There is no assurance that the Fund will achieve its investment objective. The Fund’s share price and return will fluctuate with changes in the market value of the Fund’s portfolio securities. When you sell Fund shares, they may be worth less than what you paid for them and, accordingly, you can lose money investing in this Fund.

A principal risk of investing in the Fund is associated with its common stock investments. In general, stock values fluctuate in response to activities specific to the company, as well as general market, economic and political conditions. Stock prices can fluctuate widely in response to these factors.

Another risk of investing in the Fund arises from its operation as a ‘‘passively’’ managed index fund. As such, the adverse performance of a particular stock ordinarily will not result in the elimination of the stock from the Fund’s portfolio. The Fund will remain invested in common stocks even when stock prices are generally falling. Ordinarily, the Investment Adviser will not sell the Fund’s portfolio securities except to reflect additions or deletions of the stocks that comprise the S&P 500 Index, or as may be necessary to raise cash to pay Fund shareholders who sell Fund shares.

The performance of the S&P 500 Index is a hypothetical number which does not take into account brokerage commissions and other transaction costs, custody and other costs which will be borne by the Fund (e.g., management fee, and transfer agency and accounting costs).

The Fund’s ability to correlate its performance, before expenses, with the S&P 500 Index may be affected by, among other things, changes in securities markets, the manner in which the S&P 500 Index is calculated and the timing of purchases and sales. The Fund’s ability to correlate its performance to the S&P 500 Index also depends to some extent on the size of the Fund’s portfolio, the size of cash flows into and out of the Fund and differences between how and when the Fund and the Index are valued. The Investment Adviser regularly monitors the correlation and, in the event the desired correlation is not achieved, the Investment Adviser will determine what additional investment changes may need to be made.

The performance of the Fund also will depend on whether or not the Investment Adviser is successful in pursuing the Fund’s investment strategy, including the Investment Adviser’s ability to manage cash flows (primarily from purchases and sales, and distributions from the Fund’s investments). The Fund is also subject to other risks from its other permissible investments, including risks associated with stock index futures, SPDRs and foreign securities. For more information about these risks, see the ‘‘Additional Risk Information’’ section.

Shares of the Fund are not bank deposits and are not guaranteed or insured by the FDIC or any other government agency.

The bar chart and table below provide some indication of the risks of investing in the Fund. The Fund’s past performance (before and after taxes) does not indicate how the Fund will perform in the future.

Annual Total Returns—Calendar Years

During the periods shown in the bar chart, the highest return for a calendar quarter was 21.06% (quarter ended December 31, 1998) and the lowest return for a calendar quarter was −17.47% (quarter ended September 30, 2002).

Annual Total Returns

Average Annual Total Returns

Average Annual Total Returns (as of December 31, 2006)

Included in the table above are the after-tax returns for the Fund’s Class B shares. The after-tax returns for the Fund’s other Classes will vary from the Class B shares’ returns. After-tax returns are calculated using the historical highest individual federal marginal income tax rates during the period shown and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns may be higher than before-tax returns due to foreign tax credits and/or an assumed benefit from capital losses that would have been realized had Fund shares been sold at the end of the relevant periods, as applicable.

The table below briefly describes the fees and expenses that you may pay if you buy and hold shares of the Fund. The Fund offers four classes of shares: Classes A, B, C and D. Each Class has a different combination of fees, expenses and other features, which should be considered in selecting a Class of shares. The Fund does not charge account or exchange fees. However, certain shareholders may be charged an order processing fee by the broker-dealer through which shares are purchased, as described below. See the ‘‘Share Class Arrangements’’ section for further fee and expense information.

Shareholder Fees

Annual Fund Operating Expenses

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the Fund, your investment has a 5% return each year and the Fund’s operating expenses remain the same (except for ten-year amounts for Class B shares which reflect the conversion to Class A shares eight years after the end of the calendar month in which shares were purchased). Although your actual costs may be higher or lower, the tables below show your costs at the end of each period based on these assumptions, depending upon whether or not you sell your shares at the end of each period.

Shareholder Fees

Annual Fund
Operating Expenses

While Class B and Class C shares do not have any front-end sales charges, their higher ongoing annual expenses (due to higher 12b-1 fees) mean that over time you could end up paying more for these shares than if you were to pay front-end sales charges for Class A shares.

Order Processing Fees.Your financial intermediary may charge processing or other fees in connection with the purchase or sale of the Fund’s shares. For example, Morgan Stanley & Co. Incorporated (‘‘Morgan Stanley & Co.’’) charges clients an order processing fee of $5.25 (except in certain circumstances, including, but not limited to, activity in fee-based accounts, exchanges, dividend reinvestments and systematic investment and withdrawal plans) when a client buys or redeems shares of the Fund. Please consult your financial representative for more information regarding any such fees.

This section provides additional information relating to the Fund’s investment strategies.

