A Letter to Shareholders

Dear Shareholder

Financial markets weathered intense bouts of volatility in 2007, only to enter 2008 with no relief. January and February proved to be trying months for equities, but strong ones for some areas of the bond market, as fears of an economic recession swelled. The Federal Reserve Board (the “Fed”), after cutting the target federal funds rate 100 basis points (1%) between September 2007 and year-end, more than matched those cuts in January alone. Responding to a slowing economy and continued fallout from chaos in the credit markets, the Fed cut interest rates 75 basis points in a rare unscheduled session on January 22, and followed with a 50-basis-point cut at its regular meeting on January 30. Another 75-basis-point cut on March 18 brought the target rate to 2.25%.

Reverberations from the U.S. subprime mortgage collapse, and the associated liquidity and credit crisis, continue to permeate global financial markets. The S&P 500 Index of U.S. stocks was down in February, marking the fourth consecutive month of negative returns. International markets, while not unscathed, generally have outperformed their U.S. counterparts so far in 2008. Emerging markets, benefiting from stronger economic growth rates, have done particularly well.

In fixed income markets, fears related to the economic slowdown and related credit crisis have led to a prolonged flight to quality. Investors have largely shunned bonds associated with the housing and credit markets in favor of higher-quality government issues. The yield on 10-year Treasury issues, which touched 5.30% in June 2007 (its highest level in five years), fell to 4.04% by year-end and to 3.53% by the end of February, while prices correspondingly rose. After setting a new-issuance record in 2007, supply in the municipal bond market has been on the decline for four consecutive months (measured year over year). The market has struggled with concerns around the creditworthiness of monoline bond insurers and the failure of auctions for auction rate securities, driving yields higher and prices lower across the curve. By period-end, municipal bonds were trading at higher yields than their Treasury counterparts, a very unusual occurrence by historical standards.

Against this backdrop, the major benchmark indexes posted mixed results for the current reporting period, generally reflecting heightened investor risk aversion:


Total Returns as of February 29, 2008	6-month		12-month

U.S. equities (S&P 500 Index)	-8.79	%	-3.60	%

Trust Summary as of February 29, 2008 (Unaudited)	BlackRock Insured Municipal Income Trust



Investment Objective


	BlackRock Insured Municipal Income Trust (BYM) seeks to provide high current income exempt from regular federal income taxes. The Trust will invest at least 80% of its total assets in municipal obligations that are insured as to the timely payment of both principal and interest.

Performance


	For the six months ended February 29, 2008, the Trust returned -4.92% based on market price, with dividends reinvested. The Trust’s return based on net asset value (“NAV”) was -9.04%, with dividends reinvested, while the Lipper Insured Municipal Debt Funds (Leveraged) category posted an average return of -6.11% on an NAV basis. The Trust’s performance was negatively impacted by three primary factors: exposure to the long end of the municipal curve, which underperformed as the curve steepened significantly; a widening in credit spreads and insured credit spreads with weaker underlying ratings; and the massive underperformance of municipal cash relative to the Trust’s Bond Market Association hedges. The entire municipal insurance industry experienced unprecedented stress during the period, leading to their first-ever downgrades. Many of the problems caused by the stress on the insurers remained unresolved at period-end.

Trust Summary as of February 29, 2008 (Unaudited)	BlackRock Municipal Bond Trust



Investment Objective


	BlackRock Municipal Bond Trust (BBK) seeks to provide current income exempt from regular federal income taxes. Under normal market conditions, the Trust will invest at least 80% of its total assets in municipal bonds that are investment grade quality, or determined by the Trust’s investment advisor to be of equivalent credit quality at time of purchase. The Trust may invest up to 20% of its total assets in municipal bonds that are rated, at the time of investment, Ba/BB or B by Moody’s, S&P or Fitch or that are unrated but judged to be of comparable quality by BlackRock.

