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

²  The differences in the “Other Expenses” ratios across the share classes are the result of, among other things, contractual differences in the transfer agency fees and the effect of mathematical rounding on the daily accrual of certain expenses, particularly in respect of small share classes. The “Other Expenses” for Class R6 Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

³  The Total Annual Portfolio Operating Expenses do not correlate to the ratios of net and total expenses to average net assets provided in the Financial Highlights, which reflect the operating expenses of the Portfolio and do not include Acquired (underlying) Fund Fees and Expenses.

⁴  The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired (underlying) 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 Portfolio’s average daily net assets, through at least July 31,2016, and prior to such date, the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees. The expense limitation may be modified or terminated by the Investment Adviser at its discretion and without shareholder approval after such date, although the Investment Adviser does not presently intend to do so. The differences in the “Expense Limitation” ratios across the share classes are the result of the effect of mathematical rounding on the daily accrual of expense reimbursements, particularly in respect of small share classes.

2        SUMMARY PROSPECTUS — GOLDMAN SACHS BALANCED STRATEGY PORTFOLIO

EXPENSE EXAMPLE

This Example is intended to help you compare the cost of investing in the Portfolio 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 Portfolio 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 your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same (except that the Example incorporates the expense limitation 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	$	682	$	973	$	1,286	$	2,169
Class C Shares
— Assuming complete redemption at end of period	$	316	$	678	$	1,167	$	2,514
— Assuming no redemption	$	216	$	678	$	1,167	$	2,514
Institutional Shares	$	99	$	323	$	565	$	1,260
Service Shares	$	150	$	477	$	827	$	1,814
Class IR Shares	$	115	$	370	$	646	$	1,432
Class R Shares	$	165	$	523	$	905	$	1,977
Class R6 Shares	$	97	$	317	$	555	$	1,236

PORTFOLIO TURNOVER

The Portfolio does not pay transaction costs when it buys and sells shares of the Underlying Funds (as defined below). However, each Underlying 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 Underlying Fund and its shareholders, including the Portfolio, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in annual Portfolio operating expenses or in the expense example above, but are reflected in the Portfolio’s performance. The Portfolio’s portfolio turnover rate for the fiscal year ended December 31, 2014 was 38% of the average value of its portfolio.

PRINCIPAL STRATEGY

The Portfolio seeks to achieve its investment objective by investing in a combination of underlying funds that currently exist or that may become available for investment in the future for which Goldman Sachs Asset Management (“GSAM” or the “Investment Adviser”) or an affiliate now or in the future acts as investment adviser or principal underwriter (the “Underlying Funds”). Some of the Underlying Funds invest primarily in fixed income or money market instruments (the “Underlying Fixed Income Funds”), some of the Underlying Funds invest primarily in equity securities (the “Underlying Equity Funds”), and other Underlying Funds invest dynamically across equity, fixed income, commodity and other markets through a managed-volatility or trend-following approach (the “Underlying Dynamic Funds”).

Under normal conditions, the Portfolio seeks to achieve its investment objective by investing approximately 50% (which allocation could be increased by 30% or decreased by 25%) of its assets in Underlying Fixed Income Funds, approximately 15% (which allocation could be increased by 5% or decreased by 15%) of its assets in the Underlying Dynamic Funds, and approximately 35% (which allocation could be increased by 25% or decreased by 30%) of its assets in Underlying Equity Funds. The allocation will be measured at the time of rebalance. Generally, the Investment Adviser rebalances the Portfolio approximately monthly, but the Portfolio can be rebalanced more or less frequently at the discretion of the Investment Adviser. Moreover, the general rebalance frequency of the Portfolio may increase or decrease in accord with the Investment Adviser’s models and views, which evolve as part of its ongoing research program. Unless otherwise stated herein, the Portfolio’s investment in any of the Underlying Funds may exceed 25% of its assets. The Investment Adviser expects that the Portfolio will invest a relatively significant percentage of its fixed income allocation in the Goldman Sachs Global Income and Goldman Sachs Strategic Income Funds; a relatively significant percentage of its equity allocation in the Goldman Sachs Large Cap Growth Insights, Goldman Sachs Large Cap Value Insights and Goldman Sachs International Equity Insights Funds; and a relatively significant percentage of its dynamic allocation in the Goldman Sachs Dynamic Allocation Fund.

The Portfolio’s blended benchmark is the Balanced Strategy Composite Index, as discussed further under “Performance.”

THE PARTICULAR UNDERLYING FUNDS IN WHICH THE PORTFOLIO MAY INVEST, THE EQUITY/FIXED INCOME TARGETS AND RANGES AND INVESTMENTS IN EACH UNDERLYING FUND MAY BE CHANGED FROM TIME TO TIME WITHOUT SHAREHOLDER APPROVAL OR NOTICE.

