Accounting Policies [Abstract]

Basis of Consolidation

The Consolidated Financial Statements include the accounts of the company and subsidiaries in which a controlling interest is maintained. For those consolidated subsidiaries in which the company's ownership is less than 100 percent, the outside stockholders' interests are shown as noncontrolling interests. Investments in affiliates over which the company has the ability to exercise significant influence but does not have a controlling interest are accounted for under the equity method. The company is also involved with certain joint ventures accounted for under the equity method of accounting that are variable interest entities ("VIEs"). The company is not the primary beneficiary, as the nature of the company's involvement with the VIEs does not provide it the power to direct the VIEs significant activities. Future events may require these VIEs to be consolidated if the company becomes the primary beneficiary. At December 31, 2021 and 2020, the maximum exposure to loss related to the nonconsolidated VIEs is not considered material to the Consolidated Financial Statements.

Use of Estimates in Financial Statement PreparationThe preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The company’s consolidated financial statements include amounts that are based on management’s best estimates and judgments. Actual results could differ from those estimates.

Cash and Cash EquivalentsCash equivalents represent investments with maturities of three months or less from time of purchase. They are carried at cost plus accrued interest.

Restricted Cash

Restricted Cash Equivalents

Restricted cash equivalents primarily consist of trust assets and contributions to the MOU Escrow Account of $377 million and $347 million as of December 31, 2021 and 2020, respectively. The trust assets are classified as current and the contributions to the MOU Escrow Account are classified as noncurrent and included within other current assets and other assets, respectively, in the Consolidated Balance Sheets. See Note 9 - Supplementary Information, to the Consolidated Financial Statements, for further information.

Marketable Securities

Marketable securities represent investments in fixed and floating rate financial instruments with maturities greater than three months and up to twelve months at time of purchase. Investments classified as held-to-maturity are recorded at amortized cost. The carrying value approximates fair value due to the short-term nature of the investments. Investments classified as debt securities that are available-for-sale are carried at estimated fair value with unrealized gains and losses recorded as a component of accumulated other comprehensive income (loss) or current period earnings if an allowance for credit losses has been established. The cost of investments sold is determined by specific identification.

Fair Value Measurements

Under the accounting guidance for fair value measurements and disclosures, a fair value hierarchy was established that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The company uses the following valuation techniques to measure fair value for its assets and liabilities:


Level 1	–	Quoted market prices in active markets for identical assets or liabilities;

Level 2	–	Significant other observable inputs (e.g. quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs other than quoted prices that are observable such as interest rate and yield curves, and market-corroborated inputs);

Level 3	–	Unobservable inputs for the asset or liability, which are valued based on management's estimates of assumptions that market participants would use in pricing the asset or liability.

Foreign Currency Translation

The company's worldwide operations utilize the U.S. dollar ("USD") or a related foreign currency as the functional currency, where applicable. The company identifies its separate and distinct foreign entities and groups the foreign entities into two categories: 1) extension of the parent or foreign subsidiaries operating in a hyper-inflationary environment (USD functional currency) and 2) self-contained (related foreign functional currency). If a foreign entity does not align with either category, factors are evaluated and a judgment is made to determine the functional currency.

For foreign entities where the USD is the functional currency, all foreign currency-denominated asset and liability amounts are re-measured into USD at end-of-period exchange rates, except for inventories, prepaid expenses, property, plant and equipment, goodwill and other intangible assets, which are re-measured at historical rates. Foreign currency income and expenses are re-measured at average exchange rates in effect during each month, except for expenses related to balance sheet amounts re-measured at historical exchange rates. Exchange gains and losses arising from re-measurement of foreign currency-denominated monetary assets and liabilities are included in income in the period in which they occur.

For foreign entities where a related foreign currency is the functional currency, assets and liabilities denominated in the related foreign currencies are translated into USD at end-of-period exchange rates and the resultant translation adjustments are reported, net of their related tax effects, as a component of accumulated other comprehensive income (loss) in equity. Assets and liabilities denominated in other than the functional currency are re-measured into the functional currency prior to translation into USD and the resultant exchange gains or losses are included in income in the period in which they occur. Income and expenses are translated into USD at average exchange rates in effect during each month.

The company changes the functional currency of its separate and distinct foreign entities only when significant changes in economic facts and circumstances indicate clearly that the functional currency has changed.

Inventories

The company's inventories are valued at the lower of cost or net realizable value. Elements of cost in inventories include raw materials, direct labor and manufacturing overhead. Stores and supplies are valued at cost or net realizable value, whichever is lower; cost is generally determined by the average cost method.

As of December 31, 2021 and December 31, 2020, approximately 60% and 40% of the company's inventories were accounted for under the first-in, first-out ("FIFO") and average cost methods, respectively. Inventories accounted for under the FIFO method are primarily comprised of products with shorter shelf lives such as seeds. See Note 13 - Inventories, to the Consolidated Financial Statements, for further information.

The company establishes an obsolescence reserve for inventory based upon quality considerations and assumptions about future demand and market conditions.

Property, Plant and Equipment

Property, plant and equipment are carried at cost less accumulated depreciation. In connection with the Merger, the fair value of property, plant and equipment was determined using a market approach and a replacement cost approach. Depreciation is based on the estimated service lives of depreciable assets and is calculated using the straight-line method. Fully depreciated assets are retained in property and accumulated depreciation accounts until they are removed from service. When assets are surrendered, retired, sold, or otherwise disposed of, their gross carrying values and related accumulated depreciation are removed from the Consolidated Balance Sheets and included in determining gain or loss on such disposals.

Goodwill and Other Intangible Assets

The company records goodwill when the purchase price of a business acquisition exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill is tested for impairment at the reporting unit level at least annually, or more frequently when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. The company performs an annual goodwill impairment test in the fourth quarter.

When testing goodwill for impairment, the company has the option to first perform qualitative testing to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the company chooses not to complete a qualitative assessment for a given reporting unit or if the initial assessment indicates that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value, additional quantitative testing is required. If additional quantitative testing is required, the reporting unit's fair value is compared with its carrying amount, and an impairment charge, if any, is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value, limited to the amount of goodwill associated with the reporting unit. The company determines fair values for each of the reporting units using a discounted cash flow model (a form of the income approach) or the market approach. Under the income approach, fair value is determined based on the present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate. The company's significant assumptions in this analysis included future cash flow projections, weighted average cost of capital, the terminal growth rate, and the tax rate. Under the market approach, the company uses metrics of publicly traded companies or historically completed transactions for comparable companies. See Note 15 - Goodwill and Other Intangible Assets, to the Consolidated Financial Statements, for further information on goodwill.

Indefinite-lived intangible assets are tested for impairment at least annually; however, these tests are performed more frequently when events or changes in circumstances indicate that the asset may be impaired. Impairment exists when carrying value exceeds fair value. The company performs 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, the royalty rate, the discount rate, and the terminal growth rate. These significant assumptions involve management judgment and estimates relating to future operating performance and economic conditions that may differ from actual cash flows.

Definite-lived intangible assets are amortized over their estimated useful lives, generally on a straight-line basis for periods ranging primarily from 2 years to 25 years. The company continually evaluates the reasonableness of the useful lives of these assets. Once these assets are fully amortized, they are removed from the Consolidated Balance Sheets.

Leases

The company determines whether an arrangement is a lease at the inception of the arrangement based on the terms and conditions in the contract. A contract contains a lease if there is an identified asset and the company has the right to control the asset. Operating lease right-of-use ("ROU") assets are included in other assets on the company’s Consolidated Balance Sheets. Operating lease liabilities are included in accrued and other current liabilities and other noncurrent obligations on the company’s Consolidated Balance Sheets. Finance lease assets are included in property, plant and equipment on the company’s Consolidated Balance Sheets. Finance lease liabilities are included in short-term borrowings and finance lease obligations and long-term debt on the company’s Consolidated Balance Sheets.

Operating lease ROU assets represent the company’s right to use an underlying asset for the lease term and lease liabilities represent the company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of the company’s leases do not provide the lessor's implicit rate, the company uses its incremental borrowing rate at the commencement date in determining the present value of lease payments. Lease terms include options to extend the lease when it is reasonably certain those options will be exercised. Leases with an initial term of 12 months or less are not recorded on the balance sheet. The company recognizes lease expense for these leases on a straight-line basis over the lease term.

