The Fund

BlackRock MuniAssets Fund, Inc. is a diversified, closed-end management investment company. Throughout this Prospectus, we refer to BlackRock MuniAssets Fund, Inc. simply as the “Fund” or as “we,” “us” or “our.” See “The Fund.”

The Fund’s common shares are listed for trading on the New York Stock Exchange (“NYSE”) under the symbol “MUA.” As of [●], 2020, the net assets of the Fund were $[●], the total assets of the Fund were $[●] and the Fund had outstanding [●] common shares. The last reported sale price of the Fund’s common shares, as reported by the NYSE on [●], 2020 was $[●] per common share. The net asset value (“NAV”) of the Fund’s common shares at the close of business on [●], 2020 was $[●] per common share. See “Description of Capital Stock.” Rights issued by the Fund may also be listed on a securities exchange.

The Offering

We may offer, from time to time, in one or more offerings, up to $[●] of our common shares on terms to be determined at the time of the offering. We may also offer subscription rights to purchase our common shares. The common shares may be offered at prices and on terms to be set forth in one or more Prospectus Supplements. You should read this Prospectus and the applicable Prospectus Supplement carefully before you invest in our common shares. Our common shares may be offered directly to one or more purchasers, through agents designated from time to time by us, or to or through underwriters or dealers. The offering price per common share will not be less than the NAV per common share at the time we make the offering, exclusive of any underwriting commissions or discounts, provided that rights offerings that meet certain conditions may be offered at a price below the then current NAV. See “Rights Offerings.” The Prospectus Supplement relating to the offering will identify any agents, underwriters or dealers involved in the sale of our common shares, and will set forth any applicable purchase price, fee, commission or discount arrangement between us and our agents or underwriters, or among our underwriters, or the basis upon which such amount may be calculated. See “Plan of Distribution.” The Prospectus Supplement relating to any offering of rights will set forth the number of common shares issuable upon the exercise of each right (or number of rights) and the other terms of such rights offering. We may not sell any of our common shares through agents, underwriters or dealers without delivery of a Prospectus Supplement describing the method and terms of the particular offering of our common shares.

Use of Proceeds

The net proceeds from the issuance of common shares hereunder will be invested in accordance with our investment objective and policies as appropriate investment opportunities are identified, which is expected to be substantially completed in approximately three months from the date on which the proceeds from an offering are received by the Fund; however, the identification of appropriate investment opportunities pursuant to the Fund’s investment style or changes in market conditions could result in the Fund’s anticipated investment period extending to as long as six months. See “Use of Proceeds.”

Investment Objective and Policies

The Fund’s investment objective is to provide high current income exempt from U.S. federal income taxes by investing primarily in a portfolio of medium to lower grade or unrated municipal obligations the interest on which, in the opinion of bond counsel to the issuer, is exempt from U.S. federal income taxes. The Fund seeks to achieve its investment objective by investing at least 80% of its assets, except during temporary defensive periods, in a portfolio of obligations issued by or on behalf of states, territories and possessions of the United States and their political subdivisions, agencies or instrumentalities paying interest which, in the opinion of bond counsel to the issuer, is exempt from Federal income taxes (“Municipal Bonds”). The Fund at all times, except during temporary defensive periods, will maintain at least 65% of its assets in Municipal Bonds which are rated in any one of the medium and lower rating categories of a nationally recognized statistical rating organization or are unrated. These ratings are currently Baa (Moody’s Investor Service Inc. (“Moody’s”)) or BBB (S&P Global Ratings (“S&P”) and Fitch Ratings, Inc. (“Fitch”)) or lower. These are fundamental policies of the Fund and, therefore, may not be changed without the approval of a majority of the Fund’s outstanding voting shares as defined in the 1940 Act. The Fund may invest directly in such securities or synthetically through the use of derivatives. The Fund is not intended as, and you should not construe it to be, a complete investment program. There can be no assurance that the Fund’s investment objective will be achieved or that the Fund’s investment program will be successful. See “The Fund’s Investments—Investment Objective and Policies.”

The Fund has the authority to invest as much as 35% of its total assets in Municipal Bonds in the higher rating categories of nationally recognized statistical rating organizations (ratings of A or higher by Moody’s, S&P or Fitch or comparable unrated securities). In addition, the Fund reserves the right to temporarily invest more than 20% of its total assets in short-term municipal securities, or short-term taxable money market securities (including commercial paper, certificates of deposit and repurchase agreements) (such shorter-term obligations being referred to herein as “Temporary Investments”) for defensive purposes when, in the opinion of BlackRock Advisors, LLC (the “Advisor”), prevailing market or financial conditions warrant. The Fund does not invest more than 25% of its total assets (taken at

market value) in Municipal Bonds whose issuers are located in the same state. As used throughout this Prospectus and the Statement of Additional Information, “total assets” of the Fund means the Fund’s net assets plus the amount of any borrowings for investment purposes.

Ordinarily, the Fund does not intend to realize significant interest income that is subject to Federal income taxes. However, the Fund may invest all or a portion of its assets in certain tax-exempt securities classified as “private activity bonds” (“PABs”) (in general, bonds that benefit non-governmental entities) that may subject certain investors in the Fund to a Federal alternative minimum tax.

The Fund may invest in securities not issued by or on behalf of a state or territory or by an agency or instrumentality thereof, if the Fund receives an opinion of counsel to the issuer that such securities pay interest that is excludable from gross income for federal income tax purposes (“Non-Municipal Tax-Exempt Securities”). Non-Municipal Tax-Exempt Securities could include trust certificates, partnership interests or other instruments evidencing interest in one or more long-term Municipal Bonds. Non-Municipal Tax-Exempt Securities also may include securities issued by other investment companies that invest in Municipal Bonds, to the extent such investments are permitted by the Fund’s investment restrictions and applicable law.

The Fund ordinarily does not intend to realize significant investment income not exempt from federal income taxes. From time to time, the Fund may realize taxable capital gains.

Investments in lower rated Municipal Bonds generally provide a higher yield and are less affected by interest rate fluctuations than higher rated tax-exempt securities of similar maturity but are subject to greater overall market risk and are also subject to a greater degree of risk with respect to the ability of the issuer to meet its principal and interest obligations. See “Appendix A—Description of Municipal Bond Ratings” in the Statement of Additional Information.

The Fund seeks to reduce risk through investing in multiple issuers, credit analysis and monitoring of current developments regarding the obligor and trends in both the economy and financial markets. The Advisor will use various means to research the stability and/or potential for improvement of various municipal issuers in connection with the proposed purchase of their securities by the Funs. Evaluation of each Municipal Bond may include the analysis of financial performance, debt structure, economic factors and the administrative structure of the issuer. Additionally, the priority of liens and the overall structure of the particular issue may be factors that will determine suitability for purchase. Further investigation may be performed and may include, among other things, discussions with project management, corporate officers and industry experts as well as site inspections, area analysis, and project and financial projection

analysis. All purchases and sales also may be subject to the review of market data, economic projections and the performance of the financial markets. Certain economic indicators also may be monitored. Additionally, the Advisor will vary the average maturity of the Fund’s portfolio securities based upon its assessment of economic and market conditions.

The Fund may engage in various derivative transactions or portfolio strategies (“Strategic Transactions”) for duration management and other risk management purposes, subject to the Fund’s investment restrictions. The Fund may purchase and sell futures contracts, enter into various interest rate transactions and swap contracts (including, but not limited to, credit default swaps) and may purchase and sell exchange-listed and OTC put and call options on securities and swap contracts, financial indices and futures contracts and use other derivative instruments or management techniques. The Fund is not required to use derivatives or other portfolio strategies to seek to increase return or to seek to hedge its portfolio and may choose not to do so. The Fund cannot guarantee that any Strategic Transaction it uses will work. See “The Fund’s Investments—Strategic Transactions.”

Unless otherwise stated herein or in the SAI, the Fund’s investment policies are non-fundamental policies and may be changed by the Board without prior shareholder approval.

For a discussion of risk factors that may affect the Fund’s ability to achieve its investment objective, see “Risks.”

Leverage

The Fund currently does not intend to borrow money or issue debt securities or shares of preferred stock (“preferred shares”). The Fund is, however, permitted to borrow money or issue debt securities in an amount up to 33 1/3% of its Managed Assets (50% of its net assets), and issue preferred shares in an amount up to 50% of its Managed Assets (100% of its net assets). “Managed Assets” means the total assets of the Fund (including any assets attributable to money borrowed for investment purposes) minus the sum of the Fund’s accrued liabilities (other than money borrowed for investment purposes). Although it has no present intention to do so, the Fund reserves the right to borrow money from banks or other financial institutions, or issue debt securities or preferred shares, in the future if it believes that market conditions would be conducive to the successful implementation of a leveraging strategy through borrowing money or issuing debt securities or preferred shares. See “Leverage.”

As part of its leverage strategy, the Fund may invest in leveraged residual certificates issued by tender option bonds (“TOBs”). The residual interest municipal tender option bonds (“TOB Residuals”) in which the Fund invests pay interest or income that, in the opinion of counsel to the issuer, is exempt from regular federal income tax. The

Advisor will not conduct its own analysis of the tax status of the interest or income paid by TOB Residuals held by the Fund, but will rely on the opinion of counsel to the issuer. Although volatile, TOB Residuals typically offer the potential for yields exceeding the yields available on fixed rate municipal bonds with comparable credit quality, coupon, call provisions and maturity. The Fund may invest in TOB Residuals for the purpose of using economic leverage as a more flexible alternative to the issuance of preferred shares. See “Leverage—Tender Option Bond Transactions.”

The use of leverage is subject to numerous risks. When leverage is employed, the Fund’s NAV, the market price of the common shares and the yield to holders of common shares will be more volatile than if leverage were not used. For example, a rise in short-term interest rates, which currently are near historically low levels, generally will cause the Fund’s NAV to decline more than if the Fund had not used leverage. A reduction in the Fund’s NAV may cause a reduction in the market price of the Fund’s common shares.

The Fund cannot assure you that the use of leverage will result in a higher yield on the Fund’s common shares. Any leveraging strategy the Fund employs may not be successful. See “Risks—Leverage Risk.”

Investment Advisor

BlackRock Advisors, LLC is the Fund’s investment adviser. The Advisor receives an annual fee, payable monthly, in an amount equal to 0.55% of the average daily value of the Fund’s Net Assets. “Net Assets” means the total assets of the Fund minus the sum of its accrued liabilities. See “Management of the Fund—Investment Advisor.”

Distributions

The Fund intends to make regular monthly cash distributions of all or a portion of its net investment income to holders of the Fund’s common shares. Net capital gains, if any, will be distributed at least annually to holders of the Fund’s common shares. The Fund’s net investment income consists of all interest income accrued on portfolio assets less all expenses of the Fund. The Fund is required to allocate net capital gains and other taxable income, if any, received by the Fund among its shareholders on a pro rata basis in the year for which such capital gains and other income is realized.

a result, the distributions paid by the Fund for any particular month may be more or less than the amount actually earned by the Fund during that month. Undistributed earnings will increase the Fund’s NAV and, correspondingly, distributions from undistributed earnings and from capital, if any, will reduce the NAV.

Shareholders will automatically have all dividends and distributions reinvested in common shares of the Fund in accordance with the Fund’s dividend reinvestment plan, unless an election is made to receive cash by contacting the Reinvestment Plan Agent (as defined herein), at (800) 699-1236. See “Dividend Reinvestment Plan.

Listing

The Fund’s common shares are listed on the NYSE under the symbol “MUA.” See “Description of Capital Stock—Common Shares.”

Custodian and Transfer Agent

State Street Bank and Fund Company serves as the Fund’s custodian, and Computershare Fund Company, N.A. serves as the Fund’s transfer agent.

Administrator

State Street Bank and Fund Company serves as the Fund’s administrator and fund accountant.

Market Price of Shares

Common shares of closed-end investment companies frequently trade at prices lower than their NAV. The Fund cannot assure you that its common shares will trade at a price higher than or equal to NAV. See “Use of Proceeds.” The Fund’s common shares trade in the open market at market prices that are a function of several factors, including dividend levels (which are in turn affected by expenses), NAV, call protection for portfolio securities, portfolio credit quality, liquidity, dividend stability, relative demand for and supply of the common shares in the market, general market and economic conditions and other factors. See “Leverage,” “Risks,” “Description of Capital Stock” and “Repurchase of Common Shares.” The common shares are designed primarily for long-term investors and you should not purchase common shares of the Fund if you intend to sell them shortly after purchase.

Special Risk Considerations

An investment in common shares of the Fund involves risk. You should consider carefully the risks discussed below, which are described in more detail under “Risks” beginning on page 54 of this Prospectus.

Fixed-Income Securities Risks. Fixed-income securities in which the Fund may invest are generally subject to the following risks:

Interest Rate Risk. The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. The Fund may be subject to a greater risk of

rising interest rates due to the current period of historically low interest rates. The U.S. Federal Reserve recently increased the federal funds rate and has indicated that it may raise the federal funds rate further and tighten the monetary supply in the near future. Therefore, there is a risk that interest rates will rise, which will likely drive down prices of bonds and other fixed-income securities. The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund’s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund’s NAV. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by the Advisor. To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-related securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the NAV of the Fund to the extent that it invests in floating rate debt securities. These basic principles of bond prices also apply to U.S. Government securities. A security backed by the “full faith and credit” of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change.

The Fund’s use of leverage, as described below under “Leverage,” will tend to increase the Fund’s interest rate risk. The Fund may utilize certain strategies, including taking positions in futures or interest rate swaps, for the purpose of reducing the interest rate sensitivity of fixed-income securities held by the Fund and decreasing the Fund’s exposure to interest rate risk. The Fund is not required to hedge its exposure to interest rate risk and may choose not to do so. In addition, there is no assurance that any attempts by the Fund to reduce interest rate risk will be successful or that any hedges that the Fund may establish will perfectly correlate with movements in interest rates.

Issuer Risk. The value of fixed-income securities may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage, reduced demand for the issuer’s goods and services, historical and prospective earnings of the issuer and the value of the assets of the issuer.

when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates. To the extent the Fund invests in below investment grade securities, it will be exposed to a greater amount of credit risk than a fund that only invests in investment grade securities. See “Risks—Below Investment Grade Securities Risk.” In addition, to the extent the Fund uses credit derivatives, such use will expose it to additional risk in the event that the bonds underlying the derivatives default. The degree of credit risk depends on the issuer’s financial condition and on the terms of the securities.

Prepayment Risk. During periods of declining interest rates, borrowers may exercise their option to prepay principal earlier than scheduled. For fixed rate securities, such payments often occur during periods of declining interest rates, forcing the Fund to reinvest in lower yielding securities, resulting in a possible decline in the Fund’s income and distributions to shareholders. This is known as prepayment or “call” risk. For premium bonds (bonds acquired at prices that exceed their par or principal value) purchased by the Fund, prepayment risk may be enhanced. Below investment grade securities frequently have call features that allow the issuer to redeem the security at dates prior to its stated maturity at a specified price (typically greater than par) only if certain prescribed conditions are met (i.e., “call protection”). For premium bonds (bonds acquired at prices that exceed their par or principal value) purchased by the Fund, prepayment risk may be enhanced.

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

Duration and Maturity Risk. The Fund has no set policy regarding portfolio maturity or duration of the fixed-income securities it may hold. The Advisor may seek to adjust the portfolio’s duration or maturity based on its assessment of current and projected market conditions and all other factors that the Advisor deems relevant.

Any decisions as to the targeted duration or maturity of any particular category of investments or of the Fund’s portfolio generally will be made based on all pertinent market factors at any given time. The Fund may incur costs in seeking to adjust the portfolio’s average duration or maturity. There can be no assurance that the Advisor’s assessment of current and projected market conditions will be correct or that any strategy to adjust the portfolio’s duration or maturity will be successful at any given time. In general, the longer the duration of any fixed-income securities in the Fund’s portfolio, the more exposure the Fund will have to the interest rate risks described above. See “Risks—Fixed-Income Securities Risk—Duration and Maturity Risk.”

Nonpayment Risk. Municipal Bonds, like other debt obligations, are subject to the risk of nonpayment. The ability of issuers of municipal securities to make timely payments of interest and principal may be adversely impacted in general economic downturns and as relative governmental cost burdens are allocated and reallocated among federal, state and local governmental units. Such nonpayment would result in a reduction of income to the Fund and could result in a reduction in the value of the municipal security experiencing nonpayment and a potential decrease in the NAV of the Fund.

Spread Risk. Wider credit spreads and decreasing market values typically represent a deterioration of a debt security’s credit soundness and a perceived greater likelihood or risk of default by the issuer. See “Risks—Fixed-Income Securities Risk—Spread Risk.”

Municipal Bond Market Risk. Economic exposure to the municipal securities market involves certain risks. The Fund’s economic exposure to municipal securities includes municipal securities in the Fund’s portfolio and municipal securities to which the Fund is exposed through the ownership of TOB Residuals. The municipal market is one in which dealer firms make markets in bonds on a principal basis using their proprietary capital, and during the financial crisis of 2007-2009 these firms’ capital was severely constrained. As a result, some firms were unwilling to commit their capital to purchase and to serve as a dealer for municipal securities. Certain municipal securities may not be registered with the SEC or any state securities commission and will not be listed on any national securities exchange. The amount of public information available about the municipal securities to which the Fund is economically exposed is generally less than that for corporate equities or bonds, and the investment performance of the Fund may therefore be more dependent on the analytical abilities of the Advisor than would be a fund investing solely in stocks or taxable bonds. The secondary market for municipal securities, particularly the below investment grade securities to which the Fund may be economically exposed, also tends to be less well-developed or liquid than many other securities markets, which may adversely affect the Fund’s ability to sell such securities at attractive prices or at prices approximating those at which the Fund currently values them.

factors which are beyond the entity’s control. In addition, laws enacted in the future by Congress or state legislatures or referenda could extend the time for payment of principal and/or interest, or impose other constraints on enforcement of such obligations or on the ability of municipalities to levy taxes. Issuers of municipal securities might seek protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, holders of municipal securities could experience delays in collecting principal and interest and such holders may not, in all circumstances, be able to collect all principal and interest to which they are entitled. To enforce its rights in the event of a default in the payment of interest or repayment of principal, or both, the Fund may take possession of and manage the assets securing the issuer’s obligations on such securities, which may increase the Fund’s operating expenses. Any income derived from the Fund’s ownership or operation of such assets may not be tax-exempt or may fail to generate qualifying income for purposes of the income tests applicable to regulated investment companies.

Risk Factors and Special Considerations Relating to Municipal Bonds. The risks and special considerations involved in investment in Municipal Bonds vary with the types of instruments being acquired. Investments in Non-Municipal Tax-Exempt Securities may present similar risks, depending on the particular product. Certain instruments in which the Fund may invest may be characterized as derivative instruments. See “The Fund’s Investments—Description of Municipal Bonds” and “The Fund’s Investments—Strategic Transactions—Financial Futures Transactions and Options.”

The value of Municipal Bonds generally may be affected by uncertainties in the municipal markets as a result of legislation or litigation, including legislation or litigation that changes the taxation of Municipal Bonds or the rights of Municipal Bond holders in the event of a bankruptcy. Municipal bankruptcies are rare, and certain provisions of the U.S. Bankruptcy Code governing such bankruptcies are unclear. Further, the application of state law to Municipal Bond issuers could produce varying results among the states or among Municipal Bond issuers within a state. These uncertainties could have a significant impact on the prices of the Municipal Bonds in which the Fund invests.

Tax-Exempt Status Risk. In making investments, the Fund and the Advisor will rely on the opinion of issuers’ bond counsel and, in the case of derivative securities, sponsors’ counsel, on the tax-exempt status of interest on municipal obligations and payments under tax-exempt derivative securities. Neither the Fund nor the Advisor will independently review the bases for those tax opinions. If any of those tax opinions are ultimately determined to be incorrect or if events occur after the security is acquired that impact the security’s tax-exempt status, the Fund and its shareholders could be subject to substantial tax liabilities. An assertion by the Internal Revenue

Service that a portfolio security is not exempt from U.S. federal income tax (contrary to indications from the issuer) could affect the Fund’s and its shareholders’ income tax liability for the current or past years and could create liability for information reporting penalties. In addition, an IRS assertion of taxability may cause the Fund to be ineligible to pay exempt-interest dividends or may impair the liquidity and the fair market value of the securities.

Taxability Risk. The Fund intends to minimize the payment of taxable income to shareholders by investing in tax-exempt or municipal securities in reliance at the time of purchase on an opinion of bond counsel to the issuer that the interest paid on those securities will be excludable from gross income for U.S. federal income tax purposes. Such securities, however, may be determined to pay, or have paid, taxable income subsequent to the Fund’s acquisition of the securities. In that event, the Internal Revenue Service may demand that the Fund pay U.S. federal income taxes on the affected interest income, and, if the Fund agrees to do so, the Fund’s yield could be adversely affected. In addition, the treatment of dividends previously paid or to be paid by the Fund as “exempt interest dividends” could be adversely affected, subjecting the Fund’s shareholders to increased U.S. federal income tax liabilities. Federal tax legislation may limit the types and volume of bonds the interest on which qualifies for a federal income tax-exemption. As a result, current legislation and legislation that may be enacted in the future may affect the availability of Municipal Bonds for investment by the Fund. In addition, future laws, regulations, rulings or court decisions may cause interest on municipal securities to be subject, directly or indirectly, to U.S. federal income taxation or interest on state municipal securities to be subject to state or local income taxation, or the value of state municipal securities to be subject to state or local intangible personal property tax, or may otherwise prevent the Fund from realizing the full current benefit of the tax-exempt status of such securities. Any such change could also affect the market price of such securities, and thus the value of an investment in the Fund.

Alternative Minimum Tax Risk. The Fund expects that a portion of the interest or income it produces will be includable in alternative minimum taxable income. Exempt interest dividends also are likely to be subject to state and local income taxes. Distributions of any capital gain or other taxable income will be taxable to shareholders. The Fund may not be a suitable investment for investors subject to the federal alternative minimum tax or who would become subject to such tax by investing in the Fund. The Fund’s common shares may not be a suitable investment for investors who are subject to the federal alternative minimum tax or who would become subject to such tax by purchasing common shares. The suitability of an investment in common shares will depend upon a comparison of the after-tax yield likely to be provided from the Fund with that from comparable tax-exempt investments not subject to the alternative

minimum tax, and from comparable fully taxable investments, in light of each such investor’s tax position. Special considerations apply to corporate investors.

Insurance Risk. Insurance guarantees that interest payments on a municipal security will be made on time and that the principal will be repaid when the security matures. Insurance is expected to protect the Fund against losses caused by a municipal security issuer’s failure to make interest and principal payments. However, insurance does not protect the Fund or its shareholders against losses caused by declines in a municipal security’s value. Also, the Fund cannot be certain that any insurance company will make the payments it guarantees. Certain significant providers of insurance for municipal securities incurred significant losses as a result of exposure to sub-prime mortgages and other lower credit quality investments that experienced defaults or otherwise suffered extreme credit deterioration during the financial crisis of 2007-2009. These losses have reduced the insurers’ capital and called into question their continued ability to perform their obligations under such insurance if they are called upon to do so in the future. While an insured municipal security will typically be deemed to have the rating of its insurer, if the insurer of a municipal security suffers a downgrade in its credit rating or the market discounts the value of the insurance provided by the insurer, the rating of the underlying municipal security will be more relevant and the value of the municipal security would more closely, if not entirely, reflect such rating. The Fund may lose money on its investment if the insurance company does not make payments it guarantees. If a municipal security’s insurer fails to fulfill its obligations or loses its credit rating, the value of the security could drop.

Yield and Ratings Risk. The yields on 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 Advisor will consider such an event in determining whether the Fund should continue to hold the security. See “Risks—Yield and Ratings Risk.”

Below Investment Grade Securities Risk. The Fund may invest in securities that are rated, at the time of investment, below investment grade quality (rated Ba/BB or below, or judged to be of comparable quality by the Advisor), which are commonly referred to as “high

yield” or “junk” bonds and are regarded as predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal when due. The value of high yield, lower quality bonds is affected by the creditworthiness of the issuers of the securities and by general economic and specific industry conditions. Issuers of high yield bonds are not perceived to be as strong financially as those with higher credit ratings. These issuers are more vulnerable to financial setbacks and recession than more creditworthy issuers, which may impair their ability to make interest and principal payments. 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 secondary market for lower grade securities may be less liquid than that for 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. Because of the substantial risks associated with investments in lower grade securities, you could lose money on your investment in common shares of the Fund, both in the short-term and the long-term. 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 objective will be more dependent on the Advisor’s credit analysis than would be the case when the Fund invests in rated securities. See “Risks—Below Investment Grade Securities Risk.”

Unrated Securities Risk. Because the Fund may purchase securities that are not rated by any rating organization, the Advisor 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 objective will be more dependent on the Advisor’s credit analysis than would be the case when the Fund invests in rated securities.

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.

The Fund accrues income with respect to these securities for U.S. 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.

Variable Rate Demand Obligations Risk. Variable rate demand obligations (“VRDOs”) are floating rate securities that combine an interest in a long-term municipal bond with a right to demand payment before maturity from a bank or other financial institution. If the bank or financial institution is unable to pay, the Fund may lose money.

Indexed and Inverse Floating Rate Securities Risk. Investments in inverse floaters, TOB Residuals 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, TOB Residuals 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, TOB Residuals 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, TOB Residuals 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.

Investment and Market Discount Risk. An investment in the Fund’s common shares is subject to investment risk, including the possible loss of the entire amount that you invest. As with any stock, the price of the Fund’s common shares will fluctuate with market conditions and other factors. If shares are sold, the price received may be more or less than the original investment. Common shares are designed for long-term investors and the Fund should not be treated as a trading vehicle. Shares of closed-end management investment companies frequently trade at a discount from their NAV. This risk is separate and distinct from the risk that the Fund’s NAV could decrease as a result of its investment activities. At any point in time an investment in the Fund’s common shares may be worth less than the original amount invested, even after taking into account distributions paid by the Fund. During periods in which the Fund may use leverage, the Fund’s investment, market discount and certain other risks will be magnified.

Restricted and Illiquid Investments Risk. 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. The Fund may not be able to readily dispose of such investments at prices that approximate those at which the Fund could sell such investments if they were more widely traded and, as a result of such illiquidity, the Fund may have to sell other investments or engage in borrowing transactions if necessary to raise cash to meet its obligations. Limited liquidity can also affect the market price of investments, thereby adversely affecting the Fund’s NAV and ability to make dividend distributions. The financial markets in general, and certain segments of the mortgage-related 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 investments could be sold only at arbitrary prices and with substantial losses. Periods of such market dislocation may occur again at any time. Privately issued debt securities are often of below investment grade quality, frequently are unrated and present many of the same risks as investing in below investment grade public debt securities. See “Risks—Restricted and Illiquid Investments Risk.”

Investment Companies and ETFs Risk. Subject to the limitations set forth in the Investment Company Act and the Fund’s governing documents or as otherwise permitted by the SEC, the Fund may acquire shares in other investment companies, including exchange-traded funds (“ETFs”) or business development companies (“BDCs”), some of which may be affiliated investment companies. The market

value of the shares of other investment companies may differ from their NAV. As an investor in investment companies, including ETFs or BDCs, the Fund would bear its ratable share of that entity’s expenses, including its investment advisory and administration fees, while continuing to pay its own advisory and administration fees and other expenses (to the extent not offset by the Advisor through waivers). As a result, shareholders will be absorbing duplicate levels of fees with respect to investments in other investment companies, including ETFs or BDCs (to the extent not offset by the Advisor through waivers).

The securities of other investment companies, including ETFs or BDCs, in which the Fund may invest may be leveraged. As a result, the Fund may be indirectly exposed to leverage through an investment in such securities. An investment in securities of other investment companies, including ETFs or BDCs, that use leverage may expose the Fund to higher volatility in the market value of such securities and the possibility that the Fund’s long-term returns on such securities (and, indirectly, the long-term returns of the Fund’s common shares) will be diminished.

ETFs are generally not actively managed and may be affected by a general decline in market segments relating to its index. An ETF typically invests in securities included in, or representative of, its index regardless of their investment merits and does not attempt to take defensive positions in declining markets.

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.

Leverage Risk. The Board has authorized the Fund to use economic leverage up to 25% of its total assets. The Fund currently intends to use economic leverage approximately equal to 15% of its total assets at the time the leverage is implemented, but may use economic leverage up to 25% of its total assets under the leverage policy set by the Board without further Board or shareholder approval. The Board could in the future authorize the Fund to use additional leverage up to the maximum amount permitted under the 1940 Act or change the 25% threshold at which Board approval is required to increase leverage, in each case without further shareholder approval.

The use of leverage creates an opportunity for increased common share net investment income dividends, but also creates risks for the holders of common shares. The Fund currently leverages assets through tender option bonds transactions. See “Risks—Tender Option

Bond Risk” for details about the risks associated with the Fund’s use of TOB Residuals. The Fund cannot assure you that the use of leverage will result in a higher yield on the common shares. Any leveraging strategy the Fund employs may not be successful.

Leverage involves risks and special considerations for common shareholders, including:

•

the likelihood of greater volatility of NAV, market price and dividend rate of the common shares than a comparable portfolio without leverage;

•

the risk that fluctuations in interest rates or dividend rates on any leverage that the Fund must pay will reduce the return to the common shareholders;

•

the effect of leverage in a declining market, which is likely to cause a greater decline in the NAV of the common shares than if the Fund were not leveraged, which may result in a greater decline in the market price of the common shares;

•

leverage may increase operating costs, which may reduce total return.

The Fund currently does not intend to borrow money or issue debt securities or preferred shares, but may in the future borrow funds from banks or other financial institutions, or issue debt securities or preferred shares, as described in this Prospectus. Certain types of leverage the Fund may use may result in the Fund being subject to covenants relating to asset coverage and portfolio composition requirements. The Fund may be subject to certain restrictions on investments imposed by guidelines of one or more rating agencies, which may issue ratings for any debt securities or preferred shares issued by the Fund. The terms of any borrowings or these rating agency guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed by the Investment Company Act. The Advisor does not believe that these covenants or guidelines will impede it from managing the Fund’s portfolio in accordance with the Fund’s investment objective and policies. See “Risks—Leverage Risk.”

Tender Option Bond Risk. The Fund currently leverages its assets through the use of TOB Residuals, which are derivative interests in municipal bonds. The TOB Residuals in which the Fund may invest pay interest or income that, in the opinion of counsel to the issuer of such TOB Residuals, is exempt from regular U.S. federal income tax. No independent investigation will be made to confirm the tax-exempt status of the interest or income paid by TOB Residuals held by the Fund. There is no assurance that the Fund’s strategy of using TOB Residuals to leverage its assets will be successful.

TOB Residuals represent beneficial interests in a special purpose trust formed for the purpose of holding municipal bonds contributed by one or more funds (a “TOB Trust”). A TOB Trust typically issues two classes of beneficial interests: short-term floating rate interests (“TOB Floaters”), which are sold to third party investors, and TOB Residuals, which are generally issued to the fund(s) that transferred municipal bonds to the TOB Trust. TOB Floaters may have first priority on the cash flow from the municipal bonds held by the TOB Trust and are enhanced with a liquidity support arrangement provided by a third party bank or other financial institution (the “TOBs Liquidity Provider”) which allows holders to tender their position at par (plus accrued interest). The Fund, as a holder of TOB Residuals, is paid the residual cash flow from the TOB Trust. As result, distributions on TOB Residuals will bear an inverse relationship to short-term municipal bond interest rates. Distributions on the TOB Residuals paid to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. The amount of such reduction or increase is a function, in part, of the amount of TOB Floaters sold by the TOB Trust relative to the amount of the TOB Residuals that it sells. The greater the amount of TOB Floaters sold relative to the TOB Residuals, the more volatile the distributions on the TOB Residuals will be. Short-term interest rates are at historic lows and may be more likely to rise in the current market environment.

The municipal bonds transferred to a TOB Trust typically are high grade municipal bonds. In certain cases, when municipal bonds transferred are lower grade municipal bonds, the TOB Trust transaction includes a credit enhancement feature that provides for the timely payment of principal and interest on the bonds to the TOB Trust by a credit enhancement provider. The TOB Trust would be responsible for the payment of the credit enhancement fee and the Fund, as a TOB Residual holder, would be responsible for reimbursement of any payments of principal and interest made by the credit enhancement provider.

Any economic leverage achieved through the Fund’s investment in TOB Residuals will increase the possibility that common share long-term returns will be diminished if the cost of the TOB Floaters issued by a TOB Trust exceeds the return on the securities in the TOB Trust. If the income and gains earned on municipal securities owned by a TOB Trust that issues TOB Residuals to the Fund are greater than the payments due on the TOB Floaters issued by the TOB Trust, the Fund’s returns will be greater than if it had not invested in the TOB Residuals.

TOB Residuals have varying degrees of liquidity based, among other things, upon the liquidity of the underlying securities deposited in the TOB Trust. The market price of TOB Residuals is more volatile than the underlying municipal bonds due to leverage.

The leverage attributable to the Fund’s use of TOB Residuals may be “called away” on relatively short notice and therefore may be less permanent than more traditional forms of leverage. The TOB Trust may be collapsed without the consent of the Fund upon the occurrence of termination events, as defined in the TOB Trust agreements. Upon the occurrence of a termination event, a TOB Trust would be liquidated with the proceeds applied first to any accrued fees owed to the trustee of the TOB Trust, the remarketing agent of the TOB Floaters and the TOBs Liquidity Provider. Upon certain termination events, the holders of the TOB Floaters would be paid before the TOB Residual holders (i.e., the Fund) whereas in other termination events, the holders of TOB Floaters and the TOB Residual holders would be paid pro rata.

The Fund may invest in a TOB Trust on either a non-recourse or recourse basis. If the Fund invests in a TOB Trust on a recourse basis, it will typically enter into a reimbursement agreement with the TOBs Liquidity Provider pursuant to which the Fund is required to reimburse the TOBs Liquidity Provider the balance, if any, of the amount owed under the liquidity facility over the liquidation proceeds (the “Liquidation Shortfall”). As a result, if the Fund invests in a recourse TOB Trust, the Fund will bear the risk of loss with respect to any Liquidation Shortfall.

The use of TOB Residuals will require the Fund to earmark or segregate liquid assets in an amount equal to any TOB Floaters, plus any accrued but unpaid interest due on the TOB Floaters, issued by TOB Trusts sponsored by, or on behalf of, the Fund that are not owned by the Fund. The use of TOB Residuals may also require the Fund to earmark or segregate liquid assets in an amount equal to loans provided by the TOBs Liquidity Provider to the TOB Trust to purchase tendered TOB Floaters. While the segregated assets may be invested in liquid securities, they may not be used for other operational purposes. Consequently, the use of leverage through TOB Residuals may limit the Fund’s flexibility and may require that the Fund sell other portfolio investments to pay Fund expenses, to maintain assets in an amount sufficient to cover the Fund’s leveraged exposure or to meet other obligations at a time when it may be disadvantageous to sell such assets. Future regulatory requirements or SEC guidance may necessitate more onerous contractual or regulatory requirements, which may increase the costs or reduce the degree of potential economic benefits of TOB Trust transactions or limit the Fund’s ability to enter into or manage TOB Trust transactions.

The Fund structures and “sponsors” the TOB Trusts in which it holds TOB Residuals and has certain duties and responsibilities, which may give rise to certain additional risks including, but not limited to, compliance, securities law and operational risks.

The SEC and various federal banking and housing agencies recently adopted credit risk retention rules for securitizations (the “Risk Retention Rules”). The Risk Retention Rules would require the sponsor of a TOB Trust to retain at least 5% of the credit risk of the underlying assets supporting the TOB Trust’s municipal bonds. The Risk Retention Rules may adversely affect the Fund’s ability to engage in TOB Trust transactions or increase the costs of such transactions in certain circumstances.

TOB Trusts constitute an important component of the municipal bond market. Any modifications or changes to the rules governing TOB Trusts may adversely impact the municipal market and the Fund, including through reduced demand for and liquidity of municipal bonds and increased financing costs for municipal issuers. The ultimate impact of any potential modifications on the TOB market and the overall municipal market is not yet certain.

Please see “The Fund’s Investments—Leverage—Tender Option Bond Transactions” for additional information.

Strategic Transactions and Derivatives Risk. The Fund may engage in various Strategic Transactions for duration management and other 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 or to establish a position in the securities markets as a temporary substitute for purchasing particular securities or to enhance income or gain. Derivatives are financial contracts or instruments whose value depends on, or is derived from, the value of an underlying asset, reference rate or index (or relationship between two indices). The Fund also may use derivatives to add leverage to the portfolio and/or to hedge against increases in the Fund’s costs associated with any leverage strategy that it may employ. The use of Strategic Transactions to enhance current income may be particularly speculative.

experience a lack of liquidity, OTC non-standardized derivative transactions are generally less liquid than exchange-traded instruments. The illiquidity of the derivatives markets may be due to various factors, including congestion, disorderly markets, limitations on deliverable supplies, the participation of speculators, government regulation and intervention, and technical and operational or system failures. In addition, daily limits on price fluctuations and speculative position limits on exchanges on which the Fund may conduct its transactions in derivative instruments may prevent prompt liquidation of positions, subjecting the Fund to the potential of greater losses. Furthermore, the Fund’s ability to successfully use Strategic Transactions depends on the Advisor’s ability to predict pertinent securities prices, interest rates, currency exchange rates and other economic factors, 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. Additionally, segregated or earmarked liquid assets, amounts paid by the Fund as premiums and cash or other assets held in margin accounts with respect to Strategic Transactions are not otherwise available to the Fund for investment purposes.

Many OTC derivatives are valued on the basis of dealers’ pricing of these instruments. However, the price at which dealers value a particular derivative and the price that the same dealers would actually be willing to pay for such derivative should the Fund wish or be forced to sell such position may be materially different. Such differences can result in an overstatement of the Fund’s NAV and may materially adversely affect the Fund in situations in which the Fund is required to sell derivative instruments. Exchange-traded derivatives and OTC derivative transactions submitted for clearing through a central counterparty have become subject to minimum initial and variation margin requirements set by the relevant clearinghouse, as well as possible margin requirements mandated by the SEC or the Commodity Futures Trading Commission (“CFTC”). The SEC, CFTC and federal banking regulators also have imposed margin requirements on certain non-cleared OTC derivatives. As applicable, margin requirements will increase the overall costs for the Fund.

See “Risks—Strategic Transactions and Derivatives Risk.”

Counterparty Risk. The Fund will be subject to credit risk with respect to the counterparties to the derivative contracts purchased by the Fund. Because derivative transactions in which the Fund may engage may involve instruments that are not traded on an exchange or cleared through a central counterparty but are instead traded between counterparties based on contractual relationships, the Fund is subject

to the risk that a counterparty will not perform its obligations under the related contracts. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Fund may experience significant delays in obtaining any recovery in bankruptcy or other reorganization proceedings. The Fund may obtain only a limited recovery, or may obtain no recovery, in such circumstances. Although the Fund intends to enter into transactions only with counterparties that the Advisor believes to be creditworthy, there can be no assurance that, as a result, a counterparty will not default and that the Fund will not sustain a loss on a transaction. In the event of the counterparty’s bankruptcy or insolvency, the Fund’s collateral may be subject to the conflicting claims of the counterparty’s creditors, and the Fund may be exposed to the risk of a court treating the Fund as a general unsecured creditor of the counterparty, rather than as the owner of the collateral. See “Risks—Counterparty Risk.”

Risk Associated with Recent Market Events. The global financial crisis that began in 2008 caused a significant decline in the value and liquidity of many securities and unprecedented volatility in the markets. Periods of market volatility remain, and may continue to occur in the future, in response to various political, social and economic events both within and outside of the United States. These conditions have resulted in, and in many cases continue to result in, greater price volatility, less liquidity, widening credit spreads and a lack of price transparency, with many securities remaining illiquid and of uncertain value. Such market conditions may adversely affect the Fund, including by making valuation of some of the Fund’s securities uncertain and/or result in sudden and significant valuation increases or declines in the Fund’s holdings. If there is a significant decline in the value of the Fund’s portfolio, this may impact the asset coverage levels for any outstanding leverage the Fund may have.

Risks resulting from any future debt or other economic crisis could also have a detrimental impact on the global economic recovery, the financial condition of financial institutions and the Fund’s business, financial condition and results of operation. Market and economic disruptions have affected, and may in the future affect, consumer confidence levels and spending, personal bankruptcy rates, levels of incurrence and default on consumer debt and home prices, among other factors. To the extent uncertainty regarding the U.S. or global economy negatively impacts consumer confidence and consumer credit factors, the Fund’s business, financial condition and results of operations could be significantly and adversely affected. Downgrades to the credit ratings of major banks could result in increased borrowing costs for such banks and negatively affect the broader economy. Moreover, Federal Reserve policy, including with respect to certain interest rates, may also adversely affect the value, volatility and liquidity of dividend- and interest-paying securities. Market

volatility, rising interest rates and/or unfavorable economic conditions could impair the Fund’s ability to achieve its investment objective.

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, ongoing epidemics of infectious diseases in certain parts of the world, terrorist attacks in the United States and around the world, social and political discord, debt crises (such as the Greek crisis), sovereign debt downgrades, increasingly strained relations between the United States and a number of foreign countries, including traditional allies, such as certain European countries, and 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 (the “EU”) or the European Monetary Union (the “EMU”), 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.

The decision made in the British referendum of June 23, 2016 to leave the EU (“Brexit”) has led to volatility in the financial markets of the United Kingdom and more broadly across Europe and may also lead to weakening in consumer, corporate and financial confidence in such markets. The formal notification to the European Council required under Article 50 of the Treaty on EU was made on March 29, 2017, triggering a two year period during which the terms of exit were negotiated. Pursuant to an agreement between the United Kingdom and the EU, the United Kingdom left the EU on January 31, 2020 subject to a transitional period ending December 31, 2020. The longer term economic, legal, political and social framework to be put in place between the United Kingdom and the EU are unclear at this stage and are likely to lead to ongoing political and economic uncertainty and periods of exacerbated volatility in both the United Kingdom and in wider European markets for some time. In particular, the decision made in 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. This mid- to long-term uncertainty may have an adverse effect on the economy generally and on the ability of the Fund to execute its strategies and to receive attractive returns. 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, for the Fund to execute prudent currency hedging policies. Potential decline in the value of the British Pound and/or the Euro against other currencies, along with the potential downgrading of the United Kingdom’s sovereign credit rating, may also have an impact

on the performance of portfolio companies or investments located in the United Kingdom 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.

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. See “Risks—Market Disruption and Geopolitical Risk.”

Regulation and Government Intervention Risk. The U.S. Government and the Federal Reserve, as well as certain foreign governments, have in the past taken actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility. The withdrawal of Federal Reserve or other U.S. or non-U.S. governmental support could negatively affect financial markets generally and reduce the value and liquidity of certain securities. Additionally, with continued economic recovery and the cessation of certain market support activities, the Fund may face a heightened level of interest rate risk as a result of a rise or increased volatility in interest rates.

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 objective. See “Risks—Regulation and Government Intervention Risk.”

Legal, Tax and Regulatory Risks. Legal, tax and regulatory changes could occur that may have material adverse effects on the Fund. For example, the regulatory and tax environment for derivative instruments in which the Fund may participate is evolving, and such changes in the regulation or taxation of derivative instruments may have material adverse effects on the value of derivative instruments held by the Fund and the ability of the Fund to pursue its investment strategies.

To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies (“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 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. See “Risks—Legal, Tax and Regulatory Risks.”

Potential Conflicts of Interest of the Advisor and Others. The investment activities of BlackRock, Inc. (“BlackRock”), the ultimate parent company of the Advisor, and its affiliates (including BlackRock and its subsidiaries (collectively, the “Affiliates”)), The PNC Financial Services Group, Inc. (which, through a subsidiary, has a significant economic interest in BlackRock) and its subsidiaries (each with The PNC Financial Services Group, Inc., an “Entity” and collectively, the “Entities”), 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, its Affiliates and the Entities 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, its Affiliates and the Entities intend to engage in such activities and may receive compensation from third parties for their services. None of BlackRock, its Affiliates or the Entities are under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, BlackRock, its Affiliates and the Entities 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 Entity or another account managed by an Affiliate or an Entity and it is possible that the Fund could sustain losses during periods in which one or more Affiliates, Entities and other accounts achieve profits on their trading for proprietary or other accounts.

Anti-Takeover Provisions Risk. The Fund’s Articles of Incorporation (the “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 in the Charter and Bylaws.”

Additional Risks. For additional risks relating to investments in the Fund, including “Repurchase Agreements Risk,” “When-Issued, Forward Commitment and Delayed Delivery Transactions Risk,” “Securities Lending Risk,” “Swaps Risk,” “Short Sales Risk,” “Inflation Risk,” “Deflation Risk,” “Market and Selection Risk,” “LIBOR and Other Reference Rates Risk,” “Regulation as a ‘Commodity Pool,’” “Failures of Futures Commission Merchants and Clearing Organizations Risk,” “Investment Company Act Regulations,” “Legislation Risk,” “Defensive Investing Risk,” “Decision-Making Authority Risk,” “Management Risk,” “Valuation Risk,” “Reliance on the Advisor Risk,” “Reliance on Service Providers Risk,” “Information Technology Systems Risk,” “Cyber Security Risk,” “Misconduct of Employees and of Service Providers Risk,” “Special Risks for Holders of Rights,” and “Portfolio Turnover Risk,” please see “Risks” beginning on page 54 of this Prospectus.

The following example illustrates the expenses that you would pay on a $1,000 investment in common shares, assuming (i) total net annual expenses of [●]% of net assets attributable to common shares, and (ii) a 5% annual return:

The example should not be considered a representation of future expenses. The example assumes that the estimated “Other expenses” set forth in the Estimated Annual Expenses table are accurate and that all dividends and distributions are reinvested at NAV. Actual expenses may be greater or less than those assumed. Moreover, the Fund’s actual rate of return may be greater or less than the hypothetical 5% return shown in the example.

The financial highlights table is intended to help you understand the Fund’s financial performance for the periods presented. Certain information reflects financial results for a single Fund Share. The information for the fiscal years ended April 30, 2019, 2018, 2017, 2016 and 2015 has been audited by [●], independent registered public accounting firm for the Fund. The information for the fiscal period ended October 31, 2019 is unaudited. The report of [●] is included in the Fund’s April 30, 2019 Annual Report, and is incorporated by reference into the SAI. The Fund’s financial statements are included in the Fund’s Annual Report and Semi-Annual Report and are incorporated by reference into the SAI.

The net proceeds from the issuance of common shares hereunder will be invested in accordance with the Fund’s investment objective and policies as stated below. We currently anticipate that we will be able to invest all of the net proceeds in accordance with our investment objective and policies within approximately three months from the date on which the proceeds from an offering are received by the Fund. Pending such investment, it is anticipated that the proceeds will be invested in short-term investment grade securities or in high quality, short-term money market instruments.

The Fund is a diversified, closed-end management investment company registered under the Investment Company Act. The Fund is incorporated as a Maryland corporation pursuant to its Charter governed by the laws of the State of Maryland. The Fund was incorporated under the laws of the State of Maryland on April 15, 1993 and commenced operations on June 25, 1993. The Fund was known as MuniAssets Fund, Inc. prior to September 14, 2006. The Fund’s principal office is located at 100 Bellevue Parkway, Wilmington, Delaware 19809, and its telephone number is (800) 882-0052. The Fund’s common shares are traded on the NYSE under the symbol “MUA.”

The Fund is authorized to issue 200,000,000 shares of capital stock, par value $.10 per share, all of which shares initially are 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, when issued and outstanding, will be fully paid and non-assessable. Stockholders are entitled to share pro rata in the net assets of the Fund available for distribution to stockholders upon liquidation of the Fund. Stockholders are entitled to one vote for each share held.

In the event that the Fund issues preferred shares and so long as any of the Fund’s preferred shares are outstanding, holders of common shares will not be entitled to receive any net income of or other distributions from the Fund unless all accumulated dividends on preferred shares have been paid, and unless asset coverage (as defined in the 1940 Act) with respect to preferred shares would be at least 200% after giving effect to such distributions. See “Leverage—Preferred Shares.”

The Fund will send unaudited reports at least semi-annually and audited annual financial statements to all of its stockholders.

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 and other factors beyond the control of the Fund, the Fund cannot assure you that 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.

The Fund’s outstanding common shares are, and when issued, the common shares offered by this Prospectus will be, publicly held and listed and traded on the NYSE under the symbol “MUA.” The Fund determines its NAV on a daily basis. The following table sets forth, for the quarters indicated, the highest and lowest daily closing prices on the NYSE per common share, and the NAV per common share and the premium to or discount from NAV, on the date of each of the high and low market prices. The table also sets forth the number of common shares traded on the NYSE during the respective quarters.

As of [●], 2020, the NAV per common share of the Fund was $[●]and the market price per common share was $[●], representing a premium to NAV of [●]%. Common shares of the Fund have historically traded at both a premium and discount to NAV.

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 1940 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 Advisor from managing the Fund’s portfolio in accordance with the Fund’s investment objective and policies. Please see “Description of Capital Stock” in the SAI for more information.

The Fund’s investment objective is to provide high current income exempt from Federal income taxes by investing primarily in a portfolio of medium to lower grade or unrated municipal obligations the interest on which, in the opinion of bond counsel to the issuer, is exempt from Federal income taxes. The Fund seeks to achieve its investment objective by investing at least 80% of its assets, except during temporary defensive periods, in Municipal Bonds. The Fund at all times, except during temporary defensive periods, will maintain at least 65% of its assets in Municipal Bonds which are rated in any one of the medium and lower rating categories of a nationally recognized statistical rating organization or are unrated. These ratings are currently Baa (Moody’s) or BBB (S&P or Fitch) or lower. These are fundamental policies of the Fund and, therefore, may not be changed without the approval of a majority of the Fund’s outstanding voting shares as defined in the 1940 Act. The Fund may invest directly in such securities or synthetically through the use of derivatives. The Fund is not intended as, and you should not construe it to be, a complete investment program. There can be no assurance that the Fund’s investment objective will be achieved or that the Fund’s investment program will be successful.

The Fund has the authority to invest as much as 35% of its total assets in Municipal Bonds in the higher rating categories of nationally recognized statistical rating organizations (ratings of A or higher by Moody’s, S&P or Fitch or comparable unrated securities). In addition, the Fund reserves the right to temporarily invest more than 20% of its total assets in Temporary Investments for defensive purposes when, in the opinion of the Advisor, prevailing market or financial conditions warrant. The Fund does not invest more than 25% of its total assets (taken at market value) in Municipal Bonds whose issuers are located in the same state. As used throughout this Prospectus and the Statement of Additional Information, “total assets” of the Fund means the Fund’s net assets plus the amount of any borrowings for investment purposes.

Ordinarily, the Fund does not intend to realize significant interest income that is subject to Federal income taxes. However, the Fund may invest all or a portion of its assets in certain tax-exempt securities classified as “private activity bonds” (previously defined as “PABs”) (in general, bonds that benefit non-governmental entities) that may subject certain investors in the Fund to a Federal alternative minimum tax.

