Commitments and Contingencies Disclosure [Abstract]
Contingent Liabilities	Contingent Liabilities Litigation and Claims Various legal actions, proceedings, and claims (generally, “matters”) are pending or may be instituted or asserted against the Company. The Company accrues for matters when losses are deemed probable and reasonably estimable. Any resulting adjustments, which could be material, are recorded in the period the adjustments are identified. As of December 31, 2016, the Company does not believe that there is a reasonable possibility that any material loss exceeding the amounts already accrued for matters, if any, has been incurred. However, the ultimate resolutions of these matters are inherently unpredictable and could require payment substantially in excess of the amounts that have been accrued or disclosed. On March 30, 2016, a putative class action complaint alleging conspiracy to fix the price of body sealing products used in automobiles and other light-duty vehicles was filed in Ontario against numerous automotive suppliers, including Cooper-Standard Holdings Inc., CSA U.S. and Cooper-Standard Automotive Canada Limited (“CS Defendants”) and Nishikawa Cooper LLC, a joint venture in which the Company holds a 40% interest. Plaintiffs purport to be indirect purchasers of body sealing products supplied by the CS Defendants and/or the other defendants during the relevant period. The plaintiffs seek recovery of damages on behalf of direct and indirect purchasers against all defendants in an amount to be determined, punitive damages, as well as pre-judgment and post-judgment interest and related costs and expenses of the litigation. The Company believes the claims asserted against the CS Defendants are without merit and intends to vigorously defend against these claims. Further, the Company does not believe that there is a material loss that is probable and reasonably estimable related to these claims. Environmental The Company is subject to a broad range of federal, state and local environmental and occupational safety and health laws and regulations in the United States and other countries, including those governing: emissions to air, discharges to water, noise and odor emissions; the generation, handling, storage, transportation, treatment, reclamation and disposal of chemicals and waste materials; the cleanup of contaminated properties; and human health and safety. The Company may incur substantial costs associated with hazardous substance contamination or exposure, including cleanup costs, fines, and civil or criminal sanctions, third party property or natural resource damage, personal injury claims or costs to upgrade or replace existing equipment as a result of violations of or liabilities under environmental laws or the failure to maintain or comply with environmental permits required at their locations. In addition, many of the Company’s current and former facilities are located on properties with long histories of industrial or commercial operations, and some of these properties have been subject to certain environmental investigations and remediation activities. The Company maintains environmental reserves for certain of these sites. As of December 31, 2016 and 2015, the Company had $5,490 and $6,384, respectively, reserved in accrued liabilities and other liabilities on the consolidated balance sheet on an undiscounted basis, which it believes are adequate. Because some environmental laws (such as the Comprehensive Environmental Response, Compensation and Liability Act and analogous state laws) can impose liability retroactively and regardless of fault on potentially responsible parties for the entire cost of cleanup at currently or formerly owned or operated facilities, as well as sites at which such parties disposed or arranged for disposal of hazardous waste, the Company could become liable for investigating or remediating contamination at their current or former properties or other properties (including offsite waste disposal locations). The Company may not always be in complete compliance with all applicable requirements of environmental laws or regulation, and the Company may receive notices of violation or become subject to enforcement actions or incur material costs or liabilities in connection with such requirements. In addition, new environmental requirements or changes to interpretations of existing requirements, or in their enforcement, could have a material adverse effect on the Company’s business, results of operations, and financial condition. The Company has made and will continue to make expenditures to comply with environmental requirements. While the Company’s costs to defend and settle known claims arising under environmental laws have not been material in the past and are not currently estimated to be material, such costs may be material in the future. Employment Contracts The Company has employment arrangements with certain key executives that provide for continuity of management. These arrangements include payments of multiples of annual salary, certain incentives, and continuation of benefits upon the occurrence of specified events in a manner that is believed to be consistent with comparable companies.
