Accounting Policies [Abstract]
Description of Business	Description of Business Cooper-Standard Holdings Inc. (together with its consolidated subsidiaries, the “Company” or “Cooper Standard”), through its wholly-owned subsidiary, Cooper-Standard Automotive Inc. (“CSA U.S.”), is a leading manufacturer of sealing, fuel and brake delivery, and fluid transfer systems. The Company’s products are primarily for use in passenger vehicles and light trucks that are manufactured by global automotive original equipment manufacturers (“OEMs”) and replacement markets. The Company conducts substantially all of its activities through its subsidiaries. Prior to its divestiture on April 1, 2019, the Company also operated an anti-vibration systems (“AVS”) product line. See Note 5. “Divestitures” for additional information. The Company believes it is the largest global producer of sealing systems, the second largest global producer of the types of fuel and brake delivery products that it manufactures and the third largest global producer of fluid transfer systems. The Company designs and manufactures its products in each major region of the world through a disciplined and sustained approach to engineering and operational excellence. The Company operates in 72 manufacturing locations and 49 design, engineering, administrative and logistics locations in 21 countries around the world. Subsequent Event In January 2021, one of the Company’s top customers announced restructuring activities in South America, including its intention to cease manufacturing operations in Brazil. As a result, Cooper Standard’s Brazil manufacturing operations and sales attributable to that customer will be significantly impacted. The Company is assessing the impact of this announcement on its 2021 financial results, but does not expect the action to have a material impact on its business, results of operations, financial condition or cash flows.

Significant Accounting Policies

Significant Accounting Policies	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). Certain balances in prior periods have been conformed to the current presentation. Summary of Significant Accounting Policies Principles of Consolidation – The consolidated financial statements include the accounts of the Company and the wholly-owned and less than wholly-owned subsidiaries controlled by the Company. All material intercompany accounts and transactions have been eliminated. Acquired businesses are included in the consolidated financial statements from the dates of acquisition or when the Company gained control. The equity method of accounting is followed for investments in which the Company does not have control, but does have the ability to exercise significant influence over operating and financial policies. Generally, this occurs when ownership is between 20% to 50%. Foreign Currency – The financial statements of foreign subsidiaries are translated to U.S. dollars at the end-of-period exchange rates for assets and liabilities and at a weighted average exchange rate for each period for revenues and expenses. Translation adjustments for those subsidiaries whose local currency is their functional currency are recorded as a component of accumulated other comprehensive income (loss) in stockholders’ equity (“AOCI”). Transaction related gains and losses arising from fluctuations in currency exchange rates on transactions denominated in currencies other than the functional currency are recognized in earnings as incurred, except for those intercompany balances which are designated as long-term. Cash and Cash Equivalents – The Company considers highly liquid investments with an original maturity of three months or less to be cash equivalents. Accounts Receivable – The Company records trade accounts receivable when revenue is recorded in accordance with its revenue recognition policy and relieves accounts receivable when payments are received from customers. Accounts receivable are written off when it is apparent such amounts are not collectible. Generally, the Company does not require collateral for its accounts receivable, nor is interest charged on accounts receivable balances. The Company receives bank notes from its customers, which are classified as other current assets in the consolidated balance sheets, for certain amounts of accounts receivable, primarily in China. The Company may elect to hold such bank notes until maturity, exchange them with suppliers to settle liabilities, or sell them to third party financial institutions in exchange for cash. Allowance for Credit Losses – An allowance for credit losses is established through charges to the provision for credit losses when it is probable that the outstanding receivable or reimbursable tooling will not be collected. The Company evaluates the adequacy of the allowance for credit losses on a periodic basis, including historical trends in collections and write-offs, management’s judgment of the probability of collecting accounts and management’s evaluation of business risk. This evaluation is inherently subjective, as it requires estimates that are susceptible to revision as more information becomes available. The allowance for credit losses was $7,100 and $9,149 as of December 31, 2020 and 2019, respectively. Advertising Expense – Expenses incurred for advertising are generally expensed when incurred. Advertising expense was $425, $711 and $1,493 for the years ended December 31, 2020, 2019 and 2018, respectively. Inventories – Inventories are valued at lower of cost or net realizable value. Cost is determined using the first-in, first-out method. Finished goods and work-in-process inventories include material, labor and manufacturing overhead costs. The Company records inventory reserves for inventory in excess of production and/or forecasted requirements and for obsolete inventory. December 31, 2020 2019 Finished goods $ 39,136 $ 57,070 Work in process 35,477 33,753 Raw materials and supplies 69,129 52,616 $ 143,742 $ 143,439 Derivative Financial Instruments – Derivative financial instruments are utilized by the Company to reduce foreign currency exchange. The Company has established policies and procedures for risk assessment and the approval, reporting and monitoring of derivative financial instrument activities. On the date the derivative is established, the Company designates the derivative as either a fair value hedge, a cash flow hedge or a net investment hedge in accordance with its established policy. The Company does not enter into derivative financial instruments for trading or speculative purposes. Income Taxes – Deferred tax assets or liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using enacted tax laws and rates. A valuation allowance is provided on deferred tax assets if the Company determines that it is more likely than not that the asset will not be realized. Long-lived Assets – Property, plant and equipment are recorded at cost and depreciated using primarily the straight-line method over estimated useful lives. Leasehold improvements are amortized over the expected life of the asset or term of the lease, whichever is shorter. Intangibles with finite lives, which include technology and customer relationships, are amortized over estimated useful lives. The Company evaluates the recoverability of long-lived assets when events and circumstances indicate that the assets may be impaired and the undiscounted net cash flows estimated to be generated by those assets are less than their carrying value. If the net carrying value exceeds the fair value, an impairment loss exists and is calculated based on either estimated salvage value or estimated orderly liquidation value. Pre-production Costs Related to Long Term Supply Arrangements – Costs for molds, dies and other tools owned by the Company to produce products under long-term supply arrangements are recorded at cost in property, plant and equipment and amortized over the lesser of three Goodwill – The Company tests goodwill for impairment on an annual basis in the fourth quarter, or more frequently if an event occurs or circumstances indicate the carrying amount may be impaired. Goodwill impairment testing is performed at the reporting unit level. The impairment test involves first qualitatively assessing goodwill for impairment. If the qualitative assessment is not met, a quantitative assessment is performed by comparing the estimated fair value of each reporting unit to its carrying value. If the carrying value exceeds the fair value, an impairment charge is recorded based on that difference. The Company’s organizational structure changed on January 1, 2020. See Note 24. “Business Segments” for further detail on this reorganization of our business. The change in organizational structure of the business represented a triggering event to test goodwill for impairment as of January 1, 2020. No impairment was identified as a result of completing the goodwill impairment test. Other than the change in organizational structure event noted above, there were no other indicators of potential impairment during the year ended December 31, 2020. In the fourth quarter of 2020, the Company completed a quantitative goodwill impairment assessment, and after evaluating the results, events and circumstances, the Company concluded that sufficient evidence existed to assert quantitatively that the estimated fair value of the reporting units remained in excess of their carrying values. In the fourth quarter of 2019, the Company completed a quantitative goodwill impairment assessment for its North America reporting unit, and no impairment was identified as a result of completing the goodwill impairment test. Business Combinations – The purchase price of an acquired business is allocated to its identifiable assets and liabilities based on estimated fair values. The excess of the purchase price over the amount allocated to the assets and liabilities, if any, is recorded as goodwill. Determining the fair values of assets acquired and liabilities assumed requires management’s judgment, the utilization of independent appraisal firms and often involves the use of significant estimates and assumptions with respect to the timing and amount of future cash flows, market rate assumptions, actuarial assumptions, and appropriate discount rates, among other items. Revenue Recognition and Sales Commitments – In accordance with ASC 606, Revenue from Contracts with Customers , revenue is recognized when the performance obligations are satisfied. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC 606. The Company has one major performance obligation category: manufactured parts. A contract’s transaction price is allocated to each distinct performance obligation and recognized when the performance obligation is satisfied. The Company’s contracts may include multiple performance obligations. For such contracts, the Company generally allocates the contract’s transaction price to each performance obligation based on the purchase order or other arranged pricing. Revenue is recognized for manufactured parts at a point in time, generally when products are shipped or delivered. The point at which revenue is recognized often depends on the shipping terms. The Company usually enters into agreements with customers to produce products at the beginning of a vehicle’s life. Blanket purchase orders received from customers and related documents generally establish the annual terms, including pricing, related to a vehicle model. Although purchase orders do not usually specify quantities, fulfillment of customers’ purchasing requirements can be the Company’s obligation for the entire production life of the vehicle. These agreements generally may be terminated by the Company’s customer at any time, but such cancellations have historically been minimal. Customers typically pay for parts based on customary business practices with payment terms generally between 30 and 90 days. The Company has no significant financing arrangements with customers. The Company applies the optional exemption to forgo disclosing information about its remaining performance obligations because its contracts usually have an original expected duration of one year or less. It also applies an accounting policy to treat shipping and handling costs that are incurred after revenue is recognizable as a fulfillment activity by expensing such costs as incurred, instead of as a separate performance obligation. This is consistent with the Company’s historical accounting practices. The Company has chosen to present revenue net of sales and other similar taxes, which is also consistent with its historical accounting practices. Shipping and Handling – Amounts billed to customers related to shipping and handling are included in sales in the Company’s consolidated statements of operations. Shipping and handling costs are included in cost of products sold in the Company’s consolidated statements of operations. Research and Development – Engineering, research and development, and program management costs are charged to selling, administration and engineering expenses as incurred and totaled $101,607, $114,854 and $122,529 for the years ended December 31, 2020, 2019 and 2018, respectively. Share-based Compensation – The Company measures share-based compensation expense at fair value and generally recognizes such expenses on a straight-line basis over the vesting period of the share-based employee awards. See Note 21. “Share-Based Compensation” for additional information.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	New Accounting Pronouncements Recently Adopted Accounting Pronouncements The Company adopted the following Accounting Standards Updates (“ASU”) in 2020: ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) On January 1, 2020, the Company adopted Accounting Standards Codification (“ASC”) 326, Financial Instruments – Credit Losses, and all related amendments using the modified retrospective method whereby the cumulative effect of adopting the standard was recognized in equity at the date of initial application. Comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The most prominent among the changes in the standard is the consideration of losses not yet incurred, but expected, based on current conditions and future forecasts. Adoption of the new standard resulted in an immaterial increase in the allowance for credit losses, which decreased the tooling receivable on the Company’s condensed consolidated balance sheet in 2020. The increase in credit loss expense was recorded as an adjustment to the opening balance of retained earnings. Adoption of the new standard had no impact on the Company’s condensed consolidated statement of operations or on cash provided by (used in) operating, financing or investing activities on its condensed consolidated cash flow statements. The cumulative effects of the changes made to the Company’s condensed consolidated balance sheet as of January 1, 2020 were as follows: Balance as of December 31, 2019 Adjustments due to adoption of ASC 326 Balance as of January 1, 2020 Tooling receivable, net $ 148,175 $ (1,573) $ 146,602 Retained earnings 619,448 (1,573) 617,875 The Company adopted the recently issued accounting pronouncement summarized as follows, which had an immaterial impact on its consolidated financial statements and disclosures: Standard Description Impact Effective Date ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans Modifies the disclosure requirements for ASC Topic 715 by removing and modifying existing disclosure requirements while also adding new disclosures. Adoption of this standard resulted in additional pension disclosures while also removing certain other disclosures. Specifically, the weighted-average interest crediting rate for the U.S. cash balance plan was added while accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year and the effects of a one-percentage-point change in the assumed health care cost trend rate were removed. December 31, 2020 The Company adopted the following ASUs in 2020, which did not have a material impact on its consolidated financial statements: Standard Description Effective Date ASU 2018-15 , Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract Aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. January 1, 2020 ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting Provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. January 1, 2020 Recently Issued Accounting Pronouncements The Company considered the recently issued accounting pronouncements summarized as follows, which will not have a material impact on its consolidated financial statements or disclosures: Standard Description Effective Date ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes Modifies ASC Topic 740 by removing certain exceptions and amending existing guidance in order to simplify the accounting for income taxes. January 1, 2021 ASU 2021-01, Reference Rate Reform (Topic 848): Scope Clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition and tailors the existing guidance to derivative instruments affected by the discounting transition.

Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Divestitures 2020 Divestiture In the fourth quarter of 2019, management approved a plan to sell its European rubber fluid transfer and specialty sealing businesses, as well as its Indian operations. The entities and the associated assets and liabilities met the criteria for presentation as held for sale as of March 31, 2020, and depreciation of long-lived assets ceased. The divestiture did not meet the criteria for presentation as a discontinued operation. Upon meeting the criteria for held for sale classification, the Company recorded non-cash impairment charges of $86,470 during the six months ended June 30, 2020 to reduce the carrying value of the held for sale entities to fair value less costs to sell. Fair value, which is categorized within Level 3 of the fair value hierarchy, was determined using a market approach, estimated based on expected proceeds. The fair value less costs to sell were assessed each reporting period that the asset group remained classified as held for sale. The difference between the impairment of the carrying value on the divested assets compared to the impairment recorded in the consolidated statements of operations is due to foreign currency translation offset by costs to sell incurred in the second quarter. The impairment charge includes the non-cash cumulative foreign currency translation losses recorded in equity related to the divested entities. On July 1, 2020, the Company completed the divestiture of its European rubber fluid transfer and specialty sealing businesses, as well as its Indian operations, to Mutares SE & Co. KGaA (“Mutares”). The transaction included payment denominated in Euro of €9,000, which consisted of €6,500 in cash paid and €2,500 in deferred payment obligations, payable in December 2021. Upon finalizing the sale in the third quarter of 2020 and including subsequent adjustments in the fourth quarter of 2020, the Company recorded a net gain on deconsolidation of the businesses of $353 during the year ended December 31, 2020. In addition, at closing, the Company and Mutares entered into certain ancillary agreements providing for the transition of the European rubber fluid transfer and specialty sealing businesses and Indian operations. The major classes of assets and liabilities divested were as follows: July 1, 2020 Cash and cash equivalents $ 11,162 Accounts receivable, net 18,825 Tooling receivable, net 4,770 Inventories 17,022 Prepaid expenses 2,728 Other current assets 8,873 Property, plant and equipment, net 39,913 Operating lease right-of-use assets, net 2,946 Intangible assets, net 4,992 Other assets 4,114 Impairment of carrying value (85,622) Total assets divested $ 29,723 Accounts payable $ 13,219 Payroll liabilities 7,135 Accrued liabilities 5,744 Current operating lease liabilities 918 Pension benefits 3,574 Postretirement benefits other than pensions 2,778 Long-term operating lease liabilities 2,286 Other liabilities 1,934 Total liabilities divested $ 37,588 2020 Joint Venture Deconsolidation In the third quarter of 2020, management approved and completed a plan to sell the Company’s entire controlling equity interest of a joint venture in the Asia Pacific region.

On April 1, 2019, the Company completed its sale of the AVS product line to Continental AG. The total sale price of the transaction was $265,000, subject to certain adjustments. Cash proceeds received in the second quarter of 2019 were $243,362 after adjusting for certain liabilities assumed by the purchaser. The Company recognized a gain on the divestiture of $191,571 during the year ended December 31, 2019.

Contract Estimates The amount of revenue recognized is usually based on the purchase order price and adjusted for variable consideration, including pricing concessions. The Company accrues for pricing concessions by reducing revenue as products are shipped or delivered. The accruals are based on historical experience, anticipated performance and management’s best judgment. The Company also generally has ongoing adjustments to customer pricing arrangements based on the content and cost of its products. Such pricing accruals are adjusted as they are settled with customers. Customer returns are usually related to quality or shipment issues and are recorded as a reduction of revenue. The Company generally does not recognize significant return obligations due to their infrequent nature. Contract Balances The Company’s contract assets consist of unbilled amounts associated with variable pricing arrangements in its Asia Pacific region. Once pricing is finalized, contract assets are transferred to accounts receivable. As a result, the timing of revenue recognition and billings, as well as changes in foreign exchange rates, will impact contract assets on an ongoing basis. Changes during the year ended December 31, 2020 were not materially impacted by any other factors. The Company’s contract liabilities consist of advance payments received and due from customers. Net contract assets (liabilities) consisted of the following: December 31, 2020 December 31, 2019 Change Contract assets $ 777 $ 1,100 $ (323) Contract liabilities (27) (61) 34 Net contract assets $ 750 $ 1,039 $ (289) Other The Company at times enters into agreements that provide for lump sum payments to customers. These payment agreements are recorded as a reduction of revenue during the period the commitment is made. Amounts related to commitments of future payments to customers on the condensed consolidated balance sheets as of December 31, 2020 and December 31, 2019 were current liabilities of $16,932 and $12,916, respectively, and long-term liabilities of $6,828 and $9,502, respectively. The Company provides assurance-type warranties to its customers. Such warranties provide customers with assurance that the related product will function as intended and complies with any agreed-upon specifications and are recognized in costs of products sold.

