Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies [Text Block]	Note 18 – Commitments and Contingencies The Company previously disclosed in its 2021 Form 10-K that AC Products, Inc. (“ACP”), a wholly owned subsidiary, in 2007, agreed to operate two groundwater treatment systems, so as to hydraulically contain groundwater contamination emanating from ACP’s site until such time as the concentrations of contaminants are below the current Federal maximum contaminant level for four consecutive quarterly sampling events. In 2014, ACP ceased operation at one of its two groundwater treatment systems, as it had met the above condition for closure. As of June 30, 2022, ACP continues to operate the second groundwater treatment system, while the Company discusses with the relevant authorities whether the second groundwater treatment system meets the conditions for closure. In addition, the Santa Ana Regional Water Quality Control Board requested that ACP conduct additional indoor and outdoor soil vapor testing on and near the ACP site to confirm that ACP continues to meet the applicable local soil vapor standards. As of June 30, 2022, ACP performed such testing and is awaiting the review of the results from the Santa Ana Regional Water Quality Control Board. As of June 30, 2022, 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 2021 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 six months ended June 30, 2022, 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 $ 0.3 million (excluding costs of defense). The Company previously disclosed in its 2021 Form 10-K that it is party to certain environmental matters related to certain domestic and foreign properties. These environmental matters primarily require the Company to perform long-term monitoring and maintenance at each of the applicable sites. During the three and six months ended June 30, 2022, 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 approximately 30 years, has estimated the range of costs for all of these environmental matters, on a discounted basis, to be between approximately $ 5.0 million and $ 6.0 million as of June 30, 2022, for which $ 5.5 million was accrued within other accrued liabilities and other non-current liabilities on the Company’s Condensed Consolidated Balance Sheet as of June 30, 2022. Comparatively, as of December 31, 2021, the Company had $ 5.6 million accrued for with respect to these matters. Although there can be no assurance regarding the outcome of other unrelated environmental matters, the Company believes that it has made adequate accruals for costs associated with other environmental problems for which it is aware, and has accrued $ 0.4 million as of both June 30, 2022 and December 31, 2021, respectively, to provide for such anticipated future environmental assessments and remediation costs. The Company previously disclosed in its 2021 Form 10-K that during the first six months 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 related 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 five years preceding the date of their legal claims. As a result of these court rulings in the first six months of 2021, the Company recognized non-income tax credits of 67.0 million BRL or approximately $ 13.3 million, which includes 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 which the Company subsequently completed. 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. In connection with obtaining regulatory approvals for the Combination, certain steel and aluminum related product lines of Houghton were divested in August 2019. The Company previously disclosed in its 2021 Form 10-K that 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 responded to the subject matters of the indemnification claim and during the first quarter of 2022, the matter was resolved consistent with the Company’s expectations and position that there were no amounts owed by the Company. The Company previously disclosed in its 2021 Form 10-K that two of the Company’s locations suffered property damages as a result of flooding and fire, respectively. The Company maintains property insurance for all of its facilities globally. During the six months ended June 30, 2022, there have been no significant changes to the facts or circumstances of these previously disclosed matters, aside from the on-going restoration of both sites. 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 were covered under the Company’s property insurance coverage, net of an aggregate deductible of $ 2.0 million. The Company has received payments from its insurers of $ 2.1 million and has recorded an insurance receivable associated with these events (and a gain on insurance recoveries for losses incurred) of $ 0.9 million as of June 30, 2022. 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.
