IMPORTANT NOTICE TO SHAREHOLDERS OF

NUVEEN MASSACHUSETTS QUALITY MUNICIPAL INCOME FUND (NMT)

AND

NUVEEN AMT-FREE QUALITY MUNICIPAL INCOME FUND (NEA)

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

[●], 2023

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

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

A. | You are receiving the Joint Proxy Statement/Prospectus as a holder of common shares of Nuveen Massachusetts Quality Municipal Income Fund (the “Target Fund”) or as a holder of preferred shares of Nuveen AMT-Free Quality Municipal Income Fund (the “Acquiring Fund” and together with the Target Fund, the “Funds” or each individually, a “Fund”) in connection with the solicitation of proxies by each Fund’s Board of Trustees (each, a “Board” and each Trustee, a “Board Member”) for use at the annual meeting of shareholders of the Target Fund and at a special meeting of shareholders of the Acquiring Fund (each, a “Meeting” and together, the “Meetings”).

| At the Meetings, shareholders of the Funds will be asked to vote on the following proposals:

| • |  | (Common and preferred shareholders of the Target Fund) to approve an Agreement and Plan of Merger (the “Agreement”) pursuant to which the Target Fund will merge with and into a wholly-owned subsidiary of the Acquiring Fund (the “Merger”);

| • |  | (Preferred shareholders of the Acquiring Fund) to approve the Agreement with respect to the Merger; and

| • |  | (Common and preferred shareholders of the Target Fund) to elect members of the Board. (The list of specific nominees is contained in the enclosed Joint Proxy Statement/Prospectus.)

| Shareholders of the Target Fund are being solicited to vote on the election of six (6) Board Members who have been nominated for election at the Meeting. These Board Members would continue in office in the event the Merger is not consummated in a timely manner.

| Each Fund’s Board unanimously recommends that you vote FOR each proposal that is applicable to your Fund.

Proposal Regarding the Merger

Q. | Why has each Fund’s Board recommended the Merger proposal?

A. | Nuveen Fund Advisors, LLC (“Nuveen Fund Advisors”), the Funds’ investment adviser, recommended the proposed Merger. Each Fund’s Board considered the Merger and determined that the Merger would be in the best interests of its Fund. Based on information provided by Nuveen Fund Advisors, the Target Fund’s Board

| believes that the proposed Merger may benefit the common shareholders of the Target Fund in a number of ways, including, among other things:

| • |  | The potential for higher common share net earnings and distribution levels following the Merger, due in part to the Acquiring Fund’s ability to invest to a greater degree in lower rated securities and a geographically diverse national portfolio, as well as operating economies from the combined fund’s greater scale;

| • |  | Greater secondary market liquidity and improved secondary market trading for common shares as a result of the combined fund’s greater share volume, which may lead to narrower bid-ask spreads and smaller trade-to-trade price movements;

| • |  | The potential for a narrower trading discount as a result of the Acquiring Fund’s common shares trading at a discount that, on average, has been lower over the prior twelve months from June 30, 2023 than that of the Target Fund’s common shares;

| • |  | Increased portfolio and leverage management flexibility due to the significantly larger asset base of the combined fund and the Acquiring Fund’s national mandate with greater flexibility to invest in lower rated securities; and

| • |  | Lower net operating expenses, excluding the costs of leverage, as certain fixed costs are spread over a larger asset base.

| The Target Fund’s Board considered that a greater percentage of the Acquiring Fund’s portfolio may be allocated to lower rated municipal securities relative to the amount permitted by the policies of the Target Fund, and recognized that investments in lower rated securities are subject to higher risks than investments in higher rated securities. The Target Fund’s Board also noted that as a result of the Merger and the Acquiring Fund’s national mandate, it was expected that the benefit to Target Fund shareholders of any state tax exemption from investing in a state-specific municipal fund would be lost or largely unavailable.

| With respect to holders of preferred shares of the Target Fund, the Target Fund’s Board considered that, upon the closing of the Merger, holders of preferred shares of the Target Fund outstanding immediately prior to the closing will receive, on a one-for-one basis, newly issued preferred shares of the Acquiring Fund having substantially similar terms to those of the preferred shares of the Target Fund immediately prior to the closing of the Merger.

| Based on information provided by Nuveen Fund Advisors, the Acquiring Fund’s Board considered that the Acquiring Fund may benefit in the near term from a modest increase in common share net earnings and operating efficiencies and over the long term from increased investment capital, which allows the Acquiring Fund to pursue additional investment opportunities. With respect to holders of preferred shares of the Acquiring Fund, the Acquiring Fund’s Board considered that the outstanding preferred shares of the Acquiring Fund and any preferred shares of the Acquiring Fund to be issued in the Merger would have equal priority with each other as to the payment of dividends and distributions of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund.

| For these reasons, each Fund’s Board has determined that the Merger is in the best interest of its Fund and has approved the Merger.

Q. | How will preferred shareholders be affected by the Merger?

A. | The Acquiring Fund has four series of MuniFund Preferred Shares (“MFP Shares”) outstanding, one series of Adjustable Rate MuniFund Term Preferred Shares (“AMTP Shares”) outstanding, and four series of Variable Rate Demand Preferred Shares (“VRDP Shares”) outstanding, and these shares are expected to remain outstanding following the Merger. The Target Fund has one series of VRDP Shares outstanding. Upon the closing of the Merger, holders of VRDP Shares of the Target Fund then outstanding will receive, on a one-for-one basis, newly issued VRDP Shares of the Acquiring Fund having substantially similar terms to those of the VRDP Shares of the Target Fund immediately prior to the closing of the Merger. The

ii

| outstanding preferred shares of the Acquiring Fund and any preferred shares to be issued by the Acquiring Fund in the Merger will have equal priority with each other and with any other preferred shares that the Acquiring Fund may issue in the future as to the payment of dividends and the distribution of assets upon the dissolution, liquidation or winding up of the affairs of the Acquiring Fund.

| Following the Merger, to the extent the Acquiring Fund issues any new preferred shares in the Merger, holders of preferred shares of the combined fund may hold a smaller percentage of the outstanding preferred shares of the combined fund as compared to their percentage holdings of their respective Fund prior to the Merger. Additionally, the combined fund has multiple series and types of preferred shares outstanding. The different types of preferred shares have different characteristics and features, which are described in more detail in the Joint Proxy Statement/Prospectus. See “Proposal No. 1—C. Information About the Merger—Description of VRDP Shares to Be Issued by the Acquiring Fund” beginning on page [●], “Additional Information About the Acquiring Fund—Description of Outstanding Acquiring Fund MFP Shares” beginning on page [●], “Additional Information About the Acquiring Fund—Description of Outstanding Acquiring Fund AMTP Shares” beginning on page [●] and “Additional Information About the Acquiring Fund—Description of Outstanding Acquiring Fund VRDP Shares” beginning on page [●].

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

A. | The Funds have similar investment objectives, policies and risks, but there are differences. Each Fund seeks to provide tax-exempt current income by investing primarily in municipal securities. However, there are differences between the investment objectives, policies and risks of the Funds. The principal similarities and differences between the Funds’ investment objectives, policies and risks are as follows:

| • |  | The Target Fund is a state-specific municipal fund that seeks to provide current income exempt from both regular federal income tax and Massachusetts personal income taxes, while the Acquiring Fund is a national municipal fund that seeks to provide current income exempt from regular federal income tax and the federal alternative minimum tax applicable to individuals.

| • |  | The Target Fund invests primarily in Massachusetts municipal obligations and is subject to economic, political and other risks of a single state, while the Acquiring Fund may invest in municipal obligations of any U.S. state or territory.

| • |  | The Target Fund may invest up to 20% of its managed assets in municipal securities that, at the time of investment, are rated below investment grade (Ba or BB or lower) or are unrated but judged to be of comparable quality by the sub-adviser. The Acquiring Fund may invest up to 35% of its managed assets in securities rated, at the time of investment, below the three highest grades (Baa or BBB or lower) by at least one nationally recognized statistical rating organization. As discussed on page [●] of the Joint Proxy Statement/Prospectus, investments in lower rated securities are subject to higher risks than investments in higher rated securities, including a higher risk that the issuer will be unable to pay interest or principal when due.

| • |  | Each Fund is a diversified, closed-end management investment company and currently employs leverage through the issuance of preferred shares and the use of inverse floating rate securities.

| See “Proposal No. 1—A. Synopsis—Comparison of the Acquiring Fund and the Target Fund—Investment Objectives and Policies” and “Proposal No. 1—A. Synopsis—Comparative Risk Information” for more information.

Q. | How will the Merger impact fees and expenses?

A. | As discussed above, the Target Fund’s Board considered that, due to the greater asset base of the combined fund, the Merger is expected to result in economies of scale and a resulting reduction in certain operating expenses. Based on information in the Comparative Fee Table, the pro forma annualized expense ratio, including the costs of leverage, of the combined fund following the Merger is estimated to be 25 basis points (0.25%) higher than the total expense ratio of the Target Fund. Based on information in

iii

| the Comparative Fee Table, the pro forma expense ratio, excluding the costs of leverage, of the combined fund following the Merger is estimated to decline up to 20 basis points (0.20%) compared to the total expense ratio of the Target Fund. Leverage costs reflect the forms and sources of leverage in effect for each specified period and such costs will vary over time.

| See the Comparative Fee Table on page [●] of the enclosed Joint Proxy Statement/Prospectus for more detailed information regarding fees and expenses. See also “Additional Information About the Acquiring Fund” on page [●].

Q. | Will shareholders of the Funds have to pay any fees or expenses in connection with the Merger?

A. | Yes. The Funds, and indirectly their common shareholders, will bear the costs of the Merger, whether or not the Merger is consummated. The allocation of the costs of the Merger to the Funds is based on the expected benefits of the Merger to common shareholders of the Funds following the Merger, including operating expense savings, improvements in the secondary trading market for common shares and the impact on common share net earnings. Preferred shareholders will not bear any costs of the Merger.

| The costs of the Merger are estimated to be $1,325,000, but the actual costs may be higher or lower than that amount. These costs represent the estimated nonrecurring expenses of the Funds in carrying out their obligations under the Agreement and Plan of Merger and consist of management’s estimate of professional service fees, printing costs and mailing charges related to the proposed Merger. Based on the expected benefits of the Merger to common shareholders of each Fund, the Target Fund is expected to be allocated $845,000 and the Acquiring Fund is expected to be allocated $480,000 of the estimated expenses in connection with the Merger (0.74% and 0.01%, respectively, of the Target Fund’s and the Acquiring Fund’s average net assets applicable to common shares for the six months ended April 30, 2023). If the Merger is not consummated for any reason, including because the requisite shareholder approvals are not obtained, each of the Funds, and common shareholders of each of the Funds indirectly, will still bear the costs of the Merger.

Q. | Will the Merger constitute a taxable event for the Target Fund’s shareholders?

A. | No. As a non-waivable condition to closing, each Fund will receive an opinion of counsel, subject to certain representations, assumptions and conditions, substantially to the effect that the proposed Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. It is expected that shareholders of the Target Fund who receive Acquiring Fund shares pursuant to the Merger will recognize no gain or loss for federal income tax purposes as a direct result of the Merger, except to the extent that the Target Fund common shareholder receives cash in lieu of a fractional Acquiring Fund common share. Prior to the closing of the Merger, the Target Fund expects to declare a distribution to its common shareholders of all of its undistributed net investment income and net capital gains, if any. All or a portion of such distribution made by the Target Fund may be taxable to the Target Fund’s common shareholders for federal income tax purposes. If the Merger had occurred as of June 30, 2023, it is estimated that approximately 59% of the Target Fund’s investment portfolio would have been sold by the Acquiring Fund following the Merger. To the extent the Acquiring Fund sells securities following the Merger, the Acquiring Fund may recognize gains (including any built-in gain in the portfolio investments of the Target Fund that was unrealized at the time of the Merger), which may result in taxable distributions to Acquiring Fund shareholders (including former shareholders of the Target Fund who hold shares of the Acquiring Fund following the Merger).

iv

Q. | As a result of the Merger, will common shareholders of the Target Fund receive new shares of the Acquiring Fund?

A. | Yes. Upon the closing of the Merger, Target Fund common shareholders will become common shareholders of the Acquiring Fund. Holders of common shares of the Target Fund will receive newly issued common shares of the Acquiring Fund, with cash being distributed in lieu of fractional common shares. The aggregate net asset value, as of the close of trading on the business day immediately prior to the closing of the Merger, of the Acquiring Fund common shares received by the Target Fund’s common shareholders (including, for this purpose, fractional Acquiring Fund common shares to which common shareholders would be entitled) will be equal to the aggregate net asset value of the common shares of the Target Fund held by its shareholders as of such time. Fractional Acquiring Fund common shares due to Target Fund common shareholders will be aggregated and sold on the open market, and Target Fund common shareholders will receive cash in lieu of such fractional shares.

| Following the Merger, common shareholders of each Fund will hold a smaller percentage of the outstanding common shares of the combined fund as compared to their percentage holdings of their respective Fund prior to the Merger.

Q. | What will happen if the required shareholder approvals are not obtained?

A. | The closing of the Merger is subject to the satisfaction or waiver of certain closing conditions, which include customary closing conditions. In order for the Merger to occur, all requisite shareholder approvals must be obtained at the applicable Fund’s shareholder meeting, and certain other consents, confirmations and/or waivers from various third parties, including the liquidity providers and/or certain purchasers of the outstanding preferred shares of the Funds, must also be obtained. Because the closing of the Merger is contingent upon the Target Fund and the Acquiring Fund obtaining such shareholder approvals and satisfying (or obtaining the waiver of) other closing conditions, it is possible that the Merger will not occur even if shareholders of a Fund entitled to vote approve the Merger and a Fund satisfies all of its closing conditions if the other Fund does not obtain its requisite shareholder approvals or satisfy (or obtain the waiver of) its closing conditions. If the Merger is not consummated, the Board of the Target Fund may take such actions as it deems in the best interests of the Fund, including conducting additional solicitations with respect to the Merger proposal or continuing to operate the Target Fund as a standalone fund.

| The Funds believe that their respective preferred shares are held by a small number of 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, the approval by a Fund’s preferred shareholders required for the Merger to occur may turn on the exercise of voting or consent rights by such particular shareholder(s) and its or their determination as to the favorable view of the Merger with respect to its or their interests. The Funds exercise no influence or control over the determinations of such shareholders with respect to the Merger; there is no guarantee that such shareholders will vote to approve the Merger proposal.

Q. | What is the timetable for the Merger?

A. | If the shareholder approvals and other conditions to closing are satisfied (or waived), the Merger is expected to take effect on or about [●], 2023, or such other date as the parties may agree.

Q. | How does each Board recommend that shareholders vote on the Merger proposal?

A. | After careful consideration, each Board has determined that the Merger proposal is in the best interests of its Fund and recommends that you vote FOR such proposal.

Proposal No. 1. |  | (Target Fund and Acquiring Fund) To approve an Agreement and Plan of Merger that provides for: (i) the merger of the Target Fund with and into [●], a Massachusetts limited liability company and a wholly-owned subsidiary of the Acquiring Fund (the “Merger Sub”), and (ii) the conversion of the issued and outstanding common and preferred shares of beneficial interest of the Target Fund into, respectively, newly issued common and preferred shares of beneficial interest, par value $0.01 per share, of the Acquiring Fund (the “Merger”).

Board Members Lancellotta, Nelson, Toth and Young are nominees for election by the Target Fund’s common and preferred shareholders. Board Members Hunter and Moschner are nominees for election by the Target Fund’s preferred shareholders.

In addition to its common shares, each Fund has one or more series of preferred shares outstanding. The Target Fund has one series of Variable Rate Demand Preferred Shares (“VRDP Shares”) outstanding. The Acquiring Fund has four series of MuniFund Preferred Shares (“MFP Shares”) outstanding, one series of Adjustable Rate MuniFund Term Preferred Shares (“AMTP Shares”) outstanding and four series of VRDP Shares outstanding.

Shareholders of the Target Fund are being solicited to vote on the election of Board Members who have been nominated for election at the Meeting. These Board Members would continue in office in the event the Merger is not consummated in a timely manner. Only the common shareholders of the Target Fund and the preferred shareholders of the Acquiring Fund are being solicited to vote on Proposal No. 1 and only the common shareholders of the Target Fund are being solicited to vote on Proposal No. 2 described above pursuant to this Joint Proxy Statement/Prospectus. The preferred shareholders of the Target Fund are being solicited to vote on the proposals described above by means of a separate proxy statement.

A quorum of shareholders is required to take action at each Meeting. A majority (more than 50%) of the shares entitled to vote at a Meeting, represented in person (through participation by means of remote or “virtual” communication) or by proxy, will constitute a quorum of shareholders at that Meeting, except that for the election of the two Board Member nominees by holders of VRDP Shares of the Target Fund, 33 1/3% of the VRDP Shares entitled to vote and represented in person (through participation by means of remote or “virtual” communication) or by proxy will constitute a quorum. Votes cast in person (through participation by means of remote or “virtual” communication) or by proxy at each Meeting will be tabulated by the inspectors of election

ii

appointed for that Meeting. The inspectors of election will determine whether or not a quorum is present at the Meetings. For purposes of holding a Meeting, all properly submitted proxies will be counted as present for purposes of determining whether a quorum is present.

To be approved, the proposals must be approved by the Funds’ common and preferred shareholders present and entitled to vote at a Meeting as follows:

Proposal No. 1. |  | (Each Fund) With respect to the proposal regarding the Merger:

| • |  | With respect to the Target Fund, a majority (more than 50%) of the Target Fund’s outstanding common and preferred shares voting together as a single class, and by a majority (more than 50%) of the Target Fund’s preferred shareholders voting together as a single class; and

| • |  | With respect to the Acquiring Fund, a majority (more than 50%) of the Acquiring Fund’s preferred shares, voting together as a single class.

Proposal No. 2. |  | (Target Fund only) With respect to the proposal regarding the election of Target Fund Board Members:

| • |  | With respect to the one (1) Class I Board Member and three (3) Class II Board Members, the affirmative vote of a plurality (the greatest number of affirmative votes) of the Target Fund’s common and preferred shares, voting together as a single class; and

| • |  | With respect to the two (2) Board Members elected by preferred shareholders, the affirmative vote of a plurality of the Target Fund’s preferred shareholders, voting together as a single class.

Broker-dealer firms holding shares of a Fund in “street name” for the benefit of their customers and clients are generally required to request the instructions of such customers and clients on how to vote their shares before the Fund’s Meeting. The Funds understand that, under the rules of the New York Stock Exchange (the “NYSE”), such broker-dealer firms may, for certain “routine” matters, vote without instructions from their customers and clients if no instructions have been received prior to the date specified in the broker-dealer firm’s request for voting instructions. Broker non-votes typically occur when both routine and non-routine proposals are being considered at a meeting. Proposal No. 1 with respect to the Merger is considered a “non-routine” matter for which, under the rules of the NYSE, uninstructed shares may not be voted by broker-dealers, but Proposal No. 2 with respect to the election of Board Members is considered a “routine” matter, and beneficial owners who do not provide proxy instructions or who do not return a proxy card may have their shares voted by broker-dealer firms on Proposal No. 2 in the discretion of such broker-dealer firms. As a result, because the Target Fund’s common and preferred shareholders are being asked to vote on both Proposals Nos. 1 and 2, there may be broker non-votes received with respect to Proposal No. 1 at the Target Fund’s Meeting. Because Proposal No. 1 is a non-routine matter and the sole proposal at the Acquiring Fund Meeting, it is expected that there will be no broker non-votes at that Meeting.

Because the approval of Proposal No. 1 requires the approval by the holders of at least 50% of the Target Fund’s outstanding shares and by the holders of at least 50% of each Fund’s outstanding preferred shares, abstentions and broker non-votes, if any, will have the same effect as a vote against the proposal. Because the election of Board Members does not require that a minimum percentage of the Target Fund’s outstanding shares be voted in favor of any nominee, assuming the presence of a quorum, abstentions will have no effect on the outcome of the vote on Proposal No. 2.

Pursuant to Rule 452 of the NYSE, certain preferred shares held in “street name” as to which voting instructions have not been received from the beneficial owners or persons otherwise entitled to vote as of one

iii

business day before a Fund’s Meeting, or, if adjourned or postponed, one business day before the day to which the Meeting is adjourned or postponed, may be voted by the broker on a proposal in the same proportion as the votes cast by all holders of such preferred shares who have voted on a proposal. Rule 452 permits proportionate voting of the Acquiring Fund’s Series D MFP Shares and any series of the Acquiring Fund’s VRDP Shares (but not the Target Fund’s preferred shares or any other series of the Acquiring Fund’s preferred shares) with respect to a particular item if, among other things, (1) a minimum of 30% of that series of preferred shares has been voted by the holders of such shares with respect to such item, (2) less than 10% of that series of preferred shares has been voted by the holders of such shares against such item and (3) for any proposal as to which holders of common shares and preferred shares vote as a single class, holders of common shares approve a proposal. For the purpose of meeting the 30% test, abstentions will be treated as shares “voted,” and for the purpose of meeting the 10% test, abstentions will not be treated as shares “voted” against the item.

Broker-dealers who are not members of the NYSE may be subject to other rules, which may or may not permit them to vote your shares without instruction. We urge you to provide instructions to your broker or nominee so that your votes may be counted.

Those persons who were shareholders of record of a Fund as of the close of business on [●], 2023 and entitled to vote at the Fund’s Meeting 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 [●], 2023 for each Fund, the shares of the Funds issued and outstanding are as follows:

Fund (Ticker Symbol) |  | Common Shares(1) |  | AMTP Shares(1) |  | MFP Shares(1) |  | VRDP Shares(1)
Target Fund (NMT) |  | [●] |  | N/A |  | N/A |  | [●](Series 1)

(1) | The common shares of the Target Fund and the Acquiring Fund are listed on the NYSE. Upon the closing of the Merger, it is expected that the common shares of the Acquiring Fund will continue to be listed on the NYSE. None of the preferred shares are currently listed on any exchange.

PROPOSAL NO. 1—MERGER OF THE TARGET FUND INTO 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 Merger. More complete information is contained elsewhere in this Joint Proxy Statement/Prospectus and in the Merger SAI and the appendices hereto and thereto. Shareholders should read the entire Joint Proxy Statement/Prospectus carefully.

Background and Reasons for the Merger

Nuveen Fund Advisors, LLC (“Nuveen Fund Advisors” or the “Adviser”), a subsidiary of Nuveen, LLC and the Funds’ investment adviser, recommended the Merger proposal. Each Fund’s Board considered the Merger and determined that the Merger would be in the best interests of its Fund. Based on information provided by Nuveen Fund Advisors, the Target Fund’s Board believes that the proposed Merger may benefit the common shareholders of the Target Fund in a number of ways, including, among other things:

| • |  | The potential for higher common share net earnings and distribution levels following the Merger, due in part to the Acquiring Fund’s ability to invest to a greater degree in lower rated securities and a geographically diverse national portfolio, as well as operating economies from the combined fund’s greater scale;

| • |  | Greater secondary market liquidity and improved secondary market trading for common shares as a result of the combined fund’s greater share volume, which may lead to narrower bid-ask spreads and smaller trade-to-trade price movements;

| • |  | The potential for a narrower trading discount as a result of the Acquiring Fund’s common shares trading at a discount that, on average, has been lower over the prior twelve months from June 30, 2023 than that of the Target Fund’s common shares;

| • |  | Increased portfolio and leverage management flexibility due to the significantly larger asset base of the combined fund and the Acquiring Fund’s national mandate with greater flexibility to invest in lower rated securities; and

| • |  | Lower net operating expenses, excluding the costs of leverage, as certain fixed costs are spread over a larger asset base.

The Target Fund’s Board considered that a greater percentage of the Acquiring Fund’s portfolio may be allocated to lower rated municipal securities relative to the amount permitted by the policies of the Target Fund, and recognized that investments in lower rated securities are subject to higher risks than investments in higher rated securities. The Target Fund’s Board also noted that as a result of the Merger and the Acquiring Fund’s national mandate, it was expected that the benefit to Target Fund shareholders of any state tax exemption from investing in a state-specific municipal fund would be lost or largely unavailable.

With respect to holders of preferred shares of the Target Fund, the Target Fund’s Board considered that, upon the closing of the Merger, holders of preferred shares of the Target Fund outstanding immediately prior to the closing will receive, on a one-for-one basis, newly issued preferred shares of the Acquiring Fund having substantially similar terms to those of the preferred shares of the Target Fund immediately prior to the closing of the Merger.

Based on information provided by Nuveen Fund Advisors, the Acquiring Fund’s Board considered that the Acquiring Fund may benefit in the near-term from a modest increase in common share net earnings and operating efficiencies and over the long-term from increased investment capital, which allows the Acquiring Fund to pursue additional investment opportunities. With respect to holders of preferred shares of the Acquiring Fund, the Acquiring Fund’s Board considered that the outstanding preferred shares of the Acquiring Fund and

1

any preferred shares of the Acquiring Fund to be issued in the Merger would have equal priority with each other as to the payment of dividends and distributions of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund.

For these reasons, each Fund’s Board has determined that the Merger is in the best interest of its Fund and has approved the Merger.

For a fuller discussion of the Boards’ considerations regarding the approval of the Merger, see “C. Information About the Merger—Reasons for the Merger.”

The closing of the Merger is subject to the satisfaction or waiver of certain closing conditions, which include customary closing conditions. In order for the Merger to occur, all requisite shareholder approvals must be obtained at the applicable Fund’s shareholder Meeting, and certain other consents, confirmations and/or waivers from various third parties, including the liquidity providers and/or certain purchasers of the outstanding preferred shares of the Funds, must also be obtained. Because the closing of the Merger is contingent upon each of the Target Fund and the Acquiring Fund obtaining such shareholder approvals and satisfying (or obtaining the waiver of) other closing conditions, it is possible that the Merger will not occur, even if shareholders of a Fund entitled to vote approve the Merger proposal and a Fund satisfies all of its closing conditions, if the other Fund does not obtain its requisite shareholder approvals or satisfy (or obtain the waiver of) its closing conditions. If the Merger is not consummated, the Board of the Target Fund may take such actions as it deems in the best interests of the Target Fund, including conducting additional solicitations with respect to the Merger proposal or continuing to operate the Target Fund as a standalone fund.

The Funds believe that their respective preferred shares are held by a small number of 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, the approval by a Fund’s preferred shareholders required for the Merger to occur may turn on the exercise of voting or consent rights by such particular shareholder(s) and its or their determination as to the favorable view of the Merger with respect to its or their interests. The Funds exercise no influence or control over the determinations of such shareholders with respect to the Merger proposal; there is no guarantee that such shareholders will approve the proposal over which they may exercise effective disposition power. If the Merger is not consummated, each Fund’s Board may take such actions as it deems in the best interests of its Fund, including conducting additional solicitations with respect to the proposal or, with respect to the Target Fund’s Board, continuing to operate the Target Fund as a standalone fund.

Material Federal Income Tax Consequences of the Merger

As a non-waivable condition to closing, each Fund will receive an opinion of Vedder Price P.C., subject to certain representations, assumptions and conditions, substantially to the effect that the proposed Merger will qualify as a “reorganization” under Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). Accordingly, it is expected that neither Fund will generally recognize gain or loss for federal income tax purposes as a direct result of the Merger. It is also expected that shareholders of the Target Fund who receive Acquiring Fund shares pursuant to the Merger will recognize no gain or loss for federal income tax purposes as a result of such exchange, except to the extent a common shareholder of the Target Fund receives cash in lieu of a fractional Acquiring Fund common share. Prior to the closing of the Merger, the Target Fund expects to declare a distribution to common shareholders of all of its undistributed net investment income and net capital gains, if any. All or a portion of such a distribution may be taxable to the Target Fund’s common shareholders for federal income tax purposes. In addition, to the extent that portfolio securities of the Target Fund are sold prior to the closing of the Merger, the Target Fund may recognize gains or losses, which may increase or decrease the net capital gains or net investment income to be distributed by the Target Fund. If the Merger had occurred as of June 30, 2023, it is estimated that approximately 59% of the Target Fund’s investment portfolio would have been

2

sold by the Acquiring Fund following the Merger. To the extent the Acquiring Fund sells securities following the Merger, the Acquiring Fund may recognize gains (including any built-in gain in the portfolio investments of the Target Fund that was unrealized at the time of the Merger), which may result in taxable distributions to Acquiring Fund shareholders (including former shareholders of the Target Fund who hold shares of the Acquiring Fund following the Merger). If such repositioning had been completed as of June 30, 2023, the repositioning would not have generated net capital gain, taking into account capital loss carryforwards (as calculated without regard to possible limitations on the use of capital loss carryforwards that may result from the Merger). Following the Merger, the Acquiring Fund’s ability to use capital loss carryforwards may be limited. Securities held by the Funds are purchased and sold on a principal rather than agency basis, and such transactions are not subject to separate brokerage commissions.

The foregoing discussion and the tax opinion discussed above to be received by the Funds regarding certain aspects of the Merger, including that the Merger will qualify as a reorganization under Section 368(a) of the Code, will rely on the position that the Acquiring Fund preferred shares to be issued in the Merger, if any, will constitute equity of the Acquiring Fund for federal income tax purposes. See “C. Information About the Merger—Material Federal Income Tax Consequences of the Merger.”

Comparison of the Acquiring Fund and the Target Fund

General. The Acquiring Fund and the Target Fund are diversified, closed-end management investment companies organized as Massachusetts business trusts. Set forth below is certain comparative information about the organization, capitalization and operation of the Funds.

Fund |  | Organization Date |  | State of Organization |  |  | Entity Type |
Target Fund |  | January 12, 1993 |  |  | Commonwealth of Massachusetts |  |  |  | Business Trust |
Acquiring Fund |  | July 29, 2002 |  |  | Commonwealth of Massachusetts |  |  |  | Business Trust |

Capitalization—Common Shares(1) |
Fund |  | Authorized Shares |  |  | Shares Outstanding(1) |  | Par Value Per Share |  |  | Preemptive, Conversion or Exchange Rights |  |  | Rights to Cumulative Voting |  |  | Exchange on which Common Shares are Listed |

(1) | As of July 31, 2023.

The Funds currently have outstanding the following series of preferred shares, with the Acquiring Fund’s MFP Shares, VRDP Shares and AMTP Shares expected to remain outstanding following the completion of the Merger:

Target Fund—Preferred Shares |
Series |  | Shares Outstanding |  |  | Par Value Per Share |  |  | Liquidation Preference Per Share |
Series 1 VRDP Shares |  |  | 740 |  |  | $ | 0.01 |  |  | $ | 100,000 |

3

Acquiring Fund—Preferred Shares |
Series |  | Shares Outstanding |  |  | Par Value Per Share |  |  | Liquidation Preference Per Share |
Series 2028-1 AMTP Shares |  |  | 1,730 |  |  | $ | 0.01 |  |  | $ | 100,000 |
Series A MFP Shares |  |  | 1,350 |  |  | $ | 0.01 |  |  | $ | 100,000 |
Series B MFP Shares |  |  | 3,350 |  |  | $ | 0.01 |  |  | $ | 100,000 |
Series C MFP Shares |  |  | 2,380 |  |  | $ | 0.01 |  |  | $ | 100,000 |
Series D MFP Shares |  |  | 330,900 |  |  | $ | 0.01 |  |  | $ | 1,000 |
Series 1 VRDP Shares |  |  | 2,190 |  |  | $ | 0.01 |  |  | $ | 100,000 |
Series 3 VRDP Shares |  |  | 3,509 |  |  | $ | 0.01 |  |  | $ | 100,000 |
Series 4 VRDP Shares |  |  | 4,895 |  |  | $ | 0.01 |  |  | $ | 100,000 |
Series 5 VRDP Shares |  |  | 1,000 |  |  | $ | 0.01 |  |  | $ | 100,000 |

Each Fund’s preferred shares are entitled to one vote per share. The VRDP Shares of the Acquiring Fund to be issued in connection with the Merger, if any, 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 upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund. In addition, the preferred shares of the Acquiring Fund, including any preferred shares of the Acquiring Fund to be issued in connection with the Merger, will be senior in priority to the Acquiring Fund’s common shares as to payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund. Any preferred shares of the Acquiring Fund to be issued in connection with the Merger will have rights and preferences, including liquidation preferences, that are substantially similar to those of the Target Fund’s preferred shares immediately prior to the closing of the Merger. The number of preferred shares currently outstanding may change due to market or other conditions.

Investment Objectives and Policies. The Funds have similar investment objectives, policies and risks, but there are differences. The Target Fund is a state-specific municipal fund that seeks to provide current income exempt from regular federal income tax and the income tax of a single state. In contrast, the Acquiring Fund is a national municipal fund that seeks to provide current income exempt from regular federal income tax and the federal alternative minimum tax applicable to individuals. Because the Target Fund invests primarily in Massachusetts municipal obligations, it is subject to economic, political and other risks of a single state, while the Acquiring Fund, which may invest in municipal securities of any U.S. state or territory, is not subject to similar single state risk.

The Target Fund’s primary investment objective is to provide, through investment in a professionally managed portfolio of tax-exempt municipal obligations, current income exempt from both regular federal income taxes and Massachusetts personal income taxes, consistent with the Fund’s investment policies. The secondary investment objective of the Target Fund is the enhancement of portfolio value relative to the Massachusetts municipal bond market through investments in tax-exempt Massachusetts municipal obligations that, in the opinion of the Adviser, are underrated or undervalued or that represent municipal market sectors that are undervalued.

The Acquiring Fund’s investment objectives are to provide current income exempt from regular federal income tax and the federal alternative minimum tax applicable to individuals, and to enhance portfolio value relative to the municipal bond market by investing in tax-exempt municipal securities that the Adviser believes are underrated or undervalued or that represent municipal market sectors that are undervalued.

The Target Fund invests primarily in investment grade securities, while the Acquiring Fund is permitted to allocate a greater percentage of its portfolio to lower rated municipal securities. Investments in lower rated securities are subject to higher risks than investments in higher rated securities, including a higher risk that the issuer will be unable to pay interest or principal when due.

4

Each Fund is a diversified, closed-end management investment company and currently employs leverage through the issuance of preferred shares and the use of inverse floating rate securities.

The following summary compares the current principal investment policies and strategies of the Acquiring Fund to the current principal investment policies and strategies of the Target Fund as of the date of this Joint Proxy Statement/Prospectus.

(1) | Each Fund defines “Assets” as the net assets of the Fund plus the amount of any borrowings for investment purposes.

(2) | Each Fund defines “Managed Assets” as the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of generally accepted accounting principles), and derivatives will be valued at their market value.

During temporary defensive periods (e.g., times when, in the Target Fund’s investment adviser’s and/or the Target Fund’s sub-adviser’s opinion, temporary imbalances of supply and demand or other temporary dislocations in the tax-exempt bond market adversely affect the price at which long-term or intermediate-term municipal securities are available), the Target Fund may invest up to 100% of its net assets in cash or cash equivalents, short-term investments or municipal bonds and deviate from its investment policies including the Target Fund’s 80% names rule policy. Also, during these periods the Target Fund may not achieve its investment objectives.

During temporary defensive periods or in order to help keep the Acquiring Fund’s assets fully invested, including during the period within which the net proceeds of an offering of securities are first being invested, the Acquiring Fund may deviate from its investment policies and objectives. During such periods, the Acquiring Fund may invest any percentage of its Managed Assets in short-term investments, including high quality, short-term debt securities that may be either tax-exempt or taxable. The Acquiring Fund may not achieve its investment objectives during such periods.

Credit Quality. A comparison of the credit quality(1) (as a percentage of total investment exposure, which includes the leveraged effect of the Funds’ investments in inverse floating rate securities of tender option bond trusts) of the portfolios of the Target Fund and the Acquiring Fund, as of July 31, 2023, is set forth below.

Credit ratings are subject to change. AAA, AA, A, and BBB are investment-grade ratings; BB or lower are below investment-grade ratings. Certain bonds backed by U.S. government or agency securities are regarded as having an implied rating equal to the rating of such securities.

Credit ratings are subject to change. AAA, AA, A, and BBB are investment-grade ratings; BB or lower are below investment-grade ratings. Certain bonds backed by U.S. government or agency securities are regarded as having an implied rating equal to the rating of such securities. Holdings designated N/R are not rated by these national rating agencies.

State Allocation. A comparison of the state allocation (as a percentage of total investment exposure, which includes the leveraged effect of the Funds’ investments in inverse floating rate securities of tender option bond trusts) of the portfolios of the Acquiring Fund and the Target Fund, as of July 31, 2023, is set forth below.

Leverage. Each Fund may utilize the following forms of leverage: the issuance of preferred shares and portfolio investments that have the economic effect of leverage, including inverse floating rate securities (sometimes referred to as “inverse floaters”). The Acquiring Fund may also enter into reverse repurchase agreements (effectively a secured borrowing) and borrowings (subject to certain investment restrictions). As a fundamental policy, the Acquiring Fund may not issue senior securities, other than preferred shares, except to the extent permitted under the 1940 Act and except as otherwise described in this Joint Proxy Statement/Prospectus. As a fundamental policy, the Target Fund may not issue senior securities, as defined in the 1940 Act, other than preferred shares. Additionally, as a fundamental policy, neither the Acquiring Fund nor the Target Fund may borrow money, except from banks for temporary or emergency purposes, or to repurchase its shares, and then only in an amount not exceeding one-third of the value of the Fund’s total assets including the amount borrowed. Each Fund currently employs leverage through the issuance of preferred shares and the use of inverse floaters. In addition, each Fund may use derivatives and other portfolio instruments that have the economic effect of leverage by creating additional investment exposure. Certain important ratios related to each Fund’s use of leverage for the last three fiscal years for which published financial statements are available are set forth below:

Target Fund |  | 2023 |  |  | 2022 |  |  | 2021 |
Asset Coverage Ratio(1) |  |  | 252.78 | % |  |  | 262.69 | % |  |  | 293.57 | %
Regulatory Leverage Ratio(2) |  |  | 39.56 | % |  |  | 38.07 | % |  |  | 34.06 | %
Effective Leverage Ratio(3) |  |  | 41.84 | % |  |  | 40.32 | % |  |  | 36.21 | %

Acquiring Fund |  | 2022 |  |  | 2021 |  |  | 2020 |
Asset Coverage Ratio(1) |  |  | 241.94 | % |  |  | 283.15 | % |  |  | 280.55 | %
Regulatory Leverage Ratio(2) |  |  | 41.33 | % |  |  | 35.32 | % |  |  | 35.64 | %
Effective Leverage Ratio(3) |  |  | 43.07 | % |  |  | 37.35 | % |  |  | 37.54 | %

(1) | A Fund’s asset coverage ratio is defined under the 1940 Act as the ratio that the value of the total assets of the Fund, less all liabilities and indebtedness not represented by preferred shares or senior securities representing indebtedness, bears to the aggregate amount of preferred shares and senior securities representing indebtedness issued by the Fund.

(2) | Regulatory leverage consists of preferred shares issued by or borrowings (if applicable) of a Fund. Both of these are part of a Fund’s capital structure. A Fund, however, may from time to time borrow on a typically transient basis in connection with its day-to-day operations, primarily in connection with the need to settle portfolio trades. Such incidental borrowings are excluded from the calculation of a Fund’s regulatory leverage and effective leverage ratios. Regulatory leverage is subject to asset coverage limits set forth in the 1940 Act.

9

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

Board Members and Officers. The Acquiring Fund and the Target Fund have the same Board Members and officers. The management of each Fund, including general oversight of the duties performed by the Fund’s investment adviser under an investment management agreement between the investment adviser and such Fund (each, an “Investment Management Agreement”), is the responsibility of its Board. Each Fund currently has ten (10) Board Members, each of whom is not considered an “interested person,” as defined in the 1940 Act.

Pursuant to each Fund’s by-laws, the Board of the 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; provided, however, that holders of preferred shares are entitled as a class to elect two Board Members at all times. The staggered board structure could delay for up to two years the election of a majority of the Board of each Fund. To the extent that one or more preferred shareholders owns, holds or controls, individually or in aggregate, all or a significant portion of a series of a Fund’s outstanding preferred shares, a few holders could exert influence on the selection of the Board as a result of the requirement that holders of preferred shares be entitled to elect two Board Members at all times. The Acquiring Fund’s board structure will remain in place following the closing of the Merger.

Investment Adviser. Nuveen Fund Advisors, LLC (previously defined as “Nuveen Fund Advisors” or the “Adviser”) is the investment adviser to each Fund and is responsible for overseeing each Fund’s overall investment strategy, including the use of leverage, and its implementation. Nuveen Fund Advisors also is responsible for the ongoing monitoring of any sub-adviser to the Funds, managing each Fund’s business affairs and providing certain clerical, bookkeeping and other administrative services to the Funds. Nuveen Fund Advisors is located at 333 West Wacker Drive, Chicago, Illinois 60606.

Nuveen Fund Advisors, a registered investment adviser, is a subsidiary of Nuveen, LLC (“Nuveen”), the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). TIAA is a life insurance company founded in 1918 by the Carnegie Foundation for the Advancement of Teaching and is the companion organization of College Retirement Equities Fund. As of June 30, 2023, Nuveen managed approximately $1.2 trillion in assets, of which approximately $140.9 billion was managed by Nuveen Fund Advisors.

Unless earlier terminated as described below, each Fund’s Investment Management Agreement with Nuveen Fund Advisors will remain in effect until August 1, 2024. Each Investment 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 the Fund; and (2) a majority of the Board Members who are not interested persons of any party to the Investment Management Agreement, cast in person at a meeting called for the purpose of voting on such approval. Each Investment Management Agreement may be terminated at any time, without penalty, by either the Fund or Nuveen Fund Advisors upon 60 days’ written notice and is automatically terminated in the event of its assignment, as defined in the 1940 Act.

Pursuant to each Investment Management Agreement, each Fund has agreed to pay an annual management fee for the overall advisory and administrative services and general office facilities provided by Nuveen Fund Advisors. Each Fund’s management fee consists of two components—a complex-level fee, based on the aggregate amount of all eligible fund assets of Nuveen-branded closed- and open-end registered investment companies organized in the United States, and a specific fund-level fee, based only on the amount of assets of such Fund. This 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.

10

For the Target Fund’s fiscal year ended May 31, 2023, the effective management fee rate of the Target Fund, expressed as a percentage of average total daily managed assets (including assets attributable to leverage), was 0.60%. For the Acquiring Fund’s six-month semi-annual period ended April 30, 2023, the effective management fee rate of the Acquiring Fund, expressed as a percentage of average total daily managed assets (including assets attributable to leverage), was 0.54%.

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

Current Fund-Level Fee Schedule for the Funds

Average Total Daily Managed Assets* |  | Annual 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 |  |  | 0.3750 | %
For managed assets over $5 billion |  |  | 0.3625 | %

* | For this purpose, managed assets means the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of effective leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of U.S. generally accepted accounting principles).

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, listing fees and taxes, if any.

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-branded closed- and open-end registered investment companies organized in the United States, as stated in the table below. As of July 31, 2023, the complex-level fee rate for each Fund was 0.1594%.

11

The annual complex-level fee for each Fund, payable monthly, is calculated by multiplying the current complex-wide fee rate, determined according to the following schedule by a Fund’s daily managed assets:

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 complex-level fees, managed assets include closed-end fund assets managed by the Adviser that are attributable to certain types of leverage. For these purposes, leverage includes the funds’ use of preferred shares 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 open-end and closed-end 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 the Adviser’s assumption of the management of the former First American Funds effective January 1, 2011, but do include certain assets of certain Nuveen funds that were reorganized into funds advised by an affiliate of the Adviser during the 2019 calendar year.

Sub-Adviser. Nuveen Fund Advisors has selected its wholly owned subsidiary, Nuveen Asset Management, LLC (“Nuveen Asset Management” or the “Sub-Adviser”), located at 333 West Wacker Drive, Chicago, Illinois 60606, to serve as the sub-adviser to each of the Funds pursuant to a sub-advisory agreement between Nuveen Fund Advisors and Nuveen Asset Management (the “Sub-Advisory Agreement”). Nuveen Asset Management, a registered investment adviser, oversees day-to-day operations and manages the investment of the Funds’ assets on a discretionary basis, subject to the supervision of Nuveen Fund Advisors. Pursuant to each Sub-Advisory Agreement, Nuveen Asset Management is compensated for the services it provides to the Funds with a portion of the management fee Nuveen Fund Advisors receives from each Fund. Nuveen Fund Advisors and Nuveen Asset Management retain the right to reallocate investment advisory responsibilities and fees between themselves in the future.

