The Fund currently pays the Advisor a contractual management fee at an annual rate of 0.55% based on an aggregate of (i) the Fund’s average daily Net Assets and (ii) the proceeds of any outstanding debt securities or borrowings used for leverage (together, “average daily Managed Assets”). “Net Assets” means the total assets of the Fund minus the sum of the accrued liabilities. The liquidation preference of any outstanding preferred stock (other than accumulated dividends) is not considered a liability in determining the Fund’s net asset value. The Fund uses leverage in the form of a credit facility, which as of December 19, 2022 amounted to approximately 26.45% of the Fund’s Managed Assets (approximately 35.95% of the Fund’s net assets). “Managed Assets” means the total assets of the Fund minus the sum of the Fund’s accrued liabilities (other than the aggregate indebtedness constituting financial leverage). The Fund’s net assets attributable to common stock are the Fund’s Managed Assets minus the value of the Fund’s assets attributable to indebtedness constituting financial leverage. Thus, when the Fund uses leverage, its net assets attributable to common stock are less than its Managed Assets and its expenses (including the management fee) stated as a percentage of its net assets attributable to common stock are greater than they would be if stated as a percentage of its Managed Assets. This table reflects the fact that you, as a common shareholder, bear the expenses of the Fund’s use of leverage in the form of higher fees as a percentage of the Fund’s net assets attributable to common stock than if the Fund did not use leverage.

(4)

The Fund and the Advisor have entered into a fee waiver agreement (the “Fee Waiver Agreement”), pursuant to which the Advisor has contractually agreed to waive the management fee with respect to any portion of the Fund’s assets attributable to investments in any equity and fixed-income mutual funds and exchange-traded funds (“ETFs”) managed by the Advisor or its affiliates that have a contractual management fee, through June 30, 2024. In addition, pursuant to the Fee Waiver Agreement, the Advisor has contractually agreed to waive its management fees by the amount of investment advisory fees the Fund pays to the Advisor indirectly through its investment in money market funds managed by the Advisor or its affiliates, through June 30, 2024. The Fee Waiver Agreement may be terminated at any time, without the payment of any penalty, only by the Fund (upon the vote of a majority of the Directors who are not “interested persons” (as defined in the Investment Company Act of 1940, as amended (the “Investment Company Act”), of the Fund (the “Independent Directors”)) or a majority of the outstanding voting securities of the Fund), upon 90 days’ written notice by the Fund to the Advisor.

Investment Objectives and Practices [Text Block]

THE FUND’S INVESTMENTS

Investment Objectives and Policies

Please refer to the section of the Fund’s most recent annual report on Form N-CSR entitled “Investment Objectives, Policies and Risks—BlackRock Debt Strategies Fund, Inc. (DSU)”, which is incorporated by reference herein, for a discussion of the Fund’s investment objectives and policies.

Investment Process

In selecting debt instruments and other securities for the Fund, the Advisors will seek to identify issuers and industries that the Advisors believe are likely to experience stable or improving financial conditions. The Advisors’ analysis will include:

•

credit research on the issuers’ financial strength;

•

assessment of the issuers’ ability to meet principal and interest payments;

•

general industry trends;

•

the issuers’ managerial strength;

•

analysis of deal structure and covenants;

•

changing financial conditions;

•

borrowing requirements or debt maturity schedules; and

•

the issuers’ responsiveness to changes in business conditions and interest rates.

The Advisors will consider relative values among issuers based on anticipated cash flow, interest or dividend coverage, asset coverage and earnings prospects. Using these tools, the Advisors will seek to add consistent value and control performance volatility consistent with the Fund’s investment objectives and policies. The Advisors believe this strategy should enhance the Fund’s ability to achieve its investment objectives.

The Advisors’ analysis continues on an ongoing basis for any debt instruments or other securities in which the Fund has invested. Although the Advisors use due care in making such analysis, there can be no assurance that such analysis will reveal factors that may impair the value of the debt instruments.

Portfolio Contents and Techniques

The Fund may invest in the following instruments and use the following investment techniques, subject to any limitations set forth herein. There is no guarantee the Fund will buy all of the types of securities or use all of the investment techniques that are described herein and in the SAI.

Corporate Bonds

Corporate bonds are debt obligations issued by corporations. Corporate bonds may be either secured or unsecured. Collateral used for secured debt includes real property, machinery, equipment, accounts receivable, stocks, bonds or notes. If a bond is unsecured, it is known as a debenture. Bondholders, as creditors, have a prior legal claim over common and preferred stockholders as to both income and assets of the corporation for the principal and interest due them and may have a prior claim over other creditors if liens or mortgages are involved. Interest on corporate bonds may be fixed or floating, or the bonds may be zero coupons. Interest on corporate bonds is typically paid semi-annually and is fully taxable to the bondholder. Corporate bonds contain elements of both interest rate risk and credit risk. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates and may also be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the marketplace. Corporate bonds usually yield more than government or agency bonds due to the presence of credit risk.

High Yield Securities (“Junk Bonds”)

The Fund may invest in securities rated, at the time of investment, below investment grade quality such as those rated Ba or below by Moody’s Investors Service, Inc. (“Moody’s”) or BB or below by S&P Global Ratings (“S&P”) or Fitch Ratings (“Fitch”), or securities comparably rated by other rating agencies or in unrated securities determined by the Advisors to be of comparable quality. Such securities, sometimes referred to as “high yield” or “junk” bonds, are predominantly speculative with respect to the capacity to pay interest and repay principal in accordance with the terms of the security and generally involve greater price volatility than securities in higher rating categories. Often the protection of interest and principal payments with respect to such securities may be very moderate and issuers of such securities face major ongoing uncertainties or exposure to adverse business, financial or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments.

Lower grade securities, though high yielding, are characterized by high risk. They may be subject to certain risks with respect to the issuing entity and to greater market fluctuations than certain lower yielding, higher rated securities. The secondary market for lower grade securities may be less liquid than that of higher rated securities. Adverse conditions could make it difficult at times for the Fund to sell certain securities or could result in lower prices than those used in calculating the Fund’s NAV.

The prices of fixed income securities generally are inversely related to interest rate changes; however, the price volatility caused by fluctuating interest rates of securities also is inversely related to the coupons of such securities. Accordingly, below investment grade securities may be relatively less sensitive to interest rate changes than higher quality securities of comparable maturity because of their higher coupon. The investor receives this higher coupon in return for bearing greater credit risk. The higher credit risk associated with below investment grade securities potentially can have a greater effect on the value of such securities than may be the case with higher quality issues of comparable maturity.

Lower grade securities may be particularly susceptible to economic downturns. It is likely that an economic recession could severely disrupt the market for such securities and may have an adverse impact on the value of such securities. In addition, it is likely that any such economic downturn could adversely affect the ability of the issuers of such securities to repay principal and pay interest thereon and increase the incidence of default for such securities.

The ratings of Moody’s, S&P, Fitch and other rating agencies represent their opinions as to the quality of the obligations which they undertake to rate. Ratings are relative and subjective and, although ratings may be useful in evaluating the safety of interest and principal payments, they do not evaluate the market value risk of such obligations. Although these ratings may be an initial criterion for selection of portfolio investments, the Advisors also will independently evaluate these securities and the ability of the issuers of such securities to pay interest and principal. To the extent that the Fund invests in lower grade securities that have not been rated by a rating agency, the Fund’s ability to achieve its investment objectives will be more dependent on the Advisors’ credit analysis than would be the case when the Fund invests in rated securities.

Distressed and Defaulted Securities

The Fund may invest in securities of financially distressed and bankrupt issuers, including debt obligations that are in covenant or payment default. Such investments generally trade significantly below par and are considered speculative. The repayment of defaulted obligations is subject to significant uncertainties. Defaulted obligations might be repaid only after lengthy workout or bankruptcy proceedings, during which the issuer might not make any interest or other payments. Typically such workout or bankruptcy proceedings result in only partial recovery of cash payments or an exchange of the defaulted obligation for other debt or equity securities of the issuer or its affiliates, which may in turn be illiquid or speculative.

Senior Loans

The senior loans in which the Fund invests may consist of direct obligations of a borrower undertaken to finance the growth of the borrower’s business, internally or externally, or to finance a capital restructuring. Senior loans may also include debtor in possession financings pursuant to Chapter 11 of the U.S. Bankruptcy Code and obligations of a borrower issued in connection with a restructuring pursuant to Chapter 11 of the U.S. Bankruptcy Code. A significant portion of such senior loans are highly leveraged loans such as leveraged

buy-out

loans, leveraged recapitalization loans and other types of acquisition loans. Such senior loans may be structured to include both term loans, which are generally fully funded at the time of the Fund’s investment, and revolving credit facilities or delayed draw term loans, which would require the Fund to make additional investments in the senior loans as required under the terms of the credit facility. Such senior loans may also include receivables purchase facilities, which are similar to revolving credit facilities secured by a borrower’s receivables, senior loans designed to provide “bridge” financing to a borrower pending the sale of identified assets or the arrangement of longer-term loans or the issuance and sale of debt obligations or senior loans of borrowers that have obtained bridge loans from other parties. Senior loans generally are issued in the form of senior syndicated loans, but the Fund also may invest from time to time in privately placed notes, credit linked notes, structured notes or other instruments with credit and pricing terms which are, in the opinion of the Advisors, consistent with investments in senior loan obligations.

The senior loans in which the Fund invests typically have stated maturities ranging from five to nine years, though such stated maturities could vary from this range and the Fund is not subject to any restrictions with respect to the maturity of senior loans held in its portfolio. As a result, as short-term interest rates increase, interest payable to the Fund from its investments in senior loans should increase, and as short-term interest rates decrease, interest payable to the Fund from its investments in senior loans should decrease. Because of prepayments, the Advisors expect the average life of the senior loans in which the Fund invests to be shorter than the stated maturity.

The senior loans in which the Fund invests generally hold a senior position in the capital structure of the borrower. Such loans may include loans that hold the most senior position, loans that hold an equal ranking with other senior debt, or loans that are, in the judgment of the Advisors, in the category of senior debt. A senior position in the borrower’s capital structure generally gives the holder of the senior loan a claim on some or all of the borrower’s assets that is senior to that of subordinated debt, preferred stock and common stock in the event the borrower defaults or becomes bankrupt. The senior loans in which the Fund invests may be wholly or partially secured by collateral, or may be unsecured. In the event of a default, the ability of an investor to have access to any collateral may be limited by bankruptcy and other insolvency laws. The value of the collateral also may decline subsequent to the Fund’s investment in the senior loan. Under certain circumstances, the collateral may be released with the consent of the Agent Bank and

Co-Lenders

(each as defined below), or pursuant to the terms of the underlying credit agreement with the borrower. There is no assurance that the liquidation of the collateral will satisfy the borrower’s obligation in the event of nonpayment of scheduled interest or principal, or that the collateral could be readily liquidated. As a result, the Fund might not receive payments to which it is entitled and thereby may experience a decline in the value of the investment, and possibly, its NAV.

In the case of highly leveraged senior loans, a borrower is often required to pledge collateral that may include (i) working capital assets, such as accounts receivable and inventory, (ii) tangible fixed assets, such as real property, buildings and equipment, (iii) intangible assets, such as trademarks, copyrights and patent rights and/or (iv) security interests in securities of subsidiaries or affiliates. Collateral also may include guarantees or other credit support by subsidiaries or affiliates. In some cases the only collateral for the senior loan is the stock of the borrower and/or its subsidiaries and affiliates. To the extent a senior loan is secured by stock of the borrower

and/or its subsidiaries and affiliates, such stock may lose all of its value in the event of a bankruptcy or insolvency of the borrower. In the case of senior loans to privately held companies, the companies’ owners may provide additional credit support in the form of guarantees and/or pledges of other securities that they own.

In the case of project finance loans, the borrower is generally a special purpose entity that pledges undeveloped land and other

non-income

producing assets as collateral and obtains construction completion guaranties from third parties, such as the project sponsor. Project finance credit facilities typically provide for payment of interest from escrowed funds during a scheduled construction period, and for the pledge of current and fixed assets after the project is constructed and becomes operational. During the construction period, however, the lenders bear the risk that the project will not be constructed in a timely manner, or will exhaust project funds prior to completion. In such an event, the lenders may need to take legal action to enforce the completion guaranties, or may need to lend more money to the project on less favorable financing terms, or may need to liquidate the undeveloped project assets. There can be no assurance in any of such cases that the lenders will recover all of their invested capital.

The rate of interest payable on senior floating rate loans is established as the sum of a base lending rate plus a specified margin. These base lending rates generally are the prime rate (“Prime Rate”) of a designated U.S. bank, London Interbank Offered Rate (“LIBOR”), the Certificate of Deposit (“CD”) rate or another base lending rate used by commercial lenders. The interest rate on Prime Rate-based senior loans floats daily as the Prime Rate changes, while the interest rate on LIBOR-based and

CD-based

senior loans is reset periodically, typically every one, two, three or six months. Certain of the senior floating rate loans in which the Fund invests permit the borrower to select an interest rate reset period of up to one year. A portion of the Fund’s portfolio may be invested in senior loans with interest rates that are fixed for the term of the loan. Investment in senior loans with longer interest rate reset periods or fixed interest rates may increase fluctuations in the Fund’s NAV, and potentially the market price of the Fund’s shares of common stock, as a result of changes in interest rates.

The Fund may receive and/or pay certain fees in connection with its lending activities. These fees are in addition to interest payments received and may include facility fees, commitment fees, amendment and waiver fees, commissions and prepayment fees. In certain circumstances, the Fund may receive a prepayment fee on the prepayment of a senior loan by a borrower. In connection with the acquisition of senior loans or other debt securities, the Fund also may acquire warrants and other debt and equity securities of the borrower or issuer or its affiliates. The Fund may also acquire other debt and equity securities of the borrower or issuer in connection with an amendment, waiver, conversion or exchange of a senior loan or in connection with a bankruptcy or workout of the borrower or issuer.

In making an investment in a senior loan, the Advisors will consider factors deemed by it to be appropriate to the analysis of the borrower and the senior loan. The Advisors performs their own independent credit analysis of the borrower in addition to utilizing information prepared and supplied by the Agent Bank,

Co-Lender

or Participant (each defined below) from whom the Fund purchases its interest in a senior loan. Such factors include, but are not limited to, the legal/protective features associated with the securities (such as their position in the borrower’s capital structure and any security through collateral), financial ratios of the borrower such as

pre-tax

interest coverage, leverage ratios, and the ratios of cash flows to total debts and the ratio of tangible assets to debt. In its analysis of these factors, the Advisors also will be influenced by the nature of the industry in which the borrower is engaged, the nature of the borrower’s assets and the Advisors’ assessments of the general quality of the borrower. The Advisors’ analysis continues on an ongoing basis for any senior loans in which the Fund has invested. Although the Advisors use due care in making such analysis, there can be no assurance that such analysis will disclose factors that may impair the value of the senior loan.

Senior loans made in connection with highly leveraged transactions are subject to greater credit risks than other senior loans in which each Fund may invest. These credit risks include a greater possibility of default or bankruptcy of the borrower and the assertion that the pledging of collateral to secure the loan constituted a fraudulent conveyance or preferential transfer which can be nullified or subordinated to the rights of other creditors of the borrower under applicable law.

Many senior loans in which the Fund invests may not be rated by a rating agency, are not registered with the SEC, or any state securities commission, and are not listed on any national securities exchange. Borrowers may have outstanding debt obligations that are rated below investment grade by a rating agency. Many of the senior loans in

which the Fund invests will have been assigned below investment grade ratings by independent rating agencies. In the event senior loans are not rated, they are likely to be the equivalent of below investment grade quality. The Advisors do not view ratings as the determinative factor in its investment decisions and relies more upon its credit analysis abilities than upon ratings.

Except with respect to high yield securities which are the subject of bankruptcy proceedings or otherwise in default as to the repayment of principal and/or payment of interest at the time of acquisition by the Fund or are rated in the lowest rating categories (Ca or lower by Moody’s, CC or lower by S&P or CC or lower by Fitch) or, if unrated, are considered by the Advisors to be of comparable quality (“Distressed Securities”), the Fund has no policy with regard to minimum ratings for senior loans in which it may invest. The Fund may purchase and retain in its portfolio senior loans where the borrower has experienced, or may be perceived to be likely to experience, credit problems, including involvement in or recent emergence from bankruptcy reorganization proceedings or other forms of debt restructuring. Such investments may provide opportunities for enhanced income as well as capital appreciation, although they also will be subject to greater risk of loss. At times, in connection with the restructuring of a senior loan either outside of bankruptcy court or in the context of bankruptcy court proceedings, the Fund may determine or be required to accept equity securities or junior fixed-income securities in exchange for all or a portion of a senior loan.

The secondary market for trading of senior loans continues to develop and mature. One of the effects of a more active and liquid secondary market, however, is that a senior loan may trade at a premium or discount to the principal amount, or par value, of the loan. There are many factors that influence the market value of a senior loan, including technical factors relating to the operation of the loan market, supply and demand conditions, market perceptions about the credit quality or financial condition of the borrower or more general concerns about the industry in which the borrower operates. The Fund participates in this secondary market for senior loans, purchasing and selling loans that may trade at a premium or discount to the par value of the loan. However, no active trading market may exist for some senior loans and some loans may be subject to restrictions on resale. A secondary market may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods, which may impair the ability to realize full value and thus cause a material decline in the Fund’s NAV. In addition, the Fund may not be able to readily dispose of its senior loans at prices that approximate those at which the Fund could sell such loans 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. During periods of limited supply and liquidity of senior loans, the Fund’s yield may be lower.

When interest rates decline, the value of a fund invested in fixed rate obligations can be expected to rise. Conversely, when interest rates rise, the value of a fund invested in fixed rate obligations can be expected to decline. Although changes in prevailing interest rates can be expected to cause some fluctuations in the value of floating rate senior loans (due to the fact that floating rates on senior loans only reset periodically), the value of floating rate senior loans is substantially less sensitive to changes in market interest rates than fixed rate instruments. As a result, to the extent the Fund invests in floating rate senior loans, the Fund’s portfolio may be less volatile and less sensitive to changes in market interest rates than if the Fund invested in fixed rate obligations. Similarly, a sudden and significant increase in market interest rates may cause a decline in the value of these investments and in the Fund’s NAV. Other factors (including, but not limited to, rating downgrades, credit deterioration, a large downward movement in stock prices, a disparity in supply and demand of certain securities or market conditions that reduce liquidity) can reduce the value of senior loans and other debt obligations, impairing the Fund’s NAV.

A borrower must comply with various restrictive covenants contained in any credit agreement between the borrower and the lending syndicate. Such covenants, in addition to requiring the scheduled payment of interest and principal, may include restrictions on dividend payments and other distributions to stockholders, provisions requiring the borrower to maintain specific financial ratios or relationships, limits on total debt and restrictions on the borrower’s ability to pledge its assets. In addition, the loan agreement may contain a covenant requiring the borrower to prepay the senior loan with any excess cash flow. Excess cash flow generally includes net cash flow after scheduled debt service payments and permitted capital expenditures, among other things, as well as the proceeds from asset dispositions or sales of securities. A breach of a covenant (after giving effect to any cure period) which is not waived by the Agent Bank and the lending syndicate normally is an event of default (i.e., the Agent Bank has the right to call the outstanding senior loan).

Senior loans usually require, in addition to scheduled payments of interest and principal, the prepayment of the senior loan from excess cash flow, as discussed above, and typically permit the borrower to prepay at its election. The degree to which borrowers prepay senior loans, whether as a contractual requirement or at their election, may be affected by general business conditions, the financial condition of the borrower and competitive conditions among lenders, among other factors. Accordingly, prepayments cannot be predicted with accuracy. Upon a prepayment, the Fund may receive both a prepayment fee from the prepaying borrower and a facility fee on the purchase of a new senior loan with the proceeds from the prepayment of the former. Such fees may mitigate any adverse impact on the yield on the Fund’s portfolio which may arise as a result of prepayments and the reinvestment of such proceeds in senior loans bearing lower interest rates.

A senior loan in which the Fund may invest typically is originated, negotiated and structured by a syndicate of lenders

(“Co-Lenders”)

consisting of commercial banks, thrift institutions, insurance companies, finance companies, investment banking firms, securities brokerage houses or other financial institutions or institutional investors, one or more of which administers the loan on behalf of the syndicate (the “Agent Bank”).

Co-Lenders

may sell senior loans to third parties (“Participants”). The Fund invests in a senior loan either by participating in the primary distribution as a

Co-Lender

at the time the loan is originated or by buying an assignment or participation interest in the senior loan in the secondary market from a

Co-Lender

or a Participant.

The Fund may invest in a senior loan at origination as a

Co-Lender

or by acquiring an assignment or participation interest in the secondary market from a

Co-Lender

or Participant. If the Fund purchases an assignment, the Fund typically accepts all of the rights of the assigning lender in a senior loan, including the right to receive payments of principal and interest and other amounts directly from the borrower and to enforce its rights as a lender directly against the borrower and assumes all of the obligations of the assigning lender, including any obligations to make future advances to the borrower. As a result, therefore, the Fund has the status of a

Co-Lender.

In some cases, the rights and obligations acquired by a purchaser of an assignment may differ from, and may be more limited than, the rights and obligations of the assigning lender. The Fund also may purchase a participation in a portion of the rights of a

Co-Lender

or Participant in a senior loan by means of a participation agreement. A participation is similar to an assignment in that the

Co-Lender

or Participant transfers to the Fund all or a portion of an interest in a senior loan. Unlike an assignment, however, a participation does not establish any direct relationship between the Fund and the borrower. In such a case, the Fund is required to rely on the

Co-Lender

or Participant that sold the participation not only for the enforcement of the Fund’s rights against the borrower but also for the receipt and processing of payments due to the Fund under the senior loans.

Because it may be necessary to assert through a

Co-Lender

or Participant such rights as may exist against the borrower, in the event the borrower fails to pay principal and interest when due, the Fund may be subject to delays, expenses and risks that are greater than those that would be involved if the Fund could enforce its rights directly against the borrower. Moreover, under the terms of a participation, the Fund may be regarded as a creditor of the

Co-Lender

or Participant that sold the participation (rather than of the borrower), so that the Fund may also be subject to the risk that the

Co-Lender

or Participant may become insolvent. Similar risks may arise with respect to the Agent Bank, as described below. Further, in the event of the bankruptcy or insolvency of the borrower, the obligation of the borrower to repay the senior loan may be subject to certain defenses that can be asserted by such borrower as a result of improper conduct by the Agent Bank,

Co-Lender

or Participant.

In a typical senior loan, the Agent Bank administers the terms of the credit agreement and is responsible for the collection of principal and interest and fee payments from the borrower and the apportionment of these payments to the credit of all lenders which are parties to the credit agreement. The Fund generally relies on the Agent Bank (or the

Co-Lender

or Participant that sold the Fund a participation interest) to collect its portion of the payments on the senior loan. Furthermore, the Fund generally relies on the Agent Bank to use appropriate creditor remedies against the borrower. Typically, under credit agreements, the Agent Bank is given broad discretion in enforcing the credit agreement, and is obligated to use only the same care it would use in the management of its own property. The borrower compensates the Agent Bank for these services. Such compensation may include special fees paid on structuring and funding the senior loan and other fees paid on a continuing basis.

In the event that an Agent Bank becomes insolvent, or has a receiver, conservator, or similar official appointed for it by the appropriate bank regulatory authority or becomes a debtor in a bankruptcy proceeding, assets held by the Agent Bank under the credit agreement should remain available to holders of senior loans.

If, however, assets held by the Agent Bank for the benefit of the Fund were determined by an appropriate regulatory authority or court to be subject to the claims of the Agent Bank’s general or secured creditors, the Fund might incur certain costs and delays in realizing payment on a senior loan or suffer a loss of principal and/or interest. In situations involving a

Co-Lender

or Participant that sold the Fund a participation interest, similar risks may arise, as described above.

The Fund may have certain obligations pursuant to a credit agreement, which may include the obligation to make future advances to the borrower in connection with revolving credit facilities in certain circumstances. These commitments may have the effect of requiring the Fund to increase its investment in a borrower at a time it might not be desirable to do so (including at a time when the borrower’s financial condition makes it unlikely that such amounts will be repaid). The Fund currently intends to reserve against such contingent obligations by designating sufficient investments in liquid assets on its books and records.

The Fund may obtain exposure to senior loans through the use of derivative instruments, which have recently become increasingly available. The Advisors may utilize these instruments and similar instruments that may be available in the future. The Fund may invest in a derivative instrument known as a Select Aggregate Market Index (“SAMI”), which provides investors with exposure to a reference basket of senior loans. SAMIs are structured as floating rate instruments. SAMIs consist of a basket of credit default swaps whose underlying reference securities are senior secured loans. While investing in SAMIs will increase the universe of floating rate fixed-income securities to which the Fund is exposed, such investments entail risks that are not typically associated with investments in other floating rate fixed-income securities. The liquidity of the market for SAMIs will be subject to liquidity in the secured loan and credit derivatives markets. Investment in SAMIs involves many of the risks associated with investments in derivative instruments discussed generally herein.

Second Lien Loans

The Fund may invest in second lien or other subordinated or unsecured floating rate and fixed rate loans or debt. Second lien loans have the same characteristics as senior loans except that such loans are second in lien property rather than first. Second lien loans typically have adjustable floating rate interest payments. Accordingly, the risks associated with second lien loans are higher than the risk of loans with first priority over the collateral. In the event of default on a second lien loan, the first priority lien holder has first claim to the underlying collateral of the loan. It is possible that no collateral value would remain for the second priority lien holder, which may result in a loss of investment to the Fund.

Mezzanine Loans

The Fund may invest in mezzanine loans. Structurally, mezzanine loans usually rank subordinate in priority of payment to senior debt, such as senior bank debt, and are often unsecured. However, mezzanine loans rank senior to common and preferred equity in a borrower’s capital structure. Mezzanine debt is often used in leveraged buyout and real estate finance transactions. Typically, mezzanine loans have elements of both debt and equity instruments, offering the fixed returns in the form of interest payments associated with senior debt, while providing lenders an opportunity to participate in the capital appreciation of a borrower, if any, through an equity interest. This equity interest typically takes the form of warrants. Due to their higher risk profile and often less restrictive covenants as compared to senior loans, mezzanine loans generally earn a higher return than senior secured loans. The warrants associated with mezzanine loans are typically detachable, which allows lenders to receive repayment of their principal on an agreed amortization schedule while retaining their equity interest in the borrower. Mezzanine loans also may include a “put” feature, which permits the holder to sell its equity interest back to the borrower at a price determined through an agreed-upon formula. Mezzanine investments may be issued with or without registration rights. Similar to other high yield securities, maturities of mezzanine investments are typically seven to ten years, but the expected average life is significantly shorter at three to five years; however, maturities and expected average lives could vary from these ranges and the Fund is not subject to any restrictions with respect to the maturities or expected average lives of mezzanine loans held in its portfolio. Mezzanine investments are usually unsecured and subordinate to other obligations of the issuer.

Debtor-In-Possession

Financings

The Fund may invest in

“debtor-in-possession”

or “DIP” financings newly issued in connection with “special situation” restructuring and refinancing transactions. DIP financings are loans to a

debtor-in-possession

in a proceeding under the U.S. Bankruptcy Code that has been approved by the bankruptcy court. These financings allow the entity to continue its business operations while reorganizing under Chapter 11 of the U.S. Bankruptcy Code. DIP financings are typically fully secured by a lien on the debtor’s otherwise unencumbered assets or secured by a junior lien on the debtor’s encumbered assets (so long as the loan is fully secured based on the most recent current valuation or appraisal report of the debtor). DIP financings are often required to close with certainty and in a rapid manner in order to satisfy existing creditors and to enable the issuer to emerge from bankruptcy or to avoid a bankruptcy proceeding.

Mortgage Related Securities

MBS

. Mortgage-backed securities (“MBS”) include structured debt obligations collateralized by pools of commercial (“CMBS”) or residential (“RMBS”) mortgages. Pools of mortgage loans and mortgage-backed loans, such as mezzanine loans, are assembled as securities for sale to investors by various governmental, government-related and private organizations. MBS include complex instruments such as collateralized mortgage obligations (“CMOs”), stripped MBS, mortgage pass-through securities and interests in real estate mortgage investment conduits (“REMICs”). The MBS in which the Fund may invest include those with fixed, floating or variable interest rates, those with interest rates that change based on multiples of changes in a specified reference interest rate or index of interest rates and those with interest rates that change inversely to changes in interest rates, as well as those that do not bear interest. The Fund may invest in RMBS and CMBS issued by governmental entities and private issuers, including subordinated MBS and residual interests. The Fund may invest in

sub-prime

mortgages or MBS that are backed by

sub-prime

mortgages.

B-Note,

if any, then by the “first loss” subordinated security holder (generally, the

“B-Piece”

buyer) and then by the holder of a higher rated security. The Fund may invest in any class of security included in a securitization. In the event of default and the exhaustion of any equity support, reserve fund, letter of credit, mezzanine loans or

B-Notes,

and any classes of securities junior to those in which the Fund invests, the Fund will not be able to recover all of its investment in the MBS it purchases. MBS in which the Fund invests may not contain reserve funds, letters of credit, mezzanine loans and/or junior classes of securities. The prices of lower credit quality securities are generally less sensitive to interest rate changes than more highly rated investments, but more sensitive to adverse economic downturns or individual issuer developments.

Mortgage Pass-Through Securities.

Mortgage pass-through securities differ from other forms of fixed-income securities, which normally provide for periodic payment of interest in fixed amounts with principal payments at maturity or specified call dates. Instead, these securities provide a monthly payment which consists of both interest and principal payments. In effect, these payments are a “pass through” of the monthly payments made by the individual borrowers on their residential or commercial mortgage loans, net of any fees paid to the issuer or guarantor of such securities. Additional payments are caused by repayments of principal resulting from the sale of the underlying property, refinancing or foreclosure, net of fees or costs that may be incurred. Some mortgage related securities (such as securities issued by the Government National Mortgage Association (“GNMA”)) are described as “modified pass-through.” These securities entitle the holder to receive all interest and principal payments owed on the mortgage pool, net of certain fees, at the scheduled payment dates regardless of whether or not the mortgagor actually makes the payment.

