Segment Information

The Company’s four reportable operating segments are Truckload, Dedicated, Central Refrigerated and Intermodal.

Truckload— The 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, and other specialized trailing equipment.

Dedicated— Through the Dedicated segment, the Company devotes use of equipment to specific customers and offers tailored solutions under long-term contracts. This dedicated segment utilizes refrigerated, dry van, flatbed and other specialized trailing equipment.

Central Refrigerated— This segment represents the core operations of Central and primarily consists of shipments for customers that require temperature-controlled trailers. These shipments include one-way movements over irregular routes, as well as dedicated truck operations.

Intermodal— The Intermodal segment includes revenue generated by moving freight over the rail in the Company's containers and other trailing equipment, combined with revenue for drayage to transport loads between the railheads and customer locations.

Non-reportable Segment— The other non-reportable segment includes the Company's logistics and freight brokerage services, as well as support services provided by its subsidiaries to customers and owner-operators, including repair and maintenance shop services, equipment leasing, and insurance. Intangible amortization related to the 2007 going-private transaction is also included in this other non-reportable segment.

Other Intersegment Transactions—Certain operating segments provide transportation and related services for other affiliates outside their reportable segment. Revenues for such services are based on negotiated rates, which we believe approximate fair value, and are reflected as revenues of the billing segment. These rates are adjusted from time to time based on market conditions. Such intersegment revenues and expenses are eliminated in our consolidated results.
