Fixed income markets also performed well, with high yield bond investors enjoying some of the best returns. Total Returns as of January 31, 2005 6-month 12-month ==================================================================================== Equities (Standard & Poor's 500 Index) +8.16% +6.23% - ------------------------------------------------------------------------------------ Fixed income (Lehman Brothers Aggregate Bond Index) +3.81 +4.16 - ------------------------------------------------------------------------------------ Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) +4.80 +4.86 - ------------------------------------------------------------------------------------ High yield bonds (Credit Suisse First Boston High Yield Index) +7.85 +9.81 - ------------------------------------------------------------------------------------ Over the past year, the U.S. economy transitioned from dependence on record monetary and fiscal stimulus to a broad-based, high-productivity, high-profit-margin growth engine. The year also marked the end of one of the most aggressive Federal Reserve Board (Fed) policy periods in history as deflation concerns, prevalent at the beginning of 2004, gave way to modest inflation scares -- notably, food prices in the spring and energy prices in the fall. The Fed more than doubled the federal funds rate, increasing it from 1% to 2.25% in five separate moves between June and December 2004. Yet, even as the Fed raised its target short-term interest rate, long-term bond yields were little changed year over year as buying interest on the part of foreign central banks remained strong. The yield on the 10-year Treasury note stood at 4.14% on January 31, 2005. Despite very strong earnings growth, stocks remained in a narrow trading range for most of 2004, but rebounded nicely in the fourth quarter as election uncertainties and energy price concerns dissipated. January, the first month of the new year and the final month of the current reporting period, was a challenging one for equities as reflected in the -2.44% return of the S&P 500 Index for the month. As we ended the current reporting period, the economy and earnings growth were beginning to slow and the Fed appeared poised to continue moving interest rates higher (and, in fact, raised the federal funds rate another 25 basis points on February 2, 2005). Progress was being monitored on many fronts in Washington, although concerns remained about the structural problems of debt and deficits, as reflected by a significant decline in the U.S. dollar. Looking ahead, the environment is likely to be a challenging one for investors. At the start of the new year, we encourage you to meet with your financial advisor to review your goals and asset allocation and to rebalance your portfolio, as necessary, to ensure it remains aligned with your objectives and risk tolerance. As always, we thank you for trusting Merrill Lynch Investment Managers with your investment assets, and we look forward to serving you in the months and years ahead. Sincerely, /s/ Robert C. Doll, Jr. Robert C. Doll, Jr. President and Trustee MERRILL LYNCH NEW JERSEY MUNICIPAL BOND FUND JANUARY 31, 2005 3 [LOGO] Merrill Lynch Investment Managers A Discussion With Your Fund's Portfolio Manager The Fund significantly outperformed its broad market benchmark and its Lipper category average as we focused on extending the portfolio's average maturity by investing in longer-dated, higher-yielding bonds. Discuss the recent market environment relative to municipal bonds. Long-term bond yields exhibited significant declines over the past six months, even as the Federal Reserve Board (the Fed) continued to raise short-term interest rates. The associated rise in long-term bond prices, which move opposite to yields, came as somewhat of a surprise given the generally positive economic environment. Gross domestic product (GDP) in the United States grew at a rate of 4% in the third quarter of 2004 and was recently estimated at a 3.1% rate for the fourth quarter. During all of 2004, real GDP expanded at a rate of 4%, well above the 3% growth rate registered in 2003. Nevertheless, recent improvements in domestic business activity have been offset by inflationary measures remaining in the 1.5% - 2% range. The Fed's measured program of interest rate increases, which brought the federal funds rate to 2.25% by period-end, had limited market impact as monthly U.S. employment gains remained modest. In addition, strong currency-related demand for U.S. Treasury issues from many foreign governments has helped bolster fixed income bond prices. By the end of January, long-term U.S. Treasury bond yields stood at 4.59%, a decline of 70 basis points (.70%) over the past six months. The 10-year U.S. Treasury note yield was 4.14% at period-end, representing a decline of 45 basis points during the period. While tax-exempt bond yields followed the same pattern as their taxable counterparts, yield volatility in the municipal market was generally more subdued. Long-term revenue bond yields, as measured by the Bond Buyer Revenue Bond Index, fell 44 basis points during the past six months. According to Municipal Market Data, AAA-rated issues maturing in 30 years saw their yields decline 59 basis points to 4.43% while yields on AAA-rated issues maturing in 10 years declined 47 basis points to 3.48%. Long-term tax-exempt bond yield ratios (relative to their taxable counterparts) have remained in the 89% - 96% range, at or above their recent historic average of 85% - 88%. These attractive yield ratios should continue to draw both traditional and non-traditional investors to the municipal market. The positive technical position should allow the municipal market