CENTURY ALUMINUM COMPANY

Condensed Notes to the Consolidated Financial Statements

Three and nine months ended September 30, 2015 and 2014

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

(Unaudited)


1.	General

The accompanying unaudited interim consolidated financial statements of Century Aluminum Company should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2014. 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 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. 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.	Ravenswood impairment

At June 30, 2015, we recorded an impairment charge of $30,850 related to the Ravenswood, West Virginia aluminum smelter. The charge included $21,500 to write down property, plant and equipment to estimated net salvage value and $7,800 to write down inventory to its net realizable value. We also accrued $1,550 for employee severance and other exit costs which are expected to be substantially paid by the end of 2015.

On July 27, 2015, we announced the immediate and permanent closure of Ravenswood. The Ravenswood smelter has been idled since February 2009. The decision to permanently close the Ravenswood smelter was based on the inability to secure a competitive power contract for the smelter, compounded by challenging aluminum market conditions largely driven by increased exports of aluminum from China. As a result, the economics of restarting and operating the facility are unfavorable.

The Ravenswood assets of $32,067 are classified as "Assets held for sale" on our Consolidated Balance Sheets as of September 30, 2015 and are expected to be sold over the next twelve months. The major components of the assets include inventory of $9,968 and property, plant and equipment of $22,099.

3.	Related party transactions

A summary of the significant related party transactions for the three and nine months ended September 30, 2015 and 2014 is as follows:



	Three months ended September 30,				Nine months ended September 30,
	2015		2014		2015		2014
Net sales to Glencore	$	428,018	$	324,775	$	1,517,428	$	898,931
Purchases from Glencore	86,664		69,256		328,120		194,111
Purchases from BHH	13,515		10,715		41,768		38,438

We believe that all of the related party transactions were at prices that approximate market.

Sales to Glencore

Through its ownership of our common and preferred stock, Glencore has an overall 47.6% economic ownership in Century.

We have entered into an agreement with Glencore pursuant to which we have agreed to sell, and Glencore has agreed to purchase, substantially all of our primary aluminum production in North America for 2015 and 2016 on a take-or-pay basis at market prices determined by reference to the Midwest Transaction Price plus additional negotiated product premiums.

We sell primary aluminum produced at our Grundartangi facility under a long-term sales contract with Glencore at prices based on the London Metal Exchange ("LME") price for primary aluminum plus the European Duty Paid premium and any applicable product premiums less certain other costs. We also receive tolling fees from Glencore under tolling agreements that provide for delivery of primary aluminum produced at our Grundartangi facility. The fee paid by Glencore under these tolling agreements is based on the LME price for primary aluminum plus a portion of the European Duty Paid premium.

We sold primary aluminum in 2014 to Glencore from our U.S. smelters on a spot basis at variable prices based on the LME, plus Midwest delivery and applicable product premiums.

See Note 12 Forward contracts and financial instruments for additional information about our forward physical delivery contracts and tolling agreements with Glencore.

Purchases from Glencore

We purchase alumina from Glencore on both a spot basis and under a long-term supply agreement. Glencore has agreed to supply us with alumina through 2017 at prices indexed to the LME price of primary aluminum under a long-term supply agreement. In 2014, upon mutual agreement, approximately half of the purchases under this agreement were priced based on a published alumina index. For 2015, we have agreed to price all of the purchases under this agreement based on a published alumina index. We had additional agreements to buy alumina from Glencore which expired at the end of 2014. In 2014, the pricing on these alumina purchase agreements was indexed to the LME price for primary aluminum.

Purchases from Baise Haohai Carbon Co., Ltd. ("BHH")

We own a 40% stake in BHH, a joint venture that owns a carbon anode and cathode facility located in the Guangxi Zhuang Autonomous Region of south China. We have an agreement with BHH to provide carbon anodes to Grundartangi through December 31, 2015.

4.	Business acquisitions

Acquisition of Mt. Holly aluminum smelter

On October 23, 2014, our wholly-owned subsidiary, Berkeley Aluminum Inc. ("Berkeley") entered into a stock purchase agreement (the "Stock Purchase Agreement") with Alumax Inc. ("Alumax"), a wholly-owned subsidiary of Alcoa Inc. ("Alcoa"), to acquire Alcoa’s 50.3% stake in Mt. Holly. Upon closing of the transaction on December 1, 2014, Century owns 100% of Mt. Holly. Mt. Holly, located in Goose Creek, South Carolina, employed approximately 600 people and had an annual production capacity of 231,000 tonnes of primary aluminum as of the acquisition date.

Pursuant to the terms of the Stock Purchase Agreement, Berkeley agreed to acquire all of the issued and outstanding shares of capital stock of Alumax of South Carolina Inc. ("Alumax of SC"), a wholly-owned subsidiary of Alumax, for $67,500 in cash subject to working capital and other similar adjustments. The acquisition was funded with available cash on hand. We incurred $1,087 of acquisition-related costs through December 31, 2014 and $417 during 2015. All acquisition-related costs were expensed to selling, general and administrative expenses in the period that they were incurred.

The following table summarizes all of the elements of consideration for the transaction, including the preliminary estimated fair value of contingent consideration.



	Preliminary as of December 1, 2014

Purchase price	$	67,500
Contingent consideration	13,780
Economic, working capital and other closing adjustments	(13,513		)
Total consideration transferred	$	67,767

Contingent Consideration - Earn-out provision

The Stock Purchase Agreement provides for a post-closing cash payment to be made following December 31, 2015 based on (i) changes in the Midwest Transaction Price for aluminum between July 2, 2014 and December 31, 2015 and (ii) the aggregate cast house production of Mt. Holly from October 1, 2014 through December 31, 2015. The maximum amount of this post-closing cash payment by (i) Century Aluminum of South Carolina, Inc. ("CASC") to Alumax is $22,500 and (ii) Alumax to CASC is $12,500. We recognized a $13,780 liability at December 1, 2014. Each period, until the end of the measurement period on December 31, 2015, we will remeasure the fair value of the contingent consideration with any changes in the fair value recognized in earnings. We classified the contingent consideration within Level 3 of the fair value hierarchy as its fair value was determined with inputs that are not readily observable in the market. For the three and nine months ended September 30, 2015, we recognized $1,523 and $18,337, respectively, in unrealized gain on fair value of contingent consideration, primarily related to decreases in the Midwest premium and the forward curve of the LME price of primary aluminum.

Economic Adjustment, working capital and other adjustments

The Stock Purchase Agreement provides for an economic adjustment that was established to put the parties in the same economic position as if the closing date for the acquisition had occurred on September 30, 2014. We received $11,189 from Alcoa for the economic adjustment in April 2015.

The Stock Purchase Agreement also contained provisions for working capital adjustments. The working capital adjustment was based on actual working capital at closing compared to established working capital targets. We received $124 from Alcoa for the working capital adjustments in April 2015.

Other adjustments include amounts due to Century for expected future post-employment benefit payments. We received $2,400 from Alcoa for these other adjustments at closing.

