Economic Environment For the most part, the economy remained on solid footing throughout the past 12 months. Gross domestic product (GDP) grew at an annualized rate of 3.3% in the second quarter of 2004, 4% in the third quarter and 3.8% in the fourth quarter. An advanced estimate for the first quarter of 2005 placed GDP growth at a slower-than-expected 3.1%, although that figure was later revised upward to 3.5%. Still, annualized GDP growth for all of 2004 came in at 4.4%, well ahead of the 3% growth rate recorded in 2003. In the past several months, the major themes have centered on inflation and, in particular, the price of oil. Inflation showed signs of increasing at both the producer and consumer levels, but still remained fairly subdued. Nevertheless, the Federal Reserve Board (Fed) continued to target higher interest rates to combat inflation expectations. The federal funds rate stood at 2.75% by the end of the period, the result of seven consecutive rate hikes since June 2004, and was raised once more to 3% on May 3. The Fed maintained its commitment to a measured monetary tightening program even in the face of rising oil prices, which many feared could increase inflationary pressures and threaten the economic growth forecasts at certain points throughout the period. Nevertheless, the oil price shocks were largely absorbed by the markets. As short-term interest rates rose in symphony with the Fed rate hikes, long-term rates remained stubbornly low, producing what Fed Chairman Alan Greenspan in February described as a "conundrum." The result was a considerable flattening of the yield curve over the past 12 months, with the two-year Treasury yield increasing from 2.31% to 3.66%, while the yield on the 10-year Treasury note declined from 4.53% to 4.21%. Notably, the short end of the yield curve has remained steep, with a 76-basis-point (0.76%) spread between the three-month and two-year Treasury at period-end. Issuance of Treasury securities continued to increase, largely to fund the significant twin deficits. Notably, the heavy supply continued to be absorbed by foreign interest in holding U.S. assets, despite the declining value of the U.S. dollar. The Treasury has remained prudent in its issuance of bills by adjusting the size of the weekly four-week bill as a cash management tool. In addition, the government's increased collection of both corporate and individual payroll taxes -- coincident with improving employment -- has helped offset the need for additional supply in the short end. Portfolio Matters Merrill Lynch Premier Institutional Fund Merrill Lynch Institutional Fund For the 12-month period ended April 30, 2005, Merrill Lynch Premier Institutional Fund's net yield was 1.77%. The Fund's seven-day net annualized yield as of April 30, 2005, was 2.63%. The Fund's average portfolio maturity at April 30, 2005, was 68 days, compared to 60 days at October 31, 2004, and 67 days at April 30, 2004. During the period, the Fund's average portfolio maturity ranged from a low of 49 days to a high of 73 days. 1 For the 12-month period ended April 30, 2005, Merrill Lynch Institutional Fund's net yield was 1.70%. The Fund's seven-day net annualized yield as of April 30, 2005, was 2.63%. The Fund's average portfolio maturity at April 30, 2005, was 50 days, compared to 54 days at October 31, 2004, and 57 days at April 30, 2004. During the period, the Fund's average portfolio maturity ranged from a low of 39 days to a high of 61 days. The positioning of the Funds enhanced performance for the bulk of the fiscal year. Throughout the period, our above-average exposure to floating rate securities allowed the portfolios' yields to increase in lockstep with the Fed's short-term interest rate hikes. We had the Funds in a barbell position early in the period, which required us to purchase some securities further out on the yield curve to balance our exposure at the short end. Although these securities recently underperformed, this strategy clearly benefited the Funds' performance early in the period. Heading into the fiscal year, the Funds had a large overweight position in floating rate securities (approximately 60% of each portfolio's net assets). Because their coupons continuously reset, floating rate securities provide significant protection against the risk of rising interest rates. As a result of our floating positions, we were able to maintain a more neutral duration relative to the market, when a rising rate environment typically might call for a slightly short duration posture. Early in the fiscal year, with the Fed clearly preparing to begin tightening monetary policy, we tried to keep approximately 15% to 20% of the Funds' assets in securities with overnight maturities for liquidity. With the remainder of the portfolio, we generally focused on the six- and nine-month areas of the yield curve -- sectors we believed were priced correctly given our view that we would likely see 25-basis-point rate hikes at every Federal Open Market Committee meeting through the second quarter of 2005. We were not willing to venture any further out on the yield curve, as we believed there was little value from a risk/reward standpoint. Conditions in Premier Institutional Fund changed markedly in the last quarter of the fiscal year. During this time, we were forced to focus solely on shareholder liquidity as the Fund's assets fell from $36.9 billion on January 31, 2005, to $18.7 billion at period-end. This effectively lengthened the Fund's weighted average maturity, which also limited our ability to invest further out on the yield curve. We continue to target an average portfolio duration in the 60-day range for each fund, reflecting our cautiously constructive view that there are sectors of the yield curve that represent value. Although the federal funds rate is sure to increase over the near term, we believe that future policy decisions in the third and fourth quarter of 2005 will be more dependent on the economic data releases. Several