| Overview

We produce primary aluminum. Aluminum is an internationally traded commodity, and its price is effectively determined on the London Metal Exchange (the “LME”). Our primary aluminum facilities produce standard grade and value-added primary aluminum products. Our current primary aluminum rated production capacity is 785,000 metric tons per year (“mtpy”), of which approximately 170,000 mtpy remained curtailed as of December 31, 2011. We restarted approximately 49,000 mtpy of curtailed capacity at our Hawesville facility during 2011. We produced approximately 602,000 metric tons of primary aluminum in 2011.
Our primary aluminum capacity includes our facility in Grundartangi, Iceland (“Grundartangi”) with rated capacity of 260,000 mtpy; our facility in Hawesville, Kentucky (“Hawesville”) with rated capacity of 244,000 mtpy; a 49.7% interest in a facility in Mt. Holly, South Carolina (“Mt. Holly”) that provides us with rated capacity of 111,000 mtpy; and our facility in Ravenswood, West Virginia (“Ravenswood”), currently curtailed, with rated capacity of 170,000 mtpy. We are constructing a primary aluminum facility in Helguvik, Iceland (the “Helguvik project”) which is currently contemplated to have a rated capacity of up to 360,000 mtpy. In addition to our primary aluminum assets, we have a 40% stake in Baise Haohai Carbon Co., Ltd. (“BHH”), a carbon anode and cathode facility located in China. The BHH facility has an annual anode production capacity of up to 180,000 mtpy and an annual graphitization capacity of up to 20,000 mtpy and supplies a portion of the anodes used in our Grundartangi facility.

In light of its high relative operating cost structure, as of December 31, 2011, all operations at Ravenswood remained curtailed. We restarted the curtailed potline at our Hawesville facility in 2011. With the full restart of the curtailed potline at Hawesville, our annualized operating rated production capacity of primary aluminum increased to approximately 615,000 mtpy.
We have continued investing in the Helguvik project. During 2011, project activity and spending remained at modest levels. We plan to restart major construction activity if we are able to successfully resolve of ongoing discussions with the contracted power suppliers for the project. See “Electrical Power Supply Agreements.”
Primary Aluminum Facilities:

Facility | Location | Operational | Rated Capacity (mtpy) (4) | Ownership Percentage
Grundartangi | Grundartangi, Iceland | 1998 | 260,000 | 100%
Hawesville (1) | Hawesville, Kentucky, USA | 1970 | 244,000 | 100%

(1) | As of December 31, 2011, with the restart of the curtailed potline, the Hawesville facility is fully operational.
(2) | In February 2009, we curtailed all operations at the Ravenswood facility. We may in the future restart the curtailed operations upon the realization of several objectives, including a new power agreement which would provide for flexibility in Ravenswood’s cost structure under adverse industry conditions as well as a new labor agreement.
(3) | Alcoa holds the remaining 50.3% ownership interest and is the operator. Century’s share of Mt. Holly’s capacity is approximately 111,000 mtpy.
(4) | The rated capacity refers to the rated capacity of the technology used in the construction of the facility. The actual production capacity of a facility may significantly exceed the rated capacity through production efficiencies, increased amperage and other similar measures.

Joint Venture Facility:

Facility | Location | Type | Capacity | Ownership Percentage
Baise Haohai Carbon Co., Ltd (1) | Guangxi Zhuang, China | Carbon anode, cathode and graphitized products | 180,000 mtpy anode; 20,000 mtpy cathode/graphitized products | 40%

(1) | Guangxi Qiangqiang Carbon Co., Ltd. holds the remaining 60% ownership interest and is the operator of this facility.

Our current long-term strategic objectives are to: (a) optimize our existing assets by managing costs and improving safety, productivity and efficiency; (b) expand our primary aluminum business by constructing, investing in or acquiring additional capacity that offers favorable returns; and (c) pursue upstream opportunities in bauxite mining, alumina refining and the production of other key raw materials. The following table shows our primary aluminum shipment volumes since 2006.

Recent Developments
Information on our recent developments is available in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included herein.
Competition
The market for primary aluminum is global, and demand for aluminum varies widely from region to region. We compete with U.S. and international companies in the aluminum industry primarily in the areas of price, quality and service. In addition, aluminum competes with materials such as steel, copper, carbon fiber, composites, plastic and glass, each of which may be substituted for aluminum in certain applications.
Our Hawesville plant is located adjacent to its largest customer. This location allows Hawesville to deliver a portion of its production in molten form, at a cost savings to both parties, providing a competitive advantage over other potential suppliers. We believe that Hawesville also has a competitive advantage in that it currently is the largest producer of high purity aluminum in North America.
Customer Base
In 2011, we derived approximately 80% of our consolidated sales from our three major customers: Glencore International (together with its subsidiaries, “Glencore”), Southwire Company (“Southwire”), and BHP Billiton. Additional information about the revenues and percentage of sales to these major customers is available in Note 20 Business Segments of the consolidated financial statements included herein. We currently have long-term primary aluminum sales or tolling contracts with each of these customers. More information about these contracts is available under “Forward Physical Delivery Agreements” in Note 16 Forward delivery contracts and financial instruments of the consolidated financial statements included herein.

Financial Information about Segments and Geographic Areas
We operate in one reportable segment, primary aluminum. Additional information about our primary aluminum segment and certain geographic information is available in Note 20 Business Segments to the consolidated financial statements included herein. For a description of certain risks attendant to our operations, see Item 1A, “Risk Factors.”
Energy, Key Supplies and Raw Materials
We consume the following key supplies and raw materials in the primary aluminum reduction process:

| ● | electricity | ● | carbon anodes | ● | liquid pitch
| ● | alumina | ● | cathode blocks | ● | calcined petroleum coke
| ● | aluminum fluoride | ● | natural gas | ● | silicon carbide

Electrical power, alumina, carbon anodes and labor are the principal components of cost of goods sold. These components together represented over 80% of our 2011 cost of goods sold. We have long-term contracts to attempt to ensure the future availability of many of our cost components. For a description of certain risks attendant to our raw material supplies and labor, see Item 1A, “Risk Factors.”
Long-term Supply Contracts
Alumina Supply Agreements
A summary of our alumina supply agreements is provided below. Grundartangi does not have long-term alumina supply agreements because this facility primarily tolls alumina provided by BHP Billiton and Glencore into primary aluminum.
In 2011, 10,500 metric tons of primary aluminum was produced at Grundartangi outside of such toll agreements, using alumina purchased on a spot basis.

Facility | Supplier | Term | Pricing
Mt. Holly | Trafigura AG | Through December 31, 2013 | Variable, LME-based
Hawesville | Glencore | Through December 31, 2014 | Variable, LME-based

We use significant amounts of electricity in the aluminum production process. A summary of our long-term power supply agreements is provided below.

Facility | Supplier | Term | Pricing
Ravenswood (1) | Appalachian Power Company | Through June 30, 2012 | Based on published tariff, with provisions for pricing based on the LME price for primary aluminum
Mt. Holly (2) | South Carolina Public Service Authority (“Santee Cooper”) | Through December 31, 2015 | Fixed price, with fuel cost adjustment clause
Hawesville (3) | Big Rivers Energy Corporation (“Big Rivers”) | Through December 31, 2023 | Cost-based
Grundartangi (4) | Landsvirkjun | Through 2019 - 2036 | Variable rate based on the LME price for primary aluminum
Orkuveita Reykjavíkur (“OR”)
HS Orka hf (“HS”)
Helguvik (4)(5) | OR | Approximately 25 years from the dates of each phase of power delivery under the respective power agreements | Variable rate based on the LME price for primary aluminum
| HS

(1) | All operations at the Ravenswood facility are presently curtailed. Appalachian Power supplies all of Ravenswood’s power requirements. Effective July 2006, the Public Service Commission of the State of West Virginia (the “PSC”) approved a special rate mechanism in connection with an increase in the applicable tariff rates. Under the special rate mechanism, Ravenswood may be excused from or may defer the payment of the increase in the tariff rate if aluminum prices as quoted on the LME fall below pre-determined levels. In June 2011, the PSC extended the special rate mechanism through June 2012.
(2) | In 2010, Santee Cooper amended the Mt. Holly power contract to provide power through 2015 priced at rates fixed under currently published schedules, subject to adjustments to cover Santee Cooper’s fuel costs with early termination provisions to allow Mt. Holly to terminate the power contract early, in whole or in part, without penalty, if the LME falls below certain negotiated levels.
(3) | Century Aluminum of Kentucky, our wholly owned subsidiary (“CAKY”) entered into an arrangement (the “Big Rivers Agreement”) toprovide power for Hawesville’s full production capacity requirements (approximately 482 megawatts (“MW”)) with pricing based on the provider’s cost of production. The Big Rivers Agreement is take-or-pay for Hawesville’s energy requirements at full production. Under the terms of the Big Rivers agreement, any power not consumed by Hawesville will be made available for sale and we will receive credits for actual power sales up to our cost for that power.
(4) | The first stage of power under the Helguvikpower supply agreement with OR (approximately 47.5MW) became available in the fourth quarter of 2011. This power is currently being utilized at Grundartangi.
(5) | HS and OR have alleged that certain conditions for the delivery of power under the Helguvik power supply agreements have not yet been satisfied. We are in discussions with HS and OR with respect to the satisfaction of these conditions. See “—Primary Aluminum Facilities — Helguvik project — Power Supply Agreements” and Item 1A, “Risk Factors — If we are unable to procure a reliable source of power the Helguvik project may not be feasible.”

Labor Agreements
Our labor costs at Ravenswood and Hawesville are subject to the terms of labor contracts with the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union (“USWA”) which generally have provisions for annual fixed increases in hourly wages and benefits adjustments. The five labor unions represented at Grundartangi operate under a labor contract that establishes wages and work rules for covered employees. The employees at Mt. Holly are employed by Alcoa and are not unionized. A summary of key labor agreements is provided below.

Facility | Organization | Term
Hawesville | USWA | Through March 31, 2015
Ravenswood (1) | USWA | Expired August 31, 2010
Grundartangi (2) | Icelandic labor unions | Through December 31, 2014

(1) | We are in discussions with the USWA regarding a new labor contract, but are unable to predict the outcome of such discussions at this time. See Item 1A, “Risk Factors — Union disputes could raise our production costs or impair our production operations.”
(2) | In April 2010, Nordural Grundartangi ehf entered into a new labor agreement with the five labor unions representing approximately 84% of Grundartangi’s work force. The wage terms of the labor agreement expired in January 2011. In September 2011, we reached an agreement on revised wage terms under our existing labor agreement with these labor unions. The labor agreement in its entirety expires on December 31, 2014

Pricing
Our operating results are highly sensitive to changes in the price of primary aluminum, electrical power, raw materials and supplies used in production. As a result, we try to mitigate the effects of fluctuations in primary aluminum, electrical power, raw material and supply prices using various fixed-price commitments and financial instruments. We purchase alumina for our U.S. facilities and electrical power at Grundartangi at prices indexed to the price of primary aluminum; this mechanism provides a “natural hedge” in the pricing of some of our largest production costs. In addition, in recent years, we have purchased primary aluminum put option contracts to protect our downside price risk exposure for a significant portion of our domestic production.
Generally, we price our products at an indexed or “market” price, in which the customer pays an agreed-upon premium over the LME price or other market indices.
Grundartangi derives most of its revenues from tolling arrangements whereby it converts alumina provided by its customers into primary aluminum for a fee based on the LME price for primary aluminum. Grundartangi's revenues are subject to market price risk associated with the LME price for primary aluminum; however, because Grundartangi tolls alumina for its customers, it is not exposed to fluctuations in the price of alumina for its tolling production. Grundartangi’s tolling revenues include a premium based on the European Union (“EU”) import duty for primary aluminum. Any decreases in the EU import duty could have a negative impact on Grundartangi’s revenues.
Primary Aluminum Facilities
Grundartangi
The Grundartangi facility located in Grundartangi, Iceland, is owned and operated by our subsidiary, Nordural Grundartangi ehf. Grundartangi is our most modern and lowest cost facility. Operations began in 1998 and production capacity has expanded to its current annual rated production capacity of 260,000 mtpy. In 2011, Grundartangi produced almost 278,000 metric tons of primary aluminum, seven percent above its rated production capacity.
- 7 -

Table of Contents
Grundartangi operates under various long-term agreements with the Government of Iceland, local municipalities, and Faxafloahafnir sf (which operates the harbor at Grundartangi and is jointly owned by several municipalities). These agreements include: (a) an investment agreement which establishes Grundartangi's tax status and the Government's obligations to grant certain permits; (b) a reduction plant site agreement by which Grundartangi leases the property; and (c) a harbor agreement by which Grundartangi is granted access to the port at Grundartangi through 2020, subject to renewal at its option.
Tolling Agreements. Grundartangi has long-term tolling agreements for most of its production capacity with BHP Billiton and Glencore. The tolling counterparties provide alumina and receive primary aluminum in return for tolling fees that are based on the LME price of primary aluminum. See Note 16 Forward delivery contracts and financial instruments in the consolidated financial statements included herein for more information about these agreements.
Direct Sales. In 2011, Grundartangi produced approximately 10,500 metric tons of primary aluminum outside of the tolling agreements, using alumina purchased on a spot basis.
Power. Grundartangi purchases power from Landsvirkjun, HS and OR under various long-term contracts due to expire between 2019 and 2036. The power delivered to Grundartangi is priced at rates based on the LME price for primary aluminum and is produced from hydroelectric and geothermal sources.
Employees. Our employees at Grundartangi are represented by five labor unions that operate under a labor contract through December 31, 2014. See “Long-term Supply Contracts - Labor Agreements” above.
Hawesville
Hawesville is owned and operated by Century Aluminum of Kentucky, our wholly owned subsidiary. Hawesville is located adjacent to the Ohio River near Hawesville, Kentucky and began operations in 1970. Hawesville has five reduction potlines with an annual rated production capacity of 244,000 metric tons.
Four of Hawesville's potlines are specially configured and operated to produce high purity primary aluminum and have an annual rated production capacity of approximately 195,000 metric tons, making it the largest producer of high purity primary aluminum in North America. The average purity level of primary aluminum produced by these potlines is 99.9%, compared to standard-purity aluminum which is approximately 99.7%. High purity primary aluminum is sold at a premium to standard-purity aluminum. Hawesville’s specially configured facility provides the high-conductivity metal required by Hawesville’s largest customer, Southwire, for its electrical wire and cable products as well as for certain aerospace applications.
In December 2010, we announced plans to restart a potline at our Hawesville facility that had been curtailed in March 2009. Restarting the curtailed potline brought Hawesville essentially to full production capacity by December 31, 2011. Hawesville's slower than anticipated return to full stable operations following the restart of the curtailed potline in 2011 resulted in lower than expected domestic production for the year. In addition, the plant experienced reduced production efficiencies and higher costs related to the unstable conditions which prevailed during the majority of the year. Though the plant has essentially returned to full production, we expect that Hawesville’s operations will continue to be negatively impacted by production inefficiencies through the first quarter of 2012.

Table of Contents
Metal Sales Agreement. Hawesville has an aluminum sales contract with Southwire (the “Southwire Metal Agreement”). The Southwire Metal Agreement extends through December 2013. The price for molten aluminum delivered to Southwire is variable and is determined by reference to the U.S. Midwest Market Price. Under the contract, Hawesville supplies between 220 and 240 million pounds (approximately 100,000 to 109,000 metric tons) of high-conductivity molten aluminum annually to Southwire’s adjacent wire and cable manufacturing facility. In addition, we have contracted with Glencore to sell all primary aluminum we produce in the U.S., less existing agreements and high purity sales, through December 2012 (the “Glencore Sweep Agreement”). The Glencore Sweep Agreement provides for variable pricing determined by reference to the U.S. Midwest Market Price. More information on the Southwire Metal Agreement and Glencore Sweep Agreement is available under “Primary Aluminum Sales Contracts” in Note 16 Forward delivery contracts and financial instruments of the consolidated financial statements included herein.
Alumina. Hawesville receives its alumina supply from Glencore under our long-term alumina purchase agreement.
Power. Kenergy, a subsidiary of Big Rivers, provides Hawesville’s electrical power under the Big Rivers Agreement. The Big Rivers Agreement provides for long-term cost-based power through December 31, 2023. See Long-term Supply Contracts - Electrical Power Supply Agreements above for additional information.
CAKY has a contingent obligation to repay E.ON related to the unwind of a previous power agreement, subject to certain conditions. See Note 6 Debt for additional information about the contingent obligation.
Employees. The bargaining unit employees at Hawesville are represented by the USWA. The collective bargaining agreement, which covers all of the represented hourly employees at Hawesville, expires in March 2015.
Mt. Holly
Mt. Holly, located in Mt. Holly, South Carolina, was built in 1980 and is the most recently constructed aluminum reduction facility in the United States. The facility consists of two potlines with a total rated production capacity of 224,000 mtpy and casting equipment used to cast molten aluminum into standard-grade ingot, extrusion billet and other value-added primary aluminum products. Value-added primary aluminum products are sold at a premium to standard-grade primary aluminum. Our 49.7% interest represents approximately 111,000 mtpy of the facility’s annual production capacity.
Our interest in Mt. Holly is held through our subsidiary, Berkeley Aluminum, Inc. (“Berkeley”). Under the Mt. Holly ownership structure, we hold an undivided 49.7% interest in the property, plant and equipment comprising the aluminum reduction operations at Mt. Holly and an equivalent share in the general partnership responsible for the operation and maintenance of the facility. Alcoa owns the remaining 50.3% interest in Mt. Holly and an equivalent share of the operating partnership. Under the terms of the operating partnership, Alcoa is responsible for operating and maintaining the facility. Each owner supplies its own alumina for conversion to primary aluminum and is responsible for its proportionate share of operational and maintenance costs.
Metal Sales Agreements. We have a contract to sell to Glencore 20,400 mtpy of primary aluminum through December 31, 2013, produced at Mt. Holly or Hawesville at a price determined by reference to the U.S. Midwest Market Price, subject to an agreed cap and floor as applied to the U.S. Midwest Premium (the “Glencore Metal Agreement”). Under the Glencore Sweep Agreement, any additional primary aluminum produced in the U.S. (including Mt. Holly), less existing agreements and high purity sales, will be sold to Glencore at variable pricing determined by reference to the U.S. Midwest Market Price. More information on the Glencore Metal Agreement and Glencore Sweep Agreement is available under “Primary Aluminum Sales Contracts” in Note 16 Forward delivery contracts and financial instruments of the consolidated financial statements included herein.

Alumina. Substantially all of our alumina requirements for Mt. Holly are provided by Trafigura AG under an agreement that extends through 2013. The pricing for alumina under our contract with Trafigura is variable and based on the LME price for primary aluminum.
Power. Mt. Holly purchases all of its power requirements from Santee Cooper under a take-or-pay service agreement that runs through 2015. See Long-term Supply Contracts - Electrical Power Supply Agreements above for additional information.
Employees. The employees at Mt. Holly are employed by Alcoa and are not unionized.
Ravenswood
The Ravenswood facility is owned and operated by our subsidiary, Century Aluminum of West Virginia, Inc. Built in 1957, Ravenswood has four potlines with a production capacity of 170,000 metric tons. The facility is located adjacent to the Ohio River near Ravenswood, West Virginia.
In February 2009, we conducted an orderly curtailment of the plant operations at Ravenswood. We may restart the curtailed operations upon the realization of several objectives, including a new power agreement which would provide for flexibility in Ravenswood’s cost structure under adverse industry conditions as well as a new labor agreement.
Legislation has been passed in West Virginia that gives us the ability to enter into discussions with the public service commission in regard to an enabling power contract for the curtailed plant. We are currently engaged in discussions with the utility as well as the labor union. Until those discussions are further progressed it is not possible to predict when or if a restart of the plant might occur.
Power. Appalachian Power Company (“APCo”) supplies all of Ravenswood’s power requirements under an agreement at prices set forth in published tariffs, which are subject to change. In July 2006, the Public Service Commission of the State of West Virginia approved a special rate mechanism in connection with an increase in the applicable tariff rates. Under the special rate mechanism, Ravenswood may be excused from or may defer the payment of the increase in the tariff rate if aluminum prices as quoted on the LME fall below pre-determined levels.
Employees. The bargaining unit employees at Ravenswood represented by the USWA were under a labor agreement that expired in August 2010. Negotiations for a new labor agreement are ongoing.
Amendments to retiree medical benefits. As of January 1, 2011, CAWV no longer provides retiree medical benefits to active salaried CAWV personnel or any other personnel who retired prior to November 1, 2010. CAWV has made no commitments as to the future status of retiree medical benefits for hourly personnel who are currently covered by an active medical program.
Helguvik project
The Helguvik project site is located approximately 30 miles from the city of Reykjavik, Iceland and is owned and would be operated through our Nordural Helguvik ehf subsidiary. This site provides a flat location and existing harbor, as well as proximity to the international airport, the capital and other industry.

