AEW Capital Management, L.P. (“AEW” or the “Adviser”) has given a binding contractual undertaking to the Fund to limit the amount of the Fund’s total annual fund operating expenses to 1.15%, 1.90%, 0.85%, 1.15% and 0.90% of the Fund’s average daily net assets for Class A, C, N, T and Y shares, respectively, exclusive of brokerage expenses, interest expense, taxes, acquired fund fees and expenses, organizational and extraordinary expenses, such as litigation and indemnification expenses. This undertaking is in effect through May 31, 2024 and may be terminated before then only with the consent of the Fund’s Board of Trustees. The Adviser will be permitted to recover, on a class by class basis, management fees waived and/or expenses reimbursed to the extent that expenses in later periods fall below both (1) the class’ applicable expense limitation at the time such amounts were waived/reimbursed and (2) the class’ current applicable expense limitation. The Fund will not be obligated to repay any such waived/reimbursed fees and expenses more than one year after the end of the fiscal year in which the fees or expenses were waived/reimbursed.

Natixis Advisors, LLC (“Natixis Advisors”) has given a binding contractual undertaking to the Fund to reimburse any and all transfer agency expenses for Class N shares. This undertaking is in effect through May 31, 2024 and may be terminated before then only with the consent of the Fund’s Board of Trustees.

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 (except where indicated). The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same, except that the example is based on the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement assuming that such waiver and/or reimbursement will only be in place through the date noted above and on the Total Annual Fund Operating Expenses for the remaining periods. The example for Class C shares for the ten-year period reflects the conversion to Class A shares after eight years. The example does not take into account brokerage commissions and other fees to financial intermediaries that you may pay on your purchases and sales of shares of the Fund. Although your actual costs may be higher or lower, based on these assumptions your costs would be:


If shares are redeemed:	1 year		3 years		5 years		10 years
Class A	$	685	$	971	$	1,278	$	2,147
Class C	$	293	$	651	$	1,136	$	2,282
Class N	$	87	$	323	$	578	$	1,307
Class T	$	364	$	660	$	978	$	1,877
Class Y	$	92	$	343	$	613	$	1,386


If shares are not redeemed:	1 year		3 years		5 years		10 years
Class C	$	193	$	651	$	1,136	$	2,282

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 90% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies

Under normal circumstances, the Fund will invest at least 80% of its net assets (plus any borrowings made for investment purposes) in securities, including common stocks and preferred stocks, of real estate investment trusts (“REITs”) and/or real estate-related companies (e.g., real estate operating companies). 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. To qualify as a REIT, a company must distribute a significant percentage of its taxable income to shareholders in the form of dividends (at least 90% in the U.S.); this dividend payout ratio is higher than that of non-REIT companies. 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. The Fund intends to meet its investment goal by investing primarily in a portfolio of securities of REITs and real estate companies, including those that are primarily focused on income-producing commercial property and real estate development. Companies in the real estate industry, including REITs and real estate operating companies in which the Fund may invest may have relatively small market capitalizations. The Fund invests in securities of issuers located in no fewer than three regions, North America, Europe and Asia Pacific. Under normal circumstances, the Fund’s regional weightings will be +/- 10% of the regional weightings of the Fund’s benchmark, the FTSE EPRA Nareit Developed Index (Net). Although the Fund does not seek to track any particular index, the Fund will be diversified in terms of geographic and property type exposures, and the FTSE EPRA Nareit Developed Index (Net) may be used as a benchmark for the regional weighting of the Fund’s portfolio. The Fund may invest up to 10% of its assets in securities of companies located in emerging markets. For the purposes of determining whether a particular country is considered an emerging market, the Fund uses the designation set forth by the FTSE EPRA Nareit Emerging Index. The Fund follows a focused investment approach and typically holds 50 to 60 securities.

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 underlying real estate assets and company management, as well as the overall influence of capital markets.

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. These estimates are formulated by the investment teams in each region based on a detailed analysis of historical trends and expectations for the future for each company’s financial statements. As a first step in its modeling process, AEW inputs projected financial information for each company. After completion of preliminary pro forma statements, the assumptions utilized to create the pro forma statements are generally discussed with representatives from each company. 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 capital markets value and real estate value incorporate factors that AEW believes influence the valuation of the cash flows by these different types of investors. These factors are the quantification of a broad array of subjective characteristics that AEW believes are important in the relative valuation process for both sectors and individual stocks. 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.

Catalysts: When evaluating a security, AEW also seeks to identify potential catalysts, such as changes in interest rates, regional and local economic conditions and other factors, that in its opinion, could cause the marketplace to re-value the security upwards in the near term. These catalysts can be macro-economic (e.g. interest rate expectations), market-driven or company-specific (e.g. a company’s development pipeline) in nature.

ESG: AEW seeks to identify environmental, social, and governance (“ESG”) factors that it believes are most relevant to real estate investments in the Fund’s investable universe. ESG factors may include, among other things, the environmental performance of buildings, diversity, equity and inclusion policies, corporate giving, and Board diversity. AEW incorporates insights from fundamental research and company meetings alongside third party data and ESG data sourced directly from the issuer into a proprietary ESG risk score, which is an input into AEW’s securities valuation analysis. While AEW considers ESG factors in all buy and sell decisions for the Fund, the ESG profile of an investment will not be prioritized over other considerations in AEW’s investment selection process. The Fund may continue to invest in an issuer with a lower ESG score if AEW believes the investment’s valuation remains attractive as measured by other factors.

Principal Investment 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.

Fund shares are not bank deposits and are not guaranteed, endorsed or insured by the Federal Deposit Insurance Corporation or any other government agency, and are subject to investment risks, including possible loss of the principal invested.

The significance of any specific risk to an investment in the Fund will vary over time, depending on the composition of the Fund’s portfolio, market conditions, and other factors. You should read all of the risk information presented below carefully, because any one or more of these risks may result in losses to the Fund.

Real Estate Risk: Because the Fund concentrates its investments in REITs and 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. Investments in the real estate industry, including REITs, are particularly sensitive to economic downturns and are sensitive to factors such as changes in real estate values, property taxes and tax laws, 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 also may 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 mortgage loans held by the REIT. REITs are also subject to default and prepayment risk. Many REITs are highly leveraged, increasing their risk. 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- and Mid-Capitalization Companies Risk: Compared to large-capitalization companies, small- and mid-capitalization companies are more likely to have limited product lines, markets or financial resources. Stocks of these companies often trade less frequently and in limited volume and their prices may fluctuate more than stocks of large-capitalization companies. As a result, it may be relatively more difficult for the Fund to buy and sell securities of small- and mid-capitalization companies.

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. Value stocks can perform differently from the market as a whole and from other types of stocks. Value stocks also present the risk that their lower valuations fairly reflect their business prospects and that 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. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s bonds generally take precedence over the claims of those who own preferred stock or common stock.

Currency Risk: Fluctuations in the exchange rates between different currencies may negatively affect an investment. The Fund may be subject to currency risk because it may invest in securities or other instruments denominated in, or that generate income denominated in, foreign currencies. The Fund may elect not to hedge currency risk, or may hedge such risk imperfectly, which may cause the Fund to incur losses that would not have been incurred had the risk been hedged.

Foreign Securities Risk: Investments in foreign securities may be subject to greater political, economic, environmental, credit/counterparty and information risks. The Fund’s investments in foreign securities also are subject to foreign currency fluctuations and other foreign currency-related risks. Foreign securities may be subject to higher volatility than U.S. securities, varying degrees of regulation and limited liquidity.

Emerging Markets Risk: In addition to the risks of investing in foreign investments generally, emerging markets investments are subject to greater risks arising from political or economic instability, war, nationalization or confiscatory taxation, currency exchange or repatriation restrictions, sanctions by other countries (such as the United States or the European Union), new or inconsistent government treatment of or restrictions on issuers and instruments, and an issuer’s unwillingness or inability to make dividend, principal or interest payments on its securities. Emerging markets companies may be smaller and have shorter operating histories than companies in developed markets.

Cybersecurity and Technology Risk: The Fund, its service providers, and other market participants increasingly depend on complex information technology and communications systems, which are subject to a number of different threats and risks that could adversely affect the Fund and its shareholders. Cybersecurity and other operational and technology issues may result in financial losses to the Fund and its shareholders.

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.

Large Investor Risk: Ownership of shares of the Fund may be concentrated in one or a few large investors. Such investors may redeem shares in large quantities or on a frequent basis. Redemptions by a large investor can affect the performance of the Fund, may increase realized capital gains, including short-term capital gains taxable as ordinary income, may accelerate the realization of taxable income to shareholders and may increase transaction costs. These transactions potentially limit the use of any capital loss carryforwards and certain other losses to offset future realized capital gains (if any). Such transactions may also increase the Fund’s expenses.

