See Performance Summary for standardized performance and benchmark information. MARKET CONDITIONS The Federal Open Market Committee (the "Fed") raised the federal funds target rate by 25 basis points at both the May and June meetings, but then chose to pause at the following three meetings. Comments made by Fed members after their May and June meetings indicated that they will rely heavily on economic data in making future decisions concerning the direction of interest rates. In fact, based on these comments it appears that the Fed will be driven by the weight of the economic data more so now than perhaps at anytime over the past few years. At first glance, the third quarter gross domestic product (GDP) report was disappointing, with the real economy expanding at a 1.6 percent annualized rate during the period -- its weakest showing in three years. A further analysis, however, suggests a more favorable view of the economy. Most observers expected that housing would be a drag on GDP, and it certainly was to the tune of approximately one full percentage point during the period. However, this is far from a crushing blow to an economy that had been growing at or above its long-term potential growth rate for the past few years. There is also evidence that home sellers are responding to the housing market correction by either withdrawing inventory from the market or by adjusting asking prices -- both of which may tend to limit the severity and longevity of the housing correction. Moreover, the so-called negative wealth effect caused by lower home prices is open to debate. Empirical evidence shows that the assumed relationships between mortgage equity withdrawals and consumer spending are unstable in both the short run and the long run. A further analysis of the third quarter GDP report also revealed strong gains in both non-residential real restate and in real equipment spending. We are not suggesting that investors ignore the relatively weak headline GDP number; instead, we are suggesting that there is more to the report than meets the eye, especially when evaluated within the context of other economic barometers. Where does all of this leave the Fed? With inflation above 2 percent and expectations for strong growth, we believe there is little support in any of the recent data to justify a more accommodative monetary policy. If anything, there is cause for concern on the inflation front, especially with tight labor markets. Accordingly, a higher federal funds rate may well be necessary to control the level of inflation and, accordingly, nominal economic growth rates. Within the government sector, U.S. Treasuries underperformed over the six-month period because of 2 their high sensitivity to fluctuating interest rates and their relatively low yields. Yield spreads (a measure of market risk) of agency debentures and mortgages remained tight relative to Treasuries. As is typical during periods of declining interest rates, prepayment speeds on mortgages rose, causing lower-coupon mortgages to outperform. Within the investment-grade portion of the corporate sector, lower-rated issues (BBB- and A-rated) outpaced higher-rated issues (AA-rated and above). Industrials posted the highest returns, followed by utilities and financials. Overall for the period, longer dated corporate issues underperformed shorter-dated issues. PERFORMANCE ANALYSIS Morgan Stanley Limited Duration Fund underperformed the Lehman Brothers U.S. Credit Index (1-5 Year) and the Lipper Short Investment Grade Bond Funds Index for the six months ended October 31, 2006, assuming no deduction of applicable sales charges. During the period, we kept the Fund's overall duration* modestly below that of the relevant indices. This posture was beneficial as interest rates rose across the market, especially in the short- and intermediate-portions of the yield curve. The portfolio had a small exposure to higher-coupon mortgage backed securities which benefited performance. Additionally, the portfolio had significant exposure to adjustable rate mortgages which enhanced performance. Within the credit section of the Portfolio, we employed a defensive strategy with a focus on higher-quality securities, which detracted from relative performance. However, strong security selection contributed positively to performance for the period. There is no guarantee that any sectors mentioned will continue to perform as discussed herein or that securities in such sectors will be held by the Fund in the future. *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. 3 <Table> <Caption> PORTFOLIO COMPOSITION** Corporate Bonds 43.3% Private Issues -- CMOs 23.4 Mortgage-Backed Securities 17.9 Asset-Backed Securities 8.2 U.S. Government Agencies -- CMOs 2.8 Short-Term Investments 4.4 </Table> <Table> <Caption> LONG-TERM CREDIT ANALYSIS Aaa/AAA 53.6% Aa/AA 12.4 A/A 18.4 Baa/BBB 15.6 </Table> ** Does not include open long futures contracts with an underlying face amount of $34,544,658 with unrealized appreciation of $56,537 and open short futures contracts with an underlying face amount of $11,717,438 and unrealized depreciation of $69,189.

