2 BLACKROCK FLOATING RATE INCOME STRATEGIES FUND II, INC. FEBRUARY 29, 2008

A Letter to Shareholders

Dear Shareholder

Financial markets weathered intense bouts of volatility in 2007, only to enter 2008 with no relief. January and February

proved to be trying months for equities, but strong ones for some areas of the bond market, as fears of an economic

recession swelled. The Federal Reserve Board (the “Fed”), after cutting the target federal funds rate 100 basis points

(1%) between September 2007 and year-end, more than matched those cuts in January alone. Responding to a slow-

ing economy and continued fallout from chaos in the credit markets, the Fed cut interest rates 75 basis points in a rare

unscheduled session on January 22, and followed with a 50-basis-point cut at its regular meeting on January 30.

Another 75-basis-point cut on March 18 brought the target rate to 2.25% .

Reverberations from the U.S. subprime mortgage collapse, and the associated liquidity and credit crisis, continue to per-

meate global financial markets. The S&P 500 Index of U.S. stocks was down in February, marking the fourth consecutive

month of negative returns. International markets, while not unscathed, generally have outperformed their U.S. counter-

parts so far in 2008. Emerging markets, benefiting from stronger economic growth rates, have done particularly well.

In fixed income markets, fears related to the economic slowdown and related credit crisis have led to a prolonged flight

to quality. Investors have largely shunned bonds associated with the housing and credit markets in favor of higher-quali-

ty government issues. The yield on 10-year Treasury issues, which touched 5.30% in June 2007 (its highest level in five

years), fell to 4.04% by year-end and to 3.53% by the end of February, while prices correspondingly rose. After setting

a new-issuance record in 2007, supply in the municipal bond market has been on the decline for four consecutive

months (measured year over year). The market has struggled with concerns around the creditworthiness of monoline

bond insurers and the failure of auctions for auction rate securities, driving yields higher and prices lower across the

curve. By period-end, municipal bonds were trading at higher yields than their Treasury counterparts, a very unusual

occurrence by historical standards.

Against this backdrop, the major benchmark indexes posted mixed results for the current reporting period, generally

reflecting heightened investor risk aversion:

Total Returns as of February 29, 2008	6-month		12-month
U.S. equities (S&P 500 Index)		–8.79%		–3.60%
Small cap U.S. equities (Russell 2000 Index)	–12.91		–12.44
International equities (MSCI Europe, Australasia, Far East Index)		–4.71		+0.84
Fixed income (Lehman Brothers U.S. Aggregate Bond Index)		+5.67		+7.30
Tax-exempt fixed income (Lehman Brothers Municipal Bond Index)		–0.60		–1.17
High yield bonds (Lehman Brothers U.S. Corporate High Yield 2% Issuer Cap Index)		–1.39		–3.08

Fund Summary as of February 29, 2008

Investment Objective

BlackRock Floating Rate Income Strategies Fund II, Inc. (FRB) seeks a high current income and such preservation of capital as is consistent with investment in a diversified, leveraged portfolio consisting primarily of floating rate debt securities and instruments.

Fund Performance

For the year ended February 29, 2008, the Fund returned –12.88% based on market price, with dividends reinvested. The Fund’s return based on net asset value (“NAV”) was –8.98%, with dividends reinvested. For the same period, the Lipper Loan Participation Funds category posted an average return of –9.82% on a NAV basis. Fund performance was hurt by the widening of credit spreads, lack of liquidity and massive deleveraging in the loan market. Additionally, the rapid reduction of short-term interest rates as a result of the Fed’s shift in monetary policy negatively affected the price of loan debt securities.

4 BLACKROCK FLOATING RATE INCOME STRATEGIES FUND II, INC. FEBRUARY 29, 2008

The Benefits and Risks of Leveraging

BlackRock Floating Rate Income Strategies Fund II, Inc. (the “Fund”)
utilizes leverage through borrowings or issuance of short-term debt
securities. 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 benefit from the incremental yield.

Leverage creates risks for Common Stock shareholders, including the
likelihood of greater NAV and market price volatility. In addition, there is
the risk that fluctuations in interest rates on borrowings may reduce the
Common Stock’s yield and negatively impact its NAV and market price. If
the income derived from securities purchased with assets received from
leverage exceeds the cost of leverage, the Fund’s net income will be
greater than if leverage had not been used. Conversely, if the income
from the securities purchased is not sufficient to cover the cost of lever-
age, 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.

