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.  Unless the context otherwise requires, the terms “Company”, “we”, “us” and “our” used herein refer to Gentherm Incorporated and its consolidated subsidiaries. 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 climatic comfort product opportunities in both automotive and other markets.  We concentrate our research on the development of new technologies that will improve overall product effectiveness and 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.
	Buyout of Joint Venture Partner
	On February 12, 2014 we acquired all of the previously unowned shares in our North American electronics manufacturing joint venture which had previously been accounted for under the equity method.  The purchase was accounted for using the acquisition method and resulted in a gain of $785.
	Global Thermoelectric
	On April 1, 2014, we acquired all of the stock of privately-held Global Thermoelectric Inc. (“GTE”), in an all-cash transaction.  GTE is the global market leader and developer of thermoelectric generators.  GTE’s world headquarters and manufacturing operations are located in Alberta, Canada. See Note 3, “Global Thermoelectric Acquisition” for additional information regarding GTE.
	Subsequent Events
	We have evaluated subsequent events through the date that our consolidated 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	'
	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 the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. 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, 2013 was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. Operating results for the three and six month periods ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. 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, 2013.
	Revenue from Contracts with Customers
	In May 2014, the Financial Accounting Standards Board (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 principal.
	ASU 2014-09 is effective for fiscal years and interim periods beginning after December 15, 2016.  The amendments in this update should be applied retrospectively either to each prior reporting period presented or to disclose the cumulative effect recognized at the date of initial application.  Gentherm is developing a plan to complete the five-step contract review process for all existing contracts with customers.  We are still in the process of determining the impact the implementation of ASU 2014-09 will have on the Company’s financial statements.
	Note 2 – Basis of Presentation and New Accounting Pronouncements – Continued
	Share-Based Payments
	In June 2014, the FASB issued ASU 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.”  This update provides guidance on the treatment of awards containing performance targets that affect vesting and that could be achieved after an employee’s requisite service period.  The update states that these types of performance targets should be treated as a performance condition and, therefore, not reflected in estimating the fair value of the award at the grant date.  Compensation cost shall be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service period has been rendered.  Should the probability of achievement occur before the end of the requisite service period, the remaining unrecognized compensation cost shall be recognized prospectively over the remaining requisite service period.  The total compensation cost reflects the number of awards expected to vest and shall be adjusted to reflect when those awards ultimately vest.
	ASU 2014-12 is effective for fiscal years and interim periods beginning after December 15, 2015.   Gentherm has not assigned specific performance targets to share-based awards that are currently outstanding and, therefore, it is unlikely this update will materially impact the Company’s financial statements.

Global Thermoelectric Acquisition	'
	Note 3 – Global Thermoelectric Acquisition
	GTE develops, manufactures and sells thermoelectric and non-thermoelectric systems and related products.  The principal application for these technologies include natural gas well and pipeline protection systems and remote power generation for instrumentation, automation and telecommunication systems.
	Results of operations for GTE are included in the Company’s consolidated condensed financial statements beginning April 1, 2014.  GTE contributed $8,174 in product revenues and an operating loss of $42 for the three and six month periods ended June 30, 2014.
	Purchase Price Allocation
	The purchase price of approximately $34,163, net of cash acquired of $3,061, has been allocated to the values of assets acquired and liabilities assumed as of April 1, 2014.  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 will be completed 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, 2014.  The preliminary allocation as of April 1, 2014 was as follows:
	Accounts receivable	$	10,200

	Supplemental Pro Forma Information
	The unaudited pro forma combined historical results for the amounts of GTE’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, 2014 or January 1, 2013 are as follows:
		Three Months Ended				Six Months Ended

	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 necessarily indicative of future operating results.
	Goodwill
	We recorded goodwill of approximately $6,601 arising from the acquisition. It is estimated that none of the goodwill recognized will be deductible for income tax purposes.
	Intangible Assets
	In conjunction with the acquisition, intangible assets of $9,871 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 (balances are higher as of June 30, 2014 than as of April 1, 2014, the acquisition date, due to fluctuations in foreign currency exchange rates totaling $362):

