SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE AND BENCHMARK INFORMATION. MARKET CONDITIONS For the 12-month period ended September 30, 2006, U.S. equity markets posted broadly positive returns. The S&P 500(R) returned 10.79 percent, including dividends. After many years of outperformance, small- and mid-cap equity indexes lagged their large-cap counterparts. The technology-sensitive Nasdaq-100 Index lagged other broad equity market measures, with a modestly positive return over the period. Although all S&P 500 sectors posted positive returns over the 12-month period, telecommunication services was by far the strongest large-cap sector, gaining 26.05 percent. Despite rising interest rates, financial services also posted strong returns, advancing 20.53 percent. The sector's strength can largely be attributed to phenomenal performance by both the real estate and diversified financials sub-sectors. Information technology produced the weakest sector returns over the period. Dragged down by semiconductors, technology hardware and equipment, and software and services, the sector returned a modest 3.26 percent. After several years of outperformance, the energy sector struggled over the period. The price of crude oil surged to a new all-time high of $77.23 per barrel in the second week of July, ahead of the hurricane season. As storm season passed with relatively little incident, oil prices fell precipitously through the balance of the period. Energy stocks struggled against falling oil prices through the last quarter of the period, and the sector advanced only 3.51 percent over the 12-month period. In response to strong economic fundamentals, the Federal Open Market Committee (the "Fed") raised rates six times over the period. Cooling commodity prices and moderating economic growth in the last quarter of the period led the Fed to pause its monetary tightening over the final two meetings of the period. As of September 30, 2006, the target federal funds rate was 5.25 percent. PERFORMANCE ANALYSIS Morgan Stanley Multi-Asset Class Fund underperformed the S&P 500(R) and the Lipper Flexible Portfolio Funds Index for the 12 months ended September 30, 2006, assuming no deduction of applicable sales charges. Although the Fund made several tactical moves, it nonetheless retained a high allocation to the information technology sector over the period through positions in both the Technology Fund and the Nasdaq-100 Index Fund. As technology stocks struggled throughout the period, the Fund's performance was adversely affected 2 <Page> by these allocations. A relative underweight in the financial services sector to the S&P 500, contributed to underperformance. Partly based on management's belief that rising interest rates would create a difficult environment for financial services, the Fund maintained small allocations to both the Financial Services Trust and the Real Estate Fund. Entering into the early summer equity market correction, the Fund significantly reduced its allocation to high beta and small-cap sensitive funds. (Beta is a measure of price volatility relative to the broad market's movements. The higher the beta, the more volatile a stock's or fund's price movement.) Specifically, the Fund reduced its allocation to technology-oriented funds such as the Nasdaq-100 Index Fund and the small-cap Special Growth Fund. The proceeds from the sales of market-sensitive funds were held in cash for the duration of the volatile summer period. As markets began to recover, the Fund reinvested its cash across a wide range of underlying funds. Over the latter half of the period, the Fund began to assume a less aggressive market posture and reallocated to more defensive sectors and funds. Although the Fund maintained a clear bias toward equities over the period, the Fund began gradually to increase its investments in both the Convertible Securities Trust and the U.S. Government Securities Trust. Based on the belief that the seven-year period of small- and mid-cap outperformance was approaching an end, the Fund gradually reduced its exposure to small- and mid-cap funds during the year. Specifically, the Fund reduced its allocation to the Special Value Fund, the Special Growth Fund, and the Equally-Weighted S&P 500 Fund. 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.