RMBS.

RMBS are securities the payments on which depend primarily on the cash flow from residential mortgage loans made to borrowers that are secured, on a first priority basis or second priority basis, subject to permitted liens, easements and other encumbrances, by residential real estate

(one-

to four-family properties), the proceeds of which are used to purchase real estate and purchase or construct dwellings thereon or to refinance indebtedness previously used for such purposes.

Non-agency

residential mortgage loans are obligations of the borrowers thereunder only and are not typically insured or guaranteed by any other person or entity. The ability of a

borrower to repay a loan secured by residential property is dependent upon the income or assets of the borrower. A number of factors, including a general economic downturn, acts of God, terrorism, social unrest and civil disturbances, may impair a borrower’s ability to repay its loans.

Agency RMBS.

The principal U.S. Governmental guarantor of mortgage related securities is GNMA, which is a wholly owned U.S. Government corporation within the Department of Housing and Urban Development. GNMA is authorized to guarantee, with the full faith and credit of the U.S. Government, the timely payment of principal and interest on securities issued by institutions approved by GNMA (such as savings and loan institutions, commercial banks and mortgage bankers) and backed by pools of mortgages insured by the Federal Housing Administration (“FHA”) or guaranteed by the Department of Veterans Affairs (“VA”). MBS issued by GNMA include GNMA Mortgage Pass-Through Certificates (also known as “Ginnie Maes”) which are guaranteed as to the timely payment of principal and interest by GNMA and such guarantees are backed by the full faith and credit of the United States. GNMA certificates also are supported by the authority of GNMA to borrow funds from the U.S. Treasury to make payments under its guarantee.

Government-related guarantors (i.e., not backed by the full faith and credit of the U.S. Government) include the Federal National Mortgage Association (“FNMA”) and the Federal Home Loan Mortgage Corporation (“FHLMC”). FNMA is a government-sponsored corporation the common stock of which is owned entirely by private stockholders. FNMA purchases conventional (i.e., not insured or guaranteed by any government agency) residential mortgages from a list of approved seller/servicers which include state and federally chartered savings and loan associations, mutual savings banks, commercial banks and credit unions and mortgage bankers. Pass-through securities issued by FNMA (also known as “Fannie Maes”) are guaranteed as to timely payment of principal and interest by FNMA, but are not backed by the full faith and credit of the U.S. Government. FHLMC was created by Congress in 1970 for the purpose of increasing the availability of mortgage credit for residential housing. It is a government-sponsored corporation that issues FHLMC Guaranteed Mortgage Pass-Through Certificates (also known as “Freddie Macs” or “PCs”), which are pass-through securities, each representing an undivided interest in a pool of residential mortgages. FHLMC guarantees the timely payment of interest and ultimate collection of principal, but PCs are not backed by the full faith and credit of the U.S. Government.

In 2008, the Federal Housing Finance Agency (“FHFA”) placed FNMA and FHLMC into conservatorship. FNMA and FHLMC are continuing to operate as going concerns while in conservatorship and each remains liable for all of its obligations, including its guaranty obligations, associated with its MBS.

As the conservator, FHFA succeeded to all rights, titles, powers and privileges of FNMA and FHLMC and of any stockholder, officer or director of FNMA and FHLMC with respect to FNMA and FHLMC and the assets of FNMA and FHLMC. In connection with the conservatorship, the U.S. Treasury entered into a Senior Preferred Stock Purchase Agreement with each of FNMA and FHLMC pursuant to which the U.S. Treasury would purchase up to an aggregate of $100 billion of each of FNMA and FHLMC to maintain a positive net worth in each enterprise. This agreement contains various covenants that severely limit each enterprise’s operations. In exchange for entering into these agreements, the U.S. Treasury received $1 billion of each enterprise’s senior preferred stock and warrants to purchase 79.9% of each enterprise’s common stock. In February 2009, the U.S. Treasury doubled the size of its commitment to each enterprise under the Senior Preferred Stock Program to $200 billion. The U.S. Treasury’s obligations under the Senior Preferred Stock Program are for an indefinite period of time for a maximum amount of $200 billion per enterprise. In December 2009, the U.S. Treasury announced further amendments to the Senior Preferred Stock Purchase Agreements and extended additional financial support to certain governmentally supported entities, including the Federal Home Loan Banks (“FHLBs”), FNMA and FHLMC. It is difficult, if not impossible, to predict the future political, regulatory or economic changes that could impact FNMA, FHLMC and the FHLBs, and the values of their related securities or obligations. There is no assurance that the obligations of such entities will be satisfied in full, or that such obligations will not decrease in value or default. In August 2012, the U.S. Treasury announced a third amendment to the Amended and Restated Senior Preferred Stock Purchase Agreements that replaced the fixed-dividend rate of 10% with a variable dividend structure, in which FNMA and FHLMC would transfer to the U.S. Treasury on a quarterly basis all net profits during that quarter. Each enterprise would also be required to reduce its investment portfolios by 15% rather than the previously established 10% annual reduction. In December 2017, FHFA and the U.S. Treasury agreed to reinstate a $3 billion capital reserve amount for each of FNMA and FHLMC. The agreements changed the terms of the Senior Preferred Stock certificate to permit each of FNMA and FHLMC to retain a $3 billion capital reserve each quarter so that each of FNMA and FHLMC will only pay a dividend to the U.S. Treasury if the net worth at the end of a quarter is more than $3 billion.

Under the Federal Housing Finance Regulatory Reform Act of 2008 (the “Reform Act”), which was included as part of the Housing and Economic Recovery Act of 2008, FHFA, as conservator or receiver, has the power to repudiate any contract entered into by FNMA or FHLMC prior to FHFA’s appointment as conservator or receiver, as applicable, if FHFA determines, in its sole discretion, that performance of the contract is burdensome and that repudiation of the contract promotes the orderly administration of FNMA’s or FHLMC’s affairs. The Reform Act requires FHFA to exercise its right to repudiate any contract within a reasonable period of time after its appointment as conservator or receiver. FHFA, in its capacity as conservator, has indicated that it has no intention to repudiate the guaranty obligations of FNMA or FHLMC because FHFA views repudiation as incompatible with the goals of the conservatorship. However, in the event that FHFA, as conservator or if it is later appointed as receiver for FNMA or FHLMC, were to repudiate any such guaranty obligation, the conservatorship or receivership estate, as applicable, would be liable for actual direct compensatory damages in accordance with the provisions of the Reform Act. Any such liability could be satisfied only to the extent of FNMA’s or FHLMC’s assets available therefor. In the event of repudiation, the payments of interest to holders of FNMA or FHLMC MBS would be reduced if payments on the mortgage loans represented in the mortgage loan groups related to such MBS are not made by the borrowers or advanced by the servicer. Any actual direct compensatory damages for repudiating these guaranty obligations may not be sufficient to offset any shortfalls experienced by such MBS holders. Further, in its capacity as conservator or receiver, FHFA has the right to transfer or sell any asset or liability of FNMA or FHLMC without any approval, assignment or consent. Although FHFA has stated that it has no present intention to do so, if FHFA, as conservator or receiver, were to transfer any such guaranty obligation to another party, holders of FNMA or FHLMC MBS would have to rely on that party for satisfaction of the guaranty obligation and would be exposed to the credit risk of that party. In addition, certain rights provided to holders of MBS issued by FNMA and FHLMC under the operative documents related to such securities may not be enforced against FHFA, or enforcement of such rights may be delayed, during the conservatorship or any future receivership. The operative documents for FNMA and FHLMC MBS may provide (or with respect to securities issued prior to the date of the appointment of the conservator may have provided) that upon the occurrence of an event of default on the part of FNMA or FHLMC, in its capacity as guarantor, which includes the appointment of a conservator or receiver, holders of such MBS have the right to replace FNMA or FHLMC as trustee if the requisite percentage of MBS holders consent. The Reform Act prevents MBS holders from enforcing such rights if the event of default arises solely because a conservator or receiver has been appointed. A 2011 report to Congress from the Treasury Department and the Department of Housing and Urban Development set forth a plan to reform America’s housing finance market, which would reduce the role of and eventually eliminate FNMA and FHLMC. Notably, the plan did not propose similar significant changes to GNMA, which guarantees payments on mortgage related securities backed by federally insured or guaranteed loans. The report also identified three proposals for Congress and the administration to consider for the long-term structure of the housing finance markets after the elimination of FNMA and FHLMC, including implementing: (i) a privatized system of housing finance that limits government insurance to very limited groups of creditworthy

low-

and moderate-income borrowers; (ii) a privatized system with a government backstop mechanism that would allow the government to insure a larger share of the housing finance market during a future housing crisis; and (iii) a privatized system where the government would offer reinsurance to holders of certain highly rated mortgage related securities insured by private insurers and would pay out under the reinsurance arrangements only if the private mortgage insurers were insolvent.

Non-Agency

RMBS.

Non-agency

RMBS are issued by commercial banks, savings and loan institutions, mortgage bankers, private mortgage insurance companies and other

non-governmental

issuers. Timely payment of principal and interest on RMBS backed by pools created by

non-governmental

issuers often is supported partially by various forms of insurance or guarantees, including individual loan, title, pool and hazard insurance. The insurance and guarantees are issued by government entities, private insurers and the mortgage poolers. There can be no assurance that the private insurers or mortgage poolers can meet their obligations under the policies, so that if the issuers default on their obligations, the holders of the security could sustain a loss. No insurance or guarantee covers the Fund or the price of the Fund’s common shares. RMBS issued by

non-governmental

issuers generally offer a higher rate of interest than government agency and government-related securities because there are no direct or indirect government guarantees of payment.

CMBS.

CMBS generally are multi-class debt or pass-through certificates secured or backed by mortgage loans on commercial properties. CMBS generally are structured to provide protection to the senior class investors against potential losses on the underlying mortgage loans. This protection generally is provided by having the holders of subordinated classes of securities (“Subordinated CMBS”) take the first loss if there are defaults on the underlying commercial mortgage loans. Other protection, which may benefit all of the classes or particular classes, may include issuer guarantees, reserve funds, additional Subordinated CMBS, cross-collateralization and over-collateralization.

The Fund may invest in Subordinated CMBS, which are subordinated in some manner as to the payment of principal and/or interest to the holders of more senior CMBS arising out of the same pool of mortgages and which are often referred to as

“B-Pieces.”

The holders of Subordinated CMBS typically are compensated with a higher stated yield than are the holders of more senior CMBS. On the other hand, Subordinated CMBS typically subject the holder to greater risk than senior CMBS and tend to be rated in a lower rating category (frequently a substantially lower rating category) than the senior CMBS issued in respect of the same mortgage pool. Subordinated CMBS generally are likely to be more sensitive to changes in prepayment and interest rates and the market for such securities may be less liquid than is the case for traditional income securities and senior CMBS.

CMOs

. A CMO is a multi-class bond backed by a pool of mortgage pass-through certificates or mortgage loans. CMOs may be collateralized by (i) GNMA, FNMA or FHLMC pass-through certificates, (ii) unsecuritized mortgage loans insured by the FHA or guaranteed by the VA, (iii) unsecuritized conventional mortgages, (iv) other MBS or (v) any combination thereof. Each class of a CMO, often referred to as a “tranche,” is issued at a specific coupon rate and has a stated maturity or final distribution date. Principal prepayments on collateral underlying a CMO may cause it to be retired substantially earlier than its stated maturity or final distribution date. The principal and interest on the underlying mortgages may be allocated among the several classes of a series of a CMO in many ways. One or more tranches of a CMO may have coupon rates which reset periodically at a specified increment over an index, such as LIBOR (or sometimes more than one index). These floating rate CMOs typically are issued with lifetime caps on the coupon rate thereon. CMO residuals represent the interest in any excess cash flow remaining after making the payments of interest and principal on the tranches issued by the CMO and the payment of administrative expenses and management fees.

The Fund may invest in inverse floating rate CMOs. Inverse floating rate CMOs constitute a tranche of a CMO with a coupon rate that moves in the reverse direction relative to an applicable index such as LIBOR. Accordingly, the coupon rate thereon will increase as interest rates decrease. Inverse floating rate CMOs are typically more volatile than fixed or floating rate tranches of CMOs. Many inverse floating rate CMOs have coupons that move inversely to a multiple of an index. The effect of the coupon varying inversely to a multiple of an applicable index creates a leverage factor. Inverse floating rate debt instruments (“inverse floaters”) based on multiples of a stated index are designed to be highly sensitive to changes in interest rates and can subject the holders thereof to extreme reductions of yield and loss of principal. The market for inverse floating rate CMOs with highly leveraged characteristics at times may be very thin. The Fund’s ability to dispose of its positions in such securities will depend on the degree of liquidity in the markets for such securities. It is impossible to predict the amount of trading interest that may exist in such securities, and therefore the future degree of liquidity.

Stripped MBS.

Stripped MBS are created by segregating the cash flows from underlying mortgage loans or mortgage securities to create two or more new securities, each receiving a specified percentage of the underlying security’s principal or interest payments. Mortgage securities may be partially stripped so that each investor class receives some interest and some principal. When securities are completely stripped, however, all of the interest is distributed to holders of one type of security, known as an interest-only security (or “IO”), and all of the principal is distributed to holders of another type of security, known as a principal-only security (or “PO”). Strips can be created in a pass-through structure or as tranches of a CMO. The yields to maturity on IOs and POs are very sensitive to the rate of principal payments (including prepayments) on the related underlying mortgage assets. If the underlying mortgage assets experience greater than anticipated prepayments of principal, the Fund may not fully recoup its initial investment in IOs. Conversely, if the underlying mortgage assets experience less than anticipated prepayments of principal, the yield on POs could be materially and adversely affected.

Adjustable Rate Mortgage Securities

. Adjustable rate mortgages (“ARMs”) have interest rates that reset at periodic intervals. Acquiring ARMs permits the Fund to participate in increases in prevailing current interest rates

through periodic adjustments in the coupons of mortgages underlying the pool on which ARMs are based. Such ARMs generally have higher current yield and lower price fluctuations than is the case with more traditional fixed-income securities of comparable rating and maturity. In addition, when prepayments of principal are made on the underlying mortgages during periods of rising interest rates, the Fund may potentially reinvest the proceeds of such prepayments at rates higher than those at which they were previously invested. Mortgages underlying most ARMs, however, have limits on the allowable annual or lifetime increases that can be made in the interest rate that the mortgagor pays. Therefore, if current interest rates rise above such limits over the period of the limitation, the Fund, when holding an ARM, does not benefit from further increases in interest rates. Moreover, when interest rates are in excess of the coupon rates (i.e., the rates being paid by mortgagors) of the mortgages, ARMs behave more like fixed-income securities and less like adjustable-rate securities and are subject to the risks associated with fixed-income securities. In addition, during periods of rising interest rates, increases in the coupon rate of ARMs generally lag current market interest rates slightly, thereby creating the potential for capital depreciation on such securities.

Sub-Prime

Mortgages

Sub-prime

mortgages are mortgages rated below “A” by S&P, Moody’s, or Fitch. Historically,

sub-prime

mortgage loans have been made to borrowers with blemished (or

non-existent)

credit records, and the borrower is charged a higher interest rate to compensate for the greater risk of delinquency and the higher costs of loan servicing and collection.

Sub-prime

mortgages are subject to both state and federal anti-predatory lending statutes that carry potential liability to secondary market purchasers such as the Fund.

Sub-prime

mortgages have certain characteristics and associated risks similar to below investment grade securities, including a higher degree of credit risk, and certain characteristics and associated risks similar to MBS, including prepayment risk.

Mortgage Related ABS

. Asset-backed securities (“ABS”) are bonds backed by pools of loans or other receivables. ABS are created from many types of assets, including in some cases mortgage related asset classes, such as home equity loan ABS. Home equity loan ABS are subject to many of the same risks as RMBS, including interest rate risk and prepayment risk.

Mortgage REITs

. A real estate investment trust (“REIT”) is a corporation, or a business trust that would otherwise be taxed as a corporation, that meets the definitional requirements applicable to REITs under the Internal Revenue Code of 1986, as amended (the “Code”). The Code permits a qualifying REIT to deduct dividends paid, thereby generally eliminating corporate level U.S. federal income tax and effectively making the REIT a pass-through vehicle for U.S. federal income tax purposes. To meet the definitional requirements of the Code, a REIT must, among other things, invest substantially all of its assets in interests in real estate (including mortgages and other REITs) or cash and government securities, derive most of its income from rents from real property or interest on loans secured by mortgages on real property, and distribute to shareholders annually substantially all of its otherwise taxable income. REITs possess certain risks which differ from an investment in common stocks. REITs are financial vehicles that pool investor’s capital to purchase or finance real estate. REITs may concentrate their investments in specific geographic areas or in specific property types (i.e., hotels, shopping malls, residential complexes and office buildings). Distributions received by the Fund from REITs may consist of dividends, capital gains and/or return of capital. As REITs generally pay a higher rate of dividends (on a

pre-tax

basis) than operating companies, to the extent application of the Fund’s investment strategy results in the Fund investing in REIT shares, the percentage of the Fund’s dividend income received from REIT shares will likely exceed the percentage of the Fund’s portfolio which is comprised of REIT shares. There are three general categories of REITs: equity REITs, mortgage REITs and hybrid REITs. Equity REITs invest primarily in direct fee ownership or leasehold ownership of real property; they derive most of their income from rents. Mortgage REITs invest mostly in mortgages on real estate, which may secure construction, development or long-term loans, and the main source of their income is mortgage interest payments. Hybrid REITs hold both ownership and mortgage interests in real estate. The value of securities issued by REITs is affected by tax and regulatory requirements and by perceptions of management skill. They also are subject to heavy cash flow dependency and the possibility of failing to qualify for REIT status under the Code or to maintain exemption from the Investment Company Act.

Mortgage Related Derivative Instruments

. The Fund may invest in MBS credit default swaps. MBS credit default swaps include swaps the reference obligation for which is an MBS or related index, such as the CMBX Index (a tradeable index referencing a basket of CMBS), the TRX Index (a tradeable index referencing total return swaps based on CMBS) or the ABX Index (a tradeable index referencing a basket of

sub-prime

MBS). The Fund

may engage in other derivative transactions related to MBS, including purchasing and selling exchange-listed and

over-the-counter

put and call options, futures and forwards on mortgages and MBS. The Fund may invest in newly developed mortgage related derivatives that may hereafter become available.

Net Interest Margin (NIM) Securities

. The Fund may invest in net interest margin (“NIM”) securities. These securities are derivative interest-only mortgage securities structured off home equity loan transactions. NIM securities receive any “excess” interest computed after paying coupon costs, servicing costs and fees and any credit losses associated with the underlying pool of home equity loans. Like traditional stripped mortgage-backed securities, the yield to maturity on a NIM security is sensitive not only to changes in prevailing interest rates but also to the rate of principal payments (including prepayments) on the underlying home equity loans. NIM securities are highly sensitive to credit losses on the underlying collateral and the timing in which those losses are taken.

Tiered Index Bonds

. Tiered index bonds are relatively new forms of mortgage-related securities. The interest rate on a tiered index bond is tied to a specified index or market rate. So long as this index or market rate is below a predetermined “strike” rate, the interest rate on the tiered index bond remains fixed. If, however, the specified index or market rate rises above the “strike” rate, the interest rate of the tiered index bond will decrease. Thus, under these circumstances, the interest rate on a tiered index bond, like an inverse floater, will move in the opposite direction of prevailing interest rates, with the result that the price of the tiered index bond may be considerably more volatile than that of a fixed-rate bond.

TBA Commitments

. The Fund may enter into “to be announced” or “TBA” commitments. TBA commitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities, for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate and mortgage terms.

Other Mortgage Related Securities

. Other mortgage related securities include securities other than those described above that directly or indirectly represent a participation in, or are secured by and payable from, mortgage loans on real property. Other mortgage related securities may be equity or debt securities issued by agencies or instrumentalities of the U.S. Government or by private originators of, or investors in, mortgage loans, including savings and loan associations, homebuilders, mortgage banks, commercial banks, investment banks, partnerships, trusts and special purpose entities of the foregoing.

Asset-Backed Securities

ABS are a form of structured debt obligation. The securitization techniques used for ABS are similar to those used for MBS. ABS are bonds backed by pools of loans or other receivables. The collateral for these securities may include home equity loans, automobile and credit card receivables, boat loans, computer leases, airplane leases, mobile home loans, recreational vehicle loans and hospital account receivables. The Fund may invest in these and other types of ABS that may be developed in the future. ABS present certain risks that are not presented by mortgage related securities. Primarily, these securities may provide the Fund with a less effective security interest in the related collateral than do mortgage related securities. Therefore, there is the possibility that recoveries on the underlying collateral may not, in some cases, be available to support payments on these securities.

Collateralized Debt Obligations

The Fund may invest in collateralized debt obligations (“CDOs”), which include collateralized bond obligations (“CBOs”), collateralized loan obligations (“CLOs”) and other similarly structured securities. CDOs are types of asset-backed securities. A CBO is ordinarily issued by a trust or other special purpose entity (“SPE”) and is typically backed by a diversified pool of fixed-income securities (which may include high risk, below investment grade securities) held by such issuer. A CLO is ordinarily issued by a trust or other SPE and is typically collateralized by a pool of loans, which may include, among others, domestic and

non-U.S.

senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans, held by such issuer. Although certain CDOs may benefit from credit enhancement in the form of a senior-subordinate structure, over-collateralization or bond insurance, such enhancement may not always be present, and may fail to protect the Fund against the risk of loss on default of the collateral. Certain CDO

issuers may use derivatives contracts to create “synthetic” exposure to assets rather than holding such assets directly, which entails the risks of derivative instruments described elsewhere in this Prospectus. CDOs may charge management fees and administrative expenses, which are in addition to those of the Fund.

For both CBOs and CLOs, the cash flows from the SPE are split into two or more portions, called tranches, varying in risk and yield. The riskiest portion is the “equity” tranche, which bears the first loss from defaults from the bonds or loans in the SPE and serves to protect the other, more senior tranches from default (though such protection is not complete). Since it is partially protected from defaults, a senior tranche from a CBO or CLO typically has higher ratings and lower yields than its underlying securities, and may be rated investment grade. Despite the protection from the equity tranche, CBO or CLO tranches can experience substantial losses due to actual defaults, downgrades of the underlying collateral by rating agencies, forced liquidation of the collateral pool due to a failure of coverage tests, increased sensitivity to defaults due to collateral default and disappearance of protecting tranches, market anticipation of defaults as well as investor aversion to CBO or CLO securities as a class. Interest on certain tranches of a CDO may be paid in kind or deferred and capitalized (paid in the form of obligations of the same type rather than cash), which involves continued exposure to default risk with respect to such payments.

Delayed Funding Loans and Revolving Credit Facilities

The Fund may enter into, or acquire participations in, delayed funding loans and revolving credit facilities, in which a bank or other lender agrees to make loans up to a maximum amount upon demand by the borrower during a specified term. These commitments may have the effect of requiring the Fund to increase its investment in a company at a time when it might not be desirable to do so (including at a time when the company’s financial condition makes it unlikely that such amounts will be repaid). Delayed funding loans and revolving credit facilities are subject to credit, interest rate and liquidity risk and the risks of being a lender.

Zero-Coupon Bonds,

Step-Ups

and

Payment-In-Kind

Securities

Zero-coupon bonds pay interest only at maturity rather than at intervals during the life of the security. Like

zero-coupon

bonds, “step up” bonds pay no interest initially but eventually begin to pay a coupon rate prior to maturity, which rate may increase at stated intervals during the life of the security.

Payment-in-kind

securities (“PIKs”) are debt obligations that pay “interest” in the form of other debt obligations, instead of in cash. Each of these instruments is normally issued and traded at a deep discount from face value. Zero-coupon bonds,

step-ups

and PIKs allow an issuer to avoid or delay the need to generate cash to meet current interest payments and, as a result, may involve greater credit risk than bonds that pay interest currently or in cash. The Fund would be required to distribute the income on these instruments as it accrues, even though the Fund will not receive 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, to make income distributions to its shareholders.

U.S. Government Debt Securities

The Fund may invest in debt securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities, including U.S. Treasury obligations, which differ in their interest rates, maturities and times of issuance. Such obligations include U.S. Treasury bills (maturity of one year or less), U.S. Treasury notes (maturity of one to ten years) and U.S. Treasury bonds (generally maturities of greater than ten years), including the principal components or the interest components issued by the U.S. Government under the separate trading of registered interest and principal securities program (i.e., “STRIPS”), all of which are backed by the full faith and credit of the United States.

Municipal Securities

The Fund may invest in municipal securities, which include debt obligations issued to obtain funds for various public purposes, including the construction of a wide range of public facilities, refunding of outstanding obligations and obtaining funds for general operating expenses and loans to other public institutions and facilities. In addition, certain types of private activity bonds (“PABs”) (or industrial development bonds, under

pre-1986

law) are issued by or on behalf of public authorities to finance various privately owned or operated facilities, including

among other things, airports, public ports, mass commuting facilities, multi-family housing projects, as well as facilities for water supply, gas, electricity, sewage or solid waste disposal and other specialized facilities. Other types of PABs, the proceeds of which are used for the construction, equipment or improvement of privately operated industrial or commercial facilities, may constitute municipal securities. The interest on municipal securities may bear a fixed rate or be payable at a variable or floating rate. The two principal classifications of municipal securities are “general obligation” bonds and “revenue” bonds, which latter category includes PABs. Municipal securities typically are issued to finance public projects, such as roads or public buildings, to pay general operating expenses or to refinance outstanding debt. Municipal securities may also be issued for private activities, such as housing, medical and educational facility construction, or for privately owned industrial development and pollution control projects. General obligation bonds are backed by the full faith and credit, or taxing authority, of the issuer and may be repaid from any revenue source. Revenue bonds may be repaid only from the revenues of a specific facility or source. 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. Obligations are included within the term municipal securities if the interest paid thereon is excluded from gross income for U.S. federal income tax purposes in the opinion of bond counsel to the issuer.

General Obligation Bonds

. General obligation bonds are secured by the issuer’s pledge of its faith, credit and taxing power for the payment of principal and interest. The taxing power of any governmental entity may be limited, however, by provisions of its state constitution or laws, and an entity’s creditworthiness will depend on many factors, including potential erosion of its tax base due to population declines, natural disasters, declines in the state’s industrial base or inability to attract new industries, economic limits on the ability to tax without eroding the tax base, state legislative proposals or voter initiatives to limit ad valorem real property taxes and the extent to which the entity relies on federal or state aid, access to capital markets or other factors beyond the state’s or entity’s control. Accordingly, the capacity of the issuer of a general obligation bond as to the timely payment of interest and the repayment of principal when due is affected by the issuer’s maintenance of its tax base.

Revenue Bonds

. Revenue bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue sources such as payments from the user of the facility being financed. Accordingly, the timely payment of interest and the repayment of principal in accordance with the terms of the revenue or special obligation bond is a function of the economic viability of such facility or such revenue source. 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. Such 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. Increases in interest rates payable on senior obligations may make it more difficult for issuers to meet payment obligations on subordinated bonds.

Moral Obligation Bonds

. The Fund may also invest in “moral obligation” bonds, which are normally issued by special purpose public authorities. If an issuer of moral obligation bonds is unable to meet its obligations, the repayment of such bonds becomes a moral commitment but not a legal obligation of the state or municipality in question.

Municipal Lease Obligations

. The Fund may invest in participations in lease obligations or installment purchase contract obligations (hereinafter collectively called “Municipal Lease Obligations”) of municipal authorities or entities. Although a Municipal Lease Obligation does not constitute a general obligation of the municipality for which the municipality’s taxing power is pledged, a Municipal Lease Obligation is ordinarily backed by the municipality’s covenant to budget for, appropriate and make the payments due under the Municipal Lease Obligation. However, certain Municipal Lease Obligations contain

“non-appropriation”

clauses, which provide that the municipality has no obligation to make lease or installment purchase payments in future years

unless money is appropriated for such purpose on a yearly basis. In the case of a

“non-appropriation”

lease, the Fund’s ability to recover under the lease in the event of

non-appropriation

or default will be limited solely to the repossession of the leased property, without recourse to the general credit of the lessee, and the disposition or

re-leasing

of the property might prove difficult.

Certificates of Participation

. A certificate of participation represents an undivided interest in an unmanaged pool of municipal leases, installment purchase agreements or other instruments. The certificates are typically issued by a municipal agency, a trust or other entity that has received an assignment of the payments to be made by the state or political subdivision under such leases or installment purchase agreements. Such certificates provide the 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.

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, formerly referred to as industrial development bonds, are issued by or on behalf of public authorities to obtain funds to provide privately operated housing facilities, airports, 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. Such bonds are secured primarily by revenues derived from loan repayments or lease payments due from the entity, which may or may not be guaranteed by a parent company or otherwise secured. Private activity bonds generally are not secured by a pledge of the taxing power of the issuer of such bonds. Therefore, an investor should be aware that repayment of such bonds generally depends on the revenues of a private entity and be aware of the risks that such an investment may entail. Continued ability of an entity to generate sufficient revenues for the payment of principal and interest on such bonds will be affected by many factors, including the size of the entity, capital structure, demand for its products or services, competition, general economic conditions, government regulation and the entity’s dependence on revenues for the operation of the particular facility being financed.

