74. If, at the time of a refund of contributions, amounts have been paid as pension benefits and additional benefits under this plan or under another pension plan out of which service has not been transferred to this plan on an actuarially equivalent basis, the total amount of the contributions including accrued interest up to the date on which pension benefits and additional benefits became payable is reduced by the amounts paid as pension benefits from the date on which the benefits ceased to be paid. Following the death of a beneficiary of a pension, the balance of the contributions and of any accrued interest bears interest, compounded annually, at the rate determined in Schedule III in force on the first day of the month following the death and computed from that date. In addition, for every period during which no benefit was paid, the balance of the contributions and of any accrued interest, established on the first day of the period, bears interest, compounded annually, at the rates determined in Schedule II.
However, if pension benefits are payable under section 57, the contributions refunded under section 70 do not include contributions relating to service credited for the purpose of computing those pension benefits. In that case, the first paragraph applies, at the time the pension benefits become payable, in respect of other contributions but without taking into account the amounts paid as pension benefits under section 57. From the time the pension benefits cease to be paid, the first paragraph once again applies to the contributions and amounts paid as pension benefits not taken into account for the purpose of the initial refund.
For the purposes of this section, contributions do not include amounts paid for the acquisition of pension credits under sections 41.1 to 41.5. However, with respect to those amounts, section 59 of the Act respecting the Government and Public Employees Retirement Plan (chapter R-10) applies with the necessary modifications.
