The Benefits and Risks of Leveraging BlackRock Corporate High Yield Fund III, 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. Since 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 are the beneficiaries of 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. 2 BLACKROCK CORPORATE HIGH YIELD FUND III, INC. MAY 31, 2007 A Letter to Shareholders Dear Shareholder The 12 months from May 2006 to May 2007 took global equities on an extraordinary ride. A sharp correction at the start, the first in almost four years, gave way to strength in the latter half of 2006 and early 2007. This rally was interrupted by another set-back at the end of February, before markets resumed their upward march through May 31. Ultimately, the tailwinds of a generally favorable global economic backdrop, tame inflation, relatively low interest rates, still positive earnings growth and attractive valuations prevailed over the headwinds of a weakening U.S. economy, slowing housing market, escalating geopolitical concerns and high energy prices. In fact, both the Dow Jones Industrial Average and the Standard & Poor's 500 Index touched new record highs following the most recent correction. Mixed economic signals led to volatile behavior in fixed income markets as well. However, from the beginning of 2007 through May 31, short-term bond yields generally fell while longer-term yields increased. This resulted in some re-steepening of the yield curve, which had been flat to inverted throughout 2006. On a year-over-year basis, yields on 30-year Treasury bonds fell 20 basis points (.20%) and 10-year yields fell 22 basis points, while bond prices correspondingly rose. Meanwhile, the Federal Reserve Board (the Fed) has left the federal funds rate at 5.25% since first pausing in August 2006. While first-quarter gross domestic product growth of 0.6% represented the slowest rate of expansion since 2002, the Fed reiterated its view that inflation, not a slowing economy, remains its primary concern. Many observers interpreted the Fed's reaction to mean that the economy has hit its low and is bound for renewed strength, therefore reducing the likelihood of an interest rate cut in the near future. Against this backdrop, most major market indexes posted positive returns for the annual and semi-annual reporting periods ended May 31, 2007, with equities exhibiting particular strength: Total Returns as of May 31, 2007 6-month 12-month =============================================================================================================== U.S. equities (Standard & Poor's 500 Index) +10.29% +22.79% --------------------------------------------------------------------------------------------------------------- Small cap U.S. equities (Russell 2000 Index) + 8.39 +18.92 --------------------------------------------------------------------------------------------------------------- International equities (MSCI Europe, Australasia, Far East Index) +14.08 +26.84 --------------------------------------------------------------------------------------------------------------- Fixed income (Lehman Brothers Aggregate Bond Index) + 0.69 + 6.66 --------------------------------------------------------------------------------------------------------------- Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) + 0.30 + 4.84 --------------------------------------------------------------------------------------------------------------- High yield bonds (Lehman Brothers U.S. Corporate High Yield 2% Issuer Cap Index) + 6.02 +12.64 --------------------------------------------------------------------------------------------------------------- We expect market volatility to linger throughout the remainder of 2007. As you navigate the uncertainties, we encourage you to review your investment goals with your financial professional and to make portfolio changes, as needed. For more insight, we invite you to view "What's Ahead in 2007: An Investment Perspective" and "Are You Prepared for Volatility?" at www.blackrock.com/funds. We thank you for entrusting BlackRock with your investment assets, and we look forward to continuing to serve you in the months and years ahead. Sincerely, /s/ Robert C. Doll, Jr. Robert C. Doll, Jr. Fund President and Director BLACKROCK CORPORATE HIGH YIELD FUND III, INC. MAY 31, 2007 3 A Discussion With Your Fund's Portfolio Managers The Fund outperformed the Credit Suisse High Yield Index and its comparable Lipper category average for the fiscal year. How did the Fund perform during the fiscal year in light of the existing market conditions? For the 12-month period ended May 31, 2007, the Common Stock of BlackRock Corporate High Yield Fund III, Inc. had net annualized yields of 7.52% and 7.92%, based on a year-end per share net asset value of $8.99 and a per share market price of $8.53, respectively, and $.676 per share income dividends. For the same period, the total investment return on the Fund's Common Stock was +15.51%, based on a change in per share net asset value from $8.46 to $8.99, and assuming reinvestment of all distributions. The high yield bond market, as measured by the Credit Suisse High Yield Index, returned +13.21% for the 12-month period, while the Fund's comparable Lipper category of High Current Yield Funds (Leveraged) had an average return of +14.61%. (Funds in this Lipper category aim for relatively high current yield from investment in fixed income securities, have no quality or maturity restrictions, and tend to invest in lower-grade debt issues.) For the six-month period ended May 31, 2007, the total investment return on the Fund's Common Stock was +8.68%, based on a change in per share net asset value from $8.61 to $8.99, and