21,000,000 Shares

BlackRock Taxable Municipal Bond Trust

Common Shares of Beneficial Interest

Rights to Purchase Common Shares of Beneficial Interest

BlackRock Taxable Municipal Bond Trust (the “Trust,” “we,” “us” or “our”) is a diversified,

closed-end

management investment company. The Trust’s primary investment objective is to seek high current income, with a secondary objective of capital appreciation.

We may offer, from time to time, in one or more offerings, up to 21,000,000 of our common shares of beneficial interest, par value $0.001 per share (“common shares”). We may also offer subscription rights to purchase our common shares. Common shares may be offered at prices and on terms to be set forth in one or more supplements to this Prospectus (each, a “Prospectus Supplement”). 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, including existing shareholders in a rights offering, through agents designated from time to time by us, or to or through underwriters or dealers. The Prospectus Supplement relating to the offering will identify any agents or underwriters 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. 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.

Our common shares are listed on the New York Stock Exchange (“NYSE”) under the symbol “BBN.” The last reported sale price of our common shares, as reported by the NYSE on May 4, 2026 was $16.04 per common share. The net asset value of our common shares at the close of business on May 4, 2026 was $16.91 per common share. Rights issued by the Trust may also be listed on a securities exchange.

Investing in the Trust’s common shares involves certain risks, including the risks of leverage, which are described in the “Risks” section beginning on page 26 of this Prospectus.

Shares of

closed-end

management investment companies frequently trade at a discount to their net asset value. The Trust’s common shares have traded at a discount to net asset value, including during recent periods. If the Trust’s common shares trade at a discount to their net asset value, the risk of loss may increase for purchasers in a public offering.

Neither the Securities and Exchange Commission (“SEC”) nor any state securities commission has approved or disapproved these securities or passed upon the adequacy of this Prospectus. Any representation to the contrary is a criminal offense.

This Prospectus is part of a registration statement that we have filed with the SEC, as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”), using the “shelf” registration process. Under the shelf registration process, we may offer, from time to time, separately or together in one or more offerings, the securities described in this Prospectus. The securities may be offered at

prices and on terms described in one or more supplements to this Prospectus. This Prospectus provides you with a general description of the securities that we may offer. Each time we use this Prospectus to offer securities, we will provide a Prospectus Supplement that will contain specific information about the terms of that offering. The Prospectus Supplement may also add, update or change information contained in this Prospectus. This Prospectus, together with any Prospectus Supplement, sets forth concisely the information about the Trust that a prospective investor should know before investing. You should read this Prospectus and applicable Prospectus Supplement, which contain important information, before deciding whether to invest in the common shares. You should retain this Prospectus and the applicable Prospectus Supplement for future reference.

PROSPECTUS SUMMARY

This summary may not contain all of the information that you should consider before investing in our common shares. You should consider the more detailed information contained in the Prospectus and in any related Prospectus Supplement and in the Statement of Additional Information (“SAI”) before purchasing common shares.


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

		The Trust’s common shares of beneficial interest, par value $0.001 per share (“common shares”), are listed for trading on the New York Stock Exchange (“NYSE”) under the symbol “BBN.” As of May 4, 2026, the net assets of the Trust were $1,044,780,366.07, the total assets of the Trust were $1,590,895,078.57 and the Trust had 61,792,514 common shares outstanding . The last reported sale price of the Trust’s common shares, as reported by the NYSE on May 4, 2026 was $16.04 per common share. The net asset value (“NAV”) of the Trust’s common shares at the close of business on May 4, 2026 was $16.91 per common share. See “Description of Shares.” Rights issued by the Trust may also be listed on a securities exchange.

The Offering		We may offer, from time to time, in one or more offerings, up to 21,000,000 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 .

Use of Proceeds		The net proceeds from the issuance of common shares hereunder will be invested in accordance with our investment objectives 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 Trust; however, the identification of appropriate investment opportunities pursuant to the Trust’s

- 1 -


		investment style or changes in market conditions could result in the Trust’s anticipated investment period extending to as long as six months. Such investments may be delayed if suitable investments are unavailable at the time or for other reasons, such as market volatility and lack of liquidity in the markets of suitable investments. 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 . See “Use of Proceeds.”

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

Leverage		The Trust uses leverage to seek to achieve its investment objectives. The Trust’s use of leverage may increase or decrease from time to time in its discretion and the Trust may, in the future, determine not to use leverage. The Trust currently utilizes leverage for investment purposes primarily by entering into reverse repurchase agreements or other derivative instruments with leverage embedded in them. The Trust currently does not intend to borrow money or issue debt securities or shares of preferred shares (“preferred shares”). Under the Investment Company Act of 1940, as amended (the “Investment Company Act”), the Trust 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), issue preferred shares in an amount up to 50% of its Managed Assets (100% of its net assets) and enter into derivative instruments with leverage embedded in them in a limited manner or subject to a limit on leverage risk calculated based on value-at-risk, as required by Rule 18f-4 under the Investment Company Act. “Managed Assets” means the total assets of the Trust (including any assets attributable to money borrowed for investment purposes) minus the sum of the Trust’s accrued liabilities (other than money borrowed for investment purposes). Although it has no present intention to do so, the Trust 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. Pursuant to Rule 18f-4 under the Investment Company Act, among other things, the Trust must either use derivative financial instruments with embedded leverage in a limited manner or comply with an outer limit on fund leverage risk based on value-at-risk. See “Leverage.”

		As part of its leverage strategy, the Trust may invest in leveraged residual certificates issued by tender option bond (“TOB”) trusts (“TOB Residuals”). The TOB Residuals in which the Trust 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 Trust, 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 Trust may invest in TOB Residuals for the purpose of using leverage as a more flexible alternative to the issuance of preferred shares. See “Leverage—Tender Option Bond Transactions.”

- 2 -


		The use of leverage, if employed, is subject to numerous risks. When leverage is employed, the Trust’s NAV, the market price of the Trust’s 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 generally will cause the Trust’s NAV to decline more than if the Trust had not used leverage. A reduction in the Trust’s NAV may cause a reduction in the market price of the Trust’s common shares.

		The Trust cannot assure you that the use of leverage will result in a higher yield on the Trust’s common shares. In addition, because the Trust’s investment management fee is calculated as a percentage of the Trust’s Managed Assets, which include those assets purchased with leverage, during periods in which the Trust is using leverage, the fee paid to the Advisor will be higher than if the Trust did not use leverage. Any leveraging strategy the Trust employs may not be successful.

Investment Advisor		BlackRock Advisors, LLC is the Trust’s investment adviser. The Advisor receives a monthly fee in arrears at an annual rate equal to 0.55% of the average daily value of the Trust’s Managed Assets. See “Management of the Trust—Investment Advisor.”

Distributions		The Trust intends to make regular monthly cash distributions of all or a portion of its net investment income to holders of the Trust’s common shares. The Trust has, with the approval of the Board of Trustees of the Trust (the “Board”), adopted a managed distribution plan, consistent with its investment objectives and policies, to support a level distribution of income, capital gains and/or return of capital (the “Distribution Plan”). Under the Distribution Plan, the Trust will distribute all available investment income to its shareholders as required by the Code. If sufficient income (inclusive of net investment income and short-term capital gains) is not earned on a monthly basis, the Trust will distribute long-term capital gains and/or return of capital to shareholders in order to maintain a level distribution. A return of capital distribution may involve a return of the shareholder’s original investment. Though not currently taxable, such a distribution may lower a shareholder’s basis in the Trust, thus potentially subjecting the shareholder to future tax consequences in connection with the sale of Trust shares, even if sold at a loss to the shareholder’s original investment. Each monthly distribution to shareholders is expected to be at a fixed amount established by the Board; however, the Trust may make additional distributions from time to time, including additional capital gain distributions at the end of the taxable year, if required to meet requirements imposed by the Code and/or the Investment Company Act. Shareholders should not draw any conclusions about the Trust’s investment performance from the amount of these distributions or from the terms of the Distribution Plan.

		Various factors will affect the level of the Trust’s income, including the asset mix, the average maturity of the Trust’s portfolio, the amount of leverage utilized by the Trust and the Trust’s use of hedging. To permit the Trust to maintain a more stable monthly distribution, the Trust may from time to time distribute less than the entire amount of income earned in a particular period. The undistributed income would be available to supplement future distributions. As a result, the distributions paid by the Trust for any particular monthly period may be more or less than the amount of income actually earned by the Trust during that period. Undistributed income will add to the Trust’s NAV (and indirectly benefits the Advisor by increasing its fee) and, correspondingly,

- 3 -


		distributions from undistributed income will reduce the Trust’s NAV. The Trust intends to distribute any long-term capital gains not distributed under the Distribution Plan annually. Under normal market conditions, the Advisors seek to manage the Trust in a manner such that the Trust’s distributions are reflective of the Trust’s current and projected earnings levels. The distribution level of the Trust is subject to change based upon a number of factors, including the current and projected level of the Trust’s earnings, and may fluctuate over time. The Trust’s Board may amend, suspend or terminate the Distribution Plan at any time without prior notice to the Trust’s shareholders if it deems such actions to be in the best interests of the Trust or its shareholders. See “Distributions.” Shareholders will automatically have all dividends and distributions reinvested in common shares of the Trust in accordance with the Trust’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 Trust’s common shares are listed on the NYSE under the symbol “BBN.” See “Description of Shares—Common Shares.”

Custodian and Transfer Agent		State Street Bank and Trust Company serves as the Trust’s custodian, and Computershare Trust Company, N.A. serves as the Trust’s transfer agent.

Administrator		State Street Bank and Trust Company serves as the Trust’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 Trust cannot assure you that its common shares will trade at a price higher than or equal to NAV. See “Use of Proceeds.” The Trust’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, market sentiment and other factors. See “Leverage,” “Risks,” “Description of Shares” and “Repurchase of Common Shares.” The common shares are designed primarily for long-term investors and you should not purchase common shares of the Trust if you intend to sell them shortly after purchase.

Special Risk Considerations		An investment in common shares of the Trust involves risk. Please refer to the section of the Trust’s most recent annual report on Form N-CSR entitled “Trust Investment Objectives, Policies and Risks—Risk Factors”, which is incorporated by reference herein, for a discussion of the risks of investing in the Trust. You should carefully consider those risks, which are described in more detail under “Risks” beginning on page 25 of this Prospectus, along with additional risks relating to an investment in the Trust.

Anti-Takeover Provisions		The Trust’s Agreement and Declaration of Trust (as defined below) and Bylaws include provisions that could limit the ability of other entities or persons to acquire control of the Trust, to convert the Trust 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 Trust. See “Certain Provisions in the Agreement and Declaration of Trust and Bylaws.”

(1)	If the common shares are sold to or through underwriters, the Prospectus Supplement will set forth any applicable sales load and the estimated offering expenses . Trust shareholders will pay all offering expenses involved with an offering.

(2)

The Reinvestment Plan Agent’s (as defined below under “Dividend Reinvestment Plan”) fees for the handling of the reinvestment of dividends will be paid by the Trust. However, you will pay a $0.02 per share fee incurred in connection with open-market purchases, which will be deducted from the value of the dividend. You will also be charged a $2.50 sales fee and pay a $0.15 per share fee if you direct the Reinvestment Plan Agent to sell your common shares held in a dividend reinvestment account. Per share fees include any applicable brokerage commissions the Reinvestment Plan Agent is required to pay.

(3)

The Trust currently pays the Advisor a monthly fee in arrears at an annual rate equal to 0.55% of the average daily value of the Trust’s Managed Assets. For purposes of calculating this fee, “Managed Assets” are determined as total assets of the Trust (including any assets attributable to money borrowed for investment purposes) less the sum of its accrued liabilities (other than money borrowed for investment purposes).

(4)	The Total Annual Fund Operating Expenses and Miscellaneous Other Expense do not correlate to the ratios of expenses to average net assets given in the Fund’s most recent annual financial statements and additional information, which do not include Acquired Fund Fees and Expenses.

(5)

Assumes the use of leverage in the form of reverse repurchase agreements representing 34.33% of Managed Assets (as defined above) at an annual interest expense to the Trust of 4.51%, which is based on current market conditions. The actual amount of interest expense borne by the Trust will vary over time in accordance with the level of the Trust’s use of reverse repurchase agreements and variations in market interest rates. Interest expense is required to be treated as an expense of the Trust for accounting purposes.

(6)

The Trust 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 investment advisory fees with respect to any portion of the Trust’s assets attributable to investments in any equity and fixed-income mutual funds and ETFs managed by the Advisor or its affiliates and other exchange-traded products sponsored by the Advisor or its affiliates, in each case that have a contractual management fee, through June 30, 2028. In addition, pursuant to the Fee Waiver Agreement, the Advisor has contractually agreed to waive its investment advisory fees by the amount of investment advisory fees the Trust pays to the Advisor indirectly through its investment in money market funds managed by the Advisor or its affiliates, through June 30, 2028. The Fee Waiver Agreement may be continued from year to year thereafter, provided that such continuance is specifically approved by the Advisor and the Trust (including by a majority of the Trust’s Independent Trustees). Neither the Advisor nor the Trust 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 Trust (upon the vote of a majority of the Independent Trustees or a majority of the outstanding voting securities of the Trust), upon 90 days’ written notice by the Trust to the Advisor.

The following example illustrates the expenses (including the sales load of $10.00 and offering costs of $0.19 that you would pay on a $1,000 investment in common shares, assuming (i) the Fee Waiver Agreement described above is only in effect for the first year, since it expires on June 30, 2028, and (ii) a 5% annual return:


	One Year		Three Years		Five Years		Ten Years
Total expenses incurred	$	41	$	105	$	172	$	349

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, that the rate listed under Total Annual Expenses remains the same each year and that all dividends and distributions are reinvested at NAV. Actual expenses may be greater or less than those assumed. Moreover, the Trust’s actual rate of return may be greater or less than the hypothetical 5% return shown in the example.

USE OF PROCEEDS

The net proceeds from the issuance of common shares hereunder will be invested in accordance with the Trust’s investment objectives 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 objectives and policies within approximately three months from the date on which the proceeds from an offering are received by the Trust; however, the identification of appropriate investment opportunities pursuant to the Trust’s investment style or changes in market conditions could result in the Trust’s anticipated investment period extending to as long as six months. Such investments may be delayed if suitable investments are unavailable at the time or for other reasons, such as market volatility and lack of liquidity in the markets of suitable investments. 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 TRUST

The Trust is a diversified,

closed-end

management investment company registered under the Investment Company Act. The Trust was formed as a Delaware statutory trust on June 7, 2010 pursuant to an Agreement and Declaration of Trust governed by the laws of the State of Delaware and the Certificate of Trust filed with the Secretary of State of the State of Delaware. The Trust was known as “BlackRock Build America Bond Trust” prior to August 10, 2015. The Trust’s principal office is located at 100 Bellevue Parkway, Wilmington, Delaware 19809, and its telephone number is (800)

882-0052.

The Trust commenced operations on August 27, 2010, upon the initiation of an initial public offering of 50,750,00 of its common shares. The proceeds of such offering were approximately $967.295 million after the payment of organizational and offering expenses. The Trust’s common shares are traded on the NYSE under the symbol “BBN.”

DESCRIPTION OF SHARES

Common Shares

The Trust is a statutory trust formed under the laws of Delaware and governed by an Amended and Restated Agreement and Declaration of Trust dated as of July 16, 2010 as amended by the Amendment thereto effective as of August 25, 2015 (as so amended, the “Agreement and Declaration of Trust”). The Trust is authorized to issue an unlimited number of common shares of beneficial interest, par value $0.001 per share. Each common share has one vote and, when issued and paid for in accordance with the terms of this offering, will be fully paid and, under the Delaware Statutory Trust Act, the purchasers of the common shares will have no obligation to make further payments for the purchase of the common shares or contributions to the Trust solely by reason of their ownership of the common shares, except that the Trustees shall have the power to cause shareholders to pay certain expenses of the Trust by setting off charges due from shareholders from declared but unpaid dividends or distributions owed the shareholders and/or by reducing the number of common shares owned by each respective shareholder. If and whenever preferred shares are outstanding, the holders of common shares will not be entitled to receive any distributions from the Trust unless all accrued dividends on preferred shares have been paid, unless asset coverage (as defined in the Investment Company Act) with respect to preferred shares would be at least 200% after giving effect to the distributions and unless certain other requirements imposed by any rating agencies rating the preferred shares have been met. See “Description of Shares—Preferred Shares” in the SAI. All common shares are equal as to dividends, assets and voting privileges and have no conversion, preemptive or other subscription rights. The Trust will send annual and semi-annual reports, including financial statements, to all holders of its shares.

Unlike

open-end

funds,

closed-end

funds like the Trust 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

- 9 -

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

closed-end

investment companies like the Trust 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 Trust’s NAV, relative demand for and supply of such shares in the market, general market and economic conditions, market sentiment and other factors beyond the control of the Trust, the Trust cannot assure you that its common shares will trade at a price equal to or higher than NAV in the future. The common shares are designed primarily for long-term investors and you should not purchase the common shares if you intend to sell them soon after purchase. See “Repurchase of Common Shares” below and “Repurchase of Common Shares” in the SAI.

The Trust’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 “BBN.” The Trust 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 May 4, 2026, the NAV per common share of the Trust was $16.91 and the market price per common share was $16.04, representing a discount to NAV of (5.14)%. Common shares of the Trust have historically traded at both a premium and discount to NAV.

Preferred Shares

The Agreement and Declaration of Trust provides that the Board may authorize and issue preferred shares, with rights as determined by the Board, by action of the Board without the approval of the holders of the common shares. Holders of common shares have no preemptive right to purchase any preferred shares that might be issued. The Trust does not currently intend to issue preferred shares. Under the Investment Company Act, the Trust is not permitted to issue preferred shares unless immediately after such issuance the value of the Trust’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 Trust’s total assets). In addition, the Trust 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 Trust’s total assets is at least 200% of such liquidation value. If the Trust 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 Trust. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Trust by the Investment Company Act. It is not

- 10 -

anticipated that these covenants or guidelines would impede the Advisor from managing the Trust’s portfolio in accordance with the Trust’s investment objectives and policies. Please see “Description of Shares” in the SAI for more information.

THE TRUST’S INVESTMENTS

Investment Objectives and Policies

Please refer to the section of the Trust’s most recent annual report on Form

N-CSR

entitled “Trust Investment Objectives, Policies and Risks—Investment Objectives and Policies”, which is incorporated by reference herein, for a discussion of the Trust’s investment objectives and policies.

Description of Municipal Securities

Set forth below is a detailed description of the municipal securities in which the Trust invests. Information with respect to ratings assigned to

tax-exempt

obligations that the Trust may purchase is set forth in “Appendix A—Ratings of Investments” in the SAI. Obligations are included within the term municipal securities if the interest paid thereon is excluded from gross income for federal income tax purposes in the opinion of bond counsel to the issuer.

Build America Bonds “BABs.”

BABs are taxable municipal securities issued by state and local governments. Municipal securities include, among other things, bonds, notes, leases and certificates of participation. Municipal securities may be structured as callable or

non-callable,

may have payment forms that include fixed-coupon, variable rate and zero coupon, and may include capital appreciation bonds, floating rate securities, inverse floating rate securities (including TOB Residuals), inflation-linked securities and other derivative instruments that replicate investment exposure to such securities. BABs, as municipal securities, may be structured in any of the foregoing ways and new versions of BABs may be offered in the future. The Trust may invest in any of these BABs or municipal securities, and may acquire them through investments in pooled vehicles, partnerships or other investment companies. The Trust may also purchase BABs and other municipal securities representing a wide range of sectors and purposes.

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

pre-1986

law) are issued by or on behalf of public authorities to finance various privately owned or operated facilities, including among other things, airports, public ports, mass commuting facilities, multi-family housing projects, as well as facilities for water supply, gas, electricity, sewage or solid waste disposal and other specialized facilities. Other types of PABs, the proceeds of which are used for the construction, equipment or improvement of privately operated industrial or commercial facilities, may constitute municipal securities. The interest on municipal securities may bear a fixed

- 11 -

rate or be payable at a variable or floating rate. The two principal classifications of municipal securities are “general obligation” bonds and “revenue” bonds, which latter category includes PABs. Municipal securities typically are issued to finance public projects, such as roads or public buildings, to pay general operating expenses or to refinance outstanding debt. Municipal securities may also be issued for private activities, such as housing, medical and educational facility construction, or for privately owned industrial development and pollution control projects. General obligation bonds are backed by the full faith and credit, or taxing authority, of the issuer and may be repaid from any revenue source. Revenue bonds may be repaid only from the revenues of a specific facility or source. Municipal securities may be issued on a long-term basis to provide permanent financing. The repayment of such debt may be secured generally by a pledge of the full faith and credit taxing power of the issuer, a limited or special tax, or any other revenue source, including project revenues, which may include tolls, fees and other user charges, lease payments and mortgage payments. Municipal securities may also be issued to finance projects on a short-term interim basis, anticipating repayment with the proceeds of the later issuance of long-term debt.

Certain municipal securities in which the Trust 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 or income paid by municipal securities held by the Trust, but will rely on the opinion of counsel to the issuer of each such instrument. The Trust may also invest in municipal securities 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 securities described in this Prospectus, the Trust 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 Trust treats all of such

tax-exempt

securities as municipal securities.

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

The Trust has not established any limit on the percentage of its portfolio that may be invested in PABs. The Trust 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 Trust’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

- 12 -

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 Trust 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 Trust 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 Trust may purchase municipal securities 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 Trust. 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 securities, 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 securities 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 securities 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 pay lease obligations. Certain investments in lease obligations may be illiquid.

- 13 -

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 Trust, 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 Trust. Issuers of municipal lease obligations might seek protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, the Trust could experience delays and limitations with respect to the collection of principal and interest on such municipal leases and the Trust 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 Trust might take possession of and manage the assets securing the issuer’s obligations on such securities, which may increase the Trust’s operating expenses and adversely affect the NAV of the Trust. When the lease contains a

non-appropriation

clause, however, the failure to pay would not be a default and the Trust would not have the right to take possession of the assets. Any income derived from the Trust’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 Trust’s intention to qualify as a regulated investment company under the Code may limit the extent to which the Trust may exercise its rights by taking possession of such assets, because as a regulated investment company the Trust is subject to certain limitations on its investments and on the nature of its income.

Zero-Coupon Bonds

. Municipal securities 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 Trust 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.

Further, to maintain its qualification for pass-through treatment under the federal tax laws, the Trust 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 Trust’s exposure to

zero-coupon

bonds.

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 Trust’s investment exposure to these securities and their risks, including credit risk, will increase during the time these securities are held in the Trust’s portfolio.

- 14 -

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 Trust may invest in municipal securities (and

Non-Municipal

Tax-Exempt

Securities) that yield a return based on a particular index of value or interest rates. For example, the Trust may invest in municipal securities that pay interest based on an index of municipal security interest rates. The principal amount payable upon maturity of certain municipal securities also may be based on the value of the index. To the extent the Trust invests in these types of municipal securities, the Trust’s return on such municipal securities will be subject to risk with respect to the value of the particular index. Interest and principal payable on the municipal securities may also be based on relative changes among particular indices. Also, the Trust 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 Trust 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 Trust 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 Trust’s Investments—Leverage—Tender Option Bond Transactions.”

When-Issued Securities, Delayed Delivery Securities and Forward Commitments

. The Trust may purchase or sell securities that it is entitled to receive on a when-issued basis. The Trust may also purchase or sell securities on a delayed delivery basis. The Trust may also purchase or sell securities through a forward commitment. These transactions involve the purchase or sale of securities by the Trust at an established price with payment and delivery taking place in the future. The purchase will be recorded on the date the Trust enters into the

- 15 -

commitment and the value of the securities will thereafter be reflected in the Trust’s NAV. The Trust has not established any limit on the percentage of its assets that may be committed in connection with these transactions.

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 Trust 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 Trust’s purchase price. The Trust 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 Trust 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 Trust on the settlement date. In these cases the Trust may realize a taxable capital gain or loss.

When the Trust 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 Trust’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 Trust starting on the day the Trust agrees to purchase the securities. The Trust does not earn interest on the securities it has committed to purchase until they are paid for and delivered on the settlement date.

Rule

18f-4

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

non-standard

settlement cycle securities notwithstanding the limitation on the issuance of senior securities in Section 18 of the Investment Company Act, provided that the Trust intends to physically settle the transaction and the transaction will settle within 35 days of its trade date (the “Delayed-Settlement Securities Provision”). If a when-issued, forward-settling or

non-standard

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

18f-4.

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

18f-4

Under the Investment Company Act” in the SAI.

Yields

. Yields on municipal securities are dependent on a variety of factors, including the general condition of the money market and of the municipal security 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 Trust to achieve its investment objective is also dependent on the continuing ability of the issuers of the securities in which the Trust invests to meet their obligations for the payment of interest and principal when due. There are variations in the risks involved in holding municipal securities, both within a particular classification and between classifications, depending on numerous factors. Furthermore, the rights of owners of municipal securities and the obligations of the issuer of such municipal securities 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 Trust may invest up to 20% of its Managed Assets in securities rated below investment grade such as those rated Ba or below by Moody’s and BB or below by S&P or Fitch or in unrated securities determined by the Advisor to be of comparable quality. Information with respect to ratings assigned to

tax-exempt

obligations that the Trust may purchase is set forth in “Appendix A—Ratings of Investments” in the SAI. Municipal securities 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.

- 16 -

Strategic Transactions

The Trust may engage in various strategic transactions for hedging and risk management purposes or to enhance total return (“Strategic Transactions”). Strategic Transactions involve the use of derivative instruments. Such instruments may include, but are not limited to, financial futures contracts, swap contracts (including, but not limited to, credit default swaps), options on financial futures, options on swap contracts and other derivative instruments. If the Trust engages in Strategic Transactions for hedging and risk management purposes, it primarily intends to use strategies that include swaps (including interest rate swaps), financial futures contracts, options on financial futures or options based either on an index of long-term securities or on taxable debt securities whose prices, in the opinion of the Advisor, correlate with the prices of the Trust’s investments. If the Trust engages in Strategic Transactions to enhance total return, it primarily intends to use the same strategies as discussed above for hedging and risk management purposes and, in addition, to engage in credit derivative transactions, including credit default swaps. There is no assurance that these derivative strategies will be available at any time or that the Advisor will determine to use them for hedging or risk management purposes or to enhance total return or, if used, that the strategies will be successful.

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 Trust 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 Trust to the risk that, if the Advisor incorrectly forecasts market values, interest rates or other applicable factors, the Trust’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 Trust’s portfolio. The Trust 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 Trust to sell or purchase portfolio securities at inopportune times or for prices other than current market values, may limit the amount of appreciation the Trust can realize on an investment or may cause the Trust to hold a security that it might otherwise sell. Furthermore, the Trust 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.

Certain federal income tax requirements may restrict or affect the ability of the Trust 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 Trust 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 Trust 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 Trust’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 Trust against an increase in the price of a security that it intended to purchase in the future.

Writing Covered Call Options

. The Trust is authorized to write (i.e., sell) covered call options with respect to municipal securities it owns, thereby giving the holder of the option the right to buy the underlying security covered by the option from the Trust at the stated exercise price until the option expires. The Trust writes only

- 17 -

covered call options, which means that so long as the Trust is obligated as the writer of a call option, it will own the underlying securities subject to the option.

The Trust receives a premium from writing a call option, which increases the Trust’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 Trust 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 Trust’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 Trust may engage in closing transactions in order to terminate outstanding options that it has written.

Additional Information About Options

. The Trust’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 Trust. With OTC options, such variables as expiration date, exercise price and premium will be agreed upon between the Trust 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 Trust 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 Trust are considered by the staff of the Securities and Exchange Commission (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 Trust may engage in options and futures transactions on exchanges and options in the

over-the-counter

markets. The Trust 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 Trust 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 Trust’s return. However, any transactions involving financial futures or options (including puts and calls associated therewith) will be in accordance with the Trust’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 Trust 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

- 18 -

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

The Trust 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 securities in which the Trust invests to make such hedging appropriate.

Futures Strategies

. The Trust 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 Trust’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 Trust’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 Trust’s investments that are being hedged. While the Trust 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 Trust’s investments being hedged. In addition, the ability of the Trust 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 Trust. Employing futures as a hedge also may permit the Trust to assume a defensive posture without reducing the yield on its investments beyond any amounts required to engage in futures trading.

- 19 -

When the Trust intends to purchase a security, the Trust 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 Trust. 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 Trust 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 Trust may purchase a call option on a futures contract to hedge against a market advance when the Trust 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 Trust will retain the full amount of the option premium, which provides a partial hedge against any decline that may have occurred in the Trust’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 Trust may purchase a put option on a futures contract to hedge the Trust’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 Trust will retain the full amount of the option premium, which provides a partial hedge against any increase in the price of securities which the Trust 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 Trust 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 Trust.

Counterparty Credit Standards

. To the extent that the Trust 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 Trust 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 Trust 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 Trust’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 Trust to provide collateral to secure its performance obligations under a contract, which would also entail counterparty credit risk.

LEVERAGE

The Trust intends to use leverage to seek to achieve its investment objectives. The Trust’s use of leverage may increase or decrease from time to time in its discretion and the Trust may, in the future, determine not to use leverage. The Trust currently utilizes leverage for investment purposes primarily by entering into reverse repurchase agreements or other derivative instruments with leverage embedded in them. The Trust currently does not intend to borrow money or issue debt securities or preferred shares. The Trust is permitted to borrow money (including by investing in reverse repurchase agreements and TOB Residuals) or issue debt securities in an amount up to 33 1/3% of its managed assets (50% of its net assets), issue preferred shares in an amount up to 50% of its managed assets (100% of its net assets) and enter into derivative instruments with leverage embedded in them in a limited manner or subject to a limit on leverage risk calculated based on

value-at-risk,

as required by Rule

18f-4

under the Investment Company Act. Although it has no present intention to do so, the Trust reserves the right to borrow money from banks or other financial institutions, or issue debt securities, 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. Any such leveraging will not be fully achieved until the proceeds resulting from the use of leverage have been invested in accordance with the Trust’s investment objectives and policies).

The use of leverage, including investments in reverse repurchase agreements and TOBs Residuals, 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 Trust’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 Trust’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 Trust did not utilize leverage. A reduction in the Trust’s NAV may cause a reduction in the market price of its shares. During periods in which the Trust is using leverage, the fee paid to the Advisor for advisory services will be higher than if the Trust did not use leverage, because the fees paid will be calculated on the basis of the Trust’s Managed Assets, which includes the proceeds from leverage. The Trust’s leveraging strategy may not be successful.

Certain types of leverage the Trust may use may result in the Trust being subject to covenants relating to asset coverage and portfolio composition requirements. The Trust 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 Trust. 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 Trust’s portfolio in accordance with its investment objectives and policies if the Trust were to utilize leverage. To the extent permitted, the Board of Trustees of the Trust may modify the Trust’s borrowing policies, including the purposes of borrowings, and the length of time that the Trust may hold portfolio securities purchased with borrowed money. The rights of any lenders to the Trust to receive payments of interest or repayments of principal may be senior to those of the shareholders.

Under the Investment Company Act, the Trust is not permitted to issue senior securities if, immediately after the issuance of such senior securities, the Trust would have an asset coverage ratio (as defined in the Investment

- 21 -

Company Act) of less than 300% with respect to senior securities representing indebtedness or less than 200% with respect to senior securities representing preferred shares. The Investment Company Act also provides that the Trust 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) are not in excess of 5% of the total assets of the Trust.

Effects of Leverage

Assuming that leverage will represent approximately 34.33% of the Trust’s Managed Assets and that the Trust will bear expenses relating to that leverage at an average annual rate of 4.51%, the income generated by the Trust’s portfolio (net of estimated expenses) must exceed 1.55% 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 investments held in the Trust’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 Trust. The table further reflects the use of leverage representing 34.33% of the Trust’s Managed Assets and an assumed annual cost of leverage of 4.51%.


Assumed Portfolio Total Return (Net of Expenses)	(10.00)%	(5.00)%	0%	5.00%	10.00%
Common Share Total Return	(17.59)%	(9.97)%	(2.36)%	5.25%	12.87%

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

Reverse Repurchase Agreements

The Trust may enter into reverse repurchase agreements with the same parties with whom it may enter into repurchase agreements. Under a reverse repurchase agreement, the Trust sells securities to another party and agrees to repurchase them at a particular date and price. The Trust may enter into a reverse repurchase agreement when it is anticipated that the interest income to be earned from the investment of the proceeds of the transaction is greater than the interest expense of the transaction.

The use of reverse repurchase agreements may be regarded as leveraging and, therefore, speculative. Furthermore, reverse repurchase agreements involve the risks that (i) the interest income earned in the investment of the proceeds will be less than the interest expense, (ii) the market value of the securities retained in lieu of sale by the Trust may decline below the price of the securities the Trust has sold but is obligated to repurchase, (iii) the market value of the securities sold will decline below the price at which the Trust is required to repurchase them and (iv) the securities will not be returned to the Trust.

In addition, if the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, such buyer or its trustee or receiver may receive an extension of time to determine whether to enforce the Trust’s obligations to repurchase the securities and the Trust’s use of the proceeds of the reverse repurchase agreement may effectively be restricted pending such decision.

- 22 -

Rule

18f-4

under the Investment Company Act permits the Trust to enter into reverse repurchase agreements and similar financing transactions (e.g., recourse and

non-recourse

tender option bonds, borrowed bonds) notwithstanding the limitation on the issuance of senior securities in Section 18 of the Investment Company Act, provided that the Trust either (i) complies with the 300% asset coverage ratio with respect to all such transactions and any other borrowings in the aggregate, or (ii) treats all such transactions as Derivatives Transactions under Rule

18f-4.

See “—Derivatives—Regulation of Derivatives—Rule

18f-4

under the Investment Company Act” in the SAI. The SEC has also finalized rules that will require certain transactions involving U.S. Treasuries, including reverse repurchase agreements, to be centrally cleared. Compliance with these rules is expected to be required by the middle of 2027. Although the impact of these rules on the Trust is difficult to predict, they may reduce the availability or increase the costs of such transactions and may adversely affect the Trust’s performance.

Additionally, regulations adopted by global prudential regulators require certain bank-regulated counterparties and certain of their affiliates to include in certain financial contracts, including many reverse repurchase agreements, terms that delay or restrict the rights of counterparties, such as the Trust, to terminate such agreements, take foreclosure action, exercise other default rights or restrict transfers of credit support in the event that the counterparty and/or its affiliates are subject to certain types of resolution or insolvency proceedings. It is possible that these requirements, as well as potential additional government regulation and other developments in the market, could adversely affect the Trust’s ability to terminate existing reverse repurchase agreements or to realize amounts to be received under such agreements.

Tender Option Bond Transactions

The Trust currently leverages its assets through the use of TOB Residuals, which are derivative interests in municipal bonds. The TOB Residuals in which the Trust will invest pay interest or income that, in the opinion of counsel to the issuer, is exempt from regular U.S. 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 Trust, 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.

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. The Trust 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 Liquidity Provider (defined below) which allows holders to tender their position at par (plus accrued interest). The Trust, as a holder of TOB Residuals, is paid the residual cash flow from the TOB Trust. The Trust 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 Trust 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 may contribute municipal bonds to a TOB Trust into which the Trust 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 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

- 23 -

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 Trust, as a TOB Residual holder, would be responsible for reimbursement of any payments of principal and interest made by the credit enhancement provider.