The Fund may invest in Non-Municipal Tax-Exempt Securities, which could include trust certificates, partnership interests or other instruments evidencing interest in one or more long-term Municipal Bonds.

Non-Municipal Tax-Exempt Securities also may include securities issued by other investment companies that invest in Municipal Bonds, to the extent such investments are permitted by the Fund’s investment restrictions and applicable law.

The Fund ordinarily does not intend to realize significant investment income not exempt from federal income taxes. From time to time, the Fund may realize taxable capital gains.

The Fund seeks to reduce risk through investing in multiple issuers, credit analysis and monitoring of current developments regarding the obligor and trends in both the economy and financial markets. The Advisor will use various means to research the stability and/or potential for improvement of various municipal issuers in connection with the proposed purchase of their securities by the Fund. Evaluation of each Municipal Bond may include the analysis of financial performance, debt structure, economic factors and the administrative structure of the issuer. Additionally, the priority of liens and the overall structure of the particular issue may be factors that will determine suitability for purchase. Further investigation may be performed and may include, among other things, discussions with project management, corporate officers and industry experts as well as site inspections, area analysis, and project and financial projection analysis. All purchases and sales also may be subject to the review of market data, economic projections and the performance of the financial markets. Certain economic indicators also may be monitored. Additionally, the Advisor will vary the average maturity of the Fund’s portfolio securities based upon its assessment of economic and market conditions.

Set forth below is a detailed description of the Municipal Bonds in which the Fund invests. Information with respect to ratings assigned to tax-exempt obligations that the Fund may purchase is set forth in “Appendix A—Description of Municipal Bond Ratings” in the Statement of Additional Information. Obligations are included within the term Municipal Bonds if the interest paid thereon is excluded from gross income for federal income tax purposes in the opinion of bond counsel to the issuer.

Municipal Bonds 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 PABs 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 Bonds. The interest on Municipal Bonds may bear a fixed rate or be payable at a variable or floating rate. The two principal classifications of Municipal Bonds are “general obligation” bonds and “revenue” bonds, which latter category includes PABs and, for bonds issued on or before August 15, 1986, industrial development bonds. Municipal Bonds typically are issued to finance public projects, such as roads or public buildings, to pay general operating expenses or to refinance outstanding debt. Municipal Bonds 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 Bonds 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 Bonds 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.

The Municipal Bonds in which the Fund invests pay interest or income that, in the opinion of bond counsel to the issuer, is exempt from regular Federal income tax. The Advisor does not conduct its own analysis of the tax status of the interest paid by Municipal Bonds held by the Fund, but will rely on the opinion of counsel to the issuer of each such instrument. The Fund may also invest in Municipal Bonds issued by United States Territories (such as Puerto Rico or Guam) that are exempt from regular Federal income tax. In addition to the types of Municipal Bonds described in this Prospectus, the Fund may invest in other securities that pay interest or income that is, or make other distributions that are, exempt from regular Federal income tax and/or state and local personal taxes, regardless of the technical structure of the issuer of the instrument. The Fund treats all of such tax-exempt securities as Municipal Bonds.

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

The Fund has not established any limit on the percentage of its portfolio that may be invested in PABs. The Fund may not be a suitable investment for investors who are already subject to the federal alternative minimum tax or who would become subject to the federal alternative minimum tax as a result of an investment in the Fund’s common shares.

General Obligation Bonds. General obligation bonds are typically secured by the issuer’s pledge of its faith, credit and taxing power for the repayment of principal and the payment of 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 or special obligation bonds are typically 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.

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

Municipal Commercial Paper. Municipal commercial paper is generally unsecured and issued to meet short-term financing needs. The lack of security presents some risk of loss to the Fund since, in the event of an issuer’s bankruptcy, unsecured creditors are repaid only after the secured creditors out of the assets, if any, that remain.

PABs. The Fund may purchase Municipal Bonds classified as PABs. Interest received on certain PABs is treated as an item of “tax preference” for purposes of the federal alternative minimum tax and may impact the overall tax liability of certain investors in the Fund. PABs, formerly referred to as industrial development bonds, are issued by, or on behalf of, states, municipalities or public authorities to obtain funds to provide privately operated housing facilities, airport, mass transit or port facilities, sewage disposal, solid waste disposal or hazardous waste treatment or disposal facilities and certain local facilities for water supply, gas or electricity. Other types of PABs, the proceeds of which are used for the construction, equipment, repair or improvement of privately operated industrial or commercial facilities, may constitute Municipal Bonds, although the federal tax laws may 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. PABs 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. The 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.

Moral Obligation Bonds. Municipal Bonds may also include “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. Also included within the general category of Municipal Bonds are certificates of participation (“COPs”) issued by government authorities or entities to finance the acquisition or construction of equipment, land and/or facilities. COPs represent participations in a lease, an installment purchase contract or a conditional sales contract (hereinafter collectively called “lease obligations”) relating to such equipment, land or facilities. Municipal leases, like other municipal debt obligations, are subject to the risk of non-payment. Although lease obligations do not constitute general obligations of the issuer for which the issuer’s unlimited taxing power is pledged, a lease obligation is frequently backed by the issuer’s covenant to budget for, appropriate and make the payments due under the lease obligation. However, certain lease obligations contain “non-appropriation” clauses which provide that the issuer has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although “non-appropriation” lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult and the value of the property may be insufficient to issue lease obligations. Certain investments in lease obligations may be illiquid.

The ability of issuers of municipal leases to make timely lease payments may be adversely impacted in general economic downturns and as relative governmental cost burdens are allocated and reallocated among federal, state and local governmental units. Such non-payment would result in a reduction of income to the Fund, and could result in a reduction in the value of the municipal lease experiencing non-payment and a potential decrease in the NAV of the Fund. Issuers of municipal lease obligations might seek protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, the Fund could experience delays and limitations with respect to the collection of principal and interest on such municipal leases and the Fund may not, in all circumstances, be able to collect all principal and interest to which it is entitled. To enforce its rights in the event of a default in lease payments, the Fund might take possession of and manage the assets securing the issuer’s obligations on such securities, which may increase the Fund’s operating expenses and adversely affect the NAV of the Fund. When the lease contains a non-appropriation clause, however, the failure to pay would not be a

default and the Fund would not have the right to take possession of the assets. Any income derived from the Fund’s ownership or operation of such assets may not be tax-exempt or may fail to generate qualifying income for purposes of the income tests applicable to regulated investment companies. In addition, the Fund’s intention to qualify as a regulated investment company under the Internal Revenue Code of 1986, may limit the extent to which the Fund may exercise its rights by taking possession of such assets, because as a regulated investment company the Fund is subject to certain limitations on its investments and on the nature of its income.

Zero-Coupon Bonds. Municipal Bonds may include zero-coupon bonds. Zero-coupon bonds 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 bond is entitled to receive the par value of the security.

While interest payments are not made on such 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 bond, 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 bonds are more exposed to interest rate risk than shorter term zero-coupon bonds. 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 U.S. federal income tax and accounting purposes prior to the receipt of cash payments. Zero-coupon bonds 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.

In addition to the above-described risks, there are certain other risks related to investing in zero-coupon bonds. 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.

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.

Special Taxing Districts. Special taxing districts are organized to plan and finance infrastructure developments to induce residential, commercial and industrial growth and redevelopment. The bond financing methods such as tax increment finance, tax assessment, special services district and Mello-Roos bonds (a type of municipal security established by the Mello-Roos Community Facilities 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.

Indexed and Inverse Floating Rate Securities. The Fund may invest in Municipal Bonds (and Non-Municipal Tax-Exempt Securities) that yield a return based on a particular index of value or interest rates. For example, the Fund may invest in Municipal Bonds that pay interest based on an index of Municipal Bond interest rates. The principal amount payable upon maturity of certain Municipal Bonds also may be based on the value of the index. To the extent the Fund invests in these types of Municipal Bonds, the Fund’s return on such Municipal Bonds will be subject to risk with respect to the value of the particular index. Interest and principal payable on the Municipal Bonds may also be based on relative changes among particular indices. Also, the Fund may invest in so-called “inverse floating rate bonds” or “residual interest bonds” on which the interest rates vary inversely with a short-term floating rate (which may be reset periodically by a Dutch auction, a remarketing agent, or by reference to a short-term tax-exempt interest rate index). The Fund may purchase synthetically created inverse floating rate bonds evidenced by custodial or trust receipts. Generally, income on inverse floating rate bonds will decrease when short-term interest rates increase, and will increase when short-term interest rates decrease. Such securities have the effect of providing a degree of investment leverage, since they may increase or decrease in value in response to changes, as an illustration, in market interest rates at a rate which is a multiple (typically two) of the rate at which fixed rate long-term tax-exempt securities increase or decrease in response to such changes. As a result, the market values of such securities will generally be more volatile than the market values of fixed rate tax-exempt securities. To seek to limit the volatility of these securities, the Fund may purchase inverse floating rate bonds with shorter-term maturities or limitations on the extent to which the interest rate may vary. Certain investments in such obligations may be illiquid. See “The Fund’s Investments—Leverage—Tender Option Bond Transactions.”

When-Issued Securities, Delayed Delivery Securities and Forward Commitments. The Fund may purchase or sell securities that it is entitled to receive on a when-issued basis. The Fund may also purchase or sell securities on a delayed delivery basis. The Fund may also purchase or sell securities through a forward commitment. These transactions involve the purchase or sale of securities by the Fund at an established price with payment and delivery taking place in the future. The purchase will be recorded on the date the Fund enters into the commitment and the value of the securities will thereafter be reflected in the Fund’s NAV. The Fund has not established any limit on the percentage of its assets that may be committed in connection with these transactions. At the time the Fund enters into a transaction on a when-issued basis, it will segregate or designate on its books and records cash or liquid assets with a value not less than the value of the when-issued securities.

There can be no assurance that a security purchased on a when-issued basis will be issued or that a security purchased or sold through a forward commitment will be delivered. 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.

If deemed advisable as a matter of investment strategy, the Fund may dispose of or renegotiate a commitment after it has been entered into, and may sell securities it has committed to purchase before those securities are delivered to the Fund on the settlement date. In these cases the Fund may realize a taxable capital gain or loss.

When the Fund engages in when-issued, delayed delivery or forward commitment transactions, it relies on the other party to consummate the trade. Failure of such party to do so may result in the Fund’s incurring a loss or missing an opportunity to obtain a price considered to be advantageous.

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 market value 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.

Yields. Yields on Municipal Bonds are dependent on a variety of factors, including the general condition of the money market and of the Municipal Bond market, the size of a particular offering, the financial condition of the issuer, the maturity of the obligation and the rating of the issue. The ability of the Fund to achieve its investment objective is also dependent on the continuing ability of the issuers of the securities in which the Fund invests to meet their obligations for the payment of interest and principal when due. There are variations in the risks involved in holding Municipal Bonds, both within a particular classification and between classifications, depending on numerous factors. Furthermore, the rights of owners of Municipal Bonds and the obligations of the issuer of such Municipal Bonds may be subject to applicable bankruptcy, insolvency and similar laws and court decisions affecting the rights of creditors generally and to general equitable principles, which may limit the enforcement of certain remedies.

“High Yield” or “Junk” Bonds. The Fund is required to invest at least 65% of its assets in Municipal Bonds which are rated in any one of the medium and lower rating categories of a nationally recognized statistical rating organization or are unrated. These ratings are currently Baa (Moody’s) or BBB (S&P or Fitch) or lower. Information with respect to ratings assigned to tax-exempt obligations that the Fund may purchase is set forth in “Appendix A—Description of Municipal Bond Ratings” in the Statement of Additional Information. Municipal Bonds of below investment grade quality (“Ba/BB” or below) are commonly known as “junk bonds.” Securities rated below investment grade are judged to have speculative characteristics with respect to their interest and principal payments. Such securities may 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.

The Fund may purchase and sell futures contracts, enter into various interest rate transactions and swap contracts (including, but not limited to, credit default swaps) and may purchase and sell exchange-listed and OTC put and call options on securities and swap contracts, financial indices and futures contracts and use other derivative instruments or management techniques. These Strategic Transactions may be used for duration management and other risk management purposes, subject to the Fund’s investment restrictions. While the Fund’s use of Strategic Transactions is intended to reduce the volatility of the NAV of the Fund’s common shares, the NAV of the Fund’s common shares will fluctuate. No assurance can be given that the Fund’s Strategic Transactions will be effective.

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 ability of the Fund to use Strategic Transactions successfully will depend on the Advisor’s ability to predict pertinent market movements as well as sufficient correlation among the instruments, which cannot be assured. Strategic Transactions subject the Fund to the risk that, if the Advisor incorrectly forecasts market values, interest

rates or other applicable factors, the Fund’s performance could suffer. Certain of these Strategic Transactions, such as investments in inverse floating rate securities and credit default swaps, may provide investment leverage to the Fund’s portfolio. The Fund is not required to use derivatives or other portfolio strategies to seek to hedge its portfolio and may choose not to do so.

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. Furthermore, the Fund may only engage in Strategic Transactions from time to time and may not necessarily be engaging in hedging activities when movements in interest rates occur.

Inasmuch as any obligations of the Fund that arise from the use of Strategic Transactions will be covered by segregated or earmarked liquid assets or offsetting transactions, the Fund and the Advisor believe such obligations do not constitute senior securities and, accordingly, will not treat such transactions as being subject to its borrowing restrictions. Additionally, segregated or earmarked liquid assets, amounts paid by the Fund as premiums and cash or other assets held in margin accounts with respect to Strategic Transactions are not otherwise available to the Fund for investment purposes.

Certain federal income tax requirements 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.

Put and Call Options on Securities and Indices. The Fund may purchase and sell put and call options on securities and indices. A put option gives the purchaser of the option the right to sell and the writer the obligation to buy the underlying security at the exercise price during the option period. The Fund may also purchase and sell options on bond indices (“index options”). 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 bond index upon which the option is based is greater, in the case of a call, or less, in the case of a put, than the exercise price of the option. The purchase of a put option on a debt security could protect the Fund’s holdings in a security or a number of securities against a substantial decline in the market value. A call option gives the purchaser of the option the right to buy and the seller the obligation to sell the underlying security or index at the exercise price during the option period or for a specified period prior to a fixed date. The purchase of a call option on a security could protect the Fund against an increase in the price of a security that it intended to purchase in the future.

Writing Covered Call Options. The Fund is authorized to write (i.e., sell) covered call options with respect to Municipal Bonds it owns, thereby giving the holder of the option the right to buy the underlying security covered by the option from the Fund at the stated exercise price until the option expires. The Fund writes only covered call options, which means that so long as the Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option.

The Fund receives a premium from writing a call option, which increases the Fund’s return on the underlying security in the event the option expires unexercised or is closed out at a profit. By writing a call, the Fund limits its opportunity to profit from an increase in the market value of the underlying security above the exercise price of the option for as long as the Fund’s obligation as a writer continues. Covered call options serve as a partial hedge against a decline in the price of the underlying security. The Fund may engage in closing transactions in order to terminate outstanding options that it has written.

Additional Information About 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 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 are considered by the staff of the SEC to 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 Fund may engage in options and futures transactions on exchanges and options in the over-the-counter markets. The Fund will only enter into OTC options with counterparties the Advisor believes to be creditworthy at the time they enter into such transactions.

The hours of trading for options on debt securities may not conform to the hours during which the underlying securities are traded. 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 be reflected in the option markets.

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 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, which varies, but is generally about 5% of the contract amount, 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 the 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 nominal 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. With respect to U.S. Government securities, currently there are financial futures contracts based on long-term U.S. Treasury bonds, U.S. Treasury notes, Government National Mortgage Association (“GNMA”) Certificates and three-month U.S. Treasury bills. The Fund may purchase and write call and put options on futures contracts on U.S. Government securities and purchase and sell Municipal Bond Index futures contracts in connection with its hedging strategies.

The Fund also may engage in other futures contracts transactions such as futures contracts on other municipal bond indices that may become available if the Advisor should determine that there is normally a sufficient correlation between the prices of such futures contracts and the Municipal Bonds 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 the 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.

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 Advisor has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act (“CEA”) pursuant to Rule 4.5 under the CEA. The Advisor is not, therefore, subject to registration or regulation as a “commodity pool operator” under the CEA in respect of the Fund.

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 Advisor will seek to minimize the Fund’s exposure to counterparty risk by entering into such transactions with counterparties the Advisor believes to be creditworthy at the time it enters into the transaction. Certain 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.

The Fund may invest in short-term tax-exempt and taxable securities subject to the limitations set forth above. The tax-exempt money market securities may include municipal notes, municipal commercial paper, Municipal Bonds with a remaining maturity of less than one year, variable rate demand notes and participations therein. Municipal notes include tax anticipation notes, bond anticipation notes, revenue anticipation notes and grant anticipation notes. Anticipation notes are sold as interim financing in anticipation of tax collection, bond sales, government grants or revenue receipts. Municipal commercial paper refers to short-term unsecured promissory notes generally issued to finance short-term credit needs. The taxable money market securities in which the Fund may invest as Temporary Investments consist of U.S. Government securities, U.S. Government agency securities, domestic bank or savings institution certificates of deposit and bankers’ acceptances, short-term corporate debt securities such as commercial paper and repurchase agreements. These Temporary Investments must have a stated maturity not in excess of one year from the date of purchase. The Fund may not invest in any security issued by a commercial bank or a savings institution unless the bank or institution is organized and operating in the United States, has total assets of at least one billion dollars and is a member of the Federal Deposit Insurance Corporation (“FDIC”), except that up to 10% of total assets may be invested in certificates of deposit of smaller institutions if such certificates are fully insured by the FDIC.

Short-term taxable fixed-income investments include, without limitation, the following:

(1) U.S. Government securities, including bills, notes and bonds differing as to maturity and rates of interest that are either issued or guaranteed by the U.S. Treasury or by U.S. Government agencies or instrumentalities. U.S. Government securities include securities issued by (a) the Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, and the Government National Mortgage Association, whose securities are supported by the full faith and credit of the United States; (b) the Federal Home Loan Banks, Federal Intermediate Credit Banks, and the Tennessee Valley Authority, whose securities are supported by the right of the agency to borrow from the U.S. Treasury; (c) the Federal National Mortgage Association, whose securities are supported by the discretionary authority of the U.S. Government to purchase certain obligations of the agency or instrumentality; and (d) the Student Loan Marketing Association, whose securities are supported only by its credit. While the U.S. Government provides financial support to such U.S. Government-sponsored agencies or instrumentalities, no assurance can be given that it always will do so since it is not so obligated by law. The U.S. Government, its agencies and instrumentalities do not guarantee the market value of their securities. Consequently, the value of such securities may fluctuate.

(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 FDIC.

(3) Repurchase agreements, which involve purchases of debt securities. At the time the Fund purchases securities pursuant to a repurchase agreement, it simultaneously agrees to resell and redeliver such securities to the seller, who also simultaneously agrees to buy back the securities at a fixed price and time. This assures a predetermined yield for the Fund during its holding period, since the resale price is always greater than the purchase price and reflects an agreed-upon market rate. Such actions afford an opportunity for the Fund to invest temporarily available cash. The Fund may enter into repurchase agreements only with respect to obligations of the U.S. Government, its agencies or instrumentalities; certificates of deposit; or bankers’ acceptances in which the Fund may invest. Repurchase agreements may be considered loans to the seller, collateralized by the underlying securities. The risk to the Fund is limited to the ability of the seller to pay the agreed-upon sum on the repurchase date; in the event of default, the repurchase agreement provides that the Fund is entitled to sell the underlying collateral. If the value of the collateral declines after the agreement is entered into, and if the seller defaults under a repurchase agreement when the value of the underlying collateral is less than the repurchase

price, the Fund could incur a loss of both principal and interest. The Advisor monitors the value of the collateral at the time the action is entered into and at all times during the term of the repurchase agreement. The Advisor does so in an effort to determine that the value of the collateral always equals or exceeds the agreed-upon repurchase price to be paid to the Fund. If the seller were to be subject to a federal bankruptcy proceeding, the ability of the Fund to liquidate the collateral could be delayed or impaired because of certain provisions of the bankruptcy laws.

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

Short-term tax-exempt fixed-income securities are securities that are exempt from regular federal income tax and mature within three years or less from the date of issuance. Short-term tax-exempt fixed-income securities include, without limitation, the following:

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.

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.

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.

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.

Bank Notes are notes issued by local government bodies and agencies 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.

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 bonds 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 objective, policies and limitations. Such notes may be issued for different purposes and may be secured differently from those mentioned above.

In order to seek to hedge the value of the Fund against interest rate fluctuations or to seek to increase the Fund’s return, the Fund may enter into interest rate swap transactions such as Municipal Market Data AAA Cash Curve swaps (“MMD Swaps”) or Securities Industry and Financial Markets Association Municipal Swap Index swaps (“SIFMA Swaps”). To the extent that the Fund enters into these transactions, the Fund expects to do so primarily to preserve a return or spread on a particular investment or portion of its portfolio as a duration management technique or to protect against any increase in the price of securities the Fund anticipates purchasing at a later date. The Fund may enter into these transactions primarily as a hedge or for duration or risk management rather than as a speculative investment. However, the Fund also may invest in MMD Swaps and SIFMA Swaps to seek to enhance return or gain or to increase the Fund’s yield, for example, during periods of steep interest rate yield curves (i.e., wide differences between short-term and long-term interest rates).

The Fund may purchase and sell SIFMA Swaps in the SIFMA swap market. In a SIFMA Swap, the Fund exchanges with another party their respective commitments to pay or receive interest (e.g., an exchange of fixed rate payments for floating rate payments linked to the SIFMA Municipal Swap Index). Because the underlying index is a tax-exempt index, SIFMA Swaps may reduce cross-market risks incurred by the Fund and increase the Fund’s ability to hedge effectively. SIFMA Swaps are typically quoted for the entire yield curve, beginning with a seven day floating rate index out to 30 years. The duration of a SIFMA Swap is approximately equal to the duration of a fixed-rate Municipal Bond with the same attributes as the swap (e.g., coupon, maturity, call feature).

The Fund may also purchase and sell MMD Swaps, also known as MMD rate locks. An MMD Swap permits the Fund to lock in a specified municipal interest rate for a portion of its portfolio to preserve a return on a particular investment or a portion of its portfolio as a duration management technique or to protect against any increase in the price of securities to be purchased at a later date. By using an MMD Swap, the Fund can create a synthetic long or short position, allowing the Fund to select the most attractive part of the yield curve. An MMD Swap is a contract between the Fund and an MMD Swap provider pursuant to which the parties agree to make payments to each other on a notional amount, contingent upon whether the Municipal Market Data AAA General Obligation Scale is above or below a specified level on the expiration date of the contract. For example, if the Fund buys an MMD Swap and the Municipal Market Data AAA General Obligation Scale is below the specified level on the expiration date, the counterparty to the contract will make a payment to the Fund equal to the specified level minus the actual level, multiplied by the notional amount of the contract. If the Municipal Market Data AAA General Obligation Scale is above the specified level on the expiration date, the Fund will make a payment to the counterparty equal to the actual level minus the specified level, multiplied by the notional amount of the contract.

In connection with investments in SIFMA and MMD Swaps, there is a risk that municipal yields will move in the opposite direction than anticipated by the Fund, which would cause the Fund to make payments to its counterparty in the transaction that could adversely affect the Fund’s performance.

The Fund has no obligation to enter into SIFMA Swaps or MMD Swaps and may elect not to do so. The net amount of the excess, if any, of the Fund’s obligations over its entitlements with respect to each interest rate

swap will be accrued on a daily basis, and the Fund will segregate or designate on its books and records liquid assets having an aggregate NAV at least equal to the accrued excess.

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 guarantee the parties’ performance under the swap agreement. However, there can be no assurances 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.

The Fund may purchase a Municipal Bond issuer’s right to call all or a portion of such Municipal Bond for mandatory tender for purchase (a “Call Right”). A holder of a Call Right may exercise such right to require a mandatory tender for the purchase of related Municipal Bonds, subject to certain conditions. A Call Right that is not exercised prior to maturity of the related Municipal Bond will expire without value. The economic effect of holding both the Call Right and the related Municipal Bond is identical to holding a Municipal Bond as a non-callable security. Certain investments in such obligations may be illiquid.

The Fund may enter into credit default swap agreements for hedging purposes or to seek to increase its return. 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 a reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the “par value” (full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or 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), if the swap is cash settled. 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 may recover nothing 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 value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value 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 (6) 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 value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value may have significantly decreased. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap.

Credit default swap agreements involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to illiquidity risk, counterparty risk and credit risks. The Fund will enter into credit default swap agreements only with counterparties the Advisor believes to be creditworthy at the time they enter into such transactions. A buyer generally also will lose its investment and recover nothing 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 value it pays to the buyer, resulting in a loss of value to the seller. The Fund’s obligations under a credit default swap agreement will be accrued daily (offset against any amounts owing to the Fund).

The Fund will at all times segregate or designate on its books and records in connection with each such transaction liquid assets or cash with a value at least equal to the Fund’s exposure (any accrued but unpaid net amounts owed by the Fund to any counterparty) on a marked-to-market basis (as calculated pursuant to requirements of the SEC). If the Fund is a seller of protection in a credit default swap transaction, it will segregate or designate on its books and records in connection with such transaction liquid assets or cash with a value at least equal to the full notional amount of the contract. Such segregation or designation will ensure that the Fund has assets available to satisfy its obligations with respect to the transaction and will avoid any potential leveraging of the Fund’s portfolio. Such segregation or designation will not limit the Fund’s exposure to loss.

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 (7) days. There is, however, the possibility that because of default or insolvency the demand feature of VRDOs and Participating 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 the SIFMA Municipal Swap Index 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 which satisfy its short-term maturity and quality standards.

Participating VRDOs provide the Fund with a specified undivided interest (up to 100%) of the underlying obligation and the right to demand payment of the unpaid principal balance plus accrued interest on the Participating VRDOs from the financial institution upon a specified number of days’ notice, not to exceed seven (7) days. In addition, the Participating VRDO is backed by an irrevocable letter of credit or guaranty of the financial institution. The Fund would have an undivided interest in the underlying obligation and thus participate on the same basis as the financial institution in such obligation except that the financial institution typically retains fees out of the interest paid on the obligation for servicing the obligation, providing the letter of credit and issuing the repurchase commitment. The Fund has been advised by its counsel that the Fund should be entitled to treat the income received on Participating VRDOs as interest from tax-exempt obligations as long as the Fund does not invest more than 20% of its total assets in such investments and certain other conditions are met. It is contemplated that the Fund will not invest more than 20% of its assets in Participating VRDOs.

The Temporary Investments, VRDOs and Participating VRDOs in which the Fund may invest will be in the following rating categories at the time of purchase: MIG-1/VMIG-1 through MIG-3/VMIG-3 for notes and VRDOs and Prime-1 through Prime-3 for commercial paper (as determined by Moody’s), SP-1 through SP-2 for notes and A-1 through A-3 for VRDOs and commercial paper (as determined by S&P), or F1 through F3 for notes, VRDOs and commercial paper (as determined by Fitch). Temporary Investments, if not rated, must be of comparable quality in the opinion of the Advisor. In addition, the Fund reserves the right to invest temporarily a greater portion of its assets in Temporary Investments for defensive purposes, when, in the judgment of the Advisor, market conditions warrant.

The Fund may invest in securities pursuant to repurchase agreements. Repurchase agreements may be entered into only with a member bank of the Federal Reserve System or a primary dealer or an affiliate thereof, in U.S. Government securities. 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. 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 Advisor will monitor the value of the collateral at the time the transaction is entered into and throughout 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 Advisor will demand additional collateral from the issuer to increase the value of the collateral to at least that of the repurchase price, including interest.

In general, for federal income tax purposes, repurchase agreements are treated as collateralized loans secured by the securities “sold.” Therefore, amounts earned under such agreements will not be considered tax exempt interest. The treatment of purchase and sales contracts is less certain.

The Fund currently does not intend to borrow money or issue debt securities or preferred shares. The Fund is, however, permitted to borrow money or issue debt securities in an amount up to 33 1/3% of its Managed Assets (50% of its net assets), and issue preferred shares in an amount up to 50% of its Managed Assets (100% of its net assets). “Managed Assets” means the total assets of the Fund (including any assets attributable to money borrowed for investment purposes) minus the sum of the Fund’s accrued liabilities (other than money borrowed for investment purposes). Although it has no present intention to do so, the Fund reserves the right to borrow money from banks or other financial institutions, or issue debt securities or preferred shares, in the future if it believes that market conditions would be conducive to the successful implementation of a leveraging strategy through borrowing money or issuing debt securities or preferred shares. Any such leveraging will not be fully achieved until the proceeds resulting from the use of leverage have been invested in accordance with the Fund’s investment objective and policies.

The Board has authorized the Fund to use economic leverage up to 25% of its total assets. The Fund currently intends to use economic leverage approximately equal to 15% of its total assets at the time the leverage is implemented, but may use economic leverage up to 25% of its total assets under the leverage policy set by the Board without further Board or shareholder approval. The Board could in the future authorize the Fund to use additional leverage up to the maximum amount permitted under the 1940 Act or change the 25% threshold at which Board approval is required to increase leverage, in each case without further shareholder approval.

The use of leverage can create risks. When leverage is employed, the NAV and market price of the common shares and the yield to holders of common shares will be more volatile than if leverage were not used. Changes in the value of the Fund’s portfolio, including securities bought with the proceeds of leverage, will be borne entirely by the holders of common shares. If there is a net decrease or increase in the value of the Fund’s investment portfolio, leverage will decrease or increase, as the case may be, the NAV per common share to a greater extent than if the Fund did not utilize leverage. A reduction in the Fund’s NAV may cause a reduction in the market price of its shares. During periods in which the Fund is using leverage, the fee paid to the Advisor for advisory services will be higher than if the Fund did not use leverage, because the fees paid will be calculated on the basis of the Fund’s Managed Assets, which includes the proceeds from leverage. Any leveraging strategy the Fund employs may not be successful. See “Risks—Leverage Risk.” The Fund currently leverages assets through tender option bonds transactions. See “Risks—Tender Option Bond Risk” for details about the risks associated with the Fund’s use of TOB Residuals.

Certain types of leverage the Fund may use may result in the Fund being subject to covenants relating to asset coverage and portfolio composition requirements. The Fund may be subject to certain restrictions on

investments imposed by one or more lenders or by guidelines of one or more rating agencies, which may issue ratings for any short-term debt securities or preferred shares issued by the Fund. The terms of any borrowings or rating agency guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed by the Investment Company Act. The Advisor does not believe that these covenants or guidelines will impede it from managing the Fund’s portfolio in accordance with its investment objective and policies if the Fund were to utilize leverage.

Under the Investment Company Act, the Fund is not permitted to issue senior securities if, immediately after the issuance of such senior securities, the Fund would have an asset coverage ratio (as defined in the Investment Company Act) of less than 300% with respect to senior securities representing indebtedness (i.e., for every dollar of indebtedness outstanding, the Fund is required to have at least three dollars of assets) or less than 200% with respect to senior securities representing preferred shares (i.e., for every dollar of preferred shares outstanding, the Fund is required to have at least two dollars of assets). The Investment Company Act also provides that the Fund may not declare distributions or purchase its stock (including through tender offers) if, immediately after doing so, it will have an asset coverage ratio of less than 300% or 200%, as applicable. Under the Investment Company Act, certain short-term borrowings (such as for cash management purposes) are not subject to these limitations if (i) repaid within 60 days, (ii) not extended or renewed and (iii) not in excess of 5% of the total assets of the Fund.

Assuming that leverage will represent approximately [●]% of the Trust’s Managed Assets and that the Trust will bear expenses relating to that leverage at an average annual rate of [●]%, the income generated by the Trust’s portfolio (net of estimated expenses) must exceed [●]% in order to cover the expenses specifically related to the Trust’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 securities 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. See “Risks.” The table further reflects the use of leverage representing [●]% of the Fund’s Managed Assets and the Fund’s currently projected annual leverage expense of [●]%.

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) 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.

The Fund currently leverages its assets through the use of TOB Residuals, which are derivative interests in municipal bonds. The TOB Residuals in which the Fund will invest pay interest or income that, in the opinion of counsel to the issuer of such TOB Residuals, is exempt from regular U.S. federal income tax. No independent investigation will be made to confirm the tax-exempt status of the interest or income paid by TOB Residuals held by the Fund. Although volatile, TOB Residuals typically offer the potential for yields exceeding the yields available on fixed rate municipal bonds with comparable credit quality.

TOB Residuals represent beneficial interests in a TOB Trust formed for the purpose of holding municipal bonds contributed by one or more funds. A TOB Trust typically issues two classes of beneficial interests: TOB Floaters, which are sold to third party investors, and TOB Residuals, which are generally issued to the fund(s) that transferred municipal bonds to the TOB Trust. The Fund may invest in both TOB Floaters and TOB Residuals. TOB Floaters may have first priority on the cash flow from the municipal bonds held by the TOB Trust and are enhanced with a liquidity support arrangement from a third party TOBs Liquidity Provider (defined below) which allows holders to tender their position at par (plus accrued interest). The Fund, as a holder of TOB Residuals, is paid the residual cash flow from the TOB Trust. The Fund contributes municipal bonds to the TOB Trust and is paid the cash received by the TOB Trust from the sale of the TOB Floaters, less certain transaction costs, and typically will invest the cash to purchase additional municipal bonds or other investments permitted by its investment policies. If the Fund ever purchases all or a portion of the TOB Floaters sold by the TOB Trust, it may surrender those TOB Floaters together with a proportionate amount of TOB Residuals to the TOB Trust in exchange for a proportionate amount of the municipal bonds owned by the TOB Trust.

Other BlackRock-advised Funds (as defined below) may contribute municipal bonds to a TOB Trust into which the Fund has contributed municipal bonds. If multiple BlackRock-advised Funds participate in the same TOB Trust, the economic rights and obligations under the TOB Residual will generally be shared among the funds ratably in proportion to their participation in the TOB Trust.

The TOB Residuals held by the Fund generally provide the Fund with the right to cause the holders of a proportional share of the TOB Floaters to tender their notes to the TOB Trust at par plus accrued interest. Thereafter, the Fund may withdraw a corresponding share of the municipal bonds from the TOB Trust. As a result, a tender option bond transaction, in effect, creates exposure for the Fund to the entire return of the municipal bonds in the TOB Trust, with a net cash investment by the Fund that is less than the value of the municipal bonds in the TOB Trust. This multiplies the positive or negative impact of the municipal bonds’ return within the Fund (thereby creating leverage). The leverage within a TOB Trust depends on the value of the municipal bonds deposited in the TOB Trust relative to the value of the TOB Floaters it issues.

The Fund may invest in highly leveraged TOB Residuals. A TOB Residual generally is considered highly leveraged if the principal amount of the TOB Floaters issued by the related TOB Trust exceeds 75% of the principal amount of the municipal bonds owned by the TOB Trust.

TOB Trusts are typically supported by a liquidity facility provided by a TOBs Liquidity Provider that allows the holders of the TOB Floaters to tender their TOB Floaters in exchange for payment of par plus accrued interest on any business day (subject to the non-occurrence of a termination event). The tendered TOB Floaters are remarketed by a remarketing agent. In the event of a failed remarketing, the TOB Trust may draw upon a loan

from the TOBs Liquidity Provider to purchase the tendered TOB Floaters. Any loans made by the TOBs Liquidity Provider will be secured by the purchased TOB Floaters held by the TOB Trust and will be subject to an increased interest rate based on number of days the loan is outstanding.

The Fund may invest in a TOB Trust on either a non-recourse or recourse basis. When the Fund invests in TOB Trusts on a non-recourse basis, and the TOBs Liquidity Provider is required to make a payment under the liquidity facility, the TOBs Liquidity Provider will typically liquidate all or a portion of the municipal bonds held in the TOB Trust and then fund the balance, if any, of the Liquidation Shortfall. If the Fund invests in a TOB Trust on a recourse basis, it will typically enter into a reimbursement agreement with the TOBs Liquidity Provider pursuant to which the Fund is required to reimburse the TOBs Liquidity Provider the amount of any Liquidation Shortfall. As a result, if the Fund invests in a recourse TOB Trust, the Fund will bear the risk of loss with respect to any Liquidation Shortfall. If multiple BlackRock-advised Funds participate in any such TOB Trust, these losses will be shared ratably, in proportion to their participation in the TOB Trust.

Under accounting rules, Municipal Bonds of the Fund that are deposited into a TOB Trust are investments of the Fund and are presented on the Fund’s Schedule of Investments and outstanding TOB Floaters issued by a TOB Trust are presented as liabilities in the Fund’s Statement of Assets and Liabilities. Interest income from the underlying Municipal Bonds is recorded by the Fund on an accrual basis. Interest expense incurred on the TOB Floaters and other expenses related to remarketing, administration, trustee and other services to a TOB Trust are reported as expenses of the Fund. In addition, under accounting rules, loans made to a TOB Trust sponsored by the Fund may be presented as loans of the Fund in the Fund’s financial statements even if there is no recourse to the Fund’s assets.

For TOB Floaters, generally, the interest rate earned will be based upon the market rates for municipal bonds with maturities or remarketing provisions that are comparable in duration to the periodic interval of the tender option. Since the tender option feature has a shorter term than the final maturity or first call date of the underlying municipal bonds deposited in the TOB Trust, the holder of the TOB Floaters relies upon the terms of the agreement with the financial institution furnishing the liquidity facility as well as the credit strength of that institution. The perceived reliability and creditworthiness, of many major financial institutions, some of which sponsor and/or provide liquidity support to TOB Trusts increases the risk associated with TOB Floaters. This in turn may reduce the desirability of TOB Floaters as investments, which could impair the viability or availability of TOB Trusts.

The use of TOB Residuals will require the Fund to earmark or segregate liquid assets in an amount equal to any TOB Floaters, plus any accrued but unpaid interest due on the TOB Floaters, issued by TOB Trusts sponsored by, or on behalf of, the Fund that are not owned by the Fund. The use of TOB Residuals may also require the Fund to earmark or segregate liquid assets in an amount equal to loans provided by the TOBs Liquidity Provider to the TOB Trust to purchase tendered TOB Floaters. The Fund reserves the right to modify its asset segregation policies in the future to the extent that such changes are in accordance with applicable regulations or interpretations. Future regulatory requirements or SEC guidance may necessitate more onerous contractual or regulatory requirements, which may increase the costs or reduce the degree of potential economic benefits of TOB Trust transactions or limit the Fund’s ability to enter into or manage TOB Trust transactions.

See “Risk Factors—General Risks of Investing in the Fund—Tender Option Bond Risk” for a description of the risks involved with a TOB issuer.

The Fund is permitted to leverage its portfolio by entering into one or more credit facilities. If the Fund enters into a credit facility, the Fund may be required to prepay outstanding amounts or incur a penalty rate of interest upon the occurrence of certain events of default. The Fund would also likely have to indemnify the lenders under the credit facility against liabilities they may incur in connection therewith. In addition, the Fund

expects that any credit facility would contain covenants that, among other things, likely would limit the Fund’s ability to pay distributions in certain circumstances, incur additional debt, change certain of its investment policies and engage in certain transactions, including mergers and consolidations, and require asset coverage ratios in addition to those required by the Investment Company Act. The Fund may be required to pledge its assets and to maintain a portion of its assets in cash or high-grade securities as a reserve against interest or principal payments and expenses. The Fund expects that any credit facility would have customary covenant, negative covenant and default provisions. There can be no assurance that the Fund will enter into an agreement for a credit facility, or one on terms and conditions representative of the foregoing, or that additional material terms will not apply. In addition, if entered into, a credit facility may in the future be replaced or refinanced by one or more credit facilities having substantially different terms or by the issuance of preferred shares.

The Fund is permitted to leverage its portfolio by issuing preferred shares. Under the Investment Company Act, the Fund is not permitted to issue preferred shares if, immediately after such issuance, the liquidation value of the Fund’s outstanding preferred shares exceeds 50% of its assets (including the proceeds from the issuance) less liabilities other than borrowings (i.e., the value of the Fund’s assets must be at least 200% of the liquidation value of its outstanding preferred shares). In addition, the Fund would not be 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 assets less liabilities other than borrowings is at least 200% of such liquidation value.

The Fund expects that preferred shares, if issued, will pay adjustable rate dividends based on shorter-term interest rates, which would be redetermined periodically by a fixed spread or remarketing process, subject to a maximum rate which would increase over time in the event of an extended period of unsuccessful remarketing. The adjustment period for preferred share dividends could be as short as one day or as long as a year or more. Preferred shares, if issued, could include a liquidity feature that allows holders of preferred shares to have their shares purchased by a liquidity provider in the event that sell orders have not been matched with purchase orders and successfully settled in a remarketing. The Fund expects that it would pay a fee to the provider of this liquidity feature, which would be borne by common shareholders of the Fund. The terms of such liquidity feature could require the Fund to redeem preferred shares still owned by the liquidity provider following a certain period of continuous, unsuccessful remarketing, which may adversely impact the Fund.

If preferred shares are issued, the Fund may, to the extent possible, purchase or redeem preferred shares from time to time to the extent necessary in order to maintain asset coverage of any preferred shares of at least 200%. In addition, as a condition to obtaining ratings on the preferred shares, the terms of any preferred shares issued are expected to include asset coverage maintenance provisions which will require the redemption of the preferred shares in the event of non-compliance by the Fund and may also prohibit dividends and other distributions on the common shares in such circumstances. In order to meet redemption requirements, the Fund may have to liquidate portfolio securities. Such liquidations and redemptions would cause the Fund to incur related transaction costs and could result in capital losses to the Fund. Prohibitions on dividends and other distributions on the common shares could impair the Fund’s ability to qualify as a RIC under the Code. If the Fund has preferred shares outstanding, two of the Directors will be elected by the holders of preferred shares voting separately as a class. The remaining Directors will be elected by holders of common shares and preferred shares voting together as a single class. In the event the Fund failed to pay dividends on preferred shares for two years, holders of preferred shares would be entitled to elect a majority of the Directors.

If the Fund issues preferred shares, the Fund expects that it will be subject to certain restrictions imposed by guidelines of one or more rating agencies that may issue ratings for preferred shares issued by the Fund. These guidelines are expected to 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 Advisor from managing the Fund’s portfolio in accordance with the Fund’s investment objective and policies.

The Fund may enter into derivative transactions that have economic leverage embedded in them. Derivative transactions that the Fund may enter into and the risks associated with them are described elsewhere in this Prospectus and are also referred to as “Strategic Transactions.” The Fund cannot assure you that investments in derivative transactions that have economic leverage embedded in them will result in a higher return on its common shares.

To the extent the terms of such transactions obligate the Fund to make payments, the Fund may earmark or segregate cash or liquid assets in an amount at least equal to the current value of the amount then payable by the Fund under the terms of such transactions or otherwise cover such transactions in accordance with applicable interpretations of the staff of the SEC. If the current value of the amount then payable by the Fund under the terms of such transactions is represented by the notional amounts of such investments, the Fund would segregate or earmark cash or liquid assets having a market value at least equal to such notional amounts, and if the current value of the amount then payable by the Fund under the terms of such transactions is represented by the market value of the Fund’s current obligations, the Fund would segregate or earmark cash or liquid assets having a market value at least equal to such current obligations. To the extent the terms of such transactions obligate the Fund to deliver particular securities to extinguish the Fund’s obligations under such transactions the Fund may “cover” its obligations under such transactions by either (i) owning the securities or collateral underlying such transactions or (ii) having an absolute and immediate right to acquire such securities or collateral without additional cash consideration (or, if additional cash consideration is required, having earmarked or segregated an appropriate amount of cash or liquid assets). Such earmarking, segregation or cover is intended to provide the Fund with available assets to satisfy its obligations under such transactions. As a result of such earmarking, segregation or cover, the Fund’s obligations under such transactions will not be considered senior securities representing indebtedness for purposes of the Investment Company Act, or considered borrowings subject to the Fund’s limitations on borrowings discussed above, but may create leverage for the Fund. To the extent that the Fund’s obligations under such transactions are not so earmarked, segregated or covered, such obligations may be considered “senior securities representing indebtedness” under the Investment Company Act and therefore subject to the 300% asset coverage requirement.

These earmarking, segregation or cover requirements can result in the Fund maintaining securities positions it would otherwise liquidate, segregating or earmarking assets at a time when it might be disadvantageous to do so or otherwise restrict portfolio management.

The Fund may also borrow money as a temporary measure for extraordinary or emergency purposes, including the payment of dividends and the settlement of securities transactions which otherwise might require untimely dispositions of Fund securities.

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 more fully described below.

Fixed-income securities in which the Fund may invest are generally subject to the following risks:

securities will increase as interest rates fall and decrease as interest rates rise. The Fund may be subject to a greater risk of rising interest rates due to the current period of historically low interest rates. The U.S. Federal Reserve recently increased the federal funds rate and has indicated that it may raise the federal funds rate further and tighten the monetary supply in the near future. Therefore, there is a risk that interest rates will rise, which will likely drive down prices of bonds and other fixed-income securities. The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund’s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund’s NAV. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by the Advisor. To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-related securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the NAV of the Fund to the extent that it invests in floating rate debt securities. These basic principles of bond prices also apply to U.S. Government securities. A security backed by the “full faith and credit” of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change.

The Fund’s use of leverage, as described above under “Leverage,” will tend to increase the Fund’s interest rate risk. The Fund may utilize certain strategies, including taking positions in futures or interest rate swaps, for the purpose of reducing the interest rate sensitivity of fixed-income securities held by the Fund and decreasing the Fund’s exposure to interest rate risk. The Fund is not required to hedge its exposure to interest rate risk and may choose not to do so. In addition, there is no assurance that any attempts by the Fund to reduce interest rate risk will be successful or that any hedges that the Fund may establish will perfectly correlate with movements in interest rates.

Credit Risk. Credit risk is the risk that one or more fixed-income securities in the Fund’s portfolio will decline in price or fail to pay interest or principal when due because the issuer of the security experiences a decline in its financial status. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates. To the extent the Fund invests in below investment grade securities, it will be exposed to a greater amount of credit risk than a fund that only invests in investment grade securities. See “—Below Investment Grade Securities Risk.” In addition, to the extent the Fund uses credit derivatives, such use will expose it to additional risk in the event that the bonds underlying the derivatives default. The degree of credit risk depends on the issuer’s financial condition and on the terms of the securities.

Duration and Maturity Risk. The Advisor may seek to adjust the portfolio’s duration or maturity based on its assessment of current and projected market conditions and all factors that the Advisor deems relevant. In comparison to maturity (which is the date on which the issuer of a debt instrument is obligated to repay the principal amount), duration is a measure of the price volatility of a debt instrument as a result in changes in market rates of interest, based on the weighted average timing of the instrument’s expected principal and interest payments. Specifically, duration measures the anticipated percentage change in NAV that is expected for every percentage point change in interest rates. The two have an inverse relationship. Duration can be a useful tool to estimate anticipated price changes to a fixed pool of income securities associated with changes in interest rates. For example, a duration of five years means that a 1% decrease in interest rates will increase the NAV of the portfolio by approximately 5%; if interest rates increase by 1%, the NAV will decrease by 5%. However, in a managed portfolio of fixed-income securities having differing interest or dividend rates or payment schedules, maturities, redemption provisions, call or prepayment provisions and credit qualities, actual price changes in response to changes in interest rates may differ significantly from a duration-based estimate at any given time. Actual price movements experienced by a portfolio of fixed-income securities will be affected by how interest rates move (i.e., changes in the relationship of long-term interest rates to short-term interest rates and in the relationship of interest rates for highly rated securities and rates for below investment grade securities), the magnitude of any move in interest rates, actual and anticipated prepayments of principal through call or redemption features, the extension of maturities through restructuring, the sale of securities for portfolio management purposes, the reinvestment of proceeds from prepayments on and from sales of securities, and credit quality-related considerations whether associated with financing costs to lower credit quality borrowers or otherwise, as well as other factors. Accordingly, while duration maybe a useful tool to estimate potential price movements in relation to changes in interest rates, investors are cautioned that duration alone will not predict actual changes in the net asset or market value of the Fund’s shares and that actual price movements in the Fund’s portfolio may differ significantly from duration-based estimates. Duration differs from maturity in that it takes into account a security’s yield, coupon payments and its principal payments in addition to the amount of time until the security finally matures. As the value of a security changes over time, so will its duration. Prices of securities with longer durations tend to be more sensitive to interest rate changes than securities with shorter durations. In general, a portfolio of securities with a longer duration can be expected to be more sensitive to interest rate changes than a portfolio with a shorter duration. Any decisions as to the targeted duration or maturity of any particular category of investments or of the Fund’s portfolio generally will be made based on all pertinent market factors at any given time. The Fund may incur costs in seeking to adjust the portfolio’s average duration or maturity. There can be no assurance that the Advisor’s assessment of current and projected market conditions will be correct or that any strategy to adjust the portfolio’s duration or maturity will be successful at any given time.

Nonpayment Risk. Municipal Bonds, like other debt obligations, are subject to the risk of nonpayment. The ability of issuers of municipal securities to make timely payments of interest and principal may be adversely impacted in general economic downturns and as relative governmental cost burdens are allocated and reallocated among federal, state and local governmental units. Such nonpayment would result in a reduction of income to the Fund and could result in a reduction in the value of the municipal security experiencing nonpayment and a potential decrease in the NAV of the Fund.

Economic exposure to the municipal securities market involves certain risks. The Fund’s economic exposure to municipal securities includes municipal securities in the Fund’s portfolio and municipal securities to which the Fund is exposed through the ownership of TOB Residuals. The municipal market is one in which dealer firms make markets in bonds on a principal basis using their proprietary capital, and during the financial crisis of 2007-2009 these firms’ capital was severely constrained. As a result, some firms were unwilling to commit their capital to purchase and to serve as a dealer for municipal securities. Certain municipal securities may not be registered with the SEC or any state securities commission and will not be listed on any national securities exchange. The amount of public information available about the municipal securities to which the Fund is economically exposed is generally less than that for corporate equities or bonds, and the investment performance of the Fund may therefore be more dependent on the analytical abilities of the Advisor than would be a fund investing solely in stocks or taxable bonds. The secondary market for municipal securities, particularly the below investment grade securities to which the Fund may be economically exposed, also tends to be less well-developed or liquid than many other securities markets, which may adversely affect the Fund’s ability to sell such securities at attractive prices or at prices approximating those at which the Fund currently values them.

In addition, many state and municipal governments that issue securities are under significant economic and financial stress and may not be able to satisfy their obligations. The ability of municipal issuers to make timely payments of interest and principal may be diminished during general economic downturns and as governmental cost burdens are reallocated among federal, state and local governments. The taxing power of any governmental entity may be limited by provisions of state constitutions or laws and an entity’s credit will depend on many factors, including the entity’s tax base, the extent to which the entity relies on federal or state aid, and other factors which are beyond the entity’s control. In addition, laws enacted in the future by Congress or state legislatures or referenda could extend the time for payment of principal and/or interest, or impose other constraints on enforcement of such obligations or on the ability of municipalities to levy taxes. Issuers of municipal securities might seek protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, holders of municipal securities could experience delays in collecting principal and interest and such holders may not, in all circumstances, be able to collect all principal and interest to which they are entitled. To enforce its rights in the event of a default in the payment of interest or repayment of principal, or both, the Fund may take possession of and manage the assets securing the issuer’s obligations on such securities, which may increase the Fund’s operating expenses. Any income derived from the Fund’s ownership or operation of such assets may not be tax-exempt or may fail to generate qualifying income for purposes of the income tests applicable to regulated investment companies.