We commenced construction of the Helguvik project in June 2008. We significantly reduced construction activity and spending on the project in late 2008 in response to the global financial crisis and deterioration of Icelandic economic and political conditions. Construction activity and spending on the project remains significantly curtailed pending confirmation from the contracted power suppliers that they will be able to deliver the required power per an agreed schedule. See “Long-term Supply Contracts – Electrical Power Supply Agreements” and Item 1A, “Risk Factors – If we are unable to procure a reliable source of power the Helguvik project may not be feasible.” We are working to complete the activities required for a full restart of construction activity at Helguvik as soon as we have resolution of the power supply issues. Capitalized costs for the project through December 31, 2011 were approximately $138 million, withapproximately $13 million incurred during 2011.
See Item 1A, “Risk Factors – Construction at our Helguvik smelter site is under review. Substantial delay in the completion of this project may increase its cost and impose other risks to completion that are not foreseeable at this time” and “If we are unable to procure a reliable source of power the Helguvik project may not be feasible.”
Power Supply Agreements. Nordural Helguvik has signed electrical power supply agreements with HS and OR to supply power to the Helguvik smelter. Each of HS and OR have alleged that certain conditions to the delivery of power under the power supply agreements have not been satisfied. The first stage of power under the OR power purchase agreement (approximately 47.5 MW) became available in the fourth quarter of 2011. This power is being utilized at Grundartangi until the first stage of the Helguvik project has been completed. No other power is currently available under either power purchase agreement.
Helguvik Investment Agreement. An Enabling Act for an Investment Agreement with the Government of Iceland for Helguvik, which governs certain meaningful aspects of the project such as the fiscal regime, was approved in April 2009 by the Icelandic Parliament. In July 2009, the European Surveillance Authority approved the Investment Agreement and in August 2009 Nordural Helguvik ehf and the Icelandic Minister of Industry executed the agreement. Among other things, the Investment Agreement includes a commitment by the Government of Iceland to assist us in obtaining necessary regulatory approvals for completion of the Helguvik project.
Environmental Impact Assessment. In October 2007, Nordural received a positive opinion from the Icelandic Planning Agency on the Environmental Impact Assessment (“EIA”) for the proposed Helguvik smelter.
Transmission Agreement. Nordural Helguvik entered into a transmission agreement with Landsnet hf (“Landsnet”) to provide an electrical power transmission system to the Helguvik project. Landsnet is the company responsible for operating and managing Iceland’s transmission system. As a result of delays in construction of the Helguvik project, the parties are currently in discussions with respect to the timeline for construction of the transmission system.
Operating License. In September 2008, the Environmental Agency of Iceland issued an Operating License for the Helguvik smelter project. The license authorizes production of up 250,000 mtpy.
Other agreements. We have also entered into a site and harbor agreement with respect to the Helguvik project.

| Joint Venture Facility

Baise Haohai Carbon Company, Ltd.
In 2008, we entered into a joint venture agreement whereby we acquired a 40% stake in Baise Haohai Carbon Co., Ltd. (“BHH”), a carbon anode and cathode facility located in the Guangxi Zhuang Autonomous Region of south China. The BHH facility has an anode production capacity of 180,000 mtpy and a cathode baking and graphitization capacity of 20,000 mtpy. Construction of the facility was completed in 2008.
We paid $27.6 million for the investment and loaned BHH an additional $9.4 million. Through December 2011, BHH has repaid $6.2 million on the loan. Our investment in the joint venture is accounted for using the equity method of accounting with results of operations reported on a one-quarter lag.
Anode agreement. BHH provides anodes to Grundartangi under a long-term agreement through 2012, renewable through December 31, 2015.

| Environmental Matters

We are subject to various environmental laws and regulations both in the U.S. and in other countries. We have spent, and expect to spend, significant amounts for compliance with those laws and regulations. In addition, some of our past manufacturing activities have resulted in environmental consequences which require remedial measures. Under certain environmental laws, which may impose liability regardless of fault, we may be liable for the costs of remediation of contaminated property, including our current and formerly owned or operated properties or adjacent areas, or for the amelioration of damage to natural resources. We believe, based on currently available information, that our current environmental liabilities are not likely to have a material adverse effect on Century. However, we cannot predict the requirements of future environmental laws and future requirements at current or formerly owned or operated properties or adjacent areas. Such future requirements may result in unanticipated costs or liabilities which may have a material adverse effect on our financial condition, results of operations or liquidity. More information concerning our environmental contingencies can be found in Item 3 Legal Proceedings and in Note 15 Commitments and contingencies to the consolidated financial statements included herein.

| Intellectual Property

We own or have rights to use a number of patents or patent applications relating to various aspects of our operations. We do not consider our business to be materially dependent on any of these patents or patent applications.

| Employees

As of December 31, 2011, we employed approximately 1,300 employees.

| Item 1A. Risk Factors

The following describes certain of the risks and uncertainties we face that could cause our future results to differ materially from our current results and from those anticipated in our forward-looking statements. These risk factors should be considered together with the other risks and uncertainties described in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere herein. This list of significant risk factors is not all-inclusive or necessarily in order of importance.
The cyclical nature of the aluminum industry causes variability in our earnings and cash flows.
Our operating results depend on the market for primary aluminum, which is a highly cyclical commodity with prices that are affected by global demand and supply, political and economic conditions and other related factors. For example, aluminum warehouse inventory levels were at or near historically high levels in 2010 and 2011, which may cause primary aluminum prices to fall as such inventory enters the market. Historically, aluminum prices have been volatile, and we expect such volatility to continue.
Declines in primary aluminum prices reduce our earnings and cash flows. If the price we realize for our products falls below our cost of production, we may choose or be forced to curtail operations to fund our operations. There can be no assurance that we will be able to take actions necessary to curtail operations, if these steps are required. Future downturns in aluminum prices may significantly reduce the amount of cash available to meet our obligations and fund our long-term business strategies and could have a material adverse effect on our business, financial conditions, results of operations and liquidity.
Disruptions to our raw material and electricity supply arrangements could increase our production costs.
Our business depends upon the adequate supply of alumina, electricity, aluminum fluoride, calcined petroleum coke, pitch, finished carbon anodes and cathodes and other raw materials at competitive prices. Disruptions to the supply of these production inputs could occur for a variety of reasons, including disruptions of production at a particular supplier’s facility or power plant, as applicable. For some of these production inputs, such as power and anode supply, we rely on a single or limited number of suppliers.
Any disruption may require us to purchase these products on the spot market on less favorable terms than under our current agreements due to the limited number of suppliers of these products or other market conditions. In addition, we may not be able to obtain alumina in the future at prices that are based on the LME. Because we sell our products based on the LME price for primary aluminum, we would not be able to pass on any increased costs of raw material that are not linked to the LME price to our customers. A disruption in our materials or electricity supply may adversely affect our operating results if we are unable to secure alternate supplies of materials at comparable prices.
Certain of our alumina and electricity supply contracts contain “take-or-pay” obligations.
We have obligations under certain contracts to take-or-pay for specified quantities of alumina and electricity over the term of those contracts regardless of our operating requirements. Our financial position and results of operations may therefore be adversely affected by the market price for alumina and electric power even if we were to curtail unprofitable production capacity (or delay construction of new capacity) as we will continue to incur costs under these contracts to meet or settle our contractual take-or-pay obligations. If we were unable to use such electrical power or raw materials in our operations or sell them at prices consistent with or greater than our contract costs, we could incur significant losses under these contracts. In addition, these commitments may also limit our ability to take advantage of favorable changes in the market prices for electricity or raw materials and may have a material adverse effect on our business, financial position, results of operations and liquidity.

Table of Contents
Increases in electricity costs adversely affect our business.
Electricity represents our single largest operating cost. As a result, the availability of electricity at economic prices is critical to the profitability of our operations. Portions of the contracted cost of the electricity supplied to Mt. Holly and all of Hawesville’s electricity costs vary with the supplier’s costs. An increase in these costs would increase the price these facilities pay for electricity. Costs under the Hawesville and Mt. Holly electricity contracts have substantially increased in recent years with rising fuel prices. As these contracts have take-or-pay type provisions, the financial position, results of operations and cash flows of Hawesville and Mt. Holly may be adversely affected by the price for electric power even if we curtail unprofitable production capacity. Significant increases in electricity costs at any of our operations may have a material adverse effect on our business, financial condition, results of operations and liquidity.
Losses caused by disruptions in our supply of power would adversely affect our operations.
We use large amounts of electricity to produce primary aluminum. Any loss of power which reduces the amperage to our equipment or causes an equipment shutdown would result in a reduction in the volume of molten aluminum produced, and prolonged losses of power may result in the hardening or “freezing” of molten aluminum in the pots where it is produced, which could require an expensive and time consuming restart process. Interruptions in the supply of electrical power to our facilities can be caused by a number of circumstances, including unusually high demand, blackouts, equipment or transformer failure, human error, malicious acts, natural disasters or other catastrophic events. See “Unpredictable events, including natural disasters, dangerous weather conditions, terrorist attacks and political unrest, may adversely affect our ability to conduct business.” At several of our facilities, an alternative supply of power in the event of a disruption may not be feasible. If such a condition were to occur, we may lose production for a prolonged period of time and incur significant losses.
We operate our plants at close to peak amperage. Accordingly, even partial failures of high voltage equipment could affect our production. We maintain property and business interruption insurance to mitigate losses resulting from catastrophic events, but are required to pay significant amounts under the deductible provisions of those insurance policies. In addition, the coverage under those policies may not be sufficient to cover all losses, or may not cover certain events. Certain of our insurance policies do not cover any losses that may be incurred if our suppliers are unable to provide power during periods of unusually high demand. Certain losses or prolonged interruptions in our operations may trigger a default under certain of our outstanding indebtedness and could have a material adverse effect on our business, financial position, results of operations and liquidity.
International operations expose us to political, regulatory, currency and other related risks.
We receive a significant portion of our revenues from our international operations, primarily in Iceland. These operations expose us to risks, including unexpected changes in foreign laws and regulations, political and economic instability, challenges in managing foreign operations, increased costs to adapt our systems and practices to those used in foreign countries, taxes, export duties, currency restrictions, tariffs and other trade barriers, and the burdens of complying with a wide variety of foreign laws. Changes in foreign laws and regulations are generally beyond our ability to control, influence or predict and future adverse changes in these laws could have a material adverse effect on our business, financial condition, results of operations and liquidity.
In addition, we may be exposed to fluctuations in currency exchange rates and, as a result, an increase in the value of foreign currencies relative to the U.S. dollar could increase our operating expenses which are denominated and payable in those currencies. As we continue to explore other opportunities outside the U.S., including the Helguvik project, our currency risk with respect to the Icelandic Krona and other foreign currencies will significantly increase.

Table of Contents
If economic, financial and political conditions in Iceland were to deteriorate, our financial position and results of operations could be adversely impacted.
Iceland is important to our business. Disruptions in Iceland’s economic, financial and political systems have decreased the stability of Iceland’s economy and financial markets and made cash management activities in Iceland more challenging. For example, the Icelandic government and the Central Bank of Iceland are restricting the free transfer of funds outside of Iceland and, specifically, foreign currency within and outside of Iceland. While we are currently exempt from these foreign currency rules, we cannot control further actions by the Central Bank of Iceland which might restrict our ability to transfer funds through the Icelandic banking system and outside of Iceland. While we currently maintain essentially all of our Icelandic operating funds in accounts outside of Iceland, and are receiving substantially all of our customer payments in such accounts, a portion of our funds remain in the Icelandic banks to meet local working capital requirements. In addition, as payables become due in Iceland, we must transfer funds through the Icelandic banking system. If economic, financial or political conditions in Iceland deteriorate, or if counterparties and lenders become unwilling to engage in normal banking relations with and within Iceland, our ability to operate our Grundartangi smelter, including paying vendors, processing payroll and receiving payments, as well as our ability to complete the Helguvik project could be adversely impacted, any of which could have a material adverse effect on our business, financial condition, results of operations and liquidity.
Curtailment of unprofitable aluminum production at our U.S. facilities could have a material adverse effect on our business, financial condition, results of operations and liquidity.
Curtailing unprofitable production to reduce our operating costs requires us to incur substantial expense, both at the time of the curtailment and on an ongoing basis. Our facilities are subject to contractual and other fixed costs that continue even if we curtail operations at these facilities. These costs reduce the cost saving advantages of curtailing unprofitable aluminum production. In addition, the prospect of these costs and our joint ownership of certain of our operations limit our flexibility to curtail unprofitable production.
If we are unable to realize the intended effects of any production curtailment, including at our currently curtailed Ravenswood facility, or if any production curtailment does not achieve sufficient reduction in operating expenses, we may have to seek bankruptcy protection for some or all of our U.S. subsidiaries and/or may be forced to divest some or all of our U.S. subsidiaries. If we were to seek bankruptcy protection for these subsidiaries, we would face additional risks. Such action could cause concern among our customers and suppliers generally, distract our management and our other employees and subject us to increased risks of lawsuits. Other negative consequences could include negative publicity, which could have a material negative impact on the trading price of our securities and negatively affect our ability to raise capital in the future.
Any curtailments of our U.S. operations, or actions taken to seek bankruptcy protection or divest some or all of our U.S. subsidiaries, could have a material adverse effect on our business, financial condition, results of operations and liquidity.
We require substantial resources to pay our operating expenses and fund our capital expenditures.
We require substantial resources to pay our operating expenses and fund our capital expenditures, including construction at our Helguvik smelter site and the investment programs at our Grundartangi and Hawesville smelters. In addition, if we were to resume operations at our Ravenswood smelter, we would incur substantial capital expenditures, working capital funding and operating expenses. If we are unable to generate funds from our operations to pay our operating expenses and fund our capital expenditures and other obligations, our ability to continue to meet these cash requirements in the future could require substantial liquidity and access to sources of funds, including from capital and credit markets. Changes in global economic conditions, including material cost increases and decreases in economic activity, and the success of plans to manage costs, inventory and other important elements of our business, may significantly impact our ability to generate funds from operations. If, among other factors, primary aluminum prices were to decline, our costs are higher than contemplated, we suffer unexpected production outages, or Icelandic laws change and either increase our tax obligations or limit our access to cash flow from our Icelandic operations, we would need to identify additional sources of liquidity.

Table of Contents
If funding is not available when needed, or is available only on unacceptable terms, we may be unable to respond to competitive pressures, take advantage of market opportunities or fund operations, capital expenditure or other obligations, any of which could have a material adverse effect on our business, financial condition, results of operations and liquidity.
Our business and growth prospects may be negatively impacted by past or future reductions in our capital expenditures or curtailment of production capacity.
In response to the global economic downturn and related disruptions in the financial markets, in 2008 and 2009 we curtailed significant production capacity and reduced capital expenditures. Certain of these assets remain curtailed or delayed, including our Ravenswood smelter and the development of our Helguvik smelter. Our ability to take advantage of improved market conditions may be constrained by these earlier curtailments, capital expenditure restrictions and other similar actions, and the long-term value of our business could be adversely impacted. Our position in relation to our competitors may also deteriorate. We may also be required to address commercial and political issues in relation to our reductions in capital expenditures or operational curtailment in certain of the jurisdictions in which we operate. In addition, if we do not eventually resume operations at Ravenswood, we may be required to recognize a loss related to all or a portion of the assets of this facility. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and liquidity.
Construction at our Helguvik smelter site has been significantly curtailed. Substantial delay in the completion of this project may increase its cost and impose other risks to completion that are not foreseeable at this time.
Nordural Helguvik ehf, our indirect, wholly owned subsidiary, has significantly curtailed construction activity and spending at our Helguvik project in response to the recent global economic conditions, Icelandic economic and political conditions and ongoing discussions with the power companies contracted to provide power to the Helguvik project. See “If we are unable to procure a reliable source of power, the Helguvik project may not be feasible,” and “If economic and political conditions in Iceland deteriorate further, our financial position and results of operations could be adversely impacted.” Nordural Helguvik cannot be certain when or if it will restart major construction and engineering activities or ultimately complete the Helguvik project or, if completed, that the Helguvik smelter would operate in a profitable manner. We will not realize any return on our significant investment in the Helguvik project until we are able to commence Helguvik operations in a profitable manner. If we fail to achieve operations at Helguvik, we may have to recognize a loss on our investment, which would have a material adverse impact on our future earnings.
If we decide to proceed with the Helguvik project, this project is subject to various contractual approvals and conditions. Many of the contractual arrangements related to the Helguvik project have time periods for performance. The delay in restarting major construction and completing the Helguvik project has caused Nordural Helguvik to renegotiate and extend, or undertake to renegotiate and extend, existing contractual commitments, including with respect to power, transmission, technology, equipment and construction. There can be no assurance that the contractual arrangements and conditions, including extensions, necessary to proceed with construction of the Helguvik project will be obtained or satisfied on a timely basis or at all. In addition, such approvals or extensions may be subject to conditions that are unfavorable or make the project impracticable or less attractive from a financial standpoint. Even if we receive the necessary approvals and extensions on terms that we determine are acceptable, the construction of this project is a complex undertaking. There can be no assurance that we will be able to complete the project within our projected budget and schedule. To successfully execute this project, we will also need to procure a reliable source of power, arrange additional financing and either enter into tolling arrangements or secure a supply of alumina as well as other raw materials. In addition, unforeseen technical difficulties could increase the cost of the project, delay the project or render the project infeasible.
- 16 -

Table of Contents
We intend to finance our future capital expenditures from future capital raising, available cash and cash flow from operations. We may be unable to raise additional capital, or do so on attractive terms, due to a number of factors, including a lack of demand, poor economic conditions, interruptions in the capital markets, unfavorable interest rates or our financial condition or credit rating at the time. If additional capital resources are unavailable, we may further curtail construction and development activities.
Further delay in the completion of the project or increased costs could have a material adverse effect on our business, financial condition, results of operations and liquidity.
If we are unable to procure a reliable source of power, the Helguvik project may not be feasible.
The Helguvik project will require generation and transmission of a substantial amount of electricity to power the smelter. Nordural Helguvik has entered into agreements with two providers of geothermal power, HS and OR. Each of HS and OR has alleged that certain conditions to the delivery of power under the power agreements have not yet been satisfied. If we are unable to reach agreement with each of HS and OR, we may have to seek alternative sources of power, incur substantially increased power costs or further curtail construction activities of the Helguvik project. Due to the limited number of Icelandic power providers with resources sufficient to provide power to the Helguvik project (only three are currently in operation in Iceland), we may find it difficult or impossible to procure additional sources of power if HS and OR do not perform under their existing agreements and may be unable to complete construction of the smelter. If we agree to pay increased prices for power or substantially delay or are unable to complete the Helguvik project, we may have to recognize a substantial loss on our investment. Any failure to complete the Helguvik project could have a material adverse effect on our business, financial condition, results of operations and liquidity.
The generation of the contracted power for the Helguvik project will also require successful development of new geothermal energy sources within designated areas in Iceland and completion of the necessary transmission infrastructure to service the Helguvik project. If there are construction delays or technical difficulties in developing these new geothermal energy sources or transmission infrastructure, power may be delayed or may not be available. Development of the generation and transmission infrastructure is expensive and requires significant resources from the power and transmission providers. Factors which could delay or impede the generation and transmission of electric power are substantially beyond our ability to control, influence or predict, including the power and transmission providers’ ability to finance and obtain necessary permits, real property and other rights for the development of new geothermal energy sources and associated transmission infrastructure. In addition, if Nordural Helguvik is unable to proceed with the Helguvik project, it may incur significant reimbursement obligations for certain costs incurred by third party providers under transmission and other agreements entered into in connection with the Helguvik project and remain subject to significant power commitments already confirmed under its agreement with OR. If the power or transmission providers are unable to provide or transmit the contracted amounts of power, such failure could substantially delay or make the Helguvik project infeasible and could have a material adverse effect on our business, financial condition, results of operations and liquidity.
Union disputes could raise our production costs or impair our production operations.
The bargaining unit employees at our Grundartangi, Hawesville and Ravenswood smelters are represented by labor unions. If we fail to maintain satisfactory relations with any labor union representing our employees, our labor contracts may not prevent a strike or work stoppage at any of these facilities in the future. Any threatened or actual work stoppage in the future or inability to renegotiate our collective bargaining agreements could prevent or significantly impair our ability to conduct production operations at our unionized facilities, which could have a material adverse effect on our financial condition, results of operations and liquidity.
- 17 -

Table of Contents
We could be adversely affected by the loss of a major customer or changes in the business or financial condition of our major customers.
In 2011, we derived approximately 80% of our consolidated sales from our three major customers: Southwire Glencore and BHP Billiton. We currently have long-term primary aluminum sales or tolling contracts with each of these customers. However, a significant downturn or further deterioration in the business or financial condition of one of these major customers could affect our results of operations. In addition, a loss of any of these customers could have a material adverse effect on our financial condition, results of operations and liquidity.
Our ability to access the credit and capital markets on acceptable terms may be limited due to our credit ratings, our financial condition or the deterioration of these markets.
Our credit rating was adversely affected by the downturn in global economic and financial conditions, curtailment of our Ravenswood smelter and the substantial levels of our existing indebtedness. Our availability under our revolving credit facility is dependent on our domestic accounts receivable and inventory which secure the facility. Curtailment of production capacity at Ravenswood has reduced the amount of domestic accounts receivable and inventory available to secure this facility and further curtailments of domestic production capacity could further reduce availability under our revolving credit facility. Our existing credit ratings, or any future negative actions the credit agencies may take, could negatively affect our ability to access the credit and capital markets in the future and could lead to worsened trade terms, increasing our liquidity needs. An inability to access capital and credit markets when needed could have a material adverse effect on our business, financial condition, results of operations and liquidity.
We may be unable to continue to compete successfully in the highly competitive markets in which we operate.
We are engaged in a highly competitive industry. Aluminum also competes with other materials, such as steel, copper, plastics, composite materials and glass, among others, for various applications. Many of our competitors are larger than us and have greater financial and technical resources than we do. These larger competitors may be better able to withstand reductions in price or other adverse industry or economic conditions. Similarly, competitors with superior cost positions to ours may be better able to withstand reductions in price or other adverse industry or economic conditions. If we are not able to compete successfully, our business, financial condition, results of operations and cash flows could be materially and adversely affected.
Because we own less than a majority of some of our operating assets, we cannot exercise complete control over their operations.
We have limited control over the operation of some of our operating assets, including the Mt. Holly smelter and the BHH carbon anode and cathode facility, because we beneficially own less than a majority of the ownership interests in such assets. While we seek to exert as much influence with respect to the management and operation of such assets as possible, we are dependent on our co-owners to operate such assets. Our co-owners may not have the level of experience, technical expertise, human resource management and other attributes to operate these assets optimally. In addition, our co-owners may have interests, objectives and incentives with respect to such assets that differ from our own.

Table of Contents
We require significant cash flow to meet our debt service requirements, which increases our vulnerability to adverse economic and industry conditions, reduces cash available for other purposes and limits our operational flexibility.
As of December 31, 2011, we had an aggregate of approximately $257 million principal amount of outstanding debt. We may incur additional debt in the future.
The level of our debt could have important consequences, including:

| · | increasing our vulnerability to adverse economic and industry conditions;

| · | reducing cash flow available for other purposes, including capital expenditures, acquisitions, dividends, working capital and other general corporate purposes, because a substantial portion of our cash flow from operations must be dedicated to servicing our debt; and

| · | limiting our flexibility in planning for, or reacting to, competitive and other changes in our business and the industry in which we operate.

