Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Organization - Commercial Vehicle Group, Inc. (through its subsidiaries) is a leading supplier of electrical wire harnesses, seating systems, and a full range of other cab related products for the global commercial vehicle markets, including the medium- and heavy-duty truck, medium-and heavy-construction vehicle, military, bus, agriculture, specialty transportation, mining, industrial equipment and off-road recreational markets. We are differentiated from automotive industry suppliers by our ability to manufacture low volume, customized products on a sequenced basis to meet the requirements of our customers. We believe our products are used by a majority of the North American MD/HD Truck and many medium- and heavy-duty construction vehicle original equipment manufacturers (“OEMs”), and to a lesser extent other makers of industrial equipment. We have manufacturing operations in the United States, Mexico, China, United Kingdom, Czech Republic, Ukraine, Thailand, India and Australia. Our products are primarily sold in North America, Europe, and the Asia-Pacific region. We report our financial results by business segment; more specifically, Electrical Systems and Global Seating. The Company’s Chief Operating Decision Maker (“CODM”), its President and Chief Executive Officer, reviews financial information for these two reportable segments and makes decisions regarding the allocation of resources based on these segments. See Note 12 of the Notes to Consolidated Financial Statements for more information. Unless otherwise indicated, all amounts are in thousands, except share and per share amounts. Principles of Consolidation - The accompanying consolidated financial statements include the accounts of our wholly-owned or controlled subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include allowance for doubtful accounts, inventory reserves, goodwill, intangible and long-lived assets, pension and other post-retirement benefits, product warranty reserves, litigation reserves, and income tax valuation allowances. Actual results may differ materially from those estimates. Cash - Cash consists of deposits with high credit-quality financial institutions. Accounts Receivable - Trade accounts receivable are stated at current value less allowances, which approximates fair value. We review our receivables on an ongoing basis to ensure that they are properly valued and collectible. The allowance for doubtful accounts is used to record the estimated risk of loss related to our customers’ inability to pay. This allowance is maintained at a level that we consider appropriate based on factors that affect collectability, such as the financial health of our customers, historical trends of charge-offs and recoveries and current economic market conditions. As we monitor our receivables, we identify customers that may have payment problems and adjust the allowance accordingly, with the offset to selling, general and administrative expense. Account balances are charged off against the allowance when recovery is considered remote. Inventories - Inventories are valued at the lower of first-in, first-out cost or market and are measured at the lower of cost or net realizable value. Inventory quantities on-hand are regularly reviewed and when necessary provisions for excess and obsolete inventory are recorded based primarily on our estimated production requirements, taking into consideration expected market volumes and future potential use. Property, Plant and Equipment - Property, plant and equipment are stated at cost, net of accumulated depreciation. For financial reporting purposes, depreciation is computed using the straight-line method over the following estimated useful lives: Buildings and improvements 15 to 40 years Machinery and equipment 3 to 20 years Tools and dies 3 to 7 years Computer hardware and software 3 to 5 years Expenditures for maintenance and repairs are charged to expense as incurred. Expenditures for major betterments and renewals that extend the useful lives of property, plant and equipment are capitalized and depreciated over the remaining useful lives of the asset. When assets are retired or sold, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized in the results of operations. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the improvements or the term of the lease, whichever is shorter. Accelerated depreciation methods are used for tax reporting purposes. Depreciation expense for property, plant and equipment for each of the years ended December 31, 2019 , 2018 and 2017 was $13.6 million , $14.0 million and $13.9 million , respectively. We review long-lived assets for recoverability whenever events or changes in circumstances indicate that carrying amounts of an asset group may not be recoverable. Our asset groups are established by determining the lowest level of cash flows available. If the estimated undiscounted cash flows are less than the carrying amounts of such assets, we recognize an impairment loss in an amount necessary to write down the assets to fair value as estimated from expected future discounted cash flows. Estimating the fair value of these assets is judgmental in nature and involves the use of significant estimates and assumptions. We base our fair value estimates on assumptions we believe to be reasonable, but that are inherently uncertain. Revenue Recognition - We recognize revenue when our performance obligation has been satisfied and control of products has been transferred to a customer, which typically occurs upon shipment. Revenue is measured based on the amount of consideration we expect to receive in exchange for the transfer of goods or services. Returns and allowances are used to record estimates of returns or allowances resulting from quality, delivery, discounts or other issues affecting the value of receivables. This amount is estimated based on historical trends and current market conditions, with the offset to revenues. Income Taxes - We recognize deferred tax assets and liabilities for the expected future tax consequences of events that have been included in our financial statements or tax returns. Deferred tax assets and liabilities are determined based on the difference between the financial statements and tax basis of assets and liabilities based on enacted tax laws and rates expected to be in place when the deferred tax items are realized. In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that a portion of the deferred tax assets will not be realized. We provide a valuation allowance for deferred tax assets when it is more likely than not that a portion of such deferred tax assets will not be realized. We evaluate tax positions for recognition by determining, based on the weight of available evidence, whether it is more likely than not the position will be sustained upon audit. Any interest and penalties related to our uncertain tax positions are recognized in income tax expense. Comprehensive Income (Loss) - Comprehensive income (loss) reflects the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources including foreign currency translation, derivative instruments and pension and other post-retirement adjustments. See Note 18 for a rollforward of activity in accumulated comprehensive loss. Fair Value of Financial Instruments - The fair value framework requires the categorization of assets and liabilities into three levels based upon the assumptions (i.e., inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. The three levels are defined as follows: Level 1 - Unadjusted quoted prices in active markets for identical assets and liabilities. Level 2 - Observable inputs other than those included in Level 1. For example, quoted prices for similar assets or liabilities in active markets and inactive markets. Level 3 - Significant unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability. Concentrations of Credit Risk - Financial instruments that potentially subject us to concentrations of credit risk consist primarily of accounts receivable. We sell products to various companies throughout the world in the ordinary course of business. We routinely assess the financial strength of our customers and maintain allowances for anticipated losses. As of December 31, 2019 and 2018 , receivables from our largest customers, A.B. Volvo, Daimler Trucks, Caterpillar, Navistar, John Deere and PACCAR, represented approximately 62% and 66% of total receivables, respectively. Foreign Currency Translation - Our functional currency is the local currency. Accordingly, all assets and liabilities of our foreign subsidiaries are translated using exchange rates in effect at the end of the period; revenue and costs are translated using average exchange rates for the period. The related translation adjustments are reported in accumulated other comprehensive income (loss) in stockholders’ equity. Translation gains and losses arising from transactions denominated in a currency other than the functional currency of the entity are included in the results of operations. Foreign Currency Forward Exchange Contracts - We use forward exchange contracts to hedge certain foreign currency transaction exposures. We estimate our projected revenues and purchases in certain foreign currencies or locations and hedge a portion of the anticipated long or short position. The contracts typically run from one month to eighteen months. All forward foreign exchange contracts that are not designated as hedging instruments have been marked-to-market and the fair value of contracts recorded in the Consolidated Balance Sheets with the offsetting non-cash gain or loss recorded in our Consolidated Statements of Operations. For forward contracts that are designated as hedging instruments, the gains and losses are recorded in accumulated other comprehensive income (loss) and recognized in the Consolidated Statement of Operations when the contracts are settled. We do not hold or issue foreign exchange options or forward contracts for trading purposes. Interest Rate Swap Agreement - We use an interest rate swap agreement to fix the interest rate on a portion of our variable interest debt thereby reducing exposure to interest rate changes. The interest rate swap agreement was not designated as a hedging instrument; therefore, the interest rate swap agreement has been marked-to-market and the fair value of the agreement recorded in the Consolidated Balance Sheets with the offsetting gain or loss recorded in interest and other expense in our Consolidated Statements of Operations. Recently Issued Accounting Pronouncements In July 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2019-07, "Codification Updates to SEC Sections". ASU No. 2019-07 clarifies or improves the disclosure and presentation requirements of a variety of codification topics by aligning them with the SEC's regulations, thereby eliminating redundancies. This ASU is effective upon issuance and did not have a significant impact on the Company's consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326)". The ASU requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. The FASB subsequently issued ASU No. 2018-19, "Codification Improvements to Topic 326: Financial Instruments - Credit Losses", in November 2018 which provided further guidance on assessment of receivables for operating leases. ASU No. 2019-04, "Codification Improvements to Topic 326, Topic 815 and Topic 825" and ASU No. 2019-05, "Targeted Transition Relief", that were issued in April and May of 2019 do not materially impact the Company. In November 2019, the FASB issued ASU No. 2019-11, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses", which further clarified and improved the Codification to make it easier to understand and apply. The Company anticipates ASU 2016-13, ASU 2018-19 and ASU 2019-11 will apply to its trade receivables and will not have a material impact on the reported value of such receivables. We expect to implement ASU No. 2016-13, 2018-19 and 2019-11 on the effective date of January 1, 2020. In December 2019, the FASB issued ASU No. 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes". The ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and otherwise clarifies and amends existing guidance. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020. We are evaluating the effect this ASU will have on the Company. Accounting Pronouncements Implemented During the Year Ended December 31, 2019 In June 2018, the FASB issued ASU No. 2018-07, "Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting". The ASU changed the measurement date for determining the fair value of share awards to nonemployees to the grant date and requires the consideration of the probability of satisfying performance obligations in assessing the awards. The ASU did not have a material impact on our recognition of share-based payments for nonemployees. Lease Accounting Guidance In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" followed by ASU No. 2018-11, "Leases (Topic 842): Targeted Improvements", issued in July 2018. These ASUs are intended to increase transparency and comparability among companies by recognizing lease assets and liabilities and disclosing key information about leasing arrangements. ASU 2016-02 was adopted by the Company on January 1, 2019. In accordance with Topic 842, we elected not to recognize lease assets and lease liabilities for leases with a term of twelve months or less and elected to not separate lease and non-lease components. We elected the transition method option under ASU 2018-11 with the package of practical expedients that permits the Company to: (a) not reassess whether expired or existing contracts contain leases, (b) not reassess lease classification for existing or expired leases and (c) not consider whether previously capitalized initial direct costs would be appropriate under the new standard. We recorded a right-of-use asset of $21.2 million and a lease liability of $22.2 million upon adoption. We also elected the option to apply the new leasing standard on the date of adoption and recognize a cumulative-effect transition adjustment to the opening balance of retained earnings in the period of adoption resulting in a cumulative effect as of January 1, 2019 of $0.1 million . Refer to Note 6 for further details.