Special Taxing Districts

. Special taxing districts are organized to plan and finance infrastructure developments to induce residential, commercial and industrial growth and redevelopment. Bonds issued pursuant to financing methods such as tax increment finance, tax assessment, special services district and Mello-Roos bonds (a type of municipal security established by the Mello-Roos Community Facilities District Act of 1982), are generally payable solely from taxes or other revenues attributable to the specific projects financed by the bonds without recourse to the credit or taxing power of related or overlapping municipalities. They often are exposed to real estate development-related risks and can have more taxpayer concentration risk than general

tax-supported

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

VRDOs

. Variable rate demand obligations (“VRDOs”) are

tax-exempt

obligations that contain a floating or variable interest rate adjustment formula and right of demand on the part of the holder thereof to receive payment

of the unpaid principal balance plus accrued interest upon a short notice period not to exceed seven days. There is, however, the possibility that because of default or insolvency the demand feature of VRDOs may not be honored. The interest rates are adjustable at intervals (ranging from daily to up to one year) to some prevailing market rate for similar investments, such adjustment formula being calculated to maintain the market value of the VRDOs, at approximately the par value of the VRDOs on the adjustment date. The adjustments typically are based upon SIFMA or some other appropriate interest rate adjustment index. The Fund may invest in all types of

tax-exempt

instruments currently outstanding or to be issued in the future. VRDOs that contain an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest on a notice period exceeding seven days may be deemed to be illiquid securities.

Taxable Municipal Securities

. The Fund may invest in taxable municipal securities, which include obligations issued pursuant to the American Recovery and Reinvestment Act (“ARRA”) or other legislation providing for the issuance of taxable municipal debt on which the issuer receives federal support (any bonds so issued are considered “Build America Bonds”). If the Fund invests in Build America Bonds, it expects to invest in direct pay Build America Bonds and “principal only” strips of tax credit Build America Bonds. Provisions of the ARRA relevant to the issuance of Build America Bonds expired on December 31, 2010 and, as such, issuance has ceased.

Preferred Securities

The Fund may invest in preferred securities. There are two basic types of preferred securities. The first type, sometimes referred to as traditional preferred securities, consists of preferred stock issued by an entity taxable as a corporation. The second type, sometimes referred to as trust preferred securities, are usually issued by a trust or limited partnership and represent preferred interests in deeply subordinated debt instruments issued by the corporation for whose benefit the trust or partnership was established.

Traditional Preferred Securities

. Traditional preferred securities generally pay fixed or adjustable rate dividends to investors and generally have a “preference” over common stock in the payment of dividends and the liquidation of a company’s assets. This means that a company must pay dividends on preferred stock before paying any dividends on its common stock. In order to be payable, distributions on such preferred securities must be declared by the issuer’s board of directors. Income payments on typical preferred securities currently outstanding are cumulative, causing dividends and distributions to accumulate even if not declared by the board of directors or otherwise made payable. In such a case all accumulated dividends must be paid before any dividend on the common stock can be paid. However, some traditional preferred stocks are

non-cumulative,

in which case dividends do not accumulate and need not ever be paid. A portion of the portfolio may include investments in

non-cumulative

preferred securities, whereby the issuer does not have an obligation to make up any arrearages to its shareholders. Should an issuer of a

non-cumulative

preferred stock held by the Fund determine not to pay dividends on such stock, the amount of dividends the Fund pays may be adversely affected. There is no assurance that dividends or distributions on the traditional preferred securities in which the Fund invests will be declared or otherwise made payable.

Preferred stockholders usually have no right to vote for corporate directors or on other matters. Shares of traditional preferred securities have a liquidation value that generally equals the original purchase price at the date of issuance. The market value of preferred securities may be affected by favorable and unfavorable changes impacting companies in the utilities and financial services sectors, which are prominent issuers of preferred securities, and by actual and anticipated changes in tax laws, such as changes in corporate income tax rates or the “Dividends Received Deduction.” Because the claim on an issuer’s earnings represented by traditional preferred securities may become onerous when interest rates fall below the rate payable on such securities, the issuer may redeem the securities. Thus, in declining interest rate environments in particular, the Fund’s holdings, if any, of higher rate-paying fixed rate preferred securities may be reduced and the Fund may be unable to acquire securities of comparable credit quality paying comparable rates with the redemption proceeds.

Trust Preferred Securities

. Trust preferred securities are a comparatively new asset class. Trust preferred securities are typically issued by corporations, generally in the form of interest-bearing notes with preferred security characteristics, or by an affiliated business trust of a corporation, generally in the form of beneficial interests in subordinated debentures or similarly structured securities. The trust preferred securities market consists of both fixed and adjustable coupon rate securities that are either perpetual in nature or have stated maturity dates.

Trust preferred securities are typically junior and fully subordinated liabilities of an issuer or the beneficiary of a guarantee that is junior and fully subordinated to the other liabilities of the guarantor. In addition, trust preferred securities typically permit an issuer to defer the payment of income for eighteen months or more without triggering an event of default. Generally, the deferral period is five years or more. Because of their subordinated position in the capital structure of an issuer, the ability to defer payments for extended periods of time without default consequences to the issuer, and certain other features (such as restrictions on common dividend payments by the issuer or ultimate guarantor when full cumulative payments on the trust preferred securities have not been made), these trust preferred securities are often treated as close substitutes for traditional preferred securities, both by issuers and investors. Trust preferred securities have many of the key characteristics of equity due to their subordinated position in an issuer’s capital structure and because their quality and value are heavily dependent on the profitability of the issuer rather than on any legal claims to specific assets or cash flows.

Convertible Securities

A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exchanged for a prescribed amount of common stock or other equity security of the same or a different issuer within a particular period of time at a specified price or formula. A convertible security entitles the holder to receive interest paid or accrued on debt or the dividend paid on preferred stock until the convertible security matures or is redeemed, converted or exchanged. Before conversion, convertible securities have characteristics similar to nonconvertible income securities in that they ordinarily provide a stable stream of income with generally higher yields than those of common stocks of the same or similar issuers, but lower yields than comparable nonconvertible securities. The value of a convertible security is influenced by changes in interest rates, with investment value declining as interest rates increase and increasing as interest rates decline. The credit standing of the issuer and other factors also may have an effect on the convertible security’s investment value. Convertible securities rank senior to common stock in a corporation’s capital structure but are usually subordinated to comparable nonconvertible securities. Convertible securities may be subject to redemption at the option of the issuer at a price established in the convertible security’s governing instrument.

A “synthetic” or “manufactured” convertible security may be created by the Fund or by a third party by combining separate securities that possess the two principal characteristics of a traditional convertible security: an income producing component and a convertible component. The income-producing component is achieved by investing in

non-convertible,

income-producing securities such as bonds, preferred stocks and money market instruments. The convertible component is achieved by investing in securities or instruments such as warrants or options to buy common stock at a certain exercise price, or options on a stock index. Unlike a traditional convertible security, which is a single security having a single market value, a synthetic convertible comprises two or more separate securities, each with its own market value. Because the “market value” of a synthetic convertible security is the sum of the values of its income-producing component and its convertible component, the value of a synthetic convertible security may respond differently to market fluctuations than a traditional convertible security. The Fund also may purchase synthetic convertible securities created by other parties, including convertible structured notes. Convertible structured notes are income-producing debentures linked to equity. Convertible structured notes have the attributes of a convertible security; however, the issuer of the convertible note (typically an investment bank), rather than the issuer of the underlying common stock into which the note is convertible, assumes credit risk associated with the underlying investment and the Fund in turn assumes credit risk associated with the issuer of the convertible note.

Restricted and Illiquid Investments

The Fund may invest without limitation in illiquid or less liquid investments or investments in which no secondary market is readily available or which are otherwise illiquid, including private placement securities. Liquidity of an investment relates to the ability to dispose easily of the investment and the price to be obtained upon disposition of the investment, which may be less than would be obtained for a comparable more liquid investment. “Illiquid investments” are investments which cannot be sold within seven days in the ordinary course of business at approximately the value used by the Fund in determining its NAV. Illiquid investments may trade at a discount

from comparable, more liquid investments. Illiquid investments are subject to legal or contractual restrictions on disposition or lack an established secondary trading market. Investment of the Fund’s assets in illiquid investments may restrict the ability of the Fund to dispose of its investments in a timely fashion and for a fair price as well as its ability to take advantage of market opportunities.

Non-U.S.

Securities

The Fund may invest in

Non-U.S.

Securities. These securities may be U.S. dollar-denominated or

non-U.S.

dollar-denominated. Some

Non-U.S.

Securities may be less liquid and more volatile than securities of comparable U.S. issuers. Similarly, there is less volume and liquidity in most foreign securities markets than in the United States and, at times, greater price volatility than in the United States. Because evidence of ownership of such securities usually is held outside the United States, the Fund will be subject to additional risks if it invests in

Non-U.S.

Securities, which include adverse political and economic developments, seizure or nationalization of foreign deposits and adoption of governmental restrictions which might adversely affect or restrict the payment of principal and interest or dividends on the foreign securities to investors located outside the country of the issuer, whether from currency blockage or otherwise.

Non-U.S.

Securities may trade on days when the common shares are not priced or traded.

Emerging Market Investments

The Fund may invest in securities of issuers located in emerging market countries, including securities denominated in currencies of emerging market countries. Emerging market countries generally include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. These issuers may be subject to risks that do not apply to issuers in larger, more developed countries. These risks are more pronounced to the extent the Fund invests significantly in one country. Less information about emerging market issuers or markets may be available due to less rigorous disclosure and accounting standards or regulatory practices. Emerging markets are smaller, less liquid and more volatile than U.S. markets. In a changing market, the Advisors may not be able to sell the Fund’s portfolio securities in amounts and at prices they consider reasonable. The U.S. dollar may appreciate against emerging market currencies or an emerging market government may impose restrictions on currency conversion or trading. The economies of

non-U.S.

countries may grow at a slower rate than expected or may experience a downturn or recession. Economic, political and social developments may adversely affect emerging market countries and their securities markets.

Equity Securities

The Fund may invest in equity securities, including common stocks, preferred stocks, convertible securities, warrants and rights and depositary receipts. Common stock represents an equity ownership interest in a company. The Fund may hold or have exposure to common stocks of issuers of any size, including small and medium capitalization stocks. Because the Fund will ordinarily have exposure to common stocks, historical trends would indicate that the Fund’s portfolio and investment returns will be subject at times, and over time, to higher levels of volatility and market and issuer-specific risk than if it invested exclusively in debt securities.

Warrants and Rights

Warrants and rights are instruments issued by corporations enabling the owners to subscribe to and purchase a specified number of shares of the corporation at a specified price during a specified period of time. Warrants and rights normally have a short life span to expiration. The purchase of warrants or rights involves the risk that the Fund could lose the purchase value of a warrant or right if the right to subscribe to additional shares is not exercised prior to the warrants’ and rights’ expiration. Also, the purchase of warrants and/or rights involves the risk that the effective price paid for the warrant and/or right added to the subscription price of the related security may exceed the subscribed security’s market price such as when there is no movement in the level of the underlying security.

The Fund may participate in rights offerings and may purchase warrants, which are privileges issued by corporations enabling the owners to subscribe to and purchase a specified number of shares of the corporation at a specified price during a specified period of time. Subscription rights normally have a short life span to expiration.

The purchase of rights or warrants involves the risk that the Fund could lose the purchase value of a right or warrant if the right to subscribe to additional shares is not exercised prior to the rights’ and warrants’ expiration. Also, the purchase of rights and/or warrants involves the risk that the effective price paid for the right and/or warrant added to the subscription price of the related security may exceed the value of the subscribed security’s market price such as when there is no movement in the level of the underlying security. Buying a warrant does not make the Fund a shareholder of the underlying stock. The warrant holder has no voting or dividend rights with respect to the underlying stock. A warrant does not carry any right to assets of the issuer, and for this reason investments in warrants may be more speculative than other equity-based investments.

Sovereign Governmental and Supranational Debt

The Fund may invest in all types of debt securities of governmental issuers in all countries, including foreign countries. These sovereign debt securities may include: debt securities issued or guaranteed by governments, governmental agencies or instrumentalities and political subdivisions located in foreign countries; debt securities issued by government owned, controlled or sponsored entities located in foreign countries; interests in entities organized and operated for the purpose of restructuring the investment characteristics of instruments issued by any of the above issuers; Brady Bonds, which are debt securities issued under the framework of the Brady Plan as a means for debtor nations to restructure their outstanding external indebtedness; participations in loans between emerging market governments and financial institutions; or debt securities issued by supranational entities such as the World Bank. A supranational entity is a bank, commission or company established or financially supported by the national governments of one or more countries to promote reconstruction or development. Sovereign government and supranational debt involve all the risks described herein regarding foreign and emerging markets investments as well as the risk of debt moratorium, repudiation or renegotiation.

Brady Bonds are not considered to be U.S. Government securities. U.S. dollar-denominated, collateralized Brady Bonds, which may be fixed rate par bonds or floating rate discount bonds, are generally collateralized in full as to principal by U.S. Treasury

zero-coupon

bonds having the same maturity as the Brady Bonds. Interest payments on these Brady Bonds generally are collateralized on a

one-year

or longer rolling-forward basis by cash or securities in an amount that, in the case of fixed rate bonds, is equal to at least one year of interest payments or, in the case of floating rate bonds, initially is equal to at least one year’s interest payments based on the applicable interest rate at that time and is adjusted at regular intervals thereafter. Certain Brady Bonds are entitled to “value recovery payments” in certain circumstances, which in effect constitute supplemental interest payments but generally are not collateralized. For example, some Mexican and Venezuelan Brady Bonds include attached value recovery options, which increase interest payments if oil revenues rise. Brady Bonds are often viewed as having three or four valuation components: (i) the collateralized repayment of principal at final maturity; (ii) the collateralized interest payments; (iii) the uncollateralized interest payments; and (iv) any uncollateralized repayment of principal at maturity (the uncollateralized amounts constitute the “residual risk”).

Brady Bonds involve various risk factors described elsewhere associated with investing in foreign securities, including the history of defaults with respect to commercial bank loans by public and private entities of countries issuing Brady Bonds. In light of the residual risk of Brady Bonds and, among other factors, the history of defaults, investments in Brady Bonds are considered speculative. There can be no assurance that Brady Bonds in which the Fund may invest will not be subject to restructuring arrangements or to requests for new credit, which may cause the Fund to suffer a loss of interest or principal on any of its holdings.

Inflation-Indexed Bonds

The Fund may invest in inflation-indexed bonds, which are fixed-income securities or other instruments whose principal value is periodically adjusted according to the rate of inflation. Two structures are common. The U.S. Treasury and some other issuers use a structure that accrues inflation into the principal value of the bond. Most other issuers pay out the Consumer Price Index (“CPI”) accruals as party of a semi-annual coupon.

1.5% semi-annually), and inflation over the first six months was 1%, the

mid-year

par value of the bond would be $1,010 and the first semi-annual interest payment would be $15.15 ($1,010 times 1.5%). If inflation during the second half of the year resulted in the whole year’s inflation equaling 3%, the

end-of-year

par value of the bond would be $1,030 and the second semi-annual interest payment would be $15.45 ($1,030 times 1.5%).

If the periodic adjustment rate measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and, consequently, the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds, even during a period of deflation. However, the current market value of the bonds is not guaranteed, and will fluctuate. The Fund may also invest in other inflation related bonds which may or may not provide a similar guarantee. If a guarantee of principal is not provided, the adjusted principal value of the bond repaid at maturity may be less than the original principal. In addition, if the Fund purchases inflation-indexed bonds offered by foreign issuers, the rate of inflation measured by the foreign inflation index may not be correlated to the rate of inflation in the United States.

The value of inflation-indexed bonds is expected to change in response to changes in real interest rates. Real interest rates, in turn, are tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if inflation were to rise at a faster rate than the nominal interest rates, real interest rates might decline, leading to an increase in value of inflation-indexed bonds. In contrast, if nominal interest rates increased at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-indexed bonds. There can be no assurance, however, that the value of inflation-indexed bonds will be directly correlated to changes in interest rates.

While these securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in value. If interest rates rise due to reasons other than inflation (for example, due to changes in currency exchange rates), investors in these securities may not be protected to the extent that the increase is not reflected in the bond’s inflation measure.

In general, the measure used to determine the periodic adjustment of U.S. inflation-indexed bonds is the Consumer Price Index for Urban Consumers

(“CPI-U”),

which is calculated monthly by the U.S. Bureau of Labor Statistics. The

CPI-U

is a measurement of changes in the cost of living, made up of components such as housing, food, transportation and energy. Inflation-indexed bonds issued by a foreign government are generally adjusted to reflect a comparable inflation index, calculated by that government. There can be no assurance that the

CPI-U

or any foreign inflation index will accurately measure the real rate of inflation in the prices of goods and services. Moreover, there can be no assurance that the rate of inflation in a foreign country will be correlated to the rate of inflation in the United States.

Any increase in the principal amount of inflation-indexed bond will be considered taxable ordinary income, even though investors do not received their principal until maturity.

Variable and Floating Rate Instruments

Variable and floating rate securities provide for a periodic adjustment in the interest rate paid on the obligations. The terms of such obligations provide that interest rates are adjusted periodically based upon an interest rate adjustment index as provided in the respective obligations. The adjustment intervals may be regular, and range from daily up to annually, or may be event-based, such as based on a change in the prime rate.

The interest rate on a floating rate security is a variable rate which is tied to another interest rate, such as a money-market index or Treasury bill rate. The interest rate on a floating rate security resets periodically, typically every six months. Because of the interest rate reset feature, floating rate securities provide the Fund with a certain degree of protection against rises in interest rates, although the Fund will participate in any declines in interest rates as well.

Inverse Floating Rate Securities

An inverse floater is a type of debt instrument that bears a floating or variable interest rate that moves in the opposite direction to interest rates generally or the interest rate on another security or index. Changes in interest rates generally, or the interest rate of the other security or index, inversely affect the interest rate paid on the inverse

floater, with the result that the inverse floater’s price will be considerably more volatile than that of a fixed rate bond. The Fund may invest in inverse floaters, which brokers typically create by depositing an income-producing instrument, including a mortgage related security, in a trust. The trust in turn issues a variable rate security and inverse floaters. The interest rate for the variable rate security is typically determined by an index or an auction process, while the inverse floater holder receives the balance of the income from the underlying income-producing instrument less an auction fee. The market prices of inverse floaters may be highly sensitive to changes in interest rates and prepayment rates on the underlying securities, and may decrease significantly when interest rates increase or prepayment rates change. In a transaction in which the Fund purchases an inverse floater from a trust, and the underlying security was held by the Fund prior to being deposited into the trust, the Fund typically treats the transaction as a secured borrowing for financial reporting purposes. As a result, for financial reporting purposes, the Fund will generally incur a

non-cash

interest expense with respect to interest paid by the trust on the variable rate securities and will recognize additional interest income in an amount directly corresponding to the

non-cash

interest expense. Therefore, the Fund’s NAV per common share and performance are not affected by the

non-cash

interest expense. This accounting treatment does not apply to inverse floaters acquired by the Fund when the Fund did not previously own the underlying bond.

Strategic Transactions and Other Management Techniques

The Fund may use a variety of other investment management techniques and instruments. The Fund may purchase and sell futures contracts, enter into various interest rate transactions such as swaps, caps, floors or collars, currency transactions such as currency forward contracts, currency futures contracts, currency swaps or options on currency or currency futures and swap contracts (including, but not limited to, credit default swaps) and may purchase and sell exchange-listed and

over-the-counter

put and call options on securities and swap contracts, financial indices and futures contracts and use other derivative instruments or management techniques, including derivative instruments that combine features of these instruments (collectively, “Strategic Transactions”). These Strategic Transactions may be used for duration management and other investment and risk management purposes, including to attempt to protect against possible changes in the market value of the Fund’s portfolio resulting from trends in the securities markets and changes in interest rates or to protect the Fund’s unrealized gains in the value of its portfolio securities, to facilitate the sale of portfolio securities for investment purposes, to establish a position in the securities markets as a temporary substitute for purchasing particular securities or to enhance income or gain. There is no particular strategy that requires use of one technique rather than another as the decision to use any particular strategy or instrument is a function of market conditions and the composition of the portfolio. The use of Strategic Transactions to enhance current income may be speculative. The ability of the Fund to use Strategic Transactions successfully will depend on the Advisors’ ability to predict pertinent market movements as well as sufficient correlation among the instruments, which cannot be assured. The use of Strategic Transactions may result in losses greater than if they had not been used, may require the Fund to sell or purchase portfolio securities at inopportune times or for prices other than current market values, may limit the amount of appreciation the Fund can realize on an investment or may cause the Fund to hold a security that it might otherwise sell. Certain provisions of the Code may restrict or affect the ability of the Fund to engage in Strategic Transactions. In addition, the use of certain Strategic Transactions may give rise to taxable income and have certain other consequences.

Swaps.

The Fund may enter into swap agreements, including interest rate and index swap agreements. Swap agreements are two party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than one year. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments. The gross returns to be exchanged or “swapped” between the parties are calculated with respect to a “notional amount,” i.e., the dollar amount invested at a particular interest rate, in a particular foreign currency, or in a “basket” of securities representing a particular index. The “notional amount” of the swap agreement is only a fictive basis on which to calculate the obligations that the parties to a swap agreement have agreed to exchange. The Fund’s obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the “net amount”).

Whether the Fund’s use of swap agreements will be successful in furthering its investment objectives will depend on the Advisors’ ability to correctly predict whether certain types of investments are likely to produce greater returns than other investments. 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. Swap

agreements also bear the risk that the Fund will not be able to meet its payment obligations to the counterparty. Restrictions imposed by the tax rules applicable to regulated investment companies may limit the Fund’s ability to use swap agreements. It is possible that developments in the swap market, including government regulation, could adversely affect the Fund’s ability to terminate existing swap agreements or to realize amounts to be received under such agreements.

Swaptions

. A swaption is a contract that gives a counterparty the right (but not the obligation) 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. The Fund may write (sell) and purchase put and call swaptions. Depending on the terms of the particular option agreement, the Fund may incur a greater degree of risk when it writes a swaption than it would incur when it purchases a swaption with the same terms. When the Fund purchases a swaption, 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 swaption, upon exercise of the option the Fund will become obligated according to the terms of the underlying agreement, and the Fund could be exposed to losses in excess of the amount of premium it received from the purchaser of the swaption.

Credit Default Swaps

. The Fund may enter into credit default swap agreements. The credit default swap agreement may have as reference obligations one or more securities that are not currently held by the Fund. The protection “buyer” in a credit default contract may be obligated to pay the protection “seller” an upfront or a periodic stream of payments over the term of the contract, provided that no credit event on the reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the “par value” (full notional amount) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or if the swap is cash settled the seller may be required to deliver the related net cash amount (the difference between the market value of the reference obligation and its par value). The Fund may be either the buyer or seller in the transaction. If the Fund is a buyer and no credit event occurs, the Fund will generally receive no payments from its counterparty under the swap if the swap is held through its termination date. However, if a credit event occurs, the buyer generally may elect to receive the full notional amount of the swap in exchange for an equal face amount of deliverable obligations of the reference entity, the value of which may have significantly decreased. As a seller, the Fund generally receives an upfront payment or a fixed rate of income throughout the term of the swap, which typically is between six months and three years, provided that there is no credit event. If a credit event occurs, generally the seller must pay the buyer the full notional amount of the swap in exchange for an equal face amount of deliverable obligations of the reference entity, the value of which may have significantly decreased. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its Managed Assets, the Fund would be subject to investment exposure on the notional amount of the swap in excess of any premium and margin required to establish and maintain the position.

Credit default swap agreements involve greater risks than if the Fund had taken a position in the reference obligation directly (either by purchasing or selling) since, in addition to general market risks, credit default swaps are subject to illiquidity risk, counterparty risk and credit risks. A buyer generally will also lose its upfront payment or any periodic payments it makes to the seller counterparty and receive no payments from its counterparty should no credit event occur and the swap is held to its termination date. If a credit event were to occur, the value of any deliverable obligation received by the seller, coupled with the upfront or periodic payments previously received, may be less than the full notional amount it pays to the buyer, resulting in a loss of value to the seller. A seller of a credit default swap or similar instrument is exposed to many of the same risks of leverage since, if a credit event occurs, the seller generally will be required to pay the buyer the full notional amount of the contract net of any amounts owed by the buyer related to its delivery of deliverable obligations.

In addition, the credit derivatives market is subject to a changing regulatory environment. It is possible that regulatory or other developments in the credit derivatives market could adversely affect the Fund’s ability to successfully use credit derivatives.

Total Return Swaps.

Total return swap agreements are contracts in which one party agrees to make periodic payments to another party based on the change in market value of the assets underlying the contract, which may include a specified security, basket of securities or securities indices during the specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. Total return swap agreements may be used to obtain exposure to a security or market without owning or taking physical

custody of such security or investing directly in such market. Total return swap agreements may effectively add leverage to the Fund’s portfolio because, in addition to its Managed Assets (as defined in the prospectus), the Fund would be subject to investment exposure on the notional amount of the swap in excess of any premium and margin required to establish and maintain the position.

Total return swap agreements are subject to market risk as well as the risk that a counterparty will default on its payment obligations to the Fund thereunder. Swap agreements also bear the risk that the Fund will not be able to meet its obligation to the counterparty. Generally, the Fund will enter into total return swaps on a net basis (i.e., the two payment streams are netted against one another with the Fund receiving or paying, as the case may be, only the net amount of the two payments).

Interest Rate Transactions

. The Fund may enter into interest rate swaps and purchase or sell interest rate caps and floors. The Fund expects to enter into these transactions primarily to preserve a return or spread on a particular investment or portion of its portfolio, as a duration management technique, to protect against any increase in the price of securities the Fund anticipates purchasing at a later date and/or to hedge against increases in the Fund’s costs associated with any leverage strategy. The Fund will ordinarily use these transactions as a hedge or for duration and risk management although it is permitted to enter into them to enhance income or gain. Interest rate swaps involve the exchange by the Fund with another party of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments with respect to a notional amount of principal). The purchase of an interest rate cap entitles the purchaser, to the extent that the level of a specified interest rate exceeds a predetermined interest rate (i.e., the strike price), to receive payments of interest on a notional principal amount from the party selling such interest rate cap. The purchase of an interest rate floor entitles the purchaser, to the extent that the level of a specified interest rate falls below a predetermined interest rate (i.e., the strike price), to receive payments of interest on a notional principal amount from the party selling such interest rate floor.

For example, if the Fund holds a debt instrument with an interest rate that is reset only once each year, it may swap the right to receive interest at this fixed rate for the right to receive interest at a rate that is reset every week. This would enable the Fund to offset a decline in the value of the debt instrument due to rising interest rates but would also limit its ability to benefit from falling interest rates. Conversely, if the Fund holds a debt instrument with an interest rate that is reset every week and it would like to lock in what it believes to be a high interest rate for one year, it may swap the right to receive interest at this variable weekly rate for the right to receive interest at a rate that is fixed for one year. Such a swap would protect the Fund from a reduction in yield due to falling interest rates and may permit the Fund to enhance its income through the positive differential between one week and one year interest rates, but would preclude it from taking full advantage of rising interest rates.

The Fund may hedge both its assets and liabilities through interest rate swaps, caps and floors. Usually, payments with respect to interest rate swaps will be made on a net basis (i.e., the two payment streams are netted out) with the Fund receiving or paying, as the case may be, only the net amount of the two payments on the payment dates. If there is a default by the other party to an uncleared interest rate swap transaction, generally the Fund will have contractual remedies pursuant to the agreements related to the transaction. With respect to interest rate swap transactions cleared through a central clearing counterparty, a clearing organization will be substituted for the counterparty and will guaranty the parties’ performance under the swap agreement. However, there can be no assurance that the clearing organization will satisfy its obligation to the Fund or that the Fund would be able to recover the full amount of assets deposited on its behalf with the clearing organization in the event of the default by the clearing organization or the Fund’s clearing broker. Certain U.S. federal income tax requirements may limit the Fund’s ability to engage in interest rate swaps. Distributions attributable to transactions in interest rate swaps generally will be taxable as ordinary income to shareholders.

Foreign Currency Transactions

. The Fund’s common shares are priced in U.S. dollars and the distributions paid by the Fund to common shareholders are paid in U.S. dollars. However, a portion of the Fund’s assets may be denominated in

non-U.S.

currencies and the income received by the Fund from such securities will be paid in

non-U.S.

currencies. The Fund also may invest in or gain exposure to

non-U.S.

currencies for investment or hedging purposes. The Fund’s investments in securities that trade in, or receive revenues in,

non-U.S.

currencies will be subject to currency risk, which is the risk that fluctuations in the exchange rates between the U.S. dollar and foreign currencies may negatively affect an investment. The Fund may (but is not required to) hedge some or all of

its exposure to

non-U.S.

currencies through the use of derivative strategies, including forward foreign currency exchange contracts, foreign currency futures contracts and options on foreign currencies and foreign currency futures. Suitable hedging transactions may not be available in all circumstances and there can be no assurance that the Fund will engage in such transactions at any given time or from time to time when they would be beneficial. Although the Fund has the flexibility to engage in such transactions, the Advisors may determine not to do so or to do so only in unusual circumstances or market conditions. These transactions may not be successful and may eliminate any chance for the Fund to benefit from favorable fluctuations in relevant foreign currencies. The Fund may also, to the extent applicable, use derivatives contracts for purposes of increasing exposure to a foreign currency or to shift exposure to foreign currency fluctuations from one currency to another.

Foreign Exchange Transactions

. The Fund may engage in spot and forward foreign exchange transactions and currency swaps, purchase and sell options on currencies and purchase and sell currency futures and related options thereon (collectively, “Currency Instruments”). Such transactions could be effected with respect to hedges on foreign dollar denominated securities owned by the Fund, sold by the Fund but not yet delivered, or committed or anticipated to be purchased by the Fund. As an illustration, the Fund may use such techniques to hedge the stated value in U.S. dollars of an investment in a

yen-denominated

security. In such circumstances, for example, the Fund may purchase a foreign currency put option enabling it to sell a specified amount of yen for dollars at a specified price by a future date. To the extent the hedge is successful, a loss in the value of the yen relative to the dollar will tend to be offset by an increase in the value of the put option. To offset, in whole or in part, the cost of acquiring such a put option, the Fund may also sell a call option which, if exercised, requires it to sell a specified amount of yen for dollars at a specified price by a future date (a technique called a “straddle”). By selling such a call option in this illustration, the Fund gives up the opportunity to profit without limit from increases in the relative value of the yen to the dollar. “Straddles” of the type that may be used by the Fund are considered to constitute hedging transactions. The Fund may not attempt to hedge any or all of its foreign portfolio positions.

