Revenue from Contract with Customer [Abstract]

Revenue

REVENUE

Revenue Recognition

Products

Substantially all of Corteva's revenue is derived from product sales. Product sales consist of sales of Corteva's products to farmers, distributors, and manufacturers. Corteva considers purchase orders, which in some cases are governed by master supply agreements, to be a contract with a customer. Contracts with customers are considered to be short-term when the time between order confirmation and satisfaction of the performance obligations is equal to or less than one year. However, the company has some long-term contracts which can span multiple years.

Revenue from product sales is recognized when the customer obtains control of the company's product, which occurs at a point in time according to shipping terms. Payment terms are generally less than one year from invoicing. The company elected the practical expedient and does not adjust the promised amount of consideration for the effects of a significant financing component when the company expects it will be one year or less between when a customer obtains control of the company's product and when payment is due. The company has elected to recognize shipping and handling activities when control has transferred to the customer as an expense in cost of goods sold. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues. In addition, the company elected the practical expedient to expense any costs to obtain contracts as incurred, as the amortization period for these costs would have been one year or less.

The transaction price includes estimates of variable consideration, such as rights of return, rebates, and discounts, that are reductions in revenue. All estimates are based on the company's historical experience, anticipated performance, and the company's best judgment at the time the estimate is made. Estimates of variable consideration included in the transaction price utilize either the expected value method or most likely amount depending on the nature of the variable consideration. These

estimates are reassessed each reporting period and are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur upon resolution of uncertainty associated with the variable consideration. The majority of contracts have a single performance obligation satisfied at a point in time and the transaction price is stated in the contract, usually as quantity times price per unit. For contracts with multiple performance obligations, the company allocates the transaction price to each performance obligation based on the relative standalone selling price. The standalone selling price is the observable price which depicts the price as if sold to a similar customer in similar circumstances.

Licenses of Intellectual Property

Corteva enters into licensing arrangements with customers under which it licenses its intellectual property. Revenue from the majority of intellectual property licenses is derived from sales-based royalties. Revenue for licensing agreements that contain sales-based royalties is recognized at the later of (i) when the subsequent sale occurs or (ii) when the performance obligation to which some or all of the royalty has been allocated is satisfied.

Remaining Performance Obligations

Remaining performance obligations represent the transaction price allocated to unsatisfied or partially unsatisfied performance obligations. The company applies the practical expedient to disclose the transaction price allocated to remaining performance obligations for only those contracts with an original duration of one year or more. The transaction price allocated to remaining performance obligations with an original duration of more than one year related to material rights granted to customers for contract renewal options were $115 million and $108 million at December 31, 2020 and December 31, 2019, respectively. The company expects revenue to be recognized for the remaining performance obligations over the next 1 year to 6 years.

Contract Balances

Contract liabilities primarily reflect deferred revenue from prepayments under contracts with customers where the company receives advance payments for products to be delivered in future periods. Corteva classifies deferred revenue as current or noncurrent based on the timing of when the company expects to recognize revenue. Contract assets primarily include amounts related to contractual rights to consideration for completed performance not yet invoiced. Accounts receivable are recorded when the right to consideration becomes unconditional.

Disaggregation of Revenue

Corteva's operations are classified into two reportable segments: Seed and Crop Protection. The company disaggregates its revenue by major product line and geographic region, as the company believes it best depicts the nature, amount and timing of its revenue and cash flows. Net sales by major product line are included below:

1.Primarily consists of the acquisition of a distributor in Greece.

2.Primarily consists of the goodwill included in the sale of businesses in the crop protection segment.

The company tests goodwill for impairment annually (during the fourth quarter), or more frequently when events or changes in circumstances indicate it is more likely than not that the fair value of a reporting unit has declined below its carrying value. As mentioned in Note 2 - Summary of Significant Accounting Policies, as a result of the Internal Reorganizations and Business Realignments, the company changed its reportable segments to seed and crop protection to reflect the manner in which the company's chief operating decision maker assesses performance and allocates resources. The change in reportable segments resulted in changes to the company's reporting units for goodwill impairment testing to align with the level at which discrete financial information is available for review by management. The company’s reporting units include seed, crop protection and digital.

