For additional information see Note 13 - Commitments and Contingent Liabilities. DuPont Pursuant to the Separation Agreements, DuPont and Corteva indemnifies the other against certain litigation, environmental, tax, workers' compensation and other liabilities that arose prior to the Corteva Distribution. The term of this indemnification is generally indefinite and includes defense costs and expenses, as well as monetary and non-monetary settlements and judgments. In connection with the recognition of liabilities related to these matters, the company records an indemnification asset when recovery is deemed probable. At June 30, 2021, the indemnification assets are $31 million within accounts and notes receivable - net and $50 million within other assets in the interim Consolidated Balance Sheet. At June 30, 2021, the indemnification liabilities are $77 million within other noncurrent obligations in the interim Consolidated Balance Sheet. Dow Pursuant to the Separation Agreements, Dow and Corteva indemnifies the other against certain litigation, environmental, tax and other liabilities that arose prior to the Corteva Distribution. The term of this indemnification is generally indefinite and includes defense costs and expenses, as well as monetary and non-monetary settlements and judgments. In connection with the recognition of liabilities related to these matters, the company records an indemnification asset when recovery is deemed probable. At June 30, 2021, the indemnification liabilities are $54 million within accrued and other current liabilities and $14 million within other noncurrent obligations in the interim Consolidated Balance Sheet. Performance Chemicals On July 1, 2015, Historical DuPont completed the separation of its Performance Chemicals segment through the spin-off of all of the issued and outstanding stock of The Chemours Company (the "Chemours Separation"). In connection with the Chemours Separation, Historical DuPont and The Chemours Company ("Chemours") entered into a Separation Agreement (as amended, the "Chemours Separation Agreement"), discussed below, a Tax Matters Agreement and certain ancillary agreements, including an employee matters agreement, agreements related to transition and site services, and intellectual property cross licensing arrangements. In addition, the companies entered into certain supply agreements. Chemours Separation Agreement The Chemours Separation Agreement sets forth, among other things, the agreements between the company and Chemours regarding the principal transactions necessary to affect the Chemours Separation and also sets forth ancillary agreements that govern certain aspects of the company’s relationship with Chemours after the separation. Among other matters, the Chemours Separation Agreement and the ancillary agreements provide for the allocation between Historical DuPont and Chemours of assets, employees, liabilities and obligations (including investments, property and employee benefits and tax-related assets and liabilities) attributable to periods prior to, at and after the completion of the Chemours Separation. Pursuant to the Chemours Separation Agreement, Chemours indemnifies the company against certain litigation, environmental, workers' compensation and other liabilities that arose prior to the distribution. The term of this indemnification is generally indefinite and includes defense costs and expenses, as well as monetary and non-monetary settlements and judgments. In 2017, EID and Chemours amended the Chemours Separation Agreement ("2017 Amendment") to provide for a limited sharing of potential future perfluorooctanoic acid (“PFOA”) liabilities for a period of five years beginning July 6, 2017. In January 2021, Chemours, DuPont and Corteva entered into a binding memorandum of understanding ("MOU") amending the Chemours Separation Agreement, and thereby replacing the 2017 Amendment. In connection with the recognition of liabilities related to these matters, the company records an indemnification asset when recovery is deemed probable. At June 30, 2021, the indemnification assets are $64 million within accounts and notes receivable - net and $255 million within other assets (along with the corresponding liabilities within accrued and other current liabilities and other noncurrent obligations in the interim Consolidated Balance Sheet). At June 30, 2021 indemnification liabilities related to the MOU, primarily associated with environmental remediation related to PFAS, were $24 million within accrued and other current liabilities and $75 million within other noncurrent obligations in the interim Consolidated Balance Sheet. During the three and six months ended June 30, 2021, the company recorded charges of $34 million and $37 million, respectively, to (loss) income from discontinued operations after income taxes, related to the MOU. The charge in the three months ended June 30, 2021 is primarily related to an increase in the environmental remediation accrual for Chemours' Fayetteville Works facility for estimated costs for on-site surface water and groundwater remediation to address and abate PFAS discharges arising out of pre-July 1, 2015 conduct. The increase is the result of further detailed engineering and design work related to Chemours’ environmental remediation activities at the site under the Consent Order between Chemours and the North Carolina Department of Environmental Quality. Based on the upper end of the range of reasonably possible outcomes, the company’s potential exposure above the amount accrued relating to the Fayetteville Works facility is approximately $20 million at June 30, 2021. In addition to the above, the company has recognized a liability of $12.5 million as of June 30, 2021 within accrued and other current liabilities in the interim Consolidated Balance Sheet related to the settlement agreement between Chemours, DuPont, EID, Corteva and the State of Delaware. During the three months ended June 30, 2021, the company recorded a charge of $11 million to (loss) income from discontinued operations after income taxes, related to the settlement. See Note 13 - Commitments and Contingent Liabilities, to the interim Consolidated Financial Statements, for further discussion of the amendment to the Chemours Separation Agreement, MOU, environmental matters indemnified by Chemours and the settlement with the State of Delaware.
