The Benefits and Risks of Leveraging BlackRock Debt Strategies Fund, Inc. utilizes leveraging through borrowings or issuance of short-term debt securities or shares of Preferred Stock. 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 the Fund on its longer-term portfolio investments. To the extent that the total assets of the Fund (including the assets obtained from leverage) are invested in higher-yielding portfolio investments, the Fund's Common Stock shareholders will benefit from the incremental yield. Leverage creates risks for holders of Common Stock including the likelihood of greater net asset value and market price volatility. In addition, there is the risk that fluctuations in interest rates on borrowings (or in the dividend rates on any Preferred Stock, if the Fund were to issue Preferred Stock) may reduce the Common Stock's yield and negatively impact its net asset value and market price. If the income derived from securities purchased with assets received from leverage exceeds the cost of leverage, the 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, the Fund's net income will be less than if leverage had not been used, and therefore the amount available for distribution to Common Stock shareholders will be reduced.

AUGUST 31, 2007 A Letter to Shareholders Dear Shareholder Financial markets embarked on a wild ride during the August reporting period. Subprime mortgage troubles intensified in the final months of the period, spawning a widespread credit and liquidity crisis that crept into other areas of the market. The U.S. Federal Reserve Board (the Fed) and other countries' central banks stepped in to inject liquidity into the markets and bolster investor confidence. In August, the Fed cut the discount rate, the rate charged to banks to borrow money directly from the Fed, from 6.25% to 5.75%. Another50% cut in the discount rate came on September 18, along with a50% cut in the more widely followed federal funds rate. This brought the target short-term interest rate, which had remained unchanged at 5.25% for over a year, to 4.75%. Although heightened volatility has been a recurring theme throughout the past year, the global economy (excluding the U.S. housing market) remained quite healthy. In general, equity market fundamentals also held firm -- second-quarter corporate earnings exceeded expectations (although future earnings could be at risk if the economy weakens), dividend payouts and share buybacks continued to grow, and valuations remained attractive. These tailwinds generally prevailed over such headwinds as a slowing U.S. economy and troubled housing market, although the more recent credit crunch dampened corporate merger-and-acquisition activity, a key source of strength for equity markets. Stocks recorded their second-worst day of the year in August, yet remained comfortably in the black year-to-date. Meanwhile, mixed economic signals and the credit market debacle made for a volatile backdrop for fixed income, with investors fleeing from bonds associated with the housing and credit markets in favor of higher-quality Treasury issues. As a result, the 10-year Treasury yield, which touched 5.30% in June ( its highest level in five years), fell to 4.54% by period-end, while prices correspondingly rose. Against this backdrop, financial markets posted mixed results for the six- and 12-month periods ended August 31, 2007: Total Returns as of August 31, 2007 6-month 12-month ======================================================================================================== U.S. equities (S&P 500 Index) +5.70% +15.13% -------------------------------------------------------------------------------------------------------- Small cap U.S. equities (Russell 2000 Index) +0.54 +11.36 -------------------------------------------------------------------------------------------------------- International equities (MSCI Europe, Australasia, Far East Index) +5.83 +18.71 -------------------------------------------------------------------------------------------------------- Fixed income (Lehman Brothers U.S. Aggregate Bond Index) +1.54 + 5.26 -------------------------------------------------------------------------------------------------------- Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) -0.57 + 2.30 -------------------------------------------------------------------------------------------------------- High yield bonds (Lehman Brothers U.S. Corporate High Yield 2% Issuer Cap Index) -1.71 + 6.46 -------------------------------------------------------------------------------------------------------- Past performance is no guarantee of future results.

