PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE INFORMATION. MARKET CONDITIONS Throughout the fiscal year ended July 31, 2003, economic conditions in the United States and around the world remained weak, with GDP growth averaging about 2 percent. During the first half of the fiscal year investor confidence wavered due to concerns about corporate governance and the perceived lack of balance-sheet integrity. During the second half, investor sentiment was initially dampened by geopolitical tensions leading up to the war in Iraq. Beginning in March, the market rallied sharply as investors began to discount a rebound in the global economy due to accommodative fiscal and monetary policy. Credit spreads tightened meaningfully. As a result, the markets ended the first half of calendar year 2003 with gains, the first time this has occurred since 1999. The best performing groups included cyclical sectors such as technology and consumer cyclicals and beneficiaries of looser financial conditions such as the electric power companies. PERFORMANCE ANALYSIS The Fund's underperformance is largely due to its generally conservative construction. The Fund was held back by its continued focus on high quality companies that were outpaced by more speculative companies during the period. The Fund did benefit from its exposure to healthcare, particularly medical devices and biotechnology, which are enjoying strong new product cycles. The Fund also benefited from its exposure to wireless telecommunications providers, as the leaders enjoyed gains in market share and margin improvement. 2 <Page> TOP 10 HOLDINGS <Table> Citigroup Inc. 3.1% Bank of America Corp. 2.3% Cisco Systems Inc. 2.2% Pfizer, Inc. 2.2% Wal-Mart Stores Inc. 2.2% Intel Corp. 2.0% Newmont Mining Corp. 2.0% Yahoo Inc. 1.8% Genetech Inc. 1.6% Aetna Inc. 1.5% </Table> TOP FIVE INDUSTRIES <Table> Biotechnology 6.5% Financial Conglomerates 6.2% Semiconductors 6.0% Packaged Software 4.2% Managed Health Care 3.9% </Table> SUBJECT TO CHANGE DAILY.

ORGANIZATION AND ACCOUNTING POLICIES Morgan Stanley Aggressive Equity Fund (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 capital growth. The Fund seeks to achieve its objective by primarily investing in equity securities of U.S. or foreign companies that offer the potential for superior earnings growth. The Fund was organized as a Massachusetts business trust on October 29, 1997 and commenced operations on February 24, 1999. The Fund offers Class A shares, Class B shares, Class C shares and Class D shares. The four classes are substantially the same except that most Class A shares are subject to a sales charge imposed at the time of purchase and some Class A shares, and most Class B shares and Class C shares are subject to a contingent deferred sales charge imposed on shares redeemed within one year, six years and one year, respectively. Class D shares are not subject to a sales charge. Additionally, Class A shares, Class B shares and Class C shares incur distribution expenses. The following is a summary of significant accounting policies: A. VALUATION OF INVESTMENTS -- (1) an equity portfolio security listed or traded on the New York or American Stock Exchange or other exchange is valued at its latest sale price prior to the time when assets are valued; if there were no sales that day, the security is valued at the mean between the last reported bid and asked price; (2) an equity portfolio security listed or traded on the Nasdaq is valued at the Nasdaq Official Closing Price; if there were no sales that day, the security is valued at the mean between the last reported bid and asked price; (3) all other equity portfolio securities for which over-the-counter market quotations are readily available are valued at the mean between the last reported bid and asked price. In cases where a security is traded on more than one exchange, the security is valued on the exchange designated as the primary market; (4) for equity securities traded on foreign exchanges, the last reported sale price or the latest bid price may be used if there were no sales on a particular day; (5) futures are valued at the latest price published by the commodities exchange on which they trade; (6) when market quotations are not readily available or Morgan Stanley Investment Advisors Inc. (the "Investment Manager") determines that the latest sale price, the bid price or the mean between the last reported bid and asked price do not reflect a security's market value, portfolio securities are valued at their fair value as determined in good faith under procedures established by and under the general supervision of the Fund's Trustees; (7) certain portfolio securities may be valued by an outside pricing service approved by the Fund's Trustees; and (8) short-term debt securities having a maturity date of more than sixty days at time of purchase are valued on a mark-to-market basis until sixty days prior to maturity and thereafter at amortized cost based on their value on the 61st day. Short-term debt securities having a