trustees shall not be liable for errors of judgment or mistakes of fact or law. Nothing in the Acquiring Fund’s Declaration of Trust, however, protects a trustee against any liability to which he or she would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office.

In addition, the By-laws require the Board be divided into three classes with staggered terms. See the Reorganization SAI under “Management of the Funds.” This provision of the By-laws could delay for up to two years the replacement of a majority of the Board. Holders of preferred shares, voting as a separate class, are entitled to elect two of the Fund’s trustees.

The provisions of the Acquiring Fund’s Declaration of Trust and By-laws described above could have the effect of depriving the common shareholders of opportunities to sell their common shares at a premium over the then-current market price of the common shares by discouraging a third party from seeking to obtain control of the Fund in a tender offer or similar transaction. The overall effect of these provisions is to render more difficult the accomplishment of a merger or the assumption of control by a third party. They provide, however, the advantage of potentially requiring persons seeking control of the Acquiring Fund to negotiate with its management regarding the price to be paid and facilitating the continuity of the Fund’s investment objectives and policies. The Acquiring Fund’s Board has considered the foregoing anti-takeover provisions and concluded that they are in the best interests of the Fund.

The Acquiring Fund’s Declaration of Trust provides that common shareholders shall have no right to acquire, purchase or subscribe for any shares or securities of the Fund, other than such right, if any, as the Fund’s Board in its discretion may determine.

Reference should be made to the Acquiring Fund’s Declaration of Trust on file with the SEC for the full text of these provisions.

Repurchase of Common Shares; Conversion to Open-End Fund

The Acquiring Fund is a closed-end management investment company, and as such its shareholders do not have the right to cause the Acquiring Fund to redeem their common shares. Instead, the common shares of the Acquiring Fund trade in the open market at a price that is a function of several factors, including dividend levels (which are in turn affected by expenses), net asset value,

52

call protection, dividend stability, portfolio credit quality, relative demand for and supply of such shares in the market, general market and economic conditions and other factors. Because common shares of closed-end management investment companies may frequently trade at prices lower than net asset value, the Acquiring Fund’s Board has determined that, at least annually, it will consider action that might be taken to reduce or eliminate any material discount from net asset value in respect of common shares, which may include the repurchase of such shares in the open market or in private transactions, the making of a tender offer for such shares at net asset value, or the conversion of the Acquiring Fund to an open-end investment company. There is no assurance that the Acquiring Fund’s Board will decide to take any of these actions, or that share repurchases or tender offers will actually reduce market discount.

Notwithstanding the foregoing, at any time when the Acquiring Fund’s preferred shares are outstanding, the Acquiring Fund may not purchase, redeem or otherwise acquire any of its common shares unless (1) all accumulated but unpaid preferred shares dividends due to be paid have been paid and (2) at the time of such purchase, redemption or acquisition, the net asset value of the Acquiring Fund’s portfolio (determined after deducting the acquisition price of the common shares) is at least 200% of the liquidation value (expected to equal the original purchase price per share plus any accumulated but unpaid dividends thereon) of the outstanding preferred shares, including MTP Shares, VMTP Shares and VRDP Shares.

If the Acquiring Fund converted to an open-end investment company, it would be required to redeem all its preferred shares, including MTP Shares, VMTP Shares and VRDP Shares, then outstanding (requiring in turn that it liquidate a portion of its investment portfolio), and the common shares would no longer be listed on an exchange. In contrast to a closed-end management investment company, shareholders of an open-end management investment company may require the company to redeem their shares at any time (except in certain circumstances as authorized by or under the 1940 Act) at their net asset value, less any redemption charge that is in effect at the time of redemption. See “Certain Provisions in the Acquiring Fund’s Declaration of Trust and By-Laws” above for a discussion of the voting requirements applicable to the conversion of the Acquiring Fund to an open-end management investment company.

Before deciding whether to take any action if the common shares trade below net asset value, the Board would consider all relevant factors, including the extent and duration of the discount, the liquidity of the Acquiring Fund’s portfolio, the impact of any action that might be taken on the Acquiring Fund or its shareholders, and market considerations. Based on these considerations, even if the Acquiring Fund’s common shares should trade at a discount, the Board may determine that, in the interest of the Acquiring Fund, no action should be taken. See the Reorganization SAI under “Repurchase of Common Shares; Conversion to Open-End Fund” for a further discussion of possible action to reduce or eliminate such discount to net asset value.

Description of Outstanding Acquiring Fund MTP Shares

General

The Acquiring Fund currently has outstanding 8,300,000 MTP Shares, with a $10.00 liquidation preference per share, which will remain outstanding following the completion of the Reorganizations. Proceeds from the issuance of the MTP Shares, net of offering expenses, were used to redeem the Acquiring Fund’s outstanding auction rate preferred shares.

53

Dividends

The holders of the MTP Shares are entitled to receive cumulative cash dividends and distributions on such shares when, as and if declared by, or under authority granted by, the Acquiring Fund’s Board. Dividends on the MTP Shares will be payable monthly based on the fixed dividend rate set forth in the MTP Statement.

Redemption

The MTP Shares are subject to optional and mandatory redemption in certain circumstances. The Acquiring Fund is obligated to redeem the MTP Shares on February 1, 2015, unless earlier redeemed or repurchased by the Acquiring Fund, at a redemption price equal to the liquidation preference per share ($10.00) plus an amount equal to accumulated but unpaid dividends thereon. The MTP Shares also may be redeemed in whole or in part at the option of the Acquiring Fund at a redemption price equal to the liquidation preference, plus an amount equal to all unpaid dividends and distributions accumulated to (but excluding) the optional redemption date (whether or not earned by the Acquiring Fund, but excluding interest thereon). In the event the Acquiring Fund fails to comply with its effective leverage ratio requirements and any such failure is not cured within the applicable cure period, the Acquiring Fund may become obligated to redeem a number of MTP Shares or other preferred shares necessary to regain compliance with such requirements.

Voting and Consent Rights

Except as otherwise provided in the Acquiring Fund’s Declaration of Trust, the MTP Statement, or as otherwise required by applicable law, (i) each holder of MTP Shares is entitled to one vote for each MTP Share held on each matter submitted to a vote of shareholders of the Acquiring Fund, and (ii) the holders of the MTP Shares, along with holders of other outstanding preferred shares of the Acquiring Fund, vote with holders of common shares of the Acquiring Fund as a single class; provided, however, that holders of preferred shares, including MTP Shares, are entitled as a class to elect two trustees of the Acquiring Fund at all times. The holders of outstanding common shares and preferred shares, including MTP Shares, voting as a single class, elect the balance of the trustees of the Acquiring Fund.

The holders of the MTP Shares, as a separate class, have voting and consent rights with respect to certain actions that would materially and adversely affect any preference, right or power of the MTP Shares or the holders of the MTP Shares. The holders of the MTP Shares also are entitled to vote as a class with holders of other preferred shares of the Acquiring Fund on matters that relate to the conversion of the Acquiring Fund to an open-end investment company, certain plans of reorganization adversely affecting holders of the preferred shares or any other action requiring a vote of security holders of the Acquiring Fund under Section 13(a) of the 1940 Act. In certain circumstances, holders of preferred shares, including the MTP Shares, are entitled to elect additional trustees in the event at least two full years’ dividends are due and unpaid and sufficient cash or specified securities have not been deposited for their payment, or at any time holders of preferred shares are entitled under the 1940 Act to elect a majority of the trustees of the Acquiring Fund.

Priority of Payment

The MTP Shares are senior securities in priority to the Acquiring Fund’s common shares as to the payment of dividends and as to the distribution of assets upon dissolution, liquidation or winding

54

up of the affairs of the Acquiring Fund. The MTP Shares have equal priority as to payments of dividends and as to the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund with other preferred shares of the Acquiring Fund, including outstanding VMTP Shares and the VRDP Shares to be issued in connection with the Reorganizations.

Description of Outstanding Acquiring Fund VMTP Shares

General

The Acquiring Fund currently has outstanding 676 VMTP Shares, par value $0.01 per share, with a total liquidation value of $67,600,000, which will remain outstanding following the completion of the Reorganizations. The VMTP Shares were offered and sold by the Acquiring Fund to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, with all proceeds, net of offering expenses, used to redeem the Acquiring Fund’s outstanding auction rate preferred securities.

Dividends

Holders of VMTP Shares are entitled to receive cash dividends when, as and if declared by the Acquiring Fund’s Board. The amount of dividends per VMTP Share payable on any dividend payment date will equal the sum of dividends accumulated but not yet paid for each rate period during the relevant monthly dividend period. The dividend rate applicable to any rate period (which typically consists of seven days) is an index rate based on the SIFMA Municipal Swap Index plus an applicable spread. The applicable spread is subject to adjustment in certain circumstances, including a change in the credit rating assigned to the VMTP Shares.

Redemption

VMTP Shares are subject to optional and mandatory redemption in certain circumstances. The Acquiring Fund is obligated to redeem the VMTP Shares on August 1, 2014, unless earlier redeemed or repurchased by the Acquiring Fund, at a redemption price per share equal to the liquidation value per share ($100,000) plus any accumulated but unpaid dividends. VMTP Shares also may be redeemed in whole or in part at the option of the Acquiring Fund at a redemption price per share equal to the liquidation value per share plus any accumulated but unpaid dividends. In the event the Acquiring Fund fails to comply with asset coverage and/or effective leverage ratio requirements and any such failure is not cured within the applicable cure period, the Acquiring Fund may become obligated to redeem such number of preferred shares as are necessary to achieve compliance with such requirements.

Voting and Consent Rights

Except as otherwise provided in the Acquiring Fund’s Declaration of Trust, the VMTP Statement, or as otherwise required by applicable law, (i) each holder of VMTP Shares is entitled to one vote for each VMTP Share held on each matter submitted to a vote of shareholders of the Acquiring Fund, and (ii) the holders of VMTP Shares, along with holders of other outstanding preferred shares of the Acquiring Fund vote with holders of common shares of the Acquiring Fund as a single class; provided, however, that holders of preferred shares, including VMTP Shares, are entitled as a class to elect two trustees of the Acquiring Fund at all times. The holders of outstanding common shares and preferred shares, including VMTP Shares, voting as a single class, elect the balance of the trustees of the Acquiring Fund.

55

Holders of VMTP Shares, as a separate class, have voting and consent rights with respect to certain actions that would materially and adversely affect any preference, right or power of the VMTP Shares or holders of VMTP Shares. In addition, holders of VMTP Shares have certain consent rights under the purchase agreement for the VMTP Shares with respect to certain actions that would affect their investment in the Acquiring Fund. Holders of VMTP Shares also are entitled to vote as a class with holders of other preferred shares of the Acquiring Fund on matters that relate to the conversion of the Acquiring Fund to an open-end investment company, certain plans of reorganization adversely affecting holders of the preferred shares or any other action requiring a vote of security holders of the Acquiring Fund under Section 13(a) of the 1940 Act. In certain circumstances, holders of preferred shares, including VMTP Shares, are entitled to elect additional trustees in the event at least two full years’ dividends are due and unpaid and sufficient cash or specified securities have not been deposited for their payment, or at any time holders of preferred shares are entitled under the 1940 Act to elect a majority of the trustees of the Acquiring Fund.

Priority of Payment

The VMTP Shares are senior in priority to the Acquiring Fund’s common shares as to the payment of dividends and as to the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund. The VMTP Shares have equal priority as to the payment of dividends and as to distribution of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund with other preferred shares of the Acquiring Fund, including outstanding MTP Shares and the VRDP Shares to be issued in the Reorganizations.

Custodian, Transfer Agent, Dividend Disbursing Agent and Redemption Agent

The custodian of the assets of the Acquiring Fund is State Street Bank and Trust Company (“State Street”), One Lincoln Street, Boston, Massachusetts 02111. The custodian performs custodial, fund accounting and portfolio accounting services. The Acquiring Fund’s transfer, shareholder services and dividend disbursing agent and redemption and paying agent with respect to the common shares is also State Street, 250 Royall Street, Canton, Massachusetts 02021. State Street has subcontracted the transfer agency servicing of the Acquiring Fund to Computershare, Inc.

Federal Income Tax Matters Associated with Investment in the Acquiring Fund

The following information is meant as a general summary of certain federal income tax matters for U.S. shareholders. Please see the Reorganization SAI for additional information. Investors should rely on their own tax adviser for advice about the particular federal, state and local tax consequences to them of investing in the Acquiring Fund.

The Acquiring Fund has elected to be treated and intends to qualify each year (including the taxable year in which the Reorganizations occur) as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). In order to qualify as a RIC, the Acquiring Fund must satisfy certain requirements regarding the sources of its income, the diversification of its assets and the distribution of its income. As a RIC, the Acquiring Fund is not expected to be subject to federal income tax on the income and gains it distributes to its shareholders. The Acquiring Fund primarily invests in municipal securities the income from which is exempt from regular federal income tax. Thus, substantially all of the Acquiring Fund’s dividends paid to you should qualify as “exempt-interest dividends.” A shareholder treats an exempt-interest dividend as interest on state and local bonds exempt from regular federal income tax. Federal income tax law

56

imposes an alternative minimum tax with respect to corporations, individuals, trusts and estates. Interest on certain municipal obligations, such as certain private activity bonds, is included as an item of tax preference in determining the amount of a taxpayer’s alternative minimum taxable income. To the extent that the Acquiring Fund receives income from such municipal obligations, a portion of the dividends paid by the Acquiring Fund, although exempt from regular federal income tax, will be taxable to shareholders to the extent that their tax liability is determined under the federal alternative minimum tax. The Acquiring Fund, however, attempts to limit income subject to the federal alternative minimum tax applicable to individuals. The Acquiring Fund will annually provide a report indicating the percentage of the Acquiring Fund’s income attributable to municipal obligations subject to the federal alternative minimum tax. Corporations are subject to special rules in calculating their federal alternative minimum taxable income with respect to interest from such municipal obligations.

On September 12, 2011, President Obama submitted to Congress the American Jobs Act of 2011. If enacted in its proposed form, this Act generally would limit the exclusion from gross income of tax-exempt interest (which includes exempt-interest dividends received from the Acquiring Fund) for individuals whose adjusted gross income for federal income tax purposes exceeds certain thresholds for taxable years beginning on or after January 1, 2013 in order to provide a tax benefit not greater than 28% of such interest. Such proposal could affect the value of the municipal bonds owned by the Acquiring Fund. The likelihood of the Act being enacted in the form introduced or in some other form cannot be predicted. Shareholders should consult their own tax advisers regarding the potential consequences of this Act on their investment in the Acquiring Fund.

In addition to exempt-interest dividends, the Acquiring Fund may also distribute to its shareholders amounts that are treated as long-term capital gain or ordinary income (which may include short-term capital gains). These distributions may be subject to federal, state and local taxation, depending on a shareholder’s situation. If so, they are taxable whether or not such distributions are reinvested. Net capital gain distributions (the excess of net long-term capital gain over net short-term capital loss) are generally taxable at rates applicable to long-term capital gains regardless of how long a shareholder has held its shares. Long-term capital gains are currently taxable to noncorporate shareholders at a maximum federal income tax rate of 15%. Absent further legislation, the maximum 15% rate on long-term capital gains will cease to apply to taxable years beginning after December 31, 2012. In addition, for taxable years beginning after December 31, 2012, certain individuals, estates and trusts will be subject to a 3.8% Medicare tax on net investment income, including net capital gains and other taxable dividends. The Acquiring Fund does not expect that any part of its distributions to shareholders from its investments will qualify for the dividends-received deduction available to corporate shareholders or as “qualified dividend income” to noncorporate shareholders.

As a RIC, the Acquiring Fund will not be subject to federal income tax in any taxable year provided that it meets certain distribution requirements. The Acquiring Fund may retain for investment some (or all) of its net capital gain. If the Acquiring Fund retains any net capital gain or investment company taxable income, it will be subject to tax at regular corporate rates on the amount retained. If the Acquiring Fund retains any net capital gain, it may designate the retained amount as undistributed capital gains in a notice to its shareholders who, if subject to federal income tax on long-term capital gains, (i) will be required to include in income for federal income tax purposes, as long-term capital gain, their share of such undistributed amount; (ii) will be entitled to credit their proportionate shares of the federal income tax paid by the Acquiring Fund on such undistributed amount against their federal income tax liabilities, if any; and (iii) may claim refunds to the extent the credit exceeds such liabilities. For federal income tax purposes, the basis of shares owned by a shareholder of the

57

Acquiring Fund will be increased by an amount equal to the difference between the amount of undistributed capital gains included in the shareholder’s gross income and the tax deemed paid by the shareholder under clause (ii) of the preceding sentence.

The IRS currently requires that a RIC that has two or more classes of stock allocate to each such class proportionate amounts of each type of its income (such as exempt interest, ordinary income and capital gains). Accordingly, the Acquiring Fund designates dividends made with respect to common shares and preferred shares as consisting of particular types of income (e.g., exempt interest, net capital gain and ordinary income) in accordance with each class’ proportionate share of the total dividends paid by the Acquiring Fund during the year.

Dividends declared by the Acquiring Fund to shareholders of record in October, November or December and paid during the following January will be treated as having been received by shareholders in the year the distributions were declared.

Each shareholder will receive an annual statement summarizing the shareholder’s dividend and capital gains distributions.

The redemption, sale or exchange of shares normally will result in capital gain or loss to shareholders who hold their shares as capital assets. Generally, a shareholder’s gain or loss will be long-term capital gain or loss if the shares have been held for more than one year even though the increase in value in such shares is attributable to tax-exempt interest income. The gain or loss on shares held for one year or less will generally be treated as short-term capital gain or loss. Present law taxes both long-term and short-term capital gains of corporations at the same rates applicable to ordinary income. For non-corporate taxpayers, however, long-term capital gains are currently taxed at a maximum federal income tax rate of 15%, while short-term capital gains and other ordinary income are currently taxed at ordinary income rates. As noted above, absent further legislation, the maximum rates applicable to long-term capital gains will cease to apply to taxable years beginning after December 31, 2012 and an additional 3.8% Medicare tax may apply to certain individual, estate or trust shareholders’ taxable distributions and to capital gain distributions for taxable years beginning after December 31, 2012. Any loss on the sale of shares that have been held for six months or less will be disallowed to the extent of any distribution of exempt-interest dividends received with respect to such shares, unless the shares are of a RIC that declares exempt-interest dividends on a daily basis in an amount equal to at least 90% of its net tax-exempt interest and distributes such dividends on a monthly or more frequent basis. Any remaining loss on the sale or disposition of shares held for six months or less will be treated as a long-term capital loss to the extent of any net capital gain distributions received by the shareholder on such shares. Any loss realized on a sale or exchange of shares of the Acquiring Fund will be disallowed to the extent those shares of the Acquiring Fund are replaced by other substantially identical shares of the Acquiring Fund or other substantially identical stock or securities (including through reinvestment of dividends) within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of the original shares. In that event, the basis of the replacement shares will be adjusted to reflect the disallowed loss.

Any interest on indebtedness incurred or continued to purchase or carry the Acquiring Fund’s shares to which exempt-interest dividends are allocated is not deductible. Under certain applicable rules, the purchase or ownership of shares may be considered to have been made with borrowed funds even though such funds are not directly used for the purchase or ownership of the shares. In addition, if you receive Social Security or certain railroad retirement benefits, you may be subject to U.S. federal

58

income tax on a portion of such benefits as a result of receiving investment income, including exempt-interest dividends and other distributions paid by the Acquiring Fund.

If the Acquiring Fund invests in certain pay-in-kind securities, zero coupon securities, deferred interest securities or, in general, any other securities with original issue discount (or with market discount if the Acquiring Fund elects to include market discount in income currently), the Acquiring Fund must accrue income on such investments for each taxable year, which generally will be prior to the receipt of the corresponding cash payments. However, the Acquiring Fund must distribute to shareholders, at least annually, all or substantially all of its investment company taxable income (determined without regard to the deduction for dividends paid) and its net tax-exempt income, including such accrued income, to qualify as a RIC and (with respect to its ordinary income and taxable gain) to avoid federal income and excise taxes. Therefore, the Acquiring Fund may have to dispose of its portfolio securities under disadvantageous circumstances to generate cash, or may have to leverage itself by borrowing the cash, to satisfy these distribution requirements.

The Acquiring Fund may hold or acquire municipal obligations that are market discount bonds. A market discount bond is a security acquired in the secondary market at a price below its redemption value (or its adjusted issue price if it is also an original issue discount bond). If the Acquiring Fund invests in a market discount bond, it will be required to treat any gain recognized on the disposition of such market discount bond as ordinary taxable income to the extent of the accrued market discount.

The Acquiring Fund may be required to withhold U.S. federal income tax at the current rate of 28% of all distributions (including exempt-interest dividends) and redemption proceeds payable to a shareholder if the shareholder fails to provide the Acquiring Fund with his or her correct taxpayer identification number or to make required certifications, or if the shareholder has been notified by the IRS (or the IRS notifies the Fund) that he or she is subject to backup withholding. After 2012, the backup withholding rate will increase to 31% absent legislative change. Backup withholding is not an additional tax; rather, it is a way in which the IRS ensures it will collect taxes otherwise due. Any amounts withheld may be credited against a shareholder’s U.S. federal income tax liability.

Net Asset Value

The Acquiring Fund’s net asset value per common share is determined as of the close of the regular session trading (normally 4:00 p.m. Eastern time) on each day the NYSE is open for business. Net asset value is calculated by taking the market value of the Acquiring Fund’s total assets, including interest or dividends accrued but not yet collected, less all liabilities, and dividing by the total number of shares outstanding. The result, rounded to the nearest cent, is the net asset value per share. All valuations are subject to review by the Acquiring Fund’s Board or its delegate.

In determining net asset value per common share, expenses are accrued and applied daily and securities and other assets for which market quotations are available are valued at market value. The prices of municipal bonds are provided by a pricing service approved by the Acquiring Fund’s Board. When market price quotes are not readily available (which is usually the case for municipal securities), the pricing service, or, in the absence of a pricing service for a particular security, the Board of the Acquiring Fund, or its designee, may establish fair market value using a wide variety of market data including yields or prices of municipal bonds of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from securities dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant by the pricing service or the Board’s designee.

VRDP Shares are designed to be eligible for purchase by money market funds. Based on information provided by remarketing agents for the VRDP Shares, money market funds within certain fund complexes may hold, in the aggregate, greater than 5% of the outstanding VRDP Shares of one or more Funds, and individual money market funds within such complexes may beneficially own an indeterminable amount of VRDP Shares exceeding 5% of the outstanding VRDP Shares of one or more Funds. Information with respect to aggregate holdings of VRDP Shares associated with fund complexes identified by the remarketing agents (number of VRDP Shares and percentage of total outstanding) is as follows: Premium Opportunity: Schwab (1,195 shares (54.57%)), Federated (919 shares (41.96%)), Morgan Stanley (76 shares (3.47%)); Premier Opportunity: Blackrock (69 shares (5.27%)), JP Morgan (220 shares (16.81%)), Federated (240 shares (18.33%)), Schwab (240 shares (18.33%)), Vanguard (240 shares (18.33%)), Bank of America Global (150 shares (11.46%)) and Morgan Stanley (150 shares (11.46%)). Based on the preferred shares outstanding as of October 19, 2012, the estimated pro forma percentage owned of all preferred shares of the combined fund would be less than approximately 0.02% for each holder of VRDP Shares listed above.

Expenses of Proxy Solicitation

The cost of preparing, printing and mailing the enclosed proxy, accompanying notice and proxy statement and all other costs in connection with the solicitation of proxies will be paid by the Funds pro rata based on the projected net benefit and cost savings to each Fund. Additional solicitation may be made by letter or telephone by officers or employees of Nuveen or the Adviser, or by dealers and their representatives. Any additional costs of solicitation will be paid by the Fund that requires additional solicitation.

62

Other Information

Management of the Funds does not intend to present and does not have reason to believe that others will present any items of business at the Special Meetings, except as described in this Joint Proxy Statement/Prospectus. However, if other matters are properly presented at the meetings for a vote, the proxies will be voted upon such matters in accordance with the judgment of the persons acting under the proxies.

A list of shareholders of each Fund entitled to be present and to vote at the Special Meetings will be available at the offices of the Funds, 333 West Wacker Drive, Chicago, Illinois, for inspection by any shareholder of the Funds during regular business hours for ten days prior to the date of the Special Meetings.

In the absence of a quorum for a particular matter, business may proceed on any other matter or matters which may properly come before the Special Meeting if there shall be present, in person or by proxy, a quorum of shareholders in respect of such other matters. The chairman of the meeting may, whether or not a quorum is present, propose one or more adjournments of the Special Meeting on behalf of a Fund without further notice to permit further solicitation of proxies. Any such adjournment will require the affirmative vote of the holders of a majority of the shares of the Fund present in person or by proxy and entitled to vote at the session of the Special Meeting to be adjourned.

Broker-dealer firms holding shares in “street name” for the benefit of their customers and clients will request the instruction of such customers and clients on how to vote their shares on the proposals. A broker-dealer firm that has not received instructions from a customer prior to the date specified in its request for voting instructions may not vote such customer’s shares on the proposals. A signed proxy card or other authorization by a beneficial owner of shares of a Fund that does not specify how the beneficial owner’s shares are to be voted on a proposal may be deemed to be an instruction to vote such shares in favor of the proposal.

IF YOU CANNOT BE PRESENT AT THE MEETING, YOU ARE REQUESTED TO FILL IN, SIGN AND RETURN THE ENCLOSED PROXY PROMPTLY. NO POSTAGE IS REQUIRED IF MAILED IN THE UNITED STATES.

APPENDIX A

FORM OF AGREEMENT AND PLAN OF REORGANIZATION

THIS AGREEMENT AND PLAN OF REORGANIZATION (the “Agreement”) is made as of this day of , 2012 by and among Nuveen AMT-Free Municipal Income Fund, a Massachusetts business trust (the “Acquiring Fund”), and each of Nuveen Premier Municipal Opportunity Fund, Inc., a Minnesota corporation (“Premier Opportunity” or an “Acquired Fund”), and Nuveen Premium Income Municipal Opportunity Fund, a Massachusetts business trust (“Premium Opportunity” or an “Acquired Fund” and together with Premier Opportunity, the “Acquired Funds” ). The Acquiring Fund and each Acquired Fund may be referred to herein each as a “Fund” and collectively as the “Funds.”

For each Reorganization (as defined below), this Agreement is intended to be, and is adopted as, a plan of reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and the Treasury Regulations promulgated thereunder. The reorganization of each Acquired Fund into the Acquiring Fund will consist of: (i) the transfer of substantially all of the assets of the Acquired Fund to the Acquiring Fund in exchange solely for newly issued common shares, par value $0.01 per share, of the Acquiring Fund (“Acquiring Fund Common Shares”) and newly issued Variable Rate Demand Preferred Shares (“VRDP Shares”) of the Acquiring Fund, with a par value of $0.01 per share and liquidation preference of $100,000 per share, as set forth in this Agreement (“Acquiring Fund VRDP Shares” and together with the Acquiring Fund Common Shares, the “Acquiring Fund Shares”) and the assumption by the Acquiring Fund of substantially all of the liabilities of the Acquired Fund; and (ii) the distribution of all the Acquiring Fund Common Shares and Acquiring Fund VRDP Shares to the holders of common shares and VRDP Shares of the Acquired Fund, respectively, as part of the termination, dissolution and complete liquidation of the Acquired Fund as provided herein, all upon the terms and conditions set forth in this Agreement (each, a “Reorganization” and together, the “Reorganizations”).

WHEREAS, each Fund is a closed-end, management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”), and each Acquired Fund owns securities that generally are assets of the character in which the Acquiring Fund is permitted to invest;

WHEREAS, the Acquiring Fund is authorized to issue the Acquiring Fund Shares; and

WHEREAS, the Board of Trustees of the Acquiring Fund (the “Acquiring Fund Board”) has determined that the Reorganizations are in the best interests of the Acquiring Fund and that the interests of the existing shareholders of the Acquiring Fund will not be diluted as a result of the Reorganizations, and the Board of Trustees or Directors, as applicable, of each Acquired Fund (each, an “Acquired Fund Board”) has determined that the applicable Reorganization is in the best interests of the respective Acquired Fund and that the interests of the existing shareholders of such Acquired Fund will not be diluted as a result of its Reorganization.

NOW, THEREFORE, in consideration of the premises and of the covenants and agreements hereinafter set forth, the parties hereto covenant and agree as follows:

ARTICLE I

TRANSFER OF ASSETS OF EACH ACQUIRED FUND IN EXCHANGE FOR

ACQUIRING FUND SHARES AND THE ASSUMPTION OF THE LIABILITIES OF

EACH ACQUIRED FUND AND TERMINATION AND LIQUIDATION OF EACH

ACQUIRED FUND

1.1 THE EXCHANGE. Subject to the terms and conditions contained herein and on the basis of the representations and warranties contained herein, each Acquired Fund agrees to transfer substantially all of its assets, as set forth in Section 1.2, to the Acquiring Fund. In consideration therefor, the Acquiring Fund agrees: (i) to issue and deliver to such Acquired Fund the number of Acquiring Fund Common Shares computed in the manner set forth in Section 2.3, and the same number of Acquiring Fund VRDP Shares as the number of VRDP Shares of such Acquired Fund outstanding immediately prior to the Closing Date (less any VRDP Shares with respect to which Dissenters’ Rights, as defined below, have been properly exercised) and having substantially similar terms to such Acquired Fund’s VRDP Shares as of the Closing Date, and (ii) to assume substantially all of the liabilities of such Acquired Fund, if any, as set forth in Section 1.3. The Acquiring Fund VRDP Shares to be issued to each Acquired Fund shall consist of a separate series, as set forth in Exhibit A hereto, and each such series shall: (i) have equal priority with each other and with other outstanding preferred shares of the Acquiring Fund as to the payment of dividends and as to the distribution of assets upon liquidation of the Acquiring Fund; and (ii) have, along with any other outstanding preferred shares of the Acquiring Fund, preference with respect to the payment of dividends and as to the distribution of assets upon liquidation of the affairs of the Acquiring Fund over the Acquiring Fund Common Shares. Such transactions shall take place at the closing provided for in Section 3.1 (each a “Closing” and together, the “Closings”).

1.2 ASSETS TO BE TRANSFERRED. Each Acquired Fund shall transfer substantially all of its assets to the Acquiring Fund, including, without limitation, cash, securities, commodities, interests in futures, dividends or interest receivables owned by the Acquired Fund and any deferred or prepaid expenses shown as an asset on the books of the Acquired Fund as of the Valuation Time, as such term is defined in Section 2.1, except that the Acquired Fund shall retain assets sufficient to pay the preferred share dividends as set forth in Section 1.4, the dividends set forth in Section 8.5, and with respect to Premier Opportunity (the “MN Acquired Fund”), all liabilities (whether absolute, accrued, contingent or otherwise) as such Acquired Fund Board or its officers reasonably expect to exist against the MN Acquired Fund as a result of the exercise of dissenters’ rights under Minnesota law (“Dissenters’ Rights”).

Each Acquired Fund will, within a reasonable period of time before the Closing Date, furnish the Acquiring Fund with a list of the Acquired Fund’s portfolio securities and other investments. The Acquiring Fund will, within a reasonable period of time before the Closing Date, furnish each Acquired Fund with a list of the securities, if any, on the Acquired Fund’s list referred to above that do not conform to the Acquiring Fund’s investment objectives, policies, and restrictions. Each Acquired Fund, if requested by the Acquiring Fund, will dispose of securities on the Acquiring Fund’s list before the Closing Date. In addition, if it is determined that the portfolios of each Acquired Fund and the Acquiring Fund, when aggregated, would contain investments exceeding certain percentage limitations

A-2

imposed upon the Acquiring Fund with respect to such investments, each Acquired Fund, if requested by the Acquiring Fund, will dispose of a sufficient amount of such investments as may be necessary to avoid violating such limitations as of the Closing Date. Notwithstanding the foregoing, nothing herein will require any Acquired Fund to dispose of any investments or securities if, in the reasonable judgment of the Acquired Fund Board or Nuveen Fund Advisors, Inc., the investment adviser to the Funds (the “Adviser”), such disposition would adversely affect the status of its Reorganization as a “reorganization” as such term is used in the Code or would otherwise not be in the best interests of such Acquired Fund.

1.3 LIABILITIES TO BE ASSUMED. Each Acquired Fund will endeavor to discharge all of its known liabilities and obligations to the extent possible before the Closing Date, except for the dividends set forth in Section 1.4 and the dividends set forth in Section 8.5. Notwithstanding the foregoing, the liabilities not so discharged shall be assumed by the Acquiring Fund, which assumed liabilities shall include all of an Acquired Fund’s liabilities, debts, obligations, and duties of whatever kind or nature, whether absolute, accrued, contingent, or otherwise, whether or not arising in the ordinary course of business, whether or not determinable at the Closing Date, and whether or not specifically referred to in this Agreement, provided that the Acquiring Fund shall not assume any liabilities with respect to the dividends set forth in Section 1.4, the dividends set forth in Section 8.5, or any liabilities relating to the exercise of Dissenters’ Rights by shareholders of the MN Acquired Fund.

1.4 DECLARATION OF PREFERRED SHARE DIVIDENDS. Dividends shall accumulate on the preferred shares of each Acquired Fund up to and including the day before the Closing Date (as such term is defined in Section 3.1) and then cease to accumulate, and dividends on the Acquiring Fund VRDP Shares shall accumulate from and including the Closing Date. Prior to the Valuation Time, each Acquired Fund shall declare all accumulated but unpaid dividends on its Acquired Fund VRDP Shares up to and including the day before the Closing Date, such dividends shall be paid on the Closing Date to holders thereof on the day immediately preceding the Closing Date. Each Acquired Fund shall retain assets in an amount sufficient to pay the dividends declared by it pursuant to this Section 1.4, and such assets shall not be transferred to the Acquiring Fund on the Closing Date.

1.5 LIQUIDATION AND DISTRIBUTION. On or as soon after the Closing Date as is practicable but in no event later than 12 months after the Closing Date (the “Liquidation Date”): (a) each Acquired Fund will distribute in complete liquidation of the Acquired Fund, pro rata to its common shareholders of record, determined as of the Valuation Time, (the “Acquired Fund Common Shareholders”), all of the Acquiring Fund Common Shares received by such Acquired Fund pursuant to Section 1.1 (together with any dividends declared with respect thereto to holders of record as of a time after the Valuation Time and prior to the Liquidation Date (“Interim Dividends”)) and to its preferred shareholders of record, determined as of the Valuation Time, other than such holders of VRDP Shares of the MN Acquired Fund who have properly exercised Dissenters’ Rights with respect to the Reorganization (“Acquired Fund Preferred Shareholders” and, collectively with each Acquired Fund Common Shareholders, the “Acquired Fund Shareholders”), one share of Acquiring Fund VRDP Shares received by such Acquired Fund (together with any Interim Dividends) in exchange for each Acquired Fund VRDP Share held by such preferred shareholders of such Acquired Fund immediately prior to its respective Reorganization; and (b) each Acquired Fund will thereupon proceed to dissolve and terminate as set forth in Section 1.8 below. Such distribution will be accomplished by the transfer of the Acquiring Fund Shares then credited to the account of each Acquired Fund on the books of the Acquiring Fund to open accounts on the share records of the Acquiring Fund in the names of Acquired Fund Shareholders and representing, in the case of an Acquired Fund Common Shareholder, such

A-3

shareholder’s pro rata share of the Acquiring Fund Common Shares received by such Acquired Fund and in the case of an Acquired Fund Preferred Shareholder, a number of Acquiring Fund VRDP Shares received by such Acquired Fund equal to the number of Acquired Fund VRDP Shares held by such shareholder immediately prior to the Closing Date (as set forth above), and by paying to the shareholders of the Acquired Fund any Interim Dividends on such transferred shares. All issued and outstanding common and preferred shares of each Acquired Fund, including, without limitation, any VRDP Shares with respect to which Dissenters’ Rights have been properly exercised, will simultaneously be canceled on the books of the Acquired Fund. The Acquiring Fund shall not issue certificates representing Acquiring Fund Shares in connection with such transfer.

1.6 OWNERSHIP OF SHARES. Ownership of Acquiring Fund Shares will be shown on the books of the Acquiring Fund’s transfer agent. Acquiring Fund Shares will be issued simultaneously to each Acquired Fund, in an amount computed in the manner set forth in this Agreement, to be distributed to Acquired Fund Shareholders.

1.7 TRANSFER TAXES. Any transfer taxes payable upon the issuance of Acquiring Fund Shares in a name other than the registered holder of an Acquired Fund’s common shares or preferred shares on the books of such Acquired Fund as of that time shall, as a condition of such issuance and transfer, be paid by the person to whom such Acquiring Fund Shares are to be issued and transferred.

1.8 TERMINATION. Each Acquired Fund shall completely liquidate and be dissolved, terminated and have its affairs wound up in accordance with Massachusetts or Minnesota state law, as applicable, promptly following the Closing Date and the making of all distributions pursuant to Section 1.5.

1.9 REPORTING. Any reporting responsibility of each Acquired Fund including, without limitation, the responsibility for filing of regulatory reports, tax returns or other documents with the Securities and Exchange Commission (the “Commission”), the exchange on which such Acquired Fund’s shares are listed or any state securities commission and any federal, state or local tax authorities or any other relevant regulatory authority, is and shall remain the responsibility of such Acquired Fund.

1.10 BOOKS AND RECORDS. All books and records of each Acquired Fund, including all books and records required to be maintained under the 1940 Act, and the rules and regulations thereunder, shall be available to the Acquiring Fund from and after the Closing Date and shall be turned over to the Acquiring Fund as soon as practicable following the Closing Date.

ARTICLE II

VALUATION

2.1 VALUATION OF ASSETS. The value of the net assets of each Acquired Fund shall be the value of its assets, less its liabilities, computed as of the close of regular trading on the NYSE on the business day immediately prior to the Closing Date (such time and date being hereinafter called the “Valuation Time”), using the valuation procedures of the Nuveen closed-end funds adopted by the Acquired Fund Board or such other valuation procedures as shall be mutually agreed upon by the

A-4

parties. The value of each Acquired Fund’s net assets shall be calculated net of the liquidation preference (including accumulated and unpaid dividends) of all outstanding preferred shares of such Acquired Fund.

2.2 VALUATION OF SHARES. The net asset value per Acquiring Fund Common Share shall be computed as of the Valuation Time, using the valuation procedures of the Nuveen closed-end funds adopted by the Acquiring Fund Board or such other valuation procedures as shall be mutually agreed upon by the parties. The value of the Acquiring Fund’s net assets shall be calculated net of the liquidation preference (including accumulated and unpaid dividends) of all outstanding Acquiring Fund preferred shares.

2.3 COMMON SHARES TO BE ISSUED. The number of Acquiring Fund Common Shares to be issued in exchange for an Acquired Fund’s assets transferred to the Acquiring Fund shall be determined by dividing the value of such assets transferred to the Acquiring Fund (net of the liabilities of such Acquired Fund that are assumed by the Acquiring Fund) determined in accordance with Section 2.1, by the net asset value of an Acquiring Fund Common Share determined in accordance with Section 2.2. No fractional Acquiring Fund Common Shares will be issued to an Acquired Fund’s shareholders and, in lieu of such fractional shares, an Acquired Fund’s shareholders will receive cash. The aggregate net asset value of Acquiring Fund Common Shares received by each Acquired Fund in a Reorganization will equal, as of the Valuation Time, the aggregate net asset value of Acquired Fund common shares held by shareholders of such Acquired Fund as of such time. In the event there are fractional Acquiring Fund Common Shares due an Acquired Fund shareholder on the Closing Date after each Acquired Fund’s assets have been exchanged for Acquiring Fund Common Shares, the Acquiring Fund’s transfer agent will aggregate such fractional common shares and sell the resulting whole on the exchange on which such shares are listed for the account of holders of all such fractional interests, and each such holder will be entitled to a pro rata share of the proceeds from such sale. With respect to the aggregation and sale of fractional common shares, the Acquiring Fund’s transfer agent will act directly on behalf of the shareholders entitled to receive fractional shares and will accumulate such fractional shares, sell the shares and distribute the cash proceeds net of brokerage commissions, if any, directly to shareholders entitled to receive the fractional shares (without interest and subject to withholding taxes).