The company has lease agreements with lease and non-lease components, which are accounted for as a single lease component for all asset classes. In the Consolidated Statements of Operations, lease expense for operating leases is recognized on a straight-line basis over the lease term. For finance leases, interest expense is recognized on the lease liability and the ROU asset is amortized over the lease term. See Note 16 - Leases, to the Consolidated Financial Statements, for further information.

Impairment of Long-Lived Assets

The company evaluates the carrying value of long-lived assets to be held and used when events or changes in circumstances indicate the carrying value may not be recoverable. The carrying value of a long-lived asset group is considered impaired when the total projected undiscounted cash flows from the assets are separately identifiable and are less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset. The

company's fair value methodology is an estimate of fair market value which is made based on prices of similar assets or other valuation methodologies including present value techniques. Long-lived assets to be disposed of by sale, if material, are classified as held for sale and reported at the lower of carrying amount or fair value less cost to sell, and depreciation is ceased. Long-lived assets to be disposed of other than by sale are classified as held and used until they are disposed of and reported at the lower of carrying amount or fair value. Depreciation is recognized over the remaining useful life of the assets.

Derivative Instruments

Derivative instruments are reported in the Consolidated Balance Sheets at their fair values. The company utilizes derivatives to manage exposures to foreign currency exchange rates and commodity prices. Changes in the fair values of derivative instruments that are not designated as hedges are recorded in current period earnings. For derivative instruments designated as cash flow hedges, the gain (loss) is reported in accumulated other comprehensive income (loss) until it is cleared to earnings during the same period in which the hedged item affects earnings. For derivative instruments designated as net investment hedges, the gain (loss) is reported within accumulated other comprehensive income (loss) until the subsidiary is divested.

In the event that a derivative designated as a hedge of a firm commitment or an anticipated transaction is terminated prior to the maturation of the hedged transaction, the net gain or loss in accumulated other comprehensive income (loss) generally remains in accumulated other comprehensive income (loss) until the item that was hedged affects earnings. If a hedged transaction matures, or is sold, extinguished, or terminated prior to the maturity of a derivative designated as a hedge of such transaction, gains or losses associated with the derivative through the date the transaction matured are included in the measurement of the hedged transaction and the derivative is reclassified as for trading purposes. Derivatives designated as hedges of anticipated transactions are reclassified as for trading purposes if the anticipated transaction is no longer probable.

The company included foreign currency exchange contract settlements within cash flows from operating activities, regardless of hedge accounting qualification. See Note 22 - Financial Instruments, to the Consolidated Financial Statements, for additional discussion regarding the company's objectives and strategies for derivative instruments.

Environmental Matters

Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. These accruals are adjusted periodically as assessment and remediation efforts progress or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the Consolidated Balance Sheets in accrued and other current liabilities and other noncurrent obligations at undiscounted amounts. Accruals for related insurance or other third-party recoveries for environmental liabilities are recorded when it is probable that a recovery will be realized and are included in the Consolidated Balance Sheets as accounts and notes receivable - net.

Environmental costs are capitalized if the costs extend the life of the property, increase its capacity, and/or mitigate or prevent contamination from future operations. Environmental costs are also capitalized in recognition of legal asset retirement obligations resulting from the acquisition, construction and/or normal operation of a long-lived asset. Costs related to environmental contamination treatment and cleanup are charged to expense. Estimated future incremental operations, maintenance and management costs directly related to remediation are accrued when such costs are probable and reasonably estimable.

Revenue Recognition

The company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the company expects to receive in exchange for those goods or services. To determine revenue recognition for the arrangements that the company determines are within the scope of FASB ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), the company performs the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. See Note 6 - Revenue, to the Consolidated Financial Statements, for additional information on revenue recognition.

Royalty Expense

Prepaid Royalties

The company currently has certain third-party biotechnology trait license agreements, which require up-front and variable payments subject to the licensor meeting certain conditions. These payments are reflected as other current assets and other assets and are amortized to cost of goods sold as seeds containing the respective trait technology are utilized over the life of the license. The rate of royalty amortization expense recognized is based on the company’s strategic plans which include various assumptions and estimates including product portfolio, market dynamics, farmer preferences, growth rates and projected planted acres. Changes in factors and assumptions included in the strategic plans, including potential changes to the product portfolio in favor of internally developed biotechnology, could impact the rate of recognition of the relevant prepaid royalty.

At December 31, 2021, the balance of prepaid royalties reflected in other current assets and other assets was $303 million and $256 million, respectively. The majority of the balance of prepaid royalties relates to the company’s wholly owned subsidiary, Pioneer Hi-Bred International, Inc.’s (“Pioneer”) non-exclusive license in the United States and Canada for the Monsanto Company's Genuity® Roundup Ready 2 Yield® glyphosate tolerance trait and Roundup Ready 2 Xtend® glyphosate and dicamba tolerance trait for soybeans (“Roundup Ready 2 License Agreement”). Each of these licensed technologies are now trademarks of the Bayer Group, which acquired the Monsanto Company in 2018. The prepaid royalty asset relates to a series of up-front, fixed and variable royalty payments to utilize the traits in Pioneer’s soybean product mix.The company’s historical expectation has been that the technology licensed under the Roundup Ready 2 License Agreement would be used as the primary herbicide tolerance trait platform in the Pioneer® brand soybean through the term of the agreement. DAS and MS Technologies, L.L.C. jointly developed and own the Enlist E3TM herbicide tolerance trait for soybeans which provides tolerance to 2, 4-D choline in Enlist Duo® and Enlist One® herbicides, as well as glyphosate and glufosinate herbicides. In connection with the validation of breeding plans and large-scale product development timelines, during the fourth quarter of 2019, the company accelerated the ramp up of the Enlist E3TM trait platform in the company’s soybean portfolio mix across all brands, including Pioneer® brands, over the subsequent five years. During the ramp-up period, the company is expected to significantly reduce the volume of products with the Roundup Ready 2 Yield® and Roundup Ready 2 Xtend® herbicide tolerance traits beginning in 2021, with expected minimal use of the trait platform thereafter for the remainder of the Roundup Ready 2 License Agreement (the “Transition Plan”). The rate of royalty expense has therefore increased significantly through higher amortization of the prepaid royalty as fewer seeds containing the respective trait are expected to be utilized.

In connection with the departure from these traits, beginning January 1, 2020 the company presents and discloses the non-cash accelerated prepaid royalty amortization expense as a component of restructuring and asset related charges - net, in the Consolidated Statement of Operations. The accelerated prepaid royalty amortization expense represents the difference between the rate of amortization based on the revised number of units expected to contain the Roundup Ready 2 Yield® and Roundup Ready 2 Xtend® trait technology and the variable cash rate per the Roundup Ready 2 License Agreement.

Further changes in factors and assumptions associated with usage of the trait platform licensed under the Roundup Ready 2 License Agreement, including the Transition Plan, could further impact the rate of recognition of the prepaid royalty and Consolidated Statement of Operations presentation of the accelerated prepaid royalty amortization expense.

Cost of Goods Sold

Cost of Goods Sold Cost of goods sold primarily includes the cost of manufacture and delivery, ingredients or raw materials, direct salaries, wages and benefits and overhead, non-capitalizable costs associated with capital projects, royalties and other operational expenses. No amortization of intangibles is included within cost of goods sold.

Research and Development

Research and development costs are expensed as incurred. Research and development expense includes costs (primarily consisting of employee costs, materials, contract services, research agreements, and other external spend) relating to the discovery and development of new products.

Selling, General and Administrative Expenses

Selling, General and Administrative Expenses Selling, general and administrative expenses primarily include selling and marketing expenses, commissions, functional costs, and business management expenses.

Integration and Separation Costs

Integration and separation costs includes costs incurred to prepare for and close the Merger, post-Merger integration expenses, and costs incurred to prepare for the Business Separations. These costs primarily consist of financial advisory, information technology, legal, accounting, consulting and other professional advisory fees associated with preparation and execution of these activities.

