| (b) | Basis of consolidation |
The consolidated financial statements comprise the Company and its subsidiaries and the Group’s interests in associates.
A subsidiary is an entity controlled by the Company. When fulfilling the following conditions, the Company has control over an entity: (a) has power over the investee, (b) has exposure, or rights, to variable returns from its involvement with the investee, and (c) has the ability to use its power over the investee to affect the amount of the investor’s returns.
When assessing whether the Company has power over that entity, only substantive rights (held by the Company and other parties) are considered.
The financial results of subsidiaries are included in the consolidated financial statements from the date that control commences until the date that control ceases, and the profit attributable to non-controlling interests is separately presented on the face of the consolidated statement of comprehensive income as an allocation of the profit or loss for the year between the non-controlling interests and the equity holders of the Company. Non-controlling interests represent the equity in subsidiaries not attributable directly or indirectly to the Company. For each business combination, the Group measures the non-controlling interests at the proportionate share, of the acquisition date, of fair value of the subsidiary’s net identifiable assets. Non-controlling interests at the end of the reporting period are presented in the consolidated statement of financial position within equity and consolidated statement of changes in equity, separately from the equity of the Company’s equity holders. Changes in the Group’s interests in a subsidiary that do not result in a loss of control are accounted for as equity transactions, whereby adjustments are made to the amounts of controlling and non-controlling interests within consolidated equity to reflect the change in relative interests, but no adjustments are made to goodwill and no gain or loss is recognized. When the Group loses control of a subsidiary, it is accounted for as a disposal of the entire interest in that subsidiary, with a resulting gain or loss being recognized in profit or loss. Any interest retained in that former subsidiary at the date when control is lost is recognized at fair value and this amount is regarded as the fair value on initial recognition of a financial asset or, when appropriate, the cost on initial recognition of an investment in an associate or a joint venture.
An associate is an entity, not being a subsidiary, in which the Group exercises significant influence, but not control, over its management. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies.
An investment in an associate is accounted for in the consolidated financial statements under the equity method and is initially recorded at cost, adjusted for any excess of the Group’s share of the acquisition-date fair values of the investee’s net identifiable assets over the cost of the investment (if any) after reassessment. Thereafter, the investment is adjusted for the Group’s equity share of the post-acquisition changes in the associate’s net assets and any impairment loss relating to the investment. When the Group ceases to have significant influence over an associate, it is accounted for as a disposal of the entire interest in that investee, with a resulting gain or loss being recognized in profit or loss. Any interest retained in that former investee at the date when significant influence is lost is recognized at fair value and this amount is regarded as the fair value on initial recognition of a financial asset.
All significant intercompany balances and transactions and unrealized gains arising from intercompany transactions are eliminated on consolidation. Unrealized gains arising from transactions with associates are eliminated to the extent of the Group’s interest in the entity. Unrealized losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment.
