Expense Narrative [Text Block]	The accompanying table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Shareholders should be aware that, as shown under “Management Fee” in the table below, the Fund pays no fees under its advisory agreement to the Fund’s advisor, Cohen & Steers Capital Management, Inc. (the “Advisor”). However, shares of the Fund are only offered to participants in separately managed account (“SMA”) programs (each, a “Program Participant”) who pay fees to program sponsors (each, a “Sponsor”) for the costs and expenses of the programs, including fees for investment advice, custody and portfolio execution, and to certain non-program SMA clients of the Advisor. When a Program Participant, alone or with his or her Sponsor, elects to allocate assets in an SMA to an investment strategy managed or advised by the Advisor, the Advisor typically receives a fee from the Sponsor for providing such advisory services to the SMA, including with respect to assets that may be invested in the Fund. In certain cases, a Program Participant will pay a fee for investment advice directly to the Advisor in its capacity as advisor to the Program Participant’s SMA. Similarly, non-program SMA clients will pay fees directly to the Advisor.
