Separately acquired trademarks and licences are shown at historical cost.
Trademarks, licences (including software) and customer-related intangible assets acquired in a business combination are recognised at fair value at the aquisition date.
Trademarks, licences and customer-related intangible assets have a finite useful life and are carried at cost less accumulated amortisation and any accumulated impairment losses.
The company has adopted the policy of not amortising the intangible assets due to a steady increase in the market value of those assets. This policy is consistent with the treatment of intangible assets adopted by the company's parent company.
