Impairment of non-financial assets

The Group evaluates the carrying value of assets with finite useful lives when events and circumstances indicate that the carrying value may not be recoverable and when there are indicators of impairment. Intangible assets that have an indefinite useful life are not subject to amortisation. These assets are tested annually for impairment and more frequently when events or circumstances indicate that there may be impairment.

An impairment loss is recognised in the income statement when the carrying amount of an asset exceeds its recoverable amount. An asset's recoverable amount is the higher of the fair value less cost of disposal (the amount obtainable from the sale of an asset in an arm's-length transaction between knowledgeable willing parties), or its value-in-use. Value-in-use is the present value of estimated future cash flows expected to arise from the continuing use of an asset and from its disposal at the end of its useful life. The estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows.

An impairment loss recognised for an asset, other than goodwill, in prior years is reversed if there has been a change in the estimates used to determine the asset's recoverable amount since the last impairment loss was recognised and the recoverable amount exceeds the new carrying amount. The reversal of the impairment is limited to the carrying amount that would have been determined (net of depreciation or amortisation) had no impairment loss been recognised in prior years. The reversal of such an impairment loss is recognised in the income statement in the same line item as the original impairment charge.
