CENTURY ALUMINUM COMPANY
Notes to the Consolidated Financial Statements for the
Three and six months ended June 30, 2013 and 2012
(Dollar amounts in thousands, except 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, 2012. 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 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013. Throughout this Form 10-Q, and unless expressly stated otherwise or as the context otherwise requires, "Century Aluminum," "Century," "we," "us," "our" and "ours" refer to Century Aluminum Company and its consolidated subsidiaries.

2. | Acquisition of Sebree aluminum smelter

Acquisition of Sebree 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 annual hot metal production capacity of 205,000 metric tons of primary aluminum and employs approximately 500 men and women. The purchase price for the acquisition was $61,000 (subject to customary working capital adjustments), of which we have paid $48,000 as of June 30, 2013. The remaining portion of the purchase price will be paid following final determination of the applicable working capital adjustments, which will be determined based on the amount of working capital transferred to Century Sebree at closing versus a target working capital amount of $71,000. As part of the transaction, RTA retained all historical environmental liabilities of the Sebree smelter and has agreed to fully fund the pension plan being assumed by Century.
Purchase Price Allocation
Allocating the purchase price to the acquired assets and liabilities involves management judgment. We allocate the purchase price to the assets acquired, liabilities assumed, and any bargain gain (or goodwill) in accordance with ASC 805, "Business Combinations." Once it has been determined that recognition of an asset or liability in a business combination is appropriate, we measure the asset or liability at fair value in accordance with the principles of ASC 820, "Fair Value Measurements and Disclosures." Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
The determination of the fair value of certain intangible assets and/or liabilities require significant management judgment in each of the following areas:

• | Identify the acquired intangible assets or liabilities. In the case of the Sebree acquisition, we assumed a power contract liability as the contract price is in excess of current market prices.

• | Estimate the fair value of the intangible assets and/or liabilities. We consider various approaches to value the acquired intangible assets and/or liabilities. These valuation approaches include the cost approach, which measures the value of an asset based on the cost to reproduce it or replace it with a like asset; the market approach, which values the assets through an analysis of sales and offerings of comparable assets; and the income approach, which measures the value of an asset (or liability) by measuring the present worth of the economic benefits (or costs) it is expected to produce.

8

CENTURY ALUMINUM COMPANY
Notes to the Consolidated Financial Statements (continued)
(Unaudited)
The allocation of the purchase price to the assets acquired and liabilities assumed is based on the estimated fair values at the date of acquisition. The purchase price allocation is preliminary and subject to change based on the finalization of the valuation of assets and liabilities. Based on the preliminary purchase price allocation, we recorded a gain on bargain purchase of approximately $2,042. The gain on bargain purchase reflects the current London Metal Exchange (the "LME") market and the market risk associated with the long term power supply for the facility. The following table summarizes the preliminary estimates of fair value of the assets acquired and the liabilities assumed as of the acquisition date:

Consideration: |
Cash (1) | $ | 47,373 |
Assets Acquired: |
Inventories | 58,496 |
Prepaid and other current assets | 363 |
Property, plant and equipment - net | 55,520 |
Total assets acquired | $ | 114,379 |
Liabilities Assumed: |
Accrued and other current liabilities | $ | 44,121 |
Accrued pension benefit costs | 5,039 |
Accrued post retirement benefit costs | 6,544 |
Other liabilities | 8,003 |
Deferred taxes | 1,257 |
Total liabilities assumed | $ | 64,964 |
Gain on bargain purchase: | $ | 2,042 |

(1) | This amount represents our preliminary estimate of consideration based on our expectation of the working capital adjustments.

Through June 30, 2013, the actual revenue and net loss of Sebree since the acquisition date of June 1, 2013 included in the consolidated statement of operations is as follows:

| From Acquisition date through
| June 30, 2013
Sebree revenue | $ | 38,753 |
Sebree net loss | (3,456 | )

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 or January 1, 2012. 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 or January 1, 2012, 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 | 2012 | 2013 | 2012
Pro forma revenues | $ | 413,907 |  | $ | 444,267 |  | $ | 861,605 |  | $ | 890,860 |

3. | Asset purchase

In June 2012, Century Vlissingen purchased substantially all of the assets of the Zalco anode production facility located in Vlissingen, the Netherlands for approximately $12,500. In connection with the purchase, we entered into a ground lease with respect to the facility that is renewable at our option. Century Vlissingen did not assume, and is indemnified by the seller against, historical liabilities of the facility.
The anode production facility, which was curtailed by Zalco in December 2011, will require a significant capital investment to modernize the facility, comply with environmental regulations and optimize anode production for our smelter in Grundartangi. We expect the first 75,000 metric tons of capacity will be restarted in late 2013 and will provide an anode supply to replace third-party anode supply contracts that will terminate in 2013.

4. | 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 Accounting Standards Codification Manual ("ASC") 820 "Fair Value Measurements."

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

(1) | Trust assets are currently invested in money market funds. 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 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 below.

5. | Derivative and hedging instruments

The following table provides the fair value and balance sheet classification of our derivatives:

Fair Value of Derivative Liabilities
| Balance sheet location | June 30, 2013 | December 31, 2012
DERIVATIVE LIABILITIES: |  |  |
Aluminum sales premium contracts – current portion | Accrued and other current liabilities | $ | 773 |  | $ | 1,170 |
E.ON contingent obligation - net (1) | Other liabilities | — |  | 15,369 |
TOTAL |  | $ | 773 |  | $ | 16,539 |

(1) | Based on the LME forward market prices for primary aluminum at June 30, 2013 and management's estimate of the LME forward market for periods beyond the quoted periods, 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. See Note 10 Debt for additional information about the E.ON contingent obligation fair value.

Primary aluminum put option contracts
In the past, we have entered into primary aluminum put option contracts that settled monthly based on LME prices. The option contract volumes accounted for a portion of our domestic production, with a strike price around our domestic facilities’ average cash basis break-even price at the time.
Our counterparties included two non-related third parties and an affiliate of Glencore Xstrata plc (together with its subsidiaries, "Glencore"), a related party. We paid cash premiums to enter into the put option contracts and recorded an asset on the consolidated balance sheets. We determined the fair value of the put option contracts using a Black-Scholes model with market data provided by an independent vendor. See the derivatives not designated as hedging instruments table below for more information.
Aluminum sales premium contracts
The Glencore Metal Agreement is a physical delivery contract for primary aluminum through December 31, 2013 with variable, LME-based pricing. Under the Glencore Metal Agreement, pricing is based on market prices, adjusted by a negotiated U.S. Midwest premium with a cap and a floor as applied to the current U.S. Midwest premium. We account for the Glencore Metal Agreement as a derivative instrument under ASC 815. Gains and losses on the derivative are based on the difference between the contracted U.S. Midwest premium and actual and forecasted U.S. Midwest premiums. Settlements are recorded in related party sales. Unrealized gains (losses) based on forecasted U.S. Midwest premiums are recorded in net gain (loss) on forward and derivative contracts on the consolidated statements of operations.

Primary aluminum sales contract premium (metric tons) (1) | 10,430 |  | 20,400 |

(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.
As of June 30, 2013, income of $153 is expected to be reclassified out of accumulated other comprehensive loss into earnings over the next 12-month period for derivative instruments that have been designated and have qualified as cash flow hedging instruments and for the related hedged transactions.

6. | Earnings per share

Basic earnings per share (“EPS”) amounts are calculated by dividing earnings available to common shareholders by the weighted average number of common shares outstanding. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive common shares outstanding. The following table shows the basic and diluted earnings per share for the three and six months ended June 30, 2013 and June 30, 2012:

| For the three months ended June 30,
| 2013 |  | 2012
| Loss | Shares (000) | Per-Share |  | Loss | Shares (000) | Per-Share
Net loss | $ | (34,573 | ) |  |  |  | $ | (12,277 | ) |  |
Amount allocated to common shareholders (1) | 100 | % |  |  |  | 100 | % |  |
Basic EPS: |  |  |  |  |  |  |
Loss allocable to common shareholders | (34,573 | ) | 88,597 |  | $ | (0.39 | ) |  | (12,277 | ) | 88,452 |  | $ | (0.14 | )
Diluted EPS: |  |  |  |  |  |  |

| 2013 |  | 2012
| Loss | Shares (000) | Per-Share |  | Loss | Shares (000) | Per-Share
Net loss | $ | (26,320 | ) |  |  |  | $ | (16,678 | ) |  |
Amount allocated to common shareholders (1) | 100 | % |  |  |  | 100 | % |  |
Basic EPS: |  |  |  |  |  |  |
Loss allocable to common shareholders | (26,320 | ) | 88,576 |  | $ | (0.30 | ) |  | (16,678 | ) | 88,589 |  | $ | (0.19 | )

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

Impact of our outstanding Series A Convertible Preferred Stock on EPS
Our Series A Convertible preferred stock has similar characteristics of a “participating security” as described by the ASC 260-10-45. In accordance with the guidance in the ASC 260-10-45, we calculated basic EPS using the Two-Class Method, allocating undistributed income to our preferred shareholder consistent with their participation rights, and diluted EPS using the If-Converted Method when applicable.
ASC 260-10-50 does not require the presentation of basic and diluted EPS for securities other than common stock and the EPS amounts, as presented, only pertain to our common stock.
The Two-Class Method is an earnings allocation formula that determines earnings per share for common shares and participating securities according to dividends declared (or accumulated) and the participation rights in undistributed earnings.
15

CENTURY ALUMINUM COMPANY
Notes to the Consolidated Financial Statements (continued)
(Unaudited)
The holders of our convertible preferred stock do not have a contractual obligation to share in the losses of Century. Thus, in periods where we report net losses, we will not allocate the net losses to the convertible preferred stock for the computation of basic or diluted EPS.