Stock Index Futures. The Fund may invest in stock index futures with respect to the S&P 500 Index. Stock index futures may be used to simulate investment in the S&P 500 Index while retaining a cash balance for fund management purposes, to facilitate trading, to reduce transaction costs or to seek higher investment returns.

SPDRs. The Fund may invest in securities referred to as SPDRs (known as ‘‘spiders’’) that are designed to track the S&P 500 Index. SPDRs represent an ownership interest in the SPDR Trust, which holds a portfolio of common stocks that closely tracks the price performance and dividend yield of the S&P 500 Index. SPDRs trade on the American Stock Exchange like shares of common stock.

* * *

The percentage limitations relating to the composition of the Fund’s portfolio apply at the time the Fund acquires an investment. Subsequent percentage changes that result from market fluctuations generally will not require the Fund to sell any portfolio security. However, the Fund may be required to sell its illiquid securities holdings, or reduce its borrowings, if any, in response to fluctuations in the value of such holdings. The Fund may change its principal investment strategies without shareholder approval; however, you would be notified of any changes.

This section provides additional information relating to the risks of investing in the Fund.

Foreign Securities. The Fund’s investments in the common stocks of foreign corporations (including American Depositary Receipts) may involve risks in addition to the risks associated with domestic securities. Foreign securities are affected by changes in currency rates. Foreign securities also have risks related to political and economic developments abroad. Foreign companies, in general, are not subject to the regulatory requirements of U.S. companies and, as such, there may be less publicly available information about these companies. Moreover, foreign accounting, auditing and financial reporting standards generally are different from those applicable to U.S. companies.

The foreign securities in which the Fund may invest may be issued by companies located in emerging market or developing countries. Compared to the United States and other developed countries, emerging market or developing countries may have relatively unstable governments, economies based on only a few industries and securities markets that trade a small number of securities. Securities issued by companies located in these countries tend to be especially volatile and may be less liquid than securities traded in developed countries. In the past, securities in these countries have been characterized by greater potential loss than securities of companies located in developed countries.

Morgan Stanley
Investment Advisors Inc.

SPDRs. SPDRs, which the Fund may hold, have many of the same risks as direct investments in common stocks. The market value of SPDRs is expected to rise and fall as the S&P 500 Index rises and falls. If the Fund invests in SPDRs, it would, in addition to its own expenses, indirectly bear its ratable share of the SPDR’s expenses.

A description of the Fund’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information.

    The Fund has retained the Investment Adviser—Morgan Stanley Investment Advisors Inc.—to provide investment advisory services. The Investment Adviser is a wholly-owned subsidiary of Morgan Stanley, a preeminent global financial services firm engaged in securities trading and brokerage activities, as well as providing investment banking, research and analysis, financing and financial advisory services. The Investment Adviser’s address is 522 Fifth Avenue, New York, NY 10036.

The Fund is managed within the Systematic Strategies team. The team consists of portfolio managers and analysts. Current members of the team jointly and primarily responsible for the day-to-day management of the Fund’s portfolio are Hooman Yaghoobi, an Executive Director of the Investment Adviser, and Teimur Abasov and Thomas H. Moore, each a Vice President of the Investment Adviser. Mr. Yaghoobi has been associated with the Investment Adviser in an investment management capacity since July 1995 and began managing the Fund in October 2007. Mr. Abasov has been associated with the Investment Adviser in an investment management capacity since March 2005 and began managing the Fund in October 2007. Prior to March 2005, Mr. Abasov worked as a professor at the University of California, Irvine. Mr. Moore has been associated with the Investment Adviser in an investment management capacity since August 1999 and began managing the Fund in April 2006.

Members of the team collaborate to manage the assets of the Fund and are responsible for the execution of the overall strategy of the Fund.

The composition of the team may change from time to time.

The Fund pays the Investment Adviser a monthly advisory fee as full compensation for the services and facilities furnished to the Fund, and for Fund expenses assumed by the Investment Adviser. The fee is based on the Fund’s average daily net assets. For the fiscal year ended August 31, 2007, the Fund accrued total compensation to the Investment Adviser amounting to 0.12% of the Fund’s average daily net assets.

A discussion regarding the Board of Trustees’ approval of the investment advisory agreement is available in the Fund’s annual report to shareholders for the period ended August 31, 2007.

You may open a new account to buy Fund shares or buy additional Fund shares for an existing account by contacting your Morgan Stanley Financial Advisor or other authorized financial representative. Your Financial Advisor will assist you, step-by-step, with the procedures to invest in the Fund. The Fund’s transfer agent, Morgan Stanley Trust (‘‘Transfer Agent’’), in its sole discretion, may allow you to purchase shares directly by calling and requesting an application.