Step Acquisition

We accounted for this transaction as a step acquisition which required that we remeasure our prior 49.7% ownership interest, which was previously accounted for as an equity method investment, to fair value. The fair value of our interest in Mt. Holly was $47,700, resulting in a non-cash pre-tax gain of $15,956. $14,638 of that gain was recorded retroactively to the closing date resulting in an adjustment to Accumulated Deficit in the Consolidated Balance Sheets as of December 31, 2014. Our previously recorded equity method investment in Mt. Holly and the proportionally consolidated property, plant and equipment was derecognized from our Consolidated Balance Sheets. Since the date of the step acquisition, the financial results of Mt. Holly and all of its operating assets have been included within our consolidated financial statements.

The allocation of the purchase price ($67,767) and the fair value of the previous equity investment ($47,700) to all of the assets acquired and liabilities assumed is based on the estimated fair values at the date of acquisition. The following purchase price allocation is preliminary and subject to change based on the finalization of the valuation of acquired assets and liabilities.



	Preliminary estimate of the acquisition date fair value as of December 1, 2014		Measurement period adjustments			Adjusted preliminary estimate of the acquisition date fair value as of December 1, 2014
Assets Acquired:
Inventories	$	26,105	$	(2,126	)	$	23,979

Intangible asset	2,580		—			2,580
Pension asset	30,842		—			30,842
Property, plant and equipment – net	127,089		15,748			142,837
Total assets acquired	$	209,929	$	4,105		$	214,034
Liabilities Assumed:
Accounts payable, trade	$	41,471	$	—		$	41,471
Accrued and other current liabilities	8,335		255			8,590
Accrued pension benefit costs	—		34,595			34,595
Accrued postretirement benefit costs	2,857		—			2,857
Asset retirement obligations	8,213		—			8,213
Deferred taxes	4,804		(2,118		)	2,686
Total liabilities assumed	$	65,680	$	32,732		$	98,412
Goodwill	$	4,804	$	(4,804	)	$	—

We have adjusted the purchase price allocation to appropriately reflect the liability for the pension funding obligations that we assumed as of the acquisition date, pursuant to the Stock Purchase Agreement. Additionally, we have revised the Consolidated Statements of Cash Flows related to payments made in the second quarter of 2015 to satisfy the pension obligation as well as certain alumina purchases out of investing activities and into operating activities.

Pension funding obligations

Pursuant to the Stock Purchase Agreement, Alcoa spun-off the pension plan assets for the current and former Mt. Holly employees into a qualified defined benefit plan established by Century. Alcoa and Century agreed to fund their proportionate share of the underfunded Mt. Holly pension plan benefit obligations, measured in accordance with generally accepted accounting principles in the United States ("GAAP") using agreed upon assumptions as of the transaction date. In addition, Century agreed to fund any additional amount needed to bring the Mt. Holly pension benefit obligations to fully funded status on a termination basis under IRS Code Section 414(l) (the "414(l) liability"). In April 2015, Century contributed a total of $34,595 to satisfy its pension plan funding obligations under the Stock Purchase Agreement. The Pension Benefit Guaranty Corporation (the "PBGC") assumptions used for termination basis funding are more conservative than those used for GAAP purposes and resulted in the recognition of a pension asset for the over funded plan.

Settlement of amounts due from Alumax

Prior to the closing date, the Mt. Holly partnership had amounts due from Alumax for metal off-take, capital, plant administrative, standard cost true-ups and various other costs. These amounts totaling $11,269 were received at closing.

The following unaudited pro forma financial information for the three and nine months ended September 30, 2014 reflects our results of continuing operations as if the acquisition of the remaining interest in Mt. Holly had been completed on January 1, 2014. 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, 2014, nor is it indicative of the future consolidated results of operations or financial position of the combined companies.

Transactions Recognized Separately from the Mt. Holly acquisition

As part of the acquisition, we recognized certain transactions as separate and apart from the business combination with Mt. Holly. The Mt. Holly smelter tolled alumina for its partners and so had no alumina supply of its own. Upon the purchase, we negotiated with Alcoa to purchase $14,880 of alumina inventory under two separate alumina supply agreements. We believe the price paid under these agreements was equivalent to a market rate that would be paid by a market participant. Contract prices were based on published alumina price indexes.


5.	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 ("ASC") 820 "Fair Value Measurements and Disclosures."



Overview of Century’s valuation methodology
	Level	Significant inputs
Cash equivalents	1	Quoted market prices
Trust assets (1)	1	Quoted market prices
Surety bonds	1	Quoted market prices

(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.

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. Considerations 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.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and the placement within the fair value hierarchy levels. There were no transfers between Level 1 and 2 during the periods presented. There were no transfers into or out of Level 3 during the periods presented. It is our policy to recognize transfers into and transfers out of Level 3 as of the date of the event or change in circumstances that caused the transfer.

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. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive common shares outstanding.

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

Our Series A Convertible Preferred Stock is a non-cumulative perpetual participating convertible preferred stock with no set dividend preferences. In periods where we report net losses, we do not allocate these losses to the convertible preferred stock for the computation of basic or diluted EPS.

(1)

In periods when we report a net loss, all share awards are excluded from the calculation of diluted weighted average shares outstanding because of their antidilutive effect on earnings (loss) per share. In periods when we report net income, certain option awards may be excluded from the calculation of diluted EPS if the exercise price of the option award was greater than the average market price of the underlying common stock.

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 common stock repurchase program. In 2015, our Board expanded the repurchase program by approving an additional $70,000, increasing the authorization to repurchase up to $130,000. From August 2011 through September 30, 2015, we repurchased 7,186,521 shares of common stock for an aggregate purchase price of $86,276. There were no share repurchases for the three months ended September 30, 2015. During the nine months ended September 30, 2015, we repurchased 2,400,000 shares of common stock for an aggregate purchase price of $36,352. At September 30, 2015, we had approximately $43,724 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.

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.

Series A Convertible Preferred Stock

Glencore holds all of the issued and outstanding Series A Convertible Preferred Stock. The issuance of common stock under our stock incentive programs, debt exchange transactions and any stock offering that excludes Glencore participation triggers anti-dilution provisions of the preferred stock agreement and results in the automatic conversion of Series A Convertible Preferred Stock shares into shares of common stock.

The Common and Preferred Stock Activity table below contains additional information about preferred stock conversions during the nine months ended September 30, 2015 and 2014.



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

8.	Income taxes

We recorded an income tax benefit for the three months ended September 30, 2015 of $2,161 and income tax expense of $12,205 for the nine months ended September 30, 2015 respectively, which primarily consisted of foreign and state income taxes. Our domestic and certain foreign deferred tax assets, net of deferred tax liabilities, are subject to a valuation allowance.

We recorded income tax expense for the three and nine months ended September 30, 2014 of $6,444 and $7,004, respectively, which primarily consisted of foreign and state income taxes.

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

As of September 30, 2015, 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.


9.	Inventories



Inventories consist of the following:	September 30, 2015		December 31, 2014
Raw materials	$	78,066	$	78,599
Work-in-process	49,597		33,941
Finished goods	18,412		19,969
Operating and other supplies	152,784		150,971
Total inventories	$	298,859	$	283,480

Inventories are stated at the lower of cost or market.