Calculation of EPS: | Three months ended June 30, | Six months ended June 30,
| 2013 | 2012 | 2013 | 2012
Options to purchase common stock | 620,334 |  | 626,334 |  | 620,334 |  | 626,334 |
Weighted average service-based share awards outstanding | 576,510 |  | 395,791 |  | 496,234 |  | 370,658 |
Excluded from the calculation of diluted EPS: |  |  |  |
Stock options (1) | 620,334 |  | 626,334 |  | 620,334 |  | 632,334 |
Service-based share award | 576,510 |  | 395,791 |  | 496,234 |  | 370,658 |

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

In March 2012, we repurchased 400,000 shares of our common stock under a stock repurchase program. See Note 7 Shareholders’ equity for additional information about this program. Shares repurchased under the program are excluded from the calculation of weighted average shares of common stock outstanding.
Service-based share awards for which vesting is based upon continued service are not considered issued and outstanding shares of common stock until vested and issued. However, the service-based share awards are considered common stock equivalents and, therefore, the weighted average service-based share awards are included, using the treasury stock method, in common shares outstanding for diluted earnings per share computations if they have a dilutive effect on earnings per share.

7. | Shareholders’ equity

Common Stock
Under our Restated Certificate of Incorporation, our Board of Directors is authorized to issue up to 195,000,000 shares of 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 $60,000 stock repurchase program. Under the program, we may repurchase up to $60,000 of our outstanding shares of common stock from time to time on the open market at prevailing market prices, in block trades or otherwise. The timing and amount of any shares repurchased 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.

CENTURY ALUMINUM COMPANY
Notes to the Consolidated Financial Statements (continued)
(Unaudited)
From August 11, 2011 through June 30, 2013, we repurchased 4,786,521 shares of common stock for an aggregate purchase price of $49,924. We had approximately $10,076 remaining under the repurchase program authorization as of June 30, 2013.
Series A Convertible Preferred Stock conversions
All shares of Series A Convertible Preferred Stock are held by Glencore. 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. See Common and Preferred Stock Activity table below for additional information about preferred stock conversions during the period.

Common and Preferred Stock Activity: | Preferred stock | Common stock
| Series A convertible | Treasury | Outstanding
Beginning balance as of December 31, 2012 | 80,283 |  | 4,786,521 |  | 88,548,637 |

Ending balance as of June 30, 2013 | 80,084 |  | 4,786,521 |  | 88,602,709 |

8. | Income taxes

We recorded income tax expense from continuing operations for the six months ended June 30, 2013 of $5,308 which primarily consist 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 from continuing operations for the six months ended June 30, 2012 of $6,216 which primarily consist of foreign and state income taxes.
Income tax expense is based on an annual effective tax rate forecast, including estimates and assumptions that could change during the year.
As of June 30, 2013, 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, 2013, is not likely to be achieved.
During the six months ended June 30, 2013, we received notice from the Internal Revenue Service ("IRS") that the Congressional Joint Committee on Taxation finalized their review of the US Federal examinations for the income tax years 2008, 2009, and 2010 and refund years of 2004, 2005, 2006, and 2007 without exception to the conclusions reached by the IRS. This Joint Committee is a special nonpartisan Congressional committee involved with the analysis and drafting of federal tax legislation and as part of its mandate, reviews all federal tax refund claims over a certain amount. As a result of this determination, we have reduced the reserve for the unrecognized tax benefits related to prior years by $14,300. The reduction did not result in an impact to the effective tax rate since the reduction was offset by an increase in our valuation allowance. During the second quarter, we received refunds from the IRS of $5,009 following the Joint Committee review.
During the second quarter of 2013, we received notice from the Directorate of Internal Revenue of Iceland of their intent to conduct a periodic review regarding certain of our Icelandic subsidiaries for the years 2010-2012.

8.0% senior secured notes payable due May 15, 2014, net of debt discount of $1,626, interest payable semiannually | — |  | 247,979 |
7.5% senior unsecured notes payable due August 15, 2014, interest payable semiannually | 2,603 |  | 2,603 |
E.ON contingent obligation, principal and accrued interest, contingently payable monthly, annual interest rate of 10.94% (2) | — |  | 15,369 |
TOTAL | $ | 256,776 |  | $ | 273,766 |

(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, 2013 was 0.26%.

(2) | E.ON contingent obligation principal and interest payments are payable based on CAKY’s operating level and the LME price for primary aluminum. See E.ON contingent obligation below and Note 4 Fair value measurements for additional information.

Amended 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 and BNP Paribas, as lenders, entered into the Amended and Restated Loan and Security Agreement (the “New Credit Facility”), dated May 24, 2013, as amended, modifying the credit facility signed July 1, 2010. The New Credit Facility extended the term through May 24, 2018 and provides for borrowings of up to $137,500 in the aggregate, including up to $80,000 under a letter of credit sub-facility. Any letters of credit issued and outstanding under the New Credit Facility reduce our borrowing availability on a dollar-for-dollar basis.

CENTURY ALUMINUM COMPANY
Notes to the Consolidated Financial Statements (continued)

Status of our Credit Facility:

| June 30, 2013
New Credit Facility amount | $ | 137,500 |
Borrowing availability, net of outstanding letters of credit | 63,955 |
Outstanding borrowings on Credit Facility | — |
Letter of credit sub-facility amount | 80,000 |
Outstanding letters of credit issued under the Credit Facility | 73,545 |

Borrowing Base. The availability of funds under the New 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 New 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 New Credit Facility on a joint and several basis.
Interest Rates and Fees. Any amounts outstanding under the New 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 of such letters of credit that varies depending on whether the letter of credit exposure is cash collateralized.
Maturity. The New Credit Facility will mature on May 24, 2018.
Prepayments. We can make prepayments of amounts outstanding under the New Credit Facility, in whole or in part without premium or penalty, subject to standard LIBOR breakage costs, if applicable. We may be required to apply the proceeds from sales of collateral accounts, other than sales of inventory in the ordinary course of business, to repay amounts outstanding under the revolving credit facility and correspondingly reduce the commitments there under.
Covenants. The New Credit Facility contains customary covenants, including restrictions on mergers and acquisitions, indebtedness, affiliate transactions, liens, dividends and distributions, dispositions of collateral, investments and prepayments of indebtedness, as well as a covenant that requires the Borrowers to maintain certain minimum liquidity or availability requirements.
Events of Default. The New Credit Facility also includes customary events of default, including nonpayment, misrepresentation, breach of covenant, bankruptcy, change of ownership, certain judgments and certain cross defaults. Upon the occurrence of an event of default, commitments under the New Credit Facility may be terminated and amounts outstanding may be accelerated and declared immediately due and payable.
8% Notes Tender Offer, Consent Solicitation and Redemption
In May 2013, we commenced a tender offer and consent solicitation to the holders of the outstanding 8% Senior Secured Notes due 2014 (the “8.0% Notes Tender Offer”). Investors electing to participate in the 8.0% Notes Tender Offer consented to certain amendments and modifications to the indenture governing the 8.0% Notes to remove, among other things, most of the restrictive covenants, in exchange for which we paid these investors consent fees.
We received tenders and consents from holders of approximately 92% of the outstanding principal amount of the 8.0% Notes. The remaining 8.0% Notes outstanding that had not participated in the Tender Offer were redeemed at a redemption price of 100% of the principal amount thereof, plus accrued and unpaid interest (the “Redemption”). Together the 8.0% Tender
19

CENTURY ALUMINUM COMPANY
Notes to the Consolidated Financial Statements (continued)
(Unaudited)
Offer and Redemption satisfied and discharged our obligations under the 8.0% Notes and the related indenture. We used the net proceeds from the issuance of the 7.5% Senior Secured Notes due 2021 (the “7.5% Notes”) and available cash on hand to fund the 8.0% Notes Tender Offer and the Redemption.
In accordance with ASC 470, based on an evaluation of the characteristics of the 8.0% Notes and the 7.5% Notes that were recently issued, we determined the tender and redemption of the 8.0% Notes should be treated as an extinguishment of the debt and accordingly, we recorded a loss on early extinguishment of debt in the second quarter of 2013. The loss on early extinguishment of debt consisted of the write-off of deferred financing costs and the debt discount associated with the 8.0% Notes, as well as the tender premium paid as part of the 8.0% Notes Tender.
7.5% Notes
General. On June 4, 2013, we issued $250,000 of our 7.5% Notes in a private offering exempt from the registration requirements of the Securities Act. The 7.5% Notes were issued at a discount and we received gross 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 1st and December 1st of each year.
Maturity. The 7.5% Notes mature on June 1, 2021.
Seniority. The 7.5% Notes are senior secured obligations of Century, ranking equally in right of payment with all existing and future senior indebtedness of Century, but effectively senior to unsecured debt to the extent of the value of the collateral.
Guaranty. Our obligations under the 7.5% Notes are guaranteed by all of our existing and future domestic restricted subsidiaries (the “Guarantors”), except for foreign owned holding companies and any domestic restricted subsidiary that owns no assets other than equity interests or other investments in foreign subsidiaries, which guaranty shall in each case be a senior secured obligation of such Guarantors, ranking equally in right of payment with all existing and future senior indebtedness of such Guarantor but effectively senior to unsecured debt.
Collateral. Our obligations under the 7.5% Notes and the guarantors' obligations under the guarantees are secured by a pledge of and lien on (subject to certain exceptions):

(i) | all of our and the guarantors' plant, property and equipment (other than certain excluded property, such as the assets of Berkeley Aluminum, Inc., the owner of our interest in our Mt. Holly facility);

(i) | all equity interests in domestic subsidiaries directly owned by us and the guarantors and 65% of equity interests in foreign subsidiaries or foreign holding companies directly owned by us and the guarantors;

(ii) | intercompany notes owed by any non-guarantor to us or any guarantor to us; and

(iii) | proceeds of the foregoing.

