GOALS, STRATEGIES & RISKS

AEW Real Estate Fund


Adviser:	AEW Capital Management, L.P. (“AEW”)

Manager:	Matthew A. Troxell

Ticker Symbol:	Class A	Class B	Class C
	NRFAX	NRFBX	NRCFX

Investment Goal

The Fund seeks to provide investors with above-average income and long-term growth of capital. The Fund’s investment goal is non-fundamental, which means it may be changed without shareholder approval. The Fund will provide 60 days’ prior written notice to shareholders before changing the investment goal.

Principal Investment Strategies

Under normal market conditions, the Fund will invest at least 80% of its net assets (plus any borrowings made for investment purposes) in securities of real estate investment trusts (“REITs”) and/or real estate-related companies. In accordance with applicable Securities and Exchange Commission (“SEC”) requirements, the Fund will notify shareholders prior to any change to such policy taking effect. REITs are generally dedicated to owning, and usually operating, income-producing real estate, or dedicated to financing real estate. The Fund primarily invests in equity REITs, which own or lease real estate and derive their income primarily from rental income. Real estate-related companies are those companies whose principal activity involves the development, ownership, construction, management or sale of real estate; companies with significant real estate holdings; and companies that provide products or services related to the real estate industry.

AEW employs a value-oriented investment strategy designed to identify securities that are priced below what it believes is their intrinsic value. AEW believes that ultimately the performance of real estate equity securities is dependent upon the performance of the underlying real estate assets and company management as well as the overall influence of capital markets. Consequently, when selecting securities for the Fund, AEW draws upon the combined expertise of its securities, real estate and research professionals.

When selecting investments for the Fund, AEW generally considers the following factors that it believes help to identify those companies whose shares represent the greatest value and price appreciation potential:

Valuation: AEW has developed a proprietary model to assess the relative value of each stock in the Fund’s investment universe. This model is designed to estimate what an issuer’s anticipated cash flows are worth to a stock investor (a capital markets value) and to a direct real estate investor (a real estate value). The model helps AEW to identify stocks that it believes trade at discounts to either or both of these model values relative to similar stocks. AEW will generally sell a security once it is considered overvalued or when AEW believes that there is greater relative value in other securities in the Fund’s investment universe.

Price: AEW examines the historic pricing of each company in the Fund’s universe of potential investments. Those stocks that have underperformed in price, either in absolute terms or relative to the Fund’s investment universe in general, are typically of greater interest, provided AEW can identify and disagree with the sentiment that caused the underperformance.

Income: AEW further evaluates companies and REITs by analyzing their dividend yields as well as other factors that influence the sustainability and growth of dividends. These factors include cash flow, leverage and payout ratios.

Catalysts: When evaluating a security, AEW also seeks to identify potential catalysts that, in its opinion, could cause the marketplace to re-value the security upwards in the near term. These catalysts can be macro-economic, market-driven or company-specific in nature.

GOALS, STRATEGIES & RISKS

As a temporary defensive measure, the Fund may hold any portion of its assets in cash (U.S. Dollars, foreign currencies or multinational currency units) and/or invest in money market instruments or high quality debt securities AEW deems appropriate. The Fund may miss certain investment opportunities if it uses such defensive strategies and thus may not achieve its investment goal.

Principal Investment Risks

The principal risks of investing in the Fund are described below. There are other circumstances (including non-principal risks that are not described here) which could prevent the Fund from achieving its investment goal. The Fund does not represent a complete investment program. The Fund’s net asset value may fluctuate substantially over time. You may lose money by investing in the Fund.

Equity securities risk: Securities of real estate-related companies and REITs in which the Fund may invest may be considered equity securities, thus subjecting the Fund to the risks of investing in equity securities generally. This means that you may lose money on your investment due to sudden, unpredictable drops in value or periods of below-average performance in a given stock or in the stock market as a whole. The value of the Fund’s investments in equity securities is subject to the risks of unpredictable declines in the value of individual securities, industries and periods of below-average performance in individual securities, industries or in the equity market as a whole. Equity securities may include common stocks, preferred stocks, warrants, securities convertible into common or preferred stocks and other equity-like interests in an entity. Common stocks represent an equity or ownership interest in an issuer. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s bonds and preferred stock take precedence over the claims of those who own common stock. Equity securities may take the form of stock in corporations, limited partnership interests, interests in limited liability companies, REITs or other trusts and other similar securities.

Management risk: The risk that a strategy used by the Fund’s portfolio managers may fail to produce the intended result.

Market risk: The risk that the market value of a security may move up and down, sometimes rapidly and unpredictably, based upon a change in an issuer’s financial condition, as well as overall market and economic conditions.

REITs risk: Because the Fund concentrates its investments in the real estate industry, the Fund’s performance will be dependent in part on the performance of the real estate market and the real estate industry in general. The real estate industry is particularly sensitive to economic downturns. Securities of companies in the real estate industry, including REITs, are sensitive to factors such as changes in real estate values, property taxes, interest rates, cash flow of underlying real estate assets, occupancy rates, government regulations affecting zoning, land use and rents, and the management skill and creditworthiness of the issuer. Companies in the real estate industry may also be subject to liabilities under environmental and hazardous waste laws. In addition, the value of a REIT is affected by changes in the value of the properties owned by the REIT or securing mortgage loans held by the REIT. REITs are dependent upon cash flow from their investments to repay financing costs and also on the ability of the REITs’ managers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Small-cap companies risk: Companies in the real estate industry, including REITs, in which the Fund may invest may have relatively small market capitalizations. Small-cap companies and REITs, which AEW considers to be those with market capitalizations of $1 billion or less, tend to have more limited markets and resources than companies with larger market capitalizations. Consequently, share prices of small-cap companies and REITs can be more volatile than, and perform differently from, larger company stocks. As a result, it may be relatively more difficult for the Fund to buy and sell securities of small-cap companies.

The bar chart shows the Fund’s total returns for Class A shares for each calendar year since its first full year of operations. The returns for Class B and Class C shares differ from the Class A returns shown in the bar chart to the extent their respective expenses differ. The chart does not reflect any sales charge that you may be required to pay when you buy or redeem the Fund’s shares. A sales charge will reduce your return.

LOGO

The Fund’s Class A shares total return year to date as of March 31, 2009 was -31.78%.

The table below shows how the Fund’s average annual total returns for Class A, Class B and Class C shares (before and after taxes for Class A) for the one-year, five-year and since inception periods compare to those of the MSCI US REIT Index, an unmanaged index of the most actively traded REITs, designed to measure real estate equity performance. You may not invest directly in an index. The Fund’s total returns reflect, on a class by class basis, its expenses and the maximum sales charges that you may be required to pay when you buy or redeem the Fund’s shares. Class A total returns have also been calculated to reflect return after taxes on distributions only and also return after taxes on distributions and sales of Fund shares. The MSCI US REIT Index returns have not been adjusted for ongoing management, distribution and operating expenses and sales charges applicable to mutual fund investments.


Average Annual Total Returns (for the periods ended December 31, 2008)	Past 1 Year		Past 5 Years		Since Class Inception (12/29/00)
AEW Real Estate Fund
Class A – Return Before Taxes	-40.79	%	-0.10	%	5.89	%

Class C – Return Before Taxes	-38.26	%	0.34	%	5.91	%
MSCI US REIT Index**	-37.97	%	0.67	%	6.49	%

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans, qualified plans, education savings accounts, such as 529 plans, or individual retirement accounts. The after-tax returns are shown for only one class of the Fund. After-tax returns for the other classes of the Fund will vary. In some cases the after-tax returns may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of fund shares at the end of the measurement period.

**	The returns of the index do not reflect a deduction for fees, expenses or taxes. The returns of the index are calculated from January 1, 2001.

GOALS, STRATEGIES & RISKS

Delafield Select Fund


Adviser:	Reich & Tang Asset Management, LLC (“Reich & Tang”)

Managers:	J. Dennis Delafield, Charles W. Neuhauser, Vincent Sellecchia and Donald Wang

Ticker Symbol:	Class A	Class C
	DESAX	DESCX

Investment Goal

The Fund’s primary investment goal is to achieve long-term capital appreciation by investing in a focused group of common stocks issued primarily by small and mid-sized U.S. companies. Current income is a secondary objective. The Fund’s investment goal is non-fundamental, which means that it may be changed without shareholder approval. The Fund will provide 60 days’ prior written notice to shareholders before changing the investment goal.

Principal Investment Strategies

Under normal circumstances, the Fund will invest in a focused group of 12 to 25 common stocks issued primarily by small to mid-sized U.S. companies that Reich & Tang believes represent the best equity investment opportunities identified by Reich & Tang. To a lesser extent, the Fund may invest in other securities, including obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities.

The Fund applies a “value approach” to investing, seeking to invest in common stocks that Reich & Tang believes are currently undervalued by the market or that represent special situations. When selecting securities for the Fund, Reich & Tang considers factors such as the valuation of individual securities relative to other investment alternatives, trends in corporate profits, corporate cash flow, balance sheet changes, management capability and practices and the economic and political outlook. Although the strengths of a company’s balance sheet are important to Reich & Tang’s analysis, the Fund may invest in financially troubled companies if Reich & Tang has reason to believe that the company, based on its analysis, is worth more than the market price of the shares. In addition, companies generating free cash flow (defined as earnings, depreciation and deferred income tax in excess of the need for capital expenditures and dividends) will generally be considered attractive. Investment securities may also be assessed upon their earning power, stated asset values and off-balance sheet values. Reich & Tang may dispose of a security (i) if the price of the security increases above Reich & Tang’s target price for that security, (ii) if Reich & Tang believes that other investment opportunities offer the potential for greater capital appreciation or otherwise represent a better relative value, (iii) a company’s balance sheet weakens, (iv) company management is not executing its business plan, (v) Reich & Tang believes that actual or potential deterioration in the issuer’s earning power may adversely affect the price of its securities or (vi) the economic or political outlook for a company changes.

The Fund is non-diversified under the 1940 Act, which means that the Fund is not limited under the 1940 Act to a percentage of its assets that it may invest in any one issuer. Because the Fund intends to invest in the securities of a limited number of issuers, an investment in the Fund may involve a higher degree of risk than would be present in a diversified portfolio.

The Fund will normally not seek to realize profits by anticipating short-term market movements and, under ordinary circumstances, intends to purchase securities for long-term capital appreciation.

As a temporary defensive measure, the Fund may hold any portion of its assets in cash (U.S. Dollars, foreign currencies or multinational currency units) and/or invest in money market instruments or high quality debt securities as Reich & Tang deems appropriate. The Fund may miss certain investment opportunities if it uses defensive strategies and thus may not achieve its investment goal.

GOALS, STRATEGIES & RISKS

Principal Investment Risks

Management risk: The risk that a strategy used by the Fund’s portfolio managers may fail to produce the intended result.

Non-diversification risk: Compared with diversified mutual funds, the Fund may invest a greater percentage of its assets in a particular issuer and may invest in fewer issuers. Therefore, the Fund may have more risk because changes in the value of a single security or the impact of a simple economic, political or regulatory occurrence may have a greater adverse impact on the Fund’s net asset value.

Small- and middle-capitalization companies risk: Investments in small- and middle-capitalization companies carry special risks, including narrower markets, more limited financial and management resources, less liquidity and greater volatility than large company securities. Investing in small-cap and mid-cap companies may involve greater risk than investing in larger companies since small- and mid-cap companies tend to be more susceptible to adverse business events or economic downturns, are less liquid and more thinly traded and are subject to greater price volatility.

For additional information, see the section “More About Risk.”

Evaluating the Fund’s Past Performance

The bar chart and table shown below give an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for the one-year, five-year and ten-year periods compare with those of a broad measure of market performance. The returns shown in the bar chart and table include performance for the Fund’s predecessor, the Reich & Tang Concentrated Portfolio L.P. (the “Predecessor Delafield Fund”), a Delaware limited partnership whose assets and liabilities the Fund acquired in a reorganization that occurred at the close of business on September 26, 2008 (the “Reorganization”). See “Performance Information” in the Fund’s Statement of Additional Information (“SAI”). In the Reorganization, limited partners of the Predecessor Delafield Fund received Class Y shares of the Fund, which are offered in a different prospectus. The Predecessor Delafield Fund was managed using substantially the same investment objectives, policies and restrictions as those used by the Fund. However, the Predecessor Delafield Fund was not registered as an investment company with the SEC. Therefore, it was not subject to the investment restrictions imposed by law on registered mutual funds. If the Predecessor Delafield Fund had been registered, its performance may have been adversely affected. The Fund’s past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

The bar chart below shows the Fund’s total returns for Class Y shares for each of the last ten calendar years.† Although Class A and Class C shares and Class Y shares would have similar returns (because all of the Fund’s shares represent interests in the same portfolio of securities), Class A and Class C performance would be lower than Class Y performance because of the lower expenses and no sales charges paid by Class Y shares.

The table below shows how average annual total returns for Class A, Class C and Class Y shares of the Fund (before and after taxes for Class Y) for the one-year, five-year and ten-year periods compare to that of the Russell 2500 Index. The Russell 2500 Index is an unmanaged index that measures the 2500 smallest companies in the Russell 3000 Index. It is a popular indicator of the performance of the small to mid-cap segment of the U.S. stock market. You may not invest directly in an index. The Fund’s total returns reflect, on a class by class basis, its expenses and the maximum sales charges that you may be required to pay when you buy or redeem the Fund’s shares. Class Y total returns have also been calculated to reflect return after taxes on distributions only and return after taxes on distributions and sales of Fund shares. The Russell 2500 Index returns have not been adjusted for ongoing management, distribution and operating expenses and sales charges applicable to mutual fund investments.

Hansberger International Fund


Adviser:	Natixis Asset Management Advisors, L.P. (“Natixis Advisors”)

Subadviser:	Hansberger Global Investors, Inc. (“Hansberger”)

Managers:	Growth Segment: Trevor Graham, Barry A. Lockhart, Patrick H. Tan and Thomas R.H. Tibbles Value Segment: Ronald Holt and Lauretta Reeves

Ticker Symbol:	Class A	Class B	Class C
	NEFDX	NEDBX	NEDCX

Investment Goal

The Fund seeks long-term growth of capital. The Fund’s investment goal is non-fundamental, which means it may be changed without shareholder approval. The Fund will provide 60 days’ prior written notice to shareholders before changing the investment goal.

Principal Investment Strategies

The Fund seeks to attain its goal by investing substantially all of its assets in equity securities. The Fund is an international mutual fund, which means that it seeks to invest a significant portion of its net assets in equity securities of companies located outside the United States. The Fund invests in small-, mid-, and large-capitalization companies and expects to invest its assets across developed and emerging markets in Eastern and Western Europe, Asia and the Americas.

The Fund may also:

•

Invest in convertible preferred stock and convertible debt securities.

•

Invest up to 35% of its assets in fixed-income securities, including government bonds as well as lower-quality debt securities.

As a temporary defensive measure, the Fund may hold any portion of its assets in cash (U.S. Dollars, foreign currencies or multinational currency units) and/or invest in money market instruments or high quality debt securities as Hansberger deems appropriate. The Fund may miss certain investment opportunities if it uses such defensive strategies and thus may not achieve its investment goal.

Subject to the allocation policy adopted by the Board of Trustees, Natixis Advisors generally allocates capital invested in the Fund equally between its two segments, which are managed by the subadviser as described below. Under the allocation policy, Natixis Advisors may also allocate capital away or towards a segment from time to time.

Growth Segment: In managing this segment, Hansberger follows a flexible investment policy that allows it to select those investments it believes are best suited to achieve the Fund’s investment objective over the long-term, using a disciplined, long-term approach to international investing. The growth segment will primarily invest in the equity securities of companies organized or headquartered outside of the United States. This segment will invest in at least three different countries and expects to be invested in more than three countries, including countries considered to be emerging market countries. In general, Hansberger seeks companies with the following characteristics, although not all of the companies selected will have these attributes:

•

High secular growth

•

Superior profitability

•

Medium to large capitalizations, although there are no limitations on the size of the companies in which the segment may invest

In making investment decisions, Hansberger generally employs the following methods:

•

Securities are selected on the basis of fundamental company-by-company analysis.

Natixis Equity Funds

Prospectus – May 1, 2009

GOALS, STRATEGIES & RISKS

•

In choosing equity instruments, Hansberger will typically focus on the market price of a company’s securities relative to its evaluation of the company’s long-term earnings and cash flow potential.

•

In addition, a company’s valuation measures, including but not limited to price-to-earnings ratio and price-to-book ratio, will customarily be considered.

•

Hansberger seeks to control portfolio risk through top-down geographic and sector allocation.

Hansberger generally sells a security if its price target is met, the company’s fundamentals change, or if the Fund is fully invested and a better investment opportunity arises.

Value Segment: In managing this segment, Hansberger employs an intensive fundamental approach to selecting stocks. Hansberger seeks to identify stocks with a market value that is believed to be less than a company’s intrinsic value, based on its long-term potential. Hansberger’s investment approach integrates extensive research (both internal and external), proprietary valuation screens, and fundamental analysis of stocks with a long-term investment perspective. This analysis involves evaluating a company’s prospects by focusing on such factors as the quality of a company’s management, the competitive position of a company within its industry, the financial strength of the company, the quality and growth potential of its earnings, and the outlook for the company’s future based on these and other similar factors. Hansberger will also consider other factors in its analysis, including country and political risks as well as economic and market conditions.

Hansberger seeks to broaden the scope and increase the effectiveness of its fundamental analysis by searching for undervalued stocks in many countries around the world, including emerging markets. This global search provides Hansberger with more diverse opportunities and with the flexibility to shift portfolio investments, not only from company to company and industry to industry, but also from country to country, in search of undervalued stocks. Hansberger’s objective is to identify undervalued securities, to hold them for the long-term, and to achieve long-term capital growth as the marketplace realizes the value of these securities over time. Hansberger expects to typically invest in 70 to 80 stocks (for this segment), across a broad spectrum of market capitalizations. In terms of both industry representation and capitalization, the segment’s holdings may differ significantly from those of the typical international equity fund. A stock is generally sold when its share price rises above sell target and superior alternatives are found. Additionally, when selling a stock, Hansberger may take into account the issuer’s structural company and industry specific factors, changes in shareholder orientation (for example, a shift from treating all shareholders fairly to disadvantaging minority shareholders), and the company’s management.

Principal Investment Risks

Currency Risk: The risk that fluctuations in the exchange rates between different currencies may negatively affect an investment.

Emerging markets risk: The risk associated with investing in companies traded in developing securities markets, which may be smaller and have shorter operating histories than companies in developed markets. Emerging markets involve risks in addition to and greater than those generally associated with investing in developed foreign markets. The extent of economic development, political stability, market depth, infrastructure and capitalization, and regulatory oversight in emerging market economies is generally less than in more developed markets.

GOALS, STRATEGIES & RISKS

growth stocks during any given period. Equity securities may include common stocks, preferred stocks, warrants, securities convertible into common or preferred stocks and other equity-like interests in an entity. Common stocks represent an equity or ownership interest in an issuer. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s bonds and preferred stock take precedence over the claims of those who own common stock. Equity securities may take the form of stock in corporations, limited partnership interests, interests in limited liability companies, REITs or other trusts and other similar securities.

Foreign securities risk: The risk associated with investments in issuers located in foreign countries. The Fund’s investments in foreign securities may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. The securities markets of many foreign countries are relatively small, with a limited number of issuers and a small number of securities. In addition, foreign companies often are not subject to the same degree of regulation as U.S. companies. Reporting, accounting and auditing standards of foreign countries differ, in some cases significantly, from U.S. standards. Nationalization, expropriation or confiscatory taxation, currency blockage, political changes or diplomatic developments can cause the value of the Fund’s non-U.S. investments to decline. In the event of nationalization, expropriation or other confiscation, the Fund could lose its entire foreign investment.

Management risk: The risk that a strategy used by the Fund’s portfolio managers may fail to produce the intended result.

For additional information, see the section “More About Risk.”

Evaluating the Fund’s Past Performance

Prior to March 1, 2004, the Fund had multiple subadvisers, including the current subadviser. The performance results shown below, for the periods prior to March 1, 2004, reflect results achieved by those multiple subadvisers. The Fund’s performance might have been different had the current advisory arrangements and investment strategies been in place for all periods shown.

The bar chart shows the Fund’s total returns for Class A shares for each of the last ten calendar years. The returns for Class B and Class C shares differ from the Class A returns shown in the bar chart to the extent their respective expenses differ. The chart does not reflect any sales charge that you may be required to pay when you buy or redeem the Fund’s shares. A sales charge will reduce your return.

Harris Associates Large Cap Value Fund


Adviser:	Natixis Asset Management Advisors, L.P. (“Natixis Advisors”)

Managers:	Edward S. Loeb, Michael J. Mangan and Diane L. Mustain

Ticker Symbol:	Class A	Class B	Class C
	NEFOX	NEGBX	NECOX

Investment Goal

The Fund seeks opportunities for long-term capital growth and income. The Fund’s investment goal is non-fundamental, which means it may be changed without shareholder approval. The Fund will provide 60 day’s prior written notice to shareholders before changing the investment goal.

Principal Investment Strategies

Under normal market conditions, the Fund will invest substantially all of its assets in common stock of large- and mid-capitalization companies in any industry. The Fund will invest at least 80% of its net assets (plus any borrowings made for investment purposes) in companies that have market capitalizations within the capitalization range of the Russell 1000 Index, a nationally recognized index of large-cap companies. In accordance with applicable SEC requirements, the Fund will notify shareholders prior to any change to such policy taking effect.

Harris Associates uses a value investment philosophy in selecting equity securities. This philosophy is based upon the belief that, over time, a company’s stock price converges with the company’s true business value. By “true business value,” Harris Associates means its estimate of the price a knowledgeable buyer would pay to acquire the entire business. Harris Associates believes that investing in securities priced significantly below their true business value presents the best opportunity to achieve the Fund’s investment objectives.

The Fund may also:

•

Invest in foreign securities traded in U.S. markets (through American Depositary Receipts (“ADRs”) or non-U.S. stocks traded in U.S. markets). ADRs are securities issued by a U.S. bank that represent shares of a foreign company.

As a temporary defensive measure, the Fund may hold any portion of its assets in cash (U.S. Dollars, foreign currencies or multinational currency units) and/or invest in money market instruments or high quality debt securities as Harris Associates deems appropriate. The Fund may miss certain investment opportunities if it uses defensive strategies and thus may not achieve its investment goal.

Principal Investment Risks

GOALS, STRATEGIES & RISKS

the risk that their lower valuations fairly reflect their business prospects or that other investors will not agree that the stocks represent favorable investment opportunities, and they may fall out of favor with investors and underperform growth stocks during any given period. Equity securities may include common stocks, preferred stocks, warrants, securities convertible into common or preferred stocks and other equity-like interests in an entity. Common stocks represent an equity or ownership interest in an issuer. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s bonds and preferred stock take precedence over the claims of those who own common stock. Equity securities may take the form of stock in corporations, limited partnership interests, interests in limited liability companies, REITs or other trusts and other similar securities.

Foreign securities risk: This is the risk associated with investments in issuers located in foreign countries. The Fund’s investments in foreign securities may experience more rapid and extreme changes in value than investments in securities of U.S. companies. The securities markets of many foreign countries are relatively small, with a limited number of issuers and a small number of securities. In addition, foreign companies often are not subject to the same degree of regulation as U.S. companies. Reporting, accounting and auditing standards of foreign countries differ, in some cases significantly, from U.S. standards. Nationalization, expropriation or confiscatory taxation, currency blockage, political changes or diplomatic developments can cause the value of the Fund’s non-U.S. investments to decline. In the event of nationalization, expropriation, or other confiscation, the Fund could lose its entire foreign investment. Investments in emerging markets may be subject to these risks to a greater extent than those in more developed markets.

Management risk: The risk that a strategy used by the Fund’s portfolio managers may fail to produce the intended result.

For additional information, see the section “More About Risk.”

Investment Goal

Principal Investment Strategies

Natixis Advisors believes that this Fund’s multi-manager approach to equity investing — which combines the varied styles of multiple subadvisers in selecting securities for each of the Fund’s four segments — offers uncommon diversification and a different investment opportunity than funds managed by a single adviser using a single style. Natixis Advisors believes that having several subadvisers with varying and successful management styles may increase the likelihood that the Fund will produce better returns for its shareholders with less variability of return and less risk of persistent underperformance than a fund managed by a single adviser.

Subject to the allocation policy adopted by the Fund’s Board of Trustees, Natixis Advisors generally allocates capital invested in the Fund equally among its four segments which are managed by the subadvisers set forth above. Under the allocation policy, Natixis Advisors may also allocate capital away or towards one or more segment from time to time and may reallocate capital among the segments. Each subadviser manages its segment (or segments in the case of Loomis Sayles) of the Fund’s assets in accordance with its distinct investment style and strategy.

The Fund ordinarily invests substantially all of its assets in equity securities. Under normal market conditions, the Fund will invest at least 80% of its net assets (plus any borrowings made for investment purposes) in securities of U.S. issuers. In accordance with applicable SEC requirements, the Fund will notify shareholders prior to any change to such policy taking effect.

The Fund may also:

•

Invest in securities offered in initial public offerings (“IPOs”) and Rule 144A securities.

•

Invest in convertible preferred stock and convertible debt securities.

•

Invest in REITs.

•

Invest in fixed-income securities, including U.S. government bonds and lower-quality corporate bonds.

•

Hold securities of foreign issuers traded over the counter or on foreign exchanges, including securities in emerging markets and related currency hedging transactions.

•

Invest in options and enter into futures, swap contracts, currency transactions and other derivatives.