factors appear to be threatening the consumer and ultimately could threaten sustainable economic growth: Higher interest rates may curtail the wealth effect generated by housing prices and mortgage refinancing; job creation has not proved consistent enough to support wage growth; and oil prices, while possibly inflationary, seem to pose a greater risk in reducing discretionary spending. While our strategy for much of the fiscal year called for significant exposure to variable rate notes, the liquidity needs of the Funds have led us to reduce our exposure to this sector. We will look to re-establish our floating rate positions and will focus on securities with rates tied to indexes such as the fed funds and prime rates that perform best in what could be a prolonged flat yield curve environment. In our view, there is value in the six-, nine- and 12-month sectors, as we believe they are fairly priced and provide extremely attractive yields given the steepness of the curve in the front end. We believe the federal funds target will be in the 3.5% to 4% range by year-end, and we may shift to a slightly longer portfolio duration bias should yields rise in anticipation that the Fed will take a more aggressive strategy. 2 Merrill Lynch Government Fund For the 12-month period ended April 30, 2005, Merrill Lynch Government Fund's net yield was 1.66%. The Fund's seven-day net annualized yield as of April 30, 2005, was 2.63%. The Fund's average portfolio maturity at April 30, 2005, was 43 days, compared to 40 days at October 31, 2004, and 58 days at April 30, 2004. During the period, the Fund's average maturity ranged from a low of 35 days to a high of 58 days. While the Fund's performance weathered periods of inordinate asset declines as the yield curve steepened, it improved once our asset base exhibited signs of stability. During the fiscal year, more than 85% of the Fund's assets comprised overnight repurchase agreements and floating rate securities, which were able to adjust quickly to market rates. Structurally, we employed a barbell strategy throughout the year. This involved emphasizing the very front end of the market (overnight repurchase agreements and floating rate securities) for liquidity and as a hedge against rising interest rates. At the other end of the barbell, we initially purchased longer-dated securities for yield enhancement and price appreciation. As the Fed embarked on its "measured" monetary tightening campaign in June 2004, short-term interest rates began to rise and continued to advance throughout the Fund's fiscal year. This gave us reason to approach longer-dated securities with caution, as their market value tends to suffer more in a rising interest rate environment. As market conditions appeared oversold, we added small positions of late-2005 maturities at yields attractive to financing levels. However, much of our focus was on meeting the high demand of investor liquidity while maintaining a cautious outlook on interest rates and providing a competitive return. Assets under management fell during the year by nearly 40%, which reflected higher interest rates and investors' aversion to the debt of the two government-sponsored entities (GSEs), Fannie Mae and Freddie Mac. The prices of these issues declined amid concerns about accounting irregularities and the uncertainty regarding the possibility of increased federal government oversight of the GSEs. We maintain our cautious outlook on the fixed income market. The interesting question centers on when the Fed may become more data-dependent in determining monetary policy. Consensus expectations at this point are that more measured interest rate increases are forthcoming until the federal funds rate reaches a "neutral" level (relative to inflation) in the area of 3.5%-4.0%. Current economic data suggest that the recent "soft patch" -- highlighted by the advanced first quarter GDP release of an unexpectedly low 3.1% (revised in late May to 3.5%) -- may be short-lived and that final first quarter GDP growth may be revised modestly higher. On the agency front, we anticipate that any forthcoming legislation will produce a stronger regulator of the GSEs and limited new supply. As a result, we believe the agency market will strengthen and quality spreads will narrow. 3 Merrill Lynch Treasury Fund For the 12-month period ended April 30, 2005, Merrill Lynch Treasury Fund's net yield was 1.51%. The Fund's seven-day net annualized yield as of April 30, 2005, was 2.52%. The Fund's average portfolio maturity at April 30, 2005, was 49 days, compared to 45 days at October 31, 2004, and 60 days at April 30, 2004. During the period, the Fund's average maturity ranged from a low of 26 days to a high of 60 days. Our goal was to maintain a conservative strategy, which was reflected in the portfolio's average maturity dipping into the low 30-day area for extended periods. Overall, we managed the Fund conservatively in response to a rising interest rate environment. Early in the period, we utilized the very front end of the Treasury yield curve for liquidity and longer-dated notes (the one- to two-year sector) for incremental yield. As it became apparent that the Fed would shift to a more restrictive monetary policy, we sought to restructure the Fund by paring longer-dated notes and utilizing a more bullet-structured portfolio, in which the maturities of our securities are highly concentrated in one segment of the yield curve. We believed that by utilizing a bullet rather than a barbell approach, we would be able to reinvest the portfolio's assets more quickly into securities at current market rates without sacrificing liquidity. Our focus was to reduce the Fund's average maturity to the low 40-day area. For the most part, we concentrated our investments within the three-month sector to maintain a strong liquidity base while allowing us to maintain a yield competitive with that of the market. By the third quarter of 2004, a shift in the Treasury yield curve caused by