Income Statement, Balance Sheet and Additional Disclosures by Disposal Groups, Including Discontinued Operations [Line Items]

Intended Business Separations [Policy Text Block]

Subsequent to the Merger, Historical Dow and Historical EID engaged in a series of internal reorganization and realignment steps to realign their businesses into three subgroups: agriculture, materials science and specialty products through a series of tax-efficient transactions (collectively, the "Business Separations”). Effective as of 5:00 pm ET on April 1, 2019, DowDuPont completed the previously announced separation of its materials science business into a separate and independent public company by way of a distribution of Dow Inc. (“Dow”) through a pro rata dividend in-kind of all of the then-issued and outstanding shares of Dow’s common stock, par value $0.01 per share, to holders of DowDuPont's common stock (the “DowDuPont Common Stock”), as of the close of business on March 21, 2019 (the “Dow Distribution” and together with the Corteva Distribution, the “Distributions”).

Prior to the Dow Distribution, Historical Dow conveyed or transferred the assets and liabilities aligned with Historical Dow’s agriculture business to separate legal entities (“Dow Ag Entities”) and the assets and liabilities associated with its specialty products business to separate legal entities (the “Dow SP Entities”). On April 1, 2019, Dow Ag Entities and the Dow SP Entities were transferred and conveyed to DowDuPont.

In furtherance of the Business Separations, EID engaged in a series of internal reorganization and realignment steps (the “Internal Reorganization” and the "Business Realignment," respectively) to realign its businesses into three subgroups: agriculture, materials science and specialty products. As part of the Internal Reorganization:

• the assets and liabilities aligned with EID’s materials science business, including EID’s ethylene and ethylene copolymers business, excluding its ethylene acrylic elastomers business, (“EID ECP”) were transferred or conveyed to separate legal entities (the “Materials Science Entities”) that were ultimately conveyed by DowDuPont to Dow;

• the assets and liabilities aligned with the EID’s specialty products business were transferred or conveyed to separate legal entities (“EID Specialty Products Entities”);

• on April 1, 2019, EID transferred and conveyed its Materials Science Entities to Dow;

• on May 1, 2019, EID distributed its Specialty Products Entities to DowDuPont;

• on May 2, 2019, DowDuPont conveyed Dow Ag Entities to EID and in connection with the foregoing, EID issued additional shares of its Common Stock to DowDuPont; and

• on May 31, 2019, DowDuPont contributed EID to Corteva, Inc.

On May 6, 2019, the Board of Directors of DowDuPont approved the distribution of all the then-issued and outstanding shares of common stock of Corteva, Inc., a wholly-owned subsidiary of DowDuPont, to DowDuPont stockholders. On June 1, 2019, DowDuPont completed the Separation. Each DowDuPont stockholder received one share of Corteva common stock for every three shares of DowDuPont common stock held at the close of business on May 24, 2019, the record date of distribution. Corteva, Inc.'s common stock began trading the "regular way" under the ticker symbol "CTVA" on June 3, 2019, the first business day after June 1, 2019. Upon becoming an independent company, the capital structure of Corteva consisted of 748,815,000 authorized shares of common stock (par value of $0.01 per share), which represents the number of common shares issued on June 3, 2019. Information related to the Corteva Distribution and its effect on the company's financial statements is discussed throughout these Notes to the interim Consolidated Financial Statements.

As a result of the Business Realignment and the Internal Reorganization discussed above, Corteva owns, directly or indirectly, 100% of the outstanding common stock of EID, and EID owns, directly or indirectly, 100% of DAS. EID is a subsidiary of Corteva, Inc. and continues to be a reporting company, subject to the requirements of the Securities Exchange Act of 1934, as amended.

Combination of Entities under Common Control, Policy [Policy Text Block]

DAS Common Control Combination

The transfer or conveyance of DAS to Corteva was treated as a transfer of entities under common control. As such, the company recorded the assets, liabilities, and equity of DAS on its balance sheet at their historical basis. Transfers of businesses between entities under common control requires the financial statements to be presented as if the transaction had occurred at the point at which common control first existed (the Merger Effectiveness Time). As a result, the accompanying interim Consolidated Financial Statements and Notes thereto include the results of DAS from the Merger Effectiveness Time. See Note 4 - Common Control Business Combination, for additional information.

Principles of Consolidation and Basis of Presentation

Interim Financial Statements

The accompanying unaudited interim 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 unaudited interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto contained in the company’s Information Statement included in its Registration Statement on Form 10, as amended, filed with the SEC on May 6, 2019 ("Form 10").  The interim Consolidated Financial Statements include the accounts of the company and all of its subsidiaries in which a controlling interest is maintained.

Prior to the Corteva Distribution, these combined financial statements were derived from the consolidated financial statements and accounting records of EID as well as the carve-out financial statements of DAS. The DAS carve-out financial statements reflect the historical results of operations, financial position, and cash flows of Historical Dow's Agricultural Sciences Business and include allocations of certain expenses for services from Historical Dow, including, but not limited to, general corporate expenses related to finance, legal, information technology, human resources, ethics and compliance, shared services, employee benefits and incentives, insurance, and stock-based compensation. These expenses were allocated on the basis of direct usage when identifiable, with the remainder allocated under the basis of headcount or other measures. Subsequent to the Corteva Distribution, the financial statements are presented on a consolidated basis.

The company's Condensed Consolidated Balance Sheet at September 30, 2019 consists of the consolidated balances subsequent to the Corteva Distribution. The balances reflect the assets and liabilities that were historically included in the EID statements, as well as assets and liabilities transferred to the company as part of the common control combination acquisition of DAS. The company's Condensed Consolidated Balance Sheets at December 31, 2018 and September 30, 2018 consist of the combined balances of Historical EID and DAS. The Balance Sheets will be referred to as the "Condensed Consolidated Balance Sheets" throughout this document.

The company's Consolidated Statements of Operations (the "Consolidated Statements of Operations") for all periods prior to April 30, 2019 consist of the combined results of operations for Historical EID and DAS. The Consolidated Statements of Operations for all periods after May 2, 2019 represent the consolidated balances of the company.

All intercompany transactions have been eliminated.

As a condition of the regulatory approval for the Merger, including by the European Commission, EID was required to divest certain assets related to its crop protection business and research and development ("R&D") organization, specifically EID’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 (the “Divested EID Ag Business”).
