Over the past year, the bursting of the housing bubble and the resultant credit crisis mushroomed into an all-out global financial market meltdown, featuring the collapse of storied financial firms, volatile swings in the world's financial markets and monumental government responses designed to rescue the beleaguered financial system. The U.S. economy appeared relatively resilient through the first half of 2008, when rising food and energy prices stoked fears of inflation. The tenor changed dramatically in the second half, as inflation pressures subsided amid plummeting oil prices, but a uniform and rapid deterioration in key economic indicators darkened growth prospects. Just after the close of the reporting period, the National Bureau of Economic Research officially declared that the U.S. was in a recession, and that it had begun in December 2007. The Federal Reserve Board (the "Fed"), after slashing interest rates aggressively in the early months of the year, resumed that rate-cutting campaign in the fall, bringing the target federal funds rate to a record low range of between zero to 0.25% on December 16. More significant was the central bank's pledge that future policy moves to revive the global economy and financial markets would comprise primarily nontraditional and quantitative easing measures, such as capital injections, lending programs and government guarantees. Against this backdrop, U.S. equity markets experienced intense volatility, with periods of downward pressure punctuated by sharp rebounds. Losses were significant and broad-based, though non-U.S. markets decelerated at a considerably faster pace than domestic equities -- a stark reversal of prior 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 retreated to the safest and most liquid investments. Amid spillover from historic events in the financial sector, municipals contended with fewer market participants, lack of liquidity, a challenging funding environment and a backlog of new-issue supply, all of which contributed to the sector's underperformance relative to its taxable counterparts. Similarly, economic turmoil and badly broken 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. In all, an investor flight to safety prevailed, as evidenced in the six- and 12-month returns of the major benchmark indexes: Total Returns as of November 30, 2008 6-month 12-month ============================================================================================================== U.S. equities (S&P 500 Index) (35.20)% (38.09)% - -------------------------------------------------------------------------------------------------------------- Small cap U.S. equities (Russell 2000 Index) (36.26) (37.46) - -------------------------------------------------------------------------------------------------------------- International equities (MSCI Europe, Australasia, Far East Index) (44.92) (47.79) - -------------------------------------------------------------------------------------------------------------- U.S. Treasury securities (Merrill Lynch 10-Year U.S. Treasury Index) 11.62 12.69 - -------------------------------------------------------------------------------------------------------------- Taxable fixed income (Barclays Capital U.S. Aggregate Index*) 0.24 1.74 - -------------------------------------------------------------------------------------------------------------- Tax-exempt fixed income (Barclays Capital Municipal Bond Index*) (4.98) (3.61) - -------------------------------------------------------------------------------------------------------------- High yield bonds (Barclays Capital U.S. Corporate High-Yield 2% Issuer Capped Index*) (31.73) (30.49) - -------------------------------------------------------------------------------------------------------------- * Formerly a Lehman Brothers index.

Sincerely, /s/ Rob Kapito Rob Kapito President, BlackRock Advisors, LLC THIS PAGE NOT PART OF YOUR FUND REPORT 3 Fund Summary as of November 30, 2008 BlackRock California Insured Municipal Bond Fund Portfolio Management Commentary How did the Fund perform? o The Fund recently changed its fiscal year end to May 31. Fund returns for the six-month period ended November 30, 2008 lagged that of the Barclays Capital Municipal Bond Index and the Lipper Single-State Insured Municipal Debt Funds category average. Notably, the Lipper category consists of funds investing in insured municipal bonds issued by individual states other than California. As a result, Fund returns will vary from that of the broader Lipper peer group. What factors influenced performance? o The Fund's performance was negatively impacted as the market stripped insured bonds of their premium values in light of the troubles faced by the monoline insurers backing the bonds. The Fund maintained only a 2% exposure to inverse floaters, but this leveraged exposure underperformed, which also detracted from results. Finally, the Fund's holdings in zero-coupon bonds hurt performance, as these issues declined more than coupon bonds. o Given the declines in insured bonds, the Fund's relatively lower percentage of these securities helped performance somewhat. Another factor positively affecting Fund performance was a lack of exposure to uninsured California general obligation bonds during a period when concerns over state finances caused those bonds to underperform. Finally, the Fund benefited from a lack of hedging. Describe recent portfolio activity. o The Fund's cash reserves were kept at atypically high levels -- at times reaching 8% of total assets -- as we attempted to maintain a degree of liquidity in the Fund. Dislocations in the short-term tax-exempt market continued to provide opportunities for us to invest in weekly floating rate bonds with yields as high as 7% to 10%. Toward the end of the period, the Fund's duration was extended, partly as a result of duration extension that occurred throughout the market. We also extended duration with new purchases, as we took advantage of the heavy new-issue calendar and forced selling within the secondary market. Describe Fund positioning at period-end. o At period-end, the Fund's duration was slightly long. Approximately 84% of the Fund's assets was invested in insured securities; uninsured holdings comprised largely higher-quality issues. Less than 1% of the Fund's assets was invested in credits that were below investment grade. o The Fund's cash reserve position was nearly 9.5% of total assets. Markets remain extremely unsettled. We do not want to be forced to sell assets if redemptions accelerate around year-end, which would be typical. Moreover, an ample cash reserve affords the flexibility to bid for issues that we believe will add to the performance potential of the Fund when markets normalize in the future.

