| Commitments and Contingencies Disclosure [Text Block] | COMMITMENTS AND CONTINGENT LIABILITIES Guarantees Indemnifications In connection with acquisitions and divestitures as of September 30, 2019 , the company has indemnified respective parties against certain liabilities that may arise in connection with these transactions and business activities prior to the completion of the transactions. The term of these indemnifications, which typically pertain to environmental, tax and product liabilities, is generally indefinite. In addition, the company indemnifies its duly elected or appointed directors and officers to the fullest extent permitted by Delaware law, against liabilities incurred as a result of their activities for the company, such as adverse judgments relating to litigation matters. If the indemnified party were to incur a liability or have a liability increase as a result of a successful claim, pursuant to the terms of the indemnification, the company would be required to reimburse the indemnified party. The maximum amount of potential future payments is generally unlimited. See pages 40 and 17 for additional information relating to the indemnification obligations under the Chemours Separation Agreement and the Corteva Separation Agreement. Obligations for Customers and Other Third Parties The company has directly guaranteed various debt obligations under agreements with third parties related to customers and other third parties. At September 30, 2019 , December 31, 2018 and September 30, 2018 , the company had directly guaranteed $80 million , $299 million , and $187 million , respectively, of such obligations. These amounts represent the maximum potential amount of future (undiscounted) payments that the company could be required to make under the guarantees in the event of default by the guaranteed party. Of the total maximum future payments at September 30, 2019 , $79 million had terms less than a year. The maximum future payments also include $11 million , $3 million , and $5 million of guarantees related to the various factoring agreements that the company enters into with its customer to sell its trade receivables at September 30, 2019 , December 31, 2018 and September 30, 2018 , respectively. See Note 12 - Accounts and Notes Receivable, Net, for additional information. The maximum future payments include agreements with lenders to establish programs that provide financing for select customers. The terms of the guarantees are equivalent to the terms of the customer loans that are primarily made to finance customer invoices. The total accounts receivable balance outstanding on these agreements was $596 million , $14 million and $282 million at September 30, 2019 , December 31, 2018 and September 30, 2018 , respectively. The company assesses the payment/performance risk by assigning default rates based on the duration of the guarantees. These default rates are assigned based on the external credit rating of the counterparty or through internal credit analysis and historical default history for counterparties that do not have published credit ratings. For counterparties without an external rating or available credit history, a cumulative average default rate is used. Litigation The company is subject to various legal proceedings, including, but not limited to, product liability, intellectual property, antitrust, commercial, property damage, personal injury, environmental and regulatory matters arising out of the normal course of its current businesses or legacy EID businesses unrelated to Corteva’s current businesses but allocated to Corteva as part of the separation of Corteva from DuPont. It is not possible to predict the outcome of these various proceedings. Although considerable uncertainty exists, management does not anticipate that the ultimate disposition of these matters will have a material adverse effect on the company's results of operations, consolidated financial position or liquidity. However, the ultimate liabilities could be material to results of operations and the cash flows in the period recognized. Indemnifications under Separation Agreements The company has entered into various agreements where the company is indemnified for certain liabilities. In connection with the recognition of liabilities related to these matters, the company records an indemnification asset when recovery is deemed probable. See Note 5 - Divestitures and Other Transactions, for additional information related to indemnifications. Chemours/Performance Chemicals On July 1, 2015, EID completed the separation of its Performance Chemicals segment through the spin-off of all of the issued and outstanding stock of The Chemours Company (the "Chemours Separation"). In connection with the Chemours Separation, EID and The Chemours Company ("Chemours") entered into a Separation Agreement (the "Chemours Separation Agreement"). Pursuant to the Chemours Separation Agreement and the amendment to the Chemours Separation Agreement, Chemours indemnifies the company against certain litigation, environmental, workers' compensation and other liabilities that arose prior to the distribution. The term of this indemnification is generally indefinite and includes defense costs and expenses, as well as monetary and non-monetary settlements and judgments. Concurrent with the MDL Settlement (as discussed below), EID and Chemours amended the Chemours Separation Agreement to provide for a limited sharing of potential future PFOA liabilities for five years , which began on July 6, 2017. During the five years , Chemours will annually pay the first $25 million of future PFOA liabilities and, if that amount is exceeded, EID will pay any excess amount up to the next $25 million , with Chemours annually bearing any excess liabilities above that amount. At the end of the five years , this limited sharing agreement will expire, and Chemours’ indemnification