Index performance shown for illustrative purposes only. You cannot invest directly in an index. Subprime mortgage woes dominated headlines for much of 2007, but intensified in the summer and fall, spawning a widespread liquidity and credit crisis with ramifications across global markets. The Federal Reserve Board (the "Fed") and other countries' central banks stepped in to inject liquidity into the markets and bolster investor confidence. The Fed cut the federal funds rate by 0.50% in September and another 0.25% on the final day of the reporting period, bringing its target rate to 4.50%. In taking action, the central bankers, who had long deemed themselves inflation fighters, were seeking to stem the fallout from the credit crunch and forestall a wider economic unraveling. By period-end, the Fed had cited the risks between slower economic growth and faster inflation as equally balanced. Amid the volatility throughout the past year, equity markets have displayed surprising resilience. Most recently, the credit turmoil dampened corporate merger-and-acquisition (M&A) activity, a key source of strength for equity markets. Still, market fundamentals have held firm, dividend payouts and share buybacks have continued to grow, and valuations remain attractive. These tailwinds generally have prevailed over the headwinds created by the slowing U.S. economy, troubled housing market and, recently, a more difficult corporate earnings backdrop. International markets fared even better than U.S. equities, benefiting from robust M&A activity and generally stronger economies. In fixed income markets, mixed economic signals and the credit woes resulted in a flight to quality. At the height of the uncertainty, investors shunned bonds associated with the housing and credit markets in favor of higher-quality Treasury issues. The yield on 10-year Treasury issues, which touched 5.30% in June (its highest level in five years), fell to 4.48% by period-end, while prices correspondingly rose. The tax-exempt bond market has been challenged by a combination of record-setting supply year-to-date, economic uncertainty and concerns around the credit worthiness of bond insurers. This has brought municipal bond prices to relatively attractive levels and, as such, demand generally has remained firm. As you navigate market volatility, we encourage you to review your investment goals with your financial professional and to make portfolio changes, as needed.

See Notes to Financial Statements. 40 ANNUAL REPORT OCTOBER 31, 2007 Notes to Financial Statements 1. Significant Accounting Policies: BlackRock MuniYield Fund, Inc., BlackRock MuniYield Insured Fund, Inc., BlackRock MuniYield Quality Fund, Inc. and BlackRock MuniYield Quality Fund II, Inc. (the "Funds" or individually as the "Fund"), are registered under the Investment Company Act of 1940, as amended, as non-diversified, closed-end management investment companies. The Funds' financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The Funds determine and make available for publication the net asset value of their Common Stock on a daily basis. The Funds' Common Stock shares are listed on the New York Stock Exchange under the symbol MYD for BlackRock MuniYield Fund, Inc., MYI for BlackRock MuniYield Insured Fund, Inc., MQY for BlackRock MuniYield Quality Fund, Inc. and MQT for BlackRock MuniYield Quality Fund II, Inc. The following is a summary of significant accounting policies followed by the Funds. (a) Valuation of investments -- Municipal bonds are traded primarily in the over-the-counter ("OTC") markets and are valued at the last available bid price in the OTC market or on the basis of values as obtained by a pricing service. Pricing services use valuation matrixes that incorporate both dealer-supplied valuations and valuation models. The procedures of the pricing service and its valuations are reviewed by the officers of each of the Funds under the general direction of the respective Board of Directors. Such valuations and procedures are reviewed periodically by the Boards of Directors of the Funds. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their closing prices as of the close of such exchanges. Effective September 4, 2007, exchange-traded options are valued at the mean between the last bid and ask prices at the close of the options market in which the options trade and previously were valued at the last sales price as of the close of options trading on the applicable exchanges. Options traded in the OTC market are valued at the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued by quoted fair values received daily by the Funds' pricing service. Investments in open-end investment companies are valued at their net asset value each business day. Securities and other assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of each Fund's Board of Directors. (b) Derivative financial instruments -- Each Fund may engage in various portfolio investment strategies both to increase the return of the Fund and to hedge, or protect, its exposure to interest rate movements and movements in the securities markets. Losses may arise due to changes in the value of the contract due to an unfavorable change in the price of the underlying security or if the counterparty does not perform under the contract. The counterparty for certain instruments may pledge cash or securities as collateral. o Financial futures contracts -- Each Fund may purchase or sell financial futures contracts and options on such financial futures contracts. Financial futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Fund deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. o Options -- Each Fund may purchase and write call and put options. When the Fund writes an option, an amount equal to the premium received by the Fund is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Fund enters into a closing transaction), the Fund realizes a gain or loss on the option to the extent of the premiums received or paid (or gain or loss to the extent the cost of the closing transaction exceeds the premium paid or received). Written and purchased options are non-income producing investments. o Forward interest rate swaps -- Each Fund may enter into forward interest rate swaps. In a forward interest rate swap, the Fund and the counterparty agree to make periodic net payments on a specified notional contract amount, commencing on a specified future effective date, unless terminated earlier. When the agreement is closed, the Fund records a realized gain or loss in an amount equal to the value of the agreement. o Swaps -- Each Fund may enter into swap agreements, which are OTC contracts in which the Fund and a counterparty agree to make periodic net payments on a specified notional amount. The net payments can be made for a set period of time or may be triggered by a predetermined credit event. The net periodic payments may be based on a fixed or variable interest rate; the change in market value of a specified security, basket of securities, or index; or the return generated by a security. These periodic payments received or made by the Fund are recorded in the accompanying Statements of Operations as realized gains or losses, respectively. Gains or losses are also realized upon termination of the swap agreements. Swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). Risks include changes in the returns of the underlying ANNUAL REPORT OCTOBER 31, 2007 41 Notes to Financial Statements (continued) instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap agreements. (c) Municipal bonds held in trust -- Certain Funds invest in leveraged residual certificates ("TOB Residuals") issued by tender option bond trusts ("TOBs"). A TOB is established by a third party sponsor forming a special purpose entity, into which a Fund, or an agent on behalf of the Fund, transfers municipal securities. A TOB typically issues two classes of beneficial interests: short-term floating rate certificates, which are sold to third party investors, and residual certificates, which are generally issued to the Fund which made the transfer or to affiliates of the Fund. Each Fund's transfers of the municipal securities to a TOB do not qualify for sale treatment under Statement of Financial Accounting Standards No. 140 ("FAS 140") "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities," therefore the municipal securities deposited into a TOB are presented in the Funds' schedules of investments and the proceeds from the transactions are reported as liability for trust certificates. Similarly, proceeds from residual certificates issued to affiliates, if any, from the transaction are included in the liability for trust certificates. Interest income from the underlying security is recorded by the Funds on an accrual basis. Interest expense incurred on the secured borrowing and other expenses related to remarketing, administration and trustee services to a TOB are reported as expenses of a Fund. The floating rate certificates have interest rates that generally reset weekly and their holders have the option to tender certificates to the TOB for redemption at par at