While this has been an issue for much of 2007, recent headlines and some high-profile credit collapses reignited concerns that credit problems could spill over into the broader economy and derail global financial markets. Although volatility has reared its head throughout the year, the fundamental market and economic backdrop has been little changed. U.S. economic activity has decelerated, led by a slowdown in the housing market, but economies outside the United States remain robust, which has been a boon for U.S. exports. Through July, the Federal Reserve Board had kept the target short-term interest rate on hold at 5.25%. For the most part, equities continued to find support in robust merger-and-acquisition activity, a healthy global economy, tame inflation, relatively low interest rates, still-positive earnings growth and attractive valuations. These tailwinds generally prevailed over such headwinds as the weakening U.S. economy, slowing housing market, escalating geopolitical concerns and high energy prices, leading the Standard & Poor's (S&P) 500 Index and the Dow Jones Industrial Average to post new record highs in mid-July before succumbing to the latest market correction. Meanwhile, mixed economic signals and the credit market debacle have made for a volatile backdrop for fixed income, with investors fleeing from bonds associated with the housing and credit markets in favor of higher-quality Treasury bonds. As a result, the 10-year Treasury yield, which touched 5.30% in June (its highest level in five years), fell to nearly 4.75% by period-end. Prices correspondingly rose, reflecting the investor flight to quality. Against this backdrop, financial markets posted mixed results for the six-month period ended July 31, 2007, but continued to exhibit relative strength when measured over the past year: Total Returns as of July 31, 2007 6-month 12-month ============================================================================================================== U.S. equities (S&P 500 Index) +2.10% +16.13% - -------------------------------------------------------------------------------------------------------------- Small cap U.S. equities (Russell 2000 Index) -2.47 +12.12 - -------------------------------------------------------------------------------------------------------------- International equities (MSCI Europe, Australasia, Far East Index) +8.38 +23.91 - -------------------------------------------------------------------------------------------------------------- Fixed income (Lehman Brothers U.S. Aggregate Bond Index) +1.86 + 5.58 - -------------------------------------------------------------------------------------------------------------- Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) +1.17 + 4.27 - -------------------------------------------------------------------------------------------------------------- High yield bonds (Lehman Brothers U.S. Corporate High Yield 2% Issuer Cap Index) -1.75 + 6.44 - -------------------------------------------------------------------------------------------------------------- Past performance is no guarantee of future results.

Doll, Jr. Fund President and Trustee THIS PAGE NOT PART OF YOUR FUND REPORT ANNUAL REPORTS JULY 31, 2007 3 A Discussion With Your Funds' Portfolio Managers The Funds provided competitive returns relative to their respective Lipper category averages for the fiscal year, as we remained focused on protecting net asset value and enhancing yield in the portfolios. Discuss the recent market environment relative to municipal bonds. Long-term bond yields ended the 12-month period slightly lower (and prices modestly higher), but exhibited considerable volatility along the way. As the 12-month period began, bond prices were improving (and yields falling) amid a backdrop of weakening U.S. economic growth. The bond price improvement accelerated in response to the Federal Reserve Board's (the Fed) decision on August 8, 2006 to keep its target interest rate on hold at 5.25% after 17 consecutive interest rate hikes since mid-2004. The rally continued in the fall amid moderating oil prices and slower gross domestic product (GDP) growth. By the end of November 2006, 30-year U.S. Treasury bond yields had fallen to 4.56%, a decline of 51 basis points (.51%) from July 31. In early 2007, bond yields began to rise (and prices fall) due to strong competition from improving U.S. equity markets, continued moderate employment growth, higher bond yields overseas and growing investor conviction that the Fed would keep rates steady for the remainder of 2007. By the end of May, the 30-year Treasury yield was back up to 5.06%, but fell to 4.92% by the end of July amid renewed fears that ongoing problems in the subprime mortgage sector could spill over to other financial markets. This resulted in a significant "flight-to-quality" rally in the bond market and in the U.S. Treasury market in particular. Year-over-year, the yield on the 30-year Treasury bond fell 15 basis points, while 10-year Treasury note yields declined 21 basis points to 4.78%. Movements in tax-exempt bond yields generally mimicked those seen in the taxable market. As measured by Municipal Market Data, yields on 30-year, Aaa-rated municipal bonds declined 10 basis points over the past year to 4.37%, while 10-year, AAA-rated issues saw their yields inch down 2 basis points to 