The TOB Residuals held by the Trust generally provide the Trust 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 Trust may withdraw a corresponding share of the municipal bonds from the TOB Trust. This transaction, in effect, creates exposure for the Trust to the entire return of the municipal bonds in the TOB Trust, with a net cash investment by the Trust 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 Trust (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 Trust 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.

The TOB Trust may be collapsed without the consent of the Trust upon the occurrence of tender option termination events (“TOTEs”) and mandatory termination events (“MTEs”), as defined in the TOB Trust agreements. TOTEs include the bankruptcy or default of the issuer of the municipal bonds held in the TOB Trust, a substantial downgrade in the credit quality of the issuer of the municipal bonds held in the TOB Trust, failure of any scheduled payment of principal or interest on the municipal bonds, and a judgment or ruling that interest on the municipal bonds is subject to U.S. federal income taxation. MTEs may include, among other things, a failed remarketing of the TOB Floaters, the inability of the TOB Trust to obtain renewal of the liquidity support agreement, and a substantial decline in the market value of the municipal bonds held in the TOB Trust. Upon the occurrence of a TOTE or an MTE, 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 Liquidity Provider (defined below). In the case of an MTE, after the payment of fees, the holders of the TOB Floaters would be paid senior to the TOB Residual holders (i.e., the Trust). In contrast, in the case of a TOTE, after payment of fees, the holders of the TOB Floaters and the TOB Residual holders would be paid pro rata in proportion to the respective face values of their certificates.

The Trust may invest in a TOB Trust on either a

non-recourse

or recourse basis. TOB Trusts are typically supported by a liquidity facility provided by a third-party bank of other financial institution (the “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 TOTE described above). Depending on the structure of the TOB Trust, the Liquidity Provider may purchase the tendered TOB Floaters, or the TOB Trust may draw upon a loan from the Liquidity Provider to purchase the tendered TOB Floaters.

When the Trust 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 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 amount owed under the liquidity facility over the liquidation proceeds (the “Liquidation Shortfall”). If the Trust invests in a TOB Trust on a recourse basis, it will typically enter into a reimbursement agreement with the Liquidity Provider pursuant to which the Trust is required to reimburse the Liquidity Provider the amount of any Liquidation Shortfall. As a result, if the Trust invests in a recourse TOB Trust, the Trust 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 Trust that are deposited into a TOB Trust are investments of the Trust and are presented on the Trust’s Schedule of Investments and outstanding TOB Floaters issued by a TOB

- 24 -

Trust are presented as liabilities in the Trust’s Statement of Assets and Liabilities. Interest income from the underlying Municipal Bonds is recorded by the Trust 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 Trust. In addition, under accounting rules, loans made to a TOB Trust sponsored by the Trust may be presented as loans of the Trust in the Trust’s financial statements even if there is no recourse to the Trust’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 risk associated with TOB Floaters, however, may be increased in the current market environment as a result of recent downgrades to the credit ratings, and thus the perceived reliability and creditworthiness, of many major financial institutions, some of which sponsor and/or provide liquidity support to TOB Trusts. This in turn may reduce the desirability of TOB Floaters as investments, which could impair the viability or availability of TOB Trusts.

Rule

18f-4

under the Investment Company Act permits the Trust to enter into TOB Trust transactions, reverse repurchase agreements and similar financing transactions (e.g., borrowed funds) notwithstanding the limitation on the issuance of senior securities in Section 18 of the Investment Company Act, provided that the Trust either (i) complies with the 300% asset coverage ratio with respect to such transactions and any other borrowings in the aggregate, or (ii) treats such transactions as derivatives transactions under Rule

18f-4.

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

Derivatives—Rule18f-4

Under the Investment Company Act” in the SAI.

Credit Facility

The Trust may borrow through a credit facility. If the Trust enters into a credit facility, the Trust may be required to prepay outstanding amounts or incur a penalty rate of interest upon the occurrence of certain events of default. The Trust would also likely have to indemnify the lenders under the credit facility against liabilities they may incur in connection therewith. In addition, the Trust expects that any credit facility would contain covenants that, among other things, likely would limit the Trust’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 Trust 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 Trust expects that any credit facility would have customary covenant, negative covenant and default provisions. There can be no assurance that the Trust 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.

Preferred Shares

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

- 25 -

The Trust 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 Trust expects that it would pay a fee to the provider of this liquidity feature, which would be borne by common shareholders of the Trust. The terms of such liquidity feature could require the Trust to redeem preferred shares still owned by the liquidity provider following a certain period of continuous, unsuccessful remarketing, which may adversely impact the Trust.

If preferred shares are issued, the Trust 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 Trust and may also prohibit dividends and other distributions on the common shares in such circumstances. In order to meet redemption requirements, the Trust may have to liquidate portfolio securities. Such liquidations and redemptions would cause the Trust to incur related transaction costs and could result in capital losses to the Trust. Prohibitions on dividends and other distributions on the common shares could impair the Trust’s ability to qualify as a RIC under the Code. If the Trust has preferred shares outstanding, two of the Trustees will be elected by the holders of preferred shares voting separately as a class. The remaining Trustees will be elected by holders of common shares and preferred shares voting together as a single class. In the event the Trust failed to pay dividends on preferred shares for two years, holders of preferred shares would be entitled to elect a majority of the Trustees.

If the Trust issues preferred shares, the Trust 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 Trust. These guidelines are expected to impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Trust by the Investment Company Act. It is not anticipated that these covenants or guidelines would impede the Advisor from managing the Trust’s portfolio in accordance with the Trust’s investment objective and policies.

Derivatives

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

Under Rule

18f-4

under the Investment Company Act, among other things, the Trust must either use derivatives in a limited manner or comply with an outer limit on fund leverage risk based on

value-at-risk.

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

18f-4

Under the Investment Company Act” in the SAI.

Temporary Borrowings

The Trust 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 Trust securities.

RISKS

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

General Risks

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

Other Risks

Risk Associated with Recent Market Events

In 2022 and 2023, the Federal Reserve raised interest rates eleven times as part of its efforts to address rising inflation. Certain foreign central banks similarly tightened monetary policy during this period. Beginning in September 2024, the Federal Reserve began lowering interest rates, cutting the federal funds rate six times through December 2025. The Federal Reserve held the federal funds rate steady in the first quarter of 2026, though further rate changes may occur depending on economic conditions, including the pace of inflation and the state of the labor market. It is difficult to accurately predict the pace at which interest rates might change, the timing, frequency or magnitude of any such changes in interest rates, or when such changes might stop or again reverse course. Additionally, various economic and political factors, including trade policy, fiscal policy and geopolitical developments, could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected changes in interest rates could lead to significant market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility, reduce liquidity across various markets or decrease confidence in the markets, which could negatively affect the value of debt instruments held by the Trust and result in a negative impact on the Trust’s performance.

Recent policy initiatives undertaken by the U.S. government have the potential to impact international relations, trade agreements and the overall regulatory environment in ways that could create uncertainty and instability in domestic and global markets, and could adversely affect the investment performance of the Trust. In particular, actions taken by the U.S. government in respect of international trade relations could lead to trade wars, increased costs for imported goods, disruptions in supply chains, reduced foreign investment, and instability in regions where the Trust invests. Political and diplomatic events within the United States, including a contentious domestic political environment, changes in political party control of one or more branches of the U.S. government, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, the threat of a U.S. government shutdown, and disagreements over, or threats not to increase, the U.S. government’s borrowing limit (or “debt ceiling”), as well as political and diplomatic events abroad, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. A downgrade of the ratings of U.S. government debt obligations, or concerns about the U.S. government’s credit quality in general, could have a substantial negative effect on the U.S. and global economies. For example, concerns about the U.S. government’s credit quality may cause increased volatility in the stock and bond markets, higher interest rates, reduced prices and liquidity of U.S. Treasury securities, and/or increased costs of various kinds of debt. Moreover, although the U.S. government has honored its credit obligations, there remains a possibility that the United States could default on its obligations. The consequences of such an unprecedented event are impossible to predict, but it is likely that a default by the United States would be highly disruptive to the U.S. and global securities markets and could significantly impair the value of the Trust’s investments.

In recent years, some countries, including the United States, have adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, inflationary pressures, changes to some major international trade agreements, risks associated with the trade agreements between countries and regions, including the U.S. and other foreign nations, political or economic dysfunction within some countries or regions,

including the U.S., and dramatic changes in commodity and currency prices could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time.

Reference Rate Replacement Risk

The London Interbank Offered Rate (“LIBOR”) had historically been used extensively in the U.S. and globally as a “benchmark” or “reference rate” for various commercial and financial contracts, including corporate and municipal bonds, bank loans, asset-backed and mortgage-related securities, interest rate swaps and other derivatives. Instruments in which the Trust invests may have historically paid interest at floating rates based on LIBOR or may have been subject to interest caps or floors based on LIBOR. The Trust and issuers of instruments in which the Trust invests may have also historically obtained financing at floating rates based on LIBOR. In connection with the global transition away from LIBOR led by regulators and market participants as a result of benchmark reforms, LIBOR was last published on a representative basis at the end of June 2023. Alternative reference rates to LIBOR have been established in most major currencies and markets in these alternative rates are continuing to develop (e.g., the Secured Overnight Financing Rate (“SOFR”) for

USD-LIBOR).

While the transition from LIBOR has gone relatively smoothly, residual risks associated with the transition may remain that may impact markets or particular investments and, as such, the full impact of the transition on the Trust or the financial instruments in which the Trust invests cannot yet be fully determined.

SOFR is intended to be a broad measure of the cost of borrowing funds overnight in transactions that are collateralized by U.S. Treasury securities. SOFR is calculated based on transaction-level repo data collected from various sources. For each trading day, SOFR is calculated as a volume-weighted median rate derived from such data. Because SOFR is a financing rate based on overnight secured funding transactions, it differs fundamentally from LIBOR. LIBOR is intended to be an unsecured rate that represents interbank funding costs for different short-term maturities or tenors. It is a forward-looking rate reflecting expectations regarding interest rates for the applicable tenor. Thus, LIBOR is intended to be sensitive, in certain respects, to bank credit risk and to term interest rate risk. In contrast, SOFR is a secured overnight rate reflecting the credit of U.S. Treasury securities as collateral. Thus, it is largely insensitive to credit-risk considerations and to short-term interest rate risks. SOFR is a transaction-based rate, and it has been more volatile than other benchmark or market rates, such as three-month LIBOR, during certain periods. For these reasons, among others, there is no assurance that SOFR, or rates derived from SOFR, will perform in the same or similar way as LIBOR would have performed at any time, and there is no assurance that SOFR-based rates will be a suitable substitute for LIBOR. SOFR has a relatively limited history, having been first published in April 2018. The future performance of SOFR, and SOFR-based reference rates, cannot be predicted based on SOFR’s history or otherwise. Levels of SOFR in the future may bear little or no relation to historical levels of SOFR, LIBOR or other rates. There can also be no assurance that SOFR will not be discontinued or fundamentally altered in a manner that is materially adverse to the interests of the Trust.

In addition, interest rates or other types of rates and indices which are classified as “benchmarks” have been the subject of ongoing national and international regulatory reform, including under the European Union (“EU”) regulation on indices used as benchmarks in financial instruments and financial contracts (known as the “Benchmarks Regulation”). The Benchmarks Regulation has been enacted into United Kingdom (“UK”) law by virtue of the EU (Withdrawal) Act 2018 (as amended), subject to amendments made by the Benchmarks (Amendment and Transitional Provision) (EU Exit) Regulations 2019 (SI 2019/657) and other statutory instruments. Following the implementation of these reforms, the manner of administration of benchmarks has changed and may further change in the future, with the result that relevant benchmarks may perform differently than in the past, the use of benchmarks that are not compliant with the new standards by certain supervised entities may be restricted, and certain benchmarks may be eliminated entirely. Such changes could cause increased market volatility and disruptions in liquidity for instruments that rely on or are impacted by such benchmarks. Additionally, there could be other consequences which cannot be predicted.

- 28 -

Market Disruption and Geopolitical Risk

Investments by the Trust are materially affected by conditions in the global financial markets and economic and political conditions throughout the world, such as interest rates, the availability and cost of credit, inflation rates, economic uncertainty, changes in laws, trade policies, commodity prices, tariffs, currency exchange rates and controls and national and international political circumstances (including wars and other forms of conflict, terrorist acts, and security operations) and catastrophic events such as fires, floods, earthquakes, tornados, hurricanes and pandemics could materially affect the Trust’s investments to the extent it materially affects global economies or global financial markets.

Additionally, the occurrence of events similar to those in recent years, such as localized wars, instability, new and ongoing epidemics and pandemics of infectious diseases and other global health events, natural/environmental disasters, terrorist attacks in the United States and around the world, social and political discord, debt crises, sovereign debt downgrades, increasingly strained relations between the United States and a number of foreign countries, new and continued political unrest in various countries, the exit or potential exit of one or more countries from the European Union, continued changes in the balance of political power among and within the branches of the U.S. government, government shutdowns and other factors, may result in market volatility, may have long term effects on the United States and worldwide financial markets, and may cause further economic uncertainties in the United States and worldwide and could have a significant adverse impact on the value and risk profile of the Trust’s portfolio. These factors are outside of the Trust’s control and may affect the level and volatility of securities prices and the liquidity and value of the Trust’s portfolio investments, and the Trust may not be able to successfully manage its exposure to these conditions, which may result in substantial losses to shareholders.

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

In recent years, the U.S. government has indicated its intent to alter its approach to international trade policy and in some cases to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements and treaties with foreign countries, and has made proposals and taken actions related thereto, including the imposition of tariffs on imported goods. Tariffs on imported goods could further increase costs, decrease margins, reduce the competitiveness of products and services offered by current and future portfolio companies and adversely affect the revenues and profitability of portfolio companies whose businesses rely on goods imported from such impacted jurisdictions. More generally, 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 a foreign country’s export industry, which could have a negative impact on the Trust’s performance. The U.S. government has imposed, and may in the future further increase, tariffs on certain foreign goods imported into the U.S., including from China, Canada and Mexico, such as steel and aluminum. Some foreign governments, including China, have instituted retaliatory tariffs on certain U.S. goods. 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

- 29 -

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

. Increased trade tensions could have a material adverse effect on the global economy. The Trust and its portfolio investments could be materially and adversely affected.

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

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

Regulation and Government Intervention Risk

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

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

closed-end

investment company such as the Trust and a large financial institution, a court may similarly seek to strictly interpret terms and legal rights in favor of retail investors.

The Trust 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 Trust and its ability to achieve its investment objectives.

Investment Company Act Regulations

The Trust is a registered

closed-end

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

Regulation as a “Commodity Pool”

- 30 -

Failures of Futures Commission Merchants and Clearing Organizations Risk

The Trust 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 Trust 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 Trust’s FCM. In addition, the assets of the Trust posted as margin against both swaps and futures contracts may not be fully protected in the event of the FCM’s bankruptcy.

Legal, Tax and Regulatory Risks

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

To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Trust 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 Trust 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 Trust’s current and accumulated earnings and profits.

The current presidential administration has called for significant changes to U.S. fiscal, tax, trade, healthcare, immigration, foreign, and government regulatory policy. In this regard, there is significant uncertainty with respect to legislation, regulation and government policy at the federal level, as well as the state and local levels. Recent events have created a climate of heightened uncertainty and introduced new and

difficult-to-quantify

macroeconomic and political risks with potentially

far-reaching

implications. There has been a corresponding meaningful increase in the uncertainty surrounding interest rates, inflation, foreign exchange rates, trade volumes and fiscal and monetary policy. To the extent the U.S. Congress or the current presidential administration implements changes to U.S. policy, those changes may impact, among other things, the U.S. and global economy, international trade and relations, unemployment, immigration, corporate taxes, healthcare, the U.S. regulatory environment, inflation and other areas. Although the Trust cannot predict the impact, if any, of these changes to the Trust’s business, they could adversely affect the Trust’s business, financial condition, operating results and cash flows. Until the Trust knows what policy changes are made and how those changes impact the Trust’s business and the business of the Trust’s competitors over the long term, the Trust will not know if, overall, the Trust will benefit from them or be negatively affected by them.

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

Potential Conflicts of Interest of the Advisor and Others

The investment activities of the Advisor and its affiliates (including BlackRock, Inc. and its subsidiaries (collectively, the “Affiliates”)), and their respective directors, officers or employees, in managing their own

- 31 -

accounts and other accounts, may present conflicts of interest that could disadvantage the Trust and its shareholders. The Advisor and its Affiliates may engage in proprietary trading and advise accounts and other funds that have investment objectives similar to those of the Trust and/or that engage in and compete for transactions in the same or similar types of securities, currencies and other assets as are held by the Trust. Subject to the requirements of the Investment Company Act, the Advisor and its Affiliates intend to engage in such activities and may receive compensation from third parties for their services. Neither the Advisor nor any Affiliate is under any obligation to share any investment opportunity, idea or strategy with the Trust. As a result, an Affiliate may compete with the Trust for appropriate investment opportunities. The results of the Trust’s investment activities, therefore, may differ from those of an Affiliate and of another account managed by an Affiliate. It is possible that the Trust could sustain losses during periods in which one or more Affiliates and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible. The Advisor has adopted policies and procedures designed to address potential conflicts of interest. For additional information about potential conflicts of interest and the way in which BlackRock addresses such conflicts, please see “Conflicts of Interest” and “Management of the Trust—Portfolio Management—Potential Material Conflicts of Interest” in the SAI.

Defensive Investing Risk

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

Decision-Making Authority Risk

Investors have no authority to make decisions or to exercise business discretion on behalf of the Trust, except as set forth in the Trust’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 Trust’s investment activities to the Advisor, subject to oversight by the Board.

Management Risk

The Trust 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 Trust, but there can be no guarantee that these will produce the desired results. The Trust may be subject to a relatively high level of management risk because the Trust may invest in derivative instruments, which may be highly specialized instruments that require investment techniques and risk analyses different from those associated with equities and bonds.

Valuation Risk

The Trust is subject to valuation risk, which is the risk that one or more of the securities in which the Trust invests are valued at prices that the Trust 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 instruments 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

- 32 -

may introduce significant variances in the ultimate valuation of the Trust’s investments. Technological issues and/or errors by pricing services or other third-party service providers may also impact the Trust’s ability to value its investments and the calculation of the Trust’s NAV.

When market quotations are not readily available or are believed by the Advisor to be unreliable, the Advisor will fair value the Trust’s investments in accordance with its policies and procedures. Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Trust is the amount the Trust might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s length transaction. Fair value pricing may require determinations that are inherently subjective and inexact about the value of a security or other asset. As a result, there can be no assurance that fair value priced assets will not result in future adjustments to the prices of securities or other assets, or that fair value pricing will reflect a price that the Trust 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 Trust’s NAV could be adversely affected if the Trust’s determinations regarding the fair value of the Trust’s investments were materially higher than the values that the Trust 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 Trust, the value at which its investments can be liquidated may differ, sometimes significantly, from the interim valuations obtained by the Trust. In addition, the timing of liquidations may also affect the values obtained on liquidation. Securities held by the Trust may routinely trade with

bid-offer

spreads that may be significant. There can be no guarantee that the Trust’s investments could ultimately be realized at the Trust’s valuation of such investments. In addition, the Trust’s compliance with the asset diversification tests applicable to regulated investment companies depends on the fair market values of the Trust’s assets, and, accordingly, a challenge to the valuations ascribed by the Trust could affect its ability to comply with those tests or require it to pay penalty taxes in order to cure a violation thereof.

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

Reliance on the Advisor Risk

The Trust 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 Trust 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 Trust. The loss of, or changes in, the Advisor’s personnel could have a negative effect on the performance or the continued operation of the Trust. For additional information on the Advisor and BlackRock, see “Management of the Trust—Investment Advisor.”

Reliance on Service Providers Risk

The Trust must rely upon the performance of service providers to perform certain functions, which may include functions that are integral to the Trust’s operations and financial performance. Failure by any service provider to carry out its obligations to the Trust in accordance with the terms of its appointment, to exercise due care and skill or to perform its obligations to the Trust at all as a result of insolvency, bankruptcy or other causes could have a material adverse effect on the Trust’s performance and returns to shareholders. The termination of the Trust’s relationship with any service provider, or any delay in appointing a replacement for such service

- 33 -

provider, could materially disrupt the business of the Trust and could have a material adverse effect on the Trust’s performance and returns to shareholders.

Information Technology Systems Risk

The Trust 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 Trust. 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 Trust. Further, failure of the back-office functions of the Advisor to process trades in a timely fashion could prejudice the investment performance of the Trust.

Operational and Technology Risks

The Trust and the entities with which it interacts directly or indirectly are susceptible to operational and technology risks, including those related to human errors, processing errors, communication errors, systems failures, cybersecurity incidents, and the use of artificial intelligence and machine learning, which may result in losses for the Trust and its shareholders or impair the Trust’s operations. These entities include, but are not limited to, the Trust’s adviser, administrator, distributor, other service providers (e.g., index and benchmark providers, accountants, custodians, and transfer agents), financial intermediaries, counterparties, market makers, listing exchanges, other financial market operators, and governmental authorities, as applicable. Operational and technology risks for the issuers in which the Trust invests could also result in material adverse consequences for such issuers and may cause the Trust’s investments in such issuers to lose value. The Trust may incur substantial costs in order to mitigate operational and technology risks.

Cybersecurity incidents can result from deliberate attacks or unintentional events against an issuer in which the Trust invests, the Trust or any of its service providers. They include, but are not limited to, gaining unauthorized access to systems, misappropriating assets or sensitive information, corrupting or destroying data, and causing operational disruption. Geopolitical tension may increase the scale and sophistication of deliberate attacks, particularly those from nation states or from entities with nation state backing. Cybersecurity incidents may result in any of the following: financial losses; interference with the Trust’s ability to calculate its NAV; disclosure of confidential information; impediments to trading; submission of erroneous trades by the Trust or erroneous subscription or redemption orders; the inability of the Trust or its service providers to transact business; violations of applicable privacy and other laws; regulatory fines; penalties; reputational damage; reimbursement or other compensation costs; and other legal and compliance expenses. Furthermore, cybersecurity incidents may render records of the Trust, including records relating to its assets and transactions, shareholder ownership of Trust shares, and other data integral to the Trust’s functioning, inaccessible, inaccurate or incomplete. Power outages, natural disasters, equipment malfunctions and processing errors that threaten information and technology systems relied upon by the Trust or its service providers, as well as market events that occur at a pace that overloads these systems, may also disrupt business operations or impact critical data. Recent advances in artificial intelligence and machine learning technology pose risks to the Trust and its portfolio investments. These advancements could harm the Trust and its portfolio investments by reducing the demand for both the technology and software offerings of the Trust’s portfolio investments. Additionally, these advancements could significantly disrupt the Trust’s portfolio investments and subject them to increased competition, which could have a material adverse effect on business, financial condition, and results of operations. Artificial intelligence and machine learning technology advancements, including efficiency improvements, without related increases in the adoption and development of such technologies, could also negatively impact demand for, and the valuation of, digital infrastructure assets.

- 34 -

use artificial intelligence and machine learning technology in their business activities. The Trust and its service providers may not be in a position to control the use of artificial intelligence and machine learning technology in third-party products or services.

Use of artificial intelligence and machine learning technology could include the input of confidential information in contravention of applicable policies, contractual or other obligations or restrictions, resulting in such confidential information becoming accessible by other third-party artificial intelligence and machine learning technology applications and users.

Independent of its context of use, artificial intelligence and machine learning technology is generally highly reliant on the collection and analysis of large amounts of data, may incorporate biased or inaccurate data, and it is not possible or practicable to incorporate all relevant data into the models that artificial intelligence and machine learning technology utilizes to operate. Certain data in such models will inevitably contain a degree of inaccuracy and error, or could otherwise be inadequate or flawed, which would be likely to degrade the effectiveness of artificial intelligence and machine learning technology. The output or results of any such AI technologies may therefore be incomplete, erroneous, distorted or misleading. Further, AI tools may lack transparency as to how data is utilized and how outputs are generated. AI technologies may also allow the unintended introduction of vulnerabilities into infrastructures and applications. To the extent that the Trust or its portfolio investments are exposed to the risks of artificial intelligence and machine learning technology use, any such inaccuracies or errors could have adverse impacts on the Trust or its investments.

Regulations related to artificial intelligence and machine learning technology could also impose certain obligations and costs related to monitoring and compliance. For example, in April 2023, the Federal Trade Commission, U.S. Department of Justice, Consumer Financial Protection Bureau, and U.S. Equal Employment Opportunity Commission released a joint statement on artificial intelligence demonstrating interest in monitoring the development and use of automated systems and enforcement of their respective laws and regulations. In October 2023, an executive order established new standards for AI safety and security. In addition to the U.S. regulatory framework, in 2024, the EU adopted the Artificial Intelligence Act, which applies to certain artificial intelligence and machine learning technology and the data used to train, test, and deploy them, which may create additional compliance burdens, higher administrative costs, and significant penalties should the Trust, the adviser, or the Trust’s portfolio investments fail to comply.

Artificial intelligence and machine learning technology and its applications, including in the investment and financial sectors, continue to develop rapidly, and it is impossible to predict the future risks that may arise from such developments. The full extent of current or future risks related thereto is not possible to predict, and the Trust may not be able to anticipate, prevent, mitigate, or remediate all of the potential risks, challenges, or impacts of such changes.

While the Trust’s service providers are required to have appropriate operational, information security and cybersecurity risk management policies and procedures, their methods of risk management may differ from those of the Trust in the setting of priorities, the personnel and resources available or the effectiveness of relevant controls. The Trust and its adviser seek to reduce these risks through controls, procedures and oversight, including establishing business continuity plans and risk management systems. However, there are inherent limitations in such plans and systems, including the possibility that certain risks that may affect the Trust have not been identified or may emerge in the future; that such plans and systems may not completely eliminate the occurrence or mitigate the effects of operational or information security disruptions or failures or of cybersecurity incidents; or that prevention and remediation efforts will not be successful or that incidents will go undetected. The Trust cannot control the systems, information security or other cybersecurity of the issuers in which it invests or its service providers, counterparties, and other third parties whose activities affect the Trust.

Lastly, the regulatory climate governing cybersecurity and data protection is developing quickly and may vary considerably across jurisdictions. Regulators continue to develop new rules and standards related to cybersecurity

- 35 -

and data protection. Compliance with evolving regulations can be demanding and costly, requiring substantial resources to monitor and implement required changes.

Misconduct of Employees and of Service Providers Risk

Misconduct or misrepresentations by employees of the Advisor or the Trust’s service providers could cause significant losses to the Trust. Employee misconduct may include binding the Trust 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 Trust’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 Trust’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.

Portfolio Turnover Risk

The Trust’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 Trust. A higher portfolio turnover rate results in correspondingly greater brokerage commissions and other transactional expenses that are borne by the Trust. High portfolio turnover may result in an increased realization of net short-term capital gains by the Trust which, when distributed to common shareholders, will be taxable as ordinary income. Additionally, in a declining market, portfolio turnover may create realized capital losses.

Anti-Takeover Provisions Risk

The Trust’s Agreement and Declaration of Trust and Bylaws include provisions that could limit the ability of other entities or persons to acquire control of the Trust or convert the Trust 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 Trust. See “Certain Provisions in the Agreement and Declaration of Trust and Bylaws.”

HOW THE TRUST MANAGES RISK

Investment Limitations

The Trust 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 Objectives 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 Trust may take certain actions if short-term interest rates increase or market conditions otherwise change (or the Trust anticipates such an increase or change) and any leverage the Trust may have outstanding begins (or is expected) to adversely affect common shareholders. In order to attempt to offset such a negative impact of any

- 36 -

outstanding leverage on common shareholders, the Trust 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. 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 Trust 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 Trust already has outstanding leverage, would be beneficial, the Trust 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.

Strategic Transactions

The Trust 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 Trust’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.

MANAGEMENT OF THE TRUST

Trustees and Officers

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

Investment Advisor

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

BlackRock is a leading publicly traded investment management firm with $13.9 trillion of assets under management as of March 31, 2026. BlackRock provides a broad range of investment and technology services to institutional and retail clients worldwide. BlackRock has over 35 years of experience managing closed-end products and, as of March 31, 2026, advised a registered closed-end family of 36 exchange-listed funds with approximately $44 billion in assets. BlackRock is independent in ownership and governance, with no single majority shareholder and a majority of independent directors.

Investment Philosophy

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.

The Advisor uses a relative value strategy that evaluates the

trade-off

between risk and return to seek to achieve the Trust’s investment objectives. 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.

Investment Management Agreement

Pursuant to an investment management agreement between the Advisor and the Trust (the “Investment Management Agreement”), the Trust 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 Trust’s Managed Assets. “Managed Assets” means the total assets of the Trust (including any assets attributable to money borrowed for investment purposes) minus the sum of the Trust’s accrued liabilities (other than money borrowed for investment purposes).

A discussion regarding the basis for the approval of the Investment Management Agreement by the Board is available in the Trust’s semi-annual report to shareholders for the period ended June 30, 2025.

- 38 -

Except as otherwise described in this Prospectus, the Trust pays, in addition to the fees paid to the Advisor, all other costs and expenses of its operations, including compensation of its Trustees (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.

Administration and Accounting Services

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

Custodian and Transfer Agent

The custodian of the assets of the Trust is State Street Bank and Trust Company, whose principal business address is One Congress Street, Boston, Massachusetts 02114. The custodian is responsible for, among other things, receipt of and disbursement of funds from the Trust’s accounts, establishment of segregated accounts as necessary, and transfer, exchange and delivery of Trust portfolio securities.

Computershare Trust Company, N.A., whose principal business address is 150 Royall Street, Canton, Massachusetts 02021, serves as the Trust’s transfer agent with respect to the common shares.

Independent Registered Public Accounting Firm

Deloitte & Touche LLP, whose principal business address is 115 Federal Street, Boston, Massachusetts 02110, is the independent registered public accounting firm of the Trust and is expected to render an opinion annually on the financial statements of the Trust.

NET ASSET VALUE

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

- 39 -

NYSE on each business day on which the NYSE is open for trading. The Trust calculates NAV per common share by subtracting the Trust’s liabilities (including accrued expenses, dividends payable and any borrowings of the Trust), and the liquidation value of any outstanding preferred shares of the Trust from the Trust’s total assets (the value of the securities the Trust 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 Trust outstanding.

Valuation of securities held by the Trust is as follows:

Equity Investments.

Equity securities traded on a recognized securities exchange (e.g., NYSE), on separate trading boards of a securities exchange or through a market system that provides contemporaneous transaction pricing information (each, an “Exchange”) are valued using information obtained 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 Trust on a day on which the Trust 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 Trust 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 Trust 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 (as defined below).

Fixed-Income Investments.

Fixed-income securities are generally valued using bid prices provided by dealers or prices (including evaluated prices) supplied by the Trust’s approved independent third-party pricing services, each in accordance with the Advisor’s policies and procedures (the “Valuation Procedures”). The pricing services may use 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/or other factors and assumptions. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but the Trust may hold or transact in such securities in smaller, odd lot sizes. Odd lots of securities in certain asset classes may trade at lower prices than institutional round lots, and the value ultimately realized when the securities are sold could differ from the prices used by the Trust. The amortized cost method of valuation may be used with respect to debt obligations with 60 days or less remaining to maturity unless such method does not represent fair value. 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 issuer, 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 (except ETF options, equity index options or those that are customized) 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 Trust on a day on which the Trust 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 Trust 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. Customized exchange-traded equity options, ETF options, equity index options and 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

- 40 -

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.

Underlying Funds.

Shares of underlying

open-end

funds (including money market funds) are valued at NAV. Shares of underlying exchange-traded

closed-end

funds and ETFs will be valued at their most recent closing price.

General Valuation Information.

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

In determining the market value of portfolio investments, the Trust may employ independent third party pricing services, which may use, without limitation, evaluated pricing methods that take into consideration market indexes, matrices, yield curves and other specified inputs and assumptions. This may result in the assets being valued at a price different from the price that would have been determined had the evaluated pricing method not been used. The price the Trust could receive upon the sale of any particular portfolio investment may differ from the Trust’s valuation of the investment, particularly for assets 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 Trust, and the Trust could realize a greater than expected loss or lesser than expected gain upon the sale of the investment. The Trust’s ability to value its investments may also be impacted by technological issues and/or errors by pricing services or other third party service providers.

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 approved by the Advisor, the Trust’s valuation designee, as reflecting fair value. All other assets and liabilities (including securities for which market quotations are not readily available) held by the Trust (including restricted securities and private market investments, as applicable) are valued at fair value as determined in good faith by the Advisor pursuant to the Valuation Procedures. Any assets and liabilities which are denominated in a foreign currency are translated into U.S. dollars at the prevailing market rates.

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

Fair Value.

When market quotations are not readily available or are believed by the Advisor to be unreliable, the Trust’s investments are valued at fair value (“Fair Value Assets”). Fair Value Assets are valued by the Advisor in accordance with the Valuation Procedures. Pursuant to Rule

2a-5

under the Investment Company Act, the Board has designated the Advisor as the valuation designee for the Trust. The Advisor may reasonably conclude that a market quotation is not readily available or is unreliable if, among other things, 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), or 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 reasonable business judgment, that an event that has occurred after the close of trading for an asset or liability but prior to or at the time of pricing the Trust’s assets or liabilities, is likely to cause a material change to the last exchange closing price or closing market price of one or

- 41 -

more assets held by, or liabilities of, the Trust. On any day the NYSE is open and a foreign market or 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 assets, 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 assets in one or more

non-U.S.

markets following the close of the local markets to the prices that might have prevailed as of the Trust’s pricing time.

The Advisor’s Rule

2a-5

Committee is responsible for reviewing and approving methodologies by investment type and significant inputs used in the fair valuation of Trust assets or liabilities. In addition, the Trust’s accounting agent assists the Advisor by periodically endeavoring to confirm the prices it receives from all third party pricing services, index providers and broker-dealers. The Advisor regularly evaluates the values assigned to the securities and other assets and liabilities of the Trust.

When determining the price for a Fair Value Asset, the Advisor will seek to determine the price that the Trust might reasonably expect to receive from the current sale of that asset or liability in an

arm’s-length

transaction on the date on which the asset or liability is being valued, and does not seek to determine the price the Trust 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 will be based upon all available factors that the Advisor 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. When determining the fair value of an investment, one or more fair value methodologies may be used (depending on certain factors, including the asset type). For example, the investment may be initially priced based on the original cost of the investment or, alternatively, using proprietary or third-party models that may rely upon one or more unobservable inputs. Prices of actual, executed or historical transactions in the relevant investment (or comparable instruments) or, where appropriate, an appraisal by a third-party experienced in the valuation of similar instruments, may also be used as a basis for establishing the fair value of an investment.

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 Trust’s NAV. As a result, the Trust’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 Trust’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 funds and various assets in which they invest are evolving. Such changes may adversely affect the Trust. 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. This may in turn increase the costs associated with selling assets or affect their liquidity due to the Trust’s inability to obtain a third-party determination of fair market value.

DISTRIBUTIONS

The Trust intends to make regular monthly cash distributions of all or a portion of its net investment income to holders of the Trust’s common shareholders. The Trust will pay common shareholders at least annually all or substantially all of its investment company taxable income. The Investment Company Act generally limits the Trust to one capital gain distribution per year, subject to certain exceptions, including as discussed below in connection with the Distribution Plan.

