These risks are likely to be greater in emerging market countries than in countries with developed securities markets and more advanced regulatory regimes. Emerging market countries may have economic structures that are less mature and political systems that are less stable. Moreover, emerging market countries may have less developed securities markets, high inflation, and rapidly changing interest and currency exchange rates.

Some of the foreign securities in which the Fund invests may be denominated in foreign currency. Changes in foreign currency exchange rates will affect the value of securities denominated or quoted in foreign currencies. Exchange rate movements can be large and can endure for extended periods of time, affecting either favorably or unfavorably the value of the Fund 's assets.

Investments in fixed-income securities are subject to the risk that interest rates could rise, causing the value of the Fund 's fixed-income securities and share price to decline. Longer term bonds and zero coupon bonds are generally more sensitive to interest rate changes than shorter term bonds. Generally, the longer the average maturity of the bonds in a fund, the more a fund's share price will fluctuate in response to interest rate changes. Securities with floating interest rates generally are less sensitive to interest rate changes, but may decline in value if their interest rates do not rise as much or as fast as interest rates in general.

Past Performance

The following bar chart and tables indicate some of the risks of investing in the Fund. The bar chart shows how the Fund's performance has varied since inception. The table shows how the Fund's average annual total returns (before and after taxes) for a one year period and since inception compared to those of a broad-based securities market index. Performance figures for Class I shares and Class A shares reflect the historical performance of the Institutional shares and the Class P shares, respectively, each of the Epoch Global Equity Shareholder Yield Fund (a predecessor to the Fund, which was subject to a different fee structure, and for which Epoch served as investment adviser). Absent expense limitations and/or fee waivers/reimbursements that were applicable to the Epoch Global Equity Shareholder Yield Fund, performance would have been lower. As with all mutual funds, past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Class C and Investor Class shares of the Fund have no performance history.

As of June 30, 2009, the Class I shares of the Fund had a year to date return of 1.86%.

Fees and Expenses of the Fund

The table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund. The information in the table is based on expenses incurred by Epoch Global Equity Shareholder Yield Fund (a predecessor to the Fund) as of the fiscal year ended December 31, 2008 and has been been adjusted to reflect certain differences in contractual expenses and fees. It is important for investors to understand that a decline in the average net assets of Epoch Global Equity Shareholder Yield Fund or the Fund during the current fiscal year due to recent market declines or other factors could cause the Fund's expense ratios to be higher than the expense information presented. Please see the footnotes following the table for a discussion of New York Life Investments' agreement to voluntarily reimburse certain expenses for Class A and Class I shares of the Fund.

Example

The 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 for the time periods indicated and reflects what you would pay if you redeemed all your shares at the end of each time period shown or if you continued to hold them. The Example also assumes that your investment has a 5% return each year, that the Fund's operating expenses remain the same, and that all dividends and distributions are reinvested. There is no sales charge (load) on reinvested dividends. Your actual costs may be higher or lower than those shown.

Principal Investment Strategy

The Fund seeks to achieve its investment objective by investing in a diversified portfolio consisting mostly of equity securities of companies located outside the U.S. Under normal circumstances, the Fund will invest at least 80% of its assets in the equity securities of "small capitalization" companies located outside of the U.S. Equity securities consist of common stock, depositary receipts, and securities convertible into common stock, such as warrants, rights, convertible bonds, debentures and convertible preferred stocks. Typically, a company is considered to be a "small capitalization" company if it has, at the time of purchase by the Fund, a market capitalization that is in the bottom 25% of publicly traded companies in each country where the Fund invests. The Fund will normally invest in companies located in at least three countries outside of the United States. A company is considered to be located in a particular country if it: (i) is organized under the laws of the country; (ii) has securities which are principally traded on a stock exchange in the country; (iii) derives at least 50% of its revenues from goods produced or sold, investments made, or services performed in the country; or (iv) maintains at least 50% of its assets in the country. Although the Fund is not subject to any additional geographic requirement, the Fund expects that the majority of its investments will be in the developed markets of Western Europe and Asia. The Fund may invest more than 25% of its assets in securities of companies located in each of the United Kingdom and Japan.

Investment Process

Epoch, the Fund's Subadvisor, utilizes an investment strategy that combines bottom-up stock research and selection with top-down analysis. The Subadvisor seeks securities of companies with solid long-term prospects, attractive valuation comparisons and adequate market liquidity. The stocks the Subadvisor finds attractive generally have valuations lower than the Subadvisor's perception of their fundamental value.

The Subadvisor may sell or reduce a position in a security that otherwise meets its objectives but is deemed less attractive relative to another security on a return/risk basis. The Subadvisor will also sell or reduce a position in a security when it sees the objectives of its investment thesis failing to materialize, or when it believes those objectives have been met and the valuation of the company's shares fully reflect the opportunities once thought unrecognized in the share price. The Subadvisor may believe that objectives are not being met for a number of reasons, such as: the economic or competitive environment might be changing; the company management's execution could be disappointing; or company management has an inappropriate assessment of the company's state and the task at hand.

Principal Risks

Investments in common stocks and other equity securities are particularly subject to the risk of changing economic, stock market, industry and company conditions and the risks inherent in management's ability to anticipate such changes that can adversely affect the value of the Fund's holdings. Opportunities for greater gain often come with the possibility of a greater risk of loss. Some of the securities in which the Fund invests may, therefore, carry above-average risk compared to the risk of securities found in common stock indices such as the Dow Jones Industrial Average and the S&P 500 ^® Index. In addition, different types of stocks tend to shift in and out of favor depending on market and economic conditions and therefore the Fund's performance may be lower or higher than that of funds that invest in other types of equity securities.

The Fund may invest in companies with mid to small market capitalizations. Such stocks are generally less established and may be more volatile and less liquid than stocks of other companies. Smaller capitalization stocks may be more thinly traded than larger company stocks and consequently may be more volatile. The returns may vary significantly from the overall stock market. In comparison to stocks of companies with larger capitalizations, these companies may have more price volatility, greater spreads between their bid and ask prices, significantly lower trading volumes and cyclical, static or moderate growth prospects. Smaller capitalization companies may be more vulnerable to adverse business or market developments than larger-capitalization companies.

Since the Fund invests a significant portion of its assets in foreign securities, which are securities issued by companies organized outside the U.S. and traded in markets outside the U.S., it will be subject to risks that differ from the risks of investing in securities of U.S. issuers.

These risk factors include:

• fluctuating currency values;

• less liquid trading markets;

• greater price volatility;

• political and economic instability;

• less publicly available information about issuers;

• changes in U.S. or foreign tax or currency laws; and

• changes in monetary policy.

Foreign securities may be more difficult to sell than U.S. securities. Investments in foreign securities may involve difficulties in receiving or interpreting financial and economic information, possible imposition of taxes, higher brokerage and custodian fees, possible currency exchange controls or other government restrictions, including possible seizure or nationalization of foreign deposits or assets. Foreign securities may also be less liquid and more volatile than U.S. securities. There may also be difficulty in invoking legal protections across borders. Risks relating to withholding or other taxes, trading, settlement, custodial and other operational risks, and the loss of stringent investor protection and disclosure standards in some foreign markets may cause the Fund 's share price to be more volatile than that of a U.S.-only Fund .

The Fund may also incur higher expenses and costs when making foreign investments, which could affect the Fund 's total return.

Changes affecting particular regions or sectors of international markets may also have a significant impact on the Fund .

These risks are likely to be greater in emerging market countries than in countries with developed securities markets and more advanced regulatory regimes. Emerging market countries may have economic structures that are less mature and political systems that are less stable. Moreover, emerging market countries may have less developed securities markets, high inflation, and rapidly changing interest and currency exchange rates.

Some of the foreign securities in which the Fund invests may be denominated in foreign currency. Changes in foreign currency exchange rates will affect the value of securities denominated or quoted in foreign currencies. Exchange rate movements can be large and can endure for extended periods of time, affecting either favorably or unfavorably the value of the Fund 's assets.

Some of the securities in which the Fund invests may be issued by companies organized outside the U.S. but are traded in U.S. securities markets and are denominated in U.S. dollars. For example, ADRs and shares of some large foreign-based companies are traded on principal U.S. exchanges. Other securities are not traded in the U.S. but are denominated in U.S. dollars. These securities are subject to some but not all of the risks of foreign investing. For example, foreign trading market or currency risks will not apply to dollar denominated securities traded in U.S. securities markets.

Convertible securities tend to be subordinate to other debt securities issued by the same company. The total return for a convertible security will be partly dependent upon performance of the underlying common stock into which it can be converted. Also, issuers of convertible securities are often not as strong financially as those issuing securities with higher credit ratings. These companies are more likely to encounter financial difficulties and are more vulnerable to changes in the economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments. If an issuer stops making interest and/or principal payments, these securities may be worthless and the Fund could lose its entire investment.

The values of a synthetic convertible and a true convertible security may respond differently to market fluctuations. In addition, in purchasing a synthetic convertible security, the Fund may have counterparty (including credit) risk with respect to the financial institution or investment bank that offers the instrument. Purchasing a synthetic convertible security may provide greater flexibility than purchasing a traditional convertible security.

Due to its trading strategies, the Fund may experience a portfolio turnover rate of over 100%. Funds with high turnover rates (over 100%) often have higher transaction costs (which are paid by the Fund) and may generate short-term capital gains (on which you may pay taxes, even if you do not sell any shares by year-end).

Portfolio turnover measures the amount of trading a Fund does during the year.

Past Performance

The following bar chart and tables indicate some of the risks of investing in the Fund. The bar chart shows how the Fund's performance has varied since inception. The table shows how the Fund's average annual total returns (before and after taxes) for a one year period and since inception compared to those of a broad-based securities market index. Performance figures for Class I shares and Class A shares reflect the historical performance of the Institutional shares and the Class P shares, respectively, each of the Epoch International Small Cap Fund (a predecessor to the Fund, which was subject to a different fee structure, and for which Epoch served as investment adviser). Absent expense limitations and/or fee waivers/reimbursements that were applicable to the Epoch International Small Cap Fund, performance would have been lower. As with all mutual funds, past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Class C and Investor Class shares of the Fund have no performance history.

As of June 30, 2009, the Class I shares of the Fund had a year to date return of 16.13%.

Fees and Expenses of the Fund

The table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund. The information in the table is based on expenses incurred by Epoch International Small Cap Fund (a predecessor to the Fund) as of the fiscal year ended December 31, 2008 and has been been adjusted to reflect certain differences in contractual expenses and fees. It is important for investors to understand that a decline in the average net assets of Epoch International Small Cap Fund or the Fund during the current fiscal year due to recent market declines or other factors could cause the Fund's expense ratios to be higher than the expense information presented. Please see the footnotes following the table for a discussion of New York Life Investments' agreement to voluntarily reimburse certain expenses for Class A and Class I shares of the Fund.