Litigation

Litigation and Other ContingenciesAccruals for legal matters and other contingencies are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Legal costs, such as outside counsel fees and expenses, are charged to expense in the period incurred.

Severance Costs

Severance CostsSeverance benefits are provided to employees under the company's ongoing benefit arrangements. Severance costs are accrued when management commits to a plan of termination and it becomes probable that employees will be entitled to benefits at amounts that can be reasonably estimated.

Insurance and Self Insurance

Insurance/Self-Insurance

The company self-insures certain risks where permitted by law or regulation, including workers' compensation, vehicle liability and employee related benefits. Liabilities associated with these risks are estimated in part by considering historical claims experience, demographic factors and other actuarial assumptions. For other risks, the company uses a combination of insurance and self-insurance, reflecting comprehensive reviews of relevant risks. A receivable for an insurance recovery is generally recognized when the loss has occurred and collection is considered probable.

Income Taxes

The company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities using enacted tax rates. The effect of a change in tax rates on deferred tax assets or liabilities is recognized in income in the period that includes the enactment date.

The company recognizes the financial statement effects of an uncertain income tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The current portion of uncertain income tax positions is included in income taxes payable or income tax receivable, and the long-term portion is included in other noncurrent obligations or other noncurrent assets in the Consolidated Balance Sheets.

Income tax related penalties are included in the provision for (benefit from) income taxes in the Consolidated Statements of Operations. Interest accrued related to unrecognized tax benefits is included within the provision for (benefit from) income taxes from continuing operations in the Consolidated Statements of Operations.

Earnings Per Share, Policy [Policy Text Block]

Earnings per Common Share

The calculation of earnings per common share is based on the weighted-average number of the company’s common shares outstanding for the applicable period. The calculation of diluted earnings per common share reflects the effect of all potential common shares that were outstanding during the respective periods, unless the effect of doing so is antidilutive.

The estimated fair value of the company's long-term borrowings, was determined using Level 2 inputs within the fair value hierarchy, as described in Note 2 - Summary of Significant Accounting Policies. Based on quoted market prices for the same or similar issues, or on current rates offered to the company for debt of the same remaining maturities, the fair value of the company's long-term borrowings, not including long-term debt due within one year, was $1,120 million and $1,166 million at December 31, 2021 and 2020, respectively.

Debt Offering

In May 2020, EID issued $500 million of 1.70 percent Senior Notes due 2025 and $500 million of 2.30 percent Senior Notes due 2030 (the May 2020 Debt Offering). The proceeds of this offering are intended to be used for general corporate purposes.

Revolving Credit Facilities

In November 2018, EID entered into a $3.0 billion, 5 year revolving credit facility and a $3.0 billion, 3-year revolving credit facility (the "Revolving Credit Facilities”). The Revolving Credit Facilities became effective May 2019. Corteva, Inc. became a party at the time of the Corteva Distribution. In May 2021, the company entered into an amendment that extended the maturity date of the 3-year revolving credit facility from May 2022 to May 2023. Other than the change in maturity date, there were no material modifications to the terms of the credit facility. The Revolving Credit Facilities may serve as a substitute to the company's commercial paper program, and can be used from time to time, for general corporate purposes including, but not limited to, the funding of seasonal working capital needs. The Revolving Credit Facilities contain customary representations and warranties, affirmative and negative covenants and events of default that are typical for companies with similar credit ratings. Additionally, the Revolving Credit Facilities contain a financial covenant requiring that the ratio of total indebtedness to total capitalization for Corteva and its consolidated subsidiaries not exceed 0.60.

In March 2020, the company drew down $500 million under the $3.0 billion 3-year revolving credit facility as a result of the volatility and increased borrowing costs of commercial paper resulting from the unstable market conditions caused by the COVID-19 pandemic and repaid that borrowing in full in June 2020. There were no additional borrowings and the unused commitments under the 3-year revolving credit facility were $3.0 billion as of December 31, 2021.

Debt Redemptions/Repayments

On March 22, 2019, EID issued notices of redemption in full of all of its outstanding notes (the “Make Whole Notes”) listed in the table below:


(in millions)	Amount
4.625% Notes due 2020	$	474
3.625% Notes due 2021	296
4.250% Notes due 2021	163
2.800% Notes due 2023	381
6.500% Debentures due 2028	57
5.600% Senior Notes due 2036	42
4.900% Notes due 2041	48
4.150% Notes due 2043	69
Total	$	1,530

The Make Whole Notes were redeemed on April 22, 2019 at the make-whole redemption prices set forth in the respective Make Whole Notes. On and after the date of redemption, the Make Whole Notes were no longer deemed outstanding, interest on the Make Whole Notes ceased to accrue and all rights of the holders of the Make Whole Notes were terminated.

In March 2016, EID entered into a credit agreement that provided for a 3-year, senior unsecured term loan facility in the aggregate principal amount of $4.5 billion (as amended, from time to time, the "Term Loan Facility") under which EID could make up to seven term loan borrowings and amounts repaid or prepaid were not available for subsequent borrowings. On May 2, 2019, EID terminated its Term Loan Facility and repaid the aggregate outstanding principal amount of $3 billion plus accrued and unpaid interest through and including May 1, 2019.

In connection with the repayment of the Make Whole Notes and the Term Loan Facility, EID paid a total of $4.6 billion in the second quarter 2019, which included breakage fees and accrued and unpaid interest on the Make Whole Notes and Term Loan Facility. The repayment of the Make Whole Notes and Term Loan Facility was funded with cash from operations and a contribution from DowDuPont.

On May 7, 2019, DowDuPont publicly announced the record date in connection with the Corteva Distribution. In connection with such announcement, EID was required to redeem $1.25 billion aggregate principal amount of 2.20% Notes due 2020 and $750 million aggregate principal amount of Floating Rate Notes due 2020 (collectively, the Special Mandatory Redemption, or “SMR Notes”) setting forth the date of redemption of the SMR Notes. On May 17, 2019 EID redeemed and paid a total of $2 billion, which included accrued and unpaid interest on the SMR Notes. EID funded the payment with a contribution from DowDuPont. Following the redemption, the SMR Notes are no longer outstanding and no longer bear interest, and all rights of the holders of the SMR Notes have terminated.

EID recorded a loss on the early extinguishment of debt of $13 million for the year ended December 31, 2019, related to the difference between the redemption price and the par value of the Make Whole Notes, the Term Loan Facility, and the SMR Notes, partially offset by the write-off of unamortized step-up related to the fair value step-up of EID’s debt.

Uncommitted Credit Facilities and Outstanding Letters of Credit

Unused bank credit lines on uncommitted credit facilities were $389 million at December 31, 2021. These lines are available to support short-term liquidity needs and general corporate purposes, including letters of credit. Outstanding letters of credit were $127 million at December 31, 2021. These letters of credit support commitments made in the ordinary course of business.

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Equity [Abstract]

STOCKHOLDERS' EQUITY

Common Stock

As discussed in Note 1 - Background and Basis of Presentation, on June 1, 2019, Corteva, Inc.'s common stock was distributed to DowDuPont stockholders by way of a pro rata distribution. Each DowDuPont stockholder received one share of Corteva, Inc. 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. The number of Corteva, Inc. common shares issued on June 1, 2019 was 748,815,000 (par value of $0.01 per share). Information related to the Corteva Distribution and its effect on the company's financial statements are discussed throughout these Notes to the Consolidated Financial Statements.

Set forth below is a reconciliation of common stock share activity for the years ended December 31, 2021, 2020, and 2019:


Shares of common stock			Issued
Balance June 1, 2019			748,815,000
Issued			586,000
Repurchased and retired			(824,000)
Balance December 31, 2019			748,577,000
Issued			3,384,000
Repurchased and retired			(8,503,000)
Balance December 31, 2020			743,458,000
Issued			4,019,000
Repurchased and retired			(20,950,000)

Balance December 31, 2021			726,527,000

Share Buyback Plan

On August 5, 2021, Corteva, Inc. announced that its Board of Directors authorized a $1.5 billion share repurchase program to purchase Corteva, Inc.'s common stock, par value $0.01 per share, without an expiration date ("2021 Share Buyback Plan"). The timing, price and volume of purchases will be based on market conditions, relevant securities laws and other factors. In connection with the 2021 Share Buyback Plan, the company purchased and retired 5,572,000 shares during the year ended December 31, 2021 in the open market for a total cost of $250 million.

