SUCH COSTS WOULD LOWER PERFORMANCE. SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE AND BENCHMARK INFORMATION. MARKET CONDITIONS The reporting period opened on a positive note following a string of strong economic data. Investor sentiment reflected anticipation that the Federal Open Market Committee (the Fed) would raise interest rates. This indeed proved to be the case. Beginning in June, the Fed began a series of increases to the federal funds rate, which brought the rate to 2.75 percent at the close of the reporting period. Continued softness in the economy pushed yields on intermediate and longer-maturity securities lower in the third and into the fourth quarter of 2004. The market's concerns were fueled by continued weakness in employment growth, anxiety about the U.S trade deficit and budget deficit, steady rises in oil prices and uncertainty over the outcome of the U.S. presidential election. The climate changed in November, however, when a surprisingly strong increase in non-farm payrolls and in producer and consumer price indices pushed rates higher. This improved sentiment continued well into the first quarter of 2005 as rates continued to rise. Against this backdrop, the yield curve flattened overall. Short- and intermediate-term yields rose across the U.S. Treasury curve, while longer term (10 years and longer) yields declined. Performance among U.S. government and mortgage sectors varied during the period. Treasuries and agencies posted the least impressive performance among the major fixed-income sectors, due to their relative lack of yield and greater sensitivity to changes in interest rates. Higher coupon mortgage-backed securities, which tend to be less sensitive to rising interest rates, outperformed their lower-coupon peers during the period. Generally, corporate issues performed well due to investors' desire for higher-yielding securities. Nevertheless, corporate yield spreads widened during the first four months of 2005, most notably within the auto sector. General Motors' (GM) lowered earnings guidance for the balance of 2005 took a toll on its bonds, and also cast a shadow across the auto and auto-related industry. 2 <Page> PERFORMANCE ANALYSIS Morgan Stanley Limited Duration Fund underperformed both the Lehman Brothers 1-5 Year U.S. Credit Index and the Lipper Short Investment Grade Debt Funds Index for the 12 months ended April 30, 2005. Within the government sector, performance was varied. The Fund's emphasis on higher-coupon, slow-prepaying mortgage issues benefited the Fund as rates rose during the bulk of the period. Because of this focus, the Fund was less susceptible to market volatility. However, an underweight to the agency sector detracted slightly from relative performance as spreads tightened. Additionally, the Fund's U.S. Treasuries generated more muted performance due to their relative lack of yield. Within the corporate debt sector, the Fund gained from its emphasis on insurance companies, which outperformed for the period. Strong security selection in the energy sector further enhanced returns. Additionally, a benchmark-neutral weighting in the auto sector benefited relative performance in 2005. On the upside, the portfolio's exposure to medium-quality issues benefited relative performance during the majority of the period. Overall, paper, gaming and lodging, and energy credits remain the emphasis of the portfolio's medium-quality corporate holdings. Within the high-quality segment, our sole overweight relative to the benchmark is in the insurance area. Throughout the reporting period, we managed the Fund's overall duration*, or interest-rate sensitivity, to be in line with ("neutral") or below that of its benchmark. The defensive, below-benchmark duration was beneficial as interest rates rose across the short and intermediate-portions of the curve. The neutral position benefited relative performance during periods when rates declined. * A MEASURE OF THE SENSITIVITY OF A BOND'S PRICE TO CHANGES IN INTEREST RATES, EXPRESSED IN YEARS. EACH YEAR OF DURATION REPRESENTS AN EXPECTED 1 PERCENT CHANGE IN THE PRICE OF A BOND FOR EVERY 1 PERCENT CHANGE IN INTEREST RATES. THE LONGER A BOND'S DURATION, THE GREATER THE EFFECT OF INTEREST-RATE MOVEMENTS ON ITS PRICE. TYPICALLY, FUNDS WITH SHORTER DURATIONS PERFORM BETTER IN RISING-INTEREST-RATE ENVIRONMENTS, WHILE FUNDS WITH LONGER DURATIONS PERFORM BETTER WHEN RATES DECLINE. THERE IS NO GUARANTEE THAT ANY SECTORS MENTIONED WILL CONTINUE TO PERFORM WELL OR BE HELD BY THE FUND IN THE FUTURE. 3 <Page> PORTFOLIO COMPOSITION** <Table> Corporate Bonds 49.7% Asset-Backed Securities 19.8 U.S. Government Agencies -- Bonds 12.7 Mortgage-Backed Securities 8.5 U.S. Treasury Notes 5.0 Foreign Government Obligations 1.7 U.S. Government Agencies -- CMOs 1.5 Short-Term Investments 1.1 </Table> LONG-TERM CREDIT ANALYSIS <Table> Aaa/AAA 50.5% Aa/AA 13.8 A/A 20.5 Baa/BBB 15.1 Ba/BB 0.1 </Table> DATA AS OF APRIL 30, 2005.

