Segment Reporting [Abstract]

Segment Information

Segment Information

In connection with the organizational changes announced on February 14, 2013 that aligned our businesses along product lines, effective with the first quarter of 2013, our three prior geographic reportable segments have each been split into two product segments. Beginning with the first quarter of 2013, we are managed and organized along our two major product lines (emission control and ride control) and three geographic areas (North America; Europe, South America and India; and Asia Pacific), resulting in six operating segments (North America Clean Air, North America Ride Performance, Europe, South America and India Clean Air, Europe, South America and India Ride Performance, Asia Pacific Clean Air and Asia Pacific Ride Performance). Within each geographical area, each operating segment manufactures and distributes either ride control or emission control 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.