For the services provided pursuant to the Target Fund’s and the Acquiring Fund’s Sub-Advisory Agreements, Nuveen Fund Advisors pays Nuveen Asset Management a portfolio management fee, 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.

A discussion of the basis for the Board’s most recent approval of the current Investment Management Agreement and Sub-Advisory Agreement for the Target Fund was included in the Target Fund’s Annual Report for the fiscal year ended May 31, 2023. A discussion of the basis for the Board’s most recent approval of the current Investment Management Agreement and Sub-Advisory Agreement for the Acquiring Fund will be included in the Acquiring Fund’s Annual Report for the fiscal year ending October 31, 2023.

12

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 operations. Nuveen Asset Management manages the portfolio of each Fund using a team of analysts and a portfolio manager that focuses on a specific group of funds. Christopher L. Drahn, CFA, is the portfolio manager of the Acquiring Fund and Michael S. Hamilton is the portfolio manager of the Target Fund. Additional information regarding the portfolio managers’ compensation, other accounts managed and ownership of securities is contained in the Merger SAI. Mr. Drahn assumed portfolio management responsibility for the Acquiring Fund in 2016, and Mr. Hamilton assumed portfolio management responsibility for the Target Fund in 2011. The portfolio management team of the Acquiring Fund will manage the combined fund upon completion of the Merger.

Christopher L. Drahn, CFA, is a Managing Director of Nuveen Asset Management. He is a portfolio manager responsible for managing a number of Nuveen’s tax-exempt fixed income portfolios as well as mutual funds and closed-end funds.

Comparative Risk Information

Risk is inherent in all investing. Investing in the Funds involves risk, including the risk that you may receive little or no return on your investment or that you may even lose part or all of your investment. An investment in the Funds is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Before you invest in a Fund, you should consider its principal risks.

Because each Fund invests primarily in municipal securities and other investments the income from which is exempt from regular federal income tax, the principal risks of an investment in each Fund are similar. However, there are differences between the Funds’ investment policies that may affect their comparative risk profiles. The Target Fund is subject to single-state risk, while the Acquiring Fund is not. Due to differences between the Target Fund’s policies on credit quality and those of the Acquiring Fund, an investment in the Acquiring Fund may be subject to credit risk and below investment grade risk to a greater degree than an investment in the Target Fund.

The principal risks of investing in the Acquiring Fund are described in more detail below. See “B. Risk Factors” at page [●].

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 of the Target Fund for the fiscal year ended May 31, 2023, the Acquiring Fund for the semi-annual period ended April 30, 2023 (annualized) and the pro forma fees and expenses of the combined fund following the Merger for the six-month period ended April 30, 2023 (annualized). The assets of the Funds will vary based on market conditions and other factors and may vary significantly during volatile market conditions.

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.

Total Annual Expenses |  |  | 3.19 | % |  |  | 3.44 | % |  |  | 3.44 | %

(1) | The table presented above estimates what the annual expenses of the combined fund following the Merger would be stated as a percentage of the combined fund’s net assets attributable to common shares including the costs of leverage for the six month semi-annual period ended April 30, 2023 (annualized). Please see “Additional Information About the Acquiring Fund—Annual Expenses Excluding the Costs of Leverage” at page [●] for additional information.

(2) | Assumes the issuance of preferred shares in the amounts set forth in the capitalization table. Such amounts may change prior to the Closing Date. Please see “C. Information About the Merger — Capitalization” at page [●].

(3) | Fees on preferred shares assume annual dividends paid, annual remarketing fees, where applicable, and amortization of offering costs, and annual liquidity fees, where applicable. Interest and Related Expenses from Inverse Floaters include interest expense attributable to inverse floating rate securities regardless of how such securities are treated for financial statement purposes. The actual fees on preferred shares and interest and related expenses from inverse floaters incurred in the future may be higher or lower. If short-term market interest rates rise in the future, and if the Funds continue to maintain leverage at similar levels, the cost of which is tied to short-term interest rates, the Funds’ interest expense can be expected to rise in tandem. The Funds’ use of leverage will increase the amount of management fees paid to the Adviser and Sub-Adviser.

(4) | Other Expenses are estimated based on actual expenses from the prior fiscal year.

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.

Comparative Performance Information

Comparative total return performance for the Funds for periods ended July 31, 2023:

|  | Average Annual Total Return on Net Asset Value |  |  | Average Annual Total Return on Market Value |
|  | One Year |  |  | Five Years |  |  | Ten Years |  |  | One Year |  |  | Five Years |  |  | Ten Years |
Target Fund |  |  | -2.71 | % |  |  | 0.48 | % |  |  | 2.72 | % |  |  | -10.79 | % |  |  | 0.49 | % |  |  | 1.62 | %
Acquiring Fund |  |  | -2.37 | % |  |  | 1.26 | % |  |  | 4.10 | % |  |  | -10.24 | % |  |  | 1.23 | % |  |  | 4.18 | %

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),

14

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. Past performance information is not necessarily indicative of future results.

B. | RISK FACTORS

An 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 Acquiring 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 shares of 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.

The principal risks of investing in the Acquiring Fund are described below. The risks and special considerations listed below should be considered by common shareholders of the Target Fund in their evaluation of the Merger. While investment in the Target Fund is also generally subject to each of these principal risks, the shareholders of the Target Fund should also consider the following differences between the Funds’ investment policies that may affect the comparative risk profile: (i) the Acquiring Fund may invest in municipal obligations of any U.S. state or territory, whereas the Target Fund invests primarily in municipal bonds of a single state and is subject to economic, political and other risks of a single state, and (ii) a greater percentage of the Acquiring Fund’s portfolio may be allocated to lower rated municipal securities relative to the amount permitted by the policies of the Target Fund, and investments in lower rated securities are subject to higher risks than investments in higher rated securities, including a higher risk that the issuer will be unable to pay interest or principal when due.

General Risks of Investing in the Acquiring Fund

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

Market Discount from Net Asset Value. The market price of shares of closed-end investment companies may fluctuate and during certain periods trade at prices lower than net asset value. The Fund cannot predict whether its common shares will trade at, above or below net asset value. This characteristic is a risk separate and distinct from the risk that the 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 the Fund as a vehicle for trading purposes.

Credit Risk. Credit risk is the risk that one or more municipal securities in the Fund’s portfolio will decline in price, or the issuer thereof will fail to pay interest or principal when due, because the issuer of the security experiences a decline in its financial status. In general, lower-rated municipal securities carry a greater

15

degree of risk that the issuer will lose its ability to make interest and principal payments, which could have a negative impact on the Fund’s net asset value or dividends. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates. If a municipal security satisfies the rating requirements described above at the time of investment and is subsequently downgraded below that rating, the Fund will not be required to dispose of the security. If a downgrade occurs, the Sub-Adviser will consider what action, including the sale of the security, is in the best interests of the Fund and its shareholders. This means that the Fund may invest in municipal securities that are involved in bankruptcy or insolvency proceedings or are experiencing other financial difficulties at the time of acquisition (such securities are commonly referred to as distressed securities).

Credit Spread Risk. Credit spread risk is the risk that credit spreads (i.e., the difference in yield between securities that is due to differences in their credit quality) may increase when the market believes that municipal securities generally have a greater risk of default. Increasing credit spreads may reduce the market values of the Fund’s securities. Credit spreads often increase more for lower rated and unrated securities than for investment grade securities. In addition, when credit spreads increase, reductions in market value will generally be greater for longer-maturity securities.

Below Investment Grade Risk. Municipal securities of below investment grade quality, commonly referred to as junk bonds, are regarded as having predominately speculative characteristics with respect to capacity to pay interest and repay principal when due, and are susceptible to default or decline in market value due to adverse economic and business developments. Also, to the extent that the rating assigned to a municipal security in the 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 securities are less liquid than investment grade municipal securities. For these reasons, an investment in the Fund, compared with a portfolio consisting solely of investment grade securities, may experience the following:

| • |  | increased price sensitivity resulting from changing interest rates and/or a deteriorating economic environment;

| • |  | 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.

Adverse changes in economic conditions are more likely to lead to a weakened capacity of a below investment grade issuer to make principal payments and interest payments compared to an investment grade issuer. The principal amount of below investment grade securities outstanding has proliferated in the past decade as an increasing number of issuers have used below investment grade securities for financing. The current downturn may severely affect the ability of highly leveraged issuers to service their debt obligations or to repay their obligations upon maturity. As the national economy experiences the current economic downturn, resulting in decreased tax and other revenue streams of municipal issuers, or in the event interest rates rise sharply, increasing the interest cost on variable rate instruments and negatively impacting economic activity, the number of defaults by below investment grade municipal issuers is likely to increase. Similarly, downturns in profitability in specific industries could adversely affect private activity bonds. The market values of lower quality debt securities tend to reflect individual developments of the issuer to a greater extent than do higher quality securities, which react primarily to fluctuations in the general level of interest rates. Factors having an adverse impact on the market value of lower quality securities may have an adverse impact on the Fund’s net asset value and the market value of its common shares. In addition, the Fund may incur additional expenses to

16

the extent it is required to seek recovery upon a default in payment of principal or interest on its portfolio holdings. In certain circumstances, the Fund may be required to foreclose on an issuer’s assets and take possession of its property or operations. In such circumstances, the Fund would incur additional costs in disposing of such assets and potential liabilities from operating any business acquired.

The secondary market for below investment grade securities may not be as liquid as the secondary market for more highly rated securities, a factor that may have an adverse effect on the Fund’s ability to dispose of a particular security. There are fewer dealers in the market for below investment grade municipal securities than the market for investment grade municipal securities. The prices quoted by different dealers for below investment grade municipal securities may vary significantly, and the spread between the bid and ask price is generally much larger for below investment grade municipal securities than for higher quality instruments. Under adverse market or economic conditions, the secondary market for below investment grade securities could contract further, independent of any specific adverse changes in the condition of a particular issuer, and these instruments may become illiquid. As a result, the Fund could find it more difficult to sell these securities or may be able to sell the securities only at prices lower than if such securities were widely traded. Prices realized upon the sale of such lower rated or unrated securities, under these circumstances, may be less than the prices used in calculating the Fund’s net asset value.

Issuers of below investment grade securities are highly leveraged and may not have available to them more traditional methods of financing. Therefore, the risk associated with acquiring the securities of such issuers generally is greater than is the case with higher rated securities. For example, during an economic downturn or a sustained period of rising interest rates, highly leveraged issuers of below investment grade securities may experience financial stress. During such periods, such issuers may not have sufficient revenues to meet their interest payment obligations. The issuer’s ability to service its debt obligations also may be adversely affected by specific developments, the issuer’s inability to meet specific projected forecasts or the unavailability of additional financing. The risk of loss from default by the issuer is significantly greater for the holders of below investment grade securities because such securities are generally unsecured and are often subordinated to other creditors of the issuer. Prices and yields of below investment grade securities will fluctuate over time and, during periods of economic uncertainty, volatility of below investment grade securities may adversely affect the Fund’s net asset value. In addition, investments in below investment grade zero coupon bonds rather than income-bearing below investment grade securities may be more speculative and may be subject to greater fluctuations in value due to changes in interest rates.

Investments in lower rated or unrated securities may present special tax issues for the Fund to the extent that the issuers of these securities default on their obligations pertaining thereto, and the federal income tax consequences to the Fund as a holder of such distressed securities may not be clear.

Unrated Securities Risk. The Fund may purchase securities that are not rated by any rating organization. Unrated securities determined by the Fund’s investment adviser to be of comparable quality to rated investments which the Fund may purchase may pay a higher dividend or interest rate than such rated investments and be subject to a greater risk of illiquidity or price changes. Less public information is typically available about unrated investments or issuers than rated investments or issuers. Some unrated securities may not have an active trading market or may be difficult to value, which means the Fund might have difficulty selling them promptly at an acceptable price. To the extent that the Fund invests in unrated securities, the Fund’s ability to achieve its investment objectives will be more dependent on the investment adviser’s credit analysis than would be the case when the Fund invests in rated securities.

Municipal Securities Market Risk. Investing in the municipal securities market involves certain risks. The municipal market is one in which dealer firms make markets in bonds on a principal basis using their proprietary capital, and during the 2008-2009 market turmoil these firms’ capital was 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 the Fund’s portfolio is generally less

17

than that for corporate equities or bonds, and the investment performance of the Fund may therefore be more dependent on the analytical abilities of the Sub-Adviser than if the Fund were a stock fund or taxable bond fund. The secondary market for municipal securities, particularly the below investment grade bonds in which the Fund may invest, also tends to be less well-developed or liquid than many other securities markets, which may adversely affect the Fund’s ability to sell its municipal securities at attractive prices or at prices approximating those at which the 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. 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, the Fund could experience delays in collecting principal and interest and the 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, the Fund may take possession of and manage the assets securing the issuer’s obligations on such securities, which may increase the Fund’s operating expenses. Any income derived from the Fund’s ownership or operation of such assets may not be tax-exempt and may not be of the type that would allow the Fund to continue to qualify as a regulated investment company (“RIC”) for federal income tax purposes.

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.

Special Risks Related to Certain Municipal Obligations. The 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 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 the 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 the Fund, although the Fund does not anticipate that such a remedy would normally be pursued. To the extent that the 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, the Fund may be dependent

18

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.

Tobacco Settlement Bond Risk. Tobacco settlement bonds are municipal securities that are backed solely by expected revenues to be derived from lawsuits involving tobacco related deaths and illnesses which were settled between certain states and American tobacco companies. Tobacco settlement bonds are secured by an issuing state’s proportionate share in the Master Settlement Agreement (“MSA”). The MSA is an agreement reached out of court in November 1998 between 46 states and nearly all of the U.S. tobacco manufacturers. Under the terms of the MSA, the actual amount of future settlement payments by tobacco manufacturers is dependent on many factors, including, but not limited to, annual domestic cigarette shipments, reduced cigarette consumption, increased taxes on cigarettes, inflation, financial capability of tobacco companies, continuing litigation and the possibility of tobacco manufacturer bankruptcy. If the volume of cigarettes shipped in the U.S. by manufacturers participating in the settlement decreases significantly, payments due from them will also decrease. Demand for cigarettes in the United States could continue to decline due to price increases needed to recoup the cost of payments by tobacco companies. Demand could also be affected by anti-smoking campaigns, tax increases, reduced advertising, and enforcement of laws prohibiting sales to minors; elimination of certain sales venues such as vending machines; and the spread of local ordinances restricting smoking in public places. As a result, payments made by tobacco manufacturers could be negatively impacted if the decrease in tobacco consumption is significantly greater than the forecasted decline. A market share loss by the MSA companies to non-MSA participating tobacco manufacturers would cause a downward adjustment in the payment amounts. A participating manufacturer filing for bankruptcy also could cause delays or reductions in bond payments. The MSA itself has been subject to legal challenges and has, to date, withstood those challenges.

Zero Coupon Bonds Risk. Because interest on zero coupon bonds is not paid on a current basis, the values of zero coupon bonds will be more volatile in response to interest rate changes than the values of bonds that distribute income regularly. Although zero coupon bonds generate income for accounting purposes, they do not produce cash flow, and thus the Fund could be forced to liquidate securities at an inopportune time in order to generate cash to distribute to shareholders as required by federal income tax law to continue to qualify as a RIC.

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 the Fund’s portfolio will decline in value because of increases in market interest rates. As interest rates decline, issuers of municipal securities may prepay principal earlier than scheduled, forcing the Fund to reinvest in lower-yielding securities and potentially reducing the Fund’s income. As interest rates increase, slower than expected principal payments may extend the average life of securities, potentially locking in a below-market interest rate and reducing the Fund’s value. 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. Because the Fund will invest in long-term municipal securities, the common share net asset value and market price per share will fluctuate more in response to changes in market interest rates than if the Fund invested primarily in shorter-term municipal securities. In comparison to maturity (which is the date on which a debt instrument ceases and the issuer is obligated to repay the principal amount), duration is a measure of the price volatility of a debt instrument as a result of changes in market rates of interest, based on the weighted average timing of the instrument’s expected principal and interest payments. Duration differs from maturity in that it considers a security’s yield, coupon payments, principal payments and call features in addition to the amount of time until the security finally matures. As the value of a security changes over time, so will its duration.

Prices of securities with longer durations tend to be more sensitive to interest rate changes than securities with shorter durations. In general, a portfolio of securities with a longer duration can be expected to be more sensitive to interest rate changes than a portfolio with a shorter duration. For example, the price of a bond with an effective duration of two years will rise (fall) two percent for every one percent decrease (increase) in its yield, and the price of a five-year duration bond will rise (fall) five percent for a one percent decrease (increase) in its yield. Greater sensitivity to changes in interest rates typically corresponds to higher volatility and higher risk.

19

Yield curve risk is the risk associated with either a flattening or steepening of the yield curve, which is a result of changing yields among comparable bonds with different maturities. When market interest rates, or yields, increase, the price of a bond will decrease and vice versa. When the yield curve shifts, the price of the bond, which was initially priced based on the initial yield curve, will change in price. If the yield curve flattens, then the yield spread between long- and short-term interest rates narrows, and the price of the bond will change accordingly. If the bond is short-term and the yield decreases, the price of this bond will increase. If the yield curve steepens, this means that the spread between long- and short-term interest rates increases. Therefore, long-term bond prices, like the ones held by the Fund, will decrease relative to short-term bonds. Changes in the yield curve are based on bond risk premiums and expectations of future interest rates.

Because the values of lower-rated and comparable unrated debt securities are affected both by credit risk and interest rate risk, the price movements of such lower grade securities typically have not been highly correlated to the fluctuations of the prices of investment grade quality securities in response to changes in market interest rates. The Fund’s investments in inverse floating rate securities, as described herein under “Inverse Floating Rate Securities Risk” and “Leverage Risk,” will tend to increase common share interest rate risk.

Distressed Securities Risk. The Fund may invest to a limited extent in securities rated CCC+/Caa1 or lower, or unrated but judged by the Sub-Adviser to be of comparable quality. Some or many of these low-rated securities, although not in default, may be “distressed,” meaning that the issuer is experiencing financial difficulties or distress at the time of acquisition. Such securities would present a substantial risk of future default which may cause the Fund to incur losses, including additional expenses, to the extent it is required to seek recovery upon a default in the payment of principal or interest on those securities. In any reorganization or liquidation proceeding relating to a portfolio security, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment. Distressed securities may be subject to restrictions on resale.

Puerto Rico Municipal Securities Market Risk. To the extent that the Fund invests a significant portion of its assets in the securities issued by the Commonwealth of Puerto Rico or its political subdivisions, agencies, instrumentalities, or public corporations (collectively referred to in this prospectus as “Puerto Rico” or the “Commonwealth”), it will be disproportionally affected by political, social and economic conditions and developments in the Commonwealth. In addition, economic, political or regulatory changes in that territory could adversely affect the value of the Fund’s investment portfolio.

Puerto Rico currently is experiencing significant fiscal and economic challenges, including substantial debt service obligations, high levels of unemployment, underfunded public retirement systems, and persistent government budget deficits. These challenges may negatively affect the value of the Fund’s investments in Puerto Rican municipal securities. Major ratings agencies have downgraded the general obligation debt of Puerto Rico to below investment grade and continue to maintain a negative outlook for this debt, which increases the likelihood that the rating will be lowered further. In both August 2015 and January 2016, Puerto Rico defaulted on its debt by failing to make full payment due on its outstanding bonds, and there can be no assurance that Puerto Rico will be able to satisfy its future debt obligations. Further downgrades or defaults may place additional strain on the Puerto Rico economy and may negatively affect the value, liquidity, and volatility of the Fund’s investments in Puerto Rican municipal securities. Legislation, including legislation that would allow Puerto Rico to restructure its municipal debt obligations, thus increasing the risk that Puerto Rico may never pay off municipal indebtedness, or may pay only a small fraction of the amount owed, could also impact the value of the Fund’s investments in Puerto Rican municipal securities.

These challenges and uncertainties have been exacerbated by Hurricane Maria and the resulting natural disaster in Puerto Rico. In September 2017, Hurricane Maria struck Puerto Rico, causing major damage across the Commonwealth, including damage to its water, power, and telecommunications infrastructure. The length of time needed to rebuild Puerto Rico’s infrastructure is unclear, but could amount to years, during which the Commonwealth is likely to be in an uncertain economic state. The full extent of the natural disaster’s impact on Puerto Rico’s economy and foreign investment in Puerto Rico is difficult to estimate.

20

Puerto Rico’s political and economic conditions could have a negative impact on the liquidity or value of Puerto Rican municipal securities, and consequently may affect the Fund’s investments and its performance if the Fund invests a significant portion of its assets in Puerto Rican municipal securities.

Economic and Political Events Risk. The Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of similar projects (such as those relating to the education, health care, housing, transportation, or utilities industries), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds or moral obligation bonds). Such developments may adversely affect a specific industry or local political and economic conditions, and thus may lead to declines in the bonds’ creditworthiness and value.

Global Economic Risk. National and regional economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country, region or market might adversely impact issuers in a different country, region or market. Changes in legal, political, regulatory, tax and economic conditions may cause fluctuations in markets and investments prices around the world, which could negatively impact the value of the Fund’s investments. Major economic or political disruptions, particularly in large economies like China’s, may have global negative economic and market repercussions. Additionally, instability in various countries, such as Afghanistan and Syria, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies, possible terrorist attacks in the United States and around the world, continued tensions between North Korea and the United States and the international community generally, growing social and political discord in the United States, the European debt crisis, the response of the international community—through economic sanctions and otherwise—further downgrade of U.S. government securities, the change in the U.S. president and the new administration and other similar events may adversely affect the global economy and the markets and issuers in which the Fund invests. Recent examples of such events include the outbreak of a novel coronavirus known as COVID-19 that was first detected in China in December 2019 and heightened concerns regarding North Korea’s nuclear weapons and long-range ballistic missile programs. In addition, Russia’s recent invasion of Ukraine in February 2022 has resulted in sanctions imposed by several nations, such as the United States, United Kingdom, European Union and Canada. The current sanctions and potential further sanctions may negatively impact certain sectors of Russia’s economy, but also may negatively impact the value of the Fund’s investments that do not have direct exposure to Russia. These events could reduce consumer demand or economic output, result in market closure, travel restrictions or quarantines, and generally have a significant impact on the economy. These events could also impair the information technology and other operational systems upon which the Fund’s service providers, including the Adviser and the Sub-Adviser, rely, and could otherwise disrupt the ability of employees of the Fund’s service providers to perform essential tasks on behalf of the Fund.

The Fund does not know and cannot predict how long the securities markets may be affected by these events and the effects of these and similar events in the future on the U.S. economy and securities markets. The Fund may be adversely affected by abrogation of international agreements and national laws which have created the market instruments in which the Fund may invest, failure of the designated national and international authorities to enforce compliance with the same laws and agreements, failure of local, national and international organizations to carry out the duties prescribed to them under the relevant agreements, revisions of these laws and agreements which dilute their effectiveness or conflicting interpretation of provisions of the same laws and agreements.

Governmental and quasi-governmental authorities and regulators throughout the world have in the past responded to major economic disruptions with a variety of significant fiscal and monetary policy changes, including but not limited to, direct capital infusions into companies, new monetary programs and dramatically lower interest rates. An unexpected or quick reversal of these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which could adversely affect the Fund’s investments. See “—Recent Market Conditions” below.

21

Recent Market Conditions. Periods of unusually high financial market volatility and restrictive credit conditions, at times limited to a particular sector or geographic area, have occurred in the past and may be expected to recur in the future. Some countries, including the United States, have adopted or have signaled protectionist trade measures, relaxation of the financial industry regulations that followed the financial crisis, and/or reductions to corporate taxes. The scope of these policy changes is still developing, but the equity and debt markets may react strongly to expectations of change, which could increase volatility, particularly if a resulting policy runs counter to the market’s expectations. The outcome of such changes cannot be foreseen at the present time. In addition, geopolitical and other risks, including environmental and public health risks, may add to instability in the world economy and markets generally. As a result of increasingly interconnected global economies and financial markets, the value and liquidity of the Fund’s investments may be negatively affected by events impacting a country or region, regardless of whether the Fund invests in issuers located in or with significant exposure to such country or region.

Ukraine has experienced ongoing military conflict, most recently in February 2022 when Russia invaded Ukraine; this conflict may expand and military attacks could occur elsewhere in Europe. Europe has also been struggling with mass migration from the Middle East and Africa. The ultimate effects of these events and other socio-political or geographical issues are not known but could profoundly affect global economies and markets.

The ongoing trade war between China and the United States, including the imposition of tariffs by each country on the other country’s products, has created a tense political environment. These actions may trigger a significant reduction in international trade, the oversupply of certain manufactured goods, substantial price reductions of goods and possible failure of individual companies and/or large segments of China’s export industry, which could have a negative impact on the Fund’s performance. U.S. companies that source material and goods from China and those that make large amounts of sales in China would be particularly vulnerable to an escalation of trade tensions. Uncertainty regarding the outcome of the trade tensions and the potential for a trade war could cause the U.S. dollar to decline against safe haven currencies, such as the Japanese yen and the euro. Events such as these and their consequences are difficult to predict and it is unclear whether further tariffs may be imposed or other escalating actions may be taken in the future.

Recently the U.S. Federal Reserve (the “Fed”) has sharply raised interest rates and has signaled an intention to continue to do so until current inflation levels re-align with the Fed’s long-term inflation target. Changing interest rate environments impact the various sectors of the economy in different ways. For example, in March 2023, the Federal Deposit Insurance Corporation (“FDIC”) was appointed receiver for each of Silicon Valley Bank and Signature Bank, the second- and third-largest bank failures in U.S. history, which failures may be attributable, in part, to rising interest rates. Bank failures may have a destabilizing impact on the broader banking industry or markets generally.

The impact of these developments in the near- and long-term is unknown and could have additional adverse effects on economies, financial markets and asset valuations around the world.

Inverse Floating Rate Securities Risk. The Fund may invest in inverse floating rate securities. Typically, inverse floating rate securities represent beneficial interests in a special purpose trust (sometimes called a “tender option bond trust”) formed by a third party sponsor for the purpose of holding municipal bonds. In general, income on inverse floating rate securities will decrease when interest rates increase and increase when interest rates decrease. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal rates fall. Inverse floating rate securities generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment. Investments in inverse floating rate securities may subject the Fund to the risks of reduced or eliminated interest payments and losses of principal.

The Fund may invest in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund. In the Adviser and/or the Sub-Adviser’s discretion, the Fund may enter into a separate shortfall and

22

forbearance agreement with the third party sponsor of a special purpose trust. The 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 the Fund to reimburse the third party sponsor of the trust, 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. In such instances, the Fund may be at risk of loss that exceeds its investment in the inverse floating rate securities.

Because of the leveraged nature of such investments, inverse floating rate securities may increase or decrease in value at a greater rate than the underlying fixed rate municipal bonds held by the tender option bond. As a result, the market value of such securities generally is more volatile than that of fixed rate securities.

The Fund’s investments in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund may be highly leveraged. The structure and degree to which the Fund’s inverse floating rate securities are highly leveraged will vary based upon a number of factors, including the size of the trust itself and the terms of the underlying municipal security. An inverse floating rate security generally is considered highly leveraged if the principal amount of the short-term floating rate interests issued by the related special purpose trust has a three to one gearing to the principal amount of the inverse floating rate securities owned by the trust. In the event of a significant decline in the value of an underlying security, the Fund may suffer losses in excess of the amount of its investment (up to an amount equal to the value of the municipal securities underlying the inverse floating rate securities) as a result of liquidating special purpose trusts or other collateral in connection with managing the overall economic effect of leverage on the Fund.

The economic effect of leverage created through the Fund’s investments in inverse floating rate securities will create an opportunity for increased common share net income and returns, but will also create the possibility that common share long-term returns will be diminished if the cost of leverage exceeds the return on the inverse floating rate securities purchased by the Fund.

Inverse floating rate securities have varying degrees of liquidity based, among other things, upon the liquidity of the underlying securities deposited in a special purpose trust. The market price of inverse floating rate securities is more volatile than the underlying securities due to leverage. 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 certain circumstances, the likelihood of an increase in the volatility of net asset value and market price of the common shares may be greater for a fund (like the Fund) that relies primarily on inverse floating rate securities to achieve the economic effect of leverage. The Fund may be required to sell its inverse floating rate securities at less than favorable prices, or liquidate other Fund portfolio holdings in certain circumstances, including, but not limited to, the following:

| • |  | If the Fund has a need for cash and the securities 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 security 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.

The amount of fees paid to the Adviser (which in turn pays a portion of its fees to the Sub-Adviser) for investment advisory services will be higher if the Fund uses leverage because the fees will be calculated based on the Fund’s net assets—this may create an incentive for the Adviser and/or the Sub-Adviser to leverage the Fund.

23

There is no assurance that the Fund’s strategy of investing in inverse floating rate securities will be successful.

Leverage Risk. The use of leverage creates special risks for common shareholders, including the likelihood of greater volatility of net asset value and market price of, and distributions on, the common shares than a comparable portfolio without leverage. The use of leverage in a declining market will likely cause a greater decline in common share net asset value, which may result in a greater decline of the common share price, than if the Fund were not to have used leverage.

Leverage risk is the risk associated with the use of the Fund’s outstanding preferred shares, use of tender option bonds or borrowings, if any, to leverage the common shares. There can be no assurance that the Fund’s leveraging strategy will be successful. Because the long-term municipal securities in which the Fund invests generally pay fixed rates of interest while the Fund’s costs of leverage generally fluctuate with short- to intermediate-term yields, the incremental earnings from leverage will vary over time. However, the Fund may use derivatives, such as interest rate swaps, to fix the effective rate paid on all or a portion of the Fund’s leverage in an effort to lower leverage costs over an extended period. Accordingly, the Fund cannot assure you that the use of leverage will result in a higher yield or return to common shareholders. The income benefit from leverage will be reduced to the extent that the difference narrows between the net earnings on the Fund’s portfolio securities and its cost of leverage. The income benefit from leverage will increase to the extent that the difference widens between the net earnings on the Fund’s portfolio securities and its cost of leverage. If short- or intermediate-term rates rise, the Fund’s cost of leverage could exceed the fixed 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. This could occur even if short- or intermediate-term and long-term municipal rates rise.

The Fund will pay (and common shareholders will bear) any costs and expenses relating to the Fund’s use of leverage, which will result in a reduction in the net asset value of and net income payable with respect to the common shares. Because of the costs of leverage, the Fund may incur losses even if the Fund has positive returns if they are not sufficient to cover the costs of leverage. The Adviser, based on its assessment of market conditions, may increase or decrease the Fund’s level of leverage. Such changes may impact the Fund’s distributions and the valuation of the common shares in the secondary market. There is no assurance that the Fund will continue to utilize leverage or that the Fund’s use of leverage will be successful. Furthermore, the amount of fees paid to the Adviser and the Sub-Adviser for investment advisory services will be higher if the Fund uses leverage because the fees will be calculated based on the Fund’s Managed Assets, which may create an incentive for the Adviser and Sub-Adviser to leverage the Fund or increase the Fund’s leverage.

Certain types of leverage used by the Fund may result in the Fund being subject to certain covenants, asset coverage or other portfolio composition limits by its lenders, preferred share purchasers, liquidity providers, rating agencies that may rate the preferred securities, or reverse repurchase counterparties. Such limitations may be more stringent than those imposed by the 1940 Act and may affect whether the Fund is able to maintain its desired amount of leverage. At this time, the Adviser does not believe that any such potential investment limitations will impede it from managing the Fund’s portfolio in accordance with its investment objectives and policies.

The Fund is required to maintain certain regulatory and rating agency asset coverage requirements in connection with its use of leverage, in order to be able to maintain the ability to declare and pay common share distributions. An NRSRO could downgrade its ratings on the Fund’s outstanding preferred shares. A ratings downgrade of the Fund’s preferred shares may result in higher dividend rates and may also force the redemption of such preferred shares at what might be an inopportune time in the market. These factors may result in reduced net earnings or returns to common shareholders.

In order to maintain required asset coverage levels, the Fund may be required to alter the composition of its investment portfolio or take other actions, such as redeeming preferred shares, or prepaying borrowings with

24

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. NRSRO ratings of the Fund’s outstanding preferred shares neither eliminate nor mitigate the risks of investing in common shares.

The Fund may invest in the securities of other investment companies, which may themselves be leveraged and therefore present similar risks to those described above and magnify the Fund’s leverage risk. The risk of loss attributable to the Fund’s use of leverage is borne by common shareholders.

Insurance Risk. The Fund may purchase municipal securities that are secured by insurance, bank credit agreements or escrow accounts. The credit quality of the companies that provide such credit enhancements will affect the value of those securities. Certain significant providers of insurance for municipal securities have incurred significant losses as a result of exposure to sub-prime mortgages and other lower credit quality investments that have experienced defaults or otherwise suffered extreme credit deterioration. As a result, such losses have reduced the insurers’ capital and called into question their continued ability to perform their obligations under such insurance if they are called upon to do so in the future. While an insured municipal security will typically be deemed to have the rating of its insurer, if the insurer of a municipal security suffers a downgrade in its credit rating or the market discounts the value of the insurance provided by the insurer, the rating of the underlying municipal security will be more relevant and the value of the municipal security would more closely, if not entirely, reflect such rating. In such a case, the value of insurance associated with a municipal security would decline and may not add any value. The insurance feature of a municipal security does not guarantee the full payment of principal and interest through the life of an insured obligation, the market value of the insured obligation or the net asset value of the common shares represented by such insured obligation.

Tax Risk. To qualify for the favorable federal income tax treatment generally accorded to a RIC, the Fund must, among other requirements, derive in each taxable year at least 90% of its gross income from certain prescribed sources and satisfy a diversification test on a quarterly basis. If the Fund fails to satisfy the qualifying income or diversification requirements in any taxable year, the Fund may be eligible for relief provisions if the failures are due to reasonable cause and not willful neglect and if a penalty tax is paid with respect to each failure to satisfy the applicable requirements. Additionally, relief is provided for certain de minimis failures of the diversification requirements where the Fund corrects the failure within a specified period. In order to be eligible for the relief provisions with respect to a failure to meet the diversification requirements, the Fund may be required to dispose of certain assets. If these relief provisions were not available to the Fund and it were to fail to qualify for treatment as a RIC for a taxable year, all of its taxable income (including its net capital gain) would be subject to federal income tax at the 21% regular corporate rate without any deduction for distributions to shareholders, and such distributions would be taxable to shareholders for federal income tax purposes as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits.

To qualify to pay exempt-interest dividends, which are treated as items of interest excludable from gross income for federal income tax purposes, at least 50% of the value of the total assets of the Fund must consist of obligations exempt from regular income tax as of the close of each quarter of the Fund’s taxable year. If the proportion of taxable investments held by the Fund exceeded 50% of the Fund’s total assets as of the close of any quarter of the Fund’s taxable year, the Fund would not for that taxable year satisfy the general eligibility test that would permit it to pay exempt-interest dividends for that taxable year.

The value of the 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 is normally not subject to regular federal income taxation, 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 the Fund’s net asset value and ability to acquire and dispose of municipal securities at desirable yield and price levels. Additionally, the Fund is not a suitable investment for individual retirement accounts, for other tax-exempt or

25

tax-advantaged accounts or for investors who are not sensitive to the federal income tax consequences of their investments.

Generally, the Fund’s investments in inverse floating rate securities do not generate taxable income for federal income tax purposes.

Taxability Risk. The 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 federal income tax purposes, and the Sub-Adviser will not independently verify that opinion. Subsequent to the 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 the Fund as “exempt-interest dividends” could be adversely affected, subjecting the Fund’s shareholders to increased federal income tax liabilities.

Distributions of taxable ordinary income (including any net short-term capital gain) will be taxable to shareholders as ordinary income (and not eligible for favorable taxation as “qualified dividend income”), and capital gain dividends will be taxable as long-term capital gains. See “Additional Information About the Acquiring Fund—Federal Income Tax Matters Associated with Investment in the Acquiring Fund.”

Borrowing Risk. Borrowing may exaggerate changes in the net asset value of the Fund’s common shares and may affect the Fund’s net income. When the 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 common shares and the distributions can decline. In addition, during any period of rising inflation, interest rates on borrowings would likely increase, which would tend to further reduce returns to common shareholders.

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 the Fund’s portfolio.

Derivatives Risk. The 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 the Fund’s use of derivatives is successful will depend on, among other things, if the Adviser and Sub-Adviser correctly forecast market values, interest rates and other applicable factors. If the Adviser and Sub-Adviser incorrectly forecast these and other factors, the investment performance of the Fund will be unfavorably affected. The derivatives market is subject to a changing regulatory environment.

Duration Risk. Duration is the sensitivity, expressed in years, of the price of a fixed-income security to changes in the general level of interest rates (or yields). Securities with longer durations tend to be more sensitive to interest rate (or yield) changes, which typically corresponds to increased volatility and risk, than securities with shorter durations. For example, if a security or portfolio has a duration of three years and interest rates increase by 1%, then the security or portfolio would decline in value by approximately 3%. Duration differs from maturity in that it considers potential changes to interest rates, and a security’s coupon payments, yield, price and par value and call features, in addition to the amount of time until the security matures. The duration of a security will be expected to change over time with changes in market factors and time to maturity.

26

Economic Sector Risk. The Fund may invest a significant amount of its total assets in municipal securities in the same economic sector. This may make the Fund more susceptible to adverse economic, political or regulatory occurrences affecting an economic sector. As concentration increases, so does the potential for fluctuation in the value of the Fund’s assets. In addition, the Fund may invest a significant portion of its assets in certain sectors of the municipal securities market, such as health care facilities, private educational facilities, special taxing districts and start-up utility districts, and private activity bonds including industrial development bonds on behalf of transportation companies, whose credit quality and performance may be more susceptible to economic, business, political, regulatory and other developments than other sectors of municipal issuers. If the Fund invests a significant portion of its assets in the sectors noted above, the Fund’s performance may be subject to additional risk and variability.

Sector Focus Risk. At times, the Fund may focus its investments (i.e., overweight its investments relative to the overall municipal securities market) in one or more particular sectors, which may subject the Fund to additional risk and variability. Securities issued in the same sector may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments in that sector than funds that invest more broadly. As the percentage of the Fund’s Managed Assets invested in a particular sector increases, so does the potential for fluctuation in the net asset value of the Fund’s common shares.

Swap Transactions Risk. The 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 and/or the Sub-Adviser not only of the referenced asset, rate or index, but also of the swap itself. If the Adviser and/or the Sub-Adviser is incorrect in its forecasts of default risks, market spreads or other applicable factors or events, the investment performance of the Fund would diminish compared with what it would have been if these techniques were not used. As the protection seller in a credit default swap, the Fund effectively adds economic leverage to its portfolio because, in addition to being subject to investment exposure on its total net assets, the Fund is subject to investment exposure on the notional amount of the swap.

The Fund generally may only close out a swap, cap, floor, collar or other two-party contract with its particular counterparty, and generally may only transfer a position with the consent of that counterparty. 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. In addition, the price at which the Fund may close out such a two-party contract may not correlate with the price change in the underlying reference asset. Moreover, the 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. If the counterparty defaults, the Fund will have contractual remedies, but there can be no assurance that the counterparty will be able to meet its contractual obligations or that the Fund will succeed in enforcing its rights.

The Fund may write (sell) and purchase put and call swap options. When the Fund purchases a swap option, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. When the Fund writes a swap option, upon exercise of the option the Fund would become obligated according to the terms of the underlying agreement.

Legislation and Regulatory Risk. At any time after the date of this Joint Proxy Statement/Prospectus, legislation or additional regulations may be enacted that could negatively affect the assets of the Fund, investments held by the Fund or the issuers of such investments. Changing approaches to regulation may have a negative impact on the entities and/or investments in which the Fund invests. Legislation or regulation may also change the way in which the Fund itself is regulated. Fund shareholders may incur increased costs resulting from such legislation or additional regulation. There can be no assurance that future legislation, regulation or deregulation will not have a material adverse effect on the Fund or will not impair the ability of the Fund to achieve its investment objective.

27

Additionally, the Fund is operated by persons who have claimed an exclusion, granted to operators of registered investment companies like the Fund, from registration as a “commodity pool operator” under Rule 4.5 promulgated by the Commodity Futures Trading Commission (“CFTC”) pursuant to its authority under the Commodity Exchange Act (the “CEA”) and, therefore, is not subject to registration or regulation as a “commodity pool operator.” As a result, the Fund is limited in its ability to use commodity futures (which include futures on broad-based securities indexes and interest rate futures) or options on commodity futures, engage in swaps transactions or make certain other investments (whether directly or indirectly through investments in other investment vehicles) for purposes other than bona fide hedging. With respect to transactions other than for bona fide hedging purposes, either: (1) the aggregate initial margin and premiums required to establish the Fund’s positions in such investments may not exceed 5% of the liquidation value of the Fund’s portfolio (after accounting for unrealized profits and unrealized losses on any such investments); or (2) the aggregate net notional value of such instruments, determined at the time the most recent position was established, may not exceed 100% of the liquidation value of the Fund’s portfolio (after accounting for unrealized profits and unrealized losses on any such positions). In addition to meeting one of the foregoing trading limitations, the Fund may not market itself as a commodity pool or otherwise as a vehicle for trading in the futures, options or swaps markets. If the Fund does not continue to claim the exclusion, it would likely become subject to registration and regulation as a commodity pool operator. The Fund may incur additional expenses as a result of the CFTC’s registration and regulatory requirements.

Clearing Broker and Central Clearing Counterparty Risk. The CEA requires swaps and futures clearing brokers registered as “futures commission merchants” to segregate all funds received from customers with respect to any orders for the purchase or sale of U.S. domestic futures contracts and cleared swaps from the brokers’ proprietary assets. Similarly, the CEA requires each futures commission merchant to hold in separate secure accounts all funds received from customers with respect to any orders for the purchase or sale of foreign futures contracts and cleared swaps and segregate any such funds from the funds received with respect to domestic futures contracts. However, all funds and other property received by a clearing broker from its customers are held by the clearing broker on a commingled basis in an omnibus account and may be invested in certain instruments permitted under applicable regulations. There is a risk that assets deposited by the Fund with any swaps or futures clearing broker as margin for futures contracts or cleared swaps may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing broker. In addition, the assets of the Fund might not be fully protected in the event of the Fund’s clearing broker’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing broker’s customers for the relevant account class.

Similarly, the CEA requires a clearing organization approved by the CFTC as a derivatives clearing organization to segregate all funds and other property received from a clearing member’s clients in connection with domestic cleared derivative contracts from any funds held at the clearing organization to support the clearing member’s proprietary trading. Nevertheless, all customer funds held at a clearing organization in connection with any futures contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. All customer funds held at a clearing organization with respect to cleared swaps of customers of a clearing broker are also held in an omnibus account, but CFTC rules require that the clearing broker notify the clearing organization of the amount of the initial margin provided by the clearing broker to the clearing organization that is attributable to each customer. With respect to futures and options contracts, a clearing organization may use assets of a non-defaulting customer held in an omnibus account at the clearing organization to satisfy payment obligations of a defaulting customer of the clearing member to the clearing organization. With respect to cleared swaps, a clearing organization generally cannot do so, but may do so if the clearing member does not provide accurate reporting to the clearing organization as to the attribution of margin among its clients. Also, since clearing brokers generally provide to clearing organizations the net amount of variation margin required for cleared swaps for all of its customers in the aggregate, rather than the gross amount of each customer, the Fund is subject to the risk that a clearing organization will not make variation margin payments owed to the Fund if another customer of the clearing member has suffered a loss and is in default. As a result, in the event of a default or the clearing broker’s other

28

clients or the clearing broker’s failure to extend its own funds in connection with any such default, the Fund may not be able to recover the full amount of assets deposited by the clearing broker on behalf of the Fund with the clearing organization.

Financial Futures and Options Risk. The Fund may use certain transactions for hedging the portfolio’s exposure to credit risk and the risk of increases in interest rates, which could result in poorer overall performance for the Fund. There may be an imperfect correlation between price movements of the futures and options and price movements of the portfolio securities being hedged.

If the Fund engages in futures transactions or in the writing of options on futures, it will be required to maintain initial margin and maintenance margin and may be required to make daily variation margin payments in accordance with applicable rules of the exchanges and the Commodity Futures Trading Commission (“CFTC”). If the Fund purchases a financial futures contract or a call option or writes a put option in order to hedge the anticipated purchase of municipal securities, and if the Fund fails to complete the anticipated purchase transaction, the Fund may have a loss or a gain on the futures or options transaction that will not be offset by price movements in the municipal securities that were the subject of the anticipatory hedge. There can be no assurance that a liquid market will exist at a time when the Fund seeks to close out a derivatives or futures or a futures option position, and the Fund would remain obligated to meet margin requirements until the position is closed.

