Turnover is measured at the fair value of the consideration received or receivable, excluding discounts, rebates, value added tax and other sales taxes.

Sales are recognised when an invoice is raised.

Intangible assets are initially measured at cost. After initial recognition, intangible assets are measured at cost less any accumulated amortisation and any accumulated impairment losses.

Patents and licences are being amortised evenly over their estimated useful life of ten years.

Development costs are being amortised evenly over their estimated useful life of ten years.
