On February 15, 2006, Merrill Lynch announced plans to combine the firm's investment advisory business, including MLIM, with another highly regarded investment manager -- BlackRock, Inc. ("BlackRock"). We believe this merger of asset management strength will benefit our investors. MLIM is a leading investment management organization with over $576 billion in assets under management globally and 2,757 employees in 17 countries. It offers over 100 investment strategies in vehicles ranging from mutual funds to institutional portfolios. BlackRock is one of the largest publicly traded investment management firms in the United States with $463.1 billion in assets under management and 1,839 employees. It manages assets on behalf of institutional and individual investors worldwide through a variety of equity, fixed income, liquidity and alternative investment products. At the completion of the transaction, which is expected in the third quarter of this year, the resultant firm will be a top-10 investment manager worldwide with over $1 trillion in assets under management.* The combined company will provide a wider selection of high-quality investment solutions across a range of asset classes and investment styles. MLIM and BlackRock possess complementary capabilities that together create a well-rounded organization uniting some of the finest money managers in the industry. At the same time, the firms share similar values and beliefs -- they are focused on delivering excellence on behalf of clients, and both make investment performance their single most important mission. In short, the merger only reinforces our commitment to shareholders. Most of MLIM's investment products -- including mutual funds, separately managed accounts, annuities and variable insurance funds -- eventually will carry the "BlackRock" name. As a shareholder in one or more MLIM-advised mutual funds, you will receive a proxy package in the coming weeks in connection with this transaction. After you receive this information, should you have any questions or concerns, do not hesitate to contact your financial advisor. As always, we thank you for entrusting us with your investment assets, and we look forward to continuing to serve your investment needs with even greater strength and scale as the new BlackRock. Sincerely, /s/ Robert C. Doll, Jr. Robert C. Doll, Jr. President and Chief Investment Officer Merrill Lynch Investment Managers * $1.039 trillion in assets under management as of March 31, 2006. Data, including assets under management, are as of March 31, 2006. WCMA MONEY FUND MARCH 31, 2006 3 A Discussion With Your Fund's Portfolio Manager We maintained the Fund's average maturity in the 55-day to 65-day range throughout the year, although our portfolio composition varied as we found different sectors and asset classes to be attractive. How did the Fund perform during the fiscal year in light of the existing market conditions? For the 12-month period ended March 31, 2006, WCMA Money Fund's Class 1, Class 2, Class 3 and Class 4 Shares paid shareholders net annualized dividends of 2.23%, 2.81%, 3.13% and 3.13%, respectively. For the six-month period ended March 31, 2006, the Fund's Class 1, Class 2, Class 3 and Class 4 Shares paid shareholders net annualized dividends of 2.77%, 3.38%, 3.71% and 3.71%, respectively. The Fund's seven-day yields as of March 31, 2006, were 3.14% for Class 1, 3.71% for Class 2, 4.04% for Class 3 and 4.04% for Class 4. The average portfolio maturity of WCMA Money Fund at March 31, 2006 was 60 days - -- also the average portfolio maturity at September 30, 2005 and March 31, 2005. Economic growth for the first three quarters of 2005 remained firmly above 3% before slipping to 1.7% in the final quarter of the year. The combination of higher oil prices and Hurricanes Katrina and Rita temporarily hindered an otherwise resilient consumer. However, the economy seemed poised to rebound sharply in the first quarter of 2006, with most economists anticipating growth in the 5% range. The Federal Reserve Board (the Fed) continued to raise the federal funds target rate in 25 basis point (.25%) increments over the past year, with the most recent hike on March 28 bringing the target rate to 4.75%. The Treasury yield curve behaved accordingly during the period. In anticipation of higher interest rates early in 2005, the curve was positively sloped, with the yield on the two-year note at 3.80% and the 10-year note at 4.50% on March 31, 2005. As the Fed continually removed accommodative policy, yields on shorter maturities rose to a greater degree than those on longer maturities and the yield curve flattened. As of March 31, 2006, the spread between two-year and 10-year Treasury issues was a mere four basis points, with yields at 4.82% and 4.86%, respectively. Thus, any investments in the two-year sector made early in the six-month period would have proved burdensome as short-term rates climbed to levels exceeding the yields on those holdings. However, in preparation for higher interest rates, the Fund went into the period with a significant allocation to the variable rate sector. This strategy was beneficial as the coupons on these variable instruments were continually reset at higher rates in conjunction with the rising interest rates. How did you manage the portfolio during the period? Throughout the period, our average duration target was consistently in the 55-day to 65-day range, although our portfolio composition varied. As the yield curve shifted and spreads changed, different sectors and asset classes became attractive. We were slightly more cautious early in the fiscal year, when it was apparent that several more interest rate hikes were ahead. Along with variable rate product, we preferred fixed rate instruments in only the six-month and nine-month sectors. We believed those areas offered the greatest value from a risk/reward standpoint, enabling us to capture some steepness in the front end of the curve while limiting our interest rate exposure. Toward the second half of 2005, a lack of floating rate note supply in the market dictated more of a barbelled approach for the Fund. As issuance by the government-sponsored enterprises dropped, spreads on variable rate notes, including corporate and