100 The residual value of an intangible asset with a finite useful life shall be assumed to be zero unless:
(a) there is a commitment by a third party to purchase the asset at the end of its useful life; or
(b) there is an active market (as defined in AASB 13) for the asset and:
(i) residual value can be determined by reference to that market; and
(ii) it is probable that such a market will exist at the end of the asset’s useful life.
101 The depreciable amount of an asset with a finite useful life is determined after deducting its residual value. A residual value other than zero implies that an entity expects to dispose of the intangible asset before the end of its economic life.
102 An estimate of an asset’s residual value is based on the amount recoverable from disposal using prices prevailing at the date of the estimate for the sale of a similar asset that has reached the end of its useful life and has operated under conditions similar to those in which the asset will be used. The residual value is reviewed at least at each financial year-end. A change in the asset’s residual value is accounted for as a change in an accounting estimate in accordance with AASB 108 Accounting Policies, Changes in Accounting Estimates and Errors.
103 The residual value of an intangible asset may increase to an amount equal to or greater than the asset’s carrying amount. If it does, the asset’s amortisation charge is zero unless and until its residual value subsequently decreases to an amount below the asset’s carrying amount.

Review of amortisation period and amortisation method

104 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 AASB 108.
105 During the life of an intangible asset, it may become apparent that the estimate of its useful life is inappropriate. For example, the recognition of an impairment loss may indicate that the amortisation period needs to be changed.
106 Over time, the pattern of future economic benefits expected to flow to an entity from an intangible asset may change. For example, it may become apparent that a diminishing balance method of amortisation is appropriate rather than a straight-line method. Another example is if use of the rights represented by a licence is deferred pending action on other components of the business plan. In this case, economic benefits that flow from the asset may not be received until later periods.