Forward Foreign Currency Contracts

. The Fund may enter into forward currency contracts to purchase or sell foreign currencies for a fixed amount of U.S. dollars or another foreign currency. A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days (term) from the date of the forward currency contract agreed upon by the parties, at a price set at the time the forward currency contract is entered into. Forward currency contracts are traded directly between currency traders (usually large commercial banks) and their customers. The Fund may purchase a forward currency contract to lock in the U.S. dollar price of a security denominated in a foreign currency that the Fund intends to acquire. The Fund may sell a forward currency contract to lock in the U.S. dollar equivalent of the proceeds from the anticipated sale of a security or a dividend or interest payment denominated in a foreign currency. The Fund may also, to the extent applicable, use forward currency contracts to shift the Fund’s exposure to foreign currency exchange rate changes from one currency to another. For example, if the Fund owns securities denominated in a foreign currency and the Advisors believe that currency will decline relative to another currency, the Fund might enter into a forward currency contract to sell the appropriate amount of the first foreign currency with payment to be made in the second currency. The Fund may also, to the extent applicable, purchase forward currency contracts to enhance income when the Advisors anticipate that the foreign currency will appreciate in value but securities denominated in that currency do not present attractive investment opportunities. The Fund may also use forward currency contracts to hedge against a decline in the value of existing investments denominated in a foreign currency. Such a hedge would tend to offset both positive and negative currency fluctuations, but would not offset changes in security values caused by other factors. The Fund could also hedge the position by entering into a forward currency contract to sell another currency expected to perform similarly to the currency in which the Fund’s existing investments are denominated. This type of transaction could offer advantages in terms of cost, yield or efficiency, but may not hedge currency exposure as effectively as a simple forward currency transaction to sell U.S. dollars. This type of transaction may result in losses if the currency used to hedge does not perform similarly to the currency in which the hedged securities are denominated. The Fund may also use forward currency contracts in one currency or a basket of currencies to attempt to hedge against fluctuations in the value of securities denominated in a different currency if the Advisors anticipate that there will be a correlation between the two currencies.

The cost to the Fund of engaging in forward currency contracts varies with factors such as the currency involved, the length of the contract period and the market conditions then prevailing. Because forward currency contracts are usually entered into on a principal basis, no fees or commissions are usually involved. When the Fund enters into a forward currency contract, it relies on the counterparty to make or take delivery of the underlying

currency at the maturity of the contract. Failure by the counterparty to do so would result in the loss of some or all of any expected benefit of the transaction. Secondary markets generally do not exist for forward currency contracts, with the result that closing transactions generally can be made for forward currency contracts only by negotiating directly with the counterparty. Thus, there can be no assurance that the Fund will in fact be able to close out a forward currency contract at a favorable price prior to maturity. In addition, in the event of insolvency of the counterparty, the Fund might be unable to close out a forward currency contract. In either event, the Fund would continue to be subject to market risk with respect to the position. The precise matching of forward currency contract amounts and the value of the securities involved generally will not be possible because the value of such securities, measured in the foreign currency, will change after the forward currency contract has been established. Thus, the Fund might need to purchase or sell foreign currencies in the spot (cash) market to the extent such foreign currencies are not covered by forward currency contracts. The projection of short-term currency market movements is extremely difficult and the successful execution of a short-term hedging strategy is highly uncertain.

Call Options

. The Fund may purchase call options on any of the types of securities or instruments in which it may invest. A purchased call option gives the Fund the right to buy, and obligates the seller to sell, the underlying security at the exercise price at any time during the option period. The Fund also may purchase and sell call options on indices. Index options are similar to options on securities except that, rather than taking or making delivery of securities underlying the option at a specified price upon exercise, an index option gives the holder the right to receive cash upon exercise of the option if the level of the index upon which the option is based is greater than the exercise price of the option.

The Fund may write (i.e., sell) covered call options on the securities or instruments it holds and enter into closing purchase transactions with respect to certain of such options. A covered call option is an option in which the Fund, in return for a premium, gives another party a right to buy specified securities owned by the Fund at a specified future date and price set at the time of the contract. The principal reason for writing covered call options is the attempt to realize, through the receipt of premiums, a greater return than would be realized on the securities alone. Writing covered call options also serves as a partial hedge against declines in the price of the underlying security, to the extent of the premium received. By writing covered call options, the Fund gives up the opportunity, while the option is in effect, to profit from any price increase in the underlying security above the option exercise price. In addition, the Fund’s ability to sell the underlying security will be limited while the option is in effect unless the Fund enters into a closing purchase transaction. A closing purchase transaction cancels out the Fund’s position as the writer of an option by means of an offsetting purchase of an identical option prior to the expiration of the option it has written.

The Fund may write (i.e., sell) uncovered call options on securities or instruments in which it may invest but that are not currently held by the Fund. The principal reason for writing uncovered call options is to realize income without committing capital to the ownership of the underlying securities or instruments. When writing uncovered call options, the Fund must deposit and maintain sufficient margin with the broker-dealer through which it made the uncovered call option as collateral to ensure that the securities can be purchased for delivery if and when the option is exercised. During periods of declining securities prices or when prices are stable, writing uncovered calls can be a profitable strategy to increase the Fund’s income with minimal capital risk. Uncovered calls are riskier than covered calls because there is no underlying security held by the Fund that can act as a partial hedge. Uncovered calls have speculative characteristics and the potential for loss is unlimited. When an uncovered call is exercised, the Fund must purchase the underlying security to meet its call obligation. There is also a risk, especially with less liquid preferred and debt securities, that the securities may not be available for purchase. If the purchase price exceeds the exercise price, the Fund will lose the difference.

Put Options

. The Fund may purchase put options. By buying a put option, the Fund acquires a right to sell such underlying securities or instruments at the exercise price, thus limiting the Fund’s risk of loss through a decline in the market value of the securities or instruments until the put option expires. The amount of any appreciation in the value of the underlying securities or instruments will be partially offset by the amount of the premium paid for the put option and any related transaction costs. Prior to its expiration, a put option may be sold in a closing sale transaction and profit or loss from the sale will depend on whether the amount received is more or less than the premium paid for the put option plus the related transaction costs. A closing sale transaction cancels out the Fund’s position as the purchaser of an option by means of an offsetting sale of an identical option prior to the expiration of the option it has purchased.

The Fund also may write (i.e., sell) put options on securities or instruments in which it may invest but that the Fund does not currently have a corresponding short position or has not deposited cash equal to the exercise value of the put option with the broker-dealer through which it made the uncovered put option as collateral. The principal reason for writing such put options is to receive premium income and to acquire such securities or instruments at a net cost below the current market value. The Fund has the obligation to buy the securities or instruments at an agreed upon price if the securities or instruments decrease below the exercise price. If the securities or instruments price increases during the option period, the option will expire worthless and the Fund will retain the premium and will not have to purchase the securities or instruments at the exercise price.

In selling puts, there is a risk that the Fund may be required to buy the underlying security at a price higher than the current market price.

Financial Futures Transactions and Options

. The Fund is authorized to purchase and sell certain exchange traded financial futures contracts (“financial futures contracts”) in order to hedge its investments against declines in value, and to hedge against increases in the cost of securities it intends to purchase or to seek to enhance the Fund’s return. However, any transactions involving financial futures or options (including puts and calls associated therewith) will be in accordance with the Fund’s investment policies and limitations. A financial futures contract obligates the seller of a contract to deliver and the purchaser of a contract to take delivery of the type of financial instrument covered by the contract, or in the case of index-based futures contracts to make and accept a cash settlement, at a specific future time for a specified price. To hedge its portfolio, the Fund may take an investment position in a futures contract which will move in the opposite direction from the portfolio position being hedged. A sale of financial futures contracts may provide a hedge against a decline in the value of portfolio securities because such depreciation may be offset, in whole or in part, by an increase in the value of the position in the financial futures contracts. A purchase of financial futures contracts may provide a hedge against an increase in the cost of securities intended to be purchased because such appreciation may be offset, in whole or in part, by an increase in the value of the position in the futures contracts.

Distributions, if any, of net long term capital gains from certain transactions in futures or options are taxable at long term capital gains rates for U.S. federal income tax purposes.

Futures Contracts

. A futures contract is an agreement between two parties to buy and sell a security or, in the case of an index-based futures contract, to make and accept a cash settlement for a set price on a future date. A majority of transactions in futures contracts, however, do not result in the actual delivery of the underlying instrument or cash settlement, but are settled through liquidation, i.e., by entering into an offsetting transaction. Futures contracts have been designed by boards of trade which have been designated “contracts markets” by the Commodity Futures Trading Commission (the “CFTC”).

The purchase or sale of a futures contract differs from the purchase or sale of a security in that no price or premium is paid or received. Instead, an amount of cash or securities acceptable to the broker and the relevant contract market must be deposited with the broker. This amount is known as “initial margin” and represents a “good faith” deposit assuring the performance of both the purchaser and seller under the futures contract. Subsequent payments to and from the broker, called “variation margin,” are required to be made on a daily basis as the price of the futures contract fluctuates making the long and short positions in the futures contract more or less valuable, a process known as “marking to market.” At any time prior to the settlement date of the futures contract, the position may be closed out by taking an opposite position that will operate to terminate the position in the futures contract. A final determination of variation margin is then made, additional cash is required to be paid to or released by the broker and the purchaser realizes a loss or gain. In addition, a commission is paid on each completed sale transaction.

The Fund may also purchase and sell financial futures contracts on U.S. Government securities as a hedge against adverse changes in interest rates as described below. The Fund may purchase and write call and put options on futures contracts on U.S. Government securities in connection with its hedging strategies.

The Fund also may engage in other futures contracts transactions such as futures contracts on municipal bond indices that may become available if the Advisors should determine that there is normally a sufficient correlation between the prices of such futures contracts and securities in which the Fund invests to make such hedging appropriate.

Futures Strategies

. The Fund may sell a financial futures contract (i.e., assume a short position) in anticipation of a decline in the value of its investments resulting from an increase in interest rates or otherwise. The risk of decline could be reduced without employing futures as a hedge by selling investments and either reinvesting the proceeds in securities with shorter maturities or by holding assets in cash. This strategy, however, entails increased transaction costs in the form of dealer spreads and typically would reduce the average yield of the Fund’s portfolio securities as a result of the shortening of maturities. The sale of futures contracts provides an alternative means of hedging against declines in the value of its investments. As such values decline, the value of the Fund’s positions in the futures contracts will tend to increase, thus offsetting all or a portion of the depreciation in the market value of the Fund’s investments that are being hedged. While the Fund will incur commission expenses in selling and closing out futures positions, commissions on futures transactions are typically lower than transaction costs incurred in the purchase and sale of the Fund’s investments being hedged. In addition, the ability of the Fund to trade in the standardized contracts available in the futures markets may offer a more effective defensive position than a program to reduce the average maturity of the portfolio securities due to the unique and varied credit and technical characteristics of the instruments available to the Fund. Employing futures as a hedge also may permit the Fund to assume a defensive posture without reducing the yield on its investments beyond any amounts required to engage in futures trading.

When the Fund intends to purchase a security, the Fund may purchase futures contracts as a hedge against any increase in the cost of such security resulting from a decrease in interest rates or otherwise, that may occur before such purchase can be effected. Subject to the degree of correlation between such securities and futures contracts, subsequent increases in the cost of such securities should be reflected in the value of the futures held by the Fund. As such purchases are made, an equivalent amount of futures contracts will be closed out. Due to changing market conditions and interest rate forecasts, however, a futures position may be terminated without a corresponding purchase of portfolio securities.

Call Options on Futures Contracts

. The Fund may also purchase and sell exchange traded call and put options on financial futures contracts. The purchase of a call option on a futures contract is analogous to the purchase of a call option on an individual security. Depending on the pricing of the option compared to either the futures contract upon which it is based or the price of the underlying securities, it may or may not be less risky than ownership of the futures contract or underlying securities. Like the purchase of a futures contract, the Fund may purchase a call option on a futures contract to hedge against a market advance when the Fund is not fully invested.

The writing of a call option on a futures contract constitutes a partial hedge against declining prices of the securities which are deliverable upon exercise of the futures contract. If the futures price at expiration is below the exercise price, the Fund will retain the full amount of the option premium which provides a partial hedge against any decline that may have occurred in the Fund’s portfolio holdings.

Put Options on Futures Contracts

. The purchase of a put option on a futures contract is analogous to the purchase of a protective put option on portfolio securities. The Fund may purchase a put option on a futures contract to hedge the Fund’s portfolio against the risk of rising interest rates.

The writing of a put option on a futures contract constitutes a partial hedge against increasing prices of the securities which are deliverable upon exercise of the futures contract. If the futures price at expiration is higher than the exercise price, the Fund will retain the full amount of the option premium which provides a partial hedge against any increase in the price of securities which the Fund intends to purchase.

The writer of an option on a futures contract is required to deposit initial and variation margin pursuant to requirements similar to those applicable to futures contracts. Premiums received from the writing of an option will be included in initial margin. The writing of an option on a futures contract involves risks similar to those relating to futures contracts.

Additional Information About Options.

In the case of either put or call options that it has purchased, if the option expires without being sold or exercised, the Fund will experience a loss in the amount of the option

premium plus any commissions paid by the Fund. When the Fund sells put and call options, it receives a premium as the seller of the option. The premium that the Fund receives for selling the option will serve as a partial and limited (to the dollar amount of the premium) hedge, in the amount of the option premium, against changes in the value of the securities in its portfolio. During the term of the option, however, a covered call seller has, in return for the premium on the option, given up the opportunity for capital appreciation above the exercise price of the option if the value of the underlying security increases, but has retained the risk of loss should the price of the underlying security decline. Conversely, a put seller retains the risk of loss should the market value of the underlying security decline below the exercise price of the option, less the premium received on the sale of the option. The Fund may purchase and sell exchange-listed options and

over-the-counter

options (“OTC options”) which are privately negotiated with the counterparty. Listed options are issued by the Options Clearing Corporation (“OCC”), which acts as the central counterparty to the parties to such options.

The Fund’s ability to close out its position as a purchaser or seller of an exchange-listed put or call option is dependent upon the existence of a liquid secondary market on option exchanges. Among the possible reasons for the absence of a liquid secondary market on an exchange are: (i) insufficient trading interest in certain options; (ii) restrictions on transactions imposed by an exchange; (iii) trading halts, suspensions or other restrictions imposed with respect to particular classes or series of options or underlying securities; (iv) interruption of the normal operations on an exchange; (v) inadequacy of the facilities of an exchange or OCC to handle current trading volume; or (vi) a decision by one or more exchanges to discontinue the trading of options (or a particular class or series of options), in which event the secondary market on that exchange (or in that class or series of options) would cease to exist, although outstanding options on that exchange that had been listed by the OCC as a result of trades on that exchange would generally continue to be exercisable in accordance with their terms. OTC options are purchased from or sold to dealers, financial institutions or other counterparties which have entered into direct agreements with the Fund. With uncleared OTC options, such variables as expiration date, exercise price and premium will be agreed upon between the Fund and the counterparty, without the intermediation of a third party such as the OCC. If the counterparty fails to make or take delivery of the securities underlying an option it has written, or otherwise settle the transaction in accordance with the terms of that option as written, the Fund would lose the premium paid for the option as well as any anticipated benefit of the transaction. OTC options and assets used to cover OTC options written by the Fund may be illiquid. The illiquidity of such options or assets may prevent a successful sale of such options or assets, result in a delay of sale, or reduce the amount of proceeds that might otherwise be realized.

The hours of trading for options may not conform to the hours during which the underlying securities are traded or the hours of trading relevant to the determination of an index or other reference level. To the extent that the option markets close before the markets for the underlying securities, significant price and rate movements can take place in the underlying markets that cannot immediately be reflected in the option markets.

Hybrid Instruments

. A hybrid instrument is a type of potentially high-risk derivative that combines a traditional bond, stock or commodity with an option or forward contract. Generally, the principal amount, amount payable upon maturity or redemption, or interest rate of a hybrid is tied (positively or negatively) to the price of some commodity, currency or securities index or another interest rate or some other economic factor (each a “benchmark”). The interest rate or (unlike most fixed-income securities) the principal amount payable at maturity of a hybrid security may be increased or decreased, depending on changes in the value of the benchmark. An example of a hybrid could be a bond issued by an oil company that pays a small base level of interest with additional interest that accrues in correlation to the extent to which oil prices exceed a certain predetermined level. Such a hybrid instrument would be a combination of a bond and a call option on oil. Hybrids can be used as an efficient means of pursuing a variety of investment goals, including currency hedging, duration management and increased total return. Hybrids may not bear interest or pay dividends. The value of a hybrid or its interest rate may be a multiple of a benchmark and, as a result, may be leveraged and move (up or down) more steeply and rapidly than the benchmark. These benchmarks may be sensitive to economic and political events, such as commodity shortages and currency devaluations, which cannot be readily foreseen by the purchaser of a hybrid. Under certain conditions, the redemption value of a hybrid could be zero. Thus, an investment in a hybrid may entail significant market risks that are not associated with a similar investment in a traditional, U.S. dollar-denominated bond that has a fixed principal amount and pays a fixed rate or floating rate of interest. The purchase of hybrids also exposes the Fund to the credit risk of the issuer of the hybrids. These risks may cause significant fluctuations in the NAV of the Fund’s common shares if the Fund invests in hybrid instruments.

New Products

. The financial markets continue to evolve and financial products continue to be developed. The Fund reserves the right to invest in new financial products as they are developed or become more widely accepted. As with any new financial product, these products will entail risks, including risks to which the Fund currently is not subject.

The principal risks relating to the use of futures contracts and other Strategic Transactions are: (i) less than perfect correlation between the prices of the instrument and the market value of the securities in the Fund’s portfolio; (ii) possible lack of a liquid secondary market for closing out a position in such instruments; (iii) losses resulting from interest rate or other market movements not anticipated by the Advisors; and (iv) the obligation to meet additional variation margin or other payment requirements, all of which could result in the Fund being in a worse position than if such transactions had not been used.

Certain provisions of the Code may restrict or affect the ability of the Fund to engage in Strategic Transactions. See “Tax Matters.”

Structured Instruments

The Fund may use structured instruments for investment purposes, for risk management purposes, such as to reduce the duration and interest rate sensitivity of the Fund’s portfolio, for leveraging purposes and, with respect to certain structured instruments, as an alternative or complement to its options writing strategy. While structured instruments may offer the potential for a favorable rate of return from time to time, they also entail certain risks. Structured instruments may be less liquid than other securities and the price of structured instruments may be more volatile. In some cases, depending on the terms of the embedded index, a structured instrument may provide that the principal and/or interest payments may be adjusted below zero. Structured instruments also may involve significant credit risk and risk of default by the counterparty. Structured instruments may also be illiquid. Like other sophisticated strategies, the Fund’s use of structured instruments may not work as intended.

Structured Notes

. The Fund may invest in “structured” notes and other related instruments, which are privately negotiated debt obligations in which 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. Structured instruments may be issued by corporations, including banks, as well as by governmental agencies. Structured instruments frequently are assembled in the form of medium-term notes, but a variety of forms are available and may be used in particular circumstances. The terms of such structured instruments normally provide that their principal and/or interest payments are to be adjusted upwards or downwards (but ordinarily not 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 on 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(es) or other asset(s). Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss.

Event-Linked Securities

. The Fund may obtain event-linked exposure by investing in “event-linked bonds” or “event-linked swaps” or by implementing “event-linked strategies.” Event-linked exposure results in gains or losses that typically are contingent upon, or formulaically related to, defined trigger events. Examples of trigger events include hurricanes, earthquakes, weather-related phenomena or statistics relating to such events. Some event-linked bonds are commonly referred to as “catastrophe bonds.” If a trigger event occurs, the Fund may lose a portion of or its entire principal invested in the bond or the entire notional amount of a swap. Event-linked exposure often provides for an extension of maturity to process and audit loss claims when a trigger event has, or possibly has, occurred. An extension of maturity may increase volatility. Event-linked exposure may also expose the Fund to certain other risks including credit risk, counterparty risk, adverse regulatory or jurisdictional interpretations and adverse tax consequences. Event-linked exposures may also be subject to illiquidity risk.

Equity-Linked Notes

. Equity-linked notes are hybrid securities with characteristics of both fixed-income and equity securities. An equity-linked note is a debt instrument, usually a bond, that pays interest based upon the

performance of an underlying equity, which can be a single stock, basket of stocks or an equity index. Instead of paying a predetermined coupon, equity-linked notes link the interest payment to the performance of a particular equity market index or basket of stocks or commodities. The interest payment is typically based on the percentage increase in an index from a predetermined level, but alternatively may be based on a decrease in the index. The interest payment may in some cases be leveraged so that, in percentage terms, it exceeds the relative performance of the market. Equity-linked notes generally are subject to the risks associated with the securities of equity issuers, default risk and counterparty risk.

Credit Linked Notes

. A credit-linked note (“CLN”) is a derivative instrument. It is a synthetic obligation between two or more parties where the payment of principal and/or interest is based on the performance of some obligation (a reference obligation). In addition to the credit risk of the reference obligations and interest rate risk, the buyer/seller of the CLN is subject to counterparty risk.

Repurchase Agreements and Purchase and Sale Contracts

The Fund may enter into repurchase agreements. A repurchase agreement is a contractual agreement whereby the seller of securities 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 will be taxable. 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 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 Advisors 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 Advisors will demand additional collateral from the issuer to increase the value of the collateral to at least that of the repurchase price, including interest.

A purchase and sale contract is similar to a repurchase agreement, but differs from a repurchase agreement in that the contract arrangements stipulate that the securities are owned by the Fund. In the event of a default under such a repurchase agreement or a purchase and sale contract, instead of the contractual fixed rate of return, the rate of return to the Fund shall be dependent upon intervening fluctuations of the market value of such security and the accrued interest on the security. In such event, the Fund would have rights against the seller for breach of contract with respect to any losses arising from market fluctuations following the failure of the seller to perform.

Reverse Repurchase Agreements

Borrowings may be made by the Fund through reverse repurchase agreements under which the Fund sells portfolio securities to financial institutions, such as banks and broker-dealers, and agrees to repurchase them at an agreed upon date and price. Such agreements are considered to be borrowings under the Investment Company Act. The Fund may utilize reverse repurchase agreements when it is anticipated that the interest income to be earned from the investment of the proceeds of the transaction is greater than the interest expense of the transaction.

In accordance with Rule

18f-4

under the Investment Company Act, when the Fund engages in reverse repurchase agreements and similar financing transactions, the Fund may either (i) maintain asset coverage of at least 300% with respect to such transactions and any other borrowings in the aggregate, or (ii) treat such transactions as “derivatives transactions” and comply with Rule

18f-4

with respect to such transactions. See “Risk Factors in Strategic Transactions and Derivatives—Rule

18f-4

Under the Investment Company Act” in the SAI.

Short Sales

The Fund may make short sales of securities. A short sale is a transaction in which the Fund sells a security it does not own in anticipation that the market price of that security will decline. The Fund may make short sales to hedge positions, for duration and risk management, in order to maintain portfolio flexibility or, to the extent applicable, to enhance income or gain.

When the Fund makes a short sale, it must borrow the security sold short and deliver it to the broker-dealer through which it made the short sale as collateral for its obligation to deliver the security upon conclusion of the sale. The Fund may have to pay a fee to borrow particular securities and is often obligated to pay over to the securities lender any income, distributions or dividends received on such borrowed securities until it returns the security to the securities lender.

The Fund’s obligation to replace the borrowed security will be secured by collateral deposited with the securities lender, usually cash, U.S. government securities or other liquid assets. Depending on arrangements made with the securities lender regarding payment over of any income, distributions or dividends received by the Fund on such security, the Fund may not receive any payments (including interest) on its collateral deposited with such securities lender.

If the price of the security sold short increases between the time of the short sale and the time the Fund replaces the borrowed security, the Fund will incur a loss; conversely, if the price declines, the Fund will realize a gain. Any gain will be decreased, and any loss increased, by the transaction costs described above. Although the Fund’s gain is limited to the price at which it sold the security short, its potential loss is theoretically unlimited.

The Fund may also make short sales “against the box.” Short sales, even if covered, may represent a form of leverage and will create risks. In this type of short sale, at the time of the sale, the Fund owns or has the immediate and unconditional right to acquire at no additional cost the identical security.

The Fund must comply with Rule

18f-4

under the Investment Company Act with respect to its short sale borrowings, which are considered derivatives transactions under the Rule. See “Additional Risk Factors—Risk Factors in Strategic Transactions and Derivatives—Rule

18f-4

Under the Investment Company Act” in the SAI.

Bank Obligations

Bank obligations may include certificates of deposit, bankers’ acceptances and fixed time deposits. Certificates of deposit are negotiable certificates issued against funds deposited in a commercial bank for a definite period of time and earning a specified return. Bankers’ acceptances are negotiable drafts or bills of exchange, normally drawn by an importer or exporter to pay for specific merchandise, which are “accepted” by a bank, meaning, in effect, that the bank unconditionally agrees to pay the face value of the instrument on maturity. Fixed time deposits are bank obligations payable at a stated maturity date and bearing interest at a fixed rate. Fixed time deposits may be withdrawn on demand by the investor, but may be subject to early withdrawal penalties, which vary depending upon market conditions and the remaining maturity of the obligation. There are no contractual restrictions on the right to transfer a beneficial interest in a fixed time deposit to a third party, although there is no market for such deposits.

Obligations of foreign banks involve somewhat different investment risks than those affecting obligations of U.S. banks, including the possibilities that their liquidity could be impaired because of future political and economic developments, that their obligations may be less marketable than comparable obligations of U.S. banks, that a foreign jurisdiction might impose withholding taxes on interest income payable on those obligations, that foreign deposits may be seized or nationalized, that foreign governmental restrictions such as exchange controls may be adopted which might adversely affect the payment of principal and interest on those obligations and that the selection of those obligations may be more difficult because there may be less publicly available information concerning foreign banks or the accounting, auditing and financial reporting standards, practices and requirements applicable to foreign banks may differ from those applicable to U.S. banks. Foreign banks are not generally subject to examination by any U.S. Government agency or instrumentality.

Participation Notes

The Fund may buy participation notes from a bank or broker-dealer (“issuer”) that entitle the Fund to a return measured by the change in value of an identified underlying security or basket of securities (collectively, the “underlying security”). Participation notes are typically used when a direct investment in the underlying security is restricted due to country-specific regulations.

The Fund is subject to counterparty risk associated with each issuer. Investment in a participation note is not the same as investment in the constituent shares of the company. A participation note represents only an obligation of the issuer to provide the Fund the economic performance equivalent to holding shares of an underlying security. A participation note does not provide any beneficial or equitable entitlement or interest in the relevant underlying security. In other words, shares of the underlying security are not in any way owned by the Fund. However each participation note synthetically replicates the economic benefit of holding shares in the underlying security. Because a participation note is an obligation of the issuer, rather than a direct investment in shares of the underlying security, the Fund may suffer losses potentially equal to the full value of the participation note if the issuer fails to perform its obligations.

The counterparty may, but is not required to, purchase the shares of the underlying security to hedge its obligation. The Fund may, but is not required to, purchase credit protection against the default of the issuer. When the participation note expires or the Fund exercises the participation note and closes its position, the Fund receives a payment that is based upon the then-current value of the underlying security converted into U.S. dollars (less transaction costs). The price, performance and liquidity of the participation note are all linked directly to the underlying security. The Fund’s ability to redeem or exercise a participation note generally is dependent on the liquidity in the local trading market for the security underlying the participation note.

When-Issued, Delayed Delivery Securities and Forward Commitment Securities

The Fund may purchase securities on a “when-issued” basis and may purchase or sell securities on a “forward commitment” basis (including on a “TBA” (to be announced) basis) or on a “delayed delivery” basis. When such transactions are negotiated, the price, which is generally expressed in yield terms, is fixed at the time the commitment is made, but delivery and payment for the securities take place at a later date. When-issued securities and forward commitments may be sold prior to the settlement date. If the Fund disposes of the right to acquire a when-issued security prior to its acquisition or disposes of its right to deliver or receive against a forward commitment, it might incur a gain or loss. The value of these assets will be monitored daily to ensure that their marked to market value will at all times equal or exceed the corresponding obligations of the Fund. Pursuant to recommendations of the Treasury Market Practices Group, which is sponsored by the Federal Reserve Board of New York, the Fund or its counterparty generally is required to post collateral when entering into certain forward-settling transactions, including without limitation TBA transactions.

There is always a risk that the securities may not be delivered and that the Fund may incur a loss. A default by a counterparty may result in the Fund missing the opportunity of obtaining a price considered to be advantageous. The value of securities in these transactions on the delivery date may be more or less than the Fund’s purchase price. The Fund may bear the risk of a decline in the value of the security in these transactions and may not benefit from an appreciation in the value of the security during the commitment period. Settlements in the ordinary course are not treated by the Fund as when-issued or forward commitment transactions and accordingly are not subject to the foregoing restrictions.

The market value of the securities underlying a commitment to purchase securities, and any subsequent fluctuations in their market value, is taken into account when determining the NAV of the Fund starting on the day the Fund agrees to purchase the securities. The Fund does not earn interest on the securities it has committed to purchase until they are paid for and delivered on the settlement date.

Rule

18f-4

under the Investment Company Act permits the Fund to enter into when-issued or forward-settling securities (e.g., firm and standby commitments, including

to-be-announced

(“TBA”) commitments, and dollar rolls) and

non-standard

settlement cycle securities notwithstanding the limitation on the issuance of senior securities in Section 18 of the Investment Company Act, provided that the Fund intends to physically settle the transaction and

the transaction will settle within 35 days of its trade date (the “Delayed-Settlement Securities Provision”). If a when-issued, forward-settling or

non-standard

settlement cycle security does not satisfy the Delayed-Settlement Securities Provision, then it is treated as a derivatives transaction under Rule

18f-4.