Liquidity Risk: Liquidity risk is the risk that the Fund may be unable to find a buyer for its investments when it seeks to sell them or to receive the price it expects. Decreases in the number of financial institutions willing to make markets in the Fund’s investments or in their capacity or willingness to transact may increase the Fund’s exposure to this risk. Events that may lead to increased redemptions, such as market disruptions or increases in interest rates, may also negatively impact the liquidity of the Fund’s investments when it needs to dispose of them. If the Fund is forced to sell its investments at an unfavorable time and/or under adverse conditions in order to meet redemption requests, such sales could negatively affect the Fund. During times of market turmoil, there may be no buyers or sellers for securities in certain asset classes. In other circumstances, liquid investments may become illiquid. Liquidity issues may also make it difficult to value the Fund’s investments. The Fund may invest in liquid investments that become illiquid due to financial distress, or geopolitical events such as sanctions, trading halts or wars.

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

Market/Issuer Risk: The market value of the Fund’s investments will move up and down, sometimes rapidly and unpredictably, based upon overall market and economic conditions, as well as a number of reasons that directly relate to the issuers of the Fund’s investments, such as management performance, financial condition and demand for the issuers’ goods and services.

Models and Data Risk: The Adviser utilizes various proprietary quantitative models to identify investment opportunities. There is a possibility that one or all of the quantitative models may fail to identify profitable opportunities at any time. Furthermore, the models may incorrectly identify opportunities and these misidentified opportunities may lead to substantial losses for the Fund. Models may be predictive in nature and such models may result in an incorrect assessment of future events. Data used in the construction of models may prove to be inaccurate or stale, which may result in losses for the Fund.

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, ten-year, and life-of-class periods (as applicable) compare to those of a broad measure of market performance. Performance for Class C shares includes the automatic conversion to Class A shares after eight years. 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 im.natixis.com and/or by calling the Fund toll-free at 800-225-5478.

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 Y Shares


	Highest Quarterly Return: First Quarter 2019, 15.22% Lowest Quarterly Return: First Quarter 2020, -24.31%

The Fund’s Class Y shares total return year to date as of March 31, 2023 was 1.89%.


Average Annual Total Returns
(for the periods ended December 31, 2022)	Past 1 Year	Past 5 Years	Past 10 Years	Life of Class (5/1/13)
Class Y - Return Before Taxes	-25.76%	1.31%	4.96%	--
Return After Taxes on Distributions	-26.28%	-0.85%	2.10%	--


Average Annual Total Returns
(for the periods ended December 31, 2022)	Past 1 Year	Past 5 Years	Past 10 Years	Life of Class (5/1/13)
Return After Taxes on Distributions and Sale of Fund Shares	-14.88%	0.76%	3.37%	--
Class A - Return Before Taxes	-30.14%	-0.12%	4.08%	--
Class C - Return Before Taxes	-27.20%	0.30%	4.06%	--
Class N - Return Before Taxes	-25.72%	1.36%	--	3.89%
Class T - Return Before Taxes	-27.76%	0.55%	4.43%	--
FTSE EPRA Nareit Developed Index (Net)	-25.09%	-0.23%	2.99%	1.76%

The Fund did not have Class T shares outstanding during the periods shown above. The returns of Class T shares would have been substantially similar to the returns of the Fund’s other share classes because they would have been invested in the same portfolio of securities and would only differ to the extent the other share classes did not have the same expenses. Performance of Class T shares shown above is that of Class A shares, which have the same expenses as Class T shares, restated to reflect the different sales load applicable to Class T shares.

The Fund revised its investment strategies at the close of business on May 31, 2019, and performance may have been different had the current investment strategies been in place for all periods shown.

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 shares through tax-advantaged 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. Index performance reflects no deduction for fees, expenses or taxes. The Return After Taxes on Distributions and Sale of Fund Shares for the 1-year period exceeds the Return Before Taxes due to an assumed tax benefit from losses on a sale of Fund shares at the end of the measurement period.

More About Goals and Strategies

AEW Global Focused Real Estate Fund

Investment Goal

The Fund seeks to provide investors with above-average income and long-term growth of capital. The Fund’s investment goal 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

Temporary Defensive Measures

Temporary defensive measures may be used by the Fund during adverse economic, market, political or other conditions. In this event, the Fund may hold any portion of its assets in cash (U.S. dollars, foreign currencies or multinational currency units) and/or invest in cash equivalents such as money market instruments or high-quality debt securities as it deems appropriate. The Fund may miss certain investment opportunities if it uses defensive strategies and thus may not achieve its investment goal.

Percentage Investment Limitations

Except as set forth in the 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.

Portfolio Holdings

A description of the Fund’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the section “Portfolio Holdings Information” in the SAI.

A “snapshot” of the Fund’s investments will 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 30 days, is available on the Fund’s website at im.natixis.com/us/fund-documents (in the “Daily/Monthly/Quarterly” column under the “Holdings” section, click the download button for the Fund). These holdings will remain accessible on the website until the Fund files its Form N-CSR or Form N-PORT with the SEC for the period that includes the date of the information.

More About Risks

This section provides more information on principal risks that may affect the Fund’s portfolio, as well as information on additional risks the Fund may be subject to because of its investments or practices. In seeking to achieve its investment goals, the Fund may also invest in various types of securities and engage in various investment practices which are not a principal focus of the Fund and therefore are not described in this Prospectus. These securities and investment practices and their associated risks are discussed in the Fund’s SAI, which is available without charge upon request (see back cover). The significance of any specific risk to an investment in the Fund will vary over time, depending on the composition of the Fund’s portfolio, market conditions, and other factors. You should read all of the risk information presented below carefully, because any one or more of these risks may result in losses to the Fund.

Recent Market Events Risk

The COVID-19 pandemic resulted in, among other things, significant market volatility, exchange trading suspensions and closures, declines in global financial markets, higher default rates, and economic downturns and recessions, and may continue to have similar effects in the future. There remains significant uncertainty surrounding the magnitude, duration, reach, costs, and effects of the COVID-19 pandemic, as well as actions that have been or could be taken by governmental authorities or other third-parties in the future, and it is difficult to predict its potential impacts on a Fund’s investments. The COVID-19 pandemic and efforts to contain its spread may also exacerbate other risks that apply to the Fund and may exacerbate existing economic, political, or social tensions.

In addition, Russia’s military invasion of Ukraine in February 2022, the resulting responses by the United States and other countries, and the potential for wider conflict could increase volatility and uncertainty in the financial markets and adversely affect regional and global economies. These and any related events could significantly impact a Fund’s performance and the value of an investment in the Fund, even if the Fund does not have direct exposure to Russian issuers or issuers in other countries affected by the invasion.

Currency Risk

Fluctuations in the exchange rates between different currencies may negatively affect an investment. The Fund may be subject to currency risk because it may invest in currency-related instruments and/or securities or other instruments denominated in, or that generate income denominated in, foreign currencies. The market for some or all currencies may from time to time have low trading volume and become illiquid, which may prevent the Fund from effecting a position or from promptly liquidating unfavorable positions in such markets, thus subjecting the Fund to substantial losses. The Fund may elect not to hedge currency risk, or may hedge such risk imperfectly, which may cause the Fund to incur losses that would not have been incurred had the risk been hedged.

Cybersecurity and Technology Risk

The Fund, its service providers, and other market participants increasingly depend on complex information technology and communications systems, which are subject to a number of different threats and risks that could adversely affect the Fund and its shareholders. These risks include, among others, theft, misuse, and improper release of confidential or highly sensitive information relating to the Fund and its shareholders, as well as compromises or failures to systems, networks, devices and applications relating to the operations of the Fund and its service providers. Power outages, natural disasters, equipment malfunctions and processing errors that threaten these systems, as well as market events that occur at a pace that overloads these systems, may also disrupt

business operations or impact critical data. Any problems relating to the performance and effectiveness of security procedures used by the Fund or its service providers to protect the Fund’s assets, such as algorithms, codes, passwords, multiple signature systems, encryption and telephone call-backs, may have an adverse impact on an investment in the Fund. Cybersecurity and other operational and technology issues may result in financial losses to the Fund and its shareholders, impede business transactions, violate privacy and other laws, subject the Fund to certain regulatory penalties and reputational damage, and increase compliance costs and expenses. Furthermore, as the Fund’s assets grow, it may become a more appealing target for cybersecurity threats such as hackers and malware. Although the Fund has developed processes, risk management systems, and business continuity plans designed to reduce these risks, the Fund does not directly control the cybersecurity defenses, operational and technology plans and systems of its service providers, financial intermediaries and companies in which it invests or with which it does business. The Fund and its shareholders could be negatively impacted as a result. Similar types of cybersecurity risks also are present for issuers of securities in which the Fund invests, which could result in material adverse consequences for such issuers, and may cause the Fund’s investment in such securities to lose value.

