1. (1) Defined benefit members who terminate covered employment, accept a refund of their accumulated contributions, and later return to covered employment in the same system, are eligible for the GABA provisions in effect at the time the member returns to covered employment.
2. (2) Purchase of refunded service or allowable retroactive periods of service (for example, periods when excluded from membership, periods for which optional membership was declined, periods of service credit from other public retirement systems, or periods of federal employment) does not affect the member's hire date. The member remains subject to the GABA provisions applicable to their hire date, not the GABA in effect during the periods of refunded or retroactive service.
