CENTURY ALUMINUM CO 10-Q

Item 3. Quantitative and Qualitative Disclosures about Market Risk Commodity Price and Raw Material Costs Sensitivities Aluminum is an internationally traded commodity, and its price is effectively determined on the LME plus any regional premium (e.g. the Midwest premium for aluminum sold in the United States and the European Duty Paid premium for metal sold into Europe) and any product premiums. From time to time, we may manage our exposure to fluctuations in the LME price of primary aluminum and/or associated regional premiums through financial instruments designed to protect our downside price risk exposure. From time to time, we also enter into financial contracts to offset fixed price sales arrangements with certain of our customers (the "fixed for floating swaps"). We are also exposed to price risk for alumina which is one of the largest components of our cost of goods sold. Certain of the alumina we purchase is priced based on a published alumina index. As a result, our cost structure is exposed to market fluctuations and price volatility. Because we sell our products based principally on the LME price for primary aluminum, regional premiums and value-added product premiums, we are not able to directly pass on increased production costs to our customers. From time to time, we may manage our exposure to fluctuations in our alumina costs by purchasing certain of our alumina requirements under supply contracts with prices tied to the same indices as our aluminum sales contracts (the LME price of primary aluminum). Market-Based Power Price Sensitivity Market-Based Electrical Power Agreements Hawesville and Sebree have market-based electrical power agreements pursuant to which EDF and Kenergy purchase electrical power on the open market and pass it through at MISO energy pricing, plus transmission and other costs incurred by them. See Note 1 1 . Commitments and Contingencies to the consolidated financial statements included herein for additional information about these market-based power agreements. Power is supplied to Grundartangi from hydroelectric and geothermal sources under long-term power purchase agreements. These power purchase agreements, which will expire on various dates from 2026 through 2036 (subject to extension), currently primarily provide power at LME-based variable rates. At this time, the price of approximately 30% of Grundartangi's power requirements is linked to the market price for power in the Nord Pool power market. From time to time, we may manage our exposure to fluctuations in the market price of power through financial instruments designed to protect our downside risk exposure. Electrical Power Price Sensitivity Power represents one of our largest operating costs, so changes in the price and/or availability of market power could significantly impact the profitability and viability of our operations. Given our market-based power supply agreements, we have electrical power price risk for our operations, whether due to fluctuations in the price of power (whether it be the cost of energy itself, generation capacity costs, or transmission costs) available on the MISO or Nord Pool power markets or the price of natural gas. Transmission line outages, reduction in power production by power suppliers, problems with grid stability or limitations on energy import capability could also increase power prices, disrupt production through pot instability or force a curtailment of all or part of the production at these facilities. In addition, indirect factors that lead to power cost increases, such as any disruptions in supply of natural gas or coal, increasing prices for natural gas or coal, fluctuations in or extremes in weather patterns or new or more stringent environmental regulations may severely impact our financial condition, results of operations and liquidity. 40 The consumption shown in the table below reflects each operation at 100% capacity and does not reflect partial production curtailments.

Grundartangi’s labor costs, costs associated with the casthouse project, part of its maintenance costs and other local services are denominated in ISK and a portion of its anode costs are denominated in Euros and Chinese renminbi. We also have deposits denominated in ISK in Icelandic banks and our estimated payments of Icelandic income taxes and any associated refunds are denominated in ISK. Further, Vlissingen's labor costs, maintenance costs and other local services are denominated in Euros and our existing Nord Pool power price swaps described above are settled in Euros. As a result, an increase or decrease in the value of those currencies relative to the U.S. dollar would affect Grundartangi’s and Vlissingen's operating margins. We may manage our exposure by entering into foreign currency forward contracts or option contracts for forecasted transactions and projected cash flows for foreign currencies in future periods. We have entered into financial contracts to hedge the risk of fluctuations associated with the Euro under our power price swaps (the "FX swaps"). Natural Economic Hedges Any analysis of our exposure to the commodity price of aluminum should consider the impact of natural hedges provided by certain contracts that contain pricing indexed to the LME price for primary aluminum. Certain of our alumina contracts and a substantial portion of Grundartangi’s electrical power requirements are indexed to the LME price for primary aluminum and provide a natural hedge for a portion of our production. Risk Management Any metals, power, natural gas and foreign currency risk management activities are subject to the control and direction of senior management within guidelines established by Century’s Board of Directors.