In connection with the change in reportable segments and reporting units in the second quarter of 2019, goodwill was reassigned from the former agriculture reporting unit to the seed, crop protection and digital reporting units using a relative fair value allocation approach. As a result, the company performed a goodwill impairment assessment for the former agriculture reporting unit immediately prior to the realignment and the newly created reporting units immediately after the realignment.

Additionally, during the second quarter of 2020, the company determined a triggering event had occurred as a result of changes in the company's long-term projections driven largely by the impacts of the COVID-19 pandemic on the mid-term forecasted cash flows of the business, including, but not limited to currency fluctuations, expectations of future planted area (as influenced by consumer demand, ethanol markets and government policies and regulations) and relative commodity prices, which required an interim impairment assessment for its seed and crop protection reporting units and trade name indefinite lived intangible asset. Based on the impairment analysis performed over the company’s trade name indefinite lived intangible asset it was determined that the fair value approximated the carrying value, and no impairment charge was necessary.

The company performed quantitative testing on all of its reporting units and determined that no goodwill impairments existed in 2019 and 2020.

During the third quarter of 2018, and in connection with strategic business reviews, the company assembled updated financial projections. The revised financial projections of the agriculture reporting unit assessed and quantified the impacts of developing market conditions, events and circumstances that have evolved throughout 2018, resulting in a reduction in the forecasts of sales and profitability as compared to prior forecasts. The reduction in financial projections was principally driven by lower growth in sales and margins in North America and Latin America and unfavorable currency impacts related to the Brazilian Real. The lower growth expectation was driven by reduced planted area, an expected unfavorable shift to soybeans from corn in Latin America, and delays in expected product registrations. In addition, decreases in commodity prices and higher than anticipated industry grain inventories were expected to impact farmers’ income and buying choices resulting in shifts to lower technologies and pricing pressure. The company considered the combination of these factors and the resulting reduction in its

forecasted projections for the agriculture reporting unit and determined it was more likely than not that the fair value of the agriculture reporting unit was less than the carrying value, thus requiring the performance of an updated goodwill and intangible asset impairment analysis for the agriculture reporting unit as of September 30, 2018.

For the year ended December 31, 2018, the company performed an interim impairment analysis for the agriculture reporting unit using a discounted cash flow model (a form of the income approach), utilizing Level 3 unobservable inputs. The company’s significant estimates in this analysis included, but were not limited to, future cash flow projections, Merger-related cost and growth synergies, the weighted average cost of capital, the terminal growth rate, and the tax rate. The company believed the current assumptions and estimates utilized were both reasonable and appropriate. The key assumption driving the change in fair value was the lower financial projections discussed above. Future cash flow estimates are, by their nature, subjective and actual results may differ materially from the company’s estimates. If the company’s ongoing estimates of future cash flows are not met, the company may have to record additional impairment charges in future periods. The company’s estimates of future cash flows are based on current regulatory and economic climates, recent operating results, and planned business strategy. These estimates could be negatively affected by changes in federal, state, or local regulations or economic downturns. Based on the analysis performed, the company determined that the carrying amount of the agriculture reporting unit exceeded its fair value resulting in a pre-tax, non-cash goodwill impairment charge of $4,503 million, reflected in goodwill impairment charge in the company’s Consolidated Statement of Operations for the year ended December 31, 2018. None of the charge was tax-deductible.

1.Beginning on October, 1, 2019, the company changed its indefinite life assertion of germplasm assets to definite lived with a useful life of 25 years. The change is a result of a more focused development effort of new seed products coupled with an intent to out license select germplasm on a nonexclusive basis. Prior to changing the useful life of the germplasm assets, the company tested the assets for impairment under ASC 350 - Intangibles, Goodwill and Other, concluding the assets were not impaired. The increase in accumulated amortization for the year ended December 31, 2020 when compared to the year ended December 31, 2019 is due to 2020 including a full year of amortization of germplasm assets.

2.Beginning on October 1, 2020, the company changed its indefinite life assertion of its trade name asset to definite lived with a useful life of 25 years. This change is the result of the launch of BrevantTM seed in the retail channel in the U.S. Prior to changing the useful life of the trade name asset, the company tested the asset for impairment under ASC 350 - Intangibles, Goodwill and Other, concluding the asset was not impaired.

3.Primarily consists of sales and farmer networks, marketing and manufacturing alliances and noncompetition agreements.

