Impairments of intangible assets and property, plant and equipment—Impairments are identified by comparing the carrying amount with the recoverable amount. If no future cash flows generated independently of other assets can be allocated to individual assets, recoverability is assessed on the basis of the CGU to which the assets can be allocated. At each reporting date, the Group assesses whether there is any indication that an asset may be impaired. If any such indication exists, the recoverable amount of the asset or CGU must be determined. In addition, at the end of each period the Group assesses whether there is any indication that an impairment loss recognized in prior periods for an asset other than goodwill no longer exists or may be decreased. If the impairment loss is reversed, the carrying amount of the asset (or a CGU) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or CGU) in prior years.
