The group assesses at each reporting date whether there is an indication that the carrying value of an asset or a CGU may be impaired. If any such indication exists, or when annual impairment testing for an asset is required, the group makes an estimate of the asset’s recoverable amount. Where the carrying amount of an asset exceeds its recoverable amount, the asset/CGU is considered impaired and is written down to its recoverable amount. In assessing value-in-use, 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. Impairment losses of continuing operations are recognised in the income statement in those expense categories consistent with the function of the impaired asset/CGU.
An assessment is made at each reporting date as to whether there is any indication that previously recognised impairment losses may no longer exist or may have decreased. If such indication exists, the recoverable amount is
re-estimated. A previously recognised impairment loss is reversed only if there has been a change in the estimates used to determine the asset’s/CGU’s recoverable amount since the last impairment loss was recognised, in which case the carrying amount of the asset/CGU is increased to its recoverable amount. That increased amount cannot exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognised for the asset/CGU in prior years. Such reversal is recognised in profit or loss, and the depreciation charge is adjusted in future periods to allocate the asset’s revised carrying amount, less any residual value, on a systematic basis over its remaining useful life. |