2.4 EFFECT OF SUSPENSION IN TRADING. In the event that at the Valuation Time, either: (a) the exchange on which shares of a Fund are listed or another primary exchange on which the portfolio securities of the Acquiring Fund or an Acquired Fund are purchased or sold shall be closed to trading or trading on such exchange shall be restricted; or (b) trading or the reporting of trading on the exchange on which shares of a Fund are listed or elsewhere shall be disrupted so that accurate appraisal of the value of the net assets of the Acquiring Fund or an Acquired Fund is impracticable, the Valuation Time shall be postponed until the first business day after the day when trading is fully resumed and reporting is restored.

2.5 COMPUTATIONS OF NET ASSETS. All computations of net asset value in this Article II shall be made by or under the direction of State Street Bank and Trust Company (“State Street”) in accordance with its regular practice as custodian of the Funds.

(b) The Acquiring Fund shall issue and deliver or cause State Street and The Bank of New York Mellon in their capacities as transfer agent with respect to common shares and tender and paying agent with respect to VRDP Shares, respectively, to issue and deliver to each Acquired Fund a confirmation evidencing the Acquiring Fund Shares to be credited on the Closing Date to the Secretary of each Acquired Fund or provide evidence satisfactory to each Acquired Fund that such Acquiring Fund Shares have been credited to each Acquired Fund’s account on the books of the Acquiring Fund.

periods ending on or before the Closing Date (computed without regard to any deduction for dividends paid), if any, plus the excess of its interest income excludible from gross income under Section 103(a) of the Code, if any, over its deductions disallowed under Sections 265 and 171(a)(2) of the Code for all taxable periods ending on or before the Closing Date and all of its net capital gains realized in all taxable periods ending on or before the Closing Date (after reduction for any available capital loss carry forward).

8.6 The Acquired Funds shall have received on the Closing Date an opinion from Vedder Price P.C. dated as of the Closing Date, substantially to the effect that:

(a) The Acquiring Fund has been formed as a voluntary association with transferable shares of beneficial interest commonly referred to as a “Massachusetts business trust,” and is existing under the laws of the Commonwealth of Massachusetts and, to such counsel’s knowledge, has the power as a business trust to own all of its properties and assets and to carry on its business as presently conducted, in each case as described in the Joint Proxy Statement/Prospectus.

(b) The Acquiring Fund is registered as a closed-end management investment company under the 1940 Act, and, to such counsel’s knowledge, such registration under the 1940 Act is in full force and effect.

(c) Assuming that the Acquiring Fund Shares will be issued in accordance with the terms of this Agreement, the Acquiring Fund Shares to be issued and delivered to each Acquired Fund on behalf of its Acquired Fund Shareholders as provided by this Agreement are duly authorized and, upon such delivery, will be validly issued and fully paid and non-assessable by the Acquiring Fund except that, as described in the Registration Statement, shareholders of the Acquiring Fund may, under certain circumstances, be held personally liable for its obligations, and no shareholder of the Acquiring Fund has, as such holder, any preemptive rights to acquire, purchase or subscribe for any securities of the Acquiring Fund under the Acquiring Fund’s Declaration of Trust, By-Laws or Massachusetts law.

(d) The Registration Statement is effective and, to such counsel’s knowledge, no stop order under the 1933 Act pertaining thereto has been issued.

(e) To the knowledge of such counsel, no consent, approval, authorization or order of any court or governmental authority of the United States or the Commonwealth of Massachusetts is required for consummation by the Acquiring Fund of the transactions contemplated herein, except as have been obtained.

(f) The execution and delivery of the Agreement by the Fund, did not, and the consummation by the Acquiring Fund of the transactions contemplated herein will not, violate the Acquiring Fund’s Declaration of Trust, MTP Statement or By-Laws (assuming the requisite approval of the Fund’s shareholders has been obtained in accordance with its Declaration of Trust, MTP Statement and By-Laws).

Insofar as the opinions expressed above relate to or are dependent on matters governed by the laws of the Commonwealth of Massachusetts, Vedder Price P.C. may rely on the opinion of Bingham McCutchen LLP.

8.7 The Acquiring Fund shall have received on the Closing Date an opinion from Vedder Price P.C. dated as of the Closing Date, substantially to the effect that:

(a) Premium Opportunity has been formed as a voluntary association with transferable shares of beneficial interest commonly referred to as a “Massachusetts business trust,” and

A-14

is existing under the laws of the Commonwealth of Massachusetts and, to such counsel’s knowledge, has the power as a business trust to own all of its properties and assets and to carry on its business as presently conducted, in each case as described in the Joint Proxy Statement/Prospectus.

(b) Premier Opportunity has been duly incorporated and is validly existing and in good standing under the laws of the State of Minnesota and, to such counsel’s knowledge, has the power to own all of its properties and assets and to carry on its business as presently conducted, in each case as described in the Joint Proxy Statement/Prospectus.

(c) Each Acquired Fund is registered as a closed-end management investment company under the 1940 Act, and, to such counsel’s knowledge, such registration under the 1940 Act is in full force and effect.

(d) To the knowledge of such counsel, no consent, approval, authorization or order of any court or governmental authority of the United States or the Commonwealth of Massachusetts or State of Minnesota, as applicable, is required for consummation by the Acquired Funds of the transactions contemplated herein, except as have been obtained.

(e) With respect to each Acquired Fund, the execution and delivery of the Agreement by the Acquired Fund, did not, and the consummation by the Acquired Fund of the transactions contemplated herein will not, violate the Acquired Fund’s Declaration of Trust or Articles of Incorporation, as applicable, VRDP Statement or By-Laws (assuming the requisite approval of the Fund’s shareholders has been obtained in accordance with its Declaration of Trust or Articles of Incorporation, as applicable, VRDP Statement and By-Laws).

Insofar as the opinions expressed above relate to or are dependent upon matters governed by the laws of the Commonwealth of Massachusetts, Vedder Price P.C. may rely on the opinion of Bingham McCutchen LLP. Insofar as the opinions expressed above relate to or are dependent upon matters governed by the laws of or the State of Minnesota, Vedder Price P.C. may rely on the opinion of Dorsey & Whitney LLP.

8.8 With respect to each Reorganization, the Funds participating in such Reorganization shall have received an opinion of Vedder Price P.C. addressed to the Acquiring Fund and the Acquired Fund substantially to the effect that for federal income tax purposes:

(a) The transfer of substantially all of the Acquired Fund’s assets to the Acquiring Fund in exchange solely for Acquiring Fund Shares and the assumption by the Acquiring Fund of substantially all of the liabilities of the Acquired Fund followed by the distribution to Acquired Fund Shareholders of all the Acquiring Fund Shares received by the Acquired Fund in complete liquidation of the Acquired Fund will constitute a “reorganization” within the meaning of Section 368(a) of the Code and the Acquiring Fund and the Acquired Fund will each be a “party to a reorganization,” within the meaning of Section 368(b) of the Code, with respect to the Reorganization.

(b) No gain or loss will be recognized by the Acquiring Fund upon the receipt of substantially all of the assets of the Acquired Fund solely in exchange for Acquiring Fund Shares and the assumption by the Acquiring Fund of substantially all of the liabilities of the Acquired Fund.

(c) No gain or loss will be recognized by the Acquired Fund upon the transfer of substantially all of its assets to the Acquiring Fund solely in exchange for Acquiring Fund Shares and the assumption by the Acquiring Fund of substantially all of the liabilities of the Acquired Fund or

A-15

upon the distribution (whether actual or constructive) of such Acquiring Fund Shares to Acquired Fund Shareholders solely in exchange for such shareholders’ common and preferred shares of the Acquired Fund in complete liquidation of the Acquired Fund.

(d) No gain or loss will be recognized by the Acquired Fund Shareholders upon the exchange of their Acquired Fund shares solely for Acquiring Fund Shares in the Reorganization, except with respect to any cash received in lieu of a fractional Acquiring Fund Common Share.

(e) The aggregate basis of the Acquiring Fund Shares received by each Acquired Fund Shareholder pursuant to the Reorganization (including any fractional Acquiring Fund Common Share to which a shareholder would be entitled) will be the same as the aggregate basis of the Acquired Fund shares exchanged therefor by such shareholder. The holding period of the Acquiring Fund Shares received by each Acquired Fund Shareholder (including any fractional Acquiring Fund Common Share to which a shareholder would be entitled) will include the period during which the Acquired Fund shares exchanged therefor were held by such shareholder, provided such Acquired Fund shares are held as capital assets at the time of the Reorganization.

(f) The basis of the Acquired Fund’s assets transferred to the Acquiring Fund will be the same as the basis of such assets to the Acquired Fund immediately before the Reorganization. The holding period of the assets of the Acquired Fund in the hands of the Acquiring Fund will include the period during which those assets were held by the Acquired Fund.

No opinion will be expressed as to (1) the federal income tax consequences of payments, if any, to preferred shareholders of the MN Acquired Fund who elect Dissenters’ Rights, (2) the effect of the Reorganizations on (A) each Acquired Fund, the Acquiring Fund or any Acquired Fund Shareholder with respect to any asset as to which any unrealized gain or loss is required to be recognized under federal income tax principles (i) at the end of a taxable year (or on the termination thereof) or (ii) upon the transfer of such asset regardless of whether such transfer would otherwise be a non-taxable transaction under the Code, or (B) an Acquired Fund, the Acquiring Fund or any Acquired Fund Shareholder with respect to any stock held in a passive foreign investment company as defined in Section 1297(a) of the Code or (2) any other federal tax issues (except those set forth above) and all state, local or foreign tax issues of any kind.

Such opinion shall be based on customary assumptions and such representations as Vedder Price P.C. may reasonably request of the Funds, and each Acquired Fund and the Acquiring Fund will cooperate to make and certify the accuracy of such representations. Notwithstanding anything herein to the contrary, neither the Acquiring Fund nor any Acquired Fund may waive the conditions set forth in this Section 8.8. Insofar as the opinions expressed above relate to or are dependent upon the classification of the Acquiring Fund VRDP Shares as equity securities for U.S. federal income tax purposes, Vedder Price P.C. may rely on the opinion of Sidley Austin LLP with respect to such issue.

8.9 The Acquiring Fund shall have obtained written confirmation from Moody’s Investors Service, Inc., Fitch, Inc. or Standard & Poor’s Ratings Services, as applicable, that (a) consummation of the transactions contemplated by this Agreement will not impair the then current rating assigned by such rating agencies to the existing Acquiring Fund MTP Shares and VMTP Shares and (b) the Acquiring Fund VRDP Shares to be issued pursuant to Section 1.1 will be rated by such rating agencies no less than the then current rating assigned by such rating agencies to the Acquired Fund VRDP Shares exchanged therefor.

(a) | The amounts shown are based on common share equivalents.

(b) | Total Return Based on Market Value is the combination of changes in the market price per share and the effect of reinvested dividend income and reinvested capital gains distributions, if any, at the average price paid per share at the time of reinvestment. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last dividend declared in the period may take place over several days, and in some instances may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation. Total returns are not annualized.

| Total Return Based on Common Share Net Asset Value is the combination of changes in common share net asset value, reinvested dividend income at net asset value and reinvested capital gains distributions at net asset value, if any. The last dividend declared in the

B-2

| period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending net asset value. The actual reinvest price for the last dividend declared in the period may often be based on the Fund’s market price (and not its net asset value), and therefore may be different from the price used in the calculation. Total returns are not annualized.

(c) | Ratios do not reflect the effect of dividend payments to Auction Rate Preferred shareholders, where applicable; Net Investment Income (Loss) ratios reflect income earned and expenses incurred on assets attributable to ARPS, MTP Shares and/or VMTP Shares, where applicable.

(d) | After expense reimbursement from the Adviser, where applicable. Ratios do not reflect the effect of custodian fee credits earned on the Fund’s net cash on deposit with the custodian bank or legal fee refund, where applicable. As of November 30, 2010, the Adviser is no longer reimbursing the Fund for any fees or expenses.

(e) | The expense ratios reflect, among other things, all interest expense and other costs related to MTP Shares, VMTP Shares and/or the interest expense deemed to have been paid by the Fund on the floating rate certificates issued by the special purpose trusts for the self-deposited inverse floaters held by the Fund, where applicable, each as described in Footnote 1—General Information and Significant Accounting Policies, MuniFund Term Preferred Shares, Variable Rate MuniFund Preferred Shares and Inverse Floating Rate Securities, respectively, in the most recent shareholder report, as follows:

(a) | The amounts shown are based on common share equivalents.

(b) | Total Return Based on Market Value is the combination of changes in the market price per share and the effect of reinvested dividend income and reinvested capital gains distributions, if any, at the average price paid per share at the time of reinvestment. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last dividend declared in the period may take place over several days, and in some instances may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation. Total returns are not annualized.

| Total Return Based on Common Share Net Asset Value is the combination of changes in common share net asset value, reinvested dividend income at net asset value and reinvested capital gains distributions at net asset value, if any. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending net asset value. The actual reinvest price for the last dividend declared in the period may often be based on the Fund’s market price (and not its net asset value), and therefore may be different from the price used in the calculation. Total returns are not annualized.

(c) | Ratios do not reflect the effect of dividend payments to Auction Rate Preferred shareholders, where applicable; Net Investment Income (Loss) ratios reflect income earned and expenses incurred on assets attributable to ARPS and/or VRDP Shares, where applicable.

(d) | Ratios do not reflect the effect of custodian fee credits earned on the Fund’s net cash on deposit with the custodian bank or legal fee refund, where applicable.

(e) | The expense ratios reflect, among other things, all interest expense and other costs related to VRDP Shares and/or the interest expense deemed to have been paid by the Fund on the floating rate certificates issued by the special purpose trusts for the self-deposited inverse floaters held by the Fund, both as described in Footnote 1—General Information and Significant Accounting Policies, Variable Rate Demand Preferred Shares and Inverse Floating Rate Securities, respectively, in the most recent shareholder report, as follows:

GENERAL

Effective January 2, 2012, the Acquiring Fund changed its name from “Nuveen Insured Tax-Free Advantage Municipal Fund” to “Nuveen AMT-Free Municipal Income Fund.”

INVESTMENT OBJECTIVES AND POLICIES

The following supplements the information contained in the Joint Proxy Statement/Prospectus concerning the investment objectives and policies of the Funds. The investment policies described below, except as set forth under “Investment Restrictions,” are not fundamental policies and may be changed by a Fund’s Board of Trustees or Board of Directors, as applicable, without the approval of shareholders.

Under normal circumstances, the Acquiring Fund will invest at least 80% of its net assets, including assets attributable to any principal amount of any borrowings (including the issuance of commercial paper or notes) or any preferred shares outstanding (“Managed Assets”) in portfolio securities that pay interest exempt from regular federal income tax and from the federal alternative minimum tax applicable to individuals (the “AMT”). Under normal circumstances, each Acquired Fund will invest at least 80% of its Managed Assets in a portfolio of securities that pay interest exempt from regular federal income taxes.

Under normal circumstances, each Fund invests at least 80% of its managed assets in investment grade securities that, at the time of investment, are rated within the four highest grades (Baa or BBB or better) by at least one nationally recognized statistical ratings organization (“NRSRO”) or are unrated but judged to be of comparable quality by the Adviser. Each Fund may invest up to 20% of its managed assets in municipal securities that at the time of investment are rated below investment grade or are unrated but judged to be of comparable quality by the Adviser. No more than 10% of each Fund’s managed assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by the Adviser.

If a municipal security satisfies the rating requirements described above at the time of purchase, a Fund will not be required to dispose of the security upon downgrade.

Each Fund also may invest up to 15% of its net assets in inverse floating rate securities.

During temporary defensive periods and in order to keep each Fund’s cash fully invested, a Fund may invest up to 100% of its net assets in short-term investments including high-quality, short-term securities that may be either tax exempt or taxable. Each Fund intends to invest in taxable short-term investments only in the event that suitable tax-exempt short-term investments are not available at reasonable prices and yields. Investment in taxable short-term investments would result in a portion of your dividends being subject to regular federal income tax.

A general description of NRSRO (i.e., Moody’s, S&P and Fitch) ratings of municipal securities is set forth in Appendix A to this Statement of Additional Information.

PORTFOLIO COMPOSITION

In addition to and supplementing the Joint Proxy Statement/Prospectus, each Fund’s portfolio will be composed principally of the investments described below.

General. Each Fund may invest in various municipal securities, including municipal bonds and notes, other securities issued to finance and refinance public projects, and other related securities and derivative instruments creating exposure to municipal bonds, notes and securities that provide for the payment of interest income that is exempt from regular federal income taxes (and, in the case of the Acquiring Fund, the federal alternative minimum tax applicable to individuals). Municipal securities are generally debt obligations issued by state and local governmental entities and may be issued by U.S. territories to finance or refinance public projects such as roads, schools, and water supply systems. Municipal securities may also be issued for private activities, such as housing, medical and educational facility construction, or for privately owned transportation, electric utility and pollution control projects. Municipal securities may be issued on a long term basis to provide permanent financing. The repayment of such debt may be secured generally by a pledge of the full faith and credit taxing power of the issuer, a limited or special tax, or any other revenue source including project revenues, which may include tolls, fees and other user charges, lease payments, and mortgage payments. Municipal securities may also be issued to finance projects on a short term interim basis, anticipating repayment with the proceeds on long term debt. Municipal securities may be issued and purchased in the form of bonds, notes, leases or certificates of participation; structured as callable or non-callable; with payment forms including fixed coupon, variable rate, zero coupon, capital appreciation bonds, tender option bonds, and residual interest bonds or inverse floating rate securities; or acquired through investments in pooled vehicles, partnerships or other investment companies. Inverse floating rate securities are securities that pay interest at rates that vary inversely with changes in prevailing short-term tax-exempt interest rates and represent a leveraged investment in an underlying municipal security, which may increase the effective leverage of the Fund.

The yields on municipal securities depend on a variety of factors, including prevailing interest rates and the condition of the general money market and the municipal bond market, the size of a particular offering, the maturity of the obligation and the rating of the issue. The market value of municipal bonds will vary with changes in interest rate levels and as a result of changing evaluations of the ability of their issuers to meet interest and principal payments.

Municipal Leases and Certificates of Participation. The Funds also may purchase municipal securities that represent lease obligations and certificates of participation in such leases. These carry special risks because the issuer of the securities may not be obligated to appropriate money annually to make payments under the lease. A municipal lease is an obligation in the form of a lease or installment purchase that is issued by a state or local government to acquire equipment and facilities. Income from such obligations generally is exempt from state and local taxes in the state of issuance. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of “non-appropriation” clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body on a yearly or other periodic basis. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event the issuer is prevented

S-2

from maintaining occupancy of the leased premises or utilizing the leased equipment or facilities. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and result in a delay in recovering, or the failure to recover fully, a Fund’s original investment. To the extent that a Fund invests in unrated municipal leases or participates in such leases, the credit quality rating and risk of cancellation of such unrated leases will be monitored on an ongoing basis. In order to reduce this risk, the Funds will only purchase municipal securities representing lease obligations where the Adviser believes the issuer has a strong incentive to continue making appropriations until maturity.

A certificate of participation represents an undivided interest in an unmanaged pool of municipal leases, an installment purchase agreement or other instruments. The certificates typically are issued by a municipal agency, a trust or other entity that has received an assignment of the payments to be made by the state or political subdivision under such leases or installment purchase agreements. Such certificates provide the Funds with the right to a pro rata undivided interest in the underlying municipal securities. In addition, such participations generally provide the Funds with the right to demand payment, on not more than seven days’ notice, of all or any part of a Fund’s participation interest in the underlying municipal securities, plus accrued interest.

Municipal Notes. Municipal securities in the form of notes generally are used to provide for short-term capital needs, in anticipation of an issuer’s receipt of other revenues or financing, and typically have maturities of up to three years. Such instruments may include tax anticipation notes, revenue anticipation notes, bond anticipation notes, tax and revenue anticipation notes and construction loan notes. Tax anticipation notes are issued to finance the working capital needs of governments. Generally, they are issued in anticipation of various tax revenues, such as income, sales, property, use and business taxes, and are payable from these specific future taxes. Revenue anticipation notes are issued in expectation of receipt of other kinds of revenue, such as federal revenues available under federal revenue sharing programs. Bond anticipation notes are issued to provide interim financing until long-term bond financing can be arranged. In most cases, the long-term bonds then provide the funds needed for repayment of the bond anticipation notes. Tax and revenue anticipation notes combine the funding sources of both tax anticipation notes and revenue anticipation notes. Construction loan notes are sold to provide construction financing. Mortgage notes insured by the Federal Housing Authority secure these notes; however, the proceeds from the insurance may be less than the economic equivalent of the payment of principal and interest on the mortgage note if there has been a default. The anticipated revenues from taxes, grants or bond financing generally secure the obligations of an issuer of municipal notes. An investment in such instruments, however, presents a risk that the anticipated revenues will not be received or that such revenues will be insufficient to satisfy the issuer’s payment obligations under the notes or that refinancing will be otherwise unavailable.

Pre-Refunded Municipal Securities. The principal of, and interest on, pre-refunded municipal securities are no longer paid from the original revenue source for the securities. Instead, the source of such payments is typically an escrow fund consisting of U.S. government securities. The assets in the escrow fund are derived from the proceeds of refunding bonds issued by the same issuer as the pre-refunded municipal securities. Issuers of municipal securities use this advance refunding technique to obtain more favorable terms with respect to securities that are not yet subject to call or redemption by the issuer. For example, advance refunding enables an issuer to refinance debt at lower market interest rates, restructure debt to improve cash flow or eliminate restrictive covenants in the indenture or other governing instrument for the pre-refunded municipal securities. However, except for a change

S-3

in the revenue source from which principal and interest payments are made, the pre-refunded municipal securities remain outstanding on their original terms until they mature or are redeemed by the issuer.

Private Activity Bonds. Private activity bonds are issued by or on behalf of public authorities to obtain funds to provide privately operated housing facilities, airport, mass transit or port facilities, sewage disposal, solid waste disposal or hazardous waste treatment or disposal facilities and certain local facilities for water supply, gas or electricity. Other types of private activity bonds, the proceeds of which are used for the construction, equipment, repair or improvement of privately operated industrial or commercial facilities, may constitute municipal securities, although the current federal tax laws place substantial limitations on the size of such issues. A Fund’s distributions of its interest income from private activity bonds may subject certain investors to the federal alternative minimum tax.

Special Taxing Districts. Special taxing districts are organized to plan and finance infrastructure developments to induce residential, commercial and industrial growth and redevelopment. The bond financing methods such as tax increment finance, tax assessment, special services district and Mello-Roos bonds, generally are payable solely from taxes or other revenues attributable to the specific projects financed by the bonds without recourse to the credit or taxing power of related or overlapping municipalities. They often are exposed to real estate development-related risks and can have more taxpayer concentration risk than general tax-supported bonds, such as general obligation bonds. Further, the fees, special taxes, or tax allocations and other revenues that are established to secure such financings generally are limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. The bonds could default if development failed to progress as anticipated or if larger taxpayers failed to pay the assessments, fees and taxes as provided in the financing plans of the districts.

The foregoing information constitutes only a brief summary of some of the general factors which may impact certain issuers of municipal bonds and does not purport to be a complete or exhaustive description of all adverse conditions to which the issuers of municipal bonds held by the Funds are subject. Additionally, many factors including national economic, social and environmental policies and conditions, which are not within the control of the issuers of the municipal bonds, could affect or could have an adverse impact on the financial condition of the issuers. The Funds are unable to predict whether or to what extent such factors or other factors may affect the issuers of the municipal bonds, the market value or marketability of the municipal bonds or the ability of the respective issuers of the municipal bonds acquired by the Funds to pay interest on or principal of the municipal bonds. This information has not been independently verified.

Derivatives and Hedging Strategies

The Funds may periodically engage in hedging transactions, and otherwise use various types of derivative instruments, described below, to reduce risk, to effectively gain particular market exposures, to seek to enhance returns, and to reduce transaction costs, among other reasons. In addition to inverse floating rate securities and structured notes, the Funds may invest in certain other derivative instruments in pursuit of its investment objectives. Such instruments include financial futures contracts, swap contracts (including interest rate and credit default swaps), options on financial futures, options on swap contracts or other derivative instruments whose prices, in the Adviser’s opinion, correlate with the prices of the Funds’ investments. The Adviser uses derivatives to shorten or lengthen the effective

S-4

duration of its portfolio securities, and therefore the interest rate risk, of the Funds’ portfolios, and to adjust other aspects of the portfolio’s risk/return profile. The Funds may use these instruments if the Funds deem it more efficient from a transaction cost, total return or income standpoint than investing in cash securities.

“Hedging” is a term used for various methods of seeking to preserve portfolio capital value by offsetting price changes in one investment through making another investment whose price should tend to move in the opposite direction.

A “derivative” is a financial contract whose value is based on (or “derived” from) a traditional security (such as a stock or a bond), an asset (such as a commodity like gold), or a market index (such as the Barclays Capital Municipal Bond Index). Some forms of derivatives may trade on exchanges, while non-standardized derivatives, which tend to be more specialized and complex, trade in “over-the-counter” or a one-on-one basis. It may be desirable and possible in various market environments to partially hedge the portfolio against fluctuations in market value due to market interest rate or credit quality fluctuations, or instead to gain a desired investment exposure, by entering into various types of derivative transactions, including financial futures and index futures as well as related put and call options on such instruments, structured notes, or interest rate swaps on taxable or tax-exempt securities or indexes (which may be “forward-starting”), credit default swaps, and options on interest rate swaps, among others.

These transactions present certain risks. In particular, the imperfect correlation between price movements in the futures contract and price movements in the securities being hedged creates the possibility that losses on the hedge by the Funds may be greater than gains in the value of the securities in the Funds’ portfolios. In addition, futures and options markets may not be liquid in all circumstances. As a result, in volatile markets, the Funds may not be able to close out the transaction without incurring losses substantially greater than the initial deposit. Losses due to hedging transactions will reduce the Funds’ net asset value which in turn could reduce yield. The Funds will not make any investment (whether an initial premium or deposit or a subsequent deposit) other than as necessary to close a prior investment if, immediately after such investment, the sum of the amount of its premiums and deposits would exceed 15% of a Fund’s Managed Assets. The Funds will invest in these instruments only in markets believed by the Adviser to be active and sufficiently liquid. Successful implementation of most hedging strategies would generate taxable income.

Both parties entering into an index or financial futures contract are required to post an initial deposit, typically equal to from 1% to 5% of the total contract price. Typically, option holders enter into offsetting closing transactions to enable settlement in cash rather than take delivery of the position in the future of the underlying security. Interest rate swap and credit default swap transactions are typically entered on a net basis, meaning that the two payment streams are netted out with the Funds receiving or paying, as the case may be, only the net amount of the two payments. The Funds will only sell covered futures contracts, which means that the Funds segregate assets equal to the amount of the obligations.

Interest Rate and Total Return Swaps. The Funds may invest in interest rate swaps, total return swaps and other debt-related derivative instruments. The Funds will enter into swap agreements only with counterparties that meet certain standards of creditworthiness. In an interest rate swap, the Funds and another party exchange their respective commitments to pay each other floating for fixed rates of interest at a floating rate referenced to local short-term interest rates and a fixed rate referenced

S-5

to the interest rate in the international (non-U.S.) local government securities market denominated in that non-U.S. market currency. In a total return swap, the Funds exchanges with another party their respective commitments to pay or receive the total return of an underlying asset and a floating local short-term interest rate.

The Funds usually will enter into interest rate swaps and total return swaps on a net basis (i.e., the two payment streams are netted out with the Funds receiving or paying, as the case may be, only the net amount of the two payments). The net amount of the excess, if any, of the Funds’ obligations over its entitlements with respect to each interest rate swap will be accrued on a daily basis, and an amount of cash or liquid securities having an aggregate net asset value at least equal to the accrued excess will be segregated by the Funds. If the interest rate swap transaction is entered into on other than a net basis, the full amount of the Funds’ obligations will be accrued on a daily basis, and the full amount of the Funds’ obligations will be segregated by the Funds.

The use of swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions, including the risk that the counterparty may be unable to fulfill the transaction. If there is a default by the other party to such a transaction, the Funds will have contractual remedies pursuant to the agreements related to the transaction. If the Adviser is incorrect in its forecasts of market values, interest rates and other applicable factors, the investment performance of the Funds would be unfavorably affected.

Credit Default Swaps. A credit default swap is an agreement between two counterparties, in which one party makes a periodic payment to the other party in exchange for a potential payoff if a third party (the “reference credit”) defaults in the payment of its debt obligations. The Funds may enter into a credit default swap as the first party (or “buyer”) seeking to receive credit protection to hedge a specific portfolio holding. In this example, a counterparty is the provider (or “seller”) of credit protection. Generally, credit default swaps may reference a specific entity or a pool of entities. The settlement of a credit default swap, upon the occurrence of a trigger event, may be accomplished by means of physical delivery of the securities of the reference entity, or a cash payment. Entering into credit default swap agreements involves counterparty risks.

Bond Futures and Forward Contracts. Bond futures contracts are agreements in which one party agrees to deliver to the other an amount of cash equal to a specific dollar amount times the difference between the value of a specific bond at the close of the last trading day of the contract and the price at which the agreement is made. No physical delivery of securities is made. Forward contracts are agreements to purchase or sell a specified security or currency at a specified future date (or within a specified time period) and price set at the time of the contract. Forward contracts are usually entered into with banks, foreign exchange dealers or broker-dealers and are usually for less than one year, but may be renewed. Forward contracts are generally purchased or sold in over-the-counter transactions.

Under regulations of the Commodity Futures Trading Commission (“CFTC”) currently in effect, which may change from time to time, with respect to futures contracts purchased by the Funds, the Funds will set aside in a segregated account liquid securities with a value at least equal to the value of instruments underlying such futures contracts less the amount of initial margin on deposit for such contracts. The current view of the staff of the Securities and Exchange Commission is that the Funds’ long and short positions in futures contracts must be collateralized with cash or certain liquid assets held in a segregated account or “covered” in order to counter the impact of any potential leveraging.

S-6

Parties to a futures contract must make “initial margin” deposits to secure performance of the contract. There are also requirements to make “variation margin” deposits from time to time as the value of the futures contract fluctuates.

Options on Currency Futures Contracts. Currency futures contracts are standardized agreements between two parties to buy and sell a specific amount of a currency at a set price on a future date. While similar to currency forward contracts, currency futures contracts are traded on commodities exchanges and are standardized as to contract size and delivery date. An option on a currency futures contract gives the holder of the option the right to buy or sell a position in a currency futures contract, at a set price and on or before a specified expiration date. Trading options on international (non-U.S.) currency futures contracts is relatively new. The ability to establish and close out positions on such options is subject to the maintenance of a liquid secondary market.

The Funds and the Adviser have claimed, respectively, an exclusion from registration as a commodity pool operator and as a commodity trading advisor under the Commodity Exchange Act (the “CEA”) and, therefore, neither the Funds, the Adviser, nor their officers and trustees, are subject to the registration requirements of the CEA or regulation as a commodity pool operator or a commodity trading advisor under the CEA. On February 9, 2012, the CFTC adopted amendments to its rules that, once effective, may affect the ability of the Funds to continue to claim the 4.5 exclusion. A Fund that seeks to claim the exclusion after the effectiveness of the amended rules would be limited in its ability to use futures and options on futures or commodities or engage in swap transactions. If the Funds were no longer able to claim the exclusion, the Adviser would be required to register as a “commodity pool operator,” and the Funds and the Adviser would be subject to regulation under the Commodity Exchange Act. The Funds reserve the right to engage in transactions involving futures and options thereon to the extent allowed by CFTC regulations in effect from time to time and in accordance with the Funds’ policies. In addition, certain provisions of the Internal Revenue Code of 1986, as amended (the “Code”), may limit the extent to which the Funds may enter into futures contracts or engage in options transactions. See “Federal Income Tax Matters.”

Index Futures. A tax-exempt bond index which assigns relative values to the tax-exempt bonds included in the index is traded on the Chicago Board of Trade. The index fluctuates with changes in the market values of all tax-exempt bonds included rather than a single bond. An index future is a bilateral agreement pursuant to which two parties agree to take or make delivery of an amount of cash—rather than any security—equal to a specified dollar amount times the difference between the index value at the close of the last trading day of the contract and the price at which the index future was originally written. Thus, an index future is similar to traditional financial futures except that settlement is made in cash.

Index Options. The Funds may also purchase put or call options on U.S. government or tax-exempt bond index futures and enter into closing transactions with respect to such options to terminate an existing position. Options on index futures are similar to options on debt instruments except that an option on an index future gives the purchaser the right, in return for the premium paid, to assume a position in an index contract rather than an underlying security at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance of the writer’s futures margin account which represents the amount by which the market price of the index futures contract, at exercise, is less than the exercise price of the option on the index future.

S-7

Bond index futures and options transactions would be subject to risks similar to transactions in financial futures and options thereon as described above.

Interest Rate Transactions. In order to seek to hedge the value of a Fund’s portfolio or to seek to increase the Fund’s return, the Fund may enter into various interest rate transactions such as interest rate swaps and the purchase or sale of interest rate caps and floors. Each Fund may enter into these transactions to seek to increase its return, to preserve a return or spread on a particular investment or portion of its portfolio, or to seek to protect against any increase in the price of securities the Fund anticipates purchasing at a later date.

Interest rate swaps involve a Fund’s agreement with the swap counterparty to pay a fixed rate payment in exchange for the counterparty agreeing to pay the Fund a payment at a variable rate that is expected to approximate the rate on the Fund’s variable rate payment obligations. The payment obligations would be based on the notional amount of the swap. The Funds may use an interest rate cap, which would require it to pay a premium to the cap counterparty and would entitle it, to the extent that a specified variable rate index exceeds a predetermined fixed rate, to receive from the counterparty payment of the difference based on the notional amount. The Funds would use interest rate swaps or caps only with the intent to reduce or eliminate the risk that an increase in short-term interest rates could have on common share net earnings as a result of leverage.

The Funds will usually enter into swaps or caps on a net basis; that is, the two payment streams will be netted out in a cash settlement on the payment date or dates specified in the instrument, with the Funds receiving or paying, as the case may be, only the net amount of the two payments. The Funds intend to maintain in a segregated account with its custodian cash or liquid securities having a value at least equal to a Fund’s net payment obligations under any swap transaction, marked-to-market daily.

The use of interest rate transactions, such as interest rate swaps and caps, is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. Depending on the state of interest rates in general, the Funds’ use of interest rate swaps or caps could enhance or harm the overall performance of a Fund’s common shares. To the extent there is a decline in interest rates, the value of the interest rate swap or cap could decline, and could result in a decline in the net asset value of the common shares. In addition, if short-term interest rates are lower than a Fund’s fixed rate of payment on the interest rate swap, the swap will reduce common share net earnings. If, on the other hand, short-term interest rates are higher than the fixed rate of payment on the interest rate swap, the swap will enhance common share net earnings. Buying interest rate caps could enhance the performance of the common shares by providing a maximum leverage expense. Buying interest rate caps could also decrease the net earnings of the common shares in the event that the premium paid by a Fund to the counterparty exceeds the additional amount the Fund would have been required to pay had it not entered into the cap agreement.

Interest rate swaps and caps do not involve the delivery of securities or other underlying assets or principal. Accordingly, the risk of loss with respect to interest rate swaps is limited to the net amount of interest payments that a Fund is contractually obligated to make. If the counterparty defaults, the Fund would not be able to use the anticipated net receipts under the swap or cap to offset interest payments. Depending on whether the Fund would be entitled to receive net payments from the counterparty on the swap or cap, which in turn would depend on the general state of short-term interest rates at that point in time, such a default could negatively impact the performance of the common shares.

Although this will not guarantee that the counterparty does not default, a Fund will not enter into an interest rate swap or cap transaction with any counterparty that the Adviser believes does not

S-8

have the financial resources to honor its obligation under the interest rate swap or cap transaction. Further, the Adviser will continually monitor the financial stability of a counterparty to an interest rate swap or cap transaction in an effort to proactively protect the Funds’ investments.

In addition, at the time the interest rate swap or cap transaction reaches its scheduled termination date, there is a risk that the Funds would not be able to obtain a replacement transaction or that the terms of the replacement would not be as favorable as on the expiring transaction. If this occurs, it could have a negative impact on the performance of a Fund’s common shares.

Segregation of Assets

As closed-end investment companies registered with the SEC, each Fund is subject to the federal securities laws, including the Investment Company Act of 1940, as amended (the “1940 Act”), the rules thereunder, and various interpretive provisions of the SEC and its staff. In accordance with these laws, rules and positions, each Fund must “set aside” (often referred to as “asset segregation”) liquid assets, or engage in other SEC or staff-approved measures, to “cover” open positions with respect to certain kinds of derivatives instruments. In the case of forward currency contracts that are not contractually required to cash settle, for example, each Fund must set aside liquid assets equal to such contracts’ full notional value while the positions are open. With respect to forward currency contracts that are contractually required to cash settle, however, a Fund is permitted to set aside liquid assets in an amount equal to such Fund’s daily marked-to-market net obligations (i.e., the Fund’s daily net liability) under the contracts, if any, rather than such contracts’ full notional value. Each Fund reserves the right to modify its asset segregation policies in the future to comply with any changes in the positions from time to time articulated by the SEC or its staff regarding asset segregation.

Each Fund generally will use its assets to cover its obligations as required by the 1940 Act, the rules thereunder, and applicable positions of the SEC and its staff. As a result of such segregation, such assets may not be used for other operational purposes.

Each Fund may invest in inverse floating rate securities issued by special purpose trusts. With respect to such investments, each Fund will segregate or earmark assets in an amount equal to at least 100% of the face amount of the floating rate securities issued by such trust.

Short-Term Investments

Short-Term Taxable Fixed Income Securities. For temporary defensive purposes or to keep cash on hand fully invested, the Funds may invest up to 100% of its net assets in cash equivalents and short-term taxable fixed-income securities, although the Funds intend to invest in taxable short-term investments only in the event that suitable tax-exempt short-term investments are not available at reasonable prices and yields. Investment in taxable short-term investments would result in a portion of the dividends paid being subject to regular federal income tax and the federal alternative minimum tax. Short-term taxable fixed income investments are defined to include, without limitation, the following:

(a) U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest that are either issued or guaranteed by the U.S. Treasury or by U.S. government agencies or instrumentalities. U.S. government agency securities include securities issued by (a) the Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, and the Government National Mortgage Association, whose securities are supported by the full faith and credit of the United States; (b) the Federal Home Loan Banks, Federal Intermediate Credit Banks, and the Tennessee

S-9

Valley Authority, whose securities are supported by the right of the agency to borrow from the U.S. Treasury; (c) the Federal National Mortgage Association, whose securities are supported by the discretionary authority of the U.S. government to purchase certain obligations of the agency or instrumentality; and (d) the Student Loan Marketing Association, whose securities are supported only by its credit. While the U.S. government provides financial support to such U.S. government-sponsored agencies or instrumentalities, no assurance can be given that it always will do so since it is not so obligated by law. The U.S. government, its agencies, and instrumentalities do not guarantee the market value of their securities. Consequently, the value of such securities may fluctuate.

(b) Certificates of deposit issued against funds deposited in a bank or a savings and loan association. Such certificates are for a definite period of time, earn a specified rate of return, and are normally negotiable. The issuer of a certificate of deposit agrees to pay the amount deposited plus interest to the bearer of the certificate on the date specified thereon. Under current FDIC regulations, the maximum insurance payable as to any one certificate of deposit is $100,000; therefore, certificates of deposit purchased by the Funds may not be fully insured.

(c) Repurchase agreements, which involve purchases of debt securities. At the time a Fund purchases securities pursuant to a repurchase agreement, it simultaneously agrees to resell and redeliver such securities to the seller, who also simultaneously agrees to buy back the securities at a fixed price and time. This assures a predetermined yield for a Fund during its holding period, since the resale price is always greater than the purchase price and reflects an agreed-upon market rate. Such actions afford an opportunity for the Funds to invest temporarily available cash. The Funds may enter into repurchase agreements only with respect to obligations of the U.S. government, its agencies or instrumentalities; certificates of deposit; or bankers’ acceptances in which the Funds may invest. Repurchase agreements may be considered loans to the seller, collateralized by the underlying securities. The risk to the Funds is limited to the ability of the seller to pay the agreed-upon sum on the repurchase date; in the event of default, the repurchase agreement provides that the Funds are entitled to sell the underlying collateral. If the value of the collateral declines after the agreement is entered into, and if the seller defaults under a repurchase agreement when the value of the underlying collateral is less than the repurchase price, the Funds could incur a loss of both principal and interest. The investment adviser monitors the value of the collateral at the time the action is entered into and at all times during the term of the repurchase agreement. The Funds’ investment adviser does so in an effort to determine that the value of the collateral always equals or exceeds the agreed-upon repurchase price to be paid to the Funds. If the seller were to be subject to a federal bankruptcy proceeding, the ability of the Funds to liquidate the collateral could be delayed or impaired because of certain provisions of the bankruptcy laws.