Earnings per Share	'
	Note 4 – Earnings per Share
	Basic earnings per common 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 shares 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 purchased from the conversion of Common Stock equivalents.
	The following summarizes the common shares included in the basic and diluted shares, as disclosed on the face of the consolidated condensed statements of income:
		Three Months				Six Months
		Ended June 30,				Ended June 30,
		2014		2013		2014		2013

	The accompanying table represents Common Stock issuable upon the exercise of certain stock options and Series C Convertible Preferred Stock that have been excluded from the diluted earnings calculation because the effect of their inclusion would be anti-dilutive. There were no issued and outstanding Series C Convertible Preferred Stock during the three and six months ended June 30, 2014.

Segment Reporting	'
	Note 5 – Segment Reporting
	As part of the initiative to integrate the operations of historical Gentherm and W.E.T. Automotive Systems AG (“W.E.T.”) (now known as Gentherm GmbH), changes were made during the first quarter of 2014 to Gentherm’s structure of internal organization.  Gentherm no longer treats the operations of historical Gentherm and W.E.T. as separate segments.
	As discussed in Note 3, Gentherm acquired GTE on April 1, 2014.  The acquisition enhances key elements of the Company’s business strategy by expanding the breadth of products derived from core thermal technologies as well as the markets in which they are applied.   The chief operating decision maker evaluates Company resources and analyzes the operational performance of GTE separate from the automotive segment.  The Company evaluated the significance of the GTE acquisition and determined it did not meet the thresholds to be presented in a separate and distinct segment.  Therefore, the combined results of GTE and the advanced research and product development division (formally known as the Advanced Technology segment) represent a reporting segment for the Company.  These changes to the internal organization structure are reflected in the financial information used by our chief operating decision maker to allocate Company resources and assess operating performance.
	Corporate reconciling items include certain selling, general and administrative costs previously reflected in the W.E.T. segment.
	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  – the aggregated operating results from Gentherm’s three geographic operating segments: North America, Europe and Asia.
	—	Industrial – the combined operating results of GTE and Gentherm’s advanced research and development division.  Advanced research and development includes efforts focused on improving the efficiency of thermoelectric devices and advanced heating wire technology as well as other applications. The segment includes governmental sponsored research projects, including those sponsored by the U.S. Department of Energy, the German Ministry of Economics and Technology and the European Union.
	—	Reconciling Items – include corporate selling, general and administrative costs and acquisition transaction costs.
	The following table presents segment information about the reported product revenues and operating income of the Company for the three and six month periods ended June 30, 2014 and 2013.

Debt	'
	Note 6 – Debt
	We have outstanding credit agreements with a syndicate of banks led by Bank of America (the “US Bank of America credit facility” and the “W.E.T. Bank of America credit facility”).
	The US Bank of America credit facility includes two term notes (referred to as the “US Term Note and Europe Term Note”) and a revolving line of credit note (“US Revolving Note”). The W.E.T. Bank of America credit facility includes a term note (“W.E.T. Term Note”) and a revolving line of credit note (“W.E.T. Revolving Note”).
	Note 6 – Debt – Continued
	In March 2014, Gentherm borrowed $13,455 against the US Revolving Note to partially finance the purchase of GTE on April 1, 2014.  No amounts have been borrowed under W.E.T. Revolving Note as of June 30, 2014.   As of June 30, 2014, $16,545 and €20,000 were available under the US Revolving Note and the WET Revolving Note, respectively. See Note 3, “Global Thermoelectric Acquisition” for additional information regarding GTE.
	Principal outstanding under these credit facilities is due and payable in full on March 30, 2016. Interest is payable quarterly. The Company must maintain a minimum Consolidated Fixed Charge Coverage Ratio and a maximum Leverage Ratio, as defined by the Bank of America credit agreement. The loans are secured by all of the Company’s assets.
	The Company has a fixed interest rate loan with the German Investment Corporation, a subsidiary of KfW banking group, a German government-owned development bank (“DEG Loan”). The DEG Loan is subject to semi-annual principal payments beginning March, 2015 and ending September, 2019. Under the terms of the DEG Loan, the Company must maintain a minimum Debt-to-Equity Ratio, Current Ratio and Debt Service Coverage Ratio based on the financial statements of W.E.T. Automotive Systems (China) Limited, as defined by the DEG Loan agreement.
	The Company has a capital lease agreement for an enterprise resource planning system.  Under the terms of the lease, the Company must maintain certain financial covenants.  Ownership of the system will be transferred to the Company at the end of the agreement.