This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 11/01/04 - 04/30/05. ACTUAL EXPENSES The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line of the table below provides information about hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the second line of the table is useful in comparing ongoing costs, and will not help you determine the relative total cost of owning different funds that have transactional costs, such as sales charges (loads), and redemption fees, or exchange fees. <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING PERIOD * ------------- ------------- --------------- 11/01/04 - 11/01/04 04/30/05 04/30/05 ------------- ------------- --------------- Actual (0.35% return) $ 1,000.00 $ 1,003.50 $ 3.83 Hypothetical (5% annual return before expenses) $ 1,000.00 $ 1,020.98 $ 3.86 </Table> - ---------- * EXPENSES ARE EQUAL TO THE FUND'S ANNUALIZED EXPENSE RATIO OF 0.77% MULTIPLIED BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY 181/365 (TO REFLECT THE ONE-HALF YEAR PERIOD). 8 <Page> INVESTMENT ADVISORY AGREEMENT APPROVAL NATURE, EXTENT AND QUALITY OF SERVICES The Board reviewed and considered the nature and extent of the investment advisory services provided by the Investment Adviser under the Advisory Agreement, including portfolio management, investment research and fixed income securities trading. The Board also reviewed and considered the nature and extent of the non-advisory, administrative services provided by the Fund's Administrator under the Administration Agreement, including accounting, clerical, bookkeeping, compliance, business management and planning, and the provision of supplies, office space and utilities at the Adviser's expense. (The Investment Adviser and the Administrator together are referred to as the "Adviser" and the Advisory and Administration Agreements together are referred to as the "Management Agreement.") The Board also compared the nature of the services provided by the Adviser with similar services provided by non-affiliated advisers as reported to the Board by Lipper Inc. ("Lipper"). The Board reviewed and considered the qualifications of the portfolio managers, the senior administrative managers and other key personnel of the Adviser who provide the administrative and investment advisory services to the Fund. The Board determined that the Adviser's portfolio managers and key personnel are well qualified by education and/or training and experience to perform the services in an efficient and professional manner. The Board concluded that the nature and extent of the advisory and administrative services provided were necessary and appropriate for the conduct of the business and investment activities of the Fund. The Board also concluded that the overall quality of the advisory and administrative services was satisfactory. PERFORMANCE RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS The Board reviewed the Fund's performance for one-, three- and five-year periods ended November 30, 2004, as shown in reports provided by Lipper (the "Lipper Reports"), compared to the performance of comparable funds selected by Lipper (the "performance peer group"), and noted that the Fund's performance was lower than its performance peer group average for all three periods. The Adviser informed the Board that the Fund's relative performance was hindered during a period of declining interest rates due to the defensive positioning of the Fund's portfolio. The Board discussed with the Adviser possible steps to improve performance. The Board concluded that the relative underperformance was understandable in view of the defensive positioning and corresponding lower risk of the Fund's investments. FEES RELATIVE TO OTHER FUNDS MANAGED BY THE ADVISER WITH COMPARABLE INVESTMENT STRATEGIES The Board reviewed the advisory and administrative fees (together, the "management fee") paid by the Fund under the Management Agreement. The Board noted that the management fee rate was higher than the management fee rates charged by the Adviser to any other funds it manages with investment strategies comparable to those of the Fund. The Board also noted, as discussed below, that the rate was competitive with contractual rates charged by other advisers for comparable funds. 