(d) Commercial paper, which consists of short-term unsecured promissory notes, including variable rate master demand notes issued by corporations to finance their current operations. Master demand notes are direct lending arrangements between the Funds and a corporation. There is no secondary market for such notes. However, they are redeemable by the Funds at any time. The Adviser will consider the financial condition of the corporation (e.g., earning power, cash flow, and other liquidity ratios) and will continuously monitor the corporation’s ability to meet all of its financial obligations, because a Fund’s liquidity might be impaired if the corporation were unable to pay principal and interest on demand. Investments in commercial paper will be limited to commercial paper rated in the highest categories by a

S-10

major rating agency and which mature within one year of the date of purchase or carry a variable or floating rate of interest.

Short-Term Tax-Exempt Fixed Income Securities. Short-term tax-exempt fixed-income securities are securities that are exempt from regular federal income tax and mature within three years or less from the date of issuance. Short-term tax-exempt fixed income securities are defined to include, without limitation, the following:

1. Bond Anticipation Notes (“BANs”) are usually general obligations of state and local governmental issuers which are sold to obtain interim financing for projects that will eventually be funded through the sale of long-term debt obligations or bonds. The ability of an issuer to meet its obligations on its BANs is primarily dependent on the issuer’s access to the long-term municipal bond market and the likelihood that the proceeds of such bond sales will be used to pay the principal and interest on the BANs.

2. Tax Anticipation Notes (“TANs”) are issued by state and local governments to finance the current operations of such governments. Repayment is generally to be derived from specific future tax revenues. TANs are usually general obligations of the issuer. A weakness in an issuer’s capacity to raise taxes due to, among other things, a decline in its tax base or a rise in delinquencies, could adversely affect the issuer’s ability to meet its obligations on outstanding TANs.

3. Revenue Anticipation Notes (“RANs”) are issued by governments or governmental bodies with the expectation that future revenues from a designated source will be used to repay the notes. In general, they also constitute general obligations of the issuer. A decline in the receipt of projected revenues, such as anticipated revenues from another level of government, could adversely affect an issuer’s ability to meet its obligations on outstanding RANs. In addition, the possibility that the revenues would, when received, be used to meet other obligations could affect the ability of the issuer to pay the principal and interest on RANs.

4. Construction Loan Notes are issued to provide construction financing for specific projects. Frequently, these notes are redeemed with funds obtained from the Federal Housing Administration.

5. Bank Notes are notes issued by local government bodies and agencies, such as those described above to commercial banks as evidence of borrowings. The purposes for which the notes are issued are varied but they are frequently issued to meet short-term working capital or capital project needs. These notes may have risks similar to the risks associated with TANs and RANs.

6. Tax-Exempt Commercial Paper (“Municipal Paper”) represents very short-term unsecured, negotiable promissory notes, issued by states, municipalities and their agencies. Payment of principal and interest on issues of municipal paper may be made from various sources to the extent the funds are available therefrom. Maturities of municipal paper generally will be shorter than the maturities of TANs, BANs or RANs. There is a limited secondary market for issues of Municipal Paper.

Certain municipal securities may carry variable or floating rates of interest whereby the rate of interest is not fixed but varies with changes in specified market rates or indices, such as a bank prime rate or a tax-exempt money market index.

S-11

While the various types of notes described above as a group represent the major portion of the short-term tax-exempt note market, other types of notes are available in the marketplace, and the Funds may invest in such other types of notes to the extent permitted under its investment objectives, policies and limitations. Such notes may be issued for different purposes and may be secured differently from those mentioned above.

Inverse Floating Rate Securities and Floating Rate Securities

Inverse Floating Rate Securities. Inverse floating rate securities (sometimes referred to as “inverse floaters”) are securities whose interest rates bear an inverse relationship to the interest rate on another security or the value of an index. Generally, inverse floating rate securities represent beneficial interests in a special purpose trust formed by a third party sponsor for the purpose of holding municipal bonds. The special purpose trust typically sells two classes of beneficial interests or securities: floating rate securities (sometimes referred to as short-term floaters or tender option bonds) and inverse floating rate securities (sometimes referred to as inverse floaters or residual interest securities). Both classes of beneficial interests are represented by certificates. The short-term floating rate securities have first priority on the cash flow from the municipal bonds held by the special purpose trust. Typically, a third party, such as a bank, broker-dealer or other financial institution, grants the floating rate security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees. The holder of the short-term floater effectively holds a demand obligation that bears interest at the prevailing short-term, tax-exempt rate. However, the institution granting the tender option will not be obligated to accept tendered short-term floaters in the event of certain defaults or a significant downgrade in the credit rating assigned to the bond issuer. For its inverse floating rate investment, each Fund receives the residual cash flow from the special purpose trust. Because the holder of the short-term floater is generally assured liquidity at the face value of the security, each Fund as the holder of the inverse floater assumes the interest rate cash flow risk and the market value risk associated with the municipal bond deposited into the special purpose trust. The volatility of the interest cash flow and the residual market value will vary with the degree to which the trust is leveraged. This is expressed in the ratio of the face value of the short-term floaters in relation to the inverse floaters that are issued by the special purpose trust. Each Fund expects to make limited investments in inverse floaters, with leverage ratios that may vary between one and three times. However, each Fund is permitted to invest in highly leveraged inverse floating rate securities. In addition, all voting rights and decisions to be made with respect to any other rights relating to the municipal bonds held in the special purpose trust are passed through to a Fund, as the holder of the residual inverse floating rate securities.

Because increases in either the interest rate on the securities or the value of indexes (with which inverse floaters maintain their inverse relationship) reduce the residual interest paid on inverse floaters, inverse floaters’ value is generally more volatile than that of fixed rate bonds. The market price of inverse floating rate securities is more volatile than the underlying securities due to leverage. These securities generally will underperform the market of fixed rate bonds in a rising interest rate environment but tend to outperform the market of fixed rate bonds when interest rates decline or remain relatively stable. Although volatile, inverse floaters typically offer the potential for yields exceeding the yields available on fixed rate bonds with comparable credit quality, coupon, call provisions and maturity.

Inverse floaters have varying degrees of liquidity or illiquidity based upon, among other things, the liquidity of the underlying bonds deposited in a special purpose trust. Each Fund may invest in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund. In the Adviser’s discretion, each Fund may enter into a separate shortfall and forbearance agreement with the

S-12

third party sponsor of a special purpose trust. Each Fund may enter into such recourse agreements (i) when the liquidity provider to the special purpose trust requires such an agreement because the level of leverage in the trust exceeds the level that the liquidity provider is willing to support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing the trust in the event that the municipal obligation held in the trust has declined in value. Such an agreement would require a Fund to reimburse the third party sponsor of such inverse floater, upon termination of the trust issuing the inverse floater, the difference between the liquidation value of the bonds held in the trust and the principal amount due to the holders of floating rate interests. Such agreements may expose a Fund to a risk of loss that exceeds its investment in the inverse floating rate securities. Absent a shortfall and forbearance agreement, each Fund would not be required to make such a reimbursement. If a Fund chooses not to enter into such an agreement, the special purpose trust could be liquidated, and such Fund could incur a loss. Each Fund will segregate or earmark liquid assets with its custodian in accordance with the 1940 Act to cover its obligations with respect to its investments in special purpose trusts. See also “Segregation of Assets” in the Statement of Additional Information.

Floating Rate Securities. Each Fund may also invest in floating rate securities, as described above, issued by special purpose trusts. Floating rate securities may take the form of short-term floating rate securities or the option period may be substantially longer. Generally, the interest rate earned will be based upon the market rates for municipal securities with maturities or remarketing provisions that are comparable in duration to the periodic interval of the tender option, which may vary from weekly, to monthly, to extended periods of one year or multiple years. Since the option feature has a shorter term than the final maturity or first call date of the underlying bond deposited in the trust, each Fund as the holder of the floating rate security relies upon the terms of the agreement with the financial institution furnishing the option as well as the credit strength of that institution. As further assurance of liquidity, the terms of the trust provide for a liquidation of the municipal security deposited in the trust and the application of the proceeds to pay off the floating rate security. The trusts that are organized to issue both short-term floating rate securities and inverse floaters generally include liquidation triggers to protect the investor in the floating rate security.

When-Issued and Delayed Delivery Transactions

Each Fund may buy and sell municipal securities on a when-issued or delayed delivery basis, making payment or taking delivery at a later date, normally within 15-45 days of the trade date. On such transactions, the payment obligation and the interest rate are fixed at the time the purchaser enters into the commitment. Beginning on the date a Fund enters into a commitment to purchase securities on a when-issued or delayed delivery basis, such Fund is required under the rules of the SEC to maintain in a separate account liquid assets, consisting of cash, cash equivalents or liquid securities having a market value at all times of at least equal to the amount of any delayed payment commitment. Income generated by any such assets which provide taxable income for federal income tax purposes is includable in the taxable income of such Fund and, to the extent distributed, will be taxable distributions to shareholders. Each Fund may enter into contracts to purchase securities on a forward basis (i.e., where settlement will occur more than 60 days from the date of the transaction) only to the extent that the Fund specifically collateralizes such obligations with a security that is expected to be called or mature within 60 days before or after the settlement date of the forward transaction. The commitment to purchase securities on a when-issued, delayed delivery or forward basis may involve an element of risk because no interest accrues on the bonds prior to settlement and at the time of delivery the market value may be less than their cost.

S-13

Structured Notes

The Funds may utilize structured notes and similar instruments for investment purposes and also for hedging purposes. Structured notes are privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a benchmark asset, market or interest rate (an “embedded index”), such as selected securities, an index of securities or specified interest rates, or the differential performance of two assets or markets. The terms of such structured instruments normally provide that their principal and/or interest payments are to be adjusted upwards or downwards (but not ordinarily below zero) to reflect changes in the embedded index while the structured instruments are outstanding. As a result, the interest and/or principal payments that may be made on a structured product may vary widely, depending upon a variety of factors, including the volatility of the embedded index and the effect of changes in the embedded index on principal and/or interest payments. The rate of return on structured notes may be determined by applying a multiplier to the performance or differential performance of the referenced index or indices or other assets. Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss.

Other Investment Companies

The Funds may invest up to 10% of its Managed Assets in securities of other open- or closed-end investment companies (including exchange-traded funds (often referred to as “ETFs”)) that invest primarily in municipal securities of the types in which the Funds may invest directly. As a shareholder in another investment company, the Funds will bear its ratable share of that investment company’s expenses, and would remain subject to payment of the Funds’ advisory and administrative fees with respect to assets so invested. Common shareholders would therefore be subject to duplicative expenses to the extent the Funds invest in other investment companies. The Adviser will take expenses into account when evaluating the investment merits of an investment in the investment company relative to available municipal bond investments. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to leverage risks. The net asset value and market value of leveraged shares will be more volatile and the yield to shareholders will tend to fluctuate more than the yield generated by unleveraged shares.

Other Investment Policies and Techniques

Illiquid Securities. The Fund may invest in illiquid securities (i.e., securities that are not readily marketable), including, but not limited to, restricted securities (securities the disposition of which is restricted under the federal securities laws), securities that may only be resold pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and repurchase agreements with maturities in excess of seven days.

Restricted securities may be sold only in privately negotiated transactions or in a public offering with respect to which a registration statement is in effect under the Securities Act. Where registration is required, the Funds may be obligated to pay all or part of the registration expenses and a considerable period may elapse between the time of the decision to sell and the time the Funds may be permitted to sell a security under an effective registration statement. If, during such a period, adverse market conditions were to develop, the Funds might obtain a less favorable price than that which prevailed when it decided to sell. Illiquid securities will be priced at a fair value as determined in good faith by the Board of Trustees or Board of Directors, as applicable, or its delegate.

S-14

Portfolio Trading and Turnover Rate. Portfolio trading may be undertaken to accomplish the investment objectives of the Funds in relation to actual and anticipated movements in interest rates. In addition, a security may be sold and another of comparable quality purchased at approximately the same time to take advantage of what the Adviser believes to be a temporary price disparity between the two securities. Temporary price disparities between two comparable securities may result from supply and demand imbalances where, for example, a temporary oversupply of certain bonds may cause a temporarily low price for such bonds, as compared with other bonds of like quality and characteristics. The Funds may also engage to a limited extent in short-term trading consistent with their investment objectives. Securities may be sold in anticipation of a market decline (a rise in interest rates) or purchased in anticipation of a market rise (a decline in interest rates) and later sold, but the Funds will not engage in trading solely to recognize a gain.

Subject to the foregoing, the Funds will attempt to achieve their investment objectives by prudent selection of municipal securities with a view to holding them for investment. While there can be no assurance thereof, the Funds anticipate that their annual portfolio turnover rates will generally not exceed 100%. However, the rate of turnover will not be a limiting factor when the Funds deem it desirable to sell or purchase securities. Therefore, depending upon market conditions, the annual portfolio turnover rate of the Funds may exceed 100% in particular years. High portfolio turnover may result in the realization of net short term capital gains by the Fund which, when distributed to shareholders, will be taxable as ordinary income for federal income tax purposes.

Repurchase Agreements. As temporary investments, the Funds may invest in repurchase agreements. A repurchase agreement is a contractual agreement whereby the seller of securities (U.S. government securities or municipal bonds) agrees to repurchase the same security at a specified price on a future date agreed upon by the parties. The agreed upon repurchase price determines the yield during a Fund’s holding period. Repurchase agreements are considered to be loans collateralized by the underlying security that is the subject of the repurchase contract. Income generated from transactions in repurchase agreements is taxable for federal income tax purposes and, therefore, is required to be allocated proportionately by the Funds between common shares and preferred shares. The Funds will enter into repurchase agreements with registered securities dealers or domestic banks that, in the opinion of the Adviser, present minimal credit risk. The risk to the Funds is limited to the ability of the issuer to pay the agreed upon repurchase price on the delivery dates; however, although the value of the underlying collateral at the time the transaction is entered into always equals or exceeds the agreed upon repurchase price, if the value of the collateral declines there is a risk of loss of both principal and interest. In the event of default, the collateral may be sold but the Funds might incur a loss if the value of the collateral declines, and might incur disposition costs or experience delays in connection with liquidating the collateral. In addition, if bankruptcy proceedings are commenced with respect to the seller of the security, realization upon the collateral by the Funds may be delayed or limited. The Adviser will monitor the value of the collateral at the time the transaction is entered into and at all times subsequent during the term of the repurchase agreement in an effort to determine that such value always equals or exceeds the agreed upon repurchase price. In the event the value of the collateral declines below the repurchase price, the Adviser will demand additional collateral from the issuer to increase the value of the collateral to at least that of the repurchase price, including interest.

Zero Coupon Bonds. The Funds may invest in zero coupon bonds. A zero coupon bond is a bond that does not pay interest for its entire life. The market prices of zero coupon bonds are affected to a greater extent by changes in prevailing levels of interest rates and thereby tend to be more volatile in price than securities that pay interest periodically. In addition, because the Funds accrue income with respect to these securities prior to the receipt of such interest, it may have to dispose of portfolio securities under disadvantageous circumstances in order to obtain cash needed to pay income dividends in amounts necessary to avoid unfavorable tax consequences.

S-15

INVESTMENT RESTRICTIONS

In addition to each Fund’s investment objectives, the following investment restrictions are fundamental policies for the Funds and may not be changed without the approval of the holders of a majority of the outstanding common shares and preferred shares, of such Fund, voting together, and of the holders of a majority of the outstanding preferred shares, voting separately. For this purpose, “a majority of the outstanding shares” means the vote of (1) 67% or more of the voting securities present at a meeting, if the holders of more than 50% of the outstanding voting securities are present or represented by proxy; or (2) more than 50% of the outstanding voting securities, whichever is less.

Except as described below, each Fund may not:

Accordingly, the sections and subsections of the prospectus referenced in this fundamental investment restriction have been replaced.

|  | 10) Pledge, mortgage or hypothecate its assets, except that, to secure borrowings permitted by [paragraph #3] above, it may pledge securities having a market value at the time of pledging not exceeding 20% of the value of the Fund’s total assets;
|  | 11) Invest more than 10% of its total assets in repurchase agreements maturing in more than seven days; and
|  | 12) Purchase or retain the securities of any issuer other than the securities of the Fund if to the Fund’s knowledge, those trustees of the Fund, or those officers and directors of the Adviser, who individually own beneficially more than 1/2 of 1% of the outstanding securities of such issuer, together own beneficially more than 5% of such outstanding securities.

For the purpose of applying the limitation set forth in subparagraph (9) above, an issuer shall be deemed the separate issuer when its assets and revenues are separate from other governmental entities and its securities are backed only by its assets and revenues. Similarly, in the case of a non-governmental issuer, if the security is backed only by the assets and revenues of the non-governmental issuer, then such non-governmental issuer would be deemed to be the single issuer. Where a security is also backed by the enforceable obligation of a superior or unrelated governmental or other entity (other than a bond insurer), it shall also be included in the computation of securities owned that are issued by such governmental or other entity. Where a security is guaranteed by a governmental entity or some other facility, such as a bank guarantee or letter of credit, such a guarantee or letter of credit would be considered a separate security and would be treated as an issue of such government, other entity or bank. When a municipal security is insured by bond insurance, it shall not be considered a security that is issued or guaranteed by the insurer; instead, the issuer of such municipal security will be determined in accordance with the principles set forth above. The foregoing restrictions do not limit the percentage of a Fund’s assets that may be invested in municipal securities insured by any given insurer.

Each Fund is diversified for purposes of the 1940 Act. Consequently, as to 75% of each Fund’s total assets, a Fund may not (i) purchase the securities of any one issuer (other than cash, securities of other investment companies and securities issued by the U.S. government or its agencies or instrumentalities) if immediately after such purchase, more than 5% of the value of the Fund’s total assets would be invested in securities of such issuer or (ii) purchase more than 10% of the outstanding voting securities of such issuer.

Subject to certain exemptions, under the 1940 Act, each Fund may invest up to 10% of its total assets in the aggregate in shares of other investment companies and up to 5% of its total assets in any one investment company, provided the investment does not represent more than 3% of the voting stock

S-18

of the acquired investment company at the time such shares are purchased. As a stockholder in any investment company, each Fund will bear its ratable share of that investment company’s expenses and will remain subject to payment of each Fund’s management, advisory and administrative fees with respect to assets so invested. Holders of common shares of each Fund would therefore be subject to duplicative expenses to the extent a Fund invests in other investment companies. In addition, the securities of other investment companies may be leveraged and therefore will be subject to the same leverage risks described herein.

In addition to the foregoing fundamental investment policies, each Fund is also subject to the following non-fundamental restrictions and policies, which may be changed by the Board of Trustees or Board of Directors, as applicable. Each Fund may not:

(1) Sell securities short, unless the Fund owns or has the right to obtain securities equivalent in kind and amount to the securities sold, at no added cost, and provided that transactions in options, futures contracts, options on futures contracts, or other derivative instruments are not deemed to constitute selling securities short.

(2a) (Acquiring Fund) Purchase securities of other open- or closed-end investment companies except in compliance with the 1940 Act.

(2b) (Acquired Funds) Invest more than 10% of its Managed Assets in securities of other open- or closed-end investment companies (including ETFs) that invest primarily in municipal securities of the types in which the Fund may invest directly.

(3) Enter into futures contracts or related options or forward contracts, if more than 30% of the Fund’s net assets would be represented by futures contracts or more than 5% of the Fund’s net assets would be committed to initial margin deposits and premiums on futures contracts and related options.

(4) Purchase securities when borrowings exceed 5% of its total assets if and so long as preferred shares are outstanding.

(5) Purchase securities of companies for the purpose of exercising control, except that the Fund may invest up to 5% of its net assets (including assets attributable to preferred shares, if any) in tax-exempt or taxable fixed-income securities or equity securities for the purpose of acquiring control of an issuer whose municipal bonds (a) the Fund already owns and (b) have deteriorated or are expected shortly to deteriorate significantly in credit quality, provided Nuveen Asset Management determines that such investment should enable the Fund to better maximize the value of its existing investment in such issuer.

The restrictions and other limitations set forth above will apply only at the time of purchase of securities and will not be considered violated unless an excess or deficiency occurs or exists immediately after and as a result of an acquisition of securities.

Each Fund may be subject to certain restrictions imposed by either guidelines of one or more NRSROs that may issue ratings for Preferred Shares, or, if issued, commercial paper or notes, or, if a Fund borrows from a lender, by the lender. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on a Fund by the 1940 Act. If these restrictions were to apply, it is not anticipated that these covenants or guidelines would impede

S-19

Nuveen Asset Management from managing a Fund’s portfolio in accordance with the Fund’s investment objectives and policies. A copy of the current Rating Agency Guidelines will be provided to any holder of Preferred Shares promptly upon request therefor made by such holder to the Fund by writing the Fund at 333 West Wacker Drive, Chicago, Illinois 60606.

Portfolio Turnover

Each Fund may buy and sell municipal securities to accomplish its investment objective(s) in relation to actual and anticipated changes in interest rates. Each Fund also may sell one municipal bond and buy another of comparable quality at about the same time to take advantage of what Nuveen Asset Management believes to be a temporary price disparity between the two bonds that may result from imbalanced supply and demand. Each Fund also may engage in a limited amount of short-term trading, consistent with its investment objectives. Each Fund may sell securities in anticipation of a market decline (a rise in interest rates) or buy securities in anticipation of a market rise (a decline in interest rates) and later sell them, but a Fund will not engage in trading solely to recognize a gain. Each Fund will attempt to achieve its investment objectives by prudently selecting municipal securities with a view to holding them for investment. Although a Fund cannot accurately predict its annual portfolio turnover rate, each Fund expects, though it cannot guarantee, that its annual portfolio turnover rate generally will not exceed 100% under normal circumstances.

The portfolio turnover rates of the Funds for the last two fiscal years ended October 31 for which financial statements are available were as follows:

Fund |  | 2011 |  |  | 2010 |
Acquiring Fund |  |  | 2 | % |  |  | 2 | %
Premier Opportunity |  |  | 8 | % |  |  | 12 | %
Premium Opportunity |  |  | 20 | % |  |  | 10 | %

There are no limits on the rate of portfolio turnover, and investments may be sold without regard to length of time held when investment considerations warrant such action. A higher portfolio turnover rate results in correspondingly greater brokerage commissions and other transactional expenses that are borne by each Fund. In addition, high portfolio turnover may result in the realization of net short-term capital gains by a Fund which, when distributed to shareholders, will be taxable as ordinary income for federal income tax purposes.

MANAGEMENT OF THE FUNDS

Trustees and Officers

The management of the Funds, including general supervision of the duties performed for each Fund under its investment management agreement with Nuveen Fund Advisors (“the management agreement”), is the responsibility of the Funds’ Board. (The same Board and officers oversee each Fund.) The number of Board Members is ten, one of whom is an “interested person” (as the term “interested person” is defined in the 1940 Act) and nine of whom are not interested persons (referred to herein as “independent trustees”). None of the independent Board Members has ever been a trustee, director or employee of, or consultant to, Nuveen Investments, Inc. (“Nuveen Investments”), Nuveen Fund Advisors, Nuveen Asset Management or their affiliates.

S-20

With respect to the Acquiring Fund and Premium Opportunity, the Board is divided into three classes, Class I, Class II and Class III, with the Class I Board Members serving until the 2013 annual meeting, the Class II Board Members serving until the 2014 annual meeting and the Class III Board Members serving until the 2015 annual meeting, in each case until their respective successors are elected and qualified. Currently, Judith M. Stockdale, Carole E. Stone and Virginia L. Stringer are slated in Class I, John P. Amboian, David J. Kundert and Terence J. Toth are slated in Class II and Robert P. Bremner and Jack B. Evans are slated in Class III. In addition, two Board Members are elected by holders of preferred shares annually. Currently, Messrs. William C. Hunter and William J. Schneider serve as the Board Members elected by holders of Preferred Shares for a term of one year. With respect to Premier Opportunity, Board Members serve annual terms until the next annual meeting or until their successors have been duly elected and qualified. Board Members Amboian, Bremner, Evans, Kundert, Stockdale, Stone, Stringer and Toth currently serve as the Board Members elected by holders of common shares and preferred shares, voting together as a single class, and Board Members Hunter and Schneider serve as the Board Members elected by holders of the preferred shares. The officers of the Funds serve annual terms and are elected on an annual basis. The names, business addresses and birthdates of the Board Members and officers of the Funds, their principal occupations and other affiliations during the past five years, the number of portfolios each oversees and other directorships they hold are set forth below.

BOARD LEADERSHIP STRUCTURE AND RISK OVERSIGHT

The Board of each Fund oversees the operations and management of the Fund, including the duties performed for the Funds by the Adviser. The Board has adopted a unitary board structure. A unitary board consists of one group of directors who serve on the board of every fund in the complex. In adopting a unitary board structure, the Board Members seeks to provide effective governance through establishing a board, the overall composition of which will, as a body, possess the appropriate skills, independence and experience to oversee the Funds’ business. With this overall framework in mind, when the Board, through its Nominating and Governance Committee discussed below, seeks nominees for the Board, the Board Members consider not only the candidate’s particular background, skills and experience, among other things, but also whether such background, skills and experience enhance the Board’s diversity and at the same time complement the Board given its current composition and the mix of skills and experiences of the incumbent Board Members. The Nominating and Governance Committee believes that the Board generally benefits from diversity of background, experience and views among its members, and considers this a factor in evaluating the composition of the Board, but has not adopted any specific policy on diversity or any particular definition of diversity.

The Board believes the unitary board structure enhances good and effective governance, particularly given the nature of the structure of the investment company complex. Funds in the same complex generally are served by the same service providers and personnel and are governed by the same regulatory scheme which raises common issues that must be addressed by the Board Members across the fund complex (such as compliance, valuation, liquidity, brokerage, trade allocation or risk management). The Board believes it is more efficient to have a single board review and oversee common policies and procedures which increases the Board’s knowledge and expertise with respect to the many aspects of fund operations that are complex-wide in nature. The unitary structure also enhances the Board’s influence and oversight over the Adviser and other service providers.

S-32

In an effort to enhance the independence of the Board, the Board also has a Chairman that is an Independent Board Member. The Board recognizes that a chairman can perform an important role in setting the agenda for the Board, establishing the boardroom culture, establishing a point person on behalf of the Board for Fund management, and reinforcing the Board’s focus on the long-term interests of shareholders. The Board recognizes that a chairman may be able to better perform these functions without any conflicts of interests arising from a position with Fund management. Accordingly, the Board Members have elected Robert P. Bremner as the independent Chairman of the Board. Specific responsibilities of the Chairman include: (i) presiding at all meetings of the Board and of the shareholders; (ii) seeing that all orders and resolutions of the Board Members are carried into effect; and (iii) maintaining records of and, whenever necessary, certifying all proceedings of the Board and the shareholders.

Although the Board has direct responsibility over various matters (such as advisory contracts, underwriting contracts and Fund performance), the Board also exercises certain of its oversight responsibilities through several committees that it has established and which report back to the full Board. The Board believes that a committee structure is an effective means to permit Board Members to focus on particular operations or issues affecting the Funds, including risk oversight. More specifically, with respect to risk oversight, the Board has delegated matters relating to valuation and compliance to certain committees (as summarized below) as well as certain aspects of investment risk. In addition, the Board believes that the periodic rotation of Board Members among the different committees allows the Board Members to gain additional and different perspectives on a Fund’s operations. During 2011, the Board had five standing committees: the Executive Committee, the Dividend Committee, the Audit Committee, the Compliance, Risk Management and Regulatory Oversight Committee and the Nominating and Governance Committee. The Board may also from time to time create ad hoc committees to focus on particular issues as the need arises. The membership and functions of the standing committees are summarized below.

The Executive Committee, which meets between regular meetings of the Board, is authorized to exercise all of the powers of the Board. The members of the Executive Committee are Robert P. Bremner, Chair, Judith M. Stockdale and John P. Amboian. During the fiscal year ended October 31, 2011, the Executive Committee met one time.

The Dividend Committee is authorized to declare distributions on each Fund’s shares including, but not limited to, regular and special dividends, capital gains and ordinary income distributions. The members of the Dividend Committee are Jack B. Evans, Chair, Judith M. Stockdale and Terence J. Toth. During the fiscal year ended October 31, 2011, the Dividend Committee met four times.

The Board has an Audit Committee, in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the “1934 Act”), that is composed of Independent Board Members who are also “independent” as that term is defined in the listing standards pertaining to closed-end funds of the New York Stock Exchange or NYSE Amex, as applicable. The Audit Committee assists the Board in the oversight and monitoring of the accounting and reporting policies, processes and practices of the Funds, and the audits of the financial statements of the Funds; the quality and integrity of the financial statements of the Funds; the Funds’ compliance with legal and regulatory requirements relating to the Funds’ financial statements; the independent auditors’ qualifications, performance and independence; and the pricing procedures of the Funds and the internal valuation group of Nuveen. It is the responsibility of the Audit Committee to select, evaluate and replace any independent auditors (subject only to Board and, if applicable, shareholder ratification) and to determine their compensation.

S-33

The Audit Committee is also responsible for, among other things, overseeing the valuation of securities comprising the Funds’ portfolios. Subject to the Board’s general supervision of such actions, the Audit Committee addresses any valuation issues, oversees the Funds’ pricing procedures and actions taken by Nuveen’s internal valuation group which provides regular reports to the committee, reviews any issues relating to the valuation of the Funds’ securities brought to its attention and considers the risks to the Funds in assessing the possible resolutions to these matters. The Audit Committee may also consider any financial risk exposures for the Funds in conjunction with performing its functions.

To fulfill its oversight duties, the Audit Committee receives annual and semi-annual reports and has regular meetings with the external auditors for the Funds and the internal audit group at Nuveen. The Audit Committee also may review in a general manner the processes the Board or other Board committees have in place with respect to risk assessment and risk management as well as compliance with legal and regulatory matters relating to the Funds’ financial statements. The Audit Committee operates under a written Audit Committee Charter adopted and approved by the Board, which Charter conforms to the listing standards of the New York Stock Exchange or NYSE Amex, as applicable. Members of the Audit Committee are independent (as set forth in the Charter) and free of any relationship that, in the opinion of the Board Members, would interfere with their exercise of independent judgment as an Audit Committee member. The members of the Audit Committee are Robert P. Bremner, David J. Kundert, Chair, William J. Schneider, Carole E. Stone and Terence J. Toth, each of whom is an Independent Trustee of the Funds. During the fiscal year ended October 31, 2011, the Audit Committee met four times.

The Compliance, Risk Management and Regulatory Oversight Committee (the “Compliance Committee”) is responsible for the oversight of compliance issues, risk management and other regulatory matters affecting the Funds that are not otherwise within the jurisdiction of the other committees. The Board has adopted and periodically reviews policies and procedures designed to address the Funds’ compliance and risk matters. As part of its duties, the Compliance Committee reviews the policies and procedures relating to compliance matters and recommends modifications thereto as necessary or appropriate to the full Board; develops new policies and procedures as new regulatory matters affecting the Funds arise from time to time; evaluates or considers any comments or reports from examinations from regulatory authorities and responses thereto; and performs any special reviews, investigations or other oversight responsibilities relating to risk management, compliance and/or regulatory matters as requested by the Board.

In addition, the Compliance Committee is responsible for risk oversight, including, but not limited to, the oversight of risks related to investments and operations. Such risks include, among other things, exposures to particular issuers, market sectors, or types of securities; risks related to product structure elements, such as leverage; and techniques that may be used to address those risks, such as hedging and swaps. In assessing issues brought to the Compliance Committee’s attention or in reviewing a particular policy, procedure, investment technique or strategy, the Compliance Committee evaluates the risks to the Funds in adopting a particular approach or resolution compared to the anticipated benefits to the Funds and their shareholders. In fulfilling its obligations, the Compliance Committee meets on a quarterly basis, and at least once a year in person. The Compliance Committee receives written and oral reports from the Funds’ Chief Compliance Officer (“CCO”) and meets privately with the CCO at each of its quarterly meetings. The CCO also provides an annual report to the full Board regarding the operations of the Funds’ and other service providers’ compliance programs as well as any recommendations for modifications thereto. The Compliance Committee also receives reports from the investment services group of Nuveen regarding various investment risks. Notwithstanding the foregoing, the full Board also participates in

S-34

discussions with management regarding certain matters relating to investment risk, such as the use of leverage and hedging. The investment services group therefore also reports to the full Board at its quarterly meetings regarding, among other things, Fund performance and the various drivers of such performance. Accordingly, the Board directly and/or in conjunction with the Compliance Committee oversees matters relating to investment risks. Matters not addressed at the committee level are addressed directly by the full Board. The Compliance Committee operates under a written charter adopted and approved by the Board. The members of the Compliance Committee are Jack B. Evans, William C. Hunter, William J. Schneider, Judith M. Stockdale, Chair, and Virginia L. Stringer. During the fiscal year ended October 31, 2011, the Compliance Committee met five times.

The Nominating and Governance Committee is responsible for seeking, identifying and recommending to the Board qualified candidates for election or appointment to the Board. In addition, the Nominating and Governance Committee oversees matters of corporate governance, including the evaluation of Board performance and processes, the assignment and rotation of committee members, and the establishment of corporate governance guidelines and procedures, to the extent necessary or desirable, and matters related thereto. Although the unitary and committee structure has been developed over the years and the Nominating and Governance Committee believes the structure has provided efficient and effective governance, the committee recognizes that as demands on the Board evolve over time (such as through an increase in the number of Funds overseen or an increase in the complexity of the issues raised), the committee must continue to evaluate the Board and committee structures and their processes and modify the foregoing as may be necessary or appropriate to continue to provide effective governance. Accordingly, the Nominating and Governance Committee has a separate meeting each year to, among other things, review the Board and committee structures, their performance and functions, and recommend any modifications thereto or alternative structures or processes that would enhance the Board’s governance over the Funds’ business.

In addition, the Nominating and Governance Committee, among other things, makes recommendations concerning the continuing education of Board Members; monitors performance of legal counsel and other service providers; establishes and monitors a process by which security holders are able to communicate in writing with Board Members; and periodically reviews and makes recommendations about any appropriate changes to Board Member compensation. In the event of a vacancy on the Board, the Nominating and Governance Committee receives suggestions from various sources, including shareholders, as to suitable candidates. Suggestions should be sent in writing to Lorna Ferguson, Manager of Fund Board Relations, Nuveen Investments, 333 West Wacker Drive, Chicago, IL 60606. The Nominating and Governance Committee sets appropriate standards and requirements for nominations for new Board Members, and each nominee is evaluated under the same standards. However, the Nominating and Governance Committee reserves the right to interview any and all candidates and to make the final selection of any new Board Members. In considering a candidate’s qualifications, each candidate must meet certain basic requirements, including relevant skills and experience, time availability (including the time requirements for due diligence site visits to internal and external sub-advisers and service providers) and, if qualifying as an Independent Board Member candidate, independence from the Adviser, sub-advisers, underwriters or other service providers, including any affiliates of these entities. These skill and experience requirements may vary depending on the current composition of the Board, since the goal is to ensure an appropriate range of skills, diversity and experience, in the aggregate. Accordingly, the particular factors considered and weight given to these factors will depend on the composition of the Board and the skills and backgrounds of the incumbent Board Member at the time of consideration of the nominees. All candidates, however, must meet high expectations of personal integrity, independence, governance

S-35

experience and professional competence. All candidates must be willing to be critical within the Board and with management and yet maintain a collegial and collaborative manner toward other Board Members. The Nominating and Governance Committee operates under a written charter adopted and approved by the Board, a copy of which is available on the Funds’ website at www.nuveen.com/CEF/Info/Shareholder/FundGovernance.aspx, and is composed entirely of Independent Board Members who are also “independent” as defined by NYSE or NYSE MKT listing standards, as applicable. Accordingly, the members of the Nominating and Governance Committee are Robert P. Bremner, Chair, Jack B. Evans, William C. Hunter, David J. Kundert, William J. Schneider, Judith M. Stockdale, Carole E. Stone, Virginia L. Stringer and Terence J. Toth. During the fiscal year ended October 31, 2011, the Nominating and Governance Committee met six times.

Effective January 1, 2012, the Board approved the creation of the Closed-End Funds Committee. The Closed-End Funds Committee is responsible for assisting the Board in the oversight and monitoring of the Nuveen funds that are registered as closed-end investment companies (“Closed-End Funds”). The committee may review and evaluate matters related to the formation and the initial presentation to the Board of any new Closed-End Fund and may review and evaluate any matters relating to any existing Closed-End Fund. The committee operates under a written charter adopted and approved by the Board. The members of the Closed-End Funds Committee are Robert P. Bremner, Jack B. Evans, William C. Hunter, William J. Schneider, Chair, and Carole E. Stone.

Board Diversification and Trustee Qualifications

In determining that a particular Board Member was qualified to serve on the Board, the Board has considered each Board Member’s background, skills, experience and other attributes in light of the composition of the Board with no particular factor controlling. The Board believes that Board Members need to have the ability to critically review, evaluate, question and discuss information provided to them, and to interact effectively with Fund management, service providers and counsel, in order to exercise effective business judgment in the performance of their duties, and the Board believes each Board Member satisfies this standard. An effective Board Member may achieve this ability through his or her educational background; business, professional training or practice; public service or academic positions; experience from service as a trustee or executive of investment funds, public companies or significant private or not-for-profit entities or other organizations; and or/other life experiences. Accordingly, set forth below is a summary of the experiences, qualifications, attributes and skills that led to the conclusion, as of the date of this document, that each Board Member should continue to serve in that capacity. References to the experiences, qualifications, attributes and skills of Board Members are pursuant to requirements of the SEC, do not constitute holding out the Board or any Board Member as having any special expertise or experience and shall not impose any greater responsibility or liability on any such person or on the Board by reason thereof.

For each of the Acquiring Fund and Premium Opportunity, Class I trustees serve until the 2013 annual meeting of shareholders; Class II trustees serve until the 2014 annual meeting of shareholders; and Class III trustees will serve until the 2015 annual meeting of shareholders. As each trustee’s term expires, common shareholders are asked to elect trustees unless any Preferred Shares are outstanding at that time, in which event holders of Preferred Shares (including holders of VRDP Shares, VMTP Shares or MTP Shares), voting as a separate class, elect two trustees and the remaining trustees are elected by holders of the Fund’s common stock and holders of Preferred Shares, voting together as a single class. Holders of Preferred Shares will be entitled to elect a majority of the Fund’s trustees under certain circumstances. Trustees are elected for a term expiring at the time of the third succeeding annual meeting subsequent to their election or thereafter in each case when their respective successors are duly elected and qualified. These provisions could delay for up to two years the replacement of a majority of the Board of Trustees.

The annual retainer, fees and expenses are allocated among the Nuveen funds on the basis of relative net assets, although management may, in its discretion, establish a minimum amount to be allocated to each Fund.

S-43

The Funds do not have retirement or pension plans. Certain Nuveen funds (the “Participating Funds”) participate in a deferred compensation plan (the “Deferred Compensation Plan”) that permits an Independent Board Member to elect to defer receipt of all or a portion of his or her compensation as an Independent Board Member. The deferred compensation of a participating Independent Board Member is credited to a book reserve account of the Participating Fund when the compensation would otherwise have been paid to the Board Member. The value of the Board Member’s deferral account at any time is equal to the value that the account would have had if contributions to the account had been invested and reinvested in shares of one or more of the eligible Nuveen funds. At the time for commencing distributions from a Board Member’s deferral account, the Independent Board Member may elect to receive distributions in a lump sum or over a period of five years. The Participating Fund will not be liable for any other fund’s obligations to make distributions under the Deferred Compensation Plan.

The Funds have no employees. The officers of the Funds and the Board Member of each Fund who is not an Independent Board Member serve without any compensation from the Funds.

The table below shows, for each Independent Board Member, the aggregate compensation paid by each Fund to each Board Member for the fiscal year ended October 31, 2011:

Type of Account Managed |  | Number of Accounts |  |  | Assets* |
Registered Investment Company |  |  | 7 |  |  | $ | 3.6 billion |
Other Pooled Investment Vehicles |  |  | 0 |  |  | $ | 0 |
Other Accounts |  |  | 4 |  |  | $ | 32.7 million |

* | None of the assets in these accounts is subject to an advisory fee based on performance.

Compensation

Portfolio manager compensation consists primarily of base pay, an annual cash bonus and long-term incentive payments.

