Summary of Significant Accounting Policies

Interim Financial Statements

The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair statement of the results for interim periods have been included. Results for interim periods should not be considered indicative of results for a full year. These interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto contained in the company’s Annual Report on Form 10-K for the year ended December 31, 2016, collectively referred to as the “2016 Annual Report”. The interim Consolidated Financial Statements include the accounts of the company and all of its subsidiaries in which a controlling interest is maintained.

Principles of Consolidation and Basis of Presentation

DowDuPont Inc. ("DowDuPont") was formed on December 9, 2015 to effect an all-stock, merger of equals strategic combination between The Dow Chemical Company ("Dow") and E. I. du Pont de Nemours and Company ("DuPont") (the "Merger Transaction"). On August 31, 2017 at 11:59 pm ET, (the "Merger Effectiveness Time") pursuant to the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017 (the "Merger Agreement"), Dow and DuPont each merged with wholly owned subsidiaries of DowDuPont ("Mergers") and, as a result of the Mergers, Dow and DuPont became subsidiaries of DowDuPont (collectively, the "Merger"). Prior to the Merger, DowDuPont did not conduct any business activities other than those required for its formation and matters contemplated by the Merger Agreement. DowDuPont intends 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).

For purposes of DowDuPont's financial statement presentation, Dow was determined to be the accounting acquirer in the Merger and DuPont's assets and liabilities are reflected at fair value as of the Merger Effectiveness Time. In connection with the Merger and the related accounting determination, DuPont has elected to apply push-down accounting and reflect in its financial statements, the fair value of its assets and liabilities. DuPont's interim Consolidated Financial Statements for periods following the close of the Merger are labeled “Successor” and reflect DowDuPont’s basis in the fair values of the assets and liabilities of DuPont. All periods prior to the closing of the Merger reflect the historical accounting basis in DuPont's assets and liabilities and are labeled “Predecessor.” The interim Consolidated Financial Statements and Footnotes include a black line division between the columns titled "Predecessor" and "Successor" to signify that the amounts shown for the periods prior to and following the Merger are not comparable. See Note 3 for additional information on the Merger.

Transactions between DowDuPont, DuPont, Dow and their affiliates and other associated companies are reflected in the Successor consolidated financial statements and disclosed as related party transactions when material. Related party transactions with DowDuPont and Dow and their affiliates were not material as of September 30, 2017 and for the period September 1 through September 30, 2017.

As a condition of the regulatory approval for the Merger Transaction, the company is required to divest certain assets related to its Crop Protection business and research and development ("R&D") organization, specifically the company’s Cereal Broadleaf Herbicides and Chewing Insecticides portfolios, including Rynaxypyr^®, Cyazypyr^® and Indoxacarb as well as the Crop Protection R&D pipeline and organization, excluding seed treatment, nematicides, and late-stage R&D programs. On March 31, 2017, the company entered into a definitive agreement (the "FMC Transaction Agreement") with FMC Corporation ("FMC"). Under the FMC Transaction Agreement, FMC will acquire the Crop Protection business and R&D assets that DuPont is required to divest in order to obtain European Commission ("EC") approval of the Merger Transaction as described above, (the "Divested Ag Business") and DuPont has agreed to acquire certain assets relating to FMC’s Health and Nutrition segment, excluding its Omega-3 products, (the "Acquired H&N Business") (collectively, the "FMC Transactions"). This transaction closed on November 1; see Note 4 for further information regarding the closing.

The assets and liabilities related to the Divested Ag Business at September 30, 2017 are presented as held for sale in the interim Consolidated Balance Sheet. The sale of the Divested Ag Business meets the criteria for discontinued operations and as such, earnings are included within income from discontinued operations after income taxes for all periods presented. The sum of the individual earnings per share amounts from continuing operations and discontinued operations may not equal the total company earnings per share amounts due to rounding. The cash flows and comprehensive income related to the Divested Ag Business have not been segregated and are included in the interim Condensed Consolidated Statements of Cash Flows and Consolidated Statements of Comprehensive Income, respectively, for all periods presented. Amounts related to the Divested Ag Business are consistently included or excluded from the Notes to the interim Consolidated Financial Statements based on the respective financial statement line item. See Note 4 for further information.

On July 1, 2015, the company completed the separation of its Performance Chemicals segment through the spin-off of all of the issued and outstanding stock of The Chemours Company ("Chemours"). In accordance with GAAP, the results of operations of the Performance Chemicals segment are presented as discontinued operations and, as such, have been excluded from continuing operations for all periods presented. The sum of the individual earnings per share amounts from continuing operations and discontinued operations may not equal the total company earnings per share amounts due to rounding.

Certain reclassifications of prior year's data have been made to conform to current year's presentation. As described in Note 2, effective January 1, 2017, the company adopted the Financial Accounting Standards Board (“FASB”) Accounting Standards Update ("ASU") No. 2016-09, Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting. In conjunction with the adoption of this ASU, the company retrospectively reclassified cash flows related to income tax impacts associated with employee share-based payments in the interim Condensed Consolidated Statements of Cash Flows, as described in Note 2.

•

Use of Estimates

In connection with the Merger, DowDuPont has performed a preliminary allocation of the total consideration exchanged for the DuPont assets and liabilities it acquired using preliminary estimates. The estimates are subject to change as discussed in Note 3.

Segments

Prior to the Merger, DuPont's reportable segments included Agriculture, Electronics & Communication, Industrial Biosciences, Nutrition & Health, Performance Materials, Protection Solutions and Other. Effective with the Merger, DuPont’s business activities are components of its parent company’s business operations. DuPont’s business activities, including the assessment of performance and allocation of resources, will be reviewed and managed by DowDuPont. Information used by the chief operating decision maker of DuPont relates to the company in its entirety. Accordingly, there are no separate reportable business segments for DuPont under Accounting Standards Codification ("ASC") Topic 280 “Segment Reporting” and DuPont's business results are reported in this Form 10-Q as a single operating segment.
