N.J. Stat. § 54:1-50

The State Treasurer shall, upon the warrant of the State Comptroller, annually pay to each participating municipality a share of amounts annually deposited in the "Municipal Purposes Tax Assistance Fund" and set aside for participating municipalities, in an amount derived pursuant to the following formula: MS = (F / D P) x P / I Where: MS is the share to be received by the participating municipality. (A per capita share of the amounts so deposited and set aside for participating municipalities, weighted by the municipal index of equalized valuation per capita of each participating municipality.) F is the total amount so deposited and set aside for participating municipalities. P is the population of each participating municipality. D P is the sum of the populations of all participating municipalities. I is the municipal index of equalized valuation per capita of the participating municipality. The amount to be distributed pursuant to this section to any participating municipality shall not be greater than an amount equal to 25% of the municipal purposes levy of the municipality for the tax year immediately preceding the tax year in which a payment is made under this act. If in any year the amount of funds so deposited and set aside for participating municipalities is other than the sum of the municipal shares for all participating municipalities, then each participating municipality shall receive from the amount so deposited and set aside an amount which is equal in proportion to its municipal share of the sum of the municipal shares of all participating municipalities.
