2	ANNUAL REPORT	OCTOBER 31, 2008

A Letter to Shareholders

Dear Shareholder

It has been a tumultuous period for investors, marked by almost daily headlines of deepening turmoil in financial markets and a darkening economic outlook. The news took an extraordinarily heavy tone late in the period as the credit crisis boiled over and triggered unprecedented failures and consolidation in the financial sector, stoking fears of a market and economic collapse and prompting a series of new government programs designed to contain and combat the fallout.

The Federal Reserve Board (the “Fed”) has taken decisive measures to restore liquidity and stabilize the financial system. Key moves included slashing the target federal funds rate 250 basis points (2.50%) between November 2007 and April 2008 and providing massive cash injections and lending programs. In October, as credit conditions further deteriorated, the central bank cut the key interest rate by 50 basis points on two separate occasions—on October 8 in coordination with five other global central banks, and again during its regularly scheduled meeting on October 29. This left the key short-term rate at just 1.0%, its lowest level since 2004. While the U.S. economy appeared fairly resilient through the second quarter of 2008, the third quarter saw a contraction of 0.5%, and a more significant decline is expected for the fourth quarter. Moreover, on December 1, the National Bureau of Economic Research confirmed that the U.S. had entered a recession in December 2007.

Against this backdrop, U.S. equity markets experienced intense volatility, with periods of downward pressure punctuated by sharp rebounds. Losses were significant and broad-based, though small-cap stocks fared moderately better than their larger counterparts. Non-U.S. markets decelerated at a considerably faster pace than domestic equities—a stark reversal of recent years’ trends, when international stocks generally outpaced U.S. stocks.

Treasury issues also traded in a volatile fashion, but rallied overall (yields fell and prices correspondingly rose) and outperformed other fixed income assets as investors continued their flight to higher quality and more liquid securities. Tax-exempt issues generally underperformed, as problems among municipal bond insurers and the collapse in the market for auction rate securities afflicted the group throughout the course of the past year. At the same time, the above mentioned economic headwinds and malfunctioning credit markets plagued the high yield sector, with the third quarter of 2008 marking one of the worst periods in history for the asset class.

Facing unprecedented volatility and macro pressures, the major benchmark indexes generally recorded losses for the six- and 12-month reporting periods:

Trust Summary as of October 31, 2008	BlackRock Investment Quality Municipal Trust


Investment Objective

	BlackRock Investment Quality Municipal Trust (BKN) (the “Trust”) seeks is 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.

Performance

	For the 12 months ended October 31, 2008, the Trust returned (33.11)% based on market price and (22.93)% 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 (19.05)% on a NAV basis. All returns reflect reinvestment of dividends. The Trust moved from a premium to NAV to a discount by period-end, which accounts for the difference between performance based on price and performance based on NAV. Trust performance was positively impacted by its above-average distribution rate and its more neutral duration positioning at the beginning of the period. Trust performance was negatively affected by longer-dated holdings, which proved volatile as risk spreads increased and the municipal yield curve steepened. The Trust’s overweight exposure to lower-quality and national names also detracted from performance as liquidity concerns rattled the markets.

	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 October 31, 2008	BlackRock Municipal Income Trust


Investment Objective

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

Performance

	For the 12 months ended October 31, 2008, the Trust returned (41.05)% based on market price and (25.69)% based on NAV. For the same period, the closed-end Lipper General Municipal Debt Funds (Leveraged) category posted an average return of (19.05)% on a NAV basis. All returns reflect reinvestment of dividends. The Trust moved from a premium to NAV to a discount by period-end, which accounts for the difference between performance based on price and performance based on NAV. The Trust was successful in delivering a competitive yield, but relative performance suffered as credit spreads widened and prices on the Trust’s lower-rated holdings declined. Management prefers to maintain the Trust’s competitive yield, and does not anticipate any significant near-term changes in portfolio composition.

Trust Summary as of October 31, 2008	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.

Performance

	For the 12 months ended October 31, 2008, the Trust returned (26.49)% based on market price and (33.64)% based on NAV. For the same period, the closed-end Lipper General Municipal Debt Funds (Leveraged) category posted an average return of (19.05)% 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 was successful in delivering a competitive yield, but relative performance suffered as credit spreads widened and prices on the Trust’s lower-rated holdings declined. Financial market dislocations, and the associated deteriorations in liquidity and funding conditions, have precipitated a widespread reduction in leverage. The Trust has taken steps to modestly reduce leverage to more sustainable levels.

	The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

The Benefits and Risks of Leveraging

The Funds 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, BlackRock Investment Quality Municipal Trust and BlackRock Municipal Income Trust issue Preferred Shares, which pay dividends at prevailing short-term interest rates, and invests the proceeds in long-term municipal bonds. In general, the concept of leveraging is based on the premise that the cost of assets to be obtained from leverage will be based on short-term interest rates, which normally will be lower than the income earned by each Fund on its longer-term portfolio investments. To the extent that the total assets of each Fund (including the assets obtained from leverage) are invested in higher-yielding portfolio investments, each Fund’s Common Shareholders will benefit from the incremental yield.

To illustrate these concepts, assume a Fund’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 Fund pays dividends on the $50 million of Preferred Shares based on the lower short-term interest rates. At the same time, the Fund’s total portfolio of $150 million earns the income based on long-term interest rates. Conversely, if prevailing short-term interest rates rise above long-term interest rates of 6%, the yield curve has a negative slope. In this case, the Fund pays dividends on the higher short-term interest rates whereas the Fund’s total portfolio earns income based on lower long-term interest rates.