The Trust has, with the approval of the Board, adopted a managed distribution plan, consistent with its investment objectives and policies, to support a level distribution of income, capital gains and/or return of capital (the “Distribution Plan”). The Trust is currently not relying on any exemptive relief from Section 19(b) of the Investment Company Act. Under the Distribution Plan, the Trust will distribute all available investment income, including current gains, to its shareholders as required by the Code. If sufficient income (inclusive of net investment income and short-term capital gains) is not earned on a monthly basis, the Trust will distribute long-term capital gains and/or return of capital to shareholders in order to maintain a level distribution. A return of capital distribution may involve a return of the shareholder’s original investment. Though not currently taxable, such a distribution may lower a shareholder’s basis in the Trust, thus potentially subjecting the shareholder to future tax consequences in connection with the sale of Trust shares, even if sold at a loss to the shareholder’s original investment. Each monthly distribution to shareholders is expected to be at the fixed amount established by the Board; however, the Trust may make additional distributions from time to time, including additional capital gain distributions at the end of the taxable year, if required to meet requirements imposed by the Code and/or the Investment Company Act. Shareholders should not draw any conclusions about the Trust’s investment performance from the amount of these distributions or from the terms of the Distribution Plan. The Trust’s total return performance on NAV will be presented in its financial highlights table, which will be available in the Trust’s shareholder reports, every six months.

The Board may amend, suspend or terminate the Distribution Plan without prior notice if it deems such actions to be in the best interests of the Trust or its shareholders. The suspension or termination of the Distribution Plan could have the effect of creating a trading discount (if the Trust’s stock is trading at or above NAV) or widening an existing trading discount. The Trust is subject to risks that could have an adverse impact on its ability to maintain level distributions. Examples of potential risks include, but are not limited to, economic downturns impacting the markets, decreased market volatility, companies suspending or decreasing corporate dividend distributions and changes in the Code. Please see “Risks” for a more complete description of the Trust’s risks.

The tax treatment and characterization of the Trust’s distributions may vary significantly from time to time because of the varied nature of the Trust’s investments. The ultimate tax characterization of the Trust’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 Trust may make total distributions during a fiscal year in an amount that exceeds the Trust’s earnings and profits for U.S. federal income tax purposes. In such situations, the amount by which the Trust’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 Trust’s income, including the asset mix, the average maturity of the Trust’s portfolio, the amount of leverage utilized by the Trust and the Trust’s use of hedging. To permit the Trust to maintain more stable monthly distributions and to the extent consistent with the distribution requirements imposed on regulated investment companies by the Code, the Trust 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 Trust for any particular month may be more or less than the amount actually earned by the Trust during that month. Undistributed earnings will increase the Trust’s NAV and, correspondingly, distributions from undistributed earnings and from capital, if any, will reduce the Trust’s NAV. The Trust intends to distribute any long-term capital gains not distributed under the Distribution Plan annually.

- 43 -

Under normal market conditions, the Advisor seeks to manage the Trust in a manner such that the Trust’s distributions are reflective of the Trust’s current and projected earnings levels. The distribution level of the Trust is subject to change based upon a number of factors, including the current and projected level of the Trust’s earnings, and may fluctuate over time.

Shareholders will automatically have all dividends and distributions reinvested in common shares of the Trust issued by the Trust or purchased in the open market in accordance with the Trust’s dividend reinvestment plan unless an election is made to receive cash. See “Dividend Reinvestment Plan.”

Please refer to the section of the Trust’s most recent annual report on Form

N-CSR

entitled “Automatic Dividend Reinvestment Plan,” which is incorporated by reference herein, for a discussion of the Trust’s dividend reinvestment plan.

RIGHTS OFFERINGS

The Trust 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 Delaware, the Board is authorized to approve rights offerings without obtaining shareholder approval.

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

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

•

the period of time the offering would remain open;

•

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

•

the title of such rights;

•

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

•

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

•

the number of rights required to purchase a single share;

•

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

•

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

•

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

- 45 -

•

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

•

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

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

TAX MATTERS

The following discussion is a brief summary of certain U.S. federal income tax considerations affecting the Trust and the purchase, ownership and disposition of the Trust’s common shares. A more detailed discussion of the tax rules applicable to the Trust 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 IRS, possibly with retroactive effect. No attempt is made to present a detailed explanation of all U.S. federal tax concerns affecting the Trust and its common shareholders.

The Trust has not sought and will not seek any ruling from the IRS regarding any matters discussed herein. No assurance can be given that the IRS 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

non-U.S.,

state or local tax.

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 Trust.

In addition, no attempt is made to address tax considerations applicable to an investor with a special tax status, such as without limitation, 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 Trust 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:

•

a citizen or individual resident of the United States (including certain former citizens and former long-term residents);

•

a corporation or other entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or any state thereof or the District of Columbia;

- 46 -

•

an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

•

a trust with respect to which a court within the United States is able to exercise primary supervision over its administration and one or more U.S. persons have the authority to control all of its substantial decisions or the trust has made a valid election in effect under applicable Treasury regulations to be treated as a U.S. person.

Taxation of the Trust

The Trust has elected to be treated as a RIC under Subchapter M of the Code. In order to qualify as a RIC, the Trust 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 Trust 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 Trust 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 Trust’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 market value of the Trust’s 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 Trust and engaged in the same, similar or related trades or businesses, or any one or more “qualified publicly traded partnerships.”

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 Trust 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 Trust 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.

one-year

period generally ending on October 31 of the calendar year (unless an election is made to use the Trust’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 the total amount of any under-distribution or over-distribution, as the case may be, from the previous year. For purposes of the excise tax, the Trust will be deemed to have distributed any income on which it paid U.S. federal income tax. While the Trust 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 Trust’s taxable income and capital gain will be distributed to entirely avoid the imposition of the excise tax. In that event, the Trust will be liable for the excise tax only on the amount by which it does not meet the foregoing distribution requirement.

- 47 -

as ordinary dividend income for U.S. federal income tax purposes to the extent of the Trust’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 Trust would be required to distribute to shareholders its earnings and profits attributable to

non-RIC

years. In addition, if the Trust 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 Trust 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 Trust 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 Trust qualifies for taxation as a RIC.

The Trust’s Investments.

Certain of the Trust’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 Trust 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 Trust 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 Trust as a RIC. Additionally, the Trust may be required to limit its activities in derivative instruments in order to enable it to maintain its RIC status.

The Trust 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 Trust. U.S. federal income tax rules are not entirely clear about issues such as when the Trust 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 Trust’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 Trust 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 Trust 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 Trust 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 Trust 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 Trust ultimately collects less on the debt instrument than its purchase price plus the market discount previously included in income, the Trust may not be able to benefit from any offsetting loss deductions.

- 48 -

The Trust 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 IRS. To the extent the tax treatment of such securities or the income from such securities differs from the tax treatment expected by the Trust, it could affect the timing or character of income recognized by the Trust, potentially requiring the Trust 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 Trust will generally be long-term capital gain or loss if the securities have been held by the Trust 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.

Because the Trust may invest in foreign securities, its income from such securities may be subject to

non-U.S.

taxes.

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 Trust will generally not be recognized by the Trust 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 Trust’s obligations with respect to the option are otherwise terminated. If the option lapses without exercise, the premiums received by the Trust from the writing of such options will generally be characterized as short-term capital gain. If the Trust enters into a closing transaction, the difference between the premiums received and the amount paid by the Trust to close out its position will generally be treated as short-term capital gain or loss. If an option written by the Trust is exercised, thereby requiring the Trust 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 Trust in the underlying security. Because the Trust 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 Trust to realize gains or losses at inopportune times.

Index options that qualify as “section 1256 contracts” will generally be treated as

“marked-to-market”

for U.S. federal income tax purposes. As a result, the Trust 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 Trust to recognize gain in advance of the receipt of cash, the Trust 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.

Taxation of Common Shareholders

Trust distributions of its

tax-exempt

interest on municipal securities, if properly reported by the Trust to its shareholders (“exempt-interest dividends”), will generally be exempt from regular federal income tax. In order for the Trust to pay exempt-interest dividends, at least 50% of the value of the Trust’s total assets must consist of

tax-exempt

obligations on a quarterly basis. If the Trust does not meet this requirement, it would not be able to pay

tax-exempt

dividends, and your distributions attributable to interest received by the Trust from any source (including distributions of

tax-exempt

interest income) would be taxable as ordinary income to the extent of the Trust’s earnings and profits.

- 49 -

The Trust will either distribute or retain for reinvestment all or part of its net capital gain. If any such gain is retained, the Trust will be subject to a corporate income tax on such retained amount. In that event, the Trust 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 Trust 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).

Distributions paid to you by the Trust from its net capital gain, if any, that the Trust 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 Trust (including dividends from net short-term capital gains) from its current or accumulated earnings and profits, other than exempt-interest dividends (“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 Trust) may qualify (i) for the dividends received deduction in the case of corporate shareholders to the extent that the Trust’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 Trust 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 Trust’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 Trust’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 Trust 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 Trust. Dividends and other distributions paid by the Trust are generally treated under the Code as received by you at the time the dividend or distribution is made. If, however, the Trust 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 Trust 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 Trust’s taxable year may be “spilled back” and treated as paid by the Trust (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.

Interest on certain “private activity bonds” is an item of tax preference subject to the alternative minimum tax on individuals. The Trust may invest a portion of its assets in municipal bonds subject to this provision so that a portion of its exempt-interest dividends is an item of tax preference to the extent such dividends represent interest received from these private activity bonds. Accordingly, investment in the Trust could cause a holder of common shares to be subject to, or result in an increased liability under, the alternative minimum tax.

- 50 -

Exempt-interest dividends are included in determining what portion, if any, of a person’s Social Security and railroad retirement benefits will be includable in gross income subject to federal income tax.

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 Trust 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 Trust.

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 Trust 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 Trust 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 Trust and capital gains from the sale or other disposition of the Trust’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 exempt-interest dividends or net capital gain (including amounts credited as an undistributed capital gain dividend) or upon the sale or other disposition of common shares of the Trust. 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 Trust’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

- 51 -

capital gain over its long-term capital loss for such taxable year). Depending on its circumstances, the Trust 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 tax even if the Trust 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 Trust’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 Trust 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 Trust are held will affect the determination of whether such withholding is required. Similarly, dividends paid in respect of common shares of the Trust 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 Trust 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 Trust 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 Trust’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 IRS.

Ordinary income dividends, capital gain dividends, and gain from the sale or other disposition of common shares of the Trust 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 Trust.

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 Trust 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 Trust 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.

TAXATION OF HOLDERS OF RIGHTS

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 beneficial interest 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.

CERTAIN PROVISIONS IN THE AGREEMENT AND DECLARATION OF TRUST AND BYLAWS

The Agreement and Declaration of Trust includes provisions that could have the effect of limiting the ability of other entities or persons to acquire control of the Trust or to change the composition of the Board. This could have the effect of depriving shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control over the Trust. Such attempts could have the effect of increasing the expenses of the Trust and disrupting the normal operation of the Trust. The Board is divided into three classes. At each annual meeting of shareholders or special meeting in lieu thereof the term of only one class of Trustees expires and only the Trustees in that one class stand for

re-election.

Trustees standing for election at an annual meeting of shareholders or special meeting in lieu thereof are elected to a three-year term. This provision could delay for up to two years the replacement of a majority of the Board. A Trustee may be removed from office for cause only, and only by the action of a majority of the remaining Trustees followed by a vote of the holders of at least 75% of the shares then entitled to vote for the election of the respective Trustee.

In addition, the Trust’s Agreement and Declaration of Trust requires the favorable vote of a majority of the Board followed by the favorable vote of the holders of at least 75% of the outstanding shares of each affected class or series of the Trust, voting separately as a class or series, to approve, adopt or authorize certain transactions with 5% or greater holders of a class or series of shares and their associates, unless the transaction has been approved by at least 80% of the Trustees, in which case “a majority of the outstanding voting securities” (as defined in the Investment Company Act) of the Trust shall be required. These voting requirements are in addition to any regulatory relief required from the SEC with respect to such transaction. For purposes of these provisions, a 5% or greater holder of a class or series of shares (a “Principal Shareholder”) refers to any person who, whether directly or indirectly and whether alone or together with its affiliates and associates, beneficially owns 5% or more of the outstanding shares of all outstanding classes or series of shares of beneficial interest of the Trust.

- 53 -

The 5% holder transactions subject to these special approval requirements are:

•

the merger or consolidation of the Trust or any subsidiary of the Trust with or into any Principal Shareholder;

•

the issuance of any securities of the Trust to any Principal Shareholder for cash (other than pursuant to any automatic dividend reinvestment plan);

•

the sale, lease or exchange of all or any substantial part of the assets of the Trust to any Principal Shareholder, except assets having an aggregate fair market value of less than 2% of the total assets of the Trust, aggregating for the purpose of such computation all assets sold, leased or exchanged in any series of similar transactions within a twelve-month period; or

•

the sale, lease or exchange to the Trust or any subsidiary of the Trust, in exchange for securities of the Trust, of any assets of any Principal Shareholder, except assets having an aggregate fair market value of less than 2% of the total assets of the Trust, aggregating for purposes of such computation all assets sold, leased or exchanged in any series of similar transactions within a twelve-month period.

To convert the Trust to an

open-end

investment company, the Trust’s Agreement and Declaration of Trust requires the favorable vote of a majority of the Board followed by the favorable vote of the holders of at least 75% of the outstanding shares of each affected class or series of shares of the Trust, voting separately as a class or series, unless such conversion has been approved by at least 80% of the Trustees, in which case “a majority of the outstanding voting securities” (as defined in the Investment Company Act) of the Trust shall be required. The foregoing vote would satisfy a separate requirement in the Investment Company Act that any conversion of the Trust to an

open-end

investment company be approved by the shareholders. If approved in the foregoing manner, we anticipate conversion of the Trust to an

open-end

investment company might not occur until 90 days after the shareholders’ meeting at which such conversion was approved and would also require at least 10 days’ prior notice to all shareholders. Conversion of the Trust to an

open-end

investment company would require the redemption of any outstanding preferred shares, which could eliminate or alter the leveraged capital structure of the Trust with respect to the common shares. Following any such conversion, it is also possible that certain of the Trust’s investment policies and strategies would have to be modified to assure sufficient portfolio liquidity, including in order to comply with Rule

22e-4

under the Investment Company Act. In the event of conversion, the common shares would cease to be listed on the NYSE or other national securities exchanges or market systems. Shareholders of an

open-end

investment company may require the company to redeem their shares at any time, except in certain circumstances as authorized by or under the Investment Company Act, at their NAV, less such redemption charge, if any, as might be in effect at the time of a redemption. The Trust expects to pay all such redemption requests in cash, but reserves the right to pay redemption requests in a combination of cash or securities. If such partial payment in securities were made, investors may incur brokerage costs in converting such securities to cash. If the Trust were converted to an

open-end

fund, it is likely that new shares would be sold at NAV plus a sales load. The Board believes, however, that the

closed-end

structure is desirable in light of the Trust’s investment objectives and policies. Therefore, you should assume that it is not likely that the Board would vote to convert the Trust to an

open-end

fund.

For the purposes of calculating “a majority of the outstanding voting securities” under the Trust’s Agreement and Declaration of Trust, each class and series of the Trust shall vote together as a single class, except to the extent required by the Investment Company Act or the Trust’s Agreement and Declaration of Trust with respect to any class or series of shares. If a separate vote is required, the applicable proportion of shares of the class or series, voting as a separate class or series, also will be required.

The Board has determined that provisions with respect to the Board and the shareholder voting requirements described above, which voting requirements are greater than the minimum requirements under Delaware law or the Investment Company Act, are in the best interests of shareholders generally. Reference should be made to the Agreement and Declaration of Trust on file with the SEC for the full text of these provisions.

- 54 -

The Trust’s Bylaws generally require that advance notice be given to the Trust in the event a shareholder desires to nominate a person for election to the Board or to transact any other business at an annual meeting of shareholders. Notice of any such nomination or business must be delivered to or received at the principal executive offices of the Trust 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 shareholder must be accompanied by certain information as provided in the Bylaws. Reference should be made to the Bylaws on file with the SEC for the full text of these provisions.

CLOSED-END

FUND STRUCTURE

The Trust 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 Trust to an

open-end

mutual fund, which would also require a vote of the shareholders of the Trust.

REPURCHASE OF COMMON SHARES

Shares of

closed-end

investment companies often trade at a discount to their NAVs and the Trust’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 Trust’s common shares will be determined by such factors as relative demand for and supply of such common shares in the market, the Trust’s NAV, general market and economic conditions, market sentiment and other factors beyond the control of the Trust. See “Net Asset Value” and “Description of Shares—Common Shares.” Although the Trust’s common shareholders will not have the right to redeem their common shares, the Trust 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 Trust’s common shares, you should be aware that the acquisition of common shares by the Trust will decrease the capital of the Trust and, therefore, may have the effect of increasing the Trust’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 Securities Exchange Act of 1934, 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.

- 55 -

PLAN OF DISTRIBUTION

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.

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

- 56 -

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.

CAUTIONARY NOTICE REGARDING FORWARD-LOOKING STATEMENTS

This Prospectus Supplement, the accompanying Prospectus and the SAI contain “forward-looking statements.” Forward-looking statements can be identified by the words “may,” “will,” “intend,” “expect,” “estimate,” “continue,” “plan,” “anticipate,” and similar terms and the negative of such terms. Such forward-looking statements may be contained in this Prospectus Supplement as well as in the accompanying Prospectus. By their nature, all forward-looking statements involve risks and uncertainties, and actual results could differ materially from those contemplated by the forward-looking statements. Several factors that could materially affect our actual results are the performance of the portfolio of securities we hold, the price at which our shares will trade in the public markets and other factors discussed in our periodic filings with the SEC.

Although we believe that the expectations expressed in our forward-looking statements are reasonable, actual results could differ materially from those projected or assumed in our forward-looking statements. Our future financial condition and results of operations, as well as any forward-looking statements, are subject to change and are subject to inherent risks and uncertainties, such as those disclosed in the “Risks” section of the accompanying Prospectus. All forward-looking statements contained or incorporated by reference in this Prospectus Supplement or the accompanying Prospectus are made as of the date of this Prospectus Supplement or the accompanying Prospectus, as the case may be. Except for our ongoing obligations under the federal securities laws, we do not intend, and we undertake no obligation, to update any forward-looking statement. The forward-looking statements contained in this Prospectus Supplement, the accompanying Prospectus and the SAI are excluded from the safe harbor protection provided by Section 27A of the Securities Act.

Currently known risk factors that could cause actual results to differ materially from our expectations include, but are not limited to, the factors described in the “Risks” section of the accompanying Prospectus. We urge you to review that section carefully for a more detailed discussion of the risks of an investment in our common shares.

PROSPECTUS SUPPLEMENT SUMMARY

The following summary is qualified in its entirety by reference to the more detailed information included elsewhere in this Prospectus Supplement and in the accompanying Prospectus and in the SAI.


The Trust		BlackRock Taxable Municipal Bond Trust is a diversified, closed-end management investment company. The Trust’s primary investment objective is to seek high current income, with a secondary objective of capital appreciation. There can be no assurance that the Trust’s investment objectives will be achieved or that the Trust’s investment program will be successful. The Trust’s common shares are listed for trading on the NYSE under the symbol “BBN.”

Investment Advisor		BlackRock Advisors, LLC is the Trust’s investment adviser. The Advisor receives a monthly fee in arrears at an annual rate equal to 0.55% of the average daily value of the Trust’s Managed Assets. “Managed Assets” means the total assets of the Trust (including any assets attributable to money borrowed for investment purposes) minus the sum of the Trust’s accrued liabilities (other than money borrowed for investment purposes).

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 objectives and policies as described in the accompanying Prospectus under “The Trust’s Investments” within approximately three months of the receipt of such proceeds; however, the identification of appropriate investment opportunities pursuant to the Trust’s investment style or changes in market conditions could result in the Trust’s anticipated investment period extending to as long as six months. Such investments may be delayed if suitable investments are unavailable at the time or for other reasons, such as market volatility and lack of liquidity in the markets of suitable investments. Pending such investment, it is anticipated that the proceeds will be primarily 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 Trust, including any proceeds raised from the offering, may be used to pay distributions in accordance with the Trust’s distribution policy and may be a return of capital.

Computershare Trust Company, N.A.’s (the “Reinvestment Plan Agent”) fees for the handling of the reinvestment of dividends will be paid by the Trust. However, you will pay a $0.02 per share fee incurred in connection with open-market purchases, which will be deducted from the value of the dividend. You will also be charged a $2.50 sales fee and pay a $0.15 per share fee if you direct the Reinvestment Plan Agent to sell your common shares held in a dividend reinvestment account. Per share fees include any applicable brokerage commissions the Reinvestment Plan Agent is required to pay.

(5)

Assumes the use of leverage in the form of reverse repurchase agreements representing [●]% of Managed Assets (as defined above) at an annual interest expense to the Trust of [●]%, which is based on current market conditions. The actual amount of interest expense borne by the Trust will vary over time in accordance with the level of the Trust’s use of reverse repurchase agreements and variations in market interest rates. Interest expense is required to be treated as an expense of the Trust for accounting purposes.

Example

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) the Fee Waiver Agreement described above is only in effect for the first year, since it expires on June 30, 2028, and (ii) a 5% annual return:

1 Year

3 Years

5 Years

10 Years

Total expenses incurred

[●]

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, that the rate listed under Total Annual Expenses remains the same each year and that all dividends and distributions are reinvested at net asset value. Actual expenses may be greater or less than those assumed. Moreover, the Trust’s actual rate of return may be greater or less than the hypothetical 5% return shown in the example.

USE OF PROCEEDS

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 Trust’s investment objectives 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 objectives and policies within approximately three months of the receipt of such proceeds; however, the identification of appropriate investment opportunities pursuant to the Trust’s investment style or changes in market conditions could result in the Trust’s anticipated investment period extending to as long as six months. Such investments may be delayed if suitable investments are unavailable at the time or for other reasons, such as market volatility and lack of liquidity in the markets of suitable investments. Pending such investment, it is anticipated that the proceeds will be primarily 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 Trust, including any proceeds raised from the offering, may be used to pay distributions in accordance with the Trust’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 Trust. In general terms, a return of capital would involve a situation in which a Trust distribution (or a portion thereof) represents a return of a portion of a shareholder’s investment in the Trust, rather than making a distribution that is funded from the Trust’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.

BLACKROCK TAXABLE MUNICIPAL BOND TRUST

[

] Rights for [

] Common Shares of Beneficial Interest

Issuable Upon the Exercise of

Transferable Rights to Acquire Common Shares of Beneficial Interest

BlackRock Taxable Municipal Bond Trust (the “Trust,” “we,” “us” or “our”) is issuing subscription rights (the “Rights”) to our common shareholders (the “Common Shareholders”) to subscribe for an aggregate of [●] common shares of beneficial interest (each, a “Common Share” and collectively, the “Common Shares”).

The Trust is a diversified,

closed-end

The Common Shares are listed on the New York Stock Exchange (“NYSE”) under the symbol “BBN.” Common Shareholders of record on [●], 2026 (the “Record Date”) will receive [●] Right for each Common Share held. These Rights are transferable and will allow the holders thereof to purchase additional Common Shares. The Rights will be listed for trading on the [●] under the symbol “[●]” during the course of the Rights offering.

The Rights entitle their holders to purchase [●] new Common Share for every [●] Rights held. Any Common Shareholder who owns fewer than [●] Common Shares as of the close of business on the Record Date may subscribe for [●] full Common Share. Common Shareholders as of the close of business on the Record Date who fully exercise all Rights initially issued to them (other than those Rights that cannot be exercised because they represent the right to acquire less than one Common Share) will be entitled to subscribe for additional Common Shares that remain unsubscribed as a result of any unexercised Rights. This over-subscription privilege is subject to a number of limitations and subject to allotment.

The 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 a Common Share on the NYSE on the date on which the Rights offering expires, as such date may be extended from time to time, and each of the [● (●)] preceding trading days (the “Formula Price”). If, however, the Formula Price is less than [●]% of the net asset value (“NAV”) per Common Share at the close of trading on the NYSE on the Expiration Date (as defined below), then the Subscription Price will be [●]% of the Trust’s NAV per Common Share at the close of trading on the NYSE on the Expiration Date. All offering expenses, including sales commissions, will be borne by the Advisor, and not the Trust or any Common Shareholders. The Rights offering will expire at 5:00 p.m., Eastern time, on [●], 2026, unless extended as described in this Prospectus Supplement (the “Expiration Date”).

R-1

On [●], 2026 (the last trading date prior to the Common Shares trading

ex-Rights),

the last reported net asset value per share of the Common Shares was $[●] and the last reported sales price per share of Common Shares on the NYSE was $[●], representing a [premium] to net asset value of [●]%.

CAUTIONARY NOTICE REGARDING FORWARD-LOOKING STATEMENTS

This Prospectus Supplement, the accompanying Prospectus and the SAI contain “forward-looking statements.” Forward-looking statements can be identified by the words “may,” “will,” “intend,” “expect,” “estimate,” “continue,” “plan,” “anticipate,” and similar terms and the negative of such terms. Such forward-looking statements may be contained in this Prospectus Supplement as well as in the accompanying Prospectus and in the SAI. By their nature, all forward-looking statements involve risks and uncertainties, and actual results could differ materially from those contemplated by the forward-looking statements. Several factors that could materially affect our actual results are the performance of the portfolio of securities we hold, the price at which our shares will trade in the public markets and other factors discussed in our periodic filings with the SEC.

Although we believe that the expectations expressed in our forward-looking statements are reasonable, actual results could differ materially from those projected or assumed in our forward-looking statements. Our future financial condition and results of operations, as well as any forward-looking statements, are subject to change and are subject to inherent risks and uncertainties, such as those disclosed in the “Risks” section of the accompanying Prospectus and “Special Characteristics and Risks of the Rights Offering” in this Prospectus Supplement. All forward-looking statements contained or incorporated by reference in this Prospectus Supplement or the accompanying Prospectus, or in the SAI, are made as of the date of this Prospectus Supplement or the accompanying Prospectus or SAI, as the case may be. Except for our ongoing obligations under the federal securities laws, we do not intend, and we undertake no obligation, to update any forward-looking statement. The forward-looking statements contained in this Prospectus Supplement, the accompanying Prospectus and the SAI are excluded from the safe harbor protection provided by Section 27A of the Securities Act of 1933, as amended (the “Securities Act”).

Currently known risk factors that could cause actual results to differ materially from our expectations include, but are not limited to, the factors described in the “Risks” section of the accompanying Prospectus as well as in the “Special Characteristics and Risks of the Rights Offering” section of this Prospectus Supplement. We urge you to carefully review those sections for a more detailed discussion of the risks of an investment in the Common Shares.

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 beneficial interest of BlackRock Taxable Municipal Bond Trust (the “Trust,” “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 Trust. [●] Common Shares of the Trust are outstanding as of [●], 2026. [●] Rights will be required to purchase one Common Share. Shares of the Trust, as a closed-end fund, can trade at a discount to net asset value (“NAV”). Upon exercise of the Rights offering, Trust 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 Trustees of the Trust (the “Board”) to eliminate the over-subscription privilege.]] [●] Common Shares of the Trust will be issued if all Rights are exercised. See “Terms of the Rights Offering.” The Trust has declared monthly distributions payable on [●], 2026 with a record date of [●], 2026. Any Common Shares issued as a result of the Rights offering will not be record date shares for the Trust’s monthly distribution to be paid on [●], 2026 and will not be entitled to receive such distribution. The exercise of Rights by a Rights holder is irrevocable.

R-5


Title		Subscription Rights to Acquire Common Shares of Beneficial Interest.

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 Trust’s Common Shares on the New York Stock Exchange (“NYSE”) on the Expiration Date (as defined below) and each of the [●] preceding trading days (the “Formula Price”). If, however, the Formula Price is less than [●]% of the NAV per Common Share of the Trust’s Common Shares at the close of trading on the NYSE on the Expiration Date, then the Subscription Price will be [●]% of the Trust’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 Trust’s Common Shares as of the close of business on [●], 2026 (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 Trust 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 Trust 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 (other than those Rights that cannot be exercised because they represent the right to acquire less than one Common Share) generally are entitled, subject to the limitations described herein, 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 Trust. Common Shares acquired pursuant to the primary over-subscription privilege are subject to allotment. Holders of Rights acquired in the secondary market may not participate in the primary over-subscription privilege.

		[In addition, the Trust, 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 Trust 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

R-6


		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 Trust. 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 Trust 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,” “Sale of Rights” 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 [●], 2026 (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 Trust at any time for any reason before the Expiration Date. If the Trust terminates the Rights offering, the Trust will issue a press release announcing such termination and will direct the Subscription Agent (defined below) to return, without interest, all subscription proceeds received to such shareholders who had elected to purchase Common Shares.

Distribution Arrangements		[●]

Offering Expenses		The expenses of the Rights offering are expected to be approximately $[●] and will be borne by holders of the Trust’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 Subscription Agent (defined below) for sale. Any Rights submitted to the Subscription Agent for sale

R-7


		must be received by the Subscription Agent prior to [5:00 PM, Eastern Time], on or before [●], 2026, [●] 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 Subscription Agent receives Rights for sale in a timely manner, the Subscription Agent will use its best efforts to sell the Rights on the [●]. The Subscription 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 Subscription 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 Subscription 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 Trust nor the Subscription 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 Subscription 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.”

R-8


Use of Proceeds		The Trust 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 Trust’s Common Shares on the NYSE on [●], 2026) 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 Trust’s investment objectives 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 Trust’s investment style or changes in market conditions may cause the investment period to extend as long as six months. Such investments may be delayed if suitable investments are unavailable at the time or for other reasons, such as market volatility and lack of liquidity in the markets of suitable investments. Pending such investment, the proceeds will be held 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 Trust, including any proceeds raised from the offering, may be used to pay distributions in accordance with the Trust’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 Trust. In general terms, a return of capital would involve a situation in which a Trust distribution (or a portion thereof) represents a return of a portion of a shareholder’s investment in the Trust, rather than making a distribution that is funded from the Trust’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.”

DESCRIPTION OF THE RIGHTS OFFERING

Terms of the Rights Offering

The Trust is issuing to Record Date Shareholders Rights to subscribe for Common Shares of the Trust. 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 Trust’s Common Shares on the NYSE on the Expiration Date (as defined below) and each of the [●] 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 Trust’s Common Shares at the close of trading on

R-9

the NYSE on the Expiration Date, then the Subscription Price will be [●]% of the Trust’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 Trust’s Common Shares on the NYSE on [●], 2026. 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 Trust 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 Trust on or before the close of business on [●], 2026 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 [●], 2026, and ends at [5:00 PM, Eastern Time] on [●], 2026 (the “Expiration Date”), unless otherwise extended. Shares of the Trust, as a

closed-end

fund, can trade at a discount to NAV. Upon exercise of the Rights offering, Trust shares may 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. The Trust has declared monthly distributions payable on [

●

], 2026 with a record date of [

●

],2026.

Any Common Shares issued as a result of the Rights offering will not be Record Date shares for the Trust’s monthly distribution to be paid on

[

●

]

, 2026 and will not be entitled to receive such distribution.

The Trust 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 “Subscription 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 Subscription Agent. Although no assurance can be

R-10

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 Trust at any time for any reason before the Expiration Date. If the Trust terminates the Rights offering, the Trust will issue a press release announcing such termination and will direct the Subscription Agent to return, without interest, all subscription proceeds received to such shareholders who had elected to purchase Common Shares.

Nominees who hold the Trust’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 Subscription 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 Trust’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.”]

Conditions of the Rights Offering

The Rights offering is being made in accordance with the Investment Company Act of 1940, 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.

[Over-Subscription Privilege

Rights holders [who are Record Date Shareholders and who fully exercise all Rights initially issued to them (other than those Rights that cannot be exercised because they represent the right to acquire less than one Common Share)] 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. 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 Trust 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.

[Record Date Shareholders who fully exercise all Rights initially issued to them (other than those Rights that cannot be exercised because they represent the right to acquire less than one Common Share)] 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 Trust.

Common Shares acquired pursuant to the over-subscription privilege are subject to allotment.

[In addition, the Trust, 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 Trust 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 Trust.

Holders of

Rights acquired in the secondary market may not participate in the over-subscription privilege

In the event that the Subscription Price is lower than the Trust’s NAV per share, any secondary over-subscription shares issued by the Trust will not result in the ratio of the Rights offering exceeding one new share for each three Rights.]

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.

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 Trust. 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.

The formula to be used in allocating the Excess Shares is as follows:


Shareholder’s Record Date Position	X	Excess Shares Remaining
Total Record Date Position of All Over-Subscribers

Banks, broker-dealers, trustees and other nominee holders of Rights will be required to certify to the Subscription 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

R-12

beneficial owner’s subscription was exercised in full. [Nominees should also notify holders purchasing Rights in the secondary market that such Rights may not participate in the over-subscription privilege.]

The Trust 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.]

[Dealer Manager

[●] (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.]

Sale of Rights

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 through their broker or other financial intermediary. Holders of Rights attempting to sell any unexercised Rights in the open market through their broker or financial advisor may be charged a commission or incur other transaction expenses and should consider the commissions and fees charged prior to selling their Rights on the open market.

[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.

Holders of Rights who are unable or do not wish to exercise any or all of their Rights may contact the Subscription Agent to facilitate the sale of any unexercised Rights. The Subscription Agent will contact the Dealer Manager or other brokers in order to assist Rights holders whose Rights are not currently held at a broker-dealer or other applicable financial intermediary to facilitate the sale of the Rights. Shareholders of record whose addresses are outside the United States, or who have an APO or FPO address, are encouraged to contact the Subscription Agent to facilitate the sale of their Rights if they are otherwise unable or unwilling to exercise the Rights. The selling Rights holder will pay all applicable brokerage commissions incurred. There can be no assurance that the Subscription Agent will be able to facilitate the sale of any of Rights and neither the Trust nor the Subscription Agent has guaranteed any minimum sales price for the Rights.

R-13

Method of Transferring Rights

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 Subscription 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 Subscription 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 Trust nor the Subscription 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 Subscription Agent (which will be paid by the Trust 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 Trust or the Subscription Agent.

The Trust 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”).

Subscription Agent

The Subscription Agent is [●]. The Subscription Agent will receive from the Trust 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 Trust will indirectly pay such amount.

Information Agent

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

Method of Exercise of Rights

Rights may be exercised by completing and signing the Subscription Certificate and delivering the completed and signed Subscription Certificate to the Subscription 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 Subscription 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 Subscription Agent at the following address:

R-14

If By Mail:

BlackRock Taxable Municipal Bond Trust

[●]

If By Overnight Courier:

BlackRock Taxable Municipal Bond Trust

[●]

Payment for Shares

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

(1)

A holder of Rights can send the Subscription Certificate, together with payment in the form of a check (which must include the name of the shareholder on the check) for the Common Shares subscribed for in the Rights offering and, if eligible, for any additional Common Shares subscribed for pursuant to the over-subscription privilege, to the Subscription Agent based on the Subscription Price. To be accepted, the payment, together with the executed Subscription Certificate, must be received by the Subscription Agent at one of the addresses noted above prior to [5:00 PM, Eastern Time] on the Expiration Date. The Subscription Agent will deposit all share purchase checks received by it prior to the final due date into a segregated account pending proration and distribution of Common Shares. The Subscription Agent will not accept cash as a means of payment for Common Shares.

