Commitments and Contingencies Disclosure [Abstract] |
Contingencies and Commitments | Contingencies and Commitments Contingencies Environmental Matters. Howmet participates in environmental assessments and cleanups at more than 30 locations. These include owned or operating facilities and adjoining properties, previously owned or operating facilities and adjoining properties, and waste sites, including Superfund (Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA")) sites. A liability is recorded for environmental remediation when a cleanup program becomes probable and the costs can be reasonably estimated. As assessments and cleanups proceed, the liability is adjusted based on progress made in determining the extent of remedial actions and related costs. The liability can change substantially due to factors such as the nature and extent of contamination, changes in remedial requirements, and technological changes, among others. The Company's remediation reserve balance was $10 at December 31, 2020 and $8 at December 31, 2019 recorded in Other noncurrent liabilities and deferred credits in the Consolidated Balance Sheet (of which $5 and $3, respectively, were classified as a current liability), and reflects the most probable costs to remediate identified environmental conditions for which costs can be reasonably estimated. Payments related to remediation expenses applied against the reserve were $2 in 2020 and $3 in 2019 and included expenditures currently mandated, as well as those not required by any regulatory authority or third party. Included in annual operating expenses are the recurring costs of managing hazardous substances and environmental programs. These costs are estimated to be less than 1% of Cost of goods sold. The Company previously reported on a remediation project related to the Grasse River, which is adjacent to the Massena West, New York plant site that is now part of Arconic Corporation. Pursuant to the Separation and Distribution Agreement between the Company and Arconic Corporation, dated as of March 31, 2020, Arconic Corporation agreed to assume and indemnify the Company against potential liabilities associated with the Grasse River remediation project. Therefore, the Company will no longer report on the Grasse River matter unless and until some event in the future causes it to become material and reportable. Tax. As pre viously reported, in July 2013, following a Spanish corporate income tax audit covering the 2006 through 2009 tax years, an assessment was received mainly disallowing certain interest deductions claimed by a Spanish consolidated tax group owned by the Company. The Company appealed this assessment to Spain's Central Tax Administrative Court, and subsequently to Spain's National Court, each of which was denied. The Company then appealed the decision to the Supreme Court of Spain. In November 2020, the Supreme Court of Spain rendered a decision in favor of the taxpayer, removing the assessment in its entirety. The decision is final and cannot be further appealed. As a result of the favorable decision, in the fourth quarter of 2020, the Company released an income tax reserve, including interest, of $64 (€54), which was recorded in Provision (benefit) for income taxes in the Consolidated Statement of Operations, that was previously established in the third quarter of 2018. In addition, the Company reversed a combined indemnification receivable of $53 (€45) for Alcoa Corporation's 49% share and Arconic Corporation's 33.66% share of the total reserve, which was recorded in Other expense (income), net in the Consolidated Statement of Operations, that were previously established pursuant to the October 31, 2016 and March 31, 2020 Tax Matters Agreements, respectively. As of the end of 2020, the Company no longer has a balance recorded for this matter. Reynobond PE. Prior to the Arconic Inc. Separation Transaction on April 1, 2020, the Company was known as Arconic Inc. References to “Arconic Inc.” in this “Reynobond PE” section refer to Arconic Inc. only and do not include its subsidiaries, except as otherwise stated. On June 13, 2017, the Grenfell Tower in London, U.K. caught fire resulting in fatalities, injuries and damage. A French subsidiary of Arconic Inc., Arconic Architectural Products SAS ("AAP SAS") (now a subsidiary of Arconic Corporation as a result of the Arconic Inc. Separation Transaction), supplied a product, Reynobond PE, to its customer, a cladding system fabricator, which used the product as one component of the overall cladding system on Grenfell Tower. The fabricator supplied its portion of the cladding system to the façade installer, who then completed and installed the system under the direction of the general contractor. Neither Arconic Inc. nor AAP SAS was involved in the design or installation