Base pay. Base pay is determined based upon an analysis of the portfolio manager’s general performance, experience, and market levels of base pay for such position.

Annual cash bonus. The Funds’ portfolio managers are eligible for an annual cash bonus based on investment performance, qualitative evaluation and financial performance of Nuveen Asset Management.

A portion of each portfolio manager’s annual cash bonus is based on the Fund’s investment performance, generally measured over the past one- and three- or five-year periods unless the portfolio manager’s tenure is shorter. Investment performance for the Fund generally is determined by evaluating the Fund’s performance relative to its benchmark(s) and/or Lipper industry peer group.

A portion of the cash bonus is based on a qualitative evaluation made by each portfolio manager’s supervisor taking into consideration a number of factors, including the portfolio manager’s

S-46

team collaboration, expense management, support of personnel responsible for asset growth, and his or her compliance with Nuveen Asset Management’s policies and procedures.

The final factor influencing a portfolio manager’s cash bonus is the financial performance of Nuveen Asset Management based on its operating earnings.

Long-term Incentive Compensation. Certain key employees of Nuveen Investments and its affiliates, including certain portfolio managers, have received equity interests in the parent company of Nuveen Investments. In addition, certain key employees of Nuveen Asset Management, including certain portfolio managers, have received profits interests in Nuveen Asset Management which entitle their holders to participate in the firm’s growth over time.

Conflicts of Interest. Actual or apparent conflicts of interest may arise when a portfolio manager has day-today management responsibilities with respect to more than one account. More specifically, portfolio managers who manage multiple accounts are presented a number of potential conflicts, including, among others, those discussed below.

The management of multiple accounts may result in a portfolio manager devoting unequal time and attention to the management of each account. Nuveen Asset Management seeks to manage such competing interests for the time and attention of portfolio managers by having portfolio managers focus on a particular investment discipline. Most accounts managed by a portfolio manager in a particular investment strategy are managed using the same investment models.

If a portfolio manager identifies a limited investment opportunity which may be suitable for more than one account, an account may not be able to take full advantage of that opportunity due to an allocation of filled purchase or sale orders across all eligible accounts. To deal with these situations, Nuveen Asset Management has adopted procedures for allocating limited opportunities across multiple accounts.

With respect to many of its clients’ accounts, Nuveen Asset Management determines which broker to use to execute transaction orders, consistent with its duty to seek best execution of the transaction. However, with respect to certain other accounts, Nuveen Asset Management may be limited by the client with respect to the selection of brokers or may be instructed to direct trades through a particular broker. In these cases, Nuveen Asset Management may place separate, non-simultaneous, transactions for a Fund and other accounts which may temporarily affect the market price of the security or the execution of the transaction, or both, to the detriment of the Fund or the other accounts.

Some clients are subject to different regulations. As a consequence of this difference in regulatory requirements, some clients may not be permitted to engage in all the investment techniques or transactions or to engage in these transactions to the same extent as the other accounts managed by the portfolio manager. Finally, the appearance of a conflict of interest may arise where Nuveen Asset Management has an incentive, such as a performance-based management fee, which relates to the management of some accounts, with respect to which a portfolio manager has day-to-day management responsibilities.

Nuveen Asset Management has adopted certain compliance procedures which are designed to address these types of conflicts common among investment managers. However, there is no guarantee that such procedures will detect each and every situation in which a conflict arises.

S-47

Beneficial Ownership of Securities. As of the date of this Statement of Additional Information, Mr. Brennan does not beneficially own any securities issued by the Acquiring Fund or Premier Opportunity, and Mr. White does not beneficially own any securities issued by Premium Opportunity.

Unless earlier terminated as described below, each Fund’s management agreement with Nuveen Fund Advisors will remain in effect until August 1, 2013. Each Fund’s management agreement continues in effect from year to year so long as such continuation is approved at least annually by (1) the Board or the vote of a majority of the outstanding voting securities of each Fund and (2) a majority of the trustees who are not interested persons of any party to the management agreement, cast in person at a meeting called for the purpose of voting on such approval. The management agreements may be terminated at any time, without penalty, by either the Funds or Nuveen Asset Management upon 60 days’ written notice, and they are automatically terminated in the event of their assignment as defined in the 1940 Act.

The Funds, Nuveen Fund Advisors, Nuveen Asset Management, Nuveen Investments and other related entities have adopted codes of ethics under Rule 17j-1 under the 1940 Act, that essentially prohibit certain of their personnel, including the Funds’ portfolio managers, from engaging in personal investments that compete or interfere with, or attempt to take advantage of a client’s, including the Funds’, anticipated or actual portfolio transactions, and are designed to assure that the interests of clients, including Fund shareholders, are placed before the interests of personnel in connection with personal investment transactions. The codes of ethics of the Funds, Nuveen Fund Advisors, Nuveen Asset Management and Nuveen Investments can be viewed online or downloaded from the EDGAR Database on the SEC’s internet web site at www.sec.gov. You may also review and copy those documents by visiting the SEC’s Public Reference Room in Washington, D.C. Information on the operation of the Public Reference Room may be obtained by calling the SEC at 202-942-8090. In addition, copies of those codes of ethics may be obtained, after mailing the appropriate duplicating fee, by writing to the SEC’s Public Reference Section, 100 F Street, N.E., Washington, D.C. 20549 or by e-mail request at publicinfo@sec.gov.

Each Fund invests its assets generally in municipal securities. On rare occasions the Funds may acquire, directly or through a special-purpose vehicle, equity securities of certain issuers whose securities the Funds already own when such securities have deteriorated or are expected shortly to deteriorate significantly in credit quality. The purpose of acquiring equity securities generally will be to acquire control of the issuer and to seek to prevent the credit deterioration or facilitate the liquidation or other workout of the distressed issuer’s credit problem. In the course of exercising control of a distressed issuer, Nuveen Asset Management may pursue the Funds’ interests in a variety of ways, which may entail negotiating and executing consents, agreements and other arrangements, and otherwise influencing the management of the issuer. Nuveen Asset Management does not consider such activities proxy voting for purposes of Rule 206(4)-6 under the Investment Advisers Act of 1940, as amended (the “Advisers Act”), but nevertheless provides reports to the Fund’s Board on its control activities on a quarterly basis.

In the rare event that an issuer were to issue a proxy or that the Funds were to receive a proxy issued by a cash management security, Nuveen Asset Management would either engage an independent third party to determine how the proxy should be voted or vote the proxy with the consent, or based on the instructions, of the Funds’ Board or its representative. A member of Nuveen Asset Management’s legal department would oversee the administration of the voting and ensure that records

S-48

maintained in accordance with Rule 206(4)-6 of the Advisers Act were filed with the SEC on Form N-PX, provided to the Funds’ Board and made available to shareholders as required by applicable rules.

In the event of a conflict of interest that might arise when voting proxies for the Funds, Nuveen Asset Management will defer to the recommendation of an independent third party engaged to determine how the proxy should be voted, or, alternatively, members of Nuveen Asset Management’s legal and compliance departments, in consultation with the Board, will examine the conflict of interest and seek to resolve such conflict in the best interest of each Fund. If a member of Nuveen Asset Management’s legal or compliance department or the Board has a personal conflict of interest, that member will refrain from participating in the consultation.

Information regarding how each Fund voted proxies relating to portfolio securities during the most recent twelve-month period ended June 30 will be available without charge by calling (800) 257-8787 or by accessing the SEC’s website at http://www.sec.gov.

PORTFOLIO TRANSACTIONS AND BROKERAGE

Subject to the supervision of the Board, Nuveen Asset Management is responsible for decisions to purchase and sell securities for the Funds, the negotiation of the prices to be paid and the allocation of transactions among various dealer firms. Transactions on stock exchanges involve the payment by the Funds of brokerage commissions. There generally is no stated commission in the case of securities traded in the OTC market, but the prices paid by the Funds usually include an undisclosed dealer commission or mark-up. Transactions in the OTC market can also be placed with broker-dealers who act as agents and charge brokerage commissions for effecting OTC transactions. Each Fund may place its OTC transactions either directly with principal market makers, or with broker-dealers if that is consistent with Nuveen Asset Management’s obligation to obtain best qualitative execution. In certain instances, the Funds may make purchases of underwritten issues at prices that include underwriting fees.

Portfolio securities may be purchased directly from an underwriter or in the OTC market from the principal dealers in such securities, unless it appears that a better price or execution may be obtained through other means. Portfolio securities will not be purchased from Nuveen Investments or its affiliates or affiliates of Nuveen Asset Management except in compliance with the 1940 Act.

It is Nuveen Asset Management’s policy to seek the best execution under the circumstances of each trade. Nuveen Asset Management will evaluate price as the primary consideration, with the financial condition, reputation and responsiveness of the dealer considered secondary in determining best execution. Given the best execution obtainable, it will be Nuveen Asset Management’s practice to select dealers that, in addition, furnish research information (primarily credit analyses of issuers and general economic reports) and statistical and other services to Nuveen Asset Management. It is not possible to place a dollar value on information and statistical and other services received from dealers. Since it is only supplementary to Nuveen Asset Management’s own research efforts, the receipt of research information is not expected to reduce significantly Nuveen Asset Management’s expenses. While Nuveen Asset Management will be primarily responsible for the placement of the business of the Funds, Nuveen Asset Management’s policies and practices in this regard must be consistent with the foregoing and will, at all times, be subject to review by the Board of the Funds.

S-49

Nuveen Asset Management may manage other investment accounts and investment companies for other clients that may invest in the same types of securities as the Funds and that may have investment objectives similar to those of the Funds. Nuveen Asset Management seeks to allocate portfolio transactions equitably whenever concurrent decisions are made to purchase or sell assets or securities by each Fund and another advisory account. If an aggregated order cannot be filled completely, allocations will generally be made on a pro rata basis. An order may not be allocated on a pro rata basis where, for example (i) consideration is given to portfolio managers who have been instrumental in developing or negotiating a particular investment; (ii) consideration is given to an account with specialized investment policies that coincide with the particulars of a specific investment; (iii) pro rata allocation would result in odd-lot or de minimis amounts being allocated to a portfolio or other client; or (iv) where Nuveen Asset Management reasonably determines that departure from a pro rata allocation is advisable. There may also be instances where a Fund will not participate at all in a transaction that is allocated among other accounts. While these allocation procedures could have a detrimental effect on the price or amount of the securities available to the Fund from time to time, it is the opinion of the Board that the benefits available from Nuveen Asset Management’s management outweigh any disadvantage that may arise from Nuveen Asset Management’s larger management activities and its need to allocate securities.

The following table sets forth the aggregate amount of brokerage commissions paid by the Funds for the last three fiscal years for which financial statements are available:

Fiscal Years Ended October 31

|  | 2011 |  |  | 2010 |  |  | 2009 |
Acquiring Fund |  | $ | — |  |  | $ | — |  |  | $ | — |
Premier Opportunity |  | $ | — |  |  | $ | — |  |  | $ | — |
Premium Opportunity |  | $ | — |  |  | $ | — |  |  | $ | — |

Substantially all of the Funds’ trades are effected on a principal basis.

REPURCHASE OF FUND SHARES; CONVERSION TO OPEN-END FUND

The Acquiring Fund is a closed-end investment company, and as such its shareholders will not have the right to cause the Fund to redeem their shares. Instead, the Fund’s common shares will trade in the open market at a price that will be a function of several factors, including dividend levels (which are in turn affected by expenses), net asset value, dividend stability, relative demand for and supply of such shares in the market, general market and economic conditions and other factors. Because shares of a closed-end investment company may frequently trade at prices lower than net asset value, the Acquiring Fund’s Board of Trustees has currently determined that, at least annually, it will consider action that might be taken to reduce or eliminate any material discount from net asset value in respect of common shares, which may include the repurchase of such shares in the open market or in private transactions, the making of a tender offer for such shares at net asset value, or the conversion of the Fund to an open-end investment company. There can be no assurance, however, that the Board of Trustees will decide to take any of these actions, or that share repurchases or tender offers, if undertaken, will reduce market discount.

Subject to its investment limitations, the Acquiring Fund may borrow to finance the repurchase of shares or to make a tender offer. Interest on any borrowings to finance share repurchase transactions

S-50

or the accumulation of cash by the Fund in anticipation of share repurchases or tenders will reduce the Fund’s net income. Any share repurchase, tender offer or borrowing that might be approved by the Board of Trustees would have to comply with the Securities Exchange Act of 1934, as amended, and the 1940 Act and the rules and regulations thereunder.

Although the decision to take action in response to a discount from net asset value will be made by the Board of Trustees at the time it considers such issue, it is the Board’s present policy, which may be changed by the Board, not to authorize repurchases of common shares or a tender offer for such shares if (1) such transactions, if consummated, would (a) result in the delisting of the common shares and MTP Shares from the NYSE, the NYSE MKT or elsewhere, or (b) impair the Fund’s status as a regulated investment company under the Code (which would make the Fund a taxable entity, causing the Fund’s income to be taxed at the corporate level in addition to the taxation of shareholders who receive dividends from the Fund) or as a registered closed-end investment company under the 1940 Act; (2) the Fund would not be able to liquidate portfolio securities in an orderly manner and consistent with the Fund’s investment objectives and policies in order to repurchase shares; or (3) there is, in the Board’s judgment, any (a) material legal action or proceeding instituted or threatened challenging such transactions or otherwise materially adversely affecting the Fund, (b) general suspension of or limitation on prices for trading securities on the NYSE, the NYSE MKT or elsewhere, (c) declaration of a banking moratorium by Federal or state authorities or any suspension of payment by United States or state banks in which the Fund invests, (d) material limitation affecting the Fund or the issuers of its portfolio securities by Federal or state authorities on the extension of credit by lending institutions or on the exchange of non-U.S. currency, (e) commencement of war, armed hostilities or other international or national calamity directly or indirectly involving the United States, or (f) other event or condition that would have a material adverse effect (including any adverse tax effect) on the Acquiring Fund or its shareholders if shares were repurchased. The Board of Trustees of the Fund may in the future modify these conditions in light of experience.

The repurchase by the Acquiring Fund of its shares at prices below net asset value will result in an increase in the net asset value of those shares that remain outstanding. However, there can be no assurance that share repurchases or tenders at or below net asset value will result in the Fund’s shares trading at a price equal to their net asset value. Nevertheless, the fact that the Fund’s shares may be the subject of repurchase or tender offers at net asset value from time to time, or that the Fund may be converted to an open-end investment company, may reduce any spread between market price and net asset value that might otherwise exist.

In addition, a purchase by the Acquiring Fund of its common shares will decrease the Fund’s total assets, which would likely have the effect of increasing the Fund’s expense ratio.

Conversion to an open-end company would require the approval of the holders of at least two-thirds of the Acquiring Fund’s common and preferred shares, voting as a single class, and, if conversion would adversely affect the holders of the preferred shares, approval of the holders of at least two-thirds of the Fund’s preferred shares, voting together as a single class, unless the conversion has been approved by the requisite vote of the trustees, in which case a majority vote of the requisite holders would be required. See the Joint Proxy Statement/Prospectus under “Certain Provisions in the Acquiring Fund’s Declaration of Trust and By-Laws” for a discussion of voting requirements applicable to conversion of the Fund to an open-end investment company. If the Fund converted to an open-end investment company, the Fund’s common shares would no longer be listed on the NYSE, the NYSE MKT or elsewhere, and the Fund’s Preferred Shares would no longer be outstanding. In contrast

S-51

to a closed-end investment company, shareholders of an open-end investment company may require the company to redeem their shares on any business day (except in certain circumstances as authorized by or under the 1940 Act or rules thereunder) at their net asset value, less such redemption charge, if any, as might be in effect at the time of redemption. In order to avoid maintaining large cash positions or liquidating favorable investments to meet redemptions, open-end investment companies typically engage in a continuous offering of their shares. Open-end investment companies are thus subject to periodic asset in-flows and out-flows that can complicate portfolio management. The Board of Trustees of the Fund may at any time propose conversion of the Fund to an open-end investment company depending upon its judgment as to the advisability of such action in light of circumstances then prevailing.

Before deciding whether to take any action if the Acquiring Fund’s common shares trade below net asset value, the Board of Trustees would consider all relevant factors, including the extent and duration of the discount, the liquidity of the Fund’s portfolio, the impact of any action that might be taken on the Fund or its shareholders, and market considerations. Based on these considerations, even if the Fund’s shares should trade at a discount, the Board of Trustees may determine that, in the interest of the Fund and its shareholders, no action should be taken.

FEDERAL INCOME TAX MATTERS

The following is a general summary of certain U.S. federal income tax consequences that may be relevant to a shareholder that acquires, holds and/or disposes of shares of the Acquiring Fund. This discussion only addresses U.S. federal income tax consequences to U.S. shareholders who hold their shares as capital assets and does not address all of the U.S. federal income tax consequences that may be relevant to particular shareholders in light of their individual circumstances. This discussion also does not address the tax consequences to shareholders who are subject to special rules, including, without limitation, shareholders with large positions in the Acquiring Fund, financial institutions, insurance companies, dealers in securities or foreign currencies, foreign holders, persons who hold their shares as or in a hedge against currency risk, a constructive sale, or conversion transaction, holders who are subject to the alternative minimum tax (except as discussed below), or tax-exempt or tax-deferred plans, accounts, or entities. In addition, the discussion does not address any state, local, or foreign tax consequences. The discussion reflects applicable tax laws of the United States as of the date of this Statement of Additional Information, which tax laws may be changed or subject to new interpretations by the courts or the Internal Revenue Service (“IRS”) retroactively or prospectively. No attempt is made to present a detailed explanation of all U.S. federal income tax concerns affecting the Acquiring Fund and its shareholders, and the discussion set forth herein does not constitute tax advice. INVESTORS ARE URGED TO CONSULT THEIR OWN TAX ADVISERS TO DETERMINE THE SPECIFIC TAX CONSEQUENCES TO THEM OF INVESTING IN THE ACQUIRING FUND, INCLUDING THE APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM AND THE EFFECT OF POSSIBLE CHANGES IN TAX LAWS.

The Acquiring Fund has elected to be treated, and intends to continue to qualify each year, as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended, (the “Code”), and to satisfy conditions which enable its dividends that are attributable to interest on municipal securities to be exempt from federal income tax in the hands of owners of such stock, subject to the possible application of the federal alternative minimum tax.

To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Acquiring Fund must, among other things, (a) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock, securities or non-U.S. currencies, other income derived with respect to its business of investing in such stock, securities or currencies, and net income derived from interests in “qualified publicly traded partnerships,” as defined in the Code; (b) diversify its holdings so that, at the end of each quarter of each taxable year, (i) at least 50% of the value of the Acquiring Fund’s assets is represented by cash and cash items (including receivables), U.S. Government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer limited for the purposes of this calculation to an amount not greater than 5% of the value of the Acquiring Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested in the securities (other than U.S. Government securities or the securities of other regulated investment companies) of a single issuer, or two or more issuers that the Acquiring Fund controls and are engaged in the same, similar or related trades or businesses, or the securities of one or more qualified publicly traded partnerships; and (c) distribute each year an amount equal to or greater than the sum of 90% of its investment company taxable income (as that term is defined in the Code, but without regard to the deduction for dividends paid) and 90% of its net tax-exempt interest.

If the Acquiring Fund failed to qualify as a regulated investment company in any taxable year, the Acquiring Fund would be taxed in the same manner as a regular corporation on its taxable income (even if such income were distributed to its shareholders) and distributions to shareholders would not be deductible by the Acquiring Fund in computing its taxable income. Additionally, all distributions out of earnings and profits (including distributions from net capital gain and net tax-exempt interest) would be taxed to shareholders as ordinary dividend income. Such distributions generally would be eligible (i) to be treated as “qualified dividend income,” as discussed below in the case of noncorporate shareholders and (ii) for the dividends received deduction under Section 243 of the Code (the “Dividends Received Deduction”) in the case of corporate shareholders.

The Acquiring Fund intends to continue to qualify to pay “exempt-interest” dividends, as defined in the Code, by satisfying the requirement that, at the close of each quarter of its taxable year, at least 50% of the value of its total assets consist of tax-exempt state and local bonds. Exempt-interest dividends are dividends or any part thereof (other than a capital gain dividend) paid by the Acquiring Fund which are attributable to interest on state and local bonds that pay interest exempt from regular federal income tax and are so designated by the Acquiring Fund. Exempt-interest dividends will be exempt from U.S. federal income tax, subject to the possible application of the federal alternative minimum tax.

As a regulated investment company, the Acquiring Fund generally will not be subject to U.S. federal income tax on its investment company taxable income and net capital gain (the excess of net long-term capital gain over net short-term capital loss), if any, that it distributes to shareholders. The Acquiring Fund may retain for investment its net capital gain. However, if the Acquiring Fund retains any net capital gain or any investment company taxable income, it will be subject to tax at regular corporate rates on the amount retained. If the Acquiring Fund retains any net capital gain, it may designate the retained amount as undistributed capital gains in a notice to its shareholders who, if subject to U.S. federal income tax on long-term capital gains, (i) will be required to include in income for U.S. federal income tax purposes, as long-term capital gain, their share of such undistributed amount, and (ii) will be entitled to credit their proportionate shares of the federal income tax paid by

S-53

the Acquiring Fund on such undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds to the extent the credit exceeds such liabilities. For U.S. federal income tax purposes, the basis of shares owned by a shareholder of the Acquiring Fund will be increased by an amount equal to the difference between the amount of undistributed capital gains included in the shareholder’s gross income and the federal income tax deemed paid by the shareholder under clause (ii) of the preceding sentence. The Acquiring Fund intends to distribute to its shareholders, at least annually, substantially all of its investment company taxable income (determined without regard to the deduction for dividends paid) and the net capital gain not otherwise retained by the Acquiring Fund.

Amounts not distributed on a timely basis in accordance with a calendar year distribution requirement are subject to a nondeductible 4% federal excise tax. To prevent imposition of the excise tax, the Acquiring Fund must distribute during each calendar year an amount at least equal to the sum of (1) 98% of its ordinary taxable income (not taking into account any capital gains or losses) for the calendar year, (2) 98.2% of its capital gains in excess of its capital losses (adjusted for certain ordinary losses) for the one-year period ending October 31 of the calendar year, and (3) any ordinary taxable income and capital gains for previous years that were not distributed during those years and on which the Acquiring Fund paid no U.S. federal income tax. To prevent application of the excise tax, the Acquiring Fund intends to make its distributions in accordance with the calendar year distribution requirement.

The Acquiring Fund may acquire municipal obligations and other debt securities that are market discount bonds. A market discount bond is a security acquired in the secondary market at a price below its redemption value (or its adjusted issue price if it is also an original issue discount bond). If the Acquiring Fund invests in a market discount bond, it will be required to treat any gain recognized on the disposition of such market discount bond as ordinary taxable income to the extent of the accrued market discount unless the Acquiring Fund elects to include the market discount in taxable income as it accrues.

If the Acquiring Fund invests in certain taxable pay-in-kind securities, zero coupon securities, deferred interest securities or, in general, any other securities with original issue discount (or with market discount if the Acquiring Fund elects to include market discount in income currently), the Acquiring Fund must accrue income on such investments for each taxable year, which generally will be prior to the receipt of the corresponding cash payments. However, the Acquiring Fund must distribute to shareholders, at least annually, all or substantially all of its investment company taxable income (determined without regard to the deduction for dividends paid) and net tax-exempt interest, including such accrued income, to avoid federal income and excise taxes. Therefore, the Acquiring Fund may have to dispose of its portfolio securities under disadvantageous circumstances to generate cash, or may have to leverage itself by borrowing the cash, to satisfy these distribution requirements.

A portion of the Acquiring Fund’s expenditures that would otherwise be deductible may not be allowed as deductions by reason of the Acquiring Fund’s investment in municipal securities (with such disallowed portion, in general, being the same percentage of the Acquiring Fund’s aggregate expenses as the percentage of the Acquiring Fund’s aggregate income (other than capital gain income) that constitutes exempt-interest income). A similar disallowance rule also applies to interest expense paid or incurred by the Acquiring Fund, if any. Such disallowed deductions, if any, will reduce the amount that the Acquiring Fund can designate as exempt-interest dividends by the disallowed amount. Income distributions by the Acquiring Fund in excess of the amount of the Acquiring Fund’s exempt-interest dividends may be taxable as ordinary income.

S-54

Distributions to shareholders of net investment income received by the Acquiring Fund from taxable temporary investments, if any, and of net short-term capital gains realized by the Acquiring Fund, if any, will be taxable to its shareholders as ordinary income. Distributions by the Acquiring Fund of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss), if any, are taxable as long-term capital gain, regardless of the length of time the shareholder has owned the shares with respect to which such distributions are made. The amount of taxable income allocable to the Acquiring Fund’s shares will depend upon the amount of such income realized by the Acquiring Fund, but is not generally expected to be significant.

Distributions, if any, in excess of the Acquiring Fund’s earnings and profits will first reduce the adjusted tax basis of a shareholder’s shares and, after that basis has been reduced to zero, will constitute capital gain to the shareholder (assuming the shares are held as a capital asset). For taxable years beginning before January 1, 2013, “qualified dividend income” received by noncorporate shareholders is taxed for federal income tax purpose at rates equivalent to long-term capital gain tax rates, which reach a maximum of 15%. Qualified dividend income generally includes dividends from domestic corporations and dividends from non-U.S. corporations that meet certain specified criteria. For taxable years beginning on or after January 1, 2013, qualified dividend income will no longer be taxed at the rates applicable to long-term capital gains, and the maximum individual federal income tax rate on long-term capital gains will increase to 20%, unless Congress enacts legislation providing otherwise. As long as the Acquiring Fund qualifies as a regulated investment company under the Code, it is not expected that any part of its distributions to shareholders from its investments will qualify for the dividends-received deduction available to corporate shareholders or as qualified dividend income in the case of noncorporate shareholders.

Distributions are treated the same for federal income tax purposes whether reinvested in additional shares of the Acquiring Fund or paid in cash.

The IRS currently requires that the Acquiring Fund designate distributions paid with respect to its common shares and its preferred shares as consisting of a portion of each type of income distributed by the Acquiring Fund. The portion of each type of income deemed received by the holders of each class of shares will be equal to the portion of total Acquiring Fund dividends received by such class. Thus, the Acquiring Fund will designate dividends paid as exempt-interest dividends in a manner that allocates such dividends between the holders of the common shares and the preferred shares in proportion to the total dividends paid to each such class during or with respect to the taxable year, or otherwise as required by applicable law. Net capital gain dividends and ordinary income dividends will similarly be allocated between the two classes.

Earnings and profits are generally treated, for federal income tax purposes, as first being used to pay distributions on preferred shares, and then to the extent remaining, if any, to pay distributions on the common shares.

If the Acquiring Fund utilizes leverage through borrowings, or otherwise, asset coverage limitations imposed by the 1940 Act as well as additional restrictions that may be imposed by certain lenders on the payment of dividends or distributions potentially could limit or eliminate the Acquiring Fund’s ability to make distributions on its common shares and/or preferred shares until the asset coverage is restored. These limitations could prevent the Acquiring Fund from distributing at least 90% of its investment company taxable income and tax-exempt interest as is required under the Code and therefore might jeopardize the Acquiring Fund’s qualification as a regulated investment company and/or might subject the Acquiring Fund to a nondeductible 4% federal excise tax. Upon any failure to

S-55

meet the asset coverage requirements imposed by the 1940 Act, the Acquiring Fund may, in its sole discretion and to the extent permitted under the 1940 Act, purchase or redeem preferred shares in order to maintain or restore the requisite asset coverage and avoid the adverse consequences to the Acquiring Fund and its shareholders of failing to meet the distribution requirements. There can be no assurance, however, that any such action would achieve these objectives. The Acquiring Fund endeavors to avoid restrictions on its ability to distribute dividends.

The Code provides that interest on indebtedness incurred or continued to purchase or carry the Acquiring Fund’s shares to which exempt-interest dividends are allocated is not deductible. Under rules used by the IRS for determining when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase or ownership of shares may be considered to have been made with borrowed funds even though such funds are not directly used for the purchase or ownership of such shares.

The interest on private activity bonds in most instances is not federally tax-exempt to a person who is a “substantial user” of a facility financed by such bonds or a “related person” of such “substantial user.” As a result, the Acquiring Fund may not be an appropriate investment for a shareholder who is considered either a “substantial user” or a “related person” within the meaning of the Code. In general, a “substantial user” of a facility includes a “nonexempt person who regularly uses a part of such facility in his trade or business.” “Related persons” are in general defined to include persons among whom there exists a relationship, either by family or business, which would result in a disallowance of losses in transactions among them under various provisions of the Code (or if they are members of the same controlled group of corporations under the Code), including a partnership and each of its partners (and certain members of their families), an S corporation and each of its shareholders (and certain members of their families) and various combinations of these and other relationships. The foregoing is not a complete description of all of the provisions of the Code covering the definitions of “substantial user” and “related person.”

Although dividends generally will be treated as distributed when paid, dividends declared in October, November or December, payable to shareholders of record on a specified date in one of those months and paid during the following January, will be treated as having been distributed by the Acquiring Fund (and received by the shareholders) on December 31 of the year declared.

Certain of the Acquiring Fund’s investment practices are subject to special provisions of the Code that, among other things, may defer the use of certain deductions or losses of the Acquiring Fund, affect the holding period of securities held by the Acquiring Fund and alter the character of the gains or losses realized by the Acquiring Fund. These provisions may also require the Acquiring Fund to recognize income or gain without receiving cash with which to make distributions in the amounts necessary to satisfy the requirements for maintaining regulated investment company status and for avoiding federal income and excise taxes. The Acquiring Fund will monitor its transactions and may make certain tax elections in order to mitigate the effect of these rules and prevent disqualification of the Acquiring Fund as a regulated investment company.

The sale or exchange of shares of the Acquiring Fund normally will result in capital gain or loss to shareholders who hold their shares as capital assets. Generally, a shareholder’s gain or loss will be long-term capital gain or loss if the shares have been held for more than one year even though the increase in value in such shares is attributable to tax-exempt interest income. The gain or loss on shares held for one year or less will generally be treated as short-term capital gain or loss. Present law taxes both long-term and short-term capital gains of corporations at the same rates applicable to ordinary

S-56

income. For non-corporate taxpayers, however, long-term capital gains are currently taxed at a maximum federal income tax rate of 15%, while short-term capital gains and other ordinary income are currently taxed at ordinary income rates. Absent further legislation, the 15% maximum rate applicable to long-term capital gains will increase to 20% for taxable years beginning after December 31, 2012. Any loss on the sale of shares that have been held for six months or less will be disallowed to the extent of any distribution of exempt-interest dividends received with respect to such shares, unless the shares are of a regulated investment company that declares exempt-interest dividends on a daily basis in an amount equal to at least 90% of its net tax-exempt interest and distributes such dividends on a monthly or more frequent basis. If a shareholder sells or otherwise disposes of shares before holding them for more than six months, any loss on the sale or disposition will be treated as a long-term capital loss to the extent of any net capital gain dividends received by the shareholder with respect to such shares. Any loss realized on a sale or exchange of shares of the Acquiring Fund will be disallowed to the extent those shares of the Acquiring Fund are replaced by other substantially identical shares of the Acquiring Fund or other substantially identical stock or securities (including through reinvestment of dividends) within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of the original shares. In that event, the basis of the replacement stock or securities will be adjusted to reflect the disallowed loss.

Federal income tax law imposes an alternative minimum tax with respect to corporations, individuals, trusts and estates. Interest on certain “private activity” bonds is included as an item of tax preference in determining the amount of a taxpayer’s alternative minimum taxable income. To the extent that the Acquiring Fund received income from municipal securities subject to the federal alternative minimum tax, a portion of the dividends paid by the Acquiring Fund, although otherwise exempt from U.S. federal income tax, would be taxable to its shareholders to the extent that their tax liability is determined under the federal alternative minimum tax. The Acquiring Fund will annually provide a report indicating the percentage of the Acquiring Fund’s income attributable to municipal securities subject to the federal alternative minimum tax. In addition, for certain corporations, federal alternative minimum taxable income is increased by 75% of the difference between an alternative measure of income (“adjusted current earnings”) and the amount otherwise determined to be the alternative minimum taxable income. Interest on all municipal securities, and therefore a distribution by the Acquiring Fund that would otherwise be tax-exempt, is included in calculating a corporation’s adjusted current earnings. Certain small corporations are not subject to the federal alternative minimum tax.

For taxable years beginning after December 31, 2012, certain non-corporate shareholders will be subject to an increased rate of tax on some or all of their “net investment income,” which will include items of gross income that are attributable to interest, original issue discount and market discount, as well as net gain from the disposition of other property. This tax will generally apply to the extent net investment income, when added to other modified adjusted gross income, exceeds $200,000 for an unmarried individual, $250,000 for a married taxpayer filing a joint return (or a surviving spouse), or $125,000 for a married individual filing a separate return. Shareholders should consult their tax advisers regarding the applicability of this tax in respect of their shares.

Tax-exempt income, including exempt-interest dividends paid by the Acquiring Fund, is taken into account in calculating the amount of social security and railroad retirement benefits that may be subject to federal income tax.

The Acquiring Fund may be required to withhold U.S. federal income tax from all distributions (including exempt-interest dividends) and redemption proceeds payable to shareholders who fail to

S-57

provide the Acquiring Fund with their correct taxpayer identification number or to make required certifications, or who have been notified by the IRS that they are subject to backup withholding. The backup withholding percentage is 28% for amounts paid through 2012, after which time the rate will increase to 31% absent legislative change. Corporate shareholders and certain other shareholders specified in the Code generally are exempt from such backup withholding. This withholding is not an additional tax. Any amounts withheld may be credited against the shareholder’s federal income tax liability, provided the required information is furnished to the IRS.

The Code provides that every shareholder required to file a tax return must include for information purposes on such return the amount of tax-exempt interest received during the taxable year, including any exempt-interest dividends received from the Acquiring Fund.

PRO FORMA FINANCIAL INFORMATION

The unaudited pro forma financial information set forth below is for informational purposes only and does not purport to be indicative of the financial condition that actually would have resulted if the Reorganizations had been consummated. The closing of the Reorganizations is contingent upon certain conditions being satisfied or waived, including that shareholders of each Fund, voting separately, must approve the Reorganization for their Fund and that shareholders of the Acquiring Fund must approve the issuance of additional common shares of the Acquiring Fund in connection with the Reorganizations. If one Fund does not obtain the requisite approvals, the closing will not occur for any Fund. These pro forma numbers have been estimated in good faith based on information regarding the Acquired Funds and Acquiring Fund as of April 30, 2012. The unaudited pro forma financial information should be read in conjunction with the historical financial statements of the Acquired Funds and the Acquiring Fund, which are available in their respective annual and semi-annual shareholder reports.

Narrative Description of the Pro Forma Effects of the Reorganizations

Note 1 — Reorganization

The unaudited pro forma information has been prepared to give effect to the proposed reorganizations of the Acquired Funds into the Acquiring Fund pursuant to an Agreement and Plan of Reorganization (the “Plan”) as of the beginning of the period indicated below in the table.

Acquired Funds |  | Acquiring Fund |  | 12 Month Period Ended
Nuveen Premier Municipal Opportunity Fund, Inc. (“Premier Opportunity”) |  | Nuveen AMT-Free Municipal Income Fund (“Acquiring Fund”) |  | April 30, 2012
Nuveen Premium Income Municipal Opportunity Fund (“Premium Income”) |  |  |  |

Note 2 — Basis of Pro Forma

Each Reorganization will be accounted for as a tax-free reorganization of investment companies; therefore, no gain or loss will be recognized by the Acquiring Fund or its shareholders as a result of a Reorganization. The Acquired Funds and the Acquiring Fund are registered closed-end management investment companies. The Reorganizations would be accomplished by the acquisition of substantially all of the assets and the assumption of substantially all of the liabilities of the Acquired Funds by the Acquiring Fund in exchange for shares of the Acquiring Fund and the distribution of such shares to Acquired Funds’ shareholders in complete liquidation of the Acquired Funds. The pro forma financial information has been adjusted to reflect the Reorganization costs discussed in Note 4 and the assumption that Premier Opportunity and Premium Opportunity make undistributed net investment income distributions of $3,661,389 and $5,943,679, respectively, to their shareholders prior to the Reorganizations. The table below shows the common shares that Acquired Funds shareholders would have received if the Reorganizations were to have taken place on the period ended date in Note 1.

Acquired Fund |  | Shares Exchanged |
Premier Opportunity |  |  | 19,726,276 |
Premium Opportunity |  |  | 35,002,786 |

S-59

In accordance with accounting principles generally accepted in the United States of America, each Reorganization will be accounted for as a tax-free reorganization for federal income tax purposes. For financial reporting purposes, the historical cost basis of the investments received from each Acquired Fund will be carried forward to align ongoing reporting of the realized and unrealized gains and losses of the surviving fund (which will be the Acquiring Fund) with amounts distributable to shareholders for tax purposes.

Fund |  | Net Assets Applicable to Common Shares |  |  | As-of Date |
Acquiring Fund |  | $ | 338,281,889 |  |  |  | April 30, 2012 |
Premier Opportunity |  | $ | 303,454,344 |  |  |  | April 30, 2012 |
Premium Opportunity |  | $ | 538,363,787 |  |  |  | April 30, 2012 |
Combined Fund Pro Forma |  | $ | 1,169,589,952 |  |  |  | April 30, 2012 |

Note 3 — Pro Forma Expense Adjustments

The table below reflects adjustments to annual expenses made to the Combined Fund Pro Forma financial information as if the Reorganizations had taken place on the first day of the period as disclosed in Note 1. The pro forma information has been derived from the books and records used in calculating daily net asset values of the Acquired Funds and the Acquiring Fund and has been prepared in accordance with accounting principles generally accepted in the United States of America which requires management to make estimates and assumptions that affect this information. Pro forma expenses do not include the expenses to be charged to the Funds in connection with the Reorganizations. Percentages presented below are the increase (decrease) in expenses divided by the Combined Fund Pro Forma Net Assets Applicable to Common Shares presented in Note 2. Actual results could differ from those estimates. No other significant pro forma effects are expected to result from the Reorganizations.

|  | Increase (Decrease) |
Net Expense Category |  | Dollar Amount |  |  | Percentage |
Management fees 1 |  | $ | (309,539 | ) |  |  | (0.03 | )%
Shareholders’ reports – printing and mailing expenses 2 |  | $ | (62,476 | ) |  |  | (0.01 | )%
Professional fees 2 |  | $ | (37,951 | ) |  |  | (0.00 | )%3
Custodian’s fees and expenses 2 |  | $ | (19,584 | ) |  |  | (0.00 | )%3
Total Pro Forma Net Expense Adjustment |  | $ | (429,495 | ) |  |  | (0.04 | )%

(1) | Reflects the impact of applying the Acquiring Fund’s fund-level management fee rates following the Reorganizations to the combined fund’s average managed assets.

(2) | Reflects the anticipated reduction of certain duplicative expenses eliminated as a result of the Reorganizations.

(3) | Rounds to less than (0.01)%.

No significant accounting policies will change as a result of the Reorganizations, specifically policies regarding security valuation or compliance with Subchapter M of the Internal Revenue Code of 1986, as amended. No significant changes to any existing contracts of the Acquiring Fund are expected as a result of the Reorganizations.

S-60

Note 4 — Reorganization Costs

The Reorganization costs (whether or not the Reorganizations are consummated) will be allocated among the Funds. The Reorganization costs are estimated to be $45,000 for Premier Opportunity and $540,000 for Premium Opportunity. These costs represent the estimated nonrecurring expenses of the Acquired Funds in carrying out their obligations under the Plan and consist of management’s estimate of professional services fees, printing costs and mailing charges related to the proposed Reorganizations to be borne by the Acquired Funds. The Acquiring Fund is expected to be charged approximately $320,000 of expenses in connection with the Reorganizations. The pro forma financial information included in Note 2 has been adjusted for any costs related to the Reorganizations to be borne by the Funds. Reorganization costs do not include any commissions that would be incurred due to portfolio realignment.

As of April 30, 2012, neither Acquired Fund held portfolio securities subject to the federal AMT. If the Reorganizations had occurred as of April 30, 2012, the Acquiring Fund would not have been required to dispose of securities of the Acquired Funds in order to comply with its investment policies and restrictions, and would have not sold any material portion (i.e., more than 5% of an Acquired Fund’s assets) of the securities in the Acquired Funds’ portfolios solely as a result of the Reorganizations.

Note 5 — Accounting Survivor

The Acquiring Fund will be the accounting survivor. The surviving fund will have the portfolio management team, portfolio composition, strategies, investment objective, expense structure and policies/restrictions of the Acquiring Fund.