Swap Agreements

The Fund may invest in swap agreements, which are over-the-counter
contracts in which one party agrees to make periodic payments based on
the change in market value of a specified bond, basket of bonds, or index
in return for periodic payments based on a fixed or variable interest rate
or the change in market value of a different bond, basket of bonds or
index. Swap agreements may be used to obtain exposure to a bond or

market without owning or taking physical custody of securities. Swap
agreements involve the risk that the party with whom the Fund has
entered into the swap will default on its obligation to pay the Fund and
the risk that the Fund will not be able to meet its obligations to pay the
other party to the agreement.

Notes to Financial Statements

1. Significant Accounting Policies:

BlackRock Floating Rate Income Strategies Fund II, Inc. (the “Fund”) is
registered under the Investment Company Act of 1940, as amended
(the “1940 Act”), as a diversified, closed-end management investment
company. The Fund’s financial statements are prepared in conformity
with accounting principles generally accepted in the United States of
America, which may require the use of management accruals and esti-
mates. Actual results may differ from these estimates. The Fund deter-
mines, and makes available for publication, the net asset value of its
Common Stock on a daily basis.

The following is a summary of significant accounting policies followed by
the Fund:

Valuation of Investments: The Fund values most of its corporate bond
investments on the basis of last available bid price or current market
quotations provided by dealers or pricing services selected under the
supervision of the Fund’s Board of Directors (the “Board”). In determin-
ing the value of a particular investment, pricing services may use certain
information with respect to transactions in such investments, quotations
from dealers, market transactions in comparable investments, various
relationships observed in the market between investments, and calculat-
ed yield measures based on valuation technology commonly employed
in the market for such investments.

Floating rate loans are valued in accordance with guidelines established
by the Board. Floating rate loan interests are valued at the mean
between the last available bid prices from one or more brokers or deal-
ers as obtained from Loan Pricing Corporation (“LPC”). For the limited
number of floating rate loans for which no reliable price quotes are avail-
able, such floating rate loans may be valued by LPC 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
“Advisor”), an indirect, wholly owned subsidiary of BlackRock, Inc., will
value the floating rate loan at fair value, which is intended to approxi-
mate market value.

Equity investments traded on a national securities exchange or on the
NASDAQ Global Market System are valued at the last reported sale
price that day or the NASDAQ official closing price, if applicable. Equity
investments traded on a national securities exchange for which there
were no sales on that day and equity investments traded on other over-
the-counter (“OTC”) markets for which market quotations are readily
available are valued at the last available bid price. Effective September
4, 2007, exchange-traded options are valued at the mean between the
last bid and asked prices at the close of the options market in which
the options trade and previously were valued at the last sales price as
of the close of options trading on applicable exchanges. OTC options
quotations are provided by dealers or pricing services selected under
the supervision of the Board. Considerations utilized by dealers or
pricing services in valuing OTC options include, but are not limited to,

volatility factors of the underlying security, price movement of the under-
lying security in relation to the strike price and the time left until expira-
tion of the option. Swap agreements are valued by quoted fair values
received daily by the Fund’s pricing service. Short-term securities may
be valued at amortized cost.

In the event that application of these methods of valuation results in a
price for an investment which is deemed not to be representative of the
market value of such investment, the investment will be valued by, under
the direction of, or in accordance with, a method approved by the Board
as reflecting fair value (“Fair Value Assets”). When determining the price
for Fair Value Assets, the Advisor and/or sub-advisor seeks to determine
the price that the Fund might reasonably expect to receive from the cur-
rent sale of that asset in an arm’s-length transaction. Fair value determi-
nations shall be based upon all available factors that the Advisor and/or
sub-advisor deems relevant. The pricing of all Fair Value Assets is sub-
sequently reported to the Board or a committee thereof.

