PART I
Throughout this Annual Report on Form 10-K, and unless expressly stated otherwise or as the context otherwise requires, "Century Aluminum Company," "Century Aluminum," "Century," the "Company," "we," "us," and "our" refer to Century Aluminum Company and its subsidiaries.
Item 1.  Business.
Overview
Century Aluminum Company is a global producer of primary aluminum and operates aluminum reduction facilities, or "smelters," in the United States and Iceland.  We operate three U.S. aluminum smelters, in Hawesville, Kentucky ("Hawesville"), Robards, Kentucky ("Sebree") and Mt. Holly, South Carolina ("Mt. Holly"), and one smelter in Grundartangi, Iceland ("Grundartangi"). We also own an aluminum reduction facility in Ravenswood, West Virginia ("Ravenswood"), the operations of which have been curtailed since 2009, and have commenced construction on a new aluminum reduction facility in Helguvik, Iceland ("Helguvik" or the "Helguvik project"), construction of which is currently curtailed.
Primary 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 annual primary aluminum production capacity is approximately 1,166,000 tonnes per year ("tpy"), of which 170,000 tpy remained curtailed as of December 31, 2014.  We produced approximately 881,000 tonnes of primary aluminum in 2014.
In addition to our primary aluminum assets, we also own, through our wholly-owned subsidiary Century Aluminum Vlissingen B.V. ("Century Vlissingen"), a carbon anode production facility located in Vlissingen, the Netherlands ("Vlissingen") and hold a 40% interest in Baise Haohai Carbon Co., Ltd. ("BHH"), a joint venture that owns and operates a carbon anode and cathode facility located in the Guangxi Zhuang Autonomous Region of south China. Carbon anodes are used in the production of primary aluminum and both BHH and Vlissingen currently supply carbon anodes to Grundartangi.
We operate our business through one reportable segment, primary aluminum.  Additional information about our segment reporting and certain geographic information is available in Note 20, "Business segments" to the consolidated financial statements included herein.
Century Aluminum Company is a Delaware corporation with principal executive offices located at One South Wacker Drive, Suite 1000, Chicago, Illinois 60606.

(2)
Production at Grundartangi has increased by approximately 12,000 tonnes as a result of an ongoing 40,000 tpy expansion project that began in 2012.
(3)
In December 2014, we acquired the remaining 50.3% ownership stake in the Mt. Holly facility and now own 100% of the facility. 
(4)
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 an expectation of higher long-term LME prices, negotiation of a competitive power agreement, passage of supporting legislation and a new labor agreement.
(5)
The Helguvik project is expected to have a rated production capacity of up to 360,000 tpy.  During 2014, project activity and spending remained at modest levels.  We currently expect to restart major construction activity upon successful resolution of ongoing discussions with the contracted power suppliers for the project or procurement of another cost-effective source of power.  See "Electrical Power Supply Agreements."
Grundartangi
The Grundartangi facility, located in Grundartangi, Iceland, is a primary aluminum reduction facility owned and operated by our wholly-owned subsidiary, Nordural Grundartangi ehf.  Grundartangi is our most modern and lowest cost facility. Operations began in 1998 and production capacity has expanded significantly since that time to its current annual production capacity of approximately 298,000 tonnes. Grundartangi is currently in the process of a multi-year expansion project that is expected to ultimately increase production capacity at the smelter by approximately 40,000 tpy in the aggregate.  Grundartangi produces standard-grade aluminum and in 2014 began production of a foundry alloy product, which is a value-added product that is sold at a premium to standard-grade. We currently expect foundry alloy to account for approximately 50,000 tpy of our total production capacity at Grundartangi in 2015.
Grundartangi operates under various long-term permits and agreements with the Government of Iceland, local municipalities and Faxafloahafnir sf (which operates the harbor at Grundartangi and is jointly owned by several municipalities).  Grundartangi is currently in the process of expanding its operating permit for aluminum production to accommodate its current expansion project.   
Hawesville 
Hawesville, located adjacent to the Ohio River near Hawesville, Kentucky, is a primary aluminum reduction facility owned and operated by our wholly-owned subsidiary, Century Kentucky, Inc. ("CAKY").  Hawesville has an annual production capacity of approximately 252,000 tonnes.
Hawesville is our largest U.S. smelter and the largest producer of high purity primary aluminum in North America. Four of Hawesville's five potlines are specially configured and operated to produce high purity primary aluminum. 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 is also capable of providing high-conductivity metal used in electrical wire and cable products as well as for certain aerospace applications. Hawesville delivers a significant portion of its products in molten form to its customers.
Sebree 
Sebree, located adjacent to the Green River near Robards, Kentucky, is a primary aluminum reduction facility owned and operated by our wholly-owned subsidiary, Century Aluminum Sebree LLC ("Century Sebree"). Sebree began operations in 1973 and was acquired by Century in 2013. Sebree has an annual production capacity of approximately 215,000 tonnes.
Sebree produces standard-grade aluminum that is cast into several products, such as billet, foundry, slab and sow. In 2014, we also began production of a small form foundry line that we expect to account for approximately 35,000 tpy of our total production capacity at Sebree in 2015. Billet, foundry and slab are value-added primary aluminum products and are sold at a premium to sow. More than half of Sebree's production is cast into billet, which is primarily used by extruders and the automotive industry.

Mt. Holly
Mt. Holly, located in Goose Creek, South Carolina, is a primary aluminum reduction facility owned and operated by our wholly-owned subsidiary, Century Aluminum of South Carolina, Inc. ("CASC"). Mt. Holly was built in 1980 and is the most recently constructed aluminum reduction facility in the United States. Mt. Holly was operated as a joint venture between us and Alumax of South Carolina Inc. ("Alumax of SC") until our wholly-owned subsidiary, Berkeley Aluminum, Inc. ("Berkeley"), acquired Alumax of SC in December 2014. More information on the acquisition is available in Note 2 "Business acquisitions" to the consolidated financial statements included herein.
Mt. Holly has an annual production capacity of approximately 231,000 tonnes. Mt. Holly produces standard-grade aluminum that is cast into tee bars as well as several value-added products, including billet and foundry products. These value-added primary aluminum products are sold at a premium to standard-grade primary aluminum.  
Ravenswood
The Ravenswood facility, located adjacent to the Ohio River near Ravenswood, West Virginia, is owned and operated by our wholly-owned subsidiary, Century Aluminum of West Virginia, Inc. ("CAWV").  Built in 1957, Ravenswood has a rated annual production capacity of approximately 170,000 tonnes.  
In February 2009, we conducted an orderly curtailment of the plant operations at Ravenswood.  We continue to evaluate a possible restart of our idled Ravenswood smelter subject to market conditions and the achievement of other objectives, including a competitively priced power arrangement and a new labor agreement.
We continue to engage in discussions with Appalachian Power Company ("APCo") and other stakeholders.  Until those discussions have progressed further it is not possible to predict when or if a restart of the plant might occur.
Helguvik project
The Helguvik project site is located approximately 30 miles from the city of Reykjavik, Iceland and is owned through our wholly-owned subsidiary, Nordural Helguvik ehf.  
We commenced construction of the Helguvik project in June 2008.  In late 2008, we significantly reduced construction activity and spending on the project in response to the global financial crisis and deterioration of Icelandic economic and political conditions, including the financial condition of our contracted power suppliers.  Capitalized costs for the project through December 31, 2014 were approximately $148 million. Construction activity and spending on the project remain significantly curtailed pending confirmation from the contracted power suppliers or potentially other power suppliers that they will deliver the required power per an agreed schedule.  See "Supply Contracts – Electrical Power Supply Agreements" below for further discussion of our power arrangements at Helguvik.  
We currently expect to restart construction activity at Helguvik upon successful resolution of the power supply issues.  See Item 1A, "Risk Factors – Construction at our Helguvik smelter site has been significantly curtailed.  Substantial delay in the completion of this project may increase its cost, subject us to losses 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."
In connection with the construction of the Helguvik project, we have entered into an investment agreement with the Government of Iceland governing, among other things, the fiscal regime associated with the project and including a commitment by the Government of Iceland to assist us in obtaining necessary regulatory approvals for completion of the Helguvik project.  We have also entered into a transmission agreement with the national transmission company, Landsnet hf ("Landsnet"), to provide an electrical power transmission system to the Helguvik project. We have also entered into a site and harbor agreement, as well as technology and equipment supply agreements with respect to the Helguvik project.
We have received a positive opinion from the Icelandic Planning Agency on the Environmental Impact Assessment for the proposed Helguvik smelter as well as an Operating License enabling production of up 250,000 tpy.

Vlissingen
Vlissingen, located in Vlissingen, the Netherlands, is a carbon anode production facility owned and operated by Century Vlissingen. Century purchased the facility in June 2012. Production at Vlissingen, which had been curtailed by its previous owner, was restarted in late 2013 with an initial annual carbon anode production capacity of 75,000 tonnes. In the third quarter of 2014, we began a project to restart the second baking furnace, which is expected to increase total annual production capacity to 150,000 tonnes. The project is currently expected to be completed by the end of 2015.
Baise Haohai Carbon Company, Ltd.
BHH is a carbon anode and cathode facility located in the Guangxi Zhuang Autonomous Region of south China. The facility began operations in 2008. BHH is operated as a joint venture between one of our wholly-owned subsidiaries, which owns a 40% stake in the company, and Guangxi Qiangqiang Carbon Co., Ltd., which holds the remaining 60% ownership interest and is the operator of this facility. The BHH facility has a carbon anode production capacity of 180,000 tpy and a cathode baking and graphitization capacity of 20,000 tpy.  
Pricing
Generally, we price our products at a "market" price, in which the customer pays a regional delivery premium over the LME price, plus any value-added product premiums. Our operating results are highly sensitive to changes in the LME price of primary aluminum and the value of regional delivery and product premiums, as well as the cost of electrical power, raw materials and other operating supplies used in production.  As a result, from time to time, we assess the appropriateness of mitigating the effects of fluctuations in these items through the use of various fixed-price commitments and financial instruments.
Customer Base
For the year ended December 31, 2014, we derived approximately 77% of our consolidated sales from our two major customers: Glencore plc (together with its subsidiaries, "Glencore") and Southwire Company ("Southwire").    
Hawesville supplied approximately 98,000 tonnes of primarily high-conductivity molten aluminum to Southwire’s adjacent wire and cable manufacturing facility in 2014. The price for aluminum delivered to Southwire was variable and determined by reference to the LME price for primary aluminum, plus the Midwest regional delivery premium (the "Midwest Transaction Price") plus additional product premiums. Our metal sales agreement with Southwire expired at the end of 2014.
Pursuant to several agreements with Glencore, we expect to sell substantially all of our production to Glencore in 2015. With respect to Century’s Icelandic production, Grundartangi has entered into an aluminum supply agreement with Glencore pursuant to which Glencore will purchase substantially all primary aluminum produced at Grundartangi from 2014 through 2017 at market prices, less commitments under existing tolling contracts (the "Glencore Grundartangi Metal Agreement").  The price for aluminum delivered to Glencore is determined by reference to the LME price for primary aluminum, plus the European Duty Paid premium and any applicable product premiums. Grundartangi sold to Glencore approximately 155,000 tonnes of aluminum under this agreement in 2014 and currently estimates that it will sell Glencore approximately 205,000 tonnes in 2015. Grundartangi also has a long-term tolling agreement with Glencore for 90,000 tpy through July 2016.  Under this agreement, Glencore provides Grundartangi alumina and receives primary aluminum in return for tolling fees that are

6


based on the price of primary aluminum.  With respect to its North American production, Century has entered into an aluminum supply agreement with Glencore pursuant to which Glencore will purchase substantially all of our primary aluminum production in North America in 2015 and 2016 at market prices determined by reference to the Midwest Transaction Price plus additional product premiums.
Additional information about the revenues from these major customers is available in Note 20, "Business segments" to the consolidated financial statements included herein.
Energy, Key Supplies and Raw Materials
We consume the following key supplies, energy and raw materials in the primary aluminum reduction process:
 
electrical power
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 75% of our cost of goods sold for the year ended December 31, 2014.  We have long-term contracts to attempt to ensure the future availability of many of our cost components.  For a description of certain risks related to our raw materials, supplies and labor, see Item 1A, "Risk Factors" in this Annual Report on Form 10-K.
Alumina Supply Agreements
The majority of the alumina required for our operations is supplied by Glencore under long-term alumina supply agreements. Grundartangi also tolls alumina provided by Glencore into primary aluminum pursuant to the tolling agreement described above. The remainder of our alumina requirements are supplied under long-term supply agreements with Noranda and BHP Billiton. A summary of our alumina supply agreements is provided below:

Electrical power represents our single highest cost of goods sold. We may enter into forward contracts or other hedging arrangements to mitigate our electrical power or natural gas price risk, but did not hold any such contracts as of December 31, 2014. The paragraphs below summarize the sources of power and the long-term power arrangements for each of our operations.
Grundartangi. Power is supplied to Grundartangi from hydroelectric and geothermal sources under long-term power purchase agreements with HS, Landsvirkjun and OR at prices indexed to the price of primary aluminum, which provides a "natural hedge" of our largest production cost.  The expiration dates of these power purchase agreements range from 2019 through 2036 (subject to extension). The agreements contain take-or-pay obligations with respect to a significant percentage of the total committed and available power under each agreement.
Hawesville. Effective August 2013, we entered into a power supply arrangement with Kenergy and Big Rivers Electric Company ("Big Rivers") which provides market-based power to the Hawesville smelter. Under this arrangement, the power companies purchase power on the open market and pass it through to Hawesville at Midcontinent Independent System Operator ("MISO") pricing plus transmission and other costs incurred by Kenergy. In connection with this power arrangement, CAKY has received approval from applicable regional transmission organizations and regulatory bodies regarding grid stability and energy import capability. Effective January 1, 2015, new agreements were approved by the Kentucky Public Service Commission pursuant to which EDF Trading North America, LLC ("EDF") replaced Big Rivers as our market participant with MISO under this arrangement. See Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations - Electrical Power Developments in the United States in 2014."
Sebree. Effective February 2014, we entered into a power supply arrangement with Kenergy and Big Rivers which provides market based power to the Sebree smelter. Similar to the arrangement at Hawesville, the power companies purchase power on the open market and pass it through to Sebree at MISO pricing plus transmission and other costs incurred by Kenergy. Effective January 1, 2015, new agreements were approved by the Kentucky Public Service Commission pursuant to which EDF replaced Big Rivers as our market participant with MISO under this arrangement. See Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations - Electrical Power Developments in the United States in 2014."
Mt. Holly. Power is supplied to Mt. Holly pursuant to a power agreement with South Carolina Public Service Authority ("Santee Cooper") with an effective term through December 2015. This agreement provides power for Mt. Holly’s full production capacity requirements at prices based on published rate schedules (which are subject to change), with adjustments for fuel prices and other items.  The agreement restricts Mt. Holly’s ability to reduce its power consumption (or the associated

8


payment obligations) below contracted levels and to terminate the agreement, unless, in each case, the LME falls below certain negotiated levels.
Under this agreement, Mt. Holly receives all or a portion of its supplemental power requirements from an off-system natural gas-fired power generation facility.  The energy charge for supplemental power from the off-system facility is based, among other factors, on the cost of natural gas rather than Santee Cooper's system average fuel costs, which are primarily coal-based.
On June 30, 2014, Mt. Holly gave notice to Santee Cooper under the Santee Cooper Agreement to reduce the contract demand to zero effective December 31, 2015. We are continuing discussions with Santee Cooper and other parties regarding power arrangements for Mt. Holly following December 31, 2015. See "Item 1A, "Risk Factors — If we are unable to enter into a new power contract for Mt. Holly, we may be unable to operate Mt. Holly at a profitable level or at all."
Ravenswood. Ravenswood currently purchases a limited amount of power from APCo as necessary to maintain its curtailed smelter.  Power is supplied under the APCo Agreement at prices set forth in published tariffs (which are subject to change), with certain adjustments.
Helguvik. We have entered into power purchase agreements with HS and OR for the provision of 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 agreements contain certain conditions to HS’s and OR’s obligations. HS (with respect to all phases) and OR (with respect to all phases other than the first phase) have alleged that certain of these conditions 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 and is currently being utilized at Grundartangi. In July 2014, HS commenced arbitration proceedings against Nordural Helguvik ehf seeking, among other things, an order declaring that the conditions to the power contract have not been fulfilled and that the power contract is therefore no longer valid. Nordural Helguvik ehf is in discussions with both HS and OR with respect to such conditions and other matters pertaining to these agreements.
In June 2014, Nordural Helguvik ehf entered into a supplemental power contract with OR. The supplemental power contract will expire in October 2036 (or upon the occurrence of certain earlier events) and will provide Grundartangi or Helguvik with supplemental power at LME-based rates, as may be requested from Grundartangi or Helguvik from time to time.
See Note 15, "Commitments and contingencies" to the consolidated financial statements included herein for additional information concerning our power arrangements. See "Item 1A, "Risk Factors — If we are unable to procure a reliable source of power, the Helguvik project may not be feasible."

81% of Grundartangi’s workforce is represented by five labor unions, governed by a labor agreement that establishes wages and work rules for covered employees. This agreement expired on December 31, 2014. Since such time, we have been operating under the terms of the expired agreement while we engage in negotiations with the unions regarding the terms of a new agreement. 80% of Vlissingen's workforce is represented by the Federation for the Metal and Electrical Industry ("FME"), governed by a labor agreement that expires on May 1, 2015. The FME negotiates working conditions with trade unions on behalf of its members.
54% of our U.S. based workforce is represented by the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union ("USWA"). CAKY’s Hawesville employees represented by the USWA are under a collective bargaining agreement that expires on March 31, 2015. CAKY is currently in negotiations with the USWA with respect to a new agreement. In July 2014, Century Sebree entered into a new collective bargaining agreement with the USWA for its employees at the Sebree smelter.  The agreement is effective through October 28, 2019. The labor agreement for CAWV’s Ravenswood plant employees represented by the USWA expired on August 31, 2010.
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 as well as 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 Southwire, a large purchaser of aluminum for electrical wire and cable products.  This location allows Hawesville to deliver a portion of its production in molten form, saving casting costs, and providing a competitive advantage over other potential suppliers. In addition, Hawesville is the largest producer of high purity aluminum in North America.
We believe that the proximity of Iceland to European markets provides a competitive advantage for Grundartangi. We believe that this location offers Century logistical benefits and freight savings compared to our competitors outside the European Economic Area ("EEA"). As a member of the EEA, Iceland has duty free access to these European markets. In addition, the proximity to our customer base in key manufacturing areas in the United States provides a competitive advantage in freight costs over our foreign competitors.
We produce several primary products at our facilities, such as billet, foundry, slab and sow. Billet, foundry and slab are value-added primary aluminum products for which we receive a product premium above the LME and regional premiums.
For additional information, see Item 1A, "Risk Factors - We may be unable to continue to compete successfully in the highly competitive markets in which we operate."
Financial Information about Segments and Geographic Areas
We operate in one reportable segment, primary aluminum.  Additional information about our segment reporting and certain geographic information is available in Note 20, "Business segments" to the consolidated financial statements included herein.  
Environmental Matters
We are subject to various environmental laws and regulations in the countries in which we operate.  We have spent, and expect to continue to spend, significant amounts for compliance with those laws and regulations.  In addition, some of our past manufacturing activities have resulted in environmental consequences that 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 or the outcome of certain existing litigation to which we are a party.  Such future requirements or events may result in unanticipated costs or liabilities that 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 Note 15, "Commitments and contingencies" to the consolidated financial statements included herein.

Intellectual Property
We own or have rights to use a number of intellectual property rights relating to various aspects of our operations. We do not consider our business to be materially dependent on any of these intellectual property rights.
Disclosure Pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act
Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 ("ITRA"), effective August 10, 2012, added a new subsection (r) to Section 13 of the Exchange Act, which requires issuers that file periodic reports with the SEC to disclose in their annual and quarterly reports whether, during the reporting period, they or any of their "affiliates" (as defined in Rule 12b-2 under the Exchange Act) have knowingly engaged in specified activities or transactions relating to Iran, including activities not prohibited by U.S. law and conducted outside the U.S. by non-U.S. affiliates in compliance with applicable laws. Issuers must also file a notice with the SEC if any disclosable activity under ITRA has been included in an annual or quarterly report.
Because the SEC defines the term "affiliate" broadly, our largest stockholder may be considered an affiliate of the Company despite the fact that the Company has no control over its largest stockholder’s actions or the actions of its affiliates. As such, pursuant to Section 13(r)(1)(D)(iii) of the Exchange Act, the Company hereby discloses the following information provided by our largest stockholder regarding transactions or dealings with entities controlled by the Government of Iran ("the GOI"):
During 2014, as previously reported, a non-U.S. affiliate of the largest stockholder of the Company ("the non-U.S. Stockholder Affiliate") entered into sales contracts for agricultural products for delivery to Iranian entities wholly or majority owned by the GOI. The non-U.S. Stockholder Affiliate performed its obligations under the contracts in compliance with applicable sanction laws and, where required, with the necessary prior approvals by the relevant governmental authorities.
The gross revenue of the non-U.S Stockholder Affiliate related to these contracts did not exceed the value of $162 million for the twelve months ended December 31, 2014. The non-U.S. Stockholder Affiliate does not allocate net profit on a country-by-country or activity-by-activity basis, but estimates that the net profit attributable to the contracts would not exceed a small fraction of the gross revenue from such contracts. It is not possible to determine accurately the precise net profit attributable to such contracts.
The contracts disclosed above do not violate applicable sanctions laws administered by the U.S. Department of the Treasury, Office of Foreign Assets Control, and are not the subject of any enforcement action under Iran sanction laws.
In compliance with applicable economic sanctions and in conformity with US secondary sanctions, the non-U.S. Stockholder Affiliate expects to continue to engage in similar activities in the future.
Century and its global subsidiaries had no transactions or activities requiring disclosure under ITRA, nor were we involved in the transactions described in this section. As of the date of this report, the Company is not aware of any other activity, transaction or dealing by it or any of its affiliates during the twelve months ended December 31, 2014 that requires disclosure in this report under Section 13(r) of the Exchange Act.

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.
Declines in aluminum prices could have a material adverse effect on 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 and regional supply and demand, political and economic conditions and other related factors. The price of primary aluminum may also be impacted by LME inventory levels. Aluminum warehouse inventory levels remain at high levels. Continued high inventory levels, or the release of such inventory into the market, may cause primary aluminum prices and regional delivery and product premiums to decline.  Historically, aluminum prices have been volatile, and we expect such volatility to continue. The cash aluminum price, as quoted on the LME (the largest component of the overall price), averaged approximately $1,867 per tonne in 2014, which is below the average price of approximately $2,061 per tonne for the previous five years. The LME cash aluminum price on February 27, 2015 was $1,794 per tonne. Although Midwest and European Duty Paid premiums reached levels in 2014 higher than historical averages, these premiums may decrease, which would have a negative impact on our results of operations. Declines in aluminum prices (and regional delivery, product and other premiums) may materially and adversely affect our liquidity, the amount of cash flow we have available for our capital expenditures and other operating expenses, our ability to access the credit and capital markets and our results of operations.  If the price we realize for our products falls below our cost of production, we may choose or be forced to curtail all or a portion of our operations or otherwise restructure our operations.  There can be no assurance that we will be able to take actions necessary to curtail or otherwise restructure our operations, if these steps are required.  
Increases in energy costs adversely affect our business.
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. Each of our Hawesville and Sebree plants receives electricity under market-based electricity contracts. Market-based electricity contracts expose us to market price volatility and fluctuations and there can be no assurance that such market-based power supply arrangements will result in lower electricity costs. Electrical power prices have fluctuated significantly in recent years (for instance, as a result of extreme weather conditions), without any direct relationship to the price of aluminum. Increased electricity and energy prices could have a material adverse effect on our business, financial position, results of operations and liquidity.
A significant portion of the electrical power currently supplied to Mt. Holly is produced by natural gas. An increase in the price of natural gas would therefore increase the price that Mt. Holly pays for electricity. The Mt. Holly power contract also has take-or-pay type provisions, so our financial position, results of operations and cash flows from our Mt. Holly operations may be adversely affected by the price for electrical power even if we curtail unprofitable production capacity at this facility.
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.  Disruptions 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.  Our market-based power supply arrangements further increase the risk that disruptions in the supply of electrical power to our domestic operations could occur. Under these arrangements, we have greater exposure to transmission line outages, problems with grid stability and limitations on energy import capability. An alternative supply of power in the event of a disruption may not be feasible.  If a disruption in the supply of electrical power at one of our facilities were to occur, we may lose production for a prolonged period of time, experience pot instability that could decrease levels of productivity and incur significant losses. Such a condition may also force a curtailment of all or part of the production at any of these facilities and could have a material adverse effect on our business, financial position, results of operations and liquidity.
 

