2 ANNUAL REPORT

APRIL 30, 2009


Dear Shareholder

The past 12 months reveal a tale of two markets — one of investor pessimism and decided weakness, and another of optimism and some early signs of

recovery. The majority of the past year was characterized by the former as the global financial crisis erupted into the worst recession in decades. Economic

data were uniformly poor and daily headlines recounted the downfalls of storied financial firms, volatile swings in global financial markets, and monumental

government actions that included widespread (and globally coordinated) monetary and quantitative easing by central banks and large-scale fiscal stimuli.

Sentiment improved noticeably in March 2009, however, on the back of new program announcements by the Treasury and Federal Reserve Board, as well

as signs of improved economic performance, such as in retail sales, consumer confidence and select areas of the housing market.

Against this backdrop, US equities contended with unprecedented levels of volatility, posting steep declines early, and then pared some of those losses in

March and April. The experience in international markets was similar to that in the United States, though there was a marked divergence in regional perform-

ance. Notably, emerging economies, which lagged most developed regions through the downturn, were among the market leaders during the late-period rally.

In fixed income markets, while risk aversion remained a dominant theme overall, relatively attractive yields and distressed valuations, alongside a more

favorable macro environment, eventually captured investor attention, leading to a modest recovery in non-Treasury assets. A notable example from the

opposite end of the credit spectrum was the high yield sector, which generally outperformed in the first four months of 2009 after extraordinary challenges

and severe underperformance last year. At the same time, the new year ushered in a return to normalcy for the tax-exempt market, which had registered one

of its worst years on record in 2008.

All told, the major benchmark indexes posted mixed results for the current reporting period, reflective of a bifurcated market.   
Total Returns as of April 30, 2009  6-month  12-month

On June 16, 2009, BlackRock, Inc. announced that it received written notice from Barclays PLC (“Barclays”) in which Barclays’ Board of Directors had

accepted BlackRock’s offer to acquire Barclays Global Investors (“BGI”). Barclays also notified BlackRock that its Board will recommend the transaction to

Barclays’ shareholders for approval at a special meeting to be held in early August 2009. The combination of BlackRock and BGI will bring together market

leaders in active and index strategies to create the preeminent asset management firm. The transaction is expected to close in the fourth quarter 2009

following approval by Barclays’ shareholders, the receipt of client consents and regulatory approvals, and satisfaction of customary closing conditions.

Through periods of market turbulence, as ever, BlackRock’s full resources are dedicated to the management of our clients’ assets. We thank you for entrusting

BlackRock with your investments and look forward to continuing to serve you in the months and years ahead.

Sincerely,

Trust Summary as of April 30, 2009 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.

The Trust’s year end was changed to April 30.

Performance

For the six months ended April 30, 2009, the Trust returned 15.12% based on market price and 13.63% 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 16.50% on a market price basis and 9.58%
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. The Trust’s slightly longer duration position and lower-rated holdings had a positive
impact on performance, as did overweights in the housing and healthcare sectors. Many of these holdings underperformed the market as credit spreads
widened and liquidity became scarcer, but then outperformed significantly as the credit markets began to function more normally. The Trust also benefited
from the opportunities presented by the new-issue market, as anxious issuers, prohibited from issuing debt due to recent market forces, have provided many
attractive values in their rush to tap the loosening credit markets. By contrast, an underweight in tax-backed credits and essential service revenue bonds
detracted from performance. Both of these sectors outperformed early in the period, so the Trust’s light exposure hurt the total return. The Trust maintains
a neutral to slightly long duration bias. The Trust maintained moderate levels of cash during the period, which did not significantly impact performance.

Trust Summary as of April 30, 2009 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.

The Trust’s year end was changed to April 30.

Performance

For the six months ended April 30, 2009, the Trust returned 9.06% based on market price and 15.78% 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 16.50% on a market price basis and 9.58% on a NAV
basis. All returns reflect reinvestment of dividends. The Trust’s discount to NAV, which widened during the period, accounts for the difference between perform-
ance based on price and performance based on NAV. Portfolio positioning, with respect to duration and yield curve, was generally long relative to the Trust’s
peer group. In general, the Trust’s credit profile consistently reflected a high level of exposure to the lower end of the ratings spectrum. While this strategy
generates an above-average dividend yield, it also subjects the Trust to additional volatility during periods when credit spreads are fluctuating. Consequently,
performance tended to suffer late in 2008 when spreads widened, but more recently, the strong rebound in lower-rated bonds allowed the Trust to generate
a strong competitive return, while maintaining the historically attractive dividend.