Restatement of Previously Issue

Accounting Changes and Error Corrections [Abstract]
Restatement of Previously Issued Consolidated Financial Statements	Restatement of Previously Issued Consolidated Financial Statements Restatement Background On March 12, 2020, the Audit Committee of the Board of Directors (the “Audit Committee”) of the Company, after considering the recommendations of management, and discussing such recommendations with outside SEC counsel, concluded that our 2018 Financial Statements, included in our Annual Report on Form 10-K as of and for the fiscal year ended December 31, 2018 (the “2018 Annual Report”), and our unaudited consolidated financial statements as of and for the quarterly periods ended March 31, 2019 and 2018, June 30, 2019 and 2018, and September 30, 2019 and 2018, included in our Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2019, June 30, 2019 and September 30, 2019 (the "2019 Quarterly Reports”), should no longer be relied upon due to misstatements that are described in greater detail below, and that we would restate such financial statements to make the necessary accounting corrections. During the preparation of our Annual Report on Form 10-K for the year ended December 31, 2019 (the “2019 Annual Report”), we noted a potential overstatement of the prepaid production tooling account of our vehicle cab structures manufacturing facility (presented in other current assets in the consolidated balance sheets). An investigation was conducted, under the direction of the Audit Committee, by external counsel with the assistance of a forensic accounting firm. As a result of the investigation, the Company concluded that the misstatements in our consolidated financial statements for the periods identified above were due to a former employee preparing manual journal entries to understate cost of revenues by improperly capitalizing certain manufacturing expenses, primarily in the prepaid production tooling account. The former employee made intentional misrepresentations during the investigation. During the course of, and as a result of, the investigation, the Company terminated the former employee and has taken additional personnel actions. The Company evaluated the materiality of these errors both qualitatively and quantitatively in accordance with Staff Accounting Bulletin (“SAB”) No. 99, Materiality and SAB No. 108, Considering the Effects of Prior Year Misstatements in Current Year Financial Statements , and determined the effect of these corrections was material to the consolidated financial statements as of and for the year ended December 31, 2018 and the quarterly periods ended March 31, 2019 and 2018, June 30, 2019 and 2018, and September 30, 2019 and 2018. As a result of the material misstatements, we have restated our consolidated financial statements as of and for the year ended December 31, 2018 and our unaudited consolidated financial statements as of and for the quarterly periods ended March 31, 2019 and 2018, June 30, 2019 and 2018, and September 30, 2019 and 2018, in accordance with ASC 250, Accounting Changes and Error Corrections (the "Restated Financial Statements"). Based on the analysis noted above, the correction of errors resulting from the former employee's actions noted above were immaterial to the previously reported consolidated financial statements as of and for the year ended December 31, 2017 (the “2017 Annual Report”). The amounts in the 2017 Annual Report have been revised to reflect the correction of these errors. In addition to the adjustments to correct the understatement of cost of revenues and impacted balance sheet accounts, we also made an adjustment to correct an overstatement of property, plant and equipment (“PPE”) that was no longer in service as of the year ended December 31, 2016, and was unrelated to the correction of errors resulting from the former employee's actions. The Company evaluated this error in accordance with SAB 99 and 108 and concluded that the correction of the PPE error was immaterial to our consolidated financial statements. The restated interim financial information for the relevant unaudited interim financial statements for the quarterly periods ended March 31, 2019 and 2018, June 30, 2019 and 2018, September 30, 2019 and 2018, and December 31, 2018, is included in Note 19. The restatement adjustments and error correction and their impact on previously reported consolidated financial statements are described below. (a) Understatement of cost of revenues and impacted balance sheet accounts - Corrections for the understatement of cost of revenues by improperly capitalizing certain manufacturing expenses. Balance sheet accounts adjusted as a result of the improper capitalization of expenses include other current assets, accounts receivable, net of allowances and construction in progress. (b) Property, plant and equipment, net - We recorded an adjustment for a previously identified property, plant and equipment, net error unrelated to the understatement of cost of revenues and related balance sheet accounts misstatements. This PPE was no longer in service as of and for the year ended December 31, 2016. Summary impact of restatement adjustments and immaterial error correction to previously reported financial information The following tables present the summary impacts of the restatement adjustments and immaterial error correction on our previously reported retained deficit and total stockholders’ equity for the year ended December 31, 2016, and income before provision for income taxes and net income (loss) for the years ended December 31, 2018 and 2017: December 31, 2016 Retained deficit Total Stockholders' Equity As previously reported $ (113,378 ) $ 67,690 Cumulative adjustments (1,855 ) (1,855 ) As adjusted $ (115,233 ) $ 65,835 For the years ended December 31, 2018 2017 Income before income taxes - as previously reported $ 53,508 $ 13,645 Restatement adjustments (4,080 ) — Error corrections 148 (847 ) Income before income taxes - as restated / adjusted $ 49,576 $ 12,798 Net income (loss) - as previously reported $ 44,512 $ (1,705 ) Restatement adjustments (3,135 ) — Error corrections 112 (564 ) Net income (loss) - as restated / adjusted $ 41,489 $ (2,269 ) The following table presents the effect of the error correction on the Company’s consolidated balance sheets for the period indicated: COMMERCIAL VEHICLE GROUP, INC.

Revenue Recognition

Revenue Recognition	12 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Our products include electrical wire harnesses, control panels and assemblies; trim systems and components ("Trim"); cab structures and sleeper boxes; mirrors, wipers and controls; and seats and seating systems ("Seats"). We sell these products into multiple geographic regions including North America, Europe and Asia-Pacific and to multiple customer end markets including MD/HD Truck OEMs, Bus OEMs, Construction OEMs, the aftermarket and other markets. The nature, timing and uncertainty of recognition of revenue and associated cash flows across the varying product lines, geographic regions and customer end markets is substantially consistent. Contractual Arrangements Revenue is measured based on terms and conditions specified in contracts or purchase orders with customers. We have long-term contracts with some customers that govern overall terms and conditions which are accompanied by purchase orders that define specific order quantities and/or price. We have many customers with which we conduct business outlined in purchase orders without a long-term contract. We generally do not have customer contracts with minimum order quantity requirements. Amount and Timing of Revenue Recognition The transaction price is based on the consideration to which the Company will be entitled in exchange for transferring control of a product to the customer. This is defined in a purchase order or in a separate pricing arrangement and represents the stand-alone selling price. Our payment terms vary by customer. None of the Company's business arrangements as of December 31, 2019 , contained a significant financing component. We typically do not have multiple performance obligations requiring us to allocate a transaction price. We recognize revenue at the point in time when we satisfy a performance obligation by transferring control of a product to a customer, usually at a designated shipping point and in accordance with customer specifications. We make estimates for potential customer returns or adjustments based on historical experience, which reduce revenues. Other Matters Shipping and handling costs billed to customers are recorded in revenues and costs associated with outbound freight are generally accounted for as a fulfillment cost and are included in cost of revenues. We generally do not provide for extended warranties or material customer incentives. Our customers typically do not have a general right of return for our products. We had outstanding customer accounts receivable, net of allowances, of $115.1 million as of December 31, 2019 and $133.9 million as of December 31, 2018 . We generally do not have other assets or liabilities associated with customer arrangements. In general, we do not make significant judgments or have variable consideration that impact our recognition of revenue. Refer to Note 12 for revenue disclosures by reportable segments.

Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement At December 31, 2019 , our financial instruments consisted of cash, accounts receivable, accounts payable, accrued liabilities and our revolving credit facility. The carrying value of these instruments approximates fair value as a result of the short duration of such instruments or due to the variability of the interest cost associated with such instruments. Foreign Currency Forward Exchange Contracts. Our derivative assets and liabilities represent foreign exchange contracts that are measured at fair value using observable market inputs such as forward rates, interest rates, our own credit risk and counterparty credit risk. Based on the utilization of these inputs, the derivative assets and liabilities are classified as Level 2. To manage our risk for transactions denominated in Mexican Pesos, we have entered into forward exchange contracts that are designated as cash flow hedge instruments, which are recorded in the Consolidated Balance Sheets at fair value. The gains and losses as a result of the changes in fair value of the hedge contract is deferred in accumulated other comprehensive loss and recognized in cost of revenues in the period the related hedge transactions are recognized. Interest Rate Swap Agreement. To manage our exposure to variable interest rates, we have entered into an agreement (the “Interest Rate Swap Agreement”) with Bank of America, N.A. whereby the Company has agreed to exchange, at a specified interval, the difference between fixed and variable interest amounts calculated by reference to an agreed upon notional principal amount. The Interest Rate Swap Agreement is intended to mitigate the impact of rising interest rates on the Company and covers $80 million of outstanding debt under the senior secured term loan facility. The Company expects this agreement to remain effective during the remaining term of the Interest Rate Swap Agreement and records the impact of the agreement in interest and other expense in the Consolidated Statements of Operations. The fair values of our derivative instruments and contingent consideration measured on a recurring basis as of December 31 and are categorized as follows: 2019 2018 Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Derivative assets Foreign exchange contract 1 $ 464 $ — $ 464 $ — $ 496 $ — $ 496 $ — Interest rate swap agreement 2 $ 150 $ — $ 150 $ — $ 1,131 $ — $ 1,131 $ — Derivative liabilities Interest rate swap agreement 3 $ 995 $ — $ 995 $ — $ — $ — $ — $ — Earnout liability Contingent consideration 5 $ 4,700 $ — $ — $ 4,700 $ — $ — $ — $ — Derivative equity Foreign exchange contract 4 $ 464 $ — $ 464 $ — $ 496 $ — $ 496 $ — 1 Presented in the Consolidated Balance Sheets in other current assets and based on observable market transactions of spot and forward rates. 2 Presented in the Consolidated Balance Sheets in other assets and based on observable market transactions of forward rates. 3 Presented in the Consolidated Balance Sheets in accrued liabilities and other and based on observable market transactions of forward rates. 4 Presented in the Consolidated Balance Sheets in accumulated other comprehensive income (loss) and based on observable market transactions of forward rates. 5 Presented in the Consolidated Balance Sheets in accrued liabilities and other long term liabilities and based on a Monte Carlo valuation model.

The following table summarizes the effect of derivative instruments on the Consolidated Statements of Operations for derivatives not designated as hedging instruments at December 31 : 2019 2018 Location of Gain (Loss) Amount of Gain (Loss) Foreign exchange contracts Cost of Revenues $ 4 $ 607 Interest rate swap agreement Interest and Other Expense $ (1,818 ) $ 785 Long-term Debt . The fair value of long-term debt obligations is based on a fair value model utilizing observable inputs. Based on these inputs, our long-term debt is classified as Level 2. The carrying amounts and fair values of our long-term debt at December 31 are as follows: 2019 2018 Carrying Fair Value Carrying Fair Value Term loan and security agreement 1 $ 156,384 $ 157,983 $ 163,758 $ 161,759 1 Presented in the Consolidated Balance Sheets as the current portion of long-term debt (net of current prepaid debt financing costs of $0.5 million and current original issue discount of $0.6 million ) of $3.3 million and long-term debt (net of long-term prepaid debt financing costs of $1.2 million and long-term original issue discount of $1.3 million ) of $153.1 million . Long-lived Assets. There are no fair value measurements of our long-lived assets and definite-lived intangible assets measured on a non-recurring basis, except for definite-lived intangibles acquired and contingent consideration as a part of the acquisition of First Source Electronics, LLC discussed in Note 5, as of December 31, 2019 and December 31, 2018 . The contingent consideration is classified as Level 3 and valued based on a Monte Carlo valuation model.

Business Combinations

Business Combinations [Abstract]
Business Combinations	Business Combinations On September 17, 2019, the Company entered into and closed on an Asset Purchase Agreement (the “Agreement”) with First Source Electronics, LLC (“FSE”), Kevin Popielarczyk and Richard Vuoto (collectively, “Principals”) and the Company’s wholly-owned subsidiary, CVG FSE, LLC (“CVG FSE”). The Agreement provided for the acquisition (the "FSE Acquisition") by CVG FSE of substantially all of the assets and certain liabilities of FSE in exchange for a cash purchase price of $34.0 million , subject to a net working capital adjustment, plus a right to earn up to $10.8 million in contingent milestone payments. The purchase was funded through domestic cash on hand and $2.0 million of borrowings under our revolving credit facility. FSE is in the business of manufacturing, distributing, marketing and selling cable and electro-mechanical assemblies, control panels and other business and consumer electronics products and services. FSE improves our ability to participate in the progression of digitalization, connectivity and associated power and data applications. Furthermore, this strategic acquisition complements our high-complexity, low-to-medium volume electrical business, and provides an entry into the warehouse automation market, while also providing us with the opportunity to leverage our global footprint and to increase cross selling opportunities. The milestone payments are payable based on achieving certain earnings before interest, taxes, depreciation and amortization ("EBITDA") thresholds over the periods from (a) September 18, 2019 through September 17, 2020, (b) September 18, 2019 through March 17, 2021, (c) September 18, 2019 through September 17, 2022 and (d) March 18, 2021 through September 17, 2022. The payment amount will be determined on a sliding scale for reaching between 90% and 100% of the respective EBITDA targets. The fair value for the milestone payments is based on a Monte Carlo simulation utilizing forecasted EBITDA through September 17, 2022. The estimate was recorded within other long-term liabilities in the Consolidated Balance Sheet as of September 30, 2019. The total undiscounted milestone payments is estimated at $5.6 million and the fair value is $4.7 million as of September 30, 2019. The Agreement contains customary indemnification provisions and provided for the establishment of an escrow fund of $3.0 million of the purchase price to secure indemnification claims by CVG FSE for an 18-month period. The Company is a party to the Agreement solely as a guarantor of CVG FSE’s payment obligations. The operating results of FSE, since the date of acquisition, have been included in our consolidated financial statements. From the date of the FSE Acquisition through December 31, 2019, FSE operations recorded revenues of approximately $12.8 million resulting in net income of $0.2 million for the period within the Electrical Systems Segment. Acquisition related expenses for FSE of approximately $0.9 million were incurred for the year ended December 31, 2019 and have been recorded as selling, general and administrative expenses in our consolidated statements of operations. The FSE Acquisition was accounted for under the acquisition method of accounting. Under acquisition accounting, the acquired tangible and intangible assets and liabilities of FSE have been recorded at their respective fair values. The Company has completed its preliminary assessment of fair values of assets acquired and liabilities assumed, and the preliminary amounts are reflected in the table below. The purchase price associated with the FSE Acquisition exceeded the preliminary fair value of the net assets acquired by approximately $20.4 million . This reflects an increase of $2.7 million from the initial valuation as of September 30, 2019 . As of December 31, 2019, the net working capital adjustment is still preliminary. The excess purchase price over net assets acquired is recorded as goodwill and was determined as follows: Initial cash paid, net of working capital adjustment $ 34,000 Contingent consideration at fair value 4,700 Total consideration $ 38,700 Net assets at fair value 18,335 Excess of total consideration over net assets acquired $ 20,365 In the fourth quarter of 2019, management decreased the value of definite-lived intangible assets with an offset to goodwill to reflect a refinement of valuation assumptions. The allocation of the fair value of the assets acquired and liabilities assumed is as follows: Accounts receivable $ 6,567 Inventories 3,140 Prepaid and other current assets 353 Property, plant and equipment 503 Other long-term assets 1,650 Definite-lived intangible assets 14,500 Goodwill 20,365 Accounts payable and accrued liabilities (7,204 ) Other long-term liabilities (1,174 ) Total consideration $ 38,700 The following unaudited pro forma information for the twelve months ended December 31, 2019 and 2018 presents the result of operations as if the FSE Acquisition had taken place at the beginning of the annual reporting period. The pro forma results reflect estimates and assumptions and are not necessarily indicative of the financial position or result of operations had the acquisition taken place at the beginning of the period. The Company adjusted historical results for assumed intangible amortization expense consistent with future years and assumed an effective tax rate of 25% . In addition, the pro forma results are not necessarily indicative of the future financial or operating results. Twelve months ended December 31, (unaudited) 2019 2018 (as restated) Revenue $ 936,766 $ 935,596 Net income $ 18,324 $ 44,139 Earnings per share attributable to common stockholders: Basic $ 0.60 $ 1.46 Diluted $ 0.59 $ 1.44

Leases	Leases The Company leases office, warehouse and manufacturing space and certain equipment under non-cancelable operating lease agreements that generally require us to pay maintenance, insurance, taxes and other expenses in addition to annual rental fees.

