The Benefits and Risks of Leveraging

BlackRock Diversified Income Strategies Fund, Inc. utilizes leveraging through
borrowings or issuance of short-term debt securities or shares of Preferred
Stock. The concept of leveraging is based on the premise that the cost of assets
to be obtained from leverage will be based on short-term interest rates, which
normally will be lower than the income earned by the Fund on its longer-term
portfolio investments. To the extent that the total assets of the Fund
(including the assets obtained from leverage) are invested in higher-yielding
portfolio investments, the Fund's Common Stock shareholders will be 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.

Announcement of Annual Stockholders Meeting

The Fund has determined that its annual stockholders meeting originally
scheduled to be held in April 2007 will be postponed and will be held in
September 2007. Proposals of stockholders intended to be presented at the
meeting must be received by the Fund by May 15, 2007 for inclusion in the Fund's
proxy statement and form of proxy for that meeting. The persons named as proxies
in the proxy materials for the Fund's 2007 annual meeting of stockholders may
exercise discretionary authority with respect to any stockholder proposal
presented at such meeting if written notice of such proposal has not been
received by the Fund by July 1, 2007. Written proposals and notices should be
sent to the Secretary of the Fund, 800 Scudders Mill Road, Plainsboro, New
Jersey 08536.

A Letter to Shareholders

Dear Shareholder

The new year began on a positive note for most financial markets, continuing the
momentum from the fourth quarter of 2006. At the end of February, however,
global equity markets registered their first significant decline since last
summer. The market jitters were triggered by a significant setback in the
Chinese market and were exacerbated by several concerns, notably a weakening
economy, some disappointing corporate earnings announcements, geopolitical
concerns related to Iran's nuclear program and increasing delinquencies in the
subprime mortgage market. Despite the recent spate of volatility, underlying
stock market fundamentals appear quite sound, supported by a generally good
global economic backdrop, tame inflation, relatively low interest rates and
attractive valuations.

Not unlike the equity market, the bond market also has seen volatility recently
as observers have attempted to interpret mixed economic signals. A bond market
rally late last year reversed early in 2007 as the economic data strengthened.
Prices improved (and yields fell) again in February as equities struggled.
Notably, the Treasury curve remained inverted for much of 2006 and into 2007.
The 30-year Treasury yield stood at 4.68% on February 28, 2007, while the
one-month Treasury offered the highest yield on the curve at 5.24%.

For its part, the Federal Reserve Board (the Fed) has left the target short-term
interest rate on hold at 5.25% since first pausing on August 8, 2006. Although
the central bankers continue to express concern about potential inflationary
pressures, they also have made reference to signs of economic weakness in their
public statements. Most observers expect the Fed to keep interest rates on hold
for now, but acknowledge that the combination of a mild economic slowdown and
moderating inflation could prompt an interest rate cut later in 2007.

Notwithstanding the volatility along the way, most major market indexes managed
to post positive returns for the annual and semi-annual reporting periods ended
February 28, 2007:

If the recent market movements are any guide, 2007 could be a year of enhanced
market volatility. As you navigate the uncertainties of the financial markets,
we encourage you to review your investment goals with your financial

BlackRock with your investment assets, and we look forward to continuing to
serve you in the months and years ahead.

                                                     Sincerely,

BLACKROCK DIVERSIFIED INCOME STRATEGIES FUND, INC.      FEBRUARY 28, 2007     3


A Discussion With Your Fund's Portfolio Managers

      The Fund outpaced its benchmark return for the period and provided an
attractive yield as we continued our efforts to enhance the level of income
provided to shareholders.

How did the Fund perform during the period in light of the existing market
conditions?

For the six-month period ended February 28, 2007, the Common Stock of BlackRock
Diversified Income Strategies Fund, Inc. had net annualized yields of 9.45% and
9.17%, based on a period-end per share net asset value of $19.21 and a per share
market price of $19.80, respectively, and $.900 per share income dividends. Over
the same period, the total investment return on the Fund's Common Stock was
+7.73%, based on a change in net asset value from $18.70 to $19.21, and assuming
reinvestment of all distributions. By comparison, the Fund's benchmark, which is
comprised 20% of the Credit Suisse High Yield Index and 80% of the Credit Suisse
Leveraged Loan Index, posted a total return of +5.06% for the six-month period.

