3.10 Impairment of tangible and intangible assets
At the end of the fiscal year, the Group reviews the carrying amounts of its tangible and intangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any such indications exist, the recoverable amounts of the assets is estimated in order to determine the impairment loss (if any).
The Group estimated the recoverable amount of the cash-generating unit to which the asset belongs. Recoverable amount is the higher of 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 at year-end of the time value of money considering the risks specific to the asset.
Intangible assets not yet available for use are tested for impairment at least annually, and whenever there is an indication that the asset may be impaired.
If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying amount, the carrying amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognized immediately in profit or loss.
When an impairment loss subsequently reverses, the carrying amount of the asset (or a cash-generating unit) 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 cash-generating unit) in prior years. A reversal of an impairment loss is recognized immediately in profit or loss.