each reset date. The residual interests held by the Funds include the right of the Funds (1) to cause the holders of a proportional share of floating rate certificates to tender their certificates at par, and (2) to transfer a corresponding share of the municipal securities from the TOB to the Funds. At October 31, 2007, the aggregate value of the underlying municipal securities transferred to TOBs and the liability for trust certificates were: -------------------------------------------------------------------------------- Underlying Municipal Liability Range of Bonds for Trust Interest Transferred Certificates Rates to TOBs -------------------------------------------------------------------------------- BlackRock MuniYield Fund, Inc. ............... $ 36,112,500 3.693% -- 3.72% $ 77,237,013 BlackRock MuniYield Insured Fund, Inc. ....... $170,637,500 3.525% -- 3.758% $355,738,664 BlackRock MuniYield Quality Fund, Inc. ....... $ 76,685,000 3.686% -- 3.758% $161,925,912 BlackRock MuniYield Quality Fund II, Inc. .... $ 47,725,000 3.701% -- 3.758% $ 98,871,863 -------------------------------------------------------------------------------- Financial transactions executed through TOBs generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment, but tend to outperform the market for fixed rate bonds when interest rates decline or remain relatively stable. Should short-term interest rates rise, a Fund's investments in TOB Residuals likely will adversely affect a Fund's investment income -- net and distributions to shareholders. Fluctuations in the market value of municipal securities deposited into the TOB may adversely affect the Funds' net asset values per share. While the Funds' investment policies and restrictions expressly permit investments in inverse floating rate securities such as TOB Residuals, they generally do not allow the Funds to borrow money for purposes of making investments. The Funds' management believes that the Funds' restrictions on borrowings do not apply to the secured borrowings deemed to have occurred for accounting purposes. (d) Income taxes -- It is each Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. (e) Security transactions and investment income -- Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Interest income is recognized on the accrual basis. The Funds amortize all premiums and discounts on debt securities. (f) Dividends and distributions -- Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. (g) Offering costs -- Direct expenses relating to the public offering of certain Funds' Preferred Stock were charged to capital at the time of issuance of the shares. Any adjustments to estimates of offering costs were recorded back to capital. (h) Recent accounting pronouncements -- In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109." FIN 48 prescribes the minimum recognition threshold a tax position must meet in connection with accounting for uncertainties in income tax positions taken or expected to be taken by an entity, including mutual funds, before being measured and recognized in the financial statements. Adoption of FIN 48 is required for the last net asset value calculation in the first required financial statement reporting period for fiscal years beginning after December 15, 2006. The impact on each of the Fund's financial statements, if any, is currently being assessed. In September 2006, Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"), was issued and is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. At this time, management is evaluating the implications of FAS 157 and its impact on each of the Fund's financial statements, if any, has not been determined. 42 ANNUAL REPORT OCTOBER 31, 2007 Notes to Financial Statements (continued) In addition, in February 2007, Statement of Financial Accounting Standards No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities" ("FAS 159"), was issued and is effective for fiscal years beginning after November 15, 2007. Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007, provided the entity also elects to apply the provisions of FAS 157. FAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. FAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. At this time, management is evaluating the implications of FAS 159 and its impact on each of the Fund's financial statements, if any, has not been determined. (i) Reclassifications -- U.S. generally accepted accounting principles require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. Accordingly, for BlackRock MuniYield Insured Fund, Inc., during the current year, $5,774,510 has been reclassified between accumulated net realized capital losses and paid-in capital in excess of par as a result of permanent differences attributable to the difference between the book and tax treatment of residual interests in tender option bonds. Accordingly, for BlackRock MuniYield Quality Fund, Inc., during the current year, $4,779 has been reclassified between undistributed net investment income and accumulated net realized capital losses as a result of permanent differences attributable to amortization methods on fixed income securities. These reclassifications have no effect on net assets or net asset values per share. 2. Investment Advisory Agreement and Transactions with Affiliates: Each Fund has entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC Financial Services Group, Inc. are the principal owners of BlackRock, Inc. The Manager is responsible for the management of each of the Fund's portfolios and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of each Fund. For such services, each Fund pays a monthly fee at an annual rate of .50% of the Fund's average daily net assets, including proceeds from the issuance of Preferred Stock. The Manager has agreed to reimburse its management fee by the amount of management fees each Fund pays to the Manager indirectly through its investment in Merrill Lynch Institutional Tax-Exempt Fund. The reimbursements for the year ended October 31, 2007 were as follows: -------------------------------------------------------------------------------- Reimbursement by the Manager -------------------------------------------------------------------------------- BlackRock MuniYield Fund, Inc. ............................. $16,677 BlackRock MuniYield Insured Fund, Inc. ..................... $11,868 BlackRock MuniYield Quality Fund, Inc. ..................... $ 8,835 BlackRock MuniYield Quality Fund II, Inc. .................. $ 6,332 -------------------------------------------------------------------------------- In addition, the Manager has entered into a sub-advisory agreement with BlackRock Investment Management, LLC, an affiliate of the Manager, under which the Manager pays the sub-adviser for services it provides a monthly fee at an annual rate that is a percentage of the management fee paid by each Fund to the Manager. The Funds reimbursed the Manager for certain accounting services. The reimbursements for the year ended October 31, 2007 were as follows: -------------------------------------------------------------------------------- Reimbursement to the Manager -------------------------------------------------------------------------------- BlackRock MuniYield Fund, Inc. ............................. $18,788 BlackRock MuniYield Insured Fund, Inc. ..................... $29,566 BlackRock MuniYield Quality Fund, Inc. ..................... $15,264 BlackRock MuniYield Quality Fund II, Inc. .................. $ 8,596 -------------------------------------------------------------------------------- Certain officers and/or directors of the Funds are officers and/or directors of BlackRock, Inc. or its affiliates. 3.

Stock Transactions: Each Fund is authorized to issue 200,000,000 shares of stock, including Preferred Stock, par value $.10 per share, all of which were initially classified as Common Stock. Each Board of Directors is authorized, however, to reclassify any unissued shares of stock without approval of the holders of Common Stock. Common Stock BlackRock MuniYield Fund, Inc. Shares issued and outstanding during the years ended October 31, 2007 and October 31, 2006 increased by 236,501 and 346,987, respectively, as a result of dividend reinvestment.

Restatement Information: Subsequent to the initial issuance of BlackRock MuniYield Insured Fund, Inc.'s October 31, 2006 financial statements, the Fund determined that the criteria for sale accounting in FAS 140 had not been met for certain transfers of municipal bonds and that these transfers should have been accounted for as secured borrowings rather than as sales. As a result, certain financial highlights for each of the three years in the period ended October 31, 2005 have been restated to give effect to recording the transfers of the municipal bonds as secured borrowings, including recording interest on the bonds as interest income and interest on the secured borrowings as interest expense. ------------------------------------------------------------------------------------------------------------------------------------ Financial Highlights for BlackRock MuniYield Insured Fund, Inc.

