Keep in mind, dividends are not guaranteed. Closed-end funds, unlike open-end funds, are not continuously offered. There is a one-time public offering and once issued, common shares of closed-end funds are bought and 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.