Under certain circumstances, we may incur additional debt that also may be secured by liens on the collateral that are equal to or have priority over the liens securing the 7.5% Notes.
Redemption Rights. Prior to June 1, 2016, we may redeem the 7.5% Notes, in whole or in part, at a redemption price equal to 100% of the principal amount plus a make-whole premium, and if redeemed during the twelve-month period beginning on June 1 of the years indicated below, at the following redemption prices plus accrued and unpaid interest:

Year | Percentage
2016 | 105.625%
2017 | 103.750%
2018 | 101.875%
2019 and thereafter | 100.000%

Upon a change of control (as defined in the indenture governing the 7.5% Notes), we will be required to make an offer to purchase the 7.5% Notes at a purchase price equal to 101% of the outstanding principal amount of the 7.5% Notes on the date of the purchase, plus accrued interest to the date of purchase.
Covenants. The indenture governing the 7.5% Notes contains customary covenants which may limit our ability, and the ability of certain of our subsidiaries, to: (i) incur additional debt; (ii) create liens; (iii) pay dividends or make distributions in respect of capital stock; (iv) purchase or redeem capital stock; (v) make investments or certain other restricted payments; (vi) sell assets; (vii) issue or sell stock of certain subsidiaries; (viii) enter into transactions with shareholders or affiliates; and (ix) effect a consolidation or merger.
E.ON contingent obligation
The E.ON contingent obligation consists of the aggregate E.ON payments under the Big Rivers Agreement to Big Rivers on CAKY’s behalf in excess of the agreed upon base amount. Our obligation to make repayments is contingent upon certain operating criteria for our Hawesville, Kentucky facility and the LME price of primary aluminum. When the conditions for repayment are met, and for so long so those conditions continue to be met, we will be obligated to make principal and interest payments, in up to 72 monthly payments.
Based on the LME forward market prices for primary aluminum at June 30, 2013 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 $16,075 in net gain (loss) on forward and derivative contracts for the six months ended June 30, 2013. Based on the LME forward market prices for primary aluminum at June 30, 2013 and management's estimate of the LME forward market for periods beyond the quoted periods, 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:

11. | Commitments and contingencies

Environmental Contingencies
Based upon all available information, we believe our current environmental liabilities do not have, and are not likely to have, a material adverse effect on our financial condition, results of operations or liquidity. Because of the issues and uncertainties described below and the inability to predict the requirements of future environmental laws, there can be no assurance that future capital expenditures and costs for environmental compliance at currently or formerly owned or operated properties will not result in liabilities which may have a material adverse effect.
It is our policy to accrue for costs associated with environmental assessments and remedial efforts when it becomes probable that a liability has been incurred and the costs can be reasonably estimated. The aggregate environmental-related accrued liabilities were $1,396 and $906 at June 30, 2013 and December 31, 2012, 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 remedial measures at our Ravenswood West Virginia facility pursuant to an order issued by the EPA in 1994 (the “3008(h) Order”). CAWV also conducted a RCRA facility investigation (“RFI”) under the 3008(h) Order evaluating other areas at Ravenswood that may have contamination requiring remediation. The RFI has been approved by appropriate agencies. CAWV has completed interim remediation measures at two sites identified in the RFI, and we believe no further remediation will be required. A Corrective Measures Study, which formally documents the conclusion of these activities, has been submitted by the EPA and a final order has been completed and signed by the EPA in April 2013. 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 is to perform all obligations under the ROD. CAKY has agreed to operate and maintain the ground water treatment system required under the ROD on behalf of Southwire, and Southwire will reimburse CAKY for any expense that exceeds $400 annually.
In July 2006, we were named as a defendant, together with certain affiliates of Alcan Inc., in a lawsuit brought by Alcoa Inc. seeking to determine responsibility for certain environmental indemnity obligations related to the sale of a cast aluminum plate manufacturing facility located in Vernon, California, which we purchased from Alcoa Inc. in December 1998, and sold to Alcan Rolled Products-Ravenswood LLC in July 1999. The complaint also seeks costs and attorney fees. The matter is in a preliminary stage, and we cannot predict the ultimate outcome of this action or estimate a range of possible losses related to this matter at this time. We do not expect that the ultimate costs to resolve this action will have a material adverse effect on our financial condition, results of operations or liquidity, regardless of the final outcome.
Matters relating to the St. Croix Alumina Refining Facility
We are a party to an EPA Administrative Order on Consent (the “Order”) pursuant to which other past and present owners of an alumina refining facility at St. Croix, Virgin Islands (the “St. Croix Alumina Refinery”) have agreed to carry out a Hydrocarbon Recovery Plan to remove and manage hydrocarbons floating on groundwater underlying the facility. Pursuant to the Hydrocarbon Recovery Plan, recovered hydrocarbons and groundwater are delivered to the adjacent petroleum refinery where they are received and managed. In connection with the sale of the facility by Lockheed Martin Corporation (“Lockheed”) to one of our affiliates, Virgin Islands Alumina Corporation (“Vialco”), in 1989, Lockheed, Vialco and Century entered into the Lockheed-Vialco Asset Purchase Agreement. The indemnity provisions contained in the Lockheed-Vialco Asset Purchase Agreement allocate responsibility for certain environmental matters. Lockheed has tendered indemnity and defense of the above matter to Vialco. We have likewise tendered indemnity to Lockheed. Through June 30, 2013, we have expended approximately $985 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.
In May 2005, we and Vialco were among several defendants listed in a lawsuit filed by the Commissioner of the Department of Planning and Natural Resources (“DPNR”), in his capacity as Trustee for Natural Resources of the United States Virgin Islands. The complaint alleges damages to natural resources caused by alleged releases from the St. Croix Alumina Refinery and the adjacent petroleum refinery. The primary cause of action is pursuant to the natural resource damage provisions of CERCLA, but various ancillary Territorial law causes of action were included as well. We and Lockheed have each tendered indemnity and defense of the case to the other pursuant to the terms of the Lockheed-Vialco Asset Purchase Agreement. The complaint seeks unspecified monetary damages, costs and attorney fees. In November 2011, the court granted a motion by Century, dismissing Century from the case. Vialco, however, remains a defendant in this case and has asserted factual and affirmative defenses. The parties are currently engaged in the discovery process. As of June 30, 2013, no trial date has been set for the remaining claims.
In December 2006, Vialco and the two succeeding owners of the St. Croix Alumina Refinery were named as defendants in a lawsuit filed by the Commissioner of the DPNR. The complaint alleges the defendants failed to take certain actions specified in a Coastal Zone management permit issued to Vialco in October 1994, and alleges violations of territorial water pollution control laws during the various defendants’ periods of ownership. The complaint seeks statutory and other unspecified monetary penalties for the alleged violations. The parties are currently engaged in the discovery process.