IN DECIDING HOW TO ALLOCATE FUND ASSETS AMONG UNDERLYING FUNDS, THE FUND'S "INVESTMENT ADVISER," MORGAN STANLEY INVESTMENT ADVISORS INC., CONSIDERS ITS OUTLOOK FOR THE U.S. AND GLOBAL ECONOMIES AND FINANCIAL MARKETS AND THE RELATIVE MARKET VALUATIONS OF THE UNDERLYING FUNDS. THE FUND NORMALLY EXPECTS TO INVEST BETWEEN 50 PERCENT AND 100 PERCENT OF ITS NET ASSETS IN UNDERLYING FUNDS WHICH INVEST PRIMARILY IN U.S. EQUITY SECURITIES, BETWEEN 0 PERCENT AND 50 PERCENT OF ITS NET ASSETS IN UNDERLYING FUNDS WHICH INVEST PRIMARILY IN NON-U.S. EQUITY SECURITIES AND BETWEEN 0 PERCENT AND 50 PERCENT OF ITS NET ASSETS IN UNDERLYING FUNDS WHICH INVEST PRIMARILY IN FIXED INCOME SECURITIES. THE INVESTMENT ADVISER THEN DETERMINES THE COMBINATION OF UNDERLYING FUNDS THAT IT BELIEVES BEST REPRESENTS THE SELECTED ASSET ALLOCATION STRATEGY. THE INVESTMENT ADVISER CONTINUOUSLY MONITORS THE FUND'S ASSET ALLOCATION STRATEGY AND THE SELECTION OF INDIVIDUAL UNDERLYING FUNDS AND MAY MAKE ADJUSTMENTS TO BOTH AS MARKET CHANGES WARRANT. THE FUND GENERALLY SELLS THE SECURITIES OF AN UNDERLYING FUND WHEN SUCH UNDERLYING FUND IS NO LONGER REPRESENTATIVE OF THE SELECTED ASSET ALLOCATION STRATEGY. THERE ARE NO MINIMUM OR MAXIMUM PERCENTAGES IN WHICH THE FUND MUST INVEST IN ANY UNDERLYING FUND. THE INVESTMENT ADVISER FOR EACH UNDERLYING FUND IS RESPONSIBLE FOR DECIDING WHICH SECURITIES TO PURCHASE AND SELL FOR EACH RESPECTIVE UNDERLYING FUND. FOR MORE INFORMATION ABOUT THE UNDERLYING FUNDS, SEE "FUND MANAGEMENT --MANAGEMENT OF THE UNDERLYING FUNDS" IN THE FUND'S PROSPECTUS. IN ADDITION, THE FUND MAY INVEST UP TO 20 PERCENT OF ITS ASSETS DIRECTLY IN GOVERNMENT SECURITIES AND CASH EQUIVALENTS WHEN THE INVESTMENT ADVISER BELIEVES MARKET CONDITIONS SO WARRANT.

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 04/01/06 - 09/30/06. 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 and do not reflect any transactional costs, such as sales charges (loads) and redemption fees. 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. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING PERIOD * ------------- ------------- --------------- 04/01/06 - 04/01/06 09/30/06 09/30/06 ------------- ------------- --------------- CLASS A Actual (-0.67% return) $1,000.00 $ 993.30 $1.25 Hypothetical (5% annual return before expenses) $1,000.00 $1,023.82 $1.27 CLASS B Actual (-0.94% return) $1,000.00 $ 990.60 $4.99 Hypothetical (5% annual return before expenses) $1,000.00 $1,020.05 $5.06 CLASS C Actual (-1.02% return) $1,000.00 $ 989.80 $4.99 Hypothetical (5% annual return before expenses) $1,000.00 $1,020.05 $5.06 CLASS D Actual (-0.50% return) $1,000.00 $ 995.00 $0.00 Hypothetical (5% annual return before expenses) $1,000.00 $1,025.07 $0.00 </Table> - ---------- * EXPENSES ARE EQUAL TO THE FUND'S ANNUALIZED EXPENSE RATIOS OF 0.25%, 1.00%, 1.00% AND 0.00% FOR CLASS A, CLASS B, CLASS C AND CLASS D SHARES, RESPECTIVELY, MULTIPLIED BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY 183/365 (TO REFLECT THE ONE-HALF YEAR PERIOD).

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 Investment 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 advisory and administrative 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 On a regular basis, the Board reviews the performance of all funds in the Morgan Stanley Fund Complex, including the Fund, compared to their peers, paying specific attention to the underperforming funds. In addition, the Board specifically reviewed the Fund's performance for the one-, three- and five-year periods ended November 30, 2005, as shown in a report provided by Lipper (the "Lipper Report"), compared to the performance of comparable funds selected by Lipper (the "performance peer group"). The Board also discussed with the Adviser the performance goals and the actual results achieved in managing the Fund. The Board concluded that the Fund's performance was competitive with that of its performance peer group. FEES RELATIVE TO OTHER PROPRIETARY FUNDS MANAGED BY THE ADVISER WITH COMPARABLE INVESTMENT STRATEGIES The Board noted that the Adviser did not manage any other proprietary funds with investment strategies comparable to those of the Fund. FEES AND EXPENSES RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS The Board reviewed the advisory and administrative fee (together, the "management fee") rate paid by the Fund under the Management Agreement and the total expense ratio of the Fund. The Board noted that the Fund was not 9 <Page> paying any management fee and did not incur expenses, other than brokerage and 12b-1 fees, during the periods measured in the Lipper Report since the Adviser had agreed to waive all fees and assume all expenses, excluding brokerage and 12b-1 fees, until April 30, 2007. The Board concluded that the management fee rate and total expense ratio were satisfactory at the present time. BREAKPOINTS AND ECONOMIES OF SCALE The Board noted that the Adviser does not receive a management fee from the Fund. PROFITABILITY OF THE ADVISER AND AFFILIATES The Board considered information concerning the costs incurred and profits realized by the Adviser and affiliates during