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 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 leveraged loan market, as measured by the Credit Suisse Leveraged Loan
Index, returned +4.19% for the semi-annual period, while the high yield bond
market, as measured by the Credit Suisse High Yield Index, returned +8.62%.
Despite some volatility late in the reporting period, the non-investment grade
markets continued to post strong results. The leveraged loan and the high yield
markets both posted positive returns in each of the past six months. The markets
have been aided by the continuation of historically low default rates and strong
inflows into the asset classes, both of which have helped to support the prices
of the underlying issues.

Support for the leveraged loan market also came from soaring investor demand,
which pushed spreads to new lows. The primary driver of this demand is
collateralized loan obligations (CLOs), which now account for approximately
two-thirds of the leveraged loan market. The cost of funding for these CLOs has
dropped dramatically over the past few years, enabling the structured finance
vehicles to absorb bank loans at increasingly tighter spreads and still achieve
their targeted equity returns. The fact that default rates are at historic lows
also has assisted this trend. To supply the CLO juggernaut, the demand for bank
loans has been so voracious that we have actually seen bond deals migrate to the
loan market, a reversal of historic flows that typically saw deals move from
loans into bonds. This trend has marginally curtailed the supply of high yield
bonds, keeping spreads there tighter than they otherwise would be.

What factors most influenced Fund performance?

Given the inverted shape of the yield curve, the Fund benefited from its
overweight exposure to floating rate high yield bonds and bank loans, as opposed
to fixed rate high yield issues. The Fund's performance also was aided by its
overweight exposure to lower-tier credits, particularly B-rated and CCC-rated
issues, as these segments of the non-investment grade market generated the
strongest returns. Given the relative strength of the market, we continued to
make extensive use of the Fund's leverage line, with an average level of about
30% of total assets. This, too, proved beneficial to performance. (For a
complete explanation of the benefits and risks of leveraging, refer to page 2 of
this report to shareholders.)

What changes were made to the Fund during the period?

During the period, BlackRock, Inc. and Merrill Lynch & Co., Inc. ("Merrill
Lynch") combined Merrill Lynch's investment management business, Merrill Lynch
Investment Managers, L.P. and its affiliates, including Fund Asset Management,
L.P., with BlackRock, Inc. to form a new independent company. While this
resulted in some additions to the portfolio management team, there was no change
in the overall investment philosophy or focus of the Fund. The most notable
shift in sector exposures occurred in the automotive sector, where we reduced
our underweight position during the period.


4     BLACKROCK DIVERSIFIED INCOME STRATEGIES FUND, INC.      FEBRUARY 28, 2007


How would you characterize the Fund's position at the close of the period?

While volatility picked up at the end of the period, resulting in an investor
flight to quality, fundamental and technical valuations remained favorable for
the leveraged loan and high yield markets. Even with the noise at the end of the
reporting period, the leveraged loan market posted a return of +.74% in
February, while the high yield market posted a return of better than +1%. This
marked the seventh month out of eight in which the Credit Suisse High Yield
Index posted monthly returns in excess of 1% and the eighth consecutive month
that the Credit Suisse Leveraged Loan Index posted returns of at least +.50%.

Market fundamentals remain very strong, with default rates near historic lows
and a new-issue calendar that is just beginning to satisfy the non-investment
grade investor. As a result, we remain positioned with an overweight to
lower-tier credits (B and CCC), as we expect these segments of the market to
post the strongest returns.

16     BLACKROCK DIVERSIFIED INCOME STRATEGIES FUND, INC.      FEBRUARY 28, 2007


Notes to Financial Statements (Unaudited)

1. Significant Accounting Policies:

BlackRock Diversified Income Strategies Fund, Inc. (the "Fund") is registered
under the Investment Company Act of 1940, as amended, as a diversified,
closed-end management investment company. The Fund's financial statements are
prepared in conformity with U.S. generally accepted accounting principles, which
may require the use of management accruals and estimates. Actual results may
differ from these estimates. These unaudited financial statements reflect all
adjustments, which are, in the opinion of management, necessary to present a
fair statement of the results for the interim period. All such adjustments are
of a normal, recurring nature. The Fund determines and makes available for
publication the net asset value of its Common Stock on a daily basis. The Fund's
Common Stock shares are listed on the New York Stock Exchange ("NYSE") under the
symbol DVF.