If the agent is unable to calculate average daily availability for a fiscal quarter due to the borrowers' failure to deliver a borrowing base certificate when required, the applicable margin will be set at Level I until the first day of the calendar month following receipt of a borrowing base certificate. As of December 31, 2019 , the applicable margin was set at Level III. The unamortized deferred financing fees associated with our revolving credit facility of $0.6 million and $0.7 million as of December 31, 2019 and December 31, 2018 , respectively, are being amortized over the remaining life of the agreement. As of December 31, 2019 and December 31, 2018 , we did not have borrowings under the revolving credit facility and had outstanding letters of credit of $1.6 million and $1.7 million , respectively. We had borrowing availability of $55.1 million at December 31, 2019 . The Company pays a commitment fee to the lenders equal to 0.25% per annum of the unused amounts under the revolving credit facility. Terms, Covenants and Compliance Status The Third ARLS Agreement requires the maintenance of a minimum fixed charge coverage ratio. The borrowers are not required to comply with the fixed charge coverage ratio requirement for so long as the borrowers maintain borrowing availability under the revolving credit facility at the greater of (i) $5,000,000 or (ii) ten percent ( 10% ) of the revolving commitments. If borrowing availability falls below this threshold at any time, the borrowers would be required to comply with the fixed charge coverage ratio of 1.00 :1.00 as of the end of each relevant fiscal quarter and would be required to continue to comply with these requirements until the borrowers have borrowing availability in excess of this threshold for 60 consecutive days. Since the Company had borrowing availability in excess of this threshold from December 31, 2018 through December 31, 2019 , the Company was not required to comply with the minimum fixed charge coverage ratio covenant during the year ended December 31, 2019 . The Third ARLS Agreement contains customary restrictive covenants, including limitations on our ability and the ability of our subsidiaries to: incur additional debt; pay dividends or other restricted payments; make investments; engage in transactions with affiliates; create liens on assets; and consolidate, merge or transfer all or substantially all of our assets and the assets of our subsidiaries. The Third ARLS Agreement also contains customary reporting and other affirmative covenants. The Company was in compliance with these covenants as of December 31, 2019 . Voluntary prepayments of amounts outstanding under the Revolving Credit Facility are permitted at any time, without premium or penalty, other than (to the extent applicable) customary LIBOR breakage charges. The Third ARLS Agreement requires the borrowers to make mandatory prepayments upon the receipt of insurance or condemnation proceeds in respect of the revolving credit facility’s priority collateral. The Third ARLS Agreement includes customary events of default (subject in certain cases to customary grace and cure periods) which include, among others: • nonpayment of obligations when due; • breach of covenants or other agreements in the Third ARLS Agreement; • a change of control; and • defaults in payment of certain other indebtedness, including the term loan credit facility." id="sjs-B4">Debt Debt consisted of the following at December 31 : 2019 2018 Term loan and security agreement 1, 2 $ 156,384 $ 163,758 1 Presented in the Consolidated Balance Sheets as current portion of long-term debt of $3.3 million , net of current prepaid debt financing costs of $0.5 million and current original issue discount of $0.6 million ; and long-term debt of $153.1 million , net of long-term prepaid debt financing costs of $1.2 million and long-term original issue discount of $1.3 million as of December 31, 2019 . 2 Presented in the Consolidated Balance Sheets as current portion of long-term debt of $9.1 million , net of current prepaid debt financing costs of $0.6 million , and current original issue discount of $0.6 million ; and long-term debt of $154.7 million , net of long-term prepaid debt financing costs of $1.7 million and long-term original issue discount of $1.8 million as of December 31, 2018 . Term Loan and Security Agreement On April 12, 2017, the Company entered into a $175.0 million senior secured term loan credit facility (the “Term Loan Facility”), maturing on April 12, 2023, pursuant to a term loan and security agreement (the “TLS Agreement”) with the Company and certain subsidiaries of the Company party thereto as guarantors, Bank of America, N.A., as administrative agent, and other lender parties thereto. Concurrent with the closing of the TLS Agreement, the proceeds of the Term Loan Facility were used, together with cash on hand in the amount of $74.0 million , to (a) fund the redemption, satisfaction and discharge of all of the Company’s outstanding 7.875% notes along with accrued interest; and (b) pay related transaction costs, fees and expenses. In conjunction with the redemption of the 7.875% notes, the Company recognized a non-cash charge of $1.6 million in the second quarter of 2017 to write-off deferred financing fees and a charge for interest of $1.5 million paid to bondholders during the 30-day notification period associated with the redemption of the 7.875% notes. The interest on the Term Loan Facility is variable and is comprised of 1) an applicable margin of either (i) 5.00% for base rate loans or (ii) 6.00% for LIBOR loans, and 2) an applicable rate of either (i) base rate for any day, a per annum rate equal to the greater of (a) the prime rate for such day, (b) the federal funds rate for such day, plus 0.50% , or (c) LIBOR for a 30 day interest period as of such day, plus 1.00% , or (ii) LIBOR as quoted two business days prior to the commencement of an interest period provided that LIBOR at no time falls below 1.00% . There was $0.1 million in accrued interest as of December 31, 2019 . The unamortized deferred financing fees of $1.7 million and original issue discount of $1.8 million are netted against the aggregate book value of the outstanding debt to arrive at a balance of $156.4 million as of December 31, 2019 and are being amortized over the remaining life of the agreement. The weighted average interest rate was 8.29% as of December 31, 2019 and 8.09% as of December 31, 2018 . The Term Loan Facility is a senior secured obligation of the Company. Our obligations under the TLS Agreement are guaranteed by the Company and certain subsidiaries of the Company. The obligations of the Company and the guarantors under the TLS Agreement are secured (subject to certain permitted liens) by a first-priority lien on substantially all of the non-current assets (and a second priority lien on substantially all of the current assets) of the Company and the guarantors, including a first priority pledge of certain capital stock of the domestic and foreign subsidiaries directly owned by the Company and the guarantors. The liens, the security interests and all of the obligations of the Company and the guarantors and all provisions regarding remedies in an event of default are subject to an intercreditor agreement among the Company, the guarantors, the agent for the lenders party to the Company’s revolving credit facility and the collateral agent under the TLS Agreement. Terms, Covenants and Compliance Status The TLS Agreement contains customary restrictive covenants, including limitations on our ability and the ability of our subsidiaries to: incur additional debt; pay dividends or other restricted payments; make investments; engage in transactions with affiliates; create liens on assets; and consolidate, merge or transfer all or substantially all of our assets and the assets of our subsidiaries. In addition, the TLS Agreement contains a financial maintenance covenant requiring the Company to maintain a total leverage ratio as of the last day of any fiscal quarter not to exceed the ratios set forth in the applicable table within the TLS Agreement. The TLS Agreement also contains customary reporting and other affirmative covenants. We were in compliance with the covenants as of December 31, 2019 . The TLS Agreement requires the Company to repay principal of approximately $1.1 million on the last day of each quarter commencing with the quarter ending September 30, 2017 with the remaining outstanding principal due at maturity on April 12, 2023. Voluntary prepayments of amounts outstanding under the TLS Agreement are permitted at any time, without premium or penalty. In addition, to the extent applicable, customary LIBOR breakage charges may be payable in connection with any prepayment. The TLS Agreement requires the Company to make mandatory prepayments with excess cash flow, the proceeds of certain asset dispositions and upon the receipt of insurance or condemnation proceeds; and in the case of an asset disposition or insurance or condemnation event, to the extent the Company does not reinvest the proceeds within the periods set forth in the TLS Agreement. A mandatory prepayment of $4.2 million pursuant to the TLS Agreement was made during the first quarter of 2019 as a result of our 2018 Excess Cash Flow Period. The TLS Agreement includes customary events of default (subject in certain cases to customary grace and cure periods) which include, among others: • nonpayment of obligations when due; • breach of covenants or other agreements in the TLS Agreement; and • defaults in payment of certain other indebtedness. Revolving Credit Facility On April 12, 2017, Commercial Vehicle Group Inc. and certain subsidiaries, collectively the "borrowers", entered into the Third Amended and Restated Loan and Security Agreement (the "Third ARLS Agreement") increasing its senior secured revolving credit facility (the "Revolving Credit Facility") to $65 million from $40 million and setting the maturity date to April 12, 2022. Up to an aggregate of $10.0 million is available to the borrowers for the issuance of letters of credit, which reduces availability under the Third ARLS Agreement. The Third ARLS Agreement included amendments to certain definitions and covenants including, but not limited to, amendments to (i) permitted debt, (ii) permitted distributions, (iii) distribution of assets, and (iv) the calculation of EBITDA. The Third ARLS Agreement contains a fixed charge coverage ratio maintenance covenant of 1.00 :1.00 and amended the availability threshold for triggering compliance with the fixed charge coverage ratio. The borrowers’ obligations under the Revolving Credit Facility are secured (subject to certain permitted liens) by a first-priority lien on substantially all of the current assets (and a second priority lien on substantially all of the non-current assets) of the borrowers. Each of the Company and each other borrower is jointly and severally liable for the obligations under the Revolving Credit Facility and unconditionally guarantees the prompt payment and performance thereof. The liens, the security interests and all of the obligations of the Company and each other borrower and all provisions regarding remedies in an event of default are subject to an intercreditor agreement among the Company, certain of its subsidiaries, the agent under the Third ARLS Agreement and the collateral agent for the lenders party to the Company’s Term Loan credit Facility. On September 18, 2019, the Company and certain of its subsidiaries, as co-borrowers, entered into an Amendment No. 1 (the “Amendment”), which amends the Third ARLS Agreement. The Amendment amends the terms of the Revolving Credit Facility to entitle the Company and the other named borrowers thereunder (subject to the terms and conditions described therein) to request loans and other financial accommodations in an amount equal to the lesser of $90.0 million and a borrowing base composed of accounts receivable and inventory (such facility, the “Tranche A Facility”). Of the $90.0 million , $7.0 million shall be available as a first-in, last-out facility (“Tranche B Facility”) at a 100 basis points premium, as detailed in the below applicable margin table. The Company can increase the size of the revolving commitments under the Revolving Credit Facility by an incremental $20.0 million , subject to the consent of the lenders providing the incremental commitments. The applicable margin is based on average daily availability under the revolving credit facility as follows: Level Average Daily Availability Tranche A Tranche A Tranche B Tranche B III ≥ $30,000,000 0.50% 1.50% 1.50% 2.50% II > $15,000,000 but < $30,000,000 0.75% 1.75% 1.75% 2.75% I ≤ $15,000,000 1.00% 2.00% 2.00% 3.00% The applicable margin is subject to increase or decrease by the agent on the first day of the calendar month following each fiscal quarter end. If the agent is unable to calculate average daily availability for a fiscal quarter due to the borrowers' failure to deliver a borrowing base certificate when required, the applicable margin will be set at Level I until the first day of the calendar month following receipt of a borrowing base certificate. As of December 31, 2019 , the applicable margin was set at Level III. The unamortized deferred financing fees associated with our revolving credit facility of $0.6 million and $0.7 million as of December 31, 2019 and December 31, 2018 , respectively, are being amortized over the remaining life of the agreement. As of December 31, 2019 and December 31, 2018 , we did not have borrowings under the revolving credit facility and had outstanding letters of credit of $1.6 million and $1.7 million , respectively. We had borrowing availability of $55.1 million at December 31, 2019 .