SEMI-ANNUAL REPORT NOVEMBER 30, 2008 5 Fund Summary as of November 30, 2008 BlackRock Florida Municipal Bond Fund Portfolio Management Commentary How did the Fund perform? o The Fund recently changed its fiscal year end to May 31. Fund returns for the six-month period ended November 30, 2008 lagged that of the Barclays Capital Municipal Bond Index and the Lipper Florida Municipal Debt Funds category average. While the Barclays Index measures the performance of municipal bonds nationally, the Lipper category consists of funds that limit their investment to securities exempt from taxation in Florida. What factors influenced performance? o The six-month period saw a tremendous amount of pressure applied to spread products throughout the municipal market, with outflows from high-yield funds hurting sectors such as corporate-backed, health care, land-secured, housing, tobacco and pre-paid gas bonds. More than half of the states in the U.S. experienced declining tax revenues and additional pressures from heightened market volatility, which resulted in spending cuts, tapping of reserves or raising of revenues in order to achieve balanced budgets. These problems are expected to continue into next year. As a result, municipal bonds ended the period offering higher yields than U.S. Treasury securities in all maturity ranges, a very unusual scenario. o The Fund's performance was negatively impacted by its positions in insured bonds, which were stripped of their premium values by the market in light of the troubles faced by the monoline insurers backing the bonds. The Fund's performance was also hindered by its positions in the health care, housing, land-secured and corporate-backed sectors. These sectors were adversely affected by high-yield fund outflows, as noted above, and by the poor performance of the overall U.S. economy. o One factor that contributed positively to the Fund's performance was its overweight position in pre-refunded securities. With so much uncertainty in the marketplace, investors responded with a very strong flight-to-quality that drove up demand for pre-refunded bonds. Describe recent portfolio activity. o The Fund's cash reserves were kept at atypically high levels -- at times reaching 5% of total assets -- as we attempted to maintain a degree of liquidity in the Fund. The Fund had outflows of approximately $25 million for the reporting period. Describe Fund positioning at period-end. o The Fund ended the reporting period with a neutral duration. We expect outflows from the Fund to continue, given the current investment climate.

SEMI-ANNUAL REPORT NOVEMBER 30, 2008 7 Fund Summary as of November 30, 2008 BlackRock New Jersey Municipal Bond Fund Portfolio Management Commentary How did the Fund perform? o The Fund recently changed its fiscal year end to May 31. Fund returns for the six-month period ended November 30, 2008 lagged that of the Barclays Capital Municipal Bond Index, but outperformed the Lipper New Jersey Municipal Debt Funds category average. While the Barclays Index measures the performance of municipal bonds nationally, the Lipper category consists of funds that limit their investment to securities exempt from taxation in New Jersey. What factors influenced performance? o The six-month period saw a tremendous amount of pressure applied to spread products throughout the municipal market, with outflows from high-yield funds hurting sectors such as corporate-backed, health care, land-secured, housing, tobacco and pre-paid gas bonds. More than half of the states in the U.S. experienced declining tax revenues and additional pressures from heightened market volatility, which resulted in spending cuts, tapping of reserves or raising of revenues in order to achieve balanced budgets. These problems are expected to continue into 2009. As a result, municipal bonds ended the period offering higher yields than U.S. Treasury securities in all maturity ranges, which is a very unusual scenario. o Two exceptions to the spread widening trend in the municipal market were pre-refunded bonds and essential purpose bonds rated AA and above. Due to the historically low returns on these bonds, we entered the period underweight in both sectors, which hurt the Fund's performance. Exposure to the underperforming housing and health care sectors further hampered results. o On the other hand, the Fund's slightly above-average distribution rate and neutral duration position benefited performance relative to the Lipper category average. Opportunistically selling into pockets of retail investor demand also proved advantageous. Describe recent portfolio activity. o Portfolio turnover was low throughout the six months, as market dislocations and liquidity pressures kept new issuance down in New Jersey. This lack of new-issue supply, combined with the depressed valuations of existing holdings, limited opportunities to restructure the portfolio. Trading activity consisted primarily of smaller sales where retail investor demand remained, as well as relative value trades. In making new purchases, we sought bonds with higher-quality underlying ratings. Describe Fund positioning at period-end. o The Fund ended the period with a neutral duration relative to its Lipper peer group. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions.

SEMI-ANNUAL REPORT NOVEMBER 30, 2008 9 Fund Summary as of November 30, 2008 BlackRock Pennsylvania Municipal Bond Fund Portfolio Management Commentary How did the Fund perform? o The Fund recently changed its fiscal year end to May 31. Fund returns for the six-month period ended November 30, 2008 lagged that of the Barclays Capital Municipal Bond Index, but outperformed the Lipper Pennsylvania Municipal Debt Funds category average. While the Barclays Index measures the performance of municipal bonds nationally, the Lipper category consists of funds that limit their investment to securities exempt from taxation in Pennsylvania. What factors influenced performance? o The six-month period saw a tremendous amount of pressure applied to spread products throughout the municipal market, with outflows from high-yield funds hurting sectors such as corporate-backed, health care, land-secured, housing, tobacco and pre-paid gas bonds. More than half of the states in the U.S. experienced declining tax revenues and additional pressures from heightened market volatility, which resulted in spending cuts, tapping of reserves or raising of revenues in order to achieve balanced budgets. These problems are expected to continue into next year. As a result, municipal bonds ended the period offering higher yields than U.S. Treasury securities in all maturity ranges, a very unusual scenario. o During the period, we actively moved the Fund's duration from a modestly long position to neutral, which benefited performance by cushioning the Fund from some of the negative price impact associated with rising rates in the tax-exempt market. o Despite the reduction in the Fund's duration, performance was negatively impacted by exposure to the long end of the municipal yield curve, which underperformed as the curve steepened. Fund performance was also hindered by a widening in credit spreads, which negatively impacted weaker credits. Describe recent portfolio activity. o Other than the duration adjustment, activity in the Fund was aimed primarily at improving credit quality and bond structures, which included buying bonds with higher coupons to improve the income component in the higher interest rate environment. Describe Fund positioning at period-end. o The Fund ended the period with a neutral duration, as well as a cash reserve of approximately 6% of total assets, which will be invested opportunistically as higher coupon new issues come to market.

