6. Intangible assets and goodwill
Intangible assets acquired by the Group are stated at cost less accumulated amortisation and impairment losses. Amortisation is charged to profit or loss over the assets’ estimated economic lives using methods that best reflect the pattern of economic benefits and is included in Depreciation and amortisation. These estimated useful economic lives are:
|
Computer software |
3 to 12 years |
|
Other acquired intangibles |
5 to 10 years |
Expenditure on internally generated goodwill and brands is written-off as incurred. Direct costs relating to the development of internal-use computer software are capitalised once technical feasibility and economic viability have been established. These costs include payroll, the costs of materials and services, and directly attributable overheads. Capitalisation of costs ceases when the software is capable of operating as intended. During and after development, accumulated costs are reviewed for impairment against the benefits that the software is expected to generate. Costs incurred prior to the establishment of technical feasibility and economic viability are expensed as incurred as are all training costs and general overheads. The costs of licences to use computer software that are expected to generate economic benefits beyond one year are also capitalised.
Intangible assets include goodwill arising on the acquisition of subsidiaries and joint ventures. Goodwill on the acquisition of a subsidiary is the excess of the fair value of the consideration transferred, the fair value of any existing interest in the subsidiary and the amount of any non-controlling interest measured either at fair value or at its share of the subsidiary’s net assets over the Group’s interest in the net fair value of the subsidiary’s identifiable assets, liabilities and contingent liabilities. Goodwill arises on the acquisition of a joint venture when the cost of investment exceeds the Group’s share of the net fair value of the joint venture’s identifiable assets and liabilities. Goodwill is measured at initial cost less any subsequent impairment losses. Goodwill arising on the acquisition of associates is included within their carrying amounts. The gain or loss on the disposal of a subsidiary, associate or joint venture includes the carrying value of any related goodwill.