Derivative Financial Instruments	'
	Note 7 – Derivative Financial Instruments
	We are exposed to market risk from changes in foreign currency exchange rates and short term interest rates. Market risks for changes in interest rates relate primarily to our debt obligations under our Bank of America credit facilities. 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 and include exposures to the European Euro, Mexican Peso, Canadian Dollar, Hungarian Forint, Ukraine Hryvnia and Korean Won.
	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. 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. We record the ineffective portion of hedging instruments, if any, to other income (expense) in the consolidated condensed 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.
	Note 7 – Derivative Financial Instruments – Continued
	The Company uses a market approach to value derivative instruments, analyzing observable benchmark rates at commonly quoted intervals for the instrument’s full term.   For information about notional values and expected maturities of derivative instruments, see Part I, Item 3. “Quantitative and Qualitative Disclosures About Market Risk” included in this Report.

Fair Value Measurement	'
	Note 8 – Fair Value Measurement
	The Company bases fair value on the 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: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.
	Level 3: Unobservable inputs 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, pension liabilities and pension plan assets, the Company has no financial assets and liabilities that are carried at fair value at June 30, 2014 and 2013. The carrying amounts of financial instruments comprising cash and cash equivalents and accounts receivable approximate their fair values due to their short-term nature. The carrying value of the Company’s long-term debt approximates its fair value because interest charged on the loan balance is variable. See Note 7, “Derivative Financial Instruments” for information regarding the fair value of derivative instruments and hedging activities.
	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, 2014 and 2013, the Company did not realize any changes to the fair value of these assets due to events that negatively impacted their recoverability.

Revenue from Contracts with Customers	'
	Revenue from Contracts with Customers
	In May 2014, the Financial Accounting Standards Board (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 principal.
	ASU 2014-09 is effective for fiscal years and interim periods beginning after December 15, 2016.  The amendments in this update should be applied retrospectively either to each prior reporting period presented or to disclose the cumulative effect recognized at the date of initial application.  Gentherm is developing a plan to complete the five-step contract review process for all existing contracts with customers.  We are still in the process of determining the impact the implementation of ASU 2014-09 will have on the Company’s financial statements.
Share-Based Payments	'
	Share-Based Payments
	In June 2014, the FASB issued ASU 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.”  This update provides guidance on the treatment of awards containing performance targets that affect vesting and that could be achieved after an employee’s requisite service period.  The update states that these types of performance targets should be treated as a performance condition and, therefore, not reflected in estimating the fair value of the award at the grant date.  Compensation cost shall be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service period has been rendered.  Should the probability of achievement occur before the end of the requisite service period, the remaining unrecognized compensation cost shall be recognized prospectively over the remaining requisite service period.  The total compensation cost reflects the number of awards expected to vest and shall be adjusted to reflect when those awards ultimately vest.
	ASU 2014-12 is effective for fiscal years and interim periods beginning after December 15, 2015.   Gentherm has not assigned specific performance targets to share-based awards that are currently outstanding and, therefore, it is unlikely this update will materially impact the Company’s financial statements.