There is no sales charge (load) on reinvested dividends. Your actual costs may be higher or lower than those shown.

Additional information about the investment practices of the Funds and risks pertinent to these practices is included in the Statement of Additional Information ("SAI") (see the back cover of this Prospectus).

American Depositary Receipts ("ADRs")

The Fund s may invest in ADRs. ADRs, which are typically issued by a U.S. financial institution (a "depositary"), evidence ownership interests in a security or pool of securities issued by a foreign company which are held by a depositary. ADRs are denominated in U.S. dollars and trade in the U.S. securities markets. Because ADRs are not denominated in the same currency as the underlying securities into which they may be converted, they are subject to currency risks. In addition, depositary receipts involve many of the same risks of investing directly in foreign securities.

Derivative Securities

The Funds may invest in derivative securities, or "derivatives." The value of derivative securities is based on certain underlying equity or fixed-income securities, interest rates, currencies or indices and include options, futures, options on futures and swap agreements. The use of these transactions is a highly specialized activity that involves investment techniques, tax planning and risks that are different from those of ordinary securities transactions. Derivative securities may be hard to sell at an advantageous price or time and typically are very sensitive to changes in the underlying security, interest rate, currency or index. As a result, derivatives can be highly volatile. If the Manager or the Subadvisor is incorrect about its expectations of changes in interest rates or market conditions, the use of derivatives could result in a loss. When using derivatives, there is a risk that a Fund will lose money if the contract counterparty does not make the required payments or otherwise fails to comply with the terms of the contract. In particular, credit default swaps can result in losses if a Fund does not correctly evaluate the creditworthiness of the company on which the credit default is based. Such instruments are not afforded the same protections as may apply to participants trading futures or options on organized exchanges, such as the performance guarantee of an exchange clearinghouse. In the event of the bankruptcy or insolvency of a counterparty, the Fund could experience the loss of some or all of its investment or experience delays in liquidating its positions, including declines in the value of its investment during the period in which the Fund seeks to enforce its rights, and an inability to realize any gains on its investment during such period. A Fund may also incur fees and expenses in enforcing its rights. In addition, the leverage associated with inverse floaters, a type of derivative, may result in greater volatility in their market value than other income-producing securities.

As investment companies registered with the SEC, the Funds must "cover" open positions with respect to certain kinds of derivatives instruments.

Foreign Securities

Generally, foreign securities are issued by companies organized outside the U.S. and are traded in markets outside the U.S. Foreign securities may be more difficult to sell than U.S. securities. Investments in foreign securities may involve difficulties in receiving or interpreting financial and economic information, possible imposition of taxes, higher brokerage and custodian fees, possible currency exchange controls or other government restrictions, including possible seizure or nationalization of foreign deposits or assets. Foreign securities may also be less liquid and more volatile than U.S. securities. There may also be difficulty in invoking legal protections across borders. In addition, investments in emerging market countries present risks to a greater degree than those presented by investments in countries with developed securities markets and more advanced regulatory systems.

Many of the foreign securities in which the Funds invest will be denominated in foreign currency. Changes in foreign currency exchange rates will affect the value of securities denominated or quoted in foreign currencies. Exchange rate movements can be large and can endure for extended periods of time, affecting either favorably or unfavorably the value of the Funds' assets. However, a Fund may engage in foreign currency transactions to attempt to protect itself against fluctuations in currency exchange rates in relation to the U.S. dollar. See "Risk Management Techniques" below.

Illiquid and Restricted Securities

A Fund's investments may include illiquid securities or restricted securities. The principal risk of investing in illiquid and restricted securities is that they may be difficult to sell. Restricted securities are securities that are sold only through negotiated private transactions and not to the general public, due to certain restrictions imposed by federal securities laws. Illiquid securities are securities that have no ready market.

Initial Public Offerings

The Funds may invest in securities that are made available in initial public offerings ("IPOs"). IPO securities may be volatile, and the Funds cannot predict whether investments in IPOs will be successful. As a Fund grows in size, the positive effect of IPO investments on the Fund may decrease.

Investment Policies and Objectives

For some of the Funds, the discussion of Principal Investment Strategy states that the relevant Fund normally invests at least 80% of its assets in a particular type of investment. For these purposes "assets" means the Fund's net assets plus any borrowings for investment purposes. Under normal circumstances, the 80% requirement must be complied with at the time the Fund invests its assets. A Fund that, under normal circumstances, no longer meets the 80% requirement as a result of circumstances beyond its control, such as changes in the value of portfolio holdings, would not have to sell its holdings but would have to make any new investments in such a way as to bring the portfolio more into compliance with the 80% requirement. Where other than normal circumstances exist, a Fund would not be subject to such constraints on new investments.

When the discussion states that a Fund invests primarily in a certain type or style of investment, this means that under normal circumstances the Fund will invest at least 65% of its assets, as described above, in that type or style of investment. Unless otherwise stated, each Fund's investment objective is non-fundamental and may be changed without shareholder approval.

Investments in Technology Sector

Certain Funds intend to invest in competitive sectors of the economy, such as the technology sector. When investing in such sectors, the Funds may invest in companies that are exposed to the risk of increased competition and rapidly changing technology, which can result in the obsolescence of a product or technology.

Lending of Portfolio Securities

All of the Funds may lend their portfolio securities. Portfolio securities may be loaned to brokers, dealers and financial institutions to realize additional income under guidelines adopted by the Board. A risk of lending portfolio securities, as with other extensions of credit, is the possible loss of rights in the collateral should the borrower fail financially. In determining whether to lend securities, the Manager, the Subadvisor, or its agent, will consider all relevant facts and circumstances, including the creditworthiness of the borrower.

Portfolio Turnover

Portfolio turnover measures the amount of trading a Fund does during the year. Due to their trading strategies, certain Funds may experience a portfolio turnover rate of over 100%. The portfolio turnover rate for each Fund is found in the Financial Highlights. The use of certain investment strategies may generate increased portfolio turnover. A Fund with a high turnover rate (at or over 100%) often will have higher transaction costs (which are paid by the Fund) and may generate short-term capital gains (on which you'll pay taxes, even if you don't sell any shares by year-end).

Real Estate Investment Trusts ("REITs")

The Funds may invest in REITs. Investment in REITs carries with it many of the risks associated with direct ownership of real estate, including declines in property values, extended vacancies, increases in property taxes, and changes in interest rates. In addition to these risks, REITs are dependent upon management skills, may not be diversified, may experience substantial cost in the event of borrower or lessee defaults, and are subject to heavy cash flow dependency.

Risk Management Techniques

Various techniques can be used to increase or decrease a Fund's exposure to changing security prices, interest rates, currency exchange rates, commodity prices or other factors that affect security values. These techniques may involve derivative transactions such as buying and selling futures contracts and options on futures contracts, entering into foreign currency transactions (such as foreign currency forward contracts and options on foreign currencies) and purchasing put or call options on securities and securities indices.

These practices can be used in an attempt to adjust the risk and return characteristics of a Fund's portfolio of investments. For example, to gain exposure to a particular market, a Fund may be able to purchase a futures contract with respect to that market. The use of such techniques in an attempt to reduce risk is known as "hedging." If the Manager or Subadvisor judges market conditions incorrectly or employs a strategy that does not correlate well with the Fund's investments, these techniques could result in a loss, regardless of whether the intent was to reduce risk or increase return. These techniques may increase the volatility of a Fund and may involve a small investment of cash relative to the magnitude of the risk assumed. In addition, these techniques could result in a loss if the counterparty to the transaction does not perform as promised.

Swap Agreements

Certain Funds may enter into interest rate, credit default, index, equity, and currency exchange rate swap agreements to attempt to obtain a desired return at a lower cost than a direct investment in an instrument yielding that desired return. For additional information on swaps, see "Derivative Securities" above.

Whether a Fund's use of swap agreements will be successful will depend on whether the Manager or Subadvisor correctly predicts movements in interest rates, indices and currency exchange rates. Because they are two-party contracts and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid. There is a risk that the other party could go bankrupt and the Fund would lose the value of the security it should have received in the swap. See the "Tax Information" section in the SAI for information regarding the tax considerations relating to swap agreements.

Temporary Defensive Investments

In times of unusual or adverse market, economic or political conditions, for temporary defensive purposes or for liquidity purposes, each Fund may invest outside the scope of its principal investment strategies. Under such conditions, a Fund may not invest in accordance with its investment objective or principal investment strategies and, as a result, there is no assurance that the Fund will achieve its investment objective. Under such conditions, a Fund may invest without limit in cash or money market and other investments.

When-Issued Securities and Forward Commitments

Debt securities are often issued on a when-issued or forward commitment basis. The price (or yield) of such securities is fixed at the time a commitment to purchase is made, but delivery and payment for the securities take place at a later date. During the period between purchase and settlement, no payment is made by the Fund and no interest accrues to the Fund. There is a risk that the security could be worth less when it is issued than the price the Fund agreed to pay when it made the commitment. Similarly, a Fund may commit to purchase a security at a future date at a price determined at the time of the commitment. The same procedure and risks exist for forward commitments as for when-issued securities.

The following pages are intended to help you understand the costs associated with buying, holding and selling your Fund investments. Please note that shares of the Funds may not be currently available for purchase by foreign investors.

Before You Invest:
Deciding Which Class of Shares to Buy

This Prospectus offers Investor Class, and Classes A, C and I shares of the Funds. Each share class of a Fund represents an interest in the same portfolio of securities, but each class has its own sales charge and expense structure, providing you with different choices for meeting the needs of your situation. Depending upon how you wish to purchase shares of a Fund and the Fund in which you wish to invest, the share classes available to you may vary.

The decision as to which class of shares is best suited to your needs depends on a number of factors that you should discuss with your financial advisor. Important factors to consider include:

• how much you plan to invest;

• how long you plan to hold your shares;

• total expenses associated with each class of shares; and

• whether you qualify for any reduction or waiver of sales charge.

As with any business, running a mutual fund involves costs. There are regular Fund operating costs, such as investment advisory fees, marketing and distribution expenses, and custodial, transfer agency, legal and accounting fees. These Fund-wide operating costs are typically paid from the assets of a Fund, and thus, all investors in the Fund indirectly share the costs. These expenses for each Fund are presented earlier in this Prospectus in the tables titled, "Fees and Expenses of the Fund," under the heading, "Annual Fund Operating Expenses." As the fee tables show, certain costs are borne equally by each share class. In cases where services or expenses are class-specific, the costs may be allocated differently among the share classes. Most significant among the class-specific costs are:

• Distribution and/or Service (12b-1) Fee —named after the Securities and Exchange Commission ("SEC") rule that permits their payment, "12b-1 fees" are paid by a class of shares to the Funds' distributor, NYLIFE Distributors LLC ("Distributor"), for distribution and/or shareholder services such as marketing and selling Fund shares, compensating brokers and others who sell Fund shares, advertising, printing and mailing of prospectuses, responding to shareholder inquiries, etc.