In May 2009, St. Croix Renaissance Group, L.L.L.P. (“SCRG”) filed a third-party complaint for contribution and other relief against several third-party defendants, including Vialco, relating to a lawsuit filed against SCRG seeking recovery of response costs relating to the aforementioned DPNR CERCLA matter. In February 2011, the court granted a motion by Century, dismissing Century from the case. Vialco, however, remains a defendant in this case. In March 2011, the court granted the remaining defendants’, including Vialco’s, motion for summary judgment, dismissing the case. The plaintiff filed a notice of appeal with the Third Circuit Court of Appeals in May 2011. On June 5, 2013, the Third Circuit Court of Appeals reversed the lower court's ruling to hold that plaintiff's expenditures of funds may be found as recoverable response costs incurred by the government entitling plaintiffs to recover future response costs, but did not rule. Vialco remains the only Century entity in the litigation. At this time, it is not practicable to predict the ultimate outcome of or to estimate a range of possible losses relating to any of the foregoing.
In December 2010, Century was among several defendants listed in a lawsuit filed by approximately 2,300 plaintiffs who either worked, resided or owned property in the area downwind from the St. Croix Alumina Refinery. In March 2011, Century was also named a defendant in a nearly identical suit brought by approximately 200 plaintiffs previously named in the aforementioned suit. The plaintiffs in both suits allege damages caused by the presence of red mud and other particulates coming from the alumina facility 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 a motion to dismiss plaintiffs’ claims, but the court has not yet ruled on the motion.
Pursuant to the terms of the asset purchase agreement between Vialco and the purchaser of the St. Croix Alumina Refinery in 1995, the purchaser assumed responsibility for all costs and other liabilities associated with the bauxite waste disposal facilities, including pre-closure and post-closure liabilities. At this time, it is not practicable to predict the ultimate outcome of or to estimate a range of possible losses relating to any of the foregoing actions.
Legal Contingencies
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, environmental, shareholder, 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.
We also determine estimates of reasonably possible losses or ranges of reasonably possible losses in excess of related accrued liabilities, if any, when we have assessed that a loss is reasonably possible. Based on current knowledge, management has ascertained estimates for losses that are reasonably possible and management does not believe that any reasonably possible outcomes in excess of our accruals, if any, 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.
We have been named as a defendant in a lawsuit filed by our former Chief Executive Officer, Logan Kruger, alleging breach of contract. The lawsuit alleges that Century anticipatorily breached the employment and severance protection agreements between Century and Mr. Kruger and that Century is obligated to make various severance payments in excess of $20,000 to Mr. Kruger under such agreements. In addition, the complaint seeks unspecified damages, including costs and attorneys’ fees. The trial court has transferred the matter to an arbitration panel for resolution. We believe these claims are without merit and intend to defend ourselves against them. The arbitration hearing is scheduled for the third quarter of 2013.

In March 2011, the purported stockholder class actions pending against us consolidated as In re: Century Aluminum Company Securities Litigation were dismissed with prejudice by the United States District Court for the Northern District of California. The plaintiffs in the class actions allege that we improperly accounted for cash flows associated with the termination of certain forward financial sales contracts which accounting allegedly resulted in artificial inflation of our stock price and investor losses. Plaintiffs are seeking rescission of our February 2009 common stock offering, unspecified compensatory damages, including interest thereon, costs and expenses and attorneys’ fees. In March 2011, plaintiffs filed a notice of appeal to the order and judgment entered by the trial court. In January 2013, the U.S. Court of Appeals for the Ninth Circuit (the "Ninth Circuit") affirmed the trial court's decision. Plaintiffs filed a motion for rehearing or hearing en banc, which the Ninth Circuit denied in April 2013.
In February 2010, our subsidiary, CAWV, was named as a defendant in a lawsuit filed by Ingram Barge Company ("Ingram") in the United States District Court for the Middle District of Tennessee. The lawsuit alleges that CAWV breached two barging contracts with Ingram by failing to consume a specified amount of barging services as a result of the curtailment of operations at Ravenswood. In May 2013, the parties entered into a settlement agreement pursuant to which CAWV agreed to pay Ingram $1,575 and made certain commitments to Ingram with respect to future contracts.
In April 2013, our subsidiary Nordural Grundartangi, received a ruling in an arbitration case involving two of its power suppliers, HS Orka and Orkuveita Reykjavikur. Under the arbitration award, Nordural Grundartangi is restricted from reducing power under its existing power contracts with HS Orka and Orkuveita Reykjavikur in order to take power under a separate power contract with Orkuveita Reykjavikur originally intended to be used at Helguvik. Nordural Grundartangi remains entitled to take power under the Orkuveita Reykjavikur 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 Orka damages and Nordural Grundartangi paid $1,470 to HS Orka in full satisfaction of such award. The tribunal ordered each party to pay its own legal fees and costs. Orkuveita Reykjavikur has subsequently brought a claim for damages against Nordural Grundartangi based on the arbitration ruling. Nordural Grundartangi believes these claims are without merit and intends to defend itself against them.
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 union, and four 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 & Service Workers International Union, AFL-CIO/CLC, et al., have been consolidated and venue has been set in the District Court for the Southern District of West Virginia.
In January 2010, the USWA filed a motion for preliminary injunction to prevent us from implementing the foregoing changes while these lawsuits are pending, which was dismissed by the trial court. In August 2011, the Fourth Circuit Court of Appeals upheld the District Court’s dismissal of the USWA’s motion for preliminary injunction. The case is currently in the discovery stage.
Ravenswood Pension Plans
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, CAWV entered into a settlement agreement with the PBGC in April 2013 to resolve the matter. Pursuant to the terms of the agreement, CAWV will make additional contributions (above any minimum required contributions) to its defined benefit pension plans totaling approximately $17,400 over the term of the agreement, which runs through 2016. In April 2013, CAWV made the first scheduled contribution pursuant to this agreement of $5,900.

Power Commitments
Hawesville
In August 2012, CAKY issued a 12-month notice to terminate its long-term power supply agreement (the “Hawesville Power Agreement”) with Kenergy, a member cooperative of Big Rivers Electric Corporation (“Big Rivers”). The Hawesville Power Agreement is take-or-pay for Hawesville’s energy requirements at full production. During the 12-month notice period, Century is required to pay a demand charge for power, but is not obligated to continue operating the plant. The Hawesville Power Agreement currently provides sufficient power at cost-based rates for Hawesville’s full production capacity requirements, but, pursuant to the termination notice, the Hawesville Power Agreement will terminate on August 20, 2013. If a new power arrangement is not reached prior to August 20, 2013, the Hawesville plant will have to be curtailed.
On April 29, 2013, CAKY announced that it had reached a tentative agreement with Kenergy and Big Rivers on the framework for providing market priced power to the Hawesville smelter. Under the arrangement, the power companies would purchase power on the open market and pass it through to Hawesville at the market price plus additional costs incurred by them. Definitive agreements for the framework have been agreed to by the parties but must still be approved by various third parties, including the Kentucky Public Service Commission (“KPSC”). The definitive agreements have been submitted for approval to the KPSC, which is expected to issue a decision prior to the August 20, 2013 termination of the existing Hawesville Power Agreement.
Sebree
In January 2013, Sebree issued a 12-month notice to terminate its long-term power supply agreement (the “Sebree Power Agreement”) with Kenergy, a member cooperative of Big Rivers. The Sebree Power Agreement is take-or-pay for Sebree’s energy requirements at full production. During the 12-month notice period, Century is required to pay a demand charge for power, but is not obligated to continue operating the plant. The Sebree Power Agreement currently provides sufficient power at cost-based rates for Sebree’s full production capacity requirements, but, pursuant to the termination notice, the Sebree Power Agreement will terminate on January 31, 2014. If a new power arrangement is not reached prior to January 31, 2014, the Sebree plant will have to be curtailed.
We intend to seek a market-based power contract for Sebr ee similar to the tentative agreement we have reached for Hawesville, but n o assurance can be given that we will be able to obtain one.
Mt. Holly
Mt. Holly has a power purchase agreement (the “Santee Cooper Agreement”) with the South Carolina Public Service Authority (“Santee Cooper”) with a term through December 2015, unless extended. The Santee Cooper Agreement provides adequate power for Mt. Holly’s full production capacity requirements at prices fixed based on published rate schedules (which are subject to change), with adjustments for fuel prices and other items. The Santee Cooper Agreement restricts Mt. Holly’s ability to reduce its power consumption (or the associated payment obligations) below contracted levels and to terminate the agreement, unless, in each case, the LME falls below certain negotiated levels.
In 2012, Mt. Holly and Santee Cooper amended the terms of 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 on the cost of natural gas rather than Santee Cooper's system average fuel costs, which are primarily coal-based. The amendments to the power agreement may provide a benefit to Mt. Holly provided that natural gas costs remain below Santee Cooper's system average fuel costs. 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.

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 Orka hf (“HS”), Landsvirkjun and Orkuveita Reykjavikur (“OR”) to provide power to its Grundartangi smelter. These power purchase agreements, which will expire on various dates from 2019 through 2036, provide power at LME-based variable rates. Each power purchase agreement contains take-or-pay obligations with respect to a significant percentage of the total committed and available power under such agreement.
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 a portion is currently being utilized at Grundartangi.
In June 2012, Nordural Grundartangi entered into a new supplemental power contract with Landsvirkjun. The supplemental power contract, which will expire in October 2029 (or upon the occurrence of certain earlier events), will provide Nordural Grundartangi with supplemental power, as Nordural Grundartangi may request from time to time, at LME-based variable rates. Nordural Grundartangi has agreed to make certain prepayments to Landsvirkjun in connection with the contract, which will reduce the price paid for power at the time of consumption.
Helguvik
Nordural Helguvik 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 a portion of that power is currently being utilized at Grundartangi. No other power is currently available under either power purchase agreement. HS (with respect to all phases) and OR (with respect to all phases other than the first phase) have alleged that certain conditions to the delivery of power under the power purchase agreements have not been satisfied. Nordural Helguvik is in discussion with both HS and OR with respect to such conditions.
Other Commitments and Contingencies
Labor Commitments
Approximately 75% of our U.S. based work force is represented by the USWA. CAKY’s Hawesville plant employees represented by the USWA are under a collective bargaining agreement which expires on March 31, 2015. The Sebree plant employees represented by the USWA are under a collective bargaining agreement that expires on September 30, 2014.
In April 2010, Nordural Grundartangi ehf entered into a new labor agreement with the five labor unions representing approximately 84% of Grundartangi’s work force. The labor agreement expires on December 31, 2014.
The labor agreement for CAWV’s Ravenswood plant employees represented by the USWA expired on August 31, 2010.