To help the government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify and record information that identifies each person who opens an account. What this means to you: when you open an account, we will ask your name, address, date of birth, and other information that will allow us to identify you. If we are unable to verify your identity, we reserve the right to restrict additional transactions and/or liquidate your account at the next calculated net asset value after your account is closed (less any applicable sales/account charges and/or tax penalties) or take any other action required by law. In accordance with federal law requirements, the Fund has implemented an anti-money laundering compliance program, which includes designation of an anti-money laundering compliance officer.

Because every investor has different immediate financial needs and long-term investment goals, the Fund offers investors four Classes of shares: Classes A, B, C and D. Class D shares are only offered to a limited group of investors. Each Class of shares offers a distinct structure of sales charges, distribution and service fees, and other features that are designed to address a variety of needs. Your Morgan Stanley Financial Advisor or other authorized financial representative can help you decide which Class may be most appropriate for you. When purchasing Fund shares, you must specify which Class of shares you wish to purchase.

When you buy Fund shares, the shares are purchased at the next share price calculated (plus any applicable front-end sales charge for Class A shares) after we receive your purchase order. Your payment is due on the third business day after you place your purchase order. The Fund, in its sole discretion, may waive the minimum initial and additional investment amounts in certain cases. We reserve the right to reject any order for the purchase of Fund shares for any reason.

Order Processing Fees.Your financial intermediary may charge processing or other fees in connection with the purchase or sale of the Fund’s shares. For example, Morgan Stanley & Co. charges clients an order processing fee of $5.25 (except in certain circumstances, including, but not limited to, activity in fee-based accounts, exchanges, dividend reinvestments and systematic investment and withdrawal plans) when a client buys or redeems shares of the Fund. Please consult your financial representative for more information regarding any such fees.

Minimum Investment Amounts

There is no minimum investment amount if you purchase Fund shares through: (1) the Investment Adviser’s mutual fund asset allocation program; (2) a program, approved by the Fund’s distributor, in which you pay an asset-based fee for advisory, administrative and/or brokerage services; (3) the following programs approved by the Fund’s distributor: (i) qualified state tuition plans described in Section 529 of the Internal Revenue Code or (ii) certain other investment programs that do not charge an asset-based fee; (4) employer-sponsored employee benefit plan accounts; (5) certain deferred compensation programs established by the Investment Adviser or its affiliates for their employees or the Fund’s Trustees; or (6) the reinvestment of dividends in additional Fund shares.

Investment Options for Certain Institutional and Other Investors/Class D Shares.

To be eligible to purchase Class D shares, you must qualify under one of the investor categories specified in the ‘‘Share Class Arrangements’’ section of this Prospectus.

Subsequent Investments Sent Directly to the Fund. In addition to buying additional Fund shares for an existing account by contacting your Morgan Stanley Financial Advisor, you may send a check directly to the Fund. To buy additional shares in this manner:

Permissible Fund Exchanges. You may exchange shares of any Class of the Fund for the same Class of any other continuously offered Multi-Class Fund, or for shares of a No-Load Fund, a Money Market Fund or the Limited Duration U.S. Government Trust, without the imposition of an exchange fee. Front-end sales charges are not imposed on

The current prospectus for each Morgan Stanley Fund describes its investment objective(s), policies and investment minimums, and should be read before investment. Since exchanges are available only into continuously offered Morgan Stanley Funds, exchanges are not available into any new Morgan Stanley Fund during its initial offering period, or when shares of a particular Morgan Stanley Fund are not being offered for purchase. An exchange of Fund shares held for less than seven days from the date of purchase will be subject to the 2% redemption fee described under the section ‘‘How to Sell Shares.’’

Exchange Procedures. You can process an exchange by contacting your Morgan Stanley Financial Advisor or other authorized financial representative. You may also write the Transfer Agent or call toll-free (800) 869-NEWS to place an exchange order. If you hold share certificates, no exchanges may be processed until we have received all applicable share certificates.

An exchange to any Morgan Stanley Fund (except a Money Market Fund) is made on the basis of the next calculated net asset values of the funds involved after the exchange instructions, as described above, are received. When exchanging into a Money Market Fund, the Fund’s shares are sold at their next calculated net asset value and the Money Market Fund’s shares are purchased at their net asset value on the following business day.

The Fund may terminate or revise the exchange privilege upon required notice or in certain cases without notice. See ‘‘Limitations on Exchanges.’’ The check writing privilege is not available for Money Market Fund shares you acquire in an exchange.

Telephone Exchanges. For your protection when calling the Transfer Agent, we will employ reasonable procedures to confirm that exchange instructions communicated over the telephone are genuine. These procedures may include requiring various forms of personal identification such as name, mailing address, social security or other tax identification number. Telephone instructions also may be recorded.

Telephone instructions will be accepted if received by the Transfer Agent between 9:00 a.m. and 4:00 p.m. Eastern time on any day the New York Stock Exchange is open for business. During periods of drastic economic or market changes, it is possible that the telephone exchange procedures may be difficult to implement, although this has not been the case with the Fund in the past.

