The performance data quoted represent past performance. Past performance is no guarantee of future results. The investment return and principal value of an investment will fluctuate and shares, if redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data quoted. Performance information current to the most recent month end can be obtained by visiting our website at cohenandsteers.com. Total return assumes the reinvestment of all dividends and distributions at prices obtained under the Fund’s dividend reinvestment plan. NAV returns reflect fee waivers and/or expense reimbursements, without which the returns would be lower. The performance table does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the sale of Fund shares.
