Chemours

Set forth below is a brief update of certain aspects of the separation of our Performance Chemicals business, now called The Chemours Company (“Chemours”). In addition, we are pleased to announce that, on April 21, 2015, Chemours filed an amendment to its Form 10 relating to the separation.

In the initial Form 10 filing for the separation of Chemours, we described the proposed governance structure originally selected for the new company. Your Board and management team developed this original governance structure, to be in place following the separation, based upon their extensive review and analysis of the treatment of governance-related provisions common for newly-public companies, including other then-recent spin-offs, and taking into account the advice of the Company’s legal advisors. The initial governance structure included, among other provisions, a classified board, an 80% threshold to amend the Chemours bylaws and certain charter provisions, a prohibition on stockholder action by written consent, a 35% threshold for stockholder-callable special meetings and a determination not to have Chemours opt out of Section 203 of the Delaware General Corporation Law.

Your Board prioritizes reviewing emerging best practices in corporate governance, as reflected in the governance structures that have been adopted at DuPont. Consistent with this approach, following the initial filing of the Form 10, the Board continued to assess the originally proposed Chemours governance provisions, including considering the diverse perspectives gathered in conversation with numerous stockholders on the subject and the treatment of governance at spin-off companies in other more recent situations. As the separation process proceeded, and based on such further evaluation, on March 3, 2015 your Board concluded to make certain changes to Chemours’ corporate governance, including revising the classified board structure and lowering the ownership threshold required for stockholders of Chemours to call special meetings. As a result, stockholders of Chemours will vote whether or not to approve the classified board structure at Chemours’ first annual meeting in 2016 and, if the classified board structure is not approved by a majority of the shares voted by its stockholders, the Chemours board will be declassified such that all directors would be up for annual election beginning with the 2017 Chemours annual meeting. Additionally, your Board determined to lower the ownership threshold required for Chemours’ stockholders to call special meetings to 25%. The Board determined not to modify any of the other Chemours governance provisions.

In connection with its ongoing proxy contest against DuPont, Trian Partners, L.P. and certain of its affiliates (“Trian”) has criticized the governance package at Chemours and, specifically, in its discussion with DuPont’s Chief Executive Officer, Ellen J. Kullman, and Lead Independent Director, Alexander M. Cutler, on March 11, 2015, Trian proposed, in addition to appointing two Trian nominees to our Board and two Trian nominees to the Chemours board, that DuPont make certain unspecified changes to the Chemours governance package. After careful consideration of the overall Trian proposal, your Board determined that it was not in the best interest of our stockholders and rejected the proposal as a whole.

On March 18, 2015, a putative class action lawsuit was filed in the Delaware Court of Chancery (The Vladimir Gusinsky Living Trust v. Ward, et al., C.A. 10811-VCG (Del. Ch.)) against the members of our Board, DuPont and Chemours, alleging, among other things, that the members of our Board violated their fiduciary duties in approving certain of the originally proposed Chemours governance provisions, including the classified board structure, the elimination of stockholders’ ability to act by written consent, the 35% threshold for stockholder-called special meetings, the 80% threshold to amend the foregoing, and the 90-day advance notice requirement for stockholder proposals or other nominations. The complaint was amended on March 20, 2015 to additionally allege that the members of our Board violated their fiduciary duties by failing to fully and fairly disclose such provisions in the Proxy Statement in connection with the Annual Meeting, by failing to specify each of the provisions Trian requested be changed and the reasons your Board refused to make such changes. The Amended Complaint seeks an injunction against the holding of the Annual Meeting and an award of attorneys’ fees, among other relief. DuPont believes these claims are entirely without merit.

Following its careful evaluation as described above, your Board believes that the proposed governance structure of Chemours, reflecting the changes described herein, is in the best interest of its stockholders.
