17-5-1515. Reserve funds and appropriations. (1) The board may establish a capital reserve account and pay into it any:

(a) funds appropriated and made available by the state for the purpose of the account;

(b) proceeds of the sale of notes or bonds to the extent provided in the resolutions or indentures of the board authorizing their issuance; and

(c) other funds which may be available to the board from any other source for the purpose of the account.

(2) All funds held in the capital reserve account must be used solely for the payment of the principal of or interest on the bonds secured in whole or in part by the account or the debt service fund payments with respect to the bonds, the purchase or redemption of the bonds, the payment of interest on the bonds, or the payment of any redemption premium required to be paid when the bonds are redeemed prior to maturity. Funds in the account may not be withdrawn at any time in an amount that reduces the account to an amount less than the sum of minimum capital reserve requirements established in the resolutions or indentures of the board for the account except, with respect to bonds secured in whole or in part by the account, for the purpose of making payment, when due, of principal, interest, redemption premiums, and debt service fund payments for the payment of which other money pledged is not available. Any income or interest earned by or incremental to the capital reserve account due to its investment may be transferred to other accounts of the board to an extent that does not reduce the amount of the capital reserve account below the sum of minimum capital reserve requirements for the account.
