| 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 for Class A shares. Because Class F shares are currently not available for purchase, and have therefore not commenced investment operations, no performance information is provided for this share class. The table shows how the Fund’s average annual returns compare with the performance of a selected broad-based market index, the MSCI EAFE Index (net), over various time periods. The MSCI EAFE Index (net) is an equity index which captures large- and mid-capitalization companies in developed market countries excluding the U.S. and Canada and is net of dividend withholding taxes.In addition to the broad-based market index, the table shows performance of the FTSE EPRA Nareit Developed ex-U.S. Real Estate Index (net), an unmanaged market-capitalization-weighted total return index, which consists of publicly traded equity REITs and listed property companies from developed markets excluding the U.S. and is net of dividend withholding taxes. 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. 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. |