Note 6 — Capital Loss Carryforward

As of April 30, 2012, the Funds had unused capital loss carryforwards available for federal income tax purposes to be applied against future capital gains, if any. If not applied, the capital loss carryforwards will expire as follows:

|  | Acquiring Fund |  |  | Premier Opportunity |  |  | Premium Opportunity |
Expiration Date: |  |  |  |  |  |  |  |  |  |  |  |
October 31, 2013 |  | $ | 3,824,358 |  |  | $ | — |  |  | $ | — |
October 31, 2015 |  | $ | 174,026 |  |  | $ | — |  |  | $ | — |
October 31, 2016 |  | $ | 1,917,479 |  |  | $ | 1,240,117 |  |  | $ | 3,274,999 |
October 31, 2017 |  | $ | — |  |  | $ | — |  |  | $ | 456,587 |

APPENDIX A —

RATINGS OF INVESTMENTS

Standard & Poor’s Ratings Services—A brief description of the applicable Standard & Poor’s Ratings Services LLC, a subsidiary of The McGraw-Hill Companies (“Standard & Poor’s” or “S&P”), rating symbols and their meanings (as published by S&P) follows:

A Standard & Poor’s issue credit rating is a current opinion of the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations, or a specific financial program (including ratings on medium term note programs and commercial paper programs). It takes into consideration the creditworthiness of guarantors, insurers, or other forms of credit enhancement on the obligation and takes into account the currency in which the obligation is denominated. The issue credit rating is not a recommendation to purchase, sell, or hold a financial obligation, inasmuch as it does not comment as to market price or suitability for a particular investor.

Issue credit ratings are based on current information furnished by the obligors or obtained by Standard & Poor’s from other sources it considers reliable. Standard & Poor’s does not perform an audit in connection with any credit rating and may, on occasion, rely on unaudited financial information. Credit ratings may be changed, suspended, or withdrawn as a result of changes in, or unavailability of, such information, or based on other circumstances.

Issue credit ratings can be either long-term or short-term. Short-term ratings are generally assigned to those obligations considered short-term in the relevant market. In the U.S., for example, that means obligations with an original maturity of no more than 365 days—including commercial paper.

Short-term ratings are also used to indicate the creditworthiness of an obligor with respect to put features on long-term obligations. The result is a dual rating, in which the short-term rating addresses the put feature, in addition to the usual long-term rating. Medium-term notes are assigned long-term ratings.

Long-Term Issue Credit Ratings

Issue credit ratings are based in varying degrees, on the following considerations:

1. Likelihood of payment capacity and willingness of the obligor to meet its financial commitment on an obligation in accordance with the terms of the obligation;

2. Nature of and provisions of the obligation; and

3. Protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization, or other arrangement under the laws of bankruptcy and other laws affecting creditors’ rights.

The issue ratings definitions are expressed in terms of default risk. As such, they pertain to senior obligations of an entity. Junior obligations are typically rated lower than senior obligations, to reflect the lower priority in bankruptcy, as noted above. (Such differentiation applies when an entity has both senior and subordinated obligations, secured and unsecured obligations, or operating company and holding company obligations.) Accordingly, in the case of junior debt, the rating may not conform exactly with the category definition.

A-1

AAA

An obligation rated ‘AAA’ has the highest rating assigned by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA

An obligation rated ‘AA’ differs from the highest-rated obligations only in small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

A

An obligation rated ‘A’ is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

BBB

An obligation rated ‘BBB’ exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

BB, B, CCC, CC, and C

Obligations rated ‘BB’, ‘B’, ‘CCC’, ‘CC’, and ‘C’ are regarded as having significant speculative characteristics. ‘BB’ indicates the least degree of speculation and ‘C’ the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB

An obligation rated ‘BB’ is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions, which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.

B

An obligation rated ‘B’ is more vulnerable to nonpayment than obligations rated ‘BB’, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor’s capacity or willingness to meet its financial commitment on the obligation.

CCC

An obligation rated ‘CCC’ is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

A-2

CC

An obligation rated ‘CC’ is currently highly vulnerable to nonpayment.

C

A Subordinated debt or preferred stock obligation rated ‘C’ is CURRENTLY HIGHLY VULNERABLE to nonpayment. The ‘C’ rating may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on this obligation are being continued. A ‘C’ also will be assigned to a preferred stock issue in arrears on dividends or sinking fund payments, but that is currently paying.

D

An obligation rated ‘D’ is in payment default. The ‘D’ rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless Standard & Poor’s believes that such payments will be made during such grace period. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Plus (+) or minus (-). The ratings from ‘AA’ to ‘CCC’ may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

r

This symbol is attached to the ratings of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating.

N.R.

This indicates that no rating has been requested, that there is insufficient information on which to base a rating, or that Standard & Poor’s does not rate a particular obligation as a matter of policy.

Short-Term Issue Credit Ratings

A-1

A short-term obligation rated ‘A-1’ is rated in the highest category by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2

A short-term obligation rated ‘A-2’ is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

A-3

A-3

A short-term obligation rated ‘A-3’ exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

B

A short-term obligation rated ‘B’ is regarded as having significant speculative characteristics. The obligor currently has the capacity to meet its financial commitment on the obligation; however, it faces major ongoing uncertainties which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.

C

A short-term obligation rated ‘C’ is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation.

D

A short-term obligation rated ‘D’ is in payment default. The ‘D’ rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless Standard & Poor’s believes that such payments will be made during such grace period. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Moody’s Investors Service, Inc.—A brief description of the applicable Moody’s Investors Service, Inc. (“Moody’s”) rating symbols and their meanings (as published by Moody’s) follows:

Municipal Bonds

Aaa

Bonds that are rated ‘Aaa’ are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Aa

Bonds that are rated ‘Aa’ are judged to be of high quality by all standards. Together with the ‘Aaa’ group they comprise what are generally known as high grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in ‘Aaa’ securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present that make the long-term risks appear somewhat larger than in ‘Aaa’ securities.

A-4

A

Bonds that are rated ‘A’ possess many favorable investment attributes and are to be considered as upper medium grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

Baa

Bonds that are rated ‘Baa’ are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact have speculative characteristics as well.

Ba

Bonds that are rated ‘Ba’ are judged to have speculative elements; their future cannot be considered as well assured. Often the protection of interest and principal payments may be very moderate and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B

Bonds that are rated ‘B’ generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

Caa

Bonds that are rated ‘Caa’ are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

Ca

Bonds that are rated ‘Ca’ represent obligations that are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C

Bonds that are rated ‘C’ are the lowest rated class of bonds, and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

#(hatchmark): Represents issues that are secured by escrowed funds held in cash, held in trust, invested and reinvested in direct, non-callable, non-prepayable United States government obligations or non-callable, non-prepayable obligations unconditionally guaranteed by the U.S. Government, Resolution Funding Corporation debt obligations.

Con. (…): Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of

A-5

projects under construction, (b) earnings of projects unseasoned in operation experience, (c) rentals that begin when facilities are completed, or (d) payments to which some other limiting condition attaches. The parenthetical rating denotes probable credit stature upon completion of construction or elimination of the basis of the condition.

(P): When applied to forward delivery bonds, indicates the rating is provisional pending delivery of the bonds. The rating may be revised prior to delivery if changes occur in the legal documents or the underlying credit quality of the bonds.

Note: Moody’s applies numerical modifiers 1, 2 and 3 in each generic rating classification from Aa through Caa. The modifier 1 indicates that the issue ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that the issue ranks in the lower end of its generic rating category.

Short-Term Loans

MIG 1/VMIG 1

This designation denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support, or demonstrated broad-based access to the market for refinancing.

MIG 2/VMIG 2

This designation denotes strong credit quality. Margins of protection are ample, although not as large as in the preceding group.

MIG 3/VMIG 3

This designation denotes acceptable credit quality. Liquidity and cash-flow protection may be narrow, and market access for refinancing is likely to be less well-established.

SG

This designation denotes speculative-grade credit quality. Debt instruments in this category may lack sufficient margins of protection.

Commercial Paper

Issuers (or supporting institutions) rated Prime-1 have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will normally be evidenced by the following characteristics:

| — |  | Leading market positions in well-established industries.

| — |  | High rates of return on funds employed.

| — |  | Conservative capitalization structures with moderate reliance on debt and ample asset protection.

A-6

| — |  | Broad margins in earnings coverage of fixed financial charges and high internal cash generation.

| — |  | Well-established access to a range of financial markets and assured sources of alternate liquidity.

Issuers (or supporting institutions) rated Prime-2 have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above but to a lesser degree. Earnings trends and coverage ratios, while sound, may be more subject to variation than is the case for Prime-2 securities. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Issuers (or supporting institutions) rated Prime-3 have an acceptable ability for repayment of senior short-term debt obligations. The effect of industry characteristics and market composition may be more pronounced. Variability in earnings and profitability may result in changes in the level of debt protection measurements and the requirement for relatively high financial leverage. Adequate alternate liquidity is maintained.

Issuers rated Not Prime do not fall within any of the Prime rating categories.

Fitch, Inc.—A brief description of the applicable Fitch, Inc. (“Fitch”) ratings symbols and meanings (as published by Fitch) follows:

Long-Term Credit Ratings

Investment Grade

AAA

Highest credit quality. ‘AAA’ ratings denote the lowest expectation of credit risk. They are assigned only in case of exceptionally strong capacity for timely payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

AA

Very high credit quality. ‘AA’ ratings denote a very low expectation of credit risk. They indicate very strong capacity for timely payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A

High credit quality. ‘A’ ratings denote a low expectation of credit risk. The capacity for timely payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to changes in circumstances or in economic conditions than is the case for higher ratings.

BBB

Good credit quality. ‘BBB’ ratings indicate that there is currently a low expectation of credit risk. The capacity for timely payment of financial commitments is considered adequate, but adverse changes in circumstances and in economic conditions are more likely to impair this capacity. This is the lowest investment-grade category.

A-7

Speculative Grade

BB

Speculative. ‘BB’ ratings indicate that there is a possibility of credit risk developing, particularly as the result of adverse economic change over time; however, business or financial alternatives may be available to allow financial commitments to be met. Securities rated in this category are not investment grade.

B

Highly speculative. ‘B’ ratings indicate that significant credit risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, capacity for continued payment is contingent upon a sustained, favorable business and economic environment.

CCC, CC, C

High default risk. Default is a real possibility. Capacity for meeting financial commitments is solely reliant upon sustained, favorable business or economic developments. A ‘CC’ rating indicates that default of some kind appears probable. ‘C’ ratings signal imminent default.

DDD, DD, and D Default

The ratings of obligations in this category are based on their prospects for achieving partial or full recovery in a reorganization or liquidation of the obligor. While expected recovery values are highly speculative and cannot be estimated with any precision, the following serve as general guidelines. ‘DDD’ obligations have the highest potential for recovery, around 90%-100% of outstanding amounts and accrued interest. ‘DD’ indicates potential recoveries in the range of 50%-90%, and ‘D’ the lowest recovery potential, i.e., below 50%. Entities rated in this category have defaulted on some or all of their obligations. Entities rated ‘DDD’ have the highest prospect for resumption of performance or continued operation with or without a formal reorganization process. Entities rated ‘DD’ and ‘D’ are generally undergoing a formal reorganization or liquidation process; those rated ‘DD’ are likely to satisfy a higher portion of their outstanding obligations, while entities rated ‘D’ have a poor prospect for repaying all obligations.

Short-Term Credit Ratings

A short-term rating has a time horizon of less than 12 months for most obligations, or up to three years for U.S. public finance securities, and thus places greater emphasis on the liquidity necessary to meet financial commitments in a timely manner.

F1

Highest credit quality. Indicates the strongest capacity for timely payment of financial commitments; may have an added “+” to denote any exceptionally strong credit feature.

F2

Good credit quality. A satisfactory capacity for timely payment of financial commitments, but the margin of safety is not as great as in the case of the higher ratings.

A-8

F3

Fair credit quality. The capacity for timely payment of financial commitments is adequate; however, near-term adverse changes could result in a reduction to non-investment grade. B Speculative. Minimal capacity for timely payment of financial commitments, plus vulnerability to near-term adverse changes in financial and economic conditions.

B

Speculative Minimal capacity for timely payment of financial commitments, plus vulnerability to near-term adverse changes in financial and economic conditions.

C

High default risk. Default is a real possibility. Capacity for meeting financial commitments is solely reliant upon a sustained, favorable business and economic environment.

D

Default. Denotes actual or imminent payment default.

Notes to Long-term and Short-term ratings:

“+” or “-” may be appended to a rating to denote relative status within major rating categories. Such suffixes are not added to the ‘AAA’ Long-term rating category, to categories below ‘CCC’, or to Short-term ratings other than ‘F1’.

‘NR’ indicates that Fitch Ratings does not rate the issuer or issue in question.

‘Withdrawn’: A rating is withdrawn when Fitch Ratings deems the amount of information available to be inadequate for rating purposes, or when an obligation matures, is called, or refinanced.

Rating Watch: Ratings are placed on Rating Watch to notify investors that there is a reasonable probability of a rating change and the likely direction of such change. These are designated as “Positive”, indicating a potential upgrade, “Negative”, for a potential downgrade, or “Evolving”, if ratings may be raised, lowered or maintained. Rating Watch is typically resolved over a relatively short period.

A Rating Outlook indicates the direction a rating is likely to move over a one to two year period. Outlooks may be positive, stable, or negative. A positive or negative Rating Outlook does not imply a rating change is inevitable. Similarly, ratings for which outlooks are ‘stable’ could be downgraded before an outlook moves to positive or negative if circumstances warrant such an action. Occasionally, Fitch Ratings may be unable to identify the fundamental trend. In these cases, the Rating Outlook may be described as evolving.

Chairman’s

Letter to Shareholders

Dear Shareholders,

These are perplexing times for investors. The global economy continues to struggle. The solutions being implemented in the eurozone to deal with the debt crises of many of its member countries are not yet seen as sufficient by the financial markets. The political paralysis in the U.S. has prevented the compromises necessary to deal with the fiscal imbalance and government spending priorities. The efforts by individual consumers, governments and financial institutions to reduce their debts are increasing savings but reducing demand for the goods and services that drive employment. These developments are undermining the rebuilding of confidence by consumers, corporations and investors that is so essential to a resumption of economic growth.

Although it is painfully slow, progress is being made. In Europe, the turnover of a number of national governments reflects the realization by politicians and voters alike that leaders who practiced business as usual had to be replaced by leaders willing to face problems and accept the hard choices needed to resolve them. The recent coordinated efforts by central banks in the U.S. and Europe to provide liquidity to the largest European banks indicates that these monetary authorities are committed to facilitating a recovery in the European banking sector.

In the U.S., the failure of the congressionally appointed Debt Reduction Committee was a blow to those who hoped for a bipartisan effort to finally begin addressing the looming fiscal crisis. Nevertheless, Congress and the administration cannot ignore the issue for long. The Bush era tax cuts are scheduled to expire on December 31, 2012, and six months later the $1.2 trillion of mandatory across-the-board spending cuts under the Budget Control Act of 2011 begin to go into effect. Any legislative modification would require bipartisan support and the prospects for a bipartisan solution are unclear. The impact of these two developments would be a mixed blessing: a meaningful reduction in the annual budget deficit at the cost of slowing the economic recovery.

It is in these particularly volatile markets that professional investment management is most important. Skillful investment teams who have experienced challenging markets and remain committed to their investment disciplines are critical to the success of an investor’s long-term objectives. In fact, many long-term investment track records are built during challenging markets when managers are able to protect investors against these economic crosscurrents. Experienced investment teams know that volatile markets put a premium on companies and investment ideas that will weather the short-term volatility and that compelling values and opportunities are opened up when markets overreact to negative developments. By maintaining appropriate time horizons, diversification and relying on practiced investment teams, we believe that investors can achieve their long-term investment objectives.

As always, I encourage you to contact your financial consultant if you have any questions about your investment in a Nuveen Fund. On behalf of the other members of your Fund Board, we look forward to continuing to earn your trust in the months and years ahead.

Sincerely,

Robert P. Bremner

Chairman of the Board

Nuveen Insured Municipal Opportunity Fund, Inc. (NIO)

Nuveen Premier Insured Municipal Income Fund, Inc. (NIF)

Nuveen Insured Premium Income Municipal Fund 2 (NPX)

Nuveen Insured Dividend Advantage Municipal Fund (NVG)

Nuveen Insured Tax-Free Advantage Municipal Fund (NEA)

Portfolio managers Paul Brennan and Douglas White review key investment strategies and the twelve-month performance of these six national insured Funds. With 20 years of industry experience, including 14 years at Nuveen, Paul has managed NIO, NIF, NVG and NEA since 2006. Douglas, who has 28 years of financial industry experience, assumed portfolio management responsibility for NQI and NPX from Paul in January 2011.

What factors affected the U.S. economy and municipal market during the twelve-month reporting period ended October 31, 2011?

During this period, the U.S. economy’s recovery from recession remained slow. The Federal Reserve (Fed) maintained its efforts to improve the overall economic environment by continuing to hold the benchmark fed funds rate at the record low level of zero to 0.25% that it had established in December 2008. At its November 2011 meeting (shortly after the end of this reporting period), the central bank reaffirmed its opinion that economic conditions would likely warrant keeping this rate at “exceptionally low levels” at least through mid-2013. The Fed also said that it would continue its program to extend the average maturity of its holdings of U.S. Treasury securities by purchasing $400 billion of U.S. Treasury securities with maturities of six to thirty years and selling an equal amount of U.S. Treasury securities with maturities of three years or less. The goals of this program, which the Fed expects to complete by the end of June 2012, are to lower longer-term interest rates, support a stronger economic recovery and help ensure that inflation remains at levels consistent with the Fed’s mandates of maximum employment and price stability.

In the third quarter of 2011, the U.S. economy, as measured by the U.S. gross domestic product (GDP), grew at an annualized rate of 2.0%, the best growth number since the fourth quarter of 2010 and the ninth consecutive quarter of positive growth. The Consumer Price Index (CPI) rose 3.5% year-over-year as of October 2011, while the core CPI (which excludes food and energy) increased 2.1%, edging just above the Fed’s unofficial objective of 2.0% or lower for this inflation measure. Unemployment numbers remained high, as October 2011 marked the seventh straight month with a national jobless number of 9.0% or higher. However, after the reporting period came to a close, the U.S. unemployment rate fell to 8.6% in November 2011. While the dip was a step in

the right direction, it was due partly to a number of individuals dropping out of the hunt for work. The housing market also continued to be a major weak spot. For the twelve months ended September 2011 (the most recent data available at the time this report was prepared), the average home price in the Standard & Poor’s/Case-Shiller Index lost 3.6%, with 18 of the 20 major metropolitan areas reporting losses. In addition, the U.S. economic picture continued to be clouded by concerns about the European debt crisis and efforts to reduce the federal deficit.

Municipal bond prices ended this period generally unchanged versus the beginning of this reporting period, masking a sell-off that commenced in the fourth quarter of 2010, as the result of investor concerns about inflation, the federal deficit and its impact on demand for U.S. Treasuries. Adding to this situation was media coverage of the strained finances of many state and local governments, which failed to differentiate between gaps in these governments’ operating budgets and their ability to meet their debt service obligations. As a result, money flowed out of municipal mutual funds, yields rose, and valuations declined.

During the second half of this reporting period (i.e., May-October 2011), municipal bond prices generally rallied as yields declined across the municipal curve. The decline in yields was due in part to the continued depressed level of municipal bond issuance. Tax-exempt volume, which had been limited in 2010 by issuers’ extensive use of taxable Build America Bonds (BABs), continued to drift lower in 2011. Even though BABs were no longer an option for issuers (the BAB program expired at the end of 2010), some borrowers had accelerated issuance into 2010 in order to take advantage of the program’s favorable terms before its termination, fulfilling their capital program borrowing needs well into 2012. This reduced the need for many borrowers to come to market with new issues during this period. Over the twelve months ended October 31, 2011, municipal bond issuance nationwide totaled $320.2 billion, a decrease of 23% compared with the issuance of the twelve-month period ended October 31, 2010. During the majority of this period, demand for municipal bonds remained very strong.

What key strategies were used to manage these Funds during this reporting period?

During this period, finding appropriate insured bonds, especially new insured issues, remained a challenge due to the continued severe decline in insured issuance. Over the past few years, most municipal bond insurers had their credit ratings downgraded, and only one insurer currently insures new municipal bonds. As a result, the supply of insured municipal securities has decreased dramatically. Over the past ten months of 2011, issuance of new insured bonds totaled $12.2 billion, or just 5% of total municipal issuance (compared with a recent historical average of 50%), down 47% from the ten months ended October 2010. Even though these Funds may now invest up to 20% of their net assets in uninsured investment-grade credits rated BBB- or higher, the combination of tighter municipal supply, little insured issuance and relatively lower yields meant fewer attractive opportunities for these Funds during this period.

In this environment, we took an opportunistic approach to discovering what we thought were undervalued sectors and individual credits with the potential to perform well over the long term. During this period, all of the Funds found value in the essential services

sectors such as water and sewer, and NIO, NIF, NVG and NEA also added tax-supported bonds backed by excise taxes and other limited tax obligations. In NQI and NPX, we found opportunities in the secondary market to purchase health care, transportation (specifically airports and highway revenue bonds) and higher education credits. Overall, our focus remained on high quality investments. We also emphasized purchasing bonds with longer maturities in order to take advantage of more attractive yields at the longer end of the municipal yield curve. The purchase of longer bonds also extended the Funds’ durations, which helped maintain their yield curve positioning.

Cash for new purchases during this period was generated largely by the proceeds from called and maturing bonds, which we worked to redeploy to keep the Funds fully invested. Most of the Funds also selectively sold bonds with short maturities or short call dates in advance of their maturity or call dates to generate additional funds that enabled them to take advantage of attractive purchase candidates as they became available in the market.

As of October 31, 2011, all of these Funds continued to use inverse floating rate securities. We employ inverse floaters for a variety of reasons, including duration management, income enhancement and total return enhancement.

How did the Funds perform?

Individual results for these Funds, as well as relevant index and peer group information, are presented in the accompanying table.

Lipper General and Insured Leveraged Municipal Debt Funds Classification Average* |  |  | 4.80% |  |  |  | 4.20% |  |  |  | 5.59% |

For the twelve months ended October 31, 2011, the total returns on common share net asset value (NAV) for NQI, NIO, NIF, NPX and NVG exceeded the return for the Standard & Poor’s (S&P) National Insured Municipal Bond Index, while NEA underperformed this index. For this same period, NQI, NPX and NVG outperformed the Lipper General and Insured Leveraged Municipal Debt Funds Classification Average, while NIO, NIF and NEA lagged the Lipper average.

Key management factors that influenced the Funds’ returns during this period included duration and yield curve positioning, credit exposure and sector allocation. In addition, the Funds’ use of leverage was an important positive factor affecting the Funds’ performance over this period. The impact of structural leverage is discussed in more detail later in this report.

|  | Nuveen Investments |  | 7

During this period, municipal bonds with intermediate and longer maturities tended to outperform the short maturity categories, with credits having maturities of seven years and longer generally outpacing the market. Among these Funds, NQI and NPX were the most advantageously situated in terms of duration and yield curve positioning, with more exposure to the longer parts of the yield curve that performed well. In general during this period, the greater a Fund’s exposure to the outperforming intermediate and longer parts of the curve, the greater the positive impact on the Fund’s return. The remaining four Funds, especially NEA, had shorter durations, which hampered their performance in the market environment of the period. Both NVG and NEA, which were introduced in 2002, are approaching their 10-year anniversaries and therefore have the increased exposure to bonds with short call dates often associated with that milestone.

Credit exposure also played a role in performance, as bonds rated A and AA typically outperformed the other credit quality categories. On the whole, bonds with higher levels of credit risk were not favored by the market during this period. The performance of the BBB category, in particular, was dragged down by poor returns in the tobacco bond sector (bonds backed by the 1998 master tobacco settlement agreement). All of these Funds benefited from their strong weightings in the A and AA sectors, while the negative impact of their BBB rated holdings was limited by the Funds’ modest exposures to this category.

Holdings that generally made positive contributions to the Funds’ returns during this period included zero coupon bonds and housing, water and sewer, and health care credits. General obligation and other tax-supported bonds also generally outpaced the municipal market return for the twelve months. All of these Funds, particularly NQI, benefited from their exposure to the health care sector. Holdings in the transportation sector also performed well, with NVG having the heaviest weighting in this sector and NEA the smallest. On the whole, some of the best performing bonds in the Funds’ portfolios for this period were those purchased during the earlier part of this period before the market rallied, when yields were relatively higher and prices especially attractive.

In contrast, pre-refunded bonds, which are often backed by U.S. Treasury securities, were among the poorest performing market segments during this period. The under-performance of these bonds can be attributed primarily to their shorter effective maturities and higher credit quality. Among these six Funds, NEA, NVG and NIF held the heaviest allocations of pre-refunded bonds, while NQI had the smallest exposure to these bonds.

FUND POLICY CHANGES

On October 28, 2011, the Funds’ Board of Directors/Trustees approved changes to each Fund’s investment policy regarding its investment in insured municipal securities. These changes are designed to provide the Adviser with more flexibility regarding the types of securities available for investment by each Fund.

Effective January 2, 2012, each Fund will eliminate the investment policy requiring it, under normal circumstances, to invest at least 80% of its managed assets in municipal securities that are covered by insurance guaranteeing the timely payment of principal and interest. Over the past few years, most municipal bond insurers have had their credit ratings downgraded and only one insurer is currently insuring new municipal bonds. As a result, the supply of insured municipal securities has decreased dramatically and the long-term viability of the municipal bond insurance market is uncertain. The Funds are not changing their investment objective and will continue to invest substantially all of their assets in a portfolio of investment grade quality municipal securities.

Concurrent with the investment policy changes, the Funds will change their names as follows:

• | Nuveen Insured Quality Municipal Fund, Inc. (NQI) will change to Nuveen Quality Municipal Fund, Inc. (NQI)

• | Nuveen Insured Municipal Opportunity Fund, Inc. (NIO) will change to Nuveen Municipal Opportunity Fund, Inc. (NIO)

• | Nuveen Premier Insured Municipal Income Fund, Inc. (NIF) will change to Nuveen Premier Municipal Opportunity Fund, Inc. (NIF)

• | Nuveen Insured Premium Income Municipal Fund 2 (NPX) will change to Nuveen Premium Income Municipal Opportunity Fund (NPX)

• | Nuveen Insured Dividend Advantage Municipal Fund (NVG) will change to Nuveen Dividend Advantage Municipal Income Fund (NVG)

• | Nuveen Insured Tax-Free Advantage Municipal Fund (NEA) will change to Nuveen AMT-Free Municipal Income Fund (NEA)

Fund Leverage and

Other Information

IMPACT OF THE FUNDS’ LEVERAGE STRATEGIES ON PERFORMANCE

One important factor impacting the returns of all these Funds relative to the comparative indexes was the Funds’ use of leverage. The Funds use leverage because their managers believe that, over time, leveraging provides opportunities for additional income and total return for common shareholders. However, use of leverage also can expose common shareholders to additional volatility. For example, as the prices of securities held by a Fund decline, the negative impact of these valuation changes on common share net asset value and common shareholder total return is magnified by the use of leverage. Conversely, leverage may enhance common share returns during periods when the prices of securities held by a Fund generally are rising. Leverage made a positive contribution to the performance of these Funds over this reporting period.

RECENT DEVELOPMENTS REGARDING THE FUNDS’ REDEMPTION OF AUCTION RATE PREFERRED SHARES

Shortly after their respective inceptions, each of the Funds issued auction rate preferred shares (ARPS) to create structural leverage. As noted in past shareholder reports, the ARPS issued by many closed-end funds, including these Funds, have been hampered by a lack of liquidity since February 2008. Since that time, more ARPS have been submitted for sale in each of their regularly scheduled auctions than there have been offers to buy. In fact, offers to buy have been almost completely nonexistent since late February 2008. This means that these auctions have “failed to clear,” and that many, or all, of the ARPS shareholders who wanted to sell their shares in these auctions were unable to do so. This lack of liquidity in ARPS did not lower the credit quality of these shares, and ARPS shareholders unable to sell their shares continued to receive distributions at the “maximum rate” applicable to failed auctions, as calculated in accordance with the pre-established terms of the ARPS. In the recent market, with short term rates at multi-generational lows, those maximum rates also have been low.

One continuing implication for common shareholders from the auction failures is that each Fund’s cost of leverage likely has been incrementally higher at times than it otherwise might have been had the auctions continued to be successful. As a result, each Fund’s common share earnings likely have been incrementally lower at times than they otherwise might have been.

10 |  | Nuveen Investments |  |

As noted in past shareholder reports, the Nuveen funds’ Board of Directors/Trustees authorized several methods that can be used separately or in combination to refinance a portion of the Nuveen funds’ outstanding ARPS. Some funds have utilized tender option bonds (TOBs), also known as inverse floating rate securities, for leverage purposes. The amount of TOBs that a fund may use varies according to the composition of each fund’s portfolio. Some funds have a greater ability to use TOBs than others. Some funds have issued Variable Rate Demand Preferred (VRDP) Shares or Variable Rate MuniFund Term Preferred (VMTP) Shares, which are a floating rate form of preferred stock with a mandatory term redemption. Some funds have issued MuniFund Term Preferred (MTP) Shares, a fixed rate form of preferred stock with a mandatory redemption period of three to five years.

During 2010 and 2011, certain Nuveen leveraged closed-end funds (including NQI, NIO, NIF, NVG and NEA) received a demand letter from a law firm on behalf of purported holders of common shares of each such fund, alleging that Nuveen and the funds’ officers and Board of Directors/Trustees breached their fiduciary duties related to the redemption at par of the funds’ ARPS. In response, the Board established an ad hoc Demand Committee consisting of certain of its disinterested and independent Board members to investigate the claims. The Demand Committee retained independent counsel to assist it in conducting an extensive investigation. Based upon its investigation, the Demand Committee found that it was not in the best interests of each fund or its shareholders to take the actions suggested in the demand letters, and recommended that the full Board reject the demands made in the demand letters. After reviewing the findings and recommendation of the Demand Committee, the full Board of each fund unanimously adopted the Demand Committee’s recommendation.

Subsequently, 33 of the funds that received demand letters (including NQI, NIF, NVG and NEA) were named in a consolidated complaint as nominal defendants in a putative shareholder derivative action captioned Martin Safier, et al. v. Nuveen Asset Management, et al. that was filed in the Circuit Court of Cook County, Illinois, Chancery Division (the “Cook County Chancery Court”) on February 18, 2011 (the “Complaint”). The Complaint, filed on behalf of purported holders of each fund’s common shares, also name Nuveen Fund Advisors, Inc. as a defendant, together with current and former Officers and interested Director/Trustees of each of the funds (together with the nominal defendants, collectively, the “Defendants”). The Complaint contains the same basic allegations contained in the demand letters. The suits seek a declaration that the Defendants have breached their fiduciary duties, an order directing the Defendants not to redeem any ARPS at their liquidation value using fund assets, indeterminate monetary damages in favor of the funds and an award of plaintiffs’ costs and disbursements in pursuing the action. The Defendants filed a motion to dismiss the suit and on December 16, 2011, the court granted that motion dismissing the Complaint with prejudice.

Regulatory Matters

During May 2011, Nuveen Securities, LLC, known as Nuveen Investments, LLC prior to April 30, 2011, entered into a settlement with the Financial Industry Regulatory Authority (FINRA) with respect to certain allegations regarding Nuveen-sponsored closed-end fund ARPS marketing brochures. As part of this settlement, Nuveen Securities, LLC neither admitted to nor denied FINRA’s allegations. Nuveen is the broker-dealer subsidiary of Nuveen Investments. The settlement with FINRA concludes an investigation that followed the widespread failure of auctions for ARPS and other auction rate securities, which generally began in mid-February 2008. In the settlement, FINRA alleged that certain marketing materials provided by Nuveen Securities, LLC were false and misleading. Nuveen Securities, LLC agreed to a censure and the payment of a $3 million fine.

RISK CONSIDERATIONS

Fund shares are not guaranteed or endorsed by any bank or other insured depository institution, and are not federally insured by the Federal Deposit Insurance Corporation. Past performance is no guarantee of future results. Fund common shares are subject to a variety of risks, including:

Investment Risk. The possible loss of the entire principal amount that you invest.

Price Risk. Shares of closed-end investment companies like these Funds frequently trade at a discount to their NAV. Your common shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions.

Leverage Risk. Each Fund’s use of leverage creates the possibility of higher volatility for the Fund’s per share NAV, market price, distributions and returns. There is no assurance that a Fund’s leveraging strategy will be successful.

Tax Risk. The tax treatment of Fund distributions may be affected by new IRS interpretations of the Internal Revenue Code and future changes in tax laws and regulations.

Issuer Credit Risk. This is the risk that a security in a Fund’s portfolio will fail to make dividend or interest payments when due.

Interest Rate Risk. Fixed-income securities such as bonds, preferred, convertible and other debt securities will decline in value if market interest rates rise.

Reinvestment Risk. If market interest rates decline, income earned from a Fund’s portfolio may be reinvested at rates below that of the original bond that generated the income.

Call Risk or Prepayment Risk. Issuers may exercise their option to prepay principal earlier than scheduled, forcing a Fund to reinvest in lower-yielding securities.

Common Share Dividend and

Share Price Information

During the twelve-month reporting period ended October 31, 2011, NQI, NIO, NIF, NVG and NEA each had one monthly dividend increase, while the monthly dividend of NPX remained stable throughout the reporting period.

Due to normal portfolio activity, common shareholders of the following Funds received capital gains and/or net ordinary income distributions in December 2010 as follows:

Fund |  | Long-Term Capital Gains (per share) |  |  | Short-Term Capital Gains and/or Ordinary Income (per share) |
NIO |  |  | — |  |  |  | $0.0044 |
NVG |  |  | $0.0029 |  |  |  | — |

All of the Funds in this report seek to pay stable dividends at rates that reflect each Fund’s past results and projected future performance. During certain periods, each Fund may pay dividends at a rate that may be more or less than the amount of net investment income actually earned by the Fund during the period. If a Fund has cumulatively earned more than it has paid in dividends, it holds the excess in reserve as undistributed net investment income (UNII) as part of the Fund’s NAV. Conversely, if a Fund has cumulatively paid dividends in excess of its earnings, the excess constitutes negative UNII that is likewise reflected in the Fund’s NAV. Each Fund will, over time, pay all of its net investment income as dividends to shareholders. As of October 31, 2011, all of the Funds in this report had positive UNII balances for both tax and financial reporting purposes.

We have audited the accompanying statements of assets and liabilities, including the portfolios of investments, of Nuveen Insured Quality Municipal Fund, Inc., Nuveen Insured Municipal Opportunity Fund, Inc., Nuveen Premier Insured Municipal Income Fund, Inc., Nuveen Insured Premium Income Municipal Fund 2, Nuveen Insured Dividend Advantage Municipal Fund, and Nuveen Insured Tax-Free Advantage Municipal Fund (the “Funds”) as of October 31, 2011, and the related statements of operations and cash flows for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Funds’ internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Funds’ internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2011, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial positions of Nuveen Insured Quality Municipal Fund, Inc., Nuveen Insured Municipal Opportunity Fund, Inc., Nuveen Premier Insured Municipal Income Fund, Inc., Nuveen Insured Premium Income Municipal Fund 2, Nuveen Insured Dividend Advantage Municipal Fund, and Nuveen Insured Tax-Free Advantage Municipal Fund at October 31, 2011, and the results of their operations and their cash flows for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended in conformity with U.S. generally accepted accounting principles.

(a) | The amounts shown are based on Common share equivalents.

(b) | Total Return Based on Market Value is the combination of changes in the market price per share and the effect of reinvested dividend income and reinvested capital gains distributions, if any, at the average price paid per share at the time of reinvestment. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last dividend declared in the period may take place over several days, and in some instances may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation. Total returns are not annualized.

| Total Return Based on Common Share Net Asset Value is the combination of changes in Common share net asset value, reinvested dividend income at net asset value and reinvested capital gains distributions at net asset value, if any. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending net asset value. The actual reinvest price for the last dividend declared in the period may often be based on the Fund’s market price (and not its net asset value), and therefore may be different from the price used in the calculation. Total returns are not annualized.

1. General Information and Significant Accounting Policies

General Information

The funds covered in this report and their corresponding Common share stock exchange symbols are Nuveen Insured Quality Municipal Fund, Inc. (NQI), Nuveen Insured Municipal Opportunity Fund, Inc. (NIO), Nuveen Premier Insured Municipal Income Fund, Inc. (NIF), Nuveen Insured Premium Income Municipal Fund 2 (NPX), Nuveen Insured Dividend Advantage Municipal Fund (NVG) and Nuveen Insured Tax-Free Advantage Municipal Fund (NEA) (each a “Fund” and collectively, the “Funds”). Common shares of Insured Quality (NQI), Insured Opportunity (NIO), Premier Insured Income (NIF) and Insured Premium Income 2 (NPX) are traded on the New York Stock Exchange (“NYSE”) while Common shares of Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage (NEA) are traded on the NYSE Amex. The Funds are registered under the Investment Company Act of 1940, as amended, as closed-end registered investment companies.

Effective January 1, 2011, the Funds’ adviser, Nuveen Asset Management, a wholly-owned subsidiary of Nuveen Investments, Inc. (“Nuveen”), changed its name to Nuveen Fund Advisors, Inc. (the “Adviser”). Concurrently, the Adviser formed a wholly-owned subsidiary, Nuveen Asset Management, LLC (the “Sub-Adviser”), to house its portfolio management capabilities and to serve as the Funds’ sub-adviser, and the Funds’ portfolio managers became employees of the Sub-Adviser. This allocation of responsibilities between the Adviser and the Sub-Adviser affects each of the Funds. The Adviser will compensate the Sub-Adviser for the portfolio management services it provides to the Funds from each Fund’s management fee.

Each Fund seeks to provide current income exempt from regular federal income tax, and in the case of Insured Tax-Free Advantage (NEA) the alternative minimum tax applicable to individuals, by investing primarily in a portfolio of municipal obligations issued by state and local government authorities or certain U.S. territories.

Significant Accounting Policies

The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”).

Investment Valuation

Prices of municipal bonds are provided by a pricing service approved by the Funds’ Board of Directors/Trustees. These securities are generally classified as Level 2 for fair value measurement purposes. When price quotes are not readily available (which is usually the case for municipal bonds) the pricing service establishes a security’s fair value using methods that may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. In pricing certain securities, particularly less liquid and lower quality securities, the pricing service may consider information about a security, its issuer, or market activity, provided by the Adviser. These securities are generally classified as Level 2 or Level 3 depending on the priority of the significant inputs. Investments in investment companies are valued at their respective net asset values on the valuation date. These investment vehicles are generally classified as Level 1.

Certain securities may not be able to be priced by the pre-established pricing methods as described above. Such securities may be valued by the Funds’ Board of Directors/Trustees or its designee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; debt securities that have gone into default and for which there is no current market quotation; a security whose market price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund’s net asset value (as may be the case in non-U.S. markets on which the security is primarily traded) or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, is not deemed to reflect the security’s fair value. As a general principle, the fair value of a security would appear to be the amount that the owner might reasonably expect to receive for it in a current sale. A variety of factors may be considered in determining the fair value of such securities, which may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant.

102 |  | Nuveen Investments |  |

These securities are generally classified as Level 2 or Level 3 depending on the priority of the significant inputs. Regardless of the method employed to value a particular security, all valuations are subject to review by the Funds’ Board of Directors/Trustees or its designee.

Refer to Footnote 2 – Fair Value Measurements for further details on the leveling of securities held by the Funds as of the end of the reporting period.

Investment Transactions

Investment transactions are recorded on a trade date basis. Realized gains and losses from transactions are determined on the specific identification method, which is the same basis used for federal income tax purposes. Investments purchased on a when-issued/delayed delivery basis may have extended settlement periods. Any investments so purchased are subject to market fluctuation during this period. The Funds have instructed the custodian to segregate assets with a current value at least equal to the amount of the when-issued/delayed delivery purchase commitments. At October 31, 2011, Insured Quality (NQI), Insured Opportunity (NIO), Premier Insured Income (NIF), Insured Premium Income 2 (NPX), Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage (NEA) had outstanding when-issued/delayed delivery purchase commitments of $2,744,897, $1,848,150, $2,789,433, $7,542,365, $3,262,608 and $4,021,533, respectively.

