91. Where the member contribution provided for under the plan is greater than that required pursuant to section 79, the excess thereof may serve to reduce, in the following order, the amounts remaining to be paid in connection with:
(1) (subparagraph revoked);
(2) any technical actuarial deficiency.
(3) any improvement unfunded actuarial liability.
The reduction must, where applicable, be made at the time of the first actuarial valuation of the whole pension plan that follows the payment of excess contributions.
If the excess is insufficient to eliminate an unfunded liability or an amount referred to in the first paragraph, the reduction shall be applied proportionately to each amount remaining to be paid. In addition, if there is more than one liability or amount, the reduction shall be applied from the earliest to the most recent.