Generally, trading in foreign securities is substantially completed each
day at various times prior to the close of business on the New York Stock
Exchange (“NYSE”). The values of such securities used in computing the
net assets of the Fund are determined as of such times. Foreign curren-
cy exchange rates will be determined as of the close of business on the
NYSE. Occasionally, events affecting the values of such securities and
such exchange rates may occur between the times at which they are
determined and the close of business on the NYSE that may not be
reflected in the computation of the Fund’s net assets. If events (for
example, a company announcement, market volatility or a natural disas-
ter) occur during such periods that are expected to materially affect the
value of such securities, those securities will be valued at their fair value
as determined in good faith by the Board or by the Advisor using a pric-
ing service and/or procedures approved by the Board.

Floating Rate Loans: The Fund invests in floating rate loans, which are
generally non-investment grade, made by banks, other financial institu-
tions and privately and publicly offered corporations. Floating rate loans
generally pay interest at rates that are periodically determined by refer-
ence to a base lending rate plus a premium. The base lending rates are
generally (i) the lending rate offered by one or more European banks,
such as LIBOR (London InterBank Offered Rate), (ii) the prime rate
offered by one or more U.S. banks or (iii) the certificate of deposit rate.
The Fund considers these investments to be investments in debt securi-
ties for purposes of its investment policies.

The Fund earns and/or pays facility and other fees on floating rate
loans. Other fees earned/paid include commitment, amendment, con-
sent, commissions and prepayment penalty fees. Facility, amendment
and consent fees are typically amortized as premium and/or accreted
as discount over the term of the loan. Commitment, commission and
various other fees are recorded as income. Prepayment penalty fees are
recorded as gains or losses. When the Fund buys a floating rate loan it

16 BLACKROCK FLOATING RATE INCOME STRATEGIES FUND II, INC. FEBRUARY 29, 2008

Notes to Financial Statements (continued)

may receive a facility fee and when it sells a floating rate loan it may pay
a facility fee. On an ongoing basis, the Fund may receive a commitment
fee based on the undrawn portion of the underlying line of credit portion
of a floating rate loan. In certain circumstances, the Fund may receive a
prepayment penalty fee upon the prepayment of a floating rate loan by
a borrower. Other fees received by the Fund may include covenant waiver
fees and covenant modification fees.

The Fund may invest in multiple series or tranches of a loan. A
different series or tranche may have varying terms and carry different
associated risks.

Floating rate loans are usually freely callable at the issuer’s option. The
Fund may invest in such loans in the form of participations in loans
(“Participations”) and assignments of all or a portion of loans from third
parties. Participations typically will result in the Fund having a contrac-
tual relationship only with the lender, not with the borrower. The Fund
will have the right to receive payments of principal, interest and any fees
to which it is entitled only from the lender selling the Participation and
only upon receipt by the lender of the payments from the borrower.

In connection with purchasing Participations, the Fund generally will
have no right to enforce compliance by the borrower with the terms of
the loan agreement relating to the loans, nor any rights of offset against
the borrower, and the Fund may not benefit directly from any collateral
supporting the loan in which it has purchased the Participation.

As a result, the Fund will assume the credit risk of both the borrower and
the lender that is selling the Participation. The Fund’s investments in loan
participation interests involve the risk of insolvency of the financial inter-
mediaries who are parties to the transactions. In the event of the insol-
vency of the lender selling the Participation, the Fund may be treated
as a general creditor of the lender and may not benefit from any offset
between the lender and the borrower.

Preferred Stock: The Fund may invest in preferred stocks. Preferred
stock has a preference over common stock in liquidation (and generally
in receiving dividends as well) but is subordinated to the liabilities of
the issuer in all respects. As a general rule, the market value of preferred
stock with a fixed dividend rate and no conversion element varies
inversely with interest rates and perceived credit risk, while the market
price of convertible preferred stock generally also reflects some element
of conversion value. Because preferred stock is junior to debt securities
and other obligations of the issuer, deterioration in the credit quality
of the issuer will cause greater changes in the value of a preferred
stock than in a more senior debt security with similar stated yield char-
acteristics. Unlike interest payments on debt securities, preferred stock
dividends are payable only if declared by the issuer’s board of directors.
Preferred stock also may be subject to optional or mandatory redemp-
tion provisions.

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

_{•Options — The Fund may purchase and write 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 lia-
bility. 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 received or paid). If an option is exercised, the premium
paid or received is added to the cost of the purchase or the pro-
ceeds from the sale in determining whether the Fund has realized a
gain or a loss on investment transactions.