Hedging Risk. The Fund’s use of derivatives or other transactions to reduce risk involves costs and will be subject to the Adviser and Sub-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 and Sub-Adviser’s judgment in this respect will be correct. In addition, no assurance can be given that the Fund will enter into hedging or other transactions at times or under circumstances in which it may be advisable to do so.

Other Investment Companies Risk. The Fund may invest in the securities of other investment companies. Such securities may be leveraged. As a result, the 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 the Fund to higher volatility in the market value of such securities and the possibility that the Fund’s long-term returns on such securities (and, indirectly, the long-term returns of the common shares) will be diminished. Additionally, the Fund, as a holder of the securities of other investment companies, will bear its pro rata portion of other investment companies’ expenses, including advisory fees. These expenses are in addition to the direct expenses of the Fund’s own operations. An ETF that is based on a specific index, whether stock or otherwise, may not be able to replicate and maintain exactly the composition and relative weighting of securities in the index. An ETF also incurs certain expenses not incurred by its applicable index. The market value of shares of ETFs and closed-end funds may differ from their net asset value.

Counterparty Risk. Changes in the credit quality of the companies that serve as the 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, the Fund assumes the risk that its counterparties could experience similar financial hardships.

Reverse Repurchase Agreement Risk. Reverse repurchase agreements involve the sale of securities held by the Fund with an agreement to repurchase the securities at an agreed-upon price and date, thereby establishing an effective interest rate. The Fund’s use of reverse repurchase agreements, in economic essence, constitute a

29

secured borrowing by the Fund from the security purchaser. The Fund may enter into reverse repurchase agreements for the purpose of creating a leveraged investment exposure and, as such, their usage involves essentially the same risks associated with a leveraging strategy generally since the proceeds from these agreements may be invested in additional securities. Reverse repurchase agreements tend to be short-term in tenor, and there can be no assurances that the purchaser (lender) will commit to extend or “roll” a given agreement upon its agreed-upon repurchase date or an alternative purchaser can be identified on similar terms.

Reverse repurchase agreements also involve the risk that the purchaser fails to return the securities as agreed upon, files for bankruptcy or becomes insolvent. The Fund may be restricted from taking normal portfolio actions during such time, could be subject to loss to the extent that the proceeds of the agreement are less than the value of securities subject to the agreement and may experience adverse tax consequences.

Illiquid Investments Risk. The Fund may invest in municipal securities and other instruments that, at the time of investment, are illiquid. Illiquid investments are securities that are not readily marketable. These securities may include restricted securities, which cannot be resold to the public without an effective registration statement under the 1933 Act or, if they are unregistered, may be sold only in a privately negotiated transaction or pursuant to an exemption from registration. The Fund may not be able to readily dispose of such securities at prices that approximate those at which the Fund could sell such securities if they were more widely traded and, as a result of such illiquidity, the Fund may have to sell other investments or engage in borrowing transactions if necessary to raise cash to meet its obligations. Limited liquidity can also affect the market price of securities, thereby adversely affecting the Fund’s net asset value and ability to make dividend distributions. The financial markets in general have in recent years experienced periods of extreme secondary market supply and demand imbalance, resulting in a loss of liquidity during which market prices were suddenly and substantially below traditional measures of intrinsic value. During such periods, some securities could be sold only at arbitrary prices and with substantial losses. Periods of such market dislocation may occur again at any time.

Municipal Securities Market Liquidity Risk. Inventories of municipal bonds held by brokers and dealers have decreased in recent years, lessening their ability to make a market in these securities. This reduction in market making capacity has the potential to decrease the Fund’s ability to buy or sell bonds, and increase bond price volatility and trading costs, particularly during periods of economic or market stress. In addition, recent changes to federal banking regulations may cause certain dealers to reduce their inventories of municipal bonds, which may further decrease the Fund’s ability to buy or sell bonds. As a result, the Fund may be forced to accept a lower price to sell a security, to sell other securities to raise cash, or to give up an investment opportunity, any of which could have a negative effect on performance. If the Fund needed to sell large blocks of bonds, those sales could further reduce the bonds’ prices and hurt performance.

Income Risk. The 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, the 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. During periods of declining interest rates or for other purposes, issuers may exercise their option to prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding instruments. This is known as prepayment or “call” risk. The Fund may invest in securities that are subject to call risk. Debt and preferred instruments may be redeemed at the option of the issuer, or “called,” before their stated maturity or redemption date. In general, an issuer will call its debt or preferred instruments if they can be refinanced by issuing new instruments which bear a lower interest or dividend rate. The Fund is subject to the possibility that during periods of falling interest rates, an issuer will call its debt. The Fund would then be forced to invest the unanticipated proceeds at lower interest or dividend rates, resulting in a decline in the Fund’s income.

Reinvestment Risk. Reinvestment risk is the risk that income from the 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 portfolio’s current earnings rate. A decline in income could affect the common shares’ market price or their overall returns.

30

Sector and Industry Risk. Subject to the concentration limits of the Fund’s investment policies and guidelines, the Fund may invest a significant portion of its net assets in certain sectors of the municipal securities market, such as hospitals and other health care facilities, charter schools and other private educational facilities, special taxing districts and start-up utility districts, and private activity bonds including industrial development bonds on behalf of transportation companies such as airline companies, whose credit quality and performance may be more susceptible to economic, business, political, regulatory and other developments than other sectors of municipal issuers. If the Fund invests a significant portion of its net assets in the sectors noted above, the Fund’s performance may be subject to additional risk and variability. To the extent that the Fund focuses its net assets in the hospital and healthcare facilities sector, for example, the Fund will be subject to risks associated with such sector, including adverse government regulation and reduction in reimbursement rates, as well as government approval of products and services and intense competition. Securities issued with respect to special taxing districts will be subject to various risks, including real-estate development related risks and taxpayer concentration risk. Further, the fees, special taxes or tax allocations and other revenues established to secure the obligations of securities issued with respect to special taxing districts 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. Charter schools and other private educational facilities are subject to various risks, including the reversal of legislation authorizing or funding charter schools, the failure to renew or secure a charter, the failure of a funding entity to appropriate necessary funds and competition from alternatives such as voucher programs. Issuers of municipal utility securities can be significantly affected by government regulation, financing difficulties, supply and demand of services or fuel and natural resource conservation. The transportation sector, including airports, airlines, ports and other transportation facilities, can be significantly affected by changes in the economy, fuel prices, labor relations, insurance costs and government regulation.

Valuation Risk. The municipal securities in which the Fund invests typically are valued by a pricing service utilizing a range of market-based inputs and assumptions, including readily available market quotations obtained from broker-dealers making markets in such instruments, cash flows and transactions for comparable instruments. There is no assurance that the Fund will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the Fund. Pricing services generally price municipal securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, often at lower prices than institutional round lot trades. Different pricing services may incorporate different assumptions and inputs into their valuation methodologies, potentially resulting in different values for the same securities. As a result, if the Fund were to change pricing services, or if the Fund’s pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Fund’s net asset value.

Cybersecurity Risk. Technology, such as the Internet, has become more prevalent in the course of business, and as such, the Fund and its service providers are susceptible to operational and information security risk resulting from cyber incidents. Cyber incidents refer to both intentional attacks and unintentional events including: processing errors, human errors, technical errors including computer glitches and system malfunctions, inadequate or failed internal or external processes, market-wide technical-related disruptions, unauthorized access to digital systems (through “hacking” or malicious software coding), computer viruses, and cyber-attacks which shut down, disable, slow or otherwise disrupt operations, business processes or website access or functionality (including denial of service attacks). Cyber incidents could adversely impact the Fund and cause the Fund to incur financial loss and expense, as well as face exposure to regulatory penalties, reputational damage, and additional compliance costs associated with corrective measures. Cyber incidents may cause the Fund or its service providers to lose proprietary information, suffer data corruption, lose operational capacity or fail to comply with applicable privacy and other laws. Among other potentially harmful effects, cyber incidents also may result in theft, unauthorized monitoring and failures in the physical infrastructure or operating systems that support the Fund and its service providers. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. While the Fund’s service providers have established business continuity plans in the event of, and risk management systems to prevent, such cyber incidents, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, the Fund cannot control the cybersecurity plans and systems put in place by its service providers or any other third parties whose operations may affect the Fund.

31

Anti-Takeover Provisions. The Fund’s Declaration of Trust and By-laws include provisions that could limit the ability of other entities or persons to acquire control of the Fund, change the composition of its Board of Trustees or convert the Fund to open-end status. These provisions include, among others, staggered terms of office for the Trustees, advance notice requirements for shareholder proposals and super-majority voting requirements for certain transactions. These provisions 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. See “Additional Information About the Acquiring Fund—Certain Provisions in the Acquiring Fund’s Declaration of Trust and By-Laws.”

C. | INFORMATION ABOUT THE MERGER

General

Nuveen Fund Advisors, LLC, the Funds’ investment adviser, recommended the proposed Merger. Each Fund’s Board considered the Merger and determined that the Merger would be in the best interests of its Fund. Based on information provided by Nuveen Fund Advisors, the Target Fund’s Board believes that the proposed Merger may benefit the common shareholders of the Target Fund in a number of ways, including, among other things:

| • |  | The potential for higher common share net earnings and distribution levels following the Merger, due in part to the Acquiring Fund’s ability to invest to a greater degree in lower rated securities and a geographically diverse national portfolio, as well as operating economies from the combined fund’s greater scale;

| • |  | Greater secondary market liquidity and improved secondary market trading for common shares as a result of the combined fund’s greater share volume, which may lead to narrower bid-ask spreads and smaller trade-to-trade price movements;

| • |  | The potential for a narrower trading discount as a result of the Acquiring Fund’s common shares trading at a discount that, on average, has been lower over the prior twelve months from June 30, 2023 than that of the Target Fund’s common shares;

| • |  | Increased portfolio and leverage management flexibility due to the significantly larger asset base of the combined fund and the Acquiring Fund’s national mandate with greater flexibility to invest in lower rated securities; and

| • |  | Lower net operating expenses, excluding the costs of leverage, as certain fixed costs are spread over a larger asset base.

The Target Fund’s Board considered that a greater percentage of the Acquiring Fund’s portfolio may be allocated to lower rated municipal securities relative to the amount permitted by the policies of the Target Fund, and recognized that investments in lower rated securities are subject to higher risks than investments in higher rated securities. The Target Fund’s Board also noted that as a result of the Merger and the Acquiring Fund’s national mandate, it was expected that the benefit to Target Fund shareholders of any state tax exemption from investing in a state-specific municipal fund would be lost or largely unavailable.

With respect to holders of preferred shares of the Target Fund, the Target Fund’s Board considered that, upon the closing of the Merger, holders of preferred shares of the Target Fund outstanding immediately prior to the closing will receive, on a one-for-one basis, newly issued preferred shares of the Acquiring Fund having substantially similar terms to those of the preferred shares of the Target Fund immediately prior to the closing of the Merger.

Based on information provided by Nuveen Fund Advisors, the Acquiring Fund’s Board considered that the Acquiring Fund may benefit in the near term from a modest increase in common share net earnings and operating efficiencies and over the long term from increased investment capital, which allows the Acquiring Fund to pursue additional investment opportunities. With respect to holders of preferred shares of the Acquiring Fund, the Acquiring Fund’s Board considered that the outstanding preferred shares of the Acquiring Fund and any preferred shares of the Acquiring Fund to be issued in the Merger would have equal priority with each other as to the payment of dividends and distributions of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund.

For these reasons, each Fund’s Board has determined that the Merger is in the best interest of its Fund and has approved the Merger.

The closing of the Merger is subject to the satisfaction or waiver of certain closing conditions, which include customary closing conditions. In order for the Merger to occur, all requisite shareholder approvals must be obtained at the applicable Fund’s shareholder meeting, and certain other consents, confirmations and/or waivers from various third parties, including the liquidity providers and/or certain purchasers of the outstanding preferred shares of the Fund, must also be obtained. Because the closing of the Merger is contingent upon the Target Fund and the Acquiring Fund obtaining such shareholder approvals and satisfying (or obtaining the waiver of) other closing conditions, it is possible that the Merger will not occur even if shareholders of a Fund entitled to vote approve the Merger and a Fund satisfies all of its closing conditions if the other Fund does not obtain its requisite shareholder approvals or satisfy (or obtain the waiver of) its closing conditions. If the Merger is not consummated, the Board of the Target Fund may take such actions as it deems in the best interests of the Fund, including conducting additional solicitations with respect to the Merger proposal or continuing to operate the Target Fund as a standalone fund.

Terms of the Merger

General. The Agreement and Plan of Merger by and among the Acquiring Fund, the Target Fund and the Merger Sub (the “Agreement”), in the form attached as Appendix A to this Joint Proxy Statement/Prospectus, sets forth the terms of the Merger and provides for: (1) the merger of the Target Fund with and into the Merger Sub, with the Merger Sub continuing as the surviving company and the separate legal existence of the Target Fund ceasing for all purposes at the Effective Time (as defined below); (2) the conversion of the issued and outstanding common shares of beneficial interest of the Target Fund into newly issued common shares of beneficial interest of the Acquiring Fund, par value $0.01 per share (with cash being received in lieu of any fractional Acquiring Fund common shares), and (3) the conversion of the issued and outstanding VRDP Shares of the Target Fund into 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. With respect to the Merger, at the Effective Time, without any further action, the Merger Sub as the surviving company shall (i) succeed to and possess all rights, powers and privileges of the Merger Sub and the Target Fund, and all of the assets and property of whatever kind and character of the Target Fund and the Merger Sub shall vest in the Merger Sub, and (ii) be liable for all of the liabilities and obligations of the Target Fund and the Merger Sub. As soon as practicable following the completion of the Merger, the Merger Sub will distribute its assets to the Acquiring Fund and the Acquiring Fund will assume the liabilities of the Merger Sub in complete liquidation and dissolution of the Merger Sub under Massachusetts law. The Merger Sub has been formed for the sole purpose of consummating the Merger and the Merger Sub will not commence operations prior to the closing of the Merger, except as necessary to facilitate the Merger.

As a result of the Merger and subsequent distribution of assets to the Acquiring Fund, the assets of the Acquiring Fund and the Target Fund would be combined, and the shareholders of the Target Fund would become shareholders of the Acquiring Fund. The Acquiring Fund will be the accounting survivor of the Merger.

33

Each preferred shareholder of the Target Fund will receive the same number of Acquiring Fund VRDP Shares having substantially similar terms as the outstanding VRDP Shares of the Target Fund held by such preferred shareholder immediately prior to the closing of the Merger. The aggregate liquidation preference of the Acquiring Fund VRDP Shares received in connection with the Merger will equal the aggregate liquidation preference of the Target Fund VRDP Shares held immediately prior to the closing of the Merger. The Acquiring Fund VRDP Shares to be issued in connection with the Merger 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 upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund. In addition, the preferred shares of the Acquiring Fund, including any VRDP Shares of the Acquiring Fund to be issued in connection with the Merger, will be senior in priority to the Acquiring Fund’s common shares as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund. However, the Acquiring Fund has multiple types and series of preferred shares outstanding.

The closing date is expected to be on or about [●], 2023, or such other date as the parties may agree (the “Closing Date”). Following the Merger, the Target Fund will terminate its registration as an investment company under the 1940 Act. The Acquiring Fund will continue to operate after the Merger 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, as of the Valuation Time (as defined below), of the Acquiring Fund common shares received by the Target Fund’s common shareholders in connection with the Merger will equal the aggregate net asset value of the Target Fund common shares held by shareholders of the Target Fund as of the Valuation Time. Prior to the Valuation Time, the net asset value of each Fund will be reduced by the costs of the Merger borne by such Fund. See “—Description of Common Shares to Be Issued by the Acquiring Fund; Comparison to Target Fund” for a description of the rights of Acquiring Fund common shareholders. However, no fractional Acquiring Fund common shares will be distributed to the Target Fund’s common shareholders in connection with the Merger. The Acquiring Fund’s transfer agent will aggregate all fractional Acquiring Fund common shares that may be due to the Target Fund’s 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 the Target Fund shareholders entitled to receive the fractional shares (without interest and subject to withholding taxes). For federal income tax purposes, Target Fund 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 the Acquiring Fund shares received by a shareholder, including fractional share interests deemed received by a shareholder, will be the same as the holding period and aggregate tax basis of the Target Fund common shares previously held by the shareholder, provided the Target Fund shares were held as capital assets at the effective time of the Merger. As a result of the Merger, common shareholders of the Funds will hold a smaller percentage of the outstanding common shares of the combined fund as compared to their percentage holdings of their respective Fund prior to the Merger and thus, common shareholders will hold reduced percentages of ownership in the larger combined entity than they held in the Acquiring Fund or the Target Fund individually.

Following the Merger, each preferred shareholder of the Target Fund would own the same number of Acquiring Fund VRDP Shares with the same aggregate liquidation preference as the VRDP Shares of the Target Fund held by such shareholder immediately prior to the closing of the Merger, with substantially similar terms as the outstanding VRDP Shares of the Target Fund held by such preferred shareholder immediately prior to the closing of the Merger. However, the Acquiring Fund has multiple series and multiple types of preferred shares outstanding. As a result of the Merger, preferred shareholders of the Funds may hold reduced voting percentages of preferred shares in the combined fund than they held in the Acquiring Fund or the Target Fund individually.

34

Valuation of Common Shares. Pursuant to the Agreement, the net asset value per share of the Target Fund and the Acquiring Fund shall be 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 referred to herein as the “Valuation Time”) using the valuation procedures of the Nuveen closed-end funds or such other valuation procedures as will be mutually agreed upon by the parties.

Acquiring Fund Common Shares to be Issued. At the effective time of the closing (the “Effective Time”), each Target Fund common share outstanding immediately prior to the Effective Time shall be converted into a number of Acquiring Fund common shares equal to one multiplied by the quotient of the net asset value per common share of the Target Fund divided by the net asset value per common share of the Acquiring Fund.

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, if the Target Fund has undistributed net investment income or undistributed net capital gains, the Target Fund is required to declare a distribution prior to the Valuation Time, which, together with all previous dividends, has 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 and excluding any net capital gain on which the Target Fund paid federal income tax) 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 to its shareholders. Consequently, Target 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 Target Fund’s undistributed net investment income and undistributed realized net capital gains 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 Merger 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 Merger.

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 receipt of shareholder approval of the Agreement, 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 Target Fund’s 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 Merger is subject to the satisfaction or waiver (if permissible) of the following closing conditions: (1) the requisite approval by the common and preferred shareholders of the Target Fund and the preferred shareholders of the Acquiring Fund of the proposal with respect to the Merger described in this Joint Proxy Statement/Prospectus, (2) as a non-waivable condition, each Fund’s receipt of an opinion of counsel substantially to the effect that the merger of the Target Fund with and into the Merger Sub will qualify as a reorganization under the Code (see “—Material Federal Income Tax Consequences of the Merger”), (3) the absence of legal proceedings challenging the Merger, and (4) the Funds’ receipt of certain customary certificates and legal opinions. Additionally, in order for the Merger to occur, certain other consents, confirmations and/or waivers from various third parties, including the liquidity providers and/or certain purchasers of the outstanding preferred shares of the Funds, must also be obtained.

Termination. With respect to the Merger, the Agreement may be terminated by the mutual agreement of the parties, and such termination may be effected by the Chief Administrative Officer, President or any Vice President of each Fund without further action by the Target Fund’s Board or the Acquiring Fund’s Board. In

35

addition, a Fund may at its option terminate the Agreement with respect to the Merger at or before the closing due to: (1) a breach by the non-terminating party of any representation or warranty, or agreement to be performed at or before the closing, if not cured within 30 days of the breach and prior to the closing; (2) a condition precedent to the obligations of the terminating party that has not been met or waived and it reasonably appears that it will not or cannot be met; or (3) a determination by the Target Fund’s Board or the Acquiring Fund’s Board that the consummation of the transactions contemplated by the Agreement is not in the best interests of its respective Fund.

Reasons for the Merger

Based on the considerations described below, the Board of Trustees of the Target Fund (the “Target Board”), all of whom are not “interested persons,” as defined in the 1940 Act, and the Board of Trustees of the Acquiring Fund (the “Acquiring Board” and together with the Target Board, the “Boards” and each individually, a “Board”), all of whom are not “interested persons,” as defined in the 1940 Act, have each determined that the Merger would be in the best interests of its Fund and that the interests of the existing shareholders of its Fund would not be diluted as a result of the Merger. At a meeting held on August 8-10, 2023 (the “Board Meeting”), each Board approved the Merger and recommended that shareholders of its Fund, as applicable, approve the Merger.

At and prior to the Board Meeting, including at previous meetings, Nuveen Fund Advisors made presentations and provided the Boards with information relating to the proposed Merger and alternatives to the proposed Merger. Prior to approving the Merger, each Board reviewed the foregoing information with its independent legal counsel and with management, reviewed with independent legal counsel applicable law and its duties in considering such matters and met with independent legal counsel in private sessions without management present. Each Board recognized that Nuveen Fund Advisors, each Fund’s investment adviser, had recommended the Merger proposal. Based on the foregoing, the Boards considered the following factors (as applicable), among others, in approving the Merger and recommending that shareholders of the Funds (as applicable) approve the Merger:

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

| • |  | the consistency of portfolio management;

| • |  | the larger asset base of the combined fund as a result of the Merger and the effect of the Merger on fees and expense ratios;

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

| • |  | the anticipated federal income tax-free nature of the Merger;

| • |  | the expected costs of the Merger;

| • |  | the terms of the Merger and whether the Merger would dilute the interests of the shareholders of the Funds;

| • |  | the effect of the Merger on shareholder rights;

| • |  | alternatives to the Merger; and

| • |  | any potential benefits of the Merger to Nuveen Fund Advisors and its affiliates as a result of the Merger.

36

Compatibility of Investment Objectives, Policies and Related Risks. Based on the information presented, the Boards noted that, as municipal funds, the Funds’ investment objectives and policies share certain similarities, but there are differences. The Acquiring Fund is a national municipal fund that seeks to provide current income exempt from regular federal income tax and the federal alternative minimum tax applicable to individuals. In contrast, the Target Fund is a state-specific municipal fund that seeks to provide current income exempt from both regular federal income tax and the income tax of a single state. In its review, each Board considered the impact of the Merger on its Fund’s portfolio, including any shifts in credit quality and yield. In this regard, the Target Board recognized that a greater percentage of the Acquiring Fund’s portfolio may be allocated to lower rated municipal securities relative to the amount permitted by the policies of the Target Fund. The Target Board further observed the significantly larger asset size of the Acquiring Fund compared to that of the Target Fund. The Target Board noted that it was expected that the benefit to Target Fund shareholders of any state tax exemption would be lost or largely unavailable as a result of the Merger, but recognized the potential for higher common share net earnings and distribution levels of the combined fund as a result of, among other things, the Acquiring Fund’s ability to invest to a greater degree in lower rated securities, the geographically diverse national portfolio and the operating economies from the combined fund’s greater scale following the Merger. Further, in comparison to the Target Fund, the Target Board recognized the increased portfolio and leverage management flexibility afforded by the significantly larger asset base of the combined fund and the Acquiring Fund’s national mandate with greater flexibility to invest in lower rated securities.

The Boards considered that each Fund may use leverage through a number of methods, including through the issuance of preferred shares and investments in inverse floating rate securities. In this regard, the Boards recognized, among other things, that the Target Fund has one series of VRDP Shares outstanding, and the Acquiring Fund has four series of MFP Shares outstanding, one series of AMTP Shares outstanding and four series of VRDP Shares outstanding. The preferred shares of the Acquiring Fund are expected to remain outstanding following the Merger. With respect to holders of preferred shares of the Target Fund, the Target Board considered that upon the closing of the Merger, holders of preferred shares of the Target Fund outstanding immediately prior to the closing will receive, on a one-for-one basis, newly issued preferred shares of the Acquiring Fund having substantially similar terms to those of the preferred shares of the Target Fund immediately prior to the closing of the Merger.

With respect to the Acquiring Fund, the Acquiring Board considered that based on information provided by Nuveen Fund Advisors, the Acquiring Fund may benefit in the near term from a modest increase in common share net earnings and operating efficiencies and over the long term from increased investment capital, which allows the Acquiring Fund to pursue additional investment opportunities. The Acquiring Board also recognized that the outstanding preferred shares of the Acquiring Fund and any preferred shares of the Acquiring Fund to be issued in the Merger would have equal priority with each other as to the payment of dividends and distributions of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund.

With respect to principal investment risks, while the principal risks of an investment in each Fund would be similar in certain respects because each Fund invests in municipal securities and other investments the income from which is exempt from regular federal income taxes, the differences relating to the Funds’ investment objectives and policies may affect the comparative risk profiles. For example, the Target Fund is subject to single state risk while the Acquiring Fund is not. The Target Fund also invests primarily in investment grade securities, while the Acquiring Fund is permitted to allocate a greater percentage of its portfolio to lower rated municipal securities than the Target Fund. Investments in lower rated securities are subject to greater risks than investments in higher rated securities. The Acquiring Fund therefore would be subject to increased risks from investments in lower rated securities, including a higher risk that the issuer will be unable to pay interest or principal when due.

Consistency of Portfolio Management. Each Fund has the same investment adviser and sub-adviser, but the portfolio manager of the Acquiring Fund is different from the portfolio manager of the Target Fund. The portfolio manager of the Acquiring Fund will continue to manage the combined fund upon completion of the

37

Merger. Through the Merger, the Boards recognized that shareholders would remain invested in a closed-end management investment company that will have greater net assets and the same investment adviser and sub-adviser.

Larger Asset Base of the Combined Fund; Effect of the Merger on Fees and Expense Ratios. The Boards evaluated the fees and expense ratios of each of the Funds (including estimated expenses of the combined fund following the Merger). It was anticipated that the Funds will benefit from the larger asset size as fixed costs are shared over a larger asset base. The Target Board also considered that the fund-level management fee schedule of the Acquiring Fund was the same as that of the Target Fund at each breakpoint level. The Target Board further noted that it was expected that the net operating expenses per common share (i.e., expenses excluding the costs of leverage) of the combined fund would be lower than those of the Target Fund prior to the closing of the Merger.

Potential for Improved Secondary Market Trading. While it is not possible to predict trading levels following the Merger, the Target Board noted that the Merger is being proposed, in part, to seek to enhance the secondary trading market for the common shares with respect to the Target Fund. The Target Board considered that, relative to the Target Fund, the combined fund’s greater share volume may result in greater secondary market liquidity and improved secondary market trading for common shares after the Merger, which may lead to narrower bid-ask spreads and smaller trade-to-trade price movements. In addition, based on information provided by Nuveen Fund Advisors, the Target Board considered the potential for a narrower trading discount, relative to the Target Fund, as a result of the Acquiring Fund’s common shares trading at a discount that, on average, has been lower over the prior twelve months from June 30, 2023 than that of the Target Fund’s common shares; however, the Target Board recognized that the past trading record of the common shares of the Acquiring Fund may not necessarily be indicative of how the common shares of the combined fund will trade in the future and there is no guarantee that the common shares of the combined fund would have a narrower trading discount than that of the Target Fund’s common shares. Further, with respect to the Acquiring Fund, the Acquiring Board noted that such Fund may experience modest secondary market benefits with respect to its common shares due to increased scale.

Anticipated Tax-Free Reorganization; Capital Loss Carryforwards. The Merger will be structured with the intention that it qualifies as a tax-free reorganization for federal income tax purposes, and each Fund will obtain an opinion of counsel substantially to this effect (based on certain factual representations and certain customary assumptions and exclusions). In addition, the Boards considered the impact of the Merger on any estimated capital loss carryforwards of the Funds and applicable limitations of federal income tax rules.

Expected Costs of the Merger. The Boards considered the terms and conditions of the Merger, including the estimated costs associated with the Merger and the allocation of such costs between the Funds. Preferred shareholders will not bear any costs of the Merger.

Terms of the Merger and Impact on Shareholders. The terms of the Merger are intended to avoid dilution of the interests of the existing shareholders of the Funds. In this regard, the Target Board considered that each holder of common shares of the Target Fund will receive common shares of the Acquiring Fund (taking into account any fractional shares to which the shareholder would be entitled) equal in value as of the Valuation Time to the aggregate per share net asset value of that shareholder’s Target Fund common shares held as of the Valuation Time. However, no fractional common shares of the Acquiring Fund will be distributed to the Target Fund’s common shareholders in connection with the Merger. In lieu of such fractional shares, the Target Fund’s common shareholders will receive cash. As noted above with respect to holders of preferred shares of the Target Fund, upon the closing of the Merger, holders of preferred shares of the Target Fund outstanding immediately prior to the closing will receive, on a one-for-one basis, newly issued preferred shares of the Acquiring Fund having substantially similar terms to those of the preferred shares of the Target Fund immediately prior to the closing of the Merger.

In conjunction with the issuance of additional shares of the Acquiring Fund as described above, the Acquiring Board considered that the Acquiring Fund would receive additional assets and liabilities as a result of

38

the Merger. Further, as noted above, the outstanding preferred shares of the Acquiring Fund and any preferred shares of the Acquiring Fund to be issued in the Merger would have equal priority with each other as to the payment of dividends and distributions of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund.

Effect on Shareholder Rights. The Boards considered that each Fund is organized as a Massachusetts business trust. In this regard, with respect to the Target Fund, there will be no change to shareholder rights under state statutory law.

Alternatives. The Target Board considered various alternatives to the Merger, including keeping the status quo, liquidating the Target Fund, and merging the Target Fund into a state-specific open-end fund. In considering the status quo, the Target Board considered Nuveen Fund Advisors’ view, among other things, that while the Target Fund would maintain the state income tax exemption, this option may result in continuing secondary market trading discounts and less competitive tax-adjusted distributions. In considering liquidation, the Target Board took into account, among other things, that such alternative would be a taxable event and could be potentially disruptive to long-term shareholders. With respect to a merger into a state-specific open-end fund, the Target Board considered, among other things, that while the Target Fund would maintain the state income tax exemption, based on the information provided by Nuveen Fund Advisors, this option may result in potentially lower tax-free earnings over time and be disruptive to acquiring fund shareholders. In evaluating the proposed Merger, the Target Board considered, among other things, Nuveen Fund Advisors’ view that combining the Target Fund with a larger closed-end municipal fund with a national mandate was an attractive alternative in light of certain potential benefits to shareholders of the Target Fund, as outlined above.

Potential Benefits to Nuveen Fund Advisors and Affiliates. The Boards recognized that the Merger may result in some benefits and economies of scale for Nuveen Fund Advisors 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 Target Fund as a separate fund in the Nuveen complex.

Conclusion. Each Board approved the Merger on behalf of its Fund, concluding that the Merger is in the best interests of its Fund and that the interests of existing shareholders of its Fund will not be diluted as a result of the Merger.

Capitalization

The following table sets forth the unaudited capitalization of the Funds as of July 31, 2023, and the pro-forma combined capitalization of the Acquiring Fund as if the Merger had occurred on that date. The table reflects a pro forma exchange ratio of approximately 0.95927985 common shares of the Acquiring Fund issued for each common share of the Target Fund. If the Merger is consummated, the actual exchange ratio may vary.

Expenses Associated with the Merger

Preferred shareholders will not bear any costs of the Merger. The costs of the Merger are estimated to be $1,325,000, but the actual costs may be higher or lower than that amount. These costs represent the estimated nonrecurring expenses of the Funds in carrying out their obligations under the Agreement and consist of management’s estimate of professional service fees, printing costs and mailing charges related to the proposed Merger. Based on the expected benefits of the Merger to each Fund, the Target Fund and the Acquiring Fund are expected to be allocated $845,000 and $480,000, respectively, of the estimated expenses in connection with the Merger (0.74% and 0.01%, respectively, of the Target Fund’s and the Acquiring Fund’s average net assets applicable to common shares for the six months ended April 30, 2023). If the Merger is not consummated for any reason, including because the requisite shareholder approvals are not obtained, each of the Funds, and common shareholders of each of the Funds indirectly, will still bear the costs of the Merger.

The Funds have engaged Computershare Fund Services to assist in the solicitation of proxies at an estimated aggregate cost of $[●] per Fund plus reasonable expenses, which is included in the foregoing estimate.

Dissenting Shareholders’ Rights of Appraisal

Under the charter documents of the Funds, shareholders do not have dissenters’ rights of appraisal with respect to their shares in connection with the Merger.

Material Federal Income Tax Consequences of the Merger

As a non-waivable condition to each Fund’s obligation to consummate the Merger, 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 and exclusions) with respect to the Merger 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:

| (a) | The merger of the Target Fund with and into the Merger Sub pursuant to applicable state laws will constitute a “reorganization” within the meaning of Section 368(a) of the Code and the Acquiring Fund and the Target Fund will each be a “party to a reorganization,” within the meaning of Section 368(b) of the Code, with respect to the merger.

| (b) | No gain or loss will be recognized by the Acquiring Fund or the Merger Sub upon the merger of the Target Fund with and into the Merger Sub pursuant to applicable state laws or upon the liquidation of the Merger Sub.

| (c) | No gain or loss will be recognized by the Target Fund upon the merger of the Target Fund with and into the Merger Sub pursuant to applicable state laws.

| (d) | No gain or loss will be recognized by the Target Fund shareholders upon the conversion of all their Target Fund shares solely into Acquiring Fund shares in the merger of the Target Fund with and into the Merger Sub pursuant to applicable state laws, except to the extent the Target Fund common shareholders receive cash in lieu of a fractional Acquiring Fund common share.

| (e) | The aggregate basis of the Acquiring Fund shares received by each Target Fund shareholder pursuant to the merger (including any fractional Acquiring Fund common share to which a Target

41

| Fund common shareholder would be entitled) will be the same as the aggregate basis of the Target Fund shares that were converted into such Acquiring Fund shares.

| (f) | The holding period of the Acquiring Fund shares received by each Target Fund shareholder in the merger (including any fractional Acquiring Fund common share to which a Target Fund common shareholder would be entitled) will include the period during which the shares of the Target Fund that were converted into such Acquiring Fund shares were held by such shareholder, provided the Target Fund shares are held as capital assets at the effective time of the merger.

| (g) | The basis of the Target Fund’s assets received by the Merger Sub in the merger will be the same as the basis of such assets in the hands of the Target Fund immediately before the merger.

| (h) | The holding period of the assets of the Target Fund received by the Merger Sub in the merger will include the period during which those assets were held by the Target Fund.

The opinion addressing the federal income tax consequences of the Merger described above will rely on the assumption that the Acquiring Fund VRDP Shares received in the Merger, if any, will constitute equity of the Acquiring Fund. In that regard, Stradley Ronon Stevens & Young, 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 any Acquiring Fund VRDP Shares received in the Merger by the holders of VRDP Shares of the Target Fund will qualify as equity of the Acquiring Fund for federal income tax purposes. As a result, distributions with respect to the preferred shares (other than distributions in redemption of preferred shares subject to Section 302(b) of the Code) will generally constitute dividends to the extent of the Acquiring Fund’s allocable current or accumulated earnings and profits, as calculated for federal income tax purposes. Because the treatment of a corporate security as debt or equity is determined on the basis of the facts and circumstances of each case, and no controlling precedent exists for the preferred shares issued in the Merger, there can be no assurance that the Internal Revenue Service (“IRS”) will not question special tax counsel’s opinion and the Acquiring Fund’s treatment of the preferred shares as equity. If the IRS were to succeed in such a challenge, holders of preferred shares could be characterized as receiving taxable interest income rather than exempt-interest or other dividends, possibly requiring them to file amended income tax returns and retroactively to recognize additional amounts of ordinary income and pay additional tax, interest and penalties, and the tax consequences of the Merger could differ significantly from those described in this Joint Proxy Statement/Prospectus.

No opinion will be expressed as to (1) the effect of the Merger on the Target Fund, the Acquiring Fund, the Merger Sub or any Target Fund shareholder with respect to any asset (including, without limitation, any stock held in a passive foreign investment company as defined in Section 1297(a) of the Code) as to which any 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, (2) the effect of the Merger under the alternative minimum tax imposed under Section 55 of the Code on a direct or indirect shareholder of a Target Fund that is a corporation, and (3) any other federal tax issues (except those set forth above) and all state, local or non-U.S. tax issues of any kind.

Each opinion will be based on certain factual representations and customary assumptions. The opinion will rely on such representations and will assume the accuracy of such representations. If such representations and assumptions are incorrect, the Merger may not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and the Target Fund and Target Fund shareholders may recognize taxable gain or loss as a result of the Merger.

Opinions of counsel are not binding upon the IRS or the courts and there can be no assurance that the IRS or a court will concur on all or any of the issues discussed above. If the Merger occurs but the IRS or the courts

42

determine that the Merger does not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, the Target Fund may recognize gain or loss on the transfer of its assets to the Acquiring Fund and/or the deemed distribution of Acquiring Fund shares to its shareholders and each shareholder of the Target Fund would recognize taxable gain or loss equal to the difference between its basis in its Target Fund shares and the fair market value of the shares of the Acquiring Fund it receives.

If a Target Fund common shareholder receives cash in lieu of a fractional Acquiring Fund common share, the shareholder will be treated as having received the fractional Acquiring Fund common share pursuant to the Merger and then as having sold that fractional Acquiring Fund common share for cash. As a result, each such Target Fund common 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 common share. 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 Merger, the holding period for the shares (including the holding period of Target Fund shares surrendered therefor if the Target Fund shares were held as capital assets at the time of the Merger) 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, the Target Fund will declare a distribution to its common shareholders, which together with all other distributions to shareholders made with respect to the taxable year in which the Merger occurs and all prior taxable years, will have the effect of distributing to such shareholders all its net investment income and realized net capital gains (after reduction by any available capital loss carryforwards and excluding any net capital gain on which the Target Fund paid federal income tax), if any, through the Closing Date of the Merger. To the extent distributions are attributable to ordinary taxable income or capital gains, the distribution will be taxable to shareholders who are subject to federal income tax. 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’s proportionate share of the total distributions paid by the Fund with respect to the year. Additional distributions may be made if necessary. For the Acquiring Fund, 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 Fund’s dividend reinvestment plan. The tax character of dividends and distributions (e.g., as consisting of exempt interest, ordinary income and capital gain) will be the same for federal income tax purposes whether received in cash or additional shares.

After the Merger, the Acquiring Fund’s ability to use the Target Fund’s or the Acquiring Fund’s realized and unrealized pre-Merger 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 tax sooner, or pay more federal income tax, than they would have had the Merger 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 Merger and the amount of unrealized capital gains in the Funds at the time of the Merger.

The table below sets forth, as of May 31, 2023 (the Fund’s tax year end), the Target Fund’s unused capital loss carryforwards available for federal income tax purposes to be applied against future capital gains, if any.

|  | Target Fund |
Not subject to expiration: |  |  |  |
Short-Term |  | $ | 4,991,192 |
Long-Term |  | $ | 6,903,838 |
Total |  | $ | 11,895,030 |

The table below sets forth, as of October 31, 2022 (the Fund’s tax year end), the Acquiring Fund’s unused capital loss carryforwards available for federal income tax purposes to be applied against future capital gains, if any.

43

|  | Acquiring Fund |
Not subject to expiration(1): |  |  |  |
Short-Term |  | $ | 132,915,237 |
Long-Term |  | $ | 90,248,489 |
Total |  | $ | 223,163,726 |

(1) | The Acquiring Fund’s ability to use a portion of these capital loss carryforwards is subject to limitation under the Code and related regulations.

In addition, the shareholders of the Target Fund will receive a proportionate share of any taxable income and gains (after the application of any available capital loss carryforwards) realized by the Acquiring Fund and not distributed to its shareholders prior to the closing of the Merger when such income and gains are eventually distributed by the Acquiring Fund. To the extent the Acquiring Fund sells portfolio investments after the Merger, the Acquiring Fund may recognize gains or losses (including any built-in gain in the portfolio investments of the Target Fund or the Acquiring Fund that was unrealized at the time of the Merger), which also may result in taxable distributions to shareholders holding shares of the Acquiring Fund, including former Target Fund shareholders who hold Acquiring Fund shares after the Merger. As a result, shareholders of the Target Fund and the Acquiring Fund may receive a greater amount of taxable distributions than they would have had the Merger not occurred.

The foregoing is intended to be only a summary of the principal federal income tax consequences of the Merger and should not be considered to be tax advice. This description of the federal income tax consequences of the Merger is made without regard to the particular facts and circumstances of any shareholder. There can be no assurance that the IRS or a court will concur on all or any of the issues discussed above. Shareholders are urged to consult their own tax advisers as to the specific consequences to them of the Merger, including without limitation the federal, state, local, and non-U.S. tax consequences with respect to the foregoing matters and any other considerations that may be applicable to them.

Shareholder Approval

The Merger is required to be approved by the affirmative vote of the holders of a majority (more than 50%) of the Target Fund’s outstanding common shares and preferred shares entitled to vote on the matter, voting together as a single class, and by the affirmative vote of the holders of a majority (more than 50%) of the Target Fund’s outstanding preferred shares entitled to vote on the matter, voting together as a single class. The Merger 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 together as a single class. Holders of the Target Fund’s preferred shares are being solicited separately on the foregoing proposal through a separate proxy statement and not through this Joint Proxy Statement/Prospectus.

Abstentions and broker non-votes, if any, will have the same effect as a vote against the approval of the Merger. Broker non-votes are shares held by brokers or nominees, typically in “street name,” as to which (1) instructions have not been received from the beneficial owners or persons entitled to vote and (2) the broker or nominee does not have discretionary voting power on a particular matter. Because the Target Fund’s common shareholders are being asked to vote on both Proposals Nos. 1 and 2, there may be broker non-votes received with respect to Proposal No. 1 at the Target Fund’s Meeting. Because Proposal No. 1 is a non-routine matter and the sole proposal at the Acquiring Fund Meeting, it is expected that there will be no broker non-votes at that Meeting.

Preferred shareholders of the Funds 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. Because the 1940 Act makes no distinction between a plan of reorganization that has an

44

adverse effect as opposed to a materially adverse effect, the Funds are seeking approval of the Agreement by the holders of their preferred shares.

The closing of the Merger is subject to the satisfaction or waiver of certain closing conditions, which include customary closing conditions. In order for the Merger to occur, all requisite shareholder approvals must be obtained at the Meetings, and certain other consents, confirmations and/or waivers from various third parties, including the liquidity providers and/or certain purchasers of the outstanding preferred shares of the Funds, must also be obtained. Because the closing of the Merger is contingent upon the Target Fund and the Acquiring Fund obtaining such shareholder approvals and satisfying (or obtaining the waiver of) other closing conditions, it is possible that the Merger will not occur even if shareholders of a Fund entitled to vote approve the Merger and a Fund satisfies all of its closing conditions if the other Fund does not obtain its requisite shareholder approvals or satisfy (or obtain the waiver of) its closing conditions. If the Merger is not consummated, the Board of the Target Fund may take such actions as it deems in the best interests of the Fund, including conducting additional solicitations with respect to the Merger proposal or continuing to operate the Target Fund as a standalone fund.

The Funds believe that their respective preferred shares are held by a small number of 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, the approval by a Fund’s preferred shareholders required for the Merger to occur may turn on the exercise of voting or consent rights by such particular shareholder(s) and its or their determination as to the favorable view of the Merger with respect to its or their interests. The Funds exercise no influence or control over the determinations of such shareholders with respect to the Merger; there is no guarantee that such shareholders will vote to approve the Merger proposal.

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

General

As a general matter, the common shares of the Acquiring Fund and the Target Fund have equal voting rights and equal rights with respect to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of their Fund and have no preemptive, conversion or exchange rights, except as the Trustees may authorize, or rights to cumulative voting. Holders of whole common shares of each Fund are entitled to one vote per share on any matter on which they are entitled to vote, while each fractional share entitles its holder to a proportional fractional vote. Furthermore, the provisions set forth in each Fund’s declaration of trust and by-laws include, among other things, substantially identical super-majority voting provisions, as described under “Additional Information About the Acquiring Fund—Certain Provisions in the Acquiring Fund’s Declaration of Trust and By-Laws.” The full text of each Fund’s declaration of trust and by-laws are on file with the SEC and may be obtained as described on page [●].

The Acquiring Fund’s declaration of trust authorizes an unlimited number of common shares, par value $0.01 per share. If the Merger is consummated, the Acquiring Fund will issue additional common shares on the Closing Date to the common shareholders of the Target Fund based on the relative per share net asset value of the Acquiring Fund and the Target Fund, in each case as of the Valuation Time. The value of a Fund’s net assets will be calculated net of the liquidation preference (including accumulated and unpaid dividends) of all of the Fund’s outstanding preferred shares.