•

Engage in active and frequent trading of securities and other instruments. Effects of frequent trading may include high transaction costs, which may lower the Fund’s returns, and realization of greater short-term capital gains, distributions of which are taxable to shareholders who are individuals as ordinary income. Trading costs and tax effects associated with frequent trading may adversely affect the Fund’s performance.

GOALS, STRATEGIES & RISKS

As a temporary defensive measure, the Fund may hold any portion of its assets in cash (U.S. Dollars, foreign currencies or multinational currency units) and/or invest in money market instruments or high quality debt securities as the subadvisers deem appropriate. The Fund may miss certain investment opportunities if it uses such defensive strategies and thus may not achieve its investment goal.

For more detailed information on each subadviser’s investment strategies, please refer to the section “Natixis U.S. Diversified Portfolio — More on Investment Strategies.”

Principal Investment Risks

Allocation risk: The Fund’s investment performance depends on how its assets are allocated. The allocation, as set forth above, may not be optimal in every market condition. You could lose money on your investment in the Fund as a result of this allocation.

Derivative instruments risk: Derivative instruments are subject to changes in the underlying securities or indices on which such transactions are based. There is no guarantee that the use of derivatives for hedging purposes will be effective or that suitable transactions will be available. Even a small investment in derivatives (which include options, futures, swap contracts and other transactions) may give rise to leverage risk, and can have a significant impact on the Fund’s exposure to stock market values, interest rates or currency exchange rates. Derivatives are also subject to credit risk and liquidity risk.

Equity securities risk: You may lose money on your investment due to unpredictable drops in a stock’s value or periods of below-average performance in a given stock or in the stock market as a whole. The value of the Fund’s investments in equity securities is subject to the risks of unpredictable declines in the value of individual securities and periods of below-average performance in individual securities or in the equity market as a whole. Securities issued in IPOs tend to involve greater market risk than other equity securities due, in part, to public perception and the lack of publicly available information and trading history. Rule 144A securities may be less liquid than other equity securities. Small capitalization and emerging growth companies may be subject to more abrupt price movements, limited markets and less liquidity than larger, more established companies, which could adversely affect the value of the Fund’s portfolio. Growth stocks are generally more sensitive to market movements than other types of stocks primarily because their stock prices are based heavily on future expectations. Growth stocks may underperform value stocks during any given period. Value stocks present the risk that their lower valuations fairly reflect their business prospects or that other investors will not agree that the stocks represent favorable investment opportunities, and they may fall out of favor with investors and underperform growth stocks during any given period. Equity securities may include common stocks, preferred stocks, warrants, securities convertible into common or preferred stocks and other equity-like interests in an entity. Common stocks represent an equity or ownership interest in an issuer. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s bonds and preferred stock take precedence over the claims of those who own common stock. Equity securities may take the form of stock in corporations, limited partnership interests, interests in limited liability companies, REITs or other trusts and other similar securities.

Fixed-income securities risk: Fixed-income securities are subject to credit risk, interest rate risk and liquidity risk. Generally, the value of fixed-income securities rises when prevailing interest rates fall and falls when interest rates rise. You may lose money on your investment due to unpredictable drops in a security’s value or periods of below-average performance in a given security or in the securities market as a whole. Lower-quality fixed-income securities (commonly known as “junk bonds”) may be subject to these risks to a greater extent than other fixed-income securities. These securities are considered predominantly speculative with respect to the issuer’s continuing ability to make principal and interest payments.

Natixis Equity Funds

Prospectus – May 1, 2009

GOALS, STRATEGIES & RISKS

Management risk: The risk that a strategy used by the Fund’s portfolio managers may fail to produce the intended result.

REITs risk: The real estate industry is particularly sensitive to economic downturns. Securities of companies in the real estate industry, including REITs, are sensitive to factors such as changes in real estate values, property taxes, interest rates, cash flow of underlying real estate assets, occupancy rates, government regulations affecting zoning, land use and rents, and the management skill and creditworthiness of the issuer. Companies in the real estate industry may also be subject to liabilities under environmental and hazardous waste laws. In addition, the value of a REIT is affected by changes in the value of the properties owned by the REIT or securing mortgage loans held by the REIT. REITs are dependent upon cash flow from their investments to repay financing costs and also on the ability of the REITs’ managers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Small-cap companies risk: Small-cap companies tend to have more limited markets and resources, and less liquidity, than companies with larger market capitalizations. Consequently, share prices of small-cap companies can be more volatile than, and perform differently from, larger capitalization company stocks.

For additional information, see the section “More About Risk.”

Evaluating the Fund’s Past Performance

The Fund uses multiple subadvisers. The performance results shown below reflect results achieved by previous subadvisers using different investment strategies. The Fund’s performance might have been different had the current subadvisory arrangements and investment strategies been in place for all periods shown.

Natixis U.S. Diversified Portfolio — More on Investment Strategies

The Fund’s portfolio is divided into four different segments managed by the three subadvisers set forth below. These subadvisers pursue the Fund’s overall goal by employing the strategies and techniques described below.

Natixis Equity Funds

Prospectus – May 1, 2009

GOALS, STRATEGIES & RISKS

BlackRock

The segment of the Fund managed by BlackRock, under normal conditions, pursues long-term growth of capital. The segment primarily invests in a portfolio of common stocks of U.S. companies. The companies selected by BlackRock for the segment typically have the following characteristics:

•

Market capitalizations of any size with emphasis on capitalizations greater than $2 billion

•

Above-average rates of earnings growth. Some, but not all of the factors that may contribute to above-average rates of earnings growth include:

•

Above-average growth rates in sales

•

Improvements in profit margins

•

Providing proprietary or niche products and services

•

Strong industry growth

•

A lead in market share

The segment may also invest in the securities of foreign companies, either directly or indirectly through depositary receipts, as well as securities convertible into securities of foreign companies.

In making investment decisions, BlackRock generally employs the following methods:

•

Investment ideas are generated through company visits, financial reports, external research and extensive in-house analysis.

•

The investment process assesses industry momentum and cycles as well as corporate revenue and earnings growth.

•

Industries are evaluated based on expectations of future earnings momentum and the confirmation of these expectations over time. BlackRock will usually sell a position if company fundamentals or management do not perform to expectations.

Harris Associates

Under normal circumstances, the segment of the Fund managed by Harris Associates will invest primarily in the common stocks of large- and mid-capitalization companies that Harris Associates believes are trading at a substantial discount to the company’s “true business value.” Harris Associates’ value-oriented investment philosophy is based upon its belief that over time a stock’s discounted market price and its true business value will converge. Harris Associates believes that this philosophy provides the best opportunity to achieve long-term capital growth while also protecting from downside risk. It therefore uses this philosophy to locate companies with the following characteristics, although not all of the companies selected by Harris Associates will have each of these attributes:

•

Stock selling at less than 60% of its intrinsic value

•

Favorable intrinsic value growth potential

•

Owner-oriented management

In making investment decisions, Harris Associates generally employs the following methods:

•

Harris Associates uses a fundamental bottom-up investment approach, which means that it focuses on individual companies rather than macro-economic factors or specific industries. Each company is analyzed on a case-by-case basis to select those that meet Harris Associates’ standards of quality and value.

•

Once Harris Associates determines that a stock trades at a significant discount to its true business value and has other attractive qualities such as a positive free cash flow, it will consider that stock for purchase by analyzing the quality and motivation of the company’s management as well as the company’s market position within its industry.

•

Investments are continuously monitored by both analysts and Fund managers. Harris Associates will generally buy a stock when it believes the stock sells for a price below 60% of its true business value, and will generally sell a stock when it believes the stock price approaches 90% of its true business value.

GOALS, STRATEGIES & RISKS

Loomis Sayles — Mid Cap Growth segment

Under normal circumstances, the Mid Cap Growth segment of the Fund, which is one of two segments of the Fund managed by Loomis Sayles, will invest primarily in common stocks with market capitalizations, at the time of investment, within the capitalization range of companies included in the Russell Midcap Growth Index, an unmanaged index of midcap companies within the Russell 1000 Growth Index. Loomis Sayles seeks securities with the following characteristics, although not all of the companies selected by Loomis Sayles will have each of the attributes:

•

Distinctive products, technologies or services

•

Attractive valuation relative to both competitors and their own operating history

•

Strong management team

•

Competitive barriers to entry within the company’s industry

In making investment decisions, Loomis Sayles employs the following methods:

•

Loomis Sayles uses a bottom-up, fundamental research process to build the segment’s portfolio. This research consists of broad, in-depth coverage, including regular contact with company management, near- and long-term projections of company fundamentals and evaluations of potential earnings growth.

•

Loomis Sayles also seeks to understand how companies are affected by larger, industry-wide dynamics. Typically, it will invest a portion of the segment’s assets in companies that it believes are positioned to benefit from disruptive change in their industry or sector.

•

Analysts and Fund managers continuously monitor investments. The analysts and portfolio managers will evaluate the companies to determine whether they continue to possess the same fundamental characteristics for growth which made them candidates for the investment originally.

•

Loomis Sayles will generally sell a position if earnings or fundamentals deteriorate, if there is significant change in management or when more favorable opportunities arise.

Loomis Sayles — Small Cap Value segment

Under normal circumstances, the Small Cap Value segment of the Fund, the other segment of the Fund managed by Loomis Sayles, will invest primarily in common stocks with a market capitalization, at the time of the investment, within the range of the market capitalizations of those companies constituting the Russell 2500 Index. The Russell 2500 Index is an unmanaged index of the 2,500 smallest companies in the Russell 3000 Index. Loomis Sayles may also invest up to 35% of the Small Cap Value segment’s assets in companies with larger capitalization levels. Loomis Sayles seeks to achieve the objective of the Fund by emphasizing companies undervalued by the market in relation to earnings, dividends, assets, and growth prospects. This segment of the Fund is value-oriented with emphasis on security selection rather than sector rotation and market timing. The securities selected by Loomis Sayles for the segment typically have the following characteristics, although not all of the companies selected by Loomis Sayles will have each of the attributes:

•

Attractive valuations

•

Positive free cash flow

•

Strong balance sheets

•

Strong fundamental prospects

Loomis Sayles will build a core portfolio of companies which, in its opinion, possess the attributes set forth above. It also invests a smaller portion of the segment’s assets in companies which it believes are undergoing a “special situation” or turn-around. These types of companies may have experienced business problems but, in the opinion of Loomis Sayles, have favorable prospects for recovery.

In making investment decisions, Loomis Sayles generally employs the following methods:

•

Loomis Sayles uses a bottom-up, fundamental research process. This research consists of broad in-depth coverage, including contact with company management, near- and long-term projections of company fundamentals and evaluations of potential cash flow and earnings growth. The market capitalization of these companies will generally be within the range of the Russell 2500 Index.

Natixis Equity Funds

Prospectus – May 1, 2009

GOALS, STRATEGIES & RISKS

•

Loomis Sayles emphasizes smaller companies that it believes are undervalued by the market. Target valuations are determined by analysis of cash flow and earnings prospects of each company considered for the portfolio. Absolute valuation levels, as well as valuations versus a peer group, are considered.

•

Loomis Sayles builds a diversified portfolio across many economic sectors in an attempt to protect the value segment of the Fund against the inherent volatility of small capitalization companies.

Investment Goal

The Fund seeks capital appreciation. The Fund’s investment goal is non-fundamental, which means it may be changed without shareholder approval. The Fund will provide 60 day’s prior written notice to shareholders before changing the investment goal.

Principal Investment Strategies

The Fund, under normal market conditions, will invest at least 80% of its net assets (plus any borrowings made for investment purposes) in companies that, at the time of purchase, have market capitalizations within the capitalization range of the Russell 2000 Value Index, an unmanaged index that measures the performance of those Russell 2000 companies with lower price-to-book ratios and lower forecasted growth values. In accordance with applicable SEC requirements, the Fund will notify shareholders prior to any change to such policy taking effect. The Fund may, however, invest in companies with larger capitalizations.

Vaughan Nelson invests in small capitalization companies with a focus on absolute return. Vaughan Nelson uses a bottom-up value oriented investment process in constructing the Fund’s portfolio. Vaughan Nelson seeks companies with the following characteristics, although not all of the companies selected will have these attributes:

•

Companies earning a positive economic margin with stable-to-improving returns

•

Companies valued at a discount to their asset value

•

Companies with an attractive and sustainable dividend level.

In selecting investments for the Fund, Vaughan Nelson generally employs the following strategies:

•

Value-driven investment philosophy that selects stocks selling at a relatively low value based on discounted cash flow models. Vaughan Nelson selects companies that it believes are out-of-favor or misunderstood.

•

Vaughan Nelson starts with an investment universe of 5,000 securities. Vaughan Nelson then uses value-driven screens to create a research universe of companies with market capitalizations of at least $100 million.

•

Vaughan Nelson uses fundamental analysis to construct a portfolio of 60 to 80 securities consisting of quality companies in the opinion of Vaughan Nelson.

•

Vaughan Nelson will generally sell a stock when it reaches Vaughan Nelson’s price target, when the issuer shows a deteriorating financial condition, or when it has repeated negative earnings surprises.

The Fund may also:

•

Invest in convertible preferred stock and convertible debt securities.

•

Invest up to 35% of its assets in fixed-income securities, including U.S. government bonds as well as lower quality debt securities.

•

Invest in foreign securities, including those of emerging markets.

•

Invest in REITs.

Investment Goal

The Fund seeks long-term capital appreciation. The Fund’s investment goal is non-fundamental, which means it may be changed without shareholder approval. The Fund will provide 60 days’ prior written notice to shareholders before changing the investment goal.

Principal Investment Strategies

The Fund, under normal market conditions, will invest primarily in companies that, at the time of purchase, have market capitalizations within the capitalization range of the Russell Midcap Value Index ($50 million to $15.3 billion as of March 25, 2009) which measures the performance of the mid-cap value segment of the U.S. equity universe. The Russell Midcap Value Index is a market capitalization-weighted index of those companies within the broader Russell Midcap Index (which includes approximately 800 of the smallest companies included in the Russell 1000 Index) that exhibit lower price-to-book ratios and lower forecasted growth values. However, the Fund does not have any market capitalization limits and may invest in companies with smaller or larger capitalizations.

Vaughan Nelson invests in medium capitalization companies with a focus on absolute return. Vaughan Nelson uses a bottom-up value oriented investment process in constructing the Fund’s portfolio. Vaughan Nelson seeks companies with the following characteristics, although not all of the companies selected will have these attributes:

•

Companies earning a positive economic margin with stable-to-improving returns

•

Companies valued at a discount to their asset value.

•

Companies with an attractive and sustainable dividend level.

In selecting investments for the Fund, Vaughan Nelson generally employs the following strategies:

•

Vaughan Nelson employs a value-driven investment philosophy that selects stocks selling at a relatively low value based on business fundamentals, economic margin analysis and discounted cash flow models. Vaughan Nelson selects companies that it believes are out-of-favor or misunderstood.

•

Vaughan Nelson narrows the investment universe by using value-driven screens to create a research universe of companies with market capitalizations between $1 billion and $20 billion.

•

Vaughan Nelson uses fundamental analysis to construct a portfolio that it believes has attractive return potential.

•

Vaughan Nelson will generally sell a stock when it reaches Vaughan Nelson’s price target or when the issuer shows a deteriorating financial condition due to increased competitive pressures or internal or external forces reducing future expected returns.

The Fund may also:

•

Invest in convertible preferred stock and convertible debt securities.

•

Invest in foreign securities, including those of emerging markets.

•

Invest in other investment companies, to the extent permitted by the Investment Company Act of 1940.

Prospectus – May 1, 2009

GOALS, STRATEGIES & RISKS

•

Invest in REITs.

•

Invest in securities offered in initial public offerings (“IPOs”) and Rule 144A securities.

•

Engage in active and frequent trading of securities and other instruments. Effects of frequent trading may include high transaction costs, which may lower the Fund’s return, and realization of greater short-term capital gains, distributions of which are taxable to shareholders who are individuals as ordinary income. Trading costs and tax effects associated with frequent trading may adversely affect the Fund’s performance.

As a temporary defensive measure, the Fund may hold any portion of its assets in cash (U.S. Dollars, foreign currencies or multinational currency units) and/or invest in money market instruments or high quality debt securities as Vaughan Nelson deems appropriate. The Fund may miss certain investment opportunities if it uses such defensive strategies and thus may not achieve its investment goal.

Principal Investment Risks

Equity securities risk: You may lose money on your investment due to unpredictable drops in a stock’s value or periods of below-average performance in a given stock or in the stock market as a whole. The value of the Fund’s investments in equity securities is subject to the risks of unpredictable declines in the value of individual securities, industries and periods of below-average performance in individual securities, industries or in the equity market as a whole. Securities issued in IPOs tend to involve greater market risk than other equity securities due, in part, to public perception and the lack of publicly available information and trading history. Value stocks present the risk that their lower valuations fairly reflect their business prospects or that other investors will not agree that the stocks represent favorable investment opportunities, and they may fall out of favor with investors and underperform growth stocks during any given period. Equity securities may include common stocks, preferred stocks, warrants, securities convertible into common or preferred stocks and other equity-like interests in an entity. Common stocks represent an equity or ownership interest in an issuer. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s bonds and preferred stock take precedence over the claims of those who own common stock. Equity securities may take the form of stock in corporations, limited partnership interests, interests in limited liability companies, REITs or other trusts and other similar securities.

Management risk: The risk that a strategy used by the Fund’s portfolio managers may fail to produce the intended result.

GOALS, STRATEGIES & RISKS

subject to liabilities under environmental and hazardous waste laws. In addition, the value of a REIT is affected by changes in the value of the properties owned by the REIT or securing mortgage loans held by the REIT. REITs are dependent upon cash flow from their investments to repay financing costs and also on the ability of the REITs’ managers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Other expenses include expenses indirectly borne by the Fund through investments in certain pooled investment vehicles (“Acquired Fund Fees and Expenses”) of less than 0.01% of the Fund’s average daily net assets. The expense information shown in the table above may differ from the expense information disclosed in the Fund’s financial highlights table because the financial highlights table reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

^††	Fee reduction and/or expense reimbursement and Net Expenses have been restated to reflect the current expense cap arrangement.

^‡	Other expenses are estimated for the current fiscal year.

*	Because of the higher service and distribution (12b-1) fees, long-term shareholders may pay more than the economic equivalent of the maximum front-end sales charge permitted by the rules of Financial Industry Regulatory Authority (“FINRA”).

Except as otherwise noted, the information in the table is based on amounts incurred during the Fund’s most recent fiscal year. The Fund’s annual operating expenses will likely vary from year to year. It is important for you to understand that a decline in the Fund’s average net assets during current fiscal year due to recent market volatility or other factors could cause the Fund’s expense ratios for the Fund’s current fiscal year to be higher than the expense information presented.

More About Risk

Each Fund has principal investment strategies that come with inherent risks. The following is a list of non-principal risks to which each Fund may be subject because of its investments in various types of securities or engagement in various practices.

Correlation Risk (All Funds except AEW Real Estate and Delafield Select Funds)

The risk that changes in the value of a hedging instrument will not match those of the asset being hedged.

Credit Risk (All Funds)

The risk that the issuer or the guarantor of a fixed-income security, or the counterparty to a derivatives or other transaction, will be unable or unwilling to make timely payments of interest or principal or to otherwise honor its obligations. Lower-rated fixed-income securities are considered predominantly speculative with respect to the ability of the issuer to make timely principal and interest payments. Foreign securities may be subject to increased credit risk because of the potential difficulties of requiring foreign entities to honor their contractual commitments.

Currency Risk (All Funds except AEW Real Estate and Harris Associates Large Cap Value Funds)

The risk that fluctuations in the exchange rates between the U.S. dollar and foreign currencies may negatively affect an investment.

Emerging Markets Risk (Hansberger International, Natixis U.S. Diversified Portfolio, Vaughan Nelson Small Cap Value and Vaughan Nelson Value Opportunity Funds)

The risk associated with investing in companies traded in developing securities markets, which may be smaller and have shorter operating histories than companies in developed markets. Emerging markets involve risks in addition to and greater than those generally associated with investing in developed foreign markets. The extent of economic development, political stability, market depth, infrastructure and capitalization, and regulatory oversight in emerging market economies is generally less than in more developed markets. Settlement practices for transactions in foreign markets may differ from those in U.S. markets. Such differences include delays beyond periods customary in the United States and practices, such as delivery of securities prior to receipt of payment, which increase the likelihood of a “failed settlement.” Failed settlements can result in losses to the funds.

Extension Risk (AEW Real Estate, Natixis U.S. Diversified Portfolio, Vaughan Nelson Small Cap Value and Vaughan Nelson Value Opportunity Funds)

The risk that an unexpected rise in interest rates will extend the life of a mortgage- or asset-backed security beyond the expected prepayment time, typically reducing the security’s value.

Foreign Risk (All Funds)

The risk associated with investments in issuers located in foreign countries. A Fund’s investments in foreign securities may experience more rapid and extreme changes in value than investments in securities of U.S. companies. In the event of a nationalization, expropriation or other confiscation, a Fund that invests in foreign securities could lose its entire investment. When a Fund invests in securities from issuers located in countries with emerging markets, it may face greater foreign risk since emerging market countries may be more likely to experience political and economic instability. A Fund’s investment in foreign securities may be subject to foreign withholding and other taxes. In that case, the Fund’s yield on those securities would be decreased.

Information Risk (All Funds)

The risk that key information about a security is inaccurate or unavailable. Securities issued in initial public offerings, or IPO’s, involve greater information risk than other equity securities due to the lack of public information.

Interest Rate Risk (All Funds)

The risk of market losses attributable to changes in interest rates. In general, the prices of fixed-income securities rise when interest rates fall, and prices fall when interest rates rise.

Natixis Equity Funds

Prospectus – May 1, 2009

MORE ABOUT RISK

Leverage Risk (All Funds except AEW Real Estate Fund)

The risk associated with securities or practices (e.g., borrowing or derivatives) that multiply small index or market movements into larger changes in value. When a derivative security (a security whose value is based on another security, currency, index or other instrument) is used as a hedge against an offsetting position that a Fund also holds, any loss generated by the derivative security should be substantially offset by gains on the hedged instrument, and vice versa. To the extent that a Fund uses a derivative security for purposes other than as a hedge, or, if a Fund hedges imperfectly, a Fund is directly exposed to the risks of that derivative security and any loss generated by the derivative security will not be offset by a gain. Structured notes may be considered derivative securities and may be subject to this type of risk.

Liquidity Risk (All Funds)

Liquidity risk exists when particular investments are difficult to purchase or sell, possibly preventing the Fund from selling these illiquid securities at an advantageous price or at the time desired. A lack of liquidity may also cause the value of investments to decline. Derivatives and securities that involve substantial interest rate or credit risk tend to involve greater liquidity risk. In addition, liquidity risk tends to increase to the extent the Fund invests in securities whose sale may be restricted by law or by contract, such as Rule 144A securities. Investment in derivatives may be especially illiquid when compared to other securities, especially during periods of market stress. Similarly, at certain times, the market for money market and similar instruments may become illiquid. At these times, it may be difficult to sell securities. Illiquid investments may also be difficult to value.

Opportunity Risk (All Funds)

The risk of missing out on an investment opportunity because the assets necessary to take advantage of it are invested in less profitable investments.

Options, Futures, Swap Contracts and Other Derivatives Risks (All Funds, except AEW Real Estate Fund)

Certain of the Funds may use derivatives, which are financial contracts whose value depends upon or is derived from the value of an underlying asset, currency, reference rate or index. Derivatives include, among other things, options, futures, swaps (including credit default swaps) and structured notes. The Funds may (but are not required to) use derivatives as part of a strategy designed to reduce exposure to other risks, such as risks associated with changes in interest rates or currency risk (“hedging”). The Funds may also use derivatives for leverage, which increases opportunities for gain but also involves greater risk of loss due to leveraging risk, and to earn income, enhance yield or gain exposure to issuers, indices, sectors, currencies and/or geographic regions. The use of derivatives for these purposes entails greater risk than using derivatives solely for hedging purposes.

Funds that use derivatives also face additional risks, such as liquidity risk, market risk, management risk, the credit risk relating to the other party to a derivative contract, the risk of difficulties in pricing and valuation, the risk of ambiguous documentation and the risk that changes in the value of a derivative may not correlate perfectly with relevant assets, rates, or indices. This could, for example, cause a derivative transaction to imperfectly hedge the risk which it was intended to hedge. A Fund’s use of derivative instruments may involve risks greater than the risks associated with investing directly in securities and other traditional investments, may cause the Fund to lose more than the principal amount invested and may subject a Fund to the potential for unlimited loss. A Fund may be required to sell other securities at inopportune times to meet collateral requirements on its derivative transactions. In addition, a Fund’s use of derivatives may increase or accelerate the amount of taxes payable by shareholders. Also, suitable derivative transactions may not be available in all circumstances and there can be no assurance that a Fund will engage in these transactions to reduce exposure to other risks when that would be beneficial or that, if used, such strategies will be successful.

Political Risk (All Funds)

The risk of losses directly attributable to government or political actions.

Prepayment Risk (AEW Real Estate, Natixis U.S. Diversified Portfolio, Vaughan Nelson Small Cap Value and Vaughan Nelson Value Opportunity Funds)

The risk that unanticipated prepayments may occur, reducing the return from mortgage- or asset-backed securities or REITs.

Natixis Equity Funds

Prospectus – May 1, 2009

MORE ABOUT RISK

Small Capitalization Companies Risk (AEW Real Estate, Natixis U.S. Diversified Portfolio, Hansberger International and Vaughan Nelson Small Cap Value Funds)

These companies carry special risks, including narrower markets, more limited financial and management resources, less liquidity and greater volatility than large company securities.

