A Letter to Shareholders

Dear Shareholder

The present times may well be remembered as one of the most tumultuous periods in financial market history. Over the past year, the bursting of the housing bubble and the resultant credit crisis mushroomed into an all-out global financial market meltdown, featuring the collapse of storied financial firms, volatile swings in the world’s financial markets and monumental government responses designed to rescue the beleaguered financial system.

The U.S. economy appeared relatively resilient through the first half of 2008, when rising food and energy prices stoked fears of inflation. The tenor changed dramatically in the second half, as inflation pressures subsided amid plummeting oil prices, but a uniform and rapid deterioration in key economic indicators darkened growth prospects. Just after the close of the reporting period, the National Bureau of Economic Research officially declared that the U.S. was in a recession, and that it had begun in December 2007. The Federal Reserve Board (the “Fed”), after slashing interest rates aggressively in the early months of the year, resumed that rate-cutting campaign in the fall, bringing the target federal funds rate to a record low range of between zero to 0.25% on December 16. More significant was the central bank’s pledge that future policy moves to revive the global economy and financial markets would comprise primarily nontraditional and quantitative easing measures, such as capital injections, lending programs and government guarantees.

Against this backdrop, U.S. equity markets experienced intense volatility, with periods of downward pressure punctuated by sharp rebounds. Losses were significant and broad-based, though non-U.S. markets decelerated at a considerably faster pace than domestic equities — a stark reversal of prior years’ trends, when international stocks generally outpaced U.S. stocks.

Treasury issues also traded in a volatile fashion, but rallied overall (yields fell and prices correspondingly rose) and outperformed other fixed income assets as investors retreated to the safest and most liquid investments. Amid spillover from historic events in the financial sector, municipals contended with fewer market participants, lack of liquidity, a challenging funding environment and a backlog of new-issue supply, all of which contributed to the sector’s underperformance relative to its taxable counterparts. Similarly, economic turmoil and badly broken credit markets plagued the high yield sector, with the third quarter of 2008 marking one of the worst periods in history for the asset class.

In all, an investor flight to safety prevailed, as evidenced in the six- and 12-month returns of the major benchmark indexes:

Fund Summary as of November 30, 2008	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”)) or are unrated securities of comparable quality.

Performance

For the six months ended November 30, 2008, the Fund returned (47.14)% based on market price and (40.70)% 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 (42.62)% on a NAV basis. All returns reflect reinvestment of dividends. The Fund’s discount to NAV widened from 6% to 16% during the period, which hurt price performance relative to NAV performance. Overall, an underweight in BB-rated issues and overweight in CCC-rated securities hurt relative performance for the period, while defensive sector positioning and credit selection helped. The Fund maintained less leverage than many of its Lipper peers and had an allocation to bank loans, both of which proved advantageous.

The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

SEMI-ANNUAL REPORT NOVEMBER 30, 2008 5

The Benefits and Risks of Leveraging

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

The Funds may utilize leverage through borrowings and the issuance of short-term securities and Preferred Shares. 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 Common Shareholders will benefit from the incremental yield.

The interest earned on securities purchased with the proceeds from leverage is paid to Common Shareholders in the form of dividends, and the value of these portfolio holdings is reflected in the per share NAV of each Fund’s Common Shares. However, in order to benefit Common 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, returns to Common Shareholders will be lower than if the Funds had not used leverage.

To illustrate these concepts, assume a Fund’s Common Shares 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 Fund’s total portfolio of $130 million earns 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 Common Shareholders are the beneficiaries of the incremental yield.

Conversely, 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. If short-term interest rates rise, narrowing the differential between short-term and long-term interest rates, the incremental yield pickup on the Common Shares will be reduced or eliminated completely.

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 returns to the Funds and Common 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 or below fair market 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, such as in the case of certain restrictions imposed by ratings agencies that rate preferred shares issued by a Fund. A Fund will incur expenses in connection with the use of leverage, all of which are borne by the holders of the Common Shares and may reduce returns on the Common Shares.

