Given the nature of Group’s assets and operations, most of its individual assets do not generate cash inflows independently from other assets. The Group identifies a single major CGU (see Note 9). For the purpose of impairment testing the Group allocates the whole goodwill to this CGU. In accordance with IFRS 3 “Business Combinations”, goodwill is not amortised but is tested for impairment at least once a year or more frequently when there is an indication that it may be impaired. IAS 36 “Impairment of Assets” requires these tests to be performed at the level of the cash generating unit (CGU). Recoverable amount To determine whether an impairment loss should be recognised, the carrying value of the assets and liabilities of the CGU, including allocated goodwill, is compared to its recoverable amount. The recoverable amount of a CGU is the higher of its fair value less costs to sell and its value in use. Fair value less costs to sell is the best estimate of the amount realisable from the sale of a CGU in an arm’s length transaction between knowledgeable, willing parties, less the costs of disposal. This estimate is determined on the basis of available market information taking into account specific circumstances. Value in use is the present value of the future cash flows expected to be derived from the CGU, including goodwill. Cash flow projections are based on economic and regulatory assumptions, telecommunications licences renewal assumptions and forecast trading conditions drawn up by the Group management, as follows: If the recoverable amount of the CGU is less than its carrying amount, an impairment loss is recognised in the amount of the difference. The impairment loss is firstly allocated to reduce the carrying amount of goodwill and then to the other assets of CGUs. Goodwill impairment losses are recorded in the income statement as a deduction from operating income/loss and are not reversed.