PRINCIPAL RISKS OF THE PORTFOLIO

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

Expenses. By investing in the Underlying Funds indirectly through the Portfolio, the investor will incur not only a proportionate share of the expenses of the Underlying Funds held by the Portfolio (including operating costs and investment management fees), but also expenses of the Portfolio.

3        SUMMARY PROSPECTUS — GOLDMAN SACHS BALANCED STRATEGY PORTFOLIO

Investments in Affiliated Underlying Funds. The Investment Adviser will have the authority to select and substitute Underlying Funds. The Investment Adviser and/or its affiliates are compensated by the Portfolios and by the Underlying Funds for advisory and/or principal underwriting services provided. The Investment Adviser is subject to conflicts of interest in allocating Portfolio assets among the various Underlying Funds both because the fees payable to it and/or its affiliates by Underlying Funds differ and because the Investment Adviser and its affiliates are also responsible for managing the Underlying Funds. The portfolio managers may also be subject to conflicts of interest in allocating Portfolio assets among the various Underlying Funds because the Portfolio’s portfolio management team may also manage some of the Underlying Funds. The Trustees and officers of the Goldman Sachs Trust (the “Trust”) may also have conflicting interests in fulfilling their fiduciary duties to both the Portfolios and the Underlying Funds for which GSAM or its affiliates now or in the future serve as investment adviser or principal underwriter. In selecting actively managed Underlying Funds, the Investment Adviser generally expects to select affiliated investment companies without considering or canvassing the universe of unaffiliated investment companies available even though there may (or may not) be one or more unaffiliated investment companies that may be a more appropriate addition to the Portfolio. To the extent that an investment in an affiliated investment company is not available, including as the result of capacity constraints, only then will the Investment Adviser consider unaffiliated investment companies.

Investing in the Underlying Funds. The investments of the Portfolio are concentrated in the Underlying Funds, and the Portfolio’s investment performance is directly related to the investment performance of the Underlying Funds it holds. The ability of the Portfolio to meet its investment objective is directly related to the ability of the Underlying Funds to meet their objectives as well as the allocation among those Underlying Funds by the Investment Adviser.

Investments of the Underlying Funds. Because the Portfolio invests in the Underlying Funds, the Portfolio’s shareholders will be affected by the investment policies and practices of the Underlying Funds in direct proportion to the amount of assets the Portfolio allocates to those Underlying Funds. See the “Principal Risks of the Underlying Funds” below.

Large Shareholder Transactions Risk. The Portfolio may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Portfolio. Such large shareholder redemptions may cause the Portfolio to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Portfolio’s net asset value (“NAV”) and liquidity. Similarly, large purchases of Portfolio shares may adversely affect the Portfolio’s performance to the extent that the Portfolio 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 Portfolio’s current expenses being allocated over a smaller asset base, leading to an increase in the Portfolio’s expense ratio.

Temporary Investments. Although the Portfolios normally seek to remain substantially invested in the Underlying Funds, each Portfolio may invest a portion of its assets in high-quality, short-term debt obligations to maintain liquidity, to meet shareholder redemptions and for other short-term cash needs. For temporary defensive purposes during abnormal market or economic conditions, a Portfolio may invest without limitation in short-term obligations. When a Portfolio’s assets are invested in such investments, the Portfolio may not be achieving its investment objective.

PRINCIPAL RISKS OF THE UNDERLYING FUNDS

The target and actual asset allocation percentages, the selection of Underlying Funds and the investments in the Underlying Funds are subject to change. Such changes may cause the Portfolio to be subject to additional or different risks than the risks listed below.

The investment program of some of the Underlying Funds is speculative, entails substantial risks and includes alternative investment techniques not employed by traditional mutual funds. The investment techniques of some of the Underlying Funds (if they do not perform as designed) may increase the volatility of performance and the risk of investment loss, including the loss of the entire amount that is invested, and there can be no assurance that the investment objective of those Underlying Funds will be achieved. Moreover, certain investment techniques which certain Underlying Funds may employ in their investment programs can substantially increase the adverse impact to which those Underlying Funds’ investments may be subject. There is no assurance that the investment processes of those Underlying Funds will be successful, that the techniques utilized therein will be implemented successfully or that they are adequate for their intended uses, or that the discretionary element of the investment processes of those Underlying Funds will be exercised in a manner that is successful or that is not adverse to the Portfolio.