Valuation Risk (All Funds)

The risk that the Fund has valued certain securities at a higher price than the price at which they can be sold. This risk may be especially pronounced for investments, such as derivatives, which may be illiquid or which may become illiquid.

Percentage Investment Limitations. Except as set forth in the Statement of Additional Information (“SAI”), the percentage limitations set forth in this Prospectus and the SAI apply at the time an investment is made and shall not be considered violated unless an excess or deficiency occurs or exists immediately after and as a result of such investment.

MANAGEMENT TEAM

A discussion of the factors considered by the Funds’ Board of Trustees in approving the Funds’ investment advisory and sub-advisory contracts is available in the Funds’ financial reports for the six months ended June 30, 2008 for the Hansberger International Fund, Harris Associates Large Cap Value Fund, Natixis U.S. Diversified Portfolio and Vaughan Nelson Small Cap Value Fund, for the six months ended July 31, 2008 for the AEW Real Estate Fund and for the twelve months ended December 31, 2008 for the Delafield Select Fund and the Vaughan Nelson Value Opportunity Fund.

Portfolio Trades

In placing portfolio trades, the Fund’s adviser or subadviser may use brokerage firms that market the Funds’ shares or are affiliated with Natixis US, Natixis Advisors or any adviser or subadviser. In placing trades, any adviser or subadviser will seek to obtain the best combination of price and execution, which involves a number of subjective factors. Such portfolio trades are subject to applicable regulatory restrictions and related procedures adopted by the Board of Trustees.

Securities Lending. Each Fund may lend a portion of its portfolio securities to brokers, dealers and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. Please see “Investment Strategies” in the SAI for details. When a Fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the Fund will also receive a fee or interest on the collateral. Securities lending involves the risk of loss of rights in the collateral or delay in recovery of the collateral if the borrower fails to return the security loaned or becomes insolvent. A Fund may pay lending fees to the party arranging the loan.

In addition, any investment of cash is generally at the sole risk of the Funds. Any income or gains and losses from investing and reinvesting any cash collateral delivered by a borrower pursuant to a loan are generally at the Funds’ risk, and to the extent any such losses reduce the amount of cash below the amount required to be returned to the borrower upon the termination of any loan, the Funds may be required by the securities lending agent to pay or cause to be paid to such borrower an amount equal to such shortfall in cash, possibly requiring it to liquidate other portfolio securities to satisfy its obligations.

Transactions with Other Investment Companies. Pursuant to SEC exemptive relief, each Fund may be permitted to invest its daily cash balances in shares of money market and short-term bond funds advised by Natixis Advisors or its affiliates (“Central Funds”). The Central Funds currently include two money market funds: the Money Market Fund and the Daily Income Fund. The Money Market Fund is advised by Natixis Advisors and subadvised by Reich & Tang and the Daily Income Fund is advised by Reich & Tang. Because Natixis Advisors and Reich & Tang are each subsidiaries of Natixis US, the Fund and the Central Funds may be considered to be related companies comprising a “group of investment companies” under the 1940 Act. The Funds may also make investments in related investment companies to the extent permitted by SEC regulation.

Pursuant to such exemptive relief, the Funds may also borrow and lend money for temporary or emergency purposes directly to and from other funds through an interfund credit facility. In addition to the Funds and the Central Funds, series of the following mutual fund groups may also be able to participate in the facility: Natixis Funds Trust I (except the CGM Advisor Targeted Equity Fund series), Natixis Funds Trust II, Natixis Funds Trust III, Natixis Funds Trust IV, Harris Associates Investment Trust, Loomis Sayles Funds I, Loomis Sayles Funds II and Gateway Trust. The advisers and subadvisers to these mutual funds currently include Natixis Advisors, Reich & Tang, Loomis Sayles, AEW, BlackRock, Gateway Investment Advisers, LLC, Harris Associates, Hansberger and Vaughan Nelson. Each of these advisers and subadvisers (except BlackRock) are subsidiaries of Natixis US and are thus “affiliated persons” under the 1940 Act by reason of being under common control by Natixis US. In addition, because the Funds, and other funds, are advised by firms that are affiliated with one another, they may be considered to be related companies comprising a “group of investment companies” under the 1940 Act. The Central Funds will participate in the credit facility only as lenders. Participation in such an interfund lending program would be voluntary for both borrowing and lending funds, and a Fund would participate in an interfund lending program only if the Board of Trustees determined that doing so would benefit the Fund. Should a Fund participate in such an interfund lending program, the Board of Trustees would establish procedures for the operation of the program by the advisers or an affiliate. The Funds may engage in the transactions described above without further notice to shareholders. The Funds may also make investments in related investment companies to the extent permitted by SEC regulation.

Investing in the Funds

Choosing a Share Class

Each Fund offers Class A and Class C shares to the public. No new accounts may be opened and no additional investments may be made in Class B shares. Each class has different costs associated with buying, selling and holding Fund shares, which allows you to choose the class that best meets your needs. Which class is best for you depends upon the size of your investment and how long you intend to hold your shares. Class C shares and certain shareholder features may not be available to you if you hold your shares in a street name account. Your financial representative can help you decide which class of shares is most appropriate for you.

Class A Shares

•

You pay a sales charge when you buy Class A shares. There are several ways to reduce this charge. See the section “How Sales Charges Are Calculated.”

•

You pay lower annual expenses than Class B and Class C shares, giving you the potential for higher returns per share. However, where front-end sales charges are applicable, returns are earned on a smaller amount of your investment.

•

You do not pay a sales charge on orders of $1 million or more, but you may pay a charge on redemptions if you redeem these shares within one year of purchase.

Class B Shares

•

No new accounts may be opened and no additional investments may be made in Class B shares.

•

Class B shares pay higher expenses than Class A shares.

•

You will pay a charge on redemptions if you sell your shares within six years of purchase, as described in the section “How Sales Charges Are Calculated.”

•

Your Class B shares will automatically convert into Class A shares after eight years, which reduces your annual expenses.

Class C Shares

•

You do not pay a sales charge when you buy Class C shares. All of your money goes to work for you right away.

FUND SERVICES

•

You pay higher annual expenses than Class A shares.

•

You may pay a sales charge on redemptions if you sell your shares within one year of purchase.

•

Your Class C shares will not automatically convert into Class A shares. If you hold your shares for longer than eight years, you will pay higher expenses than shareholders of other classes.

•

Investors will not be permitted to purchase $1 million or more of Class C shares as a single investment per account. There may be certain exceptions to this restriction for omnibus and other nominee accounts. Investors may want to consider the lower operating expense of Class A shares in such instances. You may pay a charge on redemptions if you redeem Class A shares within one year of purchase.

For information about the Fund’s expenses, see the section “Fund Fees & Expenses” in this Prospectus.

Certificates

Certificates will not be issued for any class of shares.

How Sales Charges are Calculated

Class A Shares

The price that you pay when you buy Class A shares (the “offering price”) is their net asset value plus a sales charge (sometimes called a “front-end sales charge”) which varies depending upon the size of your purchase:


	Class A Sales Charges**
Your Investment	As a % of offering price		As a % of your investment
Less than $ 50,000	5.75	%	6.10	%
$ 50,000 – $ 99,999	4.50	%	4.71	%
$ 100,000 – $249,999	3.50	%	3.63	%
$ 250,000 – $499,999	2.50	%	2.56	%
$ 500,000 – $999,999	2.00	%	2.04	%
$1,000,000 or more*	0.00	%	0.00	%

Due to rounding, the actual sales charge for a particular transaction may be higher or lower than the rates listed above.

*	For purchases of Class A shares of the Fund of $1 million or more, there is no front-end sales charge, but a CDSC of 1.00% may apply to redemptions of your shares within one year of the date of purchase. See the section “How the CDSC is Applied to Your Shares.”

**	Not imposed on shares that are purchased with reinvested dividends or other distributions.

If you invest in Class A shares through a financial intermediary, it is the responsibility of the financial intermediary to ensure that you obtain the proper “breakpoint” discount. It will be necessary at the time of purchase to inform the Distributor and the financial intermediary of the existence of other accounts in which there are holdings eligible to be aggregated to meet sales load breakpoints of the Fund. You may be required to provide certain records and information, such as account statements, with respect to all of your accounts which hold shares, including accounts with other financial intermediaries and your family members’ and other related party accounts, in order to verify your eligibility for a reduced sales charge. If the Distributor is not notified that you are eligible for a reduced sales charge, the Distributor will be unable to ensure that the reduction is applied to your account. Additional information concerning sales load breakpoints is available from your financial intermediary, by visiting the Fund’s website at www.funds.natixis.com (click on “sales charges” at the bottom of the home page) or in the Funds’ SAI.

Reducing Front-End Sales Charges

There are several ways you can lower your sales charge for Class A shares, including:

•

Letter of Intent — By signing a Letter of Intent, you may purchase Class A shares of any Natixis Fund over a 13-month period but pay sales charges as if you had purchased all shares at once. This program can save you money if you plan to invest $100,000 or more within 13 months. Purchases of Class C shares may be used toward meeting the letter of intent.

Natixis Equity Funds

Prospectus – May 1, 2009

FUND SERVICES

•

Cumulative Purchase Discount — You may be entitled to a reduced sales charge if your “total investment” reaches a breakpoint for a reduced sales charge. The total investment is determined by adding the amount of your current purchase in a Fund, including the applicable sales charge, to the current public offering price of all series and classes of shares of the Natixis Funds held by you in one or more accounts. If your total investment exceeds a sales charge breakpoint in the table above, the lower sales charge applies to the entire amount of your current purchase in a Fund.

•

Combining Accounts — This allows you to combine shares of multiple Natixis Funds and classes for purposes of calculating your sales charge.

Individual Accounts: You may elect to combine your purchase(s) and your total investment, as defined above, with the purchases and total investment of your spouse, parents, children, siblings, grandparents, grandchildren, in-laws (of those previously mentioned), individual fiduciary accounts, sole proprietorships, single trust estates and any other individuals acceptable to the Distributor.

Certain Retirement Plan Accounts: The Distributor may, in its discretion, combine the purchase(s) and total investment of all qualified participants in the same retirement plan for purposes of determining the availability of a reduced sales charge.

In most instances, individual accounts may not be linked with certain retirement plan accounts for the purposes of calculating sales charges. Savings Incentive Match Plan for Employees (“SIMPLE IRA”) contributions will automatically be linked with those of other participants in the same SIMPLE IRA Plan (Class A shares only). SIMPLE IRA accounts may not be linked with any other Natixis Fund account for rights of accumulation. Please refer to the SAI for more detailed information on combining accounts.

The above-listed ways to reduce front-end sales charges may not apply to the Money Market Fund unless shares are purchased through an exchange from another Natixis Fund.

Eliminating Front-End Sales Charges and CDSCs

Class A shares may be offered without front-end sales charges or a CDSC to the following individuals and institutions:

•

Any government entity that is prohibited from paying a sales charge or commission to purchase mutual fund shares;

•

Selling brokers, sales representatives, registered investment advisers, financial planners or other intermediaries under arrangements with the Distributor;

•

Fund trustees, former trustees, employees of affiliates of the Natixis Funds and other individuals who are affiliated with any Natixis Fund (including the Money Market Fund) (this also applies to any spouse, parents, children, siblings, grandparents, grandchildren and in-laws of those mentioned);

•

Participants in certain retirement plans with at least $1 million or more in total plan assets or with 100 eligible employees;

•

Non-discretionary and non-retirement accounts of bank trust departments or trust companies, but only if they principally engage in banking or trust activities;

•

Clients of an adviser or subadviser to any Natixis Fund (including the Money Market Fund) with investments of $25,000 or more in the Natixis Funds; and

•

Clients of Natixis Advisors that invest in a Natixis Fund that does not offer Class Y shares.

In order to receive Class A shares without a front-end sales charge or a CDSC, you must notify the Fund of your eligibility at the time of purchase.

Repurchasing Fund Shares

You may apply proceeds from redeeming Class A shares of a Fund to repurchase Class A shares of any Natixis Fund without paying a front-end sales charge. To qualify, you must reinvest some or all of the proceeds within 120 days after your redemption and notify Natixis Funds in writing (directly or through your financial representative) at the time of reinvestment that you are taking advantage of this privilege. You may reinvest your proceeds by sending a new check for some or all of the redemption amount. Please note: for federal income tax purposes, a redemption is a sale that involves tax consequences, even if the proceeds are later reinvested. Please consult your tax adviser to discuss how a redemption would affect you.

If you repurchase Class A shares of $1 million or more within 30 days after you redeem such shares, the Distributor will rebate the amount of the CDSC charged on the redemption if the Fund is notified in writing at the time of the repurchase.

Natixis Equity Funds

Prospectus – May 1, 2009

FUND SERVICES

Eliminating the CDSC

As long as the Distributor is notified at the time you sell, the CDSC for Class A shares will generally be eliminated in the following cases: (1) to make distributions from a retirement plan (a plan termination or total plan redemption may incur a CDSC); (2) to make payments through a systematic withdrawal plan; or (3) due to shareholder death or disability.

Please see the SAI for more information on eliminating or reducing front-end sales charges and CDSC.

Class B Shares

No new accounts may be opened and no additional investments may be made in Class B shares. There is a CDSC on shares that are sold within six years of the date of their acquisition. The amount of the CDSC, if any, declines each year that you own your shares (except in the 3rd and 4th years, which have the same CDSC). The holding period for purposes of timing the conversion to Class A shares and determining the CDSC will continue to run after an exchange to Class B shares of another Natixis Fund (except the Money Market Fund). The CDSC equals the following percentages of the dollar amounts subject to the charge:


Class B Contingent Deferred Sales Charges Year Since Purchase	CDSC on Shares Being Sold
1st	5.00	%
2nd	4.00	%
3rd	3.00	%
4th	3.00	%
5th	2.00	%
6th	1.00	%

As long as the Distributor is notified at the time you sell, the CDSC for Class B shares will generally be eliminated in the following cases: (1) to make distributions from a retirement plan (a plan termination or total plan redemption may incur a CDSC); (2) to make payments through a systematic withdrawal plan; or (3) due to shareholder death or disability.

Please see the SAI for more information on eliminating or reducing front-end sales charges and CDSC.

Class C Shares

The offering price of Class C shares is their net asset value, without a front-end sales charge. Class C shares are subject to a CDSC of 1.00% on redemptions made within one year of the date of their acquisition. The holding period for determining the CDSC will continue to run after an exchange to Class C shares of another Natixis Fund (except the Money Market Fund).

Please see the SAI for more information on eliminating or reducing front-end sales charges and the CDSC.

How the CDSC is Applied to Your Shares

The CDSC is a sales charge you pay when you redeem certain Fund shares. The CDSC:

•

is calculated based on the number of shares you are selling;

Natixis Equity Funds

Prospectus – May 1, 2009

FUND SERVICES

•

is based on either your original purchase price or the current net asset value of the shares being sold, whichever is lower;

•

is deducted from the proceeds of the redemption unless you request, at the time of the redemption, that it be deducted from the amount remaining in your account; and

•

applies to redemptions made through the date of their acquisition for years one through six, as applicable.

A CDSC will not be charged on:

•

increases in net asset value above the purchase price; or

•

shares you acquired by reinvesting your dividends or capital gains distributions.

To keep your CDSC as low as possible, each time that you place a request to sell shares we will first sell any shares in your account that carry no CDSC. If there are not enough of these shares available to meet your request, we will sell the shares with the lowest CDSC.

Exchanges into Shares of the Money Market Fund

If you exchange Class B or Class C shares of a Fund into shares of the Money Market Fund, the holding period for purposes of determining the CDSC for Class B and Class C shares and conversion into Class A shares from Class B stops until you exchange back into shares of another Natixis Fund. If you choose to redeem those Money Market Fund shares, a CDSC may apply.

Compensation to Securities Dealers

As part of their business strategies, the Funds pay securities dealers and other financial institutions (collectively, “dealers”) that sell their shares. This compensation originates from two sources: sales charges (front-end or deferred) and 12b-1 fees (comprising the annual service and/or distribution fees paid under a plan adopted pursuant to Rule 12b-1 under the 1940 Act). The sales charges, some or all of which may be paid to dealers, are discussed in the section “How Sales Charges Are Calculated” and dealer commissions as a percentage of offering price is disclosed in the Funds’ SAI. Each class of Fund shares offered in this prospectus pays an annual service fee of 0.25% of its average daily net assets. In addition to a service fee, each Fund’s Class B shares pay an annual distribution fee of 0.75% of their average daily net assets for 8 years (at which time they automatically convert into Class A shares). Class C shares are subject to an annual distribution fee of 0.75% of their average daily net assets. Generally, the 12b-1 fees are paid to securities dealers on a quarterly basis, but may be paid on other schedules. The Distributor retains the first year of such fees for Class B and Class C shares. Some or all of such fees may also be paid to financial institutions that finance the payment of commissions or similar charges on Class B shares. Because these distribution fees and service fees are paid out of the Funds’ assets on an ongoing basis, over time these fees for Class B and Class C shares will increase the cost of your investment and may cost you more than paying the front-end sales charge and service fees on Class A shares.

The Distributor, the Funds’ adviser and each of their respective affiliates may, out of their own resources, which generally come directly or indirectly from fees paid by the Funds, make payments to certain dealers and other financial intermediaries that satisfy certain criteria established from time to time by the Distributor. Payments may vary based on sales, the amount of assets a dealer’s or intermediary’s clients have invested in the Funds, and other factors. These payments may also take the form of sponsorship of seminars or informational meetings or payments for attendance by persons associated with a dealer or intermediary at informational meetings. The Distributor and its affiliates may also make payments for recordkeeping and other transfer agency-related services to dealers and intermediaries that sell Fund shares.

The payments described in this section, which may be significant to the dealers and the financial intermediaries, may create an incentive for a dealer or financial intermediary or their representatives to recommend or sell shares of a particular fund or share class over other mutual funds or share classes. Additionally, these payments may result in the Funds’ receiving certain marketing or servicing advantages that are not generally available to mutual funds that do not make such payments, including placement on a sales list, including a preferred or select sales list, or in other sales programs. These payments may create potential conflicts of interest between an investor and a dealer or other financial intermediary who is recommending a particular mutual fund over other mutual funds. Before investing, you should consult with your financial representative and review carefully any disclosure by the dealer or other financial intermediary as to what monies it

receives from mutual fund advisers and distributors, as well as how your financial representative is compensated. Please see the SAI for additional information about payments made by the Distributor and its affiliates to dealers and intermediaries. Please also contact your dealer or financial intermediary for details about payments it may receive.

SARSEP plans established prior to January 1, 1997, are subject to the same minimums as SIMPLE IRAs. As of October 1, 2006, Natixis Funds no longer offers SIMPLE IRAs. SIMPLE IRA plans established prior to October 1, 2006 may remain active and continue to add new employees, however SIMPLE IRA plans are not offered in Funds established after October 1, 2006.

The Distributor, in its sole discretion, may lower investment minimums for accounts associated with wrap-fee programs sponsored by certain broker-dealers and investment advisers and for accounts associated with certain other defined contribution plans not using the Natixis Funds’ prototype document.

The Distributor, at its sole discretion, may waive the minimum investment for new accounts being established into existing Corporate Retirement Plans and existing SEP-IRA, SARSEP and Keogh Plans using the Natixis Funds’ prototype document.

The Funds are not available to new Savings Incentive Match Plan for Employees (“SIMPLE IRAs”).

Complete the appropriate parts of the account application, carefully following the instructions. If you have any questions, please call your financial representative or Natixis Funds at 800-225-5478.

4.	Use the sections of this Prospectus that follow as your guide for purchasing shares.

Minimum Balance Policy

Each Fund, on an annual basis, may deduct a minimum balance fee of $20 for accounts that fall below the minimum amount required to establish an account, as described above. The minimum balance fee is assessed by the automatic redemption of shares in the account in an amount sufficient to pay the fee. The valuation of account balances for this purpose and the deduction of the fee generally occur during September of each calendar year, although they may occur at another date in the year. The fee will not be deducted from Fund positions opened after June 30th of the calendar year in which the fee is assessed. Certain accounts, such as Class B accounts, accounts that fall below the minimum as a result of the automatic conversion from Class B to Class A shares, accounts using the Natixis Funds’ prototype document (including IRAs, Keogh plans, 403(b)(7) plans and Coverdell Education Savings Accounts) and accounts associated with defined contribution plans, are excepted from the minimum balance fee.

Natixis Equity Funds

Prospectus – May 1, 2009

FUND SERVICES

In its discretion, the Fund may also close an account and send the account holder the proceeds if the account falls below the minimum amount required to establish an account. The valuation of account balances for this purpose and the liquidation itself generally occur during October of each calendar year, although they may occur at another date in the year. Any account opened after June 30th of a calendar year will not be subject to the liquidation for that calendar year. Certain accounts, such as Class B accounts, accounts associated with wrap-fee programs or defined contribution plans, are excepted from the liquidation. The determination of whether to deduct the minimum balance fee or close an account is made at the discretion of the Funds.

It is expected that accounts maintained by intermediaries through the National Securities Clearing Corporation may be liquidated rather than assessed a fee if the account balance falls below such minimum, and that directly registered accounts may be assessed a fee rather than liquidated.

Selling Shares in Writing

If you wish to redeem your shares in writing, all owners of the shares must sign the redemption request in the exact names in which the shares are registered and indicate any special capacity in which they are signing. In certain situations, you will be required to make your request to sell shares in writing. In these instances, a letter of instruction signed by the authorized owner is necessary. In certain situations, we also may require a medallion signature guarantee or additional documentation.

A medallion signature guarantee protects you against fraudulent orders and is necessary if:

•

your address of record or bank account information has been changed within the past 30 days;

•

you are selling more than $100,000 worth of shares and you are requesting the proceeds by check;

•

a proceeds check for any amount is either mailed to an address other than the address of record or not payable to the registered owner(s); or

•

the proceeds are sent by check, wire, or in some circumstances ACH to a bank account whose owner(s) do not match the owner(s) of the fund account.

A notary public cannot provide a medallion signature guarantee. The Funds will only accept medallion signature guarantees bearing the STAMP2000 Medallion imprint. A medallion signature guarantee can be obtained from one of the following sources:

•

a financial representative or securities dealer;

•

a federal savings bank, cooperative, or other type of bank;

•

a savings and loan or other thrift institution;

•

a credit union; or

•

a securities exchange or clearing agency.

In some situations additional documentation may be necessary. Please contact your financial representative or Natixis Funds regarding documentation requirements.

Exchanging Shares

In general, you may exchange shares of your Fund for shares of the same class of another Natixis Fund or Loomis Sayles Fund that offers such class of shares, without paying a sales charge or a CDSC (see the sections “Buying Shares” and “Selling Shares”) subject to certain restrictions noted below. For exchanges into the Money Market Fund, the holding period for determining the CDSC and conversion into Class A shares, if applicable, for Class B and Class C Shares will stop and will resume only when an exchange into an applicable fund occurs. The exchange must be for at least the minimum to open an account (or the total net asset value of your account, whichever is less), or, once the fund minimum is met, exchanges under the Automatic Exchange Plan must be made for at least $100 (see the section “Additional Investor Services”). All exchanges are subject to the eligibility requirements of the fund into which you are exchanging and any other limits on sales of or exchanges into that fund. The exchange privilege may be exercised only in those states where shares of such funds may be legally sold. For federal income tax purposes, an exchange of fund shares for shares of another fund is generally treated as a sale on which gain or loss may be recognized. Subject to the applicable rules of the SEC, the Board of Trustees reserves the right to modify the exchange privilege at any time. Before requesting an exchange into any other fund, please read its prospectus carefully. You may be unable to hold your shares through the same financial intermediary if you engage in certain share exchanges. You should contact your financial intermediary for further details. Please refer to the SAI for more detailed information on exchanging Fund shares.

Accounts participating in wrap fee programs or held through a Registered Investment Adviser may exchange Class A shares of a fund for Class Y shares of the same fund. In order to exchange shares, a representative of the wrap fee program or Registered Investment Adviser must follow the procedures set forth by the Distributor. An exchange of shares for shares of a different class in the same fund generally should not be a taxable event for the exchanging shareholder.

Due to operational limitations at your financial intermediary your ability to exchange Class A shares of a fund for Class Y shares of the same fund may be limited. Please consult your financial representative for more information.

Restrictions on Buying, Selling and Exchanging Shares

The Funds discourages excessive, short-term trading that may be detrimental to the Funds and their shareholders. Frequent purchases and redemptions of Fund shares by shareholders may present certain risks for other shareholders in a Fund. This includes the risk of diluting the value of Fund shares held by long-term shareholders, interfering with the efficient management of the Fund’s portfolio, and increasing brokerage and administrative costs. Funds investing in securities that require special valuation processes (such as foreign securities, high yield securities, or small cap securities) may also have increased exposure to these risks. The Board of Trustees has adopted the following policies to address and discourage such trading.

Each Fund reserves the right to suspend or change the terms of purchasing or exchanging shares. Each Fund and the Distributor reserve the right to reject any purchase or exchange order for any reason, including if the transaction is deemed not to be in the best interests of the Fund’s other shareholders or possibly disruptive to the management of the Fund. A shareholder whose exchange order has been rejected may still redeem its shares by submitting a redemption request as described above under “Selling Shares.”