Other Commitments
The Patient Protection and Affordable Care Act and the related Health Care and Education Reconciliation Act were enacted in March 2010. The Health Care Acts extend health care coverage to many uninsured individuals and expands coverage to those already insured. The Health Care Acts contain provisions which could impact our retiree medical benefits in future periods. However, the extent of that impact, if any, cannot be determined until regulations are promulgated under the Health Care Acts and additional interpretations of the Health Care Acts become available. We are continuing to assess the potential impacts that this legislation may have on our future results of operations, cash flows and financial position related to our health care benefits and other postretirement benefit obligations. Among other things, the Health Care Acts eliminated the tax deductibility of the Medicare Part D subsidy for companies that provide qualifying prescription drug coverage to retirees effective for years beginning after December 31, 2012.

12. | Forward delivery contracts and financial instruments

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.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Recent Developments
Century acquires the Sebree smelter
On June 1, 2013, our wholly owned subsidiary, Century Aluminum Sebree LLC ("Century Sebree") acquired the Sebree aluminum smelter from a subsidiary of Rio Tinto Alcan, Inc ("RTA"). Sebree, located in Robards, Kentucky, USA has an annual hot metal production capacity of 205,000 metric tons of primary aluminum and employs approximately 500 men and women.
The purchase price for the acquisition was $61 million (subject to customary working capital adjustments), of which we have paid $48 million as of June 30, 2013. The remaining portion of the purchase price will be paid following final determination of the applicable working capital adjustments, which will be determined based on the amount of working capital transferred to Century Sebree at closing versus a target working capital amount of $71 million. As part of the transaction, RTA retained all historical environmental liabilities of the Sebree smelter and has agreed to fully fund the pension plan assumed by Century at closing. See Part II Item 1A - Risk Factors for a discussion of risks related to the Sebree acquisition.
Revolving Credit Facility Amended
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 and BNP Paribas, as lenders, entered into the Amended and Restated Loan and Security Agreement (the “New Credit Facility”), dated May 24, 2013, as amended, modifying the credit facility signed July 1, 2010. The New Credit Facility extended the term through May 24, 2018 and provides for borrowings of up to $137.5 million in the aggregate, including up to $80 million under a letter of credit sub-facility. Any letters of credit issued and outstanding under the New Credit Facility reduce our borrowing availability on a dollar-for-dollar basis.
Century issues $250 million of 7.5% senior secured notes
On June 4, 2013, we issued $250 million 7.5% senior secured notes due 2021. The notes have an interest rate of 7.5% per annum and were issued at a price equal to 98.532% of their face value. Century used the net proceeds from the sale of the notes and available cash on hand for the tender offer and redemption of our outstanding 8% Senior Secured Notes due 2014.
Tender offer and redemption of 8.0% senior secured notes due 2014
On May 20, 2013, we commenced a cash tender offer for any and all of our 8% Senior Secured Notes due 2014 (the "2014 Notes"). In conjunction with the tender offer, we solicited consents to eliminate most of the covenants, certain events of default and certain other provisions contained in the indenture for the 2014 Notes. 2014 Notes validly tendered prior to June 4, 2013 received $1,003.75 for each $1,000 principal amount.
We received tenders and consents from holders of approximately 92.18% of the principal amount of the 2014 Notes in the tender offer.
On June 4, 2013, we elected to redeem the remaining outstanding 2014 Notes at par, plus accrued and unpaid interest and transferred the necessary funds to our trustee to complete the redemption.
We used the net proceeds from the issuance of the 7.5% senior secured notes due 2021 and available cash on hand to fund the tender offer and redemption of our 2014 Notes.

Tentative agreement on framework for market priced power for Hawesville
On April 29, 2013, Century Aluminum of Kentucky ("CAKY") announced that it reached a tentative agreement on the framework for providing market priced power to the Hawesville smelter. Under the arrangement, the power companies would purchase power on the open market and pass it through to Hawesville at the market price plus additional costs incurred by them. Definitive agreements for the framework have been agreed to by the parties but must still be approved by various third parties, including the Kentucky Public Service Commission ("KPSC"). The definitive agreements have been submitted for approval to the KPSC. The parties intend to move as expeditiously as possible to finalize the agreement in advance of the expiration of the current power contract on August 20, 2013. See Part II Item 1A - Risk Factors for a discussion of risks related to the Hawesville tentative power agreement.
Conditional WARN Notice and notice to terminate Southwire Metal Agreement at Hawesville
On April 16, 2013, CAKY gave notice to terminate its supply contract with its largest customer, the Southwire Company, given the potential plant closure effective August 20th. If a competitively priced definitive power contract cannot be obtained, CAKY intends to curtail all smelter operations on August 20, 2013, when its current power contract with Big Rivers Electric Corporation expires. In addition, CAKY issued a conditional notice to the employees at the Hawesville smelter of its intent to curtail all plant operations effective August 20, 2013. The announcement was made pursuant to the federal Worker Adjustment and Retraining Notification Act ("WARN"). The WARN notice specifies that the plant will be curtailed unless Hawesville can gain access to competitively priced electric power.
Century Aluminum of West Virginia reaches agreement with PBGC for future pension contributions
In April 2013, CAWV entered into a settlement agreement with the PBGC regarding an alleged “cessation of operations” at its Ravenswood facility as a result of the curtailment of operations at the facility. While CAWV does not believe that a “cessation of operations” has occurred, CAWV has reached an agreement with the PBGC to resolve the matter. Pursuant to the terms of the agreement, CAWV will make additional contributions (above any minimum required contributions) to its defined benefit pension plans totaling approximately $17.4 million over the term of the agreement, which runs through 2016. In April 2013, we made the first scheduled contribution pursuant to this agreement of $5.9 million.
Century signs lease for Chicago corporate headquarters
In February 2013, we signed a 10-year operating lease for office space for our corporate headquarters in Chicago, Illinois. We have completed our relocation to Chicago, but we expect to continue to incur relocation expenses through the end of the year.

Six months ended June 30, | $ | 653.2 |  | $ | 649.8 |  | $ | 3.4 |  | 0.5 | %

Lower price realizations for our primary aluminum shipments in the three months ended June 30, 2013 were due to lower LME prices for primary aluminum, which were partially offset by increased premiums. The lower price realizations resulted in a $23.5 million decrease in sales. Higher shipment volumes had a $31.8 million positive impact on net sales. Direct shipments from our four operating smelters increased 12,453 metric tons in the three months ended June 30, 2013 compared to the same period in 2012, due to the acquisition of the Sebree smelter on June 1, 2013. Toll shipments increased 2,989 metric tons relative to the same period last year.
Lower price realizations for our primary aluminum shipments in the six months ended June 30, 2013 were due to lower LME prices for primary aluminum, which were partially offset by increased premiums. The lower price realizations resulted in a $26.4 million sales decrease. Higher shipment volumes had a $29.8 million positive impact on net sales. Direct shipments from our four operating smelters increased 11,838 metric tons in the six months ended June 30, 2013 compared to the same period in 2012, due to the acquisition of the Sebree smelter on June 1, 2013. Toll shipments increased 2,413 metric tons relative to the same period last year.

During the three months ended June 30, 2013, lower price realizations, net of LME-based alumina cost and LME-based power cost, decreased gross profit by $18.0 million, with volume and mix increasing gross profit by $0.7 million. In addition, we experienced $7.7 million in net cost decreases, relative to the same period in 2012, comprised of: lower costs for materials, supplies and maintenance, $9.5 million; offset by higher power and natural gas costs at our U.S. smelters, $0.8 million; other cost increases, $0.4 million and increased depreciation, $0.6 million.
During the six months ended June 30, 2013, lower price realizations, net of LME-based alumina cost and LME-based power cost, decreased gross profit by $9.3 million, with volume and mix increasing gross profit by $1.6 million. In addition, we experienced $18.1 million in net cost decreases, relative to the same period in 2012, comprised of: lower costs for materials, supplies and maintenance, $20.5 million; lower power and natural gas costs at our U.S. smelters, $1.5 million; offset by other cost increases, $3.2 million and increased depreciation, $0.7 million.
As part of the accounting for the purchase of the Sebree facility, we recorded a $36.6 million estimated liability subject to adjustment for the power contract we assumed based on the difference between the forecasted contract rate and market power rates through the contract termination date in January 2014. This liability will be fully amortized over the period from June 1, 2013 through January 31, 2014 resulting in a credit to our depreciation and amortization expense. During the three and six months ended June 30, 2013, the credit was $2.7 million reflecting one month of amortization under Century's ownership.
Decreases in LME prices at the end of the second quarter of 2013 resulted in a decrease in the market value of our inventory relative to its cost basis. As a result we recorded a lower of cost or market (LCM) inventory reserve of $16.1 million which was $10.2 million greater than the reserve recorded at March 31, 2013 and resulted in a charge to cost of goods sold for the three months ended June 30, 2013 of $10.2 million. At the end of the second quarter of 2012, a similar situation occurred. Decreases in LME prices resulted in a decrease in the market value of our inventory relative to its cost basis and we increased our recorded LCM reserve by $5.4 million resulting in a charge to cost of goods sold for the three months ended June 30, 2012 of $5.4 million. This resulted in a quarter to quarter decrease in gross profit of $4.8 million.
During the six months ended June 30, 2013, the decrease in the market value of our inventory relative to its cost basis resulted in a LCM reserve being recorded of $16.1 million which resulted in a charge to cost of goods sold of $16.1 million. During the six months ended June 30, 2012, decreases in market value of our inventory relative to its cost basis resulted in a LCM reserve being recorded of $8.2 million which was $11.6 million less than the reserve recorded at December 31, 2011 resulting in a credit to cost of goods sold of $11.6 million as the impaired materials were utilized. This resulted in a period to period decrease in gross profit of $27.7 million.

