CMA TREASURY FUND, MARCH 31, 2005 A Letter From the President Dear Shareholder Financial markets broadly posted positive returns over the most recent reporting period, with international equities providing some of the most impressive results. Total Returns as of March 31, 2005 6-month 12-month U.S. equities (Standard & Poor's 500 Index) + 6.88% + 6.69% Small-cap U.S. equities (Russell 2000 Index) + 8.00 + 5.41 International equities (MSCI Europe Australasia Far East Index) +15.13 +15.06 Fixed income (Lehman Brothers Aggregate Bond Index) + 0.47 + 1.15 Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) + 1.21 + 2.67 High yield bonds (Credit Suisse First Boston High Yield Index) + 3.39 + 7.84 The U.S. economy continued to show resilience in the face of the Federal Reserve Board's (the Fed's) continued interest rate hikes and, more recently, higher oil prices. The Fed's measured tightening program brought the federal funds rate to 2.75% by period-end as the central bank continued its campaign to combat emergent inflation. In fact, business costs have been rising, which is beginning to put pressure on corporate profit margins. Consumer prices have been moving up as well, particularly in the areas of gasoline prices, healthcare costs, housing and education. U.S. equities ended 2004 in a strong rally, but stumbled into negative territory in the first quarter of 2005. On the positive side, corporations have been accelerating their hiring plans, capital spending remains reasonably robust and merger-and- acquisition activity has increased. Offsetting the positives are slowing corporate earnings growth, renewed energy price concerns and the potential for an economic slowdown later this year. International equities, especially in Asia, have benefited from higher economic growth rates. China, in particular, recorded growth of more than 9% in 2004. In the bond market, long-term interest rates finally began to inch higher while significant increases have been recorded on the short end. This resulted in a flattening of the yield curve throughout much of the current reporting period. At March 31, 2005, the two- year Treasury note yielded 3.80% and the 10-year note yielded 4.50%, a difference of 70 basis points (.70%). This compared to a spread of 151 basis points six months earlier and 226 basis points 12 months ago. Looking ahead, the environment is likely to be a challenging one for investors, with diversification and selectivity becoming increasingly important themes. With this in mind, 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, (Robert C. Doll, Jr.) Robert C. Doll, Jr. President and Trustee CMA TREASURY FUND, MARCH 31, 2005 A Discussion With Your Fund's Portfolio Manager We maintained a relatively conservative approach throughout the year in recognition of rising interest rates, particularly at the short end of the yield curve. How did the Fund perform during the fiscal year in light of the existing market conditions? For the 12-month period ended March 31, 2005, CMA Treasury Fund paid shareholders a net annualized dividend of .94%. For the six-month period ended March 31, 2005, the Fund paid shareholders a net annualized dividend of 1.38%. The Fund's seven-day yield as of March 31, 2005 was 1.84%. The Fund's average portfolio maturity at March 31, 2005, was 48 days. This compared to 67 days at September 30, 2004 and 63 days at March 31, 2004. We employed a barbell strategy throughout the past year. That is, we emphasized the very front end of the market for liquidity and looked to longer-dated securities for yield enhancement and price appreciation. Overall, the Fund delivered above-average results relative to its peers. This is attributed to our focus on managing the portfolio's average life and exposure to longer-dated holdings. For the most part, the economy remained on solid footing throughout the past 12 months. Gross domestic product (GDP), which grew at an annualized rate of 4.5% in the first quarter of 2004, slowed to 3.3% in the second quarter before increasing to 4% in the third quarter and 3.8% in the fourth quarter. A similar level of growth is expected in the first quarter of 2005. Gains in personal income contributed to GDP growth in 2004, although job creation has not been as robust as in previous economic recoveries. In the past several months, the major themes have centered on inflation and, in particular, the price of oil. Inflation appeared to pick up at the producer level, although a similar increase was not recorded at the consumer level. Nevertheless, the Federal Reserve Board (the Fed) continued to target higher interest rates to combat inflation expectations. Since June 2004, the Fed has raised the federal funds rate 25 basis points (.25%) at each Federal Open Market Committee meeting, bringing the federal funds target rate to 2.75% by period-end. The Fed maintained its commitment to a measured monetary tightening program even in the face of a rising oil price, which many feared could increase inflationary pressures and threaten the economic growth forecasts at certain points throughout the period. Nevertheless, oil price shocks were largely absorbed by the markets. As short-term interest rates rose in symphony with the Fed interest rate hikes, long-term interest 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 note yield increasing 220 basis points while the 10-year Treasury note yield increased just 65 basis points during the period. Notably, the short end of