3.97%. Investor demand for municipal product remained strong throughout the past 12 months. Statistics from the Investment Company Institute indicate that tax-exempt mutual funds received over $14.2 billion in net new cash flows in the first six months of 2007, an increase of more than 118% compared to the same period in 2006. Demand softened somewhat in June and July as the increase in bond yields made individual municipal bond purchases attractive compared to the relatively stable yields generated by tax-exempt mutual funds. Weekly fund flows for long-term municipal bond funds, as measured by AMG Data, averaged $224 million during these months, down from a weekly average of $415 million in April of this year. Still, 2007's average weekly flows remain almost twice those seen a year ago. In the past three months, investors received approximately $100 billion from bond maturities, coupon income and the proceeds from various early redemptions. These monies helped support the strong demand for tax-exempt products in recent months. Municipal bond volume appears to be on pace to set a new annual issuance record. During the three months ended July 2007, municipalities issued over $125 billion in new tax-exempt securities, an increase of 16.7% relative to levels a year earlier. Over the past six months, issuance has exceeded $232 billion, a 23% increase versus year-ago levels. Over the past year, more than $439 billion in new tax-exempt bonds was marketed, an increase of 19% compared to a year ago. Thus far in 2007, issuance is running more than 6% ahead of 2005's record pace. Underwritings exceeding $1 billion in size continued to dominate the new-issue calendar, although the recent market volatility has resulted in the postponement of a number of additional deals of this magnitude. Nevertheless, these deals continued to meet with positive demand from various investor classes, making their placement relatively easy with minimal, if any, market disruption. The market's technical position appears reasonably balanced, as heavy new issuance has been met with continued strong demand. We expect that both traditional and non-traditional investors will continue to be drawn to the municipal market given relatively stable tax-exempt yield ratios and the steepness of the municipal curve compared to the taxable curve. It is likely that the recent rise in bond yields will put some pressure on refunding issuance, which is up 58% so far this year. Any decline in the recent pace of issuance can only be supportive of the municipal market's performance in the coming months. 4 ANNUAL REPORTS JULY 31, 2007 BlackRock Florida Municipal Bond Fund Describe conditions in the State of Florida. The State of Florida ended the period with ratings of Aa1, AAA and AA+ as assigned by Moody's, Standard & Poor's and Fitch, respectively, all with stable trends. Florida's net tax-supported debt ranks 20th in the nation on a per-capita basis and 19th as a percentage of personal income, according to Moody's. The state's 2006 per-capita personal income of $35,798 was 20th in the nation, according to the U.S. Department of Commerce, and approximated the national average of $36,276. Florida's July 2007 unemployment rate was 3.9%, which compared favorably to the U.S. rate of 4.6%. Led by continuing weakness in the housing market, Florida's fiscal year 2006 - 2007 revenues missed projections and the state now expects to report an operating deficit of $400 million for the year. As a result, appropriations for fiscal year 2007 - 2008 were immediately reduced by an additional 4% as new revenue forecasts are finalized. Property-tax reform remains a key credit factor for local governments in Florida, as most will be required to make significant budget adjustments going forward. How did the Fund perform during the fiscal year? For the 12-month period ended July 31, 2007, BlackRock Florida Municipal Bond Fund's Institutional, Investor A, Investor A1, Investor B, Investor C and Investor C1 Shares had total returns of +3.88%, +3.53%, +3.78%, +3.36%, +2.74% and +3.26%, respectively. (Fund results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information can be found on pages 10 - 18 of this report to shareholders.) For the same period, the Lehman Brothers Municipal Bond Index returned +4.27% and the Lipper Florida Municipal Debt Funds category posted an average return of +3.44%. The Lehman Index measures the performance of municipal bonds in all 50 states, whereas the Lipper category tracks funds that limit their investment to those securities exempt from taxation in the State of Florida. The Fund provided strong relative returns and a competitive yield relative to its Lipper category average during the 12-month period. Performance was driven by our focus on the long end of the yield curve, which outperformed as the curve flattened in the first half of the year. Our exposure to non-investment-grade and lower-rated issues also contributed to performance in the first six months as credit spreads (versus higher-quality municipal issues of comparable maturity) tightened. Both of these dynamics shifted in the latter half of the period as the curve resteepened somewhat and turmoil in the credit markets caused spreads to widen. During this time, our exposure to A-rated hospital issues contributed to performance, as did our relatively neutral posture on interest