Commitments And Contingencies Disclosure [Abstract]
Commitments And Contingencies Disclosure [Text Block]	Note 19 – Commitments and Contingencies The Company previously disclosed in its 2019 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, 2020, 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, 2020, 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 2019 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, 2020, 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 $ 0.5 million (excluding costs of defense). The Company previously disclosed in its 2019 Form 10-K that as a result of the closing of the Combination, the Company is now party to Houghton environmental matters related to certain domestic and foreign properties currently or previously owned. 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, 2020, 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 million and $ 6 million as of September 30, 2020, 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, 2020. Comparatively, as of December 31, 2019, the Company had $ 6.6 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 $ 0.1 million and $ 0.2 million were accrued as of September 30, 2020 and December 31, 2019, respectively, to provide for such anticipated future environmental assessments and remediation costs. 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.