See Note 2 for details. We assess whether valuation allowances should be established against deferred tax assets based on consideration of all available evidence using a “more likely than not” standard. This assessment considers, among other matters, the nature, frequency and severity of recent losses, forecasts of future profitability, the duration of statutory carryforward periods, our experience with unused tax attributes expiring and tax planning alternatives. In making such judgments, significant weight is given to evidence that can be objectively verified. During 2019, we recorded additional valuation allowance of $0.7 million on the deferred tax assets of our United Kingdom subsidiary and certain U.S. state tax net operating loss carryforwards, and released $3.4 million in valuation allowances related to the deferred tax assets of our Luxembourg subsidiaries. We expect to be able to realize the benefits of all of our deferred tax assets that are not currently offset by a valuation allowance, as discussed above. In the event that our actual results differ from our estimates or we adjust these estimates in future periods, the effects of these adjustments could materially impact our financial position and results of operations. As of December 31, 2019 , the Company had net operating loss carryforwards of $115.2 million , of which $55.2 million related to foreign jurisdictions and $60.0 million related to U.S. state jurisdictions. The carryforward periods for these net operating losses range from five years to indefinite. Utilization of these losses is subject to the tax laws of the applicable tax jurisdiction and may be limited by the ability of certain subsidiaries to generate taxable income in the associated tax jurisdiction. We have established valuation allowances for all net operating losses that we believe are more likely than not to expire before they can be utilized. As of December 31, 2019 , we had $2.5 million of U.S. foreign tax credits carried forward primarily attributable to the deemed repatriation of the accumulated untaxed earnings of our foreign subsidiaries resulting from the U.S. Tax Reform. Utilization of these credits may be limited if the Company does not continue to generate U.S. federal taxable income in future years. The credits begin to expire in 2027. As of December 31, 2019 , we had $1.3 million of research and development tax credits being carried forward related to our U.S. operations. Utilization of these credits may be limited if the Company does not continue to generate U.S. federal taxable income in future years. As a result of the Tax Cuts and Jobs Act of 2017, the unutilized research and development tax credits the Company generated after December 31, 2017 can be carried forward indefinitely whereas the credits generated prior to that date are subject to a 20-year carryforward period. Approximately $0.5 million of the Company's tax credits are subject to the 20-year carryforward period and begin to expire between between 2025 and 2039 . As of December 31, 2019 , cash of $39.5 million was held by foreign subsidiaries. During the year ended December 31, 2019 , $19.4 million , net of $1.0 million in foreign withholding tax incurred, was repatriated from the Company's foreign subsidiaries. The Company plans to repatriate an additional $12.0 million in 2020 and a $0.8 million deferred tax liability was recorded during the year ended December 31, 2019 for the expected future income tax implications. We file federal income tax returns in the U.S. and income tax returns in various states and foreign jurisdictions. In the U.S., we are generally no longer subject to tax assessment for tax years prior to 2016. In our major non-U.S. jurisdictions including China, Czech Republic, Mexico and the United Kingdom, tax years are typically subject to examination for three to five years. As of December 31, 2019 , and 2018, we provided a liability of $0.9 million for unrecognized tax benefits related to U.S. federal and state, and foreign jurisdictions. The majority of these unrecognized tax benefits are netted against their related noncurrent deferred tax assets. We accrue interest and penalties related to unrecognized tax benefits through income tax expense. We had $0.4 million and $0.3 million accrued for the payment of interest and penalties as of December 31, 2019 and December 31, 2018, respectively. Accrued interest and penalties are included in the $0.9 million of unrecognized tax benefits. A reconciliation of the beginning and ending amount of unrecognized tax benefits (including interest and penalties) at December 31 follows: 2019 2018 (as restated) 2017 Balance - Beginning of the year 1 $ 894 $ 811 $ 1,098 Gross increase - tax positions in prior periods 1 70 66 70 Gross decreases - tax positions in prior periods 1 (39 ) (14 ) (219 ) Gross increases - current period tax positions 1 — 59 65 Lapse of statute of limitations (12 ) (12 ) (221 ) Currency translation adjustment (5 ) (16 ) 18 Balance - End of the year 1 $ 908 $ 894 $ 811 (1) The Company has adjusted certain prior period amounts for the restatement and immaterial corrections of error.

Segment Reporting [Abstract]
Segment Reporting and Geographic Locations	Segment Reporting and Geographic Locations In the year ended December 31, 2018 , we completed a strategic reorganization of our operations into two business segments, Electrical Systems and Global Seating. As a result of the strategic reorganization, we restated prior period segment information to conform to the current period segment presentation. Operating segments are defined as components of an enterprise that are evaluated regularly by the Company’s CODM, which is our President and Chief Executive Officer. Each of these segments consists of a number of manufacturing facilities. Certain of our facilities manufacture and sell products through both of our segments. Each manufacturing facility that sells products through both segments is reflected in the financial results of the segment that has the greatest amount of sales from that manufacturing facility. Our segments are more specifically described below. The Electrical Systems Segment manufactures and sells the following products: • Electrical wire harnesses, control panels, electro-mechanical and cable assemblies primarily for the construction, agricultural, industrial, automotive, truck, mining, rail and military industries in North America, Europe and Asia-Pacific; • Trim systems and components ("Trim") primarily for the North America MD/HD Truck market; • Mirrors, wipers and controls primarily for the truck, bus, agriculture, construction, rail and military markets in North America and Europe; • Cab structures for the North American MD/HD Truck market; and • Aftermarket components in North America. The Global Seating Segment manufactures and sells the following products: • Seats and seating systems ("Seats") primarily to the MD/HD Truck, construction, agriculture and mining markets in North America, Asia-Pacific and Europe; • Office seating in Europe and Asia-Pacific; and • Aftermarket seats and components in North America, Europe and Asia-Pacific. Corporate expenses consist of overhead and shared costs that are not directly attributable to the operations of a segment. For purposes of business segment performance measurement, some of these costs are for the benefit of the operations and are allocated based on a combination of methodologies. The costs that are not allocated to a segment are considered stewardship costs and remain at corporate in our segment reporting. The following table presents segment revenues, gross profit, selling, general and administrative expenses, amortization expense, operating income, capital expenditures, depreciation expense and other items for the year ended December 31, 2019 . The table does not include assets as the CODM does not review assets by segment.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Leases - As disclosed in Note 6, we lease office, warehouse and manufacturing space and equipment under non-cancelable operating lease agreements that generally require us to pay maintenance, insurance, taxes and other expenses in addition to annual rental fees. As of December 31, 2019 , our equipment leases did not provide for any material guarantee of a specified portion of residual values. Guarantees - Costs associated with guarantees are accrued when it is probable that a liability has been incurred and the amount can be reasonably estimated. The most likely cost to be incurred is accrued based on an evaluation of available facts; where no amount within a range of estimates is more likely, the minimum is accrued. As of December 31, 2019 and 2018 , we had no such guarantees. Litigation - We are subject to various legal proceedings and claims arising in the ordinary course of business, including but not limited to workers' compensation claims, OSHA investigations, employment disputes, unfair labor practice charges, customer and supplier disputes, service provider disputes, product liability claims, intellectual property disputes, environmental claims arising out of the conduct of our businesses and examinations by the Internal Revenue Service. Management believes that the Company maintains adequate insurance and that we have established reserves for issues that are probable and estimable in amounts that are adequate to cover reasonable adverse judgments not covered by insurance. Based upon the information available to management and discussions with legal counsel, it is the opinion of management that the ultimate outcome of the various legal actions and claims that are incidental to our business are not expected to have a material adverse impact on the consolidated financial position, results of operations, equity or cash flows; however, such matters are subject to many uncertainties and the outcomes of individual matters are not predictable with any degree of assurance. Warranty - We are subject to warranty claims for products that fail to perform as expected due to design or manufacturing deficiencies. Depending on the terms under which we supply products to our customers, a customer may hold us responsible for some or all of the repair or replacement costs of defective products when the product supplied did not perform as represented. Our policy is to record provisions for estimated future customer warranty costs based on historical trends and for specific claims. These amounts, as they relate to the years ended December 31, 2019 and 2018 , are included within accrued liabilities and other in the accompanying Consolidated Balance Sheets. The following presents a summary of the warranty provision for the years ended December 31 : 2019 2018 Balance - Beginning of the year $ 3,911 $ 3,490 Provision for new warranty claims 1,895 2,435 Change in provision for preexisting warranty claims (27 ) 932 Deduction for payments made (2,705 ) (2,803 ) Currency translation adjustment 8 (143 ) Balance - End of year $ 3,082 $ 3,911 Debt Payments - As disclosed in Note 9, the TLS Agreement requires the Company to repay a fixed amount of principal on a quarterly basis, make mandatory prepayments of excess cash flows and make voluntary prepayments that coincide with certain events. The following table provides future minimum principal payments and mandatory prepayment of excess cash flows due on long-term debt for the next five years. The existing long-term debt agreement matures in 2023; no payments are due thereafter: Year Ending December 31, 2020 $ 4,375 2021 4,375 2022 4,375 2023 146,788 2024 — Thereafter —

Preferred Stock - Our authorized capital stock includes preferred stock of 5,000,000 shares with a par value of $0.01 per share, with no shares outstanding as of December 31, 2019 and 2018 . Earnings (Loss) Per Share - Basic earnings (loss) per share is determined by dividing net income by the weighted average number of common shares outstanding during the year. Diluted earnings (loss) per share presented is determined by dividing net income by the weighted average number of common shares and potential common shares outstanding during the period as determined by the treasury stock method. Potential common shares are included in the diluted earnings per share calculation when dilutive. Diluted earnings (loss) per share for years ended December 31, 2019 , 2018 and 2017 includes the effects of potential common shares when dilutive. Net income has been restated in 2018 and corrected for immaterial errors in 2017, along with its impact to Basic and Dilutive EPS as discussed in Note 2, and is as follows: 2019 2018 (as restated) 2017 Net income (loss) attributable to common stockholders $ 15,778 $ 41,489 $ (2,269 ) Weighted average number of common shares outstanding 30,602 30,277 29,942 Dilutive effect of restricted stock grants after application of the treasury stock method 221 310 — Dilutive shares outstanding 30,823 30,587 29,942 Basic earnings (loss) per share attributable to common stockholders $ 0.52 $ 1.37 $ (0.08 ) Diluted earnings (loss) per share attributable to common stockholders $ 0.51 $ 1.36 $ (0.08 ) The Company has adjusted certain prior period amounts for the restatement and immaterial corrections of error. See Note 2 for details. There were no anti-dilutive shares for the year ended December 31, 2019 . For the year ended December 31, 2018 , diluted earnings (loss) per share excludes 55 thousand shares, of nonvested restricted stock as the effect would have been anti-dilutive.

