Reserve for expected credit losses – financial instruments using simplified approach
Receivables mainly consist of accounts receivable, for which the Group applies the simplified method of accounting for expected credit losses. This entails making credit loss provisions for the remaining lifetime, which is expected to be less than one year for all receivables. The Group's counterparties consist mainly of actors in the public sector, where the majority of sales are made through public procurement for which credit risk is considered very low. The expected loan losses for accounts receivables are calculated using a commission matrix which is based on past events, current conditions and forecasts for future economic conditions and the time value of the money if applicable. The Group defines defaults as being considered unlikely that the counterparty will meet its obligations due to indicators such as financial difficulties and missed payments. Notwithstanding the above, default is deemed to have taken place when the payment is 90 days past due. The Group writes off a receivable when no opportunities for additional cash flows are deemed to exist.
