MARKET CONDITIONS Equity markets performed well during the six-month period ended May 31, 2004, after the strong rally that began in March 2003. The market during this period can be characterized as having two distinct phases: the first, resembling the rally seen earlier in the year and the second, showing a marked shift in investor sentiment. During December 2003 and January 2004 the market rallied due to low interest rates, low inflationary concerns -- largely because of slow job growth and the capture of Saddam Hussein. The Federal Open Market Committee (the Fed) stated that they would be "patient" with low interest rates in the absence of clear inflationary pressures. Investors remained focused on high-beta sectors as the threat of interest-rate hikes stayed low; as a result, information technology and other economically sensitive sectors led the market, though all sectors returned positive results. January 2004 began promisingly on the heels of a strong earnings report by Intel. While its earnings were strong, Intel's guidance on future margins led to profit taking in the information technology sector; the profit taking spread to other sectors in February after a weak University of Michigan consumer sentiment report. Then investors began to shift assets toward more-defensive, more attractively valued stocks after Fed Chairman Alan Greenspan indicated that interest rates would likely rise in the future and after more mixed economic data came out. As investors struggled with interest-rate uncertainty and the mixed economic data, the market fluctuated without a discernible trend. Large-cap stocks outperformed both small- and mid-cap issues as investors sought dividend-paying stocks with stable earnings. Mid-cap stocks lagged both their smaller and larger counterparts. 2 <Page> PERFORMANCE ANALYSIS Performance for Morgan Stanley KLD Social Index Fund was mixed during this period. Share classes A and D outperformed both the KLD Large Cap Social(SM) Index* (The KLD Index) and the Lipper Large-Cap Core Funds Index, while share classes B & C only outperformed the noted Lipper Index. The Fund's investment objective is to seek to provide investment results that, before expenses, correspond to the total return of the KLD Large Cap Social(SM) Index. During the period, the Index had a high exposure to the information technology sector and so did the Fund. Unfortunately, information technology was the worst-performing sector in the market and the Fund was hurt by such key holdings as Intel, Veritas and Texas Instruments. Performance was also hurt by basic materials and utilities companies. On a more positive note, the Fund's holdings in several key sectors performed well. Financials was one of the strongest-performing sectors, led by the low-cost insurer American International Group (AIG). AIG was boosted by strong profit reports in January and April. Additionally, the health care supply company Johnson & Johnson and consumer staples supplier Procter & Gamble aided the Fund's performance as investors sought their more-stable revenue streams. * THE KLD LARGE CAP SOCIAL(SM) INDEX BEGINS WITH THE RUSSELL 1000 INDEX.

ORGANIZATION AND ACCOUNTING POLICIES Morgan Stanley KLD Social Index Fund (the "Fund") is registered under the Investment Company Act of 1940, as amended (the "Act"), as a non-diversified, open-end management investment company. The Fund's investment objective is to provide investment results that before expenses corresponds to the total return of the KLD Large Cap Social(SM) Index ("KLD Index"). The Fund was organized as a Massachusetts business trust on April 6, 2001 and commenced operations on July 13, 2001. 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 Stock Exchange ("NYSE") 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 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. Occasionally, developments affecting the closing prices of securities and other assets may occur between the times at which valuations of such securities are determined (that is, close of the foreign market on which the securities trade) and the close of business on the NYSE. If developments occur during such periods that are expected to materially affect the value of such securities, such valuations may be adjusted to reflect the estimated fair value of such securities as of the close of the NYSE, as determined in good faith by the Fund's Trustees or by the Investment Manager using a pricing service and/or procedures approved 18 <Page> by the Trustees of the Fund; and (7) 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. 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. 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. 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. 19 <Page> 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 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 0.20% to the average net assets of the Fund determined as of the close of each business day. Prior to May 1, 2004, the annual rate was 0.40% of the average net assets of the Fund. The Investment Manager has agreed to waive its fee and assume all operating expenses (except for distribution fees) until such time as the Fund has $50 million of net assets or December 31, 2004, whichever occurs first. Thereafter, the Investment Manager has agreed to assume all operating expenses (except for distribution fees) and to waive the compensation provided for in its Investment Management Agreement to the extent that such expenses and compensation on an annual basis exceed 0.40% of the daily net assets of the Fund. At May 31, 2004, included in the Statement of Assets and Liabilities is a receivable from affiliate, which represents expense reimbursements due to the Fund. 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 -- up to 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 $1,153,715 at May 31, 2004. 20 <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 six months ended May 31, 2004, the distribution fee was accrued for Class A shares and Class C shares at the annual rate of 0.20% and 0.85%, respectively. The Distributor has informed the Fund that for the six months ended May 31, 2004, it received contingent deferred sales charges from certain redemptions of the Fund's Class A shares, Class B shares and Class C shares of $6, $10,730 and $40, respectively and received $12,536 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 six months ended May 31, 2004 aggregated $3,438,935 and $1,234,567, respectively. Morgan Stanley Trust, an affiliate of the Investment Manager and Distributor, is the Fund's transfer agent. At May 31, 2004, the Fund had transfer agent fees and expenses payable of approximately $1,400. Effective April 1, 2004, the Fund began 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. 21 <Page> 5.

PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS The Fund may purchase and sell stock index futures ("futures contracts") for the following reasons: to simulate full investment in the KLD Index while retaining a cash balance for fund management purposes; to facilitate trading; to reduce transaction costs; or to seek higher investment returns when a futures contract is priced more attractively than stocks comprising the KLD Index. 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. Risks may also arise upon entering into these contracts from the potential inability of the counter parties to meet the terms of their contracts. 22 <Page> 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. As of November 30, 2003, the Fund had a net capital loss carryforward of $3,123,322 of which $19,969 will expire on November 30, 2009, $2,198,221 will expire on November 30, 2010 and $905,132 will expire on November 30, 2011 to offset future capital gains to the extent provided by regulations. As of November 30, 2003, the Fund had temporary book/tax differences primarily attributable to capital loss deferrals on wash sales and mark-to-market of open contracts. 8. LEGAL MATTERS The Investment Manager, certain affiliates of the Investment Manager, certain officers of such affiliates and certain investment companies advised by the Investment Manager or its affiliates, including the Fund, are named as defendants in a number of similar class action complaints which were recently consolidated. 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 Manager and certain affiliates of the Investment Manager allegedly offered economic incentives to brokers and others to recommend the funds advised by the Investment Manager or its affiliates to investors rather than funds managed by other companies, and (ii) that the funds advised by the Investment Manager or its affiliates, including the Fund, allegedly paid excessive commissions to brokers in return for their 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 otherwise vigorously to defend it. While the Fund believes that it 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. 23 <Page> MORGAN STANLEY KLD SOCIAL INDEX FUND FINANCIAL HIGHLIGHTS Selected ratios and per share data for a share of beneficial interest outstanding throughout each period: <Table> <Caption> FOR THE PERIOD FOR THE SIX FOR THE YEAR FOR THE YEAR JULY 13, 2001* MONTHS ENDED ENDED ENDED THROUGH MAY 31, 2004 NOVEMBER 30, 2003 NOVEMBER 30, 2002 NOVEMBER 30, 2001 ------------ ----------------- ----------------- ----------------- (UNAUDITED) CLASS A SHARES SELECTED PER SHARE DATA: Net asset value, beginning of period $ 8.88 $ 7.73 $ 9.39 $ 10.00 ---------- ---------- ---------- ---------- Income (loss) from investment operations: Net investment income++ 0.05 0.10 0.09 0.03 Net realized and unrealized gain (loss) 0.46 1.17 (1.70) (0.64) ---------- ---------- ---------- ---------- Total income (loss) from investment operations 0.51 1.27 (1.61) (0.61) ---------- ---------- ---------- ---------- Less dividends from net investment income (0.08) (0.12) (0.05) - ---------- ---------- ---------- ---------- Net asset value, end of period $ 9.31 $ 8.88 $ 7.73 $ 9.39 ========== ========== ========== ========== TOTAL RETURN+ 5.93%(1) 16.72% (17.25)% (6.10)%(1) RATIOS TO AVERAGE NET ASSETS(3)(4): Expenses 0.20%(2) 0.20% 0.24% 0.25%(2) Net investment income 1.16%(2) 1.29% 1.01% 0.85%(2) SUPPLEMENTAL DATA: Net assets, end of period, in thousands $ 2,311 $ 2,103 $ 756 $ 329 Portfolio turnover rate 8%(1) 24% 13% 3%(1) </Table> - ---------- * COMMENCEMENT OF OPERATIONS. ++ THE PER SHARE AMOUNTS WERE COMPUTED USING AN AVERAGE NUMBER OF SHARES OUTSTANDING DURING THE PERIOD. + DOES NOT REFLECT THE DEDUCTION OF SALES CHARGE.
