All money received by the board from whatever source derived, shall be transmitted by the board at least once in every calendar month to the State Treasurer, and shall be deposited in the State Treasury to the credit of the Public Buildings Construction Fund, which fund is hereby created and is appropriated for the purpose hereinafter provided. There shall be maintained within the fund three separate accounts for each series of certificates or revenue bonds covering all the public buildings authorized, under this part, at any one session of the Legislature:
(a) A construction account
(c) A sinking fund account
There shall be deposited to the credit of the respective series in the construction account the proceeds from the sale of each series of certificates or revenue bonds authorized under the provisions of this part. The money in each such account shall be expended, for the purposes authorized by this part, or as provided in the resolution, for the acquisition and construction of the public buildings, and in addition, for the payment of all costs and expenses of, and incident to, the issuance and sale of certificates or revenue bonds, and the payment of interest due or to become due on the certificates or revenue bonds during the period of actual construction, and for such further period as may be specified in the resolution for the issuance of the certificates or revenue bonds, not exceeding six
months after the period of construction.
There shall be deposited to the credit of the respective series in the revenue account all revenues, rentals, or receipts received from the operation of each series of public buildings acquired, constructed, or operated by the board under the provisions of this part, and all other money received by the board from whatever source derived, the disposition of which is not otherwise provided by this part.
The money in each revenue account shall be expended for the payment of the costs of operation and maintenance of the public buildings authorized by this part, including administrative expenses of the board, and for such other purposes as may be provided in the resolution, subject to any restrictions provided by law or by the resolution.
All money in each revenue account, except that part required to pay the costs of operating the board, as
provided for in the resolution authorizing the issuance of the certificates or revenue bonds, shall be set aside at regular intervals as provided in the resolution in separate sinking fund accounts for each series of certificates or revenue bonds, which are pledged to and charged with the payment of:
(a) The interest upon such certificates or revenue bonds as the interest falls due.
(b) The principal of the certificates or revenue bonds as it falls due.
(c) Any redemption value upon certificates or revenue bonds retired by call.
The use and disposition of the sinking fund account is subject to the regulations provided in the resolution. Each separate sinking fund account is an account for the benefit of each of the respective series of the certificates or revenue bonds
issued, without distinction or priority of one over another, except as to series. Subject to the provisions of the resolution, any money in the sinking fund account of each series in excess of the amount equal to one years interest on all certificates or revenue bonds of that series then outstanding may be applied to the purchase or redemption of certificates or revenue bonds of such series. All certificates or revenue bonds purchased or redeemed shall be canceled and shall not be issued again.
