2. a. As used in section 1 of this act,”equity interest” means the excess in value between the assets to be acquired by the withdrawing district pursuant to section 3 of P.L.1975, c.360 (C. 18A:13-53) and the proportionate contribution made by the withdrawing district to all regional assets, adjusted for replacement value.

b. The calculation required to establish the equity interest as defined in subsection a. of this section shall be the excess, if any, of the replacement cost of the buildings, grounds, furnishings, equipment, and additions thereto to which the withdrawing district shall take title upon withdrawal pursuant to section 3 of P.L.1975, c.360 (C. 18A:13-53) over that amount obtained by multiplying the replacement cost of all the regional district’s buildings, grounds, furnishings, equipment, and additions thereto by a ratio that reflects the proportionate contributions made by the withdrawing district to the payment of the cost of the regional district’s assets. The proportionate contribution shall be determined by reference to the proportion of the revenues of the regional district contributed by the withdrawing district in each fiscal year of the life of all of the buildings, grounds, furnishings, equipment, and additions thereto of the regional district.