assuming reinvestment of all distributions. The Credit Suisse High Yield Index returned +6.53% for the period, while the Lipper High Current Yield Funds (Leveraged) category had an average return of +7.59%. For a description of the Fund's total investment return based on a change in the per share market value of the Fund's Common Stock (as measured by the trading price of the Fund's shares on the New York Stock Exchange), and assuming reinvestment of distributions, please refer to the Financial Highlights section of this report. As a closed-end fund, the Fund's shares may trade in the secondary market at a premium or a discount to the Fund's net asset value. As a result, total investment returns based on changes in the market value of the Fund's Common Stock can vary significantly from total investment returns based on changes in the Fund's net asset value. The high yield market moved upward over the past 12 months, although it did encounter weakness early on in June 2006. The market managed to post positive returns in each of the next 11 months, aided by the continuation of historically low default rates and relatively low new-issue supply. Additionally, the high yield market continued to experience significant inflows as low overall volatility and strong U.S. equity market returns motivated investors to seek higher-yielding assets. As measured by the Credit Suisse High Yield Index, the yield spreads of high yield bonds versus those of 10-year U.S. Treasury securities decreased from 329 basis points (3.29%) on May 31, 2006, to 238 basis points at May 31, 2007. High yield securities and the Fund significantly outperformed U.S. Treasury issues, which returned +5.97% for the 12-month period, as measured by the Merrill Lynch 10-Year U.S. Treasury Securities Index. Accordingly, the higher-quality sector of the high yield market, which is more closely correlated with Treasury issues, lagged during the period while lower-quality issues outperformed. Against this backdrop, the Fund's exposure to lower-quality credits benefited performance. In the latter half of the fiscal year, after a new management team assumed responsibility for the portfolio, its overweight position in issues rated B and CCC was beneficial to performance. Conversely, an underweight exposure to BB-rated issues detracted from performance, as all segments of the high yield market performed well. Also in the latter six months, the Fund's overweight positions in the media (non-cable), technology, aerospace/defense, consumer service and chemical sectors were the strongest positive contributors to performance. Underweight positions in automotives, supermarkets and home construction were the biggest detractors. What changes were made to the portfolio during the period? A new management team assumed responsibility for the day-to-day management of the Fund's portfolio in October 2006 and implemented its longstanding strategy of investing in securities of higher-quality companies with good pricing power and strong fundamentals. Having said that, the management team did increase allocations to certain lower-quality credit tiers, establishing overweight positions in B-rated and CCC-rated credits in an effort to capitalize on positive returns being generated by these segments of the high yield market. As mentioned earlier, the increased emphasis on lower-quality issues benefited performance in the second half of the fiscal year. 4 BLACKROCK CORPORATE HIGH YIELD FUND III, INC. MAY 31, 2007 From a sector perspective, we moved the portfolio to overweight positions versus the benchmark in the media (non-cable), gaming and paper industries. We maintained the portfolio's underweight exposure to electric utilities, media (cable), supermarkets and lodging. The Fund's leverage position earned an incremental yield on the investments we made with the borrowed funds. For the year ended May 31, 2007, the average amount borrowed was $134.7 million, and the daily weighted average interest rate was 5.52%. While leveraging will enhance the Fund's total return in a strong market, the converse also is true in a weak market. (For a more complete discussion of the benefits and risks of leveraging, see page 2 of this report to shareholders.) How would you characterize the Fund's position at the close of the period? Volatility picked up somewhat in the second quarter of 2007, resulting in an investor flight to quality. However, fundamental and technical valuations remained favorable for the high yield market, with default rates below 1% and a new-issue calendar that was just beginning to satisfy the high yield investor. The Fund had an average credit rating of B at the end of the period, consistent with the rating of the Credit Suisse High Yield Index and unchanged from the beginning of the period. At May 31, 2007, 92.7% of the Fund's net assets was invested in high yield bonds. The portfolio was overweight relative to the benchmark in the media (non-cable), retail and aerospace/defense sectors. The Fund's primary underweights were in the information technology, automotive, financials and housing sectors. Floating rate securities, including bank loans, accounted for 2.4% of non-cash investments at period-end. We retain our emphasis on investing in securities of higher-quality companies with good pricing power and strong fundamentals. Going forward, we will continue to focus on increasing the Fund's net asset value with the intention of producing a competitive total return for shareholders. The turmoil in the subprime mortgage market in the first half of 2007 has not had a direct effect on Fund performance, but we maintain the portfolio's underweight exposure to securities issued by homebuilders.

