Other veri fi cations and information pursuant to legal and regulatory requirements Appointment of the Statutory Auditors We were appointed Statutory Auditors of Orano by the Annual General Meeting of May 24, 2018.

However, certain activities have a fi nite useful life (for example due to the fi nite mineral resources in the active or unused mines or the limited duration of the operating permits in nuclear activities); in this case, the cash flows taken into account to measure their value in use are not discounted to in fi nity, but rather to the end of their expected useful life. This impairment is calculated on the basis of the share of the net assets held at the end of the year. Receivables from equity investments are carried at their nominal amount. These investments are impaired, where applicable, to take the subsidiary’s fi nancial position into account. Estimating the value in use of equity interests requires management to exercise signi fi cant judgment in the choice of measurement methods and items to consider, which may be historical (particularly equity values) or projected (cash flow assumptions). Given the signi fi cant amount of equity interests, the judgment used to estimate values in use and the sensitivity of these values to changes in the data and assumptions on which they are based, we deemed the measurement of equity interests and related receivables to be a key audit matter. How our audit addressed this risk Our audit procedures mainly consisted in: ● examining, on the basis of the information provided by management, the measurement methods used by the Company; ● comparing the data used to test the equity interests for impairment with the subsidiaries’ accounting data, where applicable; ● gaining an understanding of the methodology and assumptions used to determine the value in use of the equity interests when said value takes into account the subsidiaries’ projected pro fi tability; ● verifying the arithmetical accuracy of the value in use calculations used by the Company; ● assessing, with the help of our experts, the sensitivity of the estimates of value in use used in the assumptions (particularly cash flow, discount rates and the long-term growth rate); ● assessing the recoverability of the related receivables in light of the analyses performed on the equity interests; and ● verifying the appropriateness of the disclosures provided in Notes 1.3, 2.2, 5.3 and 5.4 to the fi nancial statements.
