Trade receivables are recognized initially at the amount of the unconditional consideration, unless they contain significant financing components, in which case they are recognized at fair value.

The Company applies the IFRS 9 - Financial Instruments simplified approach to measuring expected credit losses whereby impairment allowances for trade receivables are measured upon initial recognition on the basis of the expected 12-month credit losses. This is primarily based on past experience of credit losses, current data on overdue receivables and credit score information. Prospective information (such as forecast economic performance indicators) is also taken into consideration if, based on past experience, such indicators show a strong correlation with actual credit losses. Typically trade receivables which are outstanding for more than 90 days are fully provisioned.
