CENTURY ALUMINUM COMPANY

Condensed Notes to the Consolidated Financial Statements

Three and six months ended June 30, 2014 and 2013

(amounts in thousands, except share and per share amounts)

(Unaudited)

1. General

The accompanying unaudited interim consolidated financial statements of Century Aluminum Company should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2013. In management’s opinion, the unaudited interim consolidated financial statements reflect all adjustments, which are of a normal and recurring nature, that are necessary for a fair presentation of financial results for the interim periods presented. Operating results for the first six months of 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. Throughout this Form 10-Q, and unless expressly stated otherwise or as the context otherwise requires, "Century Aluminum," "Century," the "Company", "we," "us," "our" and "ours" refer to Century Aluminum Company and its consolidated subsidiaries.

In the second quarter of 2013, we acquired the Sebree smelter and reported provisional amounts for the assets acquired and the liabilities assumed in our Form 10-Q for the period ended June 30, 2013. See Note 2 Acquisition of Sebree aluminum smelter for additional information. In accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 805 "Business Combinations," we retrospectively adjusted our 2013 interim consolidated financial statements for certain measurement period adjustments for the items acquired in the acquisition and the financial results for 2013 presented in this Form 10-Q reflect these adjustments.

2. Acquisition of Sebree aluminum smelter

On June 1, 2013, our wholly owned subsidiary, Century Aluminum Sebree LLC ("Century Sebree"), acquired the Sebree aluminum smelter ("Sebree") from a subsidiary of Rio Tinto Alcan, Inc. ("RTA"). Sebree, located in Robards, Kentucky, has an annualized hot metal production capacity of 205,000 tonnes of primary aluminum and employs approximately 500 people. The purchase price for the acquisition was $61,000 (subject to customary working capital adjustments), of which we have paid approximately $48,000 as of June 30, 2014. 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, subsequent to the end of the quarter, we reached the final determination of the working capital adjustments, resulting in a final purchase price for the acquisition of $49,035. See Note 18 Subsequent events for additional information.

Purchase Price Allocation

Allocating the purchase price to the acquired assets and liabilities involves management judgment. We allocated the purchase price to the assets acquired, liabilities assumed, and the gain on bargain purchase in accordance with ASC 805.

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. We have finalized the purchase price allocation for the assets acquired and liabilities assumed, the purchase price and gain on bargain purchase.

Based on the purchase price allocation, we recorded a gain on bargain purchase of $5,253 in 2013. The following table summarizes the fair value of the assets acquired and the liabilities assumed as of the acquisition date:

The following unaudited pro forma financial information for the three and six months ended June 30, 2013 reflects our results of continuing operations as if the acquisition of Sebree had been completed on January 1, 2013. This unaudited pro forma financial information is provided for informational purposes only and is not necessarily indicative of what the actual results of operations would have been had the transactions taken place on January 1, 2013, nor is it indicative of the future consolidated results of operations or financial position of the combined companies.

Our net income for the six months ended June 30, 2014 includes a non-recurring credit for the amortization of the deferred power contract liability of $5,534 related to the amortization of an unfavorable power contract assumed as part of the Sebree acquisition resulting in a credit to our depreciation and amortization expense within cost of goods sold on the consolidated statement of operations for the first quarter of 2014. The power contract terminated on January 31, 2014.

3. Fair value measurements

The following section describes the valuation methodology used to measure our financial assets and liabilities that were accounted for at fair value and are categorized based on the fair value hierarchy described in ASC 820 "Fair Value Measurements and Disclosures."

Cash equivalents	1	Quoted market prices
Trust assets (1)	1	Quoted market prices
Surety bonds	1	Quoted market prices
E.ON ("E.ON") contingent obligation	3	Quoted London Metal Exchange ("LME") forward market, management’s estimates of the LME forward market prices for periods beyond the quoted periods and management’s estimate of future level of operations at Century Aluminum of Kentucky, our wholly owned subsidiary ("CAKY")
Primary aluminum sales contract	3	Management’s estimates of future U.S. Midwest premium and risk-adjusted discount rates
Midwest premium contracts	3	Management’s estimates of future U.S. Midwest premium

(1) Trust assets are currently invested in money market funds. These trust assets are held to fund the non-qualified supplemental executive pension benefit obligations for certain of our officers. The trust has sole authority to invest the funds in secure interest producing investments consisting of short-term securities issued or guaranteed by the United States government or cash and cash equivalents.

Fair value measurements

Our fair value measurements include the consideration of market risks that other market participants might consider in pricing the particular asset or liability, specifically non-performance risk and counterparty credit risk. Consideration of the non-performance risk and counterparty credit risk are used to establish the appropriate risk-adjusted discount rates used in our fair value measurements.

The following table sets forth our financial assets and liabilities that were accounted for at fair value on a recurring basis by the level of input within the ASC 820 fair value hierarchy.  As required by generally accepted accounting principles in the United States ("GAAP") for fair value measurements and disclosures, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.  Our assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and the placement within the fair value hierarchy levels. There were no transfers between Level 1 and 2 during the periods presented. There were no transfers into or out of Level 3 during the periods presented. It is our policy to recognize transfers into and transfers out of Level 3 as of the actual date of the event or change in circumstances that caused the transfer.

(1) See Note 9 Debt for additional information about the E.ON contingent obligation.

Midwest premium contracts

We entered into a fixed-price forward contract that settled monthly from January 2014 to March 2014 based on the

Midwest premium price published in the Platts Metals Week for the applicable period. Losses associated with the settlements of the U.S. Midwest premium contracts were recorded in net gain (loss) on forward and derivative contracts on the consolidated

statement of operations.

Primary aluminum sales contract

We had a contract to sell to Glencore plc (together with its subsidiaries, "Glencore") primary aluminum produced at Mt. Holly, Hawesville and Sebree through December 31, 2013 (the "Glencore Metal Agreement"). The Glencore Metal Agreement was a physical delivery contract for primary aluminum with variable, LME-based pricing.  Under the Glencore Metal Agreement, pricing was based on market prices, adjusted by a negotiated U.S. Midwest premium with a cap and a floor as applied to the current U.S. Midwest premium.  We accounted for the Glencore Metal Agreement as a derivative instrument under ASC 815 "Derivatives and Hedging."  Gains and losses on the derivative were based on the difference between the contracted U.S. Midwest premium and actual and forecasted U.S. Midwest premiums.  Settlements were recorded in related party sales.  Unrealized gains (losses) based on forecasted U.S. Midwest premiums were recorded in net gain (loss) on forward and derivative contracts on the consolidated statements of operations.

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

5.Earnings (loss) per share

Basic earnings (loss) per share ("EPS") amounts are calculated by dividing earnings 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 and we calculate the amount of earnings (loss) available to common shareholders 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.

The following table shows the basic and diluted earnings (loss) per share for the three and six months ended June 30, 2014 and 2013:

CENTURY ALUMINUM COMPANY

Condensed Notes to the Consolidated Financial Statements (continued)

(amounts in thousands, except share and per share amounts)

(Unaudited)

Under our Restated Certificate of Incorporation, our Board of Directors is authorized to issue up to 195,000,000 shares of our common stock.

The rights, preferences and privileges of holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock which are currently outstanding, including our Series A Convertible Preferred Stock, or which we may designate and issue in the future.

Stock Repurchase Program

In August 2011, our Board of Directors approved a stock repurchase program. Under the program, we may repurchase up to $60,000 of our outstanding shares of common stock from time to time on the open market at prevailing market prices, in block trades or otherwise. The timing and amount of any shares repurchased is determined by our management based on its evaluation of market conditions, the trading price of the stock and other factors. The repurchase program may be suspended or discontinued at any time.

Shares of common stock repurchased are recorded at cost as treasury stock and result in a reduction of shareholders’ equity in the consolidated balance sheets. From time to time, treasury shares may be reissued as contributions to our employee benefit plans and for the conversion of convertible preferred stock. When shares are reissued, we use an average cost method for determining cost. The difference between the cost of the shares and the reissuance price is added to or deducted from additional paid-in capital.

From August 11, 2011 through June 30, 2014, we repurchased 4,786,521 shares of common stock for an aggregate purchase price of $49,924. We have made no repurchases since March 2012 and had approximately $10,076 remaining under the repurchase program authorization as of June 30, 2014.

Series A Convertible Preferred Stock

Glencore holds all of the issued and outstanding Series A Convertible Preferred Stock. The issuance of common stock under our stock incentive programs, debt exchange transactions and any stock offering that excludes Glencore participation triggers anti-dilution provisions of the preferred stock agreement and results in the automatic conversion of Series A Convertible Preferred Stock shares into shares of common stock. The Common and Preferred Stock Activity table below contains additional information about preferred stock conversions during the six months ended June 30, 2014 and 2013.

Common and Preferred Stock Activity:	Preferred stock		Common stock

7. Income taxes

We recorded income tax expense for the six months ended June 30, 2014 of $560, which primarily consisted of foreign and state income taxes. Our domestic deferred tax assets, net of deferred tax liabilities, are subject to a valuation allowance; therefore, the domestic losses were not benefited. 

We recorded income tax expense for the six months ended June 30, 2013 of $3,330, which primarily consisted of foreign and state income taxes.

Our income tax benefit or expense is based on an annual effective tax rate forecast, including estimates and assumptions that could change during the year. The application of the requirements for accounting for income taxes in interim periods, after consideration of our valuation allowance, causes a significant variation in the typical relationship between income tax expense and pretax accounting income.

As of June 30, 2014, all of Century's U.S. and certain foreign deferred tax assets, net of deferred tax liabilities, continue to be subject to a valuation allowance. The realization of these assets is dependent on substantial future taxable income which, at June 30, 2014, is not more likely than not to be achieved.

Our Icelandic tax returns are subject to examination beginning with the 2008 tax year. Our 2010 through 2012 tax years are currently under review by the Directorate of Internal Revenue of Iceland.

8. Inventories

Inventories consist of the following:	June 30, 2014		December 31, 2013
Raw materials	$	54,168	$	69,776

Inventories are stated at the lower of cost or market, using the first-in, first-out method.

9. Debt

	June 30, 2014		December 31, 2013
Debt classified as current liabilities:
Hancock County industrial revenue bonds ("IRBs") due 2028, interest payable quarterly (variable interest rates (not to exceed 12%)) (1)	$	7,815	$	7,815
7.5% senior unsecured notes due August 15, 2014, interest payable semiannually (2)	2,603		2,603
Iceland revolving credit facility (2)(3)	—		6,000
Debt classified as non-current liabilities:
7.5% senior secured notes due June 1, 2021, net of debt discount of $3,295 and $3,472, respectively, interest payable semiannually	246,705		246,528
TOTAL	$	257,123	$	262,946

(1) The IRBs are classified as current liabilities because they are remarketed weekly and could be required to be repaid upon demand if there is a failed remarketing. The IRB interest rate at June 30, 2014 was 0.26%.