Leases [Abstract]
Leases of Lessee Disclosure [Text Block]	Leases The Company primarily has operating and finance leases for certain manufacturing facilities, corporate offices and certain equipment. Operating leases are included in operating lease right-of-use assets, current operating lease liabilities and long-term operating lease liabilities on the Company’s consolidated balance sheets. Finance leases are included in property, plant and equipment, net, debt payable within one year, and long-term debt on the Company’s consolidated balance sheets. Lease right-of-use assets are recognized at commencement date based upon the present value of the remaining future minimum lease payments over the lease term. The Company’s lease terms include options to renew or terminate the lease when it is reasonably certain that it will exercise the option. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based upon information available at the commencement date to determine the present value of future lease payments. The Company has lease agreements with lease and non-lease components. For real estate leases, these components are accounted for separately, while for equipment leases, the Company accounts for the lease and non-lease components as a single lease component. Variable lease expense includes payments based upon changes in a rate or index, such as consumer price indexes, as well as usage of the leased asset. Short-term lease expense includes leases with terms, at lease commencement, of 12 months or less and no purchase option reasonably certain to be exercised. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. The components of lease expense were as follows: Year Ended December 31, 2020 Year Ended December 31, 2019 Operating lease expense $ 32,053 $ 33,360 Short-term lease expense 5,069 3,557 Variable lease expense 942 1,619 Finance lease expense: Amortization of right-of-use assets 2,564 2,550 Interest on lease liabilities 1,551 1,438 Total lease expense $ 42,179 $ 42,524 The Company recorded impairment charges of $647 due to the deterioration of financial results at a certain location in North America during the year ended December 31, 2020.

A summary of these asset impairment charges is as follows: Year Ended December 31, 2020 2019 2018 North America $ 947 $ — $ — Europe 11,938 9,943 30,978 Asia Pacific 4,080 13,146 11,937 South America — — — Total Automotive 16,965 23,089 42,915 Corporate and other 281 50 — Total $ 17,246 $ 23,139 $ 42,915 The Company continues to monitor the significant global economic uncertainty as a result of COVID-19 to assess the outlook for demand for products and the impact on the Company’s business and overall financial performance. A lack of recovery or further deterioration in market conditions and production volumes, among other factors, as a result of the COVID-19 pandemic could result in an impairment charge in future periods.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangibles	Goodwill and Intangible Assets Goodwill Changes in the carrying amount of goodwill by reporting unit for the years ended December 31, 2020 and 2019 were as follows: North America Industrial Specialty Group Total Balance as of December 31, 2018 $ 143,681 $ — $ 143,681 Adjustments related to recent acquisitions (1,689) — (1,689) Foreign exchange translation 195 — 195 Balance as of December 31, 2019 $ 142,187 $ — $ 142,187 Change in organizational structure (14,036) 14,036 — Foreign exchange translation 63 — 63 Balance as of December 31, 2020 $ 128,214 $ 14,036 $ 142,250 The Company’s organizational structure changed on January 1, 2020. See Note 24. “Business Segments” for further detail on this reorganization of the Company’s business. Prior to this change in organizational structure, the Company’s North America operating segment was the only reporting unit in which goodwill was recorded. As a result of the change in organizational structure, a portion of the goodwill that was previously attributable to the North America reporting unit was reallocated to the Industrial Specialty Group reporting unit based on the relative fair value approach. The Industrial Specialty Group reporting unit is a component of the Advanced Technology Group operating segment, which is reflected in “Corporate, eliminations and other”. The change in organizational structure of the business represented a triggering event to test goodwill for impairment as of January 1, 2020. No impairment was identified as a result of completing the goodwill impairment test. The Company performed its annual impairment analysis of goodwill during the fourth quarter of 2020. The fair value of each reporting unit is determined and compared to the carrying value. If the carrying value exceeds the fair value, an impairment charge is recorded based on that difference. The Company's annual goodwill impairment analysis resulted in no impairment for 2020. The Company continues to monitor the significant global economic uncertainty as a result of COVID-19 to assess the outlook for demand for products and the impact on the Company’s business and overall financial performance. A lack of recovery or further deterioration in market conditions and production volumes, among other factors, as a result of the COVID-19 pandemic could result in an impairment charge in future periods. The Company's annual goodwill impairment analysis resulted in no impairment for 2019. During the fourth quarter of 2018, the Company noted potential adverse changes in operating conditions. The Company tested goodwill for impairment and recorded a goodwill impairment charge of $45,281 after determining the carrying value of the Europe and Asia Pacific reporting units exceeded their fair value. Intangible Assets Definite-lived intangible assets and accumulated amortization balances as of December 31, 2020 and 2019 were as follows: Gross Carrying Amount Accumulated Amortization Net Carrying Amount Customer relationships $ 155,409 $ (122,657) $ 32,752 Other 44,826 (9,899) 34,927 Balance as of December 31, 2020 $ 200,235 $ (132,556) $ 67,679 Customer relationships $ 156,557 $ (113,871) $ 42,686 Other 49,556 (7,873) 41,683 Balance as of December 31, 2019 $ 206,113 $ (121,744) $ 84,369 During the fourth quarter of 2018, the Company recorded an impairment loss of $791 for customer relationships in its Europe operating segment. Estimated amortization expense for the next five years is shown in the table below: Year Expense 2021 $ 7,320 2022 7,320 2023 7,307 2024 7,048 2025 6,593

The net proceeds from the Senior Notes were used to repay the non-extended term loan outstanding under the Term Loan Facility, defined below, and to pay fees and expenses related to the refinancing. The Senior Notes are guaranteed by the Company, CS Intermediate HoldCo 1 LLC, as well as each of the Issuer’s wholly-owned existing or subsequently organized U.S. subsidiaries, subject to certain exceptions, to the extent such subsidiary guarantees the senior asset-based revolving credit facility (“ABL Facility”) and the senior term loan facility (“Term Loan Facility”). The Issuer may redeem all or part of the Senior Notes at various points in time prior to maturity, as described in the Indenture. The Senior Notes mature on November 15, 2026. Interest on the Senior Notes is payable semi-annually in arrears in cash on May 15 and November 15 of each year. Upon the occurrence of certain events constituting a Change of Control (as defined in the Indenture), the Issuer will be required to make an offer to repurchase all of the Senior Notes at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any. The Indenture contains certain covenants that limit the Issuer’s and its subsidiaries’ ability to, among other things, make restricted payments; sell assets; create or incur liens; enter into sale and lease-back transactions; and merge or consolidate with other entities. These covenants are subject to a number of important limitations and exceptions. The Indenture also provides for events of default, which, if any occur, would permit or require the principal, premium, if any, interest and any other monetary obligations on all the then-outstanding Senior Notes to be due and payable immediately. The Company paid approximately $7,055 of debt issuance costs in connection with the transaction. The debt issuance costs are being amortized into interest expense over the term of the Senior Notes.

Interest on the Senior Secured Notes is payable semi-annually in arrears in cash on June 1 and December 1 of each year, commencing on December 1, 2020. The Indenture contains certain covenants that limit the Issuer’s and its subsidiaries’ ability to, among other things, incur or guarantee additional indebtedness or issue certain preferred stock; make restricted payments; sell assets; create or incur liens; and merge or consolidate with other entities. These covenants are subject to a number of important limitations and exceptions.