An important point to keep in mind about 12b-1 fees and shareholder service fees is that they reduce the value of your shares, and therefore, will proportionately reduce the returns you receive on your investment and any dividends that are paid. See "Information on Fees" in this section for more information about these fees.

In addition to regular Fund operating costs, there are costs associated with an individual investor's transactions and account, such as the compensation paid to your financial advisor for helping you with your investment decisions or redemption fees imposed to discourage short-term trading. The Funds typically cover such costs by imposing sales charges and other fees directly on the investor either at the time of purchase or upon redemption. These charges and fees for each Fund are presented earlier in this Prospectus in the tables entitled, "Fees and Expenses of the Fund," under the heading, "Shareholder Fees." Such charges and fees include:

• Initial Sales Charge —also known as a "front-end sales load," refers to a charge that is deducted from your initial investment in Investor Class and Class A shares and is used to compensate the Distributor and/or your financial advisor for their efforts and assistance to you in connection with the purchase. The key point to keep in mind about a front-end sales load is that it reduces the amount available to purchase Fund shares.

• Contingent Deferred Sales Charge —also known as a "CDSC" or "back-end sales load," refers to a sales load that is deducted from the proceeds when you redeem Fund shares (that is, sell shares back to the Fund). The amount of the CDSC that you pay will depend on how long you hold your shares and decreases to zero if you hold your shares long enough. Although you pay no sales charge at the time of purchase, the Distributor typically pays your financial advisor a commission up-front. In part to compensate the Distributor for this expense over time, you will pay a higher ongoing 12b-1 fee. Over time, these fees may cost you more than paying an initial sales charge.

Distribution and/or service (12b-1) fees, initial sales charges and contingent deferred sales charges are each discussed in more detail in this Shareholder Guide. The following table gives you a summary of the differences among share classes with respect to such fees and other important factors:

The following discussion is not intended to be investment advice or a recommendation because each investor's financial situation and considerations are different. Additionally, certain Funds have sales charge and expense structures that may alter your analysis as to which share class is most appropriate for your needs. This analysis can best be made by discussing your situation and the factors mentioned above with your financial advisor. Generally, however, Investor Class shares or Class A shares are more economical if you intend to invest larger amounts and hold your shares long-term (more than 6 years, for most Funds). Class C shares may be more economical if you intend to hold your shares for a shorter term (6 years or less, for most Funds). Class I shares are the most economical, regardless of amount invested or intended holding period, but are offered only to certain institutional investors or through certain financial intermediary accounts.

Investor Class Share Considerations

• Your Investor Class shares may convert automatically to Class A shares. Investor Class share balances are examined Fund-by-Fund on a quarterly basis. If at that time the value of your Investor Class shares in any one Fund equals or exceeds $25,000, whether by shareholder action or change in market value, or if you have otherwise become eligible to invest in Class A shares, your Investor Class shares of that Fund will be automatically converted into Class A shares. Please note that, in most cases, you may not aggregate your holdings of Investor Class shares in multiple Funds/accounts or rely on a Right of Accumulation or Letter of Intent (each discussed below) in order to qualify for this conversion feature. To discuss ways to qualify for this automatic conversion, please contact your investment advisor/plan administrator or the Funds by calling toll-free 800-MAINSTAY (624-6782) .

• Please also note that if your account balance falls below $25,000 ($15,000 for investors that meet certain asset thresholds), whether by shareholder action or change in market value, after conversion to Class A shares or you otherwise no longer qualify to hold Class A shares, your account may be converted automatically to Investor Class shares. Please see "Class A Share Considerations" for more details.

• The conversion is based on the relevant NAVs of the two classes at the time of the conversion and no sales load or other charge is imposed. The Funds expect all share conversions to be made on a tax-free basis. The Funds reserve the right to modify or eliminate the share class conversion feature.

• When you invest in Investor Class shares, you pay the public offering price, which is the share price, or NAV, plus the initial sales charge that may apply to your purchase. The amount of the initial sales charge is based on the size of your investment (see "Information on Sales Charges"). We also describe below how you may reduce or eliminate the initial sales charge (see "Sales Charge Reductions and Waivers on Investor Class Shares and Class A Shares").

• Since some of your investment goes to pay an up-front sales charge when you purchase Investor Class shares, you will purchase fewer shares than you would with the same investment in other share classes. Nevertheless, you're usually better off purchasing Investor Class shares rather than Class C shares and paying an up-front sales charge if you:

  • plan to own the shares for an extended period of time, since the higher ongoing service and/or distribution (12b-1) fees on Class C shares may eventually exceed the cost of the up-front sales charge; or

  • qualify for a reduced or waived sales charge.

Class A Share Considerations

• Generally, Class A shares have a minimum initial investment amount of [$25,000] per Fund. Class A share balances are examined Fund-by-Fund on a semi-annual basis. If at that time the value of your Class A shares in any one Fund is less than [$25,000] ($10,000 in the case of IRA or 403(b)(7) accounts that are making required minimum distributions via MainStay's systematic withdrawal plan or systematic exchange program, and [$15,000] in the case of investors with $100,000 or more invested in any of the MainStay Funds combined, regardless of share class), whether by shareholder action or change in market value, or if you are otherwise no longer eligible to hold Class A shares, your Class A shares of that Fund will be converted automatically into Investor Class shares. Please note that you may not aggregate holdings of Class A shares in multiple Funds/accounts or rely on a Right of Accumulation or Letter of Intent (each discussed below) in order to avoid this conversion feature.

Please note that if you qualify for the [$15,000] minimum initial investment, you must maintain aggregate investments of $100,000 or more in the MainStay Funds, regardless of share class, and an account balance at or above [$15,000] per Fund to avoid having your account automatically convert into Investor Class shares.

• The conversion is based on the relevant NAVs of the two classes at the time of the conversion and no sales load or other charge is imposed. The Funds expect all share conversions to be made on a tax-free basis. The Funds reserve the right to modify or eliminate the share class conversion feature. When a conversion occurs, reinvested dividends and capital gains convert with the shares that are converting.

• When you invest in Class A shares, you pay the public offering price, which is the share price, or NAV, plus the initial sales charge that may apply to your purchase. The amount of the initial sales charge is based on the size of your investment (see "Information on Sales Charges"). We also describe below how you may reduce or eliminate the initial sales charge (see "Sales Charge Reductions and Waivers on Investor Class Shares and Class A Shares").

• Since some of your investment goes to pay an up-front sales charge when you purchase Class A shares, you will purchase fewer shares than you would with the same investment in other share classes. Nevertheless, you're usually better off purchasing Class A shares rather than Class C shares and paying an up-front sales charge if you:

  • plan to own the shares for an extended period of time, since the higher ongoing service and/or distribution (12b-1) fees on Class C shares may eventually exceed the cost of the up-front sales charge; or

  • qualify for a reduced or waived sales charge.

Class C Share Considerations

• You pay no initial sales charge on an investment in Class C shares. However, you will pay higher ongoing service and/or distribution fees over the life of your investment.

• In most circumstances, you will pay a 1% CDSC if you redeem shares held for one year or less.

• When you sell Class C shares, to minimize your sales charges, the Fund first redeems the shares that have no sales charges (shares representing the amount of any appreciation on the original value of your shares, fully aged shares and any shares received through the reinvestment of dividends and capital gains) and then the shares you have held longest.

• Class C shares do not convert to Investor Class or Class A shares. As a result, long-term Class C shareholders pay higher ongoing service and/or distribution fees over the life of their investment.

• The Funds will generally not accept a purchase order for Class C shares in the amount of $1,000,000 or more.

Class I Share Considerations

• You pay no initial sales charge or CDSC on an investment in Class I shares.

• You do not pay any ongoing service or distribution fees.

• You may buy Class I shares if you are an:

  • Institutional Investor

    • certain employer-sponsored, association or other group retirement plans or employee benefit trusts with a service arrangement through New York Life Retirement Plan Services or NYLIFE Distributors LLC;

    • certain financial institutions, endowments, foundations or corporations with a service arrangement through NYLIFE Distributors LLC or its affiliates; or

    • purchases through a program sponsored by a financial intermediary firm (such as a broker-dealer, investment adviser or financial institution) with a contractual arrangement with NYLIFE Distributors LLC.

  • Individual Investor —who is initially investing at least $5 million in any single MainStay Fund.

  • Existing Class I Shareholder

Investment Minimums and Eligibility Requirements

The following minimums apply if you are investing in the Funds. A minimum initial investment amount may be waived for purchases by the Funds' Board Members and directors and employees of New York Life and its affiliates and subsidiaries. The Funds may also waive investment minimums for certain qualified purchases and accept additional investments of smaller amounts at their discretion. Please see the SAI for additional information.

Investor Class Shares

The following minimums apply if you are investing in Investor Class shares of the Funds:

• [$1,000] minimum for initial and $50 minimum for subsequent purchases of any single MainStay Fund, or

• if through AutoInvest, a monthly systematic investment plan: [$500] minimum for initial and $50 minimum for subsequent monthly purchases OR no initial minimum and $100 minimum for subsequent monthly purchases.

[Additionally, SIMPLE IRA Plan accounts and certain other retirement plan accounts may not be eligible to invest in the Funds.] Please contact your investment advisor/plan administrator or the Funds by calling toll-free 800-MAINSTAY (624-6782) for more information.

Please note that your Investor Class shares may be converted into Class A shares automatically. See "Investor Class Share Considerations" for more details.

Class A Shares

The following minimums apply if you are investing in Class A shares of the Funds:

• [$25,000] minimum initial investment with no minimum subsequent purchase amount requirement for any single MainStay Fund; or

• [$15,000] minimum initial investment with no minimum subsequent purchase amount for investors that, in the aggregate, have assets of $100,000 or more invested in any share class of any of the MainStay Funds. To qualify for this investment minimum, all aggregated accounts must be tax reportable under the same tax identification number. You may not aggregate your holdings with the holdings of any other person or entity to qualify for this investment minimum. Please note that accounts held through broker/dealers or other types of institutions may not be aggregated to qualify for this investment minimum. We will only aggregate those accounts held directly with the Funds. Please contact your investment advisor or the Funds by calling 800-MAINSTAY (624-6782) for more information.

