| Segment Reporting                | Segment ReportingThe following is a description of our four reporting segments:•Our North America Truck segment manufactures and distributes Class 4 through 8 trucks, buses, and military vehicles under the International and IC Bus ("IC") brands, along with production of engines under the MaxxForce brand name, in the North America markets that include sales in the U.S., Canada, and Mexico. In an effort to strengthen and maintain our dealer network, this segment occasionally acquires and operates dealer locations for the purpose of transitioning ownership.•Our North America Parts segment provides customers with proprietary products needed to support the International commercial and military truck, IC Bus, MaxxForce engine lines, as well as our other product lines. Our North America Parts segment also provides a wide selection of other standard truck, trailer, and engine aftermarket parts. At July 31, 2014, this segment operated eleven regional parts distribution centers that provide 24-hour availability and shipment. Also included in the North America Parts segment are the operating results of BDP, which manages the sourcing, merchandising, and distribution of certain service parts we sell to Ford in North America.•Our Global Operations segment includes businesses that derive their revenue from outside our core North America markets and primarily consists of the IIAA (formerly MWM) engine and truck operations in Brazil and our export truck and parts businesses.
