7.3.1.3 Credit risk related to derivative transactions

Transactions in financial derivatives are executed with most reputable banks with high credit ratings. The Group has also concluded either Framework Agreements or ISDA Agreements with each of their relationship banks, stipulating detailed terms of service and limits of maximum exposure arising from the fair value of derivatives. The Group believes that all the measures described above protect it against any material credit-risk-related losses. 

The relationship banks’ credit ratings are presented in Note 7.3.1.1.