Limits on Frequent Trading. Without limiting the right of each Fund and the Distributor to reject any purchase or exchange order, each Fund and the Distributor may (but are not obligated to) restrict purchases and exchanges for the accounts of “market timers.” An account may be deemed to be one of a market timer if it makes two “round trips” in any Fund over a 90-day interval, as determined by the Fund. A “round trip” is a purchase (including a purchase by exchange) into a Fund followed by a redemption (including a redemption by exchange) of any amount out of the same Fund. The above limits are applicable whether you hold shares directly with a Fund or indirectly through a financial intermediary, such as a broker, bank, investment adviser, recordkeeper for retirement plan participants, or other third party. The preceding is not an exclusive description of activities that the Funds and the Distributor may consider to be “market timing.”

Notwithstanding the above, certain financial intermediaries, such as retirement plan administrators, may monitor and restrict the frequency of purchase and redemption transactions in a manner different from that described above. The policies of these intermediaries may be more or less restrictive than the generally applicable policies described above. Each Fund may choose to rely on a financial intermediary’s restrictions on frequent trading in place of the Fund’s own restrictions if the Fund determines, in its discretion, that the financial intermediary’s restrictions provide reasonable protection for the Fund from excessive short-term trading activity. Please contact your financial representative for additional information regarding their policies for limiting the frequent trading of Fund shares.

This policy also does not apply with respect to shares purchased by certain funds-of-funds or similar asset allocation programs that rebalance their investments only infrequently. To be eligible for this exemption, the fund-of-funds or asset allocation program must identify itself to and receive prior written approval from the Fund or the Distributor. A Fund and Distributor may request additional information to enable them to determine that the fund-of-funds or asset allocation program is not designed to and/or is not serving as a vehicle for disruptive short-term trading, which may include requests for (i) written assurances from the sponsor or investment manager of the fund-of-funds or asset allocation program that it enforces the Fund’s frequent trading policy on investors or another policy reasonably designed to deter disruptive short-term trading in Fund shares, and/or (ii) data regarding transactions by investors in the fund-of-funds or asset allocation program, for periods and on a frequency determined by the Fund and Distributor, so that the Fund can monitor compliance by such investors with the trading limitations of the Fund or of the fund-of-funds or asset allocation program.

Trade Activity Monitoring. Trading activity is monitored selectively on a daily basis in an effort to detect excessive short-term trading activities. If the Fund or the Distributor believes that a shareholder or financial intermediary has engaged in market timing or other excessive, short-term trading activity, it may, in its discretion, request that the shareholder or financial intermediary stop such activities or refuse to process purchases or exchanges in the accounts. In its discretion, the Fund or the Distributor may restrict or prohibit transactions by such identified shareholders or intermediaries. In making such judgments, the Fund and the Distributor seek to act in a manner that they believe is consistent with the best interests of all shareholders. The Fund and the Distributor also reserve the right to notify financial intermediaries of the shareholder’s trading activity.

Accounts Held by Financial Intermediaries. The ability of a Fund and the Distributor to monitor trades that are placed by omnibus or other nominee accounts is more limited in those instances in which the financial intermediary maintains the record of a Fund’s underlying beneficial owners. In general, each Fund and the Distributor will review trading activity at the

Natixis Equity Funds

Prospectus – May 1, 2009

FUND SERVICES

omnibus account level. If a Fund and the Distributor detect suspicious activity, they may request and receive personal identifying information and transaction histories for some or all underlying shareholders (including plan participants) to determine whether such shareholders have engaged in market timing or other excessive, short-term trading activity. If a Fund believes that a shareholder has engaged in market timing or other excessive, short-term trading activity in violation of the Fund’s policies through an omnibus account, the Fund will attempt to limit transactions by the underlying shareholder which engaged in such trading, although it may be unable to do so. The Fund may also limit or prohibit additional purchases of Fund shares by an intermediary. Investors should not assume the Fund will be able to detect or prevent all market timing or other trading practices that may disadvantage the Fund.

Purchase Restrictions

Each Fund is required by federal regulations to obtain certain personal information from you and to use that information to verify your identity. The Funds may not be able to open your account if the requested information is not provided. Each Fund reserves the right to refuse to open an account, close an account and redeem your shares at the then current price or take other such steps that the Fund deems necessary to comply with federal regulations if your identity cannot be verified.

Selling Restrictions

The table below describes restrictions placed on selling shares of the Fund. Please see the SAI for additional information regarding redemption payment policies:


Restriction		Situation

Each Fund may suspend the right of redemption or postpone payment for more than 7 days:		• When the New York Stock Exchange (the “NYSE”) is closed (other than a weekend/holiday) as permitted by the SEC. • During an emergency as permitted by the SEC. • During any other period permitted by the SEC.

Each Fund reserves the right to suspend account services or refuse transaction requests:		• With a notice of a dispute between registered owners or death of a registered owner. • With suspicion/evidence of a fraudulent act.

Each Fund may pay the redemption price in whole or in part by a distribution in kind of readily marketable securities in lieu of cash or may take up to 7 days to pay a redemption request in order to raise capital:		• When it is detrimental for a Fund to make cash payments as determined in the sole discretion of the adviser or subadviser.

Each Fund may withhold redemption proceeds for 10 days from the purchase date:		• When redemptions are made within 10 calendar days of purchase by check or ACH to allow the check or ACH transaction to clear.

If you hold certificates representing your shares, they must be sent with your request for it to be honored. It is recommended that certificates be sent by registered mail.

Although most redemptions are made in cash, as described in the SAI, each Fund reserves the right to redeem shares in kind. If a shareholder receives a distribution in kind, the shareholder will bear the market risk associated with the distributed securities and may incur brokerage or other charges in converting the securities to cash.

How Fund Shares Are Priced

“Net asset value” is the price of one share of a Fund without a sales charge, and is calculated each business day using this formula:


Net Asset Value =		Total market value of securities + Cash and other assets – Liabilities
Net Asset Value =		Number of outstanding shares

The net asset value of Fund shares is determined pursuant to policies and procedures approved by the Board of Trustees, as summarized below:

•

A share’s net asset value is determined at the close of regular trading on the NYSE on the days the NYSE is open for trading. This is normally 4:00 p.m., Eastern time. The Fund’s shares will not be priced on the days on which the NYSE is closed for trading. In addition, the Fund’s shares will not be priced on the holidays listed in the SAI. See the section “Net Asset Value” in the SAI for more details.

•

The price you pay for purchasing, redeeming or exchanging a share will be based upon the net asset value next calculated (plus or minus applicable sales charges as described earlier in this Prospectus) after your order is received by the transfer agent “in good order.”¹

•

Requests received by the Funds after the NYSE closes will be processed based upon the net asset value determined at the close of regular trading on the next day that the NYSE is open. If the transfer agent receives the order in good order by 4:00 p.m., Eastern time, the shareholder will receive that day’s net asset value. Under limited circumstances, the Distributor may enter into contractual agreements pursuant to which orders received by your investment dealer before the Fund determines its net asset value (normally 4:00 p.m., Eastern time) are processed at the net asset value determined on the day the order was received by your investment dealer. Please contact your investment dealer to determine whether it has entered into such a contractual agreement. If your investment dealer has not entered into such a contractual agreement, your order will be processed at the net asset value next determined after your investment dealer submits the order to the Fund.

•

A fund that invests in foreign securities may have net asset value changes on days when you cannot buy or sell its shares.

1	Please see the section “Buying Shares”, which provides additional information regarding who can receive a purchase order.

Generally, during times of substantial economic or market change, it may be difficult to place your order by phone. During these times, you may deliver your order in person to the Distributor or send your order by mail as described in the sections “Buying Shares” and “Selling Shares.”

Generally, Fund securities are valued as follows:

•

Equity securities — last sale price on the exchange or market where primarily traded or, if there is no reported sale during the day, the closing bid price.

•

Debt securities (other than short-term obligations) — based upon evaluated prices furnished to a Fund by an independent pricing service, which service determines valuations for normal, institutional-size trading units of such securities using market information, transactions for comparable securities and various relationships between securities which are generally recognized by institutional traders.

•

Short-term obligations (purchased with an original or remaining maturity of 60 days or less) — amortized cost (which approximates market value).

•

Securities traded on foreign exchanges — market price on the foreign exchange, unless the Fund believes that an occurrence after the close of that exchange will materially affect the security’s value. In that case, the security may be fair valued at the time the Fund determines its net asset value by or pursuant to procedures approved by the Board of Trustees. When fair valuing their securities, the Funds may, among other things, use modeling tools or other processes that may take into account factors such as securities market activity and/or significant events that occur after the close of the local market and before the time a Fund’s net asset value is calculated.

•

Options — domestic exchange-traded single equity option contracts are valued at the mean of the National Best Bid and Offer quotations. Exchange-traded index options and foreign exchange-traded single equity options are valued at the average of the closing bid and asked quotations.

•

Futures — current settlement price.

•

Forward foreign currency contracts — interpolated prices determined based on information provided by an independent pricing service.

•

All other securities — fair market value as determined by the adviser or subadviser of the Fund pursuant to procedures approved by the Board of Trustees.

As described above, if market prices are not readily available for a security, securities may not be priced on the basis of quotations from the primary market in which they are traded but rather may be priced by another method that the Board of Trustees believes is more likely to result in a price that reflects fair value (which is the amount that a Fund might reasonably expect to receive from a current sale of the security in the ordinary course of business). The Fund may also value securities at fair value or estimate their value pursuant to procedures approved by the Board of Trustees in other circumstances such as when extraordinary events occur after the close of the relevant market but prior to the close of the NYSE. This may include situations relating to a single issuer (such as a declaration of bankruptcy or a delisting of the issuer’s security from the primary market on which it has traded) as well as events affecting the securities markets in general (such as market disruptions or closings and significant fluctuations in U.S. and/or foreign markets). Fair value pricing may require subjective determinations about the value of a security, and fair values used to determine the Fund’s net asset value may differ from quoted or published prices, or from prices that are used by others, for the same securities. In addition, the use of fair value pricing may not always result in adjustments to the prices of securities held by the Fund.

Dividends and Distributions

The Funds generally distribute most or all of their net investment income (other than capital gains) in the form of dividends. The following table shows when each Fund expects to distribute dividends. Each Fund expects to distribute all or substantially all of its net realized long- and short-term capital gains annually, after applying any available capital loss carryovers. To the extent permitted by law, the Board of Trustees may adopt a different schedule for making distributions as long as payments are made at least annually.


Dividend Payment Schedule
Annually		Quarterly
Delafield Select Fund		AEW Real Estate Fund
Hansberger International Fund
Harris Associates Large Cap Value Fund
Natixis U.S. Diversified Portfolio
Vaughan Nelson Small Cap Value Fund
Vaughan Nelson Value Opportunity Fund

Distributions will automatically be reinvested in shares of the same class of the distributing Fund at net asset value, unless you select one of the following alternatives:

•

Participate in the Dividend Diversification Program, which allows you to have all dividends and distributions automatically invested at net asset value in shares of the same class of another Natixis Fund registered in your name. Certain investment minimums and restrictions may apply. For more information about this program, see the section “Additional Investor Services.”

•

Receive distributions from dividends and interest in cash while reinvesting distributions from capital gains in additional shares of the same class of the Fund, or in the same class of another Natixis Fund; or

•

Receive all distributions in cash.

For more information or to change your distribution option, contact Natixis Funds in writing or call 800-225-5478.

If you earn more than $10 annually in taxable income from a Natixis Fund held in a non-retirement plan account, you will receive a Form 1099 to help you report the prior calendar year’s distributions on your federal income tax return. This information will also be reported to the Internal Revenue Service. Be sure to keep this Form 1099 as a permanent record. A fee may be charged for any duplicate information requested.

Tax Consequences

Except where noted, the discussion below addresses only the U.S. federal income tax consequences of an investment in a Fund and does not address any foreign, state or local tax consequences.

Each Fund intends to meet all requirements under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), necessary to qualify each year for treatment as a “regulated investment company,” and thus does not expect to pay any federal income tax on income and capital gains that are timely distributed to shareholders. Even though the Delafield Select Fund is not diversified for purposes of the 1940 Act, the Fund still intends to be diversified for purposes of meeting the requirements of Subchapter M.

Taxation of Distributions from the Funds. For federal income tax purposes, distributions of investment income generally are taxable to Fund shareholders as ordinary income. Taxes on distributions of capital gains are determined by how long a Fund owned the investments that generated them, rather than how long a shareholder has owned his or her shares. Distributions attributable to the excess of net long-term capital gains from the sale of investments a Fund owned for more than one year over net short-term capital losses and that are properly designated by the Fund as capital gain dividends (“Capital Gain Dividends”) will generally be taxable to a shareholder receiving such distributions as long-term capital gain. Distributions attributable to the excess of net short-term capital gains from the sale of investments that a Fund owned for one year or less over net long-term capital losses will be taxable as ordinary income.

For taxable years beginning before January 1, 2011, distributions of investment income designated by a Fund as derived from “qualified dividend income” will be taxed in the hands of individuals at the rates applicable to long-term capital gain, provided holding period and other requirements are met at both the shareholder and Fund levels. Income generated by investments in fixed income securities, derivatives and REITs generally is not eligible for treatment as qualified dividend income.

For taxable years beginning before January 1, 2011, long-term capital gain rates applicable to individuals have been temporarily reduced, in general to 15%, with lower rates applying to taxpayers in the 10% and 15% rate brackets.

Dividends and distributions declared by a Fund in October, November or December of one year and paid in January of the next year generally are taxable in the year in which the distributions are declared, rather than the year in which the distributions are received.

Fund distributions are taxable to shareholders even if they are paid from income or gains earned by a Fund before a shareholder’s investment (and thus were included in the price the shareholder paid for his or her shares). Such distributions are likely to occur in respect of shares purchased at a time when the relevant Fund’s net asset value reflects gains that are either unrealized or realized but not distributed. Fund distributions are taxable whether shareholders receive them in cash or in additional shares. Distributions by a Fund to retirement plans that qualify for tax-exempt treatment under federal income tax laws generally will not be taxable.

Redemption, Sale or Exchange of Fund Shares. A redemption, sale or exchange of Fund shares (including an exchange of Fund shares for shares of another Natixis Fund or Loomis Sayles Fund) is a taxable event and will generally result in recognition of gain or loss. Gain or loss, if any, recognized by a shareholder on a redemption, sale, exchange or other disposition of Fund shares generally will be taxed as long-term capital gain or loss if the shares are capital assets in the shareholder’s hands and the shareholder held the shares for more than one year.

Taxation of Certain Fund Investments. A Fund’s investments in foreign securities may be subject to foreign withholding and other taxes. In that case, the Fund’s yield on those securities would be decreased. Shareholders generally will not be entitled to claim a credit or deduction with respect to foreign taxes incurred by a Fund, except that a Fund investing more than 50 percent of its assets in foreign securities, such as the Hansberger International Fund, may elect to permit shareholders to claim a credit or deduction for their respective pro rata shares of qualifying foreign taxes paid by or withheld from amounts paid to the Fund. In such a case, shareholders will be required to include as gross income from foreign sources their pro rata shares of such taxes, and each shareholder’s ability to claim a foreign tax credit or deduction for such foreign taxes will be subject to generally applicable limitations imposed by the Code, which may result in a shareholder not getting a full credit or deduction for the amount of such taxes.

FUND SERVICES

In addition, a Fund’s investments in foreign securities and foreign currencies may be subject to special tax rules that have the effect of increasing or accelerating the Fund’s recognition of ordinary income and may affect the timing or amount of the Fund’s distributions.

A Fund’s investments in certain debt obligations, derivatives or REITs may cause the Fund to recognize taxable income in excess of the cash generated by such instruments. Thus, a Fund could be required to liquidate investments, including at times when it is not advantageous to do so, in order to satisfy its distribution requirements. In addition, a Fund’s investments in other investment companies could affect the amount, timing, and character of distributions from the Fund, and, therefore, may increase the amount of taxes payable by shareholders.

Backup Withholding. Each Fund is required in certain circumstances to apply backup withholding on taxable dividends, redemption proceeds and certain other payments that are paid to any shareholder if the shareholder does not furnish the Fund certain information and certifications or the shareholder is otherwise subject to backup withholding. The backup withholding tax rate is 28% for amounts paid on or before December 31, 2010 and will be 31% for amounts paid after December 31, 2010.

Please see the SAI for additional information on the federal income tax consequences of an investment in a Fund.

You should consult your tax adviser for more information on your own situation, including possible federal, state, local, foreign or other applicable taxes.

Dividend Diversification Program

This program allows you to have all dividends and any other distributions automatically invested in shares of the same class of another Natixis Fund or the Money Market Fund, subject to the eligibility requirements of that other fund and to state securities law requirements. Shares will be purchased at the selected fund’s net asset value without a front-end sales charge or CDSC on the dividend record date.

Automatic Exchange Plan

Natixis Funds have an automatic exchange plan under which shares of a class of a Natixis Fund are automatically exchanged each month for shares of the same class of another Natixis Fund or the Money Market Fund.

Please see the section “Exchanging Shares” above and refer to the SAI for more information on the Automatic Exchange Plan.

Systematic Withdrawal Plan

This plan allows you to redeem shares and receive payments from your Fund on a regular schedule. Redemptions of shares that are part of the Systematic Withdrawal Plan are not subject to a CDSC. However, the amount or percentage you specify in the plan may not exceed, on an annualized basis, 10% of the value of your Fund account based upon the value of your fund account on the day you establish your plan. For information on establishing a Systematic Withdrawal Plan, please refer to the section “Selling Shares.”

Glossary of Terms

American Depositary Receipts (ADRs) — Instruments issued by U.S. banks that represent an interest in equity securities held by arrangement with the bank. These instruments can be either “sponsored” or “unsponsored.” Sponsored depositary receipts are issued by banks in cooperation with the issuer of the underlying equity securities. Unsponsored depositary receipts are arranged without involvement by the issuer of the underlying equity securities.

Bid price — The price a prospective buyer is ready to pay. This term is used by traders who maintain firm bid and offer prices in a given security by standing ready to buy or sell security units at publicly quoted prices.

Bottom-up analysis — The analysis of potential performance of individual stocks before considering the impact of economic trends. Such companies may be identified from research reports, stock screens or personal knowledge of the products and services.

Capital gain distributions — Payments to a fund’s shareholders of net profits earned from selling securities in a fund’s portfolio. Capital gain distributions are usually paid once a year.

Credit rating — Independent evaluation of a bond’s creditworthiness. This measurement is usually calculated through an index compiled by companies such as Standard & Poor’s Ratings Group, Inc. (“S&P”), Moody’s Investors Service, Inc. (“Moody’s”), or Fitch Investors Services, Inc. (“Fitch”). Bonds with a credit rating of BBB or higher by S&P or Fitch, or Baa or higher by Moody’s, are generally considered investment-grade.

Debt-to-Total Capital Ratio — Total debt (current and long-term) divided by total capital (debt and equity). This ratio provides information regarding the extent of a company’s reliance on debt financing. A high ratio indicates a high degree of financial leverage and a high degree of risk.

Derivative — A financial instrument whose value and performance are based on the value and performance of another security or financial instrument.

Discounted price — The difference between a bond’s current market price and its face or redemption value.

Diversification — The strategy of investing in a wide range of securities representing different market sectors to reduce the risk if an individual company or one sector suffers losses.

Dividend yield — The current or estimated annual dividend divided by the market price per share of a security. Duration — An estimate of how much a bond’s price fluctuates with changes in comparable interest rates.

Earnings growth — A pattern of increasing rates of growth in earnings per share from one period to another, which usually causes a stock’s price to rise.

European Depositary Receipts (EDRs) — Instruments issued by European banks that represent an interest in equity securities held by arrangement with the bank. Sponsored depositary receipts are issued by banks in cooperation with the issuer of the underlying equity securities. Unsponsored depositary receipts are arranged without involvement by the issuer of the underlying equity securities.

FFO Multiple — The price per share of a REIT divided by its Funds from Operations (FFO). The FFO of a REIT is the measure of its operating performance showing its net income plus depreciation of real estate and excluding gains or losses from sales of property or debt restructuring.

Fundamental analysis — An analysis of the balance sheet and income statements of a company in order to forecast its future stock price movements. Fundamental analysis considers records of assets, earnings, sales, products, management and markets in predicting future trends in these indicators of a company’s success or failure. By appraising a company’s prospects, analysts using such an approach assess whether a particular stock or group of stocks is undervalued or overvalued at its current market price.

Global Depositary Receipts (GDRs) — Instruments issued by companies and offered in many markets around the world that represent an interest in equity securities held by arrangement with the bank. Sponsored depositary receipts are issued by banks in cooperation with the issuer of the underlying equity securities. Unsponsored depositary receipts are arranged without involvement by the issuer of the underlying equity securities.

GLOSSARY OF TERMS

Growth investing — An investment style that emphasizes companies with strong earnings growth. Growth investing is generally considered more aggressive than “value” investing.

Income distributions — Payments to a fund’s shareholders resulting from the net interest or dividend income earned by a fund’s portfolio.

Inflation — A general increase in prices coinciding with a fall in the real value of money, as measured by the Consumer Price Index.

Interest rate — Rate of interest charged for the use of money, usually expressed at an annual rate.

Market capitalization — Market price multiplied by number of shares outstanding. Whether a company is considered a “large,” “medium” or “small” capitalization company for any particular fund will depend upon the company’s market capitalization at the time of measurement and the index being used and/or the guidelines used by the portfolio manager.

Maturity — The final date on which the payment of a debt instrument (e.g., bonds, notes, repurchase agreements) becomes due and payable. Short-term bonds generally have maturities of up to 5 years; intermediate-term bonds between 5 and 15 years; and long-term bonds over 15 years.

Net assets — A fund’s assets minus its liabilities. With respect to the funds that have a policy to invest 80% of their net assets in particular kinds of securities, “net assets” as used in such policies means net assets plus borrowings made for investment purposes.

Net asset value (NAV) per share — The market value of one share of a fund on any given day without taking into account any front-end sales charge or CDSC. It is determined by dividing a fund’s total net assets by the number of shares outstanding.

Price-to-book value ratio — Current market price of a stock divided by its book value. Some firms use the inverse ratio for this calculation (i.e., book-to-price ratio).

Price-to-earnings ratio — Current market price of a stock divided by its earnings per share. Also known as the “multiple,” the price-to-earnings ratio gives investors an idea of how much they are paying for a company’s earning power and is a useful tool for evaluating the costs of different securities. The ratio may be calculated using “trailing” earnings or estimates of future (or “forward”) earnings. Some firms use the inverse ratio for this calculation (i.e., earnings-to-price ratio).

Qualitative analysis — An analysis of the qualities possessed by a company, including its management, products and competitive positions, to help determine if the company can execute its strategies.

Return on equity — The amount, expressed as a percentage, earned on a company’s common stock investment for a given period. It is calculated by dividing common stock equity (net worth) at the beginning of the accounting period into net income for the period after preferred stock dividends but before common stock dividends. This tells common shareholders how effectively their money is being employed.

Rule 144A securities — Rule 144A securities are privately offered securities that can be resold only to certain qualified institutional buyers. Rule 144A securities are treated as illiquid, unless a manager has determined, under guidelines established by a fund’s trustees, that a particular issue of Rule 144A securities is liquid.

Target price — Price that an investor is hoping a stock he or she has just bought will rise to within a specified period of time. An investor may buy XYZ at $20, with a target price of $40 in one year’s time, for instance.

Technical analysis — The research into the demand and supply for securities, options, mutual funds and commodities based on trading volume and price studies. Technical analysis uses charts or computer programs to identify and project price trends in a market, security, mutual fund or futures contract.

Top-down approach — The method in which an investor first looks at trends in the general economy, and next selects industries and then companies that the investor believes should benefit from those trends.

Total return — The change in value of an investment in a fund over a specific time period expressed as a percentage. Total returns assume all distributions are reinvested in additional shares of a fund.

Value investing — A relatively conservative investment approach that focuses on companies that may be temporarily out of favor or whose earnings or assets are not fully reflected in their stock prices. Value stocks will tend to have a lower price-to-earnings ratio than growth stocks.

GLOSSARY OF TERMS

Volatility — The general variability of a fund’s value resulting from price fluctuations of its investments. In most cases, the more diversified a fund is, the less volatile it will be.

Yield — The rate at which a fund earns income, expressed as a percentage. Mutual fund yield calculations are standardized, based upon a formula developed by the SEC.

Yield-to-maturity — The concept used to determine the rate of return an investor will receive if a long-term, interest-bearing investment, such as a bond, is held to its maturity date. It takes into account purchase price, redemption value, time to maturity, coupon yield (the interest rate on a debt security the issuer promises to pay to the holder until maturity, expressed as an annual percentage of face value) and the time between interest payments.

GOALS, STRATEGIES & RISKS

ASG Global Alternatives Fund


Adviser:	AlphaSimplex Group, LLC (“AlphaSimplex” or the “Adviser”)

Subadviser:	Reich & Tang Asset Management, LLC (“Reich & Tang” or the “Subadviser”)

Managers:	Adviser: Andrew Lo and Jeremiah Chafkin
	Subadviser: Robert Rickard

Investment Goal

The Fund pursues an absolute return strategy that seeks to provide capital appreciation consistent with the return and risk characteristics of a diversified portfolio of hedge funds. The secondary goal of the Fund is to achieve these returns with less volatility than major equity indices. The investment goals are non-fundamental and may be changed without shareholder approval. The Fund will provide 60 days’ prior notice to shareholders before changing the investment goals.

Principal Investment Strategies

The Fund seeks to achieve long and short exposure to global equity, bond, currency and commodity markets through a wide range of derivative instruments and direct investments. Under normal market conditions, the Adviser typically will make extensive use of derivative instruments, in particular futures and forward contracts on global equity and fixed income securities, securities indices (including both broad- and narrow-based securities indices), currencies, commodities and other instruments. These investments are intended to provide the Fund with risk and return characteristics similar to those of a diversified portfolio of hedge funds.

