Market Environment Short-term interest rates were quite volatile during the 12-month period ended April 30, 2004, and ended the year significantly higher than where they began. The yield on the two-year U.S. Treasury note opened the period at 1.49% on April 30, 2003 and closed at 2.32% on April 30, 2004. Early in the period, when fears of poor economic data and deflation were at their highest, the short end of the yield curve rallied amid speculation that the Federal Reserve Board would potentially slash interest rates to a level below 1.00%. The Fed had reduced the target Federal Funds rate to 1.00% in June 2003. Consequently, as fiscal stimulus and the effects of lower interest rates began to have a positive effect on the economy, the yield curve steepened. Following an extended period of limited job growth, the U.S. Department of Labor reported that non-farm payrolls jumped by 308,000 and 288,000 in March and April 2004, respectively. The yield curve steepening accelerated in response to the employment data. The curve between the Federal Funds rate and the two-year Treasury note was as steep as 1.60%, reflecting the markets' perception that the Fed was behind the curve and would need to tighten monetary policy aggressively. Fund Performance Merrill Lynch Premier Institutional Fund The Fund's net yield for the year ended April 30, 2004 was 1.05%. The Fund's seven-day net annualized yield as of April 30, 2004 was .98%. The Master Premier Institutional Fund's average portfolio maturity at April 30, 2004 was 67 days, compared to 65 days at October 31, 2003. Merrill Lynch Institutional Fund The Fund's net yield for the year ended April 30, 2004 was .97%. The Fund's seven-day net annualized yield as of April 30, 2004 was .90%. The Master Institutional Fund's average portfolio maturity at April 30, 2004 was 57 days, unchanged from 57 days at October 31, 2003. Merrill Lynch Government Fund The Fund's net yield for the year ended April 30, 2004 was .94%. The Fund's seven-day net annualized yield as of April 30, 2004 was .87%. The Fund's average portfolio maturity at April 30, 2004 was 58 days, compared to 57 days at October 31, 2003. Merrill Lynch Treasury Fund The Fund's net yield for the year ended April 30, 2004 was .80%. The Fund's seven-day net annualized yield as of April 30, 2004 was .75%. The Fund's average portfolio maturity at April 30, 2004 was 60 days, compared to 58 days at October 31, 2003. 1 Merrill Lynch Institutional Tax-Exempt Fund The Fund's net yield for the year ended April 30, 2004 was .84%. The Fund's seven-day net annualized yield as of April 30, 2004 was .88%. The Master Institutional Tax-Exempt Fund's average portfolio maturity at April 30, 2004 was 48 days, compared to 54 days at October 31, 2003. Portfolio Strategy Merrill Lynch Premier Institutional Fund Merrill Lynch Institutional Fund Early in the period, we believed the Federal Reserve Board would leave short-term interest rates low as long as the employment situation was weak and deflation remained a concern. With that in mind, we added some longer-dated callable U.S. agency securities to the portfolios because they offered yield enhancement and the potential for price appreciation. Yield spreads on callable agency securities relative to straight bullet issues were wide, as interest rate volatility remained at the higher end of the historical range for most of the year. We continued to position the Funds in a barbelled manner. Investments were split in the longer-dated callable U.S. agency securities and the three-month-and-under sectors. We employed this strategy because there was no pick-up in yield in the three-month to one-year sectors. The yield curve was flat in this area, with no increase in yield until the 15-month to two-year sector. For the balance of the period, almost 50% of the portfolios' net assets were invested in variable-rate products, which we consider consistent with the short end of our investment spectrum. This position served as part of the barbell trade and to protect the portfolio in case an unforeseen rise in interest rates did occur. Based on our belief that the Fed will tighten monetary policy at one of its next two meetings, we recently restricted our investments to those that would mature before the Federal Open Market Committee meeting on June 30, 2004. Although some longer-dated investments appear attractive to us at current levels, we believe it is prudent to maintain maximum liquidity, especially in the early stages of a tightening cycle. Merrill Lynch Government Fund As the period began, we sought to maintain the Fund's average life in the upper 50-day range. Our strategy was to reduce our dependence on the overnight market while emphasizing fixed-rate structures and floating-rate notes. Against a backdrop of mixed economic reports, a steeper yield curve developed, which enabled us to add longer-dated agency bullets and callable securities with longer non-call features at attractive levels versus Treasury issues. On the floating-rate front, we added prime rate and LIBOR-based floaters that recently were trading at historically tight levels to money market products. For most of the period, our portfolio was concentrated in securities that would mature in 90 days or less and, on the longer end, our focus varied between one and two years, given interest rate levels and the shape of the yield curve. By the end of the period, our goal was to protect the Fund against eventual higher interest rates by increasing our holdings in floating-rate products to nearly half of the portfolio's assets. Recent employment gains have suggested that job growth is catching up with the overall economy. Given that measured interest rate hikes are likely forthcoming, we will look to increase the Fund's liquidity profile, a strategy we believe is prudent in the early stages of a higher interest rate cycle. 