WCMA Government Securities Fund
Notes to Financial Statements

1. Significant Accounting Policies:

WCMA Government Securities 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 Government Securities 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.


                                       2


(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 Government Securities Fund:

We have audited the accompanying statement of assets and liabilities of WCMA
Government Securities 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
Government Securities 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 financial highlights for the period March 20, 2003 through March

MASTER GOVERNMENT SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. Significant Accounting Policies:

Master Government Securities 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 Government Securities 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 the 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.

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.

MASTER GOVERNMENT SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS (CONCLUDED)
- --------------------------------------------------------------------------------

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, 2003, the Fund reimbursed FAM $4,718 for certain
accounting services.

Certain officers and/or trustees of the Trust are officers and/or directors of
FAM, PSI, and/or ML & Co.

MASTER GOVERNMENT SECURITIES TRUST
INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------

To the Investors and Board of Trustees of
Master Government Securities Trust:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Master Government Securities 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
Government Securities 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.