The risks and special considerations involved in investment in Municipal Bonds vary with the types of instruments being acquired. Investments in Non-Municipal Tax-Exempt Securities may present similar risks, depending on the particular product. Certain instruments in which the Fund may invest may be characterized as derivative instruments. See “The Fund’s Investments—Description of Municipal Bonds” and “The Fund’s Investments—Strategic Transactions—Financial Futures Transactions and Options.”

In making investments, the Fund and the Advisor will rely on the opinion of issuers’ bond counsel and, in the case of derivative securities, sponsors’ counsel, on the tax-exempt status of interest on municipal obligations and payments under tax-exempt derivative securities. Neither the Fund nor the Advisor will independently review the bases for those tax opinions. If any of those tax opinions are ultimately determined to be incorrect or if events occur after the security is acquired that impact the security’s tax-exempt status, the Fund and its shareholders could be subject to substantial tax liabilities. An assertion by the Internal Revenue Service that a portfolio security is not exempt from U.S. federal income tax (contrary to indications from the issuer) could affect the Fund’s and its shareholders’ income tax liability for the current or past years and could create liability for information reporting penalties. In addition, an IRS assertion of taxability may cause the Fund to be ineligible to pay exempt-interest dividends or may impair the liquidity and the fair market value of the securities.

The Fund intends to minimize the payment of taxable income to shareholders by investing in tax-exempt or municipal securities in reliance at the time of purchase on an opinion of bond counsel to the issuer that the interest paid on those securities will be excludable from gross income for U.S. federal income tax purposes. Such securities, however, may be determined to pay, or have paid, taxable income subsequent to the Fund’s acquisition of the securities. In that event, the Internal Revenue Service may demand that the Fund pay U.S. federal income taxes on the affected interest income, and, if the Fund agrees to do so, the Fund’s yield could be adversely affected. In addition, the treatment of dividends previously paid or to be paid by the Fund as “exempt interest dividends” could be adversely affected, subjecting the Fund’s shareholders to increased U.S. federal income tax liabilities. Federal tax legislation may limit the types and volume of bonds the interest on which qualifies for a federal income tax-exemption. As a result, current legislation and legislation that may be enacted in the future may affect the availability of Municipal Bonds for investment by the Fund. In addition, future laws, regulations, rulings or court decisions may cause interest on municipal securities to be subject, directly or indirectly, to U.S. federal income taxation or interest on state municipal securities to be subject to state or local income taxation, or the value of state municipal securities to be subject to state or local intangible personal property tax, or may otherwise prevent the Fund from realizing the full current benefit of the tax-exempt status of such securities. Any such change could also affect the market price of such securities, and thus the value of an investment in the Fund.

The Fund expects that a portion of the interest or income it produces will be includable in alternative minimum taxable income. Exempt interest dividends also are likely to be subject to state and local income taxes. Distributions of any capital gain or other taxable income will be taxable to shareholders. The Fund may not be a suitable investment for investors subject to the federal alternative minimum tax or who would become subject to such tax by investing in the Fund. The Fund’s common shares may not be a suitable investment for investors who are subject to the federal alternative minimum tax or who would become subject to such tax by purchasing common shares. The suitability of an investment in common shares will depend upon a comparison of the after-tax yield likely to be provided from the Fund with that from comparable tax-exempt investments not subject to the alternative minimum tax, and from comparable fully taxable investments, in light of each such investor’s tax position. Special considerations apply to corporate investors.

Insurance guarantees that interest payments on a municipal security will be made on time and that the principal will be repaid when the security matures. Insurance is expected to protect the Fund against losses caused by a municipal security issuer’s failure to make interest and principal payments. However, insurance does not protect the Fund or its shareholders against losses caused by declines in a municipal security’s value. Also, the Fund cannot be certain that any insurance company will make the payments it guarantees. Certain significant

providers of insurance for municipal securities incurred significant losses as a result of exposure to sub-prime mortgages and other lower credit quality investments that experienced defaults or otherwise suffered extreme credit deterioration during the financial crisis of 2007-2009. These losses have reduced the insurers’ capital and called into question their continued ability to perform their obligations under such insurance if they are called upon to do so in the future. While an insured municipal security will typically be deemed to have the rating of its insurer, if the insurer of a municipal security suffers a downgrade in its credit rating or the market discounts the value of the insurance provided by the insurer, the rating of the underlying municipal security will be more relevant and the value of the municipal security would more closely, if not entirely, reflect such rating. The Fund may lose money on its investment if the insurance company does not make payments it guarantees. If a municipal security’s insurer fails to fulfill its obligations or loses its credit rating, the value of the security could drop.

The yields on 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 which 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 Advisor will consider such an event in determining whether the Fund should continue to hold the security.

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 Advisor 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 objective will be more dependent on the Advisor’s credit analysis than would be the case when the Fund invests in rated securities.

The Fund may invest in securities that are rated, at the time of investment, below investment grade quality (rated Ba/BB or below, or judged to be of comparable quality by the Advisor), which are commonly referred to as “high yield” or “junk” bonds and are regarded as predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal when due. The value of high yield, lower quality bonds is affected by the creditworthiness of the issuers of the securities and by general economic and specific industry conditions. Issuers of high yield bonds are not perceived to be as strong financially as those with higher credit ratings. These issuers are more vulnerable to financial setbacks and recession than more creditworthy issuers, which may impair their ability to make interest and principal payments. 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.

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 for 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, below investment grade securities historically have been somewhat less sensitive to interest rate changes than higher quality securities of comparable maturity because credit quality is also a significant factor in the valuation of lower grade securities. On the other hand, an increased rate environment results in increased borrowing costs generally, which may impair the credit quality of low-grade issuers and thus have a more significant effect on the value of some lower grade securities. In addition, the current extraordinary low rate environment has expanded the historic universe of buyers of lower grade securities as traditional investment grade oriented investors have been forced to accept more risk in order to maintain income. As rates rise, these recent entrants to the low-grade securities market may exit the market and reduce demand for lower grade securities, potentially resulting in greater price volatility.

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 Advisor 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 objective will be more dependent on the Advisor’s credit analysis than would be the case when the Fund invests in rated securities.

Because the Fund may purchase securities that are not rated by any rating organization, the Advisor 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 objective will be more dependent on the Advisor’s credit analysis than would be the case when the Fund invests in rated securities.

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.

VRDOs are floating rate securities that combine an interest in a long-term municipal bond with a right to demand payment before maturity from a bank or other financial institution. If the bank or financial institution is unable to pay, the Fund may lose money.

Investments in inverse floaters, TOB Residuals 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, TOB Residuals 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, TOB Residuals 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, TOB Residuals 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.

An investment in the Fund’s common shares is subject to investment risk, including the possible loss of the entire amount that you invest. As with any stock, the price of the Fund’s common shares will fluctuate with market conditions and other factors. If shares are sold, the price received may be more or less than the original investment. Common shares are designed for long-term investors and the Fund should not be treated as a trading vehicle. Shares of closed-end management investment companies frequently trade at a discount from their NAV. This risk is separate and distinct from the risk that the Fund’s NAV could decrease as a result of its investment activities. At any point in time an investment in the Fund’s common shares may be worth less than the original amount invested, even after taking into account distributions paid by the Fund. During periods in which the Fund may use leverage, the Fund’s investment, market discount and certain other risks will be magnified.

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. The Fund may not be able to readily dispose of such investments at prices that approximate those at which the Fund could sell such investments if they were more widely traded and, as a result of such illiquidity, the Fund may have to sell other investments or engage in borrowing transactions if necessary to raise cash to meet its obligations. Limited liquidity can also affect the market price of investments, thereby adversely affecting the Fund’s NAV and ability to make dividend distributions. The financial markets in general, and certain segments of the mortgage-related 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 investments could be sold only at arbitrary prices and with substantial losses. Periods of such market dislocation may occur again at any time. Privately issued debt securities are often of below investment grade quality, frequently are unrated and present many of the same risks as investing in below investment grade public debt securities.

Restricted securities are securities that may not be sold to the public without an effective registration statement under the Securities Act, or that may be sold only in a privately negotiated transaction or pursuant to an

exemption from registration. For example, Rule 144A under the Securities Act provides an exemption from the registration requirements of the Securities Act for the resale of certain restricted securities to qualified institutional buyers, such as the Fund. However, an insufficient number of qualified institutional buyers interested in purchasing the Rule 144A-eligible securities that the Fund holds could affect adversely the marketability of certain Rule 144A securities, and the Fund might be unable to dispose of such securities promptly or at reasonable prices. When registration is required to sell a security, the Fund may be obligated to pay all or part of the registration expenses and considerable time may pass before the Fund is permitted to sell a security under an effective registration statement. If adverse market conditions develop during this period, the Fund might obtain a less favorable price than the price that prevailed when the Fund decided to sell. The Fund may be unable to sell restricted and other illiquid investments at opportune times or prices.

Subject to the limitations set forth in the Investment Company Act and the Fund’s governing documents or as otherwise permitted by the SEC, the Fund may acquire shares in other investment companies, including ETFs or BDCs, some of which may be affiliated investment companies. The market value of the shares of other investment companies may differ from their NAV. As an investor in investment companies, including ETFs or BDCs, the Fund would bear its ratable share of that entity’s expenses, including its investment advisory and administration fees, while continuing to pay its own advisory and administration fees and other expenses (to the extent not offset by the Advisor through waivers). As a result, shareholders will be absorbing duplicate levels of fees with respect to investments in other investment companies, including ETFs or BDCs (to the extent not offset by the Advisor through waivers).

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.

option bond transactions. See “—Tender Option Bond Risk” for details about the risks associated with the Fund’s use of TOB Residuals. The Fund cannot assure you that the use of leverage will result in a higher yield on the common shares. Any leveraging strategy the Fund employs may not be successful.

Leverage involves risks and special considerations for common shareholders, including:

Any decline in the NAV of the Fund’s investments will be borne entirely by the holders of common shares. Therefore, if the market value of the Fund’s portfolio declines, leverage will result in a greater decrease in NAV to the holders of common shares than if the Fund were not leveraged. This greater NAV decrease will also tend to cause a greater decline in the market price for the common shares. While the Fund may from time to time consider reducing any outstanding leverage in response to actual or anticipated changes in interest rates in an effort to mitigate the increased volatility of current income and NAV associated with leverage, there can be no assurance that the Fund will actually reduce any outstanding leverage in the future or that any reduction, if undertaken, will benefit the holders of common shares. Changes in the future direction of interest rates are very difficult to predict accurately. If the Fund were to reduce any outstanding leverage based on a prediction about future changes to interest rates, and that prediction turned out to be incorrect, the reduction in any outstanding leverage would likely operate to reduce the income and/or total returns to holders of common shares relative to the circumstance where the Fund had not reduced any of its outstanding leverage. The Fund may decide that this risk outweighs the likelihood of achieving the desired reduction to volatility in income and share price if the prediction were to turn out to be correct, and determine not to reduce any of its outstanding leverage as described above.

The Fund may invest in the securities of other investment companies. Such investment companies may also be leveraged, and will therefore be subject to the leverage risks described above. This additional leverage may in certain market conditions reduce the NAV of the Fund’s common shares and the returns to the holders of common shares.

The Fund currently leverages its assets through the use of TOB Residuals, which are derivative interests in municipal bonds. The TOB Residuals in which the Fund may invest pay interest or income that, in the opinion of counsel to the issuer of such TOB Residuals, is exempt from regular U.S. federal income tax. No independent

investigation will be made to confirm the tax-exempt status of the interest or income paid by TOB Residuals held by the Fund. There is no assurance that the Fund’s strategy of using TOB Residuals to leverage its assets will be successful.

Although the Fund generally would unwind a TOB transaction rather than try to sell a TOB Residual, if it did try to sell a TOB Residual, its ability to do so would depend on the liquidity of the TOB Residual. TOB Residuals have varying degrees of liquidity based, among other things, upon the liquidity of the underlying securities deposited in the TOB Trust. The market price of TOB Residuals is more volatile than the underlying municipal bonds due to leverage.

the amount owed under the liquidity facility over the liquidation proceeds (the “Liquidation Shortfall”). As a result, if the Fund invests in a recourse TOB Trust, the Fund will bear the risk of loss with respect to any Liquidation Shortfall.

Please see “The Fund’s Investments—Leverage—Tender Option Bond Transactions” for additional information.

Subject to its investment objective and policies, the Fund may invest in repurchase agreements. Repurchase agreements typically involve the acquisition by the Fund of fixed-income 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 fixed-income securities, the Fund follows procedures approved by the 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.

The Fund may purchase securities on a when-issued basis (including on a forward commitment or “TBA” (to be announced) basis) and may purchase or sell securities for delayed delivery. When-issued and delayed delivery transactions occur when securities are purchased or sold by the Fund with payment and delivery taking place in the future to secure an advantageous yield or price. Securities purchased on a when-issued or delayed delivery basis may expose the Fund to counterparty risk of default as well as the risk that securities may experience fluctuations in value prior to their actual delivery. The Fund will not accrue income with respect to a when-issued or delayed delivery security prior to its stated delivery date. Purchasing securities on a when-issued or delayed delivery basis can involve the additional risk that the price or yield available in the market when the delivery takes place may not be as favorable as that obtained in the transaction itself.

The Fund may engage in various Strategic Transactions for duration management and other 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 or to establish a position in the securities markets as a temporary substitute for purchasing particular securities or to enhance income or gain. Derivatives are financial contracts or instruments whose value depends on, or is derived from, the value of an underlying asset, reference rate or index (or relationship between two indices). The Fund also may use derivatives to add leverage to the portfolio and/or to hedge against increases in the Fund’s costs associated with any leverage strategy that it may employ. The use of Strategic Transactions to enhance current income may be particularly speculative.

Strategic Transactions involve risks. The risks associated with Strategic Transactions include (i) the imperfect correlation between the value of such instruments and the underlying assets, (ii) the possible default of the counterparty to the transaction, (iii) illiquidity of the derivative instruments, and (iv) high volatility losses caused by unanticipated market movements, which are potentially unlimited. Although both OTC and exchange-traded derivatives markets may experience a lack of liquidity, OTC non-standardized derivative transactions are generally less liquid than exchange-traded instruments. The illiquidity of the derivatives markets may be due to various factors, including congestion, disorderly markets, limitations on deliverable supplies, the participation of speculators, government regulation and intervention, and technical and operational or system failures. In addition, daily limits on price fluctuations and speculative position limits on exchanges on which the Fund may conduct its transactions in derivative instruments may prevent prompt liquidation of positions, subjecting the Fund to the potential of greater losses. Furthermore, the Fund’s ability to successfully use Strategic Transactions depends on the Advisor’s ability to predict pertinent securities prices, interest rates, currency exchange rates and other economic factors, 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. Additionally, segregated or earmarked liquid assets, amounts paid by the Fund as premiums and cash or other assets held in margin accounts with respect to Strategic Transactions are not otherwise available to the Fund for investment purposes. Please see the Fund’s SAI for a more detailed description of Strategic Transactions and the various derivative instruments the Fund may use and the various risks associated with them.

differences can result in an overstatement of the Fund’s NAV and may materially adversely affect the Fund in situations in which the Fund is required to sell derivative instruments. Exchange-traded derivatives and OTC derivative transactions submitted for clearing through a central counterparty have become subject to minimum initial and variation margin requirements set by the relevant clearinghouse, as well as possible margin requirements mandated by the SEC or the CFTC. The SEC, CFTC and federal banking regulators also have imposed margin requirements on certain non-cleared OTC derivatives. As applicable, margin requirements will increase the overall cost for the Fund.

While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund’s hedging transactions will be effective.

Derivatives may give rise to a form of leverage and may expose the Fund to greater risk and increase its costs. Recent legislation calls for new regulation of the derivatives markets. The extent and impact of the regulation is not yet known and may not be known for some time. New regulation may make derivatives more costly, may limit the availability of derivatives, or may otherwise adversely affect the value or performance of derivatives.

The Fund will be subject to credit risk with respect to the counterparties to the derivative contracts purchased by the Fund. Because derivative transactions in which the Fund may engage may involve instruments that are not traded on an exchange or cleared through a central counterparty but are instead traded between counterparties based on contractual relationships, the Fund is subject to the risk that a counterparty will not perform its obligations under the related contracts. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Fund may experience significant delays in obtaining any recovery in bankruptcy or other reorganization proceedings. The Fund may obtain only a limited recovery, or may obtain no recovery, in such circumstances. Although the Fund intends to enter into transactions only with counterparties that the Advisor believes to be creditworthy, there can be no assurance that, as a result, a counterparty will not default and that the Fund will not sustain a loss on a transaction. In the event of the counterparty’s bankruptcy or insolvency, the Fund’s collateral may be subject to the conflicting claims of the counterparty’s creditors, and the Fund may be exposed to the risk of a court treating the Fund as a general unsecured creditor of the counterparty, rather than as the owner of the collateral.

The counterparty risk for cleared derivatives is generally lower than for uncleared OTC derivative transactions since generally a clearing organization becomes substituted for each counterparty to a cleared derivative contract and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing organization for performance of financial obligations under the derivative contract. However, there can be no assurance that a clearing organization, or its members, will satisfy its obligations 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. In addition, cleared derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. Uncleared OTC derivative transactions generally do not benefit from such protections. This exposes the Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss. Such “counterparty risk” is accentuated for contracts with longer maturities where events may intervene to prevent settlement, or where the Fund has concentrated its transactions with a single or small group of counterparties.

In addition, the Fund is subject to the risk that issuers of the instruments in which it invests and trades may default on their obligations under those instruments, and that certain events may occur that have an immediate and significant adverse effect on the value of those instruments. There can be no assurance that an issuer of an

instrument in which the Fund invests will not default, or that an event that has an immediate and significant adverse effect on the value of an instrument will not occur, and that the Fund will not sustain a loss on a transaction as a result.

Swaps are a type of derivative. Swap agreements involve the risk that the party with which the Fund has entered into the swap will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to pay the other party to the agreement. In order to seek to hedge the value of the Fund’s portfolio, to hedge against increases in the Fund’s cost associated with interest payments on any outstanding borrowings or to seek to increase the Fund’s return, the Fund may enter into swaps, including interest rate swap and/or credit default swap transactions. In interest rate swap transactions, there is a risk that yields will move in the direction opposite of the direction anticipated by the Fund, which would cause the Fund to make payments to its counterparty in the transaction that could adversely affect Fund performance. In addition to the risks applicable to swaps generally (including counterparty risk, high volatility, liquidity risk and credit risk), credit default swap transactions involve special risks because they are difficult to value, are highly susceptible to liquidity and credit risk, and generally pay a return to the party that has paid the premium only in the event of an actual default by the issuer of the underlying obligation (as opposed to a credit downgrade or other indication of financial difficulty).

Historically, swap transactions have been individually negotiated non-standardized transactions entered into in OTC markets and have not been subject to the same type of government regulation as exchange-traded instruments. However, since the global financial crisis, the OTC derivatives markets have recently become subject to comprehensive statutes and regulations. In particular, in the United States, the Dodd-Frank Act requires that certain derivatives with U.S. persons must be executed on a regulated market and a substantial portion of OTC derivatives must be submitted for clearing to regulated clearinghouses. As a result, swap transactions entered into by the Fund may become subject to various requirements applicable to swaps under the Dodd-Frank Act, including clearing, exchange-execution, reporting and recordkeeping requirements, which may make it more difficult and costly for the Fund to enter into swap transactions and may also render certain strategies in which the Fund might otherwise engage impossible or so costly that they will no longer be economical to implement. Furthermore, the number of counterparties that may be willing to enter into swap transactions with the Fund may also be limited if the swap transactions with the Fund are subject to the swap regulation under the Dodd-Frank Act.

Credit default swap agreements may effectively add leverage to the Fund’s portfolio because, in addition to its managed assets, the Fund would be subject to investment exposure on the notional amount of the swap. The Fund is not required to enter into swap transactions for hedging purposes or to enhance income or gain and may choose not to do so. In addition, the swaps market is subject to a changing regulatory environment. It is possible that regulatory or other developments in the swaps market could adversely affect the Fund’s ability to successfully use swaps.

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), and credit, legal, counterparty and market risk. 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 generally not be tax-exempt income.

Short-selling involves selling securities which may or may not be owned and borrowing the same securities for delivery to the purchaser, with an obligation to replace the borrowed securities at a later date. 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 capital gain. Any gain will be decreased, and any loss will be increased, by the transaction costs incurred by the Fund, including the costs associated with providing collateral to the broker-dealer (usually cash and liquid securities) and the maintenance of collateral with its custodian. Although the Fund’s gain is limited to the price at which it sold the security short, its potential loss is theoretically unlimited.

Short-selling necessarily involves certain additional risks. However, if the short seller does not own the securities sold short (an uncovered short sale), the borrowed securities must be replaced by securities purchased at market prices in order to close out the short position, and any appreciation in the price of the borrowed securities would result in a loss. Uncovered short sales expose the Fund to the risk of uncapped losses until a position can be closed out due to the lack of an upper limit on the price to which a security may rise. Purchasing securities to close out the short position can itself cause the price of the securities to rise further, thereby exacerbating the loss. There is the risk that the securities borrowed by the Fund in connection with a short-sale must be returned to the securities lender on short notice. If a request for return of borrowed securities occurs at a time when other short-sellers of the security are receiving similar requests, a “short squeeze” can occur, and the Fund may be compelled to replace borrowed securities previously sold short with purchases on the open market at the most disadvantageous time, possibly at prices significantly in excess of the proceeds received at the time the securities were originally sold short.

Inflation risk is the risk that the value of assets or income from investment will be worth less in the future, as inflation decreases the value of money. As inflation increases, the real value of the 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 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.

Market risk is the possibility that the market values of securities owned by the Fund will decline. There is a risk that bond markets will go down in value, including the possibility that such markets will go down sharply and unpredictably.

The prices of fixed-income securities tend to fall as interest rates rise, and such declines tend to be greater among fixed-income securities with longer maturities. Market risk is often greater among certain types of fixed-income securities, such as zero-coupon bonds that do not make regular interest payments but are instead bought at a discount to their face values and paid in full upon maturity. As interest rates change, these securities often fluctuate more in price than securities that make regular interest payments and therefore subject the Fund to greater market risk than a fund that does not own these types of securities.

When-issued and delayed delivery transactions are subject to changes in market conditions from the time of the commitment until settlement, which may adversely affect the prices or yields of the securities being purchased. The greater the Fund’s outstanding commitments for these securities, the greater the Fund’s exposure to market price fluctuations.

Selection risk is the risk that the securities that the Fund’s management selects will underperform the bond market, the market relevant indices or other funds with similar investment objective and investment strategies.

The global financial crisis that began in 2008 caused a significant decline in the value and liquidity of many securities and unprecedented volatility in the markets. Periods of market volatility remain, and may continue to occur in the future, in response to various political, social and economic events both within and outside of the United States. These conditions have resulted in, and in many cases continue to result in, greater price volatility, less liquidity, widening credit spreads and a lack of price transparency, with many securities remaining illiquid and of uncertain value. Such market conditions may adversely affect the Fund, including by making valuation of some of the Fund’s securities uncertain and/or result in sudden and significant valuation increases or declines in the Fund’s holdings. If there is a significant decline in the value of the Fund’s portfolio, this may impact the asset coverage levels for any outstanding leverage the Fund may have.

The Fund’s investments and payment obligations may be based on floating rates, such as London Interbank Offered Rate (“LIBOR”), European Interbank Offer Rate (“EURIBOR”), Sterling Overnight Interbank Average Rate (“SONIA”), and other similar types of reference rates (“Reference Rates”). The elimination of a Reference Rate or any other changes or reforms to the determination or supervision of Reference Rates could have an adverse impact on the market for, or value of, any securities or payments linked to those Reference Rates. In addition, any substitute Reference Rate and any pricing adjustments imposed by a regulator or by counterparties or otherwise may adversely affect the Fund’s performance and/or NAV.

In 2017, the Alternative Reference Rates Committee, a group of large U.S. banks working with the Federal Reserve, announced its selection of the Secured Overnight Financing Rate (“SOFR”), which is intended to be a

broad measure of secured overnight U.S. Treasury repo rates, as an appropriate replacement for LIBOR. The Federal Reserve Bank of New York began publishing the SOFR in 2018, with the expectation that it could be used on a voluntary basis in new instruments and transactions. Bank working groups and regulators in other countries have suggested other alternatives for their markets, including the SONIA in England.

In 2017, the head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. There remains uncertainty regarding the future utilization of LIBOR and the nature of any replacement Reference Rate. As such, the potential effect of a transition away from LIBOR on the Fund or the financial instruments in which the Fund invests cannot yet be determined.

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, ongoing epidemics of infectious diseases in certain parts of the world, terrorist attacks in the United States and around the world, social and political discord, debt crises (such as the Greek crisis), sovereign debt downgrades, increasingly strained relations between the United States and a number of foreign countries, including traditional allies, such as certain European countries, and 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 EU or the EMU, 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.

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

The decision made in Brexit to leave the EU has led to volatility in the financial markets of the United Kingdom and more broadly across Europe and may also lead to weakening in consumer, corporate and financial confidence in such markets. The formal notification to the European Council required under Article 50 of the Treaty on EU was made on March 29, 2017, triggering a two year period during which the terms of exit were negotiated. Pursuant to an agreement between the United Kingdom and the EU, the United Kingdom left the EU on January 31, 2020 subject to a transitional period ending December 31, 2020. The longer term economic, legal, political and social framework to be put in place between the United Kingdom and the EU are unclear at this stage and are likely to lead to ongoing political and economic uncertainty and periods of exacerbated volatility in both the United Kingdom and in wider European markets for some time. In particular, the decision made in 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. This mid- to long-term uncertainty may have an adverse effect on the economy generally and on the ability of the Fund to execute its strategies and to receive attractive returns. 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, for the Fund to execute prudent currency hedging policies. Potential decline in the value of the British Pound and/or the Euro against other currencies, along with the potential downgrading of the United Kingdom’s sovereign credit rating, may also have an impact on the performance of portfolio companies or investments located in the United Kingdom 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.

The global financial crisis led the U.S. Government and the Federal Reserve, as well as certain foreign governments, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that experienced extreme volatility. The withdrawal of Federal Reserve or other U.S. or non-U.S. governmental support could negatively affect financial markets generally and reduce the value and liquidity of certain securities. Additionally, with continued economic recovery and the cessation of certain market support activities, the Fund may face a heightened level of interest rate risk as a result of a rise or increased volatility in interest rates.

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. 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 objective.

In the aftermath of the global financial crisis, there appears to be a renewed 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 objective.

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 changes could occur that may have material adverse effects on the Fund. For example, the regulatory and tax environment for derivative instruments in which the Fund may participate is evolving, and such changes in the regulation or taxation of derivative instruments may have material adverse effects on the value of derivative instruments held by the Fund and the ability of the Fund to pursue its investment strategies.

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 current presidential administration has called for, and in certain instances has begun to implement, 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. Some particular areas identified as subject to potential change, amendment or repeal include the Dodd-Frank Act, including the Volcker Rule and various swaps and derivatives regulations, credit risk retention requirements and the authorities of the Federal Reserve, the Financial Stability Oversight Council and the SEC. 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 risks and uncertainties associated with these policy proposals are heightened by the 2018 U.S. federal election, which has resulted in different political parties controlling the U.S. House of Representatives, on the one hand, and the U.S. Senate and the Executive Branch, on the other hand. Additional risks arising from the differences in expressed policy preferences among the various constituencies in these branches of the U.S. government has led in the past, and may lead in the future, to short term or prolonged policy impasses, which

could, and has, resulted in shutdowns of the U.S. federal government. U.S. federal government shutdowns, especially prolonged shutdowns, could have a significant adverse impact on the economy in general and could impair the ability of issuers to raise capital in the securities markets. Any of these effects could have an adverse impact on companies in the Fund’s portfolio and consequently on the value of their securities and the Fund’s NAV.

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.

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.

At any time after the date of this Prospectus, legislation may be enacted that could negatively affect the assets of the Fund. Legislation or regulation may change the way in which the Fund itself is regulated. The Advisor cannot predict the effects of any new governmental regulation that may be implemented and there can be no assurance that any new governmental regulation will not adversely affect the Fund’s ability to achieve its investment objective.

The investment activities of BlackRock, Inc. (“BlackRock”), the ultimate parent company of the Advisor, and its Affiliates, The PNC Financial Services Group, Inc. (which, through a subsidiary, has a significant economic interest in BlackRock) and its subsidiaries (each with The PNC Financial Services Group, Inc., an “Entity” and collectively, the “Entities”), 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, its Affiliates and the Entities 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, its Affiliates and the Entities intend to engage in such activities and may receive compensation from third parties for their services. None of BlackRock, its Affiliates or the Entities are under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, BlackRock, its Affiliates and the Entities 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 Entity or another account managed by an Affiliate or an Entity and it is possible that the Fund could sustain losses during periods in which one or more Affiliates, Entities 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 interests. 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.

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 objective. 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.

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 Advisor, subject to oversight by the Board.

The Fund is subject to management risk because it is an actively managed investment portfolio. The Advisor 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.

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 Advisor 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 investments may be difficult to value. See “Net Asset Value.” When market quotations are not available, the Advisor 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 it investments and the calculation of the Fund’s NAV.

When market quotations are not readily available or are deemed to be inaccurate or unreliable, the Fund values its investments at fair value as determined in good faith pursuant to policies and procedures approved by the Board. Fair value is defined as the amount for which assets could be sold in an orderly disposition over a reasonable period of time, taking into account the nature of the asset. 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.

Because of overall size, duration and maturities of positions held by the Fund, the value at which its investments can be liquidated may differ, sometimes significantly, from the interim valuations obtained by the Fund. In addition, the timing of liquidations may also affect the values obtained on liquidation. Securities held by the Fund may routinely trade with bid-offer spreads that may be significant. There can be no guarantee that the

Fund’s investments could ultimately be realized at the Fund’s valuation of such investments. In addition, the Fund’s compliance with the asset diversification tests applicable to regulated investment companies depends on the fair market values of the Fund’s assets, and, accordingly, a challenge to the valuations ascribed by the Fund could affect its ability to comply with those tests or require it to pay penalty taxes in order to cure a violation thereof.

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

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

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.

The Fund is dependent on the Advisor for certain management services as well as back-office functions. The Advisor depends 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 Advisor’s 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 Advisor to process trades in a timely fashion could prejudice the investment performance of the Fund.

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 Advisor 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 or misrepresentations by employees of the 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 Advisor’s due diligence efforts, misconduct and intentional misrepresentations may be undetected or not fully comprehended, thereby potentially undermining the Advisor’s due diligence efforts. As a result, no assurances can be given that the due diligence performed by the Advisor will identify or prevent any such misconduct.

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.

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.

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 in the Charter and Bylaws.”

The Fund has adopted certain investment limitations designed to limit investment risk. Some of these limitations are fundamental and thus may not be changed without the approval of the holders of a majority of the outstanding common shares. See “Investment Objective and Policies—Investment Restrictions” in the SAI.

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

Management of Investment Portfolio and Capital Structure to Limit Leverage Risk

The Fund may take certain actions if short-term interest rates increase or market conditions otherwise change (or the Fund anticipates such an increase or change) and any leverage the Fund may have outstanding begins (or is expected) to adversely affect common shareholders. In order to attempt to offset such a negative impact of any outstanding leverage on common shareholders, the Fund may shorten the average maturity of its investment portfolio (by investing in short-term securities) or may reduce any indebtedness that it may have incurred. As explained above under “Risks—Leverage Risk,” the success of any such attempt to limit leverage risk depends on the Advisor’s ability to accurately predict interest rate or other market changes. Because of the difficulty of making such predictions, the Fund may never attempt to manage its capital structure in the manner described in this paragraph.

If market conditions suggest that employing leverage, or employing additional leverage if the Fund already has outstanding leverage, would be beneficial, the Fund may enter into one or more credit facilities, increase any existing credit facilities, sell preferred shares or engage in additional leverage transactions, subject to the restrictions of the Investment Company Act.

The Fund may use certain Strategic Transactions designed to limit the risk of price fluctuations of securities and to preserve capital. These Strategic Transactions include using swaps, financial futures contracts, options on financial futures or options based on either an index of long-term securities, or on securities whose prices, in the opinion of the Advisor, correlate with the prices of the Fund’s investments. There can be no assurance that Strategic Transactions will be used or used effectively to limit risk, and Strategic Transactions may be subject to their own risks.

The Board is responsible for the overall management of the Fund, including supervision of the duties performed by the Advisor. There are eleven Directors. A majority of the Directors are Independent Directors of the Fund. The name and business address of the Directors and officers of the Fund and their principal occupations and other affiliations during the past five years are set forth under “Management of the Fund” in the SAI.

The Advisor is responsible for the management of the Fund’s portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operation of the Fund. The Advisor, located at 100 Bellevue Parkway, Wilmington, Delaware 19809, is a wholly-owned subsidiary of BlackRock.

BlackRock is one of the world’s largest publicly-traded investment management firms. As of [●], 2019, BlackRock’s assets under management were approximately $[●]. BlackRock has over 30 years of experience managing closed-end products and, as of [●], 2019, advised a registered closed-end family of [69] exchange-listed active funds with approximately $[●] in assets.

BlackRock is independent in ownership and governance, with no single majority shareholder and a majority of independent directors. PNC Financial Services Group, Inc. is BlackRock’s largest shareholder.

BlackRock’s investment decision-making process for the municipal security sector is subject to the same discipline, oversight and investment philosophy that the firm applies to other sectors of the fixed-income market.

BlackRock uses a relative value strategy that evaluates the trade-off between risk and return to seek to achieve the Fund’s investment objective. This strategy is combined with disciplined risk control techniques and applied in sector, sub-sector and individual security selection decisions. BlackRock’s extensive personnel and technology resources are the key drivers of the investment philosophy.

The members of the portfolio management team who are primarily responsible for the day-to-day management of the Fund’s portfolio are as follows:

Theodore R. Jaeckel, Jr., Managing Director of BlackRock, Inc., is a member of Americas Fixed-income within Alpha Strategies. He is head portfolio manager on the Municipal Mutual Fund Desk. He is also a member of BlackRock’s Municipal Bond Operating Committee, which oversees all municipal bond portfolio management, research and trading activities. Mr. Jaeckel’s service with BlackRock, Inc. dates back to 1991, including his years with Merrill Lynch Investment Managers (“MLIM”), which merged with BlackRock in 2006. At MLIM, he was a portfolio manager for municipal bond alternative and high yield strategies. Prior to joining MLIM, Mr. Jaeckel was a municipal bond trader with Chemical Bank. Mr. Jaeckel earned a BA degree in history from Hamilton College in 1981.

Walter O’Connor, CFA, Managing Director of BlackRock, Inc., is a member of Americas Fixed-income within Alpha Strategies. He is head Portfolio Manager on the Municipal Mutual Fund Desk. He is also a member of the Municipal Bond Operating Committee, which oversees all municipal bond portfolio management, research and trading activities Mr. O’Connor’s service with BlackRock, Inc. dates back to 1991, including his years with MLIM. At MLIM, he was a portfolio manager for municipal bond retail mutual funds. Prior to joining MLIM, Mr. O’Connor was with Prudential Securities, where he was involved in trading, underwriting, and arbitrage for municipal securities and financial futures. Mr. O’Connor earned a BA degree in finance and philosophy from the University of Notre Dame in 1984.

The SAI provides additional information about other accounts managed by the portfolio management team and the ownership of the Fund’s securities by each portfolio manager.

Pursuant to an investment management agreement between the Advisor and the Fund (the “Investment Management Agreement”), the Fund has agreed to pay the Advisor a monthly management fee at an annual rate equal to 0.55% of the average daily value of the Fund’s Net Assets. “Net Assets” means the total assets of the Fund minus the sum of its accrued liabilities.

A discussion regarding the basis for the approval of the Investment Management Agreement by the Board is available in the Fund’s Semi-Annual Report to shareholders for the period ended October 31, [2018].

Except as otherwise described in this Prospectus, the Fund pays, in addition to the fees paid to the Advisor, all other costs and expenses of its operations, including compensation of its Directors (other than those affiliated with the Advisor), custodian, leveraging expenses, transfer and dividend disbursing agent expenses, legal fees, rating agency fees, listing fees and expenses, expenses of independent auditors, expenses of repurchasing shares, expenses of preparing, printing and distributing shareholder reports, notices, proxy statements and reports to governmental agencies and taxes, if any.

The Fund and the Advisor have entered into 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 ETFs managed by the Advisor or its affiliates that have a contractual fee, through June 30, 2021. In addition, effective December 1, 2019, 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 advised by the Advisor or its affiliates, through June 30, 2021. The Fee Waiver Agreement may be continued from year to year thereafter, provided that such continuance is specifically approved by the Advisor and the Fund (including by a majority of the Fund’s Independent Directors). Neither the Advisor nor the Fund is obligated to extend the Fee Waiver Agreement. 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 Independent Directors or a majority of the outstanding voting securities of the Fund), upon 90 days’ written notice by the Fund to the Advisor.

State Street Bank and Fund Company provides certain administration and accounting services to the Fund pursuant to an Administration and Fund Accounting Services Agreement (the “Administration Agreement”). Pursuant to the Administration Agreement, State Street Bank and Fund Company provides the Fund with, among other things, customary fund accounting services, including computing the Fund’s NAV and maintaining books, records and other documents relating to the Fund’s financial and portfolio transactions, and customary fund administration services, including assisting the Fund with regulatory filings, tax compliance and other oversight activities. For these and other services it provides to the Fund, State Street Bank and Fund Company is paid a monthly fee from the Fund at an annual rate ranging from 0.0075% to 0.015% of the Fund’s Managed Assets, along with an annual fixed fee ranging from $3,000 to $10,000 for the services it provides to the Fund.

The custodian of the assets of the Fund is State Street Bank and Fund Company, whose principal business address is One Lincoln Street, Boston, Massachusetts 02111. The custodian is responsible for, among other things, receipt of and disbursement of funds from the Fund’s accounts, establishment of segregated accounts as necessary, and transfer, exchange and delivery of Fund portfolio securities.

Computershare Fund Company, N.A., whose principal business address is 250 Royall Street, Canton, Massachusetts 02021, serves as the Fund’s transfer agent with respect to the common shares.

[●], whose principal business address is [●], is the independent registered public accounting firm of the Fund and is expected to render an opinion annually on the financial statements of the Fund.

The NAV of the Fund’s common shares will be computed based upon the value of the Fund’s portfolio securities and other assets. NAV per common share will be determined as of the close of the regular trading

session on the NYSE on each business day on which the NYSE is open for trading. The Fund calculates NAV per common share by subtracting the Fund’s liabilities (including accrued expenses, dividends payable and any borrowings of the Fund), and the liquidation value of any outstanding preferred shares of the Fund from the Fund’s total assets (the value of the securities the Fund holds plus cash or other assets, including interest accrued but not yet received) and dividing the result by the total number of common shares of the Fund outstanding.

Fixed-Income Investments. Fixed-income securities for which market quotations are readily available are generally valued using such securities’ current market value. The Fund values fixed-income portfolio securities and non-exchange traded derivatives using the last available bid prices or current market quotations provided by dealers or prices (including evaluated prices) supplied by the Fund’s approved independent third-party pricing services, each in accordance with valuation procedures approved by the Board. The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data (e.g., recent representative bids and offers), credit quality information, perceived market movements, news, and other relevant information and by other methods, which may include consideration of: yields or prices of securities of comparable quality, coupon, maturity and type; indications as to values from dealers; general market conditions; and other factors and assumptions. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but the Fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. The amortized cost method of valuation may be used with respect to debt obligations with sixty days or less remaining to maturity unless the Advisor determines such method does not represent fair value. Loan participation notes are generally valued at the mean of the last available bid prices from one or more brokers or dealers as obtained from independent third-party pricing services. Certain fixed-income investments including asset-backed and mortgage-related securities may be valued based on valuation models that consider the estimated cash flows of each tranche of the entity, establish a benchmark yield and develop an estimated tranche specific spread to the benchmark yield based on the unique attributes of the tranche.

Options, Futures, Swaps and Other Derivatives. Exchange-traded equity options for which market quotations are readily available are valued at the mean of the last bid and ask prices as quoted on the Exchange or the board of trade on which such options are traded. In the event that there is no mean price available for an exchange traded equity option held by the Fund on a day on which the Fund values such option, the last bid (long positions) or ask (short positions) price, if available, will be used as the value of such option. If no bid or ask price is available on a day on which the Fund values such option, the prior day’s price will be used, unless the Advisor determines that such prior day’s price no longer reflects the fair value of the option in which case such option will be treated as a fair value asset. OTC derivatives may be valued using a mathematical model which may incorporate a number of market data factors. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price or settle price as of the close of such exchanges. Swap agreements and other derivatives are generally valued daily based upon quotations from market makers or by a pricing service in accordance with the valuation procedures approved by the Board.

Equity Investments. Equity securities traded on a recognized securities exchange (e.g., NYSE), separate trading boards of a securities exchange or through a market system that provides contemporaneous transaction pricing information (an “Exchange”) are valued via independent pricing services generally at the Exchange closing price or if an Exchange closing price is not available, the last traded price on that Exchange prior to the time as of which the assets or liabilities are valued; however, under certain circumstances other means of determining current market value may be used. If an equity security is traded on more than one Exchange, the current market value of the security where it is primarily traded generally will be used. In the event that there are no sales involving an equity security held by the Fund on a day on which the Fund values such security, the last bid (long positions) or ask (short positions) price, if available, will be used as the value of such security. If the Fund holds both long and short positions in the same security, the last bid price will be applied to securities held long and the last ask price will be applied to securities sold short. If no bid or ask price is available on a day on

which the Fund values such security, the prior day’s price will be used, unless the Advisor determines that such prior day’s price no longer reflects the fair value of the security, in which case such asset would be treated as a fair value asset.

Underlying Funds. Shares of underlying open-end funds are valued at NAV. Shares of underlying exchange-traded closed-end funds or other exchange-traded funds will be valued at their most recent closing price.

General Valuation Information. In determining the market value of portfolio investments, the Fund may employ independent third party pricing services, which may use, without limitation, a matrix or formula method that takes into consideration market indexes, matrices, yield curves and other specific adjustments. This may result in the securities being valued at a price different from the price that would have been determined had the matrix or formula method not been used. All cash, receivables and current payables are carried on the Fund’s books at their face value. The price the Fund could receive upon the sale of any particular portfolio investment may differ from the Fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair valuation methodology or a price provided by an independent pricing service. As a result, the price received upon the sale of an investment may be less than the value ascribed by the Fund, and the Fund could realize a greater than expected loss or lesser than expected gain upon the sale of the investment. The Fund’s ability to value its investment may also be impacted by technological issues and/or errors by pricing services or other third party service providers.

Prices obtained from independent third party pricing services, broker-dealers or market makers to value the Fund’s securities and other assets and liabilities are based on information available at the time the Fund values its assets and liabilities. In the event that a pricing service quotation is revised or updated subsequent to the day on which the Fund valued such security, the revised pricing service quotation generally will be applied prospectively. Such determination shall be made considering pertinent facts and circumstances surrounding such revision.

In the event that application of the methods of valuation discussed above result in a price for a security which is deemed not to be representative of the fair market value of such security, the security will be valued by, under the direction of or in accordance with a method specified by the Board as reflecting fair value. All other assets and liabilities (including securities for which market quotations are not readily available) held by the Fund (including restricted securities) are valued at fair value as determined in good faith by the Board or by the Advisor (its delegate). Any assets and liabilities which are denominated in a foreign currency are translated into U.S. dollars at the prevailing rates of exchange.

Certain of the securities acquired by the Fund may be traded on foreign exchanges or OTC markets on days on which the Fund’s NAV is not calculated and common shares are not traded. In such cases, the NAV of the Fund’s common shares may be significantly affected on days when investors can neither purchase nor sell shares of the Fund.

Fair Value. When market quotations are not readily available or are believed by the Advisor to be unreliable, the Fund’s investments are valued at fair value (“Fair Value Assets”). Fair Value Assets are valued by the Advisor in accordance with procedures approved by the Board. The Advisor may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its complete lack of trading, if the Advisor believes a market quotation from a broker-dealer or other source is unreliable (e.g., where it varies significantly from a recent trade, or no longer reflects the fair value of the security or other asset or liability subsequent to the most recent market quotation), where the security or other asset or liability is only thinly traded or due to the occurrence of a significant event subsequent to the most recent market quotation. For this purpose, a “significant event” is deemed to occur if the Advisor determines, in its business judgment prior to or at the time of pricing the Fund’s assets or liabilities, that it is likely that the event will cause a material change to the last exchange closing price or closing market price of one or more assets or liabilities held by the Fund. On any date the NYSE is open and the primary exchange on which

a foreign asset or liability is traded is closed, such asset or liability will be valued using the prior day’s price, provided that the Advisor is not aware of any significant event or other information that would cause such price to no longer reflect the fair value of the asset or liability, in which case such asset or liability would be treated as a Fair Value Asset. For certain foreign securities, a third-party vendor supplies evaluated, systematic fair value pricing based upon the movement of a proprietary multi-factor model after the relevant foreign markets have closed. This systematic fair value pricing methodology is designed to correlate the prices of foreign securities following the close of the local markets to the price that might have prevailed as of the Fund’s pricing time.

The Advisor, with input from the BlackRock Portfolio Management Group, will submit its recommendations regarding the valuation and/or valuation methodologies for Fair Value Assets to BlackRock’s Valuation Committee. The BlackRock Valuation Committee may accept, modify or reject any recommendations. In addition, the Fund’s accounting agent periodically endeavors to confirm the prices it receives from all third party pricing services, index providers and broker-dealers, and, with the assistance of the Advisor, to regularly evaluate the values assigned to the securities and other assets and liabilities of the Fund. The pricing of all Fair Value Assets is subsequently reported to the Board or a Committee thereof.

When determining the price for a Fair Value Asset, the BlackRock Valuation Committee shall seek to determine the price that the Fund might reasonably expect to receive from the current sale of that asset or liability in an arm’s-length transaction. The price generally may not be determined based on what the Fund might reasonably expect to receive for selling an asset or liability at a later time or if it holds the asset or liability to maturity. Fair value determinations shall be based upon all available factors that the BlackRock Valuation Committee deems relevant at the time of the determination, and may be based on analytical values determined by the Advisor using proprietary or third party valuation models.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of one or more assets or liabilities may not, in retrospect, be the price at which those assets or liabilities could have been sold during the period in which the particular fair values were used in determining the Fund’s NAV. As a result, the Fund’s sale or repurchase of its shares at NAV, at a time when a holding or holdings are valued at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

The Fund’s annual audited financial statements, which are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), follow the requirements for valuation set forth in Financial Accounting Standards Board Accounting Standards Codification Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”), which defines and establishes a framework for measuring fair value under US GAAP and expands financial statement disclosure requirements relating to fair value measurements.

Generally, ASC 820 and other accounting rules applicable to investment companies and various assets in which they invest are evolving. Such changes may adversely affect the Fund. For example, the evolution of rules governing the determination of the fair market value of assets or liabilities to the extent such rules become more stringent would tend to increase the cost and/or reduce the availability of third-party determinations of fair market value.

The tax treatment and characterization of the Fund’s distributions may vary significantly from time to time because of the varied nature of the Fund’s investments. The ultimate tax characterization of the Fund’s distributions made in a fiscal year cannot finally be determined until after the end of that fiscal year. As a result, there is a possibility that the Fund may make total distributions during a fiscal year in an amount that exceeds the Fund’s earnings and profits for U.S. federal income tax purposes. In such situations, the amount by which the Fund’s total distributions exceed earnings and profits would generally be treated as a return of capital reducing the amount of a shareholder’s tax basis in such shareholder’s shares, with any amounts exceeding such basis treated as gain from the sale of shares.

Various factors will affect the level of the Fund’s net investment income, such as its asset mix, its level of retained earnings, the amount of leverage utilized by the Fund and the effects thereof and the movement of interest rates for municipal bonds. To permit the Fund to maintain more stable monthly distributions and to the extent consistent with the distribution requirements imposed on regulated investment companies by the Code, the Fund may from time to time distribute less than the entire amount earned in a particular period. The income would be available to supplement future distributions. As a result, the distributions paid by the Fund for any particular month may be more or less than the amount actually earned by the Fund during that month. Undistributed earnings will increase the Fund’s NAV and, correspondingly, distributions from undistributed earnings and from capital, if any, will reduce the Fund’s NAV.

Unless the registered owner of common shares elects to receive cash by contacting Computershare Fund Company, N.A. (the “Reinvestment Plan Agent”), all dividends or other distributions (together, a “dividend”) declared for your common shares of the Fund will be automatically reinvested by the Reinvestment Plan Agent, as agent for shareholders in administering the Fund’s dividend reinvestment plan (the “Reinvestment Plan”), in additional common shares of the Fund. Shareholders who elect not to participate in the Reinvestment Plan will receive all dividends in cash paid by check mailed directly to the shareholder of record (or, if the common shares are held in street or other nominee name, then to such nominee) by the Reinvestment Plan Agent. You may elect not to participate in the Reinvestment Plan and to receive all dividends in cash by contacting the Reinvestment Plan Agent at the address set forth below. Participation in the Reinvestment Plan is completely voluntary and may be terminated or resumed at any time without penalty by written notice if received and processed by the Reinvestment Plan Agent prior to the dividend record date. Additionally, the Reinvestment Plan Agent seeks to process notices received after the record date but prior to the payable date and such notices often will become effective by the payable date. Where late notices are not processed by the applicable payable date, such termination or resumption will be effective with respect to any subsequently declared dividend.

Some brokers may automatically elect to receive cash on your behalf and may re-invest that cash in additional common shares of the Fund for you. If you wish for all dividends declared on your common shares of the Fund to be automatically reinvested pursuant to the Reinvestment Plan, please contact your broker.

