As a result of the sale of Constellium N.V.'s Class A ordinary shares held by Rio Tinto on November 14, 2013, Rio Tinto's right to designate one director to the company's board of directors terminated under the Amended and Restated Shareholders Agreement between the company and certain of its shareholders. Accordingly, Bret K. Clayton, who was appointed to serve as a director by Rio Tinto, has resigned as a non-executive director of the company's board, effective January 20, 2014.
