The Group applies the simplified model of calculating the allowance for impairment of trade receivables (regardless of their maturity). The expected credit loss on trade receivables is calculated at the closest ending date of the reporting period after the moment of recognition of a receivable in the statement of financial position and is updated at every subsequent reporting period ending date. In order to estimate the expected credit loss on trade receivables, the Group’s entities apply provision matrices, made on the basis of historical levels of payment of trade receivables, which are periodically recalibrated in order to update them.
Loss allowance for expected credit losses is measured at the amount equal to expected credit losses during the whole life of the receivables. The Group adopted an assumption that the receivable risk is characterised by the number of days of delay and this parameter determines the estimated PD, i.e. the probability of a delay in payment of trade receivables by at least 90 days. For the purpose of estimating PD, 5 risk groups have been selected based on the criteria of number of days in payment, according to ranges presented below as “Important estimates and assumptions”.
Default is defined as being a failure by a customer to meet its liabilities after a period of 90 days from the due date. In order to estimate the loss allowance for expected credit losses, collateral is also taken into account by allocating expected recovery rates to the particular types of collateral.
Moreover, forward-looking information is taken into account in the applied parameters of the model for estimating expected losses, by adjusting the base coefficients of default probability. This means that if as a result of analysis of macroeconomic data, such as for example: current GDP dynamics, inflation, unemployment rate, or WIG index, the Group recognises any deterioration in them in comparison to the previous period, in the ECL calculation the looking forward factor, which corrects risk connected with any decrease in receivables recovery, is taken into account. As at 31 December 2021, or the end of the reporting period, no deterioration of macroeconomic factors was noted. Despite the growing inflation, alongside the favourable performance of among others the GDP, unemployment rate, and also forecasts of these indicators, the Parent Entity did not note any deterioration of macroeconomic factors as at the end of the reporting period on 31 December 2021.
