MARTEN TRANSPORT LTD

We are involved in ordinary routine litigation incidental to our operations. These lawsuits primarily involve claims for workers’ compensation, wage and hour law violations, personal injury or property damage incurred in the transportation of freight. Based on our present knowledge of the facts and, in certain cases, advice of outside counsel, management believes the resolution of open claims and pending litigation, taking into account existing reserves, is not likely or probable to have a materially adverse effect on our consolidated financial statements; however, the final disposition of these matters and the impact of such final dispositions cannot be determined at this time. As such, future liability claims or adverse developments in existing claims could have a materially adverse effect on our consolidated financial statements. Information is provided below for such existing claims, with the eventual outcome for each claim dependent on the results of additional discovery, future court rulings, and potentially trial and appeal. Marten intends to continue to vigorously defend itself in each matter.
