Fund(s) shown may take short positions. A short position arises when the fund sells stock that it does not own but was borrowed in anticipation that the market price of the stock will decline. If the market price declines, the fund can replace the borrowed stock at a lower price and capture the value represented by the difference between the higher sale price and the lower replacement price. Conversely, if the price of the stock goes up after the fund borrows the stock, the fund will lose money because it will have to pay more to replace the borrowed stock than it received when it sold the stock short. Any loss will be increased by the amount of compensation, interest or dividends, and transaction costs the fund must pay to the lender of the borrowed security. In addition, because the fund's loss on a short sale stems from increases in the value of the stock sold short, the extent of such loss, like the price of the stock sold short, is theoretically unlimited. By contrast, a fund's loss on a long position arises from decreases in the value of the stock and therefore is limited by the fact that a stock's value cannot drop below zero. In addition, the fund may not be able to close out a short position at a particular time or price advantageous to the fund and there is some risk the lender of the stock sold short will terminate the loan at an inopportune time.
