319.3. The payment made in accordance with section 143 and, if applicable, section 145.1 before 31 December 2014 in respect of a plan subject to Chapter X.2 constitutes the final payment of the benefits accrued to the member or beneficiary concerned.
The employer may however pay an additional amount into the pension fund for the payment of all or part of any amount that is no longer required to be paid under the first paragraph.
A pension plan may also be amended to provide for the payment, in any fiscal year of the plan ending before 1 January 2020, of amounts whose payability is extinguished under the first paragraph. The amount of such a payment, added to the sum of the amounts referred to in section 146.12, must not result in insufficient contributions being made to the plan.