(2) These items are recorded in accrued and other current liabilities based on the repayment terms and expected maturity.

(3) Borrowings under the Iceland revolving credit facility bear variable interest based on LIBOR plus the applicable margin per annum. The interest rate at December 31, 2013 was 3.92%.

U.S. Revolving Credit Facility

General.  We and certain of our direct and indirect domestic subsidiaries (together with Century, the "Borrowers") and Wells Fargo Capital Finance, LLC, as lender and agent, and Credit Suisse AG, BNP Paribas, and Morgan Stanley Senior Funding Inc., as lenders, entered into the Amended and Restated Loan and Security Agreement (the "U.S. revolving credit facility"), dated May 24, 2013, as amended, modifying our credit facility dated July 1, 2010. The U.S. revolving credit facility has a term through May 24, 2018 and provides for borrowings of up to $150,000 in the aggregate, including up to $80,000 under a letter of credit sub-facility.  Any letters of credit issued and outstanding under the U.S. revolving credit facility reduce our borrowing availability on a dollar-for-dollar basis.  

Status of our U.S. revolving credit facility:

	June 30, 2014
Credit facility maximum amount	$	150,000
Borrowing availability, net of outstanding letters of credit	79,455
Outstanding borrowings	—
Letter of credit sub-facility amount	80,000
Outstanding letters of credit issued	70,545

Borrowing Base.  The availability of funds under the U.S. revolving credit facility is limited by a specified borrowing base consisting of accounts receivable and inventory of the Borrowers which meet the eligibility criteria.  

Guaranty.  The Borrowers' obligations under the U.S. revolving credit facility are guaranteed by certain of our domestic subsidiaries and secured by a continuing lien upon and a security interest in all of the Borrowers' accounts receivable, inventory and certain bank accounts.  Each Borrower is liable for any and all obligations under the U.S. revolving credit facility on a joint and several basis.

Interest Rates and Fees.  Any amounts outstanding under the U.S. revolving credit facility will bear interest, at our option, at LIBOR or a base rate, plus, in each case, an applicable interest margin.  The applicable interest margin is determined based on the average daily availability for the immediately preceding quarter.  In addition, we pay an unused line fee on undrawn amounts, less the amount of our letters of credit exposure.  For standby letters of credit, we are required to pay a fee on the face amount that varies depending on whether the letter of credit exposure is cash collateralized.

Iceland Revolving Credit Facility

General. Nordural Grundartangi ehf, as borrower, and Landsbankinn hf., as lender, entered into a three-year $50,000 Committed Revolving Credit Facility agreement (the "Iceland revolving credit facility"), dated November 27, 2013. Grundartangi may in the future use the Iceland revolving credit facility to repay existing indebtedness or to finance capital expenditures and for ongoing working capital needs and other general corporate purposes. Under the terms of the Iceland revolving credit facility, when Grundartangi borrows funds it will designate a repayment date, which may be any date prior to the maturity of the Iceland revolving credit facility. The Iceland revolving credit facility will mature on November 27, 2016.

Status of our Iceland revolving credit facility:

	June 30, 2014
Credit Facility maximum amount	$	50,000
Borrowing availability	50,000

Borrowing Base.  The availability of funds under the Iceland revolving credit facility is limited by a specified borrowing base consisting of inventory and accounts receivable of Grundartangi.

Security.  Grundartangi's obligations under the Iceland revolving credit facility are secured by a general bond under which Grundartangi's inventory and accounts receivable are pledged to secure full payment of the loan. 

Interest Rates and Fees.  Any amounts outstanding under the Iceland revolving credit facility will bear interest at LIBOR plus the margin per annum.

7.5% Notes due 2021

General.  On June 4, 2013, we issued $250,000 of our 7.5% Notes due 2021 (the "7.5% Notes") in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended.  The 7.5% Notes were issued at a discount and we received proceeds of $246,330, prior to payment of financing fees and related expenses.

Interest rate.  The 7.5% Notes bear interest at 7.5% per annum on the principal amount,payable semi-annually in arrears in cash on June 1 and December 1 of eachyear.

Maturity.  The 7.5% Notes mature on June 1, 2021. 

E.ON contingent obligation

The E.ON contingent obligation consists of the aggregate E.ON payments made to Big Rivers Electric Corporation ("Big Rivers") on CAKY’s behalf in excess of the agreed upon base amount under the long-term cost-based power contract with Kenergy, a member cooperative of Big Rivers (the "Big Rivers Agreement"). Our obligation to make repayments is contingent upon certain operating criteria for Hawesville and the LME price of primary aluminum. When the conditions for repayment are met, and for so long as those conditions continue to be met, we will be obligated to make principal and interest payments, in up to 72 monthly payments.

Based on the LME forward market prices for primary aluminum at June 30, 2014 and management's estimate of the LME forward market for periods beyond the quoted periods, we recognized a derivative asset which offsets our contingent obligation. As a result, our net liability decreased and we recorded a gain of $706 and $16,075 in net gain (loss) on forward and derivative contracts for the six months ended June 30, 2014 and 2013, respectively. In addition, we believe that we will not have any payment obligations for the E.ON contingent obligation through the term of the agreement, which expires in 2028. However, future increases in the LME forward market may result in a partial or full derecognition of the derivative asset and a corresponding recognition of a loss. The following table provides information about the balance sheet location and gross amounts offset:

10. Commitments and contingencies

Environmental Contingencies

Based upon all available information, we believe our current environmental liabilities do not have, and are not likely to have, a material adverse effect on our financial condition, results of operations or liquidity. Because of the issues and uncertainties described below and the inability to predict the requirements of future environmental laws, there can be no assurance that future capital expenditures and costs for environmental compliance at currently or formerly owned or operated properties will not result in liabilities that may have a material adverse effect on our financial condition, results of operations or liquidity.

It is our policy to accrue for costs associated with environmental assessments and remedial efforts when it becomes probable that a liability has been incurred and the costs can be reasonably estimated. The aggregate environmental-related accrued liabilities were $1,228 and $999 at June 30, 2014 and December 31, 2013, respectively. All accrued amounts have been recorded without giving effect to any possible future recoveries. With respect to costs for ongoing environmental compliance, including maintenance and monitoring, such costs are expensed as incurred.

Century Aluminum of West Virginia ("CAWV") continues to perform monitoring activities at our Ravenswood, West Virginia facility pursuant to an order issued by the United States Environmental Protection Agency (the "EPA") in 1994 (the "3008(h) Order").  In compliance with the 3008(h) Order, CAWV conducted a RCRA facility investigation ("RFI") evaluating other areas at Ravenswood that may have contamination requiring remediation. The RFI has been approved by appropriate agencies.  CAWV has completed interim remediation measures at two sites identified in the RFI, and we believe no further remediation will be required. A final order approving CAWV's Corrective Measures Study, which formally documents the conclusion of these activities, has been issued by the EPA. Under the order, CAWV's responsibilities going forward include monitoring specific wells as well as restricting access to certain parts of the site. 

Prior to our purchase of Hawesville, the EPA issued a final Record of Decision ("ROD") under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"). By agreement, Southwire Company ("Southwire"), the former owner and operator of Hawesville, is required to perform all obligations under the ROD.  CAKY has agreed to operate and maintain the ground water treatment system required under the ROD on behalf of Southwire, and Southwire will reimburse CAKY for any expense that exceeds $400 annually. The groundwater treatment system ceased operations in May 2010 and was decommissioned and removed from the site in 2012. Quarterly monitoring of specific wells is ongoing.

In July 2006, we were named as a defendant, together with certain affiliates of Alcan Inc., in a lawsuit brought by Alcoa Inc. seeking to determine responsibility for certain environmental indemnity obligations related to the sale of a cast aluminum plate manufacturing facility located in Vernon, California, which we purchased from Alcoa Inc. in December 1998, and sold to Alcan Rolled Products-Ravenswood LLC in July 1999. The complaint also seeks costs and attorney fees. The matter is in a preliminary stage in the U.S. District Court for the District of Delaware, and we cannot predict the ultimate outcome of this action or estimate a range of possible losses related to this matter at this time.

Matters relating to the St. Croix Alumina Refining Facility

We are a party to an EPA Administrative Order on Consent (the "Order") pursuant to which certain past and present owners of an alumina refining facility at St. Croix, Virgin Islands (the "St. Croix Alumina Refinery") have agreed to carry out a Hydrocarbon Recovery Plan to remove and manage hydrocarbons floating on groundwater underlying the facility.  Pursuant to the Hydrocarbon Recovery Plan, recovered hydrocarbons and groundwater are delivered to the adjacent petroleum refinery where they are received and managed. In connection with the sale of the facility by Lockheed Martin Corporation ("Lockheed") to one of our affiliates, Virgin Islands Alumina Corporation ("Vialco"), in 1989, Lockheed, Vialco and Century entered into the Lockheed-Vialco Asset Purchase Agreement. The indemnity provisions contained in the Lockheed-Vialco Asset Purchase Agreement allocate responsibility for certain environmental matters. Lockheed has tendered indemnity to Vialco. We have likewise tendered indemnity to Lockheed. Through June 30, 2014, we have expended approximately $1,033 on the Hydrocarbon Recovery Plan.  At this time, we are not able to estimate the amount of any future potential payments under this indemnification to comply with the Order, but we do not anticipate that any such amounts will have a material adverse

effect on our financial condition, results of operations or liquidity, regardless of the final outcome. Vialco sold the St. Croix Alumina Refinery to St. Croix Alumina, LLC, a subsidiary of Alcoa in 1995.

In December 2010, Century was among several defendants named in a lawsuit filed by plaintiffs who either worked, resided or owned property in the area downwind from the St. Croix Alumina Refinery. In March 2011, Century was also named a defendant in a nearly identical suit brought by certain additional plaintiffs. The plaintiffs in both suits allege damages caused by the presence of red mud and other particulates coming from the alumina facility and are seeking unspecified monetary damages, costs and attorney fees as well as certain injunctive relief. We have tendered indemnity and defense to St. Croix Alumina LLC and Alcoa Alumina & Chemical LLC under the terms of an acquisition agreement relating to the facility and have filed motions to dismiss plaintiffs’ claims, but the Superior Court of the Virgin Islands, Division of St. Croix has not yet ruled on the motions. At this time, it is not practicable to predict the ultimate outcome of or to estimate a range of possible losses for any of the foregoing actions relating to the St. Croix Alumina Refinery.

In July 2014, we entered into a settlement (the "St. Croix Settlement") with the plantiffs in certain matters related to the St. Croix Alumina Refinery.