10.	Debt



	September 30, 2015		December 31, 2014
Debt classified as current liabilities:
Hancock County industrial revenue bonds ("IRBs") due 2028, interest payable quarterly (variable interest rates (not to exceed 12%)) (1)	$	7,815	$	7,815
Debt classified as non-current liabilities:
7.5% senior secured notes due June 1, 2021, net of debt discount of $2,822 and $3,112, respectively, interest payable semiannually	247,178		246,888
Total	$	254,993	$	254,703


(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 September 30, 2015 was 0.22%.

U.S. Revolving Credit Facility

General. We and certain of our direct and indirect domestic subsidiaries (collectively, the "Borrowers") and Wells Fargo Capital Finance, LLC, as lender and agent, and Credit Suisse AG and BNP Paribas, as lenders, are parties to an Amended and Restated Loan and Security Agreement, dated May 24, 2013 (as amended, the "U.S. revolving credit facility"). The U.S. revolving credit facility has a term through June 26, 2020 and provides for borrowings of up to $150,000 in the aggregate, including up to $110,000 under a letter of credit sub-facility. Any letters of credit issued and outstanding under the U.S. revolving credit facility reduce our borrowing availability on a dollar-for-dollar basis. The availability of funds under the U.S. revolving credit facility is limited by a specified borrowing base consisting of accounts receivable and inventory of the borrowers which meet the eligibility criteria.

Status of our U.S. revolving credit facility:



	September 30, 2015
Credit facility maximum amount	$	150,000
Borrowing availability, net of outstanding letters of credit	50,026
Outstanding borrowings	—
Letter of credit sub-facility amount	110,000
Outstanding letters of credit issued	63,005

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

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

Covenants. The U.S. revolving 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 springing financial covenant that requires the Borrowers to maintain a fixed charge coverage ratio of at least 1.1 to 1.0 any time availability under the U.S. revolving credit facility is less than or equal to $15,000. As of September 30, 2015, we were in compliance with all such covenants and our fixed charge coverage ratio was greater than 1.1 to 1.0.

Iceland Revolving Credit Facility

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

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

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

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

E.ON contingent obligation

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

Based on the LME forward market prices for primary aluminum at September 30, 2015 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, we recorded a gain of $1,059 and $1,059 in net gain on forward and derivative contracts for the nine months ended September 30, 2015 and 2014, respectively. In addition, we recorded interest of $(1,059) and $(1,059) in interest expense for the nine months ended September 30, 2015 and 2014, respectively. In addition, we believe that we will not have any payment obligations for the E.ON contingent obligation through the term of the agreement, which expires in 2028. However, future increases in the LME forward market may result in a partial or full derecognition of the derivative asset and a corresponding recognition of a loss.

We classified the E.ON contingent obligation within Level 3 of the fair value hierarchy as its fair value was determined with inputs that are not readily observable in the market. The following table provides information about the balance sheet location and gross amounts offset:



Offsetting of financial instruments and derivatives
	Balance sheet location	September 30, 2015			December 31, 2014

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. However, because of the inherent uncertainties in estimating environmental liabilities primarily due to unknown facts and circumstances and changing governmental regulations and legal standards regarding liability, there can be no assurance that future capital expenditures and costs for environmental compliance at currently or formerly owned or operated properties will not result in liabilities that may have a material adverse effect on our financial condition, results of operations or liquidity.

It is our policy to accrue for costs associated with environmental assessments and remedial efforts when it becomes probable that a liability has been incurred and the costs can be reasonably estimated. The aggregate environmental-related accrued liabilities were $1,419 and $1,101 at September 30, 2015 and December 31, 2014, respectively. All accrued amounts have been recorded without giving effect to any possible future recoveries. With respect to costs for ongoing environmental compliance, including maintenance and monitoring, such costs are expensed as incurred.

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

Matters relating to the St. Croix Alumina Refining Facility

We are a party to a United States Environmental Protection Agency Administrative Order on Consent (the "Order") pursuant to which certain past and present owners of an alumina refining facility at St. Croix, Virgin Islands (the "St. Croix Alumina Refinery") have agreed to carry out a Hydrocarbon Recovery Plan to remove and manage hydrocarbons floating on groundwater underlying the facility. Pursuant to the Hydrocarbon Recovery Plan, recovered hydrocarbons and groundwater are delivered to the adjacent petroleum refinery where they are received and managed. In connection with the sale of the facility by Lockheed Martin Corporation ("Lockheed") to one of our affiliates, Virgin Islands Alumina Corporation ("Vialco"), in 1989, Lockheed, Vialco and Century entered into the Lockheed-Vialco Asset Purchase Agreement. The indemnity provisions contained in the Lockheed-Vialco Asset Purchase Agreement allocate responsibility for certain environmental matters. Lockheed has tendered indemnity to Vialco. We have likewise tendered indemnity to Lockheed. Through September 30, 2015, we have expended approximately $1,085 on the Hydrocarbon Recovery Plan. At this time, we are not able to estimate the amount of any future potential payments under this indemnification to comply with the Order, but we do not anticipate that any such amounts will have a material adverse effect on our financial condition, results of operations or liquidity, regardless of the final outcome. Vialco sold the St. Croix Alumina Refinery to St. Croix Alumina, LLC, a subsidiary of Alcoa in 1995.

In December 2010, Century was among several defendants named in a lawsuit filed by plaintiffs who either worked, resided or owned property in the area downwind from the St. Croix Alumina Refinery. In March 2011, Century was also named a defendant in a nearly identical suit brought by certain additional plaintiffs. The plaintiffs in both suits allege damages caused by the presence of red mud and other particulates coming from the alumina facility and are seeking unspecified monetary damages, costs and attorney fees as well as certain injunctive relief. We tendered indemnity and defense to St. Croix Alumina LLC and Alcoa Alumina & Chemical LLC under the terms of an acquisition agreement relating to the facility and have filed motions to dismiss plaintiffs’ claims. In August 2015, the Superior Court of the Virgin Islands, Division of St. Croix denied the motions to dismiss but ordered all plaintiffs to refile individual complaints. At this time, it is not practicable to predict the ultimate outcome of or to estimate a range of possible losses for any of the foregoing actions relating to the St. Croix Alumina Refinery.

Legal Contingencies

In addition to the foregoing matters, we have pending against us or may be subject to various lawsuits, claims and proceedings related primarily to employment, commercial, stockholder, safety and health matters. While the results of such litigation matters and claims cannot be predicted with certainty, we believe that the final outcome of such matters will not have a material adverse impact on our financial position or results of operations. However, because of the nature and inherent uncertainties of litigation, should the outcome of these actions be unfavorable, our business, financial condition, and results of operations could be materially and adversely affected.

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

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

Ravenswood Retiree Medical Benefits changes

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, 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. These actions, entitled Dewhurst, et al. v. Century Aluminum Co., et al., and Century Aluminum of West Virginia, Inc. v. United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union, AFL-CIO/CLC, et al., have been consolidated and venue has been set in the District Court for the Southern District of West Virginia.