Additionally, please note that if you qualify for this exception, you must also maintain the aggregate assets of $100,000 or more invested in any share classes of any of the MainStay Funds and an account balance at or above $15,000 per Fund to avoid having your account automatically convert into Investor Class shares.

Broker/dealers (and their affiliates) or certain service providers with customer accounts that trade primarily on an omnibus level or through the National Securities Clearing Corporation's Fund/SERV network (Levels 1-3 only); certain retirement plan accounts, including investment-only plan accounts; the Funds' Board Members; directors and employees of New York Life and its affiliates; and subsidiaries and employees of the Funds' Subadvisors are not subject to the minimum investment requirement for Class A shares. Please contact your investment advisor/plan administrator or the Funds by calling toll-free 800-MAINSTAY (624-6782) for more information.

Please note that your Class A shares may be converted into Investor Class shares automatically. Please see "Class A Share Considerations" for more details.

Class C Shares

The following minimums apply if you are investing in Class C shares of the Funds:

• $1,000 minimum for initial and $50 minimum for subsequent purchases of any single MainStay Fund, or

• if through AutoInvest, a monthly systematic investment plan: $500 minimum for initial and $50 minimum for subsequent monthly purchases OR no initial minimum and $100 minimum for subsequent monthly purchases.

Class I Shares

The following minimums apply if you are investing in Class I shares of the Funds:

• Individual Investors—$5 million minimum for initial purchases of any single MainStay Fund and no minimum subsequent purchase amount, and

• Institutional Investors—no minimum initial or subsequent purchase amounts.

Information on Sales Charges

Investor Class Shares and Class A Shares

The initial sales charge you pay when you buy Investor Class shares or Class A shares differs depending upon the Fund you choose and the amount you invest, as indicated in the following tables. The sales charge may be reduced or eliminated for larger purchases, as described below, or as described under "Sales Charge Reductions and Waivers on Investor Class Shares and Class A Shares." Any applicable sales charge will be deducted directly from your investment. All or a portion of the sales charge may be retained by the Distributor or allocated to your dealer/financial advisor as a concession.

Class C Shares

Class C shares are sold without an initial sales charge. However, if Class C shares are redeemed within one year of purchase, a CDSC of 1.00% will be deducted from the redemption proceeds, except under circumstances described in the SAI. Additionally, Class C shares have higher ongoing service and/or distribution fees, and, over time these fees may cost you more than paying an initial sales charge. The Class C share CDSC and the higher ongoing service and/or distribution fees are paid to compensate the Distributor for its expenses in connection with the sale of Class C shares.

Computing Contingent Deferred Sales Charge on Class C

A CDSC may be imposed on redemptions of Class C shares of a Fund, at the rate previously described, at the time of any redemption by a shareholder that reduces the current value of the shareholder's Class C account in the Fund to an amount that is lower than the amount of all payments by the shareholder for the purchase of Class C shares in the Fund for the preceding year.

However, no such charge will be imposed to the extent that the net asset value of the Class C shares redeemed does not exceed:

• the current aggregate net asset value of Class C shares of the Fund purchased more than one year prior to the redemption for Class C shares; plus

• the current aggregate net asset value of Class C shares of the Fund purchased through reinvestment of dividends or distributions; plus

• increases in the net asset value of the investor's Class C shares of the Fund above the total amount of payments for the purchase of Class C shares of the Fund made during the preceding one year.

There are exceptions, which are described in the SAI.

Sales Charge Reductions and Waivers on Investor Class Shares and Class A Shares

Reducing the Initial Sales Charge on Investor Class Shares and Class A Shares

You may be eligible to buy Investor Class and Class A shares of the Funds at one of the reduced sales charge rates shown in the tables above through a Right of Accumulation or a Letter of Intent, as described below. You may also be eligible for a waiver of the initial sales charge as set forth below. Each Fund reserves the right to modify or eliminate these programs at any time. However, please note the Right of Accumulation or Letter of Intent may only be used to reduce sales charges and may not be used to satisfy investment minimums or to avoid the automatic conversion feature of Investor Class or Class A shares.

• Right of Accumulation

A Right of Accumulation allows you to reduce the initial sales charge as shown in the tables above by combining the amount of your current purchase with the current market value of investments made by you, your spouse, and your children under age 21 in Investor Class, Class A, or Class C shares of most MainStay Funds. You may not include investments of previously non-commissioned shares in the MainStay Money Market Fund (which is offered in a separate prospectus), investments in Class I shares, or your interests in any MainStay Fund held through a 401(k) plan or other employee benefit plan. For example, if you currently own $45,000 worth of Class C shares of a MainStay Fund, your spouse owns $50,000 worth of Class C shares of another MainStay Fund, and you wish to invest $15,000 in a Fund, using your Right of Accumulation you can invest that $15,000 in Investor Class or Class A shares (if eligible) and pay the reduced sales charge rate normally applicable to a $110,000 investment. For more information, see "Purchase, Redemption, Exchanges and Repurchase—Reduced Sales Charges" in the SAI.

• Letter of Intent

Where the Right of Accumulation allows you to use prior investments to reach a reduced initial sales charge, a Letter of Intent allows you to qualify for a discount by combining your current purchase amount with purchases you, your spouse or children under age 21 intend to make in the near future. A Letter of Intent is a written statement to the Distributor of your intention to purchase Investor Class or Class A shares of one or more MainStay Funds (excluding investments of previously non-commissioned shares in the MainStay Money Market Fund) over a 24-month period. The total amount of your intended purchases will determine the reduced sales charge rate that will apply to Investor Class or Class A shares (if eligible) of the Funds purchased during that period. You can include purchases in Investor Class or Class A shares made up to 90 days before the date of the Letter of Intent. You can also apply a Right of Accumulation to these purchases.

Your Letter of Intent goal must be at least $100,000. Submitting a Letter of Intent does not obligate you to purchase the specified amount of shares. If you do not meet your intended purchase goal, however, the initial sales charge that you paid on your purchases will be recalculated to reflect the actual value of shares you purchased. A certain portion of your shares will be held in escrow by the Funds' Transfer Agent for this purpose. For more information, see "Purchase, Redemption, Exchanges and Repurchase—Letter of Intent" in the SAI.

• Your Responsibility

To receive the reduced sales charge, you must inform the Fund's Distributor of your eligibility and holdings at the time of your purchase if you are buying shares directly from the Funds. If you are buying shares through a financial intermediary firm, you must tell your financial advisor of your eligibility for a Right of Accumulation or a Letter of Intent at the time of your purchase.

To combine shares of eligible MainStay Funds held in accounts at other intermediaries under your Right of Accumulation or a Letter of Intent, you may be required to provide the Distributor or your financial advisor a copy of each account statement showing your current holdings of each eligible MainStay Fund, including statements for accounts held by you, your spouse or your minor children, as described above. The Distributor or intermediary through which you are buying shares will combine the value of all your eligible MainStay Fund holdings based on the current net asset value per share to determine what Investor Class or Class A sales charge rate you may qualify for on your current purchase. If you do not inform the Distributor or your financial advisor of all of the holdings or planned purchases that make you eligible for a sales charge reduction or do not provide requested documentation, you may not receive a discount to which you are otherwise entitled.

More information on Investor Class and Class A share sales charge discounts is available in the SAI (see "Purchase, Redemption, Exchanges and Repurchase") or on the internet at mainstayinvestments.com (under the "Shareholder Services" tab).

"Spouse" with respect to a Right of Accumulation and Letter of Intent is defined as the person to whom you are legally married. We also consider your spouse to include the following: i) an individual of the same gender with whom you have been joined in a civil union or legal contract similar to marriage; ii) a domestic partner, who is an individual (including one of the same gender) to whom you are not related by blood and with whom you have shared a primary residence for at least six months in a relationship as a couple where you, your domestic partner or both of you provide for the personal or financial welfare of the other without a fee; or iii) an individual with whom you have a common law marriage, which is a marriage in a state where such marriages are recognized between a man and a woman arising from the fact that the two live together and hold themselves out as being married.

Group Benefit Plan Purchases

You will not pay an initial sales charge if you purchase Investor Class shares or Class A shares through a group retirement or other benefit plan (other than IRA plans) that meets certain criteria, including:

• 50 or more participants; or

• an aggregate investment in shares of any class of the MainStay Funds of $1,000,000 or more.

However, Investor Class shares or Class A shares purchased through a group retirement or other benefit plan (other than IRA plans) will be subject to a contingent deferred sales charge upon redemption.

Purchases Through Financial Services Firms

You may be eligible for elimination of the initial sales charge if you purchase shares through a financial services firm (such as a broker-dealer, investment advisor or financial institution) that has a contractual arrangement with the Distributor. The Funds have authorized these firms (and other intermediaries that the firms may designate) to accept orders. When an authorized firm or its designee has received your order, it is considered received by the Fund and will be priced at the next computed NAV. Financial services firms may charge transaction fees or other fees and may modify other features such as minimum investment amounts and exchange privileges.

Please read their program materials for any special provisions or additional service features that may apply to investing in the Funds through these firms.

529 Plans

When shares of the Funds are sold to a qualified tuition program operating under Section 529 of the Internal Revenue Code, such a program may purchase Investor Class shares or Class A shares without an initial sales load.

Other Waivers

There are other categories of purchasers who do not pay initial sales charges on Class A shares, such as personnel of the Funds and of New York Life Insurance Company ("New York Life") and its affiliates or shareholders who owned shares of the Service Class of any MainStay Fund as of December 31, 2003. These categories are described in the SAI.

Contingent Deferred Sales Charge on Certain Investor Class and Class A Share Redemptions

If your initial sales charge is eliminated, we may impose a CDSC of 1.00% if you redeem or exchange your shares within one year. The Funds' Distributor may pay a commission to dealers on these purchases from its own resources.

For more information about these considerations, call your financial advisor or the Funds' transfer agent, NYLIM Service Company LLC ("MainStay Investments"), an affiliate of New York Life Investments, toll-free at 800-MAINSTAY (624-6782), and read the information under "Purchase, Redemption, Exchanges and Repurchase" in the SAI.