See “Additional Risk Factors—Risk Factors in Strategic Transactions and Derivatives—Rule

18f-4

Under the Investment Company Act” in the SAI.

Standby Commitment Agreements

The Fund from time to time may enter into standby commitment agreements. Such agreements commit the Fund, for a stated period of time, to purchase a stated amount of a fixed-income security that may be issued and sold to the Fund at the option of the issuer. The price and coupon of the security is fixed at the time of the commitment. At the time of entering into the agreement the Fund may be paid a commitment fee, regardless of whether or not the security ultimately is issued. The Fund will enter into such agreements only for the purpose of investing in the security underlying the commitment at a yield and price which is considered advantageous to the Fund. The Fund at all times will designate on its books and records cash or other liquid assets with a value equal to the purchase price of the securities underlying the commitment.

There can be no assurance that the securities subject to a standby commitment will be issued and the value of the security, if issued, on the delivery date may be more or less than its purchase price. Since the issuance of the security underlying the commitment is at the option of the issuer, the Fund may bear the risk of decline in the value of such security and may not benefit from an appreciation in the value of the security during the commitment period.

The purchase of a security subject to a standby commitment agreement and the related commitment fee will be recorded on the date on which the security reasonably can be expected to be issued and the value of the security thereafter will be reflected in the calculation of the Fund’s NAV. The cost basis of the security will be adjusted by the amount of the commitment fee. In the event the security is not issued, the commitment fee will be recorded as income on the expiration date of the standby commitment.

Temporary Defensive Positions

During temporary defensive periods, if the Advisors determine that market conditions warrant, and also during the period in which the net proceeds of this offering of common shares (or preferred shares, should the Fund determine to issue preferred shares in the future) are being invested, the Fund may invest any percentage of its assets without limitation in cash, cash equivalents, money market securities, such as U.S. Treasury and agency obligations, other U.S. Government securities, short-term debt obligations of corporate issuers, certificates of deposit, bankers acceptances, commercial paper (short-term, unsecured, negotiable promissory notes of a domestic or foreign issuer), repurchase agreements, obligations of supranational organizations, bank obligations, including U.S. subsidiaries and branches of foreign banks, or other high quality fixed-income securities. Temporary defensive positions may affect the Fund’s ability to achieve its investment objectives. Generally, such obligations will mature within one year from the date of settlement, but may mature within two years from the date of settlement.

Cash Equivalents and Short-Term Debt Securities

For temporary defensive purposes or to keep cash on hand fully invested, the Fund may invest up to 100% of its total assets in cash equivalents and short-term debt securities.

Taxable short-term debt securities are defined to include, without limitation:

(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 securities include securities issued by (a) the FHA, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration and GNMA, whose securities are supported by the full faith and credit of the United States; (b) the FHLBs, Federal Intermediate Credit Banks, and Tennessee Valley Authority, whose securities are supported by the right of the agency to borrow from the U.S. Treasury; (c) FNMA, 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;

(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. Certificates of deposit purchased by the Fund may not be fully insured by the Federal Deposit Insurance Corporation.

(3) Repurchase agreements, which involve purchases of debt securities;

(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 Advisors 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.

Tax-exempt

short-term debt securities are defined to include, without limitation:

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

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

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

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

(5) Bank notes are notes issued by local government bodies and agencies 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 on 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 tax-exempt money market indices.

While the various types of notes described above as a group represent the major portion of the 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.

Counterparty Credit Standards

To the extent that the Fund engages in principal transactions, including, but not limited to, OTC options, forward currency transactions, swap transactions, repurchase and reverse repurchase agreements and the purchase and sale of bonds and other fixed-income securities, it must rely on the creditworthiness of its counterparties under such transactions. In certain instances, the credit risk of a counterparty is increased by the lack of a central clearing house for certain transactions, including certain swap contracts. In the event of the insolvency of a counterparty, the Fund may not be able to recover its assets, in full or at all, during the insolvency process. Counterparties to investments may have no obligation to make markets in such investments and may have the ability to apply essentially discretionary margin and credit requirements. Similarly, the Fund will be subject to the risk of bankruptcy of, or the inability or refusal to perform with respect to such investments by, the counterparties with which it deals. The Advisors will seek to minimize the Fund’s exposure to counterparty risk by entering into such transactions with counterparties the Advisors believe to be creditworthy at the time it enters into the transaction. Certain transactions, including option transactions and Strategic Transactions may require the Fund to provide collateral to secure its performance obligations under a contract, which would also entail counterparty credit risk.

Securities Lending

The Fund may lend portfolio securities to certain borrowers determined to be creditworthy by the Advisors, including to borrowers affiliated with the Advisors. The borrowers provide collateral that is maintained in an amount at least equal to the current market value of the securities loaned. As a result of limitations under the Investment Company Act and SEC staff guidance, no securities loan shall be made on behalf of the Fund if, as a result, the aggregate value of all securities loans of the Fund exceeds one-third of the value of the Fund’s total assets (including the value of the collateral received). The Fund may terminate a loan at any time and obtain the return of the securities loaned. The Fund receives the value of any interest or cash or non-cash distributions paid on the loaned securities.

With respect to loans that are collateralized by cash, the borrower may be entitled to receive a fee based on the amount of cash collateral. The Fund is compensated by the difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, the Fund is compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral received by the Fund for such loans, and uninvested cash, may be invested, among other things, in a private investment company managed by an affiliate of the Advisors or in registered money market funds advised by the Advisors or their affiliates; such investments are subject to investment risk.

The Fund conducts its securities lending pursuant to an exemptive order from the SEC permitting it to lend portfolio securities to borrowers affiliated with the Fund and to retain an affiliate of the Fund as lending agent. To the extent that the Fund engages in securities lending, BlackRock Investment Management, LLC (“BIM”), an affiliate of the Advisors, acts as securities lending agent for the Fund, subject to the overall supervision of the Advisors. BIM administers the lending program in accordance with guidelines approved by the Board. Pursuant to the current securities lending agreement, BIM may lend securities only when the difference between the borrower rebate rate and the risk free rate exceeds a certain level.

To the extent that the Fund engages in securities lending, the Fund retains a portion of securities lending income and remits a remaining portion to BIM as compensation for its services as securities lending agent. Securities lending income is equal to the total of income earned from the reinvestment of cash collateral (and excludes collateral investment expenses as defined below), and any fees or other payments to and from borrowers of securities. As securities lending agent, BIM bears all operational costs directly related to securities lending. The Fund is responsible for expenses in connection with the investment of cash collateral received for securities on loan in a private investment company managed by an affiliate of the Advisors (the “collateral investment expenses”); however, BIM has agreed to cap the collateral investment expenses the Fund bears to an annual rate of 0.04% of the daily net assets of such private investment company. In addition, in accordance with the exemptive order, the investment adviser to the private investment company will not charge any advisory fees with respect to shares purchased by the Fund. Such shares also will not be subject to a sales load, redemption fee, distribution fee or service fee.

Pursuant to the current securities lending agreement, the Fund retains 82% of securities lending income (which excludes collateral investment expenses).

In addition, commencing the business day following the date that the aggregate securities lending income earned across the BlackRock Fixed-Income Complex (as defined in the SAI) in a calendar year exceeds the breakpoint dollar threshold applicable in the given year, the Fund, pursuant to the current securities lending agreement, will receive for the remainder of that calendar year securities lending income in an amount equal to 85% of securities lending income (which excludes collateral investment expenses).

Risk Factors [Table Text Block]

RISKS

The NAV and market price of, and dividends paid on, the common shares will fluctuate with and be affected by, among other things, the risks of investing in the Fund.

General Risks

Please refer to the section of the Fund’s most recent annual report on Form N-CSR entitled “Investment Objectives, Policies and Risks—Risk Factors”, which is incorporated by reference herein, for a discussion of the general risks of investing in the Fund.

Other Risks

Offering Risk

. The provisions of the Investment Company Act generally require that the public offering price of an investment company’s common stock (less any underwriting commissions and discounts) must equal or exceed the NAV per share of an investment company’s common stock (calculated within 48 hours of pricing). In the offering described in this Prospectus, the Fund may, subject to market conditions, raise additional equity capital by issuing new common stock from time to time in varying amounts at a net price at or above the Fund’s NAV per common share (calculated within 48 hours of pricing). To the extent that Fund shares do not trade at a premium, the Fund may be unable to issue additional shares, and may incur costs associated with setting up and maintaining an “at the market” program without the potential benefits. The offering described in this Prospectus may allow the Fund to pursue additional investment opportunities without the need to sell existing portfolio investments and will increase the asset size of the Fund and thus cause the Fund’s fixed expenses to be spread over a larger asset base. However, the issuance may not necessarily result in an increase to net income for shareholders, which depends on leverage levels, the comparison between book yields on existing assets, available investment opportunities and other factors. The Fund cannot predict whether its common stock will trade in the future at a premium or discount to their NAV per share. Shares of common stock of closed-end investment companies frequently trade at a discount from NAV, which may increase investors’ risk of loss. In no event will shares be issued at a price below the Fund’s NAV per common share (calculated within 48 hours of pricing) plus any sales commission charged in connection with the offering.

The offering described in this Prospectus entails potential risks to existing common shareholders. Although the issuance of additional common stock may facilitate a more active market in the Fund’s common stock by increasing the amount of common stock outstanding, the issuance of additional common stock may also have an adverse effect on prices for the Fund’s common stock in the secondary market by increasing the supply of common stock available for sale. The issuance of additional common stock will dilute the voting power of already outstanding common stock. If the Fund is unable to invest the proceeds of any such offering in a timely

manner

in assets with a yield at least equal to that of the current portfolio, the Fund’s earnings per share may decrease.

Second Lien Loans Risk

. Second lien loans generally are subject to similar risks as those associated with investments in senior loans. Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. This risk is generally higher for subordinated unsecured loans or debt, which are not backed by a security interest in any specific collateral. Second lien loans generally have greater price volatility than senior loans and may be less liquid. Second lien loans share the same risks as other below investment grade securities.

Mezzanine Investment Risk

. Mezzanine securities generally are rated below investment grade and frequently are unrated and present many of the same risks as senior loans, second lien loans and non-investment grade bonds. However, unlike senior loans and second lien loans, mezzanine securities are not a senior or secondary secured obligation of the related borrower. They typically are the most subordinated debt obligation in an issuer’s capital structure. Mezzanine securities also may often be unsecured. Mezzanine securities therefore are subject to the additional risk that the cash flow of the related borrower and the property securing the loan may be insufficient to repay the scheduled principal after giving effect to any senior obligations of the related borrower. Mezzanine securities are also expected to be a highly illiquid investment. Mezzanine securities will be subject to certain additional risks to the extent that such loans may not be protected by financial covenants or limitations upon additional indebtedness. Investment in mezzanine securities is a highly specialized investment practice that depends more heavily on independent credit analysis than investments in other types of debt obligations.

Risks of Loan Assignments and Participations

. As the purchaser of an assignment, the Fund typically succeeds to all the rights and obligations of the assigning institution and becomes a lender under the credit agreement with respect to the debt obligation; however, the Fund may not be able to unilaterally enforce all rights and remedies under the loan and with regard to any associated collateral. Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations

acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment a portion of any fees to which the Fund is entitled under the loan. A participation typically results in a contractual relationship only with the institution participating out the interest, not with the borrower. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower.

Bank Loans Risk

. The market for bank loans may not be highly liquid and the Fund may have difficulty selling them. These investments are subject to both interest rate risk and credit risk. These investments expose the Fund to the credit risk of both the financial institution and the underlying borrower.

Corporate Bonds Risk

. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates. The market value of intermediate and longer-term corporate bonds is generally more sensitive to changes in interest rates than is the market value of shorter-term corporate bonds. The market value of a corporate bond also may be affected by factors directly related to the issuer, such as investors’ perceptions of the creditworthiness of the issuer, the issuer’s financial performance, perceptions of the issuer in the market place, performance of management of the issuer, the issuer’s capital structure and use of financial leverage and demand for the issuer’s goods and services. Certain risks associated with investments in corporate bonds are described elsewhere in this Prospectus in further detail. There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument. Corporate bonds of below investment grade quality are often high risk and have speculative characteristics and may be particularly susceptible to adverse issuer-specific developments.

Yield and Ratings Risk

. The yields on certain debt obligations are dependent on a variety of factors, including general market conditions, conditions in the particular market for the obligation, the financial condition of the issuer, the size of the offering, the maturity of the obligation and the ratings of the issue. The ratings of Moody’s, S&P and Fitch, which are described in Appendix A to the SAI, represent their respective opinions as to the quality of the obligations they undertake to rate. Ratings, however, are general and are not absolute standards of quality. Consequently, obligations with the same rating, maturity and interest rate may have different market prices. Subsequent to its purchase by the Fund, a rated security may cease to be rated. The Advisors will consider such an event in determining whether the Fund should continue to hold the security.

Unrated Securities Risk

. Because the Fund may purchase securities that are not rated by any rating organization, the Advisors may, after assessing their credit quality, internally assign ratings to certain of those securities in categories similar to those of rating organizations. 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 Advisors’ credit analysis than would be the case when the Fund invests in rated securities.

Debtor-In-Possession (DIP) Financing Risk

. The Fund’s participation in DIP financings is subject to risks. DIP financings are arranged when an entity seeks the protections of the bankruptcy court under Chapter 11 of the U.S. Bankruptcy Code and must be approved by the bankruptcy court. These financings allow the entity to continue its business operations while reorganizing under Chapter 11. DIP financings are typically fully secured by a lien on the debtor’s otherwise unencumbered assets or secured by a junior lien on the debtor’s encumbered assets (so long as the loan is fully secured based on the most recent current valuation or appraisal report of the debtor). DIP financings are often required to close with certainty and in a rapid manner in order to satisfy existing creditors and to enable the issuer to emerge from bankruptcy or to avoid a bankruptcy proceeding. There is a risk that the borrower will not emerge from Chapter 11 bankruptcy proceedings and be forced to liquidate its assets under Chapter 7 of the U.S. Bankruptcy Code. In the event of liquidation, the Fund’s only recourse will be against the property securing the DIP financing.

Mortgage Related Securities Risks

. Investing in MBS entails various risks. MBS represent an interest in a pool of mortgages. The risks associated with MBS include: credit risk associated with the performance of the underlying mortgage properties and of the borrowers owning these properties; risks associated with their structure and execution (including the collateral, the process by which principal and interest payments are allocated and distributed to investors and how credit losses affect issuing vehicles and the return to investors in such MBS); whether the collateral represents a fixed set of specific assets or accounts, whether the underlying collateral assets are revolving or closed-end, under what terms (including maturity of the MBS) any remaining balance in the accounts may revert to the issuing entity and the extent to which the entity that is the actual source of the collateral assets is obligated to provide support to the issuing vehicle or to the investors in such MBS; risks associated with the servicer of the underlying mortgages; adverse changes in economic conditions and circumstances, which are more likely to have an adverse impact on MBS secured by loans on certain types of commercial properties than on those secured by loans on residential properties; prepayment risk, which can lead to significant fluctuations in the value of the MBS; loss of all or part of the premium, if any, paid; and decline in the market value of the security, whether resulting from changes in interest rates, prepayments on the underlying mortgage collateral or perceptions of the credit risk associated with the underlying mortgage collateral. In addition, the Fund’s level of investment in MBS of a particular type or in MBS issued or guaranteed by affiliated obligors, serviced by the same servicer or backed by underlying collateral located in a specific geographic region, may subject the Fund to additional risk. To the extent the Fund invests in junior tranches of MBS, it will be subject to additional risks, such as the risk that the proceeds that would otherwise be distributed to the Fund will be used to pay down more senior tranches.

When market interest rates decline, more mortgages are refinanced and the securities are paid off earlier than expected. Prepayments may also occur on a scheduled basis or due to foreclosure. During such periods, the reinvestment of prepayment proceeds by the Fund will generally be at lower rates than the rates that were carried by the obligations that have been prepaid. When market interest rates increase, the market values of MBS decline. At the same time, however, mortgage refinancings and prepayments slow, lengthening the effective maturities of these securities. As a result, the negative effect of the rate increase on the market value of MBS is usually more pronounced than it is for other types of fixed-income securities. Moreover, the relationship between borrower prepayments and changes in interest rates may mean some high-yielding mortgage-related and other asset-backed securities have less potential for increases in value if market interest rates were to fall than conventional bonds with comparable maturities.

In general, losses on a mortgaged property securing a mortgage loan included in a securitization will be borne first by the equity holder of the property, then by a cash reserve fund or letter of credit, if any, then by the holder of a mezzanine loan or B-Note, if any, then by the “first loss” subordinated security holder (generally, the “B-Piece” buyer) and then by the holder of a higher rated security. The Fund could invest in any class of security included in a securitization. In the event of default and the exhaustion of any equity support, reserve fund, letter of credit, mezzanine loans or B-Notes, and any classes of securities junior to those in which the Fund invests, the Fund will not be able to recover all of its investment in the MBS it purchases. MBS in which the Fund invests may not contain reserve funds, letters of credit, mezzanine loans and/or junior classes of securities. The prices of lower credit quality securities are generally less sensitive to interest rate changes than more highly rated investments, but more sensitive to adverse economic downturns or individual issuer developments.

MBS generally are classified as either RMBS or CMBS, each of which are subject to certain specific risks as further described below.

RMBS Risks

. RMBS are securities the payments on which depend primarily on the cash flow from residential mortgage loans made to borrowers that are secured by residential real estate. Non-agency residential mortgage loans are obligations of the borrowers thereunder only and are not typically insured or guaranteed by any other person or entity. The ability of a borrower to repay a loan secured by residential property is dependent upon the income or assets of the borrower. A number of factors, including general economic downturn, acts of God, terrorism, social unrest and civil disturbances, may impair a borrower’s ability to repay its loans.

Agency RMBS Risks

. MBS issued by FNMA or FHLMC are guaranteed as to timely payment of principal and interest by FNMA or FHLMC, but are not backed by the full faith and credit of the U.S. Government. In 2008, FHFA placed FNMA and FHLMC into conservatorship. FNMA and FHLMC are continuing to operate as going concerns while in conservatorship and each remains liable for all of its obligations, including its guaranty obligations, associated with its MBS. As the conservator, FHFA succeeded to all rights, titles, powers and privileges of FNMA and FHLMC and of any stockholder, officer or director of FNMA and FHLMC with respect to FNMA and FHLMC and the assets of FNMA and FHLMC. In connection with the conservatorship, the U.S. Treasury entered into an agreement with each of FNMA and FHLMC that contains various covenants that severely limit each enterprise’s operations. There is no assurance that the obligations of such entities will be satisfied in full, or that such obligations will not decrease in value or default.

Under the Reform Act, FHFA, as conservator or receiver, has the power to repudiate any contract entered into by FNMA or FHLMC prior to FHFA’s appointment as conservator or receiver, as applicable, if FHFA determines, in its sole discretion, that performance of the contract is burdensome and that repudiation of the contract promotes the orderly administration of FNMA’s or FHLMC’s affairs. In the event that FHFA, as conservator of, or if it is later appointed as receiver for, FNMA or FHLMC, were to repudiate any such guaranty obligation, the conservatorship or receivership estate, as applicable, would be liable for actual direct compensatory damages in accordance with the provisions of the Reform Act. Any such liability could be satisfied only to the extent of FNMA’s or FHLMC’s assets available therefor. In the event of repudiation, the payments of interest to holders of FNMA or FHLMC MBS would be reduced if payments on the mortgage loans represented in the mortgage loan groups related to such MBS are not made by the borrowers or advanced by the servicer. Any actual direct compensatory damages for repudiating these guaranty obligations may not be sufficient to offset any shortfalls experienced by such MBS holders. Further, in its capacity as conservator or receiver, FHFA has the right to transfer or sell any asset or liability of FNMA or FHLMC without any approval, assignment or consent. If FHFA, as conservator or receiver, were to transfer any such guaranty obligation to another party, holders of FNMA or FHLMC MBS would have to rely on that party for satisfaction of the guaranty obligation and would be exposed to the credit risk of that party. In addition, certain rights provided to holders of MBS issued by FNMA and FHLMC under the operative documents related to such securities may not be enforced against FHFA, or enforcement of such rights may be delayed, during the conservatorship or any future receivership. The operative documents for FNMA and FHLMC MBS may provide (or with respect to securities issued prior to the date of the appointment of the conservator may have provided) that upon the occurrence of an event of default on the part of FNMA or FHLMC, in its capacity as guarantor, which includes the appointment of a conservator or receiver, holders of such MBS have the right to replace FNMA or FHLMC as trustee if the requisite percentage of MBS holders consent. The Reform Act prevents MBS holders from enforcing such rights if the event of default arises solely because a conservator or receiver has been appointed.

Non-Agency RMBS Risks

. Non-agency RMBS are securities issued by non-governmental issuers. Non-agency RMBS have no direct or indirect government guarantees of payment and are subject to various risks as described herein.

Borrower Credit Risk

Credit-related risk on RMBS arises from losses due to delinquencies and defaults by the borrowers in payments on the underlying mortgage loans and breaches by originators and servicers of their obligations under the underlying documentation pursuant to which the RMBS are issued. Non-agency residential mortgage loans are obligations of the borrowers thereunder only and are not typically insured or guaranteed by any other person or entity. The rate of delinquencies and defaults on residential mortgage loans and the aggregate amount of the resulting losses will be affected by a number of factors, including general economic conditions, particularly those in the area where the related mortgaged property is located, the level of the borrower’s equity in the mortgaged property and the individual financial circumstances of the borrower. If a residential mortgage loan is in default, foreclosure on the related residential property may be a lengthy and difficult process involving significant legal and other expenses. The net proceeds obtained by the holder on a residential mortgage loan following the foreclosure on the related property may be less than the total amount that remains due on the loan. The prospect of incurring a loss upon the foreclosure of the related property may lead the holder of the residential mortgage loan to restructure the residential mortgage loan or otherwise delay the foreclosure process

RMBS Legal Risks

. Legal risks associated with RMBS can arise as a result of the procedures followed in connection with the origination of the mortgage loans or the servicing thereof, which may be subject to various federal and state laws (including, without limitation, predatory lending laws), public policies and principles of equity that regulate interest rates and other charges, require certain disclosures, require licensing of originators, prohibit discriminatory lending practices, regulate the use of consumer credit information and debt collection practices and may limit the servicer’s ability to collect all or part of the principal of or interest on a residential mortgage loan, entitle the borrower to a refund of amounts previously paid by it or subject the servicer to damages and sanctions. Specifically, provisions of federal predatory lending laws, such as the federal Truth-in-Lending Act (as supplemented by the Home Ownership and Equity Protection Act of 1994) and Regulation Z, and various recently enacted state predatory lending laws provide that a purchaser or assignee of specified types of residential mortgage loans (including an issuer of RMBS) may be held liable for violations by the originator of such mortgage loans. Under such assignee liability provisions, a borrower is generally given the right to assert against a purchaser of its mortgage loan any affirmative claims and defenses to payment that such borrower could assert against the originator of the loan or, where applicable, the home improvement contractor that arranged the loan. Liability under such assignee liability provisions could, therefore, result in a disruption of cash flows allocated to the holders of RMBS where either the issuer of such RMBS is liable for damages or is unable to enforce payment by the borrower.

In most but not all cases, the amount recoverable against a purchaser or assignee under such assignee liability provisions is limited to amounts previously paid and still owed by the borrower. Moreover, sellers of residential mortgage loans to an issuer of RMBS typically represent that the loans have been originated in accordance with all applicable laws and in the event such representation is breached, the seller typically must repurchase the offending loan. Notwithstanding these protections, an issuer of RMBS may be exposed to an unquantifiable amount of potential assignee liability because, first, the amount of potential assignee liability under certain predatory lending laws is unclear and has yet to be litigated, and, second, in the event a predatory lending law does not prohibit class action lawsuits, it is possible that an issuer of RMBS could be liable for damages for more than the original principal amount of the offending loans held by it. In such circumstances the issuer of RMBS may be forced to seek contribution from other parties, who may no longer exist or have adequate funds available to fund such contribution.

In addition, structural and legal risks of RMBS include the possibility that, in a bankruptcy or similar proceeding involving the originator or the servicer (often the same entity or affiliates), the assets of the issuer could be treated as never having been truly sold by the originator to the issuer and could be substantively consolidated with those of the originator, or the transfer of such assets to the issuer could be voided as a fraudulent transfer. Challenges based on such doctrines could result also in cash flow delays and losses on the related issue of RMBS.

Mortgage Loan Market Risk

. In the recent past, the residential mortgage market in the United States experienced difficulties that adversely affected the performance and market value of certain mortgages and mortgage related securities. Delinquencies and losses on residential mortgage loans (especially sub-prime and second lien mortgage loans) generally increased during this period and declines in or flattening of housing values in many housing markets were generally viewed as exacerbating such delinquencies and losses. Borrowers with adjustable rate mortgages (“ARMs”) are more sensitive to changes in interest rates, which affect their monthly mortgage payments, and may be unable to secure replacement mortgages at comparably low interest rates.

At any one time, a portfolio of RMBS may be backed by residential mortgage loans that are highly concentrated in only a few states or regions. As a result, the performance of such residential mortgage loans may be more susceptible to a downturn in the economy, including in particular industries that are highly represented in such states or regions, natural calamities and other adverse conditions affecting such areas. The economic downturn experienced in the recent past at the national level, and the more serious economic downturn experienced in the recent past in certain geographic areas of the United States, including in particular areas of the United States where rates of delinquencies and defaults on residential mortgage loans were particularly high, is generally viewed as having contributed to the higher rates of delinquencies and defaults on the residential mortgage loans underlying RMBS during this period. There also can be no assurance that areas of the United States that mostly avoided higher rates of delinquencies and defaults on residential mortgage loans during this period would continue to do so if an economic downturn were to reoccur at the national level.

Another factor that may contribute to, and may in the future result in, higher delinquency and default rates is the increase in monthly payments on ARMs. Any increase in prevailing market interest rates, which are currently at historical lows, may result in increased payments for borrowers who have ARMs. Moreover, with respect to hybrid mortgage loans (which are mortgage loans combining fixed and adjustable rate features) after their initial fixed rate period or other adjustable-rate mortgage loans, interest-only products or products having a lower rate, and with respect to mortgage loans with a negative amortization feature which reach their negative amortization cap, borrowers may experience a substantial increase in their monthly payment even without an increase in prevailing market interest rates. Increases in payments for borrowers may result in increased rates of delinquencies and defaults on residential mortgage loans underlying the non-agency RMBS.

As a result of rising concerns about increases in delinquencies and defaults on residential mortgage loans (particularly on sub-prime and adjustable-rate mortgage loans) and as a result of increasing concerns about the financial strength of originators and servicers and their ability to perform their obligations with respect to non-agency RMBS, there may be an adverse change in the market sentiments of investors about the market values and volatility and the degree of risk of non-agency RMBS generally. Some or all of the underlying residential mortgage loans in an issue of non-agency RMBS may have balloon payments due on their respective maturity dates. Balloon residential mortgage loans involve a greater risk to a lender than fully amortizing loans, because the ability of a borrower to pay such amount will normally depend on its ability to obtain refinancing of the related mortgage loan or sell the related mortgaged property at a price sufficient to permit the borrower to make the balloon payment, which will depend on a number of factors prevailing at the time such refinancing or sale is required, including, without limitation, the strength of the local or national residential real estate markets, interest rates and general economic conditions and the financial condition of the borrower. If borrowers are unable to make such balloon payments, the related issue of non-agency RMBS may experience losses.

The Fund may acquire RMBS backed by collateral pools of mortgage loans that have been originated using underwriting standards that are less restrictive than those used in underwriting “prime mortgage loans” and “Alt-A mortgage loans.” These lower standards include mortgage loans made to borrowers having imperfect or impaired credit histories, mortgage loans where the amount of the loan at origination is 80% or more of the value of the mortgage property, mortgage loans made to borrowers with low credit scores, mortgage loans made to borrowers who have other debt that represents a large portion of their income and mortgage loans made to borrowers whose income is not required to be disclosed or verified and are commonly referred to as “sub-prime” mortgage loans. Sub-prime mortgage loans have in recent periods experienced increased rates of delinquency, foreclosure, bankruptcy and loss, and they are likely to continue to experience delinquency, foreclosure, bankruptcy and loss rates that are higher, and that may be substantially higher, than those experienced by mortgage loans underwritten in a more traditional manner. Certain categories of RMBS, such as option ARM RMBS and sub-prime RMBS, have been referred to by the financial media as “toxic assets.”

Although the United States economy has been slowly improving in recent years, the impact of the coronavirus pandemic on the United States has caused the economy to deteriorate again and led to a high incidence of missed mortgage payments, which could result in the incidence of mortgage foreclosures, especially sub-prime mortgages, beginning to increase again, which could adversely affect the value of any RMBS owned by the Fund.

Legislation and Regulation Risk

. The significance of the mortgage crisis and loan defaults in residential mortgage loan sectors led to the enactment in July 2008 of the Housing and Economic Recovery Act of 2008, a wide-ranging housing rescue bill that offers up to $300 billion in assistance to troubled homeowners and emergency assistance to FNMA and FHLMC. This bill could potentially have a material adverse effect on the Fund’s investment program as the bill, among other things, provides approximately $180 million for “pre-foreclosure” housing counseling and legal services for distressed borrowers. In 2007, U.S. Treasury then-Secretary Henry Paulson and HUD then-Secretary Alphonso Jackson and the mortgage industry worked to develop HOPE NOW, an alliance of participants in the mortgage industry intended to work with borrowers with sub-prime mortgages facing interest rate increases and increasing payments. The Congressional Research Service reports that HOPE NOW has undertaken an initiative to provide homeowners with free telephone consultations with HUD-approved credit counselors, who can help homeowners contact their lenders and credit counselors to work out a plan to avoid foreclosure. Certain borrowers may also seek relief through the “FHA Secure” refinancing option that gives homeowners with non-FHA ARMs, current or delinquent and regardless of reset status, the ability to refinance into a FHA-insured mortgage. The Helping Families Save Their Homes Act of 2009, which was enacted on May 20, 2009, provides a safe harbor for servicers entering into “qualified loss mitigation plans” with respect to residential mortgages originated before the act was enacted. By protecting servicers from certain liabilities, this safe harbor may encourage loan modifications and reduce the likelihood that investors in securitizations will be paid on a timely basis or will be paid in full.