9 <Page> FEES AND EXPENSES RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS The Board reviewed the management fee rate and total expense ratio of the Fund. The Board noted that: (i) the Fund's management fee rate was higher than the average management fee rate for funds, selected by Lipper (the "expense peer group"), managed by other advisers with investment strategies comparable to those of the Fund, as shown in the Lipper Report for the Fund; and (ii) the Fund's total expense ratio was slightly higher than the average total expense ratio of the mutual funds included in the Fund's expense peer group. The Board also noted that most of the other funds in the expense peer group were waiving part of their fees. The Board noted that the fee waivers by those funds were not contractual obligations and could be terminated without shareholder consent and, therefore, that the average fee excluding these waivers was a more valid comparison. The Board concluded that the Fund's contractual management fee and total expense ratio were competitive with those of the Fund's expense peer group. BREAKPOINTS AND ECONOMIES OF SCALE The Board reviewed the structure of the Fund's management fee schedule under the Management Agreement and noted that it includes breakpoints. The Board also reviewed the level of the Fund's management fee and noted that the fee, as a percentage of the Fund's net assets, would decrease as net assets increase because the management fee includes breakpoints. The Board concluded that the Fund's management fee would reflect economies of scale as assets increase. PROFITABILITY OF ADVISER AND AFFILIATES The Board considered and reviewed information concerning the costs incurred and profits realized by the Adviser and its affiliates during the last two years from their relationship with the Fund and the Morgan Stanley Fund Complex and reviewed with the Controller of the Adviser the cost allocation methodology used to determine the Adviser's profitability. Based on their review of the information they received, the Board concluded that the profits earned by the Adviser and its affiliates were not excessive in light of the advisory, administrative and other services provided to the Fund. FALL-OUT BENEFITS The Board considered so-called "fall-out benefits" derived by the Adviser and its affiliates from their relationship with the Fund and the Fund Complex, such as "float" benefits derived from handling of checks for purchases and redemptions of Fund shares through a broker-dealer affiliate of the Adviser. The Board considered the float benefits and concluded that they were relatively small. 10 <Page> SOFT DOLLAR BENEFITS The Board considered whether the Adviser realizes any benefits from commissions paid to brokers who execute securities transactions for the Fund ("soft dollars"). The Board noted that the Fund invests only in fixed income securities, which do not generate soft dollars. ADVISER FINANCIALLY SOUND AND FINANCIALLY CAPABLE OF MEETING THE FUND'S NEEDS The Board considered whether the Adviser is financially sound and has the resources necessary to perform its obligations under the Management Agreement. The Board noted that the Adviser's operations remain profitable, although increased expenses in recent years have reduced the Adviser's profitability. The Board concluded that the Adviser has the financial resources necessary to fulfill its obligations under the Management Agreement. HISTORICAL RELATIONSHIP BETWEEN THE FUND AND THE ADVISER The Board also reviewed and considered the historical relationship between the Fund and the Adviser, including the organizational structure of the Adviser, the policies and procedures formulated and adopted by the Adviser for managing the Fund's operations and the Board's confidence in the competence and integrity of the senior managers and key personnel of the Adviser. The Board concluded that it is beneficial for the Fund to continue its relationship with the Adviser. OTHER FACTORS AND CURRENT TRENDS The Board considered the controls and procedures adopted and implemented by the Adviser and monitored by the Fund's Chief Compliance Officer and concluded that the conduct of business by the Adviser indicates a good faith effort on its part to adhere to high ethical standards in the conduct of the Fund's business. GENERAL CONCLUSION After considering and weighing all of the above factors, the Board concluded it would be in the best interest of the Fund and its shareholders to approve renewal of the Management Agreement for another year. 11 <Page> MORGAN STANLEY LIMITED DURATION FUND PORTFOLIO OF INVESTMENTS - APRIL 30, 2005 <Table> <Caption> PRINCIPAL AMOUNT IN COUPON MATURITY THOUSANDS RATE DATE VALUE - ----------------------------------------------------------------------------------------------------------- CORPORATE BONDS (49.7%) AEROSPACE & DEFENSE (0.4%) $ 615 McDonnell Douglas Corp. 6.875% 11/01/06 $ 638,839 465 Northrop Grumman Corp. 4.079 11/16/06 464,998 105 Raytheon Co. 6.75 08/15/07 110,460 385 Raytheon Co. 8.30 03/01/10 445,099 --------------- 1,659,396 --------------- AIR FREIGHT/COURIERS (0.1%) 540 Fedex Corp. 2.65 04/01/07 525,051 --------------- AIRLINES (0.1%) 615 Southwest Airlines Co.

