Swift Transportation Co was formed on May 20, 2010. The Company is a multi-faceted transportation services company and operates the fleet of truckload equipment in North America. As of December 31, 2013, it operated a tractor fleet of approximately 18,000 units comprised of 12,800 tractors driven by company drivers and 5,200 owner-operator tractors, a fleet of 57,300 trailers, and 8,700 intermodal containers from 40 main terminals positioned near main freight centers and traffic lanes in the United States and Mexico. During 2013, its tractors covered 2.1 billion miles for shippers throughout North America. In its trucking operations, the Company mainly operates in short-to-medium-haul traffic lanes around its terminals or dedicated customer locations. The Company's four reportable operating segments consist of Truckload, Dedicated, Central Refrigerated and Intermodal. Its Truckload segment consists of one-way movements over irregular routes throughout the United States, Mexico and Canada. This service utilizes both company and owner-operator tractors with dry van, flatbed, as well as specialized trailing equipment. Its growing cross-border, Mexico truckload business includes service through Trans-Mex, the Company's wholly-owned subsidiary. Its Mexican operations mainly haul through commercial border crossings from Laredo, Texas westward to California. Through its Dedicated segment, the Company devote use of equipment and offer tailored solutions under long-term contracts. The Company's Dedicated operations use its terminal network, operating systems, and for-hire freight volumes to source backhaul opportunities to improve its asset utilization and reduce deadhead miles. In its Dedicated operations, the Company provide transportation professionals on-site at each customer's facilities and have a centralized team of transportation engineers to design transportation solutions to support private fleet conversions and/or develop optimal solutions for customers' transportation requirements. Its Central Refrigerated segment consists mainly of shipments for customers that require temperature-controlled trailers and represents the core operations of Central Refrigerated. These shipments include one-way movements over irregular routes, dedicated truck operations, as well as a small number of intermodal trailer on flat car, or TOFC, and third party logistics loads. Its Intermodal segment includes revenue generated by moving freight over the rail in its containers or other trailing equipment, combined with revenue for drayage to transport loads between the railheads and customer locations and requires lower tractor investment than general truckload service, making it one of the Company's less asset-intensive businesses. It offers these products to and from 59 active rail ramps located across North America. The Company's customers are corporations with extensive operations, geographically distributed locations, and diverse shipping needs. The Company competes with many truckload carriers and, to a lesser extent, with less-than-truckload carriers, or LTL, railroads, and third-party logistics, brokerage, freight forwarding, and other transportation companies. Its operations are regulated and licensed by various government agencies in the United States, Mexico, and Canada.