ANNUAL REPORT OCTOBER 31, 2007 45 Report of Independent Registered Public Accounting Firm To the Shareholders and Boards of Directors of BlackRock MuniYield Fund, Inc., BlackRock MuniYield Insured Fund, Inc., BlackRock MuniYield Quality Fund, Inc. and BlackRock MuniYield Quality Fund II, Inc.: We have audited each of the accompanying statements of net assets, including the schedules of investments, of BlackRock MuniYield Fund, Inc., BlackRock MuniYield Quality Fund, Inc., and BlackRock MuniYield Quality Fund II, Inc. as of October 31, 2007, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended for each of the respective funds. We have also audited the accompanying statement of net assets, including the schedule of investments, of BlackRock MuniYield Insured Fund, Inc. as of October 31, 2007, and the related statement of operations for the year then ended, and the statements of changes in net assets and the financial highlights for each of the two years in the period then ended. The above-referenced funds are hereinafter referred to collectively as the "Funds." These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on the financial statements and financial highlights of each of the Funds based on our audits. The financial highlights of BlackRock MuniYield Insured Fund, Inc. for each of the three years in the period ended October 31, 2005 (before the restatement described in Note 6) were audited by other auditors whose report, dated December 9, 2005, expressed a qualified opinion on those financial highlights because of the errors described in Note 6. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Funds are not required to have, nor were we engaged to perform, audits of their internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Funds' internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2007, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights of BlackRock MuniYield Fund, Inc., BlackRock MuniYield Quality Fund, Inc. and BlackRock MuniYield Quality Fund II, Inc. referred to above present fairly, in all material respects, the respective financial positions of each of those funds as of October 31, 2007, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and their financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. Additionally, in our opinion, the financial statements and financial highlights of BlackRock MuniYield Insured Fund, Inc. as of October 31, 2007 and for each of the two years in the period then ended, present fairly, in all material respects, its financial position as of October 31, 2007, the results of its operations for the year then ended, and the changes in its net assets and the financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. We also have audited the adjustments, applied by management, to restate certain financial highlights of BlackRock MuniYield Insured Fund, Inc. (the "Insured Fund") for each of the three years in the period ended October 31, 2005, to correct the errors described in Note 6. These adjustments are the responsibility of the Insured Fund's management. The audit procedures that we performed with respect to the adjustments included such tests as we considered necessary in the circumstances and were designed to obtain reasonable assurance about whether the adjustments are appropriate and have been properly applied, in all material respects, to the restated information in Insured Fund's financial highlights for each of the three years in the period ended October 31, 2005. We did not perform any audit procedures designed to assess whether any additional adjustments or disclosures to the Insured Fund's financial highlights for each of the three years in the period ended October 31, 2005 might be necessary in order for such financial highlights to be presented in conformity with accounting principles generally accepted in the United States of America. In our opinion, the adjustments to the financial highlights of the Insured Fund for each of the three years in the period ended October 31, 2005, for the restatement described in Note 6 are appropriate and have been properly applied, in all material respects. However, we were not engaged to audit, review, or apply any procedures to the Insured Fund's financial highlights for each of the three years in the period ended October 31, 2005, other than with respect to the adjustments described in Note 6 and, accordingly, we do not express an opinion or any other form of assurance on the Insured Fund's financial highlights for each of the three years in the period ended October 31, 2005. Deloitte & Touche LLP Princeton, New Jersey December 26, 2007 46 ANNUAL REPORT OCTOBER 31, 2007 Important Tax Information All of the net investment income distributions paid by BlackRock MuniYield Fund, Inc., BlackRock MuniYield Insured Fund, Inc., BlackRock MuniYield Quality Fund, Inc. and BlackRock MuniYield Quality Fund II, Inc. during the taxable year ended October 31, 2007 qualify as tax-exempt interest dividends for federal income tax purposes. ANNUAL REPORT OCTOBER 31, 2007 47 The Benefits and Risks of Leveraging The Funds utilize leverage to seek to enhance the yield and net asset value of their Common Stock. However, these objectives cannot be achieved in all interest rate environments. To leverage, each Fund issues Preferred Stock, which pays dividends at prevailing short-term interest rates, and invests the proceeds in long-term municipal bonds. The interest earned on these investments, net of dividends to Preferred Stock, is paid to Common Stock shareholders in the form of dividends, and the value of these portfolio holdings is reflected in the per share net asset value of each Fund's Common Stock. However, in order to benefit Common Stock shareholders, the yield curve must be positively sloped; that is, short-term interest rates must be lower than long-term interest rates. At the same time, a period of generally declining interest rates will benefit Common Stock shareholders. If either of these conditions change, then the risks of leveraging will begin to outweigh the benefits. To illustrate these concepts, assume a fund's Common Stock capitalization of $100 million and the issuance of Preferred Stock for an additional $50 million, creating a total value of $150 million available for investment in long-term municipal bonds. If prevailing short-term interest rates are approximately 3% and long-term interest rates are approximately 6%, the yield curve has a strongly positive slope. The fund pays dividends on the $50 million of Preferred Stock based on the lower short-term interest rates. At the same time, the fund's total portfolio of $150 million earns the income based on long-term interest rates. In this case, the dividends paid to Preferred Stock shareholders are significantly lower than the income earned on the fund's long-term investments, and therefore the Common Stock shareholders are the beneficiaries of the incremental yield. However, if short-term interest rates rise, narrowing the differential between short-term and long-term interest rates, the incremental yield pickup on the Common Stock will be reduced or eliminated completely. At the same time, the market value of the fund's Common Stock (that is, its price as listed on the New York Stock Exchange) may, as a result, decline. Furthermore, if long-term interest rates rise, the Common Stock's net asset value will reflect the full decline in the price of the portfolio's investments, since the value of the fund's Preferred Stock does not fluctuate. In addition to the decline in net asset value, the market value of the fund's Common Stock may also decline. As of October 31, 2007, BlackRock MuniYield Fund, Inc., BlackRock MuniYield Insured Fund, Inc., BlackRock MuniYield Quality Fund, Inc. and BlackRock MuniYield Quality Fund II, Inc. had leverage amounts, due to Auction Market Preferred Stock, of 34.58%, 36.71%, 35.52% and 35.14% of total net assets, respectively, before the deduction of Preferred Stock. As a part of their investment strategy, the Funds may invest in certain securities whose potential income return is inversely related to changes in a floating interest rate ("inverse floaters"). In general, income on inverse floaters will decrease when short-term interest rates increase and increase when short-term interest rates decrease. Investments in inverse floaters may be characterized as derivative securities and may subject the Funds to the risks of reduced or eliminated interest payments and losses of invested principal. In addition, inverse floaters have the effect of providing investment leverage and, as a result, the market value of such securities will generally be more volatile than that of fixed rate, tax-exempt securities. To the extent the Funds invest in inverse floaters, the market value of each Fund's portfolio and the net asset value of each Fund's shares may also be more volatile than if the Funds did not invest in these securities. To the extent the Funds invest in inverse floaters, the market value of the Funds' portfolio and net asset value of the Funds' shares may also be more volatile than if the Funds did not invest in these securities. (See Note 1(c) to Financial Statements for details of municipal bonds held in trust.) Swap Agreements The Funds may invest in swap agreements, which are over-the-counter contracts in which one party agrees to make periodic payments based on the change in market value of a specified bond, basket of bonds, or index in return for periodic payments based on a fixed or variable interest rate or the change in market value of a different bond, basket of bonds or index. Swap agreements may be used to obtain exposure to a bond or market without owning or taking physical custody of securities. Swap agreements involve the risk that the party with whom each Fund has entered into a swap will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to pay the other party to the agreement. 48 ANNUAL REPORT OCTOBER 31, 2007 Automatic Dividend Reinvestment Plan How the Plan Works -- The Funds offer a Dividend Reinvestment Plan (the "Plan") under which income and capital gains dividends paid by each Fund are automatically reinvested in additional shares of Common Stock of each Fund. The Plan is administered on behalf of the shareholders by The Bank of New York Mellon for BlackRock MuniYield Fund, Inc. and BlackRock MuniYield Quality Fund II, Inc. and Computershare Trust Company, N.A. for BlackRock MuniYield Insured Fund, Inc. and BlackRock MuniYield Quality Fund, Inc. (individually, the "Plan Agent" or together, the "Plan Agents"). Under the Plan, whenever the Funds declare a dividend, participants in the Plan will receive the equivalent in shares of Common Stock of each Fund. The Plan Agents will acquire the shares for the participant's account either (i) through receipt of additional unissued but authorized shares of each Fund ("newly issued shares") or (ii) by purchase of outstanding shares of Common Stock on the open market on the New York Stock Exchange or elsewhere. If, on the dividend payment date, each Fund's net asset value per share is equal to or less than the market price per share plus estimated brokerage commissions (a condition often referred to as a "market premium"), the Plan Agents will invest the dividend amount in newly issued shares. If the Funds' net asset value per share is greater than the market price per share (a condition often referred to as a "market discount"), the Plan Agents will invest the dividend amount by purchasing on the open market additional shares. If the Plan Agents are unable to invest the full dividend amount in open market purchases, or if the market discount shifts to a market premium during the purchase period, the Plan Agents will invest any uninvested portion in newly issued shares. The shares acquired are credited to each shareholder's account. The amount credited is determined by dividing the dollar amount of the dividend by either (i) when the shares are newly issued, the net asset value per share on the date the shares are issued or (ii) when shares are purchased in the open market, the average purchase price per share. Participation in the Plan -- Participation in the Plan is automatic, that is, a shareholder is automatically enrolled in the Plan when he or she purchases shares of Common Stock of the Funds unless the shareholder specifically elects not to participate in the Plan. Shareholders who elect not to participate will receive all dividend distributions in cash. Shareholders who do not wish to participate in the Plan, must advise their Plan Agent in writing (at the address set forth below) that they elect not to participate in the Plan. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by writing to the Plan Agent. Benefits of the Plan -- The Plan provides an easy, convenient way for shareholders to make additional, regular investments in the Funds. The Plan promotes a long-term strategy of investing at a lower cost. All shares acquired pursuant to the Plan receive voting rights. In addition, if the market price plus commissions of each Fund's shares is above the net asset value, participants in the Plan will receive shares of the Funds for less than they could otherwise purchase them and with a cash value greater than the value of any cash distribution they would have received. However, there may not be enough shares available in the market to make distributions in shares at prices below the net asset value. Also, since each Fund does not redeem shares, the price on resale may be more or less than the net asset value. Plan Fees -- There are no enrollment fees or brokerage fees for participating in the Plan. The Plan Agents' service fees for handling the reinvestment of distributions are paid for by the Funds. However, brokerage commissions may be incurred when the Funds purchase shares on the open market and shareholders will pay a pro rata share of any such commissions. Tax Implications -- The automatic reinvestment of dividends and distributions will not relieve participants of any federal, state or local income tax that may be payable (or required to be withheld) on such dividends. Therefore, income and capital gains may still be realized even though shareholders do not receive cash. The value of shares acquired pursuant to the Plan will generally be excluded from gross income to the extent that the cash amount reinvested would be excluded from gross income. If, when the Funds' shares are trading at a market premium, the Funds issue shares pursuant to the Plan that have a greater fair market value than the amount of cash reinvested, it is possible that all or a portion of the discount from the market value (which may not exceed 5% of the fair market value of each Fund's shares) could be viewed as a taxable distribution. If the discount is viewed as a taxable distribution, it is also possible that the taxable character of this discount would be allocable to all the shareholders, including shareholders who do not participate in the Plan. Thus, shareholders who do not participate in the Plan might be required to report as ordinary income a portion of their distributions equal to their allocable share of the discount.

