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 and other consumer and industrial temperature control needs. Our 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. 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 will be 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 March 31, 2016. The deferred charge is included in other non-current assets as of March 31, 2016. Subsequent Events We have evaluated subsequent events through the date that our consolidated condensed financial statements are issued. 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 for approximately $73,000, net of cash acquired. Based in Cincinnati, Ohio, CSZ manufactures both high quality patient temperature systems for the health care industry and custom environmental text chambers used by a wide range of industrial manufacturing companies for product testing. CSZ’s 2015 revenues were approximately $63,000. For the three months ended March 31, 2016, CSZ’s revenues were approximately $16,000.