In addition, the mortgage crisis has led public advocacy groups to demand, and governmental officials and federal and state regulatory agencies to propose and consider, a variety of other “bailout” and “rescue” plans that could potentially have a material adverse effect on the Fund’s investment program. Some members of the U.S. Congress have expressed concern that the downturn in the housing market played a role in the rise of late mortgage payments and foreclosures and expressed an expectation that these conditions would lead to increased filings for bankruptcy. The terms of other proposed legislation or other plans may include, by way of example and not limitation, the following:

•

moratoriums on interest rate increases for certain mortgage loans and on foreclosure proceedings;

•

conversions of ARMs to fixed-rate mortgages (including in connection with government-backed refinancings of individual mortgage loans), with potential workouts to provide borrowers with equity stakes in their homes;

•

increased scrutiny of mortgage originations (including mortgage loans in which the Fund may own an interest through non-agency RMBS) and foreclosure proceedings;

•

additional registration and licensing requirements for mortgage brokers, lenders and others involved in the mortgage industry; and

•

greater relief to homeowners under the U.S. Bankruptcy Code or other federal or state laws, including relief to stay or delay the foreclosure of residential mortgage loans or to modify payment terms, including interest rates and repayment periods, of residential mortgage loans, over a lender’s objections, as the result of a “cramdown,” which decreases the debt’s value to as low as the collateral’s fair market value.

A significant number of loan modifications could result in a significant reduction in cash flows to the holders of the mortgage securities on an ongoing basis. These loan modification programs, as well as future legislative or regulatory actions, including amendments to the bankruptcy laws, that result in the modification of outstanding mortgage loans may adversely affect the value of, and the returns on, the assets in which the Fund may invest.

New laws, legislation or other government regulations, including those promulgated in furtherance of a “bailout” or “rescue” plan to address any potential crisis and distress in the residential mortgage loan sector, may result in a reduction of available transactional opportunities for the Fund, or an increase in the cost associated with such transactions. Any such law, legislation or regulation may adversely affect the market value of RMBS.

CMBS Risks

. CMBS are, generally, securities backed by obligations (including certificates of participation in obligations) that are principally secured by mortgages on real property or interests therein having a multifamily or commercial use, such as regional malls, other retail space, office buildings, industrial or warehouse properties, hotels, nursing homes and senior living centers. The market for CMBS developed more recently and, in terms of total outstanding principal amount of issues, is relatively small compared to the market for single-family RMBS.

CMBS are subject to particular risks, including lack of standardized terms, shorter maturities than residential mortgage loans and payment of all or substantially all of the principal only at maturity rather than regular amortization of principal. Additional risks may be presented by the type and use of a particular commercial property. Special risks are presented by hospitals, nursing homes, hospitality properties and certain other property types. Commercial property values and net operating income are subject to volatility, which may result in net operating income becoming insufficient to cover debt service on the related mortgage loan. The repayment of loans secured by income-producing properties is typically dependent upon the successful operation of the related real estate project rather than upon the liquidation value of the underlying real estate. Furthermore, the net operating

income from and value of any commercial property is subject to various risks, including changes in general or local economic conditions and/or specific industry segments; the solvency of the related tenants; declines in real estate values; declines in rental or occupancy rates; increases in interest rates, real estate tax rates and other operating expenses; changes in governmental rules, regulations and fiscal policies; acts of God; new and ongoing epidemics and pandemics of infectious diseases and other global health events; natural/environmental disasters; terrorist threats and attacks and social unrest and civil disturbances. Consequently, adverse changes in economic conditions and circumstances are more likely to have an adverse impact on MBS secured by loans on commercial properties than on those secured by loans on residential properties. In addition, commercial lending generally is viewed as exposing the lender to a greater risk of loss than one- to four- family residential lending. Commercial lending, for example, typically involves larger loans to single borrowers or groups of related borrowers than residential one- to four- family mortgage loans. In addition, the repayment of loans secured by income producing properties typically is dependent upon the successful operation of the related real estate project and the cash flow generated therefrom. The coronavirus pandemic in the United States has had a severe adverse effect on many commercial businesses, resulting in them not paying rent, which in turn will likely result in the owners of the underlying properties being impaired in their ability to make mortgage payments.

The exercise of remedies and successful realization of liquidation proceeds relating to CMBS is also highly dependent on the performance of the servicer or special servicer. In many cases, overall control over the special servicing of related underlying mortgage loans will be held by a “directing certificateholder” or a “controlling class representative,” which is appointed by the holders of the most subordinate class of CMBS in such series.

The Fund may not have the right to appoint the directing certificateholder. In connection with the servicing of the specially serviced mortgage loans, the related special servicer may, at the direction of the directing certificateholder, take actions with respect to the specially serviced mortgage loans that could adversely affect the Fund’s interests. There may be a limited number of special servicers available, particularly those that do not have conflicts of interest.

The Fund may invest in Subordinated CMBS issued or sponsored by commercial banks, savings and loan institutions, mortgage bankers, private mortgage insurance companies and other non-governmental issuers. Subordinated CMBS have no governmental guarantee and are subordinated in some manner as to the payment of principal and/or interest to the holders of more senior CMBS arising out of the same pool of mortgages.

Subordinated CMBS are often referred to as “B-Pieces.” The holders of Subordinated CMBS typically are compensated with a higher stated yield than are the holders of more senior CMBS. On the other hand, Subordinated CMBS typically subject the holder to greater risk than senior CMBS and tend to be rated in a lower rating category (frequently a substantially lower rating category) than the senior CMBS issued in respect of the same mortgage pool. Subordinated CMBS generally are likely to be more sensitive to changes in prepayment and interest rates and the market for such securities may be less liquid than is the case for traditional income securities and senior CMBS.

Credit Risk Associated With Originators and Servicers of Mortgage Loans

A number of originators and servicers of residential and commercial mortgage loans, including some of the largest originators and servicers in the residential and commercial mortgage loan market, have experienced serious financial difficulties, including some that are now or were subject to federal insolvency proceedings. These difficulties have resulted from many factors, including increased competition among originators for borrowers, decreased originations by such originators of mortgage loans and increased delinquencies and defaults on such mortgage loans, as well as from increases in claims for repurchases of mortgage loans previously sold by them under agreements that require repurchase in the event of breaches of representations regarding loan quality and characteristics. Such difficulties may affect the performance of MBS backed by mortgage loans. Furthermore, the inability of the originator to repurchase such mortgage loans in the event of loan representation breaches or the servicer to repurchase such mortgage loans upon a breach of its servicing obligations also may affect the performance of related MBS. Delinquencies and losses on, and, in some cases, claims for repurchase by the originator of, mortgage loans originated by some mortgage lenders have recently increased as a result of inadequate underwriting procedures and policies, including inadequate due diligence, failure to comply with predatory and other lending laws and, particularly in the case of any “no documentation” or “limited documentation” mortgage loans that may support non-agency RMBS, inadequate verification of income and employment history. Delinquencies and losses

on, and claims for repurchase of, mortgage loans originated by some mortgage lenders have also resulted from fraudulent activities of borrowers, lenders, appraisers, and other residential mortgage industry participants such as mortgage brokers, including misstatements of income and employment history, identity theft and overstatements of the appraised value of mortgaged properties. Many of these originators and servicers are very highly leveraged. These difficulties may also increase the chances that these entities may default on their warehousing or other credit lines or become insolvent or bankrupt and thereby increase the likelihood that repurchase obligations will not be fulfilled and the potential for loss to holders of non-agency MBS and subordinated security holders.

The servicers of non-agency MBS are often the same entities as, or affiliates of, the originators of these mortgage loans. Accordingly, the financial risks relating to originators of MBS described immediately above also may affect the servicing of MBS. In the case of such servicers, and other servicers, financial difficulties may have a negative effect on the ability of servicers to pursue collection on mortgage loans that are experiencing increased delinquencies and defaults and to maximize recoveries on sale of underlying properties following foreclosure. In recent years, a number of lenders specializing in residential mortgages have sought bankruptcy protection, shut down or been refused further financings from their lenders.

MBS typically provide that the servicer is required to make advances in respect of delinquent mortgage loans. However, servicers experiencing financial difficulties may not be able to perform these obligations or obligations that they may have to other parties of transactions involving these securities. Like originators, these entities are typically very highly leveraged. Such difficulties may cause servicers to default under their financing arrangements. In certain cases, such entities may be forced to seek bankruptcy protection. Due to the application of the provisions of bankruptcy law, servicers who have sought bankruptcy protection may not be required to advance such amounts. Even if a servicer were able to advance amounts in respect of delinquent mortgage loans, its obligation to make such advances may be limited to the extent that it does not expect to recover such advances due to the deteriorating credit of the delinquent mortgage loans or declining value of the related mortgaged properties. Moreover, servicers may overadvance against a particular mortgage loan or charge too many costs of resolution or foreclosure of a mortgage loan to a securitization, which could increase the potential losses to holders of MBS. In such transactions, a servicer’s obligation to make such advances may also be limited to the amount of its servicing fee. In addition, if an issue of MBS provides for interest on advances made by the servicer, in the event that foreclosure proceeds or payments by borrowers are not sufficient to cover such interest, such interest will be paid to the servicer from available collections or other mortgage income, thereby reducing distributions made on the MBS and, in the case of senior-subordinated MBS described below, first from distributions that would otherwise be made on the most subordinated MBS of such issue. Any such financial difficulties may increase the possibility of a servicer termination and the need for a transfer of servicing and any such liabilities or inability to assess such liabilities may increase the difficulties and costs in affecting such transfer and the potential loss, through the allocation of such increased cost of such transfer, to subordinated security holders.

There can be no assurance that originators and servicers of mortgage loans will not continue to experience serious financial difficulties or experience such difficulties in the future, including becoming subject to bankruptcy or insolvency proceedings, or that underwriting procedures and policies and protections against fraud will be sufficient in the future to prevent such financial difficulties or significant levels of default or delinquency on mortgage loans. Because the recent financial difficulties experienced by such originators and servicers is unprecedented and unpredictable, the past performance of the residential and commercial mortgage loans originated and serviced by them (and the corresponding performance of the related MBS) is not a reliable indicator of the future performance of such residential mortgage loans (or the related MBS).

In some cases, servicers of MBS have been the subject of legal proceedings involving the origination and/or servicing practices of such servicers. Large groups of private litigants and states’ attorneys general have brought such proceedings. Because of the large volume of mortgage loans originated and serviced by such servicers, such litigation can cause heightened financial strain on servicers. In other cases, origination and servicing practices may cause or contribute to such strain, because of representation and warranty repurchase liability arising in MBS and mortgage loan sale transactions. Any such financial strain could cause servicers to service below required standards, causing delinquencies and losses in any related MBS transaction to rise, and in extreme cases could cause the servicer to seek the protection of any applicable bankruptcy or insolvency law. In any such proceeding, it is unclear whether the fees that the servicer charges in such transactions would be sufficient to permit that servicer or a successor servicer to service the mortgage loans in such transaction adequately. If such fees had to be increased, it is likely that the most subordinated security holders in such transactions would be effectively required to pay such increased fees. Finally, these entities may be the subject of future laws designed to protect consumers from defaulting on their mortgage loans. Such laws may have an adverse effect on the cash flows paid under such MBS.

Adjustable Rate Mortgage Risk

. ARMs contain maximum and minimum rates beyond which the mortgage interest rate may not vary over the lifetime of the security. In addition, many ARMs provide for additional limitations on the maximum amount by which the mortgage interest rate may adjust for any single adjustment period. Alternatively, certain ARMs contain limitations on changes in the required monthly payment. In the event that a monthly payment is not sufficient to pay the interest accruing on an ARM, any excess interest is added to the principal balance of the mortgage loan, which is repaid through future monthly payments. If the monthly payment for such an instrument exceeds the sum of the interest accrued at the applicable mortgage interest rate and the principal payment required at such point to amortize the outstanding principal balance over the remaining term of the loan, the excess is used to reduce the then-outstanding principal balance of the ARM.

In addition, certain ARMs may provide for an initial fixed, below-market or “teaser” interest rate. During this initial fixed rate period, the payment due from the related mortgagor may be less than that of a traditional loan. However, after the “teaser” rate expires, the monthly payment required to be made by the mortgagor may increase dramatically when the interest rate on the mortgage loan adjusts. This increased burden on the mortgagor may increase the risk of delinquency or default on the mortgage loan and in turn, losses on the MBS into which that loan has been bundled. This risk may be increased as increases in prevailing market interest rates, which are currently near historical lows, may result in increased payments for borrowers with ARMs.

Stripped MBS Risk

. Stripped MBS may be subject to additional risks. One type of stripped MBS pays to one class all of the interest form the mortgage assets (the “IO class”), while the other class will receive all of the principal (the “PO class”). The yield to maturity on an IO class is extremely sensitive to the rate of principal payments (including prepayments) on the underlying mortgage assets and a rapid rate of principal payments may have a material adverse effect on the Fund’s yield to maturity from these securities. If the assets underlying the IO class experience greater than anticipated prepayments of principal, the Fund may fail to recoup fully, or at all, its initial investment in these securities. Conversely, PO class securities tend to decline in value if prepayments are slower than anticipated.

CMO Risk

. There are certain risks associated specifically with CMOs. CMOs are debt obligations collateralized by mortgage loans or mortgage pass-through securities. The average life of a CMO is determined using mathematical models that incorporate prepayment assumptions and other factors that involve estimates of future economic and market conditions. Actual future results may vary from these estimates, particularly during periods of extreme market volatility. Further, under certain market conditions, such as those that occurred during the recent downturn in the mortgage markets, the weighted average life of certain CMOs may not accurately reflect the price volatility of such securities. For example, in periods of supply and demand imbalances in the market for such securities and/or in periods of sharp interest rate movements, the prices of CMOs may fluctuate to a greater extent than would be expected from interest rate movements alone. CMOs issued by private entities are not obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities and are not guaranteed by any government agency, although the securities underlying a CMO may be subject to a guarantee. Therefore, if the collateral securing the CMO, as well as any third party credit support or guarantees, is insufficient to make payments when due, the holder could sustain a loss.

Inverse floating rate CMOs are typically more volatile than fixed or floating rate tranches of CMOs. Many inverse floating rate CMOs have coupons that move inversely to a multiple of an index. The effect of the coupon varying inversely to a multiple of an applicable index creates a leverage factor. Inverse floaters based on multiples of a stated index are designed to be highly sensitive to changes in interest rates and can subject the holders thereof to extreme reductions of yield and loss of principal. The market for inverse floating rate CMOs with highly leveraged characteristics at times may be very thin. The Fund’s ability to dispose of its positions in such securities will depend on the degree of liquidity in the markets for such securities. It is impossible to predict the amount of trading interest that may exist in such securities, and therefore the future degree of liquidity.

The Fund may also invest in REMICs, which are CMOs that qualify for special tax treatment under the Code and invest in certain mortgages principally secured by interests in real property and other permitted investments.

Additional Risks of Mortgage Related Securities

. Additional risks associated with investments in MBS

include

Interest Rate Risk

. In addition to the interest rate risks described above, certain MBS may be subject to additional risks as the rate of interest payable on certain MBS may be set or effectively capped at the weighted average net coupon of the underlying mortgage loans themselves, often referred to as an “available funds cap.” As a result of this cap, the return to the holder of such MBS is dependent on the relative timing and rate of delinquencies and prepayments of mortgage loans bearing a higher rate of interest. In general, early prepayments will have a greater negative impact on the yield to the holder of such MBS.

Structural Risk

. Because MBS generally are ownership or participation interests in pools of mortgage loans secured by a pool of properties underlying the mortgage loan pool, the MBS are entitled to payments provided for in the underlying agreement only when and if funds are generated by the underlying mortgage loan pool. This likelihood of the return of interest and principal may be assessed as a credit matter. However, the holders of MBS do not have the legal status of secured creditors, and cannot accelerate a claim for payment on their securities, or force a sale of the mortgage loan pool in the event that insufficient funds exist to pay such amounts on any date designated for such payment. The holders of MBS do not typically have any right to remove a servicer solely as a result of a failure of the mortgage pool to perform as expected.

Subordination Risk

. MBS may be subordinated to one or more other senior classes of securities of the same series for purposes of, among other things, offsetting losses and other shortfalls with respect to the related underlying mortgage loans. For example, in the case of certain MBS, no distributions of principal will generally be made with respect to any class until the aggregate principal balances of the corresponding senior classes of securities have been reduced to zero. As a result, MBS may be more sensitive to risk of loss, writedowns, the non-fulfillment of repurchase obligations, overadvancing on a pool of loans and the costs of transferring servicing than senior classes of securities.

Prepayment, Extension and Redemption Risks

MBS may reflect an interest in monthly payments made by the borrowers who receive the underlying mortgage loans. Although the underlying mortgage loans are for specified periods of time, such as 20 or 30 years, the borrowers can, and historically have paid them off sooner. When a prepayment happens, a portion of the MBS which represents an interest in the underlying mortgage loan will be prepaid. A borrower is more likely to prepay a mortgage which bears a relatively high rate of interest. This means that in times of declining interest rates, a portion of the Fund’s higher yielding securities are likely to be redeemed and the Fund will probably be unable to replace them with securities having as great a yield. In addition to reductions in the level of market interest rates and the prepayment provisions of the mortgage loans, repayments on the residential mortgage loans underlying an issue of RMBS may also be affected by a variety of economic, geographic and other factors, including the size difference between the interest rates on the underlying residential mortgage loans (giving consideration to the cost of refinancing) and prevailing mortgage rates and the availability of refinancing. Prepayments can result in lower yields to shareholders. The increased likelihood of prepayment when interest rates decline also limits market price appreciation of MBS. This is known as prepayment risk.

Except in the case of certain types of RMBS, the mortgage loans underlying RMBS generally do not contain prepayment penalties and a reduction in market interest rates will increase the likelihood of prepayments on the related RMBS. In the case of certain home equity loan securities and certain types of RMBS, even though the underlying mortgage loans often contain prepayment premiums, such prepayment premiums may not be sufficient to discourage borrowers from prepaying their mortgage loans in the event of a reduction in market interest rates, resulting in a reduction in the yield to maturity for holders of the related RMBS. RMBS typically contain provisions that require repurchase of mortgage loans by the originator or other seller in the event of a breach of a representation or warranty regarding loan quality and characteristics of such loan. Any repurchase of a mortgage loan as a result of a breach has the same effect on the yield received on the related issue of RMBS as a prepayment of such mortgage loan. Any increase in breaches of representations and the consequent repurchases of mortgage loans that result from inadequate underwriting procedures and policies and protections against fraud will have the same effect on the yield on the related RMBS as an increase in prepayment rates.

Risk of prepayment may be reduced for commercial real estate property loans containing significant prepayment penalties or prohibitions on principal payments for a period of time following origination.

MBS also are subject to extension risk. Extension risk is the possibility that rising interest rates may cause prepayments to occur at a slower than expected rate. This particular risk may effectively change a security which was considered short or intermediate term into a long-term security. The values of long-term securities generally fluctuate more widely in response to changes in interest rates than short or intermediate-term securities.

In addition, MBS may be subject to redemption at the option of the issuer. If a MBS held by the Fund is called for redemption, the Fund will be required to permit the issuer to redeem or “pay-off” the security, which could have an adverse effect on the Fund’s ability to achieve its investment objectives.

Spread Widening Risk

. The prices of MBS may decline substantially, for reasons that may not be attributable to any of the other risks described in this Prospectus. In particular, purchasing assets at what may appear to be “undervalued” levels is no guarantee that these assets will not be trading at even more “undervalued” levels at a time of valuation or at the time of sale. It may not be possible to predict, or to protect against, such “spread widening” risk.

Illiquidity Risk

. The liquidity of MBS varies by type of security; at certain times the Fund may encounter difficulty in disposing of such investments. Because MBS have the potential to be less liquid than other securities, the Fund may be more susceptible to illiquidity risk than funds that invest in other securities. In the past, in stressed markets, certain types of MBS suffered periods of illiquidity when disfavored by the market. Due to increased instability in the credit markets, the market for some MBS has experienced reduced liquidity and greater volatility with respect to the value of such securities, making it more difficult to value such securities.

Asset-Backed Securities Risk

. ABS involve certain risks in addition to those presented by MBS. There is the possibility that recoveries on the underlying collateral may not, in some cases, be available to support payments on these securities. Relative to MBS, ABS may provide the Fund with a less effective security interest in the underlying collateral and are more dependent on the borrower’s ability to pay. If many borrowers on the underlying loans default, losses could exceed the credit enhancement level and result in losses to investors in an ABS transaction. Finally, ABS have structure risk due to a unique characteristic known as early amortization, or early payout, risk. Built into the structure of most ABS are triggers for early payout, designed to protect investors from losses. These triggers are unique to each transaction and can include a significant rise in defaults on the underlying loans, a sharp drop in the credit enhancement level or the bankruptcy of the originator. Once early amortization begins, all incoming loan payments (after expenses are paid) are used to pay investors as quickly as possible based upon a predetermined priority of payment. As a result, proceeds that would otherwise be distributed to holders of a junior tranche may be diverted to pay down more senior tranches.

The collateral underlying ABS may constitute assets related to a wide range of industries and sectors, such as credit card and automobile receivables. Credit card receivables are generally unsecured and the debtors are entitled to the protection of a number of state and federal consumer credit laws, many of which give debtors the right to set off certain amounts owed on the credit cards, thereby reducing the balance due. Most issuers of automobile receivables permit the servicers to retain possession of the underlying obligations. If the servicer were to sell these obligations to another party, there is a risk that the purchaser would acquire an interest superior to that of the holders of the related automobile receivables. In addition, because of the large number of vehicles involved in a typical issuance and technical requirements under state laws, the trustee for the holders of the automobile receivables may not have an effective security interest in all of the obligations backing such receivables. If the economy of the United States deteriorates, defaults on securities backed by credit card, automobile and other receivables may increase, which may adversely affect the value of any ABS owned by the Fund. There is the possibility that recoveries on the underlying collateral may not, in some cases, be available to support payments on these securities. In recent years, certain automobile manufacturers have been granted access to emergency loans from the U.S. Government and have experienced bankruptcy. As a result of these events, the value of securities backed by receivables from the sale or lease of automobiles may be adversely affected.

Some ABS, particularly home equity loan transactions, are subject to interest rate risk and prepayment risk. A change in interest rates can affect the pace of payments on the underlying loans, which in turn, affects total return on the securities.

Collateralized Debt Obligation Risks

. The risks of an investment in a CDO depend largely on the type of the collateral securities and the class of the CDO in which the Fund invests. Normally, CBOs, CLOs and other CDOs are privately offered and sold, and thus are not registered under the securities laws. However, an active dealer market may exist for CDOs, allowing a CDO to qualify for Rule 144A transactions. In addition to the normal risks associated with fixed-income securities and ABS generally discussed in this Prospectus, CDOs carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the risk that the collateral may default or decline in value or be downgraded, if rated by a nationally recognized statistical rating organization; (iii) the Fund may invest in tranches of CDOs that are subordinate to other tranches; (iv) the structure and complexity of the transaction and the legal documents could lead to disputes among investors regarding the characterization of proceeds; (v) the investment return achieved by the Fund could be significantly different than those predicted by financial models; (vi) the lack of a readily available secondary market for CDOs; (vii) the risk of forced “fire sale” liquidation due to technical defaults such as coverage test failures; and (viii) the CDO’s manager may perform poorly.

REITs Risk

. To the extent that the Fund invests in real estate related investments, including REITs, it will be subject to the risks associated with owning real estate and with the real estate industry generally. These include difficulties in valuing and disposing of real estate, the possibility of declines in the value of real estate, risks related to general and local economic conditions, the possibility of adverse changes in the climate for real estate, environmental liability risks, the risk of increases in property taxes and operating expenses, possible adverse changes in zoning laws, the risk of casualty or condemnation losses, limitations on rents, the possibility of adverse changes in interest rates and in the credit markets and the possibility of borrowers paying off mortgages sooner than expected, which may lead to reinvestment of assets at lower prevailing interest rates. To the extent that the Fund invests in REITs, it will also be subject to the risk that a REIT may default on its obligations or go bankrupt. REITs are generally not taxed on income timely distributed to shareholders, provided they comply with the applicable requirements of the Code. By investing in REITs indirectly through the Fund, a shareholder will bear not only his or her proportionate share of the expenses of the Fund, but also, indirectly, similar expenses of the REITs. Mortgage REITs are pooled investment vehicles that invest the majority of their assets in real property mortgages and which generally derive income primarily from interest payments thereon. Investing in mortgage REITs involves certain risks related to investing in real property mortgages. In addition, mortgage REITs must satisfy highly technical and complex requirements in order to qualify for the favorable tax treatment accorded to REITs under the Code. No assurances can be given that a mortgage REIT in which the Fund invests will be able to continue to qualify as a REIT or that complying with the REIT requirements under the Code will not adversely affect such REIT’s ability to execute its business plan.

Many REITs focus on particular types of properties or properties which are especially suited for certain uses, and those REITs are affected by the risks which impact the users of their properties. For REITs that own healthcare facilities, for example, the physical characteristics of these properties and their operations are highly regulated, and those regulations often require capital expenditures or restrict the profits realizable from these properties. Some of these properties are also highly dependent upon Medicare and Medicaid payments, which are subject to changes in governmental budgets and policies. These properties may experience losses if their tenants receive lower Medicare or Medicaid rates.

U.S. Government Securities Risk

. U.S. Government debt securities generally involve lower levels of credit risk than other types of fixed-income securities of similar maturities, although, as a result, the yields available from U.S. Government debt securities are generally lower than the yields available from such other securities. Like other fixed-income securities, the values of U.S. Government securities change as interest rates fluctuate.

Zero-Coupon Securities Risk

. Zero coupon securities are securities that are sold at a discount to par value and do not pay interest during the life of the security. The discount approximates the total amount of interest the security will accrue and compound over the period until maturity at a rate of interest reflecting the market rate of the security at the time of issuance. Upon maturity, the holder of a zero coupon security is entitled to receive the par value of the security.

While interest payments are not made on zero coupon securities, holders of such securities are deemed to have received income (“phantom income”) annually, notwithstanding that cash may not be received currently. The effect of owning instruments that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon security, but at the same time eliminates the holder’s ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero coupon securities are more exposed to interest rate risk than shorter term zero coupon securities. These investments benefit the issuer by mitigating its need for cash to meet debt service, but also require a higher rate of return to attract investors who are willing to defer receipt of cash.

The Fund accrues income with respect to these securities for Federal income tax and accounting purposes prior to the receipt of cash payments. Zero coupon securities may be subject to greater fluctuation in value and less liquidity in the event of adverse market conditions than comparably rated securities that pay cash interest at regular intervals.

Further, to maintain its qualification for pass-through treatment under the Federal tax laws, the Fund is required to distribute income to its shareholders and, consequently, may have to dispose of other, more liquid portfolio securities under disadvantageous circumstances or may have to leverage itself by borrowing in order to generate the cash to satisfy these distributions. The required distributions may result in an increase in the Fund’s exposure to zero coupon securities.

In addition to the above-described risks, there are certain other risks related to investing in zero coupon securities. During a period of severe market conditions, the market for such securities may become even less liquid. In addition, as these securities do not pay cash interest, the Fund’s investment exposure to these securities and their risks, including credit risk, will increase during the time these securities are held in the Fund’s portfolio.

Pay-In-Kind Bonds Risks

. The Fund may invest in PIK bonds. PIK bonds are bonds that pay interest through the issuance of additional debt or equity securities. Similar to zero coupon obligations, PIK bonds also carry additional risk as holders of these types of securities realize no cash until the cash payment date unless a portion of such securities is sold and, if the issuer defaults, the Fund may obtain no return at all on its investment. The market price of PIK bonds is affected by interest rate changes to a greater extent, and therefore tends to be more volatile, than that of securities that pay interest in cash. Additionally, current federal tax law requires the holder of certain PIK bonds to accrue income with respect to these securities prior to the receipt of cash payments. To maintain its qualification as a RIC and avoid liability for federal income and excise taxes, the Fund may be required to distribute income accrued with respect to these securities and may have to dispose of portfolio securities under disadvantageous circumstances in order to generate cash to satisfy these distribution requirements.

Insolvency of Issuers of Indebtedness Risk

. Various laws enacted for the protection of creditors may apply to indebtedness in which the Fund invests. The information in this and the following paragraph is applicable with respect to U.S. issuers subject to U.S. federal bankruptcy law. Insolvency considerations may differ with respect to other issuers. If, in a lawsuit brought by an unpaid creditor or representative of creditors of an issuer of indebtedness, a court were to find that the issuer did not receive fair consideration or reasonably equivalent value for incurring the indebtedness and that, after giving effect to such indebtedness, the issuer (i) was insolvent, (ii) was engaged in a business for which the remaining assets of such issuer constituted unreasonably small capital or (iii) intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they mature, such court could determine to invalidate, in whole or in part, such indebtedness as a fraudulent conveyance, to subordinate such indebtedness to existing or future creditors of such issuer, or to recover amounts previously paid by such issuer in satisfaction of such indebtedness. The measure of insolvency for purposes of the foregoing will vary. Generally, an issuer would be considered insolvent at a particular time if the sum of its debts was then greater than all of its property at a fair valuation, or if the present fair saleable value of its assets was then less than the amount that would be required to pay its probable liabilities on its existing debts as they became absolute and

matured. There can be no assurance as to what standard a court would apply in order to determine whether the issuer was “insolvent” after giving effect to the incurrence of the indebtedness in which the Fund invested or that, regardless of the method of valuation, a court would not determine that the issuer was “insolvent” upon giving effect to such incurrence. In addition, in the event of the insolvency of an issuer of indebtedness in which the Fund invests, payments made on such indebtedness could be subject to avoidance as a “preference” if made within a certain period of time (which may be as long as one year) before insolvency.

