67.4. The remuneration paid during the period beginning with the payment of a benefit referred to in this subdivision and ending on the date on which the payment of the retirement pension begins or begins again, or the date the member reaches 65 years of age, whichever occurs first, may not be taken into consideration for the calculation of the benefits relating to credited service that does not relate to that period, unless it is to the advantage of the member.
Also, the following adjustments apply:
(1) in the case referred to in subparagraph 1 of the first paragraph of section 67.3, if contributions are paid during that period, the member is entitled to an additional pension determined in accordance with the rules set forth in section 78 for the calculation of the minimum value of the pension resulting from the contributions paid during a postponement period. In addition, if the retirement pension of the member was reduced by reason of payment having begun before the normal retirement age, the reduction must be recalculated at the end of the suspension of payment provided for in section 67.3; and
(2) in the case referred to in subparagraph 2 of the first paragraph of section 67.3, if contributions were paid during that same period, the member is entitled to a pension that cannot be less than the pension resulting from the application of the rules set forth in section 78.
The adjustments provided for in the second paragraph also apply to the benefits referred to in section 83 or 104, the payment of which was suspended under the fourth paragraph of section 67.3.
