2 SEMI-ANNUAL REPORT AUGUST 31, 2009

Dear Shareholder

The past 12 months reveal two distinct economic and market backdrops — one of extreme investor pessimism and decided weakness, and another of increased optimism amid growing signs of recovery. The start of the period was characterized by the former. September through December 2008 saw the surge of the economic storm that sparked the worst recession in decades. The months featured, among others, the infamous collapse of Lehman Brothers, uniformly poor economic data and plummeting investor confidence that resulted in massive government intervention (on a global scale) in the financial system and the economy. The tide turned dramatically in March 2009, however, on the back of new US government initiatives, as well as better-than-expected economic data and upside surprises in corporate earnings.

In this environment, US equities contended with extraordinary volatility, posting steep declines through mid-March before embarking on a rally that resulted in strong year-to-date returns for all major indexes. June saw a brief correction, though it appeared to be induced more by profit-taking and portfolio rebalancing than by a change in the economic outlook. The experience in international markets was similar to that in the United States. Notably, emerging markets staged a strong comeback in 2009 as these areas of the globe have generally seen a stronger acceleration in economic activity.

In fixed income markets, the flight-to-safety premium in Treasury securities prevailed during the equity market downturn, but more recently, ongoing concerns about deficit spending, debt issuance, inflation and dollar weakness have kept Treasury yields higher. At the same time, relatively attractive yields and distressed valuations among non-Treasury assets, coupled with a more favorable macro environment, drew in sidelined investors and triggered a sharp recovery in these sectors. This was particularly evident in the high yield sector, which has firmly outpaced all other taxable asset classes since the start of 2009. The municipal bond market enjoyed strong returns in 2009 as well, buoyed by a combination of attractive valuations, robust retail investor demand and a slowdown in forced selling. Moreover, the Build America Bond program has alleviated supply pressures, creating a more favorable technical environment. In particular, August marked the municipal market’s best monthly performance in more than 20 years, as the asset class has regained year-to-date all that was lost during 2008.

Overall, results for the major benchmark indexes were mixed. Higher-risk assets (i.e., equities and high yield bonds) and Treasuries reflected a bifurcated market, while less-risky fixed income investments posted stable, modest returns.

Fund Summary as of August 31, 2009 BlackRock Corporate High Yield Fund, Inc.

Investment Objective

BlackRock Corporate High Yield Fund, Inc. (COY) (the “Fund”) seeks to provide shareholders with current income with a secondary objective of providing shareholders with capital appreciation. The Fund seeks to achieve its objective by investing primarily in a diversified portfolio of fixed-income securities that are rated below investment grade by the established rating services (Ba or lower by Moody’s Investors Service, Inc. (“Moody’s”) or BB or lower by Standard & Poor’s Corporation (“S&P’s”)) or are unrated securities of comparable quality.

          No assurance can be given that the Fund’s investment objective will be achieved.

Performance

For the six months ended August 31, 2009, the Fund returned 66.35% based on market price and 49.85% based on net asset value (“NAV”). For the same period, the closed-end Lipper High Current Yield Funds (Leveraged) category posted an average return of 50.49% on a market price basis and 40.06% on a NAV basis. During the period, the Fund moved from a discount to a premium to NAV, which accounts for the difference between performance based on price and performance based on NAV. The period featured the largest six-month rise in high yield market history, providing a good environment for bottom-up security selection, with no emphasis on any one sector. We gradually decreased cash and increased the Fund’s risk as market conditions dictated. Overall, there was a wide dispersion of returns among the Fund’s Lipper competitors, as many funds did well while others struggled with credit issues or retained too defensive a strategy. Security selection was the primary contributor to performance during the period. The Fund maintains a 16% position in floating rate loan interests, which detracted as these securities underperformed high yield corporate bonds. During the period, the Fund moved from a larger cash balance to a balance of less than 3%, which has benefited performance in the rising market.

SEMI-ANNUAL REPORT AUGUST 31, 2009 5

Fund Summary as of August 31, 2009	BlackRock Debt Strategies Fund, Inc.
Investment Objective

BlackRock Debt Strategies Fund, Inc. (DSU) (the “Fund”) seeks to provide current income by investing primarily in a diversified portfolio of US companies’ debt instruments, including corporate loans, that are rated in the lower rating categories of the established rating services (Ba or lower by Moody’s or BB or lower by S&P’s) or unrated debt instruments of comparable quality.

     No assurance can be given that the Fund’s investment objective will be achieved.

     Performance

For the six months ended August 31, 2009, the Fund returned 74.49% based on market price and 51.87% based on NAV. For the same period, the closed-end Lipper High Current Yield Funds (Leveraged) category posted an average return of 50.49% on a market price basis and 40.06% on a NAV basis. All returns reflect reinvestment of dividends. The Fund moved from a discount to a premium to NAV, which accounts for the difference between performance based on price and performance based on NAV. The Fund benefited from a slight bias to lower-quality credits, which outperformed higher-quality credits during the six months. Unlike its Lipper peers, the Fund invests in floating rate loan interests as well as high yield bonds. Loans underperformed bonds for the period; consequently, the Fund’s 41% average allocation to loans detracted from relative performance. The Fund also maintained a relatively low level of leverage (less than 15%), which detracted in the strong market environment. During the period, the Fund moved from a larger cash balance to a balance of less than 1%, which has benefited performance in the rising market.

Investment Objective

BlackRock Senior High Income Fund, Inc. (ARK) (the “Fund”) seeks to provide shareholders with as high a level of current income as is consistent with its investment policies and prudent investment management by investing principally in senior debt obligations of companies, including corporate loans made by banks and other financial institutions and both privately placed and publicly offered corporate bonds and notes.

          No assurance can be given that the Fund’s investment objective will be achieved.

Performance

For the six months ended August 31, 2009, the Fund returned 51.37% based on market price and 43.72% based on NAV.

8 SEMI-ANNUAL REPORT AUGUST 31, 2009

The Benefits and Risks of Leveraging

The Funds may utilize leverage to seek to enhance the yield and NAV. However, these objectives cannot be achieved in all interest rate environments.

The Funds may utilize leverage through borrowings or issuance of short-term debt. In general, the concept of leveraging is based on the premise that the cost of assets to be obtained from leverage will be based on short-term interest rates, which normally will be lower than the income earned by each Fund on its longer-term portfolio investments. To the extent that the total assets of each Fund (including the assets obtained from leverage) are invested in higher-yielding portfolio investments, each Fund’s shareholders will benefit from the incremental net income.

The interest earned on securities purchased with the proceeds from leverage is paid to shareholders in the form of dividends, and the value of these portfolio holdings is reflected in the per share NAV. However, in order to benefit shareholders, the yield curve must be positively sloped; that is, short-term interest rates must be lower than long-term interest rates. If the yield curve becomes negatively sloped, meaning short-term interest rates exceed long-term interest rates, income to shareholders will be lower than if the Funds had not used leverage.