We have various obligations to make payments in cash that will reduce the amount of cash available to make interest payments required on our outstanding debt and for other uses. Our industrial revenue bonds (“IRBs”) and any future borrowings on our credit facility are at variable interest rates, and future borrowings required to fund working capital at our businesses, construction of the Helguvik project, acquisitions, or other strategic opportunities may be at variable rates. An increase in interest rates would increase our debt service obligations under these instruments, further limiting cash flow available for other uses. In addition to our debt, we have liabilities and other obligations which could reduce cash available for other purposes and could limit our operational flexibility.
Our ability to pay interest on and to repay or refinance our debt and to satisfy other commitments will depend upon our access to additional sources of liquidity and future operating performance, which is subject to general economic, financial, competitive, legislative, regulatory, business and other factors, including market prices for primary aluminum, that are beyond our control. Accordingly, there can be no assurance that our business will generate sufficient cash flow from operations or that future borrowings will be available to us in an amount sufficient to enable us to pay debt service obligations, or to fund our other liquidity needs. If we are unable to meet our debt service obligations or fund our other liquidity needs, we could attempt to restructure or refinance our debt or seek additional equity or debt capital. There can be no assurance that we would be able to accomplish those actions on satisfactory terms, or at all, and if we are unable to ultimately meet our debt service obligations and fund our other liquidity needs, it may have a material adverse effect on our business, financial condition, results of operations and liquidity.
Despite our substantial level of debt, we may incur more debt, which could exacerbate any or all of the risks described above.
We may incur substantial additional debt in the future. Although the loan and security agreement governing our revolving credit facility and the indenture governing the 8.0% Senior Secured Notes due 2014 (the “8.0% Notes”) limits our ability and the ability of certain of our subsidiaries to incur additional debt, these restrictions are subject to a number of qualifications and exceptions and, under certain circumstances, debt incurred in compliance with these restrictions could be substantial. For example, as of December 31, 2011, approximately $58 million was available to us for borrowing under our revolving credit facility. In addition, the loan and security agreement governing our revolving credit facility and the indenture governing the 8.0% Notes do not prevent us from incurring certain obligations that do not constitute debt as defined in these agreements. To the extent that we incur additional debt or such other obligations, the risks associated with our substantial debt described above, including our possible inability to service our debt or other obligations, would increase.
- 19 -

Table of Contents
Our debt instruments subject us to covenants and restrictions
Our existing debt instruments contain various covenants that restrict the way we conduct our business and limit our ability to incur debt, pay dividends and engage in transactions such as acquisitions and investments, among other things, which may impair our ability to obtain additional liquidity and grow our business. Any failure to comply with those covenants would likely constitute a breach under such debt instruments which may result in the acceleration of all or a substantial portion of our outstanding indebtedness and termination of commitments under our revolving credit facility. If our indebtedness is accelerated, we may be unable to repay the required amounts and our secured lenders could foreclose on any collateral securing our secured debt. Any of the foregoing actions could have a material adverse effect on our business, financial condition, results of operations and liquidity.
We depend upon intercompany transfers from our subsidiaries to meet our debt service obligations.
We are a holding company and conduct all of our operations through our subsidiaries. Our ability to meet our debt service obligations depends upon the receipt of intercompany transfers from our subsidiaries. Subject to the restrictions contained in our revolving credit facility and the indenture governing our 8.0% Notes, future borrowings by our subsidiaries could contain restrictions or prohibitions on intercompany transfers by those subsidiaries. In addition, under applicable law, our subsidiaries could be limited in the amounts that they are permitted to pay as dividends on their capital stock. For example, the Icelandic government and the Central Bank of Iceland are currently restricting the free transfer of funds outside of Iceland. While we are currently exempt from these foreign currency rules, we cannot control further actions by the Central Bank of Iceland, which might restrict our ability to transfer funds through the Icelandic banking system and outside of Iceland.
Future declines in the financial markets and/or our curtailment actions could have significant and adverse effects on our pension funding obligations.
We maintain two qualified defined benefit plans, and contribute to a third, on behalf of our employees. As a result of poor investment returns, the benefit plans we maintain were underfunded as of December 31, 2011. If capital markets experience further significant losses, pension fund balances would likely fall and additional cash contributions to the pension funds will be required. Additionally, in June 2011, the Pension Benefit Guaranty Corporation (the “PBGC”) informed us that it believed that a “cessation of operations” under the Employee Retirement Income Security Act of 1974 (“ERISA”) had occurred at our Ravenswood facility as a result of the curtailment of operations at the facility and requested that we engage in discussions with the PBGC relating thereto. While we do not believe a “cessation of operations” under ERISA has occurred, if such a determination is ultimately made by the PBGC, it may be necessary for Century Aluminum of West Virginia to accelerate the timing of additional contributions to certain of its defined pension plans or post other collateral with the PBGC or negotiate an alternative agreement.
We may be required to write down the book value of certain assets.
We are required to perform various analyses related to the carrying value of various assets whenever events or circumstances indicate that their net carrying amount may not be recoverable. Given the recent lack of profitability of certain of our production facilities and recent global economic conditions, which in part drive assumptions for the future in such analyses, we could have significant adjustments in the carrying value for certain assets. In the future, we will continue to evaluate our assets for impairments and valuation allowance, which could be significant. Any such adjustments would be in the form of a non-cash charge which would reduce our earnings and reduce our balance of retained earnings.

Climate change, climate change legislation or regulations and greenhouse effects may adversely impact our operations.
Climate change and greenhouse gas emissions are the subject of significant attention in the countries in which we operate and a number of governments or governmental bodies in these countries have introduced or are contemplating legislative and regulatory change in response to the potential impacts of climate change. For example, as a member of the European Economic Area and a signatory to the Kyoto Protocol, Iceland has implemented legislation to abide by the Kyoto Protocol and prepare to abide by Directive 2003/87/EC of the European Parliament which establishes a “cap and trade” scheme for greenhouse gas emission allowance trading. Because Iceland was granted emissions allowances under the Kyoto Protocol through 2012, Iceland has not yet implemented Directive 2003/87/EC, but it is anticipated that Iceland will begin complying with the Directive in 2013. In addition, we are aware of proposed U.S. legislation that if enacted, among other things, would implement a “cap and trade” system of allowances and credits in the United States.
Implementation of these potential regulatory changes or others is uncertain and may be either voluntary or legislated and may impact our operations directly or indirectly through customers or our supply chain. As a result of the foregoing, we may incur increased capital expenditures resulting from required compliance with such regulatory changes, increased energy costs, costs to purchase or profits from sales of, allowances or credits under a “cap and trade” system, increased insurance premiums and deductibles, a change in competitive position relative to industry peers and changes to profit or loss arising from increased or decreased demand for goods produced by us and indirectly, from changes in costs of goods sold. For example, “cap and trade” legislation may impose significant additional costs to our power suppliers that could lead to significant increases in our energy costs. In addition, the potential physical impacts of climate change on our operations are highly uncertain and will be particular to the geographic circumstances. These may include changes in rainfall patterns, shortages of water or other natural resources, changing sea levels, changing storm patterns and intensities, and changing temperature levels. Any adverse regulatory and physical changes may have a material adverse effect on our business, financial condition, results of operations and liquidity.
We are subject to a variety of environmental laws and regulations that could result in costs or liabilities.
We are obligated to comply with various federal, state and other environmental laws and regulations, including the environmental laws and regulations of the United States, Iceland, China and the EU. Environmental laws and regulations may expose us to costs or liabilities relating to our manufacturing operations or property ownership. We incur operating costs and capital expenditures on an ongoing basis to comply with applicable environmental laws and regulations. In addition, we are currently and may in the future be responsible for the cleanup of contamination at some of our current and former facilities or for the amelioration of damage to natural resources. If more stringent compliance or cleanup standards under environmental laws or regulations are imposed, previously unknown environmental conditions or damages to natural resources are discovered or alleged, or if contributions from other responsible parties with respect to sites for which we have cleanup responsibilities are not available, we may be subject to additional liability, which may have a material adverse effect on our business, financial condition, results of operations and liquidity. Further, additional environmental matters for which we may be liable may arise in the future at our present sites where no problem is currently known, with respect to sites previously owned or operated by us, by related corporate entities or by our predecessors, or at sites that we may acquire in the future. In addition, overall production costs may become prohibitively expensive and prevent us from effectively competing in price sensitive markets if future capital expenditures and costs for environmental compliance or cleanup are significantly greater than current or projected expenditures and costs.
Unpredictable events, including natural disasters, dangerous weather conditions, terrorist attacks and political unrest, may adversely affect our ability to conduct business.
We receive a significant portion of our revenues from operations in areas that have heightened risk of natural disasters, including Iceland. Iceland suffered several natural disasters in 2010 and 2011, including significant volcanic eruptions and earthquakes. In addition, our Grundartangi smelter lost power for approximately three hours in January 2012 as the result of damage sustained due to abnormal and extreme weather conditions at an offsite electrical substation owned and operated by the national power grid operator.

Table of Contents
Future unpredictable events, including natural disasters, dangerous weather conditions, terrorist attacks and political unrest, may adversely affect our ability to conduct business by causing disruptions in Icelandic, Chinese, U.S. or global economic conditions, inflicting loss of life, damaging property and requiring substantial capital expenditures and operating expenses to remediate damage and restore operations at our production facilities.
Acquisitions may present difficulties.
We have a history of making acquisitions and we expect to opportunistically seek to make acquisitions in the future. We are subject to numerous risks as a result of our acquisition strategy, including the following:

| · | we may spend time and money pursuing acquisitions that do not close;

| · | acquired companies may have contingent or unidentified liabilities;

| · | it may be challenging for us to manage our existing business as we integrate acquired operations;

| · | we may not achieve the anticipated benefits from our acquisitions; and

| · | management of acquisitions will require continued development of financial controls and information systems, which may prove to be expensive, time-consuming and difficult to maintain.

Accordingly, our past or future acquisitions might not ultimately improve our competitive position and business prospects as anticipated and may subject us to additional liabilities that could have a material adverse effect on our business, financial condition, results of operations and liquidity.
Any restart of the Ravenswood smelter would involve significant risks and uncertainties
In 2009, we curtailed all operations at our Ravenswood smelter. Any potential restart of operations at the Ravenswood smelter would involve significant risks and uncertainties, including:

| · | we may spend time and incur significant costs and liabilities pursuing a restart that does not occur or that does not achieve the anticipated benefits; and

| · | it may be challenging for us to manage our existing business as we restart operations at Ravenswood.

Accordingly, any potential restart of operations at Ravenswood might not ultimately improve our competitive position and business prospects as anticipated and may subject us to additional liabilities that could have a material adverse effect on our business, financial condition, results of operations and liquidity.
Our ability to utilize certain net operating loss carryforwards to offset future taxable income may be significantly limited if we experience an “ownership change” under the Internal Revenue Code.
As of December 31, 2011, we had net operating loss carryforwards of approximately $1.4 billion, after adjusting for losses carried back to previous tax years, which could offset future taxable income. Our ability to utilize our deferred tax assets to offset future taxable income may be significantly limited if we experience an “ownership change” as defined in Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”). In general, an ownership change would occur if our “five−percent shareholders,” as defined under the Code, collectively increase their ownership in us by more than 50 percentage points over a rolling three−year period. Future transactions in our stock that may not be in our control may cause us to experience an ownership change and thus limit our ability to utilize net operating losses, tax credits and other tax assets to offset future taxable income.

Provisions in our charter documents and state law may make it difficult for others to obtain control of Century Aluminum, even though some stockholders may consider them to be beneficial; Glencore’s ownership interest in us may also deter any change in control of us.
Certain provisions of our restated certificate of incorporation and amended and restated bylaws, as well as provisions of the Delaware General Corporation Law, may have the effect of delaying, deferring or preventing a change in control of Century, including transactions in which our stockholders might otherwise have received a substantial premium for their shares over then current market prices. For examples, these provisions:

| · | give authority to our board of directors to issue preferred stock and to determine the price, rights, preferences, privileges and restrictions of those shares without any stockholder vote;

| · | provide for a board of directors consisting of three classes, each of which serves for a different three-year term;

| · | require stockholders to give advance notice prior to submitting proposals for consideration at stockholders’ meetings or to nominate persons for election as directors; and

| · | restrict certain business combinations between us and any person who beneficially owns 10% or more of our outstanding voting stock.

In addition, while our Tax Benefit Preservation Plan expired in 2010, our board of directors could re-implement the Tax Benefit Preservation Plan or other similar plan that would cause substantial dilution to any person or group who attempts to acquire a significant interest in us without advance approval from our board of directors.
While these provisions have the effect of encouraging persons seeking to acquire control of our company to negotiate with our board of directors, they could enable the board of directors to hinder or frustrate a transaction that some, or a majority, of the stockholders might believe to be in their best interests and, in that case, may prevent or discourage attempts to remove and replace incumbent directors.
Our relationship with Glencore may also deter a takeover. As of December 31, 2011, we believe that Glencore beneficially owned, through its common stock, approximately 42% of our issued and outstanding common stock and, through its ownership of common and preferred stock, an overall 46% economic ownership of Century. In addition, four members of our Board of Directors are employees or former employees of Glencore.

| Item 1B. Unresolved Staff Comments

We have no unresolved comments from the staff of the SEC.

| Item 2. Properties

We own the property on which our Hawesville and Ravenswood facilities are located. The site on which the Grundartangi facility is situated is leased from Faxafloahafnir sf under a long-term lease that runs through 2020, renewable at our option. The site for our Helguvik project is leased from Reykjaneshofn, an independent public authority owned by the Municipality of Reykjanesbaer, under a long-term lease expected to run through 2060, with an automatic extension provision. Our corporate offices are subject to an operating lease that expires in June 2015. We hold a 49.7% interest in a partnership which operates the Mt. Holly facility and a 49.7% undivided interest in the property on which the Mt. Holly facility is located. The remaining interest in the undivided property at Mt. Holly is owned by Alumax of South Carolina, Inc., a subsidiary of Alcoa.
Except for our Ravenswood facility, which was fully curtailed in February 2009, all of our facilities are operating above, at or near their productive capacity. We believe all of our facilities are suitable and adequate for our current operations. Additional information about the age, location, and productive capacity of our facilities is available in the “Overview” section of Item 1, “Business.”

| Item 3. Legal Proceedings

We have pending against us or may be subject to various lawsuits, claims and proceedings related primarily to employment, commercial, environmental, safety and health matters. Although it is not presently possible to determine the outcome of these matters, management believes the ultimate disposition will not have a material adverse effect on our financial condition, results of operations, or liquidity.
In November 2011, we were named as a defendant in a lawsuit filed by our former Chief Executive Officer, Logan Kruger, alleging breach of contract and wrongful termination in violation of public policy. The lawsuit alleges that Century anticipatorily breached the employment and severance protection agreements between Century and Mr. Kruger and that Century is obligated to make various severance payments in excess of $20 million to Mr. Kruger under such agreements. In addition, the complaint seeks unspecified damages, including exemplary and punitive damages, for wrongful termination, as well as costs and attorneys’ fees. We believe these claims are without merit and intend to vigorously defend our self against them. The matter is in a preliminary stage, and we cannot predict the ultimate outcome of this action or estimate a range of possible losses relating to this matter at this time.
In March 2011, the purported stockholder class actions pending against us consolidated as In re: Century Aluminum Company Securities Litigation were dismissed with prejudice by the United States District Court for the Northern District of California. The plaintiffs in the class actions allege that we improperly accounted for cash flows associated with the termination of certain forward financial sales contracts which accounting allegedly resulted in artificial inflation of our stock price and investor losses. Plaintiffs are seeking rescission of our February 2009 common stock offering, unspecified compensatory damages, including interest thereon, costs and expenses and attorneys’ fees. In March 2011, plaintiffs filed a notice of appeal to the order and judgment entered by the court dismissing their claims. The notice of appeal remains pending before the U.S. Court of Appeals for the Ninth Circuit.

We produce primary aluminum. The aluminum industry is cyclical and the price of primary aluminum (which trades as a commodity) is determined by global supply and demand. The key determinants of our results of operations and cash flow from operations are as follows:

| · | Our selling price is based on the LME price of primary aluminum and is influenced by regional premiums and, at certain times, by fixed price sales contracts. In addition, we earn further premiums on value-added products.

| · | In normal circumstances, our facilities operate at or near capacity, and fluctuations in volume, other than through curtailments, acquisitions or expansion, generally are small.

| · | The principal components of cost of goods sold are alumina, electrical power, labor and carbon products, which in aggregate exceed 80% of our cost of goods sold. Many of these costs are governed by long-term contracts.

Shipment volumes, average realized price and cost of goods sold per metric ton shipped are our key performance indicators. Revenue can vary significantly from period to period due to the fluctuations in the LME and Midwest price of primary aluminum. Any adverse changes in the conditions that affect shipment volumes or the market price of primary aluminum could have a material adverse effect on our results of operations and cash flows. Fluctuations in working capital are influenced by shipments, the LME and Midwest price of primary aluminum, cost of electricity and materials, and by the timing of cash receipts from major customers and disbursements to our suppliers.

Our operating results vary significantly with changes in the price of primary aluminum and the raw materials used in its production, including electrical power, alumina, aluminum fluoride, calcined petroleum coke, pitch, finished carbon anodes and cathodes. Because we sell our products based principally on the LME price for primary aluminum, we cannot pass on increased costs to our customers. Although we attempt to mitigate the effects of price fluctuations through the use of various fixed-price commitments, financial instruments and by pricing some of our raw materials and energy contracts based on LME prices, these efforts also limit our ability to take advantage of favorable changes in the market prices for primary aluminum or raw materials and may affect our financial position, results of operations and cash flows.
Electricity represents our single largest operating cost. As a result, the availability of electricity at competitive prices is critical to the profitability of our operations. Portions of the contracted cost of the electricity supplied to Mt. Holly and all of Hawesville’s electricity costs vary with the supplier’s costs. An increase in these costs would increase the price these facilities pay for electricity. Costs under the Mt. Holly and Hawesville electricity contracts have substantially increased in recent years, due in part to rising fuel prices. As these contracts have take-or-pay type provisions, the financial position, results of operations and cash flows of Hawesville and Mt. Holly may be affected by the price for electric power even if we curtailed production capacity at these facilities.
We expect that future electric power costs in the U.S. will present severe challenges to our domestic smelting operations. Recently proposed environmental rules affecting coal-fired power plants are expected to have a disproportionate impact on the electrical power providers for our smelting operations in Kentucky, South Carolina and West Virginia. Under the rules proposed by the Environmental Protection Agency (the “EPA”) new limits on the emission on mercury, sulfur dioxide and other toxic air pollutants would require existing power plants to make significant capital investments in order to comply with the new standards. We expect that these new rules will result in power providers shutting down a significant portion of their coal-fired power generation capacity. The power generating facilities that remain open will incur substantial compliance costs. The reduced power generation capacity and the additional compliance costs are forecasted to put upward pricing pressure for electrical power, particularly in areas with high concentrations of coal-fired power generation facilities like Kentucky and West Virginia.
The average LME price for primary aluminum for 2011 rose to $2,398 per metric ton; however, prices declined to approximately $2,000 by year end. The average LME price in 2011 was up significantly from $2,173 per metric ton in 2010 and was $1,665 per metric ton in 2009. Demand for aluminum products continued to improve in 2011 with strong growth in Asia and some improvement in developed markets. Commodity prices for other metals (copper in particular) remained relatively high in 2011, resulting in a pricing relationship between these metals and primary aluminum that was inconsistent with historic trends. If current pricing trends continue, there may be some modest additional demand for primary aluminum products from substitution for these higher priced metals.
During the first half of 2011, higher LME prices provided an incentive to producers to restart idled capacity worldwide. However, with lower LME prices in the second half of 2011, no new restarts were announced outside of China and several capacity closures in Europe and Australia were announced in early 2012. Industry analysts have forecasted that the aluminum market will have surplus production in the near future which may exert downward pressure on LME prices for primary aluminum; however, global cost pressures for aluminum producers are expected to provide some support for metal prices as a significant portion of aluminum producers were producing at a cost above the metal price at year end 2011.

Current primary aluminum warehouse inventories remain at or near historically high levels. Traditionally, high inventory levels tend to exert downward pressure on the LME price for primary aluminum; however this relationship is contrary to what we have observed in recent history. In addition, high warehouse inventory levels would also traditionally cause weakened premiums, but premiums in 2011 remained at or near multi-year highs in the U.S and Europe. It is not possible to predict how long these conditions will continue, but unless there is discipline from suppliers in curtailing uneconomic production as well as improving conditions for metal demand, we may experience lower LME prices for primary aluminum and lower premiums.
Recent Developments
Century appoints Michael Bless as President and Chief Executive Officer
In February 2012, we announced that our Board of Directors had appointed Michael Bless President and Chief Executive Officer of Century. Mr. Bless, who was named Acting President and CEO in November 2011, had previously served as Century's Executive Vice President and Chief Financial Officer since January 2006.
Mr. Bless succeeded Logan Kruger, who terminated his employment with Century and resigned as a member of the Board of Directors. Mr. Kruger has also brought a lawsuit against Century alleging a breach of contract and wrongful termination. We believe these claims are without merit and we intend to vigorously defend against them. See Item 3 “Legal Proceedings” and Note 15 Commitments and contingencies in the consolidated financial statements included herein.
Nordural Helguvik receives favorable results in power arbitration
In December 2011, Nordural Helguvik hf received the results of its arbitration with HS Orka hf, one of the power suppliers to its Helguvik greenfield project. The arbitration panel ruled that the parties' power contract remains in force in accordance with its terms and that HS Orka remains obligated to provide the full amount of contracted power to Nordural, subject to the satisfaction of certain remaining conditions. We are currently in discussions with HS Orka with respect to the satisfaction of these conditions.
Grundartangi labor contract wage negotiations completed
In September 2011, we reached an agreement on the revised wage terms under our existing labor agreement with the five labor unions representing approximately 84% of workers at Grundartangi. The wage and other terms of the labor agreement expire on December 31, 2014.
Stock Repurchase Program
In August 2011, our Board of Directors approved a $60 million stock repurchase program. From August 11, 2011 through December 31, 2011, we repurchased 4,386,521 shares of common stock at an aggregate purchase price of $45.9 million. We had $14.1 million remaining under the repurchase program authorization as of December 31, 2011. See Item 5 Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities for additional information about the program.
Century names new Vice President – North America Operations
In August 2011, we announced that John Hoerner was named Vice President - North America Operations, effective September 1, 2011. Mr. Hoerner comes to Century from RUSAL, where he most recently served as Managing Director of Kubikenborg Aluminium in Sundsvall, Sweden (Kubal) as well as General Director of Finished Production for the Western Division of RUSAL.

Restart and production inefficiencies impact our U.S. primary aluminum output
Our U.S. primary aluminum production for 2011 was negatively affected by Hawesville's slower than anticipated return to full stable operations following the restart of its curtailed potline earlier this year. In addition, the plant experienced reduced production efficiencies and higher costs related to the unstable conditions which prevailed during the majority of the year. Though the plant has essentially returned to full production, we currently expect that Hawesville will return to full stable operations in the first quarter of 2012.
1.75% Notes redemption
In May 2011, we redeemed all of the issued and outstanding 1.75% Notes in accordance with their terms. The 1.75% Notes were redeemed at 100% of their principal amount plus accrued and unpaid interest. The redemption of the 1.75% Notes was funded with the available cash on hand.
Stockholder class actions dismissed and appealed
In March 2011, the purported stockholder class actions pending against us consolidated as Century Aluminum Company Securities Litigation were dismissed with prejudice by the U.S. District Court for the Northern District of California. In March 2011, plaintiffs filed a notice of appeal.
Pension and benefit plan contributions
During 2011, we made contributions of approximately $17.7 million to the qualified defined benefit plans we sponsor. In addition, at the time three directors designated for nomination to our Board of Directors were elected, it was determined a “change of control” occurred under the terms of the non-qualified SERB. As a result, we were required to make a $16.7 million contribution to a Rabbi trust to fully fund the non-qualified SERB benefit obligation. Our qualified defined benefit plan and non-qualified SERB contributions were $34.4 million during the year. In addition, we provided $2.1 million in funding for defined benefit plans at the Mt. Holly facility.
Results of Operations
The following discussion reflects our historical results of operations, the comparability of which is affected by the following unusual or infrequent events:

| · | the restart of operations of one potline at Hawesville in April 2011;
| · | the curtailments of operations of Ravenswood’s remaining three potlines and one potline at Hawesville in February 2009 and March 2009, respectively; and,
| · | the transfer of our 50% ownership positions in Gramercy and St. Ann to Noranda on September 1, 2009.

Accordingly, the results for fiscal years 2010 and 2009 are not fully comparable to the results of operations for fiscal year 2011. We believe that our historical results are not indicative of our current business. You should read the following discussion in conjunction with our consolidated financial statements included herein.

