13. Where, further to an amendment to a pension plan made before the date determined in accordance with section 36 with regard to the plan, an actuarial valuation determines the value of additional obligations of the affected component of the pension plan, a special amortization payment is determined.
That payment corresponds to the higher of the value of the additional obligations determined on a solvency basis or their value determined on a funding basis.
The special amortization payment must be paid as soon as the report on the first actuarial valuation considering the amendment is sent to Retraite Québec. To such sum shall be added accrued interest, if any, from the date of the valuation, calculated at the rate referred to in section 48 of the Act.
For the purposes of the Act, the special amortization payment is considered the special amortization payment provided for in section 132 of the Act.
