CENTURY ALUMINUM COMPANY
Condensed Notes to the Consolidated Financial Statements
Nine months ended September 30, 2022 and 2021
(amounts in millions, except share and per share amounts)
(Unaudited)
1.General
The accompanying unaudited interim consolidated financial statements of Century Aluminum Company should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2021. 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 nine months of 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. Throughout this Form 10-Q, and unless expressly stated otherwise or as the context otherwise requires, "Century Aluminum," "Century," the "Company," "we," "us," "our" and "ours" refer to Century Aluminum Company and its consolidated subsidiaries.
2.Curtailment of Operations - Hawesville
On June 22, 2022, our subsidiary, Century Aluminum of Kentucky ("CAKY"), issued a Worker Adjustment and Retraining Notification Act ("WARN") notice at its Hawesville, Kentucky aluminum smelter related to a temporary curtailment of plant operations within 60 days as a result of current market conditions, including historically high energy costs and declining London Metal Exchange ("LME") prices. We have since fully curtailed production at the facility and expect to continue to maintain the plant with the intention of restarting operations when market conditions permit, including energy prices returning to more normalized levels and aluminum prices maintaining levels that can support the on-going costs and capital expenditures necessary to restart and operate the plant.
As the curtailment represents a significant adverse change in the extent and manner in which the Hawesville smelter will be used, we accordingly evaluated the Hawesville asset group for recoverability. As the carrying value of the Hawesville asset group was determined to not be recoverable based on the estimated undiscounted cash flows expected to be generated over the life of the asset group, an impairment charge of $159.4 million was recognized to write down the asset group to its estimated fair value of $15.0 million. We classified the estimated remaining fair value of the long lived assets within Level 3 of the fair value hierarchy as its fair value was determined based on recent comparable transactions with inputs that are not readily observable in the market. We recognized $12.6 million of expense through the third quarter related to wages and severance triggered by our issuance of the WARN notice and excess capacity charges, partially offset by final plant idling activities. We also recognized a non-cash other postretirement benefits ("OPEB") curtailment gain, net totaling $8.0 million for the three and nine months ended September 30, 2022. See Note 13. Components of net periodic benefit cost to the consolidated financial statements included herein for additional information.
3.Related Party Transactions
The significant related party transactions occurring during the nine months ended September 30, 2022 and 2021 are described below. We believe all of our transactions with related parties are at prices that approximate market.
Glencore Ownership
As of September 30, 2022, Glencore plc and its affiliates (together "Glencore") beneficially owned 42.9% of Century’s outstanding common stock (46.3% on a fully-diluted basis assuming the conversion of all of the Series A Convertible Preferred Stock) and all of our outstanding Series A Convertible Preferred Stock. See Note 7. Shareholders' Equity for a description of our outstanding Series A Convertible Preferred Stock. Century and Glencore enter into various transactions from time to time such as the purchase and sale of primary aluminum, purchase and sale of alumina and other raw materials, tolling agreements as well as forward financial contracts and borrowing and other debt transactions.

Sales to Glencore
For the three months ended September 30, 2022 and 2021, we derived approximately 63.5% and 60.3%, respectively, of our consolidated net sales from Glencore.
Glencore purchases aluminum produced at our U.S. smelters at prices based on the LME plus the Midwest regional delivery premium plus any additional market-based product premiums. Glencore purchases aluminum produced at our Grundartangi, Iceland smelter at prices primarily based on the LME plus the European Duty Paid premium plus any additional market-based product premiums.
We have entered into agreements with Glencore pursuant to which we sell certain amounts of alumina at market-based prices. For the three and nine months ended September 30, 2022, we recorded $4.9 million and $18.8 million of revenue related to alumina sales to Glencore, respectively. For the three and nine months ended September 30, 2021, we recorded $5.5 million and $16.9 million of revenue related to alumina sales to Glencore, respectively.
Purchases from Glencore
We purchase a portion of our alumina and certain other raw material requirements from Glencore. Alumina purchases from Glencore during the three months ended September 30, 2022 were priced based on published alumina and aluminum indices as well as fixed prices.
Financial Contracts with Glencore
We have certain financial contracts with Glencore. See Note 14. Derivatives regarding these forward financial sales contracts.

5.Fair Value Measurements
We measure certain of our assets and liabilities at fair value. Fair value represents 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.
In general, reporting entities should apply valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs. Observable inputs are developed using market data and reflect assumptions that market participants would use when pricing the asset or liability. Unobservable inputs are developed using the best information available about the assumptions that market participants would use when pricing the asset or liability.
The fair value hierarchy provides transparency regarding the inputs we use to measure fair value. We categorize each fair value measurement in its entirety into the following three levels, based on the lowest level input that is significant to the entire measurement:
Level 1 Inputs - quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.
Level 2 Inputs - inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
Level 3 Inputs - significant unobservable inputs for the asset or liability.

When valuing Level 3 assets and liabilities, we use certain significant unobservable inputs. Management incorporates various inputs and assumptions including forward commodity prices, commodity price volatility and macroeconomic conditions, including interest rates and discount rates. Our estimates of significant unobservable inputs are ultimately based on our estimates of risks that market participants would consider when valuing our assets and liabilities.
The following table presents the inputs for recurring fair value measurements categorized within Level 3 of the fair value hierarchy, along with information regarding significant unobservable inputs used to value Level 3 assets and liabilities:

Our announcement on June 22, 2022 to curtail operations of the Hawesville smelter represented a significant adverse change in the extent and manner in which this smelter will be used, and we accordingly evaluated the Hawesville asset group for recoverability. As the carrying value of the Hawesville asset group was determined to not be recoverable based on the estimated undiscounted cash flows expected to be generated over the life of the asset group, we wrote the asset group down to its estimated fair value of $15.0 million.
The following table presents the inputs for this non-recurring fair value measurements categorized within Level 3 of the fair value hierarchy, along with information regarding the significant unobservable inputs used:

6. Earnings (Loss) Per Share
Basic earnings (loss) per share ("EPS") amounts are calculated by dividing net income (loss) allocated to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive securities.
The following table shows the basic and diluted earnings (loss) per share:

7.    Shareholders’ Equity
Common Stock
As of September 30, 2022 and December 31, 2021, we had 195,000,000 shares of common stock, $0.01 par value per share, authorized under our Restated Certificate of Incorporation, of which 98,533,750 shares were issued and 91,347,229 shares were outstanding at September 30, 2022, and 98,418,132 shares were issued and 91,231,611 shares were outstanding at December 31, 2021.
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.
Preferred Stock
As of September 30, 2022 and December 31, 2021, we had 5,000,000 shares of preferred stock, $0.01 par value per share, authorized under our Restated Certificate of Incorporation. Our Board of Directors may issue preferred stock in one or more series and determine for each series the dividend rights, conversion rights, voting rights, redemption rights, liquidating preferences, sinking fund terms and the number of shares constituting that series, as well as the designation thereof. Depending upon the terms of preferred stock established by our Board of Directors, any or all of the preferred stock could have preference over the common stock with respect to dividends and other distributions and upon the liquidation of Century. In addition, issuance of any shares of preferred stock with voting powers may dilute the voting power of the outstanding common stock.
Series A Convertible Preferred Stock
Shares Authorized and Outstanding. In 2008, we issued 160,000 shares of our Series A Convertible Preferred Stock. Glencore holds all of the issued and outstanding Series A Convertible Preferred Stock. At September 30, 2022 and December 31, 2021, there were 58,046 shares and 58,542 shares of Series A Convertible Preferred Stock outstanding, respectively.
The issuance of common stock under our stock incentive programs, debt exchange transactions and any stock offering that excludes Glencore participation triggers anti-dilution provisions of the preferred stock agreement and results in the automatic conversion of Series A Convertible Preferred Stock shares into shares of common stock. The conversion ratio of preferred to common shares is 100 shares of common stock for each share of preferred stock.   
The Common and Preferred Stock table below contains additional information about preferred stock conversions during the nine months ended September 30, 2022 and September 30, 2021.

