An aggregate assessment of the impairment is carried out and the impairment losses due to impairment are estimated for receivables from policyholders which do not contain a significant financing component.
Receivables are grouped by similar credit risk characteristics. For receivables before maturity, the value of the receivable that is likely to become due is determined based on a historical analysis of the percentage of the ratio of receivables that are not paid before maturity. The amount of write-off for expected credit losses is determined on the basis of the uncollectibility ratio for matured receivables with the shortest past due period.
For matured receivables, an age structure is prepared, depending on the past due period. For this group, the value of the allowance for expected credit losses is calculated in separate ranges of past due periods, based on the uncollectibility ratios determined through historical analysis.
