5 2020 CONSOLIDATED FINANCIAL STATEMENTS

Statutory Auditors’ report on the consolidated financial statements

Our response Our work consisted primarily of: reviewing the compliance of the methodology used by the Group p with applicable accounting standards; assessing the reasonable nature of assumptions used to p determine future cash flows in relation to operating data, with regard to the business and financial context for the Group’s operations, and their consistency with the most recent estimates presented to the Board of Directors within the framework of budgetary processes; assessing, with the help of our valuation experts, the consistency p of the perpetual growth rate and the weighted average unit cost of capital in all components; analysing the sensitivity of the value in use determined by p management to a change in the main assumptions made. Lastly, we verified that Note 10.2 to the consolidated financial statements provided appropriate information. Post-employment benefits mainly concern the Group’s obligations towards its employees to provide retirement bonuses in France and defined-benefit pension plans in the United Kingdom, Germany and other European countries (Belgium and Norway). The actuarial value of accumulated benefits as at 31 December 2020 was €390.4 million. The net liability in respect of retirement benefits and similar obligations was calculated at the balance sheet date based on the most recent valuations available. Since these liabilities are covered by plan assets with a fair value of 1,717.8 million, the net liability at 31 December 2020 totalled €380.1 million. The most significant plan assets concern the United Kingdom and France. Valuing pension plan assets and liabilities, as well as the actuarial cost for the financial year, requires a high level of judgment by management to determine appropriate assumptions to be made, such as the discount rate, inflation, future pay rises, staff turnover and mortality tables. The change in some of these assumptions may have a material impact on determining the net liability recognised as well as on the Group’s profit. In view of the amounts represented by these obligations and associated plan assets, as well as the technical skill required to evaluate these amounts, we considered this type of post-employment benefit obligations to be a key audit matter. Our response We familiarised ourselves with the process for valuing post-employment benefit obligations implemented by the Group. A review of actuarial assumptions was performed by: assessing the discount rate and inflation in order to evaluate their p consistency with market conditions; assessing the reasonable nature of assumptions relating to pay p rises, staff turnover and mortality in order to evaluate their consistency with the specific characteristics of each plan and, where applicable, with national and sector benchmarks; %$() "%!$." #) # ) $ ! ) $#( (Note 5.3.1 to the consolidated financial statements) Risk identified