(2)

Alternatively, a subscription will be accepted by the Subscription Agent if, prior to [5:00 PM, Eastern Time] on the Expiration Date, the Subscription Agent has received a written notice of guaranteed delivery by mail or email from a bank, trust company, or a NYSE member, guaranteeing delivery of a properly completed and executed Subscription Certificate. In order for the notice of guarantee to be valid, full payment for the Common Shares at the Subscription Price must be received with the notice. The Subscription Agent will not honor a notice of guaranteed delivery unless a properly completed and executed Subscription Certificate is received by the Subscription Agent by the close of business on the [second] Business Day after the Expiration Date. The notice of guaranteed delivery must be emailed to the Subscription Agent at [●] or delivered to the Subscription Agent at one of the addresses noted above.

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 TAXABLE MUNICIPAL BOND TRUST 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 subscription makes payment of an insufficient amount, the Trust reserves the right to take any or all of the following actions: (i) reallocate such subscribed and

unpaid-for

Common Shares to Record Date Shareholders exercising the over-subscription privilege who did not receive the full over-subscription requested; (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

R-15

Rights or any over-subscription privilege; and (iii) 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 (in other words, retain such payments) and to enforce the exercising Rights holder’s relevant payment obligation.

Any payment required from a holder of Rights must be received by the Subscription 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 Subscription 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 Subscription Agent on or prior to the Expiration Date. Any excess payment to be refunded by the Trust 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 Subscription Agent, will be mailed by the Subscription 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 Subscription 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 Subscription Agent shall be held by the Subscription Agent as agent for the Trust and deposited in one or more bank accounts. Such funds may be invested by the Subscription Agent in: bank accounts, short-term certificates of deposit, bank repurchase agreements, and disbursement accounts with commercial banks meeting certain standards. The Subscription 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 Subscription 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 Trust 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 TRUST.

THE METHOD OF DELIVERY OF SUBSCRIPTION CERTIFICATES AND PAYMENT OF THE SUBSCRIPTION PRICE TO THE SUBSCRIPTION 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 SUBSCRIPTION 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.

R-16

All questions concerning the timeliness, validity, form and eligibility of any exercise of Rights will be determined by the Trust, whose determinations will be final and binding. The Trust 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 Trust determines in its sole discretion. Neither the Trust nor the Subscription 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.

Foreign Restrictions

Offering documents, including Subscription Certificates, will not be mailed to Record Date Shareholders whose addresses are outside the United States (for these purposes, the United States includes the District of Columbia and the territories and possessions of the United States) or who have an APO or FPO address (the “Foreign Shareholders”) if such mailing cannot be made into

the non-U.S. jurisdiction

without additional registration and incurring other expense that the Board has determined is not in the best interest of the Trust and its shareholders. In such cases, unless determined to be not in the best interest of the Trust and its shareholders in accordance with the previous sentence, the Subscription Agent will send a letter via regular mail to Foreign Shareholders who own Common Shares directly (“Direct Foreign Shareholders”), as opposed to in “street name” with a broker or other financial intermediary, to notify them of the Rights offering. Direct Foreign Shareholders who wish to exercise their Rights should contact the Information Agent, as described above under “Information Agent,” to facilitate the exercise of such Rights and for instructions or any other special requirements that may apply in order for such Direct Foreign Shareholder to exercise its Rights. Direct Foreign Shareholders who wish to sell their Rights should contact the Subscription Agent and follow the procedures described above under “Sale of Rights.” Direct Foreign Shareholders are encouraged to contact the Trust or the Subscription Agent as far in advance of the Expiration Date as possible to ensure adequate time for their Rights to be exercised or sold. Foreign Shareholders who own Common Shares in “street name” through a broker or other financial intermediary should contact such broker or other financial intermediary with respect to any exercise or sale of Rights.

Employee Benefit Plan and IRA Considerations

[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. Such requirements may include prudence and diversification requirements and require that investments be made in accordance with the

R-17

documents governing the fiduciary. The exercise of Rights by a 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 utilizing a prohibited transaction exemption change.

Due to the complexity of these rules and the penalties for noncompliance, fiduciaries of Benefit Plans 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 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, that the rate listed under Total Annual Expenses remains the same each year and that all dividends and distributions are reinvested at net asset value. Actual expenses may be greater or less than those assumed. Moreover, the Trust’s actual rate of return may be greater or less than the hypothetical 5% return shown in the example.

USE OF PROCEEDS

The Trust 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 Trust’s Common Shares on the NYSE on [●], 2026), 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 Trust’s investment objectives 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 objectives and policies within approximately three months of the receipt of such proceeds; however, the identification of appropriate investment opportunities pursuant to the Trust’s investment style or changes in market conditions could result in the Trust’s anticipated investment period extending to as long as six months. Such investments may be delayed if suitable investments are unavailable at the time or for other reasons, such as market volatility and lack of liquidity in the markets of suitable investments. Such investments may be delayed if suitable investments are unavailable at the time or for other reasons, such as market volatility and lack of liquidity in the markets of suitable investments. 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 Trust, including any proceeds raised from the offering, may be used to pay distributions in accordance with the Trust’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 Trust. In general terms, a return of capital would involve a situation in which a Trust distribution (or a portion thereof) represents a return of a portion of a shareholder’s investment in the Trust, rather than making a distribution that is funded from the Trust’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.

CAPITALIZATION

The following table sets forth the unaudited capitalization of the Trust as of [●], 2026 and its adjusted capitalization assuming the Common Shares available in the Rights offering discussed in this Prospectus Supplement had been issued.

SPECIAL CHARACTERISTICS AND RISKS OF THE RIGHTS OFFERING

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 Trust 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 Trust 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). As a result, existing Common Shareholders may experience immediate dilution even if they fully exercise their Rights. Such dilution, if any, 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 Trust will pay expenses associated with the Rights offering, estimated at approximately $[●]. In addition, the Trust 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 Trust, 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 Trust’s Common Shareholders. See “Table of Fees and Expenses” in this Prospectus Supplement and “Summary of Trust Expenses” in the accompanying Prospectus for more information.

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 Trust’s NAV per Common Share on the Expiration Date, because:

•

the offered Common Shares are being sold at less than their current NAV;

•

you will indirectly bear the expenses of the Rights offering; and

•

the number of Common Shares outstanding after the Rights offering will have increased proportionately more than the increase in the amount of the Trust’s net assets.

On the other hand, if the Subscription Price is above the Trust’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:

•

the offered Common Shares are being sold at more than their current NAV after deducting the expenses of the Rights offering; and

•

the number of Common Shares outstanding after the Rights offering will have increased proportionately less than the increase in the amount of the Trust’s net assets.

[Furthermore, if you do not participate in the secondary over-subscription, if it is available, your percentage ownership will also be diluted.] The Trust 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

R-21

Rights will be exercised or what the Subscription Price per Common Share will be. 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 the estimated Subscription Price of $[●]:


[Scenario 1: (assumes NAV per share is above Subscription Price)(1)

NAV(2)			[●]
Subscription Price(3)			[●]
Reduction in NAV ($)(4)			[●]
Reduction in NAV (%)			[●]]


[Scenario 2: (assumes NAV per share is below Subscription Price)(1)

NAV(2)			[●]
Subscription Price(3)			[●]
Increase in NAV ($)(4)			[●]
Increase in NAV (%)			[●]]

(1)	Both examples assume the full primary subscription [and secondary over-subscription privilege] are exercised. Actual amounts may vary due to rounding.

(2)	For illustrative purposes only; reflects the Trust’s NAV per Common Share as of [●], 2026. It is not known at this time what the NAV per Common Share will be on the Expiration Date.

(3)	For illustrative purposes only; reflects an estimated Subscription Price of $[●] based upon [●]% of the last reported sales price of the Trust’s Common Shares on the NYSE on [●], 2026. It is not known at this time what the Subscription Price will be on the Expiration Date.

(4)	Assumes $[●] in estimated offering expenses.

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 Trust. The Trust cannot give assurance, however, that a market for the Rights will develop or that the Rights will have any marketable value.

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

Risks of Investing in Rights.

Shares of

closed-end

funds such as the Trust frequently trade at a discount to NAV. The Subscription Price may be greater than the market price of a Common Share on the Expiration Date. If that is the case, 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 Trust’s amount of leverage outstanding will decrease. The leverage of the Trust as of [●], 2026 was approximately [●]% of the Trust’s Managed Assets. After the completion of the Rights offering, the amount of leverage outstanding is expected to decrease to approximately [●]% of the Trust’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 Trust’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 Trust’s Common Shares may decrease more quickly than would otherwise be the case, and distributions on the Common Shares could be

R-22

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.

The Trust’s leveraging strategy may not be successful.

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 Trust achieves any benefits.

TAXATION

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 Trust.

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

•

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 Common Share with respect to which the Right was issued (the “Old Common Share”) will not change, unless either the fair market value of the Right on the date of distribution is at least 15% of the fair market value of the Old Common Share, or such Common Shareholder affirmatively elects (in the manner set out in Treasury Regulations under the Code) to allocate to the Right a portion of the basis of the Old Common Share. If the basis of a Right or Old Common Share changes, such Common Shareholder must allocate basis between the Old Common Share and the Right in proportion to their fair market values on the date of distribution.

•

The basis of a Right purchased will generally be its purchase price.

•

A Common Shareholder’s holding period in a Right issued includes the holding period of the Old Common Share.

•

A Common Shareholder will not recognize a loss if a Right distributed to such Common Shareholder expires unexercised because the basis of the Old Common Share may be allocated to a Right only if the Right is sold or 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 a Right issued to Record Date Shareholders will depend on whether the Old Common Share 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.

R-23

•

No gain or loss will be recognized by a Common Shareholder upon the exercise of a Right, and the basis of any Common Share acquired upon exercise (the “New Common Share”) will equal the sum of the basis, if any, of the Right and the Subscription Price for the New Common Share. The holding period for the New Common Share will begin on the date when the Right is exercised (or, in the case of a Right purchased in the market, potentially the day after the date of exercise).

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 Trust 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 Trust. These provisions are subject to change by legislative or administrative action, and any such change may be retroactive.

PLAN OF DISTRIBUTION

[Distribution Arrangements

[●] 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 Trust 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 Trust 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 Trust 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 Subscription Agent for sale by Record Date Shareholders 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

R-24

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 Trust and the dealer manager fee with respect to such proceeds will be paid by the Trust 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 Trust. 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 [●]% of the aggregate price of the Common Shares sold by the respective Selling Group Member. Neither the Trust 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.”

R-25

In the ordinary course of their businesses, the Dealer Manager and/or its affiliates may engage in investment banking or financial transactions with the Trust, 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 Trust or its affiliates.

The principal business address of the Dealer Manager is [●].

Compensation to Dealer Manager

Pursuant to the Dealer Manager Agreement, the Trust 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 Trust, 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 Trust or the Advisor to the Dealer Manager in connection with the Rights offering.

LEGAL MATTERS

Willkie Farr & Gallagher LLP, New York, New York, serves as counsel to the Trust. Certain legal matters in connection with the common shares will be passed upon for the Trust by Morris, Nichols, Arsht & Tunnell LLP. [Certain legal matters will be passed upon by [●] as special counsel to the Dealer Manager in connection with the Rights offering.]

FINANCIAL STATEMENTS

The audited annual financial statements of the Trust for the fiscal year ended December 31, 202[●] [and the unaudited financial statements for the six months ended June 30, 202[●]] are incorporated by reference into this Prospectus Supplement, the accompanying Prospectus and the SAI.

THE TRUST

The Trust is a diversified, closed-end management investment company registered under the Investment Company Act. The Trust was formed as a Delaware statutory trust on June 7, 2010 pursuant to an initial Agreement and Declaration of Trust of the Trust and the Certificate of Trust filed with the Secretary of State of the State of Delaware and is governed by pursuant to the Trust’s Agreement and Declaration of Trust which is governed by the laws of the State of Delaware. The Trust’s investment adviser is BlackRock Advisors, LLC (the “Advisor”).

The common shares of the Trust are listed on the New York Stock Exchange (“NYSE”) under the symbol “BBN.” As of May 4, 2026, the Trust has 61,792,514 common shares outstanding.

INVESTMENT OBJECTIVE AND POLICIES

Investment Restrictions

The Trust has adopted restrictions and policies relating to the investment of the Trust’s assets and its activities. Certain of the restrictions are fundamental policies of the Trust and may not be changed without the approval of the holders of a majority of the Trust’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 Trust’s outstanding shares of preferred shares (“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 Trust’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 Trust may not:

Invest 25% or more of the value of its Managed Assets in any one industry, provided that this limitation does not apply to securities of the U.S. Government, any state government or their respective agencies, or instrumentalities and securities backed by the credit of any federal or state governmental entity.

Issue senior securities or borrow money other than as permitted by the Investment Company Act or pledge its assets other than to secure such issuances or in connection with hedging transactions, short sales, when-issued and forward commitment transactions and similar investment strategies.

Make loans of money or property to any person, except through loans of portfolio securities, the purchase of fixed income securities consistent with the Trust’s investment objectives and policies or the entry into repurchase agreements.

Underwrite the securities of other issuers, except to the extent that in connection with the disposition of portfolio securities or the sale of its own securities the Trust may be deemed to be an underwriter.

Purchase or sell real estate or interests therein other than municipal securities secured by real estate or interests therein, provided that the Trust may hold and sell any real estate acquired in connection with its investment in portfolio securities.

Purchase or sell commodities or commodity contracts for any purposes except as, and to the extent, permitted by applicable law without the Trust becoming subject to registration with the Commodity Futures Trading Commission (the “CFTC”) as a commodity pool.

For purposes of applying the limitation set forth in subparagraph (1) above, securities of the U.S. Government, any state government or their respective agencies, or instrumentalities and securities backed by the credit of any

S-3

federal or state governmental entity are not considered to represent industries. However, obligations backed only by the assets and revenues of non-governmental issuers may for this purpose be deemed to be issued by such non-governmental issuers. Thus, the 25% limitation would apply to such obligations. It is nonetheless possible that the Trust may invest more than 25% of its total assets in a broader economic sector of the market for municipal obligations, such as revenue obligations of hospitals and other health care facilities or electrical utility revenue obligations.

For the purpose of applying the limitation set forth in subparagraph (1) above, a governmental issuer shall be deemed the sole issuer of a security when its assets and revenues are separate from other governmental entities and its securities are backed only by its assets and revenues. Similarly, in the case of a non-governmental issuer, such as an industrial corporation or a privately owned or operated hospital, if the security is backed only by the assets and revenues of the non-governmental issuer, then such non-governmental issuer would be deemed to be the sole issuer. Where a security is backed by the enforceable obligation of a superior or unrelated governmental entity, it will be included in the computation of securities owned that are issued by such governmental entity. When a security is backed by the enforceable obligation of a superior or unrelated non-governmental entity (other than a bond insurer), it will also be included in the computation of securities owned that are issued by such non-governmental entity. Where a security is guaranteed by a governmental entity or some other facility, such as a bank guarantee or letter of credit, such a guarantee or letter of credit would be considered a separate security and would be treated as an issue of such government, other entity or bank. When a municipal security is insured by bond insurance, it shall not be considered a security that is issued or guaranteed by the insurer; instead, the issuer of such municipal security will be determined in accordance with the principles set forth above. The foregoing restrictions do not limit the percentage of the Trust’s assets that may be invested in municipal securities insured by any given insurer.

The Trust is currently classified as a diversified fund under the Investment Company Act. This means that the Trust may not purchase securities of an issuer (other than (i) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities and (ii) securities of other investment companies) if, with respect to 75% of its total assets, (a) more than 5% of the Trust’s total assets would be invested in securities of that issuer or (b) the Trust would hold more than 10% of the outstanding voting securities of that issuer. With respect to the remaining 25% of its total assets, the Trust can invest more than 5% of its assets in one issuer. Under the Investment Company Act, the Trust cannot change its classification from diversified to non-diversified without shareholder approval (including class approval by preferred shareholders, if any).

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

Make any short sale of securities except in conformity with applicable laws, rules and regulations and unless after giving effect to such sale, the market value of all securities sold short does not exceed 25% of the value of the Trust’s total assets and the Trust’s aggregate short sales of a particular class of securities does not exceed 25% of the then-outstanding securities of that class. The Trust may also make short sales “against the box” without respect to such limitations. In this type of short sale, at the time of the sale, the Trust owns or has the immediate and unconditional right to acquire at no additional cost the identical security.

Purchase securities of open-end or closed-end investment companies except in compliance with the Investment Company Act or any regulations promulgated or exemptive relief obtained thereunder.

Purchase securities of companies for the purpose of exercising control.

Unless otherwise indicated, all limitations under the Trust’s fundamental or non-fundamental investment restrictions apply only at the time that a transaction is undertaken. Any change in the percentage of the Trust’s assets invested in certain securities or other instruments resulting from market fluctuations or other changes in

S-4

the Trust’s total assets will not require the Trust 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.

In addition, to comply with Federal tax requirements for qualification as a “regulated investment company,” the Trust’s investments will be limited in a manner such that at the close of each quarter of each taxable year, (a) no more than 25% of the value of the Trust’s total assets are invested in the securities (other than United States government securities or securities of other regulated investment companies) of a single issuer or two or more issuers controlled by the Trust and engaged in the same, similar or related trades or businesses and (b) with regard to at least 50% of the Trust’s total assets, no more than 5% of its total assets are invested in the securities (other than United States government securities or securities of other regulated investment companies) of a single issuer and such securities do not represent more than 10 percent of the voting securities of such issuer. These tax-related limitations may be changed by the trustees to the extent appropriate in light of changes to applicable tax requirements.

If the Trust offers preferred shares, it may apply for ratings for such preferred shares from Moody’s, S&P and/or Fitch. In order to obtain and maintain the required ratings, the Trust may be required to comply with investment quality, diversification and other guidelines established by Moody’s, S&P and/or Fitch. Such guidelines may be more restrictive than the restrictions set forth above. The Trust does not anticipate that such guidelines would have a material adverse effect on the Trust’s holders of common shares or its ability to achieve its investment objectives. The Trust presently anticipates that any preferred shares issued would be initially given the highest ratings by Moody’s (Aaa) or by S&P or Fitch (AAA), but no assurance can be given that such ratings will be obtained. No minimum rating is required for the issuance of preferred shares by the Trust. Moody’s, S&P and Fitch receive fees in connection with their ratings issuances.

INVESTMENT POLICIES AND TECHNIQUES

The following information supplements the discussion of the Trust’s investment objectives, policies and techniques that are described in the Prospectus.

Portfolio Investments

Municipal Securities

Municipal security bonds are either general obligation or revenue bonds and typically are issued to finance public projects, such as roads or public buildings, to pay general operating expenses or to refinance outstanding debt. Municipal security 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.

Issuers of securities rated Ba/BB or below are regarded as having current capacity to make principal and interest payments but are subject to business, financial or economic conditions which could adversely affect such payment capacity. Municipal securities rated Baa/BBB or better are considered “investment grade” securities; municipal securities rated Baa are considered medium grade obligations which lack outstanding investment characteristics and have speculative characteristics, while municipal securities rated BBB are regarded as having adequate capacity to pay principal and interest. Municipal securities rated AAA in which the Trust may invest may have been so rated on the basis of the existence of insurance guaranteeing the timely payment, when due, of all principal and interest. Municipal securities rated below investment grade quality (Ba/BB or lower) are obligations of issuers that are considered predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal according to the terms of the obligation and, therefore, carry greater investment risk, including the possibility of issuer default and bankruptcy and increased market price volatility. Municipal securities rated below investment grade tend to be less marketable than higher-quality securities because the

S-5

market for them is less broad. The market for unrated municipal securities is even narrower. During periods of thin trading in these markets, the spread between bid and ask prices is likely to increase significantly and the Trust may have greater difficulty selling its portfolio securities. The Trust will be more dependent on the research and analysis of the Advisor.

A general description of Moody’s, S&P’s and Fitch’s ratings of municipal securities is set forth in Appendix A hereto. The ratings of Moody’s, S&P and Fitch represent their opinions as to the quality of the municipal securities they rate. It should be emphasized, however, that ratings are general and are not absolute standards of quality. Consequently, municipal securities with the same maturity, coupon and rating may have different yields while obligations of the same maturity and coupon with different ratings may have the same yield.

The Trust will opportunistically manage the maturity and/or duration of its securities and the average weighted maturity and/or duration may be shortened or lengthened from time to time depending on market conditions. As a result, the Trust’s portfolio at any given time may include both long-term and intermediate-term municipal securities. Moreover, during temporary defensive periods (e.g., times when, in the Advisor’s opinion, temporary imbalances of supply and demand or other temporary dislocations in the municipal securities market adversely affect the price at which long-term or intermediate-term municipal securities are available), and in order to keep cash on hand fully invested, including the period during which the net proceeds of the offering of common shares or securities in connection with leverage, if any, are being invested, the Trust may invest any percentage of its assets in short-term investments including high quality, short-term securities which may be either tax-exempt or taxable and securities of other open- or closed-end investment companies that invest primarily in municipal securities of the type in which the Trust may invest directly.

Obligations of issuers of municipal securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Bankruptcy Reform Act of 2005. In addition, the obligations of such issuers may become subject to the laws enacted in the future by Congress, state legislatures or referenda extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon municipalities to levy taxes. There is also the possibility that, as a result of legislation or other conditions, the power or ability of any issuer to pay, when due, the principal of and interest on its municipal securities may be materially affected.

Short-Term Taxable Fixed Income Securities

For temporary defensive purposes or to keep cash on hand fully invested, the Trust may invest up to 100% of its Managed Assets in cash equivalents and short-term taxable fixed income securities. The Trust may also invest in these instruments to achieve its investment objectives. Short-term taxable fixed income investments are defined to include, without limitation, the following:

(1) U.S. Government securities, including bills, notes and bonds differing as to maturity and rates of interest that are either issued or guaranteed by the U.S. Treasury or by U.S. Government agencies or instrumentalities. U.S. Government securities include securities issued by (a) the Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, and 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 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

S-6

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 Trust may not be fully insured by the Federal Deposit Insurance Corporation.

(3) Repurchase agreements, which involve purchases of debt securities. At the time the Trust 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 Trust 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 Trust to invest temporarily available cash. The Trust 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 Trust may invest. Repurchase agreements may be considered loans to the seller, collateralized by the underlying securities. The risk to the Trust 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 Trust 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 Trust 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 Trust. If the seller were to be subject to a Federal bankruptcy proceeding, the ability of the Trust 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 Trust and a corporation. There is no secondary market for such notes. However, they are redeemable by the Trust 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 Trust’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

For temporary defensive purposes or to keep cash on hand fully invested, the Trust may invest up to 100% of its Managed Assets in cash equivalents and short-term tax-exempt fixed income securities. The Trust may also invest in these instruments to achieve its investment objectives. Short-term tax-exempt fixed income securities are securities that are exempt from regular Federal income tax and mature within three years or less from the date of issuance. Short-term tax-exempt fixed income securities are defined to include, without limitation, the following:

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.

S-7

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

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

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

While the various types of notes described above as a group represent the major portion of the tax-exempt note market, other types of notes are available in the marketplace and the Trust 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.

Strategic Transactions and Other Management Techniques

Consistent with its investment objectives and policies set forth herein, the Trust may also enter into certain hedging and risk management transactions or transactions to enhance total return. In particular, the Trust may purchase and sell futures contracts, exchange-listed and over-the-counter put and call options on securities, financial indices and futures contracts, forward foreign currency contracts, and may enter into various interest rate transactions (collectively, “Strategic Transactions”). Strategic Transactions may be used to attempt to protect against possible changes in the market value of the Trust’s portfolio resulting from fluctuations in the debt securities markets and changes in interest rates, to protect the Trust’s unrealized gains in the value of its portfolio securities, to facilitate the sale of such securities for investment purposes and to establish a position in the securities markets as a temporary substitute for purchasing particular securities. Any or all of these Strategic Transactions may be used at any time whether for hedging and risk management or to enhance total return. There is no particular strategy that requires use of one technique rather than another. Use of any Strategic Transaction is a function of market conditions. The Strategic Transactions that the Trust may use are described below. The ability of the Trust to hedge them 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.

Interest Rate Transactions. The Trust may enter into interest rate swaps and purchase or sell interest rate caps and floors 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 Trust anticipates purchasing at a later date. The Trust intends to use these transactions for duration and risk management purposes and not as a speculative investment. The Trust will not sell interest rate caps or floors that it does not own. Interest rate swaps involve the exchange by the Trust with another party of their respective commitments to pay or receive interest, e.g., an exchange of floating rate payments for fixed rate payments with respect to a notional

S-8

amount of principal. The purchase of an interest rate cap entitles the purchaser, to the extent that a specified index exceeds a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate cap. The purchase of an interest rate floor entitles the purchaser, to the extent that a specified index falls below a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate floor.

The Trust may enter into interest rate swaps, caps and floors on either an asset-based or liability-based basis, depending on whether it is offsetting volatility with respect to its assets or liabilities, and will usually enter into interest rate swaps on a net basis, i.e., the two payment streams are netted out, with the Trust receiving or paying, as the case may be, only the net amount of the two payments on the payment dates. In as much as these Strategic Transactions are entered into for good faith risk management purposes, the Advisor and the Trust believe such obligations do not constitute senior securities and, accordingly, will not treat them as being subject to its borrowing restrictions. The Trust will accrue the net amount of the excess, if any, of the Trust’s obligations over its entitlements with respect to each interest rate swap on a daily basis and will designate on its books and records with a custodian an amount of cash or liquid high grade securities having an aggregate net asset value at all times at least equal to the accrued excess. The Trust will not enter into any interest rate swap, cap or floor transaction unless the unsecured senior debt or the claims-paying ability of the other party thereto is rated in the highest rating category of at least one nationally recognized statistical rating organization at the time of entering into such transaction. If there is a default by the other party to such a transaction, the Trust will have contractual remedies pursuant to the agreements related to the transaction. The swap market has grown substantially in recent years with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. Caps and floors are more recent innovations for which standardized documentation has not yet been developed and, accordingly, they are less liquid than swaps.

Futures Contracts and Options on Futures Contracts. In connection with its hedging and other risk management strategies, the Trust may also enter into contracts for the purchase or sale for future delivery (“futures contracts”) of debt securities, aggregates of debt securities or indices or prices thereof, other financial indices and U.S. Government debt securities or options on the above. The Trust primarily intends to engage in such transactions for bona fide hedging or risk management and other portfolio management purposes.

Calls on Securities, Indices and Futures Contracts. In order to enhance income or reduce fluctuations on net asset value, the Trust may sell or purchase call options (“calls”) on municipal securities and indices based upon the prices of futures contracts and debt securities that are traded on U.S. and foreign securities exchanges and in the over-the-counter markets. A call option gives the purchaser of the option the right to buy, and obligates the seller to sell, the underlying security, futures contract or index at the exercise price at any time or at a specified time during the option period. All such calls sold by the Trust must be “covered” as long as the call is outstanding (i.e., the Trust must own the instrument subject to the call or other securities or assets acceptable for applicable segregation and coverage requirements). A call sold by the Trust exposes the Trust during the term of the option to possible loss of opportunity to realize appreciation in the market price of the underlying security, index or futures contract and may require the Trust to hold an instrument which it might otherwise have sold. The purchase of a call gives the Trust the right to buy a security, futures contract or index at a fixed price. Calls on futures on municipal securities must also be covered by assets or instruments acceptable under applicable segregation and coverage requirements.

Puts on Securities, Indices and Futures Contracts. As with calls, the Trust may purchase put options (“puts”) that relate to municipal securities (whether or not it holds such securities in its portfolio), indices or futures contracts. For the same purposes, the Trust may also sell puts on municipal securities, indices or futures contracts on such securities. In selling puts, there is a risk that the Trust may be required to buy the underlying security at a price higher than the current market price.

Credit Derivatives. The Trust may engage in credit derivative transactions. There are two broad categories of credit derivatives: default price risk derivatives and market spread derivatives. Default price risk derivatives are linked to the price of reference securities or loans after a default by the issuer or borrower, respectively. Market spread derivatives are based on the risk that changes in market factors, such as credit spreads, can cause a decline

S-9

in the value of a security, loan or index. There are three basic transactional forms for credit derivatives: swaps, options and structured instruments. The use of credit derivatives is a highly specialized activity which involves strategies and risks different from those associated with ordinary portfolio security transactions. If the Advisor is incorrect in its forecasts of default risks, market spreads or other applicable factors, the investment performance of the Trust would diminish compared with what it would have been if these techniques were not used. Moreover, even if the Advisor is correct in its forecasts, there is a risk that a credit derivative position may correlate imperfectly with the price of the asset or liability being hedged. There is no limit on the amount of credit derivative transactions that may be entered into by the Trust. The Trust’s risk of loss in a credit derivative transaction varies with the form of the transaction. For example, if the Trust purchases a default option on a security, and if no default occurs with respect to the security, the Trust’s loss is limited to the premium it paid for the default option. In contrast, if there is a default by the grantor of a default option, the Trust’s loss will include both the premium that it paid for the option and the decline in value of the underlying security that the default option hedged.

Municipal Market Data Rate Locks. The Trust may purchase and sell Municipal Market Data Rate Locks (“MMD Rate Locks”). An MMD Rate Lock permits the Trust 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. The Trust will ordinarily use these transactions as a hedge or for duration or risk management although it is permitted to enter into them to enhance income or gain. An MMD Rate Lock is a contract between the Trust and an MMD Rate Lock 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 Trust buys an MMD Rate Lock 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 Trust 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 Trust 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 entering into MMD Rate Locks, there is a risk that municipal yields will move in the direction opposite of the direction anticipated by the Trust. The Trust will not enter into MMD Rate Locks if, as a result, more than 50% of its total assets would be required to cover its potential obligations under its hedging and other investment transactions.

New Products. The financial markets continue to evolve and financial products continue to be developed. The Trust 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 Trust currently is not subject.

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

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

Short Sales

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

S-10

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

The Trust’s obligation to replace the borrowed security will be secured by collateral deposited with the broker-dealer, usually cash, U.S. Government securities or other liquid securities. Depending on arrangements made with the broker-dealer from which it borrowed the security regarding payment over of any payments received by the Trust on such security, the Trust may not receive any payments (including interest) on its collateral deposited with such broker-dealer.

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

The Trust will not make a short sale if, after giving effect to such sale, the market value of all securities sold short exceeds 25% of the value of its total assets or the Trust’s aggregate short sales of a particular class of securities exceeds 25% of the outstanding securities of that class. The Trust may also make short sales “against the box” without respect to such limitations. In this type of short sale, at the time of the sale, the Trust owns or has the immediate and unconditional right to acquire at no additional cost the identical security.

The Trust must comply with Rule 18f-4 under the Investment Company Act with respect to its short sale borrowings, which are considered derivatives transactions under the Rule. See “Additional Risk Factors—Risk Factors in Strategic Transactions and Derivatives—Rule 18f-4 Under the Investment Company Act” below.

Short sales are also subject to certain SEC regulations and certain European Union and United Kingdom regulations (under which there are restrictions on net short sales in certain securities). If the SEC or regulatory authorities in other jurisdictions were to adopt additional restrictions regarding short sales, they could restrict the Trust’s ability to engage in short sales in certain circumstances, and the Trust may be unable to execute its investment strategy as a result. In response to market events, the SEC and regulatory authorities in other jurisdictions may adopt (and in certain cases, have adopted) bans or other restrictions on short sales of certain securities or on derivatives and other hedging instruments used to achieve a similar economic effect. Such bans or other restrictions may make it impossible for the Trust to execute certain investment strategies and may have a material adverse effect on the Trust’s ability to generate returns.

Environmental, Social and Governance (“ESG”) Integration

Although the Trust does not seek to implement a specific sustainability objective, strategy or process unless disclosed in the Prospectus, Trust management will consider ESG factors as part of the investment process for the Trust. Trust management views ESG integration as the practice of incorporating financially material ESG data or information into investment processes with the objective of enhancing risk-adjusted returns. These ESG considerations will vary depending on a fund’s particular investment strategies and may include consideration of third-party research as well as consideration of proprietary research of the Advisor across the ESG risks and opportunities regarding an issuer. The ESG characteristics utilized in the Trust’s investment process are anticipated to evolve over time and one or more characteristics may not be relevant with respect to all issuers that are eligible for investment.

Certain of these considerations may affect the Trust’s exposure to certain companies or industries. While Trust management views ESG considerations as having the potential to contribute to the Trust’s long-term performance, there is no guarantee that such results will be achieved.

S-11

OTHER INVESTMENT POLICIES AND TECHNIQUES

Restricted and Illiquid Investments

The Trust 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 Trust’s assets in illiquid investments may restrict the ability of the Trust 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 Trust’s operations require cash, such as when the Trust pays dividends, and could result in the Trust borrowing to meet short-term cash requirements or incurring capital losses on the sale of illiquid investments.

The Trust 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 Trust 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 Trust are required to be registered under the securities laws of one or more jurisdictions before being resold, the Trust 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 Trust 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 Trust 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 Trust’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 Trust may obtain access to material nonpublic information, which may restrict the Trust’s ability to conduct portfolio transactions in such securities.

Repurchase Agreements

As temporary investments, the Trust may invest in repurchase agreements. A repurchase agreement is a contractual agreement whereby the seller of securities agrees to repurchase the same security at a specified price on a future date agreed upon by the parties. The agreed-upon repurchase price determines the yield during the Trust’s holding period. Repurchase agreements are considered to be loans collateralized by the underlying security that is the subject of the repurchase contract. The Trust will only enter into repurchase agreements with registered securities dealers or domestic banks that, in the opinion of the Advisor, present minimal credit risk. The risk to the Trust 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 Trust 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 Trust may be delayed or limited. The Advisor will monitor the value of the collateral at the time the transaction is entered into and at all times subsequent during the term of the

S-12

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.

Securities Lending

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

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

The Trust conducts its securities lending pursuant to an exemptive order from the SEC permitting it to lend portfolio securities to borrowers affiliated with the Trust and to retain an affiliate of the Trust as lending agent. To the extent that the Trust engages in securities lending, BlackRock Investment Management, LLC (“BIM”) acts as securities lending agent for the Trust, subject to the overall supervision of the Advisor, pursuant to a written agreement (the “Securities Lending Agency Agreement”). BIM administers the lending program in accordance with guidelines approved by the Board.

To the extent the Trust engages in securities lending, the Trust retains a portion of the securities lending income and remits the remaining portion to BIM as compensation for its services as securities lending agent. Securities lending income is generally equal to the total of income earned from the reinvestment of cash collateral (and excludes collateral investment fees as defined below), and any fees or other payments to and from borrowers of securities. As securities lending agent, BIM bears all operational costs directly related to securities lending. The Trust is responsible for fees in connection with the investment of cash collateral received for securities on loan in a money market fund managed by BlackRock (the “collateral investment fees”); however, the securities lending agent has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees the Trust bears to an annual rate of 0.04%. Such money market fund shares will not be subject to a sales load, redemption fee, distribution fee or service fee.

To the extent that the Trust invests cash collateral in a non-government money market fund, the Trust may be subject to a discretionary liquidity fee of up to 2% on all redemptions. Discretionary liquidity fees may be imposed or terminated at any time at the discretion of the board of directors of the money market fund, or its delegate, if it is determined that such fee would be, or would not be, respectively, in the best interest of the money market fund. Additionally, the Trust will be subject to a mandatory liquidity fee if the money market fund’s total net redemptions on a single day exceed 5% of the money market fund’s net assets, unless the liquidity costs are de minimis (i.e., less than one basis point (0.01%)). The money market fund will determine the size of the mandatory liquidity fee by making a good faith estimate of certain costs the money market fund would incur if it were to sell a pro rata amount of each security in the portfolio to satisfy the amount of net redemptions on that day. There is no limit to the size of a mandatory liquidity fee. If the money market fund cannot estimate the costs of selling a pro rata amount of each portfolio security in good faith and supported by data, it is required

S-13

to apply a default liquidity fee of 1% on the value of shares redeemed on that day. The imposition of any such discretionary or mandatory liquidity fee would reduce the Trust’s returns on securities lending.

