INCREASE IN OWNERSHIP SHARES.

(a) An agreement under this chapter may provide for a political subdivision to increase its present or future ownership share of the electric utility facilities by installment purchase payments and for another political subdivision that is a party to the agreement to transfer, in consideration of those payments, any portion of its present or future ownership share of the facilities to the purchasing political subdivision. (b) A payment made by a political subdivision to acquire an ownership interest is not treated as a maintenance and operating expense but is treated as a capital cost as if the political subdivision had issued bonds to construct or acquire the ownership interest, unless otherwise specified in the agreement.
