Measurement of derivative financial instruments

As required by the International Financial Reporting Standards, derivative financial instruments disclosed in the financial statements are measured at fair value.

As at December 31st 2014, the Group held the following types of derivatives: Cross Currency Interest Rate Swaps (CCIRS), Interest Rate Swaps (IRS), purchased European and Asian currency call options, purchased and sold currency and commodity forwards (physically settled), purchased and sold futures, as well as purchased average rate forwards. In 2014, the Group also hedged against commodity price risk using Asian call options, risk reversal strategies (purchase of Asian commodity call options and sale of put options) and purchased commodity swaps.

Currency call options were measured at fair value using the Garman-Kohlhagen model, whereas Asian commodity call and put options were measured at fair value using the Espen-Levy model. Forwards, average rate forwards, swaps, CCIRS and IRS transactions are measured at fair value using the discount method. The measurement was based on market data such as interest rates, foreign-exchange rates, basis spreads, commodity prices and volatility of commodity prices as at December 31st 2014.

Hedge accounting

The Parent applies cash-flow hedge accounting with respect to foreign exchange transactions and commodity transactions, as well as fair-value hedge accounting with respect to an advanced loan. For details, see Note 2.3.12.

33.1.  Derivative financial instruments

Positive valuation of derivatives as at the end of the period is presented in the statement of financial position as a separate item of current assets. Negative valuation of derivatives is presented in the statement of financial position as a separate item of current liabilities. Effects of valuation of open positions are taken to profit or loss for the period, or directly to equity if there is an effective portion which constitutes an effective hedge of changes in fair value of financial derivatives designated as cash flow hedges. In such a case, at the time of exercise of the derivative financial instrument and of the hedged item, the Group’s equity is decreased or increased, and the effective portion is charged to profit or loss at the place of origination of the hedged item’s costs. The non-effective portion and the fair value of transactions not designated as hedges is recognised under other items of the profit or loss of the period.
