Performance Narrative [Text Block]	The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund’s performance from year to year. 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, the Fund’s broad based market 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 a blended benchmark (the “Blended Benchmark”). The Blended Benchmark is represented by the performance of 75% ICE BofA U.S. IG Institutional Capital Securities Index and 25% Bloomberg Developed Market USD Contingent Capital Index. The ICE BofA U.S. IG Institutional Capital Securities Index tracks the performance of U.S. dollar denominated investment grade hybrid capital corporate and preferred securities publicly issued in the U.S. domestic market. 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 this index, as compared to the broad-based market index, is 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.
