CENTURY ALUMINUM COMPANY

Condensed Notes to the Consolidated Financial Statements

Three and nine months ended September 30, 2017 and 2016

(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, 2016. 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 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017. 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.

Accounting Standards Update ("ASU") 2014-09 "Revenue From Contracts with Customers (Topic 606)" issued by the Financial Accounting Standards Board ("FASB"), outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The ASU is effective for Century beginning January 1, 2018.

Through September 30, 2017, we have reviewed our 2017 customer contracts and drafts and amendments of our contracts that will become effective beginning January 1, 2018. Based on our assessment completed to date, other than the additional disclosure requirements, we do not expect the adoption of ASU 2014-09 to significantly change our business processes, controls and systems, or change the timing or amount of revenue recognized. We continue to monitor modifications, clarifications or interpretations undertaken by the FASB and the Securities and Exchange Commission ("SEC") and changes in our business and new arrangements, which may impact our current conclusions. We expect to adopt the standard on a modified retrospective basis.


2.	Related party transactions

Our significant related party transactions occurring during the nine months ended September 30, 2017 and 2016 are described below. We believe that all of the transactions with our related parties were on terms that approximate market.

Glencore ownership

As of September 30, 2017, Glencore plc and its affiliates (together "Glencore") beneficially owned 42.9% of Century’s outstanding common stock (47.4% 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. From time to time Century and Glencore enter into various transactions for the purchase and sale of primary aluminum, purchase and sale of alumina, tolling agreements and certain forward financial contracts.

Sales to Glencore

For the three months ended September 30, 2017 and 2016 we derived approximately 75% and 90%, respectively, of our consolidated sales from Glencore, while for the nine months ended September 30, 2017 and 2016, approximately 76% and 89%, respectively, of our consolidated sales were derived from Glencore.

We have entered into agreements with Glencore pursuant to which Glencore has agreed to purchase aluminum produced from our U.S. and Icelandic operations through 2017. Glencore purchases aluminum produced at our North American smelters at prices based on the London Metal Exchange (the "LME") price for primary aluminum plus the Midwest regional delivery premium and any additional negotiated product premiums. Glencore purchases aluminum produced at our Grundartangi, Iceland smelter in 2017 at prices based on the LME plus the European Duty Paid premium and any applicable product premiums.

Glencore purchases the aluminum we produce for resale.

Purchases from Glencore

We purchase alumina from Glencore under a long-term supply agreement and on a spot basis. Pursuant to our current agreement, Glencore has agreed to supply us with alumina through 2017 at prices indexed to the LME price of primary aluminum. In 2016 and 2017, upon mutual agreement, all of our purchases from Glencore under this agreement were priced based on a published alumina index.

Financial contracts with Glencore

During 2017, we entered into certain financial contracts with Glencore. Refer to Note 13 Derivatives to the consolidated financial statements included herein.

Transactions with 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, 2017.

Summary

A summary of the aforementioned significant related party transactions for the three and nine months ended September 30, 2017 and 2016 is as follows:



	Three months ended September 30,				Nine months ended September 30,
	2017		2016		2017		2016
Net sales to Glencore	$	299,235	$	301,111	$	876,079	$	871,771

Purchases from BHH	3,248		2,568		9,137		7,666


3.	Fair value measurements

The following section describes the valuation methodology used to measure our financial assets and liabilities that were accounted for at fair value and are categorized based on the fair value hierarchy described in 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
Forward financial sales	2	Quoted market prices
Fixed for floating swaps	3	Quoted market prices, management's estimates of future U.S. Midwest premium
Contingent obligation	3	Quoted market prices, management’s estimates of the LME forward market prices for periods beyond the quoted periods and management’s estimate of future level of operations

(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.

(Unaudited)

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.

The following table sets forth our financial assets and liabilities that were accounted for at fair value on a recurring basis by the level of input within the ASC 820 fair value hierarchy.

4.	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 dilutive securities.

The following table shows the basic and diluted earnings (loss) per share for the three and nine months ended September 30, 2017 and 2016:



	For the three months ended September 30,

5.	Shareholders’ equity

Common Stock

As of September 30, 2017 and December 31, 2016, we had 195,000,000 shares of common stock, $0.01 cent par value per share, authorized under our Restated Certificate of Incorporation, of which 94,513,473 shares were issued and 87,326,952 shares were outstanding at September 30, 2017; 94,437,418 shares were issued and 87,250,897 shares were outstanding at December 31, 2016.

