The refunding assessment area bonds may be issued and delivered at any time prior to the date of maturity or redemption date of the assessment area bonds to be refunded that the authority deems to be in its best interest. The refunding assessment area bonds, except as specifically provided in this subsection (d) shall be issued in accordance with the provisions of this chapter with respect to assessment area bonds. Pending the time the proceeds derived from the sale of refunding assessment area bonds issued under this chapter are required for the purposes for which they were issued, the proceeds, upon authorization or approval of the governor, may be invested in obligations of, or obligations unconditionally guaranteed by the United States of America, or in savings accounts, time deposits, or certificates of deposit of any bank or trust company within or without the State, to the extent that such savings accounts, time deposits, or certificates of deposit are collaterally secured by a pledge of obligations of, or obligations unconditionally guaranteed by, the United States of America; or in obligation of any state of the United States of America or any agency, instrumentality, or local government thereof, the provision for payment of the principal and interest which have irrevocably been made by deposit of obligations of, or obligations unconditionally guaranteed by the United States of America.
To further secure assessment area bonds, or the assessment area bonds being refunded, or both, the State may enter into a contract with any bank or trust company, within or without the State, with respect to the safekeeping and application of the earnings of investments. All assessment area bonds refunded and redeemed by the issue and sale or issue and exchange of refunding assessment area bonds shall be defeased.
The determination of the authority with respect to the financial soundness and advantage of the issue and delivery of refunding assessment area bonds authorized, when approved by the governor and the director of finance, shall be conclusive, but nothing in this subsection (d) shall require the holders of any outstanding assessment area bonds being refunded to accept payment thereof otherwise than as provided in the assessment area bonds to be refunded.
