JANUARY 31, 2009

A Letter to Shareholders

Dear Shareholder

The present time may well be remembered as one of the most tumultuous periods in financial market history. Over the past year, the bursting of the

housing bubble and the resultant credit crisis swelled into an all-out global financial market meltdown that featured the collapse of storied financial

firms, volatile swings in the world’s financial markets and monumental government responses, including the nearly $800 billion economic stimulus

plan signed into law just after period end.

The US economy appeared relatively resilient through the first few months of 2008, when rising food and energy prices fueled inflation fears. Mid-

summer ushered in dramatic changes- inflationary pressure subsided amid a plunge in commodity prices, while economic pressures intensified in the

midst of a rapid deterioration in consumer spending, employment and other key indicators. By year’s end, the National Bureau of Economic Research

affirmed that the United States was in a recession, which officially began in December 2007. The Federal Reserve Board (the “Fed”), after slashing

interest rates aggressively early in the period, resumed that rate-cutting campaign in the fall, with the final reduction in December 2008 bringing the

target federal funds rate to a record low range of between zero and 0.25% . Importantly, the central bank pledged that future policy moves to revive the

global economy and financial markets would comprise primarily nontraditional and quantitative easing measures, such as capital injections, lending

programs and government guarantees.

Against this backdrop, US equity markets experienced intense volatility, with the sentiment turning decisively negative toward period end. Declines were

significant and broad-based, with little divergence among large- and small-cap stocks. Non-US stocks posted stronger results early on, but quickly lost

ground as the credit crisis revealed itself to be global in scope and as the worldwide economic slowdown gathered pace. Overall, aggressive monetary

and fiscal policy, combined with the defensiveness of the US, helped domestic equities notch better performance than their non-US counterparts.

In fixed income markets, risk aversion remained the popular theme, leading the Treasury sector to top all other asset classes. The high yield market

was particularly hard hit in this environment, as economic turmoil, combined with frozen credit markets and substantial technical pressures, took a

heavy toll. Meanwhile, the municipal bond market was challenged by a dearth of market participants, lack of liquidity, difficult funding environment and

backlog of new-issue supply, which sent prices lower and yields well above Treasuries. By period end, however, some positive momentum had returned

to the municipal space.

In all, an investor flight to safety prevailed, as evidenced in the six- and 12-month returns of the major benchmark indexes:

Fund Summary as of January 31, 2009

Investment Objective

BlackRock MuniHoldings Fund II, Inc. (MUH) (the “Fund”) seeks to provide shareholders with current income exempt from federal income taxes by
investing primarily in a portfolio of long-term, investment grade municipal obligations the interest on which, in the opinion of bond counsel to the
issuer, is exempt from federal income taxes.

Performance

For the six months ended January 31, 2009, the Fund returned (13.09)% based on market price and (8.95)% based on net asset value (NAV). For the
same period, the closed-end Lipper General Municipal Debt Leveraged Funds category posted an average return of (12.07)% on a market price basis
and (12.78)% on a NAV basis. All returns reflect reinvestment of dividends. The Fund’s discount to NAV, which widened during the period, accounts for
the difference between performance based on price and performance based on NAV. Fund performance was positively impacted by three factors: an
up-in-quality bias amid a widening in credit spreads; an emphasis on pre-refunded securities, which outperformed in the steepening yield curve envi-
ronment; and, a competitive dividend yield. With credit spreads at historically cheap levels, we anticipate allocating a larger exposure to the lower end
of the credit spectrum as a means to sustain an above-average yield ranking within the Fund’s peer group.

The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions.

These views are not intended to be a forecast of future events and are no guarantee of future results.

The Benefits and Risks of Leveraging

The Fund may utilize leverage to seek to enhance the yield and NAV of
its Common Shares. However, these objectives cannot be achieved in all
interest rate environments.

To leverage, the Fund issues Preferred Shares, which pay dividends at pre-
vailing short-term interest rates, and invests the proceeds in long-term
municipal bonds. In general, 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 Shareholders will benefit from the incremental yield.