Other operating expenses - net (in millions) | 2013 | 2012 | $ Difference | % Difference
Three months ended June 30, | $ | 3.0 |  | $ | 3.8 |  | $ | (0.8 | ) | (21.1 | )%
Six months ended June 30, | $ | 4.1 |  | $ | 7.5 |  | $ | (3.4 | ) | (45.3 | )%

Other operating expenses - net is primarily related to items associated with Ravenswood. Charges at the facility have been relatively stable during the three and six months ended June 30, 2013 and 2012, except during the first quarter of 2013, when we reduced the facility's accrued legal liabilities by approximately $2.2 million to reflect the settlement with Ingram.

Selling, general and administrative expenses (in millions) | 2013 | 2012 | $ Difference | % Difference
Three months ended June 30, | $ | 15.2 |  | $ | 7.2 |  | $ | 8.0 |  | 111.1 | %
Six months ended June 30, | $ | 31.5 |  | $ | 15.6 |  | $ | 15.9 |  | 101.9 | %

During the three and six months ended June 30, 2013, we experienced increased selling, general and administrative charges due to: relocation and severance expenses related to moving our headquarters to Chicago; litigation matters and accruals for our variable compensation program. In addition, we have incurred general and administrative expenses in 2013 related to the integration of Century Vlissingen anode facility into our business. Upon the restart of Century Vlissingen operations, these costs will be included in cost of goods sold and not recorded in selling, general and administrative expenses. We also incurred selling, general and administrative expenses associated with the newly acquired Sebree facility.

The net gain on forward contracts for the three and six months ended June 30, 2013 was primarily the result of an increase in the fair value of a derivative embedded in the E.ON contingent liability. This change in fair value resulted in unrealized gains of $0.4 million and $16.1 million for the three and six months ended June 30, 2013, respectively. The net gain (loss) on forward contracts for the three and six months ended June 30, 2012 related primarily to marking-to-market and recording settlements of option contracts that were put in place to provide partial downside price protection for our domestic facilities. As of June 30, 2012, all of these option contracts were settled.

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 acquisition date. The purchase price allocation is preliminary and subject to change based on the finalization of the valuation of assets and liabilities. Based on the preliminary purchase price allocation, we recorded a gain on bargain purchase of $2.0 million. The gain on bargain purchase reflects the current LME market and the market risk associated with the long term power supply for the facility. See Note 2 Business Combination to the consolidated financial statements included herein for additional information.

As a result of the tender offer and redemption of the 8% senior secured notes due 2014, we recorded charges of $3.3 million for loss on early extinguishment of debt. We determined the tender and redemption of the 8.0% Notes should be treated as an extinguishment of the debt and accordingly, we recorded a loss on early extinguishment of debt in the second quarter of 2013. The loss on early extinguishment of debt consisted of the write-off of deferred financing costs and the debt discount associated with the 8.0% Notes, as well as the tender premium paid as part of the 8.0% Notes Tender. See Note 10 Debt to the consolidated financial statements included herein for additional information.

Our 2013 and 2012 income tax expense was primarily driven by our earnings in Iceland, with some additional income tax expense due to U.S. state income taxes. In 2013, as a result of the recently completed audit by the Internal Revenue Service, we reduced our interest receivable of approximately $1.0 million with a charge to income tax expense in the current period.

Liquidity and Capital Resources
Liquidity
Our principal sources of liquidity are available cash, cash flow from operations and available borrowings under our revolving credit facility. We have also raised capital in the past through the public equity and debt markets although we have no commitments in place for such transactions. We regularly explore various other financing alternatives. Our principal uses of cash are the funding of operating costs (including postretirement benefits), maintenance of curtailed production facilities, payments of principal and interest on our outstanding debt, the funding of capital expenditures, investments in our growth activities and in related businesses, repurchases of common stock, working capital and other general corporate requirements.
Our consolidated cash and cash equivalents balance at June 30, 2013 was approximately $128 million compared to $184 million at December 31, 2012. We received a customer receivable payment of approximately $22 million in July 2013, one business day after its June 28th due date. The receipt of this payment is not reflected in the June 30, 2013 consolidated cash and cash equivalents balance. In May 2013, we entered into the Amended and Restated Loan and Security Agreement (the “New Credit Facility”) modifying the credit facility signed July 1, 2010. The New Credit Facility extended the term through May 24, 2018 and provides for borrowings of up to $137.5 million in the aggregate, including up to $80 million under a letter of credit sub-facility. As of June 30, 2013, our credit facility had no loan amounts outstanding and approximately $64 million of net availability. We have approximately $74 million of letters of credit outstanding under our credit facility. Future curtailments of domestic production capacity would reduce domestic accounts receivable and inventory, which comprise the borrowing base of our credit facility, and would result in a corresponding reduction in availability under the credit facility. The acquisition of the Sebree smelter increased domestic accounts receivable and inventory and resulted in a corresponding increase in availability under the credit facility.
In June 2013, we issued $250 million in 7.5% senior secured notes payable that will mature in 2021.
In December 2012, February 2013, March 2013 and April 2013, Nordural ehf participated in the 50/50 ISK Auctions (the “Auctions”) sponsored by the Central Bank of Iceland (“CBI”) and may participate in future auctions. The Auctions allow authorized investors to exchange foreign currency for Icelandic kronur ("ISK") with 50% exchanged at the official rate set by the CBI and 50% exchanged at auction. The ISK received in the Auctions must be invested in Iceland for a minimum of five years.
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, 2013 and management’s estimate of the LME forward market, we believe that we will not be required to make payments on the E.ON contingent obligation during the term of the agreement through 2028. See Note 5 Derivative and hedging instruments and Note 10 Debt to the consolidated financial statements included herein for additional information.
In August 2011, our Board of Directors approved a $60 million stock repurchase program. Through June 30, 2013, we had expended approximately $50 million under the program. At June 30, 2013, we had approximately $10 million remaining under the repurchase program authorization. The repurchase program may be suspended or discontinued at any time.
In April 2013, CAWV entered into a settlement agreement with the PBGC regarding an alleged “cessation of operations” at its Ravenswood facility as a result of the curtailment of operations at the facility. While CAWV does not believe that a “cessation of operations” has occurred, CAWV has reached an agreement with the PBGC to resolve the matter. Pursuant to the terms of the agreement, CAWV will make additional contributions (above any minimum required contributions) to its defined benefit pension plans totaling approximately $17.4 million over the term of the agreement, which runs through 2016. In April 2013, CAWV made the first scheduled contribution pursuant to this agreement of $5.9 million. We expect to make additional annual contributions through 2016 totaling approximately $11.5 million.
45

