2.8 Significant accounting policies (a) Business combinations and goodwill Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred, which is measured at acquisition date fair value, and the amount of any non-controlling interests in the acquiree. For each business combination, the Company elects whether to measure the non-controlling interests in the acquiree at fair value or at the proportionate share of the acquiree’s identifiable net assets. Acquisition-related costs are expensed as incurred with one exception. The costs to issue debt or equity securities shall be recognised in accordance with IAS 32 and IFRS 9. When the Company acquires a business, it assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as at the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquiree. Any contingent consideration to be transferred by the acquirer is recognised at fair value at the acquisition date. Goodwill is initially measured at cost (being the excess of the aggregate of the consideration transferred and the amount recognised for non-controlling interests and any previous interest held over the net identifiable assets acquired and liabilities assumed). If the fair value of the net assets acquired is in excess of the aggregate consideration transferred, the Company reassesses whether it has correctly identified all of the assets acquired and all of the liabilities assumed and reviews the procedures used to measure the amounts to be recognised at the acquisition date. If the reassessment still results in an excess of the fair value of net assets acquired over the aggregate consideration transferred, then the gain is recognised in profit or loss. After initial recognition, goodwill is measured at cost less any accumulated impairment losses. Goodwill is thereafter assessed for impairment on an annual basis. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of the Company’s cash-generating units that are expected to benefit from the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to those units. Where goodwill has been allocated to a cash-generating unit (CGU) and part of the operation within that unit is disposed of, the goodwill associated with the disposed operation is included in the carrying amount of the operation when determining the gain or loss on disposal. Goodwill disposed in these circumstances is measured based on the relative values of the disposed operation and the portion of the cash-generating unit retained. (b) Investments in subsidiaries Subsidiaries are fully consolidated in the Group’s financial statements from the date control is obtained by the Group until the date that control ceases. Separate financial statements of the investor In the separate financial statements of the Company, investments in subsidiaries are carried at cost, net of any impairment. Where the carrying amount of an investment is greater than its estimated recoverable amount, it is written down immediately to its recoverable amount and the difference is recognised in profit or loss. Upon disposal of the investment, the difference between the net disposal proceeds and the carrying amount is recognised in profit or loss. For basis of consolidation, refer to Note 2.3 (c) Investments in associates An associate is an entity over which the Company has significant influence but not control, or joint control, generally accompanying a shareholding between 20% and 50% of the voting rights. (i) Separate financial statements of the investor In the separate financial statements of the investor, investments in associates are carried at cost (which includes transaction costs). Where the carrying amount of an investment is greater than its estimated recoverable amount, 109 OUR YEAR AT A GLANCE OUR PEOPLE GOVERNANCE FINANCIAL STATEMENTS