In January 2010, the USW filed a motion for preliminary injunction to prevent us from implementing any modifications to the retiree medical benefits while these lawsuits are pending, which was dismissed by the trial court, and affirmed upon appeal. CAWV filed a motion for summary judgment of these actions which motion was granted on September 9, 2015. The decision of the court is currently being appealed by the USW to the Court of Appeals for the 4th Circuit.

PBGC Settlement

In June 2011, the PBGC informed us that it believed a "cessation of operations" under ERISA had occurred at our Ravenswood facility as a result of the curtailment of operations at the facility. Although we disagree that a "cessation of operations" occurred, we entered into a settlement agreement with the PBGC in April 2013 to resolve the matter. Pursuant to the terms of the agreement, we will make additional contributions (above any minimum required contributions) to our defined benefit pension plans totaling approximately $17,400 over the term of the agreement. During 2013, we made contributions pursuant to this agreement of approximately $6,700. Under certain circumstances, in periods of lower primary aluminum prices relative to our cost of operations, we may defer one or more of these payments, but we would be required to provide the PBGC with acceptable security for any deferred payments. We elected to defer contributions for 2014 and 2015 under the PBGC agreement and have provided the PBGC with the appropriate security. In March 2015, we made a prepayment of the deferred PBGC contributions of $1,076.

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 2017, extending year to year thereafter unless a one year notice is given.

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 2017, extending year to year thereafter unless a one year notice is given.

Mt. Holly

Mt. Holly has a power purchase agreement (the "Santee Cooper Agreement") with the South Carolina Public Service Authority ("Santee Cooper") with an effective term through December 2015. The Santee Cooper Agreement provides power for Mt. Holly’s full production capacity requirements at prices based on published rate schedules (which are subject to change), with adjustments for fuel prices and other items. The Santee Cooper Agreement restricts Mt. Holly’s ability to reduce its power consumption (or the associated payment obligations) below contracted levels.

On October 22, 2015, we issued a notice to employees at our Mt. Holly, South Carolina aluminum smelter of our intent to curtail the Mt. Holly plant operations by no later than December 31, 2015, when our current power contract at Mt. Holly expires, if we are unable to secure a competitively priced power arrangement to deliver energy to the plant. The announcement was made pursuant to the federal Working Adjustment and Retraining Notification Act (WARN).

Grundartangi

Grundartangi 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 (subject to extension), 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 June 2012, Grundartangi entered into a supplemental power contract with Landsvirkjun. The supplemental power contract, which will expire in October 2029 (or upon the occurrence of certain earlier events), will provide Grundartangi with supplemental power, as Grundartangi may request from time to time, at LME-based variable rates. Grundartangi has agreed to make certain prepayments to Landsvirkjun for power expected to be used at a later date in connection with the contract, which will reduce the price paid for power at the time of consumption. As of September 30, 2015, these power prepayments totaled approximately $1,792.

Helguvik

Nordural Helguvik ehf ("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 power purchase agreements contain certain conditions to HS’s and OR’s obligations. HS and OR have alleged that certain of these conditions

have not been satisfied. The first stage of power under the OR power purchase agreement (approximately 47.5 MW) became available in the fourth quarter of 2011 and is currently being utilized at Grundartangi. In July 2014, HS commenced arbitration proceedings against Helguvik seeking, among other things, an order declaring, (i) that the conditions to the power contract have not been fulfilled and, (ii) that the power contract is therefore no longer valid. Helguvik believes HS' renewed claims are without merit and intends to defend itself against them. Helguvik is in discussions with OR with respect to such conditions and other matters pertaining to these agreements.

In June 2014, Helguvik entered into a supplemental power contract with OR. The supplemental power contract will expire in October 2036 (or upon the occurrence of certain earlier events) and will provide Grundartangi or Helguvik with supplemental power at LME-based rates, as may be requested from Grundartangi or Helguvik from time to time.

Other Commitments and Contingencies

Labor Commitments

The bargaining unit employees at our Grundartangi, Vlissingen, Hawesville, Sebree and Ravenswood facilities are represented by labor unions, representing 59% of our total workforce.

81% 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. A new agreement was entered into in March 2015 and is effective through December 31, 2019. 80% of Vlissingen's work force is represented by the Federation for the Metal and Electrical Industry ("FME"), governed by a labor agreement that expired on May 1, 2015. Since such time, we have been operating under the terms of the expired agreement while we engage in negotiations with the FME regarding the terms of a new agreement. The FME negotiates working conditions with trade unions on behalf of its members.

53% of our U.S. based work force is represented by the USW. In June 2015, CAKY entered into a new collective bargaining agreement with the USW for its employees at the CAKY smelter. The agreement is effective through April 1, 2020. In July 2014, Century Sebree entered into a new collective bargaining agreement with the USW for its employees at the Sebree smelter. The agreement is effective through October 28, 2019. The labor agreement for CAWV’s Ravenswood plant employees represented by the USW expired on August 31, 2010.


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.

Recent Developments

Century Aluminum issues WARN Notice at Sebree, KY smelter

Century Aluminum issues WARN Notice at Mt. Holly, SC smelter

Century Aluminum announces continued operation of two potlines at Hawesville, KY smelter

On September 30, 2015, we announced that we expect to continue to operate our Hawesville, KY aluminum smelter at approximately 40% of capacity (two potlines) following October 24, 2015. We had previously announced our intent to curtail 100% of our Hawesville operations beginning on October 24, 2015, but now will only reduce operations to approximately 40% of capacity.

Century Aluminum announces cost reduction and cash preservation program

On August 6, 2015, we announced a cost reduction and cash preservation program in response to weak primary aluminum market conditions. The program includes capacity curtailment; reductions in headcount, operating expenses and capital expenditures; and working capital liquidation. We will continue to explore further cost reduction and cash preservation opportunities. As a result of the cost reduction programs, we incurred severance-related charges of $1.2 million to be substantially settled in the second half of 2015.

Century announces the permanent closure of the Ravenswood smelter

On July 27, 2015, we announced the immediate and permanent closure of the Ravenswood, West Virginia aluminum smelter. The Ravenswood smelter has been idled since February 2009. The decision to permanently close the Ravenswood smelter was based on the inability to secure a competitive power contract for the smelter, compounded by challenging aluminum market conditions largely driven by increased exports of aluminum from China. As a result, the economics of restarting and operating the facility are unfavorable. See Note 2 Ravenswood impairment to the consolidated financial statements included herein for additional information.

Net sales (in millions)	2015		2014		$ Difference			% Difference
Three months ended September 30,	$	454.5	$	500.6	$	(46.1	)	(9.2	)%
Nine months ended September 30,	$	1,565.9	$	1,379.8	$	186.1		13.5	%

During the three months ended September 30, 2015, higher shipment volumes, due to the acquisition of the Mt. Holly smelter on December 1, 2014 and a shift from toll to direct sales at Grundartangi, had a positive impact on net sales of $44.8 million. Lower price realization had a negative impact on net sales of $90.9 million. Direct shipments from our four operating smelters increased 28,732 tonnes in the three months ended September 30, 2015 compared to the same period in 2014. Toll shipments decreased 15,906 tonnes relative to the same period last year.