Item 3 - Audit Committee Financial Expert - The registrant's board of directors or trustees, as applicable (the "board of directors") has determined that (i) the registrant has the following audit committee financial experts serving on its audit committee and (ii) each audit committee financial expert is independent: Joe Grills (term ended effective November 1, 2007) Robert S. Salomon, Jr. Kent Dixon (term began effective November 1, 2007) Frank J. Fabozzi (term began effective November 1, 2007) W. Carl Kester (term began effective November 1, 2007) James T. Flynn (term began effective November 1, 2007) Karen P. Robards (term began effective November 1, 2007) The registrant's board of directors has determined that W. Carl Kester and Karen P. Robards qualify as financial experts pursuant to Item 3(c)(4) of Form N-CSR. Prof. Kester has a thorough understanding of generally accepted accounting principles, financial statements and internal control over financial reporting as well as audit committee functions. Prof. Kester has been involved in providing valuation and other financial consulting services to corporate clients since 1978. Prof. Kester's financial consulting services present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the registrant's financial statements. Ms. Robards has a thorough understanding of generally accepted accounting principles, financial statements and internal control over financial reporting as well as audit committee functions. Ms. Robards has been President of Robards & Company, a financial advisory firm, since 1987. Ms. Robards was formerly an investment banker for more than 10 years where she was responsible for evaluating and assessing the performance of companies based on their financial results. Ms. Robards has over 30 years of experience analyzing financial statements. She also is the member of the Audit Committees of one publicly held company and a non-profit organization. Under applicable securities laws, a person determined to be an audit committee financial expert will not be deemed an "expert" for any purpose, including without limitation for the purposes of Section 11 of the Securities Act of 1933, as a result of being designated or identified as an audit committee financial expert. The designation or identification as an audit committee financial expert does not impose on such person any duties, obligations, or liabilities greater than the duties, obligations, and liabilities imposed on such person as a member of the audit committee and board of directors in the absence of such designation or identification.

(e)(1) Audit Committee Pre-Approval Policies and Procedures: The registrant's audit committee (the "Committee") has adopted policies and procedures with regard to the pre-approval of services. Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the registrant's affiliated service providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are a) consistent with the SEC's auditor independence rules and b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis ("general pre-approval"). However, such services will only be deemed pre-approved provided that any individual project does not exceed $5,000 attributable to the registrant or $50,000 for all of the registrants the Committee oversees. Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting. (e)(2) None of the services described in each of Items 4(b) through (d) were approved by the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

Corporate Meetings..................................................... Investment Companies................................................... Environmental and Social Issues........................................ Notice to Clients............................................................ Proxy Voting Policies and Procedures These Proxy Voting Policies and Procedures ("Policy") for BlackRock Advisors, LLC and its affiliated U.S. registered investment advisers(1) ("BlackRock") reflect our duty as a fiduciary under the Investment Advisers Act of 1940 (the "Advisers Act") to vote proxies in the best interests of our clients. BlackRock serves as the investment manager for investment companies, other commingled investment vehicles and/or separate accounts of institutional and other clients. The right to vote proxies for securities held in such accounts belongs to BlackRock's clients. Certain clients of BlackRock have retained the right to vote such proxies in general or in specific circumstances.(2) Other clients, however, have delegated to BlackRock the right to vote proxies for securities held in their accounts as part of BlackRock's authority to manage, acquire and dispose of account assets. When BlackRock votes proxies for a client that has delegated to BlackRock proxy voting authority, BlackRock acts as the client's agent. Under the Advisers Act, an investment adviser is a fiduciary that owes each of its clients a duty of care and loyalty with respect to all services the adviser undertakes on the client's behalf, including proxy voting. BlackRock is therefore subject to a fiduciary duty to vote proxies in a manner BlackRock believes is consistent with the client's best interests,(3) whether or not the client's proxy voting is subject to the fiduciary standards of the Employee Retirement Income Security Act of 1974 ("ERISA").(4) When voting proxies for client accounts (including investment companies), BlackRock's primary objective is to make voting decisions solely in the best interests of clients and ERISA clients' plan beneficiaries and participants. In fulfilling its obligations to clients, BlackRock will seek to act in a manner that it believes is most likely to enhance the economic value of the underlying securities held in client accounts.(5) It is imperative that BlackRock considers the interests of its clients, and not the interests of BlackRock, when voting proxies and that real (or perceived) material conflicts that may arise between BlackRock's interest and those of BlackRock's clients are properly addressed and resolved. ---------- (1) The Policy does not apply to BlackRock Asset Management U.K. Limited and BlackRock Investment Managers International Limited, which are U.S. registered investment advisers based in the United Kingdom. (2) In certain situations, a client may direct BlackRock to vote in accordance with the client's proxy voting policies. In these situations, BlackRock will seek to comply with such policies to the extent it would not be inconsistent with other BlackRock legal responsibilities. (3) Letter from Harvey L. Pitt, Chairman, SEC, to John P.M. Higgins, President, Ram Trust Services (February 12, 2002) (Section 206 of the Investment Advisers Act imposes a fiduciary responsibility to vote proxies fairly and in the best interests of clients); SEC Release No. IA-2106 (February 3, 2003). (4) DOL Interpretative Bulletin of Sections 402, 403 and 404 of ERISA at 29 C.F.R. 2509.94-2. (5) Other considerations, such as social, labor, environmental or other policies, may be of interest to particular clients. While BlackRock is cognizant of the importance of such considerations, when voting proxies it will generally take such matters into account only to the extent that they have a direct bearing on the economic value of the underlying securities. To the extent that a BlackRock client desires to pursue a particular social, labor, environmental or other agenda through the proxy votes made for its securities held through BlackRock as investment adviser, BlackRock encourages the client to consider retaining direct proxy voting authority or to appoint independently a special proxy voting fiduciary other than BlackRock. 1 Advisers Act Rule 206(4)-6 was adopted by the SEC in 2003 and requires, among other things, that an investment adviser that exercises voting authority over clients' proxy voting adopt policies and procedures reasonably designed to ensure that the adviser votes proxies in the best interests of clients, discloses to its clients information about those policies and procedures and also discloses to clients how they may obtain information on how the adviser has voted their proxies. In light of such fiduciary duties, the requirements of Rule 206(4)-6, and given the complexity of the issues that may be raised in connection with proxy votes, BlackRock has adopted these policies and procedures. BlackRock's Equity Investment Policy Oversight Committee, or a sub-committee thereof (the "Committee"), addresses proxy voting issues on behalf of BlackRock and its clients.(6) The Committee is comprised of senior members of BlackRock's Portfolio Management Group and advised by BlackRock's Legal and Compliance Department. ---------- (6) Subject to the Proxy Voting Policies of Merrill Lynch Bank & Trust Company FSB, the Committee may also function jointly as the Proxy Voting Committee for Merrill Lynch Bank & Trust Company FSB trust accounts managed by personnel dually-employed by BlackRock. 2 I. Scope of Committee Responsibilities The Committee shall have the responsibility for determining how to address proxy votes made on behalf of all BlackRock clients, except for clients who have retained the right to vote their own proxies, either generally or on any specific matter. In so doing, the Committee shall seek to ensure that proxy votes are made in the best interests of clients, and that proxy votes are determined in a manner free from unwarranted or inappropriate influences. The Committee shall also oversee the overall administration of proxy voting for BlackRock accounts.(7) The Committee shall establish BlackRock's proxy voting guidelines, with such advice, participation and research as the Committee deems appropriate from portfolio managers, proxy voting services or other knowledgeable interested parties. As it is anticipated that there will not necessarily be a "right" way to vote proxies on any given issue applicable to all facts and circumstances, the Committee shall also be responsible for determining how the proxy voting guidelines will be applied to specific proxy votes, in light of each issuer's unique structure, management, strategic options and, in certain circumstances, probable economic and other anticipated consequences of alternative actions. In so doing, the Committee may determine to vote a particular proxy in a manner contrary to its generally stated guidelines. The Committee may determine that the subject matter of certain proxy issues are not suitable for general voting guidelines and requires a case-by-case determination, in which case the Committee may elect not to adopt a specific voting guideline applicable to such issues. BlackRock believes that certain proxy voting issues - such as approval of mergers and other significant corporate transactions - require investment analysis akin to investment decisions, and are therefore not suitable for general guidelines. The Committee may elect to adopt a common BlackRock position on certain proxy votes that are akin to investment decisions, or determine to permit portfolio managers to make individual decisions on how best to maximize economic value for the accounts for which they are responsible (similar to normal buy/sell investment decisions made by such portfolio managers).