Performance


	For the six months ended February 29, 2008, the Trust returned -6.38% based on market price, with dividends reinvested. The Trust’s return based on NAV was -9.14%, with dividends reinvested. For the same period, the Lipper General Municipal Debt Funds (leveraged) category posted an average return of -6.37% on a NAV basis. The Trust’s performance was negatively impacted by exposure to capital appreciation bonds, as well as lower-rated and non-rated credits. Both areas suffered in a market environment characterized by rising long-term rates and substantially wider credit spreads. An above-average dividend yield helped to mitigate these negative influences somewhat.

BlackRock California Insured Municipal Income Trust (BCK) seeks to provide high current income exempt from regular federal income taxes and California income taxes. The Trust will invest at least 80% of its total assets in municipal obligations that are insured as to the timely payment of both principal and interest.

Performance

For the six months ended February 29, 2008, the Trust returned -5.85% based on market price, with dividends reinvested. The Trust’s return based on NAV was -8.93%, with dividends reinvested. For the same period, the Lipper California Insured Municipal Debt Funds category posted an average return of -6.64% on a NAV basis. The Trust’s performance was impacted by two key factors: exposure to the long end of the municipal yield curve, which underperformed as the curve steepened; and pressure on municipal bond insurers, which affected the entire insured municipal marketplace. The Trust’s underweight of lower-rated credits was a negative factor as insured bonds lost any premium value.

The Trust’s performance was affected by several key factors: exposure to the long end of the municipal yield curve, which, along with discount-coupon bonds, underperformed as the curve steepened; a widening in credit spreads, which negatively impacted uninsured credits in the portfolio; pressure on municipal bond insurers, which affected the entire insured municipal marketplace; and hedge positions, which contributed positively given their low correlation to the factors causing municipal underperformance.

The Benefits and Risks of Leveraging

BlackRock Insured Municipal Income Trust (“Insured Municipal”), BlackRock California Insured Municipal Income Trust (“California Insured”), BlackRock Florida Insured Municipal Income Trust (“Florida Insured”), BlackRock New York Insured Municipal Income Trust (“New York Insured”), BlackRock Municipal Bond Trust (“Municipal Bond”), BlackRock California Municipal Bond Trust (“California Bond”), BlackRock Florida Municipal Bond Trust (“Florida Bond”), BlackRock Maryland Municipal Bond Trust (“Maryland Bond”), BlackRock New Jersey Municipal Bond Trust (“New Jersey Bond”), BlackRock New York Municipal Bond Trust (“New York Bond”), BlackRock Virginia Municipal Bond Trust (“Virginia Bond”), BlackRock Municipal Interest Trust II (“Municipal Income II”), BlackRock California Municipal Income Trust II (“California Income II”), and BlackRock New York Municipal Income Trust II (“New York Income II”) (each a “Trust” and collectively the “Trusts”) utilize leverage to seek to enhance the yield and net asset value of its Common Shares. However, these objectives cannot be achieved in all interest rate environments. To leverage, the Trusts issue Preferred Shares, which pay dividends at prevailing short-term interest rates, and invest the proceeds in long-term municipal bonds. The interest earned on these investments, net of dividends to Preferred Shares, is paid to Common Shareholders in the form of dividends, and the value of each Trust’s holdings is reflected in the per share net asset value of the Trusts’ Common Shares. However, in order to benefit Common Shareholders, the yield curve must be positively sloped; that is, short-term interest rates must be lower than long-term interest rates. At the same time, a period of generally declining interest rates will benefit Common Shareholders. If either of these conditions change, then the risks of leveraging will begin to outweigh the benefits.

To illustrate these concepts, assume a trust’s Common Shares capitalization of $100 million and the issuance of 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 approximately 3% and long-term interest rates are approximately 6%, the yield curve has a strongly positive slope. 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 interest rates. Of course, increases in short-term interest rates would reduce (and even eliminate) the dividends on the Common Shares.