To illustrate these concepts, assume the Fund’s Common Shares capital-
ization is $100 million and it issues Preferred Shares for an additional
$50 million, creating a total value of $150 million available for investment
in long-term municipal bonds. If prevailing short-term interest rates are
3% and long-term interest rates are 6%, the yield curve has a strongly
positive slope. In this case, the Fund pays dividends on the $50 million of
Preferred Shares based on the lower short-term interest rates. At the same
time, the Fund’s total portfolio of $150 million earns the income based
on long-term interest rates. In this case, the dividends paid to Preferred
Shareholders are significantly lower than the income earned on the Fund’s
long-term investments, and therefore the Common Shareholders are the
beneficiaries of the incremental yield.

Conversely, if prevailing short-term interest rates rise above long-term
interest rates of 6%, the yield curve has a negative slope. In this case, the
Fund pays dividends on the higher short-term interest rates whereas the
Fund’s total portfolio earns income based on lower long-term interest
rates. If short-term interest rates rise, narrowing the differential between
short-term and long-term interest rates, the incremental yield pickup on
the Common Shares will be reduced or eliminated completely.

Furthermore, the value of the Fund’s portfolio investments generally varies
inversely with the direction of long-term interest rates, although other
factors can influence the value of portfolio investments. In contrast, the
redemption value of the Fund’s Preferred Shares does not fluctuate in
relation to interest rates. As a result, changes in interest rates can influ-
ence the Fund’s NAV positively or negatively in addition to the impact on
Fund performance from leverage from Preferred Shares discussed above.

The Fund may also, from time to time, leverage its assets through the use
of tender option bond (“TOB”) programs, as described in Note 1 of the
Notes to Financial Statements. TOB investments generally will provide the
Fund with economic benefits in periods of declining short-term interest
rates, but expose the Fund to risks during periods of rising short-term
interest rates similar to those associated with Preferred Shares issued by
the Fund, as described above. Additionally, fluctuations in the market
value of municipal bonds deposited into the TOB trust may adversely
affect the Fund’s NAV per share.

The use of leverage may enhance opportunities for increased returns to
the Fund and Common Shareholders, but as described above, it also
creates risks as short- or long-term interest rates fluctuate. Leverage also
will generally cause greater changes in a Fund’s NAV, market price and
dividend rate than a comparable portfolio without leverage. 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 shareholders will be reduced. The
Fund may be required to sell portfolio securities at inopportune times or
below fair market values in order to comply with regulatory requirements
applicable to the use of leverage or as required by the terms of leverage
instruments, which may cause the Fund to incur losses. The use of lever-
age may limit the Fund’s ability to invest in certain types of securities or
use certain types of hedging strategies, such as in the case of certain
restrictions imposed by ratings agencies that rate preferred shares issued
by a fund. The Fund will incur expenses in connection with the use of
leverage, all of which are borne by the holders of the Common Shares
and may reduce returns on the Common Shares.

Under the Investment Company Act of 1940, the Fund is permitted to
issue Preferred Shares in an amount of up to 50% of its total managed
assets at the time of issuance. Under normal circumstances, the Fund
anticipates that the total economic leverage from Preferred Shares
and TOBs will not exceed 50% of its total managed assets at the time
such leverage is incurred. As of January 31, 2009, the Fund had eco-
nomic leverage from Preferred Shares and TOBs of 38% of its total
managed assets.