MAY 31, 2007 17 Notes to Financial Statements 1. Significant Accounting Policies: On September 29, 2006, Corporate High Yield Fund III, Inc. was renamed BlackRock Corporate High Yield Fund III, Inc. (the "Fund"). 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. 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 CYE. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments -- Debt securities are traded primarily in the over-the-counter ("OTC") markets and are valued at the last available bid price in the OTC market or on the basis of values obtained by a pricing service. Floating rate loan interests are valued at the mean between the last available bid and asked prices from one or more brokers or dealers as obtained by a pricing service. Pricing services use valuation matrixes that incorporate both dealer-supplied valuations and valuation models. The procedures of the pricing service and its valuations are reviewed by the officers of 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. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their closing prices as of the close of such exchanges. Options written or purchased are valued at the last sale price in the case of exchange-traded options. Options traded in the OTC market are valued at the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued based upon quoted fair valuations received daily by the Fund from a pricing service or counterparty. Valuation of short-term investment vehicles is generally based on the net asset value of the underlying investment vehicle or amortized cost. Repurchase agreements are valued at cost plus accrued interest. Investments in open-end investment companies are valued at their net asset value each business day. Securities and other assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Directors of the Fund. Equity 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, 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 equity 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 traded in the OTC markets, NASDAQ Capital Market or Bulletin Board are valued at the last available bid price obtained from one or more dealers or pricing services approved by the Board of Directors of the Fund. Short positions traded in the OTC markets are valued at the last available asked price. Portfolio securities that are traded both in the OTC markets and on a stock exchange are valued according to the broadest and most representative market. Generally, trading in foreign 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 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 BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc., using a pricing service and/or procedures approved by the Fund's Board of Directors. (b) 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 due to an unfavorable change in the price of the underlying security or if the counterparty does not perform under the contract. o Options -- The Fund may write 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 18 BLACKROCK CORPORATE HIGH YIELD FUND III, INC. MAY 31, 2007 Notes to Financial Statements (continued) 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 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 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. (c) 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 to 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. (d) 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. (e) Security transactions and investment income -- Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Interest income is recognized on the accrual basis. The Fund amortizes all premiums and discounts on debt securities. (f) Dividends and distributions -- Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. (g) 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 BLACKROCK CORPORATE HIGH YIELD FUND III, INC. MAY 31, 2007 19 Notes to Financial Statements (continued) 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. (h) Recent accounting pronouncements -- In July 2006, the Financial Accounting Standards Board released FASB Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes." FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in financial statements. FIN 48 requires the evaluation of tax positions taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the more-likely-than-not threshold would be booked as a tax expense in the current year and recognized as: a liability for unrecognized tax benefits; a reduction of an income tax refund receivable; a reduction of deferred tax asset; an increase in deferred tax liability; or a combination thereof. Adoption of FIN 48 is required for the last net asset value calculation in the first required financial statement reporting period for fiscal years beginning after December 15, 2006. The impact on the Fund's financial statements, if any, is currently being assessed. In September 2006, Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"), was issued and is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. At this time, management is evaluating the implications of FAS 157 and its impact on 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"), which 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. (i) Reclassification -- U.S. generally accepted accounting principles require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. Accordingly, during the current year, $456,158 has been reclassified between accumulated net realized capital losses and undistributed net investment income as a result of permanent differences attributable to amortization methods of premiums and discounts on fixed income securities and accounting for swap agreements. This reclassification has no effect on net assets or net asset values per share. 2. Investment Advisory Agreement and Transactions with Affiliates: On September 29, 2006, Merrill Lynch & Co., Inc. ("Merrill Lynch") combined Merrill Lynch's investment management business, Merrill Lynch Investment Managers, L.P. ("MLIM"), and its affiliates, including Fund Asset Management, L.P. ("FAM"), with BlackRock, Inc. to create a new independent company. Merrill Lynch has a 49.8% economic interest and a 45% voting interest in the combined company and The PNC Financial Services Group, Inc., has approximately a 34% economic and voting interest. The new company operates under the BlackRock name and is governed by a board of directors with a majority of independent members. On August 15, 2006, shareholders of the Fund approved a new Investment Advisory Agreement with BlackRock Advisors, Inc. BlackRock Advisors, Inc. was reorganized into a limited liability company and renamed BlackRock Advisors, LLC. The new Investment Advisory Agreement between the Fund and the Manager became effective on September 29, 2006. Prior to September 29, 2006, FAM was the manager. The general partner of FAM is an indirect, wholly owned subsidiary of Merrill Lynch, which is the limited partner. 