92. Any amount determined pursuant to subparagraph 4 of the second paragraph of section 137 of the Act shall, within 5 years after the date of the actuarial valuation, be paid into the pension fund by the active members.
Section 128 and the first and second paragraphs of section 129 of the Act as well as section 81 of the Regulation apply, with the necessary modifications and as the case may be, to the determination or payment of such amount. Unless the pension plan sets a higher interest rate, any amount so determined and not paid into the pension fund bears interest, from the last day of the month following that for which it should have been paid, at the rate of return of the pension fund.
Such amount may be used to reduce proportionately and in accordance with section 91 the amortization amounts which, 5 years after the date of the actuarial valuation, remain to be paid in respect of any actuarial deficiency.