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 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 policies: A. VALUATION OF INVESTMENTS -- (1) certain portfolio securities may be valued by an outside pricing service approved by the Fund's Trustees (2) 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; (3) futures are valued at the latest price published by the commodities exchange on which they trade; (4) when market quotations are not readily available or Morgan Stanley Investment Advisors Inc. (the "Investment Adviser") 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; 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 Adviser, 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. 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 26 <Page> 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 ADVISORY/ADMINISTRATION AGREEMENTS Effective November 1, 2004, pursuant to an Investment Advisory Agreement with the Investment Adviser, the Fund pays an advisory 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: 0.52% of the portion of the daily net assets not exceeding $1 billion; 0.47% to the portion of daily net assets exceeding $1 billion but not exceeding $2 billion and 0.42% of the portion of daily net assets exceeding $2 billion. Effective November 1, 2004, pursuant to an Administration Agreement with Morgan Stanley Services Company Inc. (the Administrator"), an affiliate of the Investment Adviser, the Fund pays an administration fee, accrued daily and payable monthly, by applying the annual rate of 0.08% to the Fund's daily net assets. Prior to November 1, 2004, the Fund had retained the Investment Adviser to provide administrative services and to manage the investment of the Fund's assets pursuant to an investment agreement pursuant to which the Fund paid the Investment Adviser a monthly 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: 0.60% of the portion of the daily net assets not exceeding $1 billion; 0.55% to the portion of daily net assets exceeding $1 billion but not exceeding $2 billion and 0.50% of the portion of daily net assets exceeding $2 billion. 27 <Page> 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, 2005 were $353,175,544, and $521,245,740, respectively. Included in the aforementioned are purchases and sales/prepayments of U.S. Government securities of $273,470,195 and $423,312,043, respectively. Morgan Stanley Trust, an affiliate of the Investment Adviser and Administrator, is the Fund's transfer agent. At April 30, 2005, the Fund had transfer agent fees and expenses payable of approximately $5,200. The Fund has an unfunded Deferred Compensation Plan (the "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. Each eligible Trustee generally may elect to have the deferred amounts credited with a return equal to the total return on one or more of the Morgan Stanley funds that are offered as investment options under the Compensation Plan. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Fund. 4. SHARES OF BENEFICIAL INTEREST Transactions in shares of beneficial interest were as follows: <Table> <Caption> FOR THE YEAR FOR THE YEAR ENDED ENDED APRIL 30, 2005 APRIL 30, 2004 ---------------------------- ---------------------------- SHARES AMOUNT SHARES AMOUNT ----------- -------------- ----------- -------------- Sold 13,944,535 $ 129,742,246 48,705,797 $ 466,638,947 Reinvestment of dividends 1,321,375 12,255,388 1,560,045 14,878,957 ----------- -------------- ----------- -------------- 15,265,910 141,997,634 50,265,842 481,517,904 Redeemed (28,350,418) (262,869,327) (42,728,082) (408,117,384) ----------- -------------- ----------- -------------- Net increase (decrease) (13,084,508) $ (120,871,693) 7,537,760 $ 73,400,520 =========== ============== =========== ============== </Table> 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 28 <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. The tax character of distributions paid was as follows: <Table> <Caption> FOR THE YEAR FOR THE YEAR ENDED ENDED APRIL 30, 2005 APRIL 30, 2004 -------------- -------------- Ordinary income $ 16,513,968 $ 19,690,002 ============== ============== </Table> As of April 30, 2005, the tax-basis components of accumulated losses were as follows: <Table> Undistributed ordinary income $ 103,552 Undistributed long-term gains -- -------------- Net accumulated earnings 103,552 Capital loss carryforward* (19,274,017) Post-October