Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivative Financial Instruments and Related Hedging Programs | Derivative Financial Instruments and Related Hedging Programs Overview. In conducting our business, we enter into derivative transactions, including forward contracts and options, to limit our economic (i.e. cash) exposure resulting from: (i) metal price risk related to our sale of fabricated aluminum products and the purchase of metal used as raw material for our fabrication operations; (ii) energy price risk relating to fluctuating prices of natural gas and electricity used in our production processes; and (iii) foreign currency requirements with respect to our foreign subsidiaries and cash commitments for equipment purchases denominated in foreign currency. Our derivative activities are overseen by a hedging committee ("Hedging Committee"), which is composed of our chief executive officer, chief operating officer, chief financial officer, chief accounting officer, treasurer and vice president of commodity risk management and other officers and employees selected by the chief executive officer. The Hedging Committee meets regularly to review derivative positions and strategy and reports to our Board of Directors on the scope of its activities. Hedges of Operational Risks Designated Foreign Currency Cash Flow Hedges. We are exposed to foreign currency exchange risk related to firm-price agreements for equipment purchases from foreign manufacturers. Such agreements require that we make payments in foreign currency to the vendor over time based on milestone achievements. We use foreign currency forward contracts in order to mitigate the exposure to currency exchange rate fluctuations related to these purchases. The timing and amounts of the forward contract settlements are designed to line up with the timing and amounts of scheduled payments to the foreign equipment manufacturers and are therefore expected to be highly effective hedges. During 2015, we entered into forward contracts designated as cash flow hedges to purchase euros. As of December 31, 2015, we had open contracts with maturity dates between one month and 12 months related to these foreign currency forward contracts. The notional amounts of these foreign currency forward contracts totaled 4.7 million euros at December 31, 2015 with an average contract exchange rate of 1.15 euro to US dollar. The effective portion of the fair value on these instruments is recorded within Other comprehensive (loss) income and is reclassified into the Statements of Consolidated (Loss) Income on the same line item and the same period in which the underlying equipment is depreciated. We had no such reclassifications into Net (loss) income during 2015 and anticipate no such reclassifications for the next 12 months. For 2015, we recorded an unrealized loss of $0.3 million on the effective portions of our designated foreign currency cash flow hedges, resulting in an ending balance in Accumulated other comprehensive loss related to the cash flow hedges of $0.3 million at December 31, 2015. We incurred no ineffectiveness on these hedges during 2015. There were no forward contracts designated as cash flow hedges as of December 31, 2014. Non-Designated Hedges of Operational Risks. Our pricing of fabricated aluminum products is generally intended to lock in a conversion margin (representing the value added from the fabrication process(es)) and to pass through metal price fluctuations to our customers. For some of our higher value added products sold on a spot basis, the pass through of metal price movements can sometimes lag by as much as several months, with a favorable impact to us when metal prices decline and an adverse impact to us when metal prices increase. Additionally, in certain instances, we enter into firm-price arrangements with our customers for stipulated volumes to be delivered in the future. Because we generally purchase primary and secondary aluminum on a floating price basis, the lag in passing through metal price movements to customers on some of our higher value added products sold on a spot basis and the volume that we have committed to sell to our customers under a firm-price arrangement create metal price risk for us. We use third-party hedging instruments to limit exposure to metal price risk related to the metal pass through lag on some of our products and firm-price customer sales contracts. See Note 11 for additional information regarding our material derivative positions relating to hedges of operational risk and their respective fair values. A majority of our derivative contracts relating to hedges of operational risks contain liquidity based thresholds that could require us to provide additional collateral in the event our liquidity were to fall below specified levels. To minimize the exposure to additional collateral requirements related to our liability hedge positions, we allocate hedging transactions among our counterparties, use options as part of our hedging activities, or both. The aggregate fair value of our derivative instruments that were in a net liability position at December 31, 2015 was $14.6 million, and we had no collateral posted as of that date. We regularly review the creditworthiness of our derivative counterparties and do not expect to incur significant loss from the failure of any counterparties to perform under any agreements. Hedges Relating to the Convertible Notes As described in Note 3, in 2010 we issued $175.0 million principal amount of Convertible Notes due on April 1, 2015, which could only be settled in cash, and we purchased Option Assets that settled at the same time as the Convertible Notes to hedge their cash conversion feature. We accounted for the Option Assets as derivative instruments (assets) and the Bifurcated Conversion Feature of the Convertible Notes as a derivative liability, separate from the Convertible Notes. Upon settlement, the Option Assets' proceeds of $94.9 million equaled and offset the cash conversion premium, represented by the Bifurcated Conversion Feature, that we paid on the Convertible Notes. See Note 11 for additional information regarding the fair values of the Bifurcated Conversion Feature and the Option Assets. Realized and Unrealized Gains and Losses. Realized and unrealized (losses) gains associated with all derivative contracts consisted of the following for each period presented (in millions of dollars):
