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 the year 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 Institutional Government Securities Trust had net assets of more than $263 million and the average maturity of the Fund's portfolio was 36 days. For the six-month period ended December 31, 2003, the Fund returned 0.49 percent. For the seven-day period ended December 31, 2003, the Fund provided an effective annualized yield and a current yield both of 0.95 percent, while its 30-day moving average yield for December was 0.98 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 always, 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 80 percent of the Fund's portfolio was invested in federal agency obligations, 6 percent in U.S. Treasury obligations and the remaining 14 percent in an overnight repurchase agreement. At the end of the fiscal period, approximately 97 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.

Organization and Accounting Policies Active Assets Institutional Government 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 objective is high current income, preservation of capital and liquidity. The Fund was organized as a Massachusetts business trust on January 18, 2002 and had no operations other than those relating to organizational matters and the issuance of 100,000 shares of beneficial interest for $100,000 to Morgan Stanley Investment Advisors Inc. (the "Investment Manager") to effect the Fund's initial capitalization. The Fund commenced operations on November 4, 2002. 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. Offering Costs -- The Investment Manager incurred offering costs on behalf of the Fund in the amount of $73,790, which have been reimbursed by the Fund for the full amount thereof, exclusive of amounts waived. Such expenses have been deferred and were fully amortized as of November 3, 2003. G. 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. 8 Active Assets Institutional Government Securities Trust NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 2003 (UNAUDITED) continued 2. Investment Management Agreement Pursuant to an Investment Management Agreement, the Fund pays the Investment Manager a management fee, accrued daily and payable monthly, by applying the annual rate of 0.15% to the net assets of the Fund determined as of the close of each business day. The Investment Manager has agreed to reimburse all operating expenses and to waive the compensation provided for in its Investment Management Agreement until December 31, 2004, to the extent that such expenses and compensation on an annualized basis exceed the following net asset levels: 0.05% of the Fund's daily net assets up to $250 million; 0.10% of the Fund's daily net assets while the Fund's net assets are between $250 million and $500 million; 0.15% of the Fund's daily net assets while the Fund's net assets are between $500 million and $750 million; and 0.20% of the Fund's daily net assets once the Fund's net assets exceed $750 million. At December 31, 2003, included in the Statement of Assets and Liabilities is a receivable from affiliate, which represents expense reimbursements due to the Fund. 3. 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 $8,398,447,985 and $8,291,100,101, respectively. Morgan Stanley Trust, an affiliate of the Investment Manager, is the Fund's transfer agent. 4. Shares of Beneficial Interest Transactions in shares of beneficial interest, at $1.00 per share, were as follows: <Table> <Caption> FOR THE PERIOD FOR THE SIX NOVEMBER 4, 2002* MONTHS ENDED THROUGH DECEMBER 31, 2003 JUNE 30, 2003 ----------------- ----------------- (unaudited) Shares sold................................................. 731,851,779 357,206,297 Shares issued in reinvestment of dividends.................. 1,107,366 429,497 -------------- ------------ 732,959,145 357,635,794 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 Institutional 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 PERIOD FOR THE SIX NOVEMBER 4, 2002* MONTHS ENDED THROUGH DECEMBER 31, 2003 JUNE 30, 2003 ----------------- ----------------- (unaudited) Selected Per Share Data: Net asset value, beginning of period........................ $ 1.00 $ 1.00 ------ ------ Net income from investment operations....................... 0.005 0.008 Less dividends from net investment income...................
