Important Information

Closed-end funds are traded on the secondary market through one of the stock exchanges. A fund's investment return and principal value will fluctuate so that an investor's shares may be worth more or less than the original cost. Shares of closed-end funds may trade above (a premium) or below (a discount) the net asset value (NAV) of the fund's portfolio. There is no assurance that a fund will achieve its investment objective. Past performance does not guarantee future results.

The value at which a closed-end fund stock trades on a stock exchange is a function of external market factors that are not under the control of the Fund's Board or Investment Advisor. Closed-end fund shares may therefore trade at a premium or a discount to net asset value at any given time. Shareholders should be aware that a fund trading at a premium to net asset value may not be sustainable, and a fund's discount to net asset value can widen as well as narrow. Shareholders of a fund trading at a premium who participate in that fund's dividend reinvestment plan should note the reinvestment of distributions may occur at a premium to net asset value.