Margin Accounts. If you have pledged your Fund shares in a margin account, contact your Morgan Stanley Financial Advisor or other authorized financial representative regarding restrictions on the exchange of such shares.

Tax Considerations of Exchanges. If you exchange shares of the Fund for shares of another Morgan Stanley Fund, there are important tax considerations. For tax purposes, the exchange out of the Fund is considered a sale of the Fund’s shares—and the exchange into the other fund is considered a purchase. As a result, you may realize a capital gain or loss.

Limitations on Exchanges. Certain patterns of past exchanges and/or purchase or sale transactions involving the Fund or other Morgan Stanley Funds may result in the Fund rejecting, limiting or prohibiting, at its sole discretion, and without prior notice, additional purchases and/or exchanges and may result in a shareholder’s account being closed. Determinations in this regard may be made based on the frequency or dollar amount of the previous exchanges or purchase or sale transactions. The Fund reserves the right to reject an exchange request for any reason.

CDSC Calculations on Exchanges. See the ‘‘Share Class Arrangements’’ section of this Prospectus for a discussion of how applicable contingent deferred sales charges (CDSCs) are calculated for shares of one Morgan Stanley Fund that are exchanged for shares of another.

For further information regarding exchange privileges, you should contact your Morgan Stanley Financial Advisor or call toll-free (800) 869-NEWS.

You can sell some or all of your Fund shares at any time. If you sell Class A, Class B or Class C shares, your net sale proceeds are reduced by the amount of any applicable CDSC. Your shares will be sold at the next price calculated after we receive your order to sell as described below.

Payment for Sold Shares. After we receive your complete instructions to sell as described above, a check will be mailed to you within seven days, although we will attempt to make payment within one business day. Payment may also be sent to your brokerage account.

Payment may be postponed or the right to sell your shares suspended under unusual circumstances as permitted by law. If you request to sell shares that were recently purchased by check, the proceeds of that sale may not be sent to you until it has been verified that the check has cleared, which may take up to 15 calendar days from the date of purchase.

Payments-in-Kind.If we determine that it is in the best interest of other shareholders not to pay redemption proceeds in cash, we may pay you partly or entirely by distributing to you readily marketable securities held by the Fund from which you are redeeming. You may incur brokerage charges and capital gains when you sell those securities.

Order Processing Fee.Your financial intermediary may charge processing or other fees in connection with the purchase or sale of the Fund’s shares. For example, Morgan Stanley & Co. charges clients an order processing fee of $5.25 (except in certain circumstances, including, but not limited to, activity in fee-based accounts, exchanges, dividend reinvestments and systematic investment and withdrawal plans) when a client buys or redeems shares of the Fund. Please consult your financial representative for more information regarding any such fees.

Tax Considerations. Normally, your sale of Fund shares is subject to federal and state income tax. You should review the ‘‘Tax Consequences’’ section of this Prospectus and consult your own tax professional about the tax consequences of a sale.

Reinstatement Privilege. If you sell Fund shares and have not previously exercised the reinstatement privilege, you may, within 35 days after the date of sale, invest any portion of the proceeds in the same Class of Fund shares at their net asset value and receive a pro rata credit for any CDSC paid in connection with the sale.

Involuntary Sales. The Fund reserves the right, on 60 days’ notice, to sell the shares of any shareholder (other than shares held in an individual retirement account (‘‘IRA’’) or 403(b) Custodial Account) whose shares, due to sales by the shareholder, have a value below $100, or in the case of an account opened through EasyInvest^®, if after 12 months the shareholder has invested less than $1,000 in the account.

Margin Accounts. If you have pledged your Fund shares in a margin account, contact your Morgan Stanley Financial Advisor or other authorized financial representative regarding restrictions on the sale of such shares.

Redemption Fee.Fund shares redeemed within seven days of purchase will be subject to a 2% redemption fee, payable to the Fund. The redemption fee is designed to protect the Fund and its remaining shareholders from the effects of short-term trading. The redemption fee is not imposed on redemptions made: (i) through systematic withdrawal/exchange plans, (ii) through pre-approved asset allocation programs, (iii) of shares received by reinvesting income dividends or capital gain distributions, (iv) through certain collective trust funds or other pooled vehicles and (v) on behalf of advisory accounts where client allocations are solely at the discretion of the Morgan Stanley Investment Management investment team. The redemption fee is based on, and deducted from, the redemption proceeds. Each time you redeem or exchange shares, the shares held the longest will be redeemed or exchanged first.

The redemption fee may not be imposed on transactions that occur through certain omnibus accounts at financial intermediaries. Certain financial intermediaries may apply different methodologies than those described above in assessing redemption fees, may impose their own redemption fee that may differ from the Fund’s redemption fee or may impose certain trading restrictions to deter market-timing and frequent trading. If you invest in the Fund through a financial intermediary, please read that financial intermediary’s materials carefully to learn about any other restrictions or fees that may apply.