Based on current actuarial and other assumptions, we expect to make minimum required contributions to the qualified defined benefit plans we sponsor of approximately $3.6 million during 2013 in addition to the contributions required pursuant to the PBGC settlement. In the six months ended June 30, 2013, we have made contributions to these plans of $7.4 million. We may choose to make additional contributions to these plans from time to time at our discretion.
Under an agreement with the Government of Iceland, Nordural Grundartangi ehf agreed to prepay taxes during 2012, 2011 and 2010 as an advance levy of income taxes and other governmental taxes for the period of 2013 through 2018. The amount of prepaid taxes paid through December 31, 2012 was approximately $9.6 million. The prepaid taxes will offset taxes otherwise payable in equal installments over the period 2013 through 2018. In 2013, approximately $1.6 million of the prepaid taxes will be used to offset income taxes due. In 2013, we expect to make estimated net income tax payments in Iceland of approximately $8.6 million. Through June 30, 2013, we made approximately $5.3 million of these payments.
We paid approximately $13.1 million in withholding taxes for intercompany dividend payments in Iceland in the third quarter of 2012 and approximately $8.3 million in first quarter of 2013, which we expect will be refunded in the fourth quarter of 2013. We expect to pay approximately $9.6 million in the third quarter of 2013, which we expect will be refunded in 2014. The withholding taxes and associated refunds are payable in Icelandic krona (“ISK”) and we are subject to foreign currency risk associated with fluctuations in the value of the U.S. dollar as compared the ISK.
In May 2013, we received a US federal income tax refund of $5.0 million upon the notification from the Internal Revenue Service that it had finalized the review of our federal income tax returns for the tax years 2008, 2009, and 2010 and refund years of 2004, 2005, 2006, and 2007.
In June 2012, Nordural Grundartangi entered into a new supplemental power contract with Landsvirkjun. The supplemental power contract, which will expire in October 2029 (or upon the occurrence of certain earlier events), will provide Nordural Grundartangi with supplemental power, as Nordural Grundartangi may request from time to time, at LME-based variable rates. Nordural Grundartangi has agreed to make certain prepayments to Landsvirkjun in connection with the contract, which will reduce the price paid for power at the time of consumption. As of June 30, 2013, these power prepayments totaled approximately $1.8 million. We expect the amount of the prepayment to continue to grow slowly and we do not expect to realize the benefits from the prepayments in the near term.
Capital Resources
We intend to finance our future recurring capital expenditures from available cash, our cash flow from operations and available borrowings under our revolving credit facility. 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 to issue additional debt or equity securities, or to issue these securities on attractive terms, due to a number of factors including a lack of demand, unfavorable pricing, poor economic conditions, unfavorable interest rates, or our financial condition or credit rating at the time. Future uncertainty in the U.S. and international markets and economies may adversely affect our liquidity, our ability to access the capital markets and our financial condition.
Capital expenditures for the six months ended June 30, 2013 were $22.9 million, $2.6 million of which was related to the Helguvik project and $3.8 million was related to the Century Vlissingen restart. The balance principally related to an expansion project at Grundartangi that is expected to increase production capacity by approximately 40,000 mtpy over the next four years. The remaining amounts are related to upgrading production equipment, improving facilities and complying with environmental requirements. We believe capital spending in 2013, excluding the activity on the Century Vlissingen and Helguvik projects, will be approximately $40 to $45 million.
46

On June 1, 2013, we acquired the Sebree aluminum smelter from a subsidiary of RTA. The purchase price for the acquisition was $61 million (subject to customary working capital adjustments), of which we have paid $48 million as of June 30, 2013. The remaining portion of the purchase price will be paid following final determination of the applicable working capital adjustments, which will be determined based on the amount of working capital transferred to Century Sebree at closing versus a target working capital amount of $71 million. The transaction was funded with the available cash on hand. See Note 2 in the consolidated financial statements contained herein for additional information.
In order to restart the first 75,000 metric tons of annual anode capacity at Century Vlissingen, we currently intend to make approximately $30 to $35 million in capital expenditures in 2013. Through June 30, 2013, we have spent approximately $3.7 million on this project. We expect the first 75,000 metric tons of capacity will be restarted in late 2013 and will provide an anode supply to replace third-party anode supply contracts terminated in 2013. Following the restart of the first 75,000 metric tons, we currently intend to make approximately $10 million in additional expenditures over the following three years in order to restart an additional 75,000 metric tons of capacity.
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 costs would be approximately $20 million. We are continuing to negotiate with the power suppliers to the project to remove all the remaining conditions to their obligations to supply contracted power. The timing of the power availability together with other factors will determine the timing of resumption of major construction activity at Helguvik. We expect that the portion of capital expenditures for this project that we will fund from our existing cash and operating cash flow will be approximately $1 million per quarter until the restart of major construction activities. We cannot, at this time, predict when the restart of major construction activity will occur.
Historical
Our statements of cash flows for the six months ended June 30, 2013 and 2012 are summarized below:

| Six months ended June 30,
| 2013 | 2012
| (dollars in thousands)
Net cash provided by (used in) operating activities | $ | 22,976 |  | $ | (1,615 | )
Net cash used in investing activities | (71,057 | ) | (21,241 | )
Net cash used in financing activities | (8,364 | ) | (4,033 | )
Net change in cash and cash equivalents | $ | (56,445 | ) | $ | (26,889 | )

Net cash provided by operating activities in the six months ended June 30, 2013 was $23.0 million compared to net cash used by operating activities of $1.6 million in the first six months of 2012. The increase in cash from operations in 2013 was due to improved conversion cost performance primarily due to lower power and carbon costs and lower pension and OPEB benefit contributions, which were partially offset by the impact of lower LME prices.
Our net cash used in investing activities for the first six months of 2013 was $71.1 million compared to $21.2 million in the six months ended June 30, 2012. The increase in cash used was primarily due to payments for the purchase of the Sebree smelter in 2013 of $48 million and higher capital expenditures for the Grundartangi expansion project that is expected to increase production capacity at Grundartangi by approximately 40,000 mtpy over the next four years. We purchased carbon anode assets and made additional improvements totaling $14.5 million in the second quarter of 2012. We continue to make capital expenditures for the restart of those assets and in the first six months of 2013, we expended $3.7 million on this project.
Our net cash used in financing activities for the first six months ended June 30, 2013 was $8.4 million, which was primarily related to the net costs associated with the extinguishment of our 8.0% Notes due in 2014 and the issuance of our 7.5% Notes due in 2021. Our net cash used in financing activities for the six months ended June 30, 2012 was $4.0 million for the repurchase of our common stock.

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 11 Commitments and contingencies to the consolidated financial statements included herein for additional information.

Item 3. Quantitative and Qualitative Disclosures about Market Risk
Commodity price risk
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 for our domestic production. In addition, we manage our exposure to fluctuations in our costs by purchasing certain of our alumina and power requirements under supply contracts with prices tied to the same indices as our aluminum sales contracts (the LME price of primary aluminum). Our risk management activities do not include any trading or speculative transactions.
Apart from the Glencore Metal Agreement, the Glencore Sweep Agreement, the Glencore Nordural Metal Agreement, the RTA Metal Agreement and the Southwire Metal Agreement, we had the following forward delivery contractual commitments:
Other forward delivery contracts

| June 30, 2013 | December 31, 2012
| (in metric tons)
Other forward delivery contracts – total | 50,181 |  | 88,827 |
Other forward delivery contracts – Glencore | 2,010 |  | 1,811 |

We had no outstanding primary aluminum forward financial sales contracts at June 30, 2013. We had no fixed price forward financial contracts to purchase aluminum at June 30, 2013.
Foreign currency
We are exposed to foreign currency risk due to fluctuations in the value of the U.S. dollar as compared to the Icelandic krona (“ISK”), 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 in Icelandic banks, 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 expect to incur capital expenditures for capital investments in Century Vlissingen in the Netherlands over the next three years. In addition, Century Vlissingen labor costs, maintenance costs and other local services will be 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. A significant portion of the capital expenditures for the Helguvik project are forecasted to 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, 2013, we had no foreign currency forward contracts outstanding.
Natural Economic Hedges
The following estimate of our exposure to the commodity price of aluminum is necessarily limited, as it does not take into consideration our inventory or forward delivery contracts, or the offsetting impact on the sales price of primary aluminum products. Our alumina contracts are indexed to the LME price for primary aluminum and provide a natural hedge for approximately 16% of our production. As of June 30, 2013, approximately 34% of our production for 2013 was hedged by our LME-based alumina contracts and by Grundartangi’s electrical power and tolling contracts.
Risk Management
Our metals, foreign currency and natural gas risk management activities are subject to the control and direction of senior management within guidelines established by Century’s Board of Directors. These activities are regularly reported to Century’s Board of Directors.
49

Item 4. Controls and Procedures
a. Evaluation of Disclosure Controls and Procedures
As of June 30, 2013, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our principal financial officer, of the effectiveness of our disclosure controls and procedures. Based upon that evaluation, our management, including the Chief Executive Officer and our principal financial officer, has concluded that our disclosure controls and procedures were effective as of June 30, 2013.
b. Changes in Internal Controls over Financial Reporting
During the three months ended June 30, 2013, there were no changes in our internal controls over financial reporting that materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting. On June 1, 2013, we acquired the Sebree smelter and we are currently in the process of extending our internal controls over financial reporting to Sebree's operations.
50

