Indiana Code Title 8. Utilities and Transportation § 8-10-1-14

Sec. 14. The proceeds of the bonds of each issue shall be used solely for the payment of the cost of the port or project for which such bonds shall have been issued, and shall be disbursed in such manner and under such restrictions, if any, as the ports of Indiana may provide in the resolution authorizing the issuance of such bonds or in the trust agreement mentioned in this chapter securing the same.  If the proceeds of the bonds of any issue, by error of estimates or otherwise, shall be less than such cost, additional bonds may in like manner be issued to provide the amount of such deficit, and, unless otherwise provided in the resolution authorizing the issuance of such bonds or in the trust agreement securing the same, shall be deemed to be of the same issue and shall be entitled to payment from that same fund without preference or priority of the bonds first issued.  If the proceeds of the bonds of any issue shall exceed the cost of the port or project for which the same shall have been issued, the surplus shall be deposited to the credit of the sinking fund for such bonds.  Prior to the preparation of definitive bonds, the ports of Indiana may, under like restrictions, issue interim receipts or temporary bonds, with or without coupons, exchangeable for definitive bonds when such bonds shall have been executed and are available for delivery.  The ports of Indiana may also provide for the replacement of any bonds which shall become mutilated or shall be destroyed or lost.  Bonds and any other instruments or the security for the bonds and other instruments that are authorized by this article may be issued under the provisions of this article without obtaining the consent of any officer, department, division, commission, board, bureau, or agency of the state, and without any other proceedings or the happening of any other conditions or things than those proceedings, conditions, or things which are specifically required by this chapter.
