WCMA Money Fund
Notes to Financial Statements

1. Significant Accounting Policies:

WCMA Money Fund (the "Fund") is registered under the Investment Company Act of
1940 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 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 accounting principles generally accepted in the United States of America,
which may require the use of management accruals and estimates. The Fund
commenced operations on March 3, 2003 when it contributed its initial seed
capital to the Trust. The effective date of the Fund's registration with the
Securities and Exchange Commission was March 20, 2003. Prior to March 3, 2003,
the Fund had no operations other than those relating to organizational matters
and the issuance of 100,000 shares of beneficial interest of the Fund to Fund
Asset Management, L.P. ("FAM") for $100,000. The percentage of the Trust owned
by the Fund at March 31, 2003 was less than 0.1%. The Fund offers four classes,
designated Class 1, Class 2, Class 3 and Class 4. All classes of shares have
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. Each class has exclusive voting rights with respect
to matters relating to such distribution expenditures. Income, expenses (other
than expenses attributed to a specific class) and realized and unrealized gains
and losses on investments 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 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 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 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"), a subsidiary of ML & Co., 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
                                               Maintenance          Distribution
                                               Fee                  Fee
- --------------------------------------------------------------------------------
Class 1...................................     .25%                 .75%
Class 2...................................     .25%                 .43%
Class 3...................................     .25%                 .125%
Class 4...................................     .25%                 .125%
- --------------------------------------------------------------------------------

The ongoing account maintenance fee compensates MLPF&S for providing account
maintenance services to Class 1, Class 2, Class 3 and Class 4 shareholders. The
ongoing distribution fee compensates MLPF&S for providing shareholder and
distribution-related services to shareholders. For the period ended March 31,
2003, MLPF&S has waived the Fund's account maintenance and distribution fees.

Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co., is
the Fund's transfer agent.

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 reinvested during the period corresponds to the amount
included in the Statement of Changes in Net Assets for value of shares
reinvested since shares are recorded at $1.00 per share.

INDEPENDENT AUDITORS' REPORT

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, 2003, and the related statements of operations and
changes in net assets for the period March 3, 2003 (commencement of operations)
through March 31, 2003, and the financial highlights for the period March 20,
2003 through March 31, 2003. 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 audit.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America. 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. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides 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, 2003, the results of its operations and the changes
in its net assets for the period March 3, 2003 through March 31, 2003, and its

MASTER MONEY TRUST
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. Significant Accounting Policies:

Master Money Trust (the "Trust") is registered under the Investment Company Act
of 1940 and is organized as a Delaware business trust. The Declaration of Trust
permits the Trustees to issue nontransferable interest in the Trust, subject to
certain limitations. On February 13, 2003, the Trust received all of the assets
of CMA Money Fund, a registered investment company that converted to a
master/feeder structure. The Trust's financial statements are prepared in
conformity with accounting principles generally accepted in the United States of
America, which may require the use of management accruals and estimates. The
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 purpose 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 for which market value quotations are not available
are valued at their fair value as determined in good faith by or under the
direction of the Trust's Board of Trustees.

(b) Repurchase agreements -- The Trust invests 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. Accordingly, as a "pass through"
entity, the Trust pays no income dividends or capital gains distributions.
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

MASTER MONEY TRUST
NOTES TO FINANCIAL STATEMENTS (CONCLUDED)
- --------------------------------------------------------------------------------

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.

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 ("MLPF&S"), or its affiliates. As of March 31, 2003,
the Trust lent securities with a value of $45,017,550 to MLPF&S 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

a reverse repurchase agreement, it will establish a segregated account with the
custodian containing cash, cash equivalents or liquid high grade debt securities
having a value at least equal to the repurchase price.

The Trust had no reverse repurchase agreements outstanding during the period
ended March 31, 2003.

MASTER MONEY TRUST
INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------

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, 2003, and the
related statements of operations and changes in net assets, and the financial
highlights for the period February 13, 2003 (commencement of operations) through
March 31, 2003. 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
audit.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America. 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. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of March 31, 2003, by correspondence with the custodian and
brokers. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides 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, 2003, the results of its operations, the changes in
its net assets, and its financial highlights for the period February 13, 2003
through March 31, 2003, in conformity with accounting principles generally
accepted in the United States of America.