Under the securities lending program, the Trust is categorized into a specific asset class. The determination of the Trust’s asset class category (fixed income, domestic equity, international equity, or fund of funds), each of which may be subject to a different fee arrangement, is based on a methodology agreed to between the Trust and BIM.

Pursuant to the current securities lending agreement: (i) if the Trust were to engage in securities lending, the Trust retains 82% of securities lending income (which excludes collateral investment expenses), and (ii) this amount can never be less than 70% of the sum of securities lending income plus collateral investment expenses.

In addition, commencing the business day following the date that the aggregate securities lending income earned across the BlackRock Fixed-Income Complex in a calendar year exceeds specified thresholds, the Trust, pursuant to the current securities lending agreement, will receive for the remainder of that calendar year securities lending income as follows: (i) if the Trust were to engage in securities lending, 85% of securities lending income (which excludes collateral investment expenses); and (ii) this amount can never be less than 70% of the sum of securities lending income plus collateral investment expenses.

High Yield Securities

The Trust may invest up to 20% of its Managed Assets in securities rated below investment grade, such as those rated Ba or below by Moody’s or BB or below by S&P or Fitch or securities comparably rated by other rating agencies or in unrated securities determined by the Advisor to be of comparable quality. Securities rated Ba and below by Moody’s and Fitch are judged to have speculative elements, their future cannot be considered as well assured and often the protection of interest and principal payments may be very moderate. Securities rated BB by S&P are regarded as having predominantly speculative characteristics and, while such obligations have less near-term vulnerability to default than other speculative grade debt, they face major ongoing uncertainties or exposure to adverse business, financial or economic conditions, which could lead to inadequate capacity to meet timely interest and principal payments.

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

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

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

The ratings of Moody’s, S&P 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

S-14

also will independently evaluate these securities and the ability for the issuers of such securities to pay interest and principal. To the extent that the Trust invests in lower grade securities that have not been rated by a rating agency, the Trust’s ability to achieve its investment objectives will be more dependent on the Advisor’s credit analysis than would be the case when the Trust invests in rated securities.

ADDITIONAL RISK FACTORS

Risk Factors in Strategic Transactions and Derivatives

The Trust’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. There are significant risks that apply generally to derivatives transactions, including:

•

Correlation Risk—the risk that a derivatives transaction counterparty will be unable or unwilling to make payments or otherwise honor its obligations to the Trust and the related risks of having concentrated exposure to such a counterparty. In particular, derivatives traded in OTC markets often are not guaranteed by an exchange or clearing corporation and often do not require payment of margin, and to the extent that the Trust has unrealized gains in such instruments or has deposited collateral with its counterparties the Trust is at risk that its counterparties will become bankrupt or otherwise fail to honor their obligations. The Trust will typically attempt to minimize counterparty risk by engaging in OTC derivatives transactions only with creditworthy entities that have substantial capital or that have provided the Trust with a third-party guaranty or other credit support. When the Trust enters into a derivatives transaction that is centrally cleared (whether mandatorily or voluntarily), the Trust is subject to the credit risk of the clearing house and the clearing member through which it holds its cleared position. Credit risk of market participants with respect to derivatives that are centrally cleared is concentrated in a few clearing houses and increasingly fewer clearing members. It is not clear how an insolvency proceeding of a clearing house would be conducted and what impact an insolvency of a clearing house would have on the financial system. Also, the Trust will not be fully protected in the event of the bankruptcy of the Trust’s clearing member because the Trust would be limited to recovering only a pro rata share of the funds held by the clearing member on behalf of customers by account class for cleared derivatives. Although a clearing member is required to segregate assets from customers with respect to cleared derivatives positions from the clearing member’s proprietary assets, if a clearing member does not comply with the applicable regulations, or in the event of fraud or misappropriation of customer assets by a clearing member, the Trust could have only an unsecured creditor claim in an insolvency of the clearing member with respect to the assets held by the clearing member.

Counterparty Risk—the risk that the counterparty in a derivative transaction will be unable to honor its financial obligation to the Trust and the related risks of having concentrated exposure to such a counterparty. In particular, derivatives traded in OTC markets often are not guaranteed by an exchange or clearing corporation and often do not require payment of margin, and to the extent that the Trust has unrealized gains in such instruments or has deposited collateral with its counterparties the Trust is at risk that its counterparties will become bankrupt or otherwise fail to honor their obligations. The Trust will typically attempt to minimize counterparty risk by engaging in OTC derivatives transactions only with creditworthy entities that have substantial capital or that have provided the Trust with a third-party guaranty or other credit support.

•

Credit Risk—the risk that the reference entity in a credit default swap or similar derivative will not be able to honor its financial obligations.

•

Currency Risk—the risk that changes in the exchange rate between two currencies will adversely affect the value (in U.S. dollar terms) of an investment.

•

Illiquidity Risk—the risk that certain securities or instruments may be difficult or impossible to sell at the time or at the price desired by the Trust in connection with payments of margin, collateral, or settlement payments. There can be no assurance that the Trust will be able to unwind or offset a derivative at its desired price, in a secondary market or otherwise. It may, therefore, not be possible for the Trust to unwind its position in a derivative without incurring substantial losses (if at all). Certain OTC derivatives, including swaps and OTC options, involve substantial illiquidity risk. Illiquidity may also make it more difficult for the Fund to ascertain the market value for such derivatives. The Trust will, therefore, acquire illiquid OTC derivatives (i) if the agreement pursuant to which the instrument is purchased contains a formula price at which the instrument may be terminated or sold, or (ii) for which the Advisor anticipates the Trust can receive on each business day at least two independent bids or offers, unless a quotation from only one dealer is available, in which case that dealer’s quotation may be used. 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, the liquidity of a market in an exchange-traded derivative contract may be adversely affected by “daily price fluctuation limits” established by the exchanges which limit the amount of fluctuation in an exchange-traded 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 positions. Prices have in the past moved to the daily limit on a number of consecutive trading days with little to no trading. If it is not possible to close an open derivative position entered into by the Trust, the Trust would continue to be required to make daily cash payments of variation margin in the event of adverse price movements. In such a situation, if the Trust has insufficient cash, it may have to sell portfolio securities to meet daily variation margin requirements at a time when it may be disadvantageous to do so.

•

Index Risk—if the derivative is linked to the performance of an index, it will be subject to the risks associated with changes in that index. If the index changes, the Trust could receive lower interest payments or experience a reduction in the value of the derivative to below the price that the Trust paid for such derivative.

•

Legal Risk—the risk of insufficient documentation, insufficient capacity or authority of counterparty, or legality or enforceability of a contract.

•

Leverage Risk—the risk that the Trust’s derivatives transactions can magnify the Trust’s gains and losses. Relatively small market movements may result in large changes in the value of a derivatives position and can result in losses that greatly exceed the amount originally invested.

•

Market Risk—the risk that changes in the value of one or more markets or changes with respect to the value of the underlying asset will adversely affect the value of a derivative. In the event of an adverse movement, the Trust may be required to pay substantial additional margin to maintain its position or the Trust’s returns may be adversely affected.

•

Operational Risk—the risk related to potential operational issues, including documentation issues, settlement issues, systems failures, inadequate controls and human error.

•

Valuation Risk—the risk that valuation sources for a derivative will not be readily available in the market. This is possible especially in times of market distress, since many market participants may be reluctant to purchase complex instruments or quote prices for them.

•

Volatility Risk—the risk that the value of derivatives will fluctuate significantly within a short time period.

When a derivative is used as a hedge against a position that the Trust holds, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can

S-16

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 Trust’s hedging transactions will be effective. The Trust 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 Trust’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 Trust to sell or otherwise close a derivatives position could expose the Trust to losses and could make derivatives more difficult for the Trust to value accurately.

When engaging in a hedging transaction, the Trust 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 Trust from achieving the intended hedge or expose the Trust to a risk of loss. The Trust 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 not foresee the occurrence of the risk. It may not be possible for the Trust to hedge against a change or event at attractive prices or at a price sufficient to protect the assets of the Trust from the decline in value of the portfolio positions anticipated as a result of such change. In addition, it may not be possible to hedge at all against certain risks.

If the Trust 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 Trust.

The Trust 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 Trust 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 Trust’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 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 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 Trust 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.

S-17

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 Trust 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 Trust 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 Trust 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 Trust. As a result, the Trust’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 Trust. The correlation may be affected by disparities in the average maturity, ratings, geographical mix or structure of the Trust’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 Trust 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 Trust 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 Trust 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 Trust would continue to be required to make daily cash payments of variation margin. In such situations, if the Trust 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 Trust’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 Trust or such rates move in a direction opposite to that anticipated, the Trust 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 Trust’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 Trust of margin deposits in the event of bankruptcy of a broker with which the Trust has an open position in a financial futures contract. Because the Trust will engage in the purchase and sale of futures contracts for hedging purposes or to seek to enhance the Trust’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 Trust or decreases in the price of securities the Trust intends to acquire.

S-18

The amount of risk the Trust 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 Trust’s use of Currency Instruments to effect hedging strategies is intended to reduce the volatility of the NAV of the Trust’s common shares, the NAV of the Trust’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 Trust’s hedging strategies will be ineffective. To the extent that the Trust hedges against anticipated currency movements that do not occur, the Trust may realize losses and decrease its total return as the result of its hedging transactions. Furthermore, the Trust 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 Trust 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 Trust 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 Trust 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 Trust 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 Trust 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 Trust 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 Trust of any profit potential or force the Trust to cover its commitments for resale, if any, at the then market price and could result in a loss to the Trust.

The Trust 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 Trust 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 Trust’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 Trust 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 Trust is engaging in proxy hedging. The Trust 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 Trust has or

S-19

in which the Trust expects to have portfolio exposure. For example, the Trust may hold both Canadian government bonds and Japanese government bonds, and the Advisor may believe that Canadian dollars will deteriorate against Japanese yen. The Trust 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 Trust 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 Trust 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 Trust 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 Trust 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 Trust 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 Trust 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 Trust 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 Trust 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 Trust 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 Trust 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 Trust has unrealized gains in such instruments or has deposited collateral with its counterparties the Trust is at risk that its counterparties will become bankrupt or otherwise fail to honor its obligations.

S-20

Rule 18f-4 Under the Investment Company Act. Rule 18f-4 under the Investment Company Act permits the Trust to enter into Derivatives Transactions (as defined below) and certain other transactions notwithstanding the restrictions on the issuance of “senior securities” under Section 18 of the Investment Company Act. Section 18 of the Investment Company Act, among other things, prohibits closed-end funds, including the Trust, from issuing or selling any “senior security” representing indebtedness (unless the fund maintains 300% “asset coverage”) or any senior security representing stock (unless the fund maintains 200% “asset coverage”).

Under Rule 18f-4, “Derivatives Transactions” include the following: (1) any swap, security-based swap (including a contract for differences), futures contract, forward contract, option (excluding purchased options), any combination of the foregoing, or any similar instrument, under which the Trust is or may be required to make any payment or delivery of cash or other assets during the life of the instrument or at maturity or early termination, whether as margin or settlement payment or otherwise; (2) any short sale borrowing; (3) reverse repurchase agreements and similar financing transactions (e.g., recourse and non-recourse tender option bonds, and borrowed bonds), if the Trust elects to treat all of these transactions as Derivatives Transactions under Rule 18f-4; and (4) when-issued or forward-settling securities (e.g., firm and standby commitments, including to-be-announced (“TBA”) commitments, and dollar rolls) and non-standard settlement cycle securities, unless such transactions meet the Delayed-Settlement Securities Provision (as defined in the prospectus under “The Trust’s Investments—Description of Municipal Securities—When-Issued Securities, Delayed Delivery Securities and Forward Commitments”).

Unless the Trust is relying on the Limited Derivatives User Exception (as defined below), the Trust must comply with Rule 18f-4 with respect to its Derivatives Transactions. Rule 18f-4, among other things, requires the Trust to adopt and implement a comprehensive written derivatives risk management program (“DRMP”) and comply with a relative or absolute limit on fund leverage risk calculated based on value-at-risk (“VaR”). The DRMP is administered by a “derivatives risk manager,” who is appointed by the Trust’s Board of Trustees (the “Board”), including a majority of the Trustees who are not “interested persons” (as defined in the Investment Company Act) (the “Independent Trustees”), and periodically reviews the DRMP and reports to the Board.

Rule 18f-4 provides an exception from the DRMP, VaR limit and certain other requirements if the Trust’s “derivatives exposure” is limited to 10% of its net assets (as calculated in accordance with Rule 18f-4) and the Trust adopts and implements written policies and procedures reasonably designed to manage its derivatives risks (the “Limited Derivatives User Exception”).

Many OTC derivatives dealers are required to register with the CFTC as “swap dealers” and/or with the SEC as “security-based swap dealers”. Registered swap dealers and security-based swap dealers are subject to various regulatory requirements, including, but not limited to, margin, recordkeeping, reporting, transparency, position limits, limitations on conflicts of interest, business conduct standards, minimum capital requirements and other regulatory requirements, which indirectly impact the funds that enter into transactions with them.

The CFTC requires that certain interest rate swaps and certain credit default swaps must be executed in regulated markets and be submitted for clearing to regulated clearinghouses. The SEC is also expected to impose similar requirements on certain security-based derivatives in the future. OTC derivatives trades submitted for clearing are subject to minimum initial and variation margin requirements set by the relevant clearinghouse, as well as margin requirements mandated by the CFTC, SEC and/or federal prudential regulators. In addition, futures commission merchants (“FCMs”), who act as clearing members on behalf of customers for cleared OTC derivatives and futures contracts, also have discretion to increase the Trust’s margin requirements for these transactions beyond any regulatory and clearinghouse minimums subject to any restrictions on such discretion in the documentation between the FCM and the customer. These regulatory requirements may make it more difficult and costly for the Trust to enter into highly tailored or customized transactions, potentially rendering certain investment strategies impossible or not economically feasible. If the Trust decides to execute and clear cleared OTC derivatives and/or futures contracts through execution facilities, exchanges or clearinghouses, either indirectly through an executing broker, clearing member FCM or as a direct member, the Trust would be required to comply with the rules of the execution facility, exchange or clearinghouse and other applicable law.

S-21

With respect to cleared OTC derivatives and futures contracts and options on futures, the Trust will not face a clearinghouse directly but rather will do so through a FCM that is registered with the CFTC and/or SEC and that acts as a clearing member. The Trust may face the indirect risk of the failure of another clearing member customer to meet its obligations to its clearing member. Such scenario could arise due to a default by the clearing member on its obligations to the clearinghouse simultaneously with a customer’s failure to meet its obligations to the clearing member.

Clearing member FCMs are required to post initial margin to the clearinghouses through which they clear their customers’ cleared OTC derivatives and futures contracts, instead of using such initial margin in their businesses, as was widely permitted for OTC derivatives before the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (“Dodd-Frank”). While an FCM may require its customer to post initial margin in excess of clearinghouse requirements, and certain clearinghouses may share a portion of their earnings on initial margin with their clearing members, some portion of the initial margin that is passed through to the clearinghouse does not generate earnings for the FCM. The inability of FCMs to earn the same levels of returns on initial margin for cleared OTC derivatives as they could earn with respect to non-cleared OTC derivatives may cause FCMs to charge higher fees, or provide less favorable pricing on cleared OTC derivatives than swap dealers will provide for non-cleared OTC derivatives. Furthermore, customers, including the Trust, are subject to additional fees payable to FCMs with respect to cleared OTC derivatives, which may raise the cost to the Trust of clearing as compared to trading non-cleared OTC derivatives bilaterally.

With respect to uncleared swaps, registered swap dealers and security-based swap dealers are required to exchange variation margin with the Trust and may be required by applicable regulations to collect (and in some cases exchange) initial margin with the Trust. Both initial and variation margin may be comprised of cash and/or securities, subject to applicable regulatory haircuts and other restrictions. Shares of investment companies (other than certain money market funds) may not be posted as collateral under applicable regulations.

The CFTC, certain foreign regulators, and many futures exchanges have established (and continue to evaluate and monitor) speculative position limits (“position limits”) on the maximum speculative position which any person, or group of persons acting in concert, may hold or control in particular contracts. In addition, U.S. federal position limits apply to swaps that are economically equivalent to futures contracts on certain agricultural, metals and energy commodities. All positions owned or controlled by the same person or entity, even if in different accounts, must be aggregated for purposes of complying with the speculative limits. Thus, even if the Trust does not intend to exceed applicable position limits, it is possible that different clients managed by the Advisor and its affiliates may be aggregated for this purpose. Therefore, the trading decisions of the Advisor may have to be modified and positions held by the Trust liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of the Trust. A violation of position limits could also lead to regulatory action materially adverse to the Trust’s investment strategy. The Trust may also be affected by other regimes, including those of the European Union and United Kingdom, and trading venues that impose position limits on commodity derivative contracts.

Additional Regulation of Derivatives. Regulatory bodies outside the U.S. have also passed, proposed, or may propose in the future, legislation similar to Dodd-Frank or other legislation that could increase the costs of participating in, or otherwise adversely impact the liquidity of, participating in the commodities markets. For example, the European Market Infrastructure Regulation (Regulation (EU) No 648/2012) (“EMIR”) introduced certain requirements in respect of OTC derivatives including:(i) the mandatory clearing of OTC derivative contracts declared subject to the clearing obligation; (ii) risk mitigation techniques in respect of uncleared OTC derivative contracts, including the mandatory margining of uncleared OTC derivative contracts; and (iii) reporting and recordkeeping requirements in respect of all derivatives contracts. By way of further example, the European Union Markets in Financial Instruments Directive (Directive 2014/65/EU) and Markets in Financial Instruments Regulation (Regulation (EU) No 600/2014) (together “MiFID II”), which have applied since January 3, 2018, govern the provision of investment services and activities in relation to, as well as the organized trading of, financial instruments such as shares, bonds, units in collective investment schemes and derivatives. In particular, MiFID II requires European Union Member States to apply position limits to the size of a net position

S-22

a person can hold at any time in commodity derivatives traded on European Union trading venues and in “economically equivalent” OTC contracts. If the requirements of EMIR and MiFID II apply, the cost of derivatives transactions is expected to increase.

In addition, regulations adopted by global prudential regulators that are now in effect require certain prudentially regulated entities and certain of their affiliates and subsidiaries (including swap dealers) to include in their derivatives contracts and certain other financial contracts, terms that delay or restrict the rights of counterparties (such as the Trust) to terminate such contracts, foreclose upon collateral, exercise other default rights or restrict transfers of credit support in the event that the prudentially regulated entity and/or its affiliates are subject to certain types of resolution or insolvency proceedings. Similar regulations and laws have been adopted in non-U.S. jurisdictions that may apply to the Trust’s counterparties located in those jurisdictions. In particular, in the United Kingdom and the European Union, governmental authorities could reduce, eliminate or convert to equity the liabilities to a fund of a counterparty experiencing financial difficulties (sometimes referred to as a “bail in”). It is possible that these requirements, as well as potential additional related government regulation, could adversely affect the Trust’s ability to terminate existing derivatives contracts, exercise default rights or satisfy obligations owed to it with collateral received under such contracts.

Risks Associated with Artificial Intelligence and Machine Learning Technology

Recent technological advances in artificial intelligence and machine learning technology pose risks to the Trust and its portfolio investments. These advancements could harm the Trust and its portfolio investments by reducing the demand for both the technology and software offerings of the Trust’s portfolio investments. Additionally, these advancements could significantly disrupt the Trust’s portfolio investments and subject them to increased competition, which could have a material adverse effect on the Trust’s business, financial condition and results of operations. Also, artificial intelligence and machine learning technology advancements, including efficiency improvements, without related increases in the adoption and development of such technologies, could also negatively impact demand for, and the valuation of, digital infrastructure assets.

The Trust and its portfolio investments could be exposed to the risks of artificial intelligence and machine learning technology if third-party service providers or any counterparties, whether or not known to the Trust, also use artificial intelligence and machine learning technology in their business activities. The Trust and its portfolio companies may not be in a position to control the use of artificial intelligence and machine learning technology in third-party products or services.

Use of artificial intelligence and machine learning technology could include the input of confidential information in contravention of applicable policies, contractual or other obligations or restrictions, resulting in such confidential information becoming part accessible by other third-party artificial intelligence and machine learning technology applications and users.

Independent of its context of use, artificial intelligence and machine learning technology is generally highly reliant on the collection and analysis of large amounts of data, and it is not possible or practicable to incorporate all relevant data into the model that artificial intelligence and machine learning technology utilizes to operate. Certain data in such models will inevitably contain a degree of inaccuracy and error—potentially materially so—and could otherwise be inadequate or flawed, which would be likely to degrade the effectiveness of artificial intelligence and machine learning technology. To the extent that the Trust or its portfolio investments are exposed to the risks of artificial intelligence and machine learning technology use, any such inaccuracies or errors could have adverse impacts on the Trust or its investments.

October 2023, an executive order established new standards for AI safety and security. In addition to the U.S. regulatory framework, in 2024, the EU adopted the Artificial Intelligence Act in 2024, which applies to certain artificial intelligence and machine learning technology and the data used to train, test and deploy them, which may create additional compliance burdens, higher administrative costs and significant penalties should the Trust, the Advisor and its portfolio companies fail to comply.

Artificial intelligence and machine learning technology and its applications, including in the private investment and financial sectors, continue to develop rapidly, and it is impossible to predict the future risks that may arise from such developments. The full extent of current or future risks related thereto is not possible to predict and the Trust may not be able to anticipate, prevent, mitigate or remediate all of the potential risks, challenges or impacts of such changes.

MANAGEMENT OF THE TRUST

Investment Management Agreement

Although the Advisor intends to devote such time and effort to the business of the Trust as is reasonably necessary to perform its duties to the Trust, 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 Trust (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 Trust in connection with the performance of the Investment Management Agreement. The Investment Management Agreement also provides for indemnification by the Trust 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 Trust, subject to certain limitations and conditions.

The Investment Management Agreement provides for the Trust to pay a monthly management fee at an annual rate equal to 0.55% of the average daily value of the Trust’s Managed Assets. “Managed Assets” means the total assets of the Trust (including any assets attributable to money borrowed for investment purposes) minus the sum of the Trust’s accrued liabilities (other than money borrowed for investment purposes).

S-24

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 Trust (as such term is defined in the Investment Company Act) and (2) by the vote of a majority of the Trustees 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 Trust, without the payment of any penalty, upon the vote of a majority of the Trustees or a majority of the outstanding voting securities of the Trust 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 Trust to the Advisor, and the amounts waived by the Advisor, for the periods indicated:

Each Independent Trustee holds office until his or her successor is elected and qualifies, or until his or her earlier death, resignation, retirement or removal, or until December 31 of the year in which he or she turns 75. Board Members who are “interested persons,” as defined in the Investment Company Act, serve until their successor is elected and qualifies or until their earlier death, resignation, retirement or removal as provided by the Trust’s bylaws or statute, or until December 31 of the year in which they turn 72. The Board may determine to extend the terms of Independent Trustees on a case-by-case basis, as appropriate.

(3)

Date shown is the earliest date a person has served for the Trust. Following the combination of Merrill Lynch Investment Managers, L.P. (“MLIM”) and BlackRock, Inc. in September 2006, the various legacy MLIM and legacy BlackRock fund boards were realigned and consolidated into three new fund boards in 2007. Certain Independent Trustees first became members of the boards of other legacy MLIM or legacy BlackRock funds as follows: R. Glenn Hubbard, 2004 and W. Carl Kester, 1995. Certain other Independent Trustees became members of the boards of the closed-end funds in the BlackRock Fixed-Income Complex as follows: Cynthia L. Egan, 2016.

Experience, Qualifications and Skills of the Trustees

The Independent Trustees have adopted a statement of policy that describes the experiences, qualifications, skills and attributes that are necessary and desirable for potential Independent Trustee candidates (the “Statement of Policy”). The Board believes that each Independent Trustee satisfied, at the time he or she was initially elected or appointed a Board Member, and continues to satisfy, the standards contemplated by the Statement of Policy as well as the standards set forth in the Trust’s Bylaws. Furthermore, in determining that a particular Board Member was and continues to be qualified to serve as a Board Member, the Board has considered a variety of criteria, none of which, in isolation, was controlling. The Board believes that, collectively, the Board Members have balanced and diverse experiences, skills, attributes and qualifications, which allow the Board to operate effectively in governing the Trust and protecting the interests of shareholders. Among the attributes common to all Board Members 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 Board Members. Each Board Member’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 Trust 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.

Board Leadership Structure and Oversight

The Board has overall responsibility for the oversight of the Trust. The Chair of the Board and the Chief Executive Officer are different people. Not only is the Chair of the Board an Independent Trustee, but also the Chair of each Board committee (each, a “Committee”) is an Independent Trustee. The Board has seven standing Committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee, a Performance Oversight Committee, a Securities Lending Committee, a Discount Committee and an Executive Committee. The Trust does not have a compensation committee because its executive officers, other than the Trust’s Chief Compliance Officer (“CCO”), do not receive any direct compensation from the Trust, and the CCO’s compensation is comprehensively reviewed by the Board.

The role of the 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 Trustees between meetings. The Chair of each Committee performs a similar role with respect to such Committee. The Chair of the Board or the 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 Trustees meet regularly outside the presence of the Trust’s management, in executive sessions or with other service providers to the Trust. The Board has regular meetings five times a year, including a meeting to consider the approval of the Trust’s investment management agreement, and, if necessary, may hold special meetings before its next regular meeting. The Audit Committee, the Governance and Nominating Committee, the

S-31

Compliance Committee, the Performance Oversight Committee and the Securities Lending Committee each meets regularly and the Executive Committee and the Discount Committee each meets on an ad hoc basis 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 Chair because it believes that having an independent Chair:

•

increases the independent oversight of the Trust and enhances the Board’s objective evaluation of the Chief Executive Officer;

•

allows the Chief Executive Officer to focus on the Trust’s operations instead of Board administration;

•

provides greater opportunities for direct and independent communication between shareholders and the Board; and

•

provides an independent spokesman for the Trust.

The Board has engaged the Advisor to manage the Trust on a day-to-day basis. The Board is responsible for overseeing the Advisor, other service providers, the operations of the Trust and associated risks in accordance with the provisions of the Investment Company Act, state law, other applicable laws, the Trust’s agreement and declaration of trust, and the Trust’s investment objectives and strategies. The Board reviews, on an ongoing basis, the Trust’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 Trust.

Day-to-day risk management with respect to the Trust 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 Trust 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 Trust. Risk oversight is part of the Board’s general oversight of the Trust 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 Trust, the Advisor, and internal auditors for the Advisor or its affiliates, as appropriate, regarding risks faced by the Trust and management’s or the service provider’s risk functions. The Committee system facilitates the timely and efficient consideration of matters by the Trustees and facilitates effective oversight of compliance with legal and regulatory requirements and of the Trust’s activities and associated risks. The Board has approved the appointment of a CCO, who oversees the implementation and testing of the Trust’s compliance program and reports regularly to the Board regarding compliance matters for the Trust and its service providers. The Independent Trustees have engaged independent legal counsel to assist them in performing their oversight responsibilities.

Audit Committee. The Board has a standing Audit Committee composed of Lorenzo A. Flores (Chair), J. Phillip Holloman and Arthur P. Steinmetz, all of whom are Independent Trustees. 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 Trust. 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 Trust’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 Trust; (iii) reviewing the conduct and results of each audit; (iv) reviewing any issues raised by the Trust’s Independent Registered Public

S-32

Accounting Firm or management regarding the accounting or financial reporting policies and practices of the Trust, 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 Trust’s audited and unaudited financial statements and disclosure in the Trust’s shareholder reports relating to the Trust’s performance; (vi) assisting the Board’s responsibilities with respect to the internal controls of the Trust and its service providers with respect to accounting and financial matters; and (vii) resolving any disagreements between the Trust’s management and the Trust’s Independent Registered Public Accounting Firm regarding financial reporting. The Board has adopted a written charter for the Board’s Audit Committee. During the fiscal year ended December 31, 2025, the Audit Committee met seven times.

Governance and Nominating Committee. The Board has a standing Governance and Nominating Committee composed of W. Carl Kester (Chair), Cynthia L. Egan, J. Phillip Holloman and R. Glenn Hubbard, all of whom are Independent Trustees. The principal responsibilities of the Governance and Nominating Committee are: (i) identifying individuals qualified to serve as Independent Trustees and recommending Board nominees that are not “interested persons” of the Trust (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 with respect to Independent Trustee 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 Trustees; and (vii) reviewing and making recommendations to the Board in respect of Trust share ownership by the Independent Trustees. The Board has adopted a written charter for the Board’s Governance and Nominating Committee. During the fiscal year ended December 31, 2025, the Governance and Nominating Committee met five 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 Trust’s activities. In so doing, the Governance and Nominating Committee reviews the size of the Board, the ages of the current Trustees and their tenure on the Board, and the skills, background and experiences of the Trustees in light of the issues facing the Trust 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 Trustees as a group possess the array of skills, experiences and backgrounds necessary to guide the Trust. The Trustees’ biographies included herein highlight the diversity and breadth of skills, qualifications and expertise that the Trustees bring to the Trust.

The Governance and Nominating Committee may consider nominations for Trustees made by the Trust’s shareholders as it deems appropriate. Under the Trust’s Bylaws, shareholders must follow certain procedures to nominate a person for election as a Trustee 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 Trust at its principal executive offices no earlier than the 150^th day prior to the anniversary date of the immediately preceding annual meeting and not later than 5:00 p.m., Eastern Time, on the later of the 120^th day prior to such meeting or the tenth day following the day on which public notice of the date of the special meeting was mailed or public disclosure of the date of the meeting was made, whichever first occurs.

The Trust’s Bylaws provide that notice of a proposed nomination must include certain information about the shareholder and the nominee, as well as certain other information, including 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 Trust has adopted trustee qualification requirements

S-33

which can be found in the Trust’s By-laws and are applicable to all trustees that may be nominated, elected, appointed, qualified or seated to serve as Trustees. The qualification requirements may 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 Trust as defined under Section 2(a)(19) of the Investment Company Act, each Independent Trustee may not be or have certain relationships with a shareholder owning five percent or more of the Trust’s voting securities or owning other percentage ownership interests in investment companies registered under the Investment Company Act.

Compensation of Trustees

Each Independent Trustee is paid an annual retainer of $370,000 per year for his or her services as a Board member of the BlackRock-advised Funds, including the Trust, 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, the Chair of the Board and the Vice Chair of the Board are paid an additional annual retainer of

S-35

$140,000 and $84,000, respectively. The Chairs of the Audit Committee, Performance Oversight Committee, Compliance Committee, Governance and Nominating Committee, Discount Committee and Securities Lending Committee are each paid an additional annual retainer of $55,000, $42,500, $50,000, $42,500, $25,000 and $20,000, respectively. Each of the other members of the Audit Committee, Compliance Committee, Governance and Nominating Committee, Discount Committee and Securities Lending Committee is paid an additional annual retainer of $30,000, $25,000, $25,000, $20,000 and $15,000, respectively, for his or her service on such committee. An Independent Trustee may receive additional compensation for his or her service as a member or Chair, as applicable, of one or more ad hoc committees of the Board. The Trust will pay a pro rata portion quarterly (based on relative net assets) of the foregoing Trustee fees paid by the funds in the BlackRock Fixed-Income Complex.

The Independent Trustees have agreed that a maximum of 50% of each Independent Trustee’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 Trustees as though equivalent dollar amounts had been invested in shares of certain funds in the BlackRock Fixed-Income Complex selected by the Independent Trustees. This has approximately the same economic effect for the Independent Trustees 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.

The following table sets forth the compensation paid to the Trustees by the Trust for the fiscal year ended December 31, 2025, and the aggregate compensation, including deferred compensation amounts, paid to them by all BlackRock-advised Funds for the calendar year ended December 31, 2025. Messrs. Fairbairn and Perlowski serve without compensation from the Trust because of their affiliation with BlackRock, Inc. and the Advisor.

Independent Trustee Ownership of Securities

As of December 31, 2025, none of the Independent Trustees of the Trust 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 Trustees of the Trust or their immediate family members have any material interest in any transaction, or series of similar transactions, during the most recently completed two calendar years involving the Trust, BlackRock or any affiliate of any BlackRock person controlling, controlled by or under common control with the Trust or BlackRock.

As of the date of this SAI, the officers and Trustees of the Trust, as a group, directly or indirectly beneficially owned an aggregate of less than 1% of the outstanding common shares of the Trust.

Information Pertaining to the Officers

Please refer to the section of the Trust’s May 22, 2025 definitive proxy statement on Schedule 14A for the annual meeting of the Trust’s shareholders entitled: “Appendix F – Information Pertaining to the Executive Officers of the Funds,” which is incorporated by reference herein, for certain biographical and other information relating to the officers of the Trust who are not Trustees.

Indemnification of Trustees and Officers

The governing documents of the Trust generally provide that, to the extent permitted by applicable law, the Trust will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust unless, as to liability to the Trust 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 Trust will not indemnify Trustees with respect to any matter as to which Trustees did not act in good faith in the reasonable belief that his or her action was in the best interest of the Trust or, in the case of any criminal proceeding, as to which Trustees had reasonable cause to believe that the conduct was unlawful. Indemnification provisions contained in the Trust’s governing documents are subject to any limitations imposed by applicable law.

Closed-end funds in the BlackRock Fixed-Income Complex, including the Trust, 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.

Portfolio Manager Compensation Overview

The discussion below describes the portfolio managers’ compensation as of December 31, 2025.

BlackRock’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 BlackRock.

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

Discretionary Incentive Compensation. 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 Trust 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 Trust 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 Trust and other accounts are: a combination of market-based indices (e.g., Bloomberg 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.

S-38

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 the Trust 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 ($350,000 for 2025). 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.

Portfolio Manager Potential Material Conflicts of Interest

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.

S-39

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 Trust, 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 Trust. 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 Trust. 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 Trust 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 hedge fund and/or long only accounts, or may be part of a team managing 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 the Trust 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.

Proxy Voting Policies

The Board of the Trust has delegated the voting of proxies for the Trust’s securities to the Advisor pursuant to the Closed-End Fund Proxy Voting Policy. The Advisor has adopted the BlackRock Active Investment Stewardship - Global Engagement and Voting Guidelines (the “BAIS Guidelines”) with respect to certain funds, including the Trust.

Copies of the Closed-End Fund Proxy Voting Policy and the BAIS Guidelines are attached as Appendix B to this SAI.

Information on how the Trust voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available (i) without charge, upon request, by calling (800) 882-0052, (ii) at www.blackrock.com and (iii) on the SEC’s website at http://www.sec.gov.

Codes of Ethics

The Trust 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 Trust. 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.

S-40

Other Information

BlackRock, Inc. is independent in ownership and governance, with no single majority stockholder and a majority of independent directors.

