FUND REPORT For the six-month period ended December 31, 2003 MARKET CONDITIONS The Federal Open Market Committee (the "Fed") lowered its target rate for federal funds to 1.00 percent, a 45-year low, on June 25, 2003. It maintained that target throughout the second half of the year to encourage a faster pace of economic activity. By the second half of 2003 the combination of this highly accommodative monetary posture and stimulative fiscal policies in the form of tax cuts appeared to begin to have an effect, with many companies reporting improved second-half earnings and the third-quarter GDP increasing to 8.2 percent. The Fed's sustained emphasis on low interest rates had a marked impact on money market fund yields, which reached record low levels during the period. PERFORMANCE ANALYSIS As of December 31, 2003, Active Assets Government Securities Trust had net assets of approximately $1.22 billion and the average maturity of the Fund's portfolio was 42 days. For the six-month period ended December 31, 2003, the Fund returned 0.25 percent. For the seven-day period ended December 31, 2003, the Fund provided an effective annualized yield and a current yield both of 0.50 percent, while its 30-day moving average yield for December was 0.51 percent. Past performance is no guarantee of future results. Our strategy in managing the Fund remained consistent with our long-term focus on maintaining preservation of capital and very high liquidity.* As we have in the past, we adhered to a conservative approach that avoided the use of derivatives or structured notes that might fluctuate excessively with changing interest rates. On December 31, 2003, approximately 96 percent of the Fund's portfolio was invested in federal agency discount notes with the remaining 4 percent in a U.S. Treasury obligation. At the end of the fiscal period, approximately 96 percent of the Fund's holdings were due to mature in less than four months. - ---------------------------------------------------- * An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund. 2 <Table> <Caption> PORTFOLIO COMPOSITION U.S. Government Agencies 95.9% U.S. Treasury Bill 4.1 </Table> <Table> <Caption> MATURITY SCHEDULE 1 - 30 Days 43.6% 31 - 60 Days 31.9 61 - 90 Days 14.7 91 - 120 Days 5.7 121+ Days 4.1 </Table> Subject to change daily.

Organization and Accounting Policies Active Assets Government Securities Trust (the "Fund") is registered under the Investment Company Act of 1940, as amended (the "Act"), as a diversified, open-end management investment company. The Fund's investment objectives are high current income, preservation of capital and liquidity. The Fund was organized as a Massachusetts business trust on March 30, 1981 and commenced operations on July 7, 1981. The following is a summary of significant accounting policies: A. Valuation of Investments -- Portfolio securities are valued at amortized cost, which approximates market value. B. Accounting for Investments -- Security transactions are accounted for on the trade date (date the order to buy or sell is executed). Realized gains and losses on security transactions are determined by the identified cost method. Discounts are accreted and premiums are amortized over the life of the respective securities. Interest income is accrued daily. C. Repurchase Agreements -- The Fund may invest directly with institutions in repurchase agreements. The Fund's custodian receives the collateral, which is marked-to-market daily to determine that the value of the collateral does not decrease below the repurchase price plus accrued interest. D. Federal Income Tax Policy -- 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. Accordingly, no federal income tax provision is required. E. Dividends and Distributions to Shareholders -- The Fund records dividends and distributions to shareholders as of the close of each business day. F. Use of Estimates -- The preparation of financial statements in accordance with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts and disclosures. Actual results could differ from those estimates. 2. Investment Management Agreement Pursuant to an Investment Management Agreement with Morgan Stanley Investment Advisors Inc. (the "Investment Manager"), the Fund pays the Investment Manager a management fee, accrued daily and payable monthly, by applying the following annual rates to the net assets of the Fund determined as of the close of each business day: 0.50% to the portion of daily net assets not exceeding 8 Active Assets Government Securities Trust NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 2003 (UNAUDITED) continued $500 million; 0.425% to the portion of daily net assets exceeding $500 million but not exceeding $750 million; 0.375% to the portion of daily net assets exceeding $750 million but not exceeding $1 billion; 0.35% to the portion of daily net assets exceeding $1 billion but not exceeding $1.5 billion; 0.325% to the portion of daily net assets exceeding $1.5 billion but not exceeding $2 billion; 0.30% to the portion of daily net assets exceeding $2 billion but not exceeding $2.5 billion; 0.275% to the portion of daily net assets exceeding $2.5 billion but not exceeding $3 billion; and 0.25% to the portion of daily net assets exceeding $3 billion. 