In this case, the dividends paid to Preferred Shareholders are significantly lower than the income earned on the trust’s long-term investments and, therefore, the Common Shareholders are the beneficiaries of the incremental 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. At the same time, the market value of the trust’s Common Shares (that is, its price as listed on the New York Stock Exchange or American Stock Exchange) may, as a result, decline. Furthermore, if long-term interest rates rise, the Common Shares’ net asset value will reflect the full decline in the price of the portfolio’s investments, since the value of the Trusts’ Preferred Shares does not fluctuate. In addition to the decline in net asset value, the market value of the trust’s Common Shares may also decline.

As of February 29, 2008 each Trust had the following leverage amounts, due to Preferred Shares, of managed assets before the deduction of Preferred Shares as follows:



	Leverage %

Insured Municipal	40	%
Municipal Bond	39	%
Municipal Income II	40	%
California Insured	40	%
California Bond	38	%
California Income II	40	%
Florida Insured	39	%
Florida Bond	38	%
Maryland Bond	39	%
New Jersey Bond	39	%
New York Insured	40	%
New York Bond	38	%
New York Income II	40	%
Virginia Bond	37	%

As a part of its investment strategy, the Trusts may invest in certain securities whose potential income return is inversely related to changes in a floating interest rate (“inverse floaters”). In general, income on inverse floaters will decrease when short-term interest rates increase and increase when short-term interest rates decrease. Investments in inverse floaters may be characterized as derivative securities and may subject the Trusts to the risks of reduced or eliminated interest payments and losses of invested principal. In addition, inverse floaters have the effect of providing investment leverage and, as a result, the market value of such securities will generally be more volatile than that of fixed rate, tax-exempt securities. To the extent a Trust invests in inverse floaters, the market value of the Trust’s portfolio and net asset value of the Trust’s shares may also be more volatile than if the Trust did not invest in these securities.

Swap Agreements

The Trusts may invest in swap agreements, which are over-the-counter contracts in which one party agrees to make periodic payments based on the change in market value of a specified bond, basket of bonds, or index in return for periodic payments based on a fixed or variable interest rate or the change in market value of a different bond, basket of bonds or index. Swap agreements may be used to obtain exposure to a bond market without owning or taking physical custody of securities. Swap agreements involve the risk that the party with whom each Trust has entered into a swap will default on its obligation to pay the Trust and the risk that the Trust will not be able to meet its obligation to pay the other party to the agreement.

1. Significant Accounting Policies:

BlackRock Insured Municipal Income Trust (“Insured Municipal”), BlackRock California Insured Municipal Income Trust (“California Insured”), BlackRock Florida Insured Municipal Income Trust (“Florida Insured”), BlackRock New York Insured Municipal Income Trust (“New York Insured”) (collectively the “Insured Trusts”), BlackRock Municipal Bond Trust (“Municipal Bond”), BlackRock California Municipal Bond Trust (“California Bond”), BlackRock Florida Municipal Bond Trust (“Florida Bond”), BlackRock Maryland Municipal Bond Trust (“Maryland Bond”), BlackRock New Jersey Municipal Bond Trust (“New Jersey Bond”), BlackRock New York Municipal Bond Trust (“New York Bond”), BlackRock Virginia Municipal Bond Trust (“Virginia Bond”) (collectively the “Bond Trusts”), BlackRock Municipal Income Trust II (“Municipal Income II”), BlackRock California Municipal Income Trust II (“California Income II”) and BlackRock New York Municipal Income Trust II (“New York Income II”) (collectively the “Income II Trusts”) (all, collectively the “Trusts”) are organized as Delaware statutory trusts. Insured Municipal, Municipal Bond and Municipal Income II are registered as diversified, closed-end management investment companies under the Investment Company Act of 1940, as amended (the “1940 Act”). California Insured, California Bond, California Income II, Florida Insured, Florida Bond, Maryland Bond, New Jersey Bond, New York Insured, New York Bond, New York Income II and Virginia Bond are registered as non-diversified, closed-end management investment companies under the 1940 Act. 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 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, as appropriate (the “Trustees” or the “Board”). In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from bond dealers, market transactions in comparable investments and various relationships between investments. Financial futures contracts are traded on exchanges and are valued at their last sale price. Swap agreements are valued by quoted fair values received daily by the Trusts’ pricing service. Short-term securities may be 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, under the direction of, or in accordance with, a method approved by the Board as reflecting fair value (“Fair Value Assets”). When determining the price for Fair Value Assets, BlackRock Advisors, LLC (the “Advisor”), an indirect, wholly owned subsidiary of BlackRock, Inc., and/or sub-advisor seeks to determine the price that the Trusts 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 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 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.


