(a)

Segment net sales include intersegment sales in our Engine Management and Temperature Control segments.

(b)

Other consists of the elimination of intersegment sales from our Engine Management and Temperature Control segments as well as sales from our Canadian business unit that does not meet the criteria of a reportable operating segment. Intersegment compressor sales for the three months ended March 31, 2019 and 2018 exceeded third party sales from our Canadian business unit.

Geographic Area

We sell our line of products primarily in the United States, with additional sales in Canada, Mexico, Europe, Asia and Latin America. Sales are attributed to countries based upon the location of the customer. Our sales are substantially denominated in U.S. dollars.

Major Product Group

The Engine Management segment of the Company principally generates revenue from the sale of automotive engine replacement parts including ignition, emission control, fuel and safety related system products, and wire and cable parts. The Temperature Control segment of the Company principally generates revenue from the sale of automotive temperature control systems replacement parts including air conditioning compressors and other climate control parts.

Major Sales Channel

In the aftermarket channel, we sell our products to warehouse distributors and retailers. Our customers buy directly from us and sell directly to jobber stores, professional technicians and to “do-it-yourselfers” who perform automotive repairs on their personal vehicles. In the Original Equipment (“OE”) and Original Equipment Service (“OES”) channel, we sell our products to original equipment manufacturers who redistribute our products within their distribution network, independent dealerships and service dealer technicians. Lastly, in the Export channel, our domestic entities sell to customers outside the United States.