In March 2020, the Company entered into the First Amendment of the Third Amended and Restated Loan Agreement (“the Amendment”). As a result of the Amendment, the senior asset-based revolving credit facility (“ABL Facility”) maturity was extended to March 2025 and the aggregate revolving loan commitment was reduced to $180,000. The aggregate revolving loan availability includes a $100,000 letter of credit sub-facility and a $25,000 swing line sub-facility. The ABL Facility also provides for an uncommitted $100,000 incremental loan facility, for a potential total ABL Facility of $280,000 (if requested by the Borrowers and the lenders agree to fund such increase). No consent of any lender (other than those participating in the increase) is required to effect any such increase. As of December 31, 2020, there were no obligations outstanding under the ABL Facility. The Company’s borrowing base was $173,745. Net the greater of 10% of the borrowing base or $15,000 that cannot be borrowed without triggering the fixed charge coverage ratio maintenance covenant and $5,517 of outstanding letters of credit, the Company effectively had $150,854 available for borrowing under its ABL facility. Maturity . Any borrowings under our ABL Facility will mature, and the commitments of the lenders under our ABL Facility will terminate, on March 24, 2025. Borrowing Base . Loan and letter of credit availability under the ABL Facility is subject to a borrowing base, which at any time is limited to the lesser of: (A) the maximum facility amount (subject to certain adjustments) and (B) (i) up to 85% of eligible accounts receivable; plus (ii) the lesser of 70% of eligible inventory or 85% of the appraised net orderly liquidation value of eligible inventory; plus (iii) up to the lesser of $30.0 million and 85% of eligible tooling accounts receivable; minus reserves established by the Agent. The accounts receivable portion of the borrowing base is subject to certain formulaic limitations (including concentration limits). The inventory portion of the borrowing base is limited to eligible inventory, as determined by the Agent. The borrowing base is also subject to certain reserves, which are established by the Agent (which may include changes to the advance rates indicated above). Loan availability under the ABL Facility is apportioned as follows: $180,000 to the U.S. Borrower, which includes a $40,000 sublimit to the Dutch Borrower and $20,000 to the Canadian Borrower. Guarantees; Security .

Interest . Borrowings under the ABL Facility bear interest at a rate equal to, at the Borrowers’ option: • in the case of borrowings by the U.S. Borrower, LIBOR or the base rate plus, in each case, an applicable margin; or • in the case of borrowings by the Canadian Borrower, bankers’ acceptance (“BA”) rate, Canadian prime rate or Canadian base rate plus, in each case, an applicable margin; or • in the case of borrowings by the Dutch Borrower, LIBOR plus an applicable margin. The initial applicable margin was 1.50% with respect to the LIBOR or Canadian BA rate-based borrowings and 0.50% with respect to U.S. base rate, Canadian prime rate and Canadian base rate borrowings, until April 1, 2020.

The ABL Facility also contains various events of default that are customary for comparable facilities. Debt Issuance Costs . As of December 31, 2020 and 2019, the Company had $1,029 and $657, respectively, of unamortized debt issuance costs related to the ABL Facility. Term Loan Facility On November 2, 2016, CSA U.S., as borrower, entered into Amendment No. 1 to the Term Loan Facility, which provides for loans in an aggregate principal amount of $340,000. Subject to certain conditions, the Term Loan Facility, without the consent of the then-existing lenders (but subject to the receipt of commitments), may be expanded (or a new term loan or revolving facility added) by an amount that will not cause the consolidated secured net debt ratio to exceed 2.25 to 1.00 plus $400,000 plus any voluntary prepayments (including revolving facility and ABL Facility to the extent commitments are reduced) not funded from proceeds of long-term indebtedness. On May 2, 2017, the Company entered into Amendment No. 2 to the Term Loan Facility to modify the interest rate. Subsequently, on March 6, 2018, the Company entered into Amendment No. 3 to the Term Loan Facility to further modify the interest rate. In accordance with this amendment, borrowings under the Term Loan Facility bear interest, at the Company’s option, at either (1) with respect to Eurodollar rate loans, the greater of the applicable Eurodollar rate and 0.75% plus 2.00% per annum, or (2) with respect to base rate loans, the base rate, (which is the highest of the then current federal funds rate plus 0.50%, the prime rate most recently announced by the administrative agent under the term loan, and the one-month Eurodollar rate plus 1.0%) plus 1.0% per annum. As a result of Amendment No. 3, the Company recognized a loss on refinancing and extinguishment of debt of $770 in the twelve months ended December 31, 2018, which was due to the partial write off of new and unamortized debt issuance costs and unamortized original issue discount Maturity . The Term Loan Facility matures on November 2, 2023, unless earlier terminated. Guarantees .

Fair Value of Financial Instrum

Fair Value of Financial Instruments	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value Measurements and Financial Instruments Fair Value Measurements Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based upon assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three-tier fair value hierarchy is utilized, which prioritizes the inputs used in measuring fair value as follows: Level 1: Observable inputs such as quoted prices in active markets; Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Items Measured at Fair Value on a Recurring Basis Estimates of the fair value of foreign currency and interest rate derivative instruments are determined using exchange traded prices and rates. The Company also considers the risk of non-performance in the estimation of fair value and includes an adjustment for non-performance risk in the measure of fair value of derivative instruments. In certain instances where market data is not available, the Company uses management judgment to develop assumptions that are used to determine fair value. Fair value measurements and the fair value hierarchy level for the Company’s liabilities measured or disclosed at fair value on a recurring basis as of December 31, 2020 and 2019, was as follows: December 31, 2020 December 31, 2019 Input Forward foreign exchange contracts - other current assets $ 1,826 $ 467 Level 2 Forward foreign exchange contracts - accrued liabilities $ (750) $ (42) Level 2 Items Measured at Fair Value on a Nonrecurring Basis In addition to items that are measured at fair value on a recurring basis, the Company measures certain assets and liabilities at fair value on a nonrecurring basis, which are not included in the table above. As these nonrecurring fair value measurements are generally determined using unobservable inputs, these fair value measurements are classified within Level 3 of the fair value hierarchy. For further information on assets and liabilities measured at fair value on a nonrecurring basis see Note 2. “Basis of Presentation and Summary of Significant Accounting Policies,” Note 4. “Acquisitions”, Note 5. “Divestitures” and Note 9. “Property, Plant and Equipment.” Items Not Carried at Fair Value Fair values of the Company’s Senior Notes, Senior Secured Notes, and Term Loan Facility were as follows: December 31, 2020 December 31, 2019 Aggregate fair value $ 965,052 $ 693,600 Aggregate carrying value (1) $ 976,400 $ 729,800 (1) Excludes unamortized debt issuance costs and unamortized original issue discount. Fair values were based on quoted market prices and are classified within Level 1 of the fair value hierarchy. Derivative Instruments and Hedging Activities The Company i s exposed to fluctuations in foreign currency exchange rates, interest rates and commodity prices. The Company enters into derivative instruments primarily to hedge portions of its forecasted foreign currency denominated cash flows and designates these derivative instruments as cash flow hedges in order to qualify for hedge accounting. The Company formally documents its hedge relationships, including the identification of the hedging instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the cash flow hedges. The Company also formally assesses whether a cash flow hedge is highly effective in offsetting changes in the cash flows of the hedged item. Derivatives are recorded at fair value in other current assets, other assets, accrued liabilities and other long-term liabilities. For a cash flow hedge, the effective portion of the change in fair value of the derivative is recorded in accumulated other comprehensive income (loss) (“AOCI”) in the consolidated balance sheet and reclassified into earnings when the underlying hedged transaction is realized. The realized gains and losses are recorded on the same line as the hedged transaction in the consolidated statements of operations. The Company is exposed to credit risk in the event of nonperformance by its counterparties on its derivative financial instruments. The Company mitigates this credit risk exposure by entering into agreements directly with major financial institutions with high credit standards that are expected to fully satisfy their obligations under the contracts. Cash Flow Hedges Forward Foreign Exchange Contracts – The Company uses forward contracts to mitigate the potential volatility to earnings and cash flow arising from changes in currency exchange rates that impact the Company’s foreign currency transactions. The principal currencies hedged by the Company include various European currencies, the Canadian Dollar, the Mexican Peso, and the Brazilian Real. As of December 31, 2020 and 2019, the notional amount of these contracts was $97,503 and $92,150, respectively, and consisted of hedges of transactions up to December 2021. Pretax amounts related to the Company’s cash flow hedges that were recognized in other comprehensive income (loss) (“OCI”) were as follows: Gain (Loss) Recognized in OCI Year Ended December 31, 2020 2019 Forward foreign exchange contracts $ (6,280) $ 3,812 Pretax amounts related to the Company’s cash flow hedges that were reclassified from AOCI were as follows: Gain (Loss) Reclassified from AOCI to Income Year Ended December 31, Classification 2020 2019 Forward foreign exchange contracts Cost of products sold $ (6,945) $ 2,773

