Natixis Advisors, L.P. (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 0.60% and 0.65% of the Fund’s average daily net assets for Class N and Y shares, respectively, exclusive of brokerage expenses, interest expense, taxes, organizational and extraordinary expenses, such as litigation and indemnification expenses. This undertaking is in effect through May 31, 2021 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 the applicable expense limitation for Class N and Y shares. 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.

Fund Summary

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 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:


	1 year		3 years		5 years		10 years
Class N	$	61	$	1,346	$	2,600	$	5,601
Class Y	$	66	$	1,370	$	2,639	$	5,667

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 64% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies

The Fund employs an asset allocation strategy designed for investors planning to retire within a few years of the target year designated in the Fund’s name. The Fund allocates its assets among investments in affiliated underlying funds and separately managed segments that invest directly in securities. Through these allocations, the Fund provides exposure to a variety of asset classes including U.S. equity and fixed-income securities; non-U.S. equity and fixed-income securities, including emerging markets securities (which generally encompass securities offered by markets that are not included in the MSCI World Developed Markets Index); and U.S. government and/or agency securities. The Fund’s asset allocation will become more conservative over time by reducing its equity exposure and increasing its fixed-income exposure in accordance with a “glide path” until approximately 10 years following its target year. The Fund assumes a retirement age of 65 at the target year and is designed for investors who plan to withdraw the value of their account gradually after retirement.

The Fund follows a sustainable investing approach that aligns with environmental, social and governance (“ESG”) principles and values. Consistent with the Fund’s multi-disciplinary approach, the ESG strategies used by the Fund may vary across the Fund’s underlying funds and separately managed segments. For example, strategies may integrate ESG factors into fundamental analysis to pursue alpha and manage risk, or may use sustainable themes to identify investment opportunities. Certain ESG strategies may also seek to exclude specific types of investments.

A brief description of the underlying funds, separately managed segments and asset classes in which the Fund may invest from time to time as well as the Fund’s target allocations can be found in the “More About Goals and Strategies” section of the prospectus. Under normal circumstances, the Fund may deviate no more than plus or minus 10% from its target allocations. The Fund’s Adviser, Natixis Advisors, L.P. (“Natixis Advisors”), may modify the selection of underlying funds and separately managed segments for the Fund from time to time. Subject to the oversight of Natixis Advisors, one of the Fund’s Subadvisers, Wilshire Associates Incorporated (“Wilshire”), determines the Fund’s glide path and target allocations.

The following glide path represents the shifting of equity and fixed-income allocations over time and shows how the Fund’s asset mix becomes more conservative as the target date approaches and passes. This reflects individuals’ expected need for reduced market risks as retirement approaches and for low portfolio volatility after retirement. The Fund is a “through” target date fund. This means that the Fund is expected to reach its final allocations approximately 10 years past its target year.

Fund Summary

The Fund’s investments, whether directly through its separately managed segments or indirectly through investments in underlying funds, will generally include equity securities, such as common and preferred stocks, fixed-income investments, such as government bonds, investment grade corporate notes and bonds, zero-coupon bonds, securities issued pursuant to Rule 144A under the Securities Act of 1933 (“Rule 144A securities”), asset-backed securities and mortgage-related securities, and may also include derivative transactions, such as forward currency contracts, structured notes, futures transactions and swap transactions. The Fund may invest in securities of any market capitalization.

The Fund’s Board of Trustees may approve combining the Fund with other Natixis Sustainable Future Funds^® that have reached their final allocations if the Board determines that such combination would be in the best interest of such Funds’ shareholders.

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, including losses near, at, or after the target year. There is no guarantee that the Fund will provide adequate income at or after the target year. Because of the Fund’s investments in the underlying funds, the Fund will be subject to many of the risks below indirectly through its investments in the underlying funds rather than directly through investment in the actual securities themselves.

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.

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. 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 or Subadviser’s assessment of the prospects for a company’s growth is wrong, or if the Adviser’s or Subadviser’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 or Subadviser 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. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the

Fund Summary

issuer’s bonds generally take precedence over the claims of those who own preferred stock or common stock. Securities of real estate-related companies and REITs in which the Fund may invest may be considered equity securities, thus subjecting the Fund to the risks of investing in equity securities generally.

Sustainable Investment Style Risk: Because the Fund focuses on equity securities of companies that meet certain ESG criteria, bonds whose purpose is to finance projects with a positive environmental impact and other fixed-income securities that, in the opinion of the Adviser, present minimal ESG concerns, its universe of investments may be smaller than that of other funds and therefore the Fund may underperform the market as a whole if such investments underperform the market. The Fund may forgo opportunities to gain exposure to certain attractive companies, industries, sectors or countries and it may choose to sell a security when it might otherwise be disadvantageous to do so.

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, nationalization or confiscatory taxation, currency exchange restrictions, sanctions by other countries (such as the United States) and an issuer’s unwillingness or inability to make principal or interest payments on its obligations. Emerging markets companies may be smaller and have shorter operating histories than companies in developed markets.

