2. Summary of significant accounting policies (cont'd.) 2.5 Property, plant and equipment (cont'd.) Residual values, where applicable, are reviewed annually against prevailing market rates at the balance sheet date for equivalent aged assets and depreciation rates are adjusted accordingly on a prospective basis. For the current financial year ended 31 December 2020, the estimated residual value for aircraft airframes and engines excluding service potential is 10% of their cost (2019: 10% of their cost). An element of the cost of an acquired aircraft is attributed on acquisition to its service potential, reflecting the maintenance condition of its engines and airframes. This cost, which can equate to a substantial element of the total aircraft cost, is amortised over the shorter of the period to the next checks or the remaining life of the aircraft. At the end of the reporting period, the Group assesses whether there is any indication of impairment. If such an indication exists, an analysis is performed to assess whether the carrying amount of the asset is fully recoverable. A write down is made if the carrying amount exceeds the recoverable amount. See accounting policy Note 2.8 on impairment of non-financial assets. Gains and losses on disposals are determined by comparing proceeds with the carrying amount and are included in profit or loss. Deposits on aircraft purchase are recognised as deposits and subsequently included as part of the cost of the aircraft and are depreciated from the date that aircraft is ready for its intended use. 2.6 Intangible assets 2.6.1 Goodwill Goodwill arises from a business combination and represents the excess of the aggregate of fair value of consideration transferred, the amount of any non-controlling interest in the acquiree and the fair value of any previous equity interest in the acquiree over the fair value of the net identifiable assets acquired and liabilities assumed on the acquisition date. If the fair value of consideration transferred, the amount of non-controlling interest and the fair value of previously held interest in the acquiree are less than the fair value of the net identifiable assets of the acquiree, the resulting gain is recognised in profit or loss. Goodwill is not amortised but it is tested for impairment annually or more frequently if events or changes in circumstances indicate that it might be impaired, and carried at cost less accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a business combination is allocated to each of the cash generating units (“CGUs”), or groups of CGUs, that is expected to benefit from the synergies of the combination. Each unit or group of units to which the goodwill is allocated represents the lowest level within the entity at which the goodwill is monitored for internal management purposes. Goodwill is monitored at operating segment level. The carrying value of goodwill is compared to the recoverable amount, which is the higher of value in use and the fair value less costs of disposal. Any impairment is recognised immediately as an expense and is not subsequently reversed. 2.6.2 Other intangible assets Intangible assets acquired separately are measured initially at cost. The cost of intangible assets acquired in a business combination is their fair value as at the date of acquisition. Following initial acquisition, intangible assets are measured at cost less any accumulated amortisation and accumulated impairment losses. Intangible assets with finite useful lives are amortised over the estimated useful lives and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortisation period and the amortisation method are reviewed at least at each financial year-end. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset is accounted for by changing the amortisation period or method, as appropriate, and are treated as changes in accounting estimates. The amortisation expense on intangible assets with finite lives is recognised in profit or loss. 193 ANNUAL REPORT 2020
