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.

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:

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.

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.

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.

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.

Contact Information -- All correspondence concerning the Plan, including any
questions about the Plan, should be directed to the Plan Agent at Computershare
Trust Company, N.A., P.O. Box 43010, Providence, RI 02940-3010, Telephone:

          (e)(1) The registrant's audit committee (the "Committee") has adopted
          policies and procedures with regard to the pre-approval of services.
          Audit, audit-related and tax compliance services provided to the
          registrant on an annual basis require specific pre-approval by the
          Committee. The Committee also must approve other non-audit services
          provided to the registrant and those non-audit services provided to
          the registrant's affiliated service providers that relate directly to
          the operations and the financial reporting of the registrant. Certain
          of these non-audit services that the Committee believes are a)
          consistent with the SEC's auditor independence rules and b) routine
          and recurring services that will not impair the independence of the
          independent accountants may be approved by the Committee without
          consideration on a specific case-by-case basis ("general
          pre-approval"). However, such services will only be deemed
          pre-approved provided that any individual project does not exceed
          $5,000 attributable to the registrant or $50,000 for all of the
          registrants the Committee oversees. Any proposed services exceeding
          the pre-approved cost levels will require specific pre-approval by the
          Committee, as will any other services not subject to general
          pre-approval (e.g., unanticipated but permissible services). The
          Committee is informed of each service approved subject to general
          pre-approval at the next regularly scheduled in-person board meeting.

          ongoing services to the registrant that were not pre-approved pursuant
          to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible

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.

          (iv) Potential Material Conflicts of Interest

          BlackRock has built a professional working environment, firm-wide
          compliance culture and compliance procedures and systems designed to
          protect against potential incentives that may favor one account over
          another. 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.

          (a)(4) Beneficial Ownership of Securities. As of May 31, 2007, none of
          Messrs. Amero, Gary, Baumgarten and Keenan beneficially owned any
          stock issued by the Fund.

Item 9 -  Purchases of Equity Securities by Closed-End Management Investment
          Company and Affiliated Purchasers - Not Applicable

Item 10 - Submission of Matters to a Vote of Security Holders - The registrant's
          Nominating Committee will consider nominees to the Board recommended
          by shareholders when a vacancy becomes available. Shareholders who
          wish to recommend a nominee should send nominations which include
          biographical information and set forth the qualifications of the
          proposed nominee to the registrant's Secretary. There have been no
          material changes to these procedures.

Item 11 - Controls and Procedures

11(a) -   The registrant's principal executive and principal financial officers
          or persons performing similar functions have concluded that the
          registrant's disclosure controls and procedures (as defined in Rule
          30a-3(c) under the Investment Company Act of 1940, as amended (the
          "1940 Act")) are effective as of a date within 90 days of the filing

          13a-15(b) under the Securities and Exchange Act of 1934, as amended.



11(b) -   There were no changes in the registrant's internal control over
          financial reporting (as defined in Rule 30a-3(d) under the 1940 Act
          (17 CFR 270.30a-3(d)) that occurred during the second fiscal quarter
          of the period covered by this report that have materially affected, or
          are reasonably likely to materially affect, the registrant's internal
          control over financial reporting.
