Recognition of an Expense
68 Expenditure on an intangible item shall be recognised as an expense when it is incurred unless:
(a) it forms part of the cost of an intangible asset that meets the recognition criteria (see paragraphs 18-67); or
(b) the item is acquired in a business combination and cannot be recognised as an intangible asset. If this is the case, this expenditure (included in the cost of the business combination) shall form part of the amount attributed to goodwill at the acquisition date (see IFRS 3 Business Combinations).
69 In some cases, expenditure is incurred to provide future economic benefits to an entity, but no intangible asset or other asset is acquired or created that can be recognised. In these cases, the expenditure is recognised as an expense when it is incurred. For example, except when it forms part of the cost of a business combination, expenditure on research is recognised as an expense when it is incurred (see paragraph 54). Other examples of expenditure that is recognised as an expense when it is incurred include:
(a) expenditure on start-up activities (ie start-up costs), unless this expenditure is included in the cost of an item of property, plant and equipment in accordance with IAS 16 Property, Plant and Equipment. Start-up costs may consist of establishment costs such as legal and secretarial costs incurred in establishing a legal entity, expenditure to open a new facility or business (ie pre-opening costs) or expenditures for starting new operations or launching new products or processes (ie pre-operating costs).
(b) expenditure on training activities.
(c) expenditure on advertising and promotional activities.
(d) expenditure on relocating or reorganising part or all of an entity.

70 Paragraph 68 does not preclude recognising a prepayment as an asset when payment for the delivery of goods or services has been made in advance of the delivery of goods or the rendering of services.
Past Expenses not to be Recognised as an Asset
71 Expenditure on an intangible item that was initially recognised as an expense shall not be recognised as part of the cost of an intangible asset at a later date.
Measurement after Recognition
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.
Revaluation Model
75 After initial recognition, an intangible asset shall be carried at a revalued amount, being its fair value at the date of the revaluation less any subsequent accumulated amortisation and any subsequent accumulated impairment losses. For the purpose of revaluations under this Standard, fair value shall be determined by reference to an active market. Revaluations shall be made with such regularity that at the balance sheet date the carrying amount of the asset does not differ materially from its fair value.
76 The revaluation model does not allow:
(a) the revaluation of intangible assets that have not previously been recognised as assets; or
(b) the initial recognition of intangible assets at amounts other than cost.

77 The revaluation model is applied after an asset has been initially recognised at cost. However, if only part of the cost of an intangible asset is recognised as an asset because the asset did not meet the criteria for recognition until part of the way through the process (see paragraph 65), the revaluation model may be applied to the whole of that asset. Also, the revaluation model may be applied to an intangible asset that was received by way of a government grant and recognised at a nominal amount (see paragraph 44).
78 It is uncommon for an active market with the characteristics described in paragraph 8 to exist for an intangible asset, although this may happen. For example, in some jurisdictions, an active market may exist for freely transferable taxi licences, fishing licences or production quotas. However, an active market cannot exist for brands, newspaper mastheads, music and film publishing rights, patents or trademarks, because each such asset is unique. Also, although intangible assets are bought and sold, contracts are negotiated between individual buyers and sellers, and transactions are relatively infrequent. For these reasons, the price paid for one asset may not provide sufficient evidence of the fair value of another. Moreover, prices are often not available to the public.

79 The frequency of revaluations depends on the volatility of the fair values of the intangible assets being revalued. If the fair value of a revalued asset differs materially from its carrying amount, a further revaluation is necessary. Some intangible assets may experience significant and volatile movements in fair value, thus necessitating annual revaluation. Such frequent revaluations are unnecessary for intangible assets with only insignificant movements in fair value.
80 If an intangible asset is revalued, any accumulated amortisation at the date of the revaluation is either:
(a) restated proportionately with the change in the gross carrying amount of the asset so that the carrying amount of the asset after revaluation equals its revalued amount; or
(b) eliminated against the gross carrying amount of the asset and the net amount restated to the revalued amount of the asset.
81 If an intangible asset in a class of revalued intangible assets cannot be revalued because there is no active market for this asset, the asset shall be carried at its cost less any accumulated amortisation and impairment losses.