Year Ended December 31, 2011 Compared to Year Ended December 31, 2010
Net sales: Net sales for the year ended December 31, 2011 increased $187.1 million to $1,356.4 million. Higher price realizations for primary aluminum in the year ended December 31, 2011, contributed $148.9 million to the sales increase. The monthly average LME cash price for 2011 was up 6% from the monthly average LME cash price in 2010. Higher net sales volume positively impacted the year over year sales increase by $38.2 million. Direct shipments increased 16,949 metric tons from the same period in 2010 due to the restart of curtailed capacity at Hawesville and the increase in direct sales from Grundartangi. Toll shipments declined 202 metric tons from the same period in 2010.
Gross profit (loss): During 2011, higher price realizations, net of LME based alumina and power cost increases, increased gross profit by $97.3 million. Higher shipment volume contributed $2.4 million to the increase in gross profit. Offsetting these increases were $102.4 million in net cost increases comprised of: increased costs for power at our U.S. smelters, $18.0 million; increased costs for maintenance, supplies and materials, $82.2 million; other cost increases, $3.4 million; and lower depreciation charges, $1.2 million.
Of the $82.2 million in increased costs for maintenance, supplies and materials, 70% of the increase relates to the cost of carbon and bath products required to produce aluminum. A significant portion of the remaining cost increases relates to the restart of a potline at Hawesville, inefficiencies and instabilities experienced during and, subsequent to, the restart and resultant under-absorption of costs.
A decline in LME prices at the end of 2011 resulted in a decline in the market value of our inventory below its cost basis, resulting in charges to cost of goods sold of $19.8 million in 2011. We recorded a favorable net inventory adjustment of $0.4 million in 2010. On a year to year comparative basis, this negatively impacted the change in gross profit by an additional $20.2 million.
Other operating income – net: Other operating income is primarily related to items associated with Ravenswood. In addition to the on-going costs at the curtailed facility, in 2011 and 2010, we recorded credits of $18.3 million and $56.7 million, respectively, due to the elimination of medical benefits for retirees of Ravenswood. In addition, we recorded a charge of $1.1 million in 2011 for pension benefits that will be payable to a group of employees whose combination of age, years of service and lay-off status make them eligible for accelerated pension benefits in 2012. We recorded a charge of $4.6 million in 2010 for pension benefits that will be payable to a group of employees whose combination of age, years of service and lay-off status made them eligible for accelerated pension benefits in 2011.
Selling general and administrative expenses: During 2011, outside professional support, employee-related expenses and administrative spending to support the Helguvik project were lower than those recorded in 2010. Off-setting these cost improvements in 2011 were charges of $7.7 million in the second quarter related to the accelerated vesting of share-based compensation plans arising from changes in the Company’s Board of Directors and serverance accruals for changes in the executive management team.
Net gain (loss) on forward contracts: The net gain (loss) on forward contracts in 2011 and 2010 relates primarily to marking-to-market options that were put in place to provide partial downside price protection for our domestic facilities. At the end of 2011, the unexpired put options increased in value due to declining LME prices for primary aluminum. At the end of 2010, the unexpired put options decreased in value due to rising LME prices for primary aluminum. Changes in the value of unexpired put options, along with the write-off of expired contracts in both 2011 and 2010, resulted in a year over year improvement of $11.3 million in this category.
Tax provision: Our 2011 and 2010 income tax expense is related to our net income in Iceland with a partial offset to expense due to a discrete tax benefit arising from the elimination of medical benefits for retirees at Ravenswood.

Equity in earnings (losses) of joint ventures: The amounts reported in both years primarily reflect the results of Century’s joint venture, BHH.
Year Ended December 31, 2010 Compared to Year Ended December 31, 2009
Net sales: Net sales for the year ended December 31, 2010 increased $270.0 million to $1,169.3 million. Higher price realizations for primary aluminum in the year ended December 31, 2010, contributed $296.7 million to the sales increase. The monthly average LME cash price for 2010 was up 31% from the monthly average LME cash price in 2009. Lower net sales volume negatively impacted the year over year sales increase by $26.7 million. Direct shipments declined 11,387 metric tons from the same period in 2009 due to capacity curtailments in the U.S. that occurred during the first quarter of 2009. Toll shipments declined 8,344 metric tons from the same period in 2009. The decline in toll shipments from Grundartangi was due in part to a transformer outage that reduced overall metal production and also due to selling aluminum on a direct basis in 2010. Grundartangi’s direct shipments were 6,196 metric tons in 2010.
Gross profit (loss): During 2010, higher price realizations, net of LME based alumina cost and LME-based power cost increases, increased gross profit by $254.8 million. Lower shipment volume, due to capacity curtailments, contributed $9.2 million to the increase in gross profit. Offsetting these increases were $52.7 million in net cost increases comprised of: increased costs for power at our U.S. smelters, $28.5 million (primarily attributable to our new power contract at Hawesville); increased costs for maintenance, supplies and materials, $7.9 million; other cost increases, $25.6 million; and offset by reduced net amortization and depreciation charges, primarily at Hawesville, $9.3 million.
Due to the turnover of inventory during 2009 and increased market prices as of December 31, 2009, the previously recognized lower of cost or market inventory reserve was adjusted to reflect the lower of cost or market value of our December 31, 2009 ending inventory. These adjustments favorably impacted gross profit by $33.6 million during 2009. We recorded a favorable lower of cost or market adjustment of $0.4 million in 2010. On a year to year comparative basis, this negatively impacted the change in gross profit by an additional $33.2 million.
Other operating income – net: During 2010, we recorded credits of $56.7 million due to the elimination of medical benefits for retirees of the Ravenswood facility. We recorded a charge of $4.6 million for pension benefits that will be payable to a group of employees whose combination of age, years of service and lay-off status make them eligible for accelerated pension benefits in 2011. Ongoing site costs, severance and related employee costs at the Ravenswood facility account for the remaining $14.7 million of charges in this category.
During 2009, the expenses associated with the curtailed potlines at our Ravenswood and Hawesville facilities were $41.7 million. This amount includes expenses incurred to curtail operations and to maintain the Ravenswood facility in a curtailed state. See Note 3 Curtailment of Operations – Ravenswood and Hawesville in consolidated financial statements included herein.
During 2009, we recorded a gain of $81.6 million related to our agreement with E.ON that was consummated concurrently with the new long term power contract for Hawesville. In addition, we wrote off the remaining carrying value of the intangible asset associated with the previous power contract that was terminated July 16, 2009. The amount of the write-off was $23.8 million. See Note 2 Long-term power contract for Hawesville in consolidated financial statements included herein for additional information about this contract.
Selling general and administrative expenses: The decrease in selling, general and administrative expenses in 2010 is due to a reduction in employee costs and outside professional support, partially offset by increased general and administrative costs to support the Helguvik project.
- 37 -

Table of Contents
Interest expense – third party: The decrease in interest expense in 2010 from 2009 is the result of the exchange of our convertible debt for equity in 2009, partially offset by increased interest expense due to the exchange of 8.0% Notes for 7.5% Notes in the fourth quarter of 2009 and the first quarter of 2010.
Net loss on forward contracts: The net gain (loss) on forward contracts of $10.5 million for the year ended December 31, 2010 relates to marking-to-market options that were put into place to provide partial downside price protection for our Hawesville facility.
For the year ended December 31, 2009, the net gain (loss) on forward contracts was $19.4 million. Over half of the net loss reported for the year ended December 31, 2009 relates to marking-to-market options that were put in place to provide partial downside price protection for our Hawesville facility. The remainder of the loss relates to the discontinuation of cash flow hedge accounting treatment for our natural gas financial forward contracts associated with our investment in Gramercy, recognition of previously settled Icelandic krona hedges associated with the Helguvik project and losses on derivatives associated with the Hawesville and Ravenswood power contracts.
Tax provision: Our 2010 income tax expense is related to our net income in Iceland with a partial offset to expense due to a discrete tax benefit arising from the elimination of medical benefits for retirees of the Ravenswood facility. Our 2009 tax provision benefited from the release of income tax reserves for uncertain tax positions due to statute of limitations expiration and additional NOL carry back claims due to a recently enacted U.S. tax law offset by increased Iceland tax rates.
Equity in earnings (losses) of joint ventures: The results in 2010 reflect the results of Century’s joint ventures, primarily BHH. In August 2009, we signed an agreement to transfer our ownership interests in Gramercy and St. Ann to our joint venture partner, Noranda resulting in a loss on disposition of $73.2 million in 2009.
Liquidity and Capital Resources
Our principal sources of liquidity are available cash, cash flow from operations and available borrowings under our revolving credit facility. We have also raised capital in the past through the public equity and debt markets. We continuously explore various other financing alternatives. Our principal uses of cash are the funding of operating costs (including postemployment benefits), maintenance of curtailed production facilities, payments of principal and interest on our outstanding debt, the funding of capital expenditures, investments in our growth activities and in related businesses, repurchases of common stock, working capital and other general corporate requirements.
Our consolidated cash and cash equivalents balance at December 31, 2011 was approximately $183 million compared to $304 million at December 31, 2010. Century's revolving credit facility matures in July 2014. As of December 31, 2011, our credit facility had no loan amounts outstanding and approximately $58 million of net availability. We have approximately $41 million of letters of credit outstanding under our credit facility, which allowed us to eliminate our restricted cash deposits. Future curtailments of domestic production capacity would reduce domestic accounts receivable and inventory, which comprise the borrowing base of our credit facility, and would result in a corresponding reduction in availability under the credit facility.
Domestic primary aluminum production for 2011 was negatively affected, primarily due to Hawesville's slower than anticipated return to full stable operations following the restart of its curtailed potline earlier this year. We expect that our cash flow from operations will continue to be negatively impacted by these inefficiencies through the first quarter of 2012.

In August 2011, our Board of Directors approved a $60 million stock repurchase program. Under the program, we may repurchase up to $60 million of our outstanding shares of common stock from time to time on the open market at prevailing market prices, in block trades or otherwise. Through December 31, 2011, we have expended $45.9 million under the repurchase program. We have $14.1 million remaining under the repurchase program authorization. The repurchase program may be suspended or discontinued at any time.
In May 2011, we used $47.1 million of available cash on hand to redeem all of our outstanding 1.75% Notes at 100% of their principal amount plus accrued and unpaid interest to May 19, 2011. We have $249.6 million in 8.0% senior secured notes payable that will mature on May 15, 2014. We may be required to make installment payments for the E.ON contingent obligation. These payments are contingent based on the LME price of primary aluminum and the level of Hawesville’s operations. Based on the LME forward market at December 31, 2011 and management’s estimate, we do not expect to make any payments for the E.ON contingent obligation until 2018.
During 2011, we made contributions to the qualified defined benefit plans we sponsor of approximately $17.7 million and $16.7 million in contributions to a Rabbi trust to fund the non-qualified SERB benefit obligation. In addition, we provided $2.1 million in funding for defined benefit plans at the Mt. Holly facility. We may choose to make additional contributions to these plans from time to time at our discretion. Based on current actuarial and other assumptions, we expect to make additional contributions to these plans of approximately $9 million during 2012.
Effective January 1, 2011, CAWV no longer provided retiree medical benefits to active salaried CAWV personnel or any other personnel who retired prior to November 1, 2010. CAWV has made no commitments as to the future status of retiree medical benefits for hourly personnel who are currently covered by an active medical program. We expect these plan amendments will significantly reduce our future cash payments for postretirement medical benefits. See Note 11 Pension and Other Postretirement Benefits in the consolidated financial statements included herein for additional information about the Ravenswood retiree medical benefit changes.
In addition, with the ratification of the Hawesville labor agreement, changes were made to the retiree medical benefits program for employees who retire during the term of the labor agreement. We expect these changes to the Hawesville labor agreement will significantly reduce our future cash payments for postretirement medical benefits. See Note 11 Pension and Other Postretirement Benefits in the consolidated financial statements included herein for additional information about the Hawesville retiree medical benefit changes.
In June 2011, the Pension Benefit Guaranty Corporation (the “PBGC”) informed us that it believed that a “cessation of operations” under the Employee Retirement Income Security Act of 1974 (“ERISA”) had occurred at our Ravenswood facility as a result of the curtailment of operations at the facility and requested that we engage in discussions with the PBGC relating thereto. We have notified the PBGC that we do not believe that a “cessation of operations” has occurred and have entered into ongoing discussions with the PBGC to resolve the matter. If a “cessation of operations” is ultimately determined to have occurred under ERISA, it may be necessary for Century Aluminum of West Virginia to accelerate the timing of additional contributions to certain of its defined pension plans or post other collateral with the PBGC or negotiate an alternative agreement.
Under an agreement with the Government of Iceland, Nordural Grundartangi ehf agreed to prepay taxes during 2012, 2011 and 2010 as an advance levy of income taxes and other governmental taxes for the period of 2013 through 2018. The amount of prepaid taxes paid through December 31, 2011 was approximately $ 6.3 million and we expect to prepay an additional $3.2 million in 2012. The prepaid taxes will offset taxes otherwise payable in equal installments over the period 2013 through 2018.

We received a $26.9 million withholding tax refund in Iceland in the fourth quarter of 2011 for taxes paid for intercompany dividend payments in February 2011. We paid an additional $20 million in withholding tax for intercompany dividend payments in Iceland in 2011 and expect to pay an additional $10 million in the first quarter of 2012. We expect to receive a withholding tax refund in the fourth quarter of 2012 related to intercompany dividend payments. The withholding taxes and associated refunds are payable in Icelandic krona (“ISK”) and we are subject to foreign currency risk associated with fluctuations in the value of the U.S. dollar as compared the ISK.We do not expect to receive any material domestic tax refunds in the near future.
Capital Resources
We intend to finance our future recurring capital expenditures from available cash and our cash flow from operations. For major investment projects, such as the Helguvik project, we would seek financing from various capital and loan markets and may potentially pursue the formation of strategic alliances. We may be unable to issue additional debt or equity securities, or to issue these securities on attractive terms, due to a number of factors including a lack of demand, unfavorable pricing, poor economic conditions, unfavorable interest rates, or our financial condition or credit rating at the time. Future uncertainty in the U.S. and international markets and economies may adversely affect our liquidity, our ability to access the capital markets and our financial condition.
Capital expenditures for 2011 were $33.0 million, $12.9 million of which was related to the Helguvik project, with the balance principally related to upgrading production equipment, improving facilities and complying with environmental requirements. We believe capital spending in 2012, excluding the activity on the Helguvik project, will be approximately $25 to 30 million.
We have made and continue to make capital expenditures for the construction and development of our Helguvik project. We have substantial future contractual commitments for the Helguvik project. If we were to cancel the Helguvik project, we would expect to incur an additional $20 million in contract cancellation costs. We are continuing to negotiate with the power suppliers to the project to remove all the remaining conditions to their obligations to supply contracted power. The timing of the power availability together with other factors, including financing, will determine when we will resume major construction activity at Helguvik. We expect that the portion of capital expenditures for this project that we will fund from our existing cash and operating cash flow will be approximately $1 million per month until the restart of major construction activities. We cannot, at this time, predict when the restart of major construction activity will occur. See Item 1A, “Risk Factors — Construction at our Helguvik smelter site is under review. Substantial delay in the completion of this project may increase its cost and impose other risks to completion that are not foreseeable at this time.” included herein.
Historical
Our Consolidated Statements of Cash Flows for the years ended December 31, 2011, 2010 and 2009 are summarized below:

|  | 2011 |  |  | 2010 |  |  | 2009 |
|  | (dollars in thousands) |
Net cash provided by (used in) operating activities |  | $ | (2,936 | ) |  | $ | 131,510 |  |  | $ | 39,399 |
Net cash used in investing activities |  |  | (24,895 | ) |  |  | (25,471 | ) |  |  | (46,213 | )
Net cash provided by (used in) financing activities |  |  | (93,064 | ) |  |  | 23 |  |  |  | 75,648 |
Net change in cash and cash equivalents |  | $ | (120,895 | ) |  | $ | 106,062 |  |  | $ | 68,834 |

Table of Contents
Net cash used in operating activities in 2011 was $2.9 million compared to cash provided by operating activities of $131.5 million in 2010. The decrease in cash from operations in 2011 was primarily due to withholding tax payments in Iceland, pension and benefit contributions, an increase in working capital associated with the restart of Hawesville and the reduction of the benefits received for the E.ON contractual receivable in 2011 (the E.ON contractual receivable expired in 2010).
Net cash provided by operating activities in 2009 was $39.4 million. Our net cash from operations was due to tax refunds partially offset by operating losses and costs of curtailed operations in 2009.
Our net cash used in investing activities in 2011 was $24.9 million compared to $25.5 million in 2010. The decrease in cash used was primarily due to reduced restricted cash requirements and a payment received on advances to joint ventures.
Net cash used in investing activities for 2010 was $25.5 million compared to $46.2 million in 2009. The decrease was due to restricted cash being released as a result of our replacing cash collateral with letters of credit under our new revolving line of credit in 2010. In addition, a portion of the decrease was due to lower investments in capital expenditures to maintain and improve plant operations and reduced spending on the Helguvik project.
Our net cash used in financing activities during 2011 was $93.1 million. The use was primarily due to the redemption of the 1.75% Notes in May 2011 of $47.1 million and $45.9 million for the repurchase of common stock.
Net cash provided by financing activities during 2010 was $23 thousand from the net proceeds from the issuance of common stock from the exercise of stock options.
Net cash provided by financing activities during 2009 was $75.6 million. We received $103.1 million in net proceeds from the issuance of common stock from our equity offering in February 2009. We had repayments of $25.0 million on our revolving line of credit and paid financing fees of $2.4 million.

| Critical Accounting Estimates

Our significant accounting policies are described in Note 1 of the consolidated financial statements. The preparation of the financial statements requires that management make judgments, assumptions and estimates in applying these accounting policies. Those judgments are normally based on knowledge and experience about past and current events and on assumptions about future events. Critical accounting estimates require management to make assumptions about matters that are highly uncertain at the time of the estimate and a change in these estimates may have a material impact on our financial position or results of operations. Significant judgments and estimates made by our management include expenses and liabilities related to pensions and other postemployment benefits, deferred tax assets and property, plant and equipment. Our management has discussed the development and selection of these critical accounting estimates with the audit committee of our board of directors and the audit committee has reviewed our disclosure.
Pension and Other Postemployment Benefit Liabilities
We sponsor several pension and other postemployment benefit plans. Our liabilities under these defined benefit plans are determined using methodologies that involve several actuarial assumptions, the most significant of which are the discount rate, health care inflation rate and the long-term rate of return on plan assets.
- 41 -

Table of Contents
Discount Rate Selection
It is our policy to select a discount rate for purposes of measuring obligations under defined benefit plans by matching cash flows separately for each plan to yields on zero coupon bonds. We use the Citigroup Pension Liability Index for determining these yields.
The Citigroup Pension Liability Index was specifically developed to meet the criteria set forth in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 715. The published information at the end of each calendar month includes spot rate yields (zero coupon bond yield estimates) in half year increments for use in tailoring a discount rate to a particular plan's projected benefit cash flows. The Citigroup Pension Liability Index rate represents the discount rate developed from these spot rate yields, based on the pattern and duration of the benefit payments of a typical, large, somewhat mature pension plan.
The individual characteristics of each plan, including projected cash flow patterns and payment durations, have been taken into account, since discount rates are determined on a plan-by-plan basis. We will generally select a discount rate rounded to the nearest 0.25%, unless specific circumstances provide for a more appropriate non-rounded rate to be used. We believe the projected cash flows used to determine the Citigroup Pension Liability Index rate provide a good approximation of the timing and amounts of our defined benefits payments under our plans and no adjustment to the Citigroup Pension Liability Index rate has been made.
Therefore, as of December 31, 2011, we selected a weighted-average discount rate of 4.25% for all our pension plans and a weighted-average discount rate of 4.25% for our other postemployment benefit plans.
A change of a half percentage point in the discount rate for our defined benefit plans would have the following effects on our obligations under these plans in 2011:

Effect of changes in the discount rates on the Projected Benefit Obligations for: |  | 50 basis point increase |  |  | 50 basis point decrease |
|  | (dollars in millions) |
Pension plans |  | $ | (10.7 | ) |  | $ | 11.9 |
Other postemployment benefit (“OPEB”) plans |  |  | (8.8 | ) |  |  | 9.8 |

Century provides postemployment benefit plans that provide health care and life insurance benefits for a portion of the retired employees of our U.S. based operations. ASC 715 requires the accrual of the estimated cost of providing postretirement benefits during the working careers of those employees who could become eligible for such benefits when they retire. We fund these benefits as the retirees submit claims.
Measurement of our postretirement benefit obligations requires the use of several assumptions about factors that will affect the amount and timing of future benefit payments. The assumed health care cost trend rates are the most critical estimates for measurement of the postretirement benefits obligation. Changes in the health care cost trend rates have a significant effect on the amounts reported for the health care benefit obligations.

Table of Contents
Century assumes medical inflation is initially 10%, declining to 5% over six years and thereafter. A one-percentage-point change in the assumed health care cost trend rates would have the following effects in 2011:

|  | 1% Increase |  |  | 1% Decrease |
|  | (dollars in millions) |
Effect on total of service and interest cost components |  | $ | 1.2 |  |  | $ | (1.0 | )
Effect on accumulated postretirement benefit obligation |  |  | 21.1 |  |  |  | (17.3 | )

Long-term Rate of Return on Plan assets assumption
We are currently using an 8.0% long-term rate of return on plan assets for the development of the net periodic cost for the defined benefit pension plans. The rate was selected by taking into account our expected asset mix and is based on historical performance as well as expected future rates of return on plan assets.
Deferred Income Tax Assets
We regularly assess the likelihood that deferred tax assets will be recovered from future taxable income. To the extent we believe that it is more likely than not that a deferred tax asset will or may not be realized, a valuation allowance is established. When a valuation allowance is established or increased, an income tax charge is included in the consolidated financial statements and net deferred tax assets are adjusted accordingly. Changes in the tax laws, statutory tax rates and future taxable income levels could result in actual realization of the deferred tax assets being materially different from the amounts provided for in the consolidated financial statements. If the actual recovery amount of the deferred tax asset is less than anticipated, we would be required to write-off the remaining deferred tax asset and increase the tax provision.
The amount of a valuation allowance is based upon our best estimate of our ability to realize the net deferred tax assets. A valuation allowance can subsequently be reversed when we believe that the assets are realizable on a more likely than not basis. We have a valuation allowance of $774 million against all of our U.S. deferred tax assets and a portion of our Icelandic deferred tax assets as of December 31, 2011, due to our assessment that it is more likely than not that these assets will not be realized based on our cumulative net losses and future market conditions.
Property, Plant and Equipment Impairment
We review our property, plant and equipment whenever events or circumstances indicate that the carrying amount of these assets (asset group) may not be recoverable. The carrying amount of the assets (asset group) is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset (asset group). In that case, an impairment loss would be recognized for the amount the carrying amount exceeds the fair value of the assets (asset group), with the fair value determined using a discounted cash flow calculation. These estimates of future cash flows include management’s assumptions about the expected use of the asset (asset group), the remaining useful life, expenditures to maintain its service potential, market and cost assumptions.
Determination as to whether and how much an asset is impaired involves significant management judgment involving highly uncertain matters, including estimating the future success of product lines, future sales volumes, future selling prices and cost, alternative uses for the assets, and estimated proceeds from the disposal of the assets. However, the impairment reviews and calculations are based on estimates and assumptions that take into account our business plans and long-term investment decisions at the time of such impairment reviews.

