2 ANNUAL REPORT

APRIL 30, 2010

Dear Shareholder

Although overall global economic and financial conditions have generally improved over the past year, the period ended with high levels of market volatility
and diminishing investor confidence sparked by the sovereign debt crisis in Europe, concerns over the strength of the economic recovery and uncertainty
surrounding the future of interest rate policies. Additionally, as the period drew to a close, the increasing likelihood of more stringent financial market regula-
tions added to the overall sense of investment uncertainty. Despite the uneven nature of recent market conditions, we continue to believe that the “Great
Recession” likely ended at some point last summer, thanks primarily to massive fiscal and monetary stimulus, and that the global economy remains in
recovery mode.

Global equity markets bottomed in early 2009 and since that time have moved unevenly higher as investors were lured back into the markets by depressed
valuations, desire for higher yields and improvements in corporate earnings prospects. There have been several corrections along the way and volatility levels
have remained elevated — reflections of mixed economic data, lingering deflation issues (especially in Europe) and uncertainty surrounding financial regula-
tions. On balance, however, improving corporate revenues and profits and a positive macro backdrop helped push stock prices higher over the last twelve
and six months. From a geographic perspective, US equities have outpaced their international counterparts in recent months, as the domestic economic
recovery has been more pronounced and as credit-related issues have held European markets down.

Within fixed income markets, yields have been moving unevenly as improving economic conditions have been acting to push Treasury yields higher (and
prices correspondingly lower), while concerns over ongoing deflation threats have acted as a counterweight. As the period drew to a close, Treasury yields
were falling as investors flocked to the “safe haven” asset class in the face of escalating uncertainty. Over the course of the last twelve and six months, how-
ever, Treasuries underperformed other areas of the bond market, particularly the high yield sector, which has been benefiting from increased investor
demand. Meanwhile, municipal bonds slightly outperformed taxable sectors over both the six- and twelve-month periods thanks to continued high demand
levels, but have continued to face the headwinds of ongoing state and local budget problems. As in the taxable arena, high yield municipals have been out-
performing the rest of the market.

Regarding cash investments, yields on money market securities remain near all-time lows (producing returns only marginally above zero percent), with the
Federal Open Market Committee reiterating that economic circumstances are likely to necessitate an accommodative interest rate stance for an “extended
period.”


Against this backdrop, the major market averages posted the following returns:
Total Returns as of April 30, 2010	6-month	12-month
US equities (S&P 500 Index)	15.66%	38.84%
Small cap US equities (Russell 2000 Index)	28.17	48.95
International equities (MSCI Europe, Australasia, Far East Index)	2.48	34.43
3-month Treasury bill (BofA Merrill Lynch 3-Month Treasury Bill Index)	0.04	0.15
US Treasury securities (BofA Merrill Lynch 10-Year US Treasury Index)	(0.54)	(1.32)
Taxable fixed income (Barclays Capital US Aggregate Bond Index)	2.54	8.30
Tax-exempt fixed income (Barclays Capital Municipal Bond Index)	3.68	8.85
High yield bonds (Barclays Capital US Corporate High Yield 2% Issuer Capped Index)	11.60	42.53

Past performance is no guarantee of future results. Index performance shown for illustrative purposes only. You cannot invest directly in an index.

Global financial markets continue to show signs of improvement, but questions about the strength and sustainability of the recovery abound. Through peri-
ods of uncertainty, as ever, BlackRock’s full resources are dedicated to the management of our clients’ assets. For additional market perspective and invest-
ment insight, visit www.blackrock.com/shareholdermagazine, where you’ll find the most recent issue of our award-winning Shareholder® magazine, as well

Trust Summary as of April 30, 2010

BlackRock Investment Quality Municipal Trust Inc.

Investment Objective

BlackRock Investment Quality Municipal Trust Inc. (BKN) (the “Trust”) seeks to provide high current income which, in the opinion of bond counsel to the
issuer, is exempt from regular federal income tax consistent with the preservation of capital.

No assurance can be given that the Trust’s investment objective will be achieved.

Performance

For the 12 months ended April 30, 2010, the Trust returned 34.50% based on market price and 26.55% based on net asset value (“NAV”). For the same
period, the closed-end Lipper General Municipal Debt Funds (Leveraged) category posted an average return of 28.13% on a market price basis and
22.67% on a NAV basis. All returns reflect reinvestment of dividends. During the period, the Trust moved from a discount to NAV to a premium, which
accounts for the difference between performance based on price and performance based on NAV. The Trust benefited from a tightening of credit spreads,
specifically within the corporate high yield sector, which helped the Trust’s lower-quality holdings outperform. In addition, we actively structured new-issue
deals with discounted coupons at the longer end of the Trust’s duration range. These holdings benefited from the outperformance of the new-issue market,
the flattening of the yield curve and the reduced supply of tax-exempt issuance due to Build America Bonds (BAB) issuance. We also diversified the Trust’s
holdings to increase exposure to specialty-state paper, which outperformed as a result of increased demand by retail buyers. Conversely, the Trust’s shorter
maturity holdings, as well as its bonds with greater negative convexity, underperformed the market.

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.

Trust Summary as of April 30, 2010

BlackRock Long-Term Municipal Advantage Trust

Investment Objective

BlackRock Long-Term Municipal Advantage Trust (BTA) (the “Trust”) seeks to provide current income which, in the opinion of bond counsel to the issuer, is
exempt from regular federal income tax.

No assurance can be given that the Trust’s investment objective will be achieved.

Performance

For the 12 months ended April 30, 2010, the Trust returned 31.25% based on market price and 26.81% based on NAV. For the same period, the closed-
end Lipper General Municipal Debt Funds (Leveraged) category posted an average return of 28.13% on a market price basis and 22.67% on a NAV basis.
All returns reflect reinvestment of dividends. The Trust's discount to NAV, which narrowed during the period, accounts for the difference between performance
based on price and performance based on NAV. Positive performance was attributable in part to sector allocation decisions and included concentrations in
health care, tobacco and corporate-related debt, which all performed well. Increasing risk appetite has also proven beneficial given the portfolio’s focus on
lower-rated credits. Additionally, portfolio positioning with respect to a modestly long duration stance and an emphasis on longer-dated bonds was additive
in an environment where yields on the long end of the curve fell substantially. Negative factors included underweight positioning in the transportation, public
utilities and education sectors, all of which have performed well on a relative basis.

APRIL 30, 2010

Trust Summary as of April 30, 2010

BlackRock Municipal 2020 Term Trust

Investment Objective

BlackRock Municipal 2020 Term Trust (BKK) (the “Trust”) seeks to provide current income exempt from regular federal income tax and to return $15 per
share (the initial public offering price) on or about December 31, 2020.