Performance Awards

Performance Awards	12 Months Ended

Share-based Payment Arrangement [Abstract]
Performance Awards	Performance Awards Awards, defined as cash, shares or other awards, may be granted to employees under the Commercial Vehicle Group, Inc. 2014 Equity Incentive Plan (the “2014 EIP”). The cash award is earned and payable based upon the Company’s relative total shareholder return in terms of ranking as compared to the peer group over a three -year period (the “Performance Period”). Total shareholder return is determined by the percentage change in value (positive or negative) over the applicable measurement period as measured by dividing (A) the sum of the cumulative value of dividends and other distributions paid on the Common Stock for the applicable measurement period and the difference (positive or negative) between each such company’s starting stock price and ending stock price, by (B) the starting stock price. The award is payable at the end of the Performance Period in cash if the employee is employed through the end of the Performance Period. If the employee is not employed during the entire Performance Period, the award is forfeited. These grants are accounted for as cash settlement awards for which the fair value of the award fluctuates based on the change in total shareholder return in relation to the peer group. The following table summarizes performance awards granted in the form of cash awards under the 2014 EIP in November 2018 , 2017 and 2016: Grant Date Grant Amount Adjustments Forfeitures Payments Adjusted Award Value at December 31, 2019 Vesting Schedule Remaining Periods (in Months) to Vesting November 2016 $ 1,434 — $ (88 ) $ (1,346 ) $ — November 2019 0 November 2017 1,584 (16 ) (195 ) $ — 1,373 November 2020 9 November 2018 1,590 (37 ) (200 ) — 1,353 November 2021 21 $ 4,608 $ (53 ) $ (483 ) $ (1,346 ) $ 2,726 The Company generally grants performance awards in November of each year. However, there were no performance awards granted in November 2019. The next cash award under the 2014 EIP will be granted in the three months ended March 31, 2020. Unrecognized compensation expense was $1.1 million and $2.6 million as of December 31, 2019 and 2018 , respectively.

Share-based Payment Arrangement [Abstract]
Share-Based Compensation	Share-Based Compensation The compensation expense for our share-based compensation arrangements (see Restricted Stock Awards below) was $2.8 million , $3.1 million and $2.5 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. Share-based compensation expense is included in selling, general and administrative expenses in the Consolidated Statements of Operations. Restricted Stock Awards - Restricted stock is a grant of shares of common stock that may not be sold, encumbered or disposed of and that may be forfeited in the event of certain terminations of employment or in the case of the board of directors, a separation for cause, prior to the end of a restricted period set by the compensation committee of the board of directors. Forfeitures are recorded as they occur. A participant granted restricted stock generally has all of the rights of a stockholder, unless the compensation committee determines otherwise. The following table summarizes information about unvested restricted stock grants as of December 31, 2019 (in thousands): Grant Shares Granted Unvested Shares Vesting Schedule Unearned Remaining October 2017 303 90 3 equal annual installments commencing on October 20, 2018 $ 711.7 10 October 2018 382 242 3 equal annual installments commencing on October 20, 2019 $ 1,500.7 22 May 2019 71 59 Shares granted to independent board members that fully vest as of May 16, 2020 $ 150.0 4 October 2019 12 12 3 equal annual installments commencing on October 20, 2020 $ 77.5 33 As of December 31, 2019 , there was approximately $2.4 million of unrecognized compensation expense related to non-vested share-based compensation arrangements granted under our equity incentive plans. This expense is subject to future adjustments and forfeitures and will be recognized on a straight-line basis over the remaining period listed above for each grant. A summary of the status of our restricted stock awards as of December 31, 2019 and changes during the twelve-month period ending December 31, 2019 , 2018 and 2017 is presented below: 2019 2018 2017 Shares Weighted- Shares Weighted- Shares Weighted- Nonvested - beginning of year 760 $ 7.56 787 $ 6.84 981 $ 4.70 Granted 87 $ 7.57 446 $ 7.20 354 $ 9.77 Vested (418 ) $ 7.41 (452 ) $ 5.97 (509 ) $ 4.90 Forfeited (26 ) $ 7.52 (21 ) $ 7.31 (39 ) $ 4.84 Nonvested - end of year 403 $ 7.72 760 $ 7.56 787 $ 6.84 As of December 31, 2019 , a total of 2.1 million shares were available for future grants from the shares authorized for award under our 2014 Equity Incentive Plan, including cumulative forfeitures. Repurchase of Common Stock - We did not repurchase any of our common stock on the open market as part of a stock repurchase program during 2019 ; however, our employees surrendered 130 thousand shares of our common stock to satisfy tax withholding obligations on the vesting of the restricted stock awards.