The Fund passes substantially all of its earnings from income and capital gains along to its investors as ‘‘distributions.’’ The Fund earns income from stocks and interest from temporary investments. These amounts are passed along to Fund shareholders as ‘‘income dividend distributions.’’ The Fund realizes capital gains whenever it sells securities for a higher price than it paid for them. These amounts may be passed along as ‘‘capital gain distributions.’’

The Fund declares income dividends separately for each Class. Distributions paid on Class A and Class D shares usually will be higher than for Class B and Class C shares because distribution fees that Class B and Class C shares pay are higher. Normally, income dividends are distributed to shareholders annually. Capital gains, if any, are usually distributed in December. The Fund, however, may retain and reinvest any long-term capital gains. The Fund may at times make

Targeted Dividends^SM

Distributions are reinvested automatically in additional shares of the same Class and automatically credited to your account, unless you request in writing that all distributions be paid in cash. If you elect the cash option, the Fund will mail a check to you no later than seven business days after the distribution is declared. However, if you purchase Fund shares through a Morgan Stanley Financial Advisor or other authorized financial representative within three business days prior to the record date for the distribution, the distribution will automatically be paid to you in cash, even if you did not request to receive all distributions in cash. No interest will accrue on uncashed checks. If you wish to change how your distributions are paid, your request should be received by the Transfer Agent at least five business days prior to the record date of the distributions.

Frequent purchases and redemptions of Fund shares by Fund shareholders are referred to as ‘‘market-timing’’ or ‘‘short-term trading’’ and may present risks for other shareholders of the Fund, which may include, among other things, dilution in the value of Fund shares held by long-term shareholders, interference with the efficient management of the Fund’s portfolio, increased brokerage and administrative costs, incurring unwanted taxable gains and forcing the Fund to hold excess levels of cash.

In addition, the Fund is subject to the risk that market-timers and/or short-term traders may take advantage of time zone differences between the foreign markets on which the Fund’s portfolio securities trade and the time as of which the Fund’s net asset value is calculated (‘‘time-zone arbitrage’’). For example, a market-timer may purchase shares of the Fund based on events occurring after foreign market closing prices are established, but before the Fund’s net asset value calculation, that are likely to result in higher prices in foreign markets the following day. The market-timer would redeem the Fund’s shares the next day when the Fund’s share price would reflect the increased prices in foreign markets, for a quick profit at the expense of long-term Fund shareholders.

The Fund’s policies with respect to valuing portfolio securities are described in ‘‘Shareholder Information—Pricing Fund Shares.’’

The Fund discourages and does not accommodate frequent purchases and redemptions of Fund shares by Fund shareholders and the Fund’s Board of Trustees has adopted policies and procedures with respect to such frequent purchases and redemptions. The Fund’s policies with respect to purchases, redemptions and exchanges of Fund shares are described in the ‘‘How to Buy Shares,’’ ‘‘How to Exchange Shares’’ and ‘‘How to Sell Shares’’ sections of this Prospectus. Except as described in each of these sections, and with respect to trades that occur through omnibus accounts at intermediaries, as described below, the Fund’s policies regarding frequent trading of Fund shares are applied uniformly to all shareholders. With respect to trades that occur through omnibus accounts at intermediaries, such as investment managers, broker-dealers, transfer agents and third party administrators, the Fund (i) has requested assurance that such intermediaries currently selling Fund shares have in place internal policies and procedures reasonably designed to address market-timing concerns and has instructed such intermediaries to notify the Fund immediately if they are unable to comply with such policies and procedures and

Omnibus accounts generally do not identify customers’ trading activity to the Fund on an individual ongoing basis. Therefore, with respect to trades that occur through omnibus accounts at financial intermediaries, to some extent, the Fund relies on the financial intermediary to monitor frequent short-term trading within the Fund by the financial intermediary’s customers. However, the Fund or the distributor has entered into agreements with financial intermediaries whereby intermediaries are required to provide certain customer identification and transaction information upon the Fund’s request. The Fund may use this information to help identify and prevent market-timing activity in the Fund. There can be no assurance that the Fund will be able to identify or prevent all market-timing activities.

As with any investment, you should consider how your Fund investment will be taxed. The tax information in this Prospectus is provided as general information. You should consult your own tax professional about the tax consequences of an investment in the Fund.

Unless your investment in the Fund is through a tax-deferred retirement account, such as a 401(k) plan or IRA, you need to be aware of the possible tax consequences when:

Taxes on Distributions. Your distributions are normally subject to federal and state income tax when they are paid, whether you take them in cash or reinvest them in Fund shares. A distribution also may be subject to local income tax. Any income dividend distributions and any short-term capital gain distributions are taxable to you as ordinary income. Any long-term capital gain distributions are taxable as long-term capital gains, no matter how long you have owned shares in the Fund. Under current law, a portion of the income dividends you receive may be taxed at the same rate as long-term capital gains. However, even if income received in the form of income dividends is taxed at the same rates as long-term capital gains, such income will not be considered long-term capital gains for other federal income tax purposes. For example, you generally will not be permitted to offset income dividends with capital losses. Short-term capital gain distributions will continue to be taxed at ordinary income rates.