rate risk. Our neutral duration meant that the Fund held more steady than competitor funds that had assumed a short or long bias in what was a volatile period for interest rates. What changes were made to the portfolio during the period? We continued our efforts to increase the level of income provided to shareholders while muting the Fund's net asset value volatility. To that end, we generally targeted premium-coupon bonds in the 20-year to 30-year maturity range whenever they became available. We continued to find the most attractive risk/reward trade-off here, although opportunities were somewhat limited as new municipal issuance in the State of Florida increased less than 3% over the 12 months and few of the new issues met our desired investment characteristics. Much of the supply came in the form of refinancings and/or with coupons below 5%. We wanted to avoid giving up bonds booked in the portfolio at higher yields relative to those available in the current low interest rate environment. Having said that, market volatility in the second half of the year did present some opportunities for the portfolio. In the March - April timeframe, we added some uninsured hospital bonds to the portfolio as spreads widened and we were able to purchase these at relatively attractive prices. We also were able to obtain secondary insurance for one of these bonds, which serves to enhance its value in the marketplace. In May and June, we saw long-term yields reach levels not seen since July 2006. The rise in yields (and fall in prices) allowed us to sell some prerefunded bonds in the four-year to six-year maturity range and purchase bonds in the 20-year to 30-year part of the yield curve. This also presented an opportunity to extend from a neutral to slightly long portfolio duration, reflecting a modestly constructive view of the market. How would you characterize the Fund's position at the close of the period? The Fund ended the period fully invested and with a neutral to slightly long duration, reflecting a shift we made after rates rose dramatically in the second quarter of 2007. With rates at historic lows for some time, we were finding limited opportunities to enhance the portfolio's structure. However, ANNUAL REPORTS JULY 31, 2007 5 A Discussion With Your Funds' Portfolio Managers (continued) heightened volatility toward period-end translated into increased opportunities. Still, our mainline strategy is unchanged: We generally remain focused on longer-dated Florida issues, which we believe offer greater potential for yield enhancement as the curve resteepens. We will continue to exercise patience as we look for 20-year to 30-year bonds with coupons in the area of 5%. Robert D. Sneeden Portfolio Manager BlackRock Florida Municipal Bond Fund BlackRock New Jersey Municipal Bond Fund Describe conditions in the State of New Jersey. The State of New Jersey is rated Aa3, AA and AA- by Moody's, Standard & Poor's and Fitch, respectively, all with stable outlooks. New Jersey ranks fourth in both debt per capita and debt as a percent of personal income, according to Moody's. It ranked second in per-capita personal income in 2006 (preliminary), according to the U.S. Department of Commerce. New Jersey's July 2007 unemployment rate was 4.6%, consistent with the national rate. Late in June, New Jersey lawmakers approved a $33.5 billion fiscal year 2008 budget that increases spending by $2.7 billion, mainly for property-tax relief. The $2.7 billion increase is primarily financed by roughly $1.4 billion in reserves and deferrals available at fiscal year-end 2007 and $1.1 billion of projected revenue growth in fiscal year 2008. Continuing credit issues include budgetary pressures from retiree health care costs and pensions, especially as the amounts and uses of past pension contributions are now in question. How did the Fund perform during the fiscal year? For the 12-month period ended July 31, 2007, BlackRock New Jersey Municipal Bond Fund's Institutional, Service, Investor A, Investor A1, Investor B, Investor B1, Investor C and Investor C1 Shares had total returns of +3.80%, +3.55%, +3.55%, +3.60%, +2.77%, +3.19%, +2.68% and +3.18%, respectively. (Fund results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information can be found on pages 10 - 18 of this report to shareholders.) For the same period, the Lehman Brothers Municipal Bond Index returned +4.27% and the Fund's comparable Lipper category of New Jersey Municipal Debt Funds posted an average return of +3.68%. Unlike the Lehman Index, which measures the performance of municipal bonds nationally, the Lipper category consists of funds that limit their investment to securities exempt from taxation in the State of New Jersey. Rapidly changing market conditions made for fairly erratic performance during the annual period. The second half, in particular, was marked by ongoing turmoil in the subprime lending business, which triggered significant volatility in fixed income assets overall; municipals were no exception. Despite the difficult backdrop, the Fund generally tracked the performance of its Lipper category average. In the first six months, increased exposure to longer-duration municipal bonds contributed positively to both total return and distributable income, as these issues generally outperformed their shorter-maturity peers during the period and their