Sec. 855.407.  LIMITATION ON MUNICIPALITY CONTRIBUTION RATES.  (a)  The combined rates of a municipality's normal contributions and prior service contributions may not exceed:
(1)  9-1/2 percent of the total compensation paid by the municipality to the employees of its participating departments if the rate of member contributions of the employees of its participating departments is 7 percent of their compensation;
(2)  8-1/2 percent of the total compensation paid by the municipality to the employees of its participating departments if the rate of member contributions of the employees of its participating departments is 6 percent of their compensation;
(3)  7-1/2 percent of the total compensation paid by the municipality to the employees of its participating departments if the rate of member contributions of the employees of its participating departments is 5 percent of their compensation;  or
(4)  5-1/2 percent of the total compensation paid by the municipality to the employees of its participating departments if the rate of member contributions of the employees of its participating departments is 3 percent of their compensation.
(b)  The actuary annually shall determine the municipality normal contribution rate and the prior service contribution rate from the most recent data available at the time of the determination.  Before January 1 of each year, the board of trustees shall certify the rates to each participating municipality.  If a participating municipality has different rates of contribution for employees of different departments, the actuary shall determine the maximum rate for the municipality using the average rate of contribution prescribed for contributions of employees of its participating departments.  To compute the average rate the actuary shall consider the number of employees in each participating department of the municipality.
(c)  A reduction in the member contribution rate for employees of a participating municipality or in the municipality's matching rate does not reduce the maximum rate of contribution of the municipality.
(d)  If the dates of participation of each department of a municipality are not the same, the governing body of the municipality may request that, to determine the municipality normal contribution rate and prior service contribution rate and to determine the period during which the municipality must fund the obligations charged against its account in the benefit accumulation fund, all of its departments have a single composite participation date.  The actuary shall determine the composite participation date by computing an average weighted according to the number of members entering the retirement system on the actual dates of participation of the departments involved.
(e)  If the combined rates of a municipality's normal contributions and prior service contributions exceed the rate prescribed by Subsection (a), the rate for prior service contributions shall be reduced to the rate that equals the difference between the maximum rate prescribed by Subsection (a) and under Section 855.501, if applicable, and the normal contribution rate for the municipality.
(f)  The governing body of a municipality that is determined by the actuary to be unable to finance all obligations charged against its account in the benefit accumulation fund within the municipality's current amortization period may elect to have the municipality contribute to its account in the benefit accumulation fund at a rate that does not exceed in any year the sum of two percent and the maximum contribution rate specified by Subsection (a) and by Section 855.501, if applicable, and that the actuary annually may determine as necessary to finance the existing levels of benefits before the expiration of the municipality's current amortization period.
(g)  A municipality that begins participation in the retirement system on or after December 31, 1999, and any municipality already participating in the retirement system on that date whose governing body elects to have the municipality do so shall contribute to its account in the benefit accumulation fund at the combined rate of total compensation paid to its employees as the actuary determines is necessary to fund all obligations chargeable to its account in the fund within the municipality's amortization period, regardless of other provisions of this subtitle.
(h)  Subject to Subsection (i), if the board of trustees adopts any actuarial changes, including changes in actuarial assumptions or in actuarial method, that would result in any municipality having an increase in its combined contribution rate of more than one-half of one percent of the total compensation paid to its employees based on its current amortization period, the board may, after consultation with the actuary, take any or all of the following actions:
(1)  phase in the increase in the contribution rate for the municipality over a reasonable period of time;
(2)  increase the period for amortizing the municipality's unfunded actuarial accrued liabilities for a period that does not exceed 30 years; or
(3)  allow the municipality to request in writing an increase in the municipality's amortization period, provided that the new amortization period the municipality may be assigned equals the lesser of:
(A)  the number of years required to limit the increase in the combined rate to one-half of one percent of the total compensation paid to its employees; or
(B)  the maximum number of years, not to exceed 30 years, specified by the board of trustees.
(i)  A municipality may decline to phase in the increase in the municipality's contribution rate or increase the municipality's amortization period under Subsection (h).