We are currently evaluating the Helguvik project’s cost, scope and schedule, in light of issues surrounding the Helguvik electrical power agreements. In December 2011, Nordural Helguvik received the results of its arbitration with HS, one of the power suppliers to the Helguvik project. The arbitration panel ruled that the parties' power contract remains in force in accordance with its terms and that HS remains obligated to provide the full amount of contracted power to Nordural Helguvik, subject to the satisfaction of certain remaining conditions. We are currently in discussions with both power suppliers with respect to the satisfaction of all remaining conditions. If we are unable to reach agreement with HS and OR regarding the satisfaction of the remaining conditions to their respective power contracts, we may have to seek alternative sources of power, incur substantially increased power costs or further curtail construction activities of the Helguvik project. Due to the limited number of Icelandic power providers with resources sufficient to provide power to the Helguvik project (only three are currently in operation in Iceland), we may find it difficult or impossible to procure additional sources of power if HS and/or OR do not perform under their existing agreements and may be unable to complete construction of the smelter. If we agree to pay increased prices for power or substantially delay or be unable to complete the Helguvik project, we may have to recognize a substantial loss on our investment.
The aggregate capital expenditures through December 31, 2011 related to the Helguvik project were approximately $138 million. In evaluating the construction in progress at Helguvik, we considered the costs to complete the construction and the estimated undiscounted future cash flows over the estimated useful life of Helguvik and concluded that the estimated undiscounted future cash flows should exceed the expected cost of constructing the Helguvik project. If we do not restart construction, we may have to recognize a loss on our investment at the time that a decision was made to abandon the project.
In February 2009, we curtailed the operations of the Ravenswood facility. The net carrying value of the asset group at the Ravenswood facility was approximately $61 million at December 31, 2011. If the estimated future undiscounted cash flows from the asset group were less than the carrying value of the asset group or our assumptions for the use of this facility were to change, we would recognize a loss on all or a portion of the assets at the time. The estimated future undiscounted cash flows assume that the operations at the Ravenswood facility will resume once LME prices for primary aluminum are sustained and upon the successful negotiation and execution of certain critical enabling agreements for power and labor.

| Environmental Expenditures

We have incurred and in the future will continue to incur capital expenditures and operating expenses for matters relating to environmental control, remediation, monitoring and compliance.
The aggregate environmental related accrued liabilities were $0.8 million and $0.8 million at December 31, 2011 and 2010, respectively. We believe that compliance with current environmental laws and regulations (U.S. and foreign) is not likely to have a material adverse effect on our financial condition, results of operations or liquidity; however, environmental laws and regulations may change, and we may become subject to more stringent environmental laws and regulations in the future.
We expect to incur operating expenses relating to environmental matters of $11 to $12 million in 2012. These amounts do not include any projected capital expenditures or operating expenses for our joint ventures. See Note 15 Commitments and contingencies to the consolidated financial statements included herein.

| Other Contingencies

We are a defendant in several actions relating to various aspects of our business. While it is impossible to predict the ultimate disposition of any litigation, we do not believe that any of these lawsuits, either individually or in the aggregate, will have a material adverse effect on our financial condition, results of operations or liquidity. See Item 3, “Legal Proceedings” and Note 15 Commitments and contingencies to the consolidated financial statements included herein for additional information.

Contractual Obligations
In the normal course of business, we have entered into various contractual obligations that will be settled in cash. These obligations consist primarily of long-term debt obligations and purchase obligations. The expected future cash flows required to meet these obligations are shown in the table below. More information is available about these contractual obligations in the notes to the consolidated financial statements included herein.

|  | Payments Due by Period |
|  | Total |  |  | 2012 |  |  | 2013 |  |  | 2014 |  |  | 2015 |  |  | 2016 |  |  | Thereafter |
|  | (dollars in millions) |
Long-term debt (1) |  | $ | 273 |  |  | $ | — |  |  | $ | — |  |  | $ | 252 |  |  | $ | — |  |  | $ | — |  |  | $ | 21 |

Purchase obligations (3) |  |  | 2,869 |  |  |  | 517 |  |  |  | 443 |  |  |  | 468 |  |  |  | 124 |  |  |  | 124 |  |  |  | 1,193 |
OPEB obligations (4) |  |  | 70 |  |  |  | 6 |  |  |  | 5 |  |  |  | 6 |  |  |  | 7 |  |  |  | 7 |  |  |  | 39 |
Other liabilities (5) |  |  | 154 |  |  |  | 41 |  |  |  | 41 |  |  |  | 41 |  |  |  | 3 |  |  |  | 3 |  |  |  | 25 |

(1) | Long-term debt includes principal repayments on the 7.5% Notes, the 8.0% Notes, the IRBs and the E.ON contingent obligation. Payments are based on the assumption that all outstanding debt instruments will remain outstanding until their respective due dates. We assume that the E.ON contingent obligation will be repaid when the LME contingency is met using the LME forward curve as of December 31, 2011.
(2) | Estimated interest payments on our long-term debt are based on several assumptions, including an assumption that all outstanding debt instruments will remain outstanding until their respective due dates. Our estimated future interest payments for any debt with a variable rate are based on the assumption that the December 31, 2011 rate for that debt continues until the respective due date. We assume that interest payments due on the E.ON contingent obligation will be paid when the LME contingency is met using the LME forward curve as of December 31, 2011.
(3) | Purchase obligations include long-term alumina, power contracts and anode contracts. Our CAKY power contract contains a 12 month cancellation clause and allows us to receive credits for unused power that Big Rivers is able to sell to other parties. We assumed that during the contract period, CAKY would achieve and maintain full production levels and no credits for unused power would be received. For contracts with LME-based pricing provisions, including our long-term alumina contracts and Nordural’s power contracts, we assumed an LME price using the LME forward curve as of December 31, 2011.
(4) | Includes the estimated benefit payments for our OPEB obligations through 2021, which are unfunded.
(5) | Other liabilities include SERB benefit payments, workers' compensation benefit payments, asset retirement obligations and contractual commitments for the Helguvik project. Asset retirement obligations are estimated disposal costs for the potliner currently in service. Our contractual commitments for the Helguvik projects consist of various contracts for equipment and services associated with the project.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

| Commodity Price Sensitivity

We are exposed to price risk for primary aluminum. We manage our exposure to fluctuations in the price of primary aluminum through financial instruments to protect our downside price risk exposure for our domestic production. In addition, we manage our exposure to fluctuations in our costs by purchasing certain of our alumina and power requirements under supply contracts with prices tied to the same indices as our aluminum sales contracts (the LME price of primary aluminum). Our risk management activities do not include any trading or speculative transactions.
Forward Physical Delivery Agreements
Primary Aluminum Sales Contracts

Contract | Customer | Volume | Term | Pricing
Glencore Metal Agreement (1) | Glencore | 20,400 mtpy | Through December 31, 2013 | Variable, based on U.S. Midwest market
Glencore Sweep Agreement (2) | Glencore | Surplus primary aluminum produced in the United States | Through December 31, 2012 | Variable, based on U.S. Midwest market
Glencore Nordural Metal Agreement | Glencore | Approximately 16,000 metric tons | Through December 31, 2012 | Variable, based on LME
Southwire Metal Agreement (3) | Southwire | 220 to 240 million pounds per year (high conductivity molten aluminum) | Through December 31, 2013 | Variable, based on U.S. Midwest market

(1) | We account for the Glencore Metal Agreement as a derivative instrument under ASC 815. Under the Glencore Metal Agreement, pricing is based on then-current Midwest market prices, adjusted by a negotiated U.S. Midwest premium with a cap and a floor as applied to the current U.S. Midwest premium.
(2) | The Glencore Sweep Agreement is for all metal produced in the U.S. in 2012, less existing sales agreements and high-purity metal sales. The term of the contract may be extended for one year upon mutual agreement.
(3) | The Southwire Metal Agreement contract contains termination rights in the event of a partial or full curtailment of the Hawesville facility.

Long-term Tolling Contracts

Contract | Customer | Volume | Term | Pricing
Billiton Tolling Agreement (1) | BHP Billiton | 130,000 mtpy | Through December 31, 2013 | LME-based
Glencore Toll Agreement (1) | Glencore | 90,000 mtpy | Through July 31, 2016 | LME-based
Glencore Toll Agreement (1) | Glencore | 40,000 mtpy | Through December 31, 2014 | LME-based

(1) | Grundartangi’s tolling revenues include a premium based on the EU import duty for primary aluminum. Any decrease in the EU import duty for primary aluminum negatively impacts Grundartangi’s revenues.

Table of Contents
Apart from the Glencore Metal Agreement, the Glencore Sweep Agreement, Glencore Nordural Metal Agreement and the Southwire Metal Agreements, we had forward delivery contracts to sell 41,504 and 47,926 metric tons of primary aluminum at December 31, 2011 and December 31, 2010, respectively. Of these forward delivery contracts, we had fixed price commitments to sell 41 and 117 metric tons of primary aluminum at December 31, 2011 and December 31, 2010, respectively, of which none were with Glencore at December 31, 2011 and December 31, 2010.
Forwards and Financial Purchase Agreements
Financial Purchase and Sales Agreements
Primary aluminum put option contracts
We enter into primary aluminum put option contracts that settle monthly based on LME prices. The put option contract volumes account for a portion of our domestic production level in 2012 with a strike price around our domestic facilities’ average cash basis break-even price. These options were purchased to partially mitigate the risk of a future decline in aluminum prices. See Note 5 Derivatives and hedging instruments in the consolidated financial statements for additional information about these contracts.
Natural gas forward financial contracts
To mitigate the volatility of our natural gas cost due to the natural gas markets, we have entered into fixed-price forward financial purchase contracts which settle in cash in the period corresponding to the intended usage of natural gas. These forward contracts were designated as cash flow hedges. On a hypothetical basis based on the forward natural gas financial purchase contracts outstanding at December 31, 2011, even a significant decrease in the market price of natural gas would not have a material impact on our financial results of operations, financial position or cash flows. See Note 5 Derivatives and hedging instruments in the consolidated financial statements for additional information about these contracts.
Foreign Currency
We are exposed to foreign currency risk due to fluctuations in the value of the U.S. dollar as compared to the euro, the Icelandic krona and the Chinese yuan. We may manage our foreign currency exposure by entering into foreign currency forward contracts. As of December 31, 2011, we had no foreign currency forward contracts outstanding. See Note 5 Derivatives and hedging instruments in the consolidated financial statements for additional information about these contracts.
Natural Economic Hedges
This quantification of our exposure to the commodity price of aluminum is necessarily limited, as it does not take into consideration our inventory or forward delivery contracts, or the offsetting impact on the sales price of primary aluminum products. Our alumina contracts are indexed to the LME price for primary aluminum and provide a natural hedge for approximately 16% of our production. As of December 31, 2011, approximately 33% of our production for 2012 was hedged by our LME-based alumina contracts and by Grundartangi’s electrical power and tolling contracts.
Risk Management
Our metals, foreign currency and natural gas risk management activities are subject to the control and direction of senior management within guidelines established by Century’s Board of Directors. These activities are regularly reported to Century’s Board of Directors.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of Century Aluminum Company:
We have audited the accompanying consolidated balance sheets of Century Aluminum Company and subsidiaries (the "Company") as of December 31, 2011 and 2010, and the related consolidated statements of operations, comprehensive income (loss), shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2011. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Century Aluminum Company and subsidiaries as of December 31, 2011 and 2010, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2011, in conformity with accounting principles generally accepted in the United States of America.
As discussed in Note 1 to the consolidated financial statements, the Company has changed its method of presenting comprehensive income in 2011 due to the adoption of FASB Accounting Standards Update No. 2011-05, Presentation of Comprehensive Income. The change in presentation has been applied retrospectively to all periods presented.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of December 31, 2011, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 29, 2012 expressed an unqualified opinion on the Company's internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of Century Aluminum Company:
We have audited the internal control over financial reporting of Century Aluminum Company and subsidiaries (the "Company") as of December 31, 2011, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Item 9A, Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.
Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule as of and for the year ended December 31, 2011 of the Company and our reports dated February 29, 2012 expressed an unqualified opinion on those financial statements and financial statement schedule and included an explanatory paragraph regarding the adoption of FASB Accounting Standards Update No. 2011-05, Presentation of Comprehensive Income.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 2011, 2010 AND 2009
(Dollars in thousands, except share and per share amounts)

1. | Summary of significant accounting policies

Organization and Basis of Presentation — Century Aluminum Company (“Century Aluminum,” “Century,” “we”, “us”, “our” or “ours”) is a holding company, whose principal subsidiaries are Century Kentucky, Inc., Nordural ehf (“Nordural”), Berkeley Aluminum, Inc. (“Berkeley”), and Century Aluminum of West Virginia, Inc. (“Century of West Virginia”). Century Kentucky, Inc. operates a primary aluminum reduction facility in Hawesville, Kentucky (“Hawesville”). Nordural Grundartangi ehf operates a primary aluminum reduction facility in Grundartangi, Iceland (“Grundartangi”). Century of West Virginia operates a primary aluminum reduction facility in Ravenswood, West Virginia (“Ravenswood”). Berkeley holds a 49.7% interest in a partnership which operates a primary aluminum reduction facility in Mt. Holly, South Carolina (“Mt. Holly”) and a 49.7% undivided interest in the property, plant, and equipment comprising Mt. Holly. The remaining interest in the partnership and the remaining undivided interest in Mt. Holly are owned by Alumax of South Carolina, Inc., a subsidiary of Alcoa. Alumax of South Carolina manages and operates Mt. Holly pursuant to an Owners Agreement, prohibiting the disposal of the interest held by any of the owners without the consent of the other owners and providing for certain rights of first refusal. Pursuant to the Owners Agreement, each owner furnishes their own alumina, for conversion to aluminum, and is responsible for their pro rata share of the operating and conversion costs.
We also own a 40% stake in Baise Haohai Carbon Co., Ltd. (“BHH”), a carbon anode and cathode facility located in the Guangxi Zhuang Autonomous Region of south China. BHH, in addition to its Chinese customers, supplies anodes to Grundartangi.
In August 2009, we divested our joint venture interests in the Gramercy alumina refinery, located in Gramercy, Louisiana (“Gramercy”) and St. Ann Bauxite Limited (“St. Ann”), a related bauxite mining operation in Jamaica.
Prior to our initial public offering, we were an indirect, wholly-owned subsidiary of Glencore International AG (together with its subsidiaries, “Glencore”). At December 31, 2011, Glencore owned 41.6% of Century’s outstanding common stock and all of our outstanding Series A Convertible Preferred stock. Century and Glencore enter into various transactions such as the purchase and sale of primary aluminum, purchase and sale of alumina, tolling agreements and primary aluminum put option contracts.
Principles of Consolidation — The consolidated financial statements include the accounts of Century Aluminum Company and our subsidiaries, after elimination of all significant intercompany transactions and accounts. Berkeley’s interest in the Mt. Holly partnership and our interest in the BHH joint venture and our past interest in the Gramercy and St. Ann joint ventures are accounted for under the equity method. Our equity in the earnings of St. Ann was recorded net of Jamaican taxes.
Revenue recognition— Revenue is recognized when title and risk of loss pass to customers in accordance with contract terms. In some instances, we invoice our customers prior to physical shipment of goods. In such instances, revenue is recognized only when the customer has specifically requested such treatment and has made a commitment to purchase the product. The goods must be complete, ready for shipment and physically separated from other inventory with risk of ownership passing to the customer. We must retain no performance obligations and a delivery schedule must be obtained.
Cash and Cash Equivalents — Cash and cash equivalents are comprised of cash, money market funds and short-term investments having original maturities of three months or less. The carrying amount of cash equivalents approximates fair value.
Accounts Receivable — The accounts receivable are net of an allowance for uncollectible accounts of $734 and $734 at December 31, 2011 and 2010, respectively.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Inventories — Our inventories are stated at the lower of cost (using the first-in, first-out (“FIFO”) method) or market.
Property, Plant and Equipment — Property, plant and equipment is stated at cost. Additions, renewals and improvements are capitalized. Asset and accumulated depreciation accounts are relieved for dispositions with resulting gains or losses included in other income (expense). Maintenance and repairs are expensed as incurred. We capitalize interest for the construction of qualifying assets. Depreciation of plant and equipment is provided for by the straight-line method over the following estimated useful lives:

| Buildings and improvements: | 14 to 45 years
| Machinery and equipment: | 5 to 22 years

We periodically evaluate the carrying value of long-lived assets to be held and used when events and circumstances warrant such a review. The carrying value of a separately identifiable, long-lived asset is considered impaired when the anticipated undiscounted cash flow from such asset is less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset. Fair value is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved. We did not recognize any impairment losses on our long-lived fixed assets during 2011, 2010 or 2009.
Intangible Assets – As of December 31, 2011 and 2010, we had no intangible assets. Our intangible asset prior to July 2009 consisted of the power contract acquired in connection with our 2001 acquisition of Hawesville. We entered into a new power agreement at Hawesville in July 2009 and expensed the remaining value of the intangible asset at that time. For the year ended December 31, 2009, amortization expense for the intangible asset totaled $8,769.
Other Assets — Other assets consist primarily of Century’s investment in the Mt. Holly partnership, investments in joint ventures, deferred financing costs, a Rabbi trust to fund the non-qualified SERB benefit obligation, cash surrender value of life insurance policies and operating maintenance supplies not expected to be consumed within the year. Our equity share of the undistributed earnings (loss) increases (decreases) the investment in the joint ventures. Deferred financing costs are amortized on a straight-line basis over the life of the related financial instrument.
We account for our interest in the Mt. Holly partnership using the equity method of accounting. Additionally, our undivided interest in certain property, plant and equipment of Mt. Holly is held outside of the partnership and the undivided interest in these assets of the facility is accounted for in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810-10-45-14 “Investor Balance Sheet and Income Statement Display under the Equity Method for Investments in Certain Partnerships and Other Ventures”. Accordingly, the undivided interest in these assets and the related depreciation are being accounted for on a proportionate gross basis.
Income Taxes — We account for income taxes using the liability method, whereby deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. In evaluating our ability to realize deferred tax assets, we use judgment in considering the relative impact of negative and positive evidence. The weight given to the potential effect of negative and positive evidence is commensurate with the extent to which it can be objectively verified. Based on the weight of evidence, both negative and positive, if it is more likely than not that some portion or all of a deferred tax asset will not be realized, a valuation allowance is established. Accordingly, we have a valuation allowance against a portion of our federal and state deferred tax assets due to our belief that it is more likely than not that these assets will not be realized. We have a valuation allowance against a portion of our Icelandic and Hong Kong net operating losses (“NOL”) deferred tax assets due to our belief that it is more likely than not that these assets will not be realized. See Note 14 Income Taxes for additional information.

We have removed our election to permanently reinvest foreign earnings for 2011, 2010 and 2009.
Postemployment Benefits — We provide certain postemployment benefits to former and inactive employees and their dependents during the period following employment, but before retirement. These benefits include salary continuance, supplemental unemployment and disability healthcare. We recognize the estimated future cost of providing postemployment benefits on an accrual basis over the active service life of the employee.
Derivatives and hedging — We routinely enter into fixed and market priced contracts for the sale of primary aluminum and the purchase of raw materials in future periods. We also enter into fixed price financial sales contracts and put option contracts to be settled in cash to manage our exposure to changing primary aluminum prices. We have also entered into financial purchase contracts for natural gas to be settled in cash to manage our exposure to changing natural gas prices.
Certain physical delivery and financial sales contracts for primary aluminum are not designated cash flow hedges or do not qualify for cash flow hedge treatment are marked-to-market quarterly. Fluctuations in the London Metal Exchange (“LME”) price of primary aluminum may have a significant impact on gains and losses included in our financial statements from period to period. We recognize the unrealized and realized gains and losses associated with these contracts in net gain (loss) on forward contracts. Our power supply agreement at Ravenswood contains LME-based pricing provisions that are an embedded derivative. The embedded derivative does not qualify for cash flow hedge treatment and is marked to market quarterly.
See Note 4 Fair Value Measurements and Note 5 Derivatives and hedging instruments for additional information about these contracts.
Foreign Currency – We are exposed to foreign currency risk due to fluctuations in the value of the U.S. dollar as compared to the euro, the Icelandic krona (“ISK”) and the Chinese yuan. Nordural uses the U.S. dollar as its functional currency, however a portion of the operating expenses of the Grundartangi facility are denominated and payable in currencies other than the U.S. dollar. Grundartangi’s labor and certain other local costs are denominated in ISK and a portion of its anode costs are denominated in euros. Transactions denominated in currencies other than the functional currency are recorded based on exchange rates at the time such transactions arise and any transaction gains and losses are reflected in other income (expense) in the consolidated statements of operations. In addition, our joint venture investment in BHH uses the Chinese yuan as its functional currency. For our joint venture investments, we record gains and losses associated with foreign currency exchange rates in equity in earnings of joint ventures.
Financial Instruments — Our receivables, payables and debt related to industrial revenue bonds (“IRBs”) are carried at amounts that approximate fair value. The following table provides the carrying amounts and approximate fair value (based the last available trading data) of our 8.0% senior notes due 2014 (the “8.0% Notes”), our 7.5% senior unsecured notes due 2014 (the “7.5% Notes”) and our 1.75% convertible senior notes due 2024 (the “1.75% Notes”).

Concentration of Credit Risk — Financial instruments, which potentially expose us to concentrations of credit risk, consist principally of trade receivables and primary aluminum put option contracts. Our limited customer base increases our concentrations of credit risk with respect to trade receivables. We routinely assess the financial strength of our customers and collectability of our trade receivables.
Use of Estimates — The preparation of financial statements in conformity with generally accepted accounting principles in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Stock-Based Compensation —We use the Black-Scholes option-pricing model to estimate the fair value of our stock option grants and service-based share awards on the grant date of the share award. Information about our assumptions used to determine the fair value of the grants in 2011, 2010 and 2009 is available in Note 12 Share-based Compensation.
Recently Issued Accounting Standards – We evaluate the impact of FASB accounting standards updates (“ASUs”) issued. When the adoption or planned adoption of recently issued ASUs will potentially have a material impact on our consolidated financial position, results of operations, and cash flows, we disclose the quantitative and qualitative effects of the adoption in our consolidated financial statements.
Recently Adopted Accounting Standards– In June 2011, the FASB issued ASU 2011-05, “Comprehensive Income”. This ASU addresses the financial statement presentation of other comprehensive income and its components. Companies may elect to present items of net income and other comprehensive income in one continuous statement or in two separate, but consecutive, statements. This guidance will only impact the presentation of our financial statements and have no impact on our financial position, results of operations or cash flows. We elected to adopt ASU 2011-05 early and have included the updated presentation requirements in the current financial statements.
In September 2011, the FASB issued ASU 2011-09, “Disclosure about an Employer’s Participation in Multiemployer Benefit Plans,” which amends current pension disclosure requirements by increasing the quantitative and qualitative disclosures that we are required to provide about our participation in significant multiemployer plans that offer pension and other postretirement benefits. The ASU’s objective is to enhance the transparency of disclosures about (1) the significant multiemployer plans in which we participate, (2) the level of our participation in those plans, (3) the financial health of the plans, and (4) the nature of our commitments to the plans. We adopted ASU 2011-09 in 2011. This guidance impacted only the disclosures within our financial statements and had no impact on our financial position, results of operations or cash flows. The ASU is effective for our current fiscal year ending December 31, 2011. See Note 11 Pension and other postemployment benefits for additional information.

