The Funds referenced above are closed-end funds, and closed-end funds do not continuously issue shares for sale as open-end mutual funds do. Since the initial public offering periods have closed, each Fund now trades in the secondary market. Investors wishing to buy or sell shares need to place orders through an intermediary or broker. The share price of a closed-end fund is based on the market's value.

Shares of closed-end investment companies frequently trade at a discount to their net asset value and initial offering price. The risk of loss due to this discount may be greater for initial investors expecting to sell their shares in a relatively short period after completion of the initial public offering.

Investments in the Funds are not appropriate for all investors and are not intended to be complete investment programs. The Funds are designed as a long-term investments and not as a trading vehicles.

Risk is inherent in all investing. Investing in any investment company security involves risk, including the risk that you may receive little or no return on your investment or even that you may lose part or all of your investment. Therefore, before investing in the common shares of a Fund, you should consider the risks as well as the other information in each Fund’s prospectus.