Emerging Markets Risk

In addition to the risks of investing in foreign investments generally, emerging markets investments are subject to greater risks arising from political or economic instability, war, nationalization or confiscatory taxation, currency exchange or repatriation restrictions, sanctions by other countries (such as the United States or the European Union), new or inconsistent government treatment of or restrictions on new issuers and instruments, and an issuer’s unwillingness or inability to make dividend, principal or interest payments on its securities. Emerging markets companies may be smaller and have shorter operating histories than companies in developed markets. In addition, pandemics and outbreaks of contagious diseases may exacerbate pre-existing problems in emerging market countries with less established health care systems.

Economic and Political Risks. Emerging market countries often experience instability in their political and economic structures and have less market depth, infrastructure, capitalization and regulatory oversight than more developed markets. Government actions could have a significant impact on the economic conditions in such countries, which in turn would affect the value and liquidity of the assets of the Fund invested in emerging market securities. Specific risks that could decrease the Fund’s return include seizure of a company’s assets, restrictions imposed on payments as a result of blockages on foreign currency exchanges or sanctions and unanticipated social or political occurrences.

The ability of the government of an emerging market country to make timely payments on its debt obligations will depend on many factors, including the extent of its reserves, fluctuations in interest rates and access to international credit and investments. A country that has non-diversified exports or relies on certain key imports will be subject to greater fluctuations in the pricing of those commodities. Failure to generate sufficient earnings from foreign trade will make it difficult for an emerging market country to service its foreign debt.

Companies trading in developing securities markets are generally smaller and have shorter operating histories than companies trading in developed markets. Foreign investors may be required to register the proceeds of sales. Settlement of securities transactions in emerging markets may be subject to risk of loss and may be delayed more often than transactions settled in the United States. Disruptions resulting from social and political factors may cause the securities markets to close. If extended closings were to occur, the liquidity and value of the Fund’s assets invested in corporate debt obligations of emerging market companies would decline.

Investment Controls; Repatriation. Foreign investment in emerging market country debt securities is restricted or controlled to varying degrees. These restrictions may at times limit or preclude foreign investment in certain emerging market country debt securities. Certain emerging market countries require government approval of investments by foreign persons, limit the amount of investments by foreign persons in a particular issuer, limit investments by foreign persons only to a specific class of securities of an issuer that may have less advantageous rights than the classes available for purchase by domiciliaries of the countries and/or impose additional taxes or controls on foreign investors or currency transactions. Certain emerging market countries may also restrict investment opportunities in issuers in industries deemed important to national interests.

Emerging market countries may require governmental approval for the repatriation of investment income, capital or proceeds of sale of securities by foreign investors. In addition, if a deterioration occurs in an emerging market country’s balance of payments, the country could impose temporary restrictions on foreign capital remittances. The Fund could be adversely affected by delays in, or a refusal to grant, any required governmental approval for repatriation of capital, as well as by the application to the Fund of any restrictions on investments. Investing in local markets in emerging market countries may require the Fund to adopt special procedures, seek local governmental approvals or take other actions, each of which may involve additional costs to the Fund.

Equity Securities Risk

The value of your investment in the Fund is based on the market value (or price) of the securities the Fund holds. You may lose money on your investment due to unpredictable declines in the value of individual securities and/or periods of below-average performance in individual securities, industries or in the equity market as a whole. This may impact the Fund’s performance and may result in higher portfolio turnover, which may increase the tax liability to taxable shareholders and the expenses incurred by the Fund. The market value of a security can change daily due to political, economic and other events that affect the securities markets generally, as well as those that affect particular companies or governments. These price movements, sometimes called volatility, will vary depending on the types of securities the Fund owns and the markets in which they trade. Historically, the equity markets have moved in cycles, and the value of the Fund’s equity securities may fluctuate drastically from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response to such trends and developments. Securities issued in initial public offerings 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 under the Securities Act of 1933 (“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. If the Adviser’s assessment of the prospects for a company’s growth is wrong, or if the Adviser’s 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 the Adviser has placed on it. Value stocks can perform differently from the market as a whole and from other types of stocks. Value stocks also present the risk that their lower valuations fairly reflect their business prospects and that 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. 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 generally take precedence over the claims of those who own preferred stock or common stock.

Focused Investment Risk

Because the Fund may invest in a particular industry, such as the real estate industry, or 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 (“NAV”). Investments in the real estate industry are particularly sensitive to economic downturns. See the section “Real Estate Risk” below.

Foreign Securities Risk

Foreign securities risk 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, disclosure, custody and auditing standards and practices of foreign countries differ, in some cases significantly, from U.S. standards and practices, and are often not as rigorous. The Public Company Accounting Oversight Board, which regulates auditors of U.S. public companies, is unable to inspect audit work papers in certain foreign countries. Many countries, including developed nations and emerging markets, are faced with concerns about high government debt levels, credit rating downgrades, the future of the euro as a common currency, possible government debt restructuring and related issues, all of which may cause the value of the Fund’s non-U.S. investments to decline. Nationalization, expropriation or confiscatory taxation, currency blockage, the imposition of sanctions or threat thereof by other countries (such as the United States), political changes or diplomatic developments may impair the Fund’s ability to buy, sell, hold, receive, deliver or otherwise transact in certain securities and may also cause the value of the Fund’s non-U.S. investments to decline. When imposed, foreign withholding or other taxes reduce the Fund’s return on foreign securities. In the event of nationalization, expropriation, confiscation, or other government action, intervention, or restriction, the Fund could lose its entire investment in a particular foreign issuer or country. Investments in emerging markets may be subject to these risks to a greater extent than those in more developed markets and securities of developed market companies that conduct substantial business in emerging markets may also be subject to greater risk. These risks also apply to securities of foreign issuers traded in the United States or through depositary receipt programs such as American Depositary Receipts. To the extent the Fund invests a significant portion of its assets in a specific geographic region, the Fund may have more exposure to regional political, economic, environmental, credit/counterparty and information risks. In addition, foreign securities may be subject to increased credit/counterparty risk because of the potential difficulties of requiring foreign entities to honor their contractual commitments.

Large Investor Risk

Ownership of shares of the Fund may be concentrated in one or a few large investors. Such investors may redeem shares in large quantities or on a frequent basis. If a large investor redeems a portion or all of its investment in the Fund or redeems frequently, the Fund may be forced to sell investments at unfavorable times or prices, which can affect the performance of the Fund and may increase realized capital gains, including short-term capital gains taxable as ordinary income. In addition, such transactions may accelerate the realization of taxable income to shareholders if the Fund’s sales of investments result in gains, and also may increase transaction costs. These transactions potentially limit the use of any capital loss carryforwards and certain other losses to offset future realized capital gains (if any). Such transactions may also increase the Fund’s expenses or could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratios.

Liquidity Risk

Liquidity risk is the risk that the Fund may be unable to find a buyer for its investments when it seeks to sell them or to receive the price it expects. Decreases in the number of financial institutions willing to make markets in the Fund’s investments or in their capacity or willingness to transact may increase the Fund’s exposure to this risk. Events that may lead to increased redemptions, such as market disruptions or increases in interest rates, may also negatively impact the liquidity of the Fund’s investments when it needs to dispose of them. If the Fund is forced to sell its investments at an unfavorable time and/or under adverse conditions in order to meet redemption requests, such sales could negatively affect the Fund. Securities acquired in a private placement, such as Rule 144A securities, are generally subject to significant liquidity risk because they are subject to strict restrictions on resale and there may be no liquid secondary market or ready purchaser for such securities. In other circumstances, liquid investments may become illiquid. Liquidity issues may also make it difficult to value the Fund’s investments. The Fund may invest in liquid investments that become illiquid due to financial distress, or geopolitical events such as sanctions, trading halts or wars. In some cases, especially during periods of market turmoil, there may be no buyers or sellers for securities in certain asset classes and a redemption may dilute the interest of the remaining shareholders.

Management Risk

Management risk is the risk that the portfolio managers’ 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 portfolio managers 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 portfolio managers expect to appreciate in value may, in fact, decline. Similarly, in some cases, derivative and other investment techniques may be unavailable or the portfolio managers may determine not to use them, even under market conditions where their use could have benefited the Fund.

Market/Issuer Risk

The market value of the Fund’s investments will move up and down, sometimes rapidly and unpredictably, based upon political, regulatory, market, economic, and social conditions, as well as developments that impact specific economic sectors, industries, or segments of the market, including conditions that directly relate to the issuers of the Fund’s investments, such as management performance, financial condition and demand for the issuers’ goods and services. The Fund is subject to the risk that geopolitical events will adversely affect global economies and markets. War, terrorism, and related geopolitical events have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on global economies and markets. Likewise, natural and environmental disasters and epidemics or pandemics may be highly disruptive to economies and markets. Risks relating to ESG factors may impact the performance of securities in which the Fund invests.