The Reinvestment Plan Agent will open an account for each common shareholder under the Reinvestment Plan in the same name in which such common shareholder’s common shares are registered. Whenever the Fund declares a dividend payable in cash, non-participants in the Reinvestment Plan will receive cash and participants in the Reinvestment Plan will receive the equivalent in common shares. The common shares will be acquired by the Reinvestment Plan Agent for the participants’ accounts, depending upon the circumstances described below, either (i) through receipt of additional unissued but authorized common shares from the Fund (“newly issued

common shares”) or (ii) by purchase of outstanding common shares on the open market (“open-market purchases”). If, on the dividend payment date, the NAV is equal to or less than the market price per share plus estimated brokerage commissions (such condition often referred to as a “market premium”), the Reinvestment Plan Agent will invest the dividend amount in newly issued common shares on behalf of the participants. The number of newly issued common shares to be credited to each participant’s account will be determined by dividing the dollar amount of the dividend by the NAV on the dividend payment date. However, if the NAV is less than 95% of the market price on the dividend payment date, the dollar amount of the dividend will be divided by 95% of the market price on the dividend payment date. If, on the dividend payment date, the NAV is greater than the market price per share plus estimated brokerage commissions (such condition often referred to as a “market discount”), the Reinvestment Plan Agent will invest the dividend amount in common shares acquired on behalf of the participants in open-market purchases. In the event of a market discount on the dividend payment date, the Reinvestment Plan Agent will have until the last business day before the next date on which the common shares trade on an “ex-dividend” basis or 30 days after the dividend payment date, whichever is sooner, to invest the dividend amount in common shares acquired in open-market purchases. It is contemplated that the Fund will pay monthly income dividends. If, before the Reinvestment Plan Agent has completed its open-market purchases, the market price per common share exceeds the NAV per common share, the average per common share purchase price paid by the Reinvestment Plan Agent may exceed the NAV of the common shares, resulting in the acquisition of fewer common shares than if the dividend had been paid in newly issued common shares on the dividend payment date. Because of the foregoing difficulty with respect to open-market purchases, the Reinvestment Plan provides that if the Reinvestment Plan Agent is unable to invest the full dividend amount in open-market purchases, or if the market discount shifts to a market premium during the purchase period, the Reinvestment Plan Agent may cease making open-market purchases and may invest any uninvested portion in newly issued shares. Investments in newly issued shares made in this manner would be made pursuant to the same process described above and the date of issue for such newly issued shares will substitute for the dividend payment date.

The Reinvestment Plan Agent maintains all shareholders’ accounts in the Reinvestment Plan and furnishes written confirmation of all transactions in the accounts, including information needed by shareholders for tax records. Common shares in the account of each Reinvestment Plan participant will be held by the Reinvestment Plan Agent on behalf of the Reinvestment Plan participant, and each shareholder proxy will include those shares purchased or received pursuant to the Reinvestment Plan.

In the case of shareholders such as banks, brokers or nominees, which hold shares for others who are the beneficial owners, the Reinvestment Plan Agent will administer the Reinvestment Plan on the basis of the number of common shares certified from time to time by the record shareholder’s name and held for the account of beneficial owners who participate in the Reinvestment Plan.

The Reinvestment Plan Agent’s fees for the handling of the reinvestment of dividends will be paid by the Fund. However, each participant 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. The automatic reinvestment of dividends will not relieve participants of any U.S. federal, state or local income tax that may be payable (or required to be withheld) on such dividends. See “Tax Matters.”

Participants that request a sale of shares through the Reinvestment Plan Agent are subject to a $2.50 sales fee and a $0.15 per share fee. Per share fees include any applicable brokerage commissions the Reinvestment Plan Agent is required to pay.

The Fund reserves the right to amend or terminate the Reinvestment Plan. There is no direct service charge to participants with regard to purchases in the Reinvestment Plan; however, the Fund reserves the right to amend the Reinvestment Plan to include a service charge payable by the participants. Notice of amendments to the Reinvestment Plan will be sent to participants.

All correspondence concerning the Reinvestment Plan should be directed to the Reinvestment Plan Agent, through the internet at http://www.computershare.com/blackrock, or in writing to Computershare, P.O. Box 505000, Louisville, KY 40233, Telephone: (800) 699-1236. Overnight correspondence should be directed to the Reinvestment Plan Agent at Computershare, 462 South 4th Street, Suite 1600, Louisville, KY 40202.

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:

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.

[The following discussion is a brief summary of certain U.S. federal income tax considerations affecting the Fund and the purchase, ownership and disposition of the Fund’s common shares. A more detailed discussion of the tax rules applicable to the Fund and its common shareholders can be found in the SAI that is incorporated by reference into this Prospectus. Except as otherwise noted, this discussion assumes you are a taxable U.S. holder (as defined below) and that you hold your common shares as capital assets for U.S. federal income tax purposes (generally, assets held for investment). This discussion is based upon current provisions of the Code, the regulations promulgated thereunder and judicial and administrative authorities, all of which are subject to change or differing interpretations by the courts or the Internal Revenue Service, possibly with retroactive effect. No attempt is made to present a detailed explanation of all U.S. federal tax concerns affecting the Fund and its common shareholders. The discussion set forth herein does not constitute tax advice and potential investors are urged to consult their own tax advisers to determine the specific U.S. federal, state, local and foreign tax consequences to them of investing in the Fund.

In addition, no attempt is made to address tax considerations applicable to an investor with a special tax status, such as a financial institution, REIT, insurance company, regulated investment company, individual retirement account, other tax-exempt organization, dealer in securities or currencies, person holding shares of the Fund as part of a hedging, integrated, conversion or straddle transaction, trader in securities that has elected the mark-to-market method of accounting for its securities, U.S. holder (as defined below) whose functional currency is not the U.S. dollar, investor with “applicable financial statements” within the meaning of Section 451(b) of the Code, or non-U.S. investor. Furthermore, this discussion does not reflect possible application of the alternative minimum tax.

A U.S. holder is a beneficial owner that is for U.S. federal income tax purposes:

The Fund has elected to be treated as a RIC under Subchapter M of the Code. In order to qualify as a RIC, the Fund must, among other things, satisfy certain requirements relating to the sources of its income,

diversification of its assets, and distribution of its income to its shareholders. First, the Fund must derive at least 90% of its annual gross income from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock or securities or foreign currencies, or other income (including but not limited to gains from options, futures and forward contracts) derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in “qualified publicly traded partnerships” (as defined in the Code) (the “90% gross income test”). Second, the Fund must diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the value of its total assets consists of cash, cash items, U.S. Government securities, securities of other RICs and other securities, with such other securities limited in respect of any one issuer to an amount not greater in value than 5% of the value of the Fund’s total assets and to not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of the total assets is invested in the securities (other than U.S. Government securities and securities of other RICs) of any one issuer, any two or more issuers controlled by the Fund and engaged in the same, similar or related trades or businesses, or any one or more “qualified publicly traded partnerships.”

As long as the Fund qualifies as a RIC, the Fund will generally not be subject to corporate-level U.S. federal income tax on income and gains that it distributes each taxable year to its shareholders, provided that in such taxable year it distributes at least 90% of the sum of (i) its net tax-exempt interest income, if any, and (ii) its “investment company taxable income” (which includes, among other items, dividends, taxable interest, taxable original issue discount and market discount income, income from securities lending, net short-term capital gain in excess of net long-term capital loss, and any other taxable income other than “net capital gain” (as defined below) and is reduced by deductible expenses) determined without regard to the deduction for dividends paid. The Fund may retain for investment its net capital gain (which consists of the excess of its net long-term capital gain over its net short-term capital loss). However, if the Fund retains any net capital gain or any investment company taxable income, it will be subject to tax at regular corporate rates on the amount retained.

The Code imposes a 4% nondeductible excise tax on the Fund to the extent the Fund does not distribute by the end of any calendar year at least the sum of (i) 98% of its ordinary income (not taking into account any capital gain or loss) for the calendar year and (ii) 98.2% of its capital gain in excess of its capital loss (adjusted for certain ordinary losses) for a one-year period generally ending on October 31 of the calendar year (unless an election is made to use the Fund’s fiscal year). In addition, the minimum amounts that must be distributed in any year to avoid the excise tax will be increased or decreased to reflect any under-distribution or over-distribution, as the case may be, from the previous year. For purposes of the excise tax, the Fund will be deemed to have distributed any income on which it paid U.S. federal income tax. While the Fund intends to distribute any income and capital gain in the manner necessary to minimize imposition of the 4% nondeductible excise tax, there can be no assurance that sufficient amounts of the Fund’s taxable income and capital gain will be distributed to entirely avoid the imposition of the excise tax. In that event, the Fund will be liable for the excise tax only on the amount by which it does not meet the foregoing distribution requirement.

If in any taxable year the Fund should fail to qualify under Subchapter M of the Code for tax treatment as a RIC, the Fund would incur a regular corporate U.S. federal income tax upon all of its taxable income for that year, and all distributions to its shareholders (including distributions of net capital gain) would be taxable to shareholders as ordinary dividend income for U.S. federal income tax purposes to the extent of the Fund’s earnings and profits. Provided that certain holding period and other requirements were met, such dividends would be eligible (i) to be treated as qualified dividend income in the case of shareholders taxed as individuals and (ii) for the dividends received deduction in the case of corporate shareholders. In addition, to qualify again to be taxed as a RIC in a subsequent year, the Fund would be required to distribute to shareholders its earnings and profits attributable to non-RIC years. In addition, if the Fund failed to qualify as a RIC for a period greater than two taxable years, then, in order to qualify as a RIC in a subsequent year, the Fund would be required to elect to recognize and pay tax on any net built-in gain (the excess of aggregate gain, including items of income, over aggregate loss that would have been realized if the Fund had been liquidated) or, alternatively, be subject to taxation on such built-in gain recognized for a period of five years.

The remainder of this discussion assumes that the Fund qualifies for taxation as a RIC.

The Fund’s Investments. Certain of the Fund’s investment practices are subject to special and complex U.S. federal income tax provisions (including mark-to-market, constructive sale, straddle, wash sale, short sale and other rules) that may, among other things, (i) disallow, suspend or otherwise limit the allowance of certain losses or deductions, (ii) convert lower taxed long-term capital gains or qualified dividend income into higher taxed short-term capital gains or ordinary income, (iii) convert ordinary loss or a deduction into capital loss (the deductibility of which is more limited), (iv) cause the Fund to recognize income or gain without a corresponding receipt of cash, (v) adversely affect the time as to when a purchase or sale of stock or securities is deemed to occur, (vi) adversely alter the characterization of certain complex financial transactions and (vii) produce income that will not be “qualified” income for purposes of the 90% annual gross income requirement described above. These U.S. federal income tax provisions could therefore affect the amount, timing and character of distributions to common shareholders. The Fund intends to monitor its transactions and may make certain tax elections and may be required to dispose of securities to mitigate the effect of these provisions and prevent disqualification of the Fund as a RIC. Additionally, the Fund may be required to limit its activities in derivative instruments in order to enable it to maintain its RIC status.

The Fund may invest a portion of its net assets in below investment grade securities. Investments in these types of securities may present special tax issues for the Fund. U.S. federal income tax rules are not entirely clear about issues such as when the Fund may cease to accrue interest, original issue discount or market discount, when and to what extent deductions may be taken for bad debts or worthless securities, how payments received on obligations in default should be allocated between principal and income and whether modifications or exchanges of debt obligations in a bankruptcy or workout context are taxable. These and other issues could affect the Fund’s ability to distribute sufficient income to preserve its status as a RIC or to avoid the imposition of U.S. federal income or excise tax.

Certain debt securities acquired by the Fund may be treated as debt securities that were originally issued at a discount. Generally, the amount of the original issue discount is treated as interest income and is included in taxable income (and required to be distributed by the Fund in order to qualify as a RIC and avoid U.S. federal income tax or the 4% excise tax on undistributed income) over the term of the security, even though payment of that amount is not received until a later time, usually when the debt security matures.

If the Fund purchases a debt security on a secondary market at a price lower than its adjusted issue price, the excess of the adjusted issue price over the purchase price is “market discount.” Unless the Fund makes an election to accrue market discount on a current basis, generally, any gain realized on the disposition of, and any partial payment of principal on, a debt security having market discount is treated as ordinary income to the extent the gain, or principal payment, does not exceed the “accrued market discount” on the debt security. Market discount generally accrues in equal daily installments. If the Fund ultimately collects less on the debt instrument than its purchase price plus the market discount previously included in income, the Fund may not be able to benefit from any offsetting loss deductions.

The Fund may invest in preferred securities or other securities the U.S. federal income tax treatment of which may not be clear or may be subject to recharacterization by the Internal Revenue Service. To the extent the tax treatment of such securities or the income from such securities differs from the tax treatment expected by the Fund, it could affect the timing or character of income recognized by the Fund, potentially requiring the Fund to purchase or sell securities, or otherwise change its portfolio, in order to comply with the tax rules applicable to RICs under the Code.

Gain or loss on the sale of securities by the Fund will generally be long-term capital gain or loss if the securities have been held by the Fund for more than one year. Gain or loss on the sale of securities held for one year or less will be short-term capital gain or loss.

securities of foreign corporations, the Fund may elect for U.S. federal income tax purposes to treat foreign income taxes paid by it as paid by its shareholders. The Fund may qualify for and make this election in some, but not necessarily all, of its taxable years. If the Fund were to make such an election, shareholders would be required to take into account an amount equal to their pro rata portions of such foreign taxes in computing their taxable income and then treat an amount equal to those foreign taxes as a U.S. federal income tax deduction or as a foreign tax credit against their U.S. federal income tax liability. A taxpayer’s ability to use a foreign tax deduction or credit is subject to limitations under the Code. Shortly after any year for which it makes such an election, the Fund will report to its shareholder the amount per share of such foreign income tax that must be included in each shareholder’s gross income and the amount that may be available for the deduction or credit.

Foreign currency gain or loss on foreign currency exchange contracts, non-U.S. dollar-denominated securities contracts, and non-U.S. dollar-denominated futures contracts, options and forward contracts that are not section 1256 contracts (as defined below) generally will be treated as ordinary income and loss.

Income from options on individual securities written by the Fund will not be recognized by the Fund for tax purposes until an option is exercised, lapses or is subject to a “closing transaction” (as defined by applicable regulations) pursuant to which the Fund’s obligations with respect to the option are otherwise terminated. If the option lapses without exercise, the premiums received by the Fund from the writing of such options will generally be characterized as short-term capital gain. If the Fund enters into a closing transaction, the difference between the premiums received and the amount paid by the Fund to close out its position will generally be treated as short-term capital gain or loss. If an option written by the Fund is exercised, thereby requiring the Fund to sell the underlying security, the premium will increase the amount realized upon the sale of the security, and the character of any gain on such sale of the underlying security as short-term or long-term capital gain will depend on the holding period of the Fund in the underlying security. Because the Fund will not have control over the exercise of the options it writes, such exercises or other required sales of the underlying securities may cause the Fund to realize gains or losses at inopportune times.

Index options that qualify as “section 1256 contracts” will generally be “marked-to-market” for U.S. federal income tax purposes. As a result, the Fund will generally recognize gain or loss on the last day of each taxable year equal to the difference between the value of the option on that date and the adjusted basis of the option. The adjusted basis of the option will consequently be increased by such gain or decreased by such loss. Any gain or loss with respect to options on indices and sectors that qualify as “section 1256 contracts” will be treated as short-term capital gain or loss to the extent of 40% of such gain or loss and long-term capital gain or loss to the extent of 60% of such gain or loss. Because the mark-to-market rules may cause the Fund to recognize gain in advance of the receipt of cash, the Fund may be required to dispose of investments in order to meet its distribution requirements. “Mark-to-market” losses may be suspended or otherwise limited if such losses are part of a straddle or similar transaction.

The Fund will either distribute or retain for reinvestment all or part of its net capital gain. If any such gain is retained, the Fund will be subject to a corporate income tax on such retained amount. In that event, the Fund expects to report the retained amount as undistributed capital gain in a notice to its common shareholders, each of whom, if subject to U.S. federal income tax on long-term capital gains, (i) will be required to include in income for U.S. federal income tax purposes as long-term capital gain its share of such undistributed amounts, (ii) will be entitled to credit its proportionate share of the tax paid by the Fund against its U.S. federal income tax liability and to claim refunds to the extent that the credit exceeds such liability and (iii) will increase its basis in its common shares by the amount of undistributed capital gains included in the shareholder’s income less the tax deemed paid by the shareholder under clause (ii).

you have held your common shares. All other dividends paid to you by the Fund (including dividends from net short-term capital gains or tax-exempt interest, if any) from its current or accumulated earnings and profits (“ordinary income dividends”) are generally subject to tax as ordinary income. Provided that certain holding period and other requirements are met, ordinary income dividends (if properly reported by the Fund) may qualify (i) for the dividends received deduction in the case of corporate shareholders to the extent that the Fund’s income consists of dividend income from U.S. corporations, and (ii) in the case of individual shareholders, as “qualified dividend income” eligible to be taxed at long-term capital gains rates to the extent that the Fund receives qualified dividend income. Qualified dividend income is, in general, dividend income from taxable domestic corporations and certain qualified foreign corporations (e.g., generally, foreign corporations incorporated in a possession of the United States or in certain countries with a qualifying comprehensive tax treaty with the United States, or whose stock with respect to which such dividend is paid is readily tradable on an established securities market in the United States). There can be no assurance as to what portion, if any, of the Fund’s distributions will constitute qualified dividend income or be eligible for the dividends received deduction.

Any distributions you receive that are in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital to the extent of your adjusted tax basis in your common shares, and thereafter as capital gain from the sale of common shares. The amount of any Fund distribution that is treated as a return of capital will reduce your adjusted tax basis in your common shares, thereby increasing your potential gain or reducing your potential loss on any subsequent sale or other disposition of your common shares.

Common shareholders may be entitled to offset their capital gain dividends with capital losses. The Code contains a number of statutory provisions affecting when capital losses may be offset against capital gain, and limiting the use of losses from certain investments and activities. Accordingly, common shareholders that have capital losses are urged to consult their tax advisers.

Dividends and other taxable distributions are taxable to you even though they are reinvested in additional common shares of the Fund. Dividends and other distributions paid by the Fund are generally treated under the Code as received by you at the time the dividend or distribution is made. If, however, the Fund pays you a dividend in January that was declared in the previous October, November or December to common shareholders of record on a specified date in one of such months, then such dividend will be treated for U.S. federal income tax purposes as being paid by the Fund and received by you on December 31 of the year in which the dividend was declared. In addition, certain other distributions made after the close of the Fund’s taxable year may be “spilled back” and treated as paid by the Fund (except for purposes of the 4% nondeductible excise tax) during such taxable year. In such case, you will be treated as having received such dividends in the taxable year in which the distributions were actually made.

The price of common shares purchased at any time may reflect the amount of a forthcoming distribution. Those purchasing common shares just prior to the record date of a distribution will receive a distribution which will be taxable to them even though it represents, economically, a return of invested capital.

The Fund will send you information after the end of each year setting forth the amount and tax status of any distributions paid to you by the Fund.

The sale or other disposition of common shares will generally result in capital gain or loss to you and will be long-term capital gain or loss if you have held such common shares for more than one year at the time of sale. Any loss upon the sale or other disposition of common shares held for six months or less will be treated as long-term capital loss to the extent of any capital gain dividends received (including amounts credited as an undistributed capital gain dividend) by you with respect to such common shares. Any loss you recognize on a sale or other disposition of common shares will be disallowed if you acquire other common shares (whether through the automatic reinvestment of dividends or otherwise) within a 61-day period beginning 30 days before and ending 30 days after your sale or exchange of the common shares. In such case, your tax basis in the common shares acquired will be adjusted to reflect the disallowed loss.

If the Fund liquidates, shareholders generally will realize capital gain or loss upon such liquidation in an amount equal to the difference between the amount of cash or other property received by the shareholder (including any property deemed received by reason of its being placed in a liquidating trust) and the shareholder’s adjusted tax basis in its common shares. Any such gain or loss will be long-term if the shareholder is treated as having a holding period in the Fund shares of greater than one year, and otherwise will be short-term.

Current U.S. federal income tax law taxes both long-term and short-term capital gain of corporations at the rates applicable to ordinary income. For non-corporate taxpayers, short-term capital gain is currently taxed at rates applicable to ordinary income while long-term capital gain generally is taxed at a reduced maximum rate. The deductibility of capital losses is subject to limitations under the Code.

Certain U.S. holders who are individuals, estates or trusts and whose income exceeds certain thresholds will be required to pay a 3.8% Medicare tax on all or a portion of their “net investment income,” which includes dividends received from the Fund and capital gains from the sale or other disposition of the Fund’s common shares.

A common shareholder that is a nonresident alien individual or a foreign corporation (a “foreign investor”) generally will be subject to U.S. federal withholding tax at the rate of 30% (or possibly a lower rate provided by an applicable tax treaty) on ordinary income dividends (except as discussed below). In general, U.S. federal withholding tax and U.S. federal income tax will not apply to any gain or income realized by a foreign investor in respect of any distribution of net capital gain (including amounts credited as an undistributed capital gain dividend) or upon the sale or other disposition of common shares of the Fund. Different tax consequences may result if the foreign investor is engaged in a trade or business in the United States or, in the case of an individual, is present in the United States for 183 days or more during a taxable year and certain other conditions are met. Foreign investors should consult their tax advisers regarding the tax consequences of investing in the Fund’s common shares.

Ordinary income dividends properly reported by a RIC are generally exempt from U.S. federal withholding tax where they (i) are paid in respect of the RIC’s “qualified net interest income” (generally, its U.S.-source interest income, other than certain contingent interest and interest from obligations of a corporation or partnership in which the RIC is at least a 10% shareholder, reduced by expenses that are allocable to such income) or (ii) are paid in respect of the RIC’s “qualified short-term capital gains” (generally, the excess of the RIC’s net short-term capital gain over its long-term capital loss for such taxable year). Depending on its circumstances, the Fund may report all, some or none of its potentially eligible dividends as such qualified net interest income or as qualified short-term capital gains, and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding. In order to qualify for this exemption from withholding, a foreign investor needs to comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing an IRS Form W-8BEN, W-8BEN-E or substitute Form). In the case of common shares held through an intermediary, the intermediary may have withheld even if the Fund reported the payment as qualified net interest income or qualified short-term capital gain. Foreign investors should contact their intermediaries with respect to the application of these rules to their accounts. There can be no assurance as to what portion of the Fund’s distributions would qualify for favorable treatment as qualified net interest income or qualified short-term capital gains.

In addition, withholding at a rate of 30% will apply to dividends paid in respect of common shares of the Fund held by or through certain foreign financial institutions (including investment funds), unless such institution enters into an agreement with the Treasury to report, on an annual basis, information with respect to shares in, and accounts maintained by, the institution to the extent such shares or accounts are held by certain U.S. persons and by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments. Accordingly, the entity through which common shares of the Fund are held will affect the determination of whether such withholding is required. Similarly, dividends paid in respect of common shares of the Fund held by an investor that is a non-financial foreign entity that does not qualify under certain exemptions will be subject to withholding at a rate of 30%, unless such entity either (i) certifies that such entity does not have

any “substantial United States owners” or (ii) provides certain information regarding the entity’s “substantial United States owners,” which the Fund or applicable withholding agent will in turn provide to the Secretary of the Treasury. An intergovernmental agreement between the United States and an applicable foreign country, or future Treasury regulations or other guidance, may modify these requirements. The Fund will not pay any additional amounts to common shareholders in respect of any amounts withheld. Foreign investors are encouraged to consult with their tax advisers regarding the possible implications of these rules on their investment in the Fund’s common shares.

U.S. federal backup withholding tax may be required on dividends, distributions and sale proceeds payable to certain non-exempt common shareholders who fail to supply their correct taxpayer identification number (in the case of individuals, generally, their social security number) or to make required certifications, or who are otherwise subject to backup withholding. Backup withholding is not an additional tax and any amount withheld may be refunded or credited against your U.S. federal income tax liability, if any, provided that you timely furnish the required information to the Internal Revenue Service.

Ordinary income dividends, capital gain dividends, and gain from the sale or other disposition of common shares of the Fund also may be subject to state, local, and/or foreign taxes. Common shareholders are urged to consult their own tax advisers regarding specific questions about U.S. federal, state, local or foreign tax consequences to them of investing in the Fund.

The foregoing is a general and abbreviated summary of certain provisions of the Code and the Treasury regulations currently in effect as they directly govern the taxation of the Fund and its common shareholders. These provisions are subject to change by legislative or administrative action, and any such change may be retroactive. A more detailed discussion of the tax rules applicable to the Fund and its common shareholders can be found in the SAI that is incorporated by reference into this Prospectus. Common shareholders are urged to consult their tax advisers regarding specific questions as to U.S. federal, state, local and foreign income or other taxes.

Please refer to the SAI for more detailed information. You are urged to consult your tax adviser.]

[The value of a right will not be includible in the income of a common shareholder at the time the right is issued.

The basis of a right issued to a common shareholder will be zero, and the basis of the share with respect to which the subscription right was issued (the old share) will remain unchanged, unless either (a) the fair market value of the right on the date of distribution is at least 15% of the fair market value of the old share, or (b) such shareholder affirmatively elects (in the manner set out in Treasury regulations under the Code) to allocate to the subscription right a portion of the basis of the old share. If either (a) or (b) applies, then except as described below such shareholder must allocate basis between the old share and the right in proportion to their fair market values on the date of distribution.

The basis of a right purchased in the market will generally be its purchase price.

The holding period of a right issued to a common shareholder will include the holding period of the old share. No gain or loss will be recognized by a common shareholder upon the exercise of a right.

No loss will be recognized by a common shareholder if a right distributed to such common shareholder expires unexercised because the basis of the old share may be allocated to a right only if the right is exercised. If a right that has been purchased in the market expires unexercised, there will be a recognized loss equal to the basis of the right.

Any gain or loss on the sale of a right will be a capital gain or loss if the right is held as a capital asset (which in the case of rights issued to common shareholders will depend on whether the old share of common stock is held as a capital asset), and will be a long-term capital gain or loss if the holding period is deemed to exceed one year.]

[The Fund’s Charter includes provisions that could have the effect of limiting the ability of other entities or persons to acquire control of the Fund or to change the composition of its Board of Directors and could have the effect of depriving common stockholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging a third-party from seeking to obtain control of the Fund. A Director may be removed from office with or without cause but only by vote of the holders of at least 66 2/3% of the shares entitled to vote in an election to fill that directorship.

In addition, the Charter requires the favorable vote of the holders of at least 66 2/3% of the Fund’s shares to approve, adopt or authorize the following:

unless such action has been approved, adopted or authorized by the affirmative vote of at least two-thirds of the total number of Directors fixed in accordance with the Bylaws, in which case the affirmative vote of a majority of the Fund’s shares of capital stock is required.

In addition, conversion of the Fund to an open-end investment company would require an amendment to the Fund’s Charter. The amendment would have to be declared advisable by the Board of Directors prior to its submission to stockholders. Such an amendment would require the favorable vote of the holders of at least 66 2/3% of the Fund’s outstanding shares of capital stock entitled to be voted on the matter, voting as a single class (or a majority of such shares if the amendment was previously approved, adopted or authorized by two-thirds of the total number of Directors fixed in accordance with the Bylaws). Such a vote also would satisfy a separate requirement in the 1940 Act that the change be approved by the stockholders. Shareholders of an open-end investment company may require the company to redeem their common shares at any time (except in certain circumstances as authorized by or under the 1940 Act) at their NAV, less such redemption charge, if any, as might be in effect at the time of a redemption. If the Fund is converted to an open-end investment company, it could be required to liquidate portfolio securities to meet requests for redemption, and the common shares would no longer be listed on a stock exchange.

The Charter and Bylaws provide that the Board of Directors has the power, to the exclusion of stockholders, to make, alter or repeal any of the Bylaws (except for any Bylaw specified not to be amended or repealed by the Board), subject to the requirements of the 1940 Act. Neither this provision of the Charter, nor any of the foregoing provisions of the Charter requiring the affirmative vote of 66 2/3% of shares of capital stock of the Fund, can be amended or repealed except by the vote of such required number of shares.

The Board of Directors has determined that the 66 2/3% voting requirements described above, which are greater than the minimum requirements under Maryland law or the 1940 Act, are in the best interests of stockholders generally. Reference should be made to the Charter on file with the SEC for the full text of these provisions.

The Fund’s Bylaws generally require that advance notice be given to the Fund in the event a stockholder desires to nominate a person for election to the Board of Directors or to transact any other business at an annual meeting of stockholders. Notice of any such nomination or business must be delivered to or received at the principal executive offices of the Fund not less than 120 calendar days nor more than 150 calendar days prior to the anniversary date of the prior year’s annual meeting (subject to certain exceptions). Any notice by a stockholder must be accompanied by certain information as provided in the Bylaws.

The Maryland General Corporation Law provides that a Maryland corporation that has a class of securities registered under the Exchange Act and has at least three outside directors can elect to be subject to certain corporate governance provisions that may be inconsistent with the corporation’s charter or bylaws. Under the applicable statute, a board of directors may classify itself without the vote of stockholders. Further, the board of directors may, by electing into applicable statutory provisions and notwithstanding the charter or bylaws, (i) reserve for itself the right to fix the number of directors; (ii) retain for itself sole authority to fill vacancies created by an increase in the size of the board of directors or the death, removal or resignation of a director; and (iii) provide that all vacancies on the board of directors may be filled only by the affirmative vote of a majority of the remaining directors, in office, even if the remaining directors do not constitute a quorum. Any director elected to fill such vacancy shall hold office for the remainder of the unexpired term and until his or her successor is elected and qualified. A board of directors may implement all or any of these provisions without amending the charter or bylaws and without stockholder approval. A corporation may be prohibited by its charter or by resolution of its board of directors from electing any of the provisions of the statute. The Fund is not prohibited from implementing any or all of the statute.

Pursuant to the Fund’s Bylaws, the Fund has elected to be subject to a specific provision of the statute such that, at all times that the Fund is eligible to make that election, all vacancies on the Board of Directors resulting from an increase in the size of the Board or the death, resignation or removal of a Director, may be filled only by the affirmative vote of a majority of the remaining Directors, even if the remaining Directors do not constitute a quorum.]

The Fund is a diversified, closed-end management investment company (commonly referred to as a closed-end fund). Closed-end funds differ from open-end funds (which are generally referred to as mutual funds) in that closed-end funds generally list their shares for trading on a stock exchange and do not redeem their shares at the request of the shareholder. This means that if you wish to sell your shares of a closed-end fund you must trade them on the stock exchange like any other stock at the prevailing market price at that time. In a mutual fund, if the shareholder wishes to sell shares of the fund, the mutual fund will redeem or buy back the shares at NAV. Also, mutual funds generally offer new shares on a continuous basis to new investors and closed-end funds generally do not. The continuous inflows and outflows of assets in a mutual fund can make it difficult to manage the fund’s investments. By comparison, closed-end funds are generally able to stay more fully invested in securities that are consistent with their investment objectives and also have greater flexibility to make certain types of investments and to use certain investment strategies, such as financial leverage and investments in illiquid securities.

Shares of closed-end funds frequently trade at a discount to their NAV. Because of this possibility and the recognition that any such discount may not be in the interest of shareholders, the Board might consider from time to time engaging in open-market repurchases, tender offers for shares or other programs intended to reduce the discount. We cannot guarantee or assure, however, that the Board will decide to engage in any of these actions. Nor is there any guarantee or assurance that such actions, if undertaken, would result in the shares trading at a price equal or close to the NAV. See “Repurchase of Common Shares” below and “Repurchase of Common Shares” in the SAI. The Board might also consider converting the Fund to an open-end mutual fund, which would also require a vote of the shareholders of the Fund.

Shares of closed-end investment companies often trade at a discount to their NAVs and the Fund’s common shares may also trade at a discount to their NAV, although it is possible that they may trade at a premium above NAV. The market price of the Fund’s common shares will be determined by such factors as relative demand for and supply of such common shares in the market, the Fund’s NAV, general market and economic conditions and other factors beyond the control of the Fund. See “Net Asset Value” and “Description of Capital Stock—Common Shares.” Although the Fund’s common shareholders will not have the right to redeem their common shares, the Fund may take action to repurchase common shares in the open market or make tender offers for its common shares. This may have the effect of reducing any market discount from NAV.

There is no assurance that, if action is undertaken to repurchase or tender for common shares, such action will result in the common shares’ trading at a price which approximates their NAV. Although share repurchases and tender offers could have a favorable effect on the market price of the Fund’s common shares, you should be aware that the acquisition of common shares by the Fund will decrease the capital of the Fund and, therefore, may have the effect of increasing the Fund’s expense ratio and decreasing the asset coverage with respect to any borrowings or preferred shares outstanding. Any share repurchases or tender offers will be made in accordance with the requirements of the Exchange Act, the Investment Company Act and the principal stock exchange on which the common shares are traded. For additional information, see “Repurchase of Common Shares” in the SAI.

We may sell common shares, including to existing shareholders in a rights offering, through underwriters or dealers, directly to one or more purchasers (including existing shareholders in a rights offering), through agents, to or through underwriters or dealers, or through a combination of any such methods of sale. The applicable Prospectus Supplement will identify any underwriter or agent involved in the offer and sale of our common shares, any sales loads, discounts, commissions, fees or other compensation paid to any underwriter, dealer or agent, the offering price, net proceeds and use of proceeds and the terms of any sale. In the case of a rights offering, the applicable Prospectus Supplement will set forth the number of our common shares issuable upon the exercise of each right and the other terms of such rights offering.

The distribution of our common shares may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, at prevailing market prices at the time of sale, at prices related to such prevailing market prices, or at negotiated prices. Sales of our common shares may be made in transactions that are deemed to be “at the market” as defined in Rule 415 under the Securities Act, including sales made directly on the NYSE or sales made to or through a market maker other than on an exchange.

We may sell our common shares directly to, and solicit offers from, institutional investors or others who may be deemed to be underwriters as defined in the Securities Act for any resales of the securities. In this case, no underwriters or agents would be involved. We may use electronic media, including the Internet, to sell offered securities directly.

In connection with the sale of our common shares, underwriters or agents may receive compensation from us in the form of discounts, concessions or commissions. Underwriters may sell our common shares to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents that participate in the distribution of our common shares may be deemed to be underwriters under the Securities Act, and any discounts and commissions they receive from us and any profit realized by them on the resale of our common shares may be deemed to be underwriting discounts and commissions under the Securities Act. Any such underwriter or agent will be identified and any such compensation received from us will be described in the applicable Prospectus Supplement. The maximum amount of compensation to be

received by any Financial Industry Regulatory Authority member or independent broker-dealer will not exceed eight percent for the sale of any securities being offered pursuant to Rule 415 under the Securities Act. We will not pay any compensation to any underwriter or agent in the form of warrants, options, consulting or structuring fees or similar arrangements. In connection with any rights offering to existing shareholders, we may enter into a standby underwriting arrangement with one or more underwriters pursuant to which the underwriter(s) will purchase common shares remaining unsubscribed after the rights offering.

If a Prospectus Supplement so indicates, we may grant the underwriters an option to purchase additional common shares at the public offering price, less the underwriting discounts and commissions, within 45 days from the date of the Prospectus Supplement, to cover any over-allotments.

Under agreements into which we may enter, underwriters, dealers and agents who participate in the distribution of our common shares may be entitled to indemnification by us against certain liabilities, including liabilities under the Securities Act. Underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business.

If so indicated in the applicable Prospectus Supplement, we will ourselves, or will authorize underwriters or other persons acting as our agents to solicit offers by certain institutions to purchase our common shares from us pursuant to contracts providing for payment and delivery on a future date. Institutions with which such contacts may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others, but in all cases such institutions must be approved by us. The obligation of any purchaser under any such contract will be subject to the condition that the purchase of the common shares shall not at the time of delivery be prohibited under the laws of the jurisdiction to which such purchaser is subject. The underwriters and such other agents will not have any responsibility in respect of the validity or performance of such contracts. Such contracts will be subject only to those conditions set forth in the Prospectus Supplement, and the Prospectus Supplement will set forth the commission payable for solicitation of such contracts.

To the extent permitted under the Investment Company Act and the rules and regulations promulgated thereunder, the underwriters may from time to time act as brokers or dealers and receive fees in connection with the execution of our portfolio transactions after the underwriters have ceased to be underwriters and, subject to certain restrictions, each may act as a broker while it is an underwriter.

A Prospectus and accompanying Prospectus Supplement in electronic form may be made available on the websites maintained by underwriters. The underwriters may agree to allocate a number of securities for sale to their online brokerage account holders. Such allocations of securities for Internet distributions will be made on the same basis as other allocations. In addition, securities may be sold by the underwriters to securities dealers who resell securities to online brokerage account holders.

In order to comply with the securities laws of certain states, if applicable, our common shares offered hereby will be sold in such jurisdictions only through registered or licensed brokers or dealers.

The Fund is committed to maintaining the privacy of shareholders and to safeguarding their non-public personal information. The following information is provided to help you understand what personal information the Fund collects, how we protect that information, and why in certain cases we may share such information with select other parties.

The Fund does not receive any non-public personal information relating to its shareholders who purchase shares through their broker-dealers. In the case of shareholders who are record holders of the Fund, the Fund

receives personal non-public information on account applications or other forms. With respect to these shareholders, the Fund also has access to specific information regarding their transactions in the Fund.

The Fund does not disclose any non-public personal information about its shareholders or former shareholders to anyone, except as permitted by law or as is necessary in order to service our shareholders’ accounts (for example, to a transfer agent).

The Fund restricts access to non-public personal information about its shareholders to BlackRock employees with a legitimate business need for the information. The Fund maintains physical, electronic and procedural safeguards designed to protect the non-public personal information of our shareholders.

BlackRock Advisors, LLC (previously defined as the “Advisor”) is the Fund’s investment adviser. The Advisor receives an annual fee, payable monthly, in an amount equal to 0.55% of the average daily value of the Fund’s Net Assets. “Net Assets” means the total assets of the Fund minus the sum of its accrued liabilities.

The Offering

[The provisions of the Investment Company Act generally require that the public offering price of common shares (less any underwriting commissions and discounts) must equal or exceed the net asset value per share of a company’s common shares (calculated within 48 hours of pricing).

Sales of our common shares, if any, under this Prospectus Supplement and the accompanying Prospectus may be made in negotiated transactions or transactions that are deemed to be “at the market” as defined in Rule 415 under the Securities Act, including sales made directly on the NYSE or sales made to or through a market maker other than on an exchange.]

Use of Proceeds

We currently anticipate that we will be able to invest all of the net proceeds of any sales of common shares pursuant to this Prospectus Supplement in accordance with our investment objective and policies as described in the accompanying Prospectus under “The Fund’s Investments” within approximately three months of the receipt of such proceeds. Pending such investment, it is anticipated that the proceeds will be invested in short-term investment grade securities or in high quality, short-term money market instruments. Depending on market conditions and operations, a portion of the cash held by the Fund, including any proceeds raised from the offering, may be used to pay distributions in accordance with the Fund’s distribution policy and may be a return of capital.

The following example illustrates the expenses (including the sales load of $[●] and offering costs of $[●]) that you would pay on a $1,000 investment in common shares, assuming (i) total net annual expenses of [●]% of net assets attributable to common shares and (ii) a 5% annual return:

The example should not be considered a representation of future expenses. The example assumes that the estimated “Other expenses” set forth in the Estimated Annual Expenses table are accurate and that all dividends and distributions are reinvested at net asset value. Actual expenses may be greater or less than those assumed. Moreover, the Fund’s actual rate of return may be greater or less than the hypothetical 5% return shown in the example.

We estimate the total net proceeds of the offering to be $[●], based on the public offering price of $[●] per share and after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

The net proceeds from the issuance of common shares hereunder will be invested in accordance with the Fund’s investment objective and policies as set forth in this Prospectus Supplement and the accompanying Prospectus. We currently anticipate that we will be able to invest all of the net proceeds in accordance with our investment objective and policies within approximately three months of the receipt of such proceeds. Pending such investment, it is anticipated that the proceeds will be invested in short-term investment grade securities or in high quality, short-term money market instruments. Depending on market conditions and operations, a portion of the cash held by the Fund, including any proceeds raised from the offering, may be used to pay distributions in accordance with the Fund’s distribution policy and may be a return of capital. A return of capital is a return to investors of a portion of their original investment in the Fund. In general terms, a return of capital would involve a situation in which a Fund distribution (or a portion thereof) represents a return of a portion of a shareholder’s investment in the Fund, rather than making a distribution that is funded from the Fund’s earned income or other profits. Although return of capital distributions may not be currently taxable, such distributions would decrease the basis of a shareholder’s shares, and therefore, may increase a shareholder’s tax liability for capital gains upon a sale of shares, even if sold at a loss to the shareholder’s original investments.

The following table sets forth the unaudited capitalization of the Fund as of [●], 2020 and its adjusted capitalization assuming the common shares available in the offering discussed in this Prospectus Supplement had been issued.

Certain legal matters in connection with the common shares will be passed upon for the Fund by Willkie Farr & Gallagher LLP, New York, New York, counsel to the Fund. Willkie Farr & Gallagher LLP may rely as to certain matters of Maryland law on the opinion of Miles & Stockbridge, P.C., Baltimore, Maryland. [Certain legal matters will be passed on by [●] as special counsel to the Underwriters in connection with the offering.]

SUMMARY OF THE TERMS OF THE RIGHTS OFFERING

Terms of the Rights Offering

[●] transferable subscription right (a “Right”) will be issued for each share of common stock of BlackRock MuniAssets Fund, Inc. (the “Fund,” “we,” “us” or “our”) (each, a “Common Share,” and collectively, the “Common Shares”) held on the Record Date (as defined below). Rights are expected to trade on the [●] under the symbol “[●].” The Rights will allow common shareholders to subscribe for new Common Shares of the Fund. [●] Common Shares of the Fund are outstanding as of [●], 2020. [●] Rights will be required to purchase one Common Share. Shares of the Fund, as a closed-end fund, can trade at a discount to net asset value (“NAV”). Upon exercise of the Rights offering, Fund shares are expected to be issued at a price below NAV per Common Share. [An over-subscription privilege will be offered, [subject to the right of the Board of Directors of the Fund (the “Board”) to eliminate the over-subscription privilege.] [●] Common Shares of the Fund will be issued if all Rights are exercised. See “Terms of the Rights Offering.” Any Common Shares issued as a result of the Rights offering will not be record date shares for the Fund’s monthly distribution to be paid on [●], 2020 and will not be entitled to receive such distribution. The exercise of rights by a shareholder is irrevocable.

Amount Available for Primary Subscription

Approximately $[●], before expenses.

Title

Subscription Rights to Acquire Shares of Common Stock

Subscription Price

The final subscription price per Common Share (the “Subscription Price”) will be determined based upon a formula equal to [●]% of the average of the last reported sales price of the Fund’s Common Shares on the New York Stock Exchange (“NYSE”) on the Expiration Date (as defined below) and each of the [four] preceding trading days (the “Formula Price”). If, however, the Formula Price is less than [●]% of the NAV per Common Share of the Fund’s Common Shares at the close of trading on the NYSE on the Expiration Date, then the Subscription Price will be [●]% of the Fund’s NAV per Common Share at the close of trading on the NYSE on that day. See “Terms of the Rights Offering.”

Record Date

Rights will be issued to holders of record of the Fund’s Common Shares as of the close of business on [●], 2020 (the “Record Date”). See “Terms of the Rights Offering.”

Number of Rights Issued

[●] Right will be issued in respect of each Common Share of the Fund outstanding as of the close of business on the Record Date. See “Terms of the Rights Offering.”

Number of Rights Required to Purchase One Common Share

A holder of Rights may purchase [●] Common Share of the Fund for every [●] Rights exercised. The number of Rights to be issued to a shareholder as of the close of business on the Record Date will be rounded up to the nearest number of Rights evenly divisible by [●]. See “Terms of the Rights Offering.”

Over-Subscription Privilege

Holders of Common Shares as of the close of business on the Record Date (“Record Date Shareholders”) who fully exercise all Rights initially issued to them are entitled to buy those Common Shares, referred to as “primary over-subscription shares,” that were not purchased by other Rights holders at the same Subscription Price. If enough primary over-subscription shares are available, all such requests will be honored in full. If the requests for primary over-subscription shares exceed the primary over-subscription shares available, the available primary over-subscription shares will be allocated pro rata among those fully exercising Record Date Shareholders who over-subscribe based on the number of Rights originally issued to them by the Fund. Common Shares acquired pursuant to the primary over-subscription privilege are subject to allotment. Rights acquired in the secondary market may not participate in the primary over-subscription privilege.

[In addition, the Fund, in its sole discretion, may determine to issue additional Common Shares at the same Subscription Price in an amount of up to [●]% of the shares issued pursuant to the primary subscription, referred to as “secondary over-subscription shares.” Should the Fund determine to issue some or all of the secondary over-subscription shares, they will be allocated only among Record Date Shareholders who submitted over-subscription requests. Secondary over-subscription shares will be allocated pro rata among those fully exercising Record Date Shareholders who over-subscribe based on the number of Rights originally issued to them by the Fund. Rights acquired in the secondary market may not participate in the secondary over-subscription privilege.]

Notwithstanding the above, the Board has the right in its absolute discretion to eliminate the primary over-subscription privilege and/or secondary over-subscription privilege (together, the “over-subscription privilege”) if it considers it to be in the best interest of the Fund to do so. The Board may make that determination at any time, without prior notice to Rights holders or others, up to and including the fifth day following the Expiration Date (as defined below). See “Over-Subscription Privilege.”

Any Common Shares issued pursuant to the over-subscription privilege will be shares registered under the Prospectus.

Transfer of Rights

The Rights will be transferable. See “Terms of the Rights Offering,” “Sales by Rights Agent” and “Method of Transferring Rights.”

Subscription Period

The Rights may be exercised at any time after issuance and prior to expiration of the Rights (the “Subscription Period”), which will be [5:00 PM Eastern Time] on [●], 2020 (the “Expiration Date”), unless otherwise extended. See “Terms of the Rights Offering” and “Method of Exercise of Rights.” The Rights offering may be terminated [or extended] by the Fund at any time for any reason before the Expiration Date. If the Fund terminates the rights offering, the Fund will issue a press release announcing such termination and will direct the Rights Agent (defined below) to return, without interest, all subscription proceeds received to such shareholders who had elected to purchase Common Shares.

Offering Expenses

The expenses of the Rights offering are expected to be approximately $[●] and will be borne by holders of the Fund’s Common Shares. See “Use of Proceeds.”

Sale of Rights

The Rights are transferable until the completion of the Subscription Period and will be admitted for trading on the [●] under the symbol “[●]”. Although no assurance can be given that a market for the Rights will develop, trading in the Rights on the [●] is expected to begin two Business Days prior to the Record Date and may be conducted until the close of trading on the last [●] trading day prior to the Expiration Date. For purposes of this Prospectus Supplement, a “Business Day” shall mean any day on which trading is conducted on the [●].

The value of the Rights, if any, will be reflected by their market price on the [●]. Rights may be sold by individual holders through their broker or financial advisor or may be submitted to the Rights Agent (defined below) for sale. Any Rights submitted to the Rights Agent for sale must be received by the Rights Agent prior to [5:00 PM, Eastern Time], on or before [●], 2020, [●] Business Days prior to the Expiration Date (or, if the Subscription Period is extended, prior to [5:00 PM, Eastern Time], on the [●] Business Day prior to the extended Expiration Date).

Rights that are sold will not confer any right to acquire any Common Shares in any over-subscription, and any Record Date Shareholder who sells any Rights will not be eligible to participate in the over-subscription privilege, if any.

Trading of the Rights on the [●] will be conducted on a when-issued basis until and including the date on which the Subscription Certificates (as defined below) are mailed to Record Date Shareholders of record and thereafter will be conducted on a regular-way basis until and including the last [●] trading day prior to the completion of the Subscription Period. The shares are expected to begin trading ex-Rights one Business Day prior to the Record Date.

If the Rights Agent receives Rights for sale in a timely manner, the Rights Agent will use its best efforts to sell the Rights on the [●]. The Rights Agent will also attempt to sell any Rights attributable to shareholders of record whose addresses are outside the United States, or who have an APO or FPO address. See “Foreign Restrictions.” The Rights Agent will attempt to sell such Rights, including by first offering such Rights to the Dealer Manager (defined below) for purchase by the Dealer Manager at the then-current market price on the [●]. The Rights Agent will offer Rights to the Dealer Manager before attempting to sell them on the [●].

Any commissions will be paid by the selling Rights holders. Neither the Fund nor the Rights Agent will be responsible if Rights cannot be sold and neither has guaranteed any minimum sales price for the Rights. If the Rights can be sold, sales of these Rights will be deemed to have been effected at the weighted average price received by the Rights Agent on the day such Rights are sold, less any applicable brokerage commissions, taxes and other expenses (i.e., costs incidental to the sale of Rights).

For a discussion of actions that may be taken by [●] (the “Dealer Manager”) to seek to facilitate the trading market for Rights and the placement of Common Shares pursuant to the exercise of Rights, including the purchase of Rights and the sale during the Subscription Period by the Dealer Manager of Common Shares acquired through the exercise of Rights and the terms on which such sales will be made, see “Plan of Distribution.”

Shareholders are urged to obtain a recent trading price for the Rights on the [●] from their broker, bank, financial advisor or the financial press.

Banks, broker-dealers and trust companies that hold shares for the accounts of others are advised to notify those persons that purchase Rights in the secondary market that such Rights will not participate in any over-subscription privilege. See “Terms of the Rights Offering” and “Sales by Rights Agent.”

Use of Proceeds

The Fund estimates the net proceeds of the Rights offering to be approximately $[●]. This figure is based on the Subscription Price per Common Share of $[●] ([●]% of the last reported sales price of the Fund’s Common Shares on the NYSE on [●], 2020) and assumes all new Common Shares offered are sold and that the expenses related to the Rights offering estimated at approximately $[●] are paid.

The Advisor anticipates that investment of the proceeds will be made in accordance with the Fund’s investment objective and policies as appropriate investment opportunities are identified, which is expected to be substantially completed in approximately [three] months; however, the identification of appropriate investment opportunities

pursuant to the Fund’s investment style or changes in market conditions may cause the investment period to extend as long as [six] months. Pending such investment, the proceeds will be held in [cash and/or high quality, short-term debt securities and instruments].

Depending on market conditions and operations, a portion of the cash held by the Fund, including any proceeds raised from the offering, may be used to pay distributions in accordance with the Fund’s distribution policy and may be a return of capital. A return of capital is a return to investors of a portion of their original investment in the Fund. In general terms, a return of capital would involve a situation in which a Fund distribution (or a portion thereof) represents a return of a portion of a shareholder’s investment in the Fund, rather than making a distribution that is funded from the Fund’s earned income or other profits. Although return of capital distributions may not be currently taxable, such distributions would decrease the basis of a shareholder’s shares, and therefore, may increase a shareholder’s tax liability for capital gains upon a sale of shares, even if sold at a loss to the shareholder’s original investments. See “Use of Proceeds.”

Taxation/ERISA

See “Taxation” and “Employee Benefit Plan and IRA Considerations.”

Rights Agent

[●]. See “Rights Agent.”

Information Agent

[●]. See “Information Agent.”