To illustrate these concepts, assume a Fund’s capitalization is $100 million and it issues debt securities for an additional $30 million, creating a total value of $130 million available for investment in long-term securities. If prevailing short-term interest rates are 3% and long-term interest rates are 6%, the yield curve has a strongly positive slope. In this case, the Fund pays interest expense on the $30 million of debt securities based on the lower short-term interest rates. At the same time, the securities purchased by the Fund with assets received from the debt securities issuance earn the income based on long-term interest rates. In this case, the interest expense of the debt securities is significantly lower than the income earned on the Fund’s long-term investments, and therefore the shareholders are the beneficiaries of the incremental net income.

If short-term interest rates rise, narrowing the differential between short-term and long-term interest rates, the incremental net income pickup will be reduced or eliminated completely. Furthermore, if prevailing short-term interest rates rise above long-term interest rates of 6%, the yield curve has a negative slope. In this case, the Fund pays interest expense on the higher short-term interest rates whereas the Fund’s total portfolio earns income based on lower long-term interest rates.

Furthermore, the value of the Fund’s portfolio investments generally varies inversely with the direction of long-term interest rates, although other factors can influence the value of portfolio investments. In contrast, the redemption value of the Fund’s debt securities do not fluctuate in relation to interest rates. As a result, changes in interest rates can influence the Fund’s NAV positively or negatively in addition to the impact on Fund performance from leverage from debt securities.

The use of leverage may enhance opportunities for increased income to the Funds and shareholders, but as described above, it also creates risks as short- or long-term interest rates fluctuate. Leverage also will generally cause greater changes in each Fund’s NAV, market price and dividend rate than a comparable portfolio without leverage. If the income derived from securities purchased with assets received from leverage exceeds the cost of leverage, each Fund’s net income will be greater than if leverage had not been used. Conversely, if the income from the securities purchased is not sufficient to cover the cost of leverage, each Fund’s net income will be less than if leverage had not been used, and therefore the amount available for distribution to shareholders will be reduced. A Fund may be required to sell portfolio securities at inopportune times at distressed values in order to comply with regulatory requirements applicable to the use of leverage or as required by the terms of leverage instruments which may cause a Fund to incur losses. The use of leverage may limit a Fund’s ability to invest in certain types of securities or use certain types of hedging strategies. A Fund will incur expenses in connection with the use of leverage, all of which are borne by the shareholders and may reduce income.

Under the Investment Company Act of 1940, the Funds are permitted to borrow through a credit facility and the issuance of short-term debt securities up to 33¹/₃% of their total managed assets. As of August 31, 2009, the Funds had outstanding leverage from credit facility borrowings as a percentage of total managed assets as follows:

	Percent of Leverage
COY	16	%
CYE	18	%
DSU	12	%
FRB	16	%
ARK	8	%

Derivative Financial Instruments

The Funds may invest in various derivative instruments, including swap agreements, foreign currency exchange contracts and options, as specified in Note 2 of the Notes to Financial Statements, which constitute forms of economic leverage. Such instruments are used to obtain exposure to a market without owning or taking physical custody of securities or to hedge market and/or interest rate risks. Such derivative instruments involve risks, including the imperfect correlation between the value of a derivative instrument and the underlying asset, possible default of the counterparty to the transaction and illiquidity of the derivative instrument. A Fund’s ability to successfully use a derivative instrument depends on the investment advisor’s ability to accurately predict pertinent market movements, which cannot be assured. The use of derivative instruments may result in losses greater than if they had not been used, may require the Funds to sell or purchase portfolio securities at inopportune times or for distressed values, may limit the amount of appreciation the Funds can realize on an investment or may cause the Funds to hold a security that they might otherwise sell. The Funds’ investments in these instruments are discussed in detail in the Notes to Financial Statements.

•	Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” clarifies the definition of fair value, establishes a framework for measuring fair values and requires additional disclosures about the use of fair value measurements. Various inputs are used in determining the fair value of investments, which are as follows:
	•	Level 1 — price quotations in active markets/exchanges for identical securities
	•	Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs)
	•	Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments)
	The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For information about the Fund’s policy regarding valuation of investments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements.

The following table summarizes the inputs used as of August 31, 2009 in determining the fair valuation of the Fund’s investments:

•	Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” clarifies the definition of fair value, establishes a framework for measuring fair values and requires additional disclosures about the use of fair value measurements. Various inputs are used in determining the fair value of investments, which are as follows:
	•	Level 1 — price quotations in active markets/exchanges for identical securities
	•	Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs)
	•	Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments)
	The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

• Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” clarifies the definition of fair value, establishes a framework for measuring fair values and requires additional disclosures about the use of fair value measurements. Various inputs are used in determining the fair value of investments, which are as follows:

• Level 1 — price quotations in active markets/exchanges for identical securities

• Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs)

• Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For information about the Fund’s policy regarding valuation of investments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements.

The following table summarizes the inputs used as of August 31, 2009 in determining the fair valuation of the Fund’s investments:

• Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” clarifies the definition of fair value, establishes a framework for measuring fair values and requires additional disclosures about the use of fair value measurements. Various inputs are used in determining the fair value of investments, which are as follows:

• Level 1 — price quotations in active markets/exchanges for identical securities

• Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs)

• Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For information about the Fund’s policy regarding valuation of investments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements.

The following table summarizes the inputs used as of August 31, 2009 in determining the fair valuation of the Fund’s investments:

	•	Level 1 — price quotations in active markets/exchanges for identical securities
	•	Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs)

Each of the Funds is organized as a Maryland corporation. The Funds’ financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, 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 values of their Common Shares on a daily basis.

The following is a summary of significant accounting policies followed by the Funds:

Valuation of Investments: The Funds value their bond investments on the basis of last available bid prices or current market quotations provided by dealers or pricing services selected under the supervision of each Fund’s Board of Directors (the “Board”). Floating rate loan interests are valued at the mean between the last available bid prices from one or more brokers or dealers as obtained from a pricing service. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrixes, market transactions in comparable investments, various relationships observed in the market between investments and calculated yield measures based on valuation technology commonly employed in the market for such investments. Swap agreements are valued utilizing quotes received daily by the Funds’ pricing service or through brokers which are derived using daily swap curves and trades of underlying securities. Short-term securities with maturities less than 60 days may be valued at amortized cost, which approximates fair value. The Funds’ value their investments in Cash Sweep Series, each of BlackRock Liquidity Series, LLC at fair value, which is ordinarily based upon their pro-rata ownership in the net assets of the underlying fund.

