Proposed Merger with Dow Chemical [Abstract]
Proposed Merger with Dow Chemical	PLANNED MERGER WITH DOW On December 11, 2015, DuPont and The Dow Chemical Company (Dow) announced entry into an Agreement and Plan of Merger (the Merger Agreement), under which the companies will combine in an all-stock merger of equals subject to satisfaction of customary closing conditions, including receipt of regulatory approval. The combined company will be named DowDuPont Inc. (DowDuPont). Following the consummation of the merger, DuPont and Dow intend to pursue, subject to the receipt of approval by the board of directors of DowDuPont, the separation of the combined company’s agriculture business, specialty products business and material science business through a series of tax-efficient transactions (collectively, the Intended Business Separations). Subject to the terms and conditions of the Merger Agreement, each share of common stock, par value $0.30 per share, of DuPont (DuPont Common Stock) issued and outstanding immediately prior to the Effective Time, excluding any shares of DuPont Common Stock that are held in treasury, will be converted into the right to receive 1.2820 shares common stock, par value $0.01 per share, of DowDuPont (DowDuPont Common Stock), for each share of DuPont Common Stock with cash in lieu of any fractional share of DowDuPont. Each share of DuPont Preferred Stock-$4.50 Series and DuPont Preferred Stock-$3.50 Series, in each case issued and outstanding immediately prior to the Effective Time, shall remain issued and outstanding and be unaffected by the merger. Subject to the terms and conditions set forth in the Merger Agreement, at the Effective Time, each share of common stock, par value $2.50 per share, of Dow (the Dow Common Stock) issued and outstanding immediately prior to the Effective Time, excluding any shares of Dow Common Stock that are held in treasury, will be converted into the right to receive one share of DowDuPont Common Stock. On December 30, 2016, (the Dow Preferred Conversion Date) each share of Cumulative Convertible Perpetual Preferred Stock, Series A, par value $1.00 per share, of Dow (the Dow Preferred) issued and outstanding immediately prior thereto, converted to 24.2010 shares of Dow Common Stock. As a result, on the Dow Preferred Conversion Date, Dow issued 96,804,000 shares of Common Stock. Based on the aforementioned 1.2820 exchange ratio set forth in the Merger Agreement and the conversion of the Dow Preferred to Dow Common Stock, it is expected that DuPont common stockholders and Dow common stockholders will own approximately 48 percent and 52 percent, respectively, of the outstanding shares of DowDuPont Common Stock immediately following the Effective Time. Conditions to the Merger The completion of the merger is subject to the satisfaction or waiver of certain conditions, including (i) the receipt of certain domestic and foreign approvals under competition laws; (ii) DuPont and Dow reasonably determining that the merger does not constitute an acquisition of a 50 percent or greater interest in DuPont and Dow, respectively, under the principles of Section 355(e) of the Internal Revenue Code; (iii) the absence of governmental restraints or prohibitions preventing the consummation of the merger; and (iv) the approval of the shares of DowDuPont Common Stock to be issued in the merger for listing on the NYSE. The obligation of each of DuPont and Dow to consummate the merger is also conditioned on, among other things, the receipt of a tax opinion from the tax counsel as to the tax-free nature of the merger, and the truth and correctness of the representations and warranties made by the other party as of the closing date (subject to certain “materiality” and “material adverse effect” qualifiers).

DuPont's special meeting of stockholders was held on July 20, 2016, which resulted in a vote for adoption of the Merger Agreement and approval of related matters. Consummation of the merger is contingent on satisfaction of customary closing conditions, including the receipt of regulatory approval from the U.S., European Union, China, Brazil and Canada. Subject to satisfaction of these customary closing conditions, including the receipt of regulatory approvals, closing would be expected to occur in first half of 2017. Certain Other Terms of the Merger Agreement The Merger Agreement contains mutual customary representations and warranties made by each of DuPont and Dow, and also contains mutual customary pre-closing covenants, including covenants, among others, (i) to operate its businesses in the ordinary course consistent with past practice and to refrain from taking certain actions without the other party’s consent, (ii) not to solicit, initiate, knowingly encourage or knowingly take any other action designed to facilitate, and, subject to certain exceptions, not to participate in any discussions or negotiations, or cooperate in any way with respect to, any inquiries or the making of, any proposal of an alternative transaction, (iii) subject to certain exceptions, not to withdraw, qualify or modify the support of its Board of Directors for the Merger Agreement and the merger, as applicable, and (iv) to use their respective reasonable best efforts to obtain governmental, regulatory and third party approvals, including by agreeing to any required divestiture of assets or business.