During the third quarter of 2019, and in connection with strategic product and portfolio reviews, the company determined that the fair value of certain intangible assets classified as developed technology, other intangible assets and IPR&D within the seed segment that primarily relate to heritage DAS intangibles previously acquired from Cooperativa Central de Pesquisa Agrícola's ("Coodetec") was less than the carrying value due to the company’s focus on advancing more competitive products and eliminating redundancy and complexity across the breeding programs. For IPR&D and developed technology, the company concluded these projects were abandoned. For other intangible assets, the company performed an impairment assessment using

the relief from royalty method (a form of the income approach) using Level 3 inputs within the fair value hierarchy. The significant assumptions used in the calculation included projected revenue, royalty rates and discount rates. These significant assumptions involve management judgment and estimates relating to future operating performance and economic conditions that may differ from actual cash flows. As a result, the company recorded a pre-tax, non-cash intangible asset impairment charge of $54 million ($41 million after-tax), which is reflected in restructuring and asset related charges - net, in the company's Consolidated Statements of Operations for the year ended December 31, 2019.

There were no indicators of impairment for the company’s other intangible assets that would suggest that the fair value is less than its carrying value at December 31, 2019, except for IPR&D. As a result of the company’s decision, during the fourth quarter of 2019, to accelerate the ramp up of the Enlist E3TM trait platform in the company’s soybean portfolio mix across all brands over the subsequent five years with minimal use of the Roundup Ready 2 Yield® and Roundup Ready 2 Xtend® traits thereafter for the remainder of the Roundup Ready 2 License Agreement, the company determined that certain IPR&D projects associated with Roundup Ready 2 Xtend® were not recoverable and were impaired. These IPR&D projects were either abandoned or tested for impairment using the relief from royalty method (a form of the income approach) using Level 3 inputs within the fair value hierarchy. The key assumptions used in the relief from royalty method calculation included projected revenue, royalty rates and discount rates. These key assumptions involve management judgment and estimates relating to future operating performance and economic conditions that may differ from actual cash flows. As a result, the company recorded a pre-tax, non-cash intangible asset charge of $90 million ($69 million after-tax), which is reflected in restructuring and asset related charges - net, in the company's Consolidated Statements of Operations for the year ended December 31, 2019.

During 2018, in reviewing the indefinite-lived intangible assets, the company also determined that the fair value of certain IPR&D assets had declined as a result of delays in timing of commercialization and increases to expected research and development costs. The company performed an analysis of the fair value using the relief from royalty method (a form of the income approach) using Level 3 inputs within the fair value hierarchy. The key assumptions used in the calculation included projected revenue, royalty rates and discount rates. These key assumptions involve management judgment and estimates relating to future operating performance and economic conditions that may differ from actual cash flows. As a result, the company recorded a pre-tax, non-cash intangible asset impairment charge of $85 million ($66 million after tax), which is reflected in restructuring and asset related charges - net, in the company's Consolidated Statement of Operations for the year ended December 31, 2018.

The aggregate pre-tax amortization expense from continuing operations for definite-lived intangible assets was $682 million, $475 million, and $391 million, for the year ended December 31, 2020, the year ended December 31, 2019, and the year ended December 31, 2018, respectively. Amortization expense for the year ended December 31, 2020 related to the trade name asset was $19 million (see discussion above for change in the indefinite life assertion).

The estimated annual future amortization expense related to the trade name asset is approximately $75 million per year.

Total estimated amortization expense for the next five fiscal years is as follows:

