Derivative financial instruments
The Group from time to time may enter into derivative financial instruments to hedge its exposure to market fluctuations, foreign exchange and interest rate risks arising from operational, financing and investment activities.
On initial designation of the derivative as hedging instrument, the Group formally documents the relationship between the hedging instrument(s) and hedged item(s), including the risk management objectives and strategy in undertaking the hedge transaction, together with the methods that will be used to assess the effectiveness of the hedging relationship. The Group makes an assessment, both at the inception of the hedge relationship as well as on an ongoing basis, whether the hedging instruments are expected to be "highly effective" in offsetting the changes in the fair value or cash flows of the respective hedged items during the period for which the hedge is designated, and whether the actual results of each hedge are within a range of 80-125 percent. For a cash flow hedge of a forecast transaction, the transaction should be highly probable to occur and should present an exposure to variations in cash flows that could ultimately affect reported net income.
Derivative financial instruments are recognized initially at fair value; attributable transaction costs are expensed as incurred. Subsequent to initial recognition, all derivatives are remeasured to fair value, and changes therein are accounted for as follows:
Cash flow hedges
When a derivative is designated as the hedging instrument in a hedge of the variability in cash flows attributable to a particular risk associated with a recognized asset or liability or a highly probable forecast transaction that could affect profit or loss, the effective portion of changes in the fair value of the derivative is recognized in OCI and presented in the hedging reserve in equity.
The amount recognized in OCI is removed and included in profit or loss in the same period as the hedged cash flows affect profit or loss under the same line item in the statement of profit or loss as the hedged item. Any ineffective portion of changes in the fair value of the derivative is recognized immediately in profit or loss.
When the hedged item is a non-financial asset, the amount accumulated in equity is included in the carrying amount of the asset when the asset is recognized. In other cases, the amount accumulated in equity is reclassified to profit or loss in the same period that the hedged item affects profit or loss.
If the hedging instrument no longer meets the criteria for hedge accounting, expires or is sold, terminated, exercised, or the designation is revoked, then hedge accounting is discontinued prospectively. If the forecast transaction is no longer expected to occur, then the balance in equity is reclassified to profit or loss.
Other non-trading derivatives
When a derivative financial instrument is not held for trading, and is not designated in a qualifying hedge relationship, all changes in its fair value are recognized immediately in profit or loss.
