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 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 March 31, 2026 was 24% of the average value of its portfolio.  

Principal Strategy

The Fund invests, under normal market conditions, at least 80% of its net assets plus any borrowings for investment purposes ("Net Assets") in fixed income securities issued by or on behalf of states, territories and possessions of the United States (including the District of Columbia) and the political subdivisions, agencies and instrumentalities thereof ("Municipal Securities"), the interest on which is exempt from regular federal income tax (i.e., excluded from gross income for federal income tax purposes). A fixed income security is a debt instrument issued by a company, government or other entity to borrow money. The issuer typically pays a fixed, variable, or floating rate of interest and must repay the amount borrowed, usually at the maturity of the security. The Fund may invest up to 100% of its Net Assets in private activity bonds, the interest on which (including the Fund's distributions of such interest) may be a preference item for purposes of the federal alternative minimum tax. 100% of the Fund's portfolio will be invested in U.S. dollar-denominated securities.

The Fund may invest up to 30% of its Net Assets in Municipal Securities that, at the time of purchase, are non-investment grade (commonly referred to as "junk bonds"). Non-investment grade securities are 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. The Fund may purchase the securities of issuers that are in default.

The Fund may also seek to obtain exposure to fixed income investments through investments in affiliated or unaffiliated investment companies, including exchange-traded funds ("ETFs").

The Fund may focus its investments in issuers within the same state or economic sector. The team uses a multi-faceted approach when evaluating whether to add or maintain exposure to any individual

position. A top-down approach is used to assess broad macro trends while a bottom-up analysis is used to determine relative value between individual securities. As part of the team's fundamental investment process, the team may integrate environmental, social and governance ("ESG") factors alongside traditional fundamental factors. In addition, individual securities will be considered for purchase or sale based on credit profile, risk, structure, pricing, and portfolio impact, as well as duration management, restructuring, opportunistic trading and tax loss harvesting. No one factor or consideration is determinative in the fundamental investment process.

Under normal interest rate conditions, the Fund's duration is expected to range between two and eight years. (Historically, over the last five years, the duration of the Bloomberg Municipal Bond 1-10 Year Blend Index has been between approximately 3.81 and 4.30 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 years 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.

The Investment Adviser measures the Fund's performance against the Bloomberg Municipal Bond 1-10 Year Blend Index. 

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. The Fund's principal risks are presented below in alphabetical order, and not in the order of importance or potential exposure.

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 or instruments may deteriorate rapidly, which may impair the Fund's liquidity and cause significant deterioration in net asset value ("NAV"). These risks are heightened in market environments where interest rates are rising as well as in connection with the Fund's investments in non-investment grade fixed income securities.

Geographic and Sector Risk.  If the Fund invests a significant portion of its total assets in certain issuers within the same state, geographic region or economic sector, an adverse economic, business, political, environmental or other development affecting that state, region or sector may affect the value of the Fund's investments more than if its investments were not so focused.

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. Changing interest rates may have unpredictable effects on the markets, may result in heightened market volatility and may detract from Fund performance. In addition, changes in monetary policy may exacerbate the risks associated with changing interest rates. Funds with longer average portfolio durations will

generally be more sensitive to changes in interest rates than funds with a shorter average portfolio duration. 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, which may occur rapidly or unexpectedly, 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 or otherwise maintains 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.

Liquidity Risk.  The 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 the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, declining prices of the securities sold, an unusually high volume of redemption requests, or other reasons. To meet redemption requests, the 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 from fixed income funds may be higher than normal, potentially causing increased supply in the market due to selling activity. Redemptions by large shareholders may have a negative impact on the Fund's liquidity.

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, governments or countries and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Events such as war, military conflict, geopolitical disputes, acts of terrorism, social or political unrest, natural disasters, recessions, inflation, rapid interest rate changes, supply chain disruptions, tariffs and other restrictions on trade, sanctions or the spread of infectious illness or other public health threats, or the threat or potential of one or more such events and developments, could also significantly impact the Fund and its investments.

Municipal Securities Risk.  Municipal Securities are subject to credit/default risk, interest rate risk and certain additional risks. The Fund may be more sensitive to adverse economic, business, political, environmental or other 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). While interest earned on Municipal Securities is generally not subject to federal tax, any interest earned on taxable Municipal Securities is fully taxable at the federal level and may be subject to tax at the state level.

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. The Fund may purchase the securities of issuers that are in default.

Other Investment Companies Risk.  By investing in other investment companies (including ETFs) indirectly through the Fund, investors will incur a proportionate share of the expenses of the other investment companies held by the Fund (including operating costs and investment management fees) in addition to the fees regularly borne by the Fund. In addition, the Fund will be affected by the investment policies, practices and performance of such investment companies in direct proportion to the amount of assets the Fund invests therein. To the extent the Fund invests in ETFs, the Fund will invest only in ETFs sponsored by GSAM or its affiliates, unless GSAM determines, in its sole discretion, that no affiliated ETF is available to provide the desired exposure (for example, by sector, industry, credit quality, or duration). GSAM will consider investing in an unaffiliated ETF on behalf of the Fund only where no affiliated ETF is available to provide the desired exposure. For investments in affiliated ETFs, GSAM has agreed to waive a portion of its management fees in an amount equal to any management fees it earns as the investment adviser to the affiliated ETFs.

State/Territory Specific Risk. The Fund's investments in municipal obligations of issuers located in a particular state or U.S. territory may be adversely affected by political, economic and regulatory developments within that state or U.S. territory. Such developments may affect the financial condition of a state's or territory's political subdivisions, agencies, instrumentalities and public authorities and heighten the risks associated with investing in bonds issued by such parties, which could, in turn, adversely affect the Fund's income, NAV, liquidity, and/or ability to preserve or realize capital appreciation.

Tax Risk. Any proposed or actual changes in income tax rates or the tax-exempt status of interest income from Municipal Securities can significantly affect the demand for and supply, liquidity and marketability of Municipal Securities. Such changes may affect the Fund's net asset value and ability to acquire and dispose of Municipal Securities at desirable yield and price levels. 

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund's Institutional Shares from year to year; and (b) how the average annual total returns of the Fund's Class A, Class C, Institutional, Investor, Service and Class R6 Shares compare to those of a regulatorily required broad-based securities market index (Bloomberg U.S. Aggregate Bond Index) (the "Regulatory Benchmark") and the Bloomberg Municipal Bond 1-10 Year Blend Index (the "Performance Benchmark").