Models and Data Risk

The Adviser utilizes various proprietary quantitative models to identify investment opportunities. There is a possibility that one or all of the quantitative models may fail to identify profitable opportunities at any time. Furthermore, the models may incorrectly identify opportunities and these misidentified opportunities may lead to substantial loss. Models may be predictive in nature and such models may result in an incorrect assessment of future events. Data used in the construction of models may prove to be inaccurate or stale, which may result in losses for a Fund. Investments selected using the models may perform differently than expected as a result of the market factors used in creating models, the weight given to each such market factor, changes from the market factors’ historical trends and technical issues in the construction and implementation of the models (e.g., data problems, and/or software issues). The Adviser’s judgments about the weightings among various models and strategies may be incorrect, adversely affecting performance.

Real Estate Risk

Because the Fund concentrates its investments in REITs and 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. Investments in the real estate industry including REITs are particularly sensitive to economic downturns and are also 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. Many REITs are highly leveraged, increasing their risk. While certain of these risk factors may affect only one or a few real estate sectors at a time, others may affect the real estate industry broadly. For example, the value of REIT common shares may decline when interest rates rise. During periods of high interest rates, REITs and other real estate companies may lose appeal for investors who may be able to obtain higher yields from other income-producing investments. High interest rates may also mean that financing for property purchases and improvements is more costly and difficult to obtain. 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- and Mid-Capitalization Companies Risk

Compared to companies with large market capitalization, small- and mid-capitalization companies are more likely to have limited product lines, markets or financial resources, or to depend on a small, inexperienced management group. Securities of these companies often trade less frequently and in limited volume and their prices may fluctuate more than stocks of large-capitalization companies. Securities of small- and mid-capitalization companies may therefore be more vulnerable to adverse developments than those of large-capitalization companies. As a result, it may be relatively more difficult for the Fund to buy and sell securities of small- and mid-capitalization companies.

Fund Services

Investing in the Fund

Choosing a Share Class

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 a number of factors, including the size of your investment and how long you intend to hold your shares. Certain share classes and certain shareholder features may not be available to you if you hold your shares through a financial intermediary. Your financial representative can help you decide which class of shares is most appropriate for you. The Fund may engage financial intermediaries to receive purchase, exchange and sell orders on its behalf. Accounts established directly with the Fund will be serviced by the Fund’s transfer agent. The Fund, the Fund’s transfer agent and the Distributor do not provide investment advice.

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 pay higher expenses than Class N and Class Y shares.

•	You do not pay a sales charge if your total investment reaches $1 million or more, but you may pay a charge on redemptions if you redeem these shares within 18 months 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, Class N, Class T and Class Y shares.

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

•

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 18 months of purchase.

•

Except as noted below, Class C shares will automatically convert to Class A shares after eight years. Please see the section “Exchanging or Converting Shares” for details regarding a conversion of shares. Generally, to be eligible to have your Class C shares automatically converted to Class A shares, the Fund or the financial intermediary through which you purchased your shares will need to have records verifying that your Class C shares have been held for eight years. Due to operational limitations at your financial intermediary, your ability to have your Class C shares automatically converted to Class A shares may be limited. Group retirement plans of certain financial intermediaries who hold Class C shares with the Fund in an omnibus account do not track participant level aging of shares and therefore these shares will not be eligible for an automatic conversion. Certain intermediaries may convert your Class C shares to Class A shares in accordance with a conversion schedule that may differ from the one described above. Please consult your financial representative for more information.

Class N Shares

•	You have a minimum initial investment of $1,000,000. There are several ways to waive this minimum. See the section “Purchase and Sale of Fund Shares.”

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

•	You do not pay a sales charge on redemptions.

•	You pay lower annual expenses than Class A, Class C, and Class T shares, giving you the potential for higher returns per share.

•	You may pay lower annual expenses than Class Y shares.

Class T Shares

•	Class T shares of the Fund are not currently available for purchase.

•	The shares are available to a limited type of investor. See the section “Purchase and Sale of Fund Shares.”

•	You pay a sales charge when you buy Class T shares. This charge is reduced for purchases of $250,000 or more. 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 pay higher expenses than Class N and Class Y shares.

Class Y Shares

•	You have a minimum initial investment of $100,000. There are several ways to waive this minimum. See the section “Purchase and Sale of Fund Shares.”

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

•	You do not pay a sales charge on redemptions.

•	You pay lower annual expenses than Class A, Class C, and Class T shares, giving you the potential for higher returns per share.

•	You may pay higher annual expenses than Class N shares.

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

How Sales Charges Are Calculated

Class A Shares

The price that you pay when you buy Class A shares (the “offering price”) is their NAV 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.

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

**	For purchases of Class A shares of the Fund of $1 million or more, there is no front-end sales charge, but a contingent deferred sales charge (“CDSC”) of 1.00% may apply to redemptions of your shares within 18 months of the date of purchase. See the section “How the CDSC is Applied to Your Shares.”

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. At the time of purchase you must 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 that 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 im.natixis.com (click on “Sales Charges” at the bottom of the home page) or in the 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 $50,000 or more within 13 months.

•

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 (excluding Class T 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.

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 retirement accounts, sole proprietorships, single trust estates and any other individuals acceptable to the Distributor.

Certain Retirement Plan Accounts: The Distributor may, at 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) using the Natixis prototype document. 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.

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:

•	Clients of a financial intermediary that has entered into an agreement with the Distributor and has been approved by the Distributor to offer Fund shares to self-directed investment brokerage accounts that may or may not charge a transaction fee;

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

•	All employees of financial intermediaries under arrangements with the Distributor (this also applies to spouses and children under the age of 21 of those mentioned);

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

•	Certain Retirement Plans. The availability of this pricing may depend upon the policies and procedures of your specific financial intermediary; consult your financial adviser;

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

•	Fee Based Programs of certain broker-dealers, the Adviser or the Distributor. Please consult your financial representative to determine if your fee based program is subject to additional or different conditions or fees; and

•	Registered Investment Advisers investing on behalf of clients in exchange for an advisory, management or consulting fee.

In order to receive Class A shares without a front-end sales charge or a CDSC, you must notify the appropriate Fund of your eligibility at the time of purchase. Due to operational limitations at your financial intermediary, a sales charge or a CDSC may be assessed; please consult your financial representative.

The availability of certain sales charge waivers and discounts will depend on whether you purchase your shares directly from the Fund or through a financial intermediary. Intermediaries may have different policies and procedures regarding the availability of front-end sales load waivers or CDSC waivers, which are discussed below. In all instances, it is the purchaser’s responsibility to notify the Fund or the purchaser’s financial intermediary at the time of purchase of any relationship or other facts qualifying the purchaser for sales charge waivers or discounts. For waivers and discounts not available through a particular intermediary, shareholders will have to purchase Fund shares directly from the Fund or through another intermediary to receive these waivers or discounts. Please see Appendix A to this Prospectus for information regarding eligibility for load waivers and discounts available through specific financial intermediaries, which may differ from those disclosed elsewhere in this Prospectus or in the SAI.

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 returning your original redemption check or sending a new check for some or all of the redemption amount. Please note: for U.S. federal income tax purposes, a redemption generally is treated as 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

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 Certain Retirement Plans to pay plan participants or beneficiaries due to death, disability, separation from service, normal or early retirement, loans from the plan, hardship withdrawals, return of excess contributions, or required minimum distributions (an individual participant’s voluntary distribution or a total plan termination or total plan redemption may incur a CDSC); (2) to make payments through a systematic withdrawal plan; (3) due to shareholder death or disability; (4) to return excess IRA contributions; or (5) to make required minimum distributions (applies only to the amount necessary to meet the required minimum distributions).

Due to operational limitations at your financial intermediary, a CDSC may be assessed, notwithstanding the exemptions above; please consult your financial representative. Please see the SAI for more information on eliminating or reducing front-end sales charges and the CDSC.

Class C Shares

The offering price of Class C shares is their NAV 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.

Class C Contingent Deferred Sales Charges


Year Since Purchase	CDSC on Shares Being Sold
1st	1.00%
Thereafter	0.00%

Eliminating the CDSC

The availability of certain CDSC waivers will depend on whether you purchase your shares directly from the Fund or through a financial intermediary. Intermediaries may have different policies and procedures regarding the availability of CDSC waivers, which are discussed below. In all instances, it is the purchaser’s responsibility to notify the Fund or the purchaser’s financial intermediary at the time of purchase of any relationship or other facts qualifying the purchaser for sales charge waivers or discounts. For waivers not available through a particular intermediary, shareholders will have to purchase Fund shares directly from the Fund or through another intermediary to receive these waivers or discounts. Please see Appendix A to this Prospectus for information regarding eligibility for CDSC discounts available through specific financial intermediaries, which may differ from those disclosed elsewhere in this Prospectus or in the SAI.