Equity investments traded on a recognized securities exchange or the NASDAQ Global Market System are valued at the last reported sale price that day or the NASDAQ official closing price, if applicable. For equity investments traded on more than one exchange, the last reported sale price on the exchange where the stock is primarily traded is used. Equity investments traded on a recognized exchange for which there were no sales on that day are valued at the last available bid price. If no bid price is available, the prior day’s price will be used, unless it is determined that such prior day’s price no longer reflects the fair value of the security.

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. An exchange-traded option for which there is no mean price is valued at the last bid price. If no bid price is available, the prior day’s price will be used, unless it is determined that such prior day’s price no longer reflects the fair value of the option. Over-the-counter (“OTC”) options are valued by an independent pricing service using a mathematical model which incorporates a number of market data factors, such as the trades and prices of the underlying securities.

In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the market value of such investment or are not available, the investment will be valued by a method approved by the Board as reflecting fair value (“Fair Value Assets”). When determining the price for Fair Value Assets, the investment advisor and/or sub-advisor seeks to determine the price that the Funds might reasonably expect to receive from the current sale of that asset in an arm’s-length transaction. Fair value determinations shall be based upon all available factors that the investment advisor and/or sub-advisor deems relevant. The pricing of all Fair Value Assets is subsequently reported to the Board or a committee thereof.

Generally, trading in foreign securities is substantially completed each day at various times prior to the close of business on the New York Stock Exchange (“NYSE”). The values of such securities used in computing the net assets of each Fund are determined as of such times. Foreign currency exchange rates will be determined as of the close of business on the NYSE. Occasionally, events affecting the values of such securities and such exchange rates may occur between the times at which they are determined and the close of business on the NYSE that may not be reflected in the computation of the Fund’s net assets. If events (for example, a company announcement, market volatility or a natural disaster) occur during such periods that are expected to materially affect the value of such securities, those securities will be valued at their fair value as determined in good faith by the Board or by the investment advisor using a pricing service and/or procedures approved by the Board. Foreign currency exchange contracts are valued at the mean between the bid and ask prices. Interpolated values are derived when the settlement date of the contract is an interim date for which quotations are not available.

Foreign Currency Transactions: Foreign currency amounts are translated into United States dollars on the following basis: (i) market value of investment securities, assets and liabilities at the current rate of exchange; and (ii) purchases and sales of investment securities, income and expenses at the rates of exchange prevailing on the respective dates of such transactions.

The Funds report foreign currency related transactions as components of realized gains for financial reporting purposes, whereas such components are treated as ordinary income for federal income tax purposes.

Capital Trusts: These securities are typically issued by corporations, generally in the form of interest-bearing notes with preferred securities characteristics, or by an affiliated business trust of a corporation, generally in the form of beneficial interests in subordinated debentures or similarly structured securities. The securities can be structured as either fixed or adjustable coupon securities that can have either a perpetual or stated maturity date. Dividends can be deferred without creating an event of default or acceleration, although maturity cannot take place unless all cumulative payment obligations have been met. The deferral of payments does not affect the purchase or sale of these securities in the open market. Payments on these securities are treated as interest rather than dividends for Federal income tax purposes. These securities can have a rating that is slightly below that of the issuing company’s senior debt securities.

SEMI-ANNUAL REPORT AUGUST 31, 2009 55

Notes to Financial Statements (continued)

Preferred Stock: Certain Funds may invest in preferred stocks. Preferred stock has a preference over common stock in liquidation (and generally in receiving dividends as well) but is subordinated to the liabilities of the issuer in all respects. As a general rule, the market value of preferred stock with a fixed dividend rate and no conversion element varies inversely with interest rates and perceived credit risk, while the market price of convertible preferred stock generally also reflects some element of conversion value. Because preferred stock is junior to debt securities and other obligations of the issuer, deterioration in the credit quality of the issuer will cause greater changes in the value of a preferred stock than in a more senior debt security with similar stated yield characteristics. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Floating Rate Loans: The Funds may invest in floating rate loans, which are generally non-investment grade, made by banks, other financial institutions and privately and publicly offered corporations. Floating rate loans are senior in the debt structure of a corporation. Floating rate loans generally pay interest at rates that are periodically determined by reference to a base lending rate plus a premium. The base lending rates are generally (i) the lending rate offered by one or more European banks, such as LIBOR (London InterBank Offered Rate), (ii) the prime rate offered by one or more US banks or (iii) the certificate of deposit rate. The Funds consider these investments to be investments in debt securities for purposes of their investment policies.

The Funds earn and/or pay facility and other fees on floating rate loans. Other fees earned/paid include commitment, amendment, consent, commissions and prepayment penalty fees. Facility, amendment and consent fees are typically amortized as premium and/or accreted as discount over the term of the loan. Commitment, commission and various other fees are recorded as income. Prepayment penalty fees are recognized on the accrual basis. When a Fund buys a floating rate loan it may receive a facility fee and when it sells a floating rate loan it may pay a facility fee. On an ongoing basis, the Funds may receive a commitment fee based on the undrawn portion of the underlying line of credit portion of a floating rate loan. In certain circumstances, the Funds may receive a prepayment penalty fee upon the prepayment of a floating rate loan by a borrower. Other fees received by the Funds may include covenant waiver fees and covenant modification fees.

The Funds may invest in multiple series or tranches of a loan. A different series or tranche may have varying terms and carry different associated risks.

Floating rate loans are usually freely callable at the issuer’s option. The Funds may invest in such loans in the form of participations in loans (“Participations”) and assignments of all or a portion of loans from third parties. Participations typically will result in the Funds having a contractual relationship only with the lender, not with the borrower. The Funds will have the right to receive payments of principal, interest and any fees to which they are entitled only from the lender selling the Participation and only upon receipt by the lender of the payments from the borrower.

In connection with purchasing Participations, the Funds generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loans, nor any rights of offset against the borrower, and the Funds may not benefit directly from any collateral supporting the loan in which it has purchased the Participation.

As a result, the Funds will assume the credit risk of both the borrower and the lender that is selling the Participation. The Funds’ investments in loan participation interests involve the risk of insolvency of the financial intermediaries who are parties to the transactions. In the event of the insolvency of the lender selling the Participation, the Funds may be treated as general creditor of the lender and may not benefit from any offset between the lender and the borrower.

Zero-Coupon Bonds: Certain Funds may invest in zero-coupon bonds, which are normally issued at a significant discount from face value and do not provide for periodic interest payments. Zero-coupon bonds may experience greater volatility in market value than similar maturity debt obligations which provide for regular interest payments.

Segregation and Collateralization: In cases in which the 1940 Act and the interpretive positions of the Securities and Exchange Commission (“SEC”) require that each Fund either delivers collateral or segregates assets in connection with certain investments (e.g., foreign currency exchange contracts and swaps) each Fund will, consistent with SEC rules and/or certain interpretive letters issued by the SEC, segregate collateral or designate on its books and records cash or other liquid securities having a market value at least equal to the amount that would otherwise be required to be physically segregated. Furthermore, based on requirements and agreements with certain exchanges and third party broker-dealers, each party has requirements to deliver/deposit securities as collateral for certain investments (e.g., swaps). As part of these agreements, when the value of these investments achieves a previously agreed upon value (minimum transfer amount), each party may be required to deliver additional collateral.

