Segment Reporting [Abstract]

Segment Reporting

Note 10 — Segment Reporting

Segment information is used by management for making operating decisions for the Company. Management evaluates the performance of the Company’s segments based primarily on operating income or loss (see Note 2).

The Company’s reportable segments are as follows:

1. Automotive — this segment represents the design, development, manufacturing and sales of automotive seat comfort systems, specialized automotive cable systems and certain automotive and non-automotive thermal convenience products.

2. Industrial — the combined operating results of GPT 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.

3. Reconciling Items — include corporate selling, general and administrative costs and acquisition transaction costs.

The tables below present segment information about the reported product revenues and operating income of the Company for years ended December 31, 2015, 2014 and 2013. With the exception of goodwill, asset information by segment is not reported since the Company does not manage assets at a segment level.
