As at each balance-sheet date, the Group assesses whether there are indicators of impairment of any non-financial non-current assets. In the event of the determination that such indicators exist or in necessity of conducting an annual impairment test, the Group estimates the recoverable amount for a given asset or a cash-generating unit the asset is allocated to. Independently from the existence of the indicators, each year, the Group carries out impairment tests for intangible assets with an indefinite useful life and intangible assets not put into use.
The recoverable amount of an asset or of a cash-generating unit reflects the fair value of this asset or cash-generating unit less the costs of sale or value in use, whichever is higher. That recoverable amount is determined for individual assets, unless a given asset does not individually generate cash inflows being primarily independent from those generated by other assets or asset groups. Should the carrying amount of an asset be higher than its recoverable amount, impairment occurs and a write-down up to the determined recoverable amount is recognised. For the estimation of the value in use, the projected cash flows are discounted to their present value with the application of a discount rate prior to inclusion of the effects of taxation, which reflects the current estimated value of money in time as well as the risk typical for a given asset. Impairment losses for tangible assets utilised in the course of continuing operations are disclosed in a separate item of ‘Other operating costs’.
As at each balance-sheet date, the Group assesses whether there are indicators implying that the impairment loss of an asset other than goodwill, disclosed in the previous periods with regard to a given asset, is unnecessary, or whether it should be decreased. Should such indicators occur, the Group estimates the recoverable amount for the asset. The impairment loss recognised beforehand is reversed only and exclusively if, from the time when the last impairment loss was recognised, there has been a change of the estimated values applied to determine the recoverable amount of a given asset. In such event, the carrying amount of the asset is increased up to the level of its recoverable amount. The increased amount cannot exceed the carrying amount of the asset, which would have been determined (after amortisation deduction), had no impairment been reflected in the previous years on account of loss of value in reference to that asset. The reversal of the impairment loss for an asset is recognised immediately as revenue in profit or loss. Following the reversal, in the subsequent periods, the depreciation charge for a given asset is adjusted in a manner which allows for, within the remaining useful life of the asset in question, systematic write-down of its verified carrying amount decreased for the exit value. The impairment loss recognised for goodwill is not reversed in further periods.
