Company And Subsequent Events [Abstract]
The Company and Subsequent Events	Note 1 – The Company and Subsequent Events Gentherm Incorporated is a global technology and industry leader in the design, development, and manufacturing of innovative thermal management technologies and automotive cable systems. Unless the context otherwise requires, the terms “Company”, “we”, “us” and “our” used herein refer to Gentherm Incorporated and its consolidated subsidiaries. Our products provide solutions for automotive passenger comfort and convenience, battery thermal management, remote power generation, patient temperature management, and other consumer and industrial temperature control needs. Our automotive products can be found on the vehicles of nearly all major automotive manufacturers operating in North America, Europe and Asia. We operate in locations aligned with our major customers’ product strategies in order to provide locally enhanced design, integration and production capabilities and to identify future thermal technology product opportunities in both automotive and other markets. We concentrate our research on the development of new technologies that will enable new products, improve overall effectiveness of existing products and maximize customer satisfaction. We also focus on developing new design applications from our existing technologies to create new products and market opportunities for thermal comfort solutions. North American Reorganization On January 4, 2016 and January 5, 2016, the Company completed reorganization transactions (the “Reorganization”) related to our North American business (the “Windsor Operations”). As part of our original integration plan to eliminate redundancies associated with the 2011 acquisition of Gentherm GmbH (formally named W.E.T. Automotive Systems AG), the Windsor Operations have been consolidated into our existing European and North American facilities. As a result of the Reorganization, some of the business activities previously performed by the Windsor Operations will now be performed by other subsidiaries. Related to the Reorganization, the Company declared an intercompany dividend, incurred and paid a related withholding tax to the Canadian Revenue Agency and recorded a tax expense of approximately $6,300, during the first quarter of 2016. Later during the quarter, a further intercompany dividend was declared and paid resulting in an additional $1,300 withholding tax being paid and expensed and the Company changed its assessment of the potential for further dividends and accrued and expensed, but did not pay, an estimated final withholding tax amount totaling $2,000. This estimate is expected to cover the amount of all future intercompany dividends needed to distribute the remaining earnings of the subsidiary to its parent in conjunction with the final liquidation of the subsidiary. In addition to the $9,600 in combined withholding taxes, the Reorganization will require the Company to make a one-time income tax payment of approximately $32,000. The one-time income tax payment was accrued during the first quarter of 2016; however, the Company also recorded an offsetting deferred charge for approximately the same amount because the one-time income tax payment will result in tax deductions against income taxes in future periods. Therefore, the income tax payment did not have a material impact on the Company’s earnings during the first quarter of 2016 and is not expected to have a material impact in any future fiscal quarter. The income tax payment will be paid during 2017 and is included in accrued liabilities as of June 30, 2016. The deferred charge is included in other non-current assets as of June 30, 2016. Cincinnati Sub-Zero On April 1, 2016, we acquired all of the equity of privately-held Cincinnati Sub-Zero Products, LLC (“CSZ”) and related assets in an all-cash transaction. CSZ manufactures both high quality patient temperature management systems for the health care industry and custom testing equipment used by a wide range of industrial manufacturing companies for product testing. CSZ’s world headquarters and manufacturing operations are located in Cincinnati, Ohio. See Note 3, “Cincinnati Sub-Zero Acquisition” for additional information regarding CSZ. Subsequent Events We have evaluated subsequent events through the date that our consolidated condensed financial statements are issued. No events have taken place that meet the definition of a subsequent event requiring adjustments to or disclosures in this filing.

