Organization Consolidation And Presentation Of Financial Statements [Abstract]
Overview	Note 1 – Overview Gentherm Incorporated is a global developer and marketer of innovative thermal management technologies for a broad range of heating and cooling and temperature control applications. Unless the context otherwise requires, the terms “Gentherm”, “Company”, “we”, “us” and “our” used herein refer to Gentherm Incorporated and its consolidated subsidiaries. Our products provide solutions for automotive passenger climate comfort and convenience, battery thermal management and cell connecting systems, as well as patient temperature management within the health care industry. Our automotive products can be found in the vehicles of nearly all major automotive manufacturers operating in North America and Europe, and several major automotive manufacturers in Asia. The Company operates in locations aligned with its major customers’ product strategies to provide locally enhanced design, integration and production capabilities. The Company is also developing a number of new technologies and products that will help enable improvements to existing products and to create new product applications for existing and new markets. On February 1, 2019, the Company completed the divestiture of its environmental test equipment business, Cincinnati Sub-Zero industrial chamber business (“CSZ-IC”) and on October 1, 2019, the Company completed the divestiture of its remote power generation systems business, Gentherm Global Power Technologies (“GPT”). The Company’s consolidated condensed financial statements herein include the results of CSZ-IC and GPT through their respective dates of divestiture. CSZ-IC and GPT are not subject to discontinued operations classification. On April 1, 2019, Gentherm acquired Stihler Electronic GmbH (“Stihler”), a leading developer and manufacturer of patient and blood temperature management systems. The acquisition was accounted for as a business combination. Basis of Presentation The unaudited consolidated condensed financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to those rules and regulations. The information furnished in the consolidated condensed financial statements include all adjustments (consisting of only normal, recurring adjustments), considered necessary to present fairly the results of operations, financial position and cash flows of the Company. These financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. The operating results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. Impact of COVID-19 The COVID-19 pandemic began in China around December 2019. The impact of the outbreak quickly expanded beyond China and its surrounding region. The COVID-19 pandemic significantly disrupted and adversely impacted global economic activity and the global automotive markets in the first half of 2020, which had significant negative impacts on Gentherm’s financial performance in the first half of 2020. During the first quarter of 2020, customer plants in North America and Europe were closed beginning in the second half of March due to the pandemic. This resulted in temporary, partial closures of several of our manufacturing facilities in North America and Europe by the end of March 2020. Customer plants and our manufacturing facilities in Asia were closed for several weeks in February and operated at reduced volumes in March, In preparing these financial statements, management was required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. These estimates and assumptions are based on our historical experience, the terms of existing contracts, our evaluation of trends in the industry, information provided by our customers and suppliers and information available from other outside sources, as appropriate. These estimates and assumptions are subject to an inherent degree of uncertainty. We are not presently aware of any events or circumstances that would require us to update such estimates and assumptions or revise the carrying value of our assets or liabilities. Our estimates may change, however, as new events occur and additional information is obtained . As a result, actual results may differ significantly from our estimates , and any such differences may be material to our financial statements .

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
New Accounting Pronouncements	Note 2 – New Accounting Pronouncements Recently Adopted Accounting Pronouncements Expected Credit Losses In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019. The Company adopted ASU 2016-13 as of January 1, 2020 and there was no significant impact on its consolidated condensed financial statements and related disclosures as a result. The Company considered, among other things, the current and expected future economic and market conditions related to the COVID-19 pandemic and determined that the estimate of credit losses was not significantly impacted. Cloud Computing Arrangements That Are Service Contracts In August 2018, the FASB issued ASU 2018-15, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” ASU 2018-15 requires implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement if those costs would be capitalized by the customer in a software licensing arrangement under the internal-use software guidance. ASU 2018-15 is effective for annual and interim periods beginning after December 15, 2019. The Company adopted ASU 2018-15 as of January 1, 2020 and there was no significant impact on its consolidated condensed financial statements and related disclosures as a result. Fair Value Measurement In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement.” ASU 2018-13 removes certain disclosure requirements, including (i) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, (ii) the policy for timing of transfer between levels, and (iii) the valuation processes for Level 3 fair value measurements. ASU 2018-13 also adds new disclosure requirements, including (i) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and (ii) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. ASU 2018-13 is effective for annual and interim periods beginning after December 15, 2019. The Company adopted ASU 2018-13 as of January 1, 2020 and there was no significant impact on its consolidated condensed financial statements and related disclosures as a result. Recently Issued Accounting Pronouncements Not Yet Adopted Retirement Benefits In August 2018, the FASB issued ASU 2018-14, “Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans.” ASU 2018-14 removes certain disclosure requirements, including (i) the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year, and (ii) the amount and timing of plan assets expected to be returned to the employer. ASU 2018-14 also adds new disclosure requirements, including (i) the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates and (ii) an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. ASU 2018-14 is effective for annual periods ending after December 15, 2020. Early adoption of the amendments in this update is permitted. The Company is currently in the process of determining the impact the implementation of ASU 2018-14 will have on the Company’s financial statement note disclosures. Income Taxes In December 2019, the FASB issued ASU No. 