Absence of Regulation. Certain of the Underlying Funds engage in over-the-counter (“OTC”) transactions, which trade in a dealer network, rather than on an exchange. In general, there is less governmental regulation and supervision of transactions in the OTC markets than of transactions entered into on organized exchanges.

Call/Prepayment Risk. An issuer could exercise its right to pay principal on an obligation held by an Underlying Fund (such as a mortgage-backed security) earlier than expected. This may happen when there is a decline in interest rates, when credit spreads change, or when an issuer’s credit quality improves. Under these circumstances, the Underlying Fund may be unable to recoup all of its initial investment and will also suffer from having to reinvest in lower yielding securities.

Commodity Sector Risk. Exposure to the commodities markets may subject certain of the Underlying Funds to greater volatility than investments in more traditional securities. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or

4        SUMMARY PROSPECTUS — GOLDMAN SACHS BALANCED STRATEGY PORTFOLIO

commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. The prices of energy, industrial metals, precious metals, agriculture and livestock sector commodities may fluctuate widely due to factors such as changes in value, supply and demand and governmental regulatory policies. The commodity-linked investments in which certain of the Underlying Funds may enter into may involve companies in the financial services sector and events affecting the financial services sector may cause the Underlying Fund’s share value to fluctuate.

Counterparty Risk. Many of the protections afforded to cleared transactions, such as the security afforded by transacting through a clearinghouse, might not be available in connection with OTC transactions. Therefore, in those instances in which an Underlying Fund enters into OTC transactions, the Underlying Fund will be subject to the risk that its direct counterparty will not perform its obligations under the transactions and that the Underlying Fund will sustain losses.

Credit/Default Risk. An issuer or guarantor of fixed income securities held by an Underlying Fund (which may have low credit ratings) may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities may deteriorate rapidly, which may impair an Underlying Fund’s liquidity and cause significant deterioration in net asset value (“NAV”). These risks are more pronounced in connection with the Underlying Fund’s investments in non-investment grade fixed income securities.

Derivatives Risk. Loss may result from an Underlying Fund’s investments in forwards, options, futures, swaps, options on swaps, structured securities and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of the underlying instruments may produce disproportionate losses to an Underlying Fund. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations.

Expenses Risk. Because the Underlying Funds may invest in pooled investment vehicles (including investment companies and exchange-traded funds (“ETFs”), partnerships and Real Estate Investment Trusts (“REITs”), the investor will incur indirectly through the Portfolio a proportionate share of the expenses of the other pooled investment vehicles, partnerships and REITs held by the Underlying Fund (including operating costs and investment management fees), in addition to the expenses of the Underlying Fund.

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 Underlying Fund invests. Loss may also result from the imposition of exchange controls, sanctions, confiscations and other government restrictions by the United States or other governments, or from problems in 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 Underlying Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. To the extent the Underlying Fund also invests in securities of issuers located in emerging markets, these risks may be more pronounced.

Interest Rate Risk. When interest rates increase, fixed income securities or instruments held by an Underlying Fund will generally decline in value. Long-term fixed income securities or instruments will normally have more price volatility because of this risk than short-term fixed income securities or instruments.

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. An Underlying Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.

Large Shareholder Transactions Risk. An Underlying Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Underlying Fund. Such large shareholder redemptions may cause an Underlying Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Underlying Fund’s NAV and liquidity. Similarly, large purchases of Underlying Fund shares may adversely affect the Underlying Fund’s performance to the extent that the Underlying 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 an Underlying Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Underlying Fund’s expense ratio.

Leverage Risk. Borrowing and the use of derivatives may result in leverage and may make an Underlying Fund more volatile. The use of leverage may cause certain Underlying Funds to liquidate portfolio positions to satisfy their obligations or to meet asset segregation requirements when it may not be advantageous to do so. The use of leverage by an Underlying Fund can substantially increase the adverse impact to which the Underlying Fund may be subject.

Liquidity Risk. An Underlying Fund may make investments that are illiquid or that may become less liquid in response to market developments or adverse investor perceptions. Illiquid investments may be more difficult to value. Liquidity risk may also refer to the risk that an Underlying Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests, or other reasons. To meet redemption requests, an Underlying Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions

5        SUMMARY PROSPECTUS — GOLDMAN SACHS BALANCED STRATEGY PORTFOLIO

from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.

