¹  A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

²  The Investment Adviser has agreed to (i) waive a portion of its management fees in order to achieve an effective net management rate of 0.81% as an annual percentage rate of average daily net assets of the Fund, and (ii) reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, shareholder meeting, litigation, indemnification and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. These arrangements will remain in effect through at least February 26, 2017, and prior to such date the Investment Adviser may not terminate the arrangements without the approval of the Board of Trustees.

EXPENSE 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.

This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Class IR, Class R and/or Class R6 Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Class IR, Class R and/or Class R6 Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). 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 A Shares	$	672	$	951	$	1,250	$	2,098
Class C Shares
— Assuming complete redemption at end of period	$	304	$	653	$	1,129	$	2,443
— Assuming no redemption	$	204	$	653	$	1,129	$	2,443
Institutional Shares	$	89	$	299	$	527	$	1,181
Service Shares	$	139	$	455	$	793	$	1,749
Class IR Shares	$	103	$	347	$	611	$	1,364
Class R Shares	$	155	$	501	$	872	$	1,914
Class R6 Shares	$	86	$	287	$	506	$	1,135

PORTFOLIO TURNOVER

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended October 31, 2015 was 154% of the average value of its portfolio.

PRINCIPAL STRATEGY

The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in a broadly diversified portfolio of equity investments in companies that are organized outside the United States or whose securities are principally traded outside the United States.

The portfolio management team uses two distinct strategies — a bottom-up stock selection strategy and a top-down country/ currency selection strategy — to manage the Fund.

The Fund invests in at least three foreign countries and may invest in the securities of issuers in emerging countries. The Fund seeks broad representation of large-cap and mid-cap issuers across major countries and sectors of the international economy, with some exposure to small-cap issuers.

The Fund uses a quantitative style of management, in combination with a qualitative overlay, that emphasizes fundamentally-based stock and country/currency selection, careful portfolio construction and efficient implementation. The Fund’s investments are selected using fundamental research and a variety of quantitative techniques based on certain investment themes, including, among others, Momentum, Valuation and Profitability. The Momentum theme seeks to predict drifts in stock prices caused by delayed investor reaction to company-specific information and information about related companies. The Valuation theme attempts to capture potential mispricings of securities, typically by comparing a measure of the company’s intrinsic value to its market value. The Profitability theme seeks to assess whether a company is earning more than its cost of capital. The Investment Adviser may, in its discretion, make changes to its quantitative techniques, or use other quantitative techniques that are based on the Investment Adviser’s proprietary research.

The Fund seeks to maximize its expected return, while maintaining risk, style and capitalization characteristics similar to the Morgan Stanley Capital International (“MSCI”) Europe, Australasia, Far East (“EAFE”) Standard Index (Net, USD, Unhedged), adjusted for the Investment Adviser’s country views. Additionally, the portfolio management team’s views of the relative attractiveness of countries and currencies are considered in allocating the Fund’s assets among countries. The MSCI EAFE Standard Index (Net, USD, Unhedged) is designed to measure equity market performance of the large and mid capitalization segments of developed markets, excluding the U.S. and Canada.

The Fund may also invest in fixed income securities that are considered to be cash equivalents.

The Fund’s benchmark index is the MSCI EAFE Standard Index (Net, USD, Unhedged).

PRINCIPAL RISKS OF THE FUND

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Foreign and Emerging Countries Risk. Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. Loss may also result from the imposition of exchange controls, sanctions, confiscations and other government restrictions by the United States and other governments, or from problems in

3        SUMMARY PROSPECTUS — GOLDMAN SACHS INTERNATIONAL EQUITY INSIGHTS FUND

registration, settlement or custody. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. These risks may be more pronounced in connection with the Fund’s investments in securities of issuers located in emerging countries.

Investment Style Risk. Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.

Large Shareholder Transactions Risk. The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Management Risk. A strategy used by the Investment Adviser may fail to produce the intended results. The Investment Adviser attempts to execute a complex strategy for the Fund using proprietary quantitative models. Investments selected using these models may perform differently than expected as a result of the factors used in the models, the weight placed on each factor, changes from the factors’ historical trends, and technical issues in the construction and implementation of the models (including, for example, data problems and/or software issues). There is no guarantee that the Investment Adviser’s use of these quantitative models will result in effective investment decisions for the Fund. Additionally, commonality of holdings across quantitative money managers may amplify losses.

Market Risk. The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Mid-Cap and Small-Cap Risk. Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.

Portfolio Turnover Rate Risk. A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by the Fund and its shareholders, and is also likely to result in short-term capital gains taxable to shareholders.

Stock Risk. Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

* Class R6 Shares commenced operations on July 31, 2015. Performance of the Class R6 Shares is that of the Institutional Shares. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had similar returns (because these share classes represent interests in the same portfolio of securities) that differed only to the extent that Class R6 Shares and Institutional Shares have different expenses.

^†  Calculated from September 1, 1997 to December 31, 2015.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Service and Class IR Shares, and returns for Class R and Class R6 Shares (which are offered exclusively to employee benefit plans), will vary. 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. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

PORTFOLIO MANAGEMENT

Goldman Sachs Asset Management, L.P. is the investment adviser for the Fund (the “Investment Adviser” or “GSAM”).

Portfolio Managers: William Fallon, Ph.D., Managing Director, Chief Investment Officer of Quantitative Investment Strategies—Macro Strategies, has managed the Fund since 2010; Len Ioffe, CFA, Managing Director and Senior Portfolio Manager, has managed the Fund since 1997; Osman Ali, CFA, Managing Director, has managed the Fund since 2013; James Park, Managing Director, has managed the Fund since 2012; and Takashi Suwabe, Managing Director, has managed the Fund since 2013.

BUYING AND SELLING FUND SHARES

The minimum initial investment for Class A and Class C Shares is, generally, $1,000. The minimum initial investment for Institutional Shares is, generally, $1,000,000 for individual or certain institutional investors, alone or in combination with other assets under the management of the Investment Adviser and its affiliates. There is no minimum for initial purchases of Class IR, Class R and Class R6 Shares. Those share classes with a minimum initial investment requirement do not impose it on certain employee benefit plans, and Institutional Shares do not impose it on certain investment advisers investing on behalf of other accounts.

5        SUMMARY PROSPECTUS — GOLDMAN SACHS INTERNATIONAL EQUITY INSIGHTS FUND

The minimum subsequent investment for Class A and Class C shareholders is $50, except for certain employee benefit plans, for which there is no minimum. There is no minimum subsequent investment for Institutional, Class IR, Class R or Class R6 shareholders.

The Fund does not impose minimum purchase requirements for initial or subsequent investments in Service Shares, although an Authorized Institution (as defined below) may impose such minimums and/or establish other requirements such as a minimum account balance.

You may purchase and redeem (sell) shares of the Fund on any business day through certain banks, trust companies, brokers, dealers, investment advisers and other financial institutions (“Authorized Institutions”).

TAX INFORMATION

The Fund’s distributions are taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account. Investments through tax-deferred arrangements may become taxable upon withdrawal from such arrangements.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL  INTERMEDIARIES

If you purchase the Fund through an Authorized Institution, the Fund and/or its related companies may pay the Authorized Institution for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the Authorized Institution and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your Authorized Institution’s website for more information.