The first lawsuit (the "2005 Action") covered by the St. Croix Settlement was filed in May 2005 by the Commissioner of the Department of Planning and Natural Resources ("DPNR"), in his capacity as Trustee for Natural Resources of the United States Virgin Islands against Vialco and certain other named defendants.  The complaint alleged damages to natural resources caused by alleged releases from the St. Croix Alumina Refinery and the adjacent petroleum refinery.  The primary cause of action was pursuant to the natural resource damage provisions of CERCLA, but various ancillary Territorial law causes of action were included as well.  We and Lockheed each tendered indemnity and defense of the case to the other pursuant to the terms of the Lockheed-Vialco Asset Purchase Agreement.  The complaint sought unspecified monetary damages, costs and attorney fees. In November 2011, the District Court of the Virgin Islands, Division of St. Croix granted a motion by Century, dismissing Century from the case. Vialco, however, remained a defendant and asserted factual and affirmative defenses.  

The second lawsuit (the "Superior Court Action") covered by the St. Croix Settlement was filed in December 2006 by the Commissioner of the DPNR against Vialco and the succeeding owners of the St. Croix Alumina Refinery. The complaint alleged that the defendants failed to take certain actions specified in a Coastal Zone management permit issued to Vialco in October 1994, and alleged violations of territorial water pollution control laws during the various defendants’ periods of ownership. The complaint sought statutory and other unspecified monetary penalties for the alleged violations. On March 19, 2012, the plaintiff filed a motion to dismiss the settling defendants in the DPNR case described above from this action.  On May 9, 2012, the Superior Court of the Virgin Islands, Division of St. Croix granted plaintiff's motion to dismiss leaving Vialco as the only remaining defendant in this action. 

Finally, in May 2009, St. Croix Renaissance Group, L.L.L.P. ("SCRG") filed a third-party complaint (the "2009 Action") for contribution and other relief against several third-party defendants, including Century and Vialco, relating to a lawsuit filed against SCRG seeking recovery of response costs relating to the aforementioned DPNR CERCLA matter. In February 2011, the District Court of the Virgin Islands, Division of St. Croix granted a motion by Century, dismissing Century from the case. In March 2011, the court granted the remaining defendants’, including Vialco’s, motion for summary judgment, dismissing the case. The plaintiff filed a notice of appeal with the Third Circuit Court of Appeals in May 2011. On June 5, 2013, the Third Circuit Court of Appeals reversed the lower court's ruling, holding that plaintiff's expenditures of funds may be found as recoverable response costs incurred by the government entitling plaintiffs to recover future response costs. Vialco remained the only Century entity in the litigation.

Pursuant to the terms of the St. Croix Settlement, entered into as of July 7, 2014 by and among Vialco, DPNR, the Commissioner of the DPNR and the Government of the Virgin Islands (the “Government”), Vialco agreed to pay $625 to the Government in consideration of full release by DPNR, the Commissioner of the DPNR and the Government from all claims asserted in and relief, including attorneys’ fees and litigation costs ever sought or which could be sought by such plaintiffs in the 2005 Action, the Superior Court Action and the 2009 Action.

Legal Contingencies

In addition to the foregoing matters, we have pending against us or may be subject to various lawsuits, claims and proceedings related primarily to employment, commercial, stockholder, safety and health matters.

In evaluating whether to accrue for losses associated with legal contingencies, it is our policy to take into consideration factors such as the facts and circumstances asserted, our historical experience with contingencies of a similar nature, the likelihood of our prevailing and the severity of any potential loss.  For some matters, no accrual is established because we have assessed our risk of loss to be remote.  Where the risk of loss is probable and the amount of the loss can be reasonably estimated, we record an accrual, either on an individual basis or with respect to a group of matters involving similar claims, based on the factors set forth above.  

When we have assessed that a loss associated with legal contingencies is reasonably possible, we determine if estimates of possible losses or ranges of possible losses are in excess of related accrued liabilities, if any.  Based on current knowledge, management has ascertained estimates for losses that are reasonably possible and management does not believe that any reasonably possible outcomes in excess of our accruals, if any, either individually or in aggregate, would be material to our financial condition, results of operations, or liquidity. We reevaluate and update our assessments and accruals as matters progress over time.

In April 2013, our subsidiary Nordural Grundartangi ehf received a ruling in an arbitration case involving two of its power suppliers, HS Orka hf ("HS") and Orkuveita Reykjavikur ("OR"). Under the arbitration award, Nordural Grundartangi ehf is restricted from reducing power under its existing power contracts with HS and OR in order to take power under a separate power contract with OR originally intended to be used at Helguvik. Nordural Grundartangi ehf remains entitled to take power under the OR Helguvik contract to the extent that its power needs exceed the amount of power provided under its existing power contracts. As part of the award, the tribunal awarded HS damages and Nordural Grundartangi ehf paid $1,470 to HS in full satisfaction of such award. The tribunal ordered each party to pay its own legal fees and costs. While no damages were awarded to OR as part of the arbitration, OR subsequently alleged damages against Nordural Grundartangi ehf.  In June 2014, we reached a settlement with OR pursuant to the terms of which, among other things, Nordural Grundartangi ehf agreed to pay $3,600 to OR and OR withdrew and released each of Nordural Grundartangi ehf and Nordural Helguvik ehf from and against all claims related to the reduction in the power purchased under the existing power contracts. This settlement amount was paid in July 2014. As part of the settlement, Nordural Helguvik ehf and OR also entered into a Supplemental Power Contract pursuant to which OR agreed to provide supplemental power to Grundartangi or Helguvik from time to time during the remaining term of the existing Nordural Helguvik ehf power contract with OR.

Ravenswood Retiree Medical Benefits changes

In November 2009, CAWV filed a class action complaint for declaratory judgment against the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union ("USWA"), the USWA’s local and certain CAWV retirees, individually and as class representatives, seeking a declaration of CAWV’s rights to modify/terminate retiree medical benefits.  Later in November 2009, the USWA and representatives of a retiree class filed a separate suit against CAWV, Century Aluminum Company, Century Aluminum Master Welfare Benefit Plan, and various John Does with respect to the foregoing.  These actions, entitled Dewhurst, et al. v. Century Aluminum Co., et al., and Century Aluminum of West Virginia, Inc. v. United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union, AFL-CIO/CLC, et al., have been consolidated and venue has been set in the District Court for the Southern District of West Virginia. In January 2010, the USWA filed a motion for preliminary injunction to prevent us from implementing any modifications to the retiree medical benefits while these lawsuits are pending, which was dismissed by the trial court, and affirmed upon appeal. CAWV has filed a motion for summary judgment of these actions. The case in chief is currently proceeding in the trial court, subject to the court’s ruling on the motion for summary judgment.

PBGC Settlement

In June 2011, the Pension Benefit Guaranty Corporation (the "PBGC") informed us that it believed a "cessation of operations" under ERISA had occurred at our Ravenswood facility as a result of the curtailment of operations at the facility. Although we disagree that a "cessation of operations" occurred, we entered into a settlement agreement with the PBGC in April 2013 to resolve the matter. Pursuant to the terms of the agreement, we will make additional contributions (above any minimum required contributions) to our defined benefit pension plans totaling approximately $17,400 over the term of the agreement. During 2013, we made contributions pursuant to this agreement of approximately $6,700. Under certain circumstances, in periods of lower primary aluminum prices relative to our cost of 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 the first quarter of 2014, we elected to defer contributions for 2014 under the PBGC agreement and have provided the PBGC with the appropriate security.

Power Commitments

Hawesville

In August 2012, CAKY issued a 12-month notice to terminate its long-term power supply arrangement with Kenergy. Pursuant to the termination notice, the Hawesville Power Agreement terminated on August 20, 2013.  

Effective August 20, 2013, the Kentucky Public Service Commission ("KPSC") approved a power supply arrangement with Kenergy and 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 them. 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.

Sebree

 In January 2013, Sebree (then still owned by RTA) issued a 12-month notice to terminate its long-term power supply agreement (the "Sebree Power Agreement") with Kenergy. Pursuant to the termination notice, the Sebree Power Agreement terminated on January 31, 2014.

Effective February 1, 2014, the KPSC approved a new 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 them. 

Mt. Holly

Mt. Holly has a power purchase agreement (the "Santee Cooper Agreement") with the South Carolina Public Service Authority ("Santee Cooper") with a term through December 2015.  The Santee Cooper 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 Santee Cooper Agreement restricts Mt. Holly’s ability to reduce its power consumption (or the associated payment obligations) below contracted levels and to terminate the agreement, unless, in each case, the LME falls below certain negotiated levels.

In 2012, Mt. Holly and Santee Cooper amended the terms of the Santee Cooper Agreement in order to allow Mt. Holly to receive all or a portion of Mt. Holly's 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, among other factors, on the cost of natural gas rather than Santee Cooper's system average fuel costs, which are primarily coal-based. The amended power agreement provides that Mt. Holly may continue to receive its supplemental power requirements from the off-system facility through December 31, 2015.

On June 30, 2014, Mt. Holly gave notice to Santee Cooper under the Santee Cooper Agreement to reduce the contact 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. 

Ravenswood

CAWV has a power purchase agreement (the "APCo Agreement") with the Appalachian Power Company ("APCo").  CAWV currently purchases a limited amount of power under the APCo Agreement as necessary to maintain its Ravenswood smelter, which is presently curtailed.  Power is supplied under the APCo Agreement at prices set forth in published tariffs (which are subject to change), with certain adjustments.   

Grundartangi

Nordural Grundartangi ehf has power purchase agreements with HS, Landsvirkjun and OR to provide power to its Grundartangi smelter.  These power purchase agreements, which will expire on various dates from 2019 through 2036, provide power at LME-based variable rates.  Each power purchase agreement contains take-or-pay obligations with respect to a significant percentage of the total committed and available power under such agreement.

In the fourth quarter of 2011, an additional 47.5 MW of power became available under a power purchase agreement with OR. This power can be used at either Grundartangi or Helguvik and is currently being utilized at Grundartangi.

In June 2012, Nordural Grundartangi ehf entered into a 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 June 30, 2014, these power prepayments totaled approximately $2,000. We do not expect the amount of the prepayment to grow any higher, but we do not expect to realize the benefits from the prepayments in the near term.

Helguvik

Nordural Helguvik ehf has power purchase agreements with HS and OR to provide power to the Helguvik project.  These power purchase agreements provide power at LME-based variable rates and contain take-or-pay obligations with respect to a significant percentage of the total committed and available power under such agreements.  The first stage of power under the OR power purchase agreement (approximately 47.5 MW) became available in the fourth quarter of 2011 and is currently being utilized at Grundartangi. 

The power purchase agreements with HS and OR to provide power to Helguvik 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.  Nordural Helguvik ehf is in discussions with both HS and OR with respect to such conditions and other matters pertaining to these agreements. See Note 18 Subsequent events for additional information concerning these discussions.

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.

16. Recently issued accounting standards updates

In May 2014, the FASB and 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.