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 total managed assets. As of November 30, 2008, the Funds had outstanding leverage from credit facility borrowings as a percentage of total managed assets as follows:

	Percent of Leverage
BlackRock Corporate High Yield Fund, Inc.	31	%
BlackRock Corporate High Yield Fund III, Inc.	31	%

Derivative Instruments

The Funds may invest in various derivative instruments, including swap agreements, futures and forward currency contracts, and other instruments specified in the Notes to Financial Statements, which constitute additional 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 other party 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 prices other than current market 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.

•	Effective June 1, 2008, the Fund adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“FAS 157”). FAS 157 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 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 circumstance, to the extent observable inputs are not available (including the Fund’s own assumption 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 November 30, 2008 in determining the fair valuation of the Fund’s investments:

Valuation Inputs	Investments in Securities		Other Financial Instruments*
Level 1	$	1,694,641		—
Level 2		192,117,048	$	(2,882,501	)
Level 3		14,662,878		—
Total	$	208,474,567	$	(2,882,501	)

*	Other financial instruments are foreign currency exchange contracts, options and swaps.
The following is a reconciliation of investments for unobservable inputs (Level 3) used in determining fair value:

	Investments in Securities
Balance, as of June 1, 2008	$	3,582
Accrued discounts/premiums		17,368
Realized gain		636
Change in unrealized depreciation		(8,074,606	)

•	Effective June 1, 2008, the Fund adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“FAS 157”). FAS 157 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 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 circumstance, to the extent observable inputs are not available (including the Fund’s own assumption 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 November 30, 2008 in determining the fair valuation of the Fund’s investments:

Valuation Inputs	Investments in Securities		Other Financial Instruments*
Level 1	$	1,912,129		—
Level 2		201,649,511	$	(3,220,616	)
Level 3		15,889,647		—
Total	$	219,451,287	$	(3,220,616	)

*	Other financial instruments are swaps, foreign currency exchange contracts and options.
The following is a reconciliation of investments for unobservable inputs (Level 3) used in determining fair value:

	Investments in Securities
Balance, as of June 1, 2008	$	3,837
Accrued discounts/premiums		4,250
Realized gain		529

Notes to Financial Statements (Unaudited)

1. Organization and Significant Accounting Policies:

BlackRock Corporate High Yield Fund, Inc. and BlackRock Corporate High Yield Fund III, Inc. (the “Funds” or individually the “Fund”) are registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as diversified, closed-end management investment companies. The Funds are organized as Maryland corporations. 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 price 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. Short-term securities are valued at amortized cost. Investments in open-end investment companies are valued at net asset value each business day. The Funds value their investment in the BlackRock Liquidity Series, LLC Cash Sweep Series 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 (long positions) or ask (short positions) price. If no bid or ask price is available, the prior day’s price will be used unless it is determined that the 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 date factors.

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, 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 each 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.

Derivative Financial Instruments: The Funds may engage in various portfolio investment strategies both to increase the return of the Funds and to hedge, or protect, their exposure to interest rate movements and movements in the securities markets. Losses may arise if the value of the contract decreases due to an unfavorable change in the price of the underlying security, or if the counterparty does not perform under the contract.

• Forward currency contracts — A forward currency contract is an agreement between two parties to buy and sell a currency at a set exchange rate on a future date. The Funds may enter into foreign currency contracts as a hedge against either specific transactions or portfolio positions. Foreign currency contracts, when used by the Funds, help to manage the overall exposure to the foreign currency backing some of the investments held by the Funds. The contract is marked-to-market daily and the change in market value is recorded by the Funds as an unrealized gain or loss. When the contract is closed, the Funds record 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 forward foreign currency contracts involves the risk that counterparties

SEMI-ANNUAL REPORT NOVEMBER 30, 2008 27

Notes to Financial Statements (continued)