the last year from their relationship with the Fund and during the last two years from their relationship with the Morgan Stanley Fund Complex and reviewed with the Adviser the cost allocation methodology used to determine the profitability of the Adviser and affiliates. Based on its review of the information it received, the Board concluded that the profits earned by the Adviser and 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 affiliates from their relationship with the Fund and the Morgan Stanley Fund Complex, such as "float" benefits derived from handling of checks for purchases and sales of Fund shares, through a broker-dealer affiliate of the Adviser. The Board also considered that a broker-dealer affiliate of the Adviser receives from the Fund 12b-1 fees for distribution and shareholder services. The Board concluded that the float benefits were relatively small and the 12b-1 fees were competitive with those of other broker-dealers. 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 other Morgan Stanley funds and 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. 10 <Page> 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 that 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 Multi-Asset Class Fund PORTFOLIO OF INVESTMENTS - SEPTEMBER 30, 2006 <Table> <Caption> NUMBER OF SHARES VALUE - ------------------------------------------------------------------------------------- Common Stocks (95.1%) INVESTMENT TRUSTS/MUTUAL FUNDS 337 Morgan Stanley Aggressive Equity Fund* $ 4,116 182,514 Morgan Stanley Convertible Securities Trust 3,153,837 26,735 Morgan Stanley Developing Growth Securities Trust* 739,497 95,998 Morgan Stanley Dividend Growth Securities Inc. 2,775,294 96 Morgan Stanley Equally-Weighted S&P 500 Fund 4,018 92,890 Morgan Stanley Financial Services Trust 1,408,209 302,401 Morgan Stanley Global Advantage Fund* 3,045,177 88,500 Morgan Stanley Global Utilities Fund 1,505,385 85,322 Morgan Stanley Growth Fund* 1,249,971 99,965 Morgan Stanley Health Sciences Trust* 1,833,353 180,072 Morgan Stanley Technology Fund* 1,838,531 400 Morgan Stanley Japan Fund* 3,744 196,800 Morgan Stanley Limited Duration Fund 1,773,168 197,205 Morgan Stanley Nasdaq-100 Index Fund* 1,873,449 107,870 Morgan Stanley Natural Resource Development Securities Inc. 2,682,738 81,500 Morgan Stanley Real Estate Fund 1,480,044 373,952 Morgan Stanley S&P 500 Index Fund 5,489,616 179 Morgan Stanley Special Growth Fund* 3,605 180 Morgan Stanley Special Value Fund* 3,958 280,558 Morgan Stanley U.

Organization and Accounting Policies Morgan Stanley Multi-Asset Class 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 will invest in Class D shares of other open-end management investment companies that are either members of the Morgan Stanley Family of Funds or managed by an investment advisor that is an affiliate of Morgan Stanley Investment Advisors, Inc. (the "Investment Adviser") (individually, an "Underlying Fund" and collectively, the "Underlying Funds"). The Fund's investment objective is to maximize total investment return. The Fund was organized as a Massachusetts business trust on July 3, 1997 and commenced operations on November 25, 1997. 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 eighteen months, 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) Investments are valued at the net asset value per share of each Underlying Fund determined as of the close of the New York Stock Exchange on valuation date; and (2) 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 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. 17 <Page> 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. 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 Pursuant to an Investment Advisory Agreement, the Fund pays no investment advisory fee. However, the Fund, through its investments in the Underlying Funds, will pay its pro rata share of the advisory or sub-advisory fees to the Investment Adviser and/or Sub-Advisers of the Underlying Funds. Pursuant to an Administration Agreement with Morgan Stanley Services Company Inc. (the "Administrator"), an affiliate of the Investment Adviser, the Fund pays no administration fee. However, the Fund through its investments in the Underlying Funds, will pay its pro rata share of the administration fee to the Administrator. The Investment Adviser agreed to assume all operating expenses (except for distribution fees) until April 30, 2007. At September 30, 2006, included in the Statements of Assets and Liabilities are receivables from an affiliate which represent 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 Adviser and Administrator. 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. 18 <Page> 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 $3,543,551 at September 30, 2006. 