23. The years or parts of a year of service contemplated in the first paragraph of section 22 which are standing to the credit of an employee who, on 31 December 1987, was not a peace officer included in the bargaining unit referred to in section 1 or who, on 31 December 1991, was not an intermediate officer holding employment in a house of detention or a person belonging to a class or subclass of employees determined under subparagraph 2 of the first paragraph of section 1.1, and the years and parts of a year of service referred to in the second paragraph of section 22 shall be credited under this plan on an actuarially equivalent basis as established on the date he begins to pay contributions to this plan. These years and parts of a year of service shall, in that case, be credited, beginning with the latest service, until the actuarial value of the benefits as established in respect of those years and parts of a year of service under this plan reaches the actuarial value of the benefits accrued under the other pension plan, without exceeding the service credited to the employee under that other plan.
The actuarial values of the benefits shall be determined on the basis of actuarial assumptions and methods determined by regulation, which may vary according to the pension plans and benefits concerned.
Notwithstanding the foregoing, if years and parts of a year of service contemplated in the first paragraph of section 22 are standing to the credit of the employee under several pension plans, they are deemed, for the purposes of establishing the actuarial value of accrued benefits, to have been transferred to the last pension plan of which the employee was a member before becoming a member of this plan.