Basis Of Presentation And New Accounting Pronouncements [Abstract]
Basis of Presentation and New Accounting Pronouncements	Note 2 – Basis of Presentation and New Accounting Pronouncements The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in the audited annual consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, all adjustments, consisting of normal recurring items, considered necessary for a fair presentation of our results of operations, financial position and cash flows have been included. The balance sheet as of December 31, 2015 was derived from audited annual consolidated financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. Certain reclassifications of prior year’s amounts have been made to conform with the current year’s presentation. Operating results for the six months ended June 30, 2016 is not necessarily indicative of the results that may be expected for the year ending December 31, 2016. These consolidated condensed financial statements should be read in conjunction with the financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2015. Financial Instruments In January, 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” ASU 2016-01 requires equity investments not accounted for under the equity method of accounting or result in consolidation of an investee, that have readily determinable fair values to be measured at fair value with changes in the fair value recognized in net income. The update simplifies the impairment assessment for equity investments without readily determinable fair values by requiring assessment for impairment qualitatively, similar to the impairment assessment currently used for long-lived assets, goodwill and indefinite-lived intangible assets. The amendments in this update also change the disclosure requirements for financial instruments, including eliminating the requirement to disclose the method and significant assumptions used to estimate the fair value for financial instruments measured at amortized costs on the balance sheet. ASU 2016-01 is effective for fiscal years and interim periods beginning after December 15, 2017 and early adoption of the amendments in this update, in general, is not permitted. ASU 2016-01 is not expected to significantly impact the Company. Leases In February, 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires lessees to recognize on their balance sheet a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. Payments to be made in optional periods should be included in the measurement of lease assets and liabilities if the lessee is reasonably certain it will exercise an option to extend the lease or not exercise an option to terminate the lease. While ASU 2016-02 continues to differentiate between finance or capital leases and operating leases, the principal change from current lease accounting guidance is that lease assets and liabilities arising from operating leases should be recognized on the balance sheet. ASU 2016-02 is effective for fiscal years and interim periods beginning after December 15, 2018. Early adoption of the amendments in this update is permitted. Lessees are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach which includes a number of practical expedients, including the ability to use hindsight in evaluating lessee options to extend or terminate a lease. An entity that elects to apply the practical expedients will be required to recognize a right-of-use asset and lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payment that were tracked and disclosed under previous GAAP. We are currently in the process of determining the impact the implementation of ASU 2016-02 will have on the Company’s financial statements. Note 2 – Basis of Presentation and New Accounting Pronouncements – Continued Stock Compensation In March, 2016, the FASB issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Under the new standard, income tax benefits and deficiencies are to be recognized as income tax expense or benefit in the income statement and the tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity should also recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Excess tax benefits should be classified along with other income tax cash flows as an operating activity. In regards to forfeitures, the entity may make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. ASU 2016-09 is effective for fiscal years and interim periods beginning after December 15, 2016. Early adoption of the amendments in this update is permitted Revenue from Contracts with Customers In May, 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 was developed to enable financial statement users to better understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The update’s core principal is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Companies are to use a five-step contract review model to ensure revenue gets recognized, measured and disclosed in accordance with this principle. In April, 2016, the FASB issued ASU 2016-10, “Identifying Performance Obligations and Licensing” to, amongst other things, reduce the cost and complexity it takes to identify performance obligations in a contract (step two in the five-step contract review model). As a result, entities are not required to assess whether promised goods or services are performance obligations if they are immaterial in the context of the contract. In June, 2015, the FASB issued ASU 2015-14, “Deferral of the Effective Date.” As a result of this update, ASU 2014-09 and ASU 2016-10 will be effective for fiscal years and interim periods beginning after December 15, 2017. The amendments in these updates will be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect recognized at the date of initial application. Gentherm has developed a plan to complete the five-step contract review process for all existing contracts with customers. We are currently in the process of determining the impact the implementation of ASU 2014-09 and ASU 2016-10 will have on the Company’s financial statements. Inventory – Simplifying the Measurement of Inventory In July, 2015, the FASB issued ASU 2015-11, “ Inventory (Topic 330) Simplifying the Measurement of Inventory.” The update requires that inventory measured using any method other than last-in, first-out (LIFO) or the retail inventory method shall be measured at the lower of cost and net realizable value. ASU 2015-11 is effective for fiscal years and interim periods beginning after December 15, 2016 and is not expected to significantly impact the Company. Balance Sheet Classification of Deferred Taxes In November, 2015, the FASB issued ASU 2015-17, “ Income Taxes (Topic 740) Balance Sheet Classification of Deferred Taxes.” ASU 2015-17 no longer requires an entity to separate deferred income tax liabilities and assets into current and noncurrent amounts on the balance sheet. Instead, for each tax paying component and within each tax jurisdiction all deferred tax liabilities and assets, as well as related valuation allowance, shall be offset and presented as a single noncurrent amount. Entities will continue to not offset deferred tax liabilities and assets attributable to different tax-paying components of the entity or to different tax jurisdictions. Note 2 – Basis of Presentation and New Accounting Pronouncements – Continued ASU 2015-17 is effective for fiscal years and interim periods beginning after December 15, 2016, though earlier application is permitted. The update can be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. We anticipate adoption of ASU 2015-17 will impact our presentation of deferred tax liabilities and assets on the consolidated condensed balance sheets .

