60.10. The duration of the liabilities is established by the actuary responsible for carrying out the actuarial valuation using the following formula:(P- – P+) / (2 * P * 0,01 )
where
“P” is the value of the liabilities on a funding basis, as at the date of the actuarial valuation, established using the discount rate determined by the actuary;
“P-” is the same value of the liabilities established using the discount rate minus 1%;
“P+” is the same value of the liabilities established using the same discount rate plus 1%.
For the application of this section, the liabilities of the plan must be increased by the value of the additional obligations resulting from any amendment considered for the first time at the date of the actuarial valuation of the plan.
In the case of a target-benefit plan, the plan’s liabilities are determined before the application of recovery measures, the restoration of benefits or the appropriation of surplus assets provided for in the actuarial valuation. In addition, the value of the additional obligations resulting from any amendment considered for the first time at the date of the actuarial valuation of the plan must not be taken into account.
