Retirement: public school employees; certain required annual contributions; modify. Amends secs. 41 & 43e of 1980 PA 300 (MCL 38.1341 & 38.1343e).

This bill modifies Michigan's public school employee retirement act to establish specific rules for calculating annual contribution rates. It requires that contribution rates for unfunded liabilities generally remain at least as high as the previous year's rate, with specific exceptions for university reporting units and a cap on the rate applied to payroll. Additionally, the legislation mandates that any extra contributions needed to cover unfunded liabilities must be paid through state appropriations rather than direct payroll deductions. These changes directly affect the Michigan Public School Employees Retirement System and the funding mechanisms used to support public school employees' pensions.