(8) While it is expected that BlackRock, as a fiduciary, will generally seek to vote proxies over which BlackRock exercises voting authority in a uniform manner for all BlackRock clients, the Committee, in conjunction with the portfolio manager of an account, may determine that the specific circumstances of such account require that such account's proxies be voted differently due to such account's investment objective or other factors that differentiate it from other accounts. In addition, on proxy votes that are akin to investment decisions, BlackRock believes portfolio managers may from time to time ---------- (7) The Committee may delegate day-to-day administrative responsibilities to other BlackRock personnel and/or outside service providers, as appropriate. (8) The Committee will normally defer to portfolio managers on proxy votes that are akin to investment decisions except for proxy votes that involve a material conflict of interest, in which case it will determine, in its discretion, the appropriate voting process so as to address such conflict. 3 legitimately reach differing but equally valid views, as fiduciaries for BlackRock's clients, on how best to maximize economic value in respect of a particular investment. The Committee will also be responsible for ensuring the maintenance of records of each proxy vote, as required by Advisers Act Rule 204-2.(9) All records will be maintained in accordance with applicable law. Except as may be required by applicable legal requirements, or as otherwise set forth herein, the Committee's determinations and records shall be treated as proprietary, nonpublic and confidential. The Committee shall be assisted by other BlackRock personnel, as may be appropriate. In particular, the Committee has delegated to the BlackRock Operations Department responsibility for monitoring corporate actions and ensuring that proxy votes are submitted in a timely fashion. The Operations Department shall ensure that proxy voting issues are promptly brought to the Committee's attention and that the Committee's proxy voting decisions are appropriately disseminated and implemented. To assist BlackRock in voting proxies, the Committee may retain the services of a firm providing such services. BlackRock has currently retained Institutional Shareholder Services ("ISS") in that role. ISS is an independent adviser that specializes in providing a variety of fiduciary-level proxy-related services to institutional investment managers, plan sponsors, custodians, consultants, and other institutional investors. The services provided to BlackRock may include, but are not limited to, in-depth research, voting recommendations (which the Committee is not obligated to follow), vote execution, and recordkeeping. ---------- (9) The Committee may delegate the actual maintenance of such records to an outside service provider. Currently, the Committee has delegated the maintenance of such records to Institutional Shareholder Services. 4 II. Special Circumstances Routine Consents. BlackRock may be asked from time to time to consent to an amendment to, or grant a waiver under, a loan agreement, partnership agreement, indenture or other governing document of a specific financial instrument held by BlackRock clients. BlackRock will generally treat such requests for consents not as "proxies" subject to these Proxy Voting Policies and Procedures but as investment matters to be dealt with by the responsible BlackRock investment professionals would, provided that such consents (i) do not relate to the election of a board of directors or appointment of auditors of a public company, and (ii) either (A) would not otherwise materially affect the structure, management or control of a public company, or (B) relate to a company in which BlackRock clients hold only interests in bank loans or debt securities and are consistent with customary standards and practices for such instruments. Securities on Loan. Registered investment companies that are advised by BlackRock as well as certain of our advisory clients may participate in securities lending programs. Under most securities lending arrangements, securities on loan may not be voted by the lender (unless the loan is recalled). BlackRock believes that each client has the right to determine whether participating in a securities lending program enhances returns, to contract with the securities lending agent of its choice and to structure a securities lending program, through its lending agent, that balances any tension between loaning and voting securities in a matter that satisfies such client. If client has decided to participate in a securities lending program, BlackRock will therefore defer to the client's determination and not attempt to seek recalls solely for the purpose of voting routine proxies as this could impact the returns received from securities lending and make the client a less desirable lender in a marketplace. Where a client retains a lending agent that is unaffiliated with BlackRock, BlackRock will generally not seek to vote proxies relating to securities on loan because BlackRock does not have a contractual right to recall such loaned securities for the purpose of voting proxies. Where BlackRock or an affiliate acts as the lending agent, BlackRock will also generally not seek to recall loaned securities for proxy voting purposes, unless the portfolio manager responsible for the account or the Committee determines that voting the proxy is in the client's best interest and requests that the security be recalled. Voting Proxies for Non-US Companies. While the proxy voting process is well established in the United States, voting proxies of non-US companies frequently involves logistical issues which can affect BlackRock's ability to vote such proxies, as well as the desirability of voting such proxies. These issues include (but are not limited to): (i) untimely notice of shareholder meetings, (ii) restrictions on a foreigner's ability to exercise votes, (iii) requirements to vote proxies in person, (iv) "shareblocking" (requirements that investors who exercise their voting rights surrender the right to dispose of their holdings for some specified period in proximity to the shareholder meeting), (v) potential difficulties in translating the proxy, and (vi) requirements to provide local agents with unrestricted powers of attorney to facilitate voting instructions. 5 As a consequence, BlackRock votes proxies of non-US companies only on a "best-efforts" basis. In addition, the Committee may determine that it is generally in the best interests of BlackRock clients not to vote proxies of companies in certain countries if the Committee determines that the costs (including but not limited to opportunity costs associated with shareblocking constraints) associated with exercising a vote generally are expected to outweigh the benefit the client will derive by voting on the issuer's proposal. If the Committee so determines in the case of a particular country, the Committee (upon advice from BlackRock portfolio managers) may override such determination with respect to a particular issuer's shareholder meeting if the Committee believes the benefits of seeking to exercise a vote at such meeting outweighs the costs, in which case BlackRock will seek to vote on a best-efforts basis. Securities Sold After Record Date. With respect to votes in connection with securities held on a particular record date but sold from a client account prior to the holding of the related meeting, BlackRock may take no action on proposals to be voted on in such meeting. Conflicts of Interest. From time to time, BlackRock may be required to vote proxies in respect of an issuer that is an affiliate of BlackRock (a "BlackRock Affiliate"), or a money management or other client of BlackRock (a "BlackRock Client").(10) In such event, provided that the Committee is aware of the real or potential conflict, the following procedures apply: o The Committee intends to adhere to the voting guidelines set forth herein for all proxy issues including matters involving BlackRock Affiliates and BlackRock Clients. The Committee may, in its discretion for the purposes of ensuring that an independent determination is reached, retain an independent fiduciary to advise the Committee on how to vote or to cast votes on behalf of BlackRock's clients; and o if the Committee determines not to retain an independent fiduciary, or does not desire to follow the advice of such independent fiduciary, the Committee shall determine how to vote the proxy after consulting with the BlackRock Legal and Compliance Department and concluding that the vote cast is in the client's best interest notwithstanding the conflict. ---------- (10) Such issuers may include investment companies for which BlackRock provides investment advisory, administrative and/or other services. 6 III. Voting Guidelines The Committee has determined that it is appropriate and in the best interests of BlackRock's clients to adopt the following voting guidelines, which represent the Committee's usual voting position on certain recurring proxy issues that are not expected to involve unusual circumstances. With respect to any particular proxy issue, however, the Committee may elect to vote differently than a voting guideline if the Committee determines that doing so is, in the Committee's judgment, in the best interest of its clients. The guidelines may be reviewed at any time upon the request of any Committee member and may be amended or deleted upon the vote of a majority of voting Committee members present at a Committee meeting for which there is a quorum. 