SEMI-ANNUAL REPORT NOVEMBER 30, 2008 11 Fund Summary as of November 30, 2008 BlackRock Intermediate Municipal Fund Portfolio Management Commentary How did the Fund perform? o The Fund recently changed its fiscal year end to May 31. Fund returns for the six-month period ended November 30, 2008 lagged that of the Barclays Capital Municipal Bond Index and the Lipper Intermediate Municipal Debt Funds category average. o The Fund focuses its investments on the intermediate portion of the municipal yield curve; therefore, the Lipper category average provides a truer representation of the Fund's composition and a more comparable means for measurement. What factors influenced performance? o The six-month period saw a tremendous amount of pressure applied to spread products throughout the municipal market, with outflows from high-yield funds hurting sectors such as corporate-backed, health care, land-secured, housing, tobacco and pre-paid gas bonds. More than half of the states in the U.S. experienced declining tax revenues and additional pressures from heightened market volatility, which resulted in spending cuts, tapping of reserves or raising of revenues in order to achieve balanced budgets. These problems are expected to continue into 2009. As a result, municipal bonds ended the period offering higher yields than U.S. Treasury securities in all maturity ranges, which is a very unusual scenario. o Two exceptions to the spread widening trend in the municipal market were pre-refunded bonds and essential purpose bonds rated AA and above. Due to the historically low returns on these bonds, we entered the period underweight in both sectors, which hurt the Fund's performance. Exposure to the underperforming transportation and corporate-backed sectors further hampered results. o On the other hand, we maintained a slightly shorter duration versus the Lipper category average, which benefited performance during the period. Describe recent portfolio activity. o Portfolio turnover was low throughout the six months, as market dislocations and liquidity pressures kept new issuance down. This lack of new-issue supply, combined with the depressed valuations of existing holdings, limited opportunities to restructure the portfolio. Trading activity primarily comprised swapping out of lower-quality issues in favor of better-performing credits and sectors, as the market allowed. However, toward the end of the reporting period, even this selective upgrading was prohibited as the limited demand for higher yielding credits was overwhelmed by distressed sellers. Describe Fund positioning at period-end. o The Fund ended the period with a slightly shorter duration relative to its Lipper peer group. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions.

For All Funds Performance information reflects past performance and does not guarantee future results. Current performance may be lower or higher than the performance data quoted. Refer to www.blackrock.com/funds to obtain performance data current to the most recent month-end. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in each of the performance tables on pages 5, 7, 9, 11 and 13 assume reinvestment of all dividends and capital gain distributions, if any, at net asset value on the payable date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original costs. Dividends paid to each class of shares will vary because of the different levels of service, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders. For BlackRock California Insured Municipal Bond Fund, BlackRock New Jersey Municipal Bond Fund, BlackRock Pennsylvania Municipal Bond Fund and BlackRock Intermediate Municipal Fund, the Funds' Advisor agreed to reimburse a portion of their fee. Without such reimbursement, the Funds' performance would have been lower. SEMI-ANNUAL REPORT NOVEMBER 30, 2008 15 Disclosure of Expenses Shareholders of each Fund may incur the following charges: (a) expenses related to transactions, including sales charges, redemption fees and exchange fees; and (b) operating expenses, including advisory fees, distribution fees including 12b-1 fees, and other Fund expenses. The expense examples on pages 16 - 19 (which are based on a hypothetical investment of $1,000 invested on June 1, 2008 and held through November 30, 2008) are intended to assist shareholders both in calculating expenses based on an investment in each Fund and in comparing these expenses with similar costs of investing in other mutual funds. The tables provide information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number corresponding to their share class under the heading entitled "Expenses Paid During the Period." The tables also provide information about hypothetical account values and hypothetical expenses based on each Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in these Funds and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in other funds' shareholder reports. The expenses shown in the tables are intended to highlight shareholders' ongoing costs only and do not reflect any transactional expenses, such as sales charges, redemption fees or exchange fees. Therefore, the hypothetical examples are useful in comparing ongoing expenses only, and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher.

Various inputs are used in determining the fair value of investments, which are as follows: o Level 1 -- price quotations in active markets/exchanges for identical securities o Level 2 -- other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, and default rates) or other market-corroborated inputs) o Level 3 -- unobservable inputs based on the best information available in the circumstance, to the extent observable inputs are not available (including the Fund's own assumption used in determining the fair value of investments) The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For information about the Fund's policy regarding valuation of investments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements. The following table summarizes the inputs used as of November 30, 2008 in determining the fair valuation of the Fund's investments: -------------------------------------------------------------------------- Investments in Valuation Inputs Securities -------------------------------------------------------------------------- Level 1 ................................................... $ 2,406,301 Level 2 ................................................... 254,347,861 Level 3 ................................................... -- -------------------------------------------------------------------------- Total $256,754,162 ============ See Notes to Financial Statements.