bank names, tightened significantly. Having little interest at those levels, we were then forced to increase our commercial paper and overnight positions until better buying opportunities arose. To maintain the Fund's duration target, the balance of our investments was typically in the 12-month to 15-month sector. We were beginning to favor longer maturities than we had earlier, feeling they offered the greatest potential for capital appreciation. We also saw value in two-year callable issues, believing volatility and swap spreads were at attractive levels and would trend lower once the Fed reached neutral policy. Heading into the fourth quarter, it seemed that higher home heating costs, when combined with already high gasoline prices, would soften consumer demand. If this were to occur, the spread between the federal funds rate and the two-year Treasury yield would likely invert, as the market would anticipate the end of the monetary tightening cycle. 4 WCMA MONEY FUND MARCH 31, 2006 How would you characterize the portfolio's position at the close of the period? In the early part of 2006, the employment data remained firm and inflation seemed well contained. It would seem that the Fed's 15 interest rate hikes over the past two years may eventually hinder consumption, as home equity borrowing and refinancing activity has slowed. However, most recently, we have adopted a slightly more defensive posture, with more than 35% of the portfolio's net assets in overnight investments. We believe the Fed is clearly poised for another quarter-point move in May, but currently the federal funds futures contracts are pricing in only a 56% chance for an additional move in June. We believe there is a greater risk that the Fed will overshoot, as it often does, and raise the target interest rate too high. If that is the case, there is little value in the very front end of the curve. We have added some one-year fixed rate bank product with yields approaching 5.25%, feeling we are fairly compensated even in the event of two additional interest rate hikes. As spreads on variable rate notes have reached more attractive levels, we have readdressed those sectors. However, we have focused exclusively on the prime and federal funds indexes, based on our belief that they will outperform the others over the next 12 months. We still believe the spread on the federal funds rate to the two-year Treasury note will invert; however, the timing may be further out than we had originally anticipated. Thus, we will look for the longer sectors to be more fairly priced before we begin to position the Fund for a stable-rate, low-volatility environment, which we expect by the second half of 2006. The portfolio's composition, as a percent of net assets, at the end of March and as of our last report to shareholders is detailed below: - -------------------------------------------------------------------------------- 3/31/06 9/30/05 - -------------------------------------------------------------------------------- Bank Notes ............................................ 1.3% 3.3% Certificates of Deposit ............................... 4.9 4.9 Certificates of Deposit--European ..................... 2.1 3.1 Certificates of Deposit--Yankee* ...................... 19.6 12.7 Commercial Paper ...................................... 21.4 33.8 Corporate Notes ....................................... 18.6 3.0 Funding Agreements .................................... 6.7 7.4 Master Notes .......................................... -- 1.0 Medium-Term Notes ..................................... -- 10.2 Promissory Notes ...................................... 1.3 0.7 Time Deposits ......................................... 5.2 -- U.S. Government Agency Obligations--Discount Notes .... -- 0.1 U.S. Government, Agency & Instrumentality Obligations--Non-Discount Notes ..................... 12.3 16.4 Repurchase Agreements ................................. 6.2 3.1 Short-Term Securities ................................. 0.2 0.6 Liabilities in Excess of Other Assets ................. -- (0.3) Other Assets Less Liabilities ......................... 0.2 -- ----------------- Total ................................................. 100.0% 100.0% ================= * U.S. branches of foreign banks. Richard J. Mejzak Vice President and Portfolio Manager April 10, 2006 WCMA MONEY FUND MARCH 31, 2006 5 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 12b-1 fees, and other Fund expenses. The following example (which is based on a hypothetical investment of $1,000 invested on October 1, 2005 and held through March 31, 2006) 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, 2005 to October 1, 2005 March 31, 2006 March 31, 2006 ======================================================================================================================= Actual ======================================================================================================================= Class 1 $ 1,000 $1,013.70 $ 7.38 - ----------------------------------------------------------------------------------------------------------------------- Class 2 $ 1,000 $1,016.70 $ 4.42 - ----------------------------------------------------------------------------------------------------------------------- Class 3 $ 1,000 $1,018.30 $ 2.82 - ----------------------------------------------------------------------------------------------------------------------- Class 4 $ 1,000 $1,018.30 $ 2.82 ======================================================================================================================= Hypothetical (5% annual return before expenses)** ======================================================================================================================= Class 1 $ 1,000 $1,017.57 $ 7.39 - ----------------------------------------------------------------------------------------------------------------------- Class 2 $ 1,000 $1,020.51 $ 4.43 - ----------------------------------------------------------------------------------------------------------------------- Class 3 $ 1,000 $1,022.11 $ 2.82 - ----------------------------------------------------------------------------------------------------------------------- Class 4 $ 1,000 $1,022.11 $ 2.82 - ----------------------------------------------------------------------------------------------------------------------- * For each class of the Fund, expenses are equal to the annualized expense ratio for the class (1.47% for Class 1, .88% for Class 2, .56% for Class 3 and .56% for Class 4), 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 example reflects the expenses of both the feeder fund and the master trust 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. 