The Fund is issuing to Record Date Shareholders Rights to subscribe for Common Shares of the Fund. Each Record Date Shareholder is being issued one transferable Right for each Common Share owned on the Record Date. The Rights entitle the holder to acquire, at a subscription price per Common Share (the “Subscription Price”) determined based upon a formula equal to [●]% of the average of the last reported sales price of the Fund’s Common Shares on the NYSE on the Expiration Date (as defined below) and each of the [four] preceding trading days (the “Formula Price”), [●] new Common Share for each [●] Rights held. If, however, the Formula Price is less than [●]% of the NAV per Common Share of the Fund’s Common Shares at the close of trading on the NYSE on the Expiration Date, then the Subscription Price will be [●]% of the Fund’s NAV per Common Share at the close of trading on the NYSE on that day. The estimated Subscription Price to the public of $[●] is based upon [●]% of the last reported sales price of the Fund’s Common Shares on the NYSE on [●], 2020. Fractional shares will not be issued upon the exercise of the Rights. Accordingly, Common Shares may be purchased only pursuant to the exercise of Rights in integral multiples of [●]. The number of Rights to be issued to a Record Date Shareholder will be rounded up to the nearest number of Rights evenly divisible by [●]. In the case of Common Shares held of record by Cede & Co. (“Cede”), as nominee for the Depository Fund Company (“DTC”)], or any other depository or nominee, the number of Rights issued to Cede or such other depository or nominee will be adjusted to permit rounding up (to the nearest number of Rights evenly divisible by [●]) of the Rights to be received by beneficial owners for whom it is the holder of record only if [insert nominee name] or such other depository or nominee provides to the Fund on or before the close of business on [●], 2020 written representation of the number of Rights required for such rounding. Rights may be exercised at any time during the period (the “Subscription Period”) which commences on [●], 2020, and ends at [5:00 PM Eastern Time] on [●], 2020 (the “Expiration Date”), unless otherwise extended. Shares of the Fund, as a closed-end fund, can trade at a discount to NAV. Upon exercise of the Rights offering, Fund shares are expected to be issued at a price below NAV per Common Share. The right to acquire one Common Share for each [●] Rights held during the Subscription Period (or any extension of the Subscription Period) at the Subscription Price will be referred to in the remainder of this Prospectus Supplement as the “Rights offering.” Rights will expire on the Expiration Date and thereafter may not be exercised. Any Common Shares issued as a result of the Rights offering will not be Record Date shares for the Fund’s monthly distribution to be paid on [●], 2019 and will not be entitled to receive such distribution.

The Fund has entered into a dealer manager agreement with [●] (the “Dealer Manager”) that allows the Dealer Manager to take actions to seek to facilitate the trading market for Rights and the placement of Common Shares pursuant to the exercise of Rights. Those actions are expected to involve the Dealer Manager purchasing and exercising Rights during the Subscription Period at prices determined at the time of such exercise, which are expected to vary from the Subscription Price. See “Plan of Distribution” for additional information.

Rights may be evidenced by subscription certificates or may be uncertificated and evidenced by other appropriate documentation (i.e., a rights card distributed to registered shareholders in lieu of a subscription certificate) (“Subscription Certificates”). The number of Rights issued to each holder will be stated on the Subscription Certificate delivered to the holder. The method by which Rights may be exercised and Common Shares paid for is set forth below in “Method of Exercise of Rights,” “Payment for Shares” and “Plan of Distribution.” A holder of Rights will have no right to rescind a purchase after [●] (the “Rights Agent”) has received payment. See “Payment for Shares” below. It is anticipated that the Common Shares issued pursuant to an exercise of Rights will be listed on the [●].

[Holders of Rights [who are Record Date Shareholders] are entitled to subscribe for additional Common Shares at the same Subscription Price pursuant to the over-subscription privilege, subject to certain limitations, allotment and the right of the Board to eliminate the primary over-subscription privilege [or secondary] over-subscription privilege. See “Over-Subscription Privilege” below.]

For purposes of determining the maximum number of Common Shares that may be acquired pursuant to the Rights offering, broker-dealers, trust companies, banks or others whose shares are held of record by Cede or by any other depository or nominee will be deemed to be the holders of the Rights that are held by Cede or such other depository or nominee on their behalf.

The Rights are transferable until the completion of the Subscription Period and will be admitted for trading on the [●] under the symbol “[●].” Assuming a market exists for the Rights, the Rights may be purchased and sold through usual brokerage channels and also sold through the Rights Agent. Although no assurance can be given that a market for the Rights will develop, trading in the Rights on the [●] is expected to begin two Business Days prior to the Record Date and may be conducted until the close of trading on the last [●] trading day prior to the Expiration Date. Trading of the Rights on the [●] is expected to be conducted on a when-issued basis until and including the date on which the Subscription Certificates are mailed to Record Date Shareholders of record and thereafter is expected to be conducted on a regular way basis until and including the last [●] trading day prior to the Expiration Date. The method by which Rights may be transferred is set forth below under “Method of Transferring Rights.” The Common Shares are expected to begin trading ex-Rights one Business Day prior to the Record Date as determined and announced by the [●]. The Rights offering may be terminated or extended by the Fund at any time for any reason before the Expiration Date. If the Fund terminates the Rights offering, the Fund will issue a press release announcing such termination and will direct the Rights Agent to return, without interest, all subscription proceeds received to such shareholders who had elected to purchase Common Shares.

Nominees who hold the Fund’s Common Shares for the account of others, such as banks, broker-dealers, trustees or depositories for securities, should notify the respective beneficial owners of such shares as soon as possible to ascertain such beneficial owners’ intentions and to obtain instructions with respect to the Rights. If the beneficial owner so instructs, the nominee should complete the Subscription Certificate and submit it to the Rights Agent with proper payment. In addition, beneficial owners of the Common Shares or Rights held through such a nominee should contact the nominee and request the nominee to effect transactions in accordance with such beneficial owner’s instructions.

[Participants in the Fund’s Dividend Reinvestment Plan (the “Plan”) will be issued Rights in respect of the Common Shares held in their accounts in the Plan. Participants wishing to exercise these Rights must exercise the Rights in accordance with the procedures set forth in “Method of Exercise of Rights” and “Payment for Shares.”]

The Rights offering is being made in accordance with the Investment Company Act of 1940 Act, as amended (the “Investment Company Act”) without 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 Board has the right in its absolute discretion to eliminate the over-subscription privilege with respect to primary over-subscription shares and secondary over-subscription shares if it considers it to be in the best interest of the Fund to do so. The Board may make that determination at any time, without prior notice to Rights holders or others, up to and including the fifth day following the Expiration Date. If the primary over-subscription privilege is not eliminated, it will operate as set forth below.

Rights holders [who are Record Date Shareholders and who fully exercise their Rights] are entitled to subscribe for additional Common Shares at the same Subscription Price pursuant to the over-subscription privilege, subject to certain limitations and subject to allotment.

[Record Date Shareholders who fully exercise all Rights initially issued to them] are entitled to buy those Common Shares, referred to as “primary over-subscription shares,” that were not purchased by other holders of Rights at the same Subscription Price. If enough primary over-subscription shares are available, all such requests will be honored in full. If the requests for primary over-subscription shares exceed the primary over-subscription shares available, the available primary over-subscription shares will be allocated pro rata among those fully exercising [Record Date Shareholders] who over-subscribe based on the number of Rights originally issued to them by the Fund. Common Shares acquired pursuant to the over-subscription privilege are subject to allotment.

[In addition, the Fund, in its sole discretion, may determine to issue additional Common Shares at the same Subscription Price in an amount of up to [ ]% of the shares issued pursuant to the primary subscription, referred to as “secondary over-subscription shares.” Should the Fund determine to issue some or all of the secondary over-subscription shares, they will be allocated only among Record Date Shareholders who submitted over-subscription requests. Secondary over-subscription shares will be allocated pro rata among those fully exercising Record Date Shareholders who over-subscribe based on the number of Rights originally issued to them by the Fund. Rights acquired in the secondary market may not participate in the over-subscription privilege.]

Record Date Shareholders who are fully exercising their Rights during the Subscription Period should indicate, on the Subscription Certificate that they submit with respect to the exercise of the Rights issued to them, how many Common Shares they are willing to acquire pursuant to the over-subscription privilege. Rights acquired in the secondary market may not participate in the over-subscription privilege.

To the extent sufficient Common Shares are not available to fulfill all over-subscription requests, unsubscribed Common Shares (the “Excess Shares”) will be allocated pro rata among those Record Date Shareholders who over-subscribe based on the number of Rights issued to them by the Fund. The allocation process may involve a series of allocations in order to assure that the total number of Common Shares available for over-subscriptions is distributed on a pro rata basis.

Banks, broker-dealers, trustees and other nominee holders of Rights will be required to certify to the Rights Agent, before any over-subscription privilege may be exercised with respect to any particular beneficial owner, as to the aggregate number of Rights exercised during the Subscription Period and the number of Common Shares subscribed for pursuant to the over-subscription privilege by such beneficial owner and that such beneficial owner’s subscription was exercised in full. Nominee holder over-subscription forms and beneficial owner certification forms will be distributed to banks, broker-dealers, trustees and other nominee holders of Rights with the Subscription Certificates. [Nominees should also notify holders purchasing Rights in the secondary market that such Rights may not participate in the over-subscription privilege.]

The Fund will not otherwise offer or sell any Common Shares that are not subscribed for pursuant to the primary subscription, the primary over-subscription privilege or the secondary over-subscription privilege pursuant to the Rights offering.]

Holders of Rights who are unable or do not wish to exercise any or all of their Rights may instruct the Rights Agent to sell any unexercised Rights. The Subscription Certificates representing the Rights to be sold by the Rights Agent must be received prior to [5:00 PM, Eastern Time], on [●], 2020, five Business Days prior to the Expiration Date (or, if the Subscription Period is extended, prior to [5:00 PM, Eastern Time], on the fifth Business Day prior to the extended Expiration Date). Upon the timely receipt of the appropriate instructions to sell Rights, the Rights Agent will use its best efforts to complete the sale and will remit the proceeds of sale, net of any commissions, to the holders. The Rights Agent will also attempt to sell any Rights attributable to shareholders of record whose addresses are outside the United States, or who have an APO or FPO address. The selling Rights holder will pay all brokerage commissions incurred by the Rights Agent. These sales may be effected by the Rights Agent. The Rights Agent will automatically attempt to sell any unexercised Rights that remain unclaimed as a result of Subscription Certificates being returned by the postal authorities as undeliverable as of the [●] Business Day prior to the Expiration Date. The Rights Agent will attempt to sell such Rights, including by first offering such Rights to the Dealer Manager for purchase by the Dealer Manager at the then-current market price on the [●]. The Rights Agent will offer Rights to the Dealer Manager before attempting to sell them on the [●], which may affect the market price for Rights on the [●] and reduce the number of Rights available for purchase on the [●], thereby reducing the ability of new investors to participate in the offering. These sales will be made net of commissions, taxes and any other expenses paid on behalf of the nonclaiming holders of Rights. Proceeds from those sales will be held by Computershare Fund Company, N.A. in its capacity as the Fund’s transfer agent, for the account of the nonclaiming holder of Rights until the proceeds are either claimed or escheated. There can be no assurance that the Rights Agent will be able to complete the sale of any of these Rights and neither the Fund nor the Rights Agent has guaranteed any minimum sales price for the Rights. All of these Rights will be sold at the market price, if any, through an exchange or market trading the Rights. If the Rights can be sold, sales of the Rights will be deemed to have been effected at the weighted average price received by the Rights Agent on the day such Rights are sold, less any applicable brokerage commissions, taxes and other expenses.

[●] (previously defined as the “Dealer Manager”), a registered broker-dealer, may also act on behalf of its clients to purchase or sell Rights in the open market and may receive commissions from its clients for such services. Holders of Rights attempting to sell any unexercised Rights in the open market through a broker-dealer other than the Dealer Manager may be charged a different commission and should consider the commissions and fees charged by the broker-dealer prior to selling their Rights on the open market. The Dealer Manager is not expected to purchase Rights as principal for its own account in order to seek to facilitate the trading market for Rights or otherwise. See “Plan of Distribution” for additional information.]

The Rights are transferable and will be admitted for trading on the [●] under the symbol “[●].” Although no assurance can be given that a market for the Rights will develop, trading in the Rights on the [●] is expected to begin two Business Days prior to the Record Date and may be conducted until the close of trading on the last [●] trading day prior to the Expiration Date.

The value of the Rights, if any, will be reflected by the market price. Rights may be sold by individual holders or may be submitted to the Rights Agent for sale. Any Rights submitted to the Rights Agent for sale must be received by the Rights Agent prior to [5:00 PM, Eastern Time], on [●], 2020, five Business Days prior to the Expiration Date (or, if the Subscription Period is extended, prior to [5:00 PM, Eastern Time], on the [●] Business Day prior to the extended Expiration Date).

[Rights that are sold will not confer any right to acquire any Common Shares in any primary over-subscription privilege or secondary over-subscription privilege, if any, and any Record Date Shareholder who sells any Rights will not be eligible to participate in the primary over-subscription privilege or secondary over-subscription privilege, if any.]

Trading of the Rights on the [●] will be conducted on a when-issued basis until and including the date on which the Subscription Certificates are mailed to Record Date Shareholders of record and thereafter will be conducted on a regular-way basis until and including the last [●] trading day prior to the Expiration Date. The Common Shares are expected to begin trading ex-Rights one Business Day prior to the Record Date.

Shareholders are urged to obtain a recent trading price for the Rights on the [●] from their broker, bank, financial advisor or the financial press.

The Rights evidenced by a single Subscription Certificate may be transferred in whole by endorsing the Subscription Certificate for transfer in accordance with the accompanying instructions. A portion of the Rights evidenced by a single Subscription Certificate (but not fractional Rights) may be transferred by delivering to the Rights Agent a Subscription Certificate properly endorsed for transfer, with instructions to register the portion of the Rights evidenced thereby in the name of the transferee (and to issue a new Subscription Certificate to the transferee evidencing the transferred Rights). In this event, a new Subscription Certificate evidencing the balance of the Rights will be issued to the Rights holder or, if the Rights holder so instructs, to an additional transferee.

Holders wishing to transfer all or a portion of their Rights (but not fractional Rights) should promptly transfer such Rights to ensure that: (i) the transfer instructions will be received and processed by the Rights Agent, (ii) a new Subscription Certificate will be issued and transmitted to the transferee or transferees with respect to transferred Rights, and to the holder with respect to retained Rights, if any, and (iii) the Rights evidenced by the new Subscription Certificates may be exercised or sold by the recipients thereof prior to the Expiration Date. Neither the Fund nor the Rights Agent shall have any liability to a transferee or holder of Rights if Subscription Certificates are not received in time for exercise or sale prior to the Expiration Date.

Except for the fees charged by the Rights Agent (which will be paid by the Fund as described below), all commissions, fees and other expenses (including brokerage commissions and transfer taxes) incurred in connection with the purchase, sale, transfer or exercise of Rights will be for the account of the holder of the Rights, and none of these commissions, fees or expenses will be borne by the Fund or the Rights Agent.

The Fund anticipates that the Rights will be eligible for transfer through, and that the exercise of the Rights may be effected through, the facilities of [insert depository] (Rights exercised through [insert depository] are referred to as “[insert depository] Exercised Rights”).

The Rights Agent is [●]. The Rights Agent will receive from the Fund an amount estimated to be $[●], comprised of the fee for its services and the reimbursement for certain expenses related to the Rights offering. The shareholders of the Fund will indirectly pay such amount.

INQUIRIES BY ALL HOLDERS OF RIGHTS SHOULD BE DIRECTED TO: THE INFORMATION AGENT, [●]; HOLDERS PLEASE CALL TOLL-FREE AT [●]; BANKS AND BROKERS PLEASE CALL [●].

Rights may be exercised by completing and signing the Subscription Certificate and mailing it in the envelope provided, or otherwise delivering the completed and signed Subscription Certificate to the Rights Agent, together with payment for the Common Shares as described below under “Payment for Shares.” Rights may also be exercised through the broker of a holder of Rights, who may charge the holder of Rights a servicing fee in connection with such exercise. See “Plan of Distribution” for additional information regarding the purchase and exercise of Rights by the Dealer Manager.

Completed Subscription Certificates and payment must be received by the Rights Agent prior to [5:00 PM Eastern Time], on the Expiration Date (unless payment is effected by means of a notice of guaranteed delivery as described below under “Payment for Shares”). Your broker, bank, trust company or other intermediary may impose a deadline for exercising Rights earlier than [5:00 PM, Eastern Time], on the Expiration Date. The Subscription Certificate and payment should be delivered to the Rights Agent at the following address:

Holders of Rights who acquire Common Shares in the Rights offering may choose between the following methods of payment:

A PAYMENT PURSUANT TO THIS METHOD MUST BE IN UNITED STATES DOLLARS BY CHECK (WHICH MUST INCLUDE THE NAME OF THE SHAREHOLDER ON THE CHECK) DRAWN ON A BANK LOCATED IN THE CONTINENTAL UNITED STATES, MUST BE PAYABLE TO BLACKROCK MUNIASSETS FUND, INC. AND MUST ACCOMPANY AN EXECUTED SUBSCRIPTION CERTIFICATE TO BE ACCEPTED.

The method and timing of payment for Common Shares acquired by the Dealer Manager through the exercise of Rights is described under “Plan of Distribution.”

If a holder of Rights who acquires Common Shares pursuant to the Rights offering does not make payment of all amounts due, the Fund reserves the right to take any or all of the following actions: (i) find other purchasers for such subscribed-for and unpaid-for Common Shares; (ii) apply any payment actually received by it toward the purchase of the greatest whole number of Common Shares which could be acquired by such holder upon exercise of the Rights or any over-subscription privilege; (iii) sell all or a portion of the Common Shares purchased by the holder, in the open market, and apply the proceeds to the amounts owed; and (iv) exercise any and all other rights or remedies to which it may be entitled, including, without limitation, the right to set off against payments actually received by it with respect to such subscribed Common Shares and to enforce the relevant guarantee of payment.

Any payment required from a holder of Rights must be received by the Rights Agent prior to [5:00 PM Eastern Time] on the Expiration Date. Issuance and delivery of the Common Shares purchased are subject to collection of checks.

Within [●] Business Days following the Expiration Date (the “Confirmation Date”), a confirmation will be sent by the Rights Agent to each holder of Rights (or, if the Common Shares are held by [insert nominee name] or any other depository or nominee, to [insert nominee name] or such other depository or nominee), showing (i) the number of Common Shares acquired pursuant to the subscription, (ii) the number of Common Shares, if any, acquired pursuant to the over-subscription privilege, and (iii) the per share and total purchase price for the

Common Shares. Any payment required from a holder of Rights must be received by the Rights Agent on or prior to the Expiration Date. Any excess payment to be refunded by the Fund to a holder of Rights, or to be paid to a holder of Rights as a result of sales of Rights on its behalf by the Rights Agent, will be mailed by the Rights Agent to the holder within [•] Business Days after the Expiration Date.

A holder of Rights will have no right to rescind a purchase after the Rights Agent has received payment either by means of a notice of guaranteed delivery or a check, which must include the name of the shareholder on the check.

Upon acceptance of a subscription, all funds received by the Rights Agent shall be held by the Rights Agent as agent for the Fund and deposited in one or more bank accounts. Such funds may be invested by the Rights Agent in: bank accounts, short-term certificates of deposit, bank repurchase agreements, and disbursement accounts with commercial banks meeting certain standards. The Rights Agent may receive interest, dividends or other earnings in connection with such deposits or investments.

Holders, such as broker-dealers, trustees or depositories for securities, who hold Common Shares for the account of others, should notify the respective beneficial owners of the Common Shares as soon as possible to ascertain such beneficial owners’ intentions and to obtain instructions with respect to the Rights. If the beneficial owner so instructs, the record holder of the Rights should complete Subscription Certificates and submit them to the Rights Agent with the proper payment. In addition, beneficial owners of Common Shares or Rights held through such a holder should contact the holder and request that the holder effect transactions in accordance with the beneficial owner’s instructions. [Banks, broker-dealers, trustees and other nominee holders that hold Common Shares of the Fund for the accounts of others are advised to notify those persons that purchase Rights in the secondary market that such Rights may not participate in any over-subscription privilege offered.]

THE INSTRUCTIONS ACCOMPANYING THE SUBSCRIPTION CERTIFICATES SHOULD BE READ CAREFULLY AND FOLLOWED IN DETAIL. DO NOT SEND SUBSCRIPTION CERTIFICATES TO THE FUND.

THE METHOD OF DELIVERY OF SUBSCRIPTION CERTIFICATES AND PAYMENT OF THE SUBSCRIPTION PRICE TO THE RIGHTS AGENT WILL BE AT THE ELECTION AND RISK OF THE RIGHTS HOLDERS, BUT IF SENT BY MAIL IT IS RECOMMENDED THAT THE CERTIFICATES AND PAYMENTS BE SENT BY REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, AND THAT A SUFFICIENT NUMBER OF DAYS BE ALLOWED TO ENSURE DELIVERY TO THE RIGHTS AGENT AND CLEARANCE OF PAYMENT PRIOR TO [5:00 PM EASTERN TIME], ON THE EXPIRATION DATE. BECAUSE UNCERTIFIED PERSONAL CHECKS MAY TAKE AT LEAST FIVE BUSINESS DAYS TO CLEAR, YOU ARE STRONGLY URGED TO PAY, OR ARRANGE FOR PAYMENT, BY MEANS OF A CERTIFIED OR CASHIER’S CHECK, WHICH MUST INCLUDE THE NAME OF THE SHAREHOLDER ON THE CHECK.

All questions concerning the timeliness, validity, form and eligibility of any exercise of Rights will be determined by the Fund, whose determinations will be final and binding. The Fund in its sole discretion may waive any defect or irregularity, or permit a defect or irregularity to be corrected within such time as it may determine, or reject the purported exercise of any Right. Subscriptions will not be deemed to have been received or accepted until all irregularities have been waived or cured within such time as the Fund determines in its sole discretion. Neither the Fund nor the Rights Agent will be under any duty to give notification of any defect or irregularity in connection with the submission of Subscription Certificates or incur any liability for failure to give such notification.

Subscription Certificates will only be mailed to Record Date Shareholders of record whose addresses are within the United States (other than an APO or FPO address). Because the Rights offering will not be registered in any jurisdiction other than the United States, the Rights Agent will attempt to sell all of the Rights issued to shareholders of record outside of these jurisdictions and remit the net proceeds, if any, to such shareholders of record. If the Rights can be sold, sales of these Rights will be deemed to have been effected at the weighted average price received by the Rights Agent on the day the Rights are sold, less any applicable brokerage commissions, taxes and other expenses.

The Fund has, pursuant to the SEC’s regulatory requirements, undertaken to suspend the Rights offering until the Fund amends this Prospectus Supplement if, after [•], 2020 (the date of this Prospectus Supplement), the Fund’s NAV declines more than 10% from the Fund’s NAV as of that date. In that event, the Expiration Date will be extended and the Fund will notify Record Date Shareholders of record of any such decline and permit Rights holders to cancel their exercise of Rights.

[Holders of Rights that are employee benefit plans subject to limitations imposed by the Internal Revenue Code of 1986, as amended (the “Code”), such as employee plans subject to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), Keogh Plans and Individual Retirement Accounts (“IRA”) (each a “Benefit Plan” and collectively, “Benefit Plans”), should be aware that the use of additional contributions of cash outside of the Benefit Plan to exercise Rights may be treated as additional contributions to the Benefit Plan. When taken together with contributions previously made, such deemed additional contributions may be in excess of tax limitations and subject the Rights holder to excise taxes for excess or nondeductible contributions. In the case of Benefit Plans qualified under Section 401(a) of the Code, additional contributions could cause the maximum contribution limitations of Section 415 of the Code or other qualification rules to be violated. Benefit Plans contemplating making additional contributions to exercise Rights should consult with their legal and tax counsel prior to making such contributions.

Benefit Plans and other tax exempt entities, including governmental plans, should also be aware that if they borrow to finance their exercise of Rights, they may become subject to the tax on unrelated business taxable income (“UBTI”) under Section 511 of the Code. If any portion of an IRA is used as security for a loan, the portion so used may also be treated as distributed to the IRA depositor.

A Benefit Plan may also be subject to laws, such as ERISA, that impose certain requirements on the Benefit Plan and on those persons who are fiduciaries with respect to the Benefit Plans (the “Benefit Plan Fiduciary”). Such requirements may include prudence and diversification requirements and require that investments be made in accordance with the documents governing the Benefit Plan. The exercise of Rights by a Benefit Plan Fiduciary for a Benefit Plan should be considered in light of such fiduciary requirements.

In addition, ERISA and the Code prohibit certain transactions involving the assets of a Benefit Plan and certain persons (referred to as “parties in interest” for purposes of ERISA and “disqualified persons” for purposes of the Code) having certain relationships to such Benefit Plans, unless a statutory or administrative exemption is applicable to the transaction. A party in interest or disqualified person who engages in a nonexempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code (or with respect to certain Benefit Plans, such as IRAs, a prohibited transaction may cause the Benefit Plan to lose its tax-exempt status). In this regard, the U.S. Department of Labor has issued prohibited transaction class exemptions (“PTCEs”) that may apply to the exercise of the Rights and holding of the Common Shares. These class exemptions include, without limitation, PTCE 84-14 respecting transactions determined by independent

qualified professional asset managers, PTCE 90-1 respecting insurance company pooled separate accounts, PTCE 91-38 respecting bank collective investment funds, PTCE 95-60 respecting life insurance company general accounts and PTCE 96-23 respecting transactions determined by in-house asset managers, PTCE 84-24 governing purchases of shares in investment companies) and PTCE 75-1 respecting sales of securities. In addition, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code each provides a limited exemption, commonly referred to as the “service provider exemption,” from the prohibited transaction provisions of ERISA and Section 4975 of the Code for certain transactions between a Benefit Plan and a person that is a party in interest and/or a disqualified person (other than a fiduciary or an affiliate that, directly or indirectly, has or exercises any discretionary authority or control or renders any investment advice with respect to the assets of any Benefit Plan involved in the transaction) solely by reason of providing services to the Benefit Plan or by relationship to a service provider, provided that the Benefit Plan receives no less, nor pays no more, than adequate consideration. There can be no assurance that all of the conditions of any such exemptions or any other exemption will be satisfied at the time that the Rights are exercised, or thereafter while the Common Shares are held, if the facts relied upon for using a prohibited transaction exemption change.

By its exercise of the Rights, each Benefit Plan will be deemed to have represented and warranted that (i) neither the exercise of the Rights, nor the investment in Common Shares pursuant to such exercise, will result in a non-exempt prohibited transaction under ERISA or Section 4975 of the Code, or any substantially similar law, and (ii) neither the Advisor, the Dealer Manager, the Fund or any of their affiliates is or will be a Benefit Plan Fiduciary with respect to the Benefit Plan’s exercise of the Rights or its investment in Common Shares, for purposes of ERISA and Section 4975 of the Code, or any applicable substantially similar law.

Due to the complexity of these rules and the penalties for noncompliance, fiduciaries of Benefit Plans, including the Benefit Plan Fiduciary, should consult with their legal and tax counsel regarding the consequences of their exercise of Rights under ERISA, the Code and other similar laws.]

The following table and example are intended to assist you in understanding the various costs and expenses directly or indirectly associated with investing in our Common Shares as a percentage of net assets attributable to Common Shares. Amounts are for the current fiscal year after giving effect to anticipated net proceeds of the Rights offering, assuming that we incur the estimated offering expenses.

The purpose of the table above and the examples below is to help you understand all fees and expenses that you, as a holder of Common Shares, would bear directly or indirectly.

The Fund estimates the net proceeds of the Rights offering to be approximately $[●], based on the estimated Subscription Price per Common Share of $[●] ([●]% of the last reported sales price of the Fund’s Common Shares on the NYSE on [●], 2020), assuming all new Common Shares offered are sold and that the expenses related to the Rights offering estimated at approximately $[●] are paid.

The net proceeds from the Rights offering hereunder will be invested in accordance with the Fund’s investment objective and policies as set forth in this Prospectus Supplement and the accompanying Prospectus. We currently anticipate that we will be able to invest all of the net proceeds in accordance with our investment objective and policies within approximately three months of the receipt of such proceeds. Pending such investment, it is anticipated that the proceeds will be invested in short-term investment grade securities or in high

quality, short-term money market instruments. Depending on market conditions and operations, a portion of the cash held by the Fund, including any proceeds raised from the offering, may be used to pay distributions in accordance with the Fund’s distribution policy and may be a return of capital. A return of capital is a return to investors of a portion of their original investment in the Fund. In general terms, a return of capital would involve a situation in which a Fund distribution (or a portion thereof) represents a return of a portion of a shareholder’s investment in the Fund, rather than making a distribution that is funded from the Fund’s earned income or other profits. Although return of capital distributions may not be currently taxable, such distributions would decrease the basis of a shareholder’s shares, and therefore, may increase a shareholder’s tax liability for capital gains upon a sale of shares, even if sold at a loss to the shareholder’s original investments.

The following table sets forth the unaudited capitalization of the Fund as of [•], 2020 and its adjusted capitalization assuming the Common Shares available in the Rights offering discussed in this Prospectus Supplement had been issued.

Risk is inherent in all investing. Therefore, before investing in the Common Shares you should consider the risks associated with such an investment carefully. See “Risks” in the Prospectus. The following summarizes some of the matters that you should consider before investing in the Fund through the Rights offering:

Dilution. Record Date Shareholders who do not fully exercise their Rights will, at the completion of the Rights offering, own a smaller proportional interest in the Fund than owned prior to the Rights offering. The completion of the Rights offering will result in immediate voting dilution for such shareholders. Further, both the sales load and the expenses associated with the Rights offering will immediately reduce the NAV of each outstanding Common Share. In addition, if the Subscription Price is less than the NAV per Common Share as of the Expiration Date, the completion of this Rights offering will result in an immediate dilution of the NAV per Common Share for all existing Common Shareholders (i.e., will cause the NAV per Common Share to decrease). It is anticipated that existing Common Shareholders will experience immediate dilution even if they fully exercise their Rights. Such dilution is not currently determinable because it is not known how many Common Shares will be subscribed for, what the NAV per Common Share or market price of the Common Shares will be on the Expiration Date or what the Subscription Price per Common Share will be. If the Subscription Price is substantially less than the current NAV per Common Share, this dilution could be substantial. The Fund will pay expenses associated with the Rights offering, estimated at approximately $[●]. In addition, the Fund has agreed to pay a dealer manager fee (sales load) equal to [●]% of the Subscription Price per Common Share issued pursuant to the exercise of Rights (including pursuant to the Over-Subscription Privilege). The Fund, not investors, pays the sales load, which is ultimately borne by all Common Shareholders. All of the costs of the Rights offering will be borne by the Fund’s Common Shareholders. See “Table of Fees and Expenses” in this Prospectus Supplement and “Summary of Fund Expenses” in the accompanying Prospectus for more information.

If you do not exercise all of your Rights, you may own a smaller proportional interest in the Fund when the Rights offering is over. In addition, you will experience an immediate dilution of the aggregate NAV per

Common Share if you do not participate in the Rights offering and will experience a reduction in the NAV per Common Share whether or not you exercise your Rights, if the Subscription Price is below the Fund’s NAV per Common Share on the Expiration Date, because:

On the other hand, if the Subscription Price is above the Fund’s NAV per Common Share on the Expiration Date, you may experience an immediate accretion of the aggregate NAV per share of your Common Shares even if you do not exercise your Rights and an immediate increase in the NAV per Common Share whether or not you participate in the Rights offering, because:

[Furthermore, if you do not participate in the secondary over-subscription, if it is available, your percentage ownership will also be diluted.] The Fund cannot state precisely the amount of any dilution because it is not known at this time what the NAV per Common Share will be on the Expiration Date or what proportion of the Rights will be exercised. The impact of the Rights offering on NAV per Common Share is shown by the following examples, assuming the Rights offering is fully subscribed and a $[●] Subscription Price:

If you do not wish to exercise your Rights, you should consider selling them as set forth in this Prospectus Supplement. Any cash you receive from selling your Rights may serve as partial compensation for any possible dilution of your interest in the Fund. The Fund cannot give assurance, however, that a market for the Rights will develop or that the Rights will have any marketable value.

[The Fund’s largest shareholders could increase their percentage ownership in the Fund through the exercise of the primary subscription and over-subscription privilege.]

Risks of Investing in Rights. Shares of closed-end funds such as the Fund frequently trade at a discount to NAV. If the Formula Price is less than [●]% of NAV on the Expiration Date, then the Subscription Price will likely be greater than the market price of a Common Share on that date. In addition, the Formula Price, even if above [●]% of NAV, may be still above the market price of a Common Share on the Expiration Date. If either event occurs, the Rights will have no value, and a person who exercises Rights will experience an immediate loss of value.

Leverage. Leverage creates a greater risk of loss, as well as a potential for more gain, for the Common Shares than if leverage were not used. Following the completion of the Rights offering, the Fund’s amount of leverage outstanding will decrease. The leverage of the Fund as of [●], 2020 was approximately [●]% of the Fund’s Managed Assets. After the completion of the Rights offering, the amount of leverage outstanding is expected to decrease to approximately [●]% of the Fund’s Managed Assets. The use of leverage for investment purposes creates opportunities for greater total returns but at the same time increases risk. When leverage is employed, the NAV and market price of the Common Shares and the yield to holders of Common Shares may be more volatile. Any investment income or gains earned with respect to the amounts borrowed in excess of the interest due on the borrowing will augment the Fund’s income. Conversely, if the investment performance with respect to the amounts borrowed fails to cover the interest on such borrowings, the value of the Fund’s Common Shares may decrease more quickly than would otherwise be the case, and distributions on the Common Shares could be reduced or eliminated. Interest payments and fees incurred in connection with such borrowings will reduce the amount of net income available for distribution to holders of the Common Shares.

Because the fee paid to the Advisor is calculated on the basis of the Fund’s Managed Assets, which include the proceeds of leverage, the dollar amount of the management fee paid by the Fund to the Advisor will be higher (and the Advisor will be benefited to that extent) when leverage is used. The Advisor will use leverage only if it believes such action would result in a net benefit to the Fund’s shareholders after taking into account the higher fees and expenses associated with leverage (including higher management fees).

Increase in Share Price Volatility; Decrease in Share Price. The Rights offering may result in an increase in trading of the Common Shares, which may increase volatility in the market price of the Common Shares. The Rights offering may result in an increase in the number of shareholders wishing to sell their Common Shares, which would exert downward price pressure on the price of Common Shares.

Under-Subscription. It is possible that the Rights offering will not be fully subscribed. Under-subscription of the Rights offering would have an impact on the net proceeds of the Rights offering and whether the Fund achieves any benefits.

[The following is a general summary of the U.S. federal income tax consequences of the Rights offering to Record Date Shareholders who are U.S. persons for U.S. federal income tax purposes. The following summary supplements the discussion set forth in the accompanying Prospectus and SAI and is subject to the qualifications and assumptions set forth therein. The discussion set forth herein does not constitute tax advice and potential investors are urged to consult their own tax advisers to determine the tax consequences of investing in the Fund.

Please refer to the “Tax Matters” section in the Fund’s Prospectus and SAI for a description of the consequences of investing in the Common Shares of the Fund. Special tax considerations relating to this Rights offering are summarized below:

The foregoing is a general and brief summary of the provisions of the Code and the Treasury Regulations in effect as they directly govern the taxation of the Fund and its Common Shareholders, with respect to U.S. federal income taxation only. Other tax issues such as state and local taxation may apply. Investors are urged to consult their own tax advisors to determine the tax consequences of investing in the Fund. These provisions are subject to change by legislative or administrative action, and any such change may be retroactive.]

[●] will act as Dealer Manager for this Rights offering. Under the terms and subject to the conditions contained in the Dealer Manager Agreement among the Dealer Manager, the Fund and the Advisor, the Dealer Manager will provide financial structuring and solicitation services in connection with the Rights offering and will solicit the exercise of Rights and participation in the over-subscription privilege. The Rights offering is not contingent upon any number of Rights being exercised. The Dealer Manager will also be responsible for forming and managing a group of selling broker-dealers (each, a “Selling Group Member” and collectively, the “Selling Group Members”), whereby each Selling Group Member will enter into a Selling Group Agreement with the Dealer Manager to solicit the exercise of Rights and to sell Common Shares purchased by the Selling Group

Member from the Dealer Manager. In addition, the Dealer Manager will enter into a Soliciting Dealer Agreement with other soliciting broker-dealers (each, a “Soliciting Dealer” and collectively, the “Soliciting Dealers”) to solicit the exercise of Rights. See “—Compensation to Dealer Manager” for a discussion of fees and other compensation to be paid to the Dealer Manager, Selling Group Members and Soliciting Dealers in connection with the Rights offering.

The Fund and the Advisor have each agreed to indemnify the Dealer Manager for losses arising out of certain liabilities, including liabilities under the Securities Act. The Dealer Manager Agreement also provides that the Dealer Manager will not be subject to any liability to the Fund in rendering the services contemplated by the Dealer Manager Agreement except for any act of willful misfeasance, bad faith or gross negligence of the Dealer Manager or reckless disregard by the Dealer Manager of its obligations and duties under the Dealer Manager Agreement.

In order to seek to facilitate the trading market in the Rights for the benefit of non-exercising shareholders, and the placement of the Common Shares to new or existing investors pursuant to the exercise of the Rights, the Dealer Manager Agreement provides for special arrangements with the Dealer Manager. Under these arrangements, the Dealer Manager is expected to purchase Rights on the [●], as well as Rights received by the Rights Agent for sale by Record Date Stockholders and offered to the Dealer Manager and unexercised Rights of Record Date Shareholders whose record addresses are outside the United States that are held by the Subscription Agent and for which no instructions are received. The number of rights, if any, purchased by the Dealer Manager will be determined by the Dealer Manager in its sole discretion. The Dealer Manager is not obligated to purchase Rights or Common Shares as principal for its own account to facilitate the trading market for Rights or for investment purposes. Rather, its purchases are expected to be closely related to interest in acquiring Common Shares generated by the Dealer Manager through its marketing and soliciting activities. The Dealer Manager intends to exercise Rights purchased by it during the Subscription Period but prior to the Expiration Date. The Dealer Manager may exercise those Rights at its option on one or more dates, which are expected to be prior to the Expiration Date. The Subscription Price for the Common Shares issued through the exercise of Rights by the Dealer Manager prior to the Expiration Date will be the greater of [●]% of the last reported sale price of a Common Share on the NYSE on the date of exercise or [●]% of the last reported NAV of a Common Share on the date prior to the date of exercise. The price and timing of these exercises are expected to differ from those described herein for the Rights offering. The Subscription Price will be paid to the Fund and the dealer manager fee with respect to such proceeds will be paid by the Fund on the applicable settlement date(s) of such exercise(s).

In connection with the exercise of Rights and receipt of Common Shares, the Dealer Manager intends to offer those Common Shares for sale to the public and/or through a group of selling members it has established. The Dealer Manager may set the price for those Common Shares at any price that it determines, in its sole discretion. The Dealer Manager has advised that the price at which such Common Shares are offered is expected to be at or slightly below the closing price of the Common Shares on the NYSE on the date the Dealer Manager exercises Rights. No portion of the amount paid to the Dealer Manager or to a Selling Group Member from the sale of Common Shares in this manner will be paid to the Fund. If the sales price of the Common Shares is greater than the Subscription Price paid by the Dealer Manager for such Common Shares plus the costs to purchase Rights for the purpose of acquiring those Common Shares, the Dealer Manager will receive a gain. Alternatively, if the sales price of the Common Shares is less than the Subscription Price for such Common Shares plus the costs to purchase Rights for the purpose of acquiring those Common Shares, the Dealer Manager will incur a loss. The Dealer Manager will pay a concession to Selling Group Members in an amount equal to approximately [2.50]% of the aggregate price of the Common Shares sold by the respective Selling Group Member. Neither the Fund nor the Advisor has a role in setting the terms, including the sales price, on which the Dealer Manager offers for sale and sells Common Shares it has acquired through purchasing and exercising Rights or the timing of the exercise of Rights or sales of Common Shares by the Dealer Manager. Persons who purchase Common Shares from the Dealer Manager or the selling group will purchase shares at a price set by the Dealer Manager, which may be more or less than the Subscription Price, and at a time set by the Dealer Manager, which is expected to be prior to the Expiration Date.

The Dealer Manager may purchase Rights as principal or act as agent on behalf of its clients for the resale of such Rights. The Dealer Manager may realize gains (or losses) in connection with the purchase and sale of Rights and the sale of Common Shares, although such transactions are intended by the Dealer Manager to facilitate the trading market in the Rights and the placement of the Common Shares to new or existing investors pursuant to the exercise of the Rights. Any gains (or losses) realized by the Dealer Manager from the purchase and sale of Rights and the sale of Common Shares is independent of and in addition to its fee as Dealer Manager. The Dealer Manager has advised that any such gains (or losses) are expected to be immaterial relative to its fee as Dealer Manager.

Since neither the Dealer Manager nor persons who purchase Common Shares from the Dealer Manager or members of the selling group were Record Date Shareholders, they would not be able to participate in the over-subscription privilege.

Persons who purchase Common Shares from the Dealer Manager or the selling group will not purchase shares at the Subscription Price based on the formula price mechanism through which Common Shares will be sold in the Rights offering. Instead, those persons will purchase Common Shares at a price set by the Dealer Manager, which may be more or less than the Subscription Price, and will not have the uncertainty of waiting for the determination of the Subscription Price on the Expiration Date.

There is no limit on the number of Rights the Dealer Manager can purchase or exercise. Common Shares acquired by the Dealer Manager pursuant to the exercise of Rights acquired by it will reduce the number of Common Shares available pursuant to the over-subscription privilege, perhaps materially, depending on the number of Rights purchased and exercised by the Dealer Manager.

Although the Dealer Manager can seek to facilitate the trading market for Rights as described above, investors can acquire Common Shares at the Subscription Price by acquiring Rights on the [●] and exercising them in the method described above under “Description of the Rights—Method of Exercise of Rights” and “Description of the Rights—Payment for Shares.”

In the ordinary course of their businesses, the Dealer Manager and/or its affiliates may engage in investment banking or financial transactions with the Fund, the Advisor and their affiliates. In addition, in the ordinary course of their businesses, the Dealer Manager and/or its affiliates may, from time to time, own securities of the Fund or its affiliates.

Pursuant to the Dealer Manager Agreement, the Fund has agreed to pay the Dealer Manager a fee for its financial structuring and solicitation services equal to [●]% of the Subscription Price per Common Share for each Common Share issued pursuant to the exercise of Rights, including the over-subscription privilege.

The Dealer Manager will reallow to Selling Group Members in the selling group to be formed and managed by the Dealer Manager selling fees equal to [●]% of the Subscription Price for each Common Share issued pursuant to the Rights offering or the over-subscription privilege as a result of their selling efforts. In addition, the Dealer Manager will reallow to Soliciting Dealers that have executed and delivered a Soliciting Dealer Agreement and have solicited the exercise of Rights, solicitation fees equal to [●]% of the Subscription Price for each Common Share issued pursuant to the exercise of Rights as a result of their soliciting efforts, subject to a maximum fee based on the number of Common Shares held by such Soliciting Dealer through [insert depository] on the Record Date. Fees will be paid to the broker-dealer designated on the applicable portion of the subscription certificates or, in the absence of such designation, to the Dealer Manager.

In addition, the Fund, has agreed to pay the Dealer Manager an amount up to $[●] as a partial reimbursement of its expenses incurred in connection with the Rights offering, including reasonable out-of-pocket fees and expenses, if any and not to exceed $[●], incurred by the Dealer Manager, Selling Group Members, Soliciting Dealers and other brokers, dealers and financial institutions in connection with their customary mailing and handling of materials related to the Rights offering to their customers. No other fees will be payable by the Fund or the Advisor to the Dealer Manager in connection with the Rights offering.

The Fund is a diversified, closed-end management investment company registered under the Investment Company Act. The Fund was organized as a Maryland corporation on April 15, 1993, pursuant to the Fund’s Articles of Incorporation (the “Charter”), which are governed by the laws of the State of Maryland. The Fund’s investment adviser is BlackRock Advisors, LLC (the “Advisor”).

The common shares of the Fund are listed on the New York Stock Exchange (“NYSE”) under the symbol “MUA.” As of [●], 2020, the Fund has outstanding [●] common shares.

The Fund has adopted restrictions and policies relating to the investment of the Fund’s assets and its activities. Certain of the restrictions are fundamental policies of the Fund and may not be changed without the approval of the holders of a majority of the Fund’s outstanding voting securities (which for this purpose and under the Investment Company Act means the lesser of (i) 67% of the shares represented at a meeting at which more than 50% of the outstanding shares are represented or (ii) more than 50% of the outstanding shares), including class approval by a majority of the Fund’s outstanding shares of preferred stock (“preferred shares”), if any (which for this purpose and under the Investment Company Act means the lesser of (i) 67% of the preferred shares, as a single class, represented at a meeting at which more than 50% of the Fund’s outstanding preferred shares are represented or (ii) more than 50% of the outstanding preferred shares).

Fundamental Investment Restrictions. Under these fundamental investment restrictions, the Fund may not:

For purposes of restriction (6), the exception for states, municipalities and their political subdivisions applies only to tax-exempt securities issued by such entities.

Non-Fundamental Investment Restrictions. Additional investment restrictions adopted by the Fund, which may be changed by the Fund’s Board of Directors (the “Board”) without shareholder approval, provide that the Fund may not:

[In addition, in order to comply with Federal tax requirements for qualification as a “regulated investment company,” the Fund’s investments will be limited in a manner such that at the close of each quarter of each taxable year, (i) not more than 25% of the market value of the Fund’s total assets will be invested in (A) the securities of a single issuer (other than U.S. Government securities and securities of other regulated investment companies), (B) the securities of two or more issuers (other than securities of other regulated investment companies) controlled by the Fund and engaged in the same, similar or related trades or businesses or (C) the securities of one or more qualified publicly traded partnerships and (ii) with respect to 50% of the market value of its total assets, not more than 5% of the market value of its total assets will be invested in the securities of a single issuer and the Fund will not own more than 10% of the outstanding voting securities of a single issuer (other than U.S. Government securities and securities of other regulated investment companies). These tax-related limitations may be changed by the Board to the extent appropriate in light of changes to applicable tax requirements.]

Unless otherwise indicated, all limitations under the Fund’s fundamental or non-fundamental investment restrictions apply only at the time that a transaction is undertaken. Any change in the percentage of the Fund’s assets invested in certain securities or other instruments resulting from market fluctuations or other changes in the Fund’s total assets will not require the Fund to dispose of an investment until the Advisor determines that it is practicable to sell or close out the investment without undue market or tax consequences.

Any policies of the Fund not described as fundamental in the Prospectus or this Statement of Additional Information may be changed by the Board without shareholder approval.

The following information supplements the discussion of the Fund’s investment objective, policies and techniques that are described in the prospectus.

The Fund may invest in investments that lack an established secondary trading market or otherwise are considered illiquid. 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 may trade at a discount from comparable, more liquid investments. 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. The risks associated with illiquidity will be particularly acute where the Fund’s operations require cash, such as when the Fund pays dividends, and could result in the Fund borrowing to meet short-term cash requirements or incurring capital losses on the sale of illiquid investments.

The Fund may invest in securities that are not registered under the Securities Act (“restricted securities”). Restricted securities may be sold in private placement transactions between issuers and their purchasers and may be neither listed on an exchange nor traded in other established markets. In many cases, privately placed securities may not be freely transferable under the laws of the applicable jurisdiction or due to contractual restrictions on resale. As a result of the absence of a public trading market, privately placed securities may be less liquid and more difficult to value than publicly traded securities. To the extent that privately placed securities may be resold in privately negotiated transactions, the prices realized from the sales, due to illiquidity, could be less than those originally paid by the Fund or less than their fair market value. In addition, issuers whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements that may be applicable if their securities were publicly traded. If any privately placed securities held by the Fund are required to be registered under the securities laws of one or more jurisdictions before being resold, the Fund may be required to bear the expenses of registration. Where registration is required for restricted securities, a considerable time period may elapse between the time the Fund decides to sell the security and the time it is actually permitted to sell the security under an effective registration statement. If during such period, adverse market conditions were to develop, the Fund might obtain less favorable pricing terms than when it decided to sell the security. Transactions in restricted securities may entail other transaction costs that are higher than those for transactions in unrestricted securities. Certain of the Fund’s investments in private placements may consist of direct investments and may include investments in smaller, less seasoned issuers, which may involve greater risks. These issuers may have limited product lines, markets or financial resources, or they may be dependent on a limited management group. In making investments in such securities, the Fund may obtain access to material nonpublic information, which may restrict the Fund’s ability to conduct portfolio transactions in such securities.

As described in the prospectus, the Fund may use Strategic Transactions (as defined in the prospectus). This section contains various additional information about the type of Strategic Transactions in which the Fund may engage.

Swaps and Swaptions. 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”). The Fund’s obligations under a swap agreement will be accrued daily (offset against any amounts owing to the Fund) and the Fund will segregate with a custodian or earmark on its books and records an amount of cash or liquid assets having an aggregate NAV at all times at least equal to any accrued but unpaid net amounts owed to a swap counterparty.

Whether the Fund’s use of swap agreements will be successful in furthering its investment objective will depend on the Advisor’s 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. As noted, however, the Fund will deposit in a segregated account, or earmark on its books and records, liquid assets permitted to be so segregated or earmarked by the SEC in an amount equal to or greater than the market value of the Fund’s liabilities under the swap agreement or the amount it would cost the Fund initially to make an equivalent direct investment plus or minus any amount the Fund is obligated to pay or is to receive under the swap agreement. Restrictions imposed by the tax rules applicable to RICs 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.

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 will generally incur a greater degree of risk when it writes a swaption than it will incur when it purchases a swaption. 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.

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.

Total return swap agreements are subject to 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). The net amount of the excess, if any, of the Fund’s obligations over its entitlements with respect to each total return swap will be accrued on a daily basis, and an amount of liquid assets having an aggregate net asset value (“NAV”) at least equal to the accrued excess will be segregated by the Fund or earmarked on its books and records. If the total return swap transaction is entered into on other than a net basis, the full amount of the Fund’s obligations will be accrued on a daily basis, and the full amount of the Fund’s obligations will be segregated or earmarked by the Fund in an amount equal to or greater than the market value of the liabilities under the total return swap agreement or the amount it would have cost the Fund initially to make an equivalent direct investment, plus or minus any amount the Fund is obligated to pay or is to receive under the total return swap agreement.

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”) for purposes of hedging against the decline in the value of currencies in which its portfolio holdings are denominated against the U.S. dollar or may seek to enhance returns. 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 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 Advisor believes 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 purchase forward currency contracts to enhance income when the Advisor anticipates 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 Advisor anticipates 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 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 assurances 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, and would continue to be required to maintain a position in securities denominated in the foreign currency or to maintain cash or liquid assets in a segregated account or earmark such cash or liquid assets on its books and records. 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.

Use of Options as Strategic Transactions. The Fund may also use options as Strategic Transactions.

Call Options as Strategic Transactions. 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. 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. Covered call options also serve as a partial hedge to the extent of the premium received against the price of the underlying security declining. The Fund may not write covered call options on underlying securities in an amount exceeding 15% of the market value of its total assets.

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. In addition, in connection with each such transaction the Fund will segregate, or designate on its books and records, liquid assets or cash with a value at least equal to the Fund’s exposure (the difference between the unpaid amounts owed by the Fund on such transaction minus any collateral deposited with the broker-dealer), on a marked-to-market basis (as calculated pursuant to requirements of the SEC). Such segregation or earmarking will ensure that the Fund has assets available to satisfy its obligations with respect to the transaction and will avoid any potential leveraging of the Fund’s portfolio. Such designation will not limit the Fund’s exposure to loss. 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 as Strategic Transactions. 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 will not purchase options on securities if, as a result of such purchase, the aggregate cost of all outstanding options on securities held by that Fund would exceed 5% of the market value of the Fund’s total assets.

