Report to Stockholders. Morgan Stanley Limited Duration Fund LETTER TO THE SHAREHOLDERS / / APRIL 30, 2003 Dear Shareholder: This annual report to shareholders of Morgan Stanley Limited Duration Fund covers the 12-month period ended April 30, 2003. The period included a continuation of the persistent concerns that have resulted in investment-grade securities yields falling to 45-year lows. These included concerns about corporate accounting and governance, the conflict in the Mideast, potential terrorist events and SARS. By the beginning of the period, the cumulative effects of corporate-governance and accounting scandals had shaken investor confidence, with adverse effects on the economy and the non-government security markets. The deterioration in confidence was especially pronounced following the first announcement in late June of accounting fraud at WorldCom. The resulting flight to quality and subsequent additional easing of monetary policy created a fresh impetus toward lower Treasury yields. Thereafter, there were several periods in which market participants began to believe that the economy was improving and security yields rose. Each of these was followed by renewed concerns about the geopolitical situation and, toward the end of the period, about SARS. Interest rates fell relatively sharply during the first half of the review period, then posted more-moderate changes during the latter half. For example, during the first half the two-year Treasury yield fell from 3.22 percent to 1.67 percent. During the latter half it fell an additional 18 basis points to 1.49 percent. In our view, these low yields were inconsistent with an eventual return to normal economic activity. Our analysis suggests that, by the end of the period, Treasury yields were consistent with slow economic growth for about the next five years and below full employment growth for some ten years. We viewed the market's implied outlook as being excessively pessimistic. Accordingly, we reduced the Fund's interest-rate sensitivity to lessen the effect if interest rates rose. Although this decision hampered the Fund's performance somewhat, it left the Fund with some insulation from potentially rising rates during the period ahead. Performance For the 12-month period ended April 30, 2003, the Fund produced a total return of 3.93 percent versus 10.45 percent for the Lehman Brothers U.S. Credit Index (1-5 Year) and 4.79 percent for the Lipper Short Investment Grade Bond Funds Index. THE TOTAL RETURN FIGURES ASSUME THE REINVESTMENT OF ALL DISTRIBUTIONS. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. The Fund's performance relative to its benchmark was handicapped by its relatively limited duration. Throughout the period, the Fund maintained a duration that was well below that of the Lehman Index, because of the manager's view that interest rates reflected an overly pessimistic outlook for the economy. The Fund's effective duration averaged approximately one year throughout the review period and stood at 0.88 years on April 30, 2003, compared to 2.75 years for the Lehman Index. <Page> Morgan Stanley Limited Duration Fund LETTER TO THE SHAREHOLDERS / / APRIL 30, 2003 CONTINUED In addition, a relatively large portion of the Fund was invested in higher-coupon mortgage-backed securities. This sector lagged others during the period because of concerns that falling interest rates would result in a sustained period of high mortgage prepayment speeds. We appreciate your ongoing support of Morgan Stanley Limited Duration Fund and look forward to continuing to serve your investment needs. Very truly yours, [/S/ CHARLES A.