In this case, the dividends paid to Preferred Shareholders are significantly lower than the income earned on the Fund’s long-term investments, and therefore the Common Shareholders are the beneficiaries of the incremental yield. However, if short-term interest rates rise, narrowing the differential between short-term and long-term interest rates, the incremental yield pickup on the Common Shares will be reduced or eliminated completely.

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

The Funds 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 Funds with economic benefits in periods of declining short-term interest rates, but expose the Funds to risks during periods of rising short-term interest rates similar to those associated with Preferred Shares issued by the Funds, as described above. Additionally, fluctuations in the market value of municipal securities deposited into the TOB trust may adversely affect the Funds’ NAVs per share.

The use of leverage may enhance opportunities for increased returns to the Funds and Common Shareholders, but as described above, it also creates risks as short- or long-term interest rates fluctuate. Leverage also will generally cause greater changes in a Fund’s NAV, market price and dividend rate than a comparable portfolio without leverage. If the income derived from securities purchased with assets received from leverage exceeds the cost of leverage, the Funds’ 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 Funds’ net income will be less than if leverage had not been used, and therefore the amount available for distribution to Common Shareholders will be reduced. The Funds may be required to sell portfolio securities at inopportune times or below fair market values in order to comply with regulatory requirements applicable to the use of leverage or as required by the terms of leverage instruments, which may cause the Funds to incur losses. The use of leverage may limit the Funds’ 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 Funds. The Funds 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, BlackRock Investment Quality Municipal Trust and BlackRock Municipal Income Trust 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 Fund anticipates that the total economic leverage from Preferred Shares and TOBs will not exceed 50% of its total managed assets at the time such leverage is incurred. As of October 31, 2008, the Funds had economic leverage from Preferred Shares and TOBs as a percentage of their total managed assets as follows:



	Percent of Leverage

Investment Quality Municipal	43%
Municipal Income	43%
Long-Term Municipal	44%

Derivative Instruments

The Funds may invest in various derivative instruments, including swap agreements and futures, and other instruments specified in the Notes to Financials Statements, which constitute additional 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 underlying asset, possible default of the other party to the transaction and illiquidity of the derivative instrument. The Funds’ ability to successfully use a derivative instrument depends on the Advisor’s ability to accurately 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 Funds to sell or purchase portfolio securities at inopportune times or for prices other than current market values, may limit the amount of appreciation the Funds can realize on an investment or may cause the Funds to hold a security that it might otherwise sell. The Funds’ investments in these instruments are discussed in detail in the Notes to Financial Statements.

	ANNUAL REPORT	OCTOBER 31, 2008	25

Notes to Financial Statements

1. Organization and Significant Accounting Policies:

BlackRock Investment Quality Municipal Trust Inc. (“Investment Quality Municipal”) was organized as a Maryland corporation. BlackRock Municipal Income Trust (“Municipal Income”) and BlackRock Long-Term Municipal Advantage Trust (“Long-Term Municipal”) were organized as Delaware statutory trusts. Investment Quality Municipal, Municipal Income and Long-Term Municipal are individually referred to as a “Trust” and collectively as the “Trusts”. Investment Quality Municipal and Municipal Income are registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as diversified, closed-end management investment companies. Long-Term Municipal is registered under the 1940 Act as a non-diversified, closed-end management investment company. 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. 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 Trustees or Board of Directors, as appropriate (collectively, the “Board” the members of which are referred to as “Directors”). In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from bond 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 utilizing quotes received daily by the Trusts’ pricing service or through brokers. Short-term securities are valued at amortized cost. Investments in open-end investment companies are valued at net asset value each business day.

In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the market value of such investment, the investment will be valued by a method approved by the Board as reflecting fair value (“Fair Value Assets”). When determining the price for Fair Value Assets, the 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: The Trusts may engage in various portfolio investment strategies both to increase the return of the Trusts and to hedge, or protect, their 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 financial futures contracts for investment purposes or to manage its interest rate risk. 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 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 movements 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. 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. Forward interest rate swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). When the forward interest rate swap is terminated, a Trust will record a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and each Trust’s basis in the contract, if any. Forward interest rate swap transactions 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 unfavorable changes in interest rates and/or market values associated with these transactions.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.

	Municipal Bonds Transferred to Tender Option Bond Trusts: The Trusts may 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 securities. Other funds managed by the investment advisor may also contribute municipal securities to a TOB into which a Trust has contributed 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 proportional share of the




26	ANNUAL REPORT	OCTOBER 31, 2008

Notes to Financial Statements (continued)

floating rate certificates to tender their certificates at par, and (2) to transfer, within seven days, a corresponding share of the municipal securities from the TOB to the Trusts. The cash received by the TOB from the sale of the short-term floating rate certificates, less transaction expenses, is paid to the Trusts, which typically invest the cash in additional municipal securities. The Trusts’ transfer of the municipal securities to a TOB is accounted for as a secured borrowing, therefore the municipal securities deposited into a TOB are presented in each Trust’s Schedule of Investments and the proceeds from the transaction are reported as a liability for 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 October 31, 2008, the aggregate value of the underlying municipal securities transferred to TOBs, the related liability for trust certificates and the range of interest rates were as follows:



	Underlying Municipal Securities Transferred to TOBs		Liability for Trust Certificates		Range of Interest Rates

Investment Quality	$	18,121,593	$	10,807,799		2.559% – 4.195%
Municipal Income	$	76,537,903	$	46,388,859		2.423% – 4.212%
Long-Term Municipal	$	103,967,770	$	89,795,000		3.000% – 4.750%

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’ investments in TOBs likely will adversely affect the Trusts’ investment income and distributions to Common Shareholders. Fluctuations in the market value of municipal securities deposited into the TOB may adversely affect each Trust’s 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 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 segregate assets in connection with certain investments (e.g., financial futures contracts and swaps) or certain borrowings, each Trust will, consistent with certain interpretive letters issued by the SEC, 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, the Trusts may also be required to deliver or deposit securities as collateral for certain investments (e.g., financial futures contracts 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-dividend dates. Interest income is recognized on the accrual method. Each Trust amortizes all premiums and discounts on debt securities. Consent fees are compensation for agreeing to changes in the terms of debt instruments and are included in interest income on the Statements of Operations. For the year ended October 31, 2008, Investment Quality Municipal and Municipal Income had $350,000 and $1,725,000, respectively, in consent fees.

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 4.

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 provisions are required.

Effective April 30, 2008, the Trusts implemented Financial Accounting Standards Board (“FASB”) Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109” (“FIN 48”). FIN 48 prescribes the minimum recognition threshold a tax position must meet in connection with accounting for uncertainties in income tax positions taken or expected to be taken by an entity, including investment companies, before being measured and recognized in the financial statements. The investment advisor has evaluated the application of FIN 48 to the Trusts, and has determined that the adoption of FIN 48 does not have a material impact on the Trusts’ financial statements. Each Trust files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Trusts’ U.S. federal tax returns remain open for the years ended October 31, 2005 through October 31, 2007. 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 Pronouncements: In September 2006, Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“FAS 157”), was issued and is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. The impact on the Trusts’ financial statements disclosures is currently being assessed.

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 financial reporting for derivative instruments by requiring enhanced disclosure that enables investors to understand how and why an entity uses derivatives, how derivatives are accounted for and how derivative instruments affect an entity’s results of operations and financial position.




ANNUAL REPORT	OCTOBER 31, 2008	27

Notes to Financial Statements (continued)

In September 2008, FASB Staff Position No. 133-1 and FASB Interpretation No. 45-4 (the “FSP”), “Disclosures about Credit Derivatives and Certain Guarantees: An Amendment of FASB Statement No. 133 and FASB Interpretation No. 45; and Clarification of the Effective Date of FASB Statement No. 161” was issued and is effective for fiscal years and interim periods ending after November 15, 2008. The FSP amends FASB Statement No. 133, “Accounting for Derivative Instruments and Hedging Activities,” to require disclosures by sellers of credit derivatives, including credit derivatives embedded in hybrid instruments. The FSP also clarifies the effective date of FAS 161, whereby disclosures required by FAS 161 are effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. The impact on the Trusts’ 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 (“Independent Directors”) defer a portion of their annual complex-wide compensation. Deferred amounts earn an approximate return as though equivalent dollar amounts had been invested in common shares of other certain BlackRock Closed-End Funds selected by the Independent Directors. This has approximately the same economic effect for the Independent Directors as if the Independent Directors had invested the deferred amounts directly in other certain BlackRock Closed-End Funds.

The deferred compensation plan is not funded and obligations there under 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 Directors in order to match their 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 distributions 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.

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., to provide investment advisory and administration services. Merrill Lynch & Co., Inc. (“Merrill Lynch”) and The PNC Financial Services Group, Inc. are principal owners of BlackRock, Inc.

The Advisor is responsible for the management of 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 daily net assets, as follows:



			Monthly Fee

Investment Quality Municipal			0.35%
Municipal Income			0.60%
Long-Term Municipal			1.00%

For Investment Quality Municipal and Municipal Income, average daily net assets is the average daily value of the Trusts’ total assets minus the sum of its accrued liabilities. For Long-Term Municipal, average daily net assets is the average daily 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 average daily net assets as follows:



		Rate

Municipal Income Trust	July 31, 2008	0.15%
	July 31, 2009	0.10%
	July 31, 2010	0.05%

Long-Term Municipal	February 28, 2006 – February 28, 2011	0.40%
	February 28, 2012	0.30%
	February 28, 2013	0.20%
	February 28, 2014	0.10%

For the year ended October 31, 2008, the Advisor waived the fees, which is included on the Statements of Operations as fees waived by advisor, as follows:



Municipal Income	$	1,316,719
Long-Term Municipal	$	654,515

The Advisor has agreed to waive its advisory fees by the amount of investment 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 year ended October 31, 2008, the amounts were as follows:



Investment Quality Municipal	$	29,489
Municipal Income	$	51,023
Long-Term Municipal	$	5,235

The Advisor has entered into a separate sub-advisory agreement with BlackRock Financial Management, Inc. (“BFM”), an affiliate of the Advisor, with respect to each Trust, 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 daily net assets including proceeds from the issuance of Preferred Shares and TOBs.

