17-5-1624. Trust indenture. (1) In the discretion of the board, the bonds or notes of the board may be secured by a trust indenture between the board and a corporate trustee, which may be a trust company or bank having the power of a trust company inside or outside the state. A trust indenture may contain provisions for protecting and enforcing bondholders' rights and remedies that are reasonable and proper and not in violation of law, including covenants setting forth the duties of the board in relation to the exercise of its powers and the custody, safeguarding, and application of all money. The board may provide by a trust indenture for the payment of the proceeds of the bonds or notes and the revenues to the trustee under the trust indenture of another depository and for the method of disbursement, with safeguards and restrictions it considers necessary.
(2) All expenditures incurred in carrying out a trust indenture may be treated as part of the general overhead cost of the board.
