2        SUMMARY PROSPECTUS — GOLDMAN SACHS SMALL/MID CAP GROWTH FUND

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 B, Class C, Institutional, Service, Class IR and/or Class R Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class B, Class C, Institutional, Service, Class IR and/or Class R 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 arrangement 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	$	680	$	984	$	1,310	$	2,230
Class B Shares
— Assuming complete redemption at end of period	$	713	$	989	$	1,391	$	2,384
— Assuming no redemption	$	213	$	689	$	1,191	$	2,384
Class C Shares
— Assuming complete redemption at end of period	$	313	$	689	$	1,191	$	2,573
— Assuming no redemption	$	213	$	689	$	1,191	$	2,573
Institutional Shares	$	97	$	335	$	592	$	1,327
Service Shares	$	148	$	490	$	857	$	1,888
Class IR Shares	$	112	$	382	$	672	$	1,498
Class R Shares	$	163	$	536	$	935	$	2,050

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 August 31, 2012 was 51% 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 diversified portfolio of equity investments in small and mid-cap issuers with public stock market capitalizations (based upon shares available for trading on an unrestricted basis) within the range of the market capitalization of companies constituting the Russell 2500^® Growth Index at the time of investment. If the market capitalization of a company held by the Fund moves outside this range, the Fund may, but is not required to, sell the securities. As of November 30, 2012, the capitalization range of the Russell 2500^® Growth Index was between $29.73 million and $9.99 billion. The Fund seeks to achieve its investment objective by investing in equity investments that are considered by the Investment Adviser to be strategically positioned for long-term growth. Although the Fund invests primarily in publicly traded U.S. securities, it may invest up to 25% of its Net Assets in foreign securities, including issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies.

The Fund’s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to indicate a high-quality business with sustainable growth, including strong business franchises, favorable long-term prospects, and excellent management. The Investment Adviser will also consider valuation of companies when determining whether to buy and/or sell securities. The Investment Adviser may decide to sell a position for various reasons, including when a company’s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes, or when a company is deemed to be misallocating capital or a company no longer fits within the Fund’s definition of a small/ mid cap company. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund may invest up to 20% of its Net Assets in fixed income securities, such as government, corporate and bank debt obligations.

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.

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.

3        SUMMARY PROSPECTUS — GOLDMAN SACHS SMALL/MID CAP GROWTH FUND

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 investments in 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.

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.

PERFORMANCE

The bar chart below and table at right provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class B, Class C, Institutional, Service, Class IR and Class R Shares compare to those of a broad-based securities market index. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.goldmansachsfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the 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. 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: Steven M. Barry, Managing Director, Chief Investment Officer—Fundamental Equity, Chief Investment Officer—Growth Equity, has managed the Fund since 2005; and Jeffrey Rabinowitz, CFA, Managing Director, has managed the Fund since 2009.

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 and Class R 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.

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 or Class R 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.

Class B Shares are generally no longer available for purchase by current or prospective investors.

You may purchase and redeem (sell) shares of the Fund on any business day through certain brokers, 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.