No assurance can be given that the Trust’s investment objective will be achieved.

Performance

For the 12 months ended April 30, 2010, the Trust returned 23.52% based on market price and 26.97% based on NAV. For the same period, the closed-
end Lipper General Municipal Debt Funds (Leveraged) category posted an average return of 28.13% on a market price basis and 22.67% on a NAV basis.
All returns reflect reinvestment of dividends. The Trust’s premium to NAV, which narrowed during the period, accounts for the difference between performance
based on price and performance based on NAV. The Trust benefited from declining interest rates, which pushed bond prices higher. Although the Trust has a
generally shorter maturity profile relative to its Lipper category, performance was enhanced by the Trust’s allocation to longer maturities in the high yield sec-
tor. This sector outperformed as credit spreads narrowed in an improving market. Additionally, the Trust’s allocations to the health care sector overall and the
hospitals sub-sector in particular outperformed for the period. The Trust is managed to meet a 2020 termination date, and as such, maintains a generally
shorter duration than that of its Lipper category, which comprises longer-duration funds. Accordingly, the Trust did not fully benefit from the price apprecia-
tion that occurred among longer-dated securities.

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.

No assurance can be given that the Trust’s investment objective will be achieved.

Performance

For the 12 months ended April 30, 2010, the Trust returned 30.49% based on market price and 32.75% based on NAV. For the same period, the closed-

emphasis on longer-dated bonds was additive in an environment where yields on the long end of the curve fell substantially. Negative factors included
underweight positioning in the tax-backed and public utilities sectors, both of which have performed well on a relative basis. Above market weight exposure

APRIL 30, 2010

Trust Summary as of April 30, 2010

BlackRock Pennsylvania Strategic Municipal Trust

Investment Objective

BlackRock Pennsylvania Strategic Municipal Trust (BPS) (the “Trust”) seeks to provide monthly income which, in the opinion of bond counsel to the issuer,
is exempt from regular federal and Pennsylvania income taxes.

No assurance can be given that the Trust’s investment objective will be achieved.

Performance

For the 12 months ended April 30, 2010, the Trust returned 49.41% based on market price and 23.80% based on NAV. For the same period, the closed-
end Lipper Pennsylvania Municipal Debt Funds category posted an average return of 29.96% on a market price basis and 18.43% on a NAV basis. All
returns reflect reinvestment of dividends. The Trust moved from a discount to NAV to a premium by period end, which accounts for the difference between
performance based on price and performance based on NAV. The Trust benefited from efforts to increase weighting in interest-rate-sensitive bonds, as tax-
exempt 30-year interest rates rallied 30 basis points (0.30%) lower. A greater weighting in the housing and health care sectors also contributed to Trust
performance, as credit spreads generally tightened in these sectors. Conversely, a low relative distribution yield detracted from performance. Over the period,
the Trust’s income component was a drag on total return performance, but recent efforts to increase current income have resulted in dividend growth and
should be a positive factor in future returns.

The Benefits and Risks of Leveraging

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

To leverage, all the Trusts, except for BTA, issue Preferred Shares, which pay
dividends at prevailing short-term interest rates, and invest 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 each Trust on its longer-term portfolio investments. To
the extent that the total assets of each Trust (including the assets obtained
from leverage) are invested in higher-yielding portfolio investments, each
Trust’s Common Shareholders will benefit from the incremental net income.

To illustrate these concepts, assume a Trust’s Common Shares capitalization
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 Trust pays dividends on the $50 million of Preferred Shares
based on the lower short-term interest rates. At the same time, the securi-
ties purchased by the Trust with assets received from Preferred Shares
issuance earn 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 Trust’s long-term investments, and therefore the
Common Shareholders are the beneficiaries of the incremental net income.

If short-term interest rates rise, narrowing the differential between short-
term and long-term interest rates, the incremental net income pickup on
the Common Shares will be reduced or eliminated completely. Furthermore,
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 Trust pays divi-
dends on the higher short-term interest rates whereas the Trust’s total port-
folio earns income based on lower long-term interest rates.

Furthermore, the value of a Trust’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 redemp-
tion value of the Trust’s Preferred Shares does not fluctuate in relation to
interest rates. As a result, changes in interest rates can influence the Trust’s
NAV positively or negatively in addition to the impact on Trust performance
from leverage from Preferred Shares discussed above.

The Trusts may also leverage their 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 Trusts with economic
benefits in periods of declining short-term interest rates, but expose the
Trusts to risks during periods of rising short-term interest rates similar to

those associated with Preferred Shares issued by the Trusts, as described
above. Additionally, fluctuations in the market value of municipal bonds
deposited into the TOB trust may adversely affect each Trust’s NAVs per
share.

The use of leverage may enhance opportunities for increased income to the
Trusts and Common Shareholders, but as described above, it also creates
risks as short- or long-term interest rates fluctuate. Leverage also will gen-
erally cause greater changes in the Trusts’ 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 Trusts’ 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, each Trust’s net income will be
less than if leverage had not been used, and therefore the amount avail-
able for distribution to Common Shareholders will be reduced. Each Trust
may be required to sell portfolio securities at inopportune times or at dis-
tressed 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 a Trust to incur losses. The use of leverage may limit each
Trust’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 the Trusts. Each Trust
will incur expenses in connection with the use of leverage, all of which are
borne by Common Shareholders and may reduce income to the Common
Shares.

Under the Investment Company Act of 1940, the Trusts are permitted to
issue Preferred Shares in an amount of up to 50% of their total managed
assets at the time of issuance. Under normal circumstances, each Trust
anticipates that the total economic leverage from Preferred Shares and/or
TOBs will not exceed 50% of its total managed assets at the time such
leverage is incurred. As of April 30, 2010, the Trusts had economic leverage
from Preferred Shares and/or TOBs as a percentage of their total managed
assets as follows:


	Percent of
	Leverage
BKN	37%
BTA	36%
BKK	38%
BFK	37%
BPS	40%
BSD	37%

Derivative Financial Instruments

The Trusts may invest in various derivative instruments, including finan-
cial futures contracts, as specified in Note 2 of the Notes to Financial
Statements, which may constitute forms of economic leverage. Such instru-
ments are used to obtain exposure to a market without owning or taking
physical custody of securities or to hedge market and/or interest rate risks.
Such derivative instruments involve risks, including the imperfect correlation
between the value of a derivative instrument and the underlying asset or
illiquidity of the derivative instrument. The Trusts’ ability to successfully use
a derivative instrument depends on the investment advisor’s ability to accu-

rately predict pertinent market movements, which cannot be assured. The
use of derivative instruments may result in losses greater than if they had
not been used, may require the Trusts to sell or purchase portfolio securi-
ties at inopportune times or for distressed values, may limit the amount of
appreciation the Trusts can realize on an investment or may cause the
Trusts to hold a security that they might otherwise sell. The Trusts’ invest-
ments in these instruments are discussed in detail in the Notes to
Financial Statements.