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes". This ASU simplifies the accounting for income taxes by removing certain exceptions previously included in the guidance. In addition, the ASU amends existing guidance to improve consistent application. ASU 2019-12 is effective for annual reporting periods beginning after December 15, 2020, and interim periods within those reporting periods. Early adoption of the amendments in this update is permitted. The adoption of this standard is not expected to have a significant impact on the Company’s financial statements or financial disclosures Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of Effects of Reference Rate Reform on Financial Reporting”. ASU 2020-04 provides practical expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The expedients and exceptions provided by the amendments in this update apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued as a result of reference rate reform. These amendments are not applicable to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. ASU No. 2020-04 is effective as of March 12, 2020 through December 31, 2022 and may be applied to contract modifications and hedging relationships from the beginning of an interim period that includes or is subsequent to March 12, 2020. The Company will adopt this standard when LIBOR is discontinued and does not expect a material impact to its consolidated financial statements.

Restructuring And Related Activities [Abstract]
Restructuring	Note 4 – Restructuring Manufacturing Footprint Rationalization On September 23, 2019, the Company committed to a restructuring plan to improve the Company’s manufacturing productivity and rationalize its footprint. Under this plan, the Company will relocate and consolidate certain existing automotive manufacturing and, as a result, reduce the number of plants by two. On March 20, 2020, the Company announced the initial phase of this restructuring plan, which includes the consolidation of all North American electronics manufacturing to Celaya, Mexico. This will result in the closure of the Burlington, Canada facility, and the transfer of electronics manufacturing from Acuña, Mexico. During the second quarter of 2020, due to circumstances arising from the COVID-19 pandemic, management adjusted the plan to proactively manage its cash position. Adjustments to the plan have resulted in changes to the estimated number of employee separations and total costs to execute the plan. During the three and nine months ended September 30, 2020, the Company recognized restructuring expense of $116 and $(1,327) for employee separation costs, respectively, $122 and $564 for accelerated depreciation, respectively, and $0 and $16 for other costs, respectively. The net activity for the nine months ended September 30, 2020 is primarily related to a reduction in the estimates of previously recognized employee separation costs. During the three months ended September 30, 2019, the Company recognized restructuring expense of $5,200 for employee separation costs, and $1,612 of accelerated depreciation and fixed asset impairment. The Company has recorded approximately $6,203 of restructuring expenses since the inception of this program. Under the revised restructuring plan, the Company expects to incur total costs of between $16,000 and $19,000, of which $13,000 and $16,000 are expected to be cash expenditures. The total expected costs include employee separation costs of between $6,500 and $7,500, capital expenditures of between $3,500 and $4,500 and non-cash expenses for accelerated depreciation and impairment of fixed assets of approximately $3,000. The Company also expects to incur other transition costs including recruiting, relocation, and machinery and equipment move and set up costs of between $3,000 and $4,000. The actions under this plan are expected to be substantially completed by the end of 2021. The actual timing, costs and savings of the plan may differ materially from the Company’s current expectations and estimates. Other Restructuring Activities As part of the Company’s continued efforts to optimize its cost structure, the Company has undertaken several discrete restructuring actions. During the three and nine months ended September 30, 2020, the Company recognized $64 and $3,978 of employee separation costs, respectively, and $ (18) and $ 221 of other related costs, respectively. During the three and nine months ended September 30, 2019 , the Company recognized $ and $ 2,726 of employee separation costs, respectively, and $ 385 and $ 734 of other related costs, respectively. In addition, during the three and nine months ended September 30 , 2019, the Company recognized $ 0 and $ 425 of asset impairment loss , respectively . These restructuring expenses were primarily associated with restructuring actions focused on the rotation of our manufacturing footprint to lower cost locations and the reduction of global overhead costs. The Company will continue to explore opportunities to improve its future profitability and competitiveness. These actions may result in the recognition of additional restructuring charges that could be material. GPT and CSZ-IC Costs associated with the divestiture process were classified as restructuring. During the three and nine months ended September 30, 2019, the Company recognized $0 and $251 of employee separation costs, respectively, and $0 and $861 of other related costs, related to the marketing of GPT and CSZ-IC, respectively. The Company recorded approximately $2,303 of restructuring expenses since inception of this program and it is complete.