Mortgage-Related and Asset-Backed Securities Risk: In addition to the risks associated with investments in fixed-income securities generally (for example, credit, liquidity and valuation risk), mortgage-related and asset-backed securities are subject to the risks of the mortgages and assets underlying the securities as well as prepayment risk, the risk that the securities may be prepaid and result in the reinvestment of the prepaid amounts in securities with lower yields than the prepaid obligations. Conversely, there is a risk that a rise in interest rates will extend the life of a mortgage-related or asset-backed security beyond the expected prepayment time, typically reducing the security’s value, which is called extension risk. The Fund also may incur a loss when there is a prepayment of securities that were purchased at a premium. The Fund’s investments in other asset-backed securities are subject to risks similar to those associated with mortgage-related securities, as well as additional risks associated with the nature of the assets and the servicing of those assets.

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

Credit/Counterparty Risk: Credit/counterparty risk is the risk that the issuer or the guarantor of a fixed-income security, or the counterparty to a derivatives or other transaction, will be unable or unwilling to make timely payments of interest or principal or to otherwise honor its obligations. The Fund will be subject to credit/counterparty risks with respect to the counterparties to its derivatives transactions. Many of the protections afforded to participants on organized exchanges, such as the performance guarantee given by a central clearing house, are not available in connection with over-the-counter (“OTC”) derivative transactions, such as foreign currency transactions. As a result, in instances when the Fund enters into OTC derivative transactions, the Fund will be subject to the risk that its counterparties will not perform their obligations under the transactions and that the Fund will sustain losses or be unable to realize gains. This risk will be heightened to the extent the Fund enters into derivative transactions with a single counterparty (or affiliated counterparties that are part of the same organization), causing the Fund to have significant exposure to such counterparty.

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 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.

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.

Derivatives Risk: The Fund will be exposed to derivatives risk primarily through its investments in the underlying funds. Derivative instruments (such as those in which the underlying funds may invest, including forward currency contracts, structured notes, futures transactions and swap transactions) are subject to changes in the value of the underlying assets or indices on which such instruments are based. There is no guarantee that an underlying fund’s use of derivatives will be effective or that suitable transactions will be available. Even a small investment in derivatives by an underlying fund may give rise to leverage risk and can have a significant impact on the underlying fund’s exposure to securities market values, interest rates or currency exchange rates. It is possible that an underlying fund’s liquid assets may be insufficient to support its obligations under its derivatives positions. The use of derivatives for other than hedging purposes may be considered a speculative activity, and involves greater risks than are involved in hedging. The use of derivatives by an underlying fund may cause the Fund to incur losses greater than those that would have occurred had derivatives not been used. An underlying fund’s use of derivatives, such as forward currency contracts, structured notes, futures transactions and swap transactions involves other risks, such as the credit/counterparty risk relating to the other party to a derivative contract (which is greater for forward currency contracts, swaps and other OTC derivatives), the risk of difficulties in pricing and valuation, the risk that changes in the value of a derivative may not correlate as expected with changes in the value of relevant assets, rates or indices, liquidity risk, allocation risk and the risk of losing more than the initial margin (if any) required to initiate derivatives positions. There is also the risk that an underlying fund may be unable to terminate or sell a derivatives position at an advantageous time or price. An underlying fund’s derivative counterparties may experience financial difficulties or otherwise be unwilling or unable to honor their obligations, possibly resulting in losses to the Fund.

Fund Summary

Inflation-Protected Securities Risk: Inflation-protected securities are subject to the risk that the rate of inflation will be lower than expected. Inflation-protected securities are intended to protect against inflation by adjusting the interest or principal payable on the security by an amount based upon an index intended to measure the rate of inflation. There can be no assurance that the relevant index will accurately measure the rate of inflation, in which case the securities may not work as intended.

Interest Rate Risk: Interest rate risk is the risk that the value of the Fund’s investments will fall if interest rates rise. Generally, the value of fixed-income securities rises when prevailing interest rates fall and falls when interest rates rise. Interest rate risk generally is greater for funds that invest in fixed-income securities with relatively longer durations than for funds that invest in fixed-income securities with shorter durations. Duration is a measure of the expected life of a fixed-income security that is used to determine the sensitivity of a security’s price to changes in interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration. The value of zero-coupon bonds may be more sensitive to fluctuations in interest rates than other fixed-income securities. In addition, an economic downturn or period of rising interest rates could adversely affect the market for these securities and reduce the Fund’s ability to sell them, negatively impacting the performance of the Fund. Potential future changes in government monetary policy may affect the level of interest rates.

Investments in Other Investment Companies Risk: The Fund will indirectly bear the management, service and other fees of any other investment companies, including exchange-traded funds, in which it invests in addition to its own expenses. The Fund is also indirectly exposed to the same risks as the underlying funds in proportion to the allocation of the Fund’s assets among the underlying funds.

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.