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 2011, our Board of Directors approved a $60,000 common stock repurchase program which was expanded in 2015 to $130,000. Through September 30, 2017 we had repurchased 7,186,521 shares of common stock for an aggregate purchase price of $86,276. We have made no share repurchases since April 2015 and we have $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 and we use an average cost method for determining the cost for reissued treasury shares. The difference between the cost of the shares and the reissuance price is added to or deducted from additional paid-in capital.

Preferred Stock

As of September 30, 2017 and December 31, 2016 we had 5,000,000 shares of preferred stock, $0.01 cent par value per share, authorized under our Restated Certificate of Incorporation. In 2008, we issued 160,000 shares of our Series A Convertible Preferred Stock, all of which are held by Glencore, and at September 30, 2017 and December 31, 2016, 75,299 and 75,625 shares were 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 of preferred to common shares is 100 shares of common for each share of preferred stock. Our Series A Convertible Preferred Stock has a par value of $0.01 per share.

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, liquidation 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.

The Common and Preferred Stock Activity table below contains additional information about preferred stock conversions during the nine months ended September 30, 2017 and 2016.



Common and Preferred Stock Activity:	Preferred stock		Common stock

Ending balance as of September 30, 2016	76,378		7,186,521	87,075,587


6.	Income taxes

We recorded income tax expense of $3,321 for the three months ended September 30, 2017 and an income tax benefit of $848 for the three months ended September 30, 2016 which primarily consisted of foreign income taxes. For the nine months ended September 30, 2017 we recorded income tax expense of $4,465 and for the nine months ended September 30, 2016 we recorded an income tax benefit of $3,237.

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, causes a significant variation in the typical relationship between income tax expense and pretax accounting income.

As of September 30, 2017, 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.

8.	Debt



	September 30, 2017		December 31, 2016
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 $1,964 and $2,301, respectively, interest payable semiannually	248,036		247,699
Total	$	255,851	$	255,514


(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, 2017 was 1.14%.

U.S. Revolving Credit Facility

We and certain of our direct and indirect domestic 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 $150,000 in the aggregate, including up to $110,000 under a letter of credit sub-facility (the "U.S. revolving credit facility"). Our U.S. revolving credit facility matures in June 2020. 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, inventory and qualified cash deposits of the borrowers which meet the eligibility criteria.

Status of our U.S. revolving credit facility:



	September 30, 2017
Credit facility maximum amount	$	150,000
Borrowing availability	125,351
Outstanding letters of credit issued	38,742
Outstanding borrowings	—
Borrowing availability, net of outstanding letters of credit and borrowings	86,609

Iceland Revolving Credit Facility

We have also entered into, through our wholly-owned subsidiary Nordural Grundartangi ehf, a $50,000 revolving credit facility, dated November 27, 2013 (the "Iceland revolving credit facility"). The Iceland revolving credit facility expires on November 27, 2018. 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.

Status of our Iceland revolving credit facility:



	September 30, 2017

7.5% Notes due 2021

General. On June 4, 2013, we issued $250,000 of our 7.5% Notes due June 1, 2021 (the "2021 Notes") in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended. The 2021 Notes were issued at a discount and bear interest at the rate of 7.5% per annum on the principal amount, payable semi-annually in arrears in cash on June 1st and December 1st of each year.

Fair Value. Fair value for our 2021 Notes was based on the latest trading data available and was $255,348 and $234,220, as of September 30, 2017 and December 31, 2016, respectively. 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.


9.	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 $1,154 and $998 at September 30, 2017 and December 31, 2016, respectively. All accrued amounts have been recorded without giving effect to any possible future recoveries. Costs for ongoing environmental compliance, including maintenance and monitoring are expensed as incurred.

Vernon

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 was stayed by the court in 2008 to allow for the remediation of environmental areas at the site. On June 30, 2016 the court ordered the stay lifted and reopened the case. 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. Through September 30, 2017, our affiliate, Virgin Islands Alumina Corporation LLC, has 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.

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 possible 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 condition, results of operations or liquidity. However, because of the nature and inherent uncertainties of litigation, should the 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 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 ("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. Under the terms of the settlement agreement, CAWV agreed to make payments into a trust for the benefit of the CAWV Retirees in the aggregate amount of $23,000 over the course of 10 years. Upon approval of the settlement, we paid $5,000 to the aforementioned trust in September 2017 and recognized a gain of $5,500 to arrive at the net present value of the $12,500 liability recorded in accrued and other current liabilities as well as other liabilities, as of September 30, 2017. CAWV has agreed to pay the remaining amounts under the settlement agreement in annual increments of $2,000 for nine years.