of the system used at the Grenfell Tower, nor did it have a role in any other aspect of the building’s refurbishment or original design. Regulatory investigations into the overall Grenfell Tower matter are being conducted, including a criminal investigation by the London Metropolitan Police Service (the “Police”), a Public Inquiry by the British government and a consumer protection inquiry by a French public authority. The Public Inquiry was announced by the U.K. Prime Minister on June 15, 2017 and subsequently was authorized to examine the circumstances leading up to and surrounding the Grenfell Tower fire in order to make findings of fact and recommendations to the U.K. Government on matters such as the design, construction and modification of the building, the role of relevant public authorities and contractors, the implications of the fire for the adequacy and enforcement of relevant regulations, arrangements in place for handling emergencies and the handling of concerns from residents, among other things. Hearings for Phase 1 of the Public Inquiry began on May 21, 2018 and concluded on December 12, 2018. Phase 2 hearings of the Public Inquiry began in early 2020, following which a final report will be written and subsequently published. AAP SAS is participating as a Core Participant in the Public Inquiry and is also cooperating with the ongoing parallel investigation by the Police. Arconic Corporation does not sell and Arconic Inc. previously stopped selling the PE product for architectural use on buildings. Given the preliminary nature of these investigations and the uncertainty of potential future litigation, the Company cannot reasonably estimate at this time the likelihood of an unfavorable outcome or the possible loss or range of losses in the event of an unfavorable outcome. Pursuant to the Separation and Distribution Agreement, dated as of March 31, 2020, Arconic Corporation agreed to indemnify the Company for certain liabilities and the Company agreed to indemnify Arconic Corporation for certain liabilities. As a result of the Arconic Inc. Separation Transaction, Arconic Corporation holds the building and construction systems businesses previously held by the Company and AAP SAS is a subsidiary of Arconic Corporation; accordingly, Arconic Corporation has agreed to assume and indemnify the Company against potential liabilities associated with the June 13, 2017 fire at the Grenfell Tower in London, U.K., including the following legal proceedings in which Arconic Inc. and/or its then directors were named as parties: United Kingdom Litigation. On December 23, 2020, claimant groups comprised of survivors and estates of decedents of the Grenfell Tower fire filed claims in the U.K. arising from that fire, against 23 defendants, including Howmet Aerospace Inc., AAP SAS, Arconic Corporation, the Royal Borough of Kensington and Chelsea, the Royal Borough of Kensington and Chelsea Tenant Management Organisation Ltd, the London Fire Commissioner, the UK Home Office, The Ministry of Housing, Communities and Local Government, Rydon Maintenance Ltd, Celotex Ltd, Saint-Gobain Construction Products UK Limited, Kingspan Insulation Limited, Kingspan Group PLC, Studio E Architects Ltd (in liquidation), Harley Facades Ltd, Harley Curtain Wall Limited (in liquidation), CEP Architectural Facades Ltd, Exova (U.K.) Ltd, CS Stokes & Associates Ltd, Artelia Projects UK Limited, Whirlpool UK Appliances Limited, Whirlpool Company Polska Sp.z.o.o. and Whirlpool Corporation. The Company has not yet been served with the claims and, therefore, currently does not have information regarding claimants’ substantive allegations or the relief that claimants seek. Behrens et al. v. Arconic Inc. et al. On June 6, 2019, 247 plaintiffs comprised of survivors and estates of decedents of the Grenfell Tower fire filed a complaint against “Arconic Inc., Alcoa Inc. and Arconic Architectural Products, LLC” (collectively, for purposes of the description of such proceeding, the “Arconic Defendants”), as well as Saint-Gobain Corporation, d/b/a Celotex, and Whirlpool Corporation alleging claims under Pennsylvania state law for products liability and wrongful death related to the fire. In particular, the plaintiffs allege that the Arconic Defendants knowingly supplied a dangerous product ("Reynobond PE") for installation on the Grenfell Tower despite knowing that Reynobond PE was unfit for use above a certain height. Plaintiffs seek monetary damages exceeding $75,000 for each plaintiff. The case was removed to the United States District Court for the Eastern District of Pennsylvania. Defendants moved to dismiss the case on numerous grounds, including forum non conveniens. Defendant Saint-Gobain Corporation was subsequently voluntarily dismissed from the case. On September 16, 2020, the