PART II – OTHER INFORMATION
Item 1. Legal Proceedings
In addition to the matters discussed below, we may from time to time be involved in claims, proceedings and litigation arising from our business and property ownership. We believe, based on currently available information, that the results of such proceedings, in the aggregate, will not have a material adverse effect on our financial condition.
We have been named as a defendant in a lawsuit filed by our former Chief Executive Officer, Logan Kruger, alleging breach of contract. The lawsuit alleges that Century anticipatorily breached the employment and severance protection agreements between Century and Mr. Kruger and that Century is obligated to make various severance payments in excess of $20 million to Mr. Kruger under such agreements. In addition, the complaint seeks unspecified damages, including costs and attorneys’ fees. The trial court has transferred the matter to an arbitration panel for resolution. We believe these claims are without merit and intend to defend ourselves against them. The arbitration hearing is currently scheduled for the third quarter of 2013.
In March 2011, the purported stockholder class actions pending against us consolidated as In re: Century Aluminum Company Securities Litigation were dismissed with prejudice by the United States District Court for the Northern District of California. The plaintiffs in the class actions allege that we improperly accounted for cash flows associated with the termination of certain forward financial sales contracts which accounting allegedly resulted in artificial inflation of our stock price and investor losses. Plaintiffs are seeking rescission of our February 2009 common stock offering, unspecified compensatory damages, including interest thereon, costs and expenses and attorneys’ fees. In March 2011, plaintiffs filed a notice of appeal to the order and judgment entered by the trial court. In January 2013, the U.S. Court of Appeals for the Ninth Circuit (the "Ninth Circuit") affirmed the trial court's decision. Plaintiffs filed a motion for rehearing or for hearing en banc, which the Ninth Circuit denied in April 2013.
In February 2010, our subsidiary, CAWV, was named as a defendant in a lawsuit filed by Ingram Barge Company ("Ingram") in the United States District Court for the Middle District of Tennessee. The lawsuit alleges that CAWV breached two barging contracts with Ingram by failing to consume a specified amount of barging services as a result of the curtailment of operations at Ravenswood. In May 2013, the parties entered into an a settlement agreement pursuant to which CAWV agreed to pay Ingram approximately $1.6 million and made certain commitments to Ingram with respect to future contracts.
In April 2013, our subsidiary Nordural Grundartangi, received a ruling in an arbitration case involving two of its power suppliers, HS Orka and Orkuveita Reykjavikur. Under the arbitration award, Nordural Grundartangi is restricted from reducing power under its existing power contracts with HS Orka and Orkuveita Reykjavikur in order to take power under a separate power contract with Orkuveita Reykjavikur originally intended to be used at Helguvik. Nordural Grundartangi remains entitled to take power under the Orkuveita Reykjavikur 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 Orka damages and Nordural Grundartangi paid $1.5 million to HS Orka in full satisfaction of such award. The tribunal ordered each party to pay its own legal fees and costs. Orku veita Reykjavikur has subsequently brought a claim for damages against Nordural Grundartangi based on the arbitration ruling. Nordural Grundartangi believes these claims are without merit and intends to defend itself against them.
For further information regarding legal proceedings pending against us as of June 30, 2013, refer to Note 11 Commitments and contingencies to the consolidated financial statements included herein.
Item 1A. Risk Factors
Other than below, there have been no material changes from the risk factors previously disclosed under the heading “Risk Factors” in our 2012 Annual Report on Form 10-K for the fiscal year ended December 31, 2012. You should carefully consider the risk factors set forth below and those contained in our Annual Report on Form 10-K and the other information set forth elsewhere in this Quarterly Report on Form 10-Q. You should be aware that these risk factors and other information may not describe every risk facing our Company. 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.
51

Proposed new LME warehousing rules could cause metal premiums to decrease.
The LME has announced proposed new rules that would require LME warehouses, under certain conditions, to deliver out more aluminum than they take in. If implemented, these new rules could cause an increase in the supply of aluminum to enter the physical market and may cause local delivery premiums and LME aluminum prices to fall. Declines in aluminum prices and local delivery premiums reduce our earnings and cash flows. Future downturns in aluminum prices may significantly reduce the amount of cash available to meet our obligations and fund our long-term business strategies and could have a material adverse effect on our business, financial conditions, results of operations and liquidity.
If we do not achieve the anticipated benefits of the Sebree acquisition, our business and the market price of our common stock may be adversely affected.
Consummation of the Sebree acquisition occurred in June 2013.
We are subject to numerous risks following the consummation of the Sebree acquisition, including that:

• | our senior management's attention may be diverted from the management of our existing business as we integrate the acquired Sebree operations, which may disrupt our existing operations and relationships with our customers;

• | we may incur costs and expenses associated with any unidentified or potential liabilities;

• | the Sebree acquisition may not perform as well as we anticipate;

• | unforeseen difficulties may arise in integrating the acquired Sebree operations into our existing operations; and

• | Sebree has issued a 12-month notice to terminate its power contract with Kenergy (the same power provider as our Hawesville facility), effective January 31, 2014. If we are unable to enter into a new contract for the facility, we may be unable to operate it at a profitable level or at all.

Accordingly, the Sebree acquisition might not ultimately improve our competitive position and business prospects as anticipated and may subject us to additional liabilities that could have a material adverse effect on our business, financial condition, results of operations and liquidity. Furthermore, if we fail to realize the anticipated benefits of the Sebree acquisition, the market price of our common stock could decline to the extent that the market price reflects those anticipated benefits.
If we are unable to successfully negotiate better power pricing at our Hawesville and Sebree smelters, we might close these facilities.
In August 2012, CAKY issued a 12-month notice to terminate the Hawesville Power Agreement with Kenergy. Pursuant to the termination notice, the Hawesville Power Agreement will terminate on August 20, 2013. Similarly, in January 2013, Sebree issued a 12-month notice to terminate the Sebree Power Agreement with Kenergy. Pursuant to the termination notice, the Sebree Power Agreement will terminate on January 31, 2014. Under current economic conditions, we have determined that these smelters are not economically viable with their power rates and that we must obtain better power pricing to maintain their viability. Upon termination of the Hawesville Power Agreement or Sebree Power Agreement, Century is required to make alternative power arrangements or curtail activity at, in each case at the respective plant. Our ability to enter into alternative power arrangements is limited by Kentucky state law.
Although CAKY announced on April 29, 2013 that it reached a tentative agreement with Kenergy and Big Rivers on the framework for providing market priced power to the Hawesville smelter, the definitive agreements that we subsequently negotiated with Kenergy and Big Rivers are subject to the approvals from various third parties, including the KPSC. There can be no assurance that any such agreement will receive the necessary third party approvals. If a new power arrangement is not reached prior to August 20, 2013, the Hawesville plant will have to be curtailed. We also intend to seek a market-based power contract for Sebree similar to the tentative agreement we have reached for Hawesville, but no assurance can be given that we will be able to obtain one. If a new power arrangement for Sebree is not reached prior to January 31, 2014, the Sebree plant will have to be curtailed. A curtailment of either the Hawesville or Sebree plants (or both of them) would impose various costs on us that could have a material adverse effect on our business, financial condition, results of operations and liquidity.
52

In addition, uncertainty regarding the future operation of these smelters may damage our relationships with our customers, suppliers, employees and other stakeholders, whether or not these smelters are ultimately curtailed. On April 16, 2013, for example, we issued a conditional WARN notice to our employees in Hawesville and we gave notice to terminate the supply contract with Hawesville's largest customer, in each case given the potential plant closure effective August 20, 2013. We may also need to take actions to terminate other customer and supply contracts or curtail individual potlines well in advance of any plant closure. Customers and suppliers may also become unwilling to renew existing contracts or enter into new contracts with us. It may also become more difficult to attract and retain employees. Such actions and events could have a material adverse effect on our business, financial condition, results of operations and liquidity.

Item 5. Other Information
Disclosure Pursuant to Section 219 of the Iran Threat Reduction & Syria Human Rights Act
Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 (“ITRA”), effective August 10, 2012, added a new subsection (r) to Section 13 of the Exchange Act, which requires issuers that file periodic reports with the SEC to disclose in their annual and quarterly reports whether, during the reporting period, they or any of their “affiliates” (as defined in Rule 12b-2 under the Exchange Act) have knowingly engaged in specified activities or transactions relating to Iran, including activities not prohibited by U.S. law and conducted outside the U.S. by non-U.S. affiliates in compliance with applicable laws. Issuers must also file a notice with the SEC if any disclosable activities under ITRA have been included in an annual or quarterly report.
Because the SEC defines the term “affiliate” broadly, our largest stockholder may be considered an affiliate of the Company despite the fact that the Company has no control over its actions or the actions of its affiliates. As such, pursuant to Section 13(r)(1)(D)(iii) of the Exchange Act, the Company hereby discloses the following information provided by our largest stockholder regarding transactions or dealings with entities controlled by the Government of Iran (“GOI”):
During the second quarter of 2013, non-U.S. affiliates of the largest stockholder of the Company (“Stockholder Affiliates”) entered into sales contracts for agricultural products as well as purchase contracts for metals with Iranian entities, which are either fully or majority owned by the GOI. The GOI is in the process of privatizing some of these entities. All transactions were conducted in compliance with applicable sanction laws and, where required, with the necessary prior approvals by the relevant governmental authorities.
The gross revenue of the non-U.S Stockholder Affiliates related to these transactions did not exceed the value of $111 million for the second quarter of 2013 ending June 30, 2013. This figure includes the gross revenue of goods sold in 2013 but purchased in previous years. The non-U.S. Stockholder Affiliates do not allocate net profit on a country-by-country or activity-by-activity basis, but estimate that the net profit attributable to the transactions with the GOI would not exceed a small fraction of the gross revenue from such transactions. It is not possible to determine accurately the precise net profit attributable to these transactions.
The non-U.S. Stockholder Affiliates believe that these transactions disclosed above do not constitute violations of applicable sanctions laws administered by the U.S. Department of the Treasury, Office of Foreign Assets Control, and are not the subject of any enforcement actions under Iran sanction laws.
In accordance with applicable U.S. and foreign sanctions laws, the non-U.S. Stockholder Affiliates expect to continue to engage in similar activities in the future.
We had no transactions or activities requiring disclosure under ITRA, nor were we involved in the transactions described in this section. As of the date of this report, we are not aware of any other activity, transaction or dealing by it or any of its affiliates during the second quarter of 2013 ending June 30, 2013 that requires disclosure in this report under Section 13(r) of the Exchange Act.