12


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 under certain circumstances.  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.
If we are unable to enter into a new power contract for Mt. Holly, we may be unable to operate Mt. Holly at a profitable level or at all.
In June 2014, Mt. Holly notified Santee Cooper of its election to reduce its contract demand to zero effective December 31, 2015.  We are currently in discussions with Santee Cooper regarding power arrangements for Mt. Holly following December 31, 2015, but no assurance can be given that we will come to an agreement on terms that are favorable to us, or at all. If a favorable power arrangement for Mt. Holly is not reached and approved prior to December 31, 2015, we may be unable to operate the Mt. Holly facility at a profitable level or at all. Closure of the Mt. Holly facility would impose various costs on us that could have a material adverse effect on our business, financial condition, results of operations and liquidity. In addition, uncertainty regarding the future operation of Mt. Holly may damage our relationships with our customers, suppliers, employees and other stakeholders, whether or not Mt. Holly is ultimately closed. We may need to take actions to terminate certain customer and supply contracts or curtail individual potlines well in advance of any plant closure. Customers and suppliers may also become unwilling to renew existing contracts or enter into new contracts with us. It may also become more difficult to attract and retain employees. Such actions and events could have a material adverse effect on our business, financial condition, results of operations and liquidity.
Curtailment of unprofitable aluminum production at our facilities could have a material adverse effect on our business, financial position, results of operations and liquidity.
 Curtailing unprofitable production to reduce our operating costs requires us to incur substantial expenses, 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.
 If we are unable to realize the intended cost saving effects of any production curtailment, including at our currently curtailed Ravenswood facility, we may have to seek bankruptcy protection for some or all of our subsidiaries; we could also be forced to divest some or all of these subsidiaries.  If we were to seek bankruptcy protection for any of these subsidiaries, we would face additional risks.  Such action could cause concern among our customers and suppliers, 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 an impact on the trading price of our securities and affect our ability to raise capital in the future.
 Any curtailments of our operations, or actions taken to seek bankruptcy protection or divest some or all of our subsidiaries, could have a material adverse effect on our business, financial position, results of operations and liquidity.
Construction at our Helguvik smelter site has been significantly curtailed.  Substantial delay in the completion of, or failure to complete, this project may increase its cost, subject us to losses 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 ongoing negotiations 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, financial and political conditions in Iceland were to deteriorate, our financial position and results of operations could be adversely impacted."  Nordural Helguvik ehf 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 earnings.
 

13


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 ehf 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.  We may also become liable to some of our suppliers for damages relating to delays in the project.
Even if we were to 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, in addition to procuring a reliable source of power, we may need to arrange additional financing and secure a supply of necessary raw materials.  Furthermore, unforeseen technical difficulties could increase the cost of the project, delay the project or render the project infeasible.
We intend to finance our future capital expenditures from available cash, cash flow from operations and accessing capital markets.  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 ehf has entered into agreements with two providers of 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.  In July 2014, HS commenced arbitration proceedings against Nordural Helguvik ehf seeking, among other things, an order declaring, (i) that the conditions to the power contract have not been fulfilled and, (ii) that the power contract is therefore no longer valid. If we are unable to reach agreement with each of HS and OR, we may have to seek alternative sources of power or incur substantially increased power costs and may be unable to complete 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, or any further delays in completing the 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 energy sources by our contracted power providers and completion of the necessary transmission infrastructure to service the Helguvik project.  If there are construction delays or technical difficulties in developing these new 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 energy sources and associated transmission infrastructure.  In addition, if Nordural Helguvik ehf 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.
Any restart of the Ravenswood smelter would involve significant risks and uncertainties.
 In 2009, we curtailed all operations at our Ravenswood smelter.  We may restart the curtailed operations upon the realization of several objectives, including an expectation of high long-term aluminum prices, a competitively priced power

14


agreement, passage of supporting legislation and a new labor agreement. If we are unable to realize these and other objectives, a restart of the Ravenswood smelter may not be feasible. Any potential restart of operations at the Ravenswood smelter would involve significant risks and uncertainties, including, significant costs and liabilities incurred to pursue a restart that does not occur or that does not achieve the anticipated benefits. Additionally, 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 position, results of operations and liquidity.
We may be unable to realize the expected benefits of our capital projects.
From time to time, we undertake strategic capital projects in order to enhance, expand and/or upgrade our facilities and operational capabilities. For instance, within the past several years we have undertaken major expansions of our Grundartangi and Vlissingen facilities. Our ability to achieve the anticipated increased revenues or otherwise realize acceptable returns on these investments or other strategic capital projects that we may undertake is subject to a number of risks, many of which are beyond our control, including a variety of market, operational, permitting, and labor-related factors. In addition, the cost to implement any given strategic capital project ultimately may prove to be greater than originally anticipated. If we are not able to achieve the anticipated results from the implementation of any of our strategic capital projects, or if we incur unanticipated implementation costs or delays, our results of operations and financial position may be materially adversely affected.

Our failure to maintain satisfactory labor relations could adversely affect our business.
 
The bargaining unit employees at our Grundartangi, Hawesville, Sebree, Vlissingen and Ravenswood facilities are represented by labor unions, representing 59% of our total workforce as of December 31, 2014.  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.  The collective bargaining agreement at our Grundartangi facility expired on December 31, 2014. Since such time, we have been operating under the terms of the expired agreement while we engage in negotiations with the unions regarding the terms of a new agreement. In addition, the collective bargaining agreements for our Hawesville and Vlissingen locations expire in March and May of 2015, respectively. We may not be able to renegotiate these or our other labor contracts on satisfactory terms. As part of any negotiation, we may reach agreements with respect to future wages and benefits that may have a material adverse effect on our future business, financial condition, results of operations and liquidity. In addition, negotiations could divert management attention or result in strikes, lock-outs or other work stoppages. 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 facilities subject to these collective bargaining agreements, which could have a material adverse effect on our business, financial position, results of operations and liquidity.

Disruptions to, or changes in the terms of, our raw material and electrical power supply arrangements could increase our production costs.
 
Our business depends upon the adequate supply of alumina, electrical power, aluminum fluoride, calcined petroleum coke, pitch, carbon anodes and cathodes and other 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.  For some of these production inputs, such as power and anode supply, we rely on a limited number of suppliers. Many of our supply agreements are short term or expire in the next few years. We can provide no assurance that we will be able to renew such agreements at commercially favorable terms, if at all.
 
Any supply disruption may require us to purchase these products on less favorable terms than under our current agreements due to the limited number of suppliers of these products or other market conditions.  In some instances, we may be unable to secure alternative supply of these resources. In addition, we may not be able to obtain alumina or power 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 or electrical power at comparable prices.
 

15


Certain of our alumina and electrical power supply contracts contain "take-or-pay" obligations.
 
We have obligations under certain contracts to take-or-pay for specified quantities of alumina and electrical power 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 electrical 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 electrical power or raw materials and may have a material adverse effect on our business, financial position, results of operations and liquidity.

We could be adversely affected by the loss of a major customer or changes in the business or financial condition of our major customers.
 
For the year ended December 31, 2014, we derived approximately 77% of our consolidated sales from two major customers: Southwire and Glencore.  Beginning in 2015, we expect to sell all or substantially all of our production to Glencore. A significant downturn or deterioration in the business or financial condition of any major customer could have a material adverse effect on our results of operations. In addition, any significant reduction in purchases from any major customer, loss of this customer or failure to renew our current agreement with Glencore at all or on as favorable terms could have a material adverse effect on our business, financial position, results of operations and liquidity.
New LME warehousing rules could cause aluminum prices to decrease.

The LME has adopted new rules, effective as of February 1, 2015, which require LME warehouses, under certain conditions, to deliver out more aluminum than they take in. These or other new rules could cause an increase in the supply of aluminum to enter the physical market and may cause regional delivery premiums, product premiums and LME aluminum prices to fall. Declines in aluminum prices (and regional delivery, product and other premiums) may materially and adversely affect our liquidity, the amount of cash flow we have available for our capital expenditures and other operating expenses, our ability to access the credit and capital markets and our results of operations.
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 and exchange, tariffs and other trade barriers, and the burdens of complying with a wide variety of foreign laws and regulations.  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 position, results of operations and liquidity.
Our international operations are also exposed to risks related to the challenges in obtaining permits necessary to run them.  For example, the Grundartangi expansion project is subject to the receipt of an operating permit from Icelandic regulators. If we are unable to obtain this permit, we will not be permitted to produce more than 300,000 tpy of primary aluminum at Grundartangi and we will only realize a partial return on our significant investment in the Grundartangi expansion project.
In addition, we may be exposed to fluctuations in currency exchange rates. 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 expansion programs at Grundartangi and Vlissingen and the Helguvik project, our currency risk with respect to the Icelandic krona ("ISK"), the euro and other foreign currencies will significantly increase.

16


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 transfer of funds into 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 position, results of operations and liquidity.
Because we own less than a majority of some of our operating assets, we cannot exercise complete control over their operations.
 We have a joint venture agreement pursuant to which we hold a 40% stake in BHH, a carbon anode and cathode facility located in the Guangxi Zhuang Autonomous Region of south China. Because we beneficially own less than a majority of the ownership interests in BHH, we have limited control of the operations of this facility. While we seek to exert as much influence with respect to the management and operation of this facility as possible, we are dependent on our co-owner to operate such assets.  Our co-owner may have interests, objectives and incentives with respect to such assets that differ from our own.
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 project and the expansion programs at Grundartangi and Vlissingen.  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.  
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 position, 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, and continues to be, adversely affected by unfavorable market and financial conditions.  Our existing credit ratings, or any future negative actions the credit agencies may take, could 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 in order to refinance our existing debt or raise new debt or equity could have a material adverse effect on our business, financial position, results of operations and liquidity.
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, 2014, we had an aggregate of approximately $255 million of outstanding debt and we may incur additional debt in the future.