to continue to outperform the taxable market in the coming months. Describe conditions in the State of New Jersey. New Jersey has remained active in the debt market, as evidenced by a dramatic increase in new-issue volume during the six-month period. In October, the state issued approximately $1.5 billion in cigarette tax revenue bonds through the New Jersey Economic Development Authority, the same agency that earlier issued $807.5 million in motor vehicle surcharge revenue bonds. Proceeds from these two securitizations were used to close the gap in the fiscal year 2005 budget. The state continues to refinance and restructure its debt in an effort to achieve short-term savings. However, with a projected budget deficit of more than $4 billion for fiscal year 2006, it is uncertain how the bulk of the gap will be closed. It has been widely reported that personal income taxes will not be raised. In all, New Jersey's projected budget deficit, measured as a percentage of general fund revenues, is among the highest in the nation for the second consecutive year. On a positive note, New Jersey's economy began to show signs of recovery last year and revenue collections in fiscal year 2004 were very favorable to budget. In response, the state increased spending in 2005. For the first five months of fiscal year 2005, however, revenue collections were slightly unfavorable to budget by 1.9%. How did the Fund perform during the period in light of the existing market conditions? For the six-month period ended January 31, 2005, the Fund's Class A, Class B, Class C and Class I Shares had total returns of +6.53%, +6.21%, +6.16% and +6.48%, respectively, outperforming the +4.80% return of the benchmark Lehman Brothers Municipal Bond Index. (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 6 and 7 of this report to shareholders.) Fund returns also significantly exceeded the +4.72% average return of the Lipper New Jersey Municipal Debt Funds category. Unlike the Lehman Brothers Municipal Bond Index, which measures the performance of municipal bonds nationally, the Lipper category consists of funds that limit their investment to those securities exempt from taxation in the State of New Jersey. 4 MERRILL LYNCH NEW JERSEY MUNICIPAL BOND FUND JANUARY 31, 2005 Fund performance benefited from our strategy of extending the portfolio's average maturity in an effort to capitalize on what we perceived to be value in the longer-dated part of the municipal yield curve. To this end, we sold prerefunded bonds with effective maturities of less than 10 years and reallocated the proceeds in longer-dated bonds. As the yield curve flattened during the past six months, yields inside 10 years increased while yields beyond that range declined. Under these conditions, our strategy of unloading shorter maturities and putting the assets to work further out on the curve benefited performance. Also contributing positively to the Fund's relative results was favorable security and credit selection. We held a fairly high percentage of assets in low-investment and non-investment grade issues, as well as non-rated bonds. A continued contraction in credit spreads over the past six months allowed lower-rated issues to outperform higher-quality municipal bonds. In addition, the increased yields offered by these lower-quality credits helped to maintain the portfolio's competitive yield, an incremental advantage that was additive to the Fund's total return over the past six months. What changes were made to the portfolio during the period? We continued with our strategy of extending the Fund's average maturity as bonds were called from the portfolio and compelling investment opportunities arose. In one instance, a corporate-related holding with a fairly large coupon was called by the issuer. This presented us with an opportunity to reallocate the proceeds into longer-dated, higher-quality issues that came to market as New Jersey municipal issuance increased dramatically. In fact, we saw $12 billion in new long-term debt issued in the state over the past six months -- 130% more than the same six-month period a year ago. Much of the new-issue volume was made up of deficit financing as the state sought to close its fiscal year 2005 budget gap. This presented us with sufficient opportunity to accomplish our restructuring goals and made for some attractive opportunities given the relative cheapness of the New Jersey municipal market. In terms of sector exposure, we increased the Fund's position in housing bonds, an area where we had been underweighted. The active issuance during the period gave us an opportunity to establish more of a market weighting in this sector. How would you characterize the Fund's position at the close of the period? We maintained a relatively neutral posture with respect to interest rates, as we expect rates to increase, but at a measured pace. (In fact, the Fed increased its target interest rate another 25 basis points shortly after the close of the period, on February 2.) The portfolio's duration is on par with that of its peers, which we believe positions the Fund to provide competitive returns whether presented with either a rising or a falling interest rate environment. We continue to focus on the Fund's credit profile as a means to generate above-average performance. While credit spreads have already narrowed substantially, we do not believe they are likely to widen in the very near term. Fundamentals remain positive for corporate earnings growth, and we continue to see demand for high yield municipal product, as evidenced by sustained flows into high yield municipal bond funds. Taken together, we believe this should further sustain investors' appetite for spread product, supporting