Investment Income

Dividend income is recorded on the ex-dividend date. Investment income, which reflects the amortization of premiums and includes accretion of discounts for financial reporting purposes, is recorded on an accrual basis. Investment income also reflects paydown gains and losses, if any.

Professional Fees

Professional fees presented on the Statement of Operations consist of legal fees incurred in the normal course of operations, audit fees, tax consulting fees and, in some cases, workout expenditures. Workout expenditures are incurred in an attempt to protect or enhance an investment, or to pursue other claims or legal actions on behalf of Fund shareholders.

Income Taxes

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all of its net investment income and net capital gains to shareholders and to otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. Therefore, no federal income tax provision is required. Furthermore, each Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from regular federal income tax, and in the case of Insured Tax-Free Advantage (NEA) the alternative minimum tax applicable to individuals, to retain such tax-exempt status when distributed to shareholders of the Funds. Net realized capital gains and ordinary income distributions paid by the Funds are subject to federal taxation.

For all open tax years and all major taxing jurisdictions, management of the Funds has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. Open tax years are those that are open for examination by taxing authorities (i.e., generally the last four tax year ends and the interim tax period since then). Furthermore, management of the Funds is also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

Dividends and Distributions to Common Shareholders

Dividends from net investment income are declared monthly. Net realized capital gains and/or market discount from investment transactions, if any, are distributed to shareholders at least annually. Furthermore, capital gains are distributed only to the extent they exceed available capital loss carryforwards.

Distributions to Common shareholders of net investment income, net realized capital gains and/or market discount, if any, are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

Auction Rate Preferred Shares

Each Fund is authorized to issue Auction Rate Preferred Shares (“ARPS”). As of October 31, 2010, Insured Premium Income 2 (NPX) redeemed all of its outstanding ARPS at liquidation value. During the fiscal year ended October 31, 2011, Insured Quality (NQI), Insured Opportunity (NIO), Premier Insured Income (NIF), Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage (NEA) had issued and outstanding ARPS, $25,000 stated value per share, which approximates market value, as a means of effecting financial leverage. Each Fund’s ARPS were issued in one or more Series. The dividend rate paid by the Funds on each Series was determined every seven days, pursuant to a dutch auction process overseen by the auction agent, and was payable at the end of each rate period.

Beginning in February 2008, more shares for sale were submitted in the regularly scheduled auctions for the ARPS issued by the Funds than there were offers to buy. This meant that these auctions “failed to clear,” and that many Auction Rate Preferred shareholders who wanted to sell their shares in these auctions were unable to do so. Auction Rate Preferred shareholders unable to sell their shares received distributions at the “maximum rate”

applicable to failed auctions as calculated in accordance with the pre-established terms of the ARPS. As of October 31, 2011, each Fund redeemed all of their outstanding ARPS, at liquidation value, as follows:

During the fiscal year ended October 31, 2010, lawsuits pursuing claims made in a demand letter alleging that Insured Quality (NQI), Premier Insured Income (NIF), Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage’s (NEA) Board of Directors/Trustees breached their fiduciary duties related to the redemption at par of the Funds’ ARPS, had been filed on behalf of shareholders of the Funds, against the Adviser, the Nuveen holding company, the majority owner of the holding company, the lone interested director/trustee, and current and former officers of the Funds. Nuveen and other named defendants filed a motion to dismiss the lawsuits and on December 16, 2011, the court granted that motion dismissing the lawsuits with prejudice.

During the current reporting period, Nuveen Investments, LLC, known as Nuveen Securities, LLC, effective April 30, 2011, (“Nuveen Securities”) entered into a settlement with the Financial Industry Regulatory Authority (“FINRA”) with respect to certain allegations regarding Nuveen-sponsored closed-end fund ARPS marketing brochures. As part of this settlement, Nuveen Securities neither admitted to nor denied FINRA’s allegations. Nuveen Securities is the broker-dealer subsidiary of Nuveen.

The settlement with FINRA concludes an investigation that followed the widespread failure of auctions for ARPS and other auction rate securities, which generally began in mid-February 2008. In the settlement, FINRA alleged that certain marketing materials provided by Nuveen Securities were false and misleading. Nuveen Securities agreed to a censure and the payment of a $3 million fine.

MuniFund Term Preferred Shares

The following Funds have issued and outstanding MuniFund Term Preferred (“MTP”) Shares, with a $10.00 stated (“par”) value per share. Proceeds from the issuance of MTP Shares, net of offering expenses, were used to redeem all, or a portion of, each Fund’s outstanding ARPS. Each Fund’s MTP Shares are issued in one Series. Dividends on MTP Shares, which are recognized as interest expense for financial reporting purposes, are paid monthly at a fixed annual rate, subject to adjustments in certain circumstances. The MTP Shares trade on the NYSE. As of October 31, 2011, the number of MTP Shares outstanding, annual interest rate and the NYSE “ticker” symbol for each Fund’s series of MTP Shares are as follows:

|  | Insured Dividend Advantage (NVG) |  |  | Insured Tax-Free Advantage (NEA) |

Each Fund is obligated to redeem its MTP Shares by the date as specified in its offering document (“Term Redemption Date”), unless earlier redeemed or repurchased by the Fund. MTP Shares are subject to optional and mandatory redemption in certain circumstances. MTP Shares will be subject to redemption at the option of each Fund (“Optional Redemption Date”), subject to payment of a premium for one year following the Optional Redemption Date (“Premium Expiration Date”), and at par thereafter. The MTP Shares also will be subject to redemption, at the option of each Fund, at par in the event of certain changes in the credit rating of the MTP Shares. Each Fund may be obligated to redeem certain of the MTP Shares if the Fund fails to maintain certain asset coverage and leverage ratio requirements and such failures are not cured by the applicable cure date. The redemption price per share is equal to the sum of the liquidation value per share plus any accumulated but unpaid dividends. The Term Redemption Date, Optional Redemption Date and Premium Expiration Date for each Fund’s series of MTP Shares are as follows:

|  | Insured Dividend Advantage (NVG) Series 2014 |  |  | Insured Tax-Free Advantage (NEA) Series 2015 |

The average liquidation value for all series of MTP Shares outstanding for each Fund during the fiscal year ended October 31, 2011, was as follows:

|  | Insured Dividend Advantage (NVG) |  |  | Insured Tax-Free Advantage (NEA) |
Average liquidation value of MTP Shares outstanding |  | $ | 108,000,000 |  |  | $ | 83,000,000 |

For financial reporting purposes only, the liquidation value of MTP Shares is recorded as a liability on the Statement of Assets and Liabilities. Unpaid dividends on MTP Shares are recognized as a component of “Interest payable” on the Statement of Assets and Liabilities. Dividends paid on MTP Shares are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations.

Nuveen has agreed that net amounts earned by Nuveen as underwriter of each Fund’s MTP Share offering would be credited to the Funds, and would be recorded as reductions of offering costs recognized by the Funds. During the fiscal year ended October 31, 2011, Nuveen earned no net underwriting amounts on the Funds’ MTP Shares.

Variable Rate MuniFund Term Preferred Shares

The following Funds have issued and outstanding Variable Rate MuniFund Term Preferred (“VMTP”) Shares, with $100,000 liquidation value per share. Insured Quality (NQI), Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage (NEA) issued their VMTP Shares in a privately negotiated offering during February 2011, September 2011 and July 2011, respectively. Proceeds from the issuance of VMTP Shares, net of offering expenses, were used to redeem each Fund’s outstanding ARPS. The Fund’s VMTP Shares were offered to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933. As of October 31, 2011, the number of VMTP Shares outstanding, at liquidation value, for each Fund is as follows:

|  | Insured Quality (NQI) |  |  | Insured Dividend Advantage (NVG) |  |  | Insured Tax-Free Advantage (NEA) |
Series 2014 |  | $ | 240,400,000 |  |  | $ | 92,500,000 |  |  | $ | 67,600,000 |

Each Fund is obligated to redeem its VMTP Shares by the date as specified in its offering document (“Term Redemption Date”), unless earlier redeemed or repurchased by the Fund. VMTP Shares are subject to optional and mandatory redemption in certain circumstances . The VMTP Shares are subject to redemption at the option of each Fund (“Optional Redemption Date”), subject to payment of premium for one year following the Optional Redemption Date (“Premium Expiration Date”), and at par thereafter. Each Fund may be obligated to redeem certain of the VMTP Shares if the Fund fails to maintain certain asset coverage and leverage ratio requirements and such failures are not cured by the applicable cure date. The redemption price per share is equal to the sum of the liquidation value per share plus any accumulated but unpaid dividends. The Term Redemption Date, Optional Redemption Date and Premium Expiration Date for each Fund’s VMTP Shares are as follows:

Variable Rate Demand Preferred Shares

The following Funds have issued and outstanding Variable Rate Demand Preferred (“VRDP”) Shares, with a $100,000 liquidation value per share. Insured Opportunity (NIO), Premier Insured Income (NIF) and Insured Premium Income 2 (NPX) issued their VRDP Shares in a privately negotiated offering during December 2010, December 2010 and August 2008, respectively. Concurrent with renewing agreements with the liquidity provider for its VRDP Shares in June 2010, Insured Premium Income 2 (NPX) exchanged all its 2,190 Series 1 VRDP Shares for 2,190 Series 2 VRDP Shares. The principal difference in terms between Series 1 and Series 2 VRDP Shares is the requirement that the Fund redeem VRDP Shares owned by the liquidity provider if the VRDP Shares have been owned by the liquidity provider through six months of continuous, unsuccessful remarketing. Proceeds of each Fund’s offering were used to redeem all of each Fund’s outstanding ARPS. The VRDP Shares were offered to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933. As of October 31, 2011, the number of VRDP Shares outstanding and maturity date for each Fund are as follows:

|  | Insured Opportunity (NIO) |  |  | Premier Insured Income (NIF) |  |  | Insured Premium Income 2 (NPX) |
Series |  |  | 1 |  |  |  | 1 |  |  |  | 2 |
Shares outstanding |  |  | 6,672 |  |  |  | 1,309 |  |  |  | 2,190 |
Maturity |  |  | December 1, 2040 |  |  |  | December 1, 2040 |  |  |  | August 1, 2038 |

VRDP Shares include a liquidity feature that allows VRDP shareholders to have their shares purchased by a liquidity provider with whom each Fund has contracted in the event that purchase orders for VRDP Shares in a remarketing are not sufficient in number to be matched with the sale orders in that remarketing. Each Fund is required to redeem any VRDP Shares that are still owned by the liquidity provider after six months of continuous, unsuccessful remarketing.

Dividends on the VRDP Shares (which are treated as interest payments for financial reporting purposes) are set weekly at a rate established by a remarketing agent; therefore, the market value of the VRDP Shares is expected to approximate its liquidation value. If remarketings for VRDP Shares are continuously unsuccessful for six months, the maximum rate is designed to escalate according to a specified schedule in order to enhance the remarketing agent’s ability to successfully remarket the VRDP Shares.

Subject to certain conditions, VRDP Shares may be redeemed, in whole or in part, at any time at the option of each Fund. Each Fund may also redeem certain of the VRDP Shares if the Fund fails to maintain certain asset coverage requirements and such failures are not cured by the applicable cure date. The redemption price per share is equal to the sum of the liquidation value per share plus any accumulated but unpaid dividends.

The average liquidation value outstanding and annualized dividend rate of VRDP Shares for each Fund during the fiscal year ended October 31, 2011, were as follows:

|  | Insured Opportunity (NIO)* |  |  | Premier Insured Income (NIF)** |  |  | Insured Premium Income 2 (NPX) |
Average liquidation value outstanding |  |  | 667,200,000 |  |  |  | 130,900,000 |  |  |  | 219,000,000 |
Annualized dividend rate |  |  | 0.40% |  |  |  | 0.41% |  |  |  | 0.37% |

* | For the period December 30, 2010 (issuance date of shares) through October 31, 2011.

** | For the period December 16, 2010 (issuance date of shares) through October 31, 2011.

For financial reporting purposes only, the liquidation value of VRDP Shares is recognized as a liability on the Statement of Assets and Liabilities. Unpaid dividends on VRDP Shares are recognized as a component of “Interest payable” on the Statement of Assets and Liabilities. Dividends paid on the VRDP Shares are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations. In addition to interest expense, each Fund also pays a per annum liquidity fee to the liquidity provider as well as a remarketing fee, which are recognized as components of “Fees on VRDP Shares” on the Statement of Operations.

Insurance

Since 2007, the financial status of most major municipal bond insurers has deteriorated substantially, and some insurers have gone out of business, rendering worthless the insurance policies they had written. Under normal circumstances, each Fund invests at least 80% of its managed assets (as defined in Footnote 7 – Management Fees and Other Transactions with Affiliates) in municipal securities that are covered by insurance guaranteeing the timely payment of principal and interest. In addition, the municipal securities in which each Fund invests will be investment grade at the time of

106 |  | Nuveen Investments |  |

purchase (including (i) bonds insured by investment grade rated insurers or are rated investment grade; (ii) unrated bonds that are judged to be investment grade by the Adviser; and (iii) escrowed bonds). Ratings below BBB by one or more national rating agencies are considered to be below investment grade.

Each insured municipal security is covered by Original Issue Insurance, Secondary Market Insurance or Portfolio Insurance. Assuming that the insurer remains creditworthy, the insurance feature of a municipal security guarantees the full payment of principal and interest when due through the life of an insured obligation. Such insurance does not guarantee the market value of the insured obligation or the value of the Fund’s Common shares. Original Issue Insurance and Secondary Market Insurance remain in effect as long as the municipal securities covered thereby remain outstanding and the insurer remains in business, regardless of whether the Funds ultimately dispose of such municipal securities. Consequently, the market value of the municipal securities covered by Original Issue Insurance or Secondary Market Insurance may reflect value attributable to the insurance. Portfolio Insurance, in contrast, is effective only while the municipal securities are held by the Funds and is reflected as an expense over the term of the policy, when applicable. Accordingly, neither the prices used in determining the market value of the underlying municipal securities nor the Common share net asset value of the Funds include value, if any, attributable to the Portfolio Insurance. Each policy of the Portfolio Insurance does, however, give the Funds the right to obtain permanent insurance with respect to the municipal security covered by the Portfolio Insurance policy at the time of its sale.

Inverse Floating Rate Securities

Each Fund is authorized to invest in inverse floating rate securities. An inverse floating rate security is created by depositing a municipal bond, typically with a fixed interest rate, into a special purpose trust created by a broker-dealer. In turn, this trust (a) issues floating rate certificates, in face amounts equal to some fraction of the deposited bond’s par amount or market value, that typically pay short-term tax-exempt interest rates to third parties, and (b) issues to a long-term investor (such as one of the Funds) an inverse floating rate certificate (sometimes referred to as an “inverse floater”) that represents all remaining or residual interest in the trust. The income received by the inverse floater holder varies inversely with the short-term rate paid to the floating rate certificates’ holders, and in most circumstances the inverse floater holder bears substantially all of the underlying bond’s downside investment risk and also benefits disproportionately from any potential appreciation of the underlying bond’s value. The price of an inverse floating rate security will be more volatile than that of the underlying bond because the interest rate is dependent on not only the fixed coupon rate of the underlying bond but also on the short-term interest paid on the floating rate certificates, and because the inverse floating rate security essentially bears the risk of loss of the greater face value of the underlying bond.

A Fund may purchase an inverse floating rate security in a secondary market transaction without first owning the underlying bond (referred to as an “externally-deposited inverse floater”), or instead by first selling a fixed-rate bond to a broker-dealer for deposit into the special purpose trust and receiving in turn the residual interest in the trust (referred to as a “self-deposited inverse floater”). The inverse floater held by a Fund gives the Fund the right (a) to cause the holders of the floating rate certificates to tender their notes at par, and (b) to have the broker transfer the fixed-rate bond held by the trust to the Fund, thereby collapsing the trust. An investment in an externally-deposited inverse floater is identified in the Portfolio of Investments as “(IF) – Inverse floating rate investment.” An investment in a self-deposited inverse floater is accounted for as a financing transaction. In such instances, a fixed-rate bond deposited into a special purpose trust is identified in the Portfolio of Investments as “(UB) – Underlying bond of an inverse floating rate trust reflected as a financing transaction,” with the Fund accounting for the short-term floating rate certificates issued by the trust as “Floating rate obligations” on the Statement of Assets and Liabilities. In addition, the Fund reflects in “Investment Income” the entire earnings of the underlying bond and recognizes the related interest paid to the holders of the short-term floating rate certificates as a component of “Interest expense and amortization of offering costs” on the Statement of Operations.

During the fiscal year ended October 31, 2011, each Fund invested in externally-deposited inverse floaters and/or self-deposited inverse floaters.

Each Fund may also enter into shortfall and forbearance agreements (sometimes referred to as a “recourse trust” or “credit recovery swap”) (such agreements referred to herein as “Recourse Trusts”) with a broker-dealer by which a Fund agrees to reimburse the broker-dealer, in certain circumstances, for the difference between the liquidation value of the fixed-rate bond held by the trust and the liquidation value of the floating rate certificates issued by the trust plus any shortfalls in interest cash flows. Under these agreements, a Fund’s potential exposure to losses related to or on inverse floaters may increase beyond the value of a Fund’s inverse floater investments as a Fund may potentially be liable to fulfill all amounts owed to holders of the floating rate certificates. At period end, any such shortfall is recognized as “Unrealized depreciation on Recourse Trusts” on the Statement of Assets and Liabilities.

At October 31, 2011, each Fund’s maximum exposure to externally-deposited Recourse Trusts, was as follows:

|  | Insured Quality (NQI) |  |  | Insured Opportunity (NIO) |  |  | Premier Insured Income (NIF) |  |  | Insured Premium Income 2 (NPX) |  |  | Insured Dividend Advantage (NVG) |  |  | Insured Tax-Free Advantage (NEA)
Maximum exposure to Recourse Trusts |  | $ | 26,610,000 |  |  | $ | 40,430,000 |  |  | $ | 15,375,000 |  |  | $ | 14,845,000 |  |  | $ | 6,665,000 |  |  | $6,665,000

The average floating rate obligations outstanding and average annual interest rate and fees related to self-deposited inverse floaters during the fiscal year ended October 31, 2011, were as follows:

|  | Insured Quality (NQI) |  |  | Insured Opportunity (NIO) |  |  | Premier Insured Income (NIF) |  |  | Insured Premium Income 2 (NPX) |  |  | Insured Dividend Advantage (NVG) |  |  | Insured Tax-Free Advantage (NEA)
Average floating rate obligations outstanding |  | $ | 57,132,548 |  |  | $ | 120,149,511 |  |  | $ | 21,240,260 |  |  | $ | 57,980,000 |  |  | $ | 28,413,334 |  |  | $13,040,000
Average annual interest rate and fees |  |  | 0.59 | % |  |  | 0.61 | % |  |  | 0.57 | % |  |  | 0.53 | % |  |  | 0.65 | % |  | 0.68%

Derivative Financial Instruments

Each Fund is authorized to invest in certain derivative instruments, including foreign currency forwards, futures, options and swap contracts. Although the Funds are authorized to invest in such financial instruments, and may do so in the future, they did not make any such investments during the fiscal year ended October 31, 2011.

Market and Counterparty Credit Risk

In the normal course of business each Fund may invest in financial instruments and enter into financial transactions where risk of potential loss exists due to changes in the market (market risk) or failure of the other party to the transaction to perform (counterparty credit risk). The potential loss could exceed the value of the financial assets recorded on the financial statements. Financial assets, which potentially expose each Fund to counterparty credit risk, consist principally of cash due from counterparties on forward, option and swap transactions, when applicable. The extent of each Fund’s exposure to counterparty credit risk in respect to these financial assets approximates their carrying value as recorded on the Statement of Assets and Liabilities. Futures contracts, when applicable, expose a Fund to minimal counterparty credit risk as they are exchange traded and the exchange’s clearinghouse, which is counterparty to all exchange traded futures, guarantees the futures contracts against default.

Each Fund helps manage counterparty credit risk by entering into agreements only with counterparties the Adviser believes have the financial resources to honor their obligations and by having the Adviser monitor the financial stability of the counterparties. Additionally, counterparties may be required to pledge collateral daily (based on the daily valuation of the financial asset) on behalf of each Fund with a value approximately equal to the amount of any unrealized gain above a pre-determined threshold. Reciprocally, when each Fund has an unrealized loss, the Funds have instructed the custodian to pledge assets of the Funds as collateral with a value approximately equal to the amount of the unrealized loss above a pre-determined threshold. Collateral pledges are monitored and subsequently adjusted if and when the valuations fluctuate, either up or down, by at least the pre-determined threshold amount.

Zero Coupon Securities

Each Fund is authorized to invest in zero coupon securities. A zero coupon security does not pay a regular interest coupon to its holders during the life of the security. Tax-exempt income to the holder of the security comes from accretion of the difference between the original purchase price of the security at issuance and the par value of the security at maturity and is effectively paid at maturity. The market prices of zero coupon securities generally are more volatile than the market prices of securities that pay interest periodically.

Offering Costs

Costs incurred by Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage (NEA) in connection with their offerings of MTP Shares ($1,875,000 and $1,605,000, respectively) were recorded as deferred charges, which are being amortized over the life of the shares. Costs incurred by Insured Quality (NQI), Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage (NEA) in connection with their VMTP Shares ($1,120,000, $485,000 and $180,000, respectively) were recorded as deferred charges, which are being amortized over the life of the shares. Costs incurred by Insured Opportunity (NIO), Premier Insured Income (NIF) and Insured Premium Income 2 (NPX) in connection with their offerings of VRDP Shares ($2,645,000, $755,000 and $2,535,000, respectively) were recorded as deferred charges, which are being amortized over the life of the shares. Each Fund’s amortized deferred charges are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations.

Custodian Fee Credit

Each Fund has an arrangement with the custodian bank whereby certain custodian fees and expenses are reduced by net credits earned on each Fund’s cash on deposit with the bank. Such deposit arrangements are an alternative to overnight investments. Credits for cash balances may be offset by charges for any days on which a Fund overdraws its account at the custodian bank.

Indemnifications

Under the Funds’ organizational documents, their officers and directors/trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In addition, in the normal course of business, the Funds enter into contracts that provide general indemnifications to other parties. The Funds’ maximum exposure under these arrangements is unknown as this would involve future claims that may be

108 |  | Nuveen Investments |  |

made against the Funds that have not yet occurred. However, the Funds have not had prior claims or losses pursuant to these contracts and expect the risk of loss to be remote.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets applicable to Common shares from operations during the reporting period. Actual results may differ from those estimates.

2. Fair Value Measurements

Fair value is defined as the price that the Funds would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes.

Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad levels listed below:

Level 1 – Quoted prices in active markets for identical securities.

Level 2 – Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).

Level 3 – Significant unobservable inputs (including management’s assumptions in determining the fair value of investments).

The inputs or methodologies used for valuing securities are not an indication of the risk associated with investing in those securities. The following is a summary of each Fund’s fair value measurements as of October 31, 2011:

6. Income Tax Information

The following information is presented on an income tax basis. Differences between amounts for financial statement and federal income tax purposes are primarily due to timing differences in recognizing taxable market discount, timing differences in recognizing certain gains and losses on investment transactions and the treatment of investments in inverse floating rate securities reflected as financing transactions, if any. To the extent that differences arise that are permanent in nature, such amounts are reclassified within the capital accounts as detailed below. Temporary differences do not require reclassification. Temporary and permanent differences do not impact the net asset values of the Funds.

At October 31, 2011, the cost and unrealized appreciation (depreciation) of investments, as determined on a federal income tax basis, were as follows:

|  | Insured Quality (NQI) |  |  | Insured Opportunity (NIO) |  |  | Premier Insured Income (NIF) |  |  | Insured Premium Income 2 (NPX) |  |  | Insured Dividend Advantage (NVG) |  |  | Insured Tax-Free Advantage (NEA) |

7. Management Fees and Other Transactions with Affiliates

Each Fund’s management fee consists of two components – a fund-level fee, based only on the amount of assets within the Fund, and a complex-level fee, based on the aggregate amount of all eligible fund assets managed by the Adviser. This pricing structure enables Fund shareholders to benefit from growth in the assets within their respective Fund as well as from growth in the amount of complex-wide assets managed by the Adviser.

$250 billion |  |  | .1469 |
$300 billion |  |  | .1445 |

* | For the fund-level and complex-level fees, managed assets include closed-end fund assets managed by the Adviser that are attributable to financial leverage. For these purposes, financial leverage includes the funds’ use of preferred stock and borrowings and certain investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities, subject to an agreement by the Adviser as to certain funds to limit the amount of such assets for determining managed assets in certain circumstances. The complex-level fee is calculated based upon the aggregate daily managed assets of all Nuveen Funds that constitute “eligible assets.” Eligible assets do not include assets attributable to investments in other Nuveen Funds or assets in excess of $2 billion added to the Nuveen Fund complex in connection with the Adviser’s assumption of the management of the former First American Funds effective January 1, 2011. As of October 31, 2011, the complex-level fee rate for these Funds was .1759%.

The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. The Adviser is responsible for each Fund’s overall strategy and asset allocation decisions. The Adviser has entered into sub-advisory agreements with the Sub-Adviser under which the Sub-Adviser manages the investment portfolios of the Funds. The Sub-Adviser is compensated for its services to the Funds from the management fees paid to the Adviser.

The Funds pay no compensation directly to those of its directors/trustees who are affiliated with the Adviser or to its officers, all of whom receive remuneration for their services to the Funds from the Adviser or its affiliates. The Board of Directors/Trustees has adopted a deferred compensation plan for independent directors/trustees that enables directors/trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen-advised funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen-advised funds.

114 |  | Nuveen Investments |  |

For the first ten years of Insured Dividend Advantage’s (NVG) operations, the Adviser has agreed to reimburse the Fund, as a percentage of average daily managed assets, for fees and expenses in the amounts and for the time periods set forth below:

Year Ending March 31, |  |  |  | Year Ending March 31, |  |
2002* |  | .30% |  | 2008 |  | .25%

The Adviser has not agreed to reimburse Insured Dividend Advantage (NVG) for any portion of its fees and expenses beyond March 31, 2012.

For the first eight years of Insured Tax-Free Advantage’s (NEA) operations, the Adviser has agreed to reimburse the Fund, as a percentage of average daily managed assets, for fees and expenses in the amounts and for the time periods set forth below:

The Adviser has not agreed to reimburse Insured Tax-Free Advantage (NEA) for any portion of its fees and expenses beyond November 30, 2010.

8. New Accounting Pronouncements

Fair Value Measurements and Disclosures

On May 12, 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-04 (“ASU No. 2011-04”) modifying Topic 820, Fair Value Measurements and Disclosures. At the same time, the International Accounting Standards Board (“IASB”) issued International Financial Reporting Standard (“IFRS”) 13, Fair Value Measurement. The objective of the FASB and IASB is convergence of their guidance on fair value measurements and disclosures. Specifically, ASU No. 2011-04 requires reporting entities to disclose i) the amounts of any transfers between Level 1 and Level 2 and the reasons for the transfers and ii) for Level 3 fair value measurements, a) quantitative information about significant unobservable inputs used, b) a description of the valuation processes used by the reporting entity and c) a narrative description of the sensitivity of the fair value measurement to changes in unobservable inputs if a change in those inputs might result in a significantly higher or lower fair value measurement. The effective date of ASU No. 2011-04 is for interim and annual periods beginning after December 15, 2011. At this time, management is evaluating the implications of this guidance and the impact it will have on the financial statement amounts and footnote disclosures, if any.

9. Subsequent Events

On October 28, 2011, the Fund’s Board of Directors/Trustees approved changes to each Fund’s investment policy regarding investment in insured municipal securities. These changes are designed to provide the Adviser with more flexibility regarding the types of securities available for investment by each Fund.

Effective January 2, 2012, each Fund will eliminate the investment policy requiring it, under normal circumstances, to invest at least 80% of its Managed Assets in municipal securities that are covered by insurance guaranteeing the timely payment of principal and interest. Since 2007, most municipal bond insurers have had their credit ratings downgraded and only one insurer is currently insuring new municipal bonds. As a result, the supply of insured municipal securities has decreased dramatically and the long-term viability of the municipal bond insurance market is uncertain. The Funds are not changing their investment objective and will continue to invest substantially all of their assets in a portfolio of investment grade quality municipal securities.

Concurrent with the investment policy changes, the Funds will change their names as follows:

• Insured Quality (NQI) will change to Nuveen Quality Municipal Fund, Inc. (NQI)

• Insured Opportunity (NIO) will change to Nuveen Municipal Opportunity Fund, Inc. (NIO)

• Premier Insured Income (NIF) will change to Nuveen Premier Municipal Opportunity Fund, Inc. (NIF)

• Insured Premium Income 2 (NPX) will change to Nuveen Premium Income Municipal Opportunity Fund. (NPX)

• Insured Dividend Advantage (NVG) will change to Nuveen Dividend Advantage Municipal Income Fund. (NVG)

• Insured Tax-Free Advantage (NEA) will change to Nuveen AMT-Free Municipal Income Fund. (NEA)

Annual Investment Management Agreement

Approval Process (Unaudited)

The Board of Trustees or Directors (as the case may be) (each, a “Board” and each Trustee or Director, a “Board Member”) of the Funds, including the Board Members who are not parties to the Funds’ advisory or sub-advisory agreements or “interested persons” of any such parties (the “Independent Board Members”), is responsible for approving the advisory agreements (each, an “Investment Management Agreement”) between each Fund and Nuveen Fund Advisors, Inc. (the “Advisor”) and the sub-advisory agreements (each a “Sub-Advisory Agreement”) between the Advisor and Nuveen Asset Management, LLC (the “Sub-Advisor”) (the Investment Management Agreements and the Sub-Advisory Agreements are referred to collectively as the “Advisory Agreements”) and their periodic continuation. Pursuant to the Investment Company Act of 1940, as amended (the “1940 Act”), the Board is generally required to consider the continuation of advisory agreements and sub-advisory agreements on an annual basis. Accordingly, at an in-person meeting held on May 23-25, 2011 (the “May Meeting”), the Board, including a majority of the Independent Board Members, considered and approved the continuation of the Advisory Agreements for the Funds for an additional one-year period.

In preparation for their considerations at the May Meeting, the Board requested and received extensive materials prepared in connection with the review of the Advisory Agreements. The materials provided a broad range of information regarding the Funds, the Advisor and the Sub-Advisor (the Advisor and the Sub-Advisor are collectively, the “Fund Advisers” and each, a “Fund Adviser”). As described in more detail below, the information provided included, among other things, a review of Fund performance, including Fund investment performance assessments against peer groups and appropriate benchmarks, a comparison of Fund fees and expenses relative to peers, a description and assessment of shareholder service levels for the Funds, a summary of the performance of certain service providers, a review of product initiatives and shareholder communications and an analysis of the Advisor’s profitability with comparisons to comparable peers in the managed fund business. As part of their annual review, the Board also held a separate meeting on April 19-20, 2011, to review the Funds’ investment performance and consider an analysis provided by the Advisor of the Sub-Advisor which generally evaluated the Sub-Advisor’s investment team, investment mandate, organizational structure and history, investment philosophy and process, performance of the applicable Fund, and significant changes to the foregoing. As a result of their review of the materials and discussions, the Board presented the Advisor with questions and the Advisor responded.

116 |  | Nuveen Investments |  |

The materials and information prepared in connection with the review of the Advisory Agreements at the May Meeting supplemented the information provided to the Board during the year. In this regard, throughout the year, the Board, acting directly or through its committees, regularly reviews the performance and various services provided by the Advisor and, since the internal restructuring described in Section A below, the Sub-Advisor. The Board meets at least quarterly as well as at other times as the need arises. At its quarterly meetings, the Board reviews reports by the Advisor which include, among other things, Fund performance, a review of the investment teams and compliance reports. The Board also meets with key investment personnel managing the Fund portfolios during the year. In addition, the Board continues its program of seeking to visit each sub-advisor to the Nuveen funds at least once over a multiple year rotation, meeting with key investment and business personnel. The Board also met with State Street Bank & Trust Company, the Funds’ accountant and custodian, in 2010. The Board considers factors and information that are relevant to its consideration of the renewal of the Advisory Agreements at these meetings held throughout the year. Accordingly, the Board considered the information provided and knowledge gained at these meetings when performing its review at the May Meeting of the Advisory Agreements. The Independent Board Members are assisted throughout the process by independent legal counsel who provided materials describing applicable law and the duties of directors or trustees in reviewing advisory contracts and met with the Independent Board Members in executive sessions without management present.

The Board considered all factors it believed relevant with respect to each Fund, including among other factors: (a) the nature, extent and quality of the services provided by the Fund Advisers, (b) the investment performance of the Fund and Fund Advisers, (c) the advisory fees and costs of the services to be provided to the Funds and the profitability of the Fund Advisers, (d) the extent of any economies of scale, (e) any benefits derived by the Fund Advisers from the relationship with the Fund and (f) other factors. Each Board Member may have accorded different weight to the various factors in reaching his or her conclusions with respect to a Fund’s Advisory Agreements. The Independent Board Members did not identify any single factor as all important or controlling. The Independent Board Members’ considerations were instead based on a comprehensive consideration of all the information presented. The principal factors considered by the Board and its conclusions are described below.

A. Nature, Extent and Quality of Services

In considering renewal of the Advisory Agreements, the Independent Board Members considered the nature, extent and quality of the Fund Adviser’s services, including advisory services and the resulting Fund performance and administrative services. The Independent Board Members reviewed materials outlining, among other things, the Fund Adviser’s organization and business; the types of services that the Fund Adviser or its affiliates provide to the Funds; the performance record of the applicable Fund (as described in further detail below); and any initiatives Nuveen had taken for the applicable fund product line.

|  | Nuveen Investments |  | 117

Annual Investment Management Agreement

Approval Process (Unaudited) (continued)

In considering advisory services, the Board recognized that the Advisor provides various oversight, administrative, compliance and other services for the Funds and the Sub-Advisor provides the portfolio investment management services to the Funds. The Board recognized that Nuveen engaged in an internal restructuring in 2010 pursuant to which portfolio management services the Advisor had provided directly to the Funds were transferred to the Sub-Advisor, a newly-organized, wholly-owned subsidiary of the Advisor consisting of largely the same investment personnel. Accordingly, in reviewing the portfolio management services provided to each Fund, the Board reviewed the materials provided by the Nuveen Investment Services Oversight Team analyzing, among other things, the Sub-Advisor’s investment team and changes thereto, organization and history, assets under management, Fund objectives and mandate, the investment team’s philosophy and strategies in managing the Fund, developments affecting the Sub-Advisor or Fund and Fund performance. The Independent Board Members also reviewed portfolio manager compensation arrangements to evaluate each Fund Adviser’s ability to attract and retain high quality investment personnel, preserve stability, and reward performance but not provide an incentive to take undue risks. In addition, the Board considered the Advisor’s execution of its oversight responsibilities over the Sub-Advisor. Given the importance of compliance, the Independent Board Members also considered Nuveen’s compliance program, including the report of the chief compliance officer regarding the Funds’ compliance policies and procedures.

In addition to advisory services, the Board considered the quality and extent of administrative and other non-investment advisory services the Advisor and its affiliates provide to the Funds, including product management, investment services (such as oversight of investment policies and procedures, risk management, and pricing), fund administration, oversight of service providers, shareholder services, administration of Board relations, regulatory and portfolio compliance, legal support, managing leverage and promoting an orderly secondary market for common shares.

In reviewing the services provided, the Board also reviewed materials describing various notable initiatives and projects the Advisor performed in connection with the closed-end fund product line. These initiatives included continued activities to refinance auction rate preferred securities; ongoing services to manage leverage that has become increasingly complex; continued secondary market offerings and share repurchases for certain funds; and continued communications efforts with shareholders, fund analysts and financial advisers. With respect to the latter, the Independent Board Members noted Nuveen’s continued commitment to supporting the secondary market for the common shares of its closed-end funds through a comprehensive secondary market communication program designed to raise investor and analyst awareness and understanding of closed-end funds. Nuveen’s support services included, among other things: continuing communications in support of refinancing efforts related to auction rate preferred securities; participating in conferences; communicating continually with closed-end fund analysts covering the Nuveen funds;

118 |  | Nuveen Investments |  |

providing marketing for the closed-end funds; share purchases; and maintaining and enhancing a closed-end fund website.

Based on their review, the Independent Board Members found that, overall, the nature, extent and quality of services provided to the respective Funds under each applicable Advisory Agreement were satisfactory.

B. The Investment Performance of the Funds and Fund Advisers

The Board, including the Independent Board Members, reviewed and considered the performance history of each Fund over various time periods. The Board reviewed, among other things, each Fund’s historic investment performance as well as information comparing the Fund’s performance information with that of other funds (the “Performance Peer Group”) based on data provided by an independent provider of mutual fund data and with recognized and/or customized benchmarks.

The Board reviewed reports, including a comprehensive analysis of the Funds’ performance and the applicable investment team. In this regard, the Board reviewed each Fund’s total return information compared to its Performance Peer Group for the quarter, one-, three- and five-year periods ending December 31, 2010 and for the same periods ending March 31, 2011. In addition, the Board reviewed each Fund’s total return information compared to recognized and/or customized benchmarks for the quarter, one- and three-year periods ending December 31, 2010 and for the same periods ending March 31, 2011. The Independent Board Members also reviewed historic premium and discount levels, including a summary of actions taken to address or discuss other developments affecting the secondary market discounts of various funds. This information supplemented the Fund performance information provided to the Board at each of its quarterly meetings.

In reviewing performance comparison information, the Independent Board Members recognized that the usefulness of the comparisons of the performance of certain funds with the performance of their respective Performance Peer Group may be limited because the Performance Peer Group may not adequately represent the objectives and strategies of the applicable funds or may be limited in size or number. The Independent Board Members also noted that the investment experience of a particular shareholder in the Nuveen funds will vary depending on when such shareholder invests in the applicable fund, the class held (if multiple classes are offered) and the performance of the fund (or respective class) during that shareholder’s investment period.

In considering the results of the comparisons, the Independent Board Members observed, among other things, that (a) the Nuveen Insured Tax-Free Advantage Municipal Fund (the “Insured Tax-Free Advantage Fund”), the Nuveen Insured Dividend Advantage Municipal Fund (the “Insured Dividend Advantage Fund”) and the Nuveen Premier Insured Municipal Income Fund, Inc. (the “Premier Insured Fund”) had demonstrated generally favorable performance in comparison to peers, performing in the first or second quartile over various periods and (b) the Nuveen Insured Premium Income

|  | Nuveen Investments |  | 119

Annual Investment Management Agreement

Approval Process (Unaudited) (continued)

Municipal Fund 2 (the “Insured Premium Income Fund 2”) had demonstrated satisfactory performance compared to peers, performing in the third quartile over various periods. They also noted that the Nuveen Insured Municipal Opportunity Fund, Inc. (the “Insured Municipal Opportunity Fund”) and the Nuveen Insured Quality Municipal Fund, Inc. (the “Insured Quality Fund”) lagged their peers and/or benchmarks over various periods. With respect to Nuveen funds that lagged their peers and/or benchmarks over various periods, the Independent Board Members considered the factors affecting performance and any steps taken or proposed to address performance issues, and were satisfied with the process followed.

With respect to any Nuveen funds that underperformed their peers and/or benchmarks from time to time, the Board monitors such funds closely and considers any steps necessary or appropriate to address such issues.

Except as otherwise noted above, based on their review, the Independent Board Members determined that each Fund’s investment performance had been satisfactory.

C. Fees, Expenses and Profitability

1. Fees and Expenses

The Board evaluated the management fees and expenses of each Fund reviewing, among other things, such Fund’s gross management fees, net management fees and net expense ratios in absolute terms as well as compared to the fee and expenses of a comparable universe of funds based on data provided by an independent fund data provider (the “Peer Universe”) and in certain cases, to a more focused subset of funds in the Peer Universe (the “Peer Group”) and any expense limitations.

The Independent Board Members further reviewed the methodology regarding the construction of the applicable Peer Universe and Peer Group (if any). In reviewing the comparisons of fee and expense information, the Independent Board Members took into account that in certain instances various factors such as: the asset level of a fund relative to peers; the limited size and particular composition of the Peer Universe or Peer Group; the investment objectives of the peers; expense anomalies; changes in the funds comprising the Peer Universe or Peer Group from year to year; levels of reimbursement; the timing of information used; and the differences in the type and use of leverage may impact the comparative data thereby limiting the ability to make a meaningful comparison with peers, including for the Insured Dividend Advantage Fund and the Insured Tax-Free Advantage Fund.

