Under normal circumstances, the Fund’s sub-adviser, Nuveen Asset Management, LLC (“Nuveen Asset Management”), invests at least 80% of the Fund’s assets in fixed-income securities whose principal value increases or decreases based on changes in the Consumer Price Index for All Urban Consumers (“CPI-U”), over the life of the security (“inflation-indexed bonds”). Typically, the Fund will invest in U.S. Treasury Inflation-Indexed Securities (“TIIS”). The Fund can also invest in (1) other inflation-indexed bonds issued or guaranteed by the U.S. Government or its agencies, by corporations and other U.S. domiciled issuers, as well as foreign governments, and (2) money market instruments or other short-term securities. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.

Like conventional bonds, inflation-indexed bonds generally pay interest at fixed intervals and return the principal at maturity. Unlike conventional bonds, an inflation-indexed bond’s principal or interest is adjusted periodically to reflect changes in a specified inflation index. Inflation-indexed bonds are designed to preserve purchasing power over the life of the bond while paying a “real” rate of interest (i.e., a return over and above the inflation rate). These bonds are generally issued at a fixed interest rate that is lower than that of conventional bonds of comparable maturity and quality, but they generally retain their value against inflation over time.

The principal amount of a TIIS bond is adjusted periodically for inflation using the CPI-U. Interest is paid twice a year. The interest rate is fixed, but the amount of each interest payment varies as the principal is adjusted for inflation. The principal amount of a TIIS instrument may diminish in times of deflation. However, the U.S. Treasury guarantees that the final principal payment at maturity is at least the original principal amount of the bond. The interest and principal components of the bonds may be “stripped” or sold separately. The Fund can buy or sell either component.

The Fund may also invest in inflation-indexed bonds issued or guaranteed by foreign governments and their agencies, as well as other foreign issuers. These investments are usually designed to track the inflation rate in the issuing country. Under most circumstances, the Fund’s investments in inflation-linked bonds of foreign issuers are generally less than 20% of its assets.

The Fund’s benchmark index is the Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) 1-10 Year Index (the “Index”). As of December 31, 2025, the duration of the Index was 4.48 years. Although the Fund may invest in fixed-income securities of any duration, typically, the Fund invests in corporate and foreign inflation-indexed bonds that are similar in duration and maturity to those of U.S. Government inflation-indexed bonds.

The Fund may purchase and sell futures, options, swaps, forwards and other fixed-income derivative instruments to carry out the Fund’s investment strategies. In particular, the Fund may purchase and sell interest rate futures to attempt to manage duration and/or certain risks. The Fund also may invest in any fixed-income securities provided that no more than 5% of its assets are invested in fixed-income securities rated below investment-grade.

Under normal circumstances, the Fund invests at least 80% of its assets in the securities of companies that are principally engaged in or related to the real estate industry (“real estate securities”), including those that own significant real estate assets, such as real estate investment trusts (“REITs”). The Fund will invest primarily in equity securities of such companies. The Fund is actively managed using a research-oriented process with a focus on cash flows, asset values and Nuveen Asset Management, LLC’s (“Nuveen Asset Management”) belief in management’s ability to increase shareholder value. The Fund does not invest directly in real estate. The Fund concentrates its investments in the real estate industry. From time to time, the Fund may also invest in debt securities of companies principally engaged in or related to the real estate industry. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.

An issuer is principally “engaged in” or principally “related to” the real estate industry if at least 50% of its assets, gross income or net profits are attributable to ownership, construction, management or sale of residential, commercial or industrial real estate, or to products or services related to the real estate industry. The Fund typically invests in securities issued by equity REITs (which directly own real estate), mortgage REITs (which make short-term construction or real estate development loans or invest in long-term mortgages or mortgage pools), real estate brokers and developers, homebuilders, companies that manage real estate and companies that own substantial amounts of real estate. Businesses related to the real estate industry include manufacturers and distributors of building supplies and financial institutions that make or service mortgage loans.

The Fund also may invest up to 15% of its assets in real estate securities of foreign issuers and up to 20% of its assets in equity (including preferred stock) and debt securities of issuers that are not engaged in or related to the real estate industry. The benchmark index for the Fund is the FTSE Nareit All Equity REITs Index.

Under normal market conditions, the Fund invests at least 80% of its assets in fixed-income securities of emerging market issuers or in instruments with economic characteristics similar to emerging market fixed-income securities. For these purposes, “fixed-income securities” include fixed-income securities of any type, including bonds and notes (such as corporate and government debt obligations), mortgage-backed securities, asset-backed securities, structured securities that generally pay fixed or variable rates of interest, and loans and loan participations; debt obligations issued at a discount from face value (i.e., that have an imputed rate of interest); non-interest-bearing debt securities (i.e., zero coupon bonds); and other non-equity securities that pay dividends. The Fund primarily invests in a broad range of sovereign, quasi-sovereign and corporate fixed-income securities rated B- or better but may also invest in fixed-income securities having a lower credit rating. The Fund does not rely exclusively on rating agencies when making investment decisions. Instead, the Fund’s sub-adviser, Nuveen Asset Management, LLC (“Nuveen Asset Management”), performs its own credit analysis, paying particular attention to economic trends and other market events. Country and individual issuer allocations are then overweighted or underweighted relative to the Fund’s benchmark index, the J.P. Morgan Emerging Markets Bond Index (EMBI) Global Diversified (“EMBI-GD Index”), when Nuveen Asset Management believes that the Fund can take advantage of what appear to be undervalued, overlooked or misunderstood issuers that offer the potential to boost returns above that of the index. Fund holdings may be denominated in U.S. dollars or non-U.S. dollar currencies, including emerging market currencies. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.