•Effective August 1, 2008, the Fund adopted Financial Accounting Standards
Board Statement of Financial Accounting Standards No. 157, “Fair Value
Measurements” (“FAS 157”). FAS 157 clarifies the definition of fair value, estab-
lishes a framework for measuring fair values and requires additional disclosures
about the use of fair value measurements. Various inputs are used in determining
the fair value of investments, which are as follows:
•Level 1 — price quotations in active markets/exchanges for identical securities
•Level 2 — other observable inputs (including, but not limited to: quoted prices
for similar assets or liabilities in markets that are not active, inputs other than
quoted prices that are observable for the assets or liabilities (such as interest
rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks
and default rates) or other market—corroborated inputs)
•Level 3 — unobservable inputs based on the best information available in the
circumstance, to the extent observable inputs are not available (including the
Fund’s own assumption used in determining the fair value of investments)
The inputs or methodology used for valuing securities are not necessarily an indi-
cation of the risk associated with investing in those securities. For information
about the Fund’s policy regarding valuation of investments and other significant
accounting policies, please refer to Note 1 of the Notes to Financial Statements.
The following table summarizes the inputs used as of January 31, 2009 in deter-
mining the fair valuation of the Fund’s investments:

Notes to Financial Statements (Unaudited)

1. Organization and Significant Accounting Policies:

BlackRock MuniHoldings Fund II, Inc. (the “Fund”) is registered under the
Investment Company Act of 1940, as amended (the “1940 Act”), as a
non-diversified, closed-end management investment company. The Fund
is organized as a Maryland corporation. 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 manage-
ment accruals and estimates. Actual results may differ from these esti-
mates. The Fund determines and makes available for publication the net
asset value of its Common Shares on a daily basis.

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

Valuation of Investments: Municipal investments (including commit-
ments to purchase such investments on a “when-issued” basis) are val-
ued on the basis of prices provided by dealers or pricing services select-
ed under the supervision of the Fund’s Board of Directors (the “Board”).
In determining the value of a particular investment, pricing services may
use certain information with respect to transactions in such investments,
quotations from dealers, pricing matrixes, market transactions in compa-
rable investments and information with respect to various relationships
between investments. Short-term securities with maturities less than
60 days are valued at amortized cost, which approximates fair value.
Investments in open-end investment companies are valued at net
asset value each business day.

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
a method approved by the Board as reflecting fair value (“Fair Value
Assets”). When determining the price for Fair Value Assets, the invest-
ment advisor and/or sub-advisor seeks to determine the price that the
Fund might reasonably expect to receive from the current sale of that
asset in an arm’s-length transaction. Fair value determinations shall
be based upon all available factors that the investment 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.

Forward Commitments and When-Issued Delayed Delivery Securities:
The Fund may purchase securities on a when-issued basis and may
purchase or sell securities on a forward commitment basis. Settlement
of such transactions normally occurs within a month or more after the
purchase or sale commitment is made. The Fund may purchase securi-
ties under such conditions only with the intention of actually acquiring
them, but may enter into a separate agreement to sell the securities
before the settlement date. Since the value of securities purchased may
fluctuate prior to settlement, the Fund may be required to pay more at
settlement than the security is worth. In addition, the purchaser is not
entitled to any of the interest earned prior to settlement. When purchas-
ing a security on a delay-delivering basis, the Fund assumes the rights

and risks of ownership of the security, including the risk of price and
yield fluctuations.

Municipal Bonds Transferred to Tender Option Bond Trusts: The Fund
leverages its assets through the use of tender option bonds trusts
(“TOBs”). A TOB is established by a third party sponsor forming a special
purpose entity, into which one or more funds, or an agent on behalf of
the funds, transfers municipal bonds. Other funds managed by the invest-
ment advisor may also contribute municipal bonds to a TOB into which
the Fund has contributed bonds. A TOB typically issues two classes of
beneficial interests: short-term floating rate certificates, which are sold to
third party investors, and residual certificates (“TOB Residuals”), which
are generally issued to the participating funds that made the transfer.
The TOB Residuals held by the Fund include the right of the Fund (1) to
cause the holders of a proportional share of the floating rate certificates
to tender their certificates at par, and (2) to transfer, within seven days, a
corresponding share of the municipal bonds from the TOB to the Fund.
The TOB may also be terminated without the consent of the Fund upon
the occurrence of certain events as defined in the TOB agreements. Such
termination events may include the bankruptcy or default of the munici-
pal bonds, a substantial downgrade in credit quality of the municipal
bonds, the inability of the TOB to obtain quarterly or annual renewal of
the liquidity support agreement, a substantial decline in market value of
the municipal bonds or the inability to remarket the short-term floating
rate certificates to third party investors.