2 Merrill Lynch Treasury Fund Throughout most of the period, we sought to maintain the Fund's average life at or near the 60-day limit. We continued to use four-week Treasury bills as a liquidity base for maturing bills and adjusted our focus in the Fund's longer-dated investments as the yield curve shifted directions frequently. As the yield curve steepened and as the market appeared oversold, we extended our focus from the six- to nine-month sector to the 18- to 24-month sector. In the front end of the curve, we sought to enhance yield by selling bills at profits prior to the announcements of their reopenings. We used gains to offset any losses while extending out on the curve for modest incremental yield. We then would reinvest the proceeds from maturing bills into the new bills at higher levels. Currently, the Treasury calendar has favored issuance in the longer end. Increased tax receipts have allowed bill supply to be somewhat stable, and recent steepening in the yield curve suggests a shift of market sentiment toward higher interest rates. Our current structure will favor increasing liquidity, although some longer-dated maturities appear to have value. Merrill Lynch Institutional Tax-Exempt Fund Throughout the period, we used a neutral investment strategy in our approach to the short-term municipal market. Although the period was characterized by improvement in most sectors of the economy, a lack of job growth led market participants to believe that the Federal Reserve Board would keep interest rates low for an extended period of time. Fixed-rate municipal notes continued to offer some incremental yield over variable-rate demand note (VRDN) securities, given the Federal Reserve's bias toward keeping short-term interest rates at their current levels. Although the majority of the municipalities had already brought their annual issuance to market, we looked to maintain our allocation to fixed-rate municipal note holdings close to our peer group average by focusing on attractively priced smaller municipal note deals. However, as the Fund continued to grow, we were obligated at times to pursue volatile VRDN securities and tax-exempt commercial paper (TECP) as investment alternatives. After the Fund's net assets reached a record high of $10.4 billion on December 8, 2003, we began to concentrate on increasing our exposure to highly liquid daily VRDN securities to combat the anticipated high redemptions that ultimately reduced the Fund's assets to $9.5 billion by the end of December. The redemptions were the result of Florida shareholders adjusting their portfolios because of the resident intangibles tax that is still in place. At the same time, we began to anticipate the timing of large subscriptions that would occur as Florida shareholders readjusted their portfolios in January by replacing VRDN securities sold at year-end. Because of the yield advantage of tax-exempt securities versus the after-tax yields of their taxable counterparts, the Fund's assets continued to rise to a record $12.1 billion on March 10, 2004. Fixed-rate municipal note yields declined to approximately 1.05% as limited new municipal issuance gave way to large seasonal demand. In addition, VRDN security and TECP yields traded in the .85% to 1% range. Although we continued to try to match our fixed-rate note percentage to our peer group average, we were selective in our pursuit as yields hovered near historic lows. As the period came to a close, we were experiencing seasonal tax-related redemptions, which allowed the Fund's assets to end the period at $11.0 billion. In addition, we experienced the first indications that economic growth was finally translating into job growth while a rise in oil prices was contributing to an upswing in inflation. 3 In light of the changing economic environment and rhetoric from various Federal Reserve Board members, we are monitoring market participant reaction and are looking to adjust our investment strategy in the upcoming period to a more cautious approach to the short-term municipal market. We are anticipating matching our peer group average in fixed-rate note percentage. However, because of timing issues and our cautious investment approach, the Fund may at times have an average life below our peer group average. As municipalities' annual issuance begins in the upcoming period, we will be selective in our pursuit of fixed-rate notes. We continue to closely monitor credit quality while offering shareholders an attractive tax-exempt yield. We thank you for your investment in Merrill Lynch Funds For Institutions Series, and we look forward to serving your investment needs in the months and years ahead. Sincerely, /s/ Terry K.