A call option gives the purchaser of the option the right (but not the
obligation) to buy, and obligates the seller to sell (when the option is
exercised), the underlying position at the exercise price at any time
or at a specified time during the option period. A put option gives the
holder the right to sell and obligates the writer to buy the underlying
position at the exercise price at any time or at a specified time dur-
ing the option period.

_{•Credit Default Swaps — The Fund may invest in credit default swaps,}
which are OTC contracts in which one party pays fixed periodic pay-
ments to a counterparty in consideration for a guarantee from the
counterparty to make a specific payment should a negative credit
event take place. 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 arise from the possible inability of the counter-
parties to meet the terms of their contracts. The Fund is exposed
to credit loss in the event of non-performance by the other party to
the swap.

The Fund may utilize credit default swaps for the purpose of reducing
the interest rate sensitivity of the portfolio and decreasing the Fund’s
exposure to interest rate risk.

Notes to Financial Statements (continued)

Foreign Currency Transactions: Foreign currency amounts are translated
into United States dollars on the following basis: (i) market value of
investment securities, assets and liabilities at the current rate of exchange;
and (ii) purchases and sales of investment securities, income and
expenses at the rates of exchange prevailing on the respective dates
of such transactions.

The Fund reports foreign currency related transactions as components
of realized gains for financial reporting purposes, whereas such compo-
nents are treated as ordinary income for federal income tax purposes.

Income Taxes: It is the Fund’s policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment compa-
nies and to distribute substantially all of its taxable income to its share-
holders. Therefore, no federal income tax provision is required. Under the
applicable foreign tax laws, a withholding tax may be imposed on inter-
est, dividends and capital gains at various rates.

Effective August 31, 2007, the Fund implemented Financial Accounting
Standards Board (“FASB”) Interpretation No. 48, “Accounting for
Uncertainty in Income Taxes — an interpretation of FASB Statement No.
109” (“FIN 48”). 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, includ-
ing investment companies, before being measured and recognized in the
financial statements. The Advisor has evaluated the application of FIN 48
to the Fund, and has determined that the adoption of FIN 48 did not
have a material impact on the Fund’s financial statements. The Fund
files U.S. and various state and local tax returns. No income tax returns
are currently under examination. The statute of limitations on the Fund’s
U.S. federal tax return remains open for the years ended February 28,
2005 through February 28, 2007. The statutes of limitations on the
Fund’s state and local tax returns may remain open for an additional
year depending upon the jurisdiction.

Investment Transactions and Investment Income: Investment trans-
actions 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.

Dividends and Distributions: Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded
on the ex-dividend dates.

Recent Accounting Pronouncements: 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 frame-
work for measuring fair value and expands disclosures about fair value
measurements. The impact on the Fund’s financial statement disclosure,
if any, is currently being assessed.

In addition, in February 2007, Statement of Financial Accounting
Standards No. 159, “The Fair Value Option for Financial Assets and
Financial Liabilities” (“FAS 159”), was issued and is effective for fiscal
years beginning after November 15, 2007. 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. The
impact on the Fund’s financial statement disclosures, if any, is currently
being assessed.

Segregation: In cases in which the 1940 Act and the interpretive posi-
tions of the Securities and Exchange Commission (“SEC”) require that
the Fund segregate assets in connection with certain investments
(e.g., swaps), the Fund will, consistent with certain interpretive letters
issued by the SEC, designate on its books and records cash or other liq-
uid debt securities having a market value at least equal to the amount
that would otherwise be required to be physically segregated.

Deferred Compensation and BlackRock Closed-End Share Equivalent
Investment Plan: Under the deferred compensation plan approved by
the Fund’s Board, non-interested directors (“Independent Directors”)
defer a portion of their annual complex-wide compensation. Deferred
amounts earn an approximate return as though equivalent dollar
amounts had been invested in common shares of other certain
BlackRock Closed-End Funds selected by the Independent Directors.
This has approximately the same economic effect for the Independent
Directors as if the Independent Directors had invested the deferred
amounts directly in other certain BlackRock Closed-End Funds.

The deferred compensation plan is not funded and obligations thereunder
represent general unsecured claims against the general assets of the
Fund. Each Fund may, however, elect to invest in common shares of
other certain BlackRock Closed-End Funds selected by the Independent
Directors in order to match its deferred compensation obligations.
Investments to cover the Fund’s deferred compensation liability are
included in other assets on the Statement of Assets and Liabilities.

