Ala. Code § 11-64-4
Securities issued under the authority of this chapter shall mature at such time or times as the governing body of the issuer shall determine, not later than the date on which the last installment of the grant is reasonably expected to be received. The total principal amount of securities which may be issued in respect of a grant shall not exceed the reasonably estimated proceeds of the grant. The determination of the governing body of the issuer of the date on which the last installment of the grant will be received and the amounts of the proceeds of any grant to be received shall be conclusive. Securities issued under the authority of this chapter shall be of such denomination and tenor, shall contain such covenants and restrictions and provisions and shall be payable at such place or places, within or without the state, as the governing body of the issuer shall determine. Such securities shall be executed in the name of the issuer by such officer as such governing body shall designate and attested by such other officer thereof as such governing body shall designate, with the seal of the issuer impressed thereon, but coupons for interest, if interest is evidenced by coupons, need be signed only by the officer who executes the securities. Execution by facsimile signature and seal in the manner authorized by law for bonds of a municipality may be authorized by the governing body.