•	Forward interest rate swaps - The Trusts may enter into forward interest rate swaps, which are over-the-counter (“OTC”) contracts. In a forward interest rate swap, the Trusts 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. Gains or losses are also realized upon termination of the swap agreements. Swaps are “marked to market” daily and changes in value are recorded as unrealized appreciation (depreciation). Risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts’ terms and the possible lack of liquidity with respect to the swap agreements. The Trusts generally intend to close each forward interest rate swap before the accrual date specified in the agreement and therefore avoid entering into the interest rate swap underlying each forward interest rate swap.

	The Trusts may utilize forward starting swaps for the purpose of reducing the interest rate sensitivity of the portfolio and decreasing the Trusts’ exposure to interest rate risk.

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 February 29, 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 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. The Trusts file 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 August 31, 2004 through August 31, 2006. The statutes of limitations on the Trusts’ state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Notes to Financial Statements (continued)

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. The Trusts amortize all premiums and discounts on debt securities.

Dividends and Distributions: Dividends from net investment income are declared daily 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.

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 statement disclosures, if any, is currently being assessed.

In addition, in February 2007, Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“FAS 159”), was issued and is effective for fiscal years beginning after November 15, 2007. Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007, provided the entity also elects to apply the provisions of FAS 157. FAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. FAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. The impact on the Trusts’ financial statement disclosures, if any, is currently being assessed.

Forward Commitments, When-Issued Delayed Delivery Securities: The Trusts may purchase securities on a when-issued basis and may purchase or sell securities on a forward commitment basis. Settlement of such transactions normally occurs within a month or more after the purchase or sale commitment is made. The Trusts may purchase securities under such conditions only with the intention of actually acquiring them, but may enter into a separate agreement to sell the securities before the settlement date. Since the value of securities purchased may fluctuate prior to settlement, the 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. Upon making a commitment to purchase a security on a when-issued basis, the Trusts will hold liquid assets worth at least the equivalent of the amount due.

Segregation: 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., when-issued securities or swaps), each Trust will, consistent with certain interpretive letters issued by the SEC, designate on its books and records cash or other liquid debt securities having a market value at least equal to the amount that would otherwise be required to be physically segregated.

Deferred Compensation and BlackRock Closed-End Share Equivalent Investment Plan: Under the deferred compensation plan approved by each Trust’s Board, non-interested 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. These amounts are included in other assets on the Statement of Assets and Liabilities. This has approximately the same economic effect for the Independent Trustees as if the Independent Trustees had invested the deferred amounts directly in other certain BlackRock Closed-End Funds.

The deferred compensation plan is not funded and obligations thereunder represent general unsecured claims against the general assets of the Trusts. 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.

Other: Expenses that are directly related to one of the Trusts or classes are charged to that Trust or class. Other operating expenses are pro-rated to certain Trusts on the basis of relative net assets.

Bank Overdraft: BlackRock Florida Insured Municipal Income Trust recorded a bank overdraft which resulted from management estimates of available cash.