The core principal of the new revenue model is that "an entity recognizes revenue for the transfer of promised goods and services to customers in the amount that reflects the expected consideration for those goods and services." When applying the revenue model to contracts within the scope of the ASU, an entity:

• identifies the contract with a customer

• identifies the performance obligations in the contract

• determines the transaction price

• allocates the transaction price to the performance obligations in the contract

• recognizes revenue when (or as) the entity satisfies the performance obligations.

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.

17. Condensed consolidating financial information

Our 7.5% Notes due 2014 are guaranteed by each of our material existing and future domestic subsidiaries, except for Nordural US LLC (collectively, the "Guarantor Subsidiaries"). The Guarantor Subsidiaries are 100% owned by Century Aluminum Company (the "Company"). All guarantees are full and unconditional; all guarantees are joint and several. These notes are not guaranteed by our foreign subsidiaries (such subsidiaries and Nordural US LLC, collectively the "Non-Guarantor Subsidiaries"). We allocate corporate expenses or income to our subsidiaries and charge interest on certain intercompany balances.

The following summarized condensed consolidating balance sheets as of June 30, 2014 and December 31, 2013, condensed consolidating statements of comprehensive income (loss) for the three and six months ended June 30, 2014 and 2013 and the condensed consolidating statements of cash flows for the six months ended June 30, 2014 and 2013 present separate results for Century, the Guarantor Subsidiaries, the Non-Guarantor Subsidiaries, consolidating adjustments and total consolidated amounts.

This summarized condensed consolidating financial information may not necessarily be indicative of the results of operations, financial position or cash flows had the Company, the Guarantor Subsidiaries or the Non-Guarantor Subsidiaries operated as independent entities.

Six months ended June 30,	$	879.2	$	653.2	$	226.0	34.6	%

In the three months ended June 30, 2014, higher shipment volumes, due to the acquisition of the Sebree smelter on June 1, 2013 and the replacement of a tolling contract that expired December 31, 2013 with a direct sale contract at Grundartangi, had a $115.1 million positive impact on net sales. Direct shipments from our four operating smelters increased 76,748 tonnes in the three months ended June 30, 2014 compared to the same period in 2013. Toll shipments decreased 36,974 tonnes relative to the

38

same period last year. Higher price realizations for our primary aluminum shipments in the three months ended June 30, 2014 were due to higher regional and product premiums, which more than offset lower LME prices for primary aluminum. The higher price realizations resulted in a $11.3 million increase in sales.

In the six months ended June 30, 2014, higher shipment volumes, due to the acquisition of the Sebree smelter on June 1, 2013 and the replacement of a tolling contract that expired December 31, 2013 with a direct sale contract at Grundartangi, had a $251.3 million positive impact on net sales. Direct shipments from our four operating smelters increased 156,572 tonnes in the six months ended June 30, 2014 compared to the same period in 2013. Toll shipments decreased 68,789 tonnes relative to the same period last year. Lower price realizations for our primary aluminum shipments in the six months ended June 30, 2014 were due to lower LME prices for primary aluminum which were partially offset by higher regional and product premiums. The lower price realizations resulted in a $25.3 million decrease in sales.

Gross profit (loss) (in millions)	2014		2013			$ Difference		% Difference

Six months ended June 30,	$	36.7	$	11.9		$	24.8	208.4	%

During the three months ended June 30, 2014, higher price realizations, net of LME-based power cost and alumina, increased gross profit by $22.9 million, while increased volume due to the acquisition of the Sebree smelter and the mix shift between toll and direct sales at Grundartangi increased gross profit by $2.2 million. In addition, we experienced $11.5 million in net cost decreases at our smelters relative to the same period in 2013, comprised of: lower costs for power and natural gas at our U.S. smelters, $13.0 million; lower costs for materials, supplies and maintenance, $2.7 million; other cost increases, $2.6 million; increased depreciation, $1.1 million and an increase in our accrual for legal matters, $0.5 million.

During the six months ended June 30, 2014, lower price realizations, net of LME-based power cost and alumina, decreased gross profit by $1.3 million, while increased volume due to the acquisition of the Sebree smelter and the mix shift between toll and direct sales at Grundartangi increased gross profit by $7.2 million. In addition, we experienced $1.2 million in net cost increases at our smelters relative to the same period in 2013, comprised of: lower costs for power and natural gas costs at our U.S. smelters, $1.8 million; lower costs for materials, supplies and maintenance, $6.4 million; other cost increases, $2.6 million; increased depreciation, $3.2 million and an increase in our accrual for legal matters, $3.6 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 the three and six months ended June 30, 2013, the credit for the amortization of the power contract was $2.7 million. During the three and six months ended June 30, 2014, the credit for the amortization of the power contract was $0.0 million and $5.5 million, respectively. This resulted in a quarter to quarter decrease in gross profit of $2.7 million and six month period to period increase in gross profit of $2.8 million.

As of June 30, 2014, the market value of our inventory was above its cost basis, resulting in the release of a lower of cost or market (“LCM”) inventory reserve of $0.1 million that was recorded at March 31, 2014. This resulted in a credit to cost of goods sold for the three months ended June 30, 2014 of $0.1 million. As of June 30, 2013, the market value of our inventory was below its cost basis, resulting in the recording of an LCM inventory reserve of $16.1 million and a charge to cost of goods sold for the three months ended June 30, 2013 of $10.2 million. This resulted in a quarter to quarter increase in gross profit of $10.3 million.

As of June 30, 2014, the market value of our inventory was above its cost basis, resulting in the release of an LCM inventory reserve of $1.2 million that was recorded at December 31, 2013. This resulted in a credit to cost of goods sold for the six months ended June 30, 2014 of $1.2 million. As of June 30, 2013, the market value of our inventory was below its cost basis, resulting in the recording of an LCM inventory reserve of $16.1 million and a charge to cost of goods sold for the six months ended June 30, 2013 of $16.1 million. This resulted in a period to period increase in gross profit of $17.3 million.

Six months ended June 30,	$	4.3	$	4.1	$	0.2		4.9	%

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 addition, in the first quarter of 2013 we reduced an accrual for a legal liability that was ultimately settled for an amount lower than the original accrual.

Selling, general and administrative expenses (in millions)	2014		2013		$ Difference			% Difference

Six months ended June 30,	$	20.7	$	31.5	$	(10.8	)	(34.3	)%

During the three and six months ended June 30, 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 addition, we incurred $5.3 million of general and administrative expenses that were evenly spread 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 (in millions)	2014			2013		$ Difference			% Difference

Six months ended June 30,	$	(0.5	)	$	15.7	$	(16.2	)	(103.2	)%

The net gain (loss) on forward and derivative contracts for the six months ended June 30, 2014 was primarily the result of settlements of contracts put in place to provide partial downside price protection for our domestic facilities. As of March 31, 2014, all of these contracts were settled.

The net gain (loss) on forward and derivative contracts for the six months ended June 30, 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 $16.1 million for the six months ended June 30, 2013.

Gain on bargain purchase (in millions)	2014		2013		$ Difference			% Difference

Six months ended June 30,	$	—	$	5.3	$	(5.3	)	N/A

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. We have finalized the purchase price allocation for the assets acquired and liabilities assumed, the purchase price and gain on bargain purchase. Based on the final purchase price allocation, we recorded a gain on bargain purchase of $5.3 million in 2013. See Note 2 Acquisition of Sebree aluminum smelter to the consolidated financial statements included herein for additional information.

Loss on early extinguishment of debt (in millions)	2014		2013			$ Difference		% Difference

Six months ended June 30,	$	—	$	(3.3	)	$	3.3	N/A

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

40

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 (in millions)	2014			2013			$ Difference			% Difference
Three months ended June 30,	$	(1.7	)	$	(0.8	)	$	(0.9	)	112.5	%
Six months ended June 30,	$	(0.6	)	$	(3.3	)	$	2.7		(81.8	)%

Our income tax expense is based on a forecasted annual effective tax rate applied to current period results, as well as the tax effects of certain discrete items. The application of the requirements for accounting for income taxes in interim periods, after consideration of our valuation allowance against all of Century's U.S. and certain foreign deferred tax assets, can cause significant variations in the typical relationship between income tax expense and pretax income.

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 June 30, 2014 was approximately $61 million compared to approximately $84 million at December 31, 2013. Century's U.S. revolving credit facility matures in May 2018 and our Iceland revolving credit facility matures in November 2016. As of June 30, 2014, our credit facilities had no outstanding borrowings and approximately $129 million of aggregate net availability. As of June 30, 2014, we had approximately $71 million of letters of credit outstanding under our U.S. revolving credit facility. 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 six months ended June 30, 2014 on a gross basis were approximately $86.6 million and $92.6 million, respectively. During the same period, total outstanding indebtedness under our credit facilities at any given time did not exceed $16.7 million. The availability of funds under our credit facilities is limited by a specified borrowing base consisting of certain accounts receivable and inventory. Future changes to our sales agreements which have shorter payment terms could reduce our accounts receivable. In addition, any future curtailments of production capacity would reduce accounts receivable and inventory, which comprise the borrowing base of our revolving credit facilities, and could result in a corresponding reduction in availability under the revolving credit facilities. The acquisition of the Sebree smelter increased domestic accounts receivable and inventory and resulted in a corresponding increase in availability under the U.S. revolving credit facility.

We have $250 million in 7.5% senior secured notes payable that will mature on June 1, 2021. Our remaining 7.5% senior unsecured notes due August 2014 will reach maturity this year, and we expect to make a $2.6 million repayment to retire these notes in the third quarter of 2014.

As of June 30, 2014, the principal and accrued interest for the E.ON contingent obligation was $17.5 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 June 30, 2014 and management’s estimate of the LME forward market beyond the quoted market period, we currently believe 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 4 Derivative and hedging instruments and Note 9 Debt to the consolidated financial statements included herein for additional information.

In August 2011, our Board of Directors approved a $60 million common stock repurchase program. Through June 30, 2014, we had expended approximately $50 million under the program, but no repurchases have been made since March 2012.

41

At June 30, 2014, we had approximately $10 million remaining under the repurchase program authorization. The repurchase program may be suspended or discontinued by our Board, in its sole discretion, at any time.

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 lower primary aluminum prices relative to our cost of 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 the first quarter of 2014, 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 $4.6 million and $1.8 million, respectively, during 2014. We may choose to make additional contributions to these plans from time to time at our discretion.

In May 2014, we received a one-time payment of approximately $5.5 million from receivables related to adjustments under our Hawesville and Sebree power contracts.

In May 2014, we paid Icelandic withholding taxes on intercompany dividends of approximately $2.8 million and we expect to pay another approximately $2.8 million in August 2014. We anticipate both payments will be refunded in November 2015. In November 2014, we expect to receive a refund for Icelandic withholding taxes paid in 2013 of $9.8 million. The withholding taxes and associated refunds are payable in ISK and we are subject to foreign currency risk associated with fluctuations in the value of the U.S. dollar as compared the ISK.