maturity date of sixty days or less at the time of purchase are valued at amortized cost. 15 <Page> 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. Dividend income and other distributions are recorded on the ex-dividend date. Discounts are accreted and premiums are amortized over the life of the respective securities. Interest income is accrued daily. C. REPURCHASE AGREEMENTS -- Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the Fund, along with other affiliated entities managed by the Investment Manager, may transfer uninvested cash balances into one or more joint repurchase agreement accounts. These balances are invested in one or more repurchase agreements and are collateralized by cash, U.S. Treasury or federal agency obligations. The Fund may also 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. MULTIPLE CLASS ALLOCATIONS -- Investment income, expenses (other than distribution fees), and realized and unrealized gains and losses are allocated to each class of shares based upon the relative net asset value on the date such items are recognized. Distribution fees are charged directly to the respective class. E. FOREIGN CURRENCY TRANSLATION AND FORWARD FOREIGN CURRENCY CONTRACTS -- The books and records of the Fund are maintained in U.S. dollars as follows: (1) the foreign currency market value of investment securities, other assets and liabilities and forward foreign currency contracts ("forward contracts") are translated at the exchange rates prevailing at the end of the period; and (2) purchases, sales, income and expenses are translated at the exchange rates prevailing on the respective dates of such transactions. The resultant exchange gains and losses are recorded as realized and unrealized gain/loss on foreign exchange transactions. Pursuant to U.S. Federal income tax regulations, certain foreign exchange gains/losses included in realized and unrealized gain/loss are included in or are a reduction of ordinary income for federal income tax purposes. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in the market prices of the securities. Forward contracts are valued daily at the appropriate exchange rates. The resultant unrealized exchange gains and losses are recorded as unrealized foreign currency gain or loss. The Fund records realized gains or losses on delivery of the currency or at the time the forward contract is extinguished (compensated) by entering into a closing transaction prior to delivery. F. FUTURES CONTRACTS -- A futures contract is an agreement between two parties to buy and sell financial instruments or contracts based on financial indices at a set price on a future date. Upon entering into such a contract, the Fund is required to pledge to the broker cash, U.S. Government securities or other liquid portfolio securities equal to the minimum initial margin requirements of the applicable futures exchange. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments known as 16 <Page> variation margin are recorded by the Fund as unrealized gains and losses. Upon closing of the contract, the Fund realizes a gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. G. 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. H. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends and distributions to shareholders are recorded on the ex-dividend date. I. 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, the Fund pays 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: 0.75% to the portion of daily net assets not exceeding $2 billion; and 0.725% to the portion of daily net assets exceeding $2 billion. 3. PLAN OF DISTRIBUTION Shares of the Fund are distributed by Morgan Stanley Distributors Inc. (the "Distributor"), an affiliate of the Investment Manager. The Fund has adopted a Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act. The Plan provides that the Fund will pay the Distributor a fee which is accrued daily and paid monthly at the following annual rates: (i) Class A -- up to 0.25% of the average daily net assets of Class A; (ii) Class B -- 1.0% of the average daily net assets of Class B; and (iii) Class C -- up to 1.0% of the average daily net assets of Class C. In the case of Class B shares, provided that the Plan continues in effect, any cumulative expenses incurred by the Distributor but not yet recovered may be recovered through the payment of future distribution fees from the Fund pursuant to the Plan and contingent deferred sales charges paid by investors upon redemption of Class B shares. Although there is no legal obligation for the Fund to pay expenses incurred in excess of payments made to the Distributor under the Plan and the proceeds of contingent deferred sales charges paid by investors upon redemption of shares, if for any reason the Plan is terminated, the Trustees will consider at that time the manner in which to treat such expenses. The Distributor has advised the Fund that such excess amounts totaled $27,086,041 at July 31, 2003. 