7.23 B. Impact on Employer ERI Rate If Member Has Concurrent IMRF Employers

If a member participates with more than one IMRF employer, the employer cost for the ERI is determined as follows:

  1. If one employer adopts ERI and the other does not, the employer adopting ERI bears the entire cost of the ERI.

  2. If both employers adopt ERI, both employers will share the cost proportionately based on years of service credit and salary.