Earnings Per Share [Abstract]
Earnings per Share	Note 5 – Basic earnings per share are computed by dividing net income by the weighted average number of shares of Common Stock outstanding during the period. The Company’s diluted earnings per share give effect to all potential shares of Common Stock outstanding during a period that do not have an anti-dilutive impact to the calculation. In computing the diluted earnings per share, the treasury stock method is used in determining the number of shares assumed to be issued from the exercise of Common Stock equivalents. The following table illustrates earnings per share and the weighted average shares outstanding used in calculating basic and diluted earnings per share: Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 Net income $ 24,146 $ 15,887 $ 25,697 $ 27,052 Basic weighted average shares of Common Stock outstanding 32,623,532 32,838,636 32,631,423 33,282,584 Dilutive effect of stock options, restricted stock awards and restricted stock units 334,907 94,043 292,590 135,971 Diluted weighted average shares of Common Stock outstanding 32,958,439 32,932,679 32,924,013 33,418,555 Basic earnings per share $ 0.74 $ 0.48 $ 0.79 $ 0.81 Diluted earnings per share $ 0.73 $ 0.48 $ 0.78 $ 0.81 The following table represents Common Stock issuable upon the exercise of certain stock options that have been excluded from the diluted earnings calculation because the effect of their inclusion would be anti-dilutive.

Income Tax Disclosure [Abstract]
Income Taxes	Note 8 – Income Taxes At the end of each interim period, the Company makes its best estimate of the annual expected effective income tax rate and applies that rate to its ordinary year-to-date earnings or loss. The income tax provision or benefit related to unusual or infrequent items, if applicable, that will be separately reported or reported net of their related tax effects are individually computed and recognized in the interim period in which those items occur. In addition, the effect of changes in enacted tax laws or rates, tax status, judgment on the realizability of a beginning-of-the-year deferred tax asset in future years or income tax contingencies is recognized in the interim period in which the change occurs. The computation of the annual expected effective income tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected pre-tax income (or loss) for the year, projections of the proportion of income (and/or loss) earned and taxed in respective jurisdictions, permanent and temporary differences, and the likelihood of the realizability of deferred tax assets generated in the current year. Jurisdictions with a projected loss for the year or a year-to-date loss for which no tax benefit or expense can be recognized due to a valuation allowance are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the composition and timing of actual earnings compared to annual projections. The estimates used to compute the provision or benefit for income taxes may change as new events occur, additional information is obtained or as our tax environment changes. To the extent that the expected annual effective income tax rate changes, the effect of the change on prior interim periods is included in the income tax provision in the period in which the change in estimate occurs. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was signed into U.S. law. The CARES Act provides a stimulus and assistance package intended to address the impact of the COVID-19 pandemic, including tax relief and government loans, grants and investments. As permitted by the CARES Act, the Company has deferred the payment of payroll taxes each quarter for the remainder of 2020 to be paid in the fourth quarters of 2021 and 2022. A summary of the provision for income taxes and the corresponding effective tax rate for the three and nine months ended September 30, 2020 and 2019, is shown below: Three Months Ended Nine Months Ended September 30, September 30, 2020 2019 2020 2019 Income tax expense $ 9,603 $ 6,771 $ 15,214 $ 19,214 Earnings before income tax $ 33,749 $ 22,658 $ 40,911 $ 46,266 Effective tax rate 28.5 % 29.9 % 37.2 % 41.5 % For the nine months ended September 30, 2020, the Company recognized a tax expense of $3,358 related to multi-year international audit settlements and closures. For the nine months ended September 30, 2019, the Company recognized impairment loss of $21,206 for which no tax benefit was provided. The annual effective tax rates differ from the U.S. statutory rate primarily due to foreign rates which differ from those in the U.S., U.S. taxes on foreign earnings, the realization of certain business tax credits, including research and development and foreign tax credits, the applicable withholding taxes on the projected future repatriations of the earnings from the Company’s non-U.S. operations that are not considered permanently reinvested and the effect of the discrete items described above.

The investment was accounted for as an asset acquisition of defensive intangible assets and will be amortized over six years. On June 19, 2020, Gentherm sold patents from a non-core business for $2,055. The gain on sale of $1,978 was recorded in Other (loss) income on the consolidated condensed statements of income. In addition to annual impairment testing, which is performed in the fourth quarter of each fiscal year, the Company continuously monitors for events and circumstances that could negatively impact the key assumptions used in determining fair value, including long-term revenue growth projections, profitability, discount rates, recent market valuations from transactions by comparable companies, volatility in the Company's market capitalization, and general industry, market and macroeconomic conditions, requiring interim impairment testing. We are not presently aware of any events or circumstances that would require us to revise the carrying value of our assets or liabilities as of September 30, 2020.