Cincinnati Sub-Zero Acquisition

Cincinnati Sub-Zero Acquisition	6 Months Ended
	Jun. 30, 2016
Business Combinations [Abstract]
Cincinnati Sub-Zero Acquisition	Note 3 – Cincinnati Sub-Zero Acquisition CSZ develops, manufactures and sells patient temperature management systems and product testing equipment. The patient temperature management systems regulate the body temperature of medical patients during and after surgery. The product testing equipment simulates temperature, humidity, altitude and vibration conditions and is customized for use in a wide variety of industrial manufacturing applications. Results of operations for CSZ are included in the Company’s consolidated condensed financial statements beginning April 1, 2016. CSZ contributed $16,978 in product revenues and a net loss of $1,644 for the three and six month periods ended June 30, 2016. Purchase Price Allocation The purchase price of $73,666, net of cash acquired of $985, has been allocated to the values of assets acquired and liabilities assumed as of April 1, 2016. The allocation of the purchase price is preliminary. The Company is in the process of obtaining additional information required to finalize the valuation. An appraisal is currently underway by an independent third party valuation firm to assist management in determining the fair value of acquired assets and assumed liabilities, including identifiable intangible assets. The final purchase price allocation may be materially different than the preliminary allocation recorded. The purchase price allocation is expected to be finalized by December 31, 2016. The preliminary allocation as of April 1, 2016 was as follows: Accounts receivable $ 10,790 Inventory 16,284 Prepaid expenses and other assets 1,144 Property and equipment 12,974 Customer relationships 11,600 Technology 3,200 Trade name 6,370 Goodwill 22,739 a Assumed liabilities (11,435 ) Net assets acquired 73,666 Cash acquired 985 Purchase price $ 74,651 (a) The preliminary amount recorded to goodwill is expected to change due to additional consideration owed to the seller for a tax gross up. The gross contractual amount due of accounts receivable is $11,126 of which $336 is expected to be uncollectible. The purchase price allocation includes an approximate $4,000 step-up in the underlying net book value of the inventory to its fair value. This inventory was sold to customers and expensed to cost of goods sold during the three month period ended June 30, 2016. Note 3 – Cincinnati Sub-Zero Acquisition – Continued Supplemental Pro Forma Information The unaudited pro forma combined historical results including the amounts of CSZ’s revenue and earnings that would have been included in the Company’s consolidated condensed statements of income had the acquisition date been January 1, 2016 or January 1, 2015 are as follows: Three Months Ended Six Months Ended 2015 2016 2015 Product revenues $ 221,136 $ 464,339 $ 449,638 Net income $ 17,456 $ 30,732 $ 37,366 Basic earnings per share $ 0.48 $ 0.84 $ 1.04 Diluted earnings per share $ 0.48 $ 0.84 $ 1.03 The pro forma information includes adjustments for the effect of the amortization of intangible assets recognized in the acquisition. This pro forma information is not indicative of future operating results. Goodwill We recorded goodwill of approximately $22,739 arising from the acquisition. The acquired goodwill represents intangible assets that do not qualify for separate recognition. It is estimated that all of the goodwill recognized will be deductible for income tax purposes. Intangible Assets In conjunction with the acquisition, intangible assets of $21,170 were recorded. The Company’s estimate of the fair value of these assets at the time of the acquisition is