On June 26, 2019, Corteva, Inc. announced that its Board of Directors authorized a $1 billion share repurchase program to purchase Corteva, Inc.'s common stock, par value $0.01 per share, without an expiration date ("2019 Share Buyback Plan").

In connection with the 2019 Share Buyback Plan, the company repurchased and retired 15,378,000 shares, 8,503,000 shares, and 824,000 shares in the open market for a total cost of $700 million, $275 million, and $25 million during the years ended December 31, 2021, 2020, and 2019, respectively. Repurchases under the 2019 Share Buyback Plan were completed during the third quarter of 2021.

Shares repurchased pursuant to Corteva's share buyback plan are immediately retired upon repurchase. Repurchased common stock is reflected as a reduction of stockholders' equity. The company's accounting policy related to its share repurchases is to reduce its common stock based on the par value of the shares and to reduce its retained earnings for the excess of the repurchase price over the par value. When Corteva has an accumulated deficit balance, the excess over the par value is applied to APIC. When Corteva has retained earnings, the excess is charged entirely to retained earnings.

Noncontrolling Interest

In June 2020, the company completed the acquisition of the remaining 46.5 percent interest in the Phytogen Seed Company, LLC joint venture from J. G. Boswell Company. As the purchase of the remaining interest did not result in a change of control, the difference between the carrying value of the noncontrolling interest and the consideration paid, net of taxes was recorded within equity.

Corteva, Inc. owns 100 percent of the outstanding common shares of EID. However, EID has preferred stock outstanding to third parties which is accounted for as a noncontrolling interest in Corteva's Consolidated Balance Sheets. Each share of EID

Preferred Stock - $4.50 Series and EID Preferred Stock - $3.50 Series issued and outstanding at the effective date of the Corteva Distribution remains issued and outstanding as to EID and was unaffected by the Corteva Distribution.

Below is a summary of the EID Preferred Stock at December 31, 2021 and December 31, 2020 which is classified as noncontrolling interests in the Corteva Consolidated Balance Sheets.


(Shares in thousands)			Number of Shares
Authorized			23,000

$3.50 Series, callable at $102			700

1.The cumulative translation adjustment losses for the year ended December 31, 2021 was primarily driven by the strengthening of the U.S. Dollar ("USD") against the European Euro ("EUR"), Swiss franc ("CHF") and Turkish Lira (“TRY”). The cumulative translation adjustment losses for the year ended December 31, 2020 was primarily driven by the strengthening of the U.S. Dollar ("USD") against the Brazilian Real ("BRL"), partially offset by the weakening of the U.S. Dollar against the Swiss franc ("CHF") and European Euro ("EUR").

Other Post Employment Benefits

The company has historically provided medical, dental and life insurance benefits to certain pensioners and survivors. The majority of U.S. employees hired on or after January 1, 2007, and eligible employees under the age of 50 as of November 30, 2018, are not eligible to participate in the post-employment medical, dental and life insurance plans. Substantially all of the cost and liabilities for these retiree benefit plans are attributable to the U.S. benefit plans. The non-Medicare eligible retiree medical plan is contributory with costs shared between the company and pensioners and survivors. For Medicare eligible pensioners and survivors, Corteva provides a company-funded Health Reimbursement Arrangement ("HRA"). In December 2020, the company amended its retiree medical, dental and life insurance plans resulting in the company no longer providing retiree dental and life insurance benefits effective January 1, 2022 and Corteva’s portion of the cost of non-Medicare retiree medical coverage no longer being adjusted for cost increases, which capped the Corteva cost at the level in effect as of December 31, 2021 ("2020 OPEB Plan Amendments"). As a result of these changes, the company recorded a $(939) million decrease in OPEB benefit obligations as of December 31, 2020 with a corresponding prior service benefit within other comprehensive income for the year ended December 31, 2020. During 2021, a substantial amount of the prior service benefit within other comprehensive income (loss) in 2020 was recognized in other income - net in the Consolidated Statement of Operations.

The company also provides disability benefits to employees. Employee disability benefit plans are insured in many countries. However, primarily in the U.S., such plans are generally self-insured. Obligations and expenses for self-insured plans are reflected in the change in projected benefit obligations table on page F-56.

The company's OPEB plans are unfunded and the cost of the approved claims is paid from operating cash flows. Pre-tax cash requirements to cover actual net claims costs and related administrative expenses were $198 million, $207 million, and $202 million for the years ended December 31, 2021, 2020 and 2019, respectively. Changes in cash requirements reflect the net impact of per capita health care costs, demographic changes, plan amendments and changes in participant premiums, co-pays and deductibles. In 2022, the company expects to contribute approximately $140 million for its OPEB plans.

The weighted-average assumptions used to determine benefit obligations for OPEB plans are summarized in the table below:


Weighted-Average Assumptions used to Determine Benefit Obligations	December 31, 2021		December 31, 2020
Discount rate	2.59	%	2.09	%

The weighted-average assumptions used to determine net periodic benefit costs for the OPEB plans are summarized in the two tables below:


Weighted-Average Assumptions used to Determine Net Periodic Benefit Cost	For the Year Ended December 31,
	2021		2020		2019
Discount rate	2.09	%	3.07	%	3.93	%

Assumptions

Within the U.S., the company determines the expected long-term rate of return on plan assets by performing a detailed analysis of key economic and market factors driving historical returns for each asset class and formulating a projected return based on factors in the current environment. Factors considered include, but are not limited to, inflation, real economic growth, interest rate yield, interest rate spreads, and other valuation measures and market metrics. The expected long-term rate of return for each asset class is then weighted based on the strategic asset allocation approved by the governing body for the plan. The company's historical experience with the pension fund asset performance is also considered. For non-U.S. plans, assumptions reflect economic assumptions applicable to each country.

In the U.S., Corteva calculates service costs and interest costs by applying individual spot rates from a yield curve (based on high-quality corporate bond yields) to the separate expected cash flows components of service cost and interest cost. Service cost and interest cost for all other plans are determined on the basis of the single equivalent discount rates derived in determining those plan obligations.

The discount rates utilized to measure the pension and other post employment benefit obligations are based on the yield on high-quality corporate fixed income investments at the measurement date. Future expected actuarially determined cash flows are individually discounted at the spot rates under the Aon AA_Above Median yield curve (based on high-quality corporate bond yields) to arrive at the plan’s obligations as of the measurement date. For non-U.S. benefit plans, historically the company utilized prevailing long-term high quality corporate bond indices to determine the discount rate, applicable to each country, at the measurement date.

The company adopts the most recently published mortality tables and mortality improvement scale released by the Society of Actuaries in measuring its U.S. pension and other post employment benefit obligations. The effect of these adoptions is amortized into net periodic benefit cost for the years following the adoption.

Plan Assets

All pension plan assets in the U.S. are invested through a single master trust fund. The strategic asset allocation for this trust fund is approved by the Pension Investment Committee. The general principles guiding U.S. pension asset investment policies are those embodied in the Employee Retirement Income Security Act of 1974 ("ERISA"). These principles include discharging Corteva's investment responsibilities for the exclusive benefit of plan participants and in accordance with the "prudent expert" standard and other ERISA rules and regulations. Corteva establishes strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes with the aim of achieving a prudent balance between return and risk. Strategic asset allocations in other countries are selected in accordance with the laws and practices of those countries. Where appropriate, asset liability studies are utilized in this process. U.S. plan assets are managed by investment professionals employed by Corteva. The remaining assets are managed by professional investment firms unrelated to the company. Corteva's pension investment professionals have discretion to manage the assets within established asset allocation ranges approved by the Pension Investment Committee. Additionally, pension trust funds are permitted to enter into certain contractual arrangements generally described as "derivatives." Derivatives are primarily used to reduce specific market risks, hedge currency and adjust portfolio duration and asset allocation in a cost-effective manner.

