(1) In its April 2021 Update, the IFRS IC published a final agenda decision clarifying how to calculate the obligation relating to certain defined benefit plans under which the retirement benefit is (i) contingent on the employee being employed by the entity at the time of retirement; (ii) capped at a specified number of years of service; and (iii) linked to the employee's length of service at the date of retirement. In that decision, the IFRS IC took the view that the obligation should be recognized only over the years of service preceding the date of retirement in respect of which the employee generates entitlement to the benefit. The application of this decision has led to a change in accounting method, the effects of which should be taken into account retrospectively in accordance with IAS 8. However, as the Company considers the impact of this change of method on defined benefit obligation and the income statement to be insignificant, these impacts have not been restated for years prior to January 1, 2021. The effects of this change of method are therefore taken into account retrospectively as of January 1, 2021 in respect of 2020's and prior years defined benefit obligation. The adjustment at that date corresponds to a reduction in the 2020 commitments in the amount of €1,054 thousand. This reversal has been offset against previous reserves and retained earnings.