6 WCMA MONEY FUND MARCH 31, 2006 Statement of Assets and Liabilities WCMA Money Fund As of March 31, 2006 =================================================================================================================================== Assets - ----------------------------------------------------------------------------------------------------------------------------------- Investment in Master Money Trust (the "Trust"), at value (identified cost--$7,302,111,508) ......................................... $ 7,295,826,390 Prepaid expenses and other assets .......................................... 728,399 --------------- Total assets ............................................................... 7,296,554,789 --------------- =================================================================================================================================== Liabilities - ----------------------------------------------------------------------------------------------------------------------------------- Payables: Distributor ............................................................... $ 2,022,398 Administrator ............................................................. 1,438,444 Other affiliates .......................................................... 123,000 3,583,842 --------------- Other liabilities .......................................................... 509 --------------- Total liabilities .......................................................... 3,584,351 --------------- =================================================================================================================================== Net Assets - ----------------------------------------------------------------------------------------------------------------------------------- Net assets ................................................................. $ 7,292,970,438 =============== =================================================================================================================================== Net Assets Consist of - ----------------------------------------------------------------------------------------------------------------------------------- Class 1 Shares of beneficial interest, $.10 par value, unlimited number of shares authorized ...................................................... $ 86,194,349 Class 2 Shares of beneficial interest, $.10 par value, unlimited number of shares authorized ...................................................... 254,085,883 Class 3 Shares of beneficial interest, $.10 par value, unlimited number of shares authorized ...................................................... 292,401,310 Class 4 Shares of beneficial interest, $.10 par value, unlimited number of shares authorized ...................................................... 97,244,013 Paid-in capital in excess of par ........................................... 6,569,330,001 Undistributed investment income--net ....................................... $ 104,098 Accumulated realized capital losses allocated from the Trust--net ..........

See Notes to Financial Statements. WCMA MONEY FUND MARCH 31, 2006 13 Notes to Financial Statements WCMA Money Fund 1. Significant Accounting Policies: WCMA Money 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 Money 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 interests 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, 2006 was 47.9%. The Fund is divided into multiple classes, designated Class 1, Class 2, Class 3 and Class 4. Each Class 1, Class 2, Class 3 and Class 4 Share represents interests in the same assets of the Fund and has identical voting, dividend, liquidation and other rights and the same terms and conditions, except that each class bears certain expenses related to the distribution of such shares and the incremental transfer agency costs resulting from the conversion of shares and has exclusive voting rights with respect to matters relating to such account maintenance and distribution expenditures. Income, expenses (other than expenses attributed to a specific class) and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments -- The Fund records its investments in the Trust at fair value. Valuation of securities held by the Trust is discussed in Note 1(a) 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. 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 Distribution Plans 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 account maintenance and distribution fees from the Fund. The fees are accrued daily and paid monthly at annual rates based upon the average daily net assets of the shares of the Fund as follows: - -------------------------------------------------------------------------------- Account Distribution Maintenance Fee Fee - -------------------------------------------------------------------------------- Class 1 ................................ .25% .75% Class 2 ................................ .25% .425% Class 3 ................................ .25% .125% Class 4 ................................ .25% .125% - -------------------------------------------------------------------------------- The ongoing account maintenance fee compensates MLPF&S for providing account maintenance services to shareholders. The ongoing distribution fee compensates MLPF&S for providing shareholder and distribution related services to shareholders. The Fund has entered into a contractual arrangement with FAM and MLPF&S to waive and/or reimburse a portion of the Fund's fees and expenses to ensure that the net expenses for the Fund's Class 2 Shares is .32% higher than that of CMA Money Fund, and Class 3 and Class 4 Shares is equal to that of CMA Money Fund. The fee/expense waiver or reimbursement includes account maintenance and distribution fees. This arrangement has a one-year term and is renewable. The 14 WCMA MONEY FUND MARCH 31, 2006 Notes to Financial Statements (continued) WCMA Money Fund Distributor has voluntarily agreed to waive a portion of its distribution fees in order to ensure that each class of shareholders receives a positive yield on each daily dividend. For the year ended March 31, 2006, MLPF&S earned fees of $40,756,228, of which $18,484,292 was waived. 