The weighted-average target allocation for plan assets of the company's pension plans is summarized as follows:


Target Allocation for Plan Assets	December 31, 2021		December 31, 2020
Asset Category
U.S. equity securities	11	%	20	%
Non-U.S. equity securities	11		16
Fixed income securities	58		51
Hedge funds	2		2
Private market securities	8		6
Real estate	5		4
Cash and cash equivalents	5		1
Total	100	%	100	%

U.S. equity investments are primarily large-cap companies. Global equity securities include varying market capitalization levels. Global fixed income investments include corporate-issued, government-issued and asset-backed securities. Corporate debt investments include a range of credit risk and industry diversification. U.S. fixed income investments are weighted heavier than non-U.S. fixed income securities. Other investments include cash and cash equivalents, hedge funds, real estate and private market securities such as interests in private equity and venture capital partnerships.

Fair value calculations may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

For pension plan assets classified as Level 1 measurements (measured using quoted prices in active markets), total fair value is either the price of the most recent trade at the time of the market close or the official close price, as defined by the exchange on which the asset is most actively traded on the last trading day of the period, multiplied by the number of units held without consideration of transaction costs.

For pension plan assets classified as Level 2 measurements, where the security is frequently traded in less active markets, fair value is based on the closing price at the end of the period; where the security is less frequently traded, fair value is based on the price a dealer would pay for the security or similar securities, adjusted for any terms specific to that asset or liability. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance and quality checks. For derivative assets and liabilities, standard industry models are used to calculate the fair value of the various financial instruments based on significant observable market inputs, such as foreign exchange rates, commodity prices, swap rates, interest rates and implied volatilities obtained from various market sources.

For pension plan assets classified as Level 3 measurements, total fair value is based on significant unobservable inputs including assumptions where there is little, if any, market activity for the investment. Investment managers, fund managers, or investment contract issuers provide valuations of the investment on a monthly or quarterly basis. These valuations are reviewed for reasonableness based on applicable sector, benchmark and company performance. Adjustments to valuations are made where appropriate. Where available, audited financial statements are obtained and reviewed for the investments as support for the manager’s investment valuation.

The tables below present the fair values of the company's pension assets by level within the fair value hierarchy, as described in Note 2 - Summary of Significant Accounting Policies:

Trust Assets

EID entered into a trust agreement in 2013 (as amended and restated in 2017) that established and requires EID to fund the Trust for cash obligations under certain non-qualified benefit and deferred compensation plans upon a change in control event as defined in the Trust agreement. Under the Trust agreement, the consummation of the Merger was a change in control event. As a result, in November 2017, EID contributed $571 million to the Trust. At the Separation, Corteva transferred $39 million to DuPont. During the years ended December 31, 2021 and 2020, $43 million and $65 million, respectively, was distributed to EID according to the Trust agreement, and at December 31, 2021 and 2020, the balance in the Trust was $304 million and $347 million, respectively. The Trust Assets are classified as current restricted cash equivalents and included within other current assets in the Consolidated Balance Sheets. See Note 9 - Supplementary Information, to the Consolidated Financial Statements, for further information.

Defined Contribution Plans

Corteva provides defined contribution benefits to its employees. The most significant is the U.S. Retirement Savings Plan ("the Plan"), which covers almost all of the U.S. full-service employees. This Plan includes a non-leveraged Employee Stock Ownership Plan ("ESOP"). Employees are not required to participate in the ESOP and those who do are free to diversify out of the ESOP. The purpose of the Plan is to provide retirement savings benefits for employees and to provide employees an opportunity to become stockholders of the company. The Plan is a tax qualified contributory profit sharing plan, with cash or deferred arrangement and any eligible employee of Corteva may participate. Currently, Corteva contributes 100 percent of the first 6 percent of the employee's contribution election and also contributes 3 percent of each eligible employee's eligible compensation regardless of the employee's contribution.

GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill

The following table summarizes changes in the carrying amount of goodwill by segment for the years ended December 31, 2021 and 2020, respectively.


(In millions)	Crop Protection		Seed		Total
Balance as of December 31, 2019	$	4,743	$	5,486	$	10,229
Currency translation adjustment	31		38		69

Other goodwill adjustments and acquisitions2	—		(2)		(2)
Balance as of December 31, 2021	$	4,672	$	5,435	$	10,107

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

2.Consists of the goodwill included in the sale of a business in the seed 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.

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 2021 and 2020. As of December 31, 2021, accumulated impairment losses on goodwill were $4,503 million.

Other Intangible Assets

The gross carrying amounts and accumulated amortization of other intangible assets by major class are as follows:


(In millions)	December 31, 2021						December 31, 2020

Total	$	12,605	$	(2,561)	$	10,044	$	12,609	$	(1,862)	$	10,747

1.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.

2.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 suggested that the fair value was 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.

The aggregate pre-tax amortization expense from continuing operations for definite-lived intangible assets was $722 million, $682 million, and $475 million, for the year ended December 31, 2021, December 31, 2020, and December 31, 2019, respectively.

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


(In millions)
2022	$	700
2023	$	620
2024	$	606
2025	$	569

[1]	In connection with the company's 2021 internal legal entity restructuring, the company reduced various state net operating loss carryforwards and corresponding full valuation allowances by $61 million. There was no impact on the statement of operations. During the year ended December 31, 2020, the company established a $19 million state tax valuation allowance in the U.S. based on a change in judgement about the realizability of a deferred tax asset.
[2]	Primarily related to the realization of recorded tax benefits on tax loss and credit carryforwards from operations in the United States, Brazil, and Spain.
[3]	Prior year classifications in property and other accruals and reserves have been adjusted from their previous presentation. Adjustments did not impact the amount of the net deferred tax asset (liability) recorded in the Consolidated Balance Sheets.

Stock-Based Compensation

Dec. 31, 2021

Share-based Payment Arrangement [Abstract]

Share-based Payment Arrangement [Text Block]

STOCK-BASED COMPENSATION

Prior to the Corteva Distribution, Corteva employees held equity awards, including stock options, share appreciation rights (“SARs”), restricted stock units (“RSUs”) and performance-based restricted stock units (“PSUs”), which were denominated in DowDuPont common stock and, in some cases, in Dow Inc. common stock, and which had originally been issued under the DuPont Equity and Incentive Plan ("EIP"), the Dow Chemical Company 2012 Stock Incentive Plan or the Dow Chemical Company 1988 Award and Option Plan.

As discussed in Note 18 - Commitment and Contingent Liabilities, on April 1, 2019 the company entered into an employee matters agreement (the "EMA") with DuPont and Dow 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. With some exceptions, the EMA provides for the equitable adjustment of existing equity incentive compensation awards denominated in the common stock of DowDuPont to reflect the occurrence of the Distributions.

In connection with the Separation on June 1, 2019, outstanding DowDuPont-denominated stock options, SARs, RSU and PSU awards were converted into Corteva-denominated awards under the “Employer Method,” or into both DuPont-denominated awards and Corteva-denominated awards under the “Shareholder Method,” using a formula designed to preserve the intrinsic value of the awards immediately prior to and subsequent to the Corteva Separation. The awards have the same terms and conditions under the applicable plans and award agreements prior to the Separation transactions. The conversions of equity awards did not have a material impact to the company’s consolidated financial statements.

On June 1, 2019 (“Adoption Date”), in connection with the Separation, the Omnibus Incentive Plan (the "OIP") became effective. Under the OIP, the company may grant incentive awards, including stock options (both “incentive stock options” and nonqualified stock options), share appreciation rights, restricted shares, restricted stock units, other share-based awards and cash awards, to its and its subsidiaries’ eligible employees, non-employee directors, independent contractors and consultants following the Separation until the tenth anniversary of the Adoption Date, subject to an aggregate limit and annual individual limits. Under the OIP, the maximum number of shares reserved for the grant or settlement of awards is 20 million shares, excluding shares underlying certain exempt awards, such as the awards converted to Corteva-denominated awards pursuant to the Separation. At December 31, 2021, approximately 12 million shares were authorized for future grants under the OIP. The company generally satisfies stock option exercises and the vesting of RSUs and PSUs with newly issued shares of Corteva common stock, although RSU awards granted under Historical Dow plans in certain countries are settled in cash.