(a) Corporate debt obligations -- The Fund invests principally in debt
obligations of companies, including loan interests made by banks and other
financial institutions and both privately and publicly offered corporate bonds
and notes. Because agents and intermediaries are primarily commercial banks or
other financial institutions, the Fund's investment in loan interests could be
considered concentrated in financial institutions.

(b) Valuation of investments -- Loan interests are valued in accordance with
guidelines established by the Board of Directors. As of October 2, 2006,
floating rate loan interests will be valued at the mean between the last
available bid prices from one or more brokers or dealers as obtained from the
Loan Pricing Corporation. Previously, floating rate loan interests were valued
at the mean between the last available bid and asked prices as obtained from the
same pricing source. This change had no significant effect on the valuation of
these loans. For the limited number of loan interests for which no reliable
price quotes are available, such loan interests may be valued by Loan Pricing
Corporation through the use of pricing matrixes to determine valuations. If the
pricing service does not provide a value for loan interests, BlackRock Advisors,
LLC (the "Manager"), a wholly owned subsidiary of BlackRock, Inc., will value
the loan interests at fair value, which is intended to approximate market value.

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. Pricing services use valuation matrixes
that incorporate both dealer-supplied valuations and valuation models. The
procedures of the pricing service and its valuations are reviewed by the
officers of the Fund under the general direction of the Board of Directors. Such
valuations and procedures will be reviewed periodically by the Board of
Directors of the Fund.

Securities held by the Fund that are traded on stock exchanges or the NASDAQ
Global Market are valued at the last sale price or official close price on the
exchange on which such securities are traded, as of the close of business on the
day the securities are being valued or, lacking any sales, at the last available
bid price for long positions, and at the last available asked price for short
positions. In cases where securities are traded on more than one exchange, the
securities are valued on the exchange designated as the primary market by or
under the authority of the Board of Directors of the Fund. Long positions in
securities traded in the OTC market, NASDAQ Capital Market or Bulletin Board are
valued at the last available bid price or yield equivalent obtained from one or
more dealers or pricing services approved by the Board of Directors of the Fund.
Short positions in securities traded in the OTC market are valued at the last
available asked price. Portfolio securities that are traded both in the OTC
market and on a stock exchange are valued according to the broadest and most
representative market. When the Fund writes an option, the amount of the premium
received is recorded on the books of the Fund as an asset and an equivalent
liability. The amount of the liability is subsequently valued to reflect the
current market value of the option written, based on the last sale price in the
case of exchange-traded options or, in the case of options traded in the OTC
market, the last asked price. Options purchased by the Fund are valued at their
last sale price in the case of exchange-traded options or, in the case of
options traded in the OTC market, the last bid price. Swap agreements are valued
based upon quoted fair valuations received daily by the Fund from a pricing
service or counterparty. Other investments, including futures contracts and
related options, are stated at market value. Obligations with remaining
maturities of 60 days or less are valued at amortized cost unless the Manager
believes that this method no longer produces fair valuations. Valuation of other
short-term investment vehicles is generally based on the net asset value of the
underlying investment vehicle or amortized cost. Repurchase agreements will be
valued at cost plus accrued interest.

Generally, trading in foreign securities, as well as U.S. government securities,
money market instruments and certain fixed income securities, is substantially
completed each day at various times prior to the close of business on the NYSE.
The values of such securities used in computing the net asset


BLACKROCK DIVERSIFIED INCOME STRATEGIES FUND, INC.      FEBRUARY 28, 2007     17


Notes to Financial Statements (continued)

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 the Manager using a pricing service and/or procedures
approved by the Fund's Board of Directors.

