We purchase fuel and obtain tires and related services from Bauer Built, Incorporated, or BBI. Jerry M. Bauer, one of our directors, is the president and a stockholder of BBI. We paid BBI $1.2 million in 2005, $924,000 in 2004 and $805,000 in 2003 for fuel and tire services. In addition, we paid $2.0 million in 2005, $1.4 million in 2004 and $2.3 million in 2003 to tire manufacturers for tires that we purchased from the tire manufacturers but were provided by BBI. BBI received commissions from the tire manufacturers related to these purchases. Other than any benefit received from his ownership interest, Mr. Bauer receives no compensation or other benefits from our business with BBI.

During 2005 and 2004, we paid Durand Builders Service, Inc. $142,000 and $493,000, respectively, for various construction projects. Larry B. Hagness, one of our directors, is the president and owner of Durand Builders Service, Inc. Other than any benefit received from his ownership interest, Mr. Hagness receives no compensation or other benefits from these transactions.

MW Logistics, LLC, or MWL, our 45% owned affiliate, is a third-party provider of logistics services to the transportation industry. In 2005, 2004, and 2003, we received $21.1 million, $22.6 million and $13.8 million, respectively, of our revenue from transportation services arranged by MWL. We have applied the provisions of FASB Interpretation No. 46, “Consolidation of Variable Interest Entities,” as revised, to our investment in MWL effective March 31, 2004. As a result, the accounts of MWL are included in our Consolidated Balance Sheets as of December 31, 2005 and December 31, 2004, and in our Consolidated Statements of Operations beginning April 1, 2004. We accounted for our investment in MWL’s operating results using the equity method of accounting prior to April 1, 2004.

We believe that these transactions with related parties are on reasonable terms which, based upon market rates, are comparable to terms available from unaffiliated third parties.