During the nine months ended September 30, 2015, higher shipment volumes, due to the acquisition of the Mt. Holly smelter on December 1, 2014 and a shift from toll to direct sales at Grundartangi, had a positive impact on net sales of $188.2 million. Lower price realization had a negative impact on net sales of $2.1 million. Direct shipments from our four operating

smelters increased 95,106 tonnes in the nine months ended September 30, 2015 compared to the same period in 2014. Toll shipments decreased 25,901 tonnes relative to the same period last year.



Gross profit (loss) (in millions)	2015			2014		$ Difference			% Difference
Three months ended September 30,	$	(42.4	)	$	75.7	$	(118.1	)	(156.0	)%
Nine months ended September 30,	$	60.0		$	112.5	$	(52.5	)	(46.7	)%

During the three months and nine months ended September 30, 2015, gross profit was negatively impacted by lower price realization, unfavorable alumina pricing, the write down of our inventories to the current market value below its cost basis, and the labor disruption at our Hawesville facility. For the same periods, gross profit was favorably impacted by volume due to the acquisition of Mt. Holly.

Lower sales price realizations had a negative impact on gross profit of $90.9 million and $2.1 million for the three and nine months ended September 30, 2015, respectively. The contribution to gross profit from increased sales volume had a favorable impact on gross profit of $8.0 million and $25.4 million for the three and nine months ended September 30, 2015, respectively.

During the three and nine months ended September 30, 2015, alumina prices negatively impacted gross profit by $21.6 million and $59.0 million, respectively. For 2015, we agreed to price all of the purchases under our alumina supply agreement with Glencore based on a published alumina market index. For 2014, a majority of our purchases were indexed to the LME price for primary aluminum at index rates below 2015 market rates under a long-term alumina purchase agreement that expired December 31, 2014.

Due to the nature of our business, our inventory values are subject to fluctuations in market value and these fluctuations can have a significant impact on cost of goods sold and gross profit in any period. On average, our inventory turns eight times within a year and reductions in value below cost basis at the end of a period are the basis for inventory as it turns in subsequent periods.

As of December 31, 2014, the market value of our inventory was above its cost basis requiring no valuation adjustment. As of June 30, 2015, the market value of our inventory was below its cost basis with a lower of cost or market (“LCM”) valuation adjustment of $25.7 million. During the three months ended September 30, 2015 inventory with a $25.7 million market valuation adjustment was consumed into cost of goods sold at the lower basis. As of September 30, 2015, the market value of our inventory was below its cost basis, resulting in the recording of valuation adjustment and a charge to cost of goods sold of $31.0 million. As of December 31, 2013, the market value of our inventory was below its cost basis with an LCM valuation adjustment of $1.2 million. During the three months ended March 31, 2014, inventory with a $1.2 million market valuation adjustment was consumed into cost of goods sold at the lower basis. The net impact of the market valuation adjustments on the 2015 and 2014 comparative results is a decrease in gross profit of $5.3 million for the three month period and a decrease in gross profit of $32.2 million for the nine month period.

From May 12, 2015 until June 15, 2015, the Hawesville facility experienced a labor disruption relating to the negotiation of a new collective bargaining agreement with the bargaining unit employees at the facility. During the labor disruption, Century’s salaried employees and temporary replacement workers operated the facility. A new collective bargaining agreement for the facility was ratified on June 11, 2015 and bargaining unit employees returned to the facility on June 15, 2015. Century incurred direct expenses of $1.4 million and $13.1 million in the three and nine months ended September 30, 2015, respectively, for such things as replacement workers, internal payroll, security, supplies, services and legal fees, net of labor cost savings, during the labor disruption.

In addition to the cost increases discussed above, during the three months ended September 30, 2015, net cost at our smelters increased $6.9 million relative to the same period in 2014, comprised of: lower costs for power and natural gas, $18.9 million; increased costs at our casting operations to support our increased presence in the value-added business, $10.5 million and other cost increases of $15.3 million. During the nine months ended September 30, 2015, we experienced $23.0 million in net cost decreases at our smelters relative to the same period in 2014, comprised of: lower costs for power and natural gas, $86.5 million; increased costs at our casting operations to support our increased presence in the value-added business, $29.3 million and other cost increases of $34.2 million.

The results for the nine months ended September 30, 2014 included $5.5 million of amortization credit related to the purchase accounting for the Sebree smelter.

Nine months ended September 30,	$	33.5	$	32.8	$	0.7		2.1	%

During the nine months ended September 30, 2015, selling, general and administrative expenses were greater than the same period last year primarily due to charges related to the separation of a former senior executive.

At June 30, 2015, we recorded an impairment charge of $30.9 million related to the Ravenswood, West Virginia aluminum smelter. The charge included $21.5 million to write down property, plant and equipment to estimated net salvage value and $7.8 million to write down inventory to its net realizable value. We also accrued $1.6 million for employee severance and other exit costs which are expected to be substantially paid by the end of 2015. See Note 2 Ravenswood impairment to the consolidated financial statements included herein for additional information.

On December 1, 2014, we acquired Alcoa’s 50.3% stake in Mt. Holly. The purchase agreement provides for a post-closing payment based on changes in the Midwest Transaction Price and production levels at Mt. Holly during the applicable measuring period. The measurement period for this potential payment ends on December 31, 2015. For the three and nine months ended September 30, 2015, we recorded unrealized gains of $1.5 million and $18.3 million, respectively, on the fair value of contingent consideration, primarily related to decreases in the Midwest premium and the forward curve for the LME price of primary aluminum. See Note 4 Business acquisitions to the consolidated financial statements included herein for additional information.

We have a valuation allowance against all of our U.S. and certain foreign deferred tax assets. The significant driver of period to period differences in income tax expense is the change in earnings at our foreign entities that are not subject to a valuation allowance. See Note 8 Income taxes to the consolidated financial statements included herein for additional information.

Liquidity and Capital Resources

Liquidity

Our principal sources of liquidity are available cash, cash flow from operations and borrowing capacity under our existing revolving credit facilities. We have also raised capital in the past through the public equity and debt markets, and we regularly explore various other financing alternatives. Our principal uses of cash include the funding of operating costs (including post-retirement benefits), maintenance of curtailed production facilities, debt service requirements, the funding of capital expenditures, investments in our growth activities and in related businesses, working capital, repurchases of common stock and other general corporate requirements.

Our consolidated cash and cash equivalents balance at September 30, 2015 was approximately $123 million compared to approximately $163 million at December 31, 2014.

Availability Under Our Credit Facilities

We and certain of our direct and indirect subsidiaries are party to a senior secured revolving credit facility, dated May 24, 2013, as amended, with a syndicate of lenders which provides for borrowings of up to $150 million in the aggregate, including up to $110,000 under a letter of credit sub-facility (the "U.S. revolving credit facility"). We have also entered into, through our wholly-owned subsidiary Nordural Grundartangi ehf, a $50 million revolving credit facility, dated November 27, 2013 (the "Iceland revolving credit facility"). Our U.S. revolving credit facility matures in June 2020 and our Iceland revolving credit facility matures in November 2016.

