N.J. Stat. § 43:15A-24
The contingent reserve fund shall be the fund in which shall be credited contributions made by the State and other employers.
With respect to the State, 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, excluding the special asset value set forth in section 38 of P.L. 2010, c. 1(C.43:3C-14), 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 March 31, 1996 shall be the full market value of the assets as of that date and, with respect to the valuation assets allocated to the State, 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. Notwithstanding the first sentence of this paragraph, the valuation assets for the valuation period ending June 30, 1999 shall be the full market value of the assets as of that date.
"Excess valuation assets" for a valuation period means, with respect to the valuation assets allocated to the State:
"Excess valuation assets" for a valuation period means, with respect to the valuation assets allocated to other employers:
If there are excess valuation assets allocated to the State or to the other employers for the valuation period ending March 31, 1996, the normal contributions payable by the State or by the other employers for the valuation periods ending March 31, 1996 and March 31, 1997 which have not yet been paid to the retirement system shall be reduced to the extent possible by the excess valuation assets allocated to the State or to the other employers, respectively, provided that with respect to the excess valuation assets allocated to the State, 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 allocated to the State or to the other employers for a valuation period ending after March 31, 1996, the State Treasurer may reduce the normal contribution payable by the State or by the other employers for the next valuation period as follows:
For calendar years 1998 and 1999, the rate of contribution of members of the retirement system under section 25 of P.L. 1954, c.84 (C.43:15A-25) shall be reduced by 1/2 of 1% from excess valuation assets and for calendar years 2000 and 2001, the rate of contribution shall be reduced by 2% from excess valuation assets. Thereafter, through calendar year 2007, the rate of contribution of members of the retirement system under that section for a calendar year shall be reduced equally with normal contributions to the extent possible, but not by more than 2%, from excess valuation assets if the State Treasurer determines that excess valuation assets shall be used to reduce normal contributions by the State and local employers for the fiscal year beginning immediately prior to the calendar year, or for the calendar year for local employers whose fiscal year is the calendar year, and excess valuation assets above the amount necessary to fund the reduction for that calendar year in the member contribution rate plus an equal reduction in the normal contribution shall be available for the further reduction of normal contributions, subject to the limitations prescribed by this subsection.
If there are excess valuation assets after reductions in normal contributions and member contributions as authorized in the preceding paragraphs for a valuation period beginning with the valuation period ending June 30, 1999, an amount of excess valuation assets not to exceed the amount of the member contributions for the fiscal year in which the normal contributions are payable shall be credited to the benefit enhancement fund. The amount of excess valuation assets credited to the benefit enhancement fund shall not exceed the present value of the expected additional normal contributions attributable to the provisions of P.L. 2001, c. 133 payable on behalf of the active members over the expected working lives of the active members in accordance with the tables of actuarial assumptions for the valuation period. No additional excess valuation assets shall be credited to the benefit enhancement fund after the maximum amount is attained. Interest shall be credited to the benefit enhancement fund as provided under section 33 of P.L. 1954, c.84 (C.43:15A-33).
The normal contribution for the increased benefits for active employees under P.L. 2001, c. 133 shall be paid from the benefit enhancement fund. If assets in the benefit enhancement fund are insufficient to pay the normal contribution for the increased benefits for a valuation period, the State shall pay the amount of normal contribution for the increased benefits not covered by assets from the benefit enhancement fund.
The State Treasurer shall reduce the normal and accrued liability contributions payable by employers other than the State, excluding the contribution payable from the benefit enhancement fund, to a percentage of the amount certified annually by the retirement system, which percentage shall be: for payments due in the State fiscal year ending June 30, 2005, 20%; for payments due in the State fiscal year ending June 30, 2006, not more than 40%; for payments due in the State fiscal year ending June 30, 2007, not more than 60%; and for payments due in the State fiscal year ending June 30, 2008, not more than 80%.
The State Treasurer shall reduce the normal and accrued liability contributions payable by employers other than the State, excluding the contribution payable from the benefit enhancement fund, to 50 percent of the amount certified annually by the retirement system, for payments due in the State fiscal year ending June 30, 2009. An employer that elects to pay the reduced normal and accrued liability contribution shall adopt a resolution, separate and apart from other budget resolutions, stating that the employer needs to pay the reduced contribution and providing an explanation of that need which shall include (1) a description of its inability to meet the levy cap without jeopardizing public safety, health, and welfare or without jeopardizing the fiscal stability of the employer, or (2) a description of another condition that offsets the long term fiscal impact of the payment of the reduced contribution. An employer also shall document those actions it has taken to reduce its operating costs, or provide a description of relevant anticipated circumstances that could have an impact on revenues or expenditures. This resolution shall be submitted to and approved by the Local Finance Board after making a finding that these fiscal conditions are valid and affirming the findings contained in the employer resolution.
An employer that elects to pay 100 percent of the amount certified by the retirement system for the State fiscal year ending June 30, 2009 shall be credited with such payment and any such amounts shall not be included in the employer's unfunded liability.
The actuaries for the retirement system shall determine the unfunded liability of the retirement system, by employer, for the reduced normal and accrued liability contributions provided under P.L. 2009, c. 19. This unfunded liability shall be paid by the employer in level annual payments over a period of 15 years beginning with the payments due in the State fiscal year ending June 30, 2012 and shall be adjusted by the rate of return on the actuarial value of assets.
The retirement system shall annually certify to each employer the contributions due to the contingent reserve fund for the liability under P.L. 2009, c. 19. The contributions certified by the retirement system shall be paid by the employer to the retirement system on or before the date prescribed by law for payment of employer contributions for basic retirement benefits. If payment of the full amount of the contribution certified is not made within 30 days after the last date for payment of employer contributions for basic retirement benefits, interest at the rate of 10% per year shall be assessed against the unpaid balance on the first day after the thirtieth day.
The State shall pay into the contingent reserve fund during the ensuing year the amount so determined. The death benefits, payable as a result of contribution by the State under the provisions of this chapter upon the death of an active or retired member, shall be paid from the contingent reserve fund.