Information on Fees

Rule 12b-1 Plans

Each Fund has adopted a distribution plan under Rule 12b-1 of the 1940 Act for certain classes of shares pursuant to which service and/or distribution fees are paid to the Distributor. The Investor Class and Class A 12b-1 plans typically provide for payment for distribution or service activities of up to 0.25% of the average annual net assets of Investor Class and Class A shares of the Fund, respectively. The Class C 12b-1 plan provides for payment of both distribution and/or service activities of up to 1.00% of the average annual net assets of Class C shares of the Fund. The distribution fee is intended to pay the Distributor for distribution services, which include any activity or expense primarily intended to result in the sale of Fund shares. The service fee is paid to the Distributor for providing shareholders with personal services and maintaining shareholder accounts. The portion of the 12b-1 fee dedicated to service activities is in addition to the 0.10% of annual net assets paid from the Shareholder Services Plan, with regard to certain classes. The Distributor may pay all or a portion of the 12b-1 fee to your investment professional. Because Rule 12b-1 fees are ongoing, over time they will increase the cost of an investment in the Fund and may cost more than other types of sales charges.

Small Account Fee

Several of the Funds have a relatively large number of shareholders with small account balances. Small accounts adversely impact the cost of providing transfer agency services. In an effort to reduce total transfer agency expenses, the Funds have implemented a small account fee. Each shareholder with an account balance of less than $1,000 will be charged an annual per account fee of $20 (assessed semi-annually, as discussed below). The fee may be deducted directly from your fund balance. This small account fee will not apply to certain types of accounts including:

• Class A share and Class I share accounts, retirement plan services bundled accounts and investment-only retirement accounts;

• accounts with active AutoInvest plans or systematic investment programs where the Funds deduct directly from the client's checking or savings account;

• New York Life Investments SIMPLE IRA Plan Accounts and SEP IRA Accounts that have been funded/established for less than 1 year;

• 403(b)(7) accounts; and

• accounts serviced by unaffiliated broker/dealers or third party administrators (other than New York Life Investments SIMPLE IRA Plan Accounts).

This small account fee will be deducted in $10 increments on or about March 1st and September 1st of each year. The Funds may, from time to time, consider and implement additional measures to increase average shareholder account size and/or otherwise reduce the cost of transfer agency services. Please contact the Funds by calling toll-free 800-MAINSTAY (624-6782) for more information.

Redemption Fee

Each Fund, except for MainStay Epoch U.S. Equity Fund, imposes a redemption fee of 2.00% of the total redemption amount (calculated at market value) on redemptions (including exchanges) of any class of shares made within 60 days of purchase. The redemption fees are received directly by the Fund and are implemented as a 2.00% reduction in the proceeds that would otherwise be received by a redeeming shareholder. The redemption fee is designed to offset transaction and administrative costs associated with, and to discourage certain types of, short-term trading. For purposes of determining whether the redemption fee applies, the shares that were held the longest will be redeemed first. The redemption fee will not apply to shares acquired through the reinvestment of dividends or distributions paid by the Fund. The redemption fee may not apply to redemptions by certain benefit plan accounts such as:

• 401(k) plans;

• Section 529 qualified tuition plans;

• accounts held in omnibus accounts on the books of certain financial intermediary firms;

• wrap program accounts;

• qualified default investment alternative accounts; or

• redemptions of shares held at the time of death or the initial determination of a permanent disability of a shareholder.

The redemption fee does not apply on redemptions effected through a MainStay Investments Systematic Withdrawal/Exchange Plan. Please contact us at 800-MAINSTAY (624-6782) if you have questions as to whether the redemption fee applies to some or all of your shares.

Compensation to Dealers

Financial intermediary firms and their associated financial advisors are paid in different ways for the services they provide to the Funds and shareholders. Such compensation may vary depending upon the Fund sold, the amount invested, the share class purchased, the amount of time that shares are held and/or the services provided.

• The Distributor pays sales concessions to dealers, as described in the tables under "Information on Sales Charges" above, on the purchase price of Investor Class or Class A shares sold subject to a sales charge. The Distributor retains the difference between the sales charge that you pay and the portion that is paid to dealers as a sales concession.

• The Distributor or an affiliate, from its own resources, pays a sales concession of up to 1.00% of the purchase price of Investor Class or Class A shares, sold at net asset value, to dealers at the time of sale.

• The Distributor pays a sales concession of 1.00% on purchases of Class C shares to dealers from its own resources at the time of sale.

• The Distributor pays, pursuant to a 12b-1 plan, distribution-related and other service fees to qualified dealers for providing certain shareholder services.

• In addition to the payments described above, the Distributor or an affiliate, from its own resources, may pay other significant amounts to certain financial intermediary firms, including an affiliated broker-dealer, in connection with the sale of any class of Fund shares and/or shareholder or account servicing arrangements. These sales and/or servicing fee arrangements vary and may amount to payments of up to 0.25% on new sales and/or up to 0.25% annually on assets held.

• The Distributor may pay a finder's fee or other compensation to third parties in connection with the sale of Fund shares and/or shareholder or account servicing arrangements.

• The Distributor or an affiliate may sponsor training or informational meetings or provide other non-monetary benefits for financial intermediary firms and their associated financial advisors.

• The Distributor or an affiliate may make payments to financial intermediaries that provide sub-transfer agency and other administrative services in addition to supporting distribution of the Funds. A portion of these fees may be paid from the Distributor's or its affiliate's own resources.

• Wholesaler representatives of the Distributor visit brokerage firms on a regular basis to educate financial advisors about the Funds and to encourage the sale of the Fund shares to their clients. The costs and expenses associated with these efforts may include travel, lodging, sponsorship at educational seminars and conferences, entertainment and meals to the extent permitted by law. The Distributor, from its own resources or from those of an affiliate, provides compensation to its wholesaler representatives for their sales efforts in promoting sales of the Funds, which may vary based on the type of Fund being promoted.

Although the Funds may use financial firms that sell Fund shares to make transactions for a Fund's portfolio, the Funds, the Manager and any Subadvisor do not consider the sale of Fund shares as a factor when choosing financial firms to effect those transactions.

Payments made from the Distributor's or an affiliate's own resources do not increase the price or decrease the amount or value of the shares you purchase. However, if investment advisers, distributors or affiliates of mutual funds make such payments in differing amounts, financial intermediary firms and their financial advisors may have financial incentives for recommending a particular mutual fund or a particular share class of that fund over other mutual funds. For example, payments made by the Distributor or an affiliate, as described above, may be used by the financial intermediary firm to reduce or eliminate transaction charges associated with purchases of Fund shares.

For more information regarding any of the types of compensation described above, see the SAI or consult with your financial intermediary firm or financial advisor. You should review carefully any disclosure by your financial intermediary firm as to compensation received by that firm and/or your financial advisor.

Buying, Selling, Converting and Exchanging Fund Shares

How to Open Your Account with MainStay Investments

Investor Class, Class A or C Shares

Return your completed MainStay Funds application in good order with a check payable to the MainStay Funds for the amount of your investment to your financial advisor or directly to MainStay Funds, P.O. Box 8401, Boston, Massachusetts 02266-8401. If you place your order by phone, MainStay Investments must receive your completed application and check in good order within three business days. Please note that if you select Class A shares on your application and you are not eligible to invest in Class A shares, we will treat your application as being in good order but will invest you in Investor Class shares of the same Fund. Similarly, if you select Investor Class shares and you are eligible to invest in Class A shares we will treat your application as being in good order but will invest you in Class A shares of the same Fund.

Good order means all the necessary information, signatures and documentation have been fully completed.

Class I Shares

If you are participating in a company savings plan, such as a 401(k) plan, profit sharing plan, defined benefit plan or other employee-directed plan, your company will provide you with the information you need to open an account and buy or sell Class I shares of the Funds.

If you are investing through a financial intermediary firm, the firm will assist you with opening an account. Your financial advisor may place your order by phone. MainStay Investments must receive your completed application and check in good order within three business days.

All Classes

You buy shares at net asset value ("NAV") (plus, for Investor Class and Class A shares, any applicable sales charge). NAV is generally calculated as of the close of regular trading (usually 4:00 pm Eastern time) on the New York Stock Exchange (the "Exchange") every day the Exchange is open. NAV is not calculated on days on which the Exchange is closed. When you buy shares, you must pay the NAV next calculated after MainStay Investments receives your order in good order. Alternatively, MainStay Funds has arrangements with certain financial intermediary firms whereby purchase orders through these entities are considered received in good order when received by the financial intermediary firm together with the purchase price of the shares ordered. The order will then be priced at a Fund's NAV next computed after receipt in good order of the order by these entities. Such financial intermediary firms are responsible for timely transmitting the purchase order to the Funds.

When you open your account, you may also want to choose certain buying and selling options, including transactions by wire. In most cases, these choices can be made later in writing, but it may be quicker and more convenient to decide on them when you open your account.

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 a new account and to determine whether such person's name appears on government lists of known or suspected terrorists and terrorist organizations. As a result, the Funds, or your financial advisor on their behalf, must obtain the following information for each person who opens a new account:

• Name;

• Date of birth (for individuals);

• Residential or business street address (although post office boxes are still permitted for mailing); and

• Social security number, taxpayer identification number, or other identifying number.

You may also be asked for a copy of your driver's license, passport or other identifying document in order to verify your identity. In addition, it may be necessary to verify your identity by cross-referencing your identification information with a consumer report or other electronic database. Additional information may be required to open accounts for corporations and other entities.

Federal law prohibits the Funds and other financial institutions from opening a new account unless they receive the minimum identifying information listed above.

After an account is opened, the Funds may restrict your ability to purchase additional shares until your identity is verified. The Funds also may close your account or take other appropriate action if they are unable to verify your identity within a reasonable time. If your account is closed for this reason, your shares will be redeemed at the NAV next calculated after the account is closed.

Conversions Between Share Classes

In addition to any automatic conversion features described above in this Shareholder Guide with respect to Investor Class and Class A shares, you generally may also elect to convert your shares on a voluntary basis into another share class of the same Fund for which you are eligible. However, the following limitations apply:

• Investor Class and Class A shares that remain subject to a CDSC are ineligible for a voluntary conversion; and

• All Class C shares are ineligible for a voluntary conversion.

These limitations do not impact any automatic conversion features described elsewhere in this Shareholder Guide with respect to Investor Class and Class A shares.

To request a voluntary conversion between share classes of the same Fund, you may contact the Fund, either directly or through your financial intermediary firm. You may be required to provide sufficient information to establish eligibility to convert to the new share class. All permissible conversions will be made on the basis of the relevant net asset values of the two classes without the imposition of any sales load, fee or other charge. If you fail to remain eligible for the new share class, you may automatically be converted back to your original share class, or into another share class, if appropriate. Although the Funds expect that a conversion between share classes of the same Fund should not result in the recognition of a gain or loss for tax purposes, you should consult with your own tax adviser with respect to the tax treatment of your investment in a Fund. The Funds may change, suspend or terminate this conversion feature at any time.

General Policies

The following are MainStay Investments' general policies regarding the purchase and sale of Fund shares. Certain retirement plans and/or financial intermediaries may adopt different policies. Consult your plan or account documents for the policies applicable to you.