The Fund seeks to generate absolute returns over time rather than track the performance of any particular index of hedge fund returns. In selecting investments for the Fund, the Adviser uses quantitative models to estimate the market exposures that drive the aggregate returns of a diverse set of hedge funds. These market exposures may include, for example, exposures to the returns of stocks, fixed income securities (including U.S. and non-U.S. government securities), currencies and commodities. In estimating these market exposures, the Adviser analyzes the returns of hedge funds included in one or more commercially available databases selected by the Adviser (for example, the Lipper TASS hedge fund database), and seeks to use a variety of derivative instruments to capture such exposures in the aggregate while adding value through dynamic allocation among market exposures and volatility management. The Adviser will have great flexibility to allocate the Fund’s derivatives exposure among various securities, indices, currencies, commodities and other instruments, and the amount of the Fund’s assets that may be allocated to derivative strategies and among these various instruments is expected to vary over time. When buying and selling securities and other instruments for the Fund, and in determining the amount of assets to be allocated to the Money Market Portion (as defined below), the Adviser will also consider the following factors: (i) the Fund’s obligations under its various derivative positions, (ii) redemption requests, (iii) yield management, (iv) credit management and (v) volatility management. The Fund will not invest directly in hedge funds. The Fund may invest in non-U.S. securities and instruments and securities and instruments traded outside the United States and expects to engage in non-U.S. currency transactions.

Under normal market conditions, it is expected that no more than 25% of the Fund’s total assets will be dedicated to initial and variation margin payments relating to the Fund’s derivative transactions. The notional value of the Fund’s derivative investments, however, will generally exceed 25% of the Fund’s assets. Under normal market conditions, the Fund expects to invest no less than 75% of its assets in money market and other short-term, high quality securities managed by the Subadviser (the “Money Market Portion”). The Adviser will determine the percentage of the Fund’s assets that will be invested in the Money Market Portion at any time. The assets allocated to the Money Market Portion will be used primarily to finance the Fund’s investments in derivatives and similar instruments and, secondarily, to provide the Fund with incremental income. Although the Fund will invest a significant portion of its assets in money market instruments, the Fund is


ASG Global Alternatives Fund		1		Prospectus – May 1, 2009

GOALS, STRATEGIES & RISKS

not a “money market” fund and the value of the Money Market Portion as well as the value of the Fund’s shares may decrease. The Fund is not subject to the portfolio quality, maturity and net asset value requirements applicable to money market funds, and the Fund will not seek to maintain a stable net asset value.

The Subadviser will only invest the assets of the Money Market Portion in high quality securities which are denominated in U.S. dollars, and will select securities for investment based on various factors, including the security’s maturity and rating. The Subadviser will invest primarily in (i) short-term obligations issued or guaranteed by the United States Government, its agencies or instrumentalities (“U.S. Government Obligations”), (ii) securities issued by foreign governments, their political subdivisions or agencies or instrumentalities, (iii) certificates of deposit, time deposits and bankers’ acceptances issued by domestic banks, foreign branches of domestic banks, foreign subsidiaries of domestic banks, and domestic and foreign branches of foreign banks, (iv) variable amount master demand notes, (v) participation interests in loans extended by banks to companies, (vi) commercial paper or similar debt obligations and (vii) repurchase agreements.

Although the Fund does not intend to invest in physical commodities directly, the Fund may invest in commodity-related derivatives. The Fund’s commodity-related investments are made through a wholly-owned subsidiary organized under the laws of a non-U.S. jurisdiction (the “Commodity Subsidiary”). Under normal market conditions, no more than 10% of the Fund’s assets will be dedicated to initial and variation margin payments relating to these transactions.

The Fund may concentrate its investments in the financial services industry, which means it will normally invest at least 25% of its assets in securities and other obligations of issuers in such industry.

The Fund may engage in active and frequent trading of securities and other instruments. Effects of frequent trading may include high transaction costs, which may lower the Fund’s return, and realization of greater short-term capital gains, distributions of which are taxable to shareholders who are individuals as ordinary income. Trading costs and tax effects associated with frequent trading may adversely affect the Fund’s performance.

The percentage limitations set forth in this Fund summary are not investment restrictions and the Fund may exceed these limits from time to time. As a temporary defensive measure, the Fund may hold any portion of its assets in cash (U.S. Dollars, foreign currencies or multinational currency units) and/or invest in money market instruments or high quality debt securities and take other defensive positions as the Adviser deems appropriate. The Fund may miss certain investment opportunities if it uses defensive strategies and thus may not achieve its investment goal.

Principal Investment Risks

The principal risks of investing in the Fund are described below. There are other circumstances (including non-principal risks that are not described here) which could prevent the Fund from achieving its investment goals. The Fund does not represent a complete investment program. The Fund’s net asset value may fluctuate substantially over time. You may lose money by investing in the Fund.

Because of the Fund’s extensive use of derivative instruments, the Fund will be subject to many of the risks below indirectly through its derivative transactions rather than directly through investment in the actual securities themselves. For example, to the extent the Fund enters into a futures contract on an equity index, the Fund will be subject to “equity securities” risk.

Credit/Counterparty risk: Credit risk is the risk that the issuer or the guarantor of a fixed-income security, or the counterparty to a derivatives or other transaction, will be unable or unwilling to make timely payments of interest or principal or to otherwise honor its obligations. Lower-rated fixed-income securities are considered predominantly speculative with respect to the ability of the issuer to make timely principal and interest payments. Foreign securities may be subject to increased credit risk because of the potential difficulties of requiring foreign entities to honor their contractual commitments.

The Fund will be subject to credit risks with respect to the counterparties of its derivative transactions. Many of the protections afforded to participants on organized exchanges, such as the performance guarantee of an exchange clearing house, are not available in connection with over-the-counter (“OTC”) derivative transactions, such as foreign currency transactions. As a result, in instances when the Fund enters into OTC derivative transactions, the Fund will be subject to the risk that its direct counterparty will not perform its obligations under the transactions and that the Fund will sustain losses or be unable to realize gains.


ASG Global Alternatives Fund		2		Prospectus – May 1, 2009

GOALS, STRATEGIES & RISKS

Commodity risk: This is the risk that exposure to the commodities markets may subject the Fund to greater volatility than investments in traditional securities. The value of physical commodities or commodity-linked derivative instruments may be affected by changes in overall market movements, commodity price volatility, changes in interest rates, or sectors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments.

Concentrated investment risk: The Fund is particularly vulnerable to events affecting companies in the financial services industry because the Fund concentrates its investments in securities and other obligations of issuers in such industry. Examples of risks affecting the financial services industry include changes in governmental regulation, issues relating to the availability and cost of capital, changes in interest rates and/or monetary policy and price competition. In addition, financial services companies are often more highly leveraged than other companies, making them inherently riskier. As a result, the Fund’s shares may rise and fall in value more rapidly and to a greater extent than shares of a fund that does not concentrate or focus in a particular industry or economic sector. The financial services industry has recently experienced high volatility and a number of issuer failures and the value of many of these securities has significantly declined. As a result, the risk associated with investing in the Fund may be increased as compared to a fund that does not concentrate in the financial services industry.

Currency risk: This is the risk that fluctuations in exchange rates between the U.S. dollar and foreign currencies may cause the value of the Fund’s investments to decline.

Derivatives risk: Derivatives are financial contracts whose value depends upon or is derived from the value of an underlying asset, reference rate or index. Examples of derivatives include futures contracts, swaps and forward transactions. The Fund expects to make extensive use of derivative transactions, and anticipates that the majority of its returns will be attributable to its derivative transactions. Therefore, the performance of the Fund will depend to a great extent on the success of the Adviser’s derivative strategies. This use of derivatives for these purposes entails greater risk than using derivatives solely for hedging purposes. The Fund’s use of derivatives involves other risks, such as the credit risk relating to the other party to a derivative contract, the risk of difficulties in pricing and valuation, the risk that changes in the value of a derivative may not correlate perfectly with relevant assets, rates or indices, and the risk that the Fund’s liquid assets may be insufficient to support its obligations under its derivatives positions.

Equity securities risk: You may lose money on your investment due to unpredictable drops in a stock’s value or periods of below-average performance in a given stock or industry or in the stock market as a whole. Equity securities may include common stocks, preferred stocks, warrants, securities convertible into common or preferred stocks and other equity-like interests in an entity. Common stocks represent an equity or ownership interest in an issuer. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s bonds and preferred stock take precedence over the claims of those who own common stock. Equity securities may take the form of stock in corporations, limited partnership interests or interests in limited liability companies, real estate investment trusts (“REITs”) or other trusts and other similar securities.

Foreign securities risk: This is the risk associated with investments in issuers located in foreign countries. The Fund’s investments in foreign securities may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. The securities markets of many foreign countries are relatively small, with a limited number of issuers and a small number of securities. In addition, foreign companies often are not subject to the same degree of regulation as U.S. companies. Reporting, accounting and auditing standards of foreign countries differ, in some cases significantly, from U.S. standards. Nationalization, expropriation or confiscatory taxation, currency blockage, political changes or diplomatic developments can cause the value of the Fund’s non-U.S. investments to decline. In the event of nationalization, expropriation or other confiscation, the Fund could lose its entire foreign investment. Investments in emerging markets may be subject to these risks to a greater extent than those in more developed markets.

Hedge fund risk: Hedge funds are typically unregulated private investment pools available only to sophisticated investors. They are often illiquid and highly leveraged. Although the Fund will not invest directly in hedge funds, because the Fund’s investments are intended to provide exposure to the factors that drive hedge fund returns, an investment in the Fund will be subject to many of the same risks associated with an investment in a diversified portfolio of hedge funds. Therefore, the Fund’s performance may be lower than the returns of the broader stock market and the Fund’s net asset value may fluctuate substantially over time.


ASG Global Alternatives Fund		3		Prospectus – May 1, 2009

GOALS, STRATEGIES & RISKS

Index/tracking error risk: Although the Fund does not seek to track any particular index, the Fund seeks to analyze the factors that drive hedge fund returns, as determined by reference to one or more indices. These indices may not provide an accurate representation of hedge fund returns generally, and the Adviser’s strategy may not successfully identify or be able to replicate factors that drive returns. There is a risk that hedge fund return data provided by third party hedge fund index providers may be inaccurate or may not accurately reflect hedge fund returns due to survivorship bias, self-reporting bias or other biases. Even if an index does provide an accurate representation of hedge fund returns generally, the Fund’s performance may not match the returns of any such index during any period of time. For example, the Fund’s returns may differ from the returns of an index because of the inability of the Fund’s managers to replicate hedge fund returns (which are based on many different types of assets, including illiquid assets, that may not be available for investment by the Fund) using futures and forward contracts and because of differences in volatility between the Fund’s portfolio and the returns of the index. In addition, unlike an index, the Fund will be subject to a management fee and other Fund-level expenses. Therefore, the returns of the Fund may differ significantly from returns of hedge funds generally, or the returns of any particular index.

Interest rate risk: This is the risk that changes in interest rates will affect the value of the Fund’s investments in fixed-income securities, such as bonds, notes, asset-backed securities and other income-producing securities. Fixed-income securities are obligations of the issuer to make payments of principal and/or interest on future dates. Increases in interest rates may cause the value of the Fund’s investments to decline. Generally, the value of fixed-income securities, including short-term fixed-income securities, rises when prevailing interest rates fall and falls when interest rates rise. A significant change in interest rates could cause the Fund’s share price (and the value of your investment) to change.

Issuer risk: The value of the Fund’s investments may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods and services.

Leverage risk: This is the risk associated with securities or practices (e.g., borrowing and the use of certain derivatives) and investment in certain types of derivatives that multiply small index or market movements into larger changes in value. Use of derivative instruments may involve leverage. When a derivative is used as a hedge against an offsetting position that the Fund also holds, any loss generated by the derivative should be substantially offset by gains on the hedged instrument, and vice versa. To the extent that the Fund uses a derivative for purposes other than as a hedge, or if the Fund hedges imperfectly, the Fund is directly exposed to the risks of that derivative and any loss generated by the derivative will not be offset by a gain. Futures and forward currency contracts are derivatives and may be subject to this type of risk. Although the Adviser will seek to manage the Fund’s risk from the leverage associated with derivative investments by closely monitoring the volatility of such investments, the Adviser may not be successful in this respect.

Liquidity risk: Liquidity risk exists when particular investments are difficult to purchase or sell, possibly preventing the Fund from selling these illiquid securities at an advantageous price or at the time desired. A lack of liquidity may also cause the value of investments to decline. Derivatives and securities that involve substantial interest rate or credit risk tend to involve greater liquidity risk. In addition, liquidity risk tends to increase to the extent the Fund invests in securities whose sale may be restricted by law or by contract, such as Rule 144A securities. Investment in derivatives may be especially illiquid when compared to other securities, especially during periods of market stress. Similarly, at certain times, the market for money market and similar instruments may become illiquid. At these times, it may be difficult to sell securities. Illiquid investments may also be difficult to value.

Management risk: Management risk is the risk that the Adviser’s or Subadviser’s investment techniques could fail to achieve the Fund’s objective and could cause your investment in the Fund to lose value. The Fund is subject to management risk because the Fund is actively managed. The Adviser and Subadviser will apply their investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that such decisions will produce the desired results. For example, securities that the Adviser or Subadviser expect may appreciate in value may in fact decline. Similarly, in some cases derivative and other investment techniques may be unavailable or the Adviser or Subadviser may determine not to use them, even under market conditions where their use could have benefited the Fund.

Market risk: This is the risk that the value of the Fund’s investments will change as financial markets fluctuate and that prices overall may decline. The value of a company’s securities may fall as a result of factors that directly relate to that company, such as decisions made by its management or lower demand for the company’s products or services. A security’s value also may fall because of factors affecting not just the company, but companies in its industry or in a number of

GOALS, STRATEGIES & RISKS

different industries, such as increases in production costs. In addition, the value of the Fund’s derivative investments may fall even when the value of the securities markets is rising. The value of a company’s securities also may be affected by changes in financial market conditions, such as changes in interest rates or currency exchange rates.

Valuation risk: The risk that the Fund has valued certain securities at a higher price than the price at which they can be sold. This risk may be especially pronounced for investments, such as derivatives, which may be illiquid or which may become illiquid.

For additional information, see the section “More About Risk.”

Evaluating the Fund’s Past Performance

•

Your investment has a 5% return each year;

•

The Fund’s operating expenses remain the same; and

•

All dividends and distributions are reinvested.

Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

FUND FEES & EXPENSES

1	A reduced sales charge on Class A shares applies in some cases. See the section “How Sales Charges Are Calculated” within the section “Fund Services.”

2	Does not apply to reinvested dividends or other distributions.

4	Includes an estimate of 0.12% of management fees borne by the Fund through investments made through the Commodity Subsidiary.

5	“Other expenses” are based on estimated amounts for the current fiscal year. “Other expenses” include 0.38% of estimated expenses borne by the Fund through investments made through the Commodity Subsidiary and 0.04% of estimated interest expense.

The Adviser has given a binding contractual undertaking to the Fund to limit the amount of the Fund’s total annual fund operating expenses, exclusive of brokerage expenses, expenses estimated to be indirectly borne by the Fund through investments in certain pooled investment vehicles (“Acquired Fund Fees and Expenses”), interest expense, taxes and extraordinary expenses, such as litigation and indemnification expenses, to 1.60% and 2.35% of the Fund’s average daily net assets for Class A and C shares, respectively. This undertaking is in effect through April 30, 2010 and may be terminated only with the consent of the Board of Trustees. However, the Board of Trustees does not intend to terminate this undertaking. The Fund’s Adviser will be permitted to recover, on a class by class basis, management fees reduced and/or expenses reimbursed it has borne through the undertakings described in this footnote to the extent that a class’ expenses in later periods fall below the annual rates set forth in the relevant undertaking. The Adviser may not recover any such reduced fees and expenses with respect to a class more than one year after the end of the fiscal year in which the fee/expense was deferred. Without this undertaking, expenses would be higher.

7	Assumes redemption at end of period.

8	Assumes no redemption at end of period.

*	Generally, a transaction fee will be charged for expedited payment of redemption proceeds of $5.50 for wire transfers or $20.50 for overnight delivery. These fees are subject to change.

**	Because of the higher service and distribution (12b-1) fees, long-term shareholders may pay more than the economic equivalent of the maximum front-end sales charge permitted by the rules of the Financial Industry Regulatory Authority.

***	The example is based on the estimated Net Expenses for the first year illustrated in the example and on the estimated Total Annual Fund Operating Expenses for the remaining years.

A “snapshot” of the Fund’s investments may be found in its annual and semiannual reports. In addition, a list of the Fund’s full portfolio holdings, which is updated monthly after an aging period of at least 7 days, is available on the Fund’s website at www.funds.natixis.com (click on “Fund Information” and then “Portfolio Holdings”). These holdings will remain accessible on the website until the Fund files its Form N-CSR or Form N-Q with the Securities and Exchange Commission (the “SEC”) for the period that includes the date of the information.

More About Risk

The Fund has principal investment strategies that come with inherent risks. The principal risks of investing in the Fund are described in the Fund summary under “Principal Investment Risks.” The following is a list of non-principal risks to which the Fund may be subject because of its investment in various types of securities or engagement in various practices. Because of the Fund’s extensive use of derivative investments, the Fund will be subject to many of the risks below indirectly through its derivative transactions rather than directly through investment in the securities themselves.

Commodity Subsidiary Risk

The risk associated with investing in a wholly-owned commodity subsidiary organized under the laws of a non-U.S. jurisdiction, such as the Commodity Subsidiary, which may indirectly expose the Fund to the risks associated with the subsidiary’s investments. The Commodity Subsidiary is not registered under the Investment Company Act of 1940 (the “1940 Act”), and unless otherwise noted, is not subject to all of the investor protections of the 1940 Act. However, the Commodity Subsidiary is wholly-owned and controlled by the Fund and therefore, it is unlikely that the Commodity Subsidiary will take action contrary to the interests of the Fund or its shareholders. In monitoring compliance with its investment restrictions, the Fund will consider the assets of the Commodity Subsidiary to be assets of the Fund. Changes in the laws of the United States and/or the Cayman Islands, under which the Fund and the Commodity Subsidiary, respectively, are organized, could negatively affect the Fund and its shareholders. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax, estate duty, inheritance tax, gift tax or withholding tax on the Commodity Subsidiary. If Cay-man Islands law changes such that the Commodity Subsidiary is required to pay Cayman Islands taxes, the Fund shareholders may suffer decreased investment returns.

Emerging Markets Risk

Fixed-Income Securities Rated Below Investment Grade Risk

Fixed-income securities rated below investment grade, commonly known as “junk bonds,” may be considered speculative with respect to the issuer’s continuing ability to make principal and interest payments. The issuers of these securities may be in default or have a currently identifiable vulnerability to default on their payments of principal and interest, or may otherwise be subject to present elements of danger with respect to payments of principal or interest. Securities rated below investment grade may be more susceptible to real or perceived adverse economic and competitive industry conditions than higher grade securities.

The secondary markets in which lower-rated securities are traded may be less liquid than the market for higher grade securities. A lack of liquidity in the secondary trading markets could adversely affect the price at which the Fund could sell a particular lower-rated security. Adverse publicity and investor perceptions may decrease the values and liquidity of high yield securities generally.

Inflation/Deflation Risk

Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the present value of future payments. Deflation risk is the risk that prices throughout the economy decline over time (the opposite of inflation). Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund’s portfolio.

Information Risk

The risk that key information about a security or other instrument is inaccurate or unavailable.


ASG Global Alternatives Fund		8		Prospectus – May 1, 2009

MORE ABOUT RISK

Mortgage-Related Securities Risk

Mortgage-related securities, such as Government National Mortgage Association certificates or securities issued by the Federal National Mortgage Association, differ from traditional fixed-income securities. Among the major differences are that interest and principal payments are made more frequently, usually monthly, and that principal may be prepaid at any time because the underlying mortgage loans generally may be prepaid at any time. As a result, if the Fund purchases these assets at a premium, a faster-than-expected prepayment rate will reduce yield to maturity, and a slower-than-expected prepayment rate will increase yield to maturity. If the Fund purchases mortgage-related securities at a discount, faster-than-expected prepayments will increase, and slower-than-expected prepayments will reduce, yield to maturity. Prepayments, and resulting amounts available for reinvestment by the Fund, are likely to be greater during a period of declining interest rates and, as a result, are likely to be reinvested at lower interest rates. Accelerated prepayments on securities purchased at a premium may result in a loss of principal if the premium has not been fully amortized at the time of prepayment. These securities will decrease in value as a result of increases in interest rates generally, and they are likely to appreciate less than other fixed-income securities when interest rates decline because of the risk of prepayments.

The market for mortgage-backed securities (and other asset-backed securities) has experienced high volatility and a lack of liquidity. As a result, the value of many of these securities has significantly declined. There can be no assurance that these markets will become more liquid or less volatile, and it is possible that the value of these securities could decline further.

Opportunity Risk

The risk of missing out on an investment opportunity because the assets necessary to take advantage of it are invested in less profitable investments.

Political Risk

The risk of losses directly attributable to government or political actions.

Repurchase Agreement Risk

Under a repurchase agreement, a fund purchases a security and obtains a simultaneous commitment from the seller (a bank or, to the extent permitted by the 1940 Act, a recognized securities dealer) to repurchase the security at an agreed upon price and date (usually seven days or less from the date of original purchase). The resale price is in excess of the purchase price and reflects an agreed-upon market rate of interest unrelated to the coupon rate on the purchased security. Such transactions afford the Fund the opportunity to earn a return on its cash at minimal market risk. There is a risk that the seller may fail to repurchase the underlying security. In such event, the Fund would attempt to exercise rights with respect to the underlying security, including possible disposition in the market. However, the Fund may be subject to various delays and risks of loss, including possible declines in the value of the underlying security, possible reduced levels of income, inability to enforce rights and expenses involved in attempted enforcement. Repurchase agreements maturing in more than seven days may be considered illiquid securities.

U.S. Government Securities Risk

Investments in certain U.S. Government securities may not be supported by the full faith and credit of the U.S. Government. Accordingly, no assurance can be given that the U.S. Government will provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. The maximum potential liability of the issuers of some U.S. Government securities held by the Fund may greatly exceed their current resources, and it is possible that these issuers will not have the funds to meet their payment obligations in the future. In such a case, the Fund would have to look principally to the agency, instrumentality or sponsored enterprise issuing or guaranteeing the security for ultimate repayment, and the Fund may not be able to assert a claim against the U.S. Government itself in the event the agency, instrumentality or sponsored enterprise does not meet its commitment.

Meet the Fund’s Investment Adviser and Subadviser

The Natixis Funds family (as defined below) currently includes 23 mutual funds. The Natixis Funds family had combined assets of $21.4 billion as of December 31, 2008. Natixis Funds are distributed through Natixis Distributors, L.P. (the “Distributor”). This Prospectus covers the ASG Global Alternatives Fund (the “Fund”), which, along with the Natixis Equity Funds, Natixis Income Funds, Natixis Income Diversified Portfolio, Loomis Sayles Global Markets Fund, Loomis Sayles Growth Fund, Loomis Sayles Mid Cap Growth Fund, Loomis Sayles Research Fund, Loomis Sayles Value Fund, Loomis Sayles Strategic Income Fund, Natixis Cash Management Trust — Money Market Series (the “Money Market Fund”), Gateway Fund, Delafield Select Fund and Vaughan Nelson Value Opportunity Fund constitute the “Natixis Funds.”

Adviser and Subadviser

AlphaSimplex Group, LLC (“AlphaSimplex”), located at One Cambridge Center, Cambridge, Massachusetts 02142, serves as the adviser to the Fund. The Adviser is a subsidiary of Natixis Global Asset Management, L.P. (“Natixis US”), which is part of Natixis Global Asset Management, L.P., an international asset management group based in Paris, France. Natixis Global Asset Management is ultimately owned principally, directly or indirectly, by three large French financial services entities: Natixis, an investment banking and financial services firm; the Caisse Nationale des Caisses d’Epargne, a financial institution owned by French regional savings banks known as the Caisses d’Epargne; and Banque Fédérale des Banques Populaires, a financial institution owned by regional cooperative banks known as the Banques Populaires. Natixis US has 15 principal subsidiary or affiliated asset management firms that collectively had over $214 billion in assets under management as of December 31, 2008. The Adviser was founded in 1999 and as of December 31, 2008, it serves as investment adviser or subadviser with respect to assets of $707 million (including notional assets covered by overlay strategies).

Reich & Tang, located at 600 Fifth Avenue, New York, New York 10020, serves as the subadviser to the Fund. Reich & Tang is a limited liability company with 100% of its membership interest owned by Natixis US. Reich & Tang’s origins date back to 1970, and as of December 31, 2008, it is the investment manager, adviser or subadviser with respect to assets in excess of $14.3 billion.

The aggregate advisory and subadvisory fees paid by the Fund for the fiscal year ended December 31, 2008, as a percentage of the Fund’s average daily net assets, were 0.00% (after reduction).

A discussion of the factors considered by the Board of Trustees in approving the Fund’s investment advisory agreement and sub-advisory agreement is included in the Fund’s initial shareholder report for the period ended December 31, 2008.

Portfolio Trades

In placing portfolio trades, the Adviser and Subadviser may use brokerage firms that market the Fund’s shares or are affiliated with Natixis US and the Adviser. In placing trades, the Adviser and Subadviser will seek to obtain the best combination of price and execution, which involves a number of subjective factors. Such portfolio trades are subject to applicable regulatory restrictions and related procedures adopted by the Board of Trustees.

