COMMITMENTS AND CONTINGENCIES Litigation. On June 17, 2014, a purported shareholder filed a derivative complaint against all of the then-current members of our board of directors and one of our former directors, as defendants, and our company, as nominal defendant, in the Court of Chancery of the State of Delaware. Through the complaint, the plaintiff is asserting, on behalf of our company, actions for breach of fiduciary duties and unjust enrichment in connection with prior determinations of our board of directors relating to nonexecutive director compensation. The plaintiff is seeking relief including disgorgement of payments made to the defendants, an award of unspecified damages and an award for attorneys fees and other costs. We and the defendants have filed a motion to dismiss the complaint and a supporting brief on which the Court has not yet ruled.

In the ordinary course of business, we are subject to actions for damages alleging personal injury under the general maritime laws of the United States, including the Jones Act, for alleged negligence. We report actions for personal injury to our insurance carriers and believe that the settlement or disposition of those claims will not have a material adverse effect on our consolidated financial position, results of operations or cash flows. Various other actions and claims are pending against us, most of which are covered by insurance. Although we cannot predict the ultimate outcome of these matters, we believe that our ultimate liability, if any, that may result from these other actions and claims will not materially affect our results of operations, cash flows or financial position.