SEMI-ANNUAL REPORT NOVEMBER 30, 2008 81 Notes to Financial Statements (Unaudited) 1. Organization and Significant Accounting Policies: BlackRock California Insured Municipal Bond Fund of BlackRock California Municipal Series Trust, BlackRock Florida Municipal Bond Fund, BlackRock New Jersey Municipal Bond Fund and BlackRock Pennsylvania Municipal Bond Fund, each a series of BlackRock Multi-State Municipal Series Trust, and BlackRock Intermediate Municipal Fund, which is presently the only series of BlackRock Municipal Series Trust (referred to as the "Funds" or individually as the "Fund"), are registered under the Investment Company Act of 1940, as amended (the "1940 Act"). BlackRock California Insured Municipal Bond Fund and BlackRock Intermediate Municipal Fund are registered as diversified, open-end management investment companies. BlackRock Florida Municipal Bond Fund, BlackRock New Jersey Municipal Bond Fund and BlackRock Pennsylvania Municipal Bond Fund are registered as non-diversified, open-end management investment companies. BlackRock California Municipal Series Trust, BlackRock Multi-State Municipal Series Trust and BlackRock Municipal Series Trust are organized as Massachusetts business trusts. The Funds' 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 Fund offers multiple classes of shares. Institutional and Service Shares are sold only to certain eligible investors. Investor A Shares are generally sold with a front-end sales charge. Investor A1, Investor B, Investor B1 and Investor C1 Shares are not generally available except for dividend and capital gains reinvestment. Shares of Investor B, Investor B1, Investor C and Investor C1 may be subject to a contingent deferred sales charge. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Service, Investor A, Investor A1, Investor B, Investor B1, Investor C and Investor C1 Shares bear certain expenses related to the shareholder servicing of such shares, and Investor B, Investor B1, Investor C and Investor C1 Shares also bear certain expenses related to the distribution of such shares. Each class has exclusive voting rights with respect to matters relating to its shareholder servicing and distribution expenditures (except that Investor B and Investor B1 shareholders may vote on material changes to the Investor A and Investor A1 distribution plans). The following is a summary of significant accounting policies followed by the Funds: 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 Fund's Board of Trustees (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, pricing matrixes, market transactions in comparable investments and information with respect to various relationships between investments. Swap agreements are valued utilizing quotes received daily by each Fund's pricing service, or through brokers. Financial futures contracts traded on exchanges are valued at their last sale price. 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 the sub-advisor seeks to determine the price that each Fund might reasonably expect to receive from the current sale of that asset in an arm's-length transaction. Fair value determinations shall be based upon all available factors that the investment advisor and/or sub-advisor deems relevant. The pricing of all Fair Value Assets is subsequently reported to the Board or a committee thereof. Derivative Financial Instruments: The Funds may engage in various portfolio investment strategies to increase the return of the Funds 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 contract. o Financial futures contracts -- The Funds may purchase or sell financial futures contracts and options on financial futures contracts for investment purposes or to manage their 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 Funds agree to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as margin variation and are recognized by the Funds as unrealized gains or losses. When the contract is closed, the Funds record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. The use of 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. o Forward interest rate swaps -- The Funds may enter into forward interest rate swaps for investment purposes. In a forward interest rate swap, the Funds 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 Funds are recorded in the accompanying Statements of Operations as realized gains or losses, respectively. 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, the Funds will record a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Funds' basis 82 SEMI-ANNUAL REPORT NOVEMBER 30, 2008 Notes to Financial Statements (continued) 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 Funds 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. Forward Commitments and When-Issued Delayed Delivery Securities: The Funds 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 Funds 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 Funds may be required to pay more at settlement than the security is worth. In addition, the purchaser is not entitled to any of the interest earned prior to settlement. When purchasing a security on a delay-delivery basis, the Funds assume the rights and risks of ownership of the security, including the risk of price and yield fluctuations. Municipal Bonds Transferred to Tender Option Bond Trusts: The Funds 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 the Funds have 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 a Fund include the right of the Fund (1) to cause the holders of a proportional share of the floating rate certificates to tender their certificates at par, and (2) to transfer, within seven days, a corresponding share of the municipal securities from the TOB to the Funds. The cash received by the TOB from the sale of the short-term floating rate certificates, less transaction expenses, is paid to the Funds, which typically invests the cash in additional municipal securities. Each Fund's 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 Fund's Schedule of Investments and the proceeds from the transaction are reported as a liability for trust certificates. Interest income from the underlying security is recorded by the Funds 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 Funds. 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 November 30, 2008, the aggregate value of the underlying municipal securities transferred to TOBs, the related liability for trust certificates and the range of interest rates on the trust certificates were as follows: - -------------------------------------------------------------------------------- Underlying Municipal Liability Securities for Range of Transferred Trust Interest to TOBs Certificates Rates - -------------------------------------------------------------------------------- BlackRock California Insured Municipal Bond Fund ............ $16,710,409 $10,933,523 2.428% - 2.718% BlackRock Florida Municipal Bond Fund ...................... $ 5,164,413 $ 2,320,000 2.455% BlackRock New Jersey Municipal Bond Fund ............ $ 1,910,673 $ 1,075,000 2.988% - -------------------------------------------------------------------------------- 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 Funds' investment in TOBs likely will adversely affect the Funds' investment income and distributions to shareholders. Fluctuations in the market value of municipal securities deposited into the TOB may adversely affect the Funds' net asset values per share. Zero-Coupon Bonds: The Funds may invest in zero-coupon bonds, which are normally issued at a significant discount from face value and do not provide for periodic interest payments. Zero-coupon bonds may experience greater volatility in market value than similar maturity debt obligations which provide for regular interest payments. Segregation and Collateralization: In cases in which the 1940 Act and the interpretive positions of the Securities and Exchange Commission ("SEC") require that each Fund segregate assets in connection with certain investments (e.g., when-issued securities, financial futures contracts and swaps), each Fund 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 Funds may also be required to deliver or deposit securities as collateral for certain investments (e.g., financial futures contracts and swaps). SEMI-ANNUAL REPORT NOVEMBER 30, 2008 83 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 recorded on the accrual basis. The Funds amortize all premiums and discounts on debt securities. Income and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. 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. Income Taxes: It is the Funds' policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of their taxable income to their shareholders. Therefore, no federal income tax provision is required. The Funds 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 Funds' U.S. federal tax returns remains open for the years ended August 31, 2005 through August 31, 2007 for California Insured Municipal Bond Fund, July 31, 2005 through July 31, 2007 for Florida, New Jersey, and Pennsylvania Municipal Bond Funds, and October 31, 2005 through October 31, 2007 for Intermediate Municipal Fund. The statutes of limitations on the Funds' state and local tax returns may remain open for an additional year depending upon the jurisdiction. Recent Accounting Pronouncement: In March 2008, Statement of Financial Accounting Standards No. 161, "Disclosures about Derivative Instruments and Hedging Activities -- an amendment of FASB Statement No. 133" ("FAS 161"), was issued. FAS 161 is intended to improve 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. FAS 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. The impact on the Funds' financial statement disclosures, if any, is currently being assessed. Other: Expenses directly related to a Fund or its classes are charged to that Fund or class. Other operating expenses shared by several funds are pro-rated among those funds on the basis of relative net assets or other appropriate methods. Other expenses of the Funds are allocated daily to each class based on its relative net assets. 2. Investment Advisory Agreement and Other Transactions with Affiliates: Each Fund has entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the "Advisor"), an indirect, wholly owned subsidiary of BlackRock, Inc., to provide investment advisory and administration services. Merrill Lynch & Co., Inc. ("Merrill Lynch"), a wholly owned subsidiary of Bank of America Corporation ("BAC"), and The PNC Financial Services Group, Inc. ("PNC") are the largest stockholders of BlackRock, Inc. The Advisor is responsible for the Fund's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operation of the Funds. For such services, BlackRock California Insured Municipal Bond Fund, BlackRock Florida Municipal Bond Fund, BlackRock New Jersey Municipal Bond Fund and BlackRock Pennsylvania Municipal Bond Fund pay the Advisor a monthly fee based upon the average daily value of each Fund's net assets at the following annual rates: 0.55% of each Fund's average daily net assets not exceeding $500 million; 0.525% of average daily net assets in excess of $500 million but not exceeding $1 billion; and 0.50% of average daily net assets in excess of $1 billion. Intermediate Municipal Fund pays the Advisor a monthly fee at an annual rate of 0.55% of the average daily value of its net assets. The Advisor, with respect to BlackRock New Jersey Municipal Bond Fund, has voluntarily agreed to waive fees or expenses in order to limit expenses as a percentage of average daily net assets allocated to each class (excluding interest expense) as follows: 0.85% (for Service and Investor A Shares), 0.70% (for Investor A1 Shares), 1.60% (for Investor B and Investor C Shares), 1.10% (for Investor B1 Shares) and 1.20% (for Investor C1 Shares). The Advisor, with respect to BlackRock Pennsylvania Municipal Bond Fund, has voluntarily agreed to waive or reimburse fees or expenses in order to limit expenses as a percentage of average daily net assets allocated to each class (excluding interest expense) in order to limit expenses as follows: 0.85% (for Service and Investor A Shares), 0.70% (for Investor A1 Shares), 1.60% (for Investor B and Investor C Shares), 1.10% (for Investor B1 Shares) and 1.20% (for Investor C1 Shares). The Advisor, with respect to BlackRock Intermediate Municipal Fund, has contractually agreed to waive 0.05% of the average daily value of the Fund's net assets. 84 SEMI-ANNUAL REPORT NOVEMBER 30, 2008 Notes to Financial Statements (continued) For the six months ended November 30, 2008, the waivers, which are included in fees waived by advisor on the Statements of Operations, were as follows: - -------------------------------------------------------------------------------- Fees Waived by Advisor - -------------------------------------------------------------------------------- BlackRock New Jersey Municipal Bond Fund .......................... $62,562 BlackRock Pennsylvania Municipal Bond Fund ........................ $26,330 BlackRock Intermediate Municipal Fund ............................. $44,427 - -------------------------------------------------------------------------------- For BlackRock New Jersey Municipal Bond Fund and BlackRock Pennsylvania Municipal Bond Fund, the Advisor may reduce or discontinue these arrangements at any time without notice.

For the six months ended November 30, 2008, each Fund reimbursed the Advisor for certain accounting services, which are included in accounting services in the Statements of Operations. The reimbursements were as follows: - -------------------------------------------------------------------------------- Reimbursement to Advisor - -------------------------------------------------------------------------------- BlackRock California Insured Municipal Bond Fund .................. $2,845 BlackRock Florida Municipal Bond Fund ............................. $ 710 BlackRock New Jersey Municipal Bond Fund .......................... $2,292 BlackRock Pennsylvania Municipal Bond Fund ........................ $4,571 BlackRock Intermediate Municipal Fund ............................. $1,422 - -------------------------------------------------------------------------------- Effective October 1, 2008, each Fund has entered into a Distribution Agreement and Distribution Plans with BlackRock Investments, Inc. ("BII"), which replaced FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc. and its affiliates ("BDI") (collectively, the "Distributor") as sole distributor of the Funds. FAMD is a wholly owned subsidiary of Merrill Lynch Group, Inc. BII and BDI are affiliates of BlackRock, Inc. The service and distribution fees did not change as a result of this transaction. Pursuant to the Distribution Plans adopted by each Fund in accordance with Rule 12b-1 under the 1940 Act, each Fund pays the Distributor ongoing service and distribution fees.