17 <Page> In the case of Class A shares and Class C shares, expenses incurred pursuant to the Plan in any calendar year in excess of 0.25% or 1.0% of the average daily net assets of Class A or Class C, respectively, will not be reimbursed by the Fund through payments in any subsequent year, except that expenses representing a gross sales credit to Morgan Stanley Financial Advisors or other selected broker-dealer representatives may be reimbursed in the subsequent calendar year. For the year ended July 31, 2003, the distribution fee was accrued for Class A shares and Class C shares at the annual rate of 0.25% and 1.0%, respectively. The Distributor has informed the Fund that for the year ended July 31, 2003, it received contingent deferred sales charges from certain redemptions of the Fund's Class A shares, Class B shares and Class C shares of $15, $1,158,423 and $3,429, respectively and received $29,595 in front-end sales charges from sales of the Fund's Class A shares. The respective shareholders pay such charges which are not an expense of the Fund. 4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES The cost of purchases and proceeds from sales of portfolio securities, excluding short-term investments, for the year ended July 31, 2003 aggregated $1,179,775,039 and $1,313,388,673, respectively. Included in the aforementioned are purchases and sales of U.S. Government Securities of $15,009,579 and $30,853,734, respectively and purchases and sales with other Morgan Stanley Funds $876,557 and $1,274,714, respectively including a net realized loss of $116,999. For the year ended July 31, 2003, the Fund incurred brokerage commissions of $304,240 with Morgan Stanley & Co., Inc., an affiliate of the Investment Manager and Distributor, for portfolio transactions executed on behalf of the Fund. At July 31, 2003, the Fund's receivable for investments sold included unsettled trades with Morgan Stanley & Co., Inc. of $3,806,499. Morgan Stanley Trust, an affiliate of the Investment Manager and Distributor, is the Fund's transfer agent. At July 31, 2003, the Fund had transfer agent fees and expenses payable of approximately $12,300. 5. FEDERAL INCOME TAX STATUS The amount of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations which may differ from generally accepted accounting principles. These "book/tax" differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax-basis treatment; temporary 18 <Page> differences do not require reclassification. Dividends and distributions which exceed net investment income and net realized capital gains for tax purposes are reported as distributions of paid-in-capital. As of July 31, 2003, the tax-basis components of accumulated losses were as follows: <Table> Net accumulated earnings -- Capital loss carryforward* $ (487,082,590) Post-October losses (21,746,710) Net unrealized appreciation 37,129,138 -------------- Total accumulated losses $ (471,700,162) ============== </Table> *As of July 31, 2003, the Fund had a net capital loss carryforward of $487,082,590 of which $366,027,253 will expire on July 31, 2010 and $121,055,337 will expire on July 31, 2011 to offset future capital gains to the extent provided by regulations. As of July 31, 2003, the Fund had temporary book/tax differences primarily attributable to post-October losses (capital losses incurred after October 31 within the taxable year which are deemed to arise on the first business day of the Fund's next taxable year) and capital loss deferrals on wash sales and permanent book/tax differences primarily attributable to a net operating loss. To reflect reclassifications arising from the permanent differences, paid-in-capital was charged $4,980,373, accumulated net investment loss was credited $4,980,174 and accumulated net realized loss was credited $199. 6. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS The Fund may enter into forward contracts to facilitate settlement of foreign currency denominated portfolio transactions or to manage foreign currency exposure associated with foreign currency denominated securities. To hedge against adverse interest rate, foreign currency and market risks, the Fund may purchase and sell interest rate, currency and index futures ("futures contracts"). Forward contracts and futures contracts involve elements of market risk in excess of the amount reflected in the Statement of Assets and Liabilities. The Fund bears the risk of an unfavorable change in the foreign exchange rates underlying the forward contracts. Risks may also rise upon entering into these contracts from the potential inability of the counterparties to meet the terms of their contracts. At July 31, 2003, the Fund had outstanding forward and futures contracts. 19 <Page> 7.

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 audits. We conducted our audits 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 July 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 audits provide 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 Morgan Stanley Aggressive Equity Fund as of July 31, 2003, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America.
