N.Y. Pub. Auth. Law § 1199-KKK
All moneys of the authority from whatever source derived shall be paid to the treasurer and shall be deposited forthwith in one or more banks and/or trust companies in the state designated by the authority. The moneys in such accounts shall be paid out on checks of the treasurer upon requisition by the board or of such other person or persons as the authority may authorize to make such requisitions. All deposits of such moneys shall be secured by obligations of (or guaranteed by) the United States of America or of the state or of the county 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. Any moneys of the authority not required for immediate use or disbursement may, at the discretion of the authority, be invested in those obligations specified pursuant to the provisions of section ninety-eight-a of the state finance law. The authority 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 authority or any moneys held in trust or otherwise for the payment of bonds or in any way to secure bonds. 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 authority and all banks and trust companies are authorized to give such security for such deposits.