Buying Shares

• All investments must be in U.S. dollars with funds drawn on a U.S. bank. We will not accept any payment in the following forms: travelers checks, personal money orders, credit card convenience checks, cash or starter checks.

• MainStay Investments does not accept third-party checks, and it reserves the right to limit the number of checks processed at one time.

• If your investment check or ACH purchase does not clear, your order will be canceled and your account will be responsible for any losses or fees a Fund incurs as a result. Your account will be charged a $20 fee for each returned check or ACH purchase. In addition, a Fund may also redeem shares to cover any losses it incurs as a result. If an AutoInvest payment is returned unpaid for two consecutive periods, the privilege will be suspended until you notify us to reinstate it.

• A Fund may, in its discretion, reject, restrict or cancel, in whole or in part, without prior notice, any order for the purchase of shares.

• To limit the Funds' expenses, we no longer issue share certificates.

Selling Shares

• If you have share certificates, you must return them with a written redemption request.

• Your shares will be sold at the next NAV calculated after MainStay Investments receives your request in good order. MainStay Investments will make the payment within seven days after receiving your request in good order.

• If you buy shares by check or by ACH purchase and quickly decide to sell them, the Fund may withhold payment for 10 days from the date the check or ACH purchase order is received.

• When you sell Class C shares, or Investor Class or Class A shares when applicable, the Fund will recover any applicable sales charges either by selling additional shares, if available, or by reducing your proceeds by the amount of those charges.

• There will be no redemption during any period in which the right of redemption is suspended or date of payment is postponed because the New York Stock Exchange is closed or trading on the New York Stock Exchange is restricted or the SEC deems an emergency to exist.

• Unless you decline telephone privileges on your application, you may be responsible for any fraudulent telephone order as long as MainStay Investments takes reasonable measures to verify the order.

• Reinvestment won't relieve you of any tax consequences on gains realized from a sale. The deductions for losses, however, may be denied.

• MainStay Investments requires a written order to sell shares if an account has submitted a change of address during the previous 30 days, unless the proceeds of the sell order are directed to your bank account on file with the Funds.

• MainStay Investments requires a written order to sell shares and a Medallion Signature Guarantee if:

  • MainStay Investments does not have on file required bank information to wire funds;

  • the proceeds from the sale will exceed $100,000;

  • the proceeds of the sale are to be sent to an address other than the address of record;

  • or the proceeds are to be payable to someone other than the account holder(s).

• In the interest of all shareholders, the Funds reserve the right to:

  • change or discontinue their exchange privileges upon notice to shareholders, or temporarily suspend this privilege without notice under extraordinary circumstances;

  • change or discontinue the systematic withdrawal plan upon notice to shareholders;

  • close accounts with balances less than $100 invested in Investor Class shares or $500 invested in Class A or Class C shares (by redeeming all shares held and sending proceeds to the address of record); and/or

  • change the minimum investment amounts.

• There is no fee for wire redemptions of Class I shares.

When you buy and sell shares directly from a Fund, you will receive confirmation statements that describe your transaction. For certain systematic transactions, you will receive quarterly confirmation statements. You should review the information in the confirmation statements carefully. If you notice an error, you should call your investment dealer or MainStay Investments immediately. If you or your investment dealer fails to notify MainStay Investments within one year of the transaction, you may be required to bear the costs of correction.

Additional Information

The policies and fees described in this Prospectus govern transactions with the MainStay Funds. If you invest through a third party—bank, broker, 401(k), financial advisor or financial supermarket—there may be transaction fees for, and you may be subject to, different investment minimums or limitations on buying or selling shares. Accordingly, the net yield to investors who purchase through financial intermediaries may be less than the net yield earned by investors who invest in a Fund directly. Consult a representative of your plan or financial institution if in doubt.

From time to time, any of the Funds may close and reopen to new investors or new share purchases at its discretion. Due to the nature of their portfolio investments, certain Funds may be more likely to close and reopen than others. If a Fund is closed, either to new investors or new share purchases, and you redeem your total investment in the Fund, your account will be closed and you will not be able to make any additional investments in the Fund. If a Fund is closed to new investors, you may not exchange shares from other MainStay Funds for shares of that Fund unless you are already a shareholder of such Fund.

Medallion Signature Guarantees

A Medallion Signature Guarantee helps protect against fraud. To protect your account, each Fund and MainStay Investments from fraud, Medallion Signature Guarantees are required to enable MainStay Investments to verify the identity of the person who has authorized redemption proceeds to be sent to a third party or a bank not previously established on the account. Medallion Signature Guarantees are also required for redemptions of $100,000 or more from an account and for share transfer requests. Medallion Signature Guarantees must be obtained from certain eligible financial institutions that are participants in the Securities Transfer Association Medallion Program (STAMP), the Stock Exchange Medallion Program (SEMP), or the New York Stock Exchange Medallion Signature Program (MSP). Eligible guarantor institutions provide Medallion Signature Guarantees that are covered by surety bonds in various amounts. It is your responsibility to ensure that the Medallion Signature Guarantee that you acquire is sufficient to cover the total value of your transaction(s). If the surety bond amount is not sufficient to cover the requested transaction(s), the Medallion Signature Guarantee will be rejected.

Signature guarantees that are not a part of these programs will not be accepted. Please note that a notary public stamp or seal is not acceptable. Shareholders may contact MainStay Investments toll-free at 800-MAINSTAY (624-6782) for further details.

Investing for Retirement

You can purchase shares of any of the MainStay Funds for retirement plans providing tax-deferred investments for individuals and institutions. You can use MainStay Funds in established plans or the Distributor may provide the required plan documents for selected plans. A plan document must be adopted for a plan to be in existence.

Custodial services are available for IRA, Roth IRA and Coverdell Education Savings Accounts ("CESA") (previously named Education IRA) as well as SEP and SIMPLE IRA plans. Plan administration is also available for select qualified retirement plans. An investor should consult with his or her tax adviser before establishing any tax-deferred retirement plan.

Not all MainStay Funds are available for all types of retirement plans or through all distribution channels. Please contact the Funds at 800-MAINSTAY (624-6782) for further details.

Purchases-In-Kind

You may purchase shares of a Fund by transferring securities to a Fund in exchange for Fund shares ("in kind purchase"). In kind purchases may be made only upon the Funds' approval and determination that the securities are acceptable investments for the Fund and are purchased consistent with the Fund's procedures relating to in kind purchases.

Redemptions-In-Kind

The Funds reserve the right to pay certain large redemptions, either totally or partially, by a distribution-in-kind of securities (instead of cash) from the applicable Fund's portfolio, consistent with the Fund's procedures relating to in-kind redemptions and in accordance with the 1940 Act and rules and interpretations of the SEC thereunder.

The Reinvestment Privilege May Help You Avoid Sales Charges

When you sell shares, you have the right—for 90 days—to reinvest any or all of the money in the same account and class of shares without paying another sales charge (so long as (1) those shares haven't been reinvested once already; (2) your account is not subject to a 60-day block as described in "Excessive Purchases and Redemptions or Exchanges"; and (3) you are not reinvesting your required minimum distribution). If you paid a sales charge when you redeemed you'll receive a pro rata credit for reinvesting in the same account and class of shares.

Reinvestment won't relieve you of any tax consequences on gains realized from a sale. The deductions for losses may, however, be denied and, in some cases, sales charges may not be taken into account in computing gains or losses if the reinvestment privilege is exercised.

Convenient, yes...but not risk-free. Telephone redemption privileges are convenient, but you give up some security. When you sign the application to buy shares, you agree that the Funds will not be liable for following phone instructions that they reasonably believe are genuine. When using the MainStay Audio Response System or the internet, you bear the risk of any loss from your errors unless the Funds or MainStay Investments fails to use established safeguards for your protection. These safeguards are among those currently in place at MainStay Funds:

• all phone calls with service representatives are tape recorded; and

• written confirmation of every transaction is sent to your address of record.

MainStay Investments and the Funds reserve the right to suspend the MainStay Audio Response System at any time or the system might become inoperable due to technical problems.

Shareholder Services

Automatic Services

Buying or selling shares automatically is easy with the services described below. You select your schedule and amount, subject to certain restrictions. You can set up most of these services on your application by accessing your shareholder account on the internet at mainstayinvestments.com, contacting your financial advisor for instructions, or by calling MainStay Investments toll-free at 800-MAINSTAY (624-6782) for a form.

Systematic Investing—Individual Shareholders Only

MainStay offers four automatic investment plans:

1. AutoInvest
   If you obtain authorization from your bank, you can automatically debit your designated bank account to:

   • make regularly scheduled investments;

   • and/or purchase shares whenever you choose.

2. Dividend or capital gains reinvestment
   Automatically reinvest dividends, distributions or capital gains and distributions from one MainStay Fund into the same Fund or the same Class of any other MainStay Fund. Funds established with dividend or capital gains reinvestment must meet the initial minimum investment amounts and any other eligibility requirements of the selected share class.

3. Payroll deductions
   If your employer offers this option, you can make automatic investments through payroll deduction.

4. Systematic exchange
   Automatically reinvest a share or dollar amount from one MainStay Fund into any other MainStay Fund. Funds established with a systematic exchange must meet the initial minimum investment amounts and any other eligibility requirements of the selected share class. Please see "Exchanging Shares Among MainStay Funds" for more information.

Systematic Withdrawal Plan—Individual Shareholders Only

Withdrawals must be at least $100. You must have at least $10,000 in your account for Investor Class and Class C shares at the time of the initial request and shares must not be in certificate form. The above minimums are waived for IRA and 403(b)(7) accounts where the systematic withdrawal represents required minimum distributions.

The Funds will not knowingly permit systematic withdrawals if, at the same time, you are making periodic investments.

Exchanging Shares Among MainStay Funds

You exchange shares when you sell all or a portion of shares in one MainStay Fund and use the proceeds to purchase shares of the same class of another MainStay Fund at NAV. Investment minimums and eligibility requirements apply to exchanges. An exchange of shares of one MainStay Fund for shares of another MainStay Fund will be treated as a sale of shares of the first MainStay Fund and as a purchase of shares of the second MainStay Fund. Any gain on the transaction may be subject to taxes. You may make exchanges from one MainStay Fund to another by phone. There is also a systematic exchange program that allows you to make regularly scheduled, systematic exchanges from one MainStay Fund to the same class of another MainStay Fund. When you redeem exchanged shares without a corresponding purchase of another MainStay Fund, you may have to pay any applicable contingent deferred sales charge. If you choose to sell Class C shares and then separately buy Investor Class or Class A shares, you may have to pay a deferred sales charge on the Class C shares, as well as pay an initial sales charge on the purchase of Investor Class or Class A shares.