characteristically higher yields allowed us to maintain the Fund's slightly above-average distribution rate. The Fund's investments in higher yielding municipal securities also aided returns during this period as contracting credit spreads made for a favorable environment. The Fund's high yield exposure and comparatively longer-maturity profile proved disadvantageous in the second half of the fiscal year, largely due to a widening in credit spreads and a significant pick-up in market volatility, especially in the fourth fiscal quarter (May - July). The ensuing rise in interest rates led to the underperformance of certain sector holdings of the Fund, namely housing and hospitals, which also negatively impacted the portfolio's total return. Further challenging performance throughout the period was the calling away of some of the Fund's higher-coupon bonds. In an environment where we cannot replace those higher yields, this occurrence dampened the distribution of the Fund. What changes were made to the portfolio during the period? Portfolio activity reflected our efforts to improve distributable income for shareholders and to increase the Fund's capital appreciation potential. A dearth of new issuance, coupled with the low absolute yields available, prompted us to largely retain the Fund's seasoned holdings, which consist of premium coupons with high credit quality and attractive book yields. For the annual period, new issuance of New Jersey municipal bonds was down 1% versus the prior fiscal year. This figure somewhat overstates the actual supply available to the Fund, however, as it takes into account the state's refunding of $3.6 billion in bonds issued as part of the tobacco industry settlement (in January). Excluding the tobacco settlement bonds, new issuance was down a more considerable 31%. 6 ANNUAL REPORTS JULY 31, 2007 Still, we came across several opportunities to add new names and to enhance credit structures within the portfolio. Our participation in the abovementioned tobacco transaction provided a gain for the Fund via the price appreciation associated with the prerefunding of existing holdings, and allowed us to maintain our exposure to this sector. Other purchases during the annual period consisted primarily of new-issue housing bonds, new-issue uninsured hospital bonds and out-of-favor coupons (particularly discounted bonds), each of which offers above-market yield and enhances the portfolio's liquidity and potential for capital appreciation. We also added a few zero-coupon bonds, including Puerto Rico zeros. In addition to housing and hospitals, we found attractive credits in higher education (colleges and universities), and this remains a sector of interest. In contrast, we continued to trim the portfolio's short-term holdings, in particular shorter-dated pre-refunded bonds and high-coupon, short-call bonds. The rationale is that these bonds are priced with a premium, but as they come close to their call date, their value depreciates at an accelerating pace. (Generally, we prefer to sell once the bonds are within a three-year window to their call date.) While this move temporarily hurts the Fund's distributable income, we believe it is a worthwhile trade-off to protect the portfolio's future total return potential. In redeploying the proceeds of these sales and initiating new purchases, we focused primarily on the long end of the municipal yield curve via the abovementioned credits. How would you characterize the Fund's position at the close of the period? We maintained a fully invested portfolio throughout and ended the annual period with a slightly longer duration than that of our comparable Lipper peer group. Going forward, we intend to maintain our focus on enhancing the Fund's yield and capital appreciation potential, while taking advantage of above-average interest rate volatility to execute relative value trades within both the institutional and retail sectors. We continue to believe that individual security selection and yield will be the key drivers of the Fund's future performance. Accordingly, we expect to prudently add duration and exposure to the long end of the municipal yield curve (in favor of higher yields and greater opportunity to generate incremental income for the portfolio), while being mindful of the increased volatility that has entered the market. Timothy T. Browse, CFA Portfolio Manager BlackRock New Jersey Municipal Bond Fund ANNUAL REPORTS JULY 31, 2007 7 A Discussion With Your Funds' Portfolio Managers (concluded) BlackRock Pennsylvania Municipal Bond Fund Describe conditions in the Commonwealth of Pennsylvania. At period-end, the Commonwealth of Pennsylvania was rated Aa2, AA and AA by Moody's, Standard & Poor's and Fitch, respectively, all with stable trends. Pennsylvania ranks 24th in both debt per capita and debt as a percent of personal income, according to Moody's. Pennsylvania's per-capita income of $36,680 ranked 18th in the nation, according to the U.S. Department of Commerce. Pennsylvania's July 2007 unemployment rate was 4.3%, compared to the U.S. rate of 4.6%. State employment numbers continue to post incremental gains in contrast to a declining labor force. Pennsylvania's fiscal year 2007 revenue collections reportedly exceeded official estimates by $650 million, primarily thanks to strong corporate and personal income-tax receipts. Negotiations