preliminary and will be determined with the assistance of an independent third-party valuation firm. As part of the estimated valuation, an estimated useful life for the assets was determined. Intangible assets, net consisted of the following: June 30, 2016 Gross Value Accumulated Net Value Useful Life Customer relationships $ 11,600 $ 193 $ 11,407 15 yrs Technology 3,200 130 3,070 5 -7 yrs Trade name 6,370 — 6,370 Indefinite Total $ 21,170 $ 323 $ 20,847 Amortization expense of $323 for the three and six months ended June 30, 2016 was recorded as follows: Three and Six Months Ended Product revenues $ 193 Selling, general and administrative expense 130 Note 3 – Cincinnati Sub-Zero Acquisition – Continued Amortization expense for the prospective five years is estimated to be as follows: July 1, 2016 through December 31, 2016 $ 647 2017 $ 1,293 2018 $ 1,293 2019 $ 1,293 2020 $ 1,293 2021 $ 1,293 Property, Plant & Equipment Property and equipment consist of the following: Asset category Useful life Amount Land Indefinite $ 1,630 Buildings 20 yrs 6,066 Machinery and equipment 5-7 yrs 3,867 Computer hardware and software 3-5 yrs 450 Assets under construction 961 $ 12,974

Earnings per Share

Earnings Per Share [Abstract]
Earnings per Share	Note 4 – Basic earnings per share are computed by dividing net income by the weighted average number of shares of stock outstanding during the period. The Company’s diluted earnings per share give effect to all potential 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 summarizes the Common Stock included in the basic and diluted shares, as disclosed on the face of the consolidated condensed statements of income: Three Months Six Months 2016 2015 2016 2015 Weighted average number of shares for calculation of basic EPS 36,442,296 35,970,992 36,399,635 35,870,649 Stock options under equity incentive plans 194,922 613,858 172,595 557,858 Weighted average number of shares for calculation of diluted EPS 36,637,218 36,584,850 36,572,230 36,428,507 The accompanying 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.

Segment Reporting [Abstract]
Segment Reporting	Note 5 – Segment Reporting Segment information is used by management for making strategic operating decisions for the Company. As discussed in Note 3, Gentherm acquired CSZ on April 1, 2016. The acquisition enhances key elements of our business strategy by expanding the breadth of products derived from core thermal technologies and the markets in which they are applied, such as medical equipment and environmental chamber testing. Management evaluates the performance of the Company’s segments based primarily on operating income or loss. The Company’s reportable segments are as follows: Automotive · Industrial – the combined operating results of Gentherm Global Power Technologies (“GPT”), CSZ and Gentherm’s advanced research and development division. Advanced research and development includes efforts focused on improving the efficiency of thermoelectric technologies and advanced heating wire technology as well as other applications. The segment includes government sponsored research projects. Reconciling Items – The tables below present segment information about the reported product revenues, depreciation and amortization and operating income (loss) of the Company for three and six month periods ended June 30, 2016 and 2015. With the exception of goodwill, asset information by segment is not reported since the Company does not manage assets at a segment level. As of June 30, 2016, goodwill assigned to our Automotive and Industrial segments were $22,119 and $28,890, respectively. As of June 30, 2015, goodwill assigned to our Automotive and Industrial segments were $22,167 and $6,305, respectively.