See Notes to Financial Statements. BLACKROCK DEBT STRATEGIES FUND, INC. AUGUST 31, 2007 17 Notes to Financial Statements (Unaudited) 1. Significant Accounting Policies: BlackRock Debt Strategies Fund, Inc. (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a diversified, closed-end management investment company. The Fund's 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. These unaudited financial statements reflect all adjustments, which are, in the opinion of management, necessary to present a fair statement of the results for the interim period. All such adjustments are of a normal, recurring nature. The Fund determines and makes available for publication the net asset value of its Common Stock on a daily basis. The Fund's Common Stock shares are listed on the New York Stock Exchange ("NYSE") under the symbol DSU. (a) Corporate debt obligations -- The Fund invests principally in debt obligations of companies, including floating rate loans made by banks and other financial institutions and both privately and publicly offered corporate bonds and notes. The Fund's investments in loan participation interests involve the risk of insolvency of the financial intermediaries who are parties to the transactions. (b) Valuation of investments -- Floating rate loans are valued in accordance with guidelines established by the Fund's Board of Directors. 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 Loan Pricing Corporation. For the limited number of floating rate loans for which no reliable price quotes are available, such floating rate loans will be valued by Loan Pricing Corporation through the use of pricing matrixes to determine valuations. If the pricing service does not provide a value for floating rate loans, BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc., will value the floating rate loans at fair value, which is intended to approximate market value. Debt securities are traded primarily in the over-the-counter ("OTC") market and are valued at the last available bid price in the OTC market or on the basis of values 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 the Fund under the general direction of the Board of Directors. Such valuations and procedures will be reviewed periodically by the Board of Directors of the Fund. Securities held by the Fund that are traded on stock exchanges or the NASDAQ Global Market are valued at the last sale price or official close price on the exchange on which such securities are traded, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price for long positions, and at the last available asked price for short positions. In cases where securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by or under the authority of the Board of Directors of the Fund. Long positions in securities traded in the OTC market, NASDAQ Capital Market or Bulletin Board are valued at the last available bid price or yield equivalent obtained from one or more dealers or pricing services approved by the Board of Directors of the Fund. Short positions in securities traded in the OTC market are valued at the last available asked price. Portfolio securities that are traded both in the OTC market and on a stock exchange are valued according to the broadest and most representative market. When the Fund writes an option, the amount of the premium received is recorded on the books of the Fund as an asset and an equivalent liability. The amount of the liability is subsequently valued to reflect the current market value of the option written, based on the last sale price in the case of exchange-traded options or, in the case of options traded in the OTC market, the last asked price. Options purchased by the Fund are valued at their last sale price in the case of exchange-traded options or, in the case of options traded in the OTC market, the last bid price. Swap agreements are valued based upon quoted fair valuations received daily by the Fund from a pricing service or counterparty. Other investments, including futures contracts and related options, are stated at market value. Obligations with remaining maturities of 60 days or less are valued at amortized cost unless the Manager believes that this method no longer produces fair valuations. Valuation of other short-term investment vehicles is generally based on the net asset value of the underlying investment vehicle or amortized cost. Repurchase agreements will be valued at cost plus accrued interest. Generally, trading in foreign securities, as well as U.S. government securities, money market instruments and certain fixed income securities, is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. Foreign currency exchange rates will generally be determined as of the close of business on the NYSE. Occasionally, events affecting the values of such securities and such exchange 18 BLACKROCK DEBT STRATEGIES FUND, INC. AUGUST 31, 2007 Notes to Financial Statements (continued) 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 asset value. 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 Fund's Board of Directors or by the Manager using a pricing service and/or procedures approved by the Fund's Board of Directors. (c) Derivative financial instruments -- The 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 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 -- The 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 -- The Fund may write covered call and put options and purchase 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 Swaps -- The 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 Statement 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 instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap agreements. o Forward foreign exchange contracts -- The Fund may enter into forward foreign exchange contracts as a hedge against either specific transactions or portfolio positions. The contract is marked-to-market daily and the change in market value is recorded by the Fund as an unrealized gain or loss. When the contract is closed, the 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. (d) Foreign currency transactions -- Transactions denominated in foreign currencies are recorded at the exchange rate prevailing when recognized. Assets and liabilities denominated in foreign currencies are valued at the exchange rate at the end of the period. Foreign currency transactions are the result of settling (realized) or valuing (unrealized) assets or liabilities expressed in foreign currencies into U.S. dollars. Realized and unrealized gains or losses from investments include the effects of foreign exchange rates on investments. The Fund invests in foreign securities, which may involve a number of risk factors and special considerations not present with investments in securities of U.S. corporations. BLACKROCK DEBT STRATEGIES FUND, INC. AUGUST 31, 2007 19 Notes to Financial Statements (continued) (e) Income taxes -- It is the 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 law, a withholding tax may be imposed on interest, dividends and capital gains at various rates. (f) 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 Fund amortizes all premiums and discounts on debt securities. The Fund earns facility and other fees on loan participation interests. Other fees earned include amendment, consent and prepayment fees. (g) Dividends and distributions -- Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. (h) Securities lending -- The Fund may lend securities to financial institutions that provide cash or securities issued or guaranteed by the U.S. government as collateral, which will be maintained at all times in an amount equal to at least 100% of the current market value of the loaned securities. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. Where the Fund receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Fund typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Fund receives cash collateral, it may invest such collateral and retain the amount earned on such investment, net of any amount rebated to the borrower. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within five business days. The Fund may pay reasonable finder's, lending agent, administrative and custodial fees in connection with its loans. In the event that the borrower defaults on its obligation to return borrowed securities because of insolvency or for any other reason, the Fund could experience delays and costs in gaining access to the collateral. The Fund also could suffer a loss where the value of the collateral falls below the market value of the borrowed securities, in the event of borrower default or in the event of losses on investments made with cash collateral. (i) Recent accounting pronouncements -- Effective August 31, 2007, the Fund implemented Financial Accounting Standards Board ("FASB") Interpretation No. 48, "Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109" ("FIN 48"). 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 investment companies, before being measured and recognized in the financial statements. Management has evaluated the application of FIN 48 to the Fund, and has determined that the adoption of FIN 48 does not have a material impact on the Fund's financial statements. The Fund files U.S. and various state tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund's tax returns remains open for the years ended February 28, 2004 through February 28, 2007. 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 the Fund's financial statements, if any, has not been determined. In addition, in February 2007, FASB issued 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 the Fund's financial statements, if any, has not been determined. 2. Investment Advisory Agreement and Transactions with Affiliates: The Fund has entered into an Investment Advisory Agreement with the Manager. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC Financial Services Group, Inc. are principal owners of BlackRock, Inc. 20 BLACKROCK DEBT STRATEGIES FUND, INC. AUGUST 31, 2007 Notes to Financial Statements (concluded) The Manager is responsible for the management of the Fund's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Fund. For such services, the Fund pays a monthly fee at an annual rate of .60% of the Fund's average daily net assets plus the proceeds of any outstanding borrowings used for leverage. In addition, the Manager has entered into a Sub-Advisory Agreement with BlackRock Financial Management, LLC ("BFM"), an affiliate of the Manager, under which the Manager pays BFM for services it provides a monthly fee at an annual rate that is a percentage of the management fee paid by the Fund to the Manager. The Fund has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated, a wholly owned subsidiary of Merrill Lynch, or its affiliates. Pursuant to that order, the Fund has retained BlackRock Investment Management, LLC ("BIM"), an affiliate of the Manager, as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. BIM may, on behalf of the Fund, invest cash collateral received by the Fund for such loans, among other things, in a private investment company managed by the Manager or in registered money market funds advised by the Manager or its affiliates. For the six months ended August 31, 2007, the Fund reimbursed the Manager $7,641 for certain accounting services. Certain officers and/or directors of the Fund are officers and/or directors of BlackRock, Inc. or its affiliates. 3. Investments: Purchases and sales ( including paydowns) of investments, excluding short-term securities, for the six months ended August 31, 2007 were $313,008,645 and $406,966,430, respectively. 4. Capital Share Transactions: The Fund is authorized to issue 200,000,000 shares of capital stock, par value $.10 per share, all of which were initially classified as Common Stock. The Board of Directors is authorized, however, to classify and reclassify any unissued shares of capital stock without approval of the holders of Common Stock. Shares issued and outstanding during the six months ended August 31, 2007 and the year ended February 28, 2007 increased by 227,222 and 579,550, respectively, as a result of dividend reinvestment. 5. Unfunded Loan Commitments: As of August 31, 2007, the Fund had unfunded loan commitments of approximately $3,455,000, which would be extended at the option of the borrower, pursuant to the following loan agreements: (in Thousands) -------------------------------------------------------------------------------- Value of Unfunded Underlying Borrower Commitment Loan -------------------------------------------------------------------------------- Big West Oil ......................................... $ 963 $ 909 Las Vegas Sands ...................................... $ 800 $ 760 MEG Energy Corp. ..................................... $ 1,250 $ 1,196 NG Wireless .......................................... $ 140 $ 138 Univision Communications, Inc. ....................... $ 302 $ 279 -------------------------------------------------------------------------------- 6. Short-Term Borrowings: On May 16, 2007, the Fund renewed its revolving credit and security agreement funded by 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 has a maximum limit of $370,000,000. Under the Citicorp program, the conduits will fund advances to the Fund through the issuance of highly rated commercial paper. As security for its obligations to the Lenders under the revolving securitization facility, the Fund has granted a security interest in substantially all of its assets to and in favor of the Lenders. The interest rate on the Fund's borrowings is based on the interest rate carried by the commercial paper plus a program fee. The Fund pays additional borrowing costs including a backstop commitment fee. The weighted average annual interest rate was 5.62% and the average borrowing was approximately $302,039,000 for the six months ended August 31, 2007. 7. Capital Loss Carryforward: On February 28, 2007, the Fund had a net capital loss carry-forward of $310,688,248, of which $51,234,056 expires in 2008, $21,442,332 expires in 2009, $90,564,493 expires in 2010, $85,285,305 expires in 2011, $17,223,475 expires in 2012, $21,126,025 expires in 2013, $20,233,987 expires in 2014 and $3,578,575 expires in 2015.