the curve has remained quite steep, with a 100 basis point spread between the three-month and two-year Treasury note 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. How did you manage the portfolio during the year? Our average portfolio maturity remained in the 55-day - 65-day range for much of the year, but reached a high of 70 days and a low of 40 days. We continued to employ a barbell strategy, essentially purchasing one-month Treasury bills for liquidity and six-month bills for incremental yield and price appreciation. Our emphasis at each end of the barbell shifted moderately throughout the period, driven by market dynamics, changing yields and our assessment of good relative value. CMA TREASURY FUND, MARCH 31, 2005 As the Fund's fiscal year began last April, interest rates had just backed up with some surprisingly positive employment news. This prompted us to purchase some longer positions in six-month issues to capture the additional yield. The Fed still seemed content to hold interest rates at historic lows at this point; therefore, we were comfortable extending a bit further out. In late May 2004, however, it became apparent that the Fed would begin a tightening program, and we began to shift our focus to the one-month - three-month sectors. As the investors questioned the size and the pace of the interest rate increases, it seemed prudent to avoid locking into longer maturities, particularly if there was no significant yield to be gained. We adapted our approach throughout the following months in search of the best relative value. In the late summer, our analyses began to reveal that the six-month sector offered the best opportunity for yield enhancement and price appreciation. We added securities in this area when they became available, and also continued to purchase three-month bills. In September, we opted to take advantage of government-issued cash management bills. These have shorter maturities than one-month bills, and tend to trade 10 basis points to 15 basis points cheaper. During October, rather than buying one-month bills, we purchased issues maturing in November 2004, which offered significantly higher yields. Late in 2004, we began to target maturities in January and February, carefully avoiding issues maturing in December. As expected, the Fund experienced heavy cash inflows in December, as investors shifted their assets into Treasury funds for year-end tax advantages. Much of this money was redeemed in January. Thus, we placed maturities in January or later to meet the seasonal redemptions. In February and March, we looked to put cash to work in securities with maturities of three months and shorter as we continued to monitor the magnitude of the Fed's interest rate increases. At period-end, there was no clear end to the monetary tightening cycle. For that reason, we were generally not comfortable locking into the longer maturities, although we continue to evaluate the longer-dated sectors for opportunities to pick up additional yield. In fact, we did add some six-month issues to the portfolio at the end of March as spreads between three-month and six-month bills began to widen. How would you characterize the portfolio's position at the close of the period? We remained cautious at period-end given the uncertainty of the Fed's future moves. Consensus expectations are that the Fed will continue its measured approach to interest rate increases until the federal funds rate reaches a "neutral" level (relative to inflation) in the area of 3.5%. However, after seven consecutive 25 basis point interest rate hikes, some are forecasting that the Fed may be prepared to increase the federal funds rate 50 basis points at an upcoming meeting, if the threat of higher inflation becomes more imminent. We maintained adequate liquidity at period-end, which we believe allows us the flexibility to extend at higher levels as opportunities present themselves. Although we do not anticipate a dramatic change in the level of Treasury issuance for the near term, we will take advantage of any technical aberrations in the yield curve. As always, we continue to monitor the economy and interest rates, and will remain ready to adjust our strategy as market dynamics dictate and as compelling opportunities present themselves. The Trust's portfolio composition, as a percent of net assets, at the end of March and as of our last report to shareholders is detailed below: 3/31/05 9/30/04 U.S. Government Obligations 99.1% 99.1% Other Assets Less Liabilities 0.9 0.9 ------ ------ Total 100.0% 100.0% ====== ====== Cindy V. Macaulay Vice President and Portfolio Manager April 7, 2005 CMA TREASURY FUND, MARCH 31, 2005 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 October 1, 2004 and held through March 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. Expenses Paid Beginning Ending During the Period* Account Value Account Value October 1, 2004 to October 1, March 31, March 31, 2004 2005 2005 Actual CMA Treasury Fund $1,000 $1,006.90 $3.30 Hypothetical (5% annual return before expenses)** CMA Treasury Fund $1,000 $1,021.64 $3.33 * Expenses are equal to the Fund's annualized expense ratio .66%, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period shown). Because the Fund is a feeder fund, the expense table reflects the expenses of both the feeder fund and the master fund in which it invests. ** Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in the most recent fiscal half-year divided by 365.