Investment Transactions and Investment Income: For financial reporting purposes, investment 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 recorded on the accrual basis. Each Fund amortizes all premiums and discounts on debt securities.

Dividends and Distributions: Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. If the total dividends and distributions made in any tax year exceed net investment income and accumulated realized capital gains, a portion of the total distribution may be treated as a tax return of capital.

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. Under the applicable foreign tax laws, a withholding tax may be imposed on interest, dividends and capital gains at various rates.

Each Fund files US federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Funds’ US federal tax returns remains open for each of the three years

56 SEMI-ANNUAL REPORT AUGUST 31, 2009

Notes to Financial Statements (continued)

ended May 31, 2008 and the period ended February 28, 2009 for Corporate High Yield and Corporate High Yield III, and for each of the four years ended February 28, 2009 for Debt Strategies, Floating Rate Income Strategies II and Senior High Income. The statutes of limitations on the Funds’ state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Recent Accounting Pronouncement: In June 2009, Statement of Financial Accounting Standards No. 166, “Accounting for Transfers of Financial Assets — an amendment of FASB Statement No. 140” (“FAS 166”), was issued. FAS 166 is intended to improve the relevance, representational faithfulness and comparability of the information that a reporting entity provides in its financial statements about a transfer of financial assets; the effects of a transfer on its financial position, financial performance, and cash flows; and a transferor’s continuing involvement, if any, in transferred financial assets. FAS 166 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2009. Earlier application is prohibited. The recognition and measurement provisions of FAS 166 must be applied to transfers occurring on or after the effective date. Additionally, the disclosure provisions of FAS 166 should be applied to transfers that occurred both before and after the effective date of FAS 166. The impact of FAS 166 on the Funds’ financial statement disclosures, if any, is currently being assessed.

Deferred Compensation and BlackRock Closed-End Share Equivalent Investment Plan: Under the deferred compensation plan approved by each Fund’s Board, non-interested Directors (“Independent Directors”) may defer a portion of their annual complex-wide compensation. Deferred amounts earn an approximate return as though equivalent dollar amounts have been invested in common shares of other certain BlackRock Closed-End Funds selected by the Independent Directors. This has approximately the same economic effect for the Independent Directors as if the Independent Directors had invested the deferred amounts directly in other certain BlackRock Closed-End Funds.

The deferred compensation plan is not funded and obligations thereunder represent general unsecured claims against the general assets of each Fund. Each Fund may, however, elect to invest in Common Shares of other certain BlackRock Closed-End Funds selected by the Independent Directors in order to match its deferred compensation obligations. Investments to cover each Fund’s deferred compensation liability, if any, are included in other assets in the Statements of Assets and Liabilities. Dividends and distributions from the BlackRock Closed-End Fund investments under the plan are included in income — affiliated in the Statements of Operations.

Other: Expenses directly related to a Fund are charged to that Fund. Other operating expenses shared by several funds are pro-rated among those funds on the basis of relative net assets or other appropriate methods.

2. Derivative Financial Instruments:

The Funds may engage in various portfolio investment strategies both to increase the returns of the Funds and to economically hedge, or protect, their exposure to certain risks such as credit risk, equity risk, interest rate risk and foreign currency exchange rate risk. Losses may arise if the value of the contract decreases due to an unfavorable change in the value of the underlying security or if the counterparty does not perform under the contract. The Funds may mitigate counterparty risk through master netting agreements included within an International Swap and Derivatives Association, Inc. (“ISDA”) Master Agreement between a Fund and each of its counterparties. The ISDA Master Agreement allows each Fund to offset with its counterparty certain derivative financial instrument’s payables and/or receivables with collateral held with each counterparty. The amount of collateral moved to/from applicable coun-terparties is based upon minimum transfer amounts of up to $500,000. To the extent amounts due to the Funds from their counterparties are not fully collateralized contractually or otherwise, the Funds bear the risk of loss from counterparty non-performance. See Note 1 “Segregation and Collateralization” for information with respect to collateral practices.

The Funds’ maximum risk of loss from counterparty credit risk on over-the-counter derivatives is generally the aggregate unrealized gain in excess of any collateral pledged by the counterparty to the Funds. For over-the-counter purchased options, the Funds bear the risk of loss in the amount of the premiums paid and change in market value of the options should the counter-party not perform under the contracts. Options written by the Funds do not give rise to counterparty credit risk, as written options obligate the Funds to perform and not the counterparty. Certain ISDA Master Agreements allow counterparties to over-the-counter derivatives to terminate derivative contracts prior to maturity in the event a Fund’s net assets decline by a stated percentage or a Fund fails to meet the terms of its ISDA Master Agreements, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. Counterparty risk related to exchange-traded options is minimal because of the protection against defaults provided by the exchange on which they trade.

Foreign Currency Exchange Contracts: The Funds may enter into foreign currency exchange contracts as an economic hedge against either specific transactions or portfolio positions (foreign currency exchange rate risk). A foreign currency exchange contract is an agreement between two parties to buy and sell a currency at a set exchange rate on a future date. Foreign currency exchange contracts, when used by a Fund, help to manage the overall exposure to the foreign currency backing some of the investments held by a Fund. The contract is marked-to-market daily and the change in market value is recorded by a Fund as an unrealized gain or loss. When the contract is closed, a Fund records a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed. The use of foreign currency exchange contracts involves the risk that counterparties may not meet the terms of the agreement or unfavorable movements in the value of a foreign currency relative to the US dollar.

Options: The Funds may purchase and write call and put options to increase or decrease their exposure to underlying instruments. A call option gives the purchaser of the option the right (but not the obligation) to buy, and obligates the seller to sell (when the option is exercised), the underlying instrument at the exercise price at any time or at a specified time during the option period. A put option gives the holder the right to sell and obligates the writer to buy the underlying instrument at the exercise price at any time or at a specified time during the option period. When a Fund purchases (writes) an option, an amount equal to the premium paid (received) a Fund is reflected as an asset (liability) and an equivalent liability (asset). The amount of the asset (liability) is subsequently marked-to-market to reflect the current market value of the option purchased (written). When an instrument is purchased

SEMI-ANNUAL REPORT AUGUST 31, 2009 57

Notes to Financial Statements (continued)

or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the instrument acquired or deducted from (or added to) the proceeds of the instrument sold. When an option expires (or a Fund enters into a closing transaction), a 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 received or paid). When a Fund writes a call option, such option is “covered,” meaning that a Fund holds the underlying instrument subject to being called by the option counterparty, or cash in an amount sufficient to cover the obligation. When a Fund writes a put option, such option is covered by cash in an amount sufficient to cover the obligation.

