Bonds of the authority may be sold at such price or prices and at such time or times as the board of directors of the authority may consider advantageous, at public or private sale. If bonds are to be sold by competitive bid on sealed bids or at public auction, the bonds may be sold only to the bidder whose bid reflects the lowest effective borrowing cost to the authority for the bonds being sold; provided, that if no bid acceptable to the authority is received, it may reject all bids. Notice of each such sale by competitive bids shall be given by publication in either a financial journal or a financial newspaper published in the City of New York, New York, and also by publication in a newspaper published in the State of Alabama, each of which notices must be published at least one time not less than 10 days before the date fixed for such sale. The board of directors may fix the terms and conditions under which such sale by competitive bids may be held; provided that such terms and conditions shall not conflict with any of the requirements of this article. The authority may pay out of the proceeds of the sale of its bonds all expenses, including publication and printing charges, fiscal agents' fees, attorneys' fees and other expenses which said board of directors may deem necessary and advantageous in connection with the authorization, advertisement, sale, execution and issuance of such bonds. Neither a public hearing nor consent of the state shall be a prerequisite to the issuance or sale of bonds by the authority.