7 A. Boards of Directors These proposals concern those issues submitted to shareholders relating to the composition of the Board of Directors of companies other than investment companies. As a general matter, the Committee believes that a company's Board of Directors (rather than shareholders) is most likely to have access to important, nonpublic information regarding a company's business and prospects, and is therefore best-positioned to set corporate policy and oversee management. The Committee therefore believes that the foundation of good corporate governance is the election of qualified, independent corporate directors who are likely to diligently represent the interests of shareholders and oversee management of the corporation in a manner that will seek to maximize shareholder value over time. In individual cases, the Committee may look at a Director nominee's history of representing shareholder interests as a director of other companies, or other factors to the extent the Committee deems relevant. The Committee's general policy is to vote: -------------------------------------------------------------------------------- # VOTE and DESCRIPTION -------------------------------------------------------------------------------- A.1 FOR nominees for director of United States companies in uncontested elections, except for nominees who o have missed at least two meetings and, as a result, attended less than 75% of meetings of the Board of Directors and its committees the previous year, unless the nominee missed the meeting(s) due to illness or company business o voted to implement or renew a "dead-hand" poison pill o ignored a shareholder proposal that was approved by either a majority of the shares outstanding in any year or by the majority of votes cast for two consecutive years o failed to act on takeover offers where the majority of the shareholders have tendered their shares o are corporate insiders who serve on the audit, compensation or nominating committees or on a full Board that does not have such committees composed exclusively of independent directors o on a case-by-case basis, have served as directors of other companies with allegedly poor corporate governance o sit on more than six boards of public companies -------------------------------------------------------------------------------- A.2 FOR nominees for directors of non-U.S. companies in uncontested elections, except for nominees from whom the Committee determines to withhold votes due to the nominees' poor records of representing shareholder interests, on a case-by-case basis -------------------------------------------------------------------------------- A.3 FOR proposals to declassify Boards of Directors, except where there exists a legitimate purpose for classifying boards -------------------------------------------------------------------------------- A.4 AGAINST proposals to classify Boards of Directors, except where there exists a legitimate purpose for classifying boards -------------------------------------------------------------------------------- 8 -------------------------------------------------------------------------------- A.5 AGAINST proposals supporting cumulative voting -------------------------------------------------------------------------------- A.6 FOR proposals eliminating cumulative voting -------------------------------------------------------------------------------- A.7 FOR proposals supporting confidential voting -------------------------------------------------------------------------------- A.8 FOR proposals seeking election of supervisory board members -------------------------------------------------------------------------------- A.9 AGAINST shareholder proposals seeking additional representation of women and/or minorities generally (i.e., not specific individuals) to a Board of Directors -------------------------------------------------------------------------------- A.10 AGAINST shareholder proposals for term limits for directors -------------------------------------------------------------------------------- A.11 FOR shareholder proposals to establish a mandatory retirement age for directors who attain the age of 72 or older -------------------------------------------------------------------------------- A.12 AGAINST shareholder proposals requiring directors to own a minimum amount of company stock -------------------------------------------------------------------------------- A.13 FOR proposals requiring a majority of independent directors on a Board of Directors -------------------------------------------------------------------------------- A.14 FOR proposals to allow a Board of Directors to delegate powers to a committee or committees -------------------------------------------------------------------------------- A.15 FOR proposals to require audit, compensation and/or nominating committees of a Board of Directors to consist exclusively of independent directors -------------------------------------------------------------------------------- A.16 AGAINST shareholder proposals seeking to prohibit a single person from occupying the roles of chairman and chief executive officer -------------------------------------------------------------------------------- A.17 FOR proposals to elect account inspectors -------------------------------------------------------------------------------- A.18 FOR proposals to fix the membership of a Board of Directors at a specified size -------------------------------------------------------------------------------- A.19 FOR proposals permitting shareholder ability to nominate directors directly -------------------------------------------------------------------------------- A.20 AGAINST proposals to eliminate shareholder ability to nominate directors directly -------------------------------------------------------------------------------- A.21 FOR proposals permitting shareholder ability to remove directors directly -------------------------------------------------------------------------------- A.22 AGAINST proposals to eliminate shareholder ability to remove directors directly -------------------------------------------------------------------------------- 9 B. Auditors These proposals concern those issues submitted to shareholders related to the selection of auditors. As a general matter, the Committee believes that corporate auditors have a responsibility to represent the interests of shareholders and provide an independent view on the propriety of financial reporting decisions of corporate management. While the Committee will generally defer to a corporation's choice of auditor, in individual cases, the Committee may look at an auditors' history of representing shareholder interests as auditor of other companies, to the extent the Committee deems relevant. The Committee's general policy is to vote: -------------------------------------------------------------------------------- B.1 FOR approval of independent auditors, except for o auditors that have a financial interest in, or material association with, the company they are auditing, and are therefore believed by the Committee not to be independent o auditors who have rendered an opinion to any company which in the Committee's opinion is either not consistent with best accounting practices or not indicative of the company's financial situation o on a case-by-case basis, auditors who in the Committee's opinion provide a significant amount of non-audit services to the company -------------------------------------------------------------------------------- B.2 FOR proposals seeking authorization to fix the remuneration of auditors -------------------------------------------------------------------------------- B.3 FOR approving internal statutory auditors -------------------------------------------------------------------------------- B.4 FOR proposals for audit firm rotation, except for proposals that would require rotation after a period of less than 5 years -------------------------------------------------------------------------------- 10 C. Compensation and Benefits These proposals concern those issues submitted to shareholders related to management compensation and employee benefits. As a general matter, the Committee favors disclosure of a company's compensation and benefit policies and opposes excessive compensation, but believes that compensation matters are normally best determined by a corporation's board of directors, rather than shareholders. Proposals to "micro-manage" a company's compensation practices or to set arbitrary restrictions on compensation or benefits will therefore generally not be supported. The Committee's general policy is to vote: -------------------------------------------------------------------------------- C.1 IN ACCORDANCE WITH THE RECOMMENDATION OF ISS on compensation plans if the ISS recommendation is based solely on whether or not the company's plan satisfies the allowable cap as calculated by ISS. If the recommendation of ISS is based on factors other than whether the plan satisfies the allowable cap the Committee will analyze the particular proposed plan. This policy applies to amendments of plans as well as to initial approvals. -------------------------------------------------------------------------------- C.2 FOR proposals to eliminate retirement benefits for outside directors -------------------------------------------------------------------------------- C.3 AGAINST proposals to establish retirement benefits for outside directors -------------------------------------------------------------------------------- C.4 FOR proposals approving the remuneration of directors or of supervisory board members -------------------------------------------------------------------------------- C.5 AGAINST proposals to reprice stock options -------------------------------------------------------------------------------- C.6 FOR proposals to approve employee stock purchase plans that apply to all employees. This policy applies to proposals to amend ESPPs if the plan as amended applies to all employees. -------------------------------------------------------------------------------- C.7 FOR proposals to pay retirement bonuses to directors of Japanese companies unless the directors have served less than three years -------------------------------------------------------------------------------- C.8 AGAINST proposals seeking to pay outside directors only in stock -------------------------------------------------------------------------------- C.9 FOR proposals seeking further disclosure of executive pay or requiring companies to report on their supplemental executive retirement benefits -------------------------------------------------------------------------------- C.10 AGAINST proposals to ban all future stock or stock option grants to executives -------------------------------------------------------------------------------- C.11 AGAINST option plans or grants that apply to directors or employees of "related companies" without adequate disclosure of the corporate relationship and justification of the option policy -------------------------------------------------------------------------------- C.12 FOR proposals to exclude pension plan income in the calculation of earnings used in determining executive bonuses/compensation -------------------------------------------------------------------------------- 11 D. Capital Structure These proposals relate to various requests, principally from management, for approval of amendments that would alter the capital structure of a company, such as an increase in authorized shares. As a general matter, the Committee will support requests that it believes enhance the rights of common shareholders and oppose requests that appear to be unreasonably dilutive. The Committee's general policy is to vote: -------------------------------------------------------------------------------- D.1 AGAINST proposals seeking authorization to issue shares without preemptive rights except for issuances up to 10% of a non-US company's total outstanding capital -------------------------------------------------------------------------------- D.2 FOR management proposals seeking preemptive