PBGC Settlement

In 2013, we entered into a settlement agreement with the Pension Benefit Guarantee Corporation ("PBGC") regarding an alleged "cessation of operations" at our Ravenswood facility. Pursuant to the terms of the agreement, we agreed to make additional contributions (above any minimum required contributions) to our defined benefit pension plans totaling approximately $17,400. Under certain circumstances, in periods of lower primary aluminum prices relative to our cost of operations, we are able to defer one or more of these payments provided that we provide the PBGC with acceptable security for such deferred payments. We made contributions pursuant to this agreement of $1,100 in 2015 and $6,700 in 2013. We did not make any contributions in 2014, 2016 or the nine months ended September 30, 2017. We have elected to defer certain payments under the PBGC agreement and have provided the PBGC with the appropriate security. The remaining contributions under this agreement are approximately $9,600.

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 2019, 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.

As of September 30, 2017, we had an open position of 19,590 tonnes related to LME forward financial sales contracts, 18,240 tonnes of which are with Glencore, to fix the forward LME price (the “Forward Financial Sales Contracts”). Of these Forward Financial Sales Contracts, 16,500 tonnes settle monthly, on a ratable basis, through December 31, 2017, with the remainder expected to settle between November 1, 2019 and December 31, 2020. We also have financial contracts with Glencore to offset fixed price sales arrangements with certain of our customers (the “fixed for floating swaps”) to remain exposed to the LME price. As of September 30, 2017, we had an open position related to such arrangements of 6,207 tonnes settling at various dates through December 2018.

We have also entered into financial contracts to fix the forward price of approximately 4% of power purchases at Grundartangi for the period November 1, 2019 through December 31, 2020 (the “power price swaps”). The power price swaps are not designated as cash flow hedges. As of September 30, 2017, we had an open position of 256,200 MWh related to the power price swaps.

As of September 30, 2017, we had a derivative asset and liability of $1,469 and $7,715, respectively, in the consolidated balance sheets. We recognized losses of $3,888 and $17,068 related to our derivative instruments during the three and nine months ended September 30, 2017, respectively, in the consolidated statements of operations, substantially all of which related to transactions with Glencore. The impact of the derivative instruments on the consolidated balance sheets and consolidated statements of operations was not material for the corresponding prior periods presented.

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 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 flow from operations are as follows:


•	the price of primary aluminum, which is based on the LME, or other exchanges, regional delivery premiums and any value-added product premiums;


•	the cost of goods sold, the principal components of which are electrical power, alumina, carbon products and labor, which in aggregate exceed 75% of our cost of goods sold; and


•	our production and shipment volume.

Results of Operations

The following discussion for both the three and nine months ended September 30, 2017 reflects Grundartangi and Sebree operating at full capacity and Hawesville and Mt. Holly operating at approximately 40% and 50% of full capacity, respectively.

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 two-month lag basis reflecting contractual terms with our customers.

Electrical power, alumina, carbon anodes and labor are the principal components of our cost of goods sold. These components together represented over 75% of our cost of goods sold for the year ended December 31, 2016. 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 (in millions)	2017		2016		$ Difference
Three months ended September 30,	$	400.6	$	333.7	$	66.9
Nine months ended September 30,	$	1,155.2	$	979.3	$	175.9

Net sales for the three months ended September 30, 2017 improved $66.9 million compared to the same period in 2016 driven primarily by higher price realizations of $63.5 million and favorable volume/mix of $3.4 million.

Net sales for the nine months ended September 30, 2017 improved $175.9 million compared to the same period in 2016 driven primarily by higher price realizations of $175.5 million and favorable volume/mix of $0.4 million.



Gross profit (loss) (in millions)	2017		2016			$ Difference
Three months ended September 30,	$	41.4	$	(17.6	)	$	59.0
Nine months ended September 30,	$	80.7	$	(16.1	)	$	96.8

Gross profit for the three months ended September 30, 2017 improved $59.0 million compared to the same period in 2016 driven primarily by higher price realizations of $63.5 million, of which $59.8 million was attributable to higher LME, as well as favorable operating expense and volume/mix of $2.7 million and $2.6 million, respectively. The improvement was partially offset by unfavorable raw material prices of $7.4 million, unfavorable power prices of $1.8 million and unfavorable other of $0.6 million.