The Amended Credit Agreement amended and restated in its entirety the Credit Agreement. The outstanding principal and interest of the U.S. Revolving Note under the Credit Agreement continued and constitute obligations under the Amended Credit Agreement. The Amended Credit Agreement increased the U.S. Revolving Note from $350,000 to $475,000 and extended the maturity from March 17, 2021 to June 27, 2024. Subject to specified conditions that would not be satisfied as of September 30, 2020, the Company can request an increase to the U.S. Revolving Note in an aggregate amount of $175,000. The Amended Credit Agreement also provides $15,000 availability for the issuance of letters of credit and a maximum of $40,000 for swing line borrowing. Any amount of the facility utilized for letters of credit or swing line loans outstanding will reduce the amount available under the Amended Credit Agreement. The Company had no outstanding letters of credit issued under the Amended Credit Agreement as of September 30, 2020 and December 31, 2019. The U.S. borrowers and guarantors participating in the Amended Credit Agreement also entered into a related amended and restated pledge and security agreement. The amended and restated pledge and security agreement grants a security interest to the lenders in substantially all of the personal property of the Company and its U.S. subsidiaries designated as borrowers to secure their respective obligations under the Amended Credit Agreement, including the stock and membership interests of specified subsidiaries (limited to 66% of the stock in the case of certain non-U.S. subsidiaries). In addition to the security obligations, all obligations under the Amended Credit Agreement are unconditionally guaranteed by certain of the Company’s subsidiaries. The Amended Credit Agreement restricts, among other things, the amount of dividend payments the Company can make to shareholders. The Amended Credit Agreement contains covenants, that, among other things, (i) prohibit or limit the ability of the borrowers and any material subsidiary to incur additional indebtedness, create liens, pay dividends, make certain types of investments (including acquisitions), enter into certain types of transactions with affiliates, prepay other indebtedness, sell assets, merge with other companies or enter into certain other transactions outside the ordinary course of business, and (ii) require that Gentherm maintain a minimum Consolidated Interest Coverage Ratio and Consolidated Leverage Ratio (based on consolidated EBITDA for the applicable trailing 12-month period as defined in the Amended Credit Agreement) as of the end of any fiscal quarter. The Amended Credit Agreement also contains customary events of default. As of September Under the Amended Credit Agreement, U.S. Dollar denominated loans bear interest at either a base rate (“Base Rate Loans”) or Eurocurrency rate (“Eurocurrency Rate Loans”), plus a margin (“Applicable Rate”). The rate for Base Rate Loans is equal to the highest of the Federal Funds Rate (0.09% at September 30, 2020) plus 0.50%, Bank of America’s prime rate (3.25% at September 30, 2020), or the Eurocurrency rate plus 1.00%. The rate for Eurocurrency Rate Loans denominated in U.S. Dollars is equal to the London Interbank Offered Rate (0.15% at September 30, 2020). All loans denominated in a currency other than the U.S. Dollar must be Eurocurrency Rate Loans. Interest is payable at least quarterly. The Applicable Rate varies based on the Consolidated Leverage Ratio reported by the Company. As long as the Company is not in default of the terms and conditions of the Amended Credit Agreement, the lowest and highest possible Applicable Rate is 1.25% and 2.25%, respectively, for Eurocurrency Rate Loans and 0.25% and 1.25%, respectively, for Base Rate Loans. In March 2020, the Company increased its borrowings under the Amended Credit Agreement by $169,546 as a safeguard to increase its cash position and provide additional financial flexibility due to the COVID-19 pandemic. The proceeds have been and will continue to be used for working capital and for other general corporate purposes permitted by the Amended Credit Agreement. During the second and third quarters of 2020, the Company repaid a net amount of $38,680 of the amounts outstanding under the Amended Credit Agreement.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Financial Instruments	Note 13 – Financial Instruments Cash, Cash Equivalents and Restricted Cash The Company has cash that is legally restricted as to use or withdrawal. A reconciliation of Cash and cash equivalents on the consolidated condensed balance sheets to Cash, cash equivalents and Restricted cash presented on the consolidated condensed statements of cash flows is as follows: September 30, 2020 December 31, 2019 Cash and cash equivalents presented in the consolidated condensed balance sheets $ 226,533 $ 50,443 Restricted cash 2,506 2,505 Cash, cash equivalents and restricted cash presented in the consolidated condensed statements of cash flows $ 229,039 $ 52,948 Derivative Financial Instruments The Company is exposed to various market risks including, but not limited to, changes in foreign currency exchange rates, changes in interest rates and commodity price fluctuations. Market risks for changes in interest rates relate primarily to its debt obligations under the Amended Credit Agreement. Foreign currency exchange risks are attributable to sales to foreign customers and purchases from foreign suppliers not denominated in a location’s functional currency, foreign plant operations, intercompany indebtedness, intercompany investments and include exposures to the Euro, Mexican Peso, Canadian