Recent Accounting Guidance Recent Accounting Guidance (Policies)	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Recent Accounting Guidance	RECENT ACCOUNTING GUIDANCE Recently Adopted Accounting Guidance In June 2016, the FASB issued ASU 2016-13, Financial Instruments (Topic 326): Credit Losses - Measurement of Credit Losses on Financial Statements, which requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. The amortized cost basis of financial assets should be reduced by expected credit losses to present the net carrying value in the financial statements at the amount expected to be collected. The measurement of expected credit losses is based on past events, historical experience, current conditions and forecasts that affect the collectability of the financial assets. Additionally, credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses. The company adopted the guidance in the first quarter of 2020. The primary impact of adoption related to the credit losses on accounts and notes receivable, which is applied using a cumulative-effect adjustment in the period of adoption, and prior periods are not restated. The adoption of ASU 2016-13 did not have a material impact on the company's financial position, results of operations or cash flows. See Note 10 - Accounts and Notes Receivable - Net, to the Consolidated Financial Statements, for additional information. In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606, which provides guidance on whether certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606 when the collaborative arrangement participant is a customer in the context of a unit of account. Accordingly, this amendment added unit of account guidance in Topic 606 when an entity is assessing whether the collaborative arrangement, or a part of the arrangement, is within the scope of Topic 606. In addition, the amendment provides certain guidance on presenting the collaborative arrangement transaction together with Topic 606. This ASU is to be applied retrospectively to the date of initial application of Topic 606. The company adopted this guidance on January 1, 2020 and it did not have a material impact on the company's financial position, results of operations or cash flows. In March 2020, the FASB issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848), which provides companies with optional financial reporting alternatives to reduce the cost and complexity associated with the accounting for contracts and hedging relationships affected by reference rate reform. The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022. The adoption of ASU 2020-04 did not have a material impact on the company's financial position, results of operations or cash flows, and will apply to future changes. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope, which provides certain optional expedients that allow derivative instruments impacted by changes in the interest rate used for margining, discounting or contract price alignment to qualify for certain optional relief. The amendments in this Update are effective immediately for all entities and may be applied retrospectively as of any date from the beginning of any interim period that includes March 12, 2020 or prospectively to new modifications subsequent to the issuance of this Update. The adoption of ASU 2021-01 did not have a material impact on the company’s financial position, results of operation or cash flows. Accounting Guidance Issued But Not Adopted as of December 31, 2020 In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which as part of the FASB’s Simplification Initiative to identify, evaluate, and improve areas of U.S. GAAP for which cost and complexity can be reduced, while maintaining or improving the usefulness of the information provided to users of financial statements. This ASU amends ASC 740, Income Taxes, by removing certain exceptions to the general principles, and clarifying and amending current guidance. The new standard is effective for fiscal years, and periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted, however all amended guidance must be adopted in the same period and should be reflected as of the beginning of the annual period if initially adopted and applied during an interim period. The company does not expect the impact of adoption to be material.

1 The year ended December 31, 2020 includes a loss of $(53) million and a gain of $27 million relating to the expected sale of the La Porte site, for which the company signed an agreement in 2020, and the sale of a business in Asia Pacific in the crop protection segment, respectively.

2 Includes net pre-tax exchange losses of $(82) million, $(51) million and $(68) million associated with the devaluation of the Argentine peso for the years ended December 31, 2020, 2019 and 2018, respectively.

3 Includes a $(50) million foreign exchange loss for the year ended December 31, 2018 related to adjustments to foreign currency exchange contracts as a result of U.S. tax reform, which is included within significant items.

4 Includes non-service related components of net periodic benefit credits (costs) (interest cost, expected return on plan assets, amortization of unrecognized (gain) loss, amortization of prior service benefit and settlement (loss) gain).

5 Miscellaneous (expenses) income - net, includes losses from sale of receivables, tax indemnification adjustments related 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, and other items. In addition, the year ended December 31, 2018 includes a $(53) million loss related to the deconsolidation of a subsidiary (refer to Note 25 - Segment Information). Refer to Note 12 - Accounts and Notes Receivable - Net, for additional information on losses on the sale of receivables.

The following table summarizes the impacts of the company's foreign currency hedging program on the company's results of operations. The company routinely uses foreign currency exchange contracts to offset its net exposures, by currency, related to the foreign currency-denominated monetary assets and liabilities. The objective of this program is to maintain an approximately balanced position in foreign currencies in order to minimize, on an after-tax basis, the effects of exchange rate changes on net monetary asset positions. The hedging program gains (losses) are largely taxable (tax deductible) in the United States (U.S.), whereas the offsetting exchange gains (losses) on the remeasurement of the net monetary asset positions are often not taxable (tax deductible) in their local jurisdictions. The net pre-tax exchange gains (losses) are recorded in other income (expense) - net and the related tax impact is recorded in provision for (benefit from) income taxes on continuing operations in the Consolidated Statements of Operations.

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:


For the Year Ended December 31, 2018

1.Accounts receivable – trade and notes receivable - trade are net of allowances of $208 million at December 31, 2020 and $174 million at December 31, 2019. Allowances are equal to the estimated uncollectible amounts. The allowance at December 31, 2020 is equal to the expected credit losses and was developed using a loss-rate method. The allowance at December 31, 2019 is equal to the estimated uncollectible amounts and is based on historical collection experience, current economic and market conditions, and review of the current status of customers' accounts.

