September 24, 2018 - Retired Returned to Work Employees of PLDs 

This is a follow up to the information we sent you on September 14, 2018 regarding upcoming pension plan changes for Participating Local Districts (PLD’s) in the consolidated plan.

The MainePERS Board of Trustees has now approved changes that apply to employees who retire and are rehired by a PLD.  Starting with October 2018 payroll reporting, employers must remit a contribution toward the unfunded actuarial liability (UAL) of the plan that is equal to 5% of earnable compensation for each retiree who becomes employed as a Retiree Return to Work (RRTW) on or after October 2nd, 2018.  These new RRTW employees must be reported on your monthly payroll with a Rate Schedule Number (RSN) of 96.  Any RRTW employee in a position on or before October 1, 2018 is grandfathered until June 30, 2021, and will continue to be reported with a RSN of 53.  Grandfathering means that no UAL payment is required on these employees until 2021.  Any future change to the RRTW UAL rate will be communicated at the same time other PLD contribution rates are updated.  

Please continue to submit a Membership Application through ESS for each new RRTW employee.  If you have any questions or concerns, please contact Employer Services at (207) 512-3200 or