Debt Disclosure [Abstract]
Debt	Note 6 – Debt Credit Agreement On March 17, 2016, the Company, together with certain direct and indirect subsidiaries, executed the Second Amendment to the Credit Agreement (the “Amended Credit Agreement”) with a consortium of lenders and Bank of America, N.A., as administrative agent. The Amended Credit Agreement eliminated without penalty the U.S. Term and Europe Term Loans and increased the aggregate principal amount available for borrowing under the U.S. Revolving Note from $100,000 to $250,000. New subsidiary borrowers and guarantors were added under the Amended Credit Agreement and related pledge and security agreement. The security agreement grants a security interest in substantially all of the personal property of 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-US subsidiaries). The Amended Credit Agreement restricts the amount of dividend payments the Company can make to shareholders. Note 6 – Debt – Continued The Amended Credit Agreement replaced the Company’s requirement to maintain a minimum Consolidated Fixed Charge Coverage Ratio with a minimum Consolidated Interest Coverage Ratio. The Company must also maintain a maximum Consolidated Leverage Ratio. Definitions for these financial ratios, and a description of modifications made to other covenants to which the Company and its subsidiaries are subject, are included in the Amended Credit Agreement. Under the Amended Credit Agreement, U.S. Dollar denominated loans bear interest at either a base rate (“Base Rate”) or Eurocurrency rate (“Eurocurrency Rate”), plus a margin (“Applicable Rate”). The Base Rate is equal to the highest of the Federal Funds Rate (0.30% at June 30, 2016) plus 0.50%, Bank of America’s prime rate (3.50% at June 30, 2016), or a one month Eurocurrency rate (0.00% at June 30, 2016) plus 1.00%. The Eurocurrency Rate for loans denominated in U.S. Dollars is equal to the London Interbank Offered Rate (0.47% at June 30, 2016). 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 from the initial period of March 17, 2016 through the fiscal quarter ending September 30, 2016 is 1.50% per annum for Eurocurrency Rate Loans and 0.50% per annum for Base Rate Loans. After the initial period, the Applicable Rate will vary 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 2.00%, respectively, for Eurocurrency Rate Loans and 0.25% and 1.00%, respectively, for Base Rate Loans. The Company also has two fixed interest rate loans with the German Investment Corporation (“DEG”), a subsidiary of KfW Banking Group, a Germany government-owned development bank: DEG China Loan The first DEG loan, a loan we used to fund capital investments in China (the “DEG China Loan”), is subject to semi-annual principal payments beginning March, 2015 and ending September, 2019. Under the terms of the DEG China Loan, the Company must maintain a minimum Debt-to-Equity Ratio, Current Ratio and Debt Service Coverage Ratio, as defined by the DEG China Loan agreement, based on the financial statements of Gentherm’s wholly owned subsidiary, Gentherm Automotive Systems (China) Limited. DEG Vietnam Loan The Company’s second fixed interest rate loan agreement with DEG was used to finance the construction and set up of the Vietnam production facility (“DEG Vietnam Loan”). The DEG Vietnam Loan is subject to semi-annual principal payments beginning November, 2017 and ending May, 2023. Under the terms of the DEG Vietnam Loan, the Company must maintain a minimum Current Ratio, Equity Ratio and Enhanced Equity Ratio, as defined by the DEG Vietnam Loan agreement, based on the financial statements of Gentherm’s wholly owned subsidiary, Gentherm Vietnam Co. Ltd. Note 6 – Debt – Continued The following table summarizes the Company’s debt at June 30, 2016 and at December 31, 2015.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 7 – Derivative Financial Instruments We are exposed to market risk from changes in foreign currency exchange rates, short-term interest rates and price fluctuations of certain material commodities such as copper. Market risks for changes in interest rates relate primarily to our debt obligations under our Amended Credit Agreement. Foreign currency exchange risks are attributable to sales to foreign customers and purchases from foreign suppliers not denominated in the location’s functional currency, foreign plant operations, intercompany indebtedness, intercompany investments and include exposures to the European 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 we hedge our exposure to foreign currency exchange risks is one year. We had foreign currency derivative contracts with a notional value of $37,503 and $0 outstanding as of June 30, 2016 and December 31, 2015, respectively. Note 7 – Derivative Financial Instruments – Continued The maximum length of time over which we hedge our exposure to price fluctuations in material commodities is two years. We had copper commodity swap contracts with a notional value of $2,850 and $4,885 outstanding at June 30, 2016 and December 31, 2015, respectively. We do not enter into derivative financial instruments for speculative or trading purposes. Our 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 balance sheet. When the underlying hedge transaction is realized, the gain or loss included in accumulated other comprehensive loss is recorded in earnings in the consolidated statement of income on the same line as the gain or loss on the hedged item attributable to