Stock Repurchase Program
In 2011, our Board of Directors authorized a $60.0 million common stock repurchase program and during the first quarter of 2015, our Board of Directors increased the size of the program by $70.0 million. Under the program, Century is authorized to repurchase up to $130.0 million of our outstanding shares of common stock, from time to time, on the open market at

CENTURY ALUMINUM COMPANY
Condensed Notes to the Consolidated Financial Statements (continued)
(amounts in millions, except share and per share amounts)
(Unaudited)
prevailing market prices, in block trades or otherwise. The timing and amount of any shares repurchased will be determined by our management based on its evaluation of market conditions, the trading price of our common stock and other factors. The stock 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.
We have repurchased 7,186,521 shares of common stock under the program for an aggregate purchase price of $86.3 million. We have made no repurchases since April 2015 and we have $43.7 million remaining under the repurchase program authorization as of September 30, 2022.
8.    Income Taxes
For the three months ended September 30, 2022 and September 30, 2021, we recorded an income tax expense of $20.6 million and $6.8 million, respectively, and for the nine months ended September 30, 2022 and September 30, 2021, we recorded an income tax expense of $64.6 million and an income tax benefit of $43.8 million, respectively. The change is primarily due to improved operational results over the comparison period.
Our income tax benefit or expense is based on an annual effective tax rate forecast, including estimates and assumptions that could change during the year. The application of the accounting requirements for income taxes in interim periods, after consideration of our valuation allowance on domestic losses, causes a significant variation in the typical relationship between income tax expense/benefit and pre-tax accounting income/loss as reported on the consolidated statement of operations.
As of September 30, 2022, 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 Inflation Reduction Act of 2022 was signed into law on August 16, 2022, and the CHIPS and Science Act of 2022 was signed into law on August 9, 2022. These laws implement new tax provisions, primarily a 15% corporate alternative minimum tax and a nondeductible 1% excise tax on the fair market value of stock repurchased by publicly traded corporations. As of September 30, 2022, we do not anticipate any material impact of these provisions which are effective January 1, 2023. The two acts also provide various tax credits, several of which are transferable or refundable, for the investment in or production of clean-energy effective January 1, 2023. Century will continue to evaluate potential tax benefits available under the acts as additional guidance is issued in future periods.

(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 IRBs interest rate at September 30, 2022 was 2.60%.
(2) We incur interest at a base rate plus applicable margin as defined within the agreement. The interest rate at September 30, 2022 was 6.75%.
(3) We incur interest at LIBOR plus applicable margin as defined within the agreement. The interest rate at September 30, 2022 was 6.62%.
(4) We incur interest at a base rate plus applicable margin as defined within the agreement. The interest rate at September 30, 2022 was 6.03%.

7.5% Senior Secured Notes due 2028
In April 2021, we issued $250.0 million in aggregate principal amount of 7.5% senior secured notes due April 1, 2028 (the "2028 Notes"). We received proceeds of $245.2 million, after payment of certain financing fees and related expenses. The 2028 Notes bear interest semi-annually in arrears on April 1 and October 1 of each year, which began on October 1, 2021, at a rate of 7.5% per annum in cash. The 2028 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 collateral.
As of September 30, 2022, the total estimated fair value of the 2028 Notes was $223.8 million. Although we use quoted market prices for identical debt instruments, the markets on which they trade are not considered to be active and are therefore considered Level 2 fair value measurements.
Convertible Notes due 2028
In April 2021, we completed a private offering of $86.3 million aggregate principal amount of convertible senior notes due May 1, 2028 unless earlier converted, repurchased, or redeemed (the "Convertible Notes"). The Convertible Notes were issued at a price of 100% of their aggregate principal amount. We received proceeds of $83.7 million, after payment of certain financing fees and related expenses. The Convertible Notes bear interest semi-annually in arrears on May 1 and November 1 of each year, which began on November 1, 2021, at a rate of 2.75% per annum in cash.
The initial conversion rate for the Convertible Notes is 53.3547 shares of the Company's common stock per $1,000 principal amount of Convertible Notes, which is equivalent to an initial conversion price of approximately $18.74 per share of the Company's common stock. The conversion rate and conversion price are subject to customary adjustments under certain circumstances in accordance with the terms of the indenture. As of September 30, 2022, the conversion rate remains unchanged.
The Convertible Notes are the Company’s senior unsecured obligations and rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the Convertible Notes; equal in right of payment to any of the Company’s unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of the
21

CENTURY ALUMINUM COMPANY
Condensed Notes to the Consolidated Financial Statements (continued)
(amounts in millions, except share and per share amounts)
(Unaudited)
Company’s senior secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries.
As of September 30, 2022, the if-converted value of the Convertible Notes does not exceed the outstanding principal amount.
As of September 30, 2022, the total estimated fair value of the Convertible Notes was $54.3 million. Although we use quoted market prices for identical debt instruments, the markets on which they trade are not considered to be active and are therefore considered Level 2 fair value measurements.
U.S. Revolving Credit Facility
We and certain of our direct and indirect domestic subsidiaries (the "Borrowers") have a senior secured revolving credit facility with a syndicate of lenders (as amended from time to time, the "U.S. revolving credit facility"). On June 14, 2022 we amended our U.S. revolving credit facility, increasing our borrowing capacity to $250.0 million in the aggregate, including up to $150.0 million under a letter of credit sub-facility. The U.S. revolving credit facility matures on June 14, 2027.
Any letters of credit issued and outstanding under the U.S. revolving credit facility reduce our borrowing availability on a dollar-for-dollar basis. At September 30, 2022, there were $63.5 million in outstanding borrowings and $39.9 million of outstanding letters of credit issued under our U.S. revolving credit facility. Principal payments, if any, are due upon maturity of the U.S. revolving credit facility and may be prepaid without penalty.

Iceland Revolving Credit Facility
Our wholly-owned subsidiary, Nordural Grundartangi ehf ("Grundartangi"), has entered into a $80.0 million revolving credit facility agreement with Landsbankinn hf., dated November 2013, as amended (the "Iceland revolving credit facility"). On September 28, 2022, we further amended the Iceland revolving credit facility and increased the facility amount to $100.0 million in the aggregate. Under the terms of the Iceland revolving credit facility, when Grundartangi borrows funds it will designate a repayment date, which may be any date prior to the maturity of the Iceland revolving credit facility. At September 30, 2022, there were $50.0 million in outstanding borrowings under our Iceland revolving credit facility. The Iceland revolving credit facility has a term through November 2024.

Under the Casthouse Facility, repayments of principal amounts will be made in equal quarterly installments equal to 1.739% of the principal amount, the first payment occurring in July 2024, with the remaining 60% of the principal amount to be paid no later than the termination date in December 2029. As of September 30, 2022, there were $40.0 million in outstanding borrowings under the Casthouse Facility.

