Commitments and Contingencies Disclosure [Abstract] |
Commitments and contingencies | Commitments and contingencies Environmental Contingencies Based upon all available information, we believe our current environmental liabilities do not have, and are not likely to have, a material adverse effect on our financial condition, results of operations or liquidity. Because of the issues and uncertainties described below and the inability to predict the requirements of future environmental laws, there can be no assurance that future capital expenditures and costs for environmental compliance at currently or formerly owned or operated properties will not result in liabilities which may have a material adverse effect. It is our policy to accrue for costs associated with environmental assessments and remedial efforts when it becomes probable that a liability has been incurred and the costs can be reasonably estimated. The aggregate environmental-related accrued liabilities were $1,113 and $999 at March 31, 2014 and December 31, 2013, respectively. All accrued amounts have been recorded without giving effect to any possible future recoveries. With respect to costs for ongoing environmental compliance, including maintenance and monitoring, such costs are expensed as incurred. Century Aluminum of West Virginia ("CAWV") continues to perform monitoring activities at our Ravenswood, West Virginia facility pursuant to an order issued by the United States Environmental Protection Agency (the "EPA") in 1994 (the "3008(h) Order"). CAWV also conducted a RCRA facility investigation ("RFI") under the 3008(h) Order evaluating other areas at Ravenswood that may have contamination requiring remediation. The RFI has been approved by appropriate agencies. CAWV has completed interim remediation measures at two sites identified in the RFI, and we believe no further remediation will be required. A Corrective Measures Study, which formally documents the conclusion of these activities, has been submitted to the EPA and a final order has been completed and was signed by the EPA in April 2013. Under the order, CAWV's responsibilities going forward include monitoring specific wells as well as restricting access to certain parts of the site. Prior to our purchase of Hawesville, the EPA issued a final Record of Decision ("ROD") under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"). By agreement, Southwire Company ("Southwire"), the former owner and operator, is to perform all obligations under the ROD. CAKY has agreed to operate and maintain the ground water treatment system required under the ROD on behalf of Southwire, and Southwire will reimburse CAKY for any expense that exceeds $400 annually. The groundwater treatment system ceased operations in May 2010 and was decommissioned and removed from site in 2012. Quarterly monitoring of specific wells is ongoing. In July 2006, we were named as a defendant, together with certain affiliates of Alcan Inc., in a lawsuit brought by Alcoa Inc. seeking to determine responsibility for certain environmental indemnity obligations related to the sale of a cast aluminum plate manufacturing facility located in Vernon, California, which we purchased from Alcoa Inc. in December 1998, and sold to Alcan Rolled Products-Ravenswood LLC in July 1999. The complaint also seeks costs and attorney fees. The matter is in a preliminary stage, and we cannot predict the ultimate outcome of this action or estimate a range of possible losses related to this matter at this time. Matters relating to the St. Croix Alumina Refining Facility We are a party to an EPA Administrative Order on Consent (the "Order") pursuant to which other past and present owners of an alumina refining facility at St. Croix, Virgin Islands (the "St. Croix Alumina Refinery") have agreed to carry out a Hydrocarbon Recovery Plan to remove and manage hydrocarbons floating on groundwater underlying the facility. Pursuant to the Hydrocarbon Recovery Plan, recovered hydrocarbons and groundwater are delivered to the adjacent petroleum refinery where they are received and managed. In connection with the sale of the facility by Lockheed Martin Corporation ("Lockheed") to one of our affiliates, Virgin Islands Alumina Corporation ("Vialco"), in 1989, Lockheed, Vialco and Century entered into the Lockheed-Vialco Asset Purchase Agreement. The indemnity provisions contained in the Lockheed-Vialco Asset Purchase Agreement allocate responsibility for certain environmental matters. Lockheed has tendered indemnity and defense of the above matter to Vialco. We have likewise tendered indemnity to Lockheed. Through March 31, 2014, we have expended approximately $1,033 on the Hydrocarbon Recovery Plan. At this time, we are not able to estimate the amount of any future potential payments under this indemnification to comply with the Order, but we do not anticipate that any such amounts will have a material adverse effect on our financial condition, results of operations or liquidity, regardless of the final outcome. In May 2005, we and Vialco were among several defendants listed in a lawsuit filed by the Commissioner of the Department of Planning and Natural Resources ("DPNR"), in his capacity as Trustee for Natural Resources of the United States Virgin Islands. The complaint alleges damages to natural resources caused by alleged releases from the St. Croix Alumina