Receivables [Abstract]
Accounts Receivable Factoring	Accounts Receivable Factoring As a part of its working capital management, the Company sells certain receivables through a third-party financial institution in a pan-European program (the “Factor”). The amount sold varies each month based on the amount of underlying receivables and cash flow needs of the Company. These are permitted transactions under the Company’s credit agreements governing the ABL Facility and Term Loan Facility and the indentures governing the Senior Notes and Senior Secured Notes. The European factoring facility, which was renewed in March 2020, allows the Company to factor up to €120 million of its Euro-denominated accounts receivable, accelerating access to cash and reducing credit risk. The factoring facility expires in December 2023. Costs incurred on the sale of receivables are recorded in other expense, net in the consolidated statements of operations. Liabilities related to the factoring program are recorded in accrued liabilities in the consolidated balance sheet. The sale of receivables under this contract is considered an off-balance sheet arrangement to the Company and is accounted for as a true sale and excluded from accounts receivable in the consolidated balance sheet. Amounts outstanding under receivable transfer agreements entered into by various locations as of the period end were as follows: December 31, 2020 December 31, 2019 Off-balance sheet arrangements $ 85,108 $ 103,818 Accounts receivable factored and related costs throughout the period were as follows: Off-Balance Sheet Arrangements Year Ended December 31, 2020 2019 Accounts receivable factored $ 476,405 $ 556,102 Off-Balance Sheet Arrangements Year Ended December 31, 2020 2019 2018 Costs $ 776 $ 1,007 $ 1,248

Retirement Benefits [Abstract]
Pensions	Pension The Company maintains defined benefit pension plans covering employees located in the United States as well as certain international locations. The majority of these plans are frozen, and all are closed to new employees. Benefits generally are based on compensation, length of service and age for salaried employees and on length of service for hourly employees. The Company’s policy is to fund pension plans such that sufficient assets will be available to meet future benefit requirements and contribute amounts deductible for United States federal income tax purposes or amounts required by local statute. The Company also sponsors voluntary defined contribution plans for certain salaried and hourly U.S. employees of the Company. The Company matches contributions of participants, up to various limits in all plans. The Company also sponsors retirement plans that include Company non-elective contributions. Non-elective and matching contributions under these plans totaled $13,537, $14,514 and $16,076 for the years ended December 31, 2020, 2019 and 2018, respectively.

Under the corridor approach, net unrecognized actuarial losses in excess of 10% of the greater of i) the projected benefit obligation or ii) the fair value of plan assets are amortized over future periods. The accumulated benefit obligation for all domestic and international defined benefit pension plans was $271,397 and $186,652 as of December 31, 2020 and $255,935 and $174,273 as of December 31, 2019, respectively. As of December 31, 2020, the fair value of plan assets for three of the Company’s defined benefit plans exceeded the projected benefit obligations of $286,102 by $12,434. The components of net periodic benefit (income) cost for the Company’s defined benefit plans were as follows: Year Ended December 31, 2020 2019 2018 U.S. Non-U.S. U.S. Non-U.S. U.S. Non-U.S. Service cost $ 853 $ 3,992 $ 809 $ 3,893 $ 852 $ 4,383 Interest cost 8,132 3,200 10,955 4,037 10,824 4,207 Expected return on plan assets (13,683) (2,415) (16,353) (2,400) (17,414) (2,178) Amortization of prior service cost and actuarial loss 1,940 3,478 2,914 2,373 2,403 2,646 Settlements — 184 15,247 572 — 775 Other — (11) — 956 — — Net periodic benefit (income) cost $ (2,758) $ 8,428 $ 13,572 $ 9,431 $ (3,335) $ 9,833 Pension Settlements In addition to the settlements shown in the table above, the Company recognized $744 of Non-U.S. pension net settlement and curtailment charges due to the divestiture of certain businesses in Europe and India during the year ended December 31, 2020 that are recorded as a reduction to gain on sale of business, net in the consolidated statements of operations. The Company also recognized $836 of Non-U.S. pension settlement charges during the year ended December 31, 2020 that are recorded as restructuring in the consolidated statements of operations. The Company recognized $2,730 of Non-U.S. pension settlement charges due to the divestiture of the Company’s AVS product line during the year ended December 31, 2019. The charges are recorded as a reduction to gain on sale of business, net in the consolidated statements of operations. During the year ended December 31, 2019, the Company undertook an initiative to de-risk pension obligations in the U.S. by purchasing a bulk annuity policy utilizing plan assets, which was designed to match the liabilities of the plan. The resulting non-cash settlement charge of $15,247 was recorded in pension settlement charges, and administrative expenses of $178 were recorded in selling, administration & engineering expenses in the consolidated statements of operations. As a result of the settlement, the Company’s overall projected benefit obligation as of December 31, 2019 was reduced by $58,198. Plan Assumptions Weighted average assumptions used to determine benefit obligations as of December 31, 2020 and 2019 were as follows: 2020 2019 U.S. Non-U.S. U.S. Non-U.S. Discount rate 2.48 % 1.36 % 3.28 % 1.79 % Rate of compensation increase N/A 1.23 % N/A 1.33 % Cash balance interest credit rate 4.50 % N/A 4.50 % N/A Weighted average assumptions used to determine net periodic benefit costs for the years ended December 31, 2020, 2019 and 2018 were as follows: 2020 2019 2018 U.S. Non-U.S. U.S. Non-U.S. U.S. Non-U.S. Discount rate 3.28 % 2.33 % 4.25 % 2.40 % 3.55 % 2.17 % Expected return on plan assets 5.75 % 3.73 % 6.50 % 4.63 % 6.50 % 5.82 % Rate of compensation increase N/A 3.99 % N/A 3.31 % N/A 3.17 % To develop the expected return on plan assets assumption, the Company considered the historical returns and the future expected returns for each asset class, as well as the target asset allocation of the pension portfolio. As the U.S. plans are frozen, the rate of compensation increase was not applicable in determining net periodic benefit cost. Plan Assets The goals and investment objectives of the asset strategy are to ensure that there is an adequate level of assets to meet benefit obligations to participants and retirees over the life of the participants and maintain liquidity in the plan assets sufficient to cover monthly benefit obligations. Risk is managed by investing in a broad range of investment vehicles, e.g., equity mutual funds, bond mutual funds, real estate mutual funds, hedge funds, etc. There are no equity securities of the Company in the equity asset category. Investments in equity securities and debt securities are valued at fair value using a market approach and observable inputs, such as quoted market prices in active markets (Level 1). Investments in balanced funds are valued at fair value using a market approach and inputs that are primarily directly or indirectly observable (Level 2). Investments in equity securities and balanced funds in which the Company holds participation units in a fund, the net asset value of which is based on the underlying assets and liabilities of the respective fund, are considered an unobservable input (Level 3). Investments in real estate funds are primarily valued at net asset value depending on the investment. The fair value of the Company’s pension plan assets by category using the three-level hierarchy (see Note 12. “Fair Value Measurements and Financial Instruments”) as of December 31, 2020 and 2019 was as follows: 2020 Level 1 Level 2 Assets measured at NAV (1) Total Equity funds $ 18,218 $ 16,647 $ — $ 34,865 Equity funds measured at net asset value — — 117,309 117,309 Bond funds — 37,901 — 37,901 Bond funds measured at net asset value — — 104,880 104,880 Real estate measured at net asset value — — 25,070 25,070 Cash and cash equivalents 1,866 — — 1,866 Total $ 20,084 $ 54,548 $ 247,259 $ 321,891 2019 Level 1 Level 2 Assets measured at NAV (1) Total Equity funds $ 16,613 $ 20,126 $ — $ 36,739 Equity funds measured at net asset value — — 101,053 101,053 Bond funds — 34,680 — 34,680 Bond funds measured at net asset value — — 98,967 98,967 Real estate measured at net asset value — — 25,425 25,425 Cash and cash equivalents 2,555 — — 2,555 Total $ 19,168 $ 54,806 $ 225,445 $ 299,419 (1) Certain assets that are measured at fair value using the NAV per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. These assets are included in this table to present total pension plan assets at fair value. There were no transfers of Level 3 assets and no Level 3 assets in the ending balance for the years ended December 31, 2020 and December 31, 2019. Expected Future Benefit Payments The Company estimates its benefit payments for domestic and foreign pension plans during the next ten years to be as follows: Years Ending December 31, U.S. Non-U.S. Total 2021 $ 17,250 $ 6,196 $ 23,446 2022 15,775 6,253 22,028 2023 14,700 28,144 42,844 2024 15,400 7,896 23,296 2025 15,134 8,004 23,138 2026 - 2030 75,540 42,708 118,248 Contributions

Retirement Benefits [Abstract]
Postretirement Benefits Other Than Pensions	Postretirement Benefits Other Than Pensions The Company provides certain retiree health care and life insurance benefits covering certain U.S. salaried and hourly employees and employees in Canada. Employees are generally eligible for benefits upon retirement and completion of a specified number of years of creditable service. The Company’s policy is to fund the cost of these postretirement benefits as these benefits become payable.