For the year ended October 31, 2008, the Trusts reimbursed the Advisor for certain accounting services. The reimbursements, which are included in accounting services on the Statements of Operations, were as follows:



Municipal Income	$	12,913
Long-Term Municipal	$	5,494

Notes to Financial Statements (continued)

Pursuant to the terms of their custody agreements, fees may be reduced by amounts calculated on uninvested cash balances (“custody credits”), which are shown on the Statements of Operations as fees paid indirectly.

Certain officers and/or directors of the Trusts are officers and/or directors of BlackRock, Inc. 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 year ended October 31, 2008 were as follows:



	Purchases		Sales

Investment Quality Municipal	$	91,665,083	$	112,584,362
Municipal Income	$	122,028,168	$	173,140,092
Long-Term Municipal	$	49,587,132	$	131,246,312

4. Capital Share Transactions:

Common Shares

Investment Quality Municipal is authorized to issue 200,000,000 shares, including Preferred Shares, all of which were initially classified as Common Shares. There are an unlimited number of Common Shares authorized for Municipal Income and Long-Term Municipal. Each Trust’s Board is authorized, however, to reclassify any unissued shares without approval of holders of Common Shares. As of October 31, 2008, the shares owned by an affiliate of the Advisor of Long-Term Municipal were 9,704.

Common Shares issued and outstanding for the year ended October 31, 2008 and October 31, 2007 increased by the following amounts as a result of dividend reinvestment:



	Year Ended October 30, 2008		Year Ended October 31, 2007

Investment Quality Municipal		138,790		83,554
Municipal Income		152,320		197,269
Long-Term Municipal		—		36,210

Preferred Shares

The Preferred Shares are redeemable at the option of each Trust, in whole or in part, on any dividend payment date at $25,000 per share plus any accumulated unpaid dividends whether or not declared. The Preferred Shares are also subject to mandatory redemption at their liquidation preference plus any accumulated or 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 of Incorporation/Articles Supplementary, are not satisfied.

The holders of Preferred Shares have voting rights equal to the holders of Common Shares (one vote per share) and will vote together with holders of Common Shares (one vote per share) as a single class. However, 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 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 and effective yields at October 31, 2008:



	Series	Shares	Yields

Investment Quality Municipal	T-7	2,826	3.088	%
	T-28	2,252	3.088	%

Municipal Income	M-7	2,345	3.474	%
	T-7	2,345	3.087	%
	W-7	2,345	2.988	%
	R-7	2,345	2.999	%
	F-7	2,345	3.305	%

Dividends on seven-day Preferred Shares are cumulative at a rate which is reset every seven days based on the results of an auction. If the Preferred Shares fail to clear the auction on an auction date, the 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 the Preferred Shares is the higher of 110% of the AA commercial paper rate or 110% of 90% of the Kenny S&P 30-day High Grade Index rate divided by 1.00 minus the marginal tax rate. During the year ended October 31, 2008, the Preferred Shares of the Trusts were successfully remarketed at each remar-keting date until February 13, 2008. The low, high and average dividend rates on the Preferred Shares for each Trust for the year ended October 31, 2008 were as follows:



	Series	Low		High		Average

Investment Quality Municipal	T7	2.54	%	11.35	%	3.740	%
	T28	2.54	%	8.50	%	3.779	%

Municipal Income	M7	2.48	%	10.21	%	3.783	%
	T7	2.54	%	11.35	%	3.756	%
	W7	2.48	%	12.57	%	3.802	%
	R7	2.46	%	12.26	%	3.790	%
	F7	2.48	%	11.73	%	3.788	%

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 2.458% to 12.565%. 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 fund’s auction rate preferred shares than buyers. It is impossible to predict 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 its liquidation preference.



ANNUAL REPORT	OCTOBER 31, 2008	29



Notes to Financial Statements (continued)

A Trust 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%.

Each Trust pays commissions to certain broker-dealers at the end of each auction at an annual rate of 0.25%, calculated on the aggregate principal amount. For the year ended October 31, 2008, Merrill Lynch, Pierce, Fenner & Smith Incorporated, a wholly owned subsidiary of Merrill Lynch, earned commissions as follows:



	Commissions

Investment Quality Municipal	$	142,704
Municipal Income	$	145,453

On June 4, 2008, 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 dates:



	Series		Redemption Date		Shares Redeemed		Aggregate Principal

Investment Quality Municipal		T-7		6/25/2008		436	$	10,900,000
		T-28		7/09/2008		348	$	8,700,000

Municipal Income		M-7		6/24/2008		656	$	16,400,000
		T-7		6/25/2008		656	$	16,400,000
		W-7		6/26/2008		656	$	16,400,000
		R-7		6/27/2008		656	$	16,400,000
		F-7		6/30/2008		656	$	16,400,000

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

Preferred Shares issued and outstanding for the year ended October 31, 2007 remained constant for Investment Quality Municipal and Municipal Income.