our investment emphasis in this area. Theodore R. Jaeckel Jr., CFA Vice President and Portfolio Manager February 9, 2005 MERRILL LYNCH NEW JERSEY MUNICIPAL BOND FUND JANUARY 31, 2005 5 [LOGO] Merrill Lynch Investment Managers Performance Data About Fund Performance Investors are able to purchase shares of the Fund through multiple pricing alternatives: o Class A Shares incur a maximum initial sales charge (front-end load) of 4% and an account maintenance fee of 0.10% per year (but no distribution fee). o Class B Shares are subject to a maximum contingent deferred sales charge of 4%, declining to 0% after six years. All Class B Shares purchased prior to December 1, 2002 will maintain the four-year schedule. In addition, Class B Shares are subject to a distribution fee of 0.25% per year and an account maintenance fee of 0.25% per year. These shares automatically convert to Class A Shares after approximately ten years. (There is no initial sales charge for automatic share conversions.) o Class C Shares are subject to a distribution fee of 0.35% per year and an account maintenance fee of 0.25% per year. In addition, Class C Shares are subject to a 1% contingent deferred sales charge if redeemed within one year of purchase. o Class I Shares incur a maximum initial sales charge (front-end load) of 4% and bear no ongoing distribution or account maintenance fees. Class I Shares are available only to eligible investors. None of the past results shown should be considered a representation of future performance. Current performance may be lower or higher than the performance data quoted. Refer to www.mlim.ml.com 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 following tables 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 cost. Dividends paid to each class of shares will vary because of the different levels of account maintenance, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders. The Fund's Investment Adviser agreed to reimburse a portion of its fee. Without such reimbursement, the Fund's performance would have been lower.

MERRILL LYNCH NEW JERSEY MUNICIPAL BOND FUND JANUARY 31, 2005 7 [LOGO] Merrill Lynch Investment Managers Disclosure of Expenses Shareholders of this 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 12(b)-1 fees, and other Fund expenses. The following example (which is based on a hypothetical investment of $1,000 invested on August 1, 2004 and held through January 31, 2005) is intended to assist shareholders both in calculating expenses based on an investment in the 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 the 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 this Fund 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.

All such adjustments are of a normal, recurring nature. The Fund offers multiple classes of shares. Shares of Class A and Class I are sold with a front-end sales charge. Shares of Class B and Class C 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 Class A, Class B and Class C Shares bear certain expenses related to the account maintenance of such shares, and Class B and Class C 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 account maintenance and distribution expenditures (except that Class B shareholders may vote on certain changes to the Class A distribution plan). Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses on investments are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments -- Municipal bonds are traded primarily in the over-the-counter markets and are valued at the last available bid price in the over-the-counter 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 Trust under the general direction of the Board of Trustees. Such valuations and procedures are reviewed periodically by the Board of Trustees of the Fund. 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. In the case of options traded in the over-the-counter market, valuation is 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 Fund's pricing service. Short-term investments with a remaining maturity of 60 days or less are valued at amortized cost, which approximates market value, under which method the investment is valued at cost and any premium or discount is amortized on a straight line basis to maturity. 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 -- The Fund may engage in various portfolio investment strategies both to increase the return of the Fund and to hedge, or protect, its exposure to interest rate movements and movements in the securities markets. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. o Financial futures contracts -- The Fund may purchase or sell financial futures contracts and options on such futures contracts. 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 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 -- The Fund may enter into forward interest rate swaps. In a forward interest rate swap, the Fund 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. When the agreement is closed, the Fund records a realized gain or loss in an amount equal to the value of the agreement. (c) Income taxes -- It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially 20 MERRILL LYNCH NEW JERSEY MUNICIPAL BOND FUND JANUARY 31, 2005 Notes to Financial Statements (continued) all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. (d) 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. Interest income is recognized on the accrual basis. The Fund amortizes all premiums and discounts on debt securities. (e) Prepaid registration fees -- Prepaid registration fees are charged to expense as the related shares are issued. (f) 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. (g) 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. 2.