Significant Accounting Policies Merrill Lynch Funds For Institutions Series (the "Trust") is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940 as a diversified, open-end management company. The Trust consists of five series, Merrill Lynch Premier Institutional Fund, Merrill Lynch Institutional Fund, Merrill Lynch Government Fund, Merrill Treasury Fund, and Merrill Lynch Institutional Tax Exempt Fund, (collectively, the "Funds"). The Trust's financial statements are prepared in accordance with accounting principles generally accepted in the United States of America, which may require management to make certain estimates and assumptions at the date of the financial statements. The Premier Institutional, Institutional and Institutional Tax Exempt Funds (the "Feeder Funds") invest all of their investable assets in interests in the Master Premier Institutional Fund, Master Institutional Fund, and Master Institutional Tax Exempt Fund (the "Master Funds"), respectively, each a registered investment company having the same investment objective as the Feeder Funds. The value of the Feeder Funds' investments in the Master Funds reflect the Feeder Funds proportionate interest in the Master Funds (approximately 100% for each of the Feeder Funds at April 30, 2004). The results of operations and performance of the Feeder Funds are directly affected by the performance of the Master Funds. The financial statements of the Master Funds, including their schedules of investments, are included elsewhere in this report and should be read in conjunction with the Feeder Funds' financial statements. The following is a summary of significant accounting policies consistently followed by the Trust in conformity with accounting principles generally accepted in the United States of America. (a) Valuation of securities by each of the Master Funds is discussed in Note 1(a) of the Master Funds Notes to Financial Statements which are included elsewhere in this report. The value of the Government and Treasury Funds portfolio securities is determined on the basis of fair value as determined in good faith by the Board of Trustees (the "Trustees") of the Trust. In determining fair value, securities for which market quotations are readily available are valued at market value. Other securities, if any, are valued at their fair value in the best judgement of Fund Asset Management L.P., ("FAM") under procedures established by, and under the supervision of, the Trustees. Securities with remaining maturities of 60 days or less are valued by use of the amortized cost method. For the purpose of valuation, the maturity of a variable rate demand instrument is deemed to be the next coupon date on which the interest rate is to be adjusted. In the case of a floating rate instrument, the remaining maturity is deemed to be the demand notice payment period. 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. (b) It is the Trust's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investments companies and to distribute all of its taxable and tax exempt income to its shareholders. Therefore, no federal income tax provision is required. 20 - -------------------------------------------------------------------------------- Merrill Lynch Funds For Institutions Series Notes to Financial Statements -- Continued - -------------------------------------------------------------------------------- (c) Security transactions are accounted for on the date the securities are purchased or sold (the trade date). Realized gains and losses on investments are computed on the basis of identified cost of the security sold. The Feeder Funds' net investment income includes the Feeder Funds' pro-rata share of the net investment income of the respective Master Funds. The Government Fund and Treasury Fund record interest income (after adjustment for amortization of premium or accretion of discount) as earned. (d) Prepaid registration fees are charged to income as the related shares are sold. (e) Repurchase agreements -- The Government Fund invests in U.S. Government & Agency securities pursuant to repurchase agreements with member banks of the Federal Reserve System or primary dealers in U.S. Government securities. Under such agreements, the bank or primary dealer agrees to repurchase the security at a mutually agreed upon time and price. The Government Fund takes possession of the underlying securities, marks to market such securities daily and, if necessary, receives additional securities to ensure that the contract is adequately collateralized. (f) Accounting principles generally accepted in the United States of America require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. Accordingly, during the current year, $20,775 has been reclassified between undistributed net investment income and accumulated net realized gain and $92,163 has been reclassified between accumulated net realized gain and paid-in capital as a result of permanent differences attributable to amortization methods on fixed income securities and expired capital loss carryforwards. These reclassifications have no effect on net assets or net asset values per share. 