Michigan Compiled Laws, Chapter 38. Civil Service and Retirement § 38.1341a

Sec. 41a.(1) For fiscal years that begin after March 27, 1996, the retirement system shall determine a separate contribution rate for a university reporting unit. Subject to this subsection, the retirement system shall determine the separate contribution rate in the manner prescribed in section 41,  1 except that the unfunded actuarial accrued liability must be amortized over 40 years beginning October 1, 1996 and ending on September 30, 2036, with the payment schedule for universities being based on and applied to the combined payrolls of the universities' employees who are members and who were hired before January 1, 1996 and the universities' employees who would have been members after December 31, 1995, but for the enactment of 1995 PA 272.  2Beginning with the state fiscal year ending September 30, 2016 and for each subsequent fiscal year, the combined payrolls used for the payment schedule for the university reporting units must include each university reporting unit's combined payroll, as projected by the actuary based on the actuarial valuation for each following fiscal year, except that the combined payroll for each university reporting unit must not be less than the combined payroll projected for each subsequent fiscal year for each university reporting unit by the actuary based on the September 30, 2012 actuarial valuation. The amount of the unfunded accrued liability on which the separate contribution rate is determined must be that amount which a university reporting unit is legally responsible for and is calculated by actuarial analysis. Any reduction in the unfunded liability of the system under governmental action affecting the entire system will be allocated to all reporting units including universities as determined by the system's actuary. For the state fiscal year ending September 30, 2007, the contribution for unfunded actuarial accrued liability must be equal to 4.5% of the unfunded actuarial accrued liability.

(2) As used in this section, “university reporting unit” means a reporting unit that is a university listed in the definition of public school employee under section 6.  3
