17. Derivatives and hedging
Derivative financial instruments are recognised initially, and subsequently measured, at fair value. Derivative fair values are determined from quoted prices in active markets where available. Where there is no active market for an instrument, fair value is derived from prices for the derivative’s components using appropriate pricing or valuation models.
A derivative embedded in a contract is accounted for as a stand-alone derivative if its economic characteristics are not closely related to the economic characteristics of the host contract; unless the entire contract is carried at fair value through profit or loss.
Gains and losses arising from changes in the fair value of a derivative are recognised as they arise in profit or loss unless the derivative is the hedging instrument in a qualifying hedge. The Group enters into three types of hedge relationship: hedges of changes in the fair value of a recognised asset or liability or firm commitment (fair value hedges); hedges of the variability in cash flows from a recognised asset or liability or a forecast transaction (cash flow hedges); and hedges of the net investment in a foreign operation.
Hedge relationships are formally documented at inception. The documentation includes identification of the hedged item and the hedging instrument, details the risk that is being hedged and the way in which effectiveness will be assessed at inception and during the period of the hedge. If the hedge is not highly effective in offsetting changes in fair values or cash flows attributable to the hedged risk, consistent with the documented risk management strategy, hedge accounting is discontinued.
Fair value hedge – in a fair value hedge, the gain or loss on the hedging instrument is recognised in profit or loss. The gain or loss on the hedged item attributable to the hedged risk is recognised in profit or loss and adjusts the carrying amount of the hedged item. Hedge accounting is discontinued if the hedge no longer meets the criteria for hedge accounting or if the hedging instrument expires or is sold, terminated or exercised or if hedge designation is revoked. If the hedged item is one for which the effective interest rate method is used, any cumulative adjustment is amortised to profit or loss over the life of the hedged item using a recalculated effective interest rate.
Cash flow hedge – where a derivative financial instrument is designated as a hedge of the variability in cash flows of a recognised asset or liability or a highly probable forecast transaction, the effective portion of the gain or loss on the hedging instrument is recognised directly in equity. The ineffective portion is recognised in profit or loss. When the forecast transaction results in the recognition of a financial asset or financial liability, the cumulative gain or loss is reclassified from equity in the same periods in which the asset or liability affects profit or loss. Otherwise the cumulative gain or loss is removed from equity and recognised in profit or loss at the same time as the hedged transaction. Hedge accounting is discontinued if the hedge no longer meets the criteria for hedge accounting; if the hedging instrument expires or is sold, terminated or exercised; if the forecast transaction is no longer expected to occur; or if hedge designation is revoked. On the discontinuance of hedge accounting (except where a forecast transaction is no longer expected to occur), the cumulative unrealised gain or loss recognised in equity is recognised in profit or loss when the hedged cash flow occurs or, if the forecast transaction results in the recognition of a financial asset or financial liability, in the same periods during which the asset or liability affects profit or loss. Where a forecast transaction is no longer expected to occur, the cumulative unrealised gain or loss is recognised in profit or loss immediately.
Hedge of net investment in a foreign operation – where a foreign currency liability hedges a net investment in a foreign operation, the portion of foreign exchange differences arising on translation of the liability determined to be an effective hedge is recognised directly in equity. Any ineffective portion is recognised in profit or loss.