Every January, you will be sent a statement (IRS Form 1099-DIV) showing the taxable distributions paid to you in the previous year. The statement provides information on your dividends and capital gains for tax purposes.

Taxes on Sales. Your sale of Fund shares normally is subject to federal and state income tax and may result in a taxable gain or loss to you. A sale also may be subject to local income tax. Your exchange of Fund shares for shares of another Morgan Stanley Fund is treated for tax purposes like a sale of your original shares and a purchase of your new shares. Thus, the exchange may, like a sale, result in a taxable gain or loss to you and will give you a new tax basis for your new shares.

The Fund offers several Classes of shares having different distribution arrangements designed to provide you with different purchase options according to your investment needs. Your Morgan Stanley Financial Advisor or other authorized financial representative can help you decide which Class may be appropriate for you.

The general public is offered three Classes: Class A shares, Class B shares and Class C shares, which differ principally in terms of sales charges and ongoing expenses. A fourth Class, Class D shares, is offered only to a limited category of investors. Shares that you acquire through reinvested distributions will not be subject to any front-end sales charge or CDSC.

Sales personnel may receive different compensation for selling each Class of shares. The sales charges applicable to each Class provide for the distribution financing of shares of that Class.

The chart below compares the sales charge and the annual 12b-1 fees applicable to each Class:

Certain shareholders may be eligible for reduced sales charges (i.e., breakpoint discounts), CDSC waivers and eligibility minimums. Please see the information for each Class set forth below for specific eligibility requirements. You must notify your Morgan Stanley Financial Advisor or other authorized financial representative (or the Transfer Agent if you purchase shares directly through the Fund) at the time a purchase order (or in the case of Class B or Class C shares, a redemption order) is placed, that the purchase (or redemption) qualifies for a reduced sales charge (i.e., breakpoint discount), CDSC waiver or eligibility minimum. Similar notification must be made in writing when an order is placed by mail. The reduced sales charge, CDSC waiver or eligibility minimum will not be granted if: (i) notification is not furnished at the time of order; or (ii) a review of the records of Morgan Stanley & Co. or other authorized dealer of Fund shares, or the Transfer Agent does not confirm your represented holdings.

In order to obtain a reduced sales charge (i.e., breakpoint discount) or to meet an eligibility minimum, it may be necessary at the time of purchase for you to inform your Morgan Stanley Financial Advisor or other authorized financial representative (or the Transfer Agent if you purchase shares directly through the Fund) of the existence of other accounts in which there are holdings eligible to be aggregated to meet the sales load breakpoints or eligibility

Class A Shares Class A shares are sold at net asset value plus an initial sales charge of up to 5.25% of the public offering price. The initial sales charge is reduced for purchases of $25,000 or more according to the schedule below. Investments of $1 million or more are not subject to an initial sales charge, but are generally subject to a CDSC of 1.00% on sales made within 18 months after the last day of the month of purchase. The CDSC will be assessed in the same manner and with the same CDSC waivers as with Class B shares. In addition, the CDSC on Class A shares will be waived in connection with sales of Class A shares for which no commission or transaction fee was paid by the distributor to authorized dealers at the time of purchase of such shares. Class A shares are also subject to a distribution and shareholder services (12b-1) fee of up to 0.25% of the average daily net assets of the Class. The maximum annual 12b-1 fee payable by Class A shares is lower than the maximum annual 12b-1 fee payable by Class B or Class C shares.

The offering price of Class A shares includes a sales charge (expressed as a percentage of the public offering price) on a single transaction as shown in the following table:

You may benefit from a reduced sales charge schedule (i.e., breakpoint discount) for purchases of Class A shares of the Fund, by combining, in a single transaction, your purchase with purchases of Class A shares of the Fund by the following related accounts:

Front-End Sales
Charge or FSC

Combined Purchase Privilege. You will have the benefit of reduced sales charges by combining purchases of Class A shares of the Fund for any related account in a single transaction with purchases of any class of shares of other Morgan Stanley Multi-Class Funds for the related account or any other related account. For the purpose of this combined purchase privilege, a ‘‘related account’’ is:

Right of Accumulation.You may benefit from a reduced sales charge if the cumulative net asset value of Class A shares of the Fund purchased in a single transaction, together with the net asset value of all classes of shares of Morgan Stanley Multi-Class Funds (including shares of Morgan Stanley Non-Multi-Class Funds which resulted from an exchange from Morgan Stanley Multi-Class Funds) held in related accounts, amounts to $25,000 or more. For the purposes of the right of accumulation privilege, a related account is any one of the accounts listed under ‘‘Combined Purchase Privilege’’ above.

