      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. To obtain a prospectus and for other