obligations under the Chemours Separation Agreement will continue unchanged. As part of this amendment, Chemours also agreed that it would not contest its liability for PFOA liabilities on the basis of certain ostensible defenses it had previously raised, including defenses relating to punitive damages, and would waive any such defenses with respect to PFOA liabilities. Chemours has, however, retained defenses as to whether any particular PFOA claim is within the scope of the indemnification provisions of the Chemours Separation Agreement. There have been no charges incurred by the company under this amendment through September 30, 2019 . On May 13, 2019, Chemours filed a complaint in the Delaware Court of Chancery against DuPont, Corteva, and EID alleging, among other things, that the litigation and environmental liabilities allocated to Chemours under the Chemours Separation Agreement were underestimated and asking that the Court either limit the amount of Chemours’ indemnification obligations or, alternatively, order the return of the $3.91 billion dividend Chemours paid to EID prior to its separation. On June 3, 2019, the defendants moved to dismiss the complaint on the grounds that the Chemours Separation Agreement requires arbitration of all disputes relating to that agreement. On October 18, 2019, Chemours filed its brief objecting to the motion to dismiss on the grounds that the arbitration provisions of the Chemours Separation Agreement were unconscionable, and therefore are unenforceable. The company believes the probability of liability with respect to Chemours' suit to be remote, and the defendants continue to vigorously defend the company's rights, including full indemnity rights as set forth in the Chemours Separation Agreement. For additional information regarding environmental indemnification, see discussion below on page 44. At September 30, 2019 , the indemnification assets pursuant to the Chemours Separation Agreement are $67 million within accounts and notes receivable - net and $290 million within other assets along with the corresponding liabilities of $67 million within accrued and other current liabilities and $290 million within other noncurrent obligations in the interim Condensed Consolidated Balance Sheet. Corteva Separation Agreement On April 1, 2019, in connection with the Dow Distribution, Corteva, DuPont and Dow entered into the Corteva Separation Agreement, the Tax Matters Agreement, the Employee Matters Agreement, and certain other agreements (collectively, the “Corteva Separation Agreements”). The Corteva Separation Agreements allocate among Corteva, DuPont and Dow certain liabilities and obligations among the parties and provides for indemnification obligation among the parties. Under the Corteva Separation Agreements, DuPont will indemnify Corteva against certain litigation, environmental, workers' compensation and other liabilities that arose prior to the Corteva Distribution and (ii) Dow indemnifies Corteva against certain litigation and other liabilities that relate to the Historical Dow business, but were transferred over as part of DAS, and Corteva indemnifies DuPont and Dow for certain liabilities. The term of this indemnification is generally indefinite with exceptions, and includes defense costs and expenses, as well as monetary and non-monetary settlements and judgments. See Note 1 - Background and Basis of Presentation, and Note 5 - Divestitures and Other Transactions, for additional information relating to the Separation. DuPont Under the Corteva Separation Agreement, certain legacy EID liabilities from discontinued and/or divested operations and businesses of EID (including Performance Chemicals) (a “stray liability”) were allocated to Corteva or DuPont. For those stray liabilities allocated to Corteva (which may include a specified amount of liability associated with that liability), Corteva is responsible for liabilities in an amount up to that specified amount plus an additional $200 million and, for those stray liabilities allocated to DuPont (which may include a specified amount of liability associated with that liability), DuPont is responsible for liabilities up to a specified amount plus an additional $200 million . Once each company has met the $200 million threshold, Corteva and DuPont will share future liabilities proportionally on the basis of 29% and 71% , respectively; provided, however, that for PFAS, DuPont will manage such liabilities with Corteva and DuPont sharing the costs on a 50% - 50% basis starting from $1 and up to $300 million (with such amount, up to $150 million , to be credited to each company’s $200 million threshold) and once the $300 million threshold is met, then the companies will share proportionally on the basis of 29% and 71% respectively, subject to a $1 million de minimis requirement. Litigation related to legacy EID businesses unrelated to Corteva’s current businesses PFAS, PFOA, PFOS and Other Related Liabilities For purposes of this report, the term PFOA means collectively perfluorooctanoic acid and its salts, including the ammonium salt and does not distinguish between the two forms, and PFAS, which means per- and polyfluoroalkyl substances, including PFOA, PFOS (perfluorooctanesulfonic acid), GenX and other perfluorinated chemicals and compounds ("PFCs"). EID is a party to various legal proceedings relating to the use of PFOA by its former Performance Chemicals segment. While it is reasonably possible that the company could incur liabilities related to PFOA, any such liabilities are not expected to be material. As discussed, EID is indemnified by Chemours under the Chemours Separation Agreement, as amended. The company has recorded a liability of $22 million and an indemnification asset of $22 million at September 30, 2019 , primarily related to testing drinking water in and around certain former EID sites and offering treatment or an alternative