On June 1, 2013, we acquired the Sebree aluminum smelter from a subsidiary of RTA. In July 2014, we received an arbitration ruling that established thefinal determination of the applicable working capital adjustments for the Sebree acquisition. As a result of this determination, we will pay RTA approximately $1.0 million in the third quarter of 2014 as final consideration for the acquisition.

In June 2014, we reached a settlement with Orkuveita Reykjavikur ("OR") related to a power contract dispute. Under the agreement, among other things, Nordural Grundartangi ehf paid $3.6 million to OR in July 2014 and OR will release Nordural Grundartangi ehf and Nordural Helguvik ehf from and against all claims related to the reduction in the power purchased under the existing power contracts. As part of the settlement, Nordural Helguvik ehf and OR entered into a supplemental power contract to provide power at LME-based rates, and as may be requested from Grundartangi or Helguvik from time to time, during the remaining term of the existing Nordural Helguvik ehf power contract. Power provided under the supplemental power contract may be used at Helguvik or Grundartangi.

In June 2012, Nordural Grundartangi ehf entered into a 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 June 30, 2014, these power prepayments totaled approximately $2.0 million. We do not expect to make any additional prepayments in connection with this agreement.

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.

42

Capital expenditures for the six months ended June 30, 2014 were $24.2 million, of which approximately $7.4 million was related to the Grundartangi expansion project and $7.2 million was related to the Century Vlissingen restart. The remaining amounts are related to upgrading production equipment, improving facilities and complying with environmental requirements. We believe capital spending in 2014, excluding any expansion of the current production capacity at Century Vlissingen, will be approximately $50 to $60 million.

In order to restart the first 75,000 tonnes of annual anode capacity at Century Vlissingen, we have made approximately $25.4 million in aggregate capital expenditures through June 30, 2014. The first 75,000 tonnes of capacity was restarted in late 2013 and provides an anode supply to Grundartangi to replace third-party anode supply contracts that terminated in 2013. We may increase production capacity to 150,000 tonnes when we conclude it is feasible and advantageous to do so.

We have made and continue to make capital expenditures for the construction and development of our Helguvik project. We have substantial future contractual commitments for the Helguvik project. If we were to cancel the Helguvik project, we estimate that our exposure to contract cancellation and other costs would be approximately $20 million, of which we currently have accrued liabilities of approximately $13.4 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. We cannot, at this time, predict when the restart of major construction activity will occur.

Adjusted Operating Income (Loss)

We use certain non-GAAP measures when reviewing our operating results, including adjusted operating income (loss). We define adjusted operating income (loss) 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 operating income (loss) 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 operating income (loss) 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 operating income (loss) 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 operating income (loss) to operating income (loss), the most comparable GAAP financial measure.

Historical

Our statements of cash flows for the six months ended June 30, 2014 and 2013 are summarized below:

	Six months ended June 30,
	2014			2013
	(in thousands)
Net cash provided by operating activities	$	8,628		$	22,976
Net cash used in investing activities	(25,458		)	(71,057		)
Net cash used in financing activities	(5,874		)	(8,364		)
Change in cash and cash equivalents	$	(22,704	)	$	(56,445	)

Net cash provided by operating activities for the six months ended June 30, 2014 was $8.6 million, compared to net cash provided by operating activities of $23.0 million for the six months ended June 30, 2013. The decrease in cash provided by operating activities in 2014 compared to 2013 was primarily due to cash used for changes in working capital and other items which was approximately $35 million higher in 2014 compared to 2013 and a separation payment to our former CEO of approximately $10 million in 2014. The decrease in cash provided by operating activities was partially offset by our adjusted operating income which was $24.4 million higher in 2014 compared to 2013. In addition, contributions to our pension plans were approximately $5 million lower in 2014 compared to 2013; cash paid for interest was approximately $2 million lower in 2014 compared to 2013 (due to the debt refinancing and lower interest rates), and; net cash paid for income/withholding taxes was approximately $1 million lower in 2014 compared to 2013.

Our net cash used in investing activities for the six months ended June 30, 2014 was $25.5 million, compared to $71.1 million for the six months ended June 30, 2013. The decrease in cash used was primarily due to payments of $48.0 million for the purchase of the Sebree smelter in June 2013 and higher capital expenditures for the Helguvik project for the six months ended June 30, 2013 compared to the same period in 2014. The decrease was partially offset by $3.5 million higher capital expenditures for the Vlissingen restart project for the six months ended June 30, 2014 compared to 2013 and slightly higher restricted cash deposits of $0.6 million in 2014.

Our net cash used in financing activities for the six months ended June 30, 2014 was $5.9 million, which was primarily related to net repayments under our revolving credit facilities of $6.0 million, compared to net cash used of $8.4 million for the six months ended June 30, 2013, which was primarily related to the net costs associated with the extinguishment of our 8.0% Notes and the issuance of our 7.5% Notes due 2021 (the "7.5% Notes").

Other Commitments and Contingencies

We are a defendant in several actions relating to various aspects of our business. While there are uncertainties relating to the ultimate disposition of any litigation, management, based on information currently available, does not believe that the resolution of 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 10 Commitments and contingencies to the consolidated financial statements included herein for additional information.

Item 3. 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.

Apart from the Glencore Grundartangi Metal Agreement, the Southwire Metal Agreement 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:

We had no outstanding primary aluminum forward financial sales contracts at June 30, 2014. We had no fixed price forward financial contracts to purchase aluminum at June 30, 2014.

Market-Based Power Price Sensitivity

Market-Based Electrical Power Agreement

Hawesville and Sebree terminated their long-term cost-based electrical power agreements with Kenergy and Big Rivers in August 2013 and January 2014, respectively. The KPSC has approved new power supply agreements with Kenergy and Big Rivers to provide market-based electrical power to the Hawesville smelter, effective August 20, 2013 and to the Sebree smelter, effective February 1, 2014. Under the market-based power agreements, Kenergy and Big Rivers 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.

Electrical Power Price Sensitivity

We are exposed to market price risk 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-based power could significantly impact the profitability of Hawesville and Sebree. In addition, indirect factors that lead to power cost increases, such as increasing market prices for natural gas or coal, fluctuations in or extremes in weather patterns, new or more stringent environmental regulations, or problems associated with power transmission, grid stability or energy import capability may severely impact our financial condition, results of operations and liquidity.

Electrical power price sensitivity by location:
	Hawesville		Sebree		Total

Quarterly estimated electrical power usage (in megawatt hours ("MWh"))	1,055,580		843,150		1,898,730

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 Century Vlissingen in future periods. In addition, Century 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 June 30, 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.

Item 4. Controls and Procedures.

a. Evaluation of Disclosure Controls and Procedures

As of June 30, 2014, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures. Based upon that evaluation, our management, including the Chief Executive Officer and Chief Financial Officer, has concluded that our disclosure controls and procedures were effective as of June 30, 2014.

b. Changes in Internal Control over Financial Reporting

During the three months ended June 30, 2014, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. On June 1, 2013, we acquired the Sebree smelter and we are currently in the process of extending our internal control over financial reporting to Sebree's operations.

47

PART II – OTHER INFORMATION

Item 1. Legal Proceedings.

We are a party from time to time in various legal actions arising in the normal course of business, the outcomes of which, in the opinion of management, neither individually nor in the aggregate are likely to result in a material adverse effect on our financial position, operating results and cash flows. For information regarding legal proceedings pending against us at June 30, 2014, refer to Note 10 Commitments and contingencies to the consolidated financial statements included herein.

Item 1A. Risk Factors.

Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2013 sets forth information relating to important risks and uncertainties that could materially adversely affect our business, financial condition or operating results. Those risk factors continue to be relevant to an understanding of our business, financial condition and operating results for the quarter ended June 30, 2014. There have been no material changes to the risk factors contained in our Annual Report on Form 10-K for the year ended December 31, 2013. You should be aware that these risk factors and other information may not describe every risk facing Century. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Fair Value Disclosures [Abstract]

Fair value measurements

Fair value measurements

The following section describes the valuation methodology used to measure our financial assets and liabilities that were accounted for at fair value and are categorized based on the fair value hierarchy described in ASC 820 "Fair Value Measurements and Disclosures."

Overview of Century’s valuation methodology
	Level	Significant inputs
Cash equivalents	1	Quoted market prices
Trust assets (1)	1	Quoted market prices
Surety bonds	1	Quoted market prices
E.ON ("E.ON") contingent obligation	3	Quoted London Metal Exchange ("LME") forward market, management’s estimates of the LME forward market prices for periods beyond the quoted periods and management’s estimate of future level of operations at Century Aluminum of Kentucky, our wholly owned subsidiary ("CAKY")
Primary aluminum sales contract	3	Management’s estimates of future U.S. Midwest premium and risk-adjusted discount rates
Midwest premium contracts	3	Management’s estimates of future U.S. Midwest premium

(1) Trust assets are currently invested in money market funds. These trust assets are held to fund the non-qualified supplemental executive pension benefit obligations for certain of our officers. The trust has sole authority to invest the funds in secure interest producing investments consisting of short-term securities issued or guaranteed by the United States government or cash and cash equivalents.

Fair value measurements

Our fair value measurements include the consideration of market risks that other market participants might consider in pricing the particular asset or liability, specifically non-performance risk and counterparty credit risk. Consideration of the non-performance risk and counterparty credit risk are used to establish the appropriate risk-adjusted discount rates used in our fair value measurements.

The following table sets forth our financial assets and liabilities that were accounted for at fair value on a recurring basis by the level of input within the ASC 820 fair value hierarchy.  As required by generally accepted accounting principles in the United States ("GAAP") for fair value measurements and disclosures, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.  Our assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and the placement within the fair value hierarchy levels. There were no transfers between Level 1 and 2 during the periods presented. There were no transfers into or out of Level 3 during the periods presented. It is our policy to recognize transfers into and transfers out of Level 3 as of the actual date of the event or change in circumstances that caused the transfer.

Acquisition of Sebree aluminum smelter

6 Months Ended

Business Combinations [Abstract]

Acquisition of Sebree aluminum smelter

Acquisition of Sebree aluminum smelter

On June 1, 2013, our wholly owned subsidiary, Century Aluminum Sebree LLC ("Century Sebree"), acquired the Sebree aluminum smelter ("Sebree") from a subsidiary of Rio Tinto Alcan, Inc. ("RTA"). Sebree, located in Robards, Kentucky, has an annualized hot metal production capacity of 205,000 tonnes of primary aluminum and employs approximately 500 people. The purchase price for the acquisition was $61,000 (subject to customary working capital adjustments), of which we have paid approximately $48,000 as of June 30, 2014. 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, subsequent to the end of the quarter, we reached the final determination of the working capital adjustments, resulting in a final purchase price for the acquisition of $49,035. See Note 18 Subsequent events for additional information.