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 principal borrowed. In addition, the Manager has entered into a sub-advisory agreement with BlackRock Financial Management, Inc., an affiliate of the Manager, under which the Manager pays the Sub-Adviser for services it provides a fee that is a percentage of the management fee paid by the Fund to the Manager. Prior to September 29, 2006, FAM had a 20 BLACKROCK CORPORATE HIGH YIELD FUND III, INC. MAY 31, 2007 Notes to Financial Statements (concluded) Sub-Advisory Agreement with Merrill Lynch Asset Management U.K. Limited ("MLAM U.K."), an affiliate of FAM. 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 ("MLPF&S"), 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. Prior to September 29, 2006, BIM was organized as Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of FAM, and MLIM, LLC was the securities lending agent. 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. In addition, MLPF&S received $625 in commissions on the execution of portfolio security transactions for the Fund for the year ended May 31, 2007. For the year ended May 31, 2007, the Fund reimbursed FAM and the Manager $2,457 and $4,068, respectively, for certain accounting services. Prior to September 29, 2006, certain officers and/or directors of the Fund were officers and/or directors of FAM, MLIM, PSI, MLAM U.K., Merrill Lynch, and/or MLIM, LLC. Commencing September 29, 2006, 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 year ended May 31, 2007 were $271,135,381 and $282,885,409, respectively. 4. Capital Share Transactions: The Fund is authorized to issue 200,000,000 shares of capital stock, par value $.10, 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 year ended May 31, 2007 remained constant. Shares issued and outstanding during the year ended May 31, 2006 increased by 6,358, as a result of dividend reinvestment. 5. Short-Term Borrowings: On May 18, 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 $160,000,000. 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. For the year ended May 31, 2007, the average amount borrowed was approximately $134,704,000, and the daily weighted average interest rate was 5.52%. 6. Distributions to Shareholders: The Fund paid an ordinary income dividend in the amount of $.060000 per share on June 15, 2007 to shareholders of record on June 29, 2007. The tax character of distributions paid during the fiscal years ended May 31, 2007 and May 31, 2006 was as follows: -------------------------------------------------------------------------------- 5/31/2007 5/31/2006 -------------------------------------------------------------------------------- Distributions paid from: Ordinary income ................................ $25,076,686 $27,760,574 -------------------------- Total taxable distributions ...................... $25,076,686 $27,760,574 ========================== As of May 31, 2007, the components of accumulated losses on a tax basis were as follows: ----------------------------------------------------------------------------- Undistributed ordinary income -- net ....................... $ 5,188,275 Undistributed long-term capital gains -- net ............... -- Total undistributed earnings -- net ........................ 5,188,275 Capital loss carryforward .................................. (226,665,964)* Unrealized gains -- net .................................... 12,430,914** Total accumulated losses -- net ............................ $(209,046,775) * On May 31, 2007, the Fund had a net capital loss carryforward of $226,665,964, of which $18,095,581 expires in 2008, $34,200,029 expires in 2009, $52,918,036 expires in 2010, $119,513,437 expires in 2011 and $1,938,881 expires in 2012. This amount will be available to offset like amounts of any future taxable gains. ** The difference between book-basis and tax-basis net unrealized gains is attributable primarily to the tax deferral of losses on wash sales, the difference between book and tax amortization methods for premiums and discounts on fixed income securities, the book/tax differences in the accrual of income on securities in default and the accounting for swap agreements. BLACKROCK CORPORATE HIGH YIELD FUND III, INC. MAY 31, 2007 21 Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors of BlackRock Corporate High Yield Fund III, Inc.: We have audited the accompanying statement of assets, liabilities and capital, including the schedule of investments, of BlackRock Corporate High Yield Fund III, Inc. (formerly Corporate High Yield Fund III, Inc.) as of May 31, 2007, and the related statements of operations and cash flows for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of May 31, 2007, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of BlackRock Corporate High Yield Fund III, Inc. as of May 31, 2007, the results of its operations and its cash flows for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. Deloitte & Touche LLP Princeton, New Jersey July 25, 2007 Fund Certification (Unaudited) In September 2006, the Fund filed its Chief Executive Officer Certification with the New York Stock Exchange pursuant to Section 303A.12(a) of the New York Stock Exchange Corporate Governance Listing Standards.

MAY 31, 2007 Automatic Dividend Reinvestment Plan How the Plan Works -- The Fund offers a Dividend Reinvestment Plan (the "Plan") under which income and capital gains dividends paid by the Fund are automatically reinvested in additional shares of Common Stock of the Fund. The Plan is administered on behalf of the shareholders by Computershare Trust Company, N.A. (the "Plan Agent"). Under the Plan, whenever the Fund declares a dividend, participants in the Plan will receive the equivalent in shares of Common Stock of the Fund. The Plan Agent will acquire the shares for the participant's account either (i) through receipt of additional unissued but authorized shares of the Fund ("newly issued shares") or (ii) by purchase of outstanding shares of Common Stock on the open market on the New York Stock Exchange or elsewhere. If, on the dividend payment date, the Fund's net asset value per share is equal to or less than the market price per share plus estimated brokerage commissions (a condition often referred to as a "market premium"), the Plan Agent will invest the dividend amount in newly issued shares. If the