Impairment of non-financial assets
Assets that have an indefinite useful life are not subject to amortization and are tested annually for impairment. Assets that are subject to amortization or depreciation are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use.
Assets other than goodwill that suffered impairment are reviewed for possible reversal of the impairment at each reporting date.