In purchasing and writing options, a Fund bears the risk of an unfavorable change in the value of the underlying instrument or the risk that the Funds may not be able to enter into a closing transaction due to an illiquid market. Exercise of a written option could result in the Funds purchasing a security at a price different from the current market value. The Funds may execute transactions in both listed and over-the-counter options.

Swaps: The Funds may enter into swap agreements, in which a Fund and a counterparty agree to make periodic net payments on a specified notional amount. These periodic payments received or made by the Funds are recorded in the Statements of Operations as realized gains or losses, respectively. Swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). When the swap is terminated, the Fund will record a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Fund’s basis in the contract, if any. Swap transactions involve, to varying degrees, elements of interest rate, credit and market risk in excess of the amounts recognized in the Statements of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in interest rates and/or market values associated with these transactions.

• Credit default swaps — The Funds may enter into credit default swaps to manage their exposure to the market or certain sectors of the market, to reduce its risk exposure to defaults of corporate and/or sovereign issuers or to create exposure to corporate and/or sovereign issuers to which it is not otherwise exposed (credit risk). The Funds enter into credit default agreements to provide a measure of protection against the default of an issuer (as buyer of protection) and/or gain credit exposure to an issuer to which it is not otherwise exposed (as seller of protection). The Funds may either buy or sell (write) credit default swaps on single-name issuers (corporate or sovereign) or traded indexes. Credit default swaps on single-name issuers are agreements in which the buyer pays fixed periodic payments to the seller in consideration for a guarantee from the seller to make a specific payment should a negative credit event take place (e.g., bankruptcy, failure to pay, obligation accelerators, repudiation, moratorium or restructuring). Credit default swaps on traded indexes are agreements in which the buyer pays fixed periodic payments to the seller in consideration for a guarantee from the seller to make a specific payment should a write-down, principal or interest shortfall or default of all or individual underlying securities included in the index occurs. As a buyer, a Fund will either receive from the seller an amount equal to the notional amount of the swap and deliver the referenced security or underlying securities comprising of an index or receive a net settlement of cash equal to the notional amount of the swap less the recovery value of the security or underlying securities comprising of an index. As a seller (writer), a Fund will either pay the buyer an amount equal to the notional amount of the swap and take delivery of the referenced security or underlying securities comprising of an index or pay a net settlement of cash equal to the notional amount of the swap less the recovery value of the security or underlying securities comprising of an index.

3. Investment Advisory Agreement and Other Transactions with Affiliates:

The PNC Financial Services Group, Inc. (“PNC”) and Bank of America Corporation (“BAC”) are the largest stockholders of BlackRock, Inc. (“BlackRock”). Due to the ownership structure, PNC is an affiliate for 1940 Act purposes, but BAC is not.

Each Fund entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the “Manager”), the Funds’ investment advisor, an indirect, wholly owned subsidiary of BlackRock, to provide investment advisory and administration services.

The Manager is responsible for the management of each Fund’s portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of each Fund. For such services, each Fund pays the Manager a monthly fee at the following annual rates of the average daily value of each Fund’s net assets, plus the proceeds of any outstanding borrowings used for leverage:

COY	0.50	%
CYE	0.60	%
DSU	0.60	%
FRB	0.75	%
ARK	0.50	%

SEMI-ANNUAL REPORT AUGUST 31, 2009 59

Notes to Financial Statements (continued)

The Manager has entered into a separate sub-advisory agreement with BlackRock Financial Management, Inc. (“BFM”), an affiliate of the Manager, under which the Manager pays BFM, for services it provides, a monthly fee that is a percentage of the investment advisory fee paid by the Funds to the Manager.

The Manager has agreed to waive its advisory fee by the amount of investment advisory fees the Funds pay to the Manager indirectly through its investment in affiliated money market funds. This amount is shown as fees waived by advisor in the Statements of Operations.

For the six months ended August 31, 2009, the Funds reimbursed the Manager for certain accounting services, which are included in accounting services in the Statements of Operations were as follows:

	Reimbursement to Manager
COY	$2,181
CYE	$2,242
DSU	$4,232
FRB	$1,528
ARK	$1,979

Certain officers and/or directors of the Funds are officers and/or directors of BlackRock or its affiliates. The Funds reimburse the Manager for compensation paid to the Funds’ Chief Compliance Officer.

4. Investments:

Purchases and sales (including paydowns) of investments, excluding short-term securities, for the six months ended August 31, 2009 were as follows:

	Purchases		Sales
COY	$	86,948,446	$	84,639,100
CYE	$	97,047,976	$	91,160,449
DSU	$	115,195,401	$	148,776,628
FRB	$	52,942,447	$	49,540,382
ARK	$	66,767,286	$	86,318,320

5. Market and Credit Risk:

In the normal course of business, the Funds invest in securities and enter into transactions where risks exist due to fluctuations in the market (market risk) or failure of the issuer of a security to meet all its obligations (credit risk). The value of securities held by the Funds may decline in response to certain events, including those directly involving the issuers whose securities are owned by the Funds; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency and interest rate and price fluctuations. Similar to credit risk, the Funds may be exposed to counterparty risk, or the risk that an entity with which the Funds have unsettled or open transactions may default. Financial assets, which potentially expose the Funds to credit and counter-party risks, consist principally of investments and cash due from counterpar-ties. The extent of the Funds’ exposure to credit and counterparty risks with respect to these financial assets is approximated by their value recorded in the Funds’ Statements of Assets and Liabilities.

6. Capital Share Transactions:

Each Fund is authorized to issue 200 million shares, par value $0.10 per share, all of which were initially classified as Common Shares. At August 31, 2009, the shares owned by affiliates of the Manager of Floating Rate Income Strategies II were 8,182. The Board is authorized, however, to classify and reclassify any unissued shares without approval of shareholders. Shares issued and outstanding during the six months ended August 31, 2009 and the period ended February 28, 2009 increased by the following amounts as a result of dividend reinvestment.

	August 31, 2009	February 28, 2009
COY	41,825	—
CYE	2,744	—
DSU	289,050	499,727
ARK	—	75,664

Shares issued and outstanding remained constant for COY and CYE for the year ended May 31, 2008 and for FRB for the six months ended August 31, 2009 and the year ended February 28, 2009.