The compensation committee determines the long-term incentive mix, including stock options, RSUs and PSUs and may authorize new grants annually. The company estimates expected forfeitures.

The total stock-based compensation cost included in income (loss) from continuing operations before income taxes within the Consolidated Statement of Operations was $79 million, $73 million, and $84 million for the years ended December 31, 2021, 2020 and 2019, respectively. The income tax benefits related to stock-based compensation arrangements were $(15) million, $(15) million, and $(17) million for the years ended December 31, 2021, 2020 and 2019, respectively.

Stock Options

The exercise price of shares subject to option is equal to the market price of the company's stock on the date of grant. All options vest serially over a period of three years. Stock option awards granted under the OIP between June 2019 and 2020 expire 10 years after the grant date. Stock option awards granted under the EIP (previous plan) between 2014 and 2015 expire seven years after the grant date and options granted between 2016 and May 2019 expire 10 years after the grant date. Stock option awards granted under the Historical Dow plans subsequent to 2010 expire 10 years after the grant date.

To measure the fair value of the awards on the date of grant, the company used the Black-Scholes option pricing model and the assumptions set forth in the below table. Under the OIP, the weighted-average grant-date fair value of options granted for the years ended December 31, 2021 and 2020 was $11.77 and $6.06, respectively. Under the EIP, the weighted-average grant-date fair value of options granted for the years ended December 31, 2019 was $7.29.


Weighted-Average Assumptions	OIP				EIP
	For the year ended December 31, 2021		For the year ended December 31, 2020		For the year ended December 31, 2019
Dividend yield	1.14	%	1.67	%	1.55	%
Expected volatility	29.44	%	23.14	%	19.80	%
Risk-free interest rate	1.0	%	1.3	%	2.4	%
Expected life of stock options granted during period (years)	6.0		6.0		6.1

Under the OIP, the company determined the dividend yield by dividing the annualized dividend on Corteva’ s Common Stock by the option exercise price. A historical daily measurement of volatility is determined based on the expected life of the option granted. For the years ended December 31, 2021 and 2020, the measurement of volatility is based on the average volatility of eight of Corteva's peer companies. Corteva's peer volatility is based on the historical volatility of each business respectively. The risk-free interest rate is determined by reference to the yield on an outstanding U.S. Treasury note with a term equal to the expected life of the option granted. Expected life is determined by utilizing the simplified method for estimating expected term as referenced under ASC 718 – Share based Payments.

Under the EIP, the company determined the dividend yield by dividing the annualized dividend on DowDuPont's Common Stock by the option exercise price.

A historical daily measurement of volatility is determined based on the expected life of the option granted. For the year ended December 31, 2019, the measurement of volatility is based on weighted average of the individual peer volatilities of DuPont and Corteva based on the size of each business respectively. DuPont and Corteva peer volatility are based on a 50/50 blend of historical volatility and implied volatility. Both volatility measures are based on the average of five peer companies for DuPont and eight peer companies for Corteva.

The risk-free interest rate is determined by reference to the yield on an outstanding U.S. Treasury note with a term equal to the expected life of the option granted. Expected life is determined by reference to the company's historical experience.

The following table summarizes stock option activity for year ended December 31, 2021 under the OIP:


Stock Options	For the Year Ended December 31, 2021
	Number of Shares (in thousands)	Weighted Average Exercise Price (per share)		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)
Outstanding at January 1, 2021	8,998	$	34.21	5.27	$	50,077

Granted	849	45.37
Exercised	(3,206)	32.44
Forfeited/Expired	(218)	33.39

Outstanding at December 31, 2021	6,423	$	36.65	5.69	$	68,219
Exercisable at December 31, 2021	4,739	$	36.15	4.76	$	52,726

The aggregate intrinsic values in the table above represent the total pre-tax intrinsic value (the difference between the closing stock price on the last trading day of the December 31, 2021 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their in-the-money options at period end. Under the OIP, the total intrinsic value of options exercised for the years ended December 31, 2021 and 2020 were $43 million, and $21 million, respectively. The company recognized tax benefits from options exercised for the years ended December 31, 2021 and 2020 of $(8) million and $(4) million, respectively.

Under the EIP, the total intrinsic value of options exercised for the year ended December 31, 2019 was $16 million. The company recognized tax benefits from options exercised for the year ended December 31, 2019 of $(3) million.

As of December 31, 2021, $4 million of total unrecognized pre-tax compensation expense related to nonvested stock options is expected to be recognized over a weighted-average period of about 1.20 years.

Restricted Stock Units and Performance Share Units

RSUs granted under the EIP serially vest over 3 years. RSUs granted under the Historical Dow plans vest after a designated period, generally 1 year to 3 years. RSUs granted under the OIP serially vest over 3 years. Upon vesting, these RSUs convert one-for-one to Corteva Common Stock. A retirement-eligible employee retains any granted awards upon retirement provided the employee has rendered at least six months of service following the grant date. Additional RSUs are also granted periodically to key senior management employees. These RSUs generally vest over periods ranging from 3 years to 5 years. The fair value of all stock-settled RSUs is based upon the market price of the underlying common stock as of the grant date.

The company grants PSUs to senior leadership. In 2021, there were 343,632 PSUs granted. Vesting for PSUs granted in 2021 and 2020 is partially based on the realization of the Company’s improvement of its Return on Invested Capital (“ROIC”) and Operating Earnings Per Share (EPS) during the Performance Period. Vesting for PSUs granted in 2019 is partially based on the realization of the Company’s improvement of its Return on Invested Capital (“ROIC”) and Operating EBITDA during the Performance Period. Performance and payouts are determined independently for each metric. The actual award, delivered in Corteva Common Stock, can range from zero percent to 200 percent of the original grant. The weighted-average grant date fair value of the PSUs granted in 2021 of $45.37 was based upon the market price of the underlying common stock as of the grant date.

Nonvested awards of RSUs and PSUs are shown below.


RSUs & PSUs	For the Year Ended December 31, 2021
	Number of Shares (in thousands)	Weighted Average Grant Date Fair Value (per share)
Nonvested at January 1, 2021	5,883	$	31.54
Granted	1,536	$	45.30
Vested	(1,583)	$	35.59
Forfeited	(234)	$	32.99
Nonvested at December 31, 2021	5,602	$	34.11

The total fair value of stock units vested under the OIP for the years ended December 31, 2021 and 2020 was $56 million and $49 million, respectively. The weighted-average grant-date fair value of stock units granted under the OIP for the years ended December 31, 2021 and 2020 was $45.30 and $31.15, respectively.

The total fair value of stock units vested under the EIP during the years ended December 31, 2019 was $79 million. The weighted-average grant-date fair value of stock units granted under the EIP for the year ended December 31, 2019 was $52.19.

As of December 31, 2021, $45 million of total unrecognized pre-tax compensation expense related to RSUs and PSUs is expected to be recognized over a weighted average period of 1.13 years.

Weighted-average common shares - diluted	741.6	751.2	749.5
Potential shares of common stock excluded from EPS calculations3	2.8	9.4	14.4

1.Share amounts for all periods prior to the Corteva Distribution were based on 748.8 million shares of Corteva, Inc. common stock distributed to holders of DowDuPont's common stock on June 1, 2019, plus 0.6 million of additional shares in which accelerated vesting conditions have been met.

2.Diluted earnings (loss) per share considers the impact of potentially dilutive securities except in periods in which there is a loss because the inclusion of the potential common shares would have an anti-dilutive effect.

3.These outstanding potential shares of common stock relating to stock options, restricted stock units and performance-based restricted stock units were excluded from the calculation of diluted earnings (loss) per share because (i) the effect of including stock options and restricted stock units would have been anti-dilutive; and (ii) the performance metrics have not yet been achieved for the outstanding potential shares relating to performance-based restricted stock units, which are deemed to be contingently issuable.

