Revising the ADEC rate and setting a minimum contribution rate for HPORS, SRS, and GWPORS

This bill updates the employer contribution rates for three Montana law enforcement retirement systems: the Highway Patrol Officers' Retirement System, the Sheriffs' Retirement System, and the Game Wardens' and Peace Officers' Retirement System. It establishes a minimum contribution rate of 38.33% for state employees and 13.115% for local employers, ensuring rates cannot fall below these amounts. The legislation also sets limits on annual rate changes, allowing increases or decreases of no more than 0.5% per year, and outlines how contributions should be calculated to cover legacy unfunded liabilities, contemporary unfunded liabilities, and normal costs of benefits as they accrue.