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. Certain officers and/or trustees of the Fund are officers and/or directors of FAM, PSI, FDS, and/or ML & Co. In February 2006, ML & Co. and BlackRock, Inc. entered into an agreement to contribute ML & Co.'s investment management business, including FAM, to the investment management business of BlackRock, Inc. The transaction is expected to close in the third quarter of 2006. 3. Shares of Beneficial Interest: Net decrease in net assets derived from beneficial interest transactions was $390,953,320 and $729,160,194 for the years ended March 31, 2006 and March 31, 2005, respectively. Transactions in shares of beneficial interest for each class were as follows: - -------------------------------------------------------------------------------- Class 1 Shares for the Year Dollar Ended March 31, 2006 Shares Amount - -------------------------------------------------------------------------------- Shares sold ........................ 10,804,408,249 $ 10,804,408,249 Shares issued to shareholders in reinvestment of dividends and distributions ................ 16,738,855 16,738,855 -------------------------------------- Total issued ....................... 10,821,147,104 10,821,147,104 Shares redeemed ....................

Report of Independent Registered Public Accounting Firm WCMA Money Fund To the Shareholders and Board of Trustees of WCMA Money Fund: We have audited the accompanying statement of assets and liabilities of WCMA Money Fund as of March 31, 2006, 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 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. 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 WCMA Money Fund as of March 31, 2006, the results of its operations for the year then ended, 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.

See Notes to Financial Statements. 22 WCMA MONEY FUND MARCH 31, 2006 Notes to Financial Statements Master Money Trust 1. Significant Accounting Policies: Master Money 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 interests 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. Valuation of other short-term investment vehicles is generally based on the net asset value of the underlying investment vehicle or amortized cost. 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 value 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) Repurchase agreements -- The Trust may invest in U.S. government securities pursuant to repurchase agreements. Under such agreements, the counterparty agrees to repurchase the security at a mutually agreed upon time and price. The Trust takes possession of the underlying securities, marks-to-market such securities and, if necessary, receives additional securities daily to ensure that the contract is fully collateralized. If the counterparty defaults and the fair value of the collateral declines, liquidation of the collateral by the Trust may be delayed or limited. (c) 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. (d) Security transactions and investment income -- Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Interest income (including amortization of premium and discount) is recognized on the accrual basis. (e) Securities lending -- The Trust 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 Trust and any additional required collateral is delivered to the Trust on the next business day. Where the Trust receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Trust typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Trust receives 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 Trust may pay reasonable finder's, lending agent, administrative and custodial fees in connection with its loans. In the event that the borrower defaults on its obligation to return borrowed securities because of insolvency or for any other reason, the Trust could experience delays and costs in gaining access to the collateral. The Trust 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 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. WCMA MONEY FUND MARCH 31, 2006 23 Notes to Financial Statements (concluded) Master Money Trust 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. The Trust has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated, an affiliate of FAM, or its affiliates. Pursuant to that order, the Trust also has 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 Trust, invest cash collateral received by the Trust for such loans, among other things, in a private investment company managed by MLIM, LLC or in registered money market funds advised by Merrill Lynch Investment Managers, L.P. ("MLIM"), an affiliate of FAM. For the year ended March 31, 2006, MLIM, LLC received $25,045 in securities lending agent fees. For the year ended March 31, 2006, the Trust reimbursed FAM $335,557 for certain accounting services. Certain officers and/or trustees of the Trust are officers and/or directors of FAM, PSI, ML & Co., MLIM, and/or MLIM, LLC. In February 2006, ML & Co. and BlackRock, Inc. entered into an agreement to contribute ML & Co.'s investment management business, including FAM, to the investment management business of BlackRock, Inc. The transaction is expected to close in the third quarter of 2006. 24 WCMA MONEY FUND MARCH 31, 2006 Report of Independent Registered Public Accounting Firm Master Money Trust To the Investors and Board of Trustees of Master Money Trust: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Master Money Trust as of March 31, 2006, 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 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, 2006, 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 Money Trust as of March 31, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for the respective periods then ended, in conformity with U.S. generally accepted accounting principles.
