Derivatives, which basis are non-financial assets, included in IFRS 9 Financial Instruments, involve futures (exchange market) and forward transactions (OTC). Exchange markets apply appropriate mechanisms to protect, in the form of initial and variation margin deposits. Under variation margin deposits, the Company provides and receives cash arising from changes in the measurement of the underlying instruments on an ongoing basis, which means that as at the end the reporting period, credit risk does not occur in relation to futures transactions.
In the case of OTC instruments there is a credit risk related to the possibility of insolvency of the other party to the agreement. Therefore, commercial transactions of significant value are preceded by the assessment of the credit standing counterparty, including the economic and financial analysis of the entity. On the basis of the assessment, the counterparty is granted a credit limit, which is a limit of the maximum credit exposure. Execution of trade transactions resulting in an increase in credit exposure above the allocated exposure limit generally requires the establishment of collateral in accordance with the Credit Risk Management Policy in the TAURON Group.