As long as the Distributor is notified at the time you sell, the CDSC for Class C shares will generally be eliminated in the following cases: (1) to make distributions from Certain Retirement Plans to pay plan participants or beneficiaries due to death, disability, separation from service, normal or early retirement, loans from the plan, hardship withdrawals, return of excess contributions, or required minimum distributions (an individual participant’s voluntary distribution or a total plan termination or total plan redemption may incur a CDSC); (2) to make payments through a systematic withdrawal plan; (3) due to

shareholder death or disability; (4) to return excess IRA contributions; or (5) to make required minimum distributions (applies only to the amount necessary to meet the required minimum distributions).

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;

•	Calculation is based on either your original purchase price or the current NAV of the shares being sold, whichever is lower in order to minimize your CDSC;

•	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 within the time frame shown above for each class.

A CDSC will not be charged on:

•	Increases in NAV above the purchase price;

•	Shares you acquired by reinvesting your dividends or capital gains distributions; or

•	Exchanges. However, the original purchase date of the shares from which the exchange is made determines if the newly acquired shares are subject to the CDSC when they are sold.

To minimize the amount of the CDSC you may pay when you redeem shares, the relevant Fund will first redeem shares acquired through reinvested dividends and capital gain distributions. Shares will be sold in the order in which they were purchased (earliest to latest).

Class N and Class Y Shares

The offering price of Class N and Class Y shares is their NAV without a front-end load sales charge. No CDSC applies when you redeem your shares. You must meet eligibility criteria in order to invest in Class N or Class Y shares.

Class T Shares

The offering price of Class T shares is their NAV plus a front-end sales charge, which varies depending upon the size of your purchase.


Class T Sales Charges^,*

Your Investment	As a % of offering price	As a % of your investment
Less than $250,000	2.50%	2.56%
$250,000 – $499,999	2.00%	2.04%
$500,000 – $999,999	1.50%	1.52%
$1,000,000 or more	1.00%	1.01%

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

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

Information about purchasing shares of the Fund and sales loads is available on the Fund’s website at im.natixis.com.

Compensation to Securities Dealers
As part of its business strategy, 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 are disclosed in the SAI. Class A, Class C and Class T shares pay an annual service fee each of 0.25% of their respective 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 SAI includes additional information about the payment of some or all of such fees to dealers. Because these distribution fees and service (12b-1) 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 or Class T shares. Similarly, over time the fees for Class A, Class C and Class T shares will increase the cost of your investment and will cost you more than an investment in Class N or Class Y shares.

In addition, the Fund may make payments to financial intermediaries that provide shareholder services to shareholders whose shares are held of record in omnibus, other group accounts (for example, 401(k) plans) or accounts traded through registered securities clearing agents to compensate those intermediaries for services they provide to such shareholders, including, but not limited to, sub-accounting, sub-transfer agency, similar shareholder or participant recordkeeping, shareholder or participant reporting, or shareholder or participant transaction processing (“recordkeeping and processing-related services”). The actual payments, and the services provided, vary from firm to firm. These fees are paid by the Fund (with the exception of Class N shares, which do not bear such expenses) in light of the fact that other costs may be avoided by the Fund where the intermediary, not the Fund’s service provider, provides services to Fund shareholders.

The Distributor, the Fund’s Adviser and each of their respective 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 processing-related services to financial intermediaries that sell Fund shares; such payments will not be made with respect to Class N shares. These payments may be in addition to payments made by the Fund for similar 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 the Fund or a particular share class over other mutual funds or share classes. Additionally, these payments may result in the Fund 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, which are in addition to any amounts you may pay your dealer or other financial intermediary, 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 the services it provides, what monies it receives from mutual funds and their 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.

How to Purchase Shares

The Fund is generally available for purchase in the United States, Puerto Rico, Guam and the U.S. Virgin Islands. The Fund will only accept investments from U.S. citizens with a U.S. address (including an APO or FPO address) or resident aliens with a U.S. address (including an APO or FPO address) and a U.S. taxpayer identification number. U.S. citizens living abroad are not allowed to purchase shares in the Fund. Class N and Class T shares are not eligible to be exchanged or purchased through the website or through the Natixis Funds Automated Voice Response System.

The Fund sells its shares at the NAV next calculated after the Fund receives a properly completed investment order. The Fund generally must receive your properly completed order before the close of regular trading on the New York Stock Exchange (“NYSE”) for your shares to be bought or sold at the Fund’s NAV on that day.

All purchases made by check should be in U.S. dollars and made payable to Natixis Funds. Third party checks, travelers checks, starter checks and credit card convenience checks will not be accepted, except that third party checks under $10,000 may be accepted. You may return an uncashed redemption check from your account to be repurchased back into your account. Upon redemption of an investment by check or by periodic account investment, redemption proceeds may be withheld until the check has cleared or the shares have been in your account for 10 days.

The Fund may periodically close to new purchases of shares or refuse any order to buy shares if the Fund determines that doing so would be in the best interests of the Fund and its shareholders. See the section “Restrictions on Buying, Selling and Exchanging Shares.”

The Fund is not available to new SIMPLE IRA plans using the Natixis Funds’ Prototype document.

You can buy shares of the Fund in several ways:

The Fund may engage financial intermediaries to receive purchase, exchange and sell orders on its behalf. Accounts established directly with the Fund will be serviced by the Fund’s transfer agent. The Fund, the Fund’s transfer agent and the Distributor do not provide investment advice.

Through a financial adviser (certain restrictions may apply). Your financial adviser will be responsible for furnishing all necessary documents to Natixis Funds. Your financial adviser may charge you for these services. Your financial adviser must receive your request in proper form before the close of regular trading on the NYSE for you to receive that day’s NAV.

Through a broker-dealer (certain restrictions may apply). You may purchase shares of the Fund through a broker-dealer that has been approved by the Distributor. Your broker-dealer may charge you a fee for effecting such transactions. Your broker-dealer must receive your request in proper form before the close of regular trading on the NYSE for you to receive that day’s NAV.

Directly from the Fund. Natixis Funds’ transfer agent must receive your purchase request in proper form before the close of regular trading on the NYSE in order for you to receive that day’s NAV.

A medallion signature guarantee may be required to add this option.

Minimum Investment Requirements for the Fund and each share class are described in the section “Purchase and Sale of Fund Shares.”

Minimum Balance Policy

In order to address the relatively higher costs of servicing smaller fund positions, on an annual basis the Fund may close an account and send the account holder the proceeds if the account falls below $500. The valuation of account balances for this purpose and liquidation itself generally occur during October of each calendar year, although they may occur at another date in the year.

Certain accounts, such as accounts using the Natixis Funds’ prototype document (including IRAs, Keogh Plans, 403(b)(7) plans and Coverdell Education Savings Accounts), accounts associated with fee-based programs (such as wrap programs), trust networked accounts, accounts initially funded within six months of the liquidation date, certain retirement accounts, or accounts that fall below the minimum as a result of an automatic conversion of Class C to Class A shares, are excluded from the liquidation.

Due to operational limitations, the Fund’s ability to apply the Minimum Balance Policy to shareholder accounts held through an intermediary in an omnibus fashion may be limited. The Fund may work with these intermediaries to enforce the Minimum Balance Policy on these accounts as can best be applied per

the timing and constraints of the intermediaries’ account recordkeeping systems. For information about the policy for Class N shares, see the section “Purchase and Sale of Fund Shares” in the Fund summary.

Accounts held through certain financial intermediaries that have entered into special arrangements with the Distributor may be subject to a different minimum balance policy than the one described above. Please see Appendix A to the Prospectus for more information regarding the minimum balance policies of specific financial intermediaries, which may differ from those disclosed elsewhere in the Prospectus or in the SAI. Consult your financial intermediary for additional information regarding the minimum balance policy applicable to your investment.

Certain Retirement Plans

Natixis Funds defines “Certain Retirement Plans” as it relates to load waivers, share class eligibility, and account minimums as follows:

Certain Retirement Plans includes 401(k) plans, 457 plans, 401(a) plans (including profit-sharing and money purchase pension plans), 403(b) and 403(b)(7) plans, defined benefit plans, non-qualified deferred compensation plans, Taft Hartley multi-employer plans and retiree health benefit plans. The accounts must be plan level omnibus accounts to qualify.

Certain Retirement Plans does not include individual retirement plan accounts such as IRAs, SIMPLE, SEP, SARSEP, Roth IRA, etc. Any retirement plan accounts registered in the name of a participant would not qualify.

How to Redeem Shares

You can redeem shares of the Fund directly from the Fund on any day on which the NYSE is open for business. The information below details the various ways you can redeem shares of the Fund. Except as noted below and in the “Selling Restrictions” section of this Prospectus, the Fund typically expects to pay out redemption proceeds on the next business day after a redemption request is received in good order. The information below also notes certain fees that may be charged by the Fund, its agents, your bank or your financial representative in connection to your redemption request. The Fund does not currently impose any redemption charge other than the CDSC imposed by the Fund’s distributor, as described in the “How Sales Charges are Calculated” section of this Prospectus. The Fund’s Board of Trustees reserves the right to impose additional charges at any time.

