Business Combinations [Abstract] |
Business Combination Disclosure [Text Block] | COMMON CONTROL BUSINESS COMBINATIONS DAS Common Control Combination Based on an evaluation of the provisions of ASC 805 (Business Combinations), Corteva and DAS represented entities under common control, as both shared DowDuPont as their parent company. As a result, the assets, liabilities and operations of Corteva and DAS were combined at their historical carrying amounts, and periods prior to the Internal Reorganizations are adjusted as if Corteva and DAS had been combined since the Merger Effectiveness Time, when the entities were first under common control. Accordingly, in 2019, the accompanying Consolidated Financial Statements and Notes thereto were retrospectively revised to include the transferred net assets and results of operations of DAS beginning on September 1, 2017. Refer to Note 1 - Background and Basis of Presentation, for additional information on the common control combination. The following table provides supplemental results of EID and DAS, as previously reported, for the year ended December 31, 2018:
