Commitments and Contingencies Disclosure [Text Block] | 1 6 . Commitments and Contingencies We are committed to purchase $ 121.9 million of new revenue equipment in 2018, along with a land purchase obligation of $4.0 million in 2018 and operating lease obligation expenditures totaling $738,000 through 2021. We self-insure, in part, for losses relating to workers ’ compensation, auto liability, general liability, cargo and property damage claims, along with employees’ health insurance with varying risk retention levels. We maintain insurance coverage for per-incident and total losses in excess of these risk retention levels in amounts we consider adequate based upon historical experience and our ongoing review, and reserve currently for the estimated cost of the uninsured portion of pending claims. We are also involved in other legal actions that arise in the ordinary course of business. In the opinion of management, based upon present knowledge of the facts, it is remote that the ultimate outcome of any such legal actions will have a material adverse effect upon our long-term financial position or results of operations.
