10. The actuarial valuation must determine an amount, called “financial crisis amount”, equal to the result of the following formula, which may not be negative:
D - E
“D” represents the market value of the assets of the pension plan on 31 December 2007, adjusted to 31 December 2008 taking into account receipts and expenditures of the pension plan fund and using the interest rate that applied on 31 December 2007 to establish, on a solvency basis, the value of the benefits of members in the plan to whom no pension was paid on that date;
“E” represents the market value of the assets of the plan on 31 December 2008.
The market value of the assets of the plan referred to in elements “D” and “E” of the first paragraph is reduced by the value of the pension guaranteed, the value of the voluntary contributions and the optional ancillary contributions paid to the pension fund and the value of the contributions paid under provisions which, in a defined benefit plan, are identical to those of a defined contribution plan.
Where applicable, the financial crisis amount bears interest, between 31 December 2008 and the valuation date, at the rate used to calculate element “D”.