The cash received by the TOB from the sale of the short-term floating
rate certificates, less transaction expenses, is paid to the Fund, which
typically invests the cash in additional municipal bonds. The Fund��s
transfer of the municipal bonds to a TOB is accounted for as a secured
borrowing, therefore the municipal bonds deposited into a TOB are pre-
sented in the Fund’s Schedule of Investments and the proceeds from
the issuance of the short-term floating rate certificates are shown on the
Statement of Assets and Liabilities as trust certificates.

Interest income from the underlying securities is recorded by the Fund
on an accrual basis. Interest expense incurred on the secured borrowing
and other expenses related to remarketing, administration and trustee
services to a TOB are reported as expenses of the Fund. The floating
rate certificates have interest rates that generally reset weekly and
their holders have the option to tender certificates to the TOB for
redemption at par at each reset date. As of January 31, 2009, the
aggregate value of the underlying municipal securities transferred to
TOBs was $37,752,717, the related liability for trust certificates was
$20,813,073 and the range of interest rates on trust certificates
was 1.940% – 3.390% .

Financial transactions executed through TOBs generally will underperform
the market for fixed rate municipal bonds when short-term interest rates
rise, but tend to outperform the market for fixed rate bonds when short-

16 BLACKROCK MUNIHOLDINGS FUND II, INC.

Notes to Financial Statements (continued)

term interest rates decline or remain relatively stable. Should short-term
interest rates rise, the Fund’s investment in TOBs may adversely affect
the Fund’s investment income and distributions to shareholders. Also,
fluctuations in the market value of municipal bonds deposited into the
TOB may adversely affect the Fund’s net asset values per share.

Zero-Coupon Bonds: The Fund may invest in zero-coupon bonds, which
are normally issued at a significant discount from face value and do not
provide for periodic interest payments. Zero-coupon bonds may experi-
ence greater volatility in market value than similar maturity debt obliga-
tions which provide for regular interest payments.

Investment Transactions and Investment Income: Investment transactions
are recorded on the dates the transactions are entered into (the trade
dates). Realized gains and losses on security transactions are deter-
mined on the identified cost basis. Dividend income is recorded on the
ex-dividend dates. Interest income is recognized on the accrual method.
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. Dividends and distributions to Preferred
Shareholders are accrued and determined as described in Note 5.

Income Taxes: It is the Fund’s policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment com-
panies and to distribute substantially all of its taxable income to its
shareholders. Therefore, no federal income tax provision is required.

The Fund files US federal and various state and local tax returns. No
income tax returns are currently under examination. The statute of limita-
tions on the Fund’s US federal tax returns remains open for each of the
four years ended July 31, 2008. The statutes of limitations on the Fund’s
state and local tax returns may remain open for an additional year
depending upon the jurisdiction.

Recent Accounting Pronouncement: In March 2008, Statement of
Financial Accounting Standards No. 161, “Disclosures about Derivative
Instruments and Hedging Activities — an amendment of FASB Statement
No. 133” (“FAS 161”), was issued. FAS 161 is intended to improve finan-
cial reporting for derivative instruments by requiring enhanced disclosure
that enables investors to understand how and why an entity uses deriva-
tives, how derivatives are accounted for, and how derivative instruments
affect an entity’s results of operations and financial position. FAS 161
is effective for financial statements issued for fiscal years and interim
periods beginning after November 15, 2008. The impact on the Fund’s
financial statement disclosures, if any, is currently being assessed.

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 have 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 the other certain BlackRock Closed-End Funds.

The deferred compensation plan is not funded and obligations there-
under represent general unsecured claims against the general assets of
the Fund. The 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.

