After one of the most significant equity market downturns in many investors' memories, this year finally brought hopeful signs for a sustainable economic recovery. Sub par economic growth of 1.4% in the first quarter of 2003 increased to projected growth of more than 4% in the second half of the year. With that good news, fixed income investments, which had become the asset class of choice during the long equity market decline, faced new challenges. Earlier in the year, the Federal Reserve Board continued its accommodative monetary policy, lowering the Federal Funds rate in June to 1%, its lowest level since 1958. With this move, long-term interest rates continued to be volatile, as investors began to anticipate the impact of future Federal Reserve Board moves and economic revitalization. As of September 30, 2003, the ten-year Treasury bond was yielding 3.96%. This compared to a yield of 3.83% six months earlier and 3.63% one year ago. Against this backdrop, our portfolio managers continued to work diligently to deliver on our commitment to provide superior performance within reasonable expectations for risk and return. With that said, remember also that the advice and guidance of a skilled financial advisor often can mean the difference between successful and unsuccessful investing. A financial professional can help you choose those investments that will best serve you as you plan for your financial future. Finally, I am proud to premiere a new look to our shareholder communications. Our portfolio manager commentaries have been trimmed and organized in such a way that you can get the information you need at a glance, in plain language. Today's markets are confusing enough. We want to help you put it all in perspective. The report's new size also allows us certain mailing efficiencies. Any cost savings in production or postage are passed on to the Fund and, ultimately, to Fund shareholders. 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, /s/ Terry K. Glenn Terry K. Glenn President and Trustee WCMA GOVERNMENT SECURITIES FUND SEPTEMBER 30, 2003 3 [LOGO] Merrill Lynch Investment Managers A Discussion With Your Fund's Portfolio Manager We took advantage of declining interest rates during the period by increasing our holdings in the longer end of the yield curve. How did the Fund perform during the period in light of the existing market conditions? For the six-month period ended September 30, 2003, WCMA Government Securities Fund's Class 1, Class 2, Class 3 and Class 4 Shares paid shareholders net annualized dividends of .69%, .71%, .79% and .79%, respectively.* As of September 30, 2003, the Fund's Class 1, Class 2, Class 3 and Class 4 Shares had seven-day yields of .07%, .15%, .47% and .47%, respectively. The average portfolio maturity for the Fund at September 30, 2003 was 64 days, compared to 60 days at March 31, 2003. Fund positioning during the period hinged largely on the shape of the yield curve. The Federal Reserve Board maintained its accommodative monetary policy throughout the period, cutting the Federal Funds rate to 1% in June, its lowest level since 1958. As short-term interest rates declined, we extended out on the yield curve to take advantage of longer-dated securities with higher yields. Although we were confident that the Federal Reserve Board would leave interest rates at their current level for some time, we were aware that market conditions, such as a change in the dismal employment picture, could force rates to rise. As a result, throughout the period, we readjusted the Fund's average life, extending it when interest rates rose and reducing average life when we believed interest rates had bottomed. Adding to the general market and economic dynamics during the period were supply factors. At the beginning of the period, the U.S. Treasury was issuing more front-end Treasury bills and Treasury notes than ever before to cover a growing deficit. This, and the reintroduction of the three-year Treasury note in the refunding cycle, led to a steeper yield curve, with higher yields on the longer end of the curve. How did you manage the Fund during the period? We focused on the fulcrum point of the curve and remained cognizant of where interest rates were with respect to financing levels. Ultimately, the sector of choice became the 12-month - 15-month area of the curve. While we expected interest rates would remain stable for the near term, we were encouraged to increase our holdings in repurchase agreements modestly, which allowed us to extend on the yield curve. The Fund's average life throughout the period was a good indicator of how we felt about the market. Our lowest average life occurred during the latter part of May through early June when the spread between three-month Treasury bills and two-year Treasury notes narrowed to 18 basis points (.18%). As interest rates rose in August and the curve grew steeper, we extended the portfolio's average life out to the 70-day range by adding 13-month - 14-month bills. Our sentiment at this time was that the market was overdone on the upside. In the front end, we added some Treasury bills in the six-month area as the yields on these securities became positive to financing levels. By the end of September, we started to bring the Fund's average life in as we saw the yield curve begin to flatten, which gave us less enthusiasm for going further out on the curve. * Based on a constant investment throughout the period, with dividends compounded daily, and reflecting a net return to the investor after all expenses. 4 WCMA GOVERNMENT SECURITIES FUND SEPTEMBER 30, 2003 How would you characterize the Fund's position at the close of the period? We believe the Fund is well positioned going forward. As the period closed, we remained focused on the 13-month - 14-month sector for yield enhancement and price appreciation. We plan to maintain a longer average life, as the Federal Reserve Board has stated it will be slow to increase interest rates to ensure the economy's recovery. Our high liquidity base offers us opportunities to become more involved if interest rates move higher. Recent gains in employment are starting to materialize and other economic statistics have suggested a more broad-based recovery. The majority of our interest rate exposure currently is in the 12-month - 15-month sector. This area has been the pivotal point of the yield curve, which has allowed us to "roll down" the yield curve and extend at higher levels as opportunities present themselves. As the two-year sector approaches 1.75% - 2%, we may add some positions in that area as well.

See Notes to Financial Statements. 10 WCMA GOVERNMENT SECURITIES FUND SEPTEMBER 30, 2003 Notes to Financial Statements WCMA Government Securities Fund 1. Significant Accounting Policies: WCMA Government Securities 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 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. These unaudited financial statements reflect all adjustments, which are, in the opinion of management, necessary to a fair statement of the results for the interim period presented. All such adjustments are of a normal, recurring nature. The percentage of the Fund owned by the Trust at September 30, 2003 was 43.5%. The Fund is divided into four 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 have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that each class bears certain expenses related to account maintenance and the distribution of such shares and the additional incremental transfer agency costs resulting from the conversion of shares and have 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 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 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"), 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 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 respective shareholders. The ongoing distribution fee compensates MLPF&S for providing shareholder and distribution-related WCMA GOVERNMENT SECURITIES FUND SEPTEMBER 30, 2003 11 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements (concluded) WCMA Government Securities Fund services to respective shareholders. FAM and MLPF&S have entered into a contractual arrangement 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 Government Securities Fund, and Class 3 and Class 4 Shares is equal to that of CMA Government Securities Fund. The fee/expense waiver or reimbursement includes account maintenance and distribution fees. This arrangement has a one-year term, which began on the commencement date of operations and is renewable. The Distributor has voluntarily agreed to waive a portion of its distribution fees in order to ensure that each class of shareholders receive a positive yield on each daily dividend. For the six months ended September 30, 2003, MLPF&S has earned fees of $331,832, of which $202,548 was waived. 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. Beneficial Interest Transactions: Net increase in net assets derived from beneficial interest transactions was $584,134,358 and $74 for the six months ended September 30, 2003 and for the period March 3, 2003 to March 31, 2003, respectively.

Significant Accounting Policies: Master Government Securities 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 accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. These unaudited financial statements reflect all adjustments, which are, in the opinion of management, necessary to a fair statement of the results for the interim period presented. All such adjustments are of a normal, recurring nature. 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. 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. 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 six months ended September 30, 2003, the Trust reimbursed FAM $14,731 for certain accounting services. Certain officers and/or trustees of the Trust are officers and/or directors of FAM, PSI, and/or ML & Co.