Loan-Related Investments Risk. In addition to risks generally associated with debt investments, loan-related investments such as loan participations and assignments are subject to other risks. Although a loan obligation may be fully collateralized at the time of acquisition, the collateral may decline in value, be relatively illiquid, or lose all or substantially all of its value subsequent to investment. Many loan investments are subject to legal or contractual restrictions on resale and may be relatively illiquid and difficult to value. There is less readily available, reliable information about most loan investments than is the case for many other types of securities. Substantial increases in interest rates may cause an increase in loan obligation defaults. With respect to loan participations, an Underlying Fund may not always have direct recourse against a borrower if the borrower fails to pay scheduled principal and/or interest; may be subject to greater delays, expenses and risks than if the Underlying Fund had purchased a direct obligation of the borrower; and may be regarded as the creditor of the agent lender (rather than the borrower), subjecting the Underlying Fund to the creditworthiness of that lender as well. The market for loan obligations may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Because transactions in many loans are subject to extended trade settlement periods, an Underlying Fund may not receive the proceeds from the sale of a loan for a period after the sale. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet an Underlying Fund’s redemption obligations for a period after the sale of the loans, and, as a result, the Underlying Fund may have to sell other investments or engage in borrowing transactions, such as borrowing from its credit facility, if necessary to raise cash to meet its obligations.

Senior loans hold the most senior position in the capital structure of a business entity, and are typically secured with specific collateral, but are nevertheless usually rated below investment grade. Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. Second lien loans generally have greater price volatility than senior loans and may be less liquid.

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 certain of the Underlying Funds 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 an Underlying Fund. Additionally, commonality of holdings across quantitative money managers may amplify losses.

Market Risk. The market value of the securities in which an Underlying 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.

Mortgage-Backed and Other Asset-Backed Securities Risk. Mortgage-related and other asset-backed securities are subject to certain additional risks, including “extension risk” (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and “prepayment risk” (i.e., in periods of declining interest rates, issuers may pay principal more quickly than expected, causing an Underlying Fund to reinvest proceeds at lower prevailing interest rates). Mortgage-backed securities offered by non-governmental issuers are subject to other risks as well, including failures of private issuers to meet their obligations and unexpectedly high rates of default on the mortgages backing the securities. Other asset-backed securities are subject to risks similar to those associated with Mortgage-backed securities, as well as risks associated with the nature and servicing of the assets backing the securities. Asset-backed securities may not have the benefit of a security interest in collateral comparable to that of mortgage assets, resulting in additional credit risk.

Municipal Securities Risk. Municipal securities are subject to call/prepayment risk, credit/default risk, extension risk, interest rate risk and certain additional risks. An Underlying Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of similar projects (such as those relating to education, health care, housing, transportation, and utilities), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds and moral obligation bonds). Municipalities continue to experience difficulties in the current economic and political environment.

Non-Diversification Risk. Certain of the Underlying Funds are non-diversified, meaning that they are permitted to invest a larger percentage of their assets in fewer issuers than “diversified” mutual funds. Thus, such an Underlying Fund may be more susceptible to adverse developments affecting any single issuer held in its portfolio, and may be more susceptible to greater losses because of these developments.

Non-Hedging Foreign Currency Trading Risk. An Underlying Fund may engage in forward foreign currency transactions for both hedging and non-hedging purposes. The Investment Adviser may purchase or sell foreign currencies through the use of forward contracts based on the Investment Adviser’s judgment regarding the direction of the market for a particular foreign currency or currencies. In pursuing this strategy, the Investment Adviser seeks to profit from anticipated movements in currency rates by establishing “long” and/or “short” positions in forward contracts on various foreign currencies. Foreign exchange rates can be extremely volatile and a variance in the degree of volatility of the market or in the direction of the market from the Investment Adviser’s expectations may produce significant losses to an Underlying Fund. Some of these transactions may also be subject to interest rate risk.

6        SUMMARY PROSPECTUS — GOLDMAN SACHS BALANCED STRATEGY PORTFOLIO

Non-Investment Grade Fixed Income Securities Risk. Non-investment grade fixed income securities and unrated securities of comparable credit quality (commonly known as “junk bonds”) are considered speculative and are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific issuer developments, interest rate sensitivity, negative perceptions of the junk bond markets generally and less liquidity.

Short Position Risk. An Underlying Fund may enter into a short position through a futures contract, an option or swap agreement or through short sales of any instrument that the Underlying Fund may purchase for investment. Taking short positions involves leverage of an Underlying Fund’s assets and presents various risks. If the value of the underlying instrument or market in which an Underlying Fund has taken a short position increases, then the Underlying Fund will incur a loss equal to the increase in value from the time that the short position was entered into plus any related interest payments or other fees. Taking short positions involves the risk that losses may be disproportionate, may exceed the amount invested and may be unlimited.

Small Cap Risk. Investments in 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.

Sovereign Default Risk. An issuer of non-U.S. sovereign debt, or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay the principal or interest when due. This may result from political or social factors, the general economic environment of a country or levels of foreign debt or foreign currency exchange rates.