2. | Long-term power contract for Hawesville

In July 2009, our wholly owned subsidiary, Century Aluminum of Kentucky (“CAKY”) along with E.ON U.S. (“E.ON”) and Big Rivers Energy Corporation (“Big Rivers” or “BREC”), agreed to an “unwind” of the former contractual arrangement between Big Rivers and E.ON and entered into a new arrangement (“Big Rivers Agreement”) to provide long-term cost-based power to CAKY. The term of the Big Rivers Agreement is through 2023 and provides adequate power for full production capacity requirements for Hawesville (approximately 482 megawatts (“MW”)) with pricing based on the power provider’s cost of production. The Big Rivers Agreement is take-or-pay for Hawesville’s energy requirements at full production. Under the terms of the agreement, any power not consumed by Hawesville would be available for sale and we would receive credits for actual power sales up to our cost for that power.
In connection with the “unwind,” E.ON agreed to mitigate a significant portion of the near-term risk of this agreement through December 2010. During this time, to the extent Hawesville did not use all the power under the take-or-pay contract, E.ON, with some limitations, assumed CAKY's obligations under the former power contract. This effectively resulted in CAKY paying prices which approximated the previous contract prices and volume protection resulting in CAKY receiving credits for unused power without sustaining a loss. Hawesville received these economic benefits during 2009 and 2010.
Under the terms of the “unwind,” to the extent the aggregate payments made by E.ON exceeded an agreed upon base amount, CAKY is obligated to repay this excess to E.ON over time under certain conditions. The aggregate balance due to E.ON is recorded in other liabilities. The repayment obligation is contingent upon certain operating criteria and the LME price of primary aluminum. See Note 6 Debt for additional information about the E.ON contingent obligation.
During 2011, we paid the full production cost of power under the Big Rivers Agreement. During 2010 and 2009, the full production cost of power was recorded in our cost of goods sold, however we realized benefits of $68,794 and $26,025 for 2010 and 2009, respectively, for E.ON payments made on CAKY’s behalf, including amounts incurred for the E.ON contingent obligation.
As the previous power contract was designated as a normal contract under ASC 815, in 2009 when it became no longer probable that we would continue to take physical delivery of the power under the previous contract, we recorded a contractual receivable from E.ON representing the net present value of the consideration provided to CAKY from E.ON to net settle the previous contract. We also expensed an intangible asset associated with the former power contract and recorded a $56,964 net gain on this transaction on our consolidated statements of operations in other operating income – net.
The new power contract has been designated as a normal purchase contract under ASC 815. The Big Rivers Agreement is a cost-based contract that is not expected to have any significant value and is with a regulated power generator. While the Big Rivers Agreement is a take-or-pay contract, under which we may net settle any unused power with Big Rivers, we would only receive credits up to our cost for such power sales and would not profit on any sales made above our cost for such power under the current election.

3. | Curtailment of operations – Ravenswood and Hawesville

In February 2009, Century Aluminum of West Virginia, Inc. fully curtailed its plant operations at Ravenswood. Layoffs for the majority of Ravenswood's employees were completed in February 2009. The decision to curtail operations was due to the relatively high operating cost at Ravenswood and the depressed global price for primary aluminum.

CENTURY ALUMINUM COMPANY
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)
In March 2009, CAKY curtailed one of its five potlines at Hawesville. The action reduced primary aluminum production by approximately 49,000 metric tons per year. We restarted the curtailed potline at Hawesville in 2011. As of December 31, 2011, Hawesville was essentially at full production capacity.
We incurred curtailment charges (benefits) of $(3,806), $(37,386) and $41,710 during the years ended December 31, 2011, 2010 and 2009, respectively, which are reported in other operating income - net in the Consolidated Statements of Operations. The majority of the curtailment charges are related to Ravenswood. The components of the curtailment costs are as follows:

4. | Fair value measurements

ASC 820 “Fair Value Measurements and Disclosures” defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. This pronouncement applies to a broad range of other existing accounting pronouncements that require or permit fair value measurements. ASC 820 defines fair value as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” Fair value is an exit price and that exit price should reflect all the assumptions that market participants would use in pricing the asset or liability.
ASC 820 recognizes three valuation techniques; the market approach, income approach, and/or cost approach. Valuation techniques used for fair value measurements are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our internal market assumptions. These two types of inputs create the following fair value hierarchy:

| · | Level 1 – Valuations are based on quoted prices for identical assets or liabilities in an active market.

| · | Level 2 – Valuations are based on quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and model-derived valuations for which all significant inputs are observable or can be corroborated by observable market data.

| · | Level 3 – Assets or liabilities whose significant inputs are unobservable. Valuations are determined using pricing models and discounted cash flow models and include management judgment and estimation which may be significant.

- 61 -

Table of Contents
CENTURY ALUMINUM COMPANY
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Our fair value measurements include the consideration of market risks that other market participants might consider in pricing the particular asset or liability, specifically non-performance risk and counterparty credit risk. Consideration of the non-performance risk and counterparty credit risk are used to establish the appropriate risk-adjusted discount rates used in our fair value measurements.
The following section describes the valuation methodology used to measure our financial assets and liabilities that were accounted for at fair value.

Overview of Century’s valuation methodology
| Level | Significant inputs
Money market funds | 1 | Quoted market prices
Trust assets (1) | 1 | Quoted market prices
Surety bonds | 1 | Quoted market prices
Primary aluminum put/call option contracts | 2 | Quoted LME forward market prices, historical volatility measurements and risk-adjusted discount rates
Natural gas forward financial purchase contracts | 2 | Quoted natural gas forward market prices and risk-adjusted discount rates
Power contracts | 3 | Quoted LME forward market prices, power tariff prices, management’s estimate of future power usage and risk-adjusted discount rates
E.ON contingent obligation | 3 | Quoted LME forward market, management’s estimates of the LME forward market prices for periods beyond the quoted periods and management’s estimate of future level of operations at CAKY.
Primary aluminum sales premium contracts | 3 | Management’s estimates of future U.S. Midwest premium and risk-adjusted discount rates

(1) | Trust assets are currently invested in money market funds. The trust has sole authority to invest the funds in secure interest producing investments consisting of short-term securities issued or guaranteed by the United States government or cash and cash equivalents.

Fair Value Measurements
The following table sets forth our financial assets and liabilities that were accounted for at fair value on a recurring basis by the level of input within the ASC 820 fair value hierarchy. As required by GAAP for fair value measurements and disclosures, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and the placement within the fair value hierarchy levels.

5. | Derivative and hedging instruments

Derivatives. Our derivative contracts have included natural gas forward financial purchase contracts, foreign currency contracts, primary aluminum forward physical delivery sales contracts, the E.ON contingent obligation, the Ravenswood power contract and primary aluminum put option contracts. We measure the fair value of these contracts based on the quoted future market prices (if available) at the reporting date in their respective principal markets for all available periods. In some cases, we use discounted cash flows from these contracts using a risk-adjusted discount rate. See Note 4 Fair value measurements for the additional information about the fair value measurement of our derivative instruments.

The natural gas forward financial contracts are derivatives that qualified for cash flow hedge treatment. During 2011 and 2010, the changes in our accumulated other comprehensive loss resulting from realized and unrealized gains and losses on these derivatives were not significant to our financial statements. There were no losses recognized for ineffective portions of these derivatives during the periods.
As of December 31, 2011, an accumulated other comprehensive loss of $196 is expected to be reclassified to earnings over the next 12-month period.
Natural gas forward financial contracts
To mitigate the volatility of our natural gas cost due to the natural gas markets, we have entered into fixed-price forward financial purchase contracts which settle in cash in the period corresponding to the intended usage of natural gas. These forward contracts are designated as cash flow hedges and qualify for hedge accounting under ASC 815. The critical terms of the contracts essentially match those of the underlying exposure.
The effective portion of the natural gas forward financial contracts is reported in accumulated other comprehensive loss, and the ineffective portion is reported currently in earnings. Each month, when we settle the natural gas forward financial contracts, the realized gain or loss is recognized in income as part of our cost of goods sold.

Table of Contents
CENTURY ALUMINUM COMPANY
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)
We had the following outstanding forward financial purchase contracts to hedge forecasted transactions:

|  | December 31, 2011 | December 31, 2010
| Natural gas forward financial purchase contracts (in MMBTU) | 350,000 | 250,000

Foreign currency forward contracts
As of December 31, 2011, we had no foreign currency forward contracts outstanding. We are exposed to foreign currency risk due to fluctuations in the value of the U.S. dollar as compared to the euro, the ISK and the Chinese yuan. The labor costs, maintenance costs and other local services at Grundartangi are denominated in ISK and a portion of its anode costs are denominated 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 operating margins.
We manage our foreign currency exposure by entering into foreign currency forward contracts when management deems such transactions appropriate. During 2008 and 2009, we had foreign currency forward contracts to manage the currency risk associated with Grundartangi operating costs, Grundartangi expansion and the Helguvik project capital expenditures. These contracts were designated as cash flow hedges and qualified for hedge accounting under ASC 815 and had maturities through September 2009.
The realized gains or losses for our cash flow hedges for the Grundartangi expansion and Helguvik project capital expenditures were recognized in accumulated other comprehensive income and will be reclassified to earnings as part of the depreciation expense of the capital assets (for the Helguvik project this will occur when Helguvik is put into service).
We recognized losses of approximately $1,701 for the year ended December 31, 2009 on the ineffective portions of the forward contracts for the forecasted Helguvik project capital expenditures. These losses are recorded in net gain (loss) on forward contracts in our consolidated statements of operations. The ineffective portion of these forward contracts represents forward contract positions in excess of the revised forecast schedule of Helguvik project capital expenditures.
Power contracts
We are party to a power supply agreement at Ravenswood that contains LME-based pricing provisions that are an embedded derivative. The embedded derivative does not qualify for cash flow hedge treatment and is marked to market quarterly. We estimate the fair value of the embedded derivative based on our expected power usage over the remaining term of the contract, gains and losses associated with the embedded derivative are recorded in net gain (loss) on forward contracts in the Consolidated Statements of Operations.
Primary aluminum put option contracts
We have entered into primary aluminum put option contracts that settle monthly based on LME prices through June 2012. The option contract volumes account for a portion of our domestic production, with a strike price around our domestic facilities’ average cash basis break-even price. These options were purchased to partially mitigate the risk of a future decline in aluminum prices.

Our counterparties include two non-related third parties and Glencore, a related party. We paid cash premiums to enter into the put option contracts and recorded an asset on the consolidated balance sheets. We determined the fair value of the put contracts using a Black-Scholes model with market data provided by an independent vendor and account for the contracts as derivative financial instruments with gains and losses in the fair value of the contracts recorded on the consolidated statements of operations in net gain (loss) on forward contracts.
Aluminum sales premium contracts
The Glencore Metal Agreement is a physical delivery contract for primary aluminum through December 31, 2013 with variable, LME-based pricing. Under the Glencore Metal Agreement, pricing is based on market prices, adjusted by a negotiated U.S. Midwest premium with a cap and a floor as applied to the current U.S. Midwest premium. We account for the Glencore Metal Agreement as a derivative instrument under ASC 815. Gains and losses on the derivative are based on the difference between the contracted U.S. Midwest premium and actual and forecasted U.S. Midwest premiums. Settlements are recorded in related party sales. Unrealized gains (losses) based on forecasted U.S. Midwest premiums are recorded in net gain (loss) on forward contracts on the consolidated statements of operations.

Counterparty credit risk. The primary aluminum put option contracts are subject to counterparty credit risk. However, we only enter into forward financial contracts with counterparties we determine to be creditworthy at the time of entering into the contract. If any counterparty failed to perform according to the terms of the contract, the impact would be limited to the difference between the contract price and the market price applied to the contract volume on the date of settlement.

(2) | E.ON contingent obligation principal and interest payments are payable based on CAKY’s operating level and the LME price for primary aluminum. See E.ON contingent obligation below.

Revolving Credit Facility
General. On July 1, 2010, we and certain of our direct and indirect domestic subsidiaries (together with Century, the "Borrowers") entered into a four-year $100,000 senior secured revolving credit facility pursuant to a Loan and Security Agreement, dated as of July 1, 2010, among the Borrowers and Wells Fargo Capital Finance, LLC, as lender and agent (the "Credit Facility"), a portion of which was later syndicated to Credit Suisse AG. The Credit Facility replaced our previous credit facility that would have expired on September 19, 2010.
The Credit Facility provides for borrowings of up to $100,000 in the aggregate, including up to $50,000 under a letter of credit sub-facility. Any letters of credit issued and outstanding under the Credit Facility reduce our borrowing availability on a dollar-for-dollar basis. As of December 31, 2011, we had no outstanding borrowings under the Credit Facility, although the Borrowers may in the future use the Credit Facility to repay existing indebtedness, to issue standby or commercial letters of credit, to finance capital expenditures and for ongoing working capital needs and other general corporate purposes. As of December 31, 2011, the borrowing availability, net of $41,451 for outstanding letters of credit, was approximately $57,473 under the Credit Facility.
The availability of funds under the revolving credit facility is limited by a specified borrowing base consisting of accounts receivable and inventory which meet the eligibility criteria. The availability of funds under the revolving credit facility is limited by a specified borrowing base consisting of a portion of eligible accounts receivable not owed by Glencore plus a portion of the net amount of eligible accounts receivable owed by Glencore and a portion of eligible inventory balance.
Guaranty. The Borrowers' obligations under the Credit Facility are guaranteed by certain of our domestic subsidiaries and secured by a first priority security interest in all of the Borrowers' accounts receivable, inventory and certain bank accounts. Each Borrower is liable for any and all obligations under the Credit Facility on a joint and several basis.

Interest Rates and Fees. Any amounts outstanding under the Credit Facility will bear interest, at our option, at LIBOR or a base rate, plus, in each case, an applicable interest margin. The applicable interest margin is determined based on the average daily availability for the immediately preceding quarter. For amounts outstanding under the revolving credit facility, the applicable interest margin ranges from 2.50% to 3.00% over the LIBOR rate and 1.50% under to 2.00% over the base rate. In addition, we pay a commitment fee of 0.50% per annum on undrawn amounts, less the amount of our letters of credit exposure.
For standby letters of credit, we are required to pay a fee on the face amount of such letters of credit equal to either 0.75% (if 100% supported by cash collateral) or 2.50% (for all other standby letters of credit).
Maturity. The Credit Facility will mature on July 1, 2014.
Prepayments. We can make voluntary prepayments of amounts outstanding under the Credit Facility, in whole or in part without premium or penalty, subject to standard LIBOR breakage costs. We are required to apply the proceeds from sales of accounts receivable or inventory, other than sales of inventory in the ordinary course of business, to repay amounts outstanding under the revolving credit facility and correspondingly reduce the commitments there under.
Covenants. The Credit Facility contains customary covenants, including restrictions on mergers and acquisitions, indebtedness, affiliate transactions, liens, dividends and distributions, dispositions of collateral, investments and prepayments of indebtedness, as well as a covenant that requires the Borrowers to maintain certain minimum liquidity or availability requirements.
Events of Default. The Credit Facility also includes customary events of default, including nonpayment, misrepresentation, breach of covenant, bankruptcy, change of ownership, certain judgments and certain cross defaults. Upon the occurrence of an event of default, commitments under the Credit Facility may be terminated and amounts outstanding may be accelerated and declared immediately due and payable.
1.75% Notes
On May 19, 2011, we redeemed all outstanding 1.75% Notes at 100% of the principal amount plus accrued and unpaid interest to that date. We funded the redemption of the 1.75% Notes with cash on hand.
Interest Rate. The 1.75% Notes bear interest at 1.75% per annum on the principal amount, payable semi-annually in arrears in cash on February 1 and August 1 of each year.

Exchange offer and consent solicitation. In 2010 and 2009, we completed a series of debt for debt exchange offers and consent solicitation relating to our 7.5% Notes (the “7.5% Notes Exchange Offer”) in which we issued our 8.0% Notes in exchange for our 7.5% Notes. In addition, certain investors consented to certain amendments and modifications to the indenture governing the 7.5% Notes to remove, among other things, most of the restrictive covenants, in exchange for which we paid these investors consent fees. As of December 31, 2011, we had $2,603 of aggregate principal amount outstanding of the 7.5% Notes.
Interest rate. The 7.5% Notes bear interest at 7.5% per annum on the principal amount, payable semi-annually in arrears in cash on February 15 and August 15 of each year.
Maturity. The 7.5% Notes mature on August 15, 2014.
Seniority. The 7.5% Notes are senior unsecured obligations and rank, in right of payment, the same as all of our existing and future senior unsecured debt, including the 1.75% Notes.
Guaranty. Our obligations under the 7.5% Notes are guaranteed by all of our existing and future domestic restricted subsidiaries.
Redemption Rights. On or after August 15, 2011, we may redeem the 7.5% Notes, in whole or in part, at a redemption price equal to 101.5% of the principal amount, plus accrued and unpaid interest. The redemption price will decline to 100% of the principal amount, plus accrued and unpaid interest, on August 15, 2012.
Upon a “change of control” (as defined in the indenture governing the 7.5% Notes), we will be required to make an offer to purchase the 7.5% Notes at a purchase price equal to 101% of the outstanding principal amount of the 7.5% Notes on the date of the purchase, plus accrued interest to the date of purchase.
Covenants and Exchange Offer. In December 2009, the indenture governing the 7.5% Notes was amended in connection with the 7.5% Notes Exchange Offer to remove most of the restrictive covenants, see consent solicitation discussion above.
8.0% Notes
General. As of December 31, 2011, we have issued $249,604 of our 8.0% Notes in a series of exchange transactions for our 7.5% Notes in a private offering exempt from the registration requirements of the Securities Act. See Exchange offer and consent solicitation under the 7.5% Notes above.
Interest rate. The 8.0% Notes bear interest at 8.0% per annum on the principal amount, payable semi-annually in arrears in cash on May 15 and November 15 of each year.
Maturity. The 8.0% Notes mature on May 15, 2014.
Seniority. The 8.0% Notes are senior secured obligations of Century, ranking equally in right of payment with all existing and future senior indebtedness of Century, but effectively senior to unsecured debt to the extent of the value of the collateral.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Guaranty. Our obligations under the 8.0% Notes are guaranteed by all of our existing and future domestic restricted subsidiaries, except for foreign owned parent companies (the “Guarantors”), which guaranty shall in each case be a senior secured obligation of such Guarantors, ranking equally in right of payment with all existing and future senior indebtedness of such Guarantor but effectively senior to unsecured debt.
Collateral. Our obligations under the 8.0% Notes and the guarantors’ obligations under the guarantees will be secured by a pledge of and lien on (subject to certain exceptions):

| (i) | all of our and the guarantors’ plant, property and equipment;
| (ii) | all equity interests in domestic subsidiaries directly owned by us and the guarantors and 65% of equity interests in foreign subsidiaries directly owned by us and the guarantors;
| (iii) | intercompany notes owed by any non-guarantor to us or any guarantor, including an intercompany note from Century Bermuda I Ltd. (which indirectly owns Grundartangi and Helguvik) to us; and
| (iv) | proceeds of the foregoing.

The liens securing the 8.0% Notes will not extend to assets other than those described above.
Under certain circumstances, the indenture and the security documents governing the 8.0% Notes will permit us and the guarantors to incur additional debt that also may be secured by liens on the collateral that are equal to or have priority over the liens securing the 8.0% Notes. The collateral agent for the 8.0% Notes will agree with the collateral agent for the other debt holders and us under such circumstances to enter into an intercreditor agreement that will cause the liens securing the 8.0% Notes to be contractually subordinated to the liens securing such additional debt.
Redemption Rights. On or after May 15, 2011, we may redeem the 8.0% Notes, in whole or in part, at an initial redemption price equal to 104% of the principal amount, plus accrued and unpaid interest. The redemption price will decline to 102% on May 15, 2012 and will be 100% of the principal amount, plus accrued and unpaid interest, beginning on May 15, 2013 and thereafter.
Upon a change of control (as defined in the indenture governing the 8.0% Notes), we will be required to make an offer to purchase the 8.0% Notes at a purchase price equal to 101% of the outstanding principal amount of the 8.0% Notes on the date of the purchase, plus accrued interest to the date of purchase.
Covenants. The indenture governing the 8.0% Notes limits our ability, and the ability of certain of our subsidiaries, to: (i) incur additional debt; (ii) create liens; (iii) pay dividends or make distributions in respect of capital stock; (iv) purchase or redeem capital stock; (v) make investments or certain other restricted payments; (vi) sell assets; (vii) issue or sell stock of certain subsidiaries; (viii) enter into transactions with shareholders or affiliates; and (ix) effect a consolidation or merger.
E.ON contingent obligation
General. The E.ON contingent obligation consists of the aggregate E.ON payments under the Big Rivers Agreement to Big Rivers on CAKY’s behalf in excess of the agreed upon base amount. Our obligation to make repayments is contingent upon certain operating criteria for Hawesville and the LME price of primary aluminum. Based on the LME forward market and our expectation of Hawesville’s future operations, we expect that we will be obligated to make payments in the future. When the conditions for repayment are met, and for so long so those conditions continue to be met, we will be obligated to make principal and interest payments, in up to 72 monthly payments.

