The investment seeks capital appreciation; current income is a secondary objective. The fund normally invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in the equity securities of U.S. and non-U.S. infrastructure-related issuers. The adviser maintains no less than 40% of the fund's net assets (plus the amount of any borrowings for investment purposes) in the securities of issuers located outside of the United States and will allocate its assets among issuers located in no fewer than three different countries, one of which may be the United States.
