b. Upon the basis of the tables recommended by the actuary which the commission adopts and regular interest, the actuary shall annually determine if there is an amount of the accrued liability of the retirement system, computed under the projected unit credit method, which is not already covered by the assets of the retirement system, valued in accordance with the asset valuation method established in this section. This shall be known as the "unfunded accrued liability." If there was no unfunded accrued liability for the valuation period immediately preceding the current valuation period, the actuary, using the total amount of this unfunded accrued liability, shall compute the initial amount of contribution which, if paid annually in level dollars for a specific period of time, will amortize this liability. The State Treasurer shall determine, upon the advice of the Director of the Division of Pensions and Benefits, the commission and the actuary, the time period for full funding of this liability, which shall not exceed 30 years. This shall be known as the "accrued liability contribution." Thereafter, any increase or decrease in the unfunded accrued liability as a result of actuarial losses or gains for subsequent valuation years shall serve to increase or decrease, respectively, the amortization period for the unfunded accrued liability, unless an increase in the amortization period will cause it to exceed 30 years. If an increase in the amortization period as a result of actuarial losses for a valuation year would exceed 30 years, the accrued liability contribution shall be computed for the valuation year in the same manner provided for the computation of the initial accrued liability contribution under this section. Beginning with the July 1, 2019 actuarial valuation, the accrued liability contribution shall be computed so that if the contribution is paid annually in level dollars, it will amortize this unfunded accrued liability over a closed 30-year period. Beginning with the July 1, 2029 actuarial valuation, when the remaining amortization period reaches 20 years, any increase or decrease in the unfunded accrued liability as a result of actuarial losses or gains for subsequent valuation years shall serve to increase or decrease, respectively, the amortization period for the unfunded accrued liability, unless an increase in the amortization period will cause it to exceed 20 years. If an increase in the amortization period as a result of actuarial losses for a valuation year would exceed 20 years, the accrued liability contribution shall be computed for the valuation year in the same manner provided for the computation of the initial accrued liability contribution under this section. The State may pay all or any portion of its unfunded accrued liability under the retirement system from any source of funds legally available for the purpose, including, without limitation, the proceeds of bonds authorized by law for this purpose.
The value of the assets to be used in the computation of the contributions provided for under this section for valuation periods shall be the value of the assets for the preceding valuation period increased by the regular interest rate, plus the net cash flow for the valuation period (the difference between the benefits and expenses paid by the system and the contributions to the system) increased by one half of the regular interest rate, plus 20% of the difference between this expected value and the full market value of the assets as of the end of the valuation period. This shall be known as the "valuation assets." Notwithstanding the first sentence of this paragraph, the valuation assets for the valuation period ending June 30, 1996 shall be the full market value of the assets as of that date and shall include the proceeds from the bonds issued pursuant to the "Pension Bond Financing Act of 1997," P.L. 1997, c. 114(C.34:1B-7.45 et seq.), paid to the system by the New Jersey Economic Development Authority to fund the unfunded accrued liability of the system.
"Excess valuation assets" means the valuation assets for a valuation period less the actuarial accrued liability for the valuation period, if the sum is greater than zero. If there are excess valuation assets for the valuation period ending June 30, 1996, the normal contributions for the valuation periods ending June 30, 1996 and June 30, 1997 which have not yet been paid to the retirement system shall be reduced to the extent possible by the excess valuation assets, provided that the General Fund balances that would have been paid to the retirement system except for this provision shall first be allocated as State aid to public schools to the extent that additional sums are required to comply with the May 14, 1997 decision of the New Jersey Supreme Court in Abbott v. Burke. If there are excess valuation assets for a valuation period ending after June 30, 1996, the State Treasurer may reduce the normal contribution payable for the next valuation period as follows:
(1) for valuation periods ending June 30, 1997 through June 30, 2001, to the extent possible by up to 100% of the excess valuation assets;(2) for the valuation period ending June 30, 2002, to the extent possible by up to 84% of the excess valuation assets;(3) for the valuation period ending June 30, 2003, to the extent possible by up to 68% of the excess valuation assets; and(4) for valuation periods ending June 30, 2004 through June 30, 2007, to the extent possible by up to 50% of the excess valuation assets.
