Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	BACKGROUND AND BASIS OF PRESENTATION Corteva, Inc. is a leading global provider of seed and crop protection solutions focused on the agriculture industry. The company intends to leverage its rich heritage of scientific achievement to advance its robust innovation pipeline and continue to shape the future of responsible agriculture. The company's broad portfolio of agriculture solutions fuels farmer productivity around the globe. Corteva has two reportable segments: seed and crop protection. See Note 23 - Segment Information, to the Consolidated Financial Statements, for additional information on the company's reportable segments. Throughout these financial statements, except as otherwise noted by the context, the terms "Corteva" or "company" used herein mean Corteva, Inc. and its consolidated subsidiaries (including EIDP) and the term “EIDP” used herein means EIDP, Inc. (formerly known as E. I. du Pont de Nemours and Company) and its consolidated subsidiaries or EIDP, Inc. excluding its consolidated subsidiaries, as the context may indicate. Principles of Consolidation and Basis of Presentation The consolidated financial statements contained in this Annual Report were prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") for all periods presented and include the accounts of the company, its majority owned subsidiaries over which the company exercises control. The Consolidated Financial Statements and other financial information included in this Annual Report, unless otherwise specified, have been presented to separately show the effects of discontinued operations. The company made the decision, which was retrospectively applied, to adjust the presentation of the Consolidated Statement of Cash Flows to separately show the cash provided by (used for) operating activities – discontinued operations, which was previously presented within cash provided by (used for) operating activities. See Note 16 – Commitments and Contingent Liabilities, to the Consolidated Financial Statements, for additional information on discontinued operations activities. On June 1, 2019, Corteva, Inc. became an independent, publicly traded company through the completed separation (the “Separation”) of the agriculture business of DuPont de Nemours, Inc. (formerly known as DowDuPont Inc.) (“DowDuPont” or “DuPont”). The separation was effectuated through a pro rata distribution (the “Corteva Distribution”) of all of the then-issued and outstanding shares of common stock of Corteva, Inc. Subsequent to the Merger, Historical Dow and EIDP engaged in a series of internal reorganization and realignment steps to realign their businesses into three subgroups: agriculture, materials science and specialty products ("Internal Reorganization"). On April 1, 2019, DowDuPont completed the separation of its materials science business into a separate and independent public company by way of a distribution of Dow common stock to holders of DowDuPont's common stock (the “Dow Distribution” and together with the Corteva Distribution, the “Distributions”). On April 1, 2019, Historical Dow entities, which held certain assets and liabilities aligned with Historical Dow’s agriculture business and the assets and liabilities associated with its specialty products business, respectively, were transferred and conveyed to DowDuPont. On April 1, 2019 and May 1, 2019, EIDP’s materials science and specialty products entities, along with their respective assets and liabilities, were conveyed to Dow and DowDuPont, respectively. On May 2, 2019, DowDuPont conveyed Historical Dow agricultural entities to EIDP. 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., then a wholly-owned subsidiary of DowDuPont, to DowDuPont stockholders. On May 31, 2019, DowDuPont contributed EIDP to Corteva, Inc. and on June 1, 2019, the Separation was completed. Information related to the Corteva Distribution and its effect on the company's financial statements is discussed throughout these Notes to the Consolidated Financial Statements. Since 2018, Argentina has been considered a hyper-inflationary economy under U.S. GAAP and therefore the U.S. Dollar (“USD”) is the functional currency for our related subsidiaries. Argentina contributes 4 percent and 3 percent to the company's annual net sales and segment operating EBITDA, respectively. The company remeasures net monetary assets and translates the financial statements utilizing the official Argentine Peso (“Peso”) to USD exchange rate. The ability to draw down Peso cash balances is limited at this time due to government restrictions and market availability of U.S. Dollars. The devaluation of the Peso relative to the USD over the last several years has resulted in the recognition of exchange losses (refer to Note 7 – Supplementary Information, to the Consolidated Financial Statements). As of December 31, 2023, a further 10 percent deterioration in the official Peso to USD exchange rate would reduce the USD value of our net monetary assets and negatively impact pre-tax earnings by approximately $10 million. The company will continue to assess the implications to its operations and financial reporting.