The Act reduced the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018. The Act required companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously deferred. In 2018 and 2017, the Company recorded tax expense related to the enactment-date effects of the Act that included recording the one-time transition tax liability related to undistributed earnings of certain foreign subsidiaries that were not previously taxed and adjusting deferred tax assets and liabilities. Our accounting for the income tax effects of the Act was complete as of December 31, 2018. Additionally, on March 27, 2020 the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted into law. The CARES Act allows net operating losses generated by the Company to be carried back up to five years at the tax rates in effect during those periods, rather than carried forward at current federal tax rates of 21%. The Company has included a $27,844 benefit for this CARES Act provision in the period ended December 31, 2020. Nonrecurring permanent items in 2020 were the result of the divestiture of our European rubber, fluid transfer, and specialty sealing businesses as well as our Indian operation, including a worthless security deduction and in 2019 a result of the sale of the AVS product line. Deferred tax assets and liabilities reflect the estimated tax effect of accumulated temporary differences between the basis of assets and liabilities for tax and financial reporting purposes, as well as net operating losses, tax credit and other carryforwards. Significant components of the Company’s deferred tax assets and liabilities as of December 31, 2020 and 2019 were as follows: 2020 2019 Deferred tax assets: Pension, postretirement and other benefits $ 53,229 $ 48,589 Capitalized expenditures 14,411 2,908 Net operating loss and tax credit carryforwards 215,980 167,719 Operating lease 26,160 20,817 All other items 53,290 53,614 Total deferred tax assets 363,070 293,647 Deferred tax liabilities: Property, plant and equipment (29,415) (19,479) Operating lease right-of-use (26,160) (20,817) All other items (15,597) (12,680) Total deferred tax liabilities (71,172) (52,976) Valuation allowances (234,425) (194,794) Net deferred tax assets $ 57,473 $ 45,877 As of December 31, 2020, the Company’s foreign subsidiaries, primarily in France, Brazil, Italy and Germany, had operating loss carryforwards aggregating $520,000, with indefinite expiration periods. Other foreign subsidiaries in China, Mexico, Netherlands, Spain, Czech Republic and Korea had operating losses aggregating $263,000, with expiration dates beginning in 2021. The Company has research tax credit carryforwards and foreign tax credit carryforwards totaling $20,800 in the U.S. with expiration dates beginning in 2029. The Company and its domestic subsidiaries have anticipated tax benefits of state net operating losses and credit carryforwards of $10,400 with expiration dates beginning in 2021. As of December 31, 2020, the Company has consolidated deferred tax assets of $363,070, of which $62,535 relate to the U.S. federal jurisdiction, with valuation allowances of $234,425 related to tax losses, credit carryforwards, and other deferred tax assets in certain foreign and U.S. state jurisdictions. The Company’s valuation allowance increased in 2020 primarily from current year losses generated in certain foreign jurisdictions as well as new valuation allowances in additional foreign and U.S. state jurisdictions. Current and future provision for income taxes is significantly impacted by the initial recognition of and changes in valuation allowances in certain countries. The Company intends to maintain these allowances until it is more likely than not that the deferred tax assets will be realized. In the future, provision for income taxes will include no tax benefit with respect to losses incurred and no tax expense with respect to income generated in these countries until the respective valuation allowance is eliminated. As of December 31, 2020, no material deferred income taxes have been recorded on the undistributed earnings of foreign subsidiaries, since a majority of these earnings will not be taxable upon repatriation to the United States. These earnings will be primarily treated as previously taxed income from either the one time transition tax or GILTI, or they will be offset with a 100% dividends received deduction. The Company has not recorded a deferred tax liability for foreign withholding taxes or state income taxes that may be incurred upon repatriation in the future as such undistributed foreign earnings are considered permanently reinvested or could be remitted with no tax implications. As of December 31, 2020, the Company had $11,272 ($12,550 including interest and penalties) of total unrecognized tax benefits, all of which represented the amount of unrecognized tax benefits that, if recognized, would affect the effective income tax rate. A reconciliation of the beginning and ending amount of unrecognized tax benefits was as follows: 2020 2019 Balance at beginning of period $ 10,123 $ 9,631 Tax positions related to the current period Gross additions 1,115 895 Gross reductions — — Tax positions related to prior years Gross additions 342 — Gross reductions — (52) Settlements (232) — Lapses on statutes of limitations (76) (351) Balance at end of period $ 11,272 $ 10,123 The Company, or one of its subsidiaries, files income tax returns in the United States and other foreign jurisdictions. The Internal Revenue Service completed an examination of the Company’s U.S. income tax returns through 2011. The statute of limitations for U.S. state and local jurisdictions is closed for taxable years ending prior to 2014. The Company’s major foreign jurisdictions are Brazil, Canada, China, France, Germany, Italy, Mexico, and Poland. The Company is no longer subject to income tax examinations in major foreign jurisdictions for years prior to 2016. During the next twelve months, it is reasonably possible that, as a result of audit settlements and the conclusion of current examinations, the Company may decrease the amount of its gross unrecognized tax benefits by approximately $10,229, all of which, if recognized, would impact the effective tax rate. The Company classifies all income tax related interest and penalties as income tax expense. The Company has recorded in liabilities $1,277 and $1,052 as of December 31, 2020 and 2019, respectively, for tax related interest and penalties on its consolidated balance sheet.