You also may exchange shares of a MainStay Fund for shares of an identical class, if offered, of any series of certain other open-end investment companies sponsored, advised or administered by New York Life Investments or any affiliate thereof, which are offered in separate prospectuses, including:

You may not exchange shares of one MainStay Fund for shares of another MainStay Fund that is closed to new investors unless you are already a shareholder of that Fund. You may not exchange shares of one MainStay Fund for shares of another MainStay Fund that is closed to new share purchases or not offered for sale in your state.

Selling and exchanging shares may result in a gain or loss and therefore may be subject to taxes. Consult your tax adviser on the consequences.

Before making an exchange request, read the prospectus of the Fund you wish to purchase by exchange. You can obtain a prospectus for any MainStay Fund by contacting your broker, financial advisor or other financial institution or by calling the Funds at 800-MAINSTAY (624-6782).

The exchange privilege is not intended as a vehicle for short term trading, nor are the Funds designed for professional market timing organizations or other entities or individuals that use programmed frequent exchanges in response to market fluctuations. Excessive exchange activity may interfere with portfolio management and have an adverse effect on all shareholders (see "Excessive Purchases and Redemptions or Exchanges").

The Funds reserve the right to revise or terminate the exchange privilege, limit the amount or number of exchanges or reject any exchange consistent with the requirements of the 1940 Act and rules and interpretations of the SEC thereunder.

In certain circumstances you may have to pay a sales charge.

In addition, if you exchange Class C shares of a Fund into Class C shares of the MainStay Money Market Fund (which is offered in a separate prospectus) or you exchange Investor Class shares or Class A shares of a Fund subject to the 1.00% CDSC into Investor Class shares or Class A shares of the MainStay Money Market Fund, the holding period for purposes of determining the CDSC stops until you exchange back into Investor Class, Class A or Class C shares, as applicable, of another MainStay Fund.

When you exchange your shares, you may incur a redemption fee. Please see "Shareholder Guide—Redemption Fee" for more information.

MainStay Investments tries to make investing easy by offering a variety of programs to buy, sell and exchange Fund shares. These programs make it convenient to add to your investment and easy to access your money when you need it.

Excessive Purchases and Redemptions or Exchanges

The Funds are not intended to be used as a vehicle for excessive or short-term trading (such as market timing). The interests of a Fund's shareholders and the Fund's ability to manage its investments may be adversely affected by excessive purchases and redemptions or exchanges of Fund shares over the short term. When large dollar amounts are involved, excessive trading may disrupt efficient implementation of a Fund's investment strategies or negatively impact Fund performance. For example, the Manager or a Fund's Subadvisor might have to maintain more of a Fund's assets in cash or sell portfolio securities at inopportune times to meet unanticipated redemptions. By realizing profits through short-term trading, shareholders that engage in excessive purchases and redemptions or exchanges of Fund shares may dilute the value of shares held by long-term shareholders. Funds investing in securities that are thinly traded, trade infrequently or are relatively illiquid (such as foreign securities, high-yield debt securities and small cap securities) may attract investors seeking to profit from short-term trading strategies that exploit the special valuation issues applicable to these types of holdings to a greater degree than other types of funds, and thus, may be more vulnerable to the risks associated with such activity. Accordingly, the Funds' Boards have adopted and implemented policies and procedures designed to discourage, detect and prevent frequent purchases and redemptions or exchanges of Fund shares in order to protect long-term Fund shareholders. These policies are discussed more fully below. There is the risk that the Funds' policies and procedures will prove ineffective in whole or in part to detect or prevent excessive or short-term trading. A Fund may change its policies or procedures at any time without prior notice to shareholders.

The Funds reserve the right to restrict, reject or cancel, without prior notice, any purchase or exchange order for any reason, including any purchase or exchange order accepted by any investor's financial intermediary firm. Any such rejection or cancellation of an order placed through a financial intermediary will occur, under normal circumstances, within one business day of the financial intermediary transmitting the order to the Funds. In addition, the Funds reserve the right to reject, limit, or impose other conditions (that are more restrictive than those otherwise stated in this prospectus) on purchases or exchanges or to close or otherwise limit accounts based on a history of frequent purchases and redemptions of Fund shares that could adversely affect a Fund or its operations, including those from any individual or group who, in the Funds' judgment, is likely to harm Fund shareholders. Pursuant to the Funds' policies and procedures, a Fund may permit short-term purchases or exchanges that it believes, in the exercise of its judgment, are not disruptive or harmful to the Fund's long-term shareholders. For example, transactions conducted through systematic investment or withdrawal plans and trades within a money market fund are not subject to the surveillance procedures. Exceptions are subject to the advance approval by the Funds' Chief Compliance Officer, among others, and are subject to Board oversight. Apart from trading permitted or exceptions granted in accordance with the Funds' policies and procedures, no Fund accommodates, nor has any arrangement to permit, frequent purchases and redemptions of Fund shares.

The Funds, through MainStay Investments and the Distributor, maintain surveillance procedures to detect excessive or short-term trading in Fund shares. As part of this surveillance process, the Funds examine transactions in Fund shares that exceed certain monetary thresholds or numerical limits within a specified period of time. The Funds also may consider the history of trading activity in all accounts known to be under common ownership, control or influence. To the extent identified under these surveillance procedures, a Fund will place a "block" on any account if, during any 60-day period, there is (1) a purchase or exchange into the account following a redemption or exchange from such account or (2) a redemption or exchange from the account following a purchase or exchange into such account. An account that is blocked will not be permitted to place future purchase or exchange requests for an additional 60-day period in that Fund. The Funds may modify their surveillance procedures and criteria from time to time without prior notice, as necessary or appropriate to improve the detection of excessive or short-term trading or to address specific circumstances. In certain instances when deemed appropriate, the Funds may rely on a financial intermediary to apply its market timing procedures to an omnibus account. In certain cases, these procedures may be less restrictive than the Funds' procedures. Routine allocation and rebalancing activities made by certain asset allocation programs, funds-of-funds, or other collective investment strategies may not be subject to the surveillance procedures if the manager of such strategies represent to the satisfaction of the Funds' Chief Compliance Officer that such investment programs and strategies are consistent with the Funds' objective of avoiding disruption due to market timing.

In addition to these measures, the Funds may from time to time impose a redemption fee on redemptions or exchanges of Fund shares made within a certain period of time in order to deter excessive or short-term trading and to offset certain costs associated with such trading, which fee is described under "Information on Fees—Redemption Fee."

While the Funds discourage excessive or short-term trading, there is no assurance that the Funds or their procedures will be able to effectively detect such activity or participants engaging in such activity, or, if it is detected, to prevent its recurrence. The Funds' ability to reasonably detect all such trading may be limited, for example, where the Funds must rely on the cooperation of and/or information provided by financial intermediaries or retirement plans or where the costs of surveillance on certain trading exceeds the anticipated benefit of such surveillance to Fund shareholders.

Determining the Funds' Share Prices ("NAV") and the Valuation of Securities

Fair Valuation and Portfolio Holdings Disclosure

Each Fund generally calculates the value of its investments (also known as its net asset value, or NAV) at the close of regular trading on the New York Stock Exchange (usually 4:00 pm Eastern time) every day the Exchange is open. The Funds do not calculate their NAVs on days on which the Exchange is closed. The net asset value per share for a class of shares is determined by dividing the value of a Fund's net assets attributable to that class by the number of shares of that class outstanding on that day. The value of a Fund's investments is generally based on current market prices. If current market values are not available or, in the judgment of the Manager, do not accurately reflect the fair value of a security, investments will be valued by another method that the Board believes in good faith accurately reflects fair value. Changes in the value of a Fund's portfolio securities after the close of trading on the principal markets in which the portfolio securities trade will not be reflected in the calculation of NAV unless the Manager, in consultation with the Subadvisor (if applicable), deems a particular event could materially affect the NAV. In this case, an adjustment in the valuation of the securities may be made in accordance with procedures adopted by the Board. A Fund may invest in portfolio securities that are primarily listed on foreign exchanges that trade on weekends or other days when the Fund does not price its shares. The NAV of a Fund's shares may change on days when shareholders will not be able to purchase or redeem shares.

The Board has adopted valuation procedures for the Funds and has delegated day-to-day responsibility for fair value determinations to the Funds' Valuation Committee. Determinations of the Valuation Committee are subject to review and ratification by the Board at its next scheduled meeting after the fair valuations are determined. Fair value determinations may be based upon developments related to a specific security or events affecting securities markets. Fair valuation involves subjective judgments, and it is possible that the fair value determined for a security may differ materially from the value that could be realized upon the sale of the security.

The Funds expect to use fair value pricing for securities actively traded on U.S. exchanges only under very limited circumstances. The Funds may use fair value pricing more frequently for foreign securities. Where foreign securities markets close earlier than U.S. markets, the value of the securities may be affected by significant events or volatility in the U.S. markets occurring after the close of those foreign securities markets. To account for this, fair valuation procedures of certain Funds include a procedure whereby foreign securities may be valued based on third-party vendor modeling tools to the extent available.

Portfolio Holdings Information

A description of the Funds' policies and procedures with respect to the disclosure of each of the Fund's portfolio securities holdings is available in the Funds' SAI. MainStay Funds will publish quarterly a list of each Fund's ten largest holdings and publish monthly a complete schedule of each Fund's portfolio holdings on the internet at mainstayinvestments.com . You may also obtain this information by calling toll-free 800-MAINSTAY (624-6782). Disclosure of each Fund's portfolio holdings is made available as of the last day of each calendar month, no earlier than 30 days after the end of the reported month. In addition, disclosure of each Fund's top ten holdings is made quarterly no earlier than 15 days after the end of each calendar quarter. The Funds' quarterly top ten holdings information is also provided in the Annual Report and Semi-Annual Report to Fund shareholders and in the quarterly holdings report to the SEC on Form N-Q.

Fund Earnings

Dividends and Interest

Most funds earn either dividends from stocks, interest from bonds and other securities, or both. A mutual fund, however, always pays this income to you as "dividends." The dividends paid by each Fund will vary based on the income from its investments and the expenses incurred by the Fund.

MainStay Investments reserves the right to automatically reinvest dividend distributions of less than $10.00.

When the Funds Pay Dividends

The Funds, except for Global Equity Yield Fund, declare and pay any dividends, to the extent income is available, at least once a year, typically in December. Global Equity Yield Fund declares and pays dividends quarterly. Dividends are normally paid on the last business day of the month after a dividend is declared. However, for administrative reasons, dividends that are to be paid at the end of a calendar quarter may be paid prior to the last business day of the month after a dividend is declared. You begin earning dividends the next business day after MainStay Investments receives your purchase request in good order.