Morgan Stanley is a full-service securities firm engaged in securities trading and brokerage activities, investment banking, research and analysis, financing and financial advisory services. INVESTMENT STRATEGY The Fund will normally invest at least 65 percent of its assets in securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities (including zero coupon securities), investment grade mortgage-backed securities, including collateralized mortgage obligations, and investment grade corporate and other types of bonds. In selecting portfolio investments to purchase or sell, the "Investment Adviser," Morgan Stanley Investment Advisors Inc., considers both domestic and international economic developments, interest rate levels, the steepness of the yield curve and other factors, and seeks to maintain an overall average duration for the Fund's portfolio of three years or less.

For most recent month-end performance figures, please visit www.morganstanley.com or speak with your Financial Advisor. Investment returns and principal value will fluctuate and fund shares, when redeemed, may be worth more or less than their original cost. The table does not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. (1) The Lehman Brothers U.S. Credit Index (1-5 Year) includes U.S. corporate and specified foreign debentures and secured notes with maturities of one to five years. Indexes are unmanaged and their returns do not include any sales charges or fees. Such costs would lower performance. It is not possible to invest directly in an index. (2) The Lipper Short Investment Grade Bond Funds Index is an equally weighted performance index of the largest qualifying funds (based on net assets) in the Lipper Short Investment Grade Bond Funds classification. The Index, which is adjusted for capital gains distributions and income dividends, is unmanaged and should not be considered an investment. There are currently 30 funds represented in this Index. (3) Figure shown assumes reinvestment of all distributions. There are no sales charges. 6 EXPENSE EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees; and (2) ongoing costs, including advisory fees and other Fund expenses. 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 05/01/06 - 10/31/06. 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), redemption fees or exchange fees. <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING PERIOD * ------------- ------------- --------------- 05/01/06 - 05/01/06 10/31/06 10/31/06 ------------- ------------- --------------- Actual (2.28% return)....................................... $1,000.00 $1,022.80 $4.08 Hypothetical (5% annual return before expenses)............. $1,000.00 $1,021.17 $4.08 </Table> - ------------------ * Expenses are equal to the Fund's annualized expense ratio of 0.80% multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period). If the Fund had borne all of its expenses waived by the Investment Adviser and Administrator, the annualized expense ratios for the one-half period would have been 0.87%. 7 Morgan Stanley Limited Duration Fund PORTFOLIO OF INVESTMENTS - OCTOBER 31, 2006 (UNAUDITED) <Table> <Caption> PRINCIPAL AMOUNT IN COUPON MATURITY THOUSANDS RATE DATE VALUE - ----------------------------------------------------------------------------------------------------------- Corporate Bonds (44.8%) Aerospace & Defense (0.6%) $ 435 McDonnell Douglas Corp. ............................... 6.875% 11/01/06 $ 435,000 330 Northrop Grumman Corp. ................................ 4.079 11/16/06 329,833 65 Raytheon Co. .......................................... 6.15 11/01/08 66,125 55 Raytheon Co. .......................................... 6.75 08/15/07 55,522 ------------ 886,480 ------------ Air Freight/Couriers (0.3%) 385 FedEx Corp. ........................................... 2.65 04/01/07 380,623 ------------ Airlines (0.3%) 435 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 Fund will assess a 2% redemption fee, which is paid directly to the Fund, for shares redeemed within seven days of purchase, subject to certain exceptions. The redemption fee is designed to protect the Fund and its remaining shareholders from the effects of short-term trading. 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 including circumstances under which 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; (5) listed options are valued at the latest sale price on the exchange on which they are listed unless no sales of such options have taken place that day, in which case they are valued at the mean between their latest bid and asked price; and (6) 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 20 Morgan Stanley Limited Duration Fund NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2006 (UNAUDITED) continued 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 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. Options -- When the Fund writes a call option, an amount equal to the premium received is included in the Fund's Statement of Assets and Liabilities as a liability which is subsequently marked-to-market to reflect the current market value of the option written. If a written option either expires or the Fund enters into a closing purchase transaction, the Fund realizes a gain or loss without regard to any unrealized gain or loss on the underlying security or currency and the liability related to such option is extinguished. If a written call option is exercised, the Fund realizes a gain or loss from the sale of the underlying security or currency and the proceeds from such sale are increased by the premium originally received. When the Fund purchases a call or put option, the premium paid is recorded as an investment and is subsequently marked-to-market to reflect the current market value. If a purchased option expires, the Fund will realize a loss to the extent of the premium paid. If the Fund enters into a closing sale transaction, a gain or loss is realized for the difference between the proceeds from the sale and the cost of the option. If a put option is exercised, the cost of the security or currency sold upon exercise will be increased by the premium originally paid. If a call option is exercised, the cost of the security purchased upon exercise will be increased by the premium originally paid. F. 