(h) Intangible assets

Intangible assets acquired separately are measured on initial recognition at cost. Following initial recognition, intangible assets are carried at cost, less any accumulated amortization and accumulated impairment losses.

Software is recognized at historical cost and is amortized, on a straight-line basis, over its useful life. The useful life of software is generally between 3 and 5 years, dependent on the type of software.

Research costs are expensed when incurred. In compliance with IAS 38, development costs are capitalized if all of the following criteria are met:

• The projects are clearly defined.
• The Company is able to reliably measure expenditures incurred by each project during its development.
• The Company is able to demonstrate the technical feasibility of the project.
• The Company has the financial and technical resources available to achieve the project.
• The Company can demonstrate its intention to complete, to use or to commercialize products resulting from the project.
• The Company is able to demonstrate the existence of a market for the output of the intangible asset, or, if it is used internally, the usefulness of the intangible asset.

When capitalized, development costs are carried at cost, less any accumulated amortization and impairment losses. Amortization begins when the project is complete and available for use. It is amortized over the period of expected future benefit, which is generally between 3 and 5 years.