Trust Summary as of April 30, 2009 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.

The Trust’s year end was changed to April 30.

Performance

For the four months ended April 30, 2009, the Trust returned 22.54% based on market price and 16.39% 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 26.43% on a market price basis and
15.39% on a NAV basis. All returns reflect reinvestment of dividends. The Trust’s premium to NAV, which widened during the period, accounts for the differ-
ence between performance based on price and performance based on NAV. Overall, the Trust performed well as the municipal market recovered from its
2008 lows. Out-of-favor sectors, such as hospital, housing and corporate-backed debt, outperformed the general market and the Trust benefited from its
exposure to these areas. As general market rates declined during the period, liquidity also improved, which resulted in some narrowing of quality spreads.
Leverage magnified the Trust’s positive performance, including income from leverage, as rates reset lower on preferred shares. By contrast, exposure to air-
lines and housing detracted from results, as these issues underperformed in the recessionary environment.

Trust Summary as of April 30, 2009 BlackRock Pennsylvania Strategic Municipal Trust

Investment Objective

BlackRock Pennsylvania Strategic Municipal Trust (BPS) (the “Trust”) seeks to provide monthly income that is exempt from regular federal and
Pennsylvania income taxes. No assurance can be given that the Trust’s investment objective will be achieved.

The Trust’s year end was changed to April 30.

Performance

For the four months ended April 30, 2009, the Trust returned 19.18% based on market price and 12.28% based on net asset value (NAV). For the same
period, the closed-end Lipper Pennsylvania Municipal Debt Funds category posted an average return of 26.92% on a market price basis and 15.57% 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. During the period, progress was made toward improving credit quality and reducing high levels
of cash by purchasing several new issue securities with ratings ranging from AA to AAA. On the whole, Trust performance was negatively affected by further
price deterioration in multi-family housing holdings and a low distribution yield. At period end, the Trust’s cash position remains elevated and will be
deployed opportunistically. The portfolio’s interest rate sensitivity is such that it will outperform in a stable- to lower-interest-rate environment.

Trust Summary as of April 30, 2009 BlackRock Strategic Municipal Trust

Investment Objective

BlackRock Strategic Municipal Trust (BSD) (the “Trust”) seeks to provide high current income 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.

The Trust’s year end was changed to April 30.

Performance

For the four months ended April 30, 2009, the Trust returned 27.11% based on market price and 13.44% 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 26.43% on a market price basis and 15.39%
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. Portfolio positioning with respect to duration and yield curve has generally been long
relative to the peer group. In general, the Trust’s credit profile has consistently reflected a high level of exposure to the lower end of the ratings spectrum. While
this strategy generates an above-average dividend yield, it also subjects the portfolio to additional volatility during periods when credit spreads are fluctuating.
As a consequence, performance tended to suffer early this year when spreads widened, but more recently, the strong rebound in lower-rated bonds has
allowed the Trust to generate a strong competitive return, while maintaining the historically attractive dividend.

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

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 Trusts, except BlackRock Long-Term Municipal Advantage
Trust, 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 yield.

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 Trust’s
total portfolio of $150 million earns the income based on long-term inter-
est rates. In this case, the dividends paid to Preferred Shareholders are
significantly lower than the income earned on the Trust’s long-term invest-
ments, and therefore the Common Shareholders are the beneficiaries of
the incremental yield.

Conversely, if prevailing short-term interest rates rise above long-term inter-
est rates of 6%, the yield curve has a negative slope. In this case, the Trust
pays dividends on the higher short-term interest rates whereas the Trust’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 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 redemption
value of the Trust’s Preferred Shares do 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 from time to time, 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 returns 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 a Trust’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 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, the Trusts’ 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. The Trusts
may be required to sell portfolio securities at inopportune times or below
fair market values in order to comply with regulatory requirements applica-
ble to the use of leverage or as required by the terms of leverage instru-
ments, which may cause the Trusts to incur losses. The use of leverage may
limit the Trusts’ 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.
The Trusts 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 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, 2009, the Trusts had economic leverage
from Preferred Shares and/or TOBs as a percentage of their total managed
assets as follows:

  Percent of 
  Leverage 
BlackRock Investment Quality Municipal Trust Inc  41% 
BlackRock Long-Term Municipal Advantage Trust  38% 
BlackRock Municipal 2020 Term Trust  42% 
BlackRock Municipal Income Trust  42% 
BlackRock Pennsylvania Strategic Municipal Trust  41% 
BlackRock Strategic Municipal Trust  41% 

Derivative Instruments

The Trusts may invest in various derivative instruments, including swap
agreements and futures, and other instruments specified in the Notes to
Financial Statements, which constitute forms of economic leverage. Such
instruments 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 under-
lying asset, possible default of the other party to the transaction and illiq-
uidity of the derivative instrument. The Trusts’ ability to successfully use

a derivative instrument depends on the Advisor’s ability to accurately pre-
dict 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 securities at
inopportune times or for prices other than current market values, may limit
the amount of appreciation the Trusts can realize on an investment or may
cause the Trusts to hold a security that it might otherwise sell. The Trusts’
investments in these instruments are discussed in detail in the Notes to
Financial Statements.

Effective November 1, 2008, the Trust adopted Financial Accounting Standards
Board Statement of Financial Accounting Standards No. 157, “Fair Value Measure-
ments” (“FAS 157”). FAS 157 clarifies the definition of fair value, establishes 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 active, quoted prices for identical
or similar assets 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
Trust’s own assumptions used in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indica-
tion 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, 2009 in determining
the fair valuation of the Trust’s investments:

Valuation  Investments in 
Inputs  Securities 
  Assets 
Level 1  $ 11,400,000 
Level 2  324,819,302 
Level 3

Effective November 1, 2008, the Trust 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 active, quoted prices for identical
or similar assets 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
Trust’s own assumptions used in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indica-
tion 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 the Note 1 of the Notes to Financial Statements.

The following table summarizes the inputs used as of April 30, 2009 in determining
the fair valuation of the Trust’s investments:

Valuation  Investments in 
Inputs  Securities 
  Assets 
Level 1  $ 1,400,185 
Level 2  203,679,751

Financial Accounting Standards Board Statement of Financial Accounting Standards
No. 157, “Fair Value Measurements”, which clarifies the definition of fair value,
establishes a framework for measuring fair values and requires additional disclo-
sures about the use of fair value measurements. Various inputs are used in deter-
mining 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 active, quoted prices for identical
or similar assets 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
Trust’s own assumptions used in determining the fair value of investments)
The inputs or methodology used for valuing securities are not necessarily an indica-
tion 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, 2009 in determining
the fair valuation of the Trust’s investments:

Valuation  Investments in 
Inputs  Securities 
  Assets 
Level 1  $ 2,301,041 
Level 2  410,905,467

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 active, quoted prices for identical
or similar assets 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
Trust’s own assumptions used in determining the fair value of investments)
The inputs or methodology used for valuing securities are not necessarily an indica-
tion 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, 2009 in determining

Financial Accounting Standards Board Statement of Financial Accounting Standards
No. 157, “Fair Value Measurements”, which clarifies the definition of fair value,
establishes a framework for measuring fair values and requires additional disclo-
sures about the use of fair value measurements. Various inputs are used in deter-
mining 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 active, quoted prices for identical
or similar assets 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
Trust’s own assumptions used in determining the fair value of investments)
The inputs or methodology used for valuing securities are not necessarily an indica-
tion 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 the Note 1 of the Notes to Financial Statements.
The following table summarizes the inputs used as of April 30, 2009 in determining
the fair valuation of the Trust’s investments:

Valuation  Investments in 
Inputs  Securities 
  Assets 
Level 1  $ 301,197 
Level 2  135,218,003 
Level 3