The terms of the Acquiring Fund common shares to be issued pursuant to the Merger 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 dissolution, liquidation or winding up of the affairs of the Acquiring Fund. 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 “Summary Description of Massachusetts Business Trusts.”

45

Distributions on Common Shares

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 current policy, which may be changed by its Board, is to pay regular monthly dividends out of its net investment income 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 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 gains 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 gains (the excess of net long-term capital gains over net short-term capital losses) otherwise allocable to shareholders and pay federal income tax on the retained gain. As provided under federal income tax law, shareholders will include their share of the retained net capital gains in their income for the year as a long-term capital gain (regardless of their holding period in the shares) and will be entitled to a federal income tax credit or refund for the federal income tax deemed paid on their behalf by the Acquiring Fund. See “Additional Information About the Acquiring Fund—Federal Income Tax Matters Associated with Investment in the Acquiring Fund” below and “Federal Income Tax Matters” in the Merger 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 outstanding common shares unless all accumulated dividends on preferred shares have been paid and unless the asset coverage, as defined in the 1940 Act, with respect to its 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

The terms of the dividend reinvestment plan (the “Plan”) for the Acquiring Fund and the Target Fund are identical. 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 Computershare Trust Company, N.A. (the “Plan Agent”) in additional common shares under the Plan. You may elect to participate in the Plan by contacting Nuveen Investor Services at (800) 257-8787. If you do not participate, you will receive all distributions in cash paid by check mailed directly to you or your brokerage firm by Computershare Inc. and the Plan 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 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 NYSE or elsewhere, 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,

46

| 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 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; or

| (3) | 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 Acquiring 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. Upon a sale of your shares, the Acquiring Fund (or its administrative agent) may be required to report to the IRS and furnish to you cost basis and holding period information for the Acquiring Fund’s shares purchased on or after January 1, 2012 (“covered shares”).

For shares of the Acquiring Fund held in the Plan, you are permitted to elect from among several permitted cost basis methods. In the absence of an election, the Plan will use first-in first-out methodology for tracking and reporting your cost basis on covered shares as its default cost basis method. The cost basis method you use may not be changed with respect to a sale of shares after the settlement date of the sale. You should consult with your tax advisors to determine the best permitted cost basis method for your tax situation and to obtain more information about how the cost basis reporting rules apply to you.

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 on such dividends and distributions.

If you hold your common shares with a brokerage firm that does not participate in the Plan, you will not be able to participate in the Plan and any dividend reinvestment may be effected on different terms than those described above. Consult your financial advisor for more information.

The Acquiring Fund reserves the right to amend or terminate the Plan if in the judgment of the Board the change is warranted. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. Additional information about the Plan may be obtained by writing to Computershare, P.O. Box 505000, Louisville, Kentucky 40233-5000, or by calling (800) 257-8787.

On [●], 2023, the closing sale prices of the Target Fund and the Acquiring Fund common shares were $[●] and $[●], respectively. These prices represent [premiums/discounts] to net asset value for the Target Fund and the Acquiring Fund of [●]% and [●]%, respectively.

Common shares of each Fund have historically traded at a 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 Merger, or what the extent of any such premium or discount might be.

Affiliated Brokerage and Other Fees

Neither the Target Fund nor the Acquiring Fund paid brokerage commissions within the last fiscal year to (i) any broker that is an affiliated person of such Fund or an affiliated person of such person, or (ii) any broker an affiliated person of which is an affiliated person of such Fund, the Adviser, or the Sub-Adviser of such Fund.

During the last fiscal year, neither the Target Fund nor the Acquiring Fund made any material payments to the Adviser or Sub-Adviser or any affiliated person of the Adviser or Sub-Adviser for services provided to the Target Fund and Acquiring Fund (other than pursuant to their respective Investment Management Agreements).

Description of VRDP Shares to be Issued by the Acquiring Fund

If the Merger takes place, the Acquiring Fund will issue VRDP Shares (the “New VRDP Shares”) pursuant to the Agreement if VRDP Shares of the Target Fund are outstanding immediately prior to the Closing.

The terms of the New VRDP Shares will be substantially similar, as of the time of the closing of the Merger, to the terms of the VRDP Shares of the Target Fund outstanding immediately prior to the closing of the Merger. However, because of the Acquiring Fund’s policy of investing in a nationally diversified portfolio of municipal securities, the terms of the New VRDP Shares will not include a provision, currently applicable to the Target Fund VRDP Shares, that generally would require an additional payment to holders subject to Massachusetts income taxation in the event the Target Fund was required to allocate capital gains and/or ordinary income to a given month’s distribution in order to make such distribution equal, on an after-tax basis, to the amount of the distribution if it was excludable from Massachusetts income taxation (in addition to federal income taxation). The aggregate liquidation preference of the New VRDP Shares to be received in the Merger, if any, will equal the aggregate liquidation preference of the Target Fund VRDP Shares held immediately prior to the closing of the Merger. The economic terms of any New VRDP Shares likely will not be the same as the terms of the outstanding VRDP Shares and other outstanding preferred shares of the Acquiring Fund. The number of VRDP Shares of the Target Fund currently outstanding may change prior to the Merger due to market or other conditions. See “Additional Information About the Acquiring Fund—Description of Outstanding Acquiring Fund VRDP Shares.”

Holders of the New VRDP Shares will be entitled to receive cash dividends when, as and if declared by the Acquiring Fund’s Board. The amount of dividends per New VRDP Share will equal the sum of dividends accumulated for each day but not yet paid during the relevant monthly dividend period. The amount of dividends will be calculated based on an index rate equal to the SIFMA Municipal Swap Index, a percentage of the one-month term Secured Overnight Financing Rate (SOFR) or another benchmark rate plus an applicable spread. The applicable spread will be subject to adjustment in certain circumstances, including a change in the credit rating assigned to the New VRDP Shares. In no circumstances may the dividend rate exceed 15% per annum with respect to any dividend rate period.

The outstanding Series 1 VRDP Shares of the Target Fund have a final mandatory redemption date of March 1, 2047, subject to earlier redemption or repurchase. The New VRDP Shares will have the same final mandatory redemption date as the Target Fund VRDP Shares. The VRDP Shares of the Target Fund are (and the New VRDP Shares are expected to be) in a “Special Rate Period” (Adjustable Rate) in which the dividend is currently a variable rate determined by reference to an index rate plus an applicable spread. So long as the VRDP Shares are “Adjustable Rate,” the fund and the beneficial owner or owners of the VRDP Shares may agree from time to time to adjust the dividend rate and other economic terms. During a Special Rate Period, the VRDP Shares are not remarketed by a remarketing agent, and are not subject to optional or mandatory tender events or supported by a liquidity provider and are not subject to remarketing fees or liquidity fees.

The New VRDP Shares will be subject to optional and mandatory redemption in certain circumstances. The Acquiring Fund will be obligated to redeem the New VRDP Shares on the applicable final mandatory redemption date, unless earlier redeemed or repurchased by the Acquiring Fund, at a redemption price per share equal to the liquidation preference per share ($100,000) plus any accumulated but unpaid dividends (whether or not earned or declared). New VRDP Shares also will be redeemable in whole at any time or in part from time to time at the option of the Acquiring Fund at a redemption price per share equal to the liquidation preference per share plus any accumulated but unpaid dividends (whether or not earned or declared).

During the Special Rate Period for the New VRDP Shares, 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 is necessary to achieve compliance with such requirements. Also, during the Special Rate Period for the New

49

VRDP Shares, the Acquiring Fund will be obligated to redeem all of the outstanding New VRDP Shares in the event a Special Rate Period transition is initiated and a failed transition occurs, if such failure is not cured within the applicable cure period.

The New VRDP Shares will be 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 New VRDP Shares will have equal priority with each other and the other preferred shares of the Acquiring Fund, including the Acquiring Fund’s outstanding AMTP Shares, MFP Shares and VRDP Shares and any other preferred shares that the Acquiring Fund may issue in the future, 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.

Summary Description of Massachusetts Business Trusts

The following description is based on relevant provisions of applicable Massachusetts law and each Fund’s governing documents. This summary does not purport to be complete and we refer you to applicable Massachusetts law and each Fund’s operative documents.

General. Each Fund is a Massachusetts business trust. A fund organized as a Massachusetts business trust is governed by the trust’s declaration of trust or similar instrument, and its by-laws (its “governing documents”). Massachusetts law allows the trustees of a business trust to set the terms of a fund’s governance in its governing documents. 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 fund’s governing documents.

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 of trust and by-laws 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 or newer statutory trust laws, such as those of Delaware, provide.

Shareholders of a Massachusetts business trust 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 of each Fund 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. However, courts in Massachusetts have recognized limitations of a trustee’s personal liability in contract actions for the obligations of a trust contained in the trust’s declaration of trust, and declarations of trust 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 of each Fund contains such provisions.

The Funds

Each Fund is organized as a Massachusetts business trust and is governed by its declaration of trust and by-laws. Under the declaration of trust of each Fund, 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, the 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

50

determinations will be so binding. The by-laws of each Fund provide that each shareholder of the Fund, by virtue of having become a shareholder, shall be held to have expressly assented and agreed to be bound by the terms of the Fund’s governing documents. The Funds’ declarations of trust are substantially the same, and the Funds have adopted the same by-laws. The following is a summary of some of the key provisions of the Funds’ governing documents.

Shareholder Voting. The declaration of trust of each Fund limits shareholder voting to certain enumerated matters, including certain amendments to the declaration of trust, the election of trustees if required by the 1940 Act, the merger or consolidation of the Fund with any corporation or a reorganization or sales of assets in certain circumstances and matters required to be voted on by the 1940 Act, or, for the Target Fund and the Acquiring Fund, a recapitalization of the Fund (under certain circumstances).

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 holders of a majority (more than 50%) of the voting power of the shares of beneficial interest of the Fund entitled to vote at a meeting will constitute a quorum for the transaction of business. Notwithstanding the foregoing, when the holders of preferred shares are entitled to elect any of a Fund’s trustees by class vote of such holders, the holders of thirty-three and one-third percent (33 1/3%) of the preferred shares entitled to vote at a meeting shall constitute a quorum for the purpose of such an election. Unless other voting provisions contained in the Fund’s governing documents or the 1940 Act apply, the affirmative vote of the holders of a majority (more than 50%) 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. The governing documents require a super-majority vote in certain circumstances 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 and that the affirmative vote of a majority (more than 50%) of the shares outstanding and entitled to vote is required to elect trustees in a “contested election” (i.e., an election in which the number of trustees nominated exceeds the number of trustees to be elected), but that a plurality vote applies in an uncontested election.

The by-laws of each Fund provide that common shares held by a shareholder who obtains beneficial ownership of common shares in a “Control Share Acquisition” shall have the same voting rights as other common shares only to the extent authorized by the Fund’s shareholders (the “Control Share Provision”). Such authorization shall require the affirmative vote of the holders of a majority (more than 50%) of the shares of the Fund entitled to vote in the election of trustees, excluding Interested Shares. Interested Shares include shares held by Fund officers and any person who has acquired common shares in a Control Share Acquisition. The by-laws define a “Control Share Acquisition,” subject to various conditions and exceptions, generally to mean an acquisition of common shares that would give the beneficial owner, upon the acquisition of such shares, the ability to exercise voting power, but for the Control Share Provision, in the election of trustees (except for any elections of trustees by holders of preferred shares voting as a separate class) in any one of the following ranges: (i) one-tenth or more, but less than one-fifth of all voting power; (ii) one-fifth or more, but less than one-third of all voting power; (iii) one-third or more, but less than a majority of all voting power; or (iv) a majority or more of all voting power. For this purpose, all common shares acquired by a person within ninety days before or after the date on which such person acquires shares that result in a Control Share Acquisition, and all common shares acquired by such person pursuant to a plan to make a Control Share Acquisition, shall be deemed to have been acquired in the same Control Share Acquisition. Subject to various conditions and procedural requirements, including the delivery of a “Control Share Acquisition Statement” to the Fund setting forth certain required information, a shareholder who obtains or proposes to obtain beneficial ownership of common shares in a Control Share Acquisition generally may request a vote of shareholders to approve the authorization of voting rights of such shareholder with respect to such shares. See “General Information—Additional Information About the Solicitation” at page [●] for a description of certain legal matters with respect to the Control Share Provision.

Shareholder Meetings. Meetings of shareholders may be called by the trustees and must be called upon the written request of shareholders entitled to cast at least 10% of all votes entitled to be cast at the meeting.

51

Shareholder requests for special meetings are subject to various requirements under each Fund’s by-laws, including as to the specific form of, and information required in, a shareholder’s request to call such a meeting. A shareholder may request a special meeting only to act on a matter upon which such shareholder is entitled to vote, and shareholders may not request special meetings for the purpose of electing trustees.

The by-laws of each Fund authorize the trustees or the chair of a shareholder meeting to adopt rules, regulations and procedures appropriate for the proper conduct of the meeting, which may include (i) the establishment of an agenda or order of business for the meeting; (ii) the determination of when the polls shall open and close for any given matter to be voted on by the shareholders present or represented at the meeting; (iii) rules and procedures for maintaining order at the meeting and the safety of those present; (iv) limitations on attendance at and participation in the meeting by other than shareholders, their duly authorized and constituted proxies or such other persons as the chair of the meeting shall determine; (v) restrictions on entry to the meeting after the time fixed for the commencement thereof; (vi) limitations on the time allotted to questions or comments by shareholders; and (vii) the extent to which, if any, other participants are permitted to speak.

The by-laws of each Fund establish qualification criteria applicable to prospective trustees and generally require that advance notice be given to the Fund in the event a shareholder desires to nominate a person for election to the Board or to transact any other business at a meeting of shareholders. Any notice by a shareholder must be accompanied by certain information as required by the by-laws. No shareholder proposal will be considered at any meeting of shareholders of a Fund if such proposal does not satisfy all applicable requirements set forth in the by-laws, and, unless required by applicable law, no matter shall be considered at or brought before any meeting of shareholders unless such matter has been deemed a proper matter for shareholder action by the chair of the meeting, the Chief Administrative Officer of the Fund or at least sixty-six and two-thirds percent (66 2/3%) of the Fund’s trustees.

Election and Removal of Trustees. The declaration of trust of each Fund provides that the trustees determine the size of the Board, subject to a minimum and a maximum number. 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 be removed only for cause and only 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. The by-laws of each Fund establish qualification requirements applicable to any person who is recommended, nominated, elected, appointed, qualified or seated as a trustee.

Pursuant to each Fund’s by-laws, the Fund’s Board 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 in addition to the two trustees elected by the holders of the Fund’s preferred shares. The staggered board structure could delay for up to two years the election of a majority of the Board of each Fund. The board structure of the Acquiring Fund will remain in place following the closing of the Merger.

Issuance of Shares. Under the declaration of trust of each 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 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 Governing Documents. 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

52

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, if any, entitled to vote, 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. Each Fund’s by-laws may be amended or repealed, or new by-laws may be adopted, by a vote of a majority of the trustees. The by-laws of each Fund may not be amended by shareholders.

Shareholder, Trustee and Officer Liability. The declaration of trust of each Fund provides that shareholders have no personal liability for the acts or obligations of the Fund and requires 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 reason. In addition, each declaration of trust provides that the Fund will assume the defense of any claim against a shareholder for personal liability at the request of the shareholder. Similarly, each 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 such trustee’s, officer’s or employee’s bad faith, willful misfeasance, gross negligence or reckless disregard for his or her duty. Each 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. Each declaration of trust also provides that the trustees may rely in good faith on expert advice.

Forum Selection. Each Fund’s by-laws provide that, unless the Fund consents in writing to the selection of an alternative forum, and except for certain claims brought under the federal securities laws, the sole and exclusive forum for any shareholder or group of shareholders to bring (i) any derivative action or proceeding brought on behalf of the Fund, (ii) any action asserting a claim for breach of any duty owed by a trustee or officer or other employee of a Fund to the Fund or to the Fund’s shareholders, (iii) any action asserting a claim arising pursuant to Massachusetts business trust law or the Fund’s governing documents, and (iv) any other action asserting a claim governed by the internal affairs doctrine, shall be within the United States District Court for the District of Massachusetts (Boston Division) or, to the extent such court does not have jurisdiction, the Business Litigation Session of the Massachusetts Superior Court in Suffolk County. Each Fund’s by-laws further provide that in any such covered action there is no right to a jury trial and the right to a jury trial is expressly waived to the fullest extent permitted by law.

Derivative and Direct Claims of Shareholders. Each Fund’s by-laws contain provisions regarding derivative and direct claims of shareholders. Massachusetts has what is commonly referred to as a “universal demand statute,” which has been applied by courts to Massachusetts trusts like the Funds, and which requires that a shareholder make a written demand on the board, requesting the board to bring an action, before the shareholder is entitled to bring or maintain a derivative action in the right of or name of or on behalf of the trust. Under the Massachusetts statute, a shareholder whose demand has been refused by the board may bring the claim only if the shareholder demonstrates to a court that the board’s decision not to pursue the requested action was not a good faith exercise of their business judgment on behalf of the company. The by-laws of each Fund largely incorporate the substantive elements of the Massachusetts statute and establish procedures for shareholders to bring derivative actions and for the Board to consider shareholder demands that the Fund commence a suit. In addition, the by-laws of each Fund distinguish direct actions from derivative claims and prohibit the latter from being brought directly by a shareholder.

D. | ADDITIONAL INFORMATION ABOUT THE INVESTMENT POLICIES

Comparison of the Investment Objectives and Policies of the Acquiring Fund and the Target Fund

General

The Funds have similar investment objectives, policies, and risks, but there are differences. The Target Fund is a state-specific municipal fund that seeks to provide current income exempt from regular federal income tax and the income tax of a single state. In contrast, the Acquiring Fund is a national municipal fund that seeks to provide current income exempt from regular federal income tax and the federal alternative minimum tax applicable to individuals.

The Target Fund’s primary investment objective is to provide, through investment in a professionally managed portfolio of tax-exempt municipal obligations, current income exempt from both regular federal income taxes and Massachusetts personal income taxes, consistent with the Fund’s investment policies. The secondary investment objective of the Target Fund is the enhancement of portfolio value relative to the Massachusetts municipal bond market through investments in tax-exempt Massachusetts municipal obligations that, in the opinion of the Adviser, are underrated or undervalued or that represent municipal market sectors that are undervalued. As a fundamental policy, under normal circumstances, the Target Fund will invest at least 80% of its Assets in municipal securities and other related investments the income from which is exempt from regular federal and Massachusetts income taxes. As a non-fundamental policy, under normal circumstances, the Target Fund will invest at least 80% of its Managed Assets in securities that at the time of investment are investment grade quality. A security is considered investment grade quality if it is rated within the four highest letter grades (Baa or BBB or better) by at least one NRSRO that rates such security (even if it is rated lower by another), or if it is unrated by any NRSRO but judged to be of comparable quality by the Target Fund’s sub-adviser. Under normal circumstances, the Target 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 by any NRSRO but judged to be of comparable quality by the Target Fund’s sub-adviser. No more than 10% of the Target 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 Target Fund’s sub-adviser.

The Acquiring Fund’s investment objectives are to provide current income exempt from regular federal income tax and the federal alternative minimum tax applicable to individuals, and to enhance portfolio value relative to the municipal bond market by investing in tax-exempt municipal securities that the Adviser believes are underrated or undervalued or that represent municipal market sectors that are undervalued. As a fundamental investment policy, under normal circumstances, the Acquiring Fund will invest at least 80% of its Assets in municipal securities and other related investments the income from which is exempt from regular federal income taxes. Additionally, as a fundamental investment policy, under normal circumstances, the Acquiring Fund will invest at least 80% of its Assets in a portfolio of securities the income from which is exempt from the federal alternative minimum tax applicable to individuals. As a non-fundamental investment policy, under normal circumstances, the Acquiring Fund will invest 100% of its Managed Assets in municipal securities and other related investments the income from which is exempt from the federal alternative minimum tax applicable to individuals at the time of purchase. As a non-fundamental policy, under normal circumstances, the Acquiring Fund may invest up to 35% of its Managed Assets in securities rated, at the time of investment, below the three highest grades (Baa or BBB or lower) by at least one NRSRO, which includes below investment grade securities or unrated securities judged to be of comparable quality by the Fund’s sub-adviser. The Acquiring Fund may invest in distressed securities but may not invest in the securities of an issuer which, at the time of investment, is in default on its obligations to pay principal or interest thereon when due or that is involved in a bankruptcy proceeding (i.e., rated below C-, at the time of investment); provided, however, that the Fund’s sub-adviser may determine that it is in the best interest of shareholders in pursuing a workout arrangement with issuers of defaulted securities to make loans to the defaulted issuer or another party, or purchase a debt, equity or other interest from the defaulted issuer or another party, or take other related or similar steps involving the investment of additional monies, but only if that issuer’s securities are already held by the Fund.

54

Note that (1) each Fund’s investment objectives; (2) the Acquiring Fund’s policy to invest, under normal circumstances, at least 80% of its Assets in municipal securities and other related investments the income from which is exempt from regular federal income taxes; (3) the Acquiring Fund’s policy to invest, under normal circumstances, at least 80% of its Assets in a portfolio of securities the income from which is exempt from the federal alternative minimum tax applicable to individuals; and (4) the Target Fund’s policy to invest, under normal circumstances, at least 80% of its Assets in municipal securities and other related investments the income from which is exempt from regular federal and Massachusetts income taxes may not be changed without the approval of the holders of a majority of the outstanding common shares and preferred shares voting together as a single class, and the approval of the holders of a majority of the outstanding preferred shares, voting separately as a single class. When used with respect to particular shares of a Fund, a “majority of the outstanding” shares means (1) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares are present in person (including participation by means of remote or “virtual” communication) or represented by proxy, or (2) more than 50% of the shares, whichever is less.

Investment Policies of the Target Fund

As a fundamental policy, under normal circumstances, the Target Fund will invest at least 80% of its Assets in municipal securities and other related investments the income from which is exempt from regular federal and Massachusetts income taxes.

Under normal circumstances:

| • |  | The Target Fund will invest at least 80% of its Managed Assets in securities that at the time of investment are investment grade quality. A security is considered investment grade quality if it is rated within the four highest letter grades (Baa or BBB or better) by at least one NRSRO that rates such security (even if it is rated lower by another), or if it is unrated by any NRSRO but judged to be of comparable quality by the Fund’s sub-adviser.

| • |  | The Target 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 by any NRSRO but judged to be of comparable quality by the Fund’s sub-adviser.

| • |  | No more than 10% of the Target 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 sub-adviser.

| • |  | The Target Fund may invest up to 20% of its Managed Assets in municipal securities that pay interest that is taxable under the federal alternative minimum tax applicable to individuals.

| • |  | The Target Fund may invest up to 15% of its net assets in inverse floating rate securities.

| • |  | The Target Fund will generally maintain an investment portfolio with an overall weighted average maturity of greater than 10 years.

Investment Policies of the Acquiring Fund

As a fundamental investment policy, under normal circumstances, the Fund will invest at least 80% of its Assets in municipal securities and other related investments the income from which is exempt from regular federal income taxes. Additionally, as a fundamental policy, under normal circumstances, the Acquiring Fund will invest at least 80% of its Assets in a portfolio of securities, the income from which is exempt from the federal alternative minimum tax applicable to individuals at the time of purchase.

As a non-fundamental policy, under normal circumstances, the Acquiring Fund will invest 100% of its Managed Assets in municipal securities and other related investments the income from which is exempt from the federal alternative minimum tax applicable to individuals at the time of purchase.

55

Additionally, as a non-fundamental policy, the Fund:

| • |  | May invest up to 35% of its Managed Assets in securities rated, at the time of investment, below the three highest grades (Baa or BBB or lower) by at least one NRSRO which includes below-investment-grade securities, or unrated securities judged to be of comparable quality by the Fund’s sub-adviser.

| • |  | May invest in distressed securities but may not invest in the securities of an issuer which, at the time of investment, is in default on its obligations to pay principal or interest thereon when due or that is involved in a bankruptcy proceeding (i.e., rated below C-, at the time of investment); provided, however, that the Fund’s sub-adviser may determine that it is in the best interest of shareholders in pursuing a workout arrangement with issuers of defaulted securities to make loans to the defaulted issuer or another party, or purchase a debt, equity or other interest from the defaulted issuer or another party, or take other related or similar steps involving the investment of additional monies, but only if that issuer’s securities are already held by the Fund.

| • |  | May invest up to 15% of its Managed Assets in inverse floating rate securities.

| • |  | The Acquiring Fund may not enter into a futures contract or related options or forward contracts if more than 30% of the Fund’s Managed Assets would be represented by futures contracts or more than 5% of the Fund’s Managed Assets would be committed to initial margin deposits and premiums on futures contracts or related options.

| • |  | The Acquiring Fund will generally maintain an investment portfolio with an overall weighted average maturity of greater than 10 years.

Use of Leverage

Each Fund uses leverage to pursue its investment objectives. The Funds may source leverage through a number of methods including the issuance of preferred shares and portfolio investments that have the economic effect of leverage, including the issuance of inverse floating rate securities.

The Acquiring Fund may also enter into reverse repurchase agreements (effectively a secured borrowing) and borrowings (subject to certain investment restrictions).

Pursuant to its fundamental policy, the Target Fund may not issue senior securities, as defined in the 1940 Act, other than preferred shares. Additionally, as a fundamental policy, the Target Fund may not borrow money, except from banks for temporary or emergency purposes, or to repurchase its shares, and then only in an amount not exceeding one-third of the value of the Target Fund’s total assets including the amount borrowed.

Temporary Defensive Positions

During temporary defensive periods (e.g., times when, in the Target Fund’s investment adviser’s and/or the Target Fund’s sub-adviser’s opinion, temporary imbalances of supply and demand or other temporary dislocations in the tax-exempt bond market adversely affect the price at which long-term or intermediate-term municipal securities are available), the Target Fund may invest up to 100% of its net assets in cash or cash equivalents, short-term investments or municipal bonds and deviate from its investment policies including the Target Fund’s 80% names rule policy. Also, during these periods, the Target Fund may not achieve its investment objectives.

During temporary defensive periods or in order to help keep the Acquiring Fund’s assets fully invested, including during the period within which the net proceeds of an offering of securities are first being invested, the Acquiring Fund may deviate from its investment policies and objectives. During such periods, the Acquiring Fund may invest any percentage of its Managed Assets in short-term investments, including high quality, short-term debt securities that may be either tax-exempt or taxable. The Acquiring Fund may not achieve its investment objectives during such periods.

56

Portfolio Investments

Municipal Securities

General. The Acquiring 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 both regular federal income tax and 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 and possessions to finance or refinance public projects such as roads, schools, and water supply systems. Municipal securities may also be issued on behalf of private entities or 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 of the later issuance of 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 Acquiring Fund.

The Acquiring Fund may invest in municipal bonds issued by U.S. territories and possessions (such as Puerto Rico or Guam) the income from which is exempt from regular federal income tax. 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 securities 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.

Tobacco Settlement Bonds. The Acquiring Fund may invest in tobacco settlement bonds, which are municipal securities that are backed solely by expected revenues to be derived from lawsuits involving tobacco related deaths and illnesses which were settled between certain states and U.S. tobacco companies. Tobacco settlement bonds are secured by an issuing state’s proportionate share in the Master Settlement Agreement (“MSA”). The MSA is an agreement, reached out of court in November 1998 between 46 states and nearly all of the U.S. tobacco manufacturers. The MSA provides for annual payments in perpetuity by the manufacturers to the states in exchange for releasing all claims against the manufacturers and a pledge of no further litigation. Tobacco manufacturers pay into a master escrow trust based on their market share, and each state receives a fixed percentage of the payment as set forth in the MSA. A number of states have securitized the future flow of those payments by selling bonds pursuant to indentures or through distinct governmental entities created for such purpose. The principal and interest payments on the bonds are backed by the future revenue flow related to the MSA. Annual payments on the bonds, and thus risk to a Fund, are highly dependent on the receipt of future settlement payments to the state or its governmental entity.

The actual amount of future settlement payments is further dependent on many factors, including, but not limited to, annual domestic cigarette shipments, reduced cigarette consumption, increased taxes on cigarettes, inflation, financial capability of tobacco companies, continuing litigation and the possibility of tobacco manufacturer bankruptcy. The initial and annual payments made by the tobacco companies will be adjusted

57

based on a number of factors, the most important of which is domestic cigarette consumption. If the volume of cigarettes shipped in the United States by manufacturers participating in the settlement decreases significantly, payments due from them will also decrease. Demand for cigarettes in the United States could continue to decline due to price increases needed to recoup the cost of payments by tobacco companies. Demand could also be affected by anti-smoking campaigns, tax increases, reduced advertising, and enforcement of laws prohibiting sales to minors; elimination of certain sales venues such as vending machines; and the spread of local ordinances restricting smoking in public places. As a result, payments made by tobacco manufacturers could be negatively impacted if the decrease in tobacco consumption is significantly greater than the forecasted decline. A market share loss by the MSA companies to non-MSA participating tobacco manufacturers would cause a downward adjustment in the payment amounts. A participating manufacturer filing for bankruptcy also could cause delays or reductions in bond payments. The MSA itself has been subject to legal challenges and has, to date, withstood those challenges.

Municipal Leases and Certificates of Participation. The Acquiring Fund 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 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, the Acquiring Fund’s original investment. To the extent that the Acquiring 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 Acquiring Fund will purchase municipal securities representing lease obligations only where the Adviser and/or the Sub-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 Acquiring Fund with the right to a pro rata undivided interest in the underlying municipal securities. In addition, such participations generally provide the Acquiring Fund with the right to demand payment, on not more than seven days’ notice, of all or any part of the 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

58

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. However, an investment in such instruments 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 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. The Fund’s distributions of its interest income from private activity bonds may subject certain investors to the federal alternative minimum tax.

Inverse Floating Rate Securities. The Acquiring Fund may invest in inverse floating rate securities. Inverse floating rate securities 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, commonly referred to as a “tender option bond trust” (“TOB trust”), that holds municipal bonds. The TOB trust typically sells two classes of beneficial interests or securities: floating rate securities (sometimes referred to as short-term floaters or tender option bonds (“TOBs”)), and inverse floating rate securities (sometimes referred to as inverse floaters). Both classes of beneficial interests are represented by certificates or receipts. The floating rate securities have first priority on the cash flow from the municipal bonds held by the TOB trust. In this structure, the floating rate security holders have the option, at periodic short-term intervals, to tender their securities to the trust for purchase and to receive the face value thereof plus accrued interest. The obligation of the trust to repurchase tendered securities is supported by a remarketing agent and by a liquidity provider. As consideration for providing this support, the remarketing agent and the liquidity provider receive 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 trust is not obligated to purchase tendered short-term floaters in the event of certain defaults with respect to the underlying municipal bonds or a significant downgrade in the credit rating assigned to the bond issuer.

As the holder of an inverse floating rate investment, the Acquiring Fund receives the residual cash flow from the TOB trust. Because the holder of the short-term floater is generally assured liquidity at the face value of the security plus accrued interest, the holder of the inverse floater assumes the interest rate cash flow risk and the

59

market value risk associated with the municipal bond deposited into the TOB 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 to the value of the inverse floaters that are issued by the TOB 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 TOB trust are passed through, pro rata, to the holders of the short-term floaters and to the Acquiring Fund as the holder of the associated inverse floaters.

Because any increases in the interest rate on the short-term floaters issued by a TOB trust would reduce the residual interest paid on the associated inverse floaters, and because fluctuations in the value of the municipal bond deposited in the TOB trust would affect only the value of the inverse floater and not the value of the short-term floater issued by the trust so long as the value of the municipal bond held by the trust exceeded the face amount of short-term floaters outstanding, the value of inverse floaters is generally more volatile than that of an otherwise comparable municipal bond held on an unleveraged basis outside a TOB trust. Inverse floaters generally will underperform the market of fixed-rate bonds in a rising interest rate environment (i.e., when bond values are falling), but will tend to outperform the market of fixed-rate bonds when interest rates decline or remain relatively stable. Although volatile in value and return, 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 primarily upon the inverse floater holder’s ability to sell the underlying bonds deposited in the TOB trust at an attractive price.

The Acquiring Fund may invest in inverse floating rate securities issued by TOB trusts in which the liquidity providers have recourse to the Fund pursuant to a separate shortfall and forbearance agreement. Such an agreement would require the Acquiring Fund to reimburse the liquidity provider, among other circumstances, upon termination of the TOB trust for the difference between the liquidation value of the bonds held in the trust and the principal amount and accrued interest due to the holders of floating rate securities issued by the trust. The Acquiring Fund will enter into such a recourse agreement (1) when the liquidity provider requires such a recourse agreement because the level of leverage in the TOB trust exceeds the level that the liquidity provider is willing to support absent such an agreement; and/or (2) to seek to prevent the liquidity provider from collapsing the trust in the event the municipal bond held in the trust has declined in value to the point where it may cease to exceed the face amount of outstanding short-term floaters. In an instance where the Acquiring 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 plus accrued interest thereon.

The Acquiring Fund may invest in both inverse floating rate securities and floating rate securities (as discussed below) issued by the same TOB trust.

Investments in inverse floating rate securities create leverage. The use of leverage creates special risks for common shareholders. See “B. Risk Factors—Inverse Floating Rate Securities Risk.”

Floating Rate Securities. The Acquiring Fund may also invest in short-term floating rate securities, as described above, issued by TOB trusts. 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 other periods of up to one year. Since the tender option feature provides a shorter term than the final maturity or first call date of the underlying municipal bond deposited in the trust, the Acquiring Fund, as the holder of the floating rate securities, relies upon the terms of the remarketing and liquidity agreements with the financial institution that acts as remarketing agent and/or liquidity provider as well as the credit strength of that institution. As further assurance of liquidity, the terms of the TOB 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 TOB 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.

60

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.

Illiquid Securities

The Acquiring 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 be resold only pursuant to Rule 144A under the 1933 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 1933 Act. Where registration is required, the Acquiring Fund 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 Fund may be permitted to sell a security under an effective registration statement. If, during such a period, adverse market conditions were to develop, the Acquiring Fund 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 or its delegate.

When-Issued and Delayed-Delivery Transactions

The Acquiring 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. On such transactions, the payment obligation and the interest rate are fixed at the time the buyer enters into the commitment. Beginning on the date the Acquiring Fund enters into a commitment to purchase securities on a when-issued or delayed-delivery basis, the Fund is required under interpretations 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, at least equal to the amount of the commitment. Income generated by any such assets which provide taxable income for federal income tax purposes is includable in the taxable income of the Acquiring Fund and, to the extent distributed, will be taxable to shareholders. The Acquiring Fund may enter into contracts to purchase municipal 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 cost.

Derivatives

General. The Acquiring Fund may invest in certain derivative instruments in pursuit of its investment objectives. Such instruments include financial futures contracts, swap contracts (including interest rate swaps, credit default swaps and MMD Rate Locks), options on financial futures, options on swap contracts or other derivative instruments. 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 the Acquiring Fund is a seller of a contract, the Fund would be required to pay the par (or other agreed upon) value

61

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, the Acquiring 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, the Acquiring Fund would keep the stream of payments and would have no payment obligations. As the seller, the Acquiring Fund would be subject to investment exposure on the notional amount of the swap. If the Acquiring 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, the Acquiring 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 the Acquiring Fund. Interest rate swaps involve the exchange by the Acquiring 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. The Acquiring 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. An MMD Rate Lock permits the Acquiring Fund to lock in a specified municipal interest rate for a portion of its portfolio to preserve a return on a particular investment or a portion of its portfolio as a duration management technique or to protect against any increase in the price of securities to be purchased at a later date. By using an MMD Rate Lock, the Acquiring Fund can create a synthetic long or short position, allowing the Fund to select what the manager believes is an attractive part of the yield curve. The Acquiring Fund will ordinarily use these transactions as a hedge or for duration or risk management although it is permitted to enter into them to enhance income or gain or to increase the Acquiring Fund’s yield, for example, during periods of steep interest rate yield curves (i.e., wide differences between short term and long term interest rates).

The Adviser and/or the Sub-Adviser may use derivative instruments to seek to enhance return, to hedge some of the risks of the Acquiring 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 and/or the Sub-Adviser will determine to use them for the Acquiring Fund or, if used, that the strategies will be successful.

Limitations on the Use of Futures, Options on Futures and Swaps. The Adviser has claimed, with respect to the Acquiring Fund, the exclusion from the definition of “commodity pool operator” under the CEA provided by CFTC Regulation 4.5 and is therefore not currently subject to registration or regulation as such under the CEA with respect to the Fund. In addition, the Sub-Adviser has claimed the exemption from registration as a commodity trading advisor provided by CFTC Regulation 4.14(a)(8) and is therefore not currently subject to registration or regulation as such under the CEA with respect to the Acquiring Fund. In February 2012, the CFTC announced substantial amendments to certain exemptions, and to the conditions for reliance on those exemptions, from registration as a commodity pool operator. Under amendments to the exemption provided under CFTC Regulation 4.5, if the Acquiring Fund uses futures, options on futures, or swaps other than for bona fide hedging purposes (as defined by the CFTC), the aggregate initial margin and premiums on these positions (after taking into account unrealized profits and unrealized losses on any such positions and excluding the amount by which options that are “in-the-money” at the time of purchase are “in-the-money”) may not exceed 5% of the Fund’s net asset value, or alternatively, the aggregate net notional value of those positions may not exceed 100% of the Fund’s net asset value (after taking into account unrealized profits and unrealized losses on any such positions). The CFTC amendments to Regulation 4.5 took effect on December 31, 2012, and the Acquiring Fund intends to comply with amended Regulation 4.5’s requirements such that the Adviser will not be required to register as a commodity pool operator with the CFTC with respect to the Fund. The Acquiring Fund reserves the right to employ futures, options on futures and swaps to the extent allowed by CFTC regulations in effect from time to

62

time and in accordance with the Fund’s policies. However, the requirements for qualification as a RIC under Subchapter M of the Code may limit the extent to which the Acquiring Fund may employ futures, options on futures or swaps.

Structured Notes

The Acquiring 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 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 Acquiring Fund may invest 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, to the extent permitted by the 1940 Act, the rules and regulations issued thereunder and applicable exemptive orders issued by the SEC. In addition, the Acquiring 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. The Acquiring 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 market. The Acquiring Fund may invest in investment companies that are advised by the Adviser and/or the Sub-Adviser or their affiliates to the extent permitted by applicable law and/or pursuant to rules promulgated by the SEC. As a shareholder in an investment company, the Acquiring Fund will bear its ratable share of that investment company’s expenses and would remain subject to payment of its own management fees with respect to assets so invested. Common shareholders would therefore be subject to duplicative expenses to the extent the Acquiring Fund invests in other investment companies.

The Adviser and/or the Sub-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.

Inter-Fund Borrowing and Lending

The SEC has granted an exemptive order permitting the Nuveen registered open-end and closed-end funds, including the Acquiring Fund, to participate in an inter-fund lending facility whereby those funds may directly lend to and borrow money from each other for temporary purposes (e.g., to satisfy redemption requests or when a sale of securities “fails,” resulting in an unanticipated cash shortfall) (the “Inter-Fund Program”). The closed-end Nuveen funds will participate only as lenders, and not as borrowers, in the Inter-Fund Program because such closed-end funds rarely, if ever, need to borrow cash to meet redemptions. The Inter-Fund Program is subject to a number of conditions, including, among other things, the requirements that

63

(1) no fund may borrow or lend money through the Inter-Fund Program unless it receives a more favorable interest rate than is typically available from a bank or other financial institution for a comparable transaction; (2) no fund may borrow on an unsecured basis through the Inter-Fund Program unless the fund’s outstanding borrowings from all sources immediately after the inter-fund borrowing total 10% or less of its total assets; provided that if the borrowing fund has a secured borrowing outstanding from any other lender, including but not limited to another fund, the inter-fund loan must be secured on at least an equal priority basis with at least an equivalent percentage of collateral to loan value; (3) if a fund’s total outstanding borrowings immediately after an inter-fund borrowing would be greater than 10% of its total assets, the fund may borrow through the inter-fund loan on a secured basis only; (4) no fund may lend money if the loan would cause its aggregate outstanding loans through the Inter-Fund Program to exceed 15% of its net assets at the time of the loan; (5) a fund’s inter-fund loans to any one fund shall not exceed 5% of the lending fund’s net assets; (6) the duration of inter-fund loans will be limited to the time required to receive payment for securities sold, but in no event more than seven days; and (7) each inter-fund loan may be called on one business days’ notice by a lending fund and may be repaid on any day by a borrowing fund. In addition, a Nuveen fund may participate in the Inter-Fund Program only if and to the extent that such participation is consistent with the fund’s investment objective and investment policies. The Board of Trustees of the Nuveen Funds is responsible for overseeing the Inter-Fund Program. The limitations detailed above and the other conditions of the SEC exemptive order permitting the Inter-Fund Program are designed to minimize the risks associated with Inter-Fund Program for both the lending fund and the borrowing fund. However, no borrowing or lending activity is without risk. When a fund borrows money from another fund, there is a risk that the loan could be called on one day’s notice or not renewed, in which case the fund may have to borrow from a bank at a higher rate or take other actions to payoff such loan if an inter-fund loan is not available from another fund. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.

Zero Coupon Bonds

A zero coupon bond is a bond that typically 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, the holder receives the par value of the zero coupon bond, which generates a return equal to 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. This original issue discount (“OID”) approximates the total amount of interest the security will accrue and compound prior to its maturity and reflects the payment deferral and credit risk associated with the instrument. Because zero coupon securities and other OID instruments do not pay cash interest at regular intervals, the instruments’ ongoing accruals require ongoing judgments concerning the collectability of deferred payments and the value of any associated collateral. As a result, these securities may be subject to greater value fluctuations and less liquidity in the event of adverse market conditions than comparably rated securities that pay cash on a current basis. Because zero coupon bonds, and OID instruments generally, allow an issuer to avoid or delay the need to generate cash to meet current interest payments, they may involve greater payment deferral and credit risk than coupon loans and bonds that pay interest currently or in cash. The Acquiring Fund generally will be required to distribute dividends to shareholders representing the income 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, the Acquiring Fund may have to sell other investments, including when it may not be advisable to do so, and use the cash proceeds to make income distributions to its shareholders. For accounting purposes, these cash distributions to shareholders will not be treated as a return of capital.

Further, the Adviser collects management fees on the value of a zero coupon bond or OID instrument attributable to the ongoing noncash accrual of interest over the life of the bond or other instrument. As a result, the Adviser receives nonrefundable cash payments based on such noncash accruals while investors incur the risk that such noncash accruals ultimately may not be realized.

64

Hedging Strategies

The Acquiring Fund may use various investment strategies designed to limit the risk of bond price fluctuations and to preserve capital. These hedging strategies include using 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 and/or the Sub-Adviser, correlate with the prices of the Acquiring Fund’s investments. These hedging strategies may generate taxable income.

Each Board recommends that shareholders vote FOR the approval of the Agreement and Plan of Merger.

PROPOSAL NO. 2—THE ELECTION OF BOARD MEMBERS

(COMMON SHAREHOLDERS OF TARGET FUND ONLY)

Pursuant to the governing documents of the Target Fund, the Fund’s Board is divided into three classes (Class I, Class II and Class III), to be elected by the holders of the outstanding shares to serve until the third succeeding annual meeting of shareholders subsequent to their election or thereafter, in each case until their successors have been duly elected and qualified. In addition, two Board Members are elected annually by the holders of the outstanding preferred shareholders of the Fund. The preferred shareholders of the Target Fund are being solicited to vote on this Proposal No. 2, including the election of such Board Members to be elected by the preferred shareholders of the Target Fund, by means of a separate proxy statement.

Four (4) Board Members are to be elected by holders of common and preferred shares of the Target Fund, voting together as a single class. Current Board Members Lancellotta, Nelson and Toth have been designated as Class II Board Members and are nominees for election at the Annual Meeting to serve for a term expiring at the 2026 annual meeting of shareholders or until their successors have been duly elected and qualified. Current Board Member Young, previously designated as a Class II Board Member, has been designated as a Class I Board Member and is a nominee for election at the Annual Meeting to serve for a term expiring at the 2025 annual meeting of shareholders or until his successor has been duly elected and qualified. Board Members Hunter and Moschner are nominees to be elected by holders of preferred shares for a term expiring at the next annual meeting or until their successors have been duly elected and qualified.

Board Members Evans, Medero, Thornton and Wolff are current and continuing Board Members. Current Board Member Wolff has been designated as a Class I Board Member for a term expiring at the 2025 annual meeting of shareholders or until her successor has been duly elected and qualified. Board Members Evans, Medero and Thornton have been designated as Class III Board Members for a term expiring at the 2024 annual meeting of shareholders or until their successors have been duly elected and qualified.