rights or seeking authorization to issue shares with preemptive rights -------------------------------------------------------------------------------- D.3 FOR management proposals approving share repurchase programs -------------------------------------------------------------------------------- D.4 FOR management proposals to split a company's stock -------------------------------------------------------------------------------- D.5 FOR management proposals to denominate or authorize denomination of securities or other obligations or assets in Euros -------------------------------------------------------------------------------- D.6 FOR proposals requiring a company to expense stock options (unless the company has already publicly committed to do so by a certain date). -------------------------------------------------------------------------------- 12 E. Corporate Charter and By-Laws These proposals relate to various requests for approval of amendments to a corporation's charter or by-laws, principally for the purpose of adopting or redeeming "poison pills". As a general matter, the Committee opposes poison pill provisions. The Committee's general policy is to vote: -------------------------------------------------------------------------------- E.1 AGAINST proposals seeking to adopt a poison pill -------------------------------------------------------------------------------- E.2 FOR proposals seeking to redeem a poison pill -------------------------------------------------------------------------------- E.3 FOR proposals seeking to have poison pills submitted to shareholders for ratification -------------------------------------------------------------------------------- E.4 FOR management proposals to change the company's name -------------------------------------------------------------------------------- 13 F. Corporate Meetings These are routine proposals relating to various requests regarding the formalities of corporate meetings. The Committee's general policy is to vote: -------------------------------------------------------------------------------- F.1 AGAINST proposals that seek authority to act on "any other business that may arise" -------------------------------------------------------------------------------- F.2 FOR proposals designating two shareholders to keep minutes of the meeting -------------------------------------------------------------------------------- F.3 FOR proposals concerning accepting or approving financial statements and statutory reports -------------------------------------------------------------------------------- F.4 FOR proposals approving the discharge of management and the supervisory board -------------------------------------------------------------------------------- F.5 FOR proposals approving the allocation of income and the dividend -------------------------------------------------------------------------------- F.6 FOR proposals seeking authorization to file required documents/other formalities -------------------------------------------------------------------------------- F.7 FOR proposals to authorize the corporate board to ratify and execute approved resolutions -------------------------------------------------------------------------------- F.8 FOR proposals appointing inspectors of elections -------------------------------------------------------------------------------- F.9 FOR proposals electing a chair of the meeting -------------------------------------------------------------------------------- F.10 FOR proposals to permit "virtual" shareholder meetings over the Internet -------------------------------------------------------------------------------- F.11 AGAINST proposals to require rotating sites for shareholder meetings -------------------------------------------------------------------------------- 14 G. Investment Companies These proposals relate to proxy issues that are associated solely with holdings of shares of investment companies, including, but not limited to, investment companies for which BlackRock provides investment advisory, administrative and/or other services. As with other types of companies, the Committee believes that a fund's Board of Directors (rather than its shareholders) is best-positioned to set fund policy and oversee management. However, the Committee opposes granting Boards of Directors authority over certain matters, such as changes to a fund's investment objective, that the Investment Company Act of 1940 envisions will be approved directly by shareholders. The Committee's general policy is to vote: -------------------------------------------------------------------------------- G.1 FOR nominees for director of mutual funds in uncontested elections, except for nominees who o have missed at least two meetings and, as a result, attended less than 75% of meetings of the Board of Directors and its committees the previous year, unless the nominee missed the meeting due to illness or fund business o ignore a shareholder proposal that was approved by either a majority of the shares outstanding in any year or by the majority of votes cast for two consecutive years o are interested directors who serve on the audit or nominating committees or on a full Board that does not have such committees composed exclusively of independent directors o on a case-by-case basis, have served as directors of companies with allegedly poor corporate governance -------------------------------------------------------------------------------- G.2 FOR the establishment of new series or classes of shares -------------------------------------------------------------------------------- G.3 AGAINST proposals to change a fund's investment objective to nonfundamental -------------------------------------------------------------------------------- G.4 FOR proposals to establish a master-feeder structure or authorizing the Board to approve a master-feeder structure without a further shareholder vote -------------------------------------------------------------------------------- G.5 AGAINST a shareholder proposal for the establishment of a director ownership requirement -------------------------------------------------------------------------------- G.6 FOR classified boards of closed-end investment companies -------------------------------------------------------------------------------- 15 H. Environmental and Social Issues These are shareholder proposals to limit corporate conduct in some manner that relates to the shareholder's environmental or social concerns. The Committee generally believes that annual shareholder meetings are inappropriate forums for the discussion of larger social issues, and opposes shareholder resolutions "micromanaging" corporate conduct or requesting release of information that would not help a shareholder evaluate an investment in the corporation as an economic matter. While the Committee is generally supportive of proposals to require corporate disclosure of matters that seem relevant and material to the economic interests of shareholders, the Committee is generally not supportive of proposals to require disclosure of corporate matters for other purposes. The Committee's general policy is to vote: -------------------------------------------------------------------------------- H.1 AGAINST proposals seeking to have companies adopt international codes of conduct -------------------------------------------------------------------------------- H.2 AGAINST proposals seeking to have companies provide non-required reports on: o environmental liabilities; o bank lending policies; o corporate political contributions or activities; o alcohol advertising and efforts to discourage drinking by minors; o costs and risk of doing business in any individual country; o involvement in nuclear defense systems -------------------------------------------------------------------------------- H.3 AGAINST proposals requesting reports on Maquiladora operations or on CERES principles -------------------------------------------------------------------------------- H.4 AGAINST proposals seeking implementation of the CERES principles -------------------------------------------------------------------------------- 16 Notice to Clients BlackRock will make records of any proxy vote it has made on behalf of a client available to such client upon request.(11) BlackRock will use its best efforts to treat proxy votes of clients as confidential, except as it may decide to best serve its clients' interests or as may be necessary to effect such votes or as may be required by law. BlackRock encourage clients with an interest in particular proxy voting issues to make their views known to BlackRock, provided that, in the absence of specific written direction from a client on how to vote that client's proxies, BlackRock reserves the right to vote any proxy in a manner it deems in the best interests of its clients, as it determines in its sole discretion. These policies are as of the date indicated on the cover hereof. The Committee may subsequently amend these policies at any time, without notice. ---------- (11) Such request may be made to the client's portfolio or relationship manager or addressed in writing to Secretary, BlackRock Equity Investment Policy Oversight Committee, Legal and Compliance Department, BlackRock Inc., 40 East 52nd Street, New York, New York 10022. 17 Item 8 - Portfolio Managers of Closed-End Management Investment Companies - as of October 31, 2007. (a)(1) BlackRock MuniYield Insured Fund, Inc. is managed by a team of investment professionals comprised of William R. Bock, Director at BlackRock, Theodore R. Jaeckel, Jr., CFA, Managing Director at BlackRock, and Walter O'Connor, Managing Director at BlackRock. Each is a member of BlackRock's municipal tax-exempt management group. Mr. Jaeckel and Mr. O'Connor are responsible for setting the Fund's overall investment strategy and overseeing the management of the Fund. Mr. Bock is the Fund's lead portfolio manager and is responsible for the day-to-day management of the Fund's portfolio and the selection of its investments. Messrs. Jaeckel and O'Connor have been members of the Fund's management team since 2006 and Mr. Bock has been the Fund's portfolio manager since 1993. Mr. Jaeckel joined BlackRock in 2006. Prior to joining BlackRock, he was a Managing Director (Municipal Tax-Exempt Fund Management) of Merrill Lynch Investment Managers, L.P. ("MLIM") from 2005 to 2006 and a Director of MLIM from 1997 to 2005. He has been a portfolio manager with BlackRock or MLIM since 1991. Mr. O'Connor joined BlackRock in 2006. Prior to joining BlackRock, he was a Managing Director (Municipal Tax-Exempt Fund Management) of MLIM from 2003 to 2006 and was a Director of MLIM from 1997 to 2002. He has been a portfolio manager with BlackRock or MLIM since 1991. Mr. Bock joined BlackRock in 2006. Prior to joining BlackRock, he was a Director (Municipal Tax-Exempt Fund Management) of MLIM from 2005 to 2006. He has been a portfolio manager with BlackRock or MLIM since 1989.