7. Commitments:

The Funds may invest in floating rate loans. In connection with these investments, the Funds may also enter into unfunded corporate loans (“commitments”). Commitments may obligate the Funds to furnish temporary financing to a borrower until permanent financing can be arranged. As of August 31, 2009, the Funds had the following unfunded loan commitments:

DSU

Borrower	Unfunded Commitment (000)	Value of Underlying Loans (000)
Smurfit-Stone Container Enterprises, Inc., Debtor in Possession Term Loan	$697	$666
Big West Oil LLC, Delayed Advance Loan	$162	$149

8. Borrowings:

On May 16, 2008, the Funds renewed their revolving credit and security Agreements (“Citicorp Agreement”) pursuant to a commercial paper asset securitization program with Citicorp North America, Inc. (“Citicorp”), as Agent, certain secondary backstop lenders and certain asset securitization conduits, as lenders (the “Lenders”). The agreement was renewed for one year and at the time of renewal had maximum limits as follows:

	Maximum Limit
COY	$	135,000,000
CYE	$	143,000,000
DSU	$	309,000,000
FRB	$	88,000,000
ARK	$	148,000,000

Under the Citicorp Agreement, the conduits funded advances to each Fund through the issuance of highly rated commercial paper as shown in the Statements of Assets and Liabilities as loan payable. Each Fund had granted a security interest in substantially all of its assets to, and in favor of, the Lenders as security for its obligations to the Lenders. The interest rate on each Fund’s borrowings was based on the interest rate carried by the commercial paper plus a program fee. In addition, each Fund paid a liquidity fee to the secondary backstop lenders and the agent. Under the Citicorp Agreement, the Funds were subject to certain conditions and covenants, which included among other things limitations on asset declines over prescribed time periods. As a result of the decline in net assets attributable to market conditions, certain terms of the facility were renegotiated effective December 5, 2008, for COY, CYE, DSU and ARK and effective December 31, 2008 for FRB, which included waivers of certain financial covenants by the Lenders, an increase in program and liquidity fees under the facility and a reduction of the maximum limits to as follows:

	Maximum Limit
COY	$	81,000,000
CYE	$	85,000,000
DSU	$	174,000,000
FRB	$	88,000,000
ARK	$	91,000,000

On March 5, 2009, the Funds terminated their revolving credit agreement with Citicorp and entered into a senior committed secured, 364-day revolving line of credit and a separate security agreement (the “SSB Agreement”) with State Street Bank and Fund Company (“SSB”). The SSB Agreement has the same maximum limits as the renegotiated limits under the Citigroup Agreement except for DSU which was lowered to $135,000,000 and FRB which lowered to $58,000,000. The Funds have granted a security interest in substantially all of its assets to SSB.

Advances are made by SSB to the Funds, at the Funds option (a) the higher of 1.0% above the Fed Effective Rate or 1.0% above the Overnight LIBOR Rate and (b) 1.0% above 7-day, 30-day, or 60-day LIBOR Rate. In addition, the Funds pay a facility fee and a commitment fee based upon SSBs total commitment to the Funds. The fees associated with each of the agreements are included in the Statements of Operations as borrowing costs. Advances to the Funds as of August 31, 2009 are shown in the Statements of Assets and Liabilities as loan payable.

The Funds may not declare dividends or make other distributions on shares or purchase any such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding short-term borrowings is less than 300%.

For the six months ended August 31, 2009, the daily weighted average interest rates under the revolving credit agreement were as follows:

	Daily Weighted Average Interest Rate
COY	1.29%
CYE	1.30%
DSU	1.30%
FRB	1.29%
ARK	1.30%

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements

The Board of Directors (each, a “Board” and, collectively, the “Boards,” and the members of which are referred to as “Board Members”) of each of BlackRock Corporate High Yield Fund, Inc. (“COY”), BlackRock Corporate High Yield Fund III, Inc. (“CYE”), BlackRock Debt Strategies Fund, Inc. (“DSU”), BlackRock Floating Rate Income Strategies Fund II, Inc. (“FRB”) and BlackRock Senior High Income Fund, Inc. (“ARK” and together with COY, CYE, DSU and FRB, each a “Fund,” and, collectively, the “Funds”) met on April 14, 2009 and May 28 – 29, 2009 to consider the approval of its respective Fund’s investment advisory agreement (each, an “Advisory Agreement”) with BlackRock Advisors, LLC (the “Manager”), each Fund’s investment advisor. Each Board also considered the approval of the sub-advisory agreement (each, a “Sub-Advisory Agreement”) between its respective Fund, the Manager and BlackRock Financial Management, Inc. (the “Sub-Advisor”). The Manager and the Sub-Advisor are referred to herein as “BlackRock.” The Advisory Agreements and the Sub-Advisory Agreements are referred to herein as the “Agreements.” Unless otherwise indicated, references to actions taken by the “Board” or the “Boards” shall mean each Board acting independently with respect to its respective Fund.

Activities and Composition of the Boards

Each Board consists of twelve individuals, ten of whom are not “interested persons” of the Funds as defined in the Investment Company Act of 1940, as amended (the “1940 Act”) (the “Independent Board Members”). The Board Members of each Fund are responsible for the oversight of the operations of such Fund and perform the various duties imposed on the directors of investment companies by the 1940 Act. The Independent Board Members have retained independent legal counsel to assist them in connection with their duties. The Chairman of each Board is an Independent Board Member. Each Board has established five standing committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee, a Performance Oversight Committee and an Executive Committee, each of which is composed of Independent Board Members (except for the Executive Committee, which has one interested Board Member) and is chaired by an Independent Board Member. In addition, each Board has established an Ad Hoc Committee on Auction Market Preferred Shares.

The Agreements

Pursuant to the 1940 Act, each Board is required to consider the continuation of the Agreements on an annual basis. In connection with this process, each Board assessed, among other things, the nature, scope and quality of the services provided to its respective Fund by the personnel of BlackRock and its affiliates, including investment management, administrative and shareholder services, oversight of fund accounting and custody, marketing services and assistance in meeting applicable legal and regulatory requirements.

Throughout the year, the Boards, acting directly and through their committees, consider at each of their meetings factors that are relevant to their annual consideration of the renewal of the Agreements, including the services and support provided by BlackRock to the Funds and their shareholders. Among the matters the Boards considered were: (a) investment performance for one-, three- and five-year periods, as applicable, against peer funds, and applicable benchmarks, if any, as well as senior management and portfolio managers’ analysis of the reasons for any outperformance or underperformance against its peers; (b) fees, including advisory and other amounts paid to BlackRock and its affiliates by the Funds for services such as call center and fund accounting; (c) the Funds’ operating expenses; (d) the resources devoted to, and compliance reports relating to, the Funds’ investment objectives, policies and restrictions; (e) the Funds’ compliance with their Code of Ethics and compliance policies and procedures; (f) the nature, cost and character of non-investment management services provided by BlackRock and its affiliates; (g) BlackRock’s and other service providers’ internal controls; (h) BlackRock’s implementation of the proxy voting policies approved by the Boards; (i) execution quality of portfolio transactions; (j) BlackRock’s implementation of the Funds’ valuation and liquidity procedures; and (k) periodic updates on BlackRock’s business.