The Fund may fund a redemption request from various sources, including sales of portfolio securities, holdings of cash or cash equivalents, and borrowings from banks (including overdrafts from the Fund’s custodian bank and/or under the Fund’s line of credit, which is shared across certain other Natixis Funds and Loomis Sayles Funds). The Fund typically will redeem shares for cash; however, as described in more detail below, the Fund reserves the right to pay the redemption price wholly or partly in-kind (i.e., in portfolio securities rather than cash), if the Fund’s Adviser determines it to be advisable and in the best interest of shareholders. If a shareholder receives a distribution in-kind, the shareholder will bear the market risk associated with the distributed securities and would incur brokerage or other charges in converting the securities to cash.

Because large redemptions are likely to require liquidation by the Fund of portfolio holdings, payment for large redemptions may be delayed for up to seven days to provide for orderly liquidation of such holdings. Under unusual circumstances, the Fund may suspend redemptions or postpone payment for more than seven days as permitted by the SEC.

Redemptions totaling more than $100,000 from a single fund/account cannot be processed on the same day unless the proceeds of the redemption are sent via pre-established banking information on the account. Please see the section “STAMP2000 Medallion Signature Guarantee” for details.

Generally, for expedited payment of redemption proceeds, a transaction fee of $5.50 for wire transfers, $50 for international wire transfers or $36.00 for overnight delivery will be charged. These fees are subject to change.

Redemptions through your financial adviser. Your financial adviser must receive your request in proper form before the close of regular trading on the NYSE for you to receive that day’s NAV. Your financial adviser will be responsible for furnishing all necessary documents to Natixis Funds on a timely basis and may charge you for his or her services.

Redemptions through your broker-dealer. You may redeem shares of the Fund through a broker-dealer that has been approved by the Distributor, which can be contacted at 888 Boylston Street, Suite 800, Boston, MA 02199-8197. Your broker-dealer may charge you a fee for effecting such transaction. Your broker-dealer must receive your request in proper form before the close of regular trading on the NYSE for you to receive that day’s NAV. Your redemptions generally will be wired to your broker-dealer on the first business day after your request is received in good order.

Redemptions directly to the Fund. Natixis Funds’ transfer agent must receive your redemption request in proper form before the close of regular trading on the NYSE in order for you to receive that day’s NAV. Your redemptions generally will be sent to you on the first business day after your request is received in good order, although it may take longer.

You may make redemptions directly from the Fund in several ways:

By mail. Send a signed letter of instruction that includes the name of the Fund, the exact name(s) in which the shares are registered, your address, telephone number, account number and the number of shares or dollar amount to be redeemed to the following address:

Regular Mail
Natixis Funds
P.O. Box 219579
Kansas City, MO 64121-9579

Overnight Mail
Natixis Funds
330 West 9th Street
Kansas City, MO 64105-1514

All owners of shares must sign the written request in the exact names in which the shares are registered. The owners should indicate any special capacity in which they are signing (such as trustee or custodian or on behalf of a partnership, corporation or other entity).

By exchange. You may sell some or all of your shares of the Fund and use the proceeds to buy shares of the same class of another fund by sending a signed letter of instruction to Natixis Funds, by calling Natixis Funds at 800-225-5478 or by accessing your account online at www.im.natixis.com.

By internet. If you have established a user name and password and you have established the electronic transfer privilege, you can redeem shares through your online account at www.im.natixis.com. If you have not established a user name and password but you have established the electronic transfer privilege, go to www.im.natixis.com, click on “Account Access,” and follow the instructions.

By telephone. You may redeem shares by calling Natixis Funds at 800-225-5478. Proceeds from telephone redemption requests (less any applicable fees) can be wired to your bank account, sent electronically by ACH to your bank account or sent by check in the name of the registered owner(s) to the address of record. A wire fee will be deducted from your proceeds. Your bank may charge you a fee to receive the wire.

The telephone redemption privilege may be modified or terminated by the Fund without notice.

You may redeem by telephone to have a check sent to the address of record for the maximum amount of $100,000 per day from a single fund/account. For your protection, telephone or internet redemption requests will not be permitted if Natixis Funds has been notified of an address change or bank account information change for your account within the preceding 30 days. If you prefer, you can decline telephone redemption and transfer privileges by calling Natixis Funds at 800-225-5478.

Systematic Withdrawal Plan. If the value of your account is $10,000 or more, you can have periodic redemptions automatically paid to you or to someone you designate. Please call 800-225-5478 for more information or to set up a systematic withdrawal plan or visit www.im.natixis.com to obtain a Service Options Form.

In-Kind. Shares normally will be redeemed for cash upon receipt of a redemption request in good order, although the Fund reserves the right to pay the redemption price wholly or partly in-kind if the Fund’s Adviser determines it to be advisable and in the best interest of shareholders. For example, the Fund may pay a redemption in-kind under stressed market conditions or if the redemption amount is large.

You may also request an in-kind redemption of your shares by calling Natixis Funds at 800-225-5478. In-kind redemptions typically take several weeks to effectuate following a redemption request given the operational steps necessary to coordinate with the redeeming shareholder’s custodian. Typically, the redemption date is mutually-agreed upon by the Fund and the redeeming shareholder. The Fund is not required to pay a redemption in-kind even if requested and may in its discretion pay the redemption proceeds in cash.

Redemptions in-kind will generally, but not necessarily, result in a pro rata distribution of each security held in the Fund’s portfolio. If a shareholder receives a distribution in-kind, the shareholder will bear the market risk associated with the distributed securities and would incur brokerage or other charges in converting the securities to cash.

By wire. Before Natixis Funds can wire redemption proceeds (less any applicable fees) to your bank account, you must provide specific wire instructions to Natixis Funds in writing (see “STAMP2000 Medallion Signature Guarantee” below). A wire fee will be deducted from the proceeds of each wire. Your bank may charge you a fee to receive the wire.

By ACH. Before Natixis Funds can send redemptions through ACH, you must provide specific wiring instructions to Natixis Funds in writing (see “STAMP2000 Medallion Signature Guarantee” below). For ACH redemptions, proceeds will generally arrive at your bank within three business days.

STAMP2000 Medallion Signature Guarantee. You must have your signature guaranteed by a bank, broker-dealer or other financial institution that can issue a STAMP2000 Medallion Signature Guarantee for the following types of redemptions:

•	If you are selling more than $100,000 per day from a single fund/account and you are requesting the proceeds by check (this does not apply to IRA transfer of assets to new custodian).

•	If you are requesting that the proceeds check (of any amount) be made out to someone other than the registered owner(s) or sent to an address other than the address of record.

•	If the account registration or bank account information has changed within the past 30 days.

•	If you are instructing us to send the proceeds by check, wire or ACH to a bank not already active on the fund account.

The Fund will only accept STAMP2000 Medallion Signature Guarantees bearing the STAMP2000 Medallion imprint. The surety amount of the STAMP2000 medallion imprint must meet or exceed the amount on the request. Please note that a notary public cannot provide a STAMP2000 Medallion Signature Guarantee. This signature guarantee requirement may be waived by Natixis Funds in certain cases.

Exchanging or Converting Shares

In general, you may exchange shares of the Fund (excluding Class T shares) for shares of the same class of another Natixis Fund that offers such class of shares (see the sections “How to Purchase Shares” and “How to Redeem Shares”) without paying a sales charge or a CDSC, if applicable, subject to restrictions noted below. Class T shares of the Fund do not have exchange privileges. The exchange must be for at least the minimum to open an account (or the total NAV 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 $50 (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 U.S. 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. Class N shares are not eligible to be exchanged through the website or through the Natixis Funds Automated Voice Response System.

In certain circumstances, you may convert shares of your Fund from your current share class into another share class in the same Fund. A conversion is subject to the eligibility requirements of the share class of your Fund that you are converting into including investment minimum requirements. The conversion from one class of shares to another will be based on the respective NAVs of the separate share classes on the trade date for the conversion. Except as noted below, Class C shares will automatically convert to Class A shares after eight years. Generally, to be eligible to have your Class C shares automatically converted to Class A shares, the Fund or the financial intermediary through which you purchased your shares will need to have records verifying that your Class C shares have been held for eight years. Due to operational limitations at your financial intermediary, your ability to have your Class C shares automatically converted to Class A shares may be limited. Group retirement plans of certain financial intermediaries who hold Class C shares with the Fund in an omnibus account do not track participant level aging of shares and therefore these shares will not be eligible for an automatic conversion. Certain intermediaries may convert your Class C shares to Class A shares in accordance with a conversion schedule that may differ from the one described above. Please consult your financial representative for more information.