2. Investment Advisory Agreement and Other Transactions with Affiliates:

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

The Advisor is responsible for the management of the Trusts’ portfolios and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Trusts. For such services, the Trusts pay the Advisor a monthly fee at an annual rate of 0.55% for the Insured Trusts and Income II Trusts and 0.65% for the Bond Trusts of the average weekly value of each Trust’s net assets including proceeds from the issuance of auction preferred shares, excluding investments in affiliated sweep vehicles. The Advisor has voluntarily agreed to waive a portion of the investment advisory fee. With respect to the Insured Trusts, the waiver, as a percentage of net assets including proceeds from the issuance of Preferred Shares, is as follows: 0.20% for the first five years of each Trust’s operations, 0.15% in year six, 0.10% in year seven, and 0.05% in year eight. With respect to the Bond Trusts, the waiver, as a percentage of net assets including proceeds from the issuance of Preferred Shares, is as follows: 0.30% for the first five years of each Trust’s operations, 0.25% in year six, 0.20% in year seven, 0.15% in year eight, 0.10% in year nine and 0.05% in year 10. With respect to the Income II Trusts, the waiver, as a percentage of net assets including proceeds from the issuance of Preferred Shares, is as follows: 0.15% for the first five years of each Trust’s operations, 0.10% in year six through year seven, and 0.05% in year eight through year 10.

In addition, the Advisor has entered into 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.

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

Certain officers and/or Trustees of the Trusts are officers and/or directors of BlackRock, Inc. or its affiliates.

Preferred Shares have a par value of $0.001 per share and a liquidation preference of $25,000 per share, plus accrued and unpaid dividends, that entitle their holders to receive cash dividends at an annual rate that may vary for the successive dividend periods. The yields in effect at February 29, 2008 were as follows:



	Series	Yield

Insured Municipal	M-7	4.188	%

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’s are 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 six months ended February 29, 2008, the Preferred Shares were successfully auctioned at each auction date until February 13, 2008. The low, high and average dividend range on the Preferred Shares for each of the Trusts for the six months ended February 29, 2008 were as follows:



	Series	Low		High		Average

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 would be less than 200%.

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 $25,000 per share 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 Declaration of Trust/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) and will vote together with holders of Common Shares 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 subclassification as a closed-end investment company or change its fundamental investment restrictions or (c) change its business so as to cease to be an investment company.

Since February 13, 2008, the Preferred Shares of the Trusts failed to clear any of its auctions. As a result, the Preferred Shares dividend rates were reset to the maximum applicable rate which ranged from 3.29% to 4.51%. A failed auction is not an event of default for the Trusts but it is a liquidity event for the holders of the Preferred Shares. Recent auction market liquidity problems have triggered numerous failed auctions for many closed-end funds, including BlackRock. A failed auction occurs when there are more sellers of a Trust’s auction rate preferred shares than buyers. It is impossible to predict how long this imbalance will last. An auction for each Trust’s Preferred Shares may not occur for a long period of time, if ever, and even if liquidity does resume, holders of the Preferred Shares may not have the amount of liquidity they desire or the ability to sell the Preferred Shares at par.

5. Capital Loss Carryforward

As of August 31, 2007, the Trusts had the following capital loss carryforwards available to offset future realized gains:



	Capital Loss Carryforward		Expires

Maryland Bond	$	27,007	2015

New York Income II	$	70,160	2015

Virginia Bond	$	45,800	2015

6. Concentration Risk:

The Trusts concentrate their investments in securities issued by state agencies, other governmental entities and U.S. Territories. The Trusts are more susceptible to adverse financial, social, environmental, economic, regulatory and political factors that may affect these states agencies, other governmental entities and U.S. Territories, which could seriously affect the ability of these states and their municipal subdivisions to meet continuing obligations for principle and interest payments and therefore could impact the value of the Trusts’ investments and net asset value per share, than if the Trusts were not concentrated in securities issued by state agencies, other governmental entities and U.S. Territories.

Many municipalities insure repayment for their obligations. Although bond insurance reduces the risk of loss due to default by an issuer, such bonds remain subject to the risk that market value may fluctuate for other reasons and there is no assurance that the insurance company will meet its obligations. These securities have been identified in the Schedules of Investments.

7. Subsequent Events:

Each Trust paid tax-exempt dividends per common share on April 1, 2008 to shareholders of record on March 14, 2008 in the following amounts:



	Common Dividend Per Share

Insured Municipal	$	.061000
Municipal Bond	$	.076500
Municipal Income II	$	.071000

Additional Information

Availability of Quarterly Schedule of Investments

Each Trust files their complete schedule of portfolio holdings with the Securities and Exchange Commission (“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 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.