losses (1,742,346) Temporary differences (70,274) Net unrealized depreciation (6,676,851) -------------- Total accumulated losses $ (27,659,936) ============== </Table> *As of April 30, 2005, the Fund had a net capital loss carryforward of $19,274,017 of which $1,656,930 will expire on April 30, 2006, $20,504 will expire on April 30, 2007, $51,242 will expire on April 30, 2008, $2,035,052 will expire on April 30, 2009, $1,582,163 will expire on April 30, 2011, $2,183,130 will expire on April 30, 2012 and $11,744,996 will expire on April 30, 2013 to offset future capital gains to the extent provided by regulations. As of April 30, 2005, 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 $151,743, accumulated net realized loss was charged $5,894,691 and dividends in excess of net investment income was credited $6,046,434. 29 <Page> 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 of Assets and Liabilities. The Fund bears the risk of an unfavorable change in the value of the underlying securities. Risk may also arise upon entering into contracts from the potential inability of counterparts to meet the terms of their contacts. 7. EXPENSE OFFSET The expense offset represents a reduction of the custodian fees for earnings on cash balances maintained by the Fund. 8. LEGAL MATTERS The Investment Adviser, certain affiliates of the Investment Adviser, certain officers of such affiliates and certain investment companies advised by the Investment Adviser or its affiliates, including the Fund, are named as defendants in a consolidated class action. This consolidated action also names as defendants certain individual Trustees and Directors of the Morgan Stanley funds. The consolidated amended complaint generally alleges that defendants, including the Fund, violated their statutory disclosure obligations and fiduciary duties by failing properly to disclose (i) that the Investment Adviser and certain affiliates of the Investment Adviser allegedly offered economic incentives to brokers and others to recommend the funds advised by the Investment Adviser or its affiliates to investors rather than funds managed by other companies, and (ii) that the funds advised by the Investment Adviser or its affiliates, including the Fund, allegedly paid excessive commissions to brokers in return for their efforts to recommend these funds to investors. The complaint seeks, among other things, unspecified compensatory damages, rescissionary damages, fees and costs. The defendants have moved to dismiss the action and intend to otherwise vigorously defend it. On March 10, 2005, Plaintiffs sought leave to supplement their complaint to assert claims on behalf of other investors. While the Fund and Adviser believe that each has meritorious defenses, the ultimate outcome of this matter 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 this matter. 30 <Page> MORGAN STANLEY LIMITED DURATION FUND FINANCIAL HIGHLIGHTS Selected ratios and per share data for a share of beneficial interest outstanding throughout each period: <Table> <Caption> FOR THE YEAR ENDED APRIL 30, -------------------------------------------------------------------------- 2005 2004 2003 2002 2001 ---------- ---------- ---------- ---------- ---------- SELECTED PER SHARE DATA: Net asset value, beginning of period $ 9.41 $ 9.68 $ 9.59 $ 9.44 $ 9.20 ---------- ---------- ---------- ---------- ---------- Income (loss) from investment operations: Net investment income 0.19 0.17 0.24 0.41 0.55 Net realized and unrealized gain (loss) (0.08) (0.07) 0.13 0.19 0.24 ---------- ---------- ---------- ---------- ---------- Total income from investment operations 0.11 0.10 0.37 0.60 0.79 ---------- ---------- ---------- ---------- ---------- Less dividends from net investment income (0.35) (0.37) (0.28) (0.45) (0.55) ---------- ---------- ---------- ---------- ---------- Net asset value, end of period $ 9.17 $ 9.41 $ 9.68 $ 9.59 $ 9.44 ========== ========== ========== ========== ========== TOTAL RETURN+ 1.20% 0.99% 3.93% 6.50% 8.82% RATIOS TO AVERAGE NET ASSETS: Expenses 0.76%(1) 0.85%(1) 0.84%(2) 0.80%(2) 0.80%(2) Net investment income 2.63% 1.75% 1.90% 3.94% 5.87% SUPPLEMENTAL DATA: Net assets, end of period, in thousands $ 356,124 $ 488,409 $ 429,409 $ 166,631 $ 109,917 Portfolio turnover rate 82% 240% 217% 327% 133% </Table> - ---------- + CALCULATED BASED ON THE NET ASSET VALUE AS OF THE LAST BUSINESS DAY OF THE PERIOD.