Other: Expenses that are directly related to one of the Funds are
charged to that Fund. Other operating expenses are pro-rated to certain
Funds on the basis of relative net assets.

2. Investment Advisory Agreement and Other Transactions
with Affiliates:

The Fund has entered into an Investment Advisory Agreement with the
Advisor to provide investment advisory and administration services.
Merrill Lynch & Co., Inc. (“Merrill Lynch”) and The PNC Financial Services
Group, Inc. are principal owners of BlackRock, Inc.

The Advisor 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 the Advisor a monthly fee at an annual rate of 0.75% of
the average daily value of the Fund’s net assets plus the proceeds of
any outstanding borrowings used for leverage. In addition, the Advisor
has entered into a separate sub-advisory agreement with BlackRock
Financial Management, Inc. (“BFM”), an affiliate of the Advisor, under
which the Advisor pays BFM for services it provides, a monthly fee that
is a percentage of the management fee paid by the Fund to the Advisor.
For the year ended February 29, 2008, the Fund reimbursed the Advisor
$3,482 for certain accounting services, which is included in accounting
services expenses in the Statement of Operations, were $3,482.

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 29, 2008 were
$157,610,932 and $157,997,334, respectively.

4. Capital Stock Transactions:

The Fund is authorized to issue 200,000,000 shares of capital stock,
par value $0.10 per share, all of which are initially classified as
Common Stock. The Board is authorized, however, to classify and
reclassify any unissued shares of capital stock without approval of
the holders of Common Stock.

Shares issued and outstanding during the years ended February 29,
2008 and February 28, 2007 remained constant.

5. Commitments:

The Fund may invest in floating rate loans. In connection with these
investments, the Fund may, with its Advisor, also enter into unfunded
corporate loans (“commitments”). Commitments may obligate the Fund
to furnish temporary financing to a borrower until permanent financing
can be arranged. At February 29, 2008, the Fund had outstanding
commitments of approximately $6,654,000. In connection with these
commitments, the Fund earns a commitment fee, typically set as a
percentage of the commitment amount. Such fee income, which is

classified in the Statement of Operations as facility and other fees, is
recognized ratably over the commitment period. As of February 29,
2008, the Fund had the following unfunded loan commitments:

6. Short-Term Borrowings:

The Fund is a party to a 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”). On
May 16, 2007, the agreement was renewed for one year and has a max-
imum limit of $100,000,000. Under the Citicorp administered program,
the conduits will fund advances to the Fund through highly rated com-
mercial paper. The Fund has granted a security interest in substantially
all of its assets to, and in favor of, the Lenders as security for its obliga-
tions to the Lenders. The interest rate on the Fund borrowings is based
on the interest rate carried by the commercial paper plus a program fee.
In addition, the Fund pays a liquidity fee to the secondary backstop
lenders and the agent. The weighted average annual interest rate was
5.49% for the year ended February 29, 2008.

7. Distributions to Shareholders:

No provision is made for U.S. federal income taxes as it is the Fund’s
intention to continue to qualify for and elect the tax treatment applicable
to regulated investment companies under Subchapter M of the Internal
Revenue Code of 1986, as amended, and to make the requisite distribu-
tions to their respective shareholders, which will be sufficient to relieve
them from federal income and excise taxes.

Reclassification: U.S. generally accepted accounting principles require
that certain components of net assets be adjusted to reflect permanent
differences between financial and tax reporting. Accordingly, during the
current year, $237,109 has been reclassified between undistributed net
investment income and accumulated net realized capital losses as a
result of permanent differences attributable to foreign currency trans-
actions and accounting for swap agreements. This reclassification has
no effect on net assets or net asset values per share.

