Recognition of Revenue The Company generates revenues primarily from shipments executed by the Company’s Truckload and Brokerage operations. Those shipments are the Company’s performance obligations, arising under contracts we have entered into with customers. Under such contracts, revenue is recognized when obligations are satisfied, which occurs over time with the transit of shipments from origin to destination. This is appropriate as the customer simultaneously receives and consumes the benefits as the Company performs its obligation. Revenue is measured as the amount of consideration the Company expects to receive in exchange for providing services. The most significant judgment used in recognition of revenue is the determination of miles driven as the basis for determining the amount of revenue to be recognized for partially fulfilled obligations. Accessorial charges for fuel surcharge, loading and unloading, stop charges, and other immaterial charges are part of the consideration we receive for the single performance obligation of delivering shipments. Contracts entered into with our customers do not Certain incremental revenue-related costs associated with obtaining a contract are capitalized. The majority of revenue contracts with our customers have a duration of one not one $3.1 $1.0 September 30, 2018 Through the Company’s Brokerage operations, the Company outsources the transportation of the loads to third third The timing of revenue recognition, billings, cash collections, and allowance for doubtful accounts results in billed and unbilled receivables on the unaudited condensed consolidated balance sheet.

All significant intercompany transactions and accounts have been eliminated. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with Article 10 X 1933, Certain information and footnote disclosures have been condensed or omitted pursuant to such rules and regulations.

Revenue Recognition, Policy [Policy Text Block]	Recognition of Revenue The Company generates revenues primarily from shipments executed by the Company’s Truckload and Brokerage operations. Those shipments are the Company’s performance obligations, arising under contracts we have entered into with customers. Under such contracts, revenue is recognized when obligations are satisfied, which occurs over time with the transit of shipments from origin to destination. This is appropriate as the customer simultaneously receives and consumes the benefits as the Company performs its obligation. Revenue is measured as the amount of consideration the Company expects to receive in exchange for providing services. The most significant judgment used in recognition of revenue is the determination of miles driven as the basis for determining the amount of revenue to be recognized for partially fulfilled obligations. Accessorial charges for fuel surcharge, loading and unloading, stop charges, and other immaterial charges are part of the consideration we receive for the single performance obligation of delivering shipments. Contracts entered into with our customers do not Certain incremental revenue-related costs associated with obtaining a contract are capitalized. The majority of revenue contracts with our customers have a duration of one not one $3.1 $1.0 September 30, 2018 Through the Company’s Brokerage operations, the Company outsources the transportation of the loads to third third The timing of revenue recognition, billings, cash collections, and allowance for doubtful accounts results in billed and unbilled receivables on the unaudited condensed consolidated balance sheet.