Notification.You must notify your Morgan Stanley Financial Advisor or other authorized financial representative (or the Transfer Agent if you purchase shares directly through the Fund) at the time a purchase order is placed that the purchase qualifies for a reduced sales charge under any of the privileges discussed above. Similar notification must be made in writing when an order is placed by mail. The reduced sales charge will not be granted if: (i) notification is not furnished at the time of the order; or (ii) a review of the records of Morgan Stanley & Co. or other authorized dealer of Fund shares or the Transfer Agent does not confirm your represented holdings.

In order to obtain a reduced sales charge under any of the privileges discussed above, it may be necessary at the time of purchase for you to inform your Morgan Stanley Financial Advisor or other authorized financial representative (or the Transfer Agent if you purchase shares directly through the Fund) of the existence of other accounts in which there are holdings eligible to be aggregated to meet the sales load breakpoint and/or right of accumulation threshold. In order to verify your eligibility, you may be required to provide account statements and/or confirmations regarding shares of the Fund or other Morgan Stanley Funds held in all related accounts described above at Morgan Stanley or by other authorized dealers, as well as shares held by related parties, such as members of the same family or household, in order to determine whether you have met the sales load breakpoint and/or right of accumulation threshold. The Fund makes available, in a clear and prominent format, free of charge,

Letter of Intent. The above schedule of reduced sales charges for larger purchases also will be available to you if you enter into a written ‘‘Letter of Intent.’’ A Letter of Intent provides for the purchase of Class A shares of the Fund or other Multi-Class Funds within a 13-month period. The initial purchase under a Letter of Intent must be at least 5% of the stated investment goal. The Letter of Intent does not preclude the Fund (or any other Multi-Class Fund) from discontinuing sales of its shares. To determine the applicable sales charge reduction, you may also include: (1) the cost of shares of other Morgan Stanley Funds which were previously purchased at a price including a front-end sales charge during the 90-day period prior to the distributor receiving the Letter of Intent, and (2) the historical cost of shares of other funds you currently own acquired in exchange for shares of funds purchased during that period at a price including a front-end sales charge. You may combine purchases and exchanges by family members (limited to spouse, and to children under the age of 21) during the periods referenced in (1) and (2) above. You should retain any records necessary to substantiate historical costs because the Fund, the Transfer Agent and any financial intermediaries may not maintain this information. You can obtain a Letter of Intent by contacting your Morgan Stanley Financial Advisor or other authorized financial representative, or by calling toll-free (800) 869-NEWS. If you do not achieve the stated investment goal within the 13-month period, you are required to pay the difference between the sales charges otherwise applicable and sales charges actually paid, which may be deducted from your investment. Shares acquired through reinvestment of distributions are not aggregated to achieve the stated investment goal.

Other Sales Charge Waivers. In addition to investments of $1 million or more, your purchase of Class A shares is not subject to a front-end sales charge (or a CDSC upon sale) if your account qualifies under one of the following categories:

Contingent Deferred Sales Charge or CDSC

Class B Shares Class B shares are offered at net asset value with no initial sales charge but are subject to a CDSC, as set forth in the table below. For the purpose of calculating the CDSC, shares are deemed to have been purchased on the last day of the month during which they were purchased.

The CDSC is assessed on an amount equal to the lesser of the then market value of the shares or the historical cost of the shares (which is the amount actually paid for the shares at the time of original purchase) being redeemed. Accordingly, no sales charge is imposed on increases in net asset value above the initial purchase price. In determining whether a CDSC applies to a redemption, it is assumed that the shares being redeemed first are any shares in the shareholder’s Fund account that are not subject to a CDSC, followed by shares held the longest in the shareholder’s account.

Broker-dealers or other financial intermediaries may impose a limit on the dollar value of a Class B share purchase order that they will accept. You should discuss with your financial advisor which share class is most appropriate for you, based on the size of your investment, your expected time horizon for holding the shares and other factors, bearing in mind the availability of reduced sales loads on Class A share purchases of $25,000 or more and for existing shareholders who hold over $25,000 in Morgan Stanley Funds.

CDSC Waivers. A CDSC, if otherwise applicable, will be waived in the case of:

The Fund’s distributor may require confirmation of your entitlement before granting a CDSC waiver. If you believe you are eligible for a CDSC waiver, please contact your Morgan Stanley Financial Advisor or other authorized financial representative or call toll-free (800) 869-NEWS.

Distribution Fee. Class B shares are also subject to an annual distribution and shareholder services (12b-1) fee of up to 1.00% of the average daily net assets of Class B shares. The maximum annual 12b-1 fee payable by Class B shares is higher than the maximum annual 12b-1 fee payable by Class A shares.