Purchase Price Allocation

Allocating the purchase price to the acquired assets and liabilities involves management judgment. We allocated the purchase price to the assets acquired, liabilities assumed, and the gain on bargain purchase in accordance with ASC 805.

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. We have finalized the purchase price allocation for the assets acquired and liabilities assumed, the purchase price and gain on bargain purchase.

Based on the purchase price allocation, we recorded a gain on bargain purchase of $5,253 in 2013. The following table summarizes the fair value of the assets acquired and the liabilities assumed as of the acquisition date:

	Acquisition Date Fair Value as of June 30, 2014
Consideration:
Cash	$	48,083
Deferred purchase price	1,910
Assets Acquired:
Inventories	59,018
Prepaid and other current assets	2,273
Property, plant and equipment – net	55,520
Total assets acquired	$	116,811
Liabilities Assumed:
Accrued and other current liabilities	$	43,316
Accrued pension benefit costs	996
Accrued post retirement benefit costs	6,544
Other liabilities	7,476
Deferred taxes	3,233
Total liabilities assumed	$	61,565
Gain on bargain purchase:	$	5,253

The following unaudited pro forma financial information for the three and six months ended June 30, 2013 reflects our results of continuing operations as if the acquisition of Sebree had been completed on January 1, 2013. This unaudited pro forma financial information is provided for informational purposes only and is not necessarily indicative of what the actual results of operations would have been had the transactions taken place on January 1, 2013, nor is it indicative of the future consolidated results of operations or financial position of the combined companies.

	Three months ended June 30,			Six months ended June 30,
	2013			2013
Pro forma revenues	$	413,907		$	861,605
Pro forma loss from continuing operations	(36,253		)	(37,205		)
Loss per common share, basic	(0.41		)	(0.42		)
Loss per common share, diluted	(0.41		)	(0.42		)

Our net income for the six months ended June 30, 2014 includes a non-recurring credit for the amortization of the deferred power contract liability of $5,534 related to the amortization of an unfavorable power contract assumed as part of the Sebree acquisition resulting in a credit to our depreciation and amortization expense within cost of goods sold on the consolidated statement of operations for the first quarter of 2014. The power contract terminated on January 31, 2014.

New Accounting Pronouncement or Change in Accounting Principle, Current Period Disclosures [Abstract]

Recently issued accounting standards updates

Recently issued accounting standards updates

In May 2014, the FASB and 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.

The core principal of the new revenue model is that "an entity recognizes revenue for the transfer of promised goods and services to customers in the amount that reflects the expected consideration for those goods and services." When applying the revenue model to contracts within the scope of the ASU, an entity:

• identifies the contract with a customer

• identifies the performance obligations in the contract

• determines the transaction price

• allocates the transaction price to the performance obligations in the contract

• recognizes revenue when (or as) the entity satisfies the performance obligations.

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.

As a producer of primary aluminum, we are exposed to fluctuating raw material and primary aluminum prices. From time to time we enter into fixed and market priced contracts for the sale of primary aluminum and the purchase of raw materials in future periods.

Forward Physical Delivery Agreements

Stockholders' Equity Note [Abstract]

Shareholders' equity

Shareholders’ equity

Common Stock

Under our Restated Certificate of Incorporation, our Board of Directors is authorized to issue up to 195,000,000 shares of our common stock.

The rights, preferences and privileges of holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock which are currently outstanding, including our Series A Convertible Preferred Stock, or which we may designate and issue in the future.

Stock Repurchase Program

In August 2011, our Board of Directors approved a stock repurchase program. Under the program, we may repurchase up to $60,000 of our outstanding shares of common stock from time to time on the open market at prevailing market prices, in block trades or otherwise. The timing and amount of any shares repurchased is determined by our management based on its evaluation of market conditions, the trading price of the stock and other factors. The repurchase program may be suspended or discontinued at any time.

Shares of common stock repurchased are recorded at cost as treasury stock and result in a reduction of shareholders’ equity in the consolidated balance sheets. From time to time, treasury shares may be reissued as contributions to our employee benefit plans and for the conversion of convertible preferred stock. When shares are reissued, we use an average cost method for determining cost. The difference between the cost of the shares and the reissuance price is added to or deducted from additional paid-in capital.

From August 11, 2011 through June 30, 2014, we repurchased 4,786,521 shares of common stock for an aggregate purchase price of $49,924. We have made no repurchases since March 2012 and had approximately $10,076 remaining under the repurchase program authorization as of June 30, 2014.

Series A Convertible Preferred Stock

Glencore holds all of the issued and outstanding Series A Convertible Preferred Stock. The issuance of common stock under our stock incentive programs, debt exchange transactions and any stock offering that excludes Glencore participation triggers anti-dilution provisions of the preferred stock agreement and results in the automatic conversion of Series A Convertible Preferred Stock shares into shares of common stock. The Common and Preferred Stock Activity table below contains additional information about preferred stock conversions during the six months ended June 30, 2014 and 2013.

Common and Preferred Stock Activity:	Preferred stock		Common stock
(in shares)	Series A convertible		Treasury	Outstanding

Earnings per share

Earnings Per Share [Abstract]

Earnings (loss) per share

Earnings (loss) per share

Basic earnings (loss) per share ("EPS") amounts are calculated by dividing earnings 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 and we calculate the amount of earnings (loss) available to common shareholders 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.

The following table shows the basic and diluted earnings (loss) per share for the three and six months ended June 30, 2014 and 2013:

	For the three months ended June 30,
	2014						2013
	Income			Shares (000)	Per-Share		Loss			Shares (000)	Per-Share
Net income (loss)	$	20,344					$	(29,384	)
Amount allocated to common stockholders (1)	91.80		%				100		%
Basic EPS:
Income (loss) allocable to common stockholders	18,675			88,787	$	0.21	(29,384		)	88,597	$	(0.33	)
Effect of Dilutive Securities:
Share-based compensation plans	—			565			—			—
Diluted EPS:
Income (loss) applicable to common stockholders with assumed conversion	$	18,675		89,352	$	0.21	$	(29,384	)	88,597	$	(0.33	)
	For the six months ended June 30,
	2014						2013
	Income			Shares (000)	Per-Share		Loss			Shares (000)	Per-Share
Net income (loss)	$	240					$	(21,131	)
Amount allocated to common stockholders (1)	91.78		%				100		%
Basic EPS:
Income (loss) allocable to common stockholders	220			88,752	$	0.00	(21,131		)	88,576	$	(0.24	)
Effect of Dilutive Securities:

Diluted EPS:
Income (loss) applicable to common stockholders with assumed conversion	$	220		89,292	$	0.00	$	(21,131	)	88,576	$	(0.24	)

(1) We have not allocated net losses between common and preferred stockholders, as the holders of our preferred shares do not have a contractual obligation to share in the loss.

Securities excluded from the calculation of diluted EPS:	Three months ended June 30,		Six months ended June 30,
	2014	2013	2014	2013
Stock options (1)	347,433	620,334	347,433	620,334
Service-based share awards (1)	—	576,510	—	496,234

(1) In periods when we report a net loss, all share awards are excluded from the calculation of diluted weighted average shares outstanding because of their antidilutive effect on earnings (loss) per share.

	June 30, 2014		December 31, 2013

Hancock County industrial revenue bonds ("IRBs") due 2028, interest payable quarterly (variable interest rates (not to exceed 12%)) (1)	$	7,815	$	7,815
7.5% senior unsecured notes due August 15, 2014, interest payable semiannually (2)	2,603		2,603

TOTAL	$	257,123	$	262,946

(1) The IRBs are classified as current liabilities because they are remarketed weekly and could be required to be repaid upon demand if there is a failed remarketing. The IRB interest rate at June 30, 2014 was 0.26%.

(2) These items are recorded in accrued and other current liabilities based on the repayment terms and expected maturity.

(3) Borrowings under the Iceland revolving credit facility bear variable interest based on LIBOR plus the applicable margin per annum. The interest rate at December 31, 2013 was 3.92%.

U.S. Revolving Credit Facility

General.  We and certain of our direct and indirect domestic subsidiaries (together with Century, the "Borrowers") and Wells Fargo Capital Finance, LLC, as lender and agent, and Credit Suisse AG, BNP Paribas, and Morgan Stanley Senior Funding Inc., as lenders, entered into the Amended and Restated Loan and Security Agreement (the "U.S. revolving credit facility"), dated May 24, 2013, as amended, modifying our credit facility dated July 1, 2010. The U.S. revolving credit facility has a term through May 24, 2018 and provides for borrowings of up to $150,000 in the aggregate, including up to $80,000 under a letter of credit sub-facility.  Any letters of credit issued and outstanding under the U.S. revolving credit facility reduce our borrowing availability on a dollar-for-dollar basis.  

Status of our U.S. revolving credit facility:

	June 30, 2014
Credit facility maximum amount	$	150,000
Borrowing availability, net of outstanding letters of credit	79,455
Outstanding borrowings	—
Letter of credit sub-facility amount	80,000
Outstanding letters of credit issued	70,545

Borrowing Base.  The availability of funds under the U.S. revolving credit facility is limited by a specified borrowing base consisting of accounts receivable and inventory of the Borrowers which meet the eligibility criteria.  

Guaranty.  The Borrowers' obligations under the U.S. revolving credit facility are guaranteed by certain of our domestic subsidiaries and secured by a continuing lien upon and a security interest in all of the Borrowers' accounts receivable, inventory and certain bank accounts.  Each Borrower is liable for any and all obligations under the U.S. revolving credit facility on a joint and several basis.

Interest Rates and Fees.  Any amounts outstanding under the U.S. revolving credit facility will bear interest, at our option, at LIBOR or a base rate, plus, in each case, an applicable interest margin.  The applicable interest margin is determined based on the average daily availability for the immediately preceding quarter.  In addition, we pay an unused line fee on undrawn amounts, less the amount of our letters of credit exposure.  For standby letters of credit, we are required to pay a fee on the face amount that varies depending on whether the letter of credit exposure is cash collateralized.

Iceland Revolving Credit Facility

General. Nordural Grundartangi ehf, as borrower, and Landsbankinn hf., as lender, entered into a three-year $50,000 Committed Revolving Credit Facility agreement (the "Iceland revolving credit facility"), dated November 27, 2013. Grundartangi may in the future use the Iceland revolving credit facility to repay existing indebtedness or to finance capital expenditures and for ongoing working capital needs and other general corporate purposes. Under the terms of the Iceland revolving credit facility, when Grundartangi borrows funds it will designate a repayment date, which may be any date prior to the maturity of the Iceland revolving credit facility. The Iceland revolving credit facility will mature on November 27, 2016.

Status of our Iceland revolving credit facility:

	June 30, 2014
Credit Facility maximum amount	$	50,000
Borrowing availability	50,000
Outstanding borrowings	—

Borrowing Base.  The availability of funds under the Iceland revolving credit facility is limited by a specified borrowing base consisting of inventory and accounts receivable of Grundartangi.

