Retirement: state employees; membership in the retirement system of certain law enforcement officers; provide for. Amends secs. 3, 4, 14 & 70 of 1986 PA 182 (MCL 38.1603 et seq.) & adds secs. 14b & 24c.

This bill amends the Michigan State Police Retirement Act to update definitions and calculations related to retirement benefits for state employees and law enforcement officers. It clarifies terms such as "final average compensation," which determines the salary base used to calculate pensions, by specifying how overtime, shift differentials, and leave hours are counted over the last two or five years of service depending on when the officer joined. The legislation also refines rules regarding eligible retirement plans and distributions, ensuring that certain types of payments, like those tied to life expectancy or long-term annuities, are correctly excluded from specific categories. By revising sections of the existing law, the bill aims to provide clearer guidelines for how retirement allowances are computed and managed for current and future members of the system.