17


 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, including contractual commitments, pension funding, and certain contingent obligations, 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 borrowings on our U.S. and Iceland revolving credit facilities 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, refinance our existing debt 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 position, 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 U.S. revolving credit facility and the indenture governing the 7.5% Senior Secured Notes due 2021 (the "7.5% Notes") limit 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.  In addition, the loan and security agreement governing our U.S. revolving credit facility and the indenture governing the 7.5% 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.
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 U.S. revolving credit facility and the indenture governing our 7.5% 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 currently restrict 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.
 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 changes in the extent and manner our assets are being used, changes in certain factors critical to our industry, as well as 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.  For instance, if we do not eventually resume operations at Ravenswood or we do not complete the Helguvik project, we may be required to recognize

18


a loss related to all or a portion of the assets of these facilities. The net carrying value of Ravenswood was approximately $46 million at December 31, 2014. The aggregate capital expenditures through December 31, 2014 related to the Helguvik project were approximately $148 million.  In the future, we will continue to evaluate our assets for impairments, which could be significant.  Any such adjustments would be in the form of a non-cash charge which would reduce our earnings and increase our accumulated deficit. Any of the foregoing could have a material adverse effect on our business, financial position and results of operations.
Climate change legislation or environmental regulations may adversely impact our operations.
 Climate change and greenhouse gas emissions are the subject of significant public and scientific attention in the countries in which we operate. In turn, increasing government attention is being paid to global climate issues and to emissions of greenhouse gases, including emissions of carbon dioxide from coal combustion by power plants. 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, in June 2014, the U.S. Environmental Protection Agency (the "EPA") announced its Clean Power Plan, which would impose the first federal limits on carbon dioxide emissions from power plants in the U.S. Final rules from the EPA are not expected until later in 2015. The potential impact of these regulations on us will depend on the specific requirements imposed by any such laws or regulations and the time periods over which those laws or regulations would be phased in. In addition, 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 implemented Directive 2003/87/EC, and is complying with the Directive by participating in the European Union ("EU") Emission Trade Scheme from January 1, 2013.  Although we will receive approximately 90% of needed carbon dioxide allowances for the Grundartangi smelter free of charge, the economic impact of implementing this system is not fully known as cost of allowances could rise and we cannot be certain that Helguvik will be granted free allowances if the project is completed.
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 compliance with such regulatory changes, increased energy costs, costs associated with 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 position, results of operations and liquidity.
We and our suppliers are subject to a variety of environmental laws and regulations that may have a material adverse effect on our business, financial position, results of operations and liquidity.
 We are obligated to comply with various foreign, 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. We also 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.  In addition, many of our key suppliers are subject to environmental laws and regulations that may affect their costs of production resulting in an increase in the price of the products that we purchase from them. For instance, some of the power we purchase in the United States is generated at coal-based power plants, which are subject to significant environmental regulation. 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 or operate in the future. In addition, overall production costs may become

19


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 expected.
Glencore may exercise substantial influence over us, and they may have interests that differ from those of our other stockholders.
Glencore beneficially owns approximately 41.8% of our outstanding common stock and all of our outstanding Series A Convertible Preferred stock. Through its ownership of our common and preferred stock, Glencore has a 46.5% economic ownership of Century. In addition, two of our seven directors are Glencore employees. Glencore is also our largest customer. During the year ended December 31, 2014, we derived approximately 65.4% of our consolidated sales from Glencore and we expect to sell substantially all of our production to Glencore in 2015. Century and Glencore enter into various transactions such as the purchase and sale of primary aluminum, purchase and sale of alumina, tolling agreements and certain forward financial contracts. Because of the interests described above, Glencore may have substantial influence over our business, and on the outcome of any matters submitted to our stockholders for approval.
In addition, certain decisions concerning our operations or financial structure may present conflicts of interest between Glencore and our other stockholders. For example, Glencore may in the future engage in a wide variety of activities in our industry that may result in conflicts of interest with respect to matters affecting us. In addition, because of the interests described above, any future agreements or arrangements that we enter into with Glencore may not be comparable to those we could have negotiated with an unaffiliated third party.
 Acquisitions could disrupt our operations and harm our operating results.
 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; and
we may not achieve the anticipated benefits from our acquisitions.
For example, we consummated the Mt. Holly acquisition in December 2014. We are subject to numerous risks following the consummation of any acquisition, including, for example, that we may incur costs and expenses associated with any unidentified or potential liabilities, we may not achieve anticipated revenue and cost benefits from the acquisitions and unforeseen difficulties may arise in integrating the acquired operations into our existing operations.
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 position, 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, 2014, we had federal net operating loss carryforwards of approximately $1.3 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 federal 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 such an ownership change and thus limit our ability to utilize net operating losses, tax credits and other tax assets to offset future taxable income.
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 we are 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

20


compete successfully, our business, financial position, results of operations and cash flows could be materially and adversely affected.
Unpredictable events, including natural disasters, dangerous weather conditions 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 and extreme weather events in 2010, 2011, 2012 and 2014, 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 off-site electrical substation owned and operated by the national power grid operator.
Future unpredictable events, including natural disasters, dangerous weather conditions and political unrest, may adversely affect our ability to conduct business by causing disruptions in Icelandic, Chinese, Dutch, 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.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations
Overview
We are a global producer of 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, among other factors.  The key determinants of our results of operations and cash flow from operations are as follows:
the price of primary aluminum, which is based on the LME, regional delivery premiums and any value-added product premiums;
the cost of goods sold, the principal components of which are electrical power, alumina, carbon products and labor, which in aggregate exceed 75% of our cost of goods sold; and  
our production volume.
Pricing
Primary aluminum is a global traded commodity and its price is effectively determined on the LME, plus any regional delivery and value-added product premiums. Because primary aluminum is a global commodity, the price for aluminum can be volatile and subject to many factors beyond our control. This price volatility is influenced primarily by the global supply-demand balance and other factors such as speculative activities by market participants, production activities by competitors and political and economic conditions, as well as production costs in major production regions. Increases or decreases in primary aluminum prices result in increases and decreases in our revenues (assuming all other factors are unchanged). We may enter into forward contracts or other hedging arrangements to mitigate our price risk, but did not hold any such contracts as of December 31, 2014.
The historic volatility of the price of aluminum is reflected in the chart below:

26


The average LME price for primary aluminum for 2014 was $1,867 per tonne, compared to $1,846 per tonne in 2013.  The average regional delivery premiums increased in 2014 to $450 per tonne for the U.S. Midwest premium from $244 per tonne in 2013 and $218 per tonne in 2012.  European Duty Paid Premiums showed similar increases.
The LME price of primary aluminum rebounded in 2014 with demand growth driving market deficits, particularly in North America and Europe. The LME aluminum price peaked over $2,100 per tonne in August 2014 before declining to $1,832 as of December 31, 2014. Regional market delivery premiums increased in 2014 to a high of $526 per tonne for the U.S. Midwest premium and $510 per tonne for the European Duty Paid Premium, compared to highs of $267 per tonne and $298 per tonne, respectively for 2013. However, various global macroeconomic and geopolitical uncertainties have recently pushed the LME price, the U.S. Midwest premium and the European Duty Paid Premium lower.
Our operating results are significantly impacted by changes in the price of primary aluminum and the materials used in its production, including electrical power, alumina, aluminum fluoride and carbon products. Because we sell our products based principally on the LME price for primary aluminum, regional delivery premiums and value-added product premiums, we cannot pass on increased production costs to our customers. Although we attempt to mitigate the effects of price fluctuations from time to time through the use of various fixed-price commitments, financial instruments and also by negotiating LME-based pricing in some of our raw materials and electrical power contracts, 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.
Electrical Power Developments in 2014
Electrical power represents our single largest operating cost. As a result, the availability of reliable electrical power at competitive prices is critical to the profitability and viability of our operations.  Historically, our domestic operations relied on long-term fixed price power supply agreements or power supply agreements based on tariff and/or cost-based pricing. Over the past two years, we have migrated our operations in Kentucky to market-based electrical power supply agreements. Currently, Hawesville and Sebree have market-based power agreements whereby EDF and Kenergy purchase power on the open market and pass it through to our operations at MISO pricing plus transmission and other costs incurred by them.
Power is supplied to Mt. Holly pursuant to a power agreement with Santee Cooper with an effective term through December 2015. Mt. Holly's current power agreement allows Mt. Holly to receive all or a portion of its supplemental power requirements from an off-system natural gas-fired power generation facility (the "off-system facility"). The energy charge for supplemental power from the off-system facility is based on the cost of natural gas rather than Santee Cooper's system average fuel costs, which are primarily coal-based. On June 30, 2014, Mt. Holly gave notice to Santee Cooper under the Santee Cooper Agreement to reduce the contract demand to zero effective December 31, 2015. We are continuing discussions with Santee Cooper and other parties regarding power arrangements for Mt. Holly following December 31, 2015. Unlike the utility serving our Kentucky operations, Santee Cooper is not a participant in an organized power market and any arrangements for power supply other than from Santee Cooper’s generation portfolio must be bilateral with an identified seller and transmission right.
We continue to engage in discussions with APCo and other stakeholders in West Virginia. The possibility of a restart of the curtailed operations at Ravenswood becomes more likely if we are able to negotiate a competitively priced power agreement.
Production/Shipment Volumes
Shipment volume is another of our key performance indicators.  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 production of primary aluminum, however, requires capital-intensive facilities and consumes large amounts of electrical power. The continuous production cycle of primary aluminum and the high costs associated with restarting operations after a prolonged interruption or curtailment limit our ability to scale our production to changing economic conditions.
Shipments were up year-over-year from 472,977 tonnes for the year ended December 31, 2013 to 570,600 tonnes for the year ended December 31, 2014, for our United States operations, primarily due to the acquisitions of the Sebree smelter in June 2013 and Mt. Holly in December 2014. In Iceland, shipments increased from 291,621 tonnes for the year ended December 31, 2013 to 296,525 for the year ended December 31, 2014, primarily due to increased production capacity as a result of the ongoing expansion project. Any adverse changes in the conditions that affect shipment volumes could have a material adverse effect on our results of operations and cash flows.

Year Ended December 31, 2014 Compared to Year Ended December 31, 2013
Net sales:  Higher shipment volumes, due a full year of ownership of the Sebree smelter which we acquired on June 1, 2013, the acquisition of the Mt. Holly smelter on December 1, 2014 and a shift in product mix from toll to direct sales at Grundartangi, had a $342.5 million positive impact on net sales. Higher price realizations had a positive impact on net sales of $134.2 million. Direct shipments from our four operating smelters increased 242,687 tonnes in 2014 compared to 2013. Toll shipments decreased 140,160 tonnes relative to the same period last year.
Gross profit:  During 2014, higher price realizations, net of LME-based power and alumina cost, increased gross profit by $150.7 million, while increased volume, due to the acquisition of the Sebree and Mt. Holly smelters and the mix shift between toll and direct sales at Grundartangi, increased gross profit by $3.9 million. In addition, we experienced $31.4 million in net cost decreases at our smelters relative to 2013, comprised of: lower costs for power and natural gas costs at our U.S. smelters, $45.3 million; other cost increases primarily related to increasing our presence in the value-added business, $9.8 million; and increased depreciation, $4.1 million.
As part of the accounting for the purchase of the Sebree smelter, we recorded a $36.6 million estimated liability for the power contract we assumed based on the difference between the forecasted contract rates and market power rates through the contract termination date in January 2014. This liability was fully amortized over the period from June 1, 2013 through January 31, 2014, resulting in a credit to our depreciation and amortization expense. During 2013, the credit for the amortization of the power contract was $31.0 million. During 2014, the credit for the amortization of the power contract was $5.5 million. This resulted in a year to year decrease in gross profit of $25.5 million.
Due to the nature of our business, our inventory values are subject to fluctuations in market value and these fluctuations may have a significant impact on cost of goods sold and gross profit in any period. On average our inventory turns eight times within a year and reductions in value below cost basis at the end of a period are the new basis for inventory as it turns in subsequent periods.
As of December 31, 2014, the market value of our inventory was above its cost basis requiring no valuation adjustments. As of December 31, 2013, the market value of our inventory was below its cost basis, resulting in the recording of a lower of cost or market ("LCM") valuation adjustment and a charge to cost of goods sold of $1.2 million for 2013.  During 2014, inventory with a $1.2 million market valuation adjustment was consumed into cost of goods sold at the lower basis. The net impact of the 2013 market valuation adjustment on the 2014 and 2013 comparative results is an increase in gross profit of $2.4 million.
Other operating expense – net: Other operating expense - net is primarily related to items associated with Ravenswood. Period to period charges at the facility have been relatively stable, but some post-employment benefits and other support charges are starting to trend downwards. In 2014, we offered a lump sum payout to certain former employees with vested pension benefits in an effort to reduce our long-term pension liabilities. As a result, we recorded a settlement charge of $4.7 million to other operating expense-net.
Selling, general and administrative expenses: During 2014, we experienced decreased selling, general and administrative charges due to a reduction in external legal and outside professional service support and the absence of the relocation and severance expenses we incurred in 2013 to move our corporate headquarters to Chicago. In 2014, we incurred additional charges of $2.6 million related to the separation of former senior executives. We recorded a charge of $8.4 million in 2013 related to the separation of our former chief executive officer. Also, we incurred $8.6 million of general and administrative expenses in 2013 that relate to the integration of the Century Vlissingen anode facility into our business. The Century Vlissingen anode facility is now producing anodes and its costs are included in cost of goods sold in 2014.
Net gain (loss) on forward and derivative contracts: The net gain on forward and derivative contracts in 2013 was primarily the result of an increase in the fair value of a derivative asset embedded in the E.ON contingent liability. This change in fair value resulted in unrealized gains of $16.4 million in 2013. We have recorded unrealized gains of $1.4 million in 2014 related to the derivative asset embedded in the E.ON contingent liability.
Gain on bargain purchase: On June 1, 2013, we acquired the Sebree smelter. The allocation of the purchase price to the assets acquired and liabilities assumed is based on the estimated fair values at the date of acquisition. Based on the final purchase price allocation, we recorded a gain on bargain purchase of $5.3 million in 2013. See Note 2 Business acquisitions to the consolidated financial statements included herein for additional information.