• 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 assets
and liabilities
• Level 2 — other observable inputs (including, but not limited to: quoted prices for
similar assets or liabilities in markets that are active, quoted prices for identical
or 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
circumstances, to the extent observable inputs are not available (including the
Trust’s own assumptions used in determining the fair value of investments)
The inputs or methodologies used for valuing securities are not necessarily an
indication of the risk associated with investing in those securities. For information
about the Trust’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 April 30, 2010 in determining
the fair valuation of the Trust’s investments:

• 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 assets
and liabilities
• Level 2 — other observable inputs (including, but not limited to: quoted prices for
similar assets or liabilities in markets that are active, quoted prices for identical
or 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
circumstances, to the extent observable inputs are not available (including the
Trust’s own assumptions used in determining the fair value of investments)
The inputs or methodologies used for valuing securities are not necessarily an
indication of the risk associated with investing in those securities. For information
about the Trust’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 April 30, 2010 in determining
the fair valuation of the Trust’s investments:

BlackRock Municipal 2020 Term Trust (BKK)

• 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 assets
and liabilities
• Level 2 — other observable inputs (including, but not limited to: quoted prices for
similar assets or liabilities in markets that are active, quoted prices for identical
or 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
circumstances, to the extent observable inputs are not available (including the
Trust’s own assumptions used in determining the fair value of investments)
The inputs or methodologies used for valuing securities are not necessarily an
indication of the risk associated with investing in those securities. For information
about the Trust’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 April 30, 2010 in determining
the fair valuation of the Trust’s investments:

• 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 assets
and liabilities
• Level 2 — other observable inputs (including, but not limited to: quoted prices for
similar assets or liabilities in markets that are active, quoted prices for identical
or 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, repayment 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
circumstances, to the extent observable inputs are not available (including the
Trust’s own assumptions used in determining the fair value of investments)
The inputs or methodologies used for valuing securities are not necessarily an indi-
cation of the risk associated with investing in those securities. For information about
the Trust’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 April 30, 2010 in determining
the fair valuation of the Trust’s investments:

Notes to Financial Statements

1. Organization and Significant Accounting Policies:

BlackRock Investment Quality Municipal Trust Inc. (“BKN”) is organized
as a Maryland corporation. BlackRock Long-Term Municipal Advantage
Trust (“BTA”), BlackRock Municipal 2020 Term Trust (“BKK”), BlackRock
Municipal Income Trust (“BFK”), BlackRock Pennsylvania Strategic
Municipal Trust (“BPS”) and BlackRock Strategic Municipal Trust (“BSD”)
(collectively, together with BKN, the “Trusts” or individually as the “Trust”)
are organized as Delaware statutory trusts. BKN, BKK, BFK and BSD are
registered under the Investment Company Act of 1940, as amended (the
“1940 Act”), as diversified, closed-end management investment compa-
nies. BTA and BPS are registered under the 1940 Act as non-diversified,
closed-end management investment companies. The Trusts’ financial state-
ments are prepared in conformity with accounting principles generally
accepted in the United States of America (“US GAAP”), which may require
the use of management accruals and estimates. Actual results may differ
from these estimates. The Board of Directors and the Board of Trustees of
the Trusts are referred to throughout this report as the “Board of Trustees”
or the “Board.” Each Trust 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 Trusts:

Valuation: The Trusts’ policy is to fair value their financial instruments at
market value, using independent dealers and pricing services selected
under the supervision of the Board. Municipal investments (including
commitments to purchase such investments on a “when-issued” basis)
are valued on the basis of prices provided by dealers or pricing services.
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 comp-
arable investments and information with respect to various relationships
between investments. Financial futures contracts traded on exchanges
are valued at their last sale price. Short-term securities with remaining
maturities of 60 days or less may be 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 or is not available, the investment will be
valued by a method approved by each Trust’s Board as reflecting fair value
("Fair Value Assets"). When determining the price for Fair Value Assets, the
investment advisor and/or the sub-advisor seeks to determine the price
that each Trust 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 subsequently reported to the Board or a committee thereof.

Forward Commitments and When-Issued Delayed Delivery Securities: The
Trusts may purchase securities on a when-issued basis and may purchase
or sell securities on a forward commitment basis. Settlement of such trans-
actions normally occurs within a month or more after the purchase or sale

commitment is made. The Trusts may purchase securities under such con-
ditions 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
Trusts 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 purchasing a security on a delayed
delivery basis, the Trusts assume the rights and risks of ownership of the
security, including the risk of price and yield fluctuations. In the event of
default by the counterparty, the Trusts’ maximum amount of loss is the
unrealized gain of the commitment, which is shown on the Schedules of
Investments, if any.

Municipal Bonds Transferred to Tender Option Bond Trusts: The Trusts
leverage their assets through the use of tender option bond 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 investment advisor
may also contribute municipal bonds to a TOB into which a Trust has con-
tributed 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 a Trust include the right of the Trust (1) to cause the holders of a pro-
portional share of the short-term 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 Trust. The TOB may also
be terminated without the consent of the Trust upon the occurrence of cer-
tain events as defined in the TOB agreements. Such termination events may
include the bankruptcy or default of the municipal bond, a substantial
downgrade in credit quality of the municipal bond, 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 bond 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 Trust, which typically
invests the cash in additional municipal bonds. Each Trust’s transfer of the
municipal bonds to a TOB is accounted for as a secured borrowing, there-
fore the municipal bonds deposited into a TOB are presented in the Trusts’
Schedules of Investments and the proceeds from the issuance of the
short-term floating rate certificates are shown as trust certificates in the
Statements of Assets and Liabilities.