Gross profit for the nine months ended September 30, 2017 improved $96.8 million compared to the same period in 2016 driven primarily by higher price realizations of $175.5 million, of which $171.8 million was due to higher LME, and favorable operating expense of $8.1 million. This favorability was partially offset by unfavorable raw material prices of $49.9 million, unfavorable power prices of $30.6 million, unfavorable volume/mix of $6.0 million and other unfavorability of $0.3 million.



Selling, general and administrative expenses (in millions)	2017		2016		$ Difference
Three months ended September 30,	$	14.0	$	9.7	$	4.3
Nine months ended September 30,	$	34.0	$	29.3	$	4.7

Selling, general and administrative expenses for both the three and nine months ended September 30, 2017 were higher by $4.3 million and $4.7 million, respectively, compared to the same periods in 2016. The increase was primarily due to higher professional fees incurred during the current quarter.



Net gain (loss) on forward and derivative contracts (in millions)	2017			2016		$ Difference
Three months ended September 30,	$	(3.9	)	$	1.3	$	(5.2	)
Nine months ended September 30,	$	(17.1	)	$	3.0	$	(20.1	)

For the three months ended September 30, 2017, we recorded unrealized gains of $1.3 million and realized losses of $5.2 million for a net loss of $3.9 million. For the nine months ended September 30, 2017, we recorded unrealized and realized losses of $5.9 million and $11.2 million, respectively, for a total loss of $17.1 million. The period to period changes in net gain (loss) on forward and derivative contracts was primarily due to the impact of LME market price increases on the fair value of our forward and derivative contracts. See Note 13 Derivatives to the consolidated financial statements included herein for additional information.



Income tax (expense) benefit (in millions)	2017			2016		$ Difference
Three months ended September 30,	$	(3.3	)	$	0.8	$	(4.1	)
Nine months ended September 30,	$	(4.5	)	$	3.2	$	(7.7	)

We have a valuation allowance against all of our U.S. and certain foreign deferred tax assets. The period to period differences in income tax (expense) benefit are primarily due to the change in earnings at our foreign entities that are not subject to a valuation allowance while the entities that are subject to a valuation allowance are unable to recognize a tax benefit for their losses. See Note 6 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), debt service requirements, the funding of capital expenditures, investments in our growth activities and in related businesses, working capital and other general corporate requirements.

Available Cash

Our consolidated cash and cash equivalents balance at September 30, 2017 was $174.2 million compared to $132.4 million at December 31, 2016.

Sources and Uses of Cash

Our statements of cash flows for the nine months ended September 30, 2017 and 2016 are summarized below:



	Nine months ended September 30,
	2017			2016
	(in thousands)
Net cash provided by operating activities	$	50,667		$	15,327
Net cash used in investing activities	(9,138		)	(13,127		)
Net cash provided by financing activities	281			—
Change in cash and cash equivalents	$	41,810		$	2,200

Net cash provided by operating activities for the nine months ended September 30, 2017 and 2016 was $50.7 million and $15.3 million, respectively. The favorable change in cash provided by operating activities was driven by year to date net income compared to a net loss in the prior year, partially offset by a $26.2 million increase in trade accounts receivable in 2017

as compared to 2016 resulting from longer payment terms as we increased direct sales to end-users and a $22.8 million increase in inventories due to higher raw material costs.

Net cash used in investing activities for the nine months ended September 30, 2017 and 2016 was $9.1 million and $13.1 million, respectively. The change in cash used in investing activities was driven primarily by proceeds of $13.6 million received in January 2017 from the sale of our Ravenswood facility, partially offset by an increase in capital expenditures in 2017 of $10.5 million over the prior year period.

Net cash provided by financing activities for the nine months ended September 30, 2017 and 2016 was immaterial.

Availability Under Our Credit Facilities

We and certain of our direct and indirect subsidiaries are party to a senior secured revolving credit facility for our U.S. operations, 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 million under a letter of credit sub-facility. We have also entered into, through our wholly-owned subsidiary Nordural Grundartangi ehf, a $50 million revolving credit facility, dated November 27, 2013. Our U.S. revolving credit facility matures in June 2020 and our Iceland revolving credit facility matures in November 2018.

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. Curtailments of production capacity decrease our borrowing base by reducing our accounts receivable and inventory balances. As of September 30, 2017, our credit facilities had $136.6 million of net availability, after consideration of our outstanding 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. The borrowings and repayments under our credit facilities for the nine months ended September 30, 2017 were related to routine banking fees.