Fund's net asset value per share is greater than the market price per share (a condition often referred to as a "market discount"), the Plan Agent will invest the dividend amount by purchasing on the open market additional shares. If the Plan Agent is unable to invest the full dividend amount in open market purchases, or if the market discount shifts to a market premium during the purchase period, the Plan Agent will invest any uninvested portion in newly issued shares. The shares acquired are credited to each shareholder's account. The amount credited is determined by dividing the dollar amount of the dividend by either (i) when the shares are newly issued, the net asset value per share on the date the shares are issued or (ii) when shares are purchased in the open market, the average purchase price per share. Participation in the Plan -- Participation in the Plan is automatic, that is, a shareholder is automatically enrolled in the Plan when he or she purchases shares of Common Stock of the Fund unless the shareholder specifically elects not to participate in the Plan. Shareholders who elect not to participate will receive all dividend distributions in cash. Shareholders who do not wish to participate in the Plan must advise the Plan Agent in writing (at the address set forth below) that they elect not to participate in the Plan. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by writing to the Plan Agent. Benefits of the Plan -- The Plan provides an easy, convenient way for shareholders to make additional, regular investments in the Fund. The Plan promotes a long-term strategy of investing at a lower cost. All shares acquired pursuant to the Plan receive voting rights. In addition, if the market price plus commissions of the Fund's shares is above the net asset value, participants in the Plan will receive shares of the Fund for less than they could otherwise purchase them and with a cash value greater than the value of any cash distribution they would have received. However, there may not be enough shares available in the market to make distributions in shares at prices below the net asset value. Also, since the Fund does not redeem shares, the price on resale may be more or less than the net asset value. Plan Fees -- There are no enrollment fees or brokerage fees for participating in the Plan. The Plan Agent's service fees for handling the reinvestment of distributions are paid for by the Fund. However, brokerage commissions may be incurred when the Fund purchases shares on the open market and shareholders will pay a pro rata share of any such commissions. Tax Implications -- The automatic reinvestment of dividends and distributions will not relieve participants of any federal, state or local income tax that may be payable (or required to be withheld) on such dividends. Therefore, income and capital gains may still be realized even though shareholders do not receive cash. The value of shares acquired pursuant to the Plan will generally be excluded from gross income to the extent that the cash amount reinvested would be excluded from gross income. If, when the Fund's shares are trading at a market premium, the Fund issues shares pursuant to the Plan that have a greater fair market value than the amount of cash reinvested, it is possible that all or a portion of the discount from the market value (which may not exceed 5% of the fair market value of the Fund's shares) could be viewed as a taxable distribution. If the discount is viewed as a taxable distribution, it is also possible that the taxable character of this discount would be allocable to all the shareholders, including shareholders who do not participate in the Plan. Thus, shareholders who do not participate in the Plan might be required to report as ordinary income a portion of their distributions equal to their allocable share of the discount.

MAY 31, 2007 27 BlackRock Corporate High Yield Fund III, Inc. seeks to provide shareholders with current income by investing primarily in a diversified portfolio of fixed income securities that are rated in the lower rating categories of the established rating services (Ba or lower by Moody's Investors Service, Inc. or BB or lower by Standard & Poor's Corporation) or are unrated securities of comparable quality. This report, including the financial information herein, is transmitted to shareholders of BlackRock Corporate High Yield Fund III, Inc. for their information. It is not a prospectus. The Fund has leveraged its Common Stock to provide Common Stock shareholders with a potentially higher rate of return. Leverage creates risk for Common Stock shareholders, including the likelihood of greater volatility of net asset value and market price of Common Stock shares, and the risk that fluctuations in short-term interest rates may reduce the Common Stock's yield. Past performance results shown in this report should not be considered a representation of future performance. Statements and other information herein are as dated and are subject to change.

Item 7 - Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies - Proxy Voting Policies and Procedures Applicable to the Fund Each Fund's Board of Directors has delegated to the Manager authority to vote all proxies relating to the Fund's portfolio securities. The Manager has adopted policies and procedures (the "Proxy Voting Procedures") with respect to the voting of proxies related to the portfolio securities held in the account of one or more of its clients, including a Fund. Pursuant to these Proxy Voting Procedures, the Manager's primary objective when voting proxies is to make proxy voting decisions solely in the best interests of each Fund and its shareholders, and to act in a manner that the Manager believes is most likely to enhance the economic value of the securities held by the Fund. The Proxy Voting Procedures are designed to ensure that the Manager considers the interests of its clients, including each Fund, and not the interests of the Manager, when voting proxies and that real (or perceived) material conflicts that may arise between the Manager's interest and those of the Manager's clients are properly addressed and resolved. In order to implement the Proxy Voting Procedures, the Manager has formed a Proxy Voting Committee (the "Committee"). The Committee, which is a subcommittee of the Manager's Equity Investment Policy Oversight Committee ("EIPOC"), is comprised of a senior member of the Manager's equity management group who is also a member of EIPOC, one or more other senior investment professionals appointed by EIPOC, portfolio managers and investment analysts appointed by EIPOC and any