2.Notes receivable – trade primarily consists of receivables for deferred payment loan programs for the sale of seed products to customers. These loans have terms of one year or less and are primarily concentrated in North America. The company maintains a rigid pre-approval process for extending credit to customers in order to manage overall risk and exposure associated with credit losses. As of December 31, 2020 and 2019, there were no significant impairments related to current loan agreements.

3.Other includes receivables in relation to indemnification assets, value added tax, general sales tax and other taxes. No individual group represents more than 10 percent of total receivables. In addition, Other includes amounts due from nonconsolidated affiliates of $106 million and $119 million as of December 31, 2020 and 2019, respectively.

Accounts and notes receivable are carried at the expected amount to be collected, which approximates fair value.

The company enters into various factoring agreements with third-party financial institutions to sell its trade receivables under both recourse and non-recourse agreements in exchange for cash proceeds. These financing arrangements result in a transfer of the company's receivables and risks to the third-party. As these transfers qualify as true sales under the applicable accounting guidance, the receivables are derecognized from the Consolidated Balance Sheets upon transfer, and the company receives a payment for the receivables from the third-party within a mutually agreed upon time period. For arrangements involving an element of recourse, which is typically provided through a guarantee of accounts in the event of customer default, the guarantee obligation is measured using market data from similar transactions and reported as a current liability in the Consolidated Balance Sheets.

Trade receivables sold under these agreements were $255 million, $328 million, and $133 million for the years ended December 31, 2020, 2019 and 2018, respectively. The trade receivables sold that remained outstanding under these agreements which include an element of recourse as of December 31, 2020 and December 31, 2019 were $157 million and $171 million, respectively. The net proceeds received were included in cash provided by operating activities in the Consolidated Statements of Cash Flows. The difference between the carrying amount of the trade receivables sold and the sum of the cash received is recorded as a loss on sale of receivables in other income (expense) - net in the Consolidated Statements of Operations. The loss on sale of receivables were $55 million, $44 million, and $25 million for the years ended December 31, 2020, 2019 and 2018, respectively. The guarantee obligations recorded as of December 31, 2020 and December 31, 2019 in the Consolidated Balance Sheets were not material. See Note 18 - Commitments and Contingent Liabilities, to the Consolidated Financial Statements, for additional information on the company’s guarantees.

DIVESTITURES AND OTHER TRANSACTIONS

Separation Agreements

In connection with the Distributions, DuPont, Corteva, and Dow (together, the “Parties” and each a “Party”) entered into certain agreements to effect the separation, provide for the allocation of DowDuPont’s assets, employees, liabilities and obligations (including its investments, property and employee benefits and tax-related assets and liabilities) among the Parties, and provide a framework for Corteva's relationship with Dow and DuPont following the separations and Distributions (collectively, the "Separation Agreements"). The Parties entered into, among other agreements, the following agreements:

•Separation and Distribution Agreement - Effective April 1, 2019, the Parties entered into an agreement that sets forth, among other things, the agreements among the Parties regarding the principal transactions necessary to effect the Distributions. It also sets forth other agreements that govern certain aspects of the Parties’ ongoing relationships after the completion of the Distributions (the "Corteva Separation Agreement").

•Tax Matters Agreement - The Parties entered into an agreement effective as of April 1, 2019 as amended on June 1, 2019 that governs their respective rights, responsibilities and obligations with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and other matters regarding taxes.

•Employee Matters Agreement - The Parties entered into an agreement that identifies employees and employee-related liabilities (and attributable assets) to be allocated (either retained, transferred and accepted, or assigned and assumed, as applicable) to the Parties as part of the Distributions and describes when and how the relevant transfers and assignments will occur.

•Intellectual Property Cross-License Agreement - Effective as of April 1, 2019 Corteva and Dow, and effective June 1, 2019 Corteva and DuPont entered into Intellectual Property Cross-License Agreements. The Intellectual Property Cross-License Agreements set forth the terms and conditions under which the applicable Parties may use in their respective businesses, following each of the Distributions, certain know-how (including trade secrets), copyrights, and software, and certain patents and standards, allocated to another Party pursuant to the Corteva Separation Agreement.