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. As of September 30, 2015, our credit facilities had approximately $100 million of net availability, after consideration of our outstanding letters of credit. Curtailments of production capacity decrease our borrowing base by reducing our accounts receivable and inventory balances. We borrow and make repayments under our credit facilities in the ordinary course based on a number of factors, including the timing of payments from our customers and payments to our suppliers. We did not have a material amount of borrowings and repayments under our credit facilities for the nine months ended September 30, 2015.

As of September 30, 2015, we had approximately $63 million of letters of credit outstanding under our U.S. revolving credit facility with 74% related to our domestic power commitments and the remainder securing certain debt and workers' compensation commitments. With the acquisition of Mt. Holly, Santee Cooper required us to post a letter of credit to secure our power obligations under the existing power contract. As of September 30, 2015, we had a $32 million letter of credit with Santee Cooper, which decreases automatically on a monthly basis by an amount between $4 and $6 million until the letter of credit expires in February 2016. The existing power contract at Mt. Holly expires on December 31, 2015 and, to date, we have been unable to reach an agreement for the delivery of power to Mt. Holly following such date. On October 22, 2015, we issued a notice to Mt. Holly employees of our intent to curtail 100% of the Mt. Holly smelter operations by no later than December 31, 2015 if a competitively priced power arrangement has not been secured. Our letter of credit obligations with respect to power at Mt. Holly will depend on whether we are successful in securing a power arrangement following December 31, 2015 or, alternatively, if production is curtailed.

On January 1, 2015, EDF replaced Big Rivers as our market participant with MISO for our power supply arrangements in Kentucky. The transition to EDF reduced our outstanding letters of credit by approximately $40 million, however future collateral requirements can fluctuate with power prices and other factors beyond our control.

Senior Secured Notes

We have $250 million in 7.5% senior secured notes payable that will mature on June 1, 2021.

Acquisitions

On December 1, 2014, we acquired Alcoa’s 50.3% stake in Mt. Holly for $67.5 million in cash subject to working capital and several other adjustments. The acquisition was funded with available cash on hand.

In addition, the purchase agreement provides for a post-closing cash payment to be made following December 31, 2015 based on changes in the Midwest Transaction Price between July 2, 2014 and December 31, 2015 and production levels at Mt. Holly from October 1, 2014 through December 31, 2015. The maximum amount of this post-closing cash payment by Century to Alcoa is $22.5 million and by Alcoa to Century is $12.5 million. Based on current market conditions, we estimate that Alcoa would be obligated to pay Century $12.5 million in the first quarter of 2016 for this post-closing payment. See Note 4 Business acquisitions to the consolidated financial statements included herein for additional information.

Contingent Commitments

We have a contingent obligation to E.ON which consists of the aggregate E.ON payments made to Big Rivers on CAKY’s behalf in excess of the agreed upon base amount under the long-term cost-based power contract with Kenergy. As of September 30, 2015, the principal and accrued interest for the E.ON contingent obligation was $19.3 million, which was fully offset by a derivative asset. We may be required to make installment payments for the E.ON contingent obligation in the future. These payments are contingent based on the LME price of primary aluminum and the level of Hawesville’s operations. Based on the LME forward market at September 30, 2015 and management’s estimate of the LME forward market beyond the quoted market period, we have assessed that we will not be required to make payments on the E.ON contingent obligation during the term of the agreement through 2028. There can be no assurance that circumstances will not change, thus accelerating the timing of such payments. See Note 10 Debt to the consolidated financial statements included herein for additional information.

Employee Benefit Plan Contributions

In 2013, we entered into a settlement agreement with the PBGC regarding an alleged "cessation of operations" at our Ravenswood facility as a result of the curtailment of operations at the facility. Pursuant to the terms of the agreement, we will make additional contributions (above any minimum required contributions) to our defined benefit pension plans over the term of the agreement. The remaining contributions under this agreement are approximately $9.6 million, of which approximately $3.7 million and $4.0 million were scheduled to be made in 2014 and 2015, respectively. Under certain circumstances, in periods of low primary aluminum prices relative to our operations, we may defer one or more of these payments, but we would be required to provide the PBGC with acceptable security for any deferred payments. In 2014 and 2015, we elected to defer contributions under the PBGC agreement and have provided the PBGC with the appropriate security. In March 2015, we made a prepayment of the deferred PBGC contributions of $1.1 million.

In addition to the contributions required pursuant to the PBGC settlement, we expect to make contributions of $5.9 million to our qualified defined benefit plans and an unqualified supplemental executive retirement benefits ("SERB") plan. Through September 30, 2015, we made contributions of $4.9 million. We made a contribution to the Mt. Holly defined benefit plan of $34.6 million to satisfy our pension plan funding obligations under the Stock Purchase Agreement. See Note 4 Business acquisitions.

Other items

In February 2015, Nordural ehf participated in the 50/50 ISK Auctions (the "Auctions") sponsored by the Central Bank of Iceland ("CBI") and may participate in future Auctions. The Auctions allow authorized investors to exchange foreign currency for ISK with 50% exchanged at the official rate set by the CBI and 50% exchanged at the Auction rate. The ISK received in the Auction must be invested in Iceland for a minimum of five years.

In May 2015, we paid Icelandic withholding taxes on intercompany dividends of approximately $8.4 million, which we anticipate will be refunded in November 2016. During 2014, we paid Icelandic withholding taxes on intercompany dividends of approximately $5.5 million, which we anticipate will be refunded in November 2015. The withholding taxes and associated refunds are payable in Icelandic kronur ("ISK") and we are subject to foreign currency risk associated with fluctuations in the value of the U.S. dollar as compared to the ISK.

In August 2011, our Board of Directors approved a $60 million common stock repurchase program. In 2015, our Board expanded the repurchase program by approving an additional $70 million, increasing the authorization to repurchase up to $130 million. Through September 30, 2015, we had expended approximately $86.3 million under the program and repurchased 7.2 million common shares. During the nine months ended September 30, 2015, we repurchased 2.4 million common shares for $36.4 million. At September 30, 2015, we had approximately $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.

We are also 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 recurring capital expenditures from available cash, cash flow from operations and available borrowing capacity under our existing revolving credit facilities. For major investment projects, such as the Helguvik project, we would likely seek financing from various capital and loan markets, and may potentially pursue the formation of strategic alliances. We may be unable, however, to issue additional debt or equity securities, or enter into other financing arrangements on attractive terms, or at all, due to a number of factors including a lack of demand, unfavorable pricing, poor economic conditions, unfavorable interest rates, or our financial condition or credit rating at the time. Future uncertainty in the U.S. and international markets and economies may adversely affect our liquidity, our ability to access the debt or capital markets and our financial condition.

Capital expenditures for the nine months ended September 30, 2015 were $47.6 million. We believe total capital spending in 2015 will be approximately $60 million, primarily related to our ongoing expansion project at Grundartangi, our restart of the second furnace at Vlissingen and other investment projects at our North American facilities.