PORTFOLIO TRANSACTIONS AND BROKERAGE

Subject to policies established by the Board, the Advisor is primarily responsible for the execution of the Trust’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 Trust, taking into account certain factors set out below. While the Advisor generally seeks reasonable trade execution costs, the Trust 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 Trust. In return for such services, the Advisor may cause the Trust 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 Trust, 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 Securities Exchange Act of 1934, as amended (the “Exchange Act,” and Section 28(e) thereof, “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 Trust.

The Advisor, unless prohibited by applicable law, 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 Trust may be subject to additional regulations, including MiFID II. Under MiFID II, European Union (“EU”) investment managers pay for any research out of their own resources and not through soft dollars or commission

S-41

sharing arrangements. 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, unless prohibited by applicable law, 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 Trust 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 Trust 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 Trust 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.

Under MiFID II, investment managers in the EU are not able to use soft dollars to pay for research from brokers. Investment managers in the EU are required to either pay for research out of their own profit and loss or agree with clients to have research costs paid by clients through research payment accounts that are directly funded or funded by a specific client research charge collected alongside execution commissions, provided that the payments for research are unbundled from the payments for execution.

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

From time to time, the Trust 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 Trust; however, whether or not a particular broker

S-42

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 Trust 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 Trust 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 Trust 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 Trust and persons who are affiliated with such affiliated persons are prohibited from dealing with the Trust 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 Trust will not deal with affiliated persons in connection with such transactions. However, an affiliated person of the Trust 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 Trust 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 Trust are made from dealers, underwriters and issuers. The Trust 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 offered securities are purchased or sold directly from or to an issuer, no commissions or discounts are paid except where required by local markets.

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 Trust prior to maturity at their original cost plus interest (sometimes adjusted to reflect the actual maturity of the securities), if it believes that the Trust’s anticipated need for liquidity makes such action desirable. Any such repurchase prior to maturity reduces the possibility that the Trust 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 Trust 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 over time. 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,

S-43

(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. 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. In these situations, 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 client 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 Trust 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 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 aggregated in a single order if the trader believes the aggregated trade would provide each client with an opportunity to achieve a more favorable execution at a potentially lower execution cost. The costs associated with an aggregated order will be shared pro rata among the clients in the aggregated 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 Trust is concerned, in other cases it could

S-44

be beneficial to the Trust. 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 aggregated 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 aggregated orders will be kept aggregated only long enough to execute the order.

The Trust’s purchase and sale orders for securities may be combined with those of other investment companies, clients or accounts that the Advisor manages or advises. If purchases or sales of portfolio securities of the Trust and one or more other accounts managed or advised by the Advisor are considered at or about the same time, transactions in such securities are allocated among the Trust and the other accounts in a manner deemed equitable to all by the Advisor. In some cases, this procedure could have a detrimental effect on the price or volume of the security as far as the Trust is concerned. However, in other cases, it is possible that the ability to participate in volume transactions and to negotiate lower transaction costs will be beneficial to the Trust. The Advisor may deal, trade and invest for its own account in the types of securities in which the Trust may invest. The Advisor may, from time to time, effect trades on behalf of and for the account of the Trust with brokers or dealers that are affiliated with BlackRock Fund Advisors, in conformity with the Investment Company Act and Commission rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions. The Trust will not deal with affiliates in principal transactions unless permitted by applicable Commission rules or regulations, or by Commission exemptive order.

The Trust 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 Trust 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 Trust’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 Trust.

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


Fiscal Year Ended December 31,	Aggregate Brokerage Commissions Paid	Commissions Paid to Affiliates
2025	$14,219	$ 0
2024	$15,869	$ 0
2023	$27,565	$ 0

For the fiscal year ended December 31, 2025, the brokerage commissions paid to affiliates by the Trust represented 0% of the aggregate brokerage commissions paid and involved 0% of the dollar amount of transactions involving payment of commissions during the year.

S-45

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 December 31, 2025. The provision of third-party research services was not necessarily a factor in the placement of all brokerage business with such brokers.


Amount of Commissions Paid to Brokers for Providing Research Services		Amount of Brokerage Transactions Involved

As of December 31, 2025, the Trust 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 December 31, 2025.

POTENTIAL CONFLICTS OF INTEREST

Certain activities of BlackRock, Inc., BlackRock Advisors, LLC, BlackRock Fund Advisors and the other subsidiaries of BlackRock, Inc. (collectively referred to in this section as “BlackRock”) and their respective directors, officers or employees, with respect to the Trust and/or other accounts managed by BlackRock, 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. BlackRock, its subsidiaries and their respective directors, officers and employees, including the business units or entities and personnel who may be involved in the investment activities and business operations of the Trust, are engaged worldwide in businesses, including managing equities, fixed income securities, cash and alternative investments, and other financial services, and have interests other than that of managing the Trust. These are considerations of which investors in the Trust should be aware, and which may cause conflicts of interest that could disadvantage the Trust 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 Trust.

BlackRock may 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 identical or similar to those of the Trust and/or that engage in transactions in the same types of securities, currencies and instruments as the Trust. Such other funds or accounts may offer exposure to strategies that are identical or substantially similar to those of the Trust but with different fees and expenses, governance and structures, and/or services provided by BlackRock. BlackRock is also a major participant 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 is or may be actively engaged in transactions in the same securities, currencies, and instruments in which the Trust invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which the Trust invests, which could have an adverse impact on the Trust’s performance. Such transactions, particularly in respect of most proprietary accounts or client accounts, will be executed independently of the Trust’s transactions and thus at prices or rates that may be more or less favorable than those obtained by the Trust.

In addition, the portfolio holdings of certain BlackRock-advised investment vehicles managed in an identical or substantially similar manner as certain funds are made publicly available on a more timely basis than the applicable fund. In some cases, such portfolio holdings are made publicly available on a daily basis. While not expected, it is possible that a recipient of portfolio holdings information for such an investment vehicle could cause harm to the fund that is managed in an identical or substantially similar manner, including by trading ahead of or against such fund based on the information received.

When BlackRock seeks to purchase or sell the same assets for client accounts, including the Trust, the assets actually purchased or sold may be allocated among the accounts on a basis determined in its good faith discretion

S-46

to be equitable. In some cases, this system may adversely affect the size or price of the assets purchased or sold for the Trust. In addition, transactions in investments by one or more other accounts managed by BlackRock may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Trust, 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 Trust 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 Trust, market impact, liquidity constraints, or other factors could result in the Trust receiving less favorable trading results and the costs of implementing such decisions or strategies could be increased or the Trust 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 Trust 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 Trust may benefit other accounts managed by BlackRock. For example, the sale of a long position or establishment of a short position by the Trust 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 Trust may increase the price of the same security held by (and therefore benefit) BlackRock or its other accounts or funds.

BlackRock, on behalf of other client accounts, on the one hand, and the Trust, on the other hand, may invest in or extend credit to different parts of the capital structure of a single issuer. BlackRock may pursue rights, provide advice or engage in other activities, or refrain from pursuing rights, providing advice or engaging in other activities, on behalf of other clients with respect to an issuer in which the Trust has invested, and such actions (or refraining from action) may have a material adverse effect on the Trust. In situations in which clients of BlackRock (including the Trust) hold positions in multiple parts of the capital structure of an issuer, BlackRock may not pursue certain actions or remedies that may be available to the Trust, as a result of legal and regulatory requirements or otherwise. BlackRock addresses these and other potential conflicts of interest based on the facts and circumstances of particular situations. For example, BlackRock may determine to rely on information barriers between different business units or portfolio management teams. BlackRock may also determine to rely on the actions of similarly situated holders of loans or securities rather than, or in connection with, taking such actions itself on behalf of the Trust.

In addition, to the extent permitted by applicable law, the Trust 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 Trust purchases and redemptions, and increased remuneration and profitability for BlackRock and/or its personnel, including portfolio managers.

Third parties, including service providers to BlackRock or the Trust, may sponsor events (including, but not limited to, marketing and promotional activities and presentations, educational training programs and conferences) for registered representatives, other professionals and individual investors. There is a potential conflict of interest as such sponsorships may defray the costs of such activities to BlackRock, and may provide an incentive to BlackRock to retain such third parties to provide services to the Trust.

In certain circumstances, BlackRock, on behalf of the Trust, 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 Trust, 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 Trust. BlackRock may have a potentially conflicting division of loyalties and responsibilities to the parties in such transactions.

BlackRock and its clients may pursue or enforce rights with respect to an issuer in which the Trust has invested, and those activities may have an adverse effect on the Trust. As a result, prices, availability, liquidity and terms

S-47

of the Trust’s investments may be negatively impacted by the activities of BlackRock or its clients, and transactions for the Trust 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 Trust’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) that 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 Trust. Moreover, it is possible that the Trust 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 Trust 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 other accounts managed or advised by BlackRock, and/or the internal policies of BlackRock 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 is 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 Trust 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 Trust, 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 Trust in accordance with such analysis and models. In addition, BlackRock will not have any obligation to make available any information regarding its proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for the benefit of the management of the Trust and it is not anticipated that BlackRock will have access to such information for the purpose of managing the Trust. 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 Trust.

The Trust may be included in investment models developed by BlackRock for use by clients and financial advisors. To the extent clients invest in these investment models and increase the assets under management of the Trust, the investment management fee amounts paid by the Trust to BlackRock may also increase. The net asset value and liquidity of the Trust may be impacted by purchases and sales of the Trust by model-driven investment portfolios, as well as by BlackRock itself and by its advisory clients.

In addition, certain principals and certain employees of the Trust’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 Trust should be aware.

BlackRock may enter into transactions and invest in securities, instruments and currencies on behalf of the Trust in which clients of BlackRock, or, to the extent permitted by the SEC and applicable law, BlackRock, 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 Trust, and such party may have no incentive to assure that the Trust obtains the best possible prices or terms in connection with the transactions. In addition, the purchase, holding and sale of such investments by the Trust may enhance the profitability of BlackRock.

BlackRock may also create, write or issue derivatives for clients, the underlying securities, currencies or instruments of which may be those in which the Trust invests or which may be based on the performance of the

S-48

Trust. Additionally, an affiliate of BlackRock will create, write or issue options, which may be based on the performance of certain BlackRock-advised funds. 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. Trading activity in these derivative products could also potentially lead to greater liquidity for such products, increased purchase activity with respect to these iShares ETFs and increased assets under management for BlackRock.

The Trust may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by BlackRock and may also enter into transactions with other clients of BlackRock where such other clients have interests adverse to those of the Trust. At times, these activities may cause business units or entities within BlackRock to give advice to clients that may cause these clients to take actions adverse to the interests of the Trust. To the extent such transactions are permitted, the Trust will deal with BlackRock on an arms-length basis.

To the extent authorized by applicable law, BlackRock may act as broker, dealer, agent, lender or adviser or in other commercial capacities for the Trust. 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 will be in its view commercially reasonable, although BlackRock, including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to BlackRock and such sales personnel, which may have an adverse effect on the Trust. Index based funds may use an index provider that is affiliated with another service provider of the Trust or BlackRock that acts as a broker, dealer, agent, lender or in other commercial capacities for the Trust or BlackRock.

Subject to applicable law, BlackRock (and its personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Trust as broker, dealer, agent, lender, adviser or in other commercial capacities. No accounting to the Trust or its shareholders will be required, and no fees or other compensation payable by the Trust or its shareholders will be reduced by reason of receipt by BlackRock of any such fees or other amounts.

When BlackRock acts as broker, dealer, agent, adviser or in other commercial capacities in relation to the Trust, BlackRock may take commercial steps in its own interests, which may have an adverse effect on the Trust.

The Trust will be required to establish business relationships with its counterparties based on the Trust’s own credit standing. BlackRock will not have any obligation to allow its credit to be used in connection with the Trust’s establishment of its business relationships, nor is it expected that the Trust’s counterparties will rely on the credit of BlackRock in evaluating the Trust’s creditworthiness.

BlackRock Investment Management, LLC (“BIM”) or BlackRock Institutional Trust Company, N.A. (“BTC”), as applicable, each 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 Trust. BlackRock will also 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) BlackRock as securities lending agent may have an incentive to, among other things, increase or decrease the amount of securities on loan or to lend particular securities in order to generate additional risk-adjusted revenue for BlackRock and its affiliates; and (ii) BlackRock as securities lending agent may have an incentive to allocate loans to clients that would provide more revenue to BlackRock . As described further below, BlackRock 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 the Trust and certain other clients and/or funds against a shortfall in collateral in the event of borrower default. On a regular basis, BlackRock calculates the

S-49

potential dollar exposure of collateral shortfall resulting from a borrower default (“shortfall risk”) in the securities lending program. BlackRock establishes program-wide borrower limits (“credit limits”) to actively manage borrower-specific credit exposure. BlackRock oversees the risk model that calculates projected collateral shortfall values using loan-level factors such as loan and collateral type and market value as well as specific borrower credit characteristics. When necessary, BlackRock may adjust securities lending program attributes by restricting eligible collateral or reducing borrower credit limits. As a result, the management of program-wide exposure as well as BlackRock-specific indemnification exposure may affect the amount of securities lending activity BlackRock may conduct at any given point in time by reducing the volume of lending opportunities for certain loans (including by asset type, collateral type and/or revenue profile).

BlackRock may decline to make a securities loan on behalf of the Trust, discontinue lending on behalf of the Trust or terminate a securities loan on behalf of the Trust for any reason, including but not limited to regulatory requirements and/or market rules, liquidity considerations, or credit considerations, which may impact the Trust by reducing or eliminating the volume of lending opportunities for certain types of loans, loans in particular markets, loans of particular securities or types of securities, or for loans overall. In addition, some borrowers may prefer certain BlackRock lenders that provide additional protections against lender default that are favored by their prudential regulation.

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 borrower 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 Trust may be 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 aggregate orders if portfolio management decisions for different accounts are made separately, or if they determine that 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 Trust 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 Trust. In addition, under certain circumstances, the Trust will not be charged the same commission or commission equivalent rates in connection with an aggregated order.

As discussed in the section above entitled “Portfolio Transactions and Brokerage,” BlackRock, unless prohibited by applicable law, may cause the Trust 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. Under MiFID II, EU investment managers pay for research from brokers and dealers directly out of their own resources, rather than through client commissions.

Subject to applicable law, BlackRock may select brokers that furnish BlackRock, the Trust, 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

S-50

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 Trust 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 Trust based on the amount of brokerage commissions paid by the Trust 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 Trust 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 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 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 Trust. 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 owns a minority interest in, and is a member of, Members Exchange (“MEMX”), a newly created U.S. stock exchange. Transactions for the Trust may be executed on MEMX if third party brokers select MEMX as the appropriate venue for execution of orders placed by BlackRock traders on behalf of client portfolios.

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 Trust, 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, 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 “Proxy Voting Policies.”

It is also possible that, from time to time, BlackRock and/or its advisory clients (including other funds and separately managed accounts) may, subject to compliance with applicable law, purchase and hold shares of the Trust. Increasing the Trust’s assets may enhance investment flexibility and diversification and may contribute to economies of scale that tend to reduce the Trust’s expense ratio. BlackRock reserves the right, subject to compliance with applicable law, to redeem at any time some or all of the shares of the Trust acquired for its own

S-51

accounts. A large redemption of shares of the Trust by BlackRock could significantly reduce the asset size of the Trust, which might have an adverse effect on the Trust’s investment flexibility, portfolio diversification and expense ratio. BlackRock seeks to consider the effect of redemptions on the Trust and other shareholders in deciding whether to redeem its shares but is not obligated to do so and may elect not to do so.

It is possible that the Trust may invest in securities of, or engage in transactions with, companies in which BlackRock has significant debt or equity investments or other interests. The Trust 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. In making investment decisions for the Trust, 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 may limit the Trust’s flexibility in purchases and sales of securities. As indicated below, BlackRock may engage in transactions with companies in which BlackRock-advised funds or other clients of BlackRock have an investment.

BlackRock and its personnel and other financial service providers may have interests in promoting sales of the Trust. With respect to BlackRock and its personnel, the remuneration and profitability relating to services to and sales of the Trust or other products may be greater than remuneration and profitability relating to services to and sales of certain funds or other products that might be provided or offered. BlackRock and its sales personnel may directly or indirectly receive a portion of the fees and commissions charged to the Trust or its shareholders. BlackRock and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions may also be higher than for other products or services, and the remuneration and profitability to BlackRock and such personnel resulting from transactions on behalf of or management of the Trust may be greater than the remuneration and profitability resulting from other funds or products.

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 Trust’s pricing vendors, especially if such valuations are based on broker-dealer quotes or other data sources unavailable to the Trust’s pricing vendors. While BlackRock will generally communicate its valuation information or determinations to the Trust’s pricing vendors and/or fund accountants, there may be instances where the Trust’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 Trust’s investments are valued at fair value by BlackRock. BlackRock has been designated as the Trust’s valuation designee pursuant to Rule 2a-5 under the Investment Company Act and acts through BlackRock’s Rule 2a-5 Committee (the “2a-5 Committee”), with assistance from other BlackRock pricing committees and in accordance with BlackRock’s policies and procedures (the “Valuation Procedures”). When determining a “fair value price,” the 2a-5 Committee seeks to determine the price that the Trust 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 Trust 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 Trust’s NAV. As a result, the Trust’s sale or repurchase of its shares at NAV, at a time when a holding or holdings are valued by the 2a-5 Committee 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.

S-52

To the extent permitted by applicable law, the Trust 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 Trust, 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 Trust 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 Trust. 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 Trust. To lessen the possibility that the Trust will be adversely affected by this personal trading, the Trust 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 Trust’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 Trust, except that the Trust may in accordance with rules or guidance adopted under the Investment Company Act engage in transactions with another fund or accounts that are affiliated with the Trust as a result of common officers, directors, or investment advisers or pursuant to exemptive orders granted to the Trust and/or BlackRock by the Commission. These transactions would be effected in circumstances in which BlackRock determined that it would be appropriate for the Trust to purchase and another client of BlackRock to sell, or the Trust 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 Trust 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 that 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 its advice regarding certain securities or instruments issued by or related to companies for which BlackRock is performing 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 Trust, 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). Moreover, applicable provisions of the Investment Company Act or other regulatory considerations may restrict the Trust or BlackRock from effecting certain portfolio transactions or taking other actions in respect of an investment on behalf of the Trust, including where BlackRock and/or clients advised by BlackRock already have an interest in such issuer or the investment. Similar situations could arise if personnel of BlackRock serve as directors of companies the securities of which the Trust 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 Trust may purchase securities or instruments that are issued by such companies, are the subject of an advisory or risk management assignment by BlackRock, or where personnel of BlackRock are directors or officers of the issuer.

BlackRock has adopted and implemented policies and procedures that are designed to address potential conflicts that arise in connection with the advisory services BlackRock provides to the Trust and other clients. Certain BlackRock advisory personnel may take views, and make decisions or recommendations, that are different than or opposite those of other BlackRock advisory personnel. Certain portfolio management teams within BlackRock may make decisions or take (or refrain from taking) actions with respect to clients they advise in a manner different than or adverse to the decisions made or the actions taken (or not taken) by the Trust’s portfolio management teams. The various portfolio management teams may not share information with each other, including as a result of certain information barriers and other policies, and will not have any obligation or other duty to do so.

S-53

BlackRock has established certain information barriers and other policies to address the sharing of information between different businesses within BlackRock, including with respect to personnel responsible with managing portfolios and voting proxies with respect to certain index equity portfolios versus those responsible for managing portfolios and voting proxies with respect to all other portfolios. As a result of information barriers, certain units of BlackRock generally will not have access, or will have limited access, to certain information and personnel, including senior personnel, in other units of BlackRock, and generally will not manage the Trust with the benefit of information possessed by such other units. Therefore, BlackRock may not be able to review potential investments for the Trust with the benefit of information held by certain areas of BlackRock.

BlackRock may determine to move certain personnel, businesses, or business units from one side of an information barrier to the other side of the information barrier. In connection therewith, BlackRock personnel, businesses, and business units that were moved will no longer have access to the information and personnel from the side of the information barrier from which they were moved. Information obtained in connection with such changes to information barriers may limit or restrict the ability of BlackRock to engage in or otherwise effect transactions on behalf of the Trust (including purchasing or selling securities that BlackRock may otherwise have purchased or sold for a client in the absence of a change to an information barrier). Information barriers may not have their intended impact due to, for example, changes in applicable law or inadvertent crossings of the barriers, and actions by personnel on one side of a barrier may impact the potential actions of personnel on the other side of a barrier.

Although the information barriers are intended to allow for independent portfolio management decision-making and proxy voting among certain BlackRock businesses, the investment activities of BlackRock for BlackRock clients, as well as BlackRock’s proprietary accounts, may nonetheless limit the investment strategies and rights of other clients (including the Trust). As BlackRock’s assets under management increases, BlackRock clients may face greater negative impacts due to ownership restrictions and limitations imposed by laws, regulations, rules, regulators, or issuers. For example, in certain circumstances where a BlackRock client invests in securities issued by companies that operate in certain industries (e.g., banking, insurance, and utilities) or in certain emerging or international markets, or are subject to regulatory or corporate ownership restrictions (e.g., with mechanisms such as poison pills in place to prevent takeovers), or where a BlackRock client invests in certain futures and derivatives, there may be limits on the aggregate amount invested by BlackRock for its clients and BlackRock’s proprietary accounts that may not be exceeded without the grant of a license or other regulatory or corporate approval, order, consent, relief, waiver or non-disapproval or, if exceeded, may cause BlackRock or its clients to be subject to enforcement actions, disgorgement of share ownership or profits, regulatory restrictions, complex compliance reporting, increased compliance costs or suffer disadvantages or business restrictions. In light of certain restrictions, BlackRock may also seek to make indirect investments (e.g., using derivatives) on behalf of its clients to receive exposure to certain securities in excess of the applicable ownership restrictions and limitations when legally permitted that will expose such clients to additional costs and additional risks, including any risks associated with investing in derivatives. There may be limited availability of derivatives that provide indirect exposure to an impacted security. BlackRock clients can be subject to more than one ownership limitation depending on each client’s holdings, and each ownership limitation can impact multiple securities held by the client. Certain clients or shareholders may have their own overlapping obligations to monitor their compliance with ownership limitations across their investments.

If certain aggregate ownership thresholds are reached either through the actions of BlackRock or a BlackRock client or as a result of corporate actions by the issuer, the ability of BlackRock on behalf of clients to purchase or dispose of investments, or exercise rights (including voting) or undertake business transactions, may be restricted by law, regulation, rule, or organizational documents or otherwise impaired. For example, to meet the requirements of an ownership limitation or restriction, a client may be unable to purchase or directly hold a security the client would otherwise purchase or hold. The limitation or restriction may be based on the holdings of other BlackRock clients instead of the specific client being restricted. For index funds, this means a fund may not be able to track its index as closely as it would if it was not subject to an ownership limitation or restriction because the fund cannot acquire the amount of the impacted security included in its index. BlackRock on behalf

S-54

of its clients may limit purchases, sell existing investments, utilize information barriers, 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. These types of restrictions could negatively impact a client’s performance or ability to meet its investment objective.

When BlackRock or a BlackRock client is subject to an ownership limitation, BlackRock may in its discretion seek permission from the applicable issuers or regulators to exceed the limitation. However, there is no guarantee that permission will be granted, or that, once granted, it will not be modified or revoked at a later date with minimal or no notice. The issuer and/or regulator may also require that BlackRock on behalf of itself and its clients take or refrain from taking certain actions in connection with the approval, order, consent, relief or non-disapproval, which BlackRock may accept if it believes the benefits outweigh the costs and may limit BlackRock from taking actions that it otherwise would take. In those circumstances where ownership thresholds or limitations must be observed, BlackRock seeks to allocate limited investment opportunities equitably among clients, taking into consideration benchmark weight and investment strategy. BlackRock may adopt certain controls designed to prevent the occurrence of a breach of any applicable ownership thresholds or limits, including, for example, when ownership in certain securities nears an applicable threshold, BlackRock may limit additional purchases in such securities or, with respect to ETFs, remove such securities from the list of Deposit Securities to be delivered to the Trust in connection with purchases of Creation Units of such Fund. If client 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 reduce these positions to meet the applicable limitations and BlackRock or such client may be subject to regulatory actions. In these cases, the investments will be sold in a manner that BlackRock deems fair and equitable over time.

Ownership limitations are highly complex. It is possible that, despite BlackRock’s intent to either comply with or be granted permission to exceed ownership limitations, it may inadvertently breach a limit or violate the corporate or regulatory approval, order, consent, relief or non-disapproval that was obtained.

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 Trust 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 Trust’s 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. In instances where BlackRock charges a unitary management fee, BlackRock may have a financial incentive to use a BlackRock index that is less costly to BlackRock than a third party index. BlackRock may benefit from the Trust using BlackRock indices by creating increasing acceptance in the marketplace for such indices. BlackRock is not obligated to license its indices to the Trust and the Trust is under no obligation to use BlackRock indices. Any fund that enters into a license for a BlackRock index 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 Trust (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. BlackRock may also enter into contractual arrangements with such service providers pursuant to which BlackRock incurs additional costs if the service provider’s services are terminated with respect to the Trust. To the extent that BlackRock is responsible for paying service providers out of its fees that it receives from the Trust, the benefits of lower fees, including any fee discounts or concessions, or any additional savings, may accrue, in whole or in part, to

S-55

BlackRock, which could result in conflicts of interest relating to the use or termination of service providers to the Trust. In addition, conflicts of interest may arise with respect to contractual arrangements with third-party service providers to the Trust, or the selection of such providers, particularly in circumstances where BlackRock is negotiating on behalf of both funds that have a unitary management fee and those that do not or different service providers have different fee structures.

Conflicts of interest may arise as a result of simultaneous investment management of multiple client accounts by the BlackRock’s investment professionals. For example, differences in the advisory fee structure may create the appearance of actual or potential conflicts of interest because such differences could create pecuniary incentives for BlackRock to favor one client account over another.

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

In recognition of a BlackRock client’s overall relationship with BlackRock, BlackRock may offer special pricing arrangements for certain services provided by BlackRock. Any such special pricing arrangements will not affect Trust fees and expenses applicable to such client’s investment in the Trust.

Present and future activities of BlackRock and its directors, officers and employees, in addition to those described in this section, may give rise to additional conflicts of interest.

DESCRIPTION OF SHARES

Common Shares

The Trust 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.

Preferred Shares

The Trust currently does not intend to issue preferred shares. Although the terms of any preferred shares that the Trust 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 Agreement and Declaration of Trust, it is likely that any such preferred shares 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 Trust also believes that it is likely that the liquidation preference, voting rights and redemption provisions of any such preferred shares would be similar to those stated below.

Liquidation Preference. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Trust, the holders of preferred shares will be entitled to receive a preferential liquidating distribution, which would be expected to equal the original purchase price per preferred share plus accrued and unpaid dividends, whether or not declared, before any distribution of assets is made to holders of common shares. After payment of the full amount of the liquidating distribution to which they are entitled, the holders of preferred shares would not be entitled to any further participation in any distribution of assets by the Trust.

S-56

Voting Rights. The Investment Company Act requires that the holders of any preferred shares, voting separately as a single class, have the right to elect at least two Trustees at all times. The remaining Trustees will be elected by holders of common shares and preferred shares, voting together as a single class. In addition, subject to the prior rights, if any, of the holders of any other class of senior securities outstanding, the holders of any preferred shares have the right to elect a majority of the Trustees at any time two years’ dividends on any preferred shares are unpaid. The Investment Company Act also requires that, in addition to any approval by shareholders that might otherwise be required, the approval of the holders of a majority of any outstanding preferred shares, voting separately as a class, would be required to (1) adopt any plan of reorganization that would adversely affect the preferred shares, and (2) take any action requiring a vote of security holders under Section 13(a) of the Investment Company Act, including, among other things, changes in the Trust’s sub-classification as a closed-end investment company or changes in its fundamental investment restrictions. See “Certain Provisions in the Agreement and Declaration of Trust and Bylaws” in the Prospectus. As a result of these voting rights, the Trust’s ability to take any such actions may be impeded to the extent that there are any preferred shares outstanding. The Board presently intends that, except as otherwise indicated in the Prospectus or this SAI and except as otherwise required by applicable law, holders of any preferred shares will have equal voting rights with holders of common shares (one vote per share, unless otherwise required by the Investment Company Act) and will vote together with holders of common shares as a single class.

The affirmative vote of the holders of a majority of any outstanding preferred shares, voting as a separate class, would be required to amend, alter or repeal any of the preferences, rights or powers of holders of preferred shares so as to affect materially and adversely such preferences, rights or powers, or to increase or decrease the authorized number of preferred shares. The class vote of holders of preferred shares described above would in each case be in addition to any other vote required to authorize the action in question.

Redemption Provisions. It is anticipated that any outstanding shares of preferred shares will generally be redeemable at the option of the Trust 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 shares 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 Trust to maintain asset coverage requirements for the preferred shares specified by the Investment Company Act and rating services that issue ratings on the preferred shares.

Liquidity Feature. Preferred shares may 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 Trust will pay a fee to the provider of this liquidity feature, which would be borne by common shareholders of the Trust. The terms of such liquidity feature may require the Trust to redeem preferred shares still owned by the liquidity provider following a certain period of continuous, unsuccessful remarketing, which may adversely impact the Trust.

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

Other Shares

The Board (subject to applicable law and the Agreement and Declaration of Trust) may authorize an offering, without the approval of the holders of common shares and, depending on their terms, any preferred shares 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 Trust currently does not expect to issue any other classes of shares, or series of shares, except for the common shares.

S-57

REPURCHASE OF COMMON SHARES

The Trust is a closed-end management investment company and as such its shareholders will not have the right to cause the Trust to redeem their shares. Instead, the Trust’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, market sentiment 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 Trust 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 Trust has preferred shares outstanding, the Trust 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 Trust’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 Trust will be borne by the Trust and will not reduce the stated consideration to be paid to tendering shareholders.

Subject to its investment restrictions, the Trust 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 Trust in anticipation of share repurchases or tender offers will reduce the Trust’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 Trust’s status as a RIC under the Code, (which would make the Trust a taxable entity, causing the Trust’s income to be taxed at the corporate level in addition to the taxation of shareholders who receive dividends from the Trust) or as a registered closed-end investment company under the Investment Company Act; (ii) the Trust would not be able to liquidate portfolio securities in an orderly manner and consistent with the Trust’s investment objectives 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 Trust, (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 Trust 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 Trust or its shareholders if shares were repurchased. The Board may in the future modify these conditions in light of experience.

The repurchase by the Trust 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 Trust’s common shares trading at a price equal to their NAV. Nevertheless, the fact that the Trust’s common shares may be the subject of repurchases or tender offers from time to time, or that the

S-58

Trust 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 Trust of its common shares will decrease the Trust’s net assets which would likely have the effect of increasing the Trust’s expense ratio. Any purchase by the Trust 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 Trust’s portfolio, the impact of any action that might be taken on the Trust or its shareholders and market considerations. Based on these considerations, even if the Trust’s common shares should trade at a discount, the Board may determine that, in the interest of the Trust and its shareholders, no action should be taken.

TAX MATTERS

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 Trust. 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 (the “IRS”), possibly with retroactive effect. No attempt is made to present a detailed explanation of all U.S. federal income tax concerns affecting the Trust and its shareholders, and the discussions set forth here do not constitute tax advice. This discussion assumes that investors hold common shares of the Trust as capital assets for U.S. federal income tax purposes(generally, assets held for investment). The Trust has not sought and will not seek any ruling from the IRS regarding any matters discussed herein. No assurance can be given that the IRS 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 non-U.S., 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 Trust’s common shares, as well as the effects of state, local and non-U.S. tax laws.

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 Trust 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:

•

a citizen or individual resident of the United States (including certain former citizens and former long-term residents);

•

an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

•

S-59

decisions or the trust has made a valid election in effect under applicable Treasury regulations to be treated as a U.S. person.

Taxation of the Trust

The Trust 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 Trust 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 Trust 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 Trust 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 Trust’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 market value of the Trust’s 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 Trust and engaged in the same, similar or related trades or businesses, or any one or more “qualified publicly traded partnerships.”

As long as the Trust qualifies as a RIC, the Trust 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 Trust 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 Trust 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 Trust to the extent the Trust 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 Trust’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 the total amount of any under-distribution or over-distribution, as the case may be, from the previous year. For purposes of the excise tax, the Trust will be deemed to have distributed any income on which it paid U.S. federal income tax. While the Trust 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 Trust’s taxable income and capital gain will be distributed to entirely avoid the imposition of the excise tax. In that event, the Trust 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 Trust should fail to qualify under Subchapter M of the Code for tax treatment as a RIC, the Trust 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 Trust’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

S-60

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 Trust would be required to distribute to shareholders its earnings and profits attributable to non-RIC years. In addition, if the Trust 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 Trust 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 Trust 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 Trust qualifies for taxation as a RIC.

The Trust’s Investments

Certain of the Trust’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 Trust 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 Trust 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 Trust as a RIC. Additionally, the Trust may be required to limit its activities in derivative instruments in order to enable it to maintain its RIC status.

The Trust 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 Trust. U.S. federal income tax rules are not entirely clear about issues such as when the Trust 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 Trust’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.

S-61

securities or the income from such securities differs from the tax treatment expected by the Trust, it could affect the timing or character of income recognized by the Trust, potentially requiring the Trust to purchase or sell securities, or otherwise change its portfolio, in order to comply with the tax rules applicable to RICs under the Code.

Because the Trust may invest in foreign securities, its income from such securities may be subject to non-U.S. taxes.

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.

Options on indices of securities and sectors of securities that qualify as “section 1256 contracts” will generally be treated as “marked-to-market” for U.S. federal income tax purposes. As a result, the Trust 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 Trust to recognize gain in advance of the receipt of cash, the Trust 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.

Taxation of Common Shareholders

Trust distributions of its tax-exempt interest on municipal securities, if properly reported by the Trust to its shareholders (“exempt-interest dividends”), will generally be exempt from regular federal income tax. In order for the Trust to pay exempt-interest dividends, at least 50% of the value of the Trust’s total assets must consist of tax-exempt obligations on a quarterly basis. Although the Trust intends to meet this requirement, no assurance can be given in this regard. If the Trust failed to do so, it would not be able to pay tax-exempt dividends, and your distributions attributable to interest received by the Trust from any source (including distributions of tax-exempt interest income) would be taxable as ordinary income to the extent of the Trust’s earnings and profits.

S-62

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 Trust 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).

Distributions paid to you by the Trust from its net capital gain, if any, that the Trust 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 Trust (including dividends from net short-term capital gains) from its current or accumulated earnings and profits, other than exempt-interest dividends (“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 Trust) may qualify (i) for the dividends received deduction in the case of corporate shareholders to the extent that the Trust’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 Trust 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 Trust’s distributions will constitute qualified dividend income or be eligible for the dividends received deduction.

S-63

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 Trust 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 Trust.

If the Trust conducts a tender offer for its shares, a repurchase by the Trust 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 Trust repurchases, all of such shareholder’s shares, thereby reducing the shareholder’s percentage ownership of the Trust, 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 Trust 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 Trust, which determination depends on a particular shareholder’s facts and circumstances.

If a tendering shareholder’s proportionate ownership of the Trust (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 Trust 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 Trust to such shareholder for the shares sold, and will be taxable as a dividend, i.e., as ordinary income, to the extent of the Trust’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 Trust 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 Trust 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 Trust 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 Trust’s cash to repurchase shares may adversely affect the Trust’s ability to satisfy the distribution requirements for treatment as a regulated investment company described above. The Trust may also recognize

S-64

income in connection with the sale of portfolio securities to fund share purchases, in which case the Trust would take any such income into account in determining whether such distribution requirements have been satisfied.