Notes to Financial Statements

1. Organization and Significant Accounting Policies:

BlackRock Investment Quality Municipal Trust Inc. (“Investment Quality
Municipal”) is organized as a Maryland corporation. BlackRock Long-Term
Municipal Advantage Trust (“Long-Term Municipal”), BlackRock Municipal
2020 Term Trust (“Municipal 2020”), BlackRock Municipal Income Trust
(“Municipal Income”), BlackRock Pennsylvania Strategic Municipal Trust
(“Pennsylvania Strategic”) and BlackRock Strategic Municipal Trust (“Strategic
Municipal”) (the “Trusts” or individually as the “Trust) are organized as
Delaware statutory trusts. Investment Quality Municipal, Municipal 2020,
Municipal Income and Strategic Municipal are registered under the Invest-
ment Company Act of 1940, as amended (the “1940 Act”), as diversified
closed-end management investment companies. Long-Term Municipal and
Pennsylvania Strategic are registered as non-diversified, closed-end man-
agement investment companies under the 1940 Act. Investment Quality
Municipal, Long Term Municipal and Municipal Income are herein referred
to as the Municipal Trusts. Municipal 2020 is herein referred to as the
2020 Trust. Pennsylvania Strategic and Strategic Municipal are herein
referred to as the Strategic Trusts. The Municipal Trusts, the 2020 Trust
and the Strategic Trusts are referred herein collectively as the “Trusts” or
individually as a “Trust”. The Trusts’ financial statements are prepared in
conformity with accounting principles generally accepted in the United
States of America, which may require the use of management accruals
and estimates. Actual results may differ from these estimates. The Trusts’
year ends were changed to April 30 as follows:

  Current Period  Prior Year End 
Investment Quality     
Municipal  November 1, 2008 to April 30, 2009  October 31, 2008 
Long-Term Municipal  November 1, 2008 to April 30, 2009  October 31, 2008 
Municipal 2020  January 1, 2009 to April 30, 2009  December 31, 2008 
Municipal Income  November 1, 2008 to April 30, 2009  October 31, 2008 
Pennsylvania Strategic  January 1, 2009 to April 30, 2009  December 31, 2008 
Strategic Municipal  January 1, 2009 to April 30, 2009  December 31, 2008 

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 of Investments: 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 selected under the
supervision of each Trust’s Board of Directors/Trustees (the “Board”). In
determining the value of a particular investment, pricing services may use
certain information with respect to transactions in such investments, quota-
tions from dealers, pricing matrixes, market transactions in comparable
investments and information with respect to various relationships between
investments. Financial futures contracts traded on exchanges are valued
at their last sale price. Swap agreements are valued by utilizing quotes
received daily by the Trusts’ pricing service or through brokers, which are
derived using daily swap curves and trades of underlying securities.
Short-term securities with maturities less than 60 days 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, 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 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.

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

Financial futures contracts — Each Trust may purchase or sell financial
futures contracts and options on such futures contracts for investment
purposes or to manage its interest rate risk. Futures are contracts for
delayed delivery of securities at a specific future date and at a specific
price or yield. Pursuant to the contract, the Trust agrees to receive from,
or pay to, the broker an amount of cash equal to the daily fluctuation in
value of the contract. Such receipts or payments are known as margin
variation and are recognized by the Trust as unrealized gains or losses.
When the contract is closed, the Trust records a realized gain or loss
equal to the difference between the value of the contract at the time it
was opened and the value at the time it was closed. The use of futures
transactions involves the risk of an imperfect correlation in the move-
ments in the price of futures contracts, interest rates and the underlying
assets, and the possible inability of counterparties to meet the terms of
their contracts.

Forward interest rate swaps — Each Trust may enter into forward interest
rate swaps for investment purposes. The Trusts may enter into swap
agreements in which the Trust and the counterparty agree to make
periodic net payments on a specified notional amount. In a forward
interest rate swap, a Trust and the counterparty agree to make periodic
net payments on a specified notional contract amount, commencing
on a specified future effective date, unless terminated earlier. These
periodic payments received or made by the Trusts are recorded in the
accompanying Statements of Operations as realized gains or losses,
respectively. Swaps are marked-to-market daily and changes in value
are recorded as unrealized appreciation (depreciation). When the swap
is terminated, the Trusts will record a realized gain or loss equal to the
difference between the proceeds from (or cost of) the closing trans-
action and the Trusts’ basis in the contract, if any. The Trusts generally
intend to close each forward interest rate swap before the effective date
specified in the agreement and therefore avoid entering into the interest
rate swap underlying each forward interest rate swap. Swap transac-
tions involve, to varying degrees, elements of credit and market risk in
excess of the amounts recognized on the Statements of Assets and

Liabilities. Such risks involve the possibility that there will be no liquid
market for these agreements, that the counterparty to the agreements
may default on its obligation to perform or disagree as to the meaning
of the contractual terms in the agreements, and that there may be unfa-
vorable changes in interest rates and/or market values associated with
these transactions.