Retirement Benefits [Abstract]
Defined Contribution Plans, Pension and Other Post-Retirement Benefit Plans	Defined Contribution Plan, Pension and Other Post-Retirement Benefit Plans Defined Contribution Plan - We sponsor a defined contribution plan covering eligible employees. Eligible employees can contribute on a pre-tax basis to the plan. In accordance with the terms of the 401(k) plan, we elect to match a certain percentage of the participants’ contributions to the plan, as defined. We recognized expense associated with the plan of $4.6 million in 2019 , $3.6 million in 2018 and $3.0 million in 2017 . Pension and Other Post-Retirement Benefit Plans - We sponsor pension and other post-retirement benefit plans that cover certain hourly and salaried employees in the U.S. and United Kingdom. Each of the plans are frozen to new participants and to additional service credits earned. In December 2018, we consolidated the U.S. plans. Our policy is to make annual contributions to the plans to fund the minimum contributions, as required by local regulations. During the three months ended March 31, 2019, the Company offered employees with deferred vested balances in the U.S. defined benefit pension plan the opportunity to voluntarily elect an early payout of their benefits. Payouts totaling $7.9 million were made during 2019 and were paid out of plan assets resulting in a non-cash settlement charge of $2.5 million , which was recorded in interest and other expense in the Condensed Consolidated Statements of Operations and is reflected in amortization of prior service cost in the net periodic (benefit) cost table below. The change in benefit obligation, plan assets and funded status as of December 31 is as follows: U.S. Pension and Other Post-Retirement Benefit Plans Non-U.S. Pension Plan 2019 2018 2019 2018 Change in benefit obligation: Benefit obligation — Beginning of the year $ 45,238 $ 50,072 $ 40,265 $ 45,737 Service cost — — — 788 Interest cost 1,483 1,664 1,112 1,030 Participant contributions 6 9 — — Benefits paid (10,346 ) (2,360 ) (1,681 ) (1,816 ) Actuarial (gain) loss 3,196 (4,147 ) 3,730 (2,772 ) Exchange rate changes — — 1,415 (2,702 ) Benefit obligation at end of the year 39,577 45,238 44,841 40,265 Change in plan assets: Fair value of plan assets — Beginning of the year 42,962 45,046 30,424 35,377 Actual return on plan assets 6,588 (2,259 ) 3,610 (1,808 ) Employer contributions 835 2,526 887 763 Participant contributions 6 9 — — Benefits paid (10,346 ) (2,360 ) (1,681 ) (1,816 ) Exchange rate changes — — 1,081 (2,092 ) Fair value of plan assets at end of the year 40,045 42,962 34,321 30,424 Funded status $ 468 $ (2,276 ) $ (10,520 ) $ (9,841 ) Significant Obligation Loss - The projected U.S. benefit obligation includes a net loss of $3.2 million for the year ended December 31, 2019 . The loss is a result of changes in key actuarial assumptions, including the early payout of benefits decrease in the discount rate. The projected Non-U.S. benefit obligation includes a net loss of $3.7 million for the year ended December 31, 2019 driven primarily by a decrease in the discount rate assumption. As a result of pension legislation in the United Kingdom that was effective October 2018, the Company was required to amend its pension plan to equalize benefits between male and female pensioners. This resulted in additional pension obligation and a reduction to accumulated other comprehensive income of $0.8 million in 2018. There are no material updates to this estimate for as of December 31, 2019. Amounts recognized in the Consolidated Balance Sheets at December 31 consisted of: U.S. Pension and Other Post-Retirement Benefit Plans Non-U.S. Pension Plan 2019 2018 2019 2018 Noncurrent assets $ 633 $ — $ — $ — Current liabilities (19 ) (28 ) — — Noncurrent liabilities (146 ) (2,248 ) (10,520 ) (9,841 ) Amount recognized $ 468 $ (2,276 ) $ (10,520 ) $ (9,841 ) The components of net periodic (benefit) cost for the years ended December 31 were as follows: U.S. Pension and Other Post-Retirement Benefit Plans Non-U.S. Pension Plan 2019 2018 2017 2019 2018 2017 Service cost $ — $ — $ 116 $ — $ — $ — Interest cost 1,483 1,664 1,810 1,112 1,030 1,138 Expected return on plan assets (2,393 ) (3,151 ) (2,684 ) (1,117 ) (1,210 ) (1,196 ) Amortization of prior service cost 1 2,528 6 6 47 — — Recognized actuarial loss 308 263 21 531 496 312 Net periodic cost (benefit) $ 1,926 $ (1,218 ) $ (731 ) $ 573 $ 316 $ 254 1 Includes $2.5 million non-cash settlement charge arising from the early payout of the U.S. defined benefit plan benefits. Net periodic (benefit) cost components, not inclusive of service costs, are recognized in Other Income within the Consolidated Statements of Operations. Amounts Recognized in Accumulated Other Comprehensive Income (Loss) - Amounts recognized in accumulated other comprehensive income (loss), before taking into account income tax effects, at December 31 are as follows: U.S. Pension and Other Post-Retirement Benefit Plans Non-U.S. Pension Plan 2019 2018 2017 2019 2018 2017 Net actuarial loss $ 10,937 $ 14,767 $ 13,765 $ 13,783 $ 12,972 $ 13,454 Prior service cost 45 51 57 747 788 — $ 10,982 $ 14,818 $ 13,822 $ 14,530 $ 13,760 $ 13,454 Other Changes in Plan Assets and Benefit Obligations Recognized in Other Comprehensive Income (Loss) — Amounts recognized as other changes in plan assets and benefit obligations in other comprehensive income (loss), before taking into account income tax effects, for the year ended December 31 are as follows: U.S. Pension and Other Post-Retirement Plans Non-U.S. Pension Plan 2019 2018 2019 2018 Actuarial (gain) loss $ (1,001 ) $ 1,266 $ 968 $ 245 Amortization of actuarial (loss) gain (2,829 ) (263 ) (37 ) 781 Prior service credit (6 ) (6 ) (416 ) (491 ) Total recognized in other comprehensive income (loss) $ (3,836 ) $ 997 $ 515 $ 535 Weighted-average assumptions used to determine benefit obligations at December 31 were as follows: U.S. Pension and Other Post-Retirement Benefit Plans Non-U.S. Pension 2019 2018 2019 2018 Discount rate 2.93 % 4.06 % 1.95 % 2.80 % Weighted-average assumptions used to determine net periodic benefit cost at December 31 were as follows: U.S. Pension and Other Post-Retirement Plans Non-U.S. Pension Plan 2019 2018 2017 2019 2018 2017 Discount rate 3.40 % 3.42 % 3.87 % 2.80 % 2.45 % 2.70 % Expected return on plan assets 5.34 % 7.00 % 7.00 % 3.70 % 3.70 % 3.70 % The rate of return assumptions are based on projected long-term market returns for the various asset classes in which the plans are invested, weighted by the target asset allocations. An incremental amount for active plan asset management and diversification, where appropriate, is included in the rate of return assumption. Our pension plan investment strategy is reviewed periodically, but no less frequently than annually. We employ a total return investment approach whereby a mix of equities, fixed income and real estate investments are intended to maximize the long-term return of plan assets taking into consideration a prudent level of risk. The intent of this strategy is to minimize plan expenses by outperforming plan liabilities over the long run. Risk tolerance is established through consideration of plan liabilities, plan funded status and corporate financial condition. The investment portfolio contains a diversified blend of equity, balanced, fixed income and real estate investments. Furthermore, equity investments are diversified across U.S. and non-U.S. stocks, as well as growth, value and large and small capitalizations. Other assets, such as real estate, are used judiciously to perhaps enhance long-term returns and to improve portfolio diversification. Derivatives may be used to gain market exposure in an efficient and timely manner; however, derivatives may not be used to leverage the portfolio beyond the market value of the underlying investments. Investment risk is measured and monitored on an ongoing basis in light of annual liability measurements, periodic asset/liability studies and quarterly investment portfolio reviews. We expect to contribute approximately $1.0 million to our pension plans and our other post-retirement benefit plans in 2020 . Our current investment allocation target for our pension plans for 2019 and our weighted-average asset allocations of our pension assets for the years ended December 31 , by asset category, are as follows: Target Allocation Actual Allocations as of December 31, 2019 2018 U.S. Pension Plan Non-U.S. Pension Plan U.S. Non-U.S. U.S. Non-U.S. 2019 2018 2019 2018 Cash and cash equivalents — — — — — 1 1 1 Equity/Balanced securities 27 55 55 55 28 52 53 59 Fixed income securities 63 45 25 45 62 22 46 40 Real estate 10 — 20 — 10 25 — — 100% 100% 100% 100% 100% 100% 100% 100% Our plan assets can be described as follows: Equity Securities - Includes common stocks issued by U.S., United Kingdom and other international companies, equity funds that invest in common stocks and unit linked insurance policies. Equity investments generally allow near-term (within 90 days of the measurement date) liquidity and are held in issues that are actively traded to facilitate transactions at minimum cost. Balanced Securities - Includes funds primarily invested in a mix of equity and fixed income securities where the allocations are at the discretion of the investment manager. Investments generally allow near-term (within 90 days of the measurement date) liquidity and are held in issues that are actively traded to facilitate transactions at minimum cost. Fixed Income Securities - Includes U.S. dollar-denominated and United Kingdom and other international marketable bonds and convertible debt securities as well as fixed income funds that invest in these instruments. Investments generally allow near-term liquidity and are held in issues that are actively traded to facilitate transactions at minimum cost. The fair value of fixed income securities is determined by either direct or indirect quoted market prices. When the value of assets held in separate accounts is not published, the value is based on the underlying holdings, which are primarily direct quoted market prices on regulated financial exchanges. Real Estate - Real estate provides an indirect investment into a diversified and multi-sector portfolio of property assets. The fair value of real estate investments is determined by the fund managers. The fund managers value the real estate investments via independent third-party appraisals on a periodic basis. Assumptions used to revalue the properties are updated every quarter. The fair values of our pension plan assets by asset category and by level as described in Note 4 for the years ended December 31, 2019 and 2018 are as follows: December 31, 2019 Quoted Prices in Significant Significant Total Level 1 Level 2 Level 3 Cash and cash equivalents $ 332 $ 332 $ — $ — Equities: U.S. large value 2,434 2,434 — — U.S. large growth 2,059 2,059 — — International blend 4,854 — 4,854 — Emerging markets 1,603 1,603 — — Balanced 18,246 — 18,246 — Fixed income securities: Government bonds 24,917 — 24,917 — Corporate bonds 12,634 — 12,634 — Other 3,217 — 3,217 — Real Estate: U.S. property 4,070 — — 4,070 Total pension fund assets $ 74,366 $ 6,428 $ 63,868 $ 4,070 December 31, 2018 Quoted Prices in Significant Significant Total Level 1 Level 2 Level 3 Cash and cash equivalents $ 623 $ 623 $ — $ — Equities: U.S. large value 4,815 4,815 — — U.S. large growth 5,270 5,270 — — International blend 9,134 — 9,134 — Emerging markets 3,093 3,093 — — Balanced 17,952 — 17,952 — Fixed income securities: Government bonds 10,240 — 10,240 — Corporate bonds 11,297 — 11,297 — Real Estate: U.S. property 10,962 — — 10,962 Total pension fund assets $ 73,386 $ 13,801 $ 48,623 $ 10,962 The fair value of our pension plan assets measured using significant unobservable inputs (Level 3) at December 31 are as follows: 2019 2018 Beginning balance $ 10,962 $ 10,153 Actual return on assets held at reporting date 430 809 Purchases, sales and settlements, net (7,322 ) — Ending balance $ 4,070 $ 10,962 The following table summarizes our expected future benefit payments of our pension and other post-retirement benefit plans: Year Ending December 31, Pension Plans 2020 $ 4,390 2021 $ 4,396 2022 $ 4,360 2023 $ 4,453 2024 $ 4,493 2025 to 2029 $ 22,209