It is the intention of the persons named in the enclosed proxy to vote the shares represented thereby for the election of the nominees listed in the table below unless the proxy is marked otherwise. Each of the nominees has agreed to serve as a Board Member of the Target Fund if elected. However, should any nominee become unable to serve or for good cause will not serve, the proxies will be voted for substitute nominees, if any, designated by the Target Fund’s present Board.

Class I Board Member Wolff was last elected at the annual meeting of shareholders held on November 18, 2022. Class II Board Members Nelson, Toth and Young were last elected at the annual meeting of shareholders held on November 16, 2020. Board Member Lancellotta was appointed to the Target Fund’s Board as a Class II Board Member effective June 1, 2021. Class III Board Members Evans, Medero and Thornton were last elected at the annual meeting of shareholders held on November 17, 2021. Board Members Hunter and Moschner were last elected at the annual meeting of shareholders held on November 18, 2022.

65

Each of the Board Members and Board Member nominees is not an “interested person,” as defined in the 1940 Act, of the Target Fund or of Nuveen Fund Advisors, LLC (previously defined as “Nuveen Fund Advisors” or the “Adviser”), the investment adviser to the Target Fund, and has never been an employee or director of the Adviser, Nuveen, the Adviser’s parent company, or any affiliate. Accordingly, such Board Members are deemed “Independent Board Members.”

The affirmative vote of a plurality (the greatest number of affirmative votes) of the shares present and entitled to vote at the Meeting will be required to elect each Board Member of the Target Fund. When there are four (4) nominees for election to the Board, as is the case here, a vote by plurality means the four nominees with the highest number of affirmative votes, regardless of the votes withheld for the nominees, will be elected. Because the election of Board Members does not require that a minimum percentage of the Target Fund’s outstanding common shares be voted in favor of any nominee, assuming the presence of a quorum, abstentions and broker non-votes will have no effect on the outcome of the election of the Target Fund’s Board Members. The affirmative vote of a plurality of the Target Fund’s outstanding preferred shares, voting separately, will be required to elect Board Members Hunter and Moschner.

The Board of the Target Fund unanimously recommends that shareholders vote FOR the election of each Board Member nominee.

Board Member Investments in the Funds

In order to create an appropriate identity of interests between Board Members and shareholders, the Boards of Directors/Trustees of the Nuveen funds have adopted a governance principle pursuant to which each Board Member is expected to invest, either directly or on a deferred basis, at least the equivalent of one year of compensation in the funds in the Nuveen fund complex.

(1) | The amounts reflect the aggregate dollar range of equity securities of the number of shares beneficially owned by the Board Member/nominee of the Funds and in all Nuveen Funds overseen by each Board Member/nominee.

No Independent Board Member or his or her immediate family member owns beneficially or of record any security of Nuveen Fund Advisors, Nuveen Asset Management, LLC, the Funds’ sub-adviser (previously defined as “Nuveen Asset Management” or the “Sub-Adviser”), Nuveen or any person (other than a registered investment company) directly or indirectly controlling, controlled by or under common control with Nuveen Fund Advisors, Nuveen Asset Management or Nuveen.

As of [●], 2023, each Board Member’s individual beneficial shareholdings of each Fund constituted less than 1% of the outstanding shares of the Fund. As of [●], 2023, the Board Members and executive officers as a group beneficially owned less than 1% of the outstanding shares of each Fund. Information regarding beneficial owners that, to the knowledge of the Funds, own 5% or more of any class of shares of either Fund is provided under “General Information—Shareholders of the Target Fund and the Acquiring Fund.”

Compensation

Prior to January 1, 2023, independent trustees received a $205,000 annual retainer, plus they received (a) a fee of $7,000 per day for attendance in person or by telephone at regularly scheduled meetings of the Board; (b) a fee of $3,000 per meeting for attendance in person or by telephone at special, non-regularly scheduled Board meetings where in-person attendance was required and $3,000 per meeting for attendance by telephone or in person at such meetings where in-person attendance was not required; (c) a fee of $2,500 per meeting for attendance in person or by telephone at Audit Committee meetings where in-person attendance was required and $2,250 per meeting for attendance by telephone or in person at such meetings where in-person attendance was not required; (d) a fee of $5,000 per meeting for attendance in person or by telephone at Compliance, Risk Management and Regulatory Oversight Committee meetings where in-person attendance was required and $2,000 per meeting for attendance by telephone or in person at such meetings where in-person attendance was not required; (e) a fee of $1,250 per meeting for attendance in person or by telephone at Dividend Committee meetings; (f) a fee of $500 per meeting for attendance in person or by telephone at all other committee meetings ($1,000 for shareholder meetings) where in-person attendance was required and $250 per meeting for attendance by telephone or in person at such committee meetings (excluding shareholder meetings) where in-person attendance was not required, and $100 per meeting when the Executive Committee acted as pricing committee

73

for IPOs, plus, in each case, expenses incurred in attending such meetings, provided that no fees were received for meetings held on days on which regularly scheduled Board meetings were held; and (g) a fee of $2,500 per meeting for attendance in person or by telephone at Closed-End Funds Committee meetings where in-person attendance was required and $2,000 per meeting for attendance by telephone or in person at such meetings where in-person attendance was not required; provided that no fees were received for meetings held on days on which regularly scheduled Board meetings were held. In addition to the payments described above, the Chair of the Board received $125,000, and the chairpersons of the Audit Committee, the Dividend Committee, the Compliance, Risk Management and Regulatory Oversight Committee, the Nominating and Governance Committee and the Closed-End Funds Committee received $20,000 each as additional retainers. Independent trustees also received a fee of $3,500 per day for site visits to entities that provide services to the Nuveen Funds on days on which no Board meeting was held. When ad hoc committees are organized, the Nominating and Governance Committee at the time of formation determined compensation to be paid to the members of such committee; however, in general, such fees were $1,000 per meeting for attendance in person or by telephone at ad hoc committee meetings where in-person attendance was required and $500 per meeting for attendance by telephone or in person at such meetings where in-person attendance was not required. Any compensation paid to the independent directors as members of ad hoc committees is temporary in nature and not expected to be long-term, ongoing compensation. The annual retainer, fees and expenses were allocated among the Nuveen Funds on the basis of relative net assets, although management may have, in its discretion, established a minimum amount to be allocated to each fund. In certain instances fees and expenses were allocated only to those Nuveen Funds that were discussed at a given meeting. In certain circumstances, such as during the COVID-19 pandemic, the Board may have held in-person meetings by telephonic or videographic means and were compensated at the in-person rate.

Effective January 1, 2023, independent trustees receive a $210,000 annual retainer, plus they receive (a) a fee of $7,250 per day for attendance at regularly scheduled meetings of the Board; (b) a fee of $4,000 per meeting for attendance at special, non-regularly scheduled Board meetings; (c) a fee of $2,500 per meeting for attendance at Audit Committee meetings, Closed-End Fund Committee meetings and Investment Committee Meetings; (d) a fee of $5,000 per meeting for attendance at Compliance, Risk Management and Regulatory Oversight Committee meetings; (e) a fee of $1,250 per meeting for attendance at Dividend Committee meetings; and (f) a fee of $500 per meeting for attendance at all other committee meetings, and $100 per meeting when the Executive Committee acts as pricing committee for IPOs, plus, in each case, expenses incurred in attending such meetings, provided that no fees are received for meetings held on days on which regularly scheduled Board meetings are held. In addition to the payments described above, the Chair of the Board receives $140,000, and the chairpersons of the Audit Committee, the Dividend Committee, the Compliance, Risk Management and Regulatory Oversight Committee, the Nominating and Governance Committee, the Closed-End Funds Committee and the Investment Committee receive $20,000 each as additional retainers. Independent trustees also receive a fee of $5,000 per day for site visits to entities that provide services to the Nuveen Funds on days on which no Board meeting is held. Per meeting fees for unscheduled Committee meetings or meetings of Ad Hoc or Special Assignment Committees will be determined by the Chair of such Committee based on the complexity or time commitment associated with the particular meeting. 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. In certain instances, fees and expenses will be allocated only to those Nuveen Funds that are discussed at a given meeting.

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 such Independent Board Member. The value of an Independent 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 an Independent Board

74

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 Members of each Fund who are not Independent Board Members serve without any compensation from the Funds. The Funds’ Chief Compliance Officer’s (“CCO”) compensation, which is composed of base salary and incentive compensation, is paid by the Adviser, with review and input by the Board. The Funds reimburse the Adviser for an allocable portion of the Adviser’s cost of the CCO’s incentive compensation.

The table below shows, for each Independent Board Member, the aggregate compensation paid by each Fund to the Independent Board Member/nominee for its last fiscal year.

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 Fund by the Adviser. The Board has adopted a unitary board structure. A unitary board consists of one group of board members who serves on the board of every fund in the complex. In adopting a unitary board structure, the Board Members seek to provide effective governance through establishing a board the overall composition of which will, as a body, possess the appropriate skills, diversity (including, among other things, gender, race and ethnicity), 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 (including, among other things, gender, race and ethnicity), skills,

75

experience and views among Board 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 and 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.

In an effort to enhance the independence of the Board, the Board also has a Chair who is an Independent Board Member. The Board recognizes that a chair 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 chair 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 Mr. Toth as the independent Chair of the Board. Pursuant to the Fund’s By-Laws, the Chair shall perform all duties incident to the office of Chair of the Board and such other duties as from time to time may be assigned to him or her by the Board Members or the By-Laws.

Although the Board has direct responsibility over various matters (such as advisory contracts and underwriting contracts), 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, compliance and investment risk to certain committees (as summarized below). 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 of a Fund’s operations. The Board has established seven standing committees: the Executive Committee, the Dividend Committee, the Audit Committee, the Compliance, Risk Management and Regulatory Oversight Committee, the Investment Committee, the Nominating and Governance Committee and the Closed-End Funds 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. For more information on the Board, please visit www.nuveen.com/fundgovernance.

Executive Committee. 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 Mr. Toth, Chair, Mr. Nelson and Mr. Young. The number of Executive Committee meetings of each Fund held during its last fiscal year is shown in Appendix C.

Dividend Committee. 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 Dividend Committee operates under a written charter adopted and approved by the Board. The members of the Dividend Committee are Mr. Young, Chair, Ms. Lancellotta, Mr. Nelson and Mr. Thornton. The number of Dividend Committee meetings of each Fund held during its last fiscal year is shown in Appendix C.

Audit Committee. The Board has an Audit Committee, in accordance with Section 3(a)(58)(A) of 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 NYSE. The Audit Committee assists the Board in: the

76

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. 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 Audit 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 of 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 and reviews 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 (the “Charter”) adopted and approved by the Board, which Charter conforms to the listing standards of the NYSE. 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 Mr. Nelson, Chair, Mr. Evans, Mr. Moschner, Ms. Wolff and Mr. Young, each of whom is an Independent Board Member of the Funds. A copy of the Charter is available at https://www.nuveen.com/fund-governance. The number of Audit Committee meetings of each Fund held during its last fiscal year is shown in Appendix C.

Compliance, Risk Management and Regulatory Oversight Committee. 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 under or 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 general risks related to investments which are not reviewed by other committees, such as liquidity and derivatives usage; risks related to product structure elements, such as leverage; techniques that may be used to address the foregoing risks, such as hedging and swaps and Fund operational risk and risks related to the overall operation of the Nuveen enterprise and, in each case, the controls designed to address or mitigate such risks. 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. 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. Matters not addressed at the committee level are addressed directly

77

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 Ms. Wolff, Chair, Dr. Hunter, Ms. Lancellotta, Ms. Medero, Mr. Thornton and Mr. Toth. The number of Compliance Committee meetings of each Fund held during its last fiscal year is shown in Appendix C.

Nominating and Governance Committee. 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 Board and committee structures have been developed over the years and the Nominating and Governance Committee believes these structures have provided efficient and effective governance, the Nominating and Governance 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 Nominating and Governance 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 William Siffermann, Manager of Fund Board Relations, Nuveen, 333 West Wacker Drive, Chicago, Illinois 60606. The Nominating and Governance Committee sets appropriate standards and requirements for nominations for new Board Members and each nominee is evaluated using 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 meetings with 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 Members at the time of consideration of the nominees. All candidates, however, must meet high expectations of personal integrity, independence, governance 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 https://www.nuveen.com/fund-governance, and is composed entirely of Independent Board Members, who are also “independent” as defined by NYSE listing standards. The members of the Nominating and Governance Committee are Mr. Toth, Chair, Mr. Evans, Dr. Hunter, Ms. Lancellotta, Ms. Medero, Mr. Moschner, Mr. Nelson, Mr. Thornton, Ms. Wolff and Mr. Young. The number of Nominating and Governance Committee meetings of each Fund held during its last fiscal year is shown in Appendix C.

Investment Committee. The Investment Committee is responsible for the oversight of Fund performance, investment risk management and other portfolio-related matters affecting the Funds which are not otherwise the

78

jurisdiction of the other Board committees. As part of such oversight, the Investment Committee reviews each Fund’s investment performance and investment risks, which may include, but is not limited to, an evaluation of Fund performance relative to investment objectives, benchmarks and peer group; a review of risks related to portfolio investments, such as exposures to particular issuers, market sectors, or types of securities, as well as consideration of other factors that could impact or are related to Fund performance; and an assessment of Fund objectives, policies and practices as such may relate to Fund performance. In assessing issues brought to the committee’s attention or in reviewing an investment policy, technique or strategy, the Investment Committee evaluates the risks to the Funds in adopting or recommending a particular approach or resolution compared to the anticipated benefits to the Funds and their shareholders.

In fulfilling its obligations, the Investment Committee receives quarterly reports from the investment oversight and the investment risk groups at Nuveen. Such groups also report to the full Board on a quarterly basis and the full Board participates in further discussions with fund management at its quarterly meetings regarding matters relating to Fund performance and investment risks, including with respect to the various drivers of performance and Fund use of leverage and hedging. Accordingly, the Board directly and/or in conjunction with the Investment Committee oversees the investment performance and investment risk management of the Funds. The Investment Committee operates under a written charter adopted and approved by the Board. This committee is composed of the independent Trustees of the Funds. Accordingly, the members of the Investment Committee are Dr. Hunter, Chair, Mr. Evans, Ms. Lancellotta, Ms. Medero, Mr. Moschner, Mr. Nelson, Mr. Thornton, Mr. Toth, Ms. Wolff and Mr. Young. The number of Investment Committee meetings of each Fund held during its last fiscal year is shown in Appendix C.

Closed-End Funds Committee. The Closed-End Funds Committee was established by the Board in 2012 and is responsible for assisting the Board in the oversight and monitoring of the Nuveen funds that are registered as closed-end management investment companies (“Closed-End Funds”). The Closed-End Funds 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 Closed-End Funds Committee receives updates on the secondary closed-end fund market and evaluates the premiums and discounts of the Nuveen closed-end funds, including the Funds, at each quarterly meeting. The Closed-End Funds Committee reviews, among other things, the premium and discount trends in the broader closed-end fund market, by asset category and by closed-end fund; the historical total return performance data for the Nuveen closed-end funds, including the Funds, based on net asset value and price over various periods; the volatility trends in the market; the use of leverage by the Nuveen closed-end funds, including the Funds; the distribution data of the Nuveen closed-end funds, including the Funds, and as compared to peer averages; and a summary of common share issuances, if any, and share repurchases, if any, during the applicable quarter by the Nuveen closed-end funds, including the Funds. The Closed-End Funds Committee regularly engages in more in-depth discussions of premiums and discounts of the Nuveen closed-end funds. Additionally, the Closed-End Funds Committee members participate in in-depth workshops to explore, among other things, actions to address discounts of the Nuveen closed-end funds, potential share repurchases and available leverage strategies and their use. The Closed-End Funds Committee operates under a written charter adopted and approved by the Board. The members of the Closed-End Funds Committee are Mr. Evans, Chair, Dr. Hunter, Ms. Lancellotta, Mr. Nelson, Mr. Toth and Ms. Wolff. The number of Closed-End Funds Committee meetings of each Fund held during its last fiscal year is shown in Appendix C.

The policy of the Board relating to attendance by Board Members at annual meetings of shareholders of the Funds and the number of Board Members who attended the last annual meeting of shareholders of each Fund is posted on the Funds’ website at https://www.nuveen.com/fund-governance.

Board Diversification and Board Member Qualifications. In determining that a particular Board Member was qualified to serve on the Board, the Board 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 board member 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 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.

Audit Committee Report

The Audit Committee of each Board is responsible for the oversight and monitoring of (1) the accounting and reporting policies, processes and practices, and the audit of the financial statements, of each Fund, (2) the quality and integrity of each Fund’s financial statements and (3) the independent registered public accounting

87

firm’s qualifications, performance and independence. In its oversight capacity, the Audit Committee reviews each Fund’s annual financial statements with both management and the independent registered public accounting firm and the Audit Committee meets periodically with the independent registered public accounting firm and internal auditors to consider their evaluation of each Fund’s financial and internal controls. The Audit Committee also selects, retains, evaluates and may replace each Fund’s independent registered public accounting firm. The Audit Committee is currently composed of five Independent Board Members and operates under a written charter adopted and approved by each Board. Each Audit Committee member meets the independence and experience requirements, as applicable, of the NYSE, Section 10A of the 1934 Act and the rules and regulations of the SEC.

The Audit Committee, in discharging its duties, has met with and held discussions with management and each Fund’s independent registered public accounting firm. The Audit Committee has also reviewed and discussed the audited financial statements with management. Management has represented to the independent registered public accounting firm that each Fund’s financial statements were prepared in accordance with generally accepted accounting principles. The Audit Committee has also discussed with the independent registered public accounting firm the matters required to be discussed by Statement on Auditing Standards (“SAS”) No. 114 (The Auditor’s Communication With Those Charged With Governance), which supersedes SAS No. 61 (Communication with Audit Committees). Each Fund’s independent registered public accounting firm provided to the Audit Committee the written disclosure required by Public Company Accounting Oversight Board Rule 3526 (Communications with Audit Committees Concerning Independence), and the Audit Committee discussed with representatives of the independent registered public accounting firm their firm’s independence. As provided in the Audit Committee Charter, it is not the Audit Committee’s responsibility to determine, and the considerations and discussions referenced above do not ensure, that each Fund’s financial statements are complete and accurate and presented in accordance with generally accepted accounting principles.

Based on the Audit Committee’s review and discussions with management and the independent registered public accounting firm, the representations of management and the report of the independent registered public accounting firm to the Audit Committee, the Audit Committee has recommended that the audited financial statements be included in each Fund’s Annual Report.

The current members of the Audit Committee are:

Jack B. Evans

Albin F. Moschner

John K. Nelson, Chair

Margaret L. Wolff

Robert L. Young

Audit Committee Pre-Approval Policies and Procedures.

Generally, the Audit Committee must approve each Fund’s independent registered public accounting firm’s engagements (i) with the Fund for audit or non-audit services and (ii) with the Adviser and Adviser Entities for non-audit services if the engagement relates directly to the operations and financial reporting of the

89

Fund. Regarding tax and research projects conducted by the independent registered public accounting firm for each Fund and the Adviser and Adviser Entities (with respect to the operations and financial reporting of each Fund), such engagements will be (i) pre-approved by the Audit Committee if they are expected to be for amounts greater than $10,000; (ii) reported to the Audit Committee Chair for his or her verbal approval prior to engagement if they are expected to be for amounts under $10,000 but greater than $5,000; and (iii) reported to the Audit Committee at the next Audit Committee meeting if they are expected to be for an amount under $5,000.

The Audit Committee has approved in advance all audit services and non-audit services that the independent registered public accounting firm provided to each Fund and to the Adviser and Adviser Entities (with respect to the operations and financial reporting of each Fund). None of the services rendered by the independent registered public accounting firm to each Fund or the Adviser or Adviser Entities were pre-approved by the Audit Committee pursuant to the pre-approval exception under Rule 2-01(c)(7)(i)(C) or Rule 2-01(c)(7)(ii) of Regulation S-X.

Appointment of the Independent Registered Public Accounting Firm

The Board of each Fund has appointed KPMG LLP (“KPMG”) as independent registered public accounting firm to audit the books and records of the Fund for its current fiscal year. A representative of KPMG will be present at the Target Fund’s Annual Meeting to make a statement, if such representative so desires, and to respond to shareholders’ questions. KPMG has informed each Fund that it has no direct or indirect material financial interest in the Funds, Nuveen, the Adviser or any other investment company sponsored by Nuveen.

ADDITIONAL INFORMATION ABOUT THE ACQUIRING FUND

Annual Expenses Excluding the Costs of Leverage

Based on information provided by the Adviser, the Boards considered that it was expected that the annual operating expense ratio of the combined fund following the Merger, excluding leverage, would be lower than the annual operating expense ratio of the Target Fund. The annual operating expense ratio of the Target Fund, Acquiring Fund and the combined fund following the Merger for the six-month period ended April 30, 2023 (annualized) based on the assumptions set forth in “Comparative Fee Table” at page [●] are as follows:

|  | Target Fund |  |  | Acquiring Fund |  |  | Nuveen AMT-Free Quality Municipal Income Fund Pro Forma |
Operating Expenses (as a percentage of net assets attributable to common shares) |  |  |  |  |  |  |  |  |  |  |  |
Management Fees |  |  | 1.03 | % |  |  | 0.91 | % |  |  | 0.91 | %
Other Expenses |  |  | 0.13 | % |  |  | 0.05 | % |  |  | 0.05 | %
Total Operating Expenses |  |  | 1.16 | % |  |  | 0.96 | % |  |  | 0.96 | %

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

General

The by-laws of the Acquiring Fund provide that by becoming a shareholder of the Fund, each shareholder shall be deemed to have agreed to be bound by the terms of the Declaration of Trust and by-laws. However, neither the Declaration of Trust nor the by-laws purport to require the waiver of a shareholder’s rights under the federal securities laws.

Shareholder and Trustee Liability

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 Acquiring Fund and requires that notice of such limited liability be given in each obligation, contract or instrument made or issued by the Acquiring Fund or the trustees. The Acquiring Fund’s declaration of trust further provides for indemnification out of the assets and property of the Acquiring Fund for all loss and expense of any shareholder held personally liable for the obligations of the Acquiring 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 provides that the obligations of the Acquiring Fund are not binding upon the Acquiring Fund’s trustees individually, but only upon the assets and property of the Acquiring Fund, and that the trustees will not be liable for errors of judgment or mistakes of fact or law. However, nothing in the Acquiring Fund’s declaration of trust 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.

Anti-Takeover Provisions

The Acquiring Fund’s declaration of trust and by-laws include provisions that could limit the ability of other entities or persons to acquire control of the Acquiring Fund or to convert the Acquiring Fund to open-end

91

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 entitled to vote, voting as a single class, except as described below, to authorize (1) a conversion of the Acquiring Fund from a closed-end to an open-end investment company, (2) a merger or consolidation of the Acquiring Fund with any corporation, association, trust or other organization or a reorganization or recapitalization of the Acquiring Fund or a series or class of the Acquiring Fund, (3) a sale, lease or transfer of all or substantially all of the Acquiring Fund’s assets (other than in the regular course of the Acquiring Fund’s investment activities), (4) in certain circumstances, a termination of the Acquiring 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 Acquiring Fund’s outstanding common shares and preferred shares entitled to vote, 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. For the purposes of the foregoing, the term “recapitalization” will not mean, without limitation, the issuance or redemption of preferred shares pursuant to the terms of the declaration of trust or the applicable Statement adopted with respect to such preferred shares, whether or not in conjunction with the issuance, retirement or redemption of other securities or indebtedness of the Acquiring Fund. However, approval of shareholders is not required 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) of 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 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 entitled to vote, 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 interests of the Acquiring Fund.

In addition, the Acquiring Fund’s by-laws require the Board be divided into three classes with staggered terms. 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 Acquiring Fund’s trustees.

The by-laws of the Acquiring Fund include a Control Share Provision pursuant to which a shareholder who obtains beneficial ownership of Acquiring Fund common shares in a Control Share Acquisition may exercise voting rights with respect to such shares only to the extent authorized by the affirmative vote of the holders of a majority (more than 50%) of the shares of the Acquiring Fund that are not held by Acquiring Fund officers or any person who has acquired common shares in a Control Share Acquisition. See “Proposal No. 1—C. Information About the Merger—Summary Description of Massachusetts Business Trusts—The Funds—Shareholder Voting.” See also “General Information—Additional Information About the Solicitation” at page [●] for a description of certain legal matters with respect to the Control Share Provision.

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 Acquiring Fund in a tender offer or similar transaction. The overall effect of these provisions is to render

92

more difficult the accomplishment of a merger or the assumption of control by a third party. However, they provide 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 Acquiring 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 Acquiring Fund.

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

Procedural Requirements on Derivative Actions, Exclusive Jurisdiction and Jury Trial Waiver

The by-laws of the Acquiring Fund contain certain provisions affecting potential shareholder claims against the Fund, including procedural requirements for derivative actions, an exclusive forum provision, and the waiver of shareholder rights to a jury trial. Massachusetts is considered a “universal demand” state, meaning that under Massachusetts corporate law a shareholder must make a demand on the company before bringing a derivative action (i.e., a lawsuit brought by a shareholder on behalf of the company). The by-laws of the Acquiring Fund provide detailed procedures for the bringing of derivative actions by shareholders (the “Demand By-Law”) which are modeled on the substantive provisions of the Massachusetts corporate law derivative demand statute, which has been applied by courts to Massachusetts business trusts, like the Acquiring Fund. The Demand By-Law is intended to permit legitimate inquiries and claims while avoiding the time, expense, distraction, and other harm that can be caused to the Acquiring Fund or its shareholders as a result of spurious shareholder demands and derivative actions. Among other things, the Demand By-Law:

| • |  | provides that before bringing a derivative action, a shareholder must make a written demand to the Acquiring Fund;

| • |  | establishes a 90 day review period, subject to extension in certain circumstances, for the Board of Trustees to evaluate the shareholder’s demand;

| • |  | establishes a mechanism for the Board of Trustees to submit the question of whether to maintain a derivative action to a vote of shareholders;

| • |  | provides that if the Acquiring Fund does not notify the requesting shareholder of the rejection of the demand within the applicable review period, the shareholder may commence a derivative action;

| • |  | establishes bases upon which a trustee will not be considered to be not independent for purposes of evaluating a derivative demand; and

| • |  | provides that if the trustees who are independent for purposes of considering a shareholder demand determine in good faith within the applicable review period that the maintenance of a derivative action is not in the best interest of the Acquiring Fund, the shareholder shall not be permitted to maintain a derivative action unless he or she first sustains the burden of proof to the court that the decision of the trustees not to pursue the requested action was not a good faith exercise of their business judgment on behalf of the Fund.

The Demand By-Law may be more restrictive than procedures for bringing derivative suits applicable to other investment companies.

93

The by-laws also require that actions by shareholders against the Acquiring Fund, except for actions under the U.S. federal securities laws, be brought only in a certain federal court in Massachusetts, or if not permitted to be brought in federal court, then in the Business Litigation Session of the Massachusetts Superior Court in Suffolk County (the “Exclusive Jurisdictions”), and that the right to jury trial be waived to the fullest extent permitted by law. Other investment companies may not be subject to similar restrictions. The designation of Exclusive Jurisdictions may make it more expensive for a shareholder to bring a suit than if the shareholder were permitted to select another jurisdiction. Also, the designation of Exclusive Jurisdictions and the waiver of jury trials limit a shareholder’s ability to litigate a claim in the jurisdiction and in a manner that may be more favorable to the shareholder. It is possible that a court may choose not to enforce these provisions of the Acquiring Fund’s by-laws.

Reference should be made to the Acquiring Fund’s declaration of trust and by-laws 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, 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.

If the Acquiring Fund converted to an open-end investment company, it would be required to redeem all its preferred 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 Merger 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 MFP Shares

The Acquiring Fund’s outstanding MFP Shares, which are expected to remain outstanding following the completion of the Merger, are as follows:

Series |  | Shares Outstanding |  |  | Par Value Per Share |  |  | Liquidation Preference Per Share |  |  | Original Issue Date |  | Term Redemption Date
Series A MFP Shares |  |  | 1,350 |  |  | $ | 0.01 |  |  | $ | 100,000 |  |  | February 2018 |  | February 3, 2048
Series B MFP Shares |  |  | 3,350 |  |  | $ | 0.01 |  |  | $ | 100,000 |  |  | March 2018 |  | March 2, 2028
Series C MFP Shares |  |  | 2,380 |  |  | $ | 0.01 |  |  | $ | 100,000 |  |  | March 2018 |  | March 2, 2028
Series D MFP Shares |  |  | 330,900 |  |  | $ | 0.01 |  |  | $ | 1,000 |  |  | March 2019 |  | March 1, 2029

The Series A MFP Shares, Series B MFP Shares and Series C MFP Shares were issued to qualified institutional buyers through private transactions exempt from registration under the 1933 Act. The Series D MFP Shares were issued in public offerings registered under the 1933 Act. The Series A MFP Shares and the Series B MFP Shares are in the “Variable Rate Mode” (the “VR Mode”) and are “Adjustable Rate.” The dividend on each of the Series A MFP Shares and the Series B MFP Shares is currently a variable rate determined by reference to an index rate, plus an applicable spread. So long as the MFP Shares of a series are in the current VR Mode, the Acquiring Fund and the beneficial owner or owners of the MFP Shares of the applicable series may agree from time to time to adjust the dividend rate and other economic terms.

The Series C MFP Shares are in the Variable Rate Demand Mode (the “VRD Mode”), in which the adjustable dividend rate is set weekly by a remarketing agent. Holders of the outstanding Series C MFP Shares have the right to give notice on any business day to tender the securities for remarketing in seven days. The outstanding Series C MFP Shares are also subject to a mandatory tender for remarketing upon the occurrence of certain events, such as the non-payment of dividends by the Acquiring Fund. Should a remarketing be unsuccessful, the dividend rate will reset to a maximum rate as defined in the governing documents of the Series C MFP Shares.

The Series C MFP Shares 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 for the Series C MFP Shares requires the liquidity provider to purchase from holders all outstanding Series C MFP Shares tendered for sale that were not successfully remarketed. The liquidity provider also must purchase all outstanding Series C MFP Shares prior to termination of the purchase agreement, including by reason of the failure of the liquidity provider to maintain the requisite level of short-term ratings, if the Acquiring Fund has not obtained an alternate purchase agreement before the termination date.

The obligation of the liquidity provider for the Series C MFP Shares to purchase the outstanding Series C MFP Shares pursuant to the purchase agreement for such series runs to the benefit of the holders of the outstanding Series C MFP Shares and is unconditional and irrevocable, and as such the short-term rating assigned to the outstanding Series C MFP Shares is directly linked to the short-term creditworthiness of the associated liquidity provider. The liquidity provider for the Series C MFP Shares entered into a purchase agreement with respect to the outstanding Series C MFP Shares, subject to periodic extension by agreement with the Acquiring Fund.

The Series D MFP Shares are in the Variable Rate Remarketed Mode (the “VRR Mode”), in which the dividend generally is a clearing rate determined each business day by a remarketing agent appointed by the Acquiring Fund. Beneficial owners of MFP Shares of each series in the VRR Mode generally may on any business day tender their MFP Shares to the remarketing agent, which has agreed to use its best efforts to remarket in seven days any tendered MFP Shares. In the event of a failed remarketing, the dividend rate will step

95

up, and the Acquiring Fund will redeem all outstanding MFP Shares of the applicable series 365 days after the failed remarketing tender date, subject to a prior successful remarketing by the remarketing agent of all outstanding MFP Shares of the applicable series or the successful transition by the Acquiring Fund of MFP Shares of the applicable series to a new mode.

The Acquiring Fund established the term of both the VR Mode for the Series A MFP Shares and Series B MFP Shares, the VRD Mode for the Series C MFP Shares and the VRR Mode for the Series D MFP Shares as ending on their respective Term Redemption Dates, subject to earlier redemption, repurchase or transition to a new mode by the Acquiring Fund. Under the statements establishing and fixing the rights and preferences of the Outstanding MFP Shares, as supplemented (the “Statements”), the Acquiring Fund may terminate the VR Mode, VRD Mode or VRR Mode early and transition the applicable MFP Shares to a new mode (and, thereafter, until the term redemption date, subsequent new modes), during which many of the economic terms of the MFP Shares set forth in such Statements may be modified. Modified terms for a new mode may include provisions with respect to (but not limited to) optional tender provisions, mandatory tender provisions, a liquidity facility or other credit enhancement, mandatory purchase provisions, the dividend rate setting provisions (including as to any maximum rate), and, if the dividend may be determined by reference to an index, formula or other method, the manner in which it will be determined and redemption provisions.

Dividends

The holders of outstanding MFP Shares of each series are entitled to receive, when, as and if declared by the Board, out of funds legally available therefor in accordance with the Acquiring Fund’s declaration of trust and applicable law, cumulative cash dividends at the dividend rate or rates for the outstanding MFP Shares of such series payable on the dividend payment dates with respect to the outstanding MFP Shares of such series. Holders of outstanding MFP Shares are not entitled to any dividend, whether payable in cash, property or shares, in excess of such cumulative dividends on the outstanding MFP Shares. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or payments on outstanding MFP Shares which may be in arrears, and no additional sum of money will be payable in respect of such arrearage. In no circumstances may the dividend rate exceed 15% per annum with respect to any dividend rate period.

Redemption

The outstanding MFP Shares of each series are subject to optional and mandatory redemption in certain circumstances. The Acquiring Fund is obligated to redeem the outstanding MFP Shares on the Term Redemption Date set forth for each series in the table above, unless earlier redeemed or repurchased by the Acquiring Fund, at a redemption price per share equal to the applicable liquidation preference per share ($100,000 in the case of Series A MFP Shares, Series B MFP Shares and Series C MFP Shares, or $1,000 in the case of Series D MFP Shares) plus any accumulated but unpaid dividends (whether or not earned or declared). In the event the Acquiring Fund fails to comply with asset coverage and/or effective leverage ratio requirements, as applicable, 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. The Acquiring Fund is obligated to redeem all of the outstanding MFP Shares of the applicable series, in the event a mode change is initiated and a failed transition to a new mode occurs, if such failure is not cured within the applicable cure period. In addition, as described above, the Acquiring Fund will be obligated to redeem all outstanding Series D MFP Shares 365 days after a failed remarketing tender date, subject to a prior successful remarketing by the remarketing agent of all outstanding Series D MFP Shares. Outstanding MFP Shares also may be redeemed in whole at any time or in part from time to time at the option of the Acquiring Fund at a redemption price per share equal to the liquidation preference per share plus any accumulated but unpaid dividends (whether or not earned or declared).

96

Voting and Consent Rights

Except as otherwise provided in the Acquiring Fund’s declaration of trust, the MFP Statements, or as otherwise required by applicable law, (i) each holder of outstanding MFP Shares is entitled to one vote for each outstanding MFP Share held on each matter submitted to a vote of shareholders of the Acquiring Fund, and (ii) the holders of outstanding MFP 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 outstanding MFP 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 outstanding MFP Shares, voting as a single class, elect the balance of the trustees of the Acquiring Fund.

Holders of outstanding MFP Shares of each series, 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 outstanding MFP Shares or holders of outstanding MFP Shares of the applicable series. In addition, holders of outstanding Series A MFP Shares and Series B MFP Shares have certain consent rights under the purchase agreement for the outstanding MFP Shares of the applicable series with respect to certain actions that would affect their investment in the Acquiring Fund. Holders of outstanding MFP 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 outstanding MFP Shares, are entitled to elect additional trustees in the event 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 outstanding MFP Shares are senior in priority to the Acquiring Fund’s common shares as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund. The outstanding MFP Shares of each series have equal priority as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund with each other and the other preferred shares of the Acquiring Fund, including the outstanding VRDP Shares, the outstanding AMTP Shares and the New VRDP Shares to be issued in connection with the Merger, if any.

Description of Outstanding Acquiring Fund AMTP Shares

The outstanding AMTP Shares of the Acquiring Fund, each offered to qualified institutional buyers in private transactions exempt from registration under the 1933 Act, which are expected to remain outstanding following the completion of the Merger, are as follows:

Series |  | Shares Outstanding |  |  | Par Value Per Share |  |  | Liquidation Preference Per Share |  |  | Original Issue Date |  | Mandatory Redemption Date
Series 2028-1 AMTP Shares |  |  | 1,730 |  |  | $ | 0.01 |  |  | $ | 100,000 |  |  | December 13, 2018 |  | December 1, 2028

Holders of outstanding AMTP Shares are entitled to receive cash dividends when, as and if declared by the Acquiring Fund’s Board. The amount of dividends per outstanding AMTP 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 outstanding AMTP Shares. In no circumstances may the dividend rate exceed 15% per annum with respect to any dividend rate period.

97

The outstanding AMTP Shares are subject to optional and mandatory redemption in certain circumstances. The Acquiring Fund is obligated to redeem the outstanding AMTP Shares on the dates listed above, unless earlier redeemed or repurchased by the Acquiring Fund, at a redemption price per share equal to the liquidation preference per share ($100,000) plus any accumulated but unpaid dividends thereon. The outstanding AMTP 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 preference per share plus any accumulated but unpaid dividends thereon, plus a certain redemption premium. 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 or the Statement for the outstanding AMTP Shares or as otherwise required by applicable law, (1) each holder of outstanding AMTP Shares is entitled to one vote for each outstanding AMTP Share held on each matter submitted to a vote of shareholders of the Acquiring Fund, and (2) the holders of outstanding AMTP 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 outstanding AMTP 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 outstanding AMTP Shares, voting as a single class, elect the balance of the trustees of the Acquiring Fund.

With respect to certain actions that would materially and adversely affect any preference, right or power of the outstanding AMTP Shares or holders of outstanding AMTP Shares, holders of outstanding AMTP Shares vote separately. In addition, holders of outstanding AMTP Shares have certain consent rights under the purchase agreement for the AMTP Shares with respect to certain actions that would affect their investment in the Acquiring Fund. Holders of outstanding AMTP 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. Holders of preferred shares, including outstanding AMTP Shares, are entitled to elect additional trustees constituting, when added to the two trustees elected exclusively by the holders of preferred shares, a majority of the 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 outstanding AMTP 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 outstanding AMTP 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 the outstanding VRDP Shares, the outstanding MFP Shares and the New VRDP Shares to be issued in connection with the Merger, if any.

Under the statements establishing and fixing the rights and preferences of the outstanding VRDP Shares (the “VRDP Statements”), the outstanding VRDP Shares of each series pay an adjustable dividend rate set weekly by a remarketing agent. Holders of the outstanding VRDP Shares of each series have the right to give notice on any business day to tender the securities for remarketing in seven days. The outstanding VRDP Shares of each series are also subject to a mandatory tender for remarketing upon the occurrence of certain events, such as the non-payment of dividends by the Acquiring Fund.

The obligation of the liquidity provider for the outstanding VRDP Shares of each series to purchase the outstanding VRDP Shares of such series pursuant to the purchase agreement for such series runs to the benefit of the holders of the outstanding VRDP Shares of such series and is unconditional and irrevocable, and as such the short-term ratings assigned to the outstanding VRDP Shares of each series are directly linked to the short-term creditworthiness of the associated liquidity provider. The liquidity provider for the outstanding VRDP Shares of each series entered into a purchase agreement with respect to the outstanding VRDP Shares of such series, subject to periodic extension by agreement with the Acquiring Fund.

Dividends

The holders of outstanding VRDP Shares of each series are entitled to receive, when, as and if declared by the Board, out of funds legally available therefor in accordance with the Acquiring Fund’s declaration of trust and applicable law, cumulative cash dividends at the dividend rate for the outstanding VRDP Shares of such series payable on the dividend payment dates with respect to the outstanding VRDP Shares of such series. Holders of outstanding VRDP Shares are not entitled to any dividend, whether payable in cash, property or shares, in excess of such cumulative dividends on the outstanding VRDP Shares. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or payments on outstanding VRDP Shares which may be in arrears, and no additional sum of money will be payable in respect of such arrearage. The amount of dividends per outstanding VRDP Share payable on any dividend payment date will equal the sum of

99

dividends accumulated but not yet paid for each dividend reset period during the relevant monthly dividend period. In no circumstances may the dividend rate exceed 15% per annum with respect to any dividend rate period.

Redemption

The outstanding VRDP Shares of each series are subject to optional and mandatory redemption in certain circumstances. The Acquiring Fund is obligated to redeem the outstanding VRDP Shares on the Mandatory Redemption Date set forth for each series in the table above, unless earlier redeemed or repurchased by the Acquiring Fund, at a redemption price per share equal to the liquidation preference per share ($100,000) plus any accumulated but unpaid dividends (whether or not earned or declared). Pursuant to the VRDP Statement for the outstanding VRDP Shares of each series and the fee agreement with the liquidity provider for such series, the Acquiring Fund will have an obligation to redeem, at a redemption price equal to $100,000 per share plus accumulated but unpaid dividends thereon (whether or not earned or declared) until, but excluding, the date fixed by the Board for redemption, shares of such series 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. The Acquiring Fund also will redeem, at a redemption price equal to the liquidation preference per share plus accumulated but unpaid dividends thereon (whether or not earned or declared) until, but excluding, the date fixed by the Board for redemption, such number of preferred shares as is necessary to achieve compliance, if the Acquiring Fund fails to maintain the minimum VRDP asset coverage required under the 1940 Act and the Acquiring Fund’s agreement with the liquidity provider for the outstanding VRDP Shares of the applicable series, and such failure is not cured by the applicable cure date. Outstanding VRDP Shares also may be redeemed in whole at any time or in part from time to time at the option of the Acquiring Fund at a redemption price per share equal to the liquidation preference per share plus any accumulated but unpaid dividends (whether or not earned or declared).

Voting and Consent Rights

Except as otherwise provided in the Acquiring Fund’s declaration of trust, the VRDP Statements, or as otherwise required by applicable law, (i) each holder of outstanding VRDP Shares is entitled to one vote for each outstanding VRDP Share held on each matter submitted to a vote of shareholders of the Acquiring Fund, and (ii) the holders of outstanding VRDP 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 outstanding VRDP 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 outstanding VRDP Shares, voting as a single class, elect the balance of the trustees of the Acquiring Fund.

Holders of outstanding VRDP Shares of each series, 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 outstanding VRDP Shares or holders of outstanding VRDP Shares of the applicable series.

The Bank of New York Mellon will serve in such capacity for the New VRDP Shares issued in the Merger.

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 Merger SAI for additional information. Investors should rely on their own tax adviser for advice about the particular federal, foreign, 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 Merger occurs) 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 invests primarily in municipal securities. 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 imposes an alternative minimum tax with respect to 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. Pursuant to its non-fundamental investment policy, the Acquiring Fund does not intend to acquire securities whose income is 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, if any. For taxable years beginning after December 31, 2022, federal income tax law also imposes an alternative minimum tax on corporations. Exempt-interest dividends therefore may also affect the corporate alternative minimum tax liability of some corporate shareholders.

Future legislation could limit the exclusion from gross income of tax-exempt interest (which includes exempt-interest dividends received from the Acquiring Fund). Such legislation could affect the value of the municipal securities owned by the Acquiring Fund. The likelihood of such legislation being enacted cannot be predicted. Shareholders should consult their own tax advisers regarding the potential consequences of future legislation on their investment in the Acquiring Fund.

101

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. Distributions of net capital gains (the excess of net long-term capital gains over net short-term capital losses) 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 20%. In addition, certain individuals, estates and trusts are subject to a 3.8% Medicare tax on net investment income, including net capital gains and other taxable dividends. Corporate shareholders are taxed on capital gain at the same rates as apply to ordinary income. 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 gains. If the Acquiring Fund retains any net capital gains 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 gains, 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, (1) will be required to include in income for federal income tax purposes, as long-term capital gain, their share of such undistributed amount; (2) 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 (3) 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 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 (2) of the preceding sentence.

The Internal Revenue Service (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 reports dividends made with respect to common shares and preferred shares as consisting of particular types of income (e.g., exempt interest, net capital gains and ordinary income) in accordance with each class’s proportionate share of the total dividends paid by the Acquiring Fund with respect to the year.

Dividends declared by the Acquiring Fund in October, November or December to shareholders of record in one of those months and paid during the following January will be treated as having been paid by the Acquiring Fund and received by shareholders on December 31 of 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. Current federal income tax law taxes both long-term and short-term capital gains of corporations at the same rates applicable to ordinary income. However, for noncorporate taxpayers, long-term capital gains are currently taxed at a maximum federal income tax rate of 20%, while short-term capital gains are currently taxed at ordinary income rates. An additional 3.8% Medicare tax may also apply to certain individual, estate or trust shareholders’ capital gain from the sale or other disposition of their shares. 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

102

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 distributions of net capital gains received (and undistributed net capital gain designated by the Acquiring Fund that is deemed to be 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. The deductibility of capital losses is subject to limitations.