Transactions with Other Investment Companies. Pursuant to SEC exemptive relief, the Fund may be permitted to invest its daily cash balances in shares of money market and short-term bond funds advised by Natixis Asset Management Advisors, L.P. (“Natixis Advisors”) or its affiliates (“Central Funds”). The Central Funds currently include the Money Market Fund and Daily Income Fund. Daily Income Fund is advised by Reich & Tang, and the Money Market Fund is advised by Natixis Advisors and subadvised by Reich & Tang. Because Natixis Advisors, Reich & Tang and AlphaSimplex are each subsidiaries of Natixis US, the Fund and the Central Funds may be considered to be related companies comprising a “group of investment companies” under the 1940 Act. The Fund may also make investments in related investment companies to the extent permitted by SEC regulation.


ASG Global Alternatives Fund		10		Prospectus – May 1, 2009

MANAGEMENT TEAM

Pursuant to such exemptive relief, the Fund may also borrow and lend money for temporary or emergency purposes directly to and from other funds through an interfund credit facility (the “Credit Facility”). In addition to the Fund and the Central Funds, series of the following mutual fund groups may also be able to participate in the facility: Natixis Funds Trust I (except the CGM Advisor Targeted Equity Fund series), Natixis Funds Trust II, Natixis Funds Trust III, Natixis Funds Trust IV, Harris Associates Investment Trust, Loomis Sayles Funds I, Loomis Sayles Funds II and Gateway Trust. The advisers and subadvisers to these mutual funds currently include Natixis Advisors, Reich & Tang, Loomis, Sayles & Company, L.P., AEW Capital Management, L.P., AlphaSimplex, BlackRock Investment Management, LLC (“BlackRock”), Gateway Investment Advisers, LLC, Harris Associates L.P., Hansberger Global Investors, Inc. and Vaughan Nelson Investment Management, L.P. Each of these advisers and subadvisers (except for BlackRock) are subsidiaries of Natixis US and are thus “affiliated persons” under the 1940 Act by reason of being under common control by Natixis US. In addition, because the Fund and other funds are advised by firms that are affiliated with one another, they may be considered to be related companies comprising a “group of investment companies” under the 1940 Act. The Central Funds will participate in the Credit Facility only as lenders. Participation in such an interfund lending program would be voluntary for both borrowing and lending funds, and the Fund would participate in an interfund lending program only if the Board of Trustees determined that doing so would benefit the Fund. Should the Fund participate in such an interfund lending program, the Board of Trustees would establish procedures for the operation of the program by the advisers or an affiliate. The Fund may engage in the transactions described above without further notice to shareholders.

Investing in the Fund

Choosing a Share Class

The Fund offers Class A and Class C shares to the public. Each class has different costs associated with buying, selling and holding Fund shares, which allows you to choose the class that best meets your needs. Which class is best for you depends upon the size of your investment and how long you intend to hold your shares. Class C shares and certain shareholder features may not be available to you if you hold your shares in a street name account. Your financial representative can help you decide which class of shares is most appropriate for you.

Class A Shares

•

You pay a sales charge when you buy Class A shares. There are several ways to reduce this charge. See the section “How Sales Charges Are Calculated.”

•

You pay lower annual expenses than Class C shares, giving you the potential for higher returns per share. However, where front-end sales charges are applicable, returns are earned on a smaller amount of your investment.

•

You do not pay a sales charge on orders of $1 million or more, but you may pay a charge on redemptions if you redeem these shares within one year of purchase.

Class C Shares

•

You do not pay a sales charge when you buy Class C shares. All of your money goes to work for you right away.

•

You pay higher annual expenses than Class A shares.

•

You may pay a sales charge on redemptions if you sell your shares within one year of purchase.

•

Your Class C shares will not automatically convert into Class A shares. If you hold your shares for longer than eight years, you will pay higher expenses than shareholders of other classes.

•

For information about the Fund’s expenses, see the section “Fund Fees & Expenses” in this Prospectus.

Certificates

Certificates will not be issued for any class of shares.

How Sales Charges are Calculated

Class A Shares


	Class A Sales Charges**
Your Investment	As a % of offering price		As a % of your investment
Less than $ 50,000	5.75	%	6.10	%
$ 50,000 – $ 99,999	4.50	%	4.71	%
$ 100,000 – $ 249,999	3.50	%	3.63	%
$ 250,000 – $ 499,999	2.50	%	2.56	%
$ 500,000 – $ 999,999	2.00	%	2.04	%
$ 1,000,000 or more*	0.00	%	0.00	%

Due to rounding, the actual sales charge for a particular transaction may be higher or lower than the rates listed above.

*	For purchases of Class A shares of the Fund of $1 million or more, there is no front-end sales charge, but a CDSC of 1.00% may apply to redemptions of your shares within one year of the date of purchase. See the section “How the CDSC is Applied to Your Shares.”

**	Not imposed on shares that are purchased with reinvested dividends or other distributions.

Reducing Front-End Sales Charges

There are several ways you can lower your sales charge for Class A shares, including:

•

Cumulative Purchase Discount — You may be entitled to a reduced sales charge if your “total investment” reaches a breakpoint for a reduced sales charge. The total investment is determined by adding the amount of your current purchase in the Fund, including the applicable sales charge, to the current public offering price of all series and classes of shares of the Natixis Funds held by you in one or more accounts. If your total investment exceeds a sales charge breakpoint in the table above, the lower sales charge applies to the entire amount of your current purchase in the Fund.

•

Combining Accounts — This allows you to combine shares of multiple Natixis Funds and classes for purposes of calculating your sales charge.


ASG Global Alternatives Fund		13		Prospectus – May 1, 2009

FUND SERVICES

The above-listed ways to reduce front-end sales charges may not apply to the Money Market Fund unless shares are purchased through an exchange from another Natixis Fund.

Eliminating Front-End Sales Charges and CDSCs

Class A shares may be offered without front-end sales charges or a CDSC to the following individuals and institutions:

•

Any government entity that is prohibited from paying a sales charge or commission to purchase mutual fund shares;

•

Selling brokers, sales representatives, registered investment advisers, financial planners or other intermediaries under arrangements with the Distributor;

•

Participants in certain retirement plans with at least $1 million or more in total plan assets or with 100 eligible employees;

•

Non-discretionary and non-retirement accounts of bank trust departments or trust companies, but only if they principally engage in banking or trust activities;

•

Clients of an adviser or subadviser to any Natixis Fund (including the Money Market Fund) with investments of $25,000 or more in the Natixis Funds; and

•

Clients of Natixis Advisors that invest in a Natixis Fund that does not offer Class Y shares.

In order to receive Class A shares without a front-end sales charge or a CDSC, you must notify the Fund of your eligibility at the time of purchase.

Repurchasing Fund Shares

You may apply proceeds from redeeming Class A shares of the Fund to repurchase Class A shares of any Natixis Fund without paying a front-end sales charge. To qualify, you must reinvest some or all of the proceeds within 120 days after your redemption and notify Natixis Funds in writing (directly or through your financial representative) at the time of reinvestment that you are taking advantage of this privilege. You may reinvest your proceeds by sending a new check for some or all of the redemption amount. Please note: for federal income tax purposes, a redemption is a sale that involves tax consequences, even if the proceeds are later reinvested. Please consult your tax adviser to discuss how a redemption would affect you.

Eliminating the CDSC

Please see the SAI for more information on eliminating or reducing front-end sales charges and CDSC.

Eliminating the CDSC

Please see the SAI for more information on eliminating or reducing front-end sales charges and the CDSC.

How the CDSC is Applied to Your Shares

The CDSC is a sales charge you pay when you redeem certain Fund shares. The CDSC:

•

is calculated based on the number of shares you are selling;

•

is based on either your original purchase price or the current net asset value of the shares being sold, whichever is lower;

•

is deducted from the proceeds of the redemption unless you request, at the time of the redemption, that it be deducted from the amount remaining in your account; and

•

applies to redemptions made through the date of their acquisition for years one through six, as applicable.

A CDSC will not be charged on:

•

increases in net asset value above the purchase price; or

•

shares you acquired by reinvesting your dividends or capital gains distributions.

Exchanges into Shares of the Money Market Fund

If you exchange Class C shares of the Fund into shares of the Money Market Fund, the holding period for purposes of determining the CDSC for Class C shares stops until you exchange back into shares of another Natixis Fund. If you choose to redeem those Money Market Fund shares, a CDSC may apply.

Compensation to Securities Dealers

As part of its business strategies, the Fund pays securities dealers and other financial institutions (collectively, “dealers”) that sell its shares. This compensation originates from two sources: sales charges (front-end or deferred) and 12b-1 fees (comprising the annual service and/or distribution fees paid under a plan adopted pursuant to Rule 12b-1 under the 1940 Act). The sales charges, some or all of which may be paid to dealers, are discussed in the section “How Sales Charges Are Calculated” and dealer commissions as a percentage of offering price is disclosed in the Fund’s SAI. The Fund’s Class A and Class C shares pay an annual service fee of 0.25% of its average daily net assets. Class C shares are subject to an annual distribution fee of 0.75% of their average daily net assets. Generally, the 12b-1 fees are paid to securities dealers on a quarterly basis, but may be paid on other schedules. The Distributor retains the first year of such fees for Class C shares. Because these distribution fees and service fees are paid out of the Fund’s assets on an ongoing basis, over time these fees for Class C shares will increase the cost of your investment and may cost you more than paying the front-end sales charge and service fees on Class A shares.


ASG Global Alternatives Fund		15		Prospectus – May 1, 2009

FUND SERVICES

The Distributor, the Fund’s adviser and their affiliates may, out of their own resources, which generally come directly or indirectly from fees paid by the Fund, make payments to certain dealers and other financial intermediaries that satisfy certain criteria established from time to time by the Distributor. Payments may vary based on sales, the amount of assets a dealer’s or intermediary’s clients have invested in the Fund, and other factors. These payments may also take the form of sponsorship of seminars or informational meetings or payments for attendance by persons associated with a dealer or intermediary at informational meetings. The Distributor and its affiliates may also make payments for recordkeeping and other transfer agency-related services to dealers and intermediaries that sell Fund shares.

The payments described in this section, which may be significant to the dealers and the financial intermediaries, may create an incentive for a dealer or financial intermediary or their representatives to recommend or sell shares of a particular fund or share class over other mutual funds or share classes. Additionally, these payments may result in certain marketing or servicing advantages that are not generally available to mutual funds that do not make such payments, including placement on a sales list, including a preferred or select sales list, or in other sales programs. These payments may create potential conflicts of interest between an investor and a dealer or other financial intermediary who is recommending a particular mutual fund over other mutual funds. Before investing, you should consult with your financial representative and review carefully any disclosure by the dealer or other financial intermediary as to what monies it receives from mutual fund advisers and distributors, as well as how your financial representative is compensated. Please see the SAI for additional information about payments made by the Distributor and its affiliates to dealers and intermediaries. Please also contact your dealer or financial intermediary for details about payments it may receive.

FUND SERVICES

Minimum Balance Policy

The Fund, on an annual basis, may deduct a minimum balance fee of $20 for accounts that fall below the minimum amount required to establish an account, as described above. The minimum balance fee is assessed by the automatic redemption of shares in the account in an amount sufficient to pay the fee. The valuation of account balances for this purpose and the deduction of the fee generally occur during September of each calendar year, although they may occur at another date in the year. The fee will not be deducted from Fund positions opened after June 30th of the calendar year in which the fee is assessed. Certain accounts using a Natixis Funds’ prototype document (including IRAs, Keogh plans, 403(b)(7) plans and Coverdell Education Savings Accounts) and accounts associated with defined contribution plans, are excepted from the minimum balance fee.

In its discretion, the Fund may also close an account and send the account holder the proceeds if the account falls below the minimum amount required to establish an account. The valuation of account balances for this purpose and the liquidation itself generally occur during October of each calendar year, although they may occur at another date in the year. Any account opened after June 30th of a calendar year will not be subject to the liquidation for that calendar year. Certain accounts, such as accounts associated with wrap-fee programs or defined contribution plans are excepted from the liquidation. The determination of whether to deduct the minimum balance fee or close an account is made at the discretion of the Fund.

It is expected that accounts maintained by intermediaries through the National Securities Clearing Corporation may be liquidated rather than assessed a fee if the account balance falls below such minimum and that directly registered accounts may be assessed a fee rather than be liquidated.

In general, you may exchange shares of your Fund for shares of the same class of another Natixis Fund or Loomis Sayles Fund that offers such class of shares, without paying a sales charge or a CDSC (see the sections “Buying Shares” and “Selling Shares”) subject to certain restrictions noted below. For exchanges into the Money Market Fund, the holding period for determining the CDSC, if applicable, for Class C Shares will stop and will resume only when an exchange into an applicable fund occurs. The exchange must be for at least the minimum to open an account (or the total net asset value of your account, whichever is less), or, once the fund minimum is met, exchanges under the Automatic Exchange Plan must be made for at least $100 (see the section “Additional Investor Services”). All exchanges are subject to the eligibility requirements of the fund into which you are exchanging and any other limits on sales of or exchanges into that fund. The exchange privilege may be exercised only in those states where shares of such funds may be legally sold. For federal income tax purposes, an exchange of fund shares for shares of another fund is generally treated as a sale on which gain or loss may be recognized. Subject to the applicable rules of the SEC, the Board of Trustees reserves the right to modify the exchange privilege at any time. Before requesting an exchange into any other fund, please read its prospectus carefully. You may be unable to hold your shares through the same financial intermediary if you engage in certain share exchanges. You should contact your financial intermediary for further details. Please refer to the SAI for more detailed information on exchanging Fund shares.

Restrictions on Buying, Selling and Exchanging Shares

The Fund discourages excessive, short-term trading that may be detrimental to the Fund and its shareholders. Frequent purchases and redemptions of Fund shares by shareholders may present certain risks for other shareholders in the Fund. This includes the risk of diluting the value of Fund shares held by long-term shareholders, interfering with the efficient management of the Fund’s portfolio, and increasing brokerage and administrative costs. Funds investing in securities that require special valuation processes (such as foreign securities, high yield securities, or small cap securities) may also have increased exposure to these risks. The Board of Trustees has adopted the following policies to address and discourage such trading.

The Fund reserves the right to suspend or change the terms of purchasing or exchanging shares. The Fund and the Distributor reserve the right to reject any purchase or exchange order for any reason, including if the transaction is deemed not to be in the best interests of the Fund’s other shareholders or possibly disruptive to the management of the Fund. A shareholder whose exchange order has been rejected may still redeem its shares by submitting a redemption request as described above under “Selling Shares.”

Limits on Frequent Trading. Without limiting the right of the Fund and the Distributor to reject any purchase or exchange order, the Fund and the Distributor may (but are not obligated to) restrict purchases and exchanges for the accounts of “market timers.” An account may be deemed to be one of a market timer if it makes two “round trips” in the Fund over a 90-day interval, as determined by the Fund. A “round trip” is a purchase (including a purchase by exchange) into the Fund followed by a redemption (including a redemption by exchange) of any amount out of the Fund. The above limits are applicable whether you hold shares directly with the Fund or indirectly through a financial intermediary, such as a broker, bank, investment adviser, recordkeeper for retirement plan participants, or other third party. The preceding is not an exclusive description of activities that the Fund and the Distributor may consider to be “market timing.”

Notwithstanding the above, certain financial intermediaries, such as retirement plan administrators, may monitor and restrict the frequency of purchase and redemption transactions in a manner different from that described above. The policies of these intermediaries may be more or less restrictive than the generally applicable policies described above. The Fund may choose to rely on a financial intermediary’s restrictions on frequent trading in place of the Fund’s own restrictions if the Fund determines, in its discretion, that the financial intermediary’s restrictions provide reasonable protection for the Fund from excessive short-term trading activity. Please contact your financial representative for additional information regarding their policies for limiting the frequent trading of Fund shares.

This policy also does not apply with respect to shares purchased by certain funds-of-funds or similar asset allocation programs that rebalance their investments only infrequently. To be eligible for this exemption, the fund-of-funds or asset allocation program must identify itself to and receive prior written approval from the Fund or the Distributor. The Fund and Distributor may request additional information to enable them to determine that the fund-of-funds or asset allocation program is not designed to and/or is not serving as a vehicle for disruptive short-term trading, which may include requests for (i) written assurances from the sponsor or investment manager of the fund-of-funds or asset allocation program that it enforces the Fund’s frequent trading policy on investors or another policy reasonably designed to deter disruptive short-term trading in Fund shares, and/or (ii) data regarding transactions by investors in the fund-of-funds or asset allocation program, for periods and on a frequency determined by the Fund and Distributor, so that the Fund can monitor compliance by such investors with the trading limitations of the Fund or of the fund-of-funds or asset allocation program.

omnibus account level. If the Fund and the Distributor detect suspicious activity, they may request and receive personal identifying information and transaction histories for some or all underlying shareholders (including plan participants) to determine whether such shareholders have engaged in market timing or other excessive, short-term trading activity. If the Fund believes that a shareholder has engaged in market timing or other excessive, short-term trading activity in violation of the Fund’s policies through an omnibus account, the Fund will attempt to limit transactions by the underlying shareholder which engaged in such trading, although it may be unable to do so. The Fund may also limit or prohibit additional purchases of Fund shares by an intermediary. Investors should not assume the Fund will be able to detect or prevent all market timing or other trading practices that may disadvantage the Fund.

Purchase Restrictions

The Fund is required by federal regulations to obtain certain personal information from you and to use that information to verify your identity. The Fund may not be able to open your account if the requested information is not provided. The Fund reserves the right to refuse to open an account, close an account and redeem your shares at the then current price or take other such steps that the Fund deems necessary to comply with federal regulations if your identity cannot be verified.

Selling Restrictions

The table below describes restrictions placed on selling shares of the Fund. Please see the SAI for additional information regarding redemption payment policies:


Restriction	Situation
The Fund may suspend the right of redemption or postpone payment for more than 7 days:	•	When the New York Stock Exchange (the “NYSE”) is closed (other than a weekend/holiday) as permitted by the SEC.

	•	During an emergency as permitted by the SEC.

	•	During any other period permitted by the SEC.

The Fund reserves the right to suspend account services or refuse transaction requests:	•	With a notice of a dispute between registered owners or death of a registered owner.

	•	With suspicion/evidence of a fraudulent act.

The Fund may pay the redemption price in whole or in part by a distribution in kind of readily marketable securities in lieu of cash or may take up to 7 days to pay a redemption request in order to raise capital:	•	When it is detrimental for the Fund to make cash payments as determined in the sole discretion of the adviser or subadviser.




The Fund may withhold redemption proceeds for 10 days from the purchase date:	•	When redemptions are made within 10 calendar days of purchase by check or ACH to allow the check or ACH transaction to clear.

Although most redemptions are made in cash, as described in the SAI, the Fund reserves the right to redeem shares in kind. If a shareholder receives a distribution in kind, the shareholder will bear the market risk associated with the distributed securities and may incur brokerage or other charges in converting the securities to cash.

How Fund Shares Are Priced

“Net asset value” is the price of one share of the Fund without a sales charge, and is calculated each business day using this formula:


Net Asset Value =		Total market value of securities + Cash and other assets – Liabilities
Net Asset Value =		Number of outstanding shares

The net asset value of Fund shares is determined pursuant to policies and procedures approved by the Board of Trustees, as summarized below:

•

Requests received by the Fund after the NYSE closes will be processed based upon the net asset value determined at the close of regular trading on the next day that the NYSE is open. If the transfer agent receives the order in good order by 4:00 p.m., Eastern time, the shareholder will receive that day’s net asset value. Under limited circumstances, the Distributor may enter into contractual agreements pursuant to which orders received by your investment dealer before the Fund determines its net asset value (normally 4:00 p.m., Eastern time) are processed at the net asset value determined on the day the order was received by your investment dealer. Please contact your investment dealer to determine whether it has entered into such a contractual agreement. If your investment dealer has not entered into such a contractual agreement, your order will be processed at the net asset value next determined after your investment dealer submits the order to the Fund.

•

A fund that invests in foreign securities may have net asset value changes on days when you cannot buy or sell its shares.

1	Please see the section “Buying Shares”, which provides additional information regarding who can receive a purchase order.

Generally, Fund securities are valued as follows:

•

Equity securities — last sale price on the exchange or market where primarily traded or, if there is no reported sale during the day, the closing bid price.

•

Debt securities (other than short-term obligations) — based upon evaluated prices furnished to the Fund by an independent pricing service, which service determines valuations for normal, institutional-size trading units of such securities using market information, transactions for comparable securities and various relationships between securities which are generally recognized by institutional traders.

•

Short-term obligations (purchased with an original or remaining maturity of 60 days or less) — amortized cost (which approximates market value).

•

Securities traded on foreign exchanges — market price on the foreign exchange, unless the Fund believes that an occurrence after the close of that exchange will materially affect the security’s value. In that case, the security may be fair valued at the time the Fund determines its net asset value by or pursuant to procedures approved by the Board of Trustees. When fair valuing their securities, the Fund may, among other things, use modeling tools or other processes that may take into account factors such as securities market activity and/or significant events that occur after the close of the local market and before the time the Fund’s net asset value is calculated.

•


ASG Global Alternatives Fund		23		Prospectus – May 1, 2009

FUND SERVICES

•

Futures — current settlement price.

•

Foreign Currency Forward Contracts — interpolated prices determined based on information provided by an independent pricing service.

•

All other securities — fair market value as determined by the adviser or subadviser of the Fund pursuant to procedures approved by the Board of Trustees.

As described above, if market prices are not readily available for a security, securities may not be priced on the basis of quotations from the primary market in which they are traded but rather may be priced by another method that the Board of Trustees believes is more likely to result in a price that reflects fair value (which is the amount that the Fund might reasonably expect to receive from a current sale of the security in the ordinary course of business). The Fund may also value securities at fair value or estimate their value pursuant to procedures approved by the Board of Trustees in other circumstances such as when extraordinary events occur after the close of the relevant market but prior to the close of the NYSE. This may include situations relating to a single issuer (such as a declaration of bankruptcy or a delisting of the issuer’s security from the primary market on which it has traded) as well as events affecting the securities markets in general (such as market disruptions or closings and significant fluctuations in U.S. and/or foreign markets). Fair value pricing may require subjective determinations about the value of a security, and fair values used to determine the Fund’s net asset value may differ from quoted or published prices, or from prices that are used by others, for the same securities. In addition, the use of fair value pricing may not always result in adjustments to the prices of securities held by the Fund.

Dividends and Distributions

The Fund generally distributes most or all of its net investment income (other than capital gains) in the form of dividends. The Fund expects to distribute dividends annually. The Fund expects to distribute all or substantially all of its net realized long- and short-term capital gains annually, after applying any available capital loss carryovers. To the extent permitted by law, the Board of Trustees may adopt a different schedule for making distributions as long as payments are made at least annually.

Distributions will automatically be reinvested in shares of the same class of the distributing Fund at net asset value, unless you select one of the following alternatives:

•

Receive all distributions in cash.

For more information or to change your distribution option, contact Natixis Funds in writing or call 800-225-5478.

If you earn more than $10 annually in taxable income from a Natixis Fund held in a non-retirement plan account, you will receive a Form 1099 to help you report the prior calendar year’s distributions on your federal income tax return. This information will also be reported to the Internal Revenue Service (“IRS”). Be sure to keep this Form 1099 as a permanent record. A fee may be charged for any duplicate information requested.

Tax Consequences

Except where noted, the discussion below addresses only the U.S. federal income tax consequences of an investment in the Fund and does not address any foreign, state or local tax consequences.

The Fund intends to meet all requirements under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), necessary to qualify each year for treatment as a “regulated investment company” and thus does not expect to pay any federal income tax on income and capital gains that are timely distributed to shareholders.


ASG Global Alternatives Fund		24		Prospectus – May 1, 2009

FUND SERVICES

Taxation of Distributions from the Fund. For federal income tax purposes, distributions of investment income are generally taxable as ordinary income. Taxes on distributions of capital gains are determined by how long the Fund owned the investments that generated them, rather than how long a shareholder has owned his or her shares. Distributions attributable to the excess of net long-term capital gains from the sale of investments the Fund owned for more than one year over net short-term capital losses and that are designated by the Fund as capital gain dividends (“Capital Gain Dividends”) will generally be taxable to a shareholder receiving such distributions as long-term capital gain. Distributions attributable to the excess of net short-term capital gains from the sale of investments that the Fund owned for one year or less over net long-term capital losses will be taxable as ordinary income.

For taxable years beginning before January 1, 2011, distributions of investment income designated by the Fund as derived from “qualified dividend income” will be taxed in the hands of individuals at the rates applicable to long-term capital gain, provided holding period and other requirements are met at both the shareholder and Fund levels. Income generated by investments in fixed income securities, derivatives and REITs generally is not eligible for treatment as qualified dividend income.

Dividends and distributions declared by the Fund in October, November or December of one year and paid in January of the next year generally are taxable in the year in which the distributions are declared, rather than the year in which the distributions are received.

Dividends derived from interest on securities issued by the U.S. government or its agencies or instrumentalities, if any, may be exempt from state and local income taxes. The Fund will advise shareholders annually of the proportion of the Fund’s dividends that are derived from such interest.

Fund distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder’s investment (and thus were included in the price the shareholder paid for his or her shares). Such distributions are likely to occur in respect of shares purchased at a time when the Fund’s net asset value reflects gains that are either unrealized or realized but not distributed. Fund distributions are taxable whether shareholders receive them in cash or in additional shares.

Distributions by the Fund to retirement plans and other investors that qualify for tax-exempt treatment under federal income tax laws generally will not be taxable.