Forward Commitments and When-Issued Delayed Delivery Securities: Each
Trust 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 condi-
tions 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 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.

Municipal Bonds Transferred to Tender Option Bond Trusts: Each Trust
leverages its 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 securities. 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 Trusts include the right of the Trusts (1) to cause the holders of a pro-
portional 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 Trusts. The TOB may also be termi-
nated without the consent of the Trusts upon the occurrence of certain
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. The Trusts’ 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 shown on the Statements of Assets and
Liabilities as trust certificates.

Interest income from the underlying securities is recorded by the Trusts 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 Trusts. 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. At April 30, 2009, the aggregate value of the underlying municipal
bonds transferred to TOBs, the related liability for trust certificates and the
range of interest rates for trust certificates were as follows:

  Underlying    Range of 
  Municipal    Interest 
  Bonds  Liability  Rates for 
  Transferred  for Trust  Trust 
  to TOBs  Certificates  Certificates 
Investment Quality Municipal  $ 18,734,804  $10,137,799  0.653% – 1.188% 
Long-Term Municipal  $109,826,876  $79,135,000  0.617% – 3.768% 
Municipal 2020  $ 5,368,750  $ 3,750,000  0.928% 
Municipal Income  $ 84,000,466  $46,388,860  0.553% – 1.686% 
Strategic Municipal  $ 14,405,502  $7,763,958  0.370% – 0.928% 

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

Zero-Coupon Bonds: Each Trust 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 each Trust segregates assets in connection with certain invest-
ments (e.g. when-issued delayed delivery securities, futures and swaps),
each Trust will, consistent with certain interpretive letters issued by the SEC,
designate on their 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, the
Trusts may also be required to deliver or deposit securities as collateral for
certain investments (e.g. when-issued delayed delivery securities, futures
and swaps).

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 determined
on the identified cost basis. Dividend income is recorded on the ex-divi-
dend dates. Interest income is recognized on the accrual method. Each
Trust 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.

APRIL 30, 2009


Notes to Financial Statements (continued)

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

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 or
period ended April 30, 2009 and the preceding three taxable years of the
respective Trust. The statutes of limitations on the Trusts’ 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 2020 Trust and the Strategic
Trusts adopted FAS 161, which was effective January 1, 2009, and the
adoption had no impact on their financial statement disclosures. For the
Municipal Trusts, the impact on the 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
each Trust’s Board, non-interested Directors/Trustees (“Independent
Trustees”) 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 approxi-
mately the same economic effect for the Independent Trustees as if the
Independent Trustees had invested the deferred amounts directly in the
other certain BlackRock Closed-End Funds.

The deferred compensation plan is not funded and obligations hereunder
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 are included in other
assets on the Statements of Assets and Liabilities. Dividends and distribu-
tions from the BlackRock Closed-End Fund investments under the plan are
included in income — affiliated on the Statements of Operations.

Other: Expenses directly related to each 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.
Custodian fees may be reduced by amounts calculated on uninvested
cash balances which are shown on the Statements of Operations as fees
paid indirectly.

2. Investment Advisory Agreement and Other Transactions
with Affiliates:

Each Trust entered into an Investment Advisory Agreement with BlackRock
Advisors, LLC (the “Advisor”), an indirect, wholly owned subsidiary of
BlackRock, Inc. (“BlackRock”), to provide investment advisory and adminis-
tration services. The PNC Financial Services Group, Inc. (“PNC”) and Bank
of America Corporation (“BAC”) are the largest stockholders of 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 Trusts 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 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 Advisor a monthly fee of the Trust’s average weekly net
assets at the following rates:

  Rate 
Investment Quality Municipal  0.35% 
Long-Term Municipal  1.00% 
Municipal 2020  0.50% 
Municipal Income  0.60% 
Pennsylvania Strategic  0.60% 
Strategic Municipal  0.60% 

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

The Advisor has voluntarily agreed to waive a portion of the investment
advisory fee as a percentage of net assets as follows:

  Through  Rate 
Long-Term Municipal  January 31, 2008 — January 31, 2011  0.40% 
  January 31, 2012  0.30% 
  January 31, 2013  0.20% 
  January 31, 2014  0.10% 
Municipal Income  July 31, 2008  0.15% 
  July 31, 2009  0.10% 
  July 31, 2010  0.05% 
Strategic Trusts  December 31, 2008  0.05% 

