Goodwill is the excess of the aggregate of the consideration transferred over the fair value recognized for the acquisition of the net value of the identifiable net assets acquired and liabilities assumed. If the fair value of the net assets acquired exceeds the aggregate consideration transferred, then the gain is recognized in the consolidated statement of income.
After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of the Group’s cash-generating units (CGU) that are expected to benefit from the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to these units.
Where goodwill has been allocated to a CGU and part of the operation within that unit is disposed of, the goodwill and the assets disposed of are included in the carrying amount of the operation when determining the gain or loss on disposal. Goodwill disposed of in these circumstances is measured based on the relative values of the disposed operation and the portion of the cash-generating unit retained.
Impairment is determined for goodwill by assessing the recoverable amount of each CGU (or group of CGUs) to which the goodwill relates. Where the recoverable amount of the CGU is less than its carrying amount, an impairment loss is recognized. Impairment losses relating to goodwill cannot be reversed in future periods.