Concentration Risk: Each Fund'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.

Subsequent Event: On January 1, 2009, BAC announced that it had completed its acquisition of Merrill Lynch, one of the largest stockholders of BlackRock, Inc. SEMI-ANNUAL REPORT NOVEMBER 30, 2008 95 Disclosure of Investment Advisory Agreement and Subadvisory Agreement The Board of Trustees of BlackRock California Insured Municipal Bond Fund of BlackRock California Municipal Series Trust (the "California Trust"), the Board of Trustees of BlackRock Florida Municipal Bond Fund, BlackRock New Jersey Municipal Bond Fund and BlackRock Pennsylvania Municipal Bond Fund of BlackRock Multi-State Municipal Series Trust (the "Multi-State Trust") and the Board of Trustees of BlackRock Intermediate Municipal Bond Fund of BlackRock Municipal Series Trust (the "Municipal Trust") (collectively, the "Board," the members of which are referred to as "Trustees") met in April and June 2008 to consider the approval of each of the California Trust's, Multi-State Trust's and Municipal Trust's investment advisory agreement (collectively, the "Advisory Agreement") with BlackRock Advisors, LLC (the "Advisor"), the fund's investment advisor. For simplicity, BlackRock California Insured Municipal Bond Fund, the California Trust, BlackRock Florida Municipal Bond Fund, BlackRock New Jersey Municipal Bond Fund, BlackRock Pennsylvania Municipal Bond Fund, the Multi-State Trust, BlackRock Intermediate Municipal Bond Fund and the Municipal Trust are referred to herein as the "Fund." The Board also considered the approval of each of the subadvisory agreements (collectively, the "Subadvisory Agreement") between the Advisor and BlackRock Investment Management, LLC (the "Subadvisor"). The Advisor and the Subadvisor are referred to herein as "BlackRock." The Advisory Agreement and the Subadvisory Agreement are referred to herein as the "Agreements." Activities and Composition of the Board The Board of the Fund consists of fifteen individuals, twelve of whom are not "interested persons" of the Fund as defined in the Investment Company Act of 1940, as amended (the "1940 Act") (the "Independent Trustees"). The Trustees are responsible for the oversight of the operations of the Fund and perform the various duties imposed on the directors of investment companies by the 1940 Act. The Independent Trustees have retained independent legal counsel to assist them in connection with their duties. The Chairman of the Board is an Independent Trustee. The Board established four standing committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee and a Performance Oversight Committee, each of which is composed of, and chaired by Independent Trustees. The Agreements Upon the consummation of the combination of BlackRock's investment management business with Merrill Lynch & Co., Inc.'s investment management business, including Merrill Lynch Investment Managers, L.P., and certain affiliates (the "Transaction"), the Fund entered into the Advisory Agreement with an initial two-year term and the Advisor entered into the Subadvisory Agreement with the Subadvisor with an initial two-year term. Consistent with the 1940 Act, prior to the expiration of the Agreements' respective initial two-year term, the Board is required to consider the continuation of the Fund's Agreements 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 the Fund by the personnel of BlackRock and its affiliates, including investment management, administrative services, shareholder services, oversight of fund accounting and custody, marketing services and assistance in meeting legal and regulatory requirements. The Board also received and assessed information regarding the services provided to the Fund by certain unaffiliated service providers. Throughout the year, the Board, acting directly and through its committees, considers at each of its meetings factors that are relevant to its annual consideration of the renewal of the Fund's Agreements, including the services and support provided to the Fund and its shareholders. Among the matters the Board considered were: (a) investment performance for one, three and five years, 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, if applicable, and other fees paid to BlackRock and its affiliates by the Fund, such as transfer agency fees and fees for marketing and distribution; (c) Fund operating expenses; (d) the resources devoted to and compliance reports relating to the Fund's investment objective, policies and restrictions; (e) the 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) periodic overview of BlackRock's business, including BlackRock's response to the increasing scale of its business. Board Considerations in Approving the Agreements The Approval Process: At an in-person meeting held on April 10, 2008, the Board reviewed materials relating to its consideration of the Agreements. At an in-person meeting held on June 5 - 6, 2008, the Fund's Board, including the Independent Trustees, unanimously approved the continuation of the Advisory Agreement between the Advisor and the Fund for a one-year term ending June 30, 2009 and the Subadvisory Agreement between the Advisor and BlackRock Investment Management, LLC for a one-year term ending June 30, 2009. In considering the approval of the Agreements, the Board received and discussed various materials provided to it in advance of the April 10, 2008 meeting. As a result of the discussions that occurred during the April 10, 2008 meeting, the Board requested and BlackRock provided additional information, as detailed below, in advance of the June 5 - 6, 2008 Board meeting. The Board considered all factors it believed relevant with respect to the Fund, including, among other factors: (a) the nature, extent and quality of the services provided by BlackRock; (b) the investment performance of the Fund and BlackRock portfolio management; (c) the advisory fee and the cost of the services and profits to be realized by BlackRock and certain affiliates from the relationship with the Fund; (d) economies of scale; and (e) other factors. 