Merrill Lynch U.S. Government Mortgage Fund Box 9011 Princeton, NJ 08543-9011 Printed on post-consumer recycled paper Merrill Lynch U.S. Government Mortgage Fund DEAR SHAREHOLDER Economic Review During the six months ended August 31, 2001, the economy remained weak. Second quarter gross domestic product growth is likely to be revised from an initially reported annualized growth rate of 0.7% to flat or even negative. Third-quarter growth is also expected to be slow as the economy struggles to recover. We anticipate a U-shaped recovery and not a quick bounce to the strong growth seen during recent years. As we believe economic growth is currently at, or near bottoming, we expect third-quarter economic data to continue to give conflicting signals. However, there are signs that indicate a muted recovery may take hold sometime in the fourth quarter. Monetary and fiscal policy stimulus have been put in place. The Federal Reserve Board has cut interest rates seven times as of August 31, 2001, for a total of 300 basis points (3.00%). There have been tax cuts and rebate checks that are putting more money into the hands of the consumer. Consumer confidence remains high even in the face of rising unemployment and consumer spending is strong even without the impact of the rebate checks. Housing is strong and leading economic indicators have moved higher for four consecutive months. But again, the recovery will be slow in coming and it will not measure up to the previous period of robust growth. Fiscal Year in Review The fiscal year ended August 31, 2001 was marked with significant changes in both the economic environment and the resulting effect on the term structure of interest rates. Early in the fiscal year, the technology bubble burst, causing valuations in the stock market to plummet. The Federal Reserve Board responded by making a series of short-term interest rate cuts. In addition, there was a general flight to quality. The yield curve was inverted at the start of the fiscal year with three-month Treasury bills yielding 63 basis points more than 30-year Treasury bonds at 5.67%. By fiscal year-end that relationship changed dramatically, with the three-month Treasury bill declining 294 basis points to 3.36% while 30-year interest rates declined just 31 basis points to 5.36%. The effect on price for a given interest rate change is greater on longer-term securities. Even though interest rate declines were greater at the front end of the yield curve, the price movement, and therefore total return, was greater at the longer end of the yield curve. The optimal part of the yield curve was in the five-year area where interest rates declined by 160 basis points and the total return for the year ended August 31, 2001 was +11.89%. By comparison, three-month Treasury bills, two-year notes, and 30-year bonds returned +5.26%, +9.18%, and +8.38%, respectively for the same period. For the fiscal year ended August 31, 2001, the Fund's Class A, Class B, Class C and Class D Shares had total returns of +11.77%, +10.91%, +10.86% and +11.49%, respectively. The unmanaged benchmark Salomon Smith Barney Mortgage Index had a return of +11.87% for the same 12-month period. (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 3 - 5 of this report to shareholders.) The Fund provided good relative total returns for the fiscal year ended August 31, 2001. Our strategy to overweight mortgage securities proved to be correct. Also correct was our focus on securities that offered some prepayment protection. In a declining interest rate environment, where many mortgages trade at premium prices, prepayment on mortgage securities can hurt total return. We avoided significant prepayment risk by weighting the portfolio in lower coupon securities that traded at a discount price. We also kept a large portion of the portfolio in multi-family securities, where there are contractual prohibitions against early prepayment. Merrill Lynch U.S. Government Mortgage Fund, August 31, 2001 Going forward, we are still quite positive on the mortgage-backed securities (MBS) market even though interest rates have declined to the point where refinancing risk again becomes an important factor. For example, five-year and ten-year Treasury notes ended the period trading at yields of 4.38% and 4.83%, respectively. By comparison, a Fannie Mae 6% coupon MBS was trading at a dollar price of $98.25 or a discount of 1.75%. A Fannie Mae 6.5% coupon was only slightly over par at $101.12. This demonstrates that the coupon and yields are attractive with little, if any, prepayment risk at this time. Even though interest rates are quite low, there is still opportunity for improved performance. First, interest rates probably will drift a little lower as it becomes apparent that the economic recovery is not immediate and far from robust. Second, as we mentioned, the coupon flow is quite attractive compared to Treasury securities. Third, the yield curve is quite steep allowing for the potential of rolling down the curve for positive price gains. Last, we believe that the yield spreads on MBS will tighten closer to historical norms. This tightening of yield spreads typically has the same impact on price and total return as a general decline in interest rates. In Conclusion We thank you for your continued investment in Merrill Lynch U.S. Government Mortgage Fund, and we look forward to discussing our outlook and strategy with you in our next report to shareholders. Sincerely, (Terry K. Glenn) Terry K. Glenn President and Trustee (Gregory Mark Maunz) Gregory Mark Maunz Senior Vice President and Portfolio Manager September 25, 2001 The Fund's transfer agency fee schedule has been amended. Under the revised schedule, the fees payable to Financial Data Services, Inc., the transfer agent for the Fund, now range from $16 to $23 per shareholder account (depending upon the level of service required) or 0.10% of account assets for certain accounts that participate in certain fee-based programs.

