Impairment of non-financial assets
Internal and external sources of information are reviewed at the end of each reporting period to identify indications that the following assets may be impaired or, except in the case of goodwill, an impairment loss previously recognized no longer exists or may have decreased:
| • |
property, plant and equipment |
| • |
prepaid lease payments; and |
| • |
intangible assets. |
If any such indication exists, the recoverable amount of the asset is estimated. In addition, for intangible assets that have indefinite useful lives, the recoverable amount is estimated annually whether or not there is any indication of impairment.
The recoverable amount of an asset is the greater of its fair value less costs of disposal and value in use. 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. Where an asset does not generate cash inflows largely independent of those from other assets, the recoverable amount is determined for the smallest group of assets that generates cash inflows independently (i.e. a cash-generating unit).
An impairment loss is recognized in profit or loss whenever the carrying amount of an asset, or the cash-generating unit to which it belongs, exceeds its recoverable amount. Impairment losses recognized in respect of cash-generating units are allocated first to reduce the carrying amount of any goodwill allocated to the cash-generating unit (or group of units) and then, to reduce the carrying amount of the other assets in the unit (or group of units) on a pro rata basis, except that the carrying amount of an asset will not be reduced below its individual fair value less costs of disposal (if measurable) or value in use (if determinable).
An impairment loss is reversed if there has been a favorable change in the estimates used to determine the recoverable amount.
A reversal of an impairment loss is limited to the asset’s carrying amount that would have been determined had no impairment loss been recognized in prior years. Reversals of impairment losses are credited to profit or loss in the year in which the reversals are recognized.
