Merck uses derivatives solely to hedge recognized assets or liabilities and forecast transactions. Hedge accounting in accordance with IFRS is applied to some of these hedges. A distinction is made between fair value hedge accounting and cash flow hedge accounting. Designation of a hedging relationship requires a hedged item (underlying) and a hedging instrument assigned to that hedged item. At Merck, all hedges relate to existing or highly probable hedged items. Merck only uses derivatives as hedging instruments.
The hedging relationship must be effective at all times, i.e. the development of the value of the hedging instrument fully offsets changes in the value of the hedged item. In both cash flow and fair value hedges, the ineffective portion of the gain or loss on a hedging instrument is recognized in profit or loss. Merck uses the dollar offset method to measure hedge effectiveness. There are strict documentation requirements for hedge accounting. Derivatives that do not or no longer meet the documentation or effectiveness requirements for hedge accounting, or whose hedged item no longer exists, are reported as “financial assets and liabilities at fair value through profit or loss.” Changes in fair value are then recognized in profit or loss.
As a rule, the purpose of a fair value hedge is to offset the exposure to changes in the fair value of recognized hedged items (financial assets or financial liabilities) through offsetting changes in the fair value of a hedging instrument. Offsetting gains and losses on the hedging instrument resulting from changes in fair value are recognized in profit or loss, net of deferred taxes. Offsetting gains and losses on the hedged item that are attributable to the hedged risk are also recognized in profit or loss, irrespective of the item’s allocation to a measurement category.
At Merck, cash flow hedges are normally a hedge of the exposure to variability in cash flows resulting from highly probable forecast transactions in foreign currencies. In cash flow hedges, the effective portion of the gains and losses on the hedging instrument is recognized in equity until the hedged item occurs. This is also the case if the hedging instrument expires, is sold, or is terminated before the hedged transaction occurs. The ineffective portion of a cash flow hedge is always recognized in profit or loss.
