| (f) | Other intangible assets |
Other intangible assets that are acquired by the Group are stated in the balance sheets at cost less accumulated amortization (where the estimated useful life is finite) and impairment losses (see note 2(i)). Amortization of intangible assets with finite useful lives is recorded in other operating expenses on a straight-line basis over the assets’ estimated useful lives, from the date they are available for use. Both the period and method of amortization are reviewed annually.
Intangible assets are not amortized where their useful lives are assessed to be indefinite. The useful life of an intangible asset that is not being amortized is reviewed annually to determine whether events and circumstances continue to support the indefinite useful life assessment for that asset. Otherwise, the change in useful life assessment from indefinite to finite is accounted for prospectively from the date of change and in accordance with the policy for amortization of intangible assets with finite lives as set out above.