These amounts are included in fees waived by Advisor on the Statements
of Operations. For the two periods shown, the waivers were as follows:

  Current  Prior 
  Period  Year 
Long-Term Municipal  $228,689  $ 654,515 
Municipal Income  $384,390  $1,316,719 
Pennsylvania Strategic    $ 21,848 
Strategic Municipal    $ 76,520 

The Advisor has agreed to waive its advisory fees by the amount of invest-
ment advisory fees each Trust pays to the Advisor indirectly through its

investment in affiliated money market funds. These amounts are included
in fees waived by advisor on the Statements of Operations. For the two
periods shown, the amounts were as follows:

  Current  Prior 
  Period  Year 
Investment Quality Municipal  $ 10,003  $ 29,489 
Long-Term Municipal  $ 2,451  $ 5,235 
Municipal 2020  $ 5,309  $ 4,744 
Municipal Income  $ 16,344  $ 51,023 
Pennsylvania Strategic  $ 1,356  $ 18,973 
Strategic Municipal  $ 2,190  $ 6,589 

The Advisor has entered into a separate sub-advisory agreement with
BlackRock Financial Management, Inc. (“BFM”), an affiliate of the Advisor,
with respect to the Trusts, under which the Advisor pays BFM for services it
provides, a monthly fee that is a percentage of the investment advisory fee
paid by each Trust to the Advisor.

Investment Quality Municipal has an Administration Agreement with the
Advisor. The administration fee paid to the Advisor 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.

Each Trust reimbursed the Advisor for certain accounting services, which are
included in accounting services on the Statements of Operations. For the
two periods shown, the amounts were as follows:

  Current  Prior 
  Period  Year 
Long-Term Municipal  $ 1,410  $ 5,494 
Municipal 2020  $ 2,959  $ 7,445 
Municipal Income  $ 7,133  $ 12,913 
Pennsylvania Strategic  $ 279  $ 742 
Strategic Municipal  $ 912  $ 2,509 

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

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the
current period were as follows:

  Purchases  Sales 
Investment Quality Municipal  $ 88,470,557  $ 81,071,719 
Long-Term Municipal  $ 29,738,161  $ 38,626,456 
Municipal 2020  $ 19,685,064  $ 5,050,484 
Municipal Income  $ 86,152,568  $ 83,867,674 
Pennsylvania Strategic  $ 5,824,567  $ 2,842,095 
Strategic Municipal  $ 13,554,589  $ 8,313,157 

4. Concentration, Market and Credit Risk:

Each Trust invests a substantial amount of its 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 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 insur-
ance, 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 securities
are owned by the Trusts; 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 Trusts may be exposed to counterparty risk, or the risk
that an entity with which the Trusts have unsettled or open transactions
may default. 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 counter-
party risks with respect to these financial assets is approximated by their
value recorded in the Trusts’ Statements of Assets and Liabilities.

5. Capital Share Transactions:

Long-Term Municipal, Municipal 2020, Municipal Income and the Strategic
Trusts 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. Investment Quality Municipal is authorized
to issue 200 million, including Preferred Shares, all of which were initially
classified as Common Shares par value $0.01 per share. Each Trust’s
Board is authorized, however, to reclassify any unissued shares without
approval of Common Shareholders.

Common Shares

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

  Current  Prior  Two Years 
  Period  Year  Prior 
Investment Quality Municipal    138,790  83,554 
Long-Term Municipal      36,210 
Municipal Income  31,369  152,320  197,269 
Pennsylvania Strategic    1,436  2,582 
Strategic Municipal    6,166  14,017 

Shares issued and outstanding remained constant for Long-Term Municipal
for the current period and prior year. Shares issued and outstanding
remained constant for Municipal 2020 for the current period, prior year
and two years prior.

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 plus
any accumulated unpaid dividends whether or not declared. The Preferred
Shares are also subject to mandatory redemption at their liquidation pref-
erence plus any accumulated or unpaid dividends, whether or not declared,

Notes to Financial Statements (continued)

if certain requirements relating to the composition of the assets and liabili-
ties of a Trust, as set forth in each Trust’s Statement of Preferences/Articles
Supplementary (“Governing Instrument”), as applicable, are not satisfied.