We have made and continue to make capital expenditures for the construction and development of our Helguvik project. We have substantial future contractual commitments for the Helguvik project. If we were to cancel the Helguvik project, we estimate that our exposure to contract cancellation and other costs would be approximately $20 million, of which we currently have accrued liabilities of approximately $12.3 million. We are continuing to negotiate with the power suppliers to the project to, among other things, remove all the remaining conditions to their obligations to supply contracted power. The timing of the power availability together with other factors will determine the timing of resumption of major construction activity at Helguvik. We expect that capital expenditures for this project will be less than $0.5 million per year until the restart of major construction activities. We cannot, at this time, predict when the restart of major construction activity will occur.

Adjusted EBITDA

We believe the presentation of adjusted EBITDA is a useful measure to help investors evaluate our capacity to fund our ongoing cash operating requirements, including capital expenditures and debt service obligations. Adjusted EBITDA should not be considered as a substitute for operating income (loss) as determined in accordance with GAAP.

The following table includes a reconciliation of operating income (loss) to the most comparable GAAP financial measure, adjusted EBITDA.

Historical

Our statements of cash flows for the nine months ended September 30, 2015 and 2014 are summarized below:



	Nine months ended September 30,
	2015			2014
	(in thousands)
Net cash provided by operating activities	$	32,509		$	97,714
Net cash used in investing activities	(36,423		)	(39,938		)
Net cash used in financing activities	(36,352		)	(8,454		)
Change in cash and cash equivalents	$	(40,266	)	$	49,322

Net cash provided by operating activities for the nine months ended September 30, 2015 was $32.5 million, compared to $97.7 million for the nine months ended September 30, 2014. Significant items contributing to decreases in cash provided by operating activities include: a decrease in net income of $66.9 million, a cash payment of $34.6 million for pension funding obligations related to our purchase of Mt. Holly and the unrealized gain on fair value of contingent consideration of $18.3 million. Significant items partially offsetting the decreases include: a lower of cost or market inventory adjustment of $32.3 million and the Ravenswood impairment charge of $30.9 million.

Our net cash used in investing activities for the nine months ended September 30, 2015 was $36.4 million, compared to $39.9 million for the nine months ended September 30, 2014. We received the economic and working capital adjustments of $11.3 million from Alcoa related to the acquisition of Mt. Holly and capital expenditures increased by $8.2 million compared to 2014.

Our net cash used in financing activities for the nine months ended September 30, 2015 was $36.4 million, compared to $8.5 million for the nine months ended September 30, 2014. The change was primarily related to repurchases of $36.4 million of common stock in 2015 related to our share repurchase program partially offset by $6.0 million in net paydowns on our revolving line of credit in 2014.

Critical Accounting Estimates

Inventories

Inventories are stated at lower of cost or market.

Our estimate of the market value of our inventories involves establishing a net realizable value for both finished goods and the components of inventory that will be converted to finished goods, raw materials and work in process. This requires

management to use its judgment when making assumptions about future selling prices and the costs to complete our inventory during the period in which it will be sold.

Our assumptions are subject to inherent uncertainties given the volatility surrounding the market price for primary aluminum sales and the market price for one of our major inputs, electrical power.

Although we believe that the assumptions used to estimate the market value of our inventory are reasonable, actual market conditions at the time our inventory is sold may be more or less favorable than management’s current estimates.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

Commodity Price Sensitivity

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

For information about our long-term primary aluminum metal sales and tolling agreement, see Note 12 Forward delivery contracts and financial instruments to the consolidated financial statements included herein.

Other Forward Delivery Contracts



	September 30, 2015	December 31, 2014
	(in tonnes)
Other forward delivery contracts – total	6,486	6,108
Other forward delivery contracts – Glencore	—	4,058

We had no significant outstanding primary aluminum forward financial sales contracts or significant fixed price forward financial contracts to purchase aluminum at September 30, 2015.

Market-Based Power Price Sensitivity

Market-Based Electrical Power Agreements

Hawesville and Sebree have market-based electrical power agreements. Under the market-based power agreements, EDF and Kenergy purchase market-based electrical power on the open market and pass it through to Hawesville and Sebree at MISO pricing, plus transmission and other costs incurred by them.

Electrical Power Price Sensitivity

With the movement toward market-based power supply agreements, we have increased our electrical power price risk for our domestic operations due to fluctuations in the price of power available on the MISO market. Power represents our single largest operating cost, so changes in the price and/or availability of market power could significantly impact the profitability and viability of our Hawesville, Sebree and Mt. Holly operations. Transmission line outages, problems with grid stability or limitations on energy import capability could also increase power prices, disrupt production through pot instability or force a curtailment of all or part of the production at these facilities. In addition, indirect factors that lead to power cost increases, such as any increasing prices for natural gas or coal, fluctuations in or extremes in weather patterns or new or more stringent environmental regulations may severely impact our financial condition, results of operations and liquidity.

The following table provides electrical power price sensitivity by location and assumes operating at full capacity:



Electrical power price sensitivity by location:
	Hawesville (1)		Sebree		Total
Expected average load (in megawatts ("MW"))	482		385		867
Quarterly estimated electrical power usage (in megawatt hours ("MWh"))	1,055,580		843,150		1,898,730
Quarterly cost impact of an increase or decrease of $1 per MWh (in thousands)	$	1,100	$	800	$	1,900
Annual expected electrical power usage (in MWh)	4,222,320		3,372,600		7,594,920
Annual cost impact of an increase or decrease of $1 per MWh (in thousands)	$	4,200	$	3,400	$	7,600

(1) The operations at Hawesville are currently operating at approximately 40% of full capacity.

While we currently have not entered into any forward contracts to mitigate the price risk associated with our open market power purchases, we may manage our exposure by entering into certain forward contracts or option contracts in future periods.

Foreign Currency

We are exposed to foreign currency risk due to fluctuations in the value of the U.S. dollar as compared to the ISK, the euro, the Chinese yuan and other currencies. Grundartangi’s labor costs, part of its maintenance costs and other local services are denominated in ISK and a portion of its anode costs are denominated in euros and the Chinese yuan. We have deposits denominated in ISK in Icelandic banks; in addition, our tax payments in Iceland for withholding taxes on intercompany dividends and estimated payments of Icelandic income taxes and any associated refunds are denominated in ISK. As a result, an increase or decrease in the value of those currencies relative to the U.S. dollar would affect Grundartangi’s operating margins. We expect to incur significant capital expenditures for Vlissingen in 2015, primarily denominated in euros. In addition, Vlissingen's labor costs, maintenance costs and other local services are denominated in euros. We expect to incur additional capital expenditures for the construction of the Helguvik project, although we continue to evaluate the Helguvik project’s cost, scope and schedule. Upon a restart of major construction for the Helguvik project, we have forecasted that a significant portion of the capital expenditures would be denominated in currencies other than the U.S. dollar, with significant portions in ISK, euros and Swiss francs.

