one of the two classes of shares in a dual-purpose investment company. The capital shares entitle the owner to all appre- ciation (or depreciation) in value in the underlying portfolio in addition to all gains realized by trading in the portfolio. The other class of shares in a dual-purpose investment company are income shares, which receive all income generated by the portfolio. If the fund guarantees a minimum level of income payable to the income shareholders, it may be necessary to sell some securities in the portfolio if the existing securities do not provide a high enough level of dividends and interest. In this case, the value of the capital shares will fall.