In reviewing the fee schedule for a Fund, the Independent Board Members also considered the fund-level and complex-wide breakpoint schedules (described in further detail below) and any fee waivers and reimbursements provided by Nuveen (applicable, in particular, for certain closed-end funds launched since 1999). In reviewing fees and expenses, the Board considered the expenses and fees to be higher if they were over 10 basis points higher, slightly higher if they were 6 to 10 basis points higher, in line if they were within 5 basis points higher than the peer average and below if they were below the peer average of the Peer Group (if available) or Peer Universe if there was no separate Peer Group.

120 |  | Nuveen Investments |  |

The Independent Board Members noted that the Insured Quality Fund and the Premier Insured Fund had higher net management fees than their peer averages and a slightly higher or higher net expense ratio compared to their peer averages while the Insured Municipal Opportunity Fund and the Insured Premium Income Fund 2 had net management fees higher than their peer averages but a net expense ratio in line with their peer averages. In addition, the Independent Board Members observed that each of the other Funds had net management fees and net expense ratios below their peer averages.

Based on their review of the fee and expense information provided, the Independent Board Members determined that each Fund’s management fees were reasonable in light of the nature, extent and quality of services provided to the Fund.

2. Comparisons with the Fees of Other Clients

The Independent Board Members further reviewed information regarding the nature of services and fee rates offered by the Advisor to other clients, including municipal separately managed accounts and passively managed exchange traded funds (ETFs) sub-advised by the Advisor. In evaluating the comparisons of fees, the Independent Board Members noted that the fee rates charged to the Funds and other clients vary, among other things, because of the different services involved and the additional regulatory and compliance requirements associated with registered investment companies, such as the Funds. Accordingly, the Independent Board Members considered the differences in the product types, including, but not limited to, the services provided, the structure and operations, product distribution and costs thereof, portfolio investment policies, investor profiles, account sizes and regulatory requirements. The Independent Board Members noted, in particular, that the range of services provided to the Funds (as discussed above) is much more extensive than that provided to separately managed accounts. Given the inherent differences in the products, particularly the extensive services provided to the Funds, the Independent Board Members believe such facts justify the different levels of fees.

In considering the fees of the Sub-Advisor, the Independent Board Members also considered the pricing schedule or fees that the Sub-Advisor charges for similar investment management services for other Nuveen funds.

3. Profitability of Fund Advisers

In conjunction with its review of fees, the Independent Board Members also considered the profitability of Nuveen for its advisory activities (which incorporated Nuveen’s wholly-owned affiliated sub-advisers) and its financial condition. The Independent Board Members reviewed the revenues and expenses of Nuveen’s advisory activities for the last two years, the allocation methodology used in preparing the profitability data and an analysis of the key drivers behind the changes in revenues and expenses that impacted profitability in 2010. The Independent Board Members noted this information supplemented the profitability information requested and received during the year to help keep them apprised of developments affecting profitability (such as changes in fee waivers and expense reimbursement commitments). In this regard, the Independent Board Members noted that they have an Independent Board Member serve as a point person to

|  | Nuveen Investments |  | 121

Annual Investment Management Agreement

Approval Process (Unaudited) (continued)

review and keep them apprised of changes to the profitability analysis and/or methodologies during the year. The Independent Board Members also considered Nuveen’s revenues for advisory activities, expenses, and profit margin compared to that of various unaffiliated management firms with similar amounts of assets under management and relatively comparable asset composition prepared by Nuveen.

In reviewing profitability, the Independent Board Members recognized the subjective nature of determining profitability which may be affected by numerous factors including the allocation of expenses. Further, the Independent Board Members recognized the difficulties in making comparisons as the profitability of other advisers generally is not publicly available and the profitability information that is available for certain advisers or management firms may not be representative of the industry and may be affected by, among other things, the adviser’s particular business mix, capital costs, types of funds managed and expense allocations. Notwithstanding the foregoing, the Independent Board Members reviewed Nuveen’s methodology and assumptions for allocating expenses across product lines to determine profitability. In reviewing profitability, the Independent Board Members recognized Nuveen’s investment in its fund business. Based on their review, the Independent Board Members concluded that the Advisor’s level of profitability for its advisory activities was reasonable in light of the services provided.

In evaluating the reasonableness of the compensation, the Independent Board Members also considered other amounts paid to a Fund Adviser by the Funds as well as any indirect benefits (such as soft dollar arrangements, if any) the Fund Adviser and its affiliates receive, or are expected to receive, that are directly attributable to the management of the Funds, if any. See Section E below for additional information on indirect benefits a Fund Adviser may receive as a result of its relationship with the Funds. Based on their review of the overall fee arrangements of each Fund, the Independent Board Members determined that the advisory fees and expenses of the respective Fund were reasonable.

D. Economies of Scale and Whether Fee Levels Reflect These Economies of Scale

With respect to economies of scale, the Independent Board Members have recognized the potential benefits resulting from the costs of a fund being spread over a larger asset base, although economies of scale are difficult to measure and predict with precision, particularly on a fund-by-fund basis. One method to help ensure the shareholders share in these benefits is to include breakpoints in the advisory fee schedule. Generally, management fees for funds in the Nuveen complex are comprised of a fund-level component and a complex-level component, subject to certain exceptions. Accordingly, the Independent Board Members reviewed and considered the applicable fund-level breakpoints in the advisory fee schedules that reduce advisory fees as asset levels increase. Further, the Independent Board Members noted that although closed-end funds may from time-to-time make additional share offerings, the growth of their assets will occur primarily through the appreciation of such funds’ investment portfolio.

122 |  | Nuveen Investments |  |

In addition to fund-level advisory fee breakpoints, the Board also considered the Funds’ complex-wide fee arrangement. Pursuant to the complex-wide fee arrangement, the fees of the funds in the Nuveen complex are generally reduced as the assets in the fund complex reach certain levels. The complex-wide fee arrangement seeks to provide the benefits of economies of scale to fund shareholders when total fund complex assets increase, even if assets of a particular fund are unchanged or have decreased. The approach reflects the notion that some of Nuveen’s costs are attributable to services provided to all its funds in the complex and therefore all funds benefit if these costs are spread over a larger asset base.

Based on their review, the Independent Board Members concluded that the breakpoint schedules and complex-wide fee arrangement were acceptable and reflect economies of scale to be shared with shareholders when assets under management increase.

E. Indirect Benefits

In evaluating fees, the Independent Board Members received and considered information regarding potential “fall out” or ancillary benefits the respective Fund Adviser or its affiliates may receive as a result of its relationship with each Fund. In this regard, the Independent Board Members considered any revenues received by affiliates of the Advisor for serving as agent at Nuveen’s trading desk and as co-manager in initial public offerings of new closed-end funds.

In addition to the above, the Independent Board Members considered whether the Fund Advisers received any benefits from soft dollar arrangements whereby a portion of the commissions paid by a Fund for brokerage may be used to acquire research that may be useful to the Fund Adviser in managing the assets of the Funds and other clients. The Independent Board Members recognized that each Fund Adviser has the authority to pay a higher commission in return for brokerage and research services if it determines in good faith that the commission paid is reasonable in relation to the value of the brokerage and research services provided. Nevertheless, the Independent Board Members noted that commissions are generally not paid in connection with municipal securities transactions typically executed on a principal basis.

Based on their review, the Independent Board Members concluded that any indirect benefits received by a Fund Adviser as a result of its relationship with the Funds were reasonable and within acceptable parameters.

F. Other Considerations

The Independent Board Members did not identify any single factor discussed previously as all-important or controlling. The Board Members, including the Independent Board Members, unanimously concluded that the terms of each Advisory Agreement are fair and reasonable, that the respective Fund Adviser’s fees are reasonable in light of the services provided to each Fund and that the Advisory Agreements be renewed.

Reinvest Automatically,

Easily and Conveniently

Nuveen makes reinvesting easy. A phone call is all it takes to set up your reinvestment account.

Nuveen Closed-End Funds Automatic Reinvestment Plan

Your Nuveen Closed-End Fund allows you to conveniently reinvest distributions in additional Fund shares.

By choosing to reinvest, you’ll be able to invest money regularly and automatically, and watch your investment grow through the power of compounding. Just like distributions in cash, there may be times when income or capital gains taxes may be payable on distributions that are reinvested.

It is important to note that an automatic reinvestment plan does not ensure a profit, nor does it protect you against loss in a declining market.

Easy and convenient

To make recordkeeping easy and convenient, each month you’ll receive a statement showing your total distributions, the date of investment, the shares acquired and the price per share, and the total number of shares you own.

How shares are purchased

The shares you acquire by reinvesting will either be purchased on the open market or newly issued by the Fund. If the shares are trading at or above net asset value at the time of valuation, the Fund will issue new shares at the greater of the net asset value or 95% of the then-current market price. If the shares are trading at less than net asset value, shares for your account will be purchased on the open market. If the Plan Agent begins purchasing Fund shares on the open market while shares are trading below net asset value, but the Fund’s shares subsequently trade at or above their net asset value before the Plan Agent is able to complete its purchases, the Plan Agent may cease open-market purchases and may invest the uninvested portion of the distribution in newly-issued Fund shares at a price equal to the greater of the shares’ net asset value or 95% of the shares’ market value on the last business day immediately prior to the purchase date. Distributions received to purchase shares in the open market will normally be invested shortly after the distribution payment date. No interest will be paid on distributions awaiting reinvestment. Because the market price of the shares may increase before purchases are completed, the average purchase price per share may

|  | Nuveen Investments |  | 129

Reinvest Automatically

Easily and Conveniently (continued)

exceed the market price at the time of valuation, resulting in the acquisition of fewer shares than if the distribution had been paid in shares issued by the Fund. A pro rata portion of any applicable brokerage commissions on open market purchases will be paid by Plan participants. These commissions usually will be lower than those charged on individual transactions.

Flexible

You may change your distribution option or withdraw from the Plan at any time, should your needs or situation change.

You can reinvest whether your shares are registered in your name, or in the name of a brokerage firm, bank, or other nominee. Ask your investment advisor if his or her firm will participate on your behalf. Participants whose shares are registered in the name of one firm may not be able to transfer the shares to another firm and continue to participate in the Plan.

The Fund reserves the right to amend or terminate the Plan at any time. Although the Fund reserves the right to amend the Plan to include a service charge payable by the participants, there is no direct service charge to participants in the Plan at this time.

Call today to start reinvesting distributions

Glossary of Terms

Used in this Report

n |  | Auction Rate Bond: An auction rate bond is a security whose interest payments are adjusted periodically through an auction process, which process typically also serves as a means for buying and selling the bond. Auctions that fail to attract enough buyers for all the shares offered for sale are deemed to have “failed,” with current holders receiving a formula-based interest rate until the next scheduled auction.

n |  | Average Annual Total Return: This is a commonly used method to express an investment’s performance over a particular, usually multi-year time period. It expresses the return that would have been necessary each year to equal the investment’s actual cumulative performance (including change in NAV or market price and reinvested dividends and capital gains distributions, if any) over the time period being considered.

n |  | Average Effective Maturity: The market-value-weighted average of the effective maturity dates of the individual securities including cash. In the case of a bond that has been advance-refunded to a call date, the effective maturity is the date on which the bond is scheduled to be redeemed using the proceeds of an escrow account. In most other cases the effective maturity is the stated maturity date of the security.

n |  | Effective Leverage: Effective leverage is a Fund’s effective economic leverage, and includes both structural leverage and the leverage effects of certain derivative investments in the Fund’s portfolio. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values, in addition to any structural leverage.

n |  | Inverse Floaters: Inverse floating rate securities, also known as inverse floaters, are created by depositing a municipal bond, typically with a fixed interest rate, into a special purpose trust created by a broker-dealer. This trust, in turn, (a) issues floating rate certificates typically paying short-term tax-exempt interest rates to third parties in amounts equal to some fraction of the deposited bond’s par amount or market value, and (b) issues an inverse floating rate certificate (sometimes referred to as an “inverse floater”) to an investor (such as a Fund) interested in gaining investment exposure to a long-term municipal bond. The income received by the holder of the inverse floater varies inversely with the short-term rate paid to the floating rate certificates’ holders, and in most circumstances the holder of the inverse floater bears substantially all of the underlying bond’s downside investment risk. The holder of the inverse floater typically also benefits disproportionately from any potential appreciation of the underlying bond’s value. Hence, an inverse floater essentially represents an investment in the underlying bond on a leveraged basis.

n |  | Leverage: Using borrowed money to invest in securities or other assets.

|  | Nuveen Investments |  | 131

Glossary of Terms

Used in this Report (continued)

n |  | Leverage-Adjusted Duration: Duration is a measure of the expected period over which a bond’s principal and interest will be paid, and consequently is a measure of the sensitivity of a bond’s or bond Fund’s value to changes when market interest rates change. Generally, the longer a bond’s or Fund’s duration, the more the price of the bond or Fund will change as interest rates change. Leverage-adjusted duration takes into account the leveraging process for a Fund and therefore is longer than the duration of the Fund’s portfolio of bonds.

n |  | Lipper General and Insured Leveraged Municipal Debt Funds Classification Average: Calculated using the returns of all closed-end funds in this category for each period as follows: 1-year, 23 funds; 5-year, 22 funds; and 10-year, 13 funds. Lipper returns account for the effects of management fees and assume reinvestment of dividends, but do not reflect any applicable sales charges. The Lipper average is not available for direct investment.

n |  | Market Yield (also known as Dividend Yield or Current Yield): An investment’s current annualized dividend divided by its current market price.

n |  | Net Asset Value (NAV): The net market value of all securities held in a portfolio.

n |  | Net Asset Value (NAV) Per Share: The market value of one share of a mutual fund or closed-end fund. For a Fund, the NAV is calculated daily by taking the Fund’s total assets (securities, cash, and accrued earnings), subtracting the Fund’s liabilities, and dividing by the number of shares outstanding.

n |  | Pre-Refunding: Pre-Refunding, also known as advanced refundings or refinancings, is a procedure used by state and local governments to refinance municipal bonds to lower interest expenses. The issuer sells new bonds with a lower yield and uses the proceeds to buy U.S. Treasury securities, the interest from which is used to make payments on the higher-yielding bonds. Because of this collateral, pre-refunding generally raises a bond’s credit rating and thus its value.

n |  | Standard & Poor’s (S&P) National Insured Municipal Bond Index: An unleveraged, market value-weighted index designed to measure the performance of the tax-exempt, insured U.S. municipal bond market. The index returns assume reinvestment of dividends but do not reflect any applicable sales charges. You cannot invest directly in an index.

n |  | Structural Leverage: Structural Leverage consists of preferred shares or debt issued by the Fund. Both of these are part of a Fund’s capital structure. Structural leverage is sometimes referred to as “’40 Act Leverage” and is subject to asset coverage limits set in the Investment Company Act of 1940.

n |  | Taxable-Equivalent Yield: The yield necessary from a fully taxable investment to equal, on an after-tax basis, the yield of a municipal bond investment.

n |  | Zero Coupon Bond: A zero coupon bond does not pay a regular interest coupon to its holders during the life of the bond. Tax-exempt income to the holder of the bond comes from accretion of the difference between the original purchase price of the bond at issuance and the par value of the bond at maturity and is effectively paid at maturity. The market prices of zero coupon bonds generally are more volatile than the market prices of bonds that pay interest periodically.

Chairman’s

Letter to Shareholders

Dear Shareholders,

Investors have many reasons to remain cautious. The challenges in the Euro area are casting a shadow over global economies and financial markets. The political support for addressing fiscal issues is eroding as the economic and social impacts become more visible. At the same time, member nations appear unwilling to provide adequate financial support or to surrender sufficient sovereignty to strengthen the banks or unify the Euro area financial system. The gains made in reducing deficits, and the hard-won progress on winning popular acceptance of the need for economic austerity, are at risk. To their credit, European political leaders press on to find compromise solutions, but there is increasing concern that time will begin to run out.

In the U.S., strong corporate earnings have enabled the equity markets to withstand much of the downward pressures coming from weakening job creation, slower economic growth and political uncertainty. The Fed remains committed to low interest rates but has refrained from predicting another program of quantitative easing unless economic growth were to weaken significantly or the threat of recession appears on the horizon. Pre-election maneuvering has added to the already highly partisan atmosphere in the Congress. The end of the Bush-era tax cuts and implementation of the spending restrictions of the Budget Control Act of 2011, both scheduled to take place at year-end, loom closer.

During the last year, U.S. based investors have experienced a sharp decline and a strong recovery in the equity markets. The experienced investment teams at Nuveen keep their eye on a longer time horizon and use their practiced investment disciplines to negotiate through market peaks and valleys to achieve long-term goals for investors. Experienced professionals pursue investments that will weather short-term volatility and at the same time, seek opportunities that are created by markets that overreact to negative developments. Monitoring this process is an important consideration for the Fund Board as it oversees your Nuveen funds on your behalf.

As always, I encourage you to contact your financial consultant if you have any questions about your investment in a Nuveen Fund. On behalf of the other members of your Fund Board, we look forward to continuing to earn your trust in the months and years ahead.

Sincerely,

Robert P. Bremner

Chairman of the Board

Nuveen Premium Income Municipal Opportunity Fund (NPX)

Nuveen Dividend Advantage Municipal Income Fund (NVG)

Nuveen AMT-Free Municipal Income Fund (NEA)

Portfolio managers Paul Brennan and Douglas White discuss key investment strategies and the six-month performance of these six national Funds. With 21 years of industry experience, including 15 years at Nuveen, Paul has managed NIO, NIF, NVG, and NEA since 2006. Douglas, who has 29 years of financial industry experience, assumed portfolio management responsibility for NQI and NPX in January 2011.

What key strategies were used to manage these Funds during the six-month reporting period ended April 30, 2012?

During this period, municipal bond prices generally rallied, amid strong demand and yield that continued to be historically low. The availability of municipal supply improved in recent months from 2011 levels, although the pattern of new issuance remained light compared with long-term historical trends. Due to their insured mandate and the continued severe decline in insured issuance, finding appropriate insured municipal bonds, especially new insured issues, remained a challenge for these Funds during the first two months of this period. Over the past few years, most municipal bond insurers had their credit ratings downgraded and only one insurer currently insures new municipal bonds. As a result, the supply of insured municipal securities decreased dramatically. During November and December 2011, issuance of new insured paper totaled just over $3 billion, accounting for approximately 4.5% of total municipal issuance during that time, compared with historical levels approaching 50%. The combination of comparatively light municipal supply, little insured issuance and relatively lower yields meant few attractive opportunities for these Funds during November and December 2011.

In view of this situation, in October 2011, the Funds’ Board of Directors/Trustees approved changes to the Funds’ investment policy regarding insured municipal securities. Effective January 2, 2012, the Funds eliminated the policy requiring them to invest at least 80% of their managed assets in municipal securities covered by insurance. This change was designed to provide more flexibility regarding the types of securities available for investment. This does not represent a change in investment objectives; each

|  | Nuveen Investments |  | 5

Fund will continue to invest substantially all of its assets in a portfolio of investment-grade quality municipal securities.

Following the change to these Funds’ investment policy, our purchase activity increased, as we worked to enhance the Funds’ credit and sector diversification. One of the areas where we were more active was the health care sector, which had been underutilized in these Funds under the insured mandate and which we believed offered good opportunities. We also found value in water and sewer, transportation (particularly airports and toll roads), tobacco and higher education credits and in tax-supported bonds. Although the pattern of issuance tended to be shorter on the yield curve during this period due to an increase in refunding activity, our focus generally remained on longer maturities in order to take advantage of attractive yields at the longer end of the municipal yield curve. The purchase of longer bonds also provided some protection for the Funds’ duration and yield curve positioning. We also added slightly more yield to the Funds, buying bonds rated A and BBB. Overall, we continued to take a bottom-up approach to discovering sectors that appeared undervalued as well as individual credits that had the potential to perform well over the long term.

Cash for new purchases during this period was generated primarily by the proceeds from called and maturing bonds, which we worked to redeploy to keep the Funds fully invested. Approximately half of the new municipal bonds issued during this period came from borrowers that were calling existing debt and refinancing at lower rates. This refunding activity provided a meaningful source of liquidity, which was beneficial as we began to transition the Funds from insured to non-insured. In addition, NIF and NPX, which are now structured as Funds that do not hold any bonds subject to the alternative minimum tax (AMT), sold all of their AMT holdings by March 31, 2012, and reinvested the proceeds into bonds offering federal tax-exempt income. This provided additional opportunities to restructure these two Funds.

As of April 30, 2012, all six of these Funds continued to use inverse floating rate securities. We employ inverse floaters for a variety of reasons, including duration management, income enhancement and total return enhancement.

For the six months ended April 30, 2012, the cumulative returns on common share net asset value (NAV) for these six Funds exceeded the returns for the Standard & Poor’s (S&P) Municipal Bond Index and the S&P Municipal Bond Insured Index. For the same period, the Funds underperformed the average return for the Lipper General & Insured Leveraged Municipal Debt Funds Classification Average.

Key management factors that influenced the Funds’ returns during this period included duration and yield curve positioning, credit exposure and sector allocation. The use of regulatory leverage also was an important positive factor affecting the Funds’ performance. Leverage is discussed in more detail later in this report.

During this period, municipal bonds with longer maturities generally outperformed those with shorter maturities. Overall, credits at the longest end of the municipal yield curve posted the strongest returns, while bonds at the shortest end produced the weakest results. Among these Funds, NQI, NIF and NPX were the most advantageously positioned in terms of duration and yield curve exposure, with greater exposure to the longer parts of the yield curve that performed well. Holdings of non-callable zero coupon bonds, which outperformed during this period due to their long durations, also boosted the performance of NQI and NPX. In contrast, both NVG and NEA, which were introduced in March and November 2002, respectively, have reached the ten-year point

|  | Nuveen Investments |  | 7

of the bond market cycle where holdings of bonds with short call dates typically increases. This hampered their performance during this period. NEA, which had the shortest duration among the six Funds, was the most negatively impacted by its positioning. In general, variations in duration and yield curve positioning among the Funds accounted for the majority of the differences in performance.

Credit exposure was also an important factor in performance during these six months, as lower quality bonds generally outperformed higher quality bonds. This outperformance was due in part to the greater demand for lower rated bonds as investors looked for investment vehicles offering higher yields. As investors became more comfortable taking on additional investment risk, credit spreads, or the difference in yield spreads between U.S. Treasury securities and comparable investments such as municipal bonds, narrowed through a variety of rating categories. Over the past few years, bonds that matured or were called from these Funds’ portfolios and not replaced due to the insured mandate caused their credit weightings to shift toward the upper end of the quality spectrum. While we added to the Funds’ lower rated holdings following the change in investment policy, these Funds generally continued to be significantly over-weight in bonds rated AA, which detracted from their performance during this period. NEA’s performance also was hampered by the largest exposure to AAA rated bonds among these six Funds. These allocations were offset to a certain extent by the positive influence of the Funds’ exposures to the lower rated credit spectrum.

Holdings that generally made positive contributions to the Funds’ returns during this period included health care (including hospitals), transportation and education credits. All of these Funds, particularly NQI, NPX and NVG, benefited from their weightings in the health care sector. In addition, the returns of NQI and NPX were boosted by their holdings of toll road bonds. Tobacco bonds backed by the 1998 master settlement agreement also were one of the top performing market segments, as these bonds benefited from several market developments, including increased demand for higher-yielding investments by investors who became less risk averse. In addition, based on recent data showing that cigarette sales had fallen less steeply than anticipated, the 46 states participating in the agreement stand to receive increased payments from the tobacco companies. Benefiting from the recent change in investment policy, NIO, NIF, NVG and NEA now have allocations in lower rated tobacco bonds as of April 30, 2012. NQI and NPX do not hold any lower rated tobacco bonds.

8 |  | Nuveen Investments |  |

In contrast, pre-refunded bonds, which are often backed by U.S. Treasury securities, were the poorest performing market segment during this period. The underperformance of these bonds can be attributed primarily to their shorter effective maturities and higher credit quality. As of April 30, 2012, NEA had the largest exposure to pre-refunded bonds, while NQI had the smallest allocation. General obligation and other tax-supported bonds as well as utilities and housing credits also lagged the performance of the general municipal market for this period. These Funds generally had relatively light exposures to housing, which limited the impact of the performance of this sector.

FUND POLICY CHANGES

On October 28, 2011, the Funds’ Board of Directors/Trustees approved changes to each Fund’s investment policy regarding its investment in insured municipal securities. These changes were designed to provide the Adviser with more flexibility regarding the types of securities available for investment by each Fund.

Effective January 2, 2012, each Fund eliminated the investment policy requiring it, under normal circumstances, to invest at least 80% of its managed assets in municipal securities that are covered by insurance guaranteeing the timely payment of principal and interest. Over the past few years, most municipal bond insurers have had their credit ratings downgraded and only one insurer is currently insuring new municipal bonds. As a result, the supply of insured municipal securities has decreased dramatically and the long-term viability of the municipal bond insurance market is uncertain. The Funds have not changed their investment objective and will continue to invest substantially all of their assets in a portfolio of investment grade quality municipal securities.

Concurrent with the investment policy changes, the Funds have changed their names as follows:

• | Nuveen Insured Quality Municipal Fund, Inc. (NQI) changed to Nuveen Quality Municipal Fund, Inc. (NQI)

• | Nuveen Insured Municipal Opportunity Fund, Inc. (NIO) changed to Nuveen Municipal Opportunity Fund, Inc. (NIO)

• | Nuveen Premier Insured Municipal Income Fund, Inc. (NIF) changed to Nuveen Premier Municipal Opportunity Fund, Inc. (NIF)

|  | Nuveen Investments |  | 9

• | Nuveen Insured Premium Income Municipal Fund 2 (NPX) changed to Nuveen Premium Income Municipal Opportunity Fund (NPX)

• | Nuveen Insured Dividend Advantage Municipal Fund (NVG) changed to Nuveen Dividend Advantage Municipal Income Fund (NVG); and

• | Nuveen Insured Tax-Free Advantage Municipal Fund (NEA) changed to Nuveen AMT-Free Municipal Income Fund (NEA)

In addition, each Fund changed its non-fundamental investment policy requiring each Fund to invest in municipal securities rated at least investment grade at the time of investment. Each Fund adopted a new policy to, under normal circumstances, invest at least 80% of its managed assets in investment grade securities that, at the time of investment, are rated within the four highest grades (Baa or BBB or better) by at least one nationally recognized statistical ratings organization (“NRSRO”) or are unrated but judged to be of comparable quality by the Fund’s investment adviser. Under the new policy, each Fund may invest up to 20% of its managed assets in municipal securities that at the time of investment are rated below investment grade or are unrated but judged to be of comparable quality by the Fund’s investment adviser. No more than 10% of each Fund’s managed assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by the Fund’s investment adviser.

APPROVED FUND REORGANIZATIONS

On June 22, 2012, the Funds’ Board of Directors/Trustees approved a series of reorganizations for certain Funds included in this report. The reorganizations are intended to create a single larger Fund, which would potentially offer shareholders the following benefits:

• | Lower Fund expense ratios (excluding the effects of leverage), as fixed costs are spread over a larger asset base;

• | Enhanced secondary market trading, as larger Funds potentially make it easier for investors to buy and sell Fund shares;

• | Lower per share trading costs through reduced bid/ask spreads due to a larger common share float; and

• | Increased Fund flexibility in managing the structure and cost of leverage over time.

10 |  | Nuveen Investments |  |

The approved reorganizations are as follows:

Acquired Funds |  | Symbol |  | Acquiring Fund |  | Symbol
• Nuveen Premier Municipal Opportunity Fund, Inc. |  | NIF |  | Nuveen AMT-Free Municipal Income Fund |  | NEA
• Nuveen Premier Income Municipal Opportunity Fund |  | NPX |  |  |  |

If shareholders approve the reorganizations, and upon the closing of the reorganizations, the Acquired Funds will transfer substantially all of their assets to the Acquiring Fund in exchange for common and preferred shares of the Acquiring Fund, and the assumption by the Acquiring Fund of the liabilities of the Acquired Funds. The Acquired Funds will then be liquidated, dissolved and terminated in accordance with their Declaration of Trust.

Fund Leverage and

Other Information

IMPACT OF THE FUNDS’ LEVERAGE STRATEGIES ON PERFORMANCE

One important factor impacting the returns of all these Funds relative to the comparative indexes was the Funds’ use of leverage. The Funds use leverage because their managers believe that, over time, leveraging provides opportunities for additional income and total return for common shareholders. However, use of leverage also can expose common shareholders to additional volatility. For example, as the prices of securities held by a Fund decline, the negative impact of these valuation changes on common share net asset value and common shareholder total return is magnified by the use of leverage. Conversely, leverage may enhance common share returns during periods when the prices of securities held by a Fund generally are rising. Leverage made a positive contribution to the performance of these Funds over this reporting period.

THE FUNDS’ REGULATORY LEVERAGE

RISK CONSIDERATIONS

Fund shares are not guaranteed or endorsed by any bank or other insured depository institution, and are not federally insured by the Federal Deposit Insurance Corporation. Past performance is no guarantee of future results. Fund common shares are subject to a variety of risks, including:

Investment and Market Risk. An investment in common shares is subject to investment risk, including the possible loss of the entire principal amount that you invest. Your investment in common shares represents an indirect investment in the municipal securities owned by the Fund, which generally trade in the over-the-counter markets. Your common shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions.

Price Risk. Shares of closed-end investment companies like these Funds frequently trade at a discount to their NAV. Your common shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions.

Leverage Risk. Each Fund’s use of leverage creates the possibility of higher volatility for the Fund’s per share NAV, market price, distributions and returns. There is no assurance that a Fund’s leveraging strategy will be successful.

Tax Risk. The tax treatment of Fund distributions may be affected by new IRS interpretations of the Internal Revenue Code and future changes in tax laws and regulations.

Issuer Credit Risk. This is the risk that a security in a Fund’s portfolio will fail to make dividend or interest payments when due.

Interest Rate Risk. Fixed-income securities such as bonds, preferred, convertible and other debt securities will decline in value if market interest rates rise.

Reinvestment Risk. If market interest rates decline, income earned from a Fund’s portfolio may be reinvested at rates below that of the original bond that generated the income.

Call Risk or Prepayment Risk. Issuers may exercise their option to prepay principal earlier than scheduled, forcing a Fund to reinvest in lower-yielding securities.

Inverse Floater Risk. The Funds may invest in inverse floaters. Due to their leveraged nature, these investments can greatly increase a Fund’s exposure to interest rate risk and credit risk. In addition, investments in inverse floaters involve the risk that the Fund could lose more than its original principal investment.

Common Share Dividend

and Price Information

DIVIDEND INFORMATION

The monthly dividends of all six Funds in this report remained stable throughout the six-month reporting period ended April 30, 2012.

Due to normal portfolio activity, common shareholders of the following Funds received capital gains and/or net ordinary income distributions in December 2011 as follows:

|  | Long-Term Capital Gains (per share) |  |  | Short-Term Capital Gains and/or Ordinary Income (per share) |
NQI |  |  | — |  |  | $ | 0.0026 |
NIO |  | $ | 0.0026 |  |  |  | — |
NVG |  | $ | 0.0413 |  |  |  | — |

All of the Funds in this report seek to pay stable dividends at rates that reflect each Fund’s past results and projected future performance. During certain periods, each Fund may pay dividends at a rate that may be more or less than the amount of net investment income actually earned by the Fund during the period. If a Fund has cumulatively earned more than it has paid in dividends, it holds the excess in reserve as undistributed net investment income (UNII) as part of the Fund’s NAV. Conversely, if a Fund has cumulatively paid dividends in excess of its earnings, the excess constitutes negative UNII that is likewise reflected in the Fund’s NAV. Each Fund will, over time, pay all of its net investment income as dividends to shareholders. As of April 30, 2012, all six of the Funds in this report had positive UNII balances, based upon our best estimate, for tax purposes and positive UNII balances for financial reporting purposes.

COMMON SHARE REPURCHASES AND PRICE INFORMATION

As of April 30, 2012, and since the inception of the Funds’ repurchase programs, the Funds have cumulatively repurchased and retired their common shares as shown in the accompanying table. Since the inception of the Funds’ repurchase programs, NQI, NIF, and NPX have not repurchased any of their outstanding common shares.

Fund |  | Common Shares Repurchased and Retired |  |  | % of Outstanding Common Shares |
NIO |  |  | 2,900 |  |  |  | 0.0% |
NVG |  |  | 10,400 |  |  |  | 0.0% |
NEA |  |  | 19,300 |  |  |  | 0.1% |

During the six-month reporting period, the Funds did not repurchase and retire any of their outstanding common shares.

(a) | The amounts shown are based on Common share equivalents.

(b) | Total Return Based on Market Value is the combination of changes in the market price per share and the effect of reinvested dividend income and reinvested capital gains distributions, if any, at the average price paid per share at the time of reinvestment. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last dividend declared in the period may take place over several days, and in some instances may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation.

Total returns are not annualized.

Total Return Based on Common Share Net Asset Value is the combination of changes in Common share net asset value, reinvested dividend income at net asset value and reinvested capital gains distributions at net asset value, if any. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending net asset value. The actual reinvest price for the last dividend declared in the period may often be based on the Fund’s market price (and not its net asset value), and therefore may be different from the price used in the calculation. Total returns are not annualized.

(a) | The amounts shown are based on Common share equivalents.

(b) | Total Return Based on Market Value is the combination of changes in the market price per share and the effect of reinvested dividend income and reinvested capital gains distributions, if any, at the average price paid per share at the time of reinvestment. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last dividend declared in the period may take place over several days, and in some instances may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation. Total returns are not annualized.

Total Return Based on Common Share Net Asset Value is the combination of changes in Common share net asset value, reinvested dividend income at net asset value and reinvested capital gains distributions at net asset value, if any. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending net asset value. The actual reinvest price for the last dividend declared in the period may often be based on the Fund’s market price (and not its net asset value), and therefore may be different from the price used in the calculation. Total returns are not annualized.

1. General Information and Significant Accounting Policies

General Information

The funds covered in this report and their corresponding Common share stock exchange symbols are Nuveen Quality Municipal Fund, Inc. (NQI), Nuveen Municipal Opportunity Fund, Inc. (NIO), Nuveen Premier Municipal Opportunity Fund, Inc. (NIF), Nuveen Premium Income Municipal Opportunity Fund (NPX), Nuveen Dividend Advantage Municipal Income Fund (NVG) and Nuveen AMT-Free Municipal Income Fund (NEA) (each a “Fund” and collectively, the “Funds”). Common shares of Quality (NQI), Opportunity (NIO), Premier Opportunity (NIF) and Premium Opportunity (NPX) are traded on the New York Stock Exchange (“NYSE”) while Common shares of Dividend Advantage (NVG) and AMT-Free Income (NEA) are traded on the NYSE Amex. The Funds are registered under the Investment Company Act of 1940, as amended, as closed-end registered investment companies.

Each Fund seeks to provide current income exempt from regular federal income tax, and in the case of AMT-Free Income (NEA) the alternative minimum tax applicable to individuals, by investing primarily in a portfolio of municipal obligations issued by state and local government authorities or certain U.S. territories.

Policy Changes

On October 28, 2011, the Funds’ Board of Directors/Trustees approved changes to each Fund’s investment policy regarding its investment in insured municipal securities. These changes were designed to provide Nuveen Fund Advisors, Inc. (the “Adviser”), a wholly-owned subsidiary of Nuveen Investments Inc. (“Nuveen”), with more flexibility regarding the types of securities available for investment by each Fund.

On January 2, 2012, each Fund eliminated the investment policy requiring it, under normal circumstances, to invest at least 80% of its managed assets (as defined in Footnote 7 – Management Fees and Other Transactions with Affiliates) in municipal securities that are covered by insurance guaranteeing the timely payment of principal and interest. Since 2007, most municipal bond insurers have had their credit ratings downgraded and only one insurer is currently insuring new municipal bonds. As a result, the supply of insured municipal securities has decreased dramatically and the long-term viability of the municipal bond insurance market is uncertain. The Funds did not change their investment objective and continue to invest substantially all of their assets in a portfolio of investment grade quality municipal securities.

Concurrent with the investment policy changes, the Funds changed their names as follows:

• | Nuveen Insured Quality Municipal Fund, Inc. (NQI) changed to Nuveen Quality Municipal Fund, Inc. (NQI),

• | Nuveen Insured Municipal Opportunity Fund, Inc. (NIO) changed to Nuveen Municipal Opportunity Fund, Inc. (NIO),

• | Nuveen Premier Insured Municipal Income Fund, Inc. (NIF) changed to Nuveen Premier Municipal Opportunity Fund, Inc. (NIF),

• | Nuveen Insured Premium Income Municipal Fund 2 (NPX) changed to Nuveen Premium Income Municipal Opportunity Fund, Inc. (NPX),

• | Nuveen Insured Dividend Advantage Municipal Fund (NVG) changed to Nuveen Dividend Advantage Municipal Income Fund (NVG) and

• | Nuveen Insured Tax-Free Advantage Municipal Fund (NEA) changed to Nuveen AMT-Free Municipal Income Fund (NEA).

In addition, each Fund changed its non-fundamental investment policy requiring each Fund to invest in municipal securities rated at least investment grade at the time of investment. Each Fund adopted a new policy to, under normal circumstances, invest at least 80% of its managed assets in investment grade securities that, at the time of investment, are rated within the four highest grades (Baa or BBB or better) by at least one nationally recognized statistical ratings organization (“NRSRO”) or are unrated but judged to be of comparable quality by the Adviser. Under the new policy, each Fund may invest up to 20% of its managed assets in municipal securities that at the time of investment are rated below investment grade or are unrated but judged to be of comparable quality by the Adviser. No more than 10% of each Fund’s managed assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by the Adviser.

Significant Accounting Policies

The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”).

100 |  | Nuveen Investments |  |

Investment Valuation

Prices of municipal bonds are provided by a pricing service approved by the Funds’ Board of Directors/Trustees. These securities are generally classified as Level 2 for fair value measurement purposes. The pricing service establishes a security’s fair value using methods that may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. In pricing certain securities, particularly less liquid and lower quality securities, the pricing service may consider information about a security, its issuer, or market activity, provided by the Adviser. These securities are generally classified as Level 2 or Level 3 depending on the priority of the significant inputs. Investments in investment companies are valued at their respective net asset values on the valuation date. These investment vehicles are generally classified as Level 1.

Certain securities may not be able to be priced by the pre-established pricing methods as described above. Such securities may be valued by the Funds’ Board of Directors/Trustees or its designee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; debt securities that have gone into default and for which there is no current market quotation; a security whose market price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund’s net asset value (as may be the case in non-U.S. markets on which the security is primarily traded) or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, is not deemed to reflect the security’s fair value. As a general principle, the fair value of a security would appear to be the amount that the owner might reasonably expect to receive for it in a current sale. A variety of factors may be considered in determining the fair value of such securities, which may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. These securities are generally classified as Level 2 or Level 3 depending on the priority of the significant inputs. Regardless of the method employed to value a particular security, all valuations are subject to review by the Funds’ Board of Directors/Trustees or its designee.

Refer to Footnote 2 – Fair Value Measurements for further details on the leveling of securities held by the Funds as of the end of the reporting period.

Investment Transactions

Investment transactions are recorded on a trade date basis. Realized gains and losses from transactions are determined on the specific identification method, which is the same basis used for federal income tax purposes. Investments purchased on a when-issued/delayed delivery basis may have extended settlement periods. Any investments so purchased are subject to market fluctuation during this period. The Funds have instructed the custodian to segregate assets with a current value at least equal to the amount of the when-issued/delayed delivery purchase commitments. At April 30, 2012, Quality (NQI), Opportunity (NIO), Premier Opportunity (NIF), Dividend Advantage (NVG) and AMT-Free Income (NEA) had outstanding when-issued/delayed delivery purchase commitments of $7,696,956, $45,276,790, $2,750,350, $10,353,996 and $14,875,520, respectively. There were no such outstanding purchase commitments in Premium Opportunity (NPX).

Investment Income

Dividend income is recorded on the ex-dividend date. Investment income, which reflects the amortization of premiums and includes accretion of discounts for financial reporting purposes, is recorded on an accrual basis. Investment income also reflects paydown gains and losses, if any.

Professional Fees

Professional fees presented on the Statement of Operations consist of legal fees incurred in the normal course of operations, audit fees, tax consulting fees and, in some cases, workout expenditures. Workout expenditures are incurred in an attempt to protect or enhance an investment, or to pursue other claims or legal actions on behalf of Fund shareholders. Legal fee refund presented in the Statement of Operations reflects a refund of workout expenditures paid in a prior reporting period.

