The Benefits and Risks of Leveraging


BlackRock Floating Rate Income Strategies Fund II, 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.



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 stock
holders 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
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.

A Discussion With Your Fund's Portfolio Managers


Fund performance during the fiscal year benefited most from our use of
leverage in what was a relatively strong period for non-investment grade
markets.


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

For the 12-month period ended February 28, 2007, the Common Stock of BlackRock
Floating Rate Income Strategies Fund II, Inc. had net annualized yields of
8.03% and 8.37%, based on a year-end per share net asset value of $19.28 and a
per share market price of $18.50, respectively, and $1.548 per share income
dividends. For the same period, the total investment return on the Fund's
Common Stock was +8.31%, based on a change in per share net asset value from
$19.39 to $19.28, and assuming reinvestment of all distributions. 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, returned +8.52% for
the 12-month period.

For the six-month period ended February 28, 2007, the total investment return
on the Fund's Common Stock was +5.20%, based on a change in per share net
asset value from $19.23 to $19.28, and assuming reinvestment of all
distributions. The composite benchmark returned +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 dividends, 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 +7.57% for the annual period, while the high yield bond
market, as measured by the Credit Suisse High Yield Index, returned +12.36%.
Despite some volatility late in the reporting period, the non-investment grade
markets continued to post strong results. The leveraged loan market posted
positive returns in all of the past 12 months, while the high yield market saw
positive returns in 11 of the past 12 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. In the
first half of the fiscal period, prior to the combination of Merrill Lynch
Investment Managers and BlackRock, the Fund had a fairly high cash position,
made relatively low use of leverage and was more conservatively positioned
versus the bank loan and high yield markets in general. The conservative
positioning early in the period hindered performance. The Fund later increased
its use of leverage, reduced its cash position and has been positioned more in
line with the representative bank loan and high yield markets, and this has
benefited performance amid the markets' strength.



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



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 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 2
of this report to shareholders.)

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.

 ** Floating rate loan interests in which the Fund invests generally pay
    interest at rates that are periodically redetermined by reference to a
    base lending rate plus a premium.  The base lending rates are generally

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



Notes to Financial Statements


1. Significant Accounting Policies:
On September 29, 2006, Floating Rate Income Strategies Fund II, Inc. was
renamed BlackRock Floating Rate Income Strategies Fund II, 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 FRB.

(a) Corporate debt obligations--The Fund invests principally in floating rate
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 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 market, the last asked price. Options purchased are valued at the
last sale price in the case of exchange traded options or, in the case of
options traded in the OTC market, 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 financial 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.



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



Notes to Financial Statements (continued)


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 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.

* 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.



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



Notes to Financial Statements (continued)


(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. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.

(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) 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 Standard 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") and its affiliates, 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 the Manager. 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
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-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 and 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 year ended February 28, 2007, the Fund reimbursed FAM and the Manager
$2,617 and $1,615, respectively, for certain accounting services.

Prior to September 29, 2006, certain officers and/or directors of the Fund
were officers and/or directors of MLIM, FAM, 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.


3. Investments:
Purchases and sales (including paydowns) of investments, excluding short-term
securities, for the year ended February 28, 2007 were $167,864,547 and
$183,718,823, respectively.


4. Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of capital stock, par value
$.10 per share, all of which are 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.


5. Unfunded Loan Commitments:
As of February 28, 2007, the Fund had unfunded loan commitments of
approximately $17,231,000, which would be extended at the option of the
borrower pursuant to the following loan agreements:

                                                         (in Thousands)

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 $100,000,000.
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.

The weighted average annual interest rate was 5.48% and the average borrowing
was approximately $61,022,000 for the year ended February 28, 2007.

The tax character of distributions paid during the fiscal years ended February

  * On February 28, 2007, the Fund had a net capital loss carryforward
    of $1,783,719, of which $467,774 expires in 2014 and $1,315,945
    expires in 2015. 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 accounting treatment of
    swap payments.

Report of Independent Registered Public Accounting Firm


To the Shareholders and Board of Directors of
BlackRock Floating Rate Income Strategies Fund II, Inc.:

We have audited the accompanying statement of assets, liabilities and capital,
including the schedule of investments, of BlackRock Floating Rate Income
Strategies Fund II, Inc. (formerly Floating Rate Income Strategies Fund II,
Inc.) as of February 28, 2007, 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 the respective periods 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 February 28, 2007,
by correspondence with the custodian and financial intermediaries; where
replies were not received from financial intermediaries, 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 Floating Rate Income Strategies Fund II, Inc. as of February 28,
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 the respective periods 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: 800-426-5523.

           (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

           believes are a) consistent with the SEC's auditor independence rules

           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.

Item 7 -   Disclosure of Proxy Voting Policies and Procedures for Closed-End
           Management Investment Companies -
           Proxy Voting Policies and Procedures
           ------------------------------------

           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:

           * 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.

           * 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.

           * 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.

           * 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.

           * 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.

           * Routine proposals related to requests regarding the formalities of
           corporate meetings.

           * 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.

           * 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.

Item 8 -   Portfolio Managers of Closed-End Management Investment Companies -
           as of February 28, 2007.

           (a)(1) The Fund is managed by a team of investment professionals
           that is responsible for the day-to-day management of the Fund's
           portfolio.  The lead members of this team are Mark J. Williams,
           Managing Director at BlackRock, and Kevin J. Booth, Managing
           Director at BlackRock. Mr. Williams and Mr. Booth each has been a
           portfolio manager of the Fund since 2006.  Mr. Williams is
           responsible for setting the Fund's overall investment strategy and
           overseeing the management of the Fund as of October 2, 2006.  Mr.
           Booth is responsible for the day-to-day management of the Fund's
           portfolio and the selection of its investments.

           Mr. Williams is the head of BlackRock's bank loan group and a member
           of the Investment Strategy Group. His primary responsibility is
           originating and evaluating bank loan investments for the firm's
           collateralized bond obligations. He is also involved in the
           evaluation and sourcing of mezzanine investments. Prior to joining
           BlackRock in 1998, Mr. Williams spent eight years with PNC Bank's
           New York office and was a 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. Williams worked in PNC Bank's Philadelphia office in
           a variety of marketing and corporate finance positions.

           Mr. Booth is a member of BlackRock's bank loan group.  He joined
           BlackRock in 2006.  Prior to joining BlackRock, Mr. Booth was a
           Managing Director (Global Fixed Income) of Merrill Lynch Investment
           Managers, L.P. ("MLIM") since 2006 and a member of MLIM's bank loan
           group from 2000 to 2006. He was a Director of MLIM from 2000 to 2006
           and was a Vice President of MLIM from 1994 to 2000.  He has been
           portfolio manager with BlackRock or MLIM since 2000.

           (a)(2) As of February 28, 2007:




                                                                         (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,
                 Messrs. Booth and Williams do not beneficially own 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 - 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.