3. Plan of Distribution Morgan Stanley Distributors Inc. (the "Distributor"), an affiliate of the Investment Manager, is the distributor of the Fund's shares and in accordance with a Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act, finances certain expenses in connection with the promotion of sales of Fund shares. Reimbursements for these expenses are made in monthly payments by the Fund to the Distributor, which will in no event exceed an amount equal to a payment at the annual rate of 0.15% of the Fund's average daily net assets during the month. Expenses incurred by the Distributor pursuant to the Plan in any fiscal year will not be reimbursed by the Fund through payments accrued in any subsequent fiscal year. For the six months ended December 31, 2003, the distribution fee was accrued at the annual rate of 0.10%. 4. Security Transactions and Transactions with Affiliates The cost of purchases and proceeds from sales/maturities of portfolio securities for the six months ended December 31, 2003, aggregated $20,007,143,517 and $20,022,453,677, respectively. Morgan Stanley Trust, an affiliate of the Investment Manager and Distributor, is the Fund's transfer agent. At December 31, 2003, the Fund had transfer agent fees and expenses payable of approximately $1,300. The Fund has an unfunded noncontributory defined benefit pension plan covering certain independent Trustees of the Fund who will have served as independent Trustees for at least five years at the time of retirement. Benefits under this plan are based on factors which include years of service and compensation. Aggregate pension costs for the six months ended December 31, 2003, included in Trustees' fees and expenses in the Statement of Operations amounted to $3,674. At December 31, 2003, the Fund had an accrued pension liability of $60,304 which is included in accrued expenses in the Statement of Assets and Liabilities. 9 Active Assets Government Securities Trust NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 2003 (UNAUDITED) continued On December 2, 2003, the Trustees voted to close the plan to new participants, eliminate the future benefits growth due to increases to compensation after July 31, 2003 and effective April 1, 2004, establish an unfunded deferred compensation plan which allows each independent Trustee to defer payment of all or a portion of the fees he receives for serving on the Board of Trustees throughout the year. 5. Shares of Beneficial Interest Transactions in shares of beneficial interest, at $1.00 per share, were as follows: <Table> <Caption> FOR THE SIX FOR THE YEAR MONTHS ENDED ENDED DECEMBER 31, 2003 JUNE 30, 2003 ----------------- -------------- (unaudited) Shares sold................................................. 3,180,778,452 6,396,600,275 Shares issued in reinvestment of dividends and distributions............................................. 3,291,368 13,784,355 -------------- -------------- 3,184,069,820 6,410,384,630 Shares redeemed.............................................

Legal Matters The Investment Manager, certain affiliates of the Investment Manager and certain investment companies advised by the Investment Manager or its affiliates, including the Fund, are named as defendants in a number of recently filed, similar class action complaints. These complaints generally allege that defendants, including the Fund, violated their statutory disclosure obligations and fiduciary duties by failing properly to disclose (i) that the Investment Manager and certain affiliates of the Investment Manager allegedly offered economic incentives to brokers and others to steer investors to the funds advised by the Investment Manager or its affiliates rather than funds managed by other companies, and (ii) that the funds advised by the Investment Manager or its affiliates, including the Fund, allegedly paid excessive commissions to brokers in return for their alleged efforts to steer investors to these funds. The complaints seek, among other things, unspecified compensatory damages, rescissionary damages, fees and costs. The defendants intend to move to dismiss these actions and otherwise vigorously to defend them. While the Fund believes that it has meritorious defenses, the ultimate outcome of these matters is not presently determinable at this early stage of the litigation, and no provision has been made in the Fund's financial statements for the effect, if any, of these matters. 10 Active Assets Government Securities Trust FINANCIAL HIGHLIGHTS Selected ratios and per share data for a share of beneficial interest outstanding throughout each period: <Table> <Caption> FOR THE SIX FOR THE YEAR ENDED JUNE 30, MONTHS ENDED --------------------------------------------------------------- DECEMBER 31, 2003 2003 2002 2001 2000 1999 ----------------- ----------- ----------- ----------- --------- --------- (unaudited) Selected Per Share Data: Net asset value, beginning of period.......................... $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 ------- ------- ------- ------- ------ ------ Net income from investment operations...................... 0.003 0.009 0.020 0.053 0.050 0.045 Less dividends from net investment income...............
