(a) General. The authority is authorized from time to time to sell and issue its bonds for the purpose of providing funds to be transferred to and deposited in the Alabama Trust Fund and the Rainy Day Account, to provide additional funds to the Alabama Medicaid Agency, for paying the costs of transportation projects, and for the purpose of refunding any or all of the authority’s outstanding bonds.

(b) Sources of payment. Bonds issued by the authority shall be solely and exclusively an obligation of the authority and shall not create an obligation or debt of the state. Such bonds shall not be general obligations of the authority but shall be payable solely from one or more of the following sources:

(1) Appropriated funds.

(2) The income or proceeds realized by the authority under any mortgage or security granted to the authority.

(3) Amounts derived from any letter of credit, insurance policy, or other form of credit enhancement applicable to the bonds.

(4) Any reserve or other fund established for such purpose by the authority.

(5) Any earnings on the proceeds of bonds invested by the authority pending their disbursement.

(6) Any other revenues that may hereafter be available to the authority.

Unless otherwise provided in the resolution of the directors of the authority authorizing the issuance of the bonds, all pledges of appropriated funds made by the authority shall be on a parity so that all bonds of the authority secured by a pledge of appropriated funds shall be equally and ratably so secured without regard to time of issuance. Bonds issued by the authority shall be construed to be negotiable instruments, although payable solely from a specified source, as provided herein.

(c) Security for the bonds. The principal of and interest on any bonds issued by the authority shall be secured by a pledge of the appropriated funds or other monies and property available to the authority and may be secured by a trust indenture evidencing such pledge or by a foreclosable mortgage and deed of trust conveying as security for such bonds all, or any part, of the authority's property. The resolution under which the bonds are authorized to be issued or any such trust indenture or mortgage may contain any agreements and provisions respecting the rights, duties, and remedies of the parties to any such instrument and the parties for the benefit for whom such instrument is made and the rights and remedies available in the event of default as the authority shall deem advisable and which are not in conflict with the provisions of this article.

(d) General provisions respecting form, sale, and execution of the bonds. All bonds issued by the authority shall be signed by its president or vice president and attested by its secretary and the seal of the authority shall be affixed thereon. A facsimile of the signature of one or both of the officers may be printed or otherwise reproduced on any such bonds in lieu of being manually subscribed thereon and a facsimile of the seal of the authority may be printed or otherwise reproduced on any of the bonds in lieu of being manually affixed thereto. Any bonds of the authority may be executed and delivered by it at any time and from time to time, and shall be in the form and denominations and of such tenor and maturities, shall bear such rate or rates of interest, shall be payable at such times and evidenced in such manner, may be made subject to redemption at the option of the authority at such times and after such notice and on such conditions and at such redemption price or prices, and may contain such other provisions not inconsistent herewith, all as may be provided by the resolution of the directors of the authority under which the bonds are authorized to be issued. Bonds of the authority may be sold, in the discretion of the authority, either (1) at public sale or sales, based on sealed bids received either electronically or on paper, after advertisement as may be prescribed by the authority, to the bidder whose bid reflects the lowest true interest cost to the authority computed to the respective maturities of the bonds sold; provided, however, that if no bid deemed acceptable by the authority is received, all bids may be rejected and the bonds offered again for public sale in accordance with the terms herein prescribed; or (2) by negotiated sale. Such bonds may be issued in the form of current interest bonds, capital appreciation bonds, or convertible capital appreciation bonds and may be issued as serial bonds or term bonds, all as may be directed by the authority.

(e) Other matters. Any bonds of the authority may be used by the holder as security for any funds belonging to the state, or to any political subdivision, instrumentality, or agency of the state, in any instance where security for the deposits may be required by law. Unless otherwise directed by the court having jurisdiction, or the document that is the source of authority, a trustee, executor, administrator, guardian, or one acting in any other fiduciary capacity may, in addition to any other investment powers conferred by law and with the exercise of reasonable business prudence, invest trust funds and bonds of the authority. Bonds of the authority shall be legal investments for funds of the Teachers' Retirement System of Alabama, the Employees' Retirement System of Alabama, and the State Insurance Fund.
