13. | Derivative Instruments
We manufacture and market our products in a number of countries throughout the world and, as a result, are exposed to changes in foreign currency exchange rates, particularly in South Africa, Australia, and the Netherlands. Costs in South Africa and Australia are primarily incurred in local currencies, while the majority of revenues are in U.S. dollars. In Europe, the majority of revenues and costs are in the local currency. This leaves us exposed to movements in the South African Rand and the Australian dollar versus the U.S. dollar. Our businesses rely on natural gas as one of the main fuel sources in our production process. Natural gas prices have historically been volatile. Natural gas prices could increase as a result of reduced domestic drilling and production activity. Drilling and production operations are subject to extensive federal, state, local and foreign laws and government regulations, which could directly curtail such activity or increase the cost of drilling, resulting in reduced levels of drilling activity and therefore increased natural gas prices. This exposes us to commodity price risk. We mitigate our exposures to currency risks and commodity price risks, through a controlled program of risk management that includes the use of derivative financial instruments. We enter into foreign exchange forward contracts to reduce the effects of fluctuating foreign currency exchange rates. We also use commodity price swap contracts and forward purchase contracts to manage forecasted energy exposure. We formally document all relationships between hedging instruments and hedged items, as well as the risk management objective and strategy for undertaking our hedge transactions. This process includes relating derivatives that are designated as cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. We also formally assess, both at the inception of the hedge and throughout its term, whether each derivative is highly effective in offsetting changes in cash flows of the hedged item. If we determine that a derivative is not highly effective as a hedge, or if a derivative ceases to be a highly effective hedge, we discontinue hedge accounting with respect to that derivative prospectively. On the date the derivative instrument is entered into, we assess whether to designate the derivative as a hedge of the variability of cash flows to be received or paid related to a forecasted transaction (cash flow hedge) or not. We recognize all derivatives in the unaudited Condensed Consolidated Balance Sheets at fair value. We have designated our natural gas commodity price swap contracts, which qualify as cash flow hedges, for hedge accounting treatment under ASC 815. We perform an analysis for effectiveness of the derivatives at the end of each quarter based on the terms of the contract and the underlying item being hedged. The effective portion of the change in the fair value of cash flow hedges is deferred in other comprehensive loss and is subsequently recognized in “Cost of goods sold” in the unaudited Condensed Consolidated Statements of Operations for commodity hedges, when the hedged item impacts earnings. Any portion of the change in fair value of derivatives designated as hedging instruments that is determined to be ineffective is recorded in “Other income (expense), net” in the unaudited Condensed Consolidated Statements of Operations. At March 31, 2017 and December 31, 2016, we recorded the fair value of the natural gas hedge of $1 million and $3 million, respectively in “Prepaid and other assets” in the unaudited Condensed Consolidated Balance Sheets, with the offset of $2 million during the three months ended March 31, 2017 of unrealized gain recognized in accumulated other comprehensive loss, with no tax impact, which is expected to be reclassified as earnings within the next nine months. See Note 3 to the unaudited condensed consolidated financial statements. The current open commodity contract hedges forecasted transactions until December 31, 2017. At March 31, 2017 and December 31, 2016, we had an equivalent of 3.8 MMBTUs (millions of British Thermal Units) and 4.8 MMBTUs, respectively, in aggregate notional volume of outstanding natural gas commodity forward contract to hedge forecasted purchases. The fair value of the natural gas commodity price contract was based on market price quotations and the use of a pricing model. The contract was considered a level 2 input in the fair value hierarchy at March 31, 2017 and December 31, 2016.