•Letter Agreement - DuPont and Corteva entered into a Letter Agreement. The Letter Agreement sets forth certain additional terms and conditions related to the Separation, including certain limitations on each party’s ability to transfer certain businesses and assets to third parties without assigning certain of such party’s indemnification obligations under the Corteva Separation Agreement to the other party to the transferee of such businesses and assets or meeting certain other alternative conditions.

DuPont

Pursuant to the Separation Agreements, DuPont and Corteva indemnifies the other against certain litigation, environmental, tax, workers' compensation and other liabilities that arose prior to the Corteva Distribution. The term of this indemnification is generally indefinite and includes defense costs and expenses, as well as monetary and non-monetary settlements and judgments. In connection with the recognition of liabilities related to these matters, the company records an indemnification asset when recovery is deemed probable. At December 31, 2020, the indemnification assets are $27 million within accounts and notes receivable - net and $51 million within other assets in the Consolidated Balance Sheet. At December 31, 2020, the indemnification liabilities are $5 million within accrued and other current liabilities and $79 million within other noncurrent obligations in the Consolidated Balance Sheet.

Dow

EID Specialty Products Divestiture

As discussed in Note 1 - Background and Basis of Presentation, on May 1, 2019, the company completed the transfer of the entities and related assets and liabilities of the EID Specialty Products Entities to DowDuPont.

As a result, the financial results of the EID Specialty Products Entities are reflected as discontinued operations, as summarized below:

EID Specialty Products Impairment

As a result of the Merger and related acquisition method of accounting, Historical DuPont's assets and liabilities were measured at fair value resulting in increases to the company’s goodwill and other intangible assets. The fair value valuation increased the risk that any declines in financial projections, including changes to key assumptions, could have a material, negative impact on the fair value of the company’s reporting units and assets, and therefore could result in an impairment.

As a result of the Internal Reorganization, in the second quarter of 2019, EID assessed the recoverability of the goodwill within the electronics and communications, protection solutions, nutrition and health, transportation and advanced polymers, packaging and specialty plastics, industrial biosciences, and clean technologies reporting units, and the overall carrying value of the net assets in the disposal group that was distributed to DowDuPont on May 1, 2019. As a result of this analysis, the company determined that the fair value of certain reporting units related to the EID specialty products businesses were below carrying value resulting in pre-tax, non-cash goodwill impairment charges totaling $1,102 million reflected in loss from discontinued operations after income taxes. Revised financial projections reflect unfavorable market conditions, driven by slowed demand in the biomaterials business unit, coupled with challenging conditions in U.S. bioethanol markets. These revised financial projections resulted in a reduction in the long-term forecasts of sales and profitability as compared to prior projections.

The company’s analyses above using discounted cash flow models (a form of the income approach) utilized Level 3 unobservable inputs. The company’s significant assumptions in these analyses include, but are not limited to, future cash flow projections, the weighted average cost of capital, the terminal growth rate, and the tax rate. The company’s estimates of future cash flows are based on current regulatory and economic climates, recent operating results, and planned business strategies. These estimates could be negatively affected by changes in federal, state, or local regulations or economic downturns. Future cash flow estimates are, by their nature, subjective and actual results may differ materially from the company’s estimates. The company also used a form of the market approach (utilizes Level 3 unobservable inputs), which is derived from metrics of publicly traded companies or historically completed transactions of comparable businesses. The selection of comparable businesses is based on the markets in which the reporting units operate giving consideration to risk profiles, size, geography, and diversity of products and services. As such, the company believes the current assumptions and estimates utilized are both reasonable and appropriate.

In addition, the company performed an impairment analysis related to the equity method investments held by the EID specialty products businesses, as of May 1, 2019. The company applied the net asset value method under the cost approach to determine the fair value of the equity method investments in the EID specialty products businesses. Based on updated projections, the company determined the fair value of an equity method investment was below the carrying value and had no expectation the fair value would recover in the short-term due to the current economic environment. As a result, management concluded the impairment was other-than-temporary and recorded an impairment charge of $63 million, reflected in loss from discontinued operations after income taxes. Additionally, this impairment is reflected within restructuring and asset related charges - net in the year ended December 31, 2019, within the table above.