If the Trust 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 Trust 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 Trust.

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.

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 Trust 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 tax even if the Trust 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 Trust’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 Trust held by or through certain foreign financial institutions (including investment funds), unless such institution

S-65

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 Trust are held will affect the determination of whether such withholding is required. Similarly, dividends paid in respect of common shares of the Trust 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 Trust 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 Trust’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 IRS.

Under U.S. Treasury regulations, if a common shareholder recognizes a loss with respect to common shares of $2 million or more for an individual shareholder in a single taxable year (or $4 million or more in any combination of taxable years in which the transaction is entered into and the five succeeding taxable years) or $10 million or more for a corporate shareholder in any single taxable year (or $20 million or more in any combination of taxable years in which the transaction is entered into and the five succeeding taxable years), the shareholder must file with the IRS a disclosure statement on IRS Form 8886. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Common shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

***

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 Trust 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 Trust 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 Trust and the income tax consequences to its holders of common shares.

APPENDIX A

Description of Bond Ratings

A rating is generally assigned to a fixed-income security at the time of issuance by a credit rating agency designated as a nationally recognized statistical rating organization (“NRSRO”) by the SEC. While NRSROs may from time to time revise such ratings, they undertake no obligation to do so, and the ratings given to securities at issuance do not necessarily represent ratings which would be given to these securities on a particular subsequent date.

NRSROs may rate specific investments (e.g., bonds), issuers (e.g., corporations, governments and financial institutions) and/or programs (e.g., commercial paper programs). However, certain types of investments may not be rated by NRSROs, such as certain government/sovereign obligations, US agency securities, commercial paper, time deposits at financial institutions, and derivative instruments such as credit default swaps. For these types of investments, as well as US Treasury securities (some of which are not rated), where a NRSRO has not rated the specific investment but has rated the investment’s issuer, program, financial institution or underlying reference asset, BlackRock Advisors, LLC, BlackRock Fund Advisors or their respective affiliates (“BlackRock”) may consider the investment to have the same NRSRO rating as its issuer, program, financial institution or underlying reference asset, as applicable. In the case of municipal securities, where one NRSRO provides multiple ratings for the same security (e.g., “underlying,” “insured” and/or “enhanced” ratings), BlackRock may consider the security to have the highest of the multiple ratings.

New issue securities (regardless of type) may not be rated by a NRSRO at the time of their initial offering. Preliminary prospectuses or term sheets for new issue securities may include an expected rating for the security (as determined by the underwriter and/or issuer) or a NRSRO rating for the issuer of the security. If applicable, when deciding whether to purchase a new issue security that has not yet been rated by a NRSRO, BlackRock may attribute an expected rating to the security based on: (i) the expected rating of the security set forth in the preliminary prospectus or term sheet for the security; (ii) the NRSRO’s rating for the issuer of the security set forth in the preliminary prospectus or term sheet for the security; or (iii) with respect to asset-backed securities, the rating of a prior issuance having a similar structure or the same sponsor.

Where the investment objective of a fund is to track the performance of an index that includes credit ratings eligibility criteria as part of its index methodology, the fund may purchase any security within the index, such security having been determined by the index provider as meeting its credit ratings eligibility criteria. The credit ratings practices of an index provider may differ from BlackRock’s practices, as described above. Further, the fund may invest, directly or indirectly, in securities that are not rated by a rating agency or securities with a credit rating that differs from the credit rating specified in its index methodology in various circumstances, including where a security is downgraded but not yet removed from an index, following the removal of a security from an index prior to its sale by the fund or as a result of a corporate action or restructuring affecting an issuer of a security held by the fund.

Fixed-income securities which are unrated may expose the investor to risks with respect to capacity to pay interest or repay principal which are similar to the risks of lower-rated speculative bonds. Evaluation of these securities is dependent on BlackRock’s judgment, analysis and experience in the evaluation of such securities.

Investors should note that the assignment of a rating to a security by an NRSRO may not reflect the effect of recent developments on the issuer’s ability to make interest and principal payments or on the likelihood of default.

Securities deemed to be high yield are rated below Baa3 by Moody’s and below BBB- by S&P Global Ratings and Fitch.

The descriptions below relate to general long-term and short-term obligations of an issuer.

A-1

A Description of Moody’s Investors Service, Inc.’s (“Moody’s”) Global Rating Scales

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. Moody’s defines credit risk as the risk that an entity may not meet its contractual financial obligations as they come due and any estimated financial loss in the event of default or impairment. The contractual financial obligations addressed by Moody’s ratings are those that call for, without regard to enforceability, the payment of an ascertainable amount, which may vary based upon standard sources of variation (e.g., floating interest rates), by an ascertainable date. Moody’s rating addresses the issuer’s ability to obtain cash sufficient to service the obligation, and its willingness to pay. Moody’s ratings do not address non-standard sources of variation in the amount of the principal obligation (e.g., equity indexed), absent an express statement to the contrary in a press release accompanying an initial rating. 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 for 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. Moody’s issues ratings at the issuer level and instrument level on both the long-term scale and the short-term scale. Typically, ratings are made publicly available although private and unpublished ratings may also be assigned.

Moody’s differentiates structured finance ratings from fundamental ratings (i.e., ratings on nonfinancial corporate, financial institution, and public sector entities) on the global long-term scale by adding (sf) to all structured finance ratings. The addition of (sf) to structured finance ratings should eliminate any presumption that such ratings and fundamental ratings at the same letter grade level will behave the same. The (sf) indicator for structured finance security ratings indicates that otherwise similarly rated structured finance and fundamental securities may have different risk characteristics. Through its current methodologies, however, Moody’s aspires to achieve broad expected equivalence in structured finance and fundamental rating performance when measured over a long period of time.

Description of Moody’s Global Long-Term Rating Scale

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.

A-2

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.

Description of Moody’s Global Short-Term Rating Scale

P-1	Ratings of Prime-1 reflect a superior ability to repay short-term obligations.

P-2	Ratings of Prime-2 reflect a strong ability to repay short-term obligations.

P-3	Ratings of Prime-3 reflect 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.

Description of Moody’s U.S. Municipal Short-Term Debt and Demand Obligation Ratings

Description of Moody’s Short-Term Obligation Ratings

Moody’s uses the global short-term Prime rating scale for commercial paper issued by U.S. municipalities and nonprofits. These commercial paper programs may be backed by external letters of credit or liquidity facilities, or by an issuer’s self-liquidity.

For other short-term municipal obligations, Moody’s uses one of two other short-term rating scales, the Municipal Investment Grade (“MIG”) and Variable Municipal Investment Grade (“VMIG”) scales discussed below.

Moody’s uses the MIG scale for U.S. municipal cash flow notes, bond anticipation notes and certain other short-term obligations, which typically mature in three years or less. Under certain circumstances, Moody’s uses the MIG scale for bond anticipation notes with maturities of up to five years.

MIG Scale

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.

A-3

Description of Moody’s Demand Obligation Ratings

In the case of variable rate demand obligations (“VRDOs”), a two-component rating is assigned. The components are a long-term rating and a short-term demand obligation rating. The long-term rating addresses the issuer’s ability to meet scheduled principal and interest payments. The short-term demand obligation rating addresses the ability of the issuer or the liquidity provider to make payments associated with the purchase-price-upon-demand feature (“demand feature”) of the VRDO. The short-term demand obligation rating uses the VMIG scale. VMIG ratings with liquidity support use as an input the short-term Counterparty Risk Assessment of the support provider, or the long-term rating of the underlying obligor in the absence of third party liquidity support. Transitions of VMIG ratings of demand obligations with conditional liquidity support differ from transitions on the Prime scale to reflect the risk that external liquidity support will terminate if the issuer’s long-term rating drops below investment grade.

Moody’s typically assigns the VMIG short-term demand obligation rating if the frequency of the demand feature is less than every three years. If the frequency of the demand feature is less than three years but the purchase price is payable only with remarketing proceeds, the short-term demand obligation rating is “NR”.

VMIG Scale


VMIG1		This designation denotes superior credit quality. Excellent protection is afforded by the superior short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.

VMIG2		This designation denotes strong credit quality. Good protection is afforded by the strong short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.

VMIG3		This designation denotes acceptable credit quality. Adequate protection is afforded by the satisfactory short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.

SG		This designation denotes speculative-grade credit quality. Demand features rated in this category may be supported by a liquidity provider that does not have a sufficiently strong short-term rating or may lack the structural or legal protections necessary to ensure the timely payment of purchase price upon demand.

Description of S&P Global Ratings (“S&P”), a Division of S&P Global Inc., Issue Credit Ratings

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 issue credit ratings are generally assigned to those obligations considered short-term in the relevant market, typically with an original maturity of no more than 365 days. Short-term issue credit ratings are also used to indicate the creditworthiness of an obligor with respect to put features on long-term obligations. S&P would typically assign a long-term issue credit rating to an obligation with an original maturity of greater than 365 days. However, the ratings S&P assigns to certain instruments may diverge from these guidelines based on market practices. Medium-term notes are assigned long-term ratings.

A-4

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

•

The likelihood of payment—the capacity and willingness of the obligor to meet its financial commitments on an obligation in accordance with the terms of the obligation;

•

The nature and provisions of the financial obligation, and the promise S&P imputes; and

•

The protection afforded by, and relative position of, the financial obligation in the event of a bankruptcy, reorganization, or other arrangement under the laws of bankruptcy and other laws affecting creditors’ rights.

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.)

Long-Term Issue Credit Ratings*


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.

A-5


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 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 debt restructuring.

* 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.

Short-Term Issue Credit Ratings


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 debt restructuring.

Description of S&P’s Municipal Short-Term Note Ratings

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:

•

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

A-6

•

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

S&P’s

municipal short-term note rating symbols are as follows:


SP-1		Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus (+) designation.

SP-2		Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

SP-3		Speculative capacity to pay principal and interest.

D		‘D’ is assigned upon failure to pay the note when due, completion of a distressed debt restructuring, or the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions.

Description of Fitch Ratings’ (“Fitch’s”) Credit Ratings Scales

Fitch Ratings publishes opinions on a variety of scales. The most common of these are credit ratings, but the agency also publishes ratings, scores and other relative opinions relating to financial or operational strength. For example, Fitch also provides specialized ratings of servicers of residential and commercial mortgages, asset managers and funds. In each case, users should refer to the definitions of each individual scale for guidance on the dimensions of risk covered in each assessment.

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 relating to securities and obligations of an issuer can include a recovery expectation. 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. The agency’s credit ratings cover the global spectrum of corporate, sovereign financial, bank, insurance, and public finance entities (including supranational and sub-national entities) and the securities or other obligations they issue, as well as structured finance securities backed by receivables or other financial assets.

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.

For the convenience of investors, Fitch may also include issues relating to a rated issuer that are not and have not been rated on its web page. Such issues are also denoted as ‘NR’.

Credit ratings express risk in relative rank order, which is to say they are ordinal measures of credit risk and are not predictive of a specific frequency of default or loss. For information about the historical performance of ratings please refer to Fitch’s Ratings Transition and Default studies which detail the historical default rates and their meaning. The European Securities and Markets Authority also maintains a central repository of historical default rates.

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).

A-7

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 primary credit rating scales can be used to provide a rating of privately issued obligations or certain note issuance programs or for private ratings. In this case the rating is not published, but only provided to the issuer or its agents in the form of a rating letter.

The primary credit rating scales may also be used to provide ratings for a more narrow scope, including interest strips and return of principal or in other forms of opinions such as credit opinions or rating assessment services. Credit opinions are either a notch- or category-specific view using the primary rating scale and omit one or more characteristics of a full rating or meet them to a different standard. Credit opinions will be indicated using a lower case letter symbol combined with either an ‘*’ (e.g. ‘bbb+*’) or (cat) suffix to denote the opinion status. Credit opinions will be point-in-time typically but may be monitored if the analytical group believes information will be sufficiently available. Rating assessment services are a notch-specific view using the primary rating scale of how an existing or potential rating may be changed by a given set of hypothetical circumstances. While credit opinions and rating assessment services are point-in-time and are not monitored, they may have a directional watch or outlook assigned, which can signify the trajectory of the credit profile.

Description of Fitch’s Long-Term Corporate Finance Obligations Rating Scales

Ratings of individual securities or financial obligations of a corporate issuer address relative vulnerability to default on an ordinal scale. In addition, for financial obligations in corporate finance, a measure of recovery given default on that liability is also included in the rating assessment. This notably applies to covered bonds ratings, which incorporate both an indication of the probability of default and of the recovery given a default of this debt instrument. On the contrary, Ratings of debtor-in-possession (“DIP”) obligations incorporate the expectation of full repayment.

The relationship between the issuer scale and obligation scale assumes a generic historical average recovery. Individual obligations can be assigned ratings higher, lower, or the same as that entity’s issuer rating or issuer default rating (“IDR”), based on their relative ranking, relative vulnerability to default or based on explicit Recovery Ratings.

As a result, individual obligations of entities, such as corporations, are assigned ratings higher, lower, or the same as that entity’s issuer rating or IDR, except DIP obligation ratings that are not based off an IDR. At the lower end of the ratings scale, Fitch publishes explicit Recovery Ratings in many cases to complement issuer and obligation ratings.

Fitch long-term obligations rating scales are as follows:


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

AA		Very High Credit Quality. ‘AA’ ratings denote expectations of very low credit risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A		High Credit Quality. ‘A’ ratings denote expectations of low credit risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.

BBB		Good Credit Quality. ‘BBB’ ratings indicate that expectations of credit risk are currently low. The capacity for payment of financial commitments is considered adequate, but adverse business or economic conditions are more likely to impair this capacity.

A-8



BB		Speculative. ‘BB’ ratings indicate an elevated vulnerability to credit risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial alternatives may be available to allow financial commitments to be met.

B		Highly Speculative. ‘B’ ratings indicate that material credit risk is present.

CCC		Substantial Credit Risk. ‘CCC’ ratings indicate that substantial credit risk is present.

CC		Very High Levels of Credit Risk. ‘CC’ ratings indicate very high levels of credit risk.

C		Exceptionally High Levels of Credit Risk. ‘C’ indicates exceptionally high levels of credit risk.

Within rating categories, Fitch may use modifiers. The modifiers “+” or “-” may be appended to a rating to denote relative status within major rating categories.

For example, the rating category ‘AA’ has three notch-specific rating levels (‘AA+’; ‘AA’; ‘AA–’; each a rating level). Such suffixes are not added to ‘AAA’ ratings and ratings below the ‘CCC’ category. For the short-term rating category of ‘F1’, a ‘+’ may be appended.

Description of Fitch’s Short-Term Ratings Assigned to Issuers and Obligations

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.

Fitch short-term ratings are as follows:


F1		Highest Short-Term Credit Quality. Indicates the strongest intrinsic capacity for timely payment of financial commitments; may have an added “+” to denote any exceptionally strong credit feature.

F2		Good Short-Term Credit Quality. Good intrinsic capacity for timely payment of financial commitments.

F3		Fair Short-Term Credit Quality. The intrinsic capacity for timely payment of financial commitments is adequate.

B		Speculative Short-Term Credit Quality. Minimal capacity for timely payment of financial commitments, plus heightened vulnerability to near term adverse changes in financial and economic conditions.

C		High Short-Term Default Risk. Default is a real possibility.

RD		Restricted Default. Indicates an entity that has defaulted on one or more of its financial commitments, although it continues to meet other financial obligations. Typically applicable to entity ratings only.

D		Default. Indicates a broad-based default event for an entity, or the default of a short-term obligation.

Closed-End Fund Proxy Voting Policy

Procedures Governing Delegation of Proxy Voting to Fund Adviser

Effective Date: January 1, 2025

Applies to the following types of Funds registered under the 1940 Act:

☐ Index Equity Mutual Funds and Exchange-Traded Funds

☐ Open-End Active and Fixed Income Index Mutual Funds and Exchange-Traded Funds

☐ Money Market Funds

☒ Closed-End Funds

☐ Other

Objective and Scope

Set forth below is the Closed-End Fund Proxy Voting Policy.

Policy / Document Requirements and Statements

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 the responsibility to vote proxies 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 the BlackRock Active Investment Stewardship Global Engagement and Voting Guidelines (as from time to time amended, the “Guidelines”) governing proxy voting by accounts managed by BlackRock.

BlackRock will cast votes on behalf of each of the Funds covered by this policy on specific proxy issues in respect of securities held by each such Fund (or may refrain from voting) in accordance with the 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.

Conflicts Management

BlackRock Active Investment Stewardship (“BAIS”) maintains policies and procedures that seek to prevent undue influence on BlackRock’s proxy voting activity and to mitigate material conflicts of interest in the

B-1

exercise of proxy voting responsibilities. Potential material conflicts, and the resultant potential for undue influence, might be due to a relationship between the investee company (or any shareholder proponent or dissident shareholder) and BlackRock, BlackRock’s affiliates or employees, or a Fund or a Fund’s affiliates. BlackRock has taken certain steps to mitigate potential conflicts, which are outlined in detail in the Guidelines. In mitigating conflicts, BAIS will adhere to the Guidelines.

In certain instances, BAIS will engage an independent third-party voting service provider to make

proxy voting recommendations as a further safeguard to avoid potential conflicts of interest, to satisfy regulatory compliance requirements, or as may be otherwise required by applicable law.

With respect to the relationship between securities lending and proxy voting, shares on loan cannot be voted and BlackRock may determine to recall them for voting, as guided by BlackRock’s fiduciary responsibility to act in clients’ financial interests. The Guidelines set forth BlackRock’s approach to recalling securities on loan in connection with proxy voting.

Reports to the Board

BlackRock will report on an annual basis to the Directors on (1) a summary of the proxy voting process as applicable to the Funds covered by this Policy in the preceding year together with a representation that all votes were in accordance with the Guidelines (as modified pursuant to the immediately preceding paragraph), and (2) any material changes to the Guidelines, including material changes to conflicts management practices, that have not previously been reported.

Overview

This document provides high level guidance on how BlackRock Active Investment Stewardship (BAIS) views corporate governance matters that are commonly put to a shareholder vote, or on which investors engage with issuers.¹ BAIS works in partnership with BlackRock’s investment teams, excluding index equity², providing expertise on investment stewardship and engaging with companies alongside and on behalf of those teams when appropriate. The team is responsible for establishing voting guidelines for the active equity platform, providing vote recommendations and operationalizing voting decisions. The guidance informs the voting recommendations BAIS makes to BlackRock’s active portfolio managers. It applies to active equity holdings in BlackRock’s fundamental equity, systematic equity and multi-asset solutions strategies. It also may apply to holdings in BlackRock’s index and active fixed income strategies, to the extent those strategies hold voting securities or conduct issuer engagements. The guidelines are not prescriptive as active portfolio managers have discretion as to how they integrate these guidelines within their investment processes in light of their clients’ or funds’ investment objectives. There are separate, independently developed principles and voting policies that are applied to BlackRock’s index equity investments by a distinct and independent function, BlackRock Investment Stewardship.

¹ This document includes BAIS’ benchmark policy, which covers nearly all active equity holdings in BlackRock’s fundamental equity, systematic equity and multi-asset solutions strategies. The benchmark policy also may apply to holdings in BlackRock’s index and active fixed income strategies, to the extent those strategies hold voting securities or conduct issuer engagements. This document also includes BAIS’ decarbonization policy, which covers holdings in BlackRock active funds that have climate and decarbonization objectives in addition to financial objectives.

² BlackRock segmented active and index equity investment functions, including stewardship, in January 2025 as part of a strategic initiative to unlock the full breadth of the firm’s active and private markets capabilities for clients. As a result, there are two stewardship teams, which operate independently of one another and have separate voting policies.

Introduction to BlackRock

BlackRock’s mission is to help more people invest better. The money BlackRock manages is not its own — it belongs to BlackRock’s clients, many of whom make their own asset allocation and portfolio construction decisions. As a fiduciary, BlackRock invests on clients’ behalf to help them meet their investment objectives. The firm does this by understanding clients’ long-term investment objectives and offering choice on how and where they wish to invest their money. BlackRock then helps clients seek the best risk-adjusted returns based on those choices, underpinning this work with research, data and analytics.

At BlackRock, investment stewardship is core to our role as an asset manager and a fiduciary to our clients. As stewards of our clients’ assets, we engage with companies to discuss the corporate governance and business practices that, in our experience, support companies in delivering durable, risk-adjusted financial returns over time. We are committed to building strong relationships through constructive, ongoing dialogue with the boards and executive management of the companies in which our clients are invested.

About BlackRock Active Investment Stewardship

BlackRock Active Investment Stewardship (BAIS) is a specialist team within the Portfolio Management Group and manages BlackRock’s stewardship engagement and voting on behalf of clients invested in active strategies globally. BAIS is also responsible for engagement with issuers in index fixed income strategies, where appropriate. Our activities are informed by these Global Engagement and Voting Guidelines (the “Guidelines”) and insights from active investment analysts and portfolio managers, with whom we work closely in engaging companies and voting at shareholder meetings.

Engagement with public companies is the foundation of our approach to stewardship within fundamental active investing.³ Through direct dialogue with company leadership, we seek to understand their businesses and how they manage risks and opportunities to deliver durable, risk-adjusted financial returns. Portfolio managers and stewardship specialists may engage jointly or independently on material corporate governance matters. Our discussions focus on topics relevant to a company’s success over time, including governance and leadership, corporate strategy, capital structure and financial performance, operations and material sustainability-related risks, as well as macro-economic, geopolitical and sector dynamics. We aim to be constructive investors and are generally supportive of management teams that have a track record of financial value creation. We aim to build and maintain strong relationships with company leadership based on open dialogue and mutual respect.

Different active equity strategies may implement these voting guidelines differently, as a result of the latitude each portfolio manager has to make independent voting decisions on their holdings. For example, BAIS will generally vote the holdings in Systematic Active Equity portfolios in accordance with these guidelines. We provide voting recommendations to fundamental equity portfolio managers, who may determine to vote differently based on each portfolio’s investment objectives and strategy.

These guidelines discuss BAIS’ views on corporate governance topics on which we may engage with management teams and board directors⁴and on matters that routinely come to a shareholder vote. We recognize that accepted corporate governance norms can differ across markets, and believe these guidelines represent globally applicable elements of governance that support a company’s ability to

³ On February 11, 2025, the U.S. Securities and Exchange Commission (SEC) staff issued updated guidance for shareholders to maintain their eligibility to report their beneficial ownership under Schedule 13G of the Exchange Act. We comply fully with these requirements and do not engage with portfolio companies for the purpose, or with the effect, of changing or influencing control of the company.

⁴ References to the board, board directors or non-executive directors should be understood to include supervisory boards and their members, where relevant.

B-6

manage material risks and opportunities and deliver financial returns to investors. Generally, we believe companies should observe accepted corporate governance norms within their local markets or, particularly in markets without well-established norms, aspire to widely recognized international best practices. As one of many minority shareholders, BlackRock cannot – and does not try to – direct a company’s strategy or its implementation. We look to companies to provide disclosures that explain how their approach to corporate governance best aligns with the financial interests of their investors.

Our approach to stewardship within active equities

Voting at a company’s shareholder meeting is a right of share ownership and a core principle of corporate governance. The voting rights attached to clients’ holdings are an important mechanism for investors to express support for, or concern about, a company’s performance. As a fiduciary, BlackRock is legally required to make proxy voting determinations, on behalf of clients who have delegated voting authority to us, in a manner consistent with BlackRock’s contractual arrangements with clients and funds.

In general, we tend to support the recommendations of the board of directors and management. As indicated below, we may vote against management recommendations when we have concerns about how companies are serving the financial interests of our clients as their shareholders. BAIS takes a globally consistent approach to voting but considers the different corporate governance regulations and norms across markets. Votes are determined on a case-by-case basis, in the context of a company’s situation and the investment mandate we have from clients. Please see page 19 for more information about how we fulfill and oversee our investment stewardship responsibilities for BlackRock’s non-index equity strategies.⁵

Our approach to stewardship within fixed income

Although fixed income investors do not have the right to vote at shareholder meetings, issuer engagement is a component of fixed income investment strategies at BlackRock, particularly for those with sustainability objectives in addition to financial objectives. Most corporate governance-related fixed income engagements are undertaken in conjunction with the active investment stewardship team, and often active equity investors. In addition to the topics listed below, engagement with fixed income investment teams may help inform an issuer’s approach to structuring specialist issuances and the standard terms and information in bond documentation.

Boards of Directors

Roles and responsibilities

There is widespread consensus that the foundation of good corporate governance is an effective board of directors that is able to advise and supervise management in an independent and objective manner.⁶

We look to the board of directors (hereafter the “board”) to have an oversight role in the establishment and realization of a company’s strategy, purpose and culture. These constructs are interdependent and, when aligned, can better position a company to be resilient in the face of a changing business environment, help reduce the risks of corporate or employee misconduct, and attract and retain the caliber of workers necessary to deliver financial performance over time.

⁵ Non-index equity strategies include active equity holdings in BlackRock’s fundamental equity, systematic equity and multi-asset solutions strategies, as well as holdings in BlackRock’s index and active fixed income strategies, to the extent those strategies hold voting securities or conduct issuer engagements.

⁶ See the Corporate Governance Codes of Germany, Japan, and the UK, as well as the corporate governance principles of the US Business Roundtable as examples.

B-7

In overseeing the management of the company, the board ensures the necessary resources, policies and procedures are in place to help management meet its strategic objectives within an agreed risk tolerance.

One of the most important responsibilities of the board is to appoint, and remove as necessary, the chief executive officer (“CEO”). In addition, the board plays a meaningful role in monitoring the performance of the CEO and other key executives, determining executive compensation, ensuring a rigorous audit, overseeing strategy execution and risk management and engaging with shareholders, and other stakeholders, as necessary.

Composition and effectiveness

Appointment process

A formal and transparent process for identifying and appointing director candidates is critical to ensuring the board is composed of directors with the appropriate mix of skills and experience. Generally, the board or a sub-committee determines the general criteria given the company’s circumstances (e.g., sector, maturity, geographic footprint) and any additional criteria for a specific role being filled (e.g., financial expertise, industry track record). To inform the process, we encourage companies to review the skills and experience of incumbent directors to identify any gaps and whether the skills and experience of a director candidate would be additive. We welcome disclosures that explain how the board considered different skills and experience to ensure that the directors collectively can be effective in fulfilling their responsibilities. We assess a company’s board composition against that of its peer group and local market requirements.

Shareholders periodically vote to elect directors to serve on the board. We do not prescribe any particular board composition in our engagements or voting but seek to understand how well placed a board is to act in investors’ interests. We may vote against the election of the most senior independent director, or the chair of the relevant committee, where a company has not demonstrated it has an appointment process that results in a high functioning board with the appropriate complement of skills and experience amongst the directors to support strong financial performance over time. We may vote against newly nominated directors who do not seem to have the appropriate skills or experience to contribute to the board’s effectiveness.

Independence

Director independence from management, significant shareholders or other stakeholders (e.g., government or employees) is of paramount importance to the protection of the interests of minority shareholders such as BlackRock’s clients. We consider it good practice for at least half the directors to be independent and free from conflicts of interest or undue influence.⁷ This also helps to ensure that board committees are composed of a sufficient number of independent directors. Companies domiciled in markets with a higher threshold for board independence should meet those local requirements.

We may vote against the election of non-independent directors if the board does not have a sufficient balance of independence. We may also vote against the election of the chair of the committee responsible for board composition if this is a perennial issue.

⁷ Common impediments to independence may include but are not limited to: current or recent employment at the company or a subsidiary; being, or representing, a shareholder with a substantial shareholding in the company; interlocking directorships; lengthy tenure, and having any other interest, business, or other relationship which could, or could reasonably be perceived to, materially interfere with a director’s ability to act in the best interests of the company and shareholders.

B-8

Independent board leadership

Practices across markets differ, as do board structures, but we observe two main approaches to independent board leadership. One is a non-executive, independent chair of the board who is responsible for leading the board in the effective exercise of its duties. The other is a lead or senior independent director, who is responsible for coordinating with the other non-executive directors and working closely with the executive chair on the board agenda and other board procedures. In this case, the executive chair and the lead independent director work together to ensure the board is effectively fulfilling its responsibilities. In our view, the independent leader of the board, and/or the chair of a relevant committee, should be available to investors to discuss governance matters such as CEO succession, executive pay, and board performance. We look to boards to explain their board leadership model and how it serves the interests of shareholders.

We may vote against the election of the chair of the committee responsible for board composition if there is not an identified independent leader of the board with clear responsibilities for board performance. We may vote against the most senior independent director if the board has a policy of not engaging with shareholders.

Tenure and succession

In our view, it is good practice for boards to establish the length of time a director would normally be expected to serve, in line with market norms where those exist. We find it helpful when companies disclose their approach to director tenure particularly around the contributions of directors who have served for longer periods than typically provided for under local practice. In our experience, long-serving directors could become less independent given their long-term relationship with management and involvement in past board decisions.

Succession planning for board roles helps achieve the appropriate cadence of turnover that balances renewal through the regular introduction of directors with fresh perspectives and expertise with continuity through the retention of directors with long-term knowledge of the board and company.

In markets where there is not specific director tenure guidance from regulation or corporate governance best practices, we may vote against the election of the chair of the committee responsible for board composition if a company does not clearly disclose its approach to director tenure and board renewal. We may vote against the election of directors who have served for more years than is typical in markets with specific guidance, where the case for their continued service is not evident.

Capacity

To be effective and engaged, directors need to have the time and energy to commit to the role. In our view, an effective board will assess the ability of its members to maintain an appropriate focus on board matters and the company taking into consideration competing responsibilities. We recognize that board leadership roles vary across markets in responsibilities and required time commitment but note that they are generally more intensive than a standard directorship. We will take local norms and practices into consideration when making our voting determinations across markets.

We may vote against the election of directors who do not seem to have sufficient capacity to effectively fulfil their duties to the board and company.

B-9

Director elections

Regular election of directors, ideally annually, supports director accountability to shareholders. A classified board structure⁸ may be justified by a company when it needs consistency and stability during a time of transition, or on the basis of its business model (e.g., a non-operating company such as closed-end funds).

Shareholders should have the opportunity to evaluate nominated directors individually rather than in bundled slates. We look to companies to provide sufficient information on each director standing for election so that shareholders can assess their capabilities and suitability. We will generally not support the election of directors whose names and biographical details have not been disclosed sufficiently in advance of the shareholder meeting.

Each director’s appointment should be dependent on receiving a simple majority of the votes cast at the shareholder meeting. Where a company’s practices differ, we look to the board to provide a detailed explanation as to how its approach best serves investors’ interests.

We may vote for shareholder or management proposals seeking to establish annual election of directors and/or a simple majority vote standard for director elections. We may vote against all the directors standing for election as part of a single slate if we have concerns about the profile or performance of an individual director.

Committees

Many boards establish committees to focus on specific responsibilities of the board such as audit and risk, governance and human capital, and executive compensation, amongst other matters. We do not prescribe to companies what committees they should establish, but we seek to understand the board’s rationale for the committee structure it determines is appropriate. We note that, in some markets, regulation requires such committees. The responsibilities of each committee should be clear, and the board should ensure that all critical matters are assigned either to the full board or to one of the committees. It is helpful to investor understanding when the board discloses the structure, membership, proportion of independent directors, and responsibilities of each committee. The responsibilities we typically see assigned to the three most common committees include:

•

Audit and risk – oversight responsibilities for the integrity of financial reporting, risk management and compliance with legal and regulatory requirements; may also play an oversight role in relation to the internal audit function and whistleblowing mechanisms.

•

Nominating, governance and human capital – oversight responsibilities for corporate governance principles and practices of the company, including the periodic review of board performance; responsibility for succession planning for CEO and key board roles, as well as the director appointment process; may also have oversight responsibilities for human capital management strategies, including corporate culture and purpose.

•

Executive compensation – determines the compensation policies and programs for the CEO and other executive officers, approves annual awards and payments under the policies; may also have oversight responsibilities for firm-wide compensation policies.

We may vote against the election of the chair of the committee or other directors serving as committee members to convey concerns about how a committee has undertaken its responsibilities. We may vote against the election of the most senior non-executive director if there is not a clearly disclosed approach to board committees.

⁸ A classified board divides the directors into classes with different overlapping terms. As a result, only one class of directors stands for election in any one year.

B-10

Board and director evaluation

We consider it best practice for companies to conduct an annual review of the performance of the board, the committees, the chair and individual directors. Periodically, this review could be undertaken by an independent third party able to bring objective perspectives to the board on governance and performance. We encourage companies to disclose their approach to and the objectives of evaluations, including any changes made to the board’s approach as a result.

Access to independent advice

To support the directors in effectively fulfilling their duties to the company and shareholders, they should have access to independent advice. In certain circumstances, it may be helpful to boards to retain independent third parties to advise on critical matters. These might include new industry developments such as emergent and disruptive technology, operating events with material consequences for the company’s reputation and/or performance, or significant transactions. Board committees may similarly retain third parties to advise them on specialist matters such as audit, compensation and succession planning.

Executive compensation

Boards play an important role in establishing compensation arrangements that enable the company to recruit, retain and reward the caliber of executive management necessary to lead and operate the company to deliver superior financial returns over time. We focus on alignment between variable pay and a company’s financial performance.

Generally, executive compensation arrangements have four components: base salary, annual bonus that rewards performance against short-term metrics, incentives - most often share-based- that reward performance against long-term metrics, and pensions and benefits. In our observation, base salary, pensions and benefits are largely set relative to market norms and benchmarks. The annual bonus and share-based incentive, or variable pay plans, tend to be tailored to the company, its sector and long-term strategy, as well as the individuals the board is seeking to recruit and motivate.

Recognizing the unique circumstances of each company, we determine whether to support a company’s approach to executive compensation on a case-by-case basis. We rely on companies providing sufficient quantitative and qualitative information in their disclosures to enable shareholders to understand the compensation arrangements and assess the alignment with investors’ interests. Features we look for in compensation arrangements include:

•

Fixed pay components, including base salary, benefits and prerequisites that are appropriate in the context of the company’s size, sector and market.

•

Variable pay subject to performance metrics that are closely linked to the company’s short- and long-term strategic objectives.

•

Long-term incentives that motivate sustained performance across a multi-year period.

•

A balance between fixed and variable pay, short- and long-term incentives, and specific instruments (cash and equity awards) that promotes pay program durability and seldom necessitates one-off, discretionary payments.

•

Pay outcomes that are consistent with the returns to investors over the relevant time period.

B-11

•

Board discretion, if allowed within the variable pay arrangements, to be used sparingly, responsibly and transparently.

•

A requirement, that participants in long-term share-based incentive plans build a meaningful shareholding in the company within a defined time period, as determined by the board or relevant board committee.

•

Change of control provisions that appropriately balance the interests of executives and shareholders.

•

Clawback or malus provisions that allow the company to recoup or hold back variable compensation from individuals whose awards were based on fraudulent activities, misstated financial reports, or executive misconduct.

•

Severance arrangements that protect the company’s interests but do not cost more than is contractual.

We may vote against proposals to introduce new share-based incentives, approve existing policies or plans, or approve the compensation report where we do not see alignment between executive compensation arrangements and our clients’ financial interests. When there is not an alternative, or where there have been multi-year issues with compensation misaligned with performance, we may vote against the election of the chair of the responsible committee, or the most senior independent director.

