§ 3563. Moneys of the corporation. All moneys of the corporation from whatever source derived shall be paid to the treasurer of the corporation and shall be deposited forthwith in a bank or banks designated by the corporation. The moneys in such accounts shall be paid out on check of the treasurer upon requisition by such person or persons as the corporation may authorize to make such requisitions. All deposits of such moneys shall be secured by obligations of the United States or of the state or of any municipality of a market value equal at all times to the amount on deposit and all banks and trust companies are authorized to give such security for such deposits. To the extent practicable, consistent with the cash requirements of the corporation, all such moneys shall be deposited in interest bearing accounts. The corporation shall have power, notwithstanding the provisions of this section, to contract with the holders of any bonds as to the custody, collection, security, investment and payment of any moneys of the corporation or any moneys held in trust or otherwise for the payment of bonds or in any way to secure bonds, and carry out any such contract notwithstanding that such contract may be inconsistent with the provisions of this section. Moneys held in trust or otherwise for the payment of bonds or in any way to secure bonds and deposits of such moneys may be secured in the same manner as moneys of the corporation and all banks and trust companies are authorized to give such security for such deposits. Any moneys of the corporation not required for immediate use or disbursement may, at the discretion of the corporation, be invested in those obligations specified pursuant to the provisions of § 98-a of the state finance law. Subject to the provisions of any contract with bondholders and the approval of the comptroller, the corporation shall prescribe a system of accounts.