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 and other authorized financial representatives at the time of sale may be reimbursed in the subsequent calendar year. For the year ended September 30, 2006, the distribution fee was accrued for Class A shares and Class C shares at the annual rate of 0.24% and 0.97%, respectively. The Distributor has informed the Fund that for the year ended September 30, 2006, it received contingent deferred sales charges from certain redemptions of the Fund's Class A shares, Class B shares and Class C shares of $758, $60,247 and $992, respectively and received $16,183 in front-end sales charges from sales of the Fund's Class A shares. The respective shareholders pay such charges which are not an expense of the Fund. 4. Security Transactions and Transactions with Affiliates The cost of purchases and proceeds from sales of portfolio securities, excluding short-term investments, for the year ended September 30, 2006 aggregated $31,861,144 and $38,441,611, respectively. Morgan Stanley Trust, an affiliate of the Investment Adviser, Administrator and Distributor, is the Funds transfer agent. 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 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 19 <Page> 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. 5. 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. 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: FOR THE YEAR FOR THE YEAR ENDED ENDED SEPTEMBER 30, 2006 SEPTEMBER 30, 2005 ------------------ ------------------ Ordinary income $ 150,643 $119,753 ========== ======== As of September 30, 2006, the tax-basis components of accumulated earnings were as follows: Undistributed ordinary income $ 325,635 Undistributed long-term gains 1,750,578 ---------- Net accumulated earnings 2,076,213 Net unrealized appreciation 1,419,947 ---------- Total accumulated earnings $3,496,160 ========== During the year ended September 30, 2006, the Fund utilized its net capital loss carryforward of $5,710,107. As of September 30, 2006, the Fund had temporary book/tax differences attributable to capital loss deferrals on wash sales and permanent book/tax differences attributable to recharacterization of distributions received from an Underlying Fund. To reflect reclassifications arising from the permanent differences, accumulated undistributed net investment income was charged and accumulated undistributed net realized gain was credited $6,166. 20 <Page> 7.

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, were named as defendants in a consolidated class action. This consolidated action also named as defendants certain individual Trustees and Directors of the Morgan Stanley funds. The consolidated amended complaint, filed in the United States District Court for the Southern District of New York on April 16, 2004, generally alleged 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, 21 <Page> including the Fund, allegedly paid excessive commissions to brokers in return for their alleged efforts to recommend these funds to investors. The complaint sought, among other things, unspecified compensatory damages, rescissionary damages, fees and costs. On July 2, 2004, defendants moved to dismiss the action. On March 9, 2005, plaintiffs filed a Motion for Leave to File a Supplemental Pleading that would, among other things, expand the allegations and alleged class. On April 14, 2006, the Court granted defendants' motion to dismiss in its entirety, with prejudice. Additionally, plaintiffs' Motion for Leave to File a Supplemental Pleading was denied. The time for plaintiffs to appeal the orders granting defendants' motion to dismiss and denying plaintiffs' motion for supplemental pleading has expired. This case is now concluded. 9. 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. 22 <Page> Morgan Stanley Multi-Asset Class 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 SEPTEMBER 30, -------------------------------------------- 2006 2005 2004 2003 2002 ------- ------ ------ ------ ------- Class A Shares Selected Per Share Data: Net asset value, beginning of period $ 11.17 $ 9.80 $ 8.60 $ 6.69 $ 8.17 ------- ------ ------ ------ ------- Income (loss) from investment operations: Net investment income+++ 0.16 0.14 0.06 0.01 0.05 Net realized and unrealized gain (loss) 0.65 1.35 1.14 1.90 (1.45) ------- ------ ------ ------ ------- Total income (loss) from investment operations 0.81 1.49 1.20 1.91 (1.40) ------- ------ ------ ------ ------- Less dividends from net investment income (0.12) (0.12) -- -- (0.08) ------- ------ ------ ------ ------- Net asset value, end of period $ 11.86 $11.17 $ 9.80 $ 8.60 $ 6.69 ======= ====== ====== ====== ======= Total Return+ 7.33% 15.21% 13.95% 28.55% (17.44)% Ratios to Average Net Assets(1)(2)(3): Total expenses (before expense offset) 0.24% 0.24% 0.24% 0.23% 0.24% Net investment income 1.37% 1.33% 0.72% 0.16% 0.50% Supplemental Data: Net assets, end of period, in thousands $12,609 $8,462 $1,896 $ 890 $ 846 Portfolio turnover rate 88% 12% 46% 87% 163% </Table> - ---------- +++ THE PER SHARE AMOUNTS WERE COMPUTED USING AN AVERAGE NUMBER OF SHARES OUTSTANDING DURING THE PERIOD. + DOES NOT REFLECT THE DEDUCTION OF SALES CHARGE.

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 September 30, 2006, by correspondence with the custodian and brokers. 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 Multi-Asset Class Fund as of September 30, 2006, 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.