Other: Expenses directly related to the Fund are charged to that
Fund. Other operating expenses shared by several funds are pro-rated
among those funds on the basis of relative net assets or other appro-
priate methods.

2. Investment Advisory Agreement and Other Transactions
with Affiliates:

The Fund has entered into an Investment Advisory Agreement with
BlackRock Advisors, LLC (the “Advisor”), an indirect, wholly owned
subsidiary of BlackRock, Inc., to provide investment advisory and admin-
istration services. As of January 31, 2009, The PNC Financial Services
Group, Inc. (“PNC”) and Bank of America Corporation (“BAC”) are the
largest stockholders of BlackRock, Inc. (“BlackRock”). BAC became a
stockholder of BlackRock following its acquisition of Merrill Lynch & Co.,
Inc. (“Merrill Lynch”) on January 1, 2009. Prior to that date, both PNC
and Merrill Lynch were considered affiliates of the Fund under the 1940
Act. Subsequent to the acquisition, PNC remains an affiliate, but due to
the restructuring of Merrill Lynch’s ownership interest of BlackRock, BAC
is not deemed to be an affiliate under the 1940 Act.

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 0.55%
of the Fund’s average daily net assets. Average daily net assets is the
average daily value of the Fund’s total assets minus the sum of its
accrued liabilities.

The Advisor has agreed to waive its advisory fees by the amount of
investment advisory fees the Fund pays to the Advisor indirectly through
its investment in affiliated money market funds. This amount is included
in fees waived by advisor on the Statement of Operations.

The Advisor has entered into a separate sub-advisory agreement with
BlackRock Investment Management, LLC (“BIM”), an affiliate of the
Advisor, under which the Advisor pays BIM for services it provides, a
monthly fee that is a percentage of the investment advisory fee paid
by the Fund to the Advisor.

Notes to Financial Statements (continued)

For the six months ended January 31, 2009, the Fund reimbursed the
Advisor $1,969 for certain accounting services, which is included in
accounting services on the Statement of Operations.

Certain officers and/or directors of the Fund are officers and/or directors
of BlackRock, Inc. or its affiliates. The Fund reimburses the Advisor for
compensation paid to the Fund’s Chief Compliance Officer.

3. Investments:

Purchases and sales of investments, excluding short-term securities, for
the six months ended January 31, 2009 were $10,050,439 and
$33,072,979, respectively.

4. Concentration, Market and Credit Risk:

The Fund’s invests a substantial amount of its assets in issuers located
in a single state or limited number of states. Please see the Schedule
of Investments for concentrations in specific states.

Many municipalities insure repayment of their bonds, which reduces
the risk of loss due to issuer default. The market value of these bonds
may fluctuate for other reasons, including market perception of the
value of such insurance, and there is no guarantee that the insurer
will meet its obligations.

In the normal course of business, the Fund invests in securities and
enters into transactions where risks exist due to fluctuations in the
market (market risk) or failure of the issuer of a security to meet all its
obligations (credit risk). The value of securities held by the Fund may
decline in response to certain events, including those directly involving
the issuers whose securities are owned by the Fund; conditions affecting
the general economy; overall market changes; local, regional or global
political, social or economic instability; and currency and interest rate
and price fluctuations. Similar to credit risk, the Fund may be exposed
to counterparty risk, or the risk that an entity with which the Fund has
unsettled or open transactions may default. Financial assets, which
potentially expose the Fund to credit and counterparty risks, consist
principally of investments and cash due from counterparties. The extent
of the Fund’s exposure to credit and counterparty risks with respect to
these financial assets is approximated by their value recorded in the
Fund’s Statement of Assets and Liabilities.

5. Capital Share Transactions:

Common Shares

The Fund is authorized to issue 200,000,000 shares, including
Preferred Shares, par value $0.10 per share, all of which were initially
classified as Common Shares. The Board is authorized however to
reclassify any unissued Common Shares without approval of the holders
of Common Shares.