Restructuring and Related Activities [Abstract]
Cost Reduction and Manufacturing Capacity Rationalization	Cost Reduction and Manufacturing Capacity Rationalization During 2019, the Company began implementing cost reduction and manufacturing capacity rationalization initiatives (the "Restructuring Initiatives") in response to declines in end market volumes. These actions were initiated in 2019 and are expected to continue through 2020. The Restructuring Initiatives consist primarily of headcount reductions in each segment and at corporate, as well as other costs associated with transfer of production and subsequent closure of facilities. Total pre-tax costs associated with these actions are estimated to be $5 million to $7 million and are expected to lower operating costs beginning in the first quarter of 2020. A summary of the costs incurred in the year ended December 31, 2019 follows: 2019 Employee Costs Facility Exit and Other Costs Total Electrical Systems $ 1,820 $ 339 $ 2,159 Global Seating 489 — 489 Corporate 310 — 310 Total $ 2,619 $ 339 $ 2,958 Of the $3.0 million incurred in the year ended December 31, 2019, $2.2 million was recorded in cost of revenues and $0.8 million was recorded in selling, general and administrative expenses.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Principles of Consolidation	The accompanying consolidated financial statements include the accounts of our wholly-owned or controlled subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include allowance for doubtful accounts, inventory reserves, goodwill, intangible and long-lived assets, pension and other post-retirement benefits, product warranty reserves, litigation reserves, and income tax valuation allowances. Actual results may differ materially from those estimates.
Cash	Cash consists of deposits with high credit-quality financial institutions.
Accounts Receivable	Trade accounts receivable are stated at current value less allowances, which approximates fair value. We review our receivables on an ongoing basis to ensure that they are properly valued and collectible. The allowance for doubtful accounts is used to record the estimated risk of loss related to our customers’ inability to pay. This allowance is maintained at a level that we consider appropriate based on factors that affect collectability, such as the financial health of our customers, historical trends of charge-offs and recoveries and current economic market conditions. As we monitor our receivables, we identify customers that may have payment problems and adjust the allowance accordingly, with the offset to selling, general and administrative expense. Account balances are charged off against the allowance when recovery is considered remote.
Inventories
Property, Plant and Equipment	Property, plant and equipment are stated at cost, net of accumulated depreciation. For financial reporting purposes, depreciation is computed using the straight-line method over the following estimated useful lives: Buildings and improvements 15 to 40 years Machinery and equipment 3 to 20 years Tools and dies 3 to 7 years Computer hardware and software 3 to 5 years Expenditures for maintenance and repairs are charged to expense as incurred. Expenditures for major betterments and renewals that extend the useful lives of property, plant and equipment are capitalized and depreciated over the remaining useful lives of the asset. When assets are retired or sold, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized in the results of operations. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the improvements or the term of the lease, whichever is shorter. Accelerated depreciation methods are used for tax reporting purposes. Depreciation expense for property, plant and equipment for each of the years ended December 31, 2019 , 2018 and 2017 was $13.6 million , $14.0 million and $13.9 million , respectively. We review long-lived assets for recoverability whenever events or changes in circumstances indicate that carrying amounts of an asset group may not be recoverable. Our asset groups are established by determining the lowest level of cash flows available. If the estimated undiscounted cash flows are less than the carrying amounts of such assets, we recognize an impairment loss in an amount necessary to write down the assets to fair value as estimated from expected future discounted cash flows. Estimating the fair value of these assets is judgmental in nature and involves the use of significant estimates and assumptions. We base our fair value estimates on assumptions we believe to be reasonable, but that are inherently uncertain.
Revenue Recognition	We recognize revenue when our performance obligation has been satisfied and control of products has been transferred to a customer, which typically occurs upon shipment. Revenue is measured based on the amount of consideration we expect to receive in exchange for the transfer of goods or services. Returns and allowances are used to record estimates of returns or allowances resulting from quality, delivery, discounts or other issues affecting the value of receivables. This amount is estimated based on historical trends and current market conditions, with the offset to revenues. Revenue is measured based on terms and conditions specified in contracts or purchase orders with customers. We have long-term contracts with some customers that govern overall terms and conditions which are accompanied by purchase orders that define specific order quantities and/or price. We have many customers with which we conduct business outlined in purchase orders without a long-term contract. We generally do not have customer contracts with minimum order quantity requirements. Amount and Timing of Revenue Recognition The transaction price is based on the consideration to which the Company will be entitled in exchange for transferring control of a product to the customer. This is defined in a purchase order or in a separate pricing arrangement and represents the stand-alone selling price. Our payment terms vary by customer. None of the Company's business arrangements as of December 31, 2019 , contained a significant financing component. We typically do not have multiple performance obligations requiring us to allocate a transaction price. We recognize revenue at the point in time when we satisfy a performance obligation by transferring control of a product to a customer, usually at a designated shipping point and in accordance with customer specifications. We make estimates for potential customer returns or adjustments based on historical experience, which reduce revenues. Other Matters Shipping and handling costs billed to customers are recorded in revenues and costs associated with outbound freight are generally accounted for as a fulfillment cost and are included in cost of revenues. We generally do not provide for extended warranties or material customer incentives. Our customers typically do not have a general right of return for our products.
Income Taxes	We recognize deferred tax assets and liabilities for the expected future tax consequences of events that have been included in our financial statements or tax returns. Deferred tax assets and liabilities are determined based on the difference between the financial statements and tax basis of assets and liabilities based on enacted tax laws and rates expected to be in place when the deferred tax items are realized. In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that a portion of the deferred tax assets will not be realized. We provide a valuation allowance for deferred tax assets when it is more likely than not that a portion of such deferred tax assets will not be realized. We evaluate tax positions for recognition by determining, based on the weight of available evidence, whether it is more likely than not the position will be sustained upon audit. Any interest and penalties related to our uncertain tax positions are recognized in income tax expense.
Comprehensive Income (Loss)	Comprehensive income (loss) reflects the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources including foreign currency translation, derivative instruments and pension and other post-retirement adjustments.
Fair Value of Financial Instruments	The fair value framework requires the categorization of assets and liabilities into three levels based upon the assumptions (i.e., inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. The three levels are defined as follows: Level 1 - Unadjusted quoted prices in active markets for identical assets and liabilities. Level 2 - Observable inputs other than those included in Level 1. For example, quoted prices for similar assets or liabilities in active markets and inactive markets. Level 3 - Significant unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability.
Concentrations of Credit Risk	Financial instruments that potentially subject us to concentrations of credit risk consist primarily of accounts receivable. We sell products to various companies throughout the world in the ordinary course of business. We routinely assess the financial strength of our customers and maintain allowances for anticipated losses. As of December 31, 2019 and 2018 , receivables from our largest customers, A.B. Volvo, Daimler Trucks, Caterpillar, Navistar, John Deere and PACCAR, represented approximately 62% and 66% of total receivables, respectively.
Foreign Currency Translation	Our functional currency is the local currency. Accordingly, all assets and liabilities of our foreign subsidiaries are translated using exchange rates in effect at the end of the period; revenue and costs are translated using average exchange rates for the period. The related translation adjustments are reported in accumulated other comprehensive income (loss) in stockholders’ equity. Translation gains and losses arising from transactions denominated in a currency other than the functional currency of the entity are included in the results of operations.
Foreign Currency Forward Exchange Contracts	We use forward exchange contracts to hedge certain foreign currency transaction exposures. We estimate our projected revenues and purchases in certain foreign currencies or locations and hedge a portion of the anticipated long or short position. The contracts typically run from one month to eighteen months. All forward foreign exchange contracts that are not designated as hedging instruments have been marked-to-market and the fair value of contracts recorded in the Consolidated Balance Sheets with the offsetting non-cash gain or loss recorded in our Consolidated Statements of Operations. For forward contracts that are designated as hedging instruments, the gains and losses are recorded in accumulated other comprehensive income (loss) and recognized in the Consolidated Statement of Operations when the contracts are settled. We do not hold or issue foreign exchange options or forward contracts for trading purposes.
Interest Rate Swap Agreement	We use an interest rate swap agreement to fix the interest rate on a portion of our variable interest debt thereby reducing exposure to interest rate changes. The interest rate swap agreement was not designated as a hedging instrument; therefore, the interest rate swap agreement has been marked-to-market and the fair value of the agreement recorded in the Consolidated Balance Sheets with the offsetting gain or loss recorded in interest and other expense in our Consolidated Statements of Operations.
Recently Issued Accounting Pronouncements	In July 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2019-07, "Codification Updates to SEC Sections". ASU No. 2019-07 clarifies or improves the disclosure and presentation requirements of a variety of codification topics by aligning them with the SEC's regulations, thereby eliminating redundancies. This ASU is effective upon issuance and did not have a significant impact on the Company's consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326)". The ASU requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. The FASB subsequently issued ASU No. 2018-19, "Codification Improvements to Topic 326: Financial Instruments - Credit Losses", in November 2018 which provided further guidance on assessment of receivables for operating leases. ASU No. 2019-04, "Codification Improvements to Topic 326, Topic 815 and Topic 825" and ASU No. 2019-05, "Targeted Transition Relief", that were issued in April and May of 2019 do not materially impact the Company. In November 2019, the FASB issued ASU No. 2019-11, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses", which further clarified and improved the Codification to make it easier to understand and apply. The Company anticipates ASU 2016-13, ASU 2018-19 and ASU 2019-11 will apply to its trade receivables and will not have a material impact on the reported value of such receivables. We expect to implement ASU No. 2016-13, 2018-19 and 2019-11 on the effective date of January 1, 2020. In December 2019, the FASB issued ASU No. 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes". The ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and otherwise clarifies and amends existing guidance. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020. We are evaluating the effect this ASU will have on the Company. Accounting Pronouncements Implemented During the Year Ended December 31, 2019 In June 2018, the FASB issued ASU No. 2018-07, "Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting". The ASU changed the measurement date for determining the fair value of share awards to nonemployees to the grant date and requires the consideration of the probability of satisfying performance obligations in assessing the awards. The ASU did not have a material impact on our recognition of share-based payments for nonemployees. Lease Accounting Guidance In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" followed by ASU No. 2018-11, "Leases (Topic 842): Targeted Improvements", issued in July 2018. These ASUs are intended to increase transparency and comparability among companies by recognizing lease assets and liabilities and disclosing key information about leasing arrangements. ASU 2016-02 was adopted by the Company on January 1, 2019. In accordance with Topic 842, we elected not to recognize lease assets and lease liabilities for leases with a term of twelve months or less and elected to not separate lease and non-lease components. We elected the transition method option under ASU 2018-11 with the package of practical expedients that permits the Company to: (a) not reassess whether expired or existing contracts contain leases, (b) not reassess lease classification for existing or expired leases and (c) not consider whether previously capitalized initial direct costs would be appropriate under the new standard. We recorded a right-of-use asset of $21.2 million and a lease liability of $22.2 million upon adoption. We also elected the option to apply the new leasing standard on the date of adoption and recognize a cumulative-effect transition adjustment to the opening balance of retained earnings in the period of adoption resulting in a cumulative effect as of January 1, 2019 of $0.1 million . Refer to Note 6 for further details.
