Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies Disclosure [Text Block]	Note 19 – Commitments and Contingencies The Company previously disclosed in its 2020 Form 10-K that AC Products, Inc. (“ACP”), a wholly owned subsidiary, has been operating a groundwater treatment system to hydraulically contain groundwater contamination emanating from ACP’s site, the principal contaminant of which is perchloroethylene. As of September 30, 2021, ACP believes it is close to meeting the conditions for closure of the groundwater treatment system, but continues to operate this system while in discussions with the relevant authorities. As of September 30, 2021, the Company believes that the range of potential -known liabilities associated with the balance of the ACP water remediation program is approximately $ 0.1 million to $ 1.0 million. The low and high ends of the range are based on the length of operation of the treatment system as determined by groundwater modeling. Costs of operation include the operation and maintenance of the extraction well, groundwater monitoring and program management. The Company previously disclosed in its 2020 Form 10-K that an inactive subsidiary of the Company that was acquired in 1978 sold certain products containing asbestos, primarily on an installed basis, and is among the defendants in numerous lawsuits alleging injury due to exposure to asbestos. During the three and nine months ended September 30, 2021, there have been no significant changes to the facts or circumstances of this previously disclosed matter, aside from on-going claims and routine payments associated with this litigation. Based on a continued analysis of the existing and anticipated future claims against this subsidiary, it is currently projected that the subsidiary’s total liability over the next 50 years for these claims is approximately $ 0.4 million (excluding costs of defense). The Company previously disclosed in its 2020 Form 10-K that it is party to certain environmental matters related to certain domestic and foreign properties currently or previously owned by Houghton. These environmental matters primarily require the Company to perform long-term monitoring as well as operating and maintenance at each of the applicable sites. During the three and nine months ended September 30, 2021, there have been no significant changes to the facts or circumstances of these previously disclosed matters, aside from on-going monitoring and maintenance activities and routine payments associated with each of the sites. The Company continually evaluates its obligations related to such matters, and based on historical costs incurred and projected costs to be incurred over the next 28 years, has estimated the present value range of costs for all of the Houghton environmental matters, on a discounted basis, to be between approximately $ 5.5 million and $ 6.5 million as of September 30, 2021, for which $ 5.7 million was accrued within other accrued liabilities and other non-current liabilities on the Company’s Condensed Consolidated Balance Sheet as of September 30, 2021. Comparatively, as of December 31, 2020, the Company had $ 6.0 million accrued for with respect to these matters. The Company believes, although there can be no assurance regarding the outcome of other unrelated environmental matters, that it has made adequate accruals for costs associated with other environmental problems of which it is aware. Approximately $ 0.3 million and $ 0.1 million was accrued as of September 30, 2021 and December 31, 2020, respectively, to provide for such anticipated future environmental assessments and remediation costs. The Company previously disclosed in its 2020 Form 10-K that during the fourth quarter of 2020, one of the Company’s subsidiaries received a notice of inspection from a taxing authority in a country where certain of its subsidiaries operate which related to a non-income (indirect) tax that may be applicable to certain products the subsidiary sells. During the third quarter of 2021, the Company’s subsidiary received notice from the taxing authority that the inspection was closed, with no tax assessment issued. Based on this development, during the third quarter of 2021, the Company reversed its previously recorded $ 1.8 million liability related to this matter. The Company also reversed the associated $ 1.1 million indemnification receivable, as the asserted tax liability in part related to a Houghton entity acquired in the Combination and for the periods prior to the Combination, for which the Company would be indemnified by Houghton’s former owners. Based on all available information as of the date of this Report, the Company does not anticipate further tax inspection or liabilities related to this matter to be asserted by the taxing authority. During the first half of 2021, one of the Company’s Brazilian subsidiaries received a notice that it had prevailed on an existing legal claim in regard to certain non-income (indirect) taxes that had been previously charged and paid. The matter specifically relates to companies’ rights to exclude the state tax on goods circulation (a valued-added-tax or VAT equivalent, known in Brazil as “ICMS”) from the calculation of certain additional indirect taxes (specifically the program of social integration (“PIS”) and contribution for the financing of social security (“COFINS”)) levied by the Brazilian States on the sale of goods. In May 2021, the Brazilian Supreme Court concluded that ICMS should not be included in the tax base of PIS and COFINS, and confirmed the methodology for calculating the PIS and COFINS tax credit claims to which taxpayers are entitled. The Company’s Brazilian entities had previously filed legal or administrative disputes on this matter and are entitled to receive tax credits and interest dating back to five years preceding the date of their legal claims. As a result of these court rulings, during the second quarter of 2021, the Company recognized non-income tax credits of 67.0 million BRL or approximately $ 13.3 million, which included approximately $ 8.4 million for the PIS and COFINS tax credits as well as interest on these tax credits of $ 4.9 million. The tax credits to which the Company’s Brazilian subsidiaries are entitled are claimable once registered with the Brazilian tax authorities. The Company submitted its formal claim for tax credits in October 2021. These tax credits can be used to offset future Brazilian federal taxes and the Company currently anticipates using the full amount of credits during the five year period of time permitted. During the third quarter of 2021, the Brazilian Supreme Court ruled that interest income to which companies are entitled for matters such as this claim should not be taxable, which resulted in a reduction to the estimated income tax expense associated with the tax credits recorded. In connection with obtaining regulatory approvals for the Combination, certain steel and aluminum related product lines of Houghton were divested on August 1, 2019. In July 2021, the entity that acquired these divested product lines submitted an indemnification claim for certain alleged breaches of representation made by Houghton in the agreement pursuant to which such assets had been divested. The Company and the acquirer have agreed to extend the period for a possible negotiated resolution of this claim through November 30, 2021 so that both parties can evaluate the other’s positions with respect to the subject matters of the claim. The Company is evaluating the merits of the alleged losses in the indemnification claim received. As of the date of this Report, the Company does not believe it is reasonably possible to determine or quantify any possible exposure. During the third quarter of 2021, two of the Company’s locations suffered property damages as a result of flooding and fire. The Company maintains property insurance for all of its facilities globally. In Conshohocken, Pennsylvania, the Company’s global headquarters as well as its laboratory experienced property damages as a result of flooding from Hurricane Ida. Also, one of the Company’s North American production facilities in its Global Specialty Businesses segment experienced an electrical fire that resulted in damage and the temporary shutdown of production, and also required remediation, cleaning and subsequent restoration. The Company, its insurance adjuster and insurance carrier are actively managing the remediation and restoration activities associated with these events and at this time the Company has concluded, based on all available information and discussions with its insurance adjuster and insurance carrier, that the losses incurred during the third quarter of 2021 will be covered under the Company’s property insurance coverage, net of an aggregate deductible of $ 2.0 million. The Company has received advance payments from its insurers of $ 1.0 million and has recorded an insurance receivable associated with these events (and a gain on insurance recoveries for losses incurred) of $ 1.7 million as of September 30, 2021. The Company and its insurance carrier are in early stages of reviewing the impact of the electrical fire on the production facility’s operations as it relates to a potential business interruption insurance claim; however, as of the date of this Report, the Company cannot reasonably estimate any probable amount of business interruption insurance claim recoverable, therefore the Company has not recorded a gain contingency for a possible business interruption insurance claim as of September 30, 2021. The Company is party to other litigation which management currently believes will not have a material adverse effect on the Company’s results of operations, cash flows or financial condition. In addition, the Company has an immaterial amount of contractual purchase obligations.