	may not meet the terms of the agreement and market risk of unanticipated movements in the value of a foreign currency relative to the U.S. dollar.
•	Options — The Funds may purchase and write call and put options. 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 position 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 position 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) by the Fund is reflected as an asset and an equivalent liability. The amount of the asset (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 received or paid). When a Fund writes a call option, such option is “covered,” meaning that the Fund holds the underlying security 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. Certain call options are written as part of an arrangement where the counterparty to the transaction borrows the underlying security from the Fund in a securities lending transaction.
	In purchasing and writing options, the Funds bear the market risk of an unfavorable change in the price of the underlying security. 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 OTC options. Transactions in certain OTC options may expose the Funds to the risk of default by the counterparty to the transactions.
•	Credit default swaps — The Funds may enter into credit default swaps for investment purposes or to manage their credit risk. The Funds may enter into swap agreements, in which the Funds and the counterparty agree to make periodic net payments on a specified notional amount. Credit default swaps are agreements in which one party pays fixed periodic payments to a counterparty in consideration for a guarantee from the counterparty to make a specific payment should a negative credit event take place (e.g., default, bankruptcy or debt restructuring). The Funds may either buy or sell (write) credit default swaps. As a buyer, the Funds 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), the Funds 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. In the event of default by the counterparty, the Funds may recover amounts paid under the agreement either partially or in total by offsetting any payables and/or receivables with collateral held or pledged. These periodic payments received or made by the Funds are recorded in the accompanying 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 Funds will record a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Funds’ basis in the contract, if any. Swap transactions involve, to varying degrees, elements of credit and market risk in excess of the amounts recognized on the Statements of Assets and Liabilities. Such risk involves 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 there may be unfavorable changes in interest rates and/or market values associated with these transactions.

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.

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

28 SEMI-ANNUAL REPORT NOVEMBER 30, 2008

Notes to Financial Statements (continued)

LIBOR (London InterBank Offered Rate), (ii) the prime rate offered by one or more U.S. 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 recorded 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. Each Fund will have the right to receive payments of principal, interest and any fees to which it is 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 creditors of the lender and may not benefit from any offset between the lender and the borrower.

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.

Each Fund reports 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.

Preferred Stock: The 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.

Segregation and Collateralization: In cases in which the 1940 Act and the interpretive positions of the Securities and Exchange Commission (“SEC”) require that the Funds segregate assets in connection with certain investments (e.g., forward foreign currency contracts and swaps) and certain borrowings, each Fund will, consistent with certain interpretive letters issued by the SEC, 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 Fund may also be required to deliver or deposit securities as collateral for certain investments (e.g., swaps).

Investment Transactions and Investment Income: 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. The Funds amortize 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.

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.

SEMI-ANNUAL REPORT NOVEMBER 30, 2008 29

Notes to Financial Statements (continued)

The Funds file U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Funds’ tax returns remains open for the years ended May 31, 2005 through May 31, 2007. 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 March 2008, Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities — an amendment of FASB Statement No. 133” (“FAS 161”), was issued. FAS 161 is intended to improve financial reporting for derivative instruments by requiring enhanced disclosure that enables investors to understand how and why an entity uses derivatives, how derivatives are accounted for, and how derivative instruments affect an entity’s results of operations and financial position. FAS 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. The impact 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”) 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 the Funds. 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.

Bank Overdraft: BlackRock Corporate High Yield Fund III, Inc. recorded a bank overdraft, which resulted from estimates of available cash.

Other: Expenses directly related to each 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. Investment Advisory Agreement and Other Transactions with Affiliates:

Each Fund entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the “Advisor”), an indirect, wholly owned subsidiary of BlackRock, Inc., to provide investment advisory and administration services. Merrill Lynch & Co., Inc. (“Merrill Lynch”), a wholly owned subsidiary of Bank of America Corporation (“BAC”), and The PNC Financial Services Group, Inc. are the largest stockholders of BlackRock, Inc.

The Advisor 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, BlackRock Corporate High Yield, Inc. and BlackRock Corporate High Yield III, Inc. pay the Advisor a monthly fee at an annual rate of 0.50% and 0.60%, respectively, of the average daily value of each Fund’s net assets, plus the proceeds of any outstanding borrowings used for leverage.

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

For the six months ended November 30, 2008, the Funds reimbursed the Advisor for certain accounting services, which are included in accounting services in the Statements of Operations. The reimbursements were as follows:

	Reimbursement to Advisor
BlackRock Corporate High Yield Fund, Inc.	$	2,041
BlackRock Corporate High Yield Fund III, Inc.	$	2,295

Pursuant to the terms of the custody agreement, custodian fees may be reduced by amounts calculated on uninvested cash balances (“custody credits”), which are shown on the Statement of Operations as fees paid indirectly.