Surety Bond Facility
As part of our normal business operations, we are required to provide surety bonds or issue letters of credit in certain states in which we do business as collateral for certain workers' compensation obligations. In June 2022, we entered into a surety bond facility with an insurance company to provide such bonds when applicable. As of September 30, 2022, we had issued surety bonds totaling $6.6 million. As we had previously guaranteed our workers' compensation obligations through issuance of letters of credit against our revolving credit facility, the surety bond issuance increases credit facility availability.
Iceland Term Facility
Our wholly-owned subsidiary, Grundartangi, has entered into a Term Facility Agreement with Arion Bank hf, dated September 2022, (the "Iceland Term Facility") to provide for borrowings up to €13.6 million. Repayments of principal amounts will be made in equal monthly installments, the first payment occurring in February 2023, with the remainder of the principal amount to be paid no later than the termination date in January 2024. Borrowings under the Iceland Term Facility will bear interest at a rate equal to 3.2% plus EUR EURIBOR 1 month as published at any time by the European Money Markets Institute. As of September 30, 2022, there were no outstanding borrowings under the Iceland Term Facility.
11.Commitments and Contingencies
We have pending against us or may be subject to various lawsuits, claims and proceedings related primarily to employment, commercial, stockholder, environmental, safety and health matters and are involved in other matters that may give rise to contingent liabilities. While the results of such matters and claims cannot be predicted with certainty, we believe that the ultimate outcome of any such matters and claims will not have a material adverse impact on our financial condition, results of operations or liquidity. However, because of the nature and inherent uncertainties of litigation and estimating liabilities, should the resolution or outcome of these actions be unfavorable, our business, financial condition, results of operations and liquidity could be materially and adversely affected.
In evaluating whether to accrue for losses associated with legal or environmental 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. While we regularly review the status of, and our estimates of potential liability associated with, contingencies to determine the adequacy of any associated accruals and related disclosures, the ultimate amount of loss may differ from our estimates.
Legal Contingencies
Ravenswood Retiree Medical Benefits
In November 2009, Century Aluminum of West Virginia ("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 ("USW"), the USW’s local and certain CAWV retirees, individually and as class representatives ("CAWV Retirees"), seeking a declaration of CAWV’s rights to modify/terminate retiree medical benefits. Later in November 2009, the USW 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.  On August 18, 2017, the District Court for the Southern District of West Virginia approved a settlement agreement in respect of these actions, pursuant to which, CAWV agreed to make payments into a trust for the benefit of the CAWV Retirees in the aggregate amount of $23.0 million over the course of ten years. Upon approval of the settlement, we paid $5.0 million to the aforementioned trust in September 2017 and recognized a gain of $5.5 million to arrive at the then-net present value of $12.5 million. CAWV has agreed to pay the remaining amounts under the settlement agreement in annual increments of $2.0 million for nine years. As of September 30, 2022, $2.0 million is recorded in other current liabilities and $4.7 million is recorded in other liabilities.

PBGC Settlement
In 2013, we entered into a settlement agreement with the Pension Benefit Guaranty Corporation (the "PBGC") regarding an alleged "cessation of operations" at our Ravenswood facility (the "PBGC Settlement Agreement"). Pursuant to the terms of the PBGC Settlement Agreement, we agreed to make additional contributions (above any minimum required contributions) to our defined benefit pension plans totaling approximately $17.4 million. Under certain circumstances, in periods of lower primary aluminum prices relative to our cost of operations, we were able to defer one or more of these payments, provided that we provide the PBGC with acceptable security for such deferred payments. We did not make any contributions for the three month periods ended September 30, 2022, or 2021. We historically elected to defer certain payments under the PBGC Settlement Agreement and provided the PBGC with the appropriate security. In October 2021, we amended the PBGC Settlement Agreement such that we removed the deferral mechanism and agreed to contribute approximately $2.4 million per year to our defined benefit pension plans for a total of approximately $9.6 million, over the next four years beginning on November 30, 2022 and ending on November 30, 2025, subject to acceleration if certain terms and conditions are met in such amendment.
Power Commitments and Contingencies
Hawesville
Hawesville has a power supply arrangement with Kenergy and EDF Trading North America, LLC (“EDF") which provides market-based power to the Hawesville smelter. Under this arrangement, the power companies purchase power on the open market and pass it through to Hawesville at Midcontinent Independent System Operator ("MISO") pricing plus transmission and other costs. The power supply arrangement with Kenergy has an effective term through December 2023. The arrangement with EDF to act as our market participant with MISO has an effective term through May 2023. On April 26, 2022 EDF gave notice that it would no longer serve as the MISO Market Participant for Hawesville. The notice terminated EDF’s contract, effective May 31, 2023, to purchase power from MISO for resale to Kenergy, which then resells the power to Hawesville. Century is in discussions with other companies, currently authorized as MISO Market Participants, to replace EDF and expects to have a replacement Market Participant in place prior to the expiration of the contract with EDF.

In connection with the temporary curtailment of production at Hawesville, energy use at the smelter has been significantly reduced. However, such reduction in energy use does not reduce Hawesville’s capacity payment obligation to MISO which extends through May 2023.
Sebree
Sebree has a power supply arrangement with Kenergy and EDF which provides market-based power to the Sebree smelter. Similar to the arrangement at Hawesville, the power companies purchase power on the open market and pass it through to Sebree at MISO pricing plus transmission and other costs. The power supply arrangement with Kenergy has an effective term through December 2023. The arrangement with EDF to act as our market participant with MISO has an effective term through May 2023. On April 26, 2022 EDF gave notice that it would no longer serve as the MISO Market Participant for Sebree. The notice terminated EDF’s contract, effective May 31, 2023, to purchase power from MISO for resale to Kenergy, which then resells the power to Sebree. Century is in discussions with other companies, currently authorized as MISO Market Participants, to replace EDF and expects to have a replacement Market Participant in place prior to the expiration of the contract with EDF.
Mt. Holly
Century Aluminum of South Carolina, Inc. has a power supply agreement with Santee Cooper that has an effective term from April 1, 2021 through December 2023. Under this power supply agreement, 100% of Mt. Holly’s electrical power requirements are supplied from Santee Cooper’s generation at cost of service based rates. The contract provides sufficient energy to allow Mt. Holly to produce at 75% of full production capacity.

Grundartangi
Grundartangi has power purchase agreements for approximately 545 MW with HS Orka hf ("HS"), Landsvirkjun and Orkuveita Reykjavikur ("OR") to provide power to its Grundartangi smelter. These power purchase agreements expire on various dates from 2026 through 2036 (subject to extension). The power purchase agreements with HS and OR provide power at LME-based variable rates for the duration of these agreements. In July 2021, Grundartangi reached an agreement with Landsvirkjun for an extension of its existing 161 MW power contract that would have expired in December 2023. Under the terms of the extension, Landsvirkjun will continue to supply power to Grundartangi from January 1, 2024 through December 31, 2026 and will increase the existing contract from 161 MW to 182 MW over time to provide the necessary flexibility to support the most recent capacity creep requirements and future growth opportunities for value-added products at the Grundartangi plant, including the Grundartangi casthouse project. In September 2022, this agreement was amended to provide for 42 MW at a fixed price and 119 MW at rates linked to Nord Pool plus transmission through 2023 and beginning January 1, 2024 through December 31, 2026, this agreement allows for fixed rates plus a small variable rate portion of the full 182 MW. Grundartangi also has a 25 MW power purchase agreement with Landsvirkjun at LME-based variable rates.
Other Commitments and Contingencies
Labor Commitments
The bargaining unit employees at our Grundartangi, Vlissingen, Hawesville and Sebree facilities are represented by labor unions, representing approximately 58% of our total workforce. 
Approximately 87% of Grundartangi’s work force is represented by five labor unions, governed by a labor agreement that establishes wages and work rules for covered employees. This agreement is effective through December 31, 2024.
100% of Vlissingen's work force is represented by the Federation for the Metal and Electrical Industry ("FME"), a Netherlands' employers' organization for companies in the metal, electronics, electrical engineering and plastic sectors. The FME negotiates working conditions with trade unions on behalf of its members, which, when agreed upon, are then applicable to all employees of Vlissingen. The current labor agreement is effective through November 30, 2022. On September 22, 2022, a new labor agreement was reached which will go into effect on December 1, 2022, and expire on May 31, 2024.