Refinery and the adjacent petroleum refinery. The primary cause of action is pursuant to the natural resource damage provisions of CERCLA, but various ancillary Territorial law causes of action were included as well. We and Lockheed have each tendered indemnity and defense of the case to the other pursuant to the terms of the Lockheed-Vialco Asset Purchase Agreement. The complaint seeks unspecified monetary damages, costs and attorney fees. In November 2011, the court granted a motion by Century, dismissing Century from the case. Vialco, however, remains a defendant in this case and has asserted factual and affirmative defenses. The trial is currently scheduled to commence on June 24, 2014. In December 2006, Vialco and the succeeding owners of the St. Croix Alumina Refinery were named as defendants in a separate lawsuit filed by the Commissioner of the DPNR. The complaint alleges the defendants failed to take certain actions specified in a Coastal Zone management permit issued to Vialco in October 1994, and alleges violations of territorial water pollution control laws during the various defendants’ periods of ownership. The complaint seeks statutory and other unspecified monetary penalties for the alleged violations. On March 19, 2012, the plaintiff filed a motion to dismiss the settling defendants in the DPNR case described above from this action. On May 9, 2012, the court granted plaintiff's motion to dismiss leaving Vialco as the only remaining defendant in this action. No additional developments have occurred on this case since March 2012. In May 2009, St. Croix Renaissance Group, L.L.L.P. ("SCRG") filed a third-party complaint for contribution and other relief against several third-party defendants, including Century and Vialco, relating to a lawsuit filed against SCRG seeking recovery of response costs relating to the aforementioned DPNR CERCLA matter. In February 2011, the court granted a motion by Century, dismissing Century from the case. In March 2011, the court granted the remaining defendants’, including Vialco’s, motion for summary judgment, dismissing the case. The plaintiff filed a notice of appeal with the Third Circuit Court of Appeals in May 2011. On June 5, 2013, the Third Circuit Court of Appeals reversed the lower court's ruling, holding that plaintiff's expenditures of funds may be found as recoverable response costs incurred by the government entitling plaintiffs to recover future response costs. Vialco remains the only Century entity in the litigation. No further developments have occurred. In December 2010, Century was among several defendants listed in a lawsuit filed by plaintiffs who either worked, resided or owned property in the area downwind from the St. Croix Alumina Refinery. In March 2011, Century was also named a defendant in a nearly identical suit brought by certain additional plaintiffs. The plaintiffs in both suits allege damages caused by the presence of red mud and other particulates coming from the alumina facility and are seeking unspecified monetary damages, costs and attorney fees as well as certain injunctive relief. We have tendered indemnity and defense to St. Croix Alumina LLC and Alcoa Alumina & Chemical LLC under the terms of an acquisition agreement relating to the facility and have filed motions to dismiss plaintiffs’ claims, but the court has not yet ruled on the motions. At this time, it is not practicable to predict the ultimate outcome of or to estimate a range of possible losses for any of the foregoing actions relating to the St. Croix Alumina Refinery. 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, shareholder, safety and health matters. In evaluating whether to accrue for losses associated with legal contingencies, it is our policy to take into consideration factors such as the facts and circumstances asserted, our historical experience with contingencies of a similar nature, the likelihood of our prevailing and the severity of any potential loss. For some matters, no accrual is established because we have assessed our risk of loss to be remote. Where the risk of loss is probable and the amount of the loss can be reasonably estimated, we record an accrual, either on an individual basis or with respect to a group of matters involving similar claims, based on the factors set forth above. When we have assessed that a loss associated with legal contingencies is reasonably possible, we determine if estimates of possible losses or ranges of possible losses are in excess of related accrued liabilities, if any. Based on current knowledge, management has ascertained estimates for losses that are reasonably possible and management does not believe that any reasonably possible outcomes in excess of our accruals, if any, either individually or in aggregate, would be material to our financial condition, results of operations, or liquidity. We reevaluate and update our assessments and accruals as matters progress over time. In December 2013, we received a ruling in the arbitration of a lawsuit filed by our former Chief Executive Officer, Logan Kruger. In the lawsuit, Mr. Kruger alleged that Century had breached the employment and severance protection agreements between Century and Mr. Kruger and that Century was obligated to make various severance payments to him in excess of $20,000. In its ruling, the arbitration panel awarded Mr. Kruger approximately $8,700 in severance payments, plus accrued interest, but rejected Mr. Kruger’s claims for further severance payments and held that Mr. Kruger had forfeited all of his outstanding incentive awards upon his resignation from Century. We recorded a net charge of approximately $8,400 in selling, general and administrative expenses for the year ended December 31, 2013. In April 2013, our subsidiary Nordural Grundartangi ehf received a ruling in an arbitration case involving two of its power suppliers, HS Orka hf ("HS") and Orkuveita Reykjavikur ("OR"). Under the arbitration award, Nordural Grundartangi ehf is restricted from reducing power under its existing power contracts with HS and OR in order to take power under a separate power contract with OR originally intended to be used at Helguvik. Nordural Grundartangi ehf remains entitled to take power under the OR Helguvik contract to the extent that its power needs exceed the amount of power provided under its existing power contracts. As part of the award, the tribunal awarded HS damages and Nordural Grundartangi ehf paid $1,470 to HS in full satisfaction of such award. The tribunal ordered each party to pay its own legal fees and costs. While no damages were awarded to OR as part of the arbitration, OR has subsequently alleged damages against Nordural Grundartangi ehf. We intend to defend ourselves against these claims and expect that any possible losses incurred in the ultimate resolution of this dispute in excess of the amount accrued will not be material. Ravenswood Retiree Medical Benefits changes In November 2009, CAWV filed a class action complaint for declaratory judgment against the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union ("USWA"), the USWA’s local and certain CAWV retirees, individually and as class representatives, seeking a declaration of CAWV’s rights to modify/terminate retiree medical benefits. Later in November 2009, the USWA and representatives of a retiree class filed a separate suit against CAWV, Century Aluminum Company, Century Aluminum Master Welfare Benefit Plan, and various John Does with respect to the foregoing. These actions, entitled Dewhurst, et al. v. Century Aluminum Co., et al., and Century Aluminum of West Virginia, Inc. v. United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union, AFL-CIO/CLC, et al., have been consolidated and venue has been set in the District Court for the Southern District of West Virginia. In January 2010, the USWA filed a motion for preliminary injunction to prevent us from implementing any modifications to the retiree medical benefits while these lawsuits are pending, which was dismissed by the trial court, and affirmed upon appeal. The case in chief is currently proceeding in the trial court. PBGC Settlement In June 2011, the Pension Benefit Guaranty Corporation (the "PBGC") informed us that it believed a "cessation of operations" under ERISA had occurred at our Ravenswood facility as a result of the curtailment of operations at the facility. Although we disagree that a "cessation of operations" occurred, we entered into a settlement agreement with the PBGC in April 2013 to resolve the matter. Pursuant to the terms of the agreement, we will make additional contributions (above any minimum required contributions) to our defined benefit pension plans totaling approximately $17,400 over the term of the agreement. During 2013, we made contributions pursuant to this agreement of approximately $6,700. Under certain circumstances, in periods of lower primary aluminum prices relative to our cost of operations, we may defer one or more of these payments, but we would be required to provide the PBGC with acceptable security for any deferred payments. In the first quarter of 2014, we elected to defer contributions under the PBGC agreement and have provided the PBGC with the appropriate security. Power Commitments Hawesville In August 2012, CAKY issued a 12-month notice to terminate its long-term power supply arrangement with Kenergy. Pursuant to the termination notice, the Hawesville Power Agreement terminated on August 20, 2013. The Kentucky Public Service Commission ("KPSC") approved a new power supply agreement with Kenergy and Big Rivers which provides market-based power to the Hawesville smelter, effective August 20, 2013. Under the arrangement, the power companies purchase power on the open market and pass it through to Hawesville at Midcontinent Independent System Operator ("MISO") pricing plus transmission and other costs incurred by them. In connection with the new power arrangement, CAKY has received approval from applicable regional transmission organizations and regulatory bodies regarding grid stability and energy import capability. Sebree In January 2013, Sebree (then still owned by RTA) issued a 12-month notice to terminate its long-term power supply agreement (the "Sebree Power Agreement") with Kenergy. Pursuant to the termination notice, the Sebree Power Agreement terminated on January 31, 2014. The KPSC approved a new power supply arrangement with Kenergy and Big Rivers which provides market-based power to the Sebree smelter, effective February 1, 2014. Similar to the arrangement at Hawesville, the power companies purchase power on the open market and pass it through to Sebree at MISO pricing plus transmission and other costs incurred by them. Mt. Holly Mt. Holly has a power