2.      Segment Reporting

The service offerings provided by the Company relate to the transportation of truckload quantities of freight for customers in a variety of industries.  The services generate revenue, and to a great extent incur expenses, primarily on a per mile basis. The Company classifies its business into three operating and reportable segments:  our Trucking operating segment consisting of our Truckload and Dedicated Freight service offerings; our SCS operating segment consisting of our freight brokerage service offering; and our rail Intermodal operating segment.  SCS and Intermodal operating segments are intended to provide services that complement the Company’s Trucking services, primarily to existing customers of its Trucking operating segment.  Those complementary services consist of services such as freight brokerage, transportation scheduling, routing and mode selection.  A majority of the customers using our SCS and Intermodal services are also customers of our Trucking operating segment.

	Percent of Base Revenue
	Trucking			SCS			Intermodal
December 31, 2012		72.8	%		22.0	%		5.2	%
December 31, 2011		78.2	%		16.3	%		5.5	%

Except with respect to the relatively minor components of our operations that do not involve the use of our trucks, key operating statistics for all three segments include, for example, revenue per mile and miles per tractor per week.  While the operations of our SCS segment typically do not involve the use of our equipment and drivers, we nevertheless provide truckload freight services to our customers through arrangements with third party carriers who are subject to the same general regulatory environment and cost sensitivities imposed upon our Trucking operations.  Our Intermodal business does involve the use of our equipment as we utilize our trailers and leased containers to provide this service.  Accordingly, the operations of this segment are subject to the same general regulatory environment and cost sensitivities imposed upon our Trucking operations.

Assets are not allocated to our SCS segment as the significant majority of our SCS operations provide truckload freight services to our customers through arrangements with third party carriers who utilize their own equipment.  Assets are not allocated to our Intermodal segment as our Intermodal containers are utilized under operating leases with BNSF Railway, which are not capitalized.  To the extent our Intermodal operations require the use of Company-owned trailers, they are obtained from our Trucking segment on an as-needed basis.  Accordingly, we allocate all of our assets to our Trucking segment.  However, depreciation and amortization expense is allocated to our SCS segment based on the various assets specifically utilized to generate revenue.  All intercompany transactions between segments are consummated at rates similar to those negotiated with independent third parties.  All other expenses are allocated to our SCS segment based on headcount and specifically identifiable direct costs, as appropriate.