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 on net asset values per share. The following permanent differences as of October 31, 2008 attributable to amortization methods on fixed income securities, non-deductible expenses and the reclassification of distributions were reclassified to the following accounts:



	Investment Quality Municipal			Municipal Income			Long-Term Municipal

Increase (decrease) paid-in capital	$	(3,510	)	$	(15,716	)		—
Increase (decrease) undistributed net investment income	$	(5,995	)	$	(39,791	)	$	8,138
Increase (decrease) accumulated net realized loss	$	9,505		$	55,507		$	(8,138	)

The tax character of distributions paid during the years ended October 31, 2008 and October 31, 2007 was as follows:



	Investment Quality Municipal		Municipal Income		Long-Term Municipal

Tax-Exempt income
10/31/08	$	19,993,104	$	51,795,142	$	8,807,259
10/31/07		22,514,181		56,847,893		9,535,364

Oridinary Income
10/31/08		306,274		1,544,313		541
10/31/07		—		75,424		—

Total
10/31/08	$	20,299,378	$	53,339,455	$	8,807,800

10/31/07	$	22,514,181	$	56,923,317	$	9,535,364

As of October 31, 2008, the tax components of accumulated losses were as follows:



	Investment Quality Municipal			Municipal Income			Long-Term Municipal

Undistributed tax-exempt income	$	805,827		$	1,725,552		$	1,608,424
Undistributed ordinary income		480,470			—			—
Capital loss carryforward		(5,295,272	)		(43,027,263	)		(22,753,957	)
Net unrealized losses*		(51,111,343	)		(141,283,030	)		(55,262,423	)

Total accumulated net losses	$	(55,120,318	)	$	(182,584,741	)	$	(76,407,956	)

The difference between book-basis and tax-basis net unrealized losses is attributable primarily to the tax deferral of losses on wash sales, the difference between book and tax amortization methods for premiums and discounts on fixed income securities, the book/tax differences in the accrual of income on securities in default, the deferral of compensation to directors, the difference between book and tax treatment of residual interests in tender option bond trusts, timing of income recognition from partnerships and other book/tax temporary differences.

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

Notes to Financial Statements (concluded)

6. Concentration Risk:

Each Trust’s investments are concentrated in certain states, which may be affected by adverse financial, social, environmental, economic, regulatory and political factors.

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

7. Subsequent Events:

The Trusts paid a net investment income dividend to Common Shareholders in the following amounts per share on December 1, 2008 to shareholders of record on November 14, 2008:



	Per Share Amount

Investment Quality Municipal	$	0.0630
Municipal Income	$	0.0686
Long-Term Municipal	$	0.0550

The dividends declared on Preferred Shares for the period November 1, 2008 to November 30, 2008 for the Trusts were as follows:



	Series		Dividends Declared

Investment Quality Municipal		T7	$	143,504

Municipal Income		M7	$	88,035
		T7	$	84,757
		W7	$	83,597
		R7	$	81,770
		F7	$	84,084

On September 15, 2008, Bank of America Corporation announced that it has agreed to acquire Merrill Lynch, one of the principal owners of BlackRock, Inc. The purchase has been approved by the shareholders and directors of both companies and certain regulators. Subject to other regulatory approvals, the transaction is expected to close on or about December 31, 2008.

In December 2008, commissions paid to broker-dealers on preferred shares that experience a failed auction were reduced to 0.15% on the aggregate principal amount. The Trusts will continue to pay commissions of 0.25% on the aggregate principal amount of all shares that successfully clear their auctions.

These financial statements and financial highlights are the responsibility of the Trusts’ management.

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 reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the 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 significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures include confirmation of securities owned as of October 31, 2008, 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 Municipal Income Trust, and BlackRock Long-Term Municipal Advantage Trust as of October 31, 2008, the results of their operations and the cash flows for BlackRock Long-Term Municipal Advantage Trust for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Disclosure of Investment Advisory Agreement and Subadvisory Agreement

The Board of Trustees or the Board of Directors, as the case may be (collectively, the “Board,” the members of which are referred to as “Directors”), of the BlackRock Investment Quality Municipal Trust, Inc. (“BKN”), BlackRock Municipal Income Trust (“BFK”) and BlackRock Long-Term Municipal Advantage Trust (“BTA,” and together with BKN and BFK, the “Funds”) met in April and May 2008 to consider approving the continuation of each Fund’s investment advisory agreement (each, an “Advisory Agreement”) with BlackRock Advisors, LLC (the “Advisor”), each Fund’s investment advisor. The Board also considered the approval of each Fund’s subadvisory agreement (each, a “Subadvisory Agreement” and, together with the “Advisory Agreement,” the “Agreements”) between the Advisor and BlackRock Financial Management, Inc. (the “Subadvisor”). The Advisor and the Subadvisor are collectively referred to herein as the “Advisors” and, together with BlackRock, Inc., “BlackRock.”

Activities and Composition of the Board

The Board of each Fund consists of thirteen individuals, eleven of whom are not “interested persons” of the Funds as defined in the Investment Company Act of 1940 (the “1940 Act”) (the “Independent Directors”). The Directors are responsible for the oversight of the operations of the Funds and perform the various duties imposed on the directors of investment companies by the 1940 Act. The Independent Directors have retained independent legal counsel to assist them in connection with their duties. The Chairman of the Board is an Independent Director. The Board has established four standing committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee and a Performance Oversight Committee.

Advisory Agreement and Subadvisory Agreement

Upon the consummation of the combination of BlackRock, Inc.’s investment management business with Merrill Lynch & Co., Inc.’s investment management business, including Merrill Lynch Investment Managers, L.P., and certain affiliates, each Fund entered into an Advisory Agreement and a Subadvisory Agreement, each with an initial two-year term. Consistent with the 1940 Act, after the Advisory Agreement’s and Subadvisory Agreement’s respective initial two-year term, the Board is required to consider the continuation of each Fund’s Advisory Agreement and Subadvisory Agreement on an annual basis. In connection with this process, the Board assessed, among other things, the nature, scope and quality of the services provided to each Fund by the personnel of BlackRock and its affiliates, including investment advisory services, administrative services, secondary market support services, oversight of fund accounting and custody, and assistance in meeting legal and regulatory requirements. The Board also received and assessed information regarding the services provided to each Fund by certain unaffiliated service providers.