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 connection with such transaction, the Fund will segregate or designate on its books and records liquid assets or cash with a value at least equal to the Fund’s exposure, on a marked-to-market basis (as calculated pursuant to requirements of the SEC). Such designation will ensure that the Fund has assets available to satisfy its obligations with respect to the transaction and will avoid any potential leveraging of the Fund’s portfolio. Such designation will not limit the Fund’s exposure to loss.

The Fund will not sell puts if, as a result, more than 50% of the Fund’s total assets would be required to cover its potential obligations under its hedging and other investment transactions. 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.

Futures Contracts and Options on Futures Contracts. The Fund may engage in transactions in financial futures contracts (“futures contracts”) and related options on such futures contracts. A futures contract is an agreement between two parties which obligates the purchaser of the futures contract to buy and the seller of a futures contract to sell a security for a set price on a future date or, in the case of an index futures contract, to make and accept a cash settlement based upon the difference in value of the index between the time the contract was entered into and the time of its settlement. 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 “contract markets” by the CFTC.

The Fund may sell financial futures contracts in anticipation of an increase in the general level of interest rates. Generally, as interest rates rise, the market values of securities that may be held by the Fund will fall, thus reducing the NAV of the Fund. However, as interest rates rise, the value of the Fund’s short position in the futures contract also will tend to increase, thus offsetting all or a portion of the depreciation in the market value of the Fund’s investments which are being hedged. While the Fund will incur commission expenses in selling and closing out futures positions, these commissions are generally less than the transaction expenses which the Fund would have incurred had the Fund sold portfolio securities in order to reduce its exposure to increases in interest rates. The Fund also may purchase financial futures contracts in anticipation of a decline in interest rates when it is not fully invested in a particular market in which it intends to make investments to gain market exposure that may in part or entirely offset an increase in the cost of securities it intends to purchase. It is anticipated that, in a substantial majority of these transactions, the Fund will purchase securities upon termination of the futures contract.

The Fund may purchase and write call and put options on futures contracts. Options on futures contracts are similar to options on securities except that an option on a futures contract gives the purchaser the right in return for the premium paid to assume a position in a futures contract (a long position if the option is a call and a short

position if the option is a put). Generally, these strategies are utilized under the same market and market sector conditions (i.e., conditions relating to specific types of investments) in which the Fund enters into futures transactions. The Fund may purchase put options or write call options on futures contracts rather than selling the underlying futures contract in anticipation of a decrease in the market value of securities or an increase in interest rates. Similarly, the Fund may purchase call options, or write put options on futures contracts, as a substitute for the purchase of such futures to hedge against the increased cost resulting from an increase in the market value or a decline in interest rates of securities which the Fund intends to purchase.

The Fund may engage in options and futures transactions on exchanges and options in the OTC markets. In general, exchange-traded contracts are third-party contracts (i.e., performance of the parties’ obligation is guaranteed by an exchange or clearing corporation) with standardized strike prices and expiration dates. OTC options transactions are two-party contracts with price and terms negotiated by the buyer and seller. See “—Additional Information About Options,” below.

At the time a futures contract is purchased or sold, the Fund must allocate cash or securities as a deposit payment (“initial margin”). It is expected that the initial margin that the Fund will pay may range from approximately 1% to approximately 5% of the value of the securities or commodities underlying the contract. In certain circumstances, however, such as periods of high volatility, the Fund may be required by an exchange to increase the level of its initial margin payment. Additionally, initial margin requirements may be increased generally in the future by regulatory action. An outstanding futures contract is valued daily and the payment in case of “variation margin” may be required, a process known as “marking to the market.” Transactions in listed options and futures are usually settled by entering into an offsetting transaction, and are subject to the risk that the position may not be able to be closed if no offsetting transaction can be arranged.

When the Fund purchases a futures contract or writes a put option or purchases a call option thereon, an amount of cash or liquid assets will be segregated or designated on the Fund’s books and records so that the amount so designated, plus the amount of variation margin held in the account of its broker, equals the market value of the futures contract, thereby ensuring that the use of such futures is unleveraged.

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 OTC options which are privately negotiated with the counterparty. Listed options are issued by the OCC, which guarantees the performance of the obligations of 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 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 are considered by the staff of the SEC to 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.

Restrictions on OTC Options. The Fund will engage in OTC options only with member banks of the Federal Reserve System and primary dealers in U.S. Government securities or with affiliates of such banks or dealers that have capital of at least $50 million or whose obligations are guaranteed by an entity having capital of at least $50 million. OTC options and assets used to cover OTC options written by the Fund may be considered to 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.

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 Advisor; 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.”

The Fund’s use of derivative instruments involves risks different from, and possibly greater than, the risks associated with investing directly in securities and other traditional investments. Derivatives are subject to a number of risks such as credit risk, leverage risk, illiquidity risk, correlation risk and index risk as described below:

When a derivative is used as a hedge against a position that the Fund holds, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund’s hedging transactions will be effective. The Fund could also suffer losses related to its derivative positions as a result of unanticipated market movements, which losses are potentially unlimited. The Advisor may not be able to predict correctly the direction of securities prices, interest rates and other economic factors, which could cause the Fund’s derivatives positions to lose value. In addition, some derivatives are more sensitive to interest rate changes and market price fluctuations than other securities. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately.

When engaging in a hedging transaction, the Fund may determine not to seek to establish a perfect correlation between the hedging instruments utilized and the portfolio holdings being hedged. Such an imperfect correlation may prevent the Fund from achieving the intended hedge or expose the Fund to a risk of loss. The Fund may also determine not to hedge against a particular risk because it does not regard the probability of the risk occurring to be sufficiently high as to justify the cost of the hedge or because it does do not foresee the occurrence of the risk. It may not be possible for the Fund to hedge against a change or event at attractive prices or at a price sufficient to protect the assets of the Fund from the decline in value of the portfolio positions anticipated as a result of such change. The Fund may also be restricted in its ability to effectively manage the portion of its assets that are segregated or earmarked to cover its obligations. In addition, it may not be possible to hedge at all against certain risks.

If the Fund invests in a derivative instrument it could lose more than the principal amount invested. Moreover, derivatives raise certain tax, legal, regulatory and accounting issues that may not be presented by investments in securities, and there is some risk that certain issues could be resolved in a manner that could adversely impact the performance of the Fund.

The Fund is not required to use derivatives or other portfolio strategies to seek to increase return or to seek to hedge its portfolio and may choose not to do so. Also, suitable derivative transactions may not be available in

all circumstances and there can be no assurance that the Fund will engage in these transactions to reduce exposure to other risks when that would be beneficial. Although the Advisor seeks to use derivatives to further the Fund’s investment objective, there is no assurance that the use of derivatives will achieve this result.

Options Risk. There are several risks associated with transactions in options on securities and indexes. For example, there are significant differences between the securities and options markets that could result in an imperfect correlation between these markets, causing a given transaction not to achieve its objective. In addition, a liquid secondary market for particular options, whether traded OTC or on a recognized securities exchange (e.g., NYSE), separate trading boards of a securities exchange or through a market system that provides contemporaneous transaction pricing information (an “Exchange”) may be absent for reasons which include the following: there may be insufficient trading interest in certain options; restrictions may be imposed by an Exchange on opening transactions or closing transactions or both; trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options or underlying securities; unusual or unforeseen circumstances may interrupt normal operations on an Exchange; the facilities of an Exchange or the OCC may not at all times be adequate to handle current trading volume; or one or more Exchanges could, for economic or other reasons, decide or be compelled at some future date 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 that had been issued by the OCC as a result of trades on that Exchange would continue to be exercisable in accordance with their terms.

Futures Transactions and Options Risk. The primary risks associated with the use of futures contracts and options are (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract or option; (b) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Advisor’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; and (e) the possibility that the counterparty will default in the performance of its obligations.

Investment in futures contracts involves the risk of imperfect correlation between movements in the price of the futures contract and the price of the security being hedged. The hedge will not be fully effective when there is imperfect correlation between the movements in the prices of two financial instruments. For example, if the price of the futures contract moves more or less than the price of the hedged security, the Fund will experience either a loss or gain on the futures contract which is not completely offset by movements in the price of the hedged securities. To compensate for imperfect correlations, the Fund may purchase or sell futures contracts in a greater dollar amount than the hedged securities if the volatility of the hedged securities is historically greater than the volatility of the futures contracts. Conversely, the Fund may purchase or sell fewer futures contracts if the volatility of the price of the hedged securities is historically lower than that of the futures contracts.

The particular securities comprising the index underlying a securities index financial futures contract may vary from the securities held by the Fund. As a result, the Fund’s ability to hedge effectively all or a portion of the value of its securities through the use of such financial futures contracts will depend in part on the degree to which price movements in the index underlying the financial futures contract correlate with the price movements of the securities held by the Fund. The correlation may be affected by disparities in the average maturity, ratings, geographical mix or structure of the Fund’s investments as compared to those comprising the securities index and general economic or political factors. In addition, the correlation between movements in the value of the securities index may be subject to change over time as additions to and deletions from the securities index alter its structure. The correlation between futures contracts on U.S. Government securities and the securities held by the Fund may be adversely affected by similar factors and the risk of imperfect correlation between movements in the prices of such futures contracts and the prices of securities held by the Fund may be greater. The trading of futures contracts also is subject to certain market risks, such as inadequate trading activity, which could at times make it difficult or impossible to liquidate existing positions.

The Fund may liquidate futures contracts it enters into through offsetting transactions on the applicable contract market. There can be no assurance, however, that a liquid secondary market will exist for any particular futures contract at any specific time. Thus, it may not be possible to close out a futures position. In the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin. In such situations, if the Fund has insufficient cash, it may be required to sell portfolio securities to meet daily variation margin requirements at a time when it may be disadvantageous to do so. The inability to close out futures positions also could have an adverse impact on the Fund’s ability to hedge effectively its investments in securities. The liquidity of a secondary market in a futures contract may be adversely affected by “daily price fluctuation limits” established by commodity exchanges which limit the amount of fluctuation in a futures contract price during a single trading day. Once the daily limit has been reached in the contract, no trades may be entered into at a price beyond the limit, thus preventing the liquidation of open futures positions. Prices have in the past moved beyond the daily limit on a number of consecutive trading days.

The successful use of transactions in futures and related options also depends on the ability of the Advisor to forecast correctly the direction and extent of interest rate movements within a given time frame. To the extent interest rates remain stable during the period in which a futures contract or option is held by the Fund or such rates move in a direction opposite to that anticipated, the Fund may realize a loss on the Strategic Transaction which is not fully or partially offset by an increase in the value of portfolio securities. As a result, the Fund’s total return for such period may be less than if it had not engaged in the Strategic Transaction.

Because of low initial margin deposits made upon the opening of a futures position, futures transactions involve substantial leverage. As a result, relatively small movements in the price of the futures contracts can result in substantial unrealized gains or losses. There is also the risk of loss by the Fund of margin deposits in the event of bankruptcy of a broker with which the Fund has an open position in a financial futures contract. Because the Fund will engage in the purchase and sale of futures contracts for hedging purposes or to seek to enhance the Fund’s return, any losses incurred in connection therewith may, if the strategy is successful, be offset in whole or in part by increases in the value of securities held by the Fund or decreases in the price of securities the Fund intends to acquire.

The amount of risk the Fund assumes when it purchases an option on a futures contract is the premium paid for the option plus related transaction costs. In addition to the correlation risks discussed above, the purchase of an option on a futures contract also entails the risk that changes in the value of the underlying futures contract will not be fully reflected in the value of the option purchased.

General Risk Factors in Hedging Foreign Currency. Hedging transactions involving Currency Instruments involve substantial risks, including correlation risk. While the Fund’s use of Currency Instruments to effect hedging strategies is intended to reduce the volatility of the NAV of the Fund’s common shares, the NAV of the Fund’s common shares will fluctuate. Moreover, although Currency Instruments may be used with the intention of hedging against adverse currency movements, transactions in Currency Instruments involve the risk that anticipated currency movements will not be accurately predicted and that the Fund’s hedging strategies will be ineffective. To the extent that the Fund hedges against anticipated currency movements that do not occur, the Fund may realize losses and decrease its total return as the result of its hedging transactions. Furthermore, the Fund will only engage in hedging activities from time to time and may not be engaging in hedging activities when movements in currency exchange rates occur.

It may not be possible for the Fund to hedge against currency exchange rate movements, even if correctly anticipated, in the event that (i) the currency exchange rate movement is so generally anticipated that the Fund is not able to enter into a hedging transaction at an effective price, or (ii) the currency exchange rate movement relates to a market with respect to which Currency Instruments are not available and it is not possible to engage in effective foreign currency hedging. The cost to the Fund of engaging in foreign currency transactions varies with such factors as the currencies involved, the length of the contract period and the market conditions then prevailing. Since transactions in foreign currency exchange usually are conducted on a principal basis, no fees or commissions are involved.

Foreign Currency Forwards Risk. Forward foreign currency exchange contracts do not eliminate fluctuations in the value of Non-U.S. Securities (as defined in the prospectus) but rather allow the Fund to establish a fixed rate of exchange for a future point in time. This strategy can have the effect of reducing returns and minimizing opportunities for gain.

In connection with its trading in forward foreign currency contracts, the Fund will contract with a foreign or domestic bank, or foreign or domestic securities dealer, to make or take future delivery of a specified amount of a particular currency. There are no limitations on daily price moves in such forward contracts, and banks and dealers are not required to continue to make markets in such contracts. There have been periods during which certain banks or dealers have refused to quote prices for such forward contracts or have quoted prices with an unusually wide spread between the price at which the bank or dealer is prepared to buy and that at which it is prepared to sell. Governmental imposition of credit controls might limit any such forward contract trading. With respect to its trading of forward contracts, if any, the Fund will be subject to the risk of bank or dealer failure and the inability of, or refusal by, a bank or dealer to perform with respect to such contracts. Any such default would deprive the Fund of any profit potential or force the Fund to cover its commitments for resale, if any, at the then market price and could result in a loss to the Fund.

The Fund may also engage in proxy hedging transactions to reduce the effect of currency fluctuations on the value of existing or anticipated holdings of portfolio securities. Proxy hedging is often used when the currency to which the Fund is exposed is difficult to hedge or to hedge against the dollar. Proxy hedging entails entering into a forward contract to sell a currency whose changes in value are generally considered to be linked to a currency or currencies in which some or all of the Fund’s securities are, or are expected to be, denominated, and to buy U.S. dollars. Proxy hedging involves some of the same risks and considerations as other transactions with similar instruments. Currency transactions can result in losses to the Fund if the currency being hedged fluctuates in value to a degree or in a direction that is not anticipated. In addition, there is the risk that the perceived linkage between various currencies may not be present or may not be present during the particular time that the Fund is engaging in proxy hedging. The Fund may also cross-hedge currencies by entering into forward contracts to sell one or more currencies that are expected to decline in value relative to other currencies to which the Fund has or in which the Fund expects to have portfolio exposure. For example, the Fund may hold both Canadian government bonds and Japanese government bonds, and the Advisor may believe that Canadian dollars will deteriorate against Japanese yen. The Fund would sell Canadian dollars to reduce its exposure to that currency and buy Japanese yen. This strategy would be a hedge against a decline in the value of Canadian dollars, although it would expose the Fund to declines in the value of the Japanese yen relative to the U.S. dollar.

Some of the forward non-U.S. currency contracts entered into by the Fund may be classified as non-deliverable forwards (“NDFs”). NDFs are cash-settled, short-term forward contracts that may be thinly traded or are denominated in non-convertible foreign currency, where the profit or loss at the time at the settlement date is calculated by taking the difference between the agreed upon exchange rate and the spot rate at the time of settlement, for an agreed upon notional amount of funds. All NDFs have a fixing date and a settlement date. The fixing date is the date at which the difference between the prevailing market exchange rate and the agreed upon exchange rate is calculated. The settlement date is the date by which the payment of the difference is due to the party receiving payment. NDFs are commonly quoted for time periods of one month up to two years, and are normally quoted and settled in U.S. dollars. They are often used to gain exposure to and/or hedge exposure to foreign currencies that are not internationally traded.

Currency Futures Risk. The Fund may also seek to hedge against the decline in the value of a currency or to enhance returns through use of currency futures or options thereon. Currency futures are similar to forward foreign exchange transactions except that futures are standardized, exchange-traded contracts while forward foreign exchange transactions are traded in the OTC market. Currency futures involve substantial currency risk, and also involve leverage risk.

Currency Options Risk. The Fund may also seek to hedge against the decline in the value of a currency or to enhance returns through the use of currency options. Currency options are similar to options on securities. For

example, in consideration for an option premium the writer of a currency option is obligated to sell (in the case of a call option) or purchase (in the case of a put option) a specified amount of a specified currency on or before the expiration date for a specified amount of another currency. The Fund may engage in transactions in options on currencies either on exchanges or OTC markets. Currency options involve substantial currency risk, and may also involve credit, leverage or illiquidity risk.

Currency Swaps Risk. The Fund may enter into currency swaps, which are transactions in which one currency is simultaneously bought for a second currency on a spot basis and sold for the second currency on a forward basis. Currency swaps involve the exchange of the rights of the Fund and another party to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency in exchange for the other designated currency. Because currency swaps usually involve the delivery of the entire principal value of one designated currency in exchange for the other designated currency, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations.

Over-the-Counter Trading Risk. The derivative instruments that may be purchased or sold by the Fund may include instruments not traded on an exchange. The risk of nonperformance by the counterparty to an instrument may be greater than, and the ease with which the Fund can dispose of or enter into closing transactions with respect to an instrument may be less than, the risk associated with an exchange traded instrument. In addition, significant disparities may exist between “bid” and “asked” prices for derivative instruments that are not traded on an exchange. The absence of liquidity may make it difficult or impossible for the Fund to sell such instruments promptly at an acceptable price. Derivative instruments not traded on exchanges also are not subject to the same type of government regulation as exchange traded instruments, and many of the protections afforded to participants in a regulated environment may not be available in connection with the transactions. Because derivatives traded in OTC markets generally are not guaranteed by an exchange or clearing corporation and generally do not require payment of margin, to the extent that the Fund has unrealized gains in such instruments or has deposited collateral with its counterparties the Fund is at risk that its counterparties will become bankrupt or otherwise fail to honor its obligations.

Dodd-Frank Act Risk. Title VII of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) (the “Derivatives Title”) imposed a substantially new regulatory structure on derivatives markets, with particular emphasis on swaps and security-based swaps. This new regulatory framework covers a broad range of swap market participants, including banks, non-banks, credit unions, insurance companies, broker-dealers and investment advisers. Although the CFTC and the prudential regulators have adopted and implemented substantially all of the required regulations, the SEC has not yet implemented regulations governing security-based swaps. In October 2018, the SEC re-opened comments on its capital and margin requirements. Upon finalization of those rules together with the recordkeeping rules applicable in connection with security-based swaps and a compliance period (which has yet to be determined), the SEC requirements are expected to go into effect. As currently proposed, the SEC’s margin requirements for security-based swaps are substantially different from those applicable to swaps and margining requirements applicable to banks acting as counterparties for security-based swaps. These differences could result in additional costs to counterparties such as the Fund or constrict the size of the security-based swaps market. Current regulations for swaps require the mandatory central clearing and mandatory exchange trading of particular types of interest rate swaps and index credit default swaps (together, “Covered Swaps”). The Fund is required to clear its Covered Swaps through a clearing broker, which requires, among other things, posting initial margin and variation margin to the Fund’s clearing broker in order to enter into and maintain positions in Covered Swaps. Covered Swaps generally are required to be executed through a swap execution facility (“SEF”), which can involve additional transaction fees.

Additionally, under the Dodd-Frank Act, certain derivatives are subject to margin requirements and swap dealers are required to collect margin from the Fund with respect to such derivatives. Specifically, regulations are now in effect that require swap dealers to post and collect variation margin (comprised of specified liquid instruments and subject to a required haircut) in connection with trading of OTC swaps with the Fund. Shares of

investment companies (other than certain money market funds) may not be posted as collateral under these regulations. Requirements for posting of initial margin in connection with OTC swaps will be phased-in through 2020. The CFTC has not yet adopted capital requirements for swap dealers. As uncleared capital requirements for swap dealers and uncleared capital and margin requirements for security-based swaps have been and continue to be finalized and implemented, such requirements may make certain types of trades and/or trading strategies more costly or impermissible. There may be market dislocations due to uncertainty during the implementation period of any new regulation and the Advisor cannot know how the derivatives market will adjust to new regulations.

Legal and Regulatory Risk. At any time after the date hereof, legislation or additional regulations may be enacted that could negatively affect the assets of the Fund. Changing approaches to regulation may have a negative impact on the securities in which the Fund invests. Legislation or regulation may also change the way in which the Fund itself is regulated. There can be no assurance that future legislation, regulation or deregulation will not have a material adverse effect on the Fund or will not impair the ability of the Fund to achieve its investment objective. In addition, as new rules and regulations resulting from the passage of the Dodd-Frank Act are implemented and new international capital and liquidity requirements are introduced under the Basel III Accords, the market may not react the way the Advisor expects. Whether the Fund achieves its investment objective may depend on, among other things, whether the Advisor correctly forecasts market reactions to this and other legislation. In the event the Advisor incorrectly forecasts market reaction, the Fund may not achieve its investment objective.

Although the Advisor intends to devote such time and effort to the business of the Fund as is reasonably necessary to perform its duties to the Fund, the services of the Advisor are not exclusive and the Advisor provides similar services to other investment companies and other clients and may engage in other activities.

The investment management agreement between the Advisor and the Fund (the “Investment Management Agreement”) also provides that except for a loss resulting from a breach of fiduciary duty with respect to the receipt of compensation or a loss resulting from willful misfeasance, bad faith or gross negligence on the Advisor’s part in the performance of its duties or from reckless disregard by the Advisor of its duties under the Investment Management Agreement, the Advisor is not liable for any error of judgment or mistake of law or for any loss suffered by the Advisor or the Fund in connection with the performance of the Investment Management Agreement. The Investment Management Agreement also provides for indemnification by the Fund of the Advisor and each of the Advisor’s directors, officers, employees, agents, associates and controlling persons, and the directors, partners, members, officers, employees and agents thereof (including any individual who serves at the Advisor’s request as director, officer, partner, member, trustee or the like of another entity) for liabilities and expenses incurred by them in connection with their services to the Fund, subject to certain limitations and conditions.

The Investment Management Agreement provides for the Fund to pay a monthly management fee at an annual rate equal to 0.55% of the average daily value of the Fund’s net assets.

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 ETFs managed by the Advisor or its affiliates that have a contractual fee, through June 30, 2021. In addition, effective December 1, 2019, 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 advised by the Advisor or its affiliates, through June 30, 2021. The Fee Waiver Agreement may be continued from year to year thereafter, provided that such continuance is specifically approved by the Advisor and the Fund (including by a majority of the Directors who are not “interested persons” (as defined in the Investment Company Act) (the “Independent Directors”)). Neither the Advisor nor the Fund is obligated to extend the Fee Waiver Agreement. 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 Independent Directors or a majority of the outstanding voting securities of the Fund), upon 90 days’ written notice by the Fund to the Advisor. Prior to December 1, 2019, the agreement to waive a portion of the Fund’s management fee in connection with the Fund’s investment in affiliated money market funds was voluntary.

The Investment Management Agreement will continue in effect from year to year provided that each continuance is specifically approved at least annually by both (1) the vote of a majority of the Board or the vote of a majority of the outstanding voting securities of the Fund (as such term is defined in the Investment Company Act) and (2) by the vote of a majority of the Directors who are not parties to the Investment Management Agreement or “interested persons” (as such term is defined in the Investment Company Act) of any such party, cast in person at a meeting called for the purpose of voting on such approval. The Investment Management Agreement may be terminated as a whole at any time by the Fund, without the payment of any penalty, upon the vote of a majority of the Directors or a majority of the outstanding voting securities of the Fund or by the Advisor, on 60 days’ written notice by either party to the other which can be waived by the non-terminating party. The Investment Management Agreement will terminate automatically in the event of its “assignment” (as such term is defined in the Investment Company Act and the rules thereunder).

The table below sets forth information about the total management fees paid by the Fund to the Advisor, and the amounts waived by the Advisor, for the periods indicated:

The Board consists of ten individuals (each, a “Director”), eight of whom are Independent Directors. The registered investment companies advised by the Advisor or its affiliates (the “BlackRock-advised Funds”) are organized into one complex of closed-end funds and open-end non-index fixed-income funds (the “BlackRock Fixed-Income Complex”), one complex of open-end equity, multi-asset, index and money market funds (the “BlackRock Multi-Asset Complex”) and one complex of exchange-traded funds (each, a “BlackRock Fund Complex”). The Fund is included in the BlackRock Fund Complex referred to as the BlackRock Fixed-Income Complex. The Directors also oversee as board members the operations of the other open-end and closed-end registered investment companies included in the BlackRock Fixed-Income Complex.

Certain biographical and other information relating to the Directors of the Fund is set forth below, including their year of birth, their principal occupation for at least the last five years, the length of time served, the total number of BlackRock-advised Funds overseen and any public directorships or trusteeships.

The Independent Directors have adopted a statement of policy that describes the experiences, qualifications, skills and attributes that are necessary and desirable for potential Independent Director candidates (the “Statement of Policy”). The Board believes that each Independent Director satisfied, at the time he or she was initially elected or appointed a Director, and continues to satisfy, the standards contemplated by the Statement of Policy as well as the standards set forth in the Fund’s Bylaws. Furthermore, in determining that a particular Director was and continues to be qualified to serve as a Director, the Board has considered a variety of criteria, none of which, in isolation, was controlling. The Board believes that, collectively, the Directors have balanced and diverse experiences, skills, attributes and qualifications, which will allow the Board to operate effectively in governing the Fund and protecting the interests of shareholders. Among the attributes common to all Directors is their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Advisor, other service providers, counsel and independent auditors, and to exercise effective business judgment in the performance of their duties as Directors. Each Director’s ability to perform his or her duties effectively is evidenced by his or her educational background or professional training; business, consulting, public service or academic positions; experience from service as a board member of the Fund or the other funds in the BlackRock Fund Complexes (and any predecessor funds), other investment funds, public companies, or not-for-profit entities or other organizations; ongoing commitment and participation in Board and Committee meetings, as well as his or her leadership of standing and other committees of other BlackRock-advised Funds throughout the years; or other relevant life experiences.

The table below discusses some of the experiences, qualifications and skills of each Director that support the conclusion that he or she should serve on the Board.

The Board has overall responsibility for the oversight of the Fund. The Co-Chairs of the Board and the Chief Executive Officer are different people. Not only is each Co-Chair of the Board an Independent Director, but also the Chair of each Board committee (each, a “Committee”) is an Independent Director. The Board has five standing Committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee, a Performance Oversight Committee and an Executive Committee. The role of each Co-Chair of the Board is to preside over all meetings of the Board and to act as a liaison with service providers, officers, attorneys, and other Directors between meetings. The Chair of each Committee performs a similar role with respect to the Committee. The Co-Chairs of the Board or Chair of a Committee may also perform such other functions as may be delegated by the Board or the Committee from time to time. The Independent Directors meet regularly outside the presence of the Fund’s management, in executive sessions or with other service providers to the Fund. The Board has regular meetings five times a year, including a meeting to consider the approval of the Fund’s investment management agreement, and, if necessary, may hold special meetings before its next regular meeting. Each Committee meets regularly to conduct the oversight functions delegated to that Committee by the Board and reports its findings to the Board. The Board and each standing Committee conduct annual assessments of their oversight function and structure. The Board has determined that the Board’s leadership structure is appropriate because it allows the Board to exercise independent judgment over management and to allocate areas of responsibility among Committees and the Board to enhance oversight.

The Board decided to separate the roles of Chief Executive Officer from the Co-Chairs because it believes that having independent Co-Chairs:

The Board has engaged the Advisor to manage the Fund on a day-to-day basis. The Board is responsible for overseeing the Advisor, other service providers, the operations of the Fund and associated risks in accordance with the provisions of the Investment Company Act, state law, other applicable laws, the Fund’s Charter, and the Fund’s investment objective and strategies. The Board reviews, on an ongoing basis, the Fund’s performance, operations, and investment strategies and techniques. The Board also conducts reviews of the Advisor and its role in running the operations of the Fund.

Day-to-day risk management with respect to the Fund is the responsibility of the Advisor or other service providers (depending on the nature of the risk), subject to the supervision of the Advisor. The Fund is subject to a number of risks, including investment, compliance, operational and valuation risks, among others. While there are a number of risk management functions performed by the Advisor or other service providers, as applicable, it is not possible to eliminate all of the risks applicable to the Fund. Risk oversight is part of the Board’s general oversight of the Fund and is addressed as part of various Board and Committee activities. The Board, directly or through Committees, also reviews reports from, among others, management, the independent registered public accounting firm for the Fund, the Advisor, and internal auditors for the Advisor or its affiliates, as appropriate, regarding risks faced by the Fund and management’s or the service provider’s risk functions. The Committee system facilitates the timely and efficient consideration of matters by the Directors and facilitates effective oversight of compliance with legal and regulatory requirements and of the Fund’s activities and associated risks. The Board approved the appointment of a Chief Compliance Officer (“CCO”), who oversees the implementation and testing of the Fund’s compliance program and reports regularly to the Board regarding compliance matters

for the Fund and its service providers. The Independent Directors have engaged independent legal counsel to assist them in performing their oversight responsibilities.

Audit Committee. The Board has a standing Audit Committee composed of Michael J. Castellano (Chair), Frank J. Fabozzi, Catherine A. Lynch and Karen P. Robards, all of whom are Independent Directors. The principal responsibilities of the Audit Committee are to assist the Board in fulfilling its oversight responsibilities relating to the accounting and financial reporting policies and practices of the Fund. The Audit Committee’s responsibilities include, without limitation: (i) approving and recommending to the full Board for approval the selection, retention, termination and compensation of the Fund’s independent registered public accounting firm (the “Independent Registered Public Accounting Firm”) and evaluating the independence and objectivity of the Independent Registered Public Accounting Firm; (ii) approving all audit engagement terms and fees for the Fund; (iii) reviewing the conduct and results of each audit; (iv) reviewing any issues raised by the Fund’s Independent Registered Public Accounting Firm or management regarding the accounting or financial reporting policies and practices of the Fund, its internal controls, and, as appropriate, the internal controls of certain service providers and management’s response to any such issues; (v) reviewing and discussing the Fund’s audited and unaudited financial statements and disclosure in the Fund’s shareholder reports relating to the Fund’s performance; (vi) assisting the Board’s responsibilities with respect to the internal controls of the Fund and its service providers with respect to accounting and financial matters; and (vii) resolving any disagreements between the Fund’s management and the Fund’s Independent Registered Public Accounting Firm regarding financial reporting. The Board has adopted a written charter for the Board’s Audit Committee. A copy of the Audit Committee Charter for the Fund can be found in the “Corporate Governance” section of the BlackRock Closed-End Fund website at www.blackrock.com. During the fiscal year ended April 30, 2019, the Audit Committee met 13 times.

Governance and Nominating Committee. The Board has a standing Governance and Nominating Committee composed of R. Glenn Hubbard (Chair), Michael J. Castellano, Richard E. Cavanagh, Cynthia L. Egan and Karen P. Robards, all of whom are Independent Directors. The principal responsibilities of the Governance and Nominating Committee are: (i) identifying individuals qualified to serve as Independent Directors and recommending Board nominees that are not “interested persons” of the Fund (as defined in the Investment Company Act) for election by shareholders or appointment by the Board; (ii) advising the Board with respect to Board composition, procedures and Committees of the Board (other than the Audit Committee); (iii) overseeing periodic self-assessments of the Board and Committees of the Board (other than the Audit Committee); (iv) reviewing and making recommendations in respect to Independent Director compensation; (v) monitoring corporate governance matters and making recommendations in respect thereof to the Board; (vi) acting as the administrative committee with respect to Board policies and procedures, committee policies and procedures (other than the Audit Committee) and codes of ethics as they relate to the Independent Directors; and (vii) reviewing and making recommendations to the Board in respect of Fund share ownership by the Independent Directors. The Board has adopted a written charter for the Board’s Governance and Nominating Committee. During the fiscal year ended April 30, 2019, the Governance and Nominating Committee met 5 times.

The Governance and Nominating Committee of the Board seeks to identify individuals to serve on the Board who have a diverse range of viewpoints, qualifications, experiences, backgrounds and skill sets so that the Board will be better suited to fulfill its responsibility of overseeing the Fund’s activities. In so doing, the Governance and Nominating Committee reviews the size of the Board, the ages of the current Directors and their tenure on the Board, and the skills, background and experiences of the Directors in light of the issues facing the Fund in determining whether one or more new trustees should be added to the Board. The Board as a group strives to achieve diversity in terms of gender, race and geographic location. The Governance and Nominating Committee believes that the Directors as a group possess the array of skills, experiences and backgrounds necessary to guide the Fund. The Directors’ biographies included herein highlight the diversity and breadth of skills, qualifications and expertise that the Directors bring to the Fund.

The Governance and Nominating Committee may consider nominations for Directors made by the Fund’s shareholders as it deems appropriate. Under the Fund’s Bylaws, shareholders must follow certain procedures to

nominate a person for election as a Director at an annual or special meeting, or to introduce an item of business at an annual meeting. Under these advance notice procedures, shareholders must submit the proposed nominee or item of business by delivering a notice to the Secretary of the Fund at its principal executive offices. The Fund must receive notice of a shareholder’s intention to introduce a nomination or proposed item of business for an annual shareholder meeting not less than 120 days nor more than 150 days before the anniversary date of the prior year’s annual shareholder meeting. However, if the Fund holds its annual shareholder meeting on a date that is not within 25 days before or after the anniversary date of the prior year’s annual shareholder meeting, the Fund must receive the notice of a shareholder’s intention to introduce a nomination or proposed item of business not later than the close of business on the tenth day following the day on which the notice of the date of the shareholder meeting was mailed or the public disclosure of the date of the shareholder meeting was made, whichever comes first.

The Fund’s Bylaws provide that notice of a proposed nomination must include certain information about the shareholder and the nominee, as well as a written consent of the proposed nominee to serve if elected. A notice of a proposed item of business must include a description of and the reasons for bringing the proposed business to the meeting, any material interest of the shareholder in the business, and certain other information about the shareholder.

Further, the Fund has adopted Director qualification requirements which can be found in the Fund’s Bylaws and are applicable to all Directors that may be nominated, elected, appointed, qualified or seated to serve as Directors. The qualification requirements include: (i) age limits; (ii) limits on service on other boards; (iii) restrictions on relationships with investment advisers other than BlackRock; and (iv) character and fitness requirements. In addition to not being an “interested person” of the Fund as defined under Section 2(a)(19) of the Investment Company Act, each Independent Director may not be or have certain relationships with a shareholder owning five percent or more of the Fund’s voting securities or owning other percentage ownership interests in investment companies registered under the Investment Company Act. Reference is made to the Fund’s Bylaws for more details.

A copy of the Governance and Nominating Committee Charter for the Fund can be found in the “Corporate Governance” section of the BlackRock Closed-End Fund website at www.blackrock.com.

Compliance Committee. The Board has a Compliance Committee composed of Cynthia L. Egan (Chair), Richard E. Cavanagh, R. Glenn Hubbard and W. Carl Kester, all of whom are Independent Directors. The Compliance Committee’s purpose is to assist the Board in fulfilling its responsibility with respect to the oversight of regulatory and fiduciary compliance matters involving the Fund, the fund-related activities of BlackRock, and any subadviser and the Fund’s other third party service providers. The Compliance Committee’s responsibilities include, without limitation: (i) overseeing the compliance policies and procedures of the Fund and its service providers and recommending changes or additions to such policies and procedures; (ii) reviewing information on and, where appropriate, recommending policies concerning the Fund’s compliance with applicable law; (iii) reviewing information on any significant correspondence with or other actions by regulators or governmental agencies with respect to the Fund and any employee complaints or published reports that raise concerns regarding compliance matters; and (iv) reviewing reports from, overseeing the annual performance review of, and making certain recommendations in respect of, the CCO, including, without limitation, determining the amount and structure of the CCO’s compensation. The Board has adopted a written charter for the Board’s Compliance Committee. During the fiscal year ended April 30, 2019, the Compliance Committee met 4 times.

Performance Oversight Committee. The Board has a Performance Oversight Committee composed of Frank J. Fabozzi (Chair), Michael J. Castellano, Richard E. Cavanagh, Cynthia L. Egan, R. Glenn Hubbard, W. Carl Kester, Catherine A. Lynch and Karen P. Robards, all of whom are Independent Directors. The Performance Oversight Committee’s purpose is to assist the Board in fulfilling its responsibility to oversee the Fund’s investment performance relative to the Fund’s investment objective, policies and practices. The Performance Oversight Committee’s responsibilities include, without limitation: (i) reviewing the Fund’s investment objective, policies and practices; (ii) recommending to the Board any required action in respect of

changes in fundamental and non-fundamental investment restrictions; (iii) reviewing information on appropriate benchmarks and competitive universes; (iv) reviewing the Fund’s investment performance relative to such benchmarks; (v) reviewing information on unusual or exceptional investment matters; (vi) reviewing whether the Fund has complied with its investment policies and restrictions; and (vii) overseeing policies, procedures and controls regarding valuation of the Fund’s investments. The Board has adopted a written charter for the Board’s Performance Oversight Committee. During the fiscal year ended April 30, 2019, the Performance Oversight Committee met 4 times.

Executive Committee. The Board has an Executive Committee composed of Richard E. Cavanagh (Chair), and Karen P. Robards, both of whom are Independent Directors, and John M. Perlowski, who serves as an interested Director. The principal responsibilities of the Executive Committee include, without limitation: (i) acting on routine matters between meetings of the Board; (ii) acting on such matters as may require urgent action between meetings of the Board; and (iii) exercising such other authority as may from time to time be delegated to the Executive Committee by the Board. The Board has adopted a written charter for the Board’s Executive Committee. During the fiscal year ended April 30, 2019, the Executive Committee did not meet.

Information about the specific experience, skills, attributes and qualifications of each Director, which in each case led to the Board’s conclusion that the Director should serve (or continue to serve) as a Director of the Fund, is provided in “Biographical Information of the Directors.”

Each Director who is an Independent Director is paid an annual retainer of $330,000 per year for his or her services as a Board member of the BlackRock-advised Funds, including the Fund, and each Independent Director may also receive a $10,000 Board meeting fee for special unscheduled meetings or meetings in excess of six Board meetings held in a calendar year, together with out-of-pocket expenses in accordance with a Board policy on travel and other business expenses relating to attendance at meetings. In addition, each Co-Chair of the Board is paid an additional annual retainer of $100,000. The Chairs of the Audit Committee, Performance Oversight Committee, Compliance Committee, and Governance and Nominating Committee are paid an additional annual retainer of $45,000, $30,000, $45,000 and $20,000, respectively. Each of the members of the Audit Committee

and Compliance Committee are paid an additional annual retainer of $30,000 and $25,000, respectively, for his or her service on such committee. The Fund will pay a pro rata portion quarterly (based on relative net assets) of the foregoing Director fees paid by the funds in the BlackRock Fixed-Income Complex.

The Independent Directors have agreed that a maximum of 50% of each Independent Director’s total compensation paid by funds in the BlackRock Fixed-Income Complex may be deferred pursuant to the BlackRock Fixed-Income Complex’s deferred compensation plan. Under the deferred compensation plan, deferred amounts earn a return for the Independent Directors as though equivalent dollar amounts had been invested in shares of certain funds in the BlackRock Fixed-Income Complex selected by the Independent Directors. This has approximately the same economic effect for the Independent Directors as if they had invested the deferred amounts in such funds in the BlackRock Fixed-Income Complex. The deferred compensation plan is not funded and obligations thereunder represent general unsecured claims against the general assets of a fund and are recorded as a liability for accounting purposes.

Prior to January 1, 2019, each Independent Director of the Fund was subject to a different compensation arrangement with respect to his or her services as a member of the board of directors/trustees of certain other BlackRock-advised Funds.

The following table sets forth the compensation paid to the Directors by the Fund for the fiscal year ended April 30, 2019, and the aggregate compensation paid to them by all BlackRock-advised Funds for the calendar year ended December 31, 2019. Messrs. Fairbairn and Perlowski serve without compensation from the Fund because of their affiliation with BlackRock, Inc. and the Advisor.

As of December 31, 2019, none of the Independent Directors of the Fund or their immediate family members owned beneficially or of record any securities of BlackRock or any affiliate of any BlackRock person controlling, controlled by or under common control with BlackRock nor did any Independent Director of the Fund or their immediate family member have any material interest in any transaction, or series of similar transactions, during the most recently completed two calendar years involving the Fund, BlackRock or any affiliate of any BlackRock person controlling, controlled by or under common control with the Fund or BlackRock.

As of the date of this SAI, the officers and Directors of the Fund, as a group, beneficially owned less than 1% of the outstanding common shares of the Fund.

Certain biographical and other information relating to the officers of the Fund who are not Directors is set forth below, including their address and year of birth, principal occupations for at least the last five years and length of time served. With the exception of the CCO, executive officers receive no compensation from the Fund. The Fund compensates the CCO for his services as its CCO.

Each executive officer is an “interested person” of the Fund (as defined in the Investment Company Act) by virtue of that individual’s position with BlackRock or its affiliates described in the table below.

The governing documents of the Fund generally provide that, to the extent permitted by applicable law, the Fund will indemnify its Directors and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Fund unless, as to liability to the Fund or its investors, it is finally adjudicated that they engaged in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in their offices. In addition, the Fund will not indemnify Directors with respect to any matter as to which Directors did not act in good faith in the reasonable belief that his or her action was in the best interest of the Fund or, in the case of any criminal proceeding, as to which Directors had reasonable cause to believe that the conduct was unlawful. Indemnification provisions contained in the Fund’s governing documents are subject to any limitations imposed by applicable law.

Closed-end funds in the BlackRock Fixed-Income Complex, including the Fund, have also entered into a separate indemnification agreement with the board members of each board of such funds (the “Indemnification Agreement”). The Indemnification Agreement (i) extends the indemnification provisions contained in a fund’s governing documents to board members who leave that fund’s board and serve on an advisory board of a different fund in the BlackRock Fixed-Income Complex; (ii) sets in place the terms of the indemnification provisions of a fund’s governing documents once a board member retires from a board; and (iii) in the case of board members who left the board of a fund in connection with or prior to the board consolidation that occurred in 2007 as a result of the merger of BlackRock and Merrill Lynch & Co., Inc.’s investment management business, clarifies that such fund continues to indemnify the trustee for claims arising out of his or her past service to that fund.

The discussion below describes the portfolio managers’ compensation as of April 30, 2019.

The Advisor’s financial arrangements with its portfolio managers, its competitive compensation and its career path emphasis at all levels reflect the value senior management places on key resources. Compensation may include a variety of components and may vary from year to year based on a number of factors. The principal components of compensation include a base salary, a performance-based discretionary bonus, participation in various benefits programs and one or more of the incentive compensation programs established by the Advisor.

Base Compensation. Generally, portfolio managers receive base compensation based on their position with the firm.

Discretionary incentive compensation is a function of several components: the performance of BlackRock, Inc., the performance of the portfolio manager’s group within BlackRock, the investment performance, including risk-adjusted returns, of the firm’s assets under management or supervision by that portfolio manager relative to predetermined benchmarks, and the individual’s performance and contribution to the overall performance of these portfolios and BlackRock. In most cases, these benchmarks are the same as the benchmark or benchmarks against which the performance of the Fund or other accounts managed by the portfolio managers are measured. Among other things, BlackRock’s Chief Investment Officers make a subjective determination with respect to each portfolio manager’s compensation based on the performance of the Fund and other accounts managed by each portfolio manager relative to the various benchmarks. Performance of fixed-income funds is measured on a pre-tax and/or after-tax basis over various time periods including 1-, 3- and 5- year periods, as applicable. With respect to these portfolio managers, such benchmarks for the Fund and other accounts are: a combination of market-based indices (e.g., Standard & Poor’s Municipal Bond Index), certain customized indices and certain fund industry peer groups.

Distribution of Discretionary Incentive Compensation. Discretionary incentive compensation is distributed to portfolio managers in a combination of cash, deferred BlackRock, Inc. stock awards, and/or deferred cash awards that notionally track the return of certain BlackRock investment products.

Portfolio managers receive their annual discretionary incentive compensation in the form of cash. Portfolio managers whose total compensation is above a specified threshold also receive deferred BlackRock, Inc. stock awards annually as part of their discretionary incentive compensation. Paying a portion of discretionary incentive compensation in the form of deferred BlackRock, Inc. stock puts compensation earned by a portfolio manager for a given year “at risk” based on BlackRock’s ability to sustain and improve its performance over future periods. In some cases, additional deferred BlackRock, Inc. stock may be granted to certain key employees as part of a long-term incentive award to aid in retention, align interests with long-term shareholders and motivate performance. Deferred BlackRock, Inc. stock awards are generally granted in the form of BlackRock, Inc. restricted stock units that vest pursuant to the terms of the applicable plan and, once vested, settle in BlackRock, Inc. common stock. The portfolio managers of this Fund have deferred BlackRock, Inc. stock awards.

For certain portfolio managers, a portion of the discretionary incentive compensation is also distributed in the form of deferred cash awards that notionally track the returns of select BlackRock investment products they manage, which provides direct alignment of portfolio manager discretionary incentive compensation with investment product results. Deferred cash awards vest ratably over a number of years and, once vested, settle in the form of cash. Only portfolio managers who manage specified products and whose total compensation is above a specified threshold are eligible to participate in the deferred cash award program.

Other Compensation Benefits. In addition to base salary and discretionary incentive compensation, portfolio managers may be eligible to receive or participate in one or more of the following:

Incentive Savings Plans—BlackRock, Inc. has created a variety of incentive savings plans in which BlackRock, Inc. employees are eligible to participate, including a 401(k) plan, the BlackRock Retirement Savings Plan (RSP), and the BlackRock Employee Stock Purchase Plan (ESPP). The employer contribution components of the RSP include a company match equal to 50% of the first 8% of eligible pay contributed to the plan capped at $5,000 per year, and a company retirement contribution equal to 3-5% of eligible compensation up to the Internal Revenue Service limit ($280,000 for 2019). The RSP offers a range of investment options, including registered investment companies and collective investment funds managed by the firm. BlackRock, Inc. contributions follow the investment direction set by participants for their own contributions or, absent participant investment direction, are invested into a target date fund that corresponds to, or is closest to, the year in which the participant attains age 65. The ESPP allows for investment in BlackRock, Inc. common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is

limited to the purchase of 1,000 shares of common stock or a dollar value of $25,000 based on its fair market value on the purchase date. All of the eligible portfolio managers are eligible to participate in these plans.

The Advisor has built a professional working environment, firm-wide compliance culture and compliance procedures and systems designed to protect against potential incentives that may favor one account over another. The Advisor has adopted policies and procedures that address the allocation of investment opportunities, execution of portfolio transactions, personal trading by employees and other potential conflicts of interest that are designed to ensure that all client accounts are treated equitably over time. Nevertheless, the Advisor furnishes investment management and advisory services to numerous clients in addition to the Fund, and the Advisor may, consistent with applicable law, make investment recommendations to other clients or accounts (including accounts which are hedge funds or have performance or higher fees paid to the Advisor, or in which portfolio managers have a personal interest in the receipt of such fees), which may be the same as or different from those made to the Fund. In addition, BlackRock, Inc., its affiliates and significant shareholders and any officer, director, shareholder or employee may or may not have an interest in the securities whose purchase and sale the Advisor recommends to the Fund. BlackRock, Inc., or any of its affiliates or significant shareholders, or any officer, director, shareholder, employee or any member of their families may take different actions than those recommended to the Fund by the Advisor with respect to the same securities. Moreover, the Advisor may refrain from rendering any advice or services concerning securities of companies of which any of BlackRock, Inc.’s (or its affiliates’ or significant shareholders’) officers, directors or employees are directors or officers, or companies as to which BlackRock, Inc. or any of its affiliates or significant shareholders or the officers, directors and employees of any of them has any substantial economic interest or possesses material non-public information. Certain portfolio managers also may manage accounts whose investment strategies may at times be opposed to the strategy utilized for a fund. It should also be noted that a portfolio manager may be managing certain hedge fund and/or long only accounts, or may be part of a team managing certain hedge fund and/or long only accounts, subject to incentive fees. Such portfolio managers may therefore be entitled to receive a portion of any incentive fees earned on such accounts. Currently, the portfolio managers of this fund are not entitled to receive a portion of incentive fees of other accounts.

As a fiduciary, the Advisor owes a duty of loyalty to its clients and must treat each client fairly. When the Advisor purchases or sells securities for more than one account, the trades must be allocated in a manner consistent with its fiduciary duties. The Advisor attempts to allocate investments in a fair and equitable manner among client accounts, with no account receiving preferential treatment. To this end, BlackRock, Inc. has adopted policies that are intended to ensure reasonable efficiency in client transactions and provide the Advisor with sufficient flexibility to allocate investments in a manner that is consistent with the particular investment discipline and client base, as appropriate.

The Board has delegated the voting of proxies for the Fund’s securities to the Advisor pursuant to the Advisor’s proxy voting guidelines. Under these guidelines, the Advisor will vote proxies related to Fund securities in the best interests of the Fund and its shareholders. From time to time, a vote may present a conflict

between the interests of the Fund’s shareholders, on the one hand, and those of the Advisor, or any affiliated person of the Fund or the Advisor, on the other. In such event, provided that the Advisor’s Equity Investment Policy Oversight Committee, or a sub-committee thereof (the “Oversight Committee”), is aware of the real or potential conflict, if the matter to be voted on represents a material, non-routine matter and if the Oversight Committee does not reasonably believe it is able to follow its general voting guidelines (or if the particular proxy matter is not addressed in the guidelines) and vote impartially, the Oversight Committee may retain an independent fiduciary to advise the Oversight Committee on how to vote or to cast votes on behalf of the Advisor’s clients. If the Advisor determines not to retain an independent fiduciary, or does not desire to follow the advice of such independent fiduciary, the Oversight Committee shall determine how to vote the proxy after consulting with the Advisor’s Portfolio Management Group and/or the Advisor’s Legal and Compliance Department and concluding that the vote cast is in its client’s best interest notwithstanding the conflict. A copy of the Closed-End Fund Proxy Voting Policy is included as Appendix B to this SAI. Information on how the Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 will be available (i) at www.blackrock.com and (ii) on the SEC’s website at http://www.sec.gov.

The Fund and the Advisor have adopted codes of ethics pursuant to Rule 17j-1 under the Investment Company Act. These codes permit personnel subject to the codes to invest in securities, including securities that may be purchased or held by the Fund. These codes may be obtained by calling the SEC at (202) 551-8090. These codes of ethics are available on the EDGAR Database on the SEC’s website (http://www.sec.gov), and copies of these codes may be obtained, after paying a duplicating fee, by electronic request at the following e-mail address: publicinfo@sec.gov.