Dollar, Hungarian Forint, Macedonian Denar, Ukrainian Hryvnia, Japanese Yen, Chinese Renminbi, Korean Won and Vietnamese Dong. The Company regularly enters into derivative contracts with the objective of managing its financial and operational exposure arising from these risks by offsetting gains and losses on the underlying exposures with gains and losses on the financial instruments used to hedge them. The maximum length of time over which the Company hedges its exposure to foreign currency exchange risks is fifteen months. The Company had foreign currency derivative contracts with a notional value of $20,752 and $14,449 outstanding as of September 30, 2020 and December 31, 2019, respectively. The Company does not enter into derivative financial instruments for speculative or trading purposes. The Company’s hedging relationships are formally documented at the inception of the hedge, and hedges must be highly effective in offsetting changes to future cash flows on hedged transactions both at the inception of a hedge and on an ongoing basis to be designated for hedge accounting treatment. For derivative contracts which can be classified as a cash flow hedge, the effective portion of the change in the fair value of the derivative is recorded to Accumulated other comprehensive loss in the consolidated condensed balance sheets. When the underlying hedge transaction is realized, the gain or loss included in Accumulated other comprehensive loss is recorded in earnings in the consolidated condensed statements of income on the same line as the gain or loss on the hedged item attributable to the hedged risk. The Company records the ineffective portion of foreign currency hedging instruments, if any, to Foreign currency (loss) gain in the consolidated condensed statements of income. The Company uses an income approach to value derivative instruments, analyzing quoted market prices to calculate the forward values and then discounting such forward values to the present value using benchmark rates at commonly quoted intervals for the instrument’s full term.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 14 – Fair Value Measurements Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurements are based on one or more of the following three valuation techniques: Market : This approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. Income : This approach uses valuation techniques to convert future amounts to a single present value amount based on current market expectations. Cost : This approach is based on the amount that would be required to replace the service capacity of an asset (replacement cost). The Company uses the following fair value hierarchy to measure fair value into three broad levels, which are described below: Level 1 : Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs. Level 2 : Inputs, other than quoted market prices included in Level 1, that are observable either directly or indirectly for the asset or liability. Level 3 : Unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs. Items Measured at Fair Value on a Recurring Basis Except for derivative instruments (see Note 13), pension plan assets and a corporate owned life insurance policy, the Company had no material financial assets and liabilities that were carried at fair value at September Items Measured at Fair Value on a Nonrecurring Basis The Company measures certain assets and liabilities at fair value on a non-recurring basis. As these nonrecurring fair value measurements are generally determined using unobservable inputs, these fair value measurements are classified within Level 3 of the fair value hierarchy. As of September Items Not Carried at Fair Value The Company uses an income valuation technique to measure the fair values of its debt instruments by converting amounts of future cash flows to a single present value amount using rates based on current market expectations (Level 2 inputs). As of September September

Impact of COVID-19	Impact of COVID-19 The COVID-19 pandemic began in China around December 2019. The impact of the outbreak quickly expanded beyond China and its surrounding region. The COVID-19 pandemic significantly disrupted and adversely impacted global economic activity and the global automotive markets in the first half of 2020, which had significant negative impacts on Gentherm’s financial performance in the first half of 2020. During the first quarter of 2020, customer plants in North America and Europe were closed beginning in the second half of March due to the pandemic. This resulted in temporary, partial closures of several of our manufacturing facilities in North America and Europe by the end of March 2020. Customer plants and our manufacturing facilities in Asia were closed for several weeks in February and operated at reduced volumes in March, In preparing these financial statements, management was required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. These estimates and assumptions are based on our historical experience, the terms of existing contracts, our evaluation of trends in the industry, information provided by our customers and suppliers and information available from other outside sources, as appropriate. These estimates and assumptions are subject to an inherent degree of uncertainty. We are not presently aware of any events or circumstances that would require us to update such estimates and assumptions or revise the carrying value of our assets or liabilities. Our estimates may change, however, as new events occur and additional information is obtained . As a result, actual results may differ significantly from our estimates , and any such differences may be material to our financial statements .
