Notwithstanding the provisions of this Act or of any other law, all proceeds from the sale of the bonds of the Commission issued pursuant to this Act or pledged or assigned to or in trust for the benefit of the holder or holders thereof shall be deposited by the Chairman of the Commission in such bank or banks or trust company or trust companies as may be designated by the Commission, and all deposits of such moneys shall, if required by the Commission, be secured by direct or fully guaranteed obligations of the United States of America, of a market value equal at all times to the amount of the moneys on deposit. Such moneys shall be disbursed as may be directed by the Commission and in accordance with the terms of any agreements with the holder or holders of any bonds. This Section shall not be construed as limiting the power of the Commission to agree in connection with the issuance of any of its bonds as to the custody and disposition of the moneys received from the sale of the bonds or from the income and revenues pledged or assigned to or in trust for the benefit of the holder or holders thereof. In addition to the authority otherwise available to invest funds, the Commission may invest any of its funds in obligations the interest upon which is tax-exempt under the provision of Section 103 of the Internal Revenue Code of 1986, or any successor code or provision. When all of the bonds of the Commission have been paid or provision has been made for the payment thereof and when the Commission has determined that it has accumulated more funds than are necessary therefor, those surplus funds shall be paid into the Student Loan Fund established under Section 110.