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. G. Dividends and Distributions to Shareholders -- Dividends and distributions to shareholders are recorded on the ex-dividend date. 21 Morgan Stanley Limited Duration Fund NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2006 (UNAUDITED) continued H. 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 Pursuant to an Investment Advisory Agreement with Morgan Stanley 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 the daily net assets exceeding $1 billion but not exceeding $2 billion and 0.42% of the portion of the daily net assets in excess of $2 billion. 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. Effective November 18, 2005, the Investment Adviser has agreed to cap the Fund's operating expenses for one year by assuming the Fund's "other expenses" and/or waiving the Fund's advisory fees, and the Administrator has agreed to waive the Fund's administrative fees, to the extent such operating expenses on an annualized basis exceed 0.80% of the average daily net assets of the Fund. 3. Security Transactions and Transactions with Affiliates The cost of purchases and proceeds from sales/maturities/prepayments of portfolio securities, excluding short-term investments, for the six months ended October 31, 2006 were $40,956,339, and $55,278,858, respectively. Included in the aforementioned are purchases and sales/prepayments of U.S. Government securities of $7,481,640 and $12,744,948, respectively. Morgan Stanley Trust, an affiliate of the Investment Adviser and Administration, is the Fund's transfer agent. 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 or she 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. 22 Morgan Stanley Limited Duration Fund NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2006 (UNAUDITED) continued 4. Shares of Beneficial Interest Transactions in shares of beneficial interest were as follows: <Table> <Caption> FOR THE SIX FOR THE YEAR MONTHS ENDED ENDED OCTOBER 31, 2006 APRIL 30, 2006 ------------------------- --------------------------- (unaudited) SHARES AMOUNT SHARES AMOUNT ---------- ------------ ----------- ------------- Sold............................................ 594,933 $ 5,348,340 3,479,165 $ 31,694,608 Reinvestment of dividends....................... 279,640 2,516,080 795,079 7,229,149 ---------- ------------ ----------- ------------- 874,573 7,864,420 4,274,244 38,923,757 Redeemed........................................

Expense Offset The expense offset represents a reduction of the fees and expenses for interest earned on cash balances maintained by the Fund with the transfer agent. 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"). For hedging and investment purposes, the Fund may also engage in transactions in listed and over-the-counter options. 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 contracts. 7. 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. 23 Morgan Stanley Limited Duration Fund NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2006 (UNAUDITED) continued As of April 30, 2006, the Fund had a net capital loss carryforward of $21,831,288 of which $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, $11,744,997 will expire on April 30, 2013 and $4,214,200 will expire on April 30, 2014 to offset future capital gains to the extent provided by regulations. As of April 30, 2006, 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 on debt securities. 8. New Accounting Pronouncements In July 2006, the Financial Accounting Standards Board (FASB) issued Interpretation 48, Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position must meet before being recognized in the financial statements. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Fund will adopt FIN 48 for the fiscal year ending 2008 and the impact to the Fund's financial statements, if any, is currently being assessed. In addition, in September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures. 24 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 SIX FOR THE YEAR ENDED APRIL 30, MONTHS ENDED ----------------------------------------------------------------- OCTOBER 31, 2006 2006 2005 2004 2003 2002 ---------------- --------- --------- --------- --------- --------- (unaudited) Selected Per Share Data: Net asset value, beginning of period... $9.02 $9.17 $9.41 $9.68 $9.59 $9.44 ----- ----- ----- ----- ----- ----- Income (loss) from investment operations: Net investment income.............. 0.17 0.16 0.19 0.17 0.24 0.41 Net realized and unrealized gain (loss)............................. 0.04 0.05 (0.08) (0.07) 0.13 0.19 ----- ----- ----- ----- ----- ----- Total income from investment operations............................ 0.21 0.21 0.11 0.10 0.37 0.60 ----- ----- ----- ----- ----- ----- Less dividends from net investment income................................