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 federal 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 income it is required to accrue, to qualify as a RIC and (with respect to its ordinary income and capital 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’s investment in lower rated or unrated debt securities may present issues for the Acquiring Fund if the issuers of these securities default on their obligations because the federal income tax consequences to a holder of such securities are not certain.

The Acquiring Fund may be required to withhold federal income tax at a rate of 24% from all distributions (including exempt-interest dividends) and redemption proceeds payable to a shareholder if the shareholder fails to provide the Acquiring Fund with his, her or its correct taxpayer identification number or to make required certifications, or if the shareholder has been notified by the IRS (or the IRS notifies the Acquiring Fund) that he, she or it is subject to backup withholding. 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 federal income tax liability.

The Foreign Account Tax Compliance Act (“FATCA”) generally requires the Acquiring Fund to obtain information sufficient to identify the status of each of its shareholders. If a shareholder fails to provide this information or otherwise fails to comply with FATCA, the Acquiring Fund may be required to withhold under FATCA at a rate of 30% with respect to that shareholder on Acquiring Fund dividends and distributions and

103

redemption proceeds. The Acquiring Fund may disclose the information that it receives from (or concerning) its shareholders to the IRS, non-U.S. taxing authorities or other parties as necessary to comply with FATCA, related intergovernmental agreements or other applicable law or regulation. Investors are urged to consult their own tax advisers regarding the applicability of FATCA and any other reporting requirements with respect to the investor’s own situation, including investments through an intermediary.

Pursuant to proposed regulations, the Treasury Department has indicated its intent to eliminate the requirements under FATCA of withholding on gross proceeds from the sale, exchange, maturity or other disposition of relevant financial instruments (including redemption of stock). The Treasury Department has indicated that taxpayers may rely on these proposed regulations pending their finalization.

With respect to the preferred shares of the Acquiring Fund to be issued in the Merger, if any, the Acquiring Fund will receive an opinion from special tax counsel that the preferred shares will constitute equity of the Acquiring Fund, and the foregoing discussion and the tax opinion received by the Funds regarding certain aspects of the Merger, including that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Code, relies on the position that the preferred shares will constitute equity of the Acquiring Fund. Accordingly, distributions with respect to the preferred shares (other than distributions in redemption of preferred shares subject to Section 302(b) of the Code) will generally constitute dividends to the extent of the Acquiring Fund’s current or accumulated earnings and profits, as calculated for federal income tax purposes and to the extent allocable to such distribution. Because the treatment of a corporate security as debt or equity is determined on the basis of the facts and circumstances of each case, and no controlling precedent exists for any preferred shares to be issued in the Merger, there can be no assurance that the IRS will not challenge special tax counsel’s opinion and the Acquiring Fund’s treatment of the preferred shares as equity. If the IRS were to succeed in such a challenge, holders of preferred shares could be characterized as receiving taxable interest income rather than exempt-interest or other dividends, possibly requiring them to file amended income tax returns and retroactively to recognize additional amounts of ordinary income and pay additional tax, interest and penalties.

Net Asset Value

The net asset value (“NAV”) of the Acquiring Fund’s common shares is determined by dividing the total value of the Acquiring Fund’s portfolio investments and other assets, less any liabilities, by the total number of common shares outstanding.

The Acquiring Fund’s NAV per share is determined as of the close of trading (normally 4:00 p.m., Eastern Time) on each day the NYSE is open for business. The Acquiring Fund’s latest NAV per share is available on the Acquiring Fund’s website at www.nuveen.com. The Acquiring Fund’s NAV 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 common shares outstanding. The result, rounded to the nearest cent, is the NAV per share. The Acquiring Fund reserves the right to change the time as of which its NAV is calculated if the NYSE closes earlier, or as permitted by the SEC.

In determining the Acquiring Fund’s NAV, portfolio instruments generally are valued using prices provided by independent pricing services or obtained from other sources, such as broker-dealer quotations. Exchange-traded instruments generally are valued at the last reported sales price or official closing price on an exchange, if available. Independent pricing services typically value non-equity portfolio instruments utilizing a range of market-based inputs and assumptions, including readily available market quotations obtained from broker-dealers making markets in such instruments, cash flows and transactions for comparable instruments. In valuing municipal securities, the pricing services may also consider, among other factors, the yields or prices of municipal securities of comparable quality, type of issue, coupon, maturity and rating and the obligor’s credit characteristics considered relevant by the pricing service or the Board of Trustees’ designee. In pricing certain securities, particularly less liquid and lower quality securities, the pricing services may consider information about a security, its issuer or market activity provided by Nuveen Fund Advisors or Nuveen Asset Management.

104

If a price cannot be obtained from a pricing service or other pre-approved source, or if Nuveen Fund Advisors deems such price to be unreliable, or if a significant event occurs after the close of the local market but prior to the time at which the Acquiring Fund’s net asset value is calculated, a portfolio instrument will be valued at its fair value. Nuveen Fund Advisors may determine that a price is unreliable in various circumstances. For example, a price may be deemed unreliable if it has not changed for an identified period of time, or has changed from the previous day’s price by more than a threshold amount, and recent transactions and/or broker dealer price quotations differ materially from the price in question.

The Board of Trustees has designated Nuveen Fund Advisors as the Acquiring Fund’s valuation designee pursuant to Rule 2a-5 under the 1940 Act and delegated to Nuveen Fund Advisors the day-to-day responsibility of making fair value determinations. All fair value determinations are made in accordance with procedures adopted by Nuveen Fund Advisors, subject to the oversight of the Board of Trustees. As a general principle, the fair value of a portfolio instrument is the amount that an owner might reasonably expect to receive upon the instrument’s current sale. A range of factors and analysis may be considered when determining fair value, including relevant market data, interest rates, credit considerations and/or issuer specific news. However, fair valuation involves subjective judgments and it is possible that the fair value determined for a portfolio instrument may be materially different from the value that could be realized upon the sale of that instrument.

Further, neither Fund is aware of any person who, as of [●], 2023, “controls” (within the meaning of the 1940 Act) the Fund. Under the 1940 Act, a person who beneficially owns, directly or indirectly, more than 25% of the voting securities of a fund is presumed to control the fund.

Expenses of Proxy Solicitation

Preferred shareholders will not bear any costs of the Merger. The costs of the Merger are estimated to be $1,325,000, but the actual costs may be higher or lower than that amount. These costs represent the estimated nonrecurring expenses of the Funds in carrying out their obligations under the Agreement and consist of management’s estimate of professional service fees, printing costs and mailing charges related to the proposed Merger. Based on the expected benefits of the Merger to each Fund, each of the Target Fund and the Acquiring Fund is expected to be allocated $845,000 and $480,000, respectively, of the estimated expenses in connection with the Merger (0.74% and 0.01%, respectively, of the Target Fund’s and the Acquiring Fund’s average net assets applicable to common shares for the six months ended April 30, 2023). If the Merger is not consummated for any reason, including because the requisite shareholder approvals are not obtained, each of the Funds, and common shareholders of each of the Funds indirectly, will still bear the costs of the Merger.

The Funds have engaged Computershare Fund Services to assist in the solicitation of proxies at an estimated aggregate cost of $[●] per Fund plus reasonable expenses, which is included in the foregoing estimate.

Shareholder Proposals

The Acquiring Fund expects to hold its 2024 annual meeting of shareholders in August 2024. To be considered for presentation at the 2024 annual meeting of shareholders of the Acquiring Fund, shareholder proposals submitted pursuant to Rule 14a-8 under the 1934 Act must have been received at the offices of the

107

Fund, 333 West Wacker Drive, Chicago, Illinois 60606, not later than March 8, 2024. A shareholder wishing to provide notice in the manner prescribed by Rule 14a-4(c)(1) under the 1934 Act of a proposal submitted outside of the process of Rule 14a-8 for the 2024 annual meeting must, pursuant to the Acquiring Fund’s by-laws, submit such written notice to the Acquiring Fund no earlier than April 7, 2024 and no later than April 22, 2024. Timely submission of a proposal does not mean that such proposal will be included in a proxy statement.

If Proposal No. 1 is approved at the Target Fund’s and the Acquiring Fund’s Meeting and the Merger is consummated, the Target Fund will cease to exist and will not hold its next annual meeting. If the Merger is not approved or is not consummated, the Target Fund will hold its next annual meeting of shareholders, expected to be held in November or December 2024.

To be considered for presentation at the 2024 annual meeting of shareholders of the Target Fund, shareholder proposals submitted pursuant to Rule 14a-8 under the 1934 Act must be received at the offices of the Fund, 333 West Wacker Drive, Chicago, Illinois 60606, not later than [●], 2024. A shareholder wishing to provide notice in the manner prescribed by Rule 14a-4(c)(1) under the 1934 Act of a proposal submitted outside of the process of Rule 14a-8 for the 2024 annual meeting must, pursuant to the Fund’s by-laws, submit such written notice to the Target Fund no earlier than [●], 2024 and no later than [●], 2024. Timely submission of a proposal does not mean that such proposal will be included in a proxy statement.

Proposals may be presented by shareholders only if advance notice is duly submitted in accordance with applicable law and the Fund’s governing documents, and the subject matter of such proposal is a matter upon which the proposing shareholder is entitled to vote. Each Fund’s by-laws require shareholders submitting advance notices of proposals of business or nominations for election as Board Members to provide the Fund with certain information and representations about the proponent shareholder and the nominees or business being proposed. No shareholder proposal will be considered at any meeting of shareholders of a Fund if such proposal does not satisfy all applicable requirements set forth in the by-laws and, unless required by applicable law, no matter shall be considered at or brought before any meeting of shareholders unless such matter has been deemed a proper matter for shareholder action by the chair of the meeting, the Chief Administrative Officer of the Fund or at least sixty-six and two-thirds percent (66 2/3%) of the Fund’s trustees. A shareholder wishing to present a proposal of business or nomination is encouraged to carefully review the applicable Fund’s by-laws.

Copies of the by-laws of each Fund are available on the EDGAR Database on the SEC’s website at www.sec.gov.

Shareholder Communications

Fund shareholders who want to communicate with the Board or any individual Board Member should write to the attention of William Siffermann, Manager of Fund Board Relations, Nuveen Investments, 333 West Wacker Drive, Chicago, Illinois 60606. The letter should indicate that you are a Fund shareholder and note the Fund or Funds that you own. If the communication is intended for a specific Board Member and so indicates, it will be sent only to that Board Member. If a communication does not indicate a specific Board Member it will be sent to the Independent Chair and the outside counsel to the Independent Board Members for further distribution as deemed appropriate by such persons.

Fiscal Year

The fiscal year end for the Target Fund is May 31. The fiscal year end for the Acquiring Fund is October 31.

108

Additional Information About the Solicitation

On January 14, 2021, a shareholder of certain Nuveen closed-end funds (the “Subject Funds”) filed a civil complaint in the U.S. District Court for the Southern District of New York (the “District Court”) against the Subject Funds and their trustees, seeking a declaration that the Subject Funds’ Control Share Provision violates the 1940 Act and rescission of the Subject Fund’s Control Share Provision. On February 18, 2022, the District Court granted summary judgment in favor of the plaintiff on its claims for rescission and declaratory judgment. Following careful review of the judgment of the District Court, on February 24, 2022, the Board of Trustees amended the by-laws of the Subject Funds and all other Nuveen closed-end funds whose by-laws include a Control Share Provision, including the Target Fund and the Acquiring Fund, to provide that the Control Share Provision shall be of no force and effect for so long as the judgment of the District Court is effective and that if the judgment of the District Court is reversed, overturned, vacated, stayed, or otherwise nullified, the Control Share Provision will be automatically reinstated and apply to any beneficial owner of common shares acquired in a Control Share Acquisition, regardless of whether such Control Share Acquisition occurs before or after such reinstatement, for the duration of the stay or upon issuance of the mandate reversing, overturning, vacating or otherwise nullifying the judgment of the District Court. As a result, the Funds’ Control Share Provision will not be in effect with respect to this meeting. The judgment of the District Court is currently being appealed to the U.S. Court of Appeals for the Second Circuit.

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 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.

Upon at least five business days advance written notice to a Fund, a shareholder of the Fund is entitled to inspect and copy at the offices where they are maintained, a list of shareholders and their addresses entitled to be present and to vote at that Fund’s Meeting, provided that the written notice describes with reasonable particularity the purpose of the demand, that the demand is made in good faith and for a proper purpose, and the records requested are directly connected to that purpose, and provided further that the Trustees shall not have determined in good faith that disclosure of the records sought would adversely affect the Fund in the conduct of

109

its business or constitute material non-public information at the time when the shareholder’s notice of demand to inspect and copy is received by the Fund. The Fund may furnish the shareholder with copies of the shareholder list, including copies furnished through an electronic transmission. Shareholders interested in inspecting the list of shareholders for their respective Fund(s) should contact (800) 257-8787 for additional information. To email the Fund(s), please visit www.nuveen.com/contact-us.

In the absence of a quorum for a particular matter, business may proceed on any other matter or matters that may properly come before the Meetings if there is present, in person (including virtually) or by proxy, a quorum of shareholders in respect of such other matters. The chair of the meeting may, whether or not a quorum is present, adjourn the meeting with respect to one or more matters to be considered on behalf of a Fund without further notice to permit further solicitation of proxies.

By returning the enclosed form of proxy, you are authorizing the persons named on the proxy to vote in the manner directed in the proxy, and in their discretion on any other matter that properly comes before the Meetings.

Broker-dealer firms holding shares in “street name” for the benefit of their customers and clients are generally required to request the instruction of such customers and clients on how to vote their shares on the proposals. A broker-dealer firm that is subject to the rules of the NYSE and 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 Proposal No. 1 described in this Joint Proxy Statement/Prospectus. 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 the proposal may be deemed to be an instruction to the broker-dealer to vote such shares in the broker-dealer’s discretion. However, a broker-dealer firm subject to the rules of the NYSE and that has not received instructions from a customer prior to the date specified in its request for voting instructions may vote such customer’s shares on Proposal No. 2 described in this Joint Proxy Statement/Prospectus.

IF YOU CANNOT BE PRESENT AT THE MEETINGS, 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 MERGER

THIS AGREEMENT AND PLAN OF MERGER (the “Agreement”) is made as of this [●] day of November, 2023, by and among Nuveen AMT-Free Quality Municipal Income Fund (the “Acquiring Fund”), Nuveen Massachusetts Quality Municipal Income Fund (the “Target Fund”), each a Massachusetts business trust, and [●] Merger Sub, LLC (the “Merger Sub”), a Massachusetts limited liability company and a direct, wholly-owned subsidiary of the Acquiring Fund. The Acquiring Fund and the Merger Sub may be referred to herein together as the “Acquiring Fund Parties.” The Acquiring Fund and the Target Fund may be referred to herein as a “Fund” and, collectively, as the “Funds.”

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 the Target Fund into the Acquiring Fund will consist of the merger of the Target Fund with and into the Merger Sub pursuant to which shareholders of the Target Fund (collectively, “Target Fund Shareholders”) will receive (i) with respect to holders of the issued and outstanding common shares of beneficial interest of the Target Fund (“Target Fund Common Shares”), newly issued common shares of beneficial interest, par value $0.01 per share, of the Acquiring Fund (the “Acquiring Fund Common Shares”) and (ii) with respect to holders of any issued and outstanding Series 1 Variable Rate Demand Preferred Shares (“VRDP Shares”) of the Target Fund (the “Target Fund VRDP Shares” and, collectively with the Target Fund Common Shares, the “Target Fund Shares”), newly issued Series 6 VRDP Shares (or such other series designation as is deemed appropriate by the officers of the Acquiring Fund) of the Acquiring Fund with a par value of $0.01 per share and liquidation preference of $100,000 per share (the “Acquiring Fund VRDP Shares” and, collectively with the Acquiring Fund Common Shares, the “Acquiring Fund Shares”) as provided herein, all upon the terms and conditions set forth in this Agreement (the “Merger”).

ARTICLE I

MERGER

1.1   MERGER. Subject to the terms and conditions contained herein and on the basis of the representations and warranties contained herein, and in accordance with Section 2 of Chapter 182 of the Massachusetts General Laws (“M.G.L.”) and Section 59 of the M.G.L. Chapter 156C, at the Effective Time (as

A-1

defined in Section 3.1), the Target Fund shall be merged with and into the Merger Sub, the separate existence of the Target Fund shall cease and the Merger Sub shall be the surviving company in the Merger (sometimes referred to herein as the “Surviving Company”) in accordance with such laws and shall continue as a wholly-owned subsidiary of the Acquiring Fund. The separate limited liability company existence of the Merger Sub shall continue unaffected and unimpaired by the Merger and, as the Surviving Company, it shall be governed by the laws of the Commonwealth of Massachusetts.

(a)   At the Effective Time, as a result of the Merger and without any action on the part of the holder of any shares of the Target Fund:

(i)   Each Target Fund Common Share issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the number of Acquiring Fund Common Shares provided for in Section 2.2 (with cash being distributed in lieu of fractional Acquiring Fund Common Shares as set forth in Section 2.2);

(ii)   The Target Fund VRDP Shares issued and outstanding immediately prior to the Effective Time, if any, shall, by virtue of the Merger and without any action on the part of the holder(s) thereof, be converted on a one-for-one basis into Acquiring Fund VRDP Shares having (a) substantially similar terms to the Target Fund VRDP Shares as of the Closing (as defined in Section 3.1), (b) equal priority 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 (c) 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 common shares of the Acquiring Fund; and

(iii)   The membership interests in the Merger Sub issued and outstanding immediately prior to the Effective Time shall remain unchanged as a result of the Merger and shall remain as the only issued and outstanding membership interests of the Surviving Company.

(b)   The certificate of organization of the Merger Sub as in effect immediately prior to the Effective Time (the “Certificate of Organization”) shall be the certificate of organization of the Surviving Company, unless and until amended in accordance with its terms and applicable law. The operating agreement of the Merger Sub in effect immediately prior to the Effective Time (the “LLC Agreement”) shall be the operating agreement of the Surviving Company unless and until amended in accordance with its terms and applicable law.

(c)   At the Effective Time, the separate legal existence of the Target Fund shall cease for all purposes and the Merger Sub shall continue in existence as the Surviving Company, and without any further action being required, the Surviving Company shall succeed to and possess all of the rights, privileges and powers of the Merger Sub and the Target Fund, and all of the assets and property of whatever kind and character of the Merger Sub and the Target Fund shall vest in the Merger Sub without further act or deed. At the Effective Time, the Surviving Company shall be liable for all of the liabilities and obligations of the Merger Sub and the Target Fund, and any claim or judgment against the Merger Sub or the Target Fund may be enforced against the Surviving Company, in accordance with applicable law.

(d)   The Acquiring Fund will issue Acquiring Fund Shares to Target Fund Shareholders upon the conversion of Target Fund Shares by opening shareholder accounts on the share ledger records of the Acquiring Fund in the names of and in the amounts due to the Target Fund Shareholders based on (i) with respect to holders of the issued and outstanding Target Fund Common Shares, their holdings of Target Fund Common Shares as of immediately prior to the Effective Time, and (ii) with respect to holders of any issued and outstanding Target Fund VRDP Shares, the number of Target Fund VRDP Shares held by such shareholder immediately prior to the Effective Time. Ownership of Acquiring Fund Shares will be shown on the books of the

A-2

applicable transfer agent or tender and paying agent, as applicable, for the Acquiring Fund, and the Acquiring Fund will not issue certificates representing Acquiring Fund Shares in connection with the Merger, except for any global share certificate or certificates required by a securities depository in connection with the establishment of book-entry ownership of the Acquiring Fund Common Shares or the Acquiring Fund VRDP Shares. All Acquiring Fund Shares to be issued pursuant to the Merger shall be deemed issued and outstanding as of the Effective Time.

(e)   Upon the terms and subject to the conditions of this Agreement, the parties shall cause the filing of one or more certificates of merger (a “Certificate of Merger”) with the Secretary of the Commonwealth of Massachusetts in accordance with the laws of the Commonwealth of Massachusetts.

(f)   The Target Fund agrees to dispose of certain assets prior to the Closing, but only if and to the extent necessary, so that at the Closing, when the assets of the Target Fund are aggregated with the Acquiring Fund’s assets, the resulting portfolio will meet the Acquiring Fund’s investment objective, policies and restrictions, as set forth in the Acquiring Fund’s Registration Statement (as defined in Section 5.5). Notwithstanding the foregoing, nothing herein will require the Target Fund to dispose of any investments or securities if, in the reasonable judgment of the Target Fund Board or Nuveen Fund Advisors, LLC, the investment adviser to the Fund (the “Adviser”), such disposition would adversely affect the status of the Merger as a “reorganization” as such term is used in Section 368(a) of the Code or would otherwise not be in the best interests of the Target Fund.

1.2   DISSOLUTION, LIQUIDATION AND TERMINATION. As soon as practicable after the Effective Time, the Merger Sub shall be dissolved and the Acquiring Fund will assume all of the Merger Sub’s liabilities and obligations, known and unknown, contingent or otherwise, whether or not determinable, and the Merger Sub will distribute to the Acquiring Fund, which will be the sole member of the Merger Sub at such time, all of the assets of the Merger Sub in complete liquidation of its interest in the Merger Sub in accordance with a Plan of Dissolution adopted by the Merger Sub.

1.3   ACCOUNTING AND PERFORMANCE SURVIVOR. In connection with the transactions contemplated by this Agreement, notwithstanding that the Merger Sub shall be the surviving entity in the Merger, the Acquiring Fund shall be deemed the survivor solely for accounting and performance record purposes.

1.4   DECLARATION OF PREFERRED SHARE DIVIDENDS. Dividends shall accumulate on any issued and outstanding Target Fund VRDP Shares up to and including the day immediately preceding the Closing Date (as defined in Section 3.1) and then cease to accumulate, and dividends on the Acquiring Fund VRDP Shares will accumulate from and including the Closing Date. Prior to the Valuation Time (as defined in Section 2.1), the Target Fund will declare all accumulated but unpaid dividends on such Target Fund VRDP Shares up to and including the day immediately preceding the Closing Date. With respect to any issued and outstanding Target Fund VRDP Shares, such dividends will be paid by the Target Fund from its own funds, and not from amounts advanced by, borrowed from, or reimbursed by the Acquiring Fund, on the Closing Date, but prior to the Closing, to holders thereof as of the day immediately preceding the Closing Date (or, if such day is not a business day, the next preceding business day).

1.5   TRANSFER TAXES. Any transfer taxes payable upon the issuance of Acquiring Fund Shares in a name other than a registered holder of Target Fund Shares on the books of the Target 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.

1.6   REPORTING. Any reporting responsibility of the Target Fund, including, without limitation, the responsibility for filing of regulatory reports, tax returns or other documents with the Securities and Exchange Commission (the “Commission”) or other regulatory authority, the exchange on which the Target 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 the Target Fund or its duly appointed agent.

A-3

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

ARTICLE II

VALUATION

2.1   VALUATION OF SHARES. The net asset value per share of the Target Fund Common Shares and the net asset value per share of the Acquiring Fund Common Shares shall be computed as of the close of regular trading on the New York Stock Exchange 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 or such other valuation procedures as shall be mutually agreed upon by the parties (and approved by the Target Fund Board and the Acquiring Fund Board).

2.2   COMMON SHARES TO BE ISSUED. As of the Effective Time, each Target Fund Common Share outstanding immediately prior to the Effective Time shall be converted into a number of Acquiring Fund Common Shares equal to one multiplied by the quotient of the net asset value per share of a Target Fund Common Share divided by the net asset value per share of an Acquiring Fund Common Share, each as determined as of the Valuation Time in accordance with Section 2.1. The aggregate net asset value of Acquiring Fund Common Shares received by Target Fund common shareholders (the “Target Fund Common Shareholders”) in the Merger (including any fractional share interests to which they would be entitled) will equal, as of the Valuation Time, the aggregate net asset value of the Target Fund Common Shares held by the Target Fund Common Shareholders as of such time. No fractional Acquiring Fund Common Shares will be distributed to Target Fund Common Shareholders and, in lieu of such fractional shares, Target Fund Common Shareholders will receive cash. In the event Target Fund Common Shareholders would be entitled to receive fractional Acquiring Fund Common Shares, the Acquiring Fund’s transfer agent will aggregate all such fractional common shares and sell the resulting whole shares on the exchange on which such shares are listed for the account of all such Target Fund Common Shareholders, and each such Target Fund Common Shareholder 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 transfer agent for the Acquiring Fund’s common shares will act directly on behalf of the Target Fund Common 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 the Target Fund Common Shareholders entitled to receive the fractional shares (without interest and subject to withholding taxes).

2.3   EFFECT OF SUSPENSION IN TRADING. In the event that at the Valuation Time an accurate appraisal of the net asset value per share of the Acquiring Fund or the Target Fund is impracticable due to either: (a) the closure of, or the imposition of a trading restriction on, the exchange on which shares of a Fund are listed or another exchange on which the portfolio securities of the Acquiring Fund or the Target Fund are purchased or sold; or (b) a disruption in trading or the reporting of trading on the exchange on which shares of a Fund are listed or elsewhere, the Closing Date may be postponed until at least the first business day after the day on which trading is fully resumed and/or reporting is restored or such later time as the parties may agree pursuant to Section 3.1.

2.4   COMPUTATIONS OF NET ASSET VALUE. Subject to Section 2.1 above, 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 in accordance with its regular practice as custodian of the Funds.

(b)   The Acquiring Fund shall issue and deliver, or cause the transfer agent, or tender and paying agent, as applicable, with respect to the Acquiring Fund Common Shares and Acquiring Fund VRDP Shares, as applicable, to issue and deliver, to the Target Fund a confirmation evidencing the Acquiring Fund Shares to be credited at the Closing to the shareholders of the Target Fund or provide evidence satisfactory to the Target Fund that such Acquiring Fund Shares have been credited to the account of the shareholders of the Target Fund on the books of the Acquiring Fund.

3.4   DELIVERY OF ADDITIONAL ITEMS. At the Closing, each party shall deliver to the other party or parties such bills of sale, checks, assignments, assumptions of liability, share certificates, opinions, receipts and other documents or instruments, if any, as such other parties or their counsel may reasonably request to effect the transactions contemplated by this Agreement.

The Acquiring Fund will call a meeting of its preferred shareholders and the Target Fund will call a meeting of its common and preferred shareholders, to consider and act upon the proposal or proposals required to effect the provisions of this Agreement and to take all other appropriate actions necessary to obtain approval of the transactions contemplated herein.

A-10

5.3   ADDITIONAL INFORMATION. The Target Fund will assist the Acquiring Fund in obtaining such information as the Acquiring Fund reasonably requests concerning the beneficial ownership of the Target Fund’s shares.

5.4   FURTHER ACTION. Subject to the provisions of this Agreement, each Fund and the Merger Sub will take or cause to be taken all actions, and do or cause to be done all things, reasonably necessary, proper or advisable to consummate and make effective the transactions contemplated by this Agreement, including any actions required to be taken after the Closing.

5.5   PREPARATION OF REGISTRATION STATEMENT AND PROXY MATERIALS. The Funds will prepare and file with the Commission a registration statement on Form N-14 relating to the Acquiring Fund Common Shares to be issued to Target Fund Common Shareholders and the approval of the Merger and/or related matters by the common shareholders of the Target Fund and preferred shareholders of the Acquiring Fund (the “Registration Statement”), and a proxy statement relating to the Acquiring Fund VRDP Shares to be issued to holders of Target Fund VRDP Shares and the approval of the Merger by the holders of Target Fund VRDP Shares (the “VRDP Proxy Statement”). The Registration Statement shall include a proxy statement of the Funds and a prospectus of the Acquiring Fund relating to the transactions contemplated by this Agreement, as applicable (the “Joint Proxy Statement/Prospectus”). The Registration Statement and the VRDP Proxy Statement shall be in compliance with the 1933 Act, the Securities Exchange Act of 1934, as amended, and the 1940 Act, as applicable.

5.6   REGULATORY APPROVALS. The Acquiring Fund will use all reasonable efforts to obtain the approvals and authorizations required by the 1933 Act, the 1940 Act, the listing rules of the New York Stock Exchange or another national securities exchange and such of the state “blue sky” or securities laws as it may deem appropriate in order to consummate the transactions hereunder.

5.7   TAX STATUS OF MERGER. The intention of the parties is that the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Neither Fund nor the Merger Sub shall take any action, or cause any action to be taken (including, without limitation, the filing of any tax return), that is inconsistent with such treatment or that results in the failure of the transactions to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. At or prior to the Closing, the parties to this Agreement will take such action, or cause such action to be taken, as is reasonably necessary to enable counsel to render the tax opinion contemplated in Section 8.9.

(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 under

its Declaration of Trust and Massachusetts law applicable to business trusts to conduct its business as described in the definitive Joint Proxy Statement/Prospectus as filed with the Commission pursuant to Rule 497 under the 1933 Act.

(b)   The Merger Sub has been formed as a limited liability company and is existing under the laws of the Commonwealth of Massachusetts.

(d)   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 the Target Fund on behalf of the Target 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 definitive Joint Proxy Statement/Prospectus as filed with the Commission pursuant to Rule 497 under the 1933 Act, shareholders of the Acquiring Fund may under certain circumstances, be held personally liable for its obligations under the laws of the Commonwealth of Massachusetts, 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 or By-Laws or the laws of the Commonwealth of Massachusetts.

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

(f)   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 or the Merger Sub of the transactions contemplated hereby, except as have been obtained, and except as may be required under any Massachusetts securities law, statute, rule or regulation, about which such counsel expresses no opinion.

(g)   The execution and delivery of this Agreement by the Acquiring Fund and the Merger Sub did not, and the consummation by the Acquiring Fund and the Merger Sub of the transactions contemplated herein will not, violate the Acquiring Fund’s Declaration of Trust, By-Laws or, if the Acquiring Fund has any issued and outstanding preferred shares as of the Closing, any Acquiring Fund MFP Statement, any Acquiring Fund VRDP Statement or any Acquiring Fund AMTP Statement (assuming the requisite approval of the Acquiring Fund’s shareholders has been obtained in accordance with the requirements of the Acquiring Fund’s Declaration of Trust and By-Laws and each Acquiring Fund MFP Statement, each Acquiring Fund VRDP Statement and each Acquiring Fund AMTP Statement) or the Merger Sub’s Certificate of Organization or LLC Agreement, respectively.

Insofar as the opinions expressed above relate to or are dependent upon matters that are governed by the laws of the Commonwealth of Massachusetts, Vedder Price P.C. may rely on the opinions of Morgan, Lewis & Bockius LLP.

8.8   The Acquiring Fund shall have received (i) an opinion from Vedder Price P.C., special counsel to the Target Fund, and (ii) an opinion from Morgan, Lewis & Bockius LLP, with respect to matters governed by the laws of the Commonwealth of Massachusetts, each dated as of the Closing Date, substantially to the effect that:

(a)   The Target 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 under its Declaration of Trust and Massachusetts law applicable to business trusts to conduct its business as described in the definitive Joint Proxy Statement/Prospectus as filed with the Commission pursuant to Rule 497 under the 1933 Act.

A-14

(b)   The Target 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.

(e)   The execution and delivery of this Agreement by the Target Fund did not, and the consummation by the Target Fund of the transactions contemplated herein will not, violate the Target Fund’s Declaration of Trust, By-Laws or, if the Target Fund has any issued and outstanding VRDP Shares as of the Closing, the Target Fund VRDP Statement (assuming the requisite approval of the Target Fund’s shareholders has been obtained in accordance with the requirements of the Target Fund’s Declaration of Trust, By-Laws and the Target Fund VRDP Statement).

Insofar as the opinions expressed above relate to or are dependent upon matters that are governed by the laws of the Commonwealth of Massachusetts, Vedder Price P.C. may rely on the opinions of Morgan, Lewis & Bockius LLP.

8.9   The Funds shall have received an opinion of Vedder Price P.C., dated as of the Closing Date and addressed to the Acquiring Fund and the Target Fund, substantially to the effect that for federal income tax purposes:

(a)   The merger of the Target Fund with and into the Merger Sub pursuant to applicable state laws will constitute a “reorganization” within the meaning of Section 368(a) of the Code and the Acquiring Fund and the Target Fund will each be a “party to a reorganization,” within the meaning of Section 368(b) of the Code with respect to the merger.

(b)   No gain or loss will be recognized by the Acquiring Fund or the Merger Sub upon the merger of the Target Fund with and into the Merger Sub pursuant to applicable state laws or upon the liquidation of the Merger Sub.

(c)   No gain or loss will be recognized by the Target Fund upon the merger of the Target Fund with and into the Merger Sub pursuant to applicable state laws.

(d)   No gain or loss will be recognized by the Target Fund Shareholders upon the conversion of all their Target Fund Shares solely into Acquiring Fund Shares in the merger of the Target Fund with and into the Merger Sub pursuant to applicable state laws, except to the extent the Target Fund Common Shareholders receive cash in lieu of a fractional Acquiring Fund Common Share.

(e)   The aggregate basis of the Acquiring Fund Shares received by each Target Fund Shareholder pursuant to the merger (including any fractional Acquiring Fund Common Share to which a Target Fund Common Shareholder would be entitled) will be the same as the aggregate basis of the Target Fund Shares that were converted into such Acquiring Fund Shares.

(f)   The holding period of the Acquiring Fund Shares received by each Target Fund Shareholder in the merger (including any fractional Acquiring Fund Common Share to which a Target Fund

A-15

Common Shareholder would be entitled) will include the period during which the shares of the Target Fund that were converted into such Acquiring Fund Shares were held by such shareholder, provided the Target Fund shares are held as capital assets at the time of the merger.

(g)   The basis of the Target Fund’s assets received by the Merger Sub in the merger will be the same as the basis of such assets in the hands of the Target Fund immediately before the merger.

(h)   The holding period of the assets of the Target Fund received by the Merger Sub in the merger will include the period during which those assets were held by the Target Fund.

No opinion will be expressed as to (1) the effect of the Merger on the Target Fund, the Acquiring Fund, the Merger Sub or any Target Fund Shareholder with respect to any asset (including, without limitation, any stock held in a passive foreign investment company as defined in Section 1297(a) of the Code) as to which any gain or loss is required to be recognized under federal income tax principles (a) at the end of a taxable year (or on the termination thereof) or (b) upon the transfer of such asset regardless of whether such transfer would otherwise be a non-taxable transaction under the Code, (2) the effect of the Merger under the alternative minimum tax imposed under Section 55 of the Code on any direct or indirect shareholder of the Target Fund that is a corporation, and (3) any other federal tax issues (except those set forth above) and all state, local or foreign tax issues of any kind. Such opinions will be based on customary assumptions and such representations as Vedder Price P.C. may reasonably request of the Funds and the Merger Sub. The Target Fund and the Acquiring Fund Parties will cooperate to make and certify the accuracy of such representations. Notwithstanding anything herein to the contrary, neither Fund may waive the conditions set forth in this Section 8.9. Insofar as the opinions expressed above relate to or are dependent upon the classification of the Acquiring Fund VRDP Shares as equity for federal income tax purposes, Vedder Price P.C. may rely on the opinions delivered to the Acquiring Fund by Stradley Ronon Stevens & Young, LLP with respect to such issue.

ARTICLE IX

EXPENSES

9.1   The expenses incurred in connection with the Merger (whether or not the Merger is consummated) will be allocated among and borne by the Funds ratably based on the projected relative benefits to the common shareholders of each Fund, as common shareholders of the Acquiring Fund for a period equal to shareholders’ average holding period of shares for each Fund, and such estimated amounts shall be set forth in the Registration Statement or other Proxy Materials. Each Fund shall have accrued such expenses as liabilities at or before the Valuation Time. Merger-related expenses include, without limitation, (a) expenses associated with the preparation and filing of the Registration Statement and other Proxy Materials; (b) postage; (c) printing; (d) accounting fees; (e) legal fees; (f) proxy solicitation costs; and (g) other related administrative or operational costs.

In addition, either Fund may at its option terminate the Agreement at or before the Closing due to:

(a)   a breach by the non-terminating party of any representation or warranty, or agreement to be performed at or before the Closing, if not cured within 30 days of the breach and prior to the Closing;

(b)   a condition precedent to the obligations of the terminating party that has not been met or waived and it reasonably appears that it will not or cannot be met; or

(c)   a determination by the Target Fund Board or the Acquiring Fund Board that the consummation of the transactions contemplated herein is not in the best interests of its respective Fund.

11.2   In the event of any such termination, in the absence of willful default, there shall be no liability for damages on the part of the Acquiring Fund Parties or the Target Fund. Notwithstanding any other provision of this Agreement to the contrary, the termination of this Agreement with respect to a Fund will have no effect on the obligation of that Fund to bear the portion of Merger-related expenses allocated to it as provided in Section 9.1.

ARTICLE XII

AMENDMENTS

12.1   This Agreement may be amended, modified or supplemented in such manner as may be mutually agreed upon in writing by the officers of each party affected by the amendment subject to the prior review of each such Fund’s counsel and the authorization of each such Fund’s Board of Trustees; provided, however, that following the meeting of the shareholders of the Target Fund called by such Fund pursuant to Section 5.2 of this Agreement, 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 Target Fund Shareholders under this Agreement to the detriment of such shareholders without their further approval.

(a) | Total Return Based on Common Share NAV is the combination of changes in common share NAV, reinvested dividend income at NAV and reinvested capital gains distributions at NAV, 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 NAV. 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 NAV), and therefore may be different from the price used in the calculation. Total returns are not annualized.

| Total Return Based on Common Share Price 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.

(b) | • Net Investment Income (Loss) ratios reflect income earned and expenses incurred on assets attributable to preferred shares issued by the Fund, where applicable.

• The expense ratios reflect, among other things, all interest expenses and other costs related to preferred 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, as follows:

(c) | Portfolio Turnover Rate is calculated based on the lesser of long-term purchases or sales divided by the average long-term market value during the period.

(d) | Aggregate Amount Outstanding: Aggregate amount outstanding represents the liquidation preference as of the end of the relevant fiscal year.

(e) | Asset Coverage Per $100,000: Asset coverage per $100,000 is calculated by subtracting the Fund’s liabilities and indebtedness not represented by senior securities from the Fund’s total assets, dividing the result by the aggregate amount of the Fund’s senior securities representing indebtedness then outstanding (if applicable), plus the aggregate of the involuntary liquidation preference of the outstanding preferred shares, if applicable, and multiplying the result by 100,000.

(a) | 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.

| Total Return Based on Common Share Price 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.

(b) | • Net Investment Income (Loss) ratios reflect income earned and expenses incurred on assets attributable to preferred shares issued by the Fund, where applicable.

• The expense ratios reflect, among other things, all interest expense and other costs related to preferred 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, as follows:

(c) | Portfolio Turnover Rate is calculated based on the lesser of long-term purchases or sales divided by the average long-term market value during the period.

(d) | Aggregate Amount Outstanding: Aggregate amount outstanding represents the liquidation preference as of the end of the relevant fiscal year and does not included any preferred shares noticed for redemption as noted on the Statement of Assets and Liabilities, where applicable.

(e) | Asset Coverage Per $100,000: Asset coverage per $100,000 is calculated by subtracting the Fund’s liabilities and indebtedness not represented by senior securities from the Fund’s total assets, dividing the result by the aggregate amount of the Fund’s senior securities representing indebtedness then outstanding (if applicable), plus the aggregate of the involuntary liquidation preference of the outstanding preferred shares, if applicable, and multiplying the result by 100,000.

(f) | Asset Coverage Per $1,000: Asset coverage per $1,000 is calculated by subtracting the Fund’s liabilities and indebtedness not represented by senior securities from the Fund’s total assets, dividing the result by the aggregate amount of the Fund’s senior securities representing indebtedness then outstanding (if applicable), plus the aggregate of the involuntary liquidation preference of the outstanding preferred shares, if applicable, and multiplying the result by 1,000.

(g) | The Ending and Average Market Value Per Share for each Series of the Fund’s MTP Shares outstanding were as follows:

INVESTMENT OBJECTIVES AND POLICIES

The following information 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” or as otherwise noted, are not fundamental policies and may be changed by a Fund’s Board of Trustees (each, a “Board” or the “Board,” and each trustee, a “Board Member”), without the approval of shareholders.

The Funds have similar investment objectives, policies and risks, but there are differences. Each Fund seeks to provide current income exempt from regular federal income tax. Each Fund also seeks to enhance portfolio value relative to the municipal bond market by investing in tax-exempt municipal securities that the Fund’s investment adviser believes are underrated or undervalued or that represent municipal market sectors that are undervalued. However, the Acquiring Fund is a national municipal fund that seeks to provide current income exempt from regular federal income tax and the federal alternative minimum tax applicable to individuals, while the Target Fund is a state bond fund investing primarily in a single state’s municipal obligations.

The Target Fund’s primary investment objective is to provide, through investment in a professionally managed portfolio of tax-exempt municipal obligations, current income exempt from both regular federal income taxes and Massachusetts personal income taxes, consistent with the Fund’s investment policies. The secondary investment objective of the Target Fund is the enhancement of portfolio value relative to the Massachusetts municipal bond market through investments in tax-exempt Massachusetts municipal obligations that, in the opinion of the Adviser, are underrated or undervalued or that represent municipal market sectors that are undervalued. As a fundamental policy, under normal circumstances, the Target Fund will invest at least 80% of its Assets (as defined below) in municipal securities and other related investments the income from which is exempt from regular federal and Massachusetts income taxes. As a non-fundamental policy, under normal circumstances, the Target Fund will invest at least 80% of its Managed Assets (as defined below) in securities that at the time of investment are investment grade quality. A security is considered investment grade quality if it is rated within the four highest letter grades (Baa or BBB or better) by at least one NRSRO that rates such security (even if it is rated lower by another), or if it is unrated by any NRSRO but judged to be of comparable quality by the Fund’s sub-adviser. Under normal circumstances, the Target 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 by any NRSRO but judged to be of comparable quality by the Target Fund’s sub-adviser. No more than 10% of the Target 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 sub-adviser.

The Acquiring Fund’s investment objectives are to provide current income exempt from regular federal income tax and the federal alternative minimum tax applicable to individuals, and to enhance portfolio value relative to the municipal bond market by investing in tax-exempt municipal securities that the Adviser believes are underrated or undervalued or that represent municipal market sectors that are undervalued. As a fundamental investment policy, under normal circumstances, the Acquiring Fund will invest at least 80% of its Assets in municipal securities and other related investments the income from which is exempt from regular federal income taxes. Additionally, as a fundamental investment policy, under normal circumstances, the Acquiring Fund will invest at least 80% of its Assets in a portfolio of securities, the income from which is exempt from the federal alternative minimum tax applicable to individuals. As a non-fundamental investment policy, under normal circumstances, the Acquiring Fund will invest 100% of its Managed Assets in municipal securities and other related investments the income from which is exempt from the federal alternative minimum tax applicable to individuals at the time of purchase. As a non-fundamental policy, under normal circumstances, the Acquiring Fund may invest up to 35% of its Managed Assets in securities rated, at the time of investment, below the three highest grades (Baa or BBB or lower) by at least one NRSRO, which includes below investment grade securities or unrated securities judged to be of comparable quality by the Fund’s sub-adviser. The Acquiring Fund may invest in distressed securities but may not invest in the securities of an issuer which, at the time of investment, is in default on its obligations to pay principal or interest thereon when due or that is involved in a bankruptcy

S-1

proceeding (i.e., rated below C-, at the time of investment); provided, however, that the Fund’s sub-adviser may determine that it is in the best interest of shareholders in pursuing a workout arrangement with issuers of defaulted securities to make loans to the defaulted issuer or another party, or purchase a debt, equity or other interest from the defaulted issuer or another party, or take other related or similar steps involving the investment of additional monies, but only if that issuer’s securities are already held by the Fund.

Both the Target Fund and the Acquiring Fund emphasize investments in municipal securities with long-term maturities. Both Funds will generally maintain an investment portfolio with an overall weighted average maturity of greater than 10 years. As a result, each Fund’s portfolio may include long-term and intermediate-term municipal securities.

Each Fund defines “Assets” as the net assets of the Fund plus the amount of any borrowings for investment purposes. Each Fund defines “Managed Assets” as the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of generally accepted accounting principles), and derivatives will be valued at their market value.

