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
professional and to make portfolio changes, as needed. We thank you for
trusting BlackRock with your investment assets, and we look forward to
continuing to serve you in the months and years ahead.


Sincerely,

A Discussion With Your Fund's Portfolio Managers


The Fund outperformed its composite benchmark for the six-month period,
benefiting primarily from its use of leverage.


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 Floating Rate Income Strategies Fund, Inc. had net annualized yields
of 8.38% and 8.68%, based on a period-end per share net asset value of $19.56
and a per share market price of $18.88, respectively, and $.812 per share
income dividends. Over the same period, the total investment return on the
Fund's Common Stock was +5.86%, based on a change in per share net asset value
from $19.32 to $19.56, and assuming reinvestment of all distributions. By
comparison, the Fund's unmanaged benchmark, which is comprised 80% of the
Credit Suisse Leveraged Loan Index and 20% of the Credit Suisse High Yield
Index, posted a total return of +5.06% for the same 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. Both the leveraged loan market and
the high yield market posted positive returns in each month 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've 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?

The portfolio is very well diversified among industries and issuers and has
generally favored the higher-rated tier of the high yield spectrum. The Fund's
outperformance of its benchmark for the period is primarily attributed to its
use of leverage.


What changes were made to the portfolio 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 Fund
finished the period by making more extensive use of its leverage lines. (For a
complete explanation of the benefits and risks of leveraging, refer to page 6
of this report to shareholders.)



BLACKROCK FLOATING RATE 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 historical
lows and a new-issue calendar that is just beginning to satisfy the non-
investment grade investor.

By and large, borrowers continue to have access to strong liquidity, another
force keeping default rates low. Moreover, earnings are expected to grow
strongly over the near-term. In our view, with such conditions in place for
the bank loan market, investors appear encouraged and ready to support new
deals and further spread tightening in the sector.

The Benefits and Risks of Leveraging


BlackRock Floating Rate 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 the Preferred Stock)
may reduce the Common Stock's yield and negatively impact its 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.



Availability of Quarterly Schedule of Investments


The Fund files its complete schedule of portfolio holdings with the Securities
and Exchange Commission ("SEC") for the first and third quarters of each fiscal
year on Form N-Q. The Fund's Forms N-Q are available on the SEC's Web site at

BLACKROCK FLOATING RATE INCOME STRATEGIES FUND, INC.          FEBRUARY 28, 2007



Notes to Financial Statements (Unaudited)


1. Significant Accounting Policies:
BlackRock Floating Rate Income Strategies Fund, Inc. 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 FRA.

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

(b) Valuation of investments--Floating rate loans are valued in accordance
with guidelines established by the Fund's Board of Directors. As of October 2,
2006, floating rate loan interests are valued at the mean between the last
available bid prices from one or more brokers or dealers as obtained from Loan
Pricing Corporation. 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 floating rate loans for which no
reliable price quotes are available, such floating rate loans 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 a floating
rate loan, BlackRock Advisors, LLC (the "Manager") an indirect, wholly owned
subsidiary of BlackRock, Inc., will value the floating rate loan 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 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 markets, the last asked price. 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 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. 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.



BLACKROCK FLOATING RATE INCOME STRATEGIES FUND, INC.          FEBRUARY 28, 2007



Notes to Financial Statements (continued)


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 may 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. The
counterparty for certain instruments may pledge cash or securities as
collateral.

* 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.

* 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.

* 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 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.

(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.



BLACKROCK FLOATING RATE 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 trans-actions 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) 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.

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

(i) Recent accounting pronouncements--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. ("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. ("PNC"),
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.



BLACKROCK FLOATING RATE INCOME STRATEGIES FUND, INC.          FEBRUARY 28, 2007



Notes to Financial Statements (continued)


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 of .75% of the average daily value of the Fund's 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-Advisor 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 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.

For the six months ended February 28, 2007, the Fund reimbursed FAM and the
Manager $577 and $2,886, 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, 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.

Notes to Financial Statements (concluded)


6. Short-Term Borrowings:
On May 22, 2006, 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 $172,500,000.
Under the Citicorp program, the conduits will fund advances to the Fund
through the issuance of highly rated commercial paper. As security for its
obligations to the Lenders under the revolving securitization facility, the
Fund has granted a security interest in substantially all of its assets to and
in favor of the Lenders. The interest rate on the Fund's borrowings is based
on the interest rate carried by the commercial paper plus a program fee. The
Fund pays additional borrowing costs including a backstop commitment fee.

The weighted average annual interest rate was 5.63% and the average borrowing
was approximately $135,915,000 for the six months ended February 28, 2007.


7. Capital Loss Carryforward:

           (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 not beneficially own any stock issued by
                  the Fund.

Item 10 -  Submission of Matters to a Vote of Security Holders - Not Applicable

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.