Non-executive director compensation

Companies generally pay non-executive directors an annual retainer or fee in cash, shares or a combination of the two. Some companies also pay additional fees for service on board committees or in board leadership roles. We do not support non-executive directors participating in performance-based incentive plans as doing so may create a conflict of interest and undermine their independence from management, whom they oversee.

Capital structure

Boards are responsible for ensuring senior executive leadership has established a capital strategy that achieves appropriate capital allocation in support of long-term financial resilience.

Where company practices diverge from those set out below, we look for companies to disclose why they view these practices to be aligned with shareholders’ interests. We may vote against management proposals seeking capital-related authorities, or the election of the most senior independent director, if we have concerns about a company’s approach. We may also support a shareholder proposal seeking conversion of shares with differentiated voting rights to a one-share, one-vote standard.

Share issuance

We assess requests for share issuance for particular transactions on a case-by-case basis. We will generally support authorities to issue shares when subject to pre-emptive rights, and up to 20% absent pre-emptive rights. We consider it good practice for companies to seek regular approval of these authorities to allow shareholders to take into consideration how prior authorities were used, as well as the current circumstances of the company and the market environment.

B-12

Share buybacks

We assess share buyback proposals in the context of the company’s disclosed capital management strategy and management’s determination of the appropriate balance between investment that supports the long-term growth of the company and returning cash to investors. We also take into consideration the effect of a buyback program on the company’s balance sheet and executive compensation arrangements and the price at which shares are repurchased relative to market price. We consider it good practice for companies to seek regular approval of these authorities to allow shareholders to take into consideration how prior authorities were used, as well as the current circumstances of the company and the market environment.

Dividends

We generally defer to management and the board on dividend policy but may engage to seek further clarification where a proposed dividend appears out of line with the company’s financial position.

Differentiated voting rights

We prefer companies to adopt a one-share, one-vote structure for share classes with the same economic exposure. Certain companies, particularly those new to public markets, could make the case to adopt a differentiated voting rights structure, or dual class stock. In those situations, we encourage companies to evaluate and seek approval for their capital structure on a periodic basis.

Transactions and special situations

We monitor developments in transactions and special situations closely and undertake our own detailed analyses of proposals.

Mergers and acquisitions

We evaluate proposed mergers or acquisitions by assessing the financial outcome for our clients as minority shareholders. Management should provide an assessment of the proposed transaction’s strategic and financial rationale, along with its execution and operational risks. We review each transaction independently based on these factors and the degree to which the transaction enhances shareholder value. The board might consider establishing an ad hoc transaction committee to undertake an independent assessment of a significant merger or acquisition, in advance of making its recommendation to shareholders.

We will vote against transactions that, in our assessment, do not advance our clients’ financial interests.

Anti-takeover defenses

In principle, we do not support companies using anti-takeover defenses, also known as poison pills or shareholder rights plans, as they can entrench management and boards which have not delivered long-term shareholder value. By exception, a poison pill may be supported if its purpose is to delay a takeover that is considered sub-optimal and enable management to seek an improved offer. Similarly, management could make the case to use a poison pill to block a shareholder activism campaign that may be counter to the interests of other investors. Defense mechanisms introduced in these circumstances should be limited in term and threshold, and also be closely monitored by the independent members of the board. We consider it good practice for companies to put to a shareholder vote any mechanisms expected to be in place for more than 12 months.

B-13

Shareholder activism

When companies are the focus of an activism campaign, we may communicate with the activist to understand their analysis and objectives, once they have publicly disclosed their campaign. We may also engage with company management and possibly board members, especially those the activist may be seeking to replace. In our assessment, we evaluate various factors, including the concerns raised by the activist and the case for change; the quality of both the activist’s and management’s plans; and the qualifications of each party’s candidates. We evaluate each contested situation by assessing the potential financial outcome for our clients as minority shareholders.

We may support board candidates nominated by a shareholder activist if BAIS, in its independent judgment, or the relevant portfolio manager has determined that there is a case for change to enhance shareholder value, or if the incumbent board members do not demonstrate the relevant skills and expertise or have a poor track record of protecting shareholders’ interests.

Significant shareholders and related party transactions

Boards of companies with affiliated shareholders or directors should give equitable consideration to the interests of all shareholders when evaluating related party transactions.

We consider it good practice for transactions with related parties, such as significant shareholders or companies affiliated with the public company, to be disclosed in detail and conducted on terms similar to what would objectively have been agreed with a non-related party. In our view, such transactions should be reviewed and approved by the independent members of the board, and if voted on, only disinterested shareholders should vote.

Corporate reporting, risk management and audit

Investors depend on corporate reporting, both regulatory and voluntary, to understand a company’s strategy, its implementation and financial performance, as well as to assess the quality of management and operations and potential for the company to create shareholder value over time. We consider it good practice for the board to oversee corporate reporting and the policies and procedures underpinning the internal audit function and external audit.

A company’s financial reporting should provide decision-useful information for investors, and other stakeholders, on its financial performance and position. It should provide an accurate and balanced assessment of the risks and opportunities the company faces in realizing its long-term strategy. Accordingly, the assumptions made by management and reviewed by the auditor in preparing the financial statements should be reasonable and justified. Financial statements should be prepared in accordance with globally developed reporting standards and any divergence from generally accepted accounting principles should be explained in detail and justified. Accounting restatements should be explained in detail and any remedial actions, and the implications of these, disclosed.

In this context, audit committees play a vital role in a company’s financial reporting system by providing independent oversight of the accounts, material financial and, where appropriate to the jurisdiction, non-financial information, internal control frameworks and Enterprise Risk Management systems. In our view, effective audit committee oversight strengthens the quality and reliability of a company’s financial statements and provides an important level of reassurance to shareholders. Audit committees should have a procedure in place for assessing the independence of the auditor and the quality of the external audit process annually.

B-14

Similarly, we encourage companies to disclose material sustainability-related factors that are integral to how a company manages risks or generates revenue. BAIS finds it helpful to our understanding when companies provide robust, standardized disclosures on their material sustainability-related risks and opportunities. The International Sustainability Standards Board (ISSB) is one entity working to meet these objectives through its reporting standards, which may be helpful to companies in preparing such reports.⁹ However, we do not mandate any specific disclosure framework, and note that companies in certain jurisdictions are subject to mandatory reporting requirements under standards specified by policy makers.¹⁰

Companies should establish robust risk management and internal control processes appropriate to the company’s business, risk tolerance, and regulatory environment. A credible whistleblowing system for employees, and potentially other stakeholders, can be a useful mechanism for ensuring that senior management and the board are aware of potential misconduct or breaches in risk management and internal control processes.

A comprehensive audit conducted by an independent audit firm contributes to investor confidence in the quality of corporate reporting. It is helpful when the audit report gives some insight into the scope and focus of the audit, as well as any critical audit matters identified and how these were resolved. A comprehensive and effective audit is time and resource intensive, and the audit fee should be commensurate. Fees paid to the audit firm for non-audit consulting should not exceed the audit fee to a degree that may prompt concerns about the independence of the audit. The audit committee should explain its position on auditor tenure and how it confirmed that the auditor remained independent.

We may vote against the election of the responsible directors if corporate reporting is insufficient or there are material misstatements in financial reports. In markets where relevant, we may vote against a proposal to approve the financial statements or the discharge of the board when we are concerned about the quality of corporate reporting or the audit. We may vote against proposals to appoint the auditor, ratify the audit report, or approve the audit fee if we are concerned about the auditor’s independence, the quality of the audit, or there are material misstatements in financial reports and the board has not established reasonable remediation plans.

Shareholder rights and protections

General shareholder meetings

Companies normally have an annual general meeting of shareholders at which routine and non-routine items of business are discussed and voted on by shareholders in attendance or submitting proxy votes. Companies should disclose materials relevant to the shareholder meeting sufficiently in advance so that shareholders can take them into consideration in their voting decisions. Many companies offer shareholders the option of participating in the meeting virtually which, whilst welcome, should not limit the rights of shareholders to participate as they would during an in-person meeting.

We may vote against directors when materials related to the business of the shareholder meeting are not provided in a timely manner or do not provide sufficient information for us to make an informed voting decision. We may vote against directors if the format of the shareholder meeting does not accommodate reasonable shareholder participation.

⁹ The ISSB is an independent standard-setting body within the International Financial Reporting Standards (IFRS) Foundation. Please refer to the IFRS website to learn more about the framework and standards S1 “General Requirements for Disclosure of Sustainability-related Financial Information” and S2 “Climate-related Disclosures.”

B-15

Bylaw amendments

We review bylaw amendments proposed by management on a case-by-case basis and will generally support those that are aligned with the interests of minority shareholders. Any material changes to the bylaws should be explained in detail and put to a shareholder vote.

We may vote against bylaw amendments that reduce shareholder rights and protections or introduce additional burdens. We may vote against directors if material changes are made to the bylaws without shareholder approval.

If not provided for in the relevant corporate law, company bylaws should allow shareholders, individually or as a group, with a meaningful shareholding, the right to call a special meeting of shareholders. The shareholding required to exercise this right should balance its utility with the cost to the company of holding special meetings.

If not provided for in the relevant corporate law, company bylaws should allow shareholders, individually or as a group, with a meaningful shareholding, the right to nominate directors to the company’s board. The threshold for this right should be set so that shareholders can exercise it without being unduly disruptive to the board’s own nomination process.

Whilst we would not use either of these rights ourselves, we see them as important accountability mechanisms. We may vote for a shareholder proposal seeking the addition of either of these provisions to a company’s bylaws.

Change of domicile

We generally defer to management on proposals to change a company’s domicile as long as the rationale for doing so is consistent with the company’s long-term strategy and business model and the related costs are immaterial.

We may vote against directors or a proposal to change a company’s domicile where it does not seem aligned with our clients’ financial interests.

Changes to a company’s purpose or the nature of its business

Plans to materially change the nature of a company’s business or its purpose should be disclosed and explained in the context of long-term strategy and business dynamics. Such changes may significantly alter an investor’s views on the suitability of a company for their investment strategy or portfolio.

Where relevant, we may vote against proposals to change a company’s purpose or the nature of its business if the board has not provided a credible argument for change.

Shareholder proposals

Shareholders in many markets, who meet certain eligibility criteria, have the right to submit proposals to the general shareholder meeting asking a company to take a particular course of action subject to the proposal being supported by a majority of votes cast at the meeting. The topics raised can address a range of matters that may be relevant to a company’s business.

We vote on these proposals on a case-by-case basis. We assess the relevance of the topic raised to a company’s business and its current approach, whether the actions sought are consistent with shareholders’ interests, and what impact the proposal being acted upon might have on financial performance.

B-16

Our general approach where we have concerns about a company’s governance, disclosures or performance is to engage to understand the apparent difference in perspective. If we are concerned a company is not acting in shareholders’ financial interests, we may vote against the election of directors. We may support a relevant shareholder proposal if doing so is aligned with our clients’ financial interests. We generally do not support shareholder proposals that are legally binding on the company, seek to alter a company’s strategy or direct its operations, or are unrelated to how a company manages risk or generates financial returns.

BlackRock is subject to rules, regulations, agency guidance and contractual agreements that place restrictions and limitations on how we can interact with the companies in which we invest on behalf of our clients, including our ability to submit shareholder proposals. We do not submit shareholder proposals but can vote, on behalf of clients who authorize us to do so, on proposals put forth by others.

Corporate political activities

A corporation’s ability to engage in the policy process is subject to rules and regulations set by the jurisdictions in which they engage. When a corporation reports material financial risk related to policy and or regulatory changes, BAIS may seek to understand how it is addressing the material risk identified. We seek to understand how companies engage in corporate political activities and ensure that their participation is consistent with their public statements on policy matters material to the company’s long-term strategy. The board should be aware of the approach taken by management on corporate political activities as there can be reputational risks arising from inconsistencies between a company’s policy engagement and stated policy positions. Companies should, as a minimum, meet all regulatory disclosure requirements on political activities. We may engage a company where we would like to better understand its approach to policy engagement, where relevant.

To mitigate the risk of inconsistencies, companies may wish to assess the alignment between their policy priorities and the policy positions of the trade associations of which they are active members and any engagements undertaken by trade associations on behalf of members.

We may support a relevant shareholder proposal, or vote against directors, where a company’s disclosures are insufficient to address the material risk it has identified.

Material sustainability-related risks and opportunities

We seek to understand how companies manage the material risks and opportunities inherent in their business operations. In our experience, sustainability-related factors¹¹ that are relevant to a company’s business or material to its financial performance, are generally operational considerations embedded into day-to-day management systems. Certain sustainability issues may also inform long-term strategic planning, for example, investing in product innovation in anticipation of changing consumer demand or adapting supply chains in response to changing regulatory requirements.

¹¹ By material sustainability-related risks and opportunities, we mean the drivers of risk and financial value creation in a company’s business model that have an environmental or social dependency or impact. Examples of environmental issues include, but are not limited to, water use, land use, waste management, and climate risk. Examples of social issues include, but are not limited to, human capital management, impacts on the communities in which a company operates, customer loyalty, and relationships with regulators. It is our view that well-managed companies will effectively evaluate and manage material sustainability-related risks and opportunities relevant to their businesses. Governance is the core means by which boards can oversee the creation of durable financial value over time. Appropriate risk oversight of business-relevant and material sustainability-related considerations is a component of a sound governance framework.

B-17

We recognize that the specific sustainability-related factors that may be financially material or business relevant will vary by company business model, sector, key markets, and time horizon, amongst other considerations. From company disclosures and our engagement, we aim to understand how management is identifying, assessing and integrating material sustainability-related risks and opportunities into their business decision-making and practices. Doing so helps us undertake a more holistic assessment of a company’s potential financial performance and the likely risk-adjusted returns of an investment.

We may vote against directors or support a relevant shareholder proposal if we have concerns about how a company is managing or disclosing its approach to material sustainability-related risks that may impact financial returns.

Key stakeholders

In our view, companies should understand and take into consideration the interests of the various parties on whom they depend for their success over time. It is for each company to determine their key stakeholders based on what is material to their business and long-term financial performance. For many companies, key stakeholders include employees, business partners (such as suppliers and distributors), clients and consumers, regulators, and the communities in which they operate. Companies that appropriately balance the interests of investors and other stakeholders are, in our experience, more likely to be financially resilient over time.

B-18

Climate and decarbonization investment objectives

Certain active BlackRock funds have climate and decarbonization objectives in addition to financial objectives. Consistent with the objectives of those investment strategies, our stewardship activity in relation to the holdings in those funds differs in some respects from BAIS’ benchmark guidelines, which are described above. Specifically, for those funds’ holdings, we look to investee companies to demonstrate that they are aligned with a decarbonization pathway that means their business model would be viable in a low-carbon economy, i.e., one in which global temperature rise is limited to 1.5°C above pre-industrial levels. In addition, clients in separately managed accounts may instruct BlackRock to apply these guidelines to their holdings. Both in the case of funds and separately managed accounts, these guidelines are only implemented upon explicit selection and approval by the applicable fund board or client.

These decarbonization stewardship guidelines focus on companies which produce goods and services that contribute to real world decarbonization or have a carbon intensive business model and face outsized impacts from the low carbon transition, based on reported and estimated scopes 1, 2, and 3 greenhouse gas emissions. These companies should provide disclosures that set out their governance, strategy, risk management processes and metrics and targets relevant to decarbonization. It is helpful to investors’ understanding when these disclosures include an explanation of the decarbonization scenarios a company is using in its near- and long-term planning, as well as its scope 1, scope 2 and material scope 3 greenhouse gas (GHG) emissions and reduction targets for scope 1 and 2 emissions.

Under these climate- and decarbonization-specific guidelines, BAIS may recommend a vote against directors or support for a relevant shareholder proposal if a company does not appear to be adequately acting to address or disclosing material climate-related risks, consistent with the parameters set out in these climate- and decarbonization-specific guidelines. We may recommend supporting shareholder proposals seeking information relevant to a company’s stated low-carbon transition strategy or targets that the company does not currently provide and that would be helpful to investment decision-making. We would not recommend support for shareholder proposals that seek to constrain board or management decision-making or direct specific business or strategic decisions. As under the BAIS benchmark approach, the active portfolio managers are ultimately responsible for voting consistent with their investment mandate and fund objectives. For the funds and accounts in scope, voting on matters not related to climate risk and the energy transition is undertaken in line with BAIS’ benchmark guidelines.

B-19

Appendix 1: How we fulfil and oversee our investment stewardship responsibilities for non-index equity investment strategies

Oversight

The Global Head of BAIS has primary oversight of and responsibility for the team’s activities, including voting in accordance with the BlackRock Active Investment Stewardship Global Engagement and Voting Guidelines (the “Guidelines”), which require the application of professional judgment and consideration of each company’s unique circumstances, as well as input from active investors. BAIS is independent from BlackRock Investment Stewardship in our engagement and voting activities, reporting lines, and oversight.

The Stewardship Leaders Group, comprised of senior active investors and other relevant stakeholders in BlackRock’s legal, public policy, sustainability and communications teams, helps shape the firm’s approach to investment stewardship on non-index equity investment strategies. The Group may advise on and review amendments to BAIS’ policies and practices. It does not determine voting decisions, which are the responsibility of BAIS and the relevant active equity investors.

BAIS carries out engagement with companies in collaboration with active investment colleagues, executes proxy votes, and conducts vote operations (including maintaining records of votes cast) in a manner consistent with the Guidelines. BAIS also conducts research on corporate governance issues and participates in industry discussions to contribute to and keep abreast of important developments in the corporate governance field. BAIS may use third parties for certain of the foregoing activities and performs oversight of those third parties (see “Use and oversight of third-party vote services providers” below).

Voting guidelines and vote execution

BlackRock votes on proxy issues when our clients authorize us to do so. We carefully consider the voting items submitted to funds and other fiduciary account(s) (Fund or Funds) for which we have voting authority. BlackRock votes (or refrains from voting) for each Fund for which we have voting authority based on our evaluation of the alignment of the voting items with the long-term economic interests of our clients, in the exercise of our independent business judgment, and without regard to the relationship of the issuer (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, BAIS will normally vote on specific proxy issues in accordance with the Guidelines, although portfolio managers have the right to vote differently on their holdings if they determine doing so is more aligned with the investment objective and financial interests of clients invested in the funds they manage.

The Guidelines are not intended to be exhaustive. BAIS 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, the Guidelines do not indicate how BAIS will vote in every instance. Rather, they reflect our view about corporate governance issues generally, and provide insight into how we typically approach issues that are commonly put to a shareholder vote. The Guidelines are reviewed annually and updated as necessary to reflect changes in market practices, developments in corporate governance and feedback from companies and clients. In this way, BAIS aims to maintain policies that explain our approach to governance practices most aligned with clients’ long-term financial interests.

B-20

In certain markets, proxy voting involves logistical issues which can affect BAIS’ 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 from the point at which votes are submitted until after the after the shareholder meeting has occurred); v) potential difficulties in translating the proxy; vi) regulatory constraints; and vii) requirements to provide local agents with powers of attorney to facilitate voting instructions. We are not supportive of impediments to the exercise of voting rights such as share-blocking or overly burdensome administrative requirements.

BlackRock votes proxies in these situations on a “best-efforts” basis. In addition, BAIS may determine that it is generally in the interests of BlackRock’s clients not to vote proxies (or not to vote our full allocation) if the costs (including but not limited to opportunity costs associated with share-blocking constraints) associated with exercising a vote are expected to outweigh the benefit the client would derive by voting on the proposal.

Voting Choice

BlackRock offers Voting Choice, a program that provides eligible clients with more opportunities to participate in the proxy voting process where legally and operationally viable.

Voting Choice is currently available for eligible clients invested in certain institutional pooled funds in the U.S., UK, and Canada that use systematic active equity (SAE) and multi-asset strategies. In addition, institutional clients in separately managed accounts (SMAs) are eligible for BlackRock Voting Choice regardless of their investment strategies.¹²

As a result, the shares attributed to BlackRock in company share registers may be voted differently depending on whether our clients have authorized BAIS to vote on their behalf, have authorized BlackRock to vote in accordance with a third-party policy, or have elected to vote shares in accordance with their own policy. Our clients have greater control over proxy voting because of Voting Choice.¹³

Use and oversight of third-party vote services providers

Third-party vote services providers – or proxy research firms - provide research and recommendations on proxy votes, as well as voting infrastructure. BlackRock contracts primarily with the vote services provider ISS and leverages its online platform to supply research and support voting, record keeping, and reporting processes. We also use Glass Lewis’ research and analysis as an input into our voting process. It is important to note that, although proxy research firms provide important data and analysis, BAIS does not rely solely on their information or follow their voting recommendations. A company’s disclosures, our engagements and voting, investment colleagues’ insights and our Guidelines are important inputs into our voting decisions on behalf of clients.

Given the large universe of actively held companies, BAIS employs the proxy services provider to streamline the voting process by making voting recommendations based on BAIS’ Guidelines when the items on a shareholder meeting agenda are routine. Agenda items that are not routine are referred back to BAIS to assess, escalate as necessary to the relevant portfolio managers and vote. BAIS reviews and can override the recommendations of the vote services provider at any time prior to the vote deadline. Both BAIS and the vote services provider actively monitor securities filings, research reports, company announcements, and direct communications from companies to ensure awareness of supplemental disclosures and proxy materials that may require a modification of votes.

¹² With Voting Choice, SMAs have the ability to select from a set of voting policies from third-party proxy advisers the policy that best aligns with their views and preferences. BlackRock can then use its proxy voting infrastructure to cast votes based on the client’s selected voting policy.

¹³ BlackRock does not disclose client information, including a client’s selection of proxy policy, without client consent.

B-21

BAIS closely monitors the third-party vote services providers we contract with to ensure that they are meeting our service level expectations and have effective policies and procedures in place to manage potential conflicts of interest. Our oversight of service providers includes regular meetings with client service teams, systematic monitoring of vendor operations, as well as annual due diligence meetings in accordance with BlackRock’s firmwide policies.

Conflicts management policies and procedures

BlackRock maintains policies and procedures that seek to prevent undue influence on BAIS’ 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 clients who may be issuers of securities or proponents of shareholder resolutions

•

BlackRock business partners or third parties who may be issuers of securities or proponents of shareholder resolutions

•

BlackRock employees who may sit on the boards of public companies held in Funds managed by BlackRock

•

Significant BlackRock, Inc. investors who may be issuers of securities held in Funds managed by BlackRock

•

Securities of BlackRock, Inc. or BlackRock investment funds held in Funds managed by BlackRock

•

BlackRock, Inc. board members who serve as senior executives or directors of public companies held in Funds managed by BlackRock

BlackRock has taken certain steps to mitigate perceived or potential conflicts including, but not limited to, the following:

•

Adopted these Guidelines which are designed to advance our clients’ long-term financial interests in the companies in which BlackRock invests on their behalf

•

Established a reporting structure that separates BAIS from employees with sales, vendor management, or business partnership roles. In addition, BlackRock seeks to ensure that all engagements with corporate issuers, dissident shareholders or shareholder proponents are managed consistently and without regard to BlackRock’s relationship with such parties. Clients or business partners are not given preferential treatment or differentiated access. BAIS prioritizes engagements based on factors including, but not limited to, our need for additional information to make a more informed voting decision or to better understand a company’s perspectives on financially material risks and opportunities. Within the normal course of business, BAIS may engage directly with BlackRock clients, business partners and/or third parties, and/or with employees with sales, vendor management, or business partnership roles, in discussions regarding our approach to stewardship, general corporate governance matters, client reporting needs, and/or to otherwise ensure that proxy-related client service levels are met

•

Determined to engage, in certain instances, an independent third-party voting service provider to make proxy voting recommendations as a further safeguard to avoid perceived or potential conflicts of interest, to satisfy regulatory requirements, or as may be otherwise required by applicable law. In such circumstances, the independent third-party voting service provider provides BlackRock with recommendations, in accordance with the Guidelines, as to how to vote such proxies. BlackRock uses an independent third-party voting service provider to make proxy

B-22

voting recommendations for shares of BlackRock, Inc. and companies affiliated with BlackRock, Inc. BlackRock may also use an independent third-party voting service provider to make proxy voting recommendations for certain perceived or potential conflicts of interest, including:

^○

public companies that include BlackRock employees on their boards of directors

^○

public companies of which a BlackRock, Inc. board member serves as a senior executive or a member of the board of directors

^○

public companies that are the subject of certain transactions involving BlackRock Funds

^○

public companies that are joint venture partners with BlackRock, and

^○

public companies when legal or regulatory requirements compel BlackRock to use an independent third-party voting service provider

In selecting an independent third-party voting service provider, we assess several characteristics, including but not limited to: independence, an ability to analyze proxy issues and make recommendations in the economic interest of our clients in accordance with the Guidelines, reputation for reliability and integrity, and operational capacity to accurately deliver the assigned recommendations in a timely manner. We may engage more than one independent third-party voting service provider, in part to mitigate potential or perceived conflicts of interest at a single voting service provider.

Securities lending

If authorized, BlackRock acts as a securities lending agent on behalf of its clients. Securities lending is a well-regulated practice that contributes to capital market efficiency. It also enables funds to generate additional returns which in turn may allow fund providers to offset fund expenses.

With regard to the relationship between securities lending and proxy voting, BlackRock cannot vote shares on loan and may determine to recall them to allow for voting. This decision is guided by our fiduciary duty as an asset manager to our clients in helping them achieve their investment goals. While this has occurred in a limited number of cases, the decision to recall securities on loan as part of BlackRock’s securities lending program in order to vote is based on an evaluation of various factors that include, but are not limited to, assessing potential securities lending revenue alongside the potential long-term financial value to clients of voting those securities (based on the information available at the time of recall consideration). BAIS works with active portfolio managers, as well as colleagues in the Securities Lending team, to evaluate the costs and benefits to clients of recalling shares on loan.

In almost all instances, BlackRock anticipates that the potential long-term financial value to clients of voting shares would not warrant recalling securities on loan. However, in certain instances, BlackRock may determine, in our independent business judgment as a fiduciary, that the value of voting outweighs the securities lending revenue loss to clients and would therefore recall shares to be voted in those instances.

Periodically, BlackRock reviews our process for determining whether to recall securities on loan in order to vote and may modify it as necessary.

Reporting and vote transparency

BAIS is committed to transparency in the stewardship work we do on behalf of clients. We inform clients about our engagement and voting policies and activities through direct communication and disclosure on our website.

Indemnification

Article V of the Registrant’s Agreement and Declaration of Trust provides as follows:

5.1 No Personal Liability of Shareholders, Trustees, etc. No Shareholder of the Trust shall be subject in such capacity to any personal liability whatsoever to any Person in connection with Trust Property or the acts,

obligations or affairs of the Trust. Shareholders shall have the same limitation of personal liability as is extended to stockholders of a private corporation for profit incorporated under the Delaware General Corporation Law. No Trustee or officer of the Trust shall be subject in such capacity to any personal liability whatsoever to any Person, other than the Trust or its Shareholders, in connection with Trust Property or the affairs of the Trust, save only liability to the Trust or its Shareholders arising from bad faith, willful misfeasance, gross negligence (negligence in the case of those Trustees or officers who are directors, officers or employees of the Trust’s investment advisor (“Affiliated Indemnitees”)) or reckless disregard for his duty to such Person; and, subject to the foregoing exception, all such Persons shall look solely to the Trust Property for satisfaction of claims of any nature arising in connection with the affairs of the Trust. If any Shareholder, Trustee or officer, as such, of the Trust, is made a party to any suit or proceeding to enforce any such liability, subject to the foregoing exception, he shall not, on account thereof, be held to any personal liability. Any repeal or modification of this Section 5.1 shall not adversely affect any right or protection of a Trustee or officer of the Trust existing at the time of such repeal or modification with respect to acts or omissions occurring prior to such repeal or modification.

5.2 Mandatory Indemnification. (a) The Trust hereby agrees to indemnify each person who at any time serves as a Trustee or officer of the Trust (each such person being an “indemnitee”) against any liabilities and expenses, including amounts paid in satisfaction of judgments, in compromise or as fines and penalties, and reasonable counsel fees reasonably incurred by such indemnitee in connection with the defense or disposition of any action, suit or other proceeding, whether civil or criminal, before any court or administrative or investigative body in which he may be or may have been involved as a party or otherwise or with which he may be or may have been threatened, while acting in any capacity set forth in this Article V by reason of his having acted in any such capacity, except with respect to any matter as to which he shall not have acted in good faith in the reasonable belief that his action was in the best interest of the Trust or, in the case of any criminal proceeding, as to which he shall have had reasonable cause to believe that the conduct was unlawful, provided, however, that 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 (negligence in the case of Affiliated Indemnitees), or (iv) reckless disregard of the duties involved in the conduct of his position (the conduct referred to in such clauses (i) through (iv) being sometimes referred to herein as “disabling conduct”). Notwithstanding the foregoing, 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 (1) was authorized by a majority of the Trustees or (2) 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. The rights to indemnification set forth in this Declaration shall continue as to a person who has ceased to be a Trustee or officer of the Trust and shall inure to the benefit of his or her heirs, executors and personal and legal representatives. No amendment or restatement of this Declaration or repeal of any of its provisions shall limit or eliminate any of the benefits provided to any person who at any time is or was a Trustee or officer of the Trust or otherwise entitled to indemnification hereunder in respect of any act or omission that occurred prior to such amendment, restatement or repeal.

(b) Notwithstanding the foregoing, 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 (1) a majority vote of a quorum of those Trustees who are neither “interested persons” of the Trust (as defined in Section 2(a)(19) of the 1940 Act) nor parties to the proceeding (“Disinterested Non-Party Trustees”), that the indemnitee is entitled to indemnification hereunder, or (2) if such quorum is not obtainable or even if obtainable, if such majority so directs, independent legal counsel in a written opinion concludes that the indemnitee should be entitled to indemnification hereunder. All determinations to make advance payments in connection with the expense of defending any proceeding shall be authorized and made in accordance with the immediately succeeding paragraph (c) below.

(c) The Trust shall make advance payments in connection with the expenses of defending any action with respect to which indemnification might be sought hereunder if the Trust receives a written affirmation by the indemnitee of the indemnitee’s good faith belief that the standards of conduct necessary for indemnification have been met and a written undertaking to reimburse the Trust unless it is subsequently determined that the

indemnitee is entitled to such indemnification and if a majority of the Trustees determine that the applicable standards of conduct necessary for indemnification appear to have been met. In addition, at least one of the following conditions must be met: (i) the indemnitee shall provide adequate security for his undertaking, (ii) the Trust shall be insured against losses arising by reason of any lawful advances, or(iii) a majority of a quorum of the Disinterested Non-Party Trustees, or if a majority vote of such quorum so direct, independent legal counsel in a written opinion, shall conclude, based on a review of readily available facts (as opposed to a full trial-type inquiry), that there is substantial reason to believe that the indemnitee ultimately will be found entitled to indemnification.

(d) The rights accruing to any indemnitee under these provisions shall not exclude any other right which any person may have or hereafter acquire under this Declaration, the By-Laws of the Trust, any statute, agreement, vote of stockholders or Trustees who are “disinterested persons” (as defined in Section 2(a)(19) of the 1940 Act) or any other right to which he or she may be lawfully entitled.

(e) Subject to any limitations provided by the 1940 Act and this Declaration, the Trust 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 Trust or serving in any capacity at the request of the Trust to the full extent corporations organized under the Delaware General Corporation Law may indemnify or provide for the advance payment of expenses for such Persons, provided that such indemnification has been approved by a majority of the Trustees.

5.3 No Bond Required of Trustees. No Trustee shall, as such, be obligated to give any bond or other security for the performance of any of his duties hereunder.

5.4 No Duty of Investigation; No Notice in Trust Instruments, etc. No purchaser, lender, transfer agent or other person dealing with the Trustees or with any officer, employee or agent of the Trust shall be bound to make any inquiry concerning the validity of any transaction purporting to be made by the Trustees or by said officer, employee or agent or be liable for the application of money or property paid, loaned, or delivered to or on the order of the Trustees or of said officer, employee or agent. Every obligation, contract, undertaking, instrument, certificate, Share, other security of the Trust, and every other act or thing whatsoever executed in connection with the Trust shall be conclusively taken to have been executed or done by the executors thereof only in their capacity as Trustees under this Declaration or in their capacity as officers, employees or agents of the Trust. The Trustees may maintain insurance for the protection of the Trust Property, its Shareholders, Trustees, officers, employees and agents in such amount as the Trustees shall

deem adequate to cover possible tort liability, and such other insurance as the Trustees in their sole judgment shall deem advisable or is required by the 1940 Act.

5.5 Reliance on Experts, etc. Each Trustee and officer or employee of the Trust shall, in the performance of its 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 Trust, upon an opinion of counsel, or upon reports made to the Trust by any of the Trust’s officers or employees or by any advisor, administrator, manager, distributor, selected dealer, accountant, appraiser or other expert or consultant selected with reasonable care by the Trustees, officers or employees of the Trust, regardless of whether such counsel or expert may also be a Trustee.

Registrant has also entered into an agreement with Trustees and officers of the Registrant entitled to indemnification under the Agreement and Declaration of Trust pursuant to which the Registrant has agreed to advance expenses and costs incurred by the indemnitee in connection with any matter in respect of which indemnification might be sought pursuant to the Agreement and Declaration of Trust to the maximum extent permitted by law.

Reference is also made to:

•

Sections 10 and 11 of the Registrant’s Investment Management Agreement, a form of which is filed as Exhibit (g)(1) of this Registration Statement.

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.

Item 31.

Business And Other Connections Of Investment Advisor

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 SEC pursuant to the Investment Advisers Act of 1940 (Commission File No. 801-47710).

Undertakings

(1)	Not applicable.

(2)	Not applicable.

(3)	The securities being registered will be offered on a delayed or continuous basis in reliance on Rule 415 under the Securities Act of 1933. Accordingly, the Registrant undertakes:

(a)

to file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(1) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(2) to reflect in the prospectus any facts or events after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

(3) to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement.

(b)

that for the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(c)

to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering; and

(d)

that, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(1) if the Registrant is relying on Rule 430B [17 CFR 230.430B]:

(A) Each prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (x), or (xi) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or

(2) if the Registrant is subject to Rule 430C [17 CFR 230.430C]: Each prospectus filed pursuant to Rule 424(b) under the Securities Act of 1933 as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(e)

that for the purpose of determining liability of the Registrant under the Securities Act of 1933 to any purchaser in the initial distribution of securities: The undersigned Registrant undertakes that in a primary offering of securities of the undersigned Registrant pursuant to this Registration Statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to the purchaser: (1) any preliminary prospectus or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424 under the Securities Act of 1933; (2) free writing prospectus relating to the offering prepared by or on behalf of the undersigned Registrant or used or referred to by the undersigned Registrant; (3) the portion of any other free writing prospectus or advertisement pursuant to Rule 482 under the Securities Act of 1933 relating to the offering containing material information about the undersigned Registrant or its securities provided by or on behalf of the undersigned Registrant; and (4) any other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.

(4)	If applicable:

(a)

For the purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of a registration statement in reliance upon Rule 430A and contained in the form of prospectus filed by the Registrant under Rule 424(b)(1) under

the Securities Act of 1933 shall be deemed to be part of the Registration Statement as of the time it was declared effective.

(b)

For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of the securities at that time shall be deemed to be the initial bona fide offering thereof.

(5)

The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference into the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 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 director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, 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 of 1933 and will be governed by the final adjudication of such issue.

(7)	The Registrant undertakes to send by first class mail or other means designed to ensure equally prompt delivery within two business days of receipt of a written or oral request, any prospectus or Statement of Additional Information.
