(a) Any local government has the power and is authorized to issue by resolution revenue refunding bonds to refinance outstanding obligations heretofore or hereafter issued or lawfully assumed by the local government which are payable solely from all or any part of the revenues of one (1) or more enterprises, or from a combination of such revenues and taxes, to refinance any enterprise or combination of enterprises, and for such purpose or purposes to combine or divide any two (2) or more enterprises, and to provide for the rights of the holders thereof and to secure such bonds as provided in this part and part 1 of this chapter.

(b) No revenue refunding bonds shall be issued under this part and part 1 of this chapter, unless the governing body of the local government shall make a finding, which finding shall be conclusive, that one (1) or more of the following purposes will be accomplished:

(1) Cost savings to the public;

(2) Removal or modification of one (1) or more restrictive covenants; or

(3) Payment or discharge of all or any part of an issue or series of outstanding obligations, including any interest thereon, in arrears or to become due and for the payment of which sufficient funds are not available.

(c) Revenue refunding bonds may be issued to refinance more than one (1) issue of outstanding obligations, notwithstanding that such outstanding obligations may have been issued at different times and may be secured by the revenues of different enterprises; and any such enterprises may be operated as a single enterprise, subject to contract rights vested in the holders of obligations being refinanced.

(d) The resolution authorizing revenue refunding bonds may also provide for other bonds to be issued jointly with the revenue refunding bonds.
