Retirement Benefits [Abstract] |
Pension and Other Postretirement Benefits Disclosure [Text Block] | PENSION PLANS AND OTHER POST EMPLOYMENT BENEFITS The company offers various long-term benefits to its employees. Where permitted by applicable law, the company reserves the right to change, modify or discontinue the plans. As a result of the Merger, the company re-measured its pension and OPEB plans. The remeasurement of the company’s pension and OPEB plans is included in the fair value measurement of EID’s assets and liabilities as a result of the application of purchase accounting in connection with the Merger. In addition, net losses and prior service benefits recognized in accumulated other comprehensive income (loss) were eliminated. Historical Dow and EID did not merge their pension plans and OPEB plans as a result of the Merger. In connection with the Corteva Distribution and Internal Reorganization, the company retained the benefit obligations relating to EID's principal U.S. pension plan, several other U.S. and non-U.S. pension plans and OPEB. Corteva entered into an employee matters agreement with DuPont which provides that employees of DuPont no longer participate in the benefits sponsored or maintained by the company as of the date of the Corteva Distribution and transferred certain of EID's pension and OPEB obligations and associated assets to DuPont. As a result of the transfer at Separation, about $5.8 billion unfunded obligations of the pension and OPEB plans remained with Corteva, of which $319 million was supported by funding under the Trust agreement. Defined Benefit Pension Plans The company has both funded and unfunded noncontributory defined benefit pension plans covering a majority of the U.S. employees and employees in a number of other countries. The principal U.S. pension plan is the largest pension plan held by Corteva. Most employees hired on or after January 1, 2007 are not eligible to participate in the U.S. defined benefit pension plans. The benefits under these plans are based primarily on years of service and employees' pay near retirement. In November 2016, EID announced that it will freeze the pay and service amounts used to calculate pension benefits for active employees who participate in the U.S. pension plans on November 30, 2018. Therefore, as of November 30, 2018, employees participating in the U.S. pension plans no longer accrue additional benefits for future service and eligible compensation received. The company's funding policy is consistent with the funding requirements of federal laws and regulations. Pension coverage for employees of the company's non-U.S. consolidated subsidiaries is provided, to the extent deemed appropriate, through separate plans. Obligations under such plans are funded by depositing funds with trustees, covered by insurance contracts, or remain unfunded. The company made a discretionary contribution of $1,100 million in the third quarter of 2018 to its principal U.S. pension plan. The company made total contributions of $62 million, $121 million, and $214 million to its pension plans other than the principal U.S. pension plan for the years ended December 31, 2020, 2019 and 2018, respectively. Corteva expects to contribute approximately $47 million to its pension plans other than the principal U.S. pension plan in 2021. The company is evaluating potential discretionary contributions in 2021 to the principal U.S. pension plan, that could reduce a portion of the underfunded benefit obligation. Any discretionary contributions depend on various factors including market conditions and tax deductible limits. The weighted-average assumptions used to determine pension plan obligations for all pension plans are summarized in the table below:
Weighted-Average Assumptions used to Determine Benefit Obligations | December 31, 2020 | December 31, 2019
Discount rate | 2.44 | % | 3.20 | %
Rate of increase in future compensation levels | 2.54 | % | 2.60 | %
The weighted-average assumptions used to determine net periodic benefit costs for all pension plans are summarized in the table below:
Weighted-Average Assumptions used to Determine Net Periodic Benefit Cost | For the Year Ended December 31,
2020 | 2019 | 2018
Discount rate | 3.19 | % | 4.19 | % | 3.38 | %
Rate of increase in future compensation levels | 2.60 | % | 2.84 | % | 4.04 | %
Expected long-term rate of return on plan assets | 6.25 | % | 6.24 | % | 6.19 | %
After November 30, 2018 the rate of compensation increase in the above tables excludes U.S. pension plans since the employees who participate in the U.S. pension plans no longer accrue additional benefits for future service and eligible compensation as of that date. 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-retirement medical, dental and life insurance plans. The associated plans for retiree benefits are unfunded and the cost of premiums or approved claims is paid from company funds. 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. Effective January 1, 2022, the company will no longer provide retiree dental and life insurance benefits. In addition, Corteva’s portion of the cost of non-Medicare retiree medical coverage will no longer be adjusted for cost increases, resulting in Corteva’s cost to be capped at the level in effect as of December 31, 2021. 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. 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-61. 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 $207 million, $202 million, and $216 million for the years ended December 31, 2020, 2019 and 2018, respectively. Changes in cash requirements reflect the net impact of higher per capita health care costs, demographic changes, plan amendments and changes in participant premiums, co-pays and deductibles. In 2021, the company expects to contribute approximately $217 million for its OPEB plans. Beginning in 2022, expected future benefit payments are anticipated to decrease to approximately $140 million as a result of the OPEB plan amendment. 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, 2020 | December 31, 2019
Discount rate | 2.09 | % | 3.07 | %
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,
2020 | 2019 | 2018
Discount rate | 3.07 | % | 3.93 | % | 3.56 | %
Assumed Health Care Cost Trend Rates | December 31, 2020 | December 31, 2019
Health care cost trend rate assumed for next year | 7.00 | % | 7.20 | %
Rate to which the cost trend rate is assumed to decline (the ultimate health care trend rate)¹ | N/A | 5.00 | %
Year that the rate reached the ultimate health care cost trend rate¹ | N/A | 2028
1. Due to December 2020 plan changes, health care cost trend rates are no longer applicable to the Corteva portion of the cost, effective January 1, 2022. 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 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. Summarized information on the company's pension and other post employment benefit plans is as follows:

The significant loss related to the change in pension plan benefit obligations for the period ended December 31, 2020 is mainly due to a decrease in discount rates. The substantially lower OPEB benefit obligations for the period ended December 31, 2020 is due to the December 2020 OPEB plan amendment. The accumulated benefit obligation for all pensions plans was $21.6 billion and $21.0 billion at December 31, 2020 and 2019, respectively.

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, 2020 | December 31, 2019
Asset Category
U.S. equity securities | 20 | % | 20 | %
Non-U.S. equity securities | 16 |  | 16 |
Fixed income securities | 51 |  | 50 |
Hedge funds | 2 |  | 3 |
Private market securities | 6 |  | 6 |
Real estate | 4 |  | 3 |
Cash and cash equivalents | 1 |  | 2 |
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 year ended December 31, 2019, $62 million was distributed to EID according to the Trust agreement and at December 31, 2019, the balance in the Trust was $409 million. During the year ended December 31, 2020, $65 million was distributed to EID according to the Trust agreement and at December 31, 2020, the balance in the Trust was $347 million. 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. Corteva's contributions to the Plan were $94 million, $142 million, and $183 million for the years ended December 31, 2020, 2019 and 2018, respectively. Corteva's matching contributions vest immediately upon contribution. The 3 percent nonmatching company contribution vests after employees complete three years of service. In addition, Corteva made contributions to other defined contribution plans of $33 million, $46 million, and $82 million for the years ended December 31, 2020, 2019 and 2018, respectively. Included in Corteva's contributions are amounts related to discontinued operations of $73 million and $148 million, for the years ended December 31, 2019 and 2018, respectively.