(c) Derivative financial instruments -- The Fund may engage in various portfolio
investment strategies both to increase the return of the Fund and to hedge, or
protect, its exposure to interest rate movements and movements in the securities
markets. Losses may arise due to changes in the value of the contract due to an
unfavorable change in the price of the underlying security or index or if the
counterparty does not perform under the contract.

o     Financial futures contracts -- The Fund may purchase or sell financial
      futures contracts and options on such financial futures contracts.
      Financial futures contracts are contracts for delayed delivery of
      securities at a specific future date and at a specific price or yield.
      Upon entering into a contract, the Fund deposits and maintains as
      collateral such initial margin as required by the exchange on which the
      transaction is effected. Pursuant to the contract, the Fund agrees to
      receive from or pay to the broker an amount of cash equal to the daily
      fluctuation in value of the contract. Such receipts or payments are known
      as variation margin and are recorded by the Fund as unrealized gains or
      losses. When the contract is closed, the Fund records a realized gain or
      loss equal to the difference between the value of the contract at the time
      it was opened and the value at the time it was closed.

o     Options -- The Fund may write and purchase call and put options. When the
      Fund writes an option, an amount equal to the premium received by the Fund
      is reflected as an asset and an equivalent liability. The amount of the
      liability is subsequently marked-to-market to reflect the current market
      value of the option written. When a security is purchased or sold through
      an exercise of an option, the related premium paid (or received) is added
      to (or deducted from) the basis of the security acquired or deducted from
      (or added to) the proceeds of the security sold. When an option expires
      (or the Fund enters into a closing transaction), the Fund realizes a gain
      or loss on the option to the extent of the premiums received or paid (or
      gain or loss to the extent the cost of the closing transaction is less
      than or exceeds the premiums paid or received).

      Written and purchased options are non-income producing investments.

o     Swaps -- The Fund may enter into swap agreements, which are OTC contracts
      in which the Fund and a counterparty agree to make periodic net payments
      on a specified notional amount. The net payments can be made for a set
      period of time or may be triggered by a predetermined credit event. The
      net periodic payments may be based on a fixed or variable interest rate;
      the change in market value of a specified security, basket of securities,
      or index; or the return generated by a security. These periodic payments
      received or made by the Fund are recorded in the accompanying Statement of
      Operations as realized gains or losses, respectively. Gains or losses are
      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 swap
      agreements.

(d) Foreign currency transactions -- Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of
settling (realized) or valuing (unrealized) assets or liabilities expressed in
foreign currencies into U.S. dollars. Realized and unrealized gains or losses
from investments include the effects of foreign exchange rates on investments.
The Fund invests in foreign securities, which may involve a number of risk
factors and special considerations not present with investments in securities of
U.S. corporations.

(e) Income taxes -- It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no federal income tax provision is required.


18     BLACKROCK DIVERSIFIED INCOME STRATEGIES FUND, INC.      FEBRUARY 28, 2007


Notes to Financial Statements (continued)

(f) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Interest income is recognized on the accrual basis. The
Fund amortizes all premiums and discounts on debt securities.

(g) Offering costs -- Direct expenses relating to the public offering of the
Fund's Common Stock were charged to capital.

(h) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates. The Fund may at times pay out less than the entire amount of
net investment income earned in any particular period and may at times pay out
such accumulated undistributed income in other periods to permit the Fund to
maintain a more stable level of dividends.

(i) Securities lending -- The Fund may lend securities to financial institutions
that provide cash or securities issued or guaranteed by the U.S. government as
collateral, which will be maintained at all times in an amount equal to at least
100% of the current market value of the loaned securities. The market value of
the loaned securities is determined at the close of business of the Fund and any
additional required collateral is delivered to the Fund on the next business
day. Where the Fund receives securities as collateral for the loaned securities,
it collects a fee from the borrower. The Fund typically receives the income on
the loaned securities but does not receive the income on the collateral. Where
the Fund receives cash collateral, it may invest such collateral and retain the
amount earned on such investment, net of any amount rebated to the borrower.
Loans of securities are terminable at any time and the borrower, after notice,
is required to return borrowed securities within five business days. The Fund
may pay reasonable finder's, lending agent, administrative and custodial fees in
connection with its loans. In the event that the borrower defaults on its
obligation to return borrowed securities because of insolvency or for any other
reason, the Fund could experience delays and costs in gaining access to the
collateral. The Fund also could suffer a loss where the value of the collateral
falls below the market value of the borrowed securities, in the event of
borrower default or in the event of losses on investments made with cash
collateral.

