Section 5-10.2-2-11 - Contribution rate determination; contribution rate groups; supplemental contributions; contributions and contribution rates report(a) Based on the actuarial investigation and valuation in section 9 of this chapter, the board shall determine: (1) the normal contribution for each contribution rate group, which is the amount necessary to fund the pension portion of the retirement benefit;(2) the rate of normal contribution;(3) the unfunded accrued liability of the public employees' retirement fund, the pre-1996 account, and the 1996 account, which is the excess of total accrued liability over the fund's or account's total assets, respectively; and(4) the period, which must be thirty (30) years or a shorter period, necessary to amortize the unfunded accrued liability determined in subdivision (3).(b) Based on the information in subsection (a), the board may determine, in its sole discretion, contributions and contribution rates for individual employers or for a group of employers. However, after June 30, 2018, the board shall segregate from its determination of contributions and contribution rates any amounts attributable to estimated future postretirement benefit increases, thirteenth checks, or other benefit changes or adjustments granted by the general assembly after June 30, 2018.(c) The board shall require an employer to make a supplemental contribution to the fund in addition to the amounts described in subsection (a)(3) and (a)(4) in an amount necessary to pay the employer's share of the fund's actuarial unfunded liability that other employers would otherwise be required to pay because the employer's employees are becoming members of the plan under IC 5-10.3-12 or IC 5-10.4-8 instead of the fund. The amount necessary to pay an employer's contribution under this subsection in full must be made in a lump sum or in a series of payments determined by the board.(d) The board's determinations under subsection (a): (1) are subject to sections 1.5 and 11.5 of this chapter; and(2) may not include an amount for a retired member for whom the employer may not make contributions during the member's period of reemployment as provided under IC 5-10.2-4-8(e).(e) If the board determines contributions and contribution rates for one (1) or more employers under this section differ from the contributions and contribution rates determined by the actuarial investigation under section 9 of this chapter, the board shall notify the interim study committee for pension management oversight of this fact by reporting the board's action to the legislative services agency in an electronic format under IC 5-14-6.Amended by P.L. 127-2018,SEC. 8, eff. 7/1/2018.Amended by P.L. 217-2017,SEC. 56, eff. 7/1/2017.Amended by P.L. 241-2015, SEC. 4, eff. 7/1/2015.Amended by P.L. 195-2013, SEC. 2, eff. 7/1/2013.Amended by P.L. 35-2012, SEC. 36, eff. 7/1/2012.Amended by P.L. 23-2011, SEC. 10, eff. 7/1/2011.As added by Acts1977 , P.L. 53, SEC.2.