purchase agreement (the "Santee Cooper Agreement") with the South Carolina Public Service Authority ("Santee Cooper") with a term through December 2015. The Santee Cooper Agreement provides power for Mt. Holly’s full production capacity requirements at prices based on published rate schedules (which are subject to change), with adjustments for fuel prices and other items. The Santee Cooper Agreement restricts Mt. Holly’s ability to reduce its power consumption (or the associated payment obligations) below contracted levels and to terminate the agreement, unless, in each case, the LME falls below certain negotiated levels. In 2012, Mt. Holly and Santee Cooper amended the terms of the Santee Cooper Agreement in order to allow Mt. Holly to receive all or a portion of Mt. Holly's supplemental power requirements from an off-system natural gas-fired power generation facility (the "off-system facility"). The energy charge for supplemental power from the off-system facility is based, among other factors, on the cost of natural gas rather than Santee Cooper's system average fuel costs, which are primarily coal-based. The amended power agreement provides that Mt. Holly may continue to receive its supplemental power requirements from the off-system facility through December 31, 2015. We are currently in discussions with Santee Cooper and other parties regarding power arrangements for Mt. Holly following December 31, 2015. The deadline to give notice to reduce the contract demand to zero effective December 31, 2015 is June 30, 2014. Ravenswood CAWV has a power purchase agreement (the "APCo Agreement") with the Appalachian Power Company ("APCo"). CAWV currently purchases a limited amount of power under the APCo Agreement as necessary to maintain its Ravenswood smelter, which is presently curtailed. Power is supplied under the APCo Agreement at prices set forth in published tariffs (which are subject to change), with certain adjustments. Grundartangi Nordural Grundartangi ehf has power purchase agreements with HS, Landsvirkjun and OR to provide power to its Grundartangi smelter. These power purchase agreements, which will expire on various dates from 2019 through 2036, provide power at LME-based variable rates. Each power purchase agreement contains take-or-pay obligations with respect to a significant percentage of the total committed and available power under such agreement. In the fourth quarter of 2011, an additional 47.5 MW of power became available under a power purchase agreement with OR. This power can be used at either Grundartangi or Helguvik and is currently being utilized at Grundartangi. In June 2012, Nordural Grundartangi ehf entered into a new supplemental power contract with Landsvirkjun. The supplemental power contract, which will expire in October 2029 (or upon the occurrence of certain earlier events), will provide Nordural Grundartangi ehf with supplemental power, as Nordural Grundartangi ehf may request from time to time, at LME-based variable rates. Nordural Grundartangi ehf has agreed to make certain prepayments to Landsvirkjun for power expected to be used at a later date in connection with the contract, which will reduce the price paid for power at the time of consumption. As of March 31, 2014, these power prepayments totaled approximately $2,000. We expect the amount of the prepayment to continue to grow slowly and we do not expect to realize the benefits from the prepayments in the near term. Helguvik Nordural Helguvik ehf has power purchase agreements with HS and OR to provide power to the Helguvik project. These power purchase agreements provide power at LME-based variable rates and contain take-or-pay obligations with respect to a significant percentage of the total committed and available power under such agreements. The first stage of power under the OR power purchase agreement (approximately 47.5 MW) became available in the fourth quarter of 2011 and is currently being utilized at Grundartangi. No other power is currently available under either power purchase agreement. HS (with respect to all phases) and OR (with respect to all phases other than the first phase) have alleged that certain conditions to the delivery of power under the power purchase agreements have not been satisfied. Nordural Helguvik ehf is in discussions with both HS and OR with respect to such conditions and other matters pertaining to these agreements. Other Commitments and Contingencies Labor Commitments Approximately 73% of our U.S. based work force is represented by the USWA. CAKY’s Hawesville employees represented by the USWA are under a collective bargaining agreement that expires on March 31, 2015. The Sebree employees represented by the USWA are under a collective bargaining agreement that expires on October 28, 2014. In April 2010, Nordural Grundartangi ehf entered into a new labor agreement with the five labor unions representing approximately 82% of Grundartangi’s work force. The labor agreement expires on December 31, 2014. In July 2013, Century Vlissingen entered into a collective labor agreement with Vlissingen employees represented by the Federation for the Metal and Electrical Industry ("FME") which comprise approximately 77% of Vlissingen's work force. The labor agreement expires on May 1, 2015. The labor agreement for CAWV’s Ravenswood plant employees represented by the USWA expired on August 31, 2010.