82 If the fair value of a revalued intangible asset can no longer be determined by reference to an active market, the carrying amount of the asset shall be its revalued amount at the date of the last revaluation by reference to the active market less any subsequent accumulated amortisation and any subsequent accumulated impairment losses.
83 The fact that an active market no longer exists for a revalued intangible asset may indicate that the asset may be impaired and that it needs to be tested in accordance with IAS 36 Impairment of Assets.
84 If the fair value of the asset can be determined by reference to an active market at a subsequent measurement date, the revaluation model is applied from that date.
85 If an intangible asset's carrying amount is increased as a result of a revaluation, the increase shall be credited directly to equity under the heading of revaluation surplus. However, the increase shall be recognised in profit or loss to the extent that it reverses a revaluation decrease of the same asset previously recognised in profit or loss.

86 If an intangible asset's carrying amount is decreased as a result of a revaluation, the decrease shall be recognised in profit or loss. However, the decrease shall be debited directly to equity under the heading of revaluation surplus to the extent of any credit balance in the revaluation surplus in respect of that asset.
87 The cumulative revaluation surplus included in equity may be transferred directly to retained earnings when the surplus is realised. The whole surplus may be realised on the retirement or disposal of the asset. However, some of the surplus may be realised as the asset is used by the entity; in such a case, the amount of the surplus realised is the difference between amortisation based on the revalued carrying amount of the asset and amortisation that would have been recognised based on the asset's historical cost. The transfer from revaluation surplus to retained earnings is not made through the income statement.
Useful Life

88 An entity shall assess whether the useful life of an intangible asset is finite or indefinite and, if finite, the length of, or number of production or similar units constituting, that useful life. An intangible asset shall be regarded by the entity as having an indefinite useful life when, based on an analysis of all of the relevant factors, there is no foreseeable limit to the period over which the asset is expected to generate net cash inflows for the entity.
89 The accounting for an intangible asset is based on its useful life. An intangible asset with a finite useful life is amortised (see paragraphs 97-106), and an intangible asset with an indefinite useful life is not (see paragraphs 107-110). The Illustrative Examples accompanying this Standard illustrate the determination of useful life for different intangible assets, and the subsequent accounting for those assets based on the useful life determinations.

90 Many factors are considered in determining the useful life of an intangible asset, including:
(a) the expected usage of the asset by the entity and whether the asset could be managed efficiently by another management team;
(b) typical product life cycles for the asset and public information on estimates of useful lives of similar assets that are used in a similar way;
(c) technical, technological, commercial or other types of obsolescence;
(d) the stability of the industry in which the asset operates and changes in the market demand for the products or services output from the asset;
(e) expected actions by competitors or potential competitors;
(f) the level of maintenance expenditure required to obtain the expected future economic benefits from the asset and the entity's ability and intention to reach such a level;
(g) the period of control over the asset and legal or similar limits on the use of the asset, such as the expiry dates of related leases; and
(h) whether the useful life of the asset is dependent on the useful life of other assets of the entity.

91 The term 'indefinite' does not mean 'infinite'. The useful life of an intangible asset reflects only that level of future maintenance expenditure required to maintain the asset at its standard of performance assessed at the time of estimating the asset's useful life, and the entity's ability and intention to reach such a level. A conclusion that the useful life of an intangible asset is indefinite should not depend on planned future expenditure in excess of that required to maintain the asset at that standard of performance.
92 Given the history of rapid changes in technology, computer software and many other intangible assets are susceptible to technological obsolescence. Therefore, it is likely that their useful life is short.
93 The useful life of an intangible asset may be very long or even indefinite. Uncertainty justifies estimating the useful life of an intangible asset on a prudent basis, but it does not justify choosing a life that is unrealistically short.