The Fund considers an “emerging market security” to be a security that is principally traded on a securities exchange of an emerging market or that is

issued by an issuer that is located or has primary operations in an emerging market. The Fund generally defines an “emerging market” as any of the countries or markets represented in the Fund’s benchmark index, the EMBI-GD Index, or any other country or market with similar emerging characteristics.

The Fund may also engage in relative value trading, a strategy in which the Fund reallocates assets across different countries, currencies, sectors and maturities. Relative value trading is designed to enhance the Fund’s returns but increases the Fund’s portfolio turnover rate.

The Fund may purchase and sell futures, options, swaps and other fixed-income derivative instruments to carry out the Fund’s investment strategies.

Under normal market conditions, the Fund invests at least 80% of its assets in fixed-income investments of foreign issuers and derivative instruments, including those used to manage currency risk. For these purposes, “fixed-income investments” include fixed-income securities of any type, including bonds and notes (such as corporate and government debt obligations), mortgage-backed securities, asset-backed securities, structured securities that generally pay fixed or variable rates of interest, and loans and loan participations; debt obligations issued at a discount from face value (i.e., that have an imputed rate of interest); non-interest-bearing debt securities (i.e., zero coupon bonds); and other non-equity securities that pay dividends. The Fund primarily invests in a broad range of investment-grade sovereign, quasi-sovereign and corporate fixed-income investments. The Fund may also invest in other fixed-income securities, including those of non-investment-grade quality (usually called “high-yield” or “junk bonds”). Securities of non-investment-grade quality are speculative in nature. The Fund does not rely exclusively on rating agencies when making investment decisions. Instead, the Fund’s sub-adviser, Nuveen Asset Management, LLC (“Nuveen Asset Management”), performs its own credit analysis, paying particular attention to economic trends and other market events. Country and individual issuer allocations are then overweighted or underweighted relative to the Fund’s benchmark index, the Bloomberg Global Aggregate ex-USD Index (Hedged) (the “Index”), when Nuveen Asset Management believes that the Fund can take advantage of what appear to be undervalued, overlooked or misunderstood issuers that offer the potential to boost returns above that of the Index. Fund holdings may be denominated in U.S. dollars or non-U.S. dollar currencies, including emerging market currencies. Under normal market conditions, the Fund will seek to hedge to the U.S. dollar approximately 80% of the Fund’s total exposure to investments denominated in currencies other than the U.S. dollar (on a net assets basis). Such hedging is intended to manage the

currency risk associated with investment in bonds denominated in currencies other than the U.S. dollar. The Fund may invest in fixed-income securities of any maturity or duration. As of December 31, 2025, the duration of the Index was 6.69 years. “Duration” is a measure of volatility in the price of a bond in response to a change in prevailing interest rates, with a longer duration indicating more volatility. The Fund considers investments of foreign issuers to generally include one or more of the following: (1) companies whose securities are principally traded outside of the United States, (2) companies having their principal business operations outside of the United States, (3) companies organized outside of the United States, and (4) foreign governments and agencies or instrumentalities of foreign governments. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes. Derivative instruments, including those used to manage currency risk, are included as assets of the Fund for the purposes of the Fund’s 80% policy.

The Fund may also engage in relative value trading, a strategy in which the Fund reallocates assets across different countries, currencies, sectors and maturities. While this strategy is designed to enhance the Fund’s returns, it may also increase the Fund’s portfolio turnover rate. In addition, an increase in interest rates as well as other factors contributing to market volatility could lead to increased portfolio turnover.

The Fund may purchase and sell futures, options, swaps and other fixed-income derivative instruments to carry out the Fund’s investment strategies. In particular, the Fund may utilize forward currency contracts and currency-related futures contracts and swap agreements to manage currency risk.

The Fund may also seek exposure to Regulation S fixed-income securities through investment in a Cayman Islands exempted company that is wholly owned and controlled by the Fund (the “Regulation S Subsidiary”). A Cayman Islands exempted company is a corporate entity established under the laws of the Cayman Islands for the purpose of conducting business mainly outside the Cayman Islands. Regulation S fixed-income securities are debt securities of U.S. and non-U.S. issuers that are issued through private placement offerings without registration with the Securities and Exchange Commission (“SEC”) pursuant to Regulation S under the Securities Act of 1933. These may include sovereign or quasi-sovereign bonds, corporate bonds and structured notes issued pursuant to Regulation S. The Regulation S Subsidiary is advised by Nuveen Asset Management and has the same investment objective as the Fund, except that the Regulation S Subsidiary may invest without limitation in Regulation S securities.

The Fund may also seek exposure to certain bonds or fixed-income securities that are sold subject to selling restrictions under the Tax Equity and Fiscal Responsibility Act of 1982 (“TEFRA”), which generally restricts the purchase of such bonds to non-U.S. persons (as defined for applicable U.S. federal income tax purposes) (“TEFRA Bonds”) through investment of up to 25% of its total

assets in a separate Cayman Islands exempted company that is wholly owned and controlled by the Fund (the “TEFRA Bond Subsidiary”). These may include sovereign or quasi-sovereign bonds, corporate bonds and structured notes issued pursuant to TEFRA. The TEFRA Bond Subsidiary is advised by Nuveen Asset Management and has the same investment objective as the Fund, except that the TEFRA Bond Subsidiary may invest without limitation in TEFRA Bonds.
