Recognition and measurement

Internally generated intangible assets
Research costs are expensed as incurred.

An intangible asset arising from development expenditure on an internal project is recognised only when the Group can demonstrate the following:

  • The technical feasibility of completing the intangible asset so that it will be available for use or sale.
  • Its intention to complete and its ability to use or sell the asset.
  • How the asset will generate future economic benefits.
  • The availability of resources to complete the development of the asset.
  • The ability to measure reliably the expenditure attributable to the intangible asset during its development.

Following the initial recognition of development expenditure, the asset is carried at cost less any accumulated amortisation. Any expenditure capitalised is amortised over the period of expected benefits from the related project. The carrying value of an intangible asset arising from development expenditure is tested for impairment annually when the asset is not yet available for use or more frequently when an indication of impairment arises during the reporting period.

Software assets
Directly attributable costs associated with the development of business software for internal use are recorded as software assets if the development expenditure satisfies the criteria for capitalisation as outlined above. Costs included in software assets developed for internal use are:

  • External direct costs of materials, contract labour and services consumed
  • Payroll and payroll-related costs for employees (including contractors) directly associated with the development project.

Costs that are not directly attributable are expensed as incurred. The Group does not consider that it has any qualifying assets and therefore does not currently capitalise any borrowing costs.

Acquired intangible assets
Intangible assets acquired through separate acquisition are recorded at cost.

Amortisation
Intangible assets are amortised on a straight-line basis over their estimated useful lives. The estimated useful lives of identifiable intangible assets are as follows:

Identifiable intangible asset type

Useful lives

Software assets

3-8 years

Telecommunications licenses

Term of license

Amortisation methods, useful lives and residual values are reviewed at each reporting date and adjusted, if appropriate. Amortisation of intangible assets does not commence until the assets are installed and ready for use, as intended by the Group.

Assets in the course of construction
The carrying amount of intangible assets includes expenditure recognised on software assets which are in the course of construction. As these assets have not been installed and are not ready for use, no amortisation is charged on these assets. Total software assets in the course of construction are $186 million (2018: $177 million).

Key estimates and judgements:

Determination of useful lives of intangible assets
The estimations of useful lives, residual value and amortisation methods require significant judgement and are reviewed at each reporting date. If they require modification, the amortisation expense is accounted for prospectively from the date of reassessment until the end of the revised useful life (for both the current and future years). Such revisions are generally required when there are changes in economic circumstances, business plans and strategies, expected level of usage and future technological developments, impacting specific assets or groups of assets. It is possible that future results of operations could be materially affected by changes in these estimates.