Buy after the dividend payment. Avoid buying shares shortly before a dividend payment. Part of your investment may be returned in the form of a dividend, which may be taxable.

Capital Gains

The Funds earn capital gains when they sell securities at a profit.

How to Take Your Earnings

You may receive your portion of MainStay Fund earnings in one of seven ways. You can make your choice at the time of application, and change it as often as you like by notifying your financial advisor (if permitted) or MainStay Investments directly. The seven choices are:

1. Reinvest dividends and capital gains in:

   • the same Fund; or

   • another MainStay Fund of your choice (other than a Fund that is closed, either to new investors or to new share purchases).

2. Take the dividends in cash and reinvest the capital gains in the same Fund.

3. Take the capital gains in cash and reinvest the dividends in the same Fund.

4. Take a percentage of dividends or capital gains in cash and reinvest the remainder in the same Fund.

5. Take dividends and capital gains in cash.

6. Reinvest all or a percentage of the capital gains in another MainStay Fund (other than a Fund that is closed, either to new investors or to new share purchases) and reinvest the dividends in the original Fund.

7. Reinvest all or a percentage of the dividends in another MainStay Fund (other than a Fund that is closed, either to new investors or to new share purchases) and reinvest the capital gains in the original Fund.

If you do not make one of these choices on your application, your earnings will be automatically reinvested in the same class of shares of the same Fund.

If you prefer to reinvest dividends and/or capital gains in another Fund, you must first establish an account in that class of shares of the Fund. There is no sales charge on shares purchased through the automatic reinvestment of dividends or capital gains.

Understand the Tax Consequences

Most of Your Earnings are Taxable

Virtually all of the dividends and capital gains distributions you receive from the Funds are taxable, whether you take them as cash or automatically reinvest them. A Fund's realized earnings are taxed based on the length of time a Fund holds its investments, regardless of how long you hold Fund shares. If a Fund realizes long-term capital gains, the earnings distributions are taxed as long-term capital gains; earnings from short-term capital gains and income generated on debt investments and other sources are generally taxed as ordinary income upon distribution. The current long-term capital gains maximum tax rate of 15% is scheduled to increase to 20% after 2010. Earnings of a Fund will generally be a result of capital gains that may be taxed as either long-term capital gains or short-term capital gains (taxed as ordinary income). Earnings generated by interest received on fixed-income securities generally will be a result of income generated on debt investments and will be taxable as ordinary income.

For individual shareholders, a portion of the dividends received from the Funds may be treated as "qualified dividend income," which is currently taxable to individuals at a maximum rate of 15%, to the extent that such Funds receive qualified dividend income from domestic corporations and certain qualified foreign corporations and certain holding period and other requirements are met. The shareholder must also generally satisfy a more than 60-day holding period requirement with respect to each distribution of qualified dividends in order to qualify for the 15% rate on such distribution. For corporate shareholders, a portion of the dividends received from the Blended Funds may qualify for the corporate dividends received deduction. The favorable treatment of any qualified dividend income is scheduled to expire after 2010.

MainStay Investments will mail your tax report each year by February 15. This report will tell you which dividends and redemption proceeds should be treated as taxable ordinary income, which, if any, as tax-exempt income, and which, if any, as long-term capital gains.

The Funds may be required to withhold U.S. Federal income tax at the rate of 28% of all taxable distributions payable to you if you fail to provide the Funds with your correct taxpayer identification number or to make required certifications, or if you have been notified by the IRS that you are subject to backup withholding. Such withholding is not an additional tax and any amounts withheld may be credited against your U.S. Federal income tax liability.

Return of Capital

If a Fund's distributions exceed its income and capital gains realized in any year, such excess distributions will constitute a return of capital for federal income tax purposes. A return of capital generally will not be taxable to you at the time of the distribution, but will reduce the cost basis of your shares and result in a higher reported capital gain or a lower reported capital loss when you sell shares.

However, if a Fund has available capital loss carryforwards to offset its capital gains realized in any year, and its distributions exceed its income alone, all or a portion of the excess distributions may not be treated, for tax purposes, as a return of capital, and would be taxable to shareholders as ordinary income.

The Funds will normally distribute any capital gains to shareholders in December.

Exchanges

An exchange of shares of one MainStay Fund for shares of another will be treated as a sale of shares of the first MainStay Fund and a purchase of shares of the second MainStay Fund. Any gain on the transaction may be subject to taxation.

Seek professional assistance. Your financial adviser can help you keep your investment goals coordinated with your tax considerations. However, regarding tax advice, always rely on your tax adviser. For additional information on federal, state and local taxation, see the SAI.

Do not overlook sales charges. The amount you pay in sales charges reduces gains and increases losses for tax purposes.

Who Runs the Funds' Day-to-Day Business?

The Board of Trustees of MainStay Funds Trust (the "Board"), oversees the actions of the Manager, the Subadvisor and the Distributor and decides on general policies governing the operations of the Funds. The Board also oversees the Funds' officers, who conduct and supervise the daily business of the Funds.

New York Life Investment Management LLC ("New York Life Investments" or "Manager"), 51 Madison Avenue, New York, New York 10010, serves as the Funds' Manager. In conformity with the stated policies of the Funds, New York Life Investments administers each Fund's business affairs and manages the investment operations of each Fund and the composition of the portfolio of each Fund, subject to the supervision of the Board. The Manager commenced operations in April 2000 and is an indirect, wholly-owned subsidiary of New York Life.

The Manager provides offices, conducts clerical, recordkeeping and bookkeeping services, and keeps most of the financial and accounting records required for the Funds. The Manager has delegated its portfolio management responsibilities for the Funds to the Subadvisor and is responsible for supervising the Subadvisor in the execution of its responsibilities.

The Manager also pays the salaries and expenses of all personnel affiliated with the Funds, except for the independent members of the Board, and all operational expenses that are not the responsibility of the Funds, including the fees paid to the Subadvisor. Pursuant to a management contract with each Fund, the Manager is entitled to receive fees from each Fund, accrued daily and payable monthly.

As the Funds have not commenced operations as of the date of this prospectus, they have not paid any management fees to New York Life Investments.

Information regarding the Board's approval of the investment management contract and subadvisory contract for each Fund will be found in the Fund's Annual Report for the fiscal year ended December 31, 2009.

The Manager is not responsible for records maintained by the Funds' Subadvisor, custodian, transfer agent or dividend disbursing agent except to the extent expressly provided in the Management Agreement between the Manager and the Fund.

Pursuant to an agreement with New York Life Investments, State Street Bank and Trust Company, One Lincoln Street, Boston, Massachusetts 02111-2900 ("State Street") provides sub-administration and sub-accounting services for the Funds. These services include calculating daily net asset values of the Funds, maintaining general ledger and sub-ledger accounts for the calculation of the Funds' respective net asset values, and assisting New York Life Investments in conducting various aspects of the Funds' administrative operations. For providing these services to the Funds, State Street is compensated by New York Life Investments.

Who Manages Your Money?

New York Life Investments serves as Manager of the assets of the Funds. New York Life Investments, a Delaware limited liability company, commenced operations in April 2000. New York Life Investments is an indirect, wholly-owned subsidiary of New York Life. As of June 30, 2009, New York Life Investments and its affiliates managed approximately $236 billion in assets.

Section 15(c) of the 1940 Act requires that all contracts pursuant to which persons serve as investment advisers to investment companies be approved by shareholders. As interpreted, this requirement also applies to the appointment of subadvisors to the Funds. The Manager and the Funds have obtained an exemptive order (the "Order") from the SEC permitting the Manager, on behalf of a Fund and subject to the approval of the Board, including a majority of the Independent Directors/Trustees, to hire or terminate unaffiliated subadvisors and to modify any existing or future sub-advisory agreement with unaffiliated subadvisors without shareholder approval. This authority is subject to certain conditions. Each Fund will notify shareholders and provide them with certain information required by the Order within 90 days of hiring a new subadvisor. Please see the Statement of Additional Information for more information on the Order. The initial sole shareholder of each Fund has approved the manager-of-managers arrangement.

The fees paid to the Subadvisor are paid out of the management fee paid to the Manager and are not additional expenses of each Fund.

Under the supervision of the Manager, the Subadvisor is responsible for making the specific decisions about buying, selling and holding securities; selecting brokers and brokerage firms to trade for them; maintaining accurate records; and, if possible, negotiating favorable commissions and fees with the brokers and brokerage firms for the Funds. For these services, the Subadvisor is paid a monthly fee by the Manager, not the Funds. (See the SAI for a description of fees.)

Epoch Investment Partners, Inc. ("Epoch"), 640 Fifth Avenue, 18th Floor, New York, New York 10019, serves as the Subadvisor to the Funds. Epoch was founded in April 2004 as a Delaware corporation. As of June 30, 2009, the firm managed approximately $7.8 billion in assets.

Portfolio Managers:

The Subadvisor uses a team of portfolio managers and analysts acting together to manage each Fund's investments. The senior members of each Fund's portfolio management team who are jointly and primarily responsible for the Fund's day-to-day management are set forth below.

Portfolio Manager Biographies:

The following section provides biographical information about each of the Fund's portfolio managers and certain other investment personnel. Additional information regarding the portfolio managers' compensation, other accounts managed by these portfolio managers and their ownership of shares of the Funds each manages is available in the SAI.

The financial highlights tables are intended to help you understand the Funds' financial performance for the period of the Funds' operations. Certain information reflects financial results for a single Fund share. The total returns in the tables represent the rate that an investor would have earned or lost on an investment in the Funds (assuming reinvestment of all dividends and capital gain distributions and excluding sales charges).

The financial highlights for MainStay Epoch U.S. Equity Fund, MainStay Epoch Global Choice Fund, MainStay Epoch Global Equity Yield Fund and MainStay Epoch International Small Cap Fund reflect the historical financial highlights of the Epoch U.S. Large Cap Equity Fund, Epoch U.S. All Cap Equity Fund, Epoch Global Equity Shareholder Yield Fund and Epoch International Small Cap Fund, each a separate series of The World Funds, Inc. (the "Epoch Funds"), respectively. Upon completion of the reorganizations of the Epoch Funds with and into the Funds, expected on or about [November 18, 2009], the Class A and Class I shares of the Funds will assume the performance, financial and other historical information of the Class P shares and Institutional Class shares of the Epoch Funds, respectively.

The information for the fiscal years ended December 31, 2005 through 2008 has been audited by Tait, Weller Baker LLP, whose report, along with the Funds' financial statements (when they were the Epoch Funds), are included in the annual reports of the Epoch Funds, which are available upon request.