Redemption, Sale or Exchange of Fund Shares. A redemption, sale or exchange of Fund shares (including an exchange of Fund shares for shares of another Natixis Fund or Money Market Fund) is a taxable event and will generally result in recognition of gain or loss. Gain or loss, if any, recognized by a shareholder on a redemption, sale, exchange or other disposition of Fund shares will generally be treated as long-term capital gain or loss if the shares are capital assets in the shareholder’s hands and the shareholder held the shares for more than one year.

Taxation of Certain Investments. The Fund’s investment in certain debt obligations, mortgage-backed securities, asset-backed securities, REITs and derivatives may cause the Fund to recognize taxable income in excess of the cash generated by such investments. Thus, the Fund could be required to liquidate investments, including at times when it may not be advantageous to do so, in order to satisfy the distribution requirements applicable to regulated investment companies under the Code.

The Fund’s investments in foreign securities may be subject to foreign withholding and other taxes. In that case, the Fund’s yield on those securities would be decreased. The Fund does not expect that shareholders will be entitled to claim a credit or deduction with respect to such foreign taxes incurred by the Fund. In addition, the Fund’s investments in certain foreign securities or in foreign currencies may be subject to special tax rules that have the effect of accelerating or increasing the recognition of income by the Fund, which may in turn affect the timing or amount of the Fund’s distributions to shareholders.


ASG Global Alternatives Fund		25		Prospectus – May 1, 2009

FUND SERVICES

The Fund’s ability to invest directly in commodities and commodities-related investments is limited by the requirement that at least 90 percent of a regulated investment company’s income must consist of certain types of “qualifying income.” Accordingly, the Fund intends to seek exposure to commodities and commodities-related investments by investing in a wholly-owned Cayman Islands subsidiary that would in turn make such investments. The Fund has obtained a private letter ruling from the IRS to the effect that income of the subsidiary that is attributed to the Fund will be qualifying income.

Backup Withholding. The Fund is required in certain circumstances to apply backup withholding on taxable dividends, redemption proceeds and certain other payments that are paid to any shareholder if the shareholder does not furnish to the Fund certain information and certifications or the shareholder is otherwise subject to backup withholding. The backup withholding tax rate is 28% for amounts paid through 2010 and will be 31% for amounts paid after December 31, 2010.

Please see the SAI for additional information on the federal income tax consequences of an investment in the Fund. You should consult your tax adviser for more information on your own situation, including possible federal, state, local, foreign or other applicable taxes.

Evaluating the Fund’s Past Performance


Natixis Equity Funds		2		Prospectus – May 1, 2009

GOALS, STRATEGIES & RISKS

The bar chart shows the Fund’s total returns for Class Y shares for each calendar year since its first full year of operations.

LOGO

The Fund’s Class Y shares total return year-to-date as of March 31, 2009 was -31.81%.

The table below shows how the Fund’s average annual total returns (before and after taxes) for the one-year, five-year and since inception periods compare to those of the MSCI US REIT Index, an unmanaged index of the most actively traded REITs, designed to measure real estate equity performance. You may not invest directly in an index. The Fund’s total returns reflect the expenses of the Fund’s Class Y shares. Class Y total returns have also been calculated to reflect return after taxes on distributions only and also return after taxes on distributions and sales of Fund shares. The MSCI US REIT Index returns have not been adjusted for ongoing management, distribution and operating expenses and sales charges applicable to mutual fund investments.


Average Annual Total Returns (for the periods ended December 31, 2008)	Past 1 Year		Past 5 Years		Since Fund Inception (09/01/00)
AEW Real Estate Fund Class Y – Return Before Taxes	-36.96	%	1.39	%	7.79	%
Return After Taxes on Distributions*	-37.67	%	-0.34	%	5.79	%
Return After Taxes on Distributions & Sales of Fund Shares*	-23.24	%	1.41	%	6.38	%
MSCI US REIT Index**	-37.97	%	0.67	%	7.09	%

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans, qualified plans, education savings accounts, such as 529 plans, or individual retirement accounts. In some cases the after-tax returns may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of fund shares at the end of the measurement period.

**	The returns of the of the index do not reflect a deduction for fees, expenses or taxes.

For information about Fund expenses, see the section “Fund Fees & Expenses.”

CGM Advisor Targeted Equity Fund


Adviser:		Capital Growth Management Limited Partnership (“CGM”)

Manager:		G. Kenneth Heebner

Ticker Symbol:		Class Y
		NEGYX

Investment Goal

The Fund seeks long-term growth of capital through investment in equity securities of companies whose earnings are expected to grow at a faster rate than that of the overall United States economy. The Fund’s investment goal is non-fundamental, which means it may be changed without shareholder approval. The Fund will provide 60 days’ prior written notice to shareholders before changing the investment goal.

Principal Investment Strategies

Under normal market conditions, the Fund will invest at least 80% of its net assets (plus any borrowings made for investment purposes) in equity investments. In accordance with applicable Securities and Exchange Commission (“SEC”) requirements, the Fund will notify shareholders prior to any change to such policy taking effect. The Fund will generally invest in a focused portfolio of common stocks of large capitalization companies that CGM expects will grow at a faster rate than that of the overall United States economy. When CGM believes that market conditions warrant, however, CGM may select stocks based upon overall economic factors, such as the general economic outlook, the level and direction of interest rates and potential impact of inflation. The Fund will not invest in small capitalization companies.

In general, CGM seeks companies with the following characteristics, although not all of the companies selected will have these attributes:

•

Well-established, with records of above-average growth

•

Promise of maintaining their leadership positions in their respective industries

•

Likely to benefit from internal revitalization or innovations, changes in consumer demand or basic economic forces

Rather than following a particular style, CGM employs a flexible approach and seeks to take advantage of opportunities as they arise. In making an investment decision, CGM generally employs the following methods:

•

It uses a top-down approach, meaning that it analyzes the overall economic factors that may affect a potential investment.

•

CGM then conducts a thorough analysis of certain industries and companies, evaluating the fundamentals of each on a case-by-case basis and focusing on companies that it determines are attractively valued.

•

CGM’s ultimate decision to purchase a security results from a thorough assessment of all of the information that CGM deems to be relevant at the time of investment.

•

CGM will sell a stock if it determines that its investment expectations are not being met, if better opportunities are identified or if its price objective has been attained.

The Fund may also:

•

Invest a significant portion of its assets in a single industry sector.

•

Invest in foreign securities, including those in emerging markets.

•

Invest in other investment companies, to the extent permitted by the Investment Company Act of 1940 (the “1940 Act”).

•

Invest in REITs.

GOALS, STRATEGIES & RISKS

•

As a temporary defensive measure, the Fund may hold any portion of its assets in cash (U.S. Dollars, foreign currencies or multinational currency units) and/or invest in money market instruments or high quality debt securities as CGM deems appropriate. The Fund may miss certain investment opportunities if it uses such defensive strategies and thus may not achieve its investment goal.

Principal Investment Risks

Equity securities risk: You may lose money on your investment due to unpredictable drops in a stock’s value or periods of below-average performance in a given stock or in the stock market as a whole. The value of the Fund’s investments in equity securities is subject to the risks of unpredictable declines in the value of individual securities, industries and periods of below-average performance in individual securities, industries or in the equity market as a whole. Growth stocks are generally more sensitive to market movements than other types of stocks primarily because their stock prices are based heavily on future expectations. Growth stocks may underperform value stocks during any given period. Value stocks present the risk that their lower valuations fairly reflect their business prospects or that other investors will not agree that the stocks represent favorable investment opportunities, and they may fall out of favor with investors and underperform growth stocks during any given period. Equity securities may include common stocks, preferred stocks, warrants, securities convertible into common or preferred stocks and other equity-like interests in an entity. Common stocks represent an equity or ownership interest in an issuer. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s bonds and preferred stock take precedence over the claims of those who own common stock. Equity securities may take the form of stock in corporations, limited partnership interests, interests in limited liability companies, REITs or other trusts and other similar securities.

Focused investment risk: Because the Fund may invest in a small number of industries or securities, it may have more risk because the impact of a single economic, political or regulatory occurrence may have a greater adverse impact on the Fund’s net asset value.

Investments in other investment companies risk: The Fund will indirectly bear the management service and other fees of the other investment company in addition to its own expenses.

Management risk: The risk that a strategy used by the Fund’s portfolio managers may fail to produce the intended result.

The table below shows how the Fund’s average annual total returns (before and after taxes) for the one-year, five-year and since inception periods compare to those of the Standard and Poor’s 500 Index (“S&P 500 Index”), an unmanaged index of U.S. common stocks. You may not invest directly in an index. The Fund’s total returns reflect the expenses of the Fund’s Class Y shares. Class Y total returns have also been calculated to reflect return after taxes on distributions only and also return after taxes on distributions and sales of Fund shares. The S&P 500 Index returns have not been adjusted for ongoing management, distribution and operating expenses and sales charges applicable to mutual fund investments.

Evaluating the Fund’s Past Performance

The bar chart and table shown below give an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for the one-year, five-year and ten-year periods compare with those of a broad measure of market performance. The returns shown in the bar chart and table include performance for the Fund’s predecessor, the Reich & Tang Concentrated Portfolio L.P. (the “Predecessor Delafield Fund”), a Delaware limited partnership whose assets and liabilities the Fund acquired in a reorganization that occurred at the close of business on September 26, 2008 (the “Reorganization”). See “Performance Information” in the Fund’s Statement of Additional Information (“SAI”). In the Reorganization, limited partners of the Predecessor Delafield Fund received Class Y shares of the Fund. The Predecessor Delafield Fund was managed using substantially the same investment objectives, policies and restrictions as those used by the Fund. However, the Predecessor Delafield Fund was not registered as an investment company with the SEC. Therefore, it was not subject to the investment restrictions imposed by law on registered mutual funds. If the Predecessor Delafield Fund had been registered, its performance may have been adversely affected. The Fund’s past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

Gateway Fund


Adviser:		Gateway Investment Advisers, LLC (“Gateway”)

Managers:		J. Patrick Rogers, Paul R. Stewart and Michael T. Buckius

Ticker Symbol:		Class Y
		GTEYX

Investment Goal

The Fund seeks to capture the majority of the returns associated with equity market investments, while exposing investors to less risk than other equity investments. The Fund’s investment objective is non-fundamental, which means that it may be changed without shareholder approval. The Fund will provide 60 days’ prior written notice to shareholders before changing the investment goal.

Principal Investment Strategies

Under normal circumstances, the Fund invests in a broadly diversified portfolio of common stocks, while also selling index call options and purchasing index put options. Writing index call options reduces the Fund’s volatility, provides a steady cash flow and is an important source of the Fund’s return, although it also reduces the Fund’s ability to profit from increases in the value of its equity portfolio. The Fund also buys index put options, which can protect the Fund from a significant market decline that may occur over a short period of time. The value of an index put option generally increases as the prices of stocks constituting the index decrease and decreases as those stocks increase in price. The combination of the diversified stock portfolio, the steady cash flow from the sale of index call options and the downside protection from index put options is intended to provide the Fund with the majority of the returns associated with equity market investments while exposing investors to less risk than other equity investments. The Fund may invest in companies with small, medium or large market capitalizations. Equity securities purchased by the Fund may include U.S. exchange-listed common stocks, American Depositary Receipts (“ADRs”), which are securities issued by a U.S. bank that represent interests in foreign equity securities, and interests in REITs.

The Fund not only strives for the majority of the returns associated with equity market investments, but also returns in excess of those available from other investments comparable in volatility. Because, as described above, the Fund writes index call options and purchases index put options in addition to investing in equity securities, the Fund’s historical volatility has been closer to intermediate- to long-term fixed income investments (intermediate-term are those with approximately five-year maturities and long-term are those with maturities of ten or more years) and hybrid investments (blends of equity and short-term fixed income securities) than to equity investments. With its core investment in equities, the Fund is significantly less vulnerable to fluctuations in value caused by interest rate volatility, a risk factor present in both fixed income and hybrid investments, although the Fund expects to generally have lower long-term returns than a Fund consisting solely of equity securities. The Fund intends that its index option-based risk management strategy will reduce the volatility inherent in equities while sacrificing less of the higher equity returns than hybrid investments. Thus, the Fund seeks to provide an efficient trade-off between risk and reward where risk is characterized by volatility or fluctuations in value over time.

The Fund’s investment strategies are described in more detail below:

•

The Fund invests in a diversified stock portfolio, generally consisting of approximately 200 to 400 stocks, designed to support the Fund’s index option-based risk management strategy as efficiently as possible while seeking to enhance the Fund’s total return. Gateway uses a multi-factor quantitative model to construct the stock portfolio. The model evaluates approximately 9,000 equity securities to construct a portfolio of US-exchange-traded equities that meets criteria and constrains established by the Adviser. Generally, Gateway tries to minimize the difference between the performance of the stock portfolio and that of the index or indexes underlying the Fund’s option strategies while also


Natixis Equity Funds		11		Prospectus – May 1, 2009

GOALS, STRATEGIES & RISKS

considering other factors, such as predicted dividend yield. Gateway monitors this difference and the other factors, and rebalances and adjusts the stock portfolio from time to time, by purchasing and selling stocks. Gateway expects the portfolio to generally represent the broad U.S. equity market.

•

The Fund continuously writes index call options, typically on broad-based securities market indices, on the full value of its broadly diversified stock portfolio. As the seller of the index call option, the Fund receives cash (the “premium”) from the purchaser. The purchaser of an index call option has the right to any appreciation in the value of the index over a fixed price (the “exercise price”) on a certain date in the future (the “expiration date”). If the purchaser does not exercise the option, the Fund retains the premium. If the purchaser exercises the option, the Fund pays the purchaser the difference between the value of the index and the exercise price of the option. The premium, the exercise price and the value of the index determine the gain or loss realized by the Fund as the seller of the index call option. The Fund can also repurchase the call option prior to the expiration date, ending its obligation. In this case, the difference between the cost of repurchasing the option and the premium received will determine the gain or loss realized by the Fund.

•

The Fund may buy index put options in an attempt to protect the Fund from a significant market decline that may occur over a short period of time. The value of an index put option generally increases as stock prices (and the value of the index) decrease and decreases as those stocks (and the index) increase in price. The Fund may not spend at any time more than 5% of its assets to purchase index put options.

•

The Fund may invest in foreign securities traded in U.S. markets (through ADRs or stocks traded in U.S. dollars). The Fund may also invest in other investment companies, including money market funds, to the extent permitted by the 1940 Act. The Fund may enter into repurchase agreements and/or hold cash and cash equivalents.

As a temporary defensive measure, the Fund may purchase U.S. government securities, certificates of deposit, commercial paper, bankers’ acceptance, and/or repurchase agreements or hold cash (U.S. Dollars, foreign currencies or multinational currency units) for temporary defensive purposes in response to adverse market, economic or political conditions, or, under normal circumstances, for purposes of liquidity. These investments may prevent the Fund from achieving its investment objective.

Principal Investment Risks

Correlation risk: The effectiveness of the Fund’s index option-based risk management strategy may be reduced if the Fund’s equity portfolio does not correlate to the index underlying its option positions.

Equity securities risk: You may lose money on your investment due to unpredictable drops in the value of a security or periods of below-average performance in a given stock or the stock market as a whole. The value of the Fund’s investments in equity securities is subject to the risks of unpredictable declines in the value of individual securities and periods of below-average performance in individual securities or in the equity market as a whole. Small capitalization and emerging growth companies may be subject to more abrupt price movements, limited markets and less liquidity than larger, more established companies which could adversely effect the value of the Fund’s portfolio. Growth stocks are generally more sensitive to market movements than other types of stocks primarily because their stock prices are based heavily on future expectations. Growth stocks may underperform value stocks during any given period. Value stocks present the risk that their lower valuations fairly reflect their business prospects or that other investors will not agree that the stocks represent favorable investment opportunities, and they may fall out of favor with investors and underperform growth stocks during any given period. Equity securities may include common stocks, preferred stocks, warrants, securities convertible into common or preferred stocks and other equity-like interests in an entity. Common stocks represent an equity or ownership interest in an issuer. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s bonds and preferred stock take precedence over the claims of those who own common stock. Equity securities may take the form of stock in corporations, limited partnership interests, interests in limited liability companies, REITs or other trusts and other similar securities.


Natixis Equity Funds		12		Prospectus – May 1, 2009

GOALS, STRATEGIES & RISKS

Foreign securities risk: The Fund may invest in foreign securities traded in U.S. markets, including through ADRs. Foreign securities are subject to foreign currency fluctuations, higher volatility than U.S. securities and limited liquidity. Political, economic and information risks are also associated with foreign securities. Investments in emerging markets may be subject to these risks to a greater extent than those in more developed markets. The Fund’s investments in foreign securities may be subject to foreign withholding and other taxes. In that case, the Fund’s yield on those securities would be decreased. Settlement practices for transactions in foreign markets may differ from those in U.S. markets. Such differences include delays beyond periods customary in the U.S. and practices, such as delivery of securities prior to receipt of payment, which increase the likelihood of a “failed settlement.” Failed settlements can result in losses to the Fund. Investments in emerging markets may be subject to these risks to a greater extent than those in more developed markets.

Management risk: The risk that a strategy used by the Fund’s portfolio managers may fail to produce the intended result.

Options risk: The value of the Fund’s positions in index options fluctuates in response to changes in the value of the underlying index. Writing index call options reduces the risk of owning stocks, but it limits the opportunity to profit from an increase in the market value of stocks in exchange for up-front cash at the time of selling the call option. The Fund also risks losing all or part of the cash paid for purchasing index put options. Unusual market conditions or the lack of a ready market for any particular option at a specific time may reduce the effectiveness of the Fund’s option strategies, and for these and other reasons the Fund’s option strategies may not reduce the Fund’s volatility to the extent desired. From time to time, the Fund may reduce its holdings of put options, resulting in an increased exposure to a market decline.

Shareholders of the Predecessor Fund received Class A shares of the Fund, which are offered in a separate prospectus. The Fund’s class Y shares were not outstanding prior to the Reorganization. Although the Predecessor Fund’s shares and the Fund’s Class Y shares would have had substantially similar annual returns because the shares would have been invested in the same portfolio of securities, returns for Class Y would have been different to the extent their respective expenses differ. Performance for periods after the Reorganization reflect actual Class Y performance.

Evaluating the Fund’s Past Performance

Because the Fund did not have Class Y shares outstanding during the periods shown, the returns shown in the bar chart and average annual total returns table below are those of the Fund’s Class A shares, which are not offered through this prospectus. The bar chart shows the Fund’s total returns for Class A shares for each of the last ten calendar years. Class Y shares would have had substantially similar returns because they were invested in the same portfolio of securities as Class A shares and would only differ to the extent the classes did not have the same expenses. The Class Y returns may be higher than the returns of Class A shares because Class A shares are subject to sales charges and higher expenses.

The bar chart shows the Fund’s total returns for Class Y shares for each of the last ten calendar years.

LOGO

The table below shows how the Fund’s average annual total returns (before and after taxes) for the one-year, five-year and ten-year periods compare to those of the Russell 1000 Value Index, an unmanaged index measuring the performance of those Russell 1000 companies with lower price-to-book ratios and lower forecasted growth values. You may not invest directly in an index. The Fund’s total returns reflect the expenses of the Fund’s Class Y shares. Class Y total returns have also been calculated to reflect return after taxes on distributions only and also return after taxes on distributions and sales of Fund shares. The Russell 1000 Value Index returns have not been adjusted for ongoing management, distribution and operating expenses applicable to mutual fund investments.


Average Annual Total Returns (for the periods ended December 31, 2008)	Past 1 Year		Past 5 Years		Past 10 Years
Harris Associates Large Cap Value Fund Class Y – Return Before Taxes	-40.18	%	-5.68	%	-3.65	%
Return After Taxes on Distributions*	-40.37	%	-5.77	%	-4.23	%
Return After Taxes on Distributions & Sales of Fund Shares*	-25.87	%	-4.72	%	-3.14	%
Russell 1000 Value Index**	-36.85	%	-0.79	%	1.36	%

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans, qualified plans, education savings accounts, such as 529 plans, or individual retirement accounts. In some cases the after-tax returns may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of fund shares at the end of the measurement period.

**	The returns of the index do not reflect a deduction for fees, expenses or taxes.

Vaughan Nelson Small Cap Value Fund


Adviser:		Natixis Asset Management Advisors, L.P. (“Natixis Advisors”)

Subadviser:		Vaughan Nelson Investment Management, L.P. (“Vaughan Nelson”)

Managers:		Chris D. Wallis and Scott J. Weber

Ticker Symbol:		Class Y
		NEJYX

Investment Goal

The Fund seeks capital appreciation. The Fund’s investment goal is non-fundamental, which means it may be changed without shareholder approval. The Fund will provide 60 days’ prior written notice to shareholders before changing the investment goal.

Principal Investment Strategies

The Fund, under normal market conditions, will invest at least 80% of its net assets (plus any borrowings made for investment purposes) in companies that, at the time of purchase, have market capitalizations within the capitalization range of the Russell 2000 Value Index, an unmanaged index that measures the performance of those Russell 3000 companies with lower price-to-book ratios and lower forecasted growth value. In accordance with applicable SEC requirements, the Fund will notify shareholders prior to any change to such policy taking effect. The Fund may, however, invest in companies with larger capitalizations.

•

Companies earning a positive economic margin with stable-to-improving returns.

•

Companies valued at a discount to their asset value.

•

Companies with an attractive and sustainable dividend level.

In selecting investments for the Fund, Vaughan Nelson generally employs the following strategy:

•

Vaughan Nelson uses fundamental analysis to construct a portfolio of 60 to 80 securities consisting of quality companies in the opinion of Vaughan Nelson.

•

The Fund may also:

•

Invest in convertible preferred stock and convertible debt securities.

•

Invest up to 35% of its assets in fixed-income securities, including U.S. government bonds as well as lower quality debt securities.

•

Invest in foreign securities, including those of emerging markets.

•

Invest in REITs.


Natixis Equity Funds		28		Prospectus – May 1, 2009

GOALS, STRATEGIES & RISKS

•

Invest in securities offered in initial public offerings (“IPOs”).

•

As a temporary defensive measure, the Fund may hold any portion of its assets in cash (U.S. Dollars, foreign currencies or multinational currency units) and/or invest in money market instruments or high quality debt securities as Vaughan Nelson deems appropriate. The Fund may miss certain investment opportunities if it uses such defensive strategies and thus may not achieve its investment goal.

Principal Investment Risks

Equity securities risk: You may lose money on your investment due to unpredictable drops in a stock’s value or periods of below-average performance in a given stock or in the stock market as a whole. The value of the Fund’s investments in equity securities is subject to the risks of unpredictable declines in the value of individual securities, industries and periods of below-average performance in individual securities, industries or in the equity market as a whole. Securities issued in IPOs tend to involve greater market risk than other equity securities due, in part, to public perception and the lack of publicly available information and trading history. Value stocks present the risk that their lower valuations fairly reflect their business prospects or that other investors will not agree that the stocks represent favorable investment opportunities, and they may fall out of favor with investors and underperform growth stocks during any given period. Equity securities may include common stocks, preferred stocks, warrants, securities convertible into common or preferred stocks and other equity-like interests in an entity. Common stocks represent an equity or ownership interest in an issuer. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s bonds and preferred stock take precedence over the claims of those who own common stock. Equity securities may take the form of stock in corporations, limited partnership interests, interests in limited liability companies, REITs or other trusts and other similar securities.

Management risk: The risk that a strategy used by the Fund’s portfolio managers may fail to produce the intended result.

Evaluating the Fund’s Past Performance

The bar chart and table shown below give an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year by showing how the Fund’s average annual returns for the one-year and since inception periods compare with those of a broad measure of market performance. The Fund’s past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

LOGO

The table below shows how the Fund’s average annual total returns (before and after taxes) for the one-year and since inception periods compare to those of the Russell 2000 Value Index, an unmanaged index measuring the performance of those Russell 2000 companies with lower price-to-book ratios and lower forecasted growth values. You may not invest directly in an index. The Fund’s total returns reflect its expenses and the maximum sales charge that you may be required to pay when you buy or redeem the Fund’s shares. Class Y total returns have also been calculated to reflect returns after taxes on distributions only and also returns after taxes on distributions and sales of Fund shares. The Russell 2000 Value Index returns have not been adjusted for ongoing management, distribution and operating expenses applicable to mutual fund investments.

A discussion of the factors considered by the Funds’ Board of Trustees in approving the Funds’ investment advisory and sub-advisory contracts is available in the Funds’ financial reports for the six months ended June 30, 2008 for the CGM Advisor Targeted Equity Fund, Gateway Fund, Hansberger International Fund, Harris Associates Large Cap Value Fund, Natixis U.S. Diversified Portfolio and Vaughan Nelson Small Cap Value Fund, for the six months ended July 31, 2008 for the AEW Real Estate Fund and for the twelve months ended December 31, 2008 for the Delafield Select Fund and the Vaughan Nelson Value Opportunity Fund.

Portfolio Trades

Securities Lending. Each Fund (except Gateway Fund) may lend a portion of its portfolio securities to brokers, dealers and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. Please see “Investment Strategies” in the SAI for details. When a Fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the Fund will also receive a fee or interest on the collateral. Securities lending involves the risk of loss of rights in the collateral or delay in recovery of the collateral if the borrower fails to return the security loaned or becomes insolvent. A Fund may pay lending fees to the party arranging the loan.