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

3. Investments:

Purchases and sales (including paydowns) of investments, excluding short-term securities, for the six months ended November 30, 2008 were as follows:

	BlackRock Corporate High Yield Fund, Inc.		BlackRock Corporate High Yield Fund III, Inc.
Total Purchases	$	71,500,242	$	73,359,259
Total Sales	$	80,223,624	$	82,707,298

Notes to Financial Statements (concluded)

4. Capital Share Transactions:

Each Fund is authorized to issue 200,000,000 shares, all of which were initially classified as Common Shares. The Board is authorized, however, to classify and reclassify any unissued shares without approval of the holders of Common Shares.

Shares issued and outstanding for the Funds during the six months ended November 30, 2008 and the year ended May 31, 2008 remained constant.

5. Commitments:

BlackRock Corporate High Yield Fund III, Inc. may invest in floating rate loans. In connection with these investments, the Fund may, with its Advisor, also enter into unfunded corporate loans (“commitments”). Commitments may obligate the Fund to furnish temporary financing to a borrower until permanent financing can be arranged. As of November 30, 2008, the Fund had the following unfunded loan commitment:

Borrower	Unfunded Commitment (000)		Value of Underlying Loan
Community Health Systems, Inc.		158	$	123,910

6. Short-Term Borrowings:

On May 16, 2008, the Funds renewed their revolving credit and security agreements 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 of $135,000,000 for BlackRock Corporate High Yield, Inc. and $143,000,000 for BlackRock Corporate High Yield III, Inc.

Under the Citicorp program, the conduits will fund advances to each Fund through the issuance of highly rated commercial paper. Each Fund has 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 is based on the interest rate carried by the commercial paper plus a program fee. In addition, each Fund pays a liquidity fee to the secondary backstop lenders and the agent. These amounts are shown on the Statements of Operations as borrowing costs.

Under the agreement, the Funds are subject to certain conditions and covenants, which include 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, which included a reduction of the maximum limits to $81,000,000 and $85,000,000 for BlackRock Corporate High Yield Inc. and BlackRock Corporate High Yield III, Inc., respectively, waivers of certain financial covenants by the Lenders, and an increase in program and liquidity fees under the facility.

For the six months ended November 30, 2008, the daily weighted average interest rates were as follows:

	Daily Weighted Average Interest Rate
BlackRock Corporate High Yield Fund, Inc.		3.70%
BlackRock Corporate High Yield Fund III, Inc.		3.70%

7. Capital Loss Carryforward:

As of May 31, 2008, the Funds had capital loss carryforwards available to offset future realized capital gains through the indicated year of expiration:

Expires May 31,	BlackRock Corporate High Yield Fund, Inc.		BlackRock Corporate High Yield Fund III, Inc.
2009	$	25,513,921	$	34,200,029

SEMI-ANNUAL REPORT NOVEMBER 30, 2008 33

Additional Information (concluded)

General Information

The Funds do not make available copies of their Statements of Additional Information because the Funds’ shares are not continuously offered, which means that the Statements of Additional Information of the Funds have not been updated after completion of the Funds’ offering and the information contained in the Funds’ Statements of Additional Information may have become outdated.

During the period, there were no material changes in the Funds’ investment objectives or policies or to the Funds’ charters or by-laws that were not approved by the shareholders or in the principal risk factors associated with investment in the Funds. There have been no changes in the persons who are primarily responsible for the day-to-day management of the Funds’ portfolios.

The Funds will mail only one copy of shareholder documents, including annual and semi-annual reports and proxy statements, to shareholders with multiple accounts at the same address. This practice is commonly called “householding” and it is intended to reduce expenses and eliminate duplicate mailings of shareholder documents. Mailings of your shareholder documents may be householded indefinitely unless you instruct us otherwise. If you do not want the mailing of these documents to be combined with those for other members of your household, please contact the Funds at (800) 441-7762.

Quarterly performance, semi-annual and annual reports and other information regarding the Funds may be found on BlackRock’s website, which can be accessed at http://www.blackrock.com. This reference to BlackRock’s website is intended to allow investors public access to information regarding the Funds and does not, and is not intended to, incorporate BlackRock’s website into this report.