Board Considerations in Approving the Agreements

The Approval Process: Prior to the April 14, 2009 meeting, each Board requested and received materials specifically relating to the Agreements. Each Board is engaged in an ongoing process with BlackRock to continuously review the nature and scope of the information provided to better assist their deliberations. The materials provided in connection with the April meeting included: (a) information independently compiled and prepared by Lipper, Inc. (“Lipper”) on Fund fees and expenses, and the investment performance of each Fund as compared with a peer group of funds as determined by Lipper (collectively, “Peers”); (b) information on the profitability of the Agreements to BlackRock and a discussion of fall-out benefits to BlackRock and its affiliates and significant shareholders; (c) a general analysis provided by BlackRock concerning investment advisory fees charged to other clients, such as institutional clients and open-end funds, under similar investment mandates, as well as the performance of such other clients; (d) the impact of economies of scale; (e) a summary of aggregate amounts paid by each Fund to BlackRock; and (f) an internal comparison of management fees classified by Lipper, if applicable.

SEMI-ANNUAL REPORT AUGUST 31, 2009 63

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements (continued)

At an in-person meeting held on April 14, 2009, each Board reviewed materials relating to its consideration of the Agreements. As a result of the discussions that occurred during the April 14, 2009 meeting, the Boards presented BlackRock with questions and requests for additional information and BlackRock responded to these requests with additional written information in advance of the May 28 – 29, 2009 Board meeting.

At an in-person meeting held on May 28 – 29, 2009, each Fund’s Board, including the Independent Board Members, unanimously approved the continuation of the Advisory Agreement between the Manager and such Fund and the Sub-Advisory Agreement between such Fund, the Manager and the Sub-Advisor, each for a one-year term ending June 30, 2010. The Boards considered all factors they believed relevant with respect to the Funds, including, among other factors: (a) the nature, extent and quality of the services provided by BlackRock; (b) the investment performance of the Funds and BlackRock portfolio management; (c) the advisory fee and the cost of the services and profits to be realized by BlackRock and certain affiliates from the relationship with the Funds; (d) economies of scale; and (e) other factors.

Each Board also considered other matters it deemed important to the approval process, such as services related to the valuation and pricing of its respective Fund’s portfolio holdings, direct and indirect benefits to BlackRock and its affiliates and significant shareholders from their relationship with such Fund and advice from independent legal counsel with respect to the review process and materials submitted for the Board’s review. The Boards noted the willingness of BlackRock personnel to engage in open, candid discussions with the Boards. The Boards did not identify any particular information as controlling, and each Board Member may have attributed different weights to the various items considered.

A. Nature, Extent and Quality of the Services: Each Board, including its Independent Board Members, reviewed the nature, extent and quality of services provided by BlackRock, including the investment advisory services and the resulting performance of its respective Fund. Throughout the year, each Board compared its respective Fund’s performance to the performance of a comparable group of closed-end funds, and the performance of at least one relevant benchmark, if any. The Boards met with BlackRock’s senior management personnel responsible for investment operations, including the senior investment officers. Each Board also reviewed the materials provided by its respective Fund’s portfolio management team discussing such Fund’s performance and such Fund’s investment objective, strategies and outlook.

Each Board considered, among other factors, the number, education and experience of BlackRock’s investment personnel generally and its respective Fund’s portfolio management team, investments by portfolio managers in the funds they manage, BlackRock’s portfolio trading capabilities, BlackRock’s use of technology, BlackRock’s commitment to compliance and BlackRock’s approach to training and retaining portfolio managers and other research, advisory and management personnel. Each Board also reviewed a general description of BlackRock’s compensation structure with respect to its respective Fund’s portfolio management team and BlackRock’s ability to attract and retain high-quality talent.

In addition to advisory services, each Board considered the quality of the administrative and non-investment advisory services provided to its respective Fund. BlackRock and its affiliates and significant shareholders provide the Funds with certain administrative and other services (in addition to any such services provided to the Funds by third parties) and officers and other personnel as are necessary for the operations of the Funds. In addition to investment advisory services, BlackRock and its affiliates provide the Funds with other services, including: (i) preparing disclosure documents, such as the prospectus and the statement of additional information in connection with the initial public offering and periodic shareholder reports; (ii) preparing communications with analysts to support secondary market trading of the Funds; (iii) assisting with daily accounting and pricing; (iv) preparing periodic filings with regulators and stock exchanges; (v) overseeing and coordinating the activities of other service providers; (vi) organizing Board meetings and preparing the materials for such Board meetings; (vii) providing legal and compliance support; and (viii) performing other administrative functions necessary for the operation of the Funds, such as tax reporting, fulfilling regulatory filing requirements, and call center services. The Boards reviewed the structure and duties of BlackRock’s fund administration, accounting, legal and compliance departments and considered BlackRock’s policies and procedures for assuring compliance with applicable laws and regulations.

B. The Investment Performance of the Funds and BlackRock: Each Board, including its Independent Board Members, also reviewed and considered the performance history of its respective Fund. In preparation for the April 14, 2009 meeting, the Boards were provided with reports, independently prepared by Lipper, which included a comprehensive analysis of each Fund’s performance. The Boards also reviewed a narrative and statistical analysis of the Lipper data that was prepared by BlackRock, which analyzed various factors that affect Lipper’s rankings. In connection with its review, each Board received and reviewed information regarding the investment performance of its respective Fund as compared to a representative group of similar funds as determined by Lipper and to all funds in such Fund’s applicable Lipper category. Each Board was provided with a description of the methodology used by Lipper to select peer funds. Each Board regularly reviews the performance of its respective Fund throughout the year.

64 SEMI-ANNUAL REPORT AUGUST 31, 2009

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements (continued)

The Board of COY noted that although COY underperformed its Peers in at least two of the one-, three- and five-year periods reported, such underper-formance was not greater than 10% of the median return of its Peers for any of the periods. The Board concluded that BlackRock was committed to providing the resources necessary to assist the portfolio managers and to continue improving COY’s performance. Based on its review, the Board generally was satisfied with BlackRock’s efforts to manage COY.

The Board of CYE noted that CYE performed below the median of its Lipper performance universe in the one-, three- and five-year periods reported. The Board and BlackRock reviewed the reasons for CYE’s underperformance during these periods compared with its Peers. The Board was informed that, among other things, exposure to senior bank loans negatively impacted returns. Additionally, CYE’s underweight to BB-rated credits and overweight to CCC-rated credits subtracted from returns as higher quality below investment-grade bonds strongly outperformed their lower quality counterparts.

The Board of DSU noted that DSU performed below the median of its Lipper performance universe in the one-, three- and five-year periods reported. The Board and BlackRock reviewed the reasons for DSU’S underperformance during these periods compared with its Peers. The Board was informed that, among other things, the pressure on bank loan and high yield prices during the period negatively impacted performance.

