Segment Reporting [Abstract]

Segment Information

Segment Information

In connection with the reportable segment changes announced on February 7, 2017, our Clean Air and Ride Performance product lines in India, which have been reported as part of Europe, South America and India segments, will now be reported with their respective product lines in the Asia Pacific segments. Beginning with the first quarter of 2017, we are organized and manage our business along our two major product lines (clean air and ride performance) and three geographic areas (North America; Europe and South America; Asia Pacific), resulting in six operating segments (North America Clean Air, North America Ride Performance, Europe and South America Clean Air, Europe and South America Ride Performance, Asia Pacific Clean Air and Asia Pacific Ride Performance). Within each geographical area, each operating segment manufactures and distributes either clean air or ride performance products primarily for the original equipment and aftermarket industries. Each of the six operating segments constitutes a reportable segment. Costs related to other business activities, primarily corporate headquarter functions, are disclosed separately from the six operating segments as "Other." We evaluate segment performance based primarily on earnings before interest expense, income taxes, and noncontrolling interests. Products are transferred between segments and geographic areas on a basis intended to reflect as nearly as possible the “market value” of the products. Prior period segment information has been revised to reflect our new reporting segments.