smaller Treasury bill auctions allowed the Fund to prepare for year-end liquidity needs. That is, the reduced issuance of Treasury bills resulted in increased demand for these securities and caused the yield curve to steepen. The effect of the year-end asset growth and diminished bill supply forced the Fund to invest in shorter maturities at punitive levels, which had taken its toll on the Fund's performance, particularly in the early months of 2005. Nevertheless, we resolved to maintain a more conservative stance in the face of continued rising interest rates. Fund performance improved late in the period, as we modestly extended the Fund's weighted average maturity in light of diminished Treasury bill supply and as investors sought Treasuries as a safe haven. For the most part, our liquidity base shifted between the four-week and the two-month sector as supply dictated. We focused on the six-month sector as the fulcrum of the curve for incremental yield and trading opportunities. Since the Treasury bill market has a tendency to follow the technical dynamics rather than the fundamental aspects of the environment, we have been more inclined to invest in smaller issues, which will ultimately garner stronger trading opportunities. Treasury notes have offered limited opportunities for the Fund since most issues trade at or below yields of comparable Treasury bill maturities. Looking ahead, we believe the Fund's conservative average life allows us to be well positioned for the anticipated market environment. The inclination of the Fed to continually raise rates at a measured pace, coupled with a projected reductions in the amount of Treasury bill issuance, should result in a steep yield curve. Despite recent indicators pointing to higher economic growth, a flight to quality has allowed the market to be temporarily range-bound. New asset inflows have compelled us to maintain a larger liquidity base. On the longer end, we still favor the five- to six-month sector as the prospects of limited Treasury bill issuance looms. 4 Merrill Lynch Institutional Tax-Exempt Fund For the 12-month period ended April 30, 2005, Merrill Lynch Institutional Tax-Exempt Fund's net yield was 1.37%. The Fund's seven-day net annualized yield as of April 30, 2005, was 2.52%. The Fund's average portfolio maturity at April 30, 2005, was 23 days, compared to 53 days at October 31, 2004, and 48 days at April 30, 2004. During the period, the Fund's average maturity ranged from a low of 21 days to a high of 59 days. We began the fiscal year with a more cautious approach to the short-term municipal market. Strong job growth early in the period, as well as inflationary concerns, led investors to believe that the Fed would soon end its accommodative monetary policy. One-year municipal note yields increased, creating a spread versus variable rate demand notes (VRDN) of over 60 basis points. Despite the attractiveness of the municipal note yield pick-up, we limited our purchases of municipal notes to maintain exposure levels that were close to our iMoneyNet peer group average. The Fed began and continued to increase the target federal funds rate in 25-basis-point increments seven times from June 2004 to March 2005. The target rate stood at 2.75% at the end of the period. Market participants viewed these interest rate increases as a continuation of the Fed's efforts to bring the federal funds rate to a neutral level. The one-year London Interbank Offer Rate (LIBOR) rose approximately 230 basis points to the 3.70% range over the period while yields on one-year municipal notes increased roughly 170 basis points to the 2.80% range. During this time, we changed our investment strategy to a conservative approach as we focused on VRDN securities as a primary investment. This approach allowed the Fund to participate in the yield increases as they occurred. As demand for VRDN securities increased and their yields became more volatile, we used tax-exempt commercial paper (TECP) as an alternative to help balance the Fund's holdings. The TECP helped to stabilize the Fund's yield from volatile VRDN yield swings without committing to the uncertainty of longer-dated securities. The reduced participation in municipal notes allowed the Fund's average life to decline to the 25-day range, which was similar to our iMoneyNet peer group average. The Fund continued to experience volatile growth. It began the fiscal year with $11.0 billion in net assets, which grew to a high of $14.4 billion in mid-February before income-tax-related redemptions caused assets to decline to $12.6 billion by the end of the period. An underweight in municipal notes and a higher weighting of VRDN and TECP securities benefited the Fund's performance relative to its iMoneyNet peer group during the period. With the Fed embarking on a tightening agenda, the portfolio has been well positioned to take advantage of higher interest rates while preserving shareholder principal. The upcoming period generally is driven by supply and demand and can lead to a volatile environment for short-term tax-exempt securities. It is widely anticipated that the Fed will continue to increase short-term interest rates. In addition, we are in the midst of seasonal income-tax-related redemptions out of money market funds. The spring and summer are also traditionally characterized by heavy new issuance of fixed rate notes. We believe 5 the combination of these factors should lead to higher rates over the near term, which may create an opportunity to purchase securities at higher yields and lock in a higher rate of accrual for the Fund. Furthermore, the portfolio's fixed rate notes that mature over the next several months should provide us with an opportunity to reinvest at higher interest rates. We will continue to closely monitor the changing market conditions while adjusting our investment strategy accordingly. We continue to monitor the Fund's credit quality while looking to offer our shareholders an attractive tax-exempt yield.

