This section applies to a member of the Employees’ Pension System or Teachers’ Pension System who has prior service in a part of the Employees’ Pension System or Teachers’ Pension System that is subject to a different rate of benefit accrual. A member who is subject to the contributory pension benefit, Alternate Contributory Pension Selection, or Reformed Contributory Pension Benefit is entitled to combine the member’s prior eligibility service with the member’s current service if the member: at the time of separation from employment, was entitled to a vested allowance from: the Employees’ Pension System; or the Teachers’ Pension System; did not transfer to the Employees’ Pension System or the Teachers’ Pension System from the Employees’ Retirement System or Teachers’ Retirement System after April 1, 1998; and has completed 1 year of employment as a member of the pension benefit or selection in which the member is earning service credit as an active member at the time the prior service credit is combined with the current service credit. A member who is subject to the noncontributory pension benefit is entitled to combine the member’s prior eligibility service with the member’s current service if the member did not transfer to the Employees’ Pension System or Teachers’ Pension System from the Employees’ Retirement System or Teachers’ Retirement System after April 1, 1998.
