1. The year 2000 plan intends to follow a financing pattern which computes and requires contribution amounts which, expressed as percents of active member payroll, will remain approximately level from year to year and from one generation of citizens to the next generation. Such contribution determinations require regular actuarial valuations, which shall be made by the board’s actuary, using assumptions and methods adopted by the board after consulting with its actuary. The entry age-normal cost valuation method shall be used in determining normal cost, and contributions for unfunded accrued liabilities shall be determined using level percent-of-payroll amortization. For purposes of this subsection and section 104.436, the actuary shall determine a single contribution rate applicable to both closed plan and year 2000 plan participants and, in determining such rate, make estimates of the probabilities of closed plan participants transferring to the year 2000 plan.

2. At least ninety days before each regular session of the general assembly, the board of the Missouri state employees’ retirement system shall certify to the division of budget the contribution rate necessary to cover the liabilities of the year 2000 plan administered by such system, including costs of administration, expected to accrue during the next appropriation period. The commissioner of administration shall request appropriations based upon the contribution rate so certified. From appropriations so made, the commissioner of administration shall certify contribution amounts to the state treasurer who in turn shall immediately pay the contributions to the year 2000 plan.

3. The employers of members covered by the Missouri state employees’ retirement system who are not paid out of funds that have been deposited in the state treasury shall remit following each pay period to the year 2000 plan an amount equal to the amount which the state would have paid if those members had been paid entirely from state funds. Such employers shall maintain payroll records for a minimum of five years and shall produce all such records as requested by the system. The system is authorized to request from the state office of administration an appropriation out of the annual budget of any such employer in the event such records indicate that such employer has not contributed the amounts required by this section. The office of administration shall request such appropriation which shall be equal to the amount necessary to replace any shortfall in contributions as determined by the system. From appropriations so made, the commissioner of administration shall certify contribution amounts to the state treasurer who in turn shall immediately pay such contributions to the year 2000 plan.

4. At least ninety days before each regular session of the general assembly, the board of the transportation department and highway patrol retirement system shall certify to the department of transportation and the department of public safety the contribution rate necessary to cover the liabilities of the year 2000 plan administered by such system, including costs of administration, expected to accrue during the next biennial or other appropriation period. Each department shall include in its budget and in its request for appropriations for personal service the sum so certified to it by such board, and shall present the same to the general assembly for allowance. The sums so certified and appropriated, when available, shall be immediately paid to the system and deposited in the highway and transportation employees’ and highway patrol retirement and benefit fund.

5. These amounts are funds of the year 2000 plan and shall not be commingled with any funds in the state treasury.