Organization and Accounting Policies Morgan Stanley Limited Duration Fund (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a diversified, open-end management investment company. The Fund's investment objective is to provide a high level of current income consistent with the preservation of capital. The Fund seeks to achieve its objective by investing in a diversified portfolio of short-term fixed income securities. The Fund was organized as a Massachusetts business trust on October 22, 1993 and commenced operations on January 10, 1994. The following is a summary of significant accounting practices: A. Valuation of Investments -- (1) 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; (2) futures are valued at the latest price published by the commodities exchange on which they trade; (3) when market quotations are not readily available or Morgan Stanley Investment Advisors Inc. (the "Investment Manager") determines that the market quotations are not reflective of 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; (4) certain portfolio securities may be valued by an outside pricing service approved by the Fund's Trustees; and (5) 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. 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 -- 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. 15 <Page> Morgan Stanley Limited Duration Fund NOTES TO FINANCIAL STATEMENTS / / APRIL 30, 2003 CONTINUED D. 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 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. E. 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. F. Dividends and Distributions to Shareholders -- Dividends and distributions to shareholders are recorded on the ex-dividend date. 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. 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 0.70% to the net assets of the Fund determined as of the close of each business day. For the period May 1, 2002 through December 31, 2002, the Investment Manager waived its fee and reimbursed expenses to the extent they exceeded 0.80% of the daily net assets of the Fund. 3. Security Transactions and Transactions with Affiliates The cost of purchases and proceeds from sales/prepayments of portfolio securities, excluding short-term investments, for the year ended April 30, 2003 were $695,123,814, and $542,744,348, respectively. Included in the aforementioned are purchases and sales/prepayments of U.S. Government securities of $624,655,282 and $516,102,538, respectively. 16 <Page> Morgan Stanley Limited Duration Fund NOTES TO FINANCIAL STATEMENTS / / APRIL 30, 2003 CONTINUED Morgan Stanley Trust, an affiliate of the Investment Manager, is the Fund's transfer agent. At April 30, 2003, the Fund had transfer agent fees and expenses payable of approximately $2,600. 4.

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 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. The tax character of distributions paid was as follows: <Table> <Caption> FOR THE YEAR FOR THE YEAR ENDED ENDED APRIL 30, 2003 APRIL 30, 2002 -------------- -------------- Ordinary Income......................... $8,187,421 $6,198,203 </Table> 17 <Page> Morgan Stanley Limited Duration Fund NOTES TO FINANCIAL STATEMENTS / / APRIL 30, 2003 CONTINUED As of April 30, 2003, the tax-basis components of accumulated losses were as follows: <Table> Undistributed ordinary income..................... $ 631,448 Undistributed long-term gains..................... -- ---------- Net accumulated earnings.......................... 631,448 Capital loss carryforward*........................

As part of the Fund's acquisition of the assets of Morgan Stanley North American Government Income Trust ("North American"), the Fund obtained a net capital loss carryforward of approximately $18,769,000 from North American. Utilization of this carryforward is subject to limitations imposed by the Internal Revenue Code and Treasury Regulations, reducing the total carryforward available. As of April 30, 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 book amortization of premiums on debt securities and permanent book/tax differences attributable to losses on paydowns, tax adjustments on debt securities sold by the Fund and an expired capital loss carryforward. To reflect reclassifications arising from the permanent differences, paid-in-capital was charged $14,716,492, dividends in excess of net investment income was credited $2,000,374 and accumulated net realized loss was credited $12,716,118. 6. Purposes of and Risks Relating to Certain Financial Instruments To hedge against adverse interest rate and market risks on portfolio positions or anticipated positions in U.S. Government securities, the Fund may enter into interest rate futures contracts ("futures contracts"). These futures contracts involve elements of market risk in excess of the amount reflected in the Statement and Assets and Liabilities. The Fund bears the risk of an unfavorable change in the value of the underlying securities. At April 30, 2003, the Fund had outstanding interest rate future contracts. 18 <Page> Morgan Stanley Limited Duration Fund NOTES TO FINANCIAL STATEMENTS / / APRIL 30, 2003 CONTINUED 7. Acquisition of Morgan Stanley North American Government Income Trust On November 4, 2002, the Fund acquired all the net assets of the Morgan Stanley North American Government Income Trust ("North American") based on the respective valuations as of the close of business on November 1, 2002, pursuant to a plan of reorganization approved by the shareholders of North American on October 23, 2002. The acquisition was accomplished by a tax-free exchange of 7,879,235 shares of the Fund at a net asset value of $9.68 per share for 8,837,891 shares of North American. The net assets of the Fund and North American immediately before the acquisition were $273,925,042 and $76,281,762, respectively, including unrealized appreciation of $982,393 for North American.

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 April 30, 2003, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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 Limited Duration Fund as of April 30, 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 five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.