Approximately 42% of our U.S. based work force is represented by USW through separately negotiated labor agreements for each facility. The labor agreement for Hawesville employees is effective through April 1, 2026. Upon announcement of the temporary curtailment, Hawesville and the USW local union entered into effects bargaining. An agreement was reached on July 19, 2022, covering the curtailment period. Century Sebree's labor agreement with the USW for its employees is effective through October 28, 2023. Mt. Holly employees are not represented by a labor union.
Contingent obligations
We have a contingent obligation in connection with the "unwind" of a contractual arrangement between Century Aluminum of Kentucky ("CAKY"), Big Rivers Electric Corporation and a third party and the execution in July 2009 of a long-term cost-based power contract with Kenergy, a member of a cooperative of Big Rivers. This contingent obligation consists of the aggregate payments made to Big Rivers by the third party on CAKY’s behalf in excess of the agreed upon base amount under the long-term cost-based power contract with Kenergy. As of September 30, 2022, the principal and accrued interest for the contingent obligation was $29.1 million, which was fully offset by a derivative asset. We may be required to make installment payments for the contingent obligation in the future. These payments are contingent based on the LME price of primary aluminum and the level of Hawesville’s operations. As of September 30, 2022, the LME forward market prices do not exceed the threshold for payment. In addition, based on the current level of Hawesville's operations, including the temporary curtailment, we believe that we will not be required to make payments on the contingent obligation during the term of the agreement, which expires in 2028. There can be no assurance that circumstances will not change thus accelerating the timing of such payments.

We measure our obligations under our defined benefit plan and other post retirement benefits annually or more frequently at interim periods when a significant event occurs. ASC 715, Compensation-Retirement Benefits, defines a curtailment as an event that significantly reduces the expected years of future service of present employees or eliminates defined benefits for some or all of a significant number of employees. In the third quarter, we took actions to re-measure certain other postretirement benefits triggered by the Hawesville smelter curtailment, leading to a non-cash OPEB curtailment gain, net totaling $8.0 million for the three and nine months ended September 30, 2022.
14. Derivatives
As of September 30, 2022, we had an open position of 148,416 tonnes related to LME forward financial sales contracts to fix the forward LME aluminum price. These contracts are expected to settle monthly through December 2024. We also had an open position of 48,750 tonnes related to MWP forward financial sales contracts to fix the forward MWP price. These contracts are expected to settle monthly through December 2022. We have also entered into financial contracts with various counterparties to offset fixed price sales arrangements with certain of our customers ("fixed for floating swaps") to remain exposed to the LME and MWP aluminum prices. As of September 30, 2022, we had 1,014 tonnes related to fixed for floating swaps that will settle monthly through February 2023.
We have entered into financial contracts to hedge a portion of Grundartangi's exposure to the Nord Pool power market (“Nord Pool power price swaps”). All of our Nord Pool power price swaps will cash settle monthly through December 2023. Because the Nord Pool power price swaps are settled in Euros, we have entered into financial contracts to hedge the risk of fluctuations associated with the Euro ("FX swaps"). As of September 30, 2022, we had an open position related to the FX swaps of €37.9 million that will settle monthly through December 2023.
During the third quarter of 2022, we entered certain floating Nord Pool financial contracts to unwind a portion of our fixed contract position as a result of the recent power agreement amendment, making us predominantly hedged against Nord Pool power price fluctuations during 2023. As of September 30, 2022, we had an open net position of 1,239,497 MWh related to the Nord Pool power price swaps. The pricing relationship between the fixed and floating Nord Pool contracts created a realized gain of $16.0 million, which we recognized for the three and nine months ended September 30, 2022.

We have entered into financial contracts to fix a portion of our exposure to the Indiana Hub power market at our Kentucky plants ("Indiana Hub power price swaps"). As of September 30, 2022, we had an open position of 219,360 MWh. The Indiana Hub power price swaps are expected to settle monthly through December 2023.
We have entered into forward contracts to hedge the risk of fluctuations associated with the Icelandic Krona (ISK) and Euro for contracts related to the construction of the Grundartangi casthouse denominated in these currencies ("casthouse currency hedges"). As of September 30, 2022, we had an open position related to the ISK casthouse swaps of $52.0 million that will settle monthly through July 2023. As of September 30, 2022, we had an open position related to the Euro casthouse swaps of $13.8 million that will settle monthly through February 2024.

Our agreements with derivative counterparties contain certain provisions requiring collateral to be posted in the event the market value of our position exceeds the margin threshold limit of our master agreement with the counterparty. As of September 30, 2022 and December 31, 2021, the Company had recorded restricted cash of $0.0 million and $8.6 million, respectively, as collateral related to open derivative contracts under the master arrangements with our counterparties.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
This Management’s Discussion and Analysis (“MD&A”) provides information that management believes is relevant to an assessment and understanding of the consolidated financial condition and results of operations of Century Aluminum Company and should be read in conjunction with the accompanying consolidated financial statements and related notes thereto. This MD&A contains “forward-looking statements” - see “Forward-Looking Statements” above.
Overview
We are a global producer of primary aluminum with aluminum reduction facilities, or "smelters," in the United States and Iceland. The key determinants of our results of operations and cash flows from operations are as follows:
the price of primary aluminum, which is based on the London Metal Exchange ("LME") and other exchanges, plus any regional premiums and value-added product premiums;
the cost of goods sold, the principal components of which are electrical power, alumina, carbon products and labor, which in aggregate represent more than 75% of our cost of goods sold; and
our production volume and product mix.
Recent Developments
Hawesville temporary curtailment
On June 22, 2022, we announced that we would temporarily idle all of our production capacity at our Hawesville smelter, as a direct result of historically high energy costs and declining LME prices. As part of this action, we issued a notice to most of the employees at the facility pursuant to the Worker Adjustment and Retraining Notification (“WARN”) Act regarding our intentions to temporarily curtail Hawesville plant operations by no later than August 20, 2022. We have since fully curtailed all of our production at the facility and expect to continue to maintain the plant with the intention of restarting operations when market conditions permit, including energy prices returning to more normalized levels and aluminum prices maintaining levels that can support the on-going costs and capital expenditures necessary to restart and operate the plant.

