Securities loans are made to broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral consisting of U.S. government securities, cash or cash equivalents (negotiable certificates of deposit, bankers’ acceptances or letters of credit) maintained on a daily mark-to-market basis in an amount at least equal at all times to the market value of the securities lent. The borrower pays to the Fund, as the lender, an amount equal to any dividends or interest received on the securities lent. The Fund may invest only the cash collateral received in interest-bearing, short-term securities or receive a fee from the borrower. In the case of cash collateral, the Fund typically pays a rebate to the lender. Although voting rights or rights to consent with respect to the loaned securities pass to the borrower, the Fund, as the lender, retains the right to call the loans and obtain the return of the securities loaned at any time on reasonable notice, and it will do so in order that the securities may be voted by the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved. The Fund’s performance will continue to reflect changes in the value of the securities loaned and will also reflect the receipt of either interest, through investment of cash collateral by the Fund in permissible investments, or a fee, if the collateral is U.S. Government securities.

In addition, an unexpected or quick reversal of such measures could cause market downturns, disruptions, volatility and inflation, which could adversely affect the Fund’s investments. In addition, federal, state, and other governments, their regulatory agencies, or self-regulatory organizations may take actions that affect the regulation of the instruments in which the Fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the Fund itself is regulated. Such legislation or regulation could limit or