See Notes to Financial Statements. CMA TREASURY FUND, MARCH 31, 2005 Notes to Financial Statements CMA Treasury Fund 1. Significant Accounting Policies: CMA Treasury Fund (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a no load, diversified, open-end management investment company. The Fund seeks to achieve its investment objective by investing all of its assets in the Master Treasury Trust (the "Trust"), which has the same investment objective and strategies as the Fund. The value of the Fund's investment in the Trust reflects the Fund's proportionate interest in the net assets of the Trust. The performance of the Fund is directly affected by the performance of the Trust. The financial statements of the Trust, including the Schedule of Investments, are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. The Fund's financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The percentage of the Trust owned by the Fund at March 31, 2005 was 62.1%. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments--The Fund records its investment in the Trust at fair value. Valuation of securities held by the Trust is discussed in Note 1a of the Trust's Notes to Financial Statements, which are included elsewhere in this report. (b) Investment income and expenses--The Fund records daily its proportionate share of the Trust's income, expenses and realized and unrealized gains and losses. In addition, the Fund accrues its own income and expenses. (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 all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. (d) Prepaid registration fees--Prepaid registration fees are charged to expense as the related shares are issued. (e) Dividends and distributions to shareholders--The Fund declares dividends daily and reinvests daily such dividends (net of non-resident alien tax and backup withholding tax withheld) in additional fund shares at net asset value. Dividends and distributions are declared from the total of net investment income and net realized gain or loss on investments. (f) Investment transactions--Investment transactions in the Trust are accounted for on a trade date basis. 2. Investment Advisory Agreement and Transactions with Affiliates: The Fund has entered into an Administration Agreement with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc. ("PSI"), a wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. The Fund pays a monthly fee at an annual rate of .25% of the Fund's average daily net assets for the performance of administrative services (other than investment advice and related portfolio activities) necessary for the operation of the Fund. The Fund has adopted a Distribution and Shareholder Servicing Plan in compliance with Rule 12b-1 under the Investment Company Act of 1940, pursuant to which Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), an affiliate of FAM, receives a distribution fee from the Fund. The fee is accrued daily and paid monthly at the annual rate of .125% of average daily net assets of the Fund for shareholders who maintain their accounts through MLPF&S. The distribution fee is to compensate MLPF&S financial advisors and other directly involved branch office personnel for selling shares of the Fund and for providing direct personal services to shareholders. The distribution fee is not compensation for the administrative and operational services rendered to the Fund by MLPF&S in processing share orders and administering shareholder accounts. Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co., is the Fund's transfer agent. Interest is earned by the Fund from FDS based on the difference, if any, between estimated and actual daily beneficial share activity, which results in uninvested net proceeds from sales of Fund shares. CMA TREASURY FUND, MARCH 31, 2005 Notes to Financial Statements (concluded) CMA Treasury Fund Certain officers and/or trustees of the Fund are officers and/or directors of FAM, PSI, FDS, and/or ML & Co. 3. Transactions in Shares of Beneficial Interest: The number of shares sold, reinvested and redeemed during the periods corresponds to the amounts included in the Statements of Changes in Net Assets for net proceeds from sale of shares, value of shares reinvested, cost of shares redeemed and shares redeemed in connection with the bulk transfer of WCMA shareholder assets, respectively, since shares are recorded at $1.00 per share. 4. Distribution to Shareholders: The tax character of distributions paid during the fiscal years ended March 31, 2005 and March 31, 2004 was as follows: 3/31/2005 3/31/2004 Distributions paid from: Ordinary income $ 5,837,177 $ 4,167,731 Net long-term capital gains 13,835 -- ------------- ------------- Total taxable distributions $ 5,851,012 $ 4,167,731 ============= ============= As of March 31, 2005, there were no significant differences between the book and tax components of net assets. CMA TREASURY FUND, MARCH 31, 2005 Report of Independent Registered Public Accounting Firm CMA Treasury Fund To the Shareholders and Board of Trustees of CMA Treasury Fund: We have audited the accompanying statement of assets and liabilities of CMA Treasury Fund as of March 31, 2005, and the related statement 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 financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund 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 Fund'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.

