Section 39.35.255 - Contributions by employers(a) Each employer, except as provided in (h) of this section, shall contribute to the system every payroll period an amount calculated by applying a rate of 22 percent of the greater of the total of all base salaries(1) paid by the employer to employees who are active members of the system, including any adjustments to contributions required by AS 39.35.520; or(2) paid by the employer to employees who were active members of the system during the corresponding payroll period for the fiscal year ending(B) June 30, 2012, if that total is less than the total under (A) of this paragraph, and the employer is a municipality in which the population decreased by more than 25 percent between 2000 and 2010, according to the decennial census conducted by the United States Bureau of the Census.(b) The administrator shall allocate contributions received for full payment of(1) the actuarially determined employer normal cost for the plan; and(2) all contributions required by AS 39.30.370 and AS 39.35.750 for the fiscal year.(c) If, after allocation of contributions under (b) of this section, a portion of the employer contributions remains, the administrator shall apply that remaining portion toward payment of the past service liability of the plan.(d) Notwithstanding (a) of this section, the annual employer contribution rate may not be less than the rate sufficient to allow payment of the employer normal cost and the employer contributions required under AS 39.30.370 and AS 39.35.750.(e) An employer of a retired member rehired under AS 39.35.150 shall include that member's base salary when calculating the contribution amount established in (a) of this section.(f) All or a portion of the employer's share of any accrued actuarial liability to the plan may be prepaid in a lump sum. The commissioner may, by regulation, establish a minimum amount for the lump sum payment of a portion. The commissioner shall charge to the employer appropriate and reasonable costs to the plan attributable to a lump sum payment that are not greater than administrative costs applied to other employer contributions. If a lump sum payment is made, the payment shall be accounted for separately in accordance with regulations adopted by the commissioner. The regulations must provide for crediting to each lump sum payment account all earnings and losses received from investment of that payment. The lump sum payment shall be used solely to offset contributions under this section required of the employer that made the payment or on whose behalf the payment was made, taking into account earnings and losses from its investment. A lump sum payment made by or on behalf of an employer under this subsection, together with all earnings and losses from investment of that payment, may not be considered in calculating that employer's share of any discretionary payment authorized by the state that benefits multiple employers.(g) If all or a portion of the employer's share of any accrued actuarial liability to the plan is prepaid in a lump sum under (f) of this section, the administrator shall calculate a revised employer contribution rate for that employer in recognition of that prepayment not more than 30 days following the prepayment.(h) Notwithstanding any other provision of this section, the state as an employer shall contribute to the system every payroll period an amount sufficient to pay the actuarially determined employer normal cost, all contributions required under AS 39.30.370 and AS 39.35.750, and past service cost for members at the contribution rate adopted by the board under AS 37.10.220 for the fiscal year for that payroll period.(i) In this section, "normal cost" means the cost of providing the benefits expected to be credited, with respect to service, to all active members of the plan during the year beginning after the last valuation date.Amended by SLA 2021, ch. 9,§§sec.1, sec.2 eff. 7/1/2021.Amended by SLA 2018, ch. 49,sec. 2, eff. 6/29/2018.
