24. On the date on which the valuation of the benefits of members or beneficiaries affected by the withdrawal of an employer that is a party to a multi-employer pension plan is made, the amount referred to in the third paragraph of section 188.8.131.52 of the Act is equal, at the time the assets of the plan are apportioned, to element SR in the following formula:
A + B - C = SR
“A” represents the amount in question established on the date of the last actuarial valuation;
“B” represents the amortization payment determined, on the date of the last actuarial valuation, for the financial crisis deficit;
“C” represents the amount by which the employer contribution paid since the date of the last actuarial valuation exceeds the employer contribution that would have been determined on that date, if the amount referred to in subparagraph b of paragraph 2 of the first paragraph of section 39 of the Act referred to in paragraph 3 of section 4 had been equal to the amount determined in accordance with paragraph 1 of section 21 increased by the value of the special amortization payments required since the date of the last actuarial valuation.
On the date of the valuation of the benefits of members and beneficiaries mentioned in the first paragraph, the amount referred to in the third paragraph of section 184.108.40.206 of the Act corresponds, after the assets of the plan have been distributed, to element “S” in the following formula:
SR - (X - Y) = S
“SR” represents element `SR´ determined pursuant to the first paragraph;
“X” represents the value of the portion of the plan’s assets that would be allocated to the group of benefits of those members and beneficiaries at the time of the distribution provided for in section 222 of the Act, were the assets of the plan, for the distribution, increased by element “SR” determined pursuant to the first paragraph;
“Y” represents the value of the portion of the assets allocated to that group at the time of the distribution.
Those amounts and contributions bear interest at the rate of return of the pension fund. Should the date of the last actuarial valuation or the date of the valuation of the benefits of the members and beneficiaries not correspond to the date of the end of a fiscal year of the plan, only the monthly payments related to amortization payments, current service contributions and the special amortization payments that became due during the period starting the day following the last actuarial valuation and ending on the date of the valuation of benefits are taken into account.