Interest income from the underlying municipal bonds are recorded by the
Trusts on an accrual basis. Interest expense incurred on the secured bor-
rowing and other expenses related to remarketing, administration and
trustee services to a TOB are reported as expenses and fees of the Trusts.
The short-term 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. At April 30, 2010, the aggre-
gate value of the underlying municipal bonds transferred to TOBs, the
related liability for trust certificates and the range of interest rates on the
liability for trust certificates were as follows:

BSD	$ 22,954,227	$12,396,382	0.21% – 0.40%

For the year ended April 30, 2010, the Trusts’ average trust certificates
outstanding and the daily weighted average interest rate, including fees,
were as follows:


		Daily
		Weighted
	Average Trust	Average
	Certificates	Interest
	Outstanding	Rate
BKN	$10,982,150	0.72%
BTA	$82,681,431	1.11%
BKK	$ 3,750,000	0.76%
BFK	$65,136,376	0.73%
BPS	$ 701,864	0.84%
BSD	$11,769,343	0.73%

Should short-term interest rates rise, the Trusts’ investments in TOBs may
adversely affect the Trusts’ net investment income and distributions to
Common Shareholders. Also, fluctuations in the market value of municipal
bonds deposited into the TOB may adversely affect the Trusts’ net asset
value per share.

Zero-Coupon Bonds: The Trusts 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 experience
greater volatility in market value than similar maturity debt obligations
which provide for regular interest payments.

Segregation and Collateralization: In cases in which the 1940 Act and
the interpretive positions of the Securities and Exchange Commission
(“SEC”) require that the Trusts either deliver collateral or segregate assets
in connection with certain investments (e.g., financial futures contracts),
each Trust will, consistent with SEC rules and/or certain interpretive letters
issued by the SEC, segregate collateral or designate on its books and
records cash or other liquid securities having a market value at least
equal to the amount that would otherwise be required to be physically
segregated. Furthermore, based on requirements and agreements with
certain exchanges and third party broker-dealers, each party has require-
ments to deliver/deposit securities as collateral for certain investments.

Investment Transactions and Investment Income: For financial reporting
purposes, investment transactions are recorded on the dates the trans-
actions are entered into (the trade dates). Realized gains and losses
on investment transactions are determined on the identified cost basis.
Dividend income is recorded on the ex-dividend dates. Interest income,
including amortization of premium and accretion of discount on debt
securities, is recognized on the accrual basis.

Dividends and Distributions: Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on
the ex-dividend dates. The amount and timing of dividends and distribu-
tions are determined in accordance with federal income tax regulations,
which may differ from US GAAP. Dividends and distributions to Preferred
Shareholders are accrued and determined as described in Note 7.

Income Taxes: It is each Trust’s policy to comply with the requirements of
the Internal Revenue Code of 1986, as amended, applicable to regulated
investment companies and to distribute substantially all of its taxable
income to its shareholders. Therefore, no federal income tax provision
is required.

Each Trust 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 Trusts’ US federal tax returns remains open for the year ended
April 30, 2010, the period ended April 30, 2009 and the preceding three
taxable years of the respective Trust. The statutes of limitations on each of
the Trusts’ state and local tax returns may remain open for an additional
year depending upon the jurisdiction. There are no uncertain tax positions
that require recognition of a tax liability.

Recent Accounting Standard: In January 2010, the Financial Accounting
Standards Board issued amended guidance to improve disclosure about
fair value measurements which will require additional disclosures about
transfers into and out of Levels 1 and 2 and separate disclosures about
purchases, sales, issuances and settlements in the reconciliation for fair
value measurements using significant unobservable inputs (Level 3).
It also clarifies existing disclosure requirements relating to the levels of
disaggregation for fair value measurement and inputs and valuation tech-
niques used to measure fair value. The amended guidance is effective for
financial statements for fiscal years beginning after December 15, 2009,
and interim periods within those fiscal years, except for disclosures about
purchases, sales, issuances and settlements in the rollforward of activity in
Level 3 fair value measurements, which are effective for fiscal years begin-
ning after December 15, 2010 and for interim periods within those fiscal
years. The impact of this guidance on the Trusts’ financial statements and
disclosures is currently being assessed.

Deferred Compensation and BlackRock Closed-End Share Equivalent
Investment Plan: Under the deferred compensation plan approved by
each Trust’s Board, non-interested Trustees (“Independent Trustees”)
may 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 Trustees.
This has approximately the same economic effect for the Independent
Trustees as if the Independent Trustees 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 each
Trust. Each Trust may, however, elect to invest in common shares of other
certain BlackRock Closed-End Funds selected by the Independent Trustees
in order to match its deferred compensation obligations. Investments to

cover each Trust’s deferred compensation liability, if any, are included in
other assets in the Statements of Assets and Liabilities. Dividends and
distributions from the BlackRock Closed-End Fund investments under the
plan are included in income — affiliated in the Statements of Operations.

Other: Expenses directly related to a Trust are charged to that Trust. Other
operating expenses shared by several funds are pro rated among those
funds on the basis of relative net assets or other appropriate methods.
The Trusts have an arrangement with the custodian whereby fees may be
reduced by credits earned on uninvested cash balances, which if applica-
ble are shown as fees paid indirectly in the Statements of Operations. The
custodian imposes fees on overdrawn cash balances, which can be offset
by accumulated credits earned or may result in additional custody charges.

2. Derivative Financial Instruments:

The Trusts may engage in various portfolio investment strategies both to
increase the returns of the Trusts and to economically hedge, or protect,
their exposure to certain risks such as interest rate risk. Losses may arise
if the value of the contract decreases due to an unfavorable change in
the price of the underlying instrument or if the counterparty’s does not per-
form under the contract. To the extent amounts due to the Trusts from their
counterparties are not fully collateralized contractually or otherwise, the
Trusts bear the risk of loss from counterparty non-performance. See Note 1
“Segregation and Collateralization” for information with respect to collateral
practices. In addition, each Trust manages counterparty risk by entering
into agreements only with counterparties that it believes have the financial
resources to honor their obligations and by monitoring the financial stability
of those counterparties. Counterparty risk related to exchange-traded finan-
cial futures contracts is minimal because of the protection against defaults
provided by the exchanges on which they trade.

Financial Futures Contracts: The Trusts may purchase or sell financial
futures contracts to gain exposure to, or economically hedge against,
changes in interest rates (interest rate risk). Financial futures contracts
are contracts for delayed delivery of securities at a specific future date
and at a specific price or yield. Pursuant to the contract, the Trusts agree
to receive from or pay to the broker an amount of cash equal to the daily
fluctuation in value of the contract. Such receipts or payments are known
as margin variation and are recognized by the Trusts as unrealized gains
or losses. When the contract is closed, the Trusts record a realized gain or
loss equal to the difference between the value of the contract at the time
it was opened and the value at the time it was closed. The use of financial
futures transactions involves the risk of an imperfect correlation in the
movements in the price of financial futures contracts, interest rates and
the underlying assets.

3. Investment Advisory Agreement and Other Transactions

with Affiliates:

The PNC Financial Services Group, Inc. ("PNC"), Bank of America
Corporation ("BAC") and Barclays Bank PLC ("Barclays") are the largest
stockholders of BlackRock, Inc. ("BlackRock"). Due to the ownership
structure, PNC is an affiliate of the Trusts for 1940 Act purposes, but BAC
and Barclays are not.

