Derivatives

The Group measures derivatives at fair value using valuation models for financial instruments based on publicly available exchange rates, interest rates, discount curves in particular currencies (applicable also for commodities which prices are denominated in these currencies) derived from active markets. The fair value of derivatives is determined based on discounted future cash flows from transactions, calculated based on the difference between the forward rate and transaction price. Forward exchange rates are not modelled as separate risk factor, but are derived from the spot rate and appropriate forward interest rate for foreign currencies in relation to PLN.

In the category of financial assets at fair value through profit or loss, the Group presents derivatives related to greenhouse gases emission rights – currency and commodity forwards and IRS hedging transactions changing variable interest rate in PLN to fixed interest rate in PLN (Level 2).

In addition, the Group presents CCIRS derivative that hedges foreign exchange rate and interest rate (Level 2).
