72 An entity shall choose either the cost model in paragraph 74 or the revaluation model in paragraph 75 as its accounting policy. If an intangible asset is accounted for using the revaluation model, all the other assets in its class shall also be accounted for using the same model, unless there is no active market for those assets.

73 A class of intangible assets is a grouping of assets of a similar nature and use in an entity’s operations. The items within a class of intangible assets are revalued simultaneously to avoid selective revaluation of assets and the reporting of amounts in the financial statements representing a mixture of costs and values as at different dates.

Cost model

74 After initial recognition, an intangible asset shall be carried at its cost less any accumulated amortisation and any accumulated impairment losses.