With respect to the Target Fund, under normal circumstances:

| • |  | The Target Fund will invest at least 80% of its Managed Assets in securities that at the time of investment are investment grade quality. A security is considered investment grade quality if it is rated within the four highest letter grades (Baa or BBB or better) by at least one NRSRO that rates such security (even if it is rated lower by another), or if it is unrated by any NRSRO but judged to be of comparable quality by the Fund’s sub-adviser.

| • |  | The Target Fund may invest up to 20% of its Managed Assets in municipal securities that at the time of investment are rated below investment grade (Ba or BB or lower) or are unrated by any NRSRO but judged to be of comparable quality by the Fund’s sub-adviser.

| • |  | No more than 10% of the Target 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 sub-adviser.

| • |  | The Target Fund may invest up to 20% of its Managed Assets in municipal securities that pay interest that is taxable under the federal alternative minimum tax applicable to individuals.

| • |  | The Target Fund may invest up to 15% of its net assets in inverse floating rate securities.

With respect to the Acquiring Fund, under normal circumstances:

| • |  | The Acquiring Fund may invest up to 35% of its Managed Assets in securities that, at the time of investment, are rated below the three highest grades (Baa or BBB or lower) by at least one NRSRO or are unrated but judged to be of comparable quality by the Fund’s sub-adviser.

PORTFOLIO COMPOSITION

The following information supplements the discussion of the Acquiring Fund’s investment objectives, principal investment strategies, policies and techniques that appears in the Joint Proxy Statement/Prospectus. Additional information concerning principal investment strategies of the Acquiring Fund, and other investment strategies that may be used by the Acquiring Fund, is set forth below.

References in this section to the Fund apply to the Acquiring Fund.

Municipal Securities

General. The 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 tax. Municipal securities are generally debt obligations issued by state and local governmental entities and may be issued by U.S. territories and possessions to finance or refinance public projects such as roads, schools, and water supply systems. Municipal securities may also be issued on behalf of private entities or 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 of the later issuance of 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 Fund may invest in municipal bonds issued by U.S. territories and possessions (such as Puerto Rico or Guam) the income from which is exempt from regular federal income tax. 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 securities 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.

Tobacco Settlement Bonds. The Fund may invest in tobacco settlement bonds, which are municipal securities that are backed solely by expected revenues to be derived from lawsuits involving tobacco related deaths and illnesses which were settled between certain states and U.S. tobacco companies. Tobacco settlement bonds are secured by an issuing state’s proportionate share in the Master Settlement Agreement (“MSA”). The MSA is an agreement, reached out of court in November 1998 between 46 states and nearly all of the U.S. tobacco manufacturers. The MSA provides for annual payments in perpetuity by the manufacturers to the states in exchange for releasing all claims against the manufacturers and a pledge of no further litigation. Tobacco manufacturers pay into a master escrow trust based on their market share, and each state receives a fixed percentage of the payment as set forth in the MSA. A number of states have securitized the future flow of those payments by selling bonds pursuant to indentures or through distinct governmental entities created for such purpose. The principal and interest payments on the bonds are backed by the future revenue flow related to the MSA. Annual payments on the bonds, and thus risk to the Fund, are highly dependent on the receipt of future settlement payments to the state or its governmental entity.

S-4

The actual amount of future settlement payments is further dependent on many factors, including, but not limited to, annual domestic cigarette shipments, reduced cigarette consumption, increased taxes on cigarettes, inflation, financial capability of tobacco companies, continuing litigation and the possibility of tobacco manufacturer bankruptcy. The initial and annual payments made by the tobacco companies will be adjusted based on a number of factors, the most important of which is domestic cigarette consumption. If the volume of cigarettes shipped in the United States by manufacturers participating in the settlement decreases significantly, payments due from them will also decrease. Demand for cigarettes in the United States could continue to decline due to price increases needed to recoup the cost of payments by tobacco companies. Demand could also be affected by anti-smoking campaigns, tax increases, reduced advertising, and enforcement of laws prohibiting sales to minors; elimination of certain sales venues such as vending machines; and the spread of local ordinances restricting smoking in public places. As a result, payments made by tobacco manufacturers could be negatively impacted if the decrease in tobacco consumption is significantly greater than the forecasted decline. A market share loss by the MSA companies to non-MSA participating tobacco manufacturers would cause a downward adjustment in the payment amounts. A participating manufacturer filing for bankruptcy also could cause delays or reductions in bond payments. The MSA itself has been subject to legal challenges and has, to date, withstood those challenges.

Municipal Leases and Certificates of Participation. The Fund 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 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, the Fund’s original investment. To the extent that the 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 Fund will purchase municipal securities representing lease obligations only where the Fund’s investment adviser, Nuveen Fund Advisors, LLC (“Nuveen Fund Advisors” or the “Adviser”), and/or the Fund’s sub-adviser, Nuveen Asset Management, LLC (“Nuveen Asset Management” or the “Sub-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 Fund with the right to a pro rata undivided interest in the underlying municipal securities. In addition, such participations generally provide the Fund with the right to demand payment, on not more than seven days’ notice, of all or any part of the 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

S-5

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. However, an investment in such instruments 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 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. The Fund’s distributions of its interest income from private activity bonds may subject certain investors to the federal alternative minimum tax.

Inverse Floating Rate Securities. The Fund may invest in inverse floating rate securities. Inverse floating rate securities 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, commonly referred to as a “tender option bond trust” (“TOB trust”), that holds municipal bonds. The TOB 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). Both classes of beneficial interests are represented by certificates or receipts. The floating rate securities have first priority on the cash flow from the municipal bonds held by the TOB trust. In this structure, the floating rate security holders have the option, at periodic short-term intervals, to tender their securities to the trust for purchase and to receive the face value thereof plus accrued interest. The obligation of the trust to repurchase tendered securities is supported by a remarketing agent and by a liquidity provider. As consideration for providing this support, the remarketing agent and the liquidity provider receive 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 trust is not obligated to purchase tendered short-term floaters in the event of certain defaults with respect to the underlying municipal bonds or a significant downgrade in the credit rating assigned to the bond issuer.

S-6

As the holder of an inverse floating rate investment, the Fund receives the residual cash flow from the TOB trust. Because the holder of the short-term floater is generally assured liquidity at the face value of the security plus accrued interest, 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 TOB 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 to the value of the inverse floaters that are issued by the TOB trust, and it 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 TOB trust are passed through, pro rata, to the holders of the short-term floaters and to the Fund as the holder of the associated inverse floaters.

Because any increases in the interest rate on the short-term floaters issued by a TOB trust would reduce the residual interest paid on the associated inverse floaters, and because fluctuations in the value of the municipal bond deposited in the TOB trust would affect only the value of the inverse floater and not the value of the short-term floater issued by the trust so long as the value of the municipal bond held by the trust exceeded the face amount of short-term floaters outstanding, the value of inverse floaters is generally more volatile than that of an otherwise comparable municipal bond held on an unleveraged basis outside a TOB trust. Inverse floaters generally will underperform the market of fixed-rate bonds in a rising interest rate environment (i.e., when bond values are falling), but they will tend to outperform the market of fixed-rate bonds when interest rates decline or remain relatively stable. Although volatile in value and return, 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 primarily upon the inverse floater holder’s ability to sell the underlying bonds deposited in the TOB trust at an attractive price.

The Fund may invest in inverse floating rate securities issued by TOB trusts in which the liquidity providers have recourse to the Fund pursuant to a separate shortfall and forbearance agreement. Such an agreement would require the Fund to reimburse the liquidity provider, among other circumstances, upon termination of the TOB trust for the difference between the liquidation value of the bonds held in the trust and the principal amount and accrued interest due to the holders of floating rate securities issued by the trust. The Fund will enter into such a recourse agreement (1) when the liquidity provider requires such a recourse agreement because the level of leverage in the TOB trust exceeds the level that the liquidity provider is willing to support absent such an agreement; and/or (2) to seek to prevent the liquidity provider from collapsing the trust in the event the municipal bond held in the trust has declined in value to the point where it may cease to exceed the face amount of outstanding short-term floaters. In an instance where the 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 plus accrued interest thereon.

The Fund may invest in both inverse floating rate securities and floating rate securities (as discussed below) issued by the same TOB trust.

Floating Rate Securities. The Fund may also invest in short-term floating rate securities, as described above, issued by TOB trusts. 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 other periods of up to one year. Since the tender option feature provides a shorter term than the final maturity or first call date of the underlying municipal bond deposited in the trust, the Fund, as the holder of the floating rate securities, relies upon the terms of the remarketing and liquidity agreements with the financial institution that acts as remarketing agent and/or liquidity provider 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 TOB trust and the application of the proceeds to pay off the floating rate securities. The TOB 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.

S-7

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.

London Interbank Offered Rate (“LIBOR”) Replacement. LIBOR is an index rate that historically was widely used as a reference rate for setting the floating interest rate on private loans and other financial products. The publication of U.S. dollar LIBOR as a representative reference rate ceased as of June 30, 2023, although the publication of synthetic 1-month, 3-month and 6-month U.S. dollar LIBOR will continue for a limited time for use in connection with a small number of legacy financial contracts that have not yet transitioned to the Secured Overnight Financing Rate (“SOFR”) or another replacement reference rate. SOFR and other replacement reference rates are relatively new, which may result in, among other things, increased volatility or illiquidity in markets for instruments that rely on such reference rates. Accordingly, it is difficult at this time to predict the full impact of the transition away from LIBOR to SOFR or other replacement reference rates.

Hedging Strategies and Other Uses of Derivatives

The Fund may use certain derivative instruments in pursuit of its investment objectives. Such instruments include financial futures contracts, forward contracts, swap contracts (including interest rate swaps, credit default swaps and municipal market date rate locks (“MMD Rate Locks”)), options on financial futures, options on swap contracts or other derivative instruments. The credit default swaps in which the Fund may invest include index credit default swaps (“CDX”) and single-name credit default swaps (“CDS”). A CDX is a portfolio of credit default swaps with similar characteristics, such as credit default swaps on high-yield bonds. Certain CDX indices are subject to mandatory central clearing and exchange trading, which may reduce counterparty credit risk and increase liquidity compared to other credit default swaps or CDX transactions. Unlike other types of credit default swaps, single-name CDS do not have the benefit of diversification across many issuers. Interest rate swaps involve the exchange by the 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. The 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 Fund 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. The Fund will value derivative instruments at market/fair value for purposes of calculating compliance with the Fund’s 80% investment policy in investments the income from which is exempt from regular federal income tax.

“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 Bloomberg Municipal Bond Index). Some forms of derivatives may trade on exchanges, while non-standardized derivatives,

S-8

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 Fund may be greater than gains in the value of the securities in the Fund’s portfolio. In addition, futures and options markets may not be liquid in all circumstances. As a result, in volatile markets, the Fund may not be able to close out the transaction without incurring losses substantially greater than the initial deposit. Finally, the potential deposit requirements in futures contracts create an ongoing greater potential financial risk than do options transactions, where the exposure is limited to the cost of the initial premium. Losses due to hedging transactions will reduce yield. Net gains, if any, from hedging and other portfolio transactions will be distributed as taxable distributions to shareholders. Successful implementation of most hedging strategies will generate taxable income.

The use of derivative instruments is subject to applicable regulations of the SEC, the CFTC, various state regulatory authorities and, with respect to exchange-traded derivatives, the several exchanges upon which they are traded. Under Rule 18f-4 under the Investment Company Act of 1940, as amended (the “1940 Act”), a registered investment company’s derivatives exposure, which includes short positions for this purpose, is limited through a value-at-risk test and Rule 18f-4 requires the adoption and implementation of a derivatives risk management program for certain derivatives users. However, subject to certain conditions, limited derivatives users (as defined in Rule 18f-4) are not subject to the full requirements of Rule 18f-4. Rule 18f-4 could limit the Fund’s ability to engage in certain derivatives transactions and/or increase the costs of such derivatives transactions, which could adversely affect the value or performance of the Fund. Moreover, there may be asset coverage requirements for certain arrangements. In order to engage in certain transactions in derivatives, the Fund may be required to hold offsetting positions or to hold cash or liquid securities in a segregated account or designated on the Fund’s books. Changes in the value of a derivative may also create margin delivery or settlement payment obligations for the Fund. In addition, the Fund’s ability to use derivative instruments may be limited by tax considerations.

The Fund will invest in these instruments only in markets believed by the Adviser and/or the Sub-Adviser to be active and sufficiently liquid.

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

Swap Transactions. The Fund may enter into total return, interest rate and credit default swap agreements and interest rate caps, floors and collars. The Fund may also enter into options on the foregoing types of swap agreements (“swap options”).

The Fund may enter into swap transactions for any purpose consistent with its investment objectives and strategies, such as for the purpose of attempting to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets, as a duration management technique, to attempt to reduce risk arising from the ownership of a particular instrument, or to gain exposure to certain sectors or markets in the most economical way possible.

Swap agreements are two party contracts entered into primarily by institutional investors for a specified period of time. In a standard swap transaction, two parties agree to exchange the returns (or differentials in rates

S-9

of return) earned or realized on a particular predetermined asset, reference rate or index. The gross returns to be exchanged or swapped between the parties are generally calculated with respect to a notional amount, e.g., the return on or increase in value of a particular dollar amount invested at a particular interest rate or in a basket of securities representing a particular index. The notional amount of the swap agreement generally is only used as a basis upon which to calculate the obligations that the parties to the swap agreement have agreed to exchange.

Some, but not all, swaps may be cleared, in which case a central clearing counterparty stands between each buyer and seller and effectively guarantees performance of each contract, to the extent of its available resources for such purpose. Uncleared swaps have no such protection; each party bears the risk that its direct counterparty will default.

Interest Rate Swaps, Caps, Collars and Floors. Interest rate swaps are bilateral contracts in which each party agrees to make periodic payments to the other party based on different referenced interest rates (e.g., a fixed rate and a floating rate) applied to a specified notional amount. The purchase of an interest rate floor entitles the purchaser, to the extent that a specified index falls below a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate floor. The purchase of an interest rate cap entitles the purchaser, to the extent that a specified index rises above a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate cap. Interest rate collars involve selling a cap and purchasing a floor or vice versa to protect the Fund against interest rate movements exceeding given minimum or maximum levels.

Depending on the state of interest rates in general, the Fund’s use of interest rate swaps could enhance or harm the overall performance of common shares. To the extent interest rates decline, the value of the interest rate swap could decline, and could result in a decline in the net asset value of common shares. In addition, if the counterparty to an interest rate swap defaults, the Fund would not be able to use the anticipated net receipts under the swap to offset the interest payments on borrowings or the dividend payments on any outstanding preferred shares. Depending on whether the Fund would be entitled to receive net payments from the counterparty on the swap, 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 common shares. In addition, at the time an interest rate swap transaction reaches its scheduled termination date, there is a risk that the Fund 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 common shares. The Fund could be required to prepay the principal amount of any borrowings. Such redemption or prepayment would likely result in the Fund seeking to terminate early all or a portion of any swap transaction. Early termination of a swap could result in a termination payment by or to the Fund.

Total Return Swaps. In a total return swap, one party agrees to pay the other the “total return” of a defined underlying asset during a specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. A total return swap may be applied to any underlying asset but is most commonly used with equity indices, single stocks, bonds and defined baskets of loans and mortgages. The Fund might enter into a total return swap involving an underlying index or basket of securities to create exposure to a potentially widely-diversified range of securities in a single trade. An index total return swap can be used by the Adviser and/or the Sub-Adviser to assume risk, without the complications of buying the component securities from what may not always be the most liquid of markets.

Credit Default Swaps. A credit default swap is a bilateral contract that enables an investor to buy or sell protection against a defined-issuer credit event. The Fund may enter into credit default swap agreements either as a buyer or a seller. The Fund may buy protection to attempt to mitigate the risk of default or credit quality deterioration in an individual security or a segment of the debt securities market to which it has exposure, or to take a “short” position in individual bonds or market segments which it does not own. The Fund may sell protection in an attempt to gain exposure to the credit quality characteristics of particular bonds or market segments without investing directly in those bonds or market segments.

S-10

As the buyer of protection in a credit default swap, the Fund would pay a premium (by means of an upfront payment or a periodic stream of payments over the term of the agreement) in return for the right to deliver a referenced bond or group of bonds to the protection seller and receive the full notional or par value (or other agreed upon value) upon a default (or similar event) by the issuer(s) of the underlying referenced obligation(s). If no default occurs, the protection seller would keep the stream of payments and would have no further obligation to the Fund. Thus, the cost to the Fund would be the premium paid with respect to the agreement. If a credit event occurs, however, the Fund may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. The Fund bears the risk that the protection seller may fail to satisfy its payment obligations.

If the Fund is a seller of protection in a credit default swap and no credit event occurs, the Fund would generally receive an up-front payment or a periodic stream of payments over the term of the swap. If a credit event occurs, however, generally the Fund would have to pay the buyer the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. As the protection seller, the Fund effectively adds leverage to its portfolio because, in addition to being subject to investment exposure on its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. Thus, the Fund bears the same risk as it would by buying the reference obligation(s) directly, plus the additional risks related to obtaining investment exposure through a derivative instrument discussed below under “—Risks Associated with Swap Transactions.”

MMD Rate Locks. An MMD Rate Lock permits the Fund to lock in a specified municipal interest rate for a portion of its portfolio to preserve a return on a particular investment or a portion of its portfolio as a duration management technique or to protect against any increase in the price of securities to be purchased at a later date. By using an MMD Rate Lock, the Fund can create a synthetic long or short position, allowing the Fund to select what the manager believes is an attractive part of the yield curve. The Fund will ordinarily use these transactions as a hedge or for duration or risk management although it is permitted to enter into them to enhance income or gain or to increase the Fund’s yield, for example, during periods of steep interest rate yield curves (i.e., wide differences between short term and long term interest rates).

Swap Options. A swap option is a contract that gives a counterparty the right (but not the obligation), in return for payment of a premium, to enter into a new swap agreement or to shorten, extend, cancel, or otherwise modify an existing swap agreement at some designated future time on specified terms. A cash-settled option on a swap gives the purchaser the right, in return for the premium paid, to receive an amount of cash equal to the value of the underlying swap as of the exercise date. The Fund may write (sell) and purchase put and call swap options. Depending on the terms of the particular option agreement, the Fund generally would incur a greater degree of risk when it writes a swap option than when it purchases a swap option. When the Fund purchases a swap option, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when the Fund writes a swap option, upon exercise of the option the Fund would become obligated according to the terms of the underlying agreement.

Risks Associated with Swap Transactions. The use of swap transactions is a highly specialized activity which involves strategies and risks different from those associated with ordinary portfolio security transactions.

Futures and Options on Futures. A futures contract is an agreement between two parties to buy and sell a security, index or interest rate (each a “financial instrument”) for a set price on a future date. Certain futures contracts, such as futures contracts relating to individual securities, call for making or taking delivery of the underlying financial instrument. However, these contracts generally are closed out before delivery by entering into an offsetting purchase or sale of a matching futures contract (same exchange, underlying financial instrument, and delivery month). Other futures contracts, such as futures contracts on interest rates and indices, do not call for making or taking delivery of the underlying financial instrument, but rather are agreements pursuant to which two parties agree to take or make delivery of an amount of cash equal to the difference between the value of the financial instrument at the close of the last trading day of the contract and the price at which the contract was originally written. These contracts also may be settled by entering into an offsetting futures contract.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract. Initially, the Fund will be required to deposit with the futures broker, known as a futures commission merchant (“FCM”), an amount of cash or securities equal to a varying specified percentage of the contract amount. This amount is known as initial margin. The margin deposit is intended to ensure completion of the contract. Minimum initial margin requirements are established by the futures exchanges and may be revised. In addition, FCMs may establish margin deposit requirements that are higher than the exchange minimums. Cash held in the margin account generally is not income producing. However, coupon bearing securities, such as Treasury securities, held in margin accounts generally will earn income and may generate taxable income for federal income tax purposes that would be includable in the taxable income of the Fund and, to the extent distributed, would be taxable to shareholders. Subsequent payments to and from the FCM, called variation margin, will be made on a daily basis as the price of the underlying financial instrument fluctuates, making the futures contract more or less valuable, a process known as marking the contract to market. Changes in variation margin are recorded by the Fund as unrealized gains or losses. At any time prior to expiration of the futures contract, the Fund may elect to close the position by taking an opposite position that will operate to terminate its position in the futures contract. A final determination of variation margin is then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a gain or loss. In the event of the bankruptcy or insolvency of an FCM that holds margin on behalf of the Fund, the Fund may be entitled to the return of margin owed to it only in proportion to the amount received by the FCM’s other customers, potentially resulting in losses to the Fund. Futures transactions also involve brokerage costs.

A futures option gives the purchaser of such option the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price at any time during the period of the option. Upon exercise of a call option, the purchaser acquires a long position in the futures contract and the writer is assigned the opposite short position. Upon the exercise of a put option, the opposite is true.

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 (“OTC”) transactions.

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.

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.

S-12

Index Options. The Fund 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.

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

Limitations on the Use of Futures, Options on Futures and Swaps. The Adviser has claimed, with respect to the Fund, the exclusion from the definition of “commodity pool operator” under the Commodity Exchange Act (“CEA”) provided by CFTC Regulation 4.5 and is therefore not currently subject to registration or regulation as such under the CEA with respect to the Fund. In addition, the Sub-Adviser has claimed the exemption from registration as a commodity trading advisor provided by CFTC Regulation 4.14(a)(8) and is therefore not currently subject to registration or regulation as such under the CEA with respect to the Fund. In February 2012, the CFTC announced substantial amendments to certain exemptions, and to the conditions for reliance on those exemptions, from registration as a commodity pool operator. Under amendments to the exemption provided under CFTC Regulation 4.5, if the Fund uses futures, options on futures, or swaps other than for bona fide hedging purposes (as defined by the CFTC), the aggregate initial margin and premiums on these positions (after taking into account unrealized profits and unrealized losses on any such positions and excluding the amount by which options that are “in-the-money” at the time of purchase are “in-the-money”) may not exceed 5% of the Fund’s net asset value, or alternatively, the aggregate net notional value of those positions may not exceed 100% of the Fund’s net asset value (after taking into account unrealized profits and unrealized losses on any such positions). The CFTC amendments to Regulation 4.5 took effect on December 31, 2012, and the Fund intends to comply with amended Regulation 4.5’s requirements such that the Adviser will not be required to register as a commodity pool operator with the CFTC with respect to the Fund. The Fund reserves the right to employ futures, options on futures and swaps to the extent allowed by CFTC regulations in effect from time to time and in accordance with the Fund’s policies. However, the requirements for qualification as a “regulated investment company” under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), may limit the extent to which the Fund may employ futures, options on futures or swaps.

Short-Term Investments

Short-Term Taxable Fixed-Income Securities. For temporary defensive purposes or to keep cash on hand fully invested, the Fund may invest any percentage of its managed assets in cash equivalents and short-term taxable fixed-income securities, although the 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 the dividends paid by the Fund 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:

| (1) | 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) 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 Valley Authority, whose securities are

S-13

| 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 and its agencies and instrumentalities do not guarantee the market value of their securities. Consequently, the value of such securities may fluctuate.

| (2) | 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 Federal Deposit Insurance Corporation regulations, the maximum insurance payable as to any one certificate of deposit is $250,000; therefore, certificates of deposit purchased by the Fund may not be fully insured.

| (3) | Repurchase agreements, which involve purchases of debt securities. At the time the 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 the 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 Fund to invest temporarily available cash. The Fund 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 Fund may invest. Repurchase agreements may be considered loans to the seller, collateralized by the underlying securities. The risk to the Fund 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 Fund is 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 Fund could incur a loss of both principal and interest. The 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 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 Fund. If the seller were to be subject to a federal bankruptcy proceeding, the ability of the Fund to liquidate the collateral could be delayed or impaired because of certain provisions of the bankruptcy laws.

| (4) | 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 Fund and a corporation. There is no secondary market for such notes. However, they are redeemable by the Fund 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 the 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 major NRSRO and which matures within one year of the date of purchase or carries 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

S-14

| 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.

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 Fund 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.

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, that are deemed to be illiquid and certain repurchase agreements with maturities in excess of seven days.

Other Investment Companies

The Fund may invest in securities of other open- or closed-end investment companies (including ETFs) that invest primarily in securities of the types in which the Fund may invest directly. As a shareholder in another

S-15

investment company, the Fund will bear its ratable share of that investment company’s expenses and would remain subject to payment of its own advisory and administrative fees with respect to assets so invested. Common shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies.

The Adviser and/or the Sub-Adviser will take expenses into account when evaluating the investment merits of an investment in an investment company relative to available investments. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to leverage risk. 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.

Exchange-Traded Funds. The Fund may invest in ETFs. ETFs are a type of index fund or actively-managed fund bought and sold on a securities exchange. An ETF trades like common stock and represents a portfolio of securities designed to track a particular market index. The Fund could purchase an ETF to gain exposure to all or a portion of the U.S. market, a foreign market, a region, a commodity, a currency, or to any other index that an ETF tracks. The risks of owning an ETF generally reflect the risks of owning the underlying securities they are designed to track, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs. An ETF may fail to accurately track the returns of the market segment or index that it is designed to track, and the price of an ETF’s shares may fluctuate. In addition, because they, unlike traditional mutual funds, are traded on an exchange, ETFs are subject to the following risks: (i) the performance of the ETF may not replicate the performance of the underlying index that it is designed to track; (ii) the market price of the ETF’s shares may trade at a premium or discount to the ETF’s net asset value; (iii) an active trading market for an ETF may not develop or be maintained; and (iv) there is no assurance that the requirements of the exchange necessary to maintain the listing of the ETF will continue to be met or remain unchanged. Trading in an ETF may be halted if the trading in one or more of the ETF’s underlying securities is halted, which could result in the ETF being more volatile. In the event substantial market or other disruptions affecting ETFs should occur in the future, the liquidity and value of the Fund’s shares could also be substantially and adversely affected.

Exchange-Traded Notes. The Fund may invest in exchange-traded notes (“ETNs”). ETNs are a type of senior, unsecured, unsubordinated debt security issued by financial institutions that combines both aspects of bonds and ETFs. An ETN’s returns are based on the performance of a market index minus fees and expenses. Similar to ETFs, ETNs are listed on an exchange and traded in the secondary market. However, unlike an ETF, an ETN can be held until the ETN’s maturity, at which time the issuer will pay a return linked to the performance of the market index to which the ETN is linked minus certain fees.

Unlike regular bonds, ETNs do not make periodic interest payments and principal is not protected. ETNs are subject to credit risk and the value of an ETN may drop due to a downgrade in the issuer’s credit rating, despite the underlying market benchmark or strategy remaining unchanged. The value of an ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, changes in the applicable interest rates, changes in the issuer’s credit rating, and economic, legal, political, or geographic events that affect the referenced underlying asset. When the Fund invests in ETNs it will bear its proportionate share of any fees and expenses borne by the ETN. The Fund’s decision to sell its ETN holdings may be limited by the availability of a secondary market. In addition, although an ETN may be listed on an exchange, the issuer may not be required to maintain the listing and there can be no assurance that a secondary market will exist for an ETN. ETNs are also subject to tax risk. No assurance can be given that the Internal Revenue Service (“IRS”) will accept, or a court will uphold, how the Fund characterizes and treats ETNs for federal income tax purposes.

Further, the IRS and Congress have considered proposals that would change the timing and character of income and gains from ETNs.

S-16

An ETN that is tied to a specific market benchmark or strategy may not be able to replicate and maintain exactly the composition and relative weighting of securities, commodities or other components in the applicable market benchmark or strategy. Some ETNs that use leverage can, at times, be relatively illiquid and, thus, they may be difficult to purchase or sell at a fair price. Leveraged ETNs are subject to the same risk as other instruments that use leverage in any form.

The market value of ETN shares may differ from their market benchmark or strategy. This difference in price may be due to the fact that the supply and demand in the market for ETN shares at any point in time is not always identical to the supply and demand in the market for the securities, commodities or other components underlying the market benchmark or strategy that the ETN seeks to track. As a result, there may be times when an ETN share trades at a premium or discount to its market benchmark or strategy.

Portfolio Trading and Turnover Rate

Portfolio trading may be undertaken to accomplish the investment objectives of the Fund 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 and/or the Sub-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 Fund may also engage to a limited extent in short-term trading consistent with its 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.

Subject to the foregoing, the Fund will attempt to achieve its investment objectives by prudent selection of municipal securities with a view to holding them for investment. While there can be no assurance thereof, the Fund anticipates that its annual portfolio turnover rate will generally not exceed 100%. However, the rate of turnover will not be a limiting factor when the Fund deems it desirable to sell or purchase securities. Therefore, depending upon market conditions, the annual portfolio turnover rate of the Fund may exceed 100% in particular years. A higher portfolio turnover rate would result in correspondingly greater brokerage commissions and other transactional expenses that are borne by the Fund. In addition, 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 or may result in greater amounts of net capital gain distributions. See “Federal Income Tax Matters.”

When-Issued and Delayed Delivery Transactions

The Fund may buy and sell 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. On such transactions, the payment obligation and the interest rate are fixed at the time the buyer enters into the commitment. Income generated by any liquid assets held to cover commitments to purchase securities on a when-issued and delayed-delivery basis which provide taxable income for federal income tax purposes is includable in the taxable income of the Fund and, to the extent distributed, will be taxable to shareholders. 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 cost.

Structured Notes

The 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”),

S-17

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.

Zero Coupon Bonds and Other Original Issue Discount Instruments

A zero coupon bond is a bond that typically 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, the holder receives the par value of the zero coupon bond, which generates a return equal to 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. This original issue discount (“OID”) approximates the total amount of interest the security will accrue and compound prior to its maturity and reflects the payment deferral and credit risk associated with the instrument. Because zero coupon securities and other OID instruments do not pay cash interest at regular intervals, the instruments’ ongoing accruals require ongoing judgments concerning the collectability of deferred payments and the value of any associated collateral. As a result, these securities may be subject to greater value fluctuations and less liquidity in the event of adverse market conditions than comparably rated securities that pay cash on a current basis. Because zero coupon bonds, and OID instruments generally, allow an issuer to avoid or delay the need to generate cash to meet current interest payments, they may involve greater payment deferral and credit risk than coupon loans and bonds that pay interest currently or in cash. The Fund generally will be required to distribute dividends to shareholders representing the income 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, the Fund may have to sell other investments, including when it may not be advisable to do so, and use the cash proceeds to make income distributions to its shareholders. For accounting purposes, these cash distributions to shareholders will not be treated as a return of capital.

Further, the Adviser collects management fees on the value of a zero coupon bond or OID instrument attributable to the ongoing noncash accrual of interest over the life of the bond or other instrument. As a result, the Adviser receives nonrefundable cash payments based on such noncash accruals while investors incur the risk that such noncash accruals ultimately may not be realized.

Inter-Fund Borrowing and Lending

The SEC has granted an exemptive order permitting the Nuveen registered open-end and closed-end funds, including the Fund, to participate in an inter-fund lending facility whereby those funds may directly lend to and borrow money from each other for temporary purposes (e.g., to satisfy redemption requests or when a sale of securities “fails,” resulting in an unanticipated cash shortfall) (the “Inter-Fund Program”). The closed-end Nuveen funds will participate only as lenders, and not as borrowers, in the Inter-Fund Program because such closed-end funds rarely, if ever, need to borrow cash to meet redemptions. The Inter-Fund Program is subject to a number of conditions, including, among other things, the requirements that (1) no fund may borrow or lend money through the Inter-Fund Program unless it receives a more favorable interest rate than is typically available from a bank or other financial institution for a comparable transaction; (2) no fund may borrow on an unsecured basis through the Inter-Fund Program unless the fund’s outstanding borrowings from all sources immediately after the inter-fund borrowing total 10% or less of its total assets; provided that if the borrowing fund has a secured borrowing outstanding from any other lender, including but not limited to another fund, the inter-fund loan must be secured on at least an equal priority basis with at least an equivalent percentage of collateral to loan

S-18

value; (3) if a fund’s total outstanding borrowings immediately after an inter-fund borrowing would be greater than 10% of its total assets, the fund may borrow through the inter-fund loan on a secured basis only; (4) no fund may lend money if the loan would cause its aggregate outstanding loans through the Inter-Fund Program to exceed 15% of its net assets at the time of the loan; (5) a fund’s inter-fund loans to any one fund shall not exceed 5% of the lending fund’s net assets; (6) the duration of inter-fund loans will be limited to the time required to receive payment for securities sold, but in no event more than seven days; and (7) each inter-fund loan may be called on one business days’ notice by a lending fund and may be repaid on any day by a borrowing fund. In addition, a Nuveen fund may participate in the Inter-Fund Program only if and to the extent that such participation is consistent with the fund’s investment objective and investment policies. The Board of Trustees of the Nuveen Funds is responsible for overseeing the Inter-Fund Program. The limitations detailed above and the other conditions of the SEC exemptive order permitting the Inter-Fund Program are designed to minimize the risks associated with Inter-Fund Program for both the lending fund and the borrowing fund. However, no borrowing or lending activity is without risk. When a fund borrows money from another fund, there is a risk that the loan could be called on one day’s notice or not renewed, in which case the fund may have to borrow from a bank at a higher rate or take other actions to payoff such loan if an inter-fund loan is not available from another fund. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.

Repurchase Agreements

As temporary investments, the Fund 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 the 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 to the Fund and, to the extent distributed, will be taxable to shareholders. See “Federal Income Tax Matters” below. The Fund will only enter into repurchase agreements with registered securities dealers or domestic banks that, in the opinion of the Adviser and/or the Sub-Adviser, present minimal credit risk. The risk to the Fund is limited to the ability of the issuer to pay the agreed-upon repurchase price on the delivery date; 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 Fund might incur a loss if the value of the collateral declines, and it 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 Fund may be delayed or limited. The Adviser and/or the Sub-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.

S-19

INVESTMENT RESTRICTIONS

In addition to (1) each Fund’s investment objectives; (2) the Acquiring Fund’s policy to invest, under normal circumstances, at least 80% of its Assets in municipal securities and other related investments the income from which is exempt from regular federal income taxes; (3) the Acquiring Fund’s policy to invest, under normal circumstances, at least 80% of its Assets in a portfolio of securities the income from which is exempt from the federal alternative minimum tax applicable to individuals; and (4) the Target Fund’s policy to invest, under normal circumstances, at least 80% of its Assets in municipal securities and other related investments the income from which is exempt from regular federal and Massachusetts income taxes, 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 as a single class, and of the holders of a majority of the outstanding preferred shares, voting separately as a single class. 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:

|  | Target Fund(1) |  | Acquiring Fund(1)
1. |  | Issue senior securities, as defined in the 1940 Act, other than preferred shares, except to the extent such issuance might be involved with respect to borrowings described under subparagraph (2) below or with respect to transactions involving futures contracts or the writing of options within the limits described in “Certain Trading Strategies of the Fund—Financial Futures and Options Transactions” and “Description of MuniPreferred—Asset Maintenance—MuniPreferred Basic Maintenance Amount”*. |  | Issue senior securities, as defined in the Investment Company Act of 1940, other than preferred shares, except to the extent permitted under the Investment Company Act of 1940 and except as otherwise described in the Fund’s prospectus.
2. |  | Borrow money, except from banks for temporary or emergency purposes or for repurchase of its shares, and then only in an amount not exceeding one-third of the value of the Fund’s total assets including the amount borrowed. While any such borrowings exceed 5% of the Fund’s total assets, no additional purchases of investment securities will be made. |  | Borrow money, except from banks for temporary or emergency purposes or for repurchase of its shares, and then only in an amount not exceeding one-third of the value of the Fund’s total assets (including the amount borrowed) less the Fund’s liabilities (other than borrowings).

* | The Target Fund has revised certain fundamental policies relating to the purchase of financial futures and options, which have the effect of permitting the Fund to engage in derivative transactions for non-hedging purposes. As a result, the sections of the prospectus referred to here have been superseded. See “Portfolio Composition—Hedging Strategies and Other Uses of Derivatives.”

S-21

(1) | This table presents the fundamental investment restrictions of each Fund as they appear in the respective Fund’s most recent registration statement, as the same may subsequently have been modified with the approval of the holders of a majority of the Fund’s outstanding voting securities. Accordingly, the use of certain defined terms in the table does not necessarily correspond with defined terms used elsewhere in this SAI.

(2) | Section 18(c) of the 1940 Act generally limits a registered closed-end investment company to issuing one class of senior securities representing indebtedness and one class of senior securities representing stock, except that the class of indebtedness or stock may be issued in one or more series, and promissory notes or other evidences of indebtedness issued in consideration of any loan, extension, or renewal thereof, made by a bank or other person and privately arranged, and not intended to be publicly distributed, are not deemed a separate class of senior securities.

(3) | Section 18(a) of the 1940 Act generally prohibits a registered closed-end fund from incurring borrowings if, immediately thereafter, the aggregate amount of its borrowings exceeds 33 1/3% of its total assets. The Funds have obtained exemptive relief to make loans pursuant to the inter-fund lending facility.

(4) | For purposes of this restriction, governments and their political subdivisions are not members of any industry.

(5) | Section 21 of the 1940 Act makes it unlawful for a registered investment company, like the Funds, to lend money or other property if (i) the investment company’s policies set forth in its registration statement do not permit such loan or (ii) the borrower controls or is under common control with the investment company. The Funds have obtained exemptive relief to make loans pursuant to the inter-fund lending facility.

For the purpose of applying the limitation set forth in subparagraph (8) above for each Fund, an issuer shall be deemed the sole issuer of a security 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, such as an industrial corporation or a privately owned or operated hospital, 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 sole 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 the Acquiring 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 (1) 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 (2) 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 shares of the acquired investment company at the time such shares are purchased. As a shareholder in any investment company, each Fund will bear its ratable share of that investment company’s expenses and will remain subject to payment of the 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 the Fund invests in other investment companies. In addition, the securities of other investment companies may be leveraged and therefore will be subject to leverage risk.

In addition to the foregoing fundamental investment policies, each Fund is also subject to the following non-fundamental restrictions and policies that may be changed by the Board of the Fund without prior shareholder notice. 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.

S-22

(2) Invest in securities of other open- or closed-end investment companies (including exchange-traded funds (“ETFs”)) except in compliance with the 1940 Act or any exemptive relief obtained thereunder.

(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 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 the Adviser 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.

The Funds 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 the Funds borrow from a lender, by the lender. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Funds by the 1940 Act. If these restrictions were to apply, it is not anticipated that these covenants or guidelines would impede Nuveen Asset Management from managing the Fund’s portfolio in accordance with the Fund’s investment objectives and policies.

Portfolio Turnover

Portfolio trading may be undertaken to accomplish each Fund’s investment objectives. 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 and/or Sub-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 securities may cause a temporarily low price for such securities, as compared with other securities of like quality and characteristics. Each Fund may also engage to a limited extent in short-term trading consistent with its 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 each Fund will not engage in trading solely to recognize a gain.

Each Fund may engage in portfolio trading when considered appropriate, but short-term trading will not be used as the primary means of achieving a Fund’s investment objectives. Although a Fund cannot accurately predict its annual portfolio turnover rate, it is generally not expected to exceed 100% under normal circumstances. However, there are no limits on a Fund’s rate of portfolio turnover, and investments may be sold without regard to length of time held when, in the Adviser’s and/or Sub-Adviser’s opinion, investment considerations warrant such action. A higher portfolio turnover rate would result in correspondingly greater brokerage commissions and other transactional expenses that are borne by each Fund. Please refer to “Proposal No. 1—A. Synopsis—Material Federal Income Tax Consequences of the Merger” in the Joint Proxy Statement/Prospectus for a discussion of anticipated turnover of the Target Fund in connection with the Merger.

S-23

For the fiscal years ended May 31, 2023 and May 31, 2022, the portfolio turnover rates of the Target Fund were as follows:

Target Fund
2023 |  | 2022
24% |  | 18%

For the fiscal years ended October 31, 2022 and October 31, 2021, the portfolio turnover rates of the Acquiring Fund were as follows:

Acquiring Fund
2022 |  | 2021
36% |  | 12%

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 may result 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 or may result in greater amounts of net capital gain distributions.

S-24

INVESTMENT ADVISER AND SUB-ADVISER

Investment Adviser

Nuveen Fund Advisors is the investment adviser to each Fund and is responsible for overseeing each Fund’s overall investment strategy, including the use of leverage, and its implementation. Nuveen Fund Advisors also is responsible for the ongoing monitoring of any sub-adviser to the Funds, managing each Fund’s business affairs and providing certain clerical, bookkeeping and other administrative services to the Funds. Nuveen Fund Advisors is located at 333 West Wacker Drive, Chicago, Illinois 60606.

Nuveen Fund Advisors, a registered investment adviser, is a subsidiary of Nuveen, the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). TIAA is a life insurance company founded in 1918 by the Carnegie Foundation for the Advancement of Teaching and is the companion organization of College Retirement Equities Fund. As of June 30, 2023, Nuveen managed approximately $1.2 trillion in assets, of which approximately $140.9 billion was managed by Nuveen Fund Advisors.

Unless earlier terminated as described below, each Fund’s Investment Management Agreement with Nuveen Fund Advisors will remain in effect until August 1, 2024. Each Investment 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 the Fund; and (2) a majority of the Board Members who are not interested persons of any party to the Investment Management Agreement, cast in person at a meeting called for the purpose of voting on such approval. Each Investment Management Agreement may be terminated at any time, without penalty, by either the Fund or Nuveen Fund Advisors upon 60 days’ written notice and is automatically terminated in the event of its assignment, as defined in the 1940 Act.

Pursuant to each Investment Management Agreement, each Fund has agreed to pay an annual management fee for the overall advisory and administrative services and general office facilities provided by Nuveen Fund Advisors. Each Fund’s management fee consists of two components—a complex-level fee, based on the aggregate amount of all eligible fund assets of Nuveen-branded closed- and open-end registered investment companies organized in the United States, and a specific fund-level fee, based only on the amount of assets of such Fund. This 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 total dollar amounts paid to Nuveen Fund Advisors by each Fund under each Fund’s Investment Management Agreement for each Fund’s last three fiscal years are as follows:

Target Fund |  | 2023 |  |  | 2022 |  |  | 2021 |
Gross Advisory Fees |  | $ | 1,174,831 |  |  | $ | 1,305,069 |  |  | $ | 1,335,270 |

Sub-Adviser

Nuveen Fund Advisors has selected its wholly owned subsidiary, Nuveen Asset Management, located at 333 West Wacker Drive, Chicago, Illinois 60606, to serve as the sub-adviser to each of the Funds pursuant to a

S-25

Sub-Advisory Agreement between Nuveen Fund Advisors and Nuveen Asset Management. Nuveen Asset Management, a registered investment adviser, oversees day-to-day operations and manages the investment of the Funds’ assets on a discretionary basis, subject to the supervision of Nuveen Fund Advisors. Pursuant to each Sub-Advisory Agreement, Nuveen Asset Management is compensated for the services it provides to the Funds with a portion of the management fee Nuveen Fund Advisors receives from each Fund. Nuveen Fund Advisors and Nuveen Asset Management retain the right to reallocate investment advisory responsibilities and fees between themselves in the future.

For the services provided pursuant to each Fund’s Sub-Advisory Agreement, Nuveen Fund Advisors pays the Sub-Adviser a portfolio management fee, payable monthly, equal to 38.4615%, of the management fee (net of applicable breakpoints, waivers and reimbursements) paid by the Fund to Nuveen Fund Advisors.

The total dollar amounts paid to Nuveen Asset Management by Nuveen Fund Advisors during each Fund’s last three fiscal years are as follows:

Target Fund |  | 2023 |  |  | 2022 |  |  | 2021 |
Sub-Advisory Fees |  | $ | 451,858 |  |  | $ | 501,949 |  |  | $ | 513,565 |
Acquiring Fund |  | 2022 |  |  | 2021 |  |  | 2020 |
Sub-Advisory Fees |  | $ | 14,355,210 |  |  | $ | 15,299,187 |  |  | $ | 14,297,162 |

Portfolio Managers

Unless otherwise indicated, the information below is provided as of the date of this SAI.

Michael Hamilton, is the portfolio manager of the Target Fund. Christopher L. Drahn, CFA is the portfolio manager of the Acquiring Fund. The portfolio management team of the Acquiring Fund will manage the combined fund upon completion of the Merger.

In addition to managing the Funds, the portfolio managers are also primarily responsible for the day-to-day portfolio management of the following accounts, as of May 31, 2023 for Mr. Hamilton and as of October 31, 2022 for Mr. Drahn:

Portfolio Manager |  | Type of Account Managed |  | Number of Accounts |  |  | Assets*
Michael Hamilton |  | Registered Investment Companies |  |  | 8 |  |  | $2.29 billion
|  | Other Pooled Investment Vehicles |  |  | 0 |  |  | $0
|  | Other Accounts |  |  | 0 |  |  | $0
Christopher L. Drahn |  | Registered Investment Companies |  |  | 12 |  |  | $15.65 billion
|  | Other Pooled Investment Vehicles |  |  | 0 |  |  | $0
|  | Other Accounts |  |  | 7 |  |  | $805 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.