Each Trust entered into an Investment Advisory Agreement with BlackRock
Advisors, LLC (the “Manager”), the Trusts’ investment advisor, an indirect,
wholly owned subsidiary of BlackRock, to provide investment advisory and
administration services. The Manager is responsible for the management
of each Trust’s portfolio and provides the necessary personnel, facilities,
equipment and certain other services necessary to the operations of each
Trust. For such services, each Trust pays the Manager a monthly fee at the
following annual rates of each Trust’s average weekly net assets as follows:


BKN	0.35%
BTA	1.00%
BKK	0.50%
BFK	0.60%
BPS	0.60%
BSD	0.60%

Average weekly net assets for all of the Trusts, except BTA, is the average
weekly value of each Trust’s total assets minus the sum of its accrued
liabilities. For BTA, average weekly net assets is the average weekly value
of the Trust’s total assets minus the sum of its total liabilities.

The Manager has voluntarily agreed to waive a portion of the investment
advisory fees as a percentage of average net assets as follows:


	Through	Rate
BTA	January 31, 2011	0.40%
	January 31, 2012	0.30%
	January 31, 2013	0.20%
	January 31, 2014	0.10%
BFK	July 31, 2009	0.10%
	July 31, 2010	0.05%

ANNUAL REPORT

APRIL 30, 2010

Notes to Financial Statements (continued)

For the year ended April 30, 2010, the Manager waived the following
amounts, which are included in fees waived by advisor in the Statements
of Operations:


BTA	$567,931
BFK	$549,893

The Manager has voluntarily agreed to waive its advisory fees by the
amount of investment advisory fees the Trusts pay to the Manager indi-
rectly through their investment in affiliated money market funds; however,
the Manager does not waive its advisory fees by the amount of investment
advisory fees through its investment in other affiliated investment compa-
nies, if any. This amount is included in fees waived by advisor in the
Statements of Operations. For the year ended April 30, 2010, the amounts
waived were as follows:


BKN	$ 8,791
BTA	$ 2,614
BKK	$ 3,357
BFK	$15,003
BPS	$ 2,180
BSD	$ 3,555

The Manager has entered into a separate sub-advisory agreement with
BlackRock Financial Management, LLC (“BFM”), an affiliate of the Manager.
The Manager pays BFM for services it provides, a monthly fee that is a per-
centage of the investment advisory fees paid by each Trust to the Manager.

BKN has an Administration Agreement with the Manager. The administration
fee paid to the Manager is computed at an annual rate of 0.15% of the

Trust’s average weekly net assets including proceeds from the issuance of
Preferred Shares and TOBs.

For the year ended April 30, 2010, the Trusts reimbursed the Manager for
certain accounting services, which are included in accounting services in
the Statements of Operations. The reimbursements were as follows:


BTA	$ 4,942
BKK	$ 9,005
BFK	$17,922
BPS	$ 858
BSD	$ 2,835

Certain officers and/or trustees of the Trusts are officers and/or directors of
BlackRock or its affiliates. The Trusts reimburse the Manager for compensa-
tion paid to the Trusts’ Chief Compliance Officer.

4. Investments:

Purchases and sales of investments, including paydowns and excluding
short-term securities, for the year ended April 30, 2010, were as follows:


	Purchases	Sales

BPS	$ 11,770,611	$ 7,942,486
BSD	$ 44,939,101	$ 45,902,121

5. Income Tax Information:

Reclassifications: Accounting principles generally accepted in the United States of America require that certain components of net assets be adjusted to
reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset values per share. The
following permanent differences as of April 30, 2010 attributable to amortization methods on fixed income securities and income recognized from pass-
through entities were reclassified to the following accounts:


	BKN	BTA	BFK	BSD
Undistributed net investment income	$ (35,949)	$ (63,480)	$ 2,172	$ (18,794)
Accumulated net realized loss	$ 35,949	$ 63,480	$ (2,172)	$ 18,794

The tax character of distributions paid during the fiscal year ended April 30, 2010, period ended April 30, 2009, and fiscal years ended October 31, 2008
and December 31, 2008 was as follows:

Notes to Financial Statements (continued)
As of April 30, 2010, the tax components of accumulated net earnings (losses) were as follows:
	BKN	BTA	BKK	BFK	BPS	BSD
Undistributed tax—exempt income	$ 4,443,228	$ 2,590,796	$ 10,022,655	$ 9,556,456	$ 469,813	$ 1,390,198

* The differences between book-basis and tax-basis net unrealized gains/losses were attributable primarily to the tax deferral of losses on wash sales, amortization methods for pre-
miums and discounts on fixed income securities, the deferral of post-October capital losses for tax purposes, the timing and recognition of partnership income, the treatment of
residual interests in tender option bond trusts and the deferral of compensation to trustees.

As of April 30, 2010, the Trusts had capital loss carryforwards available to offset future realized capital gains through the indicated expiration dates:

6. Concentration, Market and Credit Risk:

The Trusts invest a substantial amount of their assets in issuers located
in a single state or limited number of states. Please see the Schedules
of Investments for concentrations in specific states.

Many municipalities insure repayment of their bonds, which may reduce
the potential for loss due to credit risk. 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 obligation.

In the normal course of business, the Trusts invest in securities and enter
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 Trusts may decline in response to
certain events, including those directly involving the issuers whose securi-
ties are owned by the Trusts; conditions affecting the general economy;
overall market changes; local, regional or global political, social or eco-
nomic instability; and currency and interest rate and price fluctuations.
Similar to credit risk, the Trusts may be exposed to counterparty risk, or
the risk that an entity with which the Trusts have unsettled or open trans-
actions may default. The Trusts manage counterparty risk by entering
into transactions only with counterparties that they believe have the
financial resources to honor their obligations and by monitoring the finan-
cial stability of those counterparties. Financial assets, which potentially
expose the Trusts to credit and counterparty risks, consist principally of
investments and cash due from counterparties. The extent of the Trusts’
exposure to credit and counterparty risks with respect to these financial
assets is generally approximated by their value recorded in the Trusts’
Statements of Assets and Liabilities, less any collateral held by the Trusts.

7. Capital Share Transactions:

BKK, BFK, BPS and BSD are authorized to issue an unlimited number of
shares, including Preferred Shares, par value $0.001 per share, all of which
were initially classified as Common Shares. BKN is authorized to issue 200
million shares, including Preferred Shares, all of which were initially classi-
fied as Common Shares, par value $0.01 per share. BTA is authorized to
issue an unlimited number of Common Shares, par value $0.001 per
share. BTA is also allowed to issue Preferred Shares but has not done so.
Each Board is authorized, however, to reclassify any unissued shares with-
out approval of Common Shareholders.

