The Fund may invest up to 20% of its Net Assets in private activity bonds, the interest on which (including the Funds distributions of such interest) may be a preference item for purposes of the federal alternative minimum tax. 100% of the Funds portfolio will be invested in U.S. dollar-denominated securities. The Fund may invest up to 15% 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 Goldman Sachs Asset Management, L.P. (the Investment Adviser or GSAM) to be of comparable credit quality. The Fund may purchase the securities of issuers that are in default. The Fund may use derivatives instead of buying and selling fixed income securities directly to manage duration, to gain exposure to individual securities or to gain exposure to a credit or asset-backed index. The Funds investments in derivatives may include futures contracts (including interest rate futures and treasury futures), options (including options on futures contracts, swaps, bonds, and indexes), and swaps (including credit default, index, total return, and interest rate swaps). The Fund may also seek to obtain exposure to fixed income investments, such as municipal bonds and U.S. government securities, through investments in affiliated or unaffiliated investment companies, including exchange-traded funds (ETFs). 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 teams 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 Funds duration is expected to range between three and six years. Duration is a measure of a debt securitys 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 securitys market price. The Investment Adviser measures the Funds performance against the Bloomberg 1-15 Year Blend (1-17) Municipal Bond Index.
