[1] The CODM does not receive fuel surcharge revenue and fuel expense individually, but is provided with fuel expense less fuel surcharge revenue (other than the fuel surcharge revenue we reimburse to independent contractors and other third parties which is included in purchased transportation), which we refer to as net fuel expense. The CODM uses net fuel expense to measure the effectiveness of our fuel surcharge program.
