Goodwill
Goodwill arising in a business combination is carried at cost as established at the acquisition date of the business less accumulated impairment losses, if any. For the purpose of impairment testing, goodwill is allocated to a unique cash generating unit (CGU).
Goodwill is not amortized and is reviewed for impairment at least annually or more frequently when there is an indication that the business may be impaired. If the recoverable amount of the business is less than its carrying amount, the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the business and then to the other assets of the business pro-rata on the basis of the carrying amount of each asset in the business. Any impairment loss for goodwill is recognized directly in profit or loss in the consolidated statement of income and other comprehensive income. An impairment loss recognized for goodwill is not reversed in a subsequent period.