The following example (which is based on a hypothetical investment of $1,000 invested on November 1, 2004 and held through April 30, 2005) is intended to assist shareholders both in calculating expenses based on an investment in the Funds 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 Funds' 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 the 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, shareholders expenses would have been higher.

See Notes to Financial Statements. 22 - -------------------------------------------------------------------------------- Merrill Lynch Funds For Institutions Series Notes to Financial Statements ================================================================================ 1. 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 Lynch 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, 2005). 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 Fund 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 investment companies and to distribute all of its taxable and tax-exempt income to its shareholders. Therefore, no federal income tax provision is required. 23 - -------------------------------------------------------------------------------- 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 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. Merrill Lynch Institutional Tax-Exempt Fund, for the year ended April 30, 2005, $5,318 has been reclassified between undistributed net investment income and accumulated net realized loss as a result of permanent differences attributable to amortization methods on fixed income securities. These reclassifications have no effect on net assets or net asset value 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, 2005, FAM waived a portion of its fees amounting to $5,242,735 for the Government Fund and $1,822,897 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. Effective May 13, 2005, FAM agreed to voluntarily waive a portion of the administrative fee for the Premier Institutional Fund. FAM may discontinue waiver of the fee in whole or in part at any time without notice. 24 - -------------------------------------------------------------------------------- Merrill Lynch Funds For Institutions Series Notes to Financial Statements -- Continued ================================================================================ All officers and certain trustees of the Trust are affiliated with Merrill Lynch & Co., Inc. 3.

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 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 April 30, 2005, by correspondence with the custodian. 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 financial position of each of the respective Funds of Merrill Lynch Funds For Institutions Series as of April 30, 2005, and 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 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.

State laws vary as to whether and what percentage of the Fund's dividend income may be exempt from state income tax, often based upon the percentage of the Fund's income that is derived from investing in obligations issued within that state. We recommend that you consult your tax advisor to determine if any portion of the dividends you received is exempt from state income taxes. Additionally, the Fund paid a short-term capital gain distribution of $0.000005802 and a long-term capital gain distribution of $0.000006988 per share to shareholders of record on December 20, 2004. 29 -

See Notes to Financial Statements. 114 - -------------------------------------------------------------------------------- Master Institutional Money Market Trust Notes to Financial Statements - -------------------------------------------------------------------------------- 1. 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 some of 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 (the "Funds") invest in U.S. Government & Agency securities pursuant to repurchase agreements with member banks of the 115 - -------------------------------------------------------------------------------- Master Institutional Money Market Trust Notes to Financial Statements -- Continued - -------------------------------------------------------------------------------- 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 Fund 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. Effective May 13, 2005, FAM agreed to voluntarily waive a portion of the advisory fee for the Master Premier Institutional Fund. FAM may discontinue waiver of the fee in whole or in part at any time without notice. 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, 2005, the Master Premier Institutional Fund and the Master Institutional Fund did not have any securities on loan. 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, in a private investment company managed by MLIM, LLC or in registered money market funds advised by FAM or it affiliates. For the year ended April 30, 2005 the Master Premier Institutional Fund earned $1,137,492 in dividend and interest income from affiliates on investments made with cash collateral. For the year ended April 30, 2005, MLIM, LLC received $485,614 in securities lending agent fees from the Master Premier Institutional Fund. All officers and certain trustees of the Trust are affiliated with Merrill Lynch & Co., Inc. 116 - -------------------------------------------------------------------------------- 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, 2005, and 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 and for the period January 14, 2002 (commencement of operations) to April 30, 2002. 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 and supplementary data are free of material misstatement. The Master 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 Master 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 April 30, 2005, 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 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, 2005, 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 and for the period January 14, 2002 (commencement of operations) to April 30, 2002, 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 all of the registrants the Committee oversees. 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.