Any account with an outstanding CDSC liability will be assessed the CDSC before converting to the new share class. Any conversions into a class of shares with a front end sales charge will not be subject to an initial sales charge; however, future purchases may be subject to a sales charge, if applicable. Generally, a conversion between share classes of the same fund is a nontaxable event to the shareholder. All requests for conversions must follow the procedures set forth by the Distributor. The Fund reserves the right to refuse any conversion request. Due to operational limitations at your financial intermediary, your ability to convert share classes of the same fund or have your Class C shares automatically converted to Class A shares may be limited. Please consult your financial representative for more information.

In general, you may sell Class Y shares of any Natixis Fund and use the proceeds to purchase Class I shares in any Loomis Sayles Fund, subject to the eligibility requirements, including fund minimums, of the fund you are purchasing into.

Cost Basis Reporting. Upon the redemption or exchange of your shares in the Fund, or, if you purchased your shares through a broker-dealer or other financial intermediary, your financial intermediary will be required to provide you and the Internal Revenue Service (“IRS”) with cost basis and certain other related tax information about the Fund shares you redeemed or exchanged. The cost basis reporting requirement is effective for shares purchased, including through dividend reinvestment, on or after January 1, 2012. Please contact the Fund at 800-225-5478, visit im.natixis.com or consult your financial intermediary, as appropriate, for more information regarding available methods for cost basis reporting and how to select a particular method. Please also consult your tax adviser to determine which available cost basis method is best for you.

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, below investment grade securities or small capitalization securities), also may 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 under “How to Redeem Shares.”

Limits on Frequent Trading. Excessive trading activity in the Fund is measured by the number of round trip transactions in a shareholder’s account. A round trip is defined as (1) 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 same Fund; or (2) a redemption (including a redemption by exchange) out of the Fund followed by a purchase (including a purchase by exchange) of any amount into the same Fund. Two round trip transactions in the Fund within a rolling 90-day period is considered to be excessive and will constitute a violation of the Fund’s trading limitations. After the detection of a first violation, the Fund or the Distributor will issue the shareholder and/or his

or her financial intermediary, if any, a written warning. After the detection of a second violation (i.e., two more round trip transactions in the Fund within a rolling 90-day period), the Fund or the Distributor will restrict the shareholder from making subsequent purchases (including purchases by exchange) for 90 days. After the detection of a third violation, the Fund or the Distributor will permanently restrict the account and any other accounts under the shareholder’s control in any Natixis Fund or Loomis Sayles Fund from making subsequent purchases (including purchases by exchange). The above limits are applicable whether a shareholder holds 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 excessive and, at its discretion, the Fund and the Distributor may restrict or prohibit transactions by such identified shareholders or intermediaries.

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, at 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 the 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 the 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. Under certain circumstances, waivers to these conditions (including waivers to permit more frequent rebalancing) may be approved for programs that in the Fund’s opinion are not vehicles for market timing and are not likely to engage in abusive trading.

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 excessive, short-term trading activity, it may, at its discretion, request that the shareholder or financial intermediary stop such activities or refuse to process purchases or exchanges in the accounts. At its discretion, the Fund and the Distributor, as well as an adviser to the Fund may ban trading in an account if, in their judgment, a shareholder or financial intermediary has engaged in short-term transactions that, while not necessarily in violation of the Fund’s stated policies on frequent trading, are harmful to the Fund or its 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 the Fund and the Distributor to monitor trades that are placed by omnibus or other nominee accounts is severely limited in those instances in which the financial intermediary maintains the record of the 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 excessive short-term trading activity. If the Fund believes that a shareholder has engaged in 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 that 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 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:	When 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.


Restriction	Situation
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 or if it is advisable for the Fund to redeem in-kind, as determined in the sole discretion of the Adviser , or if requested by the redeeming shareholder and agreed to by the Fund.
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.

The Fund reserves the right to suspend account services or refuse transaction requests if the Fund receives notice of a dispute between registered owners or of the death of a registered owner or the Fund suspects a fraudulent act. If the Fund refuses a transaction request because it receives notice of a dispute, the transaction will be processed at the NAV next determined after the Fund receives notice that the dispute has been settled or a court order has been entered adjudicating the dispute. If the Fund determines that its suspicion of fraud or belief that a dispute existed was mistaken, the transaction will be processed as of the NAV next determined after the transaction request was first received in good order.

Certificates. Certificates will not be issued or honored for any class of shares.

Self-Servicing Your Account

Shareholders that hold their accounts directly with the Fund may use the following self-service options. Shareholders that hold Fund shares through a financial intermediary should consult their financial intermediary regarding any self-service options that they may offer.

Natixis Funds Automated Voice Response System. You have access to your account 24 hours a day by calling Natixis Funds’ Automated Voice Response System at 800-225-5478. You may review your account balance and Fund NAV, order duplicate statements, order duplicate tax forms, obtain distribution and performance information and obtain wiring instructions (certain restrictions may apply).

Restructuring and Liquidations

Investors should note that the Fund reserves the right to merge or reorganize at any time, or to cease operations or liquidate itself. At any time prior to the liquidation of the Fund, shareholders may redeem their shares of the Fund pursuant to the procedures set forth under “How to Redeem Shares.” The proceeds from any such redemption will be the NAV of the Fund’s shares. Shareholders may also exchange their shares, subject to investment minimums and other restrictions on exchanges as described under “Exchanging or Converting Shares.” For federal income tax purposes, an exchange of the Fund’s shares for shares of another Natixis Fund or Loomis Sayles Fund is generally treated as a sale on which a gain or loss may be recognized.

Retirement Accounts. Absent an instruction to the contrary prior to the liquidation date of the Fund, for shares of the Fund held using a Natixis Funds’ prototype document, in individual retirement accounts, in custodial accounts under a SEP, SIMPLE, SARSEP or 403(b) plan, or in certain other retirement accounts, the Distributor will exchange any shares remaining in the Fund on the liquidation date for shares of Loomis Sayles Limited Term Government and Agency Fund (or, if that fund is no longer in existence, then in shares of another comparable Natixis Fund or Loomis Sayles Fund) at NAV. Please refer to your plan documents or contact your plan administrator or plan sponsor to determine whether the preceding sentence applies to you.

How Fund Shares Are Priced

NAV is the price of one share of the Fund without a sales charge, and is calculated each business day using this formula:

The policies and procedures used to determine the NAV of Fund shares are summarized below:

•

A share’s NAV 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 NAV next calculated (plus or minus applicable sales charges as

described earlier in the Fund Summary) after your order is received by the transfer agent, SS&C Global Investor & Distribution Solutions, Inc. (“SS&C GIDS”) (formerly, DST Asset Manager Solutions, Inc.), (rather than when the order arrives at the P.O. box) “in good order” (meaning that the order is complete and contains all necessary information).¹

•

Requests received by the Fund after the NYSE closes will be processed based upon the NAV 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 prior to the NYSE market close (normally 4:00 p.m., Eastern time), the shareholder will receive that day’s NAV. Under limited circumstances, the Distributor may enter into contractual agreements pursuant to which orders received by your investment dealer before the Fund determines its NAV and transmitted to the transfer agent prior to market open on the next business day are processed at the NAV 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 NAV next determined after your investment dealer submits the order to the Fund.

•	If the Fund invests in foreign securities, it may have NAV changes on days when you cannot buy or sell its shares.

1	Please see the section “How to Purchase 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 send your order by mail as described in the sections “How to Purchase Shares” and “How to Redeem Shares.”

Fund securities and other investments for which market quotations are readily available, as outlined in the Fund’s policies and procedures, are valued at market value. The Fund may use independent pricing services to obtain market quotations and other valuation information, such as evaluated bids. Generally, Fund securities and other investments are valued as follows:

•

Equity securities (including shares of closed-end investment companies and exchange-traded funds (“ETFs”)), exchange traded notes, rights, and warrants — listed equity securities are valued at the last sale price quoted on the exchange where they are traded most extensively or, if there is no reported sale during the day, the closing bid quotation as reported by an independent pricing service. Securities traded on the NASDAQ Global Select Market, NASDAQ Global Market and NASDAQ Capital Market are valued at the NASDAQ Official Closing Price (“NOCP”), or if lacking an NOCP, at the most recent bid quotations on the applicable NASDAQ Market. Unlisted equity securities (except unlisted preferred equity securities discussed below) are valued at the last sale price quoted in the market where they are traded most extensively or, if there is no reported sale during the day, the closing bid quotation as reported by an independent pricing service. If there is no sale price or closing bid quotation available, unlisted equity securities will be valued using evaluated bids furnished by an independent pricing service, if available. In some foreign markets, an official close price and a last sale price may be available from the foreign exchange or market. In those cases, the official close price is used. Valuations based on information from foreign markets may be subject to the Fund’s fair value policies described below. If a right is not traded on any exchange, its value is based on the market value of the underlying security, less the cost to subscribe to the underlying security (e.g., to exercise the right), adjusted for the subscription ratio. If a warrant is not traded on any exchange, a price is obtained from a broker-dealer.

