(1) At any time prior to retirement, a member who is statutorily eligible to do so may:
(a) elect to purchase into their current retirement system all or any portion of their previously refunded service in that system; or
(b) elect to purchase service from another MPERA-administered retirement system for which the member has received or is eligible to receive a refund.
(2) Section (1)(b) shall not be construed to allow the purchase of service between two retirement systems while the individual is a member of both systems.
(3) In order to purchase the service, an eligible member must file a request to purchase service with MPERA identifying, in writing, the system to which the member currently contributes and the period of employment which is to be purchased.
(4) After reviewing the information in its files, MPERA shall notify the member of the amount of service eligible to be purchased and the cost of that service.