As the curtailment represents a significant adverse change in the extent and manner in which the Hawesville smelter will be used, we accordingly evaluated the Hawesville asset group for recoverability. As the carrying value of the Hawesville asset group was determined to not be recoverable based on the estimated undiscounted cash flows expected to be generated over the life of the asset group, an impairment charge of $159.4 million was recognized to write down the asset group to its estimated fair value. We recognized $12.6 million of expense through the third quarter related to wages and severance triggered by our issuance of the WARN notice and excess capacity charges, partially offset by final plant idling activities. We also recognized a non-cash OPEB curtailment gain, net totaling $8.0 million for the three and nine months ended September 30, 2022. See Note 13. Components of net periodic benefit cost to the consolidated financial statements included herein for additional information.
Pricing of aluminum
The overall price of primary aluminum consists of three components: (i) the base commodity price, which is based on quoted prices on the LME and other exchanges; plus (ii) any regional premium (e.g., the Midwest premium for metal sold in the United States ("MWP") and the European Duty Paid premium for metal sold into Europe ("EDPP")); plus (iii) any value-added product premium. Each of these price components has its own drivers and variability.
The aluminum price is influenced by a number of factors, including global supply-demand balance, inventory levels, speculative activities by market participants, production activities by competitors and political and economic conditions, as well as production costs in major production regions. These factors can be highly speculative and difficult to predict which can lead to significant volatility in the aluminum price. Increases or decreases in primary aluminum prices result in increases and decreases in our revenues (assuming all other factors are unchanged). From time to time, we may seek to manage our exposure to fluctuations in the LME price of primary aluminum and/or associated regional premiums through financial instruments designed to protect our downside price risk exposure. Information regarding financial contracts is included in Note 14. Derivatives and risks associated with such financial contracts are disclosed specifically in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

We have seen declines in the pricing of aluminum through the third quarter of 2022, when compared to the aluminum prices that were generally increasing throughout 2021 and during the first quarter of 2022. The quarterly average LME price for primary aluminum was $3,267 per tonne in the first quarter of 2022, decreasing to $2,882 per tonne for the second quarter of 2022 and then to $2,354 in the third quarter of 2022 compared to annual average of $2,475 per tonne in 2021 and $1,702 per
33

tonne in 2020. The quarterly average MWP price was $583 per tonne for the third quarter of 2022, compared to $805 per tonne for the second quarter of 2022, $794 per tonne for the first quarter of 2022, and to annual average of $581 per tonne in 2021 and $267 per tonne in 2020. The quarterly average EDPP price was $501 per tonne for the third quarter of 2022, compared to $604 per tonne for the second quarter of 2022, $489 per tonne for the first quarter of 2022 and to annual average of $272 per tonne in 2021 and $126 per tonne in 2020.
Results of Operations
The following discussion for the three and nine months ended September 30, 2022 reflects no change in production capacities, other than the curtailment of the Hawesville smelter, at our operating facilities.
Our net sales are impacted primarily by the LME price for aluminum, regional and value-added premiums, and the volume and product mix of aluminum we ship during the period. In general, our results reflect the LME and regional premium pricing on an approximately one to three month lag basis reflecting contractual terms with our customers.

Electrical power, alumina, carbon products and labor are the principal components of our cost of goods sold. Power costs can be volatile as a result of a number of factors beyond our control. See “Item 1A. Risk Factors - Increases in energy costs adversely affect our business, financial position, results of operations and liquidity” in our Annual Report on Form 10-K for the year ended December 31, 2021. Power costs at our Kentucky plants are impacted by capacity demand charges, which are determined based on available power generating capacity in MISO, from which we purchase energy. The price of such capacity is set by auction in April. Our expected capacity demand costs for power are expected to be approximately $11.5 million per quarter after June 1, 2022 (notwithstanding the curtailment at Hawesville), in addition to the market price of power used.

The recent increase in energy costs has adversely affected our business, and is expected to continue to adversely affect our business over the near term until power prices return to more normalized levels and/or LME prices improve. Increased domestic energy costs have resulted in the curtailment of our Hawesville facility as described above. In Europe, increased energy prices affect both our Grundartangi operations (a portion of our power is linked to the Nord Pool power market) and our Vlissingen facility in the Netherlands, which utilizes natural gas to produce anodes used in our Grundartangi operations. The energy market in Europe is materially dependent upon imported natural gas from Russia, and the threat of Russia further reducing or terminating natural gas supply to Europe creates uncertainty with respect to the price and availability of natural gas, which could adversely affect operations at Vlissingen, and in turn operations at Grundartangi, if we are not able to source an alternative supply of anodes.
In general, our results reflect the market cost of alumina on an approximately three-month lag reflecting the terms of our alumina contracts and inventory levels.

Net sales$637.2 $856.6 $2,247.4 $1,553.4 

Net sales (excluding scrap aluminum, purchased aluminum and alumina sales) decreased by $234.0 million for the three months ended September 30, 2022, compared to the three months ended June 30, 2022, primarily driven by unfavorable LME and premium price realizations of $81.6 million and unfavorable volume of $152.2 million primarily attributable to the full curtailment of our Hawesville smelter.

Net sales (excluding scrap aluminum, purchased aluminum and alumina sales) increased by $676.2 million for the nine months ended September 30, 2022, compared to the nine months ended September 30, 2021, primarily driven by favorable LME and premium price realizations of $569.3 million and favorable volume and sales mix of $106.9 million driven by the restart at our Mt. Holly facility and higher value-added product premiums, partially offset by full the curtailment of our Hawesville smelter.

Gross profit decreased by $58.9 million for the three months ended September 30, 2022, compared to the three months ended June 30, 2022, primarily driven by unfavorable metal price realization of $81.6 million, unfavorable volume mix of $44.9 million primarily attributable to the full curtailment of our Hawesville smelter, and unfavorable power price realization of $29.1 million, partially offset by decreased operating costs of $57.6 million as a result of the full curtailment of our Hawesville smelter and other cost savings from our remaining operating smelters and favorable raw material price realization of $30.3 million.

Gross profit increased by $11.3 million for the nine months ended September 30, 2022 compared to the nine months ended September 30, 2021, primarily driven by favorable metal price realization of $569.3 million and favorable volume and sales mix of $70.2 million driven by the restart at our Mt. Holly facility and higher value-added product premiums, net of the $27.4 million impact of the full curtailment of our Hawesville smelter. The change is partially offset by unfavorable raw material price realization of $298.7 million, unfavorable power price realization of $281.8 million and higher operating costs of $48.0 million.

Asset impairment charge$— $159.4 $159.4 $— 

An asset impairment charge of $159.4 million was recognized in the period ended September 30, 2022 as a result of the temporary curtailment of the Hawesville facility, announced during June 2022. As the curtailment represents a significant adverse change in the extent and manner in which Hawesville will be used, we accordingly evaluated the Hawesville asset group for recoverability which resulted in the recognized impairment charge of $159.4 million.

