(a) The Arkansas Development Finance Authority may issue the Arkansas Unemployment Trust Fund Bonds for the purpose of refunding bonds previously issued under this subchapter if the total amount of bonds outstanding after the refunding is completed does not exceed the total amount authorized by this subchapter.
(b)
(1) To the extent that refunding bonds are issued and the principal amount of the refunding bonds is not in a greater principal amount than the outstanding principal amount of the bonds being refunded, the principal amount of the refunding bonds shall not be subject to the five-hundred-million-dollar limit.
(2) If the refunding bonds are issued in a greater principal amount than the bonds being refunded, the principal amount of the refunding bonds shall not count against the five-hundred-million-dollar limit so long as the aggregate debt service on the refunding bonds is less than the aggregate debt service on the bonds being refunded.