The following table presents the depreciation, amortization of intangibles, and capital expenditures of the discontinued operations related to the EID Specialty Products Entities:


	For the Year Ended December 31,

Amortization of intangibles	267		815

Merger Remedy - Divested Ag Business

As a condition of the regulatory approval for the Merger, including by the European Commission, EID was required to divest (the “Divested Ag Business”) 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. On March 31, 2017, EID and FMC Corporation (“FMC”) entered into a definitive agreement (the "FMC Transaction Agreement"), and on November 1, 2017 FMC acquired the Divested Ag Business. As a result of the agreement, EID entered into favorable contracts with FMC of $495 million, which were recorded as intangible assets recognized at the fair value of off-market contracts.

For the year ended December 31, 2019, the company recorded income from discontinued operations after income taxes related to the Divested Ag Business of $80 million related to changes in accruals for certain prior year tax positions. For the year ended December 31, 2018, the company recorded a loss from discontinued operations before income taxes related to the Divested Ag Business of $(10) million, $(5) million after tax.

Performance Chemicals

On July 1, 2015, Historical DuPont completed the separation of its Performance Chemicals segment through the spin-off of all of the issued and outstanding stock of The Chemours Company (the "Chemours Separation"). In connection with the Chemours Separation, Historical DuPont and The Chemours Company ("Chemours") entered into a Separation Agreement (as amended, the "Chemours Separation Agreement"), discussed below, a Tax Matters Agreement and certain ancillary agreements, including an employee matters agreement, agreements related to transition and site services, and intellectual property cross licensing

arrangements. In addition, the companies have entered into certain supply agreements.

Separation Agreement

The Chemours Separation Agreement sets forth, among other things, the agreements between the company and Chemours regarding the principal transactions necessary to effect the Chemours Separation and also sets forth ancillary agreements that govern certain aspects of the company’s relationship with Chemours after the separation. Among other matters, the Chemours Separation Agreement and the ancillary agreements provide for the allocation between Historical DuPont and Chemours of

assets, employees, liabilities and obligations (including investments, property and employee benefits and tax-related assets and liabilities) attributable to periods prior to, at and after the completion of the Chemours Separation.

Pursuant to the Chemours Separation Agreement, Chemours indemnifies the company against certain litigation, environmental, workers' compensation and other liabilities that arose prior to the distribution. The term of this indemnification is generally indefinite and includes defense costs and expenses, as well as monetary and non-monetary settlements and judgments. In 2017, EID and Chemours amended the Chemours Separation Agreement to provide for a limited sharing of potential future perfluorooctanoic acid (“PFOA”) liabilities for a period of five years beginning July 6, 2017. In January 2021, Chemours, DuPont and Corteva entered into a binding memorandum of understanding ("MOU") amending the Chemours Separation Agreement, and thereby replacing the 2017 amendment.

In connection with the recognition of liabilities related to these matters, the company records an indemnification asset when recovery is deemed probable. At December 31, 2020, the indemnified assets are $66 million within accounts and notes receivable - net and $257 million within other assets (along with the corresponding liabilities within accrued and other current liabilities and other noncurrent obligations on the Consolidated Balance Sheet). Additionally, at December 31, 2020 the company recorded indemnification liabilities related to the MOU, primarily associated with environmental remediation related to PFAS, of $8 million within accrued and other current liabilities and $31 million within other noncurrent obligations in the Consolidated Balance Sheet with corresponding charges to (loss) income from discontinued operations after income taxes, during the year ended December 31, 2020.

In addition, in January 2021 Chemours, DuPont and Corteva agreed to settle approximately 95 matters, as well as unfiled matters remaining in the Ohio MDL, for $83 million, with Chemours contributing $29 million to the settlement, and DuPont and Corteva contributing $27 million each. The company has recorded a liability for its share of the settlement, with a charge to (loss) income from discontinued operations after income taxes, during the year ended December 31, 2020.

See Note 18 - Commitments and Contingent Liabilities, to the Consolidated Financial Statements, for further discussion of the amendment to the Chemours Separation Agreement, memorandum of understanding and certain litigation and environmental matters indemnified by Chemours.

Other Discontinued Operations Activity

For the year ended December 31, 2020, the company recorded income from discontinued operations after income taxes of $10 million related to the adjustment of certain prior year tax positions for previously divested businesses. For the year ended December 31, 2019, the company recorded income from discontinued operations after income taxes of $89 million related to the adjustment of certain unrecognized tax benefits for positions taken on items from prior years from previously divested businesses.

