Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the sameand all dividends and distributions are reinvested. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	Class A4		Class B4				Class  C4
			If shares are redeemed		If shares are not redeemed		If shares are redeemed		If shares are not redeemed
1 year	$	692	$	701	$	201	$	301	$	201
3 years	$	940	$	921	$	621	$	621	$	621
5 years	$	1,207	$	1,268	$	1,068	$	1,068	$	1,068
10 years**	$	1,967	$	2,110	$	2,110	$	2,306	$	2,306

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” in the Statutory Prospectus. A 1.00% contingent deferred sales charge (“CDSC”) applies with respect to certain purchases of Class A shares greater than $1,000,000 redeemed within 1 year after purchase, but not to any other purchases or redemptions of Class A shares.

2 Other expenses have been restated to reflect current expenses.

3 Loomis Sayles has given a binding contractual undertaking to the Fund to limit the amount of the Fund’s total annual fund operating expenses, exclusive of expenses estimated to be indirectly borne by the Fund through investments in certain pooled investment vehicles, brokerage expenses, interest expense, taxes and organizational and extraordinary expenses, such as litigation and indemnification expenses, to 1.25%, 2.00% and 2.00% of the Fund’s average daily net assets for Class A, Class B and Class C shares, respectively. This undertaking is in effect through January 31, 2011 and will be reevaluated on an annual basis. This undertaking may be terminated before then only with the consent of the Fund’s Board of Trustees. Loomis Sayles will be permitted to recover, on a class-by-class basis, expenses it has borne through the undertakings described above to the extent that a Fund’s expenses in later periods fall below the annual rates set forth in the relevant undertaking. A Fund will not be obligated to pay any such deferred fees and expenses more than one year after the end of the fiscal year in which the fee and expense was deferred.

4 The example is based on the Total Annual Fund Operating Expenses for all periods.

* Transaction fees may be charged for expedited payments. See the section “Selling Shares” in the Statutory Prospectus.

** Class B shares automatically convert to Class A shares after 8 years; therefore, in years 9 and 10 Class B amounts are calculated using Class A expenses.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During its most recently ended fiscal year, the Fund’s portfolio turnover rate was 191% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies

Under normal market conditions, the Fund will invest primarily in equity securities, including common stocks, convertible securities and warrants. The Fund focuses on stocks of large capitalization companies, but the Fund may invest in companies of any size.

The Fund normally invests across a wide range of sectors and industries. The Fund’s portfolio manager employs a growth style of equity management that emphasizes companies with sustainable competitive advantages, secular long-term cash flow growth returns on invested capital above their cost of capital and the ability to manage for profitable growth that can create long-term value for shareholders. The Fund’s portfolio manager aims to invest in companies when they trade at a significant discount to the estimate of intrinsic value.

The Fund will consider selling a portfolio investment when the portfolio manager believes the issuer’s investment fundamentals are beginning to deteriorate, when the investment no longer appears consistent with the portfolio manager’s investment methodology, when the Fund must meet redemptions, in order to take advantage of more attractive investment opportunities, or for other investment reasons which a portfolio manager deems appropriate.

The Fund may also invest any portion of its assets in equity securities of Canadian issuers, up to 20% of its assets in other foreign securities, including emerging markets, engage in foreign currency transactions, invest in options for hedging and investment purposes and Rule 144A securities. The Fund may also engage in active and frequent trading of securities.

Principal Risks

The principal risks of investing in the Fund are summarized below. The Fund does not represent a complete investment program. You may lose money by investing in the Fund.

Currency Risk: Fluctuations in the exchange rates between different currencies may negatively affect an investment.

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

Equity Securities Risk: The value of the Fund’s investments in equity securities could be subject to 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. Rule 144A securities may be less liquid than other equity securities. Equity securities may include common stock, preferred stocks, warrants, securities convertible into common and preferred stocks and other equity-like interests in an entity. Growth stocks are generally more

Natixis Equity Funds 2

sensitive to market movements than other types of stocks primarily because their stock prices are based heavily on future expectations. If Loomis Sayles’ assessment of the prospects for a company’s growth is wrong, or if Loomis Sayles’ judgment of how other investors will value the company’s growth is wrong, then the price of the company’s stock may fall or not approach the value that Loomis Sayles has placed on it. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s bonds and preferred stock generally take precedence over the claims of those who own common stock.

Foreign Securities Risk: The Fund’s investments in foreign securities are subject to foreign currency fluctuations. Foreign securities may be subject to higher volatility than U.S. securities, varying degrees of regulation and limited liquidity. Greater political, economic, credit and information risks are also associated with foreign securities.

Management Risk: A strategy used by the Fund’s portfolio managers may fail to produce the intended result.

Market Risk: The market value of a security will 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.

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.

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. Illiquid investments may also be difficult to value.

Risk/Return Bar Chart and Table

The bar chart and table shown below provide some 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 to 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. Updated performance information is available online at www.funds.natixis.com and/or by calling the Fund toll-free at 800-225-5478.

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.

Total Returns for Class A Shares†

The Fund’s Class A shares total return year to date as of March 31, 2010 was 4.91%.

The table below shows how average annual total returns for Class A, Class B and Class C shares of the Fund (before and after taxes for Class A) for the one-year, five-year and ten-year periods compare to those of the Russell 1000 Growth Index, an unmanaged index measuring the performance of those Russell 1000 companies with higher price-to-book ratios and higher forecasted growth values. The Fund’s total returns reflect, on a class-by-class basis, expenses and the maximum sales charge that you may be required to pay when you buy or redeem the Fund’s shares. Class B total returns do not reflect the automatic conversion of Class B shares to Class A shares after eight years.

Average Annual Total Returns† (for the periods ended December 31, 2009)	Past 1 Year		Past 5 Years		Past 10 Years
Loomis Sayles Growth Fund Class A – Return Before Taxes	24.43	%	-4.17	%	-5.00	%
Return After Taxes on Distributions	24.43	%	-4.17	%	-6.36	%
Return After Taxes on Distributions & Sales of Fund Shares	15.88	%	-3.50	%	-4.73	%
Class B – Returns Before Taxes	26.27	%	-4.13	%	-5.16	%
Class C – Returns Before Taxes	30.55	%	-3.70	%	-5.14	%
Russell 1000 Growth Index	37.21	%	1.63	%	-3.99	%

† The returns shown in the bar chart and table for Class A shares for periods prior to September 15, 2003 reflect the results of the Fund’s Retail Class shares, which were converted to Class A shares on September 12, 2003. The prior Retail Class performance has been restated to reflect net expenses and sales loads of Class A shares. For periods prior to the inception of Class B and Class C shares (September 12, 2003), performance shown for Class B and Class C shares has been based on the Fund’s prior Institutional Class performance, restated to reflect the net expenses and sales loads of the Fund’s Class B and Class C shares, respectively.

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.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of the Fund shares and related services.