Notes to Financial Statements (concluded)

The tax character of distributions paid during the fiscal years ended
February 29, 2008 and February 28, 2007 was as follows:

	2/29/2008	2/28/2007
Distributions paid from:
Ordinary income	$ 15,779,101	$16,114,520
Total taxable distributions	$ 15,779,101	$16,114,520

As of February 29, 2008, the components of accumulated losses on a tax
basis were as follows:

Undistributed net ordinary income	$ 2,090,101
Undistributed net long-term capital gains	—
Total net undistributed earnings	2,090,101
Capital loss carryforward	(1,519,783)
Net unrealized losses	(32,186,932)*
Total net accumulated losses	$ (31,616,614)

*

On February 29, 2008, the Fund had a net capital loss carryforward of $1,519,783, of which $203,838 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 losses is attributa- ble primarily to the tax deferral of losses on wash sales, the difference between book and tax amortization methods for premiums and discounts on fixed income securities, book/tax differences in the accrual of income on securities in default, the realization for tax purposes of unrealized gains (losses) on certain foreign cur- rency contracts, the deferral of post-October capital losses for tax purposes and accounting for swap agreements.

8. Subsequent Event:

The Fund paid a net investment income dividend in the amount of
$0.123350 per share on March 31, 2008 to shareholders of record
on March 14, 2008.

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 and liabilities
of BlackRock Floating Rate Income Strategies Fund II, Inc. (the “Fund”),
including the schedule of investments as of February 29, 2008, and
the related statements of operations and cash flows for the year then
ended, the statements of changes in net assets for each of the two
years in the period then ended, and the financial highlights for the
periods presented. 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 high-
lights 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 assur-
ance 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 finan-
cial 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 finan-

cial 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 pro-
cedures included confirmation of securities owned as of February 29,
2008, by correspondence with the custodian and financial interme-
diaries; where replies were not received, 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 29, 2008, 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 the financial highlights for the
periods presented, 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 esti-
mated brokerage commissions (a condition often referred to as a “mar-
ket 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 dis-
count”), 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 dis-
count 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 pur-
chased 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 pur-
chases 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 to the right) that they elect
not to participate in the Plan. Participation in the Plan is completely vol-
untary 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 partici-
pating in the Plan. The Plan Agent’s service fees for handling the rein-
vestment 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 distribu-
tions 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. Participation in the Plan generally will
not affect the tax-exempt status of exempt interest dividends paid by the
Fund. 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 por-
tion 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, includ-
ing any questions about the Plan, should be directed to the Plan Agent
at Computershare Trust Company, N.A., .O. Box 43010, Providence, RI
02940-3010, Telephone: (800) 426-5523.

General Information

The Fund does not make available copies of its Statements of Additional
Information because the Fund’s shares are not continuously offered,
which means that the Statement of Additional Information of the Fund
has not been updated after completion of the Fund’s offering and the
information contained in the Fund’s Statement of Additional Information
may have become outdated.

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

During the period, there were no material changes in the Fund’s invest-
ment objective or policies or to the Fund’s character or by-laws that were
not approved by the shareholders or in the principal risk factors associ-
ated with investment in the Fund. There have been no changes in the
persons who are primarily responsible for the day-to-day management of
the Fund’s portfolios.

mation regarding the Fund may be found on BlackRock’s website, which

Item 2 – Code of Ethics – The registrant (or the “Fund”) has adopted a code of ethics, as of the end
of the period covered by this report, applicable to the registrant's principal executive officer,
principal financial officer and principal accounting officer, or persons performing similar
functions. During the period covered by this report, there have been no amendments to or
waivers granted under the code of ethics. A copy of the code of ethics is available without

Item 3 – Audit Committee Financial Expert – The registrant's board of directors or trustees, as
applicable (the “board of directors”) has determined that (i) the registrant has the following
audit committee financial experts serving on its audit committee and (ii) each audit
committee financial expert is independent:
Kent Dixon (term began effective November 1, 2007)
Frank J. Fabozzi (term began effective November 1, 2007)
James T. Flynn (term began effective November 1, 2007)
Ronald W. Forbes (term ended effective November 1, 2007)
W. Carl Kester (term began effective November 1, 2007)
Karen P. Robards (term began effective November 1, 2007)
Robert S. Salomon, Jr. (term began effective November 1, 2007)
Richard R. West (term ended effective November 1, 2007)

The registrant's board of directors has determined that W. Carl Kester and Karen P. Robards
qualify as financial experts pursuant to Item 3(c)(4) of Form N-CSR.

Prof. Kester has a thorough understanding of generally accepted accounting principles,
financial statements and internal control over financial reporting as well as audit committee
functions. Prof. Kester has been involved in providing valuation and other financial
consulting services to corporate clients since 1978. Prof. Kester’s financial consulting
services present a breadth and level of complexity of accounting issues that are generally
comparable to the breadth and complexity of issues that can reasonably be expected to be
raised by the registrant’s financial statements.