As of September 30, 2017, we had $38.7 million of letters of credit outstanding under our U.S. revolving credit facility with 57% related to our domestic power commitments and the remainder securing certain debt and workers' compensation commitments.

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., a springing financial covenant that requires us 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 $15.0 million. As of September 30, 2017, our fixed charge coverage ratio was less than 1.1 to 1.0; however, our availability under the U.S. credit facility as of September 30, 2017 was $86.6 million. Our Icelandic credit facility also contains a covenant that requires Grundartangi to maintain a minimum equity ratio. As of September 30, 2017, we were in compliance with all such covenants.

Senior Secured Notes

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

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, 2017, the principal and accrued interest for the E.ON contingent obligation was $22.1 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, 2017 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.

Employee Benefit Plan Contributions

In April 2013, we entered into a settlement agreement with the PBGC regarding an alleged "cessation of operations" at our Ravenswood facility as a result of the curtailment of operations at the facility and, pursuant to the agreement, we agreed to

make additional contributions (above any minimum required contributions) to our defined benefit pension plans totaling approximately $17.4 million. The agreement permits us to defer payments during periods of lower primary aluminum prices relative to our cost of operations. We remeasure aluminum prices against our cost of operations on an annual basis based on our fourth quarter results. To the extent that we elect to defer one or more of these payments, we are required to provide the PBGC with acceptable security for any such deferred payments. We made contributions pursuant to this agreement of $1.1 million in 2015 and $6.7 million in 2013. We did not make any contributions during 2014, 2016 and the nine month period ended September 30, 2017. The remaining contributions under this agreement are approximately $9.6 million.

Other items

In 2011, our Board of Directors approved a $60 million common stock repurchase program which was expanded in 2015 to $130 million. Through September 30, 2017, we expended $86.3 million under the program and repurchased 7.2 million common shares. There have been no share repurchases since April 2015 and as of September 30, 2017, 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.

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 such 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 9 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 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, 2017 were $23.6 million. We estimate our total capital spending in 2017 will be approximately $30.0 million, primarily related to our ongoing maintenance and investment projects at our smelters.

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. As of September 30, 2017, we had open LME forward financial sales contracts to fix the forward LME price of 19,590 tonnes of primary aluminum. Of these, 17 tonnes settle monthly, on a ratable basis, through December 31, 2017, with the remaining

expected to settle ratably between November 1, 2019 and December 31, 2020. At September 30, 2017 we recorded a liability of $7.7 million to reflect the fair value for the forward financial sales contracts.

From time to time, we enter into financial contracts to offset fixed price sales arrangements with certain of our customers to remain exposed to the LME price. As of September 30, 2017, we had open positions related to such arrangements of 6,207 tonnes of primary aluminum which settle on various dates up to and including December 2018. These financial contracts have equal and offsetting asset and liability positions, resulting in a net fair value of zero.

We are also exposed to price risk for alumina which is a large component of our cost of goods sold. We may from time to time 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). Currently, all of our alumina contracts are priced based on a published alumina index.

Our risk management activities do not include any trading or speculative transactions.

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. 75% of Mt. Holly's electric power requirements were supplied at rates based on natural gas prices. See Note 9 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 2023 through 2036 (subject to extension), primarily provide power at LME-based variable rates. However, Grundartangi has agreed to pay a portion of its power from November 1, 2019 through December 31, 2023 at prices linked to the Nord Pool power market.

Electrical Power Price Sensitivity

With the movement toward market-based power supply agreements, we have increased our electrical power price risk for our operations, whether due to fluctuations in the price of power available on the MISO or Nord Pool power markets or the price of natural gas. 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 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.

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. During 2017, we entered into financial contracts to fix the forward price of approximately 4% of power purchases at Grundartangi for the period November 1, 2019 through December 31, 2020 (the “power price swaps”). As of September 30, 2017, we had an open position of 256,200 MWh related to the power price swaps and the fair value was immaterial.

The consumption shown in the table below is at normal capacity levels and does not reflect partial production curtailments.



