(1) Refunding bonds, obligations, or other evidences of indebtedness described in subsection (2) are issued subject to the revised municipal finance act, 2001 PA 34, MCL 141.2101 to 141.2821.

  (2) Pursuant to the revised municipal finance act, 2001 PA 34, MCL 141.2101 to 141.2821, a local governmental unit may issue refunding bonds, obligations, or other evidences of indebtedness to refund all or a portion of the bonds, obligations, or other evidences of indebtedness issued for purposes specified in this act. Except as otherwise provided in section 12(1), if refunding bonds, obligations, or other evidences of indebtedness are issued, an assignment or pledge of distributions of taxes from the convention facility development fund for the payment of principal or interest on the refunded bonds, obligations, or other evidences shall apply, after the issuance of the refunding bonds, only to the refunding bonds, obligations, or other evidences of indebtedness and to any bonds, obligations, or other evidences of indebtedness that were not refunded and to which the assignment or pledge previously applied.

  (3) A local governmental unit that refunds bonds, obligations, or other evidences of indebtedness pursuant to subsection (2) may dedicate distributions of taxes from the convention facility development fund to the payment of principal, interest, or credit support fees or other costs of issuance or of the maintenance of any required reserves for general obligation bonds, obligations, or other evidences of indebtedness issued or to be issued for purposes specified in this act but not pursuant to the authority granted in this act or may reimburse itself for such payments from such distributions. However, distributions to a local governmental unit pursuant to this subsection in any state fiscal year shall not exceed the lesser of the following:

  (a) Principal, interest, or credit support fees or other costs of issuance or of the maintenance of required reserves payable in the state fiscal year on the bonds, obligations, or other evidences of indebtedness to which the distributions are dedicated.

  (b) The difference between the amount that would have been distributed to the local governmental unit had it not issued refunding bonds pursuant to subsection (2) and the amount of distribution of taxes to which an assignment or pledge applies under subsection (2).

  (4) After September 30, 1999, taxes shall not be distributed from the convention facility development fund pursuant to subsection (3).

  (5) If bonds, obligations, or other evidences of indebtedness are to be issued for the purposes set forth in section 8(2), for which all or a portion of the distribution of taxes that the local governmental unit is eligible to receive are pledged or assigned as set forth in subsection (1) or (2), and if as a direct result of the acquiring, constructing, improving, enlarging, renewing, replacing, or in conjunction with these activities, repairing, furnishing, equipping, or leasing of a convention facility financed from the proceeds of the bonds, obligations, or other evidences of indebtedness, it is necessary for the state to expend money from the state trunk line fund from the proceeds of bonds issued by this state payable from deposits into the state trunk line fund, or from direct appropriations for the costs of relocating, constructing, or reconstructing highways, roads, streets, or bridges, and costs ancillary thereto, then before the issuance of the bonds, obligations, or other evidences of indebtedness, the state treasurer shall determine that the total amount of these costs to be paid from the state trunk line fund, from the proceeds of bonds or notes payable from deposits into the state trunk line fund, or from direct appropriations of this state, excluding any of the cost to be reimbursed to this state by the federal government, any local unit of government or authority or agency thereof, or any other person or entity, shall not exceed 25% of the total cost of the relocation, construction, or reconstruction of highways, roads, streets, and bridges, and costs ancillary to those costs, directly resulting from the convention facility project purposes described in section 8(2). For purposes of the validity of the bonds, obligations, or other evidences of indebtedness, the determination of the state treasurer is conclusive as to the matters stated in the determination. If after the determination by the state treasurer the total costs of relocating, constructing, and reconstructing highways, roads, streets, and bridges, and costs ancillary thereto, increase, this state shall not expend from the state trunk line fund, from the proceeds from bonds payable from deposits in the state trunk line fund, or from direct appropriations of this state, any additional funds that cause the total expenditure by this state from these sources, after any reimbursement, to exceed 25% of the total cost, as increased, of the relocation, construction, and reconstruction, including ancillary costs. An expenditure by this state in violation of this subsection does not invalidate or otherwise adversely affect any previously issued bonds, obligations, or other evidences of indebtedness described in this section or any security therefor.
