Taking into consideration the fair value of open derivatives transactions entered into by the Group and receivables and liabilities due to settled derivatives, as at 31 December 2020 the maximum single entity share of the amount exposed to credit risk arising from these transactions amounted to 36%, or PLN 158 million (as at 31 December 2019: 15%, or PLN 49 million).
In order to reduce cash flows and at the same time to limit credit risk, the Parent Entity carries out net settlements (based on standard framework agreements entered into with its customers, regulating the trade of financial instruments, meaning ISDA or based on a formula of the Polish Bank Association). Moreover, the resulting credit risk is continuously monitored by reviewing the credit ratings and is limited by striving to diversify the portfolio while implementing hedging strategies.
Despite the concentration of credit risk associated with derivatives’ transactions, the Parent Entity has determined that, due to its cooperation solely with renowned financial institutions, as well as continuous monitoring of their ratings, it is not materially exposed to credit risk as a result of transactions concluded with them.
The following table presents the structure of ratings of the financial institutions with whom the Group had derivatives transactions, representing exposure to credit risk.