supply of drinking water if tests indicate the presence of PFOA in drinking water at or greater than the national health advisory level established from time to time by the EPA. Leach Settlement and MDL Settlement EID has residual liabilities under its 2004 settlement of a West Virginia state court class action, Leach v. EID, which alleged that PFOA from EID’s former Washington Works facility had contaminated area drinking water supplies and affected the health of area residents. The settlement class has about 80,000 members. In addition to relief that was provided to class members years ago, the settlement requires EID to continue providing PFOA water treatment to six area water districts and private well users and to fund, through an escrow account, up to $235 million for a medical monitoring program for eligible class members. As of September 30, 2019 , approximately $2 million had been disbursed from the account since its establishment in 2012 and the remaining balance is approximately $1 million . The Leach settlement permits class members to pursue personal injury claims for six health conditions (and no others) that an expert panel appointed under the settlement reported in 2012 had a “probable link” (as defined in the settlement) with PFOA: pregnancy-induced hypertension, including preeclampsia; kidney cancer; testicular cancer; thyroid disease; ulcerative colitis; and diagnosed high cholesterol. After the panel reported its findings, approximately 3,550 personal injury lawsuits were filed in federal and state courts in Ohio and West Virginia and consolidated in multi-district litigation in the U.S. District Court for the Southern District of Ohio (“MDL”). The MDL was settled in early 2017 for $670.7 million in cash, with Chemours and EID (without indemnification from Chemours) each paying half. Post-MDL Settlement PFOA Personal Injury Claims The MDL settlement did not resolve claims of plaintiffs who did not have claims in the MDL or whose claims are based on diseases first diagnosed after February 11, 2017. At September 30, 2019 , approximately 60 lawsuits were pending alleging personal injury, mostly kidney or testicular cancer, from exposure to PFOA through air or water, only 3 of which are not part of the MDL or were not filed on behalf of Leach class members. The first trial is scheduled to begin January 2020. Other PFOA Matters EID is a party to other PFOA lawsuits that do not involve claims for personal injury. Chemours, pursuant to the Chemours Separation Agreement, is defending and indemnifying, with reservation, EID but Chemours has refused the tender of Corteva, Inc.'s defense in the limited actions in which Corteva, Inc. has been named. Corteva believes that Chemours is obligated to indemnify Corteva, Inc. under the Chemours Separation Agreement. New York . EID is a defendant in 51 lawsuits, including a putative class action, brought by persons who live in and around Hoosick Falls, New York. These lawsuits assert claims for medical monitoring and property damage based on alleged PFOA releases from manufacturing facilities owned and operated by co-defendants in Hoosick Falls and allege that EID and 3M supplied some of the materials used at these facilities. EID is also one of more than ten defendants in a lawsuit brought by the Town of East Hampton, New York alleging PFOA and PFOS contamination of the town’s well water. New Jersey . At September 30, 2019 , two lawsuits were pending, one brought by a local water utility and the second a putative class action, against EID alleging that PFOA from EID’s former Chambers Works facility contaminated drinking water sources. The putative class action has since been voluntarily dismissed without prejudice by the plaintiff. In late March of 2019, the New Jersey State Attorney General filed four lawsuits against EID, Chemours, 3M and others alleging that operations at and discharges from former EID sites in New Jersey (Chambers Works, Pompton Lakes, Parlin and Repauno) damaged the State’s natural resources. Two of these lawsuits (those involving the Chambers Works and Parlin sites) allege contamination from PFAS. The Ridgewood Water District in New Jersey filed suit in the first quarter 2019 against EID alleging losses related to the investigation, remediation and monitoring of polyfluorinated surfactants, including PFOA, in water supplies. Alabama / Others . EID is one of more than thirty defendants in a lawsuit by the Alabama water utility alleging contamination from PFCs, including PFOA, used by co-defendant carpet manufacturers to make their products more stain and grease resistant. In addition, the states of New Hampshire, South Dakota, and Vermont recently filed lawsuits against EID, Chemours, 3M and others, claiming, among other things, PFC (including PFOA) contamination of groundwater and drinking water. The complaints seek reimbursement for past and future costs to investigate and remediate the alleged contamination and compensation for the loss of value and use of the state’s natural resources. Ohio . EID is a defendant in three lawsuits: an action by the State of Ohio based on alleged damage to natural resources, a putative nationwide class action brought on behalf of anyone who has detectable levels of PFAS in their blood serum, and an action by the City of Dayton claiming losses related to the investigation, remediation and monitoring of PFAS in water supplies. Other . Approximately 150 cases have been filed against 3M and other defendants alleging PFOS or PFOA contamination of soil and groundwater from the use of aqueous firefighting foams. Most of those cases claim some form of property damage and seek to recover the costs of responding to this contamination and damages for the loss of use and enjoyment of property and diminution in value. Most of these cases have been transferred to a multidistrict litigation proceeding in federal district court in