1.1 Consolidation
The Group accounts include the accounts of Smith & Nephew plc and its subsidiaries for the periods during which they were members of the Group.
Subsidiaries are entities controlled by the Group. The Group controls an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Subsidiaries are consolidated in the Group accounts from the date that the Group obtains control, and continue to be consolidated until the date that such control ceases. Intra-group balances and transactions, and any unrealised income and expenses arising from intra-group transactions, are eliminated on consolidation. All subsidiaries have year ends which are co-terminus with the Groups, with the exception of jurisdictions whereby a different year end is required by local legislation.
When the Group loses control over a subsidiary, it derecognises the assets and liabilities of the subsidiary and any related components of equity. Any resulting gain or loss is recognised in profit or loss. Any retained interest in the former subsidiary is measured at fair value.
