52.1.1 Credit risk related to receivables from customers

The Group has receivables from two groups of customers: institutional customers and individual customers.

The Group has no significant concentrations of credit risk related to its core business. Amounts due from PSE S.A. constitute the largest item of receivables from buyers with a share of 8.06% as at 31 December 2020 and 6.69% as at 31 December 2019, respectively. The Group monitors credit risk related to its operations on an ongoing basis, in line with the Credit Risk Management Policy in TAURON Group. As a result of the analysis of credit standing of counterparties with significant credit exposure, the conclusion of trading transactions resulting in an increase in credit exposure above the allocated exposure limit generally requires the establishment of a collateral. In an environment of uncertainty and dynamic changes caused by the COVID-19 pandemic, TAURON Group’s credit risk measures focus on early identification of potential counterparties exposed to increased levels of credit risk. These measures include, among others, tightening of the rules for assessing the financial standing of counterparties, continuous monitoring of receivables, monitoring of industry information and the macroeconomic environment. The ageing of receivables from customers and information on impairment losses on receivables from customers is presented in Note 32 to these consolidated financial statements.
