Notes to Financial Statements
Legal Matters and Contingencies [Text Block]	NOTE M: LITIGATION Other than the lawsuit discussed below, the Company is not a party to any pending legal proceeding which management believes to be material to the Consolidated financial statements of the Company. The Company maintains liability insurance against risks arising out of the normal course of its business. We are a defendant in a collective-action lawsuit which was filed on August 22, 2013, in the United States District Court for the Western District of Arkansas. The plaintiffs, who are current and former drivers and who worked for the Company during the period of August 22, 2010, through the date of the filing, allege claims for unpaid wages under the Fair Labor Standards Act and the Arkansas Minimum Wage Law. The complaint alleges that the Company failed to pay newly hired drivers minimum wage during orientation, training, and while traveling during normal business hours and that the Company failed to pay all drivers when working on assignment for more than 24 hours. The plaintiffs seek to enjoin the Company from continuing its current pay practices related to the allegations. They also seek actual damages, liquidated damages equal to accrual damages, court costs, and legal fees. During 2014, the Company reached a preliminary settlement with the plaintiffs in the amount of $3,950,000 and accordingly, reserved this amount, along with estimated settlement costs, in its 2014 consolidated financial statements. During the first quarter of 2015, the Company negotiated a reduction in the settlement amount to approximately $3,450,000. The settlement was approved by the court in January 2016, and we expect to make the settlement payment during the second quarter of 2016. Management has determined that losses under this claim will not be covered by existing insurance policies.