Shares issued and outstanding for the six months ended January 31,
2009 and the year ended July 31, 2008 remained constant.

Preferred Shares

The Preferred Shares are redeemable at the option of the Fund, in whole
or in part, on any dividend payment date at its liquidation preference
per share plus any accumulated or unpaid dividends whether or not
declared. The Preferred Shares are also subject to mandatory redemp-
tion at $25,000 per share plus any accumulated or unpaid dividends,
whether or not declared, if certain requirements relating to the composi-
tion of the assets and liabilities of the Fund, as set forth in the Fund’s
Articles Supplementary, are not satisfied.

The holders of Preferred Shares have voting rights equal to the holders
of Common Shares (one vote per share) and will vote together with
holders of Common Shares (one vote per share) as a single class.
However, the holders of Preferred Shares, voting as a separate class, are
also entitled to elect two Directors for the Fund. In addition, the 1940
Act requires that along with approval by shareholders that might other-
wise be required, the approval of the holders of a majority of any out-
standing Preferred Shares, voting separately as a class would be
required to (a) adopt any plan of reorganization that would adversely
affect the Preferred Shares, (b) change the Fund’s subclassification as a
closed-end investment company or change its fundamental investment
restrictions or (c) change its business so as to cease to be an invest-
ment company.

The Fund had the following series of Preferred Shares outstanding and
effective yields at January 31, 2009:

	Shares	Yield
Series A	1,220	0.731%
Series B	1,220	0.716%

Dividends on seven-day Preferred Shares are cumulative at a rate,
which is reset every seven days based on the results of an auction. If
the Preferred Shares fail to clear the auction on an auction date, the
Fund is required to pay the maximum applicable rate on the Preferred
Shares to holders of such shares for each successive dividend period
until such time as the shares are successfully auctioned. The maximum
applicable rate on the Preferred Shares is the higher of 110% of the AA
commercial paper rate or 110% of 90% of the Kenny S&P 30-day High
Grade Index rate divided by 1.00 minus the marginal tax rate. The low,
high and average dividend rates on the Preferred Shares of the Fund for
the six months ended January 31, 2009 were as follows:

	Low	High	Average
Series A	0.594%	11.347%	3.610%
Series B	0.594%	11.728%	3.113%

18 BLACKROCK MUNIHOLDINGS FUND II, INC.

JANUARY 31, 2009

Notes to Financial Statements (concluded)

For the six months ended January 31, 2009, the Preferred Shares of the
Fund failed to clear any of its auctions. As a result, the Preferred Shares
dividend rates were reset to the maximum applicable rate, which ranged
from 0.594% to 11.728% . A failed auction is not an event of default for
the Fund but has a negative impact on the liquidity of Preferred Shares.
A failed auction occurs when there are more sellers of a fund’s auction
rate preferred shares than buyers. It is impossible to predict how long
this imbalance will last. A successful auction for the Fund’s Preferred
Shares may not occur for some time, if ever, and even if liquidity does
resume, Preferred Shareholders may not have the ability to sell the
Preferred Shares at their liquidation preference.

The Fund may not declare dividends or make other distributions on
Common Shares or purchase any such shares if, at the time of the
declaration, distribution or purchase, asset coverage with respect to the
outstanding Preferred Shares is less than 200%.

Prior to December 22, 2008, the Fund paid commissions to certain
broker-dealers at the end of each auction at an annual rate of 0.25%,
calculated on the aggregate principal amount. As of December 22,
2008, commissions paid to broker-dealers on preferred shares that
experienced a failed auction were reduced to 0.15% on the aggregate
principal amount. The Fund will continue to pay commissions of 0.25%
on the aggregate principal amount of all shares that successfully
clear their auctions. Merrill Lynch, Pierce, Fenner & Smith Incorporated
(“MLPF&S”), a wholly owned subsidiary of Merrill Lynch, earned commis-
sions of $65,949 for the period August 1, 2008 through December 31,
2008. Subsequent to that date, neither MLPF&S or Merrill Lynch are
considered affiliates of the Fund.