BlackRock, Inc. is independent in ownership and governance, with no single majority stockholder and a majority of independent directors. PNC (as defined below) is BlackRock, Inc.’s largest stockholder.

Subject to policies established by the Board, the Advisor is primarily responsible for the execution of the Fund’s portfolio transactions and the allocation of brokerage. The Advisor does not execute transactions through any particular broker or dealer, but seeks to obtain the best net results for the Fund, taking into account such factors as price (including the applicable brokerage commission or dealer spread), size of order, difficulty of execution, operational facilities of the firm and the firm’s risk and skill in positioning blocks of securities. While the Advisor generally seeks reasonable trade execution costs, the Fund does not necessarily pay the lowest spread or commission available, and payment of the lowest commission or spread is not necessarily consistent with obtaining the best price and execution in particular transactions. Subject to applicable legal requirements, the Advisor may select a broker based partly upon brokerage or research services provided to the Advisor and its clients, including the Fund. In return for such services, the Advisor may cause the Fund to pay a higher commission than other brokers would charge if the Advisor determines in good faith that the commission is reasonable in relation to the services provided.

In selecting brokers or dealers to execute portfolio transactions, the Advisor seeks to obtain the best price and most favorable execution for the Fund, taking into account a variety of factors including: (i) the size, nature and character of the security or instrument being traded and the markets in which it is purchased or sold; (ii) the desired timing of the transaction; (iii) the Advisor’s knowledge of the expected commission rates and spreads currently available; (iv) the activity existing and expected in the market for the particular security or instrument, including any anticipated execution difficulties; (v) the full range of brokerage services provided; (vi) the broker’s or dealer’s capital; (vii) the quality of research and research services provided; (viii) the reasonableness of the commission, dealer spread or its equivalent for the specific transaction; and (ix) the Advisor’s knowledge of any actual or apparent operational problems of a broker or dealer.

Section 28(e) of the Exchange Act (“Section 28(e)”) permits an investment adviser, under certain circumstances, to cause an account to pay a broker or dealer a commission for effecting a transaction that exceeds the amount another broker or dealer would have charged for effecting the same transaction in recognition of the value of brokerage and research services provided by that broker or dealer. This includes commissions paid on riskless principal transactions under certain conditions. Brokerage and research services include: (1) furnishing advice as to the value of securities, including pricing and appraisal advice, credit analysis, risk measurement analysis, performance and other analysis, as well as the advisability of investing in, purchasing or selling securities, and the availability of securities or purchasers or sellers of securities; (2) furnishing analyses and reports concerning issuers, industries, securities, economic factors and trends, portfolio strategy, and the performance of accounts; and (3) effecting securities transactions and performing functions incidental to securities transactions (such as clearance, settlement, and custody). The Advisor believes that access to independent investment research is beneficial to its investment decision-making processes and, therefore, to the Fund.

The Advisor may participate in client commission arrangements under which the Advisor may execute transactions through a broker-dealer and request that the broker-dealer allocate a portion of the commissions or commission credits to another firm that provides research to the Advisor. The Advisor believes that research services obtained through soft dollar or commission sharing arrangements enhance its investment decision-making capabilities, thereby increasing the prospects for higher investment returns. The Advisor will engage only in soft dollar or commission sharing transactions that comply with the requirements of Section 28(e). The Advisor regularly evaluates the soft dollar products and services utilized, as well as the overall soft dollar and commission sharing arrangements to ensure that trades are executed by firms that are regarded as best able to execute trades for client accounts, while at the same time providing access to the research and other services the Advisor views as impactful to its trading results.

The Advisor may utilize soft dollars and related services, including research (whether prepared by the broker-dealer or prepared by a third-party and provided to the Advisor by the broker-dealer) and execution or brokerage services within applicable rules and the Advisor’s policies to the extent that such permitted services do not compromise the Advisor’s ability to seek to obtain best execution. In this regard, the portfolio management investment and/or trading teams may consider a variety of factors, including the degree to which the broker-dealer: (a) provides access to company management; (b) provides access to their analysts; (c) provides meaningful/insightful research notes on companies or other potential investments; (d) facilitates calls on which meaningful or insightful ideas about companies or potential investments are discussed; (e) facilitates conferences at which meaningful or insightful ideas about companies or potential investments are discussed; or (f) provides research tools such as market data, financial analysis, and other third party related research and brokerage tools that aid in the investment process.

Research-oriented services for which the Advisor might pay with Fund commissions may be in written form or through direct contact with individuals and may include information as to particular companies or industries and securities or groups of securities, as well as market, economic, or institutional advice and statistical information, political developments and technical market information that assists in the valuation of investments. Except as noted immediately below, research services furnished by brokers may be used in servicing some or all client accounts and not all services may be used in connection with the Fund or account that paid commissions to the broker providing such services. In some cases, research information received from brokers by investment company management personnel, or personnel principally responsible for the Advisor’s individually managed portfolios, is not necessarily shared by and between such personnel. Any investment advisory or other fees paid by the Fund to the Advisor are not reduced as a result of the Advisor’s receipt of research services. In some cases, the Advisor may receive a service from a broker that has both a “research” and a “non-research” use. When this occurs the Advisor makes a good faith allocation, under all the circumstances, between the research and non-research uses of the service. The percentage of the service that is used for research purposes may be paid for with client commissions, while the Advisor will use its own funds to pay for the percentage of the service that is used for non-research purposes. In making this good faith allocation, the Advisor faces a potential conflict of

interest, but the Advisor believes that its allocation procedures are reasonably designed to ensure that it appropriately allocates the anticipated use of such services to their research and non-research uses.

Payments of commissions to brokers who are affiliated persons of the Fund will be made in accordance with Rule 17e-1 under the Investment Company Act.

From time to time, the Fund may purchase new issues of securities in a fixed price offering. In these situations, the broker may be a member of the selling group that will, in addition to selling securities, provide the Advisor with research services. The Financial Industry Regulatory Authority, Inc. has adopted rules expressly permitting these types of arrangements under certain circumstances. Generally, the broker will provide research “credits” in these situations at a rate that is higher than that available for typical secondary market transactions. These arrangements may not fall within the safe harbor of Section 28(e).

The Advisor does not consider sales of shares of the investment companies it advises as a factor in the selection of brokers or dealers to execute portfolio transactions for the Fund; however, whether or not a particular broker or dealer sells shares of the investment companies advised by the Advisor neither qualifies nor disqualifies such broker or dealer to execute transactions for those investment companies.

The Fund anticipates that its brokerage transactions involving foreign securities generally will be conducted primarily on the principal stock exchanges of the applicable country. Foreign equity securities may be held by the Fund in the form of depositary receipts, or other securities convertible into foreign equity securities. Depositary receipts may be listed on stock exchanges, or traded in OTC markets in the United States or Europe, as the case may be. American Depositary Receipts, like other securities traded in the United States, will be subject to negotiated commission rates.

The Fund may invest in certain securities traded in the OTC market and intends to deal directly with the dealers who make a market in the particular securities, except in those circumstances in which better prices and execution are available elsewhere. Under the Investment Company Act, persons affiliated with the Fund and persons who are affiliated with such affiliated persons are prohibited from dealing with the Fund as principal in the purchase and sale of securities unless a permissive order allowing such transactions is obtained from the SEC. Since transactions in the OTC market usually involve transactions with the dealers acting as principal for their own accounts, the Fund will not deal with affiliated persons in connection with such transactions. However, an affiliated person of the Fund may serve as its broker in OTC transactions conducted on an agency basis provided that, among other things, the fee or commission received by such affiliated broker is reasonable and fair compared to the fee or commission received by non-affiliated brokers in connection with comparable transactions.

OTC issues, including most fixed-income securities such as corporate debt and U.S. Government securities, are normally traded on a “net” basis without a stated commission, through dealers acting for their own account and not as brokers. The Fund will primarily engage in transactions with these dealers or deal directly with the issuer unless a better price or execution could be obtained by using a broker. Prices paid to a dealer with respect to both foreign and domestic securities will generally include a “spread,” which is the difference between the prices at which the dealer is willing to purchase and sell the specific security at the time, and includes the dealer’s normal profit.

Purchases of money market instruments by the Fund are made from dealers, underwriters and issuers. The Fund does not currently expect to incur any brokerage commission expense on such transactions because money market instruments are generally traded on a “net” basis with dealers acting as principal for their own accounts without a stated commission. The price of the security, however, usually includes a profit to the dealer.

Securities purchased in underwritten offerings include a fixed amount of compensation to the underwriter, generally referred to as the underwriter’s concession or discount. When securities are purchased or sold directly from or to an issuer, no commissions or discounts are paid.

The Advisor may seek to obtain an undertaking from issuers of commercial paper or dealers selling commercial paper to consider the repurchase of such securities from the Fund prior to maturity at their original cost plus interest (sometimes adjusted to reflect the actual maturity of the securities), if it believes that the Fund’s anticipated need for liquidity makes such action desirable. Any such repurchase prior to maturity reduces the possibility that the Fund would incur a capital loss in liquidating commercial paper, especially if interest rates have risen since acquisition of such commercial paper.

Investment decisions for the Fund and for other investment accounts managed by the Advisor are made independently of each other in light of differing conditions. The Advisor allocates investments among client accounts in a fair and equitable manner. A variety of factors will be considered in making such allocations. These factors include: (i) investment objectives or strategies for particular accounts, including sector, industry, country or region and capitalization weightings, (ii) tax considerations of an account, (iii) risk or investment concentration parameters for an account, (iv) supply or demand for a security at a given price level, (v) size of available investment, (vi) cash availability and liquidity requirements for accounts, (vii) regulatory restrictions, (viii) minimum investment size of an account, (ix) relative size of account, and (x) such other factors as may be approved by the Advisor’s general counsel. Moreover, investments may not be allocated to one client account over another based on any of the following considerations: (i) to favor one client account at the expense of another, (ii) to generate higher fees paid by one client account over another or to produce greater performance compensation to the Advisor, (iii) to develop or enhance a relationship with a client or prospective client, (iv) to compensate a client for past services or benefits rendered to the Advisor or to induce future services or benefits to be rendered to the Advisor, or (v) to manage or equalize investment performance among different client accounts.

Equity securities will generally be allocated among client accounts within the same investment mandate on a pro rata basis. This pro-rata allocation may result in the Fund receiving less of a particular security than if pro-ration had not occurred. All allocations of equity securities will be subject, where relevant, to share minimums established for accounts and compliance constraints.

Initial public offerings of securities may be over-subscribed and subsequently trade at a premium in the secondary market. When the Advisor is given an opportunity to invest in such an initial offering or “new” or “hot” issue, the supply of securities available for client accounts is often less than the amount of securities the accounts would otherwise take. In order to allocate these investments fairly and equitably among client accounts over time, each portfolio manager or a member of his or her respective investment team will indicate to the Advisor’s trading desk their level of interest in a particular offering with respect to eligible clients’ accounts for which that team is responsible. Initial public offerings of U.S. equity securities will be identified as eligible for particular client accounts that are managed by portfolio teams who have indicated interest in the offering based on market capitalization of the issuer of the security and the investment mandate of the client account and in the case of international equity securities, the country where the offering is taking place and the investment mandate of the client account. Generally, shares received during the initial public offering will be allocated among participating client accounts within each investment mandate on a pro rata basis. In situations where supply is too limited to be allocated among all accounts for which the investment is eligible, portfolio managers may rotate such investment opportunities among one or more accounts so long as the rotation system provides for fair access for all client accounts over time. Other allocation methodologies that are considered by the Advisor to be fair and equitable to clients may be used as well.

Because different accounts may have differing investment objectives and policies, the Advisor may buy and sell the same securities at the same time for different clients based on the particular investment objective, guidelines and strategies of those accounts. For example, the Advisor may decide that it may be entirely appropriate for a growth fund to sell a security at the same time a value fund is buying that security. To the extent that transactions on behalf of more than one client of the Advisor or its affiliates during the same period may increase the demand for securities being purchased or the supply of securities being sold, there may be an adverse effect on price. For example, sales of a security by the Advisor on behalf of one or more of its clients

may decrease the market price of such security, adversely impacting other of the Advisor’s clients that still hold the security. If purchases or sales of securities arise for consideration at or about the same time that would involve the Fund or other clients or funds for which the Advisor or an affiliate act as investment manager, transactions in such securities will be made, insofar as feasible, for the respective funds and clients in a manner deemed equitable to all.

In certain instances, the Advisor may find it efficient for purposes of seeking to obtain best execution, to aggregate or “bunch” certain contemporaneous purchases or sale orders of its advisory accounts. In general, all contemporaneous trades for client accounts under management by the same portfolio manager or investment team will be bunched in a single order if the trader believes the bunched trade would provide each client with an opportunity to achieve a more favorable execution at a potentially lower execution cost. The costs associated with a bunched order will be shared pro rata among the clients in the bunched order. Generally, if an order for a particular portfolio manager or management team is filled at several different prices through multiple trades, all accounts participating in the order will receive the average price except in the case of certain international markets where average pricing is not permitted. While in some cases this practice could have a detrimental effect upon the price or value of the security as far as the Fund is concerned, in other cases it could be beneficial to the Fund. Transactions effected by the Advisor on behalf of more than one of its clients during the same period may increase the demand for securities being purchased or the supply of securities being sold, causing an adverse effect on price. The trader will give the bunched order to the broker dealer that the trader has identified as being able to provide the best execution of the order. Orders for purchase or sale of securities will be placed within a reasonable amount of time of the order receipt and bunched orders will be kept bunched only long enough to execute the order.

The Fund will not purchase securities during the existence of any underwriting or selling group relating to such securities of which the Advisor or any affiliated person (as defined in the Investment Company Act) thereof is a member except pursuant to procedures adopted by the Board in accordance with Rule 10f-3 under the Investment Company Act. In no instance will portfolio securities be purchased from or sold to the Advisor or any affiliated person of the foregoing entities except as permitted by SEC exemptive order or by applicable law.

While the Fund generally does not expect to engage in trading for short-term gains, it will effect portfolio transactions without regard to any holding period if, in the Advisor’s judgment, such transactions are advisable in light of a change in circumstances of a particular company or within a particular industry or in general market, economic or financial conditions. The portfolio turnover rate is calculated by dividing the lesser of the Fund’s annual sales or purchases of portfolio securities (exclusive of purchases or sales of U.S. Government Securities and all other securities whose maturities at the time of acquisition were one year or less) by the monthly average value of the securities in the portfolio during the year. A high rate of portfolio turnover results in certain tax consequences, such as increased capital gain dividends and/or ordinary income dividends, and in correspondingly greater transaction costs in the form of dealer spreads and brokerage commissions, which are borne directly by the Fund.

Information about the brokerage commissions paid by the Fund, including commissions paid to affiliates, for the last three fiscal years, is set forth in the following table:

For the fiscal year ended April 30, 2019, the brokerage commissions paid to affiliates by the Fund represented [●]% of the aggregate brokerage commissions paid and involved [●]% of the dollar amount of transactions involving payment of commissions during the year.

The following table shows the dollar amount of brokerage commissions paid to brokers for providing third-party research services and the approximate dollar amount of the transactions involved for the fiscal year ended April 30, 2019. The provision of third-party research services was not necessarily a factor in the placement of all brokerage business with such brokers.

[As of April 30, 2019, the Fund held no securities of its “regular brokers or dealers” (as defined in Rule 10b-1 under the Investment Company Act) whose shares were purchased during the fiscal year ended April 30, 2019.]

The PNC Financial Services Group, Inc. (“PNC”), through a subsidiary, has a significant economic interest in BlackRock, Inc., the parent of the Advisor. Certain activities of BlackRock, Inc., the Advisor and the other subsidiaries of BlackRock, Inc. (collectively referred to in this section as “BlackRock”) and PNC and its subsidiaries (collectively referred to in this section as the “Entities”), and their respective directors, officers or employees, with respect to the Fund and/or other accounts managed by BlackRock or Entities, may give rise to actual or perceived conflicts of interest such as those described below.

BlackRock is one of the world’s largest asset management firms. PNC is a diversified financial services organization spanning the retail, business and corporate markets. BlackRock, PNC and their respective subsidiaries and each of their respective directors, officers and employees, including, in the case of BlackRock, the business units or entities and personnel who may be involved in the investment activities and business operations of the Fund, are engaged worldwide in businesses, including managing equities, fixed-income securities, cash and alternative investments, and banking and other financial services, and have interests other than that of managing the Fund. These are considerations of which investors in the Fund should be aware, and which may cause conflicts of interest that could disadvantage the Fund and its shareholders. These businesses and interests include potential multiple advisory, transactional, financial and other relationships with, or interests in companies and interests in securities or other instruments that may be purchased or sold by the Fund.

BlackRock and the Entities have proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of the Fund and/or that engage in transactions in the same types of securities, currencies and instruments as the Fund. BlackRock and the Entities are also major participants in the global currency, equities, swap and fixed-income markets, in each case, for the accounts of clients and, in some cases, on a proprietary basis. As such, BlackRock and the Entities are or may be actively engaged in transactions in the same securities, currencies, and instruments in which the Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which the Fund invests, which could have an adverse impact on the Fund’s performance. Such transactions, particularly in respect of most proprietary accounts or client accounts, will be executed independently of the Fund’s transactions and thus at prices or rates that may be more or less favorable than those obtained by the Fund.

When BlackRock seeks to purchase or sell the same assets for managed accounts, including the Fund, the assets actually purchased or sold may be allocated among the accounts on a basis determined in its good faith discretion to be equitable. In some cases, this system may adversely affect the size or price of the assets purchased or sold for the Fund. In addition, transactions in investments by one or more other accounts managed by BlackRock (or Entities) may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund, particularly, but not limited to, with respect to small capitalization, emerging

market or less liquid strategies. This may occur with respect to BlackRock-advised accounts when investment decisions regarding the Fund are based on research or other information that is also used to support decisions for other accounts. When BlackRock implements a portfolio decision or strategy on behalf of another account ahead of, or contemporaneously with, similar decisions or strategies for the Fund, market impact, liquidity constraints, or other factors could result in the Fund receiving less favorable trading results and the costs of implementing such decisions or strategies could be increased or the Fund could otherwise be disadvantaged. BlackRock may, in certain cases, elect to implement internal policies and procedures designed to limit such consequences, which may cause the Fund to be unable to engage in certain activities, including purchasing or disposing of securities, when it might otherwise be desirable for it to do so.

Conflicts may also arise because portfolio decisions regarding the Fund may benefit other accounts managed by BlackRock. For example, the sale of a long position or establishment of a short position by the Fund may impair the price of the same security sold short by (and therefore benefit) BlackRock or its other accounts or funds, and the purchase of a security or covering of a short position in a security by the Fund may increase the price of the same security held by (and therefore benefit) BlackRock or its other accounts or funds. In addition, to the extent permitted by applicable law, the Fund may invest its assets in other funds advised by BlackRock, including funds that are managed by one or more of the same portfolio managers, which could result in conflicts of interest relating to asset allocation, timing of Fund purchases and redemptions, and increased remuneration and profitability for BlackRock and/or its personnel, including portfolio managers.

In certain circumstances, BlackRock, on behalf of the Fund, may seek to buy from or sell securities to another fund or account advised by BlackRock. BlackRock may (but is not required to) effect purchases and sales between BlackRock clients (“cross trades”), including the Fund, if BlackRock believes such transactions are appropriate based on each party’s investment objectives and guidelines, subject to applicable law and regulation. There may be potential conflicts of interest or regulatory issues relating to these transactions which could limit BlackRock’s decision to engage in these transactions for the Fund. BlackRock may have a potentially conflicting division of loyalties and responsibilities to the parties in such transactions.

BlackRock and the Entities and their respective clients may pursue or enforce rights with respect to an issuer in which the Fund has invested, and those activities may have an adverse effect on the Fund. As a result, prices, availability, liquidity and terms of the Fund’s investments may be negatively impacted by the activities of BlackRock or the Entities or their respective clients, and transactions for the Fund may be impaired or effected at prices or terms that may be less favorable than would otherwise have been the case.

The results of the Fund’s investment activities may differ significantly from the results achieved by BlackRock for its proprietary accounts or other accounts (including investment companies or collective investment vehicles) which it manages or advises. It is possible that one or more accounts managed or advised by BlackRock and such other accounts will achieve investment results that are substantially more or less favorable than the results achieved by the Fund. Moreover, it is possible that the Fund will sustain losses during periods in which one or more proprietary or other accounts managed or advised by BlackRock achieve significant profits. The opposite result is also possible.

From time to time, the Fund may be restricted from purchasing or selling securities, or from engaging in other investment activities because of regulatory, legal or contractual requirements applicable to BlackRock or one or more Entities or other accounts managed or advised by BlackRock or an Entity for clients worldwide, and/or the internal policies of BlackRock and the Entities designed to comply with such requirements. As a result, there may be periods, for example, when BlackRock will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which BlackRock and/or one or more Entities are performing services or when position limits have been reached. For example, the investment activities of BlackRock for its proprietary accounts and accounts under its management may limit the investment opportunities for the Fund in certain emerging and other markets in which limitations are imposed upon the amount of investment, in the aggregate or in individual issuers, by affiliated foreign investors.

In connection with its management of the Fund, BlackRock may have access to certain fundamental analysis and proprietary technical models developed by BlackRock. BlackRock will not be under any obligation, however, to effect transactions on behalf of the Fund in accordance with such analysis and models. In addition, BlackRock will not have any obligation to make available any information regarding their proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for the benefit of the management of the Fund and it is not anticipated that BlackRock will have access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of BlackRock or the activities or strategies used for accounts managed by BlackRock or other client accounts could conflict with the transactions and strategies employed by BlackRock in managing the Fund.

In addition, certain principals and certain employees of the Fund’s investment adviser are also principals or employees of other business units or entities within BlackRock. As a result, these principals and employees may have obligations to such other business units or entities or their clients and such obligations to other business units or entities or their clients may be a consideration of which investors in the Fund should be aware.

BlackRock may enter into transactions and invest in securities, instruments and currencies on behalf of the Fund in which clients of BlackRock or an Entity, or, to the extent permitted by the SEC and applicable law, BlackRock or an Entity, serves as the counterparty, principal or issuer. In such cases, such party’s interests in the transaction will be adverse to the interests of the Fund, and such party may have no incentive to assure that the Fund obtains the best possible prices or terms in connection with the transactions. In addition, the purchase, holding and sale of such investments by the Fund may enhance the profitability of BlackRock or an Entity.

BlackRock or one or more Entities may also create, write or issue derivatives for their clients, the underlying securities, currencies or instruments of which may be those in which the Fund invests or which may be based on the performance of the Fund. BlackRock has entered into an arrangement with Markit Indices Limited, the index provider for underlying fixed-income indexes used by certain iShares ETFs, related to derivative fixed-income products that are based on such iShares ETFs. In connection with these products, BlackRock will receive certain payments for licensing intellectual property belonging to BlackRock and for facilitating provision of data in connection with such derivative products, which may include payments based on the trading volumes of, or revenues generated by, such products. The Fund and other accounts managed by BlackRock may transact in such products where permitted by the Fund’s investment strategy. These transactions could contribute to the viability of such products, potentially leading to increased payments to BlackRock, as well as greater liquidity for such products, increased purchase activity with respect to the applicable iShares ETFs and increased assets under management for BlackRock.

The Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by BlackRock or one or more Entities and may also enter into transactions with other clients of BlackRock or an Entity where such other clients have interests adverse to those of the Fund.

At times, these activities may cause business units or entities within BlackRock or an Entity to give advice to clients that may cause these clients to take actions adverse to the interests of the Fund. To the extent such transactions are permitted, the Fund will deal with BlackRock and/or Entities on an arms-length basis.

To the extent authorized by applicable law, BlackRock or one or more Entities may act as broker, dealer, agent, lender or adviser or in other commercial capacities for the Fund. It is anticipated that the commissions, mark-ups, mark-downs, financial advisory fees, underwriting and placement fees, sales fees, financing and commitment fees, brokerage fees, other fees, compensation or profits, rates, terms and conditions charged by BlackRock or an Entity will be in its view commercially reasonable, although BlackRock and each Entity, including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to BlackRock or the Entity and such sales personnel, which may have an adverse effect on the Fund.

Subject to applicable law, BlackRock and the Entities (and their personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Fund as broker,

dealer, agent, lender, adviser or in other commercial capacities. No accounting to the Fund or its shareholders will be required, and no fees or other compensation payable by the Fund or its shareholders will be reduced by reason of receipt by BlackRock or an Entity of any such fees or other amounts.

When BlackRock or an Entity acts as broker, dealer, agent, adviser or in other commercial capacities in relation to the Fund, BlackRock or the Entity may take commercial steps in its own interests, which may have an adverse effect on the Fund. The Fund will be required to establish business relationships with its counterparties based on the Fund’s own credit standing. BlackRock will not have any obligation to allow credit to be used in connection with the Fund’s establishment of its business relationships, nor is it expected that the Fund’s counterparties will rely on the credit of BlackRock in evaluating the Fund’s creditworthiness.

BlackRock Investment Management, LLC (“BIM”), an affiliate of BlackRock, pursuant to SEC exemptive relief, acts as securities lending agent to, and receives a share of securities lending revenues from, the Fund. BIM may receive compensation for managing the reinvestment of the cash collateral from securities lending. There are potential conflicts of interests in managing a securities lending program, including but not limited to: (i) BIM as securities lending agent may have an incentive to increase or decrease the amount of securities on loan or to lend particular securities in order to generate additional risk-adjusted revenue for BIM and its affiliates; and (ii) BIM as securities lending agent may have an incentive to allocate loans to clients that would provide more revenue to BIM. As described further below, BIM seeks to mitigate this conflict by providing its securities lending clients with equal lending opportunities over time in order to approximate pro-rata allocation.

As part of its securities lending program, BlackRock indemnifies certain clients and/or funds against a shortfall in collateral in the event of borrower default. BlackRock’s Risk and Quantitative Analytics Group (“RQA”) calculates, on a regular basis, BlackRock’s potential dollar exposure to the risk of collateral shortfall upon counterparty default (“shortfall risk”) under the securities lending program for both indemnified and non-indemnified clients. On a periodic basis, RQA also determines the maximum amount of potential indemnified shortfall risk arising from securities lending activities (“indemnification exposure limit”) and the maximum amount of counterparty-specific credit exposure (“credit limits”) BlackRock is willing to assume as well as the program’s operational complexity. RQA oversees the risk model that calculates projected shortfall values using loan-level factors such as loan and collateral type and market value as well as specific borrower counterparty credit characteristics. When necessary, RQA may further adjust other securities lending program attributes by restricting eligible collateral or reducing counterparty credit limits. As a result, the management of the indemnification exposure limit may affect the amount of securities lending activity BlackRock may conduct at any given point in time and impact indemnified and non-indemnified clients by reducing the volume of lending opportunities for certain loans (including by asset type, collateral type and/or revenue profile).

BlackRock uses a predetermined systematic process in order to approximate pro-rata allocation over time. In order to allocate a loan to a portfolio: (i) BlackRock as a whole must have sufficient lending capacity pursuant to the various program limits (i.e. indemnification exposure limit and counterparty credit limits); (ii) the lending portfolio must hold the asset at the time a loan opportunity arrives; and (iii) the lending portfolio must also have enough inventory, either on its own or when aggregated with other portfolios into one single market delivery, to satisfy the loan request. In doing so, BlackRock seeks to provide equal lending opportunities for all portfolios, independent of whether BlackRock indemnifies the portfolio. Equal opportunities for lending portfolios does not guarantee equal outcomes. Specifically, short and long-term outcomes for individual clients may vary due to asset mix, asset/liability spreads on different securities, and the overall limits imposed by the firm.

Purchases and sales of securities and other assets for the Fund may be bunched or aggregated with orders for other BlackRock client accounts, including with accounts that pay different transaction costs solely due to the fact that they have different research payment arrangements. BlackRock, however, is not required to bunch or aggregate orders if portfolio management decisions for different accounts are made separately, or if they determine that bunching or aggregating is not practicable or required, or in cases involving client direction.

Prevailing trading activity frequently may make impossible the receipt of the same price or execution on the entire volume of securities purchased or sold. When this occurs, the various prices may be averaged, and the Fund will be charged or credited with the average price. Thus, the effect of the aggregation may operate on some occasions to the disadvantage of the Fund. In addition, under certain circumstances, the Fund will not be charged the same commission or commission equivalent rates in connection with a bunched or aggregated order.

As discussed in the section entitled “Portfolio Transactions and Brokerage” in this SAI, BlackRock, unless prohibited by applicable law, may cause the Fund or account to pay a broker or dealer a commission for effecting a transaction that exceeds the amount another broker or dealer would have charged for effecting the same transaction in recognition of the value of brokerage and research services provided by that broker or dealer.

Subject to applicable law, BlackRock may select brokers (including, without limitation, certain Entities) that furnish BlackRock, the Fund, other BlackRock client accounts or personnel, directly or through correspondent relationships, with research or other appropriate services which provide, in BlackRock’s view, appropriate assistance to BlackRock in the investment decision-making process (including with respect to futures, fixed-price offerings and OTC transactions). Such research or other services may include, to the extent permitted by law, research reports on companies, industries and securities; economic and financial data; financial publications; proxy analysis; trade industry seminars; computer data bases; research-oriented software and other services and products.

Research or other services obtained in this manner may be used in servicing any or all of the Fund and other BlackRock client accounts, including in connection with BlackRock client accounts other than those that pay commissions to the broker relating to the research or other service arrangements. Such products and services may disproportionately benefit other BlackRock client accounts relative to the Fund based on the amount of brokerage commissions paid by the Fund and such other BlackRock client accounts. For example, research or other services that are paid for through one client’s commissions may not be used in managing that client’s account. In addition, other BlackRock client accounts may receive the benefit, including disproportionate benefits, of economies of scale or price discounts in connection with products and services that may be provided to the Fund and to such other BlackRock client accounts. To the extent that BlackRock uses soft dollars, it will not have to pay for those products and services itself.

BlackRock, unless prohibited by applicable law, may endeavor to execute trades through brokers who, pursuant to such arrangements, provide research or other services in order to ensure the continued receipt of research or other services BlackRock believes are useful in its investment decision-making process. BlackRock may from time to time choose not to engage in the above described arrangements to varying degrees. BlackRock, unless prohibited by applicable law, may also enter into commission sharing arrangements under which BlackRock may execute transactions through a broker-dealer, including, where permitted, an Entity, and request that the broker-dealer allocate a portion of the commissions or commission credits to another firm that provides research to BlackRock. To the extent that BlackRock engages in commission sharing arrangements, many of the same conflicts related to traditional soft dollars may exist.

BlackRock may utilize certain electronic crossing networks (“ECNs”) (including, without limitation, ECNs in which BlackRock or an Entity has an investment or other interest, to the extent permitted by applicable law) in executing client securities transactions for certain types of securities. These ECNs may charge fees for their services, including access fees and transaction fees. The transaction fees, which are similar to commissions or markups/markdowns, will generally be charged to clients and, like commissions and markups/markdowns, would generally be included in the cost of the securities purchased. Access fees may be paid by BlackRock even though incurred in connection with executing transactions on behalf of clients, including the Fund. In certain circumstances, ECNs may offer volume discounts that will reduce the access fees typically paid by BlackRock.

BlackRock will only utilize ECNs consistent with its obligation to seek to obtain best execution in client transactions.

BlackRock has adopted policies and procedures designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of advisory clients, including the Fund, and to help ensure that such decisions are made in accordance with BlackRock’s fiduciary obligations to its clients. Nevertheless, notwithstanding such proxy voting policies and procedures, actual proxy voting decisions of BlackRock may have the effect of favoring the interests of other clients or businesses of other divisions or units of BlackRock and/or an Entity, provided that BlackRock believes such voting decisions to be in accordance with its fiduciary obligations. For a more detailed discussion of these policies and procedures, see Appendix B.

It is possible that the Fund may invest in securities of, or engage in transactions with, companies with which an Entity has developed or is trying to develop investment banking relationships as well as securities of entities in which BlackRock or an Entity has significant debt or equity investments or other interests or in which an Entity makes a market. The Fund may also invest in issuances (such as structured notes) by entities for which BlackRock provides and is compensated for cash management services relating to the proceeds from the sale of such issuances. The Fund also may invest in securities of, or engage in transactions with, companies to which an Entity provides or may in the future provide research coverage. Such investments or transactions could cause conflicts between the interests of the Fund and the interests of BlackRock, other clients of BlackRock or an Entity. In making investment decisions for the Fund, BlackRock is not permitted to obtain or use material non-public information acquired by any unit of BlackRock, in the course of these activities. In addition, from time to time, the activities of BlackRock or an Entity may limit the Fund’s flexibility in purchases and sales of securities. When an Entity is engaged in an underwriting or other distribution of securities of an entity, BlackRock may be prohibited from purchasing or recommending the purchase of certain securities of that entity for the Fund. As indicated below, BlackRock or an Entity may engage in transactions with companies in which BlackRock-advised funds or other clients of BlackRock or of an Entity have an investment.

BlackRock and Chubb Limited (“Chubb”), a public company whose securities are held by BlackRock-advised funds and other accounts, partially funded the creation of a re-insurance company (“Re Co”) pursuant to which each has approximately a 9.9% ownership interest and each has representation on the board of directors. Certain employees and executives of BlackRock have a less than 1/2 of 1% ownership interest in Re Co.

BlackRock manages the investment portfolio of Re Co, which is held in a wholly-owned subsidiary. Re Co participates as a reinsurer with reinsurance contracts underwritten by subsidiaries of Chubb. An independent director of certain BlackRock-advised funds also serves as an independent director of Chubb and has no interest or involvement in the Re Co transaction.

BlackRock may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for such clients’ accounts may differ from the valuations for the same securities or investments assigned by the Fund’s pricing vendors, especially if such valuations are based on broker-dealer quotes or other data sources unavailable to the Fund’s pricing vendors. While BlackRock will generally communicate its valuation information or determinations to the Fund’s pricing vendors and/or fund accountants, there may be instances where the Fund’s pricing vendors or fund accountants assign a different valuation to a security or other investment than the valuation for such security or investment determined or recommended by BlackRock.

As disclosed in more detail in “Net Asset Value” in the prospectus, when market quotations are not readily available or are believed by BlackRock to be unreliable, the Fund’s investments are valued at fair value by BlackRock, in accordance with procedures adopted by the Fund’s Board of Directors. When determining a “fair value price,” BlackRock seeks to determine the price that the Fund might reasonably expect to receive from the current sale of that asset or liability in an arm’s-length transaction. The price generally may not be determined based on what the Fund might reasonably expect to receive for selling an asset or liability at a later time or if it holds the asset or liability to maturity. While fair value determinations will be based upon all available factors that BlackRock deems relevant at the time of the determination, and may be based on analytical values determined by BlackRock using proprietary or third party valuation models, fair value represents only a good

faith approximation of the value of an asset or liability. The fair value of one or more assets or liabilities may not, in retrospect, be the price at which those assets or liabilities could have been sold during the period in which the particular fair values were used in determining the Fund’s NAV. As a result, the Fund’s sale or repurchase of its shares at NAV, at a time when a holding or holdings are valued by BlackRock (pursuant to Board-adopted procedures) at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders and may affect the amount of revenue received by BlackRock with respect to services for which it receives an asset-based fee.

To the extent permitted by applicable law, the Fund may invest all or some of its short-term cash investments in any money market fund or similarly-managed private fund advised or managed by BlackRock. In connection with any such investments, the Fund, to the extent permitted by the Investment Company Act, may pay its share of expenses of a money market fund or other similarly-managed private fund in which it invests, which may result in the Fund bearing some additional expenses.

BlackRock and its directors, officers and employees, may buy and sell securities or other investments for their own accounts and may have conflicts of interest with respect to investments made on behalf of the Fund. As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers, and employees of BlackRock that are the same, different from or made at different times than positions taken for the Fund. To lessen the possibility that the Fund will be adversely affected by this personal trading, the Fund and the Advisor each have adopted a Code of Ethics in compliance with Section 17(j) of the Investment Company Act that restricts securities trading in the personal accounts of investment professionals and others who normally come into possession of information regarding the Fund’s portfolio transactions. Each Code of Ethics is also available on the EDGAR Database on the SEC’s Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mail at publicinfo@sec.gov.

BlackRock will not purchase securities or other property from, or sell securities or other property to, the Fund, except that the Fund may in accordance with rules or guidance adopted under the Investment Company Act engage in transactions with accounts that are affiliated with the Fund as a result of common officers, directors, or investment advisers or pursuant to exemptive orders granted to the Fund and/or BlackRock by the SEC. These transactions would be effected in circumstances in which BlackRock determined that it would be appropriate for the Fund to purchase and another client of BlackRock to sell, or the Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of the Fund may be restricted because of regulatory requirements applicable to BlackRock and/or BlackRock’s internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit their advice in certain securities or instruments issued by or related to companies for which BlackRock or an Entity is performing investment banking, market making, advisory or other services or has proprietary positions. For example, when BlackRock is engaged to provide advisory or risk management services for a company, BlackRock may be prohibited from or limited in purchasing or selling securities of that company on behalf of the Fund, particularly where such services result in BlackRock obtaining material non-public information about the company (e.g., in connection with participation in a creditors’ committee). Similar situations could arise if personnel of BlackRock serve as directors of companies the securities of which the Fund wishes to purchase or sell. However, if permitted by applicable law, and where consistent with BlackRock’s policies and procedures (including the necessary implementation of appropriate information barriers), the Fund may purchase securities or instruments that are issued by such companies, are the subject of an underwriting, distribution, or advisory assignment by an Entity or are the subject of an advisory or risk management assignment by BlackRock, or where personnel of BlackRock are directors or officers of the issuer.

The investment activities of BlackRock for their proprietary accounts and for client accounts may also limit the investment strategies and rights of the Fund. For example, in certain circumstances where the Fund invests in securities issued by companies that operate in certain regulated industries, in certain emerging or international

markets, or are subject to corporate or regulatory ownership restrictions, or invest in certain futures and derivative transactions, there may be limits on the aggregate amount invested by BlackRock for their proprietary accounts and for client accounts (including the Fund) that may not be exceeded without the grant of a license or other regulatory or corporate consent, or, if exceeded, may cause BlackRock, the Fund or other client accounts to suffer disadvantages or business restrictions. If certain aggregate ownership thresholds are reached or certain transactions undertaken, the ability of BlackRock on behalf of clients (including the Fund) to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. As a result, BlackRock on behalf of its clients (including the Fund) may limit purchases, sell existing investments, or otherwise restrict, forgo or limit the exercise of rights (including transferring, outsourcing or limiting voting rights or forgoing the right to receive dividends) when BlackRock, in its sole discretion, deems it appropriate in light of potential regulatory or other restrictions on ownership or other consequences resulting from reaching investment thresholds.

In those circumstances where ownership thresholds or limitations must be observed, BlackRock seeks to allocate limited investment opportunities equitably among clients (including the Fund), taking into consideration benchmark weight and investment strategy. When ownership in certain securities nears an applicable threshold, BlackRock may limit purchases in such securities to the issuer’s weighting in the applicable benchmark used by BlackRock to manage the Fund. If client (including Fund) holdings of an issuer exceed an applicable threshold and BlackRock is unable to obtain relief to enable the continued holding of such investments, it may be necessary to sell down these positions to meet the applicable limitations. In these cases, benchmark overweight positions will be sold prior to benchmark positions being reduced to meet applicable limitations.

In addition to the foregoing, other ownership thresholds may trigger reporting requirements to governmental and regulatory authorities, and such reports may entail the disclosure of the identity of a client or BlackRock’s intended strategy with respect to such security or asset.

BlackRock may maintain securities indices. To the extent permitted by applicable laws, the Fund may seek to license and use such indices as part of their investment strategy. Index based funds that seek to track the performance of securities indices also may use the name of the index or index provider in the fund name. Index providers, including BlackRock (to the extent permitted by applicable law), may be paid licensing fees for use of their index or index name. BlackRock is not obligated to license its indices to the Fund and the Fund is under no obligation to use BlackRock indices. The Fund cannot be assured that the terms of any index licensing agreement with BlackRock will be as favorable as those terms offered to other licensees.

BlackRock may enter into contractual arrangements with third-party service providers to the Fund (e.g., custodians, administrators and index providers) pursuant to which BlackRock receives fee discounts or concessions in recognition of BlackRock’s overall relationship with such service providers. To the extent that BlackRock is responsible for paying these service providers out of its management fee, the benefits of any such fee discounts or concessions may accrue, in whole or in part, to BlackRock.

BlackRock owns or has an ownership interest in certain trading, portfolio management, operations and/or information systems used by Fund service providers. These systems are, or will be, used by the Fund service provider in connection with the provision of services to accounts managed by BlackRock and funds managed and sponsored by BlackRock, including the Fund, that engage the service provider (typically the custodian). The Fund’s service provider remunerates BlackRock for the use of the systems. The Fund’s service provider’s payments to BlackRock for the use of these systems may enhance the profitability of BlackRock.

BlackRock’s receipt of fees from a service provider in connection with the use of systems provided by BlackRock may create an incentive for BlackRock to recommend that the Fund enter into or renew an arrangement with the service provider.

The Fund from time to time may purchase in the secondary market (i) certain mortgage pass-through securities packaged and master serviced by PNC Mortgage Securities Corp. (“PNC Mortgage”) or Midland Loan Services, Inc. (“Midland”), or (ii) mortgage-related securities containing loans or mortgages originated by PNC Bank, National Association (“PNC Bank”) or its affiliates. It is possible that under some circumstances, PNC Mortgage, Midland or other affiliates could have interests that are in conflict with the holders of these mortgage-backed securities, and such holders could have rights against PNC Mortgage, Midland or their affiliates. For example, if PNC Mortgage, Midland or their affiliates engaged in negligence or willful misconduct in carrying out its duties as a master servicer, then any holder of the mortgage-backed security could seek recourse against PNC Mortgage, Midland or their affiliates, as applicable. Also, as a master servicer, PNC Mortgage, Midland or their affiliates may make certain representations and warranties regarding the quality of the mortgages and properties underlying a mortgage-backed security. If one or more of those representations or warranties is false, then the holders of the mortgage-backed securities could trigger an obligation of PNC Mortgage, Midland or their affiliates, as applicable, to repurchase the mortgages from the issuing trust. Finally, PNC Mortgage, Midland or their affiliates may own securities that are subordinate to the senior mortgage-backed securities owned by the Fund.

Present and future activities of BlackRock (including BlackRock Advisors, LLC) and the Entities, and their respective directors, officers and employees, in addition to those described in this section, may give rise to additional conflicts of interest.

The Fund intends to hold annual meetings of shareholders so long as the common shares are listed on a national securities exchange and such meetings are required as a condition to such listing.

The Fund currently does not intend to issue preferred stock. Although the terms of any preferred stock that the Fund might issue in the future, including dividend rate, liquidation preference and redemption provisions, will be determined by the Board, subject to applicable law and the Charter, it is likely that any such preferred stock issued would be structured to carry a relatively short-term dividend rate reflecting interest rates on short-term debt securities, by providing for the periodic redetermination of the dividend rate at relatively short intervals through a fixed spread or remarketing procedure, subject to a maximum rate which would increase over time in the event of an extended period of unsuccessful remarketing. The Fund also believes that it is likely that the liquidation preference, voting rights and redemption provisions of any such preferred stock would be similar to those stated below.

Liquidation Preference. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Fund, the holders of shares of any outstanding preferred stock will be entitled to receive a preferential liquidating distribution (expected to equal the original purchase price per share plus an amount equal to accumulated but unpaid dividends, whether or not earned or declared) before any distribution of assets is made to holders of common stock. After payment of the full amount of the liquidating distribution to which they are entitled, it is expected that preferred stockholders will not be entitled to any further participation in any distribution of assets by the Fund. A consolidation or merger of the Fund with or into any other corporation or corporations or a sale of all or substantially all of the assets of the Fund will not be deemed to be a liquidation, dissolution or winding up of the Fund.

Voting Rights. Except as otherwise indicated in this prospectus and except as otherwise required by applicable law, holders of shares of any outstanding preferred stock will have equal voting rights with holders of

shares of common stock (one vote per share) and will vote together with holders of common stock as a single class. In connection with the election of the Fund’s Directors, holders of shares of any outstanding preferred stock, voting as a separate class, will be entitled to elect two of the Fund’s Directors, and the remaining Directors will be elected by all holders of capital stock, voting as a single class. So long as any preferred stock is outstanding, it is expected that the Fund will have not less than five Directors. If at any time dividends on shares of any outstanding preferred stock shall be unpaid in an amount equal to two full years’ dividends thereon, the holders of all outstanding shares of preferred stock, voting as a separate class, will be entitled to elect a majority of the Fund’s Directors until all dividends in default have been paid or declared and set apart for payment. It is expected that the affirmative vote of the holders of a majority of the outstanding shares of any outstanding preferred stock, voting as a separate class, will be required to (i) authorize, create or issue any class or series of stock ranking prior to any series of preferred stock with respect to payment of dividends or the distribution of assets on liquidation or (ii) amend, alter or repeal the provisions of the Charter, whether by merger, consolidation or otherwise, so as to adversely affect any of the contract rights expressly set forth in the Charter of holders of preferred stock.

Redemption Provisions. It is anticipated that any outstanding shares of preferred stock will generally be redeemable at the option of the Fund at a price equal to their liquidation preference plus accumulated but unpaid dividends to the date of redemption plus, under certain circumstances, a redemption premium. Shares of preferred stock will also be subject to mandatory redemption at a price equal to their liquidation preference plus accumulated but unpaid dividends to the date of redemption upon the occurrence of certain specified events, such as the failure of the Fund to maintain asset coverage requirements for the preferred stock specified by the 1940 Act and rating services that issue ratings on the preferred stock.]

Liquidity Feature. Preferred stock may include a liquidity feature that allows holders of preferred stock to have their shares purchased by a liquidity provider in the event that sell orders have not been matched with purchase orders and successfully settled in a remarketing. The Fund would pay a fee to the provider of this liquidity feature, which would be borne by common shareholders of the Fund. The terms of such liquidity feature may require the Fund to redeem preferred stock still owned by the liquidity provider following a certain period of continuous, unsuccessful remarketing, which may adversely impact the Fund.

The discussion above describes the possible offering of preferred stock by the Fund. If the Board determines to proceed with such an offering, the terms of the preferred stock may be the same as, or different from, the terms described above, subject to applicable law and the Charter. The Board, without the approval of the holders of common shares, may authorize an offering of preferred stock or may determine not to authorize such an offering, and may fix the terms of the preferred stock to be offered.

The Board (subject to applicable law and the Charter) may authorize an offering, without the approval of the holders of common shares and, depending on their terms, any preferred stock outstanding at that time, of other classes of shares, or other classes or series of shares, as they determine to be necessary, desirable or appropriate, having such terms, rights, preferences, privileges, limitations and restrictions as the Board sees fit. The Fund currently does not expect to issue any other classes of shares, or series of shares, except for the common shares.]

The Fund is a closed-end management investment company and as such its shareholders will not have the right to cause the Fund to redeem their shares. Instead, the Fund’s common shares will trade in the open market at a price that will be a function of several factors, including dividend levels (which are in turn affected by expenses), NAV, call protection for portfolio securities, dividend stability, liquidity, relative demand for and supply of the common shares in the market, general market and economic conditions and other factors. Because

shares of a closed-end investment company may frequently trade at prices lower than NAV, the Board may consider action that might be taken to reduce or eliminate any material discount from NAV in respect of common shares, which may include the repurchase of such shares in the open market or in private transactions, the making of a tender offer for such shares, or the conversion of the Fund to an open-end investment company. The Board may decide not to take any of these actions. In addition, there can be no assurance that share repurchases or tender offers, if undertaken, will reduce market discount.

Notwithstanding the foregoing, at any time when the Fund has preferred shares outstanding, the Fund may not purchase, redeem or otherwise acquire any of its common shares unless (1) all accrued preferred share dividends have been paid and (2) at the time of such purchase, redemption or acquisition, the NAV of the Fund’s portfolio (determined after deducting the acquisition price of the common shares) is at least 200% of the liquidation value of any outstanding preferred shares (expected to equal the original purchase price per share plus any accrued and unpaid dividends thereon). Any service fees incurred in connection with any tender offer made by the Fund will be borne by the Fund and will not reduce the stated consideration to be paid to tendering shareholders.

Subject to its investment restrictions, the Fund may borrow to finance the repurchase of shares or to make a tender offer. Interest on any borrowings to finance share repurchase transactions or the accumulation of cash by the Fund in anticipation of share repurchases or tender offers will reduce the Fund’s net income. Any share repurchase, tender offer or borrowing that might be approved by the Board would have to comply with the Exchange Act, the Investment Company Act and the rules and regulations thereunder.

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

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

In addition, a purchase by the Fund of its common shares will decrease the Fund’s net assets which would likely have the effect of increasing the Fund’s expense ratio. Any purchase by the Fund of its common shares at a time when preferred shares are outstanding will increase the leverage applicable to the outstanding common shares then remaining.

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

[The following is a description of certain U.S. federal income tax consequences to a shareholder of acquiring, holding and disposing of common shares of the Fund. Except as otherwise noted, this discussion assumes you are a taxable U.S. holder (as defined below). This discussion is based upon current provisions of the Internal Revenue Code of 1986, as amended (the “Code”), the regulations promulgated thereunder and judicial and administrative authorities, all of which are subject to change or differing interpretations by the courts or the Internal Revenue Service, possibly with retroactive effect. No attempt is made to present a detailed explanation of all U.S. federal income tax concerns affecting the Fund and its shareholders, and the discussions set forth here do not constitute tax advice. This discussion assumes that investors hold common shares of the Fund as capital assets (generally, for investment). The Fund has not sought and will not seek any ruling from the Internal Revenue Service regarding any matters discussed herein. No assurance can be given that the Internal Revenue Service would not assert, or that a court would not sustain, a position contrary to those set forth below. This summary does not discuss any aspects of foreign, state or local tax. Prospective investors must consult their own tax advisers as to the U.S. federal income tax consequences (including the alternative minimum tax consequences) of acquiring, holding and disposing of the Fund’s common shares, as well as the effects of state, local and non-U.S. tax laws.

A U.S. holder is a beneficial owner that is for U.S. federal income tax purposes:

The Fund intends to elect to be treated and to qualify to be taxed as a RIC under Subchapter M of the Code. In order to qualify as a RIC, the Fund must, among other things, satisfy certain requirements relating to the sources of its income, diversification of its assets, and distribution of its income to its shareholders. First, the Fund must derive

at least 90% of its annual gross income from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock or securities or foreign currencies, or other income (including but not limited to gains from options, futures and forward contracts) derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in “qualified publicly traded partnerships” (as defined in the Code) (the “90% gross income test”). Second, the Fund must diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the value of its total assets consists of cash, cash items, U.S. Government securities, securities of other RICs and other securities, with such other securities limited in respect of any one issuer to an amount not greater in value than 5% of the value of the Fund’s total assets and to not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of the total assets is invested in the securities (other than U.S. Government securities and securities of other RICs) of any one issuer, any two or more issuers controlled by the Fund and engaged in the same, similar or related trades or businesses, or any one or more “qualified publicly traded partnerships.”