Ms. Robards has a thorough understanding of generally accepted accounting principles,
financial statements and internal control over financial reporting as well as audit committee
functions. Ms. Robards has been President of Robards & Company, a financial advisory
firm, since 1987. Ms. Robards was formerly an investment banker for more than 10 years
where she was responsible for evaluating and assessing the performance of companies based
on their financial results. Ms. Robards has over 30 years of experience analyzing financial
statements. She also is a member of the audit committee of one publicly held company and
a non-profit organization.

Under applicable securities laws, a person determined to be an audit committee financial
expert will not be deemed an “expert” for any purpose, including without limitation for the
purposes of Section 11 of the Securities Act of 1933, as a result of being designated or
identified as an audit committee financial expert. The designation or identification as an
audit committee financial expert does not impose on such person any duties, obligations, or
liabilities greater than the duties, obligations, and liabilities imposed on such person as a
member of the audit committee and board of directors in the absence of such designation or
identification.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:
The registrant’s audit committee (the “Committee”) has adopted policies and
procedures with regard to the pre-approval of services. Audit, audit-related and tax
compliance services provided to the registrant on an annual basis require specific pre-
approval by the Committee. The Committee also must approve other non-audit services
provided to the registrant and those non-audit services provided to the registrant’s affiliated
service providers that relate directly to the operations and the financial reporting of the
registrant. Certain of these non-audit services that the Committee believes are a) consistent
with the SEC’s auditor independence rules and b) routine and recurring services that will
not impair the independence of the independent accountants may be approved by the
Committee without consideration on a specific case-by-case basis (“general pre-approval”).
The term of any general pre-approval is 12 months from the date of the pre-approval, unless
the Committee provides for a different period. Tax or other non-audit services provided to
the registrant which have a direct impact on the operation or financial reporting of the
registrant will only be deemed pre-approved provided that any individual project does not
exceed $10,000 attributable to the registrant or $50,000 for all of the registrants the
Committee oversees. For this purpose, multiple projects will be aggregated to determine if
they exceed the previously mentioned cost levels.
Any proposed services exceeding the pre-approved cost levels will require specific
pre-approval by the Committee, as will any other services not subject to general pre-
approval (e.g., unanticipated but permissible services). The Committee is informed of each
service approved subject to general pre-approval at the next regularly scheduled in-person
board meeting. At this meeting, an analysis of such services is presented to the Committee
for ratification. The Committee may delegate to one or more of its members the authority to
approve the provision of and fees for any specific engagement of permitted non-audit
services, including services exceeding pre-approved cost levels.

(e)(2) None of the services described in each of Items 4(b) through (d) were approved by
the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(h) The registrant’s audit committee has considered and determined that the provision of
non-audit services that were rendered to the registrant’s investment adviser (not including
any non-affiliated sub-adviser whose role is primarily portfolio management and is
subcontracted with or overseen by the registrant’s investment adviser), and any entity
controlling, controlled by, or under common control with the investment adviser that
provides ongoing services to the registrant that were not pre-approved pursuant to paragraph
(c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant’s independence.

Item 8 – Portfolio Managers of Closed-End Management Investment Companies – as of February 29,
2008.

(a)(1) BlackRock Floating Rate Strategies II, Inc. is managed by a team of investment
professionals comprised of Mark J. Williams, Managing Director at BlackRock and Kevin J.
Booth, CFA, Managing Director at BlackRock. Each is a member of BlackRock’s fixed
income portfolio management group. Mr. Williams is responsible for setting overall
investment strategy and overseeing management of the Fund. Mr. Booth is responsible for
the day-to-day management of the Fund’s portfolio and the selection of its investments.
Messrs. Booth and Williams have been members of the Fund’s management team since
2006.

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.