South Carolina. At September 30, 2019 , EID was named in 32 of these cases. EID did not make firefighting foams, PFOS, or PFOS products. While EID made surfactants and intermediaries that some manufacturers used in making foams, which may have contained PFOA as an unintended byproduct or an impurity, EID’s products were not formulated with PFOA, nor was PFOA an ingredient of these products. EID has never made or sold PFOA as a commercial product. In addition, the company is aware of an inquiry by the Subcommittee on Environment of the House of Representatives to DuPont, Chemours and 3M regarding exposure to PFAS and has requested certain information related to PFAS. Fayetteville Works Facility, North Carolina Prior to the separation of Chemours, EID introduced GenX as a polymerization processing aid and a replacement for PFOA at the Fayetteville Works facility in Bladen County, North Carolina. The facility is now owned and operated by Chemours, which continues to manufacture and use GenX. In 2017, the facility became and continues to be the subject of inquiries and government investigations relating to the alleged discharge of GenX and certain similar compounds into the air and Cape Fear River. In August 2017, the U.S. Attorney’s Office for the Eastern District of North Carolina served EID with a grand jury subpoena for testimony and documents related to these discharges. EID was served with additional subpoenas relating to the same issue and in the second quarter 2018, received a subpoena expanding the scope to any PFCs discharged from the Fayetteville Works facility into the Cape Fear River. It is possible that these ongoing inquiries and investigations, including the grand jury subpoena, could result in penalties or sanctions, or that additional litigation will be instituted against Chemours, EID, or both. At September 30, 2019 , three actions are pending in federal court against Chemours and EID relating to PFC discharges from the Fayetteville Works facility. One of these is a consolidated putative class action that asserts claims for medical monitoring and property damage on behalf of putative classes of property owners and residents in areas near or who draw drinking water from the Cape Fear River. Another action is a consolidated action brought by various North Carolina water authorities, including the Cape Fear Public Utility Authority and Brunswick County, that seek actual and punitive damages as well as injunctive relief. The other action is on behalf of about 200 plaintiffs who own wells and property near the Fayetteville Works facility. The plaintiffs seek damages for nuisance allegedly caused by releases of certain PFCs from the site. The plaintiffs’ claims for medical monitoring, punitive damages, public nuisance, trespass, unjust enrichment, failure to warn, and negligent manufacture have all been dismissed. While it is reasonably possible that the company could incur liabilities related to the actions described above, any such liabilities are not expected to be material. The company has an indemnification claim against Chemours with respect to current and future inquiries and claims, including lawsuits, related to the foregoing. At September 30, 2019 , Chemours, with reservations, is defending and indemnifying EID in the pending civil actions. Environmental 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 based on current law and existing technologies. At September 30, 2019 , the company had accrued obligations of $349 million for probable environmental remediation and restoration costs, including $51 million for the remediation of Superfund sites. These obligations are included in accrued and other current liabilities and other noncurrent obligations in the interim Condensed Consolidated Balance Sheets. This is management’s best estimate of the costs for remediation and restoration with respect to environmental matters for which the company has accrued liabilities, although it is reasonably possible that the ultimate cost with respect to these particular matters could range up to $720 million above the amount accrued at September 30, 2019 . Consequently, it is reasonably possible that environmental remediation and restoration costs in excess of amounts accrued could have a material impact on the company’s results of operations, financial condition and cash flows. Inherent uncertainties exist in these estimates primarily due to unknown conditions, changing governmental regulations and legal standards regarding liability, and emerging remediation technologies for handling site remediation and restoration. For a discussion of the allocation of environmental liabilities under the Chemours Separation Agreement and the Corteva Separation Agreement, see the previous discussion on page 41. The above noted $349 million accrued obligations includes the following: As of September 30, 2019 (In millions) Indemnification Asset Accrual balance 3 Potential exposure above amount accrued 3 Environmental Remediation Stray Liabilities Chemours related obligations - subject to indemnity 1,2 $ 170 $ 170 $ 383 Other discontinued or divested businesses obligations 1 — 102 224 Environmental remediation liabilities primarily related to DuPont - subject to indemnity from DuPont 34 34 61 Environmental remediation liabilities not subject to indemnity — 43 52 Total $ 204 $ 349 $ 720 1. Represents liabilities that are subject the $200 million thresholds and sharing arrangements as discussed on page 41, under Corteva Separation Agreement. 2. The company has recorded an indemnification asset related to these accruals, including $30 million related to the Superfund sites. 3. Accrual balance represents management’s best estimate of the costs of remediation and restoration, although it is reasonably possible that the potential exposure, as indicated, could range above the amounts accrued, as there are inherent uncertainties in these estimates. |
