Assumptions and estimates

The preparation of the IFRS consolidated financial statements requires the use of assumptions and estimates for certain line items that affect recognition and measurement in the consolidated statement of financial position and consolidated income statement. The actual amounts realised may differ from estimates. Assumptions and estimates are applied in particular:

  • in assessing the need for and the amount of impairment losses on intangible assets, property, plant and equipment, and inventories
  • in determining the useful life of non-current assets
  • in classifying and measuring leases and in determining the lease terms
  • in recognising and measuring defined benefit pension obligations and other provisions
  • in recognising and measuring current and deferred taxes
  • in recognising and measuring assets acquired and liabilities assumed in connection with business combinations, and
  • in evaluating the stage of completion of contracts where the revenue is recognised over a period of time.

The impact of a change to an estimate is recognised prospectively when it becomes known and assumptions are adjusted accordingly.