7. | Shareholders’ Equity

Common Stock
Under our Restated Certificate of Incorporation, our Board of Directors is authorized to issue up to 195,000,000 shares of common stock.
The rights, preferences, and privileges of holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock, which are currently outstanding, including our Series A Convertible Preferred Stock, or which we may designate and issue in the future.
Stock Repurchase Program
In August 2011, our Board of Directors approved a $60,000 stock repurchase program. Under the program, we may repurchase up to $60,000 of our outstanding shares of common stock from time to time on the open market at prevailing market prices, in block trades or otherwise. The timing and amount of any shares repurchased will be determined by our management based on its evaluation of market conditions, the trading price of the stock and other factors. The repurchase program may be suspended or discontinued at any time.
- 71 -

Table of Contents
CENTURY ALUMINUM COMPANY
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Shares of common stock repurchased are recorded at cost as treasury stock and result in a reduction of shareholders’ equity in the consolidated balance sheets. From time to time, treasury shares may be reissued as contributions to our employee benefit plans and for the conversion of convertible preferred stock. When shares are reissued, we use an average cost method for determining cost. The difference between the cost of the shares and the reissuance price is added to or deducted from additional paid-in capital.
From August 11, 2011 through December 31, 2011, we repurchased 4,386,521 shares of common stock at an aggregate purchase price of $45,891. We had approximately $14,109 remaining under the repurchase program authorization as of December 31, 2011.
Preferred Stock
Under our Restated Certificate of Incorporation, our Board of Directors is authorized to issue up to 5,000,000 shares of preferred stock. Our Board of Directors may issue preferred stock in one or more series and determine for each series the dividend rights, conversion rights, voting rights, redemption rights, liquidation preferences, sinking fund terms and the number of shares constituting that series, as well as the designation thereof. Depending upon the terms of preferred stock established by our Board of Directors, any or all of the preferred stock could have preference over the common stock with respect to dividends and other distributions and upon the liquidation of Century. In addition, issuance of any shares of preferred stock with voting powers may dilute the voting power of the outstanding common stock.
Series A Convertible Preferred Stock
Shares Authorized and Outstanding. In 2008, we issued 160,000 shares of our Series A Convertible Preferred Stock. Glencore holds all shares of the issued and outstanding Series A Convertible Preferred Stock.
The issuance of common stock under our stock incentive programs, certain debt exchange transactions, and any stock offering that excludes Glencore participation triggers anti-dilution provisions of the preferred stock agreement and results in the automatic conversion of shares of Series A Convertible Preferred Stock into shares of common stock. Our Series A Convertible Preferred Stock has a par value of $0.01 per share. The following table shows Series A Convertible Preferred Stock conversions during 2011 and 2010:

Series A Convertible Preferred Stock: |  | 2011 |  |  | 2010 |
Shares outstanding at January 1, |  |  | 82,515 |  |  |  | 83,452 |
Automatic conversions during the year |  |  | (1,797 | ) |  |  | (937 | )
Total shares outstanding at December 31, |  |  | 80,718 |  |  |  | 82,515 |

Dividend Rights. So long as any shares of our Series A Convertible Preferred Stock are outstanding, we may not pay or declare any dividend or make any distribution upon or in respect of our common stock or any other capital stock ranking on a parity with or junior to the Series A Convertible Preferred Stock in respect of dividends or liquidation preference, unless we, at the same time, declare and pay a dividend or distribution on the shares of Series A Convertible Preferred Stock (a) in an amount equal to the amount such holders would receive if they were the holders of the number of shares of our common stock into which their shares of Series A Convertible Preferred Stock are convertible as of the record date fixed for such dividend or distribution, or (b) in the case of a dividend or distribution on other capital stock ranking on a parity with or junior to the Series A Convertible Preferred Stock in such amount and in such form as (based on the determination of holders of a majority of the Series A Convertible Preferred Stock) will preserve, without dilution, the economic position of the Series A Convertible Preferred Stock relative to such other capital stock.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Voting Rights. The Series A Convertible Preferred Stock has no voting rights for the election of directors or on other matters where the shares of common stock have voting rights. However, we may not change the powers, preferences, or rights given to the Series A Convertible Preferred Stock, or authorize, create or issue any additional shares of Series A Convertible Preferred Stock without the affirmative vote of the holders of a majority of the shares of Series A Convertible Preferred Stock then outstanding (voting separately as a class).
Liquidation Rights. Upon any liquidation, dissolution, or winding-up of Century, the holders of shares of Series A Convertible Preferred Stock are entitled to receive a preferential distribution of $0.01 per share out of the assets available for distribution. In addition, upon any liquidation, dissolution or winding-up of Century, if our assets are sufficient to make any distribution to the holders of the common stock, then the holders of shares of Series A Convertible Preferred Stock are also entitled to share ratably with the holders of common stock in the distribution of Century’s assets (as though the holders of Series A Convertible Preferred Stock were holders of that number of shares of common stock into which their shares of Series A Convertible Preferred Stock are convertible). However, the amount of any such distribution will be reduced by the amount of the preferential distribution received by the holders of the Series A Convertible Preferred Stock.
Transfer Restrictions. Glencore is prohibited from transferring shares of Series A Convertible Preferred Stock to any party other than an affiliate who agrees to become bound by certain agreements associated with these shares.
Automatic Conversion. The Series A Convertible Preferred Stock automatically converts, without any further act of Century or any holders of Series A Convertible Preferred Stock, into shares of common stock, at a conversion ratio of 100 shares of common stock for each share of Series A Convertible Preferred Stock, upon the occurrence of any of the following automatic conversion events:

| • | If we sell or issue shares of common stock or any other stock that votes generally with our common stock, or the occurrence of any other event, including a sale, transfer or other disposition of common stock by Glencore, as a result of which the percentage of voting stock held by Glencore decreases, an amount of Series A Convertible Preferred Stock will convert to common stock to restore Glencore to its previous ownership percentage;
| • | If shares of Series A Convertible Preferred Stock are transferred to an entity that is not an affiliate of Glencore, such shares of Series A Convertible Preferred Stock will convert to shares of our common stock, provided that such transfers may only be made pursuant to an effective registration statement;
| • | Upon a sale of Series A Convertible Preferred Stock by Glencore in a Rule 144 transaction in which the shares of Series A Convertible Preferred Stock and our common stock issuable upon the conversion thereof are not directed to any purchaser, such shares of Series A Convertible Preferred Stock sold will convert to shares of our common stock; and
| • | Immediately prior to and conditioned upon the consummation of a merger, reorganization or consolidation to which we are a party or a sale, abandonment, transfer, lease, license, mortgage, exchange or other disposition of all or substantially all of our property or assets, in one or a series of transactions where, in any such case, all of our common stock would be converted into the right to receive, or exchanged for, cash and/or securities, other than any transaction in which the Series A Convertible Preferred Stock will be redeemed.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Optional Conversion. Glencore has the option to convert the Series A Convertible Preferred Stock in a tender offer or exchange offer in which a majority of the outstanding shares of our common stock have been tendered by the holders thereof and not duly withdrawn at the expiration time of such tender or exchange offer, so long as the Series A Convertible Preferred Stock is tendered or exchanged in such offer.
Stock Combinations; Adjustments. If, at any time while the Series A Convertible Preferred Stock is outstanding, Century combines outstanding common stock into a smaller number of shares, then the number of shares of common stock issuable on conversion of each share of Series A Convertible Preferred Stock will be decreased in proportion to such decrease in the aggregate number of shares of common stock outstanding.
Redemptions or Repurchases of Common Stock. We may not redeem or repurchase our common stock unless we redeem or repurchase, or otherwise make a payment on, a pro rata number of shares of the Series A Convertible Preferred Stock. These restrictions do not apply to our open market repurchases or our repurchases pursuant to our employee benefit plans.
Right of Redemption. The Series A Convertible Preferred Stock will be redeemed by Century if any of the following events occur (at a redemption price based on the trading price of our common stock prior to the announcement of such event) and Glencore votes its shares of our common stock in opposition to such events:

| • | We propose a merger, reorganization or consolidation, sale, abandonment, transfer, lease, license, mortgage, exchange or other disposition of all or substantially all of our property or assets where any of our common stock would be converted into the right to receive, or exchanged for, assets other than cash and/or securities traded on a national stock exchange or that are otherwise readily marketable, or
| • | We propose to dissolve and wind up any assets other than cash and/or securities traded on a national stock exchange or that are otherwise readily marketable are to be distributed to the holders of our common stock.

11. | Pension and Other Postretirement Benefits

Pension Benefits
We maintain noncontributory defined benefit pension plans for all of our domestic hourly and salaried employees. For the domestic salaried employees, plan benefits are based primarily on years of service and average compensation during the later years of employment. For hourly employees at Ravenswood, plan benefits are based primarily on a formula that provides a specific benefit for each year of service. Our funding policy is to contribute amounts based upon actuarial and economic assumptions designed to achieve adequate funding of the projected benefit obligations and to meet the minimum funding requirements of the Employee Retirement Income Security Act 1974 (“ERISA”). Plan assets consist principally of U.S. and international equities and fixed income securities. In addition, we provide supplemental executive retirement benefits (“SERB”) for certain current and former executive officers. We account for these plans in accordance with ASC 715-30. We use a measurement date of December 31st to determine the pension and OPEB liabilities.
Employer contributions
In June 2011, at the time three directors designated for nomination to our Board of Directors were elected, it was determined a “change of control” occurred under the terms of our non-qualified SERB plan. As a result, we were required to make an approximately $16,700 contribution to a Rabbi trust to fully fund the non-qualified SERB benefit obligation. In addition, through December 31, 2011, we have made contributions of approximately $17,700 to the qualified defined benefit plans we sponsor for a total of approximately $34,400 in qualified defined benefit plan and non-qualified SERB contributions during the year.
Other Postretirement Benefits (OPEB)
In addition to providing pension benefits, we provide certain healthcare and life insurance benefits for certain domestic retired employees. We account for these plans in accordance with ASC 715-60. ASC 715-60 requires companies to accrue the estimated cost of providing postretirement benefits during the working careers of those employees who could become eligible for such benefits when they retire. We fund these benefits as the retirees submit claims.

Retiree Medical Benefits changes
In 2009 and 2010, Century Aluminum of West Virginia, Inc. (“CAWV”) amended its postretirement medical benefit plan for all current and former salaried employees, their dependents and all bargaining unit employees who retired before June 1, 2006, and their dependents. Effective January 1, 2011, CAWV no longer provided retiree medical benefits to active salaried CAWV personnel or any other personnel who retired prior to November 1, 2010. CAWV has made no commitments as to the future status of retiree medical benefits for hourly personnel who are currently covered by an active medical program. For those retirees impacted by the changes and who have elected COBRA coverage, CAWV waived COBRA premiums through June 30, 2011.
The November 1, 2010 plan amendments resulted in the immediate recognition of any unamortized prior service cost benefits that were accrued in other comprehensive income as of the date of the amendments. In addition, the November 1, 2010 plan amendments resulted in a reduction in OPEB liability and a credit to other comprehensive income. The newly established prior service benefit and actuarial losses were amortized ratably into income over the period November 1, 2010 to June 30, 2011 at which time the CAWV OPEB plan terminated.
With the ratification of the Hawesville labor agreement in December 2010, changes were made to the retiree medical benefits program for employees who retire during the term of the labor agreement. Such retirees have been divided into sub-groups based on attributes such as Medicare eligibility, hire date, age and years of service. Levels of benefits are defined for the sub-groups and range from no substantive change from the benefits provided under the previous labor agreement to replacement of the defined retiree medical benefit program with individual health reimbursement accounts for each eligible participant. The health reimbursement accounts will be funded by CAKY based at established rates per hour worked by each eligible participant. Eligible participants will be able to withdraw from their health reimbursement accounts to fund their own retiree medical coverage.

Effect of Medicare Part D
Century’s prescription drug programs are assumed to be actuarially equivalent and eligible for Medicare Part D subsidy as written into law in December 2003. The approach used to measure this impact is based on our understanding of ASC 715-60. We recognized the impact of these changes on a prospective basis. As of December 31, 2011, the effect of the Medicare Part D subsidy reduced the accumulated projected benefit obligation of our OPEB plans by $15,364, which is an approximate 11% decrease for our OPEB plans.
For measurement purposes, medical cost inflation is initially estimated to be 10%, declining to 5% over six years and thereafter.
Assumed health care cost trend rates have a significant effect on the amounts reported for the health care benefit obligations. A one-percentage-point change in the assumed health care cost trend rates would have had the following effects in 2011:

|  | 1% Increase |  |  | 1% Decrease |
Effect on total of service and interest cost |  | $ | 1,198 |  |  | $ | (977 | )
Effect on accumulated postretirement benefit obligation |  |  | 21,099 |  |  |  | (17,296 | )

Century 401(k) Plans
We sponsor a tax-deferred savings plan under which eligible domestic employees may elect to contribute specified percentages of their compensation with Century. In 2011, for our eligible employees, we reinstituted company matching for participants contributions to the savings plan. We suspended our company matching contributions to the 401(k) plan for 2010 and 2009. Employees are considered fully vested immediately upon participation in the plan.

Benefit Plan Assets
Pension Plan Investment Policy and Strategy
We have established the defined benefit pension plans (the “Pension Plans”) as a retirement vehicle for the plan participant employees and as a funding vehicle to secure promised benefits. The Pension Plans’ assets are invested in a prudent manner for the exclusive purpose of providing benefits to participants. Other objectives are to:

| · | Provide a total return that, over long term, provides sufficient assets to fund the pension plan liabilities.

| · | Maximize the return on assets, over the long term, by investing a majority of the Pension Plans’ assets in equities. The inclusion of additional asset classes with differing rates of return, volatility and correlation are utilized to reduce risk by providing diversification relative to equities.

| · | Diversify investments within asset classes to reduce the impact of losses in single investments.

The assets of the Pension Plans are invested in compliance with ERISA, as amended, and any subsequent applicable regulations and laws.

Performance
Our performance objective is to outperform the return on a weighted hypothetical portfolio return (the “Policy Portfolio”) after fees at a comparable level of risk. This investment objective is expected to be achieved over the long term and is measured over rolling multi-year periods. Peer-relative performance comparisons will also be considered especially when performance deviates meaningfully from market indexes. Investment objectives for each asset class are included below.
Policy Portfolio
Asset allocation policy is the principal method for achieving the Pension Plans and investment objectives stated above. The Plans’ long-term strategic asset allocation policy targets are as follows:

|  | Pension Plan Asset Allocation |
|  | Policy Target |  |  | December 31, 2011 |  |  | December 31, 2010 |
Equities: |  |  |  |  |  |  |  |  |
U.S. equities |  |  | 50 | % |  |  | 51 | % |  |  | 50 | %
International equities |  |  | 15 | % |  |  | 14 | % |  |  | 15 | %
Fixed income |  |  | 35 | % |  |  | 35 | % |  |  | 35 | %
|  |  |  |  |  |  | 100 | % |  |  | 100 | %

U.S. and international equities are held for their long-term expected return premium over fixed income investments and inflation. Fixed income is held for diversification relative to equities.
The strategic role of U.S. and international equities is to:

| · | Provide higher expected returns of the major asset classes.

| · | Maintain a diversified exposure within the U.S. and international stock markets through the use of multi-manager portfolio strategies.

| · | Achieve returns in excess of passive indexes through the use of active investment managers and strategies.

The strategic role of fixed income is to:

| · | Diversify the Pension Plans’ equity exposure by investing in fixed income securities that exhibit a low correlation to equities, thereby lowering the overall return volatility of the entire investment portfolio.

| · | Maintain a diversified exposure within the U.S. fixed income market through the use of multi-manager portfolio strategies.

| · | Achieve returns in excess of passive indexes through the use of active investment managers and strategies.

The long-term strategic asset allocation policy is reviewed regularly or whenever significant changes occur to Century’s or the Pension Plans financial position and liabilities.
Expected rate-of-return assumption
We are currently using an 8.0% long-term rate of return on plan assets for the development of the net periodic cost for the defined benefit pension plans.

Fair Value Measurements of Pension Plan Assets
ASC 820, “Fair Value Measurements, and Disclosures,” defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. This pronouncement applies to a broad range of other existing accounting pronouncements that require or permit fair value measurements. We measured the fair value of our Pension Plans’ assets in accordance with ASC 820. For additional information about fair value measurement, see Note 4 Fair Value Measurements.
The following table sets forth by level within the ASC 820 fair value hierarchy our Pension Plan assets. As required by generally accepted accounting principles for fair value measurements and disclosures, these assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and the placement within the fair value hierarchy levels. For additional information, see Note 4 Fair Value Measurements.

Fair Value of Pension Plans’ assets by category under the fair value hierarchy:

Our Pension Plans’ assets are held in certain investment fund trusts. The fair value of the fund trusts is based on the fair value of the underlying securities as determined as follows:

| · | U.S. listed equities; equity and fixed income options: Last sale price; last bid price if no last sale price;

| · | U.S. over-the-counter equities: Official closing price; last bid price if no closing price;

| · | Foreign equities: Official closing price, where available, or last sale price; last bid price if no official closing price; and

| · | Municipal bonds, US bonds, Eurobonds/foreign bonds: Evaluated bid price; broker quote if no evaluated bid price.

Our other postretirement benefit plans are unfunded. We fund these benefits as the retirees submit claims.

Participation in Multi-Employer Pension Plans
We contribute to one multiemployer defined benefit pension plan under the terms of a collective-bargaining agreement that covers our union-represented employees at Hawesville. Currently, we do not have any plans to withdraw from or curtail participation in this plan. The risks of participating in a multiemployer plan are different from single-employer plans in the following aspects:

| · | Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers.

| · | If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers.

| · | If a participating employer chooses to stop participating in a multiemployer plan, the employer may be required to pay the plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

The union-represented employees at Hawesville are part of a United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union (“USWA”) sponsored multi-employer plan. Our contributions to the plan are determined at a fixed rate per hour worked.

(1) | The most recent Pension Protection Act zone status available in 2011 and 2010 is for the plans’ year-end December 31, 2010 and December 31, 2009, respectively. The zone status is based on information that Century received from the plan as well as publicly available information per the Department of Labor and is certified by the plan’s actuary. Among other factors, plans in the red zone are generally less than 65 percent funded, plans in the yellow zone are less than 80 percent funded, and plans in the green zone are at least 80 percent funded.
(2) | The number of union-represented employees at Hawesville increased approximately 10% due to the restart of curtailed operations.
(3) | Our contributions to the Steelworkers Pension Trust are not 5% or more of the total contributions to the plan.

12. | Share Based Compensation

At the time three directors designated for nomination to our Board of Directors were elected in June 2011, it was determined a “change of control” occurred under the terms of our share-based incentive compensation plans. As a result, certain outstanding share-based incentive awards immediately vested and we recognized compensation expense for the accelerated vesting of these awards in 2011.
1996 Stock Incentive Plan — We award performance-based and service-based (time vested) share awards and grant qualified incentive and nonqualified stock options to our salaried officers, non-employee directors, and other key employees from our 1996 Stock Incentive Plan (the “Stock Incentive Plan”). The Stock Incentive Plan has 10,000,000 shares authorized for issuance with approximately 7,429,000 shares remaining at December 31, 2011. Granted stock options have a term of 10 years and typically vest one-third on the grant date and additional one-third on the first and second anniversary dates of the grant. Our independent non-employee directors receive annual grants of service-based share awards that vest following 12 months of service. In addition to the stock options, we grant service-based stock awards that typically vest over a period of three years from the date of grant provided that the recipient is still our employee at the time of vesting.
As of December 31, 2011, options to purchase 611,334 shares of common stock were outstanding and 347,191 service-based stock awards have been authorized, all awards granted prior to June 7, 2011 are vested and the remainder will vest if the employee recipients are employed for the requisite service periods.

Table of Contents
CENTURY ALUMINUM COMPANY
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)
The Stock Incentive Plan provides for grants of performance share units upon the attainment of certain established performance goals. The performance share units represent the right to receive common stock, on a one-for-one basis on their vesting dates. As of December 31, 2011, approximately 174,172 performance share units have been authorized, all awards granted prior to June 7, 2011 are vested and the remainder will vest upon the attainment of the performance goals. Under the performance share plan, a portion of the performance share award will be granted in service-based share awards at the grant date. These shares will be awarded to the plan participant if the participant is still an employee on the award date and are included in our service-based share awards.
Under our equity compensation program for our directors, continuing independent directors receive annual grants of service-based share awards. Newly elected directors receive a one-time initial award of 1,000 service-based share awards that vest 50% following 12 months of service and 50% following 24 months of service. These awards are included in our service-based share awards.
Non-Employee Directors Stock Option Plan — Our non-employee directors’ stock option plan is no longer an active plan. As of December 31, 2011, this plan had 21,000 outstanding options. No new options will be issued out of this plan.
A summary of activity under our Stock Incentive Plan and the Non-Employee Directors Stock Option Plan during the year ended December 31, 2011 is presented below:

Options |  | Number |  |  | Weighted Average Exercise Price |  | Weighted Average Remaining Contractual Term (years) | Aggregate Intrinsic Value

(1) | We recorded a net credit for service-based stock awards in 2010 due to adjustments to share-based expense for payroll taxes paid in cash during the year.

As of December 31, 2011, we had unrecognized compensation expense of $362 before taxes, related to service-based stock awards awarded after June 6, 2011. This expense will be recognized over a weighted average period of 0.50 years.
During 2011, employees and non-employee directors exercised 12,677 stock options; we received $83 in cash and did not recognize any tax benefits on these option exercises.
We issue new shares to satisfy the requirements of our share-based compensation plans. At this time, we do not plan to issue treasury shares to support our share-based compensation plans, but we may in the future.

13. | Earnings (Loss) Per Share

Basic earnings (loss) per share (“EPS”) amounts are calculated by dividing earnings available to common shareholders by the weighted average number of common shares outstanding. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive common shares outstanding. The following table shows the basic and diluted earnings (loss) per share for 2011 and 2010:

|  | For the year ended December 31, 2011 |
|  | Net income |  |  | Shares (000) |  |  | Per-Share |
Net income |  | $ | 11,325 |  |  |  |  |  |  |

Income applicable to common shareholders with assumed conversion |  | $ | 55,046 |  |  |  | 93,302 |  |  | $ | 0.59 |

During 2009, we reported net losses, so any dilutive common shares would be antidilutive to EPS. The following table shows the basic and diluted earnings (loss) per share for 2009:

|  | Net income (loss) |  |  | Shares (000) |  |  | Per-Share |

Impact of issuance of Series A Convertible Preferred Stock on EPS
Our Series A Convertible preferred stock has similar characteristics of a “participating security” as described by ASC 260-10-45. In accordance with the guidance in the ASC 260-10-45, we calculated basic EPS using the Two-Class Method, allocating undistributed income to our preferred shareholder consistent with their participation rights, and diluted EPS using the If-Converted Method when applicable.
ASC 260-10-50 does not require the presentation of basic and diluted EPS for securities other than common stock and the EPS amounts, as presented, only pertain to our common stock.
The Two-Class Method is an earnings allocation formula that determines earnings (loss) per share for common shares and participating securities according to dividends declared (or accumulated) and the participation rights in undistributed earnings. Our preferred stock is a non-cumulative perpetual participating convertible preferred stock with no set dividend preferences. See Note 7 Shareholders’ Equity for additional information about the rights and features of the preferred stock.
The holders of our convertible preferred stock do not have a contractual obligation to share in our losses. Thus, in periods where we report net losses, we do not allocate these losses to the convertible preferred stock for the computation of basic or diluted EPS.
For the calculation of basic and diluted EPS using the Two-Class Method in 2009, we did not allocate any of our undistributed net loss to the convertible preferred stock.
Calculation of EPS
For the period ended December 31, 2011, 632,334 options to purchase common stock and 347,191 service-based share awards were outstanding.
For the period ended December 31, 2010, 675,575 options to purchase common stock and 551,382 service-based share awards were outstanding.
For the period ended December 31, 2009, 692,075 options to purchase common stock and 501,203 service-based share awards were outstanding, but all options, service-based awards and shares to be issued upon the assumed conversion of our convertible debt were excluded from the calculation of diluted EPS because of their antidilutive effect on earnings per share.

(1) | These stock option awards were excluded from the calculation of diluted EPS because the exercise price of these options was greater than the average market price of the underlying common stock, except in years when we had a net loss where all options were excluded because of their antidilutive effect on earnings per share.
(2) | In periods in which our 1.75% Notes were outstanding, the average price for our common stock was below the conversion price of our 1.75% Notes.

Under ASC 740, “Accounting for Income Taxes”, a valuation allowance must be established when it is more likely than not that all or a portion of a deferred tax asset will not be realized. The amount of valuation allowance is based upon our best estimate of our ability to realize the net deferred tax assets. A valuation allowance can subsequently be reversed when we believe that the assets are realizable on a more likely than not basis. The valuation allowance increases are primarily due to U.S. and foreign operating income and losses generated in jurisdictions where a full valuation allowance has been recorded.
The changes in the valuation allowance are as follows:

|  | 2011 |  |  | 2010 |
Beginning balance, valuation allowance |  | $ | 714,423 |  |  | $ | 681,094 |

We have removed our election to permanently reinvest foreign earnings for 2011, 2010, and 2009. The cumulative amount of foreign undistributed net earnings for which no deferred taxes have been provided was $159,087 at December 31, 2011. Management has no plans to distribute such earnings in the foreseeable future.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Included in the above balances are tax positions whose tax characterization is highly certain but for which there is uncertainty about the timing of tax return inclusion. Because of the impact of deferred tax accounting, other than interest and penalties, the timing would not impact the annual effective tax rate but could accelerate the payment of cash to the taxing authority to an earlier period. The remaining amounts of unrecognized tax benefits would affect our effective tax rate if recognized. It is our policy to recognize potential accrued interest and penalties related to unrecognized tax benefits in income tax expense.