surrounding the 2007 - 2008 budget were punctuated by a politically dramatic one-day furlough of 24,000 non-essential state workers. The $27.3 billion budget would be 3.5% larger than the prior year's budget, which is below the 5% - 6% growth rate seen in recent years. Expanded property-tax rebates initially will be financed by the Commonwealth's lottery surplus; however, legalized slot gambling revenues have begun to flow into Pennsylvania's coffers, with year-to-date gaming revenues of $427 million. Casino openings will accelerate over the next couple of years with the development and construction of newly licensed casino operator projects. Homeowners in Pennsylvania are expected to see reductions in their school property-tax bills estimated at a rough average of $200 per household. Pennsylvania law now requires most school districts to ask voters this year whether they want to see property taxes cut further by increasing local income taxes, and also requires school boards to obtain voter approval for tax increases in excess of inflation. This could present challenges for local budgeting. How did the Fund perform during the fiscal year? For the 12-month period ended July 31, 2007, BlackRock Pennsylvania Municipal Bond Fund's Institutional, Service, Investor A, Investor A1, Investor B, Investor B1, Investor C and Investor C1 Shares had total returns of +4.01%, +3.75%, +3.76%, +3.81%, +3.06%, +3.49%, +3.07% and +3.29%, respectively. (Fund results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information can be found on pages 10 - 18 of this report to shareholders.) For the same period, the benchmark Lehman Brothers Municipal Bond Index, which measures the performance of municipal bonds nationwide, returned +4.27%. Fund returns were competitive with the +3.57% average return of the Lipper Pennsylvania Municipal Debt Funds category for the 12-month period. The Lipper category consists of funds that limit their investment to those securities exempt from taxation in Pennsylvania. Fund performance continued to benefit from our focus on the long end of the yield curve, which outperformed the shorter end as the curve flattened, as well as from the portfolio's advantageous income component compared to its peers. In fact, the Fund increased its average coupon to above the industry average as a result of its merger with the former BlackRock Pennsylvania Municipal Bond Portfolio in October. Also additive to performance were our positions in lower-rated issues, which registered strong price performance as credit spreads in the municipal bond market continued to contract in the first six months. Bond calls detracted from performance during the year, as we were not able to replace our higher-yielding credits with similar coupons in the prevailing low-interest-rate environment. What changes were made to the portfolio during the period? We did not significantly alter the portfolio's composition or adjust our underlying strategy during the fiscal year. For the most part, we maintained our focus on protecting the Fund's net asset value and providing shareholders with above-average income. We continued to emphasize longer-dated bonds, typically in the 25-year to 30-year maturity range, as the yield curve flattened. Given the historically low yields in the municipal market, and lack of attractive new issuance, we found little incentive to restructure the portfolio. 8 ANNUAL REPORTS JULY 31, 2007 Having said that, we did take steps to increase the port-folio's duration, which had fallen below the Lipper peer group average when the Fund absorbed the former BlackRock Pennsylvania Municipal Portfolio in October. This involved purchasing securities with longer maturities and selling those with shorter maturities. In doing so, we participated in some "tax-swap" transactions, whereby we were willing to take losses on the sale of select bonds in order to offset present and future capital gains, which are taxable to our shareholders. This also meant that we were swapping into bonds with higher yields, thereby allowing us to establish a new book yield for the portfolio. Issuance of new municipal bonds in Pennsylvania municipalities increased 22% over the 12-month period, although most of the new bonds came with shorter maturities and lower yields than we were targeting. We maintained ample exposure to bonds issued by the Commonwealth of Puerto Rico, which are tax-exempt in all 50 states. In our view, the case for continued investment in Puerto Rico bonds remains strong. How would you characterize the Fund's position at the close of the period? We ended the period with a fully invested portfolio and a slightly long duration relative to our peers, the result of our efforts to extend duration since last fall. Municipal yields and credit spreads remain near their all-time lows and the slope of the yield curve is historically very flat. As such, we believe longer-dated securities offer the best relative value at this time. We continue to look for maturities in the 25-year area and to favor a neutral to slightly long portfolio duration, which offers the benefit of incremental yield. Ultimately, we believe that above-average yields can provide for competitive Fund returns over time. This reflects our core strategy of seeking to enhance yield for shareholders while also protecting the Fund's underlying value. William R.

