Commitments and Contingencies Disclosure [Text Block] | 11. COMMITMENTS AND CONTINGENCIES Legal Proceedings From time to time, the Company is subject to legal proceedings or claims that arise in the ordinary course of its business. The Company accrues for costs related to loss contingencies when such costs are probable and reasonably estimable. As of December 31, 2020 , the Company is not aware of any material pending legal proceedings or threatened litigation that would have a material adverse effect on the Company's results of operations, financial condition or cash flows, although no assurance can be given with respect to the ultimate outcome of pending actions. Refer to Note 18, “Legal Proceedings” of these consolidated financial statements for further discussion of legal proceedings. Environmental Compliance and Remediation Liabilities The Company's operations and products are subject to a variety of environmental laws and regulations in the jurisdictions in which the Company operates and sells products governing, among other things, air emissions, wastewater discharges, the use, handling and disposal of hazardous materials, soil and groundwater contamination, employee health and safety, and product content, performance and packaging. Also, certain environmental laws can impose the entire cost or a portion of the cost of investigating and cleaning up a contaminated site, regardless of fault, upon any one or more of a number of parties, including the current or previous owners or operators of the site. These environmental laws also impose liability on any person who arranges for the disposal or treatment of hazardous substances at a contaminated site. Third parties may also make claims against owners or operators of sites and users of disposal sites for personal injuries and property damage associated with releases of hazardous substances from those sites. Collateral In select instances, the Company has pledged specific inventory and machinery and equipment assets to serve as collateral on related payable or financing obligations. Warranty Liability The Company provides warranty terms that generally range from one to five years for various products and services relating to workmanship and materials supplied by the Company. In certain contracts, the Company has recourse provisions for items that would enable the Company to pursue recovery from third parties for amounts paid to customers under warranty provisions. Liquidated Damages In certain customer contracts, the Company has agreed to pay liquidated damages in the event of qualifying delivery or production delays. These damages are typically limited to a specific percentage of the value of the product in question and dependent on actual losses sustained by the customer. When the damages are determined to be probable and estimable, the damages are recorded as a reduction to revenue. During 2020 and 2019 , the Company incurred no liquidated damages and there was no reserve for liquidated damages as of December 31, 2020 . Workers' Compensation Reserves As of December 31, 2020 and 2019 , the Company had $74 and $115, respectively, accrued for self-insured workers' compensation liabilities. At the beginning of the third quarter of 2013, the Company began to self-insure for its workers' compensation liabilities, including reserves for self-retained losses. The Company entered into a guaranteed workers' compensation cost program at the beginning of the third quarter of 2016, but still maintains a liability for the trailing claims for the self-insured policy periods. Although the ultimate outcome of these matters may exceed the amounts recorded and additional losses may be incurred, the Company does not believe that any additional potential exposure for such liabilities will have a material adverse effect on the Company's consolidated financial position or results of operations. Health Insurance Reserves As of December 31, 2020 and 2019 , the Company had $550 and $344, respectively, accrued for health insurance liabilities. The Company self-insures for its health insurance liabilities, including establishing reserves for self-retained losses. Historical loss experience combined with actuarial evaluation methods and the application of risk transfer programs are used to determine required health insurance reserves. The Company takes into account claims incurred but not reported when determining its health insurance reserves. Health insurance reserves are included in accrued liabilities. While the Company's management believes that it has adequately reserved for these claims, the ultimate outcome of these matters may exceed the amounts recorded and additional losses may be incurred. Other As of December 31, 2020 , approximately 14% of the Company's employees were covered by two collective bargaining agreements with local unions at the Company's Cicero, Illinois and Neville Island, Pennsylvania locations. The current five -year collective bargaining agreement with the Neville Island union is expected to remain in effect through October 2022. A new collective bargaining agreement was negotiated and ratified with the Cicero Union and is effective from February 2018 and is expected to remain in effect through February 2022.