Liquidity and Capital Resources
Liquidity
Our principal sources of liquidity are available cash and cash flows from operations. We also have access to our existing U.S. and Iceland revolving credit facilities (collectively, the "revolving credit facilities") and have raised capital in the past through public equity and debt markets. We regularly explore various other financing alternatives. Our principal uses of cash include the funding of operating costs (including post-retirement benefits), debt service requirements, capital expenditures, investments in our growth activities and in related businesses, working capital and other general corporate requirements.
We believe that cash provided from operations and financing activities will be adequate to cover our operations and business needs over the next twelve months. As of September 30, 2022, we had cash and cash equivalents of approximately $64.8 million and unused availability under our revolving credit facilities of $136.9 million and Iceland Term Facility of €13.6 million, resulting in a total liquidity position of approximately $215.1 million.
Available Cash
Our available cash and cash equivalents balance at September 30, 2022 was $64.8 million compared to $29.0 million at December 31, 2021.
Sources and Uses of Cash
Our statements of cash flows are summarized below:
Nine Months Ended September 30,
20222021
(in millions)
Net cash provided by (used in) operating activities$57.2 $(12.1)
Net cash used in investing activities(70.1)(45.7)
Net cash provided by financing activities38.2 42.4 
Change in cash, cash equivalents and restricted cash$25.3 $(15.4)


The change from net cash used in operating activities during the nine months ended September 30, 2021 to net cash provided by operating activities during the nine months ended September 30, 2022 was primarily driven by net income during the first three quarters, partially offset by changes in working capital. The changes in working capital are primarily attributable to timing of receivable collections, timing of raw material receipts, and pricing increases.

The increase in net cash used in investing activities was primarily due to higher spending on capital projects during the nine months ended September 30, 2022, driven by capital investments in the Mt. Holly restart project and the Grundartangi casthouse project.

The change in net cash provided by financing activities was primarily due to borrowings under the Grundartangi casthouse debt facility in 2022 as compared to net borrowing on our revolving credit facilities in 2021.
Availability Under Our Credit Facilities
The U.S. revolving credit facility, dated May 2018 (as amended, the "U.S. revolving credit facility"), previously provided for borrowings of up to $220.0 million, including up to $110.0 million under a letter of credit sub-facility. In June 2022, we entered into a Fourth Amendment to our existing $220.0 million U.S. revolving credit facility, increasing the maximum capacity from $220.0 million to $250.0 million, including up to $150.0 million under a letter of credit sub-facility. The U.S. revolving credit facility matures in June 2027. Any letters of credit issued and outstanding under the U.S. revolving credit facility reduce our borrowing availability on a dollar-for-dollar basis.
We have also entered into, through our wholly-owned subsidiary Nordural Grundartangi ehf ("Grundartangi"), a $50.0 million revolving credit facility, dated November 2013, as amended (the "Iceland revolving credit facility"). On February 4, 2022, we amended the Iceland revolving credit facility and increased the facility amount to $80.0 million in the aggregate. On
37

September 28, 2022, we further amended the Iceland revolving credit facility and increased the facility amount to $100.0 million in the aggregate. The Iceland revolving credit facility matures in November 2024.
The availability of funds under our credit facilities is limited by a specified borrowing base consisting of certain accounts receivable, inventory and qualified cash deposits which meet the lenders' eligibility criteria. Increases in the price of aluminum and/or restarts of previously curtailed operations, for example, increase our borrowing base by increasing our accounts receivable and inventory balances; decreases in the price of aluminum and/or curtailments of production capacity would decrease our borrowing base by reducing our accounts receivable and inventory balances. As of September 30, 2022, our U.S. revolving credit facility had a borrowing base of $190.3 million, $63.5 million in borrowings and $39.9 million in letters of credit outstanding. Of the outstanding letters of credit, $26.6 million are related to our power commitments and $13.3 million are primarily for the purpose of securing certain debt and workers’ compensation commitments. As of September 30, 2022, our Iceland revolving credit facility had a borrowing base of $100.0 million and $50.0 million in outstanding borrowings.
As of September 30, 2022, our credit facilities had $136.9 million of net availability after consideration of our outstanding borrowings and letters of credit. We may borrow and make repayments under our credit facilities in the ordinary course based on a number of factors, including the timing of payments from our customers and payments to our suppliers.
Our credit facilities contain customary covenants, including restrictions on mergers and acquisitions, indebtedness, affiliate transactions, liens, dividends and distributions, dispositions of collateral, investments and prepayments of indebtedness, including in the U.S. revolving credit facility, a springing financial covenant that requires us to maintain a fixed charge coverage ratio of at least 1.0 to 1.0 as of any date of determination on which availability under the U.S. revolving credit facility is less than or equal to $25.0 million, or 10% of the borrowing base, but not less than $17.85 million. We intend to maintain availability to comply with these levels any time we would not meet the ratio, which could limit our ability to access the full amount of our availability under our U.S revolving credit facility. Our Iceland revolving credit facility contains a covenant that requires Grundartangi to maintain a minimum equity ratio. As of September 30, 2022, we were in compliance with all such covenants or maintained availability above such covenant triggers.
Grundartangi Casthouse Facility
On November 2, 2021, Grundartangi entered into an eight-year Term Facility Agreement with Arion Bank hf, to provide for borrowings up to $130.0 million in connection with the casthouse project at Grundartangi (the "Casthouse Facility"). Under the Casthouse Facility, repayments of principal amounts will be made in equal quarterly installments equal to 1.739% of the principal amount, the first payment occurring in July 2024, with the remaining 60% of the principal amount to be paid no later than the termination date. The Casthouse Facility will mature in December 2029. The Casthouse Facility bears interest at a rate equal to USD LIBOR 3 month plus an applicable margin. As of September 30, 2022 there were $40.0 million in borrowings outstanding under the Casthouse Facility.
The Casthouse Facility also contains customary covenants, including restrictions on mergers and acquisitions, indebtedness, preservation of assets, and dispositions of assets and contains a covenant that requires Grundartangi to maintain a minimum equity ratio. As of September 30, 2022, we were in compliance with all such covenants.
Senior Notes and Convertible Senior Notes
In April 2021, we issued $250.0 million principal of senior secured notes that will mature on April 1, 2028 (the "2028 Notes"), unless earlier refinanced in accordance with their terms. Interest on the 2028 Notes is payable semi-annually on April 1 and October 1 of each year, at a rate of 7.5% per year. The indenture governing the 2028 Notes contains customary covenants which may limit our ability, and the ability of certain of our subsidiaries, to: (i) incur additional debt; (ii) incur additional 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.
In April 2021, we issued $86.3 million in aggregate principal amount of Convertible Notes (the "Convertible Notes"), that will mature on May 1, 2028, unless earlier converted, repurchased or redeemed. The principal included the full exercise of the option by the initial purchasers of the Convertible Notes to purchase $11.3 million of additional principal amount. The Convertible Notes bear interest semi-annually in arrears on May 1 and November 1 of each year, at a rate of 2.75% per annum in cash.
Iceland Term Facility
Our wholly-owned subsidiary, Grundartangi, has entered into a Term Facility Agreement with Arion Bank hf, dated September 2022, (the "Iceland Term Facility") to provide for borrowings up to €13.6 million. Under the Iceland Term Facility,
38