Common Shares

At April 30, 2010, the shares owned by an affiliate of the Manager of the
Trusts were as follows:


	Shares
BTA	9,704
BKK	8,028

For the periods shown, shares issued and outstanding increased by the
following amounts as a result of dividend reinvestment:


	Year	Period
	Ended	Ended	Prior
	April 30,	April 30,	Year
	2010	2009	Ended*

BSD	1,237	—	6,166

* The prior year ended for BKN and BFK is October 31, 2008; and December 31, 2008
for BPS and BSD.

Shares issued and outstanding remained constant for BTA and BKK for
the year ended April 30, 2010, and the period ended April 30, 2009, and
for the year ended October 31, 2008 for BTA and for the year ended

Preferred Shares

The Preferred Shares are redeemable at the option of each Trust, in whole
or in part, on any dividend payment date at their liquidation preference
per share plus any accumulated and unpaid dividends whether or not
declared. The Preferred Shares are also subject to mandatory redemption
at their liquidation preference plus any accumulated and unpaid dividends,
whether or not declared, if certain requirements relating to the composition
of the assets and liabilities of a Trust, as set forth in each Trust’s Articles
Supplementary (the “Governing Instrument”) are not satisfied.

From time to time in the future, each Trust may effect repurchases of its
Preferred Shares at prices below their liquidation preference as agreed
upon by the Trust and seller. Each Trust also may redeem its Preferred
Shares from time to time as provided in the applicable Governing
Instrument. Each Trust intends to effect such redemptions and/or repur-
chases to the extent necessary to maintain applicable asset coverage
requirements or for such other reasons as the Board may determine.

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 each Trust. In addition, the 1940 Act requires that
along with approval by shareholders that might otherwise be required, the
approval of the holders of a majority of any outstanding 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
a Trust’s sub-classification as a closed-end investment company or change
its fundamental investment restrictions or (c) change its business so as to
cease to be an investment company.

The Trusts had the following series of Preferred Shares outstanding, effec-
tive yields and reset frequency as of April 30, 2010:


				Reset
		Preferred	Effective	Frequency
	Series	Shares	Yield	Days
BKN	T7	2,804	0.47%	7
	T28	2,234	0.46%	28
BKK	M7	2,318	0.49%	7
	W7	2,318	0.47%	7
	F7	2,318	0.49%	7
BFK	M7	2,167	0.49%	7
	T7	2,167	0.47%	7
	W7	2,167	0.47%	7
	R7	2,167	0.47%	7
	F7	2,167	0.49%	7
BPS	W7	653	0.47%	7
BSD	W7	1,719	0.47%	7

Dividends on seven-day and 28-day Preferred Shares are cumulative at
a rate, which is reset every seven or 28 days, respectively, based on the
results of an auction. If the Preferred Shares fail to clear the auction on
an auction date, each Trust is required to pay the maximum applicable rate
on the Preferred Shares to holders of such shares for successive dividend
periods until such time as the shares are successfully auctioned. The

maximum applicable rate on all series of 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 for each
Trust for the year ended April 30, 2010 were as follows:


	Series	Low	High	Average
BKN	T7	0.26%	0.79%	0.45%
	T28	0.31%	0.75%	0.46%
BKK	M7	0.24%	0.79%	0.44%
	W7	0.26%	0.79%	0.45%
	F7	0.24%	0.76%	0.44%
BFK	M7	0.24%	0.79%	0.45%
	T7	0.26%	0.79%	0.45%
	W7	0.26%	0.79%	0.45%
	R7	0.24%	0.76%	0.44%
	F7	0.24%	0.76%	0.44%
BPS	W7	0.26%	0.79%	0.45%
BSD	W7	0.26%	0.79%	0.45%

Since February 13, 2008, the Preferred Shares of the Trusts failed to
clear any of their auctions. As a result, the Preferred Shares dividend rates
were reset to the maximum applicable rate, which ranged from 0.24% to
0.79% for the year ended April 30, 2010. A failed auction is not an event
of default for the Trusts but it has a negative impact on the liquidity of
Preferred Shares. A failed auction occurs when there are more sellers of a
Trust’s auction rate preferred shares than buyers. A successful auction for
the Trusts’ Preferred Shares may not occur for some time, if ever, and even
if liquidity does resume, holders of the Preferred Shares may not have the
ability to sell the Preferred Shares at their liquidation preference.

The Trusts may not declare dividends or make other distributions on
Common Shares or purchase any such shares if, at the time of the decla-
ration, distribution or purchase, asset coverage with respect to the out-
standing Preferred Shares is less than 200%.

The Trusts pay commissions of 0.25% on the aggregate principal amount
of all shares that successfully clear their auctions and 0.15% on the
aggregate principal amount of all shares that fail to clear their auctions.
Certain broker dealers have individually agreed to reduce commissions for
failed auctions.

During the year ended April 30, 2010, the Trusts 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
	Series	Date	Redeemed	Principal
BKN	T7	7/08/09	22	$ 550,000

We have audited the accompanying statements of assets and liabilities of
BlackRock Investment Quality Municipal Trust Inc., BlackRock Long-Term

ing the schedules of investments, as of April 30, 2010, the related state-

for the year then ended for BlackRock Long-Term Municipal Advantage
Trust, the statements of changes in net assets for the year ended April 30,
2010, for the period November 1, 2008 to April 30, 2009 and for the year
ended October 31, 2008, and the financial highlights for the periods pre-
sented. We have also audited the accompanying statements of assets and
liabilities of BlackRock Municipal 2020 Term Trust, BlackRock Pennsylvania
Strategic Municipal Trust, and BlackRock Strategic Municipal Trust, includ-
ing the schedules of investments, as of April 30, 2010, and the related
statements of operations for the year then ended, the statements of
changes in net assets for year ended April 30, 2010, for the period January
1, 2009 to April 30, 2009 and for the year ended December 31, 2008,
and the financial highlights for the periods presented. These financial state-
ments and financial highlights are the responsibility of the Trusts’ manage-
ment. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements and financial highlights are free of
material misstatement. The Trusts are not required to have, nor were we
engaged to perform, an audit of their internal control over financial report-
ing. 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 Trusts’ internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining,
on a test basis, evidence supporting the amounts and disclosures in the
financial statements, assessing the accounting principles used and signifi-
cant estimates made by management, as well as evaluating the overall
financial statement presentation. Our procedures included confirmation
of securities owned as of April 30, 2010, by correspondence with the
custodian and brokers; where replies were not received from brokers, 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 Investment Quality Municipal Trust Inc., BlackRock Long-Term
Municipal Advantage Trust, and BlackRock Municipal Income Trust as of
April 30, 2010, the results of their operations for the year then ended, the
cash flows for the year then ended for BlackRock Long-Term Municipal
Advantage Trust, the changes in their net assets for the year ended April
30, 2010, for the period November 1, 2008 to April 30, 2009 and for the
year ended October 31, 2008, and the financial highlights for the periods
presented, in conformity with accounting principles generally accepted in
the United States of America. Additionally, in our opinion, the financial
statements and financial highlights referred to above present fairly, in all
material respects, the financial position of BlackRock Municipal 2020 Term
Trust, BlackRock Pennsylvania Strategic Municipal Trust, and BlackRock
Strategic Municipal Trust as of April 30, 2010, the results of their opera-
tions for the year then ended, the changes in their net assets for the year
ended April 30, 2010, for the period January 1, 2009 to April 30, 2009
and for the year ended December 31, 2008, and the financial highlights
for the periods presented, in conformity with accounting principles gener-
ally accepted in the United States of America.