INCOME TAXES

On December 22, 2017, the Tax Cuts and Jobs Act (“The Act”) was enacted. The Act reduced the U.S. federal corporate income tax rate from 35 percent to 21 percent, required companies to pay a one-time transition tax (“transition tax”) on earnings of certain foreign subsidiaries that were previously tax deferred, created new provisions related to foreign sourced earnings, eliminated the domestic manufacturing deduction and moved to a territorial system. At December 31, 2017, the Company had not completed its accounting for the tax effects of The Act; however, as described below, the company made a reasonable estimate of the effects on its existing deferred tax balances and the one-time transition tax. In accordance with Staff Accounting Bulletin 118 ("SAB 118"), income tax effects of The Act were refined upon obtaining, preparing, or analyzing additional information during the measurement period.

At December 31, 2018, the company had completed its accounting for the tax effects of The Act.

•As a result of The Act, the company remeasured its U.S. federal deferred income tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21 percent. The company recorded a cumulative benefit of $(2,847) million (which includes a $(34) million benefit in the year ended December 31, 2018) to benefit from income taxes on continuing operations with respect to the remeasurement of the company's deferred tax balances. Of the $(34) million benefit, $(114) million relates to the company's discretionary pension contribution in 2018, which was deducted on a 2017 tax return. The remaining charges relate to purchase accounting adjustments made throughout 2018.

•The Act requires a mandatory deemed repatriation of post-1986 undistributed foreign earnings and profits (“E&P”), which results in a one-time transition tax. The company recorded a cumulative charge of $928 million (which includes a $182 million charge in the year ended December 31, 2018) to benefit from income taxes on continuing operations with respect to the one-time transition tax.

•In the year ended December 31, 2018, the company recorded a $16 million charge to benefit from income taxes on continuing operations associated with an indirect impact of The Act related to prepaid tax on the intercompany sale of inventory.

For tax years beginning after December 31, 2017, The Act introduces new provisions for U.S. taxation of certain global intangible low-taxed income (“GILTI”). The company has made the policy election to record any liability associated with GILTI in the period in which it is incurred.

Each year the company files hundreds of tax returns in the various national, state and local income taxing jurisdictions in which it operates. These tax returns are subject to examination and possible challenge by the tax authorities. Positions challenged by the tax authorities may be settled or appealed by the company. As a result, there is an uncertainty in income taxes recognized in the company's financial statements in accordance with accounting for income taxes and accounting for uncertainty in income taxes. It is reasonably possible that changes to the company’s global unrecognized tax benefits could be significant; however, due to the uncertainty regarding the timing of completion of audits and possible outcomes, a current estimate of the range of increases or decreases that may occur within the next twelve months cannot be made.

Tax years that remain subject to examination for the company’s major tax jurisdictions are shown below:

Undistributed earnings of foreign subsidiaries and related companies that are deemed to be indefinitely invested amounted to $4,130 million at December 31, 2020. As a result of the Act, distributions of profits from non-U.S. subsidiaries are not expected to cause a significant incremental U.S. tax impact in the future; however, those distributions may still be subject to certain taxes upon repatriation, primarily where foreign withholding taxes apply. The company is asserting indefinite reinvestment related to certain investments in foreign subsidiaries. Determination of the amount of unrecognized deferred tax liability related to indefinitely reinvested profits is not feasible primarily due to our legal entity structure and the complexity of U.S. and local tax laws.

For periods between the Merger Effectiveness Time and the Corteva Distribution, Corteva and its subsidiaries were included in DowDuPont's consolidated federal income tax group and consolidated tax return. Generally, the consolidated tax liability of the DowDuPont U.S. tax group for each year was apportioned among the members of the consolidated group based on each member’s separate taxable income. Corteva, DuPont and Dow intend that to the extent Federal and/or State corporate income tax liabilities are reduced through the utilization of tax attributes of the other, settlement of any receivable and payable generated from the use of the other party’s sub-group attributes will be in accordance with a tax sharing agreement and/or tax matters agreement. See Note 5 - Divestitures and Other Transactions, to the Consolidated Financial Statements for further information related to indemnifications between Corteva, Dow and DuPont.