2. Investment Advisory Fees and Other Transactions with Affiliates FAM, a subsidiary of Merrill Lynch & Co., Inc., provides investment advisory and corporate administrative services to the Government Fund and Treasury Fund for a fee, subject to certain limitations, at the annual rates listed below. Percentage of Average Daily Net Assets --------------------------------------- Government Fund and Treasury Fund ......... .35% up to and including $500,000,000 plus .335% over $500,000,000 up to and including $750,000,000 plus .32% over $750,000,000 up to and including $1,000,000,000 plus .30% over $1,000,000,000 FAM has agreed to waive a portion of its advisory fees for the Government and Treasury Funds. The effective fee payable to FAM will be at the annual rate of 0.20% for each of the Government and Treasury Funds' average daily net assets. FAM may discontinue waiver of the fee in whole or in part at any time without notice. For the year ended April 30, 2004, FAM waived a portion of its fees amounting to $6,205,326 for the Government Fund and $1,734,934 for the Treasury Fund. FAM provides certain administrative services to the Premier Institutional Fund, Institutional Fund and Institutional Tax-Exempt Fund, for a fee at an annual rate of 0.10%, 0.15% and 0.15%, respectively, of average daily net assets. All officers and certain trustees of the Trust are affiliated with Merrill Lynch & Co., Inc. 21 - -------------------------------------------------------------------------------- Merrill Lynch Funds For Institutions Series Notes to Financial Statements -- Continued - -------------------------------------------------------------------------------- 3.

Dividends for the Premier Institutional, Institutional, Government and Treasury Funds are declared from the total net investment income plus or minus realized gains or losses, if any, on investments. Dividends for the Institutional Tax-Exempt Fund are declared from net investment income excluding discounts earned other than original issue discounts. Net realized capital gains, if any, are normally distributed annually, after deducting prior years' loss carryovers. The Fund may distribute capital gains more frequently than annually in order to maintain the Fund's net asset value at $1.00 per share. 22 - -------------------------------------------------------------------------------- Merrill Lynch Funds For Institutions Series Notes to Financial Statements -- Continued - -------------------------------------------------------------------------------- 5. Trustees' Fees Each Trustee who is not affiliated with the Trust or its adviser is paid an annual retainer fee of $40,000 plus an additional fee of $2,500 for each board meeting attended.

Significant Accounting Policies Master Institutional Money Market Trust (the "Master Trust") is organized as a business trust under the laws of the State of Delaware and is registered under the Investment Company Act of 1940 as an open-end management company. The Declaration of Trust permits the Trustees to issue unlimited beneficial interests in the Master Trust. Beneficial interests in the Master Trust are issued solely in private placement transactions to accredited investors. The Master Trust consists of three series, Master Premier Institutional Fund, Master Institutional Fund, and Master Institutional Tax-Exempt Fund, (collectively, the "Master Funds"). The Master Trust's financial statements are prepared in accordance with accounting principles generally accepted in the United States of America, which may require management to make certain estimates and assumptions at the date of the financial statements. The following is a summary of significant accounting policies consistently followed by the Master Trust in conformity with accounting principles generally accepted in the United States of America. (a) The value of the Master Premier Institutional and Master Institutional Funds' portfolio securities is determined on the basis of fair value as determined in good faith by the Board of Trustees (the "Trustees") of the Master Trust. In determining fair value, securities for which market quotations are readily available are valued at market value. Other securities, if any, are valued at their fair value in the best judgement of Fund Asset Management, L.P. ("FAM") under procedures established by, and under the supervision of, the Trustees. Securities with remaining maturities of 60 days or less are valued by use of the amortized cost method. Master Institutional Tax-Exempt portfolio securities are carried at amortized cost which approximates market value. For the purpose of valuation, the maturity of a variable rate demand instrument is deemed to be the next coupon date on which the interest rate is to be adjusted. In the case of a floating rate instrument, the remaining maturity is deemed to be the demand notice payment period. 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. (b) The Master Funds are treated as partnerships for Federal tax purposes. No provision is made by the Master Funds for federal or state taxes on any taxable income of the Master Funds because each investor in the Master Funds is ultimately responsible for the payment of any taxes. Since the Master Funds' investors are regulated investment companies that invest substantially all of their assets in the Master Funds, the Master Funds normally must satisfy the applicable source of income and diversification requirements under the Internal Revenue Code in order for their respective investors to satisfy them. (c) Realized gains and losses on investments are computed on the basis of identified cost of the security sold. (d) Security transactions are accounted for on the date the securities are purchased or sold (the trade date). Interest income (after adjustments for amortization of premium or accretion of discount) is recorded as earned. (e) Repurchase agreements -- The Master Premier Institutional Fund and the Master Institutional Fund 106 - -------------------------------------------------------------------------------- Master Institutional Money Market Trust Notes to Financial Statements -- Continued - -------------------------------------------------------------------------------- (the "Funds") invest in U.S. Government & Agency securities pursuant to repurchase agreements with member banks of the Federal Reserve System of primary dealers in U.S. Government securities. Under such agreements, the bank or primary dealer agrees to repurchase the security at a mutually agreed upon time and price. The Funds take possession of the underlying securities, mark to market such securities daily and, if necessary, receive additional securities to ensure that the contract is adequately collateralized. (f) Securities lending -- The Master Premier Institutional Fund and Master Institutional Fund may lend securities to financial institutions that provide cash or securities issued or guaranteed by the U.S. government as collateral, which will be maintained at all times in an amount equal to at least 100% of the current market value of the loaned securities. The market value of the loaned securities is determined at the close of business of the Funds and any additional required collateral is delivered to the Funds on the next business day. Where the Funds receive securities as collateral for the loaned securities, they collect a fee from the borrower. The Funds typically receive the income on the loaned securities but do not receive the income on the collateral. Where the Funds receive cash collateral, it may invest such collateral and retain the amount earned on such investment, net of any amount rebated to the borrower. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within five business days. The Funds may pay reasonable finder's, lending agent, administrative and custodial fees in connection with their loans. In the event that the borrower defaults on its obligation to return borrowed securities because of insolvency or for any other reason, the Funds could experience delays and costs in gaining access to the collateral. The Funds also could suffer a loss where the value of the collateral falls below the market value of the borrowed securities, in the event of borrower default or in the event of losses on investments made with cash collateral. 2. Investment Advisory Fees and Other Transactions with Affiliates FAM, a subsidiary of Merrill Lynch & Co., Inc. ("ML&Co."), manages each Master Fund's investments under the overall supervision of The Board of Trustees of The Master Trust. Each Master Fund pays FAM a fee at the annual rate of 0.05% of average daily net assets. The Funds have received an exemptive order from the Securities and Exchange Commission permitting them to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of ML&Co., or its affiliates. As of April 30, 2004, the Master Premier Institutional Fund lent securities with a value of $3,266,700,000 to MLPF&S or its affiliates. The Master Institutional Fund did not have any securities on loan at period end. Pursuant to that order, the Funds have also retained Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of FAM, as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. MLIM, LLC may, on behalf of the Funds, invest cash collateral received by the Funds for such loans, among other things, in a private investment company managed by MLIM, LLC or in registered money market funds advised by FAM or it affiliates. For the period ended April 30, 2004, MLIM, LLC received $4,591,366 in securities lending agent fees. All officers and certain trustees of the Trust are affiliated with Merrill Lynch & Co., Inc. 107 - -------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM - -------------------------------------------------------------------------------- To the Trustees and Investors of Master Institutional Money Market Trust: We have audited the accompanying statements of assets and liabilities of Master Institutional Money Market Trust (the "Master Trust"), consisting of Master Premier Institutional Fund, Master Institutional Fund, and Master Institutional Tax-Exempt Fund (the "Master Funds"), each a separate series of the Master Trust, including the schedules of investments, as of April 30, 2004, the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended and the supplementary data for each of the three years in the period then ended. These financial statements are the responsibility of the Master Trust's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with 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 are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of April 30, 2004, by correspondence with the custodian and brokers. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and supplementary data referred to above present fairly, in all material respects, the financial position of each of the respective Master Funds of Master Institutional Money Market Trust as of April 30, 2004, 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 the supplementary data for each of the three years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the registrant's affiliated service providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are a) consistent with the SEC's auditor independence rules and b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis ("general pre-approval"). However, such services will only be deemed pre-approved provided that any individual project does not exceed $5,000 attributable to the registrant or $50,000 for the project as a whole. Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting.