Security.  Grundartangi's obligations under the Iceland revolving credit facility are secured by a general bond under which Grundartangi's inventory and accounts receivable are pledged to secure full payment of the loan. 

Interest Rates and Fees.  Any amounts outstanding under the Iceland revolving credit facility will bear interest at LIBOR plus the margin per annum.

7.5% Notes due 2021

General.  On June 4, 2013, we issued $250,000 of our 7.5% Notes due 2021 (the "7.5% Notes") in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended.  The 7.5% Notes were issued at a discount and we received proceeds of $246,330, prior to payment of financing fees and related expenses.

Interest rate.  The 7.5% Notes bear interest at 7.5% per annum on the principal amount,payable semi-annually in arrears in cash on June 1 and December 1 of eachyear.

Maturity.  The 7.5% Notes mature on June 1, 2021. 

E.ON contingent obligation

The E.ON contingent obligation consists of the aggregate E.ON payments made to Big Rivers Electric Corporation ("Big Rivers") on CAKY’s behalf in excess of the agreed upon base amount under the long-term cost-based power contract with Kenergy, a member cooperative of Big Rivers (the "Big Rivers Agreement"). Our obligation to make repayments is contingent upon certain operating criteria for Hawesville and the LME price of primary aluminum. When the conditions for repayment are met, and for so long as those conditions continue to be met, we will be obligated to make principal and interest payments, in up to 72 monthly payments.

Based on the LME forward market prices for primary aluminum at June 30, 2014 and management's estimate of the LME forward market for periods beyond the quoted periods, we recognized a derivative asset which offsets our contingent obligation. As a result, our net liability decreased and we recorded a gain of $706 and $16,075 in net gain (loss) on forward and derivative contracts for the six months ended June 30, 2014 and 2013, respectively. In addition, we believe that we will not have any payment obligations for the E.ON contingent obligation through the term of the agreement, which expires in 2028. However, future increases in the LME forward market may result in a partial or full derecognition of the derivative asset and a corresponding recognition of a loss. The following table provides information about the balance sheet location and gross amounts offset:

Income taxes

We recorded income tax expense for the six months ended June 30, 2014 of $560, which primarily consisted of foreign and state income taxes. Our domestic deferred tax assets, net of deferred tax liabilities, are subject to a valuation allowance; therefore, the domestic losses were not benefited. 

We recorded income tax expense for the six months ended June 30, 2013 of $3,330, which primarily consisted of foreign and state income taxes.

Our income tax benefit or expense is based on an annual effective tax rate forecast, including estimates and assumptions that could change during the year. The application of the requirements for accounting for income taxes in interim periods, after consideration of our valuation allowance, causes a significant variation in the typical relationship between income tax expense and pretax accounting income.

As of June 30, 2014, all of Century's U.S. and certain foreign deferred tax assets, net of deferred tax liabilities, continue to be subject to a valuation allowance. The realization of these assets is dependent on substantial future taxable income which, at June 30, 2014, is not more likely than not to be achieved.

Our Icelandic tax returns are subject to examination beginning with the 2008 tax year. Our 2010 through 2012 tax years are currently under review by the Directorate of Internal Revenue of Iceland.

Environmental Contingencies

Based upon all available information, we believe our current environmental liabilities do not have, and are not likely to have, a material adverse effect on our financial condition, results of operations or liquidity. Because of the issues and uncertainties described below and the inability to predict the requirements of future environmental laws, there can be no assurance that future capital expenditures and costs for environmental compliance at currently or formerly owned or operated properties will not result in liabilities that may have a material adverse effect on our financial condition, results of operations or liquidity.

It is our policy to accrue for costs associated with environmental assessments and remedial efforts when it becomes probable that a liability has been incurred and the costs can be reasonably estimated. The aggregate environmental-related accrued liabilities were $1,228 and $999 at June 30, 2014 and December 31, 2013, respectively. All accrued amounts have been recorded without giving effect to any possible future recoveries. With respect to costs for ongoing environmental compliance, including maintenance and monitoring, such costs are expensed as incurred.

Century Aluminum of West Virginia ("CAWV") continues to perform monitoring activities at our Ravenswood, West Virginia facility pursuant to an order issued by the United States Environmental Protection Agency (the "EPA") in 1994 (the "3008(h) Order").  In compliance with the 3008(h) Order, CAWV conducted a RCRA facility investigation ("RFI") evaluating other areas at Ravenswood that may have contamination requiring remediation. The RFI has been approved by appropriate agencies.  CAWV has completed interim remediation measures at two sites identified in the RFI, and we believe no further remediation will be required. A final order approving CAWV's Corrective Measures Study, which formally documents the conclusion of these activities, has been issued by the EPA. Under the order, CAWV's responsibilities going forward include monitoring specific wells as well as restricting access to certain parts of the site. 

Prior to our purchase of Hawesville, the EPA issued a final Record of Decision ("ROD") under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"). By agreement, Southwire Company ("Southwire"), the former owner and operator of Hawesville, is required to perform all obligations under the ROD.  CAKY has agreed to operate and maintain the ground water treatment system required under the ROD on behalf of Southwire, and Southwire will reimburse CAKY for any expense that exceeds $400 annually. The groundwater treatment system ceased operations in May 2010 and was decommissioned and removed from the site in 2012. Quarterly monitoring of specific wells is ongoing.

In July 2006, we were named as a defendant, together with certain affiliates of Alcan Inc., in a lawsuit brought by Alcoa Inc. seeking to determine responsibility for certain environmental indemnity obligations related to the sale of a cast aluminum plate manufacturing facility located in Vernon, California, which we purchased from Alcoa Inc. in December 1998, and sold to Alcan Rolled Products-Ravenswood LLC in July 1999. The complaint also seeks costs and attorney fees. The matter is in a preliminary stage in the U.S. District Court for the District of Delaware, and we cannot predict the ultimate outcome of this action or estimate a range of possible losses related to this matter at this time.

Matters relating to the St. Croix Alumina Refining Facility

We are a party to an EPA Administrative Order on Consent (the "Order") pursuant to which certain past and present owners of an alumina refining facility at St. Croix, Virgin Islands (the "St. Croix Alumina Refinery") have agreed to carry out a Hydrocarbon Recovery Plan to remove and manage hydrocarbons floating on groundwater underlying the facility.  Pursuant to the Hydrocarbon Recovery Plan, recovered hydrocarbons and groundwater are delivered to the adjacent petroleum refinery where they are received and managed. In connection with the sale of the facility by Lockheed Martin Corporation ("Lockheed") to one of our affiliates, Virgin Islands Alumina Corporation ("Vialco"), in 1989, Lockheed, Vialco and Century entered into the Lockheed-Vialco Asset Purchase Agreement. The indemnity provisions contained in the Lockheed-Vialco Asset Purchase Agreement allocate responsibility for certain environmental matters. Lockheed has tendered indemnity to Vialco. We have likewise tendered indemnity to Lockheed. Through June 30, 2014, we have expended approximately $1,033 on the Hydrocarbon Recovery Plan.  At this time, we are not able to estimate the amount of any future potential payments under this indemnification to comply with the Order, but we do not anticipate that any such amounts will have a material adverse effect on our financial condition, results of operations or liquidity, regardless of the final outcome. Vialco sold the St. Croix Alumina Refinery to St. Croix Alumina, LLC, a subsidiary of Alcoa in 1995.

In December 2010, Century was among several defendants named in a lawsuit filed by plaintiffs who either worked, resided or owned property in the area downwind from the St. Croix Alumina Refinery. In March 2011, Century was also named a defendant in a nearly identical suit brought by certain additional plaintiffs. The plaintiffs in both suits allege damages caused by the presence of red mud and other particulates coming from the alumina facility and are seeking unspecified monetary damages, costs and attorney fees as well as certain injunctive relief. We have tendered indemnity and defense to St. Croix Alumina LLC and Alcoa Alumina & Chemical LLC under the terms of an acquisition agreement relating to the facility and have filed motions to dismiss plaintiffs’ claims, but the Superior Court of the Virgin Islands, Division of St. Croix has not yet ruled on the motions. At this time, it is not practicable to predict the ultimate outcome of or to estimate a range of possible losses for any of the foregoing actions relating to the St. Croix Alumina Refinery.

In July 2014, we entered into a settlement (the "St. Croix Settlement") with the plantiffs in certain matters related to the St. Croix Alumina Refinery.

The first lawsuit (the "2005 Action") covered by the St. Croix Settlement was filed in May 2005 by the Commissioner of the Department of Planning and Natural Resources ("DPNR"), in his capacity as Trustee for Natural Resources of the United States Virgin Islands against Vialco and certain other named defendants.  The complaint alleged damages to natural resources caused by alleged releases from the St. Croix Alumina Refinery and the adjacent petroleum refinery.  The primary cause of action was pursuant to the natural resource damage provisions of CERCLA, but various ancillary Territorial law causes of action were included as well.  We and Lockheed each tendered indemnity and defense of the case to the other pursuant to the terms of the Lockheed-Vialco Asset Purchase Agreement.  The complaint sought unspecified monetary damages, costs and attorney fees. In November 2011, the District Court of the Virgin Islands, Division of St. Croix granted a motion by Century, dismissing Century from the case. Vialco, however, remained a defendant and asserted factual and affirmative defenses.  

The second lawsuit (the "Superior Court Action") covered by the St. Croix Settlement was filed in December 2006 by the Commissioner of the DPNR against Vialco and the succeeding owners of the St. Croix Alumina Refinery. The complaint alleged that the defendants failed to take certain actions specified in a Coastal Zone management permit issued to Vialco in October 1994, and alleged violations of territorial water pollution control laws during the various defendants’ periods of ownership. The complaint sought statutory and other unspecified monetary penalties for the alleged violations. On March 19, 2012, the plaintiff filed a motion to dismiss the settling defendants in the DPNR case described above from this action.  On May 9, 2012, the Superior Court of the Virgin Islands, Division of St. Croix granted plaintiff's motion to dismiss leaving Vialco as the only remaining defendant in this action. 

Finally, in May 2009, St. Croix Renaissance Group, L.L.L.P. ("SCRG") filed a third-party complaint (the "2009 Action") for contribution and other relief against several third-party defendants, including Century and Vialco, relating to a lawsuit filed against SCRG seeking recovery of response costs relating to the aforementioned DPNR CERCLA matter. In February 2011, the District Court of the Virgin Islands, Division of St. Croix granted a motion by Century, dismissing Century from the case. In March 2011, the court granted the remaining defendants’, including Vialco’s, motion for summary judgment, dismissing the case. The plaintiff filed a notice of appeal with the Third Circuit Court of Appeals in May 2011. On June 5, 2013, the Third Circuit Court of Appeals reversed the lower court's ruling, holding that plaintiff's expenditures of funds may be found as recoverable response costs incurred by the government entitling plaintiffs to recover future response costs. Vialco remained the only Century entity in the litigation.