•

Debt securities and unlisted preferred equity securities — evaluated bids furnished to the Fund by an independent pricing service using market information, transactions for comparable securities and various relationships between securities, if available, or bid prices obtained from broker-dealers.

•	Senior Loans — bid prices supplied by an independent pricing service, if available, or bid prices obtained from broker-dealers.

•

Bilateral Swaps — bilateral credit default swaps are valued based on mid prices (between the bid price and the ask price) supplied by an independent pricing service. Bilateral interest rate swaps and bilateral standardized commodity and equity index total return swaps are valued based on prices supplied by an independent pricing service. If prices from an independent pricing service are not available, prices from a broker-dealer may be used.

•	Centrally Cleared Swaps — settlement prices of the clearinghouse on which the contracts were traded or prices obtained from broker-dealers.

•

Options — domestic exchange-traded index and single name equity options contracts (including options on ETFs) are valued at the mean of the National Best Bid and Offer quotations as determined by the Options Price Reporting Authority. Foreign exchange-traded single name equity options contracts are valued at the most recent settlement price. Options contracts on foreign indices are priced at the most recent settlement price. Options on futures contracts are valued using the current settlement price on the exchange on which, over time, they are traded most extensively. Other exchange-traded options are valued at the average of the closing bid and ask quotations on the exchange on which, over time, they are traded most extensively. Over-the-counter (“OTC”) currency options and swaptions are valued at mid prices (between the bid price and the ask price) supplied by an independent pricing service, if available. Other OTC options contracts (including currency options and swaptions not priced through an independent pricing service) are valued based on prices obtained from broker-dealers. Valuations based on information from foreign markets may be subject to the Fund’s fair value policies described below.

•	Futures — most recent settlement price on the exchange on which the Adviser believes that, over time, they are traded most extensively. Valuations based on information from foreign markets may be subject to the Fund’s fair value policies as described below.

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

Foreign denominated assets and liabilities are translated into U.S. dollars based upon foreign exchange rates supplied by an independent pricing service. Fund securities and other investments for which market quotations are not readily available are valued at fair value as determined in good faith by the Adviser. The Fund may also value securities and other investments at fair value in other circumstances such as when extraordinary events occur after the close of a foreign 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). When fair valuing its securities or other investments, the Fund may, among

other things, use modeling tools or other processes that may take into account factors such as securities or other market activity and/or significant events that occur after the close of the foreign market and before the time the Fund’s NAV is calculated. Fair value pricing may require subjective determinations about the value of a security, and fair values used to determine the Fund’s NAV 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. Valuations for securities traded in the OTC market may be based on factors such as market information, transactions for comparable securities, various relationships between securities or bid prices obtained from broker-dealers. Evaluated prices from an independent pricing service may require subjective determinations and may be different than actual market prices or prices provided by other pricing services. As of the date of this prospectus, the Adviser serves as the Fund’s valuation designee for purposes of compliance with Rule 2a-5 under the 1940 Act.

Trading in some of the portfolio securities or other investments of the Fund takes place in various markets outside the United States on days and at times other than when the NYSE is open for trading. Therefore, the calculation of the Fund’s NAV does not take place at the same time as the prices of many of its portfolio securities or other investments are determined, and the value of the Fund’s portfolio may change on days when the Fund is not open for business and its shares may not be purchased or redeemed.

Dividends and Distributions

The Fund generally distributes all or substantially all of its net investment income (other than capital gains) as dividends. The Fund expects to distribute dividends quarterly.

In addition, the Fund expects to distribute all or substantially all of its net realized long- and short-term capital gains annually (or, in the case of short-term capital gains, more frequently than annually if determined by the Fund to be in the best interest of shareholders), after applying any 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. The Fund’s distribution rate fluctuates over time for various reasons, and there can be no assurance that the Fund’s distributions will not decrease or that the Fund will make any distributions when scheduled.

Distributions will automatically be reinvested in shares of the same class of the distributing Fund at NAV 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 NAV 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 the 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;

•	Receive distributions from capital gains in cash while reinvesting distributions from dividends and interest 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 accounts held directly with the Fund, any cash distributions to be paid by check, in an amount of $10 or less, will instead be automatically reinvested in additional Fund shares. If a dividend or capital gain distribution check remains uncashed for six months and your account is still open, the Fund will reinvest the dividend or distribution in additional shares of the Fund promptly after making this determination and the check will be canceled. In addition, future dividends and capital gain distributions will be automatically reinvested in additional shares of the Fund unless you subsequently contact the Fund and request to receive distributions by check.

If you do not select an option when you open your account, all distributions will be reinvested.

Generally, 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-DIV to help you report the prior calendar year’s distributions on your U.S. federal income tax return. This information will also be reported to the IRS. Be sure to keep this Form 1099-DIV as a permanent record. A fee may be charged for any duplicate information requested.

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.

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

Unless otherwise noted, the discussion below, to the extent it describes shareholder-level tax consequences, pertains solely to taxable shareholders.

Taxation of Distributions from the Fund. For U.S. federal income tax purposes, distributions of investment income are generally taxable to Fund shareholders as ordinary income. Taxes on distributions of capital gains are determined by how long the Fund owned (or is deemed to have 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 that the Fund owned (or is deemed to have owned) for more than one year over net short-term capital losses from the sale of investments that the Fund owned (or is deemed to have owned) for one year or less, and that are properly reported by the Fund as capital gain

dividends (“Capital Gain Dividends”) generally will be taxable to a shareholder receiving such distributions as long-term capital gain includible in net capital gain and taxed to individuals at reduced rates. Distributions attributable to the excess of net short-term capital gains from the sale of investments that the Fund owned (or is deemed to have owned) for one year or less over net long-term capital losses from the sale of investments that the Fund owned (or is deemed to have owned) for more than one year, will be taxable as ordinary income.

Distributions of investment income properly reported by the Fund as derived from “qualified dividend income” will be taxed in the hands of individuals at the reduced rates applicable to net capital gain, provided that the 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 received by the Fund from foreign corporations that are not eligible for the benefits of a comprehensive income tax treaty with the U.S. (other than dividends paid on stock of such a foreign corporation that is readily tradable on an established securities market in the U.S.) will not be eligible for treatment as qualified dividend income.

A 3.8% Medicare contribution tax is imposed on the net investment income of certain individuals, trusts and estates to the extent their income exceeds certain threshold amounts. Net investment income generally includes for this purpose dividends, including any Capital Gain Dividends paid by the Fund, and net capital gains recognized on the sale, redemption, exchange or other taxable disposition of shares of the Fund.

Fund distributions are taxable whether shareholders receive them in cash or reinvest them in additional shares. In addition, 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 NAV reflects gains that are either unrealized or realized but not distributed.

Dividends and distributions declared by the Fund and payable to shareholders of record 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.

Distributions by the Fund to retirement plans and other investors that qualify for tax-advantaged treatment under U.S. federal income tax laws generally will not be taxable, although distributions by retirement plans to their participants may be taxable. Special tax rules apply to investments through such retirement plans. If your investment is through such a plan, you should consult your tax adviser to determine the suitability of the Fund as an investment through your plan and the tax treatment of distributions to you (including distributions of amounts attributable to an investment in the Fund) from the plan.

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 generally will result in recognition of gain or loss. Gain or loss, if any, recognized by a shareholder on a redemption, sale, exchange or other taxable disposition of Fund shares generally will be taxed as long-term capital gain or loss if the shareholder held the shares for more than one year, and as short-term capital gain or loss if the shareholder held the shares for one year or less, assuming in each case that the shareholder held the shares as capital assets. Short-term capital gains generally are taxed at the rates applicable to ordinary income. Any loss realized upon a disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any Capital Gain Dividends received by the shareholder with respect to the shares. The deductibility of capital losses is subject to limitations.

Taxation of Certain Fund Investments. The Fund’s investments in foreign securities may be subject to foreign withholding or other taxes. In that case, the Fund’s yield on those securities would be decreased. The Fund generally does not expect that shareholders will be entitled to claim a credit or deduction with respect to foreign taxes incurred by the Fund. In addition, the 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 to shareholders. Because the Fund invests in foreign securities, shareholders should consult their tax advisers about the consequences of their investments under foreign laws.

The Fund’s investments in certain debt obligations (such as those with “OID” or accrued market discount in each case, as defined in the SAI), 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 is not advantageous to do so, in order to satisfy the distribution requirements applicable to regulated investment companies under the Code. In addition, the Fund’s investments in derivatives may affect the amount, timing or character of distributions to shareholders. In particular, the Fund’s transactions in options or other derivatives or short sales may cause a larger portion of distributions to be taxable to shareholders as ordinary income than would be the case absent such transactions.

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 (including a shareholder who is neither a citizen nor a resident of the United States) if the shareholder does not furnish the Fund with certain information and certifications or is otherwise subject to backup withholding.

Please see the SAI for additional information on the U.S. 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 U.S. federal, state, local, foreign or other applicable taxes.