Leverage Risk: Use of derivative instruments by an underlying fund may involve leverage. Leverage is the risk associated with securities or practices that multiply small index, market or asset-price movements into larger changes in value. The use of leverage increases the impact of gains and losses on a fund’s returns, and may lead to significant losses if investments are not successful.

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. OTC derivatives are generally subject to greater liquidity risk as well. Liquidity issues may also make it difficult to value the Fund’s investments.

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.

Retirement Risk: The Fund is not a complete retirement program and there is no guarantee that an investment in the Fund will provide sufficient retirement income at or through retirement. Although the Fund will become more conservative over time (meaning that the Fund will allocate more of its assets to fixed-income investments than equity investments as it nears the target retirement date), the Fund will continue to be exposed to market/issuer risk and the share price of the Fund will fluctuate, even after the Fund reaches its most conservative allocation. This means that you could lose money by investing in the Fund, including losses near, at, or after the target retirement date. In addition, your risk tolerance may change over time, including in ways that do not correlate perfectly with the Fund’s glide path. Achieving your retirement goals will depend on many factors, including the amount you save and the period over which you do so.

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.

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 comparing the Fund’s one-year and life-of-fund performance with a broad measure of market performance. The Fund’s past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information is available online at im.natixis.com and/or by calling the Fund toll-free at 800-225-5478.

Fund Summary

Total Returns for Class N Shares


	Highest Quarterly Return: First Quarter 2019, 11.36% Lowest Quarterly Return: Fourth Quarter 2018, -11.64%

The Fund’s Class N shares total return year-to-date as of March 31, 2020 was -21.51%.


Average Annual Total Returns
(for the periods ended December 31, 2019)	Past 1 Year	Life of Fund (2/28/17)
Return Before Taxes	25.78%	12.68%
Return After Taxes on Distributions	23.12%	10.46%
Return After Taxes on Distributions and Sale of Fund Shares	16.50%	9.47%
S&P Target Date 2060+^® Index	24.73%	10.40%

The Fund did not have Class Y shares outstanding during the periods shown above. The returns of Class Y shares would have been substantially similar to the returns of the Fund’s Class N shares because they would have been invested in the same portfolio of securities and would only differ to the extent the Class N shares did not have the same expenses.

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.

Purchase and Sale of Fund Shares

Class N Shares

Class N shares of the Fund are subject to a $1,000,000 initial investment minimum. This minimum applies to accounts established via a transfer or any other transaction in which a new account is established. There is no initial investment minimum for Certain Retirement Plans and funds of funds that are distributed by Natixis Distribution, L.P. (the “Distributor”). Sub accounts held within an omnibus account, where the omnibus account has at least $1,000,000, are not required to meet the investment minimum. There is no subsequent investment minimum for these shares. In its sole discretion, the Distributor may waive the investment minimum requirement for accounts as to which the Distributor reasonably believes will have enough assets to exceed the investment minimum requirement within a relatively short period of time following the establishment date of such accounts in Class N. If, after two years, an account’s value does not exceed the investment minimum requirement, the Distributor and the Fund reserve the right to redeem such account.

Class Y Shares

Class Y shares are not currently available for purchase.

Class Y shares of the Fund are generally subject to a minimum initial investment of $100,000 and a minimum subsequent investment of $50, except there is no minimum initial or subsequent investment for:

• Fee Based Programs (such as wrap accounts) where an advisory fee is paid to the broker-dealer or other financial intermediary. Please consult your financial representative to determine if your fee based program is subject to additional or different conditions or fees.
• Certain Retirement Plans. Please consult your retirement plan administrator to determine if your retirement plan is subject to additional or different conditions or fees.
• Certain Individual Retirement Accounts if the amounts invested represent rollover distributions from investments by any of the retirement plans

• Clients of a Registered Investment Adviser where the Registered Investment Adviser receives an advisory, management or consulting fee.
• Fund Trustees, former Fund 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) and Natixis affiliate employee benefit plans.

At the discretion of Natixis Advisors, L.P., clients of Natixis Advisors, L.P. and its affiliates may purchase Class Y shares of the Fund below the stated minimums.

Due to operational limitations at your financial intermediary, certain fee based programs, retirement plans, individual retirement accounts and accounts of registered investment advisers may be subject to the investment minimums described above.

The Fund’s shares are available for purchase and are redeemable on any business day through your investment dealer, directly from the Fund by writing to the Fund at Natixis Funds, P.O. Box 219579, Kansas City, MO 64121-9579, by exchange, by wire, by internet at im.natixis.com (certain restrictions may apply), through the Automated Clearing House system, or, in the case of redemptions, by telephone at 800-225-5478 or by the Systematic Withdrawal Plan.

Tax Information

Fund distributions are generally taxable to you as ordinary income or capital gains, except for distributions to retirement plans and other investors that qualify for tax-advantaged treatment under U.S. federal income tax law generally. Investments in such tax-advantaged plans will generally be taxed only upon withdrawal of monies from the tax-advantaged arrangement.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of the Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