The following example (which is based on a hypothetical investment of $1,000 invested on February 1, 2007 and held through July 31, 2007) is 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 first table below provides 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 in the first line under the heading entitled "Expenses Paid During the Period." The second table below provides 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 table 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 second table is 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.

Significant Accounting Policies: On September 29, 2006, Merrill Lynch Multi-State Municipal Series Trust (consisting of Merrill Lynch Florida Municipal Bond Fund, Merrill Lynch New Jersey Municipal Bond Fund and Merrill Lynch Pennsylvania Municipal Bond Fund) was renamed BlackRock Multi-State Municipal Series Trust (the "Trust"), consisting of BlackRock Florida Municipal Bond Fund, BlackRock New Jersey Municipal Bond Fund and BlackRock Pennsylvania Municipal Bond Fund (the "Funds" or individually as the "Fund"), respectively. The Funds are registered under the Investment Company Act of 1940, as amended, as non-diversified, open-end management investment companies. The Funds' financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. Each Fund offers multiple classes of shares. Effective October 2, 2006, BlackRock Florida Municipal Bond Fund's Class A, Class B, Class C and Class I Shares were redesignated Investor A1, Investor B, Investor C1 and Institutional Shares, respectively. BlackRock New Jersey Municipal Bond Fund's and BlackRock Pennsylvania Municipal Bond Fund's Class A, Class B, Class C and Class I Shares were redesignated Investor A1, Investor B1, Investor C1 and Institutional Shares, respectively. Also effective October 2, 2006, BlackRock Florida Municipal Bond Fund's Investor A and Investor C Shares commenced operations. BlackRock New Jersey Municipal Bond Fund's and BlackRock Pennsylvania Municipal Bond Fund's Service, Investor A, Investor B and Investor C Shares commenced operations. Institutional and Service Shares are sold only to certain eligible investors. Investor A and Investor A1 Shares are sold with a front-end sales charge. 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 certain changes to the Investor A distribution plan). Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Funds. (a) Valuation of investments -- Municipal bonds are traded primarily in the over-the-counter ("OTC") markets and are valued at the last available bid price in the OTC market or on the basis of values as obtained by a pricing service. Pricing services use valuation matrixes that incorporate both dealer-supplied valuations and valuation models. The procedures of the pricing service and its valuations are reviewed by the officers of the Funds under the general direction of the Board of Trustees. Such valuations and procedures are reviewed periodically by the Board of Trustees of the Trust. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their closing prices as of the close of such exchanges. Options written or purchased are valued at the last sale price in the case of exchange-traded options. Options traded in the OTC market are valued at the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued by quoted fair values received daily by the Funds' pricing service. Investments in open-end investment companies are valued at their net asset value each business day. Securities and other assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Trustees of the Trust. (b) Derivative financial instruments -- Each Fund may engage in various portfolio investment strategies both to increase their returns and to hedge, or protect, their exposure to interest rate movements and movements in the securities markets. Losses may arise due to changes in the value of the contract due to an unfavorable change in the price of the underlying security or index, or if the counterparty does not perform under the contract. The counterparty for certain instruments may pledge cash or securities as collateral. o Financial futures contracts -- Each Fund may purchase or sell financial futures contracts and options on such financial futures contracts. Financial futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Fund deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the 56 ANNUAL REPORTS JULY 31, 2007 Notes to Financial Statements (continued) contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. o Forward interest rate swaps -- Each Fund may enter into forward interest rate swaps. In a forward interest rate swap, the Fund and the counterparty agree to pay or receive interest on a specified notional contract amount, commencing on a specified future effective date, unless terminated earlier. When the agreement is closed, the Fund records a realized gain or loss in an amount equal to the value of the agreement. o Swaps -- Each Fund may enter into swap agreements, which are OTC contracts in which the Fund and a counterparty agree to make periodic net payments on a specified notional amount. The net payments can be made for a set period of time or may be triggered by a pre-determined credit event. The net periodic payments may be based on a fixed or variable interest rate; the change in market value of a specified security, basket of securities, or index; or the return generated by a security. These periodic payments received or made by the Fund are recorded in the accompanying Statement 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. (c) Municipal bonds held in trust -- Each Fund invests in leveraged residual certificates ("TOB Residuals") issued by tender option bond trusts ("TOBs"). A TOB is established by a third party sponsor forming a special purpose entity, into which a Fund, or an agent on behalf of the Fund, transfers municipal 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, which are generally issued to the Fund which made the transfer or to affiliates of the Fund. Each Fund's transfers of the municipal securities to a TOB do not qualify for sale treatment under Statement of Financial Accounting Standards No. 140 "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities," therefore the municipal securities deposited into a TOB are presented in the Funds' schedules of investments and the proceeds from the transactions are reported as a liability for trust certificates of the Funds. Similarly, proceeds from residual certificates issued to affiliates, if any, from the transaction are included in the 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 a Fund. 