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 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, 2019, collectively referred to as the “2019 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.

Basis of Presentation

Certain reclassifications of prior year's data have been made to conform to current year's presentation.  On April 1, 2019, EID completed the transference of 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”) to separate legal entities (the “Materials Science Entities”) that were ultimately conveyed by DowDuPont to Dow. On May 1, 2019, EID completed the transfer of the assets and liabilities aligned with the EID’s specialty products business to separate legal entities (“EID Specialty Products Entities”), which were then distributed to DowDuPont.

In accordance with GAAP, the financial position and results of operations of EID ECP and the EID Specialty Products Entities are presented as discontinued operations and, as such, have been excluded from continuing operations and segment results 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, comprehensive (loss) income, and equity related to EID ECP and the EID Specialty Products Entities have not been segregated and are included in the Condensed Consolidated Statements of Cash Flows, Consolidated Statements of Comprehensive Income (Loss), and Consolidated Statements of Equity, respectively, for all periods presented. Amounts related to EID ECP and the EID Specialty Products Entities are consistently included or excluded from the Notes to the interim Consolidated Financial Statements based on the respective financial statement line item. See Note 3 - Divestitures and Other Transactions, for additional information.

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. Beginning in the second quarter 2019, the financial statements are presented on a consolidated basis.

The company's Condensed Consolidated Balance Sheets at March 31, 2020 and December 31, 2019 consist of Corteva, Inc. and its consolidated subsidiaries. The company's Condensed Consolidated Balance Sheet at March 31, 2019 consists 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 1, 2019 represent the consolidated balances of the company. Intercompany balances and transactions with Historical EID and DAS have been eliminated.