Important Tax Information (Unaudited)

All of the net investment income distributions paid by BKN, BTA, BKK,
BFK, BPS and BSD during the taxable year ended April 30, 2010 qualify
as tax-exempt interest dividends for federal income tax purposes.

APRIL 30, 2010

Automatic Dividend Reinvestment Plans

Pursuant to each Trust’s Dividend Reinvestment Plan (the “Plan”), common
shareholders are automatically enrolled to have all distributions of divi-
dends and capital gains reinvested by Computershare Trust Company, N.A.
(the “Plan Agent”) in the respective Trust’s shares pursuant to the Plan.
Shareholders who do not participate in the Plan will receive all distributions
in cash paid by check and mailed directly to the shareholders of record (or
if the shares are held in street or other nominee name, then to the nomi-
nee) by the Plan Agent, which serves as agent for the shareholders in
administering the Plan.

After BKN, BTA, BFK, BPS, and BSD declares a dividend or determines to
make a capital gain distribution, the Plan Agent will acquire shares for the
participants’ accounts, depending upon the following circumstances, either
(i) through receipt of unissued but authorized shares from the Trust (“newly
issued shares”) or (ii) by purchase of outstanding shares on the open mar-
ket, on the Trust’s primary exchange or elsewhere (“open-market pur-
chases”). If, on the dividend payment date, the net asset value per share
(“NAV”) is equal to or less than the market price per share plus estimated
brokerage commissions (such condition often referred to as a “market pre-
mium”), the Plan Agent will invest the dividend amount in newly issued
shares on behalf of the participants. The number of newly issued shares to
be credited to each participant’s account will be determined by dividing
the dollar amount of the dividend by the NAV on the date the shares are
issued. However, if the NAV is less than 95% of the market price on the
payment date, the dollar amount of the dividend will be divided by 95% of
the market price on the payment date. If, on the dividend payment date,
the NAV is greater than the market value per share plus estimated broker-
age commissions (such condition often referred to as a “market discount”),
the Plan Agent will invest the dividend amount in shares acquired on behalf
of the participants in open-market purchases. If the Plan Agent is unable to
invest the full dividend amount in open market purchases, or if the market
discount shifts to a market premium during the purchase period, the Plan
Agent will invest any un-invested portion in newly issued shares.

After BKK declares a dividend or determines to make a capital gain distri-
bution, the Plan Agent will acquire shares for the participants’ account by
the purchase of outstanding shares on the open market, on BKK’s primary
exchange or elsewhere (“open market purchases”). BKK will not issue any
new shares under the Plan.

Participation in the Plan is completely voluntary and may be terminated or
resumed at any time without penalty by notice if received and processed
by the Plan Administrator prior to the dividend record date; otherwise such
termination or resumption will be effective with respect to any subsequently
declared dividend or other distribution.

The Plan Agent’s fees for the handling of the reinvestment of dividends and
distributions will be paid by each Trust. However, each participant will pay a
pro rata share of brokerage commissions incurred with respect to the Plan
Agent’s open market purchases in connection with the reinvestment of divi-
dends and distributions. The automatic reinvestment of dividends and dis-
tributions will not relieve participants of any federal income tax that maybe
payable on such dividends or distributions.

Each Trust reserves the right to amend or terminate the Plan. There is no
direct service charge to participants in the Plan; however, each Trust
reserves the right to amend the Plan to include a service charge payable
by the participants. Participants that request a sale of shares through the
Plan Agent are subject to a $2.50 sales fee and a $0.15 per share sold
brokerage commission. All correspondence concerning the Plan should be
directed to the Plan Agent at P.O. Box 43078, Providence, RI 02940-3078
or by calling (800) 699-1BFM. All overnight correspondence should be
directed to the Plan Agent at 250 Royall Street, Canton, MA 02021.

56 ANNUAL REPORT

APRIL 30, 2010

Additional Information

Trust Certification

Those Trusts listed for trading on the New York Stock Exchange (“NYSE”)
have filed with the NYSE their annual chief executive officer certification
regarding compliance with the NYSE’s listing standards. Each Trust filed

with the Securities and Exchange Commission (“SEC”) the certification of
its chief executive officer and chief financial officer required by section 302
of the Sarbanes-Oxley Act.

Dividend Policy

The Trusts’ dividend policy is to distribute all or a portion of their net invest-
ment income to its shareholders on a monthly basis. In order to
provide shareholders with a more stable level of dividend distributions, the
Trusts may at times pay out less than the entire amount of net investment
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 Trusts for any particular month may be more or less than the
amount of net investment income earned by the Trusts during such month.
The Trusts’ current accumulated but undistributed net investment income,
if any, is disclosed in the Statements of Assets and Liabilities, which com-
prises part of the financial information included in this report.

General Information

The Trusts do not make available copies of their Statements of Additional
Information because the Trusts’ shares are not continuously offered, which
means that the Statement of Additional Information of each Trust has not
been updated after completion of the respective Trust’s offerings and the
information contained in each Trust’s Statement of Additional Information
may have become outdated.

During the period, there were no material changes in the Trusts’ investment
objectives or policies or to the Trusts’ charters or by-laws that were not
approved by the shareholders or in the principal risk factors associated
with investment in the Trusts. There have been no changes in the persons
who are primarily responsible for the day-to-day management of the
Trusts’ portfolio.

Quarterly performance, semi-annual and annual reports and other informa-
tion regarding the Funds 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 regard-
ing the Funds and does not, and is not intended to, incorporate
BlackRock’s website into this report.

