There is established in the Treasury a fund, to be known as the “Capitol Preservation Fund” (hereafter in this part referred to as the “fund”), which shall consist of (1) amounts deposited, and interest and proceeds credited, under subsection (d), (2) obligations obtained under subsection (e), and (3) all surcharges received by the Secretary of the Treasury from the sale of coins minted under the Bicentennial of the United States Congress Commemorative Coin Act.
The Commission shall deposit in the fund gifts of money and proceeds of transactions under section 2082 of this title. The Secretary of the Treasury shall credit to the fund the interest on, and the proceeds from sale or redemption of, obligations held in the fund. Disbursements from the fund shall be made on vouchers approved by the Commission and signed by the co-chairmen.
The Secretary of the Treasury shall invest any portion of the fund that, as determined by the Commission, is not required to meet current withdrawals. Each investment shall be made in an interest bearing obligation of the United States or an obligation guaranteed as to principal and interest by the United States that, as determined by the Commission has a maturity suitable for the fund. In carrying out this subsection, the Secretary may make such purchases, sales, and redemptions of obligations as may be approved by the Commission.
