The amortisation period and the amortisation method for an intangible asset with a
finite useful life shall be reviewed at least at each financial year-end. If the expected
useful life of the asset is different from previous estimates, the amortisation period
shall be changed accordingly. If there has been a change in the expected pattern of
consumption of the future economic benefits embodied in the asset, the amortisation
method shall be changed to reflect the changed pattern. Such changes shall be
accounted for as changes in accounting estimates in accordance with SB-FRS 8.
