1.3.3 Consolidation methods Subsidiaries

Entities over which the group exercises exclusive control are fully consolidated. Control by the group over its subsidiaries is based on its exposure or entitlements to variable income resulting from its investment in these entities, as well as its ability to exercise power over the entity in such a way as to influence the amount of the returns it receives. However, in cases where the consolidation of an entity (or a group of entities) represents an insigni fi cant interest in terms of providing a true and fair report, the group has chosen not to consolidate it. Intra-group balances and transactions are eliminated. The acquisition date from which the group consolidates the fi nancial statements of the acquiree is the date of its effective takeover. Non-controlling interests in the net assets of consolidated subsidiaries are presented on a separate line of equity under “non controlling interests.” Non-controlling interests include the amount of minority interests as of the acquisition date and the amount represented by minority interests in the change in equity since that date. In the absence of a binding agreement, the negative results of subsidiaries are systematically allocated to equity attributable to the owners of the parent company and to non-controlling interests, based on their respective percentage interests, even if the latter become negative. Transactions with non-controlling interests, without impact on control, are treated as transactions with group shareholders and are recorded in equity. Joint ventures and associates An associate is an entity over which the group exercises signi fi cant influence. Signi fi cant influence is the power to influence the making of key fi nancial and operational decisions within the entity, without this demonstrating control or joint control of the group. A joint venture is a joint arrangement in which the parties, who exercise joint control, are entitled to a share of the net assets of the joint venture. Joint control is demonstrated when, on the basis of the rights provided for by this agreement, decisions on the relevant activities of the entity require the unanimous agreement of the parties. The factors taken into account to demonstrate signi fi cant influence or joint control are similar to those used for analyzing the group’s control over its subsidiaries. Joint ventures and associates are accounted for using the equity method. Interests in joint operations A joint operation is a partnership in which the partners (joint owners), who exercise joint control over the entity, have direct rights over the assets of the entity, and obligations in respect of its liabilities. As a co-investor, the group recognizes the relevant assets and liabilities line by line, as well as the income and expenses related to its interests in the joint operations.