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. The residual interests held by the Funds include the right of the Funds (1) to cause the holders of a proportional share of floating rate certificates to tender their certificates at par, and (2) to transfer a corresponding share of the municipal securities from the TOB to the Funds. At July 31, 2007, the aggregate value of the underlying municipal securities transferred to TOBs and the related liability for trust certificates were: - -------------------------------------------------------------------------------- Range of Interest Underlying Liability Rates on the Municipal for Liability of Bonds Trust Trust Transferred Certificates Certificates to TOB's - -------------------------------------------------------------------------------- BlackRock Florida Municipal Bond Fund ................... $10,437,500 3.675% - 3.74% $22,331,350 BlackRock New Jersey Municipal Bond Fund ................... $20,418,050 3.652% - 3.686% $31,750,416 BlackRock Pennsylvania Municipal Bond Fund ................... $58,410,000 3.652% - 3.701% $91,376,117 - -------------------------------------------------------------------------------- Financial transactions executed through TOBs generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment, but tend to outperform the market for fixed rate bonds when interest rates decline or remain relatively stable. Should short-term interest rates rise, the Funds' investments in TOB Residuals likely will adversely affect the Funds' investment income -- net and distributions to shareholders. Fluctuations in the market value of municipal securities deposited into the TOB may adversely affect the Funds' net asset value per share. While the Fund's investment policies and restrictions expressly permit investments in inverse floating rate securities such as ANNUAL REPORTS JULY 31, 2007 57 Notes to Financial Statements (continued) TOB Residuals, they generally do not allow the Funds to borrow money for purposes of making investments. The Funds' management believes that the Funds' restrictions on borrowings do not apply to the secured borrowings deemed to have occurred for accounting purposes. (d) Income taxes -- It is each Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. (e) Security transactions and investment income -- Security 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 basis. The Funds amortize all premiums and discounts on debt securities. (f) Prepaid registration fees -- Prepaid registration fees are charged to expense as the related shares are issued. (g) 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. (h) Expenses -- Certain expenses have been allocated to the individual funds in the Trust on a pro rata basis based upon the respective aggregate net asset value of each fund included in the Trust. (i) Bank overdraft -- BlackRock Florida Municipal Bond Fund recorded a bank overdraft which resulted from management estimates of available cash. (j) Recent accounting pronouncements -- In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109." 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 mutual funds, before being measured and recognized in the financial statements. Adoption of FIN 48 is required for the last net asset value calculation in the first required financial statement reporting period for fiscal years beginning after December 15, 2006. The impact on each of the Funds' financial statements, if any, is currently being assessed. 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. Management is currently evaluating the implication of FAS 157. At this time, its impact on the Funds' financial statements has not been determined. 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. At this time, management is evaluating the implications of FAS 159 and its impact on the Fund's financial statements, if any, has not been determined. (k) Reclassification -- BlackRock New Jersey Municipal Bond Fund U.S. generally accepted accounting principles require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. Accordingly, during the current year, $480,404 has been reclassified between paid-in capital in excess of par and accumulated net realized capital losses as a result of a permanent difference attributable to the expiration of capital loss carryovers. This reclassification has no effect on net assets or net asset values per share. 2. Investment Advisory Agreement and Transactions with Affiliates: On September 29, 2006, BlackRock, Inc. and Merrill Lynch & Co., Inc. ("Merrill Lynch") combined Merrill Lynch's investment management business, Merrill Lynch Investment Managers, L.P. ("MLIM"), and its affiliates, including Fund Asset Management, L.P.

The general partner of FAM is an indirect, wholly owned subsidiary of Merrill Lynch, which is the limited partner. The Funds have also entered into separate Distribution Agreements and Distribution Plans with FAM Distributors, Inc.

These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of July 31, 2007, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the respective financial positions of BlackRock Florida Municipal Bond Fund, BlackRock New Jersey Municipal Bond Fund and BlackRock Pennsylvania Municipal Bond Fund as of July 31, 2007, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and their financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.