Merrill Lynch U.S. Government Mortgage Fund, August 31, 2001 PERFORMANCE DATA About Fund Performance Investors are able to purchase shares of the Fund through the Merrill Lynch Select PricingSM System, which offers four pricing alternatives: * Class A Shares incur a maximum initial sales charge (front-end load) of 4% and bear no ongoing distribution or account maintenance fees. Class A Shares are available only to eligible investors, as detailed in the Fund's prospectus. If you were a Class A shareholder prior to October 21, 1994, your Class A Shares were redesignated to Class D Shares on October 21, 1994. However, in the case of certain eligible investors, the shares were simultaneously exchanged for Class A Shares. * Class B Shares are subject to a maximum contingent deferred sales charge of 4% if redeemed during the first year, decreasing 1% each year thereafter to 0% after the fourth year. In addition, Class B Shares are subject to a distribution fee of 0.50% and an account maintenance fee of 0.25%. These shares automatically convert to Class D Shares after approximately 10 years. (There is no initial sales charge for automatic share conversions.) *Class C Shares are subject to a distribution fee of 0.55% and an account maintenance fee of 0.25%. In addition, Class C Shares are subject to a 1% contingent deferred sales charge if redeemed within one year of purchase. * Class D Shares incur a maximum initial sales charge of 4% and an account maintenance fee of 0.25% (but no distribution fee). None of the past results shown should be considered a representation of future performance. 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 the "Recent Performance Results" and "Average Annual Total Return" tables assume reinvestment of all dividends and capital gains distributions 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.

See Notes to Financial Statements. Merrill Lynch U.S. Government Mortgage Fund, August 31, 2001 NOTES TO FINANCIAL STATEMENTS 1. Significant Accounting Policies: Merrill Lynch U.S. Government Mortgage Fund (the "Fund") is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The Fund's 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. The Fund offers four classes of shares under the Merrill Lynch Select Pricing SM System. Shares of Class A and Class D 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 B, Class C and Class D 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. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments--Securities traded in the over-the-counter market are valued at the last available bid price in the over-the-counter market or on the basis of yield equivalents as obtained from one or more dealers that make markets in the securities. The Fund employs Merrill Lynch Securities Pricing Service ("MLSPS"), an affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), to provide mortgage-backed securities prices for the Fund. 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). Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price as of the close of such exchanges. Securities with a remaining maturity of sixty days or less are valued on an amortized cost basis, which approximates market value. Securities and 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 Trustees of the Fund. (b) Repurchase agreements--The Fund invests in US Government securities pursuant to repurchase agreements. Under such agreements, the counterparty agrees to repurchase the security at a mutually agreed upon time and price. The Fund takes possession of the underlying securities, marks to market such securities and, if necessary, receives additional securities daily to ensure that the contract is fully collateralized. If the counterparty defaults and the fair value of the collateral declines, liquidation of the collateral by the Fund may be delayed or limited. (c) Derivative financial instruments--The Fund may engage in various portfolio investment strategies to increase or decrease the level of risk to which the Fund is exposed more quickly and efficiently than transactions in other types of instruments. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. * Futures contracts--The Fund may purchase or sell financial futures contracts. 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. * Options--The Fund is authorized to write and purchase call and put options. When the Fund writes an option, an amount equal to the premium received by the Fund is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked to market to reflect the current market value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Fund enters into a closing transaction), the Fund realizes a gain or loss on the option to the extent of the premiums received or paid (or gain or loss to the extent the cost of the closing transaction exceeds the premiums paid or received). Written and purchased options are non-income producing investments. Merrill Lynch U.S. Government Mortgage Fund, August 31, 2001 (d) 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 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. Interest income and extended delivery fees are recognized on the accrual basis. The Fund will adopt the provisions to amortize all premiums and discounts on debt securities effective September 1, 2001, as now required under the new AICPA Audit and Accounting Guide for Investment Companies. The cumulative effect of this accounting change will have no impact on the total net assets of the Fund, but will result in a $13,811 decrease to the cost of securities and a corresponding $13,811 increase to net unrealized appreciation, based on debt securities held as of August 31, 2001. (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) Dollar rolls--The Fund sells mortgage-backed securities for delivery in the current month and simultaneously contracts to repurchase substantially similar (same type, coupon and maturity) securities on a specific future date. As of August 31, 2001, no dollar rolls were in effect. (i) Custodian bank--The Fund recorded an amount payable to the custodian bank reflecting an overnight overdraft which resulted from a failed trade which settled the next day. 2. Investment Advisory Agreement and Transactions with Affiliates: The Fund has entered into an Investment Advisory Agreement with FAM. The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. The Fund has also entered into a Distribution Agreement and Distribution Plans with FAM Distributors, Inc. ("FAMD" or the "Distributor"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc. FAM is responsible for the management of the Fund's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Fund. For such services, the Fund pays a monthly fee based upon the average daily value of the Fund's net assets at the following rate: Portion of Average Daily Value of Net Assets: Rate Not exceeding $500 million .500% In excess of $500 million but not exceeding $1 billion .475% In excess of $1 billion but not exceeding $1.5 billion .450% In excess of $1.5 billion but not exceeding $2 billion .425% In excess of $2 billion but not exceeding $2.5 billion .400% In excess of $2.5 billion but not exceeding $3.5 billion .375% In excess of $3.5 billion but not exceeding $5 billion .350% In excess of $5 billion but not exceeding $6.5 billion .325% Exceeding $6.5 billion .300% Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor ongoing account maintenance and distribution fees. The fees are accrued daily and paid monthly at annual rates based upon the average daily net assets of the shares as follows: Account Distribution Maintenance Fee Fee Class B .25% .50% Class C .25% .55% Class D .25% -- Pursuant to a sub-agreement with the Distributor, MLPF&S, a subsidiary of ML & Co., also provides account maintenance and distribution services to the Fund. The ongoing account maintenance fee compensates the Distributor and MLPF&S for providing account maintenance services to Class B, Class C and Class D shareholders. The ongoing distribution fee compensates the Distributor and MLPF&S for providing shareholder and distribution-related services to Class B and Class C shareholders.