The Fund does not anticipate that it will engage in conduct that would form the basis for a successful cause of action based upon fraudulent conveyance, preference or subordination. There can be no assurance, however, as to whether any lending institution or other party from which the Fund may acquire such indebtedness engaged in any such conduct (or any other conduct that would subject such indebtedness and the Fund to insolvency laws) and, if it did, as to whether such creditor claims could be asserted in a U.S. court (or in the courts of any other country) against the Fund.

Indebtedness consisting of obligations of non-U.S. issuers may be subject to various laws enacted in the countries of their issuance for the protection of creditors. These insolvency considerations will differ depending on the country in which each issuer is located or domiciled and may differ depending on whether the issuer is a non-sovereign or a sovereign entity.

Rights Risk

. The failure to exercise subscription rights to purchase common stock would result in the dilution of the Fund’s interest in the issuing company. The market for such rights is not well developed, and, accordingly, the Fund may not always realize full value on the sale of rights.

Municipal Securities Risks

. Municipal securities risks include the ability of the issuer to repay the obligation, the relative lack of information about certain issuers of municipal securities, and the possibility of future legislative changes which could affect the market for and value of municipal securities. These risks include:

General Obligation Bonds Risks

. The full faith, credit and taxing power of the municipality that issues a general obligation bond secures payment of interest and repayment of principal. Timely payments depend on the issuer’s credit quality, ability to raise tax revenues and ability to maintain an adequate tax base.

Revenue Bonds Risks

. 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 bonds generally, including that the underlying properties may not generate sufficient income to pay expenses and interest costs. Payments of interest and principal on revenue bonds are made only from the revenues generated by a particular facility, class of facilities or the proceeds of a special tax or other revenue source. These payments depend on the money earned by the particular facility or class of facilities, or the amount of revenues derived from another source. Such bonds are generally nonrecourse 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. Increases in interest rates payable on senior obligations may make it more difficult for issuers to meet payment obligations on subordinated bonds.

Private Activity Bonds Risks

. Municipalities and other public authorities issue private activity bonds to finance development of industrial facilities for use by a private enterprise. The private enterprise pays the principal and interest on the bond, and the issuer does not pledge its full faith, credit and taxing power for repayment. If the private enterprise defaults on its payments, the Fund may not receive any income or get its money back from the investment. These bonds may subject certain investors in the Fund to the federal alternative minimum tax.

Moral Obligation Bonds Risks

. Moral obligation bonds are generally issued by special purpose public authorities of a state or municipality. If the issuer is unable to meet its obligations, repayment of these bonds becomes a moral commitment, but not a legal obligation, of the state or municipality.

Municipal Notes Risks

. Municipal notes are shorter term municipal debt obligations. They may provide interim financing in anticipation of, and are secured by, tax collection, bond sales or revenue receipts. If there is a shortfall in the anticipated proceeds, the notes may not be fully repaid and the Fund may lose money.

Municipal Lease Obligations Risks

. In a municipal lease obligation, the issuer agrees to make payments when due on the lease obligation. The issuer will generally appropriate municipal funds for that purpose, but is not obligated to do so. Although the issuer does not pledge its unlimited taxing power for payment of the lease obligation, the lease obligation is secured by the leased property. However, if the issuer does not fulfill its payment obligation it may be difficult to sell the property and the proceeds of a sale may not cover the Fund’s loss.

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 “nonappropriation” 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 that the governmental issuer is prevented from maintaining occupancy of the lease 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 nonappropriation or foreclosure might prove difficult, time consuming and costly, and may result in a delay in recovering or the failure to fully recover ownership of the assets.

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 upon the municipal authority issuing the certificate 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

Liquidity of Investments

. Certain municipal bonds in which the Fund invests may lack an established secondary trading market or are otherwise considered illiquid. Liquidity of a security relates to the ability to easily dispose of the security and the price to be obtained and does not generally relate to the credit risk or likelihood of receipt of cash at maturity. Illiquid securities may trade at a discount from comparable, more liquid investments.

The financial markets in general, and certain segments of the municipal securities markets in particular, 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.

Because the Fund does not expect that it will invest more 50% of its assets in tax-exempt municipal securities, the Fund will not be eligible to pass tax-exempt interest through to its shareholders in the form of “exempt-interest dividends.” The amount of tax-exempt interest earned by the Fund will, however, generally increase the Fund’s earnings and profits for U.S. federal income tax purposes. Accordingly, distributions of the Fund attributable to tax-exempt interest will generally be taxable to shareholders as ordinary dividend income that is not eligible for the preferential tax rates applicable to “qualified dividend income,” even though the tax-exempt income, if earned directly by the shareholder, would not have been subject to U.S. federal income tax.

Emerging Markets Risk

. The Fund may invest in Non-U.S. Securities of issuers in so-called “emerging markets” (or lesser developed countries). Such investments are particularly speculative and entail all of the risks of investing in Non-U.S. Securities but to a heightened degree. “Emerging market” countries generally include every nation in the world except developed countries, that is, the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. Investments in the securities of issuers domiciled in countries with emerging capital markets involve certain additional risks that do not generally apply to investments in securities of issuers in more developed capital markets, such as (i) low or non-existent trading volume, resulting in a lack of liquidity and increased volatility in prices for such securities, as compared to securities of comparable issuers in

more developed capital markets; (ii) uncertain national policies and social, political and economic instability, increasing the potential for expropriation of assets, confiscatory taxation, high rates of inflation or unfavorable diplomatic developments; (iii) possible fluctuations in exchange rates, differing legal systems and the existence or possible imposition of exchange controls, custodial restrictions or other foreign or U.S. governmental laws or restrictions applicable to such investments; (iv) national policies that may limit the Fund’s investment opportunities such as restrictions on investment in issuers or industries deemed sensitive to national interests; and (v) the lack or relatively early development of legal structures governing private and foreign investments and private property.

Foreign investment in certain emerging market countries may be restricted or controlled to varying degrees. These restrictions or controls may at times limit or preclude foreign investment in certain emerging market issuers and increase the costs and expenses of the Fund. Certain emerging market countries require governmental approval prior to investments by foreign persons in a particular issuer, limit the amount of investment by foreign persons in a particular issuer, limit the investment by foreign persons only to a specific class of securities of an issuer that may have less advantageous rights than the classes available for purchase by domiciliaries of the countries and/or impose additional taxes on foreign investors.

Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging markets have far lower trading volumes and less liquidity than developed markets. Since these markets are often small, they may be more likely to suffer sharp and frequent price changes or long-term price depression because of adverse publicity, investor perceptions or the actions of a few large investors. In addition, traditional measures of investment value used in the United States, such as price to earnings ratios, may not apply to certain small markets. Also, there may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed capital markets, and such issuers may not be subject to accounting, auditing and financial reporting standards and requirements comparable to those to which U.S. companies are subject. In certain countries with emerging capital markets, reporting standards vary widely.

Many emerging markets have histories of political instability and abrupt changes in policies and these countries may lack the social, political and economic stability characteristic of more developed countries. As a result, their governments are more likely to take actions that are hostile or detrimental to private enterprise or foreign investment than those of more developed countries, including expropriation of assets, confiscatory taxation, high rates of inflation or unfavorable diplomatic developments. In the past, governments of such nations have expropriated substantial amounts of private property, and most claims of the property owners have never been fully settled. There is no assurance that such expropriations will not reoccur. In such an event, it is possible that the Fund could lose the entire value of its investments in the affected market. Some countries have pervasiveness of corruption and crime that may hinder investments. Certain emerging markets may also face other significant internal or external risks, including the risk of war, and ethnic, religious and racial conflicts. In addition, governments in many emerging market countries participate to a significant degree in their economies and securities markets, which may impair investment and economic growth. National policies that may limit the Fund’s investment opportunities include restrictions on investment in issuers or industries deemed sensitive to national interests. In such a dynamic environment, there can be no assurance that any or all of these capital markets will continue to present viable investment opportunities for the Fund.

Emerging markets may also have differing legal systems and the existence or possible imposition of exchange controls, custodial restrictions or other foreign or U.S. governmental laws or restrictions applicable to such investments. Sometimes, they may lack or be in the relatively early development of legal structures governing private and foreign investments and private property. In addition to withholding taxes on investment income, some countries with emerging markets may impose differential capital gains taxes on foreign investors.

Practices in relation to settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because the Fund will need to use brokers and counterparties that are less well capitalized, and custody and registration of assets in some countries may be unreliable. The possibility of fraud, negligence, undue influence being exerted by the issuer or refusal to recognize ownership exists in some emerging markets, and, along with other factors, could result in ownership registration being completely lost. The Fund would absorb any loss resulting from such registration problems and may have no successful claim for compensation. In addition, communications between the United States and emerging market countries may be unreliable, increasing the risk of delayed settlements or losses of security certificates.

Foreign Currency Risk

. Because the Fund may invest in securities denominated or quoted in currencies other than the U.S. dollar, changes in foreign currency exchange rates may affect the value of securities held by the Fund and the unrealized appreciation or depreciation of investments. Currencies of certain countries may be volatile and therefore may affect the value of securities denominated in such currencies, which means that the Fund’s NAV could decline as a result of changes in the exchange rates between foreign currencies and the U.S. dollar. The Advisors may, but are not required to, elect for the Fund to seek to protect itself from changes in currency exchange rates through hedging transactions depending on market conditions. In addition, certain countries, particularly emerging market countries, may impose foreign currency exchange controls or other restrictions on the transferability, repatriation or convertibility of currency.

Sovereign Governmental and Supranational Debt Risk

. Investments in sovereign debt involve special risks. Foreign governmental issuers of debt or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay principal or pay interest when due. In the event of default, there may be limited or no legal recourse in that, generally, remedies for defaults must be pursued in the courts of the defaulting party. Political conditions, especially a sovereign entity’s willingness to meet the terms of its debt obligations, are of considerable significance. The ability of a foreign sovereign issuer, especially an emerging market country, to make timely payments on its debt obligations will also be strongly influenced by the sovereign issuer’s balance of payments, including export performance, its access to international credit facilities and investments, fluctuations of interest rates and the extent of its foreign reserves. The cost of servicing external debt will also generally be adversely affected by rising international interest rates, as many external debt obligations bear interest at rates which are adjusted based upon international interest rates. Also, there can be no assurances that the holders of commercial bank loans to the same sovereign entity may not contest payments to the holders of sovereign debt in the event of default under commercial bank loan agreements. In addition, there is no bankruptcy proceeding with respect to sovereign debt on which a sovereign has defaulted and the Fund may be unable to collect all or any part of its investment in a particular issue. Foreign investment in certain sovereign debt is restricted or controlled to varying degrees, including requiring governmental approval for the repatriation of income, capital or proceeds of sales by foreign investors. These restrictions or controls may at times limit or preclude foreign investment in certain sovereign debt and increase the costs and expenses of the Fund.

LIBOR Risk

. The Fund may be exposed to financial instruments that are tied to LIBOR to determine payment obligations, financing terms, hedging strategies or investment value. The Fund’s investments may pay interest at floating rates based on LIBOR or may be subject to interest caps or floors based on LIBOR. The Fund may also obtain financing at floating rates based on LIBOR. Derivative instruments utilized by the Fund may also reference LIBOR.

The United Kingdom’s Financial Conduct Authority announced a phase out of LIBOR such that after June 30, 2023, the overnight, 1-month, 3-month, 6-month and 12-month U.S. dollar LIBOR settings will cease to be published or will no longer be representative. All other LIBOR settings and certain other interbank offered rates, such as the Euro Overnight Index Average (“EONIA”), ceased to be published or representative after December 31, 2021. The Fund may have investments linked to other interbank offered rates that may also cease to be published in the future. Various financial industry groups have been planning for the transition away from LIBOR, but there remain challenges to converting certain securities and transactions to a new reference rate (e.g., the Secured Overnight Financing Rate (“SOFR”), which is intended to replace the U.S. dollar LIBOR).

Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. The transition process might lead to increased volatility and illiquidity in markets for, and reduce the effectiveness of new hedges placed against, instruments whose terms currently include LIBOR. While some existing LIBOR-based instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate-setting methodology, there may be significant uncertainty regarding the effectiveness of any such alternative methodologies to replicate LIBOR. Not all existing LIBOR-based instruments may have alternative rate-setting provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. Global regulators have advised market participants to cease entering into new contracts using LIBOR as a reference rate, and it is possible that investments in LIBOR-based instruments could invite regulatory scrutiny. In addition, a liquid market for newly issued instruments that use a reference rate other than LIBOR still may be developing. There may also be challenges for the Fund to enter into hedging transactions against such newly issued instruments until a market for such hedging transactions develops. All of the aforementioned may adversely affect the Fund’s performance or NAV.

Event Risk

. Event risk is the risk that corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company’s securities may decline significantly.

Inverse Floater and Related Securities Risk

. Investments in inverse floaters, residual interest tender option bonds and similar instruments expose the Fund to the same risks as investments in fixed-income securities and derivatives, as well as other risks, including those associated with leverage and increased volatility. An investment in these securities typically will involve greater risk than an investment in a fixed rate security. Distributions on inverse floaters, residual interest tender option bonds and similar instruments will typically bear an inverse relationship to short term interest rates and typically will be reduced or, potentially, eliminated as interest rates rise. Inverse floaters, residual interest tender option bonds and similar instruments will underperform the market for fixed rate securities in a rising interest rate environment. Inverse floaters may be considered to be leveraged to the extent that their interest rates vary by a magnitude that exceeds the magnitude of the change in a reference rate of interest (typically a short term interest rate). The leverage inherent in inverse floaters is associated with greater volatility in their market values. Investments in inverse floaters, residual interest tender option bonds and similar instruments that have fixed-income securities underlying them will expose the Fund to the risks associated with those fixed-income securities and the values of those investments may be especially sensitive to changes in prepayment rates on the underlying fixed-income securities.

Inflation-Indexed Bonds Risk

. Inflation-indexed securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the value of an inflation-indexed security, including TIPs, tends to decrease when real interest rates increase and can increase when real interest rates decrease. Thus generally, during periods of rising inflation, the value of inflation-indexed securities will tend to increase and during periods of deflation, their value will tend to decrease. Interest payments on inflation-indexed securities are unpredictable and will fluctuate as the principal and interest are adjusted for inflation. There can be no assurance that the inflation index used (e.g., the Consumer Price Index for All Urban Consumers) will accurately measure the real rate of inflation in the prices of goods and services. Any increase in the principal amount of an inflation-indexed debt security will be considered taxable ordinary income, even though the Fund will not receive the principal until maturity. In order to receive the special treatment accorded to RICs and their shareholders under the Code and to avoid U.S. federal income and/or excise taxes at the Fund level, the Fund may be required to distribute this income to shareholders in the tax year in which the income is recognized (without a corresponding receipt of cash). Therefore, the Fund may be required to pay out as an income distribution in any such tax year an amount greater than the total amount of cash income the Fund actually received and to sell portfolio securities, including at potentially disadvantageous times or prices, to obtain cash needed for these income distributions.

Two structures are common. The U.S. Treasury and some other issuers use a structure that accrues inflation into the principal value of the bond. Most other issues pay out the Consumer Price Index (“CPI”) accruals as part of a semi-annual coupon.

Inflation-indexed securities issued by the U.S. Treasury have maturities of five, ten or thirty years, although it is possible that securities with other maturities will be issued in the future. The U.S. Treasury securities pay interest on a semi-annual basis, equal to a fixed percentage of the inflation-adjusted principal amount. For example, if the Fund purchased an inflation-indexed bond with a par value of $1,000 and a 3% real rate of return coupon (payable 1.5% semi-annually), and inflation over the first six months was 1%, the mid-year par value of the bond would be $1,010 and the first semi-annual interest payment would be $15.15 ($1,010 times 1.5%). If inflation during the second half of the year resulted in the whole year’s inflation equaling 3%, the end-of-year par value of the bond would be $1,030 and the second semi-annual interest payment would be $15.45 ($1,030 times 1.5%).

If the periodic adjustment rate measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and, consequently, the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds, even during a period of deflation. However, the current market value of the bonds is not guaranteed, and will fluctuate. The Fund may also invest in other inflation related bonds that may or may not provide a similar guarantee. If a guarantee of principal is not provided, the adjusted principal value of the bond repaid at maturity may be less than the original principal. In addition, if the Fund purchases inflation-indexed bonds offered by foreign issuers, the rate of inflation measured by the foreign inflation index may not be correlated to the rate of inflation in the United States.

The value of inflation-indexed bonds is expected to change in response to changes in real interest rates. Real interest rates, in turn, are tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if inflation were to rise at a faster rate than nominal interest rates, real interest rates might decline, leading to an increase in value of inflation-indexed bonds. In contrast, if nominal interest rates increased at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-indexed bonds. There can be no assurance, however, that the value of inflation-indexed bonds will be directly correlated to changes in interest rates.

In general, the measure used to determine the periodic adjustment of U.S. inflation-indexed bonds is the Consumer Price Index for Urban Consumers (“CPI-U”), which is calculated monthly by the U.S. Bureau of Labor Statistics. The CPI-U is a measurement of changes in the cost of living, made up of components such as housing, food, transportation and energy. Inflation-indexed bonds issued by a foreign government are generally adjusted to reflect a comparable inflation index, calculated by that government. There can be no assurance that the CPI-U or any foreign inflation index will accurately measure the real rate of inflation in the prices of goods and services. Moreover, there can be no assurance that the rate of inflation in a foreign country will be correlated to the rate of inflation in the United States.

Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity.

Defensive Investing Risk

. For defensive purposes, the Fund may allocate assets into cash or short-term fixed-income securities without limitation. In doing so, the Fund may succeed in avoiding losses but may otherwise fail to achieve its investment objectives. Further, the value of short-term fixed-income securities may be affected by changing interest rates and by changes in credit ratings of the investments. If the Fund holds cash uninvested it will be subject to the credit risk of the depository institution holding the cash.

Structured Investments Risk

. The Fund may invest in structured products, including structured notes, ELNs and other types of structured products. Holders of structured products bear the risks of the underlying investments, index or reference obligation and are subject to counterparty risk.

The Fund may have the right to receive payments only from the structured product and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. While certain structured products enable the investor to acquire interests in a pool of securities without the brokerage and other expenses associated with directly holding the same securities, investors in structured products generally pay their share of the structured product’s administrative and other expenses.

Although it is difficult to predict whether the prices of indices and securities underlying structured products will rise or fall, these prices (and, therefore, the prices of structured products) will be influenced by the same types of political and economic events that affect issuers of securities and capital markets generally. If the issuer of a structured product uses shorter term financing to purchase longer term securities, the issuer may be forced to sell its securities at below market prices if it experiences difficulty in obtaining such financing, which may adversely affect the value of the structured products owned by the Fund.

Structured Notes Risk

. Investments in structured notes involve risks, including credit risk and market risk. Where the Fund’s investments in structured notes are based upon the movement of one or more factors, including currency exchange rates, interest rates, referenced bonds and stock indices, depending on the factor used and the use of multipliers or deflators, changes in interest rates and movement of the factor may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured note to be reduced to zero and any further changes in the reference instrument may then reduce the principal amount payable on maturity. Structured notes may be less liquid than other types of securities and more volatile than the reference instrument or security underlying the note.

Event-Linked Securities Risk

. Event-linked securities are a form of derivative issued by insurance companies and insurance-related special purpose vehicles that apply securitization techniques to catastrophic property and casualty damages. Unlike other insurable low-severity, high-probability events, the insurance risk of which can be diversified by writing large numbers of similar policies, the holders of a typical event-linked securities are exposed to the risks from high-severity, low-probability events such as that posed by major earthquakes or hurricanes. If a catastrophe occurs that “triggers” the event-linked security, investors in such security may lose some or all of the capital invested. In the case of an event, the funds are paid to the bond sponsor—an insurer, reinsurer or corporation—to cover losses. In return, the bond sponsors pay interest to investors for this catastrophe protection. Event-linked securities can be structured to pay-off on three types of variables—insurance-industry catastrophe loss indices, insured-specific catastrophe losses and parametric indices based on the physical characteristics of catastrophic events. Such variables are difficult to predict or model, and the risk and potential return profiles of event-linked securities may be difficult to assess. Catastrophe-related event-linked securities have been in use since the 1990s, and the securitization and risk-transfer aspects of such event-linked securities are beginning to be employed in other insurance and risk-related areas. No active trading market may exist for certain event-linked securities, which may impair the ability of the Fund to realize full value in the event of the need to liquidate such assets.

Equity-Linked Notes Risk

. ELNs are hybrid securities with characteristics of both fixed-income and equity securities. An ELN is a debt instrument, usually a bond, that pays interest based upon the performance of an underlying equity, which can be a single stock, basket of stocks or an equity index. The interest payment on an ELN may in some cases be leveraged so that, in percentage terms, it exceeds the relative performance of the market. ELNs generally are subject to the risks associated with the securities of equity issuers, default risk and counterparty risk.

Credit-Linked Notes Risk

. A credit-linked note is a derivative instrument. It is a synthetic obligation between two or more parties where the payment of principal and/or interest is based on the performance of some obligation (a reference obligation). In addition to the credit risk of the reference obligations and interest rate risk, the buyer/seller of the credit-linked note is subject to counterparty risk.

Repurchase Agreements Risk

. Subject to its investment objectives and policies, the Fund may invest in repurchase agreements for investment purposes. Repurchase agreements typically involve the acquisition by the Fund of debt securities from a selling financial institution such as a bank, savings and loan association or broker-dealer. The agreement provides that the Fund will sell the securities back to the institution at a fixed time in the future. The Fund does not bear the risk of a decline in the value of the underlying security unless the seller defaults under its repurchase obligation. In the event of the bankruptcy or other default of a seller of a repurchase agreement, the Fund could experience both delays in liquidating the underlying securities and losses, including possible decline in the value of the underlying security during the period in which the Fund seeks to enforce its rights thereto; possible lack of access to income on the underlying security during this period; and expenses of enforcing its rights. While repurchase agreements involve certain risks not associated with direct investments in debt securities, the Fund follows procedures approved by the Fund’s Board that are designed to minimize such risks. In addition, the value of the collateral underlying the repurchase agreement will be at least equal to the repurchase price, including any accrued interest earned on the repurchase agreement. In the event of a default or bankruptcy by a selling financial institution, the Fund generally will seek to liquidate such collateral. However, the exercise of the Fund’s right to liquidate such collateral could involve certain costs or delays and, to the extent that proceeds from any sale upon a default of the obligation to repurchase were less than the repurchase price, the Fund could suffer a loss.

Dollar Roll Transactions Risk

. Dollar roll transactions involve the risk that the market value of the securities the Fund is required to purchase may decline below the agreed upon repurchase price of those securities. If the broker/dealer to whom the Fund sells securities becomes insolvent, the Fund’s right to purchase or repurchase securities may be restricted. Successful use of dollar rolls may depend upon the Advisors’ ability to predict correctly interest rates and prepayments. There is no assurance that dollar rolls can be successfully employed. These transactions may involve leverage.

When-Issued, Forward Commitment and Delayed Delivery Transactions Risk

. The Fund may purchase securities on a “when-issued” basis and may purchase or sell securities on a “forward commitment” basis in order to acquire the security or to offset against anticipated changes in interest rates and prices. When such transactions are negotiated, the price, which is generally expressed in yield terms, is fixed at the time the commitment is made, but delivery and payment for the securities take place at a later date. When-issued securities and forward commitments may be sold prior to the settlement date, but the Fund will enter into when-issued and forward commitments only with the intention of actually receiving or delivering the securities, as the case may be. If the Fund disposes of the right to acquire a when-issued security prior to its acquisition or disposes of its right to deliver or receive against a forward commitment, it might incur a gain or loss.

The value of these assets will be monitored daily to ensure that their marked to market value will at all times equal or exceed the corresponding obligations of the Fund. There is always a risk that the securities may not be delivered and that the Fund may incur a loss. Settlements in the ordinary course, which may take substantially more than five business days, are not treated by the Fund as when-issued or forward commitment transactions and, accordingly, are not subject to the foregoing restrictions.

Rule 18f-4 under the Investment Company Act permits the Fund to enter into when-issued or forward-settling securities (e.g., firm and standby commitments, including TBA commitments, and dollar rolls) and non-standard settlement cycle securities notwithstanding the limitation on the issuance of senior securities in Section 18 of the Investment Company Act, provided that the Fund intends to physically settle the transaction and the transaction will settle within 35 days of its trade date (the “Delayed-Settlement Securities Provision”). If a when-issued, forward-settling or non-standard settlement cycle security does not satisfy the Delayed-Settlement Securities Provision, then it is treated as a derivatives transaction under Rule 18f-4. See “Additional Risk Factors—Risk Factors in Strategic Transactions and Derivatives—Rule 18f-4 Under the Investment Company Act” below.

Securities Lending Risk

. The Fund may lend securities to financial institutions. Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees the Fund has agreed to pay a borrower), foreign exchange risk (i.e., the risk of a shortfall at default when a cash collateral investment is denominated in a currency other than the currency of the assets being loaned due to movements in foreign exchange rates), and credit, legal, counterparty and market risks. If a securities lending counterparty were to default, the Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return the Fund’s securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This event could trigger adverse tax consequences for the Fund. The Fund could lose money if its short-term investment of the collateral declines in value over the period of the loan. Substitute payments for dividends received by the Fund for securities loaned out by the Fund will generally not be considered qualified dividend income. The securities lending agent will take the tax effects on shareholders of this difference into account in connection with the Fund’s securities lending program. Substitute payments received on tax-exempt securities loaned out will not be tax-exempt income.

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. Inflation rates may change frequently and drastically as a result of various factors, including unexpected shifts in the domestic or global economy. As inflation increases, the real value of the common shares and distributions on those shares can decline. In addition, during any periods of rising inflation, interest rates on any borrowings by the Fund would likely increase, which would tend to further reduce returns to the holders of common shares.

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 their 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.

Risk Associated with Recent Market Events

. While interest rates have been historically low in recent years in the United States and abroad, inflation rates have recently risen significantly and the Federal Reserve and other central banks have recently begun raising interest rates to address inflation which, among other factors, has led to markets to experiencing high volatility. A significant increase in interest rates may cause a further decline in the market for equity securities and could lead to a recession. Further, regulators have expressed concern that rate increases may contribute to price volatility. The impact of inflation and the recent actions of the Federal Reserve have led to market volatility and may negatively affect the value of debt instruments held by the Fund and result in a negative impact on the Fund’s performance. See “Risks—Inflation Risk.”

In addition, the current contentious domestic political environment, as well as political and diplomatic events in the United States and abroad, such as presidential elections in the United States or the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, has in the past resulted, and may in the future result, in adverse consequences (including a government shutdown) to the U.S. regulatory landscape, the general market environment and/or investment sentiment, which could negatively impact the Fund’s investments and operations. Such adverse consequences may affect investor and/or consumer confidence and may adversely impact financial markets and the broader economy, potentially to a significant degree. In recent years, some countries, including the United States, have adopted and/or are considering the adoption of more protectionist trade policies. A rise in protectionist trade policies, and the possibility of changes to some international trade agreements, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, geopolitical and other risks, including environmental and public health, may add to instability in world economies and markets generally. Economies and financial markets throughout the world are becoming increasingly interconnected. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic, political and/or financial difficulties, the value and liquidity of the Fund’s investments may be negatively affected by such events.

An outbreak of an infectious coronavirus (COVID-19) that was first detected in December 2019 developed into a global pandemic that has resulted in numerous disruptions in the market and has had significant economic impact leaving general concern and uncertainty. Although vaccines have been developed and approved for use by various governments, the duration of the pandemic and its effects cannot be predicted with certainty. The impact of this coronavirus, and other epidemics and pandemics that may arise in the future, could affect the economies of many nations, individual companies and the market in general ways that cannot necessarily be foreseen at the present time.

EMU and Redenomination Risk

. As the European debt crisis progressed, the possibility of one or more Eurozone countries exiting the EMU, or even the collapse of the Euro as a common currency, arose, creating significant volatility at times in currency and financial markets generally. The effects of the collapse of the Euro, or of the exit of one or more countries from the EMU, on the U.S. and global economy and securities markets are impossible to predict and any such events could have a significant adverse impact on the value and risk profile of the Fund’s portfolio. Any partial or complete dissolution of the EMU could have significant adverse effects on currency and financial markets, and on the values of the Fund’s portfolio investments. If one or more EMU countries were to stop using the Euro as its primary currency, the Fund’s investments in such countries may be redenominated into a different or newly adopted currency. As a result, the value of those investments could decline significantly and unpredictably. In addition, securities or other investments that are redenominated may be subject to foreign currency risk, illiquidity risk and valuation risk to a greater extent than similar investments currently denominated in Euros. To the extent a currency used for redenomination purposes is not specified in respect of certain EMU-related investments, or should the Euro cease to be used entirely, the currency in which such investments are denominated may be unclear, making such investments particularly difficult to value or dispose of. The Fund may incur additional expenses to the extent it is required to seek judicial or other clarification of the denomination or value of such securities.

Market Disruption and Geopolitical Risk

The occurrence of events similar to those in recent years, such as the aftermath of the war in Iraq, instability in Afghanistan, Pakistan, Egypt, Libya, Syria, Russia, Ukraine and the Middle East, new and ongoing epidemics and pandemics of infectious diseases and other global health events, natural/environmental disasters, terrorist attacks in the United States and around the world, social and political discord, debt crises (such as the Greek crisis), sovereign debt downgrades, the Russian invasion of Ukraine, increasingly strained relations between the United States and a number of foreign countries, including historical adversaries, such as North Korea, Iran, China and Russia, and the international community generally, new and continued political unrest in various countries, such as Venezuela and Spain, the exit or potential exit of one or more countries from the European Union (“EU”) or the European Monetary Union, continued changes in the balance of political power among and within the branches of the U.S. government, among others, may result in market volatility, may have long term effects on the U.S. and worldwide financial markets, and may cause further economic uncertainties in the United States and worldwide.