Kevin Booth is co-head of the high yield team within BlackRock’s Fixed Income Portfolio
Management Group. His primary responsibilities are managing portfolios and directing
investment strategy. He specializes in hybrid high yield portfolios, consisting of leveraged
bank loans, high yield bonds, and distressed obligations. Prior to joining BlackRock, Mr.
Booth was a Managing Director (Global Fixed Income) of Merrill Lynch Investment
Managers (“MLIM”) in 2006, a Director from 1998 to 2006 and was a Vice President of
MLIM from 1991 to 1998. He has been a portfolio manager with BlackRock or MLIM since

(iv) Potential Material Conflicts of Interest

BlackRock, Inc. and its affiliates (collectively, herein “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, including Messrs. Booth and Williams,
currently manage certain accounts that are subject to performance fees. In addition, certain
portfolio managers may 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 29, 2008:

Portfolio Manager Compensation Overview

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 performance-based 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. Senior portfolio managers who perform
additional management functions within the portfolio management group or within
BlackRock may receive additional compensation for serving in these other capacities.

Discretionary Incentive Compensation

Discretionary incentive compensation 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, of the firm’s assets under
management or supervision by that portfolio manager relative to predetermined
benchmarks, and the individual’s seniority, role within the portfolio management team,
teamwork and contribution to the overall performance of these portfolios and BlackRock.
In most cases, including for the portfolio managers of the Fund, these benchmarks are the
same as the benchmark or benchmarks against which the performance of the Fund or other
accounts managed by the portfolio managers are measured. BlackRock’s Chief Investment
Officers determine the benchmarks against which the performance of funds and other
accounts managed by each portfolio manager is compared and the period of time over which
performance is evaluated. With respect to the portfolio managers, such benchmarks include
the following:

Portfolio Manager	Applicable Benchmarks
Kevin Booth	A combination of market-based indices (e.g., The Lehman Brothers
	U.S. Corporate High Yield 2% Issuer Cap Index), certain
	customized indices and certain fund industry peer groups.
Mark Williams	A combination of market-based indices (e.g., Credit Suisse
	Leveraged Loan Index, LIBOR), certain customized indices and
	certain fund industry peer groups.

BlackRock’s Chief Investment Officers make a subjective determination with respect to the
portfolio managers’ compensation based on the performance of the funds and other accounts
managed by each portfolio manager relative to the various benchmarks noted above.
Performance is measured on both a pre-tax and after-tax basis over various time periods
including 1, 3, 5 and 10-year periods, as applicable.

Distribution of Discretionary Incentive Compensation
Discretionary incentive compensation is distributed to portfolio managers in a combination
of cash and BlackRock, Inc. restricted stock units which vest ratably over a number of
years. The BlackRock, Inc. restricted stock units, if properly vested, will be settled in
BlackRock, Inc. common stock. Typically, the cash bonus, when combined with base
salary, represents more than 60% of total compensation for the portfolio managers. Paying
a portion of annual bonuses in stock puts compensation earned by a portfolio manager for a
given year “at risk” based on the Company’s ability to sustain and improve its performance
over future periods.

Other compensation benefits. In addition to base compensation and discretionary
incentive compensation, portfolio managers may be eligible to receive or participate in 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. Prior to 2006, the plan provided
for the grant of awards that were 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. Beginning in 2006, awards are granted under the LTIP in
the form of BlackRock, Inc. restricted stock units that, if properly vested and subject to the
attainment of certain performance goals, will be settled in BlackRock, Inc. common stock.
Each portfolio manager has received awards under the LTIP.

Deferred Compensation Program —A portion of the compensation paid to eligible
BlackRock employees may be voluntarily deferred into an account that tracks the
performance of certain of the firm’s investment products. Each participant in the deferred
compensation program is permitted to allocate his deferred amounts among various options,
including to certain of the firm’s hedge funds and other proprietary mutual funds. Each
portfolio manager has participated in the deferred compensation program.

Options and Restricted Stock Awards — A portion of the annual compensation of
certain employees is mandatorily deferred into BlackRock restricted stock units. Prior to the
mandatory deferral into restricted stock units, the Company granted stock options to key
employees, including certain portfolio managers who may still hold unexercised or unvested
options. BlackRock, Inc. also granted restricted stock awards 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. Mr. Williams has been granted stock options and/or
restricted stock in prior 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 balanced portfolio. 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.

(a)(4) Beneficial Ownership of Securities. As of February 29, 2008, the portfolio
managers beneficially owned stock issued by the Fund in the ranges set forth below:

Portfolio Manager	Dollar Range
Kevin Booth	$10,001 to $50,000
