The board may lend securities owned by the Fund to a borrower upon such terms and conditions as may be mutually agreed in writing. Such agreement shall provide that during the period of such loan the Fund shall retain the right to receive, or collect from the borrower, all dividends, interest rights, or any distributions to which the Fund would have otherwise been entitled. The borrower shall deposit with the Fund, as collateral for such loan, cash equal to the market value of the securities at the time the loan is made and shall increase the amount of collateral if and when the Fund requests an additional amount because of subsequent increased market value of the securities.
The period for which the securities may be loaned shall not exceed one year, and the loan agreement may specify earlier termination by either party upon mutually agreed conditions.