Portfolio managers are compensated through a combination of base salary and variable components consisting of (i) a cash bonus; (ii) a long-term performance award; and (iii) participation in a profits interest plan.

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

Cash bonus. A portfolio manager is eligible to receive an annual cash bonus that is based on three variables: risk-adjusted investment performance relative to benchmark generally measured over the most recent one, three and five year periods (unless the portfolio manager’s tenure is shorter), ranking versus Morningstar peer funds generally measured over the most recent one, three and five year periods (unless the portfolio manager’s tenure is shorter), and management and peer reviews.

Long-term performance award. A portfolio manager is eligible to receive a long-term performance award that vests after three years. The amount of the award when granted is based on the same factors used in determining the cash bonus. The value of the award at the completion of the three-year vesting period is adjusted based on the risk-adjusted investment performance of Fund(s) managed by the portfolio manager during the vesting period and the performance of the TIAA organization as a whole.

Profits interest plan. Portfolio managers are eligible to receive profits interests in Nuveen Asset Management and its affiliate, Teachers Advisors, LLC, which vest over time and entitle their holders to a percentage of the firms’ annual profits. Profits interests are allocated to each portfolio manager based on such person’s overall contribution to the firms.

There are generally no differences between the methods used to determine compensation with respect to the Funds and the other accounts shown in the table above.

S-27

Potential Material Conflicts of Interest

Actual or apparent conflicts of interest may arise when a portfolio manager has day-to-day management responsibilities with respect to more than one account. More specifically, portfolio managers who manage multiple accounts are presented with 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 a 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.

Conflicts of interest may also arise when the Sub-Adviser invests one or more of its client accounts in different or multiple parts of the same issuer’s capital structure, including investments in public versus private securities, debt versus equity, or senior versus junior/subordinated debt, or otherwise where there are different or inconsistent rights or benefits. Decisions or actions such as investing, trading, proxy voting, exercising, waiving or amending rights or covenants, workout activity, or serving on a board, committee or other involvement in governance may result in conflicts of interest between clients holding different securities or investments. Generally, individual portfolio managers will seek to act in a manner that they believe serves the best interest of the accounts they manage. In cases where a portfolio manager or team faces a conflict among its client accounts, it will seek to act in a manner that it believes best reflects its overall fiduciary duty, which may result in relative advantages or disadvantages for particular accounts.

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.

Nuveen Asset Management or its affiliates, including TIAA, sponsor an array of financial products for retirement and other investment goals, and provide services worldwide to a diverse customer base. Accordingly, from time to time, a Fund may be restricted from purchasing or selling securities, or from engaging in other investment activities because of regulatory, legal or contractual restrictions that arise due to another client

S-28

account’s investments and/or the internal policies of Nuveen Asset Management, TIAA or its affiliates designed to comply with such restrictions. As a result, there may be periods, for example, when Nuveen Asset Management will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which investment limits have been reached.

The investment activities of Nuveen Asset Management or its affiliates may also limit the investment strategies and rights of the Funds. For example, in certain circumstances where the Funds invest in securities issued by companies that operate in certain regulated industries, in certain emerging or international markets, or are subject to corporate or regulatory ownership definitions, or invest in certain futures and derivative transactions, there may be limits on the aggregate amount invested by Nuveen Asset Management or its affiliates for the Funds and other client accounts that may not be exceeded without the grant of a license or other regulatory or corporate consent. If certain aggregate ownership thresholds are reached or certain transactions undertaken, the ability of Nuveen Asset Management, on behalf of the Funds or other client accounts, to purchase or dispose of investments or exercise rights or undertake business transactions may be restricted by regulation or otherwise impaired. As a result, Nuveen Asset Management, on behalf of the Funds or other client accounts, may limit purchases, sell existing investments, or otherwise restrict or limit the exercise of rights (including voting rights) when Nuveen Asset Management, in its sole discretion, deems it appropriate in light of potential regulatory or other restrictions on ownership or other consequences resulting from reaching investment thresholds.

Beneficial Ownership of Securities. The following table sets forth the dollar range of equity securities beneficially owned by the Funds’ portfolio managers as of May 31, 2023:

Portfolio Manager |  | Dollar Range of Equity Securities Beneficially Owned in the Target Fund |  | Dollar Range of Equity Securities Beneficially Owned in the Acquiring Fund
Michael Hamilton |  | $0 |  | $0
Christopher L. Drahn |  | $0 |  | $0

Code of Ethics

The Funds, Nuveen Fund Advisors, Nuveen Asset Management and other related entities have adopted codes of ethics under Rule 17j-1 under the 1940 Act, which 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. Personnel subject to the Code of Ethics may purchase shares of a Fund and may generally invest in securities in which the Fund may also invest subject to the restrictions set forth in the Code of Ethics. Text-only versions of the Code of Ethics of the Fund, Nuveen Fund Advisors and Nuveen Asset Management can be viewed online or downloaded from the EDGAR Database on the SEC’s internet web site at www.sec.gov.

S-29

PROXY VOTING POLICIES AND PROCEDURES

The Funds invest primarily in municipal securities. On rare occasions a Fund may acquire, directly or through a special purpose vehicle, equity securities of a municipal bond issuer whose bonds the Fund already owns when such bonds 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 municipal bond 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 municipal issuer, Nuveen Asset Management may pursue the Fund’s 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, but nevertheless provides reports to a Fund’s Board on its control activities on a quarterly basis.

In the rare event that a municipal issuer held by a Fund were to issue a proxy, or that the Fund 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 Board or its representative. In the case of a conflict of interest, the proxy would be submitted to the Board to determine how the proxy should be voted. A member of Nuveen Asset Management’s legal department would oversee the administration of the voting and ensure that records were maintained in accordance with Rule 206(4)-6, reports were filed with the SEC on Form N-PX, and the results were provided to the Board and made available to shareholders as required by applicable rules. Nuveen Asset Management’s proxy voting policies and procedures are attached hereto as Appendix C. If applicable, information regarding how each Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available without charge, upon request, by calling (800) 257-8787 or from the Fund’s website at http://www.nuveen.com, and on the SEC’s website at http://www.sec.gov.

S-30

PORTFOLIO TRANSACTIONS AND BROKERAGE

Subject to the supervision of the Board and Nuveen Fund Advisors, 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.

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) the Sub-Adviser 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 information in the table below reflects the aggregate brokerage commission paid by the Target Fund and the Acquiring Fund for the last three fiscal years:

During its most recent fiscal year, neither Fund paid commissions in return for research services or held any securities of its regular broker-dealers.

Under the 1940 Act, each Fund may not purchase portfolio securities from any underwriting syndicate of which Nuveen Securities, LLC is a member except under certain limited conditions set forth in Rule 10f-3. The Rule sets forth requirements relating to, among other things, the terms of a security purchased by the Funds, the amount of securities that may be purchased in any one issue and the assets of the Funds that may be invested in a particular issue. In addition, purchases of securities made pursuant to the terms of the Rule must be approved at least quarterly by each Fund’s Board, including a majority of the independent trustees.

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 Acquiring 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 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. However, there can be no assurance that the Board 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 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 would have to comply with the Securities Exchange Act of 1934 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 at the time it considers such issue, it is the Board’s current 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 from the New York Stock Exchange (the “NYSE”), 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 taxable income to be taxed at the Fund 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, (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 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 approval of the holders of at

S-33

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 Board Members, in which case a majority vote of the requisite holders would be required. See the Joint Proxy Statement/Prospectus under “Additional Information about the Acquiring Fund—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, and the Fund’s preferred shares would no longer be outstanding. In contrast 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 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 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 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 federal income tax consequences that may be relevant to a shareholder that acquires, holds and/or disposes of shares of the Acquiring Fund. Substantially similar consequences would be relevant to a shareholder that acquires, holds and/or disposes of shares of the Target Fund. This discussion addresses only federal income tax consequences to U.S. shareholders who hold their shares as capital assets and does not address all of the 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, conversion transaction or other integrated transaction, holders who are subject to the federal alternative minimum tax (except as discussed below), investors with “applicable financial statements” within the meaning of section 451(b) of the Internal Revenue Code of 1986, as amended (the “Code”), or tax-exempt or tax-advantaged plans, accounts, or entities. In addition, the discussion does not address any state, local or foreign tax consequences. The discussion reflects applicable federal income tax laws of the United States as of the date of this SAI, 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 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.

If a partnership holds shares of the Acquiring Fund, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. The discussion below may not be applicable to an investor who is a partner in a partnership holding Acquiring Fund shares. Such investors should consult their own tax adviser regarding the tax consequences of acquiring, owning and disposing of shares of the Acquiring Fund.

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 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 its shares, subject to the possible application of the federal alternative minimum tax.

To qualify for the favorable federal income tax treatment generally accorded to regulated investment companies, the Acquiring Fund must, among other things, (i) 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; (ii) diversify its holdings so that, at the end of each quarter of each taxable year, (a) 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 (b) 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 (iii) 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.

S-35

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 the Acquiring Fund’s current and accumulated earnings and profits (including distributions from net capital gains 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, provided certain holding period and other requirements under the Code are satisfied.

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 reported by the Acquiring Fund. Exempt-interest dividends will be exempt from 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 federal income tax on its investment company taxable income and net capital gains (the excess of net long-term capital gains over net short-term capital losses), if any, that it distributes to shareholders. The Acquiring Fund may retain for investment its net capital gains. However, if the Acquiring Fund retains any net capital gains or any investment company taxable income, it will be subject to federal income tax at regular corporate rates on the amount retained. If the Acquiring Fund retains any net capital gains, 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 gains, their share of such undistributed amount, and (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 to 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 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 gains 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 (i) 98% of its ordinary taxable income (not taking into account any capital gains or losses) for the calendar year, (ii) 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 (iii) 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 federal income tax. To prevent application of the excise tax, the Acquiring Fund intends to make 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.

S-36

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 net tax-exempt interest, including such income it is required to accrue, to continue to qualify as a regulated investment company and (with respect to taxable 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 it may have to leverage itself by borrowing the cash, to satisfy these distribution requirements.

The Acquiring Fund’s investment in lower rated or unrated debt securities may present issues for the Acquiring Fund if the issuers of these securities default on their obligations because the federal income tax consequences to a holder of such securities are not certain.

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 report 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.

Under section 163(j) of the Code, the amount of business interest that a taxpayer can deduct for any year is generally limited to the taxpayer’s (i) business interest income (which is the amount of interest includible in the gross income of the taxpayer which is properly allocable to a trade or business, but does not include investment income) plus (ii) 30% of adjusted taxable income (but not less than zero) plus (iii) floor plan financing interest. The IRS has issued regulations clarifying that all interest expense and interest income of a regulated investment company is treated as properly allocable to a trade or business for purposes of the limitation on the deductibility of business interest. As a result, this limitation may impact the Acquiring Fund’s ability to use leverage (e.g., borrow money, issue debt securities, etc.). Shareholders of the Acquiring Fund may also be subject to this limitation. The Acquiring Fund is permitted to pass-through its net business interest income (generally the Fund’s business interest income less applicable expenses and deductions) as a “section 163(j) interest dividend.” The amount passed through to shareholders is considered interest income and can be used to determine such shareholder’s business interest deduction under Code section 163(j), if any, subject to holding period requirements and other limitations. The Acquiring Fund may choose not to report such section 163(j) interest dividends.

Distributions to shareholders of net investment income received by the Acquiring Fund from investments that generate taxable income, 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 gains (i.e., the excess of net long-term capital gains over net short-term capital losses), if any, are taxable as long-term capital gains, 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 it is not generally expected to be significant. Taxable distributions are subject to federal income tax whether reinvested in additional shares of the Acquiring Fund or paid in cash.

Distributions, if any, in excess of the Acquiring Fund’s current and accumulated 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). “Qualified dividend

S-37

income” received by noncorporate shareholders is taxed for federal income tax purposes at rates equivalent to long-term capital gains tax rates, which reach a maximum of 20%. Qualified dividend income generally includes dividends from domestic corporations and dividends from non-U.S. corporations that meet certain specified criteria. 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.

Earnings and profits for the current year are generally treated, for federal income tax purposes, as first being used to pay distributions on preferred shares, if any, 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, if any, 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 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 its outstanding preferred shares, if any, 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. However, there can be no assurance 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

S-38

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, exchange or redemption of shares of the Acquiring Fund normally will result in capital gains or losses to shareholders who hold their shares as capital assets. Generally, a shareholder’s gain or loss will be long-term capital gains or losses 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 gains or losses. Current federal income tax law taxes both long-term and short-term capital gains of corporations at the same rates applicable to ordinary income. However, for noncorporate taxpayers, long-term capital gains are currently taxed at a maximum federal income tax rate of 20%, while short-term capital gains are currently taxed at ordinary income rates. 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 (and undistributed net capital gain designated by the Acquiring Fund that is deemed to be 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. The deductibility of capital losses is subject to limitation.

Federal income tax law imposes an alternative minimum tax with respect to 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 receives 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 federal income tax, would be taxable to its shareholders to the extent that their tax liability is determined under the federal alternative minimum tax. Pursuant to its non-fundamental investment policy, the Acquiring Fund does not intend to acquire securities whose income is 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 securities subject to the federal alternative minimum tax. For taxable years beginning after December 31, 2022, federal income tax law also imposes an alternative minimum tax on corporations. Exempt-interest dividends therefore may also affect the corporate alternative minimum tax liability of some corporate shareholders.

Certain noncorporate shareholders are subject to an additional 3.8% tax on some or all of their “net investment income,” which includes items of gross income that are attributable to interest, dividends, original-issue discount and market discount (but not including tax-exempt interest and exempt-interest dividends), as well as net gain from the disposition of certain property. This tax generally applies 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.

S-39

The Acquiring Fund may be required to withhold federal income tax at a rate of 24% from all distributions (including exempt-interest dividends) and redemption proceeds payable to shareholders who fail to provide the Acquiring Fund with their correct taxpayer identification number or to make required certifications, or who have been notified (or the Acquiring Fund has been notified) by the IRS that they are subject to backup withholding. 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 Foreign Account Tax Compliance Act (“FATCA”) generally requires the Acquiring Fund to obtain information sufficient to identify the status of each of its shareholders. If a shareholder fails to provide this information or otherwise fails to comply with FATCA, the Acquiring Fund may be required to withhold under FATCA at a rate of 30% with respect to that shareholder on Acquiring Fund dividends and distributions and redemption proceeds. The Acquiring Fund may disclose the information that it receives from (or concerning) its shareholders to the IRS, non-U.S. taxing authorities or other parties as necessary to comply with FATCA, related intergovernmental agreements or other applicable laws or regulations. Investors are urged to consult their own tax advisers regarding the applicability of FATCA and any other reporting requirements with respect to the investor’s own situation, including investments through an intermediary.

Pursuant to proposed regulations, the Treasury Department has indicated its intent to eliminate the requirements under FATCA of withholding on gross proceeds from the sale, exchange, maturity or other disposition of relevant financial instruments (including redemptions of stock). The Treasury Department has indicated that taxpayers may rely on these proposed regulations pending their finalization.

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.

With respect to the preferred shares of the Acquiring Fund issued in the Merger, the Acquiring Fund will receive an opinion from special tax counsel that the preferred shares will constitute equity of the Acquiring Fund, and the foregoing discussion and the tax opinion received by the Funds regarding certain aspects of the Merger, including that the Merger will qualify as a tax-free reorganization under the Code, relies on the position that the preferred shares will constitute equity of the Acquiring Fund. Accordingly, distributions with respect to the preferred shares (other than distributions in redemption of preferred shares subject to section 302(b) of the Code) will generally constitute dividends to the extent of the Acquiring Fund’s current or accumulated earnings and profits, as calculated for U.S. federal income tax purposes and to the extent allocable to such distribution. Because the treatment of a corporate security as debt or equity is determined on the basis of the facts and circumstances of each case, and no controlling precedent exists for the preferred shares issued in the Merger, there can be no assurance that the IRS will not question special tax counsel’s opinion and the Acquiring Fund’s treatment of the preferred shares as equity. If the IRS were to succeed in such a challenge, holders of preferred shares could be characterized as receiving taxable interest income rather than exempt-interest or other dividends, possibly requiring them to file amended income tax returns and retroactively to recognize additional amounts of ordinary income and to pay additional tax, interest and penalties.

APPENDIX A

RATINGS OF INVESTMENTS

S&P Global Ratings —A brief description of the applicable S&P Global Ratings, a subsidiary of S&P Global Inc. previously McGraw Hill Financial, Inc. (“Standard & Poor’s” or “S&P”), rating symbols and their meanings (as published by S&P) follows:

A S&P Global Ratings issue credit rating is a forward-looking opinion about 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 opinion reflects Standard & Poor’s view of the obligor’s capacity and willingness to meet its financial commitments as they come due, and may assess terms, such as collateral security and subordination, which could affect ultimate payment in the event of default. NR indicates that a rating has not been assigned or is no longer assigned.

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. Medium-term notes are assigned long-term ratings.

LONG-TERM ISSUE CREDIT RATINGS

Issue credit ratings are based in varying degrees, on S&P’s analysis of 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.

Issue ratings are an assessment of default risk, but may incorporate an assessment of relative seniority or ultimate recovery in the event of default. 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.)

|  | AAA |  | An obligation rated ‘AAA’ has the highest rating assigned by S&P Global Ratings. 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 to a 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.

A-1

|  | 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.
|  | CC |  | An obligation rated ‘CC’ is currently highly vulnerable to nonpayment. The ‘CC’ rating is used when a default has not yet occurred, but S&P Global Ratings expects default to be a virtual certainty, regardless of the anticipated time to default.
|  | C |  | An obligation rated ‘C’ is currently highly vulnerable to nonpayment, and the obligation is expected to have lower relative seniority or lower ultimate recovery compared to obligations that are rated higher.
|  | D |  | An obligation rated ‘D’ is in default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D’ rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within five business days in the absence of a stated grace period or within the earlier of the stated grace period or 30 calendar days. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation’s rating is lowered to ‘D’ if it is subject to a distressed debt restructuring.

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.

A-2

SHORT-TERM ISSUE CREDIT RATINGS

|  | A-1 |  | A short-term obligation rated ‘A-1’ is rated in the highest category by S&P Global Ratings. 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 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 vulnerable and has significant speculative characteristics. The obligor currently has the capacity to meet its financial commitments; however, it faces major ongoing uncertainties which could lead to the obligor’s inadequate capacity to meet its financial commitments.
|  | 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 default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D’ rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within any stated grace period. However, any stated grace period longer than five business days will be treated as five business days. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation’s rating is lowered to ‘D’ if it is subject to a distressed debt restructuring.

MUNICIPAL SHORT-TERM NOTE RATINGS DEFINITIONS

A S&P Global Ratings U.S. municipal note rating reflects S&P Global Ratings’ opinion about the liquidity factors and market access risks unique to the notes. Notes due in three years or less will likely receive a note rating. Notes with an original maturity of more than three years will most likely receive a long-term debt rating.

In determining which type of rating, if any, to assign, S&P Global Ratings’ analysis will review the following considerations:

1.  Amortization schedule—the larger the final maturity relative to other maturities, the more likely it will be treated as a note; and

2.  Source of payment—the more dependent the issue is on the market for its refinancing, the more likely it will be treated as a note.

A-3

Note rating symbols are as follows:

|  | SP-1 |  | Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus (+) designation.
|  | SP-2 |  | Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.
|  | SP-3 |  | Speculative capacity to pay principal and interest.
|  | D |  | ‘D’ is assigned upon failure to pay the note when due, completion of a distressed debt restructuring, or the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions.

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:

LONG-TERM OBLIGATION RATINGS

Moody’s long-term ratings are assigned to issuers or obligations with an original maturity of one year or more and reflect both on the likelihood of a default on contractually promised payments and the expected financial loss suffered in the event of default.

|  | Aaa |  | Obligations rated Aaa are judged to be of the highest quality, subject to the lowest level of credit risk.
|  | Aa |  | Obligations rated Aa are judged to be of high quality and are subject to very low credit risk.
|  | A |  | Obligations rated A are judged to be upper-medium grade and are subject to low credit risk.
|  | Baa |  | Obligations rated Baa are judged to be medium-grade and subject to moderate credit risk. They are considered medium grade and as such may possess certain speculative characteristics.
|  | Ba |  | Obligations rated Ba are judged to be speculative and are subject to substantial credit risk.
|  | B |  | Obligations rated B are considered speculative and are subject to high credit risk.
|  | Caa |  | Obligations rated Caa are judged to be speculative, of poor standing, and are subject to very high credit risk.
|  | Ca |  | Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.
|  | C |  | Obligations rated C are the lowest rated and are typically in default, with little prospect for recovery of principal or interest.

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

A-4

SHORT-TERM OBLIGATION RATINGS

Moody’s short-term ratings are assigned to obligations with an original maturity of thirteen months or less and reflect the likelihood of a default on contractually promised payments. Moody’s employs the following designations to indicate the relative repayment ability of rated issuers:

|  | P-1 |  | Issuers (or supporting institutions) rated Prime-1 have a superior ability to repay short-term debt obligations.
|  | P-2 |  | Issuers (or supporting institutions) rated Prime-2 have a strong ability to repay short-term debt obligations.
|  | P-3 |  | Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to repay short-term obligations.
|  | NP |  | Issuers (or supporting institutions) rated Not Prime do not fall within any of the Prime rating categories.

Note: Canadian issuers rated P-1 or P-2 have their short-term ratings enhanced by the senior-most long-term rating of the issuer, its guarantor or support-provider.

U.S. MUNICIPAL SHORT-TERM OBLIGATION RATINGS

|  |  |  | We use the Municipal Investment Grade (MIG) scale for US municipal cash flow notes, bond anticipation notes and certain other short-term obligations, which typically mature in three years or less. Under certain circumstances, we use the MIG scale for bond anticipation notes with maturities of up to five years. MIG 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 |  | This designation denotes strong credit quality. Margins of protection are ample, although not as large as in the preceding group.
|  | MIG 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.

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

Rated entities in a number of sectors, including financial and non-financial corporations, sovereigns, insurance companies and certain sectors within public finance, are generally assigned Issuer Default Ratings (IDRs). IDRs are also assigned to certain entities or enterprises in global infrastructure project finance and public finance. IDRs opine on an entity’s relative vulnerability to default on financial obligations.

The “threshold” default risk addressed by the IDR is generally that of the financial obligations whose non-payment would best reflect the uncured failure of that entity. As such, IDRs also address relative vulnerability to bankruptcy, administrative receivership or similar concepts.

In aggregate, IDRs provide an ordinal ranking of issuers based on the agency’s view of their relative vulnerability to default, rather than a prediction of a specific percentage likelihood of default.

A-5

LONG-TERM CREDIT RATINGS

|  | AAA |  | Highest credit quality. ‘AAA’ ratings denote the lowest expectation of default risk. They are assigned only in case of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.
|  | AA |  | Very high credit quality. ‘AA’ ratings denote expectations of a very low default risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.
|  | A |  | High credit quality. ‘A’ ratings denote expectations of low default risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.
|  | BBB |  | Good credit quality. ‘BBB’ ratings indicate that expectations of default risk are currently low. The capacity for payment of financial commitments is considered adequate, but adverse business or economic conditions are more likely to impair this capacity.
|  | BB |  | Speculative. ‘BB’ ratings indicate an elevated vulnerability to default risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial flexibility exists which supports the servicing of financial commitments.
|  | B |  | Highly speculative. ‘B’ ratings indicate that material default risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, capacity for continued payment is vulnerable to deterioration in the business and economic environment.
|  | CCC |  | Substantial credit risk. Very low margin for safety. Default is a real possibility.
|  | CC |  | Very high levels of credit risk. Default of some kind appears probable.
|  | C |  | Near Default. A Default or default-like process has begun, or the issuer is in standstill, or for a closed funding vehicle, payment capacity is irrevocably impaired. Conditions that are indicative of a ‘C’ category rating for an issuer include:

| a. | the issuer has entered into a grace or cure period following non-payment of a material financial obligation;

| b. | the issuer has entered into a temporary negotiated waiver or standstill agreement following a payment default on a material financial obligation; or

| c. | the formal announcement by the issuer or their agent of a distressed debt exchange

| d. | A closed financing vehicle where payment capacity is irrevocably impaired such that it is not expected to pay interest and/or principal in full during the life of the transaction, but where no payment default is imminent.

|  | RD |  | Restricted default. ‘RD’ ratings indicate an issuer that in Fitch Ratings’ opinion has experienced an uncured payment default on a bond, loan or other material financial obligation but which has not entered into bankruptcy filings, administration, receivership, liquidation or other formal winding-up procedure, and which has not otherwise ceased business. This would include:

| a. | the selective payment default on a specific class or currency of debt;

| b. | the uncured expiry of any applicable grace period, cure period or default forbearance period following a payment default on a bank loan, capital markets security or other material financial obligation;

A-6

| c. | the extension of multiple waivers or forbearance periods upon a payment default on one or more material financial obligations, either in series or in parallel; or

| d. | execution of a distressed debt exchange on one or more material financial obligations.

|  | D |  | Default. ‘D’ ratings indicate an issuer that in Fitch Ratings’ opinion has entered into bankruptcy filings, administration, receivership, liquidation or other formal winding-up procedure, or which has otherwise ceased business. Default ratings are not assigned prospectively to entities or their obligations; within this context, nonpayment on an instrument that contains a deferral feature or grace period will generally not be considered a default until after the expiration of the deferral or grace period, unless a default is otherwise driven by bankruptcy or other similar circumstance, or by a distressed debt exchange.

In all cases, the assignment of a default rating reflects the agency’s opinion as to the most appropriate rating category consistent with the rest of its universe of ratings, and may differ from the definition of default under the terms of an issuer’s financial obligations or local commercial practice.

Note: The modifiers “+” 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 IDR category, or to Long-Term IDR categories below ‘CCC’.

SHORT-TERM OBLIGATION RATINGS

A short-term issuer or obligation rating is based in all cases on the short-term vulnerability to default of the rated entity or security stream and relates to the capacity to meet financial obligations in accordance with the documentation governing the relevant obligation. Short-Term Ratings are assigned to obligations whose initial maturity is viewed as “short term” based on market convention. Typically, this means up to 13 months for corporate, sovereign, and structured obligations, and up to 36 months for obligations in U.S. public finance markets.

|  | F1 |  | Highest short-term credit quality. Indicates the strongest intrinsic capacity for timely payment of financial commitments; may have an added “+” to denote any exceptionally strong credit feature.
|  | F2 |  | Good short-term credit quality. Good intrinsic capacity for timely payment of financial commitments.
|  | F3 |  | Fair short-term credit quality. The intrinsic capacity for timely payment of financial commitments is adequate.
|  | B |  | Speculative short-term credit quality. Minimal capacity for timely payment of financial commitments, plus heightened vulnerability to near-term adverse changes in financial and economic conditions.
|  | C |  | High short-term default risk. Default is a real possibility.
|  | RD |  | Restricted default. Indicates an entity that has defaulted on one or more of its financial commitments, although it continues to meet other financial obligations. Applicable to entity ratings only.
|  | D |  | Default. Indicates a broad-based default event for an entity, or the default of a short-term obligation.

Specific limitations relevant to the issuer credit rating scales include:

| • |  | The ratings do not predict a specific percentage of default likelihood over any given time period.

| • |  | The ratings do not opine on the market value of any issuer’s securities or stock, or the likelihood that this value may change.

A-7

| • |  | The ratings do not opine on the liquidity of the issuer’s securities or stock.

| • |  | The ratings do not opine on the possible loss severity on an obligation should an issuer default, except in the following cases:

| • |  | Ratings assigned to individual obligations of issuers in corporate finance, banks, non-bank financial institutions, insurance and covered bonds.

| • |  | In limited circumstances for U.S. public finance obligations where Chapter 9 of the Bankruptcy Code provides reliably superior prospects for ultimate recovery to local government obligations that benefit from a statutory lien on revenues or during the pendency of a bankruptcy proceeding under the Code if there is sufficient visibility on potential recovery prospects.

| • |  | The ratings do not opine on the suitability of an issuer as counterparty to trade credit.

| • |  | The ratings do not opine on any quality related to an issuer’s business, operational or financial profile other than the agency’s opinion on its relative vulnerability to default. For the avoidance of doubt, not all defaults will be considered a default for rating purposes. Typically, a default relates to a liability payable to an unaffiliated, outside investor.

| • |  | The ratings do not opine on any quality related to a transaction’s profile other than the agency’s opinion on the relative vulnerability to default of an issuer and/or of each rated tranche or security.

| • |  | The ratings do not predict a specific percentage of extraordinary support likelihood over any given period.

| • |  | The ratings do not opine on the suitability of any security for investment or any other purposes.

Ratings assigned by Fitch Ratings articulate an opinion on discrete and specific areas of risk. The above list is not exhaustive, and is provided for the reader’s convenience.

RATING WATCHES AND RATING OUTLOOKS

Rating Watch

Rating Watches indicate that there is a heightened probability of a rating change and the likely direction of such a change. These are designated as “Positive”, indicating a rating could stay at its present level or potentially be upgraded, “Negative”, to indicate that a rating could stay at its present level or potentially be downgraded, or “Evolving”, if ratings may be raised, lowered or affirmed. However, ratings that are not on Rating Watch can be raised or lowered without being placed on Rating Watch first, if circumstances warrant such an action.

A Rating Watch is typically event-driven and, as such, it is generally resolved over a relatively short period. The event driving the Watch may be either anticipated or have already occurred, but in both cases, the exact rating implications remain undetermined. The Watch period is typically used to gather further information and/or subject the information to further analysis. A Rating Watch must be reviewed and a RAC be published every six months after a rating has been placed on Rating Watch, except in the case described below.

Additionally, a Watch may be used where the rating implications are already clear, but where a triggering event (e.g. shareholder or regulatory approval) exists. The Watch will typically extend to cover the period until the triggering event is resolved or its outcome is predictable with a high enough degree of certainty to permit resolution of the Watch. In these cases, where it has previously been communicated within the RAC that the Rating Watch will be resolved upon an event and where there are no material changes to the respective rating up to the event, the Rating Watch may not be reviewed within the six months interval. In any case the affected ratings (and the Rating Watch) will remain subject to an annual review cycle.

A-8

Rating Outlook

Rating Outlooks indicate the direction a rating is likely to move over a one- to two-year period. They reflect financial or other trends that have not yet reached the level that would trigger a rating action, but which may do so if such trends continue. A Positive Rating Outlook indicates an upward trend on the rating scale. Conversely, a Negative Rating Outlook signals a negative trend on the rating scale. Positive or Negative rating Outlooks do not imply that a rating change is inevitable and, similarly, ratings with Stable Outlooks can be raised or lowered without a prior revision to the Outlook, if circumstances warrant such an action. Occasionally, where the fundamental trend has strong, conflicting elements of both positive and negative, the Rating Outlook may be described as Evolving.

Outlooks are currently applied on the long-term scale to issuer ratings in corporate finance (including sovereigns, industrials, utilities, financial institutions and insurance companies) and public finance outside the U.S.; to issue ratings in public finance in the U.S.; to certain issues in project finance; to Insurer Financial Strength Ratings; to issuer and/or issue ratings in a number of National Rating scales; and to the ratings of structured finance transactions. Outlooks are not applied to ratings assigned on the short-term scale and are typically do not apply to ratings in the ‘CCC’, ‘CC’ and ‘C’ categories since the volatility of these ratings is very high and outlooks would be of limited informational value. Defaulted ratings typically do not carry an Outlook.

STANDARD RATING ACTIONS

Assignment (New Rating)* |  | A rating has been assigned to a previously unrated issuer or issue.
Publication (Publish)* |  | Initial public announcement of a rating on the agency’s website, although not necessarily the first rating assigned. This action denotes when a previously private rating is published. In cases where the publication coincides with a rating change, Fitch will only publish the changed rating. The rating history during the time when the rating was private will not be published.
Affirmed* |  | The rating has been reviewed and no change has been deemed necessary. Ratings affirmations may also include an affirmation of, or change to, an Outlook when an outlook is used.
Upgrade* |  | The rating has been raised in the scale.
Downgrade* |  | The rating has been lowered in the scale.
Review-No Action* |  | The rating has been reviewed by a credit rating committee with no change in rating or Outlook. As of the review date, the credit rating committee determined that nothing had sufficiently changed to warrant a new rating action. Such review will be published on the agency’s website, but a RAC will not be issued.
Matured*/Paid-In-Full |  | a.   ‘Matured’—This action is used when an issue has reached the end of its repayment term and rating coverage is discontinued. Denoted as ‘NR’. This indicates that a previously rated issue has been repaid, but other issues of the same program (rated or unrated) may remain outstanding. For the convenience of investors, Fitch may also include issues relating to a rated issuer or transaction that are not and have not been rated on its section of the web page relating to the respective issuer or transaction. b.  ‘Paid-In-Full’—This action indicates that the issue has been paid in full. As the issue no longer exists, it is therefore no longer rated. Denoted as ‘PIF’.

A-9

Pre-refunded* |  | Assigned to long-term US Public Finance issues after Fitch assesses refunding escrow.
Upgrade* |  | The rating has been raised in the scale.
Withdrawn* |  | The rating has been withdrawn and the issue or issuer is no longer rated by Fitch. Withdrawals may occur for one or several of the following reasons: •  Incorrect or insufficient information. •  Bankruptcy of the rated entity, debt restructuring or default. •  Reorganization of rated entity (e.g. merger or acquisition of rated entity or rated entity no longer exists). •  The debt instrument was taken private. •  Withdrawal of a guarantor rating. •  An Expected Rating that is no longer expected to convert to a Final Rating. •  Criteria or policy change. •  Bonds were pre-refunded, repaid early (off schedule), or canceled. This includes cases where the issuer has no debt outstanding and is no longer issuing debt. •  Ratings are no longer considered relevant to the agency’s coverage. •  Commercial reasons. •  Other reasons. When a public rating is withdrawn, Fitch will issue a RAC that details the current rating and Outlook or Watch status (if applicable), a statement that the rating is withdrawn and the reason for the withdrawal. Withdrawals cannot be used to forestall a rating action. Every effort is therefore made to ensure that the rating opinion upon withdrawal reflects an updated view. Where significant elements of uncertainty remain (for example, a rating for an entity subject to a takeover bid) or where information is otherwise insufficient to support a revised opinion, the agency attempts when possible to indicate in the withdrawal disclosure the likely direction and scale of any rating movement had coverage been maintained. Ratings that have been withdrawn will be indicated by the symbol ‘WD’.
Under Critical Observation |  | The rating has been placed “Under Criteria Observation” upon the publication of new or revised criteria that is applicable to the rating, where the new or revised criteria has yet to be applied to the rating and where the criteria could result in a rating change when applied but the impact is not yet known. The status of UCO will be resolved after the application of the new or revised criteria, which must be completed within six months from the publication date of the new or revised criteria. The status of UCO will be resolved after the application of the new or revised criteria, which must be completed within six months from the publication date of the new or revised criteria.

A-10

|  | UCO is only applicable to private and public international credit ratings. It is not applicable to National Ratings, Non-Credit Scale Ratings, Credit Opinions or Rating Assessment Services. It is not applicable to ratings status Paid in Full, Matured, Withdrawn or Not Rated.
Criteria Observation Removed |  | UCO can be addressed and removed by a subsequent rating action such as affirmation, upgrade or downgrade; with these actions, the annual review requirement is also met. Where a rating action has not been taken, a Criteria Observation Removed action may be taken if it has been determined that the rating would not change due to the application of the new criteria. The Criteria Observation Removed action does not satisfy Fitch’s minimum annual credit review requirement.
Recovery Rating Revision |  | Change to an issue’s Recovery Rating.
Rating Modifier Actions |  | Modifiers include Rating Outlooks, and Rating Watches.
Rating Watch Maintained* |  | The issue or issuer has been reviewed and remains on active Rating Watch status.
Rating Watch On* |  | The issue or issuer has been placed on active Rating Watch status.
Rating Watch Revision* |  | Rating Watch status has changed.
Support Floor Rating Revision |  | Applicable only to Support ratings related to Financial Institutions, which are amended only with this action.
Under Review* |  | Applicable to ratings that may undergo a change in scale not related to changes in fundamental credit quality. Final action will be “Revision Rating”
Outlook Revision * |  | Outlook revisions (e.g. to Rating Outlook Stable from Rating Outlook Positive) are used to indicate changes in the ratings trend. In structured finance transactions, the Outlook may be revised independently of a full review of the underlying rating. An Outlook revision may also be used when a series of potential event risks has been identified, none of which individually warrants a Rating Watch but which cumulatively indicate heightened probability of a rating change over the following one to two years. A revision to the Outlook may also be appropriate where a specific event has been identified that could lead to a change in ratings, but where the conditions and implications of that event are largely unclear and subject to high execution risk over a one- to two-year period.

* | A rating action must be recorded for each rating in a required cycle to be considered compliant with Fitch policy concerning aging of ratings. Not all Ratings or Data Actions, or changes in rating modifiers, will meet this requirement. Actions of Reviews that meet this requirement are noted with an “ * ” in the above definitions.

APPENDIX C

NUVEEN PROXY VOTING POLICY

Policy Purpose and Statement

Proxy voting is the primary means by which shareholders may influence a publicly traded company’s governance and operations and thus create the potential for value and positive long-term investment performance. When an SEC registered investment adviser has proxy voting authority, the adviser has a fiduciary duty to vote proxies in the best interests of its clients and must not subrogate its clients’ interests to its own. In their capacity as fiduciaries and investment advisers, Nuveen Asset Management, LLC (“NAM”), Teachers Advisors, LLC (“TAL”) and TIAA-CREF Investment Management, LLC (“TCIM”), (each an “Adviser” and collectively, the “Advisers”), vote proxies for the Portfolio Companies held by their respective clients, including investment companies and other pooled investment vehicles, institutional and retail separate accounts, and other clients as applicable. The Advisers have adopted this Policy, the Nuveen Proxy Voting Guidelines, and the Nuveen Proxy Voting Conflicts of Interest Policy for voting the proxies of the Portfolio Companies they manage. The Advisers leverage the expertise and services of an internal group referred to as the Responsible Investing Team (RI Team) to administer the Advisers’ proxy voting. The RI Team adheres to the Advisers’ Proxy Voting Guidelines which are reasonably designed to ensure that the Advisers vote client securities in the best interests of the Advisers’ clients.

Policy Statement

Proxy voting is a key component of a Portfolio Company’s corporate governance program and is the primary method for exercising shareholder rights and influencing the Portfolio Company’s behavior. Nuveen makes informed voting decisions in compliance with Rule 206(4)-6 (the “Rule”) of the Investment Advisers Act of 1940, as amended (the “Advisers Act”) and applicable laws and regulations, (e.g., the Employee Retirement Income Security Act of 1974, “ERISA”).

Enforcement

As provided in the TIAA Code of Business Conduct, all employees are expected to comply with applicable laws and regulations, as well as the relevant policies, procedures and compliance manuals that apply to Nuveen’s business activities. Violation of this Policy may result in disciplinary action up to and including termination of employment.

Terms and Definitions

Advisory Personnel includes the Adviser’s portfolio managers and/or research analysts.

Proxy Voting Guidelines (the ‘‘Guidelines’’) are a set of pre-determined principles setting forth the manner in which the Advisers intend to vote on specific voting categories, and serve to assist clients, Portfolio Companies, and other interested parties in understanding how the Advisers intend to vote on proxy-related matters. The Guidelines are not exhaustive and do not necessarily dictate how the Advisers will ultimately vote with respect to any proposal or resolution.

Portfolio Company includes any publicly traded company held in an account that is managed by an Adviser.

Policy Requirements

Investment advisers, in accordance with the Rule, are required to (i) adopt and implement written policies and procedures that are reasonably designed to ensure that proxies are voted in the best interest of clients, and address resolution of material conflicts that may arise, (ii) describe their proxy voting procedures to their clients and provide copies on request, and (iii) disclose to clients how they may obtain information on how the Advisers voted their proxies.

C-1

The Nuveen Proxy Voting Committee (the “Committee”), the Advisers, the RI Team and Nuveen Compliance are subject to the respective requirements outlined below under Roles and Responsibilities.

Although it is the general policy to vote all applicable proxies received in a timely fashion with respect to securities selected by an Adviser for current clients, the Adviser may refrain from voting in certain circumstances where such voting would be disadvantageous, materially burdensome or impractical, or otherwise inconsistent with the overall best interest of clients.

Roles and Responsibilities

Nuveen Proxy Voting Committee

The purpose of the Committee is to establish a governance framework to oversee the proxy voting activities of the Advisers in accordance with the Policy. The Committee has delegated responsibility for the implementation and ongoing administration of the Policy to the RI Team, subject to the Committee’s ultimate oversight and responsibility as outlined in the Committee’s Proxy Voting Charter.

Advisers

Advisory Personnel maintain the ultimate decision-making authority with respect to how proxies will be voted, unless otherwise instructed by a client, and may determine to vote contrary to the Guidelines and/or a vote recommendation of the RI Team if such Advisory Personnel determines it is in the best interest of the Adviser’s clients to do so. The rationale for all such contrary vote determinations will be documented and maintained.

When voting proxies for different groups of client accounts, Advisory Personnel may vote proxies held by the respective client accounts differently depending on the facts and circumstances specific to such client accounts. The rationale for all such vote determinations will be documented and maintained.

Advisory Personnel must comply with the Nuveen Proxy Voting Conflicts of Interest Policy with respect to potential material conflicts of interest.

Responsible Investing Team

Performs day-to-day administration of the Advisers’ proxy voting processes.

Seeks to vote proxies in adherence to the Guidelines, which have been constructed in a manner intended to align with the best interests of clients. In applying the Guidelines, the RI Team, on behalf of the Advisers, takes into account several factors, including, but not limited to:

| • |  | Input from Advisory Personnel

| • |  | Third-party research

| • |  | Specific Portfolio Company context, including environmental, social and governance practices, and financial performance.

Delivers copies of the Advisers’ Policy to clients and prospective clients upon request in a timely manner, as appropriate.

Assists with the disclosure of proxy votes as applicable on corporate website and elsewhere as required by applicable regulations.

Prepares reports of proxies voted on behalf of the Advisers’ investment company clients to their Boards or committees thereof, as applicable.

C-2

Performs an annual vote reconciliation for review by the Committee.

Arranges the annual service provider due diligence, including a review of the service provider’s potential conflicts of interests, and presents the results to the Committee.

Facilitates quarterly Committee meetings, including agenda and meeting minute preparation.

Complies with the Nuveen Proxy Voting Conflicts of Interest Policy with respect to potential material conflicts of interest.

Creates and retains certain records in accordance with Nuveen’s Record Management program.

Oversees the proxy voting service provider in making and retaining certain records as required under applicable regulation.

Assesses, in cooperation with Advisory Personnel, whether securities on loan should be recalled in order to vote their proxies.

Nuveen Compliance

Ensures proper disclosure of Advisers’ Policy to clients as required by regulation or otherwise.

Ensures proper disclosure to clients of how they may obtain information on how the Advisers voted their proxies.

Assists the RI Team with arranging the annual service provider due diligence and presenting the results to the Committee.

Monitors for compliance with this Policy and retains records relating to its monitoring activities pursuant to Nuveen’s Records Management program.

Governance

Review and Approval

This Policy will be reviewed at least annually and will be updated sooner if substantive changes are necessary. The Policy Leader, the Committee and the NEFI Compliance Committee are responsible for the review and approval of this Policy.

Implementation

Nuveen has established the Committee to provide centralized management and oversight of the proxy voting process administered by the RI Team for the Advisers in accordance with its Proxy Voting Committee Charter and this Policy.

Exceptions

Any request for a proposed exception or variation to this Policy will be submitted to the Committee for approval and reported to the appropriate governance committee(s), where appropriate.

PART C

OTHER INFORMATION

Item 15. Indemnification

Section 4 of Article XII of the Registrant’s Declaration of Trust, as amended, 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.

C-1

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 (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 joint errors and omissions insurance policies against liability and expenses of claims of wrongful acts arising out of their position with the Registrant and other Nuveen funds, subject to such policies’ coverage limits, exclusions and retention.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the “1933 Act”), may be permitted to trustees, officers and controlling persons of the Registrant pursuant to the Declaration of Trust of the Registrant, 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 1933 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 1933 Act and will be governed by the final adjudication of such issue.
