Corteva, Inc.

NOTE 17 -SEGMENT INFORMATION

Corteva’s reportable segments reflects the manner in which its chief operating decision maker ("CODM") allocates resources and assesses performance, which is at the operating segment level (Seed and Crop Protection). The company's CODM is the Chief Executive Officer. The primary measure used by Corteva's CODM for purposes of allocating resources to the segments and assessing segment performance is segment operating EBITDA.

Segment operating EBITDA is primarily utilized in the annual planning and monthly forecasting processes. On a monthly basis, the CODM considers variances between comparable prior year actual results and current year actual or forecasted results when evaluating the company's success in delivering its innovative proprietary technology to farmers and monitoring of expected savings from cost and productivity actions. The CODM also utilizes segment operating EBITDA when evaluating the impacts of market-driven trends on segment performance, such as input costs and inflationary and currency impacts.

The company defines segment operating EBITDA as earnings (loss) (i.e., income (loss) from continuing operations before income taxes) before interest, depreciation, amortization, corporate expenses, non-operating benefits (costs), foreign exchange gains (losses), and net unrealized gain or loss from mark-to-market activity for certain foreign currency derivative instruments that do not qualify for hedge accounting, excluding the impact of significant items. Non-operating benefits (costs) consists of non-operating pension and other post-employment benefit (OPEB) credits (costs), tax indemnification adjustments and environmental remediation and legal costs associated with legacy businesses and sites. Tax indemnification adjustments relate to changes in indemnification balances, as a result of the application of the terms of the Tax Matters Agreement, between Corteva and Dow and/or DuPont that are recorded by the company as pre-tax income or expense. Net unrealized gain or loss from mark-to-market activity for certain foreign currency derivative instruments that do not qualify for hedge accounting represents the non-cash net gain (loss) from changes in fair value of certain undesignated foreign currency derivative contracts. Upon settlement, which is within the same calendar year of execution of the contract, the realized gain (loss) from the changes in fair value of the non-qualified foreign currency derivative contracts will be reported in the respective segment results to reflect the economic effects of the foreign currency derivative contracts without the resulting unrealized mark to fair value volatility.