repayments of principal amounts will be made in equal monthly installments, the first payment occurring in February 2023, with the remainder of the principal amount to be paid no later than the termination date in January 2024. Borrowings under the Iceland Term Facility will bear interest at a rate equal to 3.2% plus EUR EURIBOR 1 month as published at any time by the European Money Markets Institute. As of September 30, 2022, there were no outstanding borrowings under the Iceland Term Facility.
Supplemental Guarantor Financial Information
The Company has filed a Registration Statement on Form S-3 (the "Universal Shelf Registration Statement") with the SEC pursuant to which the Company may, from time to time, offer an indeterminate amount of securities, which may include securities that are guaranteed by certain of the Company's subsidiaries. As of September 30, 2022, we have not issued any debt securities pursuant to the Universal Shelf Registration Statement. However, any securities that we may issue in the future may limit our ability, and the ability of certain of our subsidiaries, to pay dividends or make distributions in respect of capital stock.
"Guarantor Subsidiaries" refers to all of our material domestic subsidiaries except for Nordural US LLC, Century Aluminum Development LLC and Century Aluminum of West Virginia, Inc. The Guarantor Subsidiaries are 100% owned by Century. All guarantees will be full and unconditional; all guarantees will be joint and several. Our foreign subsidiaries, together with Nordural US LLC, Century Aluminum Development LLC and Century Aluminum of West Virginia, Inc., are collectively referred to as the "Non-Guarantor Subsidiaries". We allocate corporate expenses or income to our subsidiaries and charge interest on certain intercompany balances.
The following summarized financial information of both the Company and the Guarantor Subsidiaries ("Guarantors") is presented on a combined basis. Intercompany balances and transactions between the Company and the Guarantors have been eliminated and the summarized financial information does not reflect investments of the Company or the Guarantors in the Non-Guarantor Subsidiaries ("Non-Guarantors"). The Company’s or Guarantors’ amounts due from, amounts due to, and transactions with the Non-Guarantors are disclosed below:

As of September 30, 2022 and December 31, 2021, an intercompany receivable due to the Company and Guarantors from the Non-Guarantors totaled $6.4 million and $15.1 million, respectively, and an intercompany non-current loan due to the Company from the Non-Guarantors totaled $498.6 million and $544.2 million, respectively.
Contingent Commitments
We have a contingent obligation in connection with the "unwind" of a contractual arrangement between Century Aluminum of Kentucky ("CAKY"), Big Rivers Electric Corporation and a third party and the execution in July 2009 of a long-term cost-based power contract with Kenergy, a member of a cooperative of Big Rivers. This contingent obligation consists of the aggregate payments made to Big Rivers by the third party on CAKY’s behalf in excess of the agreed upon base amount under the long-term cost-based power contract with Kenergy.  As of September 30, 2022, the principal and accrued interest for the contingent obligation was $29.1 million, which was fully offset by a derivative asset. We may be required to make installment payments for the contingent obligation in the future. These payments are contingent based on the LME price of primary aluminum and the level of Hawesville’s operations. As of September 30, 2022, based on the LME forward market prices and our expected level of Hawesville operations, we believe that we will not be required to make payments on the
39

contingent obligation during the term of the agreement, which expires in 2028. There can be no assurance that circumstances will not change thus accelerating the timing of such payments.
Employee Benefit Plan Contributions
In 2013, we entered into a settlement agreement with the Pension Benefit Guaranty Corporation (the "PBGC") regarding an alleged "cessation of operations" at our Ravenswood facility (the "PBGC Settlement Agreement"). Pursuant to the terms of the PBGC Settlement Agreement, we agreed to make additional contributions (above any minimum required contributions) to our defined benefit pension plans totaling approximately $17.4 million. Under certain circumstances, in periods of lower primary aluminum prices relative to our cost of operations, we were able to defer one or more of these payments, provided that we provide the PBGC with acceptable security for such deferred payments. We did not make any contributions for the three months ended September 30, 2022, and 2021. We historically elected to defer certain payments under the PBGC Settlement Agreement and provided the PBGC with the appropriate security. In October 2021, we amended the PBGC Settlement Agreement such that we removed the deferral mechanism and agreed to contribute approximately $2.4 million per year to our defined benefit pension plans for a total of approximately $9.6 million, over the next four years beginning on November 30, 2022 and ending on November 30, 2025, subject to acceleration if certain terms and conditions are met in such amendment.
Section 232 Aluminum Tariff

On March 23, 2018, the U.S. implemented a 10% tariff on imported primary aluminum products into the U.S. These tariffs are intended to protect U.S. national security and incentivize the restart of primary aluminum production in the U.S., reducing reliance on imports and ensuring that domestic producers, like Century, can supply all the aluminum necessary for critical industries and national defense.  In addition to primary aluminum products, the tariffs also cover certain other semi-finished products. All imports that directly compete with our products are covered by the tariff, with the exception of imports from Australia, Canada and Mexico. Additionally, primary aluminum imports from Argentina are allowed up to an annual quota limit of 169,000 metric tonnes, the first 18,000 metric tonnes of imports from the European Union and the first 900 metric tonnes of imports from the United Kingdom are also allowed duty free. Imports that receive a product exclusion from the Department of Commerce may also enter the US duty free. In July 2022, the International Trade Commission (ITC) initiated a review of the Section 301 and 232 duties as required by law every four years. The process will conclude no later than March 15, 2023.
Other Items

During 2021, we initiated efforts to restart the curtailed capacity at our Mt. Holly facility. The project was completed during the second quarter of 2022, resulting in total production of 75% of Mt. Holly’s full capacity.

During 2021, we announced plans for construction of a new billet casthouse at Grundartangi. The Grundartangi casthouse project began in late 2021 and is expected to continue through the second half of 2023. The Grundartangi casthouse project will be fully funded through the Casthouse Facility. The project is progressing and is expected to be completed on-time, subject to market conditions.
In 2011, our Board of Directors approved a $60.0 million common stock repurchase program and subsequently increased this program by $70.0 million in the first quarter of 2015. Under the program, Century is authorized to repurchase up to $130.0 million of our outstanding shares of common stock, from time to time, on the open market at prevailing market prices, in block trades or otherwise. The timing and amount of any shares repurchased will be determined by our management based on its evaluation of market conditions, the trading price of our common stock and other factors. We made no repurchases during the years ended 2019, 2020, and 2021. As of September 30, 2022, we had $43.7 million remaining under the repurchase program authorization. The repurchase program may be expanded, suspended or discontinued by our Board, in its sole discretion, at any time.

In November 2009, Century Aluminum of West Virginia, Inc. ("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 ("USW"), the USW’s local and certain CAWV retirees, individually and as class representatives ("CAWV Retirees"), seeking a declaration of CAWV’s rights to modify/terminate retiree medical benefits.  Later in November 2009, the USW 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. On August 18, 2017, the District Court for the Southern District of West Virginia approved a settlement agreement in respect of these actions, pursuant to which, CAWV agreed to make payments into a trust for the benefit of the CAWV Retirees in the aggregate amount of $23.0 million over the course of ten years. Upon approval of the settlement, we paid $5.0 million to the aforementioned trust in September 2017 and agreed to pay the remaining amounts under the settlement agreement in annual increments of $2.0 million for nine years. At September 30, 2022, we had $2.0 million in other current liabilities and $4.7 million in other liabilities related to this agreement.

We are a defendant in several actions relating to various aspects of our business. While it is impossible to predict the ultimate disposition of any litigation, we do not believe that any of these lawsuits, either individually or in the aggregate, will have a material adverse effect on our financial condition, results of operations or liquidity. See Note 11. Commitments and Contingencies to the consolidated financial statements included herein for additional information.
Capital Resources
We intend to finance our future capital expenditures from available cash, cash flows from operations and if necessary, borrowing under our existing revolving credit facilities. For major investment projects we would likely seek financing from various capital and loan markets and may potentially pursue the formation of strategic alliances. We may be unable, however, to issue additional debt or equity securities, or enter into other financing arrangements on attractive terms, or at all, due to a number of factors including a lack of demand, unfavorable pricing, poor economic conditions, unfavorable interest rates, or our financial condition or credit rating at the time. Future uncertainty in the U.S. and international markets and economies may adversely affect our liquidity, our ability to access the debt or capital markets and our financial condition.
Capital expenditures incurred for the nine months ended September 30, 2022 were $14.6 million, excluding expenditures of $16.2 million associated with the restart project at Mt. Holly and $28.5 million associated with the Grundartangi casthouse project. We estimate our total capital spending in 2022, excluding the Mt. Holly restart project and the Grundartangi casthouse project, will be approximately $25.0 to $30.0 million related to our ongoing investment and sustainability projects at our plants.