BlackRock 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, BlackRock furnishes investment management and advisory services to numerous clients in addition to the Fund, and BlackRock 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 BlackRock, or in which portfolio managers have a personal interest in the receipt of such fees), which may be the same as or different from those made to the Fund. In addition, BlackRock, its affiliates and any officer, director, stockholder or employee may or may not have an interest in the securities whose purchase and sale BlackRock recommends to the Fund. BlackRock, or any of its affiliates, or any officer, director, stockholder, employee or any member of their families may take different actions than those recommended to the Fund by BlackRock with respect to the same securities. Moreover, BlackRock may refrain from rendering any advice or services concerning securities of companies of which any of BlackRock's (or its affiliates') officers, directors or employees are directors or officers, or companies as to which BlackRock or any of its affiliates or the officers, directors and employees of any of them has any substantial economic interest or possesses material non-public information. Each portfolio manager also may manage accounts whose investment strategies may at times be opposed to the strategy utilized for the Fund. In this connection, it should be noted that certain portfolio managers currently manage certain accounts that are subject to performance fees. In addition, certain portfolio managers assist in managing certain hedge funds and may be entitled to receive a portion of any incentive fees earned on such funds and a portion of such incentive fees may be voluntarily or involuntarily deferred. Additional portfolio managers may in the future manage other such accounts or funds and may be entitled to receive incentive fees. As a fiduciary, BlackRock owes a duty of loyalty to its clients and must treat each client fairly. When BlackRock purchases or sells securities for more than one account, the trades must be allocated in a manner consistent with its fiduciary duties. BlackRock attempts to allocate investments in a fair and equitable manner among client accounts, with no account receiving preferential treatment. To this end, BlackRock has adopted a policy that is intended to ensure that investment opportunities are allocated fairly and equitably among client accounts over time. This policy also seeks to achieve reasonable efficiency in client transactions and provide BlackRock with sufficient flexibility to allocate investments in a manner that is consistent with the particular investment discipline and client base. (a)(3) As of October 31, 2007: Portfolio Manager Compensation The portfolio manager compensation program of BlackRock is critical to BlackRock's ability to attract and retain the most talented asset management professionals. This program ensures that compensation is aligned with maximizing investment returns and it provides a competitive pay opportunity for competitive performance. Compensation Program The elements of total compensation for BlackRock portfolio managers are: fixed base salary, annual performance-based cash and stock compensation (cash and stock bonus) and other benefits. BlackRock has balanced these components of pay to provide portfolio managers with a powerful incentive to achieve consistently superior investment performance. By design, portfolio manager compensation levels fluctuate -- both up and down -- with the relative investment performance of the portfolios that they manage. Base Salary Under the BlackRock approach, like that of many asset management firms, fixed base salaries represent a relatively small portion of a portfolio manager's total compensation. This approach serves to enhance the motivational value of the performance-based (and therefore variable) compensation elements of the compensation program. Performance-Based Compensation BlackRock believes that the best interests of investors are served by recruiting and retaining exceptional asset management talent and managing their compensation within a consistent and disciplined framework that emphasizes pay for performance in the context of an intensely competitive market for talent. To that end, the portfolio manager incentive compensation is based on a formulaic compensation program. BlackRock's formulaic portfolio manager compensation program includes: pre-tax investment performance relative to the appropriate competitors or benchmarks over 1-, 3- and 5-year performance periods and a measure of operational efficiency. If a portfolio manager's tenure is less than 5 years, performance periods will reflect time in position. Portfolio managers are compensated based on products they manage. For these purposes, the performance of the Fund is compared to the Lipper Closed-end Leveraged Insured Municipal Debt Funds classification. A smaller discretionary element of portfolio manager compensation may include consideration of: financial results, expense control, profit margins, strategic planning and implementation, quality of client service, market share, corporate reputation, capital allocation, compliance and risk control, leadership, workforce diversity, supervision, technology and innovation. All factors are considered collectively by BlackRock management. Cash Bonus Performance-based compensation is distributed to portfolio managers in a combination of cash and stock. Typically, the cash bonus, when combined with base salary, represents more than 60% of total compensation for the portfolio managers. Stock Bonus A portion of the dollar value of the total annual performance-based bonus is paid in restricted shares of stock of BlackRock, Inc. (the "Company"). Paying a portion of annual bonuses in stock puts compensation earned by a portfolio manager for a given year "at risk" based on the Company's ability to sustain and improve its performance over future periods. The ultimate value of stock bonuses is dependent on future Company stock price performance. As such, the stock bonus aligns each portfolio manager's financial interests with those of the Company's shareholders and encourages a balance between short-term goals and long-term strategic objectives. Management strongly believes that providing a significant portion of competitive performance-based compensation in stock is in the best interests of investors and shareholders. This approach ensures that portfolio managers participate as shareholders in both the "downside risk" and "upside opportunity" of the Company's performance. Portfolio managers, therefore, have a direct incentive to protect the Company's reputation for integrity. Other Benefits Portfolio managers are also eligible to participate in broad-based plans offered generally to BlackRock employees, including broad-based retirement, 401(k), health, and other employee benefit plans. For example, BlackRock, Inc. has created a variety of incentive savings plans in which BlackRock 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 6% of eligible pay contributed to the plan capped at $4,000 per year, and a company retirement contribution equal to 3% of eligible compensation, plus an additional contribution of 2% for any year in which BlackRock has positive net operating income. The RSP offers a range of investment options, including registered investment companies managed by the firm. Company contributions follow the investment direction set by participants for their own contributions or absent, employee investment direction, are invested into a stable value fund. The ESPP allows for investment in BlackRock 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 or a dollar value of $25,000. Each portfolio manager is eligible to participate in these plans. (a)(4) Beneficial Ownership of Securities. As of October 31, 2007, none of Messrs. Bock, Jaeckel or O'Connor beneficially owned any stock issued by the Fund.