Financial Instruments Disclosure [Text Block]

FINANCIAL INSTRUMENTS

At December 31, 2021 and 2020, the company had $3,400 million and $2,511 million, respectively, of held-to-maturity securities (primarily time deposits and money market funds) classified as cash equivalents, as these securities had maturities of three months or less at the time of purchase; and $86 million and $43 million at December 31, 2021 and 2020, respectively, of held-to-maturity securities (primarily time deposits) classified as marketable securities as these securities had maturities of more than three months to less than one year at the time of purchase. The company’s investments in held-to-maturity securities are held at amortized cost, which approximates fair value. Additionally, at December 31, 2020, the company had $226 million of available-for-sale securities (see below "Debt Securities" for further discussion). The above noted securities are included in cash and cash equivalents, marketable securities, and other current assets in the Consolidated Balance Sheets.

Derivative Instruments

Objectives and Strategies for Holding Derivative Instruments

In the ordinary course of business, the company enters into contractual arrangements (derivatives) to reduce its exposure to foreign currency and commodity price risks. The company has established a variety of derivative programs to be utilized for financial risk management. These programs reflect varying levels of exposure coverage and time horizons based on an assessment of risk.

Derivative programs have procedures and controls and are approved by the Corporate Financial Risk Management Committee, consistent with the company's financial risk management policies and guidelines. Derivative instruments used are forwards, options, futures and swaps. The company has not designated any non-derivatives as hedging instruments.

The company's financial risk management procedures also address counterparty credit approval, limits and routine exposure monitoring and reporting. The counterparties to these contractual arrangements are major financial institutions and major commodity exchanges, and multinational grain exporters. The company is exposed to credit loss in the event of nonperformance by these counterparties. The company utilizes collateral support annex agreements with certain counterparties to limit its exposure to credit losses. The company anticipates performance by counterparties to these contracts and therefore no material loss is expected. Market and counterparty credit risks associated with these instruments are regularly reported to management.

The notional amounts of the company's derivative instruments were as follows:


Notional Amounts (In millions)	December 31, 2021		December 31, 2020
Derivatives designated as hedging instruments:
Foreign currency contracts	$	1,252	$	1,164
Commodity contracts	$	845	$	383
Derivatives not designated as hedging instruments:
Foreign currency contracts	$	103	$	647
Commodity contracts	$	4	$	—

Foreign Currency Risk

The company's objective in managing exposure to foreign currency fluctuations is to reduce earnings and cash flow volatility associated with foreign currency rate changes and to mitigate the exposure of certain investments in foreign subsidiaries against

changes in the Euro/USD exchange rate. Accordingly, the company enters into various contracts that change in value as foreign exchange rates change to protect the value of its existing foreign currency-denominated assets, liabilities, commitments, investments and cash flows.

The company uses foreign exchange contracts to offset its net exposures, by currency, related to the foreign currency denominated monetary assets and liabilities of its operations. The primary business objective of this hedging program is to maintain an approximately balanced position in foreign currencies so that exchange gains and losses resulting from exchange rate changes, after related tax effects, are minimized. The company also uses foreign currency exchange contracts to offset a portion of the company's exposure to certain forecasted transactions as well as the translation of foreign currency-denominated earnings. The company also uses commodity contracts to offset risks associated with foreign currency devaluation in certain

countries.

Commodity Price Risk

Commodity price risk management programs serve to reduce exposure to price fluctuations on purchases of inventory such as corn and soybeans. The company enters into over-the-counter and exchange-traded derivative commodity instruments to hedge the commodity price risk associated with agricultural commodity exposures.

Derivatives Designated as Cash Flow Hedges

Commodity Contracts

The company enters into over-the-counter and exchange-traded derivative commodity instruments, including options, futures and swaps, to hedge the commodity price risk associated with agriculture commodity exposures.

While each risk management program has a different time maturity period, most programs currently do not extend beyond the next two years. Cash flow hedge results are reclassified into earnings during the same period in which the related exposure impacts earnings. Reclassifications are made sooner if it appears that a forecasted transaction is probable of not occurring.

The following table summarizes the after-tax effect of commodity contract cash flow hedges on accumulated other comprehensive loss:


	For the Year Ended December 31,
(In millions)	2021		2020		2019
Beginning balance	$	(16)	$	2	$	(26)
Additions and revaluations of derivatives designated as cash flow hedges	92		(44)		16
Clearance of hedge results to earnings	(29)		26		12
Ending balance	$	47	$	(16)	$	2

At December 31, 2021, an after-tax net gain of $36 million is expected to be reclassified from accumulated other comprehensive loss into earnings over the next twelve months.

Foreign Currency Contracts

The company enters into forward contracts to hedge the foreign currency risk associated with forecasted transactions within certain foreign subsidiaries.

The following table summarizes the after-tax effect of foreign currency cash flow hedges on accumulated other comprehensive

loss:


(In millions)	For the Year Ended December 31, 2021		For the Year Ended December 31, 2020
(In millions)	For the Year Ended December 31, 2021		For the Year Ended December 31, 2020

Additions and revaluations of derivatives designated as cash flow hedges	24		(3)
Clearance of hedges results to earnings	25		(14)
Ending balance	$	32	$	(17)

At December 31, 2021, an after-tax net gain of $32 million is expected to be reclassified from accumulated other comprehensive loss into earnings over the next twelve months.

Derivatives Designated as Net Investment Hedges

Foreign Currency Contracts

The company has designated €450 million of forward contracts to exchange EUR as net investment hedges. The purpose of these forward contracts is to mitigate FX exposure related to a portion of the company’s Euro net investments in certain foreign subsidiaries against changes in Euro/USD exchange rates. These hedges will expire and be settled in 2023, unless terminated early at the discretion of the company.

The company elected to apply the spot method in testing for effectiveness of the hedging relationship.

Derivatives not Designated in Hedging Relationships

Foreign Currency Contracts

The company uses foreign exchange contracts to reduce its net exposure, by currency, related to foreign currency-denominated monetary assets and liabilities of its operations so that exchange gains and losses resulting from exchange rate changes are minimized. The netting of such exposures precludes the use of hedge accounting; however, the required revaluation of the forward contracts and the associated foreign currency-denominated monetary assets and liabilities intends to achieve a minimal earnings impact, after taxes. The company also uses foreign currency exchange contracts to offset a portion of the company’s exposure to the translation of certain foreign currency-denominated earnings so that gains and losses on the contracts offset changes in the USD value of the related foreign currency-denominated earnings over the relevant aggregate period.

Commodity Contracts

The company utilizes options, futures and swaps that are not designated as hedging instruments to reduce exposure to commodity price fluctuations on purchases of inventory such as corn and soybeans. The company uses forward agreements,

with durations less than one year, to buy and sell USD priced commodities in order to reduce its exposure to currency devaluation for a portion of its local currency cash balances. Counterparties to the forward sales agreements are multinational grain exporters and subject to the company’s financial risk management procedures.

Asset and liability derivatives subject to an enforceable master netting arrangement with the same counterparty are presented on a net basis in the Consolidated Balance Sheets. The presentation of the company's derivative assets and liabilities is as follows:

Debt Securities

The estimated fair value of the available-for-sale securities as of December 31, 2020 was determined using Level 1 inputs within the fair value hierarchy. Level 1 measurements were based on quoted market prices in active markets for identical assets and liabilities. The available-for-sale securities at of December 31, 2020 are held by certain foreign subsidiaries in which the USD is not the functional currency. The fluctuations in foreign exchange are recorded in accumulated other comprehensive loss within the Consolidated Statements of Equity. These fluctuations are subsequently reclassified from accumulated other comprehensive income (loss) to earnings in the period in which the marketable securities are sold and the gains and losses on these securities offset a portion of the foreign exchange fluctuations in earnings for the company.

The following table provides the investing results from available-for-sale securities for the year ended December 31,2021:

The cumulative translation adjustment losses for the year ended December 31, 2021 was primarily driven by the strengthening of the U.S. Dollar ("USD") against the European Euro ("EUR"), Swiss franc ("CHF") and Turkish Lira (“TRY”). The cumulative translation adjustment losses for the year ended December 31, 2020 was primarily driven by the strengthening of the U.S. Dollar ("USD") against the Brazilian Real ("BRL"), partially offset by the weakening of the U.S. Dollar against the Swiss franc ("CHF") and European Euro ("EUR").