30


Gain on fair value of contingent consideration: On December 1, 2014, we acquired Alcoa’s 50.3% stake in Mt. Holly for $67.5 million in cash less certain amounts owed by Alumax to the Mt. Holly operating partnership and for certain post-employment retiree medical obligations. The acquisition is also subject to adjustments for working capital and a true-up process intended to place the parties in approximately the same economic position as if the acquisition had closed on September 30, 2014. The purchase agreement includes a potential payment that will be based on the Midwest Transaction Price and production levels at Mt. Holly. The maximum amount of this post-closing cash payment by Century to Alcoa is $22.5 million and by Alcoa to Century is $12.5 million. The measurement period for this potential payment ends on December 31, 2015. At December 1, 2014, we estimated that we would make a payment to Alcoa of $13.8 million and recorded a liability of $13.8 million as contingent consideration on the opening balance sheet. Due to movements in aluminum market prices during December, the fair value of the contingent consideration was reduced by $7.9 million, resulting in a $7.9 million gain. See Note 2 Business acquisitions to the consolidated financial statements included herein for additional information.
Gain on remeasurement of equity investment: We accounted for the acquisition of Alcoa’s 50.3% stake in Mt. Holly as a step acquisition which required that we remeasure our existing 49.7% ownership interest (previously accounted for as an equity method investment) to fair value. The fair value of our interest in Mt. Holly was $56.7 million at closing, resulting in a non-cash pre-tax gain of $1.3 million in 2014. See Note 2 Business acquisitions to the consolidated financial statements included herein for additional information.
Loss on early extinguishment of debt: In 2013, as a result of the tender offer and redemption of our 8% senior secured notes due 2014 (the "8.0% Notes"), we recorded charges of $3.3 million for loss on early extinguishment of debt. We determined the tender and redemption of the 8.0% Notes should be treated as an extinguishment of the debt and accordingly, we recorded a loss on early extinguishment of debt in the second quarter of 2013. The loss on early extinguishment of debt consisted of the write-off of deferred financing costs and the debt discount associated with the 8.0% Notes, as well as the tender premium paid as part of the tender offer and redemption of the 8.0% Notes.
Income tax expense: We have a valuation allowance against all of our U.S. and certain foreign deferred tax assets. The significant driver of period to period differences in income tax expense is the change in earnings at our foreign entities that are not subject to a valuation allowance. See Note 14 Income taxes to the consolidated financial statements included herein for additional information.
Year Ended December 31, 2013 Compared to Year Ended December 31, 2012
Net sales: Net sales for the year ended December 31, 2013 increased $182.2 million to $1,454.3 million.  Higher shipment volumes had a $263.2 million positive impact on net sales. Direct shipments from our four operating smelters increased 108,376 tonnes in 2013 compared to 2012, due to the acquisition of the Sebree smelter on June 1, 2013. Toll shipments increased 9,693 tonnes relative to the same period last year. Lower price realizations for primary aluminum in the year ended December 31, 2013, negatively impacted our net sales by $81.0 million.  The monthly average LME cash price for 2013 was down approximately 9% from the monthly average LME cash price in 2012.  
Gross profit:  During 2013, lower price realizations, net of LME based alumina and power cost decreases, reduced gross profit by $52.0 million, with volume and mix decreasing gross profit by $5.3 million.  Offsetting the gross profit reduction of $57.3 million described above were $40.5 million in net cost decreases comprised of: reduced costs for power and natural gas at our U.S. smelters, $12.7 million; reduced costs for maintenance, supplies and materials, $34.9 million; offset by other cost increases, $3.0 million; and higher depreciation charges, $4.1 million.
As part of the accounting for the purchase of the Sebree facility, we recorded a $36.6 million liability for the power contract we assumed based on the difference between the forecasted contract rate and market power rates through the contract termination date in January 2014. This liability will be fully amortized over the period from June 1, 2013 through January 31, 2014 resulting in a credit to our cost of goods sold. During 2013, the credit was $31.0 million reflecting seven months amortization under Century's ownership.
Due to the nature of our business, our inventory values are subject to fluctuations in market value and these fluctuations can have a significant impact on cost of goods sold and gross profit in any period. On average our inventory turns eight times within a year and reductions in value below cost basis at the end of a period are the new basis for inventory as it turns in subsequent periods.

31


As of December 31, 2013, the market value of our inventory was below its cost basis, resulting in the recording of a LCM valuation adjustment and a charge to cost of goods sold of $1.2 million for 2013. During 2012, inventory with a $19.8 million lower basis due to a LCM valuation adjustment at December 31, 2011, was consumed into cost of goods sold at the lower basis. The net impact of the December 31, 2013 and December 31, 2011 market valuation adjustments on the 2013 and 2012 comparative results is a negative gross profit change of $21.0 million.
Other operating expense – net: Other operating expense is primarily related to costs associated with Ravenswood. In 2012, we accrued for a legal liability that was ultimately settled in 2013 for an amount lower than the accrual. This resulted in a year over year improvement of $6.0 million. A significant portion of the remaining improvement is due to lower expenses for employee benefits.
Selling, general and administrative expenses: During 2013, relocation and severance expenses related to moving our headquarters to Chicago increased selling, general and administrative expenses by $5.8 million; litigation matters, accruals for our performance-based compensation program and other general expenses increased expenses by approximately $7.6 million. In addition, we recorded a charge of $8.4 million in 2013 related to the separation of our former chief executive officer. We also incurred approximately $2.5 million in additional selling, general and administrative expenses associated with the newly acquired Sebree facility. In addition, we experienced a $7.8 million increase in general and administrative expenses in 2013 related to the integration of the Century Vlissingen carbon anode facility into our business. With the restart of operations, Vlissingen costs will be recorded in cost of goods sold beginning in 2014.
Net gain (loss) on forward and derivative contracts: The net gain on forward and derivative contracts in 2013 was primarily the result of an increase in the fair value of an embedded derivative asset in the E.ON contingent liability. This change in fair value resulted in unrealized gains of $16.8 million in 2013. The net loss on forward and derivative contracts in 2012 related primarily to marking-to-market, and recording settlements, of option contracts that were put in place to provide partial downside price protection for our domestic facilities. As of June 30, 2012, all of these option contracts were settled.
Gain on bargain purchase: On June 1, 2013, we acquired the Sebree smelter. Based on the purchase price allocation, we recorded a gain on bargain purchase of $5.3 million. The gain on bargain purchase reflects the LME market and the risk associated with the power agreement for the facility at June 1, 2013. See Note 2 Business acquisitions to the consolidated financial statements included herein for additional information.
Loss on early extinguishment of debt: As a result of the tender offer and redemption of the 8% Notes, we recorded charges of $3.3 million for loss on early extinguishment of debt. The loss on early extinguishment of debt consisted of the write-off of deferred financing costs and the debt discount associated with the 8.0% Notes, as well as the tender premium paid as part of the 8.0% Notes Tender Offer. See Note 6 Debt to the consolidated financial statements included herein for additional information.
Other income – net: During 2012, Grundartangi received a $7.9 million settlement payment for the costs to repair a transformer damaged in transit, a related business interruption claim, interest and other fees associated with the claim. A significant portion of the remainder of other incomenet relates to exchange rate gains and losses, the majority of which relate to items denominated in ISK.
Income tax expense: Our 2013 and 2012 income tax expense was primarily driven by our earnings in Iceland.

Liquidity and Capital Resources 
Liquidity
Our principal sources of liquidity are available cash, cash flow from operations and available borrowings under our revolving credit facilities. We have also raised capital in the past through the public equity and debt markets, and we regularly explore various other financing alternatives. Our principal uses of cash are the funding of operating costs (including post-retirement 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, working capital and other general corporate requirements.
Our consolidated cash and cash equivalents balance at December 31, 2014 was approximately $163 million compared to $84 million at December 31, 2013.
Availability Under Our Credit Facilities
We have in place a senior secured revolving credit facility, dated May 24, 2013, as amended, with a syndicate of lenders which provides for borrowings of up to $150 million in the aggregate (the "U.S. revolving credit facility"). We have also entered into, through our wholly-owned subsidiary Nordural Grundartangi ehf, a $50 million revolving credit facility, dated November 27, 2013 (the "Iceland revolving credit facility"). Century's U.S. revolving credit facility matures in May 2018 and our Iceland revolving credit facility matures in November 2016.
As of December 31, 2014, our credit facilities had no amounts outstanding and approximately $89 million of net availability. We borrow and make repayments under our credit facilities in the ordinary course based on a number of factors, including the timing of payments from our customers and payments to our suppliers. Borrowings and repayments under our credit facilities for the year ended December 31, 2014 on a gross basis were approximately $92.4 million and $98.4 million, respectively. During the same period, total outstanding indebtedness under our credit facilities at any given time did not exceed $16.7 million.
In connection with the Mt. Holly acquisition, and in part to cover new security obligations relating to the power arrangement with Santee Cooper for Mt. Holly, we amended the U.S. revolving credit facility to increase our letter of credit sub-facility to $130 million for the period commencing on December 1, 2014 and ending on March 1, 2015 and to $100 million thereafter. As of December 31, 2014, we had approximately $111 million of letters of credit outstanding under our U.S. revolving credit facility. With the acquisition of Mt. Holly, Santee Cooper required us to post a $60 million letter of credit to secure our power obligations under the existing power contract. This letter of credit reduces automatically on a monthly basis beginning on April 1, 2015 by between $4 and $6 million until the letter of credit expires in February 2016. We are in discussions with Santee Cooper regarding power arrangements at Mt. Holly following December 31, 2015 and we may be required to post additional security in the form of letters of credit at such time.
In addition, on January 1, 2015, EDF replaced Big Rivers as our market participant with MISO for our power supply arrangements in Kentucky. The transition to EDF reduced our outstanding letters of credit by approximately $40 million.
The availability of funds under our credit facilities is limited by a specified borrowing base consisting of certain accounts receivable and inventory. Our metal sales agreements for 2015 have shorter payment terms than we have had historically. The shorter payment term will reduce our accounts receivable, which comprise part of the borrowing base of our revolving credit facilities, and could result in a corresponding reduction in availability under the revolving credit facilities. Although, the shorter payment terms will reduce our borrowing base, it should improve our cash and cash equivalents balance by accelerating payments from our customer and reducing finished goods inventory on-hand. In addition, any future curtailments of production capacity would reduce accounts receivable and inventory with similar effect.
Senior Secured Notes
We have $250 million in 7.5% senior secured notes payable that will mature on June 1, 2021. In the third quarter of 2014, we retired our remaining 7.5% senior unsecured notes due August 2014 with a $2.6 million payment to the noteholders.