Throughout the year, the Board also considered a range of information in connection with its oversight of the services provided by BlackRock and its affiliates. Among the matters the Board considered were: (a) investment performance for one-, three- and five-year periods, as applicable, against peer funds, as well as senior management and portfolio managers’ analysis of the reasons for underperformance, if applicable; (b) fees, including advisory, administration and other fees paid to BlackRock and its affiliates by each Fund, as applicable; (c) Fund operating expenses paid to third parties; (d) the resources devoted to and compliance reports relating to each Fund’s investment objective, policies and restrictions; (e) each Fund’s compliance with its Code of Ethics and compliance policies and procedures; (f) the nature, cost and character of non-investment management services provided by BlackRock and its affiliates; (g) BlackRock’s and other service providers’ internal controls; (h) BlackRock’s implementation of the proxy voting guidelines approved by the Board; (i) execution quality; (j) valuation and liquidity procedures; and (k) reviews of BlackRock’s business, including BlackRock’s response to the increasing scale of its business.

Board Considerations in Approving the Advisory Agreement and Subadvisory Agreement

To assist the Board in its evaluation of the Agreements, the Directors received information from BlackRock in advance of the April 22, 2008 meeting which detailed, among other things, the organization, business lines and capabilities of the Advisors, including: (a) the responsibilities of various departments and key personnel and biographical information relating to key personnel; (b) financial statements for BlackRock; (c) the advisory and/or administrative fees paid by each Fund to the Advisors, including comparisons, compiled by Lipper Inc. (“Lipper”), an independent third party, with the management fees, which include advisory and administration fees, of funds with similar investment objectives (“Peers”); (d) the profitability of BlackRock and certain industry profitability analyses for advisors to registered investment companies; (e) the expenses of BlackRock in providing various services; (f) non-investment advisory reimbursements, if applicable, and “fallout” benefits to BlackRock; (g) economies of scale, if any, generated through the Advisors’ management of all of the BlackRock closed-end funds (the “Fund Complex”); (h) the expenses of each Fund, including comparisons of each such Fund’s expense ratios (both before and after any fee waivers) with the expense ratios of its Peers; (i) an internal comparison of management fees classified by Lipper, if applicable; and (j) each Fund’s performance for the past one-, three- and five-year periods, as applicable, as well as each Fund’s performance compared to its Peers.

The Board also considered other matters it deemed important to the approval process, where applicable, such as payments made to BlackRock or its affiliates relating to the distribution of Fund shares, services related to the valuation and pricing of Fund portfolio holdings, and direct and indirect benefits to BlackRock and its affiliates from their relationship with the Funds.

In addition to the foregoing materials, independent legal counsel to the Independent Directors provided a legal memorandum outlining, among other things, the duties of the Board under the 1940 Act, as well as the general principles of relevant law in reviewing and approving advisory contracts, the requirements of the 1940 Act in such matters, an advisor’s fiduciary duty with respect to advisory agreements and compensation, and the standards used by courts in determining whether investment company boards of directors have fulfilled their duties and the factors to be considered by boards in voting on advisory agreements.



34	ANNUAL REPORT	OCTOBER 31, 2008




Disclosure of Investment Advisory Agreement and Subadvisory Agreement (continued)

The Independent Directors reviewed this information and discussed it with independent legal counsel prior to the meeting on April 22, 2008. At the Board meeting on April 22, 2008, BlackRock made a presentation to and responded to questions from the Board. Following the meeting on April 22, 2008, the Board presented BlackRock with questions and requests for additional information. BlackRock responded to these requests with additional written materials provided to the Directors prior to the meetings on May 29 and 30, 2008. At the Board meetings on May 29 and 30, 2008, BlackRock responded to further questions from the Board. In connection with BlackRock’s presentations, the Board considered each Agreement and, in consultation with independent legal counsel, reviewed the factors set out in judicial decisions and Securities and Exchange Commission (“SEC”) statements relating to the renewal of the Agreements.

Matters Considered by the Board

In connection with its deliberations with respect to the Agreements, the Board considered all factors it believed relevant with respect to each Fund, including the following: the nature, extent and quality of the services provided by the Advisors; the investment performance of each Fund; the costs of the services to be provided and profits to be realized by the Advisors and their affiliates from their relationship with the Funds; the extent to which economies of scale would be realized as the Fund Complex grows; and whether BlackRock realizes other benefits from its relationship with the Funds.

A. Nature, Extent and Quality of the Services: In evaluating the nature, extent and quality of the Advisors’ services, the Board reviewed information concerning the types of services that the Advisors provide and are expected to provide to each Fund, narrative and statistical information concerning each Fund’s performance record and how such performance compares to each Fund’s Peers, information describing BlackRock’s organization and its various departments, the experience and responsibilities of key personnel and available resources. The Board noted the willingness of the personnel of BlackRock to engage in open, candid discussions with the Board. The Board further considered the quality of the Advisors’ investment process in making portfolio management decisions.