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. When the company performs shipping and handling activities after the transfer of control to the customer (e.g., when control transfers prior to or at shipment), these are considered fulfillment activities, and accordingly, the costs are accrued when the related revenue is recognized. 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 primarily utilize the expected value method based on historical experience. 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 $123 million and $115 million at December 31, 2021 and December 31, 2020, respectively. The company expects revenue to be recognized for the remaining performance obligations evenly over the period of 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 conditional 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.

Recent Accounting Guidance	12 Months Ended
Recent Accounting Guidance	Dec. 31, 2021
Accounting Changes and Error Corrections [Abstract]
Recent Accounting Guidance	RECENT ACCOUNTING GUIDANCE Recently Adopted Accounting Guidance 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. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which is 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 interim periods within those fiscal years, beginning after December 15, 2020. The company adopted this guidance on January 1, 2021 and it 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, 2021 In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance, which requires business entities to disclose transactions with a governmental entity for which a grant or contribution accounting model is used in recognizing and measuring such transactions. This standard is effective for fiscal years beginning after December 15, 2021, and early adoption is permitted. The company is currently evaluating the impact of adopting this guidance.

The entire disclosure for change in accounting principle. Includes, but is not limited to, nature, reason, and method of adopting amendment to accounting standards or other change in accounting principle.

Leases [Abstract]

Leases of Lessee Disclosure [Text Block]

LEASES

The company has operating and finance leases for real estate, transportation, certain machinery and equipment, and information technology assets. The company’s leases have remaining lease terms of 1 to 50 years. For purposes of calculating operating lease liabilities, lease terms may be deemed to include options to extend the lease when it is reasonably certain that the company will exercise that option. Some leasing arrangements require variable payments that are dependent on usage, output, or may vary for other reasons, such as insurance and tax payments. The variable lease payments are not presented as part of the initial ROU asset or lease liability.

Certain of the company's leases include residual value guarantees. These residual value guarantees are based on a percentage of the lessor's asset acquisition price and the amount of such guarantee declines over the course of the lease term. The portion of residual value guarantees that are probable of payment are included in the related lease liability. At December 31, 2021, the company has future maximum payments for residual value guarantees in operating leases of $193 million with final expirations through 2028. The company's lease agreements do not contain any material restrictive covenants. The components of lease cost are as follows:

Recent Accounting Guidance Recent Accounting Guidance (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Recent Accounting Guidance	RECENT ACCOUNTING GUIDANCE Recently Adopted Accounting Guidance 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. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which is 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 interim periods within those fiscal years, beginning after December 15, 2020. The company adopted this guidance on January 1, 2021 and it 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, 2021 In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance, which requires business entities to disclose transactions with a governmental entity for which a grant or contribution accounting model is used in recognizing and measuring such transactions. This standard is effective for fiscal years beginning after December 15, 2021, and early adoption is permitted. The company is currently evaluating the impact of adopting this guidance.

Receivables [Abstract]

ACCOUNTS AND NOTES RECEIVABLE - NET


(In millions)	December 31, 2021		December 31, 2020
Accounts receivable – trade1	$	3,441	$	3,754
Notes receivable – trade1,2	120		163
Other3	1,250		1,009
Total accounts and notes receivable - net	$	4,811	$	4,926

1.Accounts receivable – trade and notes receivable – trade are net of allowances of $210 million and $208 million at December 31, 2021 and December 31, 2020, respectively. Allowances are equal to the estimated uncollectible amounts and are based on the expected credit losses and were developed using a loss-rate method.

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, 2021 and 2020, 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 $104 million and $106 million as of December 31, 2021 and 2020, respectively.

Accounts and notes receivable are carried at the expected amount to be collected, which approximates fair value. The company establishes the allowance for doubtful receivables using a loss-rate method where the loss rate is developed using past events, historical experience, current conditions and forecasts that affect the collectability of the financial assets.

The following table summarizes changes in the allowance for doubtful receivables for the year ended December 31, 2021 and 2020, respectively:


(In millions)
2020
Balance at December 31, 2019	$	174
Net provision for credit losses1	52
Write-offs charged against allowance / other1	(18)
Balance at December 31, 2020	$	208

2021
Balance at December 31, 2020	$	208
Net provision for credit losses	1
Write-offs charged against allowance / other	1
Balance at December 31, 2021	$	210

1. Prior year classifications in the changes in the allowance for doubtful receivables have been adjusted from their previous presentation. Adjustments did not impact the amount of the provision or the allowance for doubtful receivables recorded in the Consolidated Statements of Operations or the Consolidated Balance Sheets.

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 $272 million, $255 million, and $328 million for the years ended December 31, 2021, 2020 and 2019, respectively. The trade receivables sold that remained outstanding under these agreements which include an element of recourse as of December 31, 2021 and December 31, 2020 were $166 million and $157 million, respectively. The net proceeds received were included in cash provided by (used for) 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 - net in the Consolidated Statements of Operations. The loss on sale of receivables were $54 million, $55 million, and $44 million for the years ended December 31, 2021, 2020 and 2019, respectively. See Note 18 - Commitments and Contingent Liabilities, to the Consolidated Financial Statements, for additional information on the company’s guarantees.

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	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. Intercompany balances and transactions with Historical EID and DAS have been eliminated.

Revenue from Contract with Customer [Abstract]
Revenue Recognition, Sales of Goods	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. When the company performs shipping and handling activities after the transfer of control to the customer (e.g., when control transfers prior to or at shipment), these are considered fulfillment activities, and accordingly, the costs are accrued when the related revenue is recognized. 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 primarily utilize the expected value method based on historical experience. 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.
Revenue Recognition, Services, Licensing Fees	Licenses of Intellectual PropertyCorteva 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.

Summary of Significant Accounting Policies

12 Months Ended

Dec. 31, 2021

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The company is also involved with certain joint ventures accounted for under the equity method of accounting that are variable interest entities ("VIEs"). The company is not the primary beneficiary, as the nature of the company's involvement with the VIEs does not provide it the power to direct the VIEs significant activities. Future events may require these VIEs to be consolidated if the company becomes the primary beneficiary. At December 31, 2021 and 2020, the maximum exposure to loss related to the nonconsolidated VIEs is not considered material to the Consolidated Financial Statements.

Use of Estimates in Financial Statement Preparation

The preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The company’s consolidated financial statements include amounts that are based on management’s best estimates and judgments. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash equivalents represent investments with maturities of three months or less from time of purchase. They are carried at cost plus accrued interest.

Restricted Cash Equivalents

Marketable Securities

Fair Value Measurements

The company uses the following valuation techniques to measure fair value for its assets and liabilities:


Level 1	–	Quoted market prices in active markets for identical assets or liabilities;

Level 2	–	Significant other observable inputs (e.g. quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs other than quoted prices that are observable such as interest rate and yield curves, and market-corroborated inputs);

Level 3	–	Unobservable inputs for the asset or liability, which are valued based on management's estimates of assumptions that market participants would use in pricing the asset or liability.

Foreign Currency Translation

Inventories

The company establishes an obsolescence reserve for inventory based upon quality considerations and assumptions about future demand and market conditions.

Cost of Goods Sold

Cost of goods sold primarily includes the cost of manufacture and delivery, ingredients or raw materials, direct salaries, wages and benefits and overhead, non-capitalizable costs associated with capital projects, royalties and other operational expenses. No amortization of intangibles is included within cost of goods sold.

Research and Development

Selling, General and Administrative Expenses

Selling, general and administrative expenses primarily include selling and marketing expenses, commissions, functional costs, and business management expenses.

Integration and Separation Costs

Litigation and Other Contingencies

Accruals for legal matters and other contingencies are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Legal costs, such as outside counsel fees and expenses, are charged to expense in the period incurred.

Severance Costs

Severance benefits are provided to employees under the company's ongoing benefit arrangements. Severance costs are accrued when management commits to a plan of termination and it becomes probable that employees will be entitled to benefits at amounts that can be reasonably estimated.
