Form 10-K for Fiscal Year Ended December 31, 2017 MD&A Results of Operations, page 34 1. In your discussion of automotive segment revenues, you disclose changes attributed to many product categories and other factors but it is not clear how the quantified amounts reconcile to the total change in automotive revenues. In addition, you attribute the increase in cost of sales in 2017 to increased sales volumes and other factors, but do not quantify the change attributed to increased sales volumes. As such, please consider expanding this section by: increasing the use of tables to present dollar and percentage changes in accounts, rather than including such information in narrative text form; Barry G.

Steele Comapany11, 2018 December NameGentherm Incorporated December 11, 2018 Page 2 Page 2 FirstName LastName using tables to list, quantify, and sum all of the material individual factors to which changes in accounts are attributable; refocusing the narrative text portion of the disclosure on analysis of the underlying business reasons for the individual factors in the tables above; ensuring that all material factors are quantified and analyzed; and quantifying the effects of changes in both price and volume on revenues and expense categories, where appropriate. Note 2 - Summary of Significant Accounting Policies Accrued Warranty Costs, page F-13 2. We note your reconciliation of the changes in the warranty liability includes reconciling items "warranty claims paid or retired" and "expense."

We note your disclosure in MD&A of changes in sales for certain product categories.

We note from page 29 that the $11.5 million impairment charge taken is comprised of $2.2 million in impairment loss recognized on held for sale assets, $6.2 million in impairment loss on goodwill, and $3.1 million in impairment loss recognized on other intangible assets, and that this relates to your classification of GPT and CSZ-IC as held for sale. We also note from your disclosure on page 28 that these entities, while meeting the qualifications to be considered held for sale, did not meet the qualifications to be considered as discontinued operations. Please tell us why you have classified these impairment charges as non-operating income in your statement of income. Refer to the guidance in Rule 5-03 of Regulation S-X.