court issued an order granting the remaining defendants’ motion to dismiss on forum non conveniens grounds, subject to certain conditions, determining that the United Kingdom, and not the United States, is the appropriate place for plaintiffs to bring their case. Plaintiffs subsequently filed a motion for reconsideration, which the court denied on November 23, 2020. Plaintiffs are appealing the judgment; the Arconic Defendants are cross-appealing one of the conditions. Howard v. Arconic Inc. et al. A purported class action complaint related to the Grenfell Tower fire was filed on August 11, 2017 in the United States District Court for the Western District of Pennsylvania against Arconic Inc. and Klaus Kleinfeld. A related purported class action complaint was filed in the United States District Court for the Western District of Pennsylvania on September 15, 2017, under the caption Sullivan v. Arconic Inc. et al., against Arconic Inc., three former Arconic Inc. executives, several current and former directors, and certain banks. Howard and Sullivan were subsequently consolidated and the lead plaintiffs in the consolidated purported class action filed a consolidated amended complaint alleging violations of the federal securities laws and seeking, among other things, unspecified compensatory damages and an award of attorney and expert fees and expenses. After the court granted the defendants’ motion to dismiss in full, the lead plaintiffs filed a second amended complaint, and all defendants have moved to dismiss the second amended complaint. Raul v. Albaugh, et al. On June 22, 2018, a derivative complaint was filed nominally on behalf of Arconic Inc. by a purported Arconic Inc. stockholder against the then members of Arconic Inc.’s Board of Directors and Klaus Kleinfeld and Ken Giacobbe, naming Arconic Inc. as a nominal defendant, in the United States District Court for the District of Delaware. The complaint raises similar allegations as the consolidated amended complaint and second amended complaint in Howard, as well as allegations that the defendants improperly authorized the sale of Reynobond PE for unsafe uses, and asserts claims under federal securities laws and Delaware state law. The case has been stayed until the final resolution of the Howard case, the Grenfell Tower Public Inquiry in London, and the investigation by the Police. While there can be no assurances regarding the ultimate resolution of these matters, Arconic Corporation has agreed to assume and indemnify the Company against potential liabilities associated with them. Stockholder Demands. Prior to the Arconic Inc. Separation Transaction, the Board of Directors also received letters, purportedly sent on behalf of stockholders, reciting allegations similar to those made in the federal court lawsuits and demanding that the Board authorize the Company to initiate litigation against members of management, the Board and others. The Board of Directors appointed a Special Litigation Committee of the Board to review, investigate, and make recommendations to the Board regarding the appropriate course of action with respect to these stockholder demand letters. On May 22, 2019, the Special Litigation Committee, following completion of its investigation into the claims demanded in the demand letters, recommended to the Board that it reject the demands to authorize commencement of litigation. On May 28, 2019, the Board adopted the Special Litigation Committee’s findings and recommendations and rejected the demands that it authorize commencement of actions to assert the claims set forth in the demand letters. Lehman Brothers International (Europe) ("LBIE") Claim. On June 26, 2020, LBIE filed formal proceedings against two Firth Rixson entities ("Firth") in the High Court of Justice, Business and Property Courts of England and Wales. The proceedings relate to interest rate swap transactions that Firth entered into with LBIE in 2007 to 2008. In 2008, LBIE commenced insolvency proceedings, an event of default under the agreements, rendering LBIE unable to meet its obligations under the swaps and suspending Firth’s payment obligations. In the Court proceedings, LBIE seeks a declaration that Firth has a contractual obligation to pay the amounts owing to LBIE under the agreements. The parties filed position papers on July 24, 2020 and October 19, 2020 (LBIE) and September 21, 2020 (Firth). A virtual hearing in this matter occurred on January 13 and 14, 2021 in London. A decision is expected in three to six months. The resolution of this matter is not probable as of December 31, 2020. Other. In addition to the matters discussed above, various other lawsuits, claims, and proceedings have been or may be instituted or asserted against the Company, including those pertaining to environmental, product