Electrical power price sensitivity by location:
	Hawesville		Sebree		Mt. Holly		Total
Expected average load (in megawatts ("MW"))	482		385		400		1,267
Quarterly estimated electrical power usage (in megawatt hours ("MWh"))	1,055,580		843,150		876,000		2,774,730
Quarterly cost impact of an increase or decrease of $1 per MWh (in thousands)	$	1,100	$	800	$	900	$	2,800
Annual expected electrical power usage (in MWh)	4,222,320		3,372,600		3,504,000		11,098,920
Annual cost impact of an increase or decrease of $1 per MWh (in thousands)	$	4,200	$	3,400	$	3,500	$	11,100

The operations at Hawesville and Mt. Holly, however, are currently running at approximately 40% and 50% of full capacity, respectively.

Foreign Currency

We are exposed to foreign currency risk due to fluctuations in the value of the U.S. dollar as compared to the Iceland krona ("ISK"), the euro, the Chinese renminbi and other currencies. Grundartangi’s labor costs, part of its maintenance costs and other local services are denominated in ISK and a portion of its anode costs are denominated in euros and Chinese renminbi. We have deposits denominated in ISK in Icelandic banks; in addition, 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. As a result, an increase or decrease in the value of those currencies relative to the U.S. dollar would affect Grundartangi’s operating margins.

We may manage our exposure by entering into foreign currency forward contracts or option contracts for forecasted transactions and projected cash flows for foreign currencies in future periods. As of September 30, 2017, we had no foreign currency forward contracts outstanding.

Natural Economic Hedges

Any analysis of our exposure to the commodity price of aluminum should consider the impact of natural hedges provided by certain contracts that contain pricing indexed to the LME price for primary aluminum. 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 4. Controls and Procedures.

a. Evaluation of Disclosure Controls and Procedures

As of September 30, 2017, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Principal Financial Officer, of the effectiveness of our disclosure controls and procedures. Based upon that evaluation, our management, including the Chief Executive Officer and Principal Financial Officer, concluded that our disclosure controls and procedures were effective as of September 30, 2017.

b. Changes in Internal Control over Financial Reporting

During the three months ended September 30, 2017, 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.

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 condition, results of operations or liquidity. For information regarding legal proceedings pending against us at September 30, 2017, refer to Note 9 Commitments and contingencies to the consolidated financial statements included herein.

Item 1A. Risk Factors.

The following is an update to the similarly named risk factor set forth in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016. Other than the following update, there have been no material changes to 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, 2016. You should carefully consider the risk factor 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.

Unpredictable events, including natural disasters, dangerous weather conditions, river conditions and political unrest, may adversely affect our ability to conduct business.

We receive a significant portion of our revenues from operations in areas that have heightened risk of natural disasters, including Iceland. Iceland suffered several natural disasters and extreme weather events in 2010, 2011, 2012, 2014 and 2016, including significant volcanic eruptions and earthquakes. Power is supplied to our Grundartangi smelter from hydroelectric and geothermal sources. Lack of sufficient rain that leads to low water levels in the reservoirs could lead to power curtailments which impact our production.Future unpredictable events, including natural disasters, dangerous weather conditions and political unrest, may adversely affect our ability to conduct business by causing disruptions in Icelandic, Chinese, Dutch, U.S. or global economic conditions, inflicting loss of life, damaging property and requiring substantial capital expenditures and operating expenses to remediate damage and restore operations at our production facilities.

In addition, we accept delivery of necessary raw materials transported using public infrastructure such as river systems and seaports. Deterioration of such infrastructure and/or other adverse conditions could result in transportation delays or interruptions and increased costs, as occurred during the third quarter of 2017 when lock closures on the Ohio River impacted our alumina supply and forced us to find alternative means to transport alumina to our Kentucky operations at increased cost. Any delays in the delivery of raw materials necessary for our production impact our ability to operate our plants and could have a material adverse effect on our business, financial condition or results of operation.

Future unpredictable events, including natural disasters, dangerous weather conditions and political unrest, may adversely affect our ability to conduct business by causing disruptions in Icelandic, Chinese, Dutch, U.S. or global economic conditions, inflicting loss of life, damaging property and requiring substantial capital expenditures and operating expenses to remediate damage and restore operations at our production facilities.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

None.

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, 2017, non-U.S. affiliates of the largest stockholder of the Company (“the non-U.S. Stockholder Affiliates”) entered into sales and purchase contracts for agricultural products, metals, minerals, and energy 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 $144 million for the quarter ended September 30, 2017.

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.

In compliance with applicable economic sanctions and in conformity with U.S. secondary sanctions, the non-U.S. Stockholder Affiliates expect to continue to engage in similar activities in the future.

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, 2017 that requires disclosure in this report under Section 13(r) of the Exchange Act.
