Closed-ended funds are CIUs with a limited number of holdings. Where the fund vehicle is a company, holdings can take the form of shares. New holdings are rarely issued after the fund is launched and are not normally redeemable until the fund liquidates. Typically an investor can acquire or dispose of holdings in a closed-ended fund by buying or selling them on a secondary market, from a market intermediary or other investor, rather than by dealing with the CIU itself.