the hedged risk. We record the ineffective portion of foreign currency hedging instruments, if any, to foreign currency gain (loss) in the consolidated statements of income. Though we continuously monitor the hedging program, derivative positions and hedging strategies, foreign currency forward exchange agreements have not always been designated as hedging instruments for accounting purposes. The Company uses an income approach to value derivative instruments, analyzing quoted market prices to calculate the forward values and then discounts such forward values to the present value using benchmark rates at commonly quoted intervals for the instrument’s full term. Information related to the recurring fair value measurement of derivative instruments in our consolidated condensed balance sheet as of June 30, 2016 is as follows: Asset Derivatives Liability Derivatives Net Asset/ Hedge Fair Value Balance Sheet Fair Balance Sheet Fair Foreign currency derivatives Cash flow hedge Level 2 Current assets $ 242 $ 242 Commodity derivatives Cash flow hedge Level 2 Current liabilities $ (320 ) $ (320 ) Information relating to the effect of derivative instruments on our consolidated condensed statements of income is as follows: Location Three Months Three Months Six Months Six Months Foreign currency derivatives Revaluation of derivatives $ — $ 81 $ — $ 6,278 Cost of sales 100 (192 ) 135 (320 ) Selling, general and administrative — 25 139 46 Other comprehensive income (1,049 ) (430 ) 244 (777 ) Foreign currency gain 71 82 149 289 Total foreign currency derivatives $ (878 ) $ (434 ) $ 667 $ 5,516 Currency related interest rate swap Revaluation of derivatives — (134 ) — (7,295 ) Commodity derivatives Cost of sales $ (142 ) $ — $ (353 ) $ — Other comprehensive income $ 109 $ (124 ) $ 405 $ (48 ) Total commodity derivatives $ (33 ) $ (124 ) $ 52 $ (48 ) We did not incur any hedge ineffectiveness during the three and six months ended June 30, 2016 and 2015.

Fair Value Measurement

Fair Value Measurement	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurement	Note 8 – Fair Value Measurement The Company bases fair value on a price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We have adopted a fair value hierarchy that prioritizes observable and unobservable inputs used 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. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and also considers counterparty credit risk in its assessment of fair value. Except for derivative instruments (see Note 7), pension liabilities, pension plan assets and a corporate owned life insurance policy, the Company has no material financial assets and liabilities that are carried at fair value at June 30, 2016 and December 31, 2015. The carrying amounts of financial instruments comprising cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to the relatively short maturity of such instruments. 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). The carrying values of the Company’s Amended Credit Agreement indebtedness for the periods ending June 30, 2016 and December 31, 2015, respectively, were not materially different than their estimated fair values because the interest rates on variable rate debt approximated rates currently available to the Company (see Note 6). Discount rates used to measure the fair value of Gentherm’s DEG Vietnam Loan and DEG China Loan are based on quoted swap rates. As of June 30, 2016, the carrying values of the DEG Vietnam Loan and DEG China Loan were $15,000 and $3,112, respectively, as compared to an estimated fair value of $15,400 and $3,200, respectively. As of December 31, 2015, the carrying value of the DEG Vietnam Loan and DEG China Loan were $15,000 and $3,497, respectively, as compared to an estimated fair value of $15,100 and $3,600, respectively. Certain Company assets are required to be recorded at fair value on a non-recurring basis when events and circumstances indicate that the carrying value may not be recoverable. As of June 30, 2016 and December 31, 2015, the Company did not realize any changes to the fair value of these assets due to the non-occurrence of events or circumstances that could negatively impact their recoverability.

Basis Of Presentation And New Accounting Pronouncements [Abstract]
Financial Instruments	Financial Instruments In January, 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” ASU 2016-01 requires equity investments not accounted for under the equity method of accounting or result in consolidation of an investee, that have readily determinable fair values to be measured at fair value with changes in the fair value recognized in net income. The update simplifies the impairment assessment for equity investments without readily determinable fair values by requiring assessment for impairment qualitatively, similar to the impairment assessment currently used for long-lived assets, goodwill and indefinite-lived intangible assets. The amendments in this update also change the disclosure requirements for financial instruments, including eliminating the requirement to disclose the method and significant assumptions used to estimate the fair value for financial instruments measured at amortized costs on the balance sheet. ASU 2016-01 is effective for fiscal years and interim periods beginning after December 15, 2017 and early adoption of the amendments in this update, in general, is not permitted. ASU 2016-01 is not expected to significantly impact the Company.