Income Taxes

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all of its net investment income and net capital gains to shareholders and to otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies (“RICs”). Therefore, no federal income tax provision is required. Furthermore, each Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from regular federal income tax, and in the case of AMT-Free Income (NEA) the alternative minimum tax applicable to individuals, to retain such tax-exempt status when distributed to shareholders of the Funds. Net realized capital gains and ordinary income distributions paid by the Funds are subject to federal taxation.

For all open tax years and all major taxing jurisdictions, management of the Funds has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. Open tax years are those that are open for examination by taxing authorities (i.e., generally the last four tax year ends and the interim tax period since then). Furthermore, management of the Funds is also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

|  | Financial Statements (Unaudited) (continued)

Dividends and Distributions to Common Shareholders

Dividends from net investment income are declared monthly. Net realized capital gains and/or market discount from investment transactions, if any, are distributed to shareholders at least annually. Furthermore, capital gains are distributed only to the extent they exceed available capital loss carryforwards.

Distributions to Common shareholders of net investment income, net realized capital gains and/or market discount, if any, are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

Auction Rate Preferred Shares

Each Fund is authorized to issue Auction Rate Preferred Shares (“ARPS”). As of October 31, 2011, the Funds redeemed all of their outstanding ARPS, at liquidation value.

MuniFund Term Preferred Shares

The following Funds have issued and outstanding MuniFund Term Preferred (“MTP”) Shares, with a $10 stated (“par”) value per share. Proceeds from the issuance of MTP Shares, net of offering expenses, were used to redeem all, or a portion of, each Fund’s outstanding ARPS. Each Fund’s MTP Shares are issued in one Series. Dividends on MTP Shares, which are recognized as interest expense for financial reporting purposes, are paid monthly at a fixed annual rate, subject to adjustments in certain circumstances. The MTP Shares trade on the NYSE. As of April 30, 2012, the number of MTP Shares outstanding, annual interest rate and the NYSE “ticker” symbol for each Fund’s series of MTP Shares are as follows:

|  | Dividend Advantage (NVG) |  |  | AMT-Free Income (NEA) |
|  | Shares Outstanding |  |  | Annual Interest Rate |  |  | NYSE Ticker |  |  | Shares Outstanding |  |  | Annual Interest Rate |  |  | NYSE Ticker |
Series: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
2014 |  |  | 10,800,000 |  |  |  | 2.95 | % |  |  | NVG Pr C |  |  |  | — |  |  |  | — | % |  |  | — |
2015 |  |  | — |  |  |  | — |  |  |  | — |  |  |  | 8,300,000 |  |  |  | 2.85 |  |  |  | NEA Pr C |

Each Fund is obligated to redeem its MTP Shares by the date as specified in its offering document (“Term Redemption Date”), unless earlier redeemed or repurchased by the Fund. MTP Shares are subject to optional and mandatory redemption in certain circumstances. MTP Shares will be subject to redemption at the option of each Fund (“Optional Redemption Date”), subject to a payment of premium for one year following the Optional Redemption Date (“Premium Expiration Date”), and at par thereafter. MTP Shares also will be subject to redemption, at the option of each Fund, at par in the event of certain changes in the credit rating of the MTP Shares. Each Fund may be obligated to redeem certain of the MTP Shares if the Fund fails to maintain certain asset coverage and leverage ratio requirements and such failures are not cured by the applicable cure date. The redemption price per share is equal to the sum of the liquidation value per share plus any accumulated but unpaid dividends. The Term Redemption Date, Optional Redemption Date and Premium Expiration Date for each Fund’s series of MTP Shares are as follows:

|  | Dividend Advantage (NVG) Series 2014 |  |  | AMT-Free Income (NEA) Series 2015 |
Term Redemption Date |  |  | November 1, 2014 |  |  |  | February 1, 2015 |
Optional Redemption Date |  |  | November 1, 2010 |  |  |  | February 1, 2011 |
Premium Expiration Date |  |  | October 31, 2011 |  |  |  | January 31, 2012 |

The average liquidation value for all series of MTP Shares outstanding for each Fund during the six months ended April 30, 2012, was as follows:

|  | Dividend Advantage (NVG) |  |  | AMT-Free Income (NEA) |
Average liquidation value of MTP Shares outstanding |  | $ | 108,000,000 |  |  | $ | 83,000,000 |

For financial reporting purposes only, the liquidation value of MTP Shares is recorded as a liability on the Statement of Assets and Liabilities. Unpaid dividends on MTP Shares are recognized as a component of “Interest payable” on the Statement of Assets and Liabilities. Dividends paid on MTP Shares are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations.

Nuveen has agreed that net amounts earned by Nuveen as underwriter of each Fund’s MTP Share offering would be credited to the Funds, and would be recorded as reductions of offering costs recognized by the Funds. During the six months ended April 30, 2012, Nuveen earned no net underwriting amounts on the Funds’ MTP Shares.

Variable Rate MuniFund Term Preferred Shares

The following Funds have issued and outstanding Variable Rate MuniFund Term Preferred (“VMTP”) Shares, with $100,000 liquidation value per share. Quality (NQI), Dividend Advantage (NVG) and AMT-Free Income (NEA) issued their VMTP Shares in a privately negotiated offering during February 2011, September 2011 and July 2011, respectively. Proceeds from the issuance of VMTP Shares, net of offering expenses, were used to redeem all or a portion of, the remainder of each Fund’s outstanding ARPS. Each Fund’s VMTP Shares were offered to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933. As of April 30, 2012, the number of VMTP Shares outstanding, at liquidation value, for each Fund is as follows:

|  | Quality (NQI) |  |  | Dividend Advantage (NVG) |  |  | AMT-Free Income (NEA) |
Series 2014 |  |  | $240,400,000 |  |  |  | $92,500,000 |  |  |  | $67,600,000 |

Each Fund is obligated to redeem its VMTP Shares by the date as specified in its offering document (“Term Redemption Date”), unless earlier redeemed or repurchased by the Fund. VMTP Shares are subject to optional and mandatory redemption in certain circumstances . The VMTP Shares are subject to redemption at the option of each Fund (“Optional Redemption Date”), subject to payment of premium for one year following the Optional Redemption Date (“Premium Expiration Date”), and at par thereafter. Each Fund may be obligated to redeem certain of the VMTP Shares if the Fund fails to maintain certain asset coverage and leverage ratio requirements and such failures are not cured by the applicable cure date. The redemption price per share is equal to the sum of the liquidation value per share plus any accumulated but unpaid dividends. The Term Redemption Date, Optional Redemption Date and Premium Expiration Date for each Fund’s VMTP Shares are as follows:

|  | Quality (NQI) |  |  | Dividend Advantage (NVG) |  |  | AMT-Free Income (NEA) |
Term Redemption Date |  |  | March 1, 2014 |  |  |  | October 1, 2014 |  |  |  | August 1, 2014 |
Optional Redemption Date |  |  | March 1, 2012 |  |  |  | October 1, 2012 |  |  |  | August 1, 2012 |
Premium Expiration Date |  |  | February 29, 2012 |  |  |  | September 30, 2012 |  |  |  | July 31, 2012 |

The average liquidation value of VMTP Shares outstanding and annualized dividend rate of VMTP Shares for each Fund during the six months ended April 30, 2012, were as follows:

|  | Quality (NQI) |  |  | Dividend Advantage (NVG) |  |  | AMT-Free Income (NEA) |
Average liquidation Value of VMTP Shares outstanding |  |  | $240,400,000 |  |  |  | $92,500,000 |  |  |  | $67,600,000 |
Annualized dividend rate |  |  | 1.39% |  |  |  | 1.14% |  |  |  | 1.19% |

Dividends on the VMTP Shares (which are treated as interest payments for financial reporting purposes) are set weekly.

For financial reporting purposes only, the liquidation value of VMTP Shares is recorded as a liability on the Statement of Assets and Liabilities. Unpaid dividends on VMTP Shares are recognized as a component of “Interest payable” on the Statement of Assets and Liabilities. Dividends paid on VMTP Shares are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations.

Variable Rate Demand Preferred Shares

The following Funds have issued and outstanding Variable Rate Demand Preferred (“VRDP”) Shares, with a $100,000 liquidation value per share. Opportunity (NIO), Premier Opportunity (NIF) and Premium Opportunity (NPX) issued their VRDP Shares in a privately negotiated offering during December 2010, December 2010 and August 2008, respectively. Concurrent with renewing agreements with the liquidity provider for its VRDP Shares in June 2010, Premium Opportunity (NPX) exchanged all its 2,190 Series 1 VRDP Shares for 2,190 Series 2 VRDP Shares. The principal difference in terms between Series 1 and Series 2 VRDP Shares is the requirement that the Fund redeem VRDP Shares owned by the liquidity provider if the VRDP Shares have been owned by the liquidity provider through six months of continuous, unsuccessful remarketing. Proceeds of each Fund’s offering were used to redeem all or a portion of, the remainder of each Fund’s outstanding ARPS. The VRDP Shares were offered to qualified institutional buyers

|  | Nuveen Investments |  | 103

|  | Notes to
|  | Financial Statements (Unaudited) (continued)

pursuant to Rule 144A under the Securities Act of 1933. As of April 30, 2012, the number of VRDP Shares outstanding and maturity date for each Fund are as follows:

|  | Opportunity (NIO) |  |  | Premier Opportunity (NIF) |  |  | Premium Opportunity (NPX) |
Series |  |  | 1 |  |  |  | 1 |  |  |  | 2 |
Shares outstanding |  |  | 6,672 |  |  |  | 1,309 |  |  |  | 2,190 |
Maturity |  |  | December 1, 2040 |  |  |  | December 1, 2040 |  |  |  | August 1, 2038 |

VRDP Shares include a liquidity feature that allows VRDP shareholders to have their shares purchased by a liquidity provider with whom each Fund has contracted in the event that purchase orders for VRDP Shares in a remarketing are not sufficient in number to be matched with the sale orders in that remarketing. Each Fund is required to redeem any VRDP Shares that are still owned by the liquidity provider after six months of continuous, unsuccessful remarketing.

Dividends on the VRDP Shares (which are treated as interest payments for financial reporting purposes) are set weekly at a rate established by a remarketing agent; therefore, the market value of the VRDP Shares is expected to approximate its liquidation value. If remarketings for VRDP Shares are continuously unsuccessful for six months, the maximum rate is designed to escalate according to a specified schedule in order to enhance the remarketing agent’s ability to successfully remarket the VRDP Shares.

Subject to certain conditions, VRDP Shares may be redeemed, in whole or in part, at any time at the option of each Fund. Each Fund may also redeem certain of the VRDP Shares if the Fund fails to maintain certain asset coverage requirements and such failures are not cured by the applicable cure date. The redemption price per share is equal to the sum of the liquidation value per share plus any accumulated but unpaid dividends.

The average liquidation value outstanding and annualized dividend rate of VRDP Shares for each Fund during the six months ended April 30, 2012, were as follows:

|  | Opportunity (NIO) |  |  | Premier Opportunity (NIF) |  |  | Premium Opportunity (NPX) |
Average liquidation value outstanding |  |  | 667,200,000 |  |  |  | 130,900,000 |  |  |  | 219,000,000 |
Annualized dividend rate |  |  | 0.28% |  |  |  | 0.28% |  |  |  | 0.27% |

For financial reporting purposes only, the liquidation value of VRDP Shares is recognized as a liability on the Statement of Assets and Liabilities. Unpaid dividends on VRDP Shares are recognized as a component of “Interest payable” on the Statement of Assets and Liabilities. Dividends paid on the VRDP Shares are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations. In addition to interest expense, each Fund also pays a per annum liquidity fee to the liquidity provider as well as a remarketing fee, which are recognized as components of “Fees on VRDP Shares” on the Statement of Operations.

Insurance

Since 2007, the financial status of most major municipal bond insurers has deteriorated substantially, and some insurers have gone out of business, rendering worthless the insurance policies they had written. Under normal circumstances, and during the period November 1, 2011 through January 2, 2012, each Fund invests at least 80% of its managed assets (as defined in Footnote 7 – Management Fees and Other Transactions with Affiliates) in municipal securities that were covered by insurance guaranteeing the timely payment of principal and interest. In addition, during the period November 1, 2011 through January 2, 2012, each Fund invested in municipal securities that, at the time of investment was rated investment grade (including (i) bonds insured by investment grade rated insurers or are rated investment grade; (ii) unrated bonds that are judged to be investment grade by the Adviser; and (iii) escrowed bonds). Ratings below BBB by one or more national rating agencies are considered to be below investment grade.

Inverse Floating Rate Securities

Each Fund is authorized to invest in inverse floating rate securities. An inverse floating rate security is created by depositing a municipal bond, typically with a fixed interest rate, into a special purpose trust created by a broker-dealer. In turn, this trust (a) issues floating rate certificates, in face amounts equal to some fraction of the deposited bond’s par amount or market value, that typically pay short-term tax-exempt interest rates to third parties, and (b) issues to a long-term investor (such as one of the Funds) an inverse floating rate certificate (sometimes referred to as an “inverse floater”) that represents all remaining or residual interest in the trust. The income received by the inverse floater holder varies inversely with the short-term rate paid to the floating rate certificates’ holders, and in most circumstances the inverse floater holder bears substantially all of the underlying bond’s downside investment risk and also benefits disproportionately from any potential appreciation of the underlying bond’s value. The price of an inverse floating rate security will be more volatile than that of the underlying bond because the interest rate is dependent on not only the fixed coupon rate of the

104 |  | Nuveen Investments |  |

underlying bond but also on the short-term interest paid on the floating rate certificates, and because the inverse floating rate security essentially bears the risk of loss of the greater face value of the underlying bond.

A Fund may purchase an inverse floating rate security in a secondary market transaction without first owning the underlying bond (referred to as an “externally-deposited inverse floater”), or instead by first selling a fixed-rate bond to a broker-dealer for deposit into the special purpose trust and receiving in turn the residual interest in the trust (referred to as a “self-deposited inverse floater”). The inverse floater held by a Fund gives the Fund the right (a) to cause the holders of the floating rate certificates to tender their notes at par, and (b) to have the broker transfer the fixed-rate bond held by the trust to the Fund, thereby collapsing the trust. An investment in an externally-deposited inverse floater is identified in the Portfolio of Investments as “(IF) – Inverse floating rate investment.” An investment in a self-deposited inverse floater is accounted for as a financing transaction. In such instances, a fixed-rate bond deposited into a special purpose trust is identified in the Portfolio of Investments as “(UB) – Underlying bond of an inverse floating rate trust reflected as a financing transaction,” with the Fund accounting for the short-term floating rate certificates issued by the trust as “Floating rate obligations” on the Statement of Assets and Liabilities. In addition, the Fund reflects in “Investment Income” the entire earnings of the underlying bond and recognizes the related interest paid to the holders of the short-term floating rate certificates as a component of “Interest expense and amortization of offering costs” on the Statement of Operations.

During the six months ended April 30, 2012, each Fund invested in externally-deposited inverse floaters and/or self-deposited inverse floaters.

Each Fund may also enter into shortfall and forbearance agreements (sometimes referred to as a “recourse trust” or “credit recovery swap”) (such agreements referred to herein as “Recourse Trusts”) with a broker-dealer by which a Fund agrees to reimburse the broker-dealer, in certain circumstances, for the difference between the liquidation value of the fixed-rate bond held by the trust and the liquidation value of the floating rate certificates issued by the trust plus any shortfalls in interest cash flows. Under these agreements, a Fund’s potential exposure to losses related to or on inverse floaters may increase beyond the value of a Fund’s inverse floater investments as a Fund may potentially be liable to fulfill all amounts owed to holders of the floating rate certificates. At period end, any such shortfall is recognized as “Unrealized depreciation on Recourse Trusts” on the Statement of Assets and Liabilities.

At April 30, 2012, each Fund’s maximum exposure to externally-deposited Recourse Trusts, was as follows:

|  | Quality (NQI) |  |  | Opportunity (NIO) |  |  | Premier Opportunity (NIF) |  |  | Premium Opportunity (NPX) |  |  | Dividend Advantage (NVG) |  |  | AMT-Free Income (NEA) |
Maximum exposure to Recourse Trusts |  |  | $26,610,000 |  |  |  | $40,430,000 |  |  |  | $15,375,000 |  |  |  | $14,845,000 |  |  |  | $6,665,000 |  |  |  | $6,665,000 |

The average floating rate obligations outstanding and average annual interest rate and fees related to self-deposited inverse floaters during the six months ended April 30, 2012, were as follows:

|  | Quality (NQI) |  |  | Opportunity (NIO) |  |  | Premier Opportunity (NIF) |  |  | Premium Opportunity (NPX) |  |  | Dividend Advantage (NVG) |  |  | AMT-Free Income (NEA) |
Average floating rate obligations outstanding |  | $ | 52,456,099 |  |  | $ | 105,390,614 |  |  | $ | 19,000,000 |  |  | $ | 56,858,132 |  |  | $ | 28,413,334 |  |  | $ | 13,040,000 |
Average annual interest rate and fees |  |  | 0.48% |  |  |  | 0.52% |  |  |  | 0.46% |  |  |  | 0.46% |  |  |  | 0.58% |  |  |  | 0.61% |

Derivative Financial Instruments

Each Fund is authorized to invest in certain derivative instruments, including foreign currency forwards, futures, options and swap contracts. Although the Funds are authorized to invest in such financial instruments, and may do so in the future, they did not make any such investments during the six months ended April 30, 2012.

Market and Counterparty Credit Risk

In the normal course of business each Fund may invest in financial instruments and enter into financial transactions where risk of potential loss exists due to changes in the market (market risk) or failure of the other party to the transaction to perform (counterparty credit risk). The potential loss could exceed the value of the financial assets recorded on the financial statements. Financial assets, which potentially expose each Fund to counterparty credit risk, consist principally of cash due from counterparties on forward, option and swap transactions, when applicable. The extent of each Fund’s exposure to counterparty credit risk in respect to these financial assets approximates their carrying value as recorded on the Statement of Assets and Liabilities. Futures contracts, when applicable, expose a Fund to minimal counterparty credit risk as they are exchange traded and the exchange’s clearinghouse, which is counterparty to all exchange traded futures, guarantees the futures contracts against default.

Each Fund helps manage counterparty credit risk by entering into agreements only with counterparties the Adviser believes have the financial resources to honor their obligations and by having the Adviser monitor the financial stability of the counterparties. Additionally, counterparties may be required to pledge collateral daily (based on the daily valuation of the financial asset) on behalf of each Fund with a value approximately equal to the amount of any unrealized gain above a pre-determined threshold. Reciprocally, when each Fund has an unrealized loss, the Funds have instructed the custodian to pledge assets of the Funds as collateral with a value approximately equal to the amount of the unrealized loss above a pre-

|  | Nuveen Investments |  | 105

|  | Notes to
|  | Financial Statements (Unaudited) (continued)

determined threshold. Collateral pledges are monitored and subsequently adjusted if and when the valuations fluctuate, either up or down, by at least the pre-determined threshold amount.

Zero Coupon Securities

Each Fund is authorized to invest in zero coupon securities. A zero coupon security does not pay a regular interest coupon to its holders during the life of the security. Tax-exempt income to the holder of the security comes from accretion of the difference between the original purchase price of the security at issuance and the par value of the security at maturity and is effectively paid at maturity. The market prices of zero coupon securities generally are more volatile than the market prices of securities that pay interest periodically.

Offering Costs

Costs incurred by Dividend Advantage (NVG) and AMT-Free Income (NEA) in connection with their offerings of MTP Shares ($1,875,000 and $1,605,000, respectively) were recorded as deferred charges, which are being amortized over the life of the shares. Costs incurred by Quality (NQI), Dividend Advantage (NVG) and AMT-Free Income (NEA) in connection with their VMTP Shares ($1,120,000, $485,000 and $180,000, respectively) were recorded as deferred charges, which are being amortized over the life of the shares. Costs incurred by Opportunity (NIO), Premier Opportunity (NIF) and Premium Opportunity (NPX) in connection with their offerings of VRDP Shares ($2,645,000, $755,000 and $2,535,000, respectively) were recorded as deferred charges, which are being amortized over the life of the shares. Each Fund’s amortized deferred charges are recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations.

Custodian Fee Credit

Each Fund has an arrangement with the custodian bank whereby certain custodian fees and expenses are reduced by net credits earned on each Fund’s cash on deposit with the bank. Such deposit arrangements are an alternative to overnight investments. Credits for cash balances may be offset by charges for any days on which a Fund overdraws its account at the custodian bank.

Indemnifications

Under the Funds’ organizational documents, their officers and directors/trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In addition, in the normal course of business, the Funds enter into contracts that provide general indemnifications to other parties. The Funds’ maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred. However, the Funds have not had prior claims or losses pursuant to these contracts and expect the risk of loss to be remote.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets applicable to Common shares from operations during the reporting period. Actual results may differ from those estimates.

2. Fair Value Measurements

Fair value is defined as the price that the Funds would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad levels listed below:

Level 1 – Quoted prices in active markets for identical securities.

Level 2 – Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).

Level 3 – Significant unobservable inputs (including management’s assumptions in determining the fair value of investments).

During the six months ended April 30, 2012, the Funds recognized no significant transfers to or from Level 1 or Level 2. Transfers in and/or out of Level 3 are shown using end of period values.

3. Derivative Instruments and Hedging Activities

The Funds record derivative instruments at fair value, with changes in fair value recognized on the Statement of Operations, when applicable. Even though the Funds’ investments in derivatives may represent economic hedges, they are not considered to be hedge transactions for financial reporting purposes. The Funds did not invest in derivative instruments during the six months ended April 30, 2012.

6. Income Tax Information

The following information is presented on an income tax basis. Differences between amounts for financial statement and federal income tax purposes are primarily due to timing differences in recognizing taxable market discount, timing differences in recognizing certain gains and losses on investment transactions and the treatment of investments in inverse floating rate securities reflected as financing transactions, if any. To the extent that differences arise that are permanent in nature, such amounts are reclassified within the capital accounts as detailed below. Temporary differences do not require reclassification. Temporary and permanent differences do not impact the net asset values of the Funds.

7. Management Fees and Other Transactions with Affiliates

Each Fund’s management fee consists of two components – a fund-level fee, based only on the amount of assets within the Fund, and a complex-level fee, based on the aggregate amount of all eligible fund assets managed by the Adviser. This pricing structure enables Fund shareholders to benefit from growth in the assets within their respective Fund as well as from growth in the amount of complex-wide assets managed by the Adviser.

The annual fund-level fee for each Fund, payable monthly, is calculated according to the following schedule:

Average Daily Managed Assets* |  | Quality (NQI) Opportunity (NIO) Premier Opportunity (NIF) Premium Opportunity (NPX) Fund-Level Fee Rate |
For the first $125 million |  |  | .4500% |
For the next $125 million |  |  | .4375 |
For the next $250 million |  |  | .4250 |
For the next $500 million |  |  | .4125 |
For the next $1 billion |  |  | .4000 |
For the next $3 billion |  |  | .3875 |
For managed assets over $5 billion |  |  | .3750 |

Average Daily Managed Assets* |  | Dividend Advantage (NVG) AMT-Free Income (NEA) Fund-Level Fee Rate |
For the first $125 million |  |  | .4500% |
For the next $125 million |  |  | .4375 |
For the next $250 million |  |  | .4250 |
For the next $500 million |  |  | .4125 |
For the next $1 billion |  |  | .4000 |
For managed assets over $2 billion |  |  | .3750 |

|  | Nuveen Investments |  | 111

|  | Notes to
|  | Financial Statements (Unaudited) (continued)

The annual complex-level fee for each Fund, payable monthly, is calculated according to the following schedule:

Complex-Level Managed Asset Breakpoint Level* |  | Effective Rate at Breakpoint Level |
$55 billion |  |  | .2000% |
$56 billion |  |  | .1996 |
$57 billion |  |  | .1989 |
$60 billion |  |  | .1961 |
$63 billion |  |  | .1931 |
$66 billion |  |  | .1900 |
$71 billion |  |  | .1851 |
$76 billion |  |  | .1806 |
$80 billion |  |  | .1773 |
$91 billion |  |  | .1691 |
$125 billion |  |  | .1599 |
$200 billion |  |  | .1505 |
$250 billion |  |  | .1469 |
$300 billion |  |  | .1445 |

* | For the fund-level and complex-level fees, managed assets include closed-end fund assets managed by the Adviser that are attributable to financial leverage. For these purposes, financial leverage includes the funds’ use of preferred stock and borrowings and certain investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities, subject to an agreement by the Adviser as to certain funds to limit the amount of such assets for determining managed assets in certain circumstances. The complex-level fee is calculated based upon the aggregate daily managed assets of all Nuveen Funds that constitute “eligible assets.” Eligible assets do not include assets attributable to investments in other Nuveen Funds or assets in excess of $2 billion added to the Nuveen Fund complex in connection with the Adviser’s assumption of the management of the former First American Funds effective January 1, 2011. As of April 30, 2012, the complex-level fee rate for these Funds was .1724%.

The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. The Adviser is responsible for each Fund’s overall strategy and asset allocation decisions. The Adviser has entered into sub-advisory agreements with Nuveen Asset Management, LLC (“the Sub-Adviser”), a wholly-owned subsidiary of the Adviser, under which the Sub-Adviser manages the investment portfolios of the Funds. The Sub-Adviser is compensated for its services to the Funds from the management fees paid to the Adviser.

The Funds pay no compensation directly to those of its directors/trustees who are affiliated with the Adviser or to its officers, all of whom receive remuneration for their services to the Funds from the Adviser or its affiliates. The Board of Directors/Trustees has adopted a deferred compensation plan for independent directors/trustees that enables directors/trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen-advised funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen-advised funds.

For the first ten years of Dividend Advantage’s (NVG) operations, the Adviser has agreed to reimburse the Fund, as a percentage of average daily managed assets, for fees and expenses in the amounts and for the time periods set forth below:

Year Ending March 31, |  |  |  | Year Ending March 31, |  |
2002* |  | .30% |  | 2008 |  | .25%
2003 |  | .30 |  | 2009 |  | .20
2004 |  | .30 |  | 2010 |  | .15
2005 |  | .30 |  | 2011 |  | .10
2006 |  | .30 |  | 2012 |  | .05
2007 |  | .30 |  |  |  |

* | From the commencement of operations.

The Adviser has not agreed to reimburse Dividend Advantage (NVG) for any portion of its fees and expenses beyond March 31, 2012.

8. New Accounting Pronouncements

Fair Value Measurements and Disclosures

On May 12, 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-04 (“ASU No. 2011-04”) modifying Topic 820, Fair Value Measurements and Disclosures. At the same time, the International Accounting Standards Board (“IASB”) issued International Financial Reporting Standard (“IFRS”) 13, Fair Value Measurement. The objective of the FASB and IASB is convergence of their guidance on fair value measurements and disclosures. Specifically, ASU No. 2011-04 requires reporting entities to disclose i) the amounts of any transfers between Level 1 and Level 2 and the reasons for the transfers and ii) for Level 3 fair value measurements, a) quantitative information about significant

112 |  | Nuveen Investments |  |

unobservable inputs used, b) a description of the valuation processes used by the reporting entity and c) a narrative description of the sensitivity of the fair value measurement to changes in unobservable inputs if a change in those inputs might result in a significantly higher or lower fair value measurement. The effective date of ASU No. 2011-04 is for interim and annual periods beginning after December 15, 2011. At this time, management is evaluating the implications of this guidance and the impact it will have to the financial statement amounts and footnote disclosures, if any.

9. Subsequent Event

Approved Fund Reorganizations

On June 22, 2012, the Funds’ Board of Directors/Trustees approved a series of reorganizations for certain Funds included in this report. The reorganizations are intended to create a single larger Fund, which would potentially offer shareholders the following benefits:

• Lower Fund expense ratios (excluding the effects of leverage), as fixed costs are spread over a larger asset base;

• Enhanced secondary market trading, as larger Funds potentially make it easier for investors to buy and sell Fund shares;

• Lower per share trading costs through reduced bid/ask spreads due to a larger common share float; and

• Increased Fund flexibility in managing the structure and cost of leverage over time.

The approved reorganizations are as follows:

Acquired Funds |  | Acquiring Fund
• Premier Opportunity (NIF) |  | •AMT-FreeIncome (NEA)
• Premium Opportunity (NPX) |  |

If shareholders approve the reorganizations, and upon the closing of the reorganizations, the Acquired Funds will transfer substantially all of their assets to the Acquiring Fund in exchange for common and preferred shares of the Acquiring Fund, and the assumption by the Acquiring Fund of the liabilities of the Acquired Funds. The Acquired Funds will then be liquidated, dissolved and terminated in accordance with their Declaration of Trust.

Reinvest Automatically,

Easily and Conveniently

Nuveen makes reinvesting easy. A phone call is all it takes to set up your reinvestment account.

Nuveen Closed-End Funds Automatic Reinvestment Plan

Your Nuveen Closed-End Fund allows you to conveniently reinvest distributions in additional Fund shares.

By choosing to reinvest, you’ll be able to invest money regularly and automatically, and watch your investment grow through the power of compounding. Just like distributions in cash, there may be times when income or capital gains taxes may be payable on distributions that are reinvested.

It is important to note that an automatic reinvestment plan does not ensure a profit, nor does it protect you against loss in a declining market.

Easy and convenient

To make recordkeeping easy and convenient, each month you’ll receive a statement showing your total distributions, the date of investment, the shares acquired and the price per share, and the total number of shares you own.

How shares are purchased

The shares you acquire by reinvesting will either be purchased on the open market or newly issued by the Fund. If the shares are trading at or above net asset value at the time of valuation, the Fund will issue new shares at the greater of the net asset value or 95% of the then-current market price. If the shares are trading at less than net asset value, shares for your account will be purchased on the open market. If the Plan Agent begins purchasing Fund shares on the open market while shares are trading below net asset value, but the Fund’s shares subsequently trade at or above their net asset value before the Plan Agent is able to complete its purchases, the Plan Agent may cease open-market purchases and may invest the uninvested portion of the distribution in newly-issued Fund shares at a price equal to the greater of the shares’ net asset value or 95% of the shares’ market value on the last business day immediately prior to the purchase date. Distributions received to purchase shares in the open market will normally be invested shortly after the distribution payment date. No interest will be paid on distributions awaiting reinvestment. Because the market price of the shares may increase before purchases are completed, the average purchase price per share may

114 |  | Nuveen Investments |  |

exceed the market price at the time of valuation, resulting in the acquisition of fewer shares than if the distribution had been paid in shares issued by the Fund. A pro rata portion of any applicable brokerage commissions on open market purchases will be paid by Plan participants. These commissions usually will be lower than those charged on individual transactions.

Flexible

You may change your distribution option or withdraw from the Plan at any time, should your needs or situation change.

You can reinvest whether your shares are registered in your name, or in the name of a brokerage firm, bank, or other nominee. Ask your investment advisor if his or her firm will participate on your behalf. Participants whose shares are registered in the name of one firm may not be able to transfer the shares to another firm and continue to participate in the Plan.

The Fund reserves the right to amend or terminate the Plan at any time. Although the Fund reserves the right to amend the Plan to include a service charge payable by the participants, there is no direct service charge to participants in the Plan at this time.

Glossary of Terms

Used in this Report

n |  | Auction Rate Bond: An auction rate bond is a security whose interest payments are adjusted periodically through an auction process, which process typically also serves as a means for buying and selling the bond. Auctions that fail to attract enough buyers for all the shares offered for sale are deemed to have “failed,” with current holders receiving a formula-based interest rate until the next scheduled auction.

n |  | Average Annual Total Return: This is a commonly used method to express an investment’s performance over a particular, usually multi-year time period. It expresses the return that would have been necessary each year to equal the investment’s actual cumulative performance (including change in NAV or market price and reinvested dividends and capital gains distributions, if any) over the time period being considered.

n |  | Average Effective Maturity: The market-value-weighted average of the effective maturity dates of the individual securities including cash. In the case of a bond that has been advance-refunded to a call date, the effective maturity is the date on which the bond is scheduled to be redeemed using the proceeds of an escrow account. In most other cases the effective maturity is the stated maturity date of the security.

n |  | Effective Leverage: Effective leverage is a Fund’s effective economic leverage, and includes both regulatory leverage and the leverage effects of certain derivative investments in the Fund’s portfolio. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values, in addition to any regulatory leverage.

n |  | Inverse Floating Rate Securities: Inverse floating rate securities, also known as inverse floaters or tender option bonds (TOBs), are created by depositing a municipal bond, typically with a fixed interest rate, into a special purpose trust created by a broker-dealer. This trust, in turn, (a) issues floating rate certificates typically paying short-term tax-exempt interest rates to third parties in amounts equal to some fraction of the deposited bond’s par amount or market value, and (b) issues an inverse floating rate certificate (sometimes referred to as an “inverse floater”) to an investor (such as a Fund) interested in gaining investment exposure to a long-term municipal bond. The income received by the holder of the inverse floater varies inversely with the short-term rate paid to the floating rate certificates’ holders, and in most circum- stances the holder of the inverse floater bears substantially all of the underlying bond’s downside investment risk. The holder of the inverse floater typically also benefits disproportionately from any potential appreciation of the underlying bond’s value. Hence, an inverse floater essentially represents an investment in the underlying bond on a leveraged basis.

116 |  | Nuveen Investments |  |

n |  | Leverage: Using borrowed money to invest in securities or other assets, seeking to increase the return of an investment or portfolio.

n |  | Leverage-Adjusted Duration: Duration is a measure of the expected period over which a bond’s principal and interest will be paid, and consequently is a measure of the sensitivity of a bond’s or bond Fund’s value to changes when market interest rates change. Generally, the longer a bond’s or Fund’s duration, the more the price of the bond or Fund will change as interest rates change. Leverage-adjusted duration takes into account the leveraging process for a Fund and therefore is longer than the duration of the Fund’s portfolio of bonds.

n |  | Lipper General & Insured Leveraged Municipal Debt Funds Classification Average: Calculated using the returns of all closed-end funds in this category. Lipper returns account for the effects of management fees and assume reinvestment of distributions, but do not reflect any applicable sales charges.

n |  | Market Yield (also known as Dividend Yield or Current Yield): An investment’s current annualized dividend divided by its current market price.

n |  | Net Asset Value (NAV): The net market value of all securities held in a portfolio.

n |  | Net Asset Value (NAV) Per Share: The market value of one share of a mutual fund or closed-end fund. For a Fund, the NAV is calculated daily by taking the Fund’s total assets (securities, cash, and accrued earnings), subtracting the Fund’s liabilities, and dividing by the number of shares outstanding.

n |  | Pre-Refunding: Pre-Refunding, also known as advanced refundings or refinancings, is a procedure used by state and local governments to refinance municipal bonds to lower interest expenses. The issuer sells new bonds with a lower yield and uses the proceeds to buy U.S. Treasury securities, the interest from which is used to make payments on the higher-yielding bonds. Because of this collateral, pre-refunding generally raises a bond’s credit rating and thus its value.

n |  | Regulatory Leverage: Regulatory Leverage consists of preferred shares issued by or borrowings of a Fund. Both of these are part of a Fund’s capital structure. Regulatory leverage is sometimes referred to as “’40 Act Leverage” and is subject to asset coverage limits set in the Investment Company Act of 1940.

n |  | Standard & Poor’s (S&P) Municipal Bond Index: An unleveraged, market value-weighted index designed to measure the performance of the tax-exempt, investment-grade U.S. municipal bond market. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.

n |  | Standard & Poor’s (S&P) Municipal Bond Insured Index: An unleveraged, market value-weighted index designed to measure the performance of the tax-exempt, insured U.S. municipal bond market. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.

n |  | Taxable-Equivalent Yield: The yield necessary from a fully taxable investment to equal, on an after-tax basis, the yield of a municipal bond investment.

|  | Nuveen Investments |  | 117

Glossary of Terms

Used in this Report (continued)

n |  | Zero Coupon Bond: A zero coupon bond does not pay a regular interest coupon to its holders during the life of the bond. Tax-exempt income to the holder of the bond comes from accretion of the difference between the original purchase price of the bond at issuance and the par value of the bond at maturity and is effectively paid at maturity. The market prices of zero coupon bonds generally are more volatile than the market prices of bonds that pay interest periodically.

PART C

OTHER INFORMATION

Item 15. Indemnification

Section 4 of Article XII of the Registrant’s Declaration of Trust provides as follows: Subject to the exceptions and limitations contained in this Section 4, every person who is, or has been, a Trustee, officer, employee or agent of the Trust, including persons who serve at the request of the Trust as directors, trustees, officers, employees or agents of another organization in which the Trust has an interest as a shareholder, creditor or otherwise (hereinafter referred to as a “Covered Person”), shall be indemnified by the Trust to the fullest extent permitted by law against liability and against all expenses reasonably incurred or paid by him in connection with any claim, action, suit or proceeding in which he becomes involved as a party or otherwise by virtue of his being or having been such a Trustee, director, officer, employee or agent and against amounts paid or incurred by him in settlement thereof.

No indemnification shall be provided hereunder to a Covered Person: (a) against any liability to the Trust or its Shareholders by reason of a final adjudication by the court or other body before which the proceeding was brought that he engaged in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office; (b) with respect to any matter as to which he shall have been finally adjudicated not to have acted in good faith in the reasonable belief that his action was in the best interests of the Trust; or (c) in the event of a settlement or other disposition not involving a final adjudication (as provided in paragraph (a) or (b)) and resulting in a payment by a Covered Person, unless there has been either a determination that such Covered Person did not engage in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office by the court or other body approving the settlement or other disposition or a reasonable determination, based on a review of readily available facts (as opposed to a full trial-type inquiry), that he did not engage in such conduct: (i) by a vote of a majority of the Disinterested Trustees acting on the matter (provided that a majority of the Disinterested Trustees then in office act on the matter); or (ii) by written opinion of independent legal counsel.

The rights of indemnification herein provided may be insured against by policies maintained by the Trust, shall be severable, shall not affect any other rights to which any Covered Person may now or hereafter be entitled, shall continue as to a person who has ceased to be such a Covered Person and shall inure to the benefit of the heirs, executors and administrators of such a person. Nothing contained herein shall affect any rights to indemnification to which Trust personnel other than Covered Persons may be entitled by contract or otherwise under law.

Expenses of preparation and presentation of a defense to any claim, action, suit or proceeding subject to a claim for indemnification under this Section 4 shall be advanced by the Trust prior to final disposition thereof upon receipt of an undertaking by or on behalf of the recipient to repay such amount if it is ultimately determined that he is not entitled to indemnification under this Section 4, provided that either: (a) such undertaking is secured by a surety bond or some other appropriate security or the Trust shall be insured against losses arising out of any such advances; or (b) a majority of the Disinterested Trustees acting on the matter (provided that a majority of the Disinterested Trustees then in office act on the matter) or independent legal counsel in a written opinion shall determine, based upon a review of the readily available facts (as opposed to a full trial-type inquiry), that there is reason to believe that the recipient ultimately will be found entitled to indemnification. As used in this Section 4, a “Disinterested Trustee” is one (x) who is not an Interested Person of the Trust

C-1

(including anyone, as such Disinterested Trustee, who has been exempted from being an Interested Person by any rule, regulation or order of the Commission), and (y) against whom none of such actions, suits or other proceedings or another action, suit or other proceeding on the same or similar grounds is then or has been pending.

As used in this Section 4, the words “claim,” “action,” “suit” or “proceeding” shall apply to all claims, actions, suits, proceedings (civil, criminal, administrative or other, including appeals), actual or threatened; and the words “liability” and “expenses” shall include without limitation, attorneys’ fees, costs, judgments, amounts paid in settlement, fines penalties and other liabilities.

The trustees and officers of the Registrant are covered by the Mutual Fund Professional Liability policy in the aggregate amount of $70,000,000 against liability and expenses of claims of wrongful acts arising out of their position with the Registrant and other Nuveen funds, except for matters that involve willful acts, bad faith, gross negligence and willful disregard of duty (i.e., where the insured did not act in good faith for a purpose he or she reasonably believed to be in the best interest of the Registrant or where he or she had reasonable cause to believe this conduct was unlawful). The policy has a $2,500,000 deductible for operational failures (after the deductible is satisfied, the insurer would cover 80% of any operational failure claims and the Fund would be liable for 20% of any such claims) and $1,000,000 deductible for all other claims, with $0 deductible for individual insureds.

Insofar as indemnification for liability arising under the Securities Act of 1933, as amended (the “Securities Act”), may be permitted to trustees, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that, in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a trustee, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such trustee, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
