On April 28, 2015, a purported shareholder derivative petition was filed against all of our current directors, our current chief financial officer, and our past chief executive officer and past vice president of African affairs in the Delaware Court of Chancery. The petition alleges breaches of their fiduciary duties of loyalty and good faith in connection with potential violations by us of the FCPA. The plaintiff seeks an unspecified amount of damages against these persons and does not request any damages from us.