Russia launched a large-scale invasion of Ukraine on February 24, 2022. The extent and duration of the military action, resulting sanctions and resulting future market disruptions, including declines in its stock markets and the value of the ruble against the U.S. dollar, in the region are impossible to predict, but could be significant. Any such disruptions caused by Russian military action or other actions (including cyberattacks and espionage) or resulting actual and threatened responses to such activity, including purchasing and financing restrictions, boycotts or changes in consumer or purchaser preferences, sanctions, tariffs or cyberattacks on the Russian government, Russian companies or Russian individuals, including politicians, could have a severe adverse effect on Russia and the European region, including significant negative impacts on the Russian economy, the European economy and the markets for certain securities and commodities, such as oil and natural gas, and may likely have collateral impacts on such sectors globally as well as other sectors. How long such military action and related events will last cannot be predicted.

China and the United States have each imposed tariffs on the other country’s products. These actions may cause 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.

On January 31, 2020, the United Kingdom (“UK”) officially withdrew from the EU (commonly known as “Brexit”). The UK and EU reached a preliminary trade agreement, which became effective on January 1, 2021, regarding the terms of their future trading relationship relating principally to the trading of goods; however, negotiations are ongoing for matters not covered by the agreement, such as the trade of financial services. Due to uncertainty of the current political environment, it is not possible to foresee the form or nature of the future trading relationship between the UK and the EU. The longer term economic, legal, political and social framework to be put in place between the UK and the EU remains unclear and the ongoing political and economic uncertainty and periods of exacerbated volatility in both the UK and in wider European markets may continue for some time. In particular, Brexit may lead to a call for similar referendums in other European jurisdictions which may cause increased economic volatility in the European and global markets and may destabilize some or all of the other EU member countries. This uncertainty may have an adverse effect on the economy generally and on the ability of the Fund and its investments to execute their respective strategies, to receive attractive returns and/or to exit certain investments at an advantageous time or price. In particular, currency volatility may mean that the returns of the Fund and its investments are adversely affected by market movements and may make it more difficult, or more expensive, if the Fund elects to execute currency hedges. Potential decline in the value of the British Pound and/or the Euro against other currencies, along with the potential downgrading of the UK’s sovereign credit rating, may also have an impact on the performance of portfolio companies or investments located in the UK or Europe. In light of the above, no definitive assessment can currently be made regarding the impact that Brexit will have on the Fund, its investments or its organization more generally.

Cybersecurity incidents affecting particular companies or industries may adversely affect the economies of particular countries, regions or parts of the world in which the Fund invests.

The occurrence of any of these above events could have a significant adverse impact on the value and risk profile of the Fund’s portfolio. The Fund does not know how long the securities markets may be affected by similar events and cannot predict the effects of similar events in the future on the U.S. economy and securities markets. There can be no assurance that similar events and other market disruptions will not have other material and adverse implications.

Regulation and Government Intervention Risk

Federal, state, and other governments, their regulatory agencies or self-regulatory organizations may take actions that affect the regulation of the issuers in which the Fund invests in ways that are unforeseeable. Legislation or regulation may also change the way in which the Fund is regulated. Such legislation or regulation could limit or preclude the Fund’s ability to achieve its investment objectives.

In light of popular, political and judicial focus on finance related consumer protection, financial institution practices are also subject to greater scrutiny and criticism generally. In the case of transactions between financial institutions and the general public, there may be a greater tendency toward strict interpretation of terms and legal rights in favor of the consuming public, particularly where there is a real or perceived disparity in risk allocation and/or where consumers are perceived as not having had an opportunity to exercise informed consent to the transaction. In the event of conflicting interests between retail investors holding common shares of a closed-end investment company such as the Fund and a large financial institution, a court may similarly seek to strictly interpret terms and legal rights in favor of retail investors.

The Fund may be affected by governmental action in ways that are not foreseeable, and there is a possibility that such actions could have a significant adverse effect on the Fund and its ability to achieve its investment objectives.

Investment Company Act Regulations

. The Fund is a registered closed-end management investment company and as such is subject to regulations under the Investment Company Act. Generally speaking, any contract or provision thereof that is made, or where performance involves a violation of the Investment Company Act or any rule or regulation thereunder is unenforceable by either party unless a court finds otherwise.

Regulation as a “Commodity Pool”

. The CFTC subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the investment adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”), or (ii) markets itself as providing investment exposure to such instruments. To the extent the Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and will not market itself as a “commodity pool” or a vehicle for trading such instruments. Accordingly, the Advisors have claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act (the “CEA”) pursuant to Rule 4.5 under the CEA. The Advisors are not, therefore, subject to registration or regulation as a “commodity pool operator” under the CEA in respect of the Fund.

Failures of Futures Commission Merchants and Clearing Organizations Risk.

The Fund is required to deposit funds to margin open positions in cleared derivative instruments (both futures and swaps) with a clearing broker registered as a “futures commission merchant” (“FCM”). The CEA requires an FCM 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 FCM’s proprietary assets. Similarly, the CEA requires each FCM to hold in a separate secure account all funds received from customers with respect to any orders for the purchase or sale of foreign futures contracts and segregate any such funds from the funds received with respect to domestic futures contracts. However, all funds and other property received by an FCM from its customers are held by an FCM on a commingled basis in an omnibus account and amounts in excess of assets posted to the clearing organization may be invested by an FCM in certain instruments permitted under the applicable regulation. There is a risk that assets deposited by the Fund with any FCM as margin for futures contracts or commodity options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s FCM. In addition, the assets of the Fund posted as margin against both swaps and futures contracts may not be fully protected in the event of the FCM’s bankruptcy.

Legal, Tax and Regulatory Risks

. Legal, tax and regulatory changes could occur that may have material adverse effects on the Fund.

To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Fund must, among other things, derive in each taxable year at least 90% of its gross income from certain prescribed sources and distribute for each taxable year at least 90% of its “investment company taxable income” (generally, ordinary income plus the excess, if any, of net short-term capital gain over net long-term capital loss). If for any taxable year the Fund does not qualify as a RIC, all of its taxable income for that year (including its net capital gain) would be subject to tax at regular corporate rates without any deduction for distributions to shareholders, and such distributions would be taxable as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits.

The Biden presidential administration has called for significant changes to U.S. fiscal, tax, trade, healthcare, immigration, foreign, and government regulatory policy. In this regard, there is significant uncertainty with respect to legislation, regulation and government policy at the federal level, as well as the state and local levels. Recent events have created a climate of heightened uncertainty and introduced new and difficult-to-quantify macroeconomic and political risks with potentially far-reaching implications. There has been a corresponding meaningful increase in the uncertainty surrounding interest rates, inflation, foreign exchange rates, trade volumes and fiscal and monetary policy. To the extent the U.S. Congress or the current presidential administration implements changes to U.S. policy, those changes may impact, among other things, the U.S. and global economy, international trade and relations, unemployment, immigration, corporate taxes, healthcare, the U.S. regulatory environment, inflation and other areas. Although the Fund cannot predict the impact, if any, of these changes to the Fund’s business, they could adversely affect the Fund’s business, financial condition, operating results and cash flows. Until the Fund knows what policy changes are made and how those changes impact the Fund’s business and the business of the Fund’s competitors over the long term, the Fund will not know if, overall, the Fund will benefit from them or be negatively affected by them.

The rules dealing with U.S. federal income taxation are constantly under review by persons involved in the legislative process and by the Internal Revenue Service and the U.S. Treasury Department. Revisions in U.S. federal tax laws and interpretations of these laws could adversely affect the tax consequences of your investment.

Potential Conflicts of Interest of the Advisor, Sub-Advisor and Others

. The investment activities of BlackRock, Inc. (“BlackRock”), the ultimate parent company of the Advisors, and its affiliates (including BlackRock and its subsidiaries (collectively, the “Affiliates”), and their respective directors, officers or employees, in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BlackRock and its Affiliates provide investment management services to other funds and discretionary managed accounts that may follow investment programs similar to that of the Fund. Subject to the requirements of the Investment Company Act, BlackRock and its Affiliates intend to engage in such activities and may receive compensation from third parties for their services. Neither BlackRock nor any Affiliate is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate may compete with the Fund for appropriate investment opportunities. The results of the Fund’s investment activities, therefore, may differ from those of an Affiliate and of other accounts managed by BlackRock or an Affiliate, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates and other accounts achieve profits on their trading for proprietary or other accounts. BlackRock has adopted policies and procedures designed to address potential conflicts of interest. For additional information about potential conflicts of interest and the way in which BlackRock addresses such conflicts, please see “Conflicts of Interest” and “Management of the Fund—Portfolio Management—Potential Material Conflicts of Interest” in the SAI.

Decision-Making Authority Risk

. Investors have no authority to make decisions or to exercise business discretion on behalf of the Fund, except as set forth in the Fund’s governing documents. The authority for all such decisions is generally delegated to the Board, which in turn, has delegated the day-to-day management of the Fund’s investment activities to the Advisors, subject to oversight by the Board.

Management Risk

. The Fund is subject to management risk because it is an actively managed investment portfolio. The Advisors and the individual portfolio managers will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results. The Fund may be subject to a relatively high level of management risk because the Fund may invest in derivative instruments, which may be highly specialized instruments that require investment techniques and risk analyses different from those associated with equities and bonds.

Valuation Risk

. The Fund is subject to valuation risk, which is the risk that one or more of the securities in which the Fund invests are valued at prices that the Fund is unable to obtain upon sale due to factors such as incomplete data, market instability or human error. The Advisors may use an independent pricing service or prices provided by dealers to value securities at their market value. Because the secondary markets for certain investments may be limited, such instruments may be difficult to value. See “Net Asset Value.” When market quotations are not available, the Advisors may price such investments pursuant to a number of methodologies, such as computer-based analytical modeling or individual security evaluations. These methodologies generate approximations of market values, and there may be significant professional disagreement about the best methodology for a particular type of financial instrument or different methodologies that might be used under different circumstances. In the absence of an actual market transaction, reliance on such methodologies is essential, but may introduce significant variances in the ultimate valuation of the Fund’s investments. Technological issues and/or errors by pricing services or other third-party service providers may also impact the Fund’s ability to value its investments and the calculation of the Fund’s NAV.

When market quotations are not readily available or are believed by the Advisor to be unreliable, the Advisor will fair value the Fund’s investments in accordance with its policies and procedures. Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Fair value pricing may require determinations that are inherently subjective and inexact about the value of a security or other asset. As a result, there can be no assurance that fair value priced assets will not result in future adjustments to the prices of securities or other assets, or that fair value pricing will reflect a price that the Fund is able to obtain upon sale, and it is possible that the fair value determined for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset. For example, the Fund’s NAV could be adversely affected if the Fund’s determinations regarding the fair value of the Fund’s investments were materially higher than the values that the Fund ultimately realizes upon the disposal of such investments. Where market quotations are not readily available, valuation may require more research than for more liquid investments. In addition, elements of judgment may play a greater role in valuation in such cases than for investments with a more active secondary market because there is less reliable objective data available. The Advisors anticipate that up to approximately 25% of the Fund’s net assets (calculated at the time of investment) may be valued using fair value. This percentage may increase over the life of the Fund and may exceed 25% of the Fund’s net assets due to a number of factors, such as when the Fund nears dissolution; outflows of cash from time to time; and changes in the valuation of these investments. The Fund prices its shares daily and therefore all assets, including assets valued at fair value, are valued daily.

The Fund’s NAV per common share is a critical component in several operational matters including computation of advisory and services fees. Consequently, variance in the valuation of the Fund’s investments will impact, positively or negatively, the fees and expenses shareholders will pay.

Reliance on the Advisor and Sub-Advisor Risk

. The Fund is dependent upon services and resources provided by the Advisors, and therefore the Advisors’ parent, BlackRock. The Advisors are not required to devote their full time to the business of the Fund and there is no guarantee or requirement that any investment professional or other employee of the Advisors will allocate a substantial portion of his or her time to the Fund. The loss of one or more individuals involved with the Advisors could have a material adverse effect on the performance or the continued operation of the Fund. For additional information on the Advisor, the Sub-Advisor and BlackRock, see “Management of the Fund—Investment Advisor and Sub-Advisor.”

Reliance on Service Providers Risk

. The Fund must rely upon the performance of service providers to perform certain functions, which may include functions that are integral to the Fund’s operations and financial performance. Failure by any service provider to carry out its obligations to the Fund in accordance with the terms of its appointment, to exercise due care and skill or to perform its obligations to the Fund at all as a result of

insolvency, bankruptcy or other causes could have a material adverse effect on the Fund’s performance and returns to shareholders. The termination of the Fund’s relationship with any service provider, or any delay in appointing a replacement for such service provider, could materially disrupt the business of the Fund and could have a material adverse effect on the Fund’s performance and returns to shareholders.

Information Technology Systems Risk

. The Fund is dependent on the Advisors for certain management services as well as back-office functions. The Advisors depend on information technology systems in order to assess investment opportunities, strategies and markets and to monitor and control risks for the Fund. It is possible that a failure of some kind which causes disruptions to these information technology systems could materially limit the Advisors’ ability to adequately assess and adjust investments, formulate strategies and provide adequate risk control. Any such information technology-related difficulty could harm the performance of the Fund. Further, failure of the back-office functions of the Advisors to process trades in a timely fashion could prejudice the investment performance of the Fund.

Cyber Security Risk

. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security and related risks. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber-attacks include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyber-attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber security failures by or breaches of the Advisors and other service providers (including, but not limited to, fund accountants, custodians, transfer agents and administrators), and the issuers of securities in which the Fund invests, have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber-attacks, 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 cyber security plans and systems put in place by service providers to the Fund and issuers in which the Fund invests. As a result, the Fund or its shareholders could be negatively impacted.

Misconduct of Employees and of Service Providers Risk

. Misconduct or misrepresentations by employees of the Advisor, the Sub-Advisor or the Fund’s service providers could cause significant losses to the Fund. Employee misconduct may include binding the Fund to transactions that exceed authorized limits or present unacceptable risks and unauthorized trading activities, concealing unsuccessful trading activities (which, in any case, may result in unknown and unmanaged risks or losses) or making misrepresentations regarding any of the foregoing. Losses could also result from actions by the Fund’s service providers, including, without limitation, failing to recognize trades and misappropriating assets. In addition, employees and service providers may improperly use or disclose confidential information, which could result in litigation or serious financial harm, including limiting the Fund’s business prospects or future marketing activities. Despite the Advisors’ due diligence efforts, misconduct and intentional misrepresentations may be undetected or not fully comprehended, thereby potentially undermining the Advisors’ due diligence efforts. As a result, no assurances can be given that the due diligence performed by the Advisors will identify or prevent any such misconduct.

Special Risks for Holders of Rights.

There is a risk that performance of the Fund may result in the common shares purchasable upon exercise of the rights being less attractive to investors at the conclusion of the subscription period. This may reduce or eliminate the value of the rights. Investors who receive rights may find that there is no market to sell rights they do not wish to exercise. If investors exercise only a portion of the rights, common shares may trade at less favorable prices than larger offerings for similar securities.

Allocation Risk

. The Fund’s ability to achieve its investment objective depends upon the Advisors’ skill in determining the Fund’s allocation of its assets and in selecting the best mix of investments. There is a risk that the Advisors’ evaluation and assumptions regarding asset classes or investments may be incorrect in view of actual market conditions.

The Fund’s allocation of its investments across various segments of the securities markets and various countries, regions, asset classes and sectors may vary significantly over time based on the Advisors’ analysis and judgment. As a result, the particular risks most relevant to an investment in the Fund, as well as the overall risk profile of the Fund’s portfolio, may vary over time. The Advisors employ an active approach to the Fund’s investment allocations, but there is no guarantee that the Advisors’ allocation strategy will produce the desired results. The percentage of the Fund’s total assets allocated to any category of investment may at any given time be significantly less than the maximum percentage permitted pursuant to the Fund’s investment policies. It is possible that the Fund will focus on an investment that performs poorly or underperforms other investments under various market conditions. The flexibility of the Fund’s investment policies and the discretion granted to the Advisors to invest the Fund’s assets across various segments, classes and geographic regions of the securities markets and in securities with various characteristics means that the Fund’s ability to achieve its investment objective may be more dependent on the success of its investment advisers than other investment companies.

Portfolio Turnover Risk

. The Fund’s annual portfolio turnover rate may vary greatly from year to year, as well as within a given year. Portfolio turnover rate is not considered a limiting factor in the execution of investment decisions for the Fund. A higher portfolio turnover rate results in correspondingly greater brokerage commissions and other transactional expenses that are borne by the Fund. High portfolio turnover may result in an increased realization of net short-term capital gains by the Fund which, when distributed to common shareholders, will be taxable as ordinary income. Additionally, in a declining market, portfolio turnover may create realized capital losses.

Anti-Takeover Provisions Risk

. The Fund’s Charter and Bylaws include provisions that could limit the ability of other entities or persons to acquire control of the Fund or convert the Fund to open-end status or to change the composition of the Board. Such provisions could limit the ability of shareholders to sell their shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Fund. See “Certain Provisions of the Charter and Bylaws.”

Effects of Leverage [Text Block]

Effects of Leverage

Assuming that leverage will represent approximately 26.45% of the Fund’s Managed Assets and that the Fund will bear expenses relating to that leverage at an average annual rate of 4.58%, the income generated by the Fund’s portfolio (net of estimated expenses) must exceed 1.21% in order to cover the expenses specifically related to the Fund’s use of leverage. Of course, these numbers are merely estimates used for illustration. Actual leverage expenses will vary frequently and may be significantly higher or lower than the rate estimated above.

The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effect of leverage on common share total return, assuming investment portfolio total returns (comprised of income and changes in the value of investments held in the Fund’s portfolio) of (10)%, (5)%, 0%, 5% and 10%. These assumed investment portfolio returns are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund. The table further reflects the use of leverage representing 26.45% of the Fund’s Managed Assets and an assumed annual cost of leverage of 4.48%.


Assumed Portfolio Total Return (Net of Expenses)	(10.00)%	(5.00)%	0%	5.00%	10.00%
Common Share Total Return	(15.24)%	(8.45)%	1.65%	5.15%	1.95%

Common share total return is composed of two elements: the common share dividends paid by the Fund (the amount of which is largely determined by the net investment income of the Fund after paying for any leverage used by the Fund) and gains or losses on the value of the securities the Fund owns. As required by SEC rules, the table assumes that the Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0% the Fund must assume that the interest it receives on its investments is entirely offset by losses in the value of those securities.

As of December 20, 2022, the NAV per common share of the Fund was $10.43 and the market price per common share was $9.38, representing a discount to NAV of (10.07)%. Common shares of the Fund have historically traded at both a premium and discount to NAV.

As of December 20, 2022, the Fund has outstanding 46,610,312 common shares.

Capital Stock, Long-Term Debt, and Other Securities [Abstract]

Capital Stock [Table Text Block]

DESCRIPTION OF CAPITAL STOCK

The Fund is authorized to issue 400,000,000 shares, par value $0.10 per share, all of which were initially classified as common shares. The Board of Directors is authorized, however, to classify and reclassify any unissued shares of capital stock into one or more additional or other classes or series as may be established from time to time by setting or changing in any one or more respects the designations, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications or terms or conditions of redemption of such shares of stock and pursuant to such classification or reclassification to increase or decrease the number of authorized shares of any existing class or series. The Fund may reclassify an amount of unissued common shares as preferred shares and at that time offer preferred shares. See “Leverage—Preferred Shares.”

Common Shares

Shareholders are entitled to share

pro rata

in the net assets of the Fund available for distribution to shareholders upon liquidation of the Fund. Shareholders are entitled to one vote for each share held. Shareholders do not have preemptive, conversion or subscription rights and the Fund’s shares of common stock are not redeemable. Shares of common stock, when issued and outstanding, will be fully paid and

non-assessable.

The Fund intends to hold annual meetings of shareholders so long as the shares of common stock are listed on a national securities exchange and such meetings are required as a condition to such listing. The Fund will send unaudited reports at least semi-annually and audited annual financial statements to all of its shareholders.

Unlike

open-end

funds,

closed-end

funds like the Fund do not continuously offer shares and do not provide daily redemptions. Rather, if a shareholder determines to buy additional common shares or sell shares already held, the shareholder may do so by trading through a broker on the NYSE or otherwise. Shares of

closed-end

investment companies frequently trade on an exchange at prices lower than NAV. Shares of

closed-end

investment companies like the Fund have during some periods traded at prices higher than NAV and during other periods have traded at prices lower than NAV. Because the market value of the common shares may be influenced by such factors as dividend levels (which are in turn affected by expenses), call protection on its portfolio securities, dividend stability, portfolio credit quality, the Fund’s NAV, relative demand for and supply of such shares in the market, general market and economic conditions, market sentiment and other factors beyond the control of the Fund, the Fund cannot assure you that its common shares will trade at a price equal to or higher than NAV in the future. The common shares are designed primarily for long-term investors and you should not purchase the common shares if you intend to sell them soon after purchase. See “Repurchase of Common Shares” below and “Repurchase of Common Shares” in the SAI.

Preferred Shares

In the event the Fund issues preferred shares, it is anticipated that such preferred shares will be issued in one or more series, with rights as determined by the Board of Directors, by action of the Board of Directors without the approval of the holders of common shares. Under the Investment Company Act, the Fund is permitted to have outstanding more than one series of preferred shares so long as no single series has a priority over another series as to the distribution of assets of the Fund or the payment of dividends. Holders of common shares will have no preemptive right to purchase any shares of preferred shares that might be issued. It is anticipated that the NAV per share of any preferred shares to be issued by the Fund will equal its original purchase price per share plus accumulated dividends per share. The Fund does not currently intend to issue preferred shares.

Under the Investment Company Act, the Fund is not permitted to issue preferred shares unless immediately after such issuance the value of the Fund’s total assets is at least 200% of the liquidation value of the outstanding preferred shares (

i.e.

, the liquidation value may not exceed 50% of the Fund’s total assets). In addition, the Fund is not permitted to declare any cash dividend or other distribution on its common shares unless, at the time of such declaration, the value of the Fund’s total assets is at least 200% of such liquidation value. If the Fund issues preferred shares, it may be subject to restrictions imposed by the guidelines of one or more rating agencies that may issue ratings for preferred shares issued by the Fund. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Fund by the Investment Company Act. It is not anticipated that these covenants or guidelines would impede the Advisors from managing the Fund’s portfolio in accordance with the Fund’s investment objectives and policies. Please see “Description of Capital Stock” in the SAI for more information.

Other Security, Title [Text Block]

RIGHTS OFFERINGS

Other Security, Description [Text Block]

RIGHTS OFFERINGS

The Fund may in the future, and at its discretion, choose to make offerings of rights to its shareholders to purchase common shares. Rights may be issued independently or together with any other offered security and may or may not be transferable by the person purchasing or receiving the rights. In connection with a rights offering to shareholders, we would distribute certificates or other documentation (

i.e.

, rights cards distributed in lieu of certificates) evidencing the rights and a Prospectus Supplement to our shareholders as of the record date that we set for determining the shareholders eligible to receive rights in such rights offering. Any such future rights offering will be made in accordance with the Investment Company Act. Under the laws of Maryland, the Board is authorized to approve rights offerings without obtaining shareholder approval.

The staff of the SEC has interpreted the Investment Company Act as not requiring shareholder approval of a transferable rights offering to purchase common shares at a price below the then current NAV so long as certain conditions are met, including: (i) a good faith determination by a fund’s board that such offering would result in a net benefit to existing shareholders; (ii) the offering fully protects shareholders’ preemptive rights and does not discriminate among shareholders (except for the possible effect of not offering fractional rights); (iii) management uses its best efforts to ensure an adequate trading market in the rights for use by shareholders who do not exercise such rights; and (iv) the ratio of a transferable rights offering does not exceed one new share for each three rights held.

The applicable Prospectus Supplement would describe the following terms of the rights in respect of which this Prospectus is being delivered:

•

the period of time the offering would remain open;

•

the underwriter or distributor, if any, of the rights and any associated underwriting fees or discounts applicable to purchases of the rights;

•

the title of such rights;

•

the exercise price for such rights (or method of calculation thereof);

•

the number of such rights issued in respect of each share;

•

the number of rights required to purchase a single share;

•

the extent to which such rights are transferable and the market on which they may be traded if they are transferable;

•

if applicable, a discussion of the material U.S. federal income tax considerations applicable to the issuance or exercise of such rights;

•

the date on which the right to exercise such rights will commence, and the date on which such right will expire (subject to any extension);

•

the extent to which such rights include an over-subscription privilege with respect to unsubscribed securities and the terms of such over-subscription privilege; and

•

termination rights we may have in connection with such rights offering.

A certain number of rights would entitle the holder of the right(s) to purchase for cash such number of common shares at such exercise price as in each case is set forth in, or be determinable as set forth in, the Prospectus Supplement relating to the rights offered thereby. Rights would be exercisable at any time up to the close of business on the expiration date for such rights set forth in the Prospectus Supplement. After the close of business on the expiration date, all unexercised rights would become void. Upon expiration of the rights offering and the receipt of payment and the rights certificate or other appropriate documentation properly executed and completed and duly executed at the corporate trust office of the rights agent, or any other office indicated in the Prospectus Supplement, the common shares purchased as a result of such exercise will be issued as soon as practicable. To the extent permissible under applicable law, we may determine to offer any unsubscribed offered securities directly to persons other than shareholders, to or through agents, underwriters or dealers or through a combination of such methods, as set forth in the applicable Prospectus Supplement.

Inflation Indexed Bonds Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Inflation-Indexed Bonds Risk

If the periodic adjustment rate measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and, consequently, the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds, even during a period of deflation. However, the current market value of the bonds is not guaranteed, and will fluctuate. The Fund may also invest in other inflation related bonds that may or may not provide a similar guarantee. If a guarantee of principal is not provided, the adjusted principal value of the bond repaid at maturity may be less than the original principal. In addition, if the Fund purchases inflation-indexed bonds offered by foreign issuers, the rate of inflation measured by the foreign inflation index may not be correlated to the rate of inflation in the United States.

The value of inflation-indexed bonds is expected to change in response to changes in real interest rates. Real interest rates, in turn, are tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if inflation were to rise at a faster rate than nominal interest rates, real interest rates might decline, leading to an increase in value of inflation-indexed bonds. In contrast, if nominal interest rates increased at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-indexed bonds. There can be no assurance, however, that the value of inflation-indexed bonds will be directly correlated to changes in interest rates.

Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity.

[1]	If the common shares are sold to or through underwriters, the Prospectus Supplement will set forth any applicable sales load and the estimated offering expenses. Fund shareholders will pay all offering expenses involved with an offering.
[2]	The Reinvestment Plan Agent’s (as defined below under “Dividend Reinvestment Plan”) fees for the handling of the reinvestment of dividends will be paid by the Fund. However, you will pay a $0.02 per share fee incurred in connection with open-market purchases, which will be deducted from the value of the dividend. You will also be charged a $2.50 sales fee and pay a $0.15 per share fee if you direct the Reinvestment Plan Agent to sell your common shares held in a dividend reinvestment account. Per share fees include any applicable brokerage commissions the Reinvestment Plan Agent is required to pay.
[3]	The Fund and the Advisor have entered into a fee waiver agreement (the “Fee Waiver Agreement”), pursuant to which the Advisor has contractually agreed to waive the management fee with respect to any portion of the Fund’s assets attributable to investments in any equity and fixed-income mutual funds and exchange-traded funds (“ETFs”) managed by the Advisor or its affiliates that have a contractual management fee, through June 30, 2024. In addition, pursuant to the Fee Waiver Agreement, the Advisor has contractually agreed to waive its management fees by the amount of investment advisory fees the Fund pays to the Advisor indirectly through its investment in money market funds managed by the Advisor or its affiliates, through June 30, 2024. The Fee Waiver Agreement may be terminated at any time, without the payment of any penalty, only by the Fund (upon the vote of a majority of the Directors who are not “interested persons” (as defined in the Investment Company Act of 1940, as amended (the “Investment Company Act”), of the Fund (the “Independent Directors”)) or a majority of the outstanding voting securities of the Fund), upon 90 days’ written notice by the Fund to the Advisor.
[4]	The Fund currently pays the Advisor a contractual management fee at an annual rate of 0.55% based on an aggregate of (i) the Fund’s average daily Net Assets and (ii) the proceeds of any outstanding debt securities or borrowings used for leverage (together, “average daily Managed Assets”). “Net Assets” means the total assets of the Fund minus the sum of the accrued liabilities. The liquidation preference of any outstanding preferred stock (other than accumulated dividends) is not considered a liability in determining the Fund’s net asset value. The Fund uses leverage in the form of a credit facility, which as of December 19, 2022 amounted to approximately 26.45% of the Fund’s Managed Assets (approximately 35.95% of the Fund’s net assets). “Managed Assets” means the total assets of the Fund minus the sum of the Fund’s accrued liabilities (other than the aggregate indebtedness constituting financial leverage). The Fund’s net assets attributable to common stock are the Fund’s Managed Assets minus the value of the Fund’s assets attributable to indebtedness constituting financial leverage. Thus, when the Fund uses leverage, its net assets attributable to common stock are less than its Managed Assets and its expenses (including the management fee) stated as a percentage of its net assets attributable to common stock are greater than they would be if stated as a percentage of its Managed Assets. This table reflects the fact that you, as a common shareholder, bear the expenses of the Fund’s use of leverage in the form of higher fees as a percentage of the Fund’s net assets attributable to common stock than if the Fund did not use leverage.
[5]	Reflects leverage, in the form of a credit facility, in an amount equal to approximately 26.45% of the Fund’s Managed Assets as of December 19, 2022. The interest expense borne by the Fund will vary over time in accordance with the level of the Fund’s use of leverage and variations in market interest rates. Interest expense is required to be treated as an expense of the Fund for accounting purposes.
[6]	Other Expenses have been restated to reflect current fees.
[7]	The Total Annual Fund Operating Expenses do not correlate to the ratios of expenses to average net assets given in the Fund’s most recent annual report, which do not include the restatement of Miscellaneous Other Expenses and Interest Expense to reflect current fees.
