Section 45-37A-51.193 Health Department Payments.

(a) The Jefferson County Department of Health shall pay into the fund from its general or otherwise appropriate funds its current service costs and its past service costs to be determined as of the date of the commencement of each fiscal year of the city as follows: (1) The actuaries shall determine the normal cost of the benefits provided by the system which are attributable to health department participants. (2) From the normal cost shall be subtracted the value of the health department participants’ contributions in the previous city fiscal year. (3) The remainder thus arrived at shall be divided by the total covered payroll of all health department participants as of the first day of the city fiscal year, the resultant percentage shall be called the current service percentage and the current service percentage shall be multiplied by the total covered payroll of all health department participants at the end of each payroll period to determine the health department’s current service cost for the payroll period. (4) The actuaries shall determine the single sum of unfunded accrued liability and shall amortize it from that date over a period of 30 years, attributing a ratable portion to the health department participants. (5) This unfunded accrued liability, as amortized over 30 years, shall be divided by total covered payroll of all health department participants, the resultant percentage shall be called the past service percentage and the past service percentage shall be multiplied by the total covered payroll of all such participants at the end of each payroll period to determine the past service cost for the payroll period. (b) During each fiscal year ending prior to October 31, 1981, the total contribution of the city shall have been not less than nine percent of total covered payroll determined under subsection (a). The amount by which such past service cost was reduced hereunder in any fiscal year of the city must have been paid by such city into the fund within the next two succeeding fiscal years of the city as an addition to past service cost as computed for the fiscal year in which such additional payment was made, except to the extent which the city had applicable credits under subdivision (2).
