(b) General obligation refunding bonds may be issued by the State from time to time pursuant to the authority contained in Amendment No. 666 to the Constitution of Alabama of 1901, as amended [Section 219.04], in aggregate principal amounts (which may exceed the principal amount of general obligation bonds being refunded) determined by the Bond Commission established pursuant to Section IX of Amendment No. 666 to the Constitution of Alabama of 1901, as amended [Section 219.04]; provided, however, that no such general obligation refunding bonds shall be issued unless (i) the present value of all debt service on such general obligation refunding bonds (computed with a discount rate equal to the true interest rate of such general obligation refunding bonds and taking into account all underwriting discount and other issuance expenses) shall not be greater than 97 percent of the present value of all debt service on the general obligation bonds to be refunded (computed using the same discount rate and taking into account the underwriting discount and other issuance expenses originally applicable to such general obligation bonds to be refunded) determined as if such general obligation bonds to be refunded were paid and retired in accordance with the schedule of maturities (considering mandatory redemption as a scheduled maturity) provided at the time of their issuance; and (ii) the average maturity of such general obligation refunding bonds, as measured from the date of issuance of such general obligation refunding bonds, shall not exceed by more than three years the average maturity of the general obligation bonds to be refunded, as also measured from such date of issuance, with the average maturity of any principal amount of general obligation bonds to be determined by multiplying the principal of each maturity by the number of years (including any fractional part of a year) intervening between such date of issuance and each such maturity, taking the sum of all such products, and then dividing such sum by the aggregate principal amount of general obligation bonds for which the average maturity is to be determined.
(c) The principal amount of general obligation bonds for which provision for payment has been made with proceeds of general obligation refunding bonds (including anticipated investment earnings thereon), shall not be deemed outstanding for purposes hereof.
(d) Except to the extent modified hereunder, the terms and provisions of Amendment No. 666 to the Constitution of Alabama of 1901, as amended [Section 219.04], and Amendment No. 796 to the Constitution of Alabama of 1901, as amended [Section 219.041], shall remain in full force and effect.