33


Acquisitions
On December 1, 2014, we acquired Alcoa’s 50.3% stake in Mt. Holly for $67.5 million in cash less certain amounts owed by Alumax to the Mt. Holly operating partnership and for certain post-employment retiree medical obligations. The acquisition is also subject to adjustments for working capital and a true-up process intended to place the parties in approximately the same economic position as they would have been in had the acquisition closed on September 30, 2014. In December 2014, we made an initial payment of $53.8 million with available cash on hand. In the second quarter of 2015, we expect to make an additional payment of approximately $40.8 million, primarily related to pension funding. In addition, the purchase agreement provides for a post-closing cash payment to be made following December 31, 2015 based on changes in the Midwest Transaction Price between July 2, 2014 and December 31, 2015 and production levels at Mt. Holly from October 1, 2014 through December 31, 2015. The maximum amount of this post-closing cash payment by Century to Alcoa is $22.5 million and by Alcoa to Century is $12.5 million. See Note 2 Business acquisitions to the consolidated financial statements included herein for additional information.
Contingent Commitments
We have a contingent obligation to E.ON which consists of the aggregate E.ON payments made to Big Rivers on CAKY’s behalf in excess of the agreed upon base amount under the long-term cost-based power contract with Kenergy.  As of December 31, 2014, the principal and accrued interest for the E.ON contingent obligation was $18.2 million, which was fully offset by a derivative asset. We may be required to make installment payments for the E.ON contingent obligation in the future. 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, 2014 and management’s estimate of the LME forward market beyond the quoted market period, we have assessed that we will not be required to make payments on the E.ON contingent obligation during the term of the agreement through 2028. There can be no assurance that circumstances will not change thus accelerating the timing of such payments. See Note 5 Derivative and hedging instruments and Note 6 Debt to the consolidated financial statements included herein for additional information.
Employee Benefit Plan Contributions
In April 2013, we entered into a settlement agreement with the PBGC regarding an alleged "cessation of operations" at our Ravenswood facility as a result of the curtailment of operations at the facility.  Pursuant to the terms of the agreement, we will make additional contributions (above any minimum required contributions) to our defined benefit pension plans over the term of the agreement. The remaining contributions under this agreement are approximately $10.7 million, of which approximately $3.7 million was scheduled to be made in 2014. Under certain circumstances, in periods of low primary aluminum prices relative to our operations, we may defer one or more of these payments, but we would be required to provide the PBGC with acceptable security for any deferred payments. In 2014 and 2015, we elected to defer contributions under the PBGC agreement and have provided the PBGC with the appropriate security.
In addition to the contributions required pursuant to the PBGC settlement, based on current actuarial and other assumptions, we expect to make minimum required contributions to the qualified defined benefit plans and unqualified supplemental executive retirement benefits ("SERB") plan of approximately $3.6 million and $1.7 million, respectively, for total pension contributions of $5.3 million during 2015. We may choose to make additional contributions to these plans from time to time at our discretion.
Other Items
During the second quarter of 2014, Nordural ehf participated in the 50/50 ISK Auctions (the "Auctions") sponsored by the Central Bank of Iceland ("CBI") and may participate in future auctions. The Auctions allow authorized investors to exchange foreign currency for ISK with 50% exchanged at the official rate set by the CBI and 50% exchanged at the auction rate. The ISK received in the Auction must be invested in Iceland for a minimum of five years.
During 2014, we paid Icelandic withholding taxes on intercompany dividends of approximately $5.5 million. We anticipate these payments will be refunded in November 2015. In November 2014, we received a refund for Icelandic withholding taxes paid in 2013 of $9.5 million. The withholding taxes and associated refunds are payable in Icelandic kronur ("ISK") and we are subject to foreign currency risk associated with fluctuations in the value of the U.S. dollar as compared the ISK.

In August 2011, our Board of Directors approved a $60 million common stock repurchase program. Through December 31, 2014, we had expended approximately $50 million under the program. In February 2015, our Board of Directors authorized a $20 million increase in the stock repurchase plan. In 2015 through February 27, 2015, we repurchased $5.8 million of our common stock. As of March 2, 2015, we had $24.3 million remaining under the repurchase program authorization. The repurchase program may be expanded, suspended or discontinued by our Board, in its sole discretion, at any time.
In June 2012, Nordural Grundartangi ehf entered into a new supplemental power contract with Landsvirkjun. The supplemental power contract, which will expire in October 2029 (or upon the occurrence of certain earlier events), will provide Nordural Grundartangi ehf with supplemental power, as Nordural Grundartangi ehf may request from time to time, at LME-based variable rates. Nordural Grundartangi ehf has agreed to make certain prepayments to Landsvirkjun for power expected to be used at a later date in connection with the contract, which will reduce the price paid for power at the time of consumption. As of December 31, 2014, these power prepayments totaled approximately $2.1 million.
We are also 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 Note 15 Commitments and contingencies to the consolidated financial statements included herein for additional information.
Capital Resources
We intend to finance our future recurring capital expenditures from available cash, cash flow from operations and available borrowings under our revolving credit facilities. For major investment projects, such as the Helguvik project, we would likely seek financing from various capital and loan markets, and may potentially pursue the formation of strategic alliances. We may be unable, however, to issue additional debt or equity securities, or enter into other financing arrangements on attractive terms, or at all, 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 debt or capital markets and our financial condition.
Capital expenditures for 2014 were $55.1 million, compared to $68.1 million for 2013. Capital expenditures for 2014 include approximately $12.8 million for the Grundartangi expansion project and approximately $13.2 million was related to Vlissingen. The remaining amounts are related to upgrading production equipment, improving facilities and complying with environmental requirements. We believe total capital spending in 2015 will be approximately $80 to $90 million, primarily related to our ongoing expansion project at Grundartangi, our restart of the second furnace at Vlissingen and other investment projects at our North American facilities.
In connection with the restart and expansion of production capacity at Vlissingen, we made approximately $13.2 million in aggregate capital expenditures in 2014, compared to $18.2 million in 2013. In late 2014, we began a project to restart the second baking furnace at Vlissingen, which will increase total annual carbon anode production capacity to 150,000 tonnes. The project is expected to be completed by the end of 2015 at an estimated cost of $15 million.
In fourth quarter of 2014, we also began a capital project to improve the efficiency of Hawesville's carbon anode rodding operations. The project is expected to be completed in the fourth quarter of 2015 at an estimated cost of $16 million. We incurred $0.7 million in capital expenditures towards this project for the year ended December 31, 2014.
We have made aggregate capital expenditures through December 31, 2014 related to the construction and development of the Helguvik project of approximately $148 million and we continue to make capital expenditures for this project. We also have substantial future contractual commitments for the Helguvik project. Capital expenditures for 2014 for the Helguvik project were approximately $0.3 million. If we were to cancel the Helguvik project, we estimate that our exposure to contract cancellation costs and other costs would be approximately $20 million, of which we currently have accrued liabilities of approximately $12.1 million. We are continuing to negotiate with the power suppliers to the project to, among other things, remove all the remaining conditions to their obligations to supply contracted power. The timing of the power availability together with other factors will determine the timing of resumption of major construction activity at Helguvik. We expect that capital expenditures for this project will be less than $0.5 million per year until the restart of major construction activities at Helguvik. 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 has been significantly curtailed.  Substantial delay in the completion of this project may increase its cost, subject us to losses and impose other risks to completion that are not foreseeable at this time" included herein.

Adjusted EBITDA
We use certain non-GAAP measures when reviewing our operating results, including adjusted EBITDA. We define adjusted EBITDA as operating income (loss) adjusted for certain non-cash items from the statement of cash flows and certain non-recurring items.
Our calculations of adjusted EBITDA may not be comparable to similarly titled measures reported by other companies due to differences in the components used in their calculations. We believe the presentation of adjusted EBITDA is a useful measure to help investors evaluate our capacity to fund our ongoing cash operating requirements, including capital expenditures and debt service obligations. Adjusted EBITDA should not be considered as a substitute for operating income (loss) as determined in accordance with GAAP.
The following table includes a reconciliation of adjusted EBITDA to operating income (loss), the most comparable GAAP financial measure.

Net cash flow from operating activities for 2014 was $196.4 million, compared to $19.7 million for 2013. The increase in cash provided by operating activities in 2014 compared to 2013 was primarily due to $204 million higher adjusted EBITDA in 2014 compared to 2013, $3 million lower interest payments in 2014 compared to 2013 and $3 million lower pension contributions in 2014 compared to 2013. These increases in cash provided by operating activities were primarily offset by lower cash provided by changes in working capital, $19 million lower in 2014 compared to 2013, $11 million higher income tax payments in 2014 compared to 2013 and a one-time separation payment to our former CEO of $10 million paid in 2014.
Our cash flows from operating activities decreased to $19.7 million in 2013 from $37.1 million in 2012. The decrease in net cash from operating activities in 2013 was primarily due to $27 million lower adjusted EBITDA in 2013 compared to 2012, $9 million higher pension contributions in 2013 related to the PBGC settlement. In addition, in 2013, we paid a litigation settlement of $1.6 million; we received an insurance settlement of $7.9 million in 2012. Offsetting these decreases in cash flows, we received $8.1 million in net tax refunds in 2013 versus $13.7 million in net tax payments in 2012.
Our net cash used in investing activities for 2014 was $109.1 million, compared to $117.2 million for 2013. The decrease in cash used was due to $8.0 million lower capital expenditures in 2014 compared to 2013, $5 million lower capital

expenditures for Vlissingen in 2014 compared to 2013 as the restart of Vlissingen was completed. These decreases were offset by a $5.7 million increase in acquisitions, with the $53.8 million purchase of the Mt. Holly smelter in 2014 compared to the acquisition of the Sebree smelter in 2013 for $48.1 million.
Our net cash used in investing activities in 2013 was $117.2 million compared to $32.5 million in 2012. The increase in cash used was due to the purchase of the Sebree smelter in 2013, for $48.1 million. In addition, increased capital expenditures in 2013 compared to 2012 accounted for an increase of $29.3 million, primarily for the Grundartangi expansion project and Vlissingen restart. Restricted cash deposits were $1.2 million higher in 2013 compared to 2012 and payments received from joint ventures were $6.6 million lower in 2013.
Our net cash used in financing activities for 2014 was $8.2 million, compared to $2.4 million for 2013. In 2014, cash used in financing activities was related to $6 million in net repayments of the amounts borrowed under our revolving credit facilities and the extinguishment of the remaining $2.6 million of our 7.5% Notes due in 2014. In addition, we received $0.4 million from the exercise of stock options.
Our net cash used in financing activities during 2013 was $2.4 million. The cash used was primarily related to the tender offer, consent solicitation and redemption of our 7.5% Notes due 2014 and issuance of our 7.5% Notes. The net cost of our long-term debt transactions in 2013 was $8.5 million, offset by net borrowings under our revolving credit facilities of $6.0 million.

Critical Accounting Estimates
Our significant accounting policies are described in Note 1 Summary of significant accounting policies to 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 postretirement benefits ("OPEB"), deferred tax assets, accounting for business combinations 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 Postretirement Benefit Liabilities
We sponsor several pension and other postretirement 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 cost inflation rate and the long-term rate of return on plan assets.
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 high-quality zero coupon bonds.  We use the Ryan Discount Rate Curve (the "Ryan Curve") which is considered acceptable under generally accepted accounting principles in the United States ("GAAP"). We believe the Ryan Curve provides a method of developing spot curve yield (our discount rate) that is consistent with observable market conditions.  
The Ryan Curve was specifically developed to meet the criteria set forth in ASC 715 "Compensation Retirement Benefits."  The published information at the end of each calendar month includes spot rate yields (high quality 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 Ryan Curve rate represents the assumed 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 (that we believe is consistent with our plans).   

37


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 Ryan Curve rate provide a good approximation of the timing and amounts of our defined benefit payments under our plans and no adjustment to the Ryan Curve rate has been made.

Century provides postretirement 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 benefit obligation.  Changes in the health care cost trend rates have a significant effect on the amounts reported for the health care benefit obligation.
Medical cost inflation is initially estimated to be 8%, declining to 5% over seven 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 rate would have had the following effects in 2014

 Long-term Rate of Return on Plan assets assumption
We are currently using a 7.25% 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.