The Board of ARK noted that ARK performed below the median of its Lipper performance universe in the one-, three- and five-year periods reported. The Board and BlackRock reviewed the reasons for ARK’s underperformance during these periods compared with its Peers. The Board was informed that, among other things, ARK was underweight higher-rated BB-rated securities as a function of its bottom-up security selection process, which impacted performance as higher-rated credits outperformed lower-rated ones by a substantial margin.

For CYE, DSU and ARK, the Board of each respective Fund and BlackRock discussed BlackRock’s commitment to providing the resources necessary to assist the portfolio managers and to improve each such Fund’s performance.

The Board of FRB noted that in general FRB performed better than its Peers in that FRB’s performance was at or above the median of its Lipper Performance Universe in each of the one-year, three-year and since inception periods reported.

C. Consideration of the Advisory Fees and the Cost of the Services and Profits to be realized by BlackRock and its Affiliates from their Relationship with the Funds: Each Board, including its Independent Board Members, reviewed its respective Fund’s contractual advisory fee rates compared with the other funds in its respective Lipper category. Each Board also compared its respective Fund’s total expenses, as well as actual management fees, to those of other comparable funds. Each Board considered the services provided and the fees charged by BlackRock to other types of clients with similar investment mandates, including separately managed institutional accounts.

The Boards received and reviewed statements relating to BlackRock’s financial condition and profitability with respect to the services it provided the Funds. The Boards were also provided with a profitability analysis that detailed the revenues earned and the expenses incurred by BlackRock for services provided to the Funds. The Boards reviewed BlackRock’s profitability with respect to the Funds and other funds the Boards currently oversee for the year ended December 31, 2008 compared to available aggregate profitability data provided for the year ended December 31, 2007. The Boards reviewed BlackRock’s profitability with respect to other fund complexes managed by the Manager and/or its affiliates. The Boards reviewed BlackRock’s assumptions and methodology of allocating expenses in the profitability analysis, noting the inherent limitations in allocating costs among various advisory products. The Boards recognized that profitability may be affected by numerous factors including, among other things, fee waivers by the Manager, the types of funds managed, expense allocations and business mix, and therefore comparability of profitability is somewhat limited.

The Boards noted that, in general, individual fund or product line profitability of other advisors is not publicly available. Nevertheless, to the extent such information is available, the Boards considered BlackRock’s overall operating margin compared to the operating margin for leading investment management firms whose operations include advising closed-end funds, among other product types. The comparison indicated that operating margins for BlackRock with respect to its registered funds are generally consistent with margins earned by similarly situated publicly traded competitors. In addition, the Boards considered, among other things, certain third-party data comparing BlackRock’s operating margin with that of other publicly-traded asset management firms, which concluded that larger asset bases do not, in themselves, translate to higher profit margins.

In addition, the Boards considered the cost of the services provided to the Funds by BlackRock, and BlackRock’s and its affiliates’ profits relating to the management and distribution of the Funds and the other funds advised by BlackRock and its affiliates. As part of their analysis, the Boards reviewed BlackRock’s methodology in allocating its costs to the management of the Funds. The Boards also considered whether BlackRock has the financial resources necessary to attract and retain high-quality investment management personnel to perform its obligations under the Agreements and to continue to provide the high quality of services that is expected by the Boards.

Each Board noted that its respective Fund paid contractual management fees, which do not take into account any expense reimbursement or fee waivers, lower than or equal to the median contractual management fees paid by such Fund’s Peers.

D. Economies of Scale: Each Board, including its Independent Board Members, considered the extent to which economies of scale might be realized as the assets of its respective Fund increase and whether there should be changes in the advisory fee rate or structure in order to enable such Fund to participate in these economies of scale, for example through the use of breakpoints in the advisory fee based upon the assets of such Fund. The Boards considered that the funds in the BlackRock fund complex share some common resources and, as a result, an increase in the overall size of the complex could permit each fund to incur lower expenses than it would otherwise as a stand-alone entity. The Boards also considered BlackRock’s overall operations and its efforts to expand the scale of, and improve the quality of, its operations.

SEMI-ANNUAL REPORT AUGUST 31, 2009 65

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements (concluded)

The Boards noted that most closed-end fund complexes do not have fund level breakpoints because closed-end funds generally do not experience substantial growth after the initial public offering and each fund is managed independently, consistent with its own investment objectives. The Boards noted that only one closed-end fund in the Fund Complex has breakpoints in its fee structure. Information provided by Lipper also revealed that only one closed-end fund complex used a complex-level breakpoint structure.

E. Other Factors: The Boards also took into account other ancillary or “fallout” benefits that BlackRock or its affiliates and significant shareholders may derive from their relationship with the Funds, both tangible and intangible, such as BlackRock’s ability to leverage its investment professionals who manage other portfolios, an increase in BlackRock’s profile in the investment advisory community, and the engagement of BlackRock’s affiliates and significant shareholders as service providers to the Funds, including for administrative and distribution services. The Boards also noted that BlackRock may use third-party research obtained by soft dollars generated by certain mutual fund transactions to assist itself in managing all or a number of its other client accounts.

In connection with their consideration of the Agreements, the Boards also received information regarding BlackRock’s brokerage and soft dollar practices. The Boards received reports from BlackRock, which included information on brokerage commissions and trade execution practices throughout the year.

Conclusion

Each Board, including its Independent Board Members, unanimously approved the continuation of the Advisory Agreement between its respective Fund and the Manager for a one-year term ending June 30, 2010 and the Sub-Advisory Agreement between such Fund, the Manager and Sub-Advisor for a one-year term ending June 30, 2010. Based upon its evaluation of all these factors in their totality, each Board, including its Independent Board Members, was satisfied that the terms of the Agreements were fair and reasonable and in the best interest of its respective Fund and its shareholders. In arriving at a decision to approve the Agreements, each Board did not identify any single factor or group of factors as all-important or controlling, but considered all factors together, and different Board Members may have attributed different weights to the various factors considered. The Independent Board Members were also assisted by the advice of independent legal counsel in making this determination. The contractual fee arrangements for each Fund reflects the results of several years of review by such Fund’s Board Members and predecessor Board Members, and discussions between such Board Members (and predecessor Board Members) and BlackRock. Certain aspects of the arrangements may be the subject of more attention in some years than in others, and the Board Members’ conclusions may be based in part on their consideration of these arrangements in prior years.

Shareholders Who Hold Accounts with Investment Advisors, Banks or Brokerages:

Please contact your financial advisor to enroll. Please note that not all investment advisors, banks or brokerages may offer this service.

Householding

This practice is commonly called “householding” and it is intended to reduce expenses and eliminate duplicate mailings of shareholder documents.