other personnel EIPOC deems appropriate. The Committee will also include two non-voting representatives from the Manager's Legal Department appointed by the Manager's General Counsel. The Committee's membership shall be limited to full-time employees of the Manager. No person with any investment banking, trading, retail brokerage or research responsibilities for the Manager's affiliates may serve as a member of the Committee or participate in its decision making (except to the extent such person is asked by the Committee to present information to the Committee on the same basis as other interested knowledgeable parties not affiliated with the Manager might be asked to do so). The Committee determines how to vote the proxies of all clients, including a Fund, that have delegated proxy voting authority to the Manager and seeks to ensure that all votes are consistent with the best interests of those clients and are free from unwarranted and inappropriate influences. The Committee establishes general proxy voting policies for the Manager and is responsible for determining how those policies are applied to specific proxy votes, in light of each issuer's unique structure, management, strategic options and, in certain circumstances, probable economic and other anticipated consequences of alternate actions. In so doing, the Committee may determine to vote a particular proxy in a manner contrary to its generally stated policies. In addition, the Committee will be responsible for ensuring that all reporting and recordkeeping requirements related to proxy voting are fulfilled. The Committee may determine that the subject matter of a recurring proxy issue is not suitable for general voting policies and requires a case-by-case determination. In such cases, the Committee may elect not to adopt a specific voting policy applicable to that issue. The Manager believes that certain proxy voting issues require investment analysis - such as approval of mergers and other significant corporate transactions - akin to investment decisions, and are, therefore, not suitable for general guidelines. The Committee may elect to adopt a common position for the Manager on certain proxy votes that are akin to investment decisions, or determine to permit the portfolio manager to make individual decisions on how best to maximize economic value for a Fund (similar to normal buy/sell investment decisions made by such portfolio managers). While it is expected that the Manager will generally seek to vote proxies over which the Manager exercises voting authority in a uniform manner for all the Manager's clients, the Committee, in conjunction with a Fund's portfolio manager, may determine that the Fund's specific circumstances require that its proxies be voted differently. To assist the Manager in voting proxies, the Committee has retained Institutional Shareholder Services ("ISS"). ISS is an independent adviser that specializes in providing a variety of fiduciary-level proxy-related services to institutional investment managers, plan sponsors, custodians, consultants, and other institutional investors. The services provided to the Manager by ISS include in-depth research, voting recommendations (although the Manager is not obligated to follow such recommendations), vote execution, and recordkeeping. ISS will also assist the Fund in fulfilling its reporting and recordkeeping obligations under the Investment Company Act. The Manager's Proxy Voting Procedures also address special circumstances that can arise in connection with proxy voting. For instance, under the Proxy Voting Procedures, the Manager generally will not seek to vote proxies related to portfolio securities that are on loan, although it may do so under certain circumstances. In addition, the Manager will vote proxies related to securities of foreign issuers only on a best efforts basis and may elect not to vote at all in certain countries where the Committee determines that the costs associated with voting generally outweigh the benefits. The Committee may at any time override these general policies if it determines that such action is in the best interests of a Fund. From time to time, the Manager may be required to vote proxies in respect of an issuer where an affiliate of the Manager (each, an "Affiliate"), or a money management or other client of the Manager, including investment companies for which the Manager provides investment advisory, administrative and/or other services (each, a "Client"), is involved. The Proxy Voting Procedures and the Manager's adherence to those procedures are designed to address such conflicts of interest. The Committee intends to strictly adhere to the Proxy Voting Procedures in all proxy matters, including matters involving Affiliates and Clients. If, however, an issue representing a non-routine matter that is material to an Affiliate or a widely known Client is involved such that the Committee does not reasonably believe it is able to follow its guidelines (or if the particular proxy matter is not addressed by the guidelines) and vote impartially, the Committee may, in its discretion for the purposes of ensuring that an independent determination is reached, retain an independent fiduciary to advise the Committee on how to vote or to cast votes on behalf of the Manager's clients. In the event that the Committee determines not to retain an independent fiduciary, or it does not follow the advice of such an independent fiduciary, the Committee may pass the voting power to a subcommittee, appointed by EIPOC (with advice from the Secretary of the Committee), consisting solely of Committee members selected by EIPOC. EIPOC shall appoint to the subcommittee, where appropriate, only persons whose job responsibilities do not include contact with the Client and whose job evaluations would not be affected by the Manager's relationship with the Client (or failure to retain such relationship). The subcommittee shall determine whether and how to vote all proxies on behalf of the Manager's clients or, if the proxy matter is, in their judgment, akin to an investment decision, to defer to the applicable portfolio managers, provided that, if the subcommittee determines to alter the Manager's normal voting guidelines or, on matters where the Manager's policy is case-by-case, does not follow the voting recommendation of any proxy voting service or other independent fiduciary that may be retained to provide research or advice to the Manager on that matter, no proxies relating to the Client may be voted unless the Secretary, or in the Secretary's absence, the Assistant Secretary of the Committee concurs that the subcommittee's