Revenue from Contract with Customer [Abstract] |
Revenue from Contract with Customer [Text Block] | Revenue Recognition The Company generates revenue from transportation services under contracts with customers, generally on a rate per mile or per shipment, based on origin and destination of the shipment. The Company’s performance obligation arises when it accepts a shipment order to transport a customer’s freight and is satisfied upon delivery of the shipment. The transaction price may be defined in a transportation services agreement or negotiated with the customer prior to accepting the shipment order. A customer may submit several shipment orders for transportation services at various times throughout a service agreement term, but each shipment represents a distinct service that is a separately identified performance obligation. The Company often provides additional accessorial and other services as part of the shipment (including but not limited to loading/unloading, stops in transit, and tractor and trailer detention) which are not distinct or are not material in the context of the contract; therefore the revenue for these services is recognized with the freight transaction price. Fuel surcharge revenue consists of additional fees earned by the Company in connection with the performance of line haul services to partially or completely offset the cost of fuel. The Company also provided non-asset based brokerage services recorded during the three months ended March 31, 2017 before these services were ended in late 2017. Revenues are recognized over time as control of the promised services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those services. Revenue is estimated for multiple-stop loads based on miles run and estimated for single stop loads based on transit time, as the customer simultaneously receives and consumes the benefit provided. Revenue associated with loads delivered but not billed as of the end of an accounting period are also estimated as part of revenue for that period. Revenue recognition methods described align with the recognition of our associated expenses in the statement of comprehensive income. Total revenues recorded were $156.7 million and $129.9 million for the three months ended March 31, 2018 and 2017, respectively. Fuel surcharge revenues were $21.5 million and $14.9 million for the three months ended March 31, 2018 and 2017, respectively. Accessorial and other revenues recorded in the consolidated statements of comprehensive income collectively represented $4.3 million and $4.9 million for the three months ended March 31, 2018 and 2017, respectively.