Electronic Delivery

Electronic copies of most financial reports are available on the Trusts’ web-
sites or shareholders can sign up for e-mail notifications of quarterly state-
ments, annual and semi-annual reports by enrolling in the Trusts’ electronic
delivery program.

Shareholders Who Hold Accounts with Investment Advisors, Banks
or Brokerages:

Please contact your financial advisor to enroll. Please note that not all
investment advisors, banks or brokerages may offer this service.

Householding

The Trusts 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 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
call (800) 441-7762.

Availability of Quarterly Portfolio Schedule of Investments

Each Trust 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 Trusts’
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 (800) SEC-0330. Each Trust’s Forms N-Q
may also be obtained upon request and without charge by calling
(800) 441-7762.

Aailability of Proxy Voting Policies and Procedures

A description of the policies and procedures that the Trusts use to
determine how to vote proxies relating to portfolio securities is available
(1) without charge, upon request, by calling (800) 441-7762; (2) at
www.blackrock.com; and (3) on the SEC’s website at http://www.sec.gov.

mation is provided to help you understand what personal information

about you from different sources, including the following: (i) information we
receive from you or, if applicable, your financial intermediary, on applica-
tions, forms or other documents; (ii) information about your transactions

58 ANNUAL REPORT

APRIL 30, 2010

This report is transmitted to shareholders only. It is not a prospectus. Past performance results shown in this report should not be considered a representation
of future performance. Certain Trusts have leveraged their Common Shares, which creates risks for Common Shareholders, including the likelihood of greater
volatility of net asset value and market price of the Common Shares and the risk that fluctuations in the short-term dividend rates of the Preferred Shares,
currently set at the maximum reset rate as a result of failed auctions, may reduce the Common Shares’ yield. Statements and other information herein are
as dated and are subject to change.

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
charge at www.blackrock.com.

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 (retired effective December 31, 2009)
Frank J. Fabozzi
James T. Flynn
W. Carl Kester
Karen P. Robards

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.

financial statements not included in Audit Fees.
2 The nature of the services include tax compliance, tax advice and tax planning.
3 The nature of the services include a review of compliance procedures and attestation thereto.

(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.

(f) Not Applicable

(g) Affiliates’ Aggregate Non-Audit Fees:


	Current Fiscal Year	Previous Fiscal Year
Entity Name	End	End
The BlackRock Strategic	$20,377	$418,128

(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.

Regulation S-X Rule 2-01(c)(7)(ii) – $10,777, 0%

Item 5 – Audit Committee of Listed Registrants – The following individuals are members of the
registrant’s separately-designated standing audit committee established in accordance with
Section 3(a)(58)(A) of the Securities Exchange Act of 1934 (15 U.S.C. 78c(a)(58)(A)):

Item 6 – Investments
(a) The registrant’s Schedule of Investments is included as part of the Report to
Stockholders filed under Item 1 of this form.
(b) Not Applicable due to no such divestments during the semi-annual period covered since
the previous Form N-CSR filing.

Item 7 – Disclosure of Proxy Voting Policies and Procedures for Closed-End Management
Investment Companies – The board of directors has delegated the voting of proxies for the
Fund securities to the Fund’s investment adviser (“Investment Adviser”) pursuant to the
Investment Adviser’s proxy voting guidelines. Under these guidelines, the Investment
Adviser will vote proxies related to Fund securities in the best interests of the Fund and its
stockholders. From time to time, a vote may present a conflict between the interests of the
Fund’s stockholders, on the one hand, and those of the Investment Adviser, or any affiliated
person of the Fund or the Investment Adviser, on the other. In such event, provided that the
Investment Adviser’s Equity Investment Policy Oversight Committee, or a sub-committee
thereof (the “Oversight Committee”) is aware of the real or potential conflict or material
non-routine matter and if the Oversight Committee does not reasonably believe it is able to
follow its general voting guidelines (or if the particular proxy matter is not addressed in the
guidelines) and vote impartially, the Oversight Committee may retain an independent
fiduciary to advise the Oversight Committee on how to vote or to cast votes on behalf of the
Investment Adviser’s clients. If the Investment Adviser determines not to retain an
independent fiduciary, or does not desire to follow the advice of such independent fiduciary,
the Oversight Committee shall determine how to vote the proxy after consulting with the
Investment Adviser’s Portfolio Management Group and/or the Investment Adviser’s Legal
and Compliance Department and concluding that the vote cast is in its client’s best interest
notwithstanding the conflict. A copy of the Fund’s Proxy Voting Policy and Procedures are
attached as Exhibit 99.PROXYPOL. Information on how the Fund voted proxies relating to
portfolio securities during the most recent 12-month period ended June 30 is available

without charge, (i) at www.blackrock.com and (ii) on the SEC’s website at
http://www.sec.gov.

Item 8 – Portfolio Managers of Closed-End Management Investment Companies – as of April 30,
2010.

(a)(1) The registrant is managed by a team of investment professionals comprised of
Theodore R. Jaeckel, Jr., CFA, Managing Director at BlackRock and Walter

municipal tax-exempt management group. Each is jointly responsible for the day-to-
day management of the registrant’s portfolio, which includes setting the registrant’s
overall investment strategy, overseeing the management of the registrant and/or
selection of its investments. Messrs. Jaeckel and O’Connor have been members of
the registrant’s portfolio management team since 2006 and 2006, respectively.

(iv) Potential Material Conflicts of Interest

BlackRock 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 significant shareholders 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 significant
shareholders, 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’ or significant shareholders’) officers, directors or employees are directors or
officers, or companies as to which BlackRock or any of its affiliates or significant
shareholders 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 a fund. In this connection, it should be noted that a portfolio manager
may currently manage certain accounts that are subject to performance fees. In addition, a
portfolio manager 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 April 30, 2010:

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.

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 for the
Fund include a combination of market-based indices (e.g. Barclays Capital Municipal Bond
Index), 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 BlackRock’s ability to sustain and improve its performance
over future periods.

Long-Term Retention and Incentive Plan (“LTIP”) — From time to time long-
term incentive equity awards are granted to certain key employees to aid in retention, align
their interests with long-term shareholder interests and motivate performance. Equity
awards are generally granted in the form of BlackRock, Inc. restricted stock units that, once
vested, settle in BlackRock, Inc. common stock. Messrs. Jaeckel and O’Connor have each
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 the various
investment options. Messrs. Jaeckel and O’Connor have each participated in the deferred
compensation program.

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:

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 3-5% of eligible
compensation. The RSP offers a range of investment options, including registered
investment companies managed by the firm. BlackRock 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.