Conversion Feature. After eight years, Class B shares generally will convert automatically to Class A shares of the Fund with no initial sales charge. The eight-year period runs from the last day of the month in which the shares were purchased or, in the case of Class B shares acquired through an exchange, from the last day of the month in which the original Class B shares were purchased; the shares will convert to Class A shares based on their relative net asset values in the month following the eight-year period. At the same time, an equal proportion of Class B shares acquired through automatically reinvested distributions will convert to Class A shares on the same basis. This conversion will be suspended during any period in which the expense ratio of the Class B shares of the Fund is lower than the expense ratio of the Class A shares of the Fund.

In the case of Class B shares held in a Morgan Stanley Eligible Plan, the plan is treated as a single investor and all Class B shares will convert to Class A shares on the conversion date of the Class B shares of a Morgan Stanley Fund purchased by that plan.

Exchanging Shares Subject to a CDSC. There are special considerations when you exchange Fund shares that are subject to a CDSC. When determining the length of time you held the shares and the corresponding CDSC rate, any period (starting at the end of the month) during which you held shares of a fund that does not charge a CDSC will not be counted. Thus, in effect the ‘‘holding period’’ for purposes of calculating the CDSC is frozen upon exchanging into a fund that does not charge a CDSC.

For example, if you held Class B shares of the Fund for one year, exchanged to Class B of another Morgan Stanley Multi-Class Fund for another year, then sold your shares, a CDSC rate of 4% would be imposed on the shares based on a two-year holding period—one year for each fund. However, if you had exchanged the shares of the Fund for a Money Market Fund (which does not charge a CDSC) instead of the Multi-Class Fund, then sold your shares, a CDSC rate of 5% would be imposed on the shares based on a one-year holding period. The one year in the Money Market Fund would not be counted. Nevertheless, if shares subject to a CDSC are exchanged for a fund that does not charge a CDSC, you will receive a credit when you sell the shares equal to the 12b-1 fees, if any, you paid on those shares while in that fund up to the amount of any applicable CDSC.

In addition, shares that are exchanged into or from a Morgan Stanley Fund subject to a higher CDSC rate will be subject to the higher rate, even if the shares are re-exchanged into a fund with a lower CDSC rate.

Class C shares Class C shares are sold at net asset value with no initial sales charge, but are subject to a CDSC of 1.00% on sales made within one year after the last day of the month of purchase. The CDSC will be assessed in the same manner and with the same CDSC waivers as with Class B shares.

Brokers, dealers or other financial intermediaries may impose a limit on the dollar value of a Class C share purchase order that they will accept. For example, a Morgan Stanley Financial Advisor generally will not accept purchase orders for Class C shares that in the aggregate amount to $250,000 or more. You should discuss with your financial advisor which share class is most appropriate for you based on the size of your investment, your expected time horizon for holding the shares and other factors, bearing in mind the availability of reduced sales loads on Class A share purchases of $25,000 or more and for existing shareholders who hold over $25,000 in Morgan Stanley Funds.

Distribution Fee. Class C shares are subject to an annual distribution and shareholder services (12b-1) fee of up to 1.00% of the average daily net assets of that Class. The maximum annual 12b-1 fee payable by Class C shares is higher than the maximum annual 12b-1 fee payable by Class A shares. Unlike Class B shares, Class C shares have no conversion feature and, accordingly, an investor that purchases Class C shares may be subject to distribution and shareholder services (12b-1) fees applicable to Class C shares for as long as the investor owns such shares.

A purchase order that meets the requirements for investment in Class D shares can be made only in Class D shares.

Class D shares are not offered for investments made through Section 529 plans, donor-advised charitable gift funds and insurance company separate accounts (regardless of the size of the investment).

Meeting Class D Eligibility Minimums. To meet the $5 million ($25 million for Morgan Stanley Eligible Plans) initial investment to qualify to purchase Class D shares you may combine: (1) purchases in a single transaction of Class D shares of the Fund and other Morgan Stanley Multi-Class Funds; and/or (2) previous purchases of Class A and Class D shares of Multi-Class Funds you currently own, along with shares of Morgan Stanley Funds you currently own that you acquired in exchange for those shares. Shareholders cannot combine purchases made by family members or a shareholder’s other related accounts in a single transaction for purposes of meeting the $5 million initial investment minimum requirement to qualify to purchase Class D shares.

No Sales Charges for Reinvested Cash Distributions If you receive a cash payment representing an ordinary dividend or capital gain and you reinvest that amount in the applicable Class of shares by returning the check within 30 days of the payment date, the purchased shares would not be subject to an initial sales charge or CDSC.

The Investment Adviser and/or distributor may pay compensation (out of their own funds and not as an expense of the Fund) to certain affiliated or unaffiliated brokers, dealers or other financial intermediaries or service providers in connection with the sale or retention of Fund shares and/or shareholder servicing. Such compensation may be significant in amount and the prospect of receiving any such additional compensation may provide such affiliated or unaffiliated entities with an incentive to favor sales of shares of the Fund over other investment options. Any such payments will not change the net asset value or the price of the Fund’s shares. For more information, please see the Fund’s Statement of Additional Information.