Transactions with Other Investment Companies. Pursuant to SEC exemptive relief, each Fund (except CGM Advisor Targeted Equity Fund) may be permitted to invest its daily cash balances in shares of money market and short-term bond funds advised by Natixis Advisors or its affiliates (“Central Funds”). The Central Funds currently include two money market funds: the Money Market Fund and the Daily Income Fund. The Money Market Fund is advised by Natixis Advisors and subadvised by Reich & Tang and the Daily Income Fund is advised by Reich & Tang. Because Natixis Advisors and Reich & Tang are each subsidiaries of Natixis US, the Fund and the Central Funds may be considered to be related companies comprising a “group of investment companies” under the 1940 Act. The Funds may also make investments in related investment companies to the extent permitted by SEC regulation.


Natixis Equity Funds		42		Prospectus – May 1, 2009

MANAGEMENT TEAM

because the Funds, and other funds, are advised by firms that are affiliated with one another, they may be considered to be related companies comprising a “group of investment companies” under the 1940 Act. The Central Funds will participate in the credit facility only as lenders. Participation in such an interfund lending program would be voluntary for both borrowing and lending funds, and a Fund would participate in an interfund lending program only if the Board of Trustees determined that doing so would benefit the Fund. Should a Fund participate in such an interfund lending program, the Board of Trustees would establish procedures for the operation of the program by the advisers or an affiliate. The Funds may engage in the transactions described above without further notice to shareholders. The Funds may also make investments in related investment companies to the extent permitted by SEC regulation.

Investing in the Funds

Compensation to Securities Dealers

The Distributor, the Funds’ advisers and their respective affiliates will, out of their own resources, which generally come directly or indirectly from fees paid by the Funds, make payments to certain dealers and other financial intermediaries that satisfy certain criteria established from time to time by the Distributor. Payments may vary based on sales, the amount of assets a dealer’s or intermediary’s clients have invested in the Funds, and other factors. These payments may also take the form of sponsorship of seminars or informational meetings or payments for attendance by persons associated with a dealer or intermediary at informational meetings. The Distributor and its affiliates may also make payments for recordkeeping and other transfer agency-related services to dealers and intermediaries that sell Fund shares.

The payments described in this section, which may be significant to the dealers and the financial intermediaries, may create an incentive for a dealer or financial intermediary or their representatives to recommend or sell shares of a particular fund or share class over other mutual funds or share classes. Additionally, these payments may result in the Funds receiving certain marketing or servicing advantages that are not generally available to mutual funds that do not make such payments, including placement on a sales list, including a preferred or select sales list, or in other sales programs. These payments may create potential conflicts of interest between an investor and a dealer or other financial intermediary who is recommending a particular mutual fund over other mutual funds. Before investing, you should consult with your financial representative and review carefully any disclosure by the dealer or other financial intermediary as to what monies it receives from mutual fund advisers and distributors, as well as how your financial representative is compensated. Please see the SAI for additional information about payments made by the Distributor and its affiliates to dealers and intermediaries. Please also contact your dealer or financial intermediary for details about payments it may receive.

The exchange privilege may be exercised only in those states where shares of such funds may be legally sold.

Subject to the applicable rules of the SEC, the Board of Trustees reserves the right to modify the exchange privilege at any time. Before requesting an exchange into any other fund, please read its prospectus carefully. You may be unable to hold your shares through the same financial intermediary if you engage in certain share exchanges. You should contact your financial intermediary for further details. Please refer to the SAI for more detailed information on exchanging Fund shares.

Restrictions on Buying, Selling and Exchanging Shares

The Funds discourage excessive, short-term trading that may be detrimental to the Funds and their shareholders. Frequent purchases and redemptions of Fund shares by shareholders may present certain risks for other shareholders in a Fund. This includes the risk of diluting the value of Fund shares held by long-term shareholders, interfering with the efficient management of the Fund’s portfolio, and increasing brokerage and administrative costs. Funds investing in securities that require special valuation processes (such as foreign securities, high yield securities, or small cap securities) may also have increased exposure to these risks. The Funds’ Board of Trustees has adopted the following policies to address and discourage such trading.


Natixis Equity Funds		50		Prospectus – May 1, 2009

FUND SERVICES

Notwithstanding the above, certain financial intermediaries, such as retirement plan administrators, may monitor and restrict the frequency of purchase and redemption transactions in a manner different from that described above. The policies of these intermediaries may be more or less restrictive than the generally applicable policies described above. The Fund may choose to rely on a financial intermediary’s restrictions on frequent trading in place of the Fund’s own restrictions if the Fund determines, in its discretion, that the financial intermediary’s restrictions provide reasonable protection for the Fund from excessive short-term trading activity. Please contact your financial representative for additional information regarding their policies for limiting the frequent trading of Fund shares.

Trade Activity Monitoring. Trading activity is monitored selectively on a daily basis in an effort to detect excessive short-term trading activities. If the Fund or the Distributor believes that a shareholder or financial intermediary has engaged in market timing or other excessive, short-term trading activity, it may, in its discretion, request that the shareholder or financial intermediary stop such activities or refuse to process purchases or exchanges in the accounts. In its discretion, the Fund or the Distributor may restrict or prohibit transactions by such identified shareholders or intermediaries. In making such judgments, the Fund and the Distributor seek to act in a manner that they believe is consistent with the best interests of all shareholders. The Fund and the Distributor also reserve the right to notify financial intermediaries of the shareholder’s trading activity.

Accounts Held by Financial Intermediaries. The ability of a Fund and the Distributor to monitor trades that are placed by omnibus or other nominee accounts is more limited in those instances in which the financial intermediary maintains the record of a Fund’s underlying beneficial owners. In general, each Fund and the Distributor will review trading activity at the omnibus account level. If a Fund and the Distributor detect suspicious activity, they may request and receive personal identifying information and transaction histories for some or all underlying shareholders (including plan participants) to determine whether such shareholders have engaged in market timing or other excessive, short-term trading activity. If a Fund believes that a shareholder has engaged in market timing or other excessive, short-term trading activity in violation of the Fund’s policies through an omnibus account, the Fund will attempt to limit transactions by the underlying shareholder which engaged in such trading, although it may be unable to do so. The Fund may also limit or prohibit additional purchases of Fund shares by an intermediary. Investors should not assume the Fund will be able to detect or prevent all market timing or other trading practices that may disadvantage the Fund.

How Fund Shares Are Priced

“Net asset value” is the price of one share of a Fund without a sales charge, and is calculated each business day using this formula:


Net Asset Value =		Total market value of securities + Cash and other assets – Liabilities
Net Asset Value =		Number of outstanding shares

The net asset value of Fund shares is determined pursuant to policies and procedures approved by the Board of Trustees, as summarized below:

•

A fund that invests in foreign securities may have net asset value changes on days when you cannot buy or sell its shares.

1	Please see the section “Buying Shares”, which provides additional information regarding who can receive a purchase order.

Generally, Fund securities are valued as follows:

•

Equity securities — last sale price on the exchange or market where primarily traded or, if there is no reported sale during the day, the closing bid price.

•

Short-term obligations (purchased with an original or remaining maturity of 60 days or less) — amortized cost (which approximates market value).

•

Options — domestic exchange-traded single equity option contracts are valued a the mean of the National Best Bid and offer quotations. Exchange-traded index options and foreign exchange-traded single equity options are valued at the average of the closing big and asked quotations. Under normal market conditions, the Fund will generally consider


Natixis Equity Funds		53		Prospectus – May 1, 2009

FUND SERVICES

the value of domestic exchange-traded index options determined at the close of trading on the Chicago Board Options Exchange (the “CBOE”) (normally 4:15 p.m., Eastern time) to be the value at the close of the NYSE (normally 4:00 p.m., Eastern time). However, if under the Fund’s valuation procedures a significant change in the value of the S&P 500 contracts is considered to have occurred between the close of the NYSE and the close of the CBOE, the Fund will consider the closing price on the CBOE to not reflect the value of the index options at the close of the NYSE. In such circumstances the options will be fair valued by or pursuant to procedures approved by the Board of Trustees. On the last business day of the month, Gateway Fund will fair value index options using the closing rotation values as published by the CBOE.

•

Futures — current settlement price.

•

Forward foreign currency contracts — interpolated prices determined based on information provided by an independent pricing service.

•

All other securities — fair market value as determined by the adviser or subadviser of the Fund pursuant to procedures approved by the Board of Trustees.

Tax Consequences

Except as noted, the discussion below addresses only the U.S. federal income tax consequences of an investment in the Fund and does not address any non-U.S., state or local tax consequences.

Each Fund intends to meet all requirements under Subchapter M of the Internal Revenue Code (the “Code”), necessary to qualify each year for treatment as a “regulated investment company” and thus does not expect to pay any federal income tax on income and capital gains that are timely distributed to shareholders. Even though the Delafield Select Fund is not diversified for purposes of the 1940 Act, the Fund still intends to be diversified for purposes of meeting the requirements of Subchapter M.

Taxation of Distributions from the Fund. For federal income tax purposes, distributions of investment income generally are taxable to Fund shareholders as ordinary income. Taxes on distributions of capital gains are determined by how long a Fund owned the investments that generated them, rather than how long a shareholder has owned his or her shares. Distributions attributable to the excess of net long-term capital gains from the sale of investments a Fund owned for more than one year over net short-term capital losses and that are properly designated by the Fund as capital gain dividends (“Capital Gain Dividends”) will generally be taxable to a shareholder receiving such distributions as long-term capital gain. Distributions attributable to the excess of nest short-term capital gains from the sale of investments that a Fund owned for one year or less over net long-term capital losses will be taxable as ordinary income.

Fund distributions are taxable whether shareholders receive them in cash in additional shares. In addition, Fund distributions are taxable to shareholders even if they are paid from income or gains earned by a Fund before a shareholder’s investment (and thus were included in the price the shareholder paid for his or her shares). Such distributions are likely to occur in respect of shares purchased at a time when a Fund’s net asset value reflects gains that are either unrealized or realized but not distributed. Distributions by a Fund to retirement plans that qualify for tax-exempt treatment under federal income tax laws generally will not be taxable.

Redemption, Sale or Exchange of Fund Shares. A redemption, sale or exchange of Fund shares (including an exchange of Fund shares for shares of another Natixis Fund or Loomis Sayles Fund) is a taxable event and will generally result in recognition of gain or loss. Gain or loss, if any, recognized by a shareholder on a redemption, sale, exchange or other disposition of Fund shares generally will be taxed as long-term capital gain or loss if the shares are capital assets in the shareholder’s hands and if the shareholder held the shares for more than one year.

Taxation of Certain Fund Investments. A Fund’s investments in foreign securities may be subject to foreign withholding and other taxes. In that case, the Fund’s yield on those securities would be decreased. Shareholders generally will not be entitled to claim a credit or deduction with respect to foreign taxes incurred by a Fund, except that of a Fund investing more than 50% of its assets in foreign securities, such as the Hansberger International Fund, may elect to permit shareholders claim a credit or deduction for their respective pro rata shares of qualifying foreign taxes paid by or withheld from amounts paid to the Fund. In such a case, shareholders will be required to include in gross income from foreign sources their pro rata

FUND SERVICES

shares of such taxes, and each shareholder’s ability to claim a foreign tax credit or deduction for such foreign taxes will be subject to generally applicable limitations imposed by the Code, which may result in the shareholder not getting a full credit or deduction for the amount of such taxes.

In addition, a Fund’s investments in foreign securities or foreign currencies may be subject to special tax rules that have the effect of increasing or accelerating the Fund’s recognition of ordinary income and may affect the timing or amount of the Fund’s distributions.

A Fund’s investments in certain debt obligations, derivatives or REITs may cause that Fund to recognize taxable income in excess of the cash generated by such instruments. Thus, a Fund could be required to liquidate investments, including at times when it is not advantageous to do so, in order to satisfy its distribution requirements.

In addition, a Fund’s investments in other investment companies could affect the amount, timing, and character of distributions from the Funds, and, therefore, may increase the amount of taxes payable by shareholders.

Backup Withholding. Each Fund is required in certain circumstances to apply backup withholding on taxable dividends, redemption proceeds and certain other payments that are paid to any shareholder if the shareholder does not furnish to the Fund certain information and certifications or the shareholder is otherwise subject to backup withholding. The backup withholding tax rate is 28% for amounts paid on or before December 31, 2010 and will be 31% for amounts paid after December 31, 2010.

Please see the SAI for additional information on the federal income tax consequences of an investment in a Fund.

You should consult your tax adviser for more information on your own situation, including possible federal, state, local, foreign or other applicable taxes.

Principal Investment Risks

The principal risks of investing in the Fund are described below. There are other circumstances (including non-principal risks that are not described here) which could prevent the Fund from achieving its investment goals. The Fund does not represent a complete investment program. The Fund’s net asset value may fluctuate substantially over time. You may lose money by investing in the Fund.


ASG Global Alternatives Fund		2		Prospectus – May 1, 2009

GOALS, STRATEGIES & RISKS

Currency risk: This is the risk that fluctuations in exchange rates between the U.S. dollar and foreign currencies may cause the value of the Fund’s investments to decline.

Foreign securities risk: This is the risk associated with investments in issuers located in foreign countries. The Fund’s investments in foreign securities may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. The securities markets of many foreign countries are relatively small, with a limited number of issuers and a small number of securities. In addition, foreign companies often are not subject to the same degree of regulation as U.S. companies. Reporting, accounting and auditing standards of foreign countries differ, in some cases significantly, from U.S. standards. Nationalization, expropriation or confiscatory taxation, currency blockage, political changes or diplomatic developments can cause the value of the Fund’s non-U.S. investments to decline. In the event of nationalization, expropriation or other confiscation, the Fund could lose its entire foreign investment. Investments in emerging markets may be subject to these risks to a greater extent than those in more developed markets.

Valuation risk: The risk that the Fund has valued certain securities at a higher price than the price at which they can be sold or, for short positions, at a lower price than the price at which they can be purchased.

For additional information, see the section “More About Risk.”

Evaluating the Fund’s Past Performance

Example

This example**, which is based upon the expenses shown in the “Annual Fund Operating Expenses” table, is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

You invest $10,000 in the Fund for the time periods indicated;

•

Your investment has a 5% return each year;

•

The Fund’s operating expenses remain the same; and

•

All dividends and distributions are reinvested.

Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

	Class Y
1 year	$	141
3 years	$	687

1	Includes an estimate of 0.12% of management fees borne by the Fund through investments made through the Commodity Subsidiary.

2	“Other expenses” are based on estimated amounts for the current fiscal year. “Other expenses” include 0.38% of estimated expenses borne by the Fund through investments made through the Commodity Subsidiary and 0.04% of estimated interest expense.


ASG Global Alternatives Fund		6		Prospectus – May 1, 2009

FUND FEES & EXPENSES

The Adviser has given a binding contractual undertaking to the Fund to limit the amount of the Fund’s total annual fund operating expenses, exclusive of brokerage expenses, expenses estimated to be indirectly borne by the Fund through investments in certain pooled investment vehicles (“Acquired Fund Fees and Expenses”), interest expense, taxes and extraordinary expenses, such as litigation and indemnification expenses, to 1.35% of the Fund’s average daily net assets for Class Y shares. This undertaking is in effect through April 30, 2010 and may be terminated only with the consent of the Fund’s Board of Trustees; however, the Board of Trustees does not intend to terminate this undertaking. The Fund’s Adviser will be permitted to recover, on a class by class basis, management fees reduced and/or expenses reimbursed it has borne through the undertakings described in this footnote to the extent that Class Y’s expenses in later periods fall below the annual rates set forth in the relevant undertaking. The Adviser may not recover any such reduced fees and expenses with respect to a class more than one year after the end of the fiscal year in which the fee/expense was deferred. Without this undertaking, expenses would be higher.

*	Generally, a transaction fee will be charged for expedited payment of redemption proceeds of $5.50 for wire transfers or $20.50 for overnight delivery. These fees are subject to change.

**	The example is based on the estimated Net Expenses for the first year illustrated in the example and on the estimated Total Annual Fund Operating Expenses for the remaining periods.

Exchanging Shares

Restrictions on Buying, Selling and Exchanging Shares

Limits on Frequent Trading. Without limiting the right of the Fund and the Distributor to reject any purchase or exchange order, the Fund and the Distributor may (but are not obligated to) restrict purchases and exchanges for the accounts of “market timers.” An account may be deemed to be one of a market timer if it makes two “round trips” in the Fund over a 90-day interval, as determined by the Fund. A “round trip” is a purchase (including a purchase by exchange) into the Fund


ASG Global Alternatives Fund		15		Prospectus – May 1, 2009

FUND SERVICES

followed by a redemption (including a redemption by exchange) of any amount out of the Fund. The above limits are applicable whether you hold shares directly with the Fund or indirectly through a financial intermediary, such as a broker, bank, investment adviser, recordkeeper for retirement plan participants, or other third party. The preceding is not an exclusive description of activities that the Fund and the Distributor may consider to be “market timing.” Notwithstanding the above, certain financial intermediaries, such as retirement plan administrators, may monitor and restrict the frequency of purchase and redemption transactions in a manner different from that described above. The policies of these intermediaries may be more or less restrictive than the generally applicable policies described above. The Fund may choose to rely on a financial intermediary’s restrictions on frequent trading in place of the Fund’s own restrictions if the Fund determines, in its discretion, that the financial intermediary’s restrictions provide reasonable protection for the Fund from excessive short-term trading activity. Please contact your financial representative for additional information regarding their policies for limiting the frequent trading of Fund shares.

This policy also does not apply with respect to shares purchased by certain funds-of-funds or similar asset allocation programs that rebalance their investments only infrequently. To be eligible for this exemption, the fund-of-funds or asset allocation program must identify itself to and receive prior written approval from the Fund or the Distributor. The Fund and Distributor may request additional information to enable them to determine that the fund-of-funds or asset allocation program is not designed to and/or is not serving as a vehicle for disruptive short-term trading, which may include requests for (i) written assurances from the sponsor or investment manager of the fund-of-funds or asset allocation program that it enforces the Fund’s frequent trading policy on investors or another policy reasonably designed to deter disruptive short-term trading in Fund shares, and/or (ii) data regarding transactions by investors in the fund-of-funds or asset allocation program, for periods and on a frequency determined by the Fund and Distributor, so that the Fund can monitor compliance by such investors with the trading limitations of the Fund or of the fund-of-funds or asset allocation program.

Accounts Held by Financial Intermediaries. The ability of the Fund and the Distributor to monitor trades that are placed by omnibus or other nominee accounts is more limited in those instances in which the financial intermediary maintains the record of a Fund’s underlying beneficial owners. In general, the Fund and the Distributor will review trading activity at the omnibus account level. If the Fund and the Distributor detect suspicious activity, they may request and receive personal identifying information and transaction histories for some or all underlying shareholders (including plan participants) to determine whether such shareholders have engaged in market timing or other excessive, short-term trading activity. If the Fund believes that a shareholder has engaged in market timing or other excessive, short-term trading activity in violation of the Fund’s policies through an omnibus account, the Fund will attempt to limit transactions by the underlying shareholder which engaged in such trading, although it may be unable to do so. The Fund may also limit or prohibit additional purchases of Fund shares by an intermediary. Investors should not assume the Fund will be able to detect or prevent all market timing or other trading practices that may disadvantage the Fund.

Purchase Restrictions


ASG Global Alternatives Fund		16		Prospectus – May 1, 2009

FUND SERVICES

Selling Restrictions

The table below describes restrictions placed on selling shares of the Fund. Please see the SAI for additional information regarding redemption payment policies:


Restriction		Situation

The Fund may suspend the right of redemption or postpone payment for more than 7 days:		• When the New York Stock Exchange (the “NYSE”) is closed (other than a weekend/holiday) as permitted by the SEC.
		• During an emergency as permitted by the SEC.
		• During any other period permitted by the SEC.

The Fund reserves the right to suspend account services or refuse transaction requests:		• With a notice of a dispute between registered owners or death of a registered owner.
		• With suspicion/evidence of a fraudulent act.

The Fund may pay the redemption price in whole or in part by a distribution in kind of readily marketable securities in lieu of cash or may take up to 7 days to pay a redemption request in order to raise capital:		• When it is detrimental for the Fund to make cash payments as determined in the sole discretion of the adviser or subadviser.

The Fund may withhold redemption proceeds for 10 days from the purchase date:		• When redemptions are made within 10 calendar days of purchase by check or ACH to allow the check or ACH transaction to clear.

How Fund Shares Are Priced

“Net asset value” is the price of one share of the Fund without a sales charge, and is calculated each business day using this formula:


Net Asset Value =		Total market value of securities + Cash and other assets – Liabilities
		Number of outstanding shares

The net asset value of Fund shares is determined pursuant to policies and procedures approved by the Board of Trustees, as summarized below:

•


ASG Global Alternatives Fund		17		Prospectus – May 1, 2009

FUND SERVICES

the Fund determines its net asset value (normally 4:00 p.m., Eastern time) are processed at the net asset value determined on the day the order was received by your investment dealer. Please contact your investment dealer to determine whether it has entered into such a contractual agreement. If your investment dealer has not entered into such a contractual agreement, your order will be processed at the net asset value next determined after your investment dealer submits the order to the Fund.

•

A fund that invests in foreign securities may have net asset value changes on days when you cannot buy or sell its shares.

1 Please see the section “Buying Shares”, which provides additional information regarding who can receive a purchase order.

•

Equity securities — last sale price on the exchange or market where primarily traded or, if there is no reported sale during the day, the closing bid price.

•

Short-term obligations (purchased with an original or remaining maturity of 60 days or less) — amortized cost (which approximates market value).

•

Securities traded on foreign exchanges — market price on the foreign exchange, unless the Fund believes that an occurrence after the close of that exchange will materially affect the security’s value. In that case, the security may be fair valued at the time the Fund determines its net asset value by or pursuant to procedures approved by the Board of Trustees. When fair valuing their securities, the Fund may, among other things, use modeling tools or other processes that may take into account factors such as securities market activity and/or significant events that occur after the close of the local market and before the time the Fund’s net asset value is calculated.

•

Futures — current settlement price.

•

Foreign Currency Forward Contracts — interpolated prices determined based on information provided by an independent pricing service.

•

All other securities — fair market value as determined by the adviser or subadviser of the Fund pursuant to procedures approved by the Board of Trustees.

As described above, if market prices are not readily available for a security, securities may not be priced on the basis of quotations from the primary market in which they are traded but rather may be priced by another method that the Board of Trustees believes is more likely to result in a price that reflects fair value (which is the amount that the Fund might reasonably expect to receive from a current sale of the security in the ordinary course of business). The Fund may also value securities at fair value or estimate their value pursuant to procedures approved by the Board of Trustees in other circumstances such as when extraordinary events occur after the close of the relevant market but prior to the close of the NYSE. This may include situations relating to a single issuer (such as a declaration of bankruptcy or a delisting of the issuer’s security from the primary market on which it has traded) as well as events affecting the securities markets in general (such as market disruptions or closings and significant fluctuations in U.S. and/or foreign markets). Fair value pricing may require subjective determinations about the value of a security, and fair values used to determine the Fund’s net asset value may differ from quoted or published prices, or from prices that are used by others, for the same securities. In addition, the use of fair value pricing may not always result in adjustments to the prices of securities held by the Fund.

Dividends and Distributions

Distributions will automatically be reinvested in shares of the same class of the distributing Fund at net asset value, unless you select one of the following alternatives:

•

Receive distributions from dividends and interest in cash while reinvesting distributions from capital gains in additional Class Y shares of the Fund, or Class Y shares of another Natixis Fund.

•

Receive all distributions in cash.

For more information or to change your distribution option, contact Natixis Funds in writing or call 800-225-5478.

If you earn more than $10 annually in taxable income from a Natixis Fund held in a non-retirement plan account, you will receive a Form 1099 to help you report the prior calendar year’s distributions on your federal income tax return. This information will also be reported to the Internal Revenue Service (“IRS”). Be sure to keep this Form 1099 as a permanent record. A fee may be charged for any duplicate information requested.

Tax Consequences

Except where noted, the discussion below addresses only the U.S. federal income tax consequences of an investment in the Fund and does not address any foreign, state or local tax consequences.


ASG Global Alternatives Fund		19		Prospectus – May 1, 2009

FUND SERVICES

Distributions by the Fund to retirement plans and other investors that qualify for tax-exempt treatment under federal income tax laws generally will not be taxable.

Compensation to Securities Dealers

The Distributor, the Fund’s adviser and their respective affiliates will, out of their own resources, which generally come directly or indirectly from fees paid by the Funds, make payments to certain dealers and other financial intermediaries that satisfy certain criteria established from time to time by the Distributor. Payments may vary based on sales, the amount of assets a dealer’s or intermediary’s clients have invested in the Funds, and other factors. These payments may also take the form of sponsorship of seminars or informational meetings or payments for attendance by persons associated with a dealer or intermediary at informational meetings. The Distributor and its affiliates may also make payments for recordkeeping and other transfer agency-related services to dealers and intermediaries that sell Fund shares.


ASG Global Alternatives Fund		20		Prospectus – May 1, 2009

FUND SERVICES

The payments described in this section, which may be significant to the dealers and the financial intermediaries, may create an incentive for a dealer or financial intermediary or their representatives to recommend or sell shares of a particular fund or share class over other mutual funds or share classes. Additionally, these payments may result in the Funds receiving certain marketing or servicing advantages that are not generally available to mutual funds that do not make such payments, including placement on a sales list, including a preferred or select sales list, or in other sales programs. These payments may create potential conflicts of interest between an investor and a dealer or other financial intermediary who is recommending a particular mutual fund over other mutual funds. Before investing, you should consult with your financial representative and review carefully any disclosure by the dealer or other financial intermediary as to what monies it receives from mutual fund advisers and distributors, as well as how your financial representative is compensated. Please see the SAI for additional information about payments made by the Distributor and its affiliates to dealers and intermediaries. Please also contact your dealer or financial intermediary for details about payments it may receive.
