FINANCIAL INFORMATION ON THE ASSETS, FINANCIAL POSITION AND CONSOLIDATED FINANCIAL STATEMENTS 20 GROUPE ADP CONSOLIDATED FINANCIAL STATEMENTS AS OF 31 DECEMBER 2018

The underlying estimates and assumptions are based on historical experience and on the basis of the information available, or situations prevalent at the date of preparation of the accounts. Depending on changes in those assumptions and situations, estimated amounts accounted in the financial statements could differ from actual values. Such estimates and assumptions used for the preparation of the financial statements concern essentially: ◆ the valuation of the fair value of the assets acquired and the liabilities assumed in the context of the business combination (see Note 2.1); ◆ pension plans and other post-employment benefits (see Note 5); ◆ the fair value of investment property (see Note 6.3.2); ◆ the valuation of the recoverable value of intangible, tangible assets, and investment properties (see Note 6.4) and on other non-current assets, particularly the investments accounted for under the equity method (see Note 4.9.2); ◆ provisions for risks and litigations (see Note 8). 1.2 Accounting policies Adopted IFRS as endorsed by the EU The Group’s financial statements are prepared in accordance with International Financial Reporting Standards (IFRS) and IFRIC interpretations as adopted by the European Union as at 31 December 2018. These standards are available on the European Commission’s web site at the following address: http://ec.europa.eu/internal_market/accounting/ias/index_fr.htm. These accounting principles do not differ from the International Financial Reporting Standards issued by the IASB, insofar as the standards and interpretations published by the IASB, but have not yet been approved by the European Union, do not have any significant impact on the consolidated financial statements of Groupe ADP. Standards, amendments and interpretations that have been endorsed by the EU and mandatory as from 1 January 2018 Standards and amendments effective on 1 January 2018 and that have not been applied earlier by the Group are the following: ◆ IFRS 15 – Revenue from contracts with customers (issued in May 2014) and amendments to IFRS 15 (issued in September 2015). This standard replaces IAS 18, Revenue and IAS 11, Construction Contracts. This standard has been endorsed by the regulation (UE) on 22 September 2016; ◆ Clarifications to IFRS 15 (issued in April 2016). The objective of this project is to clarify the guidance in IFRS 15 in respect of issues arising from the discussions of the TRG (Transition Resource Group). These topics are mainly related to the identification of performance obligations, distinction between principal versus agent and licenses. This standard has been endorsed by the regulation (UE) on 31 October 2017; ◆ IFRS 9 Financial Instruments (issued in July 2014). This standard deals with classification and measurement of financial instruments, impairment of financial instruments and hedge accounting. IFRS 9 replaces IAS 39 Financial Instruments and has been endorsed by the regulation (UE) on 22 November 2016; ◆ IFRIC Interpretation 22 – Foreign Currency Transactions and Advance Consideration (issued on December 2016); ◆ Amendments to IAS 40 – Transfers of Investment Property (issued on December 2016);

◆ Amendments to IFRS 2 – Classification and measurement of share- based payment transactions (issued in June 2016); ◆ Annual improvements to IFRS Standards 2014-2016 Cycle (issued in December 2016). The analysis of the impacts of IFRS 9 and IFRS 15 on the ADP scope as at 1 January 2018 is disclosed in Note 1.3. The remaining standards, amendments and interpretations mentioned above do not have a significant impact on the consolidated financial statements of the Group. Standards, amendments and interpretations that have been endorsed by the EU and applicable after 1 January 2018 and not early adopted by the Group The Group has not applied the following standards, amendments and interpretations that are not applicable in 2018 but should subsequently be mandatory: ◆ IFRS 16 – Leases (issued in January 2016). This standard will replace the standard IAS 17 as well as related IFRIC 4 Interpretation, SIC 15 and SIC 27. This standard must be applied from 2019 onwards; ◆ IFRIC 23 – Uncertainty over income tax treatment (issued in June 2017). This interpretation clarifies the application of IAS 12 – Income taxes regarding the accounting and valuation of income tax when it is subject to uncertainty. This interpretation must be applied from 2019 and subsequent years subject to its endorsement by EU on 23 October 2018; ◆ Amendments to IAS 28 – Long-term interests in associates and joint- ventures. These amendments should be mandatory for the 2019 and subsequent years subject to its endorsement by EU; ◆ Amendments related to Annual improvements to IFRS Standards 2015- 2017 Cycle (issued in December 2017); ◆ Amendments to IAS 19 – Plan Amendment, Curtailment or Settlement (issued in February 2018). These amendments must be applied as from 1 January 2019 onwards subject to their endorsement by the EU; ◆ Amendments to references to the conceptual framework in IFRS standards (issued in March 2018). These amendments must be applied as from 1 January 2020 subject to their endorsement by the EU; ◆ Amendments to IFRS 9 – Prepayment features with negative compensation (issued in October 2017). These amendments must be applied as from 1 January 2019; ◆ Amendments to IFRS 3 – Definition of a business, (issued on 22 October 2018). These amendment must be applied as from 1 January 2020 subject to their endorsement by the EU; ◆ Amendments to IAS 1 and IAS 8: definition of material (issued in October 2018). This amendments must be applied as from 1 January 2020 subject to their endorsement by the EU. Estimated impacts of standards effective as from 2019 IFRS 16 “Leases” will be applied by the Group as of 1 January 2019. This standard modifies the accounting treatment of leases contracts, mainly for lessees, which have to recognize an asset (right of use) and a liability (lease dept) for all lease contracts, except for short term leases and leases which the underlying asset is of low value. This standard will replace IAS 17 and its related interpretations. In 2018, the Group has analyzed all leases and has decided to apply IFRS 16 using the retrospective “modified” method. The impact of the application of this standard as described below mainly concerns contracts for which the Group is a lessee, the effects of the application of the standard being limited for lease contracts in which the Group is a lessor.