From time to time in the future, the Trusts that have issued Preferred
Shares may effect repurchases of such shares at prices below their liquida-
tion preferences as agreed upon by the Trusts and seller. The Trusts also
may redeem such shares from time to time as provided in the applicable
Governing Instrument. The Trusts intend to effect such redemptions and/or
repurchases 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, holders of
Preferred Shares, voting as a separate class, are also entitled to elect two
Trustees 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 sepa-
rately 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 funda-
mental 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 at April 30, 2009:

        Reset 
    Preferred  Effective  Frequency 
  Series  Shares  Yield  Days 
Investment Quality Municipal  T7  2,826  0.792%  7 
  T28  2,252  0.746%  28 
Municipal 2020  M7  2,318  0.792%  7 
  W7  2,318  0.792%  7 
  F7  2,318  0.792%  7 
Municipal Income  M7  2,345  0.792%  7 
  T7  2,345  0.792%  7 
  W7  2,345  0.792%  7 
  R7  2,345  0.792%  7 
  F7  2,345  0.792%  7 
Pennsylvania Strategic  W7  673  0.792%  7 
Strategic Municipal  W7  1,910  0.792%  7 

Dividends on seven-day and 28-day Preferred Shares are cumulative at a
rate which is reset every seven or 28 days based on the results of an auc-
tion. 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 com-
mercial 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 period
ended April 30, 2009 were as follows:

  Series  Low  High  Average 
Investment Quality Municipal  T7  0.594%  3.088%  1.171% 
  T28  0.594%  3.088%  1.340% 
Municipal 2020  M7  0.594%  1.721%  0.798% 
  W7  0.640%  1.279%  0.782% 
  F7  0.594%  1.721%  0.792% 
Municipal Income  M7  0.594%  3.474%  1.109% 
  T7  0.594%  3.087%  1.118% 
  W7  0.640%  2.988%  1.114% 
  R7  0.594%  2.999%  1.087% 
  F7  0.594%  3.305%  1.104% 
Pennsylvania Strategic  W7  0.640%  1.279%  0.761% 
Strategic Municipal  W7  0.640%  1.279%  0.761% 

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 0.594%
to 2.285% for the period ended April 30, 2009. 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. It is impossible to pre-
dict how long this imbalance will last. 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
declaration, distribution or purchase, asset coverage with respect to the
outstanding Preferred Shares is less than 200%.

Prior to December 22, 2008, the Trusts 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 Trusts will pay commissions of 0.25% on the aggregate principal
amount of all shares that successfully clear their auctions. For the two
periods shown, Merrill Lynch, Pierce, Fenner & Smith Incorporated, a wholly
owned subsidiary of Merrill Lynch, earned commissions as follows for the
current period through December 31, 2008 (after which Merrill Lynch was
no longer considered an affiliate).

Preferred Shares issued and outstanding for the current period and two
years prior remained constant for each Trust.

6. 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. The following permanent differences as of April 30, 2009 attributable to the difference
between amortization methods on fixed income securities and non-deductible expenses were reclassified to the following accounts:

  Investment Quality  Long-Term  Municipal  Municipal  Pennsylvania  Strategic 
  Municipal    Municipal  2020  Income  Strategic  Municipal 
Paid-in capital  $ (475)             
Undistributed net investment income  $ (4,322)  $ 15,490    $ (9,127)  $ 6  $ (4,383) 
Accumulated net realized loss  $ 4,797  $ (15,490)    $ 9,127  $ (6)  $ 4,383 
The tax character of distributions paid during the periods shown were as follows:

Notes to Financial Statements (concluded)

As of April 30, 2009, the tax components of accumulated losses were as follows:

  Investment Quality             Long-Term  Municipal  Municipal  Pennsylvania  Strategic 
  Municipal  Municipal  2020  Income  Strategic  Municipal 
Undistributed tax-exempt income  $ 2,745,445  $ 1,728,339  $ 3,680,378  $ 6,074,234  $ 152,564  $ 673,416

Net unrealized losses*  (31,440,593)  (35,802,513)  (46,092,380)  (114,382,030)  (3,425,415)  (18,475,833)

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

As of April 30, 2009, the Trusts had capital loss carryforwards available to offset future realized capital gains through the indicated expiration dates:

To the Shareholders and Board of Directors/Trustees of:
BlackRock Investment Quality Municipal Trust Inc.
BlackRock Long-Term Municipal Advantage Trust
BlackRock Municipal 2020 Term Trust
BlackRock Municipal Income Trust
BlackRock Pennsylvania Strategic Municipal Trust
BlackRock Strategic Municipal Trust (collectively