38


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 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 statement of operations and net deferred tax assets are adjusted accordingly.  Changes in 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 $748 million against all of our U.S. and Netherlands deferred tax assets and a portion of our Icelandic deferred tax assets as of December 31, 2014, due to our assessment that it is more likely than not that these assets will not be realized based on our cumulative net losses.
Accounting for Business Combinations
We account for acquired businesses using the purchase method of accounting, which requires that the assets acquired and liabilities assumed be recorded at the date of the acquisition at their respective estimated fair values. The judgments used to estimate the fair value assigned to each class of assets acquired and liabilities assumed, as well as the estimated life of each, can materially impact the results of operations for the current period and for periods subsequent to the acquisition through depreciation and amortization. For significant acquisitions, the purchase price allocation is carried out with assistance from independent third-party valuation specialists.
Mt. Holly Acquisition
On December 1, 2014, we completed the acquisition of Alcoa’s 50.3% stake in Mt. Holly for a purchase price of $67.5 million in cash subject to working capital and other similar adjustments.
Contingent consideration
The acquisition agreement provides for a post-closing cash payment, either by Century to Alcoa, or by Alcoa to Century, to be made following December 31, 2015 based on (i) changes in the Midwest Transaction Price for aluminum between July 2, 2014 and December 31, 2015 and (ii) the aggregate cast house production of Mt. Holly from October 1, 2014 through December 31, 2015. The maximum amount of this post-closing cash payment by (i) Century to Alcoa is $22,500 and (ii) Alcoa to Century is $12,500. Determining the fair value of the post-closing cash payment requires management to estimate the expected cast house production through December 31, 2015, and estimate the expected average Midwest Transaction Price during the remaining period through December 31, 2015. Our cast house production estimates are based on our business plan for the period covered. We estimated the Midwest Transaction Price using the LME forward curve and historical and estimated Midwest Premiums. There are no publicly published forward curves or future quotes for the Midwest Premium. We used estimates of the Midwest Premium that are consistent with our business planning activities. Changes in the estimates and assumptions we used could result in a materially different valuation of these assumed liabilities and their amortization, which could have had a material effect on our results of operations.
Sebree
As part of the Sebree acquisition, we assumed an unfavorable electrical power supply agreement with a fair value of approximately $36.6 million and recorded the liability on Sebree’s opening balance sheet. Determining the fair value of the assumed liability required us to make estimates of future prices under the existing electrical power supply agreement as well as estimates of future MISO prices plus transmission and other costs. In 2013, we recognized income of approximately $31.0 million related to the amortization of this unfavorable electrical power supply agreement liability. Changes in the estimates and assumptions we used could result in a materially different valuation of these assumed liabilities and their amortization, which could have had a material effect on our results of operations.

39


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 assets (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 assets (asset group), the remaining useful life, expenditures to maintain the 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 sales volumes, future selling prices and costs, alternative uses for the asset, and estimated proceeds from the disposal of the asset.  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.  These agreements contain certain conditions to the power suppliers' obligations and the power suppliers have alleged that certain of these conditions have not been satisfied. In July 2014, HS, one of our power suppliers, commenced arbitration proceedings against Nordural Helguvik ehf seeking, among other things, an order declaring, (i) that the conditions to the power contract have not been fulfilled and, (ii) that the power contract is therefore no longer valid. We are currently in negotiations with both power suppliers with respect to such conditions and other matters pertaining to these agreements. If we are unable to reach agreement regarding the satisfaction of the remaining conditions to the power agreements, 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 these suppliers 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.
The aggregate capital expenditures through December 31, 2014 related to the Helguvik project were approximately $148 million.  In evaluating the construction in progress at Helguvik, if we believe there are indicators of impairment, we would consider the costs to complete the construction and the estimated undiscounted future cash flows over the estimated useful life of Helguvik and compare the estimated undiscounted future cash flows to the carrying value and expected costs to complete construction of the Helguvik project to determine if an impairment exists.  If we do not restart construction, we may have to recognize a loss on our investment at the time that a decision is 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 $46 million at December 31, 2014.  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 that time.  The estimated future undiscounted cash flows assume that the operations at the Ravenswood facility will resume once adequate LME prices for primary aluminum are reached and upon the successful negotiation and execution of certain critical enabling agreements for power and labor. If we believed that there are indicators of an impairment, we would compare the estimated undiscounted future cash flows to the carrying value of Ravenswood and the expected cost of restarting the facility to determine if an impairment exists.
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 Note 15 Commitments and contingencies to the consolidated financial statements included herein for additional information.

(1)
Long-term debt includes principal repayments on the 7.5% Notes due 2021 and the IRBs.  Payments are based on the assumption that all outstanding debt instruments will remain outstanding until their respective due dates.  Based on the LME forward market prices for primary aluminum at December 31, 2014 and management's estimate of the LME forward market for periods beyond the quoted periods, we have assessed that we will not have any payment obligations for the E.ON contingent obligation through the term of the agreement, which expires in 2028.
(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, 2014 rate for that debt continues until the respective due date.  We assume that no interest payments on the E.ON contingent obligation will be paid through the term of agreement, see above.
(3)
Purchase obligations include long-term alumina, power contracts and anode contracts, excluding market-based power and raw material requirements contracts.  For contracts with LME-based pricing provisions, including our long-term alumina contracts and Icelandic power contracts, we assumed a LME price using the LME forward curve as of December 31, 2014.
(4)
Includes the undiscounted estimated benefit payments for our OPEB obligations, which are unfunded.
(5)
Other liabilities include estimated SERB benefit payments, workers' compensation benefit payments and asset retirement obligations.  Asset retirement obligations are estimated disposal costs for the potliner currently in service.

Item 7A.  Quantitative and Qualitative Disclosures about Market Risk
 
Commodity Price Sensitivity

We are exposed to price risk for primary aluminum.  From time to time, we may manage our exposure to fluctuations in the price of primary aluminum through financial instruments designed to protect our downside price risk exposure.  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.
 
For information about our long-term primary aluminum metal sales and tolling agreement, see Item 1, "Business" or Note 16 Forward delivery contracts and financial instruments to the consolidated financial statements included herein.
Apart from the Glencore Grundartangi Metal Agreement, the Southwire Metal Agreement (which expired at the end of 2014) and the Glencore Sweep Agreement (a contract for all metal produced in the U.S. in 2013, less existing sales agreements and valued-added metal sales, which expired at the end of 2013), we had the following forward delivery contractual commitments:

Hawesville and Sebree have market-based electrical power agreements. Under the market-based power agreements, EDF and Kenergy purchase market-based electrical power on the open market and pass it through to Hawesville and Sebree at MISO pricing, plus transmission and other costs incurred by them. See Part I, Item 1, "Business - Supply Contracts - Electrical Power Supply Agreements" for additional information about these market-based power agreements.
Electrical Power Price Sensitivity
With the movement toward market-based power supply agreements, we have increased our electrical power price risk for our domestic operations due to fluctuations in the price of power available on the MISO market. Power represents our single largest operating cost, so changes in the price and/or availability of market power could significantly impact the profitability and viability of our Hawesville, Sebree and Mt. Holly operations. Transmission line outages, problems with grid stability or limitations on energy import capability could also increase power prices, disrupt production through pot instability or force a curtailment of all or part of the production at these facilities. In addition, indirect factors that lead to power cost increases, such as any increasing prices for natural gas or coal, fluctuations in or extremes in weather patterns or new or more stringent environmental regulations may severely impact our financial condition, results of operations and liquidity.
While we currently have not entered into any forward contracts to mitigate the price risk associated with our open market power purchases, we may manage our exposure by entering into certain forward contracts or option contracts in future periods.

Foreign Currency
 
We are exposed to foreign currency risk due to fluctuations in the value of the U.S. dollar as compared to the ISK, the euro, the Chinese yuan and other currencies.  Grundartangi’s labor costs, part of its maintenance costs and other local services are denominated in ISK and a portion of its anode costs are denominated in euros and Chinese yuan.  We have deposits denominated in ISK in Icelandic banks; in addition, our tax payments in Iceland for withholding taxes on intercompany dividends and estimated payments of Icelandic income taxes and any associated refunds are denominated in ISK. 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 may incur further capital expenditures for Vlissingen in future periods. In addition, Vlissingen's labor costs, maintenance costs and other local services are denominated in euros. We expect to incur capital expenditures for the construction of the Helguvik project, although we continue to evaluate the Helguvik project’s cost, scope and schedule.  Upon a restart of major construction for the Helguvik project, we have forecasted that a significant portion of the capital expenditures would be denominated in currencies other than the U.S. dollar, with significant portions in ISK, euros and Swiss francs.
We may manage our exposure by entering into foreign currency forward contracts or option contracts for forecasted transactions and projected cash flows for foreign currencies in future periods.  As of December 31, 2014, we had no foreign currency forward contracts outstanding.  
 
Natural Economic Hedges
Any analysis of our exposure to the commodity price of aluminum should consider the impact of natural hedges provided by certain contracts that contain pricing indexed to the LME price for primary aluminum. Certain of our alumina contracts, as well as certain of Grundartangi’s electrical power and tolling contracts, are indexed to the LME price for primary aluminum and provide a natural hedge for a portion of our production.

Risk Management
 
Our metals, power, natural gas and foreign currency risk management activities are subject to the control and direction of senior management within guidelines established by Century’s Board of Directors.  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, 2014 and 2013, 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, 2014. Our audits also included the financial statement schedule listed in the Index at Item 15. These financial statements and the financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on the financial statements and the financial statement schedule 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, 2014 and 2013, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2014, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

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, 2014, based on the criteria established in Internal Control -Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 2, 2015 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, 2014, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. As described in Item 9A, Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at the Mt. Holly aluminum smelter, which was acquired on December 1, 2014, and whose financial statements constitute 10.4% of total assets and 1.3% of revenues of the consolidated financial statement amounts as of and for the year ended December 31, 2014. Accordingly, our audit did not include the internal control over financial reporting at the Mt. Holly aluminum smelter. 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, 2014, based on the criteria established in Internal Control - Integrated Framework (2013) 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 the financial statement schedule as of and for the year ended December 31, 2014 of the Company and our report dated March 2, 2015 expressed an unqualified opinion on those financial statements and the financial statement schedule.

We are constructing a primary aluminum facility in Helguvik, Iceland ("Helguvik" or the "Helguvik project") which is owned and would be operated through Nordural Helguvik ehf, a subsidiary of Nordural.    

Mt. Holly was operated as a joint venture between us and Alumax of South Carolina Inc. ("Alumax of SC") until our wholly-owned subsidiary, Berkeley Aluminum, Inc. ("Berkeley"), acquired Alumax of SC in December 2014. See Note 2 Business acquisitions for additional information about the Acquisition. Prior to the acquisition, Berkeley held a 49.7% interest in the partnership which operated 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's property, plant and equipment were owned by Alumax of SC.  Alcoa managed and operated Mt. Holly pursuant to an Owners Agreement. Pursuant to the Owners Agreement, each owner furnished their own alumina, for conversion to aluminum, and was responsible for their pro rata share of the operating and conversion costs.

In 2013, Century Sebree, acquired Sebree from a subsidiary of Rio Tinto Alcan, Inc. ("RTA").

In 2012, our wholly owned subsidiary, Century Aluminum Vlissingen B.V. ("Century Vlissingen") purchased a carbon anode production facility located in Vlissingen, the Netherlands ("Vlissingen"). Vlissingen restarted operations in late 2013 and supplies carbon anodes to Grundartangi.
 
We also own a 40% stake in Baise Haohai Carbon Co., Ltd. ("BHH"), a joint venture that owns and operates a carbon anode and cathode facility located in the Guangxi Zhuang Autonomous Region of south China.  BHH supplies anodes to Grundartangi.
 
Prior to our initial public offering, we were an indirect, wholly-owned subsidiary of Glencore plc (together with its subsidiaries, "Glencore").  At December 31, 2014, based on their filings with the Securities and Exchange Commission, Glencore owned 41.8% of Century’s outstanding common stock and all of our outstanding Series A Convertible Preferred stock. Through its ownership of our common and preferred stock, Glencore has an overall 46.5% economic ownership of Century.  Century and Glencore enter into various transactions such as the purchase and sale of primary aluminum, purchase and sale of alumina, tolling agreements and certain forward financial contracts.
 
Principles of Consolidation — The consolidated financial statements include the accounts of Century Aluminum Company and our subsidiaries, after elimination of all intercompany transactions and accounts. Our interest in the BHH joint venture are accounted for under the equity method. For BHH, we report our investment in its results of operations on a one-quarter lag.  
Reclassification — Certain immaterial amounts reported in previous years have been reclassified to conform to the current period presentation.

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.

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 $1,000 and $734 at December 31, 2014 and 2013, respectively.

Inventories — Our inventories are stated at the lower of cost or market ("LCM"), using the first-in, first-out ("FIFO") method.
 
