(c) (1) As part of each actuarial valuation, the actuary shall determine the normal contributions, net of member contributions, on account of the State members of each State system.
(2) For each State system, the normal contribution rate equals the fraction that has:

(d) (1) Beginning July 1, 2023, each year the Board of Trustees shall set contribution rates for each State system that shall amortize:
(i) all unfunded liabilities or surpluses accrued as of June 30, 2023, over the time remaining until June 30, 2039; and

1. 15 years for experience gains and losses;
2. 25 years for the effect of changes in actuarial assumptions and methods;

(2) On recommendation of the system’s actuary, for the purpose of mitigating tail volatility in the annual contribution rate, the Board of Trustees may adjust the period of amortization under paragraph (1)(ii) of this subsection for liabilities or surpluses accrued in any fiscal year.
(e) The Board of Trustees may not certify contribution rates under this section that would result in a contribution rate below the normal cost, as determined by the system’s actuary.
