38-737. Employer contributions

A. Employer contributions shall be a percentage of compensation of all employees of the employers, excluding the compensation of those employees who are members of the defined contribution program administered by ASRS, as determined by the ASRS actuary pursuant to this section for June 30 of the fiscal year immediately preceding the preceding fiscal year, except that beginning with fiscal year 2001-2002 the contribution rate shall not be less than two percent of compensation of all employees of the employers. Beginning July 1, 2011 through June 29, 2016, the total employer contribution shall be determined on the projected unit credit method. Beginning June 30, 2016, the board shall determine the actuarial cost method pursuant to section 38-714. The total employer contributions shall be equal to the employer normal cost plus the amount required to amortize the past service funding requirement over a period that is determined by the board and consistent with generally accepted actuarial standards. In determining the past service funding period, the board shall seek to improve the funded status whenever the ASRS trust fund is less than one hundred percent funded.

B. All contributions made by the employer and allocated to the fund established by section 38-712 are irrevocable and shall be used as benefits under this article or to pay expenses of ASRS.

C. The required employer contributions shall be determined on an annual basis by an actuary who is selected by the board and who is a fellow of the society of actuaries. ASRS shall provide by December 1 of each fiscal year to the governor, the speaker of the house of representatives and the president of the senate the contribution rate for the ensuing fiscal year and the unfunded actuarial accrued liability, the funded status based on the actuarial value of assets and market value of assets and the annualized rate of return and the ten-year rate of return as of June 30 of the prior fiscal year.
