Closed-end funds, unlike open-end funds, are not continuously offered. There is a one-time public offering and once issued, shares of closed-end funds are sold in the open market through a stock exchange and frequently trade at prices lower than their net asset value. Net asset value (NAV) is total assets less total liabilities divided by the number of common shares outstanding.

Please consider the fund's investment objectives, risks, charges and expenses carefully before investing. The prospectus contains this and other information about the fund and should be read carefully before you invest or send money.
