The bar chart shows changes in the Fund’s performance from year to year for Class A shares. The table shows how the Fund’s average annual returns compare with the performance of a selected broad-based market index, the ICE BofA U.S. All Capital Securities Index, over various time periods. The ICE BofA U.S. All Capital Securities Index tracks the performance of fixed rate, U.S. dollar-denominated hybrid corporate and preferred securities publicly issued in the U.S. domestic market.In addition to the broad-based market index, the table shows performance of the ICE BofA Fixed Rate Preferred Securities Index and a linked blended benchmark consisting of 50% ICE BofA Fixed Rate Preferred Securities Index and 50% ICE BofA U.S. Capital Securities Index through December 31, 2016, by the blended benchmark consisting of 60% ICE BofA U.S. IG Institutional Capital Securities Index, 30% ICE BofA Core Fixed Rate Preferred Securities Index, and 10% Bloomberg Developed Market USD Contingent Capital Index from January 1, 2017 through December 31, 2018, by the blended benchmark consisting of 60% ICE BofA U.S. IG Institutional Capital Securities Index, 20% ICE BofA Core Fixed Rate Preferred Securities Index, and 20% Bloomberg Developed Market USD Contingent Capital Index from January 1, 2019 through March 31, 2022, and by the blended benchmark consisting of 55% ICE BofA U.S. IG Institutional Capital Securities Index, 20% ICE BofA Core Fixed Rate Preferred Securities Index, and 25% Bloomberg Developed Market USD Contingent Capital Index from April 1, 2022 through June 30, 2025. On March 11, 2025, the Fund’s Board of Directors approved a change to the Fund’s blended benchmark. Effective after the close of business on June 30, 2025, the blended benchmark consists of 65% ICE BofA U.S. Institutional Capital Securities Index, 10% ICE BofA Core Fixed Rate Preferred Securities Index, and 25% Bloomberg Developed Market USD Contingent Capital Index. The ICE BofA Fixed Rate Preferred Securities Index tracks the performance of fixed-rate U.S. dollar-denominated preferred securities issued in the U.S. domestic market. The ICE BofA U.S. Capital Securities Index is a subset of the ICE BofA U.S. Corporate Index including securities with deferrable coupons.

The Bloomberg Developed Market USD Contingent Capital Index includes hybrid capital securities in developed markets with explicit equity conversion or write down loss absorption mechanisms that are based on an issuer’s regulatory capital ratio or other explicit solvency-based triggers. The Advisor believes that these indexes, as compared to the broad-based market index, are comprised of securities that are more representative of the Fund’s investment strategy. Past performance (both before and after taxes) is not, however, an indication as to how the Fund may perform in the future. Updated performance information, including the Fund’s NAV per share, is available at www.cohenandsteers.com or by calling (800) 330-7348. The bar chart does not reflect the deduction of sales charges imposed on Class A shares; if these amounts were reflected, returns would be less than those shown. Absent any applicable fee waivers and/or expense limitation, performance would have been lower. The table following the bar chart reflects applicable sales charges, if any.
