2        SUMMARY PROSPECTUS — GOLDMAN SACHS SHORT DURATION INCOME 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.

The Example assumes that you invest $10,000 in Class A, Class C, Institutional, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. 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	$	229	$	416	$	617	$	1,199
Class C Shares
— Assuming complete redemption at end of period	$	186	$	469	$	841	$	1,886
— Assuming no redemption	$	121	$	469	$	841	$	1,886
Institutional Shares	$	46	$	162	$	288	$	657
Investor Shares	$	55	$	190	$	338	$	767
Class R Shares	$	106	$	348	$	609	$	1,356
Class R6 Shares	$	45	$	159	$	283	$	645
Class T Shares	$	329	$	513	$	713	$	1,289

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, 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 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 March 31, 2018 was 106% 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 U.S. or foreign fixed income securities. These fixed income securities include securities issued or guaranteed by the U.S. government, its agencies, instrumentalities or sponsored enterprises (“U.S. Government Securities”), corporate debt securities, collateralized loan obligations, agency and privately issued adjustable rate and fixed rate mortgage loans or other mortgage-related securities (“Mortgage-Backed Securities”), asset-backed securities, high yield non-investment grade fixed income securities (i.e., securities rated BB+, Ba1 or below by a nationally recognized statistical rating organization (“NRSRO”) or, if unrated, determined by the Investment Adviser to be of comparable credit quality), high yield floating rate loans (“Bank Loans”) and sovereign and corporate debt securities, and other instruments of issuers in emerging market countries (“emerging countries debt”). The Fund may also invest in fixed income securities issued by or on behalf of states, territories, and possessions of the United States (including the District of Columbia) (“Municipal Securities”) and may purchase securities of issuers in default. The Fund may seek to obtain exposure to these investments through investments in affiliated or unaffiliated investment companies including the Goldman Sachs High Yield Fund, Goldman Sachs Emerging Markets Debt Fund and Goldman Sachs Local Emerging Markets Debt Fund.

The Fund may not invest, in the aggregate, more than 20% of its total assets measured at the time of purchase (“Total Assets”) in (i) emerging countries debt and (ii) non-investment grade fixed income securities.

The Fund may engage in forward foreign currency transactions for both hedging and non-hedging purposes. The Fund may invest in obligations of domestic and foreign issuers that are denominated in currencies other than the U.S. dollar (and may also be denominated in a currency other than that associated with the issuer’s domicile).

The Fund also intends to invest in other derivative instruments, including (but not limited to) interest rate futures contracts, options (including options on futures contracts, swaps, bonds and indexes), swaps (including credit default, index, basis, total return, volatility and currency swaps) and other forward contracts. The Fund may use derivatives, instead of buying and selling debt directly, to manage duration, to gain exposure to certain securities or indexes, or to take short positions with respect to individual securities or indexes. The Fund may invest in derivatives that are not denominated in U.S. dollars.

Except as described above, the Fund invests in fixed income securities rated at least BBB- or Baa3 at the time of purchase. The Fund will deem a security to have the highest credit rating assigned to it from an NRSRO at the time of purchase, if more than one NRSRO rates the security. Unrated securities may be purchased by the Fund if they are determined by the Investment Adviser to be of comparable credit quality.

The Fund’s maximum target duration under normal interest rate conditions is expected to be approximately 3.5 years, and during the past five years ended June 30, 2018, the duration of the Goldman Sachs Short Duration Income Fund Composite Index ranged between 2.68 and 2.80 years. “Duration” is a measure of a debt security’s price sensitivity to changes in interest rates. The longer the duration of the Fund (or an individual debt security), the more sensitive its market price to changes in interest rates. For example, if market interest rates increase by 1%, the market price of a debt security with a positive duration of 3 will generally decrease by approximately 3%. Conversely, a 1% decline in market interest rates will generally result in an increase of approximately 3% of that security’s market price.

In pursuing its investment objective, the Fund uses the Goldman Sachs Short Duration Income Fund Composite Index, which is comprised of the Bloomberg Barclays U.S. 1-5 Year Corporate Bond Index (50%) and the Bloomberg Barclays U.S. 1-5 Year Government Bond Index (50%) (the “Index”) as its performance

3        SUMMARY PROSPECTUS — GOLDMAN SACHS SHORT DURATION INCOME FUND

benchmark, but the Fund will not attempt to replicate the Index. The Fund may, therefore, invest in securities that are not included in the Index.

GSAM’s Fixed Income Investing Philosophy:

Global fixed income markets are constantly evolving and are highly diverse—with a large number of countries, currencies, sectors, issuers and securities. We believe that inefficiencies in these complex markets cause bond prices to diverge from their fair value. To capitalize on these inefficiencies and generate consistent risk-adjusted performance, we believe it is critical to:

◾ Thoughtfully combine diversified sources of return by employing multiple strategies

◾ Take a global perspective to uncover relative value opportunities

◾ Employ focused specialist teams to identify short-term mis-pricings and incorporate long-term views

◾ Emphasize a risk-aware approach as we view risk management as both an offensive and defensive tool

◾ Build a strong team of skilled investors who excel on behalf of our clients

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.