In addition to advisory services, the Directors considered the quality of the administrative and non-investment advisory services provided to the Funds. The Advisors and their affiliates provided each Fund with such administrative and other services, as applicable (in addition to any such services provided by others for the Funds), and officers and other personnel as are necessary for the operations of the respective Fund. In addition to investment management services, the Advisors and their affiliates provided each Fund with services such as: preparing shareholder reports and communications, including annual and semi-annual financial statements and the Funds’ websites; communications with analysts to support secondary market trading; assisting with daily accounting and pricing; preparing periodic filings with regulators and stock exchanges; overseeing and coordinating the activities of other service providers; administering and organizing Board meetings and preparing the Board materials for such meetings; providing legal and compliance support (such as helping to prepare proxy statements and responding to regulatory inquiries); and performing other Fund administrative tasks necessary for the operation of the respective Fund (such as tax reporting and fulfilling regulatory filing requirements). The Board considered the Advisors’ policies and procedures for assuring compliance with applicable laws and regulations.

B. The Investment Performance of the Funds and BlackRock: As previously noted, the Board received performance information regarding each Fund and its Peers. Among other things, the Board received materials reflecting each Fund’s historic performance and each Fund’s one-, three- and five-year total returns (as applicable) relative to its Peers (including the Peers’ median performance). The Board was provided with a description of the methodology used by Lipper to select each Fund’s Peers. The Board noted that it regularly reviews the performance of each Fund throughout the year. The Board reviewed a narrative and statistical analysis of the Lipper data that was prepared by BlackRock, which analyzed various factors that affect Lipper rankings.

The Board noted that although BKN underperformed its Peers in at least two of the one-, three- and five-year periods reported, it outperformed its Peers in a subset of the Lipper universe in at least two of such periods based on a customized performance comparison provided by BlackRock which gives a greater significance to current distributions, providing a more accurate comparison.

The Board noted that in general BFK performed better than its Peers in that its performance was at or above the median of its Peers in at least two of the one-, three- and five-year periods reported.

The Board noted that although BTA underperformed its Peers in the one-year and since inception periods reported, it outperformed its Peers in a subset of the Lipper universe in the one-year period based on a customized performance comparison provided by BlackRock which gives a greater significance to current distributions, providing a more accurate comparison.

C. Consideration of the Advisory Fees and the Cost of the Services and Profits to be Realized by BlackRock and its Affiliates from their Relationship with the Funds: In evaluating the management fees and expenses that each Fund is expected to bear, the Board considered each Fund’s current management fee structure and each Fund’s expense ratios in absolute terms as well as relative to the fees and expense ratios of its applicable Peers. The Board, among other things, reviewed comparisons of each Fund’s gross management fees before and after any applicable reimbursements and fee waivers and total expense ratios before and after any applicable waivers with those of applicable Peers. The Board also reviewed a narrative analysis of the Peer rankings prepared by Lipper and summarized by BlackRock at the request of the Board. This summary placed the Peer rankings into context by analyzing various factors that affect these comparisons.

The Board noted that BKN paid contractual management fees lower than or equal to the median contractual fees paid by the Fund’s Peers. This comparison was made without giving effect to any expense reimbursements or fee waivers.



ANNUAL REPORT	OCTOBER 31, 2008	35




Disclosure of Investment Advisory Agreement and Subadvisory Agreement (concluded)

The Board noted that, although BFK paid contractual management fees higher than the median of its Peers, such fees were no more than 5 basis points greater than the median amount and therefore considered not to be materially higher than that of its Peers. This comparison was made without giving effect to any expense reimbursements or fee waivers.

The Board noted that although BTA paid contractual management fees higher than the median of its Peers, its actual management fees were below the median of its Peers.

The Board also compared the management fees charged and services provided by the Advisors to closed-end funds in general versus other types of clients (such as open-end investment companies and separately managed institutional accounts) in similar investment categories. The Board noted certain differences in services provided and costs incurred by the Advisor with respect to closed-end funds compared to these other types of clients and the reasons for such differences.

In connection with the Board’s consideration of the fees and expense information, the Board reviewed the considerable investment management experience of the Advisors and considered the high level of investment management, administrative and other services provided by the Advisors.

D. Profitability of BlackRock: The Board also considered BlackRock’s profitability in conjunction with its review of fees. The Board reviewed BlackRock’s profitability with respect to the Fund Complex and other fund complexes managed by the Advisors. In reviewing profitability, the Board recognized that one of the most difficult issues in determining profitability is establishing a method of allocating expenses. The Board also reviewed BlackRock’s assumptions and methodology of allocating expenses, noting the inherent limitations in allocating costs among various advisory products. The Board also recognized that individual fund or product line profitability of other advisors is generally not publicly available.

The Board recognized that profitability may be affected by numerous factors including, among other things, the types of funds managed, expense allocations and business mix, and therefore comparability of profitability is somewhat limited. Nevertheless, to the extent available, the Board considered BlackRock’s operating margin compared to the operating margin estimated by BlackRock for a leading investment management firm whose operations consist primarily of advising closed-end funds. The comparison indicated that BlackRock’s operating margin was approximately the same as the operating margin of such firm.