As of December 31, 2020, an aggregate of 18,962,894 shares of its common stock were issued, and 16,897,085 shares were outstanding. Holders of shares of common stock are entitled to one vote for each share on each matter on which holders of common stock are entitled to vote. Holders of common stock are entitled to ratably receive dividends and other distributions when, as and if declared by the Company’s board of directors out of assets or funds legally available therefore. The ABL Facility, the Term Loan Facility, the Senior Notes, and the Senior Secured Notes each contain covenants that restrict the Company’s ability to pay dividends or make distributions on the common stock, subject to certain exceptions. In the event of the liquidation, dissolution or winding up of the Company, holders of common stock are entitled to share ratably in the Company assets, if any, remaining after the payment of all the Company’s debts and liabilities. Share Repurchase Program In June 2018, the Company’s Board of Directors approved a common stock repurchase program (the “2018 Program”) authorizing the Company to repurchase, in the aggregate, up to $150.0 million of its outstanding common stock. Under the 2018 Program, repurchases may be made on the open market, through private transactions, accelerated share repurchases, round lot or block transactions on the New York Stock Exchange or otherwise, as determined by management and in accordance with prevailing market conditions and federal securities laws and regulations. The Company expects to fund any future repurchases from cash on hand and future cash flows from operations. The Company is not obligated to acquire a particular amount of securities, and the 2018 Program may be discontinued at any time at the Company’s discretion. The 2018 Program was effective beginning November 2018. As of December 31, 2020, the Company had approximately $98,720 of repurchase authorization under the 2018 Program. The Company did not make any repurchases during the year ended December 31, 2020. 2019 Repurchases In May 2019, the Company entered into an accelerated share repurchase (“ASR”) agreement with a third-party financial institution to repurchase the Company’s common stock pursuant to the 2018 Program. Under the ASR agreement, the Company made an up-front payment of $30,000 and received an initial delivery of 626,305 shares of its common stock in the second quarter of 2019. The repurchase was completed in the third quarter of 2019 when the Company received an additional 72,875 shares. A total of 699,180 shares were repurchased at a weighted average purchase price of $42.91 per share. In addition to the repurchase under the ASR agreement, during the year ended December 31, 2019, the Company repurchased 85,000 shares at an average purchase price of $69.85 per share, excluding commissions, for a total cost of $5,937.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Share-Based Compensation The Company’s long-term incentive plans allow for the grant of various types of share-based awards to key employees and directors of the Company and its affiliates. The Company generally awards grants on an annual basis. There are 2,300,000 shares of common stock authorized for awards granted under the current plan. Under previous plans, a total of 5,873,103 shares were authorized for awards. The plans provide for the grant of stock options, stock appreciation rights, shares of common stock, restricted stock, restricted stock units (“RSUs”), performance-vested restricted stock units (“PUs”), incentive awards and certain other types of awards to key employees and directors of the Company and its affiliates. The Company measures share-based compensation expense at fair value and recognizes such expense on a straight-line basis over the vesting period of the share-based employee awards. The compensation expense related to stock options, restricted stock and performance units granted to key employees and directors of the Company, which is quantified below, does not represent payments actually made to these employees. Rather, the amounts represent the non-cash compensation expense recognized by the Company in connection with these awards for financial reporting purposes. The actual value of these awards to the recipients will depend on the trading price of the Company’s stock when the awards vest. In accordance with the Company’s long-term incentive plans, share-based compensation awards that settle in shares of Company stock may be delivered on a gross settlement basis or a net settlement basis, as determined by the recipient. Share-based compensation expense (income) was as follows: Year Ended December 31, 2020 2019 2018 PUs $ 916 $ 277 $ (3,925) RSUs 6,994 8,432 9,241 Stock options 2,525 3,156 3,204 Total $ 10,435 $ 11,865 $ 8,520 Stock Options Stock option awards are granted at the fair market value of the Company’s stock price at the date of the grant and have a 10 year term. The stock option grants vest over three years from the date of grant. Stock option transactions and related information for the year ended December 31, 2020 was as follows: Options Weighted Average Exercise Price Weighted Average Remaining Contractual Life (Years) Aggregate Intrinsic Value Outstanding as of January 1, 2020 548,770 $ 77.68 Granted 233,732 $ 25.19 Exercised — $ — Forfeited (21,757) $ 49.53 Expired (19,326) $ 51.62 Outstanding as of December 31, 2020 741,419 $ 62.64 6.1 $ 2,103 Exercisable as of December 31, 2020 408,316 $ 78.37 5.0 $ — The weighted-average grant date fair value of stock options granted during the years ended December 31, 2020, 2019 and 2018 was $8.85, $24.22 and $36.22, respectively. There were no stock options exercised during the year ended December 31, 2020. The total intrinsic value of stock options exercised during the years ended December 31, 2019 and 2018 was $243 and $12,422, respectively. As of December 31, 2020, unrecognized compensation expense for stock options amounted to $2,728. Such cost is expected to be recognized over a weighted average period of approximately 1.7 years. The fair value of the options was estimated at the date of the grant using the Black-Scholes option pricing model. Expected volatility was based on the historical volatility of the Company’s common stock. The expected option life was calculated using the simplified method. The risk-free rate is based on the U.S. Treasury zero-coupon issues with a term equal to the expected option life on the date the stock options were granted. The fair value of each option was estimated using the following assumptions: 2020 2019 2018 Expected volatility 33.74% 29.48% - 31.10% 27.17% - 27.19% Dividend yield 0.00 % 0.00 % 0.00 % Expected option life - years 6.0 6.0 6.0 Risk-free rate 1.5% 1.8% - 2.5% 2.6% Restricted Stock and Restricted Stock Units The fair value of the restricted stock and restricted stock units is determined based on the closing price of the common stock on the date of grant. The restricted stock and restricted stock units vest over one Restricted stock and restricted stock units transactions and related information for the year ended December 31, 2020 was as follows: Restricted Stock and Restricted Units Weighted Average Grant Date Fair Value Non-vested as of January 1, 2020 332,981 $ 83.60 Granted 169,038 $ 17.62 Vested (86,976) $ 99.41 Forfeited (29,408) $ 73.75 Non-vested as of December 31, 2020 385,635 $ 54.10 The weighted-average grant date fair value of restricted stock and restricted stock units granted during the years ended December 31, 2020, 2019 and 2018 was $17.62, $66.12 and $110.34, respectively. The total fair value of restricted stock and restricted stock units vested during the years ended December 31, 2020, 2019 and 2018 was $7,786, $9,859 and $7,418, respectively. As of December 31, 2020, unrecognized compensation expense for restricted stock and restricted stock units amounted to $5,973. Such cost is expected to be recognized over a weighted-average period of approximately 1.2 years. Performance-Vested Restricted Stock Units The actual number of performance units that will vest depends on the Company’s achievement of target performance goals related to the Company’s ROIC and total shareholder return over a performance period, which may range from 0% to 200% of the target award amount. The PUs cliff vest at the end of their three-year performance period or vest ratably over three years after their initial two-year performance period. PUs that are expected to be settled in shares of the Company’s common stock are accounted for as equity awards, and the fair value is determined based on the closing price of the common stock on the date of grant. PUs that are expected to be settled in cash are accounted for as liability awards. A summary of activity for performance-vested restricted stock units transactions and related information for the year ended December 31, 2020 was as follows: Performance Units Weighted Average Grant Date Fair Value Non-vested as of January 1, 2020 194,053 $ 93.86 Granted 130,346 $ 10.10 Vested (48,772) $ 107.50 Forfeited (17,387) $ 57.57 Non-vested as of December 31, 2020 258,240 $ 51.45 The weighted-average grant date fair value of performance units granted during the years ended December 31, 2020, 2019 and 2018 was $10.10, $78.41 and $110.40, respectively. The total fair value of PUs vested during the years ended December 31, 2020, 2019 and 2018 was $5,243, $5,450, and $8,256, respectively. Actual payout of units vested was 0% during the year ended December 31, 2020 and no cash was paid to settle PUs during the year ended December 31, 2020. Cash paid to settle PUs during the years ended December 31, 2019 and 2018 was $3,345 and $13,302, respectively. As of December 31, 2020, unrecognized compensation expense for the PUs granted in 2020 was $1,448. Such cost is expected to be recognized over a weighted-average period of approximately 2.0 years. The fair value of the performance units is estimated using a Monte Carlo simulation. Expected volatility was calculated based on historical stock price volatility over the previous year. The risk-free rate was based on the U.S. Treasury yield curve, generally represented by U.S. Treasury securities, with a term equal to the expected life of the performance units. The dividend yield was assumed to be zero based on Company’s historical patterns and future expectation. The fair value of the performance units granted in 2020 was estimated using the following assumptions: 2020 Expected volatility 116.60 % Dividend yield 0.00 % Risk-free rate 0.10 %

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, 2020, 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. 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, 2020 and 2019, the Company had $13,302 and $6,104, 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 have a material adverse effect on the Company’s financial condition, such costs may be material to the Company’s financial statements in the future.

