Colo. Rev. Stat. § 35-75-119
The authority may invest any money held in reserve, sinking funds, capital reserve funds, or any funds not required for immediate disbursement in property or in securities in which the state treasurer may legally invest money subject to the state treasurer's control; sell from time to time such securities thus purchased and held; and deposit securities in a trust bank within or without the state. In addition, the authority may invest the money in unsecured promissory notes of a national bank having the highest investment ratings. Any money deposited in a banking institution shall be secured in such manner and subject to such terms and conditions as the board may determine, with or without payment of interest on such deposit, including, without limitation, time deposits evidenced by certificates of deposit. A commercial bank incorporated under the laws of this state that may act as a depository of the money of the authority may issue indemnifying bonds or may pledge such securities as may be required by the board.