Leases	Leases In February, 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires lessees to recognize on their balance sheet a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. Payments to be made in optional periods should be included in the measurement of lease assets and liabilities if the lessee is reasonably certain it will exercise an option to extend the lease or not exercise an option to terminate the lease. While ASU 2016-02 continues to differentiate between finance or capital leases and operating leases, the principal change from current lease accounting guidance is that lease assets and liabilities arising from operating leases should be recognized on the balance sheet. ASU 2016-02 is effective for fiscal years and interim periods beginning after December 15, 2018. Early adoption of the amendments in this update is permitted. Lessees are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach which includes a number of practical expedients, including the ability to use hindsight in evaluating lessee options to extend or terminate a lease. An entity that elects to apply the practical expedients will be required to recognize a right-of-use asset and lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payment that were tracked and disclosed under previous GAAP. We are currently in the process of determining the impact the implementation of ASU 2016-02 will have on the Company’s financial statements.
Stock Compensation	Stock Compensation In March, 2016, the FASB issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Under the new standard, income tax benefits and deficiencies are to be recognized as income tax expense or benefit in the income statement and the tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity should also recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Excess tax benefits should be classified along with other income tax cash flows as an operating activity. In regards to forfeitures, the entity may make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. ASU 2016-09 is effective for fiscal years and interim periods beginning after December 15, 2016. Early adoption of the amendments in this update is permitted
Revenue from Contracts with Customers	Revenue from Contracts with Customers In May, 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 was developed to enable financial statement users to better understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The update’s core principal is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Companies are to use a five-step contract review model to ensure revenue gets recognized, measured and disclosed in accordance with this principle. In April, 2016, the FASB issued ASU 2016-10, “Identifying Performance Obligations and Licensing” to, amongst other things, reduce the cost and complexity it takes to identify performance obligations in a contract (step two in the five-step contract review model). As a result, entities are not required to assess whether promised goods or services are performance obligations if they are immaterial in the context of the contract. In June, 2015, the FASB issued ASU 2015-14, “Deferral of the Effective Date.” As a result of this update, ASU 2014-09 and ASU 2016-10 will be effective for fiscal years and interim periods beginning after December 15, 2017. The amendments in these updates will be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect recognized at the date of initial application. Gentherm has developed a plan to complete the five-step contract review process for all existing contracts with customers. We are currently in the process of determining the impact the implementation of ASU 2014-09 and ASU 2016-10 will have on the Company’s financial statements.
Inventory - Simplifying the Measurement of Inventory	Inventory – Simplifying the Measurement of Inventory In July, 2015, the FASB issued ASU 2015-11, “ Inventory (Topic 330) Simplifying the Measurement of Inventory.” The update requires that inventory measured using any method other than last-in, first-out (LIFO) or the retail inventory method shall be measured at the lower of cost and net realizable value. ASU 2015-11 is effective for fiscal years and interim periods beginning after December 15, 2016 and is not expected to significantly impact the Company.
Balance Sheet Classification of Deferred Taxes	Balance Sheet Classification of Deferred Taxes In November, 2015, the FASB issued ASU 2015-17, “ Income Taxes (Topic 740) Balance Sheet Classification of Deferred Taxes.” ASU 2015-17 no longer requires an entity to separate deferred income tax liabilities and assets into current and noncurrent amounts on the balance sheet. Instead, for each tax paying component and within each tax jurisdiction all deferred tax liabilities and assets, as well as related valuation allowance, shall be offset and presented as a single noncurrent amount. Entities will continue to not offset deferred tax liabilities and assets attributable to different tax-paying components of the entity or to different tax jurisdictions. ASU 2015-17 is effective for fiscal years and interim periods beginning after December 15, 2016, though earlier application is permitted. The update can be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented.
