You should have received proxy material electronically or in the mail concerning the special meeting of stockholders to be held on November 15, 2019.

Your vote is very important. A vote in favor of the reorganization of Global Income Builder with and into Cohen & Steers Infrastructure Fund could benefit stockholders of Global Income Builder by resulting in a lower total operating expense ratio and enhanced market liquidity for the combined Fund’s shares of common stock.
