Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Other Commitments As of December 31, 2023, we had contractual obligations to purchase products and services (primarily raw materials), capital projects, and energy totaling $79.2 million. These commitments extend beyond 2028. The Company has certain other letters of credit, guarantees and surety bonds outstanding at December 31, 2023, which are not material either individually or in the aggregate. In connection with the EP Divestiture, we undertook to indemnify and hold Evergreen Hill Enterprise harmless from claims and liabilities related to the EP business that were identified as excluded or specified liabilities in the related agreements up to an amount not to exceed $10 million. As of December 31, 2023, there were no material claims pending under this indemnification. Litigation Germany In January 2015, the Company initiated patent infringement proceedings in Germany against Glatz under multiple low ignition propensity ("LIP") related patents. In December 2017, the Dusseldorf Appeal Court affirmed the German District Court judgment on infringement of EP1482815 against Glatz. The Company filed an action against Glatz in the German District Court to set the amount of damages for the infringement and Glatz filed a counterclaim. Glatz filed an action in the German Patent Court to invalidate the German part of EP1482815. The German Patent Court held that some of the patent claims at issue were invalid and also that another claim at issue was valid. The Company appealed the portion of the decision with respect to the claims held to be invalid. The German Supreme Court held that the claims of German counterpart of EP1482815 relevant to the Glatz infringement action were invalid. This ruling has the effect of nullifying the infringement decision and injunction against Glatz and the Company’s claim for damages against Glatz. Glatz’s counterclaim against the Company was settled in June 2023. The Company recognized a $4.9 million loss during the three months ended June 30, 2023, which was included in Other income (expense), net in the Consolidated Statements of Income (Loss). The settlement was paid in the three months ended September 30, 2023. Environmental Matters The Company's operations are subject to various nations' federal, state and local laws, regulations and ordinances relating to environmental matters. The nature of the Company's operations exposes it to the risk of claims with respect to various environmental matters, and there can be no assurance that material costs or liabilities will not be incurred in connection with such claims. While the Company has incurred in the past several years, and will continue to incur, capital and operating expenditures in order to comply with environmental laws and regulations, it believes that its future cost of compliance with environmental laws, regulations and ordinances, and its exposure to liability for environmental claims and its obligation to participate in the remediation and monitoring of certain hazardous waste disposal sites, will not have a material effect on its financial condition or results of operations. However, future events, such as changes in existing laws and regulations, or unknown contamination or costs of remediation of sites owned, operated or used for waste disposal by the Company (including contamination caused by prior owners and operators of such sites or other waste generators) may give rise to additional costs which could have a material effect on its financial condition or results of operations. General Matters In the ordinary course of conducting business activities, the Company and its subsidiaries become involved in certain other judicial, administrative and regulatory proceedings involving both private parties and governmental authorities. These proceedings include insured and uninsured regulatory, employment, intellectual property, general and commercial liability, environmental and other matters. At this time, the Company does not expect any of these proceedings to have a material effect on its reputation, business, financial condition, results of operations or cash flows. However, the Company can give no assurance that the results of any such proceedings will not materially affect its reputation, business, financial condition, results of operations or cash flows.
