The carrying amounts of non-current assets (or CGUs) are reviewed whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If any such indicator of impairment exists, the recoverable amount of the asset is estimated as the higher of the fair value less costs of disposal and the value in use.
For an asset that does not generate cash inflows largely independent of those from other assets, the recoverable amount is determined for the CGU to which the asset belongs. An impairment loss is recognised whenever the carrying amount of the CGU exceeds its recoverable amount.
A previously recognised impairment loss is reversed (or partially reversed) if there has been a change in the estimates used to determine the recoverable amount, however, not to an amount higher than the carrying amount that would have been determined (net of depreciation and amortisation) had no impairment loss been recognised in prior years. Assets previously impaired are reviewed for possible reversal of impairment at each reporting period.
Goodwill is tested annually for impairment (refer note 10.2.1 for related policy).
Impairment charges are presented on the face of the statement of comprehensive income:
| (i) | within net operating profit when the impairment relates to non-current operating assets of the group; |
| (ii) | alongside share of income of equity accounted investments when the impairment relates to associates and joint ventures. |
