Impairment of non-financial assets
Property, plant and equipment and intangible assets are tested for impairment when there are indications of impairment. Impairment tests are based on the comparison of the carrying amount of an asset (or cash-generating unit if the asset does not independently generate separate cash inflows) with its recoverable amount, equal to the higher of its fair value less cost to sell and value in use.
If the recoverable amount is lower than the carrying amount of an asset (or cash-generating unit), the carrying amount is decreased to the recoverable amount of the asset (or cash-generating unit). An impairment loss is recognised as cost of the period in which the impairment loss arose.