(j) Bank overdraft -- The Fund recorded a bank overdraft, which resulted from
management estimates of available cash.

(k) Recent accounting pronouncements -- In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting
for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109."
FIN 48 prescribes the minimum recognition threshold a tax position must meet in
connection with accounting for uncertainties in income tax positions taken or
expected to be taken by an entity including mutual funds before being measured
and recognized in the financial statements. 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.

2. Investment Advisory Agreement and Transactions with Affiliates:

On September 29, 2006, BlackRock, Inc. and 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. ("), with BlackRock, Inc. to create a new independent company.
Merrill Lynch has a 49.8%


BLACKROCK DIVERSIFIED INCOME STRATEGIES FUND, INC.      FEBRUARY 28, 2007     19


Notes to Financial Statements (continued)

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.

The Investment Advisory Agreement between the Fund and the Manager became
effective on September 29, 2006. Prior to September 29, 2006, FAM was the Fund's
Manager. The general partner of FAM is Princeton Services, Inc. ("PSI"), 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 .75% of the Fund's average daily net
assets plus the proceeds of any outstanding borrowings used for leverage. In
addition, the Manager has entered into a Sub-Advisory Agreement with BlackRock
Financial Management, Inc., an affiliate of the Manager, under which the Manager
pays the Sub-Adviser for services it provides a monthly fee that is a percentage
of the management fee paid by the Fund to the Manager.

The Fund has received an exemptive order from the Securities and Exchange
Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S"), an affiliate of the Manager, 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 MLIM, 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.

For the six months ended February 28, 2007, the Fund reimbursed FAM and the
Manager $335 and $1,675, 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, PSI, MLIM, Merrill Lynch, and/or MLIM, LLC.

                is responsible for the day-to-day management of the Fund's

                founding member of the bank's Leveraged Finance Group. In that
                capacity he was responsible for structuring proprietary middle
                market leveraged deals and sourcing and evaluating broadly
                syndicated leveraged loans in the primary and secondary markets
                for PNC Bank's investment portfolio. From 1984 until 1990, Mr.

                                                                                           (iii) Number of Other Accounts and

         (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 February 28, 2007:

                  Compensation Program

                  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 a 401(k) plan, the BlackRock Retirement Savings Plan (RSP)
         and the BlackRock Employee Stock Purchase Plan (ESPP). The employer
         contribution components of the RSP include a company match equal to 50%
         of the first 6% of eligible pay contributed to the plan capped at
         $4,000 per year, and a company retirement contribution equal to 3% of
         eligible compensation, plus an additional contribution of 2% for any
         year in which BlackRock has positive net operating income. The RSP
         offers a range of investment options, including registered investment
         companies managed by the firm. Company contributions follow the
         investment direction set by participants for their own contributions or
         absent, employee investment direction, are invested into a stable value
         fund. The ESPP allows for investment in BlackRock common stock at a 5%
         discount on the fair market value of the stock on the purchase date.
         Annual participation in the ESPP is limited to the purchase of 1,000
         shares or a dollar value of $25,000. 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. 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.

                  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 February 28, 2007, Mr.
                Booth beneficially owns stock issued by the Fund in the range of
                $100,001-$500,000. As of February 28, 2007, Mr. Williams does

Item 11 - Controls and Procedures

11(a) - The registrant's certifying officers have reasonably designed such
        disclosure controls and procedures to ensure material information
        relating to the registrant is made known to us by others particularly
        during the period in which this report is being prepared. The
        registrant's certifying officers have determined that the registrant's
        disclosure controls and procedures are effective based on our evaluation
        of these controls and procedures as of a date within 90 days prior to
        the filing date of this report.

11(b) - As of September 29, 2006, with the conclusion of the combination of
        Merrill Lynch's asset management business with BlackRock, the registrant
        was migrated to BlackRock's trading and compliance monitoring systems,
        and various personnel changes occurred. In conjunction with these
        business improvements, there were no changes in the registrants internal
        control over financial reporting (as defined in Rule 30a-3(d) under Act
        (17 CFR 270.30a-3(d)) that occurred during the last fiscal half-year of
        the period covered by this report that has materially affected, or is
        reasonably likely to affect, the registrant's internal control over
        financial reporting.