determination is consistent with the Manager's fiduciary duties. In addition to the general principles outlined above, the Manager has adopted voting guidelines with respect to certain recurring proxy issues that are not expected to involve unusual circumstances. These policies are guidelines only, and the Manager may elect to vote differently from the recommendation set forth in a voting guideline if the Committee determines that it is in a Fund's best interest to do so. In addition, the guidelines may be reviewed at any time upon the request of a Committee member and may be amended or deleted upon the vote of a majority of Committee members present at a Committee meeting at which there is a quorum. The Manager has adopted specific voting guidelines with respect to the following proxy issues: o Proposals related to the composition of the board of directors of issuers other than investment companies. As a general matter, the Committee believes that a company's board of directors (rather than shareholders) is most likely to have access to important, nonpublic information regarding a company's business and prospects, and is, therefore, best-positioned to set corporate policy and oversee management. The Committee, therefore, believes that the foundation of good corporate governance is the election of qualified, independent corporate directors who are likely to diligently represent the interests of shareholders and oversee management of the corporation in a manner that will seek to maximize shareholder value over time. In individual cases, the Committee may look at a nominee's number of other directorships, history of representing shareholder interests as a director of other companies or other factors, to the extent the Committee deems relevant. o Proposals related to the selection of an issuer's independent auditors. As a general matter, the Committee believes that corporate auditors have a responsibility to represent the interests of shareholders and provide an independent view on the propriety of financial reporting decisions of corporate management. While the Committee will generally defer to a corporation's choice of auditor, in individual cases, the Committee may look at an auditors' history of representing shareholder interests as auditor of other companies, to the extent the Committee deems relevant. o Proposals related to management compensation and employee benefits. As a general matter, the Committee favors disclosure of an issuer's compensation and benefit policies and opposes excessive compensation, but believes that compensation matters are normally best determined by an issuer's board of directors, rather than shareholders. Proposals to "micro-manage" an issuer's compensation practices or to set arbitrary restrictions on compensation or benefits will, therefore, generally not be supported. o Proposals related to requests, principally from management, for approval of amendments that would alter an issuer's capital structure. As a general matter, the Committee will support requests that enhance the rights of common shareholders and oppose requests that appear to be unreasonably dilutive. o Proposals related to requests for approval of amendments to an issuer's charter or by-laws. As a general matter, the Committee opposes poison pill provisions. o Routine proposals related to requests regarding the formalities of corporate meetings. o Proposals related to proxy issues associated solely with holdings of investment company shares. As with other types of companies, the Committee believes that a fund's board of directors (rather than its shareholders) is best positioned to set fund policy and oversee management. However, the Committee opposes granting boards of directors authority over certain matters, such as changes to a fund's investment objective, which the Investment Company Act envisions will be approved directly by shareholders. o Proposals related to limiting corporate conduct in some manner that relates to the shareholder's environmental or social concerns. The Committee generally believes that annual shareholder meetings are inappropriate forums for discussion of larger social issues, and opposes shareholder resolutions "micromanaging" corporate conduct or requesting release of information that would not help a shareholder evaluate an investment in the corporation as an economic matter. While the Committee is generally supportive of proposals to require corporate disclosure of matters that seem relevant and material to the economic interests of shareholders, the Committee is generally not supportive of proposals to require disclosure of corporate matters for other purposes.

BlackRock has adopted policies and procedures that address the allocation of investment opportunities, execution of portfolio transactions, personal trading by employees and other potential conflicts of interest that are designed to ensure that all client accounts are treated equitably over time. Nevertheless, BlackRock furnishes investment management and advisory services to numerous clients in addition to the Fund, and BlackRock may, consistent with applicable law, make investment recommendations to other clients or accounts (including accounts which are hedge funds or have performance or higher fees paid to BlackRock, or in which portfolio managers have a personal interest in the receipt of such fees), which may be the same as or different from those made to the Fund. In addition, BlackRock, its affiliates and any officer, director, stockholder or employee may or may not have an interest in the securities whose purchase and sale BlackRock recommends to the Fund. BlackRock, or any of its affiliates, or any officer, director, stockholder, employee or any member of their families may take different actions than those recommended to the Fund by BlackRock with respect to the same securities. Moreover, BlackRock may refrain from rendering any advice or services concerning securities of companies of which any of BlackRock's (or its affiliates') officers, directors or employees are directors or officers, or companies as to which BlackRock or any of its affiliates or the officers, directors and employees of any of them has any substantial economic interest or possesses material non-public information. Each portfolio manager also may manage accounts whose investment strategies may at times be opposed to the strategy utilized for the Fund. In this connection, it should be noted that certain portfolio managers currently manage certain accounts that are subject to performance fees. In addition, certain portfolio managers assist in managing certain hedge funds and may be entitled to