The remainder of this discussion assumes that the Fund qualifies for taxation as a RIC.

Certain of the Fund’s investment practices are subject to special and complex U.S. federal income tax provisions (including mark-to-market, constructive sale, straddle, wash sale, short sale and other rules) that may, among other things, (i) disallow, suspend or otherwise limit the allowance of certain losses or deductions, (ii) convert lower taxed long-term capital gains or qualified dividend income into higher taxed short-term capital gains or ordinary income, (iii) convert ordinary loss or a deduction into capital loss (the deductibility of which is more limited), (iv) cause the Fund to recognize income or gain without a corresponding receipt of cash, (v) adversely affect the time as to when a purchase or sale of stock or securities is deemed to occur, (vi) adversely alter the characterization of certain complex financial transactions and (vii) produce income that will not be “qualified” income for purposes of the 90% annual gross income requirement described above. These U.S. federal income tax provisions could therefore affect the amount, timing and character of distributions to common shareholders. The Fund intends to monitor its transactions and may make certain tax elections and may be required to dispose of securities to mitigate the effect of these provisions and prevent disqualification of the Fund as a RIC. Additionally, the Fund may be required to limit its activities in derivative instruments in order to enable it to maintain its RIC status.

The Fund may invest a portion of its net assets in below investment grade securities, commonly known as “junk” securities. Investments in these types of securities may present special tax issues for the Fund. U.S. federal income tax rules are not entirely clear about issues such as when the Fund may cease to accrue interest, original issue discount or market discount, when and to what extent deductions may be taken for bad debts or worthless securities, how payments received on obligations in default should be allocated between principal and income and whether modifications or exchanges of debt obligations in a bankruptcy or workout context are taxable. These and other issues could affect the Fund’s ability to distribute sufficient income to preserve its status as a RIC or to avoid the imposition of U.S. federal income or excise tax.

Because the Fund may invest in foreign securities, its income from such securities may be subject to non-U.S. taxes. If more than 50% of the Fund’s total assets at the close of its taxable year consists of stock or securities of foreign corporations, the Fund may elect for U.S. federal income tax purposes to treat foreign income taxes paid by it as paid by its shareholders. The Fund may qualify for and make this election in some, but not necessarily all, of its taxable years. If the Fund were to make such an election, shareholders would be required to take into account an amount equal to their pro rata portions of such foreign taxes in computing their taxable income and then treat an amount equal to those foreign taxes as a U.S. federal income tax deduction or as a foreign tax credit against their U.S. federal income tax liability. A taxpayer’s ability to use a foreign tax deduction or credit is subject to limitations under the Code. Shortly after any year for which it makes such an election, the Fund will report to its shareholder the amount per share of such foreign income tax that must be included in each shareholder’s gross income and the amount that may be available for the deduction or credit.

Income from options on individual securities written by the Fund will generally not be recognized by the Fund for tax purposes until an option is exercised, lapses or is subject to a “closing transaction” (as defined by applicable regulations) pursuant to which the Fund’s obligations with respect to the option are otherwise terminated. If the option lapses without exercise, the premiums received by the Fund from the writing of such options will generally be characterized as short-term capital gain. If the Fund enters into a closing transaction, the difference between the premiums received and the amount paid by the Fund to close out its position will generally be treated as short-term capital gain or loss. If an option written by the Fund is exercised, thereby requiring the Fund to sell the underlying security, the premium will increase the amount realized upon the sale of the security, and the character of any gain on such sale of the underlying security as short-term or long-term capital gain will depend on the holding period of the Fund in the underlying security. Because the Fund will not have control over the exercise of the options it writes, such exercises or other required sales of the underlying securities may cause the Fund to realize gains or losses at inopportune times.

Options on indices of securities and sectors of securities that qualify as “section 1256 contracts” will generally be “marked-to-market” for U.S. federal income tax purposes. As a result, the Fund will generally recognize gain or loss on the last day of each taxable year equal to the difference between the value of the option on that date and the adjusted basis of the option. The adjusted basis of the option will consequently be increased by such gain or decreased by such loss. Any gain or loss with respect to options on indices and sectors that qualify as “section 1256 contracts” will be treated as short-term capital gain or loss to the extent of 40% of such gain or loss and long-term capital gain or loss to the extent of 60% of such gain or loss. Because the mark-to-market rules may cause the Fund to recognize gain in advance of the receipt of cash, the Fund may be required to dispose of investments in order to meet its distribution requirements. “Mark-to-market” losses may be suspended or otherwise limited if such losses are part of a straddle or similar transaction.

Distributions paid to you by the Fund from its net capital gain, if any, that the Fund properly reports as capital gain dividends (“capital gain dividends”) are taxable as long-term capital gains, regardless of how long you have held your common shares. All other dividends paid to you by the Fund (including dividends from net short-term capital gains or tax-exempt interest, if any) from its current or accumulated earnings and profits (“ordinary income dividends”) are generally subject to tax as ordinary income. Provided that certain holding period and other requirements are met, ordinary income dividends (if properly reported by the Fund) may qualify (i) for the dividends received deduction in the case of corporate shareholders to the extent that the Fund’s income consists of dividend income from U.S. corporations, and (ii) in the case of individual shareholders, as “qualified dividend income” eligible to be taxed at long-term capital gains rates to the extent that the Fund receives qualified dividend income. Qualified dividend income is, in general, dividend income from taxable domestic corporations and certain qualified foreign corporations (e.g., generally, foreign corporations incorporated in a possession of the United States or in certain countries with a qualifying comprehensive tax treaty with the United States, or whose stock with respect to which such dividend is paid is readily tradable on an established securities market in the United States). There can be no assurance as to what portion, if any, of the Fund’s distributions will constitute qualified dividend income or be eligible for the dividends received deduction.

The price of common shares purchased at any time may reflect the amount of a forthcoming distribution. Those purchasing common shares just prior to the record date for a distribution will receive a distribution which will be taxable to them even though it represents, economically, a return of invested capital.

The Fund will send you information after the end of each year setting forth the amount and tax status of any distributions paid to you by the Fund.

and ending 30 days after your sale or exchange of the common shares. In such case, your tax basis in the common shares acquired will be adjusted to reflect the disallowed loss.

If the Fund conducts a tender offer for its shares, a repurchase by the Fund of a shareholder’s shares pursuant to such tender offer generally will be treated as a sale or exchange of the shares by a shareholder provided that either (i) the shareholder tenders, and the Fund repurchases, all of such shareholder’s shares, thereby reducing the shareholder’s percentage ownership of the Fund, whether directly or by attribution under Section 318 of the Code, to 0%, (ii) the shareholder meets numerical safe harbors under the Code with respect to percentage voting interest and reduction in ownership of the Fund following completion of the tender offer, or (iii) the tender offer otherwise results in a “meaningful reduction” of the shareholder’s ownership percentage interest in the Fund, which determination depends on a particular shareholder’s facts and circumstances.

If a tendering shareholder’s proportionate ownership of the Fund (determined after applying the ownership attribution rules under Section 318 of the Code) is not reduced to the extent required under the tests described above, such shareholder will be deemed to receive a distribution from the Fund under Section 301 of the Code with respect to the shares held (or deemed held under Section 318 of the Code) by the shareholder after the tender offer (a “Section 301 distribution”). The amount of this distribution will equal the price paid by the Fund to such shareholder for the shares sold, and will be taxable as a dividend, i.e., as ordinary income, to the extent of the Fund’s current or accumulated earnings and profits allocable to such distribution, with the excess treated as a return of capital reducing the shareholder’s tax basis in the shares held after the tender offer, and thereafter as capital gain. Any Fund shares held by a shareholder after a tender offer will be subject to basis adjustments in accordance with the provisions of the Code.

Provided that no tendering shareholder is treated as receiving a Section 301 distribution as a result of selling shares pursuant to a particular tender offer, shareholders who do not sell shares pursuant to that tender offer will not realize constructive distributions on their shares as a result of other shareholders selling shares in the tender offer. In the event that any tendering shareholder is deemed to receive a Section 301 distribution, it is possible that shareholders whose proportionate ownership of the Fund increases as a result of that tender offer, including shareholders who do not tender any shares, will be deemed to receive a constructive distribution under Section 305(c) of the Code in an amount equal to the increase in their percentage ownership of the Fund as a result of the tender offer. Such constructive distribution will be treated as a dividend to the extent of current or accumulated earnings and profits allocable to it.

Use of the Fund’s cash to repurchase shares may adversely affect the Fund’s ability to satisfy the distribution requirements for treatment as a regulated investment company described above. The Fund may also recognize income in connection with the sale of portfolio securities to fund share purchases, in which case the Fund would take any such income into account in determining whether such distribution requirements have been satisfied.

If the Fund liquidates, shareholders generally will realize capital gain or loss upon such liquidation in an amount equal to the difference between the amount of cash or other property received by the shareholder (including any property deemed received by reason of its being placed in a liquidating trust) and the shareholder’s adjusted tax basis in its shares. Any such gain or loss will be long-term if the shareholder is treated as having a holding period in Fund shares of greater than one year, and otherwise will be short-term.

The foregoing discussion does not address the tax treatment of shareholders who do not hold their shares as a capital asset. Such shareholders should consult their own tax advisors on the specific tax consequences to them of participating or not participating in the tender offer or upon liquidation of the Fund.

Ordinary income dividends properly reported by the RIC are generally exempt from U.S. federal withholding tax where they (i) are paid in respect of the RIC’s “qualified net interest income” (generally, its U.S.-source interest income, other than certain contingent interest and interest from obligations of a corporation or partnership in which the RIC is at least a 10% shareholder, reduced by expenses that are allocable to such income) or (ii) are paid in respect of the RIC’s “qualified short-term capital gains” (generally, the excess of the RIC’s net short-term capital gain over its long-term capital loss for such taxable year). Depending on its circumstances, the Fund may report all, some or none of its potentially eligible dividends as such qualified net interest income or as qualified short-term capital gains, and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding. In order to qualify for this exemption from withholding, a foreign investor needs to comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing an IRS Form W-8BEN, W-8BEN-E, or substitute Form). In the case of common shares held through an intermediary, the intermediary may have withheld even if the Fund reported the payment as qualified net interest income or qualified short-term capital gain. Foreign investors should contact their intermediaries with respect to the application of these rules to their accounts. There can be no assurance as to what portion of the Fund’s distributions would qualify for favorable treatment as qualified net interest income or qualified short-term capital gains if the provision is extended.

In addition withholding at a rate of 30% will apply to dividends paid in respect of common shares of the Fund held by or through certain foreign financial institutions (including investment funds), unless such institution enters into an agreement with the Treasury to report, on an annual basis, information with respect to shares in, and accounts maintained by, the institution to the extent such shares or accounts are held by certain U.S. persons and by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments. Accordingly, the entity through which common shares of the Fund are held will affect the determination of whether such withholding is required. Similarly, dividends paid in respect of common shares of the Fund held by an investor that is a non-financial foreign entity that does not qualify under certain exemptions will be subject to withholding at a rate of 30%, unless such entity either (i) certifies that such entity does not have any “substantial United States owners” or (ii) provides certain information regarding the entity’s “substantial United States owners,” which the applicable withholding agent will in turn provide to the Secretary of the Treasury. An intergovernmental agreement between the United States and an applicable foreign country, or future Treasury regulations or other guidance, may modify these requirements. The Fund will not pay any additional amounts to common shareholders in respect of any amounts withheld. Foreign investors are encouraged to consult with their tax advisers regarding the possible implications of these rules on their investment in the Fund’s common shares.

the case of individuals, generally, their social security number) or to make required certifications, or who are otherwise subject to backup withholding. Backup withholding is not an additional tax and any amount withheld may be refunded or credited against your U.S. federal income tax liability, if any, provided that you timely furnish the required information to the Internal Revenue Service.

The foregoing is a general and abbreviated summary of certain provisions of the Code and the Treasury Regulations presently in effect as they directly govern the taxation of the Fund and its shareholders. For complete provisions, reference should be made to the pertinent Code sections and Treasury Regulations. The Code and the Treasury Regulations are subject to change by legislative or administrative action, and any such change may be retroactive with respect to Fund transactions. Holders of common shares are advised to consult their own tax advisers for more detailed information concerning the U.S. federal income taxation of the Fund and the income tax consequences to its holders of common shares.

S&P Global Ratings—A brief description of the applicable S&P Global Ratings (“S&P”) rating symbols and their meanings (as published by S&P) follows:

An S&P issue credit rating is a forward-looking opinion about the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations, or a specific financial program (including ratings on medium-term note programs and commercial paper programs). It takes into consideration the creditworthiness of guarantors, insurers, or other forms of credit enhancement on the obligation and takes into account the currency in which the obligation is denominated. The opinion reflects S&P’s view of the obligor’s capacity and willingness to meet its financial commitments as they come due, and this opinion may assess terms, such as collateral security and subordination, which could affect ultimate payment in the event of default.

Issue credit ratings can be either long-term or short-term. Short-term ratings are generally assigned to those obligations considered short-term in the relevant market. Short-term ratings are also used to indicate the creditworthiness of an obligor with respect to put features on long-term obligations. Medium-term notes are assigned long-term ratings.

Issue credit ratings are based, in varying degrees, on S&P’s analysis of the following considerations:

An issue rating is an assessment of default risk but may incorporate an assessment of relative seniority or ultimate recovery in the event of default. Junior obligations are typically rated lower than senior obligations, to reflect lower priority in bankruptcy, as noted above. (Such differentiation may apply when an entity has both senior and subordinated obligations, secured and unsecured obligations, or operating company and holding company obligations.)

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

An S&P U.S. municipal note rating reflects S&P’s opinion about the liquidity factors and market access risks unique to the notes. Notes due in three years or less will likely receive a note rating. Notes with an original maturity of more than three years will most likely receive a long-term debt rating. In determining which type of rating, if any, to assign, S&P’s analysis will review the following considerations:

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

Ratings assigned on Moody’s global long-term and short-term rating scales are forward-looking opinions of the relative credit risks of financial obligations issued by non-financial corporates, financial institutions, structured finance vehicles, project finance vehicles, and public sector entities. Long-term ratings are assigned to issuers or obligations with an original maturity of one year or more and reflect both on the likelihood of a default or impairment on contractual financial obligations and the expected financial loss suffered in the event of default or impairment. Short-term ratings are assigned to obligations with an original maturity of thirteen months or less and reflect both on the likelihood of a default or impairment on contractual financial obligations and the expected financial loss suffered in the event of default or impairment.

Note: Moody’s appends numerical modifiers 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category. Additionally, a “(hyb)” indicator is appended to all ratings of hybrid securities issued by banks, insurers, finance companies, and securities firms.*

* By their terms, hybrid securities allow for the omission of scheduled dividends, interest, or principal payments, which can potentially result in impairment if such an omission occurs. Hybrid securities may also be subject to contractually allowable write-downs of principal that could result in impairment. Together with the hybrid indicator, the long-term obligation rating assigned to a hybrid security is an expression of the relative credit risk associated with that security.

The Municipal Investment Grade (MIG) scale is used to rate US municipal bond anticipation notes of up to five years maturity. Municipal notes rated on the MIG scale may be secured by either pledged revenues or proceeds of a take-out financing received prior to note maturity. MIG ratings expire at the maturity of the obligation, and the issuer’s long-term rating is only one consideration in assigning the MIG rating. MIG ratings are divided into three levels—MIG 1 through MIG 3—while speculative grade short-term obligations are designated SG.

In the case of variable rate demand obligations (VRDOs), a two-component rating is assigned: a long or short-term debt rating and a demand obligation rating. The first element represents Moody’s evaluation of risk associated with scheduled principal and interest payments. The second element represents Moody’s evaluation of risk associated with the ability to receive purchase price upon demand (“demand feature”). The second element uses a rating from a variation of the MIG scale called the Variable Municipal Investment Grade (VMIG) scale.

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

Fitch’s credit ratings relating to issuers are an opinion on the relative ability of an entity to meet financial commitments, such as interest, preferred dividends, repayment of principal, insurance claims or counterparty obligations. Credit ratings are used by investors as indications of the likelihood of receiving the money owed to them in accordance with the terms on which they invested.

Fitch’s credit ratings do not directly address any risk other than credit risk. In particular, ratings do not deal with the risk of a market value loss on a rated security due to changes in interest rates, liquidity and other market considerations. However, in terms of payment obligation on the rated liability, market risk may be considered to the extent that it influences the ability of an issuer to pay upon a commitment. Ratings nonetheless do not reflect market risk to the extent that they influence the size or other conditionality of the obligation to pay upon a commitment (for example, in the case of index-linked bonds).

In the default components of ratings assigned to individual obligations or instruments, the agency typically rates to the likelihood of non-payment or default in accordance with the terms of that instrument’s documentation. In limited cases, Fitch may include additional considerations (i.e. rate to a higher or lower standard than that implied in the obligation’s documentation).

The terms “investment grade” and “speculative grade” have established themselves over time as shorthand to describe the categories ‘AAA’ to ‘BBB’ (investment grade) and ‘BB’ to ‘D’ (speculative grade). The terms investment grade and speculative grade are market conventions and do not imply any recommendation or endorsement of a specific security for investment purposes. Investment grade categories indicate relatively low to moderate credit risk, while ratings in the speculative categories either signal a higher level of credit risk or that a default has already occurred.

A designation of Not Rated or NR is used to denote securities not rated by Fitch where Fitch has rated some, but not all, securities comprising an issuance capital structure.

Rated entities in a number of sectors, including financial and non-financial corporations, sovereigns, insurance companies and certain sectors within public finance, are generally assigned Issuer Default Ratings (IDRs). IDRs are also assigned to certain entities or enterprises in global infrastructure, project finance and public finance. IDRs opine on an entity’s relative vulnerability to default (including by way of a distressed debt exchange) on financial obligations. The threshold default risk addressed by the IDR is generally that of the financial obligations whose non-payment would best reflect the uncured failure of that entity. As such, IDRs also address relative vulnerability to bankruptcy, administrative receivership or similar concepts.

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

Notes: The modifiers “+” or “-” may be appended to a rating to denote relative status within major rating categories.

A short-term issuer or obligation rating is based in all cases on the short-term vulnerability to default of the rated entity and relates to the capacity to meet financial obligations in accordance with the documentation governing the relevant obligation. Short-term deposit ratings may be adjusted for loss severity. Short-Term

Ratings are assigned to obligations whose initial maturity is viewed as “short term” based on market convention. Typically, this means up to 13 months for corporate, sovereign, and structured obligations and up to 36 months for obligations in U.S. public finance markets.

The following specific limitations relate to issuer default scales, ratings assigned to corporate finance obligations, ratings assigned to public finance obligations, ratings assigned to structured finance transactions, ratings assigned to global infrastructure and project finance transactions, ratings assigned for banks (Viability Ratings, Support Ratings, Support Floors), derivative counterparty ratings and insurer financial strength ratings.

The above list is not exhaustive and is provided for the reader’s convenience.

The Boards of Trustees/Directors (the “Directors”) of the closed-end funds advised by BlackRock Advisors, LLC (“BlackRock”) (the “Funds”) have the responsibility for the oversight of voting proxies relating to portfolio securities of the Funds, and have determined that it is in the best interests of the Funds and their shareholders to delegate that responsibility to BlackRock as part of BlackRock’s authority to manage, acquire and dispose of account assets, all as contemplated by the Funds’ respective investment management agreements.

BlackRock has adopted guidelines and procedures (together and as from time to time amended, the “BlackRock Proxy Voting Guidelines”) governing proxy voting by accounts managed by BlackRock. BlackRock will cast votes on behalf of each of the Funds on specific proxy issues in respect of securities held by each such Fund in accordance with the BlackRock Proxy Voting Guidelines; provided, however, that in the case of underlying closed-end funds (including business development companies and other similarly-situated asset pools) held by the Funds that have, or are proposing to adopt, a classified board structure, BlackRock will typically (a) vote in favor of proposals to adopt classification and against proposals to eliminate classification, and (b) not vote against directors as a result of their adoption of a classified board structure.

BlackRock will report on an annual basis to the Directors on (1) a summary of all proxy votes that BlackRock has made on behalf of the Funds in the preceding year together with a representation that all votes were in accordance with the BlackRock Proxy Voting Guidelines (as modified pursuant to the immediately preceding paragraph), and (2) any changes to the BlackRock Proxy Voting Guidelines that have not previously been reported.

BlackRock helps investors build better financial futures. As a fiduciary to our clients, we provide the investment and technology solutions they need when planning for their most important goals. We manage assets on behalf of institutional and individual clients, across a full spectrum of investment strategies, asset classes and regions. Our client base includes pension plans, endowments, foundations, charities, official institutions, insurers and other financial institutions, as well as individuals around the world.

BlackRock’s Investment Stewardship activities are focused on protecting and enhancing the economic value of the companies in which we invest on behalf of clients. We do this through engagement with boards and management of investee companies and, for those clients who have given us authority, through voting at shareholder meetings.

We believe that there are certain fundamental rights attached to shareholding. Companies and their boards should be accountable to shareholders and structured with appropriate checks and balances to ensure that they operate in shareholders’ best interests. Effective voting rights are central to the rights of ownership and there should be one vote for one share. Shareholders should have the right to elect, remove and nominate directors, approve the appointment of the auditor and to amend the corporate charter or by-laws. Shareholders should be able to vote on matters that are material to the protection of their investment including but not limited to changes to the purpose of the business, dilution levels and pre-emptive rights, and the distribution of income and capital structure. In order to make informed decisions, we believe that shareholders have the right to sufficient and timely information.

Our primary focus is on the performance of the board of directors. As the agent of shareholders, the board should set the company’s strategic aims within a framework of prudent and effective controls, which enables risk to be assessed and managed. The board should provide direction and leadership to management and oversee management’s performance. Our starting position is to be supportive of boards in their oversight efforts on shareholders’ behalf and we would generally expect to support the items of business they put to a vote at shareholder meetings. Votes cast against or withheld from resolutions proposed by the board are a signal that we are concerned that the directors or management have either not acted in the best interests of shareholders or have not responded adequately to shareholder concerns. We assess voting matters on a case-by-case basis and in light of each company’s unique circumstances taking into consideration regional best practices and long-term value creation.

These principles set out our approach to engaging with companies, provide guidance on our position on corporate governance and outline how our views might be reflected in our voting decisions. Corporate governance practices can vary internationally, so our expectations in relation to individual companies are based on the legal and regulatory framework of each local market. However, we believe there are overarching principles of corporate governance that apply globally and provide a framework for more detailed, market-specific assessments.

We believe BlackRock has a responsibility in relation to monitoring and providing feedback to companies, sometimes known as “stewardship.” These ownership responsibilities include engaging with management or board members on corporate governance matters, voting proxies in the best long-term economic interests of shareholders and engaging with regulatory bodies to ensure a sound policy framework consistent with promoting long-term shareholder value creation. We also believe in the responsibility to our clients to have appropriate resources and oversight structures. Our approach is set out in the section below titled “BlackRock’s oversight of its investment stewardship activities” and is further detailed in a team profile on our website

We recognize that accepted standards of corporate governance differ between markets, but we believe there are sufficient common threads globally to identify an overarching set of principles. The objective of our investment stewardship activities is the protection and enhancement of the value of our clients’ investments in public corporations. Thus, these principles focus on practices and structures that we consider to be supportive of long-term value creation. We discuss below the principles under six key themes. In our regional and market-specific voting guidelines we explain how these principles inform our voting decisions in relation to specific resolutions that may appear on the agenda of a shareholder meeting in the relevant market.

At a minimum, we expect companies to observe the accepted corporate governance standards in their domestic market or to explain why doing so is not in the interests of shareholders. Where company reporting and disclosure is inadequate or the approach taken is inconsistent with our view of what is in the best interests of shareholders, we will engage with the company and/or use our vote to encourage a change in practice. In making voting decisions, we perform independent research and analysis, such as reviewing relevant information published by the company and apply our voting guidelines to achieve the outcome we believe best protects our clients’ long-term economic interests. We also work closely with our active portfolio managers, and may take into account internal and external research.

BlackRock views engagement as an important activity; engagement provides us with the opportunity to improve our understanding of investee companies and their governance structures to better inform our voting decisions. Engagement also allows us to share our philosophy and approach to investment and corporate governance with companies to enhance their understanding of our objectives. Our engagements often focus on providing our feedback on company disclosures, particularly where we believe they could be enhanced. There are a range of approaches we may take in engaging companies depending on the nature of the issue under consideration, the company and the market.

BlackRock takes an engagement-first approach, emphasizing direct dialogue with companies on governance issues that have a material impact on financial performance. We generally prefer to engage in the first instance where we have concerns and give management time to address or resolve the issue. As a long-term investor, we are patient and persistent in working with our portfolio companies to have an open dialogue and develop mutual understanding of governance matters, to promote the adoption of best practices and to assess the merits of a company’s approach to its governance. We monitor the companies in which we invest and engage with them constructively and privately where we believe doing so helps protect shareholders’ interests. We do not try to micro-manage companies, or tell management and boards what to do. We present our views as a long-term shareholder and listen to companies’ responses. The materiality and immediacy of a given issue will generally determine the level of our engagement and whom we seek to engage at the company, which could be management representatives or board directors.

The performance of the board is critical to the economic success of the company and to the protection of shareholders’ interests. Board members serve as agents of shareholders in overseeing the strategic direction and operation of the company. For this reason, BlackRock focuses on directors in many of our engagements and sees the election of directors as one of our most important responsibilities in the proxy voting context.

We expect the board of directors to promote and protect shareholder interests by:

There should be clear definitions of the role of the board, the committees of the board and senior management such that the responsibilities of each are well understood and accepted. Companies should report publicly the approach taken to governance (including in relation to board structure) and why this approach is in the best interest of shareholders. We will seek to engage with the appropriate directors where we have concerns about the performance of the board or the company, the broad strategy of the company, or the performance of individual board members.

BlackRock believes that directors should stand for re-election on a regular basis. We assess directors nominated for election or re-election in the context of the composition of the board as a whole. There should be detailed disclosure of the relevant credentials of the individual directors in order for shareholders to assess the caliber of an individual nominee. We expect there to be a sufficient number of independent directors on the board to ensure the protection of the interests of all shareholders. Common impediments to independence may include but are not limited to:

BlackRock believes that the operation of the board is enhanced when there is a clearly independent, senior non-executive director to chair it or, where the chairman is also the CEO (or is otherwise not independent), an independent lead director. The role of this director is to enhance the effectiveness of the independent members of the board through shaping the agenda, ensuring adequate information is provided to the board and encouraging independent participation in board deliberations. The lead independent board director should be available to shareholders in those situations where a director is best placed to explain and justify a company’s approach. To ensure that the board remains effective, regular reviews of board performance should be carried out and assessments made of gaps in skills or experience amongst the members. BlackRock believes it is beneficial for new directors to be brought onto the board periodically to refresh the group’s thinking and to ensure both continuity and adequate succession planning. In identifying potential candidates, boards should take into consideration the multiple dimensions of diversity, including personal factors such as gender, ethnicity, and age;

as well as professional characteristics, such as a director’s industry, area of expertise, and geographic location. The board should review these dimensions of the current directors and how they might be augmented by incoming directors. We believe that directors are in the best position to assess the optimal size for the board, but we would be concerned if a board seemed too small to have an appropriate balance of directors or too large to be effective.

There are matters for which the board has responsibility that may involve a conflict of interest for executives or for affiliated directors. BlackRock believes that shareholders’ interests are best served when the board forms committees of fully independent directors to deal with such matters. In many markets, these committees of the board specialize in audit, director nominations and compensation matters. An ad hoc committee might also be formed to decide on a special transaction, particularly one with a related party or to investigate a significant adverse event.

BlackRock recognizes the critical importance of financial statements, which should provide a true and fair picture of a company’s financial condition. We will hold the members of the audit committee or equivalent responsible for overseeing the management of the audit function. We take particular note of cases involving significant financial restatements or ad hoc notifications of material financial weakness.

The integrity of financial statements depends on the auditor being free of any impediments to being an effective check on management. To that end, we believe it is important that auditors are, and are seen to be, independent. Where the audit firm provides services to the company in addition to the audit, the fees earned should be disclosed and explained. Audit committees should have in place a procedure for assessing annually the independence of the auditor.

The capital structure of a company is critical to its owners, the shareholders, as it impacts the value of their investment and the priority of their interest in the company relative to that of other equity or debt investors. Pre-emptive rights are a key protection for shareholders against the dilution of their interests.

Effective voting rights are central to the rights of ownership and we believe strongly in one vote for one share as a guiding principle that supports good corporate governance. Shareholders, as the residual claimants, have the strongest interest in protecting company value, and voting power should match economic exposure.

We are concerned that the creation of a dual share class may result in an over-concentration of power in the hands of a few shareholders, thus disenfranchising other shareholders and amplifying the potential conflict of interest, which the one share, one vote principle is designed to mitigate. However, we recognize that in certain circumstances, companies may have a valid argument for dual-class listings, at least for a limited period of time. We believe that such companies should review these dual-class structures on a regular basis or as company circumstances change. Additionally, they should receive shareholder approval of their capital structure on a periodic basis via a management proposal in the company’s proxy. The proposal should give unaffiliated shareholders the opportunity to affirm the current structure or establish mechanisms to end or phase out controlling structures at the appropriate time, while minimizing costs to shareholders.

In assessing mergers, asset sales or other special transactions, BlackRock’s primary consideration is the long-term economic interests of shareholders. Boards proposing a transaction need to clearly explain the economic and strategic rationale behind it. We will review a proposed transaction to determine the degree to which it enhances long-term shareholder value. We would prefer that proposed transactions have the unanimous support of the board and have been negotiated at arm’s length. We may seek reassurance from the board that executives’ and/or board members’ financial interests in a given transaction have not adversely affected their ability to place shareholders’ interests before their own.

Where the transaction involves related parties, we would expect the recommendation to support it to come from the independent directors and it is good practice to be approved by a separate vote of the non- conflicted shareholders.

BlackRock believes that shareholders have a right to dispose of company shares in the open market without unnecessary restriction. In our view, corporate mechanisms designed to limit shareholders’ ability to sell their shares are contrary to basic property rights. Such mechanisms can serve to protect and entrench interests other than those of the shareholders. We believe that shareholders are broadly capable of making decisions in their own best interests. We expect any so-called ‘shareholder rights plans’ proposed by a board to be subject to shareholder approval upon introduction and periodically thereafter for continuation.

BlackRock expects a company’s board of directors to put in place a compensation structure that incentivizes and rewards executives appropriately and is aligned with shareholder interests, particularly generating sustainable long-term shareholder returns. We would expect the compensation committee to take into account the specific circumstances of the company and the key individuals the board is trying to incentivize. We encourage companies to ensure that their compensation plans incorporate appropriate and challenging performance conditions consistent with corporate strategy and market practice. We use third party research, in addition to our own analysis, to evaluate existing and proposed compensation structures. We hold members of the compensation committee or equivalent board members accountable for poor compensation practices or structures.

BlackRock believes that there should be a clear link between variable pay and company performance that drives shareholder returns. We are not supportive of one-off or special bonuses unrelated to company or individual performance. We acknowledge that the use of peer group evaluation by compensation committees can help ensure competitive pay; however we are concerned when increases in total compensation at a company are justified solely on peer benchmarking rather than outperformance. We support incentive plans that foster the sustainable achievement of results relative to competitors. The vesting timeframes associated with incentive plans should facilitate a focus on long-term value creation. We believe consideration should be given to building claw back provisions into incentive plans such that executives would be required to forgo rewards when they are not justified by actual performance.

Compensation committees should guard against contractual arrangements that would entitle executives to material compensation for early termination of their contract. Finally, pension contributions and other deferred compensation arrangements should be reasonable in light of market practice.

Non-executive directors should be compensated in a manner that is commensurate with the time and effort expended in fulfilling their professional responsibilities. Additionally, these compensation arrangements should not risk compromising their independence or aligning their interests too closely with those of the management, whom they are charged with overseeing.

It is within this context of our fiduciary duty to clients that we undertake our investment stewardship activities. Sound practices in relation to the material environmental and social (“E&S”) factors inherent in the business model can be a signal of operational excellence and management quality.

BlackRock expects companies to identify and report on the material, business-specific E&S risks and opportunities and to explain how these are managed. This explanation should make clear how the approach taken by the company best serves the interests of shareholders and protects and enhances the long-term economic value of the company. E&S factors are material if they are core to how the business operates. The key performance indicators in relation to E&S factors should also be disclosed and performance against them discussed, along

with any peer group benchmarking and verification processes in place. This helps shareholders assess how well management is dealing with the material E&S factors relevant to the business. Any generally recognized best practices and reporting standards adopted by the company should also be discussed in this context.

We do not see it as our role to make social or political judgments on behalf of clients. Our consideration of these E&S factors is consistent with protecting the long-term economic interest of our clients’ assets. We expect investee companies to comply, at a minimum, with the laws and regulations of the jurisdictions in which they operate. They should explain how they manage situations where local laws or regulations that significantly impact the company’s operations are contradictory or ambiguous to global norms.

Given that E&S factors are often not issues on which a shareholder votes, we will engage directly with the board or management. Engagement on a particular E&S factor is based on our assessment that there are potential material economic ramifications for shareholders over the long-term.

We may vote against the election of directors where we have concerns that a company might not be dealing with material E&S factors appropriately. Sometimes we may reflect such concerns by supporting a shareholder proposal on the issue, where there seems to be either a significant potential threat or realized harm to shareholders’ interests caused by poor management of E&S factors. In deciding our course of action, we will assess whether the company has already taken sufficient steps to address the concern and whether there is a clear and material economic disadvantage to the company if the issue is not addressed.

BlackRock believes that shareholders have a right to timely and detailed information on the financial performance and viability of the companies in which they invest. In addition, companies should also publish information on the governance structures in place and the rights of shareholders to influence these. The reporting and disclosure provided by companies help shareholders assess whether their economic interests have been protected and the quality of the board’s oversight of management. We believe shareholders should have the right to vote on key corporate governance matters, including changes to governance mechanisms, to submit proposals to the shareholders’ meeting and to call special meetings of shareholders.

We hold ourselves to a very high standard in our investment stewardship activities, including proxy voting. This function is executed by a team called BlackRock Investment Stewardship (“BIS”) which is comprised of BlackRock employees who do not have other responsibilities other than their roles in BIS. BIS is considered an investment function. The team does not have sales responsibilities.

BlackRock maintains three regional advisory committees (“Stewardship Advisory Committees”) for (a) the Americas; (b) Europe, the Middle East and Africa (“EMEA”); and (c) Asia-Pacific, generally consisting of senior BlackRock investment professionals and/or senior employees with practical boardroom experience. The regional Stewardship Advisory Committees review and advise on amendments to the proxy voting guidelines covering markets within each respective region (“Guidelines”).

In addition to the regional Stewardship Advisory Committees, the Investment Stewardship Global Oversight Committee (“Global Committee”) is a risk-focused committee, comprised of senior representatives from various BlackRock investment teams, BlackRock’s Deputy General Counsel, the Global Head of Investment Stewardship (“Global Head”), and other senior executives with relevant experience and team oversight.

The Global Head has primary oversight of the activities of BIS, including voting in accordance with the Guidelines, which require the application of professional judgment and consideration of each company’s unique circumstances. The Global Committee reviews and approves amendments to these Global Corporate Governance & Engagement Principles. The Global Committee also reviews and approves amendments to the regional Guidelines, as proposed by the regional Stewardship Advisory Committees.

In addition, the Global Committee receives and reviews periodic reports regarding the votes cast by BIS, as well as regular updates on material process issues, procedural changes and other risk oversight considerations. The Global Committee reviews these reports in an oversight capacity as informed by the BIS corporate governance engagement program and Guidelines.

BIS carries out engagement with companies, monitors and executes proxy votes, and conducts vote operations (including maintaining records of votes cast) in a manner consistent with the relevant Guidelines. BIS also conducts research on corporate governance issues and participates in industry discussions to keep abreast of important developments in the corporate governance field. BIS may utilize third parties for certain of the foregoing activities and performs oversight of those third parties. BIS may raise complicated or particularly controversial matters for internal discussion with the relevant investment teams and/or refer such matters to the appropriate regional Stewardship Advisory Committees for review, discussion and guidance prior to making a voting decision.

We carefully consider proxies submitted to funds and other fiduciary account(s) (“Fund” or “Funds”) for which we have voting authority. BlackRock votes (or refrains from voting) proxies for each Fund for which we have voting authority based on our evaluation of the best long-term economic interests of shareholders, in the exercise of our independent business judgment, and without regard to the relationship of the issuer of the proxy (or any shareholder proponent or dissident shareholder) to the Fund, the Fund’s affiliates (if any), BlackRock or BlackRock’s affiliates, or BlackRock employees (see “Conflicts management policies and procedures”, below).

When exercising voting rights, BlackRock will normally vote on specific proxy issues in accordance with the Guidelines for the relevant market. The Guidelines are reviewed regularly and are amended consistent with changes in the local market practice, as developments in corporate governance occur, or as otherwise deemed advisable by BlackRock’s Stewardship Advisory Committees. BIS may, in the exercise of their professional judgment, conclude that the Guidelines do not cover the specific matter upon which a proxy vote is required or that an exception to the Guidelines would be in the best long-term economic interests of BlackRock’s clients.

In the uncommon circumstance of there being a vote with respect to fixed-income securities or the securities of privately held issuers, the decision generally will be made by a Fund’s portfolio managers and/or BIS based on their assessment of the particular transactions or other matters at issue.

In certain markets, proxy voting involves logistical issues which can affect BlackRock’s ability to vote such proxies, as well as the desirability of voting such proxies. These issues include but are not limited to: (i) untimely notice of shareholder meetings; (ii) restrictions on a foreigner’s ability to exercise votes; (iii) requirements to vote proxies in person; (iv) “share-blocking” (requirements that investors who exercise their voting rights surrender the right to dispose of their holdings for some specified period in proximity to the shareholder meeting); (v) potential difficulties in translating the proxy; (vi) regulatory constraints; and (vii) requirements to provide local agents with unrestricted powers of attorney to facilitate voting instructions. We are not supportive of impediments to the exercise of voting rights such as shareblocking or overly burdensome administrative requirements.

As a consequence, BlackRock votes proxies on a “best-efforts” basis. In addition, BIS may determine that it is generally in the best interests of BlackRock’s clients not to vote proxies if the costs (including but not limited to

opportunity costs associated with shareblocking constraints) associated with exercising a vote are expected to outweigh the benefit the client would derive by voting on the proposal.

Portfolio managers have full discretion to vote the shares in the Funds they manage based on their analysis of the economic impact of a particular ballot item. Portfolio managers may from time to time reach differing views on how best to maximize economic value with respect to a particular investment. Therefore, portfolio managers may, and sometimes do, vote shares in the Funds under their management differently from one another. However, because BlackRock’s clients are mostly long-term investors with long-term economic goals, ballots are frequently cast in a uniform manner.

BIS maintains the following policies and procedures that seek to prevent undue influence on BlackRock’s proxy voting activity. Such influence might stem from any relationship between the investee company (or any shareholder proponent or dissident shareholder) and BlackRock, BlackRock’s affiliates, a Fund or a Fund’s affiliates, or BlackRock employees. The following are examples of sources of perceived or potential conflicts of interest:

BlackRock has taken certain steps to mitigate perceived or potential conflicts including, but not limited to, the following:

When so authorized, BlackRock acts as a securities lending agent on behalf of Funds. With regard to the relationship between securities lending and proxy voting, BlackRock’s approach is driven by our clients’ economic interests. The decision whether to recall securities on loan to vote is based on a formal analysis of the revenue producing value to clients of loans, against the assessed economic value of casting votes. Generally, we expect that the likely economic value to clients of casting votes would be less than the securities lending income, either because, in our assessment, the resolutions being voted on will not have significant economic consequences or because the outcome would not be affected by BlackRock recalling loaned securities in order to vote. BlackRock also may, in our discretion, determine that the value of voting outweighs the cost of recalling shares, and thus recall shares to vote in that instance.

Periodically, BlackRock reviews our process for determining whether to recall securities on loan in order to vote and may modify it as necessary.

The issue-specific Guidelines published for each region/country in which we vote are intended to summarize BlackRock’s general philosophy and approach to issues that may commonly arise in the proxy voting context in each market where we invest. These Guidelines are not intended to be exhaustive. BIS applies the Guidelines on a case-by-case basis, in the context of the individual circumstances of each company and the specific issue under review. As such, these Guidelines do not indicate how BIS will vote in every instance.

Section 2-418 of the General Corporation Law of the State of Maryland, Article VI of the Registrant’s Articles of Incorporation, Article IV of the Registrant’s Amended and Restated Bylaws and the Investment Management Agreement each provides for indemnification.

(3) Each director and each officer of the Corporation shall be indemnified by the Corporation to the full extent permitted by the General Laws of the State of Maryland, subject to the requirements of the Investment Company Act of 1940, as amended. No amendment of these Articles of Incorporation or repeal of any provision hereof shall limit or eliminate the benefits provided to directors and officers under this provision in connection with any act or omission that occurred prior to such amendment or repeal.

(4) To the fullest extent permitted by the General Laws of the State of Maryland, subject to the requirements of the Investment Company Act of 1940, as amended, no director or officer of the Corporation shall be personally liable to the Corporation or its security holders for money damages. No amendment of these Articles of Incorporation or repeal of any provision hereof shall limit or eliminate the benefits provided to directors and officers under this provision in connection with any act or omission that occurred prior to such amendment or repeal.

Article IV of the Registrant’s Amended and Restated Bylaws provides as follows:

Section 1. No Personal Liability of Directors or Officers. No Director, advisory board member or officer of the Fund shall be subject in such capacity to any personal liability whatsoever to any Person, save only liability to the Fund or its shareholders arising from bad faith, willful misfeasance, gross negligence or reckless disregard for

his or her duty to such Person; and, subject to the foregoing exception, all such Persons shall look solely to the assets of the Fund for satisfaction of claims of any nature arising in connection with the affairs of the Fund. If any Director, advisory board member or officer, as such, of the Fund, is made a party to any suit or proceeding to enforce any such liability, subject to the foregoing exception, such person shall not, on account thereof, be held to any personal liability. Any repeal or modification of the Charter or this Article IV Section 1 shall not adversely affect any right or protection of a Director, advisory board member or officer of the Fund existing at the time of such repeal or modification with respect to acts or omissions occurring prior to such repeal or modification.

(a) The Fund hereby agrees to indemnify each person who is or was a Director, advisory board member or officer of the Fund (each such person being an “Indemnitee”) to the full extent permitted under the Charter. In addition, the Fund may provide greater but not lesser rights to indemnification pursuant to a contract approved by at least a majority of Directors between the Fund and any Indemnitee. Notwithstanding the foregoing no Indemnitee shall be indemnified hereunder against any liability to any person or any expense of such Indemnitee arising by reason of (i) willful misfeasance, (ii) bad faith, (iii) gross negligence, or (iv) reckless disregard of the duties involved in the conduct of the Indemnitee’s position (the conduct referred to in such clauses (i) through (iv) being sometimes referred to herein as “Disabling Conduct”). Furthermore, with respect to any action, suit or other proceeding voluntarily prosecuted by any Indemnitee as plaintiff, indemnification shall be mandatory only if the prosecution of such action, suit or other proceeding by such Indemnitee (A) was authorized by a majority of the Directors or (B) was instituted by the Indemnitee to enforce his or her rights to indemnification hereunder in a case in which the Indemnitee is found to be entitled to such indemnification.

(b) Notwithstanding the foregoing, unless otherwise provided in any agreement relating to indemnification between an Indemnitee and the Fund, no indemnification shall be made hereunder unless there has been a determination (i) by a final decision on the merits by a court or other body of competent jurisdiction before whom the issue of entitlement to indemnification hereunder was brought that such Indemnitee is entitled to indemnification hereunder or, (ii) in the absence of such a decision, by (A) a majority vote of a quorum of those Directors who are both Independent Directors and not parties to the proceeding (“Independent Non-Party Directors”), that the Indemnitee is entitled to indemnification hereunder, or (B) if such quorum is not obtainable or even if obtainable, if such majority so directs, a Special Counsel in a written opinion concludes that the Indemnitee should be entitled to indemnification hereunder.

(c) Subject to any limitations provided by the 1940 Act and the Charter, the Fund shall have the power and authority to indemnify and provide for the advance payment of expenses to employees, agents and other Persons providing services to the Fund or serving in any capacity at the request of the Fund to the full extent permitted for corporations organized under the corporations laws of the state in which the Fund was formed, provided that such indemnification has been approved by a majority of the Directors.

(d) Any repeal or modification of the Charter or Section 2 of this Article IV shall not adversely affect any right or protection of a Director, advisory board member or officer of the Fund existing at the time of such repeal or modification with respect to acts or omissions occurring prior to such repeal or modification.

Section 3. Good Faith Defined; Reliance on Experts. For purposes of any determination under this Article IV, a person shall be deemed to have acted in good faith and in a manner such person reasonably believed to be in the best interests of the Fund, or, with respect to any criminal action or proceeding, to have had no reasonable cause to believe such person’s conduct was unlawful, if such person’s action is based on the records or books of account of the Fund, or on information supplied to such person by the officers of the Fund in the course of their duties, or on the advice of legal counsel for the Fund or on information or records given or reports made to the Fund by an independent certified public accountant or by an appraiser or other expert or agent selected with reasonable care by the Fund. The provisions of this Article IV Section 3 shall not be deemed to be exclusive or to limit in any way the circumstances in which a person may be deemed to have met the applicable standard of

conduct set forth in this Article IV. Each Director and officer or employee of the Fund shall, in the performance of his or her duties, be fully and completely justified and protected with regard to any act or any failure to act resulting from reliance in good faith upon the books of account or other records of the Fund, upon an opinion of counsel selected by the Board of Directors or a committee of the Directors, or upon reports made to the Fund by any of the Fund’s officers or employees or by any advisor, administrator, manager, distributor, dealer, accountant, appraiser or other expert or consultant selected with reasonable care by the Board of Directors or a committee of the Directors, officers or employees of the Fund, regardless of whether such counsel or expert may also be a Director.

Section 4. Survival of Indemnification and Advancement of Expenses. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article IV shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such a person.

Section 5. Insurance. The Directors may maintain insurance for the protection of the Fund’s property, the shareholders, Directors, officers, employees and agents in such amount as the Directors shall deem adequate to cover possible tort liability, and such other insurance as the Directors in their sole judgment shall deem advisable or is required by the 1940 Act.

Section 6. Subrogation. In the event of payment by the Fund to an Indemnitee under the Charter or these Bylaws, the Fund shall be subrogated to the extent of such payment to all of the rights of recovery of the Indemnitee, who shall execute such documents and do such acts as the Fund may reasonably request to secure such rights and to enable the Fund effectively to bring suit to enforce such rights.

Additionally, the Registrant and the other funds in the BlackRock Fixed-Income Complex jointly maintain, at their own expense, E&O/D&O insurance policies for the benefit of its Trustees, officers and certain affiliated persons. The Registrant pays a pro rata portion of the premium on such insurance policies.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to Trustees, officers and controlling persons of the Trust, pursuant to the foregoing provisions or otherwise, the Trust has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a Trustee, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such Trustee, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

BlackRock Advisors, LLC, a limited liability company organized under the laws of Delaware (the “Advisor”), acts as investment adviser to the Registrant. The Registrant is fulfilling the requirement of this Item 31 to provide a list of the officers and directors of the Advisor, together with information as to any other business, profession, vocation or employment of a substantial nature engaged in by the Advisor or those officers and directors during the past two years, by incorporating by reference the information contained in the Form ADV of the Advisor filed with the commission pursuant to the Investment Advisers Act of 1940 (Commission File No. 801-47710).

The Registrant’s accounts, books and other documents are currently located at the offices of the Registrant, c/o BlackRock Advisors, LLC, 100 Bellevue Parkway, Wilmington, DE 19809 and at the offices of State Street Bank and Trust Company, the Registrant’s Custodian and Administrator, at One Lincoln Street, Boston, Massachusetts 02111, The Bank of New York Mellon, the Registrant’s former custodian and transfer agent, at One Wall Street, New York, New York 10286, Computershare Trust Company, N.A., the Registrant’s Transfer Agent, at 250 Royall Street, Canton, Massachusetts 02021, and BNY Mellon Investment Servicing (US) Inc., the Registrant’s former administrator, at One Wall Street, New York, New York 10286.

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

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

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

BBB		An obligation rated ‘BBB’ exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken the obligor’s capacity to meet its financial commitments on the obligation.



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

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

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

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

CC		An obligation rated ‘CC’ is currently highly vulnerable to nonpayment. The ‘CC’ rating is used when a default has not yet occurred but S&P expects default to be a virtual certainty, regardless of the anticipated time to default.

C		An obligation rated ‘C’ is currently highly vulnerable to nonpayment, and the obligation is expected to have lower relative seniority or lower ultimate recovery compared with obligations that are rated higher.

D		An obligation rated ‘D’ is in default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D’ rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within five business days in the absence of a stated grace period or within the earlier of the stated grace period or 30 calendar days. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. A rating on an obligation is lowered to ‘D’ if it is subject to a distressed exchange offer.


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

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

A-3		A short-term obligation rated ‘A-3’ exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken an obligor’s capacity to meet its financial commitments on the obligation.



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

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

D		A short-term obligation rated ‘D’ is in default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D’ rating category is used when payments on an obligation are not made on the date due, unless S&P believes that such payments will be made within any stated grace period. However, any stated grace period longer than five business days will be treated as five business days. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. A rating on an obligation is lowered to ‘D’ if it is subject to a distressed exchange offer.


SP-1		Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus (+) designation.

SP-2		Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

SP-3		Speculative capacity to pay principal and interest.

D		‘D’ is assigned upon failure to pay the note when due, completion of a distressed exchange offer, or the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions.


Aaa		Obligations rated Aaa are judged to be of the highest quality, subject to the lowest level of credit risk.

Aa		Obligations rated Aa are judged to be of high quality and are subject to very low credit risk.

A		Obligations rated A are judged to be upper-medium grade and are subject to low credit risk.

Baa		Obligations rated Baa are judged to be medium-grade and subject to moderate credit risk and as such may possess certain speculative characteristics.

Ba		Obligations rated Ba are judged to be speculative and are subject to substantial credit risk.

B		Obligations rated B are considered speculative and are subject to high credit risk.

Caa		Obligations rated Caa are judged to be speculative of poor standing and are subject to very high credit risk.

Ca		Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.

C		Obligations rated C are the lowest rated and are typically in default, with little prospect for recovery of principal or interest.


P-1		Issuers (or supporting institutions) rated Prime-1 have a superior ability to repay short-term debt obligations.

P-2		Issuers (or supporting institutions) rated Prime-2 have a strong ability to repay short-term debt obligations.

P-3		Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to repay short-term obligations.

NP		Issuers (or supporting institutions) rated Not Prime do not fall within any of the Prime rating categories.


MIG 1		This designation denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support, or demonstrated broad-based access to the market for refinancing.

MIG 2		This designation denotes strong credit quality. Margins of protection are ample, although not as large as in the preceding group.

MIG 3		This designation denotes acceptable credit quality. Liquidity and cash-flow protection may be narrow, and market access for refinancing is likely to be less well-established.

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