Item 3. Quantitative and Qualitative Disclosures about Market Risk
Commodity Price and Raw Material Costs Sensitivities
Aluminum is an internationally traded commodity, and its price is effectively determined on the LME plus any regional premium (e.g. the Midwest premium for aluminum sold in the United States and the European Duty Paid premium for metal sold into Europe) and any product premiums. From time to time, we may manage our exposure to fluctuations in the LME price of primary aluminum and/or associated regional premiums through financial instruments designed to protect our downside price risk exposure. From time to time, we also enter into financial contracts to offset fixed price sales arrangements with certain of our customers (the "fixed for floating swaps").   
We are also exposed to price risk for alumina which is one of the largest components of our cost of goods sold. Certain of the alumina we purchase is priced based on a published alumina index. As a result, our cost structure is exposed to market fluctuations and price volatility. Because we sell our products based principally on the LME price for primary aluminum, regional premiums and value-added product premiums, we are not able to directly pass on increased production costs to our customers. From time to time, we may manage our exposure to fluctuations in our alumina costs by purchasing certain of our alumina requirements under supply contracts with prices tied to the same indices as our aluminum sales contracts (the LME price of primary aluminum).
Market-Based Power Price Sensitivity
Market-Based Electrical Power Agreements
Hawesville and Sebree have market-based electrical power agreements pursuant to which EDF and Kenergy purchase electrical power on the open market and pass it through at MISO energy pricing, plus transmission and other costs incurred by them. See Note 11. Commitments and Contingencies to the consolidated financial statements included herein for additional information about these market-based power agreements.
Power is supplied to Grundartangi from hydroelectric and geothermal sources under long-term power purchase agreements. These power purchase agreements, which will expire on various dates from 2026 through 2036 (subject to extension), currently primarily provide power at LME-based variable rates. At this time, the price of approximately 20-25% of Grundartangi's power requirements is linked to the market price for power in the Nord Pool power market.
From time to time, we may manage our exposure to fluctuations in the market price of power through financial instruments designed to protect our downside risk exposure. 
Electrical Power Price Sensitivity
Power represents one of our largest operating costs, so changes in the price and/or availability of market power could significantly impact the profitability and viability of our operations. Given our market-based power supply agreements, we have electrical power price risk for our operations, whether due to fluctuations in the price of power (whether it be the cost of energy itself, generation capacity costs, or transmission costs) available on the MISO or Nord Pool power markets or the price of natural gas. Transmission line outages, reduction in power production by power suppliers, problems with grid stability or limitations on energy import capability could also increase power prices, disrupt production through pot instability or force a curtailment of all or part of the production at these facilities. In addition, indirect factors that lead to power cost increases, such as any disruptions in supply of natural gas or coal, increasing prices for natural gas or coal, fluctuations in or extremes in weather patterns or new or more stringent environmental regulations may severely impact our financial condition, results of operations and liquidity.

Annual cost impact of an increase or decrease of $1 per MWh (in millions)$4.2 $3.4 $3.5 $4.7 $15.8 
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"), the Euro, the Chinese renminbi and other currencies.  Grundartangi’s labor costs, costs associated with the casthouse project, part of its maintenance costs and other local services are denominated in ISK and a portion of its anode costs are denominated in Euros and Chinese renminbi.  We also have deposits denominated in ISK in Icelandic banks and our estimated payments of Icelandic income taxes and any associated refunds are denominated in ISK. Further, Vlissingen's labor costs, maintenance costs and other local services are denominated in Euros and our existing Nord Pool power price swaps described above are settled in Euros. As a result, an increase or decrease in the value of those currencies relative to the U.S. dollar would affect Grundartangi’s and Vlissingen's operating margins.
We may manage our foreign currency exposure by entering into foreign currency forward contracts or option contracts for forecasted transactions and projected cash flows for foreign currencies in future periods.  For example, we have entered into the FX swaps to hedge the risk of fluctuations associated with the Euro in connection with our Nord Pool power price swaps.
Natural Economic Hedges
Any analysis of our exposure to the commodity price of aluminum should consider the impact of natural hedges provided by certain contracts that contain pricing indexed to the LME price for primary aluminum. Certain of our alumina contracts and a substantial portion of Grundartangi’s electrical power requirements are indexed to the LME price for primary aluminum and provide a natural hedge for a portion of our production.
Risk Management
Any metals, power, natural gas and foreign currency risk management activities are subject to the control and direction of senior management within guidelines established by Century’s Board of Directors. These activities are regularly reported to Century’s Board of Directors.

Item 5. Other Information
Disclosure pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act

Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 (“ITRA”), effective August 10, 2012, added a new subsection (r) to Section 13 of the Exchange Act, which requires issuers that file periodic reports with the SEC to disclose in their annual and quarterly reports whether, during the reporting period, they or any of their “affiliates” (as defined in Rule 12b-2 under the Exchange Act) have knowingly engaged in specified activities or transactions relating to Iran, including activities not prohibited by U.S. law and conducted outside the U.S. by non- U.S. affiliates in compliance with applicable laws. Issuers must also file a notice with the SEC if any disclosable activity under ITRA has been included in an annual or quarterly report.

Because the SEC defines the term “affiliate” broadly, our largest stockholder may be considered an affiliate of the Company despite the fact that the Company has no control over its largest stockholder’s actions or the actions of its affiliates. As such, pursuant to Section 13(r)(1)(D)(iii) of the Exchange Act, the Company hereby discloses the following information provided by our largest stockholder regarding transactions or dealings with entities controlled by the Government of Iran (“the GOI”):

During the quarter ended September 30, 2022, non-U.S. affiliates of the largest stockholder of the Company (“the non-U.S. Stockholder Affiliates”) entered into sales contracts for agricultural products with, or for delivery to or from Iranian entities wholly or majority owned by the GOI. The non-U.S. Stockholder Affiliates performed their obligations under the contracts in compliance with applicable sanction laws and, where required, with the necessary prior approvals by the relevant governmental authorities.
 
The gross revenue of the non-U.S. Stockholder Affiliates related to the contracts did not exceed the value of USD $492 million for the quarter ended September 30, 2022.

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 contracts would not exceed a small fraction of the gross revenue from such contracts. It is not possible to determine accurately the precise net profit attributable to such contracts.

The contracts disclosed above do not violate applicable sanctions laws administered by the U.S. Department of the Treasury, Office of Foreign Assets Control, and are not the subject of any enforcement action under Iran sanction laws.
The non-U.S. Stockholder Affiliates expect to continue to engage in similar activities in the future in compliance with applicable economic sanctions and in conformity with U.S. secondary sanctions.

The Company and its global subsidiaries had no transactions or activities requiring disclosure under ITRA, nor were we involved in the transactions described in this section. As of the date of this report, the Company is not aware of any other activity, transaction or dealing by it or any of its affiliates during the quarter ended September 30, 2022 that requires disclosure in this report under Section 13(r) of the Exchange Act.