96 SEMI-ANNUAL REPORT NOVEMBER 30, 2008 Disclosure of Investment Advisory Agreement and Subadvisory Agreement (continued) Prior to the April 10, 2008 meeting, the Board requested and received materials specifically relating to the Agreements. The Board is engaged in an ongoing process with BlackRock to continuously review the nature and scope of the information provided to better assist its deliberations. These materials included (a) information independently compiled and prepared by Lipper, Inc. ("Lipper") on Fund fees and expenses, and the investment performance of the Fund as compared with a peer group of funds as determined by Lipper ("Peers"); (b) information on the profitability of the Agreements to BlackRock and certain affiliates, including their other relationships with the Fund, and a discussion of fall-out benefits; (c) a general analysis provided by BlackRock concerning investment advisory fees charged to other clients, such as institutional and closed-end funds, under similar investment mandates, as well as the performance of such other clients; (d) a report on economies of scale; (e) sales and redemption data regarding the Fund's shares; and (f) an internal comparison of management fees classified by Lipper, if applicable. At the April 10, 2008 meeting, the Board requested and subsequently received from BlackRock (i) a comprehensive analysis of total expenses on a fund-by-fund basis; (ii) further analysis of investment performance; (iii) further data regarding Fund profitability, Fund size and Fund fee levels; and (iv) additional information on sales and redemptions. The Board also considered other matters it deemed important to the approval process, 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 Fund. The Board did not identify any particular information as controlling, and each Trustee may have attributed different weights to the various items considered. A. Nature, Extent and Quality of the Services: The Board, including the Independent Trustees, reviewed the nature, extent and quality of services provided by BlackRock, including the investment advisory services and the resulting performance of the Fund. Throughout the year, the Board compared Fund performance to the performance of a comparable group of mutual funds as classified by Lipper and the performance of at least one relevant index or combination of indices. The Board met with BlackRock's senior management personnel responsible for investment operations, including the senior investment officers. The Board also reviewed the materials provided by the Fund's portfolio management team discussing Fund performance and the Fund's investment objective, strategies and outlook. The Board considered, among other factors, the number, education and experience of BlackRock's investment personnel generally and the Fund's portfolio management team, BlackRock's portfolio trading capabilities, BlackRock's use of technology, BlackRock's commitment to compliance and BlackRock's approach to training and retaining portfolio managers and other research, advisory and management personnel. The Board also reviewed BlackRock's compensation structure with respect to the Fund's portfolio management team and BlackRock's ability to attract and retain high-quality talent. In addition to advisory services, the Board considered the quality of the administrative and non-investment advisory services provided to the Fund. BlackRock and its affiliates provide the Fund with certain administrative, transfer agency, shareholder and other services (in addition to any such services provided to the Fund by third parties) and officers and other personnel as are necessary for the operations of the Fund. In addition to investment advisory services, BlackRock and its affiliates provide the Fund with other services, including (i) preparing disclosure documents, such as the prospectus, the statement of additional information and shareholder reports; (ii) assisting with daily accounting and pricing; (iii) overseeing and coordinating the activities of other service providers; (iv) organizing Board meetings and preparing the materials for such Board meetings; (v) providing legal and compliance support; and (vi) performing other administrative functions necessary for the operation of the Fund, such as tax reporting and fulfilling regulatory filing requirements. The Board reviewed the structure and duties of BlackRock's fund administration, accounting, legal and compliance departments. B. The Investment Performance of the Fund and BlackRock: The Board, including the Independent Trustees, also reviewed and considered the performance history of the Fund. In preparation for the April 10, 2008 meeting, the Board was provided with reports, independently prepared by Lipper, which included a comprehensive analysis of the Fund's performance. The Board also reviewed a narrative and statistical analysis of the Lipper data that was prepared by BlackRock, which analyzed various factors that affect Lipper's rankings. In connection with its review, the Board received and reviewed information regarding the investment performance of the Fund as compared to a representative group of similar funds as determined by Lipper and to all funds in the Fund's applicable Lipper category. The Board was provided with a description of the methodology used by Lipper to select peer funds. The Board regularly reviews the performance of the Fund throughout the year. The Board attaches more importance to performance over relatively long periods of time, typically three to five years. SEMI-ANNUAL REPORT NOVEMBER 30, 2008 97 Disclosure of Investment Advisory Agreement and Subadvisory Agreement (continued) The California Insured Municipal Bond Fund ranked in the second quartile on a net basis against its Lipper peer universe for each of the one-, three- and five-year periods ended December 31, 2007, respectively. The BlackRock Florida Municipal Bond Fund ranked in the third, second and second quartiles on a net basis against its Lipper peer universe for the one-, three- and five-year periods ended December 31, 2007, respectively. The Board noted that the BlackRock Florida Municipal Bond Fund's investment performance for the one year period was disappointing, but that longer-term performance meets the Board's expectations. The Board typically gives greater weight to longer-term results. The BlackRock New Jersey Municipal Bond Fund ranked in the fourth, first and first quartiles on a net basis against its Lipper peer universe for the one-, three- and five-year periods ended December 31, 2007, respectively. The Board noted that the BlackRock New Jersey Municipal Bond Fund's investment performance for the one-year period was disappointing, but that longer-term performance meets the Board's expectations. The Board typically gives greater weight to longer-term results. The BlackRock Pennsylvania Municipal Bond Fund ranked in the second quartile on a net basis against its Lipper peer universe for each of the one-, three- and five-year periods ended December 31, 2007, respectively. The BlackRock Intermediate Municipal Bond Fund ranked in the third quartile on a net basis against its Lipper peer universe for each of the one-, three- and five-year periods ended December 31, 2007, respectively. The Board