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 the standards of the Public Company Accounting Oversight Board (United States). 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. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of April 30, 2005, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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, 2005, 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.

STATEMENT OF PRINCIPLES The Audit Committee of the Board is required to review and, in its sole discretion, pre-approve all Covered Services to be provided by the Independent Auditors to the Fund and Covered Entities in order to assure that services performed by the Independent Auditors do not impair the auditor's independence from the Fund. The SEC has issued rules specifying the types of services that an independent auditor may not provide to its audit client, as well as the audit committee's administration of the engagement of the independent auditor. The SEC's rules establish two different approaches to pre-approving services, which the SEC considers to be equally valid. Proposed services either: may be pre-approved without consideration of specific case-by-case services by the Audit Committee ("GENERAL PRE-APPROVAL"); or require the specific pre-approval of the Audit Committee or its delegate ("SPECIFIC PRE-APPROVAL"). The Audit Committee believes that the combination of these two approaches in this Policy will result in an effective and efficient procedure to pre-approve services performed by the Independent Auditors. As set forth in this Policy, unless a type of service has received general pre-approval, it will require specific pre-approval by the Audit Committee (or by any member of the Audit Committee to which pre-approval authority has been delegated) if it is to be provided by the Independent Auditors. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval by the Audit Committee. The appendices to this Policy describe the Audit, Audit-related, Tax and All Other services that have the general pre-approval of the Audit Committee. The term of any general pre-approval is 12 months from the date of pre-approval, unless the Audit Committee considers and provides a different period and states otherwise. The Audit Committee will annually review and pre-approve the services that may be provided by the Independent Auditors without obtaining specific pre-approval from the Audit Committee. The Audit Committee will add to or subtract from the list of general pre-approved services from time to time, based on subsequent determinations. - ---------- (1) This Audit Committee Audit and Non-Audit Services Pre-Approval Policy and Procedures (the "POLICY"), adopted as of the date above, supersedes and replaces all prior versions that may have been adopted from time to time. <Page> The purpose of this Policy is to set forth the policy and procedures by which the Audit Committee intends to fulfill its responsibilities. It does not delegate the Audit Committee's responsibilities to pre-approve services performed by the Independent Auditors to management. The Fund's Independent Auditors have reviewed this Policy and believes that implementation of the Policy will not adversely affect the Independent Auditors' independence. 2. DELEGATION As provided in the Act and the SEC's rules, the Audit Committee may delegate either type of pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting. 3. AUDIT SERVICES The annual Audit services engagement terms and fees are subject to the specific pre-approval of the Audit Committee. Audit services include the annual financial statement audit and other procedures required to be performed by the Independent Auditors to be able to form an opinion on the Fund's financial statements. These other procedures include information systems and procedural reviews and testing performed in order to understand and place reliance on the systems of internal control, and consultations relating to the audit. The Audit Committee will approve, if necessary, any changes in terms, conditions and fees resulting from changes in audit scope, Fund structure or other items. In addition to the annual Audit services engagement approved by the Audit Committee, the Audit Committee may grant general pre-approval to other Audit services, which are those services that only the Independent Auditors reasonably can provide. Other Audit services may include statutory audits and services associated with SEC registration statements (on Forms N-1A, N-2, N-3, N-4, etc.), periodic reports and other documents filed with the SEC or other documents issued in connection with securities offerings. The Audit Committee has pre-approved the Audit services in Appendix B.1. All other Audit services not listed in Appendix B.1 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 4. AUDIT-RELATED SERVICES Audit-related services are assurance and related services that are reasonably related to the performance of the audit or review of the Fund's financial statements and, to the extent they are Covered Services, the Covered Entities or that are traditionally performed by the Independent Auditors. Because the Audit Committee believes that the provision of Audit-related services does not impair the independence of the auditor and is consistent with the SEC's rules on auditor independence, the