We have audited the accompanying statements of assets and liabilities,
including the schedules of investments, of BlackRock Investment Quality
Municipal Trust Inc., BlackRock Long-Term Municipal Advantage Trust, and
BlackRock Municipal Income Trust as of April 30, 2009, and the related
statements of operations for the period November 1, 2008 to April 30,

flows for the period November 1, 2008 to April 30, 2009 and for the year
ended October 31, 2008 for BlackRock Long-Term Municipal Advantage
Trust, the statements of changes in net assets for the period November 1,
2008 to April 30, 2009 and for each of the two years in the period ended
October 31, 2008, and the financial highlights for the period November 1,
2008 to April 30, 2009 and for each of the five years in the period ended
October 31, 2008. We have also audited the accompanying statements of
assets and liabilities, including the schedules of investments, of BlackRock
Municipal 2020 Term Trust, BlackRock Pennsylvania Strategic Municipal
Trust, and BlackRock Strategic Municipal Trust, as of April 30, 2009, and
the related statements of operations for the period January 1, 2009 to
April 30, 2009, and for the year ended December 31, 2008, the state-
ments of changes in net assets for the period January 1, 2009 to April 30,
2009 and for each of the two years in the period ended December 31,
2008, and the financial highlights for the period January 1, 2009 to April
30, 2009 and for each of the five years in the period ended December 31,
2008. These financial statements and financial highlights are the responsi-
bility of the Trusts’ management. Our responsibility is to express an opinion
on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements and financial highlights are free of
material misstatement. The 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 include confirmation
of the securities owned as of April 30, 2009, 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, 2009, the results of their operations for the period November 1,
2008 to April 30, 2009 and for the year ended October 31, 2008, the
statement of cash flows for the period November 1, 2008 to April 30,
2009 and for the year ended October 31, 2008 for BlackRock Long-Term
Municipal Advantage Trust, the changes in their net assets for the period
November 1, 2008 to April 30, 2009 and for each of the two years in the
period ended October 31, 2008, and the financial highlights for the period
November 1, 2008 to April 30, 2009 and for the five years in the period
ended April 30, 2009, 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

Automatic Dividend Reinvestment Plans

Pursuant to each Trust’s Dividend Reinvestment Plan (the “Plan”), common
shareholders are automatically enrolled to have all distributions of dividends
and capital gains reinvested by Computershare Trust Company, N.A. (the
“Plan Agent”) in the respective Trust’s shares pursuant to the Plan. Share-
holders 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 nominee)
by the Plan Agent, which serves as agent for the shareholders in adminis-
tering the Plan.

After a Trust declares a dividend or determines to make a capital gain
distribution, the Plan Agent will acquire shares for the participants’ accounts,
depending upon the circumstances described below, 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 market,
on the Trust’s primary exchange or elsewhere (“open-market purchases”).
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 broker-
age commissions (such condition being referred to herein as “market
premium”), 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

brokerage commissions (such condition being referred to herein as “market
discount”), the Plan Agent will invest the dividend amount in shares acquired
on behalf of the participants in open-market purchases.

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 ter-
mination 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 may
be 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 par-
ticipants. 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.

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 Statements of Additional Information of the Trusts have not
been updated after completion of the Trusts’ offering and the information
contained in the Trusts’ Statements 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’ portfolios.

tion regarding the Trusts may be found on BlackRock’s website, which can

wise. If you do not want the mailing of these documents to be combined

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. The 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 affect the yield to Common Shareholders. 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
Frank J. Fabozzi
James T. Flynn
W. Carl Kester
Karen P. Robards
Robert S. Salomon, Jr. (retired effective December 31, 2008)

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

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

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

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

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

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

(f) Not Applicable

(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.

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.

                       (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, 2009:

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”) — The LTIP is a long-term
incentive plan that seeks to reward certain key employees. Beginning in 2006, awards are
granted under the LTIP in the form of BlackRock, Inc. restricted stock units that, if properly
vested and subject to the attainment of certain performance goals, will be settled in
BlackRock, Inc. common stock. 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, O’Connor and Browse 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. Messrs. Jaeckel, O’Connor and Browse are eligible to
participate in these plans.