liability, safety and health, employment, tax and antitrust matters. While the amounts claimed in these other matters may be substantial, the ultimate liability cannot currently be determined because of the considerable uncertainties that exist. Therefore, it is possible that the Company’s liquidity or results of operations in a period could be materially affected by one or more of these other matters. However, based on facts currently available, management believes that the disposition of these other matters that are pending or asserted will not have a material adverse effect, individually or in the aggregate, on the results of operations, financial position or cash flows of the Company. Commitments Purchase Obligations. Howmet has entered into purchase commitments for raw materials, energy and other goods and services, which total $210 in 2021, $31 in 2022, $10 in 2023, $8 in 2024, $0 in 2025, and $0 thereafter. Operating Leases. See Note Q for the operating lease future minimum contractual obligations. Guarantees. At December 31, 2020, Howmet had outstanding bank guarantees related to tax matters, outstanding debt, workers’ compensation, environmental obligations, energy contracts, and customs duties, among others. The total amount committed under these guarantees, which expire at various dates between 2021 and 2040 was $44 at December 31, 2020. Pursuant to the Separation and Distribution Agreement between Howmet and Alcoa Corporation, Howmet was required to provide certain guarantees for Alcoa Corporation, which had a fair value of $12 and $9 at December 31, 2020 and 2019, respectively, and were included in Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet. The Company was required to provide a guarantee up to an estimated present value amount of approximately $1,398 and $1,353 at December 31, 2020 and December 31, 2019, respectively. For this guarantee, subject to its provisions, the Company is secondarily liable in the event of a payment default by Alcoa Corporation. The Company currently views the risk of an Alcoa Corporation payment default on its obligations under the contract to be remote. Letters of Credit. The Company has outstanding letters of credit, primarily related to workers’ compensation, environmental obligations and leasing obligations. The total amount committed under these letters of credit, which automatically renew or expire at various dates, mostly in 2021, was $105 at December 31, 2020. Pursuant to the Separation and Distribution Agreements between the Company and Arconic Corporation and between the Company and Alcoa Corporation, the Company is required to retain letters of credit of $53 that had previously been provided related to the Company, Arconic Corporation, and Alcoa Corporation workers’ compensation claims which occurred prior to the respective separation transactions of April 1, 2020 and November 1, 2016. Arconic Corporation and Alcoa Corporation workers’ compensation and letters of credit fees paid by the Company are being proportionally billed to and are being reimbursed by Arconic Corporation and Alcoa Corporation, respectively. Also, the Company was required to provide letters of credit for certain Arconic Corporation environmental obligations and, as a result, the Company has $29 of outstanding letters of credit relating to liabilities (which are included in the $105 in the above paragraph). $13 of these outstanding letters of credit are pending cancellation and will be deemed cancelled once returned by the beneficiary. Arconic Corporation has issued surety bonds to cover these environmental obligations. Arconic Corporation is being billed for these letter of credit fees paid by the Company and will reimburse the Company for any payments made under these letters of credit. Surety Bonds. The Company has outstanding surety bonds primarily related to tax matters, contract performance, workers’ compensation, environmental-related matters, and customs duties. The total amount committed under these surety bonds, which expire and automatically renew at various dates, primarily in 2021, was $43 at December 31, 2020. Pursuant to the Separation and Distribution Agreements between the Company and Arconic Corporation and between the Company and Alcoa Corporation, the Company is required to provide surety bonds of $26 (which are included in the $43 in the above paragraph) that had previously been provided related to the Company, Arconic Corporation, and Alcoa Corporation workers’ compensation claims which occurred prior to the respective separation transactions of April 1, 2020 and November 1, 2016. Arconic Corporation and Alcoa Corporation workers’ compensation claims paid and surety bond fees paid by the Company are being proportionately billed to and are being reimbursed by Arconic Corporation and Alcoa Corporation.