In evaluating the reasonableness of the Advisors’ compensation, the Board also considered any other revenues paid to the Advisors, including partial reimbursements paid to the Advisors for certain non-investment advisory services, if applicable. The Board noted that these payments were less than the Advisors’ costs for providing these services. The Board also considered indirect benefits (such as soft dollar arrangements) that the Advisors and their affiliates are expected to receive, which are attributable to their management of the Fund.

E. Economies of Scale: In reviewing each Fund’s fees and expenses, the Board examined the potential benefits of economies of scale, and whether any economies of scale should be reflected in the Fund’s fee structure, for example through the use of breakpoints for the Fund or the Fund Complex. In this regard, the Board reviewed information provided by BlackRock, noting that most closed-end fund complexes do not have fund-level breakpoints because closed-end funds generally do not experience substantial growth after their initial public offering and each fund is managed independently consistent with its own investment objectives. The Board noted that only three closed-end funds in the Fund Complex have breakpoints in their fee structures. Information provided by Lipper also revealed that only one closed-end fund complex used a complex-level breakpoint structure. The Board found, based on its review of comparable funds, that each Fund’s management fee is appropriate in light of the scale of the respective Fund.

F. Other Factors: In evaluating fees, the Board also considered indirect benefits or profits the Advisors or their affiliates may receive as a result of their relationships with the Funds (“fall-out benefits”). The Directors, including the Independent Directors, considered the intangible benefits that accrue to the Advisors and their affiliates by virtue of their relationships with the Funds, including potential benefits accruing to the Advisors and their affiliates as a result of participating in offerings of the Funds’ shares, potentially stronger relationships with members of the broker-dealer community, increased name recognition of the Advisors and their affiliates, enhanced sales of other investment funds and products sponsored by the Advisors and their affiliates and increased assets under management which may increase the benefits realized by the Advisors from soft dollar arrangements with broker-dealers. The Board also considered the unquantifiable nature of these potential benefits.

Conclusion with Respect to the Agreements

In reviewing and approving the continuation of the Agreements, the Directors did not identify any single factor discussed above as all-important or controlling, but considered all factors together, and different Directors may have attributed different weights to the various factors considered. The Independent Directors were also assisted by the advice of independent legal counsel in making this determination. The Directors, including the Independent Directors, unanimously determined that each of the factors described above, in light of all the other factors and all of the facts and circumstances applicable to each respective Fund, was acceptable for each Fund and supported the Directors’ conclusion that the terms of each Agreement were fair and reasonable, that each Fund’s fees are reasonable in light of the services provided to the respective Fund and that each Agreement should be approved.



36	ANNUAL REPORT	OCTOBER 31, 2008




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. 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 nominee) by the Plan Agent, which serves as agent for the shareholders in administering 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 brokerage 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 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 dividends and distributions. The automatic reinvestment of dividends and distributions 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 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.

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 SEC the certification of its chief executive officer and chief financial officer required by section 302 of the Sarbanes-Oxley Act.

Availability of Quarterly 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. Each Trust’s Forms N-Q are available on the SEC’s website at http://www.sec.gov and may also be reviewed and copied at the SEC’s Public Reference Room in Washington, DC.

Information on the operation of the Public Reference Room may be obtained by calling (800) SEC-0330. Each Trust’s Forms N-Q may also be obtained upon request and without charge by calling (800) 441-7762.

Electronic Delivery

Electronic copies of most financial reports are available on the Trusts’ website or shareholders can sign up for e-mail notifications of quarterly statements, annual and semi-annual reports and prospectuses 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.

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’ offerings 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.

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 it is intended to reduce expenses and eliminate duplicate mailings of shareholder documents. Mailings of your shareholder documents may be householded indefinitely unless you instruct us otherwise. If you do not want the mailing of these documents to be combined with those for other members of your household, please contact the Trusts at (800) 441-7762

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

Additional Information (concluded)

Articles Supplementary/Statement of Preferences

Effective May 30, 2008, following approval by the Trusts’ Board and the applicable ratings agencies, each Trust’s Articles Supplementary or Statement of Preferences, as applicable, was amended in order to facilitate the redemption of the Trusts’ Preferred Shares. The following sentence was added to the optional redemption section of the Statement of Preferences of Municipal Income and Long-Term Municipal:

For the purposes of this section, the term “liquid securities” shall include:

(i) any committed financing pursuant to a credit agreement, reverse repurchase agreement facility or similar credit arrangement, in each case which makes available to the Trust, no later than the day preceding the applicable redemption date, cash in an amount not less than the aggregate amount due to holders by reason of the redemption of their shares of Preferred Shares on such redemption date; and (ii) cash amounts due and payable to the Trust out of a sale of its securities if such cash amount is not less than the aggregate amount due to holders by reason of the redemption of their shares of Preferred Shares on such redemption date and such sale will be settled not later than the day preceding the applicable redemption date.

Effective September 13, 2008, following approval by the Trusts’ Board and the applicable rating agencies, the Board amended the terms of the Trusts’ Preferred Shares in order to allow the Trusts to enter into TOB transactions, the proceeds of which were used to redeem a portion of the Trusts’ Preferred Shares. Accordingly, the definition of Inverse Floaters was amended to incorporate the Trusts’ permissible ratio of floating rate instruments into inverse floating rate instruments. Additionally, conforming changes and certain formula modifications concerning inverse floaters were made to the definitions of Moody’s Discount Factor and S&P Discount Factor, as applicable, to integrate the Trusts’ investments in TOBs into applicable calculations.
