The Bonds may be sold by the Authority from time to time in series, and if sold in more than one series, may all be authorized in one initial resolution of the Authority with the pledges therefor made by the Authority in such initial resolution although some of the details applicable to each series may be specified in the respective resolutions under which the different series are issued. The Authority, in the course of establishing, by resolution, a principal amount of Bonds to be authorized for sale at any given time, or to be sold in any series, may take into account the existence of any unexpended proceeds of prior issues of bonds of the Authority (and of any other issuer, if such should be deemed by the Authority to be relevant), and may structure the portions of the allocations provided for in Section 16-16B-9 to be distributed from the proceeds of a particular series (constituting less than all the Bonds authorized by this chapter) as the Authority deems necessary or prudent in order to enable the Authority to comply with any tax covenants that may be required of it, or that may be deemed by it to be prudent to be given by it, in connection with the sale of any series of the Bonds. Each series of the Bonds shall be sold competitively only at public sale, on sealed bids which may be submitted either electronically or in writing, after such advertisement as shall be prescribed by the Authority and at such time or times as the Authority may consider advantageous, to the bidder whose bid reflects the lowest true interest cost to the Authority computed to the respective maturities of the Bonds being sold (considering mandatory redemption as scheduled maturity); provided, that if no bid deemed acceptable by the Authority is received it may reject all bids. The Authority may fix the method and the terms and conditions under which the sale of any series of the Bonds may otherwise be held; provided that such terms and conditions shall not conflict with any requirement of this chapter. Approval by the Governor of Alabama of the terms and conditions under which any of the Bonds may be issued shall be requisite to their validity. Before any series of the Bonds shall be offered for sale by the Authority, the Governor shall first determine that the issuance of that series of Bonds and the application of the taxes pledged to the payment of the principal of the Bonds as they mature and the interest thereon as the same shall come due will not impair the adequacy of the Trust Fund to pay appropriations therefrom and to support the public schools and institutions of higher learning during the period over which the Bonds will mature. The Governor's determination in this regard shall be in writing signed by the Governor and such determination shall be final and conclusive. Neither a public hearing nor consent of the State Department of Finance or any other department or agency shall be a prerequisite to the issuance of any of the Bonds.