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 – net.  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:

Building and improvements    10 to 45 years
Machinery and equipment         5 to 35 years
 
Impairment of long-lived assets — We review our property, plant and equipment for potential impairment 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 assets (asset group). In that case, an impairment loss would be recognized for the amount in which the carrying amount exceeds the fair value of the assets (asset group), with the fair value determined using the anticipated cash flows discounted at a rate commensurate with the risk involved. We estimate the future cash flows using management’s assumptions about the expected future use of the assets (asset group), the remaining useful life, expenditures to maintain the service potential, market and other 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 sales volumes, future selling prices and cost, alternative uses for the asset, and estimated proceeds from the disposal of the asset.  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 did not recognize any impairment losses on our long-lived fixed assets during 2014, 2013 or 2012

Business Acquisitions — We account for business acquisitions by applying the acquisition method in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 805 "Business Combinations." We allocate the purchase price to the assets acquired and liabilities assumed based on their estimated fair values on the date of the acquisition. The difference between the fair value of the net assets acquired and the purchase price is recorded as either goodwill or a bargain purchase gain. We record the operating results of our acquired businesses in our consolidated statements of operations from the date of acquisition.

Other Assets — Other assets consist primarily of Century’s investments in joint ventures, deferred financing costs, assets held in a Rabbi trust to fund the non-qualified supplemental executive retirement benefits ("SERB") pension benefit obligation, prepaid power costs, internal use software 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.
 
Prior to the Acquisition, we accounted 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 was held outside of the partnership and the undivided interest in these assets of the facility was accounted for in accordance with the 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, prior to the Acquisition, the undivided interest in these assets and the related depreciation were accounted for on a proportionate gross basis.
 
Income Taxes — We account for income taxes using the asset and 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

54

CENTURY ALUMINUM COMPANY
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

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 all of our net federal and state deferred tax assets.  We have a valuation allowance against a portion of our Icelandic and all of our Hong Kong and the Netherlands net operating loss ("NOL") deferred tax assets due to our belief that it is more likely than not that these assets will not be realized.  During 2012, we removed our election to permanently reinvest foreign earnings. See Note 14 Income taxes for additional information.

Defined Benefit Pension and Other Postretirement Benefits — We sponsor defined benefit pension and other postretirement benefit ("OPEB") plans for certain of our domestic hourly and salaried employees. We recognize expenses, assets and liabilities based on actuarial assumptions. We contribute to our defined benefit pension plans based upon actuarial and economic assumptions designed to achieve adequate funding of the projected benefit obligations and to meet the minimum funding requirements.  In addition, we maintain the SERB plan for certain current and former executive officers.  We account for these plans in accordance with ASC 715 "Compensation Retirement Benefits." We use a measurement date of December 31st to determine the pension and OPEB liabilities.
 
Postemployment Benefits — We provide certain postemployment benefits to certain 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 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 manage our exposure to changing primary aluminum prices.  
 
Certain physical delivery and financial sales contracts for primary aluminum that 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 and derivative contracts.  
 
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.  Grundartangi and Vlissingen use the U.S. dollar as their functional currency, however a portion of the operating expenses of their respective facilities are denominated and payable in currencies other than the U.S. dollar.  Grundartangi’s labor costs, part of its maintenance costs and other local services are denominated in ISK and a portion of its anode costs are denominated in euros.  Labor costs, maintenance costs and other local services at Vlissingen 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 – net in the consolidated statements of operations. As a result, an increase or decrease in the value of those currencies relative to the U.S. dollar would affect Grundartangi’s and Vlissingen's operating margins.  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, certain life insurance policies, payables, borrowings under our revolving credit facilities 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 values (based on the last available trading data) of our 7.5% senior secured notes due 2021 (the "7.5% Notes due 2021") and our 7.5% senior unsecured notes due 2014 (the "7.5% Notes due 2014").

CENTURY ALUMINUM COMPANY
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Earnings per share — Basic earnings (loss) per share ("EPS") amounts are calculated by dividing earnings (loss) available to common stockholders 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.

Our Series A Convertible Preferred Stock has similar characteristics to a "participating security" as described by ASC 260 "Earnings per Share" and we calculate the amount of net income (loss) allocated to common stockholders and basic EPS using the Two-Class Method earnings allocation formula, allocating undistributed income to our preferred shareholder consistent with their participation rights, and diluted EPS using the If-Converted Method when applicable.

Our Series A Convertible Preferred Stock is a non-cumulative perpetual participating convertible preferred stock with no set dividend preferences.  The holders of our convertible preferred stock do not have a contractual obligation to share in our losses.  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.

Asset Retirement Obligations — We are subject to environmental regulations which create certain legal obligations related to the normal operations of our domestic primary aluminum smelter operations. Our asset retirement obligations ("AROs") consist primarily of costs associated with the disposal of spent pot liner used in the reduction cells of our domestic facilities. AROs are recorded on a discounted basis, at the time the obligation is incurred (when the pot liner is put in service) and accreted over time for the change in the present value of the liability. We capitalize the asset retirement costs by increasing the carrying amount of the related long-lived assets and depreciating these assets over their remaining useful lives.

Certain conditional asset retirement obligations ("CAROs") related to the disposal costs of fixed assets at our primary aluminum facilities have not been recorded because they have an indeterminate settlement date.  CAROs are a legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within our control. We would recognize a CARO in the period in which sufficient information exists to reasonably estimate the fair value of the liability. These CAROs relate to the remediation of our primary aluminum facilities for certain regulated assets and hazardous material, such as landfills and asbestos and various other materials.
Concentrations of Credit Risk — Financial instruments, which potentially expose us to concentrations of credit risk, consist principally of trade receivables.  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.
 
Share-Based Compensation — We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. We recognize the cost over the period during which an employee is required to provide service in exchange for the award—the requisite service period (usually the vesting period). No compensation cost is recognized for equity instruments for which employees do not render the requisite service. 

The grant-date fair value of service-based share awards is equal to the closing stock price on the date of the grant. Stock option grant-date fair value is estimated using the Black-Scholes option-pricing model adjusted for the unique characteristics of those instruments. We have not issued any stock options since 2009. If an equity award is modified after the grant date, incremental compensation cost will be recognized in an amount equal to the excess of the fair value of the modified award over the fair value of the original award immediately before the modification.

We issue 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.

We award performance units to certain officers and employees. The performance units may be settled in cash or common stock at the discretion of the Board. These awards have historically been settled in cash, and we expect that to continue.
  
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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

In May 2014, the FASB and International Accounting Standards Board ("IASB") issued their final standard on revenue from contracts with customers. The standard, issued as ASU 2014-09 "Revenue From Contracts with Customers" by the FASB, outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance.
Compared with current GAAP, the ASU requires significantly expanded disclosures about revenue recognition. The ASU is effective for Century for our fiscal year 2017 and thereafter. Early adoption is not permitted. We are currently evaluating the impact of adoption on our consolidated financial position, results of operations and cash flows.
2. Business acquisitions
Acquisition of Mt. Holly aluminum smelter
On October 23, 2014, Berkeley entered into a stock purchase agreement (the "Stock Purchase Agreement") with Alumax Inc. ("Alumax"), a wholly owned subsidiary of Alcoa, to acquire Alcoa’s 50.3% stake in Mt. Holly. Upon closing of the transaction on December 1, 2014, Century owns 100% of Mt. Holly. Mt. Holly, located in Goose Creek, South Carolina, employs approximately 600 people and has an annual production capacity of 231,000 tonnes of primary aluminum.
Pursuant to the terms of the Stock Purchase Agreement, Berkeley agreed to acquire all of the issued and outstanding shares of capital stock of Alumax of SC for $67,500 in cash less certain amounts owed by Alumax to Mt. Holly and subject to working capital and other similar adjustments, of which we have paid approximately $53,831 as of December 31, 2014. The acquisition was funded with available cash on hand. We incurred $1,087 of acquisition-related costs during 2014. All acquisition-related costs were expensed to selling, general and administrative expenses during 2014.
Pension funding obligations
Alcoa spun-off the pension plan assets for the Mt. Holly employees and former employees into a qualified defined benefit pension plan established by Century. The new Mt. Holly pension plan benefit obligations were measured based on termination basis under IRS Code Section 414(l). The Mt. Holly pension plan was fully funded using the Pension Benefit Guaranty Corporation ("PBGC") assumptions, which are more conservative than the assumptions we use to measure our defined benefit obligations, and resulted in the recognition of a pension asset at closing.
Contingent Consideration - Earn-out provision
The Stock Purchase Agreement provides for a post-closing cash payment to be made following December 31, 2015 based on (i) changes in the Midwest Transaction Price for aluminum between July 2, 2014 and December 31, 2015 and (ii) the aggregate cast house production of Mt. Holly from October 1, 2014 through December 31, 2015. The maximum amount of this post-closing cash payment by (i) CASC to Alumax is $22,500 and (ii) Alumax to CASC is $12,500. We measured the fair value of the contingent consideration and recognized a $13,780 liability at December 1, 2014. Each period, until the end of the measurement period on December 31, 2015, we will remeasure the fair value of the contingent consideration. Any changes in the fair value will be recognized in earnings. In December 2014, we recognized $7,943 in gain on fair value of contingent consideration, primarily related to decreases in the forward curve of the LME price of primary aluminum.
Step Acquisition
In accordance with ASC 805, we accounted for this transaction as a step acquisition which required that we remeasure our existing 49.7% ownership interest (previously accounted for as an equity method investment) to fair value. The fair value of our interest in Mt. Holly was $56,723 at closing, resulting in a non-cash pre-tax gain of $1,318 included in gain on remeasurement of equity investment on our consolidated statements of operations for 2014. Our previously recorded equity method investment in Mt. Holly and the proportionally consolidated property, plant and equipment was derecognized from our consolidated balance sheets. Since the date of the step acquisition, the financial results of Mt. Holly were included within our consolidated financial statements.

The allocation of the purchase price to the assets acquired and liabilities assumed is based on the estimated fair values at the date of acquisition. The purchase price allocation is preliminary and subject to change based on the finalization of the valuation of assets and liabilities and the fair value of the previously held equity investment. The amounts presented below represent our estimates based on a preliminary valuation of certain assets and liabilities in connection with the acquisition of the Mt. Holly smelter. The results of the valuation are currently under review by management and are expected to be finalized in the second quarter of 2015.

Transactions Recognized Separately from the Mt. Holly acquisition
As part of the acquisition, we recognized two transactions as separate and apart from the business combination with Mt. Holly. The Mt. Holly smelter tolled alumina for its partners and so had no alumina supply of its own. Upon the purchase, we negotiated with Alcoa to purchase alumina under two separate alumina supply agreements. We believe the price paid under these agreements was equivalent to a market rate that would be paid by a market participant. Contract prices were based on published alumina price indexes. In addition, we had a pre-existing relationship with Alcoa prior to the acquisition of Mt. Holly. Mt. Holly had receivables due from Alcoa's subsidiary, Alumax, that were part of the normal operations of the business. We assessed that these receivables were effectively settled as a result of the acquisition and were accounted for separately from the business combination. The receivables will be settled at an amount calculated consistent with the practices of Mt. Holly. The amounts due from Alumax are identified in the table above and recorded in the consolidated financial statements in accrued and other current liabilities as an offset against amounts due to Alcoa.

Acquisition of Sebree aluminum smelter
On June 1, 2013, Century Sebree acquired the Sebree aluminum smelter from a subsidiary of RTA. Sebree, located in Robards, Kentucky, had an annual hot metal production capacity of 205,000 tonnes of primary aluminum and employed approximately 500 people as of the acquisition date. The purchase price for the acquisition was $61,000 (subject to customary working capital adjustments). As part of the transaction, RTA retained all historical environmental liabilities of the Sebree smelter and funded the pension plan assumed by Century in accordance with the purchase agreement.
Working Capital Adjustment    
In July 2014, we reached the final determination of the working capital adjustments for the Sebree acquisition, resulting in a final purchase price of $49,035. As the final determination was subsequent to the expiration of measurement period defined under ASC 805, we recognized a gain of approximately $965 in the second quarter of 2014 (these adjustments were not included as part of the gain on bargain purchase recorded in 2013). The gain was recorded in other income – net, from the release of accrued amounts related to the acquisition.
Purchase Price Allocation
Allocating the purchase price to the acquired assets and liabilities involves management judgment. We allocated the purchase price in accordance with ASC 805 using the estimated fair values at the date of acquisition. Based on the final purchase price allocation, we recorded a gain on bargain purchase of $5,253 in 2013.