We may manage our exposure by entering into foreign currency forward contracts or option contracts for forecasted transactions and projected cash flows for foreign currencies in future periods.

Natural Economic Hedges

Any analysis of our exposure to the commodity price of aluminum should consider the impact of natural hedges provided by certain contracts that contain pricing indexed to the LME price for primary aluminum. Certain of our alumina contracts, as well as certain of Grundartangi’s electrical power and tolling contracts, are indexed to the LME price for primary aluminum and provide a natural hedge for a portion of our production.

Risk Management

Our metals, power, natural gas and foreign currency risk management activities are subject to the control and direction of senior management within guidelines established by Century’s Board of Directors. These activities are regularly reported to Century’s Board of Directors.

Item 4. Controls and Procedures.

a. Evaluation of Disclosure Controls and Procedures

As of September 30, 2015, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures. Based upon that evaluation, our management, including the Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective as of September 30, 2015.

b. Changes in Internal Control over Financial Reporting

During the three months ended September 30, 2015, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. On December 1, 2014, we acquired the remaining interest in the Mt. Holly smelter and we are currently in the process of extending our internal control over financial reporting to Mt. Holly's operations.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings.

We are a party from time to time in various legal actions arising in the normal course of business, the outcomes of which, in the opinion of management, neither individually nor in the aggregate are likely to result in a material adverse effect on our financial position, operating results and cash flows. For information regarding legal proceedings pending against us at September 30, 2015, refer to Note 11 Commitments and contingencies to the consolidated financial statements included herein.

Item 1A. Risk Factors.

The following is an update to certain of the risk factors set forth in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014. Other than the following update, there have been no material changes from the risk factors previously disclosed under the heading “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 and our Quarterly Report on Form 10-Q for the quarter ended June 30, 2015. You should carefully consider the risk factors set forth below and those contained in our Annual Report on Form 10-K, our Quarterly Reports on Form 10-Q and our other filings made with the Securities and Exchange Commission. 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.

If we are unable to enter into a new power contract for Mt. Holly, we may be unable to operate Mt. Holly at a profitable level or at all.

Mt. Holly purchases power pursuant to a power purchase agreement (the "Santee Cooper Agreement") with the South Carolina Public Service Authority ("Santee Cooper"). The term of the Santee Cooper Agreement expires on December 31, 2015. To date, we have been unable to reach an agreement with Santee Cooper to deliver power to Mt. Holly following December 31, 2015 and on October 22, 2015 we issued a notice to Mt. Holly employees of our intent to curtail 100% of the Mt. Holly smelter operations by no later than December 31, 2015 if a competitively priced power arrangement has not been secured. Closure of the Mt. Holly facility would impose various costs on us that could have a material adverse effect on our business, financial condition, results of operations and liquidity. In addition, the ongoing uncertainty regarding the future operation of Mt. Holly may damage our relationships with our customers, suppliers, employees and other stakeholders, whether or not Mt. Holly is ultimately closed. We may need to take actions to terminate certain customer and supply contracts or curtail individual potlines in advance of any plant closure. Customers and suppliers may also become unwilling to renew existing contracts or enter into new contracts with us. It may also become more difficult to attract and retain employees. Such actions and events could have a material adverse effect on our business, financial condition, results of operations and liquidity.

Curtailment of aluminum production at our facilities could have a material adverse effect on our business, financial position, results of operations and liquidity.

Recent significant declines in the aluminum price have caused us to partially curtail production at our Hawesville, Kentucky smelter, which is currently operating at approximately 40% of capacity, and we have also announced our intent to curtail one potline at our Sebree, Kentucky smelter by December 31, 2015. There can be no assurance that continued deterioration in the price of aluminum will not result in additional production curtailments at our U.S. facilities. Furthermore, on October 22, 2015, we announced our intent to curtail 100% of the Mt. Holly smelter operations by no later than December 31, 2015 if a competitively priced power arrangement has not been secured.

Curtailing production requires us to incur substantial expenses, both at the time of the curtailment and on an ongoing basis. Our facilities are subject to contractual and other fixed costs that continue even if we curtail operations at these facilities. These costs reduce the cost saving advantages of curtailing aluminum production.

If we are unable to realize the intended cost saving effects of any production curtailment, we may have to seek bankruptcy protection for some or all of our subsidiaries; we could also be forced to divest some or all of these subsidiaries. If we were to seek bankruptcy protection for any of these subsidiaries, we would face additional risks. Such action could cause concern among our customers and suppliers, distract our management and our other employees and subject us to increased risks of lawsuits. Other negative consequences could include negative publicity, which could have an impact on the trading price of our securities and affect our ability to raise capital in the future.

Any curtailments of our operations, or actions taken to seek bankruptcy protection or divest some or all of our subsidiaries, could have a material adverse effect on our business, financial position, results of operations and liquidity.

Certain of our raw material and services contracts contain "take-or-pay" obligations.

We have obligations under certain contracts to take-or-pay for specified raw materials or services over the term of those contracts regardless of our operating requirements. Even though we have curtailed production at our Hawesville smelter to 40% of production capacity and to the extent that we curtail production at our other U.S. operations, including Mt. Holly or Sebree, we continue to be obligated under these contracts which reduces the cost savings advantages of curtailing unprofitable aluminum production. Our financial position and results of operations may also be adversely affected by the market price for such materials or services as we will continue to incur costs under these contracts to meet or settle our contractual take-or-pay obligations. If we were unable to use such materials or services in our operations or sell them at prices consistent with or greater than our contract costs, we could incur significant losses under these contracts. In addition, these commitments may also limit our ability to take advantage of favorable changes in the market prices for such materials and may have a material adverse effect on our business, financial position, results of operations and liquidity.

We may be required to write down the book value of certain assets.

We perform various analyses related to the carrying value of various assets whenever events or circumstances indicate that their net carrying amount may not be recoverable. Given changes in the extent and manner our assets are being used, changes in certain factors critical to our industry, as well as recent global economic conditions, which in part drive assumptions for the future in such analyses, we could have significant adjustments in the carrying value for certain assets. For instance, on July 27, 2015 we announced the permanent closure of our Ravenswood, West Virginia smelter which had been idled since 2009. In connection with the permanent closure of Ravenswood we recorded an impairment charge of approximately $30.9 million. The charge included approximately $21.5 million to write down property, plant and equipment to estimated net salvage value and approximately $7.8 million to write down inventory to its net realizable value. If we are unable to reach a competitively priced power arrangement for our Mt. Holly smelter prior to December 31, 2015, or if we decide not to complete the Helguvik project, we may recognize a loss related to all or a portion of the assets of these facilities. Any such adjustments would be in the form of a non-cash charge which would reduce our earnings and increase our accumulated deficit. Any of the foregoing could have a material adverse effect on our business, financial position and results of operations.

In August 2011, our Board of Directors approved a $60 million common stock repurchase program. In the first quarter of 2015, our Board expanded the repurchase program by approving an additional $70 million. Under the expanded program, Century is authorized to repurchase up to $130 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. The stock repurchase program may be suspended or discontinued at any time.
