Notes to Financial Statements
Revenue from Contract with Customer [Text Block]	NOTE C: REVENUE RECOGNITION The Company has a single performance obligation, to transport our customer’s freight from a specified origin to a specified destination. The Company has the discretion to choose to self-transport or to arrange for alternate transportation to fulfill the performance obligation. Where the Company decides to self-transport the freight, the Company classifies the service as truckload services, and where the Company arranges for alternate transportation of the freight, the Company classifies the service as brokerage and logistics services. In either case, the Company is paid a rate to transport freight from its origin location to a specified destination. Because the primary factors influencing revenue recognition, including performance obligation, customer base, and timing of revenue recognition, are the same for both of its service categories, the Company utilizes the same revenue recognition method throughout its operations. Company revenue is generated from freight transportation services performed utilizing heavy truck trailer combinations. While various ownership arrangements may third not In fulfilling the Company’s obligation to transport freight from a specified origin to a specified destination, control of freight is transferred to us at the point it has been loaded into the driver’s trailer, the doors are sealed and the driver has signed a bill of lading, which is the basic transportation agreement that establishes the nature, quantity and condition of the freight loaded, the responsibility for invoice payment and the pickup and delivery locations. Our revenue is generated, and our customer receives benefit, as the freight progresses towards delivery locations. In the event our customer cancels the shipment at some point prior to the final delivery location and re-consigns the shipment to an alternate delivery location, we are entitled to receive payment for services performed for the partial shipment. Shipments are generally conducted over a relatively short time span, generally one three one Freight Revenue – revenue generated by the performance of the freight transportation service, including any accessorial service, provided to customers. Fuel Surcharge Revenue – revenue designed to adjust freight revenue rates to an agreed-upon base cost for diesel fuel. Diesel fuel prices can fluctuate widely during the term of a contract with a customer. At the point that freight revenue rates are negotiated with customers, a sliding scale is agreed upon that approximately adjusts diesel fuel costs to an agreed-upon base amount. In general, as fuel prices increase, revenue from fuel surcharge increases, so that diesel fuel cost is adjusted to the approximate base amount agreed upon. Revenue is recognized over time as the freight progresses towards its destination and the transportation service obligation is fulfilled. For loads picked up during the reporting period, but delivered in a subsequent reporting period, revenue is allocated to each period based on the transit time in each period as a percentage of total transit time. There are no

The Company follows the guidance for financial assets and liabilities measured on a recurring basis. This guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date and also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

For long-term debt other than the lines of credit, the fair values are estimated using discounted cash flow analyses, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements.