Foreign currency	Foreign Currency – The financial statements of foreign subsidiaries are translated to U.S. dollars at the end-of-period exchange rates for assets and liabilities and at a weighted average exchange rate for each period for revenues and expenses. Translation adjustments for those subsidiaries whose local currency is their functional currency are recorded as a component of accumulated other comprehensive income (loss) in stockholders’ equity (“AOCI”). Transaction related gains and losses arising from fluctuations in currency exchange rates on transactions denominated in currencies other than the functional currency are recognized in earnings as incurred, except for those intercompany balances which are designated as long-term.
Cash and cash equivalents	Cash and Cash Equivalents – The Company considers highly liquid investments with an original maturity of three months or less to be cash equivalents.
Accounts receivable	Accounts Receivable – The Company records trade accounts receivable when revenue is recorded in accordance with its revenue recognition policy and relieves accounts receivable when payments are received from customers. Accounts receivable are written off when it is apparent such amounts are not collectible. Generally, the Company does not require collateral for its accounts receivable, nor is interest charged on accounts receivable balances.
Allowance for doubtful accounts	Allowance for Credit Losses – An allowance for credit losses is established through charges to the provision for credit losses when it is probable that the outstanding receivable or reimbursable tooling will not be collected. The Company evaluates the adequacy of the allowance for credit losses on a periodic basis, including historical trends in collections and write-offs, management’s judgment of the probability of collecting accounts and management’s evaluation of business risk. This evaluation is inherently subjective, as it requires estimates that are susceptible to revision as more information becomes available. The allowance for credit losses was $7,100 and $9,149 as of December 31, 2020 and 2019, respectively.
Advertising expense	Advertising Expense – Expenses incurred for advertising are generally expensed when incurred. Advertising expense was $425, $711 and $1,493 for the years ended December 31, 2020, 2019 and 2018, respectively.
Inventories	Inventories – Inventories are valued at lower of cost or net realizable value. Cost is determined using the first-in, first-out method. Finished goods and work-in-process inventories include material, labor and manufacturing overhead costs. The Company records inventory reserves for inventory in excess of production and/or forecasted requirements and for obsolete inventory. December 31, 2020 2019 Finished goods $ 39,136 $ 57,070 Work in process 35,477 33,753 Raw materials and supplies 69,129 52,616 $ 143,742 $ 143,439
Derivative financial instruments	Derivative Financial Instruments – Derivative financial instruments are utilized by the Company to reduce foreign currency exchange. The Company has established policies and procedures for risk assessment and the approval, reporting and monitoring of derivative financial instrument activities. On the date the derivative is established, the Company designates the derivative as either a fair value hedge, a cash flow hedge or a net investment hedge in accordance with its established policy. The Company does not enter into derivative financial instruments for trading or speculative purposes.
Income taxes	Income Taxes – Deferred tax assets or liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using enacted tax laws and rates. A valuation allowance is provided on deferred tax assets if the Company determines that it is more likely than not that the asset will not be realized.
Long-lived assets	Long-lived Assets – Property, plant and equipment are recorded at cost and depreciated using primarily the straight-line method over estimated useful lives. Leasehold improvements are amortized over the expected life of the asset or term of the lease, whichever is shorter. Intangibles with finite lives, which include technology and customer relationships, are amortized over estimated useful lives. The Company evaluates the recoverability of long-lived assets when events and circumstances indicate that the assets may be impaired and the undiscounted net cash flows estimated to be generated by those assets are less than their carrying value. If the net carrying value exceeds the fair value, an impairment loss exists and is calculated based on either estimated salvage value or estimated orderly liquidation value.
Pre-production costs related to long term supply arrangements	Pre-production Costs Related to Long Term Supply Arrangements – Costs for molds, dies and other tools owned by the Company to produce products under long-term supply arrangements are recorded at cost in property, plant and equipment and amortized over the lesser of three
Goodwill	Goodwill – The Company tests goodwill for impairment on an annual basis in the fourth quarter, or more frequently if an event occurs or circumstances indicate the carrying amount may be impaired. Goodwill impairment testing is performed at the reporting unit level. The impairment test involves first qualitatively assessing goodwill for impairment. If the qualitative assessment is not met, a quantitative assessment is performed by comparing the estimated fair value of each reporting unit to its carrying value. If the carrying value exceeds the fair value, an impairment charge is recorded based on that difference. The Company’s organizational structure changed on January 1, 2020. See Note 24. “Business Segments” for further detail on this reorganization of our business. The change in organizational structure of the business represented a triggering event to test goodwill for impairment as of January 1, 2020. No impairment was identified as a result of completing the goodwill impairment test. Other than the change in organizational structure event noted above, there were no other indicators of potential impairment during the year ended December 31, 2020.
Business Combinations Policy [Policy Text Block]	Business Combinations – The purchase price of an acquired business is allocated to its identifiable assets and liabilities based on estimated fair values. The excess of the purchase price over the amount allocated to the assets and liabilities, if any, is recorded as goodwill. Determining the fair values of assets acquired and liabilities assumed requires management’s judgment, the utilization of independent appraisal firms and often involves the use of significant estimates and assumptions with respect to the timing and amount of future cash flows, market rate assumptions, actuarial assumptions, and appropriate discount rates, among other items.
Revenue recognition and sales commitments	Revenue Recognition and Sales Commitments – In accordance with ASC 606, Revenue from Contracts with Customers , revenue is recognized when the performance obligations are satisfied. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC 606. The Company has one major performance obligation category: manufactured parts. A contract’s transaction price is allocated to each distinct performance obligation and recognized when the performance obligation is satisfied. The Company’s contracts may include multiple performance obligations. For such contracts, the Company generally allocates the contract’s transaction price to each performance obligation based on the purchase order or other arranged pricing. Revenue is recognized for manufactured parts at a point in time, generally when products are shipped or delivered. The point at which revenue is recognized often depends on the shipping terms. The Company usually enters into agreements with customers to produce products at the beginning of a vehicle’s life. Blanket purchase orders received from customers and related documents generally establish the annual terms, including pricing, related to a vehicle model. Although purchase orders do not usually specify quantities, fulfillment of customers’ purchasing requirements can be the Company’s obligation for the entire production life of the vehicle. These agreements generally may be terminated by the Company’s customer at any time, but such cancellations have historically been minimal. Customers typically pay for parts based on customary business practices with payment terms generally between 30 and 90 days. The Company has no significant financing arrangements with customers. The Company applies the optional exemption to forgo disclosing information about its remaining performance obligations because its contracts usually have an original expected duration of one year or less. It also applies an accounting policy to treat shipping and handling costs that are incurred after revenue is recognizable as a fulfillment activity by expensing such costs as incurred, instead of as a separate performance obligation. This is consistent with the Company’s historical accounting practices. The Company has chosen to present revenue net of sales and other similar taxes, which is also consistent with its historical accounting practices.
Shipping and Handling Cost, Policy [Policy Text Block]	Shipping and Handling – Amounts billed to customers related to shipping and handling are included in sales in the Company’s consolidated statements of operations. Shipping and handling costs are included in cost of products sold in the Company’s consolidated statements of operations.
Research and development	Research and Development – Engineering, research and development, and program management costs are charged to selling, administration and engineering expenses as incurred and totaled $101,607, $114,854 and $122,529 for the years ended December 31, 2020, 2019 and 2018, respectively.
Stock-based compensation	Share-based Compensation – The Company measures share-based compensation expense at fair value and generally recognizes such expenses on a straight-line basis over the vesting period of the share-based employee awards. See Note 21. “Share-Based Compensation” for additional information.
Use of estimates	Use of Estimates – The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect amounts reflected in the consolidated financial statements, as well as disclosure of contingent assets and liabilities. Considerable judgment is often involved in making such estimates, and the use of different assumptions could result in different conclusions. Management believes its assumptions and estimates are reasonable and appropriate. However, actual results could differ from those estimates.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Adopted Accounting Pronouncements The Company adopted the following Accounting Standards Updates (“ASU”) in 2020: ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) On January 1, 2020, the Company adopted Accounting Standards Codification (“ASC”) 326, Financial Instruments – Credit Losses, and all related amendments using the modified retrospective method whereby the cumulative effect of adopting the standard was recognized in equity at the date of initial application. Comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The most prominent among the changes in the standard is the consideration of losses not yet incurred, but expected, based on current conditions and future forecasts. Adoption of the new standard resulted in an immaterial increase in the allowance for credit losses, which decreased the tooling receivable on the Company’s condensed consolidated balance sheet in 2020. The increase in credit loss expense was recorded as an adjustment to the opening balance of retained earnings. Adoption of the new standard had no impact on the Company’s condensed consolidated statement of operations or on cash provided by (used in) operating, financing or investing activities on its condensed consolidated cash flow statements. The cumulative effects of the changes made to the Company’s condensed consolidated balance sheet as of January 1, 2020 were as follows: Balance as of December 31, 2019 Adjustments due to adoption of ASC 326 Balance as of January 1, 2020 Tooling receivable, net $ 148,175 $ (1,573) $ 146,602 Retained earnings 619,448 (1,573) 617,875 The Company adopted the recently issued accounting pronouncement summarized as follows, which had an immaterial impact on its consolidated financial statements and disclosures: Standard Description Impact Effective Date ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans Modifies the disclosure requirements for ASC Topic 715 by removing and modifying existing disclosure requirements while also adding new disclosures. Adoption of this standard resulted in additional pension disclosures while also removing certain other disclosures. Specifically, the weighted-average interest crediting rate for the U.S. cash balance plan was added while accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year and the effects of a one-percentage-point change in the assumed health care cost trend rate were removed. December 31, 2020 The Company adopted the following ASUs in 2020, which did not have a material impact on its consolidated financial statements: Standard Description Effective Date ASU 2018-15 , Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract Aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. January 1, 2020 ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting Provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. January 1, 2020 Recently Issued Accounting Pronouncements The Company considered the recently issued accounting pronouncements summarized as follows, which will not have a material impact on its consolidated financial statements or disclosures: Standard Description Effective Date ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes Modifies ASC Topic 740 by removing certain exceptions and amending existing guidance in order to simplify the accounting for income taxes. January 1, 2021 ASU 2021-01, Reference Rate Reform (Topic 848): Scope Clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition and tailors the existing guidance to derivative instruments affected by the discounting transition.