Call/Prepayment Risk. An issuer could exercise its right to pay principal on an obligation held by the 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 Fund may be unable to recoup all of its initial investment and will also suffer from having to reinvest in lower-yielding securities.

Counterparty Risk. Many of the protections afforded to cleared transactions, such as the security afforded by transacting through a clearing house, might not be available in connection with over the counter (“OTC”) transactions. Therefore, in those instances in which the Fund enters into uncleared OTC transactions, the Fund will be subject to the risk that its direct counterparty will not perform its obligations under the transactions and that the Fund will sustain losses.

Credit/Default Risk. An issuer or guarantor of fixed income securities or instruments held by the 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 the Fund’s liquidity and cause significant deterioration in net asset value (“NAV”). These risks are more pronounced in connection with the Fund’s investments in non-investment grade fixed income securities.

Derivatives Risk. The Fund’s use of options, futures, forwards, swaps, options on swaps and other derivative instruments may result in losses. These instruments, which may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other instruments may be illiquid or less liquid, volatile, difficult to price and leveraged so that small changes in the value of underlying instruments may produce disproportionate losses to the Fund. Certain derivatives are also subject to counterparty risk which is the risk that the other party in the transaction will not fulfill its contractual obligation. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

Expenses Risk. By investing in pooled investment vehicles (including investment companies, exchange-traded funds and money market funds) indirectly through the Fund, the investor will incur not only a proportionate share of the expenses of the other pooled investment vehicles held by the Fund (including operating costs and investment management fees), but also expenses of the Fund.

Extension Risk. An issuer could exercise its right to pay principal on an obligation held by the Fund (such as a Mortgage-Backed Security) later than expected. This may happen when there is a rise in interest rates. Under these circumstances, the value of the obligation will decrease, and the Fund will also suffer from the inability to invest in higher-yielding securities.

Floating and Variable Rate Obligations Risk. For floating and variable rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark and the reset time for an interest payment of such an obligation, which could harm or benefit the Fund, depending on the interest rate environment or other circumstances. In a rising interest rate environment, for example, a floating or variable rate obligation that does not reset immediately would prevent the Fund from taking full advantage of rising interest rates in a timely manner. However, in a declining interest rate environment, the Fund may benefit from a lag due to an obligation’s interest rate payment not being immediately impacted by a decline in interest rates.

Certain floating and variable rate obligations have an interest rate floor feature, which prevents the interest rate payable by the security from dropping below a specified level as compared to a reference interest rate (the “reference rate”), such as LIBOR. Such a floor protects the Fund from losses resulting from a decrease in the reference rate below the specified level. However, if the reference rate is below the floor, there will be a lag between a rise in the reference rate and a rise in the interest rate payable by the obligation, and the Fund may not benefit from increasing interest rates for a significant amount of time.

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. The imposition of exchange controls, sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and other governments, or from problems in share registration, settlement or custody, may also result in losses. Foreign risk also involves

4        SUMMARY PROSPECTUS — GOLDMAN SACHS SHORT DURATION INCOME FUND

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. In addition, the Fund will be subject to the risk that 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 interest when due.

Interest Rate Risk. When interest rates increase, fixed income securities or instruments held by the 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. The risks associated with changing interest rates may have unpredictable effects on the markets and the Fund’s investments. Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund.

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 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.

Loan-Related Investments Risk. In addition to the 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, the 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 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 Fund to the creditworthiness of that lender as well. Investors in loans, such as the Fund, may not be entitled to rely on the anti-fraud protections of the federal securities laws, although they may be entitled to certain contractual remedies. 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, a 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 a Fund’s redemption obligations for a period after the sale of the loans, and, as a result, the 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.

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 the 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 insurers 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. The 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). Generally, municipalities continue to experience difficulties in the current economic and political environment.

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

5        SUMMARY PROSPECTUS — GOLDMAN SACHS SHORT DURATION INCOME FUND

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.

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 government 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 the 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.

* Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of Class R6 Shares shown in the table above is that of Institutional Shares, including since inception performance as of Institutional Shares’ inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

** As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has been adjusted to reflect the higher maximum sales charge (load) imposed on purchases of Class T Shares. Class A Shares had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class A Shares impose a lower maximum sales charge (load) on purchases.

The after–tax returns are for Class A Shares only. The after–tax returns for Class C, Institutional, Investor, Class R6 and Class T Shares 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.

7        SUMMARY PROSPECTUS — GOLDMAN SACHS SHORT DURATION INCOME FUND

PORTFOLIO MANAGEMENT

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

Portfolio Managers: Dave Fishman, Managing Director, Head of Global Liquidity Management, has managed the Fund since 2012; and John Olivo, Managing Director, Global Head of Short Duration, has managed the Fund since 2016.

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.