Audit Committee may grant general pre-approval to Audit-related services. Audit-related services include, among others, accounting consultations related to accounting, financial reporting or disclosure matters <Page> not classified as "Audit services"; assistance with understanding and implementing new accounting and financial reporting guidance from rulemaking authorities; agreed-upon or expanded audit procedures related to accounting and/or billing records required to respond to or comply with financial, accounting or regulatory reporting matters; and assistance with internal control reporting requirements under Forms N-SAR and/or N-CSR. The Audit Committee has pre-approved the Audit-related services in Appendix B.2. All other Audit-related services not listed in Appendix B.2 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 5. TAX SERVICES The Audit Committee believes that the Independent Auditors can provide Tax services to the Fund and, to the extent they are Covered Services, the Covered Entities, such as tax compliance, tax planning and tax advice without impairing the auditor's independence, and the SEC has stated that the Independent Auditors may provide such services. Pursuant to the preceding paragraph, the Audit Committee has pre-approved the Tax Services in Appendix B.3. All Tax services in Appendix B.3 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 6. ALL OTHER SERVICES The Audit Committee believes, based on the SEC's rules prohibiting the Independent Auditors from providing specific non-audit services, that other types of non-audit services are permitted. Accordingly, the Audit Committee believes it may grant general pre-approval to those permissible non-audit services classified as All Other services that it believes are routine and recurring services, would not impair the independence of the auditor and are consistent with the SEC's rules on auditor independence. The Audit Committee has pre-approved the All Other services in Appendix B.4. Permissible All Other services not listed in Appendix B.4 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 7. PRE-APPROVAL FEE LEVELS OR BUDGETED AMOUNTS Pre-approval fee levels or budgeted amounts for all services to be provided by the Independent Auditors will be established annually by the Audit Committee. Any proposed services exceeding these levels or amounts will require specific pre-approval by the Audit Committee. The Audit Committee is mindful of the overall relationship of fees for audit and non-audit services in determining whether to pre-approve any such services. 8. PROCEDURES All requests or applications for services to be provided by the Independent Auditors that do not require specific approval by the Audit Committee will be submitted to the Fund's Chief Financial Officer and must include a detailed description of the services to be <Page> rendered. The Fund's Chief Financial Officer will determine whether such services are included within the list of services that have received the general pre-approval of the Audit Committee. The Audit Committee will be informed on a timely basis of any such services rendered by the Independent Auditors. Requests or applications to provide services that require specific approval by the Audit Committee will be submitted to the Audit Committee by both the Independent Auditors and the Fund's Chief Financial Officer, and must include a joint statement as to whether, in their view, the request or application is consistent with the SEC's rules on auditor independence. The Audit Committee has designated the Fund's Chief Financial Officer to monitor the performance of all services provided by the Independent Auditors and to determine whether such services are in compliance with this Policy. The Fund's Chief Financial Officer will report to the Audit Committee on a periodic basis on the results of its monitoring. Both the Fund's Chief Financial Officer and management will immediately report to the chairman of the Audit Committee any breach of this Policy that comes to the attention of the Fund's Chief Financial Officer or any member of management. 9. ADDITIONAL REQUIREMENTS The Audit Committee has determined to take additional measures on an annual basis to meet its responsibility to oversee the work of the Independent Auditors and to assure the auditor's independence from the Fund, such as reviewing a formal written statement from the Independent Auditors delineating all relationships between the Independent Auditors and the Fund, consistent with Independence Standards Board No. 1, and discussing with the Independent Auditors its methods and procedures for ensuring independence. 10. COVERED ENTITIES Covered Entities include the Fund's investment adviser(s) and any entity controlling, controlled by or under common control with the Fund's investment adviser(s) that provides ongoing services to the Fund(s). Beginning with non-audit service contracts entered into on or after May 6, 2003, the Fund's audit committee must pre-approve non-audit services provided not only to the Fund but also to the Covered Entities if the engagements relate directly to the operations and financial reporting of the Fund. This list of Covered Entities would include: MORGAN STANLEY RETAIL FUNDS Morgan Stanley Investment Advisors Inc. Morgan Stanley & Co. Incorporated Morgan Stanley DW Inc.