See Notes to Financial Statements. CMA TREASURY FUND, MARCH 31, 2005 Notes to Financial Statements Master Treasury Trust 1. Significant Accounting Policies: Master Treasury Trust (the "Trust") is registered under the Investment Company Act of 1940, as amended, and is organized as a Delaware statutory trust. The Declaration of Trust permits the Trustees to issue nontransferable interest in the Trust, subject to certain limitations. The Trust's financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The following is a summary of significant accounting policies followed by the Trust. (a) Valuation of investments--Portfolio securities with remaining maturities of greater than sixty days, for which market quotations are readily available, are valued at market value. As securities transition from sixty-one to sixty days to maturity, the difference between the valuation existing on the sixty-first day before maturity and maturity value is amortized on a straight-line basis to maturity. Securities maturing sixty days or less from their date of acquisition are valued at amortized cost, which approximates market value. For purposes of valuation, the maturity of a variable rate security is deemed to be the next coupon date on which the interest rate is to be adjusted. Other investments and assets for which market quotations are not available are valued at fair value as determined in good faith by or under the direction of the Board of Trustees. (b) Income taxes--The Trust is classified as a partnership for federal income tax purposes. As such, each investor in the Trust is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Trust. Therefore, no federal income tax provision is required. It is intended that the Trust's assets will be managed so an investor in the Trust can satisfy the requirements of Subchapter M of the Internal Revenue Code. (c) 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 (including amortization of premium and discount) is recognized on the accrual basis. 2. Investment Advisory Agreement and Transactions with Affiliates: The Trust has entered into an Investment Advisory Agreement with Fund Asset Management, L.P. ("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. FAM is responsible for the management of the Trust's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Trust. For such services, the Trust pays a monthly fee based upon the average daily value of the Trust's net assets at the following annual rates: .25% of the Trust's average daily net assets not exceeding $500 million; ..175% of the average daily net assets in excess of $500 million, but not exceeding $1 billion; and .125% of the average daily net assets in excess of $1 billion. For the year ended March 31, 2005, the Trust reimbursed FAM $21,552 for certain accounting services. Certain officers and/or trustees of the Trust are officers and/or directors of FAM, PSI, and/or ML & Co. CMA TREASURY FUND, MARCH 31, 2005 Report of Independent Registered Public Accounting Firm Master Treasury Trust To the Investors and Board of Trustees of Master Treasury Trust: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Master Treasury Trust as of March 31, 2005, and the related statement 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 financial highlights for each of the respective periods then ended. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of March 31, 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 financial highlights referred to above present fairly, in all material respects, the financial position of Master Treasury Trust as of March 31, 2005, the results of its operations for the year then ended, and the changes in its net assets for each of the two years in the period then ended and its financial highlights for each of the respective periods then ended, in conformity with U.S. generally accepted accounting principles.