Pursuant to the terms of the St. Croix Settlement, entered into as of July 7, 2014 by and among Vialco, DPNR, the Commissioner of the DPNR and the Government of the Virgin Islands (the “Government”), Vialco agreed to pay $625 to the Government in consideration of full release by DPNR, the Commissioner of the DPNR and the Government from all claims asserted in and relief, including attorneys’ fees and litigation costs ever sought or which could be sought by such plaintiffs in the 2005 Action, the Superior Court Action and the 2009 Action.

Legal Contingencies

In addition to the foregoing matters, we have pending against us or may be subject to various lawsuits, claims and proceedings related primarily to employment, commercial, stockholder, safety and health matters.

In evaluating whether to accrue for losses associated with legal contingencies, it is our policy to take into consideration factors such as the facts and circumstances asserted, our historical experience with contingencies of a similar nature, the likelihood of our prevailing and the severity of any potential loss.  For some matters, no accrual is established because we have assessed our risk of loss to be remote.  Where the risk of loss is probable and the amount of the loss can be reasonably estimated, we record an accrual, either on an individual basis or with respect to a group of matters involving similar claims, based on the factors set forth above.  

When we have assessed that a loss associated with legal contingencies is reasonably possible, we determine if estimates of possible losses or ranges of possible losses are in excess of related accrued liabilities, if any.  Based on current knowledge, management has ascertained estimates for losses that are reasonably possible and management does not believe that any reasonably possible outcomes in excess of our accruals, if any, either individually or in aggregate, would be material to our financial condition, results of operations, or liquidity. We reevaluate and update our assessments and accruals as matters progress over time.

In April 2013, our subsidiary Nordural Grundartangi ehf received a ruling in an arbitration case involving two of its power suppliers, HS Orka hf ("HS") and Orkuveita Reykjavikur ("OR"). Under the arbitration award, Nordural Grundartangi ehf is restricted from reducing power under its existing power contracts with HS and OR in order to take power under a separate power contract with OR originally intended to be used at Helguvik. Nordural Grundartangi ehf remains entitled to take power under the OR Helguvik contract to the extent that its power needs exceed the amount of power provided under its existing power contracts. As part of the award, the tribunal awarded HS damages and Nordural Grundartangi ehf paid $1,470 to HS in full satisfaction of such award. The tribunal ordered each party to pay its own legal fees and costs. While no damages were awarded to OR as part of the arbitration, OR subsequently alleged damages against Nordural Grundartangi ehf.  In June 2014, we reached a settlement with OR pursuant to the terms of which, among other things, Nordural Grundartangi ehf agreed to pay $3,600 to OR and OR withdrew and released each of Nordural Grundartangi ehf and Nordural Helguvik ehf from and against all claims related to the reduction in the power purchased under the existing power contracts. This settlement amount was paid in July 2014. As part of the settlement, Nordural Helguvik ehf and OR also entered into a Supplemental Power Contract pursuant to which OR agreed to provide supplemental power to Grundartangi or Helguvik from time to time during the remaining term of the existing Nordural Helguvik ehf power contract with OR.

Ravenswood Retiree Medical Benefits changes

In November 2009, CAWV filed a class action complaint for declaratory judgment against the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union ("USWA"), the USWA’s local and certain CAWV retirees, individually and as class representatives, seeking a declaration of CAWV’s rights to modify/terminate retiree medical benefits.  Later in November 2009, the USWA and representatives of a retiree class filed a separate suit against CAWV, Century Aluminum Company, Century Aluminum Master Welfare Benefit Plan, and various John Does with respect to the foregoing.  These actions, entitled Dewhurst, et al. v. Century Aluminum Co., et al., and Century Aluminum of West Virginia, Inc. v. United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union, AFL-CIO/CLC, et al., have been consolidated and venue has been set in the District Court for the Southern District of West Virginia. In January 2010, the USWA filed a motion for preliminary injunction to prevent us from implementing any modifications to the retiree medical benefits while these lawsuits are pending, which was dismissed by the trial court, and affirmed upon appeal. CAWV has filed a motion for summary judgment of these actions. The case in chief is currently proceeding in the trial court, subject to the court’s ruling on the motion for summary judgment.

PBGC Settlement

In June 2011, the Pension Benefit Guaranty Corporation (the "PBGC") informed us that it believed a "cessation of operations" under ERISA had occurred at our Ravenswood facility as a result of the curtailment of operations at the facility. Although we disagree that a "cessation of operations" occurred, we entered into a settlement agreement with the PBGC in April 2013 to resolve the matter. Pursuant to the terms of the agreement, we will make additional contributions (above any minimum required contributions) to our defined benefit pension plans totaling approximately $17,400 over the term of the agreement. During 2013, we made contributions pursuant to this agreement of approximately $6,700. Under certain circumstances, in periods of lower primary aluminum prices relative to our cost of 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 the first quarter of 2014, we elected to defer contributions for 2014 under the PBGC agreement and have provided the PBGC with the appropriate security.

Power Commitments

Hawesville

In August 2012, CAKY issued a 12-month notice to terminate its long-term power supply arrangement with Kenergy. Pursuant to the termination notice, the Hawesville Power Agreement terminated on August 20, 2013.  

Effective August 20, 2013, the Kentucky Public Service Commission ("KPSC") approved a power supply arrangement with Kenergy and 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 them. 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.

Sebree

 In January 2013, Sebree (then still owned by RTA) issued a 12-month notice to terminate its long-term power supply agreement (the "Sebree Power Agreement") with Kenergy. Pursuant to the termination notice, the Sebree Power Agreement terminated on January 31, 2014.

Effective February 1, 2014, the KPSC approved a new 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 them. 

Mt. Holly

Mt. Holly has a power purchase agreement (the "Santee Cooper Agreement") with the South Carolina Public Service Authority ("Santee Cooper") with a term through December 2015.  The Santee Cooper 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 Santee Cooper Agreement restricts Mt. Holly’s ability to reduce its power consumption (or the associated payment obligations) below contracted levels and to terminate the agreement, unless, in each case, the LME falls below certain negotiated levels.

In 2012, Mt. Holly and Santee Cooper amended the terms of the Santee Cooper Agreement in order to allow Mt. Holly to receive all or a portion of Mt. Holly's 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, among other factors, on the cost of natural gas rather than Santee Cooper's system average fuel costs, which are primarily coal-based. The amended power agreement provides that Mt. Holly may continue to receive its supplemental power requirements from the off-system facility through December 31, 2015.

On June 30, 2014, Mt. Holly gave notice to Santee Cooper under the Santee Cooper Agreement to reduce the contact 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. 

Ravenswood

CAWV has a power purchase agreement (the "APCo Agreement") with the Appalachian Power Company ("APCo").  CAWV currently purchases a limited amount of power under the APCo Agreement as necessary to maintain its Ravenswood smelter, which is presently curtailed.  Power is supplied under the APCo Agreement at prices set forth in published tariffs (which are subject to change), with certain adjustments.   

Grundartangi

Nordural Grundartangi ehf has power purchase agreements with HS, Landsvirkjun and OR to provide power to its Grundartangi smelter.  These power purchase agreements, which will expire on various dates from 2019 through 2036, provide power at LME-based variable rates.  Each power purchase agreement contains take-or-pay obligations with respect to a significant percentage of the total committed and available power under such agreement.

In the fourth quarter of 2011, an additional 47.5 MW of power became available under a power purchase agreement with OR. This power can be used at either Grundartangi or Helguvik and is currently being utilized at Grundartangi.

In June 2012, Nordural Grundartangi ehf entered into a 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 June 30, 2014, these power prepayments totaled approximately $2,000. We do not expect the amount of the prepayment to grow any higher, but we do not expect to realize the benefits from the prepayments in the near term.

Helguvik

Nordural Helguvik ehf has power purchase agreements with HS and OR to provide power to the Helguvik project.  These power purchase agreements provide power at LME-based variable rates and contain take-or-pay obligations with respect to a significant percentage of the total committed and available power under such agreements.  The first stage of power under the OR power purchase agreement (approximately 47.5 MW) became available in the fourth quarter of 2011 and is currently being utilized at Grundartangi. 

The power purchase agreements with HS and OR to provide power to Helguvik 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.  Nordural Helguvik ehf is in discussions with both HS and OR with respect to such conditions and other matters pertaining to these agreements. See Note 18 Subsequent events for additional information concerning these discussions.

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.

Other Commitments and Contingencies

Labor Commitments

Approximately 73% of our U.S. based work force is represented by the USWA. CAKY’s Hawesville employees represented by the USWA are under a collective bargaining agreement that expires on March 31, 2015. The Sebree employees represented by the USWA are under a collective bargaining agreement that expires on October 28, 2014. See Note 18 Subsequent events for additional information about Sebree's new collective bargaining agreement with the USWA that expires on October 28, 2019.

Approximately 82% of Grundartangi’s work force is represented by five labor unions, governed by a labor agreement that expires on December 31, 2014.

Approximately 77% of Vlissingen's work force is represented by the Federation for the Metal and Electrical Industry ("FME"), governed by a labor agreement that expires on May 1, 2015.

E.ON contingent obligation – net (1)	Other liabilities	—		—
TOTAL		$	—	$	140

(1) See Note 9 Debt for additional information about the E.ON contingent obligation.

Midwest premium contracts

We entered into a fixed-price forward contract that settled monthly from January 2014 to March 2014 based on the

Midwest premium price published in the Platts Metals Week for the applicable period. Losses associated with the settlements of the U.S. Midwest premium contracts were recorded in net gain (loss) on forward and derivative contracts on the consolidated

statement of operations.

Primary aluminum sales contract

We had a contract to sell to Glencore plc (together with its subsidiaries, "Glencore") primary aluminum produced at Mt. Holly, Hawesville and Sebree through December 31, 2013 (the "Glencore Metal Agreement"). The Glencore Metal Agreement was a physical delivery contract for primary aluminum with variable, LME-based pricing.  Under the Glencore Metal Agreement, pricing was based on market prices, adjusted by a negotiated U.S. Midwest premium with a cap and a floor as applied to the current U.S. Midwest premium.  We accounted for the Glencore Metal Agreement as a derivative instrument under ASC 815 "Derivatives and Hedging."  Gains and losses on the derivative were based on the difference between the contracted U.S. Midwest premium and actual and forecasted U.S. Midwest premiums.  Settlements were recorded in related party sales.  Unrealized gains (losses) based on forecasted U.S. Midwest premiums were recorded in net gain (loss) on forward and derivative contracts on the consolidated statements of operations.

Primary aluminum sales contract premium (tonnes) (1)	—	1,782
Midwest premium contracts (tonnes)	—	6,000

(1) Represents the remaining physical deliveries under the Glencore Metal Agreement.

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