Shares issued and outstanding during the six months ended January 31,
2009 remained constant.

During the year ended July 31, 2008, the Fund announced the following
redemptions of Preferred Shares at a price of $25,000 per share plus
any accrued and unpaid dividends through the redemption date:

	Redemption	Shares	Aggregate
	Date	Redeemed	Principal
Series A	6/25/08	520	$13,000,000
Series B	6/23/08	520	$13,000,000

The Fund financed the Preferred Share redemptions with cash received
from TOB transactions.

6. Capital Loss Carryforward:

As of July 31, 2008, the Fund had capital loss carryforwards
available to offset future realized capital gains through the indicated
year of expiration:

Expires July 31,
2009	$12,107,981
2010	689,205
2011	189,408
Total	$12,986,594

7. Restatement Information:

Subsequent to the initial issuance of their July 31, 2006 financial state-
ments, the Fund determined that the criteria for sale accounting had not
been met for certain transfers of municipal bonds, and that these trans-
fers should have been accounted for as secured borrowings rather than
as sales. As a result, certain financial highlights for the years ended July
31, 2005 and July 31, 2004 have been restated to give effect to record-
ing the transfers of the municipal bonds as secured borrowings, includ-
ing recording interest on the bonds as interest income and interest on
the secured borrowings as interest expense.

8. Subsequent Events:

The Fund paid a net investment income dividend to holders of Common
Shares in the amount of $0.063 per share on March 2, 2009 to share-
holders of record on February 13, 2009.

The dividends declared on Preferred Shares for the period February 1,
2009 to February 28, 2009 were as follows:

Series A	$ 17,244

Additional Information (continued)

Dividend Policy

The Fund’s dividend policy is to distribute all or a portion of their net
investment income to its shareholders on a monthly basis. In order to
provide shareholders with a more stable level of dividend distributions,
the Fund may at times pay out less than the entire amount of net invest-
ment income earned in any particular month and may at times in any
particular month pay out such accumulated but undistributed income
in addition to net investment income earned in that month. As a result,

the dividends paid by the Fund for any particular month may be more
or less than the amount of net investment income earned by the Fund
during such month. The Fund’s current accumulated but undistributed
net investment income, if any, is disclosed in the Statements of Assets
and Liabilities, which comprises part of the financial information included
in this report.

General Information

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 elimi-
nate duplicate mailings of shareholder documents. Mailings of your
shareholder documents may be householded indefinitely unless you
instruct us otherwise. 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.

Quarterly performance, semi-annual and annual reports and other
information regarding the Fund may be found on BlackRock’s website,
which can be accessed at http://www.blackrock.com. This reference
to BlackRock’s website is intended to allow investors public access to
information regarding the Fund and does not, and is not intended to,
incorporate BlackRock’s website into this report.

Availability of Quarterly Schedule of Investments

The Fund files its complete schedule of portfolio holdings with the
SEC for the first and third quarters of each fiscal year on Form
N-Q. The Fund’s Forms N-Q are available on the SEC’s website at
http://www.sec.gov and may also be reviewed and copied at the

SEC’s Public Reference Room in Washington, DC. Information on the
operation of the Public Reference Room may be obtained by calling

Articles Supplementary

Effective September 13, 2008, following approval by the Fund’s Board
and the applicable rating agencies, the Board amended the terms of
the Fund’s Articles Supplementary in order to allow the Fund to enter
into TOB transactions, the proceeds of which were used to redeem a
portion of the Fund’s Preferred Shares. Accordingly, the definition of
Inverse Floaters was amended to incorporate the Fund’s permissible

ratio of floating rate instruments into inverse floating rate instruments.
Additionally, conforming changes and certain formula modifications
concerning inverse floaters were made to the definitions of Moody’s
Discount Factor and S&P Discount Factor, as applicable, to integrate
the Fund’s investments in TOBs into applicable calculations.