Century and its subsidiaries file income tax returns in the U.S. federal jurisdiction, various state and local jurisdictions, and several foreign jurisdictions.
Our federal income tax returns beginning in 2008 are subject to examination. Our 2008 tax year is currently under audit by the Internal Revenue Service (“IRS”). Additionally, a 2005 amended return is also under audit with respect to carry back items. Material state and local income tax matters have been concluded for years through 2002. The majority of our other state returns beginning in 2005 are subject to examination. Our Icelandic tax returns are subject to examination beginning with the 2005 tax year.
We do not expect a significant change in the balance of unrecognized tax benefits within the next twelve months.

15. | Commitments and contingencies

Environmental Contingencies
Based upon all available information, we believe our current environmental liabilities do not have, and are not likely to have, a material adverse effect on our financial condition, results of operations or liquidity. Because of the issues and uncertainties described below and the inability to predict the requirements of future environmental laws, there can be no assurance that future capital expenditures and costs for environmental compliance at currently or formerly owned or operated properties will not result in liabilities which may have a material adverse effect.
It is our policy to accrue for costs associated with environmental assessments and remedial efforts when it becomes probable that a liability has been incurred and the costs can be reasonably estimated. The aggregate environmental-related accrued liabilities were $852 and $753 at December 31, 2011 and 2010, respectively. All accrued amounts have been recorded without giving effect to any possible future recoveries. With respect to costs for ongoing environmental compliance, including maintenance and monitoring, such costs are expensed as incurred.

In July 2005, the Environmental Protection Agency (“EPA”) began an initiative to perform an oversight inspection of all Secondary Maximum Achievable Control Technology (“MACT”) facilities which deal with casting furnaces, including Hawesville. Partial inspections were also conducted at collocated Primary MACT facilities which deal with potlines, including Hawesville. In November 2009, the EPA sent CAKY a Notice of Violation (“NOV”) alleging 12 violations relating to the Clean Air Act including, among other things, violations of the MACT emissions standards and the prevention of significant deterioration program for unpermitted major modifications. The number of alleged violations was ultimately reduced to two, and in August 2011, we reached a settlement with the EPA to resolve such remaining violations and paid a $178 fine related to this matter.
Century Aluminum of West Virginia, Inc. (“CAWV”) continues to perform remedial measures at Ravenswood pursuant to an order issued by the EPA in 1994 (the “3008(h) Order”). CAWV also conducted a RCRA facility investigation (“RFI”) under the 3008(h) Order evaluating other areas at Ravenswood that may have contamination requiring remediation. The RFI has been approved by appropriate agencies. CAWV has completed interim remediation measures at two sites identified in the RFI, and we believe no further remediation will be required. A Corrective Measures Study, which formally documents the conclusion of these activities, has been submitted by the EPS for a final order.
Prior to our purchase of Hawesville, the EPA issued a final Record of Decision (“ROD”) under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (“CERCLA”). By agreement, Southwire Company (“Southwire”), the former owner and operator is to perform all obligations under the ROD. CAKY has agreed to operate and maintain the ground water treatment system required under the ROD on behalf of Southwire, and Southwire will reimburse CAKY for any expense that exceeds $400 annually.
In July 2006, we were named as a defendant, together with certain affiliates of Alcan Inc., in a lawsuit brought by Alcoa Inc. seeking to determine responsibility for certain environmental indemnity obligations related to the sale of a cast aluminum plate manufacturing facility located in Vernon, California, which we purchased from Alcoa Inc. in December 1998, and sold to Alcan Rolled Products-Ravenswood LLC in July 1999. The complaint also seeks costs and attorney fees. At this time, it is not practicable to predict the ultimate outcome of these actions or to estimate a range of possible damage awards.
Matters relating to the St. Croix Alumina Refining Facility
We are a party to an EPA Administrative Order on Consent (the “Order”) pursuant to which other past and present owners of an alumina refining facility at St. Croix, Virgin Islands (the “St. Croix Alumina Refinery”) have agreed to carry out a Hydrocarbon Recovery Plan to remove and manage hydrocarbons floating on groundwater underlying the facility. Pursuant to the Hydrocarbon Recovery Plan, recovered hydrocarbons and groundwater are delivered to the adjacent petroleum refinery where they are received and managed. In connection with the sale of the facility by Lockheed Martin Corporation (“Lockheed”), to one of our affiliates, Virgin Islands Alumina Corporation (“Vialco”), in 1989, Lockheed, Vialco and Century entered into the Lockheed-Vialco Asset Purchase Agreement. The indemnity provisions contained in the Lockheed-Vialco Asset Purchase Agreement allocate responsibility for certain environmental matters. Lockheed has tendered indemnity and defense of the above matter to Vialco. We have likewise tendered indemnity to Lockheed. Through December 31, 2011, we have expended approximately $840 on the Hydrocarbon Recovery Plan. We expect the future potential payments under this indemnification to comply with the Order will be approximately $500, which may be offset in part by sales of recoverable hydrocarbons.

In May 2005, we and Vialco were among several defendants listed in a lawsuit filed by the Commissioner of the Department of Planning and Natural Resources (“DPNR”), in his capacity as Trustee for Natural Resources of the United States Virgin Islands. The complaint alleges damages to natural resources caused by alleged releases from the St. Croix Alumina Refinery and the adjacent petroleum refinery. The primary cause of action is pursuant to the natural resource damage provisions of CERCLA, but various ancillary Territorial law causes of action were included as well. We and Lockheed have each tendered indemnity and defense of the case to the other pursuant to the terms of the Lockheed-Vialco Asset Purchase Agreement. The complaint seeks unspecified monetary damages, costs and attorney fees. We and Vialco have filed answers to the complaint asserting factual and affirmative defenses. In November 2011, the court granted a motion by Century, dismissing Century from the case. Vialco, however, remains a defendant in this case. The parties are currently engaged in the discovery process. As of December 31, 2011, no trial date has been set for the remaining claims.
In December 2006, Vialco and the two succeeding owners of the St. Croix Alumina Refinery were named as defendants in a lawsuit filed by the Commissioner of the DPNR. The complaint alleges the defendants failed to take certain actions specified in a Coastal Zone management permit issued to Vialco in October 1994, and alleges violations of territorial water pollution control laws during the various defendants’ periods of ownership. The complaint seeks statutory and other unspecified monetary penalties for the alleged violations. The parties are currently engaged in the discovery process.
In May 2009, St. Croix Renaissance Group, L.L.L.P. (“SCRG”) filed a third-party complaint for contribution and other relief against several third-party defendants, including Vialco, relating to a lawsuit filed against SCRG seeking recovery of response costs relating to the aforementioned DPNR CERCLA matter. In February 2011, the court granted a motion by Century, dismissing Century from the case. Vialco, however, remains a defendant in this case. In March 2011, the court granted the remaining defendants’, including Vialco’s, motion for summary judgment, dismissing the case. The plaintiff filed a notice of appeal with the Third Circuit Court of Appeals in May 2011. The appeal is set for hearing in May 2012.
In December 2010, Century was among several defendants listed in a lawsuit filed by approximately 2,300 plaintiffs who either worked, resided or owned property in the area downwind from the St. Croix Alumina Refinery. In March 2011, Century was also named a defendant in a nearly identical suit brought by approximately 200 plaintiffs previously named in the aforementioned suit. The plaintiffs in both suits allege damages caused by the presence of red mud and other particulates coming from the alumina facility. The plaintiffs in both suits seek unspecified monetary damages, costs and attorney fees as well as certain injunctive relief. We have tendered indemnity and defense to St. Croix Alumina LLC and Alcoa Alumina & Chemical LLC under the terms of an acquisition agreement relating to the facility and have filed a motion to dismiss plaintiffs’ claims, but the court has not yet ruled on the motion.
Pursuant to the terms of the asset purchase agreement between Vialco and the purchaser of the St. Croix Alumina Refinery in 1995, the purchaser assumed responsibility for all costs and other liabilities associated with the bauxite waste disposal facilities, including pre-closure and post-closure liabilities. At this time, it is not practicable to predict the ultimate outcome of or to estimate a range of possible losses relating to any of the foregoing actions.
Legal Contingencies
We have pending against us or may be subject to various lawsuits, claims and proceedings related primarily to employment, commercial, environmental, shareholder, safety and health matters. Although it is not presently possible to determine the outcome of these matters, management believes their ultimate disposition will not have a material adverse effect on our financial condition, results of operations, or liquidity.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)
In evaluating whether to accrue for costs associated with legal contingencies, it is our policy to take into consideration factors such as the facts and circumstances asserted, our historical experience with contingencies of a similar nature, the likelihood of our prevailing and the severity of any potential loss. For some matters, no accrual is established because we have assessed our risk of loss to be remote. Where the risk of loss is probable and the costs can be reasonably estimated, we record an accrual, either on an individual basis or with respect to a group of matters involving similar claims, based on the factors set forth above.
We also determine estimates of reasonably possible losses or ranges of reasonably possible losses in excess of related accrued liabilities, if any, when we have assessed that a loss is reasonably possible. Based on current knowledge, management has ascertained estimates for losses that are reasonably possible and management does not believe that any reasonably possible outcomes in excess of our accruals, if any, would be material. We reevaluate and update our assessments and accruals as matters progress over time.
In November 2011, we were named as a defendant in a lawsuit filed by our former Chief Executive Officer, Logan Kruger, alleging breach of contract and wrongful termination in violation of public policy. The lawsuit alleges that Century anticipatorily breached the employment and severance protection agreements between Century and Mr. Kruger and that Century is obligated to make various severance payments in excess of $20,000 to Mr. Kruger under such agreements. In addition, the complaint seeks unspecified damages, including exemplary and punitive damages, for wrongful termination, as well as costs and attorneys’ fees. We believe these claims are without merit and intend to vigorously defend our self against them. The matter is in a preliminary stage, and we cannot predict the ultimate outcome of this action or estimate a range of possible losses related to this matter at this time.
In March 2011, the purported stockholder class actions pending against us consolidated as In re: Century Aluminum Company Securities Litigation were dismissed with prejudice by the United States District Court for the Northern District of California. The plaintiffs in the class actions allege that we improperly accounted for cash flows associated with the termination of certain forward financial sales contracts which accounting allegedly resulted in artificial inflation of our stock price and investor losses. Plaintiffs are seeking rescission of our February 2009 common stock offering, unspecified compensatory damages, including interest thereon, costs and expenses and attorneys’ fees. On March 10, 2011, plaintiffs filed a notice of appeal to the order and judgment entered by the court on March 3, 2011. The notice of appeal remains pending before the U.S. Court of Appeals for the Ninth Circuit.
Ravenswood Retiree Medical Benefits changes
Century Aluminum of West Virginia, Inc. (“CAWV”) amended its postretirement medical benefit plan, effective January 1, 2010, for all current and former CAWV salaried employees, their dependents and all bargaining unit employees who retired before June 1, 2006, and their dependents. Effective January 1, 2011, CAWV no longer provided retiree medical benefits to active salaried CAWV personnel or any other personnel who retired prior to November 1, 2010.
The principal changes to the plan as a result of this amendment were that, upon attainment of age 65, all CAWV provided retiree medical benefits ceased for retirees and dependents. In addition, bargaining unit retirees under age 65 and qualified dependents under age 65 were covered by the salary retiree medical plan which required out-of pocket payments for premiums, co-pays and deductibles by participants.

In November 2009, CAWV filed a class action complaint for declaratory judgment against the USWA, the USWA’s local union, and four CAWV retirees, individually and as class representatives, seeking a declaration of CAWV’s rights to modify/terminate retiree medical benefits as described above. Later in November 2009, the USWA and representatives of a retiree class filed a separate suit against CAWV, Century Aluminum Company, Century Aluminum Master Welfare Benefit Plan, and various John Does with respect to the foregoing. These actions, entitled Dewhurst, et al. v. Century Aluminum Co., et al., and Century Aluminum of West Virginia, Inc. v. United Steel, Paper and Forestry, Rubber Manufacturing, Energy, Allied Industrial & Service Workers International Union, AFL-CIO/CLC, et al., have been consolidated and venue has been set in the District Court for the Southern District of West Virginia.
In January 2010, the USWA filed a motion for preliminary injunction to prevent us from implementing the foregoing changes while these lawsuits are pending, which was dismissed by the trial court. In August 2011, the Fourth Circuit Court of Appeals upheld the District Court’s dismissal of the USWA’s motion for preliminary injunction, finding that the USWA had failed to establish the likelihood of success on the merits of the underlying matter. Based upon our analysis of the court’s ruling during the third quarter of 2010, in accordance with ASC 715-60, “Compensation – Retirement Plans – Defined Benefit Plans – Other Postretirement”, the amendment to the CAWV postretirement medical plan benefits was recorded as a negative plan amendment in the third quarter of 2010. In October 2011, CAWV filed a motion to dismiss plaintiff’s first amended complaint with the trial court. No ruling has yet been made on the motion. We intend to continue to vigorously pursue our case in the foregoing actions.
Power Commitments
Hawesville
The Big Rivers Agreement has a term through December 2023, unless extended. The Big Rivers Agreement is a cost-based agreement that provides sufficient power for Hawesville’s full production capacity requirements. The Big Rivers Agreement is take-or-pay for Hawesville’s energy requirements at full production. In November 2011, the Kentucky Public Service Commission approved portions of a rate increase that had been previously proposed by Big Rivers. Both CAKY and Big Rivers have filed notice of appeals with respect to the rate increase. In addition Big Rivers filed a petition for rehearing with the Commission. This petition and both appeals are still pending. The rate increase became effective as of September 1, 2011.
Mt. Holly
Mt. Holly has a power purchase agreement (the “Santee Cooper Agreement”) with the South Carolina Public Service Authority (“Santee Cooper”) with a term through December 2015, unless extended. The Santee Cooper Agreement provides adequate power for Mt. Holly’s full production capacity requirements at prices fixed based on published rate schedules (which are subject to change), with adjustments for fuel prices and other items. The Santee Cooper Agreement restricts Mt. Holly’s ability to reduce its power consumption (or the associated payment obligations) below contracted levels and to terminate the agreement, unless, in each case, the LME falls below certain negotiated levels.
Ravenswood
CAWV has a power purchase agreement (the “ApCo Agreement”) with the Appalachian Power Company (“ApCo”) with a term through June 2012, unless extended. CAWV currently purchases a limited amount of power under the ApCo Agreement as necessary to maintain its Ravenswood smelter, which is presently curtailed. Power is supplied under the ApCo Agreement at prices set forth in published tariffs (which are subject to change), with certain adjustments. Under the special rate contract, Ravenswood may be excused from, or may defer the payment of, any increase in the tariff rate if LME prices fall below certain negotiated levels. CAWV is in discussions with APCo to provide for a long-term special rate arrangement that establishes the LME-based cap on the tariff rates.

Grundartangi
Nordural Grundartangi ehf has power purchase agreements with HS Orka hf (“HS”), Landsvirkjun and Orkuveita Reykjavikur (“OR”) to provide power to its Grundartangi smelter. These power purchase agreements, which will expire on various dates from 2019 through 2036, provide power at LME-based variable rates. Each power purchase agreement contains take-or-pay obligations with respect to a significant percentage of the total committed and available power under such agreement.
Helguvik
Nordural Helguvik ehf has power purchase agreements with HS and OR to provide power to the Helguvik project. These power purchase agreements provide power at LME-based variable rates and contain take-or-pay obligations with respect to a significant percentage of the total committed and available power under such agreements. The first stage of power under the OR power purchase agreement (approximately 47.5 MW) became available in the fourth quarter of 2011 and is being utilized at Grundartangi until the first stage of the Helguvik project has been completed. No other power is currently available under either power purchase agreement. HS (with respect to all phases) and OR (with respect to all phases other than the first phase) have alleged that certain conditions to the delivery of power under the power purchase agreements have not been satisfied. Nordural Helguvik is in discussion with both HS and OR with respect to such conditions.
Other Commitments and Contingencies
Labor Commitments
Approximately 75% of our U.S. based work force is represented by the USWA. CAKY’s Hawesville plant employees represented by the USWA are under a collective bargaining agreement which expires on March 31, 2015.
In April 2010, Nordural Grundartangi ehf entered into a new labor agreement with the five labor unions representing approximately 84% of Grundartangi’s work force. The labor agreement expires on December 31, 2014.
CAWV’s Ravenswood plant employees represented by the USWA are under a labor agreement that expired on August 31, 2010. Negotiations for a new labor agreement are ongoing.
Other Commitments
The Patient Protection and Affordable Care Act and the related Health Care and Education Reconciliation Act were enacted in March 2010. The Health Care Acts extend health care coverage to many uninsured individuals and expands coverage to those already insured. The Health Care Acts contain provisions which could impact our retiree medical benefits in future periods. However, the extent of that impact, if any, cannot be determined until regulations are promulgated under the Health Care Acts and additional interpretations of the Health Care Acts become available. We are continuing to assess the potential impacts that this legislation may have on our future results of operations, cash flows and financial position related to our health care benefits and other postemployment benefit obligations. Among other things, the Health Care Acts will eliminate the tax deductibility of the Medicare Part D subsidy for companies that provide qualifying prescription drug coverage to retirees effective for years beginning after December 31, 2012.

Non-Cash Activities
We incurred a $13,091 contingent obligation to E.ON for payments made above an agreed amount on CAKY’s behalf in excess of the amount agreed to in the Big Rivers Agreement in 2010. See Note 6 Debt for additional information about the E.ON contingent obligation.
Due to the curtailment of our Ravenswood operations in February 2009, we reclassified certain inventory items into other assets. As a result, there was an $18,023 non-cash change in the inventory due to this reclassification.
In 2011, 2010 and 2009, we issued shares of common stock to certain key employees to satisfy performance share liabilities of $0, $1,050 and $694, respectively, as part of our performance share program.

21. | Related Party Transactions

The significant related party transactions occurring during the years ended December 31, 2011, 2010 and 2009 are described below.
Sales to Glencore
We sold primary aluminum and alumina to Glencore both at spot and long-term contract basis. See Note 20 Business Segments for additional information about the sales of primary aluminum to Glencore.
We sold primary aluminum under our long-term sales contracts with Glencore at prices based on the LME price for primary aluminum, as adjusted to reflect the Midwest Premium (a premium typically added for deliveries of aluminum within the U.S.). In addition, we received tolling fees from Glencore under tolling agreements that provide for delivery of primary aluminum produced at Grundartangi. The fee paid by Glencore under these tolling agreements is based on the LME price for primary aluminum, as adjusted to reflect the reduced European Union import duty paid on Icelandic primary aluminum. We believe that all of the transactions with Glencore under these contracts were at prices that approximate market.
We have a long-term contract to sell Glencore primary aluminum, at a variable price based on the LME, adjusted by a negotiated U.S. Midwest market premium with a cap and floor as applied to the current U.S. Midwest Premium. In addition, we entered into a one-year contract through December 31, 2012 to sell Glencore all U.S. produced primary aluminum, less existing sales agreements and high-purity metal sales. The term of the contract may be extended upon mutual agreement. See Note 16 Forward contracts and financial instruments for additional information about our forward physical delivery contracts and tolling agreements with Glencore.
Purchases from Glencore
We purchased alumina from Glencore on both a spot and long-term contract basis. We believe that all of the alumina purchased under these long-term contracts was purchased at prices which approximated market. For alumina purchased from Glencore on a spot basis, we determined the market price for the spot alumina we purchased based on a survey of suppliers at the time that had the ability to deliver spot alumina on the specified terms. Based on this survey, we believe that all of the alumina purchased on a spot basis from Glencore was purchased at prices that approximate market.
In 2010, we entered into an agreement to buy alumina from Glencore for Grundartangi. Glencore agreed to supply us with 18,000 metric tons of alumina in 2010 at a fixed price. Based on a survey of suppliers at the time that had the ability to deliver spot alumina on the specified terms, we believe that the alumina purchased from Glencore under this contract was purchased at prices that approximate market.
Alumina contract and amendments. We are party to a long-term alumina supply agreement with Glencore. Glencore agreed to supply us with alumina through 2014 at prices indexed to the LME price of primary aluminum.
In April 2009, Glencore agreed to amend two alumina purchase agreements to reduce the amount of alumina Glencore supplied in 2009 and 2010, for an overall alumina supply reduction of 280,000 metric tons.

Primary aluminum put options
In 2011, 2010 and 2009, we entered into primary aluminum put option contracts with Glencore. We paid cash premium to enter into these contracts and recorded a short-term asset in due from affiliates on the consolidated balance sheets. We determined the fair value of the put options using a Black Scholes pricing model with inputs obtained from an independent source and account for the put options as derivative financial instruments with gains and losses in the fair value of the contracts recorded on the consolidated statements of operations in net losses on forward contracts. See Note 5 Derivative and hedging activities for additional information about the put option contracts.
Other Transactions with Glencore
As of December 31, 2011, we believe that Glencore beneficially owned, through its common stock, approximately 41.6% of our issued and outstanding common stock and, through its ownership of common and preferred stock, an overall 46.4% economic ownership of Century.
Transactions with BHH
We own a 40% stake in BHH, a carbon anode and cathode facility located in the Guangxi Zhuang Autonomous Region of south China. We have a long-term agreement with BHH to provide carbon anodes to Grundartangi through December 31, 2012. This agreement is renewable through December 31, 2015.
Summary
A summary of the aforementioned related party transactions for the years ended December 31, 2011, 2010 and 2009 is as follows:

|  | Year Ended December 31, |

22. | Investment in Unconsolidated 50% or Less Owned Joint Ventures

In April 2008, we entered into a joint venture agreement whereby we acquired a 40% stake in BHH, a carbon anode and cathode facility located in the Guangxi Zhuang Autonomous Region of south China. We also have a 50% interest in Mincenco, a joint venture with Minmetals Aluminum Company to explore the potential of developing a bauxite mine and associated 1.5 million metric ton alumina refining facility in Jamaica. We account for our investments in BHH and Mincenco using the equity method and the investments are included in other assets in the Consolidated Balance Sheets. For BHH, we report our investment in its results of operations on a one-quarter lag. For each year presented in our Consolidated Statement of Operations, our equity in earnings of joint venture includes BHH results of operations for a twelve month period ended on September 30 of that year.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

Not applicable.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

As of December 31, 2011, we carried out an evaluation, under the supervision and with the participation of our management, including our Acting Chief Executive Officer and the Chief Financial Officer, of the effectiveness of our disclosure controls and procedures. Based upon that evaluation, our management, including the Acting Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective.

Internal Control over Financial Reporting

Management is responsible for establishing and maintaining an adequate system of internal controls over financial reporting for the company. This system is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, a system of internal controls over financial reporting can provide only reasonable assurance and may not prevent or detect misstatements. Further, because of changes in conditions, effectiveness of internal controls over financial reporting may vary over time. Our system of internal controls contains self-monitoring mechanisms, and actions are taken to correct deficiencies as they are identified.
As required by Section 404 of the Sarbanes-Oxley Act, management conducted an evaluation of the effectiveness of the system of internal controls over financial reporting for the year ended December 31, 2011. Management’s evaluation was based on the framework in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations (COSO) of the Treadway Commission. Based on this evaluation, management concluded that our system of internal controls over financial reporting was effective as of December 31, 2011. The effectiveness of our internal control over financial reporting has been audited by Deloitte & Touche LLP, an independent registered public accounting firm.
Changes in Internal Control over Financial Reporting
During the quarter ended December 31, 2011, there have not been any changes in our internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
