(i)goodwill

Goodwill represents the excess of the cost of an acquisition over the fair value of the Group's share of fair value of the net identifiable assets of the acquired subsidiaries at the date of acquisition. Goodwill on acquisitions of subsidiaries is included in intangible assets. Goodwill impairment reviews are undertaken annually or more frequently if events or changes in circumstances indicate a potential impairment. The carrying value of goodwill is compared to the recoverable amount, which is the higher of value in use and the fair value less costs to sell. Any impairment is recognized immediately as an expense and is not subsequently reversed.

Goodwill is allocated to cash-generating units for the purpose of impairment testing. The allocation is made to those cash-generating units or groups of cash-generating units that are expected to benefit from the business combination in which the goodwill arose identified according to the operating segment.

(ii) Trademarks

Acquired trademarks have an infinite useful life and are carried at historical cost without amortization. Trademarks are tested annually for impairment, or more frequently if events or changes in circumstances indicate that it might be impaired and carried at cost less accumulated impairment losses.