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.

Subsidiary and Tax Risk. The Dynamic Allocation Fund, by investing in its wholly-owned subsidiary organized as a company under the laws of the Cayman Islands (the “DAF Subsidiary”), will be indirectly exposed to the risks associated with the DAF Subsidiary’s investments, which are similar to those that are permitted to be held by the Dynamic Allocation Fund. The Dynamic Allocation Fund is limited in the extent to which it may invest directly in commodity-linked swaps or certain other commodity-linked derivatives. The DAF Subsidiary primarily obtains its commodity exposure by investing in commodity-linked derivative instruments, which may include but are not limited to total return swaps, commodity (U.S. or foreign) futures and commodity-linked notes. There can be no assurance that the investment objective of the DAF Subsidiary will be achieved. Because the DAF Subsidiary is not registered under the Investment Company Act, it is not subject to all the investor protections thereof. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Dynamic Allocation Fund and/or the DAF Subsidiary to operate as described in its prospectus and could adversely affect the Dynamic Allocation Fund. The tax treatment of the Dynamic Allocation Fund’s commodity-linked investments may be adversely affected by future legislation, Treasury Regulations, and/or guidance issued by the Internal Revenue Service (the “IRS”) that could affect whether income from such investments is “qualifying income” under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), or otherwise affect the character, timing and/or amount of the Dynamic Allocation Fund’s taxable income for any gains and distributions made by the Fund.

Swaps Risk. In a standard “swap” transaction, two parties agree to exchange the returns, differentials in rates of return or some other amount earned or realized on the “notional amount” of predetermined investments or instruments, which may be adjusted for an interest factor. Swaps can involve greater risks than direct investment in securities, because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty’s defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). Swaps may also be considered illiquid. It may not be possible for an Underlying Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Treasury Inflation Protected Securities (“TIPS”) Risk. The value of TIPS generally fluctuates in response to inflationary concerns. As inflationary expectations increase, TIPS will become more attractive, because they protect future interest payments against inflation. Conversely, as inflationary concerns decrease, TIPS will become less attractive and less valuable.

U.S. Government Securities Risk. The U.S. government may not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. U.S. Government Securities issued by those agencies, instrumentalities and sponsored enterprises, including those issued by the Federal National Mortgage Association (“Fannie Mae”), Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal Home Loan Banks, are neither issued nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. The maximum potential liability of the issuers of some U.S. Government Securities held by an Underlying Fund may greatly exceed their current resources, including any legal right to support from the U.S. Treasury. It is possible that issuers of U.S. Government Securities will not have the funds to meet their payment obligations in the future.

PERFORMANCE

The bar chart and table below provide an indication of the risks of investing in the Portfolio by showing: (a) changes in the performance of the Portfolio’s Class A Shares from year to year; and (b) how the average annual total returns of the Portfolio’s Class A, Class C, Institutional, Service, Class IR, Class R and Class R6 Shares compare to those of certain broad-based securities market indices and to the Balanced Strategy Composite Index, a composite representation prepared by the Investment Adviser of the performance of the Portfolio’s asset classes weighted according to their respective weightings in the Portfolio’s target range. The Balanced Strategy Composite Index is comprised of the Barclays Global Aggregate Bond Index (Gross, USD, Hedged) (60%) and the Morgan Stanley Capital International (MSCI) All Country World Index (ACWI) (Net, USD, Unhedged) (the “MSCI^® ACWI Index”) (40%). The Portfolio’s past performance, before and after taxes, is not necessarily an indication of how the Portfolio will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling 800-621-2550 for Institutional and Service shareholders and 800-526-7384 for all other shareholders.

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.

* Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares is that of the Institutional Shares. Performance prior to July 31, 2015 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.

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 Portfolio 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 Portfolio (the “Investment Adviser” or “GSAM”).

Portfolio Managers: William Fallon, Ph.D., Managing Director, Chief Investment Officer of Quantitative Investment Strategies—Macro Alpha Strategies, has managed the Portfolio since 2009; James Park, Managing Director, has managed the Portfolio since 2014; Nicholas Chan, CFA, Vice President, has managed the Portfolio since 2006; and Edward J. Tostanoski III, Vice President, has managed the Portfolio since 2015.

BUYING AND SELLING PORTFOLIO 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.

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 Portfolio 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 Portfolio on any business day through certain banks, trust companies, brokers, dealers, investment advisers and other financial institutions (“Authorized Institutions”).

TAX INFORMATION

The Portfolio’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 arrangement.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL  INTERMEDIARIES

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