receive a portion of any incentive fees earned on such funds and a portion of such incentive fees may be voluntarily or involuntarily deferred. Additional portfolio managers may in the future manage other such accounts or funds and may be entitled to receive incentive fees. As a fiduciary, BlackRock owes a duty of loyalty to its clients and must treat each client fairly. When BlackRock purchases or sells securities for more than one account, the trades must be allocated in a manner consistent with its fiduciary duties. BlackRock attempts to allocate investments in a fair and equitable manner among client accounts, with no account receiving preferential treatment. To this end, BlackRock has adopted a policy that is intended to ensure that investment opportunities are allocated fairly and equitably among client accounts over time. This policy also seeks to achieve reasonable efficiency in client transactions and provide BlackRock with sufficient flexibility to allocate investments in a manner that is consistent with the particular investment discipline and client base. (a)(3) As of May 31, 2007: Portfolio Manager Compensation Portfolio Manager Compensation BlackRock's financial arrangements with its portfolio managers, its competitive compensation and its career path emphasis at all levels reflect the value senior management places on key resources. Compensation may include a variety of components and may vary from year to year based on a number of factors. The principal components of compensation include a base salary, a discretionary bonus, participation in various benefits programs and one or more of the incentive compensation programs established by BlackRock such as its Long-Term Retention and Incentive Plan and Restricted Stock Program. Base compensation Generally, portfolio managers receive base compensation based on their seniority and/or their position with the firm. Discretionary compensation In addition to base compensation, portfolio managers may receive discretionary compensation, which can be a substantial portion of total compensation. Discretionary compensation can include a discretionary cash bonus as well as one or more of the following: Long-Term Retention and Incentive Plan (LTIP) The LTIP is a long-term incentive plan that seeks to reward certain key employees. The plan provides for the grant of awards that are expressed as an amount of cash that, if properly vested and subject to the attainment of certain performance goals, will be settled in cash and/or in BlackRock, Inc. common stock. Deferred Compensation Program A portion of the compensation paid to each portfolio manager may be voluntarily deferred by the portfolio manager into an account that tracks the performance of certain of the firm's investment products. Each portfolio manager is permitted to allocate his deferred amounts among various options, including to certain of the firm's hedge funds and other unregistered products. In addition, prior to 2005, a portion of the annual compensation of certain senior managers was mandatorily deferred in a similar manner for a number of years. Beginning in 2005, a portion of the annual compensation of certain senior managers was paid in the form of BlackRock, Inc. restricted stock units which vest ratably over a number of years. Options and Restricted Stock Awards While incentive stock options are not currently being awarded to BlackRock employees, BlackRock, Inc. previously granted stock options to key employees, including certain portfolio managers who may still hold unexercised or unvested options. BlackRock, Inc. also has a restricted stock award program designed to reward certain key employees as an incentive to contribute to the long-term success of BlackRock. These awards vest over a period of years. Incentive Savings Plans BlackRock, Inc. has created a variety of incentive savings plans in which BlackRock employees are eligible to participate, including an Employee Stock Purchase Plan (ESPP) and a 401(k) plan. The 401(k) plan may involve a company match of the 50% employee's pre-tax contribution of up to 6% of the employee's salary, limited to $4,000 per year. BlackRock also offers a Company Retirement Contribution equal to 3% to 5% of eligible compensation, depending on BlackRock, Inc.'s overall net operating income. The company match is made in cash. The firm's 401(k) plan offers a range of investment options, including registered investment companies managed by the firm. Each portfolio manager is eligible to participate in these plans. Annual incentive compensation for each portfolio manager is a function of several components: the performance of BlackRock, Inc., the performance of the portfolio manager's group within BlackRock, the investment performance, including risk-adjusted returns and income generation, of the firm's assets under management or supervision by that portfolio manager relative to predetermined benchmarks, and the individual's teamwork and contribution to the overall performance of these portfolios and BlackRock. Unlike many other firms, portfolio managers at BlackRock compete against benchmarks rather than each other. In most cases, including for the portfolio managers of the Registrant, these benchmarks are the same as the benchmark or benchmarks against which the investment performance, including risk-adjusted returns and income generation, of the Registrant or other accounts are measured. These benchmarks include customized benchmarks, Lipper peer groups and a subset of other closed-end taxable debt funds. A group of BlackRock, Inc.'s officers determines which benchmarks against which to compare the performance of funds and other accounts managed by each portfolio manager. With respect to the Registrant, such benchmarks include the CSFB High Yield Index. The group of BlackRock, Inc.'s officers then makes a subjective determination with respect to the portfolio manager's compensation based on the performance of the funds and other accounts managed by each portfolio manager relative to the various benchmarks. This determination may take into consideration the fact that a benchmark may not perfectly correlate to the way the Registrant or other accounts are managed, even if it is the benchmark that is most appropriate for the Registrant or other account. For example, a benchmark's return may be based on the total return of the securities comprising the benchmark, but the Registrant or other account may be managed to maximize income and not total return. Senior portfolio managers who perform additional management functions within BlackRock may receive additional compensation for serving in these other capacities.