expressed its concern with the BlackRock Intermediate Municipal Bond Fund's third quartile performance. The Board noted that for each of the periods, the BlackRock Intermediate Municipal Bond Fund's third quartile performance was near its Lipper median. The Board considered BlackRock's planned changes in its fixed-income organization. C. Consideration of the Advisory Fees and the Cost of the Services and Profits to be Realized by BlackRock and its Affiliates from the Relationship with the Fund: The Board, including the Independent Trustees, reviewed the Fund's contractual advisory fee rates compared with the other funds in its Lipper category. It also compared the Fund's total expenses to those of other comparable funds. The Board considered the services provided and the fees charged by BlackRock to other types of clients with similar investment mandates, including separately managed institutional accounts. The Board received and reviewed statements relating to BlackRock's financial condition and profitability with respect to the services it provided to the Fund. The Board was also provided with a profitability analysis that detailed the revenues earned and the expenses incurred by BlackRock and certain affiliates that provide services to the Fund. The Board reviewed BlackRock's profitability with respect to the Fund and each fund the Board currently oversees for the year ended December 31, 2007 compared to aggregated profitability data provided for the year ended December 31, 2005. In addition, the Board considered the cost of the services provided to the Fund by BlackRock, and BlackRock's and its affiliates' profits relating to the management and distribution of the Fund and the other funds advised by BlackRock and its affiliates. As part of its analysis, the Board reviewed BlackRock's methodology in allocating its costs to the management of the Fund and concluded that there was a reasonable basis for the allocation. The Board also considered whether BlackRock has the financial resources necessary to attract and retain high-quality investment management personnel to perform its obligations under the Agreements and to continue to provide the high quality of services that are expected by the Board. The Board took into account that that the BlackRock California Insured Municipal Bond Fund, BlackRock Florida Municipal Bond Fund, BlackRock New Jersey Municipal Bond Fund and BlackRock Pennsylvania Municipal Bond Fund has an advisory fee arrangement that includes breakpoints that adjust the fee rate downward as the size of each Fund increases, thereby allowing shareholders the potential to participate in economies of scale. The Board recognized that BlackRock Florida Municipal Bond Fund has contractual advisory fees higher than its Peers. The Board noted that BlackRock has agreed to voluntarily cap the total annual operating expenses, excluding certain expenses, of one or more share classes of each of BlackRock New Jersey Municipal Bond Fund and BlackRock Pennsylvania Municipal Bond Fund, at certain levels. The Board observed that those expense caps benefited shareholders by limiting total fees. The Board took into account that BlackRock has contractually agreed to waive a portion of its advisory fee for the BlackRock Intermediate Municipal Bond Fund, thereby lowering Fund expenses. D. Economies of Scale: The Board, including the Independent Trustees, considered the extent to which economies of scale might be realized as the assets of the Fund increase and whether there should be changes in the advisory fee rate or structure in order to enable the Fund to participate in these economies of scale. The Board, including the Independent Trustees, considered whether the shareholders would benefit from economies of scale and whether there was potential for future realization of economies with respect to the Fund. The Board considered that the funds in the BlackRock fund complex share common resources and, as a result, an increase in the overall size of the complex could permit each fund to incur lower expenses than it would otherwise as stand-alone entities. The Board also considered the anticipated efficiencies in the processes of BlackRock's overall operations as it continues to add personnel and commit capital to expand the scale of operations. The Board found, based on its review of comparable funds, that the Fund's management fee is appropriate in light of the scale of the Fund. 98 SEMI-ANNUAL REPORT NOVEMBER 30, 2008 Disclosure of Investment Advisory Agreement and Subadvisory Agreement (concluded) E. Other Factors: The Board also took into account other ancillary or "fall-out" benefits that BlackRock may derive from its relationship with the Fund, both tangible and intangible, such as BlackRock's ability to leverage its investment professionals that manage other portfolios, an increase in BlackRock's profile in the investment advisory community, and the engagement of BlackRock's affiliates as service providers to the Fund, including for administrative, transfer agency and distribution services. The Board also noted that BlackRock may use third-party research obtained by soft dollars generated by certain mutual fund transactions to assist itself in managing all or a number of its other client accounts. In connection with its consideration of the Agreements, the Board also received information regarding BlackRock's brokerage and trade execution practices throughout the year. Conclusion The Board approved the continuation of the Advisory Agreement between the Advisor and the Fund for a one-year term ending June 30, 2009 and the Subadvisory Agreement between the Advisor and BlackRock Investment Management, LLC for a one-year term ending June 30, 2009. Based upon its evaluation of all these factors in their totality, the Board, including the Independent Trustees, was satisfied that the terms of the Agreements were fair and reasonable and in the best interest of the Fund and the Fund's shareholders. In arriving at a decision to approve the Agreements, the Board did not identify any single factor or group of factors as all-important or controlling, but considered all factors together. The Independent Trustees were also assisted by the advice of independent legal counsel in making this determination. The contractual fee arrangements for the Fund reflect the result of several years of review by the Trustees and predecessor Trustees, and discussions between the Trustees (and predecessor Trustees) and BlackRock. Certain aspects of the arrangements may be the subject of more attention in some years than in others, and the Trustees' conclusions may be based in part on their consideration of these arrangements in prior years.
